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.
