Dawson Geophysical Company, previously known as TGC Industries, Inc., today announced the completion of its previously announced strategic business combination effective February 11, 2015. Trading in the combined company’s common stock will open on NASDAQ on February 12, 2015 under the symbol “DWSN” on a post-split basis (CUSIP No. 239360100).

Under the terms of the transaction, which was structured as a stock-for-stock merger and intended to qualify as a tax-free reorganization, Dawson Operating Company, previously known as Dawson Geophysical Company (“Legacy Dawson”), merged with a wholly owned subsidiary of Dawson Geophysical Company (the “Combined Company”), previously known as TGC Industries, Inc. (“Legacy TGC”) and continued as the surviving entity and a wholly owned subsidiary of the Combined Company. As consideration for the transaction, all outstanding shares of Legacy Dawson’s common stock, par value $0.33 1/3 per share, were converted into the right to receive 1.760 shares of Legacy TGC’s common stock, par value $0.01 per share, after giving effect to a 1-for-3 reverse stock split of Legacy TGC’s common stock. Immediately prior to the effective time of the transaction, Legacy Dawson changed its name to “Dawson Operating Company” and Legacy TGC changed its name to “Dawson Geophysical Company”.

After the close of regular NASDAQ trading hours on February 11, 2015, and immediately prior to the effective time of the transaction, Legacy TGC effected a 1-for-3 reverse stock split of its outstanding common stock. As a result of the reverse stock split, every three (3) shares of Legacy TGC’s common stock outstanding immediately prior to the transaction were combined and reclassified into one (1) share of Legacy TGC common stock. No fractional shares will be issued in connection with the reverse stock split. Instead, each fractional share to be issued to a Legacy TGC shareholder will be rounded up to the nearest whole share.

Legacy TGC retained its transfer agent, American Stock Transfer & Trust Company, LLC (“AST”), to act as its exchange agent for the reverse stock split.  AST will provide shareholders of record of Legacy TGC immediately prior to the merger, which was the effective time of the reverse stock split, with a letter of transmittal providing instructions for the exchange of their certificates and book-entry shares representing pre-reverse stock split shares for certificates and book-entry shares representing post-reverse stock split shares in the name of the Combined Company. Shareholders owning shares through a broker or other nominee will have their positions automatically adjusted to reflect the reverse stock split, subject to brokers’ particular processes, and will not be required to take any action in connection with the reverse stock split and the name change of the Combined Company.

The consummation of the reverse stock split reduced the number of Legacy TGC’s outstanding shares of common stock on a pre-transaction basis from approximately 22.0 million shares to 7.3 million shares. Immediately after the issuance of shares to Legacy Dawson’s shareholders in connection with the transaction, the Combined Company had approximately 21.6 million shares of common stock outstanding, with Legacy Dawson shareholders owning approximately 66% of the Combined Company and Legacy TGC shareholders owning approximately 34% of the Combined Company. The Combined Company is authorized to issue an aggregate of 35.0 million shares of common stock, including the shares mentioned above.  AST is also acting as the exchange agent in connection with the transaction and will send to the former registered holders of Legacy Dawson’s common stock a letter of transmittal containing instructions on how to exchange Legacy Dawson stock certificates and book-entry shares for certificates and book-entry shares of the Combined Company.

The Combined Company is operating under the leadership of Stephen Jumper, who serves as the Combined Company’s Chairman, President and Chief Executive Officer, and Wayne Whitener, who serves as an officer of the Combined Company and as Vice Chairman of the Combined Company’s board of directors. In addition to Messrs. Jumper and Whitener, the Combined Company’s board of directors includes four members of the Legacy Dawson board—Craig Cooper, Gary Hoover, Ted North and Mark Vander Ploeg—and two members of the Legacy TGC board —William Barrett and Dr. Allen McInnes. In addition to Messrs. Jumper and Whitener, the board of directors of the Combined Company appointed James K. Brata, Christina W. Hagan, James W. Thomas, C. Ray Tobias and Daniel G. Winn as officers of the Combined Company.

Raymond James & Associates, Inc. served as financial advisor to Legacy Dawson while Stephens Inc. served as financial advisor to Legacy TGC. Baker Botts L.L.P. served as legal counsel to Legacy Dawson while Haynes and Boone, LLP served as legal counsel to Legacy TGC.
