BOLT TECHNOLOGY REPORTED THIRD QUARTER RESULTS.

NORWALK, CT., April 23, 2009 – Bolt Technology Corporation (NASDAQ: BOLT) today announced financial results for the third quarter and the first nine months of fiscal year 2009.

Sales for the third quarter of fiscal 2009, the three months ended March 31, 2009, amounted to $12,960,000 compared to $15,713,000 in last year’s third quarter. Income from continuing operations for the quarter amounted to $3,004,000 ($0.35 per share) compared to $3,219,000 ($0.38 per share) in last year’s third quarter, and net income for the quarter amounted to $3,004,000 ($0.35 per share) compared to $3,404,000 ($0.40 per share) in last year’s third quarter.

For the nine months ended March 31, 2009, sales amounted to $37,813,000 compared to $46,714,000 for the same period last year. Income from continuing operations for the nine months ended March 31, 2009 amounted to $8,310,000 ($0.97 per share) compared to $10,017,000 ($1.17 per share) for the same period last year, and net income for the period amounted to $8,310,000 ($0.97 per share) compared to $10,459,000 ($1.22 per share) for the same period last year.

Raymond M. Soto, Bolt’s Chairman, President and CEO, commented, “In the third quarter of fiscal year 2009 our sales deceased 18% compared to the third quarter of fiscal year 2008 and our income from continuing operations decreased 7% compared to last year’s third quarter. The decreases reflect lower shipments of energy source systems and controllers partially offset by higher shipments of energy source replacement parts and underwater cables and connectors.”

Mr. Soto added, “Although the continuing economic slowdown and lower commodity prices have reduced expenditures for marine seismic exploration, we believe, based on our year-to-date earnings and current level of customer inquiries and orders, that fiscal year 2009 will be a good year for our company.”

Bolt Technology Corporation is a leading worldwide developer and manufacturer of oilfield services equipment, including seismic energy sources, seismic source controllers and synchronizers and underwater cables and connectors used in offshore seismic exploration for oil and gas.
