Item 7.01. Regulation FD Disclosure.

Stuart M. Brightman, Chief Executive Officer and a director of TETRA Technologies, Inc. (“TETRA” or the “Company”), has adopted a pre-arranged trading plan (the “Plan”) to sell shares of the Company’s common stock in connection with the exercise of nonqualified stock options previously granted to Mr. Brightman. The Plan was designed to comply with Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, and the Company’s policies regarding stock transactions. Under Rule 10b5-1, directors, officers and other affiliates of an issuer who are not in possession of material non-public information may adopt a pre-arranged plan or contract for the sale of the issuer’s securities under specified conditions and at specified times.

The Plan has been adopted by Mr. Brightman to facilitate his exercise of 100,000 nonqualified stock options that will expire on February 12, 2019. Under the terms of the Plan, the nonqualified stock options will be exercised and the underlying shares will be sold, in one or more transactions, on the open market at prevailing market prices, subject to minimum price thresholds, beginning on June 21, 2018. The Plan is scheduled to terminate on February 12, 2019 (or sooner under certain circumstances including the sale of all shares under the Plan).

The Company does not undertake to report other Rule 10b5-1 plans that may be adopted by officers or directors of the Company in the future, or to report any modifications or termination of any publicly announced plan, except to the extent required by law.Additional officers of the Company may from time to time also adopt Rule 10b5-1 Plans.
