Evans & Sutherland Reports First Quarter 2005 Results

SALT LAKE CITY, UTAH, April 21, 2005—Evans & Sutherland Computer Corporation (NASDAQ: ESCC) today reported financial results for the first quarter ended April 1, 2005.

Sales for the first quarter were $13.9 million, down 22.1% from sales of $17.8 million in the first quarter of 2004.  Net loss was $6.0 million, or $0.57 per share, compared to a net loss of $3.0 million, or $0.29 per share, in 2004.

Comments from James R. Oyler, President and Chief Executive Officer

“The first quarter of 2005 was seasonally weak as expected.  In addition, we had significant restructuring expenses in the first quarter that will lead to lower operating expenses for the remainder of the year.  Our net cash reached the highest level in five years, and backlog was nearly unchanged and remains at the highest level in three years.  The combination of high backlog and reduced operating expenses after the restructuring will drive improved results for the remainder of the year.

“We experienced high research and development expenses during the quarter as we continue to prepare the Evans & Sutherland Laser Projector (ESLP) for commercial shipments beginning in the third quarter of this year.  R&D expenses will decline as the ESLP enters production.

“Based on our continued strong backlog and lower expenses in future quarters, our overall outlook for a small profit for the year remains unchanged.”
