<p style="margin-top:12pt;margin-bottom:0pt;margin-left:8.35%;text-indent:7.59%;font-size:14pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As you know, March 2020 marked a personal anniversary: I have now served as both the Executive Chairman and as a Board Member of Patterson-UTI Energy, Inc. and its predecessor, UTI Energy Corp., for more than twenty-five years.</p>
<p style="margin-top:12pt;margin-bottom:0pt;margin-left:8.35%;text-indent:7.59%;font-size:14pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">My &#8220;silver&#8221; anniversary with the Company marks an appropriate time for me to &#8220;step down&#8221; from both the Board of Directors, and with that, to step down as Executive Chairman. I do plan to serve the balance of my term (i.e., until the next Annual Meeting) as a Director and as the Company&#8217;s Executive Chairman but I will not &#8220;stand&#8221; for re-election as a Director at the Annual Meeting.</p>
<p style="margin-top:12pt;margin-bottom:0pt;margin-left:8.35%;text-indent:7.59%;font-size:14pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">As we both know, over the past five years Andy Hendricks has grown and is today one of the finest Chief Executive Officers in the Oilfield Services industry. His performance and leadership have enabled me to gradually step back and allow him more and more latitude. I have no doubt that Andy, along with the super talented management team in place, will continue to manage the Company in a superb manner that will enable Patterson-UTI to remain a leader in this industry. I&#8217;m proud of what we have accomplished, and even more excited about what they will achieve!</p>
<p style="margin-top:12pt;margin-bottom:0pt;margin-left:8.35%;text-indent:7.59%;font-size:14pt;font-family:Times New Roman;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">Because Patterson has been such an important part of my life for 25 years, I&#8217;m not ready to say a final goodbye to the talented Board members, executives and everyone at Patterson with whom I have worked. So, I am delighted that the Board has found a way for me to stay involved on a part-time basis.</p>

My decision is truly personal. It has nothing to do with the recent Coronavirus pandemic or current circumstances in energy; Patterson-UTI has always emerged from downturns a stronger company and I am confident this will be the case again. For me, it is simply time to let others take charge.</font></p>

Siegel, has advised the Company of his intention to retire after more than 25 years of continuous service to Patterson-UTI Energy and its predecessor companies.&nbsp;&nbsp;Mr. Siegel has decided not to stand for re-election to the Board of Directors and to retire as Executive Chairman, at the time of the Company&#8217;s annual shareholder meeting, when it is anticipated that Mr. Curtis Huff will be appointed Non-Executive Chairman.&nbsp;&nbsp;Mr. Huff has been a member of the Board of Directors of Patterson-UTI and one of its predecessor companies for 23 years and currently serves as the Company&#8217;s Lead Independent Director.</font></p>

Under his visionary leadership, a small, regional drilling company, through both mergers and organic growth, has become a leading oilfield services company and a primary player in the U.S. unconventional shale revolution.&nbsp;&nbsp;Given Mark&#8217;s long history with Patterson-UTI and his deep experience in our industry, I am pleased that Mark has agreed to <font style="color:#000000;">provide transition support services and advice on strategic and other matters to the Company after he steps down as Executive Chairman.</font></p>
