Introductory Note:

On April 20, 2017, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 12, 2016, by and among Seventy Seven Energy Inc., a Delaware corporation (“SSE”), Patterson-UTI Energy, Inc., a Delaware corporation (“Patterson-UTI”), and Pyramid Merger Sub, Inc. (“Merger Sub”), Patterson-UTI completed its Merger with SSE, which was accomplished through the merger of Merger Sub with and into SSE, with SSE surviving the Merger as a wholly-owned subsidiary of Patterson-UTI.

At the effective time of the Merger (the “Effective Time”) each issued and outstanding share of SSE common stock, par value $0.01 per share, other than shares owned by SSE and its wholly owned subsidiaries, shares owned by Patterson-UTI or Merger Sub and shares for which appraisal rights held by SSE stockholders have been perfected in compliance with Section 262 of the General Corporation Law of the State of Delaware, was converted into the right to receive 1.7851 shares (the “Exchange Ratio”) of newly issued Patterson-UTI common stock, par value $0.01 per share, rounded down to the nearest whole share. Instead of issuing fractional shares, each SSE stockholder who otherwise would have been entitled to receive a fraction of a share of Patterson-UTI common stock will receive cash (without interest) in lieu thereof, upon surrender of his or her shares of SSE common stock. The exchange agent will aggregate and sell all fractional shares issuable as part of the merger consideration at the prevailing price on the Nasdaq Global Select Market. An SSE stockholder who would otherwise have received a fraction of a share of Patterson-UTI common stock will receive an amount of cash generated from such sales attributable to the stockholder’s proportionate interest in the net proceeds of such sales, less expenses and without interest. The newly issued shares of Patterson-UTI common stock and the cash paid in lieu of fractional shares are collectively referred to as the “Merger Consideration.”

Shares of Patterson-UTI common stock outstanding before the Effective Time remain outstanding and have not been exchanged, converted or otherwise changed in the Merger. Based on the number of shares of SSE common stock issued and outstanding or deemed outstanding immediately prior to the Effective Time, a total of 47,538,488 shares of Patterson-UTI common stock were issued to the former holders of SSE common stock pursuant to the Merger Agreement.

Immediately prior to the Effective Time, each SSE restricted stock unit award granted prior to December 12, 2016 that was outstanding as of immediately prior to the Effective Time (the “Incentive Awards”) immediately vested, any forfeiture restrictions applicable to such Incentive Awards immediately lapsed, the Incentive Awards were deemed settled, and each share of SSE common stock subject to such Incentive Awards was treated as a share of SSE common stock. At the Effective Time, each such share of SSE common stock that was distributed in settlement of the Incentive Awards entitled the holder thereof to receive the Merger Consideration. In addition, at the Effective Time, each SSE restricted stock unit award granted on or following December 12, 2016 was assumed by Patterson-UTI and converted into a restricted stock unit award, with the same terms and conditions as in effect immediately prior to the Effective Time, covering a number of shares of Patterson-UTI common stock equal to (i) the number of shares of SSE common stock subject to the award immediately prior to the Effective Time, multiplied by (ii) the Exchange Ratio, rounded to the nearest whole share. None of SSE’s directors or executive officers held SSE restricted stock unit awards granted on or following December 12, 2016.

The foregoing description of the Merger Agreement and the Merger is only a summary, does not purport to be complete, and is subject to, and qualified in its entirety by reference to, the Merger Agreement, which was filed as Exhibit 2.1 to SSE’s Current Report on Form 8-K filed with the Securities Exchange Commission (the “SEC”) on December 13, 2016 and is incorporated herein by reference.
