EXHIBIT 99 IDX Systems Corporation 1400 Shelburne Road Burlington, VT 05402-1070 - -------------------------------------------------------------------------------- Contact: Jack Kane Chief Financial Officer (802) 864-1758 x6199 FOR IMMEDIATE RELEASE IDX SYSTEMS CORPORATION ANNOUNCES PRELIMINARY FIRST QUARTER RESULTS BURLINGTON, VT, March 5, 1999 -- IDX Systems Corporation (Nasdaq: IDXC) announced today that based on currently available information, the Company expects sales for the first quarter ending March 31, 1999 to be in the range of $60 to $65 million. Sales in this range are expected to result in a loss of ($0.22) - ($0.28) per share for the quarter, versus analysts' consensus estimates of $.35 per share. The after tax loss for the quarter is expected to be ($5) - ($7) million. "We believe the primary factor in the sales shortfall is the unexpected deferral of purchasing decisions by our customers and prospects," said Richard E. Tarrant, IDX Chief Executive Officer. "Although our projected first quarter performance is well below expectation, we believe that our business is fundamentally sound. Based on the information available, we expect to return to profitability in the second quarter. The contracts that have been delayed are still in the pipeline. IDX has a well-established customer base, a proven track record and functionally rich, integrated products and services. We are committed to a strategy of combining enterprise software with the advantages of Internet technology, which positions the Company for future growth."
