​

​

Short-term debt includes FHLB advances with a remaining maturity of less than one year. We also maintain a $1.0 million secured line of credit with the FHLB that bears a daily adjustable rate calculated by the FHLB. There was no outstanding

balance on the FHLB line of credit for the years ended December 31, 2025 and 2024. There are no variable rate short-term FHLB borrowings.

We have the capacity to borrow funds on a secured basis utilizing the Borrower in Custody program, and the Discount Window at the Federal Reserve Bank of Boston (the “Reserve Bank”). As of December 31, 2025 and 2024 our available secured line of credit at the Reserve Bank was $94.0 million and $105.6 million, respectively. We have pledged certain loans and securities to the Reserve Bank to support this arrangement.

We maintain an unused unsecured federal funds line of credit with a correspondent bank that has an aggregate overnight borrowing capacity of $40 million as of December 31, 2025 and December 31, 2024. There was no outstanding balance on the line of credit as of December 31, 2025 and December 31, 2024.

Long-term FHLB advances consist of advances with a remaining maturity of more than one year. The advances outstanding at December 31, 2025 include callable advances of $80.0 million, non-callable advances of $1.0 million and amortizing advances of $1.0 million. There were no callable advances outstanding and $269 thousand of amortizing advances at December 31, 2024. All FHLB borrowings, including the line of credit, are secured by a blanket security agreement on certain qualified collateral, principally residential first mortgage loans and certain securities. There are no variable rate long-term FHLB borrowings.

A summary of maturities of FHLB advances as of December 31, 2025 is, as follows:

​

​

Each advance is payable at its maturity date, with a prepayment penalty for fixed rate advances. The advances were collateralized by $740.7 million and $781.2 million of loans under a blanket lien arrangement at year-end 2025 and 2024. Based on this collateral and the Company’s holdings of FHLB stock, the Company is eligible to borrow up to a total of $259.1 million at year-end 2025.

At year-end 2025 and 2024, subordinated borrowings was as follows:

​

​

We executed a Subordinated Note Purchase Agreement with an aggregate of $40.0 million of subordinated notes (the “Notes”) to accredited investors on November 26, 2019. The Notes have a maturity date of December 1, 2029 and bear a fixed interest rate of 4.63% through December 1, 2024 payable semi-annually in arrears. From December 1, 2024 and thereafter the interest rate shall be reset quarterly to an interest rate per annum equal to the then current three-month Secured Overnight Financing Rate (“SOFR”) plus 3.27%. We have the option beginning with the interest payment date of December 1, 2024, and on any scheduled payment date thereafter, to redeem the Notes, in whole or in part upon prior

approval of the Federal Reserve. During the fourth quarter of 2024 we paid down $20.0 million of the outstanding subordinated notes. As of December 31, 2025 we have an outstanding subordinated note balance of $20.0 million.

We also have $20.6 million in floating Junior Subordinated Deferrable Interest Debentures (“Debentures”) issued by NHTB Capital Trust II (“Trust II”) and NHTB Capital Trust III (“Trust III”), which are both Connecticut statutory trusts. The Debentures issued on March 30, 2004, carry a variable interest rate of three-month SOFR plus 2.79%, and mature in 2034. The debt is callable by the Company at the time when any interest payment is made. Trust II and Trust III are considered variable interest entities for which we are not the primary beneficiary. Accordingly, Trust II and Trust III are not consolidated into our financial statements.

In connection with the acquisition, the Company assumed $13.0 million in fixed-to-floating rate subordinated notes, (the “2031 notes”) issued by Guaranty Bancorp. The 2031 notes have a current book value of $12.2 million net of accretion. The 2031 notes were originally issued on March 23, 2021 with a maturity date of April 1, 2031. The 2031 notes bear a fixed-to-floating interest rate of 4.875% through April 1, 2026, payable quarterly in arrears. Beginning April 1, 2026 and thereafter, the interest rate shall be reset quarterly to an interest rate per annum equal to the then current three-month SOFR plus 4.82%. We have the option beginning with the interest payment date of April 1, 2026, and on any scheduled payment date thereafter, to redeem the 2031 notes, in whole or in part upon prior approval of the Federal Reserve.
