Archer Aviation Stock Falls 6.77% After Boeing Acquisition Deal Details Emerge

Archer Aviation Inc. shares fell 6.77% to $6.33 on Wednesday as investors assessed the company's agreement to acquire three Boeing Co. subsidiaries — Wisk Aero, Insitu, and SkyGrid — in an all-stock transaction. Under the deal announced Monday, Archer will acquire Wisk Aero, an autonomous eVTOL developer; Insitu, an unmanned aircraft systems manufacturer generating more than $200 million in annual revenue; and SkyGrid, an airspace intelligence provider.

Boeing will receive newly issued Archer shares equal to nearly 20% of the company's pre-deal share count, resulting in a Boeing stake of approximately 16%. The transaction remains subject to closing conditions and includes an ongoing technology-sharing arrangement between the two companies. CEO Adam Goldstein, speaking on the company's Q2 earnings call on August 11, 2026, said defense contracts offer a faster path to revenue than the commercial air taxi market. CFO Priya Gupta said Insitu is a profitable business expected to contribute positive free cash flow and operate on a self-funding basis, potentially offsetting spending elsewhere. Goldstein said the acquisitions enable a new suite of products capable of generating significantly higher revenue.

For the quarter ended June 30, 2026, Archer reported total revenue of $5.0 million, beating analyst estimates of approximately $1.96 million by about 155%. The company posted a net loss of $263.2 million and an adjusted EBITDA loss of $177.1 million, within its guidance range of $170 million to $200 million. Operating expenses totaled $284.2 million. Archer ended the quarter with $1,560.6 million in cash, cash equivalents, and short-term investments, down from $1,775.9 million in Q1. Shares had risen 11.99% to $6.26 on Monday following the initial deal announcement before pulling back on Wednesday. Cantor Fitzgerald analyst Andres Sheppard reiterated an Overweight rating on Archer Aviation with a $11 price target.

Pairing an unprofitable eVTOL certification program with a profitable defense-linked unmanned systems business is one route companies in this position take to smooth out cash burn while a certified product is still years away. Insitu's stated free-cash-flow contribution and self-funding status would, if realized, offset spending elsewhere in Archer's business without requiring new external capital raises.

How this segment works is that commercial air taxi revenue depends on certification timelines that are hard to control, while government and defense contracts for unmanned systems can generate revenue on a nearer-term basis — Goldstein's comment about defense contracts offering a faster path reflects that structural difference. Boeing's resulting stake near 16% also ties two companies together through an ongoing technology-sharing arrangement rather than a one-time transaction.

Whether the deal delivers on its stated logic will depend on the closing conditions being satisfied and on whether Insitu's contribution materializes as described once the units are integrated into Archer's financials.
