Rocket Lab stock falls after $1.94bn equity raise for Iridium deal

Rocket Lab (RKLB) shares fell 4.79% to $64.57 on 18 September 2026 after raising $1.94bn in equity to fund its acquisition of Iridium Communications. The decline was attributed to investor concern over dilution. The company's backlog stands at $2.36bn, and revenue grew to $234.1m in Q2 2026, though it remains loss-making.
