Contracted operation and maintenance on every Energy Server deployed, on terms Bloom says run 5 to 20 years with roughly full attach on product. It is the annuity under the hardware and the one line whose margin genuinely turned: gross margin went from -26% in 2023 Q1 to +18.65% in the basis quarter as stack life improved and the fleet aged into cheaper service. It grows with the installed base rather than the quarter's shipments, which is why it compounds slowly while product triples. The fleet is measured in kilowatts and the fee in dollars per kilowatt-month.

Subscribers 1.8M 7.2% of a 25.0M addressable base 1.8 GW of installed fleet, in kW. Bloom does not disclose it; back-solved so the fee lands at a credible O&M rate.
Addressable subscribers 25.0M the S-curve ceiling 25 GW, the supply-chain visibility Bloom cites. The serviced fleet cannot exceed what it ever ships.
Net adds 220K/qtr ramping toward 600K/qtr, throttled as the base approaches the TAM 220 MW a quarter joins the serviced fleet against ~312 MW shipped — commissioning lags acceptance.
Net-add ceiling 600K/qtr what supply can deliver at full rate 600 MW a quarter, roughly the 2 GW annual line running full out and all of it entering service.
ARPU $12.78/mo drifting +0.3% per quarter, floor $10.00 $12.78 per kW-month reproduces Q2'26 service revenue on the assumed fleet; about 5.1% of capital cost a year.
Non-subscriber revenue $0/qtr growing 0.0% per quarter Bloom reports no service revenue outside the contracted O&M book, so there is nothing to carry here.

Assumptions & reasoning

  • This is the line the $14B 'service backlog' points at, and it is also the line that most overstates the backlog: the 10-K says O&M terms are 'subject to termination for convenience on an annual basis', so most of that figure is not an enforceable obligation.
  • Service revenue grew 26.8% year over year in the basis quarter while product grew 215%. Modelling service off the quarter's shipments rather than the cumulative fleet would overstate it by several multiples.
  • The installed-fleet megawatt figure is the weakest number in this brief. It is assumed, and the ARPU it produces ($153k per MW per year, about 5.1% of an assumed $3.0M/MW capital cost) is a cross-check that makes it credible rather than a disclosure.
