TGC INDUSTRIES, INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) June 30, 1998 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 generally accepted accounting principles. 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, 1997 filed on Form 10-KSB. NOTE C -- EARNINGS (LOSS) PER SHARE During December 1997, the Company adopted Statement of Financial Accounting Standards No. 128 (SFAS 128), "Earnings Per Share." Under SFAS 128, basic earnings (loss) per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings (loss) per share is based upon the weighted average number of common shares outstanding and, when dilutive, common shares issuable for stock options, warrants and convertible securities. Earnings (loss) per share data for 1997 has been restated to conform to the provisions of SFAS 128. ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. RESULTS OF OPERATIONS TGC Industries, Inc. ("TGC") reported revenues increased to $5,520,738 for the three months ended June 30, 1998, from $4,740,670 for the same period of the prior year. Net income, before dividend requirements on preferred stock increased to $875,036, compared with net income, before dividend requirements on preferred stock, of $450,742 for the same period of the prior year. Income per common share, on a diluted basis, was $.06 for the second quarter of 1998, as compared with income of $.03 per common share for the same period of 1997. For the six month period ended June 30, 1998, revenues increased to $9,840,067 from $7,481,023 for the same period of the prior year. Net income, for the first six months of 1998, before dividend requirements on preferred stock, increased to $1,090,559, compared with net income, before dividend requirements on preferred stock, of $410,890 for the same period the prior year. Income per common share, on a diluted basis, was $.08 for the first six months of 1998, as compared with income of $.03 per common share for the same period of 1997. TGC's cost of services, as a percentage of revenue, were 77.8% for the second quarter of 1998, compared to 84.3% for the same period of 1997. Selling, general and administrative expense, as a percentage of revenue, was 5.2% for the second quarter of 1998 and 1997, respectively. Interest expense increased by $25,421 in the second quarter of 1998 when compared with the same period of 1997. This increase was primarily a result of the financing of additional geophysical equipment in the second half of 1997. TGC's cost of services, as a percentage of revenue, were 82% for the first six months of 1998, compared to 87.2% for the same period of 1997. Selling, general and administrative expense, as a percentage of revenue, was 5.5% for the first six months of 1998, compared to 6.1% for the same period of the 1997. Interest expense increased by $51,746 in the first six months of 1998, when compared with the same period of the prior year. This increase was principally attributable to the financing of additional geophysical equipment in the second half of 1997. Non-cash charges for depreciation were $841,636 in the first six months of 1998 compared with $596,815 for the same period of 1997. TGC operates two land seismic crews primarily conducting Three-D ("3-D") data gathering for clients in the oil and gas business. If the 1998 exploration budgets of oil and gas companies are reduced significantly due to the reduction in oil prices, TGC's revenues and earnings may be adversely affected. TGC announced a recent purchase of the latest technologies in central recording units from Sercel Inc. to enhance seismic recording capabilities. This equipment will up- grade one of TGC's existing crews enabling the crew to acquire 3-D surveys more efficiently. In addition, TGC will be entering the shot hole drilling business with the initial purchase of three drilling rigs. With these rigs, TGC will reduce costs and its dependence on third-party drilling contractors. With the addition of this equipment, TGC will be better positioned to service our clients on their future contracts. TGC will finance this purchase using internal cash flow and equipment financing. This report contains forward-looking statements which reflect the view of Company's management with respect to future events. 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, without limitation, the unpredictable nature of forecasting weather, the potential for contract delay or cancellation, and the potential for fluctuations in oil and gas prices. 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. FINANCIAL CONDITION Cash of $2,121,169 was provided from operations for the first six months of 1998 compared with cash provided from operations of $766,746 for the same period of 1997. The funds generated in the first six months of 1998 were primarily attributable to net earnings before non-cash depreciation charges. Cash used in investing activities for the first six months of 1998 was primarily for the replacement of equipment in the amount of $291,711. Cash used in financing activities for the first six months of 1998 was primarily for principal payments of debt obligations in the amount of $646,756, and dividend payments on preferred stock of $225,870. Working capital deficit decreased $828,352 to $1,419,535 from the December 31, 1997 balance of $2,247,887. The Company's current ratio was .67 to 1.0 at June 30, 1998, compared with .57 to 1.0 at December 31, 1997. Stockholders equity increased $881,564 from the December 31, 1997 balance of $3,729,993 to $4,611,557 at June 30, 1998. This increase was primarily attributable to net income for the six months ended June 30, 1998, of $1,090,559. During the fourth quarter of 1997, to support future growth of the Company, a $1,000,000 revolving bank line of credit was secured from a major bank. The line of credit bears interest at prime plus 1.5%, is collateralized by equipment and accounts receivable and requires the maintenance of certain financial ratios. The Company anticipates that available funds, together with anticipated cash flows generated from future operations and amounts available under its revolving line of credit will be sufficient to meet the Company's cash needs during 1998.
