News Release

U.S. Silica Holdings, Inc. Announces Fourth Quarter and Full Year 2018 Results

• Fourth quarter revenue of $357.4 million and full year revenue of $1.58 billion

• GAAP and adjusted EPS loss for the quarter of $(3.44) and $(0.04) per share, respectively

• Returned $148.5 million to shareholders in 2018 by repurchasing more than 7.8 million shares

• Sold a record 14.2 million tons in Oil & Gas in 2018

• Record annual revenue in our Industrial and Specialty Products segment

• Ended the year with 90 SandBox crews, equating to 24% share in last-mile logistics

Katy, Texas, February 19, 2019 – U.S. Silica Holdings, Inc. (NYSE: SLCA) today announced a net loss of $256.1 million, or $(3.44) per basic and diluted share, for the fourth quarter ended December 31, 2018, compared with net income of $72.0 million, or $0.89 per basic and $0.88 per diluted share, for the fourth quarter of 2017. The fourth quarter results were negatively impacted by $265.7 million or $3.15 per share in impairment expenses, $14.0 million or $0.14 per share in costs related to plant startup and expansion expenses, $5.7 million or $0.06 per share related to merger and acquisition expenses, $2.5 million or $0.03 per share in contract termination costs and $1.9 million or $0.02 per share in other adjustments, resulting in adjusted EPS for the fourth quarter of $(0.04) per basic and diluted share.

Commenting on the Company’s fourth quarter results, U.S. Silica president and chief executive officer Bryan Shinn said, "Our Industrial and Specialty business had a very solid quarter, more than doubling contribution margin dollars on a year over year basis, driven by enhanced customer and product mix and a meaningful contribution from EP Minerals.’’ Shinn added that, "Our Oil & Gas sand proppant sales were negatively impacted by the well reported industry headwinds related to budget exhaustion and lack of takeaway capacity, as well as further pricing pressure from a combination of low demand and additional local sand capacity coming on line in the Permian. However, SandBox, our industry-leading last-mile logistics solution, had a strong finish to 2018. We ended the year with 90 crews, within the range we guided to earlier in the year. We estimate that at the end of Q4 we had approximately 24% market share based on the amount of sand moving through our equipment,’’ he concluded.

Capital Update

As of December 31, 2018, the Company had $202.5 million in cash and cash equivalents and $95.2 million available under its credit facilities. Total debt as of December 31, 2018 was $1.260 billion. Capital expenditures in the fourth quarter totaled $119.0 million and were mainly for engineering, procurement and construction of our growth projects, primarily Crane and Lamesa, equipment to expand our Sandbox operations, and other maintenance and cost improvement capital projects. During the fourth quarter the company generated $43.0 million in cash flow from operations.

Outlook and Guidance

The company anticipates that its capital expenditures for 2019 will be approximately $100 million to $125 million.

We expect to continue with our strategic plan to substantially grow our Industrial segment by focusing on Specialty Minerals and Performance Materials product offerings. We plan to launch and expand the sales of several new offerings this year while growing the underlying base businesses through GDP plus market expansion and continued price increases.

A strong labor market, coupled with real wage growth, bodes well for many of our key industrial markets including: housing, automotive, residential remodeling, biotechnology and food and beverage.

For SandBox, our industry-leading last-mile solution, we are building new equipment as fast as we can to meet unbelievably strong customer demand. Many of our existing and new customers are embarking on substantial, high efficiency well completion programs and believe that SandBox is the only system that gives them the combination of efficiency, flexibility, minimized non-productive time and throughput capacity needed to achieve their objectives.

We are also continuing to innovate and have developed next generation equipment and logistical models which should further enhance efficiency and deliver numerous additional benefits to our customers.

For our Oil & Gas sand business, we expect that annual proppant demand in 2019 will be up 5-10% at around 110 million tons at 50 dollar per barrel oil but could increase to over 130 million tons at 70 dollar per barrel oil. In-basin sand supply will continue to grow, and we would expect that by the end of 2019, we’ll see 67% of the total industry demand supplied by in-basin sand, with 33% supplied by Northern White Sand. We continue to see the Oil & Gas proppant business as attractive and expect to be one of the market leaders. Our recently added local Permian sand mines should operate at capacity while our Northern White mines will continue to be pressured with lower utilization and pricing.

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 as 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, 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 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 as we continue to pursue future plant capacity expansion.
(5)	Reflects contract termination expenses related to strategically exiting a service contract and losses related to sub-leases. 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)	For the fourth quarter and year ended 2018, reflects $164.2 million of goodwill impairments, $97.0 million of long-lived asset impairments and $4.5 million of intangible asset impairments in our Oil & Gas Proppants reporting segment due to a declining shift in demand for Northern White sand caused by some of our customers shifting to local in-basin frac sands with lower logistics costs.
