KATY, Texas, Feb. 27, 2024 /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 its fourth quarter and full year results for the period ended December 31, 2023.

"During the fourth quarter, we continued to strengthen our financial foundation and advance our growth strategy while closing out an exceptionally strong and historic year for the company," said Bryan Shinn, U.S. Silica's Chief Executive Officer. "In 2023, we delivered on our guidance of approximately 25% year-over-year improvement in Adjusted EBITDA, generated another year of robust cash flow from operations of $264 million, managed an 88% increase in annual net income, and improved our total company contribution margin by 16% year-over-year. These impressive annual results were driven by healthy customer demand, disciplined pricing in our Oil and Gas segment, and increased pricing and improved product mix for our Industrial and Specialty Products segment, all of which was supported by our optimized and lean cost structure. Furthermore, in the fourth quarter, we repurchased and extinguished an additional $25 million of debt, improving our balance sheet and maintaining a low net leverage ratio of 1.4x.

"In our Oil and Gas segment, thanks to our disciplined pricing approach, coupled with our variable cost reduction initiatives, we delivered a strong segment contribution margin of 35% for the quarter despite the demand impact of lower drilling and completions activity due to weather and fourth-quarter seasonality. In the fourth quarter, we signed four customer contract amendments and extensions, reflecting our stellar market reputation for reliability and ability to deliver proppant at scale. Additionally, our new, patent-pending Guardian frac fluid filtration system continues to perform well and gain momentum in the market, and we expect to add several incremental systems to the fleet in 2024.

"In our Industrial and Specialty Products segment, we benefited from ongoing structural cost reductions, price increases, and greater sales from advanced materials, resulting in improved profitability with a 27% increase in contribution margin on a per ton basis when compared to the prior year quarter. As expected, however, our fourth quarter volumes declined on a year-over-year basis, due to a combination of normal reduced seasonal demand, customer facility maintenance, and customer year-end inventory management.

"Looking ahead, 2024 is shaping up to be another strong year of operating cash flow generation. Our Oil and Gas segment is well positioned in active well completion basins, with strong customer commitments that provide cash flow visibility. In our Industrial segment, customer demand remains strong overall, and we anticipate year-over-year improvements as we realize a full quarter of price increases."

Fourth Quarter 2023 Highlights

Net income for the fourth quarter ended December 31, 2023 was $29.1 million, or $0.37 per diluted share. The fourth quarter results were impacted by $9.1 million pre-tax, or $0.09 per diluted share after-tax, of gains primarily related to asset sales, partially offset by facility closure costs, business optimization, and the loss on extinguishment of debt, resulting in adjusted EPS (a non-GAAP measure) of $0.28 per diluted share.

These results compared with net income of $26.9 million, or $0.34 per diluted share, for the third quarter of 2023, which was impacted by $3.8 million pre-tax, or $0.04 per diluted share after-tax, of charges primarily related to a non-recurring adjustment to depreciation and the loss on extinguishment of debt, resulting in adjusted EPS (a non-GAAP measure) of $0.38 per diluted share.

In the fourth quarter of 2023, the Company completed a $25 million voluntary term loan principal repayment, extinguishing the debt at par using excess cash on hand.

Oil & Gas Segment

Fourth quarter 2023 results were driven by lower proppant volumes, fewer SandBox loads, and a decrease in average selling price per ton.

Capital Update

As of December 31, 2023, the Company had $245.7 million in cash and cash equivalents and total debt was $840.0 million. The Company's $150.0 million Revolver had zero drawn, with $15.3 million allocated for letters of credit, and availability of $134.7 million. Capital expenditures in 2023 totaled $65.2 million and were primarily related to growth projects, facility improvements, and maintenance projects. During 2023, the Company generated $263.9 million in cash flow from operations.

Reclassification of Northern White Sand Offerings

After careful consideration, the Company is reallocating its Northern White Sand offerings from the Oil and Gas business segment to the Industrial and Specialty Products segment beginning with first quarter 2024 results. Given how the Northern White Sand business has evolved over the years, the Company believes that it is better positioned today as an offering within ISP. This change will streamline U.S. Silica's business operations and allow the Company to maximize value as it will now have all Northern White Sand based offerings in one business unit. Management will discuss this reclassification further on its first-quarter 2024 earnings call and offer historical examples to bridge prior quarter results to the new reporting design.

Outlook and Guidance

"Looking ahead to the first quarter of 2024, our two business segments remain well positioned in their respective markets," said Shinn. "U.S. Silica 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. We expect growth in our underlying base business, coupled with pricing increases and total addressable market expansions.

"The oil and gas industry continues to progress through a multi-year growth cycle. Constructive through-cycle commodity prices coupled with improved well completion efficiencies and intensity are supportive of an active environment over the next few years, and we have strong contractual commitments for our sand production capacity for the year.

"We remain focused on generating cash flow from operations and de-levering the balance sheet. We expect to produce robust operating cash flow in 2024, while investing approximately $60 million for capital expenditures for the year."

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 expansion expenses, and facility closure costs. We believe that segment contribution margin, as defined above, is an appropriate measure for evaluating the operating performance of our segments. However, segment contribution margin is a non-GAAP measure and should be considered in addition to, not a substitute for, or superior to, net income (loss) or other measures of financial performance prepared in accordance with GAAP.

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 available 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. Trailing Twelve Month (TTM) Adjusted EBITDA is a measure of Adjusted EBITDA over the trailing twelve months.

₍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 $2 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₎	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.
₍₇₎	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.
₍₈₎	Reflects miscellaneous adjustments permitted under the Credit Agreement. The year ended December 31, 2023 also included costs related to severance restructuring of $0.9 million, recruiting costs of $1.5 million, an adjustment to non-controlling interest of $0.4 million and $8.5 million related to the loss on extinguishment of debt, offset by an insurance recovery of $0.6 million and net proceeds of the sale of assets of $18.6 million. 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.

Adjusted EPS

Adjusted EPS is diluted earnings or loss per share adjusted to exclude costs associated with merger & acquisition related activities and strategic business reviews, costs associated with business optimization, facility closure costs, asset gain or loss, the effect of a non-recurring depreciation adjustment, and gain or loss on debt extinguishment.

Management believes Adjusted EPS is useful in providing period-to-period comparisons of the results of the Company's operations to assist investors in reviewing the Company's operating performance over time. Management believes it is useful to exclude certain items when comparing current performance to prior periods because these items can vary significantly depending on specific underlying transactions or events. Also, management believes certain excluded items may not relate specifically to current operating trends or be indicative of future results.

The following table sets forth a reconciliation from GAAP EPS to adjusted EPS:

	Three Months Ended

Adjusted Diluted EPS	$ 0.28	$ 0.38	$ 0.43

Diluted Shares	78,799	78,700	78,026

Free Cash Flow

Free Cash Flow is a non-GAAP financial measure which is calculated as net cash provided by operating activities less capital expenditures. Management believes that Free Cash Flow is a measure to assess liquidity of the business.

The following table sets forth a reconciliation of cash flows from operating activities to free cash flow:

(All amounts in thousands)	Year Ended		Three Months Ended
	December 31, 2023	December 31, 2022	December 31, 2023
Net cash provided by operating activities	$ 263,868	$ 262,716	$ 54,160
Capital expenditures	(65,155)	(53,168)	(17,529)
Free cash flow	$ 198,713	$ 209,548	$ 36,631

Net Debt

Net Debt is calculated by adding together the current portion of long-term debt and long-term debt, net and subtracting cash and cash equivalents from the total. Net debt shows how a company's indebtedness has changed over a period as a result of cash flows. Net debt allows investors to see how business financing has changed and assess whether an entity that has had a significant increase in cash has, for example, achieved this only by taking on a corresponding increase in debt. Net debt 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.

Net Leverage Ratio

Net Leverage Ratio is calculated by dividing net debt by Trailing Twelve Month (TTM) Adjusted EBITDA. Management believes that net leverage ratio provides useful information to investors because it is an important indicator of the Company's indebtedness in relation to its operating performance. Net Leverage Ratio should be considered in addition to results prepared in accordance with GAAP and should not be considered substitutes for or superior to GAAP results. In addition, our Net Leverage Ratio may not be comparable to similarly titled measures utilized by other companies.

The following table sets forth a reconciliation for net debt and net leverage ratio:

	Year Ended	Three Months Ended
(All amounts in thousands)	December 31, 2022	March 31, 2023	June 30, 2023	September 30, 2023	December 31, 2023
Cash and cash equivalents	$ (280,845)	$ (139,494)	$ (186,961)	$ (222,435)	$ (245,716)
Current portion of long-term debt	19,535	13,590	10,152	19,763	16,367
Long-term debt	1,037,458	897,013	871,913	847,849	823,670
Net debt	$ 776,148	$ 771,109	$ 695,104	$ 645,177	$ 594,321

TTM Adjusted EBITDA	$ 353,558	$ 425,291	$ 455,142	$ 454,565	$ 439,000
Net Leverage Ratio	2.2x	1.8x	1.5x	1.4x	1.4x

Forward-looking Non-GAAP Measures

A reconciliation of net leverage ratio and segment contribution margin as used in our guidance, which are forward-looking non-GAAP financial measures, to the most directly comparable GAAP financial measure, is not provided because the Company is unable to provide such reconciliations 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 measures.
