For both the three and six months ended June 30, 2026 there were no weighted average anti-dilutive stock options excluded from diluted earnings per share. For both the three and six months ended June 30, 2025 there were approximately 8 thousand weighted average anti-dilutive stock options excluded from diluted earnings per share. The stock options were anti-dilutive because the strike price is greater than the average fair value of the Company’s common stock.

Index

At June 30, 2026 and December 31, 2025, the Company had approximately $45.7 million and $41.9 million of real estate construction loans, respectively. Of the $45.7 million in real estate construction loans at June 30, 2026, approximately $14.5 million are secured by first mortgages to residential borrowers while approximately $31.2 million are to commercial borrowers for residential construction projects. Of the $41.9 million in real estate construction loans at December 31, 2025, approximately $11.9 million were secured by first mortgages to residential borrowers while approximately $30.0 million were to commercial borrowers for residential construction projects. The vast majority of construction loans were in the Company’s New York market.

Allowance for credit losses on loans

The allowance for credit losses on loans (“ACLL”) reflects management's estimate of expected credit losses over the life of the loan portfolio. The ACLL level is influenced by past events and current conditions, as well as reasonable and supportable forecasts of future economic scenarios. The ACLL level is updated quarterly based on the latest available information and assumptions. During the quarter ended June 30, 2026, the Company enhanced the ACLL calculation as follows:

• The Company updated its prepayment and curtailment assumptions based on recent experience within its portfolio.

The following assumptions and other inputs continue to be applied in the Company’s methodology:

• Use a Discounted Cash Flow Methodology using the probability of default and loss given default approach, and continues to utilize peer data.
• Use a reasonable and supportable forecast period, which is based on a Moody's Baseline Scenario for four quarters.
• Use of reversion period, which is the period after the forecast period when the ACLL factors revert to historical averages, using a four-quarter straight line reversion.
• Use of qualitative considerations, which are adjustments to the ACLL quantitative reserves to account for changes in various internal and external factors that affect the credit quality of the loan portfolio. The qualitative considerations are allocated utilizing a weighted scorecard framework. The qualitative factors utilized continued to be based on regulatory (interagency) guidelines.

The enhancement did not have a material impact on the Company’s financial statements.

The Company recorded a provision for credit losses of $650 thousand for the three months ended June 30, 2026, which is the result of a provision for credit losses on loans of $1.0 million and a $350 thousand benefit for credit losses on unfunded commitments during the three months ended June 30, 2026. The Company recorded a provision for credit losses of $1.6 million for the six months ended June 30, 2026, which is the result of a provision for credit losses on loans of $1.75 million and a $150 thousand benefit for credit losses on unfunded commitments during the six months ended June 30, 2026.

The Company’s activity in the allowance for credit losses on unfunded commitments for the three and six months ended June 30, 2026 and 2025 were as follows:

Loan Credit Quality

The Company categorizes commercial loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. On at least an annual basis, the Company’s loan grading process analyzes non-homogeneous loans, such as commercial loans and commercial real estate loans, individually by grading the loans based on credit risk. The loan grades assigned to all loan types are tested by the Company’s internal loan review department in accordance with the Company’s internal loan review policy.

The Company uses the following definitions for classified loans:

Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date.

25

Index

Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as such have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those loans classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loans not meeting the criteria above are considered to be “pass” rated loans.

For homogeneous loan pools, such as residential mortgages, home equity lines of credit, and installment loans, the Company uses payment status to identify the credit risk in these loan portfolios. Payment status is reviewed on a daily basis by the Bank’s collection area and on a monthly basis with respect to determining the adequacy of the allowance for credit losses on loans. The payment status of these homogeneous pools as of June 30, 2026 and December 31, 2025 is also included in the aging of the past due loans table. Nonperforming loans shown in the table below were loans on nonaccrual status and loans over 90 days past due and accruing.

A financial asset is considered collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. Expected credit losses for the collateral dependent loans are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. The following tables present the amortized cost basis of individually analyzed collateral dependent loans by portfolio segment as of June 30, 2026 and December 31, 2025:

The Company has not committed to lend additional amounts to customers with outstanding loans that are on non-accrual or loan modifications to borrowers experiencing financial difficulty. Interest income recognized on loans that are individually evaluated was not material during the three and six months ended June 30, 2026 and 2025.

33

Index

As of June 30, 2026 and December 31, 2025 loans individually evaluated included approximately $6.4 million and $7.0 million, respectively, of loans in accruing status that were identified as loan modifications in accordance with regulatory guidance related to Chapter 7 and 13 bankruptcy loans.

Pursuant to the adoption of ASU 2022-02 - Financial Instruments - Credit Losses (Topic 326) Troubled Debt Restructuring and Vintage Disclosures (“ASU 2022-02”), a borrower that is experiencing financial difficulty and receives a modification in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay or a term extension in the current period needs to be disclosed.

Index

The addition of these loan modifications did not have a significant impact on the allowance for credit losses on loans. The nature of the modifications that resulted in them being classified as a loan modification was the borrower modifying their payment terms. There was 1 loan modification totaling $235 thousand for a residential mortgage modification that defaulted during the three and six months ended June 30, 2026 which had been classified as a loan modification within the prior twelve months. There was 1 loan modification totaling $80 thousand for residential mortgages and 1 home equity line of credit loan modification totaling $126 thousand that defaulted during the three months ended June 30, 2025 which had been classified as a loan modification within the prior twelve months. There was 1 loan modification totaling $80 thousand for residential mortgages and 2 home equity line of credit loan modifications totaling $247 thousand that defaulted during the six months ended June 30, 2025 which had been classified as a loan modification within the prior twelve months. These loans that defaulted were all payment delay modifications.

In situations where the Bank considers a loan modification, management determines whether the borrower is experiencing financial difficulty by performing an evaluation of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s underwriting policy.

Generally, the modification of the terms of loans is the result of the borrower filing for bankruptcy protection. Chapter 13 bankruptcies generally include the deferral of all past due amounts for a period of generally 60 months in accordance with the bankruptcy court order. In the case of Chapter 7 bankruptcies even though there is no modification of terms, the borrowers’ debt to the Company is discharged and they do not reaffirm the debt.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. In situations involving a borrower filing for Chapter 13 bankruptcy protection, however, a loan is considered to be in payment default once it is 30 days contractually past due, consistent with the treatment by the bankruptcy court.

(6) Fair Value of Financial Instruments

FASB Topic 820, Fair Value Measurements (“ASC 820”) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair values:

Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date.

Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the value that market participants would use in pricing an asset or liability.

41

Index

The Company used the following methods and significant assumptions to estimate the fair value of assets and liabilities:

Securities Available for Sale: The fair value of securities available for sale is determined utilizing an independent pricing service for identical assets or significantly similar securities. The pricing service uses a variety of techniques to arrive at fair value including market maker bids, quotes and pricing models. Inputs to the pricing models include recent trades, benchmark interest rates, spreads and actual and projected cash flows. This results in a Level 2 classification of the inputs for determining fair value. Interest and dividend income is recorded on the accrual method and is included in the Consolidated Statements of Income in the respective investment class under total interest and dividend income. The Company does not have any securities that would be designated as Level 3.

Other Real Estate Owned: Assets acquired through loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process to adjust for differences between the comparable sales and income data available. This results in a Level 3 classification of the inputs for determining fair value.

Individually Evaluated Loans: Periodically the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain adjustments for collateral-dependent loans to adjust balances to fair value and generally have had a charge-off through the allowance for credit losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. When obtained, non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Loans individually evaluated are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

Indications of value for both collateral-dependent loans and other real estate owned are obtained from third party providers or the Company’s internal Appraisal Department. All indications of value are reviewed for reasonableness by a member of the Appraisal Department for the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value via comparison with independent data sources such as recent market data or industry-wide statistics.

There were no transfers between Level 1 and Level 2 during the three and six months ended June 30, 2026 and 2025.

(8) Revenue from Contracts with Customers

All of the Company’s revenue from contracts with customers in the scope of ASC Topic 606: Revenue from Contracts with Customers (“ASC 606”) is recognized within non-interest income. The following table presents the Company’s sources of non-interest income for the three months and six months ended June 30, 2026 and 2025. Items outside the scope of ASC 606 are noted as such.

(a) Not within the scope of ASC 606.

A description of how the Company’s revenue streams are accounted for in accordance with ASC 606 is set forth below:

Service charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction‑based, account maintenance and overdraft services. Transaction‑based fees, which include services such as stop payment charges, and wire fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance.

47

Index

Interchange Income: Interchange revenue primarily consists of interchange fees, volume‑related incentives and ATM charges. As the card‑issuing bank, interchange fees represent our portion of discount fees paid by merchants for credit/debit card transactions processed through the interchange network. The levels and structure of interchange rates are set by the card processing companies and are based on cardholder purchase volumes. The Company earns interchange income as cardholder transactions occur and interchange fees are settled on a daily basis concurrent with the transaction processing services provided to the cardholder.

Wealth Management fees: Trustco Wealth Management provides a comprehensive suite of trust and wealth management products and services, including financial and estate planning, trustee and custodial services, investment management, corporate retirement plan recordkeeping and administration of which a fee is charged to manage assets for investment or transact on accounts. These fees are earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed over the period in which services are performed based on a percentage of the fair value of assets under management or administration. Other services are based on a fixed fee for certain account types, or based on transaction activity and are recognized when services are rendered. Fees are withdrawn from the customer’s account balance.

Gains/Losses on Sales of Other Real Estate Owned “OREO”: The Company records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain/(loss) on sale if a significant financing component is present.

(9) Operating Leases

The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Company’s balance sheets.

Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine present value of operating lease liabilities. Additionally, the Company does allocate the consideration between lease and non-lease components. The Company’s lease terms may include options to extend when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. As of June 30, 2026 the Company did not have any leases with terms of twelve months or less.

(10) Regulatory Capital Requirements

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy regulations and, additionally for banks, the prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory action. As of June 30, 2026, the Company and Bank meet all capital adequacy requirements to which they are subject.

Prompt corrective action regulations provide five classifications: well, capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If a bank is not classified as well capitalized, regulatory approval is required to accept brokered deposits. If a bank is undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. The federal banking agencies are required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution or its holding company. Such actions could have a direct material effect on an institution’s or its holding company’s financial statements. As of June 30, 2026 and December 31, 2025, the most recent regulatory guidance categorized the Bank as well capitalized under the regulatory framework for prompt corrective action.

(11) Segment Reporting

The Company's reportable segment is determined by the Chief Executive Officer, who is designated the chief operating decision maker (CODM), based upon information provided about the Company's products and services offered, primarily banking operations. Consolidated net income of the Company is the primary performance metric utilized by the CODM. The chief operating decision maker will evaluate the financial performance of the Company's business components such as by evaluating revenue streams, significant expenses, and budget to actual results in assessing the Company's segment and in the determination of allocating resources. All expenses associated with the Company's banking operations are considered to be significant. Given the Company's single reportable operating segment, assets associated with the Company's banking operations are reflected on the Company's consolidated statements of condition as “total assets” and the amounts of significant segment expenses are disclosed in the Company's consolidated statements of income. The accounting policies for the Company's banking operations are the same as the Company's accounting policies disclosed herein.

While the Company has assigned certain management responsibilities by region and business line, the Company’s chief decision-maker monitors and evaluates financial performance on a Company-wide basis. The majority of the Company’s revenue is from the business of banking and the Company’s assigned regions have similar economic characteristics, products, services and customers. Accordingly, all of the Company’s operations are considered by management to be aggregated in one reportable operating segment. All operations are domestic.

(12) New Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" (ASU 2024-03). ASU 2024-03 requires additional interim and annual disclosures that further disaggregate certain expense captions into specified categories in a separate note to the financial statements, as well as certain qualitative information describing amounts not separately disaggregated. ASU 2024-03 is effective for the Company in the annual period beginning on January 1, 2027 and interim periods beginning on January 1, 2028 and can be applied on either a prospective or retrospective basis, with early adoption permitted. The Company is evaluating the impact of ASU 2024-03 on its disclosures.

In December 2025, the FASB issued ASU 2025-11, "Interim Reporting (Topic 270): Narrow Scope Improvements", to improve the guidance in Topic 270, by clarifying interim disclosure requirements and the applicability of Topic 270. The amendments in this update result in a comprehensive list of interim disclosures that are required by GAAP. In developing the list of disclosures required by other Topics, the FASB board focused on identifying the interim disclosures that are currently required under GAAP. The amendments in this update also include a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in this update also clarify the applicability of Topic 270, the types of interim reporting, and the form and content of interim financial statements in accordance with GAAP. The FASB board expects these clarifications will enhance consistency in interim financial reporting in interim for all entities and considers the amendments to be necessary to reflect the development of interim reporting over time. The amendments in this update are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, for public business entities and for interim reporting periods within annual reporting periods beginning after December 15, 2027, for entities other than public business entities. Early adoption is permitted for all entities, and can be applied either (1) prospectively or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of this update on its financial disclosures, but does not expect the adoption of this update to have a material impact on the consolidated financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Glenville, New York

Results of Review of Interim Financial Information

We have reviewed the consolidated statement of financial condition of TrustCo Bank Corp NY (the "Company") as of June 30, 2026, and the related consolidated statements of income and comprehensive income for the three and six-month periods ended June 30, 2026 and June 30, 2025 and the related changes in shareholders’ equity and cash flows for the six-month periods ended June 30, 2026 and June 30, 2025, and the related notes (collectively referred to as the "interim financial information or statements"). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated financial statements referred to above for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated statement of financial condition of the Company as of December 31, 2025, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated March 16, 2026, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated statement of financial condition as of December 31, 2025, is fairly stated, in all material respects, in relation to the consolidated statement of condition from which it has been derived.

Basis for Review Results

These financial statements are the responsibility of the Company's management. We conducted our review in accordance with the standards of the PCAOB. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.
