NAPCO SECURITY TECHNOLOGIES, INC

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

September 30, 2025

NOTE 1 – Description of Business, Basis of Presentation and Summary of Significant Accounting Policies

Nature of Business:

Napco Security Technologies, Inc (“Napco”, “the Company”, “we”, “our”) is one of the leading manufacturers and designers of high-tech electronic security devices, cellular communication services for intrusion and fire alarm systems as well as a leading provider of school safety solutions. We offer a diversified array of security products, encompassing access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products. These products are used for commercial, residential, institutional, industrial and governmental applications, and are sold principally to independent distributors, dealers and installers of security equipment. We have established a national network of trusted independent security dealers and integrators that are experts at selling, installing and supporting our various technologies. These dealers and installers are dependent on our platform for communication services to our radio communicators and smart security devices, and they pay us a monthly fee for these services to operate and manage their businesses efficiently.

Basis of Presentation:

The consolidated financial statements include the accounts of Napco Security Technologies, Inc. and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.

The accompanying unaudited Condensed Consolidated Financial Statements of Napco Security Technologies, Inc. have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) as defined in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification 270 for interim financial information and with the instructions to Rule 10-01 of Securities and Exchange Commission Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in the Annual Report on Form 10-K for the year ended June 30, 2025. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. All such adjustments are of a normal, recurring nature.

Significant Accounting Policies:

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent gains and losses at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We continuously evaluate our estimates and judgments based on historical experience, as well as other factors that we believe to be reasonable under the circumstances. The results of our evaluation form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Critical estimates include management’s judgments associated with reserves for sales returns and allowances, allowance for credit losses, overhead expenses applied to inventory, inventory reserves, valuation of intangible assets, share based compensation and income taxes. These estimates may change in the future if underlying assumptions or factors change, and actual results may differ from these estimates.

Fair Value of Financial Instruments

The carrying amount of cash and cash equivalents, marketable securities, current receivables and payables and certain other short-term financial instruments approximate their fair value as of December 31, 2025 and June 30, 2025 due to their short-term maturities. The fair value of debt for footnote disclosure purposes, including current maturities, if any, is estimated using recently quoted market prices of the instrument, or if not available, a discounted cash flow analysis based on the estimated current incremental borrowing rates for similar types of instruments.

Cash and Cash Equivalents

All financial instruments purchased with an original maturity of three months or less at the time of purchase are considered cash equivalents. Such items may include liquid money market funds, certificate of deposit, U.S. treasury securities and time deposit accounts. Investments that are classified as cash equivalents are carried at cost, which approximates fair value.

Cash and cash equivalents include approximately $75,814,000 and $48,249,000 of short-term time deposits money market funds as of December 31, 2025, and June 30, 2025. The Company classifies these highly liquid investments with original maturities of three months or less as cash equivalents.

Cash and cash equivalents consist of the following as of (in thousands):

The Company has cash balances in banks in excess of the maximum amount insured by the FDIC and other international agencies as of December 31, 2025. The Company has not historically experienced any credit losses with balances in excess of FDIC limits.

Marketable Securities

Investments in debt securities are classified as available-for-sale and realized gains and losses are recorded using the specific identification method. Changes in fair value, excluding credit losses and impairments, are recorded in other comprehensive income. Fair value is calculated based on publicly available market information or other estimates determined by management. If the cost of an investment exceeds its fair value, the Company evaluates, among other factors, general market conditions, credit quality of debt instrument issuers, and the extent to which the fair value is less than cost. To determine credit losses, a systematic methodology is employed that considers available quantitative and qualitative evidence. In addition, specific adverse conditions are considered related to the financial health of, and business outlook for, the investee. If the Company plans to sell the security or it is more likely than not that the Company will be required to sell the security before recovery, then a decline in fair value below cost is recorded as an impairment charge in other income (expense), net and a new cost basis in the investment is established. If market, industry, and/or investee conditions deteriorate, we may incur future impairments.

Investments in equity securities with readily determinable fair values are measured at fair value. Equity investments without readily determinable fair values are measured using the equity method or measured at cost with adjustments for observable changes in price or impairments (referred to as the measurement alternative). The Company performs a qualitative assessment on a periodic basis and recognize an impairment if there are sufficient indicators that the fair value of the investment is less than carrying value. Changes in value are recorded in other income (expense), net.

Accounts Receivable

Accounts receivable are stated net of the reserves for credit losses of $27,000 and $25,000 as of December 31,2025 and June 30, 2025, respectively. In accordance with ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), the Company recognizes an allowance for credit losses for trade receivables to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on the credit losses expected to arise over the life of the asset which includes consideration of past events and historical loss experience, current events and also future events based on our expectation as of the balance sheet date. Receivables are written off when the Company determines that such receivables are deemed uncollectible. The Company pools its receivables based on similar risk characteristics in estimating its expected credit losses. In situations where a receivable does not share the same risk characteristics with other receivables, the Company measures those receivables individually. The Company also continuously evaluates such pooling decisions and adjusts as needed from period to period as risk characteristics change.

The Company utilizes the loss rate method in determining its lifetime expected credit losses on its receivables. This method is used for calculating an estimate of losses based primarily on the Company’s historical loss experience. In determining its loss rates, the Company evaluates information related to its historical losses, adjusted for current conditions and further adjusted for the period of time that can be reasonably forecasted. Qualitative and quantitative adjustments related to current conditions and the reasonable and supportable forecast period consider all the following: past due receivables, the customer creditworthiness, changes in the terms of receivables, effect of other external forces such as competition, and legal and regulatory requirements on the level of estimated credit losses in the existing receivables.

Inventories

Inventories are valued at the lower of cost or net realizable value, with cost being determined on the first-in, first-out (FIFO) method. The reported net value of inventory includes finished saleable products, work-in-process and raw materials that will be sold or used in future periods. Inventory costs include raw materials, direct labor and overhead. The Company’s overhead expenses are applied based, in part, upon estimates of the proportion of those expenses that are related to procuring and storing raw materials as compared to the manufacture and assembly of finished products. These proportions, the method of their application, and the resulting overhead included in ending inventory, are based in part on subjective estimates and actual results could differ from those estimates.

The Company records a reserve for excess and slow-moving inventory, which represents any excess of the cost of the inventory over its estimated realizable value. This reserve is calculated using an estimated excess and slow-moving percentage applied to the inventory based on age, historical trends, product life cycle, requirements to support forecasted sales, and the ability to find alternate applications of its raw materials and to convert finished product into alternate versions of the same product to better match customer demand. In addition, and as necessary, the Company may establish specific reserves for future known or anticipated events. There is inherent professional judgment and subjectivity made by both production and engineering members of management in determining the estimated excess and slow-moving percentage (See Note 6).

The Company also regularly reviews the period over which its inventories will be converted to sales. Any inventories expected to convert to sales beyond 12 months from the balance sheet date are classified as non-current.

Property, Plant, and Equipment

Property, plant, and equipment are carried at cost less accumulated depreciation. Expenditures for maintenance and repairs are charged to expense as incurred; costs of major renewals and improvements are capitalized. At the time property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are eliminated from the asset and accumulated depreciation accounts and the profit or loss on such disposition is reflected in income.

Depreciation is recorded over the estimated service lives of the related assets using primarily the straight-line method. Amortization of leasehold improvements is calculated by using the straight-line method over the estimated useful life of the asset or lease term, whichever is shorter.

Long-Lived and Intangible Assets

Long-lived assets are amortized over their useful lives and are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets in question may not be recoverable. Impairment would be recorded in circumstances where undiscounted cash flows expected to be generated by an asset are less than the carrying value of that asset.

Intangible assets consisted of the follows (in thousands):

Amortization expense for intangible assets was approximately $74,000 and $79,000 for the three months ended December 31, 2025 and 2024, respectively and was approximately $149,000 and $157,000 for the six months ended December 31, 2025 and 2024, respectively. Amortization expense for each of the next five fiscal years is estimated to be as follows: 2027 - $283,000; 2028 - $269,000; 2029 - $210,000; 2030 - $202,000; and 2031 - $202,000. The weighted average remaining amortization period for intangible assets was 13.7 years and 14.1 years at December 31, 2025 and June 30, 2025, respectively.

Revenue Recognition

Revenue from contracts with customers is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue from all sales types is recognized at the transaction price, which is the amount we expect to be entitled to in exchange for transferring goods or providing services.

Equipment Revenue

Equipment revenue, which includes shipping and handling costs, is primarily generated from the sale of finished products to customers. Those sales predominantly contain a single performance obligation and revenue is recognized at a single point in time when ownership, risks and rewards transfer, which is typically the date of shipment of the related equipment when the product is picked up by the carrier or customer. A provision for product returns, credits and rebates is recorded as a reduction of equipment revenue in the same period the revenue is recognized.

The Company provides limited standard warranty for defective products, usually for a period of 24 to 36 months, and accepts returns for such defective products as well as for other limited circumstances. The Company also provides rebates to customers for meeting specified purchasing targets and other coupons or credits in limited circumstances. Reserves are established for the estimated returns, rebates and credits and such variable consideration is measured based on the most likely amount method.

The Company analyzes product sales returns and is able to make reasonable and reliable estimates of product returns based on several factors including actual returns and expected return data communicated to the Company by its customers.

Service Revenue

Service revenue is primarily generated from the sale of monthly cellular communication services. Those sales predominantly contain a single performance obligation and revenue is recognized ratably with the delivery of cellular communication service over the related monthly period, and when ownership, risks and rewards transfer to the customer.

The services are billed monthly, and customers have the right to cancel the cellular communication services at any time, however the contract with the customer does not provide for a refund.

Cost of Revenue

Cost of Equipment Revenue

Cost of equipment revenue is primarily comprised of direct materials and supplies consumed in the manufacturing of products, as well as manufacturing labor, depreciation expense and direct and indirect overhead expenses necessary to acquire and convert the purchased materials and supplies into finished products.

Cost of Service Revenue

Cost of service revenue includes the cost of operating our network operations center to manage and deliver telecommunication services.

Shipping and Handling Revenues and Costs

The Company records the amount billed to customers for shipping and handling in net revenue ($132,000 and $80,000 in the three months ended December 31, 2025 and 2024, respectively and $274,000 and $186,000 in the six months ended December 31, 2025 and 2024, respectively) and classifies the costs associated with these revenues in cost of sales ($365,000 and $353,000 in the three months ended December 31, 2025 and 2024, respectively and $844,000 and $743,000 in the six months ended December 31, 2025 and 2024, respectively).

Advertising and Promotional Costs

Advertising and promotional costs are included in "Selling, General and Administrative" (“SG&A”) expenses in the consolidated statements of income and are expensed as incurred. Advertising expense for the three months ended December 31, 2025 and 2024 was $916,000 each period. Advertising expense for the six months ended December 31, 2025 and 2024 was $1,851,000 and $1,806,000, respectively.

Research and Development Costs

Research and development (“R&D”) costs incurred by the Company are charged to expense as incurred and are included in operating expenses in the consolidated statements of income.

Income Taxes

The Company records provisions for income taxes in the consolidated financial statements using the asset and liability method. Under this method, income tax liabilities or receivables are recognized for the current year, in addition deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. When necessary, a valuation allowance is recorded to reduce deferred tax assets to the net amount that is believed is more likely than not to be realized. That assessment considers the recognition of deferred tax assets on a jurisdictional basis. Accordingly, in assessing the future taxable income on a jurisdictional basis, the Company considers the effect of the transfer pricing policies on that income.

The Company recognizes tax benefits from uncertain tax positions only if it believes that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Company’s policy is to adjust these unrecognized tax benefits in the period when facts and circumstances change, such as the closing of a tax audit, the expiration of statute of limitation for a relevant taxing authority to examine a tax position, or when additional information becomes available. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the provision for income taxes in the period in which such determination is made and could have a material impact on the financial condition and operating results. The provision for income taxes includes the effects of any accruals that we believe are appropriate, as well as the related interest and penalties.

Legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act introduced the global intangible low-taxed income (“GILTI”) provisions effective in 2018, which generally impose a tax on the net income earned by foreign subsidiaries of a U.S. company in excess of a deemed return on their tangible assets. The Company recognizes the tax on GILTI as a period cost when the tax is incurred.

Net Income per Share

Basic net income per common share (Basic EPS) is computed by dividing net income by the weighted average number of common shares outstanding. Diluted net income per common share (Diluted EPS) is computed by dividing net income by the weighted average number of common shares and dilutive common share equivalents and convertible securities then outstanding.

The following provides a reconciliation of information used in calculating the per share amounts for the three months ended December 31, 2025 and 2024 (in thousands, except per share data):

Options to purchase 20,000 and 120,000 shares of common stock were excluded for the three months ended December 31, 2025 and 2024, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period.

The following provides a reconciliation of information used in calculating the per share amounts for the six months ended December 31, 2025 and 2024 (in thousands, except per share data):

Options to purchase 70,000 shares of common stock were excluded for the both the six months ended December 31, 2025 and 2024, respectively, and were not included in the computation of Diluted EPS because their inclusion would be anti-dilutive. These options were still outstanding at the end of the period.

Stock-Based Compensation

The Company has established five share incentive programs as discussed in Note 10.

The Company measures stock-based compensation at the grant date based on the fair value of the award, and estimates the fair value of each option granted on the date of the grant using the Black-Scholes option-pricing model, which contains uncertainties and requires us to estimate the risk-free interest rate, expected term, expected stock price volatility and dividend yield. The expected term for options granted is estimated using our historical experience, including information related to options we have granted.

The Company has elected to treat awards with only service conditions and with graded vesting as one award, and recognizes compensation costs for share-based awards on a straight-line basis, net of actual forfeitures, over the requisite service period of the award, usually the vesting period, which is generally four orfive years.

Foreign Currency

The Company has determined the functional currency of all foreign subsidiaries is the U.S. Dollar. All foreign operations are considered a direct and integral part or extension of the Company’s operations. The day-to-day operations of all foreign subsidiaries are dependent on the economic environment of the U.S. Dollar. Therefore, no realized and unrealized gains and losses associated with foreign currency translation are recorded for the three and six months ended December 31, 2025 or 2024.

Segment Reporting

The Company operates its business underone operating segment, which is also its reportable segment. The Company's Chief Operating Decision maker (“CODM”), who is our President and Chief Operating Officer, reviews financial information presented at the consolidated level and decides how to allocate resources based on financial metrics, including net income. The measure of

segment assets is reported on the balance sheet as total consolidated assets. The CODM uses such financial metrics, including net income, to evaluate income generated from segment assets (return on assets) in deciding whether to reinvest profits or allocate to other parts of the organization, such as working capital needs, mandatory and discretionary capital expenditures or other growth opportunities that may arise that are in the Company’s best interest and the best interest of the stockholders. See Note 14 – Segment and Geographical Data for additional accounting policies and disclosures.

Leases

The Company determines at contract inception if an arrangement is a lease, or contains a lease, of an identified asset for which the Company has the right to obtain substantially all of the economic benefits from its use and the right to direct its use. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term, while lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at lease commencement date based on the present value of lease payments over the lease term. The implicit discount rate in the Company’s leases generally cannot readily be determined, and therefore the Company uses its incremental borrowing rate based on information available at lease commencement date in determining the present value of future payments. If the Company has options to renew or terminate certain leases, those options are included in the determination of lease term when it is reasonably certain that the Company will exercise such options. The Company does not separate lease and non-lease components in determining ROU assets or lease liabilities for real estate leases. Additionally, the Company does not recognize ROU assets or lease liabilities for leases with original terms or renewals of one year or less. See Note 13 – Commitments and Contingencies; for additional accounting policies and disclosures.

Legal and Other Contingencies

The outcomes of legal proceedings and claims brought against us are subject to significant uncertainty. An estimated loss from a loss contingency such as a legal proceeding or claim is accrued by a charge to income if it is probable that an asset has been impaired, or a liability has been incurred and the amount of the loss can be reasonably estimated. In determining whether a loss should be accrued we evaluate, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. Changes in these factors could materially impact our consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In October 2023, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2023-06, Disclosure Improvements:Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,* which modifies the disclosure or presentation requirements of a variety of Topics in the Codification. Among the various codification amendments, Topic 470Debt*is applicable to the Company which requires the disclosure of amounts, terms and weighted-average interest rates of unused lines of credit. The effective date is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirement by that date, with early adoption prohibited. The adoption of this new standard will not have a material impact on our financial statements and related disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes:Improvements to Income Tax Disclosures,* *which requires on an annual basis to (1) disclose specific categories in the rate reconciliation, (2) provide additional information for reconciling items that meet a quantitative threshold, and (3) income taxes paid disaggregated by jurisdiction. This guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the impact that this guidance may have on its financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement:Reporting Comprehensive Income - Expense Disaggregation Disclosures, Disaggregation of Income Statement Expenses, which improves disclosure requirements and mandates enhanced transparency about the types of expenses in commonly presented expense captions in financial statements. This guidance is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted and is effective on either a prospective basis or retrospective basis. The Company is currently evaluating the impact that this guidance may have on our financial statements and related disclosures.

In July 2025, the FASB issued ASU No. 2025-05 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, which amends the manner in which credit losses for accounts receivable and contract assets

are determined. For public companies, the guidance introduces a practical expedient for estimating expected credit losses on current accounts receivable and current contract assets. Under this expedient, entities may assume that conditions existing at the balance sheet date will persist for the remaining life of the asset, which simplifies the estimation process by eliminating the need to forecast future economic conditions for these short-term assets. This guidance is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on its financial statements and related disclosures.

In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting tor Internal-Use Software. The amendments update the framework for recognizing and disclosing costs related to software developed for internal use, including costs associated with website development. The amendments are effective for annual reporting periods beginning after December 15, 2027, and interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual reporting period. The Company is currently evaluating the impact of this guidance on its financial statements and related disclosures.

The Company is evaluating other pronouncements recently issued but not yet adopted. The adoption of these pronouncements is not expected to have a material impact on our consolidated financial statements.

NOTE 2 – Revenue Recognition and Contracts with Customers

The Company is engaged in the development, manufacture, and distribution of security products, encompassing access control systems, door security products, intrusion and fire alarm systems, alarm communication services, and video surveillance products for commercial and residential use. The Company also provides wireless communication service, on a monthly basis, to dealers and installers of intrusion and fire alarm systems. These products and services are used for commercial, residential, institutional, industrial and governmental applications, and are sold primarily to independent distributors, dealers and installers of security equipment. Sales to unaffiliated customers are primarily shipped from the United States.

As of December 31, 2025 and June 30, 2025, the Company included refund liabilities of approximately $3,707,000 and $4,790,000, respectively, in current liabilities. As of December 31, 2025 and June 30, 2025, the Company included return-related assets of approximately $1,003,000 and $1,152,000, respectively, in other current assets.

As a percentage of gross revenue, returns, rebates and allowances were 4% for both the three months ended December 31, 2025 and 2024, respectively. As a percentage of gross revenue, returns, rebates and allowances were 4% and 7% for the six months ended December 31, 2025 and 2024, respectively.

The Company disaggregates revenue from contracts with customers into major product lines. The Company determines that disaggregating revenue into these categories achieves the disclosure objective to depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. As noted in the accounting policy footnote, the Company’s business consists ofone operating segment. Following is the disaggregation of revenues based on major product lines (in thousands):

NOTE 3 – Business and Credit Concentrations

Financial instruments that potentially subject the Company to a concentration of credit risk mainly consist of cash equivalents, short-term investments and accounts receivable. Our cash equivalents and short-term investments primarily consist of government securities and money market funds which are held and managed by high credit quality financial institutions.

The Company hadone customer that comprised 15% and 13% of the accounts receivable balance as of December 31, 2025 and June 30, 2025, respectively. The Company hadone additional customer that comprised 16% accounts receivable balance as of December 31, 2025 anda different customer that comprised of 11% accounts receivable balance as of June 30, 2025. Sales to any customer did not exceed 10% of net revenues during the three and six months ended December 31, 2025 and 2024, respectively.

NOTE 4 – Fair Value Measurement

Fair value is the price that would be received for an asset or the amount paid to transfer a liability in an orderly transaction between market participants. The Company is required to classify certain assets and liabilities based on the following fair value hierarchy:

A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company has evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions or estimation methodologies could have a significant effect on the estimated fair value amounts.

The following table presents the Company’s assets that were measured at fair value on a recurring basis at December 31, 2025 and June 30, 2025, respectively (in thousands):

The Company’s investments classified as Level 1 are based on quoted prices that are available in active markets, as well as certificates of deposits and time deposits that are classified as Level 1 due to their short-term nature.

For the three ending December 31, 2025 and 2024, there wereno transfers between Levels 1 and 2 investments andno transfers in or out of Level 3.

NOTE 5 – Marketable Securities

A summary of the fair value of the Company’s investment in marketable securities as of December 31, 2025 and June 30, 2025 is as follows:

Investments in Equity Securities

The disaggregated net gains and losses on the equity securities recognized within the accompanying condensed consolidated statements of income for the three and six months ended December 31, 2025 and 2024, are as follows (in thousands):

The following tables summarize the Company’s investments in equity securities at December 31, 2025 and June 30, 2025, respectively (in thousands):

Investment income is recognized when earned and consists principally of dividend income from fixed income mutual funds. Realized gains and losses on sales of investments are determined on a specific identification basis.

Investments in Debt Securities

The following tables summarize the Company’s investments in debt securities at December 31, 2025 and June 30, 2025 (in thousands):

The debt investments all mature within one year or less, and the Company didnot recognize any credit or non-credit related losses related to its debt securities during the three and six months ended December 31, 2025 and 2024.

NOTE 6 - Inventories

Inventories, net of reserves are valued at lower of cost (first-in, first-out method) or net realizable value. Inventories, net of reserves consist of the following (in thousands):

The reserve for excess and slow-moving inventory, which reduces inventory in our consolidated balance sheets were $5,388,000 and $5,515,000 as of December 31, 2025 and June 30, 2025, respectively.

NOTE 7 – Property, Plant, and Equipment

Property, plant and equipment consist of the following (in thousands):

Depreciation and amortization expense on property, plant, and equipment was approximately $488,000 and $506,000 for the three months ended December 31, 2025 and 2024, respectively. Depreciation and amortization expense on property, plant, and equipment was approximately $986,000 and $976,000 for the six months ended December 31, 2025 and 2024, respectively

NOTE 8 - Income Taxes

The income tax provision is calculated using an estimated annual effective tax rate based upon estimates of annual income, permanent items, statutory tax rates and planned tax strategies in the various jurisdictions in which the Company operates, except that certain discrete items such as the resolution of uncertain tax positions and stock-based accounting income tax benefits are treated separately.

Income tax expense included on our accompanying consolidated statements of income is as follows:

The difference between the U.S. statutory tax rate of 21% and the effective tax rate in both periods is primarily due to lower tax rates in foreign jurisdictions and the related effect of global intangible low-taxed income (“GILTI”), tax benefit of R&D credits, offset by state and local income taxes and certain nondeductible expenses income.

On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act ("OBBBA"). The OBBBA preserves the 21% U.S. Federal statutory tax rate and makes a favorable change to the business interest expense limitation. Further, the OBBBA also makes key elements of the Tax Cuts and Jobs Act permanent, including 100% bonus depreciation, domestic research cost expensing, and various expiring international provisions (with some modifications). Pursuant to ASC 740, changes in tax rates and tax law are required to be recognized in the period in which the legislation is enacted. The Company has completed its evaluation of the impact of this legislation and has determined that the OBBBA will defer the payment of a significant portion of our current federal tax but will not have a material impact on its Fiscal 2026 financial statements.

We file a consolidated U.S. income tax return and tax returns in certain state and local and foreign jurisdictions. As of December 31, 2025, fiscal years 2022 and forward are still open for examination. In addition, the Company has a wholly-owned subsidiary which operates in a Free Zone in the Dominican Republic (“DR”) and is exempt from DR income tax.

NOTE 9 - Debt

The Company has available a$20 million revolving credit line (the “Line”) with its primary bank, HSBC Bank USA National Association (“HSBC”), which expires on February 9, 2029. Borrowings on the Line bear interest at the Secured Overnight Financing Rate (SOFR) benchmark rate plus 1.2645% to 1.3645%, depending on the Fixed Charge Coverage Ratio (as defined), which is to be measured and adjusted quarterly.

Leases

Our lease obligation consists of a 99-year lease, entered into by one of the Company’s foreign subsidiaries, for approximately four acres of land in the Dominican Republic on which the Company’s principal production facility is located. The lease, which commenced on April 26, 1993 and expires in 2092, initially had an annual base rent of approximately $235,000 plus $53,000 in annual service charges. On September 14, 2022, a lease modification was executed which provides for an annual base rent of $235,000 plus $105,000 in annual service charges. The service charges increase 2% annually over the remaining life of the lease. The modification resulted in a remeasurement of the operating lease asset and liability and the effect was a reduction to the asset and liability of $1.3 million.

Operating leases are included in operating lease right-of-use assets, accrued expenses and operating lease liabilities, non-current on our condensed consolidated balance sheets.

For the three months ended December 31, 2025 and 2024 cash payments against operating lease liabilities totaled $87,000 and $115,000, respectively. For the six months ended December 31, 2025 and 2024 cash payments against operating lease liabilities totaled $173,000 and $172,000, respectively.

Litigation

On August 29, 2023, a purported class action, brought on behalf of a putative class who acquired publicly traded NAPCO securities between November 7, 2022 and August 18, 2023, was filed in the United States District Court for the Eastern District of New York against the Company, its Chairman and Chief Executive Officer, and its former Chief Financial Officer (who is currently the President and Chief Operating Officer). The action, captioned Zornberg v. NAPCO Security Technologies, Inc. et al., asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with statements made in the Company’s quarterly reports and earnings releases during the period of November 7, 2022 through May 8, 2023. A lead plaintiff was appointed in November 2023 and lead plaintiff filed an Amended Complaint on February 16, 2024. The Amended Complaint added claims under Sections 11, 12, and 15 of the Securities Act of 1933 in connection with the secondary public offering in February 2023. These additional claims were brought against the defendants named in the initial complaint, as well as the directors who allegedly signed the offering materials (prospectuses and a registration statement in connection with the offering), and the underwriters for the offering. Defendants filed a motion to dismiss the Amended Complaint on April 26, 2024. On April 11, 2025, the Court granted in part and

denied in part the motion to dismiss. The Section 11 and Section 12 claims brought against the individual defendants were dismissed; the remaining claims survived the motion to dismiss. On May 12, 2025, Defendants filed Answers to the Amended Complaint. On September 29, 2025, the plaintiffs moved for class certification of both the Exchange Act and remaining Securities Act claims. On October 17, 2025, pursuant to a joint letter and stipulation filed by all the parties, the Court dismissed the Securities Act claims with prejudice and certified a class with respect to the Exchange Act claims. The Company believes it has meritorious defenses and intends to vigorously defend against the Action.

On November 26, 2024, a putative derivative lawsuit captioned Minzer v. Soloway, et al., Case No. 2024-1218, was filed in the Court of Chancery in the State of Delaware against the Company’s Chairman and Chief Executive Officer, former Chief Financial Officer (who is currently the President and Chief Operating Officer), and certain current and former directors. The Company is a “Nominal Defendant” in the lawsuit. After the Company and the individual defendants moved to dismiss or stay the action, plaintiffs filed an Amended Complaint on June 12, 2025. The Amended Complaint alleges, among other things, that the individual defendants breached their fiduciary duties and aided and abetted breach of fiduciary duties by allowing the Company to remain with ineffective internal controls over financial reporting and inventory and by allowing for the dissemination of false and misleading financial information in public filings. The Amended Complaint also brings breach of fiduciary duty and unjust enrichment claims in connection with stock sales by the Company’s Chairman and Chief Executive Officer and its former Chief Financial Officer (who is currently the President and Chief Operating Officer) and seeks indemnity and contribution. The Company’s status as a “Nominal Defendant” in the action reflects the fact that the lawsuit is maintained by the named plaintiff on behalf of the Company and that the plaintiff seeks damages on the Company’s behalf. Defendants believe that there are substantial defenses to the claims asserted and filed a second motion to dismiss or stay the case on August 22, 2025. Oral argument on that motion is scheduled for May 7, 2026.

On March 31, 2025, the Company received a subpoena from the Securities and Exchange Commission (“SEC”).

On April 25, 2025, a purported class action, brought on behalf of a putative class who acquired publicly traded NAPCO securities between February 5, 2024 and February 3, 2025, was filed in the United States District Court for the Eastern District of New York against the Company, its Chairman and Chief Executive Officer, and its former Chief Financial Officer (who is currently the President and Chief Operating Officer). The action, captioned Patel v. NAPCO Security Technologies, Inc. et al., asserts securities fraud claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with statements made in quarterly earnings releases and calls during the period of February 5, 2024 through February 3, 2025. The Court has not yet appointed a lead plaintiff. The Company believes it has meritorious defenses and intends to vigorously defend against the Action.

With respect to all litigation and related matters, the Company records a liability when the Company believes it is probable that a liability has been incurred and the amount can be reasonably estimated. As of the end of the period covered by this report, due to the early stage of the case the Company is not able to estimate any range of potential loss related to this matter and has not recorded any liability. It is possible that the Company could be required to pay damages (in excess of insurance coverages), incur other costs or establish accruals in amounts that could not be reasonably estimated as of the end of the period covered by this report.
