Archer Aviation stock has fallen sharply over the past year, yet on simple market multiples it still screens as undervalued, leaving investors weighing weak recent returns against a mixed but not outright negative valuation picture.

• Archer Aviation shares are down 55.9% over the past year, which signals that sentiment around the stock has been under pressure even as news flow has been active.
• The new autonomous aircraft platforms with Anduril and the infrastructure push under the ACES consortium can support long term revenue expectations. However, execution risk around certification timelines and commercial adoption remains a key overhang for what investors are willing to pay today.
• The stock earns a mixed valuation profile with 4 of 6 checks pointing to value, which suggests Archer Aviation is not a clear bargain but does have some areas where the market may be pricing it conservatively.

The issue now is whether Archer Aviation's weak share price performance already reflects these risks or if the current valuation still leaves limited room for disappointment.

Is Archer Aviation a Bargain on Book Value?

Price to book is a useful cross-check for Archer Aviation because the company is still in a heavy investment phase where earnings are not yet a clear guide. On this metric, Archer Aviation trades at a P/B of about 1.6x, compared with an aerospace and defense industry average of around 3.8x and a peer group average near 2.8x.

Even after the recent share move following the Anduril autonomous aircraft news, the stock still sits at a sizable discount to both those benchmarks on book value. That indicates the market is pricing Archer Aviation below the sector on the value of its net assets, despite ongoing partnerships and infrastructure plans that are already public.

On P/B, Archer Aviation stock appears undervalued relative to both its industry and peer averages.

The Bottom Line

Archer Aviation screens as undervalued on simple market multiples, yet the broader set of checks paints a more mixed picture rather than a clear-cut bargain. The discount on book value only really pays off if the company delivers on certification, funding and commercial rollout of its aircraft platforms without major setbacks. For now, the gap between price and assets looks like the market’s way of pricing in those execution and adoption risks. The real dividing line between bulls and bears is whether that caution proves excessive or whether it correctly flags the risk that today’s discount could persist.
