BOLT TECHNOLOGY REPORTS FIRST QUARTER RESULTS WHICH INCLUDE RECORD QUARTERLY SALES

NORWALK, CT., October 25, 2005 – Bolt Technology Corporation (AMEX:BTJ) today announced financial results for the first quarter of fiscal year 2006, the three months ended September 30, 2005.

Sales for the first quarter of fiscal 2006 increased 108% to $7,994,000 compared to $3,839,000 in last year’s first quarter and net income increased 383% to $1,020,000 or $0.18 per share compared to $211,000 or $0.04 per share last year.

Raymond M. Soto, Bolt’s chairman, president and CEO, commented, “I am pleased to report that our sales of $7,994,000 in the first quarter of fiscal 2006 are the highest quarterly sales ever recorded by our Company. Additionally, our first quarter income before income taxes of $1,610,000 is the highest quarterly income before taxes reported by our Company during the last twenty-two years. The first quarter results reflect the continuing strengthening of the marine seismic market and a $2,000,000 sale of our second system of Annular Port Guns (“APG”).

Mr. Soto added, “We expect the marine seismic market to remain strong as world oil producers continue to increase their exploration, development and production activity to meet global demand for energy. We remain cautiously optimistic that the remainder of fiscal 2006 will continue to show improved results compared to last year. In this regard, we are pleased to report we have recently received two major orders for marine seismic energy source systems which total over $3,600,000. One of these orders is for another APG system, and both orders are scheduled for shipment in the fourth quarter.”

Bolt Technology Corporation is a leading worldwide developer and manufacturer of seismic energy sources and underwater connectors used in offshore seismic exploration for oil and gas. Bolt also designs, manufactures and sells precision miniature industrial clutches, brakes and electric motors.
