Archer Aviation Inc. (ACHR) disclosed that it has filed a prospectus supplement related to shares of Class A common stock issued to certain vendors in exchange for services and/or goods. These issuances, referred to as the Vendor Share Issuances, had been previously described in Archer’s periodic reports.
The prospectus supplement covers the resale of 8,261,273 shares of Class A common stock (the “Resale Shares”) that were issued to vendors on or about August 17, 2026 under stock purchase agreements. The Resale Shares were issued in reliance on Section 4(a)(2) of the Securities Act of 1933, and Archer states that it did not receive any cash proceeds from this issuance.

Archer Aviation reported second quarter 2026 results and outlined a major strategic expansion with Boeing. Archer entered into agreements to acquire Boeing’s Wisk Aero, Insitu and SkyGrid in an all‑stock deal that would give Boeing a strategic equity stake and ongoing collaboration. Insitu is described as profitable with over $200M in annual revenue and operations in 35 countries, while Wisk and SkyGrid add advanced autonomy and airspace‑management technology to support Archer’s Halo/Thunder VTOL platform and its aviation AI model, ZEE.
For the quarter ended June 30, 2026, Archer generated $5.0M in revenue, up from $1.6M in Q1 2026, and incurred total operating expenses of $284.2M, resulting in a net loss of $263.2M. Non‑GAAP total operating expenses were $192.2M, and Adjusted EBITDA was a loss of $177.1M, near the low end of guidance. Archer ended Q2 with $1,560.6M in cash, cash equivalents and short‑term investments plus $7.3M in restricted cash, a decline of $215.3M from Q1 largely driven by operating cash outflows, capex and a Hawthorne Airport FBO acquisition. For Q3 2026, Archer forecasts an Adjusted EBITDA loss between $170M and $200M.
Archer Aviation Inc. signed a definitive agreement with The Boeing Company to acquire all equity interests in Wisk Aero, SkyGrid, Insitu and related entities, adding autonomous aviation, unmanned aircraft systems and digital airspace management capabilities.

Consideration will be paid in newly issued Class A shares and warrants to Boeing in a private placement under Section 4(a)(2), with Boeing agreeing to a 12‑month Lock‑Up, subject to hedging and pledging exceptions. Warrants carry a 19.9% beneficial ownership limitation, exercisable in cash or on a cashless basis and subject to stockholder‑approval mechanics that can temporarily require cash‑settled Replacement Warrants.
Archer will grant Boeing registration rights for the consideration securities, with deadlines for filing and effectiveness and potential fee payments if deadlines are missed. Boeing will have the right to designate one director while it holds at least 10% of pre‑closing Class A shares. A separate Forward Equity Purchase Agreement allows Archer, alongside a third‑party equity offering expected to raise at least $400.0 million, to require Boeing to purchase up to $55.0 million of additional shares before a defined Expiration Date. The Purchase Agreement includes reciprocal indemnities supported by a representation and warranty insurance policy and can be terminated on several grounds, including failure to close by May 9, 2027 (subject to possible extensions).
