6. INVESTMENT SECURITIES

Available-For-Sale Securities

The amortized cost and estimated fair value of securities available-for-sale by contractual maturity at March 31, 2026 is shown in the following table. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Maturities for mortgage-backed securities and collateralized mortgage obligations are dependent upon the interest rate environment and prepayments of the underlying loans.

Proceeds from sales of investment securities available-for-sale were approximately $0 and $0 for the three months ended March 31, 2026 and 2025, respectively.

At March 31, 2026 and December 31, 2025, investment securities available-for-sale totaling approximately $226,967,000 and $234,159,000, respectively, were pledged as collateral for repurchase agreements and deposits of public funds.

The following table presents information related to the Company’s gains and losses on the sales and calls of securities available-for-sale, and losses recognized for the impairment of these investments. Gains and losses on available-for-sale securities are computed on the specific identification method and included in non-interest income. Gross realized losses on debt securities are net of impairment charges:

The tax applicable to the net realized losses for the three-month periods ended March 31, 2026 and 2025 was $0 and $0, respectively. The tax applicable to the net realized losses for the nine-month periods ended March 31, 2026 and 2025 was $0 and $0, respectively.

QNB follows the accounting guidance in FASB ASC 326-10 as it relates to the recognition and presentation of impairment. This accounting guidance specifies that (a) if a company does not have the intent to sell a debt security prior to recovery and (b) it is more likely than not that it will not have to sell the debt security prior to recovery, the security would not be considered impaired unless there is a credit loss. When an entity does not intend to sell the security, and it is more likely than not that the entity will not have to sell the security before recovery of its cost basis, it will recognize the credit component of an impairment of a debt security in earnings and the remaining portion in other comprehensive loss. No credit impairments were recognized on debt securities during the three months ended March 31, 2026 and 2025, respectively.

Management evaluates debt securities, which are comprised of U.S. Treasury, U.S. Government agencies, state and municipalities, mortgage-backed securities, CMOs and corporate debt securities, for impairment and considers the current economic conditions, interest rates and the bond rating of each security. The unrealized losses at March 31, 2026 in U.S. Government agency securities, state and municipal securities, mortgage-backed securities, CMOs and corporate debt securities are primarily the result of interest rate fluctuations. If held to maturity, these bonds will mature at par, and QNB will not realize a loss. QNB has the intent to hold the securities and does not believe it will be required to sell the securities before recovery occurs.
