FOR IMMEDIATE RELEASE

GEOSPACE TECHNOLOGIES REPORTS FISCAL YEAR 2014

SECOND QUARTER RESULTS

Houston, Texas – May 7, 2014 – Geospace Technologies (NASDAQ: GEOS) today announced net income of $10.8 million, or $0.82 per diluted share, on revenues of $68.6 million for its fiscal quarter ended March 31, 2014. This compares with a net income of $16.9 million, or $1.30 per diluted share, on revenues of $76.4 million for the comparable quarter last year.

For the six months ended March 31, 2014, the company recorded revenues of $169.9 million and net income of $35.0 million, or $2.66 per diluted share. For the comparable period last year, the company recorded revenues of $154.2 million and a net income of $38.9 million, or $3.01 per diluted share.

Walter R. Wheeler, Geospace Technologies’ President and CEO said, “Revenues and net income for the second quarter of our fiscal year saw respective reductions of 10% and 36% compared to the second quarter of last year. The lower quarterly revenues reflect reduced demand and deliveries for each of our product segments during the quarter. Lower product demand in our traditional and wireless product segments can be largely attributed to continued softness in the land seismic market, particularly in North America.”

“Sales of our traditional products declined sequentially from the first quarter and from last year due to a reduction in geophone sales, which often accompany large orders for our wireless data acquisition systems. Partially offsetting this decrease in sales was an increase in demand for our marine products. We expect demand for our other traditional products to remain soft for the remainder of the fiscal year.”

“GSX product sales were significantly lower than expected and were mostly comprised of low margin replacement parts and battery upgrades, with relatively few new channels sold during the quarter. Offsetting this low sales activity was a record quarter from our GSX rental operations. We are pleased to report that approximately 100,000 GSX channels were rented at March 31, 2014, helping us generate record rental revenues for the second quarter. The rental revenue contribution and channel utilization would have been better had our customers not experienced startup delays in both the Canadian and South American markets. We are pleased with the expanding utilization of our GSX products in North and South America and in Eastern Europe, and we look forward to increased opportunities developing new customer relationships in these and other regions. Since its inception and through March 31, 2014, we have sold 316,000 GSX channels and we had 133,000 GSX channels in our worldwide rental fleet.”

“We have recently executed several OBX rental contracts, with indications that marketplace demand is continuing to increase for this important new technology. We expect OBX rental demand will grow in future periods due to the short-term duration of many offshore projects and the risk perceived by some customers of unutilized time between jobs. Regarding the Seafloor Geophysical Solutions (“SGS”) matter, as we reported in March, SGS advised us that a portion of its earlier capital commitment had been withdrawn by a shareholder. Prior to that, SGS had placed a $29.4 million order with us, secured with a $3.3 million non-refundable deposit, for over 2300 stations of our deep-water OBX system. This system was scheduled to be delivered sometime in the third quarter ending June 30, 2014. The SGS management team reports that they are confident and underway with the process of arranging new investor funding, but we are unclear when this might conclude or if SGS will be successful in their capital-raising efforts. Until SGS successfully raises the additional funding, we cannot estimate when the equipment might be delivered, and as a result, delivery in the third quarter is at best uncertain and may not occur.”

“This second quarter essentially brought the large Statoil order to near completion, with only $5.3 million of revenues remaining to fulfill the contract. While our leading expertise in permanent reservoir monitoring (PRM) systems is already well known and established throughout the industry, our wealth of knowledge in this domain has expanded significantly through our development of these systems for Statoil’s Grane and Snorre fields. Once installed, these systems will mark history as the largest undertaking for reliable permanent reservoir monitoring ever accomplished, and we are privileged to have played an instrumental role with Statoil in this record breaking achievement. In another first, this quarter saw the delivery of a $5.0 million permanent land data acquisition system to Makamin Petroleum Services for installation and use in Saudi Arabia. This system is the first of its kind and we are pleased to be working with Makamin on this pioneering endeavor. Continuing with firsts, we delivered $4.4 million of additional equipment to BP to enlarge its PRM system installed at the Valhall field in the North Sea. The Valhall PRM system, designed and developed by Geospace and installed by BP in 2003, was the world’s first PRM system. With the pending completion of the Statoil contract, we expect revenues from our reservoir seismic products to decline significantly for the remainder of fiscal year 2014. However, we believe opportunities for new PRM systems will remain strong over the long term.”

“With work on the Statoil contract essentially completed, we have recently reduced our workforce at our Houston facility. However, we continue operating from three satellite locations in addition to our primary facilities on Pinemont Drive. In order to manage costs and efficiencies, we continue to believe it necessary to combine these satellite operations into our main Pinemont campus. This, combined with the need to accommodate future growth and to prepare and maintain our ability to take on large projects similar to the recently completed Statoil contract, we continue to pursue our plans of constructing a new building at our Pinemont location. While there have been some delays, the platting of our extended property is now complete, and designs for the new building are underway. Under these present circumstances, it looks like the earliest that construction permitting may begin would be sometime in June. This means that the earliest construction completion date is approximately March of 2015.”
