RESULTS OF OPERATIONS AND FINANCIAL CONDITION. On July 24, 2003, VASCO Data Security International, Inc. ("VASCO") issued a press release updating the previously released financial update for the second quarter ended June 30, 2003. The full text of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K. On July 24, 2003, VASCO held a conference call with investors to discuss VASCO's second quarter earnings and results of operations for the first six months of 2003. A script read by officers of VASCO during the conference call is furnished as Exhibit 99.2 to this Current Report on Form 8-K. The press release contains a reference to EBITDA and provides a reconciliation of EBITDA to net income (loss) on the face of the Consolidated Statement of Operations. EBITDA is used by management for comparisons to other companies within our industry as an alternative to GAAP measures and is used by investors and analysts in evaluating performance. EBITDA, which is earnings before interest, taxes, depreciation and amortization, is computed by adding back net interest expense, income tax expense, depreciation expense, and amortization expense to net income as reported. EBITDA should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with accounting principles generally accepted in the United States. EBITDA, as defined above, may not be comparable to similarly titled measures reported by other companies. 2 SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
