AI brief of an SEC Form 8-K · Archer Aviation Inc. (ACHR)

Archer Aviation clears US antitrust waiting period for Boeing Wisk, Insitu deal

Neutral Impact 3 of 5 m&a Written later

Archer Aviation said the Hart-Scott-Rodino waiting period has expired for its pending acquisition of Boeing's Wisk Aero, SkyGrid and Insitu subsidiaries, removing one key closing condition. The deal still requires other regulatory approvals and customary closing conditions, and Archer expects it to close by the end of 2026, so shareholders face continuing uncertainty until then.

Key points

  • HSR Act waiting period expired at 11:59 p.m. EDT on September 18, 2026
  • Remaining conditions include certain other regulatory approvals, which the company says are underway
  • Archer expects the transaction to close by the end of 2026
