<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">MIDLAND, Texas, May 13, 2021/PR Newswire/Dawson Geophysical Company
(NASDAQ: DWSN) (the &ldquo;Company&rdquo;) today reported unaudited financial results for its first quarter ended March 31, 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">For the first quarter ended March 31, 2021, the Company reported revenues
of $11,748,000, a decrease of approximately 70% compared to $38,979,000 for the quarter ended March 31, 2020. For the first quarter of
2021, the Company reported a net loss of $5,228,000, or $0.22 loss per share of common stock, compared to net income of $993,000, or $0.04
per share of common stock, for the quarter ended March 31, 2020. The Company reported negative EBITDA of $1,858,000 for the quarter ended
March 31, 2021 compared to EBITDA of $5,831,000 for the quarter ended March 31, 2020.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The first fiscal quarter of 2021 was difficult as indicated in our
2020 year-end earnings release. The Company operated one seismic data acquisition crew in the United States (&ldquo;U.S.&rdquo;) with
limited utilization and one crew in Canada. The near term outlook for seismic data acquisition activity in the U.S. remains challenged
with historically low levels of crew and bid activity. Based on currently available information, the Company anticipates limited crew
activity in the second quarter with up to one crew operating in the U.S. with periods of low utilization in the back half of 2021. Currently,
the Company does not have a crew deployed in the U.S. and the Canadian season concluded at the end of the first quarter.</P>

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

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Stephen C. Jumper, President and Chief Executive Officer, said, &ldquo;Since
the onset of the COVID-19 pandemic over a year ago, the seismic data acquisition market along with other oil field services remain challenged
in the U.S. and Canada. While there are encouraging signs of recovery in certain oil field services, such as drilling and completion services,
current demand for seismic related services remains at very low levels. In recent months, oil prices have improved to the $60 per barrel
range as oil demand has increased with states beginning to further open businesses, air travel increasing and the rollout of the COVID-19
vaccines. The U.S. rig count, currently at 448, is steadily improving, as is the number of hydraulic fracturing crews. Based on currently
available information, we anticipate seismic data acquisition activity in the lower 48 to reach a low in the second quarter and into the
third quarter of 2021 with slight improvement later in 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">As we have stated in prior earnings releases, demand for seismic data
acquisition in recent cycles lags behind the recovery in drilling and completion activity as Exploration and Production companies initially
deploy capital into such services and work through their inventory of drillable projects. The same is true on the front side of a downturn
as drilling and completion services are scaled back, while currently active seismic related projects continue, as seen in 2020 where our
activity levels remained relatively high through the second quarter and into the third quarter after the onset of the COVID-19 pandemic.
The timing of a return to an increase in demand for seismic services in 2021 is further delayed due to the depth of the most recent downturn,
slow recovery of capital budget increases as oil prices remained depressed into 2021, a larger than typical post downturn inventory of
drilling projects, and slower recovery of rig count to work through the inventory back log.</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">During the latter part of 2018 and continuing into the first half of
2020, the Company successfully acquired multiple high density, large channel count projects in certain areas of the Permian Basin. These
fully processed data sets first became available to the industry in late 2019 and continue into 2021. Early results of these data sets
indicate substantially improved subsurface image quality compared to prior seismic data sets, examples of which are just beginning to
become public. The increases in data quality and imagery are currently being utilized for improved well planning, geo-steering of long
lateral well bores, geo-hazard identification and avoidance, enhanced reservoir definition and rock property description between well
data samples and strategic placement of disposal well locations. As the industry begins to recognize and appreciate the value of these
high density, large channel count surveys, we believe demand for such surveys will improve. The Company&rsquo;s state-of-the-art equipment
base allows us to deploy multiple large channel count crews when demand does improve.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Jumper continued, &ldquo;In our continuing response to these difficult
times, the Company significantly limited capital budget spending, reduced fixed and variable operating expenses, and implemented a comprehensive
equipment maintenance program in preparation for a rapid response to increased activity levels. In addition, the Company maintains its
commitment to its robust Health, Safety and Environmental program, ongoing client relationships and product quality.&rdquo;</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">The Company made no capital expenditures during the first quarter of
2021. As stated in our December 31, 2020 earnings release, the Company&rsquo;s Board of Directors has approved an initial capital budget
of $1,000,000 for 2021. The Company&rsquo;s balance sheet remains strong with $46,954,000 of cash, restricted cash and short term investments
and $49,714,000 of working capital as of March 31, 2021. The Company is nearly debt free, with notes payable and finance leases of $587,000
as of March 31, 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">Jumper concluded, &ldquo;While today&rsquo;s conditions in the seismic
data acquisition market remain challenged and are likely to remain so in the coming months, we are encouraged by the overall improvement
in both the economy and the oil field service sector. Improvement in drilling and completion activities helps set the stage for a successful
recovery in the seismic data acquisition sector. I thank our hard-working employees, valued customers and trusted shareholders as we work
our way through these difficult conditions and toward better times ahead.&rdquo;</P>

Litigation Reform Act of 1995, the Company cautions that statements in this press release which are forward-looking and which provide
other than historical information involve risks and uncertainties that may materially affect the Company&rsquo;s actual results of operations.
Such forward-looking statements are based on the beliefs of management as well as assumptions made by and information currently available
to management. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain
factors. These risks include, but are not limited to, 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;
and disruptions in the global economy. 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 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.&nbsp;</P>
