Houston, Texas - December 10, 2010 - OYO Geospace (NASDAQ: OYOG) today announced net income of $14.1 million, or $2.27 per diluted share, on revenues of $128.5 million for its fiscal year ended September 30, 2010. This compares with a net income of $1.8 million, or $0.29 per diluted share, on revenues of $92.9 million for the prior fiscal year.

For the fourth quarter ended September 30, 2010, the company recorded sales of $36.1 million and net income of $5.1 million, or $0.82 per diluted share. For the comparable period last year the company recorded sales of $22.7 million and a net loss of $1.8 million, or $0.30 per diluted share.

Gary D. Owens, OYO Geospace's Chairman, President and CEO said, "Our fourth quarter revenues increased $13.4 million, or 59%, from last year's fourth quarter. The majority of this revenue increase was due to higher demand for our seismic reservoir, seismic marine and industrial products. For the fourth quarter, sales to our seismic reservoir customers increased $6.3 million from the fourth quarter of last year, primarily resulting from resumed demand for borehole systems and the previously announced $4.0 million contract with BP for additional seabed cables in the Valhall field. Sales of our seismic marine products in the fourth quarter increased $3.6 million from the comparable period in the prior year primarily due to unusually low demand in the prior year. Fourth quarter revenues from our industrial customers increased $2.2 million from the comparable period in the prior year due to the sale of a borehole system and a small GSR wireless data acquisition system. These particular sales transactions are rather unusual since our industrial customers are not expected to utilize these systems for oil and gas exploration activities. Sales of our GSR wireless data acquisition systems to seismic exploration customers decreased slightly from the fourth quarter of last year."

"Although the year started slowly, we saw sequential revenue increases during each quarter of fiscal year 2010. Almost all of our product categories contributed to the year-over-year increase in revenues, and we are particularly pleased with the sales momentum and continued customer interest in our GSR wireless data acquisition system. We are quoting several significant GSR rental opportunities which exceed our current rental fleet commitment of 15,000 channels. In order to accommodate this demand, we are increasing our GSR rental fleet to 30,000 channels. We expect to add these additional rental channels over the course of fiscal year 2011."

"Since September 30, 2010, the company has announced the receipt of several new orders from Dawson Geophysical and Tidelands Geophysical totaling 21,000 GSR channels. The Dawson Geophysical orders include 2,000 four-channel units and 10,000 single-channel units, together totaling 18,000 channels. We expect to deliver the Dawson Geophysical orders during the first and second quarters of fiscal year 2011. Upon delivery, Dawson Geophysical will own 26,000 GSR channels. The Tidelands Geophysical order was for 3,000 additional single-channel GSR units, and delivery is expected during the first quarter of fiscal year 2011. Upon delivery, Tidelands Geophysical will own 7,000 GSR channels."

"We finished fiscal year 2010 with $33.5 million of cash, an increase of $24.9 million since September 30, 2009. We also improved the management of our working capital and lowered our debt levels. Based on our product shipments to date, our current product backlog and high levels of quoting activity for GSR sales and rentals, as well as other product opportunities, we are optimistic about the immediate outlook for the first quarter of fiscal year 2011."
