Insights

Governance Specialist

ADAR1's position approaches a double-digit stake and is disclosed as indirect via managed entities.

ADAR1 Capital Management is reported with 13,860,028 shares (9.9%) of common stock as of March 31, 2026, tied to multiple managed accounts and milestone warrants. The filing identifies the firm as investment manager/sub-advisor, which explains the indirect beneficial ownership structure.

Key dependencies include the exercisability/vesting of the cited milestone warrants and the actual voting/dispositive arrangements across the pooled entities. Subsequent filings or amendments could show changes if warrants vest or are exercised.

Institutional Ownership Analyst

Reported holdings are large enough to be a notable institutional stake but fall below a 10% control threshold in some jurisdictions.

The filing lists ADAR1 Capital Management at 9.9% of 132,032,636 shares outstanding, with ADAR1 GP at 8.5% and Mr. Schneeberger also attributed 9.9%. The percentages are computed using the issuer's stated outstanding share count as of March 31, 2026.

Because the positions are styled as indirect via funds and include warrants, the actual voting power and potential dilution depend on future warrant events. Cash‑flow treatment and any planned transactions are not stated in the provided excerpt.

Key Terms

milestone warrants, beneficially own, shared dispositive power, Schedule 13G/A

4 terms

milestone warrants financial

"Includes ... 7,253,456 shares of Common Stock underlying milestone warrants"

Milestone warrants are rights that let holders buy a company’s stock only if specific goals—such as regulatory approvals, sales targets, or project completions—are met. Think of them as a coupon that only becomes usable when the company hits agreed checkpoints; they matter to investors because they create contingent value and potential share dilution, and they signal which outcomes the company and its backers consider most important.

beneficially own regulatory

"may be deemed to indirectly beneficially own securities held by ADAR1 Partners, LP"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

shared dispositive power regulatory

"Shared Dispositive Power 13,860,028.00"

Schedule 13G/A regulatory

"This Schedule is being filed on behalf of each of the following persons"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
