Do not judge an AI company’s financial risk from the debt line on its balance sheet. Build a complete schedule of borrowings, leases, guarantees, convertibles and maturities; subtract only liquid cash and near-cash investments; then test whether recurring operating cash can fund interest, principal, capital spending and working capital before the next refinancing date. For loss-making companies, cash burn and runway matter more than conventional interest-coverage ratios.
The process below uses public filings to answer the questions that determine downside risk: how much the company really owes, whether operations can service it, how long liquidity lasts after AI infrastructure spending, and whether new debt or share issuance is likely.

What “debt” means for an AI company
Debt is a schedule of contractual claims, not one balance-sheet number. Start with funded borrowings, but also capture obligations that can consume cash or rank ahead of shareholders:
- Current and long-term bank loans, notes and bonds.
- Convertible notes, including principal, interest, conversion price and any investor put or company call.
- Secured facilities and the assets pledged as collateral.
- Operating and finance lease liabilities for data centers, offices, equipment and vehicles.
- Guarantees, letters of credit, purchase commitments and other off-balance-sheet support.
- Unused revolvers and the conditions under which they can be drawn.
- Principal and interest due in the next 12 months and in each later year.
Gross debt shows the claims creditors hold. Net debt subtracts cash and genuinely liquid short-term investments, but it is not a complete solvency measure: some cash is restricted, needed for payroll or customer funds, or held in jurisdictions where moving it is costly. A company with more gross debt can be safer than a smaller borrower if it generates durable operating cash, has long maturities and holds ample unrestricted liquidity.
#1 Best Overall
Start with the latest filings
Use the most recent annual report (Form 10-K for a US issuer) and quarterly report (Form 10-Q), then reconcile the numbers to the notes. Read in this order:
- Balance sheet: identify cash, short-term investments, current debt, long-term debt and lease liabilities.
- Statement of cash flows: record cash from operations, capital expenditures and financing inflows or repayments.
- Management’s discussion and analysis: note explanations for changing liquidity, debt, working capital and capital spending.
- Liquidity section: look for management’s stated sources and uses of cash, revolver availability and financing plans.
- Debt footnote: extract every instrument’s principal, rate, maturity, security, covenant and conversion terms.
- Lease note: capture minimum payments and the portion due within 12 months.
- Commitments and contingencies: include purchase obligations, guarantees, litigation exposure and data-center or power commitments.
- Risk factors and going-concern disclosures: identify refinancing, covenant, customer-concentration and funding risks.
Quarterly filings can omit detail that appears in the annual report, so carry forward the full annual debt schedule and update it for new issuance, repayments, conversions and foreign-exchange effects.
Build a debt and liquidity table
Put every claim in one worksheet. A useful layout separates accounting classification from the cash date that matters to an investor.
| Item | What to record | Why it matters |
|---|---|---|
| Current borrowings | Principal due within 12 months, rate and security | Immediate cash requirement and refinancing risk |
| Long-term borrowings | Principal, maturity year, fixed or floating rate | Duration, interest sensitivity and maturity wall |
| Convertible notes | Coupon, conversion price, settlement choice, puts and calls | Potential dilution or cash repayment |
| Lease liabilities | Total minimum payments and next-12-month amount | Fixed charges that can compete with debt service |
| Guarantees and commitments | Maximum exposure, timing and conditions | Hidden or contingent claims |
| Liquidity | Unrestricted cash, near-cash investments and undrawn committed credit | Resources available before new financing |
Then calculate net debt = funded debt + finance leases − unrestricted cash − liquid short-term investments. Show leases separately as well; combining them with bonds can obscure how much is legally secured against specific assets.
Illustration: Tesla’s reported 2024 position
Tesla’s 2024 Form 10-K reports $7.91 billion of aggregate indebtedness, including $2.35 billion current; $7.05 billion of minimum lease payments, including $1.19 billion due in the next 12 months; $16.14 billion of cash and cash equivalents; $20.42 billion of short-term investments; and $5.00 billion of unused committed credit. These are figures for December 31, 2024, and should not be treated as a current balance after subsequent filings. The example shows why a debt-only glance misses leases, liquid investments and committed backup credit.
Test whether operations can service the claims
For a profitable, established issuer, calculate:
- Interest coverage: EBIT (or operating income) ÷ interest expense.
- Cash interest coverage: cash flow from operations before interest and taxes ÷ cash interest paid, when the filing provides comparable figures.
- Debt-to-operating-cash-flow: gross or net debt ÷ a normalized, recurring operating cash-flow measure.
- Fixed-charge coverage: cash available for fixed charges ÷ interest, principal, lease payments and other mandatory charges.
Use a normalized period rather than one quarter distorted by a tax refund, working-capital release or customer prepayment. Reconcile EBIT-based ratios to cash because accounting earnings can include non-cash compensation, depreciation and remeasurement gains.
For a loss-making AI developer, interest coverage may be meaningless or negative. Focus on cash from operations, cash interest, scheduled principal, lease payments and capital expenditures. Reliance’s 2024 Form 10-K warns that “a significant portion of our cash flow from operations must be dedicated to the payment of interest and principal on our debt,” reducing funds for operations, dividends, repurchases and other purposes. Treat that dynamic as a loss of strategic flexibility, not merely a ratio.

A transparent first-pass runway is:
Runway in years = (unrestricted cash + liquid short-term investments) ÷ annualized negative cash from operations.
Use the latest four quarters when available, and show the result both before and after capital expenditures. If cash from operations is positive only because of temporary working-capital inflows, normalize it rather than claiming infinite runway.
Adjust the denominator for real cash needs
- Add contractual interest and principal that are not already reflected in the operating-cash figure.
- Add lease payments and unavoidable minimum purchase commitments.
- Include sustaining and expansion capex for GPUs, servers, networking, data centers, power and cooling.
- Model working-capital growth when revenue scales faster than collections or suppliers require deposits.
- Remove restricted cash and investments that cannot fund the parent company.
Run downside cases
At minimum, model slower bookings, lower gross margin, delayed customer acceptance, higher GPU prices, power-cost inflation, a two-year capex delay in revenue, and no access to the refinancing market. Also test a covenant breach: a revolver that is technically undrawn may become unavailable when leverage, liquidity or borrowing-base tests fail.
Rigetti’s 2025 Form 10-K reports a $216.2 million net loss in 2025, a $201.0 million net loss in 2024 and a $771.0 million accumulated deficit at December 31, 2025. Those figures do not by themselves determine insolvency, but they justify a runway model that assumes additional equity, debt, strategic financing or project delays may be required.

List every maturity by date, not just the total balance. Compare the date with your stressed runway and the time needed to raise capital. A company that reaches a large maturity before its cash trough is exposed even if its long-term business plan is attractive.
| Term | Questions to answer |
|---|---|
| Maturity | What principal is due in each of the next five years and thereafter? |
| Interest rate | Fixed coupon, benchmark plus spread, reset frequency and hedges? |
| Security | Which data centers, receivables, intellectual property or subsidiaries are pledged? |
| Guarantees | Which parent or subsidiary guarantees repayment? |
| Covenants | Minimum liquidity, leverage, interest coverage, liens, investments or restricted payments? |
| Conversion | Conversion price, share settlement, capped calls, dilution and investor puts? |
| Defaults | Cross-default, change-of-control, acceleration and grace periods? |
Floating-rate debt creates a direct sensitivity to benchmark rates. Secured debt can be cheaper but gives lenders priority over assets that may be essential to future operations. Unsecured notes may preserve asset flexibility but can carry higher coupons. A revolver is useful only when it is committed, undrawn capacity remains after covenant tests, and the lenders are not entitled to cancel it for a material adverse event.
Alphabet’s 2024 annual report lists $11.9 billion of senior unsecured notes, $197 million of short-term future interest payments and $3.4 billion of long-term future interest payments. The interest schedule illustrates why principal alone understates the cash cost of a debt program.
Read going-concern and financing-dependence language literally
Auditors and management use specific language when available liquidity and expected cash flows may not cover obligations. A going-concern warning is not a prediction of bankruptcy, but it is a high-priority signal to model dilution, distressed borrowing, asset sales and delayed projects.

Clear out junk files and repair common Windows errorsFree Scan →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Datavault AI’s 2024 Form 10-K states that “the Company’s recurring losses from operations, a net capital deficiency, available cash and cash used in operations raise substantial doubt about its ability to continue as a going concern.” That statement should move the company into a scenario where new financing is a condition of continuing operations, rather than a discretionary growth choice.
Rigetti says it may need additional funds through equity or debt financing, strategic collaborations or other transactions. For an investor, each route has a different cost: equity can dilute existing holders; secured debt can encumber assets; convertibles can defer dilution while creating a future share or cash obligation; and strategic transactions can transfer economics or control.
Put AI capital spending in context
AI infrastructure can consume cash well before utilization and pricing mature. Separate:
- Growth capex: new accelerators, clusters, data halls and power capacity intended to support future demand.
- Sustaining capex: replacement and maintenance required to keep existing capacity productive.
- Committed infrastructure: leases, take-or-pay power, colocation and equipment orders that may remain payable even if demand weakens.
Compare capex with operating cash flow and contracted or highly visible demand, not with total-addressable-market claims. Ask how quickly each dollar of capacity can generate cash, who bears utilization risk, and whether customers have termination rights.

The Bank for International Settlements bulletin Financing the AI boom: from cash flows to debt reports that AI firms historically used less debt than other firms, but that higher leverage can amplify shocks if expected returns fail to materialize. It also reports AI-related direct loans rising from close to 0% to about 4% in 2025. The implication is not that debt is automatically unsafe; it is that a rapidly changing financing mix makes maturity, collateral and demand assumptions more important.

Compare AI companies on the same decision axes
Use a common worksheet so a large, profitable platform is not judged by the same lens as a pre-revenue hardware developer.
| Axis | Measure | Interpretation |
|---|---|---|
| Net debt | Debt and leases less unrestricted liquidity | Absolute burden after immediately available funds |
| Debt / operating cash flow | Use normalized recurring cash flow | Repayment capacity; avoid using a temporary cash spike |
| Interest and fixed-charge coverage | Operating income or cash available ÷ mandatory charges | Ability to absorb earnings or rate shocks |
| Runway after capex | Liquidity ÷ stressed cash burn including AI infrastructure | Time before external funding is required |
| Next-12-month maturities | Principal, interest and lease payments due | Near-term refinancing pressure |
| Rate and covenant exposure | Floating-rate share, resets and headroom | Sensitivity to rates and operating deterioration |
| Secured versus unsecured claims | Collateral and priority | What shareholders may lose in distress |
| Dilution or convertibility | Shares issuable, conversion prices and puts | Potential ownership transfer or cash settlement |
| Revenue quality | Customer concentration, backlog and contract terms | Reliability of the cash flow supporting debt |
Rank the result by refinancing risk, not by gross debt alone. Long maturities, large liquid reserves and recurring cash generation can offset a higher nominal balance; short maturities, concentrated customers and aggressive capex can make a smaller balance dangerous.
A practical filing checklist
- Download the latest 10-K and 10-Q and note their filing dates.
- Copy every debt, lease, guarantee and commitment into a spreadsheet.
- Mark unrestricted cash, liquid investments, restricted cash and undrawn committed credit separately.
- Build a year-by-year maturity schedule through the longest instrument.
- Calculate gross debt, net debt, debt-to-operating-cash-flow and interest coverage where meaningful.
- Calculate runway using recent operating cash burn, then recalculate after capex, leases and mandatory debt service.
- Stress revenue, margin, capex, rates, working capital and refinancing access.
- Read covenants, collateral, guarantees, conversion provisions and cross-default clauses.
- Search the filing for “going concern,” “substantial doubt,” “additional financing,” “liquidity,” “covenant” and “maturity.”
- Compare the stressed cash trough with each maturity date and decide whether new capital is optional or necessary.
Common mistakes that produce false comfort
- Using gross debt without liquidity: cash and short-term investments can materially change near-term risk, but only if they are unrestricted and liquid.
- Netting every investment: strategic, restricted or illiquid investments cannot reliably pay tomorrow’s bondholder.
- Ignoring leases: data-center and equipment leases are fixed claims even when they are not presented as borrowings.
- Annualizing one strong quarter: customer prepayments and working-capital releases can overstate sustainable cash generation.
- Assuming a revolver will be renewed: availability depends on commitment terms, covenants and lender health.
- Calling convertibles “free”: they require cash repayment if conversion does not occur and can dilute shareholders if it does.
- Comparing EBITDA alone: AI companies can report attractive adjusted earnings while spending heavily on GPUs and facilities.
- Reading the maturity wall without the business cycle: a maturity due during a demand slowdown is more dangerous than the same maturity during a cash-rich period.
- Treating a going-concern paragraph as boilerplate: it changes the financing scenario from optional growth capital to a potential operating necessity.
How to turn the analysis into an investment decision
Set explicit conditions before buying. For example, require that stressed liquidity covers the next 12 months of principal, interest, leases and sustaining capex; require covenant headroom after a realistic revenue decline; and assign a dilution penalty when management’s plan depends on issuing shares or convertibles. If a company fails those tests, the decision is not automatically “sell,” but the price must compensate for refinancing, dilution and execution risk that a simple debt-to-equity ratio hides.
Update the worksheet after every quarterly filing, debt issuance, large equipment order, acquisition, rating action or material customer loss. Debt risk changes faster than the annual report, especially while AI infrastructure spending is accelerating.
