NOTES TO FINANCIAL STATEMENTS (UNAUDITED) June 30, 2002 NOTE A -- BASIS OF PRESENTATION The accompanying unaudited financial statements have been prepared in accordance with the instructions to Form 10-QSB and therefore do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and changes in financial position in conformity with accounting principles generally accepted in the United States of America. 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, 2001 filed on Form 10-KSB. NOTE C -- EARNINGS (LOSS) PER SHARE Basic earnings (loss) per common share are based upon the weighted average number of shares of common stock outstanding. Diluted earnings (loss) 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. The effect of preferred stock dividends on the amount of loss available to common stockholders was $.01 and $.07 for the three months ended June 30, 2002 and 2001, respectively, and $.03 and $.14 for the six months ended June 30, 2002 and 2001 respectively. Outstanding warrants that were not included in the diluted calculation because their effect would be anti-dilutive totaled 850,000 for each of the three and six month periods ended June 30, 2002, and 2001. Outstanding options that were not included in the diluted calculation because their effect would be anti-dilutive totaled 232,100 for each of the three and six month periods ended June 30, 2002; 260,987 and 285,997 for the three and six month periods ended June 30, 2001, respectively. 7 TGC INDUSTRIES, INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) June 30, 2002 (Continued) NOTE D DIVIDENDS Holders of the Company's Series C 8% Convertible Exchangeable Preferred Stock ("Series C Preferred Stock") will receive, when, as and if declared by the Board of Directors of the Company, dividends at a rate of 8% per annum. The dividends are payable semi-annually during January and July of each year. At June 30, 2002, cumulative dividends of approximately $81,340 were in arrears on the Company's Series C Preferred Stock. Holders of the Company's 8-1/2% Senior Convertible Preferred Stock (the "Senior Preferred Stock") will receive, when, as and if declared by the Board of Directors of the Company, dividends at a rate of 8-1/2% per annum. The dividends are payable semi-annually during June and December of each year. Dividends paid during 2000, on the Senior Preferred Stock, were paid in additional shares of Senior Preferred Stock, in accordance with the terms of the Statement of Resolution Establishing the Senior Preferred Stock. In addition, the holders elected to receive payment of the June and December 2001, and the June 2002 dividends in additional shares of Senior Preferred Stock. At June 30, 2002, there were no dividends in arrears on the Company's Senior Preferred Stock. NOTE E CONVERSION OF SERIES C PREFERRED STOCK At a November 30, 2001 meeting, the Company's Board of Directors voted to reduce, on a post-reverse split basis, the conversion price of the Series C Preferred Stock from $2.00 per share of Common Stock to $1.61 per share of Common Stock. In addition, the Board of Directors voted to extend the conversion price increase date of the Series C Preferred Stock from the close of business on December 31, 2001 until the close of business on January 31, 2002. As a result, the conversion price was $1.61 per share of Common Stock if converted prior to the close of business on January 31, 2002. After January 31, 2002, and prior to the close of business on December 31, 2002, the conversion price per share of Common Stock shall be $3.75. Thereafter, the conversion price per share of Common Stock shall be $6.00. As of January 31, 2002, a total of 1,092,250 shares of Series C Preferred Stock had been converted into shares of Common Stock. The 58,100 shares of Series C Preferred Stock that were not converted as of January 31, 2002, remain outstanding at July 31, 2002. Had these conversions taken place at the beginning of 2001, loss per common share would have been reduced by $0.12 and $0.31 for the three and six month periods ended June 30, 2001, respectively. 8 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. RESULTS OF OPERATIONS TGC Industries, Inc. ("TGC") was unable to maintain its first quarter 2002 profitability during the second quarter. As a result, TGC reported a net loss, before dividend requirements on preferred stock, of $(264,151) on revenue of $1,654,409, for the three month period ended June 30, 2002 compared with a net loss, before dividend requirements on preferred stock, of $(292,945) on revenue of $2,573,480 for the same period of 2001. Loss per common share, on a basic and diluted basis, was $(.06) for the three month period ended June 30, 2002, compared with a loss per common share of $(.19) for the same period of 2001. For the six month period ended June 30, 2002, TGC reported a net loss, before dividend requirements on preferred stock, of $182,439 on revenue of $4,572,269, compared with a net loss, before dividend requirements on preferred stock, of $834,315 on revenue of $3,455,632 for the same period of 2001. Loss per common share, on a basic and diluted basis, was $.06 for the six month period ended June 30, 2002, compared with a loss per common share of $.49 for the same period of 2001. As a result of reporting a loss for the three and six month periods ended June 30, 2002 and 2001, the number of common shares used in the diluted loss per share computation does not include any common shares issuable for stock options, warrants or convertible securities because the effect of their inclusion would be anti-dilutive. TGC's seismic crew experienced adverse weather conditions during the second quarter of 2002 and was unable to operate at sufficient production levels to maintain profitability. Because oil and gas exploration companies continue to curtail their domestic oil and gas exploration programs, there continues to be excess capacity in the land-based geophysical services industry and pricing remains very competitive. As a result, management continues to monitor expenses and, where possible, implement cost containment programs to remain highly competitive through this continued period of reduced industry activity. In the opinion of management, despite the need for more U.S. energy self- sufficiency and the industry having favorable longer-term prospects, there are not as yet clear indications of when the geophysical industry will show significant signs of improvement. During 2001 there were a number of consolidations and mergers in the geophysical industry. Management is hopeful that with fewer seismic crews available in the marketplace that TGC will be able to secure contracts with improved margins thereby continuing to improve its performance in 2002. Non-cash charges for depreciation and amortization were $772,038 in the first six months of 2002 compared with $806,252 for the same period of 2001. At December 31, 2001, TGC had net operating loss carryforwards of approximately $8,100,000 available to offset future taxable income, which expire at various dates through 2021. 9 As previously reported, TGC had been notified by Nasdaq of potential delisting of the Company's Common Stock from the Nasdaq SmallCap Market. TGC announced on May 20, 2002, that the Company had been notified by Nasdaq that, in accordance with Marketplace Rule 4310(c)(8)(B), the Company's securities were being delisted from Nasdaq SmallCap Market at the opening of Business on May 24, 2002, due to the Company's Common Stock, as previously reported, having failed to maintain a minimum market value of publicly held shares of $1,000,000 as required by Marketplace Rule 4310(c)(7). Also, as previously reported, following the delisting, the Company's securities now trade over- the-counter on the National Association of Securities Dealers, Inc. Over-The- Counter Bulletin Board System. FINANCIAL CONDITION Cash of $24,006 was provided by operations for the first six months of 2002 compared with cash provided by operations of $1,463,232 for the same period of 2001. This decrease in cash from operations in the first six months of 2002 was primarily the result of a decrease in billings in excess of cost and estimated earnings on uncompleted contracts and a decrease in accounts payable, partially offset by a decrease in accounts receivable, resulting from a decline in the level of activity during the first six months of 2002 as compared with the last three months of 2001. Net cash of $100,240 was used in investing activities during the first six months of 2002 for capital expenditures to replace certain vehicles and equipment. Principal payments of notes of $14,978, principal payments of capital lease obligations of $145,111 and proceeds from the issuance of debt of $29,861 resulted in net cash of $130,228 being used in financing activities during the first six months of 2002. TGC anticipates that available funds, together with anticipated cash flows generated from future operations will be sufficient to meet TGC's minimum lease and note payment obligations. Working capital increased $454,893 to $667,249 at June 30, 2002 from the December 31, 2001, working capital of $212,356. The Company's current ratio was 2.1 at June 30, 2002, compared with 1.1 at December 31, 2001. Stockholders' equity decreased $182,439 to $2,844,344 at June 30, 2002 from the December 31, 2001 balance of $3,026,783. This decrease was attributable to the net loss, before dividend requirements on preferred stock, of $182,439. Management believes adequate sources of financing are available to enable the Company to continue operations in the event operating revenue does not provide sufficient cash to fund the Company's existing and ongoing obligations. Forward-Looking Statements This report contains forward-looking statements which reflect the view of Company's management with respect to future events.
