Illumina Raises $300 Million in 4.95% Notes to Refinance 2026 Debt
The genomics company completed a public offering of three-year notes, with proceeds earmarked to repay bonds maturing next month.
Debt Refinancing Transaction
Illumina, Inc. completed a $300 million public offering of senior notes on August 17, 2026, according to an 8-K filing with the Securities and Exchange Commission. The notes carry a 4.950% coupon and mature on September 19, 2029 (8-K filing, 2026-08-17).
The genomics sequencing company plans to use the net proceeds from the offering, combined with cash on hand, to repay its existing 4.650% notes due September 9, 2026, which had $500 million in aggregate principal amount outstanding as of June 28, 2026 (8-K filing, 2026-08-17).
Note Terms and Structure
The notes were issued under an indenture originally dated March 12, 2021, with U.S. Bank Trust Company, National Association serving as trustee. Interest will accrue at 4.950% per annum, payable semi-annually on March 19 and September 19 of each year, beginning March 19, 2027 (8-K filing, 2026-08-17).
The notes are denominated in minimum increments of $2,000, with additional amounts in $1,000 multiples. They were registered on Form S-3 under file number 333-281921 and issued in book-entry form through The Depository Trust Company (8-K filing, 2026-08-17).
Redemption and Change of Control Provisions
Illumina retains the right to redeem the notes, in whole or in part, prior to August 19, 2029—designated as the "Par Call Date"—at a price equal to the greater of 100% of principal or the present value of remaining payments discounted at the Treasury Rate plus 10 basis points (8-K filing, 2026-08-17). On or after the Par Call Date, the company may redeem notes at par plus accrued interest.
The indenture includes change of control protections. If a "Change of Control Triggering Event" occurs and Illumina does not exercise its redemption right, the company must offer to repurchase notes at 101% of principal plus accrued interest (8-K filing, 2026-08-17).
Financial Context
The transaction represents a refinancing at a higher coupon rate—rising 30 basis points from 4.650% to 4.950%—while extending the maturity by approximately three years. The $300 million in new notes will partially refinance the $500 million in maturing debt, with the company indicating it will use existing cash for the balance.
The filing was signed by Ankur Dhingra, Chief Financial Officer, and included legal opinions from Cravath, Swaine & Moore LLP (8-K filing, 2026-08-17). The offering closed on the same day as the filing.
