EARNINGS RELEASEFor Immediate ReleaseContact: Raymond M. Soto (203) 853-0700BOLT TECHNOLOGY REPORTS FOURTH QUARTER AND FISCAL 2011 RESULTS

NORWALK, CT., August 18, 2011 – Bolt Technology Corporation (NASDAQ Global Select Market: BOLT) today announced financial results for the fourth quarter and the fiscal year ended June 30, 2011.

Sales for the fourth quarter of fiscal year 2011, the three months ended June 30, 2011, were $10,819,000 compared to $9,880,000 for the fourth quarter of fiscal year 2010. Net income for the quarter was $1,386,000 ($0.16 per share) compared to $1,634,000 ($0.19 per share) for the fourth quarter of fiscal year 2010.

For the fiscal year ended June 30, 2011, sales amounted to $38,858,000 compared to

$31,485,000 last fiscal year. Net income for the year amounted to $5,527,000 ($0.65 per

share) compared to $4,954,000 ($0.58 per share) last year.

Raymond M. Soto, Bolt’s chairman, president and CEO, commented, “I am pleased to report that our sales and net income in fiscal year 2011 increased by 23% and 12%, respectively, over fiscal year 2010. We have a strong balance sheet at June 30, 2011 including almost $32,000,000 in cash, after completing substantial investing activities during the year, including the acquisition of SeaBotix Inc. and repurchases of our stock. In addition, our Company remains debt free.”

Mr. Soto further commented, “Our marine seismic data acquisition equipment segments operated profitably in the fourth quarter and for fiscal year 2011. Sales and net income for these segments increased by 15% and 21%, respectively, over last year due to improved marine seismic exploration activity. As previously reported, effective January

1, 2011 our Company acquired SeaBotix Inc., a manufacturer and developer of

underwater robotic vehicles. SeaBotix reported sales of $2,575,000 and a net loss of

$462,000 for the six month period ended June 30, 2011. These results were

disappointing, and reflect recent budgetary pressure within local, state and national governmental units that comprise SeaBotix’s major customer groups. SeaBotix’s sales did increase from $895,000 in the third quarter to $1,680,000 in the fourth quarter of fiscal year 2011.”

Mr. Soto continued, “The Company is cautiously optimistic that improved sales and net income for our marine seismic data acquisition equipment segments will continue in fiscal year 2012. This is dependent, however, on sustained global economic growth and minimal long term impact of the Deepwater Horizon incident in the Gulf of Mexico. The

Company is also hopeful that the improvement in SeaBotix’s sales in the fourth quarter of fiscal year 2011 will continue into fiscal year 2012. Any such improvement is also dependent on sustained global economic growth, as well as improved budgetary conditions at their major customer groups and acceptance in the marketplace of the new SeaBotix underwater robotic products.”

Bolt Technology Corporation is a leading worldwide developer and manufacturer of marine seismic data acquisition equipment used for offshore oil and natural gas exploration. Bolt, through its SeaBotix Inc. subsidiary, is also a developer and manufacturer of remotely-operated robotic vehicles systems used for a variety of underwater tasks. The Company’s operating segments include “Seismic Energy Sources,” “Underwater Cables and Connectors,” “Seismic Energy Source Controllers” and “Underwater Robotic Vehicles.”
