NOTES TO FINANCIAL STATEMENTS

June 30, 2009

NOTE A

BASIS OF PRESENTATION

The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America for interim financial information and the instructions to Form 10-Q. Accordingly, they do not include all of the financial information and footnotes required by generally accepted accounting principles for complete financial statements. References to “we,” “us,” “our,” “its,” or the “Company” refer to TGC Industries, Inc. and our subsidiaries.

REVENUE RECOGNITION

Seismic Surveys

The Company provides seismic data acquisition survey services to its customers under general service agreements which define certain obligations for the Company and for its customers. A supplemental agreement setting forth the terms of a specific project, which may be cancelled by either party upon 30 days’ advance written notice, is entered into for every project. These supplemental agreements are either “turnkey” agreements providing for a fixed fee to be paid for each unit of seismic data acquired or “term” agreements providing for a fixed hourly, daily, or monthly fee during the term of the project. The duration of these projects will vary from a few days to several months. The Company recognizes revenue when services are performed under both types of agreements. Services are defined as the commencement of data acquisition. Under turnkey agreements, the total number of units of seismic data to be gathered is set forth in the agreement, and revenue is recognized as services are performed on a per unit of seismic data acquired rate. Under term agreements, revenue is recognized as services are performed based on the time worked rate provided in the term agreement. Under both turnkey and term agreements, cost of earned revenue is recognized by multiplying total estimated agreement cost by the percentage-of-completion of the agreement. The excess of that amount over the cost of earned revenue reported in prior periods is recognized as cost of earned revenue for the period. Agreements are not segmented or combined for purposes of calculating percentage of completion. The asset “Cost and estimated earnings in excess of billings on uncompleted contracts” represents cost incurred on turnkey agreements in excess of billings on those agreements. The liability “Billings in excess of costs and estimated earnings on uncompleted contracts” represents billings on turnkey agreements in excess of cost on those agreements. Claims have been negligible in the six-month period ended June 30, 2009 and the year ended December 31, 2008.

Gravity Data

The Company owns a data bank which contains gravity data, and to a lesser extent magnetic data, from many of the major oil and natural gas producing areas located within the United States. When an order for gravity data is received, the portion of gravity data requested by the customer is prepared in digital format for licensing and shipment to the customer. This process is performed by an employee in the Company’s headquarters office and is normally completed within a few days. In addition, the licensing of gravity data is not a material part of the Company’s revenue. Gravity data revenue during the six-month period ended June 30, 2009, was approximately $11,900. Gravity revenue for the year ended December 31, 2008, was approximately $46,100.

CHANGE IN ACCOUNTING ESTIMATE

Management evaluates its estimates on a routine basis. Effective July 1, 2007, the Company revised the estimated useful lives of certain seismic equipment and related components. The Company purchased this new equipment from November 2004 through June 2007. Management employed this equipment in operations for an average holding period of one year as of July 1, 2007. Based on the information gained from operations during this holding period, management believes that this equipment will benefit periods ranging from 5 to 7 years, beginning at the point the assets were originally placed in service. The original estimated useful lives ranged from 3 to 5 years.

The net book value of this equipment at June 30, 2007, was not modified and is amortized over the revised estimated useful lives of the equipment. The Company does not believe that this equipment will become obsolete at the end of the original estimate and has revised the estimated lives of these assets. The impact on depreciation expense, net income, and earnings per share for the three and six months ended June 30, 2009, is:

NOTE B — MANAGEMENT PRESENTATION

In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of financial position, results of operations, and changes in financial position have been included. The results of the interim periods are not necessarily indicative of results to be expected for the entire year. For further information, refer to the financial statements and the footnotes thereto included in the Company’s Annual Report for the year ended December 31, 2008, filed on Form 10-K.

NOTE C — EARNINGS PER SHARE

Basic earnings per common share are based upon the weighted average number of shares of common stock (“common shares”) outstanding. Diluted earnings per share are based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants, and convertible securities. All earnings per common share for the three-month and six-month periods ended June 30, 2009 and 2008 have been adjusted for the 5% stock dividend paid on May 12, 2009, to shareholders of record as of April 28, 2009.

NOTE D — DIVIDENDS

On April 16, 2009, the Company declared a five percent (5%) stock dividend on its outstanding common shares. The 5% stock dividend was paid on May 12, 2009, to shareholders of record as of April 28, 2009. Cash in lieu of fractional shares in the total amount of $385.50 was paid to shareholders based on the last sales price of the Company’s common shares on the record date.

NOTE E — INCOME TAXES

Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for tax purposes. In addition, the Company paid, during the first six months of 2009, federal and various state estimated income taxes for tax year 2009, as well as various state income taxes for tax year 2008.

NOTE F — STOCK-BASED COMPENSATION

Prior to January 1, 2006, the Company accounted for its stock options under the recognition and measurement principles of APB Opinion No. 25 and related interpretations. Accordingly, no stock-based employee compensation cost was reflected in our financial statements prior to January 1, 2006, since all options to purchase common stock of the Company have an exercise price equal to, or greater than, the market value of the underlying common stock on the date of grant.

Effective January 1, 2006, the Company implemented Statement of Financial Accounting Standards (SFAS) No. 123R, “Share Based Payment (SFAS 123R),” for stock-based compensation awards granted after that date and for unvested awards outstanding at that date using the modified prospective application method. We recognize the fair value of the stock-based compensation awards as wages in the Statements of Income on a straight-line basis over the vesting period. Such implementation is expected to have minimal impact on our results of operations, financial position, and liquidity. The adoption of SFAS 123R resulted in the recognition of compensation expense, relative to stock-based awards, in wages in the Statements of Income of approximately $78,000 and $106,000 (less than $0.01 per share) for the three months ended June 30, 2009 and 2008, respectively, and approximately $223,000 and $210,000 (or approximately $.01 per share) for the six months ended June 30, 2009 and 2008, respectively. In accordance with the modified prospective application method permitted by SFAS 123R, prior period amounts have not been restated to reflect the recognition of stock-based compensation costs.

As of June 30, 2009, there was approximately $520,000 of unrecognized compensation expense related to our two share-based compensation plans. In June 2009, the Stock Awards Committee, a committee of the Board of Directors that administers the Company’s Stock Awards Plan, granted 5,000 shares of restricted stock. The shares of restricted stock were issued in the name of the grantee and have restrictive legends prohibiting their sale prior to vesting. One-third (1/3) of the granted restricted shares will vest each year on the anniversary of the grant.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

The following discussion and analysis should be read in conjunction with our financial statements and related notes thereto included elsewhere in this Form 10-Q. Portions of this document that are not statements of historical or current fact are forward-looking statements that involve risk and uncertainties, such as statements of our plans, objectives, expectations, and intentions. The cautionary statements made in this Form 10-Q should be read as applying to all related forward-looking statements wherever they appear in this Form 10-Q. Our actual results could differ materially from those anticipated in the forward-looking statements. Factors that could cause our actual results to differ materially from anticipated results include those discussed in Part II, Item 1A. “RISK FACTORS.”

Forward Looking Statements

This report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact included in this report regarding the Company’s strategies and plans for growth are forward-looking statements. These forward-looking statements are often characterized by the terms “may,” “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” “target,” and other words and terms of similar meanings and do not reflect historical facts. Although management believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will prove to have been correct. Important factors that could cause actual results to differ materially from such expectations are disclosed in the Company’s Securities and Exchange Commission filings, and include, but are not limited to, the dependence upon energy industry spending for seismic services, the unpredictable nature of

Table of Contents

forecasting weather, the potential for contract delay or cancellation, the potential for fluctuations in oil and gas prices, the availability of capital resources, and the current economic downturn which could adversely affect our revenues and cash flow if our customers, and/or potential customers, become unable to pay, or must delay payment of, amounts owing to the Company because such customers are not successful in generating revenues or are precluded from securing necessary financing. The forward-looking statements contained herein reflect the current views of the Company’s management, and the Company assumes no obligation to update the forward-looking statements or to update the reasons actual results could differ from those contemplated by such forward-looking statements.

Executive Overview

The Company is a leading provider of seismic data acquisition services throughout the continental United States. We currently operate four seismic crews. These seismic crews supply seismic data to companies engaged in the domestic exploration and development of oil and natural gas on land and in land-to-water transition areas. Our customers rely on seismic data to identify areas where subsurface conditions are favorable for the accumulation of existing hydrocarbons, to optimize the development and production of hydrocarbon reservoirs, to better delineate existing oil and natural gas fields, and to augment reservoir management techniques.

We acquire geophysical data using the latest in 3-D survey techniques. We introduce acoustic energy into the ground by using vibration equipment or dynamite detonation, depending on the surface terrain and subsurface requirements. The reflected energy, or echoes, is received through geophones, converted into a digital signal at a multi-channel recording unit, and then transmitted to a central recording vehicle. Subsurface requirements dictate the number of channels necessary to perform our services. With our state-of-the-art seismic equipment, including computer technology and multiple channels, we acquire, on a cost effective basis, immense volumes of seismic data that when processed and interpreted produce more precise images of the earth’s subsurface. Our customers then use our seismic data to generate 3-D geologic models that help reduce finding costs and improve recovery rates from existing wells.

We provide our seismic data acquisition services primarily to domestic onshore oil and natural gas exploration and development companies for use in the onshore drilling and production of oil and natural gas in the continental United States. The main factors influencing demand for seismic data acquisition services in our industry are the level of drilling activity by oil and natural gas companies and the sizes of such companies’ exploration and development budgets, which, in turn, depend largely on current and anticipated future crude oil and natural gas prices and depletion rates.

Our customers are major and independent oil and natural gas exploration and development companies. The services we provide to our customers vary according to the size and needs of each customer. Our services are marketed by supervisory and executive personnel who contact customers to determine their needs and respond to customer inquiries regarding the availability of crews. Contacts are based principally upon professional relationships developed over a number of years. There are a number of consultants in the oil and natural gas industry who process and interpret seismic data for oil and natural gas companies. These consultants can have an influence in determining which company their customers use to acquire seismic data.

The acquisition of seismic data for the oil and natural gas industry is a highly competitive business. Contracts for such services generally are awarded on the basis of price quotations, crew experience, and the availability of crews to perform in a timely manner, although factors other than price, such as crew safety performance history, and technological and operational expertise, are often determinative. Our competitors include companies with financial resources that are significantly greater than our own as well as companies of comparable and smaller size. Our primary competitors are Dawson Geophysical Company, Geo Kinetics, Inc., and CGG-Veritas. These competitors are publicly-traded companies with long operating histories which field numerous crews and work in a number of different regions and terrain. In addition to the previously named companies, we also compete for

Table of Contents

projects from time to time with smaller seismic companies which operate in local markets with only one or two crews and often specialize in specific regions or type of operations. We believe that our long-term industry expertise, the customer relationships developed over our history, and our financial stability give us an advantage over most of our competitors in the industry.

Results of Operations

Six Months Ended June 30, 2009, Compared to Six Months Ended June 30, 2008 (Unaudited)

Revenues. Our revenues were $58,602,011 for the six months ended June 30, 2009, compared to $41,091,078 for the same period of 2008, an increase of 42.6%. This increase in revenues was attributable to several factors including an increase in crew productivity, additional shot-hole revenue, favorable weather conditions, our operation of nine seismic crews during the first three months of 2009 compared to eight crews for the same period of 2008, and first quarter 2009 revenues exceeding first quarter 2008 revenues by $13,540,187.

Cost of services. Our cost of services was $37,810,163 for the six months ended June 30, 2009, compared to $27,426,577 for the same period of 2008, an increase of 37.9%. This increase was principally attributable to the corresponding increase in revenue and increased operating expenses due to additional shot-hole projects. As a percentage of revenues, cost of services was 64.5% for the six months ended June 30, 2009 compared to 66.7% for the same period of 2008.

Selling, general, and administrative expenses. SG&A expenses were $2,141,866 for the six months ended June 30, 2009, compared to $1,919,951 for the same period of 2008, an increase of 11.6%. This increase was primarily attributable to additional expenses associated with additional selling and administrative personnel during the six months ended June 30, 2009, compared to the same period of 2008. SG&A expense as a percentage of revenues was 3.7% for the six months ended June 30, 2009, compared with 4.7% for the same period of 2008.

Depreciation and amortization expense. Depreciation and amortization expense was $7,432,753 for the six months ended June 30, 2009, compared to $6,681,347 for the same period of 2008, an increase of 11.2%. This increase was primarily attributable to additions of new seismic recording equipment and vibration vehicles. Depreciation and amortization expense as a percentage of revenues was 12.7% for the six months ended June 30, 2009, compared to 16.3% for the same period of 2008. For further information, refer to Note A — Change in Accounting Estimate found above.

Income from operations. Income from operations was $11,217,229 for the six months ended June 30, 2009, compared to $5,063,203 for the same period of 2008, an increase of 121.5%. This increase was primarily attributable to several factors including increased crew productivity, additional shot-hole revenue, favorable weather conditions, and our operation of nine seismic crews during the first three months of 2009 compared to eight crews for the same period of 2008. EBITDA increased $6,905,432 to $18,649,982 for the six months ended June 30, 2009, from $11,744,550 for the same period of 2008, an increase of 58.8%. This increase was a result of those same factors mentioned above. For a definition of EBITDA, a reconciliation of EBITDA to net income, and discussion of EBITDA, please refer to the section entitled “EBITDA” found below.

Interest expense. Interest expense was $536,960 for the six months ended June 30, 2009, compared to $369,924 for the same period of 2008, an increase of 45.2%. This increase was primarily attributable to the additional debt incurred for the purchase of our eighth ARAM ARIES recording system, 7,000 additional recording channels, and 13 new vibration vehicles.

Revenues. Our revenues were $22,591,134 for the three months ended June 30, 2009, compared to $18,620,388 for the same period of 2008, an increase of 21.3%. This increase in revenues was principally attributable to an increase in crew productivity, additional shot-hole revenue, and favorable weather conditions as two of our eight seismic acquisition crews were idle for most of the second quarter of 2008.

Cost of services. Our cost of services was $15,565,041 for the three months ended June 30, 2009, compared to $12,550,975 for the same period of 2008, an increase of 24.0%. This increase was primarily attributable to the increase in revenues for the three months ended June 30, 2009, compared to the same period of 2008, and increased operating expenses due to additional shot-hole projects. As a percentage of revenues, cost of services was 68.9% for the three months ended June 30, 2009, compared to 67.4% for the same period of 2008.

Selling, general, and administrative expenses. SG&A expenses were $968,333 for the three months ended June 30, 2009, compared to $985,681 for the same period of 2008, a decrease of 1.8%. SG&A expense as a percentage of revenues was 4.3% for the three months ended June 30, 2009, compared with 5.3% for the same period of 2008.

Depreciation and amortization expense. Depreciation and amortization expense was $3,633,316 for the three months ended June 30, 2009, compared to $3,404,927 for the same period of 2008, an increase of 6.7%. This increase was primarily attributable to additions of new seismic recording equipment and vibration vehicles. See Note A of Notes to Financial Statements in Item 1. Depreciation and amortization expense as a percentage of revenues was 16.1% for the three months ended June 30, 2009, compared to 18.3% for the same period of 2008. For further information, refer to Note A — Change in Accounting Estimate found above.

Income from operations. Income from operations was $2,424,444 for the three months ended June 30, 2009, compared to $1,678,805 for the same period of 2008, an increase of 44.4%. This increase was primarily attributable to an increase in revenues and a decrease in SG&A expenses, partially offset by an increase in cost of services and depreciation and amortization expense. EBITDA increased $974,028 to $6,057,760 for the three months ended June 30, 2009, from $5,083,732 for the same period of 2008, an increase of 19.2%. This increase was a result of those factors mentioned above.

Interest expense. Interest expense was $268,313 for the three months ended June 30, 2009, compared to $208,542 for the same period of 2008, an increase of 28.6%. This increase was primarily attributable to the additional debt incurred for the purchase of our eighth ARAM ARIES recording system, 7,000 additional recording channels, and 13 new vibration vehicles.

Income tax expense. Income tax expense was $913,862 for the three months ended June 30, 2009, compared to $602,543 for the same period of 2008. The effective tax rate was 42.4% for the three months ended June 30, 2009, compared to 41.0% for the same period of 2008. See Note E of Notes to Financial Statements in Item 1.

EBITDA

We define EBITDA as net income plus interest expense, income taxes, and depreciation and amortization expense. We use EBITDA as a supplemental financial measure to assess:

Table of Contents

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

· our liquidity and operating performance over time and in relation to other companies that own similar assets and that we believe calculate EBITDA in a manner similar to us; and

· the ability of our assets to generate cash sufficient for us to pay potential interest costs.

We also understand that such data is used by investors to assess our performance. However, EBITDA is not a measure of operating income, operating performance, or liquidity presented in accordance with generally accepted accounting principles. When assessing our operating performance or our liquidity, you should not consider this data in isolation or as a substitute for our net income, cash flow from operating activities, or other cash flow data calculated in accordance with generally accepted accounting principles. EBITDA excludes some, but not all, items that affect net income and operating income, and these measures may vary among other companies. Therefore, EBITDA as presented below may not be comparable to similarly titled measures of other companies. Further, the results presented by EBITDA cannot be achieved without incurring the costs that the measure excludes: interest expense, income taxes, and depreciation and amortization.

The following table reconciles our EBITDA to our net income:

	Three Months Ended				Six Months Ended

Liquidity and Capital Resources

Cash Flows

Cash flows from operating activities.

Net cash provided by operating activities was $10,673,262 for the six months ended June 30, 2009, compared to $13,217,004 for the same period of 2008. The $2,543,742 decrease during the first six months of 2009 from the same period of 2008 was principally attributable to the timing of billings and revenue recognition, the collections of accounts receivable, the timing of receipt and payment of invoices, federal and state income taxes payable, and the mix of contracts.

Working capital increased $9,865,864 to $26,834,907 as of June 30, 2009, from the December 31, 2008 working capital of $16,969,043. This increase was primarily due to a $6,508,185 increase in cash and cash equivalents, a $3,763,402 increase in cost and estimated earnings in excess of billings on uncompleted contracts, a $1,177,085 increase in prepaid expenses and other, a $1,516,103 decrease in trade accounts payable, and a $5,754,963 decrease in billings in excess of costs and estimated earnings on uncompleted contracts partially offset by a decrease in trade accounts receivable of $1,849,610, a decrease in prepaid federal income taxes of $1,220,154, a $1,077,909 increase in accrued liabilities, an increase in federal and state income taxes payable of $3,511,946, and an increase in the current portion of debt obligations of $1,194,255.

Cash flows used in investing activities.

Net cash used in investing activities was $464,910 for the six months ended June 30, 2009, and $1,433,131 for the six months ended June 30, 2008. This decrease was due primarily to a decrease in capital expenditures of $861,901.

Cash flows used in financing activities.

Net cash used in financing activities was $3,700,167 for the six months ended June 30, 2009, and $4,113,739 for the six months ended June 30, 2008. The decrease was due primarily to a decrease in the amount of principal payments on our outstanding notes payable of $270,414 and a decrease in the amount of principal payments on capital lease obligations of $133,116

Capital expenditures.

During the six months ended June 30, 2009, the Company acquired $1,114,678 of additional equipment and vehicles. Cash of $707,080 and capital lease obligations from a vehicle leasing company of $407,598 were used to finance these acquisitions. Although we do not budget for our capital expenditures, we may purchase additional equipment during 2009 should the demand for our services increase.

Liquidity

Our primary source of liquidity is cash generated from operations and short-term borrowings from commercial banks and equipment lenders. Based on current forecasts, we believe that we have sufficient available cash and borrowing capacity to fund our working capital needs over the next twelve months.

Capital Resources

Since 2005, we have relied on cash generated from operations, short-term borrowings from commercial banks and equipment lenders, and proceeds from a public offering of our common stock to fund our working capital requirements and capital expenditures.

In April of 2005 we entered into a revolving credit agreement with a commercial bank. Effective September 16, 2006, we renewed our revolving credit agreement and increased the borrowing limit from $3,500,000 to $5,000,000. The borrowing limit under the revolving credit agreement remains at $5,000,000 and was renewed on September 16, 2007, and September 16, 2008, respectively. The revolving line of credit agreement does not expire until September 16, 2009. Our obligations under this agreement are secured by a security interest in our accounts receivable. Interest on the outstanding amount under the revolving credit agreement is payable monthly at the prime rate of interest. The credit loan agreement provides for non-financial and financial covenants including a minimum debt service coverage ratio in excess of 2.0 to 1.0 and a ratio of debt to worth not in excess of 1.25 to 1.0. As of June 30, 2009 we had no borrowings outstanding under the revolving credit agreement.

In April of 2004 we executed an addendum to our lease of a facility in Plano, Texas, that includes approximately 10,500 square feet of office and warehouse space and an outdoor storage area of approximately 20,000 square feet. This facility is used to repair geophysical equipment and housed our corporate offices until September of 2006. In September of 2005 we leased an additional facility, in Plano, Texas, with approximately 10,000 square feet of office and warehouse space and an additional 10,000 square feet of outdoor storage. This facility is used primarily to repair geophysical equipment. In January of 2006 we leased a 600-square foot facility in Houston, Texas, to be used as a sales office. In July of 2006 we entered into a lease for 7,269 square feet of

Table of Contents

office space located in Plano, Texas. In September of 2006 we relocated our corporate offices to this facility. This lease was modified in September 2008 to include an additional 1,254 square feet for a total of 8,523 square feet of office space located in Plano, Texas. In October of 2006 we leased an 800-square foot facility in Oklahoma City, Oklahoma, to be used as a sales office. In September of 2007, we leased a 1,130-square foot facility in Denver, Colorado, to be used as a sales office. We will close the Denver office upon expiration of the lease agreement on August 31, 2009. In September of 2008, we leased a 400-square foot facility in Pratt, Kansas, to be used as a permit office. In November of 2008, we vacated our two Plano repair, warehouse and outdoor storage facilities and moved to a leased repair, warehouse, and outside storage facility in Denison, Texas. The Denison, Texas, facility consists of one 5,000-square foot building, two 10,000-square foot adjacent buildings and an outdoor storage area of approximately 60,500 square feet.

Contractual Obligations

We believe that our capital resources, including our short-term investments, funds available under our revolving credit agreement, and cash flow from operations will be adequate to meet our current operational needs. We believe that we will be able to finance our 2009 capital expenditures through cash flow from operations, borrowings from commercial lenders, and the funds available under our line of credit loan agreement. However, our ability to satisfy working capital requirements, meet debt repayment obligations, and fund future capital requirements will depend principally upon our future operating performance which is subject to the risks inherent in our business, and will also depend on the extent to which the current recession adversely affects the ability of our customers, and/or potential customers, to pay promptly amounts owing to the Company under their service contracts with us.

Off-Balance Sheet Arrangements

As of June 30, 2009, we had no off-balance sheet arrangements.

Critical Accounting Policies

A discussion of our critical accounting policies can be found in our Annual Report on Form 10-K for the fiscal year ended December 31, 2008. There have been no material changes to these policies (including critical accounting estimates and assumptions or judgments affecting the application of those estimates and assumptions) during the first six months of 2009.

Recently Issued Accounting Pronouncements

A discussion of recently issued accounting pronouncements can be found in our Annual Report on Form 10-K for the fiscal year ended December 31, 2008.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We have not entered into any hedging agreements or swap agreements. Our principal market risks include fluctuations in commodity prices which affect demand for and pricing for our services and the risk related to the concentration of our customers in the oil and natural gas industry. Since all of our customers are involved in the oil and natural gas industry, there may be a positive or negative effect on our exposure to credit risk because our customers may be similarly affected by changes in economic and industry conditions. For the year ended December 31, 2008, our top two customers accounted for approximately 14.4% and 12.3% of our revenues.
