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.
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.

Private transactionmarket
"sold an aggregate of 600,000 shares of Voting Common Stock in a private transaction"
A private transaction is the sale or transfer of securities, assets, or ownership stakes carried out directly between a small number of parties rather than on a public exchange. For investors it matters because these deals are less visible and often less liquid than public trades, so pricing can be harder to verify, the investment can be harder to sell quickly, and buyers or sellers may gain strategic advantages not available in open markets — like negotiated terms similar to a private garage sale versus a crowded marketplace.
What changes did Patriot Financial report in the COSO Schedule 13G/A?
Patriot Financial reported a private sale of 600,000 shares at $25.00 per share and the conversion of 132,156 non‑voting shares into Voting Common Stock on April 30, 2026. The filing updates ownership percentages using the stated outstanding share count.
How was the percent ownership calculated in the filing for COSO?
Percentages use 11,853,258 shares outstanding as of March 31, 2026. The filing explicitly cites that figure and adds the April 30, 2026 conversion when computing reported ownership percentages like 5.8%.
Who sold shares and at what price according to the filing?
The filing states that Patriot Financial Partners II, L.P. and Patriot Financial Partners Parallel II, L.P. sold an aggregate of 600,000 shares in a private transaction at $25.00 per share on April 29, 2026.
Did the filing show who received proceeds from the sale of COSO shares?
Yes. The sale is described as a private transaction by the reporting persons, indicating proceeds were received by those selling holders. The filing names the selling entities but does not allocate proceeds beyond that description.
What is the reported voting stake for key Patriot entities after the transactions?
Cover entries show shared voting/dispositive holdings of 691,367 shares for several related reporting persons, shown as approximately 5.8%, based on the stated outstanding share count as of March 31, 2026.
