AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) ​ 1. Basis of Presentation The 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, 2023 filed with the SEC. The results of operations for the three and six months ended December 31, 2023 are not necessarily indicative of the operating results to be expected for the full 2024 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 these estimates. ​ 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 following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share amounts): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended December 31, Six Months Ended December 31, ​ ​ 2022 2023 2022 2023 Net income available to common stockholders ​ $ 16,354 ​ $ 36,553 ​ $ 27,589 ​ $ 49,432 Weighted average shares outstanding—basic ​ 16,841 ​ ​ 16,995 ​ 16,882 ​ 16,910 Dilutive effect of equity awards ​ 262 ​ ​ 307 ​ 258 ​ 328 Weighted average shares outstanding—diluted ​ 17,103 ​ ​ 17,302 ​ 17,140 ​ 17,238 Basic earnings per share ​ $ 0.97 ​ $ 2.15 ​ $ 1.63 ​ $ 2.92 Diluted earnings per share ​ $ 0.96 ​ $ 2.11 ​ $ 1.61 ​ $ 2.87 Shares excluded from diluted earnings per share due to their anti-dilutive effect ​ ​ 101 ​ ​ 10 ​ ​ 79 ​ ​ 5 ​ 9 Table of Contents 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 $ 127.3 million at December 31, 2023. Of this amount, approximately 92 % was held by our foreign subsidiaries and subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in Mexico, the United Kingdom, India, Malaysia, and Singapore, and to a lesser extent in Puerto Rico, Canada, Egypt, Indonesia, and Australia, 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 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 the 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, 2023 and December 31, 2023. ​ Fair value is the price that would be received to sell 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 measured at quoted prices in active markets for identical assets and liabilities. The “Level 2” category includes assets and liabilities measured from observable inputs other than quoted market prices. The “Level 3” category includes assets and liabilities for which valuation inputs 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, 2023 December 31, 2023 ​ Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets—Insurance company contracts ​ $ — ​ $ 47,181 ​ $ — ​ $ 47,181 ​ $ — ​ $ 51,020 ​ $ — ​ $ 51,020 Assets – Interest rate swap contract ​ $ — ​ $ 5,369 ​ $ — ​ $ 5,369 ​ $ — ​ $ 2,422 ​ $ — ​ $ 2,422 Liabilities—Contingent consideration ​ $ — ​ $ — ​ $ 21,181 ​ $ 21,181 ​ $ — ​ $ — ​ $ 19,656 ​ $ 19,656 ​ Derivative Instruments and Hedging Activity ​ Our use of derivatives consists of foreign currency forward contracts and an interest rate swap agreement. The 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 our consolidated statements of operations. The amounts reported in the consolidated statements of operations for the three and six months ended December 31, 2022 and 2023 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, 2023 and December 31, 2023, we held foreign currency forward contracts with notional amounts totaling $ 21.6 million and $ 84.5 million, respectively. Unrealized gains and losses from our foreign currency forward contracts as of June 30, 2023 and December 31, 2023 were not significant. 10 Table of Contents The 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 over the 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, 2023 and December 31, 2023, 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 contract as of as of June 30, 2023 and December 31, 2023 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 December 31, Six Months Ended December 31, ​ ​ 2022 2023 ​ 2022 2023 Total interest and other expense, net presented in the condensed consolidated statements of operations in which the effects of cash flow hedges are recorded ​ $ ( 5,180 ) ​ $ ( 6,534 ) ​ $ ( 8,612 ) ​ $ ( 12,282 ) Gain (loss) recognized in other comprehensive income (loss), net of tax ​ $ ( 1,012 ) ​ $ ( 3,390 ) ​ $ 2,528 ​ $ ( 2,243 ) Gain reclassified from accumulated other comprehensive income (loss) to interest expense, net ​ $ 164 ​ $ 912 ​ $ 43 ​ $ 1,784 ​ 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. There were no new pronouncements adopted in the second quarter of fiscal year 2024. ​ 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 upon 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, which is up to one year from the acquisition date, as additional information that existed at the acquisition date becomes available for preliminary estimates, 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 2024 Business Acquisition In December 2023, we (through our Optoelectronics and Manufacturing division) acquired a privately held contract manufacturer for approximately $ 6.3 million. The acquisition was financed with cash on hand. The goodwill recognized for this business acquisition is deductible for income tax purposes. In October 2023, we (through our Security division) acquired a privately held provider of radiation detection technology for approximately $ 2.8 million, plus up to $ 3.6 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. 11 Table of Contents Fiscal Year 2023 Business Acquisitions In April 2023, we (through our Optoelectronics and Manufacturing division) acquired a privately held provider of engineering and contract manufacturing solutions for approximately $ 2.5 million, plus up to $ 2.5 million in potential contingent consideration. The acquisition was financed with cash on hand. In February 2023, we (through our Healthcare division) acquired a privately held provider of software and solutions for approximately $ 2.1 million plus up to $ 5.0 million in potential contingent consideration. The acquisition was financed with cash on hand. Through our Security division, we acquired (i) in December 2022 certain assets of a provider of baggage and parcel inspection systems for approximately $ 1.6 million and (ii) in August 2022 a privately held provider of training software and solutions for approximately $ 1.9 million plus an immaterial amount of potential contingent consideration. These acquisitions were financed with cash on hand. The goodwill recognized for each of the fiscal year 2023 business acquisitions is not deductible for income tax purposes. These business acquisitions in fiscal 2023 and 2024, individually and in the aggregate, were not material to our consolidated financial statements. Accordingly, pro-forma historical results of operations and other disclosures related to these businesses have not been presented. ​ 3.

For the six months ended December 31, 2022 and 2023, amortization expense related to intangible assets was $ 9.4 million and $ 10.4 million, respectively. ​ At December 31, 2023, the estimated future amortization expense for intangible assets was as follows (in thousands): ​ Fiscal Year ​ ​ ​ ​ ​ 2024 (remaining 6 months) $ 9,877 2025 ​ 16,378 2026 ​ 12,751 2027 ​ 8,832 2028 ​ ​ 5,829 Thereafter ​ 58,149 Total ​ $ 111,816 ​ 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 compared 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 months ended December 31, 2022 and 2023, we capitalized software development costs in the amounts of $ 4.0 million. For the six months ended December 31, 2022 and 2023, we capitalized software development costs in the amounts of $ 7.9 million and $ 8.0 million, respectively. 13 Table of Contents 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, 2023 and December 31, 2023, including the change between the periods. There were no substantial non-current contract assets for the periods presented. Contract Assets (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ ​ ​ 2023 2023 Change % Change Unbilled revenue (included in accounts receivable, net) ​ $ 86,818 ​ $ 155,543 ​ $ 68,725 ​ 79 % Contract Liabilities (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, December 31, ​ ​ ​ 2023 2023 Change % Change ​ Advances from customers ​ $ 21,250 ​ $ 40,263 ​ $ 19,013 ​ 89 % Deferred revenue—current ​ 43,861 ​ ​ 37,661 ​ ​ ( 6,200 ) ​ ( 14 ) % Deferred revenue—long-term ​ 22,200 ​ ​ 20,109 ​ ​ ( 2,091 ) ​ ( 9 ) % ​ Contract assets increased during the three months ended December 31, 2023 primarily from the timing and nature of milestones met in contracts for a number of customers in our Security division where we met the revenue recognition criteria under ASC 606 in advance of the time when contracts give us the right to invoice customers. The net increase in contract liabilities was primarily due to activity in our Security division for deposits received on contracts, partially offset by recognition of revenue on service contracts included in deferred revenue. ​ 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 December 31, 2023, the portion of the transaction price allocated to remaining performance obligations was approximately $ 928.2 million. We expect to recognize revenue on approximately 66 % of the remaining performance obligations over the next 12 months , and the remainder is expected to be recognized thereafter. During the six months ended December 31, 2023, we recognized revenue of $ 44.3 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 a separate performance obligation. 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. ​ 14 Table of Contents 6.

Restructuring and Other Charges ​ We endeavor to align our global capacity and infrastructure with demand by our customers as well as fully integrate acquisitions and thereby improve operational efficiency. ​ During the three months ended December 31, 2023, we recognized $ 1.0 million in restructuring and other charges, which included $ 0.2 million in acquisition related costs, $ 0.3 million in legal charges, $ 0.3 million for facility closure costs for operational efficiency activities, and $ 0.2 million for employee terminations. During the six months ended December 31, 2023, we recognized $ 1.5 million in restructuring and other charges, which included $ 0.4 million in acquisition related costs, $ 0.4 million in legal charges, $ 0.3 million for facility closure costs for operational efficiency activities, and $ 0.3 million for employee terminations. ​ 15 Table of Contents During the three months ended December 31, 2022, we recognized $ 2.3 million in restructuring and other charges, which included $ 1.9 million in legal charges primarily related to government investigations and $ 0.2 million for employee terminations.

Borrowings ​ Revolving Credit Facility ​ Our senior secured credit facility comprises a term loan and a $ 600 million revolving credit facility which matures in December 2026. The revolving credit facility includes a $ 300 million sub-limit for letters of credit. Under certain circumstances and subject to certain conditions, we have the ability to increase the revolving credit facility by the greater of $ 250 million or such amount as would not cause our secured leverage ratio to exceed a specified level. Borrowings under the facility bear interest at SOFR plus a margin of 1.0 % as of December 31, 2023 (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 bears a commitment fee of 0.10 % as of December 31, 2023 (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 December 31, 2023, there were $ 316.0 million of borrowings outstanding under the revolving credit facility, $ 54.0 million outstanding under the letters of credit sub-facility, and $ 139.4 million outstanding under the term loan. As of December 31, 2023, the amount available to borrow under the revolving credit facility was $ 230.0 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 December 31, 2023, we were in compliance with all financial covenants under this credit facility. In September 2022, we entered into an interest rate swap 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 details. Interest expense related to the credit facility and term loan was $ 5.0 million and $ 7.0 million for the three months ended December 31, 2022 and 2023, respectively, and $ 7.1 million and $ 13.3 million for the six months ended December 31, 2022 and 2023, respectively. 1.25% Convertible Senior Notes (“Notes”) Due 2022 ​ In February 2017, we issued $ 287.5 million of the Notes in a private offering. On September 1, 2022, we repurchased and cancelled the then - remaining $ 242.3 million balance of the Notes. Total interest expense recognized for the three and six months ended December 31, 2022 related to the Notes was nil and $ 0.7 million, respectively, which consisted of $ 0.5 million of contractual interest expense and $ 0.2 million of amortization of debt issuance costs. 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 December 31, 2023, $ 57.5 million was outstanding under these letter-of-credit facilities. As of December 31, 2023, the total amount available under these credit facilities was $ 19.0 million. ​ 17 Table of Contents Long-term debt consisted of the following (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2023 2023 Term loan ​ $ 143,125 ​ $ 139,375 Other long-term debt ​ 1,442 ​ ​ 1,537 ​ ​ 144,567 ​ ​ 140,912 Less current portion of long-term debt ​ ( 8,076 ) ​ ​ ( 8,120 ) Long-term portion of debt ​ $ 136,491 ​ $ 132,792 ​ ​ 9. Stockholders’ Equity ​ Stock-based Compensation ​ As of December 31, 2023, 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 December 31, Six Months Ended December 31, ​ 2022 2023 ​ 2022 2023 Cost of goods sold ​ $ 241 ​ $ 255 ​ $ 457 ​ $ 487 Selling, general and administrative ​ ​ 6,870 ​ ​ 6,945 ​ 13,710 ​ 13,676 Research and development ​ ​ 128 ​ ​ 128 ​ 249 ​ 254 Stock-based compensation expense ​ $ 7,239 ​ $ 7,328 ​ $ 14,416 ​ $ 14,417 ​ As of December 31, 2023, total unrecognized compensation cost related to share-based compensation grants under the OSI Plan were estimated at $ 1.2 million for stock options and $ 23.8 million for restricted stock units (“RSUs”). We expect to recognize these costs over a weighted average period of 2.4 years with respect to the stock options and 2.3 years with respect to the RSUs. ​ The following summarizes stock option activity during the six months ended December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ Average ​ Weighted-Average ​ Aggregate ​ ​ Number of ​ Exercise ​ Remaining Contractual ​ Intrinsic Value ​ Options Price Term (in thousands) Outstanding at June 30, 2023 83,677 $ 87.09 ​ ​ ​ ​ Granted 22,438 ​ ​ 119.45 ​ ​ ​ ​ ​ Exercised ( 14,489 ) ​ ​ 81.93 ​ ​ ​ ​ ​ Expired or forfeited ( 4,375 ) ​ $ 86.09 ​ ​ ​ ​ ​ Outstanding at December 31, 2023 87,251 ​ $ 96.32 ​ 7.7 years ​ $ 2,856 Exercisable at December 31, 2023 ​ 42,856 ​ ​ ​ 6.1 years ​ $ 1,797 ​ The following summarizes RSU award activity during the six months ended December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted- ​ ​ ​ ​ Average ​ Shares Fair Value Nonvested at June 30, 2023 455,515 ​ $ 85.15 Granted 331,278 ​ ​ 95.23 Vested ( 384,614 ) ​ ​ 79.51 Forfeited ( 5,226 ) ​ ​ 84.66 Nonvested at December 31, 2023 396,953 ​ $ 99.03 ​ In December 2023, our shareholders approved an amendment to the OSI Plan, which increased the shares available under the OSI Plan by 2.4 million shares. As of December 31, 2023, there were approximately 2.5 million shares available for grant under the OSI Plan. 18 Table of Contents Under the terms of the OSI Plan, RSUs and restricted stock granted from the pool of shares available for grant reduce the pool by 1.87 shares for each award granted. RSUs and restricted stock forfeited and returned to the pool of shares available for grant increase the pool by 1.87 shares for each award forfeited. ​ We granted 110,811 and 75,988 performance-based RSUs during the six months ended December 31, 2022 and 2023, 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 376 % 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 purchased 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 is reduced to zero, we record the remainder of the excess purchase price over par value as a reduction of retained earnings. ​ During the six months ended December 31, 2023, we did not repurchase shares of our common stock. As of December 31, 2023, there were 1,721,870 shares remaining available for repurchase under the authorized repurchase program. ​ Dividends ​ We have not paid any cash dividends since the consummation of our initial public offering in 1997 and we do not currently intend to pay any cash dividends in the foreseeable future. Our Board of Directors will determine the payment of future cash dividends, if any. Certain of our current bank credit facilities restrict the payment of cash 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 that are capped, the remaining maximum amount of such potential future payments is $ 48.7 million as of December 31, 2023. ​ 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, 2023 to December 31, 2023 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): ​ ​ ​ ​ ​ Beginning fair value, June 30, 2023 $ 21,181 Addition of contingent earnout obligations ​ ​ 1,766 Foreign currency translation adjustment ​ ​ 62 Changes in fair value for contingent earnout obligations ​ ( 2,889 ) Payments on contingent earnout obligations ​ ( 464 ) Ending fair value, December 31, 2023 ​ $ 19,656 ​ 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 19 Table of Contents 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 and Certain Employment-Related Contingencies ​ 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 breaches 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 liability amount under these indemnification agreements due to 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 December 31, 2023. ​ On December 31, 2017, we and Deepak Chopra, our Chief Executive Officer, entered into an amendment to Mr. Chopra’s employment agreement that, among other things, provides for a $ 13.5 million bonus payment to Mr. Chopra on or within 45 days of January 1, 2024 contingent upon Mr. Chopra’s continued employment with us through that date, subject to accelerated payout terms in the event of Mr. Chopra’s death or disability. The accrued bonus of $ 13.5 million is included in accrued payroll and related expenses and is payable during the three-month period ending March 31, 2024. ​ 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): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended December 31, ​ 2022 2023 Balance at beginning of period ​ $ 13,347 ​ $ 11,149 Additions ​ ​ 1,705 ​ ​ 1,417 Reductions for warranty repair costs and adjustments ​ ( 4,318 ) ​ ​ ( 2,070 ) Balance at end of period ​ $ 10,734 ​ $ 10,496 ​ Legal Proceedings In February 2023, one of our subsidiaries received a subpoena from the U.S. Department of Justice (“DoJ”). The subpoena was issued as part of a DoJ case against a former employee of an OSI Systems subsidiary for embezzlement and other conduct occurring before he was hired by our subsidiary and while he was employed by another company in the United States and Mexico. The subpoena requests documents and records relating to, among other things, the former employee and the Company’s business dealings in Mexico since 2020. We have produced documents in response to this subpoena and intend to cooperate with any further subpoenas or other requests in connection with this or any ensuing investigation. We are involved in various other potential or actual claims and 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- 20 Table of Contents 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 December 31, 2022 and 2023 were 19.5 % and 20.2 %, respectively. During the three months ended December 31, 2022, we recognized a net discrete tax benefit of $ 0.4 million related to equity-based compensation under ASU 2016-09 and a benefit of $ 0.4 million for changes in prior year tax estimates. During the three months ended December 31, 2023, we recognized a net discrete tax benefit of $ 0.2 million related to equity-based compensation under ASU 2016-09 and a benefit of $ 2.3 million from changes in prior year tax estimates. ​ The effective tax rates for the six months ended December 31, 2022 and 2023 were 21.6 % and 21.0 %, respectively. During the six months ended December 31, 2022, we recognized net discrete tax benefit of $ 0.5 million related to equity-based compensation under ASU 2016-09 and a benefit of $ 0.4 million from changes in prior year tax estimates. During the six months ended December 31, 2023, we recognized a net discrete tax benefit of $ 0.6 million related to equity-based compensation under ASU 2016-09 and a benefit of $ 2.3 million from changes in prior year tax estimates. ​ 12. Segment Information ​ We have determined that 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. 21 Table of Contents The following tables present our results of operations and identifiable assets by industry segment (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ December 31, ​ December 31, ​ 2022 2023 2022 2023 Revenues (1) —by Segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Security division ​ $ 167,444 ​ $ 249,975 ​ $ 312,436 ​ $ 414,604 Optoelectronics and Manufacturing division, including intersegment revenues ​ ​ 98,709 ​ ​ 98,097 ​ ​ 192,625 ​ ​ 194,225 Healthcare division ​ ​ 43,520 ​ ​ 41,850 ​ ​ 87,083 ​ ​ 79,637 Intersegment revenues elimination ​ ​ ( 14,076 ) ​ ​ ( 16,687 ) ​ ​ ( 28,476 ) ​ ​ ( 36,021 ) Total ​ $ 295,597 ​ $ 373,235 ​ $ 563,668 ​ $ 652,445 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Income (loss) from operations —by Segment: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Security division ​ $ 21,593 ​ $ 51,856 ​ $ 36,518 ​ $ 72,465 Optoelectronics and Manufacturing division ​ ​ 12,212 ​ ​ 11,621 ​ ​ 23,470 ​ ​ 23,058 Healthcare division ​ ​ 1,404 ​ ​ 429 ​ ​ 3,032 ​ ​ 593 Corporate ​ ​ ( 9,276 ) ​ ​ ( 11,183 ) ​ ​ ( 19,424 ) ​ ​ ( 21,099 ) Intersegment eliminations ​ ​ ( 442 ) ​ ​ ( 402 ) ​ ​ 195 ​ ​ ( 137 ) Total ​ $ 25,491 ​ $ 52,321 ​ $ 43,791 ​ $ 74,880 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2023 2023 Assets (2) —by Segment: ​ ​ ​ ​ ​ ​ Security division ​ $ 948,126 ​ $ 1,118,783 Optoelectronics and Manufacturing division ​ 310,930 ​ ​ 243,887 Healthcare division ​ ​ 245,856 ​ ​ 302,479 Corporate ​ 94,678 ​ ​ 108,321 Eliminations (3) ​ ( 43,904 ) ​ ​ ( 46,993 ) Total ​ $ 1,555,686 ​ $ 1,726,477 (1) For the three and six month periods ended December 31, 2022, no customer accounted for greater than 10 % of total net revenues.
