Oracle Stock: When a $638 Billion Backlog Becomes a Balance-Sheet Problem

Introduction

Oracle closed fiscal 2026 with a number that stopped Wall Street cold: $638 billion in remaining performance obligations, up $85 billion in a single quarter (Oracle Investor Relations, 2026). It's the largest contracted order book any software company has reported. It's also, paradoxically, part of why ORCL stock has fallen roughly 55% from its September 2025 high near $325 to around $144 in late August 2026 (stockanalysis.com, Aug 24, 2026).

Oracle's business is accelerating. Its economics are getting more complicated. Both are true at once — and that tension, not a lack of demand, is driving Oracle valuation right now.

Key Takeaways

• Oracle's backlog (RPO) hit a record $638 billion, up $85 billion in one quarter — unmatched visibility, but not cash in hand.
• Oracle expects to raise roughly $40 billion in debt and equity in fiscal 2027 to build the capacity behind those contracts (Oracle IR, 2026).
• Free cash flow ran negative $23.7 billion in fiscal 2026; S&P projects that deficit could widen toward $42 billion in fiscal 2027 (S&P Global Ratings, Jul 9, 2026).
• S&P downgraded Oracle to BBB- on July 9, 2026 — one notch above junk — citing leverage and heavy concentration in OpenAI.

The Backlog: What $638 Billion in RPO Actually Means

RPO — remaining performance obligations — is the value of contracts customers have already signed that Oracle hasn't yet recognized as revenue. It's a confirmed order book: the customer is committed, the money isn't in the bank, and revenue shows up over the contract's life as Oracle delivers.

For a company built on multi-year cloud deals, that's an unusually clean window into the future. The $638 billion backlog is the strongest evidence that Oracle AI demand is real, not a story management is telling to justify spending. The problem is what comes next.

Revenue Conversion vs. Capex: A Backlog Isn't Cash

A signed contract isn't a finished data center. Before Oracle can convert that backlog into recognized revenue, it has to build the physical capacity — GPUs, power, cooling, real estate — customers are waiting to use. That's the friction at the center of this story: the bigger the backlog gets, the more Oracle must spend upfront, before a dollar of it becomes cash flow.

Oracle spent $55.7 billion on capex in fiscal 2026, and S&P now forecasts fiscal 2027 capex could reach $90–95 billion as the company races to keep pace with contracted demand (S&P Global Ratings, Jul 9, 2026). That's a company building a hyperscaler's worth of infrastructure on a compressed timeline, because customers are already waiting on the other end of those contracts.

Debt & Free Cash Flow: The Bill for the Buildout

Building at that pace requires capital Oracle doesn't generate internally. It raised $43 billion in debt and $5 billion in equity in fiscal 2026, and expects to raise roughly $40 billion more in fiscal 2027 (Oracle Investor Relations, 2026). Oracle AI spending isn't being funded out of operating cash flow — it's being funded on the balance sheet.

That shift shows in the numbers. Fiscal 2026 free cash flow came in negative $23.7 billion, as capex outran $32 billion in operating cash flow, and S&P projects the fiscal 2027 gap could widen toward $42 billion (S&P Global Ratings, Jul 9, 2026). Oracle now carries roughly $160–167 billion in total debt, and rating agencies have noticed: S&P cut its issuer rating to BBB- on July 9, 2026 — one notch above junk — flagging rising leverage and Oracle's concentration in OpenAI, which reportedly accounts for roughly half the backlog (S&P Global Ratings, Jul 9, 2026). Oracle debt is growing about as fast as Oracle's order book — a trade-off investors are now pricing directly.

Margins & the Multiple: Why the Stock Pulled Back Anyway

That debt carries a cost, and it lands on the income statement, not just the balance sheet. Rising interest expense and the depreciation load from new data-center assets both press down on operating margins, even as revenue accelerates — earnings reaching shareholders are increasingly diluted by the cost of financing the growth itself.

Oracle trades near 25x trailing earnings today, well off its highs — and that multiple doesn't look cheap once cash flow is being consumed by capex and interest rather than returned to shareholders. That's the real answer to why ORCL stock pulled back even as its backlog set a record: a multiple is a claim on future cash flow, and right now a large share of Oracle's cash flow is spent before it reaches the bottom line.

Any credible Oracle stock forecast has to hold two facts at once — the demand is real, and the financing is genuinely risky. Oracle isn't over-promising on AI. It's discovering that turning a $638 billion backlog into durable earnings is its own, harder problem, measured in billions of debt and years of buildout, not quarters.
