This Form 6-K filing by STMicroelectronics N.V. (ST) covers the period of June 16, 2026. The filing discloses a significant capital market transaction involving the issuance of new debt securities and the early redemption of existing convertible bonds. ST is an integrated device manufacturer specializing in semiconductor technologies.
Key Financial Metrics and Transaction Details
- New Debt Issuance: ST is launching a US$1.5 billion dual-tranche offering of senior unsecured convertible bonds (New Convertible Bonds).
- Tranche Structure:
- 2031 Convertible Bonds: Maturity of 5 years; interest rate between 0.00% and 0.50% annually.
- 2033 Convertible Bonds: Maturity of 7 years; interest rate between 0.625% and 1.125% annually.
- Redemption of Existing Debt: ST is redeeming its outstanding US$750 million Zero Coupon Convertible Bonds due 2027 (2027 Convertible Bonds) early on July 16, 2026, at their principal amount.
- Use of Proceeds: Net proceeds from the new offering will fund general corporate purposes, including the early redemption of the 2027 Convertible Bonds.
- Conversion Terms:
- 2031 Bonds: Conversion price premium of 47.5% – 52.5% over the volume-weighted average share price.
- 2033 Bonds: Conversion price premium of 50% – 55% over the volume-weighted average share price.

- Existing Bond Conversion: Holders of the 2027 Convertible Bonds may convert at a price of US$45.10 per share if the conversion date occurs on or before July 1, 2026.
Material Changes and Strategic Actions
The primary material change is the restructuring of ST's convertible debt profile. The company is replacing a US$750 million zero-coupon obligation due in 2027 with a larger US$1.5 billion tranche of coupon-bearing debt maturing in 2031 and 2033. This action extends the maturity profile of the company's debt and introduces a cash interest obligation where none previously existed for the redeemed tranche.
