The shelf is now live — Perceptive can sell at any time. Monitor for a Form 4 or SC 13D/A indicating a reduction in Perceptive's stake, which would confirm selling pressure. The $1.9314 floor is ~8.5% below the $2.11 close at filing, so any near-term weakness toward that level could trigger accelerated sales.

Executive Summary
The SEC declared effective Autolus Therapeutics' S-3 shelf registration (File No. 333-298910), filed 11 days earlier. The shelf registers 3,500,000 ADSs for resale by Perceptive Credit Holdings as a warrant sweetener from a July 2026 note purchase — a contractual obligation, not a new capital raise by the company. The effectiveness removes the last procedural barrier for Perceptive to sell shares at $1.9314, creating modest near-term overhang (~1.3% of shares outstanding) with no proceeds to Autolus.
