Key Notes
- Microsoft priced $25 billion of senior unsecured notes on October 29, with closing scheduled for November 4.
- The offering includes $23 billion of fixed-rate debt and $2 billion of floating-rate notes, with maturities through 2066.
- Proceeds can fund capital spending and other corporate uses as Microsoft expands its cloud and AI infrastructure.
Microsoft Corp. (NASDAQ: MSFT) has priced a $25 billion bond offering, turning to debt investors as the cost of expanding its cloud and artificial-intelligence infrastructure consumes a growing share of operating cash flow.
The senior unsecured notes were priced on October 29, with closing scheduled for November 4, according to Microsoft’s announcement. The company has given itself broad discretion over the proceeds, including capital expenditure, acquisitions, share repurchases and repayment of existing debt.
The financing therefore adds resources for its investment program without earmarking the entire $25 billion for AI. It also arrives while Microsoft remains substantially cash-generative, rather than reporting an operating cash shortfall.
The Sale Spreads Borrowing Across Four Decades
Microsoft divided the offering into 10 tranches: $23 billion of fixed-rate debt and $2 billion of floating-rate notes. Maturities run from 2028 to 2066, spreading repayments rather than concentrating the full amount in one year.
Fixed coupons range from 4.85% on two-year notes to 6.35% on the 40-year tranche. The largest fixed-rate pieces are $4 billion due in 2036 at 5.55% and another $4 billion due in 2056 at 6.25%.
Using the announced principal amounts and coupons, the fixed-rate portion carries about $1.28 billion of annual coupon payments before considering the two floating-rate tranches. That is a calculation of contractual coupons, rather than a forecast of Microsoft’s reported interest expense or an estimate of its total financing cost.
For Microsoft, issuing across several maturities secures some funding well beyond the current construction cycle. The longer-dated notes also create interest obligations that will remain after today’s generation of AI equipment has been replaced.
AI Investment Takes a Larger Share of Cash Flow
Microsoft’s quarterly results explain the scale of that investment. Operating cash flow reached about $58 billion in the September quarter, while cash paid for property and equipment totaled $39.37 billion. Free cash flow was approximately $18.6 billion.
Revenue rose 19% to $92.28 billion, with Azure growing 48%. Microsoft is expanding capacity against an already large and growing cloud business, rather than borrowing solely against the prospect of future customers.
Even so, the cash left after infrastructure purchases fell from roughly $25.7 billion a year earlier. Shareholders are receiving faster cloud growth while a larger portion of the cash generated by the business goes back into expansion, as we previously reported.
That creates a financing choice rather than a simple funding emergency. Debt can preserve flexibility for other uses of cash, including distributions to shareholders, while increasing the amount that must be serviced in future years.
Management Expects Spending to Accelerate
On the earnings call, Chief Financial Officer Amy Hood forecast more than $50 billion of capital expenditure in the December quarter and approximately $170 billion for calendar 2026. The company expects investment to accelerate in the second half of fiscal 2027 as equipment and delayed third-party capacity arrive.
The spending measures require care. September-quarter capex including finance leases was $45.2 billion, while cash additions to property and equipment were $39.37 billion. Finance leases and the timing of cash payments mean those figures measure different aspects of investment.
Some capacity deliveries slipped out of the quarter, contributing to a lower-than-expected capex figure. That shortfall also pressured specialist cloud providers, as we reported. It did not amount to a wholesale cancellation of Microsoft’s construction plans.
The Stock and the Debt Face Different Tests
Microsoft shares closed Wednesday at $555.80, up 6.68%, according to CNBC’s quote data, as the broader market rallied after the midterm elections. That session’s gain followed the bond pricing by several days and should not be treated as a direct measure of demand for the notes.
Equity investors are weighing the earnings potential of added cloud capacity. Bondholders receive a different bargain: scheduled interest and repayment, with no participation in any increase in the share price.
Microsoft’s existing cash generation gives the borrowing a substantial business behind it. The question for shareholders is how productively the next wave of infrastructure spending turns into revenue and cash after those new interest bills are paid.
