Tempus AI, Inc. (NASDAQ: TEM) issued $650 million in 0.75% Convertible Senior Notes due 2030 in July 2025, with an over-allotment option for an additional $100 million, potentially bringing the total issuance to $750 million. This issuance will significantly impact TEM's debt structure and future interest expenses.1
Impact on Debt Structure:
The issuance adds a substantial amount of new debt to Tempus AI's balance sheet. These notes are classified as "general unsecured obligations," meaning they rank below any secured debt the company might have but are senior to equity in the event of liquidation.1 The convertible nature of these notes introduces a hybrid security that possesses characteristics of both debt and equity. While initially recorded as debt, the potential for conversion into Class A ordinary shares means that a portion or all of this debt could eventually be reclassified as equity, leading to dilution for existing shareholders if the stock price exceeds the conversion price.
Impact on Future Interest Expenses:
The 0.75% annual interest rate on these convertible senior notes will result in a new, recurring interest expense for Tempus AI.1
- If the initial $650 million was issued, the annual interest expense would be $4,875,000 ($650,000,000 * 0.0075).1
- If the full $750 million, including the over-allotment option, was issued, the annual interest expense would be $5,625,000 ($750,000,000 * 0.0075).1
This interest is payable semi-annually, with payments beginning on January 15, 2026, and continuing on July 15 and January 15 of each subsequent year until maturity in 2030.1 This new expense will need to be factored into the company's financial projections and cash flow management.
