In March 2018, the Company issued $330.0 million in aggregate principal amount, of 5.00% Fixed-to-Floating Rate Subordinated Notes (“2018 Notes”) at a public offering price equal to 100% of the aggregate principal amount of the 2018 Notes. The Company incurred $3.6 million in debt issuance costs related to the offering during March 2018. The 2018 Notes were to mature on April 1, 2028 and initially bore interest at a fixed rate of 5.00% per annum, payable semi-annually in arrears. From and including April 1, 2023 to, but excluding, the maturity date or the date of earlier redemption, the interest rate would reset quarterly to an annual interest rate equal to the “then-current three month LIBOR rate” plus 215 basis points, payable quarterly in arrears. The Company transitioned from the “then-current three month LIBOR rate” to the “three-month Secured Overnight Financing Rate” (“SOFR”), plus a comparable spread adjustment of 26.161 basis points,” beginning with interest accrued on the 2018 Notes from and after October 1, 2023. The Company used a portion of the net proceeds from the sale of the 2018 Notes to repay certain outstanding indebtedness. The 2018 Notes qualified for Tier 2 capital treatment. During the third quarter of 2025, the Company issued a notice of redemption to redeem the 2018 Notes, which were redeemed in full on October 1, 2025. The related remaining $565,000 of unamortized debt issuance costs were written off during the quarter ended September 30, 2025. See Note 23, Subsequent Event, for additional information. The Company assumed subordinated debt in an aggregate principal amount, net of premium adjustments, of $37.4 million in connection with the Spirit acquisition in April 2022 (“Spirit Notes”). The Spirit Notes were to mature on July 31, 2030, and initially bore interest at a fixed annual rate of 6.00%, payable quarterly, in arrears, to, but excluding, July 31, 2025. From and including July 31, 2025, to, but excluding, the maturity date or earlier redemption date, the interest rate would reset quarterly to an interest rate per annum equal to a benchmark rate, which was the then-current three-month SOFR rate, as published by the Federal Reserve Bank of New York, payable quarterly, in arrears. During the third quarter of 2025, the Company issued a notice of redemption to redeem the Spirit Notes, which were redeemed in full on July 31, 2025. In September 2025, the Company issued $325.0 million in aggregate principal amount, of 6.25% Fixed-to-Floating Rate Subordinated Notes (“2025 Notes”) at a public offering price equal to 100% of the aggregate principal amount of the 2025 Notes. The Company incurred $3.9 million in debt issuance costs related to the offering during September 2025. The 2025 Notes will mature on October 1, 2035 and will bear interest at an initial fixed rate of 6.25% per annum, payable semi-annually, in arrears. From and including October 1, 2030 to, but excluding, the maturity date or the date of earlier redemption, the interest rate resets quarterly to an annual interest rate equal to the then-current three month SOFR rate plus 302 basis points, payable quarterly, in arrears. Additionally, during the third quarter of 2025, the Company began utilizing interest rate swaps designated as fair value hedges to mitigate the risk of changes in the fair value of the aggregate principal amount of the 2025 Notes due to changes in market interest rates. See Note 22, Derivative Instruments, for further discussion regarding fair value hedges. The 2025 Notes will be subordinated in right of payment to the payment of the Company’s other existing and future senior indebtedness, including all of its general creditors. The 2025 Notes are obligations of the Company only and are not obligations of, and are not guaranteed by, any of its subsidiaries. The Company used the net proceeds from the sale of the 2025 Notes, together with cash on hand, to fully redeem the 2018 Notes on October 1, 2025, and for general corporate purposes. The 2025 Notes qualify for Tier 2 capital treatment. The Company had total outstanding FHLB advances of $2.7 million and $727.9 million at September 30, 2025 and December 31, 2024, respectively. The outstanding FHLB advances as of December 31, 2024 were primarily whole loan advances, which are due less than one year from origination and therefore were classified as short-term advances by the Company. The decrease in FHLB advances during the nine months ended September 30, 2025 was due to the pay down of higher cost wholesale funding, including the FHLB advances, using the proceeds from the sale of securities during the third quarter of 2025. At September 30, 2025, the FHLB advances outstanding were secured by mortgage loans and investment securities totaling approximately $6.64 billion and the Company had approximately $6.13 billion of additional advances available from the FHLB. The Company’s long-term debt primarily includes subordinated debt and other notes payable. The aggregate contractual annual maturities of long-term debt at September 30, 2025, are as follows:
Year |  | (In thousands)
Remainder of 2025 |  | $ | 394 |
2026 |  | 1,703 |
2027 |  | 1,764 |
