The investor filing: Form 8-K of Dec 29, 2025. An 8-K is tied to the incident by the company and the dates, so read it before relying on it. It says: "On December 23, 2025, Peoples Financial Services Corp. (the “Company”), bank holding company for Peoples Security Bank and Trust Company, completed a repositioning of a portion of its investment securities portfolio. The Company sold lower-yielding, available-for-sale (“AFS”) U.S."
Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| SEC Form 8-K SEC Form 8-K | Dec 29, 2025 | Not published | 6 days from breach end | 8-K Record |
People is the count the filing gives, residents of the state unless marked total. Days to notice runs from the discovery date the letter states, or from the end of the breach window when no letter states one, to the date on the state's first record of the incident. "Over" marks a count past the days the state's statute allows for notice to residents. The statute's trigger is a question of fact, the days are arithmetic.
