Tanguler Tolga
Director · Officer · LXEO, ALNY

Everything this person has disclosed to the SEC on Form 4 — across every company they file for — reconstructed from the public record. A filing history, not a tip sheet.
Pattern in the record: open-market sales filed in March in multiple years since 2025 — a recurring calendar cadence, more consistent with scheduled activity than a one-off decision.
Reconstructed holdings
Reconstructed from this person's own Form 4 filings — the total each filing reported owning afterward, priced at the close on the as-of date shown. A filed position can lag the real one.
Direct and indirect holdings (e.g. through a trust or fund) are tagged separately, as filed.
