Astrotech Corporation (ASTC) reported an update to its equity financing arrangements under its existing at-the-market offering agreement with H.C. Wainwright & Co., LLC. The company filed a new prospectus supplement under a recently effective shelf registration statement to permit the offer and sale of up to $50 million of common stock through at-the-market transactions, with Wainwright acting as sales agent. This new supplement replaces and supersedes the prior June 2026 prospectus supplement, under which Astrotech had been authorized to sell up to approximately $24.5 million of common stock. As of August 19, 2026, Astrotech had sold 258,856 shares of common stock for gross proceeds of approximately $7.9 million under the prior supplement, and no further sales will be made under that earlier document. A legal opinion from Haynes and Boone, LLP, covering the validity of the newly registered shares, is filed as an exhibit.
Astrotech Corporation (ASTC) is updating its at-the-market equity program, allowing it to issue and sell up to $50,000,000 of common stock from time to time through H.C. Wainwright & Co. as sales agent. The firm previously sold 258,856 shares under this agreement for about $7.9 million, and those sales are now fully covered by a prior prospectus supplement.
At an illustrative price of $7.94 per share, ASTC shows a scenario of issuing 6,038,373 new shares, which would increase shares outstanding from 2,107,596 to up to 8,145,969. Net proceeds are earmarked for general corporate purposes, with discretion retained by management. The company highlights highly speculative, early‑stage lunar infrastructure and mining “Initiatives” that would require substantial capital and face intense technical, regulatory and competitive risks, and notes a potential sale process for its 1st Detect subsidiary to help fund these plans.
Astrotech Corp. (ASTC) previously registered up to $24,492,819 of common stock for sale in an at-the-market program through H.C. Wainwright & Co. From June 3, 2026 to this supplement date, the company sold 258,856 shares for gross proceeds of approximately $7.9 million.
This supplement terminates the continuous offering under the June Prospectus effective August 19, 2026, and no further shares will be sold under that document. The at-the-market Offering Agreement remains in effect, and any future sales of common stock under it will be made pursuant to a new August 19, 2026 prospectus supplement to the company’s S-3 shelf, which covers up to $50 million of common stock.
