Stafford, Texas - November 12, 2001 - OYO Geospace Corporation (NASDAQ: OYOG) today announced sales of $63.6 million and net income of $1.3 million, or $0.24 per diluted share, for its fiscal year ended September 30, 2001. This compares with sales of $53.5 million and a net loss of $1.2 million, or $(0.22) per diluted share, for the prior year. The company said that its Fiscal 2001 sales primarily reflected increased activity in Canada as well as strengthening of its marine sales prior to mid-year declines in oil and gas prices.

For the fourth quarter, the company recorded sales of $15.9 million and a net loss of ($118,000), or $(0.02) per diluted share, as compared to sales of $12.8 million and a net loss of ($397,000), or $(0.07) per diluted share in the fourth quarter of the prior year. The company's fourth quarter results primarily reflect a deceleration in customer demand from earlier quarters in response to lower energy prices. Also, results were negatively affected by stalled orders and shipments as well as the company's inability to perform services stemming from business and travel interruptions associated with the United States' recent national tragedy.

"While we are pleased with the year-over-year improvement in our results, it appears that Fiscal 2002 will again be challenging for our traditional seismic product lines as declining natural gas and oil prices weakened the market for conventional seismic equipment business levels in the latter months of Fiscal 2001," said Gary D. Owens, OYO Geospace's Chairman.

"While commodity prices and international affairs are expected to dominate near-term results, our new reservoir characterization technology is poised to contribute significantly in the second half of Fiscal 2002. Our focus for this fiscal year remains unchanged. We remain committed to developing new products for new markets while continuing to improve our competitive position. Toward that end, we are continuing to reduce production costs, broaden production capabilities and increase our market scope both domestically and internationally," Owens said.

"In that regard, in November we restructured the company's participation in a Russian joint venture formed more than ten years ago with Geophyspribor Ufa Production Association and Chori Co Ltd. As part of the restructuring, OYO Geospace increased its equity ownership from 44% to 85% without further cash investment. The future operating results of the reorganized entity, now known as OYO-GEO Impulse International Ltd. LLC, will be consolidated with those of OYO Geospace," said Owens.

Based in Ufa, Bashkortostan, Russia since 1990, OYO-GEO Impulse has manufactured sensors for the Russian seismic marketplace with recent annual revenues in excess of $3.0 million. Under the new operating structure, the company's seismic manufacturing subsidiary in Houston will oversee an expansion of OYO-GEO Impulse's operations to produce international-standard sensors and additional products that will broaden its market scope. Geophyspribor Ufa Production Association and Chori Co., Ltd. will continue as minority shareholders of the new entity.

"Although affected by recent business and travel interruptions due to the national tragedy, we believe our commercial graphics products and new marketing strategies will continue to improve our performance in this segment of our business in Fiscal 2002," said Owens. "We are continuing to strengthen our operations in this area and will expand its scope during the next fiscal year."

OYO Geospace designs and manufactures instruments and equipment used in the acquisition and processing of seismic data for the oil and gas industry and for the commercial graphics industry worldwide.

STAFFORD, Texas - July 30, 2001 - OYO Geospace (NASDAQ: OYOG) today announced sales of $15.8 million and net income of $628,000, or $0.11 per diluted share, for its third quarter ended June 30, 2001. This compares with sales of $12.9 million and a net loss of $1.6 million, or $(0.30) per diluted share, in the comparable quarter of the prior year.

For the nine months ended June 30, 2001, OYO Geospace recorded sales of $47.7 million and net income of $1.5 million, or $0.26 per diluted share. This compares with sales of $40.7 million and a net loss of $794,000, or $(0.15) per diluted share, for the comparable period last year.

The company noted that its results for the quarter and year-to-date periods included a tax benefit of $188,000 and $207,000, respectively, due to the resolution of contingent tax matters.

"Our quarter-to-quarter and nine month comparisons reflect an improvement in seismic markets from the depressed levels of a year ago," said Gary D. Owens, OYO Geospace's Chairman. "Yet, while demand for seismic equipment has increased, it continues to be relatively lackluster, reflecting specific regional requirements rather than a sustained growth in overall demand."

"For OYO Geospace, one noteworthy aspect of this quarter was a healthy surge in demand for peripheral marine seismic devices," Owens said. "Demand for marine equipment, which has been virtually nonexistent over the past two years, picked up a bit this summer, driven by increased marine seismic activity."

"Visibility for future demand of our current products and services remains limited and difficult to predict. However, testing of our new technologies is proceeding well. We expect that these innovative products and services will contribute to our future growth," Owens continued.

OYO Geospace designs and manufactures instruments and equipment used in the acquisition and processing of seismic data for the oil and gas industry and for the commercial graphics industry worldwide.

STAFFORD, Texas - April 30, 2001 - OYO Geospace Corporation (NASDAQ: OYOG) today announced sales of $16.9 million and net income of $557,000, or $0.10 per diluted share, for its second quarter ended March 31, 2001. This compares with sales of $15.0 million and net income of $409,000, or $0.07 per diluted share, in last year's second quarter.

For the six months ended March 31, 2001, OYO Geospace recorded sales of $31.9 million, up 15% from $27.8 million in the prior year. Earnings for both the six-month period ended March 31, 2001 and the comparable period in 2000 were $828,000, or $0.15 per diluted share.

"We are very pleased with the quarter and believe that the market for geophysical products is strengthening," said Gary D. Owens, OYO Geospace's Chairman. "Not only did we experience increased demand for our geophysical products from Canada, but we also received orders from previously less active regions of the world. In our commercial graphics operations we experienced impressive growth in film sales, largely as a result of new strategies and our recent acquisition of EcoPRO, which partially offset a slowdown in equipment sales. We now see tremendous opportunities for expansion in this marketplace," Owens said.

"In addition, we are on track with the commercialization of our reservoir characterization and monitoring equipment and development of related services," said Owens.
