GEOSPACE TECHNOLOGIES REPORTS FISCAL YEAR 2013

SECOND QUARTER RESULTS AND OTHER RECENT MATTERS

Houston, Texas - May 2, 2013 - Geospace Technologies Corporation (NASDAQ: GEOS) today announced net income of $16.9 million, or $1.30 per diluted share, on revenues of $76.4 million for its fiscal quarter ended March 31, 2013. This compares with a net income of $11.4 million, or $0.89 per diluted share, on revenues of $56.2 million for the comparable quarter last year.

For the six months ended March 31, 2013, Geospace recorded revenues of $154.2 million and net income of $38.9 million, or $3.01 per diluted share. For the comparable period last year, the company recorded revenues of $99.5 million and net income of $20.1 million, or $1.57 per diluted share.

"The quarter ended March 31, 2013 was the second most profitable quarter in our company's history, with revenues and net income up 36% and 48%, respectively, from last year's second quarter. While we are pleased with our performance, these quarterly results were affected by a decrease in our wireless product revenues which declined from $21.5 million in last year's second quarter to $15.7 million for the quarter ended March 31, 2013. Rentals of our wireless products during the second quarter ended March 31, 2013 increased over the prior year. As we have stated many times, orders and deliveries of our products can be inconsistent from quarter-to-quarter and this was especially true for our first and second quarters of fiscal year 2013. We are actively quoting new sales and rentals of our wireless products and we believe that customer interest in these products remains high. However, due to the unpredictability of the timing of such orders and our inability to control delivery terms, we expect sales of our wireless products to continue to be lumpy in future quarters," said Gary D. Owens, Geospace Technologies' Chairman, President and CEO.

"For the second quarter ended March 31, 2013, we sold approximately 13,000 channels of our wireless data acquisition system including small system sales to three new customers located in Mexico, Russia and Indonesia. A fourth customer operating in Poland significantly expanded their wireless channel ownership during the second quarter. These sales transactions reflect our strategy to place our wireless technology into international markets. Since its introduction back in 2008 and through March 31, 2013, we sold approximately 218,000 wireless channels and we had 77,000 wireless channels in our worldwide rental fleet."

"During the second quarter, we sold a small OBX subsea nodal system to a Russian customer. In addition, we shipped two small OBX rental systems during the second quarter. Interest in our OBX system remains high with numerous outstanding quotes, including several quotes of a significant size. While we are optimistic about our marine nodal technology, we cannot predict whether these quotes will ultimately result in firm orders or when such orders may occur."

"During the second quarter we recognized revenue of approximately $21.0 million from the $160 million Statoil order using the percentage of completion method of accounting. We have revised our previous estimate whereby we now believe that approximately 45% and 55% of the Statoil order's revenues and costs will be recognized in fiscal years 2013 and 2014, respectively. In addition, we shipped a majority of the components for Shell's permanent seabed seismic reservoir monitoring system resulting in $17.1 million of revenues during the second quarter. The remaining portion of the Shell order totaling $1.2 million is expected to be shipped in the third quarter."

"While our traditional seismic product sales for the second quarter were generally flat compared to the first quarter of fiscal year 2013, sales for this product group declined 37.5% from last year's second quarter. Marine products, sensor products and geophone rentals each contributed to this decline in sales. It should be noted that we experienced robust marine product sales during the second quarter of fiscal year 2012, and sales of our marine products also can fluctuate significantly from quarter to quarter. Despite revenue declines in these product categories, our Russian and Canadian operations experienced improved sales and profits during the second quarter when compared to last year. We are proud to note that our Russian operation completed its first wireless equipment rental during the second quarter. Also during the second quarter, our new office in Bogotá, Colombia celebrated its grand opening and completed its first rental transaction. We believe this foothold in South America will be beneficial for the company."

"We recently entered into an agreement to purchase a 9.6 acre plot of land that adjoins the southern boundary of our Pinemont property in Houston. Upon completion of this transaction, which is currently scheduled to close next week, our Pinemont property will contain approximately 29 acres of land. Over the course of the next two years, we plan to construct significant additional plant capacity on our Pinemont property to enlarge our cabling, machining, molding and assembly areas. In addition, we plan to expand our research and development facilities to accommodate growth in this important area. We will provide future updates on expected timing of construction activities, estimated range of capital investment and other information as it becomes available."

In a separate matter, the company is pleased to announce that Mr. Richard F. Miles, a well-known and highly experienced seismic industry executive, has joined our board of directors to fill a vacancy.

Geospace Technologies Corporation designs and manufactures instruments and equipment used by the oil and gas industry in the acquisition and processing of seismic data as well as in reservoir characterization and monitoring activities. The company also designs and manufactures non-seismic products, including industrial products, offshore cables, thermal printing equipment and film.
