PureCycle Technologies, Inc.

4.75% Convertible Senior Notes due 2032

We are offering $250,000,000 principal amount of our 4.75% Convertible Senior Notes due 2032 (the “notes”). The notes will bear interest at a rate of 4.75% per year, payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2027. The notes will mature on July 1, 2032, unless earlier converted, redeemed or repurchased.

Holders may convert all or any portion of their notes at their option at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock, par value $0.001 per share (our “common stock”) or a combination of cash and shares of our common stock, at our election, as described in this prospectus supplement.

The conversion rate will initially be 90.2242 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $11.08 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called (or deemed called) for redemption during the related redemption period (as defined in this prospectus supplement), as the case may be.

We may not redeem the notes prior to July 6, 2029. We may redeem for cash all or any portion of the notes (subject to the partial redemption limitation described in this prospectus supplement), at our option, on a redemption date on or after July 6, 2029 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the notes.

On July 8, 2030 or if we undergo a “fundamental change” (as defined in this prospectus supplement), then, subject to certain conditions and except as described in this prospectus supplement, holders may require us to repurchase for cash all or any portion of their notes at a specified repurchase date repurchase price or fundamental change repurchase price, as applicable, equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the relevant repurchase date.

Concurrently with this offering, we are conducting an underwritten public offering (the “Concurrent Stock Offering”) of 17,570,200 shares of our common stock (or up to 19,854,000 shares of our common stock if the underwriters in the Concurrent Stock Offering exercise their option to purchase additional shares in full) at a price of $8.21 per share pursuant to a separate prospectus supplement. We expect to use a portion of the net proceeds from this offering and the Concurrent Stock Offering, if consummated, to repurchase for cash approximately $216.0 million in aggregate principal amount at maturity of our 7.25% Green Convertible Senior Notes due 2030 (the “Green Convertible Notes”) including $50.0 million in aggregate principal amount at

maturity of Green Convertible Notes held by certain entities affiliated with Sylebra Capital Management (the “affiliated investors”), in privately negotiated transactions (the “Note Repurchase Transactions”). No assurance can be given as to how much, if any, of the Green Convertible Notes will be repurchased or the terms on which they will be repurchased. Neither the completion of this offering nor the Concurrent Stock Offering is contingent on the completion of the other or the Note Repurchase Transactions. No assurance can be given that the Concurrent Stock Offering will be completed on the terms described herein or at all. This prospectus supplement does not constitute an offer to sell, or the solicitation of an offer to buy, any shares of our common stock in the Concurrent Stock Offering, and does not constitute an offer to buy, or the solicitation of an offer to sell, any of the Green Convertible Notes.

We do not intend to apply to list the notes on any securities exchange or any automated dealer quotation system. Our common stock is listed on the Nasdaq Capital Market (“Nasdaq”) under the symbol “PCT”. The last reported sale price of our common stock on June 9, 2026 was $10.80 per share.

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully read and consider the risks and uncertainties described under the caption “Risk Factors” beginning on page S-10 of this prospectus supplement and on page 5 of the accompanying prospectus, as well as the risks and uncertainties described in the documents incorporated by reference herein and therein, including the risk factors incorporated by reference from our most recent Annual Report on Form 10-K and, where applicable, subsequent Quarterly Reports on Form 10-Q.

We have granted the underwriters the right to purchase, exercisable within a 30-day period, up to an additional $37,500,000 principal amount of notes, solely to cover over-allotments.

We expect that delivery of the notes will be made to investors in book-entry form through The Depository Trust Company on or about June 15, 2026, which will be the second business day following the initial trade date for the notes offered pursuant to this prospectus supplement (this settlement cycle being referred to as “T+2”). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes offered hereby prior to the business day preceding the settlement date will be required, by virtue of the fact that the notes initially will settle T+2, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to the business day preceding the settlement date should consult their own advisors.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

We are offering to sell our notes only in jurisdictions where offers and sales are permitted. The distribution of this prospectus supplement and the accompanying prospectus and the offering of the notes in certain jurisdictions may be restricted by law. Persons outside the United States who come into possession of this prospectus supplement or the accompanying prospectus must inform themselves about, and observe any restrictions relating to, the offering of the notes and the distribution of this prospectus supplement and the accompanying prospectus outside the United States.

PROSPECTUS SUPPLEMENT SUMMARY

This summary highlights certain information about us, this offering and selected information contained elsewhere in or incorporated by reference into this prospectus supplement and the accompanying prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in the notes. For a more complete understanding of our Company and this offering, we encourage you to read and consider carefully the more detailed information in this prospectus supplement and the accompanying prospectus, including the information incorporated by reference in this prospectus supplement and the accompanying prospectus, and the information included in any free writing prospectus that we have authorized for use in connection with this offering, including the information under the caption “Risk Factors” in this prospectus supplement, the accompanying prospectus and in the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. When used in this prospectus supplement, the terms “we,” “us,” “our,” “PCT” and “the Company” mean PureCycle Technologies, Inc. and its consolidated subsidiaries, collectively.

The Company

PCT is a Florida-based corporation focused on commercializing a patented dissolution recycling technology for polypropylene to physically separate the polymer from other plastics, colors, odors, and impurities (the “Technology”). The Technology was originally developed by The Procter & Gamble Company (“P&G”), for restoring waste polypropylene into resin, called PureFive^® resin, which has similar properties and applicability for reuse as virgin polypropylene. PCT has a global license for the Technology from P&G (the “P&G license”), which was amended during 2025 to permanently waive the possible clawback of PCT’s exclusivity for plants located in North America and extend the time in which PCT’s plants must begin construction and commence sales in other regions to avoid a clawback of exclusivity under the Amended and Restated Patent License Agreement, dated July 28, 2020 (as amended, the “License Agreement”). PCT has introduced an important new product to the global polypropylene market that will assist corporations in meeting their sustainability goals as well as federal and state regulations and mandates, providing consumers with polypropylene-based products that are sustainable, and reducing overall polypropylene waste in the world’s landfills and oceans.

PCT’s process includes the following steps: Feed Pre-Processing (“Feed PreP”), and the use of PCT’s recycling technology for purification and compounding. The Feed PreP step collects, sorts, and prepares polypropylene waste (“feedstock”) for the dissolution recycling process (“Purification”). The Purification step is a dissolution recycling process that uses a combination of solvent, temperature, and pressure to return the feedstock to near-virgin condition through a novel configuration of commercially-available equipment and unit operations. The Purification process puts the plastic through a physical extraction process using supercritical fluids that both extract and filter out other plastics and additives to purify the color, opacity, and odor of the plastic without changing the bonds of the polymer. By not altering the chemical makeup of the polymer, PCT is able to use significantly less energy and reduce production costs as compared to virgin resin. Compounding, which involves blending PCT’s resin with either virgin resin or additives, is a step that can be used on a case-by-case basis. Compounding allows for the modification of the resin to meet the end-user’s qualifications with melt flow, flexibility, clarity, color and strength.

Recent Developments

Concurrent Offering of Common Stock and Note Repurchase Transactions

Concurrently with this offering, we are conducting an underwritten public offering of 17,570,200 shares of our common stock (or up to 19,854,000 shares of our common stock if the underwriters in the Concurrent Stock Offering exercise their option to purchase additional shares in full) at a price of $8.21 per share pursuant to a separate prospectus supplement. We expect to use a portion of the net proceeds from this offering and the Concurrent

S-1

Stock Offering, if consummated, to repurchase for cash approximately $216.0 million in aggregate principal amount at maturity of the Green Convertible Notes, including $50.0 million in aggregate principal amount at maturity of the Green Convertible Notes held by the affiliated investors, in the Note Repurchase Transactions, which we entered into concurrently with the pricing of this offering.

No assurance can be given as to how much, if any, of the Green Convertible Notes will be repurchased or the terms on which they will be repurchased. Neither the completion of this offering nor the Concurrent Stock Offering is contingent on the completion of the other or the Note Repurchase Transactions. No assurance can be given that the Concurrent Stock Offering will be completed on the terms described herein or at all. This prospectus supplement does not constitute an offer to sell, or the solicitation of an offer to buy, any shares of our common stock in the Concurrent Stock Offering, and does not constitute an offer to buy, or the solicitation of an offer to sell, any of the Green Convertible Notes.

After giving effect to the Note Repurchase Transactions, approximately $34.0 million aggregate principal amount at maturity of the Green Convertible Notes are expected to remain outstanding.

In connection with any Note Repurchase Transaction, we expect that the holders of the Green Convertible Notes who agree to have their Green Convertible Notes repurchased and who have hedged their equity price risk with respect to such notes (the “hedged holders”) will unwind all or part of their hedge positions by buying shares of our common stock, including pursuant to the Concurrent Stock Offering, and/or entering into or unwinding various derivative transactions with respect to our common stock. The amount of our common stock to be purchased by the hedged holders or in connection with such derivative transactions may be substantial in relation to the historic average daily trading volume of our common stock. This activity by the hedged holders could increase (or reduce the size of any decrease in) the market price of our common stock, including concurrently with the pricing of the notes, which could result in a higher effective conversion price for the notes. We cannot predict the magnitude of such market activity or the overall effect it will have on the price of the notes offered hereby or our common stock. See the caption “Risk Factors—Risks Related to the Notes and This Offering—Any repurchases of the Green Convertible Notes may affect the value of the notes and our common stock” and “The Concurrent Transactions.”

Amendment to Revolving Credit Agreement

We are party to that certain Credit Agreement (as amended, the “Revolving Credit Agreement”) dated as of March 15, 2023, with PureCycle Technologies Holdings Corp., PureCycle Technologies, LLC, PureCycle Augusta, LLC and PureCycle (Thailand) Company Limited (collectively, the “Revolving Credit Facility Guarantors”), Sylebra Capital Partners Master Fund, LTD, Sylebra Capital Parc Master Fund, and Sylebra Capital Menlo Master Fund (collectively, the “Lenders”), and Kroll Trustee Services (HK) Limited (the “Administrative Agent” and “Security Agent”), providing the Company with a revolving credit facility pursuant to which the Company can borrow up to $200 million (the “Revolving Credit Facility”). On June 10, 2026, the Company, the Revolving Credit Facility Guarantors, the Administrative Agent, the Security Agent and the Lenders executed a Limited Consent and Eleventh Amendment to Credit Agreement, which amends the Revolving Credit Agreement to, among other things, (i) permit this offering and the Concurrent Stock Offering and (ii) remove as secured obligations certain obligations in respect of the Company’s Series A Preferred Stock, par value $0.001 per share (“Series A Preferred Stock”), Series C Warrants and Pre-Funded Warrants, in each case, owed by the affiliated investors.

New Jersey Recycled Content Approval

On May 14, 2026, the New Jersey Department of Environmental Protection (“NJDEP”) designated PCT’s PureFive^® resin as “postconsumer recycled content” (“PCR”) under the state of New Jersey’s Recycled Content Law (the “Recycled Content Law”).

S-2

The Recycled Content Law requires manufacturers of rigid plastic containers, beverage containers and other regulated packaging to meet minimum thresholds of postconsumer recycled content. The mandates started at 10% for rigid plastics in 2024 and rise by 10% every three years until reaching 50% in 2036. Food-contact packaging is exempt from the new regulations until 2027.

NJDEP’s PCR designation is a one-year conditional approval. During the 12 month period following receipt of conditional approval on May 14, 2026, PCT expects to provide NJDEP with documentation of feedstock sources, the type of feedstock processed, PureFive^® end-use applications, as well as certain compliance information as requested as part of the permanent approval process.

Thailand Facility

PCT plans to construct a 130 million pound polypropylene recycling facility in Rayong, Thailand (the “Thailand Facility”). PCT intends to develop the facility at the IRPC Public Company Limited (“IRPC”) eco-industrial zone in Rayong. IRPC is an integrated petrochemical operator in Southeast Asia. Its production structure comprises petroleum and petrochemical complexes, complete with utilities and infrastructure supporting the operations, including a deep-sea port and ample steam and power capacity. PCT intends to leverage this existing site infrastructure to reduce the costs of certain construction activities. The permitting process has begun for the Thailand Facility, and the Thailand Facility is expected to be completed in late 2027. PCT currently estimates a total investment of $250 million for the Thailand Facility and is seeking project financing to fund a portion of the investment.

THE OFFERING

The summary below describes the principal terms of the notes. Certain of the terms and conditions described below are subject to important limitations and exceptions. The “Description of Debt Securities” section of the accompanying prospectus, as supplemented by the “Description of Notes” section of this prospectus supplement, contains a more detailed description of the terms and conditions of the notes. As used in this section, “we,” “our,” and “us” refer to PureCycle Technologies, Inc. and not to its consolidated subsidiaries, and the common stock of PureCycle Technologies, Inc., par value $0.001 per share, is referred to as our “common stock.”

Issuer

PureCycle Technologies, Inc., a Delaware corporation.

Securities

$250,000,000 principal amount of 4.75% Convertible Senior Notes due 2032.

Over-Allotment Option

We have granted to the underwriters an over-allotment option to purchase up to $37,500,000 aggregate principal amount of additional notes (equal to 15% of the aggregate principal amount of initial notes offered hereby).

Maturity

July 1, 2032, unless earlier converted, redeemed or repurchased.

Interest

4.75% per year. Interest will accrue from June 15, 2026 and will be payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2027. We will pay additional interest, if any, at our election as the sole remedy relating to the failure to comply with our reporting obligations as described under the caption “Description of Notes—Events of Default.”

Conversion Rights

Holders may convert all or any portion of their notes, in integral multiples of $1,000 principal amount, at their option at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date.

The conversion rate for the notes is initially 90.2242 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $11.08 per share of common stock), subject to adjustment as described in this prospectus supplement.

Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. If we satisfy our conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of our common stock, the amount of cash and shares of common stock, if any, due upon conversion will be based on a “daily conversion value” (as defined under the caption “Description of Notes—Conversion Rights—Settlement upon Conversion”) calculated on a proportionate basis for each trading day in a 30 trading day “observation period” (as defined under the caption “Description of Notes—Conversion

S-4

Rights—Settlement upon Conversion”). See the caption “Description of Notes—Conversion Rights—Settlement upon Conversion.”

In addition, following certain corporate events that occur prior to the maturity date or if we deliver a notice of redemption, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or convert its notes called (or deemed called) for redemption during the related redemption period (as defined under the caption “Description of Notes—Conversion Rights—General”), as the case may be, as described under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption.”

You will not receive any additional cash payment or additional shares representing accrued and unpaid interest, if any, upon conversion of a note, except in limited circumstances. Instead, interest will be deemed to be paid by the cash, shares of our common stock or a combination of cash and shares of our common stock paid or delivered, as the case may be, to you upon conversion of a note.

Redemption at Our Option

We may not redeem the notes prior to July 6, 2029. We may redeem for cash all or any portion of the notes (subject to the partial redemption limitation described in the next succeeding sentence), at our option, on a redemption date on or after July 6, 2029 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If we redeem less than all the outstanding notes, at least $75.0 million aggregate principal amount of notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption. No “sinking fund” is provided for the notes, which means that we are not required to redeem or retire the notes periodically. See the caption “Description of Notes—Optional Redemption.”

Specified Repurchase Date Repurchase

On July 8, 2030 (the “specified repurchase date”), holders may require us to repurchase for cash all or any portion of their notes in principal amounts of $1,000 or an integral multiple thereof at a repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the specified repurchase date (the “specified repurchase date repurchase price”). See the caption “Description of Notes—Repurchase at the Option of Holders—Repurchase on July 8, 2030.”

S-5

Fundamental Change

If we undergo a “fundamental change” (as defined under the caption “Description of Notes—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes”), then, subject to certain conditions and except as described in this prospectus supplement, holders may require us to repurchase for cash all or any portion of their notes in principal amounts of $1,000 or an integral multiple thereof. The fundamental change repurchase price will be equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. See the caption “Description of Notes—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes.”

Ranking

The notes will be our general unsecured obligations and will rank:

See the caption “Description of Other Indebtedness” in this prospectus supplement for a description of the material terms of the Green Convertible Notes, Revolving Credit Facility and Revenue Bonds.

As of March 31, 2026, the outstanding principal amount of our total consolidated indebtedness for borrowed money was approximately $403.8 million, of which approximately $153.8 million was secured indebtedness consisting of the Revenue Bonds and certain equipment financing. As of March 31, 2026, our subsidiaries had approximately $248.9 million of liabilities (including trade payables, but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP) to which the notes would have been structurally subordinated. After giving effect to the issuance of the notes (assuming no exercise

S-6

of the underwriters’ over-allotment option and without giving effect to the use of the proceeds therefrom), the outstanding principal amount of our total consolidated indebtedness for borrowed money as of March 31, 2026 would have been $653.8 million.

The indenture that will govern the notes will not limit the amount of debt or other liabilities that we or our current or future subsidiaries may incur.

Use of Proceeds

We estimate that the net proceeds from this offering will be approximately $242.0 million (or approximately $278.3 million if the underwriters exercise their over-allotment option in full), after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

We expect to use the net proceeds from this offering, together with the net proceeds from the Concurrent Stock Offering, if consummated: (i) to pay the approximately $246.3 million cost of repurchasing for cash approximately $216.0 million in aggregate principal amount at maturity of the Green Convertible Notes in the Note Repurchase Transactions as described below under the caption “The Concurrent Transactions”; (ii) to repurchase additional Green Convertible Notes from time to time; and (iii) for working capital and other general corporate purposes. See the caption “Use of Proceeds.”

Note Repurchase Transactions

Concurrently with the pricing of the notes in this offering, we entered into privately negotiated transactions to repurchase for cash approximately $216.0 million in aggregate principal amount at maturity of the Green Convertible Notes (including $50.0 million in aggregate principal amount at maturity of the Green Convertible Notes held by the affiliated investors) for approximately $246.3 million (including approximately $57.0 million payable to the affiliated investors). No assurance can be given as to how much, if any, of the Green Convertible Notes will be repurchased or the terms on which they will be repurchased. Neither the completion of this offering nor the Concurrent Stock Offering is contingent on the completion of the other or the Note Repurchase Transactions. This prospectus supplement does not constitute an offer to buy, or the solicitation of an offer to sell, any of our Green Convertible Notes.

reduce the size of any decrease in) the market price of our common stock, including concurrently with the pricing of the notes, which could result in a higher effective conversion price for the notes. We cannot predict the magnitude of such market activity or the overall effect it will have on the price of the notes offered hereby or our common stock. See the caption “Risk Factors—Risks Related to the Notes and This Offering—Any repurchases of the Green Convertible Notes may affect the value of the notes and our common stock.”

See the caption “The Concurrent Transactions” for a further description of the Note Repurchase Transactions.

Concurrent Stock Offering

Neither the completion of this offering nor the Concurrent Stock Offering is contingent on the completion of the other or the Note Repurchase Transactions. No assurance can be given that the Concurrent Stock Offering will be completed on the terms described herein or at all This prospectus supplement does not constitute an offer to sell, or the solicitation of an offer to buy, any shares of our common stock in the Concurrent Stock Offering.

See the caption “The Concurrent Transactions” for a further description of the Concurrent Stock Offering.

Book-Entry Form

The notes will be issued in book-entry form and will be represented by permanent global certificates deposited with, or on behalf of, The Depository Trust Company (“DTC”), and registered in the name of a nominee of DTC. Beneficial interests in any of the notes will be shown on, and transfers will be effected only through, records maintained by DTC or its nominee and any such interest may not be exchanged for certificated securities, except in limited circumstances.

Absence of a Public Market for the Notes

The notes are new securities, and there is currently no established market for the notes. Accordingly, we cannot assure you as to the development or liquidity of any market for the notes. Certain of the underwriters have advised us that they currently intend to make a market in the notes. However, they are not obligated to do so, and they may discontinue any market making with respect to the notes without notice. We do not intend to apply for a listing of the notes on any securities exchange or any automated dealer quotation system.

Governing Law

The indenture and the notes, and any claim, controversy or dispute arising under or related to the indenture or the notes, will be governed by and construed in accordance with the laws of the State of New York.

Risk Factors

Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully read and consider the risks and uncertainties described under the caption “Risk Factors” beginning on page S-10 of this prospectus supplement and on page 5 of the accompanying prospectus, as well as the risks and uncertainties described in the documents incorporated by reference herein, including the risk factors incorporated by reference from our most recent Annual Report on Form 10-K and, where applicable, subsequent Quarterly Reports on Form 10-Q.

S-9

RISK FACTORS

Investing in our securities involves risk. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed under the caption “Risk Factors” in our most recent Annual Report on Form 10-K for the year ended December 31, 2025 (the “Annual Report”) and our other filings with the SEC from time to time, which are incorporated by reference in this prospectus supplement and the accompanying prospectus and may be amended, supplemented or superseded from time to time by our Quarterly Reports on Form 10-Q and other reports we file with the SEC in the future. The risks and uncertainties we have described are not the only risks to which we are exposed. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. If any of these risks actually occur, our business, results of operations and financial condition could suffer. In that case, the trading price of our securities could decline, and you could lose all or a part of your investment.

Risks Related to the Notes and This Offering

The notes are effectively subordinated to our secured debt and any liabilities of our subsidiaries.

The notes will be our general unsecured obligations and will rank senior in right of payment to all of our indebtedness that is expressly subordinated in right of payment to the notes; equal in right of payment with all of our existing and future liabilities that are not so subordinated, including the Green Convertible Notes; effectively junior to any of our secured indebtedness (including all secured debt we incur in the future) to the extent of the value of the assets securing such indebtedness, including any borrowings under the Revolving Credit Facility; and structurally junior to all indebtedness and other liabilities (including trade payables) of our current or future subsidiaries, including the Revenue Bonds. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure debt ranking senior or equal in right of payment to the notes will be available to pay obligations on the notes only after the secured debt has been repaid in full from such assets. There may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding. The indenture governing the Green Convertible Notes does not, and the indenture that will govern the notes will not, prohibit us from incurring additional senior debt or secured debt, nor does it prohibit any of our current or future subsidiaries from incurring additional liabilities.

The notes are our obligations only, and substantially all of our operations are conducted through, and substantially all of our consolidated assets are held by, our subsidiaries.

The notes are our obligations exclusively and are not guaranteed by any of our operating subsidiaries. Substantially all of our operations are conducted through, and substantially all of our consolidated assets are held by, our subsidiaries. Accordingly, our ability to service our debt, including the notes, depends on the results of operations of our subsidiaries and upon the ability of such subsidiaries to provide us with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the notes. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the notes or to make any funds available for that purpose. In addition, dividends, loans or other distributions to us from such subsidiaries may be subject to contractual and other restrictions, including restrictions in the Revolving Credit Facility and any of our future debt instruments, and are subject to other business considerations.

S-10

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt, including the notes.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the notes, and to pay cash amounts due upon conversion of the notes, depends on our future performance, which is subject to economic, financial, competitive and other factors, many of which are beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, refinancing or restructuring debt or obtaining additional debt financing or equity capital on terms that may be onerous or highly dilutive. Our ability to refinance or restructure our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, any of our existing or future debt agreements may contain restrictive covenants that may prohibit us from adopting any of these alternatives. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of our debt.

Regulatory actions and other events may adversely affect the trading price and liquidity of the notes.

We expect that many investors in, and potential purchasers of, the notes will employ, or seek to employ, a convertible arbitrage strategy with respect to the notes. Investors would typically implement such a strategy by selling short the common stock underlying the notes and dynamically adjusting their short position while continuing to hold the notes. Investors may also implement this type of strategy by entering into swaps on our common stock in lieu of or in addition to short selling shares of common stock. We cannot assure you that market conditions will permit investors to implement this type of strategy, on favorable terms or at all. If market conditions do not permit investors to implement this type of strategy, on favorable terms or at all, at any time while the notes are outstanding, the trading price and liquidity of the notes may be adversely affected.

The SEC and other regulatory and self-regulatory authorities have implemented various rules and taken certain actions, and may in the future adopt additional rules and take other actions, that may affect those engaging in short selling activity involving equity securities (including our common stock). Such rules and actions include Rule 201 of SEC Regulation SHO, the adoption by the Financial Industry Regulatory Authority, Inc. and the national securities exchanges of a “Limit Up-Limit Down” program, the imposition of market-wide circuit breakers that halt trading of securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Any governmental or regulatory action that restricts or otherwise affects the ability of investors in, or potential purchasers of, the notes to effect short sales of our common stock, borrow shares of our common stock or enter into swaps on our common stock could adversely affect the trading price and the liquidity of the notes.

In addition, the number of shares of our common stock available for lending in connection with short sale transactions and the number of counterparties willing to enter into an equity swap on our common stock with a note investor may not be sufficient for the implementation of a convertible arbitrage strategy. These and other market events could make implementing a convertible arbitrage strategy prohibitively expensive or infeasible. We cannot assure you that a sufficient number of shares of our common stock will be available to borrow on commercial terms, or at all, to potential purchasers in this offering or holders of the notes. If investors in this offering or potential purchasers of the notes that seek to employ a convertible arbitrage strategy are unable to do so on commercial terms, or at all, then the trading price of, and the liquidity of the market for, the notes may significantly decline.

Volatility in the market price and trading volume of our common stock, the condition of the financial markets, prevailing interest rates and other factors could adversely affect the trading price of the notes.

We expect that the trading price of the notes will be significantly affected by the market price of our common stock. The stock market in recent years has experienced significant price and volume fluctuations that

S-11

have often been unrelated to the operating performance of companies. The market price of our common stock has been and may continue to be highly volatile and could fluctuate or decline significantly for many reasons, including in response to the risks described in this section, elsewhere in this prospectus supplement or in the documents we have incorporated by reference in this prospectus supplement or for reasons unrelated to our operations, many of which are beyond our control, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability and other factors not currently known to us or that we do not currently believe are material.

A decrease in the market price of our common stock would likely adversely impact the trading price of the notes. The market price of our common stock could also be affected by possible sales of our common stock by investors who view the notes as a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our common stock. This trading activity could, in turn, affect the trading price of the notes. In addition, if investors and potential purchasers seeking to employ a convertible arbitrage strategy are unable to borrow or enter into swaps on our common stock, in each case on commercially reasonable terms, the trading price and liquidity of the notes may be adversely affected.

In addition, the condition of the financial markets and changes in prevailing interest rates can have an adverse effect on the trading price of the notes. In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Consequently, if you purchase the notes and market interest rates increase, the market value of your notes may decline. We cannot predict the future level of market interest rates.

Despite our current debt levels, we may still incur substantially more debt or take other actions following this offering, which would intensify the risks discussed above.

Despite our current consolidated debt levels, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our existing or future debt instruments, some of which may be secured debt. We are not restricted under the terms of the indenture governing the Green Convertible Notes, and will not be restricted under the terms of the indenture that will govern the notes offered hereby from incurring additional debt, securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the applicable indenture governing the notes or the Green Convertible Notes that could have the effect of diminishing our ability to make payments on our debt, including the notes, when due. The credit agreement governing the Revolving Credit Facility restricts our ability to incur additional indebtedness, including secured indebtedness, but if the facility matures or is otherwise terminated, we may not be subject to such restrictions under the terms of any subsequent indebtedness.

We may not have the ability to raise the funds necessary to settle conversions of the notes or the Green Convertible Notes in cash or to repurchase the notes on July 8, 2030, the Green Convertible Notes on August 15, 2027 or the notes or the Green Convertible Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the notes or the Green Convertible Notes.

Holders of the notes will have the right, subject to certain conditions and limited exceptions, to require us to repurchase all or a portion of their notes on July 8, 2030 or upon the occurrence of a fundamental change at a specified repurchase date repurchase price or fundamental change repurchase price, as applicable, equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date, as described under the caption “Description of Notes—Repurchase at the Option of Holders.” In addition, upon any conversion of the notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the notes being converted as described under the caption “Description of Notes—Conversion Rights—Settlement upon Conversion.” The indenture governing the Green

S-12

Convertible Notes contains similar provisions requiring us to offer to repurchase the Green Convertible Notes on August 15, 2027 or upon the occurrence of a “fundamental change” (as defined in the indenture governing the Green Convertible Notes) and gives us the option to pay cash to settle conversions of the Green Convertible Notes. We may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of the notes or the Green Convertible Notes surrendered therefor or pay cash with respect to the notes or the Green Convertible Notes being converted. In addition, our ability to repurchase the notes or the Green Convertible Notes or to pay cash upon conversions of the notes or the Green Convertible Notes may be limited by law, by regulatory authority or by agreements governing our then-existing indebtedness. Our failure to repurchase the notes or the Green Convertible Notes at a time when the repurchase is required by the respective indenture or to pay any cash payable on future conversions of the notes as required by the respective indenture would constitute a default under the indenture or the indenture governing the Green Convertible Notes, as applicable. A default under either indenture or the fundamental change itself could also lead to a default under agreements governing our then-existing indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes or the Green Convertible Notes or make cash payments upon conversions thereof.

Our Revolving Credit Facility limits our ability to pay any cash amount upon the conversion or repurchase of the notes.

Our Revolving Credit Facility prohibits us from making any cash payments on the conversion or repurchase of the notes. See the caption “Description of Other Indebtedness—Description of Revolving Credit Facility.” Any new credit facility that we may enter into may have similar restrictions. Our failure to make cash payments upon the conversion or repurchase of the notes as required under the terms of the notes would permit holders of the notes to accelerate our obligations under the notes.

Redemption may adversely affect your return on the notes.

We may not redeem the notes prior to July 6, 2029. We may redeem for cash all or any portion of the notes (subject to the “partial redemption limitation” described under the caption “Description of Notes—Optional Redemption”), at our option, on a redemption date on or after July 6, 2029 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. As a result, we may choose to redeem some or all of the notes, including at times when prevailing interest rates are relatively low. As a result, you may not be able to reinvest the proceeds you receive from the redemption in a comparable security at an effective interest rate as high as the interest rate on your notes being redeemed. In addition, despite the partial redemption limitation, a redemption of less than all of the outstanding notes will likely harm the liquidity of the market for the unredeemed notes following the redemption. Accordingly, if your notes are not redeemed in a partial redemption, then you may be unable to sell your notes at the times you desire or at favorable prices, if at all, and the trading price of your notes may decline.

If you convert your notes, the consideration we deliver may not fully compensate you for any future interest payments that you would have otherwise received or any other lost time value of your notes. See the caption “Description of Notes—Optional Redemption.”

Our management has broad discretion over the use of proceeds from this offering and the proceeds from the Concurrent Stock Offering, if consummated, and we may use the proceeds in ways that may not generate a favorable return for us or improve our operating results.

Our management has significant flexibility in applying the net proceeds that we receive from this offering. We expect to use the net proceeds from this offering, together with the net proceeds from the Concurrent Stock

S-13

Offering, if consummated: (i) to pay the approximately $246.3 million cost of repurchasing for cash approximately $216.0 million in aggregate principal amount at maturity of the Green Convertible Notes in the Note Repurchase Transactions as described below under the caption “The Concurrent Transactions”; (ii) to repurchase additional Green Convertible Notes from time to time; and (iii) for working capital and other general corporate purposes. See the caption “Use of Proceeds.” However, the net proceeds are not required to be allocated to any specific purpose, and you will be unable to determine in advance the value or propriety of our management’s application of such net proceeds on our behalf. In addition, the net proceeds of this offering may not generate a favorable return for us or improve our operating results.

Conversion of the notes, the Green Convertible Notes and the Series B Convertible Preferred Stock (as defined below) may dilute the ownership interest of our stockholders or may otherwise depress the price of our common stock.

The conversion of some or all of the notes, the Green Convertible Notes or the Series B Convertible Perpetual Preferred Stock, par value $0.001 per share (the “Series B Convertible Preferred Stock”) issued to certain investors pursuant to binding subscription agreements entered into on June 16, 2025 may dilute the ownership interests of our stockholders. Upon conversion of the notes or the Green Convertible Notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to settle our conversion obligation in shares of our common stock or a combination of cash and shares of our common stock with respect to conversions of the notes or the Green Convertible Notes, any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the notes or the Green Convertible Notes may encourage short selling by market participants because the conversion of the notes or the Green Convertible Notes could be used to satisfy short positions, or anticipated conversion of the notes or the Green Convertible Notes into shares of our common stock could depress the price of our common stock. Holders of Series B Convertible Preferred Stock may elect to convert such shares into common stock at any time.

In addition, the shares of common stock to be issued in the Concurrent Stock Offering will dilute the ownership interests of our stockholders. Because the price per share of our common stock being offered in the Concurrent Stock Offering may be higher than the book value per share of our common stock, our stockholders may suffer immediate and substantial dilution in the net tangible book value of the common stock.

The accounting method for the notes and the Green Convertible Notes could adversely affect our reported financial condition and results.

The accounting method for reflecting the notes and the Green Convertible Notes on our consolidated balance sheet, accruing interest expense for the notes and the Green Convertible Notes and reflecting the underlying shares of our common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition.

In August 2020, the Financial Accounting Standards Board published Accounting Standards Update (“ASU”) 2020-06 (“ASU 2020-06”), which simplified certain of the accounting standards that apply to convertible notes.

In accordance with ASU 2020-06 and subject to our full accounting assessment with respect to the notes, which is not complete as of the date of this prospectus supplement, we expect that the notes we are offering hereunder will be, consistent with the Green Convertible Notes, reflected as a liability on our consolidated balance sheet, with the initial carrying amount equal to the principal amount of the notes, net of issuance costs. Issuance costs are treated as a debt discount for accounting purposes, which are amortized into interest expense over the term of such notes. As a result of this amortization, the interest expense that we expect to recognize for the notes for accounting purposes will be greater than the cash interest payments we will pay on the notes, which will result in lower reported net income or larger reported net loss.

S-14

In addition, consistent with the Green Convertible Notes, we expect that the shares of common stock underlying the notes will be reflected in our diluted earnings per share using the “if converted” method, in accordance with ASU 2020-06, for fiscal periods in which we report net income. Under that method, diluted earnings per share would generally be calculated assuming that all the notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. The application of the if-converted method may reduce our reported diluted earnings per share to the extent we are profitable in the future.

We cannot be sure whether other changes may be made to the current accounting standards related to the notes or the Green Convertible Notes, or otherwise, that could have a material effect on our reported financial results. We have not reached a final determination regarding the accounting treatment for the notes, and the description above is preliminary. In addition, accounting standards may change in the future. Accordingly, we may account for the notes in a manner that is significantly different than described above.

The Concurrent Stock Offering, as well as other future sales of our common stock or equity-linked securities in the public market could lower the market price for our common stock and adversely impact the trading price of the notes.

In addition, in the future, we may sell additional shares of our common stock or equity-linked securities to raise capital. In addition, a substantial number of shares of our common stock are reserved for issuance upon the exercise of stock options and upon conversion of the notes, the Green Convertible Notes and the Series B Convertible Preferred Stock. We cannot predict the size of future issuances or the effect, if any, that the Concurrent Stock Offering or future issuances may have on the market price for our common stock. The issuance and sale of substantial amounts of our common stock or equity-linked securities, or the perception that such issuances and sales may occur, could adversely affect the trading price of the notes and the market price of our common stock and impair our ability to raise capital through the sale of additional equity or equity-linked securities.

The sale of the shares of common stock offered in the Concurrent Stock Offering, the sale of the notes convertible into shares of common stock offered by this prospectus supplement and the conversion of the notes for shares of common stock, or the perception that such sales or conversions may occur, could result in a significant decline in the price of our common stock.

Concurrently with this offering, we are offering 17,570,200 shares (or up to 19,854,000 shares of our common stock if the underwriters in the Concurrent Stock Offering exercise their option to purchase additional shares in full) at a price of $8.21 per share of our common stock pursuant to a separate prospectus supplement. If all of the shares of common stock offered in the Concurrent Stock Offering and issuable upon conversion of the notes offered by this prospectus supplement were issued and outstanding, they would represent a significant percentage of our public float and of our outstanding shares of common stock. As of March 31, 2026, and after giving effect to this offering and the Concurrent Stock Offering (but without giving effect to the use of proceeds therefrom, including any Note Repurchase Transactions), the shares of common stock offered in the Concurrent Stock Offering and issuable upon conversion of the notes offered by this prospectus supplement would represent approximately 22.2% of the total number of outstanding shares of common stock (excluding (i) 5,634,313 shares of common stock issuable upon the settlement of outstanding restricted stock units (“RSUs”) and performance-based restricted stock awards (“PSUs”) and the exercise of stock options as of March 31, 2026, (ii) 23,115,521 shares of common stock authorized and reserved for future issuance under our equity and other incentive-based plans as of March 31, 2026, (iii) 5,893,798 shares of common stock issuable upon exercise of the public warrants and private warrants (the “PCT Warrants”), (iv) 17,757,136 shares of common stock issuable upon exercise of Series A Warrants, (v) 3,064,081 shares of common stock issuable upon exercise of Series B Warrants, (vi)

S-15

5,000,000 shares of common stock issuable upon exercise of Series C Warrants, (vii) 22,583,963 shares of common stock issuable upon conversion of Series B Convertible Preferred Stock and (viii) 23,237,440 shares of common stock issuable upon conversion of the Green Convertible Notes (assuming the maximum increase to the conversion rate in connection with a “make-whole fundamental change” or a notice of redemption). Accordingly, the sale of the shares of common stock offered in the Concurrent Stock Offering, the sale of the notes convertible into shares of common stock offered by this prospectus supplement and the conversion of the notes for shares of common stock, or the perception that such sales or conversions may occur, could result in a significant decline in the public trading price of our common stock.

Holders of notes will not be entitled to any rights with respect to our common stock, but they will be subject to all changes made with respect to our common stock to the extent our conversion obligation includes shares of our common stock.

Holders of notes will not be entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock) prior to the conversion date relating to such notes (if we have elected to settle the relevant conversion by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share)) or the last trading day of the relevant observation period (if we elect to pay and deliver, as the case may be, a combination of cash and shares of our common stock in respect of the relevant conversion), but holders of notes will be subject to all changes affecting our common stock. For example, if an amendment is proposed to our amended and restated certificate of incorporation or second amended and restated bylaws requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the conversion date related to a holder’s conversion of its notes (if we have elected to settle the relevant conversion by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share)) or the last trading day of the relevant observation period (if we elect to pay and deliver, as the case may be, a combination of cash and shares of our common stock in respect of the relevant conversion), such holder will not be entitled to vote any shares underlying the notes held by such holder on the amendment, although such holder will nevertheless be subject to any changes affecting our common stock.

Upon conversion of the notes, you may receive less valuable consideration than expected because the value of our common stock may decline after you exercise your conversion right but before we settle our conversion obligation.

Under the notes, a converting holder will be exposed to fluctuations in the value of our common stock during the period from the date such holder surrenders notes for conversion until the date we settle our conversion obligation.

Upon conversion of the notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to satisfy our conversion obligation in cash or a combination of cash and shares of our common stock, the amount of consideration that you will receive upon conversion of your notes will be determined by reference to the volume-weighted average price of our common stock for each trading day in a 30 trading day observation period.

If the price of our common stock decreases during this period, the amount and/or value of consideration you receive will be adversely affected. In addition, if the market price of our common stock at the end of such period is below the average volume-weighted average price of our common stock during such period, the value of any shares of our common stock that you will receive in satisfaction of our conversion obligation will be less than the value used to determine the number of shares that you will receive.

If we elect to satisfy our conversion obligation solely in shares of our common stock upon conversion of the notes, we will be required to deliver the shares of our common stock, together with cash for any fractional share, on the second business day following the relevant conversion date (provided that, with respect to any conversion

S-16

date following the regular record date immediately preceding the maturity date where physical settlement applies to the related conversion, we will settle any such conversion on the maturity date). Accordingly, if the price of our common stock decreases during this period, the value of the shares that you receive will be adversely affected and would be less than the conversion value of the notes on the relevant conversion date.

The notes are not protected by restrictive covenants.

The indenture that will govern the notes will not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries. The indenture that will govern the notes will not contain any covenants or other provisions to afford protection to holders of the notes in the event of a fundamental change or other corporate transaction involving us except to the extent described under the captions “Description of Notes—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes,” “Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption” and “Description of Notes—Consolidation, Merger and Sale of Assets.”

The increase in the conversion rate for notes converted in connection with a make-whole fundamental change or a notice of redemption may not adequately compensate you for any lost value of your notes as a result of such transaction or redemption.

If a make-whole fundamental change occurs prior to the maturity date or if we deliver a notice of redemption, we will, under certain circumstances, increase the conversion rate by a number of additional shares of our common stock for notes converted in connection with such make-whole fundamental change or notes called (or deemed called) for redemption that are converted during the related redemption period. The increase in the conversion rate will be determined based on the date on which the make-whole fundamental change occurs or becomes effective, or the date we deliver the notice of redemption, as the case may be, and the price paid (or deemed to be paid) per share of our common stock in the make-whole fundamental change or determined with respect to the notice of redemption, as the case may be and as described below under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption.” The increase in the conversion rate for notes converted in connection with a make-whole fundamental change or notes called (or deemed called) for redemption that are converted during the related redemption period may not adequately compensate you for any lost value of your notes as a result of such transaction or redemption. Furthermore, if we call only a portion of the outstanding notes for redemption, only those notes called (or deemed called) for redemption will become convertible as a result of such call for redemption and only the conversion rate of notes converted in connection with such notice of redemption will be increased. Accordingly, notes not called (or not deemed called) for redemption will not become convertible if not otherwise convertible at such time and will remain outstanding, and may have reduced liquidity and a resulting reduced trading price. In addition, if the “stock price” (as defined under the caption “Description of Notes—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption”) is greater than $40.00 per share or less than $8.21 per share (in each case, subject to adjustment), no additional shares will be added to the conversion rate. Moreover, in no event will the conversion rate per $1,000 principal amount of notes as a result of this adjustment exceed 121.8026 shares of our common stock, subject to adjustment in the same manner as the conversion rate as set forth under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments.”

Our obligation to increase the conversion rate for notes converted in connection with a make-whole fundamental change or notes called (or deemed called) for redemption that are converted during the related redemption period could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

S-17

The conversion rate of the notes may not be adjusted for all dilutive events.

The conversion rate of the notes is subject to adjustment for certain events, including, but not limited to, the issuance of certain stock dividends on our common stock, the issuance of certain rights or warrants, subdivisions, combinations, distributions of capital stock, indebtedness, or assets, cash dividends and certain issuer tender or exchange offers as described under the caption “Description of Notes—Conversion Rights—Conversion Rate Adjustments.” However, the conversion rate will not be adjusted for other events, such as a third-party tender or exchange offer or an issuance of common stock for cash, that may adversely affect the trading price of the notes or our common stock. An event that adversely affects the value of the notes may occur, and that event may not result in an adjustment to the conversion rate.

Some significant restructuring transactions may not constitute a fundamental change, in which case we would not be obligated to offer to repurchase the notes.

Upon the occurrence of a fundamental change (as described under the caption titled “Description of Notes—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes”), you have the right to require us to repurchase all or any portion of your notes. However, the fundamental change provisions will not afford protection to holders of notes in the event of other transactions that could adversely affect the notes. For example, transactions such as leveraged recapitalizations, refinancings, restructurings, or acquisitions initiated by us may not constitute a fundamental change requiring us to offer to repurchase the notes. In the event of any such transaction, the holders would not have the right to require us to repurchase the notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of notes. Furthermore, holders would not have the right to require us to repurchase the notes in circumstances involving solely a significant change in the composition of our board. See the caption “Description of Notes—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes.”

Certain provisions in the indentures governing the notes and the Green Convertible Notes may delay or prevent an otherwise beneficial takeover attempt of us.

Certain provisions in the indenture that will govern the notes may make it more difficult or expensive for a third party to acquire us. For example, the indenture that will govern the notes will require us, except as described in this prospectus supplement, to repurchase the notes for cash upon the occurrence of a fundamental change and, in certain circumstances, to increase the conversion rate for a holder that converts its notes in connection with a make-whole fundamental change. A takeover of us may trigger the requirement that we repurchase the notes and/or increase the conversion rate, which could make it costlier for a potential acquirer to engage in such takeover. Such additional costs may have the effect of delaying or preventing a takeover of us that would otherwise be beneficial to investors. The indenture governing the Green Convertible Notes contains similar provisions.

We cannot assure you that an active or liquid trading market will develop for the notes.

The notes are a new issue of securities for which there is currently no public market, and no active trading market (public or otherwise) might ever develop. If the notes are traded after their initial issuance, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, the price, and volatility in the price, of our common stock, our performance and other factors. We do not intend to apply to list the notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. We have been informed by certain of the underwriters that they intend to make a market in the notes after the offering is completed. However, such underwriters may cease their market-making at any time without notice. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result,

S-18

we cannot assure you that an active trading market will develop for the notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected. In that case you may not be able to sell your notes at a particular time or you may not be able to sell your notes at a favorable price or at all.

Any adverse rating of the notes may cause their trading price to fall.

We do not intend to seek a rating on the notes. However, if a rating service were to rate the notes and if such rating service were to lower its rating on the notes below the rating initially assigned to the notes or otherwise announces its intention to put the notes on credit watch, the trading price of the notes could decline.

You may be subject to tax if we make or fail to make certain adjustments to the conversion rate of the notes even though you do not receive a corresponding cash distribution.

The conversion rate of the notes is subject to adjustment in certain circumstances, including the payment of cash dividends. If the conversion rate is adjusted as a result of a distribution that is taxable to our stockholders, such as a distribution of money or other property, you generally will be deemed to have received a distribution, which may be treated as a dividend subject to U.S. federal income tax, without the receipt of any cash. In addition, a failure to adjust (or to adjust properly) the conversion rate after an event that increases your proportionate interest in us could be treated as a deemed taxable dividend to you. If a make-whole fundamental change occurs prior to the maturity date or if we deliver a notice of redemption, we will, under some circumstances, increase the conversion rate for notes converted in connection with the make-whole fundamental change or notice of redemption, as the case may be. Such increase also may be treated as a distribution subject to U.S. federal income tax as a dividend. See the caption “Material U.S. Federal Income Tax Considerations.” If you are a non-U.S. holder (as defined under the caption “Material U.S. Federal Income Tax Considerations”), any deemed dividend generally would be subject to U.S. federal withholding tax at a 30% rate, or such lower rate as may be specified by an applicable treaty, which may be withheld from or set off against subsequent payments of cash or delivery of shares of our common stock, if any, in respect of the notes (or, in some circumstances, any payments on our common stock) or sales proceeds payable to you or your other funds or assets. See the caption “Material U.S. Federal Income Tax Considerations.” The Internal Revenue Service has proposed regulations addressing the amount and timing of deemed distributions, obligations of withholding agents and filing and notice obligations of issuers, which, if adopted, could affect the U.S. federal income tax treatment of a holder of notes deemed to receive such a distribution. See the caption “Material U.S. Federal Income Tax Considerations.”

We may not be able to fully utilize our deferred tax assets.

We are subject to income and other taxes in the United States. As of December 31, 2025, we had U.S. federal net operating loss carryforwards of $800.8 million as described further in Note 12 “Income Taxes” to the consolidated financial statements accompanying our Annual Report. At that date, we also had recorded a valuation allowance of $214.6 million.

Our ability to use our U.S. net operating loss carryforwards may be limited if we experience an “ownership change” as defined in Section 382 of the Code (as defined herein). An ownership change generally occurs if certain stockholders increase their aggregate percentage ownership of a corporation’s stock by more than 50 percentage points over their lowest percentage ownership at any time during the testing period, which is generally the three-year period preceding any potential ownership change.

Although we may be able to utilize some or all of the U.S. net operating losses in the future if we have income of the appropriate character (subject to certain limitation on the amount of taxable income that can be offset by a net operating loss carryforward in a given taxable year), there is no assurance that we will be able to do so. Further, we are presently unable to record tax benefits on future losses until such time as sufficient income is generated by our operations to support the realization of the related net deferred tax asset positions. Our results of operations, financial condition and cash flows may adversely be affected in future periods by these limitations.

S-19

Because the notes will initially be issued in book-entry form, holders must rely on DTC’s procedures to receive communications relating to the notes and exercise their rights and remedies.

We will initially issue the notes in the form of one or more global notes registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in global notes will be shown on, and transfers of global notes will be effected only through, the records maintained by DTC. Except in limited circumstances, we will not issue certificated notes. See the caption “Description of Notes—Book-Entry, Settlement and Clearance.” Accordingly, if you own a beneficial interest in a global note, then you will not be considered an owner or holder of the notes. Instead, DTC or its nominee will be the sole holder of global notes. Unlike persons who have certificated notes registered in their names, owners of beneficial interests in global notes will not have the direct right to act on our solicitations for consents or requests for waivers or other actions from holders. Instead, those beneficial owners will be permitted to act only to the extent that they have received appropriate proxies to do so from DTC or, if applicable, a DTC participant. The applicable procedures for the granting of these proxies may not be sufficient to enable owners of beneficial interests in global notes to vote on any requested actions on a timely basis. In addition, notices and other communications relating to the notes will be sent to DTC. We expect DTC to forward any such communications to DTC participants, which in turn would forward such communications to indirect DTC participants. However, we can make no assurances that you will timely receive any such communications.

Any repurchases of the Green Convertible Notes may affect the value of the notes and our common stock.

We expect to use a portion of the net proceeds from this offering and the Concurrent Stock Offering, if consummated, to repurchase for cash approximately $216.0 million in aggregate principal amount at maturity of the Green Convertible Notes, including $50.0 million in aggregate principal amount at maturity of the Green Convertible Notes held by the affiliated investors, for cash in the Note Repurchase Transactions. No assurance can be given as to how much, if any, of the Green Convertible Notes will be repurchased or the terms on which they will be repurchased. This prospectus supplement is not an offer to repurchase the Green Convertible Notes, and the offering of the notes is not contingent upon the Note Repurchase Transactions.

In connection with any Note Repurchase Transaction, we expect that the hedged holders will unwind all or part of their hedge positions by buying shares of our common stock, including pursuant to the Concurrent Stock Offering, and/or entering into or unwinding various derivative transactions with respect to our common stock. The amount of our common stock to be purchased by the hedged holders or in connection with such derivative transactions may be substantial in relation to the historic average daily trading volume of our common stock. This activity by the hedged holders could increase (or reduce the size of any decrease in) the market price of our common stock, including concurrently with the pricing of the notes, which could result in a higher effective conversion price for the notes. We cannot predict the magnitude of such market activity or the overall effect it will have on the price of the notes offered hereby or our common stock.

This offering is not contingent on the consummation of the Concurrent Stock Offering, and vice versa, or the Note Repurchase Transactions.

Neither the completion of this offering nor the Concurrent Stock Offering is contingent on the completion of the other or the Note Repurchase Transactions. No assurance can be given that the Concurrent Stock Offering will be completed on the terms described herein or at all. This prospectus supplement does not constitute an offer to sell, or the solicitation of an offer to buy, any shares of our common stock in the Concurrent Stock Offering. See the caption “The Concurrent Transactions.”

Risks Related to Our Common Stock

Certain of our current and former stockholders have the right to elect a certain number of directors to our board of directors.

Pursuant to a letter agreement entered into between Pure Crown LLC (“Pure Crown”) and PCT, dated October 5, 2020, Pure Crown is entitled to select one director (the “Pure Crown Director”) to our Board of Directors (the “Board”), and Pure Crown designated Ms. Tanya Burnell as the current Pure Crown Director. For so long as Pure Crown has this right to select one director to the Board, any vacancy with respect to the Pure Crown Director may only be filled by Pure Crown.

Furthermore, pursuant to the board representation agreement, dated March 7, 2022 (the “Board Representation Agreement”), between PCT and Sylebra Capital, Sylebra Capital has been granted the right to designate (i) one person to be nominated for election to the Board so long as Sylebra Capital together with its affiliates beneficially owns at least 10.0% of the common stock, and (ii) two persons to be nominated for election to the Board so long as Sylebra Capital together with its affiliates beneficially owns at least 15.0% of the common stock, subject to certain exceptions, including that Sylebra Capital together with its affiliates will not be entitled to designate more than two nominees. Accordingly, Sylebra Capital is currently entitled to designate two directors for nomination, and has designated Valerie Mars and Dan Gibson to serve on the Board.

Future offerings of debt or offerings or issuances of equity securities by us may adversely affect the market price of our common stock or otherwise dilute all other stockholders.

In the future, we may attempt to obtain financing or further increase our capital resources by issuing additional shares of our common stock or offering debt, including commercial paper, medium-term notes, senior or subordinated notes, debt securities convertible into equity or shares of preferred stock. We also expect to grant equity awards to employees, directors, and consultants under our stock incentive plans.

The implementation of our business strategy could require substantial additional capital in excess of cash generated from operations. We would expect to obtain the capital required for the implementation of our business strategy through a combination of additional issuances of equity, corporate indebtedness and/or cash from operations, which may be effectuated through private financings.

Issuing additional shares of our common stock or other equity securities or securities convertible into equity may dilute the economic and voting rights of our existing stockholders or reduce the market price of our common stock or both, and could be constrained by stock exchange rules that may require prior stockholder approval for certain large or below market issuances. Upon liquidation, holders of such debt securities and preferred shares, if issued, and lenders with respect to other borrowings would receive a distribution of our available assets prior to the holders of our common stock. Preferred shares, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of our common stock. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing and nature of our future offerings.

Sales of a substantial number of shares of our common stock, or the perception that such sales may occur, may impair our future ability to raise capital.

Sales of a substantial number of shares of our common stock in the public markets could impair our ability to raise capital through the sale of additional equity securities or securities convertible into equity shares in the future.

The price of our common stock may be volatile.

The market price of our common stock may fluctuate substantially. For example, from January 1, 2025 through June 9, 2026, the closing price of our common stock fluctuated between $5.11 and $16.92. The

S-21

price of our common stock that will prevail in the market after this offering may be higher or lower than the price that you have paid, depending on many factors, some of which are beyond our control and may not be related to our operating performance. Stock market volatility may also adversely affect the trading price of our common stock. In the past, following periods of volatility in the market price of a company’s securities, stockholders have often instituted class action securities litigation against those companies. Such litigation, if instituted, could result in substantial costs and diversion of management attention and resources, which could significantly harm our profitability and reputation.

Future sales of shares of the common stock by existing stockholders may depress its stock price.

In connection with the closing of the business combination (“Business Combination”) by and among Roth CH Acquisition I Co., a Delaware corporation (“ROCH”), Roth CH Acquisition I Co. Parent Corp., a Delaware corporation and wholly-owned direct subsidiary of ROCH (“ParentCo”), Roth CH Merger Sub LLC, a Delaware limited liability company and wholly-owned direct subsidiary of Parent Co, Roth CH Merger Sub Corp., a Delaware corporation and wholly-owned direct subsidiary of ParentCo and PureCycle Technologies LLC, a Delaware limited liability company and indirect wholly-owned subsidiary of PCT (“PCT LLC”), holders of the Class A Units, Class B preferred Units, Class B-1 preferred Units and Class C Units of PCT LLC (collectively, the “PCT Unitholders”) representing at least 70% of PCT LLC’s outstanding membership interests entered into the Investor Rights Agreement, whereby such PCT Unitholders agreed, with certain limited exceptions, to lock up the shares of the common stock they received in the Business Combination (the “IRA Lock-up”). On March 17, 2026, the IRA Lock-up expired pursuant to its terms, and the PCT Unitholders are able to sell the final 33.33% of such PCT Unitholder’s shares of the common stock (or 50% of such PCT Unitholder’s shares of the common stock with respect to certain affiliates of PCT LLC at the time of the Business Combination).

Following the expiration of the IRA Lock-up, the PCT Unitholders are no longer restricted from selling their shares of the common stock, other than by applicable securities laws. The timing or volume of sales or possible sales of these shares could have the effect of increasing the volatility in PCT’s share price or the market price of the shares of common stock could decline if a large amount of the shares of common stock are sold by the PCT Unitholders or if a large amount of the PCT Unitholders are perceived by the market as intending to sell the shares of common stock held by them. These sales, or the possibility that these sales could occur, may make it more difficult for the Company or its stockholders to sell equity securities in the future at a time and at a price that the Company or its stockholders deem appropriate.

PCT’s revenues, results of operations and cash utilization may fluctuate significantly from period to period.

As PCT advances its commercial operations, its revenues, results of operations and/or cash utilization may be subject to significant quarterly fluctuations. This variability can result from a number of factors that are difficult to predict and that are in many cases outside of PCT’s control, including: customer qualification and sales cycle timing; order and shipment timing, which may be impacted by production schedules, logistics constraints, and customer-specific arrangements; production and operation constraints, due to mechanical challenges or otherwise; and fixed cost structure relative to variable revenues. As a consequence of these factors, PCT’s revenues, operating results, and cash flows may vary materially from quarter to quarter. Such variability could make it difficult for PCT to accurately forecast its revenues, meet financial obligations as they become due, and maintain compliance with financial covenants under its debt agreements, and could adversely affect PCT’s business, financial condition, results of operations and prospects.

In addition, as PCT continues to ramp production at its first commercial-scale recycling facility in Lawrence County, Ohio (the “Ironton Facility”) and expand commercial shipments to customers over the coming periods, PCT operating results and cash utilization could differ materially from analysts’ and/or investors’ expectations. The Company believes the trading market for the common stock may be influenced by the research and reports that industry or securities analysts publish about PCT. If one or more of the analysts who cover PCT downgrade the common stock or publish unfavorable research, or if PCT operating results or cash utilization do not meet their or investors’ expectations, PCT’s stock price could decline.

S-22

Risks Related to PCT’s Status as a Low-Revenue Early Commercial-Stage Company

PCT is a low-revenue early commercial-stage company that has incurred operating losses since inception, and expects to continue to incur operating losses and PCT may never achieve or sustain operating profitability, which depends on the successful commercialization and scale-up of PureFive^® resin products, and any other products PCT may develop in the future, to scale in the U.S., Europe, Asia and other territories.

PCT has incurred operating losses since inception, and expects to continue to incur operating losses as it continues to commercialize and scale up its PureFive^® resin products. PCT relies principally on the commercialization of its PureFive^® resin, and any other products PCT may develop in the future, to generate revenue growth. This includes establishing sales, marketing and distribution capabilities to effectively market and sell PureFive^® resin products in the U.S., Europe, Asia, and in other territories; expanding the number of Purification plants and Feed PreP facilities; and maintaining and growing relationships with offtake partners, feedstock suppliers, customers, and other strategic partners. Achieving these objectives also requires procuring and maintaining all required regulatory approvals.

Market uncertainties, particularly related to demand for PureFive^® resin, and any other products PCT may develop in the future, pricing dynamics and feedstock costs, make it difficult to predict the timing or amount of increased expenses or the timing, if ever, of achieving profitability. If demand for PureFive^® resin products does not grow as anticipated, or if PCT cannot secure sufficient feedstock, offtake commitments or favorable pricing, revenue levels may not increase as expected. Even if adoption improves, adverse market conditions, cost pressures or execution risks may prevent PCT from generating sufficient revenue to achieve or sustain profitability. PCT currently has no other material lines of business or sources of revenue beyond PureFive^® resin products, and this lack of diversification may limit its ability to adapt to changing business conditions and could adversely affect its business, financial condition, results of operations and prospects.

PCT’s operations are substantially dependent on intellectual property licensed from P&G under the License Agreement, and any termination, conversion or impairment of such license could have a material adverse effect on PCT’s business.

PCT’s operations are substantially dependent on the continued validity and enforceability of the intellectual property licensed from P&G under the License Agreement. Pursuant to the License Agreement, P&G has granted PCT a license to utilize certain P&G intellectual property. The License Agreement sets forth certain construction and sales deadlines for future facilities outside North America, which, if missed, could result in (i) a termination of the license granted under the License Agreement (if PCT is unable to make PureFive^® resin at certain production volumes and at certain prices within a certain time frame) or (ii) conversion of the license to a non-exclusive license (if PCT is unable or unwilling to provide P&G with PureFive^® resin at certain prices from the first plant). In the event the License Agreement is terminated or converted to a non-exclusive license, this could have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

If the P&G license is converted to a non-exclusive license following a failure to comply with the terms of the License Agreement, PCT could face competition in the future from new market entrants or existing competitors expanding their business. If the License Agreement is terminated, PCT would not have the right to utilize the P&G intellectual property that underpins the Technology, and the production of PureFive^® resin, and PCT’s business, would not be viable unless PCT is able to develop an alternative technology. PCT has limited ability to control the prosecution, maintenance or enforcement of the underlying P&G intellectual property, and P&G may make decisions regarding such intellectual property that are adverse to PCT’s interests. Any improvements to the licensed technology developed by PCT may be subject to ownership or licensing provisions that limit PCT’s ability to exploit such improvements independently. In addition, PCT’s compliance with the terms of the License Agreement, including sublicensing limitations, quality standards and reporting obligations, is an ongoing obligation, and any breach, whether actual or alleged, could give rise to a termination right or other remedies in favor of P&G. PCT’s dependence on third-party-owned technology means that any challenge to, or

S-23

invalidation of, the underlying P&G intellectual property could materially impair PCT’s competitive position and its ability to operate its business, and could have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

PCT’s substantial indebtedness, restrictive covenants, and potential inability to obtain additional financing could materially and adversely affect its business, financial condition, results of operations and prospects.

As of March 31, 2026, PCT had total consolidated indebtedness of $403.8 million, including bonds payable to related parties and does not yet have any sources of material recurring revenue. PCT’s existing and future debt service obligations, together with restrictions in its financing arrangements and the uncertainty of access to additional capital, could have important consequences for the foreseeable future. A significant portion of cash flow from operating activities, if and when generated, will be required to service debt, which will reduce funds available for operations, capital expenditures, strategic initiatives, and other corporate purposes. PCT’s leverage may exceed that of some competitors, potentially placing it at a competitive disadvantage and increasing its vulnerability to market conditions, operational challenges, and changes in law or regulations. In addition, PCT’s ability to obtain additional financing for capital expenditures, and other needs may be impaired by its existing debt and related covenants, as well as by general market conditions.

PCT’s debt agreements, including the Loan Agreement (as defined below), and certain other agreements to which PCT is a party, contain operating, financial covenants and other restrictions that, among other things, limit PCT and its subsidiaries’ ability to incur additional debt, certain liens or other encumbrances, sell assets, transfer ownership interests, pay dividends, and enter into transactions with affiliates. These limitations could restrict activities that may be in PCT’s long-term interests and reduce its financial and operational flexibility. PCT has in the past obtained waivers or amendments for non-compliance with financial covenants; however, a failure to comply with covenants or obtain a waiver in the future could result in an event of default under one or more agreements, permitting lenders to accelerate maturity, foreclose on collateral securing the debt, terminate commitments, or exercise other remedies. Cross-default provisions could compound these effects, and PCT might not have sufficient funds or resources to satisfy its obligations or to refinance or restructure such indebtedness on favorable terms or at all.

Additionally, PCT’s estimate of its operating expenses and capital expenditures requirements is based on assumptions that may prove to be wrong, and PCT could use its available capital resources sooner than it currently expects. Changing circumstances, some of which may be beyond PCT’s control, could cause PCT to consume capital significantly faster than it currently anticipates, and PCT may need to seek additional funds sooner than planned.

Until PCT can generate significant revenue from sales of its products, PCT will require additional financing to fund its operations and growth. There can be no assurance that additional capital will be available when needed, on acceptable terms or at all. Any such financing, if available, may involve the issuance of equity or equity-linked securities that are dilutive to existing stockholders, securities with preferences that are senior to the common stock, or additional indebtedness that imposes restrictive covenants, collateral requirements, or repayment obligations, each of which could further constrain PCT’s operations and liquidity. PCT may also seek capital opportunistically due to favorable market conditions or strategic considerations even if it believes existing resources are adequate. If PCT cannot obtain financing when required or on reasonable terms, it may be unable to execute its business strategy, meet obligations as they come due, or maintain compliance with financial covenants, any of which would adversely affect its business, financial condition, results of operations and prospects.

PCT faces risks and uncertainties related to litigation, regulatory actions and investigations.

From time to time, PCT has and may continue to be involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, product liability, relationships

S-24

with our feedstock suppliers and offtake partners as well as strategic partners, intellectual property disputes, additional volatility in the market price of our securities and other business matters. Any such claims or investigations may be time-consuming, costly, divert management resources, or otherwise have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

The results of litigation and other legal proceedings are inherently uncertain and adverse judgments or settlements may result in materially adverse monetary damages or injunctive relief against PCT. Any claims or litigation, even if fully indemnified or insured, could damage PCT’s reputation and make it more difficult to compete effectively or obtain adequate insurance in the future. The litigation and other legal and regulatory proceedings described in the notes to PCT’s audited consolidated financial statements included in its Annual Report are subject to future developments and management’s view of these matters may change in the future.

Risks Related to PCT’s Operations

If PCT is unable to consistently execute capital investment projects to cost and schedule, and to achieve and sustain targeted production volumes, yields, uptime, quality and economics at the Ironton Facility, the Company’s economic viability and ability to raise capital could be materially and adversely impacted, and construction of one or more additional PreP and Purification facilities may be delayed or abandoned.

The Ironton Facility is the foundation of PCT’s commercial strategy. Failure to increase production rates that approach the plant’s full capacity and can meet expected current and future customer demand, as well as maintain sufficient uptime, product quality specifications and unit economics at the Ironton Facility could undermine investor confidence and PCT’s ability to attract future capital, customers and strategic partners as it continues development of the other Planned Facilities. Operational challenges at the Ironton Facility have included, but are not limited to: (i) filter fouling, including the accumulation of contaminants on filtration systems that can reduce throughput, increase maintenance requirements and cause unplanned downtime; (ii) co-product handling, including the potential monetization of non-polypropylene materials and process residues; (iii) odor and color specification compliance, which are among the most difficult quality parameters to achieve consistently at commercial scale; and (iv) maintenance downtime, including both planned and unplanned outages that reduce effective operating hours and output. Any one or more of these operational challenges or failures, individually or in combination, could prevent PCT from achieving or sustaining the production volumes, yields, uptime, quality or economics required to demonstrate commercial viability, satisfy offtake commitments and support the construction and financing of future Planned Facilities.

Additionally, the construction and commissioning of any new project, including PreP and Purification facilities, is dependent on a number of contingencies, many of which are beyond PCT’s control. There is also a risk that significant unanticipated costs or delays could arise due to, among other things, errors or omissions, unanticipated or concealed construction site conditions, including subsurface conditions, unforeseen technical issues or increases in plant and equipment costs, delays in delivery of certain long-lead items, insufficiency of water supply and other utility infrastructure, inadequate contractual arrangements or unanticipated or unforeseen regulatory requirements, engineering, procurement, and construction contract delays or defaults, cost overruns arising from changes in scope, labor or materials pricing, permitting delays or denials, and the inability to replicate at future facilities the operational learnings and process improvements achieved at the Ironton Facility. Should significant unanticipated costs arise, this could have a material adverse impact on PCT’s business, financial performance, cash utilization and operations. No assurance can be given that construction will commence or be completed, or will be completed without further delay.

Delays in commissioning and obtaining an independent engineer’s certificate of operational performance at the Ironton Facility or any new project could severely impact PCT’s business, financial condition, results of operations and prospects.

PCT may not be able to achieve full commissioning and the certification of operational performance required by an independent engineer of the Ironton Facility due to a variety of factors including, but not limited

S-25

to, the rates at which other plastics and additives can currently be removed from the Purification process, as well as challenges with sustaining continuous operations at full capacity over a number of consecutive days. Failure to achieve full commissioning, obtain the certification or sustain continuous operations at the Ironton Facility could severely impact PCT’s business, financial condition, results of operations and prospects, and impact PCT’s ability to comply with certain covenants under its debt agreements.

PCT currently relies on a single facility for all of its operations, and its business is not diversified.

PCT currently relies solely on the operations at the Ironton Facility, and there is no guarantee that the Planned Facilities will be constructed on the expected timeline, or at all. Adverse changes or developments affecting the Ironton Facility could impair PCT’s ability to produce PureFive^® resin and impact its business, prospects, financial condition and results of operations. Any shutdown or period of reduced production at the Ironton Facility, which may be caused by regulatory noncompliance or other issues, as well as other factors beyond its control, such as severe weather conditions, natural disaster, fire, power interruption or outages, work stoppage, disease outbreaks or pandemics, equipment failure, delay in supply delivery, or shortages of material, equipment, or labor, has in the past, and would in the future, significantly disrupt PCT’s ability to grow and produce PureFive^® resin products in a timely manner, or at all, meet its contractual obligations and operate its business. PCT has historically experienced periodic equipment failures, some of which have caused extended interruptions to plant operations, and other interruptions or plant shutdowns could occur in the future. Some of PCT’s equipment is costly to repair, and PCT’s equipment supply chains may be disrupted in connection with pandemics, trade wars or other factors. If any material amount of PCT’s machinery were damaged, it would be unable to predict when, if at all, it could replace or repair such machinery or find co-manufacturers with suitable alternative machinery, which could adversely affect PCT’s business, financial condition, results of operations and prospects. Performance guarantees may not be sufficient to cover damages or losses, or the guarantors under such guarantees may not have the ability to pay. Any insurance coverage PCT has may not be sufficient to cover all of its potential losses and may not continue to be available to PCT on acceptable terms, or at all.

There are also currently no other lines of business or other material sources of revenue to support the Company’s future. Such lack of diversification may limit PCT’s ability to adapt to changing business conditions and could have an adverse effect on PCT’s business, financial condition, results of operations and prospects.

Cybersecurity incidents and the failure to maintain the integrity of PCT’s systems or infrastructure, or those of third parties with which PCT does business, could have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

PCT is subject to an increasing number of information technology vulnerabilities, threats and targeted computer crimes that pose a risk to the security of its systems and networks and the confidentiality, availability and integrity of data. Disruptions or failures in the physical infrastructure or operating systems that support PCT’s businesses, offtake partners, feedstock suppliers and customers, or cyber-attacks or security breaches of PCT’s networks or systems or of third party suppliers and service providers, could result in the loss of customers and business opportunities, lawsuits, regulatory fines, penalties or intervention, reputational damage, loss of stakeholder confidence, reimbursement or other compensatory costs, and additional compliance costs, any of which could materially adversely affect PCT’s business, financial condition, results of operations and prospects. In addition, recently enhanced cybersecurity disclosure requirements increase the risk of regulatory scrutiny enforcement actions and securities litigation in the wake of a material cyber incident. Emerging artificial intelligence (“AI”) technologies may intensify these cybersecurity risks and introduce new governance and compliance obligations under evolving AI-related laws and guidance in the U.S. and abroad. In addition, PCT relies on third party software-as-a service and cloud providers for critical business functions, and any disruptions, misconfiguration or breach in these services could materially impact the Company’s business. Increasing costs associated with cybersecurity protections may be costly and may also adversely affect the financial condition of PCT. While PCT attempts to mitigate these risks, PCT’s systems, data, networks, products, solutions and services remain potentially vulnerable to advanced and persistent cybersecurity threats.

S-26

PCT also maintains and has access to sensitive, confidential or personal data or information in its business that is subject to privacy and security laws, regulations and customer controls. Despite PCT’s efforts to protect such personal data or information, PCT’s facilities and systems and those of its customers, offtake partners, feedstock suppliers and third-party service providers may be vulnerable to cybersecurity incidents, theft, misplaced or loss of data, insider threats, supply chain risks, natural disasters, zero-day vulnerabilities, programming and/or human errors that could lead to the compromise of sensitive, confidential or personal data or information or unauthorized use or disruption of PCT’s systems and software.

PCT may be unable to sufficiently protect its proprietary rights and may encounter disputes from time to time relating to its use of the intellectual property of third parties.

PCT relies on its proprietary intellectual property, including registered trademarks and certain licensed intellectual property under the License Agreement and other documents to market, promote and sell PureFive^® resin products. PCT monitors and protects against activities that might infringe, dilute, or otherwise harm its trademarks and other intellectual property and relies on the relevant patent, trademark and other laws of the U.S. and other countries. However, PCT may be unable to prevent third parties from using its intellectual property without authorization. In addition, the laws of some non-U.S. jurisdictions, particularly those of certain emerging markets, provide less protection for PCT’s proprietary rights than the laws of the U.S. and present greater risks of counterfeiting and other infringement. To the extent PCT cannot protect its intellectual property, unauthorized use and misuse of PCT’s intellectual property could harm its competitive position and have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

Despite PCT’s efforts to protect these rights, unauthorized third parties may attempt to duplicate or copy the proprietary aspects of its technology and processes. PCT’s competitors and other third parties independently may design around or develop similar technology or otherwise duplicate PCT’s services or products such that PCT could not assert its intellectual property rights against them. In addition, PCT’s contractual arrangements may not effectively prevent disclosure of its intellectual property and confidential and proprietary information or provide an adequate remedy in the event of an unauthorized disclosure. Measures in place may not prevent misappropriation or infringement of PCT’s intellectual property or proprietary information and the resulting loss of competitive advantage, and PCT may be required to litigate to protect its intellectual property and proprietary information from misappropriation or infringement by others, which is time consuming, expensive, could cause a diversion of resources and may not be successful.

PCT also may encounter disputes from time to time concerning intellectual property rights of others, and it may not prevail in these disputes. Third parties may raise claims against PCT alleging that PCT, or consultants or other third parties retained or indemnified by PCT, infringe on their intellectual property rights. Some third-party intellectual property rights may be extremely broad, and it may not be possible for PCT to conduct its operations in such a way as to avoid all alleged violations of such intellectual property rights. Given the complex, rapidly changing and competitive technological and business environment in which PCT operates, and the potential risks and uncertainties of intellectual property-related litigation, an assertion of an infringement claim against PCT may cause PCT to spend significant amounts to defend the claim, even if PCT ultimately prevails, pay significant money damages, lose significant revenues, be prohibited from using the relevant systems, processes, technologies or other intellectual property (temporarily or permanently), cease offering certain products or services, or incur significant license, royalty or technology development expenses.

Moreover, it has become common in recent years for individuals and groups to purchase intellectual property assets for the sole purpose of making claims of infringement and attempting to extract settlements from companies such as PCT. Even in instances where PCT believes that claims and allegations of intellectual property infringement against it are without merit, defending against such claims is time consuming and expensive and could result in the diversion of time and attention of PCT’s management and employees. In addition, although in some cases a third party may have agreed to indemnify PCT for such costs, such

S-27

indemnifying party may refuse or be unable to uphold its contractual obligations. In other cases, insurance may not cover potential claims of this type adequately or at all, and PCT may be required to pay monetary damages, which may be significant.

Climate change, or legal, regulatory or market measures to address climate change may materially adversely affect the Company’s financial condition and business operations.

Climate change resulting from increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could present risks to PCT’s future operations from natural disasters and extreme weather conditions, such as hurricanes, tornadoes, wildfires or flooding. Such extreme weather conditions could pose physical risks to PCT’s facilities and disrupt operation of PCT’s supply chain and may impact operational costs. The impacts of climate change on global resources may result in scarcity, which could in the future impact PCT’s ability to access sufficient equipment and materials in certain locations and result in increased costs.

Additionally, concern over climate change could result in new legal or regulatory requirements designed to mitigate the effects of climate change on the environment. If such laws or regulations are more stringent than current legal or regulatory requirements, PCT may experience increased compliance burdens and costs to meet the regulatory obligations and may adversely affect raw material sourcing, manufacturing operations and the distribution of PCT’s products. Likewise, a failure to comply with any current or future sustainability-related reporting requirements, as established by regulators in the U.S., Europe, and beyond, may result in loss of business, regulatory penalties, litigation, and/or reputational damage.

PCT may be negatively impacted by volatility in the political and economic environment, which could have an adverse impact on PCT’s business, financial condition, results of operations and prospects.

Trade, monetary and fiscal policies, and political and economic conditions may substantially change, and credit markets may experience periods of constriction and variability. These conditions may impact PCT’s business. Further, rising or prolonged high inflation may negatively impact PCT’s business and raise its costs, specifically with respect to the construction of the Planned Facilities and other future Purification and Feed PreP facilities. In the case of sustained inflation, it could become increasingly difficult to effectively mitigate the increases to PCT’s costs. If PCT is unable to take actions to effectively mitigate the effect of the resulting higher costs, PCT’s business, financial condition, results of operations and prospects could be adversely impacted.

Although the Federal Reserve began to reduce interest rates in late 2024 through 2025, they continue to remain higher than pre-pandemic levels. The Federal Reserve may continue to hold them at their currently high rates longer than expected. Higher interest rates, coupled with reduced government spending and volatility in financial markets, may increase economic uncertainty and affect PCT’s offtake partners, feedstock suppliers and potential customers. Similarly, the ongoing military conflict between Russia and Ukraine and the current instability in the Middle East has created volatility in various markets and could have further global economic consequences, including disruptions of the global supply chain, increased costs and energy markets. Furthermore, actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity concerns. Any such volatility, disruptions or market-wide liquidity concerns may adversely affect PCT’s business or the third parties on whom it relies. If the equity and credit markets deteriorate, including as a result of political or economic unrest or war, it may make necessary debt or equity financing, such as the financing necessary to fully fund the construction of the Planned Facilities, future Purification facilities and currently contemplated and future Feed PreP facilities and otherwise finance PCT’s expansion, more difficult to obtain in a timely manner or on favorable terms, more costly or more dilutive. Increased or sustained inflation can adversely affect PCT by increasing its costs, including labor and employee benefit costs. In addition, higher or sustained inflation, macro turmoil, uncertainty and market-wide

S-28

liquidity concerns could also adversely affect PCT’s offtake partners, feedstock suppliers and potential customers, which could have an adverse impact on PCT’s business, financial condition, results of operations and prospects.

Risks Related to PCT’s Production of PureFive^® Resin

There is no guarantee the Technology is scalable to commercial-scale profitability.

The Technology is based upon generally-available commercial equipment to process contaminated polypropylene into clean recycled polypropylene product. While PCT has constructed the Feedstock Evaluation Unit (the “FEU”) to demonstrate the process using the same or similar equipment (except at a smaller scale) as the Ironton Facility, and, for the most part, the Planned Facilities, the FEU does not operate at a commercial scale. The FEU test data was used to design the Ironton Facility equipment for commercial scale and testing under the intended operating conditions and configuration for the commercial-scale operation to verify reproducibility of results including color, melt flow index, moldability (tensile modulus and other measures) and the odor of the final PCT-produced polypropylene product. While that testing indicated that the FEU can generate recycled polypropylene product that, on average, meets all of its key parameter targets, PCT cannot guarantee these results will be achieved if or when the Ironton Facility, or any of the Planned Facilities, are operating at full capacity. PCT’s ability to achieve commercial-scale profitability relies on its ability to commercially scale its operations. Further, of the four quality parameters for PureFive^® resin, odor is the most difficult to characterize and measure. PCT’s goal is to generate product that will significantly reduce the odor of the offtake and be comparable or nearly comparable to virgin polypropylene with respect to level of odor, but PCT cannot guarantee that the Ironton Facility, or any of the Planned Facilities, will be capable of achieving the quality parameters of PureFive^® resin on a consistent basis to achieve profitability on a commercial scale. The Ironton Facility’s, or any of the Planned Facilities’, failure to consistently achieve the quality parameters for PureFive^® resin at higher rates could impact PCT’s business, financial condition, results of operations and prospects if the possible shortfalls versus specification are not effectively remedied per contract.

Furthermore, each of the Thailand Facility and PCT’s first commercial-scale European plant at its Antwerp, Belgium site (the “Belgium Facility”) are expected to be larger 130 million-pound per year Purification facilities and the Purification facility to be built in Augusta, Georgia (the “Augusta Facility” and together with the Thailand Facility and the Belgium Facility, the “Planned Facilities”) is planned to be PCT’s first scaled-up facility model, with an expected capacity of 300 million pounds per year. PCT is currently working on engineering for the Thailand Facility and Belgium Facility, and pre-engineering for the design and installation of the scaled-up Purification facility at the Augusta Facility, and there is no guarantee that these efforts will be successful. If the Thailand Facility and Belgium Facility are not completed and operational, and the Augusta Facility fails to achieve the expected efficiencies, including across the construction and permitting processes, as well as fails to reduce average capital expenditures per plant and reduce overall operating costs, PCT’s business, financial condition, results of operations and prospects could be materially adversely impacted.

PCT may not be successful in consummating strategic endeavors for the sale of PureFive^® resin products.

PCT may not be successful in efforts to establish or consummate strategic endeavors, or other alternative arrangements for the sale of PureFive^® resin products because PCT’s products may be deemed to be at too early of a stage of development for collaborative effort or third parties may not view PCT’s product as having the requisite potential to demonstrate commercial success.

If PCT is unable to reach agreements with existing or future customers on a timely basis, on acceptable terms or at all, PCT may have to curtail the development of PureFive^® resin products, reduce or delay the development program, delay potential commercialization, reduce the scope of any sales or marketing activities or increase expenditures and undertake development or commercialization activities at PCT’s own expense. If PCT

S-29

elects to fund development or commercialization activities on its own, PCT may need to obtain additional expertise and additional capital, which may not be available on acceptable terms or at all. If PCT fails to enter into collaborations and does not have sufficient funds or expertise to undertake the necessary development and commercialization activities, PCT may not be able to further develop product candidates and PCT’s business, financial condition, results of operations and prospects may be materially and adversely affected.

PCT’s failure to secure sufficient quantities of waste polypropylene could have a negative impact on PCT’s business, financial condition, results of operations and prospects.

PCT’s ability to procure a sufficient quantity and quality of post-industrial and post-consumer waste that contains high levels of polypropylene as feedstock is dependent upon certain factors outside of PCT’s control, including, but not limited to:

•

changes to pricing levels for waste polypropylene, recycled polypropylene and non-recycled polypropylene;

•

shortages in supply or reductions in available volumes due to seasonal, regional or market-driven factors;

•

logistics and transportation constraints, including the cost and availability of transportation infrastructure necessary to move feedstock from collection points to PCT’s facilities;

•

competition from other buyers of waste polypropylene, including mechanical recyclers, other advanced recyclers and virgin resin producers seeking to meet recycled-content commitments, which may reduce the volume available to PCT or increase procurement costs;

•

regional availability and collection infrastructure limitations, particularly in Asia where post-consumer polypropylene collection rates are low or collection infrastructure is underdeveloped;

•

interruptions affecting suppliers, including those due to operational restraints, industrial relations, transportation difficulties, accidents or natural disasters; and

•

the introduction of new laws or regulations that may make access to waste polypropylene more difficult or expensive.

Additionally, while PCT believes it has sourced sufficient feedstock of desirable quality and with high levels of polypropylene, and that it has the ability to increase polypropylene content at its pre-processing facilities, it cannot guarantee that feedstock suppliers will have sufficient quantities available and at the appropriate specifications in accordance with their respective agreements with PCT. If feedstock is not available to PCT in sufficient quantity and of requisite quality and with high levels of polypropylene, PCT’s business, financial condition, results of operations and prospects could be materially adversely impacted.

Because PCT’s global expansion requires sourcing feedstock and supplies and shipping product around the world (including Asia and Europe), changes to international trade agreements, tariffs, import and excise duties, taxes or other governmental rules and regulations could adversely affect PCT’s business, financial condition, results of operations and prospects.

PCT’s global expansion model, which includes the construction of the Planned Facilities, will require sourcing additional feedstock in the U.S. and from suppliers around the world. The U.S. federal government, the Belgian government, the Thai government and other governmental bodies may propose changes to international trade agreements, tariffs, taxes and other government rules and regulations that would affect PCT’s global expansion model. For example, the U.S. government has imposed and expanded tariffs and other trade measures on certain foreign imports into the U.S., particularly from China, Canada, and Mexico. If any restrictions or significant increases in costs or tariffs are imposed related to feedstock sourced from Asia, Europe, or elsewhere, as a result of amendments to existing trade agreements, and PCT’s supply costs consequently increase, PCT may

S-30

be required to raise PureFive^® resin product prices, which may result in decreased margins, the loss of customers, and a material adverse effect on PCT’s financial results. The extent to which PCT’s margins could decrease in response to any future tariffs is uncertain. PCT continues to evaluate the impact of effective trade agreements, as well as other recent changes in foreign trade policy on its supply chain, costs, sales and profitability, which could negatively impact PCT’s business, financial condition, results of operations and prospects. Any such impact could be material.

There is no guarantee the Feed PreP facilities will be viable or achieve the expected efficiencies.

In conjunction with future Purification facilities, PCT expects to build and operate Feed PreP facilities in locations geographically near the feed sources in an effort to optimize PCT’s supply chain economics. These Feed PreP facilities are expected to employ feedstock processing systems with advanced sorting capabilities that can handle various types of plastics in addition to polypropylene (designated as no. 5 plastic), such as plastic bales between #1 and #7. There is no guarantee that the Feed PreP facilities will be successful. If the feedstock processing systems don’t operate as expected, or in a commercially viable manner or are constrained from receiving permits necessary to operate the facilities by city, country or state regulations; the Feed PreP facilities fail to achieve the expected efficiencies, including due to increased shipping costs; as well as fail to reduce average expenditures on feedstock and reduce overall operating costs, PCT’s business, financial condition, results of operations, and prospects could be materially adversely impacted.

There is no guarantee the “Feedstock+” pricing model will be successful or adopted broadly across PCT’s offtake agreements. For those agreements where selling prices remain linked to virgin polypropylene price indices, PCT’s feedstock, PreP, energy, logistics and plant costs may not move commensurately, which may result in margin compression or elimination in low oil price environments.

PCT’s Feedstock+ pricing model for offtake agreements uses a formula based on: (i) a secondary materials per pound pricing index for curbside bales divided by a fixed polypropylene yield loss modifier, plus (ii) a fixed base price per pound covering PCT’s operating and conversion costs. The Feedstock+ pricing model is designed to mitigate the impact on PCT’s operating margins by incorporating the feedstock market price fluctuations, upside and downside, into the PureFive^® price. There is no guarantee that the Feedstock+ pricing model will be successful and that most of or all of the counterparties will enter into offtake agreements with PCT using this pricing model in sufficient numbers, or at all. Additionally, counterparties may attempt to reduce or eliminate the fixed base price, which would reduce and potentially eliminate the effort to de-risk PCT’s operating margins. If PCT is unable to incorporate its Feedstock+ pricing model into its future offtake agreements, in part or at all, or unable to negotiate a sufficiently high fixed base price or procure feedstock above the secondary materials markets pricing index, PCT’s business, financial condition, and results of operations and prospects could be materially adversely impacted.

PCT’s legacy strategic partnership agreements and certain offtake arrangements use pricing formulas that reference the price of virgin polypropylene resin, which is itself correlated to the price of crude oil and natural gas feedstocks. In periods of low or declining crude oil prices, the price of virgin polypropylene may fall significantly, which would reduce the index-linked selling price of PureFive^® resin under such agreements. However, PCT’s costs, including feedstock procurement costs, PreP operating costs, energy costs, logistics costs and fixed plant operating costs, may not decline commensurately with the price of virgin polypropylene, as these costs are driven by different market dynamics. As a result, in low oil price environments, PCT may face a significant mismatch between its selling prices and its cost of production, which could compress or eliminate its operating margins, impair its ability to service its debt obligations and have a material adverse effect on PCT’s business, financial condition, results of operations and prospects. Conversely, in high feedstock cost environments, PCT’s Feedstock+ pricing model is designed to pass through feedstock cost increases to customers, but there is no guarantee that customers will accept such pass-throughs or that the model will function as intended across all market conditions.

S-31

PCT is subject to many hazards and operational risks at its manufacturing facility that can result in potential injury to individuals, disrupt its business, and subject PCT to liability and increased costs, any of which could have a material adverse effect on PCT’s business, financial condition and results of operations.

PCT’s processes involve the controlled use of chemicals, including flammable and combustible solvents operated under elevated pressures and temperatures that are potentially hazardous. As a result, PCT’s operations are subject to various industrial risks including:

•

fires and explosions arising from the handling, storage or release of flammable solvents or other combustible materials;

•

uncontrolled releases or discharges of solvents, or process gases, including emissions to air, discharges to water and releases to soil;

•

wastewater generation and disposal challenges, including the management of liquid waste streams; and

•

dangers resulting from confined operating spaces, equipment failures and maintenance activities.

These risks can result in personal injury, loss of life, catastrophic damage to or destruction of property and equipment or environmental damage, and related legal proceedings, including those commenced by regulators, neighbors, or others. Additionally, PCT may not be able to timely source and install replacement parts for damaged or broken equipment, which could result in an unanticipated interruption or suspension of operations having both financial and customer supply impacts, along with reputational damage and the imposition of liability. Notwithstanding PCT’s extensive safety procedures and training, relief and depressurization systems, emergency shutdown systems, safety instrumented systems and interlocks, fire and gas detection, and fire suppression systems, the risk of injury or property damage cannot be completely eliminated. While PCT believes that it maintains adequate insurance coverage, PCT cannot guarantee that it will be able to maintain adequate insurance at reasonable rates or that its insurance coverage will be adequate to cover future claims that may arise. In the event of an incident or accident, PCT’s business could be disrupted and PCT could be liable for damages, and any such liability could exceed PCT’s resources, and have a negative impact on its financial condition and results of operations. The loss or shutdown over an extended period of operations at any of PCT’s facilities or any losses relating to these risks could also have a material adverse impact on its business, financial condition, results of operations and prospects.

Risks Related to the Market for PureFive^® Resin

The market for PureFive^® resin is still in the development phase and the acceptance of PureFive^® resin by manufacturers and potential customers is not guaranteed.

PCT has agreed to one or more strategic partnership term sheets to enter into offtake agreements with a term of 20 years, whereby PCT guarantees the PureFive^® resin products to meet specific criteria for color and opacity. There is no odor specification in the offtake agreements. Any modifications to the strategic partnership term sheets may require corresponding amendments to PCT’s executed offtake agreements for the Ironton Facility and the Planned Facilities. Pursuant to the strategic partnership term sheets and PCT’s executed offtake agreements, PCT must provide samples of the product to each customer so that the customer may determine if the product meets specifications, regulatory and legal requirements, the customer’s internal policies, and technical, safety, and other qualifications for PureFive^® resin use in the customer’s products. The inability of PCT to provide product of sufficient quantity and quality for sale pursuant to the offtake agreements is likely to materially adversely affect PCT’s business, financial condition, results of operations and prospects. The premium pricing depicted in recent offtake agreements may also adversely affect the acquisition of new customers. Furthermore, future market trends for recycled product, changes in brand owner strategies and changes in consumer preferences for circular or low carbon footprint products could reduce PCT’s customers’ demand for PureFive^® resin, which would be likely to materially adversely affect PCT’s business, financial condition, results of operations and prospects.

S-32

Certain of PCT’s offtake agreements are subject to index pricing, and fluctuation in index prices may adversely impact PCT’s financial results.

PCT expects the price of its PureFive^® resin will command a premium over the price of virgin resin and generally not be subject to fluctuations in the price of virgin polypropylene, but there is no guarantee of this result. While most offtake agreements have been executed using the Feedstock + pricing model, certain of PCT’s legacy strategic partnership agreements’ pricing formulas for PureFive^® resin use a pricing formula based on fixed and index pricing using historical and forecast pricing for virgin resin produced from fossil fuels. If PCT is unable to modify the legacy terms to a Feedstock+ pricing, or should the modeled index price for virgin resin be materially lower than the cost to produce PureFive^® resin from waste polypropylene feedstock, PCT would have to absorb the cost difference between virgin resin and PureFive^® resin production for those customers, and PCT’s business, financial condition, liquidity, results of operations and prospects may be materially adversely impacted.

Competition could reduce demand for PCT’s products or negatively affect PCT’s sales mix or price realization, and failure to compete effectively could materially and adversely affect PCT’s business, financial condition, results of operations and prospects.

PCT operates in a competitive global market for polypropylene sources—both virgin and recycled polypropylene. PCT faces, or may in the future face, competition from:

•

integrated petrochemical producers and resin manufacturers, which have significant scale, established customer relationships, extensive distribution networks and substantial financial and technical resources, and which may develop or acquire recycled polypropylene capabilities or offer virgin polypropylene at prices that make PureFive^® resin less economically attractive;

•

mechanical recyclers of polypropylene, which offer lower-cost recycled polypropylene that, while of lower quality than PureFive^® resin, may be sufficient for certain limited applications and may be preferred by cost-sensitive customers or in jurisdictions where recycled-content requirements do not mandate chemically recycled material;

•

other advanced recyclers utilizing chemical depolymerization, dissolution, pyrolysis or other technologies to produce recycled polypropylene or polypropylene substitutes, some of which may benefit from greater financial, technical or operational resources than PCT and are otherwise acceptable uses under current or future regulations; and

•

customers’ internal circularity platforms, whereby brand owners and manufacturers develop or invest in their own recycled polypropylene supply chains, potentially reducing their reliance on third-party suppliers such as PCT.

Competitors or new entrants might develop new products or technologies that compete with PCT and its proprietary Technology. PCT cannot predict changes that might affect its competitiveness or whether existing competitors or new entrants might develop products that reduce demand for PCT’s PureFive^® resin products. Any of these competitive developments could reduce demand for PureFive^® resin, exert downward pressure on pricing, impair PCT’s ability to attract and retain customers, and have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

In addition, PCT has granted a sublicense of P&G intellectual property back to P&G under the terms of the License Agreement, with a limited right to sublicense by P&G (the “Grant Back”). Under the Grant Back, for five years after July 28, 2020, the aggregate tonnage that was produced under the Grant Back was capped at a certain level per year worldwide. Since July 28, 2025, the aggregate annual tonnage was expanded for each of the six regions worldwide. P&G has agreed that territory under the Grant Back excluded the start of construction of a plant within a certain radius of the Ironton Facility until July 28, 2025, and that P&G will not be bound by the tonnage limitations if certain construction and sales deadlines are not met for future facilities in other regions. If P&G is able to establish production, either on its own or through a sublicense agreement with another partner, in

S-33

any territory, P&G production will now be capped within that territory. If P&G sublicenses the P&G intellectual property under the Grant Back to other manufacturers, the aggregate production of recycled polypropylene resin and supply to markets could increase, adversely impacting PCT’s business, financial condition, results of operations and prospects.

Delays in direct customer commercial sales and customer qualification and application-conversion may adversely impact PCT’s financial results.

In addition to sales through distributors, PCT’s current business model is reliant on sales directly to companies that value sustainability. The process for obtaining customer acceptance of PureFive^® resin as a substitute and/or replacement for traditional virgin or mechanically recycled polypropylene, and the ability to sell into a customer’s supply chain, is typically dependent upon the successful trials from one or more samples of PCT’s PureFive^® resin. These trials could take an extended period of time, depending upon the application into which PCT’s PureFive^® resin will be used. The ability for PCT to fund its operations and service its debt requirements is highly dependent upon PCT’s ability to develop meaningful commercial sales directly to customers. The failure to obtain timely customer approval and extended delays in customers’ adoption of PCT’s PureFive^® resin as a substitute for a customer’s existing polypropylene supplies may have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

Additionally, while PCT has entered into offtake agreements and strategic partnerships with a number of brand owners and manufacturers, the realization of commercial sales volumes is dependent on a customer-by-customer, application-by-application qualification process that is distinct from, and in addition to, the execution of an offtake agreement. Many customers independently evaluate and qualify PureFive^® resin for use in each specific application, which typically involves:

•

laboratory and pilot-scale testing of PureFive^® resin against the customer’s internal material specifications;

•

regulatory and compliance review, including assessment of applicable food-contact, product safety, chemical substance and other regulatory requirements in the relevant jurisdiction; and

•

production trials and validation runs at the customer’s manufacturing facilities to confirm that PureFive^® resin performs as expected in the customer’s specific processing equipment and end-use application.

This qualification process can be lengthy, resource-intensive and uncertain in outcome, and there is no guarantee that any particular customer will successfully qualify PureFive^® resin for any particular application, or that qualification for one application will result in qualification for other applications within the same customer. Delays in, or failures to complete, customer qualification processes could result in offtake agreements generating little or no actual purchase volume, could delay PCT’s ability to generate meaningful commercial revenues, and could have a material adverse effect on PCT’s business, financial condition, results of operations and prospects.

Risks Related to Regulatory Developments

PCT may not be able to meet applicable regulatory requirements for the use of PCT’s PureFive^® resin in food-grade applications, which are feedstock-specific, jurisdiction-specific and application-specific, and, even if the requirements are met, complying on an ongoing basis with the numerous regulatory requirements applicable to the PureFive^® resin and PCT’s facilities will be time-consuming and costly.

The use of PureFive^® resin in food-grade applications is subject to regulation by the U.S. Food and Drug Administration (“FDA”). In order for the PureFive^® resin to be used in food-grade applications, PCT may request one or more Letters of No Objection (“LNOs”) from the FDA.

S-34

The Company has received LNOs from the FDA that allow the Company’s purified product to be used for all food types per the FDA’s Conditions of Use listed and per all applicable authorizations in the food-contact regulations listed in the 21 CFR (Code of Federal Regulations, Title 21).

The process for obtaining further LNOs will include FDA evaluation of the PCT Purification process and the Technology. Each LNO is feedstock-specific, jurisdiction-specific and application-specific, meaning that any change in the source, type, or composition of feedstock used in the PCT process, or any expansion into new food-contact applications will require separate LNO submissions and independent FDA evaluation. All LNOs require that feedstock used in the PCT process should comply with all applicable authorizations, including 21 CFR 174.5—General provisions applicable to indirect food additives, and may be impacted by evolving FDA expectations. The Company is conducting additional testing and plans to make further LNO submissions. In addition, as needed, individual surrogate challenge testing and migration studies will be conducted to simulate articles in contact with food.

The process of obtaining FDA regulatory approval requires the expenditure of substantial time and significant financial resources. The FDA could refuse to approve further LNO applications, a decision may be delayed if the FDA has questions about the data or other aspects of the filing, or the review schedule may be extended if there are a significant number of LNO requests pending. LNOs are also FDA staff opinions rather than formal approvals, and continued reliance depends on consistency in responses. Material changes may require new submissions and could alter prior conclusions. All of the above could have an adverse effect on PCT’s business, financial condition, results of operations and prospects.

Furthermore, changes in regulatory requirements, laws and policies, or evolving interpretations of existing regulatory requirements, laws and policies, may result in increased compliance costs, delays, capital expenditures and other financial obligations that could adversely affect PCT’s business, financial condition, results of operations and prospects.

The use of PureFive^® resin will also be subject to foreign regulatory schemes in Europe and Asia, including, but not limited to, the European Commission (the “EC”), the European Food Safety Authority (the “EFSA”), the Federal Agency for the Safety of the Food Chain (the “FASFC”) in Belgium, the Association of Southeast Asian Nations (the “ASEAN”), and the Thai Food and Drug Administration (the “TFDA”) in Thailand. The European Union (the “EU”) has a general framework of rules for clearing and marketing food packaging materials through a positive list system as well as specific rules for recycled plastics. PCT is currently advancing the authorization process in Europe and hopes to receive the final authorizations in 2026.

PCT also expects to encounter regulations in most, if not all, of the countries in which PCT may seek to expand, and PCT cannot be sure that it will be able to obtain necessary approvals in a timely manner or at all. If PCT’s PureFive^® resin does not meet applicable regulatory requirements in a particular country or at all, then PCT may face hindered or reduced market demand in those countries and PCT’s business, financial condition, results of operations and prospects may be adversely affected.

The various regulatory schemes applicable to PCT’s PureFive^® resin will continue to apply following initial approval. Monitoring regulatory changes and ensuring the Company’s ongoing compliance with applicable requirements is time-consuming and may affect PCT’s business, financial condition, results of operation and prospects. If PCT fails to comply with such requirements on an ongoing basis, PCT may be subject to fines or other penalties, or may be prevented from selling PureFive^® resin products, and PCT’s business, financial condition, results of operation and prospects may be harmed.

Legislative, regulatory or judicial developments could affect PCT’s business, financial condition, results of operations and prospects.

PCT’s activities and plants are subject to extensive air, water and other environmental and workplace safety laws and regulations at the federal and state level. In addition, PCT will be subject to additional regulatory

S-35

regimes upon expanding to new regions, including foreign regulatory authorities in the EU, such as the EC, the EFSA, and the FASFC, foreign regulatory authorities in the ASEAN such as the TFDA, and similar regulatory authorities. Some of these laws require or may require PCT to operate under a number of environmental permits. These laws, regulations and permits can often require pollution control equipment or operational changes to limit actual or potential impacts to the environment. These laws, regulations and permit conditions evolve in time and may become more difficult to comply with. A violation of these laws, regulations or permit conditions could result in substantial fines, damages, criminal sanctions, permit revocations and/or a plant shutdown. PCT has experienced, and may in the future experience, violations of applicable environmental laws, regulations or permit conditions, including with respect to wastewater generation and disposal to the extent applicable. PCT cannot provide assurance that it will not face further regulatory scrutiny, additional citations, or enforcement action in connection with these or other violations, or that any such action will not result in substantial fines, damages, criminal sanctions, permit revocations and/or a plant shutdown.

In addition, proposals relating to recycling or recycling content and prohibitions on certain types of plastic products have been introduced and/or adopted in various jurisdictions, and it is anticipated that similar legislation or regulations may be proposed in the future at federal, state, and local levels, both within the U.S. and elsewhere. There is a risk that PureFive^® resin may not qualify as recycled content or post-consumer recycled content under one or more applicable state laws, federal regulations, customer sustainability programs or third-party certification schemes, whether due to the nature of PCT’s purification process or evolving interpretations of applicable standards. If PureFive^® resin is determined not to qualify as recycled content or post-consumer recycled content under standards that are material to PCT’s customers, demand for PureFive^® resin could be materially reduced, customers may seek alternative suppliers or materials, and PCT’s business, financial condition, results of operations and prospects could be materially adversely affected.

Risks Related to Human Capital Management

PCT is dependent on management and key personnel, and PCT’s business would suffer if it fails to retain its key personnel and attract additional highly skilled employees.

PCT’s success is dependent on the specialized skills of its management team and key operating personnel. This may present particular challenges as PCT operates in a highly specialized industry sector, which may make replacement of its management team and key operating personnel difficult. A loss of the management team members or key employees, or their failure to satisfactorily perform their responsibilities, could affect a variety of roles. Loss of key personnel may also heighten any operational exposures should staff be pulled into multiple activities simultaneously due to challenges related to retention and recruitment, and may result in significant attrition of high caliber and high potential employees, loss of key skills and a noticeable decline in employee morale. Ultimately, the loss of high caliber and high potential team members could have an adverse effect on PCT’s business, financial condition, results of operations and prospects.

PCT’s future success will depend on its ability to identify, hire, develop, motivate and retain highly qualified personnel for all areas of its organization, particularly research and development, recycling technology, operations and sales. Trained and experienced personnel are in high demand and may be in short supply, and tight labor markets, evolving workplace expectations and immigration/work-authorization constraints could further limit availability and increase costs. Many of the companies with which PCT competes for experienced employees have greater resources than PCT does and may be able to offer more attractive terms of employment. In addition, PCT invests significant time and expense in training employees, which increases their value to competitors that may seek to recruit them. PCT may not be able to attract, develop and maintain the skilled workforce necessary to operate its business, and labor expenses may increase as a result of a shortage in the supply of qualified personnel, which may negatively impact PCT’s business, financial condition, results of operations and prospects.

We estimate that the net proceeds to us from this offering will be approximately $242.0 million (or approximately $278.3 million if the underwriters exercise their over-allotment option in full), after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

The Green Convertible Notes bear interest at a rate of 7.25% per year and mature on August 15, 2030. As of March 31, 2026, $250.0 million aggregate principal amount at maturity of the Green Convertible Notes remained outstanding.

S-39

DESCRIPTION OF NOTES

We will issue the 4.75% Convertible Senior Notes due 2032 (the “notes”) under a base indenture (the “base indenture”), to be dated as of the date of initial issuance of the notes, between us and U.S. Bank Trust Company, National Association, as trustee (the “trustee”), as supplemented by a first supplemental indenture with respect to the notes (the “supplemental indenture”), between us and the trustee. In this section, we refer to the base indenture, as supplemented by the supplemental indenture, collectively as the “indenture.” This description of the notes supplements and, to the extent it is inconsistent, replaces the description of the general provisions of the notes and the base indenture in the accompanying prospectus. The terms of the notes include those expressly set forth in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

You may request a copy of the indenture from us as described under the caption “Where You Can Find More Information.”

The following description is a summary of the material provisions of the notes and the indenture and does not purport to be complete. This summary is subject to and is qualified by reference to all the provisions of the notes and the indenture, including the definitions of certain terms used in the indenture. We urge you to read these documents because they, and not this description, define your rights as a holder of the notes.

For purposes of this description, references to “we,” “our” and “us” refer only to PureCycle Technologies, Inc. and not to its subsidiaries.

General

The notes will:

•

be our general unsecured, senior obligations;

•

initially be limited to an aggregate principal amount of $250,000,000 (or $287,500,000 if the underwriters’ over-allotment option is exercised in full);

•

bear cash interest from June 15, 2026 at an annual rate of 4.75% payable semi-annually in arrears on January 1 and July 1 of each year, beginning on January 1, 2027;

•

be subject to redemption at our option, in whole or in part (subject to the partial redemption limitation described below), on a redemption date on or after July 6, 2029 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date as described under the caption “—Optional Redemption;”

•

be subject to repurchase by us at the option of the holders of the notes on July 8, 2030 (the “specified repurchase date”), at a specified repurchase date repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the specified repurchase date;

•

be subject to repurchase by us at the option of the holders following a “fundamental change” (as defined under the caption “—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes”), subject to certain conditions and limited exceptions, at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date;

S-42

•

mature on July 1, 2032, unless earlier converted, redeemed or repurchased;

•

be issued in minimum denominations of $1,000 and integral multiples of $1,000; and

•

initially be represented by one or more registered notes in global form, but in certain limited circumstances may be represented by notes in definitive form (see the caption “—Book-Entry, Settlement and Clearance”).

Subject to satisfaction of certain conditions and during the periods described below, the notes may be converted at an initial conversion rate of 90.2242 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $11.08 per share of common stock).

We will settle conversions of notes by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, as described under the caption “—Conversion Rights—Settlement upon Conversion.” You will not receive any separate cash payment for interest, if any, accrued and unpaid to the conversion date except under the limited circumstances described below.

The indenture will not limit the amount of debt, including secured debt, that may be issued by us or our subsidiaries under the indenture or otherwise. The indenture will not contain any financial covenants and will not restrict us from paying dividends or issuing or repaying, prepaying or repurchasing our other securities or indebtedness. Other than restrictions described under the caption “—Repurchase at the Option of Holders—Fundamental Change Permits Holders to Require Us to Repurchase Notes” and “—Consolidation, Merger and Sale of Assets” below and except for the provisions set forth under the caption “—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption,” the indenture will not contain any covenants or other provisions designed to afford holders of the notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect such holders. The notes will not be guaranteed by any of our subsidiaries.

We may, without the consent of, or notice to, the holders, reopen the indenture for the notes and issue additional notes under the indenture with the same terms as the notes offered hereby (other than differences in the issue date, the issue price, interest accrued prior to the issue date of such additional notes and, if applicable, restrictions on transfer in respect of such additional notes) in an unlimited aggregate principal amount; provided that if any such additional notes are not fungible with the notes initially offered hereby for U.S. federal income tax or securities law purposes, such additional notes will have one or more separate CUSIP numbers.

We do not intend to list the notes on any securities exchange or any automated dealer quotation system.

Except to the extent the context otherwise requires, we use the term “notes” in this prospectus supplement to refer to each $1,000 principal amount of notes. In this prospectus supplement, we use the term “common stock” to refer to our common stock, par value $0.001 per share. References in this prospectus supplement to a “holder” or “holders” of notes that are held through The Depository Trust Company (“DTC”) are references to owners of beneficial interests in such notes, unless the context otherwise requires. However, we and the trustee will treat the person in whose name the notes are registered (Cede & Co., in the case of notes held through DTC) as the owner of such notes for all purposes. References herein to the “close of business” refer to 5:00 p.m., New York City time, and to the “open of business” refer to 9:00 a.m., New York City time.

Purchase and Cancellation

For purposes of the notes, the description below under this section titled “—Purchase and Cancellation” supersedes, in its entirety, the information in the accompanying prospectus under the caption “Description of Debt Securities—Purchase and Cancellation.”

S-43

We will cause all notes surrendered for payment at maturity, repurchase on the specified repurchase date or upon a fundamental change, redemption, registration of transfer or exchange or conversion, if surrendered to us or any of our agents or subsidiaries, to be delivered to the trustee for cancellation and they will no longer be considered “outstanding” under the indenture upon such payment at maturity, repurchase on the specified repurchase date or upon a fundamental change, redemption, registration of transfer or exchange or conversion, as the case may be. All notes delivered to the trustee shall be cancelled promptly by the trustee in accordance with its customary procedures upon our written request. Except for notes surrendered for registration of transfer or exchange, no notes shall be authenticated in exchange for any notes cancelled as provided in the indenture.

We may, to the extent permitted by law, and directly or indirectly (regardless of whether such notes are surrendered to us), repurchase notes in the open market or otherwise, whether by us or our subsidiaries or through a privately negotiated transaction or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case, without the consent of or notice to the holders of the notes. We may, at our option and to the extent permitted by applicable law, reissue, resell or surrender to the trustee for cancellation any notes that we may repurchase, in the case of a reissuance or resale, so long as such notes do not constitute restricted securities upon such reissuance or resale; provided that if any such reissued or resold notes are not fungible with the notes initially offered hereby for U.S. federal income tax or securities law purposes, such reissued or resold notes will have one or more separate CUSIP numbers. Any notes that we may repurchase will be considered outstanding for all purposes under the indenture (other than, at any time when such notes are held by us, any of our subsidiaries or affiliates or any subsidiary of any of our affiliates, for the purpose of determining whether holders of the requisite aggregate principal amount of notes have concurred in any direction, consent, waiver or other action under the indenture) unless and until such time we surrender them to the trustee for cancellation and, upon receipt of a written order from us, the trustee will cancel all notes so surrendered.

Payments on the Notes; Paying Agent and Registrar; Transfer and Exchange

We will pay, or cause the paying agent to pay, the principal of, and interest on, notes in global form registered in the name of or held by DTC or its nominee by wire transfer in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global note.

We will pay, or cause the paying agent to pay, the principal of any certificated notes at the office or agency designated by us for that purpose. We have initially designated the trustee as our paying agent and registrar and its agency in the continental United States of America as a place where notes may be presented for payment or for registration of transfer. We may, however, change the paying agent or registrar without prior notice to the holders of the notes, and we may act as paying agent or registrar. Interest on certificated notes will be payable (i) to holders having an aggregate principal amount of $5,000,000 or less, by check mailed to the holders of these notes and (ii) to holders having an aggregate principal amount of more than $5,000,000, either by check mailed to each holder or, upon application by such a holder to the registrar not later than the relevant regular record date, by wire transfer in immediately available funds to that holder’s account within the United States if such holder has provided us, the trustee or the paying agent (if other than the trustee) with the requisite information necessary to make such wire transfer, which application shall remain in effect until the holder notifies, in writing, the registrar to the contrary.

A holder of notes may transfer or exchange notes at the office of the registrar in accordance with the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but we may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture.

We are not required to transfer or exchange any note selected for redemption or surrendered for conversion or required repurchase on the specified repurchase date or on a fundamental change repurchase date. A holder of

S-44

a beneficial interest in a note in global form may transfer or exchange such beneficial interest in accordance with the indenture and the applicable procedures of DTC. See the caption “—Book-Entry, Settlement and Clearance.”

The registered holder of a note will be treated as its owner for all purposes.

Interest

The notes will bear cash interest at a rate of 4.75% per year until maturity. Interest on the notes will accrue from June 15, 2026 or from the most recent date on which interest has been paid or duly provided for. Interest will be payable semiannually in arrears on January 1 and July 1 of each year (each, an “interest payment date”), beginning on January 1, 2027.

Interest will be paid to the person in whose name a note is registered at the close of business on May 15 or November 15 (whether or not a business day), as the case may be, immediately preceding the relevant interest payment date (each, a “regular record date”). Interest on the notes will be computed on the basis of a 360-day year composed of twelve 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

If any interest payment date, the maturity date, any redemption date, the specified repurchase date or any fundamental change repurchase date falls on a day that is not a business day, the required payment will be made on the next succeeding business day with the same force and effect as if made on such scheduled payment date, and no interest on such payment will accrue in respect of the delay. The term “business day” means, with respect to any note, any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.

Unless the context otherwise requires, all references to interest in this prospectus supplement include additional interest, if any, payable at our election as the sole remedy relating to the failure to comply with our reporting obligations as described under the caption “—Events of Default.”

Ranking

The notes will be our general unsecured obligations that will rank senior in right of payment to all of our indebtedness that is expressly subordinated in right of payment to the notes. The notes will rank equal in right of payment with all of our existing and future liabilities that are not so subordinated, including our existing 7.25% Convertible Senior Notes due 2030 (the “Green Convertible Notes”). The notes will effectively rank junior to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness, including any outstanding borrowings under our $200 million revolving credit facility with Sylebra Capital (the “Revolving Credit Facility”). In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure secured indebtedness will be available to pay obligations on the notes only after all indebtedness under such secured indebtedness has been repaid in full from such assets. The notes will rank structurally junior to all indebtedness and other liabilities (including trade payables) of our current or future subsidiaries, including the revenue bonds issued by or on behalf of certain of our subsidiaries (the “Revenue Bonds”).

Substantially all of our consolidated assets are held by, and substantially all of our business is conducted through, our subsidiaries. The notes will not be guaranteed by any of our subsidiaries. Any subsidiaries that we may form in the future will be separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay amounts due with respect to the notes or to make any funds available therefor, whether by dividends, loans or other payments. Our right to receive any assets of any of our subsidiaries upon such subsidiary’s bankruptcy, liquidation or reorganization, and, therefore, the right of the holders of notes to participate in those assets, will be subject to prior claims of creditors of the subsidiary, including trade creditors, and such subsidiary may not have sufficient assets remaining to make any payments to us as a stockholder or otherwise. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding.

S-45

The ability of our subsidiaries to pay dividends and make other payments to us is restricted by the terms of the credit agreement governing the Revolving Credit Facility and may be restricted by, among other things, applicable corporate and other laws and regulations, our future debt instruments as well as agreements to which our subsidiaries may become a party. We may not be able to pay the cash portions of any settlement amount upon conversion of the notes, or to pay cash for the specified repurchase date repurchase price on the specified repurchase date or the fundamental change repurchase price upon a fundamental change if a holder requires us to repurchase notes as described below. See the caption “Risk Factors—Risks Related to the Notes—We may not have the ability to raise the funds necessary to settle conversions of the notes or the Green Convertible Notes in cash or to repurchase the notes on July 8, 2030, the Green Convertible Notes on August 15, 2027 or the notes or the Green Convertible Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the notes or the Green Convertible Notes.”

Optional Redemption

No “sinking fund” is provided for the notes, which means that we are not required to redeem or retire the notes periodically. Prior to July 6, 2029, the notes will not be redeemable. On a redemption date on or after July 6, 2029, we may redeem for cash all or any portion of the notes (subject to the partial redemption limitation set forth below), at our option, if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption. In the case of any optional redemption, we will provide not less than 35 nor more than 55 scheduled trading days’ written notice before the redemption date to the trustee, the paying agent (if other than the trustee), the conversion agent (if other than the trustee) and each holder of notes, and the redemption price will be equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date (unless the redemption date falls after a regular record date but on or prior to the immediately succeeding interest payment date, in which case we will pay the full amount of accrued and unpaid interest to the holder of record as of the close of business on such regular record date on, or at our election, before, such interest payment date, and the redemption price will be equal to 100% of the principal amount of the notes to be redeemed).

However, if, in accordance with the provisions described in the third paragraph under the caption “—Conversion Rights—Settlement upon Conversion,” we elect to settle all conversions of notes called for redemption (or deemed called for redemption as described below under the caption “—Conversion Rights—General”) with a conversion date that occurs during the related “redemption period” (as defined under the caption “—Conversion Rights—General”) by physical settlement, then we may instead elect to choose a redemption date that is a business day not less than 15 calendar days nor more than 55 scheduled trading days after the date we send such notice of redemption. The redemption date set forth in the relevant notice of redemption must be a business day that is scheduled to be a business day as of the date of such notice of redemption, and we may not specify a redemption date that falls on or after the 31st scheduled trading day immediately preceding the maturity date.

S-46

The “last reported sale price” of our common stock (or other security for which a closing sale price must be determined) on any date means the closing sale price per share (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in composite transactions for the principal U.S. national or regional securities exchange on which our common stock (or such other security) is traded. If our common stock (or such other security) is not listed for trading on a U.S. national or regional securities exchange on the relevant date, the “last reported sale price” will be the last quoted bid price for our common stock (or such other security) in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or a similar organization. If our common stock (or such other security) is not so quoted, the “last reported sale price” will be the average of the mid-point of the last bid and ask prices for our common stock (or such other security) on the relevant date from each of at least three nationally recognized independent investment banking firms selected by us for this purpose. The “last reported sale price” will be determined without regard to after-hours trading or any other trading outside of regular trading session hours.

Except for purposes of determining amounts due upon conversion, “trading day” means a day on which (i) trading in our common stock (or other security for which a closing sale price must be determined) generally occurs on The Nasdaq Capital Market or, if our common stock (or such other security) is not then listed on The Nasdaq Capital Market, on the principal other U.S. national or regional securities exchange on which our common stock (or such other security) is then listed or, if our common stock (or such other security) is not then listed on a U.S. national or regional securities exchange, on the principal other market on which our common stock (or such other security) is then traded, and (ii) a last reported sale price for our common stock (or closing sale price for such other security) is available on such securities exchange or market. If our common stock (or such other security) is not so listed or traded, “trading day” means a “business day.”

With respect to any notes that are called (or deemed called) for redemption and converted in connection with a notice of redemption as described under the caption “—Conversion Rights—General,” we will, under certain circumstances, increase the conversion rate for the notes so surrendered for conversion by a number of additional shares as described under the caption “—Conversion Rights—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption.”

If we elect to redeem less than all of the outstanding notes, at least $75,000,000 aggregate principal amount of notes must be outstanding and not subject to redemption as of, and after giving effect to, delivery of the relevant notice of redemption (such requirement, the “partial redemption limitation”). If we decide to redeem less than all of the outstanding notes and the notes to be redeemed are global notes, the notes to be redeemed will be selected by DTC in accordance with applicable DTC procedures. If we decide to redeem less than all of the outstanding notes and the notes to be redeemed are not global notes then held by DTC, the trustee will select the notes to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis, or by another method the trustee considers to be fair and appropriate.

If the trustee (or DTC, with respect to global notes) selects a portion of your notes for partial redemption and you convert a portion of the same notes, the converted portion will be deemed to be from the portion selected for redemption, subject to the applicable procedures of DTC.

In the event of any redemption in part, we will not be required to register the transfer of or exchange for other notes any note so selected for redemption, in whole or in part, except the unredeemed portion of any note being redeemed in part.

No notes may be redeemed if the principal amount of the notes has been accelerated, and such acceleration has not been rescinded, on or prior to the redemption date (except in the case of an acceleration resulting from a default by us in the payment of the redemption price with respect to such notes).

S-47

Conversion Rights

General

The conversion rate for the notes will initially be 90.2242 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $11.08 per share of common stock). Upon conversion of a note, we will satisfy our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, all as set forth below under the caption “—Settlement upon Conversion.” If we satisfy our conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of our common stock, the amount of cash and shares of common stock, if any, due upon conversion will be based on a “daily conversion value” (as defined under the caption “—Settlement upon Conversion”) calculated on a proportionate basis for each trading day in a 30 trading day “observation period” (as defined under the caption “—Settlement upon Conversion”). The trustee will initially act as the conversion agent.

A holder may convert fewer than all of such holder’s notes so long as the notes converted are an integral multiple of $1,000 principal amount.

If we call (or are deemed to have called) a note for redemption, a holder of such note called (or deemed called) for redemption may convert its note called (or deemed called) for redemption from, and including, the date of issuance of a notice of redemption with respect to such note until the close of business on the second scheduled trading day immediately preceding the applicable redemption date unless we fail to pay the redemption price (in which case a holder of a note called (or deemed called) for redemption may convert such note until the close of business on the scheduled trading day immediately preceding the date on which the redemption price has been paid or duly provided for) (any such period, a “redemption period”). If a holder elects to convert a note called (or deemed called) for redemption during the related redemption period, we will, under certain circumstances, increase the conversion rate for such note as described under the caption “—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption.” Accordingly, if we elect to redeem less than all of the outstanding notes as described under the caption “—Optional Redemption,” holders of the notes not called (or deemed called) for redemption will not be entitled to an increased conversion rate for conversions of such notes (on account of the notice of redemption) during the related redemption period, except in the limited circumstances set forth in the immediately succeeding paragraph.

If we elect to redeem less than all of the outstanding notes as described under the caption “—Optional Redemption,” and the holder of any note (or any owner of a beneficial interest in any global note) is reasonably not able to determine, before the close of business on the 29th scheduled trading day immediately before the relevant redemption date (or if, as permitted under the caption “—Optional Redemption,” we deliver a notice of redemption not less than 15 calendar days nor more than 55 scheduled trading days prior to the related redemption date, then prior to close of business on the 14th calendar day immediately before the relevant redemption date), whether such note or beneficial interest, as applicable, is to be redeemed pursuant to such redemption (and, as a result thereof, convertible on account of the related notice of redemption in accordance with the provisions of the indenture), then the notes converted by such holder during the related redemption period will be deemed to be of a note called for redemption (and each such conversion will be deemed “in connection with” the relevant notice of redemption).

Upon conversion, you will not receive any separate cash payment for accrued and unpaid interest, if any, except as described below. We will not issue fractional shares of our common stock upon conversion of notes. Instead, we will pay cash in lieu of delivering any fractional share as described under the caption “—Settlement upon Conversion.” Our payment and delivery, as the case may be, to you of the cash, shares of our common

S-48

stock or a combination thereof, as the case may be, into which a note is convertible will be deemed to satisfy in full our obligation to pay:

•

the principal amount of the note; and

•

accrued and unpaid interest, if any, to, but not including, the relevant conversion date.

As a result, accrued and unpaid interest, if any, to, but not including, the relevant conversion date will be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon a conversion of notes into a combination of cash and shares of our common stock, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion.

Notwithstanding the immediately preceding paragraph, if notes are converted after the close of business on a regular record date for the payment of interest and prior to the open of business on the corresponding interest payment date, holders of such notes at the close of business on such regular record date will receive the full amount of interest payable on such notes on the corresponding interest payment date notwithstanding the conversion. Notes surrendered for conversion during the period from the close of business on any regular record date to the open of business on the immediately following interest payment date must be accompanied by funds equal to the amount of interest payable on the notes so converted; provided that no such payment need be made:

•

for conversions following the close of business on the regular record date immediately preceding the maturity date;

•

if we have specified a redemption date that is after a regular record date and on or prior to the second business day immediately following the corresponding interest payment date;

•

if we have specified a fundamental change repurchase date that is after a regular record date and on or prior to the business day immediately following the corresponding interest payment date; or

•

to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such note.

Therefore, for the avoidance of doubt, all record holders on the regular record date immediately preceding the maturity date will receive the full interest payment due on the maturity date in cash regardless of whether their notes have been converted following such regular record date.

If a holder converts notes, we will pay any documentary, stamp or similar issue or transfer tax due on any issuance or delivery of any shares of our common stock upon the conversion, unless the tax is due because the holder requests such shares to be issued in a name other than the holder’s name, in which case the holder will pay that tax.

Certain Distributions Notice

If, prior to the close of business on the business day immediately preceding April 1, 2032, we elect to:

•

distribute to all or substantially all holders of our common stock any rights, options or warrants (other than in connection with a stockholder rights plan prior to separation of such rights from our common stock) entitling them, for a period of not more than 60 calendar days after the announcement date of such distribution, to subscribe for or purchase shares of our common stock at a price per share that is less than the average of the last reported sale prices of our common stock for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the date of announcement of such distribution; or

•

distribute to all or substantially all holders of our common stock our assets, securities or rights to purchase our securities (other than in connection with a stockholder rights plan prior to separation of such rights from our common stock), which distribution has a per share value, as reasonably determined by us in good faith, exceeding 10% of the last reported sale price of our common stock on the trading day preceding the date of announcement for such distribution,

S-49

then, in either case, we must notify the holders of the notes, the trustee and the conversion agent (if other than the trustee) at least 36 scheduled trading days prior to the ex-dividend date for such distribution (or, if later in the case of any such separation of rights issued pursuant to a stockholder rights plan, as soon as reasonably practicable after we become aware that such separation or triggering event has occurred or will occur); provided, however, that if we are then otherwise permitted to settle conversions of notes by physical settlement (and, for the avoidance of doubt, have not irrevocably agreed to settle by some other method), then we may instead elect to provide such notice at least five scheduled trading days prior to such ex-dividend date, in which case we shall be required to settle all conversions of notes with a conversion date occurring during the period on or after the date we provide such notice and before such ex-dividend date (or, if earlier, the date we announce that such issuance or distribution will not take place) by physical settlement, and we shall describe the same in such notice.

Conversion Procedures

If you hold a beneficial interest in a global note, to convert you must comply with DTC’s procedures for converting a beneficial interest in a global note and, if required, pay funds equal to interest payable on the next interest payment date to which you are not entitled. As such, if you are a beneficial owner of the notes, you must allow for sufficient time to comply with DTC’s procedures if you wish to exercise your conversion rights. If you hold a certificated note, to convert you must:

•

complete and manually sign the conversion notice on the back of the note, or a facsimile of the conversion notice;

•

deliver the conversion notice, which is irrevocable, and the note to the conversion agent;

•

if required, furnish appropriate endorsements and transfer documents; and

•

if required, pay funds equal to interest payable on the next interest payment date to which you are not entitled.

We will pay any documentary, stamp or similar issue or transfer tax on the issuance or delivery of any shares of our common stock upon conversion of the notes, unless the tax is due because the holder requests such shares to be issued in a name other than the holder’s name, in which case the holder will pay the tax.

We refer to the date you comply with the relevant procedures for conversion described above as the “conversion date.”

If a holder has already delivered a repurchase notice as described under the caption “—Repurchase at the Option of Holders” with respect to a note, the holder may not surrender that note for conversion until the holder has validly withdrawn the repurchase notice in accordance with the relevant provisions of the indenture. If a holder submits its notes for required repurchase, the holder’s right to withdraw the repurchase notice and convert the notes that are subject to repurchase will terminate at the close of business on the business day immediately preceding the specified repurchase date or the relevant fundamental change repurchase date, as applicable.

Settlement upon Conversion

Upon conversion, we may choose to pay or deliver, as the case may be, either cash (“cash settlement”), shares of our common stock (“physical settlement”) or a combination of cash and shares of our common stock (“combination settlement”), as described below. We refer to each of these settlement methods as a “settlement method.”

All conversions of notes called for redemption (or deemed called for redemption) for which the relevant conversion date occurs during the related redemption period, and all conversions for which the relevant conversion date occurs on or after April 1, 2032, will be settled using the same settlement method. Except for any such conversions for which the relevant conversion date occurs during a redemption period, and any conversions

S-50

for which the relevant conversion date occurs on or after April 1, 2032, and except to the extent we have irrevocably elected physical settlement as described under the caption “—Certain Distributions Notice,” in the related notice described therein or we have previously made an irrevocable election with respect to all subsequent conversions of notes as described below, we will use the same settlement method for all conversions with the same conversion date, but we will not have any obligation to use the same settlement method with respect to conversions with different conversion dates. That is, prior to April 1, 2032, subject to the immediately preceding sentence, we may choose for notes converted on one conversion date to settle conversions using one settlement method (for example, physical settlement), and choose for notes converted on another conversion date to use a different settlement method (for example, cash settlement or combination settlement).

If we elect a settlement method, we will inform holders so converting, the trustee and the conversion agent (if other than the trustee), in writing, of the settlement method we have selected no later than the close of business on the trading day immediately following the related conversion date (or in the case of any conversions (x) of notes called for redemption (or deemed called for redemption) for which the relevant conversion date occurs during the related redemption period, in the related notice of redemption, (y) of notes for which the relevant conversion date occurs on or after April 1, 2032, no later than April 1, 2032, or (z) of notes for which we have irrevocably elected physical settlement as described under the caption “—Certain Distributions Notice,” in the related notice described therein or for which we have previously made an irrevocable election with respect to all subsequent conversions of notes, as described below). If we do not timely elect a settlement method, we will no longer have the right to elect a settlement method with respect to any conversion on such conversion date or during such period, and we will be deemed to have elected the “default settlement method” (as defined below) with respect to such conversion. If we elect (or are deemed to have elected) combination settlement, but we do not timely notify converting holders of the specified dollar amount per $1,000 principal amount of notes to be converted, such specified dollar amount will be deemed to be $1,000. For the avoidance of doubt, our failure to timely elect a settlement method or specify as applicable a specified dollar amount will not constitute a default under the indenture.

The “default settlement method” will initially be physical settlement. By written notice to holders of the notes, the trustee and the conversion agent (if other than the trustee), we may, from time to time, change the default settlement method prior to April 1, 2032. In addition, by written notice to holders of the notes, we may, prior to April 1, 2032, at our option, irrevocably elect to fix the settlement method to any settlement method that we are then permitted to elect, including combination settlement with a specified dollar amount per $1,000 principal amount of notes of $1,000 or with an ability to continue to set the specified dollar amount per $1,000 principal amount of notes at or above a specific amount set forth in such election notice (any such election, an “irrevocable election”). If we change the default settlement method or we irrevocably elect to fix the settlement method, in either case, to combination settlement with an ability to continue to set the specified dollar amount per $1,000 principal amount of notes at or above a specific amount, we will, after the date of such change or election, as the case may be, inform holders converting their notes, the trustee and the conversion agent (if other than the trustee), in writing, of such specified dollar amount no later than the relevant deadline for election of a settlement method as described in the immediately preceding paragraph, or, if we do not timely notify holders, such specified dollar amount will be the specific amount set forth in the change or election notice or, if no specific amount was set forth in the change or election notice, such specified dollar amount will be $1,000 per $1,000 principal amount of notes. A change in the default settlement method or an irrevocable election will apply to all note conversions on conversion dates occurring subsequent to delivery of such notice; provided, however, that no such change or election will affect any settlement method theretofore elected (or deemed to be elected) with respect to any note. For the avoidance of doubt, such an irrevocable election, if made, will be effective without the need to amend the indenture or the notes, including pursuant to the provisions described in clause (13) of the third paragraph under the caption “—Modification and Amendment” below. However, we may nonetheless choose to execute such an amendment at our option.

If we change the default settlement method or we irrevocably fix the settlement method pursuant to the provisions described in the preceding paragraph, then, concurrently with providing notice to holders of notes, the

S-51

trustee and the conversion agent (if other than the trustee) of such change or election, we will either post the default settlement method or fixed settlement method, as the case may be, on our website or disclose the same in a current report on Form 8-K (or any successor form) that is filed with the SEC.

Settlement amounts will be computed as follows:

•

if we elect (or are deemed to have elected) physical settlement, we will deliver to the converting holder in respect of each $1,000 principal amount of notes being converted a number of shares of common stock equal to the conversion rate;

•

if we elect (or are deemed to have elected) cash settlement, we will pay to the converting holder in respect of each $1,000 principal amount of notes being converted cash in an amount equal to the sum of the daily conversion values for each of the 30 consecutive trading days during the related observation period; and

•

if we elect (or are deemed to have elected) combination settlement, we will pay or deliver, as the case may be, to the converting holder in respect of each $1,000 principal amount of notes being converted a “settlement amount” equal to the sum of the daily settlement amounts for each of the 30 consecutive trading days during the related observation period.

If more than one note is surrendered for conversion at any one time by the same holder, the conversion obligation with respect to such notes shall be computed on the basis of the aggregate principal amount of the notes surrendered.

The “daily settlement amount,” for each of the 30 consecutive trading days during the relevant observation period, shall consist of:

•

cash equal to the lesser of (i) the maximum cash amount per $1,000 principal amount of notes to be received upon conversion as specified in the notice specifying our chosen settlement method (or deemed specified as set forth above) (the “specified dollar amount”), if any, divided by 30 (such quotient, the “daily measurement value”) and (ii) the daily conversion value; and

•

if the daily conversion value exceeds the daily measurement value, a number of shares of common stock equal to (i) the difference between the daily conversion value and the daily measurement value, divided by (ii) the daily VWAP for such trading day.

The “daily conversion value” means, for each of the 30 consecutive trading days during the relevant observation period, one-thirtieth (1/30th) of the product of (1) the conversion rate on such trading day and (2) the daily VWAP for such trading day.

The “daily VWAP” means, for each of the 30 consecutive trading days during the relevant observation period, the per share volume-weighted average price as displayed under the heading “Bloomberg VWAP” on Bloomberg page “PCT <equity> AQR” (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such trading day (or if such volume-weighted average price is unavailable, the market value of one share of our common stock on such trading day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by us). The “daily VWAP” will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

The “observation period” with respect to any note surrendered for conversion means:

•

subject to the immediately succeeding bullet point, if the relevant conversion date occurs prior to April 1, 2032, the 30 consecutive trading day period beginning on, and including, the second trading day immediately succeeding such conversion date;

S-52

•

with respect to any notes called for redemption (or deemed called for redemption) as described above under the caption “—General,” if the relevant conversion date occurs during the related redemption period, the 30 consecutive trading days beginning on, and including, the 31st scheduled trading day immediately preceding such redemption date; and

•

subject to the immediately preceding bullet point, if the relevant conversion date occurs on or after April 1, 2032, the 30 consecutive trading days beginning on, and including, the 31st scheduled trading day immediately preceding the maturity date.

For the purposes of determining amounts due upon conversion only, “trading day” means a day on which (i) there is no “market disruption event” (as defined below) and (ii) trading in our common stock generally occurs on the Nasdaq Capital Market or, if our common stock is not then listed on the Nasdaq Capital Market, on the principal other U.S. national or regional securities exchange on which our common stock is then listed or, if our common stock is not then listed on a U.S. national or regional securities exchange, on the principal other market on which our common stock is then listed or admitted for trading. If our common stock is not so listed or admitted for trading, “trading day” means a “business day.”

“Scheduled trading day” means a day that is scheduled to be a trading day on the principal U.S. national or regional securities exchange or market on which our common stock is listed or admitted for trading. If our common stock is not so listed or admitted for trading, “scheduled trading day” means a “business day.”

For the purposes of determining amounts due upon conversion, “market disruption event” means (i) a failure by the primary U.S. national or regional securities exchange or market on which our common stock is listed or admitted for trading to open for trading during its regular trading session or (ii) the occurrence or existence prior to 1:00 p.m., New York City time, on any scheduled trading day for our common stock for more than one half-hour period in the aggregate during regular trading hours of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the relevant stock exchange or otherwise) in our common stock or in any options contracts or futures contracts relating to our common stock.

Except as described under the captions “—Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or Notice of Redemption” and “—Recapitalizations, Reclassifications and Changes of Our Common Stock,” we will deliver the consideration due in respect of conversion on the second business day immediately following the relevant conversion date, if we elect physical settlement (provided that, with respect to any conversion date following the regular record date immediately preceding the maturity date where physical settlement applies to the related conversion, we will settle any such conversion on the maturity date), or on the second business day immediately following the last trading day of the relevant observation period, in the case of any other settlement method.

We will pay cash in lieu of delivering any fractional share of common stock issuable upon conversion based on the daily VWAP for the relevant conversion date (in the case of physical settlement) or based on the daily VWAP for the last trading day of the relevant observation period (in the case of combination settlement).

Each conversion will be deemed to have been effected as to any notes surrendered for conversion on the conversion date; provided, however, that the person in whose name any shares of our common stock shall be issuable upon such conversion will be treated as the holder of record of such shares as of the close of business on the conversion date (in the case of physical settlement) or the last trading day of the relevant observation period (in the case of combination settlement).

Exchange in Lieu of Conversion

When a holder surrenders its notes for conversion, we may, at our election (an “exchange election”), direct the conversion agent to deliver, on or prior to the trading day immediately following the conversion date, such notes to one or more financial institutions designated by us for exchange in lieu of conversion. In order to accept

S-53

any notes surrendered for conversion, the designated financial institution(s) must agree to timely pay or deliver, as the case may be, in exchange for such notes, cash, shares of our common stock, or a combination of cash and shares of our common stock, at our election, that would otherwise be due upon conversion as described above under the caption “—Conversion Rights—Settlement upon Conversion” or such other amount agreed to by the holder and the designated financial institution(s) (the “conversion consideration”). If we make an exchange election, we will, by the close of business on the trading day following the relevant conversion date, notify in writing the trustee, the conversion agent (if other than the trustee) and the holder surrendering its notes for conversion that we have made the exchange election, and we will notify the designated financial institution(s) of the relevant deadline for delivery of the consideration due upon conversion and the type of conversion consideration to be paid and/or delivered, as the case may be.

Any notes delivered to the designated financial institution(s) will remain outstanding, subject to applicable DTC procedures. If the financial institution(s) agree(s) to accept any notes for exchange but does not timely pay and/or deliver, as the case may be, the related conversion consideration, or if such designated financial institution does not accept the notes for exchange, we will pay and/or deliver, as the case may be, the relevant conversion consideration, as, and at the time, required pursuant to the indenture as if we had not made the exchange election.

Our designation of any financial institution(s) to which the notes may be submitted for exchange does not require such financial institution(s) to accept any notes.

Conversion Rate Adjustments

The conversion rate will be adjusted as described below, except that we will not make any adjustments to the conversion rate if holders of the notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of our common stock and solely as a result of holding the notes, in any of the transactions described below without having to convert their notes as if they held a number of shares of common stock equal to the conversion rate, multiplied by the principal amount (expressed in thousands) of notes held by such holder.

(1) If we exclusively issue shares of our common stock as a dividend or distribution on shares of our common stock, or if we effect a share split or share combination, the conversion rate will be adjusted based on the following formula:

LOGO

where,

CR₀ =

the conversion rate in effect immediately prior to the open of business on the ex-dividend date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or share combination, as applicable;

CR₁ =

the conversion rate in effect immediately after the open of business on such ex-dividend date or effective date;

OS₀ =

the number of shares of our common stock outstanding immediately prior to the open of business on such ex-dividend date or effective date (before giving effect to any such dividend, distribution, split or combination); and

OS₁ =

the number of shares of our common stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination.

Any adjustment made under this clause (1) shall become effective immediately after the open of business on the ex-dividend date for such dividend or distribution, or immediately after the open of business on the effective

S-54

date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, the conversion rate shall be immediately readjusted, effective as of the date our board of directors or a committee thereof determines not to pay such dividend or distribution, to the conversion rate that would then be in effect if such dividend or distribution had not been declared.

(2) If we distribute to all or substantially all holders of our common stock any rights, options or warrants (other than pursuant to a stockholder rights plan) entitling them, for a period of not more than 60 calendar days after the announcement date of such distribution, to subscribe for or purchase shares of our common stock at a price per share that is less than the average of the last reported sale prices of our common stock for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the date of announcement of such distribution, the conversion rate will be increased based on the following formula:

LOGO

where,

CR₀ =

the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such distribution;

CR₁ =

the conversion rate in effect immediately after the open of business on such ex-dividend date;

OS₀ =

the number of shares of our common stock outstanding immediately prior to the open of business on such ex-dividend date;

X =	the total number of shares of our common stock distributable pursuant to such rights, options or warrants; and

Y =

the number of shares of our common stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average of the last reported sale prices of our common stock over the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the date of announcement of the distribution of such rights, options or warrants.

Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the open of business on the ex-dividend date for such distribution. To the extent that shares of common stock are not delivered after the expiration of such rights, options or warrants, the conversion rate shall be decreased to the conversion rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of common stock actually delivered. If such rights, options or warrants are not so distributed, the conversion rate shall be decreased to the conversion rate that would then be in effect if such ex-dividend date for such distribution had not occurred.

For the purpose of this clause (2), and for the purpose of the first bullet point under the caption “—Certain Distributions Notice,” in determining whether any rights, options or warrants entitle the holders of our common stock to subscribe for or purchase shares of our common stock at a price per share that is less than such average of the last reported sale prices for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the date of announcement of such distribution, and in determining the aggregate offering price of such shares of common stock, there shall be taken into account any consideration received by us for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by us in good faith.

(3) If we distribute shares of our capital stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our capital stock or other securities, to all or substantially all holders of our common stock, excluding:

•

dividends, distributions or issuances (including share splits) as to which an adjustment was effected (or would have been effected but for the 1% exception (as defined below)) pursuant to clause (1) or (2) above;

•

except as otherwise described below, rights issued pursuant to any stockholder rights plan of ours then in effect;

•

distributions of reference property issued in exchange for, or upon conversion of, our common stock as described under the caption “—Recapitalizations, Reclassifications and Changes of Our Common Stock”;

•

dividends or distributions paid exclusively in cash as to which the provisions set forth in clause (4) below shall apply; and

•

spin-offs as to which the provisions set forth below in this clause (3) shall apply; then the conversion rate will be increased based on the following formula:

where,

CR₀ =

the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such distribution;

CR₁ =

the conversion rate in effect immediately after the open of business on such ex-dividend date;

SP₀ =

the average of the last reported sale prices of our common stock over the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the ex-dividend date for such distribution; and

FMV =

the fair market value (as determined by us in good faith) of the shares of capital stock, evidences of indebtedness, assets, property, rights, options or warrants distributed with respect to each outstanding share of our common stock on the ex-dividend date for such distribution.

Any increase made under the portion of this clause (3) above will become effective immediately after the open of business on the ex-dividend date for such distribution. If such distribution is not so paid or made, the conversion rate shall be decreased to be the conversion rate that would then be in effect if such distribution had not been declared. Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than “SP₀” (as defined above), in lieu of the foregoing increase, each holder of a note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of our common stock, the amount and kind of our capital stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our capital stock or other securities that such holder would have received if such holder owned a number of shares of common stock equal to the conversion rate in effect on the ex-dividend date for the distribution.

With respect to an adjustment pursuant to this clause (3) where there has been a payment of a dividend or other distribution on our common stock of shares of capital stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange, which we refer to as a “spin-off,” the conversion rate will be increased based on the following formula:

where,

CR₀ =

the conversion rate in effect immediately prior to the end of the “valuation period” (as defined below);

CR₁ =

the conversion rate in effect immediately after the end of the valuation period;

FMV₀ =

the average of the last reported sale prices of the capital stock or similar equity interest distributed to holders of our common stock applicable to one share of our common stock (determined by reference to the definition of last reported sale price set forth under the caption “—Optional Redemption” as if references therein to our common stock were to such capital stock or similar equity interest) over the first 10 cons
