Astrotech Board Approves Potential Sale Process of 1st Detect and TRACER 1000, the Only Field-Deployed Mass Spectrometry ETD, as the Company Focuses on Its Initiative in Space

AUSTIN, Texas, June 16, 2026 (GLOBE NEWSWIRE) -- Astrotech Corporation (NASDAQ:ASTC) ("Astrotech" or the "Company") today announced that its Board of Directors has approved a potential sale process of its 1st Detect Corporation subsidiary ("1st Detect"), developer of the TRACER 1000 mass spectrometry–based explosives and narcotics trace detection ("ETD") platform. The TRACER 1000 is the only mass spectrometry ETD certified and field-deployed in aviation security operations, at a moment when U.S. and European authorities have signaled a shift away from the legacy ion mobility spectrometry ("IMS") technology that has dominated the market for three decades. The Company is evaluating a potential sale to provide additional capital for the previously announced lunar mining initiative the company is committed to building.

The Board's decision follows a series of regulatory, operational, and technology milestones that management believes have moved 1st Detect past a critical inflection point and materially increased its strategic value. These include the TRACER 1000's TSA approval for the Air Cargo screening; ECAC certification for passenger and cargo screening, including G1 approval and the newly granted ECAC certification for wand swabbing; the Company's entry into the TSA checkpoint certification process through the Transportation Security Laboratory ("TSL"); and a U.S. Department of Homeland Security ("DHS") award to mature the TRACER 1000 for next-generation explosives trace detection.

"There are rare moments when a detection platform holds regulatory validation, government-backed development support, years of field operating history, and a clearly emerging market need at the same time and we believe 1st Detect now holds all four," said Thomas B. Pickens III, Chairman and Chief Executive Officer of Astrotech. "The TRACER 1000 is no longer an emerging technology. It is a field-proven, certified, next-generation ETD platform standing at the front of the industry's transition from legacy IMS to mass spectrometry. The Board believes the right path to unlock that value for shareholders, may be a sale to a strategic or financial buyer capable of accelerating commercialization and worldwide deployment."

A Defined Strategic Window

Management believes the explosives trace detection market is entering a significant transition. For roughly thirty years, the global explosives trace detector (ETD) install base has been built on IMS technology. The Company believes that IMS-based ETDs operate with constrained threat libraries and that adding new lethal compounds to an IMS system can degrade instrument performance, a structural limitation as variations and threat profiles continue to evolve. The Company states that new additions to the TRACER 1000 detection library do not degrade detection capability or increase false alarms, because the TRACER 1000 system uses an extensive and easily expandable threat library. Management believes the significant advantages, highly accurate threat identification with an expandable library, is the reason regulators are moving toward mass spectrometry, and the reason the current moment represents a compelling acquisition opportunity.

Mass Spectrometry: The Next Evolution in Trace Detection

The TRACER 1000 brings laboratory-grade mass spectrometry into real-world, high-throughput security environments, detecting explosives and narcotics in seconds with near-zero false alarms, with an expandable threat library and very low false-alarm rates. Management believes false-alarm performance is not merely a technical metric but an operational and economic one: in high-volume cargo and checkpoint environments, testing thousands of people and cargo per day, false alarms can significantly slow throughput imposing a high cost per alarm.

"Legacy IMS technology was built for a time that required testing for a much narrower threat environment," Pickens said. "Today's aviation, cargo, border, law enforcement and critical-infrastructure operators need a platform that can evolve as threats evolve. We believe the TRACER 1000's expandable library, low false-alarm performance, and field-proven operating history place it at the forefront of that transition."
