AND NINE-MONTH 2025 EARNINGS

Houston, Texas – August 7, 2025 – Geospace Technologies Corporation (NASDAQ: GEOS) (“the “Company") today announced results for its third quarter ended June 30, 2025. For the three-months ended June 30, 2025, Geospace reported revenue of $24.8 million, compared to revenue of $25.8 million for the comparable year-ago quarter. Net income for the three-months ended June 30, 2025, was $0.8 million, or $0.06 per diluted share, compared to a net loss of ($2.1) million, or $(0.16) per diluted share, for the quarter ended June 30, 2024.

For the nine-months ended June 30, 2025, Geospace reported revenue of $80.1 million compared to revenue of $100.2 million for the comparable year-ago period. Net loss for the nine-months ended June 30, 2025, was ($0.7) million, or $(0.05) per diluted share, compared to net income of $6.3 million, or $0.47 per diluted share, for the nine-months ended June 30, 2024.

Management’s Comments

Richard “Rich” Kelley, Chief Executive Officer and President of Geospace Technologies, said, “Strategic accomplishments defined our third quarter laying the foundation to further our revenue and profitability goals. Our Energy Solutions team won a sizeable contract to supply nearly 500km of the OptoSeis® Permanent Reservoir Monitoring (PRM) system covering 140 sq km of seabed area of Mero, located off the coast of Rio de Janeiro, Brazil. Additionally, Energy Solutions achieved its first sale of the newly released Pioneer™, an ultralight land node for seismic surveys, to a global engineering and professional services firm based in Canada. The delivery of the Pioneer system will occur before the end of the fiscal year. Additionally, we recorded the sale of assets associated with our streamer recovery device product line to Seis Gear, Inc. in June.

Building off this success, we invested in the growth of our Intelligent Industrial segment this quarter with the recently announced acquisition of Heartbeat Detector®, a security technology developed by the United States Department of Energy’s Oak Ridge National Laboratory (ORNL). This advanced system is designed to detect the presence of concealed humans in vehicles of any size. We intend to offer the Heartbeat Detector® on a subscription basis, aligning with our strategy to grow recurring revenue streams. As we increase the emphasis on our security and defense product portfolio, we have engaged former U.S. Border Patrol Chief Carla Provost to educate fellow national and homeland security professionals and accelerate end-user adoption of our advanced analytics and sensing solutions for border and perimeter security applications.

We continue to generate strong organic growth in our Smart Water segment where our Hydroconn® universal AMI connectors remain a reliable revenue and profit center. This quarter, we received an enthusiastic response to our new corporate branding and integrated smart water management portfolio at the American Water Works Association international annual conference and exhibition.

Lastly, we completed the sale of idle property adjacent to our facility for $9.2 million in gross proceeds.”

Smart Water Segment

Third quarter revenue from the Company’s Smart Water segment totaled $10.5 million for the three months ended June 30, 2025. This compares to $9.9 million in revenue for the same period a year ago representing an increase of 6.1%. Revenue for the nine-month period ended June 30, 2025, is $27.3 million, an increase of 32.7% over the equivalent prior year period. This marks a record high level of nine-months of revenue for our Smart Water Segment.

Energy Solutions Segment

Revenue from the Company’s Energy Solutions segment totaled $8.1 million for the three-month period ended June 30, 2025. This compares to $9.4 million in revenue for the same period a year ago representing a decrease of 13.6%. Revenue for the nine-month period ended June 30, 2025, is $35.0 million, a decrease of 42.0% over the equivalent prior year period. The decrease in revenue for the three-month period and nine-month period was due to lower utilization and sales for our marine ocean bottom node rental fleet. The Company is encouraged by the first sale of the newly released ultralight land node known as Pioneer. This indicates the need for increased operational efficiency among geophysical survey companies, who benefit from the lighter weight for faster deployments with smaller crews.

Intelligent Industrial Segment

Revenue from the Company’s Intelligent Industrial segment totaled $6.1 million for the three-month period ended June 30, 2025. This compares with $6.5 million from the equivalent year ago period, representing a decrease of 5.4%. Revenue for the nine-month period ending June 30, 2025, was $17.6 million. This compares to the prior year-ago period of $19.1 million, a decrease of 7.6%. The decrease in revenue for both periods was primarily due to revenue recognized for the three and nine months ended June 30, 2024 on a government contract completed in the fourth quarter of fiscal year 2024 and lower demand for our imaging products. The decrease for both periods was partially offset by an increase in demand for our contract manufacturing services.

Balance Sheet and Liquidity

For the nine-month period ended June 30, 2025, the Company used $18.1 million in cash and cash equivalents from operating activities. The Company generated $35.4 million of cash from investing activities that included $28.4 million in proceeds from the sale of short-term investments and $8.7 million in proceeds from the sale of property, plant and equipment, and $5.1 million of proceeds from the sale of rental equipment, offset by $5.8 million for additions to property, plant and equipment as well as, $1.1 million in additions to the rental fleet. 

As of June 30, 2025, the Company had $25.6 million in cash and short-term investments and maintained an additional borrowing availability of $15.0 million under its bank credit agreement with no borrowings outstanding. For the nine-month period ended June 30, 2025, the Company’s working capital is $74.5 million which includes $32.3 million of trade accounts and financing receivables. Additionally, the Company owns unencumbered property and real estate in both domestic and international locations.
