That makes the sale less informative than a discretionary insider sale made without a pre-arranged plan. After the transaction, Lentell still directly owned 85,011 Archer shares and also held restricted stock units tied to as many as 435,687 additional shares, subject to vesting.

At the same time, ACHR shares rose 3.45% on Friday, closing at $6.30.

Archer’s Insider Selling Comes with Important Context

The latest sale also follows two earlier disposals. Lentell sold 3,754 shares in June and another 52,762 shares on August 17, bringing his disclosed sales over the past few months to about 156,500 shares.

Separate filings also show former Archer board member Michael Spellacy selling warrants, including 161,000 warrants on August 20. Those sales appear less important for the stock because Spellacy is no longer a current director and the dollar value involved was small.For ACHR shareholders, the more useful signal will be whether other current executives start making sizable open-market sales, especially outside pre-arranged trading plans. A broader cluster of insider selling would carry more weight than Lentell’s planned sale on its own.
