Danaher Raises €3 Billion in Senior Notes to Finance Masimo Deal

Context Danaher Corp. (NYSE: DHR) announced a multi‑tranche note offering to fund its pending purchase of Masimo Corp. The company’s market cap sits near $180 bn, and the issuance adds a new layer of debt to its balance sheet.

Key Facts - The offering comprises a €500 m floating‑rate tranche due April 29, 2028 and three fixed‑rate tranches: €750 m at 3.25% due 2030, €750 m at 3.625% due 2034, and €1 bn at 4.0% due 2038. - Floating‑rate notes pay interest quarterly, starting July 29, 2026; fixed‑rate notes pay annually on April 29, beginning 2027. - Each fixed‑rate series can be called by Danaher on its “Par Call Date” (one month before the 2030 maturity, three months before the 2034 and 2038 maturities) at the greater of 100% of principal or a discounted present‑value calculation plus a small spread (10‑15 basis points). - If the Masimo merger is not completed by November 16, 2026, Danaher must redeem all fixed‑rate notes in full at 101% of principal plus accrued interest. - A change‑of‑control event also triggers a 101% redemption right for noteholders.

What It Means The €3 bn raise provides cash for the Masimo transaction while locking in relatively low coupon rates—3.25% to 4.0%—reflecting strong investor demand for Danaher debt. The floating‑rate tranche offers protection against rising rates, as its coupon resets quarterly.

The mandatory redemption clause creates a built‑in penalty if the acquisition stalls, effectively increasing Danaher’s cost of capital should the deal fall through. Investors will watch the November deadline closely; a missed deadline would force Danaher to repay €2.5 bn of fixed‑rate notes at a premium, potentially straining liquidity.

Market reaction was muted, with DHR shares up 0.4% after the announcement, while the new notes priced at the indicated yields. The issuance brings Danaher’s total long‑term debt to roughly €30 bn, a level comparable to peers in the industrial conglomerate space.

Looking Ahead The next catalyst is the November 16, 2026 merger deadline. Confirmation of the Masimo deal will lock in the financing; any delay or termination will trigger the 101% redemption and could reshape Danaher’s capital structure.
