News Release
U.S. Silica Holdings, Inc. Announces Fourth Quarter and Full Year 2022 Results
Fourth quarter revenue of $412.9 million and full year revenue of $1.5 billion
GAAP and adjusted EPS for the quarter of $0.40 and $0.43 per diluted share, respectively
Full year 2022 cash flow from operations of $262.7 million increased 55% year-over-year
Oil & Gas proppant volumes increased 2% and SandBox loads increased 3% sequentially
Oil & Gas segment contribution margin increased 11% sequentially

Katy, Texas, February 24, 2023 – U.S. Silica Holdings, Inc. (NYSE: SLCA) today announced net income of $31.6 million, or $0.40 per diluted share, for the fourth quarter ended December 31, 2022. The fourth quarter results 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 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.
These results compared with net income of $32.1 million, or $0.41 per diluted share, for the third quarter of 2022, which were negatively impacted by $2.1 million pre-tax, or $0.02 per diluted share after-tax, primarily related to merger and acquisition related expenses and optimization costs, partially offset by the gain on extinguishment of debt.
Bryan Shinn, Chief Executive Officer, stated, “Our fourth quarter delivered a strong close to an exceptional year. During 2022, we successfully executed our strategic plan and delivered impressive bottom-line results while strengthening our balance sheet and positioning U.S. Silica for future success. In 2022, we significantly raised pricing across both segments to help offset inflation, we increased contract coverage while expanding margins in our Oil and Gas segment, and generated $262.7 million of cash flow from operations. We opportunistically used this cash to retire $150 million of long-term debt, effectively reducing our net leverage ratio to 2.2x at year-end. Financially and operationally, we reported impressive achievements during the year, as revenues increased 38%, Adjusted EBITDA grew 58%, and overall tons sold increased 14% year-over-year.
“In our Oil and Gas segment, activity was strong through the holidays, and we did not experience meaningful disruptions from seasonality or weather. The supply and demand balance remained very tight in sand proppant and last-mile logistics, and we continued to be effectively sold-out due to strong well completion demand, especially in West Texas. During the quarter, our customers secured incremental sand supply for the medium term and we signed attractive multi-year contracts that extend into 2024 and 2025, in addition to successfully realizing increased pricing on existing customer contracts.
"In our Industrial and Specialty Products segment, our fourth quarter profitability declined sequentially as we’d expected, due to normal year-end seasonality. Partially offsetting these seasonal impacts, were lower natural gas input costs and the previously announced November 1st price increases on most of our non-contracted industrial products.
"In summary, 2023 is setting up to be another strong year of financial performance and free cash flow generation. Our Oil and Gas segment is well positioned to continue to generate strong earnings and cash flow while delivering further sequential growth. In our Industrial segment, customer demand remains strong overall, and we anticipate sequential improvements as customer activity rebounds from the typical fourth quarter seasonality and we realize a full quarter of price increases.”

As of December 31, 2022, the Company had $280.8 million in cash and cash equivalents and total debt was $1.057 billion.

During 2022, the Company generated $262.7 million in cash flow from operations.
Outlook and Guidance
Looking forward to the first quarter and into 2023, 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 and intends on being operating cash flow positive in 2023, keeping an estimated $50-$60 million of capital expenditures within operating cash flow.

Forward-looking Statements
This full-year and fourth-quarter 2022 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 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; the effect of the COVID-19 pandemic on markets the Company serves; 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; pricing pressure; 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 certain corporate costs not associated with the operations of the segment. These unallocated costs include costs related to corporate functional areas such as sales, production and engineering, corporate purchasing, accounting, treasury, information technology, legal and human resources.
The following table sets forth a reconciliation of net income, the most directly comparable GAAP financial measure, to segment contribution margin.

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 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 non-recurring 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.

(1)
Reflects equity-based non-cash 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.
(5)
Reflects contract termination expenses related to strategically exiting a 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)
No impairment charges were recorded for the year ended December 31, 2022. Impairment charges of $202 thousand were recorded for the year ended December 31, 2021.
(7)
Reflects costs incurred related to business optimization projects mainly 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.
(8)
Reflects costs incurred mainly related to idled sand facilities and closed corporate offices, including severance costs and remaining contracted costs such as office lease costs, and common area maintenance fees. 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.
(9)
Gain on valuation change of royalty note payable due to a change in estimate of future tonnages and sales related to the sand shipped from our Tyler, Texas facility. This gain is not operational in nature and is not expected to continue for any singular event on an ongoing basis.
(10)
Reflects miscellaneous adjustments permitted under the Credit Agreement. The year ended December 31, 2022 also included costs related to weather events and supplier and logistical issues of $1.1 million, severance restructuring costs of $1.8 million, an adjustment to non-controlling interest of $0.6 million, partially offset by net proceeds of the sale of assets of $1.7 million and $2.9 million related to the gain on extinguishment of debt. The year ended December 31, 2021 also included $3.4 million of transload shortfall and exit fees, $2.1 million related to expenses incurred with severe winter storms during the first quarter, $0.7 million of costs related to a power interruption at a plant location, partially offset by $0.1 million for a measurement period adjustment related to the Arrows Up bargain purchase.
