The investor filing: Form 8-K of Jul 10, 2026. An 8-K is tied to the incident by the company and the dates, so read it before relying on it. It says: "Since the date of the original filing, River's investigation has progressed. River has determined that an unauthorized threat actor accessed portions of its network and removed certain data from its environment. River is working to determine the nature and scope of the information involved, including whether any personally identifiable information was affected."
Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| SEC Form 8-K SEC Form 8-K | Jul 30, 2026 | Not published | 8-K Record | ||
| SEC Form 8-K SEC Form 8-K | Jul 17, 2026 | Not published | 7 days from breach end | 8-K Record | |
| SEC Form 8-K SEC Form 8-K | Jul 10, 2026 | Not published | 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.
