QUAINT OAK BANCORP, INC. ANNOUNCES SECOND QUARTER EARNINGS

Southampton, PA – Quaint Oak Bancorp, Inc. (the “Company”) (OTCQB: QNTO), the holding company for Quaint Oak Bank (the “Bank”), announced today net income for the quarter ended June 30, 2026 of $481,000, or $0.18 per basic and diluted share, compared to net income of $272,000, or $0.10 per basic and diluted share, for the same period in 2025. Net income for the six months ended June 30, 2026 was $647,000, or $0.24 per basic and diluted share, compared to net income of $189,000, or $0.07 per basic and diluted share, for the same period in 2025.

Robert T. Strong, Chief Executive Officer, stated, “I am pleased to report that our second quarter and year-to-date operating results improved significantly compared to the same periods in 2025. Net income increased 76.8% for the quarter and more than tripled on a year-to-date basis. These results reflect continued progress in balance sheet management, improved funding costs, net interest margin expansion, and growth in non-interest income generated from our diversified business lines.”

Mr. Strong continued, “One of the more encouraging aspects of the quarter was the continued improvement in the quality of our earnings. While our average interest rate spread decreased to 2.14% for the quarter from 2.19% a year ago, our net interest margin improved to 2.93% from 2.85%. These improvements were driven primarily by a meaningful reduction in our cost of funds and the ongoing benefits of disciplined asset and liability management.”

Mr. Strong added, “We continue to see the benefits of investments made over the past several years in our specialty banking platforms, technology infrastructure, and personnel. Non-interest income improved meaningfully during the quarter, reflecting the contribution of our diversified business model and our ongoing efforts to develop scalable sources of revenue beyond traditional spread income. At the same time, we remain focused on operating efficiency, as demonstrated by continued improvement in our efficiency ratio compared to the prior year.”

Mr. Strong noted, “While overall credit quality remains manageable, we experienced an increase in non-performing assets during the first six months of the year. Importantly, these assets are either well-collateralized or appropriately reserved for, and we continue to actively pursue resolution strategies. During the period, we charged off certain previously identified commercial business loans through the allowance for credit losses, reflecting our disciplined approach to credit administration and balance sheet management.”

Mr. Strong concluded, “Our capital position remains strong, stockholders' equity increased modestly during the first six months of the year, and we continue to operate without Federal Home Loan Bank borrowings. As we move forward through our Centennial Year, our focus remains unchanged: disciplined execution, long-term profitability, prudent risk management, and maintaining healthy capital levels, all of which reflect our ongoing commitment to enhancing shareholder value.”

Comparison of Quarter-Over-Quarter Operating Results

Net income amounted to $481,000 for the three months ended June 30, 2026, an increase of $209,000, or 76.8%, compared to net income of $272,000 for the three months ended June 30, 2025. The increase in net income over the comparable quarterly period was primarily the result of a decrease in interest expense of $760,000 and an increase in non-interest income of $361,000, partially offset by a decrease in interest and dividend income of $694,000, an increase in non-interest expense of $112,000, a net increase in the provision for credit losses of $63,000, and an increase in the provision for income taxes of $43,000.

The $694,000, or 6.8%, decrease in interest and dividend income for the three months ended June 30, 2026 was primarily due to a $17.3 million decrease in the average balance of loans receivable, which decreased from $589.4 million for the three months ended June 30, 2025 to $572.1 million for the three months ended June 30, 2026 and had the effect of decreasing interest income by $284,000, and a 207 basis point decrease in the average yield on due from banks – interest earning, which decreased from 4.21% for the three months ended June 30, 2025 to 2.18% for the three months ended June 30, 2026 and had the effect of decreasing interest income $258,000. Also contributing to the decrease in interest income was a 15 basis point decrease in the average yield on loans receivable, which decreased from 6.58% for the three months ended June 30, 2025 to 6.43% for the three months ended June 30, 2026 and had the effect of decreasing interest income $210,000. Partially offsetting the decrease in interest and dividend income was a $14.0 million increase in the average balance of due from banks – interest earning, which increased from $37.7 million for the three months ended June 30, 2025 to $51.7 million for the three months ended June 30, 2026, and had the effect of increasing interest income $147,000.

The $760,000, or 13.4%, decrease in interest expense for the three months ended June 30, 2026 over the comparable period in 2025 was driven by a $648,000, or 100.0%, decrease in interest on Federal Home Loan Bank (“FHLB”) borrowings, which was attributable to a decrease in the average balance of FHLB borrowings which decreased from $56.3 million for the three months ended June 30, 2025, to none for the three months ended June 30, 2026, a $70.6 million decrease in the average balance of money market deposits which decreased from $142.9 million for the three months ended June 30, 2025 to $72.3 million for the three months ended June 30, 2026 and had the effect of decreasing interest expense by $627,000, a 27 basis point decrease in the average rate of certificates of deposit from 4.27% for the three months ended June 30, 2025 to 4.00% for the three months ended June 30, 2026, which had the effect of decreasing interest expense by $227,000, and a 114 basis point decrease in the average rate of money markets from 3.58% for the three months ended June 30, 2025 to 2.44% for the three months ended June 30, 2026, which had the effect of decreasing interest expense by $182,000. These decreases in interest expense were partially offset by an $80.9 million increase in the average balance of business checking accounts, which increased from $10.7 million for the three months ended June 30, 2025, to $91.6 million for the three months ended June 30, 2026 and had the effect of increasing interest expense by $496,000, a $36.4 million increase in the average balance of certificates of deposit which increased from $305.8 million for the three months ended June 30, 2025 to $342.1 million for the three months ended June 30, 2026 and had the effect of increasing interest expense by $387,000. The average interest rate spread decreased from 2.19% for the three months ended June 30, 2025 to 2.14% for the three months ended June 30, 2026 and the net interest margin increased from 2.85% for the three months ended June 30, 2025 to 2.93% for the three months ended June 30, 2026.

The $63,000, or 14.4%, net increase in the provision for credit losses for the three months ended June 30, 2026 over the comparable period in 2025 was primarily due to an increase in the balance of individually evaluated loans and their associated reserve during the period.

The $361,000, or 18.5%, increase in non-interest income for the three months ended June 30, 2026 over the comparable period in 2025 was primarily attributable to a $404,000, or 38.6%, increase in net gain on sale of mortgage and Oakmont Commercial loans, a $136,000 increase in loan servicing income, and a $21,000 increase in other fees and services charges, net. These increases were partially offset by a $97,000, or 19.0%, decrease in gain on sale of SBA loans, an $86,000, or 30.7%, decrease in mortgage banking and title abstract fees, and a $20,000, or 10.2%, decrease in insurance commissions. The increase in loan servicing income reflects the retention of servicing on certain loan sales.

The $112,000, or 2.0%, increase in non-interest expense for the three months ended June 30, 2026 over the comparable period in 2025 was primarily due to a $182,000, or 5.0%, increase in salaries and employee benefits expense, a $119,000, or 68.4%, increase in professional fees, a $40,000, or 14.3%, increase in other expense, and a $16,000, or 11.9%, increase in FDIC deposit insurance assessment. These increases in non-interest expense were partially offset by a $119,000, or 27.1%, decrease in data processing expense, a $75,000, or 115.4%, decrease in directors’ fees and expenses, a $39,000, or 9.0% decrease in occupancy and equipment expenses, a $9,000, or 9.0%, decrease in advertising expense, and a $3,000, or 1.2%, decrease in software as a service (“SaaS”) subscription expense. The increase in professional fees during the quarter was primarily due to international correspondent banking compliance related activities as the Bank is continuing to build out this line of business. The decrease in directors’ fees and expenses reflects a one-time adjustment based on a reassessment of the director fee accrual based at June 30, 2026.

The provision for income tax increased $43,000 from $210,000 for the three months ended June 30, 2025 to $253,000 for the three months ended June 30, 2026, primarily due to an increase in pre-tax income.

Comparison of Six-Month Operating Results

Net income amounted to $647,000 for the six months ended June 30, 2026, an increase of $458,000, or 242.3%, compared to net income of $189,000 for the six months ended June 30, 2025. The increase in net income on a comparative six-month basis was primarily the result of a decrease in interest expense of $1.3 million, a net decrease in the provision for credit losses of $282,000, and an increase in non-interest income of $414,000, partially offset by a decrease in interest and dividend income of $725,000, an increase in non-interest expense of $692,000, and an increase in the provision for income taxes of $161,000.

The $725,000, or 3.6%, decrease in interest and dividend income for the six months ended June 30, 2026 over the comparable period in 2025 was primarily due to an $8.6 million decrease in the average balance of loans receivable, which decreased from $589.1 million for the six months ended June 30, 2025 to $580.5 million for the six months ended June 30, 2026, and had the effect of decreasing interest income $280,000, an 83 basis point decrease in the average yield on due from banks – interest earning, which decreased from 4.03% for the six months ended June 30, 2025 to 3.20% for the six months ended June 30, 2026 and had the effect of decreasing interest income $130,000. Also contributing to the decrease in interest and dividend income for the quarter was a five basis point decrease in the average yield on loans receivable, which decreased from 6.53% for the six months ended June 30, 2025 to 6.48% for the six months ended June 30, 2026 and had the effect of decreasing interest income $121,000, and a $5.9 million decrease in the average balance of due from banks – interest earning, which decreased from $37.1 million for the six months ended June 30, 2025 to $31.2 million for the six months ended June 30, 2026, and had the effect of decreasing interest income $120,000.

The $1.3 million, or 11.7%, decrease in interest expense for the six months ended June 30, 2026 over the comparable period in 2025 was driven by a $78.4 million decrease in the average balance of money market deposits which decreased from $151.1 million for the six months ended June 30, 2025 to $72.7 million for the six months ended June 30, 2026 and had the effect of decreasing interest expense by $1.4 million, a $1.1 million, or 100.0% decrease in interest on FHLB borrowings, which was attributable to a decrease in the average balance of FHLB borrowings which decreased from $50.7 million for the six months ended June 30, 2025, to none for the six months ended June 30, 2026, a 27 basis point decrease in the average rate of certificates of deposit from 4.24% for the six months ended June 30, 2025 to 3.97% for the six months ended June 30, 2026, which had the effect of decreasing interest expense by $477,000, and a 114 basis point decrease in the average rate of money markets from 3.58% for the six months ended June 30, 2025 to 2.44% for the six months ended June 30, 2026, which had the effect of decreasing interest expense by $416,000. These decreases in interest expense were partially offset by a $54.2 million increase in the average balance of certificates of deposit which increased from $295.3 million for the six months ended June 30, 2025 to $349.6 million for the six months ended June 30, 2026 and had the effect of increasing interest expense by $1.2 million, a $60.2 million increase in the average balance of business checking accounts, which increased from $19.4 million for the six months ended June 30, 2025, to $79.6 million for the six months ended June 30, 2026 and had the effect of increasing interest expense by $1.1 million. The average interest rate spread increased from 2.13% for the six months ended June 30, 2025 to 2.43% for the six months ended June 30, 2026 and the net interest margin increased from 2.74% for the six months ended June 30, 2025 to 3.02% for the six months ended June 30, 2026.

The $282,000, or 32.1%, net decrease in the provision for credit losses for the six months ended June 30, 2026 over the six months ended June 30, 2025 was primarily due to a decrease in charge-offs and a decrease in the commercial and industrial loan balances, during the six months ended June 30, 2026.

The $414,000, or 11.2%, increase in non-interest income for the six months ended June 30, 2026 over the comparable period in 2025 was primarily attributable to a $413,000, or 50.5%, increase in gain on sale of SBA loans, a $336,000, or 16.0%, increase in net gain on sale of mortgage and Oakmont Commercial loans, and a $219,000 increase in loan servicing income. These increases were partially offset by a $396,000 decrease in other fees and services charges, net, a $141,000, or 33.1%, decrease in mortgage banking and title abstract fees, and a $23,000, or 6.0%, decrease in insurance commissions. Other fees and services charges, net declined primarily due to SBA lending-related items, including a $152,000 write-down of the SBA servicing asset due to a valuation adjustment and the write-off of $199,000 of certain deferred SBA loan origination costs associated with SBA loan sales completed during the period. Additionally, loan servicing income increased, reflecting the retention of servicing on certain loan sales.

The $692,000, or 6.2%, increase in non-interest expense for the six months ended June 30, 2026 over the comparable period in 2025 was primarily due to a $531,000, or 7.3%, increase in salaries and employee benefits expense, a $245,000, or 61.7% increase in professional fees, a $98,000, or 20.7%, increase in software as a service (“SaaS”) subscription expense, a $69,000, or 11.5% increase in other expense, and a $60,000, or 23.4%, increase in FDIC deposit insurance assessment. These increases in non-interest expense were partially offset by a $182,000, or 21.6%, decrease in data processing expense, a $72,000, or 55.4%, decrease in directors’ fees and expenses, a $40,000, or 4.6%, decrease in occupancy and equipment expenses, and a $17,000, or 8.5%, decrease in advertising expense. The increase in salaries and employee benefits expense was primarily due to a $233,000 increase in salaries, and a $240,000 increase in bonus expense due to a voluntary reduction in discretionary incentive compensation driven by lower performance results for the six months ended June 30, 2025. The increase in professional fees during the period was primarily due to international correspondent banking compliance-related activities as the Bank continues to build out this line of business. The increase in SaaS subscription expense reflects the phased implementation and expanded utilization of third-party software solutions supporting compliance, risk management, and operational infrastructure, partially offset by reductions in traditional data processing costs. The decrease in directors’ fees and expenses reflects a one-time adjustment based on a reassessment of the director fee accrual based at June 30, 2026.

The provision for income tax increased $161,000, or 75.9%, from $212,000 for the six months ended June 30, 2025 to $373,000 for the six months ended June 30, 2026 due primarily to an increase in pre-tax income.

Comparison of Financial Condition

The Company’s total assets at June 30, 2026 were $630.3 million, a decrease of $45.5 million, or 6.7%, from $675.9 million at December 31, 2025. The decrease in total assets was primarily due to a $21.3 million, or 34.9%, decrease in loans held for sale, a $19.3 million, or 3.6%, decrease in loans receivable, net of allowance for credit losses, and a $5.3 million, or 9.9%, decrease in cash and cash equivalents.

Loans held for sale decreased $21.3 million, or 34.9%, from $61.0 million at December 31, 2025 to $39.7 million at June 30, 2026 as the Bank’s commercial real estate subsidiary, Oakmont Commercial, LLC, originated $28.2 million of commercial real estate loans during the six months ended June 30, 2026 and sold $47.6 million of loans in the secondary market during this same period. The Bank’s mortgage banking subsidiary, Quaint Oak Mortgage, LLC, originated $48.9 million of one-to-four family residential loans during the six months ended June 30, 2026 and sold $49.2 million of loans in the secondary market. During the six months ended June 30, 2026, the Bank originated $16.4 million of SBA loans and sold $16.2 million of SBA loans in the secondary market during the same period.

These decreases in deposits were partially offset by an increase of $8.1 million, or 11.5%, in money market accounts. Both retail and non-retail interest-bearing checking account balances decreased at June 30, 2026, compared to December 31, 2025, primarily reflecting increased competition for such deposits.

Total stockholders’ equity increased $644,000, or 1.2%, to $53.0 million at June 30, 2026 from $52.3 million at December 31, 2025.

The increase in stockholders’ equity was partially offset by dividends paid of $211,000, purchase of treasury stock of $31,000, and other comprehensive loss, net of $1,000.
