Houston, Texas - December 9, 2011 - OYO Geospace (NASDAQ: OYOG) today announced net income of $29.7 million, or $4.73 per diluted share, on revenues of $173.0 million for its fiscal year ended September 30, 2011. This compares with a net income of $14.1 million, or $2.27 per diluted share, on revenues of $128.5 million for the prior fiscal year.

For the fourth quarter ended September 30, 2011, the company recorded revenues of $32.8 million and net income of $3.6 million, or $0.56 per diluted share. For the comparable period last year the company recorded revenues of $36.1 million and a net income of $5.1 million, or $0.82 per diluted share.

"We are proud of our financial results for fiscal year 2011, setting records for revenues and profits significantly higher than any previous fiscal year. Our revenues grew by 35% over fiscal year 2010 levels and our net income increased by 111%. While almost all of our key products contributed to this growth, sales and rentals of our GSR wireless data acquisition systems generated record revenues in fiscal year 2011. Our customers are currently utilizing these wireless systems in North and South America, Europe, the Middle East, Africa, India, Australia and Japan. We expanded our rental operations in fiscal year 2011 by establishing a significant fleet of GSR wireless channels. We were able to get these rental systems in the hands of new customers while also broadening the size of wireless crews for our existing customer base. Since its introduction in fiscal year 2008 and through September 30, 2011, we have sold approximately 85,000 GSR wireless channels and at September 30, 2011 we had approximately 20,000 GSR wireless channels in our rental fleet available for rent to our customers. Furthermore, we again saw growth in demand for our borehole products and for most of our traditional seismic products in fiscal year 2011. By any measure, fiscal year 2011 was outstanding," said Gary D. Owens, the company's Chairman, President and CEO.

"After three consecutive record quarters of profitability in fiscal year 2011, we saw a brief respite in the scheduled shipments of our seismic products during the fourth quarter. However, we did deliver over 6,000 GSR wireless channels to four different customers, including two new customers. As we have observed over the years, we have experienced substantial variations in our results from quarter to quarter. Although the sales and profits in the quarter were lower than expected, our backlog remains healthy for our seismic products and we expect higher levels of shipments in the first quarter of fiscal year 2012."

"In the first quarter of fiscal year 2012 ending on December 31, 2011, we expect to ship at least 12,000 GSR wireless channels including the recently announced GSR system to Breckenridge Exploration. This $7.4 million order from Breckenridge, which includes 5,000 GSR channels and other seismic equipment, represents another new customer for our GSR wireless product line. As we enter fiscal year 2012, we are seeing opportunities to add up to 40,000 additional wireless channels to our rental fleet, including over 10,000 3-channel wireless stations, for our customers working in the Marcellus shale, Canadian and other international seismic markets. Furthermore, we expect strong shipments of our borehole products during the first quarter of fiscal year 2012. These orders and good levels of backlog for our traditional products should get us off to a strong start for the new fiscal year."

"We finished fiscal year 2011 with $36.3 million of cash/short-term investments and no long-term debt in spite of significant investments into our inventories and expansion of our rental equipment fleet. The increase in business activity in fiscal year 2011 and our strong order backlog going into fiscal year 2012 led to the hiring of more than 100 new employees during fiscal year 2011, and we expect to add more new employees in the coming months. We believe that the company is well-positioned for any new opportunities ahead."

"The company's increasing growth has required us to expand our management ranks. It is with great pleasure that I announce the appointment by the company's Board of Directors of two new senior officers effective January 1, 2012."
