13G/A reports passive ownership below 5% by affiliated funds and principals.
The filing shows 1,250,000 shares held by affiliated master funds and attributes shared voting and dispositive power across J. Goldman entities. The percentage is based on March 27, 2026 outstanding shares.
Because the position is reported on a Schedule 13G/A and is under 5%, this is a passive ownership disclosure; subsequent Forms 13D or 13G amendments would reflect any material change.

Schedule 13G/Aregulatory
"This statement is filed by: (i) J. Goldman & Co., L.P."
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.
Beneficial ownershipregulatory
"Amount beneficially owned: The information required by Item 4(a)"
Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
