The temporary-power company's registration statement discloses a data-center revenue share large enough to change which companies it should be priced against.
FINANCIALMARKETS.COM | AFTERNOON EDITION
Aggreko's registration statement discloses that AI data centers account for approximately 19% of the company's sales, a disclosure that arrives while the offering still has no announced pricing or listing date.
The figure is the most useful thing in the filing for anyone trying to value the business, because it changes the comparison set. A temporary-power and rental-generation business is conventionally priced against industrial equipment rental, a cyclical, competitively fragmented, mid-single-digit-growth category. A business deriving nearly a fifth of revenue from data-center power is being asked to be valued at least partly against AI infrastructure, where the multiples are entirely different.
The bull case is that this is a real and durable revenue mix shift. Data centers need bridging power during construction and commissioning, grid interconnection queues are long, and that is precisely the gap temporary generation fills. If the buildout continues at anything like its current pace, the 19% grows.
The bear case is that 19% from one end market is concentration, not diversification, and that temporary power is by definition temporary. Revenue tied to construction and commissioning phases is revenue that ends when the facility comes online, unless new facilities keep starting. The disclosure establishes the current share. It does not establish contract duration, renewal rates, or how much of that 19% is recurring versus project-based, and those are the three things that determine whether the exposure deserves an infrastructure multiple or a rental multiple.
Neither a price range nor a listing date has been set. Pricing is where the market will tell Aggreko which comparison set it accepts, and the terms sheet, when it appears, will be more informative about that than the S-1 was.
