Rocket Lab (RKLB) shares traded between roughly $60.50 and $68.60 during the week of September 14, 2026, amid elevated volume and volatility. The primary driver was the company’s completion of a $1.94 billion at-the-market equity offering to fully fund its pending Iridium Communications acquisition, which cleared an initial FCC hurdle and is slated for a mid-2027 close pending shareholder approval on September 24. This capital raise followed record Q2 2026 results showing $234 million in revenue (up 62% year-over-year), a $2.36 billion backlog, and multiple new launch contracts, including a $266 million U.S. Space Force award. A successful 16th Electron mission of the year further supported sentiment, though the financing introduced near-term dilution concerns and contributed to a sharp reversal after the September 17 rally.
