(NASDAQ: SERA) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is SERA PROGNOSTICS, INC., listed on NASDAQ under ticker SERA, with ISIN US81749D1072. The LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-DE).

The filings comprise 71 directors' dealings, 60 regulatory filings, 10 results, 4 AGM/EGM notices, 3 corporate news, 3 director changes and 1 prospectus. The median gap between filing days is 5 days.

The segment move is not on the record (the exchanges' tier transfers are not EDGAR filings). The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable. The chapter's orderability section carries no client categories, so the outcome cannot name its client category. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations pages read.
