Archer Aviation (ACHR) Stock Still Looks Undervalued On Its Asset Base

Simply Wall St·09/19/2026 20:22:25
Listen to the news

Archer Aviation has seen its share price fall sharply over the past year, which puts an uncomfortable spotlight on whether the current US$5.26 level still lines up with the value on its balance sheet. For anyone watching the electric air taxi space, the question now is how much of Archer Aviation's future story is already baked into a stock that has recently been heading lower.

  • Over the past year the share price has declined 46.7%, which raises the question of whether the market is now leaning more on expectations than on the book value that backs each share.
  • The business model is capital intensive, so the pace of asset build and funding needs can strongly influence how closely investors should anchor on its book value when thinking about downside protection.

Is Archer Aviation a Bargain on Book Value?

P/B works well for Archer Aviation because the story today is still much more about its asset base and funding than about mature earnings power.

On this lens, Archer Aviation trades at a P/B of roughly 2.1x, which is almost identical to the peer group average of about 2.1x and below the broader Aerospace & Defense industry on roughly 3.0x. That combination points to a stock that screens as undervalued against the wider sector on balance sheet terms, even if it does not show a clear discount against closer peers that are already pricing in similar capital intensity and risk.

For you as a shareholder or potential buyer, the key question is how much confidence you have that Archer Aviation can turn this equity base into commercial aircraft, service revenue and cash flow over time, because that will decide whether a P/B around 2.1x embeds too little, too much, or roughly the right amount of optimism.
