Rocket Lab agrees to acquire Iridium in $8 billion cash-and-stock deal

Rocket Lab agreed to acquire Iridium Communications in a cash-and-stock deal valuing Iridium at about $8 billion enterprise value.

Rocket Lab and Iridium Communications said they signed a definitive agreement for Rocket Lab to acquire all outstanding Iridium common stock, per a joint press release filed as an exhibit to Rocket Lab's 8-K with the SEC on June 29, 2026. Iridium stockholders will receive $27.00 in cash plus Rocket Lab shares under an exchange ratio collared between $67.50 and $112.50, a structure the companies say has a notional value of $54.00 per Iridium share and implies an $8.0 billion enterprise value. Both boards approved the deal unanimously, Rocket Lab has commitments for a $3.6 billion bridge loan from Deutsche Bank and Wells Fargo, and the companies expect to close in mid-2027 subject to Iridium stockholder and regulatory approval. On July 6, 2026, Iridium said it completed its acquisition of the remaining 61% of Aireon, the space-based air-traffic-surveillance venture it did not already own, paying about $367 million to providers in Canada, England, Denmark, Ireland, and Italy, per SpaceNews, consolidating Aireon as a wholly owned subsidiary ahead of the Rocket Lab deal's close.
