QUESTIONS & ANSWERS ON VOTING PROCEDURES

Who is entitled to vote at the annual meeting, and how many votes do they have?

Holders of record of our common stock who owned shares as of the close of business on March 7, 2017 (the “Record Date”) may vote at the meeting. Each share is entitled to one vote. There were 81,055,339 shares of common stock outstanding on the Record Date.

When were the enclosed solicitation materials first given to shareholders?

The enclosed Annual Report and proxy card, together with the Notice of Annual Meeting and Proxy Statement, were first made available over the Internet to shareholders on or about March 24, 2017. A Notice of Internet Availability of Proxy Materials, indicating how to access our proxy materials over the Internet, was first sent, or given, to shareholders on or about March 24, 2017.

Why were the proxy materials made available to shareholders over the Internet?

We are taking advantage of a rule adopted by the Securities and Exchange Commission that permits us to furnish proxy materials to shareholders over the Internet. On or about March 24, 2017, we mailed to our shareholders a Notice of Internet Availability of Proxy Materials, which indicates how to access our proxy materials over the Internet. By furnishing this Notice in lieu of mailing our proxy materials, we are lowering the costs and reducing the environmental impact of our annual meeting. You may request to receive a paper copy of the proxy materials by following procedures set forth in the Notice of Internet Availability of Proxy Materials. If a paper copy is requested, shareholders should expect to receive it within several days.

The Notice of Internet Availability of Proxy Materials directs shareholders to the website where you will log in using your unique control number. On this website, you will be able to view our Proxy Statement and Annual Report. You may also cast your vote in a secure manner on the same website.

Who can attend the annual meeting?

All shareholders as of the Record Date may attend the annual meeting in person. Please check the box on your proxy card if you plan to attend the annual meeting in person.

You will need an admission ticket or proof of ownership of our common stock to enter the annual meeting. If you hold shares directly in your name as a shareholder of record, you must present any of the following in order to gain admission to the meeting:

•

the Notice of Internet Availability of Proxy Materials;

•

if you voted using a paper proxy card, the portion of your proxy card to be kept and not submitted with your vote; or

•

if you received an email indicating that the proxy materials are available on the Internet, you may print the email containing your control number.

If your shares are registered or held in the name of your broker, bank or other nominee, your shares are held in “street name.” Please note that if you hold your shares in “street name,” you will need to bring proof of your ownership of our common stock as of the Record Date, such as a copy of a bank or brokerage statement, and check in at the registration desk at the meeting.

Please note that you also may be asked to present valid picture identification, such as a driver’s license or passport.

Because seating is limited, admission to the meeting will be on a first-come, first-served basis. For the safety of attendees, all boxes, handbags and briefcases are subject to inspection. Use of cameras (including cell phones with photographic capabilities), recording devices and other electronic devices is not permitted at the meeting.

What is a quorum of shareholders?

A quorum is the presence at the annual meeting, in person or by proxy, of holders of a majority of the shares of our common stock entitled to vote, including abstentions and broker non-votes (as described below). Because there were 81,055,339 shares of our common stock outstanding on the Record Date, the presence of holders of 40,527,670 shares is a quorum. We must have a quorum to conduct the meeting.

What is a proxy?

A proxy is another person that you authorize to vote on your behalf. We ask shareholders to instruct the proxy how to vote so that all shares of common stock may be voted at the annual meeting even if the holders do not attend the meeting.

What vote is required to approve each proposal?


Proposal	Vote Required	Board’s Recommendation
Election of directors (Proposal No. 1)	Plurality of the votes cast FOR each director nominee	FOR all nominees

Ratification of Grant Thornton as our independent registered public accounting firm for 2017 (Proposal No. 2)	The affirmative vote of a majority of the shares present in person or represented by proxy and entitle to vote at the Annual Meeting	FOR the ratification of Grant Thornton LLP as our independent registered public accounting firm for 2016

Advisory vote to approve executive compensation (say-on-pay) (Proposal No. 3)	The affirmative vote of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting	FOR the compensation of our named executive officers

Amendment of our Second Amended and Restated Certificate of Incorporation to remove the requirement of plurality voting for the election of directors (Proposal No. 4)	The affirmative vote of at least 66 2/3% of all outstanding shares of common stock as of the Record Date	FOR the Amendment of our Second Amended and Restated Certificate of Incorporation to remove the requirement of plurality voting for the election of directors

What are my choices for casting my vote on each matter to be voted on?


Proposal	Voting Options	Effect of Abstentions	Broker Discretionary Voting Allowed?	Effect of Broker Non-Votes
Election of directors (Proposal No. 1)	FOR or WITHHOLD	No effect — not counted as a “vote cast”	No	No effect

Ratification of Grant Thornton as our independent registered public accounting firm for 2017 (Proposal No. 2)	FOR, AGAINST or ABSTAIN	Treated as a vote AGAINST the proposal	Yes	Not applicable

Advisory vote to approve executive compensation (say-on-pay) (Proposal No. 3)	FOR, AGAINST or ABSTAIN	Treated as a vote AGAINST the proposal	No	No effect

Amendment of our Second Amended and Restated Certificate of Incorporation to remove the requirement of plurality voting for the election of directors (Proposal No. 4)	FOR, AGAINST or ABSTAIN	Same effect as a vote AGAINST the proposal	No	Same effect as a vote AGAINST the proposal

Amendment of our Second Amended and Restated Certificate of Incorporation to remove certain provisions relating to ownership of stock by our former controlling shareholder (Proposal No. 5)	FOR, AGAINST or ABSTAIN	Same effect as a vote AGAINST the proposal	No	Same effect as a vote AGAINST the proposal

An abstention occurs when a shareholder affirmatively chooses not to vote on a proposal. A broker non-vote occurs when a broker, bank or other nominee who holds shares for another person has not received voting instructions from the owner of the shares, and under New York Stock Exchange (“NYSE”) rules, does not have discretionary authority to vote on a matter. The matter covered by Proposal No. 2 (ratification of independent registered public accounting firm) is considered a routine matter under the rules of the NYSE for which broker discretionary voting is allowed. Therefore, if you do not vote on this proposal, your broker, bank or other nominee may choose to vote for you or leave your shares unvoted on that proposal. New York Stock Exchange rules, however, do not permit brokerage firms to vote their clients’ unvoted shares in certain other matters, such as the matters set forth in Proposal Nos. 1, 3, 4 and 5. Therefore, if you do not vote on Proposal Nos. 1, 3, 4 or 5, your shares will remain unvoted on those proposals.

If your shares are held by a broker, bank or other nominee, you will receive from that nominee a Notice of Internet Availability of Proxy Materials instructing you how to vote your shares or, if you have elected to receive the proxy materials in paper, a full meeting package, including a voting instruction form to vote your shares. Your broker, bank or other nominee may permit you to provide voting instructions by telephone or by the Internet.

Unless you give other instructions when you vote, the persons named as proxies, Bryan A. Shinn and Christine C. Marshall, will vote in accordance with the Board’s recommendations. We do not expect any other business to properly come before the Annual Meeting; however, if any other business should properly come before the Annual Meeting, the proxy holders will vote as recommended by the Board or, if no recommendation is given, in their own discretion.

How do I vote if I am a shareholder of record?

You must be present in person, or represented by proxy, at the annual meeting to vote your shares. Since many of our shareholders are unable to attend the meeting in person, you may vote your shares in the following ways:


*By Internet*		To access your online proxy card, please visit the website listed on your Notice of Internet Availability of Proxy Materials, or the paper proxy card if you received one, and follow the on-screen instructions. You will need the control number included on your Notice of Internet Availability of Proxy Materials or proxy card. If you vote by Internet, you do not need to mail your proxy card.

*By Telephone*		To vote your shares by telephone, please call the phone number listed on your Notice of Internet Availability of Proxy Materials, or the paper proxy card if you received one, and follow the instructions. You will need the control number included on your Notice of Internet Availability of Proxy Materials or proxy card. If you vote by telephone, you do not need to mail your proxy card.

*By Mail*		If you received a paper proxy card, to vote your shares by mail, please follow the instructions on the proxy card. If you vote your shares by mail, please sign and date your proxy card and mail it in the pre-addressed, postage-paid envelope. If you do not sign your proxy card, your votes cannot be counted.

*In Person*		To ensure your shares are represented, we ask that you vote your proxy by telephone, Internet or mail, even if you plan to attend the meeting. Please check the box on your proxy card if you plan to attend the annual meeting.

If you plan to attend the annual meeting in person and need directions to the meeting site, please contact Investor Relations (phone: 301-682-0304).

Can I vote by proxy even if I plan to attend the annual meeting?

Yes. If you vote by proxy and decide to attend the annual meeting, you do not need to fill out a ballot at the meeting, unless you want to change your vote.

Why might I receive more than one Notice of Internet Availability of Proxy Materials or proxy card? Should I vote on each Notice and proxy card I receive?

First, you may have various accounts with us that are registered differently, perhaps in different names or with different social security or federal tax identification numbers. Second, you may also own shares indirectly through your broker. Your broker will send you a voting instruction form for these shares. You should vote on each Notice, proxy card or voting instruction form you receive in accordance with the instructions set forth in those documents.

Can I receive future proxy materials electronically?

Yes, to receive future proxy materials over the Internet, please visit our transfer agent, Broadridge Corporate Issuer Solutions, Inc., at www.proxyvote.com and follow the instructions to consent to the electronic delivery of materials. If you hold your shares in “street name,” please check the information provided by your broker, bank or other nominee concerning the availability of this service.

How do I change my vote or revoke my proxy?

If you are a shareholder of record, you may change your vote or revoke your proxy at any time before the annual meeting by:

•

notifying Christine C. Marshall, Corporate Secretary, in writing at 8490 Progress Drive, Suite 300, Frederick, MD 21701 that you are changing your vote;

•

providing subsequent Internet or telephone voting instructions;

•

completing and sending in another proxy card with a later date; or

•

attending the annual meeting and voting in person.

If you hold your shares through a broker, bank or other nominee, you should contact your broker, bank or other nominee for instructions on how to change your vote or revoke your proxy.

Who is soliciting my proxy, how is it being solicited, and who pays the cost?

U.S. Silica, on behalf of the Board, through its directors, officers and employees, is soliciting proxies. Proxies may be solicited in person, or by mail, Internet, telephone or facsimile. We pay the cost of soliciting proxies.

Each of the nominated directors has agreed to serve if elected. However, if for some reason one of them is unable to serve or for good cause will not serve, your proxy will vote for the election of another person nominated by the Board, unless the Board reduces the number of directors. Biographical information, including a discussion of specific experience, qualifications, attributes and skills for each of the nominees, and other information about them, is presented beginning on page 6. The Board recommends a vote “FOR” each director nominee.

•

if any of the persons nominated to serve as a director is unable to serve or for good cause will not serve and the Board designates a substitute nominee, or

then shareholders present at the meeting may vote on such items. If you are represented by proxy, your proxy will vote your shares using his or her discretion.

Family Relationships

There are no family relationships between any of our executive officers or directors.

DETERMINATION OF INDEPENDENCE

The Board assesses the independence of its members under the NYSE listing standards. For a director to be considered independent, the Board must affirmatively determine that such director has no material relationship with us. When assessing the materiality of a director’s relationship with us, the Board considers the issue from both the standpoint of the director and from that of persons and organizations with whom or with which the director has an affiliation. The Board reviews the standards adopted by the NYSE to assist it in determining if a director is independent. A director shall be deemed to have a material relationship with us and shall not be deemed to be an independent director if:

•

the director is or has been our employee or an employee of any of our affiliated entities at any time since January 1, 2014, or an immediate family member of the director is or has been an executive officer of us or any of our affiliated entities at any time since January 1, 2014; provided that employment of a director as our interim chairman of the Board or chief executive officer or other executive officer shall not disqualify such director from being considered independent following termination of that employment;

•

the director or an immediate family member is a current partner of a firm that is our internal or external auditor;

•

the director is a current employee of a firm that is our internal or external auditor;

•

the director has an immediate family member who is a current employee of a firm that is our internal or external auditor and personally works on our audit;

•

the director or an immediate family member was at any time since January 1, 2014 (but is no longer) a partner or employee of a firm that is our internal or external auditor and personally worked on our audit within that time;

•

the director or an immediate family member, is, or has been at any time since January 1, 2014, employed as an executive officer of another company where any of our present executive officers at the same time serves or served on that company’s compensation committee;

•

the director is a current executive officer or employee, or an immediate family member is a current executive officer, of another company that has made payments to, or received payments from (other than contributions to tax exempt organizations), us for property or services in an amount which, in any of the other company’s last three fiscal years, exceeds the greater of $1.0 million or 2% of such other company’s consolidated gross revenues; or

•

the director has received, or has an immediate family member who has received, during any twelve-month period since January 1, 2014, more than $120,000 in direct compensation from us, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided that such compensation is not contingent in any way on continued service); provided, however, that (i) compensation received by a director for former service as an interim chairman or chief executive officer or other executive officer need not be considered and (ii) compensation received by an immediate family member for service as our employee (other than an executive officer) need not be considered.

The Board has determined that each of Messrs. Bernard, Kacal, Shaver and Stice, a majority of the members of our current Board, has no material relationship with us and is independent under NYSE listing standards. The Board also determined that Daniel Avramovich, who served as a member of the Board until May 2016, had no material relationships with us during his period of Board service and was independent under NYSE listing standards. With respect to Mr. Shaver, the Board considered de minimis (less than $20,000) product sales by us to Axalta Coating Systems in 2015, which it determined were immaterial and did not impair Mr. Shaver’s independence. There were no such sales in 2016. Mr. Shaver is the Chairman and Chief Executive Officer of Axalta Coating Systems.

There were no transactions, employment or other relationships, voting or other agreements or any other arrangements in the last three years that the Board had to consider with respect to the independence determinations for Messrs. Avramovich, Bernard, Kacal and Stice.

Mr. Shinn, who is our President and Chief Executive Officer, is not independent.

CORPORATE GOVERNANCE

Board Composition

Our Board consists of five members. The affirmative vote of a majority of the number of authorized directors is required to change the size of our Board or to fill any vacancies. The term of office for each director is until his or her successor is elected at our annual meeting or his or her death, resignation or removal, whichever is earliest to occur. Shareholders elect directors each year at our annual meeting.

The Board met thirteen times in 2016. Directors are expected to attend all or substantially all meetings of the Board and meetings of committees on which they serve, and in 2016, each of the directors nominated for reelection attended at least 95% of the Board and committee meetings for the period for which he served.

The Board has adopted a policy that encourages each director to attend the annual meeting of shareholders. All five members of the Board attended the 2016 annual meeting.

Compensation Committee Interlocks and Insider Participation

No interlocking relationships exist between the members of our Compensation Committee and the board of directors or compensation committee of any other company.

Role of Board of Directors in Risk Oversight

The Board, through the Audit Committee, is responsible for risk oversight of our activities. The Audit Committee periodically discusses with management our policies governing the process by which risk assessment and risk management is undertaken and our major risk exposures and the steps management has taken to monitor and control such exposures. In addition, the Compensation Committee reviews the risks arising from our compensation policies and practices to determine whether those risks are reasonably likely to have a material adverse effect on us. The Board believes that our current Board leadership structure, as discussed below, takes into account the Board’s role in risk management oversight including the appropriate delegation of risk management oversight responsibilities to the various committees of the Board.

Leadership Structure of Board of Directors

With respect to the roles of Chairman of the Board and Chief Executive Officer, our Corporate Governance Guidelines provide that the roles may be separated or combined, and the Board exercises its discretion in combining or separating these positions as it deems appropriate in light of prevailing circumstances. The Board believes that the combination or separation of these positions should continue to be considered as part of the succession planning process. Currently the roles are separated, with Mr. Shaver serving as independent Chairman. The Board believes that this structure best serves the interests of shareholders because it allows our Chief Executive Officer to focus primarily on our business strategy and operations and most effectively leverages the experience of the Chairman. It also enhances the Board’s independent oversight of our senior management team and enables better communications and relations between the Board, the Chief Executive Officer and other senior management. In that regard, our independent Chairman presides over the executive sessions of the non-management and independent directors of the Board. Our Corporate Governance Guidelines provide the flexibility for our Board to modify our leadership structure in the future as appropriate. We believe that we, like many U.S. companies, are well served by this flexible leadership structure.

NOMINATIONS FOR DIRECTOR

The Board seeks nominees with a broad diversity of experience, professions, viewpoints, skills and backgrounds that will enable them to make a significant contribution to the Board, our company and our shareholders. The Board believes that the backgrounds and qualifications of the current director nominees, considered as a group, provide a broad diversity of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities. We discuss each nominee’s specific experience, qualifications, attributes and skills in Director Nominees.

The Nominating and Governance Committee annually reviews the qualifications and backgrounds of the directors, as well as the overall composition of the Board, and recommends to the full Board the slate of director candidates to be nominated for election at the next annual meeting of shareholders. This review considers the following criteria, which are set forth in our Corporate Governance Guidelines, a copy of which is maintained on our website, www.ussilica.com:

•

independence;

•

diversity, age, skills and experience;

•

ability to represent all shareholders without a conflict of interest;

•

ability to work in and promote a productive environment;

•

whether the candidate has sufficient time and willingness to fulfill the substantial duties and responsibilities of a director;

•

whether the candidate has demonstrated the high level of character and integrity expected by us;

•

whether the candidate possesses the broad professional and leadership experience and skills necessary to effectively respond to the complex issues encountered by a publicly-traded company; and

•

ability to apply sound and independent business judgment.

As set forth in the charter of the Nominating and Governance Committee, if a shareholder were to recommend a director candidate, the Nominating and Governance Committee would consider such candidate using the same process and criteria used for candidates recommended by management or the Board. From time to time, the Nominating and Governance Committee may retain third-party search firms to assist the Board in identifying and evaluating potential nominees to serve on the Board.

COMMUNICATIONS WITH BOARD OF DIRECTORS

The Board has adopted a policy whereby any communications from our shareholders or other interested parties to the Board shall be directed to our Corporate Secretary, who will forward all such communications to Mr. Shaver as the Board’s designated director. Mr. Shaver will determine whether any of such communications should be forwarded to other members of the Board. Any communication addressed to a particular director, the Chairman of a particular Board committee or the non-employee directors as a group will be forwarded directly to those individuals.

Communications that do not directly relate to the directors’ duties and responsibilities will be excluded from distribution. Such excluded items may include “spam,” advertisements, mass mailings, form letters and email campaigns that involve unduly large numbers of similar communications, solicitations for goods, services, employment or contributions, surveys and individual product inquiries or complaints. Additionally, communications that appear to be unduly hostile, intimidating, threatening, illegal or similarly inappropriate will be screened for omission. Any omitted or deleted communications will be made available to any director upon request.

Any shareholder or other interested party who wishes to communicate with the Board may submit such communication in writing to the Corporate Secretary, U.S. Silica Holdings, Inc., 8490 Progress Drive, Suite 300, Frederick, Maryland 21701.

TRANSACTIONS WITH RELATED PERSONS

Policies for Approval of Related Person Transactions

We have adopted a written policy with respect to related party transactions. Under our related person transaction policy, a “Related Person Transaction” is any transaction, arrangement or relationship between us or any of our subsidiaries and a Related Person not including any transactions involving $120,000 or less when aggregated with all similar transactions. A “Related Person” is any of our executive officers, directors or director nominees, any stockholder beneficially owning in excess of 5% of our stock or securities exchangeable for our stock, any immediate family member of any of the foregoing persons, and any firm, corporation or other entity in which any of the foregoing persons is an executive officer, a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest in such entity.

Pursuant to our Related Person Transaction policy, any Related Person Transaction must be approved or ratified by a majority of the disinterested directors on the Board or a designated committee thereof consisting solely of disinterested directors. In approving any Related Person Transaction, the Board or the committee must determine that the transaction is on terms no less favorable to us in the aggregate than those generally available to an unaffiliated third party under similar circumstances.

Transactions with Related Persons, though not classified as Related Person Transactions by our policy and thus not subject to its review and approval requirements, may still need to be disclosed if required by the applicable securities laws, rules and regulations.

Other than compensation agreements and other arrangements that are described under Executive and Director Compensation, since January 1, 2016, there has not been, and there is not currently proposed, any transaction or series of similar transactions to which we were or will be a party in which the amount involved exceeded or will exceed $120,000 and in which any of our directors, executive officers, holders of more than 5% of any class of our voting securities or any member of the immediate family of the foregoing persons had or will have a direct or indirect material interest.

REPORT OF THE AUDIT COMMITTEE

The role of the Audit Committee is to assist the Board in its oversight of our responsibility relating to: (i) the integrity of our financial statements; (ii) compliance with legal and regulatory requirements; (iii) the independent registered public accounting firm’s qualifications and independence; and (iv) the performance of our internal auditors and independent registered public accounting firm. The Audit Committee operates pursuant to a charter, a current copy of which is available on our website at www.ussilica.com. Management is responsible for the preparation, presentation and integrity of our financial statements, accounting and financial reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for auditing our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (“PCAOB”) and expressing an opinion as to their conformity with accounting principles generally accepted in the United States. The independent registered public accounting firm has free access to the Audit Committee to discuss any matters they deem appropriate.

In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements with management and the independent registered public accounting firm. The Audit Committee also has discussed with management and the independent registered public accounting firm management’s assessment of, and the independent registered public accounting firm’s audit of, the effectiveness of our internal control over financial reporting. The Audit Committee relies without independent verification on the information provided to us and on the representations made by management and the independent registered public accounting firm. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as currently in effect. Finally, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, as currently in effect, and has considered whether the provision of non-audit services by the independent registered public accounting firm is compatible with maintaining the independent registered public accounting firm’s independence and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence.

Based upon the reports and discussions described in this report, the Audit Committee recommended to the Board that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2016 for filing with the SEC.

EXECUTIVE AND DIRECTOR COMPENSATION

Compensation Discussion and Analysis

In this compensation discussion and analysis, we explain our general compensation philosophy for the executives named in the Summary Compensation Table, our named executive officers, as well as provide an overview and analysis of the different material elements of compensation that we provide our named executive officers. We have organized our discussion and analysis as follows:

•

First, we provide a summary of our 2016 performance.

•

Second, we discuss our compensation objectives, philosophy and practices.

•

Third, we discuss our use of compensation consultants and our approach to benchmarking the compensation for each of the named executive officers.

•

Finally, we describe each material element of compensation that we pay to our named executive officers, how we selected the various elements and amounts of compensation, and how decisions we make about one element of compensation fit into our overall compensation program and affect decisions regarding other elements of compensation.

Named Executive Officers

Our named executive officers for 2016 are as follows:


Name		Title
Bryan A. Shinn		President and Chief Executive Officer
Donald A. Merril		Executive Vice President and Chief Financial Officer
Bradford B. Casper		Executive Vice President and Chief Commercial Officer
Michael L. Winkler		Executive Vice President and Chief Operating Officer
John P. Blanchard		Senior Vice President and President, Industrial & Specialty Products

U.S. Silica 2016 Performance

Heading into 2016, we expected the oil and gas markets to be volatile and the downturn in the oil and gas markets that began in 2015 to continue to negatively affect demand for our frac sand products and the financial performance of our Oil & Gas Proppants segment. As a result, the Compensation Committee established an Adjusted EBITDA target tied to the average spot price for West Texas Intermediate (“WTI”) crude oil as well as business and personal objectives focused on conserving cash, gaining market share in our Oil & Gas Proppants segment and improving contribution margin in our Industrial & Specialty Products segment, as discussed in more detail below in Performance-Based Cash Incentives.

As expected, the oil and gas markets continued to be volatile in 2016. In 2016:

•

spot prices for WTI crude oil remained below $45 per barrel and the average WTI spot price in 2016 was over 60% below the peak price in 2014;

•

the number of land rigs operating in oil and gas basins in the United States remained down by over 60% from its peak in 2014;

•

frac sand pricing remained under pressure, particularly during the first nine months of 2016; and

•

the number of drilled but uncompleted wells remained significant, which affected our results because our frac sand products are used in the well completion process.

As a result, as compared to 2015:

•

revenue decreased by 13%; and

•

average selling price per ton of sand sold in our Oil & Gas Proppants segment declined by 20%.

Nonetheless, we were able to accomplish the following during the year:

•

achieved Adjusted EBITDA, as defined in our annual bonus incentive plan, of $24.2 million, which was in excess of our Adjusted EBITDA target under the plan of $20 million based on the average WTI spot price in 2016 of $43.27 per barrel;

•

increased the tons of sand sold by the Oil & Gas Proppants segment by 6% compared to 2015;

•

increased contribution margin in our Industrial & Specialty Products segment by approximately 13% as compared to 2015 through the introduction of new, higher margin products;

•

acquired New Birmingham, Inc. (“NBI”), which owned a regional sand mine and plant located in Tyler, Texas;

•

acquired Sandbox Enterprises, LLC (“Sandbox”), a “last mile” logistics solution for frac sand in the oil and gas industry;

•

completed two common stock issuances resulting in total net proceeds of $653.2 million; and

•

continued to manage cash prudently, resulting in cash on hand of $711.2 million as of December 31, 2016.

In addition, we began to see improvement in the oil and gas markets towards the end of 2016, which had a positive effect on our Oil & Gas Proppants segment. For instance, in the fourth quarter of 2016 as compared to the third quarter of 2016:

•

sales in the segment increased 58%;

•

tons of sand sold in the segment increased 29%; and

•

the average selling price per ton of sand sold in the segment increased 23%.

Adjusted EBITDA and segment contribution margin are non-GAAP measures. We use Adjusted EBITDA and segment contribution margin as metrics in our cash annual bonus incentive plan as below in Performance-Based Cash Incentives. We provide a reconciliation to the most directly comparable GAAP financial measures in How We Evaluate Our Business in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our 2016 Annual Report on Form 10-K.

Despite the continued difficult economic and market conditions that affected financial results for an overwhelming majority of companies in our industry and across the broad sector of companies whose financial results are significantly influenced by the oil and gas markets, our shareholders recognized a positive total shareholder return (“TSR”) in 2016 and were not as negatively affected as were the shareholders of most of our peer companies during the downturn in the oil and gas markets. Specifically, the table below summarizes our TSR over three different time periods—all of which culminate with December 31, 2016—relative to the peer group against which we benchmarked our executive compensation:


Benchmark	1-Year TSR 12/31/2015— 12/31/2016			3-Year TSR 12/31/2013— 12/31/2016			Since U.S. Silica IPO 2/1/2012— 12/31/2016
2016 Proxy Peer Group Median⁽¹⁾		63.9	%		-18.3	%		-13.0	%

U.S. Silica Holdings, Inc.		205.0	%		72.5	%		285.2	%

U.S. Silica Percentile Rank Relative to 2016 Proxy Peer Group Median		83^rd percentile			93^rd percentile			91^st percentile

⁽¹⁾

The companies included in the 2016 proxy peer group are listed below in Benchmarking. The data shown above excludes Rosetta Resources Inc. because it was acquired by Noble Energy, Inc. in July 2015 and C&J Energy Servies, Inc., which completed financial restructuring and emerged from Chapter 11 bankruptcy in January 2017. TSR data for Fairmount Santrol Holdings Inc. is included for only the 1-year TSR period because the company began trading publicly in October 2014. TSR data for Forum Energy Technologies, Inc. is included for only the 1-year and 3-year TSR periods because the company began trading publicly in April 2012.

In light of our overall financial performance in 2016, the Compensation Committee determined to pay the named executive officers a performance-based cash incentive award for 2016 as discussed below in Performance-Based Cash Incentives.

Executive Compensation Objectives and Philosophy

The key objectives of our executive compensation programs are (1) to attract, motivate, reward and retain superior executive officers with the skills necessary to successfully lead and manage our business, (2) to achieve accountability for performance by linking annual cash incentive compensation to the achievement of measurable performance objectives, and (3) to align the interests of the executive officers and our shareholders through short-and long-term incentive compensation programs. For our named executive officers, these short- and long-term incentives are designed to accomplish these objectives by providing a significant financial correlation between our financial results and their total compensation.

At our 2016 annual meeting, we received significant support from our shareholders for our 2015 executive compensation program with approximately 80% of the votes cast in favor of the say-on-pay proposal. We believe the voting results demonstrated strong support for the overall design and results of our compensation program in 2015, which included strong alignment between pay and performance. For 2016, the overall design of our executive compensation program remained largely unchanged with the exception of removing stock options from the mix of equity awards granted as part of the long-term incentive program to better align with market practices and changing the performance measure for the long-term performance share units from cumulative Adjusted EBITDA to relative TSR as compared to a peer group to diversify the performance metrics used in the executive compensation program, as discussed in Material Elements of Compensation – Long-Term Incentive Program.

In 2016, as reflected in the charts on the next page, a significant portion of the compensation of our Chief Executive Officer and other named executive officers consisted of equity incentive compensation contingent upon the achievement of financial performance, business unit and/or individual performance goals. Performance-based compensation aligns the interests of our Chief Executive Officer and other named executive officers with the interests of our shareholders because the amount of compensation ultimately received will vary with our company’s financial performance. Additionally, equity compensation derives its value from our equity value, which is likely to fluctuate based on our financial performance.

We seek to apply a consistent philosophy to compensation for all executive officers. Our compensation philosophy is based on the following core principles:

To Pay for Performance

Individuals in leadership roles are compensated based on a combination of total company, business unit and individual performance factors. Total company performance is evaluated in part based on the degree to which pre-established financial objectives are met. Business unit and individual performance are evaluated based upon several individualized objectives. The Chief Executive Officer assessment process is managed by the Chairman of the Compensation Committee with input from all Board members. The Chairman solicits input from other Board members on the Chief Executive Officer’s performance relative to the pre-established key objectives for the year. Each Board member is invited to provide feedback on the Chief Executive Officer’s performance. The Chairman gathers this feedback and synthesizes it into a clear, balanced view of actual results as compared to the objectives. With guidance from the compensation consultant, the Chairman provides a pay recommendation to the Compensation Committee consistent with the feedback he has received from the Board.

The other management team members, including our named executive officers, provide objectives to the Board at the beginning of the year. The Chief Executive Officer assesses each management team member against those objectives and reports back to the Compensation Committee at the beginning of the following year. With guidance from the compensation consultant, the Chief Executive Officer provides pay recommendations for the management team members to the Compensation Committee consistent with his assessment of the executives’ performance.

The objectives and results for 2016 for our named executive officers are discussed in more detail below in Material Elements of Compensation.

To Pay Competitively

We are committed to providing a total compensation program designed to retain our high-caliber performers and attract superior leaders to our company. To achieve this goal, we compare our pay practices and overall pay levels with oil and gas, mining and logistics organizations as discussed below in Use of Compensation Consultants and Benchmarking.

To Pay Equitably

We believe that it is important to apply generally consistent guidelines for all executive officer compensation programs. In order to deliver equitable pay levels, the Compensation Committee considers depth and scope of accountability, complexity of responsibility, qualifications and executive performance, both individually and collectively as a team.

Executive Compensation Practices

In addition to establishing a pay-for-performance culture, we have instituted the following executive compensation practices:

What We Do

☑

Clawback Policy. The Compensation Committee has adopted a clawback policy that applies to all executive officers with respect to short-term and long-term performance-based incentive compensation as more fully described in Clawback Policy below.

☑

Stock Ownership Guidelines. Stock ownership requirements for our executive officers create alignment with shareholder interests and require a significant ownership level as described in Stock Ownership Requirements below.

☑

Limited Perquisites. Perquisites provided to executives are limited and reviewed annually by the Compensation Committee.

☑

Independent Compensation Consultant. The Compensation Committee retains its own independent compensation consultant.

What We Don’t Do

☒

No Guaranteed Bonuses. We do not provide guaranteed bonuses to any of our executive officers.

☒

No Pension Plan. We do not provide any qualified or non-qualified pension plans or other post-employment defined benefit plans to our executive officers.

☒

No Special Tax Gross-ups. We do not provide tax gross-ups on perquisites received by our executive officers, except for tax gross-up on relocation benefits, which is provided to all employees.

☒

No Hedging; Limited Pledging. Our insider trading policy prohibits all employees, including the named executive officers, from using our stock in any hedging activities. Employees may not pledge our stock as collateral or hold it in a margin account without obtaining approval from the General Counsel or Chief Compliance Officer.

☒

No Option Repricing, Reloads or Buyouts. Our Amended and Restated 2011 Incentive Compensation Plan does not allow the repricing or cash buyout of stock options or stock appreciation rights, reload provisions in stock option grants or the payment of dividends on unvested performance shares and requires all awards to have at least a one-year vesting period.

Use of Compensation Consultants and Benchmarking

Overview

We administer compensation changes for all employees, including our named executive officers, on an annual basis. Each February, after performance results for the prior year are finalized, incentive payouts for the prior performance period are determined and performance metrics for the current year’s annual and long-term incentive grants are approved by the Compensation Committee. This administration schedule permits compensation decisions to be made within a reasonable time after finalizing our financial and operational results, so that an assessment of business and individual contributions to corporate performance can provide alignment of pay with performance. This schedule also facilitates the establishment of performance metrics that are consistent with our business plan objectives communicated to shareholders at the beginning of the year.

Use of Compensation Consultants

Our Compensation Committee retains a compensation consultant to assist the Committee in determining both the mix of compensation that we make available to our named executive officers and the amount of each element, taking into account the general goals of our compensation program. The compensation consultant also provides research and market data to the Compensation Committee and generally advises the Committee on matters relating to its executive compensation decision making. A representative of the compensation consultant generally attends meetings of the Compensation Committee at which executive compensation matters are discussed and also communicates directly with the Compensation Committee Chair.

Since 2013, the Compensation Committee has retained Exequity LLP (“Exequity”) as the executive compensation consultant to the Compensation Committee. The Compensation Committee has determined that the work of Exequity did not raise any conflicts of interest in 2016. In making this assessment, the Compensation Committee considered the independence factors enumerated in Rule 10C-1(b) under the Exchange Act, including the fact that Exequity does not provide any other services to us, the level of fees received from us as a percentage of Exequity’s total revenue, policies and procedures employed by Exequity to prevent conflicts of interest, and whether the individual Exequity advisers to the Compensation Committee own any of our stock or have any business or personal relationships with members of the Compensation Committee or our executive officers.

Benchmarking

It is the Compensation Committee’s intent to provide target total compensation opportunities for our executives that are generally comparable to median target total compensation opportunities among relevant peer executives—and are calibrated such that actual total compensation realized would (a) exceed peer median pay opportunities in the event that company and individual performance is strong, and (b) be below median pay opportunities in the event that company and individual performance is not strong.

Proxy Peer Group

With assistance from Exequity, in August 2015, our Compensation Committee established the following peer group for 2016 (the “2016 proxy peer group”) to benchmark the components of the total direct compensation of our named executive officers:


C&J Energy Services, Inc.	Fairmount Santrol Holdings Inc.*	Oasis Petroleum Inc.
CARBO Ceramics Inc.	Forum Energy Technologies, Inc.*	Oil States International, Inc.*
Clayton Williams Energy, Inc.	Headwaters Inc.*	PDC Energy Inc.
Dril-Quip Inc.	Intrepid Potash, Inc.	Pioneer Energy Services Corp.
Eagle Materials, Inc.	Minerals Technologies Inc.	Rosetta Resources Inc.

*	New to peer group for 2016

Three companies were removed from the 2015 proxy peer group because the Compensation Committee deemed them to be too small in terms of market capitalization as compared to us (which had a market capitalization of approximately $1.5 billion as of the time Exequity’s report was generated in July 2015). The companies that were removed from the peer group and their respective market capitalizations at the time Exequity’s report was generated in July 2015 were: Comstock Resources Inc. ($188 million), Energy XXI Limited ($296 million) and Gulfmark Offshore Inc. ($316 million). The companies that replaced the three companies removed from the 2015 proxy peer group to form the 2016 proxy peer group had approximate market capitalizations as of July 2015 as follows:

•

Fairmount Santrol Holdings Inc. ($1.4 billion)

•

Forum Energy Technologies, Inc. ($1.9 billion)

•

Headwaters Inc. ($1.4 billion)

•

Oil States International, Inc. ($2.0 billion)

As of October 2015, when Exequity completed its study of target total direct compensation levels for the 2016 proxy peer group, the median market capitalization and most recently reported annual revenues for the 2016 proxy peer group were approximately $1.3 billion and $1.1 billion, respectively. Meanwhile, our market capitalization and most recently reported fiscal year revenues at the time the study was completed were $882 million (40^th percentile relative to the 2016 proxy peer group) and $877 million (31^st percentile relative to the 2016 proxy peer group), respectively.

Survey Peer Group

As in prior years, in 2016, the Compensation Committee reviewed a group of companies in the energy, mining and logistics industries that participated in Equilar’s survey of compensation for key executive positions (the “2016 survey peer group”) to provide additional context for 2016 executive compensation-related discussions.

Specialty Chemicals Peer Group

For 2016, with assistance from Exequity, the Compensation Committee also reviewed executive compensation for the group of specialty chemicals companies listed below to supplement the 2016 proxy peer group benchmarking (the “2016 specialty chemicals peer group”). The Committee deemed specialty chemicals companies to be potential secondary sources of and destinations for our executive talent in addition to the proxy peer group companies, particularly since our Chief Executive Officer and other executive officers had previously been employed in the chemicals industry. As a result, the Compensation Committee wanted to determine whether the compensation of our executive officers was competitive with the executive compensation paid by the companies in the 2016 specialty chemicals peer group.


A. Schulman, Inc.	Koppers Holdings Inc.	Sensient Technologies Corporation
Albemarle Corporation	Kraton Performance Polymers Inc.	Sigma-Aldrich Corporation
Chemtura Corporation	NewMarket Corporation	Stepan Company
Cytec Industries Inc.	Olin Corp.	Tronox Limited
Ferro Corporation	OM Group	Valhi, Inc.
HB Fuller Co.	The Scotts Miracle-Gro Company	Westlake Chemical Corp.

As of January 2016, when Exequity reviewed the target total direct compensation levels for the 2016 specialty chemicals peer group, the median market capitalization and most recently reported annual revenues for the 2016 specialty chemicals peer group were approximately $1.9 billion and $2.1 billion, respectively. Meanwhile, our market capitalization and most recently reported fiscal year revenues at the time the study was completed were $1.1 billion (40^th percentile relative to the 2016 specialty chemicals peer group) and $877 million (below all members of the 2016 specialty chemicals peer group), respectively.

Analysis of Benchmarking Data

Exequity provided market compensation data using the above-referenced peer groups established by the Compensation Committee. Exequity then analyzed the benchmark data and provided advice and insight to the Compensation Committee regarding competitive pay levels for the named executive officers. At the end of 2015 and the beginning of 2016, the Compensation Committee reviewed the benchmark data from the 2016 proxy peer group and 2016 survey peer group for the Chief Executive Officer, and the Compensation Committee and the Chief Executive Officer reviewed the benchmark data from those peer groups for the other named executive officers, at the 25^th, 50^th and 75^th percentiles as a reference for determining the 2016 base salary, 2016 cash incentive target awards and 2016 long-term incentive target awards for our named executive officers.

While the Compensation Committee reviewed the benchmark data from the 2016 specialty chemicals peer group, it ultimately did not rely on that data in determining 2016 executive compensation.

Material Elements of Compensation

The elements of our compensation program in 2016 were:

•

base salary;

•

performance-based cash incentives;

•

equity-based incentives; and

•

certain additional executive benefits and perquisites.

The Compensation Committee will seek to consider each of these elements of compensation at the same time to enable the Compensation Committee to consider their impact on total compensation and the extent to which the determinations made will reflect the principles of our compensation philosophy and related guidelines with respect to allocation of compensation among certain of these elements and total compensation. We strive to achieve an appropriate mix between the various elements of our compensation program to meet our compensation objectives and philosophy; however, we do not apply any rigid allocation formula in setting our executive compensation, and we may make adjustments to this approach for various positions after giving due consideration to prevailing circumstances.

Base Salary

We provide a base salary to our executive officers to compensate them for their services during the year and to provide them with a stable source of income. The base salaries for our named executive officers are established based in large part on the salaries established for persons holding similar positions with the proxy peer group and by the Committee’s review of other factors, including:

•

the individual’s performance, results, qualifications and tenure;

•

the job’s responsibilities, pay mix (base salary, annual cash incentives and other executive benefits) and similar companies’ compensation practices; and

•

our ability to replace the individual.

Our named executive officers did not receive a base salary increase in 2016 due to the continued downturn in the oil and gas markets.

In the future, we expect that salaries for executive officers will continue to be reviewed and benchmarked against the relevant peer group annually, as well as at the time of a promotion or other change in level of responsibilities, or when competitive circumstances or business needs may require.

Performance-Based Cash Incentives: Annual Bonus Incentive Plan (“ABIP”)

2016 ABIP Design

We pay performance-based cash incentives under the ABIP in order to align the compensation of our employees, including our named executive officers, with our short-term operational and performance goals and to provide near-term rewards for employees to meet these goals. For 2016, these incentive payments were based on the attainment of pre-established objective financial goals, business unit performance objectives and individual personal performance objectives. Our short-term, performance-based cash incentive awards made to our named executive officers are intended to qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code, as amended (the “Code”). The following table shows each named executive officer’s performance-based cash incentive minimum, threshold, target and maximum payouts under the ABIP as of December 31, 2016, which were established by the Compensation Committee in February 2016.


Name	Minimum Payout ($)		Threshold Payout ($)		Target Payout ($)		Maximum Payout ($)
Bryan A. Shinn		0		325,000		650,000		1,300,000
Donald A. Merril		0		135,575		271,150		542,300
Bradford B. Casper		0		125,000		250,000		500,000
Michael L. Winkler		0		202,500		405,000		810,000
John P. Blanchard		0		108,850		217,700		435,400

In order for the 2016 ABIP awards for employees who are covered under Code Section 162(m), which includes most of the named executive officers, to qualify as performance-based compensation, the Compensation Committee determined in February 2016 that the 2016 ABIP awards for covered employees would fund at each individual’s maximum (200% of target, as shown above) award opportunity if we achieved sales, as audited and determined in accordance with U.S. generally accepted accounting principles (“sales”), for the year ended December 31, 2016 of at least $200 million.

Within this framework, the Compensation Committee had authority to use negative discretion to adjust downward the payout achieved under the financial performance goal by each named executive officer based on company and individual performance components. Each of the performance components is independent of the other performance components and is eligible for payout even if the other performance components are not achieved; provided that in no event would any payment pursuant to the 2016 ABIP exceed 200% of the executive officer’s overall 2016 ABIP target.

The named executive officers’ performance components under the 2016 ABIP were weighted as follows:


Name	Company Performance Component (%)		Personal Performance Component (%)		ISP Segment Component (%)
Bryan A. Shinn		80		20		—
Donald A. Merril		80		20		—
Bradford B. Casper		80		20		—
Michael L. Winkler		80		20		—
John P. Blanchard		20		20		60

•

“Company Performance Component”: If the average West Texas Intermediate (“WTI”) closing spot price (the “average WTI price”) from January 1 through December 31, 2016 was

•

less than $45.00 per barrel, then the 2016 Adjusted EBITDA target would be $20 million;

•

greater than $60.00 per barrel, then the 2016 Adjusted EBITDA target would be $90 million; and

•

between $45.00 and $60.00 per barrel, then the 2016 Adjusted EBITDA target would be determined using linear interpolation between $20 million and $90 million. For example, if the average WTI price was $52.50 per barrel, the 2016 Adjusted EBITDA target would equal $55 million.

LOGO

The Compensation Committee determined that an Adjusted EBITDA target tied to the average WTI price appropriately addressed the uncertainty and volatility in oil and gas markets heading into 2016.

The Company Performance Component funded the 2016 ABIP as follows:


2016 Results (Adjusted EBITDA)	Percentage of Target Paid
Less than 80% of Adjusted EBITDA target		0	%
80% of Adjusted EBITDA target		50	%	Minimum threshold for any payout
100% of Adjusted EBITDA target		100	%	Target
110% of Adjusted EBITDA target		150	%
120% of Adjusted EBITDA target		200	%	Maximum

“Adjusted EBITDA” was defined as our consolidated earnings before interest, taxes, depreciation and amortization, as audited, as adjusted by the Compensation Committee to take into consideration the following: (i) restructurings, discontinued operations, extraordinary items or events (including acquisitions and divestitures), and other unusual or non-recurring charges (including expenses incurred with acquisitions and divestitures), (ii) an event either not directly related to our operations or not within the reasonable control of our management, (iii) losses incurred as a result of any goodwill impairment, or (iv) a change in tax law or accounting standards required by U.S. generally accepted accounting principles. Adjusted EBITDA was used because it is a key metric used by management and the Board to assess our operating performance. Adjusted EBITDA is a non-GAAP measure. We provide a reconciliation of Adjusted EBITDA to the most directly comparable GAAP financial measure in How We Evaluate Our Business in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our 2016 Annual Report on Form 10-K.

•

“Personal Performance Component”: The named executive officer’s personal performance capped at 200% of the personal performance target weighting, including the following operational and performance objectives:

•

continued cash management and cost reduction in an uncertain market environment;

•

improving the accounting and financial structure while ensuring continued effective internal control over financial reporting;

•

meeting environmental, health and safety performance goals;

•

delivering budgeted savings under our cost improvement program

•

developing a flexible capital expenditure budget to meet changing and volatile market conditions;

•

leading acquisition and existing business growth initiatives;

•

improving the Oil & Gas Proppants segment market share;

•

developing a growth strategy for the Industrial & Specialty Products segment;

•

expanding product offerings to further differentiate our business model; and

•

continued enhancement of relationships with key customers.

•

“ISP Segment Component”: For Mr. Blanchard only, achieving contribution margin in the Industrial & Specialty Products segment of at least $71 million in 2016.

Determination of 2016 ABIP Payouts

At the Compensation Committee meeting in February 2017, the determination of the 2016 ABIP payouts to the named executive officers took into account the following material factors:

•

Sales, as audited and determined in accordance with U.S. generally accepted accounting principles, for the year ended December 31, 2016 was $559.6 million, greater than the $200 million of sales needed to trigger a payout under the 2016 ABIP.

•

The average WTI price from January 1 through December 31, 2016 was $43.27 per barrel, which set the 2016 Adjusted EBITDA target at $20 million.

•

Adjusted EBITDA for the year ended December 31, 2016, as defined in the 2016 ABIP, as compared to threshold, target and maximum performance under the 2016 ABIP:


Adjusted EBITDA (in millions)
Threshold (80% of target)		Target		Maximum (120% of target)		Actual		Payout Achieved
$	16	$	20	$	24	$	24.2		200	%

For a calculation of 2016 Adjusted EBITDA, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—How We Evaluate Our Business in our Annual Report on Form 10-K for the year ended December 31, 2016.

•

The Chief Executive Officer presented to the Compensation Committee his proposed 2016 ABIP payouts for the other named executive officers.

•

The Compensation Committee reviewed the benchmarking data discussed above in Benchmarking.

•

The Compensation Committee considered and agreed with the individual performance assessments that the Chief Executive Officer presented to the Compensation Committee for each other named executive officer as well as the Chief Executive Officer’s self-assessment. The Compensation Committee members also discussed their own assessment of each named executive officer’s performance, including the Chief Executive Officer assessment, which was managed by the Chairman of the Compensation Committee.

•

The Compensation Committee discussed the relative compensation and organizational roles and responsibilities of the named executive officers.

•

The Compensation Committee considered the following corporate, business unit and personal performance achievements:

•

improved our cash position, including by raising over $650 million in two equity issuances, and ended 2016 with over $700 million of cash on hand;

•

completed the acquisition of NBI, which owned a facility and mine in Tyler, Texas, which is being successfully integrated into our systems and processes;

•

completed the acquisition of Sandbox, a “last mile” logistics solution for frac sand in the oil and gas industry;

•

grew volumes in the Oil & Gas Proppants segment by 6%;

•

realized 2016 contribution margin for the Industrial & Specialty Products segment of $79 million;

•

executed on the budgeted capital expenditure plan and cost reduction projects;

•

realized savings across the supply chain;

•

developed an acquisition pipeline for the Industrial & Specialty Products business to enable the continuous evaluation of strategic transactions;

•

continued to develop relationships with senior executives at key customers;

•

ensured a successful audit of our financial statements and internal control over financial reporting in which no material weaknesses were identified;

•

streamlined accounting and financial reporting structures and created business segment chief financial officer positions; and

•

implemented improved safety standards and tracking at each facility.

The Compensation Committee determined that the 2016 ABIP payouts it approved for the named executive officers were reasonable after reviewing the foregoing material factors.

Based on the foregoing factors, the Compensation Committee determined that the following payouts should be made to the named executive officers under the 2016 ABIP:


Name	Payout ($)		Payout as % of Target Award
Bryan A. Shinn		1,300,000		200
Donald A. Merril		542,300		200
Bradford B. Casper		500,000		200
Michael L. Winkler		810,000		200
John P. Blanchard		378,000		174

Long-Term Incentive Program

At the end of 2015 and in the first quarter of 2016, the Compensation Committee reviewed with Exequity the long-term incentive program for certain of our employees, including the named executive officers, that had been developed in 2015 and decided to remove stock options from the mix of equity awards made under the program to better align with market practices and to change the performance measure for the performance share units from cumulative Adjusted EBITDA over three years to relative total shareholder return over three years to diversify the performance metrics used in the overall executive compensation program.

Under the 2016 long-term incentive program, each of our named executive officers has been provided equity grants consisting of the following performance-based component and retention-oriented, time-vested component:

•

55% of the total grant value in the form of performance share units; and

•

45% of the total grant value in the form of restricted stock units.

We believe our long-term incentive program aligns the interests of our named executive officers with our shareholders, provides our named executive officers with incentives linked to long-term performance and creates an ownership culture. In addition, the vesting feature of our long-term incentive program contributes to executive retention because this feature provides an incentive to our named executive officers to remain in our employ during the vesting period.

In determining the mix of equity awards and the individual target award opportunities under the long-term incentive program, the Board and the Compensation Committee exercised its judgment and discretion, in consultation with our Chief Executive Officer and the Committee’s compensation consultant, and considered, among other things, the role and responsibility of the named executive officer, competitive factors including a review of market data as discussed in Benchmarking, the amount of stock-based equity compensation already held by the named executive officer, and the cash-based compensation received by the named executive officer to determine the long-term incentive program opportunity that was approved.

2016-2018 Performance Share Units

The ultimate number of performance share units to be earned by the named executive officers will be based on our TSR over the period from January 1, 2016 through December 31, 2018 expressed as a percentage ranking as compared to the TSR for the performance period of each of the companies in the S&P SmallCap 600 Energy Sector Index that are part of such index at both the beginning and the end of the performance period, in accordance with the following schedule:


TSR Ranking January 1, 2016 through December 31, 2018		Number of PSUs Vested as Percentage of Target
Below 30th percentile		0%
30th percentile		50% (Threshold)
50th percentile		100%
75th percentile		150%
At or Above 90th percentile		200% (Maximum)

No performance share units will be earned if the threshold goal is not met. To the extent that the actual TSR ranking for the performance period is between goals, the number of performance share units to become vested will be determined on a pro rata basis using straight line interpolation.

For purposes of the performance share units, the term “TSR” shall mean total shareholder return for a company, expressed as a percentage, determined by dividing (i) an amount equal to the sum of (x) the difference between the Beginning Stock Price and the Ending Stock Price and (y) the sum of all dividends paid on one share of such company’s stock during the performance period, provided that dividends shall be treated as reinvested on the ex-dividend date at the closing price on that date by (ii) the Beginning Stock Price, as calculated in good faith by the Committee. “Beginning Stock Price” for a company shall mean the average closing price on the applicable stock exchange of one share of the company’s stock for the sixty (60) days immediately prior to the first day of the performance period. “Ending Stock Price” for a company shall mean the average closing price on the applicable stock exchange of one share of the company’s stock for the sixty (60) days immediately prior to the last day of the performance period.

The performance share unit awards approved by the Board and the Compensation Committee in 2016 for each named executive officer are reflected in the Grants of Plan-Based Awards Table below.

2016 Restricted Stock Units

The restricted stock unit awards vest ratably over three years. The restricted stock unit award grants approved by the Board and the Compensation Committee in 2016 for each named executive officer are reflected in the Grants of Plan-Based Awards Table below.

2014-2016 Performance Share Units

Performance share units were granted to each of the named executive officers with a performance period that began on January 1, 2014 and ended December 31, 2016. These grants are included in the Outstanding Equity Awards at Fiscal Year-End table. Based on our cumulative Adjusted EBITDA performance over the performance period, the Compensation Committee determined that no awards were payable under these grants.

Additional Executive Benefits and Perquisites

We provide our executive officers with executive benefits and perquisites that the Board believes are reasonable and in the best interests of our company and our shareholders. Consistent with our compensation philosophy, we intend to continue to maintain our current benefits for our executive officers, including retirement plans, health and welfare benefits and life insurance and long-term disability insurance described below. The Compensation Committee, in its discretion, may revise, amend or add to an officer’s executive benefits if it deems it advisable. We believe these benefits are generally equivalent to benefits provided by comparable companies. We have no current plans to change the levels of benefits provided thereunder.

Retirement Plan Benefits. We sponsor a 401(k) plan covering substantially all eligible employees. Employee contributions to the 401(k) plan are voluntary. We contribute an amount equal to 25% of a covered employee’s eligible contribution up to 8% of a participant’s salary. We also may contribute from 0% to 25% of a covered employee’s eligible contribution up to 8% of a participant’s salary, if applicable, based on our profits from the previous fiscal year as an incentive to encourage our employees to participate in the 401(k) plan. The contributions based on our profits are paid during the Spring of the following fiscal year. In the case of both the matching program and the profit sharing program, an employee is fully vested in our contributions after five years of service. Finally, we also provide a 4% defined contribution of monthly basic income into a participant’s 401(k) account if that participant does not participate in our defined pension plan. An employee is fully vested in these contributions after one year of service. Contributions by participants are limited to their annual tax deferred contribution limit as allowed by the Internal Revenue Service.

None of our named executive officers participate in or have account balances in any qualified or nonqualified defined benefit plans sponsored by us. Either our Board or our Compensation Committee may elect to adopt qualified or nonqualified benefit plans in the future if it determines that doing so is in our best interest.

Health and Welfare Benefits. We offer health, dental and vision coverage for all employees, including our named executive officers, and pay a portion of the premiums for our named executive officers on the same basis as for our other salaried employees.

Life Insurance and Long-Term Disability Insurance. As of December 31, 2016, we offer life insurance up to five times each employee’s annual salary up to a maximum of $600,000. We offer long-term disability insurance equal to 66.67% of an employee’s annual salary, up to a maximum of $10,000 per month. We pay life insurance premiums on behalf of our named executive officers and all other salaried employees equal to one times annual salary. Additional amounts up to the maximum amount are paid by the employee. We pay the premium for long term disability for 60% of salary (up to the $10,000 per month maximum) for all employees, including our named executive officers. The premium for the additional 6.67% is paid for by the employee.

Deferred Compensation. None of our named executive officers participate in or have account balances in our unfunded, deferred compensation plan.

Perquisites. Executive perquisites are discussed in the footnotes to the Summary Compensation Table. We believe that the executive perquisites we provide are de minimis in amount and consistent in form to those offered to executives of our peers listed in Benchmarking. We do not provide tax gross-up on perquisites that are provided to our executive officers, other than tax gross-ups on relocation benefits. We provide tax gross-up to all employees who receive relocation benefits, which is a prevalent market practice.

Employment and Other Agreements

Bryan A. Shinn

In March 2012, we entered into an employment agreement with Mr. Shinn, our President and Chief Executive Officer. Pursuant to the terms of the employment agreement, Mr. Shinn was entitled to an annual base salary of $400,000, which has been adjusted by the Board to $650,000. Mr. Shinn is also eligible to earn a short-term, performance-based cash incentive payment for each year under the annual bonus incentive program in which our other executive officers participate. His target annual incentive has been established by the Board at 100% of his annual base salary.

Mr. Shinn is also entitled to receive benefits in accordance with the health and welfare plans we provide to other members of our senior management. He is also entitled to up to 25 days of paid time off and reimbursement for all reasonable business expenses that he incurs in the course of performing his duties and responsibilities, which are consistent with our policies in effect from time to time with respect to travel, entertainment and other business expenses, subject to our requirements with respect to reporting and documentation of such expenses.

Mr. Shinn’s employment continues until the earlier of his resignation (with or without good reason), death or disability or termination by us (with or without cause). If we terminate Mr. Shinn’s employment without cause or Mr. Shinn resigns for good reason and such termination or resignation is not in connection with a change in control, Mr. Shinn is entitled to receive severance equal to his annual base salary payable in regular installments from the date of termination through the twelve-month anniversary of the date of termination if Mr. Shinn has executed and delivered a general release of any and all claims arising out of or related to his employment with us and the termination of his employment. Mr. Shinn is also entitled to receive reimbursement of the then-prevailing monthly premium for COBRA healthcare coverage if he so elects.

Mr. Shinn has also agreed to customary restrictions with respect to the use of our confidential information and has agreed that all intellectual property developed or conceived by him while he is employed by us which relates to our business is our property. During the term of Mr. Shinn’s employment with us and during the twelve-month period immediately thereafter, Mr. Shinn has agreed not to (i) participate (whether as an officer, director, employee or otherwise) in any businesses that compete with us, (ii) solicit or hire any of our employees and (iii) induce or attempt to induce any customer, supplier, licensee, licensor, franchisee, distributor or other business relation of ours to cease doing business with us or in any way interfere with our relationship with such person or entity. During any period in which Mr. Shinn has breached the above restrictions, we have no obligation to pay Mr. Shinn any severance described above.

In February 2016, in connection with approving a Change in Control Severance Plan for U.S. Silica, as discussed below, the Compensation Committee approved an amendment to Mr. Shinn’s employment agreement to provide for the following severance benefits in the event of his involuntary termination of employment without cause or resignation for good reason, in either case within 24 months immediately following a change in control of U.S. Silica:

•

a lump sum payment equal to two (2) times the sum of (i) Mr. Shinn’s base salary as of the termination date (or, if greater, salary in effect on the first occurrence of the change in control) and (ii) Mr. Shinn’s target annual cash bonus for the year in which the termination occurs (or, if greater, in effect as of the occurrence of the change in control);

•

a prorated annual bonus that Mr. Shinn would have earned for the entire fiscal year in which the termination of employment occurs at target level based on the number of days Mr. Shinn was employed during the year; and

•

continuation of group health insurance coverage for Mr. Shinn and Mr. Shinn’s eligible dependents pursuant to COBRA during the 18 month period following Mr. Shinn’s termination of employment.

Receipt of the foregoing severance benefits is conditioned upon Mr. Shinn executing a general release of claims in our favor and continued compliance with the non-compete and non-solicitation provisions contained in his employment agreement.

Also in February 2016, the Compensation Committee approved an amendment to Mr. Shinn’s existing equity award agreements to align the treatment of the equity awards in the event of Mr. Shinn’s separation from service as a result of a resignation for good reason following a change in control of U.S. Silica with the existing treatment of those equity awards in the event of Mr. Shinn’s separation from service as a result of an involuntary termination of employment without cause following a change in control. Pursuant to the amendment, all stock options and restricted stock units held by Mr. Shinn will vest in full and all performance share units held by him will vest based on target level of performance in the event of his separation from service as a result of a resignation for good reason following a change in control of U.S. Silica. Vested stock options will remain exercisable for a period of three years following Mr. Shinn’s termination. In November 2016, the Compensation Committee approved an amendment to Mr. Shinn’s existing equity award agreements to permit him to elect to reduce the number of shares deliverable to him upon the vesting of an equity award or the exercise of a stock option in an amount up to his maximum individual tax rate, provided that such additional reduction would not result in adverse financial accounting or tax withholding treatment to U.S. Silica.

Mr. Shinn’s severance benefits and the treatment of Mr. Shinn’s equity awards in the event of his termination or a change in control are discussed in more detail below in Potential Payments Upon Employment Termination or Change in Control.

Other Named Executive Officers

None of our other named executive officers have an employment agreement.

In February 2016, the Compensation Committee approved a Change in Control Severance Plan (the “CIC Plan”), as part of its ongoing review of our executive compensation program. Each of our named executive officers is eligible to participate in the CIC Plan.

The CIC Plan provides certain benefits if the named executive officer experiences a separation from service as a result of an involuntary termination of employment without cause or resignation for good reason, in either case within 24 months immediately following a change in control of U.S. Silica. If such events occur and the named executive officer has signed a general release of claims in our favor, the CIC Plan provides the following benefits to such Participant:

•

a lump sum payment equal to 1.5 times the sum of (i) the named executive officer’s base salary as of the termination date (or, if greater, salary in effect on the first occurrence of the change in control) and (ii) the named executive officer’s target annual cash bonus for the year in which the termination occurs (or, if greater, in effect as of the occurrence of the change in control);

•

a prorated annual bonus that the named executive officer would have earned for the entire fiscal year in which the termination of employment occurs at target level based on the number of days the named executive officer was employed during the year; and

•

continuation of group health insurance coverage for the named executive officer and the named executive officer’s eligible dependents pursuant to COBRA during the 18 month period following the named executive officer’s termination of employment.

If a named executive officer has a separate agreement with us that provides for specific severance and benefits in connection with a termination of employment following a change in control, such as Mr. Shinn, the payments and benefits provided by the CIC Plan will be reduced by the payments and benefits under the individual severance agreement.

If the severance payments under the CIC Plan would trigger an excise tax under Sections 280G and 4999 of the Internal Revenue Code, the severance payments would be reduced to a level at which the excise tax is not triggered, unless the named executive officer would receive a greater amount without such reduction after taking into account the excise tax and other federal and state taxes.

Also in February 2016, the Compensation Committee approved an amendment to the existing equity award agreements of each named executive officer to align the treatment of the equity awards in the event of such named executive officer’s separation from service as a result of a resignation for good reason following a change in control of U.S. Silica with the existing treatment of those equity awards in the event of such named executive officer’s separation from service as a result of an involuntary termination of employment without cause following a change in control. Pursuant to the amendment, all stock options and restricted stock units held by the named executive officers will vest in full and all performance share units held by them will vest based on target level of performance in the event of his separation from service as a result of a resignation for good reason following a change in control of U.S. Silica. Vested stock options will remain exercisable for a period of three years following the named executive officer’s termination. In November 2016, the Compensation Committee approved an amendment to each named executive officer’s existing equity award agreements to permit him to elect to reduce the number of shares deliverable to him upon the vesting of an equity award or the exercise of a stock option in an amount up to his maximum individual tax rate, provided that such additional reduction would not result in adverse financial accounting or tax withholding treatment to U.S. Silica.

The severance benefits and the treatment of equity awards of the named executive officers in the event of termination or a change in control are discussed in more detail below in Potential Payments Upon Employment Termination or Change in Control.

Executive Compensation Policies

Stock Ownership Guidelines

To more closely align the interests of our executive officers, including our named executive officers, with our shareholders, in February 2014, the Compensation Committee adopted stock ownership guidelines to require our executive officers to acquire and hold our common stock with a value equal to the following multiples of base salary:


Chief Executive Officer		4x base salary
Chief Financial Officer		2x base salary
Chief Operating Officer		2x base salary
Other executive officers		1.5x base salary

Equity that counts towards meeting the stock ownership requirements includes shares owned directly and indirectly and time-vested restricted stock and restricted stock units. Unexercised stock options and unearned performance share units are not counted toward meeting the requirements. Executive officers are required to achieve their stock ownership requirement within five years of becoming subject to the guidelines. The Compensation Committee, in its sole discretion, may require an executive officer to retain up to 100% of the shares acquired upon stock option exercises (after payment of the exercise cost and taxes) or issued upon the vesting of restricted stock, restricted stock units or performance share units (after the payment of taxes) if such officer has failed to meet the stock ownership requirement by the five year deadline.

The table below shows the value of our common stock held by each of our named executive officers as compared to the stock ownership requirement such officer must meet by February 2019 based on such officer’s base salary as of December 31, 2016. The value of each named executive officer’s stock holdings was based on the average closing price of a share of our common stock over the 90 trading days ending February 1, 2017, which was $50.95.


Name	Value of Stock Holdings ($)		Stock Ownership Requirement by February 2019 ($)
Bryan A. Shinn		9,616,150		2,600,000
Donald A. Merril		2,489,774		712,300
Bradford B. Casper		3,890,899		525,000
Michael L. Winkler		3,670,693		816,000
John P. Blanchard		1,750,387		426,300

Hedging and Pledging Policy

Under our Insider Trading Policy, employees including named executive officers are prohibited from selling our securities “short” and from transacting in publicly-traded options, warrants, puts and calls or similar instruments on our securities. Employees, including our named executive officers, also are prohibited from holding our stock in a margin account or pledging our stock as collateral for a loan without obtaining approval from the General Counsel or Chief Compliance Officer. An exception to the prohibition against pledging may be granted when the employee clearly demonstrates the financial capacity to repay the loan without resort to any pledged securities. None of our named executive officers have pledged our stock.

Clawback Policy

To further deter excessive risk taking, the Compensation Committee adopted a clawback policy in February 2014 that applies to all executive officers’ annual cash-based performance awards beginning with the 2013 award paid in 2014 and all long-term performance-based awards beginning with those granted in 2014. If any of our financial results are materially restated and an executive officer is determined to have been knowingly engaged in misconduct or grossly negligent in failing to prevent misconduct directly related to such restatement, the Compensation Committee may seek recoupment from such officer of the portion of any performance-based compensation that was greater than that which would have been awarded or earned had such compensation been calculated on the basis of the restated financial results. The determination as to whether the criteria for a claw back has been met will be made by the Compensation Committee.

Tax and Accounting Policies

In determining which elements of compensation are to be paid, and how they are weighted, we also take into account whether a particular form of compensation will be deductible under Section 162(m) of the Internal Revenue Code. Section 162(m) generally limits the deductibility of compensation paid to our named executive officers to $1.0 million during any fiscal year unless such compensation is “performance-based” under Section 162(m). Rights or awards granted, vested or paid under the plan, other than options and stock appreciation rights, will not qualify as “performance-based compensation” for purposes of Section 162(m) unless such rights or awards are granted, vested or paid upon pre-established objective performance goals, the material terms of which are disclosed to and approved by our shareholders.

Our executive compensation program is intended to maximize the deductibility of the compensation paid to our named executive officers but it is not the sole objective when designing the executive compensation program. In certain circumstances, the Compensation Committee may authorize compensation arrangements that are not fully tax deductible, but that promote other important objectives, such as attracting and retaining executives who can drive financial and strategic growth objectives that maximize long-term shareholder value. For example, if we had not achieved sales of at least $200 million in 2016, the Compensation

Committee, at its discretion, could have provided awards to executive officers that would not have been pursuant to the 2016 ABIP. Such awards would not have been considered performance-based and potentially would not have been tax-deductible, but which could have been determined based on the degree of achievement of various performance metrics as well as other factors taken into consideration by the Compensation Committee.

Many other Internal Revenue Code provisions (including Section 409A), SEC regulations and accounting rules affect the payment of executive compensation and are generally taken into consideration as programs are developed.

2016 Summary Compensation Table

The following table presents information concerning the total compensation for the last three years of (1) individuals who served as our principal executive officer or principal financial officer during 2016 and (2) our three most highly compensated executive officers, other than our principal executive officer and principal financial officer, who were serving as executive officers at the end of our fiscal year ended December 31, 2016 (the “named executive officers”).

The restricted stock units vest ratably over a three-year period beginning one year from the date of grant.

The amounts disclosed for the performance share units reflect the fair value as of the grant date based on an accounting valuation analysis. The performance share units are paid out only if we meet performance objectives established by the Compensation Committee at the beginning of the performance period. Actual payouts will range from 0% to 200% of the amounts shown in the table above. For more information on the performance objectives for these performance share units see the 2016 Long-Term Incentive Program section in Material Elements of Compensation above.

The number of units granted to each named executive officer for each performance period were as follows:


Name	January 1, 2014 – December 31, 2016 (#)		January 1, 2015 – December 31, 2017 (#)		January 1, 2016 – December 31, 2018 (#)		Total (#)

The performance share units are paid out only if we meet performance objectives established by the Compensation Committee at the beginning of the performance period. For more information on applicable performance measures, see Material Elements of Compensation in Compensation Discussion and Analysis. See Potential Post-Employment Payments for a description of the treatment of performance share units in the event that employment is terminated.

No awards were payable under the performance share units related to the performance period from January 1, 2014 through December 31, 2016 because our Adjusted EBITDA performance over that period was below the threshold performance level. No payout is expected under the performance share units related to the performance period from January 1, 2015 through December 31, 2017 because actual performance over the performance period is not anticipated to meet the performance objectives established by the Compensation Committee at the beginning of the performance period.

Potential Payments Upon Employment Termination or Change in Control

Severance Plan

Mr. Shinn’s severance amount is calculated pursuant to the terms of his employment agreement as disclosed in Employment and Other Agreements.

In the event of an involuntary termination without cause not involving a change in control, Messrs. Merril, Casper, Winkler and Blanchard are entitled to cash severance equal to twelve months of base salary and reimbursement of the monthly premium for COBRA healthcare coverage for twelve months in exchange for the executive officer executing a standard release. Each severance arrangement involving an executive officer is subject to the Compensation Committee’s review and approval at the time of termination.

Severance benefits payable to Messrs. Merril, Casper, Winkler and Blanchard in the event of a separation from service as a result of an involuntary termination of employment without cause or resignation for good reason following a change in control of U.S. Silica are disclosed in Employment and Other Agreements.

Amended and Restated 2011 Incentive Compensation Plan

Stock Options

Options granted prior to 2014: All options granted prior to 2014 are fully vested. In the event of voluntary termination or involuntary termination without cause, vested options are exercisable until the earlier of (1) 90 days following termination and (2) the expiration of the stated term of the options. In the event of involuntary termination for cause, all vested options will terminate and expire automatically. In the event of death or disability, all vested options will remain exercisable until the earlier of (1) one year from the date of death or disability and (2) the expiration of the stated term of the options. In the event of a change in control where the consideration paid is all cash, any options that are not exercised as of the occurrence of a change in control will terminate following the change in control.

Options granted in 2014 and 2015: Subject to the Compensation Committee’s discretion to accelerate vesting, all unvested stock options will be forfeited upon a participant’s voluntary termination and vested options are exercisable until the earlier of (1) 90 days following termination and (2) the expiration of the stated term of the options. In the event of termination for cause, all vested and unvested options will terminate and expire automatically. In the event of a participant’s termination by us without cause, the unvested options that would have vested on the next vesting date will vest on a pro rata basis, and all vested options will remain exercisable until the earlier of (1) 90 days following termination and (2) the expiration of the stated term of the options. In the event of a participant’s termination as a result of death or disability or due to the participant’s retirement, the unvested options that would have vested on the next vesting date will vest on a pro rata basis and all vested options will remain exercisable until the earlier of (1) one year from the date of death or disability and (2) the expiration of the stated term of the options. In the event of a participant’s termination as a result of death or disability, by us without cause, as a result of the participant’s resignation for good reason or as a result of the participant’s retirement at any time upon or following a change in control, all unvested options shall become fully vested and remain exercisable for three years (or, in the case of a retirement following a change in control, until the expiration date of the option).

Service-Based Restricted Stock. All restricted stock held by the named executive officers is fully vested.

Service-Based Restricted Stock Units. Subject to the Compensation Committee’s discretion to accelerate vesting, all unvested restricted stock units will be forfeited upon a participant’s voluntary termination or termination for cause. In the event of a participant’s termination as a result of death or disability, by us without cause or due to the participant’s retirement, the unvested restricted stock units that would have vested on the next vesting date will vest on a pro rata basis. In the event of a participant’s termination as a result of death or disability, by us without cause, as a result of the participant’s resignation for good reason or as a result of the participant’s retirement at any time upon or following a change in control, all unvested restricted stock units shall become fully vested.

Performance Share Units. Subject to the Compensation Committee’s discretion to accelerate vesting, all performance share units will be forfeited upon a participant’s voluntary termination or termination for cause. In the event of a participant’s termination as a result of death or disability, by us without cause or due to the participant’s retirement, the performance shares units will remain outstanding until the Compensation Committee certifies the level of performance for the performance period and the performance share units will become vested based on actual performance on a pro rata basis. In the event of a participant’s termination as a result of death or disability, by us without cause, as a result of the participant’s resignation for good reason or as a result of the participant’s retirement at any time upon or following a change in control, all performance share units shall become vested based on the target level of performance.

Under our CIC Plan and Amended and Restated 2011 Incentive Compensation Plan, a change in control is deemed to have occurred upon:

•

a change in the composition of the Board from the beginning of any period of two consecutive years such that the existing Board or persons who were approved by two-thirds of directors or their successors on the existing Board no longer constitute a majority at the end of such period;

•

the acquisition by a person of 50% or more of our voting securities;

•

the completion of certain mergers, consolidations, share exchanges or similar transactions involving us;

•

the completion of the sale of all or substantially all of our assets; or

•

our liquidation or dissolution.

Under our CIC Plan and equity award agreements, a named executive officer’s resignation would be for “good reason” following:

•

a material reduction in the named executive officer’s annual base salary;

•

a required relocation of more than 50 miles from the named executive officer’s primary place of employment; or

•

a material, adverse change in the named executive officer’s title, reporting relationship, authority, duties or responsibilities.

In addition, any breach by us of Mr. Shinn’s employment agreement would enable Mr. Shinn to resign for good reason.

The information below describes and quantifies certain compensation that would become payable to our named executive officers if, as of December 31, 2016, their employment with us had been terminated or there had been a change in control of U.S. Silica. None of our named executive officers was eligible for retirement as of December 31, 2016. Due to the number of factors that affect the nature and amount of any benefits provided upon the events discussed below, any actual amounts paid or distributed may be different. Factors that could affect these amounts include the timing during the year of any such event.

Reflects the value of equity awards owned by the named executive officer where vesting is accelerated by the triggering event as described above in Benefit Plan Provisions Related to Employment Termination or Change in Control—Amended and Restated 2011 Incentive Compensation Plan. For stock options, this represents the in-the-money value as of December 31, 2016. For stock awards, this represents the fair market value of shares using $56.68 (closing price per share of our common stock on December 31, 2016). For performance share units, no payout is assumed upon employment termination other than in connection with a change in control for the performance share units covering the performance periods from January 1, 2014 through December 31, 2016 and January 1, 2015 through December 31, 2017 because actual performance over those performance periods is not expected to trigger a payout. For the performance share units covering the performance period from January 1, 2016 through December 31, 2018, a payout at target is assumed upon employment termination other than in connection with a change in control although the actual payout will depend on actual performance over the performance period. All performance share units would be paid out at target following a change in control with a qualifying termination. Assumes the Compensation Committee has not otherwise accelerated vesting.

Director Compensation

We did not pay Mr. Shinn, who also is our Chief Executive Officer, for his service as a director.

In January 2014, the Compensation Committee (then the Compensation and Governance Committee), with the assistance of management and Exequity, benchmarked our non-employee directors’ mix of compensation and amount of each element of compensation to the outside director compensation reported by the following peer companies, which were the same as the 2014 proxy peer group used for executive compensation benchmarking purposes:


AMCOL International Corporation		Intrepid Potash, Inc.
C&J Energy Services, Inc.		ION Geophysical Corporation
Carbo Ceramics Inc.		PDC Energy Inc.
Clayton Williams Energy, Inc.		Pioneer Energy Services Corp.
Comstock Resources Inc.		Resolute Energy Corporation
Eagle Materials Inc.		TETRA Technologies, Inc.
EPL Oil & Gas, Inc.		Texas Industries, Inc.
GulfMark Offshore, Inc.

The Compensation Committee did not benchmark director compensation or make any changes to the director compensation program in 2016. The Compensation Committee intends to benchmark director compensation in 2017 and approximately every other year thereafter. For 2016, the compensation for the non-employee members of the Board consisted of the following:

•

annual Board retainer of $60,000, payable in quarterly installments;

•

annual Chairman of the Board retainer of $50,000, payable in quarterly installments;

•

annual Audit Committee Chairman retainer of $20,000, payable in quarterly installments;

•

annual retainer of $15,000 to the Chairmen of the Compensation Committee, Nominating and Governance Committee and Executive Committee, payable in quarterly installments;

•

annual committee retainer of $10,000 for each committee on which a non-employee member of the Board serves (other than as chairman), payable in quarterly installments;

•

a restricted stock unit award in an amount determined by aggregating the amounts set forth below in each category for which a director is eligible for a grant, such award to vest one year following the date of grant subject to pro rata forfeiture if the director terminates Board service before the vesting date


Category	Amount of Grant
Eligible Board member	$	90,000
Chairman of the Board	$	50,000
Audit Committee Chairman	$	20,000

Stock Ownership Requirements

As disclosed in Stock Ownership, each of our non-employee directors owns shares of our common stock. Under stock ownership guidelines, originally adopted by the Compensation Committee in February 2014 and amended in February 2017, each non-employee director is required to acquire and maintain holdings of our common stock, which includes restricted stock units, equal to at least five times the director’s annual director cash retainer within five years of becoming subject to the requirement.

REPORT OF COMPENSATION COMMITTEE

The Compensation Committee of the Board has reviewed and discussed the Compensation Discussion and Analysis beginning on page 17 with management. Based on such review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the Proxy Statement for the 2017 annual meeting of shareholders.

COMPENSATION RISK ASSESSMENT

We have conducted a comprehensive analysis of the risk profile of our employee and executive compensation policies and programs, and determined that the risks arising from our compensation policies and programs are not reasonably likely to have a material adverse effect on our company. This comprehensive risk assessment was conducted by our management, with assistance from the Compensation Committee’s compensation consultant. Management’s risk assessment was presented to the Compensation Committee in March 2017.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Our directors, executive officers and beneficial owners of more than 10% of the shares of our common stock are required to file initial reports of ownership and reports of changes of ownership of our common stock with the Securities and Exchange Commission. Based upon a review of these filings and written representations from our directors, executive officers and beneficial owners of more than 10% of the shares of our common stock, all required filings were timely made.

PROPOSAL NO. 2: RATIFICATION OF GRANT THORNTON LLP AS

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2017

Vote Required; Recommendation of the Board of Directors

Approval of the proposal to ratify Grant Thornton LLP as our independent registered public accounting firm for the year 2017 requires the affirmative vote of a majority of shares present in person or represented by proxy at the annual meeting and entitled to vote, assuming a quorum is present. Abstentions will have the same effect as a vote against the proposal and broker non-votes will not have any effect on the results of the vote.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR APPROVAL OF THIS PROPOSAL.

PROPOSAL NO. 3: ADVISORY VOTE ON COMPENSATION OF NAMED

EXECUTIVE OFFICERS

Executive Compensation Philosophy

At our 2016 annual meeting, approximately 80% of the votes cast were in favor of the say-on-pay proposal. We believe the voting results demonstrated strong support for the overall design and results of our compensation program in 2015, which included strong alignment between pay and performance. For 2016, the overall design of our executive compensation program remained largely unchanged with the exception of removing stock options from the mix of equity awards granted as part of the long-term incentive program and changing the performance measure for the long-term performance share units from cumulative Adjusted EBITDA to relative total shareholder return as compared to a peer group, as discussed in Compensation Discussion and Analysis.

In 2016, a significant portion of the compensation of our Chief Executive Officer and other named executive officers consisted of cash and equity incentive compensation contingent upon the achievement of financial performance, as measured by Adjusted EBITDA, business unit and/or individual performance goals, and the performance of our common stock relative to our peers. Performance-based compensation aligns the interests of our Chief Executive Officer and other named executive officers with the interests of our shareholders because the amount of compensation ultimately received will vary with our financial performance. Additionally, our equity compensation, in the form of stock options, performance share units and restricted stock units, derives its value from our equity value, which is likely to fluctuate based on our financial performance.

We believe that the 2016 compensation of our named executive officers was appropriate and aligned with our 2016 strategic objectives and performance. We encourage you to read the Compensation Discussion and Analysis section of this Proxy Statement beginning on page 17, which describes in more detail our compensation philosophy and the policies and procedures that have been designed to achieve our compensation objectives, as well as the Summary Compensation Table and other related compensation tables, notes and narrative, beginning on page 34 of this Proxy Statement, which provide detailed information on the compensation of our named executive officers.

Vote Required; Recommendation of the Board of Directors

We are requesting shareholders to approve the following non-binding, advisory resolution at the 2017 annual meeting of shareholders:

RESOLVED, that the shareholders of U.S. Silica provide their advisory approval of the compensation of U.S. Silica’s named executive officers disclosed in the Compensation Discussion and Analysis, the compensation tables and related notes and narrative contained in the Proxy Statement for U.S. Silica’s 2017 Annual Meeting of Shareholders.

Approval of this advisory proposal requires the affirmative vote of a majority of the votes cast by holders of shares of our common stock present in person or by proxy at the meeting and entitled to vote, assuming a quorum is present. Abstentions will have the same effect as a vote against the proposal and broker non-votes will not have any effect on the results of the vote.

This vote is not intended to address any specific item of compensation, but rather the overall compensation of the named executive officers as described in this Proxy Statement. This vote is advisory and therefore not binding on us or our Board. The Board, however, will review the outcome of this vote and will take it into account in making determinations concerning the compensation of our executive officers in the future.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR APPROVAL OF THIS PROPOSAL.

PROPOSAL NO. 4: AMENDMENT OF OUR SECOND AMENDED AND

RESTATED CERTIFICATE OF INCORPORATION TO REMOVE THE REQUIREMENT

OF PLURALITY VOTING FOR THE ELECTION OF DIRECTORS

Vote Required; Recommendation of the Board of Directors

Amendment of our Second Amended and Restated Certificate of Incorporation to remove the requirement of plurality voting for the election of directors requires the affirmative vote of at least 66 2/3% of all outstanding shares of common stock as of the Record Date. Abstentions and broker non-votes will have the same effect as a vote against the proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR APPROVAL OF THIS PROPOSAL.

Overview

The Nominating and Governance Committee and the Board have carefully considered the advantages and disadvantages of electing directors by a majority vote standard and have determined that it is appropriate to implement majority voting for uncontested director elections through amendments to our Certificate of Incorporation, Bylaws and Corporate Governance Guidelines.

Currently, Section 3 of ARTICLE SIX of our Second Amended and Restated Certificate of Incorporation sets forth the voting standard applicable to the election of directors. It requires that directors be elected by a plurality vote. In plurality voting, the nominees for available directorships who receive the highest number of affirmative votes cast are elected, whether or not such “for” votes constitute a majority of all votes (including those withheld). Conversely, under a majority voting standard, a director nominee is only elected if the number of votes cast “for” the nominee’s election is greater than the number of votes cast “against” that director nominee. Abstentions are not considered votes cast “for” or “against” the nominee. Under such a system, a director nominee in a contested election (one in which the number of director nominees exceeds the number of directors to be elected) would continue to be elected by a plurality of the votes cast.

The Board has approved an amendment to Section 8 of ARTICLE II of the Company’s Bylaws, which would only become effective upon the effectiveness of this amendment to the Certificate of Incorporation. The Bylaw amendment provides for a majority vote standard in uncontested director elections, while retaining a plurality vote standard in the event of a contested election. If the proposed amendment to the Certificate of Incorporation becomes effective, the Bylaw amendment would apply to the election of directors at the Company’s 2018 annual meeting of shareholders. The Board will also amend our Corporate Governance Guidelines to adopt a director resignation policy requiring an incumbent director who is not re-elected under the majority voting standard to tender his or her resignation for the Board’s consideration, which would become effective upon the effectiveness of this amendment to the Certificate of Incorporation and the amendment to the Bylaws.

The text of revised Section 3 of ARTICLE SIX of our Second Amended and Restated Certificate of Incorporation and the proposed deletions indicated by strike-out, are set forth in Annex A to this proxy statement. If approved, this amendment will become effective upon filing with the Secretary of State of the State of Delaware of a certificate of amendment of our Second Amended and Restated Certificate of Incorporation, or a Third Amended and Restated Certificate of Incorporation if Proposal No. 5 is also approved by shareholders. We expect to make such a filing promptly after the annual meeting.

PROPOSAL NO. 5: AMENDMENT OF OUR SECOND AMENDED AND

RESTATED CERTIFICATE OF INCORPORATION TO REMOVE CERTAIN

PROVISIONS RELATING TO OWNERSHIP OF STOCK BY OUR FORMER

CONTROLLING SHAREHOLDER

Vote Required; Recommendation of the Board of Directors

Amendments of our Second Amended and Restated Certificate of Incorporation to repeal provisions relating to the ownership of our stock by our former controlling shareholder that are no longer necessary require the affirmative vote of at least 66 2/3% of all outstanding shares of common stock as of the Record Date for all other amendments. Abstentions and broker non-votes will have the same effect as a vote against the proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR APPROVAL OF THIS PROPOSAL. IF NOT OTHERWISE SPECIFIED, PROXIES WILL BE VOTED FOR APPROVAL OF THIS PROPOSAL.

Overview

The Board recommends that our Second Amended and Restated Certificate of Incorporation be amended to remove certain provisions relating to the ownership of our stock by our former controlling shareholder, Golden Gate Private Equity, Inc. and its affiliates (“Golden Gate Capital”). These provisions provided for certain approval rights and rights relating to the calling of special shareholder meetings and acting by written consent in each case unique to Golden Gate Capital so long as it owned at least 35% of our outstanding shares of common stock and excluded Golden Gate Capital from provisions governing transactions with interested shareholders. Golden Gate Capital ceased to be a shareholder in December 2013, and as a result, the Board believes that these provisions are no longer necessary.

The text of the revisions to our Second Amended and Restated Certificate of Incorporation, and the proposed deletions indicated by strike-out, are set forth in Annex B to this proxy statement. If approved, these amendments will become effective upon filing of a Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware. We expect to make such a filing promptly after the annual meeting.

SUBMISSION OF SHAREHOLDER PROPOSALS

FOR NEXT YEAR

For inclusion in next year’s proxy statement: Any shareholder who desires to include a proposal in our proxy statement for the 2018 annual meeting must deliver it so that it is received by November 24, 2017.

For presentation at the next annual meeting of shareholders: Under our bylaws, any shareholder who wants to propose a nominee for election as a director, or to present any other proposal, at the 2018 annual meeting must deliver the proposal so it is received no later than February 3, 2018 and no earlier than January 4, 2018. Under our bylaws, however, if the date of the 2018 annual meeting is changed so that it is more than 30 days earlier or later than May 4, 2018 any such proposals must be delivered by the later of (1) 10 days following the day on which we first publicly announce the date of the 2018 annual meeting or (2) the date that is 90 days prior to the 2018 annual meeting.
