Rocket Lab Corp.

(NASDAQ:RKLB) shares slipped in early trading Tuesday after the company signaled a narrowing window for the first flight of its Neutron rocket.

Stage 1 tank production still aligns with delivering Neutron to the launchpad in the fourth quarter of 2026, but Rocket Lab stopped short of reaffirming a first flight before year-end.

RKLB stock is moving.
