Picked up 11,000 shares at 2.27$ after the news about their FDA approval for Utebzi (tebipenem pivoxil) — Oral antibiotic for complicated urinary tract infections (cUTIs), including pyelonephritis, in adults. Commercialized via GSK partnership. This was a major catalyst and should have double the price but instead it did nothing and has since gone down. This drug alone could generate over 1B in sales.

Float: 42.81m shares

Short: 2.86m

52 week range: 1.20 - 3.08

July 14, 2026: Major Licensing & Financing Deals — Spero announced an exclusive license from Innovent Biologics for SP001 (IBI355), a Phase 2-ready third-generation anti-CD40L antibody for immune diseases (e.g., IgG4-related disease). The deal could be worth up to $1.1 billion in milestones.

This stock is way undervalued IMO and could be a great candidate for a buyout.
