SIMPSON THACHER & BARTLETT LLP

SIMPSON THACHER & BARTLETT LLP is a Limited Liability Partnership registered in NEW YORK, United States and holds an LEI in its own name.

The LEI has been on record for 13 years, since 19 Apr 2013. That is about 6 years earlier than the median LEI in United States, which dates from 2019 — an early adopter by local standards.

The next annual re-validation is due 11 Jun 2027, 226 days from now.

The record has not changed since we began archiving it on 6 Jul 2026. Any future change to name, status, address, ownership or renewal date will be captured here, because GLEIF publishes only the current state and superseded values are otherwise lost.

The LEI is issued and maintained by Ubisecure Oy, one of the Local Operating Units accredited by GLEIF.

No direct accounting-consolidating parent is reported, because the parent is not publicly disclosed. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

No ultimate accounting-consolidating parent is reported, because the parent is not publicly disclosed. GLEIF requires this to be stated explicitly rather than left blank, so the absence is itself a data point.

The LEI registration is issued, and the entity status (active) records whether the legal entity itself still exists. The two are independent: an LEI can lapse while the company trades on, and it can stay issued after the company has been dissolved.
