Houston, Texas - August 5, 2011 - OYO Geospace (NASDAQ: OYOG) today announced net income of $9.2 million, or $1.44 per diluted share, on revenues of $46.4 million for its quarter ended June 30, 2011. This compares with a net income of $5.1 million, or $0.81 per diluted share, on revenues of $35.3 million in the comparable quarter last year.

For the nine months ended June 30, 2011, OYO Geospace recorded sales of $140.2 million and net income of $26.1 million, or $4.15 per diluted share. For the comparable period last year the company recorded sales of $92.4 million and net income of $9.0 million, or $1.45 per diluted share.

"We are pleased with our results for the third quarter ended June 30, 2011, establishing new records for net income and earnings per share for the third consecutive quarter. Revenues for the third quarter were 31.4% higher than last year's third quarter, and 51.7% higher for the nine months ended June 30, 2011. Our customers are reporting increased demand and improved pricing for their services which gives us confidence that demand for our products will remain high in the near term. However, while we have experienced strong operating results over the last year, we are uncertain how current worldwide economic matters will potentially impact our business in the future," said Gary D. Owens, OYO Geospace's Chairman, President and CEO.

"For the quarter ended June 30, 2011, demand was strong across almost all product categories and geographical markets. Revenues from our seismic exploration products were 44.0% higher than last year's third quarter, including particularly strong demand for our GSR wireless data acquisition system and marine products. While we experienced average levels of revenues from our borehole products during the third quarter, revenues on a year-to-date basis are 107.6% ahead of last year. Our industrial and thermal product revenues outpaced our prior year results for both the quarter and year-to-date periods."

"In early July, we announced a $15.6 million sale to Dawson Geophysical Company in the third quarter for 14,850 channels of our GSR wireless data acquisition system and related equipment. Dawson was renting this equipment prior to the purchase transaction. This transaction was significant to our third quarter results, and affirms our strategy of making the GSR technology available to our customers under a variety of options to fit their capital needs, including short-term rentals, equipment financing or traditional purchases. During the quarter, we also sold a 1,000-channel GSR system to a new customer working in Morocco and another small 400-channel GSR system to an existing customer in Japan. At June 30, 2011, our customers owned over 78,000 GSR channels, and our rental fleet was reduced to almost 13,000 GSR channels. Subsequent to the end of our third quarter, we sold a 5,000-channel GSR system to TGC Industries. We are attending to other GSR quotations for both sales and rentals, and our GSR demonstrations continue in oil and gas exploration regions around the globe."

"During the quarter we made shipments to two new customers for our borehole seismic systems, including our first seismic borehole system sale in China for well fracture-monitoring applications. This system will be utilized to monitor well-fracturing activities in an unconventional shale play in the western part of China. We believe the Chinese market holds very good potential for our seismic borehole products as China begins to develop its domestic natural gas resources."
