Rocket Lab Sold $1.9 Billion of New Stock to Pay for Iridium. Here's the Dilution Math.
Rocket Lab (RKLB) said its $1.94B at-the-market stock sale (about 29.3M shares) fully funds its planned acquisition of Iridium (IRDM). It terminated a $3.6B bridge loan. The sale implies about 4.5% to 5% dilution, with additional shares from the stock portion.
How this was made

The 30-second read
Why it matters
The equity raise reduces debt exposure but introduces dilution; the cash payout offers immediate value to Iridium shareholders. Successful completion could create a vertically integrated space services company.
Market read
The financing structure of a $8 billion acquisition is material for both companies and the broader space sector, influencing valuation and investor sentiment.
What to watch
Potential regulatory hurdles and integration risks could delay or diminish expected synergies.
Background
Rocket Lab is a small but growing launch provider; Iridium operates a global satellite communications network. The acquisition aims to combine launch capability with a large satellite fleet.
Ticker impact

Iridium shareholders will receive $27 per share in cash and stock for the pending acquisition by Rocket Lab, with a vote scheduled for Sept 24.
Iridium stock likely to rise on approval and cash payout, then be delisted post‑merger.
Cash component and stock swap terms are disclosed; market will price in the premium and merger completion risk.
Market effects
