Ladensohn group updates Symbotic (SYM) 58.2% Class A and 29.2% diluted stake

Rhea-AI Filing Summary

Symbotic Inc.’s major shareholder group, led by David A. Ladensohn, updated its ownership report on the company’s Class A common stock. The reporting persons collectively beneficially own 5,500 Class A shares, 896,213 Class V‑1 shares and 176,035,129 Class V‑3 shares, which are convertible into Class A shares.

Assuming conversion of these Class V‑1 and V‑3 shares, the group would hold 58.2% of Symbotic’s Class A common stock, based on 304,153,253 Class A shares outstanding as of May 4, 2026. On a fully diluted basis, including all classes, they beneficially own 29.2% of the company’s total outstanding common stock.

The amendment reflects a May 15, 2026 distribution by The 2014 QSST F/B/O Perry Cohen of its Symbotic holdings to The Goose Pond Trust and the Diamond Trust, after which the 2014 QSST ceased to be a beneficial owner while the remaining reporting persons continue to hold their reported stakes.

Key Terms

6 terms

beneficial owner financial

"The 2014 QSST F/B/O Perry Cohen ceased to be the beneficial owner of shares of the Issuer on May 15, 2026."

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

fully diluted basis financial

"the Reporting Person beneficially owns 29.2% of the Issuer's total outstanding Class A common stock on a fully diluted basis as of May 4, 2026."

A fully diluted basis counts every share that could exist if all outstanding options, warrants, convertible securities and other rights were exercised or converted into common stock, showing the maximum number of shares outstanding. For investors this matters because it spreads ownership and earnings across that larger share count, like slicing a pie into every possible piece before deciding how big each investor’s slice will be, which affects per-share value and ownership percentage.

OpCo Units financial

"and 10,853,484 common units in Symbotic Holdings LLC ("OpCo" and such units, "OpCo Units") to The Goose Pond Trust"

Schedule 13D regulatory

"This Amendment No. 4 (this "Amendment") to the originally filed on Schedule 13D with the U.S. Securities and Exchange Commission on June 17, 2022"

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.

Class V-3 common stock financial

"Shares of Class V-3 common stock entitles its holders to 3 votes per share and are convertible on a one-for-one basis into shares of Class A common stock"

Class V-1 common stock financial

"Shares of Class V-1 common stock entitles its holders to 1 vote per share and are convertible on a one-for-one basis into shares of Class A common stock"
