NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

​

1. Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of OSI Systems, Inc. and our subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The condensed consolidated financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded in accordance with SEC rules and regulations and GAAP applicable to interim unaudited financial statements. Accordingly, the condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for audited annual financial statements. In the opinion of management, the condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. These unaudited condensed consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 filed with the SEC. The results of operations for the three months ended September 30, 2025 are not necessarily indicative of the operating results to be expected for the full 2026 fiscal year or any future periods.

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 the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales, costs of sales and expenses during the reporting period. The most significant of these estimates and assumptions for our company relate to contract revenue, fair values of assets acquired and liabilities assumed in business combinations, values for inventories reported at lower of cost or net realizable value, stock-based compensation expense, income taxes, accrued warranty costs, contingent consideration, allowance for doubtful accounts, and the recoverability, useful lives and valuation of recorded amounts of long-lived assets, identifiable intangible assets and goodwill. Changes in estimates are reflected in the periods during which they become known. Due to the inherent uncertainty involved in making estimates, our actual amounts reported in future periods could differ materially from estimated amounts.

​

Earnings Per Share Computations

​

We compute basic earnings per share by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. We compute diluted earnings per share by dividing net income available to common stockholders by the sum of the weighted average number of common shares and dilutive potential common shares outstanding during the period. Potential common shares consist of the shares issuable upon the exercise of stock options and restricted stock unit awards under the treasury stock method. The underlying equity component of the 2.25% convertible senior notes due 2029 (the “2029 Notes”) discussed in Note 8 to the condensed consolidated financial statements will have a net impact on diluted earnings per share when the average price of our common stock exceeds the conversion price of $191.98 because the principal amount of the 2029 Notes will be settled in cash upon conversion. There was a dilutive effect of the 2029 Notes as set forth in the table below for the three months ended September 30, 2025.

​

Cash and Cash Equivalents

​

We consider all highly liquid investments with maturities of three months or less as of the acquisition date to be cash equivalents.

Our cash and cash equivalents totaled $124.4 million at September 30, 2025. Of this amount, approximately 64% was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in India, the United Kingdom, Singapore, and Canada and to a lesser extent Malaysia, Australia, and Indonesia, among other countries. We have cash holdings in financial institutions that exceed insured limits for such financial institutions; however, we mitigate this risk by utilizing international financial institutions which we believe to be of high credit quality.

​

Fair Value of Financial Instruments

​

Our financial instruments consist primarily of cash and cash equivalents, insurance company contracts, accounts receivable, accounts payable, debt instruments, an interest rate swap contract and foreign currency forward contracts. The carrying values of financial instruments, other than long-term debt instruments and our interest rate swap contract, are representative of their fair values due to their short-term maturities. The carrying values of our long-term debt instruments are considered to approximate their fair values because the interest rates of these instruments are variable or comparable to current rates for financing available to us. The fair values of our foreign currency forward contracts were not significant as of June 30, 2025 or as of September 30, 2025.

​

Fair value is the price that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The “Level 1” category includes assets and liabilities at quoted prices in active markets for identical assets and liabilities. The “Level 2” category includes assets and liabilities from observable inputs other than quoted market prices. The “Level 3” category includes assets and liabilities for which valuation techniques are unobservable and significant to the fair value measurement. Our contingent payment obligations related to acquisitions, which are further discussed in Note 10 to the condensed consolidated financial statements, are in the “Level 3” category for valuation purposes.

​

The fair values of our financial assets and liabilities are categorized as follows (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | June 30, 2025 |  | September 30, 2025

Derivative Instruments and Hedging Activity

​

Our use of derivatives consists of foreign currency forward contracts and an interest rate swap agreement. Our foreign currency forward contracts are utilized to partially mitigate certain balance sheet exposures or used as a net investment hedge to protect against potential changes resulting from short-term foreign currency fluctuations. These contracts have original maturities of up to three months. We also manage our risk to changes in interest rates using derivative instruments. We use fixed interest rate swaps to effectively convert a portion of the variable interest rate payments to fixed interest rate payments. We do not use hedging instruments for speculative purposes.

​

The net gains or losses from our foreign currency forward contracts, which are not designated as hedge instruments, are reported in the consolidated statements of operations, and the amounts reported for the three months ended September 30, 2024 and 2025 were not significant. The fair value of our foreign currency forward contracts is estimated using a standard valuation model and market-based observable inputs over the contractual term. Unrealized gains are recognized as assets and unrealized losses are recognized as liabilities. As of June 30, 2025 and September 30, 2025, we held foreign currency forward contracts with notional amounts totaling $99.9 million and $113.4 million, respectively. Unrealized gains and losses from our foreign currency forward contracts as of June 30, 2025 and September 30, 2025 were not significant.

Our interest rate swap agreement was entered into to improve the predictability of cash flows from interest payments related to our variable, Secured Overnight Financing Rate (“SOFR”)-based debt. The interest rate swap matures in December 2026. The interest rate swap is considered an effective cash flow hedge, and as a result, the net gains or losses on such instrument are reported as a component of other comprehensive income (loss) in our consolidated financial statements and are reclassified as net income when the underlying hedged interest impacts earnings. A qualitative and quantitative assessment of the interest rate swap hedge effectiveness is performed on a quarterly basis, unless facts and circumstances indicate that the hedge may no longer be highly effective.

As of June 30, 2025 and September 30, 2025, the notional amount of the derivative instruments designated as an interest rate swap hedge was $175 million. The fair value of the interest rate swap agreement as of June 30, 2025 and September 30, 2025 is recorded in Other assets within the consolidated balance sheet.

The effect of the cash flow hedges on other comprehensive income (loss) and earnings for the periods presented was as follows:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Months Ended September 30,
​ | ​ | 2024 |  | 2025
Total interest and other expense, net presented in the condensed consolidated statements of operations in which the effects of cash flow hedges are recorded | ​ | $ | (7,359) | ​ | $ | (7,398)
Loss recognized in other comprehensive income (loss), net of tax | ​ | ​ | (3,220) | ​ | ​ | (239)
Benefit reclassified from accumulated other comprehensive loss to interest expense, net | ​ | ​ | 900 | ​ | ​ | 463

​

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) and other regulatory bodies that are adopted as of the specified effective dates. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on our Consolidated Financial Statements upon adoption. There were no new pronouncements adopted in the first quarter of fiscal year 2026.

Accounting Guidance Not Yet Adopted

In December 2023, the FASB issued Accounting Standards Update 2023-09, “Improvements to Income Tax Disclosures” (“ASU 2023-09”), which provides for additional disclosures primarily related to income tax rate reconciliations and income taxes paid. ASU 2023-09 requires entities to annually disclose the income tax rate reconciliation using both amounts and percentages, considering several categories of reconciling items, including state and local income taxes, foreign tax effects, tax credits and nontaxable or nondeductible items, among others. Disclosure of the reconciling items is subject to a quantitative threshold and disaggregation by nature and jurisdiction. ASU 2023-09 also requires entities to disclose net income taxes paid to or received from federal, state and foreign jurisdictions, as well as by individual jurisdiction, subject to a five percent quantitative threshold. ASU 2023-09 may be adopted on a prospective or retrospective basis and is effective for fiscal years beginning after December 15, 2024 with early adoption permitted. We are evaluating the potential impact of ASU 2023-09 on disclosures in our Consolidated Financial Statements which is effective beginning with our Form 10-K for fiscal year 2026.

In November 2024, the FASB issued a new standard to expand disclosures about income statement expenses. The guidance requires disaggregation of certain costs and expenses included in each relevant expense caption on our consolidated income statements in a separate note to the financial statements at each interim and annual reporting period, including amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The standard will be effective for us beginning with our Form 10-K for fiscal year 2028 and interim periods thereafter, with early adoption permitted. We are currently evaluating the impact of this standard on our disclosures.

In September 2025, the FASB issued Accounting Standards Update 2025-06 “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software” (“ASU 2025-06”) which modernizes the accounting for internal-use software to current development practices, clarifies when to begin capitalizing costs and enhances disclosure requirements. This update is effective for interim and annual periods beginning after December 15, 2027, with early adoption permitted. We are currently evaluating the impact of this standard on our accounting for internal-use software and related disclosure requirements.

2. Business Combinations

Under Accounting Standards Codification Topic 805, Business Combinations (“ASC 805”), the acquisition method of accounting requires us to record assets acquired less liabilities assumed from an acquisition at their estimated fair values at the date of acquisition. Any excess of the total estimated purchase price over the estimated fair value of the net assets acquired should be recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customers, acquired technology, trade names, useful lives and discount rates. Management’s estimates of fair value are based on assumptions which are believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period for fair value, which is up to one year from the acquisition date, as additional information that existed at the acquisition date becomes available, we may record adjustments to the preliminary assets acquired and liabilities assumed. Upon the conclusion of the measurement period, any subsequent adjustments are included in earnings.

Fiscal Year 2025 Business Acquisitions

In September 2024, we (through our Security division) acquired 100% of the shares of common stock of a privately held provider of critical military, space and surveillance solutions to expand our customer base and offer additional products and services for existing customers, for approximately $76.0 million, plus up to $24.0 million in potential contingent consideration. We paid $75.5 million in cash at the closing of the transaction and recorded a holdback liability of $0.5 million which is expected to be released in 2030. The cash paid for this acquisition was financed with borrowings from our credit facility. The acquisition date fair value of the contingent consideration was $9.7 million, which, when combined with the amount of cash paid at close and the holdback amount, resulted in total purchase consideration of $85.7 million being allocated to the preliminary fair value of assets acquired and liabilities assumed. The acquisition date fair value of total assets acquired, including measurement period adjustments, was $113.9 million which comprised accounts receivable of $26.1 million, inventory and other current assets of $2.7 million, property and equipment of $7.0 million, goodwill of $30.7 million, other intangible assets of $47.3 million and other noncurrent assets of $0.1 million. Goodwill includes the value of the assembled workforce, new customers and other future economic benefits which do not qualify for separate recognition. The goodwill recognized for this business acquisition is not deductible for income tax purposes. Other intangible assets include amortizable intangible assets of $36.7 million with amortization periods of 7 to 10 years and an indefinite-lived intangible asset of $8.1 million. The acquisition date fair value of total liabilities assumed, including measurement period adjustments, was $28.2 million, which includes a deferred tax liability of $7.3 million that was recognized primarily due to the acquisition of other intangible assets. During the three months ended September 30, 2025, we recorded measurement period adjustments which decreased goodwill by $1.4 million due to a decrease in deferred income taxes of $1.8 million and an increase in intangible assets of $0.1 million, which were partially offset by a decrease in accounts receivable of $0.5 million. The measurement period adjustments did not have a significant impact on the consolidated statement of operations.

In April 2025, we (through our Security Division) acquired a privately held provider of engineering and structural component services for approximately $1.3 million, plus up to $0.9 million in potential contingent consideration. The acquisition was financed with cash on hand. The goodwill recognized for this business acquisition is not deductible for income tax purposes.

​

Amortization expense related to intangible assets was $4.8 million and $4.9 million for the three months ended September 30, 2024 and 2025, respectively.

​

At September 30, 2025, the estimated future amortization expense for amortizable intangible assets was as follows (in thousands):

​

Fiscal Year

​

​ | ​ | ​ | ​
2026 (remaining 9 months) |  | $ | 13,103
2027 | ​ |  | 14,817
2028 | ​ |  | 14,586
2029 | ​ |  | 14,318
2030 | ​ | ​ | 13,092
Thereafter | ​ |  | 73,084
Total | ​ | $ | 143,000

​

Software development costs for software products incurred before establishing technological feasibility are charged to operations. Software development costs incurred after establishing technological feasibility are capitalized on a product-by-product basis until the product is available for general release to customers at which time amortization begins. Annual amortization, charged to cost of goods sold, is the amount computed using the ratio that current revenues for a product bear to the total current and anticipated future revenues for that product. In the event that future revenues are not estimable, such costs are amortized on a straight-line basis over the remaining estimated economic life of the product. Amortizable assets that have not yet begun to be amortized are included in Thereafter in the table above. For each of the three month periods ended September 30, 2024 and 2025, we capitalized software development costs of $4.2 million.

5. Contract Assets and Liabilities

​

We enter into contracts to sell products and provide services, and we recognize contract assets and liabilities that arise from these transactions. We recognize revenue and corresponding accounts receivable according to ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). When we recognize revenue in advance of the point in time at which contracts give us the right to invoice a customer, we record this as unbilled revenue, which is included in accounts receivable, net, on the consolidated balance sheets. We may also receive consideration, per the terms of a contract, from customers prior to transferring control of goods to the customer. We record customer deposits as contract liabilities. Additionally, we may receive payments, most typically under service and warranty contracts, at the onset of the contract and before services have been performed. In such instances, we record a deferred revenue liability in either Other accrued expenses and current liabilities or Other long-term liabilities. We recognize these contract liabilities as sales after all revenue recognition criteria are met.

​

The table below shows the balance of contract assets and liabilities as of June 30, 2025 and September 30, 2025, including the change between such dates. There were no substantial non-current contract assets for the periods presented.

Deferred revenue—long-term | ​ |  | 18,856 | ​ | ​ | 18,619 | ​ | ​ | (237) | ​ | (1) | %

​

Contract Assets. Contract assets decreased by approximately $59.3 million primarily due to achievement of certain milestones in our Security division giving us the right to invoice customers.

​

Remaining Performance Obligations. Remaining performance obligations related to ASC 606 represent the portion of the transaction price allocated to performance obligations under an original contract with a term greater than one year which are fully or partially unsatisfied at the end of the period. As of September 30, 2025, the portion of the transaction price allocated to remaining performance obligations was approximately $875.6 million. We expect to recognize revenue on approximately 55% of the remaining performance obligations over the next 12 months, and the remainder is expected to be recognized thereafter. During the three months ended September 30, 2025, we recognized revenue of $36.7 million from contract liabilities existing at the beginning of the period.

​

Practical Expedients. In cases where we are responsible for shipping after the customer has obtained control of the goods, we have elected to treat the shipping activities as fulfillment activities rather than as separate performance obligations. Additionally, we have elected to capitalize the cost to obtain a contract only if the period of amortization would be longer than one year. We only give consideration to whether a customer agreement has a financing component if the period of time between transfer of goods and services and customer payment is greater than one year.

7. Restructuring and Other Charges

​

We endeavor to align our global capacity and infrastructure with demand by our customers and to effectively integrate acquisitions and thereby improve our operational efficiency.

​

During the three months ended September 30, 2025, we recognized $2.7 million in restructuring and other charges, which included $2.4 million primarily for non-recurring charges in the Security and Healthcare divisions and $0.3 million for employee terminations.

​

During the three months ended September 30, 2024, we recognized $1.2 million in restructuring and other charges, which included $0.6 million in employee terminations, $0.2 million for facility closure costs for operational efficiency activities, and $0.4 million in acquisition related costs.

8. Borrowings

​

Revolving Credit Facility

​

In July 2025 we amended and extended our revolving credit facility, now maturing in July 2030, to increase the limit from $600 million to $725 million and replaced the $128.1 million term loan with a $100.0 million term loan which were accounted for as a debt modification. The sub-limit for letters of credit was increased from $300 million to $350 million, which includes up to $300 million for borrowings in certain foreign currencies. Under certain circumstances and subject to certain conditions, we have the ability to increase the revolving credit facility by an amount equal to the greater of $300 million or such amount as would not cause our secured leverage ratio to exceed a specified level. Other enhancements include the permitted securitization of certain qualifying assets of up to $100 million.

Borrowings under the facility bore interest at SOFR plus a margin of 1.25% as of September 30, 2025 (which margin can range from 1.0% to 1.75% based on our consolidated net leverage ratio as defined in the credit facility). Letters of credit reduce the amount available to borrow under the credit facility by their face value amount. The unused portion of the facility bore a commitment fee of 0.15% as of September 30, 2025 (which fee can range from 0.10% to 0.25% based on our consolidated net leverage ratio as defined in the credit facility). Our borrowings under the credit agreement are guaranteed by certain of our U.S.-based subsidiaries and are secured by substantially all of our assets and substantially all the assets of certain of our subsidiaries. The credit facility contains various representations and warranties, affirmative, negative and financial covenants and events of default. As of September 30, 2025, there were $252.1 million of borrowings outstanding under the revolving credit facility, $95.4 million outstanding under the letters of credit sub-facility, and $98.8 million outstanding under the term loan. As of September 30, 2025, the amount available to borrow under the revolving credit facility was $377.5 million. Loan amounts under the revolving credit facility may be borrowed, repaid and re-borrowed during the term. The principal amount of each loan is due and payable in full on the maturity date. We have the right to repay each loan in whole or in part from time to time without penalty. It is our practice to routinely borrow and repay several times per year under the revolving facility and therefore, borrowings under the revolving credit facility are included in current liabilities. As of September 30, 2025, we were in compliance with all financial covenants under this credit facility. In September 2022, we entered into an interest rate swap agreement in order to mitigate the interest rate risk on a portion of the interest payments expected to be made on the borrowings outstanding under the revolving credit facility and term loan. Refer to Note 1 for further information relating to the interest rate swap agreement.

2.25% Convertible Senior Notes Due 2029

​

In July 2024, we issued an aggregate of $350.0 million principal amount of 2.25% convertible senior notes due in August 2029 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, at an issuance price equal to 97.5% of the principal amount. The 2029 Notes were issued pursuant to and are governed by an indenture dated July 19, 2024. The proceeds from the issuance of the 2029 Notes were $340.4 million, net of the issuance discount and debt issuance costs.

The 2029 Notes are unsecured obligations which bear regular interest at 2.25% per annum payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2025. The 2029 Notes will mature on August 1, 2029, unless repurchased, redeemed, or converted in accordance with their terms prior to such date. The 2029 Notes are convertible into a combination of cash and shares of our common stock, at an initial conversion rate of 5.2090 shares of common stock per $1,000 principal amount of 2029 Notes, which is equivalent to an initial conversion price of approximately $191.98 per share of our common stock. The default settlement method is a combination settlement with a specified dollar amount of $1,000 per $1,000 principal amount of notes. The conversion rate is subject to customary adjustments for certain dilutive events. We may redeem for cash all or any portion of the 2029 Notes, at our option, on or after August 6, 2027 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days at a redemption price equal to 100% of the principal amount of the 2029 Notes to be redeemed, plus accrued and unpaid interest up to the day before the redemption date. The holders of the 2029 Notes may require us to repurchase the 2029 Notes upon the occurrence of certain fundamental change transactions at a redemption price equal to 100% of the principal amount of the 2029 Notes redeemed, plus accrued and unpaid interest up to the day before the redemption date.

Holders of the 2029 Notes may, at their option, convert all or a portion of their 2029 Notes prior to May 1, 2029, in multiples of $1,000 principal amounts, only (i) during any calendar quarter if our common stock price exceeds 130% of the conversion price for at least 20 trading days during the 30 consecutive trading days at the end of the prior calendar quarter, (ii) during the five consecutive business days immediately after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of the 2029 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price per share of our common stock on such trading day and the conversion rate on such trading day, (iii) upon the occurrence of specified corporate events or certain distributions on our common stock; or (iv) if we call any or all of the 2029 Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date, but only with respect to the 2029 Notes called for redemption.

On or after May 1, 2029, the 2029 Notes are convertible by the holders thereof at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. Holders of the 2029 Notes who convert the 2029 Notes in connection with a make-whole fundamental change, as defined in the indenture governing the 2029 Notes, or in connection with a redemption may be entitled to an increase in the conversion rate.

We accounted for the issuance of the 2029 Notes as a single liability measured at its amortized cost, as no other embedded features require bifurcation and recognition as derivatives. The following table is a summary of the 2029 Notes as of September 30, 2025 (in thousands):

​

​ | ​ | ​ | ​
​ |  | September 30,
​ | ​ | 2025

Net carrying amount | ​ | $ | 342,682
​ | ​ | ​ | ​
Fair value (Level 2) | ​ | $ | 505,974

​

The 2029 Notes were not eligible for conversion as of September 30, 2025. No sinking fund is provided for the 2029 Notes, which means that we are not required to redeem or retire them periodically. As of September 30, 2025 we were in compliance with applicable covenants under the indenture governing the 2029 Notes.

Table of Contents

For the three months ended September 30, 2025, total interest expense for the 2029 Notes was $2.4 million (comprised of $2.0 million of contractual interest expense and $0.4 million of amortization of debt discount and issuance costs) compared with total interest expense for the 2029 Notes of $1.9 million (comprised of $1.6 million of contractual interest expense and $0.3 million of amortization of debt discount and issuance costs) for the three months ended September 30 2024. The unamortized debt issuance cost is amortized on the effective interest method over the life of the 2029 Notes.

Other Borrowings

​

Several of our foreign subsidiaries maintain bank lines of credit, denominated in local currencies and U.S. dollars, primarily for the issuance of letters of credit. As of September 30, 2025, $59.9 million was outstanding under these letter-of-credit facilities. As of September 30, 2025, the total amount available under these credit facilities was $35.6 million.

9. Stockholders’ Equity

​

Stock-based Compensation

​

As of September 30, 2025, we maintained the Amended and Restated 2012 Incentive Award Plan (the “OSI Plan”) as a stock-based employee compensation plan.

​

We recorded stock-based compensation expense in the consolidated statements of operations as follows (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended September 30,
​ |  | 2024 |  | 2025
Cost of goods sold | ​ | $ | 244 | ​ | $ | 285
Selling, general and administrative | ​ | ​ | 6,024 | ​ | ​ | 5,753
Research and development | ​ | ​ | 154 | ​ | ​ | 161
Stock-based compensation expense | ​ | $ | 6,422 | ​ | $ | 6,199

​

As of September 30, 2025, total unrecognized compensation cost related to share-based compensation grants under the OSI Plan were estimated at $0.9 million for stock options and $19.9 million for restricted stock units (“RSUs”). We expect to recognize these costs over a weighted average period of 1.8 years with respect to the stock options and 2.2 years with respect to the RSUs.

Nonvested at September 30, 2025 |  | 254,082 | ​ | $ | 145.67

​

As of September 30, 2025, there were approximately 1.6 million shares available for grant under the OSI Plan. Under the terms of the OSI Plan, RSUs granted from the pool of shares available for grant reduce the pool by 1.87 shares for each award granted. RSUs forfeited and returned to the pool of shares available for grant increase the pool by 1.87 shares for each award forfeited.

​

We granted 54,563 and 48,185 performance-based RSUs during the three months ended September 30, 2024 and 2025, respectively. These performance-based RSU awards are contingent on the achievement of certain performance metrics. The payout related to these awards can range from zero to 280% of the original number of shares or units awarded. Compensation cost associated with these performance-based RSUs are recognized based on the estimated number of shares that we ultimately expect will vest. If the estimated number of shares to vest is revised in the future, then stock-based compensation expense will be adjusted accordingly.

​

Stock Repurchase Program

​

In September 2022, our Board of Directors increased the stock repurchase authorization to a total of 2 million shares. This program does not expire unless our Board of Directors acts to terminate the program. The timing and actual numbers of shares to be purchased under this program will depend on a variety of factors, including stock price, general business and market conditions and other investment opportunities. Repurchases may be made from time to time under the program through open-market purchases or privately-negotiated transactions at our discretion. Upon repurchase, the shares are restored to the status of authorized but unissued shares, and we record them in our consolidated financial statements as a reduction in the number of shares of common stock issued and outstanding, with the excess purchase price over par value recorded as a reduction of additional paid-in capital. If additional paid-in capital were to be reduced to zero, we would record the remainder of the excess purchase price over par value as a reduction of retained earnings.

​

During the three months ended September 30, 2025, we did not repurchase any shares of common stock. As of September 30, 2025, there were 1,190,556 shares remaining available for repurchase under the authorized repurchase program.

​

Dividends

​

We have not paid any dividends since the consummation of our initial public offering in 1997 and we do not currently intend to pay any dividends in the foreseeable future. Our Board of Directors will determine the payment of future dividends, if any. Certain of our current bank credit facilities restrict the payment of dividends and future borrowings may contain similar restrictions.

10. Commitments and Contingencies

​

Acquisition-Related Contingent Obligations

​

Under the terms and conditions of the purchase agreements associated with certain acquisitions, we may be obligated to make additional payments based on the achievement of certain sales or profitability milestones through the acquired operations. For agreements that contain contingent consideration obligations, the remaining maximum amount of such potential future payments is $42.8 million as of September 30, 2025.

​

Projections and estimated probabilities are used to estimate future contingent earnout payments, which are discounted back to present value to compute contingent earnout liabilities. The following table provides a roll-forward from June 30, 2025 to September 30, 2025 of the contingent consideration liability, which is included in Other accrued expenses and current liabilities and other long-term liabilities in our consolidated balance sheets (in thousands):

Payments on contingent earnout obligations | ​ |  | (486)
Ending fair value, September 30, 2025 | ​ | $ | 15,845

​

Guarantees

​

We are periodically required to provide performance bonds to do business with certain customers. These arrangements are common in the industry and generally have terms ranging between one year and ten years. The bonds are provided by various bonding agencies. However, we are ultimately liable for claims that may occur against them. As of June 30, 2025 and September 30, 2025, we had a maximum financial exposure related to performance bonds of approximately $104 million and $105 million, respectively. As described in Note 8, we and several of our foreign subsidiaries have issued letters of credit under the revolving credit facility and international bank facilities. These letters of credit are issued to protect various customers, suppliers and government agencies under contractual arrangements and regulatory requirements. We have no history of significant claims and there are no pending matters that would require us to perform under any of these arrangements, and we believe that the resolution of any claims that might arise in the future, either individually or in the aggregate, would not materially affect the consolidated financial statements. Accordingly, no liability for any of these arrangements has been recorded as of June 30, 2025 and September 30, 2025.

​

Environmental Contingencies

​

We are subject to various environmental laws. We conduct environmental investigations at our manufacturing facilities in North America, Asia-Pacific, and Europe, and, to the extent practicable, on all new properties in order to identify, as of the date of such investigation, potential areas of environmental concern related to past and present activities or from nearby operations. In certain cases, we have conducted further environmental assessments consisting of soil and groundwater testing and other investigations deemed appropriate by independent environmental consultants.

​

We have not accrued for loss contingencies relating to environmental matters because we believe that, although unfavorable outcomes are possible, they are not considered by our management to be probable and reasonably estimable. If one or more of these environmental matters are resolved in a manner adverse to us, the impact on our business, financial condition, results of operations and cash flow could be material.

​

Indemnifications

​

In the normal course of business, we have agreed to indemnify certain parties with respect to certain matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations, warranties or covenants, or intellectual property infringement or other claims made by third parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. In addition, we have entered into indemnification agreements with our directors and certain of our officers. It is not possible to determine the maximum potential amount under these indemnification agreements due to, among other factors, the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. We have not recorded any liability for costs related to contingent indemnification obligations as of September 30, 2025.

Product Warranties

​

We offer our customers warranties on many of the products that we sell. These warranties typically provide for repairs and maintenance of the products if problems arise during a specified time period after original shipment. Concurrent with the sale of products, we record a provision for estimated warranty expenses with a corresponding increase in cost of goods sold. We periodically adjust this provision based on historical experience and anticipated expenses. We charge actual expenses of repairs under warranty, including parts and labor, to this provision when incurred. The current obligation for warranty provision is included in other accrued expenses and current liabilities and the noncurrent portion is included in other long-term liabilities in the consolidated balance sheets.

​

The following table presents changes in warranty provisions (in thousands):

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended September 30,
​ |  | 2024 |  | 2025

Reductions for warranty repair costs and adjustments | ​ |  | (719) | ​ | ​ | (1,498)
Balance at end of period | ​ | $ | 11,358 | ​ | $ | 10,564

​

Legal Proceedings

We are involved in potential or actual claims, litigation and other legal proceedings arising in the ordinary course of business. In our opinion after consultation with legal counsel, the ultimate disposition of such proceedings is not likely to have a material adverse effect on our business, financial condition, results of operations or cash flows. We have not accrued for loss contingencies relating to any non-ordinary course matters because we believe that, although unfavorable outcomes in the proceedings are possible, they are not considered by management to be probable and reasonably estimable. If one or more of these matters are resolved in a manner adverse to our Company, the impact on our business, financial condition, results of operations and cash flows could be material.

​

11. Income Taxes

​

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which we operate and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, our tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

​

The effective tax rates for the three months ended September 30, 2024 and 2025 were 21.9% and 19.9%, respectively. During the three months ended September 30, 2024 and 2025, we recognized a net discrete tax benefit of $0.5 million and $0.9 million, respectively, related to equity-based compensation under ASU 2016-09 and changes in prior-year estimates and uncertain tax positions.

​

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was signed into law. Key income-tax related provisions of the OBBBA relevant to our Company include the removal of mandatory capitalization of domestic research and development expenditures, permanent extension of bonus depreciation and revisions to international tax regimes. We are evaluating the financial impact of OBBBA, which is in effect for the current fiscal year ending June 30, 2026. The legislation will affect the timing and recognition of certain deductions, which, if implemented, could impact our effective tax rate and deferred tax balances in future periods.

12. Segment Information

​

We operate in three identifiable industry segments: (a) security and inspection systems (Security division), (b) optoelectronic devices and manufacturing (Optoelectronics and Manufacturing division) and (c) medical monitoring systems (Healthcare division). We also have a corporate segment (Corporate) that includes executive compensation and certain other general and administrative expenses, expenses related to stock issuances and legal, audit and other professional service fees not allocated to industry segments. Both the Security and Healthcare divisions comprise primarily end-product businesses, whereas the Optoelectronics and Manufacturing division primarily supplies components and subsystems to external OEM customers, as well as to the Security and Healthcare divisions. Sales between divisions are at transfer prices that approximate market values. All other accounting policies of the segments are the same as described in Note 1, Basis of Presentation. We disclose segment income (loss) from operations as our measure of segment profit/loss, reconciled to consolidated income (loss) from operations. The measure of segment income (loss) from operations excludes restructuring and other charges presented below which are presented to reconcile to consolidated income from operations. Business segment disclosures consider information used by/provided to our chief operating decision maker (“CODM”). Our Chief Executive Officer serves as the CODM. The CODM uses segment income (loss) from operations, as well as the expenses within each segment including cost of sales, selling, general and administrative expenses and research and development expenses, to allocate resources to segments in the budgeting and forecasting process along with periodic ongoing reviews of results and overall activity in the markets where each segment operates.

The following tables present our results of operations and identifiable assets by our three industry segments, along with amounts for Corporate/Eliminations, which are reconciled to consolidated amounts (in thousands):

Important factors that could cause our actual results to differ materially from our expectations are disclosed in this report, our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 (including Part I, Item 1, “Business,” Part I, Item 1A, “Risk Factors” and Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations”) and other documents filed by us from time to time with the SEC. Such factors, of course, do not include all factors that might affect our business and financial condition. We could be exposed to a variety of negative consequences as a result of delays related to the award of domestic and international contracts; failure to secure the renewal of key customer contracts; delays in customer programs; government shutdown; delays in revenue recognition related to the timing of customer acceptance; the impact of potential information technology, cybersecurity or data security breaches; changes in domestic and foreign government spending, budgetary, procurement, and trade policies adverse to our businesses; the impact of the Russia-Ukraine conflict or conflicts in the Middle East, including the potential for broad economic disruption; global economic uncertainty, including the impact of tariffs; material delays and cancellations of orders or deliveries thereon, supply chain disruptions, plant closures, or other adverse impacts on our ability to execute business plans; unfavorable currency exchange rate fluctuations; unfavorable interest rate fluctuations; effect of changes in tax legislation, guidance and interpretations; market acceptance of our new and existing technologies, products and services; our ability to win new business and convert any orders received to sales within the fiscal year; contract and regulatory compliance matters, and actions, which if brought, could result in judgments, settlements, fines, injunctions, debarment or penalties; and other risks and uncertainties, including but not limited to those factors described in our other SEC filings. All forward-looking statements contained in this report are qualified in their entirety by this section. Moreover, we operate in a very competitive and rapidly changing environment, and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. Investors should not place undue reliance on forward-looking statements as a prediction of actual results. We undertake no obligation other than as may be required under securities laws to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Optoelectronics and Manufacturing Division. Through our Optoelectronics and Manufacturing division, we design, manufacture and market optoelectronic devices and flex circuits and provide electronics manufacturing services globally for use in a broad range of applications, including aerospace and defense electronics, security and inspection systems, medical imaging and diagnostics, telecommunications, office automation, computer peripherals, industrial automation and consumer products. We also provide our optoelectronic devices and electronics manufacturing services to OEM customers and to our own Security and Healthcare divisions. Revenues from external customers in our Optoelectronics and Manufacturing division accounted for 24% and 23% of our total consolidated revenues for the three months ended September 30, 2024 and 2025, respectively.

Healthcare Division. Through our Healthcare division, we design, manufacture, market and service patient monitoring, cardiology and remote monitoring, and connected care systems globally for sale primarily to hospitals and medical centers. Our products monitor patients in critical, emergency and perioperative care areas of the hospital and provide information, through wired and wireless networks, to physicians and nurses who may be at the patient’s bedside, in another area of the hospital or even outside the hospital. Revenues from our Healthcare division accounted for 11% of our total consolidated revenues for each of the three months ended September 30, 2024 and 2025.

Trends and Uncertainties

The following is a discussion of certain trends and uncertainties that we believe have influenced, and may continue to influence, our results of operations.

Global Economic Considerations. Our products and services are sold in numerous countries worldwide, with a large percentage of our sales generated outside the United States. Therefore, we are exposed to and impacted by global macroeconomic factors, U.S. and foreign government policies and foreign exchange fluctuations. There is uncertainty surrounding macroeconomic factors in the U.S. and globally characterized by the supply chain environment, inflationary pressure, rising interest rates, and labor shortages. Increasing diplomatic and trade friction between the U.S. and China has also created significant uncertainty in the global economy. These global macroeconomic factors, coupled with political unrest internationally and the volatile U.S. political climate, have created uncertainty and impacted demand for certain of our products and services. Conflicts in Gaza and nearby regions have created political and economic uncertainty in the Middle East. Also, the continued conflict between Russia and Ukraine and the sanctions imposed in response to this conflict have increased global economic and political uncertainty. While the impact of these factors remains uncertain, we will continue to evaluate the extent to which these factors will impact our business, financial condition or results of operations. We do not know how long this uncertainty will continue. These factors could have a material adverse effect on our business, results of operations and financial condition.

Global Trade. The current domestic and international political environment, including in relation to recent and further potential changes by the U.S. and other countries in policies on global trade and tariffs, have resulted in uncertainty surrounding the future state of the global economy and global trade. This uncertainty is exacerbated by sanctions imposed by the U.S. government against certain businesses and individuals in select other countries. Tariffs and trade restrictions and retaliatory measures by such other countries could result in revenue reductions for the Company or cost increases on material used in our products. We are taking measures to contain costs to reduce the impact of tariffs and to date, such measures have helped reduce our exposure to these conditions. Continued or increased uncertainty regarding global trade due to these or other factors may require us to modify our current business practices and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Healthcare Considerations. Certain hospitals are facing significant financial pressure as supply chain constraints and inflation drive up operating costs and higher interest rates make access to credit more expensive. To the extent macroeconomic conditions remain challenging, it is likely that hospitals’ spend on capital equipment will be adversely impacted.

Government Policies. Our results of operations and cash flows could be materially affected by changes in U.S. or foreign government legislative, regulatory or enforcement policies.

U.S. Federal Government Shutdown. In October 2025, the U.S. federal government entered a partial shutdown due to a lapse in appropriations. As of the date of this filing, the shutdown remains ongoing and has resulted in the suspension or delay of certain government operations and services, including those of certain federal agencies with which we interact. A prolonged shutdown could delay the issuance of government contracts or the processing of existing contracts, particularly in our Security division, issuances of export licenses, shipments, deliveries and payments of invoices. We are actively monitoring the situation and assessing potential impacts on our operations, financial condition, and results of operations. At this time, we are unable to predict the duration of the shutdown or its full impact on our business.

Russia-Ukraine and Israel-Hamas Conflicts. The invasion of Ukraine by Russia and the sanctions imposed in response to this conflict as well as the Israel-Hamas conflict have increased global economic and political uncertainty. This has the potential to indirectly disrupt our supply chain and access to certain resources. While we have not experienced material adverse impacts to date resulting from these conflicts, we have certain research and development activities within Ukraine for our Healthcare division which have been somewhat impacted. The conflicts also have increased the threat of malicious cyber-activity from other countries and other actors.

Currency Exchange Rates. On a year-over-year basis, currency exchange rates positively impacted reported sales by approximately 0.4% for the three months ended September 30, 2025 compared to the three months ended September 30, 2024, primarily due to the weakening of the U.S. dollar against other foreign currencies in 2025. Any strengthening of the U.S. dollar against foreign currencies would adversely impact our sales for the remainder of the fiscal year, and any weakening of the U.S. dollar against foreign currencies would positively impact our sales for the remainder of the fiscal year.

Results of Operations for the Three Months Ended September 30, 2024 (Q1 Fiscal 2025) Compared to the Three Months Ended September 30, 2025 (Q1 Fiscal 2026) (amounts in millions)

Net Revenues

The table below and the discussion that follows are based upon the way in which we analyze our business. See Note 12 to the condensed consolidated financial statements for additional information about our business segments.

​

Revenues for the Security division during Q1 fiscal 2026 increased year-over-year due to increases in product and service revenues of approximately $9.6 million and $20.4 million, respectively. The increase in product revenues was primarily driven by the acquired business further described in Note 2 to the condensed consolidated financial statements. The increase in service revenue was due primarily to an increase in the installed base of products.

Revenues for the Optoelectronics and Manufacturing division during Q1 fiscal 2026 increased year-over-year as a result of an increase in revenues in our contract manufacturing business.

Revenues for the Healthcare division during Q1 fiscal 2026 increased year-over-year primarily due to an increase in patient monitoring and cardiology product sales.

​

Table of Contents

Gross profit is impacted by sales volume and changes in overall manufacturing-related costs, such as raw materials and component costs, warranty expense, provision for inventory, freight, and logistics. Gross profit increased approximately $1.7 million in Q1 fiscal 2026 as compared to the prior year driven by the increase in sales. Gross profit as a percentage of net revenues decreased primarily due to the product revenue mix in our Security division partially offset by an increase in service revenues which typically carry a higher gross margin than product sales.

Operating Expenses

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

Selling, general and administrative. Our significant selling, general and administrative (“SG&A”) expenses include employee compensation, sales commissions, travel, professional services, marketing expenses, foreign currency translation, and depreciation and amortization expense. SG&A expense for Q1 fiscal 2026 was $5.2 million lower than in the same prior-year period primarily due to favorable foreign currency exchange rates offset by an increase in employee compensation and provision for losses on accounts receivable.

Research and development. Research and development (“R&D”) expenses include research related to new product development and product enhancements. R&D expenses increased $2.6 million in Q1 fiscal 2026 as compared to Q1 fiscal 2025 driven by increased compensation costs to support new product development initiatives primarily in our Security and Healthcare divisions.

Restructuring and other charges. Restructuring and other charges generally consist of costs relating to reductions in our workforce, facilities consolidation, costs related to acquisition activity, and other non-recurring charges. During Q1 fiscal 2026, we recognized $2.7 million in restructuring and other charges, which included $2.4 million primarily for other non-recurring charges in the Security and Healthcare divisions and $0.3 million for employee terminations. During Q1 fiscal 2025, we recognized $1.2 million in restructuring and other charges, which included $0.6 million in employee terminations, $0.2 million for facility closure costs for operational efficiency activities, and $0.4 million in acquisition related costs.

Interest and Other Expense, Net

​ |  | Fiscal 2025 |  | Net Revenues |  | Fiscal 2026 |  | Net Revenues
Interest and other expense, net | ​ | $ | 7.4 | ​ | 2.2 | % | ​ | $ | 7.4 | ​ | 1.9 | %

​

Interest and other expense, net. Interest and other expense, net was $7.4 million for each of Q1 fiscal 2026 and 2025. While we generated interest expense savings from lower average levels of borrowings and lower average interest rates in Q1 fiscal 2026 compared to the same prior year period, these savings were offset by a lower benefit from the interest rate swap in Q1 fiscal 2026 compared to the same prior year period.

Income taxes. The effective tax rate for a particular period varies depending on a number of factors, including (i) the mix of income earned in various tax jurisdictions, each of which applies a unique range of income tax rates and income tax credits, (ii) changes in previously established valuation allowances for deferred tax assets (changes are based upon our current analysis of the likelihood that these deferred tax assets will be realized), (iii) the level of non-deductible expenses, (iv) certain tax elections (v) tax holidays granted to certain of our international subsidiaries and (vi) discrete tax items. For Q1 fiscal 2026 and 2025, we recognized a provision for income taxes of $5.1 million and $5.0 million, respectively. The effective tax rates for Q1 fiscal 2026 and 2025 were 19.9% and 21.9%, respectively. During Q1 fiscal 2026 and 2025, we recognized a net discrete tax benefit of $0.9 million and $0.5 million, respectively, related to equity-based compensation under ASU 2016-09.

Liquidity and Capital Resources

​

Our principal sources of liquidity are our cash and cash equivalents, cash generated from operations and our credit facilities. Cash and cash equivalents totaled $124.4 million at September 30, 2025 compared to $106.4 million at June 30, 2025. We currently anticipate that our available funds, credit facilities and cash flow from operations will be sufficient to meet our operational cash needs for the next 12 months and the foreseeable future beyond that. In addition, we anticipate that cash generated from operations, without repatriating earnings from our non-U.S. subsidiaries, and our credit facilities will be sufficient to satisfy our obligations in the U.S.

​

In July 2025 we amended and extended our revolving credit facility to mature in July 2030, to increase the limit from $600 million to $725 million and replaced the $128.1 million term loan with a $100.0 million term loan. The sub-limit for letters of credit was increased from $300 million to $350 million, which includes up to $300 million for borrowings in certain foreign currencies. As of September 30, 2025, there was $98.8 million outstanding under the term loan, $252.1 million outstanding under our revolving credit facility and $95.4 million of outstanding letters of credit. As of September 30, 2025, the total amount available under our revolving credit facility was $377.5 million. See Note 8 to the consolidated financial statements for further discussion.

Cash Provided by (Used in) Operating Activities. Cash flows from operating activities can fluctuate significantly from period to period, as net income, adjusted for non-cash items, and working capital fluctuations impact cash flows. During Q1 fiscal 2026, we generated cash flow from operations of $17.1 million compared to cash used in operations of $37.2 million in the comparable prior-year period. The net change in cash flows from operating activities was due primarily to higher net income in Q1 fiscal 2026 compared to the same period last year, a net decrease in accounts receivable and net increases in accounts payable and advances from customers, partially offset by a net increase in inventories and other changes in net working capital.

Cash Used in Investing Activities. Net cash used in investing activities was $10.9 million for Q1 fiscal 2026 as compared to $87.5 million in the same prior-year period. The decrease in cash used in investing activities was primarily due to the acquisition of a business in Q1 fiscal 2025 compared to none in Q1 fiscal 2026. Capital expenditures in Q1 fiscal 2026 were $7.0 million compared to $7.7 million in the same prior-year period.

Cash Provided by Financing Activities. Net cash provided by financing activities was $12.2 million during Q1 fiscal 2026, compared to $113.8 million during the same prior-year period. The decrease in cash flows from financing activities was primarily due to lower net proceeds from bank borrowings and long-term debt which included proceeds from issuance of the 2029 Notes in the prior year period. There were no repurchases of common shares during Q1 fiscal 2026 compared to repurchases of common shares for an aggregate of $80.4 million in the same prior period. Taxes paid related to net share settlement of equity awards was $34.4 million during Q1 fiscal 2026 compared to $21.3 million in the same prior-year period.

Borrowings

​

See Note 8 to the condensed consolidated financial statements for a detailed discussion regarding our revolving credit facility and other borrowings.

​

Cash Held by Foreign Subsidiaries

​

Our cash and cash equivalents totaled $124.4 million at September 30, 2025. Of this amount, approximately 64% was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in India, United Kingdom, Singapore, and Canada and to a lesser extent Malaysia, Australia, and Indonesia among other countries. We intend to permanently reinvest certain earnings from foreign operations, and we currently do not anticipate that we will need this cash in foreign countries to fund our U.S. operations. In the event we repatriate cash from certain foreign operations and if taxes have not previously been withheld on the related earnings, we would provide for withholding taxes at the time we change our intention with regard to the reinvestment of those earnings.

​

Issuer Purchases of Equity Securities

​

We did not repurchase any shares of common stock during the first quarter of fiscal year 2026.

Contractual Obligations

​

During the first quarter of fiscal year 2026, other than the reduction of our term loan in July 2025, there were no material changes outside the ordinary course of business to the information regarding specified contractual obligations contained in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025. See Notes 1, 6, 8 and 10 to the condensed consolidated financial statements for additional information regarding our contractual obligations.

Recent Accounting Pronouncements

​

From time to time, new accounting pronouncements are issued by the FASB and other regulatory bodies that are adopted as of the specified effective dates. Unless otherwise discussed, management believes that the impact of recently issued standards, which are not yet effective, will not have a material impact on our Consolidated Financial Statements upon adoption. See Note 1 for further discussion. There were no new pronouncements adopted in the first quarter of fiscal year 2026.

​

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

​

For a discussion of our exposure to market risk, refer to our market risk disclosures set forth in Part II, Item 7A “Quantitative and Qualitative Disclosures About Market Risk” in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025. There have been no material changes in our exposure to market risk during the three months ended September 30, 2025 from that described in the Annual Report.

​

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of September 30, 2025, the end of the period covered by this report, our management, including our Chief Executive Officer and our Chief Financial Officer, reviewed and evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) of the Exchange Act). Based upon management’s review and evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the SEC and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the first quarter of fiscal 2026 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud within the Company have been detected.
