Autolus Therapeutics Enters $250M Senior Secured Notes Facility

What Happened Autolus Therapeutics plc (AUTL) announced on July 30, 2026 that it entered a Note Purchase Agreement with Perceptive Credit Holdings V, LP to establish a senior secured notes facility of up to $250.0 million and issued the first tranche of $75.0 million on the closing date. The facility matures July 30, 2031, bears interest equal to a margin of 6.75%–7.25% (based on recent revenue) plus the greater of one‑month SOFR or 3.50%, and is secured by a first‑priority lien on substantially all existing and after‑acquired assets and guaranteed by key subsidiaries. At closing Autolus also issued Perceptive a warrant for 3,500,000 ADSs (exercise $1.9314 per ADS); additional warrants (up to 2.5M ADSs each) will be issued if Tranche 3 and Tranche 4 are drawn.

• Interest: applicable margin 6.75%–7.25% plus max(1‑month SOFR, 3.50%); default rate increases by +4.00% (and may increase automatically on payment/bankruptcy defaults).
• Warrants: 3,500,000 ADSs issued at $1.9314/ADS (25% premium to 30‑day VWAP prior to closing); additional warrants of up to 2.5M ADSs each on Tranche 3 and 4 issuances; all expire July 30, 2036; warrants may be exercised cashless and are freely transferable but not registered for U.S. resale without exemption.

• Tranche timing/conditions: Tranche 2 (up to $25M) available through Jan 30, 2027; Tranche 3 (up to $75M) and Tranche 4 (up to $75M) become available only if certain Consolidated Net Revenue targets are met by July 31, 2028 and Jan 31, 2030, respectively.
• Registration rights: Autolus must file an initial registration statement covering resale of the issued warrant (and eligible future warrants) within 45 days of the closing.

Why It Matters This transaction provides Autolus with immediate liquidity ($75M received at closing, up to $250M available) to fund operations or development programs, but also increases leverage and fixed financing costs due to relatively high interest margins and fees. The facility is secured and contains financial covenants and default provisions that, if breached, could accelerate repayment or increase interest costs. The warrants issued to Perceptive create potential future dilution if exercised (initially 3.5M ADSs, with up to 5.0M more tied to future tranches), although the initial warrant price reflects a 25% premium to recent market levels. Investors should weigh the added runway against higher interest expense, covenant constraints, and the dilutive impact of the warrants.
