<div id="readability-page-1"><article> 1st Detect Corporation's detection and analysis mass spectrometry systems deployed worldwide offer the ability to reduce false alarms and strengthen checkpoint screeningAUSTIN, Texas, Dec. 12, 2025 (GLOBE NEWSWIRE) -- Astrotech Corporation (Nasdaq: ASTC) (the “Company” or “Astrotech”) today announced its support of the Department of Homeland Security’s (“DHS”) recent initiative to modernize aviation security screening and technology nationwide. On November 22, 2025, DHS Secretary Kristi Noem announced a $1 billion nationwide plan to upgrade Transportation Security Administration (“TSA”) equipment and security screening. 1st Detect Corporation stands ready to deploy its TRACER 1000™ detection systems to support such initiatives. The Company's TRACER 1000 detection systems, approved by both the TSA for air cargo screening and the European Civil Aviation Conference for aviation security applications, use mass spectrometry to deliver laboratory-grade trace detection in field-deployable systems. While TRACER 1000 is operational at airports internationally and cargo facilities across the United States, the technology has not yet been deployed at U.S. passenger screening checkpoints. The DHS modernization initiative addresses an important need as airports manage record passenger volumes while facing increasingly sophisticated threats. Traditional screening technologies can have higher relative false alarm rates, which result in slower operations, increased costs, and more stress for travelers. &#34;American aviation security isn't just about detecting known threats, it's about building systems resilient enough for threats we haven't encountered yet,&#34; said Thomas B. Pickens III, Chairman and CEO of Astrotech Corporation and 1st Detect. &#34;Mass spectrometry set the standard, lab-grade precision in the field, detecting trace amounts that traditional screening often miscategorizes. As DHS modernizes this critical infrastructure, we believe we are ready to deliver technology that doesn't just meet today's standards but sets tomorrow's.&#34; Addressing the False Alarm Challenge A key advantage of mass spectrometry-based detection is the reduction in false alarm rates compared to conventional screening technologies. False alarms create cascading operational problems, including extended checkpoint delays, wasted security personnel time, missed flights, and frustrated passengers. By providing more accurate molecular identification of threat substances, TRACER 1000 can help security teams focus resources on genuine threats rather than investigating harmless substances that trigger false positives. Immediate Capacity to Scale Unlike technologies that require years of development or manufacturing ramp-up, Astrotech believes that 1st Detect has the infrastructure and capacity to expand production immediately to meet anticipated demand from the DHS modernization program. The Company believes that its Austin, Texas, facility is positioned to support rapid deployment as airports and federal agencies implement upgraded screening infrastructure. &#34;We are offering tested, certified, and ready to deploy technology that is operational today in some of the world's busiest airports,&#34; Pickens added. &#34;We believe we have the capability to scale production to meet the timeline Secretary Noem has outlined.&#34; Supporting a National Security Priority The DHS aviation security modernization plan represents a substantial investment in screening infrastructure. As the initiative moves from planning to implementation, 1st Detect and Astrotech intend to engage with federal agencies, airport authorities, and industry stakeholders to demonstrate how detection and analysis with its mass spectrometry technology can strengthen security posture while improving operational efficiency. For airports and security professionals interested in learning more about TRACER 1000's capabilities and deployment timelines, 1st Detect is available for briefings, demonstrations, and technical consultations.
