The pending acquisition: an operating LEO constellation with globally harmonised L-band spectrum, 2.6 million billable subscribers and a recurring services base. It is the recurring-revenue layer Rocket Lab does not otherwise have, and it is not owned yet.

Assumptions & reasoning
- Iridium is not owned. The line carries zero across every historical quarter and starts four quarters out, which is the mid-2027 close both companies have guided to.
- The share count and net cash in this model are already pro-forma for the deal, so switching this vertical off would leave the valuation carrying the cost of an acquisition it never made.
- Iridium closed its own Aireon acquisition on 2 July 2026, after the quarter this base reads, so the starting revenue understates what Rocket Lab would actually be buying.
- The subscriber base is held flat through the four delay quarters because the engine starts a delayed line from its stated base - roughly 36,000 adds a quarter of understatement.
- Rocket Lab's preliminary purchase price allocation marks the L-band spectrum at $3.3155bn - 43.7% of the $7.59bn consideration and 1.72x the $1.927bn it assigns to the constellation - but a revenue-times-margin line has nowhere to put a non-earning asset, so this model still carries none of it and fair value excludes it.
- The margins here are Iridium management's own: its standalone forecast filed with the merger registration statement implies 55.5% adjusted EBITDA in 2027 rising to 64.2% by 2035, against the 45% to 50% this model assumed before the forecast was public.
- That same forecast puts unlevered free cash flow at $(21)M in 2031 on constellation replacement capital expenditure, which lands at the end of this horizon - so the exit multiple is struck on revenue just ahead of a capex step the capital intensity here does not represent.
