Insights

BVF discloses a near-10% Immunic stake built with layered warrants and a royalty swap.

BVF and related entities report beneficial ownership of 13,630,601 Immunic shares, or about 9.99% of the common stock, combining outright shares and a limited portion of 2026 pre-funded warrants. Multiple funds and a managed account hold additional 2024, 2025 and 2026 pre-funded warrants and Common Warrants that are currently blocked from exercise by 9.9%–9.99% ownership caps.

The group recently participated in a private placement, buying 2026 pre-funded warrants and matching Common Warrants at $0.873120 per 2026 pre-funded warrant plus Common Warrant unit, for a total of 53,257,500 2026 pre-funded warrants and 53,257,500 Common Warrants across vehicles. These instruments give significant optionality tied to future share price and a planned reverse stock split of at least 10:1.

A separate Royalty Purchase Agreement exchanged 51,087,000 Series B warrants for a collective 5% synthetic royalty on future vidofludimus calcium sales, shifting some upside from equity into a product-linked stream. BVF principal R. Thorvald Nagel joining the board adds governance influence alongside the economic stake. Overall, this describes a concentrated, actively structured position rather than a routine passive holding.

FAQ

How much of Immunic (IMUX) stock do BVF and affiliates beneficially own?

BVF and affiliated entities report beneficial ownership of 13,630,601 Immunic shares, representing about 9.99% of outstanding common stock. This total combines direct shareholdings and a limited portion of 2026 pre-funded warrants that can be exercised without breaching 9.99% ownership caps.

What types of Immunic securities have BVF funds recently purchased?

BVF funds bought 2026 pre-funded warrants and matching Common Warrants in a private placement at $0.873120 per 2026 pre-funded warrant plus Common Warrant. Across BVF vehicles, they hold 53,257,500 2026 pre-funded warrants and 53,257,500 Common Warrants, adding to earlier 2024 and 2025 pre-funded warrant positions.

What is the synthetic royalty BVF helped structure on Immunic’s vidofludimus program?

Certain Series B warrant holders exchanged 51,087,000 Series B warrants for a pro rata share of a 5% synthetic royalty on future vidofludimus calcium sales. Each holder’s share equals its exchanged warrants divided by total exchanged warrants, with royalties payable quarterly after first commercial sale.

How do the ownership blockers affect BVF’s Immunic warrant exercises?

The 2024, 2025 and 2026 pre-funded warrants, and the Common Warrants, include 9.9% or 9.99% ownership blockers. These clauses prevent exercises that would lift beneficial ownership above those thresholds, currently limiting exercisability of many warrants despite their immediate exercisability and low $0.0001 per-share exercise price.

What reverse stock split is planned for Immunic according to this disclosure?

Immunic agreed to seek stockholder approval for a reverse stock split of its common shares at a ratio of not less than 10:1. A preliminary proxy must be filed within three days after the private placement closing, followed by a definitive proxy once permitted under securities regulations.

What board and governance changes at Immunic involve BVF representatives?

R. Thorvald Nagel, a principal at BVF Partners, has been appointed to Immunic’s board as a Class III director, effective at the private placement closing. An agreement requires him to transfer to BVF Partners any economic benefit from Immunic securities he receives in his capacity as a director.
