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

Archer Aviation shares are down roughly 62% from their October 2025 high of $14.62 to around $5.50, reflecting substantial uncertainty around eVTOL commercialization, persistent losses, and future dilution. The company generated only $5 million of Q2 revenue and posted a $177.1 million adjusted EBITDA loss, while guiding for a further $120 million-$170 million loss in the current quarter. Archer is acquiring Boeing subsidiaries Insitu, Wisk Aero, and SkyGrid in an all-stock deal that gives Boeing a 16.5% stake; Insitu contributes about $200 million in annual, profitable revenue, but the transaction materially dilutes existing holders. Archer ended Q2 with $1.56 billion in cash, but continued cash burn and its certification gap versus Joby suggest capital raises and losses are likely to persist.

Analysis

The transaction changes ACHR from a pure-play pre-revenue eVTOL valuation into a mixed aerospace/defense platform, but the market is likely to discount the acquired cash-generating operations until purchase accounting, minority-interest terms, and post-close capital needs are disclosed. Stock-funded consideration effectively makes BA a strategic seller with a meaningful ongoing exposure to ACHR; any subsequent Boeing monetization would create an overhang independent of operating execution. The key near-term issue is therefore not whether acquired revenue improves the headline multiple, but whether it reduces quarterly cash burn enough to defer the next equity raise.

JOBY is the cleaner relative beneficiary. ACHR's broadened defense and software footprint may improve its long-run strategic position, but it also adds integration burden precisely when certification and manufacturing execution require management focus. A widening certification lead for JOBY over the next 1-3 months would reinforce the view that ACHR is buying optionality rather than accelerating commercial air-taxi cash flows; conversely, a credible FAA milestone or binding production commitment could close that gap quickly.

BA gains a non-core asset divestiture route while retaining upside through its equity stake, potentially improving capital allocation optics without foregoing exposure to autonomous aviation. STLA's economic benefit is longer dated: it has a low-capital option on next-generation aerospace manufacturing, but meaningful earnings attribution remains unlikely within 6-18 months. The contrarian opportunity is ACHR only if Insitu's profitability and contract durability are sufficient to fund a material portion of corporate overhead; absent that evidence, the apparent revenue step-up risks masking dilution and negative free-cash-flow persistence.

Key Decisions for Investors

• Maintain a 1-3 month relative-value position: long JOBY / short ACHR in equal dollar amounts. JOBY offers the cleaner certification catalyst, while ACHR faces integration and financing uncertainty; exit if ACHR discloses acquired operating cash flow sufficient to reduce consolidated burn materially or achieves a material FAA certification milestone ahead of JOBY.
• Do not initiate an outright ACHR long before transaction documents disclose pro forma share count, acquired backlog, customer concentration, and Insitu cash conversion. Treat a post-close equity raise, or guidance implying no burn reduction, as a short/underweight trigger rather than a buying opportunity.
• For BA holders, retain exposure but do not add solely on the deal: the strategic stake is a long-dated call option rather than a near-term earnings driver. Reassess if BA identifies cash proceeds, reduced liabilities, or recurring cost savings from the divestiture; without those, the valuation impact should be modest.
• Watch ACHR's cash balance and quarterly operating cash flow over the next two earnings reports. If the implied funding runway remains below 18 months after closing, expect dilution risk to dominate any acquired-revenue rerating; avoid long exposure until financing terms are known.
