Insights
Large passive stake reported: 10% ownership disclosed by ACR-affiliated group.
The filing shows 5,278,501 shares held collectively, equal to 10.0% of the outstanding common shares (52,595,933 as of February 25, 2026). The disclosure aggregates holdings across partnerships, management entities, and a family trust with shared voting and dispositive power.
Dependencies include whether the holdings are actively managed or held for investor accounts; subsequent filings could update percent ownership if holdings change. Cash-flow treatment and planned transactions are not described in the excerpt.
Filing clarifies voting/dispositive arrangements and routine Section 13(g) disclaimers.
The report names each Reporting Person and specifies shared voting and shared dispositive power for the listed shares, plus explicit disclaimers that several entities "disclaim beneficial ownership" for Section 13(d)/13(g) purposes. The document ties percentages to the issuer's reported outstanding shares.
Key items to watch in future filings include any change to sole voting/dispositive power or conversion of this passive disclosure into an active Schedule 13D; timing of such changes is not provided here.

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.

Schedule 13G/Aregulatory
"This statement is filed by (i) ACR Opportunity, 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.
