Who is soliciting my vote?

In this Proxy Statement, the Board is soliciting your vote.

How does the Simpson Board recommend that I vote?

The Simpson Board unanimously recommends that you vote by proxy using the WHITE proxy card with respect to the proposals, as follows:

• FOR the election of all three Board nominees set forth on the WHITE proxy card (Proposal 1);

• FOR the approval of the Company’s amended Executive Officer Cash Profit Sharing Plan (Proposal 2);

We describe all proposals and the Board’s reasons for supporting Proposals 1, 2, 3, and 4, for recommending “1 Year” for Proposal 5, and for opposing Proposal 6, in detail beginning at page [•] of this Proxy Statement.

Who can vote?

Holders of our common stock at the close of business on [•], 2017 may vote at the 2017 Annual Meeting.

As of the date of this Proxy Statement, there are [47,654,058] shares of our common stock outstanding, each entitled to one vote. There are approximately [620] shareholders of record as of the date of this Proxy Statement.

How do I vote if I am a record holder?

You can vote by attending the 2017 Annual Meeting and voting in person, or you can vote by proxy. If you are the record holder of your stock, you can vote by proxy in three ways:

• By Internet: You may vote by submitting a proxy over the Internet. Please refer to the WHITE proxy card or voting instruction form provided to you by your broker for instructions of how to vote by Internet.

• By Telephone: Shareholders located in the United States that receive proxy materials by mail may vote by submitting a proxy by telephone by calling the toll-free telephone number on the WHITE proxy card or voting instruction form and following the instructions.

• By Mail: If you received proxy materials by mail, you can vote by submitting a proxy by mail by marking, dating, signing and returning the WHITE proxy card in the postage-paid envelope.

• In Person at the 2017 Annual Meeting: If you attend the 2017 Annual Meeting, you may deliver your completed WHITE proxy card in person or you may vote by completing a ballot, which we will provide to you at the meeting. You are encouraged to complete, sign and date the WHITE proxy card and mail it in the enclosed postage pre-paid envelope regardless of whether or not you plan to attend the 2017 Annual Meeting.

How do I vote if my common shares are held in “street name”?

If you hold your shares of common stock in “street name,” meaning such shares are held for your account by a broker, bank or other nominee, then you will receive instructions from such institution or person on how to vote your shares. Your broker, bank or other nominee will allow you to deliver your voting instructions via the Internet and may also permit you to submit your voting instructions by telephone.

If you do not provide voting instructions to your bank, broker, trustee or other nominee holding shares of our common stock for you, your shares will not be voted with respect to any proposal, as we do not believe any of the proposals qualify for discretionary voting treatment by a broker. We therefore encourage you to provide voting instructions on a proxy card or a provided voting instruction form to the bank, broker, trustee or other nominee that holds your shares by carefully following the instructions provided in their notice to you.

How many votes do I have?

Shareholders are entitled to one vote for each share of common stock held.

At the special meeting of shareholders that was convened on March 28, 2017, shareholders approved and adopted an amendment to our Certificate of Incorporation to eliminate the ability to exercise cumulative voting in the election of directors. Following the special meeting, on the same day, we filed a certificate of amendment setting forth the amendment with the Office of the Secretary of State of the State of Delaware, which was effective immediately upon such filing, and the Board effected conforming amendments to our Bylaws. As a result, under our amended Certificate of Incorporation, shareholders will not be able to cumulate their votes in the election of directors at the 2017 Annual Meeting.

How will my shares of common stock be voted?

The shares of common stock represented by any proxy card which is properly executed and received by the Company prior to or at the 2017 Annual Meeting will be voted in accordance with the specifications you make thereon. Where a choice has been specified on the WHITE proxy card with respect to the proposals, the shares represented by the WHITE proxy will be voted in accordance with the specifications. If you return a validly executed WHITE proxy card without indicating how your shares should be voted on a matter and you do not revoke your proxy, your proxy will be voted: FOR the election of all three Board nominees set forth on the WHITE proxy card (Proposal 1); FOR the approval of the Company’s amended Executive Officer Cash Profit Sharing Plan (Proposal 2); FOR the ratification the Board’s selection of Grant Thornton LLP as the Company’s independent registered public accountants for the current fiscal year (Proposal 3); FOR the approval, on an advisory, non-binding basis, of the compensation of the Company’s named executive officers (Proposal 4); for the approval, on an advisory, non-binding basis, of 1 YEAR

as the frequency of future advisory votes on the compensation of the Company’s named executive officers (Proposal 5); and AGAINST the non-binding shareholder proposal to declassify the Board (Proposal 6).

What vote is required with respect to the proposals?

Proposal 1, regarding the three directors to be elected, will require approval of a plurality of the votes cast, meaning that the director nominees receiving the highest numbers of “for” votes of the shares entitled to be voted for them, up to the number of directors to be elected by such shares, will be elected. As a result, the three director nominees receiving the most “for” votes at the 2017 Annual Meeting will be elected. The enclosed WHITE proxy card enables a shareholder to vote “FOR” or “WITHHOLD” from voting as to each person nominated by the Board.

Proposals 2, 3, 4, and 6 will be decided by the affirmative vote of a majority of the votes cast. The enclosed WHITE proxy card enables a shareholder to vote “FOR,” “AGAINST” or “ABSTAIN” on these proposals. Each of Proposals 2, 3, 4, and 6 will pass if the total votes cast “for” a given proposal exceed the total number of votes cast “against” such given proposal.

With respect to Proposal 5 regarding the frequency of future advisory votes on the compensation of the Company’s named executive officers, the enclosed WHITE proxy card enables a shareholder to vote “1 Year,” “2 Years” “3 Years” or “ABSTAIN” on this proposal. The choice receiving the largest number of affirmative votes cast, whether or not a majority of the votes has been cast for such choice, shall be the election of the shareholders on Proposal 5.

What is the effect of abstentions and broker non-votes on voting?

Abstentions and broker non-votes, if any, will not constitute votes cast or votes withheld on any of the proposals and will accordingly have no effect on the outcome of the vote on any of the proposals.

If I have already voted by proxy against the proposals, can I still change my mind?

Yes. To change your vote by proxy, simply sign, date and return the enclosed WHITE proxy card or voting instruction form in the accompanying postage-paid envelope, or vote by proxy by telephone or via the Internet in accordance with the instructions in the proxy card or voting instruction form. We strongly urge you to vote by proxy FOR the election of each of the Board’s nominees on Proposal 1, FOR Proposals 2, 3, and 4, FOR 1 YEAR on Proposal 5, and AGAINST Proposal 6. Only your latest dated proxy will count at the 2017 Annual Meeting.

Will my shares be voted if I do nothing?

If your shares of our common stock are registered in your name, you must sign and return a proxy card in order for your shares to be voted, unless you vote over the Internet or by telephone or attend the 2017 Annual Meeting and vote in person.

If your shares of common stock are held in “street name,” that is, held for your account by a broker, bank or other nominee, and you do not instruct your broker or other nominee how to vote your shares, then, because all of the proposals are “non-routine matters,” your broker or other nominee would not have discretionary authority to vote your shares on the proposals. If your shares of our common stock are held in “street name,” your broker, bank or nominee has enclosed a proxy card or voting instruction form with this Proxy Statement. We strongly encourage you to authorize your broker or other nominee to vote your shares by following the instructions provided on the proxy card or voting instruction form.

Please return your proxy card or voting instruction form to your broker or other nominee by proxy, simply sign, date and return the enclosed proxy card or voting instruction form in the accompanying postage-paid envelope, or vote by proxy by telephone or via the Internet in accordance with the instructions in the proxy card or voting instruction form. Please contact the person responsible for your account to ensure that a proxy card or voting instruction form is voted on your behalf.

We strongly urge you to vote by proxy FOR the election of each of the Board’s nominees on Proposal 1, FOR Proposals 2, 3, and 4, FOR 1 YEAR on Proposal 5, and AGAINST Proposal 6 by signing, dating and returning the enclosed proxy card today in the envelope provided. You may also vote by proxy over the Internet using the Internet address on the proxy card or by telephone using the toll-free number on the proxy card. If your

shares are held in “street name,” you should follow the instructions on your proxy card or voting instruction form provided by your broker or other nominee and provide specific instructions to your broker or other nominee to vote as described above.

What constitutes a quorum?

Votes withheld, abstentions and broker non-votes, if any, will be counted as present or represented for purposes of determining the presence or absence of a quorum for this meeting. In the absence of a quorum, the 2017 Annual Meeting may be adjourned by a majority of the votes entitled to be cast represented either in person or by proxy.

Has the Company received notice from one or more shareholders that they are intending to cumulate votes or nominate directors at the 2017 Annual Meeting?

Yes. Iron Compass Partners, LP, which, together with certain affiliates (“Iron Compass”), has indicated that it beneficially owns an aggregate of 170,042 shares of our common stock (representing approximately 0.36% of our outstanding common stock), prior to the March 28, 2017 special meeting of shareholders, delivered notice to the Company of its intention to cumulate votes and to nominate one director candidate, Brett N. Milgrim, for election to the Board at the 2017 Annual Meeting. At the March 28, 2017 special meeting of shareholders, shareholders approved and adopted an amendment to our Certificate of Incorporation to eliminate the ability to exercise cumulative voting in the election of directors. Following the special meeting, on the same day, we filed a certificate of amendment setting forth the amendment with the Office of the Secretary of State of the State of Delaware, which was effective immediately upon such filing, and the Board effected conforming amendments to our Bylaws. As a result, under our amended Certificate of Incorporation, shareholders will not be able to cumulate their votes with respect to any director nominee on Proposal 1 or Iron Compass’ nominee.

Can qualifying shareholders exercise proxy access rights for the 2017 Annual Meeting?

No. The Board amended our Bylaws on March 28, 2017 to provide proxy access to qualifying shareholders effective as of March 28, 2017. Pursuant to our amended Bylaws, the notice period for exercising proxy access rights has already passed for the 2017 Annual Meeting. Shareholders will therefore be able to exercise proxy access rights for the first time at the 2018 annual meeting of shareholders.

Whom should I call if I have questions about the 2017 Annual Meeting?

Proxy Contest of Iron Compass

Iron Compass Partners, LP, together with certain of its affiliates (“Iron Compass”), has notified the Company of its intention to nominate one individual for election as our director at the 2017 Annual Meeting in opposition to the nominees recommended by the Board. You may receive proxy solicitation materials from Iron Compass. The Company is not responsible for the accuracy of any information provided by or relating to Iron Compass or its nominees contained in solicitation materials filed or disseminated by or on behalf of Iron Compass or any other statements that Iron Compass may make. The Board does NOT endorse the Iron Compass nominee and strongly recommends that

you NOT sign or return any proxy card sent to you by Iron Compass. If you have previously voted using a proxy card sent to you by Iron Compass, you can subsequently revoke that vote by following the instructions on the WHITE proxy card to vote over the Internet or by telephone or by completing, signing and dating the enclosed WHITE proxy card and mailing it in the postage pre-paid envelope provided. Only your latest dated proxy will count. Any proxy may be revoked at any time prior to its exercise at the 2017 Annual Meeting as described in the accompanying Proxy Statement.

Proxy Card

The shares represented by any proxy card which is properly executed and received by the Company prior to or at the 2017 Annual Meeting will be voted in accordance with the specifications made thereon. Where a choice has been specified on the WHITE proxy card with respect to the proposals, the shares represented by the WHITE proxy card will be voted in accordance with the specifications. If you return a validly executed WHITE proxy card without indicating how your shares should be voted on a matter and you do not revoke your proxy, your proxy will be voted: FOR the election of all three Board nominees set forth on the WHITE proxy card (Proposal 1); FOR the approval of the Company’s amended Executive Officer Cash Profit Sharing Plan (Proposal 2); FOR the ratification the Board’s selection of Grant Thornton LLP as the Company’s independent registered public accountants for the current fiscal year (Proposal 4); FOR the approval, on an advisory, non-binding basis, of the compensation of the Company’s named executive officers (Proposal 4); for the approval, on an advisory, non-binding basis, of 1 YEAR as the frequency of future advisory votes on the compensation of the Company’s named executive officers (Proposal 5); and AGAINST the non-binding shareholder proposal to declassify the Board (Proposal 6).

The Board is not aware of any matters that are expected to come before the 2017 Annual Meeting other than those described in this Proxy Statement. If any other matter should be presented at the 2017 Annual Meeting upon which a vote may be properly taken, shares represented by all WHITE proxy cards received by the Board will be voted with respect thereto at the discretion of the persons named as proxies in the enclosed proxy card.

Record Date

Only holders of record of common stock at the close of business on [•], 2017 will be entitled to notice of and to vote at the 2017 Annual Meeting.

Quorum

The presence of holders of our common stock having a majority of the votes that could be cast by the holders of all outstanding shares of our common stock entitled to vote at the 2017 Annual Meeting, in person or represented by proxy, will constitute a quorum for the transaction of business at the 2017 Annual Meeting. Votes withheld, abstentions and broker non-votes, if any, will be counted as present or represented for purposes of determining the presence or absence of a quorum for this meeting. In the absence of a quorum, the 2017 Annual Meeting may be adjourned by a majority of the votes entitled to be cast represented either in person or by proxy.

Required Vote

As a holder of our common stock, you are entitled to one vote per share on any matter submitted to a vote of the shareholders.

Our Bylaws require that, in a contested election, directors are elected by a plurality of the votes cast. Since Iron Compass has nominated a person for election to the Board, this election of directors at the 2017 Annual Meeting is considered a contested election. Proposal 1, regarding the three directors to be elected, therefore will require approval of a plurality of the votes cast, meaning that the director nominees receiving the highest numbers of “for” votes of the shares entitled to be voted for them, up to the number of directors to be elected by such shares, will be elected. As a result, the three director nominees receiving the most “for” votes at the 2017 Annual Meeting will be elected.

The enclosed WHITE proxy card enables a shareholder to vote “FOR” or “WITHHOLD” from voting as to each person nominated by the Board. If you vote “withhold” for any director nominee, as opposed to voting “FOR” any such director nominee, your shares voted as such will be counted for purposes of establishing a quorum, but will not be considered to have been voted FOR the director nominee and as such will have no effect the outcome of the vote on Proposal 1. Abstentions and broker non-votes, if any, will not constitute votes cast or votes withheld on Proposal 1 and will accordingly have no effect on the outcome of the vote on Proposal 1.

PLEASE SUPPORT THE BOARD’S NOMINEES BY VOTING “FOR” THE BOARD’S NOMINEES ON PROPOSAL 1 USING THE ENCLOSED WHITE PROXY CARD. DO NOT COMPLETE OR RETURN A PROXY CARD FROM IRON COMPASS, EVEN IF YOU VOTE “WITHHOLD” ON THEIR DIRECTOR NOMINEE. DOING SO MAY CANCEL ANY PREVIOUS VOTE YOU CAST ON THE COMPANY’S WHITE PROXY CARD

At the March 28, 2017 special meeting of shareholders, shareholders approved and adopted an amendment to our Certificate of Incorporation to eliminate the ability to exercise cumulative voting in the election of directors. Following the special meeting, on the same day, we filed a certificate of amendment setting forth the amendment with the Office of the Secretary of State of the State of Delaware, which was effective immediately upon such filing, and the Board effected conforming amendments to our Bylaws. As a result, under our amended Certificate of Incorporation, shareholders will not be able to cumulate their votes in the election of directors at the 2017 Annual Meeting, including with respect to any director nominee on Proposal 1.

Proposals 2, 3, 4, and 6 will be decided by the affirmative vote of a majority of the votes cast. The enclosed WHITE proxy card enables a shareholder to vote “FOR,” “AGAINST” or “ABSTAIN” on these proposals. Any of Proposals 2, 3, 4, and 6 will pass if the total votes cast “for” such proposal exceed the total number of votes cast “against” the proposal.

Abstentions and broker non-votes, if any, will not constitute votes cast on any of Proposals 2, 3, 4, 5, and 6 or “for” or “withhold” with respect to any director nominee on Proposal 1 and will accordingly have no effect on the outcome of the vote on such proposals.

Proposals 4, 5, and 6 are advisory proposals only and are not binding on the Board or the Company.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE ELECTION
OF EACH OF THE BOARD’S NOMINEES ON PROPOSAL 1 USING THE
ENCLOSED WHITE PROXY CARD.

THE BOARD UNANIMOUSLY RECOMMENDS VOTING FOR PROPOSALS 2, 3,
AND 4, FOR 1 YEAR ON PROPOSAL 5, AND AGAINST PROPOSAL 6, USING THE
ENCLOSED WHITE PROXY CARD.

THE BOARD URGES YOU NOT TO SIGN, RETURN OR VOTE ANY PROXY CARD
SENT TO YOU BY IRON COMPASS.

Abstentions and Broker Non-Votes

If you are a beneficial owner holding your shares in “street name” and you do not provide voting instructions to your bank, broker, trustee or other nominee holding shares of our common stock for you, your shares of common stock will not be voted with respect to any proposal for which the shareholder of record does not have “discretionary” authority to vote. You are deemed to beneficially own your shares in “street name” if your shares are held in an account at a brokerage firm, bank, broker-dealer, trust or other similar organization. If this is the case, you will receive a separate voting instruction form with this Proxy Statement from such organization. As the beneficial owner, you have the right to direct your broker, bank, trustee, or nominee how to vote your shares. If you hold your shares in street name and do not provide voting instructions to your broker, bank, trustee or nominee, your shares will not be voted on any proposals on which such party does not have discretionary authority to vote (a “broker non-vote”).

Rules of the New York Stock Exchange (“NYSE”) determine whether proposals presented at shareholder meetings are “discretionary” or “non-discretionary.” If a proposal is determined to be discretionary, your bank, broker, trustee or other nominee is permitted under NYSE rules to vote on the proposal without receiving voting instructions

from you. If a proposal is determined to be non-discretionary, your bank, broker, trustee or other nominee is not permitted under NYSE rules to vote on the proposal without receiving voting instructions from you. A “broker non-vote” occurs when a bank, broker, trustee or other nominee holding shares for a beneficial owner returns a valid proxy, but does not vote on a particular proposal because it does not have discretionary authority to vote on the matter and has not received voting instructions from the shareholder for whom it is holding shares.

Because Iron Compass has initiated a proxy contest, to the extent that Iron Compass provides a proxy card or voting instruction form to shareholders in street name, none of proposals in this Proxy Statement will be discretionary. We encourage you to provide voting instructions on a WHITE proxy card or a provided voting instruction form to the bank, broker, trustee or other nominee that holds your shares by carefully following the instructions provided in their notice to you.

Revocability of Proxy

A shareholder of record who has properly executed and delivered a proxy may revoke such proxy at any time before the 2017 Annual Meeting in any of the four following ways:

• timely complete and return a new proxy card bearing a later date;

• vote on a later date by using the Internet or telephone;

• deliver a written notice to our Secretary prior to the 2017 Annual Meeting by any means, including facsimile, stating that your proxy is revoked; or

• attend the meeting and vote in person.

If you have previously submitted a proxy card sent to you by Iron Compass, you may change your vote by completing and returning the enclosed WHITE proxy card in the accompanying postage pre-paid envelope, or by voting by telephone or via the Internet by following the instructions on the WHITE proxy card. Submitting a proxy card sent to you by Iron Compass will revoke votes you have previously made via the Company’s WHITE proxy card.

If your shares are held of record by a bank, broker, trustee or other nominee other nominee and you desire to vote at the meeting, you may change your vote by submitting new voting instructions to your broker in accordance with such broker’s procedures.

Appraisal Rights

Holders of shares of common stock do not have appraisal rights under Delaware law in connection with this proxy solicitation.

Proxy Access

The Board amended our Bylaws on March 28, 2017 to provide proxy access to qualifying shareholders effective as of March 28, 2017. Pursuant to our amended Bylaws, the notice period for exercising proxy access rights has already passed for the 2017 Annual Meeting. Shareholders will therefore be able to exercise proxy access rights for the first time at the 2018 annual meeting of shareholders.

OTHER INFORMATION

Participants in the Solicitation

Under applicable regulations of the Securities Exchange Commission (the “SEC”), each of our directors and certain of our executive officers and other employees are “participants” in this proxy solicitation. Please refer to the section entitled “Security Ownership of Certain Beneficial Owners and Management” for information about our directors and executive officers. Except as described in this Proxy Statement, there are no agreements or understandings between the Company and any such participants relating to employment with the Company or any future transactions. Other than the persons described in this Proxy Statement, no general class of employee of the Company will be employed to solicit shareholders in connection with this proxy solicitation. However, in the course of their regular duties, employees may be asked to perform clerical or ministerial tasks in furtherance of this solicitation.

Exhibit A attached hereto sets forth additional information relating to our directors and director nominees as well as certain of our officers and employees who are considered “participants” in our solicitation under the rules of the SEC by reason of their position as directors and director nominees of the Company or because they may be soliciting proxies on our behalf.

Costs of Solicitation

We are required by law to convene an annual meeting of shareholders at which directors are elected. Because our shares are widely held, it would be impractical for our shareholders to meet physically in sufficient numbers to hold a meeting. Accordingly, the Company is soliciting proxies from our shareholders. United States federal securities laws require us to send you this Proxy Statement, and any amendments and supplements thereto, and to specify the information required to be contained in it. The Company will bear the expenses of calling and holding the 2017 Annual Meeting and the solicitation of proxies therefor. These costs will include, among other items, the expense of preparing, assembling, printing and mailing the proxy materials to shareholders of record and beneficial owners, and reimbursements paid to brokerage firms, banks and other fiduciaries for their reasonable out-of pocket expenses for forwarding proxy materials to shareholders and obtaining beneficial owner’s voting instructions. In addition to soliciting proxies by mail, directors, officers and employees may solicit proxies on behalf of the Board, without additional compensation, personally or by telephone. We may also solicit proxies by email from shareholders who are our employees or who previously requested to receive proxy materials electronically. As a result of the potential proxy solicitation by Iron Compass, we may incur additional costs in connection with our solicitation of proxies. The Company has retained D.F. King & Co., Inc. (“D.F. King”) to solicit proxies. Under our agreement with D.F. King, D.F. King will receive a fee of up to $[•] plus the reimbursement of reasonable expenses. The reimbursement to D.F. King will not be submitted to a shareholder vote. D.F. King expects that approximately [•] of its employees will assist in the solicitation. D.F. King will solicit proxies by mail, telephone, facsimile or email. Our aggregate expenses, including those of D.F. King, related to our solicitation of proxies, excluding salaries and wages of our regular employees, are expected to be approximately $[•], of which approximately $[•] has been incurred as of the date of this Proxy Statement.

BACKGROUND OF THE SOLICITATION

During 2015, members of the Board and the senior management team engaged in extensive dialogue with shareholders, which led to a comprehensive review of the Company’s executive compensation program and governance practices during 2016 and informed a number of compensation program changes for 2016. During this review period, the Board continued to engage extensively with shareholders related to changes under consideration. Shareholder feedback was regularly presented to the Board during this review period and shareholder feedback was reflected in the significant compensation and governance changes that were announced in the second half of 2016 and first quarter of 2017. In addition, as part of this comprehensive review and in furtherance of the Company’s long-term strategy, the Board engaged in extensive discussions regarding board composition, culminating in the engagement of Veaco Group, an independent corporate governance advisor, in May 2016 to conduct a skills assessment and “gap” analysis of the current board to assist the Board in developing appropriate criteria for selection of new members of the Board.

On November 10, 2015, Karen Colonias (our Chief Executive Officer and a member of the Board), Brian J. Magstadt (our Chief Financial Officer, Treasurer and Secretary) and Thomas J Fitzmyers (our current Vice Chairman of the Board) met with Matthew S. Kupersmith and James L. Hegyi of Iron Compass in Chicago, Illinois, while Ms. Colonias and Messrs. Magstadt and Fitzmyers were attending the Baird Industrial Conference. Based on its nomination notice dated February 7, 2017, Iron Compass has indicated that it beneficially owns an aggregate of 170,042 shares of our common stock, representing approximately 0.36% of our outstanding common stock.

On December 3, 2015, Iron Compass distributed a presentation to Ms. Colonias and Mr. Magstadt addressing the Company’s operating margins and profitability and certain recommended structural changes in the management of costs and administrative expenses.

On March 11, 2016, representatives of Iron Compass and the Company discussed Iron Compass’s request to meet with the Board at the time of the Company’s 2016 annual meeting of shareholders, and the Company agreed to schedule a meeting for Iron Compass to meet with Peter N. Louras, Jr. (our Chairman of the Board) on the day before the annual meeting.

On April 19, 2016, representatives of Iron Compass met with Mr. Louras, Mr. Magstadt and Ms. Colonias and distributed a new presentation, which Mr. Louras circulated to the Board, reasserting Iron Compass’ beliefs regarding the Company’s operations and expense structure.

On April 20, 2016, representatives of Iron Compass attended the Company’s 2016 annual meeting of shareholders. At its Board meeting held on the same date, the Board reviewed and discussed the materials prepared by Iron Compass.

On April 25, 2016, Iron Compass made a request to present to the Board at its meeting to be held in July. On May 4, 2016, Iron Compass reiterated its request to present to the Board and distributed a new presentation to Mr. Louras, which Mr. Louras circulated to the Board, presenting certain case studies. On June 13, 2016, following additional correspondence between the Company and Iron Compass, Mr. Louras informed Iron Compass that the Board had declined Iron Compass’s request to present at the July Board meeting. On June 16, 2016, Mr. Louras spoke to representatives of Iron Compass by telephone to discuss the Board’s decision.

On July 6, 2016, Iron Compass issued a letter to the Board, which, among other things, outlined certain of Iron Compass’ suggestions for making structural changes relating to the Company’s commercial construction and truss plate business, selling, general and administrative expenses, capital allocation, and return of capital to shareholders. The Board reviewed and discussed the letter during its scheduled July Board meetings.

On August 1, 2016, Iron Compass issued a press release making its July 6 letter public.

On August 24, 2016, the Company issued a press release and filed a Form 8-K with the SEC announcing that the Board, on August 19, 2016, increased and extended its previous share repurchase authorization as well as authorized the Company to execute accelerated share repurchase programs in support of the authorization.

On the same date, the Board sent a letter to Iron Compass in response to Iron Compass’s July 6 letter. On August 31, Iron Compass responded to the Board’s letter, acknowledging disagreements with management regarding the balance sheet and capital allocation.

On October 25, 2016, the Company filed a Form 8-K with the SEC disclosing that, following extensive shareholder outreach by the Board and management during 2015 and the first half of 2016 as part of a comprehensive review of the

Company’s executive compensation program and governance practices, the Company was making significant changes to its executive compensation program, incentive structure, and governance practices, including the termination of its shareholder rights plan.

On November 4, 2016, Iron Compass submitted a shareholder proposal to the Company for presentation to shareholders at the 2017 Annual Meeting, requesting that the Board “take all necessary steps (other than any steps that must be taken by shareholders) to eliminate the classification of the Board and to require that all directors elected by shareholders be elected on an annual basis commencing with the first annual meeting of shareholders for the election of directors occurring after the elimination of the Board classification, notwithstanding that any director may have been elected for a term that extends beyond such annual meeting.”

On January 19, 2017, Iron Compass sent a letter to the Company notifying us of its intention to nominate one or more individuals for election to the Board at the 2017 Annual Meeting and elect for cumulative voting and requesting certain materials required for making a formal notice.

On January 25, 2017, as part of the Board’s ongoing succession planning and refreshment process, the Company announced that Thomas J Fitzmyers notified the Company that he decided to retire as Vice Chairman of the Board at the end of his current term at the 2017 Annual Meeting. As a result, Mr. Fitzmyers would continue to serve on the Board until the 2017 Annual Meeting but agreed not to stand for re-election to the Board at the 2017 Annual Meeting.

The Company also announced at such time that the Governance and Nominating Committee was undertaking an ongoing board evaluation and director succession planning process and was actively engaged in a search for a new independent director to fill the vacancy created by Mr. Fitzmyers’ retirement, utilizing the services of Veaco Group and Korn Ferry, an independent executive and director search firm it had retained in September 2016. Between November 2016 and March 2017, the Governance and Nominating Committee evaluated a number of potential independent director candidates identified by Korn Ferry, including Michael A. Bless. The Governance and Nominating Committee and the full Board conducted multiple telephonic and in-person interviews of director candidates during this period.

On January 26, 2017, following correspondence between the Company, Iron Compass and the SEC regarding certain legal defects with respect to Iron Compass’ shareholder proposal, Iron Compass submitted a revised shareholder proposal to us, which provided that the implementation of the proposal would not affect the unexpired terms of directors elected prior to such implementation, while still requesting the Board declassification and annual election of directors at the first annual meeting of shareholders occurring after the implementation of the proposal.

On January 27, 2017, Mr. Louras, along with Mr. Magstadt, Ms. Colonias and Robin G. MacGillivray (the Chair of the Governance and Nominating Committee), held a telephone conference with representatives of Iron Compass in which Iron Compass indicated that it intended to nominate Brett N. Milgrim as a director candidate at the 2017 Annual Meeting.

On January 30, 2017, after careful deliberation about the implications of declassifying the Board in conjunction with shareholders having the ability to exercise cumulative voting in the election of directors, and in line with broad shareholder feedback, the Board resolved to hold a special meeting of shareholders on or about March 28, 2017 at which shareholders would be permitted to approve amendments to our Certificate of Incorporation to (1) declassify the Board over a three-year period and elect directors who are up for re-election and new director candidates annually beginning at the 2017 Annual Meeting, and (2) eliminate the ability to exercise cumulative voting in the election of directors. On January 31, 2017, the Company issued a press release and filed a Form 8-K with the SEC, announcing the special meeting and the Board’s decision.

On February 3, 2017, Iron Compass issued a press release expressing certain of its views regarding the March 28, 2017 special meeting.

On February 6, 2017, Iron Compass delivered notice to the Company of its intention to cumulate votes and to nominate Mr. Milgrim as a director candidate for election to the Board at the 2017 Annual Meeting.

On February 8, 2017, Mr. Kupersmith of Iron Compass emailed Mr. Louras requesting a meeting in Aspen, Colorado. While not available for an in-person meeting, Mr. Louras responded that the Company was open to a telephonic meeting with Iron Compass.

On February 10, 2017, the Company filed a preliminary proxy statement with the SEC for the March 28, 2017 special meeting.

On February 16, 2017, in response to Mr. Kupersmith’s February 8 request, Mr. Louras and Ms. MacGillivray had a telephonic meeting with Mr. Kupersmith. Following this conversation, Mr. Louras emailed Mr. Kupersmith indicating the Board’s intent to include Mr. Milgrim in its Board refreshment process by having him go through the same process used during the past year with other Board candidates but on an accelerated timetable.

On February 22, 2017, the Board committed to amend our Bylaws to provide proxy access to qualifying shareholders after the March 28, 2017 special meeting.

On February 23, 2017, the Company filed a definitive proxy statement with the SEC in connection with the March 28, 2017 special meeting and announced, in a press release and a Form 8-K filed with the SEC, that the 2017 Annual Meeting would be rescheduled to May 16, 2017. In the following weeks, each of the three leading independent proxy advisory firms, ISS, Glass Lewis, and Egan-Jones, recommended that shareholders vote in favor of both the Company’s declassification and cumulative voting proposals at the March 28, 2017 special meeting.

On March 1, 2017, Korn Ferry conducted an interview of Iron Compass’ proposed director nominee, Mr. Milgrim.

On March 16, 2017, Ms. MacGillivray and James S. Andrasick, both members of the Governance and Nominating Committee, conducted an interview with Mr. Milgrim in San Jose, California.

On March 17, 2017, after careful deliberation, and upon the recommendation of the Governance and Nominating Committee, the Board unanimously agreed to nominate Mr. Bless for election to the Board at the 2017 Annual Meeting.

On March 19, 2017 Mr. Bless accepted his nomination to the Board.

On March 20, 2017, the Company filed with the SEC its preliminary proxy statement for the 2017 Annual Meeting.

On March 28, 2017, the Company held a special meeting of shareholders to vote on approving and adopting amendments to our Certificate of Incorporation to (1) declassify the Board over a three-year period and provide that directors who are up for election be elected to one-year terms beginning at the 2017 Annual Meeting, and (2) eliminate the ability to exercise cumulative voting in the election of directors. At the special meeting, shareholders approved both proposals. Following the special meeting, on the same date, the Company filed a certificate of amendment setting forth the amendments with the Office of the Secretary of State of the State of Delaware to immediately give effect to the amended Certificate of Incorporation, and the Board resolved to amend our Bylaws to (1) conform the Bylaws to the amended Certificate of Incorporation, and (2) provide proxy access for qualifying shareholders effective March 28, 2017. Pursuant to our amended Bylaws, the notice period for exercising proxy access rights has already passed for the 2017 Annual Meeting. Shareholders will therefore be able to exercise proxy access rights for the first time at the 2018 annual meeting of shareholders.

On the same date, the Company filed with the SEC Amendment No. 1 to its preliminary proxy statement for the 2017 Annual Meeting.

Core skills and experiences represented by continuing members of the Board and the new Board director nominee are included in the summary graphic below:

The current composition of the Board and its director nominees reflect director-selection criteria developed by the Nominating and Governance Committee to address the needs and priorities of the Company and satisfy certain regulatory requirements. See “Director Selection Criteria” below.

Board Nominees

The Board, on the recommendation of its Governance and Nominating Committee, which is composed only of independent members of the Board, has nominated our incumbent directors Karen Colonias and Celeste Volz Ford, whose terms are currently set to expire at the 2017 Annual Meeting, for re-election to the Board. The Board, on the recommendation of its Governance and Nominating Committee, has additionally nominated a new director candidate, Michael A. Bless, for election to the Board at the 2017 Annual Meeting. Mr. Bless was originally identified to the Governance and Nominating Committee as a potential new director through a search conducted with the assistance of Korn Ferry, a third-party executive search and recruiting firm engaged by the Governance and Nominating Committee to identify and evaluate potential director candidates. The Board recommends that shareholders vote to elect each of Ms. Colonias, Ms. Ford and Mr. Bless to hold office until the election and qualification of directors at the 2020 annual meeting of shareholders. Pursuant to the Company’s Certificate of Incorporation and Bylaws, any new director candidate and each of our incumbent directors who are up for re-election will be elected at the 2017 Annual Meeting for a 3-year term expiring upon the election and qualification of directors at the annual meeting of shareholders to be held in 2020.

Each of Ms. Colonias, Ms. Ford and Mr. Bless has consented to be named in this Proxy Statement and to serve as a director if elected. Unless otherwise instructed, the persons named as proxies in the enclosed proxy card will vote the proxies received by them for the three Board nominees. The Board knows of no reason why any of the nominees named in this Proxy Statement would be unable or for good cause will not serve, but if any nominee should for any reason be unable to serve or for good cause will not serve, the Board reserves the right to nominate substitute nominees for election prior to the 2017 Annual Meeting, in which case the Company will file an amendment to this Proxy Statement disclosing the identity of such substitute nominees and related information and the proxies received will be voted for such substitute nominees.

We have received a notice from Iron Compass expressing its intent to nominate one individual for election to the Board at the 2017 Annual Meeting in opposition to the Board nominees named in this Proxy Statement. Iron Compass has indicated that it beneficially owns an aggregate of 170,042 shares of our common stock (representing approximately 0.36% of our outstanding common stock). The Governance and Nominating Committee carefully evaluated the individual proposed by Iron Compass, along with certain other persons. We believe that the nominees proposed by the Board are the most qualified candidates up for election at the 2017 Annual Meeting because they have the key attributes that are important to an effective board, including the experience, industry knowledge, integrity and commitment necessary to oversee the execution of our strategic plan and create value for all our shareholders. See “Board of Director Information” below. As a result, the Board does not endorse the Iron Compass nominee and unanimously recommends that you vote FOR the Board nominees who have been named in this Proxy Statement and on the WHITE proxy card. THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU DO NOT SIGN, OR OTHERWISE VOTE USING, ANY PROXY CARD SENT TO YOU BY IRON COMPASS. IF YOU HAVE PREVIOUSLY SIGNED, OR OTHERWISE VOTED USING, A PROXY CARD SENT TO YOU BY IRON COMPASS, YOU CAN REVOKE IT BY SIGNING, DATING AND MAILING THE ENCLOSED WHITE PROXY CARD IN THE ENVELOPE PROVIDED.

Board Nominee and Director Qualifications and Biographical Information

Our directors are individuals of reputation, integrity and accomplishment. They bring to the Board a range of expertise, talents and insights. In addition, they bring practical industry experience in a variety of areas. See “Composition of the Board” above. As is required by our Governance Guidelines, a majority of our outside (non-management) directors must be independent. To be independent, a director must have no financial, family or close personal ties to us or our executive officers and must meet the New York Stock Exchange (“NYSE”) independence standards. See “Board Independence” below. We undertake serious and deliberate consideration to evaluate periodically our current directors’ skill sets and are committed to Board refreshment and succession planning. For prospective director candidates, we seek individuals with qualifications and attributes that are complementary to our business, industry, strategy and current directors’ skills and experience. See “Director Selection Criteria” below.

Mr. Fitzmyers has informed us that he will retire following the end of his current term at the 2017 Annual Meeting.

Required Vote

Our Bylaws require that, in a contested election, directors are elected by a plurality of the votes cast, which means that the director nominees receiving the highest numbers of “for” votes of the shares entitled to be voted for them, up to the number of directors to be elected by such shares, will be elected. Since Iron Compass has nominated an individual for election to the Board, the election of directors at the 2017 Annual Meeting is considered a contested election. At the 2017 Annual Meetings, our shareholders will vote to elect three directors. As a result, among the three Board nominees and the Iron Compass nominee, the three individuals receiving the most “for” votes casted at the 2017 Annual Meeting will be elected to the Board. The enclosed WHITE proxy card enables a shareholder to vote “FOR” or “WITHHOLD” as to each person or all three individuals nominated by the Board. If you vote “withhold” for any Board nominee, as opposed to voting “FOR” all three Board nominees, your shares will be counted for purposes of establishing a quorum, but will not be considered to have been voted FOR such nominee. Same applies if you vote “withhold” for all Board nominees. Abstentions and broker non-votes, if any, will not constitute the votes cast either “for” or “withhold” with respect to a nominee and will accordingly have no effect on the outcome of the election of directors at the 2017 Annual Meeting.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU USE THE WHITE PROXY CARD TO VOTE “FOR” THE ELECTION OF ALL THREE BOARD NOMINEES, KAREN COLONIAS, CELESTE VOLZ FORD AND MICHAEL A. BLESS, TO THE BOARD AT THIS ANNUAL MEETING.

BOARD INFORMATION AND PRACTICES

Board Diversity

While the Company does not have a formal policy with regard to diversity in identifying director nominees, the Board believes that the backgrounds and qualifications of directors, considered as a group, should provide a significant composite mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities. The Board, half of whom are women, consists of directors with a variety of backgrounds. We do not discriminate against nominees on the basis of race, color, religion, gender, gender identity or expression, sexual orientation, age, national origin, disability, covered veteran status, or any other status protected by law.

Director Tenure

The Board currently believes that a robust board evaluation process — one focused on the assessment and alignment of director skills with company strategy and priorities — is more effective than relying solely on age or tenure limits to achieve board refreshment. Therefore, we do not have a fixed retirement age for directors. Under our Governance Guidelines updated in 2016, no outside director will be nominated for re-election after 20 years of board service, and the Board generally will not nominate outside directors who come on Board after 2016 for re-election after 15 years of board service. If all three Board nominees, including Mr. Bless, are elected to the Board at the 2017 Annual Meeting, the average tenure of our directors will be 7 years. Board tenure of continuing members of the Board, including our CEO, and the new Board director nominee following the 2017 Annual Meeting (if the new nominee was elected to the Board) is broken into three groups as indicated in the summary graphic below:

Board Self-Assessment and Third-Party Evaluation

The Board has a regular practice of assessing the diversity of skill sets of its members, the alignment of areas of expertise with the Company’s strategy and priorities, and stewardship of company performance.

In recognition of the Board’s commitment to regular evaluation, and in light of planned board member retirement, during 2016, the Board engaged, Veaco Group, an independent third-party corporate governance consulting firm, to conduct an assessment of the Board to help evaluate the current skills and experiences and identify key attributes for new director candidates based on the Company’s current strategy and priorities. Veaco Group’s evaluation process included reviewing public filings, director surveys, board and committee materials and processes, and prior board evaluations as well as engaging each Board member and members of senior management with tailored written questions and oral interviews. The results of this evaluation were provided to the Governance and Nominating Committee for it to develop, on an informed basis, selection criteria for identifying, screening and recommending potential director candidates. In addition to the Board’s annual evaluations of its own and its committees’ functioning and operations, Veaco Group carried out an independent review of the Board’s functioning and overall effectiveness. Based on the Veaco Group’s independent review, the Board believes that it and its committees are currently functioning effectively.

Director Selection Criteria

In selecting director candidates, the Board seeks to achieve a mix of members who collectively bring significant value to the Company through their experience and personal backgrounds relevant to the Company’s strategic priorities and the scope and complexity of the Company’s business and industry. In light of the Company’s strategic priorities, and based on its self-assessment and a corporate governance consultant’s evaluation (see “Board Self-Assessment and Third-Party Evaluation” below), the Board identified key skills and experiences for director candidates that included current public company senior executive and public company board experience in managing a diversified enterprise, industry experience or understanding, an appreciation of the impacts of rapidly changing technologies and experience in managing and expanding business outside of the United States, especially in Europe. To complement its oversight responsibilities, the Board also identified implementing or overseeing company growth, strategy development, mergers and acquisitions and operations experience as key Board skills.

Based on this guidance, the Governance and Nominating Committee, working closely with the full Board and outside advisors, has developed a list of current criteria for nominating director candidates for open positions on the Board. In developing these criteria, the Governance and Nominating Committee took into account a variety of factors, including the current composition of the Board, the current strategy and future outlook of the Company, the range of experience and skills that would best complement those already represented on the Board, and the need for specialized expertise. Below are the skills and experiences that the Governance and Nominating Committee currently identifies as most valuable to the Board:

• Current Public Company Senior Executive Leadership Experience,

• Asset Management and Capital Markets Expertise,

• Strategy Experience,

• Public Company Board Experience,

• Mergers & Acquisitions Experience,

• Financial Expertise,

• International Operations Experience,

• Industry Experience,

• Corporate Governance Experience,

• Risk Management Experience,

• Talent Management and Human Resource Experience, and

• Technology Experience.

The Governance and Nominating Committee also believes that the following attributes, qualities and skills are important for our Board members to possess:

• Good judgment,

• Ability to identify issues and ask constructive questions,

• Ability to communicate effectively and have a positive relationship with management and fellow Board members,

• Ability to think critically and be a collegial disrupter,

• Concurrence with our deep commitment to shareholders and address their concerns,

• Ability to contribute to the development of forward-looking strategies, and

• Ability to manage conflict.

Based on Veaco Group’s report and in light of the Company’s current priorities, the Governance and Nominating Committee recommended to the Board that the ideal prospective director candidate should have the following attributes: Current Chief Executive Officer, Chief Financial Officer or other senior executive officer of a public company in the same or a related industry (such as construction materials, manufacturing or distribution industries) with financial acumen, given the Board’s financial oversight responsibilities, public company board experience and experience with strategy development, leading company growth and managing international operations.

Director Selection Process

The Governance and Nominating Committee has retained, Korn Ferry, a leading executive search and recruiting firm, to identify and/or review new candidates upon request of the Governance and Nominating Committee. The Governance and Nominating Committee also considers new candidates for Board membership suggested by its members, other Board members, management, and shareholders.

Once a prospective candidate has come to the Governance and Nominating Committee’s attention, including candidates recommended by its advisors or suggested by shareholders, the Governance and Nominating Committee evaluates the candidate’s leadership, boardroom, transaction and industry experience, financial, management and technology expertise, business acumen, strategic ability as well as interpersonal skills, teamwork, vision and integrity, against the desired director attributes, and makes an initial determination as to whether to conduct a full evaluation. In making this determination, the Governance and Nominating Committee takes into account the information provided to it with the recommendation of the candidate, as well as the Governance and Nominating Committee’s own knowledge and information obtained through inquiries to third parties to the extent the Governance and Nominating Committee deems appropriate. The preliminary determination is based primarily on the current need for additional Board members and the likelihood that the prospective candidate can satisfy the criteria that the Governance and Nominating Committee has established (See “Director Selection Criteria” above). If the Governance and Nominating Committee determines, in consultation with the Chairman of the Board and other directors as appropriate, that additional consideration is warranted, it may request its executive search and recruiting advisor to gather additional information about the prospective candidate’s background and experience and to report its findings to the Governance and Nominating Committee. The Governance and Nominating Committee then evaluates the prospective candidate against the Board selection criteria that it has developed, as well as the following factors:

• the extent to which the prospective candidate contributes to the range of talent, skill and expertise appropriate for the Board;

• the prospective candidate’s willingness to comply with our governance policies and guidelines, including our compensation recovery policy, our anti-hedging and anti-pledging policy, and our Governance Guidelines (which include our stock ownership guidelines for outside directors) (See “Corporate Governance — Governing Documents” below).

• the prospective candidate’s willingness to represent the interests of all of the Company’s shareholders;

• the prospective candidate’s commitment to integrity and independence of thought and judgment;

• the prospective candidate’s ability to dedicate sufficient time, energy and attention to the diligent performance of his or her duties and avoid conflict of interest, including his or her current board memberships; and

• the prospective candidate’s ability to resonate with the company value, structure and culture developed by the Company’s founder, Barclay Simpson, and at the same time, appreciate the Company’s growth potential.

If the Governance and Nominating Committee decides, on the basis of its preliminary review, to proceed with further consideration, members of the Governance and Nominating Committee, as well as other members of the Board as appropriate, then reach out to interview the candidate. After completing its evaluation, the Governance and Nominating Committee makes a recommendation to the full Board, which makes the final determination whether to nominate or appoint the new candidate after considering the Governance and Nominating Committee Committee’s recommendation.

Pursuant to our Bylaws, a shareholder who wishes to recommend a prospective candidate for the Board to us may notify the Company’s Secretary in writing with materials and information required by our Bylaws and other supporting materials that the shareholder considers appropriate. In considering whether to nominate any person suggested by a shareholder, the Governance and Nominating Committee will evaluate such candidate in the same way as it evaluates director candidates identified by itself.

In making its recommendations with respect to the nomination for re-election of existing directors at our annual meetings of shareholders, the Governance and Nominating Committee assessed the current composition of the Board and considered the extent to which the Board continues to reflect the criteria set forth above. The “Composition of the Board” section sets out how each of the current Board members contributes to the mix of experience, skills and qualifications that we seeks to be represented on the Board.

New Director Nominee

As a part of the Board’s succession plan, when Mr. Fitzmyers’ announced his retirement following the 2017 Annual Meeting, we planned to nominate a new independent director candidate to be elected to the Board at the 2017 Annual Meeting. Through its ongoing board evaluation and director succession planning process, the Governance and Nominating Committee had been actively conducting searches to identify qualified candidates who would enhance the collective experience and expertise of the Board, including identifying the candidate to fill the vacancy created by Mr. Fitzmyers’ retirement.

Korn Ferry, the executive search and recruiting firm engaged by the Governance and Nominating Committee, through extensive searches, identified and performed reference check and background investigation on several potential director candidates. Members of the Governance and Nominating Committee, as well as other members of the Board as appropriate, reviewed their qualifications, evaluated them against the same selection criteria discussed under “Director Selection Criteria” above, and interviewed some of the candidates, including the candidate nominated by Iron Compass.

Following a rigorous vetting and selection process, the Governance and Nominating Committee recommended Michael A. Bless, current Chief Executive Officer and board member as well as former Chief Financial Officer of Century Aluminum Company, a global producer of primary aluminum, for election to the Board at the 2017 Annual Meeting. Prior to joining Century Aluminum, Mr. Bless served as Managing Director of M. Safra & Co., Chief Financial Officer of Maxtor Corporation and Chief Financial Officer of Rockwell Automation, Inc., and was responsible for the finance, accounting, treasury, investor relations and information technology functions. Mr. Bless’ experience in driving growth and leading major companies, as both Chief Executive Officer and Chief Financial Officer, brings valuable leadership, industry, risk-management, investor-relation, international operations experience and strategy-development experience to the Board. Prior to holding a number of senior management positions at public and private companies, Mr. Bless spent years in investment banking, working for Merrill Lynch and Dillon, Read & Co. in a variety of areas, including mergers and acquisitions, equities, fixed income and restructurings. His business insights, financial acumen and expansive knowledge of the construction materials industry and global market conditions enhance the collective corporate governance, strategic growth and financial expertise of the Board. Applying the NYSE independence standards, the Board has affirmatively determined that Mr. Bless is independent in that he has no material relationship with us, either directly or as a partner, shareholder, officer or employee of an organization that has a relationship with us.

During its evaluation and interview with the individual nominated by Iron Compass, the Governance and Nominating Committee identified that he has been a long-time board member of one of our significant customers, which the Governance and Nominating Committee believed could create conflicts of interest if he were to be elected to the Board. Due to this concern, the Governance and Nominating Committee determined that he is not best suited to be a member of the Board at this time.

We believe that our director nominees for the 2017 Annual Meeting, consisting of three Chief Executive Officers ((1) our own Chief Executive Officer, Ms. Colonias, (2) the Chief Executive Officer of Stellar Solutions, Inc., Ms. Ford and (3) the Chief Executive Officer of Century Aluminum Company, Mr. Bless,), represent highly experienced and qualified Directors, that collectively with our other Board members provide effective oversight and governance of the Company, and evaluate all opportunities for building sustainable value without commitments to implement a pre-determined agenda.

Board Independence

The NYSE listing standards require that the board of directors of a listed company consist of a majority of independent directors. A majority of our current directors are independent under those rules.

The Board follows the independence standards required by the NYSE to determine our directors and Board nominees’ independence. Those standards generally provide, among other tests, that a director will not be independent of a listed company if:

• the director is, or has been within the last 3 years, an employee of the listed company, or an immediate family member is, or has been within the last 3 years, an executive officer, of the listed company;

• the director has received, or has an immediate family member who has received, during any 12-month period within the last 3 years, more than $120,000 in direct compensation from the listed company, other than director and committee fees and pension or other forms of deferred compensation for prior service, provided such compensation is not contingent in any way on continued service;

• the director is a current partner or employee of a firm that is the company’s internal or external auditor;

• the director has an immediate family member who is a current partner of such a firm;

• the director has an immediate family member who is a current employee of such a firm and personally works on the listed company’s audit;

• the director or an immediate family member was within the last 3 years a partner or employee of such a firm and personally worked on the listed company’s audit within that time;

• the director or an immediate family member is, or has been within the last 3 years, employed as an executive officer of another company where any of the listed company’s present executive officers at the same time serves or served on the other company’s compensation committee; or

• the director is a current employee, or an immediate family member is a current executive officer, of another company that has made payments to, or received payments from, the listed company for property or services in an amount that, in any of the last 3 fiscal years, exceeded the greater of $1,000,000 or 2% of consolidated gross revenues of the other company and its parent and subsidiary entities in a consolidated group.

For purposes of these standards, “immediate family member” includes a director’s spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and anyone, other than any domestic employee, who shares the director’s home.

Applying the NYSE independence standards, based on their completed questionnaires provided to the Board, the Board has determined that Mr. Andrasick, Ms. Chatman, Mr. Cusumano, Ms. Ford, Mr. Louras, Ms. MacGillivray and Mr. Bless are each independent in that none of them has a material relationship with us, either directly or as a partner, shareholder, officer or employee of an organization that has a relationship with us. The Board has determined that Ms. Colonias is not independent under those standards. As a result, among the three Board nominees for election at the 2017 Annual Meeting, Ms. Ford and Mr. Bless are independent, and Ms. Colonias is not independent. In making its determination, the Board considered all relevant facts and circumstances, including commercial, industrial, banking, consulting, legal, accounting, charitable and familial relationships, and considered the issue not merely from the standpoint of a director, but also from that of persons or organizations with which a director has an affiliation. If all three Board nominees are elected to the Board at the 2017 Annual Meeting, the percentage of independent directors on

the Board will be 87%, and Ms. Colonias, our CEO, will be the only non-independent director sitting on the Board, as indicated in the summary graphic below.

Director Orientation and Education

New directors are oriented to our business and governance through meetings with our officers and directors and visits to our facilities. We also support, and pay for, participation in continuing education programs to assist directors in performing their Board responsibilities.

BOARD COMMITTEES

Board Committee Membership Summary

The table below sets forth continuing directors’ Board committee membership as of December 31, 2016:

Compensation and Leadership Development Committee

The Compensation and Leadership Development Committee is responsible for the development and review of our compensation policy for all of our salaried employees, including equity-based compensation, and is responsible for reviewing and approving the compensation discussion and analysis for inclusion in our Annual Reports on Form 10-K and/or our proxy statements. The Compensation and Leadership Development Committee currently comprises 4 independent directors, as determined pursuant to the NYSE listing standards and Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, the members of the Compensation and Leadership Development Committee are both:

• “non-employee directors” — directors who satisfy the requirements established by the Securities and Exchange Commission (the “SEC”) for non-employee directors under Rule 16b-3 under the Exchange Act; and

• “outside directors” — directors who satisfy the requirements established under Internal Revenue Code section 162(m).

The Board currently appoints the members of the Compensation and Leadership Development Committee for indefinite terms and may remove any member from the Compensation and Leadership Development Committee at any time. The Compensation and Leadership Development Committee operates under a written charter that the Board adopted, which is also available on our website at http://www.simpsonmfg.com/social-responsibility/governance/compensation.html. We will provide a printed copy of the charter to any shareholder on request.

Compensation and Leadership Development Committee Interlocks and Insider Participation

The Compensation and Leadership Development Committee currently comprises Jennifer A. Chatman, as its Chair, Gary M. Cusumano, Celeste Volz Ford and Peter N. Louras, Jr., all of whom are independent directors. Ms. Chatman, Mr. Cusumano, Ms. Ford and Mr. Louras have no relationships with us or any of our subsidiaries, other than as members of the Board and its committees.

None of the members of the Board who served on the Compensation and Leadership Development Committee in 2016 was ever an officer or employee of the Company or of any of its subsidiaries or since the beginning of 2016 was a participant in a related person transaction that requires disclosure under Item 404 of Regulation S-K adopted by the SEC. During 2016, none of the Company’s executive officers served on the board of directors, its compensation committee or any similar committee of another entity (not including tax-exempt entities under the Internal Revenue Code Section 501(c)(3)) that has one or more of its executive officers serving on the Board or the Compensation and Leadership Development Committee.

Compensation Consultant

The Compensation and Leadership Development Committee has the authority under its charter to retain or obtain the advice of advisers, including compensation consultants, as it may deem appropriate. In accordance with this authority, since 2014, the Compensation and Leadership Development Committee has engaged Mercer LLC (“Mercer”) as its independent compensation consultant to provide it with objective and expert analyses, advice and information with respect to executive compensation. All executive compensation services provided by Mercer were conducted under the direction or authority of the Compensation and Leadership Development Committee. In addition to Mercer, members of our Human Resources and Finance Departments support the Compensation and Leadership Development Committee in its work.

During 2016, Mercer made recommendations to the Compensation and Leadership Development Committee to (1) position the total compensation of the Company’s Named Executive Officers at the median level within a group of updated peer companies when the Company has a median performance; and (2) adjust the framework of the Company’s non-equity incentive and equity incentive compensation programs to effectuate such pay positioning. See “Compensation Discussion and Analysis — Executive Summary” below. Taking into account, among other considerations, the feedback received by the Board from our shareholders, the latest guidelines from proxy advisors, and peer companies’ practices, the Compensation and Leadership Development Committee incorporated these recommendations into the equity-based compensation program for our Named Executive Officers, beginning with equity-based compensation awarded in 2017 for operating and strategic goals achieved for 2016. See “Executive Compensation Analysis — Long-Term Equity Awards” below. We paid Mercer total fees of $494,309 for these services in 2016.

The engagement of Mercer was the result of a selection process, conducted by management and the chair of the Compensation and Leadership Development Committee, among three firms. At the conclusion of the selection process, Mercer was recommended and the Compensation and Leadership Development Committee approved Mercer’s selection. The Compensation and Leadership Development Committee considered the required independence factors outlined by the SEC and NYSE rules. Mercer was engaged in 2016 to:

• identify an updated industry peer group,

• assess the appropriateness and competitiveness of our compensation programs as compared to compensation programs maintained by the selected industry peer group,

• evaluate our executive and director compensation, and

• recommend changes to our short-term and long-term incentive programs.

Mercer was also engaged to perform additional services to evaluate long-term equity compensation and conduct compensation benchmarking analysis for all employees and we paid them $54,685 for these services in 2016. Since 2010 we have engaged Mercer US Inc. and Mercer Health and Benefits LLC for the placement of our health care insurance and Marsh USA Inc. for the placement of our various lines of business insurance, all of the three entities are affiliates of Mercer. In 2016, we paid Mercer US Inc. and Mercer Health and Benefits LLC $1,850. In 2016, we paid Marsh USA Inc. $3,814,274, either directly by us or through commissions paid by our insurance carriers, including $335,000 for brokerage fees and $3,479,274 for insurance policy premiums. The decision to engage Mercer US Inc., Mercer Health and Benefits LLC and Marsh USA Inc. was made by management, not subject to approval by the Board or the Compensation and Leadership Development Committee.

Report of the Compensation and Leadership Development Committee

The Compensation and Leadership Development Committee reviewed the above Compensation Discussion and Analysis, discussed it with our officers, and based on such review and discussions, recommended its inclusion in this Proxy Statement.

Audit Committee

The Audit Committee is responsible for financial and accounting oversight and risk management. Its policies and practices are described below.

Composition

The Audit Committee comprises 4 independent directors, as determined pursuant to the NYSE listing standards and Rule 10A-3 of the Exchange Act. It operates under a written charter that the Board adopted, which is available on our website at http://www.simpsonmfg.com/social-responsibility/governance/audit.html. We will provide a printed copy of the charter to any shareholder on request. The current members of the Audit Committee are James S. Andrasick, as its Chair, Jennifer A. Chatman, Peter N. Louras, Jr. and Robin G. MacGillivray. The Board has determined that each of them meets the definitions and standards for independence and is financially literate, and that James S. Andrasick and Peter N. Louras, Jr., have financial management expertise as required by NYSE listing standards and meet the SEC definition of an “audit committee financial expert.”

Responsibilities

The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the accounting firm that we engage as our independent registered public accounting firm. The Audit Committee must pre-approve fees to be paid to our principal independent registered public accounting firm before it begins work. Our officers are responsible for our internal controls and financial reporting process. Subject to the Audit Committee’s oversight, our independent registered public accounting firm is responsible for performing an independent audit of our internal controls over financial reporting, for performing an independent audit of our consolidated financial statements in accordance with generally accepted auditing standards, and for reporting on those audits.

Report of the Audit Committee

The Audit Committee met 7 times in 2016 and has held discussions with our officers and Grant Thornton LLP (“Grant Thornton”), a registered public accounting firm and our independent registered public accounting firm. Our officers represented to the Audit Committee that our consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States. The Audit Committee has reviewed and discussed the consolidated financial statements with our officers and Grant Thornton. The Audit Committee has discussed with Grant Thornton the matters that are required to be discussed under Auditing Standard No. 16, “Communications with Audit Committees,” issued by the Public Company Accounting Oversight Board.

The Audit Committee has received the written disclosures and the letter from Grant Thornton as required by applicable requirements of the Public Company Accounting Oversight Board affirming the registered public accounting firm’s independence in compliance with Rule 3526. The Audit Committee discussed with Grant Thornton that firm’s independence. On that basis, the Audit Committee believes that Grant Thornton is independent.

Based on the Audit Committee’s discussions with our officers and Grant Thornton, the Audit Committee’s review of the representations of our officers, and the report of Grant Thornton, to the Audit Committee, the Audit Committee recommended that the Board include the audited consolidated financial statements in our Annual Report to Shareholders on Form 10-K for the year ended December 31, 2016, as filed with the SEC. The Audit Committee believes that it has satisfied its responsibilities under its charter.

Governance and Nominating Committee

The Board has a standing Governance and Nominating Committee, which is primarily responsible for nominating candidates to the Board. It operates under a written charter that the Board adopted, which is available on our website at http://www.simpsonmfg.com/social-responsibility/governance/governance.html. We will provide a printed copy of the charter to any shareholder on request. The 3 current members of the Governance and Nominating Committee, Robin G. MacGillivray, Chair, James S. Andrasick and Gary M. Cusumano, are independent and meet all applicable independence requirements under the NYSE listing standards and Rule 10A-3 of the Exchange Act.

The Governance and Nominating Committee considers all candidates identified as potential directors, including those submitted by shareholders for its consideration. Any of our shareholders can recommend a director candidate to the Governance and Nominating Committee by following instructions stated below.

When evaluating a director candidate, whether or not recommended by a shareholder, the Governance and Nominating Committee uses for guidance our Governance Guidelines (available on our website at http://www.simpsonmfg.com/social-responsibility/governance/governance-guidelines.html), including the guidelines’ “Director Qualification Standards” and “Key Director Responsibilities” sections, and considers the candidate’s education, business experience, financial expertise, industry experience, business acumen, interpersonal skills, vision, teamwork, integrity, strategic ability and customer focus. The Governance and Nominating Committee will review and discuss potential candidates who come to its attention, whether from internal or external sources. From the review and discussion, the Governance and Nominating Committee may narrow the list of potential candidates and interview the remaining candidates. The Governance and Nominating Committee will recommend for consideration by the full Board any candidate that the Governance and Nominating Committee considers to be suitable.

Our Bylaws permit our shareholders directly to nominate directors for election at an annual meeting. To do so, a shareholder must notify our Secretary at least 75 days, but not more than 90 days, before the annual meeting, unless we do not publicly disclose the date of the meeting at least 85 days before the date that the meeting is scheduled to be held, in which case our Secretary must receive the shareholder’s notice within 10 days after we publicly disclose the meeting date. Shareholders may make nominations to the Company by writing a letter to:

Simpson Manufacturing Co., Inc.

Board of Directors Governance and Nominating Committee

5956 W. Las Positas Blvd.

Pleasanton, CA 94588

A shareholder’s nomination notice must state as to each of its candidates -

• the candidate’s name, age, business address and residence address,

• the candidate’s principal occupation or employment,

• the number of shares of our common stock that the candidate beneficially owns and other information, if any, required by our Bylaws,

• any other information relating to the candidate that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, pursuant to Regulation 14A under the Exchange Act (including, without limitation, the candidate’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected); and

• a description of all direct and indirect compensation and other material monetary agreements, arrangements and understandings during the past three years, and any other material relationships, between or among such shareholder and shareholder associated person, if any, and their respective affiliates and associates, or others acting in concert therewith, on the one hand, and each proposed nominee, and his or her respective affiliates and associates, or others acting in concert therewith, on the other hand, including, without limitation, all information that would be required to be disclosed pursuant to Item 404 or any other provision of Regulation S-K, if the shareholder making the nomination and any shareholder associated person on whose behalf the nomination is made, or any affiliate or associate thereof or person acting in concert therewith, were the “registrant” for purposes of such Regulation S-K and the nominee were a director or executive officer of such registrant.

The shareholder’s notice must also state its name and address, as they appear on our books, and the number of shares of our common stock that the shareholder beneficially owns and other information, if any, required by our Bylaws.

In addition, each person whom a shareholder proposes to nominate for election as our director must have previously delivered to our Secretary at our principal executive offices a written questionnaire with respect to the background and qualification of such proposed nominee and a written representation and agreement, both in form provided by our Secretary upon written request, that such proposed nominee (i) genuinely intends to serve, once elected, as our director for the entire term for which he or she is standing for election, (ii) is not and will not become a party to (x) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such proposed nominee, if elected as our director, will act or vote on any issue or question that has not been disclosed to the Company or (y) any such voting commitment that limit or interfere with such proposed nominee’s ability to comply, if elected as a director of the Company, with such proposed nominee’s fiduciary duties under applicable law, (iii) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than us with respect to any direct or indirect compensation, reimbursement or indemnification in connection with candidacy, service or action as a director that has not been disclosed to the Company and (iv) if elected as our director, will comply with all our applicable corporate governance, conflict of interest, confidentiality, compensation recovery, stock ownership, and hedging, pledging and trading policies and guidelines.

We will disregard a purported nomination that does not comply in all respects with our Bylaws. In addition, under our Bylaws, if the nominating shareholder, or its qualified representative, does not appear at the meeting to present the proposed nomination, such proposed nomination shall not be considered (unless otherwise required by law to be considered).

We have received a nomination notice from a shareholder with respect to one director candidate for the 2017 Annual Meeting.

Meeting Attendance

In 2016, the Board held 9 meetings, and its committees held a total of 33 meetings, including 7 meetings of the Audit Committee, 11 meetings of the Compensation and Leadership Development Committee, 10 meetings of the Governance and Nominating Committee and 5 meetings of the Acquisition and Strategy Committee.

In 2016, each of our directors attended at least 75% of the aggregate of the total number of meetings of the Board and the total number of meetings of the Board committee(s) on which he or she served.

Although we do not have a policy that requires our directors to attend annual meetings of our shareholders, all of our current directors attended the 2016 annual meeting of our shareholders. In 2016, outside directors of the Board held 3 meetings in executive session on days when regular meetings of the entire Board were scheduled and no meetings in executive session on days when the entire Board did not meet.

Executive Sessions of Outside Directors

Pursuant to the NYSE listing standards, our non-management directors meet at regularly scheduled executive sessions without members of management. In 2016, Chairman of the Board, Mr. Louras, presided over these executive sessions.

CORPORATE GOVERNANCE

The Board believes in sound corporate governance practices that preserve and enhance our long-term value. The following chart highlights our key governance practices, which include several governance changes that have recently been approved and adopted by the Board prior to the 2017 Annual Meeting:

Proxy Access

On February 22, 2017, the Board, based on shareholder feedback, consultation with outside advisors, and its own review, committed to amend our Bylaws to provide proxy access to qualifying shareholders after the March 28, 2017 special meeting, on terms and conditions substantially similar to the following:

• The total number of shareholder nominees for election to the Board to be included in the Company’s proxy materials for an annual meeting of the shareholders shall not exceed the greater of (i) two, or (ii) 20% (rounded down) of the total number of directors of the Board then in office;

• Only shareholders who have continuously held a number of shares representing at least 3% of the outstanding shares of common stock of the Company for at least three years as of both the record date of the annual meeting for which the Company’s proxy materials are being sent and the date of their nomination notice to the Company may have the ability to request the Company to include their director nominations in such proxy materials; and

• A group of no more than 20 shareholders may aggregate their shares to satisfy the above-described ownership threshold.

Governing Documents

The Board has adopted our Governance Guidelines, which set forth the framework within which the Board, assisted by its committees, directs the affairs of the Company. The Governance Guidelines address, among other things, qualifications of directors, director independence, stock ownership by and compensation of Directors, responsibilities, operations and leadership of the Board, management succession and review as well as annual performance evaluation of the Board. The Board has adopted a Code of Business Conduct and Ethics Policy, which are applicable to all employees of the Company and its subsidiaries, including our Chief Executive Officer and our Chief Financial Officer. In addition, during 2016, the Board has adopted a Compensation Recovery Policy, which is applicable to all our current or former executive officers and other covered employees, and an Anti-Hedging and Anti-Pledging Policy, which is applicable to directors, officers, and employees of the Company and its subsidiaries, and such persons’ designees. Each committee of the Board of Directors is governed by a charter adopted by the Board. The Governance Guidelines, the Code of Business Conduct and Ethics Policy, the Compensation Recovery Policy, the Anti-Hedging and Anti-Pledging Policy and each of the committee charters are available on our Investor Relations website under the “Governance” heading at http://www.simpsonmfg.com/social-responsibility/governance. If we amend any aforementioned document, the amendment will be posted at the same location on our website. We will provide a printed copy of any aforementioned document, without charge, to any shareholder who requests it from our Secretary.

Leadership Structure

Since before our initial public offering in 1994, the roles of Chairman of the Board and our Chief Executive Officer have been separated. We believe that this is appropriate under current circumstances, because it allows management to make the operating decisions necessary to manage the business, while helping to keep a measure of independence between the oversight function of the Board and operating decisions. We feel that this has provided an appropriate balance of operational focus, flexibility and oversight.

In 2014, Peter N. Louras, Jr., was appointed as Chairman of the Board. Because an independent director currently serves as Chairman of the Board, we do not separately have a Lead Independent Director. Mr. Louras, as Chairman of the Board, has assumed the duties that were previously performed by the Lead Independent Director, which include participating in setting the agenda of Board and Committee meetings, coordinating the distribution and presentation of meeting materials, facilitating communications among members of the Board and between the Board and management, leading the Board self-evaluation process, and maintaining the focus and punctuality of Board and Committee meetings. In addition, the Chairman’s role also includes leading the efforts in evaluating our Chief Executive Officer and in succession planning, considering Board committee membership and leadership, and presiding at annual meetings of shareholders.

The Board’s Role in Risk Management

The Board and its committees take an active role in overseeing management of our risks. The Board regularly reviews information regarding our operational, financial, legal and strategic risks. Its Compensation and Leadership Development Committee is responsible for overseeing the management of risks relating to our compensation plans; its Audit Committee oversees management of our financial and cyber security risks; and its Governance and Nominating Committee manages risks associated with the independence of the Board and potential conflicts of interest. In 2009, the Board created the Acquisition and Strategy Committee, whose role in risk management, includes evaluating and managing our strategic risks. While each committee is responsible for evaluating certain risks and overseeing the management of these risks, our entire Board is regularly informed about such risks through committee and executive officer reports.

Communications with the Board

We encourage shareholders and interested parties to communicate any concerns or suggestions directly to the independent members of the Board, by writing to:

Board of Directors

Simpson Manufacturing Co., Inc.

P.O. Box 1394

Alamo, CA 94507-7394

PROPOSAL 2
APPROVAL OF OUR AMENDED EXECUTIVE
OFFICER CASH PROFIT SHARING PLAN

At the 2017 Annual Meeting, we will ask our shareholders to consider a proposal to approve our amended Executive Officer Cash Profit Sharing Plan (the “EOCPS Plan”). The proposed changes to the EOCPS Plan will:

(1) give the Compensation and Leadership Development Committee more flexibility in deciding when awards will be made to the covered officers with respect to a fiscal year, instead of making fixed quarterly awards; and

(2) further limit the maximum amount of award may be paid to a covered officer with respect to a particular fiscal year.

Summary of the EOCPS Plan

The Board adopted the EOCPS Plan on January 14, 2003, and our shareholders approved it on March 31, 2003. The Board previously amended the EOCPS Plan on February 25, 2008. Our shareholders approved the amended EOCPS Plan on April 23, 2008, and re-approved it on April 23, 2013.

The EOCPS Plan applies to any employee of the Company treated as a “covered employee” pursuant to 162(m) of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and any other employee designated by the Compensation and Leadership Development Committee. The EOCPS Plan is designed to (1) parallel our Cash Profit Sharing Plan maintained for qualified employees other than our executive officers and provide cash awards for our executive officers and any other employee designated by the Compensation and Leadership Development Committee, and (2) meet, at the same time, the requirements of Internal Revenue Code section 162(m) for the cash awards to be fully deductible as “performance-based compensation” in excess of the $1,000,000 limit for each covered employee. This $1,000,000 limit does not, however, apply to compensation that we pay under a plan approved by our shareholders, if the compensation is “performance-based.”

The Board has delegated the administration of the EOCPS Plan to the Compensation and Leadership Development Committee. The Compensation and Leadership Development Committee determines the amount of the award that each of the covered officers is eligible to receive under the EOCPS Plan. The Compensation and Leadership Development Committee has discretion to reduce or eliminate any award under the EOCPS Plan.

A more detailed description of the EOCPS Plan and our related compensation practices is provided under the “Executive Compensation” below.

2016 Cash Awards under the EOCPS Plan

The amounts that a covered officer will receive under the EOCPS Plan in the future, if any, are in the discretion of the Compensation and Leadership Development Committee and therefore cannot be determined in advance. A “New Plan Benefits” table is not included for this reason. The following table sets forth the amounts that were received by the following individuals and groups as indicated under the EOCPS Plan with respect to the fiscal year ended December 31, 2016.

Name and Position of Individual or Description of Group	Year	Cash Awards ($){1}
Karen Colonias, President, Chief Executive Officer and Director	2016	$	1,860,346	{2}

Brian J. Magstadt, Chief Financial Officer, Treasurer and Secretary	2016	$	788,374

____________

{1} The actual payout to the applicable NEO in the table above was the sum of the 2016 quarterly payouts made to his or her under our EOCPS Plan.

{2} To improve pay and performance alignment with the peer group, the Compensation and Leadership Development Committee exercised its discretion in the second and third quarters of 2016 and reduced the amount of the quarterly payout to Karen Colonias by $300,000 and $500,000, respectively.

{3} Includes cash awards paid to our Vice President, Sunny H. Leung.

Awards paid to each of our NEOs under the EOCPS Plan with respect to each of the three years ended December 31, 2016 are set forth in the “Summary Compensation Table” below.

EOCPS Plan Amendments

At its meetings on October 19, 2016 and on March 17, 2017, the Board, at the recommendation of its Compensation and Leadership Development Committee, authorized further amending the EOCPS Plan (the “EOCPS Plan Amendments”), which will only become effective if and when our shareholders approve the EOCPS Plan Amendments at the 2017 Annual Meeting.

The Board has approved and adopted EOCPS Plan Amendments and believes that approval of the EOCPS Plan Amendments is in our and our shareholders’ best interests. Once the EOCPS Plan Amendments are approved by our shareholders, we will be able to substantially deduct, for federal income tax purposes, performance-based incentive compensation that we pay to each of the covered officers in excess of the $1,000,000 limit to the extent that the other requirements of Internal Revenue Code section 162(m) are satisfied.

Pursuant to the EOCPS Plan Amendments, instead of making quarterly awards, any award under the EOCPS Plan will be paid at such time as determined by the Compensation and Leadership Development Committee; provided that all awards thereunder with respect to periods within a fiscal year shall be paid by March of the succeeding fiscal year.

The EOCPS Plan Amendments require the Compensation and Leadership Development Committee to base performance goals on one or more of the following criteria for making awards under the EOCPS Plan: (i) earnings;

(ii) unit sales, sales volume or revenue; (iii) sales growth; (iv) stock price (including comparison with various stock market indices); (v) return on equity; (vi) return on investment; (vii) total return to shareholders; (viii) economic profit (including gross or net profit); (ix) debt rating; (x) operating income; (xi) cash flows; (xii) cost targets; (xiii) return on assets or margins; or (xiv) implementation, completion or attainment of measurable objectives with respect to (1) software development, (2) new distribution channels, (3) customer growth targets, (4) acquisition identification and integration, (5) manufacturing, production or inventory targets, (6) new product introductions, (7) product quality control, (8) accounting and reporting, (9) recruiting and maintaining personnel, or (10) compliance or regulatory program targets. Such defined group of goals is similar to the group of performance goals used under the Company’s current equity incentive plan.

Under the amended EOCPS Plan, just as it did in the past for the quarterly awards under the current EOCPS Plan last amended in 2008, the Compensation and Leadership Development Committee will base the determination of periodic awards to a covered officer on his or her applicable individual percentage of the amount (each, a “Qualified Amount”) by which the performance goal, as chosen by the Compensation and Leadership Development Committee, with respect to the Company or the employee’s relevant branch or subsidiary for the applicable period exceeds a qualifying level determined by the Compensation and Leadership Development Committee for that period. The Compensation and Leadership Development Committee determines the qualifying level and each covered employee’s individual percentage with respect to a specific period. In doing so, the Compensation and Leadership Development Committee bases the covered employees’ individual percentages on their then-current job functions.

In addition to the existing limitation that no award in excess of $2,500,000 may be paid to any covered officer under the EOCPS Plan with respect to any fiscal year, the EOCPS Plan Amendments add an additional restriction that, with respect to a particular fiscal year, no award in excess of two times any covered officer’s target annual payout for that year will be paid to such officer under the EOCPS Plan. When assessing whether the $2,500,000 cap and/or the two-times cap under the amended EOCPS Plan have been crossed, all awards made to a covered officer with respect to periods within the same fiscal year will be calculated together.

The EOCPS Plan Amendments do not affect any of the awards made under the EOCPS Plan for 2016, including the awards for the fourth quarter of 2016 (which was paid out in early 2017). If the Company’s shareholders approve the EOCPS Plan Amendments, the amended EOCPS Plan will apply to awards to be made after the end of 2016. The first award under the amended EOCPS Plan is expected to be made after the first quarter of 2017 following the 2017 Annual Meeting. In the event that shareholders do not approve the EOCPS Plan Amendments at the 2017 Annual Meeting, the Company’s current EOCPS Plan, last amended on February 25, 2008, will continue in effect with respect to awards to be made after the end of 2016.

In the event that our shareholders do not approve the EOCPS Plan Amendments, the EOCPS Plan, last amended on February 25, 2008, will continue in effect with respect to awards thereunder to be made for 2017 and future years, until further amendments to such EOCPS Plan our shareholders approve.

EOCPS Plan Implementation for 2017

To implement the amended EOCPS Plan for 2017, the Compensation and Leadership Development Committee determined previously in October 2016 that, subject to the approval of the EOCPS Plan Amendments by our shareholders at the 2017 Annual Meeting, the awards under the EOCPS Plan for 2017 will be made through five payments, with each of the first four payments to be made quarterly and the last payment to be made at the end of 2017 (or thereafter by March, 2018). For each of the four quarters in 2017, an executive Officer will receive the awards based on 50% of his or her applicable individual percentage of the respective quarterly Qualified Amount. As for the last payment, the executive officer will receive the awards based on 50% of his or her applicable individual percentage of the annual Qualified Amount for 2017. The net effect of such five payments is to reduce the amount of quarterly awards and proportionately increase the amount of awards to be made following the end of the year, with the year-end awards contingent upon achieving the Qualified Amount for the entire year.

In February, 2017, the Compensation and Leadership Development Committee also determined to use 2017 qualified operating profit of our primary operating subsidiary, Simpson Strong-Tie Company Inc., as the EOCPS Performance Goal for 2017 and base the determination of periodic awards to an executive officer in 2017 under the amended EOCPS Plan on his or her applicable individual percentage of the amount of that EOCPS Performance Goal in excess of a specified qualifying level. Such EOCPS Performance Goal uses the same methodology that was used in 2016 and prior fiscal years to measure Qualified Amounts under the current EOCPS Plan last amended in 2008.

EOCPS Plan as Amended

A copy of the EOCPS Plan, as amended by the EOCPS Plan Amendments, is attached to this Proxy Statement as Exhibit B, with additions of text indicated by underlining and deletions of text indicated by strike-outs, and is incorporated herein by this reference. The foregoing description of the EOCPS Plan and the EOCPS Plan Amendments is only a summary and is qualified in its entirety by reference to the actual text of the proposed amendment, a copy of which is provided in Exhibit B attached hereto. Shareholders are encouraged to read the full text of the proposed amendment.

Required Vote

The affirmative vote of a majority of the votes cast on Proposal 2 at the 2017 Annual Meeting is required to approve the EOCPS Plan Amendments. The enclosed WHITE proxy card enables a shareholder to vote “FOR,” “AGAINST” or “ABSTAIN” on this proposal. The proposal will pass, and the EOCPS Plan Amendments will become effective, if the total votes cast “for” Proposal 2 exceed the total number of votes cast “against” Proposal 2. Abstentions and broker non-votes, if any, will not constitute votes cast on Proposal 2 and will accordingly have no effect on the outcome of the vote on this proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU USE THE WHITE PROXY CARD TO VOTE “FOR” APPROVAL OF OUR AMENDED EXECUTIVE OFFICER CASH PROFIT SHARING PLAN.

PROPOSAL 3
RATIFICATION OF SELECTION OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

The Board has selected Grant Thornton LLP (“Grant Thornton”) as the principal independent registered public accounting firm to audit our internal controls over financial reporting and our financial statements for 2017. At the 2017 Annual Meeting, you will be asked to ratify that selection. Grant Thornton has audited our financial statements since 2015. A Grant Thornton representative will be present at the meeting, will be given an opportunity to make a statement at the meeting if he or she desires to do so, and will be available to respond to appropriate questions.

Dismissal of Former Independent Registered Public Accounting Firm

On June 19, 2015, the Board, on the recommendation of its Audit Committee, dismissed PricewaterhouseCoopers LLP (“PwC”) as our independent registered public accounting firm. We provided PwC with a copy of the disclosures that were made regarding its dismissal in a Current Report on Form 8-K (the “Report”) prior to the time the Report was filed with the SEC on June 24, 2015. We requested that PwC furnish a letter addressed to the SEC stating whether or not PwC agrees with the statements made therein. A copy of PwC’s letter dated June 24, 2015, was attached as Exhibit 16.1 to the Report.

The reports of PwC on our consolidated financial statements for the fiscal years ended December 31, 2014 and 2013 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2014 and 2013 and the subsequent interim period through June 19, 2015, there were no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions) with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of PwC, would have caused PwC to make reference thereto in their reports on the consolidated financial statements for such fiscal years. During the fiscal years ended December 31, 2013 and 2014 and any subsequent interim period through June 19, 2015, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), except that our internal control over financial reporting was not effective due to the existence of material weaknesses in our internal control over financial reporting. As disclosed in our Annual Report to Shareholders on Form 10-K for the fiscal year ended December 31, 2013, and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2014, June 30, 2014, and September 30, 2014:

• Our management did not design and maintain effective controls over the valuation of goodwill. Specifically, management did not design a review precise enough to determine the accuracy and support of certain forecasts and assumptions related to the goodwill impairment assessments. This material weakness resulted in errors in our step-one goodwill impairment models, which were not detected by our internal control review process; and

• Our management did not design and maintain effective internal controls related to the valuation of indefinite-lived in-process research and development intangible assets. Specifically, management did not design a process or controls to evaluate impairments at the individual asset level in accordance with accounting principles generally accepted in the United States.

PwC discussed each of these matters with the Audit Committee. We have authorized PwC to fully respond to the inquiries of Grant Thornton, the successor independent registered public accounting firm, concerning these matters.

The aforementioned material weaknesses have been remedied and no material weaknesses in our internal control over financial reporting have been reported for any subsequent reporting periods following September 30, 2014.

{4} Audit fees consist of the aggregate fees billed for professional services rendered for the audit of our annual financial statements included in our Annual Reports on Form 10-K and the review of financial statements included in our Quarterly Reports on Form 10-Q, and services that are normally provided in connection with statutory and regulatory filings or engagements for those years.

{5} Audit-Related fees consist of the aggregate fees billed for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are not reported under the “Audit fees.”

{6} Tax fees consist of the aggregate fees billed for professional services rendered for tax compliance, tax advice, and tax planning. We incurred tax fees in fiscal 2016 primarily for tax compliance in Australia, New Zealand, Hong Kong and Denmark. We incurred tax fees in fiscal 2015 primarily for tax compliance in Australia, New Zealand and France.

The Audit Committee must pre-approve fees to be paid to our principal independent registered public accounting firm before it begins work. The Audit Committee pre-approved all fees and services for Grant Thornton’s work in 2016 and 2015 and PwC’s work in 2015 while PwC was our principal independent registered public accounting firm. The Audit Committee has determined that the fees for services rendered were compatible with maintaining the independence of Grant Thornton and PwC.

PROPOSAL 4
ADVISORY VOTE TO APPROVE NAMED
EXECUTIVE OFFICER COMPENSATION

At each annual meeting, we provide our shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the Securities and Exchange Commission (the “SEC”). This resolution is required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended.

As described in detail below under “Executive Compensation Discussion and Analysis,” we seek to closely align the interests of our Named Executive Officers with the interests of our shareholders. Our compensation programs are designed to reward our Named Executive Officers for the achievement of short-term and long-term strategic and operational goals and the achievement of increased total shareholder value, while at the same time avoiding the encouragement of unnecessary or excessive risk-taking. Please read the “Executive Compensation Discussion and Analysis” and the compensation tables and narrative disclosure that follow for additional details about our executive compensation program, including information about the 2016 compensation of our Named Executive Officers. Our executive compensation program is designed to attract, motivate and retain the Named Executive Officers, who are critical to our success. Please refer to the “Executive Officers” below for qualifications and biographical Information about our Named Executive Officers.

Accordingly, at the 2017 Annual Meeting, we ask that you vote “FOR” the following resolution:

“RESOLVED that the compensation paid to this corporation’s named executive officers, as disclosed in this corporation’s proxy statement for the 2017 annual meeting of stockholders, pursuant to Item 402 of Regulation S-K, including the “Compensation Discussion and Analysis,” compensation tables and narrative discussion within such proxy statement, is hereby approved on a non-binding advisory basis.”

The vote on this resolution is not intended to address any specific element of compensation, the overall compensation of the Named Executive Officers and the compensation philosophy, policies and practices described in this Proxy Statement.

This vote is advisory, which means that it is not binding on us, the Board or its Compensation and Leadership Development Committee. The Board and its Compensation and Leadership Development Committee, however, value the views of our shareholders and will take into account the outcome of the vote when making future compensation decisions for our Named Executive Officers.

Required Vote

The affirmative vote of a majority of the votes cast on Proposal 4 at the 2017 Annual Meeting will approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers. The enclosed WHITE proxy card enables a shareholder to vote “FOR,” “AGAINST” or “ABSTAIN” on this proposal. The proposal will pass, and the compensation of our Named Executive Officers will be approved, if the total votes cast “for” Proposal 4 exceed the total number of votes cast “against” Proposal 4. Abstentions and broker non-votes, if any, will not constitute votes cast on Proposal 4 and will accordingly have no effect on the outcome of the vote on this proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU USE THE WHITE PROXY CARD TO VOTE “FOR” APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL 5
ADVISORY VOTE ON THE FREQUENCY OF ADVISORY VOTES
ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

At the 2017 Annual Meeting, we provide our shareholders with the opportunity to vote, on a non-binding, advisory basis, for their preference as to how frequently we should seek future advisory votes on the compensation of our Named Executive Officers as disclosed in accordance with the compensation disclosure rules of the SEC. This resolution is required pursuant to Section 14A of the Securities Exchange Act of 1934, as amended.

In voting on this Proposal 5, shareholders may indicate whether they would prefer that we conduct future advisory votes on the compensation of our Named Executive Officers every one, two or three years. Shareholders also may, if they wish, abstain from casting a vote on this proposal. The option receiving the most votes (not including “abstain” votes) will be the option chosen by shareholders.

The Board has determined that an annual advisory vote on the compensation of our Named Executive Officers will allow our shareholders to provide timely, direct input on our compensation philosophy, policies and practices as disclosed in our proxy statement each year. The Board believes that an annual vote is therefore consistent with our efforts to engage in an ongoing dialogue with our shareholders on the compensation of our Named Executive Officers and other corporate governance matters. The Company, however, recognizes that shareholders may have different views as to the best approach, and therefore we look forward to hearing from our shareholders as to their preferences on the frequency of advisory votes on the compensation of our Named Executive Officers.

Accordingly, at the 2017 Annual meeting, you will vote on the following resolution:

“RESOLVED that the stockholders recommend, on a non-binding advisory basis, whether a non-binding advisory vote to approve the compensation of this corporation’s named executive officers should occur every one, two or three years.”

This vote is advisory, which means that it is not binding on us, the Board or its Compensation and Leadership Development Committee. The Board may decide that it is in the best interests of our shareholders to hold an advisory vote on the compensation of our Named Executive Officers more or less frequently than the frequency receiving the most votes cast by our shareholders at the 2017 Annual Meeting. The Board and its Compensation and Leadership Development Committee, however, value the views of our shareholders and will take into account the outcome of the vote when considering the frequency of future advisory votes on the compensation of our Named Executive Officers.

Required Vote

The enclosed WHITE proxy card enables a shareholder to vote “1 Year,” “2 Years,” “3 Years” or “ABSTAIN” on this Proposal 5. The choice receiving the largest number of affirmative votes cast, whether or not a majority of the votes has been cast for such choice at the 2017 Annual Meeting, will be the election on Proposal 5 and the frequency of advisory votes on the compensation of our Named Executive Officers chosen by our shareholders. Abstentions and broker non-votes, if any, will not constitute votes cast on Proposal 5 and will accordingly have no effect on the outcome of the vote on this proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU USE THE WHITE PROXY CARD TO VOTE “FOR” THE OPTION OF “ONE YEAR” AS THE PREFERRED FREQUENCY FOR ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL 6
VOTE TO APPROVE A NON-BINDING SHAREHOLDER
PROPOSAL TO DECLASSIFY THE BOARD

Iron Compass Partners, LP has requested that we include the following proposal and its supporting statement in this Proxy Statement. The Board opposes the shareholder proposal for the reasons stated following the proposal and the supporting statement of Iron Compass.

The Proposal

“RESOLVED, that stockholders of Simpson Manufacturing Co., Inc. (the “Company”) request that the Board of Directors of the Company (the “Board”) take all necessary steps (other than any steps that must be taken by stockholders) to eliminate the classification of the Board and to require that directors elected by the stockholders be elected on an annual basis commencing with the first annual meeting of stockholders for the election of directors occurring after the implementation of this proposal, provided that the implementation of this proposal shall not affect the unexpired terms of directors elected prior to such implementation.”

Supporting Statement of Iron Compass

Corporate Governance

We believe the annual election of all directors encourages board accountability to its stockholders and that directors perform better when held accountable for their actions. This view is shared by most stockholders and institutional investors, who believe it to be the standard for corporate governance best practices. The vast majority of companies in the S&P 500 and Russell 1000 indexes elect all board members annually, with only approximately 10.5% and 25%, respectively, of companies retaining classified boards.

Currently, the Board is divided into three classes serving staggered three-year terms. A classified board protects the incumbents and leads to entrenchment, which can limit accountability to stockholders and make the board less responsive to stockholder concerns.

We are committed to improving the corporate governance of the Company for the benefit of all stockholders. Declassification of the Board is a positive step which will allow for more productive stockholder engagement and will help the Company optimize stockholder value.

Accountability and Performance

The Company’s performance has been disappointing over the past several years, due in part to capital allocation decisions that have resulted in deteriorated return on equity and business line extensions that have involved excessive overhead spending and that represent a drag on profitability. After a decade of underperformance, the Company’s strategy must be reevaluated. We believe the Board has failed to take proactive steps to address the Company’s poor performance and misaligned executive compensation practices.

We believe that the Company’s changes regarding capital allocation, corporate governance and executive compensation, which were announced in the latter half of 2016 only after we published a letter that we sent to the Board, represent very modest measures that do not sufficiently address the Company’s greater problems. Furthermore, these changes will be implemented over an unnecessarily long time frame. Perhaps the best example is the newly enacted 15-year outside director term limit, which specifically does not apply to any current directors. In total, we believe that the announcements aim to mute criticism while further preserving the current Board composition.

For a greater voice in the Company’s corporate governance and to increase the accountability of the Board to stockholders, we urge you to vote “FOR” this proposal.

The Board’s Statement in Opposition

The Board unanimously recommends that shareholders vote AGAINST this shareholder proposal because, as described below, the shareholder proposal has already been substantially implemented in a more thoughtful way that provides net benefits to shareholders.

The shareholder proposal requests that the Board “take all necessary steps (other than any steps that must be taken by stockholders) to eliminate the classification of the Board and to require that directors elected by the stockholders be elected on an annual basis commencing with the first annual meeting of stockholders for the election of directors occurring after the implementation of this proposal, provided that the implementation of this proposal shall not affect the unexpired terms of directors elected prior to such implementation.”

The Board has already taken all such necessary steps, including proactively calling a special meeting of shareholders for a vote by shareholders on two proposals: (1) a proposal to amend our Certificate of Incorporation to declassify the Board over a three-year period and provide that director nominees be elected for one-year terms beginning at the 2017 Annual Meeting; and (2) a proposal to amend our Certificate of Incorporation to eliminate the ability to exercise cumulative voting in director elections. The Board approved, adopted and declared advisable these amendments to the Certificate of Incorporation on the condition that these amendments will be implemented only if shareholders approve and adopt both special meeting proposals. Conditioned on the approval and adoption of the two proposals at the March 28, 2017 special meeting, the Board also approved conforming amendments to our Bylaws. If the two proposals are approved and adopted by shareholders, then beginning with the 2017 Annual Meeting, all our directors who are up for re-election, and any new director candidates, will be elected for one-year terms.

As discussed in our special meeting proxy statement, in considering shareholder feedback regarding board declassification, the Board noted that its declassification, if coupled with cumulative voting, exacerbates the potential for disproportionate influence to be exerted by minority shareholders. This is because, all else being equal with respect to an election of directors in which cumulative voting applies, it takes fewer votes to elect a director under a declassified structure than it does under a classified structure. For example, if eight directors were up for election at a shareholder meeting following the declassification of the Board, under cumulative voting, a minority shareholder group holding only approximately 11% of our common stock outstanding could unilaterally seat a director even if holders of the other 89% of our common stock oppose that director’s election. Whereas if the Board remained classified and three directors were up for election at a shareholder meeting, under cumulative voting, a shareholder group owning approximately 25% of our common stock could elect a director candidate regardless of the wishes of holders of the other 75% of our common stock. In light of these concerns, the Board determined that it would not be in shareholders’ best interests, to both declassify the Board and retain the ability to exercise cumulative voting. As a result of this consideration, the Board conditioned implementation of the declassification and elimination of the ability to exercise cumulative voting upon shareholders approving and adopting both such proposals at the special meeting.

In light of the fact that the Board has already taken the necessary steps requested by the shareholder proposal by proactively calling the special meeting to allow shareholders to amend the Certificate of Incorporation to eliminate the classification of the Board and conditionally approving conforming Bylaw amendments, the Board believes that the shareholder proposal has been substantially implemented and is therefore unnecessary.

Moreover, the special meeting proposals, if both approved and adopted, would allow us to effect the Board declassification without further shareholder action and provide for annual election of directors beginning at the 2017 Annual Meeting. In contrast, this non-binding shareholder proposal, if supported by a majority of shareholders, would still require further Board action and a binding shareholder vote to declassify the Board, which would delay annual election of directors beyond the 2017 Annual Meeting. As part of our commitment to strong corporate governance and shareholder democracy, in addition to the steps that have already been taken, the Board has committed to amend our Bylaws to provide proxy access to qualifying shareholders after the March 28, 2017 special meeting.

For the reasons set forth above, the Board unanimously recommends that shareholders vote AGAINST this shareholder proposal.

Required Vote

If properly presented at the 2017 Annual Meeting, Proposal 6 will be decided by the vote of a majority of the votes cast. The enclosed WHITE proxy card enables a shareholder to vote “FOR,” “AGAINST” or “ABSTAIN” on this proposal. The proposal will pass if the total votes cast “for” Proposal 6 exceed the total number of votes cast “against” Proposal 6. Abstentions and broker non-votes, if any, will not constitute votes cast on Proposal 6 and will accordingly have no effect on the outcome of the vote on this proposal.

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU THAT YOU USE THE WHITE PROXY CARD TO VOTE “AGAINST” THE SHAREHOLDER PROPOSAL.

EXECUTIVE COMPENSATION SUMMARY

Board Responsiveness to Shareholders

Following our 2016 annual meeting of shareholders where our advisory vote on executive compensation received 58% shareholder support, the Board undertook a fulsome review of our compensation program with the support of an independent compensation consultant, Mercer LLC (“Mercer”), and conducted extensive shareholder outreach to ensure investor feedback was fully represented in the review.

Our shareholder engagement efforts were led by the Board and senior management. The Chairman of the Board and one or more members of the Compensation and Leadership Development Committee (the “CLDC”) participated in all such discussions with shareholders to ensure a direct line of communication between the Board and our shareholders. As part of our shareholder outreach, we invited dialogue and feedback from holders of a majority of shares of our common stock outstanding. These conversations facilitated direct feedback from shareholders on our compensation program, our governance practices and changes under consideration, all of which was promptly relayed to the full Board and incorporated into our 2016 governance and compensation program reviews.

In direct response to shareholder feedback, the Board approved significant changes to and a major overhaul of our executive compensation practices that are discussed under “Shareholder Feedback and Compensation Program Changes” below.

2016 Performance Highlights

The Company, through its subsidiaries, designs, engineers, and manufactures structural construction products, including connectors, truss plates, anchors, fasteners and other products, and differentiates itself from competitors by designing and marketing end-to-end wood and concrete construction product lines. The Company also provides engineering services in support of some of its products and increasingly offers design and other software that facilitates the specification, selection and use of its products. The Company believes that the Simpson Strong-Tie brand benefits from strong brand name recognition among architects and engineers who frequently request the use of the Company’s products.

The nature of our industry demands that we adhere to a focused strategy to build shareholder long-term value over time. During 2016 our management team continued to execute against the strategic goals set by the Board, which resulted in increases in net sales, income from operations and net income for our shareholders. Key 2016 performance highlights compared to 2015 are set forth below:

• Company-wide net sales increased 8.4% to $860.7 million;

• Gross profit increased 14.9% to $412.5 million; gross margin increased to 48% from 45%;

• Income from operations increased 27.9% to $139.5 million;

• Operating margins increased to 16.2% from 13.7%; and

• Diluted net income per share of our common stock increased 34.8% to $1.86.

Our management’s focused execution and continued commitment to a disciplined capital allocation strategy has delivered strong results for our shareholders in 2016, including the following achievements:

We also outperformed both the S&P 500 and Dow Jones U.S. Building Materials & Fixtures Index in terms of total shareholder returns (“TSR”) delivered to our shareholders in 2016.

After a comprehensive review of our executive compensation practices, directly in response to feedback received from our shareholders, in 2016 the Board approved a wholesale transformation of our executive compensation programs. The Board believes that the changes made to our executive compensation programs closely align our management’s incentive programs with long-term shareholder value and the Company’s strategic goals by:

• Benchmarking all elements of our executive compensation to target median pay for median performance based on our peer group;

• Extending the performance period of our NEOs’ long-term equity awards;

• Revising all outstanding CEO & CFO performance-based equity awards to be fully at-risk and contingent on achievement of performance metrics;

• Reducing the proportion of compensation delivered through our short-term Executive Officer Cash Profit Sharing (“EOCPS”) program;

• Adding full-year performance measurement into the EOCPS program;

• Establishing distinct performance metrics for our NEOs’ short-term EOCPS awards and long-term equity awards; and aligning such metrics with our strategy and priorities.

In addition to the changes made to the compensation program, the Board also approved a number of policy changes in 2016 in order to enhance our compensation governance practices, including:

• Adopting a robust claw-back policy; and

• Adopting a robust anti-hedging and anti-pledging policy.

The table below summarizes the shareholder feedback received on our compensation program, the specific changes the Board has made or plans to make in response, and when each of the changes were or will be implemented.

Implementation of Compensation Program Changes

Due to the number of changes to both our short-term EOCPS program and long-term equity incentive plan (“LTIP”), there will be a period of transition. The following chart illustrates the evolution of our CEO’s key compensation elements and the timing of when the changes that were approved in 2016 will be implemented. As illustrated below, significant changes occurred during 2016 and all changes will be fully implemented by fiscal year 2018, if not earlier.

The CLDC has been very focused on ensuring these changes were implemented as soon as practical. To effect immediate change, the 2016 long-term equity awards granted to our CEO and CFO in the form of performance-based restricted stock units (“PSUs”) were modified in order to subject such awards to the 2017 new performance metrics (revenue growth and ROIC) and the three-year performance measure period illustrated above.

Metric Selection to Align Incentive Programs with Our Strategic Goals

A key element of the Board’s compensation program review focused on the selection of performance metrics that (1) reflect our long-term strategic goals set by the Board and (2) appropriately incentivize our executives to deliver sustainable performance across key areas.

Incentive Component	Performance Metric		Alignment with Our Strategy
CPS	Short-term Operating Profit	• • •	Is a key measure of our profitability Supports long-term value creation Maintains our long-standing culture of promoting sense of ownership among employees to deliver shareholder value
PSUs	3-year Revenue Growth	• •	Aligns with our ongoing focus on growing revenues across key business segments Facilitates decisions that will drive sustainable revenue growth
	3-year ROIC	• •	Reinforces our ongoing focus on maximizing our investment returns Prompts thoughtful capital allocation strategy

Targeting Peer Group Median

The overarching goal of our compensation program is to attract, motivate and retain our employees, including our management team, with a compensation structure that establishes a strong sense of ownership and closely aligns our executives’ interests with those of our shareholders. Given the unique nature of our EOCPS program, this incentive historically provided the opportunity to earn levels of compensation above our peer group median. To offset the magnitude of the potential EOCPS upside, the CEO’s salary was benchmarked to the lower 25th percentile of our peer group. In response to shareholder feedback, and to better align with the market standard, the CLDC in 2017 revised our pay positioning philosophy to target median pay for median performance across all compensation program elements.

This change of practice in targeting total NEO compensation to the median of our peer group requires increasing NEO salaries that used to be below the peer-group median, while reducing EOCPS payouts. See “Comparative Market Information” below for the composition of our updated peer group.

Setting Performance Goals

The CLDC sets performance goals for our NEOs’ EOCPS and long-term equity awards (such as PSUs) prior to granting such awards and remains engaged to monitor and certify the achievement of the goals.

The CLDC believes in the importance of setting challenging, but achievable, performance goals for our NEOs’ EOCPS and long-term equity awards and using such goals to support our median pay for median performance philosophy.

The CLDC engaged in a robust and collaborative performance goal setting process with its independent compensation consultant and our management. In establishing performance goals with respect to our NEOs’ 2017 EOCPS and long-term equity awards, the CLDC considered:

• historical and future projected financial performance for our updated peer group;

• historical and future projected financial performance more broadly in our industry;

• the Company’s historical performance and multi-year forward-looking business plans; and

• the expectations of our shareholders.

In addition, before finalizing the performance goals, the CLDC reviewed projections of realizable pay under our NEOs’ EOCPS and long-term equity awards at various levels of potential achievement of the performance goals to ensure that the actual payouts to our NEOs and our actual performance over the relevant performance periods are closely aligned.

After carefully evaluating the aforementioned factors and incorporating inputs from its independent compensation consultant and our management, the CLDC approved the performance goals for our NEOs’ 2017 EOCPS and long-term equity awards, which are discussed in more detail below under “Executive Compensation Analysis.”

2016 CEO Compensation Summary

As in prior years, our CEO’s 2016 compensation was comprised of three core components: (1) base salary, (2) EOCPS awards, and (3) equity awards. These components are structured to complement each other and establish a balanced and performance-based pay structure. Our CEO’s 2016 compensation mix consisted of the following:

1. Base Salary: $371,316, reflecting a 3% increase from 2015;

2. EOCPS Awards: $1,860,346, reflecting a payout of approximately 110% of the target 2016 EOCPS award ($1,697,000), which payout was determined based on (1) the achievement of our 2016 operating profit goals and (2) the CLDC’s application of discretion to reduce our CEO’s 2016 EOCPS awards by $800,000 in order to improve pay and performance alignment with the peer group; and

3. Equity Awards: $1,781,207 (valued as of the grant date), an increase in grant date value from 2015 to reflect the incorporation of the new performance metrics and longer performance period, with 50% of the equity awards being time-based restricted stock units (“RSUs”) and the other 50% being PSUs.

o The performance metrics of our CEO’s 2016 PSU awards were adjusted following the first year of the performance period to replace the TSR modifier with the new performance metrics (revenue growth and return on invested capital (“ROIC”)) for the remaining two years (see “Changes to Our CEO’s and CFO’s 2016 PSU Awards” below).

o Our CEO’s adjusted 2016 PSU awards are fully at-risk and will vest only on achievement of performance metrics in 2017-2018 performance period. Such awards will be forfeited if threshold performance goals are not met. In contrast, prior to the 2017 adjustment, the target shares under her 2016 PSU awards would only be modified +/-20% before vesting.

Please refer to the “Summary Compensation Table” below for a complete disclosure of our CEO’s 2016 total compensation. Our other NEOs’ 2016 compensation was similarly comprised of the same three core components. See “Executive Compensation Analysis” below.

2017 CEO Compensation Updates

As discussed in “Shareholder Feedback and Compensation Program Changes” above, to better align our NEOs’ short- and long-term incentives with our strategic objectives, the Board, based on the CLDC’s recommendation, has approved certain updates to the compensatory arrangements for our NEOs. The Board believes that, with these updates, median Company performance will result in median compensation for our NEOs and above median performance will result in above median compensation. Because our CEO’s salary has historically been targeted to well below the median of our peer group while her EOCPS awards were targeted above such median, to reflect the transition to targeting each component of her compensation to the median of our peer groups, our CEO’s 2017 compensation reflects an adjustment of these elements.

Our CEO’s 2017 target compensation mix consists of the following:

1. Base Salary: increased to $740,000;

2. EOCPS Awards: target annual EOCPS awards reduced to $740,000 and actual EOCPS awards capped at two times the target awards; and

3. Equity Awards: 50% comprised of PSUs with a three-year performance period and the other 50% comprised of RSUs.

o Our CEO’s 2017 PSU awards are fully at-risk and will vest only on achievement of performance metrics in the 2017-2019 performance period. Such awards will be forfeited if threshold performance goals are not met.

o The CLDC used a formula based on our 2016 net sales to calculate the number of target shares under her 2017 PSU awards.

o The CLDC exercised its discretion to reduce the number of target shares under our CEO’s 2017 PSU awards by 28% in order to improve pay and performance alignment with the peer group.

Our CEO’s 2016 compensation mix and 2017 target compensation mix (as updated) are set forth below:

Similar updates have been introduced to our other NEOs’ 2017 compensation. See “Executive Compensation Analysis” below.

Key Compensation Practices

We are committed to maintaining strong compensation governance practices that support our pay for performance philosophy, mitigate risk, and align interests of our executives and our shareholders. Below is a summary of our key compensation governance practices following the 2017 compensation program changes.

P Target Median Pay for Median Performance: We revised our benchmarking practices to target the 50th percentile of our peer group for median Company performance.

P Pay for Performance: We have created an incentive structure that places a significant portion of our NEOs’ target compensation at risk based on our long-term performance.

P Annual Review of NEO Compensation: The CLDC conducts annual evaluations of our NEOs’ compensation.

P Cap on Annual EOCPS Awards: Following shareholder approval of the proposed plan amendments at the 2017 Annual Meeting, our NEOs’ annual EOCPS awards will be capped at 2 times the target awards.

P Lengthened EOCPS Performance Period: Transitioned from a quarterly measurement period to a mix of annual (50%) and quarterly measurements (50%).

P No overlapping metrics: Performance metrics in the EOCPS plan and LTIP are different.

P Double Trigger change-in-control provisions: Maintain double trigger change-in-control requirements on equity awards.

P Claw-back policy: In 2016, we adopted a robust compensation recovery policy.

P Stock ownership guidelines: Stock ownership guidelines in place for all NEOs.

P Robust Hedging and Pledging Policies: In 2016, we adopted robust hedging and pledging policies.

P Limited perquisites: We do not provide NEOs with material perquisites.

P No guaranteed bonuses: Our NEOs’ EOCPS awards are 100% performance-based and do not guarantee any minimum payments.

P Independent Compensation Consultant: Retained Mercer, an independent compensation consultant, to provide strategic guidance to the CLDC regarding executive and director compensation.

EXECUTIVE COMPENSATION ANALYSIS

Executive Compensation Philosophy

Our overall philosophy is to align the interests of employees and shareholders and provide employees, including our management, incentives to increase long-term shareholder value. To motivate and retain our NEOs and other officers and employees, we aim to compensate them fairly relative to our performance. To achieve these objectives, we created compensation programs that reward achievement of specific performance goals, such as operating profit, revenue growth and return on investment goals and the efficient use of assets. We believe that our compensation programs allow us to attract high-performing employees and help us retain the services of employees whose contributions are instrumental in achieving our performance goals.

Beginning with 2017, the CLDC approved a change to our pay positioning philosophy to position our NEOs’ total target compensation to the median of our peers. The transition to targeting the median of our peer group reflects the feedback of our shareholders and the CLDC believes this pay positioning strategy supports our guiding principal of pay for performance alignment. We regularly review and refine our executive compensation programs to ensure that they continue to reflect practices and policies that are aligned with our pay-for-performance philosophy and the interest of our shareholders.

Compensation-Setting Process

Role of Compensation Committee, Board and Management

The CLDC develops and updates our compensation policies, oversees our compensation programs, sets performance goals relevant to such programs, evaluates our performance in light of such goals, and determines and exercises discretion over executive compensation, including reviewing and approving annual compensation to our NEOs. The CLDC does not delegate its role in determining executive compensation. Our officers do, however, participate in our annual budgeting process, which forms the basis for the CLDC’s determination of the pre-determined performance goals under our compensation programs. The Board reviews and approves the annual budget, and based on that, the CLDC approves both cash EOCPS payouts and equity-based awards to our NEOs.

Role of Compensation Consultants

The CLDC has engaged and expects to continue to engage independent advisers, including compensation consultants, from time to time to assist in carrying out its responsibilities. Since 2014, the CLDC has engaged Mercer as its compensation consultant to provide strategic guidance to the CLDC regarding executive and director compensation. Specific services provided by Mercer to us in 2016 included, but were not limited to, identification of an updated industry peer group and benchmarking analysis, assessment of the appropriateness and competitiveness of our executive compensation program as compared to those of the selected industry peer group, recommendation of changes to our executive compensation programs, especially our NEOs’ compensation mix, and evaluation of our executive and director compensation.

Compensation Program Elements

The Board believes that, to maintain a sense of unity and fairness, the forms of compensation for our NEOs generally should match those of our other employees. Under this principle, our compensation programs for a large portion of our salaried employees, including our NEOs, comprise 3 basic elements:

• Base salaries and contributions to profit sharing trust accounts;

• Cash profit sharing awards, including cash profit sharing awards to our executive officers (“EOCPS awards”); and

• Long-term equity awards.

Each element of our compensation programs possesses characteristics intended to motivate our NEOs and other officers and employees in different ways. We believe that coordinated compensation elements work best to help us to retain their services and to motivate them to achieve results that increase shareholder value. The following is a summary of each of the basic elements of our compensation programs.

Salaries

A NEO’s salary is a guaranteed minimum amount for his or her time invested in performing the functions of the job. Salary alone, however, does not provide performance opportunity for the NEO to earn additional compensation, and at the same time, increase shareholder value over the long term. The Board generally determines our NEOs’ salaries using historical salary levels for their respective positions and adjusts for changes in cost of living and responsibilities. A study conducted by Mercer in 2016 confirmed that our NEOs’ 2016 and historical salaries were below the 25th percentile within our peer group.

In 2017, the Board approved certain updates to our NEOs’ compensatory arrangements. As a part of our NEOs’ 2017 compensation updates and in response to a reduction in our NEOs’ 2017 target and maximum EOCPS awards, the Board approved a salary increase for each of our NEO’s. The table below sets forth, for each of our NEOs, his or her respective 2017 annual salary, as increased from his or her 2016 salary:

	2016 Annual Salary		2017 Annual Salary
Karen Colonias President and Chief Executive Officer	$	371,316	$	740,000

Brian J. Magstadt Chief Financial Officer, Treasurer and Secretary	$	258,157	$	500,000

Ricardo Arevalo Chief Operating Officer, Simpson Strong-Tie Company Inc.	$	222,789	$	460,000

Roger Dankel President of North American Sales, Simpson Strong-Tie Company Inc.	$	222,789	$	460,000

Jeffrey E. Mackenzie Vice President	$	192,903	$	350,000

Salaries paid to each of our NEOs with respect to each of the three years ended December 31, 2016 are set forth in the “Summary Compensation Table” below.

The increased 2017 salary for each of the NEOs is part of a change in the mix of compensation (see “Targeting Peer Group Median” above). On the one hand, there is an increase in such fixed components (salary and, as discussed below, profit sharing trust contribution), and on the other hand, there is a reduction in the 2017 target and maximum EOCPS awards for each of our NEOs under our Executive Officer Cash Profit Sharing Plan (see “Cash Profit Sharing Awards” below). This arrangement, along with the updated 2017 equity awards in the form of restricted stock units to be issued under the Company’s equity incentive plan, is intended to balance both short- and long-term incentives for our NEOs.

Profit Sharing Trust Contributions

The Company and its U.S. subsidiaries maintain a defined contribution profit sharing trust plan for U.S.-based employees, including our NEOs. Some of our non-U.S. subsidiaries maintain similar plans for their employees. An employee is eligible for participation in a given calendar year if he or she is an employee on the first and last days of that year and completes the minimum service requirement during that year. As of December 31, 2016, the minimum service requirement was at least 1,000 hours of service. We currently make contributions to employees’ profit sharing trust accounts in amounts equal to 7% of the employees’ qualifying salaries. We contribute an additional 3% of their qualifying salaries or wages to their profit sharing trust accounts each quarter to comply with the safe-harbor rules that govern the plan. The safe-harbor contribution is not forfeitable and is fully vested when the contribution is made. The plan limits trust contributions to amounts deductible for federal income tax purposes under section 404(a) of Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”). Under this plan, other than the 3% safe-harbor contribution, the Board has exclusive discretion to authorize the trust contributions and change them at any time. Subject to such discretion, we expect the current profit-sharing-trust contribution rate to continue. Our CEO, CFO and Vice President of Human Resources are currently trustees of the profit sharing trust plan. In addition, all our employees, including our NEOs, are entitled to proportionate shares of forfeited contributions from employees who terminate their employment before contributions made for them fully vesting in the profit sharing trust plan. The profit sharing trust plan also includes a 401(k) feature that allows our employees, including our NEOs, to contribute their own pre-tax

earnings in addition to the amounts that we contribute to their accounts. The Board generally views compensation through contributions to employees’ profit sharing trust accounts as serving a similar objective as salaries.

In 2017, the Board has approved certain updates to our NEOs’ compensatory arrangements, which are not expected to materially change our contributions to our NEOs’ profit sharing trust accounts with respect to 2017. The table below sets forth, for each of our NEOs, the contribution that we expect to make to his or her respective profit sharing trust account with respect to 2017, as increased from his or her 2016 profit sharing trust contribution:

	2016 Profit Sharing Trust Contribution		Estimated 2017 Profit Sharing Trust Contribution{1}
Karen Colonias President and Chief Executive Officer	$	27,044	$	27,000

Brian J. Magstadt Chief Financial Officer, Treasurer and Secretary	$	25,748	$	27,000

Ricardo Arevalo Chief Operating Officer, Simpson Strong-Tie Company Inc.	$	22,220	$	27,000

Roger Dankel President of North American Sales, Simpson Strong-Tie Company Inc.	$	22,220	$	27,000

Jeffrey E. Mackenzie Vice President	$	19,240	$	27,000

____________

{1} If we employ the NEO on December 31, 2017, or if he or she retires after reaching the age of 60 during 2017, we will contribute to his or her profit sharing trust account 10% of his or her salary (including the 3% safe-harbor contribution), with a contribution limit of $27,000 for 2017, plus a pro rata share of forfeitures by other participants in our profit sharing trust plan. The estimates in this column assume that no such forfeitures will occur. Of this 10% contribution, the 3% will be paid quarterly in the month following each calendar quarter of 2017 and the rest 7% will be paid in 2018.

Payments made to each of our NEOs’ profit sharing trust account with respect to each of the three years ended December 31, 2016 are set forth in the “Summary Compensation Table” below as part of the “All Other Compensation.”

Executive Officer Cash Profit Sharing (EOCPS) Awards

The Board believes that consistent achievement of short-term performance goals is likely to result in long-term growth and increased shareholder value. Our employees, including our NEOs, are motivated to achieve these short-term performance goals by target awards under our cash profit sharing plans, including our Executive Officer Cash Profit Sharing Plan (the “EOCPS Plan”) for our executive officers and our cash profit sharing plan for other qualified employees. The Board believes that both plans have significantly contributed to the growth of our business.

The EOCPS Plan is maintained partially to help us to meet the requirements of Internal Revenue Code section 162(m) for us to fully deduct the cash awards granted to our NEOs in excess of the $1,000,000 limit as “strategic compensation” thereunder. While the Company generally intends that awards under the EOCPS Plan comply with the requirements of Internal Revenue Code section 162(m), we do not, and cannot, make any representation or warranty that any such award will qualify for favorable tax treatment under Internal Revenue Code or any other provision of federal, state, local or foreign law, and we explicitly reserve the right to issue EOCPS awards not in compliance with Internal Revenue Code section 162(m).

The Board has delegated the oversight of the EOCPS Plan to the CLDC. The CLDC administers such plans, measures the Company or its subsidiaries’ performance against the pre-determined performance goals and approves the amount of the payout that each of our NEOs may receive. The CLDC generally bases the determination of an EOCPS award to a covered officer under the EOCPS Plan on his or her applicable individual percentage of the amount (each, a “Qualified Amount”) by which the net profit, operating income or any other performance goal of the Company or the employee’s relevant branch or subsidiary, including Simpson Strong-Tie Company Inc., the primary operating

subsidiary of the Company, for the applicable period exceed a qualifying level for the Company, branch or subsidiary for that same period, a threshold that must be exceeded before the award may be made to the officer.

2016 Achievements and Awards under the EOCPS Plan

Actual awards under the EOCPS Plan will be made only if the pre-determined performance goals are met. Under the EOCPS Plan, through 2016, we paid quarterly incentive compensation out of the portion of our profits that exceeded a specified qualifying level. The table below sets forth the actual 2016 full-year qualified operating profit, the actual 2016 full-year qualifying level and actual awards that each of our NEOs earned for the full year of 2016 under the EOCPS Plan, in comparison with the target annual operating profit, the target qualified operating profit, the target qualifying level and the target annual payout set by the CLDC at the beginning of 2016.

	Target						Actual
	Qualified Operating Profit		Qualifying Level		Total Payout^{1}		Qualified Operating Profit		Qualifying Level		Total Payout^{2}
Karen Colonias	$	152,406,000	$	75,780,000	$	1,697,000	$	208,362,000	$	73,917,000	$	1,860,346	^{3}

____________

{1} Amounts were expected to be paid for the full year of 2016 if the 2016 actual qualified operating profit is as targeted and the 2016 actual qualifying level is as projected.

{2} The actual payout to the applicable NEO in the table above was the sum of the 2016 quarterly payouts made to his or her under our EOCPS Plan.

{3} To improve pay and performance alignment with the peer group, the CLDC exercised its discretion in the second and third quarters and reduced the amount of the quarterly payout to Karen Colonias by $300,000 and $500,000, respectively.

The basis for calculating the actual 2016 full-year qualified operating profit and the actual 2016 full-year qualifying level used in the table above is as follows:

Quarter	Actual Operating Profit		Actual Qualifying Level		Company Qualifying Income		Home Office Branch Level Pool
First	$	41,519,000	$	16,667,000	$	24,852,000	$	43,000
Second		59,715,000		19,208,000		40,507,000		58,000
Third		65,781,000		19,108,000		46,673,000		65,000
Fourth		41,347,000		18,934,000		22,413,000		39,000
		208,362,000		73,917,000		134,445,000		205,000

The payouts for each of our NEOs for each of the 4 quarters of 2016 were as follows:

CEO/Quarter	CEO Share (%)		Individual Share of Company Qualifying Income ($){1}			Rounding Adjustments ($){2}			($) Payout
Karen Colonias
First	1.9788	%	$	491,759		$	(9	)	$	491,750

{1} The amount is calculated by multiplying the annual company qualifying income with the applicable individual share (%).

{2} The amount represents rounding differences between the amounts used in the actual calculations and the amount calculated using the rounded amounts presented in the tables above.

{3} To improve pay and performance alignment with the peer group, the CLDC exercised its discretion in the second and third quarters of 2016 and reduced the amount of the quarterly payout to Karen Colonias by $300,000 and $500,000, respectively.

{1} The amount is calculated by multiplying the annual company qualifying income with the applicable individual share (%).

{2} The amount is calculated by multiplying the annual home office branch-level pool with the quotient of (i) the applicable individual share (%) divided by (ii) the non-CEO NEO pool as a whole (%).

{3} The amount represents rounding differences between the amounts used in the actual calculations and the amount calculated using the rounded amounts presented in the tables above.

We compute the company qualifying income, if any, as the difference between the actual operating profit and the actual qualifying level. The company qualifying income is the basis for the computation of amounts available to be distributed under both our EOCPS Plan and our Cash Profit Sharing Plan for other qualified employees. The CLDC allocates such amounts among different profit sharing pools and decides such pools’ percentages based on historical information about the profitability of each of our operating units in order to correspond to the effort put forth and the results achieved by different participants to our cash profit sharing program. The CLDC may adjust the pools and their percentages from time to time so that our cash profit sharing programs will continue to create equitable results for all participants, including our NEOs.

A portion of the company qualifying income is shared with our home office employees, including our NEOs but excluding our Chief Executive Officer, in consideration for their contributions to the success of the home office operating unit. These branch-level amounts are added to determine the total amounts paid to our NEOs under our EOCPS Plan.

We then allocated the profit sharing pool(s) among our NEOs based on their participating percentages as approved by the CLDC at the beginning of the year. Each NEO’s participating percentage is decided based on the officer’s level of responsibility and contribution to the success of the Company or the home office operating unit. Unless the composition or responsibilities of our NEOs change, their participating percentages generally do not change substantially from year to year, although the CLDC has discretion to make any changes that it considers appropriate.

For 2016, we divided the profit sharing pool with respect to the company-level qualifying income under our EOCPS Plan, which was 3.9052% of the company qualifying income, into (i) a pool for our Chief Executive Officer (1.9788% of the 2016 company qualifying income), and (ii) a pool for the other 4 NEOs (in total, 1.9264% of the 2016 company qualifying income). Each of our NEOs received his or her share of our 2016 company-level qualifying income.

The amounts of our home office branch-level profit sharing pool for each of the four quarters of 2016 were $43 thousand, $58 thousand, $65 thousand and $39 thousand, respectively. Therefore, each of our NEOs, other than our Chief Executive Officer, received additional home office branch-level payouts for 2016.

CPS awards paid to each of our NEOs with respect to each of the three years ended December 31, 2016 are set forth in the “Summary Compensation Table” below.

2017 EOCPS Plan Amendments

As disclosed under Proposal 2 of this Proxy Statement, the Board, in October 2016, approved amendments to the EOCPS Plan and proposed such amendments to shareholders for approval at the 2017 Annual Meeting. Subject to shareholders’ approval, instead of making quarterly awards, the amended EOCPS Plan allows the CLDC to decide when awards will be made to the covered employees thereunder with respect to a fiscal year; provided that all awards with respect to periods within a fiscal year will be paid by March of the succeeding fiscal year.

Under the current EOCPS Plan, no award in excess of $2,500,000 could be paid to any covered officer with respect to any fiscal year. The proposed amendments did not change this restriction and they added a restriction that, with respect to a particular fiscal year, no award in excess of two times any covered officer’s target annual payout for that year will be paid to such officer under the EOCPS Plan. When assessing whether the $2,500,000 cap and/or the two-times cap under the amended EOCPS Plan have been crossed, all awards made to a covered employee with respect to periods within the same fiscal year will be calculated together.

If shareholders approve the proposed EOCPS Plan Amendments at the 2017 Annual Meeting, the amended EOCPS Plan will apply to awards to be made after the end of 2016. The Company expects to make the first award under the amended EOCPS Plan after the first quarter of 2017. In the event that shareholders do not approve the proposed EOCPS Plan Amendments at the 2017 Annual Meeting, the Company’s current EOCPS Plan, last amended on February 25, 2008, will continue in effect with respect to awards to be made after the end of 2016.

2017 EOCPS Plan Implementation

Based on the flexibility provided by the proposed EOCPS Plan Amendments, the CLDC has determined that, subject to the approval of the proposed EOCPS Plan Amendments by shareholders, the 2017 awards under the EOCPS Plan will be made through five payments, with each of the first four payments to be made quarterly and the last payment to be made at the end of 2017 (or thereafter by March, 2018). For each of the four quarters in 2017, a NEO will receive the awards based on 50% of his or her applicable individual percentage of the respective quarterly Qualified Amount. As for the last payment, the NEO will receive the awards based on 50% of his or her applicable individual percentage of the annual Qualified Amount for 2017.

The effect of this arrangement is to change the payout and timing of our NEOs’ EOCPS awards from four payments per year (all paid quarterly) to five payments per year (four paid quarterly and one paid annually) and reduce the target amount of quarterly awards (each reduced by half) and proportionately increase the target amount of awards made following the end of the year (the target annual award equaling the sum of the four target quarterly awards), with the year-end awards contingent on achieving the Qualified Amount for the entire year.

The CLDC has also determined to use 2017 qualified operating profit of Simpson Strong-Tie Company Inc., the primary operating subsidiary of the Company, as the performance goal for 2017. Such performance goal uses the same methodology that was used in 2016 and prior fiscal years to measure Qualified Amounts under the EOCPS Plan. Qualified operating profit of Simpson Strong-Tie Company Inc. is generally calculated as follows:

Income from operations

Plus: Stock compensation charges

Certain incentive compensation and commissions

Salaried pension contributions

Self-insured workers’ compensation costs

Equals: Qualified operating profit

The CLDC has established the 2017 annual qualifying level at $130,000,000 and the 2017 quarterly qualifying level at $32,500,000 (one fourth of the annual qualifying level), respectively. Our annual company-wide target qualified operating profit, qualifying level and target cash profit sharing pool for 2017 are as follows:

	Company-Wide 2017 Target Annual Pool
Target Qualified Operating Profit	$	228,800,000
Less: Qualifying Level		130,000,000
Target Cash Profit Sharing Pool	$	98,800,000

Assuming that the qualified operating profit exceeds the qualifying level for each quarter of 2017, and therefore annually for the entire year of 2017, each of our NEOs will receive 4 quarterly payouts and 1 annual payout. If the qualified operating profit is less than the qualifying level in one or more quarters of 2017, our NEOs will receive no quarterly payments for such quarters. In addition, if the qualified operating profit is less than the 2017 annual qualifying level, our NEOs will receive no annual payment following the end of 2017 but may still receive one or more quarterly payments during 2017.

The target annual amount and the maximum amount that may be paid out under the amended EOCPS Plan to each of our NEOs for 2017 are as follows:

	2017 Target Annual Payout{1}		2017 Maximum Annual Payout
Karen Colonias	$	740,000	$	1,480,000
Brian J. Magstadt		250,000		500,000
Ricardo Arevalo		230,000		460,000
Roger Dankel		230,000		460,000
Jeffrey E. Mackenzie		175,000		350,000

____________

{1} Amounts expected to be paid for the full year of 2017 if 2017 qualified operating profit of Simpson Strong-Tie Company Inc. is $228,800,000.

Long-Term Equity Awards

Our NEOs’ long-term compensation is entirely equity-based. We currently grant equity awards under the Company’s equity incentive plan, the amended and restated 2011 Incentive Plan (the “2011 Incentive Plan”), to our employees, including our NEOs, only if our profitability goals were met for the prior year. Going forward, we plan to replace such profitability metrics with longer-term metrics in deciding equity grants to our NEOs and other key employees.

2011 Incentive Plan

We awarded restricted stock units under our 2011 Incentive Plan annually, usually in the first quarter, on the day that the CLDC meets to approve the awards that employees earned by meeting our profitability goals for the preceding fiscal year. In 2016, we awarded 442,239 restricted stock units, excluding 10,800 restricted stock units awarded to our outside directors, and no stock options.

Under our 2011 Incentive Plan, the vesting of restricted stock units may accelerate in two situations. First, when an employee ceases employment with us upon his or her retirement depending on whether the employee meets certain age and/or service tenure conditions to the company, death or disability, all of the employee’s unvested restricted stock units vest. Second, all outstanding restricted stock units of an employee vest on a change in our control that involves a substantial change in his or her terms of employment or involuntary termination. In addition, the CLDC may cause awards granted pursuant to our 2011 Incentive Plan, including awards to our NEOs, to vest earlier in certain other situations.

Our NEOs’ 2016 equity awards were made in the following two forms:

1. Time-based restricted stock units (“RSUs”) that vest in equal installments over a period of years; and

2. Performance-based restricted stock units (“PSUs”) that vest based on the achievement of both revenue growth and long-term shareholder returns at the end of a multi-year performance period.

Our NEOs’ 2016 RSU Awards

On granting RSU awards, the CLDC established, and specified in the grant agreement, the vesting schedule for the awards. The number of shares of our common stock subject to RSU awards will generally vest periodically in increments over years.

Because we achieved our operating profit goal for 2015 ($145,145,000), in 2016 the CLDC granted each of our NEOs RSUs as indicated below:

Named Executive Officer		Shares Under 2016 RSUs
Karen Colonias		27,250
Brian J. Magstadt		11,350
Ricardo Arevalo		7,950
Roger Dankel		7,950
Jeffrey E. Mackenzie		1,720

With respect to our NEOs’ 2016 RSU awards, one fourth of the shares of our common stock subject to the awards vested or will vest on the award date and each of the first, second and third anniversaries thereof. See “Accelerated Vesting and Payout” and “Potential Payments on Termination or Change in Control” below for a discussion on early vesting of RSU awards.

Our NEOs’ 2016 PSU Awards

On granting PSU awards, the CLDC established, and specified in the grant agreement, as applicable, the specific performance goals, performance period, vesting period, the maximum number of shares of our common stock granted thereunder and the target number of shares of our common stock to be used as a benchmark. The PSU awards vest only if specific performance goals (as established by the CLDC) are achieved at the end of a performance period (also set by the CLDC). The number of shares of our common stock that eventually vest, however, will depend on the extent to which the performance goals are achieved during the performance period. If threshold performance goals are not met, no shares will vest in favor of the recipient.

With respect to our NEOs’ 2016 PSU awards, depending on a linear function of our company-wide 2015 net sales growth above 2014 net sales, the initial target number of shares would be adjusted between 50% and 200% of the initial target shares. No shares under our NEOs’ PSUs would vest if our 2015 net sales growth was below 4.1%. If our 2015 net sales grew between 4.1% and 8.3%, the adjustment would be prorated. The adjustment was capped at 200% even if our 2015 net sales grew more than 8.3% over 2014.

The threshold, initial target and capped number of shares with respect to each of our NEOs’ 2016 PSUs are as follows:

	Threshold	Initial Target	Capped
	Shares (50%) (at 4.1% Net Sales Growth)	Shares (100%) (at 5.5% Net Sales Growth)	Shares (200%) (at or above 8.3% Net Sales Growth)
Karen Colonias	13,265	27,250	54,500
Brian J. Magstadt	5,675	11,350	22,700
Ricardo Arevalo	3,975	7,950	15,900
Roger Dankel	3,975	7,950	15,900
Jeffrey E. Mackenzie	1,325	2,650	5,300

Because our 2015 net sales growth over 2014 was 5.6%, the CLDC granted PSUs to each of our NEOs with respect to the adjusted target shares as indicated below, which reflected a 2.6% upward adjustment:

Named Executive Officer		Adjusted Target Shares Under 2016 PSUs
Karen Colonias		27,960
Brian J. Magstadt		11,650
Ricardo Arevalo		8,160
Roger Dankel		8,160
Jeffrey E. Mackenzie		2,720

In addition, on granting our NEOs’ 2016 PSUs, the CLDC established that the adjusted target shares would be further modified up or down by up to 20% based our total shareholder return (“TSR”) during a 3-year performance period (from January 1, 2016 to December 31, 2018), which would be measured based on our relative performance in the S&P Small Cap 600 Index. If the Company’s TSR ranks at or above the 85th percentile (with a ranking in the top 90 companies) in the index during the performance period, the number of shares, that would actually vest, is 120% of the adjusted target shares. If the Company’s TSR ranks at or below the bottom 40th percentile (with a ranking below the top 360 companies) in the index during the performance period, the number of shares, that would actually vest, is 80% of the adjusted target shares. If the Company’s TSR falls between the 40th percentile and the 50th percentile (with a ranking from the 301st company to the 360th company) in the index during the performance period, the number of shares, that would actually vest, are prorated between 80% and 100% of the adjusted target shares. If the Company’s TSR falls between the 50th percentile and the 85th percentile (with a ranking from the 91st company to the 300th company) in the index during the performance period, the number of shares, that would actually vest, are prorated between 100% and 120% of the adjusted target shares.

The adjusted target shares, the upward 20% TSR multiplier and the maximum number of shares with respect to each of our NEOs’ 2016 PSUs are as follows:

	Maximum Shares Under 2016 PSUs
	Adjusted Target PSU Shares	20% TSR Multiplier	Maximum PSU Shares
Karen Colonias	27,960	5,592	33,552
Brian J. Magstadt	11,650	2,330	13,980
Ricardo Arevalo	8,160	1,632	9,792
Roger Dankel	8,160	1,632	9,792
Jeffrey E. Mackenzie	2,720	544	3,264

Therefore, the maximum number of shares of our common stock that could potentially vest under each of our NEOs’ 2016 RSUs and 2016 PSUs are as follows:

	Maximum Shares^{1}
	RSU Shares	Maximum PSU Shares	Total
Karen Colonias	27,250	33,552	60,802
Brian J. Magstadt	11,350	13,980	25,330
Roger Dankel	7,950	9,792	17,742
Ricardo Arevalo	7,950	9,792	17,742
Jeffrey E. Mackenzie	1,720	3,264	4,984

____________

{1} The 2011 Incentive Plan, as approved by shareholders at our 2015 annual meeting of shareholders, limits awards of restricted stock units to any one participant in any calendar year to 100,000 shares.

Equity awards granted to each of our NEOs with respect to each of the three years ended December 31, 2016 are set forth in the “Summary Compensation Table” below.

Pursuant to its broad discretion granted under the Company’s equity incentive plan, the CLDC may change the performance goals related to a PSU award to different performance goals as provided under the incentive plan. The CLDC may also provide for fair-value adjustments in case of changing the performance goals.

Changes to Our CEO’s and CFO’s 2016 PSU Awards

At its meeting on October 19, 2016, the Board, at the recommendation of the CLDC, authorized amending the agreements that the Company entered into in 2016 with our CEO and CFO with respect to their 2016 PSU awards (the “PSU Amendments”). These amendments do not affect our CEO’s and CFO’s 2016 RSU awards, which are expected to continue to vest over the three years from the effective date of the award.

Pursuant to the PSU Amendments, our CEO’s and CFO’s 2016 PSU awards would be subject to the original performance goals, which are based on total shareholder return (“TSR”) at the Company (see “Our NEOs’ 2016 PSU Awards” above), only for a one-year period starting on January 1, 2016 and ending on December 31, 2016 (the “First Performance Period”), instead of the original three-year period. As a result, under the 2016 PSU Amendments, the adjusted target shares, calculated based on the achievement of the 2015 revenue goal for the Company, were further adjusted for the accounting fair value of the TSR-based performance goals at the end of 2016 to become the further adjusted target shares of our common stock under the amended 2016 PSU awards for our CEO and CFO. The PSU Amendments also provided that following the end of the First Performance Period, the further adjusted target shares would be subject to new performance goals to be determined by the CLDC and would be measured against such goals for a two-year cliff-vesting period starting on January 1, 2017 and ending on December 31, 2018 (the “Second Performance Period”).

On February 4, 2017, the CLDC set the new performance goals (the “New Performance Goals”) for our CEO’s and CFO’s 2016 PSU awards, which consist of one set of goals based on the Company’s revenue growth (the “Revenue Growth Goals”) and another set of goals based on the Company’s return on invested capital (the “ROIC Goals”). The CLDC also determined that, during the Second Performance Period, half of our CEO’s and CFO’s 2016 PSU awards would be measured against the Revenue Growth Goals and the other half would be measured against the ROIC Goals. As a result, the number of shares of our common stock, which would vest in favor of our CEO and CFO, following the end of 2018, is between 0% and 120% of the further adjusted target shares, depending on the extent to which the New Performance Goals will have been achieved at the end of 2018.

The chart below summarizes the changes made to our CEO’s and CFO’s 2016 PSU awards by PSU Amendments:

The number of the further adjusted target shares of our common stock and the maximum amount of shares of our common stock that could potentially vest under each of our CEO’s and CFO’s amended 2016 PSU awards is as follows:

	Adjusted Target Shares Under Amended 2016 PSU Awards^{1}	Maximum Shares Under Amended 2016 PSU Awards
Karen Colonias	28,990	34,788
Brian J. Magstadt	12,080	14,496

____________

{1} As adjusted for the accounting fair value of the TSR-based performance goals at the end of 2016.

Therefore, the maximum number of shares of our common stock that could potentially vest under each of our CEO’s and CFO’s 2016 RSUs (see “Our NEOs’ 2016 RSU Awards” above) and updated 2016 PSUs are as follows:

	Maximum Shares{1}
	RSU Shares	Maximum PSU Shares	Total
Karen Colonias	27,250	34,788	62,038
Brian J. Magstadt	11,350	14,496	25,846

____________

{1} The 2011 Incentive Plan, as approved by shareholders at our 2015 annual meeting of shares, limits awards of restricted stock units to any one participant in any calendar year to 100,000 shares.

Our NEOs’ 2017 RSU Awards

Because we achieved our operating profit goals for 2016 ($152,406,000), in February 2017, the CLDC granted each of our NEOs RSUs as indicated below:

Named Executive Officer		Shares Under 2017 RSUs
Karen Colonias		24,900
Brian J. Magstadt		10,375
Ricardo Arevalo		7,260
Roger Dankel		7,260
Jeffrey E. Mackenzie		1,720

With respect to our NEOs’ 2017 RSU awards, one fourth of the shares of our common stock subject to the awards vested or will vest on the award date and each of the first, second and third anniversaries thereof. See “Accelerated Vesting and Payout” and “Potential Payments on Termination or Change in Control” below for a discussion on early vesting of RSU awards.

Our NEOs’ 2017 PSU Awards

On February 4, 2017, the CLDC set the new performance goals for our NEOs’ 2017 PSU awards, which would be measured against such goals for a three-year cliff-vesting period starting on January 1, 2017, and ending on

December 31, 2019 (the “Performance Period”). These goals are the same type of new performance goals applicable to our CEO’s and CFO’s amended 2016 PSU awards. The CLDC also determined that, during the Performance Period, half of the 2017 PSU awards to be granted to each of our NEOs would be measured against the Revenue Growth Goals and the other half would be measured against the ROIC Goals (see “Changes to Our NEOs’ 2016 PSU Awards” above). The chart below summarizes the updated performance goals of our NEOs’ 2017 PSU awards.

Consequently, the number of PSU shares that would vest in favor of a NEO under his or her 2017 PSU awards, following the end of the Performance Period, is between 0% and 120% of his or her adjusted target shares, depending on the extent to which the New Performance Goals would have been achieved at the end of 2019. The 2017 PSU awards were granted to our NEOs in early 2017. The number of the adjusted target shares of our common stock and the maximum amount of shares of common stock that could potentially vest under the 2017 PSU awards granted to each of our NEOs is as follows:

	Adjusted Target PSU Shares Under 2017 PSU Awards^{1}	Maximum PSU Shares Under 2017 PSU Awards^{2}
Karen Colonias^{3}	35,874	43,048
Brian J. Magstadt	20,781	24,937
Ricardo Arevalo	14,541	17,449
Roger Dankel	14,541	17,449
Jeffrey E. Mackenzie	4,586	5,503

____________

{1} As adjusted for the accounting fair value of the TSR-based performance goals as of the award date.

{2} No fractional shares will be issued or delivered pursuant to any PSU award, and therefore, any fractional shares may be forfeited or otherwise eliminated as determined by the CLDC.

{3} The target PSU shares for our CEO calculated based on the achievement of our 2016 revenue goal were reduced by 13,784 shares as determined by the CLDC before being adjusted for the award date accounting fair value of the TSR-based performance goals.

Therefore, the maximum number of shares of our common stock that could potentially vest under each of our NEOs’ 2017 RSUs and 2017 PSUs are as follows:

	Maximum Shares{1}
	RSU Shares	Maximum PSU Shares	Total
Karen Colonias	24,900	43,048	67,948
Brian J. Magstadt	10,375	24,937	35,312
Roger Dankel	7,260	17,449	24,709
Ricardo Arevalo	7,260	17,449	24,709
Jeffrey E. Mackenzie	1,720	5,503	7,223

____________

{1} The 2011 Incentive Plan, as approved by shareholders at our 2015 annual meeting of shares, limits awards of restricted stock units to any one participant in any calendar year to 100,000 shares.

Changes to Our NEOs’ Equity Grant Agreements

On February 4, 2017, the CLDC approved changes to the grant agreements related to our NEOs’ 2017 PSU awards and 2017 RSU awards and the amendments related to our CEO’s and CFO’s 2016 PSU awards. The changes mainly focus on two aspects: (a) accelerated vesting and payout, and (b) change in control or asset sale.

Accelerated Vesting and Payout

Under our NEOs’ 2016 and prior grant agreements, our NEOs’ PSU or RSU awards may vest, subject to any applicable performance goals, before the applicable vesting period expires if a recipient retires after reaching age 65, dies or becomes disabled. To increase the compatibility of the awards with the Internal Revenue Code section 409A and avoid potential negative tax implications for the recipient and the Company, the new grant agreements for RSU awards provide that, in case the awards vest ahead of schedule and are determined by the CLDC to be subject to section 409A, they may only be paid out in the enumerated situations as allowed under section 409A. In particular, in case a recipient is a specified employee under Section 409A, the awards cannot be paid out until the date that is six months after the employee’s separation of service, which generally is when the employee completely stops working for the Company and its subsidiaries. Similarly, the new grant agreements and amendments for PSU awards provide that, irrespective of when the PSU awards vest, they may only be paid out following the last day of the applicable vesting period after the performance period has concluded and subject to achievement of the applicable performance goals. Further, the new grant agreements and amendments require that the PSU shares that could eventually become payable in favor of the recipient following the last day of the applicable vesting period after the performance period be prorated based on the early-vesting date and the date when the applicable vesting period is scheduled to expire.

In addition, while still providing for early vesting in case of death or disability, the new grant agreements and amendments require that, for the PSU or RSU awards to vest ahead of schedule, instead of retiring at age 65, a recipient may retire at age 55 and after having worked at the Company or its subsidiaries for 15 years (but for each year that the recipient delays his or her retirement after reaching age 55, he or she may work one year less and still retire).

Change in Control or Asset Sale

The Company’s equity incentive plan currently provides that, on a change in control, if the surviving or resulting entity refuses to continue the PSU or RSU awards and does not substitute similar awards, and if the nature and terms of employment or engagement, including compensation and benefits, of a recipient will change significantly as a result of the change in control, then the awards will vest ahead of schedule. Individual grant agreements may alter this default arrangement.

Our NEOs’ 2016 grant agreements do not change the default rule under the equity incentive plan, but additionally provide that, in the case of an asset sale, the PSU or RSU awards will vest ahead of schedule in certain situations, including where a recipient is not subsequently employed or engaged by the surviving or resulting entity or the successor to the sold business or there is a significant change in the nature and terms of the subsequent employment or engagement of the recipient.

For the ease of administration, our NEOs’ 2017 grant agreements and our CEO’s and CFO’s 2016 grant agreement amendments, use a broader definition, “sale event,” to encompass both change-in-control and asset-sale situations, and therefore override the Company’s equity incentive plan with respect to any change in control of the Company affecting the awards thereunder.

In addition, in order to provide a double-trigger mechanism as recommended by proxy advisors, the new grant agreements and amendments require that for the PSU or RSU awards to vest ahead of schedule on a sale event, a NEO’s employment or engagement with the Company and its subsidiaries (or the acquiring, surviving or resulting entity) will first need to be terminated, either by the officer for good reason or by his or her employer without cause within 2 years from the sale event. In case of early vesting of the PSU awards because of a sale event, the PSU shares thereunder will be subject to the proration described in the “Accelerated Vesting and Payout” section above.

See “Potential Payments on Termination or Change in Control” below for a more detailed discussion on early vesting of our NEOs’ PSU and RSU awards.

Cap on Annual Awards under the Equity Incentive Plan

Under the Company’s equity incentive plan, the maximum aggregate number of the shares underlying any and all RSU and PSU awards issuable or deliverable to such officer in any calendar year cannot exceed 100,000 shares. All of our NEOs’ 2016 and 2017 RSU and PSU awards are subject to this limitation.

Setting the Framework for Equity Awards in 2018 and Beyond

In 2018 or any of the following years, the Company may continue to grant RSUs or PSUs to its NEOs. Based on CLDC’s recommendation, the Board currently plans to split the number of the target shares of our common stock under equity awards to a NEO in 2018 between 20% under RSU awards and 80% under PSU awards. The RSU Awards are expected to vest over the three years from the effective date of the award, with 20% of the awards expected to vest after one year from the effective date of the award, 40% of the awards expected to vest after two years from the effective date of the award and 40% of the awards expected to vest after three years from the effective date of the award. The PSU awards are expected to be subject to future performance goals and be measured against such goals for a three-year cliff-vesting period starting on the first day of the fiscal year during which the awards are made and ending on the last day of the third year.

Comparative Market Information

Designation of New Peer Companies for Setting Executive Compensation

In October, 2016, after considering shareholder feedback, Mercer’s advice, the latest guidelines from proxy advisors and peer companies’ practices, among other considerations, the Board, at the recommendation of the CLDC, authorized updating the 14 peer group companies previously identified with a group of 17 companies for the purposes of setting suitable compensation for our NEOs. The updated peer group companies include companies in the building products or construction material industries having revenues between $400 million and $1.9 billion in 2015, which are approximately 0.4 to 2.5 times the Company’s 2015 revenue. Those 17 companies and the Company, ranked based on their 2015 revenues, are set forth below:

	2015 Revenues (in thousands)	2015 Assets (in thousands)
AAON, Inc.*	359,000	233,000
PGT Innovations, Inc.*	390,000	346,000

Other Compensation Considerations and Practices

Stock Ownership Guidelines for NEOs

In February 2015, to strengthen alignment of interests of our management and shareholders, the CLDC imposed robust stock ownership guidelines for our NEOs. The guideline counts only common stock owned by our NEOs and does not include their stock options or RSUs. Each NEO has until 2020 to comply with his or her guideline. The guideline for stock ownership for each of our NEOs is as follows:

	Stock Ownership Guideline
Karen Colonias	$	3,000,000
Brian J. Magstadt		700,000
Roger Dankel		700,000
Ricardo Arevalo		700,000
Jeffrey E. Mackenzie		150,000

In addition, all of our NEOs are subject to and currently in compliance with our anti-hedging and anti-pledging policy, and are subject to our compensation recovery policy, which policies are described in detail below.

Board-Recommended Frequency of the Advisory Vote on NEO Compensation

The Board has determined that an annual advisory vote by our shareholders on the compensation of our NEOs allows our shareholders to provide timely, direct input on our compensation philosophy, policies and practices as disclosed in our proxy statement each year. The Board continues to believe that such an annual vote is consistent with our continuing efforts to engage in an open dialogue with our shareholders on the compensation of our NEOs and other corporate governance matters and therefore is in the best interests of our shareholders.

Executive Compensation Recovery (“Claw-back”) Policy

The Board believes that it is in the best interests of the Company and shareholders to create and maintain a culture that emphasizes integrity and accountability.

Reinforcing our pay-for-performance compensation philosophy, the Board has adopted a compensation recovery policy in 2016 to permit the recoupment of executive compensation. If we are required to prepare an accounting restatement to correct one or more errors that are material to those financial statements, the Company may recover from (x) any current or former executive officers and (y) any other employees who have been designated by the Board or the CLDC as being subject to this policy (each of such officers or employees, a “Covered Person”), regardless of fault or responsibility, that portion of incentive-based compensation, received by a Covered Person during any Covered Period (defined below) in excess of what would have been paid to a Covered Person during the Covered Period under the accounting restatement.

A Covered Period means (i) the three completed fiscal years preceding the date on which the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under the securities law; and (ii) in case the Company has changed its fiscal year end during the three-year period, the transition period between the new fiscal year that resulted from the change and the prior fiscal year not exceeding nine months. The Board will decide the manner in which the Company seeks and enforces recovery. If, after the Company makes a reasonable attempt to recover, the Board determines that the direct costs of seeking recovery would exceed the recoverable amount, the Company may decide not to seek recovery.

Restrictions on Hedging and Pledging Arrangements for All Employees and Directors

The Board believes that it is inappropriate and undesirable for the Company’s directors, officers or employees to engage in hedging or pledging transactions that lock in the value of holdings in the equity securities of the Company or its affiliates, including our common stock. Such transactions allow the insiders to own the Company’s equity securities without the full risks and rewards of ownership and potentially separate the insiders’ interests from the public shareholders.

The Board has therefore adopted an anti-hedging and anti-pledging policy in 2016. Directors, officers, and employees of the Company or any subsidiary of the Company, as well as their designees, are generally prohibited from: (a) purchasing any financial instruments or engaging in any transactions that are designed to hedge or offset or have the effect of hedging or offsetting any decrease in the market value of our equity securities (such as our common stock), including, without limitation, prepaid variable forward contracts, equity swaps, collars, exchange funds and transactions with economic consequences comparable to the foregoing financial instruments; and (b) further pledging our equity securities as collateral for a loan, purchasing such securities on margin, or holding such securities in a margin account.

Material Risk Considerations of Compensation Policies

We face various types of risk daily, including market risk, credit risk and currency risk, as well as general business risk. Our compensation programs generally look at longer time frames, currently from one quarter to three or four years. Therefore, we do not feel that they expose us to undue risk-taking. To successfully compete in and expand our markets, however, some risk is unavoidable and in some cases desirable and appropriate. See, e.g., risks, uncertainties and factors indicated in the Company’s Annual Report to Shareholders on Form 10-K for the period ended December 31, 2016, under the heading Item 1A — “Risk Factors” and the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

While our compensation programs reward our employees for time spent at work and for the achievement of specific performance goals, we also consider how and to what extent these programs encourage risk-taking. We believe that our cash profit sharing and equity-based awards promote a measured approach to areas of risk that we face as an organization. While the overall objective of our compensation programs is to increase shareholder value, we believe they also encourage sound financial management and the safeguarding of our assets. In addition, we believe our compensation programs promote a sense of unity, fairness and cooperation among all of our employees, not just our management, and afford less opportunity and incentive for individual employees to take undue risk in an attempt to increase their own compensation at the expense of the long-term health of the Company.

Through our short-term cash profit sharing incentive plans, including the EOCPS Plan, our NEOs and other employees are encouraged to maximize our short-term profits, for example, by increasing revenues and reducing operating costs. The qualifying level component the EOCPS Plan is intended to reward prudent stewardship of assets and sound allocation of resources. As disclosed under Proposal 2 of this Proxy Statement, if the proposed EOCPS Plan Amendments are approved by shareholders at the 2017 Annual Meeting, going forward, payouts under the EOCPS Plan will be based 50% on quarterly operating profit and 50% on annual operating profit. Accordingly, each of our NEOs will receive 4 quarterly payouts and 1 annual payout. If the operating profit or other performance goal is less than the qualifying level in one or more quarters of any year, our NEOs will receive no quarterly payments for such quarters. In addition, if the annual qualified operating profit or other performance goal is less than the annual qualifying level in a particular year, our NEOs will receive no annual payment following the end of that year but may still receive one or more quarterly payments during the year. We believe that these changes to the EOCPS Plan reduce the risk that the quarterly time horizon could potentially create opportunities for employees to maximize income in one quarter at the expense of a future quarter.

We currently grant equity-based compensation under our equity incentive plan to our employees, including our NEOs, only if our profitability goals were met for the prior year. Going forward, we plan to replace such profitability metrics with longer-term metrics in deciding equity grants to our NEOs and other key employees, in order to better counterbalance short-term performance goals under the EOCPS Plan and promote a measured risk-taking.

After grant, our equity awards generally vest over a period of years. The value of our equity-based compensation is therefore affected by the long-term market price of our common stock over time. As a result, any attempt to maximize short-term profits at the expense of long-term financial health of the Company would work against our employees’ incentive to maximize their total compensation.

{1} Amounts in this column reflect the grant date fair value of restricted stock units granted to the applicable NEO under the Company’s current equity incentive plan in the year indicated. There were two kinds of RSU awards granted to our NEOs in 2016: time-based restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”). These awards were made on February 1, 2016. See “Executive Compensation Analysis — Long-Term Equity Awards” above. We determined the value of such awards by multiplying the target number of shares of our common stock that may become vested pursuant to the terms of the applicable awards by the fair value of our common stock as of the grant date in accordance with FASB Accounting Standards Codification Topic 718 “Compensation — Stock Compensation.” The fair value of 2016 RSU awards was computed as $31.68 per share, based on the closing price of our common stock reported by the New York Stock Exchange (“NYSE”) at the close of trading on January 29, 2016, discounted for dividends that the RSU awards did not participate in. The fair value of 2016 PSU awards was computed as $32.83 per share, using a Monte Carlo simulation pricing model based on the January 29, 2016 closing price. Our NEOs’ 2015 RSUs awards were granted on February 2, 2015, and were valued at $31.80 per share, based on the closing price of our common stock reported by the NYSE at the close of trading on January 30, 2015, discounted for dividends that the RSU awards did not participate in. Our NEOs’ 2014 RSUs awards were granted on February 3, 2014, and were valued at $30.98 per share, based on the closing price of our common stock reported by the NYSE at the close of trading on January 31, 2014, discounted for dividends that the RSU awards did not participate in. Vesting of all unvested restricted stock unit awards may be accelerated in certain enumerated circumstances, including a change in our control. For a discussion of the valuation assumptions used in determining the grant date fair value of these awards see Note 13 “Stock-Based Compensation” to Consolidated Financial Statements included in our Annual Report to Shareholders on Form 10-K for the period ended December 31, 2016.

{2} Amounts in this column reflect cash incentive compensation earned by the applicable NEO pursuant to the terms of our Executive Officer Cash Profit Sharing Plan with respect to the year indicated (regardless of the year in which such amounts were actually paid). Amounts received by our NEOs under the Executive Officer Cash Profit Sharing Plan were earned in one quarter and paid in the following quarter. As a result, amounts with respect to the fourth quarter of 2014, 2015 and 2016, which are paid as of the first quarter of 2015, 2016 and 2017, respectively, are reflected in the year with respect to which they were earned (that is, 2014, 2015 and 2016, respectively). See “Executive Compensation Analysis — Executive Officer Cash Profit Sharing (EOCPS) Awards” above.

{3} Amounts in this column include our contribution to the applicable NEO’s profit sharing trust account, pursuant to a defined contribution profit sharing trust plan we maintained for U.S.-based employees, including our NEOs, with respect to the year indicated (regardless of the year in which such amounts were actually paid) in an amount equal to the sum of (i) 7% of the applicable NEO’s salary, subject to applicable IRS limits, (ii) a quarterly safe harbor contribution equal to 3% of the applicable NEO’s salary, subject to applicable IRS limits and (iii) a proportionate share of amounts that were forfeited by other employees participating in the profit sharing plan who terminated employment with us before contributions to their accounts fully vested. The contributions earned with respect to the fourth quarter of 2014, 2015 and 2016, which were paid as of the first quarter of 2015, 2016 and 2017, respectively, are reflected in the year with respect to which they were earned (that is, 2014, 2015 and 2016, respectively).

{4} Each of our NEOs’ all other compensation with respect to 2016 includes:

	Profit sharing trust contribution and share of forfeitures ($)	Cost of living adjustment ($)(#)	Charitable gift matching contributions ($)	Total
Karen Colonias	27,044			27,044
Brian J. Magstadt	26,331			26,331
Roger Dankel	22,723	21,000		43,723
Ricardo M. Arevalo	22,723	24,500	1,000	48,223
Jeffrey E. Mackenzie	19,675		1,000	20,675

____________

{#} In connection with Mr. Dankel’s promotion to President of North American Sales of Simpson Strong-Tie Company Inc. and Mr. Arevalo’s promotion to Chief Operating Officer of Simpson Strong-Tie Company Inc., both in July 2014, we agreed to provide each of them with a supplemental cost of living adjustment in the amount of $3,500 per month for a 24-month period. This supplemental cost of living adjustment expired in July 2016.

Grants of Plan-Based Awards

The following table summarizes the cash awards granted to our NEOs during 2016 under our Executive Officer Cash Profit Sharing Plan (the “EOCPS Plan”) and the equity awards under our current equity incentive plan, the amended and restated 2011 incentive plan (the “2011 Incentive Plan”). The Compensation and Leadership Development Committee (the “CLDC”) approved the cash awards because our 2016 quarterly operating profits exceeded the qualifying levels that the CLDC had established at the beginning of 2016. The CLDC approved the restricted stock unit awards because we achieved our 2015 profitability goals that the CLDC had approved at the beginning of 2015.

____________

{1} Amounts in these columns reflect the target and maximum amounts that could become payable under our EOCPS Plan for each of our NEOs. Awards under the EOCPS Plan did not have a threshold value. Actual amounts payable to our Named Executive Officers under the EOCPS Plan were determined based on the level at which our quarterly qualified operating profit

exceeded the qualifying level for that quarter. For more information, see “Executive Compensation Analysis — Executive Officer Cash Profit Sharing (EOCPS) Awards” above.

{2} Amounts reflect the threshold, target and maximum number of performance-based restricted stock units (“PSUs”) of our shares of common stock that could be earned pursuant to the NEO’s 2016 PSU awards. The target number of shares includes an upwards adjustment of 2.6% for each of our NEOs based on the results of the percentage increase of our 2015 net sales over our 2014 net sales. The total number of PSUs earned will be modified by a total shareholder return multiplier up or down by up to 20% based on our relative performance in the S&P Small Cap 600 Index measured from January 1, 2016 through December 31, 2018. For more information, see “Compensation Discussion and Analysis — Long-Term Equity Awards — Our NEOs’ 2016 PSU Awards” above. With respect to Karen Colonias, our Chief Executive Officer, and Brian Magstadt, our Chief Financial Officer, the CLDC authorized amending their 2016 grant agreements, and as a result the number of PSUs that they could earn thereunder, as described above under “Executive Compensation Analysis — Changes to Our CEO’s and CFO’s 2016 PSU Awards.” Pursuant to the amendments, at December 31, 2016, our CEO’s and CFO’s 2016 PSU awards were still subject to the original performance goals, which are based on total stockholder return at the Company. Starting in 2017, our CEO’s and CFO’s 2016 PSU awards are subject to new performance goals, which consist of one set of goals based on the Company’s revenue growth and another set of goals based on the Company’s return on invested capital.

{3} Amounts reflect the actual number of time-based restricted stock units (“RSUs”) of our shares of common stock that were granted, subject to continued time-based vesting. On February 1, 2016, the CLDC determined that our 2015 operating profit goal had been met, resulting in 27,250 RSUs being granted to Ms. Colonias and 11,350, 7,950, 7,950 and 1,720 RSUs being granted to by each of Messrs. Magstadt, Dankel, Arevalo and Mackenzie, respectively. For more information, see “Executive Compensation Analysis — Long-Term Equity Awards — Our NEOs’ 2016 RSU Awards” above.

{4} The amounts in this column reflect the grant date fair value of awards granted to our NEOs in 2016 computed in accordance with FASB Accounting Standards Codification Topic 718. The grant date fair value of 2016 RSUs was computed as $31.68 per share, based on the closing price of our common stock reported by the NYSE at the close of trading on January 29, 2016, discounted for dividends that the RSU awards did not participate in. The grant date fair value of 2016 PSU awards was computed as $32.83 per unit, using a Monte Carlo simulation pricing model. For a discussion of the valuation assumptions used in determining the grant date fair value of these awards, see Note 13 “Stock-Based Compensation” of the Notes to Consolidated Financial Statements included in our Annual Report to Shareholders on Form 10-K for the period ended December 31, 2016.

{1} Calculated by multiplying the number of shares that vested by the market value of such shares on the vesting date.

No Pension Benefits

Except for a small number of employees in our recently acquired Swiss subsidiary, we do not currently have or plan to adopt any defined benefit deferred compensation programs, or supplemental executive retirement plans.

No Non-Qualified Deferred Compensation Plans

We do not currently maintain a non-qualified deferred compensation plan.

Potential Payments on Termination or Change in Control

We generally do not offer any severance payments or pay benefits after termination of employment. As discussed above under “Executive Compensation Analysis — Long-Term Equity Awards,” the vesting of a NEO’s outstanding stock options and restricted stock units, or a portion thereof, may accelerate on, following or in connection with (i) retirement after reaching certain age and/or service tenure conditions, (ii) death, (iii) disability or (iv) certain situations linked to a change in our control or our sale of asset. On, following or in connection with the applicable NEO’s death, disability or retirement after reaching certain age and/or service tenure conditions, or a change in control

or asset sale related situation, in each case assumed to have occurred on December 31, 2016, the potential payments that would be provided to each of our NEOs are as follows:

____________

{1} Calculated based on the $43.75 per share closing price of our common stock reported by the NYSE at the close of trading on December 31, 2016. No material conditions or obligations currently apply to the receipt of payments on early-vesting of equity awards granted to our NEOs.

{2} As of December 31, 2016, Mr. Arevalo was the only NEO eligible for retirement with respect to certain of his equity awards.

{3} Includes potential payments in connection with a sale of assets.

Under our 2011 Incentive Plan, or the applicable grant agreement, the vesting of our NEOs’ restricted stock unit awards may accelerate in four situations: (1) retirement after meeting certain age and/or service tenure conditions, (2) death, (3) disability, and (4) certain situations linked to a change in our control or our sale of asset.

Under our NEOs’ 2016 and prior grant agreements, the applicable NEO’s PSU or RSU awards may vest before the applicable vesting period expires if he or she retires after reaching age 65, dies or becomes disabled. To increase the compatibility of the awards with the Internal Revenue Code section 409A and avoid potential negative tax implications for the recipient and the Company, our CEO’s and CFO’s revised 2016 grant agreements and all our NEOs’ 2017 grant agreements provide that, in case the applicable NEO’s RSU awards vest ahead of schedule and are determined by the CLDC to be subject to section 409A, they may only be paid out in the enumerated situations as allowed under section 409A. In particular, in case the applicable NEO is a specified employee under section 409A, his or her RSU awards cannot be paid out until the date that is six months after the employee’s separation of service, which generally is when the employee completely stops working for the Company and its subsidiaries. Similarly, with respect to our CEO’s and CFO’s revised 2016 PSU grants and all our NEOs’ 2017 PSU grants, irrespective of when the PSU awards vest, they may only be paid out following the last day of the applicable vesting period after the performance-measurement period has concluded.

In addition, while still providing for early vesting in case of death or disability, our CEO’s and CFO’s revised 2016 grant agreements and all our NEOs’ 2017 grant agreements require that, for the PSU or RSU awards to vest ahead of schedule, instead of retiring at age 65, a NEO may retire at age 55, but only after having worked at the Company or its subsidiaries for 15 years. For each year, however, that the recipient delays his or her retirement after reaching age 55, he or she may work one year less and still retire with accelerated vesting.

The 2011 Incentive Plan currently defines “change in control” as any of the following transactions; (i) the consummation of a consolidation or merger of the Company in which the Company is not the surviving corporation; (ii) the consummation of a reverse merger in which the Company is the surviving corporation but the shares of our common stock outstanding immediately preceding such reverse merger are converted by virtue of such reverse merger into other property, whether securities, cash or otherwise; or (iii) the approval by our shareholders of a plan or proposal for the dissolution and liquidation of the Company; provided that a “change in control” shall not be deemed to have occurred by virtue of the consummation of any transaction or series of related transactions immediately following which the record holders of our common stock immediately before such transaction or transactions continue to have substantially the same proportionate ownership in an entity that owns all or substantially all of the assets of the Company immediately thereafter.

The 2011 Incentive Plan currently provides that on a change in control, if the surviving or resulting entity refuses to continue our NEOs’ PSU or RSU awards and does not substitute similar awards, and if the nature and terms of employment or engagement, including compensation and benefits, of the applicable NEO will change significantly as a result of the change in control, then the awards will vest ahead of schedule. The 2011 Incentive Plan, however, allows individual grant agreements to alter this default arrangement.

Our NEOs’ 2016 grant agreements do not change the default rule under the 2011 Incentive Plan but additionally provide that, in the case of an asset sale, the PSU or RSU awards will vest ahead of schedule in certain situations, including where a recipient is not subsequently employed or engaged by the surviving or resulting entity or the successor to the business or there is a significant change in the nature and terms of the subsequent employment or engagement of the recipient.

Our CEO’s and CFO’s revised 2016 grant agreements and all our NEOs’ 2017 grant agreements use a broader definition, “sale event,” to encompass both change in control and asset sale situations, and therefore override the 2011 Incentive Plan with respect to any change in control of the Company affecting the awards thereunder. To provide a double-trigger mechanism as recommended by proxy advisors, under such grant agreements, for our NEOs’ PSU or RSU awards to vest ahead of schedule upon a sale event, the applicable NEO’s employment or engagement with the Company and its subsidiaries (or the acquiring, surviving or resulting entity) will first need to be terminated, either by the officer for good reason or by his or her employer without cause within 2 years from the sale event.

Our CEO’s and CFO’s revised 2016 grant agreements and all our NEOs’ 2017 grant agreements use standard definitions for what constitutes good reason or cause that can typically be found in employment agreements. Under our CEO’s and CFO’s revised 2016 grant agreements and all our NEOs’ 2017 grant agreements, before a NEO may quit for good reason, he or she will first need to provide written notice within 90 days of the underlying incident and inform his or her employer about the reason. In addition, the NEO has up to 30 days to cure following such notice. Similarly, for the Company, a subsidiary thereof, or the acquiring, surviving or resulting entity to terminate a recipient with cause, which results in forfeiture of the NEO’s PSU or RSU awards, the employer will need to provide notice and the NEO has up to 15 days to cure.

In case of early vesting of our CEO’s and CFO’s 2016 PSU awards and our NEOs’ 2017 PSU awards in any one of the four situations, shares thereunder that could eventually vest in favor of the officer will be prorated based on the early-vesting date and the date when the applicable vesting period is scheduled to expire.

In addition, the CLDC may cause awards granted under our 2011 Incentive Plan, including awards granted to our NEOs, to vest earlier in certain other situations.

____________

{1} Reflects the value of restricted stock units granted on April 20, 2016, calculated by multiplying the maximum number of shares that may vest thereunder by the fair value per share of our common stock as of the award date in accordance with FASB Accounting Standards Codification Topic 718 “Compensation — Stock Compensation.” Each outside director’s equity award corresponded to the approximate amount of his or her 2016 annual retainer, and was valued at $38.00 per share, the closing price of our common stock reported by the NYSE at the close of trading on April 19, 2016. For a discussion of the valuation assumptions used in determining the grant date fair value of these awards, see Note 13 “Stock-Based Compensation” to Consolidated Financial Statements included in our Annual Report to Shareholders on Form 10-K for the period ended December 31, 2016.

{2} Represents matching contributions made by us for charitable gifts made by the director. We generally match up to $1,000 for gifts made to qualifying charities.

As of December 31, 2016, our outside directors held the following stock options that had been granted under our 1995 Independent Director Stock Option Plan and restricted stock units that had been awarded under our 2011 Incentive Plan:

Name	Stock Options	Restricted Stock Units
James S. Andrasick	—	1,070
Jennifer A. Chatman	5,000	1,070
Gary M. Cusumano	5,000	1,070
Celeste Volz Ford	—	713
Peter N. Louras, Jr.	—	1,070
Robin G. MacGillivray	5,000	1,070

We pay each of our non-employee directors an annual cash retainer of $65,000. We pay the Chair of the Board an additional annual fee of $56,500 and we pay the Chair of each of the Audit Committee, the Compensation and Leadership Development Committee, the Acquisition and Strategy Committee and the Governance and Nominating Committee an additional annual fee of $10,000. The annual retainer is paid quarterly and the fees for the Chair of the Board and each of its committees are paid at the time of our annual meeting of shareholders each year, and are not prorated. Outside directors will also receive $2,000 for every day, in excess of 12 days during a single calendar year, that a Board and/or committee meeting is held. We also reimburse outside directors for expenses that they incur to attend Board and committee meetings or to participate in educational programs. We pay each outside director $3,000 per day and reimburse his or her expenses when he or she visits our facilities to observe operations.

Stock Ownership Guidelines for Outside Directors

In February 2015, the Compensation and Leadership Development Committee created stock ownership guidelines for each of our directors, who is not also an officer or employee. The guideline counts only our common stock owned by them and does not include their stock options or restricted stock units. Each of such directors has until 2020 to comply with this guideline. The guideline for the minimum value for stock ownership of the Company for each of such directors is computed as 3 times their annual cash retainer, which is currently $195,000. All of our directors are currently in compliance with our stock ownership guidelines. In addition, all of our directors are subject to and currently in compliance with our anti-hedging and anti-pledging policy that was adopted by the Board in 2016.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Transactions with Related Persons

Since January 1, 2016, other than the compensation arrangements discussed under “Executive Compensation” and “Director Compensation” above, we did not have any transactions to which we have been a participant, in which the amount involved in the transaction exceeds or will exceed $120,000 and in which any of our directors, executive officers or holders of more than 5% of our common stock, or any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law of, or person (other than a tenant or employee) sharing the household with, any of these individuals, had or will have a direct or indirect material interest.

In 2016, the Company paid Tacit Knowledge, a consultant on a software implementation project, $1.9 million for its services. The project started in 2015 and is expected to be continuing in 2017. Chris Andrasick, the Company’s Director James S. Andrasick’s son, co-founded Tacit Knowledge in 2002. Tacit Knowledge was sold to Newgistics, Inc. (“Newgistics”) in 2013. Chris Andrasick was hired by Newgistics in 2013, as its Chief Strategy and Innovation Officer for Digital Commerce, but has had no financial interest in Tacit Knowledge since the 2013 acquisition, other than in his role as an officer of Newgistics. The payments that the Company made to Tacit Knowledge in 2016 were less than 0.5% of Newgistics’ consolidated gross revenues for the fiscal year ended December 31, 2016. Our director Andrasick has had no financial interest in Tacit Knowledge.

In 2016, Karen Colonias, the Company’s President, Chief Executive Officer and Director, was named as a director of Reliance Steel & Aluminum Co. (“Reliance”). Reliance, through its subsidiaries, has been a provider of steel processing and handling services for the Company for several years. In 2016, the Company paid Reliance $0.7 million for its services. The relationship between the Company and Reliance is expected to be continuing in 2017. Pursuant to instructions to Item 404(a) of Regulation S-K, we do not deem Ms. Colonias to have a direct or indirect material interest in our relationship with Reliance solely because of her position as a director of Reliance.

Review, Approval or Ratification of Transactions with Related Persons

The entire Board is responsible for review, approval, and ratification of transactions between the Company or its subsidiaries and related persons. We adopted a written related-parties policy and procedures that apply to any transaction or series of transactions in which we or any of our subsidiaries is a participant. In addition to “related persons” defined in Item 404 of Regulation S-K, our related-parties policy and procedures also cover (1) each company in which any of the related persons has a substantial interest, and (2) any employer of any of our Directors. In accordance with the adopted policy and procedures, transactions involving related persons are generally reviewed by our accounting staff, which determines whether a related person could have a material interest in such a transaction, and then each transaction identified by our accounting staff is submitted to the Board for review. The Board will determine whether or not a particular relationship serves the best interest of the Company and its shareholders and whether the relationship should be continued or eliminated. Our related-parties policy and procedures have been and are followed with respect to all transactions identified in the “Transactions with Related Persons” above.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act, requires our directors and officers and persons who own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership of our common stock with the SEC. SEC regulations require such persons to furnish us with copies of all section 16(a) reports that they file. Based solely on our review of the copies of such reports that we received and written representations from the executive officers and directors, we believe that in 2016 our directors and officers and 10% shareholders met all of the section 16(a) filing requirements regarding our common stock with the following exceptions:

Sharon H. Simpson		Sold shares in three transactions in April of 2016 and was 2 days late filing her current report on Form 4.
Simpson PSB Fund		Sold shares in three transactions in April of 2016 and was 2 days late filing its current report on Form 4.

HOUSEHOLDING OF PROXY MATERIALS

SEC rules permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy materials with respect to two or more shareholders sharing the same address by delivering a single copy of the proxy materials addressed to those shareholders. This process, which is commonly referred to as “householding,” provides cost savings for companies. Some brokers household proxy materials, delivering a single proxy statement and annual report to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement in the future, or if you and other shareholders sharing your address are receiving multiple copies of the proxy materials and you would like to receive only a single copy of such materials in the future, please notify your broker. You may also call (800) 542-1061 or write to: Householding Department, Broadridge, 51 Mercedes Way, Edgewood, New York 11717, and include your name, the name of your broker or other nominee, and your account number(s). If you share an address with another shareholder and have received only one set of this year’s proxy materials and you wish to receive a separate copy, please notify us in writing to our Secretary at Simpson Manufacturing Co., Inc., 5956 W. Las Positas Blvd., Pleasanton, California, 94588 and we will deliver a separate copy to you promptly.

The Committee shall determine in writing the Performance Goal, the qualifying level and the Covered Employees’ Measurement Percentages with respect to a Period, no later than the latest time permitted by the Code for that Period. Each Measurement Percentage will be based on the respective Covered Employee’s then-current job function.

For each fiscal year, the Committee shall set a targeted level for the entire company, or the employee’s relevant branch or subsidiary, respectively. A Covered Employee’s individual percentage of the amount by which the annual targeted level exceeds that year’s qualifying level is such officer’s targeted annual compensation under this Plan (the “Targeted Annual Payout”).
