Digital Realty 8-K: €1 Billion 5.125% Euro Notes Sold Under Reg S

The news

Digital Realty Trust, Inc. and its operating partnership, Digital Realty Trust, L.P., filed a Form 8-K on Oct. 9, 2026 reporting that Digital Euro Finco, LLC, an indirect finance subsidiary, issued and sold €1,000,000,000 of 5.125% Guaranteed Notes due 2036. The notes were sold outside the United States in reliance on Regulation S (Reg S), have not been registered under the Securities Act and cannot be offered or sold in the U.S. or to U.S. persons without registration or an exemption.

The notes are senior unsecured obligations of the finance subsidiary and are fully and unconditionally guaranteed by both the REIT and the operating partnership. They mature on Oct. 9, 2036, with interest paid annually on Oct. 9 starting in 2027. The initial purchasers paid 99.289% of principal. Net proceeds were about €985.8 million after managers’ discounts and estimated expenses.

The filing sits under two items: Item 1.01, entry into a material definitive agreement, and Item 2.03, creation of a direct financial obligation. The governing indenture is dated Oct. 9 and names Deutsche Trustee Company Limited as trustee, with Deutsche Bank entities as paying agent, transfer agent and registrar.

Our analysis

This is a plain financing disclosure. The price and coupon are the details most readers will look for. The initial purchasers paid less than par, though the filing does not state the reoffer price to investors or a yield. The gap between the 99.289% purchase price and the €985.8 million of net proceeds implies roughly €7 million in discounts and expenses, which is our arithmetic and not a figure the filing states.

The use of proceeds is the distinctive feature. Digital Realty says it intends to allocate an amount equal to the net proceeds to finance or refinance new or existing eligible green projects, a category the filing defines to include renewable energy, energy efficiency, pollution prevention, green building and several others. Until allocation, the money may repay borrowings under the operating partnership’s global revolving credit facilities, fund acquisitions or development, or be held in interest-bearing accounts consistent with REIT status.

Structure matters for a Reg S deal. Selling to non-U.S. investors avoids the cost of an SEC registration, while the parent and operating partnership guarantees let investors rely on the credit of the whole group. The indenture includes limits on additional indebtedness and a requirement to keep a pool of unencumbered assets. The notes are redeemable at par plus a make-whole premium, with the premium falling away within 90 days of maturity, and the issuer will pay additional amounts so that non-U.S. holders receive payments free of U.S. withholding, subject to exceptions.

A euro bond with a green use-of-proceeds clause is a financing disclosure, not a deal signal.

Room for disagreement

Not everyone accepts the green label as a meaningful constraint. The filing allows proceeds to sit temporarily in revolver repayments or general corporate uses before they reach eligible projects, so the earmark is an allocation commitment rather than a ring-fence. The 8-K also does not say which projects will be funded or how allocation will be reported.

A second view is that the financing says little about corporate strategy. The filing does not describe the euro proceeds as tied to any acquisition or other transaction, and its general-purpose uses are broad.

What to watch

• Digital Realty’s next quarterly report, which should show how the euro notes affect debt maturities and interest expense.
• Any allocation reporting on eligible green projects.
• Whether the company returns to the euro market or to other Reg S offerings.
