Insights

Equity ownership and disclosure analyst

Large holder maintains stake; percentage shifts with share count change.

AyurMaya Capital Management Company, L.P. and David E. Goel report beneficial ownership of 15,139,707 Alumis shares, or 12.3% of the company’s common stock. The amendment clarifies that this percentage change stems from updated shares outstanding, not from trading activity.

The filing indicates shared voting and dispositive power over the full position, meaning decisions on voting and selling are made jointly. With no transactions in the last 60 days, this appears to be an administrative update reflecting Alumis’s new total of 123,432,027 voting shares as of May 5, 2026.

Subsequent Alumis disclosures may show how the overall share count evolves, which in turn can affect the reported ownership percentages of significant holders like AyurMaya without any change in their absolute shareholdings.

6 terms

beneficially owned financial

"for the aggregate number of shares of Common Stock and percentages of the shares of Common Stock beneficially owned by each Reporting Person"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

shared voting power financial

"Shared Voting Power 15,139,707.00"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power financial

"Shared Dispositive Power 15,139,707.00"

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

Reporting Person regulatory

"beneficially owned by each Reporting Person"

Percent of class financial

"Percent of class represented by amount in Row (11) 12.3 %"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.
