Stock Ownership Guidelines

The Board of Directors (the “Board”) of Tetra Tech, Inc. (the “Company”) has adopted stock ownership guidelines for executive officers and directors, which has been amended and restated as of November 7, 2016 (the “Effective Date”).  The Board may further update these guidelines from time to time.  The Board believes that share ownership aligns the interests of its executive officers and directors with the interests of shareholders, promotes sound corporate governance, and demonstrates a commitment to the Company.

Guidelines for Executive Officers

All executive officers are required to own shares of Company stock having a total value equal to the lesser of a specified multiple of base salary or a minimum number of shares, as set forth in the following table:

Position Multiple of Base Salary Minimum Shares
Chief Executive Officer 6 170,000
Executive Vice President 3 40,000
Senior Vice President 2 20,000

Until an executive officer’s stock ownership requirement is met, the executive officer must retain at least 75% of Gain Shares resulting from the exercise of a stock option or vesting of a restricted stock award.  With respect to stock options, “Gain Shares” means the total number of shares of the Company stock that are being exercised less the number of shares, if any, used in the case of a cashless exercise to pay for the exercise price.  With respect to a restricted stock award, “Gain Shares” means the total number of shares of Company stock subject to any such equity award that vest.  Gain Shares shall in no event include shares of Company stock subject to any form of equity award that are used to satisfy tax withholding obligations for federal and state income and employment taxes on any gain attributable such an award.

Executive officers on the Effective Date will have five years from the Effective Date e to attain the required level of stock ownership applicable to their positions. Executive officers appointed after the Effective Date will have five years from the date of appointment to attain the required level of stock ownership.  Executive officers who are subsequently promoted to either the CEO or an Executive Vice President position will have five years from the date of promotion to acquire any additional shares needed to attain the required level of stock ownership.

Guidelines for Directors

Each directors are required to own shares of Company stock having a total value equal to the lesser of at least three times the director’s annual base cash retainer or 6,100 shares.

Until a director’s stock ownership requirement is met, the director must retain at least 75% of Gain Shares resulting from the exercise of a stock option.  “Gain Shares” shall have the same meaning as described above except that Gain Shares shall exclude shares of Company stock that would have been used to satisfy minimum tax withholding obligations had the director been employed by the Company as a common law employee.

Directors on the Effective Date will have five years from the Effective Date to attain the required level of stock ownership.  Directors elected after the Effective Date will have five years from the date of election to the Board to attain the required level of stock ownership.

  • Shares owned separately by the executive officer or director or owned either jointly with, or separately by, his or her immediate family members residing in the same household;
