Subordinated Indebtedness
The Company had subordinated promissory notes that were assumed in the merger with BTH (“BTH Notes”) with origination dates ranging from June 2015 to June 2021. After the five-year anniversary of issuance, the Company had the right to redeem the BTH Notes, in part or in full, at the Company’s discretion and, if applicable, subject to receipt of any required regulatory approvals. Primarily due to the declining Tier 2 capital treatment of the BTH Notes, the Company elected to redeem majority of the BTH Notes during the year ended December 31, 2024, and redeemed the remaining balance of $1.1 million during the year ended December 31, 2025.
In February 2020, Origin Bank completed an offering of $70.0 million in aggregate principal amount of 4.25% fixed-to-floating rate subordinated notes due 2030 (the “4.25% Notes”) to certain investors in a transaction exempt from registration under Section 3(a)(2) of the Securities Act of 1933, as amended. The 4.25% Notes bore interest at a fixed annual rate of 4.25%, payable semi-annually in arrears, to but excluding February 15, 2025. From and including February 15, 2025, to but excluding the maturity date or early redemption date, the interest rate would equal the three-month LIBOR rate plus 282 basis points, payable quarterly in arrears. On June 30, 2023, in conjunction with the customary fallback provision upon the discontinuation of LIBOR, the rate for the floating rate periods from and including February 15, 2025, on these notes transitioned to the three-month term SOFR plus 308 basis points. Origin Bank elected to redeem the 4.25% Notes on February 15, 2025, as permitted under the terms of the 4.25% Notes.
In October 2020, the Company completed of an offering of $80.0 million in aggregate principal amount of 4.50% fixed-to-floating rate subordinated notes due 2030 (the “4.50% Notes”). The 4.50% Notes bear a fixed interest rate of 4.50% payable semi-annually in arrears, to but excluding November 1, 2025. From and including November 1, 2025, to but excluding the maturity date or earlier redemption date, the interest rate would equal the three-month term Secured Overnight Financing Rate plus 432 basis points, payable quarterly in arrears. During the years ended December 31, 2025, 2024 and 2023, and with the approval of the Board of Governors of the Federal Reserve System, the Company redeemed or repurchased $74.0 million, $1.0 million and $5.0 million, respectively, of the 4.50% Notes leaving no 4.50% Notes outstanding as of December 31, 2025.
