Legato Merger Corp. III (Nasdaq: LEGT), a blank-check company sponsored by Legato Capital Management, filed a Form 15-12G with the SEC on June 23, 2026, formally terminating its Section 12(g) Exchange Act registration and signaling the conclusion of the vehicle's public-company lifecycle. The SPAC, which went public in 2022 under a generalist acquisition mandate with a focus on financial services and adjacent sectors, did not complete a qualifying business combination before its deadline, placing it among the wave of post-peak SPACs that have wound down without a deal. The deregistration filing closes out LEGT's SEC reporting obligations.
