Reading these records

First stated window: The timing wording in the earliest company statement located within the sources checked, quoted as written (for example “2H 2026”). An earlier statement may exist outside those sources.
Disclosure date: The date of the filing or company release that disclosed the readout. “None found” means no such disclosure was located in the sources checked. SEC filings were searched through the “SEC filings searched through” date shown.
1H, 2H, 1Q–4Q: First or second half, or first to fourth quarter, of the year named, as the company wrote it. Equivalent notations are compared together; the original wording stays visible.
SEC original: The filing as published on the SEC EDGAR system. “Company original” is the release on the company's own investor site.
Status: One of seven labels set by founder review of the original filings. Definitions: Methodology.
