Should You Buy Archer Aviation Stock While It's Below $6?

Archer Aviation shares have fallen roughly 62% from their October 2025 high of $14.62 to about $5.50, as the company remains deeply loss-making, with Q2 revenue of just $5 million and adjusted EBITDA loss of $177.1 million. Archer is acquiring Boeing subsidiaries Insitu, Wisk Aero, and SkyGrid; Insitu contributes about $200 million in annual revenue and is profitable, but Boeing will receive a 16.5% equity stake, creating substantial dilution. Despite $1.56 billion of Q2 cash, continued cash burn, uncertain eVTOL certification and commercialization timing, and likely further equity issuance keep the investment case high risk, offset partly by Boeing, Stellantis, and Anduril partnerships.

Analysis

The proposed Boeing asset package changes ACHR’s investability more through revenue mix than through near-term eVTOL economics. A profitable defense-drone operation can partially offset corporate burn and give Archer a defense procurement channel, but the market should value that cash flow separately from the air-taxi option: unless the acquired business is transferred at an unusually favorable multiple, it does not justify assigning a higher multiple to the pre-revenue eVTOL operation. The critical unknown is pro forma share count and the standalone profitability/cash-conversion of Insitu; a stock-funded deal may lower financing risk for Archer while still reducing per-share option value materially.

BA is the cleaner near-term beneficiary: it monetizes non-core assets, retains upside through an equity stake, and gains exposure to autonomous aviation without carrying full development and certification costs. STLA’s exposure is strategically useful but not yet economically material; the key read-through is whether its manufacturing commitment translates into funded tooling, binding volume commitments, or merely a partnership headline. JOBY should benefit competitively if the transaction validates strategic demand for eVTOL intellectual property, but Archer’s defense and air-traffic-management additions may narrow Joby’s perceived ecosystem advantage rather than change the certification race.

Near term, ACHR is vulnerable to a post-deal financing overhang as investors model dilution and integration costs. Over 1-3 months, definitive transaction documents, pro forma financials, FAA certification milestones, and any defense backlog disclosure are the relevant catalysts; absent these, the combined story remains a long-duration call option. The contrarian case is that recurring defense revenue can re-rate Archer from a pure cash-burn vehicle to a hybrid defense/autonomy platform, but that requires evidence that acquired earnings fund development rather than disappear into incremental R&D.

Key Decisions for Investors

• Do not initiate a core ACHR long before definitive deal terms disclose pro forma diluted shares, Insitu EBITDA/cash flow, and any assumed liabilities. Reassess only if the acquired operations are demonstrably cash-generative and dilution is below the market’s likely worst-case expectation; otherwise downside remains driven by financing rather than operating execution.
• Express relative certification and capitalization risk with a modest long JOBY / short ACHR pair over the next 1-3 months, sized beta-neutral. The thesis fails if Archer provides credible certification timing plus defense backlog that materially improves its cash runway, or if Joby reports a comparable financing need; use a 15-20% adverse spread stop.
• Maintain or add BA exposure on weakness rather than buying ACHR for the transaction. BA retains asymmetric strategic upside while removing execution-intensive, non-core assets; the trade is invalidated if asset-sale economics reveal meaningful retained obligations or the transaction fails to close.
• Set an ACHR catalyst alert for FAA certification progress, binding aircraft orders with deposits, and a disclosed pro forma quarterly cash burn. A reduction in annualized burn without incremental equity issuance is the necessary signal for a six-to-eighteen-month long thesis; partnership announcements alone are insufficient.
