1. On October 10, 2026, Vertical Aerospace filed a patent infringement countersuit against Archer concerning the Midnight aircraft and related systems, seeking to restrict production or sales and demanding compensation. This litigation adds uncertainty to the production, delivery, and cash outlay of key projects.

2. On October 9, 2026, Archer’s stock price rose by about 5% after Barclays upgraded its rating, followed by short-term profit-taking; Goldman Sachs maintained its “Hold” rating and lowered its target price from $8 to $7, also limiting valuation growth expectations.

3. On October 13, 2026, Federal Reserve officials stated that more restrictive policies are needed. Expectations of tighter interest rate policy may suppress valuations of growth aviation stocks that have high R&D expenditures but have not yet achieved commercialization.
