For the three-months ended June 30, 2026, Geospace reported revenue of $15.8 million compared to revenue of $24.8 million for the comparable year-ago quarter.

Management Comments

Richard “Rich” Kelley, President and CEO of the Company said, “Challenging market conditions across our business segments continued to impact our short-term financial performance. Revenue was impacted by geopolitical uncertainty, project timing, sales volumes and customer access to capital. Product mix, inflation, raw material costs and component availability had significant impacts on margin performance. We were able to offset some of this impact with previously stated cost reduction efforts and improvements in manufacturing productivity. Our financial performance this quarter does not reflect the strength of our long-term opportunities across our diversified markets. We remain focused on the factors within our control and on strengthening the foundation for future performance. Our underlying business remains well positioned with a diversified solutions portfolio and strong technology offerings.

Our Smart Water segment continued its dip in revenue, which is driven in large part by reduced orders of the Hydroconn® connector. In June, at the American Water Works Association Annual Conference and Exposition (ACE), we announced the release of the Series V connector, providing our customers increased flexibility to address increasing supply chain challenges. With this new product release, we offer the most universally compatible portfolio of smart water meter connectors and adapters available domestically.

Our Intelligent Industrial segment remains a consistent revenue contributor with expected future revenue growth from our security portfolio. At the end of the third quarter, our subsidiary, Quantum Technology Sciences, LLC., received a $10.8 million firm-fixed price contract to deliver the seismic acoustic detection and ranging system to the U.S. Navy. The contract is expected to be completed by December 2027. Also, the U.S. Department of Homeland Security exercised an extension option in our existing contract to extend on-going maintenance for an additional six-months.

The Energy Solutions segment generated less revenue than a year ago due to continued reduced demand for seismic acquisition equipment. Third quarter revenue contribution from the PRM contract was lower than was expected due to customer requested changes to the project scope. Importantly, our customer agreed to extend the PRM contract period of performance to account for these modifications. We have now successfully entered full production of the goods contract.

We will continue executing our strategic priorities, investing in innovation, supporting our customers, and maintaining financial discipline. We are focused on converting the opportunities in our pipeline into revenue and improved operating performance. Our priorities remain clear: execute on existing programs, expand the markets for our technology, improve performance in Smart Water, and allocate capital prudently. We believe these actions provide the clearest path to strengthening Geospace's performance over time and creating long-term value for our customers and shareholders.”

Smart Water Segment

The Company’s Smart Water segment generated revenue of $4.6 million for the three-month period ended June 30, 2026. Revenue for the three-month period ended June 30, 2025, was $10.5 million, a decrease of 56.1%. Revenue for the nine-month period was $14.1 million compared to $27.3 million from the same prior year period. The decline in revenue for the three-month period and nine-month period reflects lower demand for the Company’s Hydroconn connector product line, which is primarily attributed to reduced demand for our Hydroconn Series III connector.

Energy Solutions Segment

Third quarter revenue from the Company’s Energy Solutions segment totaled $5.9 million for the three months ended June 30, 2026. This compares to $8.1 million in revenue for the same period a year ago representing a decrease of 28%. Revenue for the nine-month period ended June 30, 2026, is $30.1 million, a decrease of 13.9% over the equivalent prior year period of $35.0 million. The decrease in revenue for the three months was due in part to the sale of assets associated with our streamer recovery device in the prior year. The decrease in revenue for the nine-month period is attributed to lower market demand for our ocean bottom nodal products partially offset by revenue recognized on our PRM contract and Pioneer wireless land node product sales. Despite short-term manufacturing delays, which have been resolved, PRM delivery is expected to occur in the third quarter of fiscal year 2027.

Intelligent Industrial Segment

Revenue from the Company’s Intelligent Industrial segment totaled $5.2 million for the three-month period ended June 30, 2026. This compares with $6.1 million from the equivalent year ago period, representing a decrease of 14%. Revenue for the nine-month period ending June 30, 2026, was $16.7 million, compared to revenue of $17.6 million for the comparable year-ago period. The decrease in revenue for both periods was driven by lower demand for the Company’s industrial sensors. The decrease for the three-month period was also due to a decrease in demand for the Company’s contract manufacturing services.

Balance Sheet and Liquidity

For the nine-month period ended June 30, 2026, the Company used $27.3 million in cash and cash equivalents from operating activities. The Company generated $6.2 million of cash from investing activities including $9.4 million in proceeds from the sale of rental equipment, partially offset by $3.3 million for additions to property, plant and equipment. 

As of June 30, 2026, the Company is in compliance with loan covenants and maintains full access to its credit facility. As of June 30, 2026, the Company had working capital of $40.6 million, including $17.5 million in trade accounts and financing receivables.
