See notes to Financial Statements TGC INDUSTRIES, INC. NOTES TO FINANCIAL STATEMENTS (UNAUDITED) September 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 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 per common share is based upon the weighted average number of shares of common stock outstanding. Diluted earnings 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 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 $5,536,737 for the three months ended September 30, 1998, from $4,166,333 for the same period of the prior year. Net income, before dividend requirements on preferred stock increased to $957,825, compared with net income, before dividend requirements on preferred stock, of $310,352 for the same period of the prior year. Income per common share, on a diluted basis, was $.07 for the third quarter of 1998, as compared with income of $.02 per common share for the same period of 1997. For the nine month period ended September 30, 1998, revenues increased to $15,376,804 from $11,647,356 for the same period of the prior year. Net income, for the first nine months of 1998, before dividend requirements on preferred stock, increased to $2,048,384, compared with net income, before dividend requirements on preferred stock, of $721,242 for the same period of the prior year. Income per common share, on a diluted basis, was $.14 for the first nine months of 1998, as compared with income of $.05 per common share for the same period of 1997. TGC's cost of services, as a percentage of revenue, were 76.5% for the third quarter of 1998, compared to 86.4% for the same period of 1997. Selling, general and administrative expense, as a percentage of revenue, was 5.2% for the third quarter of 1998 and 1997 respectively. Interest expense increased by $17,812 in the third 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 80% for the first nine months of 1998, compared to 86.9% for the same period of 1997. Selling, general and administrative expense, as a percentage of revenue, was 5.4% for the first nine months of 1998, compared to 5.8% for the same period of 1997. Interest expense increased by $69,558 in the first nine 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 $1,297,335 in the first nine months of 1998 compared with $929,798 for the same period of 1997. At December 31, 1997, TGC had net operating loss carryforwards of approximately $4,400,000 available to offset future taxable income, which expire at various dates through 2012. TGC operates two land seismic crews primarily conducting Three-D ("3-D") seismic surveys for clients in the oil and gas business. Oil and gas prices (principally oil prices) have declined significantly during 1998. As a result, related service industries have been negatively impacted. Many oil and gas exploration projects have been put on hold, canceled, or postponed until favorable prices return. The Company's nine month financial results are at record levels, but unsettled pricing conditions in the Oil and Gas Industry will negatively impact results for the fourth quarter of 1998 and are expected to continue into early 1999. FINANCIAL CONDITION Cash of $2,297,181 was provided from operations for the first nine months of 1998 compared with cash provided from operations of $1,213,674 for the same period of 1997. The funds generated in the first nine months of 1998 were primarily attributable to net earnings before non-cash depreciation charges. Cash used in investing activities for the first nine months of 1998 was primarily for the replacement of equipment in the amount of $385,289. Cash used in financing activities for the first nine months of 1998 was primarily for principal payments of debt obligations in the amount of $997,446, and dividend payments on preferred stock of $225,870. Working capital deficit decreased $1,640,126 to $607,761 from the December 31, 1997 balance of $2,247,887. The Company's current ratio was .76 to 1.0 at September 30, 1998, compared with .57 to 1.0 at December 31, 1997. Stockholders equity increased $1,840,514 from the December 31, 1997 balance of $3,729,993 to $5,570,507 at September 30, 1998. This increase was primarily attributable to net income for the nine months ended September 30, 1998, of $2,048,384. 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 is working to resolve the potential impact of the year 2000 on the ability of the Company's computerized information systems to accurately process information that may be date-sensitive. The Company utilizes a number of computer programs across its entire operation. None of these computer programs have been custom written for the Company. The Company is completing its assessment, but currently believes that costs of addressing this issue will not have a material adverse impact on the Company's financial position. 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. The Company has been notified by Nasdaq of potential delisting of the Company's Common Stock due to having failed to equal or exceed the minimum bid price requirement of $1.00 per share for thirty consecutive trading days. The Company, as a condition to continued listing of its securities on the SmallCap Market, must satisfy the minimum bid price requirement. On September 3, 1998, the Company filed a Proxy Statement with the Securities and Exchange Commission with respect to a special meeting of its shareholders to be held on November 5, 1998, to approve a 1-for-3 reverse stock split of the Company's Common Stock. The record date for the special meeting was September 22, 1998, and the Proxy Statements were mailed to shareholders on September 24, 1998. The Company is confident that the shareholders will approve the 1-for-3 reverse stock split of its Common Stock. The Company's Board of Directors believes that the reverse stock split, which will cause the price of the Common Stock to increase, will satisfy the minimum bid price requirement. On October 26, 1998, Nasdaq informed the Company of the determination of the Nasdaq Listing Qualifications Panel following a written hearing on October 23, 1998, to continue the listing of the Company's securities provided that the Company effect its 1-for-3 reverse stock split on or before November 11, 1998, and thereafter evidence a closing bid price for its Common Stock that meets or exceeds $1.00 per share for a minimum of ten consecutive trading days. The Company believes that it can meet these conditions. As stated above, the Company is confident that the shareholders will approve the 1-for-3 reverse stock split of its Common Stock at the special meeting on November 5, 1998, and the Company intends to effect the reverse stock split effective with the close of business on Friday, November 6, 1998, and for the Common Stock to commence trading on a post-reverse split basis on Monday, November 9, 1998. 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.
