AUSTIN, Texas, May 13, 2026 (GLOBE NEWSWIRE) -- Astrotech Corporation (Nasdaq: ASTC) (the “Company” or “Astrotech”) reported its financial results for the third quarter of fiscal year 2026, which ended March 31, 2026.

Financial Highlights & Recent Developments

● Research and development expense was $554 thousand, a decline of 28% from the third quarter of fiscal year 2026 as the Company transitions from development stage to saleable products for its EN-SCAN Handheld GC and 1^st Detect TRACER 1000 product lines.

● Through March 31, 2026, the Company has deployed the TRACER 1000 trace detection system in approximately 37 locations in 16 countries across the United States, Europe and Asia.

“During the third quarter of fiscal year 2026, we remained focused on disciplined execution, achieving targeted cost-efficiency initiatives while continuing to invest selectively in the highest-return areas of the business. As a result, we are better positioned to operate efficiently in a dynamic macro environment. At the same time, our sales team is advancing a healthy sales pipeline supported by strong lead generation and ongoing customer engagement across key markets. Our deployments to date support these efforts with real-world demonstration of our solution capabilities and compelling data affirming the unique benefits of mass spectrometry technology in industrial, safety and trace detection applications. Looking ahead, we will continue to balance rigorous expense control with strategic investments to help convert pipeline opportunities into revenue growth”, said Thomas B. Pickens, III, Astrotech’s Chairman and Chief Executive Officer.
