Archer Aviation Swings as New SEC Filings Put Spotlight Back on Cash Burn

NEW YORK, May 20, 2026, 13:09 EDT

  • Archer shares showed little movement in early afternoon trading, trailing some air-taxi rivals that posted gains.
  • SEC filings this week showed issuance of vendor shares and some executive stock sales linked to tax withholding.
  • Investors are looking at Archer’s 2026 U.S. launch plans, but losses and certification risk remain a concern.

Archer Aviation Inc. shares traded flat Wednesday, steady around $5.94 early in the afternoon. Investors took in new stock-sale filings as the electric aircraft maker said it still aims to start U.S. air-taxi service this year.

The stock traded 0.4% higher at $5.935 as of 12:53 p.m. EDT, moving in a range from $5.75 to $6.035. Volume was about 22.9 million shares, putting the company’s market cap around $4.55 billion.

Archer shares ended little changed. That’s notable since the company is deep into an expensive buildout phase. Archer has yet to convert certification gains into commercial flights, and investors are tracking filings for potential dilution, stock-based compensation, or looming cash demands.

Archer’s CTO Thomas Paul Muniz sold 44,740 shares on May 15 and another 91,839 shares on May 18, according to SEC filings signed May 19. The filings said both sales were to cover tax withholding from the vesting of restricted stock units. Eric Lentell, Archer’s Chief Legal and Strategy Officer, reported selling 39,967 shares and 48,169 shares on those same dates, with the filings citing the same reason.

The filings stop short of showing any open-market buying. They also aren’t solid evidence by themselves that executives have changed their view on the business. But for a pre-profit name where the stock swings on milestones and cash runway, insider sales can make for tough headlines.

Archer said in a May 14 filing it registered the resale of 3,266,870 Class A shares held by selling stockholders. The company also disclosed plans to issue up to $8 million in Class A shares on or about May 19 for payments to some vendors.

Archer said it finished the first quarter with around $1.8 billion in liquidity and “limited debt exposure.” Revenue for the quarter came in at $1.6 million. The company posted a net loss of $217.7 million and an adjusted EBITDA loss of $172.5 million. EBITDA strips out interest, taxes, depreciation and amortization. SEC

Archer Founder and CEO Adam Goldstein said in the results release that the company is “far more than an air taxi company.” He pointed to its defense and software efforts and the commercial aircraft program. “We’re investing and building accordingly,” he said. SEC

Archer Aviation said it sees U.S. operations starting this year through the White House’s eVTOL Integration Pilot Program, aiming to gear up for the 2028 Los Angeles Olympic Games. eVTOL refers to electric aircraft that take off and land vertically, similar to helicopters but fly like planes.

Archer said it’s the first eVTOL firm to wrap Phase 3 of the FAA’s four-step type-certification process for its Midnight aircraft, according to information it had when it put out the release. The last step brings formal tests and analysis to prove the plane meets FAA airworthiness standards.

Peers traded higher on Wednesday. Joby Aviation picked up 3.6% to close at $10.355 and Vertical Aerospace rose 2.1% to $2.40. The SPDR S&P 500 ETF Trust, seen as a U.S. market proxy, added 0.8%.

Certification, manufacturing or airport-network work could drag out longer than investors are betting. Archer’s release said its plans depend on when it gets certification, starts aircraft deployment, builds out vertiport infrastructure and wins defense awards; if those slip, losses stay elevated and Archer might have to sell more stock.

Archer isn’t seeing a reaction in the market after Wednesday’s filings. Shares are moving as if the company still has money to develop its projects, but there isn’t enough evidence yet that air taxis will go from testing and pilot runs to turning a profit.
