Revenue increased 7% sequentially due to strong customer demand and improved pricing
Net income increased 41% sequentially
Adjusted EBITDA increased 20% sequentially

Industrial & Specialty Products segment contribution margin increased 7% sequentially
Amended and restated $1.1 billion Credit Agreement and extinguished $109 million of debt in March

KATY, Texas, April 27, 2023 /PRNewswire/ -- U.S. Silica Holdings, Inc. (NYSE:SLCA) (the "Company"), a diversified industrial minerals company and the leading last-mile logistics provider to the oil and gas industry, today announced net income of $44.6 million, or $0.57 per diluted share, for the first quarter ended March 31, 2023. The first quarter results were impacted by $7.0 million pre-tax, or $0.07 per diluted share after-tax, of charges primarily related to the loss on extinguishment of debt and business optimization costs, resulting in adjusted EPS (a non-GAAP measure) of $0.64 per diluted share.

These results compared with a net income of $31.6 million, or $0.40 per diluted share, for the fourth quarter of 2022, which were impacted by $2.7 million pre-tax, or $0.03 per diluted share after-tax, of charges primarily related to merger and acquisition related expenses and business optimization costs, partially offset by the gain on extinguishment of debt, resulting in adjusted EPS (a non-GAAP measure) of $0.43 per diluted share.

Bryan Shinn, Chief Executive Officer, commented, "We delivered exceptional results in the first quarter, reporting record Adjusted EBITDA and the highest level of total contribution margin dollars since 2018. Customer demand in our Oil and Gas segment remained robust and we improved pricing and expanded margins. Our Industrial and Specialty Products segment profitability increased 13% on a year-over-year basis through price increases and greater sales of higher-margin products. We also successfully entered into a new $1.1 billion Credit Agreement in the first quarter and concurrently extinguished $109 million of debt, further strengthening our balance sheet.

We expect to remain effectively sold out for sand proppant in 2023 supported by robust contractual commitments at 84% of production capacity. Our SandBox last mile logistics offering is also in strong demand and poised for another year of record profitability. In our Industrial and Specialty Products segment, we are commercializing new products, realizing benefits from structural cost reductions and price increases and continuing to sign favorable long-term contracts.

Based on the strength of our business so far this year, coupled with the visibility provided by our customer contracts and market feedback, we are raising our guidance and now expect 2023 company Adjusted EBITDA to increase 25% to 30% sequentially with associated free cash flow generation in excess of $200 million."

Outlook and Guidance

Looking forward to the second quarter, the Company's two business segments remain well positioned in their respective markets. The Company has a strong portfolio of industrial and specialty products that serve numerous essential, high growth and attractive end markets, supported by a robust pipeline of new products under development. The Company also expects growth in its underlying base business, coupled with pricing increases and surcharges to continue to fight inflationary impacts.

The oil and gas industry is progressing through a multi-year growth cycle. Constructive customer sentiment and strength in WTI crude oil prices are supportive of an active well completions environment in 2023.

The Company remains focused on generating free cash flow and de-levering the balance sheet. It expects to produce significant operating cash flow in 2023, and projects investing at the high-end of capital expenditures guidance of $50-$60 million for the year.

Forward-looking Statements

This first quarter 2023 earnings release, as well as other statements we make, contain "forward-looking statements" within the meaning of the federal securities laws - that is, statements about the future, not about past events. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. These statements may include words such as "anticipate," "estimate," "expect," "project," "plan," "intend," "believe," "may," "will," "should," "could," "can have," "likely" and other words and terms of similar meaning.

Forward-looking statements are based on our current expectations and assumptions, which may not prove to be accurate. These statements are not guarantees and are subject to risks, uncertainties and changes in circumstances that are difficult to predict. Many factors could cause actual results to differ materially and adversely from these forward-looking statements. Among these factors are global economic conditions; heightened levels of inflation and rising interest rates; supply chain and logistics constraints for our company and our customers, fluctuations in demand for commercial silica, diatomaceous earth, perlite, clay and cellulose; fluctuations in demand for frac sand or the development of either effective alternative proppants or new processes to replace hydraulic fracturing; the entry of competitors into our marketplace; changes in production spending by companies in the oil and gas industry and changes in the level of oil and natural gas exploration and development; changes in oil and gas inventories; general economic, political and business conditions in key regions of the world including the ongoing conflict between Russia and Ukraine; the effect of the COVID-19 pandemic on markets the Company serves; pricing pressure; cost inflation; weather and seasonal factors; the cyclical nature of our customers' business; our inability to meet our financial and performance targets and other forecasts or expectations; our substantial indebtedness and pension obligations, including restrictions on our operations imposed by our indebtedness; operational modifications, delays or cancellations; prices for electricity, natural gas and diesel fuel; our ability to maintain our transportation network; changes in government regulations and regulatory requirements, including those related to mining, explosives, chemicals, and oil and gas production; silica-related health issues and corresponding litigation; and other risks and uncertainties detailed in this press release and our most recent Forms 10-K, 10-Q, and 8-K filed with or furnished to the U.S. Securities and Exchange Commission. If one or more of these or other risks or uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions prove incorrect, actual outcomes may vary materially from those reflected in our forward-looking statements. The forward-looking statements speak only as of the date hereof, and we disclaim any intention or obligation to update publicly or revise such statements, whether as a result of new information, future events or otherwise.

Non-GAAP Financial Measures

Segment Contribution Margin

Segment contribution margin is a key metric that management uses to evaluate our operating performance and to determine resource allocation between segments. Segment contribution margin excludes selling, general, and administrative costs, corporate costs, plant capacity expenses, and facility closure costs.

The following table sets forth a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to segment contribution margin.

(All amounts in thousands)	Three Months Ended

Adjusted EBITDA

Adjusted EBITDA is not a measure of our financial performance or liquidity under GAAP and should not be considered as an alternative to net income (loss) as a measure of operating performance, cash flows from operating activities as a measure of liquidity or any other performance measure derived in accordance with GAAP. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management's discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements. Adjusted EBITDA contains certain other limitations, including the failure to reflect our cash expenditures, cash requirements for working capital needs and cash costs to replace assets being depreciated and amortized, and excludes certain charges that may recur in the future. Management compensates for these limitations by relying primarily on our GAAP results and by using Adjusted EBITDA only supplementally. Our measure of Adjusted EBITDA is not necessarily comparable to other similarly titled captions of other companies due to potential inconsistencies in the methods of calculation.

The following table sets forth a reconciliation of net income (loss), the most directly comparable GAAP financial measure, to Adjusted EBITDA:

₍₁₎	Reflects equity-based and other equity-related compensation expense.
₍₂₎	Includes net pension cost and net post-retirement cost relating to pension and other post-retirement benefit obligations during the applicable period, but in each case excluding the service cost relating to benefits earned during such period. Non-service net periodic benefit costs are not considered reflective of our operating performance because these costs do not exclusively originate from employee services during the applicable period and may experience periodic fluctuations as a result of changes in non-operating factors, including changes in discount rates, changes in expected returns on benefit plan assets, and other demographic actuarial assumptions.
₍₃₎	Merger and acquisition related expenses include legal fees, professional fees, bank fees, severance costs, and other employee related costs. While these costs are not operational in nature and are not expected to continue for any singular transaction on an ongoing basis, similar types of costs, expenses and charges have occurred in prior periods and may recur in the future as we continue to integrate prior acquisitions and pursue any future acquisitions.
₍₄₎	Plant capacity expansion expenses include expenses that are not inventoriable or capitalizable as related to plant expansion projects greater than $5 million in capital expenditures or plant start up projects. While these expenses are not operational in nature and are not expected to continue for any singular project on an ongoing basis, similar types of expenses have occurred in prior periods and may recur in the future if we continue to pursue future plant capacity expansion.
₍₅₎	Reflects contract termination expenses related to strategically exiting a supplier service contract. While these expenses are not operational in nature and are not expected to continue for any singular event on an ongoing basis, similar types of expenses have occurred in prior periods and may recur in the future as we continue to strategically evaluate our contracts.
₍₆₎	Reflects costs incurred related to business optimization projects within our corporate center, which aim to measure and improve the efficiency, productivity and performance of our organization. While these costs are not operational in nature and are not expected to continue for any singular project on an ongoing basis, similar types of expenses may recur in the future.
₍₇₎	Reflects costs incurred related to idled sand facilities and closed corporate offices, including severance costs and remaining contracted costs such as office lease costs, maintenance, and utilities. While these costs are not operational in nature and are not expected to continue for any singular event on an ongoing basis, similar types of expenses may recur in the future.
₍₈₎	Reflects miscellaneous adjustments permitted under the Credit Agreement, such as recruiting fees and relocation costs. The three months ended March 31, 2023 also included costs related to severance restructuring of $0.8 million, an adjustment to non-controlling interest of $0.2 million and $5.3 million related to the loss on extinguishment of debt, offset by an insurance recovery of $0.8 million. The three months ended December 31, 2022 also included restructuring severance of $0.8 million and an adjustment to non-controlling interest of $0.2 million, offset by the gain on extinguishment of debt of $1.2 million. The three months ended March 31, 2022 also included costs related to weather events and supplier and logistical issues of $0.8 million, severance restructuring of $0.1 million, an adjustment to non-controlling interest of $0.1 million, partially offset by proceeds of the sale of assets of $0.5 million.

Forward-looking Non-GAAP Measures

A reconciliation of Adjusted EBITDA and free cash flow generation as used in our guidance, each of which is a forward-looking non-GAAP financial measure, to the most directly comparable GAAP financial measure, is not provided because the Company is unable to provide such reconciliation without unreasonable effort. The inability to provide each reconciliation is due to the unpredictability of the amounts and timing of events affecting the items we exclude from the non-GAAP measure.
