U.S. Silica Holdings, Inc. Announces Fourth Quarter and Full Year 2020 Results- Fourth quarter revenue of $227.3 million and full year revenue of $845.9 million- GAAP EPS earnings for the quarter of $0.06 per basic and diluted share and adjusted EPS loss ($0.26) per basic and diluted share- Industrial and Specialty Products segment volumes increased 10% versus fourth quarter 2019- Oil & Gas proppant volumes increased 48% and SandBox loads increased 71% sequentially in the fourth quarter KATY, Texas, Feb. 26, 2021

KATY, Texas, Feb. 26, 2021 /PRNewswire/ -- U.S. Silica Holdings, Inc. (NYSE: SLCA) today announced net income of $4.6 million, or $0.06 per basic and diluted share, for the fourth quarter ended December 31, 2020, compared with a net loss of $292.9 million, or $3.99 per basic and diluted share, for the fourth quarter of 2019. The fourth quarter results were negatively impacted by $4.1 million of charges related to asset impairments, facility closure costs, a plant capacity expansion, and other expenses. These charges were offset by an $8.3 million valuation change on a note payable. Additionally, the Company recorded $27.2 million of shortfall penalties in our Oil and Gas segment, resulting in adjusted EPS of ($0.26) per basic and diluted share.

"I am proud of how our company successfully navigated 2020 and of our industry leading performance during the year in spite of the challenging macro-economic environment."

"We delivered another strong financial quarter and substantially beat expectations through structural cost reductions, disciplined execution in oil and gas and a rebound in the industrial and specialty products segment."

"2021 is off to a good start with surging proppant demand and a continuing recovery in general industrial markets. We are well positioned for success this year and beyond with numerous growth opportunities in our new product pipeline across a diverse set of markets and end uses," said Bryan Shinn, U.S. Silica chief executive officer.

Outlook and Guidance

Looking ahead to 2021 and beyond, the Company is well positioned for sustainable, long-term growth by servicing critical industries such as food and beverage production, housing, automotive, glass manufacturing, biopharma, and energy. The Company has a pipeline of innovative, new products to service high growth, sustainable end uses including solar energy, wind power, cleaner air, green diesel, food safety and energy efficient buildings.

The Company continued to focus on its three strategic priorities in 2020, namely, 1) prioritizing free cash flow, 2) repositioning its Oil & Gas segment, and 3) growing its Industrial & Specialty Products segment.

The Company is focused on free cash flow and de-levering the balance sheet and intends on being cash flow positive in 2021, keeping an estimated $30-40 million of capital expenditures within operating cash flow.

Despite the continued macro-economic uncertainty, the Industrial & Specialty Products segment has proven its resiliency and is off to a good start in 2021 and growth is expected to outpace U.S. GDP.

The Company has repositioned the Oil & Gas segment by right sizing proppant capacity and reducing costs to match current and expected demand from well completions. The Company expects a robust recovery in energy sector proppant and last mile delivery demand especially in the first half of 2021 and expects the first quarter to be up 15-20% in volume sequentially, despite temporary headwinds from the unprecedented cold weather in February.

Non-GAAP Financial MeasuresSegment 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.



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[(2)] 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.



Merger and acquisition related expenses include legal fees, consulting fees, bank fees, severance costs, certain purchase accounting items, such as the amortization of inventory fair value step-up, information technology integration costs and similar charges. While these costs are[(3)] 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.



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 [(4)] 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.



Reflects contract termination expenses related to strategically exiting a service contract and losses related to sub-leases. While these [(5)] 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.



During 2020, there was an unprecedented drop in global demand combined with the breakdown of the Organization of the Petroleum Exporting Countries and other oil producing nations ("OPEC+") agreement to restrict oil production that led to one of the largest annual crude oil inventory builds in history. This led to a sharp reduction in global crude oil prices. Containment measures and other economic, travel, and business disruptions caused by COVID-19 also affected refinery activity and future demand for crude oil, and consequently, the services and products of our Oil & Gas Proppants segment. As a result, impairment charges of $11.8 million of long-lived assets, $6.8 million of inventory, $3.4 million of operating lease right-of-use assets, and $86.1 million of goodwill were recorded in our Oil & Gas Proppants segment. Additionally, $2.5 million of impairment charges were [(6)] recorded for other intangible assets in our Industrial & Specialty Products segment due to the discontinuance of a minor product line. For the fourth quarter and year ended 2019, reflects $243.1 million of long-lived asset impairments, $115.4 million of operating lease right-of-use asset impairments, $4.1 million of inventory asset impairments, and $1.2 million of intangible asset impairments in our Oil and Gas Proppants reporting segment. These impairments were related to a sharp decline in customer demand for Northern White frac sand and for regional non-in-basin frac sand as more tons are produced and sold in-basin, along with significant price decreases of frac sand. Additionally, given these events, we also experienced a significant decline in the utilization of our sand railcar fleet in our transload network leading to a significant number of rail cars being put into storage and no longer used to deliver sand to our customers.



Reflects costs incurred related to business optimization projects mainly within our corporate center, which aim to measure and improve [(7)] 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.



Reflects costs incurred mainly related to idled sand facilities and closed corporate offices, including severance costs and remaining [(8)] 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.

For 2020, includes $1.6 million in transload shortfalls and exit fees, $4.6 million in inventory adjustments, $6.0 million in severance costs, and $11.8 million in legal expense due to the unsuccessful defense of a small number of our patents, offset by $15.2 million related to the gain attributable to the bargain purchase of Arrows Up. For 2019, includes $6.2 million of loss contingencies reserve as well as restructuring costs for actions that will provide [(10)]future savings, storm damage costs, recruiting fees, relocation costs and a loss on sale of assets, partially offset by insurance proceeds of $2.2 million. While these gains and costs are not operational in nature and are not expected to continue for any singular event on an ongoing basis, similar types of gains and expenses have occurred in prior periods and may recur in the future.
