SB Energy's $439B backlog: how an AI data-center IPO prices a campus that isn't built

IPO Overview and Transaction Parameters

SB Energy filed its S‑1 registration statement on September 1 2026, seeking to list on the Nasdaq Global Select Market and Nasdaq Texas under the ticker SBE. The company aims to raise at least $5 billion, with market commentary suggesting a valuation target of roughly $50 billion. Pricing is expected in the week of September 21 2026, following the IPO filing on September 4.

Backlog Composition and Near‑Term Revenue Profile

The enterprise reports a $439 billion contracted backlog, heavily weighted toward data‑center projects ($430 billion) and a smaller power segment ($10 billion). The backlog is back‑loaded: only about $1 billion is projected to convert to revenue within the next 24 months, while roughly $357 billion lies beyond year 8. The weighted‑average remaining contract term is approximately 19.6 years for data‑center agreements and 16.6 years for power contracts.

Current Operations and Capacity Build‑Out

No data‑center capacity is presently in operation. The company has contracted or is constructing 8.8 GW‑IT of data‑center capacity, anchored by two flagship sites. The PORTS‑Pike campus in Pike County, Ohio—repurposed from a former DOE uranium‑enrichment facility—features 17 buildings leased to OpenAI for a total of roughly 8 GW‑IT, with the first 800 MW anticipated to be online in 2028 and the full build‑out extending through 2032. A secondary site in Milam County, Texas, delivering 753 MW‑IT, is slated for service readiness in 2028.

Financial Snapshot Through H1 2026

First‑half‑2026 revenue reached $138.7 million, reflecting a 66.4 % year‑over‑year increase. The same period saw a net loss of $3.21 billion, widening sharply from a loss of $215.5 million in the prior year.

Strategic Tenant and Investor Dynamics

OpenAI functions as both the principal tenant and a strategic equity investor. The AI pioneer has committed $500 million in equity, while its 20‑year lease agreements secure roughly 8 GW‑IT of data‑center capacity. OpenAI’s warrants were initially valued at $3.6 billion in January and rose to an estimated $5.5 billion by June 30, vesting in stages tied to post‑IPO valuation milestones. The S‑1 filing notes that SB Energy is substantially dependent on OpenAI in these dual roles, and the agreement gives OpenAI a board‑designated right should its stake exceed 5 %.

Technology Partner Guarantees and Financial Backstops

Nvidia is linked to the transaction with approximately $3 billion in commitments, comprising a $1.5 billion private placement at the IPO price and a $1.5 billion prepaid forward component. Nvidia will serve as the exclusive chip supplier to the Ohio site and provides a guarantee of up to $105 billion on the OpenAI lease obligations, acting as a backstop for lease payments rather than a direct investment.

Valuation Mechanics: Reconciling High Multiple with Low Near‑Term Revenue

The projected $50 billion valuation represents roughly 360 times the H1 2026 revenue run‑rate, a multiple that appears disconnected from immediate earnings but aligns with the long‑dated, high‑value contract portfolio. The valuation framework incorporates three key elements: (1) the sheer scale of contracted backlog, which embeds future cash flows extending beyond two decades; (2) the credit quality of the tenant, reinforced by OpenAI’s equity stake and contingent‑value warrants; and (3) the guarantee structure provided by Nvidia, which caps potential lease payment defaults at a level comparable to the contract aggregate. When discounted at rates appropriate for long‑duration infrastructure assets, the present value of the backlog can substantively support a multi‑billion‑dollar equity valuation despite modest current earnings.

Governance and Ownership Structure

SoftBank remains the controlling shareholder, ensuring that SB Energy will continue as a controlled entity post‑IPO. The governance framework, as disclosed in the S‑1 filing, reflects SoftBank’s ability to influence strategic decisions while permitting public investors to participate in the capital structure.

Risk Considerations for Potential Stakeholders

The concentration of revenue and equity exposure around a single tenant introduces reliance risk, magnified by the long‑term nature of the contracts. While the Nvidia guarantee mitigates lease‑payment risk, the company’s financial performance remains highly contingent on OpenAI’s operational health and its ability to meet lease obligations over the next two decades. Additionally, the substantial net loss underscores the capital‑intensive nature of building out data‑center capacity before revenue generation commences.

Conclusion

SB Energy’s IPO presents a case where a pre‑IPO valuation substantially exceeds current revenue, justified by a massive, multi‑decade backlog and fortified by strategic tenant equity and third‑party guarantees. The structure illustrates how long‑dated, high‑value contracts can underpin equity valuations far ahead of near‑term earnings.
