<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">MIDLAND, Texas, November&nbsp;16, 2021/PR Newswire/Dawson Geophysical
Company (NASDAQ: DWSN) (&ldquo;Dawson&rdquo; or the &ldquo;Company&rdquo;) today released the following letter to shareholders concerning
the pending tender offer by Wilks Brothers, LLC issued by Stephen C. Jumper, President and Chief Executive Officer on behalf of the Dawson
Board of Directors.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">November&nbsp;16, 2021</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Fellow Dawson Shareholders:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">As
previously disclosed, the Company announced a transaction with Wilks Brothers, LLC (&ldquo;Wilks&rdquo;) on October&nbsp;25, 2021. The
transaction involves a tender offer by a Wilks subsidiary to purchase outstanding Dawson common shares at $2.34 per share and a follow-on
merger. The tender offer commenced on November&nbsp;1, 2021 and is open until November&nbsp;30, 2021 (subject to extensions under certain
circumstances). The transaction is well described and documented in the Schedule 14D-9 and Schedule TO-T filed with the SEC by Dawson
Geophysical Company (&ldquo;Dawson&rdquo; or the &ldquo;Company&rdquo;) and WB Acquisitions Inc., respectively, on November&nbsp;1, 2021,
which can be obtained at the website maintained by the SEC at <U>www.sec.gov</U></FONT>.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Beginning in September&nbsp;of 2019, Dawson and its Board of Directors,
with the assistance of financial advisor Moelis&nbsp;&amp; Company LLC, commenced an on-going review and analysis of the Company&rsquo;s
potential strategic alternatives, transactions or actions in an effort to preserve and enhance shareholder value. From July&nbsp;9, 2018,
to September&nbsp;2, 2019, the Company&rsquo;s share price declined from $8.09 to $2.11. The PHLX Oil Service Index also declined materially
over the same time frame as the energy sector fell out of favor in the public equity markets; however, the decline in the Dawson share
price exceeded the decline in the index. In response to shifting public investor sentiment, publicly traded North American based Exploration
and Production (E&amp;P) companies began to alter their capital spending plans with a focus on generating free cash flow and returning
capital to shareholders. This change in capital allocation priorities by E&amp;P companies, which accelerated further in 2020 and 2021,
has resulted in less demand for North American onshore seismic data acquisition services, thus significantly affecting Dawson&rsquo;s
revenue stream.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In parallel to evaluating potential strategic alternatives, we began
a process to resize the Company as our model shifted to fewer, larger channel count crews, and to reduce capital expenditures to protect
the balance sheet and cash balances. This was done with the goal of maintaining our ability to compete and execute large scale projects
as they materialized. Since early 2020, we have undergone further efforts to right-size, reduce salaries for most employees, including
all of management, and reduce fixed costs in an effort to protect the balance sheet and cash balances.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0"><FONT STYLE="font-family: Times New Roman, Times, Serif; font-size: 10pt">During
this time frame, we remained optimistic about a recovery in the onshore U.S. seismic market and experienced intermittent quarters of success
with reasonable utilization of our equipment. When projects have been available, the Company has executed very efficiently and continues
to do so. Despite our optimism, improved oil and gas prices and a slight uptick in bid activity in the middle of this year, sufficient
revenue producing opportunities have yet to materialize in any meaningful way. Recent earnings reports by the E&amp;P companies continue
to project flat production levels in 2022, only slight increases in spending and continued focus on </FONT><FONT STYLE="font-family: Times New Roman, Times, Serif">returning
capital to shareholders</FONT>, debt reduction and capital discipline. Our conversations with our customers and ongoing marketing efforts
confirm this sentiment.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">In 2021, our cash burn has accelerated despite our efforts to right-size
and curtail expenses. Our accounts receivable balance became depleted as we collected cash. This action resulted in a negative net working
capital (defined as current assets less current liabilities excluding the impact of cash, restricted cash and short-term investments and
current maturities of notes payable and finance leases and operating lease liabilities) position at September&nbsp;30, 2021, and opportunities
to further reduce costs or cut capital expenditures are minimal. Activity levels in 2022 are expected to be well below levels we anticipated
a few quarters ago. While other sub-sectors in the oil&nbsp;&amp; gas and oilfield services sectors are beginning to experience modest
activity level improvements, those improvements are focused around completion and production related services opportunities, not exploration
or seismic data related exploration-focused activities which impact Dawson. Even so, overall activity levels will likely be well below
2019 levels across the vast majority of the sub-sectors mentioned.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">We expect that our activity levels from February&nbsp;to mid-fall of
2022 will be similar to levels experienced in the second and third quarters of 2021, and then expected to only slightly improve in late
2022. Visibility beyond 2022 is unclear, but given the expected state of capital spending on oilfield services, we do not anticipate meaningful
increases. Therefore, with reduced activity levels, we expect our cash balances to continue to decline during this period. Additionally,
our ability to fund future maintenance capital requirements will be challenging and further impact cash flow. As of November&nbsp;12,
2021, our cash, restricted cash and short term investments were approximately $36,500,000, representing an expected further decline from
our previously announced September&nbsp;30, 2021 balance while our accounts receivable balance increased related to the previously disclosed
recent redeployment of a small crew.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">We always strive to communicate as accurately as possible with our
shareholders based on the best available information at any given time, and to act in the best interest of all of our shareholders. We
believe we have done so to-date and are continuing to do so today with the recent unanimous decision by the Board to enter into the transaction
with Wilks. This has been a well thought out decision following an expansive strategic review and evaluation process over the last two
years that was focused on maximizing value for all shareholders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">We believe there is an ongoing fundamental shift in how E&amp;P companies
allocate capital which, unlike previous cycles, will result in further delays in any potential recovery in the North American onshore
seismic data acquisition market, thus impacting Dawson&rsquo;s opportunities to materially increase revenue streams and maintain a cash
neutral position.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">It is a privilege to serve and work on the behalf of all of our shareholders.
There is always the possibility we are not correct in our assumptions on timing of a recovery. However, we see no evidence to suggest
any meaningful improvement in Dawson&rsquo;s activity levels for some time to come.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">While the Company&rsquo;s Board and management continue to diligently
serve the interest of the shareholders, we reiterate our recommendation for Dawson shareholders to tender their shares. We believe this
transaction provides shareholders a liquidity event and compelling value for their shares in a very difficult and challenging market.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">We are grateful for our loyal shareholders, valued customers and dedicated

factors. These risks include, but are not limited to, statements regarding the expected consummation of the acquisition, which involve
a number of risks and uncertainties, including the satisfaction of closing conditions for the acquisition (such as the tender of at least
80% of the outstanding shares of capital stock of the Company in order to close the tender offer, and approval of at least 80% of the
outstanding shares of the capital stock of the Company in order to consummate the second step merger); the possibility that the transaction
will not be completed; the impact of general economic, industry, market or political conditions; dependence upon energy industry spending;
changes in exploration and production spending by our customers and changes in the level of oil and natural gas exploration and development;
the results of operations and financial condition of our customers, particularly during extended periods of low prices for crude oil and
natural gas; the volatility of oil and natural gas prices; changes in economic conditions; the severity and duration of the COVID-19 pandemic,
related economic repercussions and the resulting negative impact on demand for oil and gas; surpluses in the supply of oil and the ability
of OPEC+ to agree on and comply with supply limitations; the duration and magnitude of the unprecedented disruption in the oil and gas
industry currently resulting from the impact of the foregoing factors, which is negatively impacting our business;&nbsp;the potential
for contract delays; reductions or cancellations of service contracts; limited number of customers; credit risk related to our customers;
reduced utilization; high fixed costs of operations and high capital requirements; operational challenges relating to the COVID-19 pandemic
and efforts to mitigate the spread of the virus, including logistical challenges, protecting the health and well-being of our employees
and remote work arrangements; industry competition; external factors affecting the Company&rsquo;s crews such as weather interruptions
and inability to obtain land access rights of way; whether the Company enters into turnkey or day rate contracts; crew productivity; the
availability of capital resources; disruptions in the global economy; and whether or not the pending transaction with Wilks will be completed.
A discussion of these and other factors, including risks and uncertainties, is set forth in the Company&rsquo;s Annual Report on Form&nbsp;10-K
that was filed with the U.S. Securities and Exchange Commission (the &ldquo;SEC&rdquo;) on March&nbsp;16, 2021 and any subsequent Quarterly
Reports on Form&nbsp;10-Q filed with the SEC. The Company disclaims any intention or obligation to revise any forward-looking statements,
whether as a result of new information, future events or otherwise.</P>
