Archer Aviation (ACHR) shares jumped 11.99% to close at $6.26 on Monday after the electric vertical takeoff and landing developer announced it would acquire three autonomous flight units from Boeing in an all-stock transaction. Trading volume swelled to 128.3 million shares, far above the daily average, lifting the company’s market capitalization to roughly $4.2 billion.
Under the agreement, Archer will take over Wisk Aero, SkyGrid, and Insitu. Boeing receives no cash; instead, it gets newly issued Class A common shares equal to 19.75% of the shares outstanding immediately before closing, along with two warrants each valued at about $100 million and a board seat. Boeing is subject to a lock-up of at least one year. The parties expect to close by year-end, with a final deadline of May 9, 2027, subject to antitrust and national security approvals.
Among the three assets, military drone maker Insitu is the largest by revenue. Archer described the business as profitable, with annual revenue exceeding $200 million and customers across 35 countries. Archer’s own annual sales, by contrast, remain in the single-digit millions. Wisk is developing an autonomous air taxi; its latest model first flew in December 2025 and a certification application is under review by the Federal Aviation Administration. SkyGrid supplies automated airspace management software that coordinates unmanned aircraft with conventional traffic in shared airspace.
Chief Executive Officer Adam Goldstein called the deal a key step toward building a diversified platform, rapidly expanding revenue, and bringing scale to the business. Boeing executive Brian Yutko said the transaction would create an industry leader in the advanced air mobility market. Archer plans to combine the acquired autonomous technologies with its internal artificial intelligence efforts to build an end-to-end physical AI platform for aerospace and defense.
Archer also reported second-quarter results after Monday’s close. The net loss widened quarter-on-quarter to $263.2 million, and cash on hand at the end of June stood at about $1.56 billion, a decline of roughly $215 million from the first quarter. While the company continues to spend heavily on an air taxi that has yet to receive passenger-carrying certification, the immediate addition of a revenue-generating, profitable business is viewed by the market as a potential financial lifeline.
Boeing has not yet supplied audited financials for the units being sold. Some analysts cautioned that without detailed audited numbers, the true quality of the assets remains uncertain, noting that descriptions such as “profitable” and “revenue exceeding $200 million” are Archer’s own characterizations. The same analysis pointed out, however, that the deal already makes Archer a stronger company than it was on Friday. If the transaction ultimately extends Archer’s financial runway and opens new lines of business in a meaningful way, the significant share dilution could prove worthwhile.
