(NASDAQ: CABA) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Cabaletta Bio, Inc., listed on NASDAQ under ticker CABA, ISIN US12674W1099; its LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-DE). Its security type is Corporate, its segment is not on the record, its sector is 2836 Biological Products, (No Diagnostic Substances), and its jurisdiction is United States, Delaware. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 66 filings across 31 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 5.5 days. The latest filing is dated 2026-11-06, two days before the record date, and is a regulatory filing. Exchange peers on NASDAQ (4,359 issuers) have a median cadence gap of 6.0 days, a median of 52 filings and a median latency of 5.0 days. Sector peers (176 issuers) have a median cadence gap of 5.5 days, a median of 65.5 filings and a median latency of 4.0 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\nThe issuer's investor-relations page names 10 research houses: Cantor Fitzgerald, Citi, Evercore ISI, Guggenheim, H.C. Wainwright, Jefferies, Morgan Stanley, TD Cowen, Wells Fargo and William Blair.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded.
