According to a Form 144 filed with the SEC, Archer officer Eric Lentell plans to sell 3,754 Class A shares with an aggregate market value of about $18,764. The proposed sale is expected around June 11, 2026, through Fidelity Brokerage Services.

Meanwhile, ACHR shares dropped 4.15% on Friday, closing at $5.08. Additionally, the stock is down 32.45% year to date.

The Sale Appears Tied to Taxes

The shares were granted as restricted stock that vested on May 15, 2026. The filing states that the “sale includes an amount necessary to cover a tax obligation resulting from the settlement of a vested equity award distribution.”

That is an important detail for investors. Insider sales can sometimes raise questions about management confidence, but tax-related sales tied to equity compensation are common. In this case, the size is also very small. Archer listed 759.6 million Class A shares outstanding in the filing, meaning the planned sale represents only about 0.0005% of that total.
