Rocket Lab's own merger accounting marks Iridium's satellite constellation and ground infrastructure at $1,927.0 million, and Iridium's filings put the programme that built it at approximately $3 billion. On 22 September, on camera, Peter Beck put a third number beside them: Rocket Lab could have done it, he said, for "around about 350 million" — a number he hedged in the same breath with "don't quote me on this."
Both ends of his comparison are filed documents, so the claim is checkable.
Iridium itemised its $3 billion, and satellites were three-quarters of it
The $3 billion is Iridium's own language, from its 2017 annual report: "We estimate the aggregate costs associated with the design, build and launch of Iridium NEXT and related infrastructure upgrades through 2018 to be approximately $3 billion." The 2018 report repeated it after completion.
The same filings say where it went. A primarily fixed-price development contract with Thales Alenia Space, signed in June 2010 for the design and manufacture of the satellites, carried a total price of approximately $2.3 billion. Launch came to $510.8 million — $448.9 million for seven Falcon 9 flights and $61.9 million for an eighth — less $29.8 million recovered from the German research centre GFZ, which shared one of them. The residual, ground segment included, is $3,000m − $2,300m − $510.8m + $29.8m = roughly $219 million.
Rocket Lab sells launch. Launch was $510.8m ÷ $3,000m = 17.0% of the programme.
Beck said "develop and deploy", which closes the satellites-only reading
The obvious defence is that he meant satellites, with Rocket Lab's rockets at cost. His words do not allow it. Iridium's $3 billion was "for them to develop and deploy," and he described "the timeframe to develop the satellite and put it on orbit" — the scope Iridium used for its own number.
Grant the defence anyway. Strike every launch dollar and $3,000m − $510.8m = $2,489.2m remains, against which $350 million is a 7.1x discount. Strike the ground segment too and the satellite contract alone is $2.3 billion, a 6.6x discount. Thales's contract works out at $2,300m ÷ 75 = $30.7 million for each satellite Iridium deployed; the napkin implies $350m ÷ 75 = $4.7 million each, launch included.
Denominators as disclosed; discounts are R40 arithmetic on the $350m claim
| Scope granted to the $350m | Denominator | Discount |
|---|---|---|
| Full programme, design through launch | $3,000.0M | 8.6x |
| Programme less every launch dollar | $2,489.2M | 7.1x |
| Satellite contract alone | $2,300.0M | 6.6x |
| Rocket Lab's mark on the same assets | $1,927.0M | 5.5x |
| Per satellite, 75 deployed | $30.7M each | 6.6x |
Denominators from Iridium's 2017 and 2018 annual reports and from the preliminary purchase price allocation in Exhibit 99.3 to Rocket Lab's 13 August 2026 current report. Rocket Lab's $1,927.0m mark is a fair value that equals Iridium's depreciated carrying amount, not original cost. The per-satellite line divides the Thales contract by the 75 satellites Iridium deployed; the napkin's equivalent is $4.7m each, launch included.
Whatever the saving is, satellite manufacturing has to supply it.
Rocket Lab's own replacement-cost range contains $1,927.0 million
In the pro forma filed on 13 August, which we read when it landed, Rocket Lab says how it valued the hardware: management "considered the operational status of the constellation, recent technical assessments, the specialized nature of the assets, and a replacement cost analysis to determine a preliminary range of fair value of these assets. The recorded balance represents a point within that range."
That balance is $1,927.0 million. Against the napkin, $1,927.0m − $350m = $1,577.0 million.
One caveat. The $1,927.0 million is also Iridium's carrying amount at 30 June — Rocket Lab's only purchase adjustment to property is $9.2 million of capitalised stock compensation, so fair value and depreciated book are the same line. Iridium carries its satellite system at $3,379.2 million of original cost against $2,195.7 million of accumulated depreciation on all its depreciable assets. Note (c) says a replacement-cost range exists and that $1.93 billion sits inside it.
Six weeks ago Beck told shareholders a constellation takes a decade
On the second-quarter call on 10 August, making the build-versus-buy case, Beck said: "It will take a decade or more to build out a constellation from scratch." In the clip he called five years plus typical and said Rocket Lab could "roll some stuff off our production line, 12 months or 24 months." August covers the business — subscribers, spectrum, distribution — and September the hardware, so the two are not flatly contradictory. Both are his, six weeks apart, pointing opposite ways on how hard the hardware is.
His case has real support. Iridium's price was struck in 2010 by a prime contractor on a development programme, mass-produced satellites have fallen in cost since, and Rocket Lab pays itself no launch margin. Grant all of it, and the claim still has to take a $30.7 million satellite to $4.7 million.
A low replacement cost for the asset you are buying is a convenient thing to say two days before the sellers vote. No document Rocket Lab has filed with the SEC contains "$350 million" or "back of the napkin."
A contracted price would settle it, and 2031 is where it would matter
If Rocket Lab bids, wins or books a constellation of this class near $350 million, the napkin was right. If its satellite work keeps pricing at prime-contractor levels, this stays a claim.
One year turns on it. Iridium's ten-year forecast, disclosed in the merger filing, drops unlevered free cash flow to $(21) million in 2031 on constellation replacement and never regains its 2030 level. A real $350 million rebuild would make that trough a rounding error. Nothing has contracted one.
Iridium's stockholders vote on 24 September at 8:30 a.m. Eastern.
Iridium's approximately $3 billion estimate for Iridium NEXT, the Thales Alenia Space contract price, the two SpaceX launch agreements, the GFZ recovery, the 75 satellites deployed and the satellite system's original cost are from Iridium's annual reports for 2017, 2018 and 2025. The purchase price allocation, note (c)'s replacement-cost language, the $9.2 million property adjustment and Iridium management's ten-year forecast are in Exhibit 99.3 to Rocket Lab's 13 August 2026 current report; the meeting date is from Iridium's 18 September current report. Beck's $350 million, his timeframes and his hedge are from a video clip posted to X on 22 September and appear in no Rocket Lab filing — a claim, not a cost. Every share, discount and per-satellite figure built on these is ours, as is the residual ground-segment line.
