MAK Capital Fund LP, MAK Capital One L.L.C., and Michael A. Kaufman have disclosed a passive ownership stake in Autolus Therapeutics plc (NASDAQ: AUTL) via Schedule 13G. The group reports beneficial ownership of 15,408,638 American Depositary Shares (ADS), equal to 5.8 % of the company’s 266,141,411 ordinary shares/ADS outstanding as of 7 May 2025. All voting and dispositive authority over the shares is held on a shared basis; none is held solely by any individual entity. MAK Capital Fund is organized in Bermuda, while MAK Capital One L.L.C. and Mr. Kaufman are U.S.-based (Delaware). The filing is made under Rule 13d-1(c), indicating the stake is passive rather than activist; the certification expressly states the securities were not acquired to influence control of the issuer. The event triggering the filing occurred on 17 June 2025, and signatures were executed on 25 June 2025.

The disclosure is material because it crosses the 5 % threshold that requires public reporting, signaling meaningful institutional interest. However, the absence of sole voting power and the passive filing status reduce the likelihood of immediate governance changes. Investors may view the stake as a constructive vote of confidence in Autolus’ long-term prospects without signaling imminent strategic pressure.
