The 43% Customer Bloom Is Related ToThin moat
Bloom Energy (BE) — moat facet
The largest and fastest-growing source of Bloom's revenue is a party it is financially connected to, which is a market test only in part.
The single most striking line in Bloom's filings is that its largest customer in 2025 — approximately 43% of total revenue — is a related party1. The same counterparty accounted for roughly 41% of accounts receivable.
Related-party revenue is common in this industry and entirely legitimate: strategic partners who invest in a manufacturer and then distribute its product in a region are a standard structure, particularly for a company that needed capital and market access simultaneously. It is also less informative than arm's-length revenue. When a counterparty is both an investor and the largest buyer, the price and the volume are partly a negotiated relationship rather than a pure market test of demand.
The trajectory sharpens the point. This relationship went from being one of two customers at 37% in 2023, through a year at 23%, to 43% in 2025. In the June 2026 quarter it fell to about 21% of revenue, behind a customer that is not related at 44%, and across the first half that unrelated customer alone was about 73%.2 For a company whose central investment question is whether demand for its product is real and durable, having the largest and fastest-growing single source of revenue be a related party is a genuine analytical problem.
Watch the related-party percentage in each annual filing. Falling while total revenue grows would mean independent demand is taking over, which is the single most important thing that could happen to the quality of Bloom's revenue.
The related-party relationship went from one of two customers at 37% in 2023, through 23% in 2024, to 43% in 2025 — the largest and fastest-growing source of revenue, and the one that is least a market test. For a company whose central question is whether demand is real and durable, that is an analytical problem rather than a governance one.
The same counterparty was about 41% of accounts receivable. It went from one of two customers at 37% in 2023, through 23% in 2024, to 43% in 2025. Related-party revenue is legitimate and is a market test only in part. Watch the percentage falling while total revenue grows.
