Lobbying (Senate LDA, as client)

No LDA filing posted since October 2025 names "Latigo Biotherapeutics, Inc." as the client. Filings under a subsidiary or trade-association name are not matched — search lobbying.

Companies whose stock was traded by the same people who traded LTGO, by number of filers in common. It shows overlap in public filings and nothing else.

Insiders and their transactions come from SEC EDGAR Form 4 filings for this issuer. Contracts and lobbying are matched by exact normalized name (suffixes like Inc./Corp. ignored) to USAspending recipients and LDA clients — a conservative match that misses subsidiaries on purpose.
