The shelf is now live — watch for a prospectus supplement (424B5) indicating an actual takedown. Any offering announcement would be highly dilutive given the $19M market cap. Traders should monitor daily for a 424B5 filing and consider short positioning if an offering is announced.

Executive Summary
Astrotech's S-3 shelf registration (File No. 333-297144) was declared effective by the SEC on July 7, 2026. This allows the company to sell up to $200 million in securities (from the June 2026 S-3) or $30 million (from the January 2026 S-3) at its discretion, creating a persistent dilution overhang given the company's ~$19M market cap. The effectiveness removes the final regulatory barrier to potential capital raises, which could be highly dilutive for existing shareholders.
