SPX Retirement Savings and Stock Ownership Plan

Charlotte, North Carolina

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the SPX Retirement Savings and Stock Ownership Plan (the “Plan”) as of December 31, 2025 and 2024, the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and the related notes (collectively, the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2025 and 2024, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risk of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by the Plan’s management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2025 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is presented for the purpose of additional analysis and is not a required part of the financial statements but included supplemental information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The

supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

SPX Retirement Savings and

Stock Ownership Plan

Notes to Financial Statements

December 31, 2025 and 2024

Note 1 - Description of the Plan

The following description of the SPX Retirement Savings and Stock Ownership Plan (the “Plan”), as amended and restated effective January 1, 2023, provides only general information. Participants should refer to the Plan document for a complete description of the Plan’s provisions. The Plan became effective January 1, 1952 and is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

General - The Plan is a defined contribution plan that benefits employees of SPX Technologies, Inc. (“SPX,” the “Employer,” or the “Company”) who have met eligibility requirements. The Plan sponsor, SPX Enterprises, LLC, is a direct subsidiary of SPX.

Contributions - Participants can elect to defer a portion of their compensation as pre-tax contributions or Roth contributions in the Plan, up to the maximum allowed under the Plan and the Internal Revenue Code (“Code”).

As outlined in the Plan document, employer contributions are dependent upon the business unit or division of the Company where the participant is employed. In general, for participants other than those related to certain plans that have been previously merged into the Plan, the Company makes matching contributions equal to 100 percent of the participant’s pre-tax and Roth contributions up to the first 4 percent of compensation deferred and 50 percent of the participant’s pre-tax and Roth contributions in excess of 4 percent of compensation deferred up to a maximum of 6 percent of compensation deferred.

Effective January 1, 2025, the Plan implemented automatic enrollment for all newly eligible employees, with an initial default contribution of 3 percent of eligible compensation with an automatic increase to the default contribution rate of 0.5 percent annually until reaching a maximum of 6 percent. Employees may opt-out of the enrollment and automatic annual increase at any time.

Employer contributions are in the form of SPX Technologies, Inc. common stock, are immediately vested and can be transferred to other investment options at any time, subject to certain trading restrictions.

Employer contributions for participants related to certain plans that have been previously merged into the Plan are determined based on the respective collective bargaining agreements.

Participant Accounts - Each participant’s account is credited with the participant’s contributions, the Employer’s contributions, if any, and an allocation of Plan earnings.

Notes to Financial Statements

December 31, 2025 and 2024

Note 1 - Description of the Plan (Continued)

Allocation of Plan earnings to participant accounts is based on the participant’s proportionate share of funds in each of the investment accounts. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s account.

Participants elect to invest their account balances and contributions among various investment options selected by the SPX Retirement and Welfare Plan Administrative Committee (the “Committee”), including an option to invest in SPX Technologies, Inc. common stock.

Vesting - Participants in the Plan are at all times 100 percent vested in their contributions and earnings thereon. Vesting in employer contributions is dependent upon the business unit or division of the Company where the participant is employed. In general, participants are 100 percent vested in employer contributions; however, there are certain employer contributions that vest over a three to six years period. Any forfeitures may be used to pay expenses of the Plan or reduce the employer contributions in the year the forfeitures occur or in future years. During 2025, forfeitures were used to pay expenses of the Plan.

Payment of Benefits - Upon termination of service, a participant may elect to receive either a lump-sum distribution or monthly or yearly payments equal to the value of their account. Terminated participants with account balances in excess of $7,000 can also elect to wait until retirement age to receive benefits. A participant who experiences a financial hardship is eligible to receive a distribution from their plan account. The Plan also allows participants to withdraw certain portions of their balances attributed to certain benefit plans that have been previously merged into the Plan. All withdrawal payments are made by Fidelity Management Trust Company (the “Trustee” or “Fidelity”).

Employer Securities - Investment in SPX Technologies, Inc. stock transferred to participants’ accounts by reason of the merger of the SPX Stock Ownership Plan on January 1, 1994 and stock allocated to participants’ accounts by reason of matching contributions as discussed above can be redirected to other investment options, subject to certain trading restrictions.

Notes Receivable from Participants - A participant can borrow from the Plan an amount not to exceed the lesser of $50,000 or 50 percent of the participant’s vested account balance. The term of the note receivable from participants may not exceed five years unless used in the purchase of a primary residence, in which case the term may be up to 15 years.

Notes receivable from participants are collateralized by the balance in the participant’s account and bear interest at market rates as outlined in the Plan document. Principal and interest are paid ratably through payroll deductions. Other notes receivable from participants provisions are outlined in the Plan document.

December 31, 2025 and 2024

Note 1 - Description of the Plan (Continued)

Voting Rights - Each participant is entitled to exercise voting rights attributable to the shares of SPX Technologies, Inc. common stock allocated to their account. The Trustee is required to vote shares of common stock that have been allocated to participants, but for which the Trustee received no voting instructions, in the same manner and in the same proportion as the shares for which the Trustee received timely voting instructions.

Administration - SPX Enterprises, LLC is the sponsor of the Plan. The Committee, as provided in the Plan document, is the plan administrator. The Trustee also functions as the investment manager.

Investment management fees and trustee fees are paid by the Plan in accordance with the Plan document.

Party-in-interest Transactions - Certain plan assets are in investment funds managed by Fidelity or its affiliates. Fidelity is the custodian of the Plan and, therefore, these transactions qualify as party-in-interest transactions as defined under ERISA guidelines. The Plan also issues loans to participants which are secured by the vested balance of the participants' accounts. For the year ended December 31, 2025, transactions involving SPX Technologies, Inc. common stock included sales of approximately $26,000,000.

Termination - Although it has not expressed any intent to do so, the Company has the right to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. Upon termination of the Plan, participants become fully vested in their account balances.

Note 2 - Summary of Significant Accounting Policies

Basis of Accounting - The accompanying financial statements of the Plan are prepared on the accrual basis of accounting.

Notes Receivable from Participants - Notes receivable from participants are recorded at their unpaid principal balances plus any accrued interest. Notes receivable from participants are written off when deemed uncollectible.

Investments - The Plan’s investments are stated at fair value. Common collective trust fund investments are valued at net asset value per share (“NAV”), which is based on the fair value of the underlying assets. There are no unfunded commitments or other redemption notice requirements related to these investments. All other investments are valued based on quoted market prices. See Note 4 for additional information. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Net appreciation in the fair value of investments includes the Plan's gains and losses on investments bought and sold as well as held during the year. Dividend income is accrued on the ex-dividend date.

Notes to Financial Statements

December 31, 2025 and 2024

Note 2 - Summary of Significant Accounting Policies (Continued)

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

Benefit Payments - Distributions to participants are recorded when paid.

Income Tax Status - The Plan constitutes a qualified plan under Sections 401(a) and 401(k) of the Code and the related trust is exempt from federal income tax under Section 501(a) of the Code. The Plan obtained its determination letter dated May 3, 2017, in which the Internal Revenue Service stated that the Plan, as designed, was in compliance with the applicable requirements of the Code. Although the Plan has been amended subsequently, the plan administrator believes the Plan is being operated in compliance with the applicable requirements of the Code. Therefore, no provision for income taxes has been included in the Plan’s financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no Internal Revenue Service examinations for any tax periods in progress.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of additions and deductions during the reporting period. Actual results could differ from those estimates.

Risks and Uncertainties - The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statement of net assets available for benefits.

The Plan’s investments include shares of SPX Technologies, Inc. common stock, which represent a concentration of investments in securities issued by the Plan sponsor. As a result, the value of these investments is subject to risks associated with the Company’s financial performance, industry conditions, and overall market volatility.

Participants may direct their investments among the Plan’s available options and may transfer amounts invested in SPX Technologies, Inc. common stock into other investment alternatives, subject to certain trading restrictions. However, participant investment decisions may result in a continued concentration in employer securities.

Note 2 - Summary of Significant Accounting Policies (Continued)

Accordingly, it is at least reasonably possible that changes in the fair value of SPX Technologies, Inc. common stock could materially affect participants’ account balances and the Plan’s net assets available for benefits.

Contributions Receivable - Participant contributions and any related matching contributions are recognized in the period during which the Company makes the respective payroll deduction for the participant's compensation.

Note 3 - Reconciliation of Financial Statements to Form 5500

The net assets on the financial statements differ from the net assets on Form 5500 due to a common collective trust fund, specifically a stable value fund, which is recorded at NAV on the financial statements and at fair value on Form 5500. The net assets on the financial statements were higher than Form 5500 by $1,696,172 and $3,583,633 at December 31, 2025 and 2024, respectively. Accordingly, the net increase in the net assets available for benefits on the financial statements is $1,887,461 lower than as reported on Form 5500 for the year ended December 31, 2025.

Note 4 - Fair Value Measurements

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

Accounting standards require certain assets and liabilities be reported at fair value in the financial statements and provide a framework for establishing that fair value. The framework for determining fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value.

The Plan utilizes market data or assumptions that it believes market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can include readily observable quoted prices in active markets for identical assets or liabilities (“Level 1”), significant other observable inputs (“Level 2”) or significant unobservable inputs (“Level 3”). The Plan’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability. In instances where inputs used to measure fair value fall into different levels in the fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest input that is significant to the valuation.

Mutual funds and money markets are valued at daily closing prices from an active market, which represents the NAV, as reported by the fund.

Stock Ownership Plan

Notes to Financial Statements

December 31, 2025 and 2024

Note 4 - Fair Value Measurements (Continued)

The SPX Technologies, Inc. common stock is tracked on a unitized basis, which consists primarily of common stock of SPX Technologies, Inc. and a money market fund that is sufficient to meet daily cash needs. The common stock is valued at daily closing prices from an active market on which the individual securities are traded.

Common collective trust funds are based as of the last day of the Plan year on the NAV share price of each respective fund. The NAV, as provided by the trustee of the common collective trust funds, is used as a practical expedient to estimate fair value. The NAV is based on the fair value of the underlying investments held by the fund that are traded in an active market, less its liabilities.

Assets measured at fair value on a recurring basis are as follows:


	Assets Measured at Fair Value at December 31, 2025
	Investments (at fair value)		Level 1		Level 2	Level 3
Mutual funds	$	252,101,862	$	252,101,862	—	—
