ASTROTECH REPORTS FISCAL YEAR 2018 FINANCIAL RESULTS

Austin, Texas – September 24, 2018 – Astrotech Corporation (NASDAQ: ASTC) reported its financial results for the fourth quarter and fiscal year ended June 30, 2018.

Thomas B. Pickens III, Chairman and CEO of Astrotech, stated, “Fiscal 2018 was an excellent year in terms of product endorsement at 1^st Detect. We achieved three major milestones toward our goal of securing airports, borders, package distribution centers, and other public venues from explosive threats, as we strive to modernize the explosives trace detector (ETD) market.” The three milestones include:  

1. 1^st Detect began Test and Evaluation (T&E) activities at the Department of Homeland Security’s Transportation Security Laboratory (TSL). The TRACER 1000 is currently undergoing Developmental Test and Evaluation (DT&E), and is expected to enter Independent Test and Evaluation (IT&E) in the coming months. A successful IT&E review would lead to TSL Certification. Once TSL Certification is complete, our product is ready to undergo TSL Qualification Testing and field trials, the result of which is a recommendation of whether the system should be placed on the Qualified Products List (QPL), which is necessary for deployment in U.S. airports.

2. The TRACER 1000 was accepted into the Transportation Security Administration’s (TSA) Air Cargo Screening Technology Qualification Test (ACSQT) program. Certification under this program would enable the TRACER 1000 to be purchased for use in air cargo handling facilities throughout the United States, to include both package distribution centers and checked luggage at airports. This summer, the TRACER 1000 underwent substantial testing at one of the world’s largest package distribution companies, as well as at a major U.S. airline’s cargo facility. Results from these tests will support the data package for submission into the ACSQT program.

3. 1^st Detect applied to and was accepted into the European Civil Aviation Conference (ECAC) Common Evaluation Process (CEP) for both aviation checkpoint and cargo security. ECAC Certification under this program would enable the TRACER 1000 to be sold to airports throughout Europe and other non-U.S. countries. Testing under this program kicked off this month and we anticipate feedback in the coming months.

There is no assurance that any of the further steps detailed in the milestones mentioned above will be achieved or that our technology will be approved by any of the programs listed.

“We believe these three programs represent the airport security and detection industry’s most rigorous technology review programs,” continued Pickens. “Government and commercial customers throughout the world consider certifications under these programs in their procurement decisions and investment strategies.

"The TRACER 1000 would be the first certified ETD driven by mass spectrometry, a technology that we believe offers far superior detection as compared to the currently-deployed, ion-mobility spectrometry (IMS)-based ETDs. With a near-zero false alarm rate, very high levels of specificity, and a considerably expanded library of compounds, our solution is expected to fill critical security gaps by improving screening efficiency, increasing throughput, and enabling officials to stay ahead of evolving threats.

“At Astral Images, we entered into a partnership with ColorTime, a leading post-production house, to incorporate our proprietary Image Correction and Enhancement (ICE™) software and scanner hardware into their workflow. With ColorTime’s customer base comprised of many major film studios, we are encouraged by the potential for our products to gain exposure on a larger scale,” concluded Pickens.

Fiscal Year Financial Highlights

Management continues efforts to optimize our resources while reducing cost and adding financial flexibility.

• On July 3, we announced the filing of a universal shelf registration statement on Form S-3 with the United States Securities and Exchange Commission (SEC). On August 20, the shelf registration statement became effective. The shelf registration statement provides flexibility in regards to our capital raising options. 

• Currently, monthly cash burn has been reduced to just over $750 thousand, a 15.0% reduction from our run rate in fiscal year 2018.  This decrease was mainly driven by a reduction of headcount, optimizing our workforce, and an ongoing emphasis on cost reduction.  Further, this represents a 33.3% decrease from the end of fiscal year 2016, when such cost cutting measures began.

• Astrotech Corporation had no debt at June 30, 2018.
