DAWSON GEOPHYSICAL REPORTS

FOURTH QUARTER AND FULL YEAR 2015 RESULTS

MIDLAND, Texas, March 11, 2016/PR Newswire/Dawson Geophysical Company (NASDAQ: DWSN) (the “Company”) today reported preliminary financial results for its fourth quarter and full year ended December 31, 2015.

On February 11, 2015, legacy Dawson Geophysical Company and legacy TGC Industries, Inc. consummated their previously announced strategic business combination. The merger transaction was accounted for as a reverse acquisition with legacy Dawson Geophysical being deemed the accounting acquirer with the results of legacy TGC Industries, Inc. being reflected in the Company’s reported consolidated financial results only for periods from and after February 11, 2015. The merged companies adopted a calendar fiscal year ending December 31. Due to the foregoing, comparative financial results that include periods prior to February 11, 2015 are not comparable to financial results that include periods from and after February 11, 2015. As a result, the Company is including selected unaudited pro-forma financial information showing, on a pro forma basis, the effect of the business combination as if it had occurred on January 1, 2014 (together with the assumptions related thereto), at the end of this press release. Additional information regarding the business combination and its impact on the Company’s financial position will be set forth in the Company’s Form 10-K for the fiscal year ended December 31, 2015, which will be filed with the Securities and Exchange Commission on or about March 15, 2016 and will include the Company’s audited consolidated financial statements (i) as of and for the years ended December 31, 2015 and September 30, 2014, (ii) for the three months ended December 31, 2014 and (iii) for the years ended September 30, 2014 and 2013.

For the quarter ended December 31, 2015, the Company reported revenues of $55,130,000 as compared to $50,802,000 (or $76,897,000 on a pro forma basis) for the quarter ended December 31, 2014. For the fourth quarter 2015, the Company reported a net loss of $4,940,000, or $0.23 loss per share attributable to common stock, as compared to a net loss of $4,991,000 (or $7,722,000 on a pro forma basis) or $0.36 (or $0.36 on a pro forma basis) loss per share attributable to common stock for the quarter ended December 31, 2014. The Company reported EBITDA of $3,945,000 for the quarter ended December 31, 2015 compared to $2,906,000 (or $1,642,000 on a pro forma basis) for the quarter ended December 31, 2014.

For the year ended December 31, 2015, the Company reported revenues of $234,685,000 as compared to $244,304,000 (or $363,152,000 on a pro forma basis) for the year ended December 31, 2014. For the full year 2015, the Company reported a net loss of $26,279,000 or $1.27 loss per share attributable to common stock as compared to a net loss of $14,714,000 (or $15,533,000 on a pro forma basis) or $1.05 loss per share (or $0.73 on a pro forma basis) attributable to common stock for the year ended December 31, 2014. The Company reported EBITDA of $7,488,000 for the year-ended December 31, 2015 compared to $20,776,000 (or $26,382,000 on a pro forma basis) for the year-ended December 31, 2014. Included in the yearly results for December 31, 2015 and December 31, 2014 were approximately $3,314,000 and $3,125,000, respectively, of transaction costs related to the completed business combination with TGC Industries, Inc.

Stephen C. Jumper, President and CEO, said, “2015 was both exciting and difficult for our Company. We are very pleased to have completed our strategic business combination on February 11, 2015 with TGC Industries. The combination brings together two of the strongest companies in the industry, the benefits of which are well described in earlier Company filings. 2015 was also a difficult year as decreasing commodity prices negatively impacted demand for services across North America as our clients significantly reduced their capital budgets. Despite the current economic conditions, we are confident that the combination strategically positions Dawson Geophysical to emerge from the downturn as a robust company. Our balance sheet remains strong as we continue to pay down our already low level of short-term debt. Our equipment base is state-of-the-art and among the best in the industry. We continue to refine our personnel base to position the company to react quickly as commodity prices improve.”

Mr. Jumper continued, “The Company operated approximately eight to ten crews in the United States with limited activity in Canada during the fourth quarter of 2015. During the fourth quarter, WTI oil prices continued their slide, ending the year near $38 per barrel and reaching as low as near $27 per barrel during the first quarter of 2016. Since that time, oil prices have increased to their current level of near $38 per barrel. As a result, demand for services has continued to decline, several near term projects were delayed for a variety of reasons including final approval of project funding, project partnership agreements among our clients and delays in securing land access agreements. Economic uncertainty continues to delay the final approval of projects. In November of 2015, we anticipated operating eight to ten crews in the United States well into the first quarter of 2016. Based on currently available information, however, we anticipate operating four to six crews in the United States into the second quarter of 2016. Currently, visibility beyond the second quarter is limited given the continued fluctuations in oil prices. We are currently operating two crews in the seasonal Canadian market which concludes in the March 2016 time frame. In response to further deterioration of current market conditions, we have reduced head count an additional 25% since the beginning of 2016 and upper management have taken salary reductions of 5 to 25 percent for 2016. Short term incentive plans are suspended and we continue to explore other appropriate cost reduction options.”

Capital expenditures for 2015 totaled $6,920,000, which was below the previously announced $10 million maintenance capital budget approved by the Board of Directors. The Company anticipates a capital budget of less than $10,000,000 for 2016 primarily dedicated to maintenance capital items and the replacement of recording channels lost in the spring floods of 2015. The Company’s balance sheet remains strong at December 31, 2015 with approximately $58,009,000 of cash and cash equivalents and short-term investments, $71,049,000 of working capital, and $10,691,000 of debt and capital lease obligations.

Mr. Jumper concluded, “Despite the challenging environment, we continue to work with several of our clients on potential projects for 2016. Our experience working through previous downturns, combined with our strong balance sheet, a state-of-the-art equipment base, and the most experienced and talented workforce in the industry, positions us to successfully navigate the current downturn. All of these factors in conjunction with the strategic business combination with TGC position Dawson to respond rapidly as market conditions improve.”

Non-GAAP Financial Measures

In an effort to provide investors with additional information regarding the Company’s preliminary and unaudited results as determined by GAAP, the Company has included in this press release information about the Company’s EBITDA, a non-GAAP financial measure as defined by Regulation G promulgated by the U.S. Securities and Exchange Commission. The Company defines EBITDA as net income (loss) plus interest expense, interest income, income taxes, depreciation and amortization expense. The Company uses EBITDA as a supplemental financial measure to assess:

·                  the financial performance of its assets without regard to financing methods, capital structures, taxes or historical cost basis;

·                  its liquidity and operating performance over time in relation to other companies that own similar assets and that the Company believes calculate EBITDA in a similar manner; and

·                  the ability of the Company’s assets to generate cash sufficient for the Company to pay potential interest costs.

The Company also understands that such data are used by investors to assess the Company’s performance.  However, the term EBITDA is not defined under generally accepted accounting principles, and EBITDA is not a measure of operating income, operating performance or liquidity presented in accordance with generally accepted accounting principles.  When assessing the Company’s operating performance or liquidity, investors and others should not consider this data in isolation or as a substitute for net income (loss), cash flow from operating activities or other cash flow data calculated in accordance with generally accepted accounting principles. In addition, the Company’s EBITDA may not be comparable to EBITDA or similar titled measures utilized by other companies since such other companies may not calculate EBITDA in the same manner as the Company. Further, the results presented by EBITDA cannot be achieved without incurring the costs that the measure excludes: interest, taxes, depreciation and amortization. A reconciliation of the Company’s EBITDA to its net loss is presented in the table following the text of this press release.

In accordance with the Safe Harbor provisions of the Private Securities 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’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; the volatility of oil and natural gas prices; high fixed costs of operations and high capital requirements; operational disruptions; changes in economic conditions; industry competition; reduced utilization; the potential for contract delays, reductions or cancellations of service contracts; external factors affecting the Company’s crews such as weather interruptions and inability to obtain land access rights of way; disruptions in the global economy; whether the Company enters into turnkey or dayrate contracts; crew productivity;  the availability of capital resources; limited number of customers; and credit risk related to our customers. A discussion of these and other factors, including risks and uncertainties, is set forth in the Company’s Form 10-Q that was filed with the Securities and Exchange Commission on November 6, 2015 and in Exhibit 99.5 to the Company’s Form 8-K/A that was filed with the Securities and Exchange Commission on April 30, 2015. The Company disclaims any intention or obligation to revise any forward-looking statements, whether as a result of new information, future events or otherwise.
