Analysis: a cash-flow business bought with borrowed money
The pro formas describe a transaction in which a loss-making manufacturer acquires a profitable subscription operator and funds the cash half with debt. Iridium reported total revenue of $225,237 for the second quarter against $216,906 a year earlier, and $444,294 for the half against $431,784, with approximately 2,627,000 billable subscribers at June 30, 2026, up 144,000 or 6% year on year. That is slow, dependable growth attached to an installed base. Rocket Lab’s own numbers are the opposite shape: faster growth, negative operating income.
The pro forma interest line is where the two meet. Adding $141,357 of interest over six months converts a combined operating loss of $106,090 into a net loss of $154,677 even after a $32,851 tax benefit on the financing adjustment. Iridium’s existing term loan, priced at SOFR plus 2.25% with a 0.75% floor and running to September 2030, is being repaid rather than assumed, so the deal replaces long-dated debt at a known spread with a 364-day bridge at an undisclosed one. The company says permanent financing will come first. Until the terms are filed, the pro forma interest expense is an assumption, not a forecast, and the filing says so.
The purchase price allocation carries a second signal. Of $7,589,872 of consideration, $4,329,338 lands in intangibles and $2,201,784 in goodwill, so roughly six sevenths of what is being bought is contract, spectrum and customer value rather than hardware, even though Iridium’s constellation carries $1,927,018 of property, plant and equipment. That allocation drives future amortisation, and the pro forma cost of service revenue already rises by $24,087 for the half on that account.
A careful reader would watch three things. The first is the permanent financing, because every pro forma loss figure here is a function of the bridge. The second is the FCC docket, since section 310(d) consent is a discretionary public interest finding rather than a waiting period that simply expires, and Iridium’s authorisations include services relied on by aviation and maritime users. The third is Iridium’s own trading through the pendency: it drew $100.0 million on its revolving facility on July 1, 2026 to buy Aireon Holdings, adding a $183.4 million seller loan and $154.7 million of consolidated Aireon term debt, none of which is in the June 30 pro forma balance sheet. None of these filings establish that the deal will close, and the outside date runs to 2027.
What the documents say
Rocket Lab Corporation (Nasdaq: RKLB) filed the accounting for its pending purchase of Iridium Communications Inc. with the Securities and Exchange Commission on August 13, 2026, in a Form 8-K carrying unaudited pro forma condensed combined financial statements and a consent from its auditor. The filing states that the business has not yet been acquired and that the statements exist so the information can be incorporated into registration statements. The same day, the Long Beach company filed a Form S-4 covering the shares it would issue.
The pro formas are the first document to put a full price and a full balance sheet on a transaction announced on June 28, 2026. They are also the first to show what the combined company’s income statement would have looked like had the deal been financed as currently committed.
The price, as the accountants see it
Estimated aggregate consideration is $7,589,872, stated in thousands of dollars, built from four components. Iridium had 105,956,272 shares outstanding at June 30, 2026. Cash consideration of $27.00 a share gives $2,860,819. Stock consideration, using an exchange ratio of 0.3894 and a ten-day volume weighted average Rocket Lab price of $69.33 for the period ending August 7, 2026, gives 41,259,372 Rocket Lab shares worth $2,860,533. Assumed and cancelled equity awards add $93,799, split between $80,682 of restricted stock units, $7,674 of options and $5,443 of cash-settled appreciation rights. The fourth component is $1,774,721 for the pay-off of Iridium’s existing debt, which matches the term loan balance Iridium reported at June 30, 2026.
The preliminary purchase price allocation puts $4,329,338 into identifiable intangible assets and $1,927,018 into property, plant and equipment, offsets $1,125,351 of deferred tax liabilities among $1,317,635 of liabilities assumed, and arrives at identifiable net assets of $5,388,088 against total assets acquired of $6,705,723. Goodwill is $2,201,784. The filing states the allocation is preliminary and may change materially.
What the combined statements show
On a pro forma basis for the six months to June 30, 2026, total revenues would have been $878,708, combining Rocket Lab’s $434,414 with Iridium’s $444,294. Product revenue would have been $349,821 and service revenue $528,887, reversing the current mix at Rocket Lab, where product revenue dominates. Gross profit would have been $353,694 and the operating loss $106,090, against Rocket Lab’s own operating loss of $113,483 and Iridium’s operating income of $84,721.
The financing is what turns that into a larger loss. Rocket Lab has a commitment letter from Deutsche Bank AG New York Branch and Wells Fargo Bank, National Association for a 364-day senior secured bridge term loan facility of $3,600.0 million. The pro formas assume the bridge was drawn at closing and outstanding for the whole of each period, adding $141,357 of pro forma interest expense for the six months alone. Pro forma net loss for the half is $154,677, or $0.23 a share on 658,944 weighted average shares, against Rocket Lab’s own reported loss of $94,280 and Iridium’s net income of $31,273.
For the year ended December 31, 2025 the combined revenue line is $1,473,458, against Rocket Lab’s $601,799 and Iridium’s $871,659, and the pro forma net loss is $203,038. Rocket Lab notes it intends to replace the bridge with permanent financing before closing on terms that are not currently determinable, and that it is evaluating amendments to certain existing Iridium debt agreements which could reduce the bridge draw and the related interest.
The conditions that still have to clear
The June 8-K sets out the structure and the gates. Iridium merges with a Rocket Lab subsidiary and then, if the mix of cash and stock qualifies the deal as a tax-free reorganisation, into a second subsidiary. Iridium holders receive $27.00 in cash plus stock at an exchange ratio of 0.4000 if the Rocket Lab price is $67.50 or below, 0.2400 if it is $112.50 or above, and $27.00 divided by the price in between. Iridium stock would be delisted from Nasdaq after the first merger.
Closing requires a majority vote of Iridium shareholders, expiry of Hart-Scott-Rodino waiting periods, clearances under specified foreign investment and satellite laws, effectiveness of the S-4, approval of the new Rocket Lab shares for listing, and consent of the Federal Communications Commission to the transfer of control of Iridium telecommunications authorisations. That last condition rests on 47 U.S.C. 310(d), which bars transfer of a station licence or of control of the company holding it except on application to the Commission and a finding that the public interest, convenience, and necessity will be served. Either side may walk if the deal has not closed by June 28, 2027, a date extendable to September 28, 2027 and then December 28, 2027. Iridium owes a termination fee of $223.62 million in specified circumstances, including terminating to accept a superior proposal.
