OSI SYSTEMS INC

1.SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Description of Business—OSI Systems, Inc., together with our subsidiaries, is a vertically integrated designer and manufacturer of specialized electronic systems and components for critical applications. We sell our products and provide related services in diversified markets, including homeland security, healthcare, defense and aerospace.

We have three reporting segments: (i) Security, providing security and inspection systems, radio frequency solutions and turnkey security screening solutions; (ii) Optoelectronics and Manufacturing, providing specialized electronic components and electronic manufacturing services for applications in the defense and aerospace markets, among others, and for our Security and Healthcare divisions and (iii) Healthcare, providing patient monitoring, cardiology and remote monitoring, and connected care systems and associated accessories.

Through our Security segment, we provide security screening products and related services globally. These products and services are used to inspect baggage, parcels, cargo, people, vehicles and other objects for weapons, explosives, drugs, radioactive and nuclear materials and other contraband, as well as radio frequency transmission equipment, such as high-power transmitters, amplifiers and power supplies for broadcast, communications, science and industry. In addition to these products, we also provide site design, installation, training and technical support services to our customers. We also provide turnkey security screening solutions, which can include the construction, staffing and long-term operation of security screening checkpoints for our customers.

Through our Optoelectronics and Manufacturing segment, 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. This division provides products and services to OEM customers and to our own Security and Healthcare divisions.

Through our Healthcare segment, we design, manufacture, market and service patient monitoring, cardiology and remote monitoring, and connected care systems and associated accessories globally. These products are used by care providers in critical care, emergency and perioperative areas within 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.

Consolidation—The consolidated financial statements include the accounts of OSI Systems, Inc. and our wholly-owned and majority-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Investments in joint ventures over which we have significant influence but do not have voting control are accounted for using the equity method. Investments over which we do not have significant influence or control are not material and are carried at cost as there isno readily determinable fair value for equity interests.

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.

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.

Accounts Receivable—We monitor collections and payments from our customers, and we maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. We determine the allowance based on known troubled accounts, historical experience, current economic trends that might impact the level of credit losses in the future and other available information. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances could be required.

Inventories— The majority of our inventories are valued using the average costing method with select subsidiaries using the standard costing method. All methods of valuing inventory used by the Company approximate the first-in, first-out basis for valuing inventory. Inventories are generally stated at the lower of cost (first-in, first-out) or net realizable value. We write down inventory for slow-moving and obsolete inventory based on historical usage, orders on hand, assessments of future demands, market conditions among other items. If these factors become less favorable than those projected, additional inventory write-downs may be required.

Property and Equipment—Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are charged while assets are used in service and are computed using the straight-line method over the estimated useful lives of the assets taking into consideration any estimated salvage value. Amortization of leasehold improvements is calculated on the straight-line method over the shorter of the useful life of the asset or the lease term. Right-of-use assets from finance leases are included in property and equipment. Amortization of property and equipment under finance leases is included with depreciation expense. In the event that property and equipment are idle, as a result of excess capacity or the early termination, non-renewal or reduction in scope of a turnkey screening operation, such assets are assessed for impairment on a periodic basis or if any indicators of impairment exist.

Goodwill and Other Intangible Assets and Valuation of Long-Lived Assets—Goodwill represents the excess purchase price over the estimated fair value of the assets acquired and liabilities assumed in a business combination. Goodwill is allocated to our reporting units based on the nature of the product line of the acquired business. The carrying value of goodwill and indefinite life intangible assets are not amortized but are annually tested for impairment as of the end of the second quarter and more frequently if there is an indicator of impairment. We assess qualitative factors of each of ourthree reporting units to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill and intangible assets. The assessments conducted as of December 31, 2025 indicated that it is not more likely than not that the fair values of ourthree reporting units are less than their carrying amounts, including goodwill and intangible assets. There were no qualitative factors which would trigger impairment testing of goodwill and indefinite life intangible assets between measurement dates. Thus, we have determined that there isno goodwill or indefinite life intangible assets impairment for any of thethree reporting units.

We evaluate long-lived assets with finite lives for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Impairment is considered to exist if the total estimated future cash flows on an undiscounted basis are less than the carrying amount of the assets. If impairment does exist, we measure the impairment loss and record it based on the discounted estimate of future cash flows. In estimating future cash flows, we group assets at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows from other asset groups. Our estimate of future cash flows is based upon, among other things, certain assumptions about expected future operating performance, growth rates and other factors.

Income Taxes—Deferred income taxes are provided for temporary differences between the financial statement and income tax basis of our assets and liabilities, based on enacted tax rates. A valuation allowance is provided when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Income tax accounting standards prescribe a two-step process for the financial statement measurement and recognition of a tax position taken or expected to be taken in a tax return. The first step involves determination of whether it is more likely than not (greater than 50 percent likelihood) that a tax position will be sustained upon examination, based on the technical merits of the position. The second step requires that any tax position that meets the more likely than not recognition threshold be measured and recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. See Note 10 for additional information.

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 term loan and lease obligations 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, 2026.

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 comprises assets and liabilities measured at quoted prices in active markets for identical assets and liabilities. The “Level 2” category comprises assets and liabilities measured from observable inputs other than quoted market prices. The “Level 3” category comprises 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 11 to the consolidated financial statements, are in the “Level 3” category for valuation purposes.

The fair values of our financial assets and liabilities as of June 30, 2025 and 2026 are categorized as follows (in thousands):

Derivative Instruments and Hedging Activity— Our use of derivatives consists of foreign currency forward contracts, a cross-currency interest rate swap contract 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 use a cross-currency interest rate swap contract to hedge our net investment in a foreign subsidiary. 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 years ending June 30, 2024, 2025 and 2026 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 2026, we held foreign currency forward contracts with notional amounts totaling $99.9 million and $138.0 million, respectively. Unrealized gains and losses from our foreign currency forward contracts as of June 30, 2025 and 2026 were not significant.

We entered into a cross-currency interest rate swap contract in June 2026, which matures in June 2027. The net gains or losses from our cross-currency interest rate swap contract, which is designated as a net investment hedge instrument in a foreign subsidiary, are reported in accumulated other comprehensive loss in the consolidated statements of stockholders’ equity, and the amounts reported for the fiscal year ended June 30, 2026 was not significant. The fair value of our cross-currency interest rate swap contract 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, 2026, the notional amount of this contract was $35.0 million. The unrealized gain from our cross-currency interest rate swap contract as of June 30, 2026 was not significant. The net interest rate benefit from this contract recognized in interest and other expense, net was not significant for the fiscal year ended June 30, 2026.

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 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 June 30, 2026, the notional amount of the interest rate swap hedge derivative instrument was $175 million. The fair value of the interest rate swap contract as of June 30, 2025 and June 30, 2026 is recorded in Other assets within the consolidated balance sheet.

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

Revenue Recognition

We recognize revenue under Accounting Standards* *Codification Topic 606, Revenue from Contracts with Customers (“ASC 606”), which superseded all prior revenue recognition methods and industry-specific guidance. The core principle of ASC 606 is that an entity should recognize revenue to depict the transfer of control for promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the revenue recognition principles, an entity is required to identify the contract(s) with a customer, identify the performance obligations, determine the transaction price, allocate the transaction price to the performance obligations and recognize revenue as the performance obligations are satisfied (i.e., either over time or at a point in time). ASC 606 further requires that companies disclose sufficient information to enable readers of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Product Sales. We recognize revenue from sales of products upon shipment or delivery when control of the product transfers to the customer, depending on the terms of each sale, and when collection is probable. We generally offer customers payment terms of less than one year. In cases when payment terms extend beyond one year, we consider whether the contract has a significant financing component. In the circumstance where terms of a product sale include subjective customer acceptance criteria, revenue is deferred until we have achieved the customer acceptance criteria unless such acceptance criteria are perfunctory or inconsequential. On occasion, customers request that completed products be held for future delivery for the customers’ convenience under bill-and-hold arrangements due to site readiness, installation scheduling, importation, or other customer-specific considerations. Determining whether control transfers before physical possession in these bill-and-hold arrangements requires significant judgment. We recognize revenue only when the bill-and-hold criteria in ASC 606 are met, including that the products are separately identified, ready for shipment, and cannot be redirected to another customer. Any storage provided after control transfers is not a separate performance obligation. We recognized bill-and-hold revenues of $64.7 million, $19.1 million and $5.5 million for the fiscal years ended June 30, 2026, 2025 and 2024 respectively. The increase in fiscal year 2026 compared to fiscal year 2025 was primarily attributable to customer-requested shipment delays from site readiness and delivery constraints on certain contracts in the Security division for infrastructure and border security projects. The increase in fiscal year 2025 compared to fiscal year 2024 was primarily due to customer-requested shipment delays from site readiness and delivery constraints on certain contracts in the Security division for border security projects.

Service Revenue. Revenue from services includes installation and implementation of products and turnkey security screening services and after-market services. Generally, revenue from services is recognized over time as the services are performed. Revenues from out of warranty service maintenance contracts are recognized ratably over the respective terms of such contracts. Deferred revenue for such services arises from payments received from customers for services not yet performed.

Contract Revenue. Sales agreements with customers can be project specific, cover a period of time, and can be renewable periodically. The contracts may contain terms and conditions with respect to payment, delivery, installation, services, warranty and other rights. In certain instances, we consider an accepted customer order, governed by a master sales agreement, to be the contract with the customer when legal rights and obligations exist. Contracts with customers may include the sale of products and services, as discussed in the paragraphs above. In certain instances, contracts can contain multiple performance obligations as discussed in the paragraph below. According to the terms of a sale contract, we may receive consideration from a customer prior to transferring goods to the customer, and we record these prepayments as an advance receipt. We also record deferred revenue, typically related to service contracts, when consideration is received before the services have been performed. We recognize contract liabilities and deferred revenue as net sales after all revenue recognition criteria are met.

When determining revenue recognition for contracts, we make judgments based on our understanding of the obligations in each contract. We determine whether or not customer acceptance criteria are perfunctory or inconsequential. The determination of whether or not customer acceptance terms are perfunctory or inconsequential impacts the amount and timing of revenue recognition. Judgments also include estimates of warranty reserves, which are established based on historical experience and knowledge of the product under warranty.

Multiple Performance Obligations. Certain agreements with customers include the sale of capital equipment involving multiple elements that may include civil works to prepare a site for the installation of equipment, manufacture and delivery of equipment, installation and integration of equipment, training of customer personnel to operate the equipment and after-market service of the equipment. We assign multiple elements in a contract into separate performance obligations if those elements are distinct, both individually and in the context of the contract. If multiple promises comprise a series of distinct services which are substantially the same and have the same pattern of transfer, they are combined and accounted for as a single performance obligation.

In cases where obligations in a contract are distinct and thus require separation into multiple performance obligations, revenue recognition guidance requires that contract consideration be allocated to each distinct performance obligation based on its relative standalone selling price. The value allocated to each performance obligation is then recognized as revenue when the revenue recognition criteria for each distinct obligation or bundle of obligations has been met.

The standalone selling price for each performance obligation is an amount that depicts the amount of consideration to which the entity expects to be entitled in exchange for transferring the good or service. When there is only one performance obligation associated with a contract, the entire sale value is attributed to that obligation. When a contract contains multiple performance obligations, the standalone selling price is first estimated using the observable price, which is generally a list price net of applicable discount, or the price used to sell the good or service in similar circumstances. In circumstances when a selling price is not directly observable, we will estimate the standalone selling price using information available to us including our market assessment and/or expected cost plus margin.

The timetable for fulfilment of each of the distinct performance obligations can range from completion in a short amount of time and entirely within a single reporting period to completion over several reporting periods. The timing of revenue recognition for each performance obligation may be dependent upon several milestones, including physical delivery of equipment, completion of factory acceptance test, completion of site acceptance test, installation and connectivity of equipment, certification of training of personnel and, in the case of after-market service deliverables, the passage of time (typically evenly over the post-warranty period of the service deliverable).

We often provide a guarantee to support our performance under multiple performance obligations. In the event that customers are permitted to terminate such arrangements, the underlying contract typically requires payment for deliverables and reimbursement of costs incurred through the date of termination.

We disaggregate revenue by reporting segment (Security, Optoelectronics and Manufacturing, and Healthcare) to depict the nature of revenue in a manner consistent with our business operations and to be consistent with other communications and public filings. Refer to Note 14 for additional details of revenues by reporting segment.

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 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 sheet. We may also receive consideration, per the terms of a contract, from customers prior to transferring 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. We recognize these contract liabilities as sales after all revenue recognition criteria are met.

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 afinancing component if the period of time between transfer of goods and services and customer payment is greater than one year.

Freight—We record shipping and handling fees that we charge to our customers as revenue and related costs as cost of goods sold.

Research and Development Costs—Research and development costs are those costs related to the development of a new product, process or service, or significant improvement to an existing product, process or service. Such costs are charged to operations as incurred.

Stock-Based Compensation—Stock-based compensation cost is measured at the grant date based on the estimated fair value of the award and is recognized as expense over the employee’s requisite service period for all stock-based awards granted or modified. Certain restricted stock unit awards vest based on the achievement of pre-established performance criteria. The fair value of performance-based awards is estimated at the date of grant based upon the probability that the specified performance criteria will be met, adjusted for estimated forfeitures. Each quarter we update our assessment of the probability that the specified performance criteria will be achieved and adjust the estimate of the expenses of the performance-based awards if necessary. We amortize the fair value of performance-based awards over the requisite service period for each separately vesting tranche of the award. See Note 9 to the consolidated financial statements.

Impairment, Restructuring and Other Charges—We account for certain charges related to restructuring activities, litigation, acquisition-related costs and other non-routine charges as Impairment, restructuring and other charges in the consolidated financial statements. See Note 7 for additional information about these charges.

Credit Risk and Concentration— Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities and accounts receivable. We restrict investments in cash equivalents to financial institutions with high credit standing. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of our company’s worldwide customer base. As of June 30, 2025, one customer in the Security division accounted for 42% of accounts receivable, net. As of June 30, 2026, one customer in the Security division accounted for 25% of accounts receivable, net. In fiscal year 2025, one Security division customer accounted for 11% of net revenues. In fiscal year 2026, no customer accounted for greater than 10% of net revenues. We perform ongoing credit evaluations of our customers’ financial condition and maintain allowances for potential credit losses.

Our cash and cash equivalents totaled $106.4 million and $359.8 million at June 30, 2025 and 2026, respectively. Of these amounts, approximately 78% and 23% were held by our foreign subsidiaries at June 30, 2025 and 2026, respectively, and are subject to repatriation tax considerations. These foreign funds were held primarily by our subsidiaries in India, United Kingdom, Singapore, Canada, and Malaysia. 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.

For cost, quality control, technological, and efficiency reasons, we purchase certain materials, parts, and components only from single vendors with whom we have ongoing relationships. We do, however, qualify second sources for many of our materials, parts, and components. While management believes that relying on key vendors improves the efficiency and reliability of business operations, relying on any one vendor for a significant aspect of business can have a significant negative impact on revenue and profitability if that vendor fails to perform at acceptable service levels for any reason, including financial difficulties of the vendor.

Foreign Currency Translation and Transactions— We transact business in various foreign currencies. In countries where the functional currency of the underlying operations has been determined to be the local country’s currency, revenues and expenses of operations outside the United States are translated into United States dollars using average exchange rates while assets and liabilities of operations outside the United States are translated into United States dollars using period-end exchange rates. The effects of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets. We also have subsidiaries where the United States dollar has been designated as the functional currency based on individual facts and circumstances. Remeasurement of non-United States dollar monetary assets and liabilities are translated using period-end exchange rates and associated gains and losses are recognized in the consolidated statements of operations. Non-monetary assets and liabilities are translated using historical exchange rates. Foreign currency losses which were included in our consolidated statement of operations, amounted to approximately$5.1 million,$12.7 million and$1.6 million for the fiscal years ended June 30, 2024, 2025 and 2026, respectively.

Business Combinations—Under ASC 805, the acquisition method of accounting requires us to record assets acquired and 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 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 until we have all the necessary information about the facts and circumstances that existed as of the acquisition date 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 provisional amounts initially recorded for assets acquired and liabilities assumed. Upon the conclusion of the measurement period, any subsequent adjustments are included in earnings.

Earnings per Share—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”) and the 0.50% convertible senior notes due 2031 (the “2031 Notes”) 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 for the 2029 Notes and $353.82 for the 2031 Notes because the principal amounts of the respective convertible senior 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 fiscal year ended June 30, 2026. There was no dilutive impact of the 2031 Notes.

The following table sets forth the computation of basic and diluted earnings per share (in thousands, except per share amounts):

Warranty Provision—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, whose activity for each of the three fiscal years ended June 30, 2026 is summarized in the following table (in thousands):

Leases—Right-of-use (“ROU”) assets represent our right to use an underlying asset during the reasonably certain lease terms, and lease liabilities represent our obligation to make lease payments arising from the leases. We recognize ROU lease assets and lease liabilities at lease commencement on our consolidated balance sheet based on the present value of lease payments over the lease term using a discount rate determined based on our incremental borrowing rate since the rate implicit in each lease is not readily determinable. We elected the package of practical expedients, which permits us to not reassess (1) whether any expired or existing contracts are or contain leases, (2) the lease classification of any expired or existing leases, and (3) any initial direct costs for any existing leases as of the effective date. We elected the practical expedient to account for each separate lease component of a contract and its associated non-lease components as a single lease component. We also elected the hindsight practical expedient, which allows us to use hindsight in determining the lease term. We do not record a ROU asset and corresponding lease liability for leases with an initial term of one year or less (“short-term leases”). The terms in our leases may include options to extend or terminate the lease. We recognize ROU assets and liabilities when it is reasonably certain that we will exercise those options. Judgment is required in our assessment as to whether renewal or termination options are reasonably certain to be exercised and factors such as contractual terms compared to current market rates and the importance of the facility and location to our operations, among others, are considered. Lease payments are made in accordance with the lease terms, and lease expense, including short-term lease expense, is recognized on a straight-line basis over the lease term.

We lease facilities and certain equipment under various operating lease agreements. The majority of our lease arrangements are comprised of fixed payments while certain of our other leases provide for periodic rent increases. Our leases may contain escalation clauses and renewal options. Most of the leases require us to pay for certain other costs such as common area maintenance and property taxes. Rent expense for leases with periodic rent increases or escalation clauses is recognized on a straight-line basis over the minimum lease term. The lease agreements do not contain any material residual value guarantees or material restrictive covenants. We also have finance leases for fleet vehicles that are not material to the consolidated financial statements.

Subsequent Event—In accordance with ASC 855, our management evaluated material events after the balance sheet date through the date of the filing of this report with the SEC. Other than the increase in the stock repurchase authorization described in Note 9, no subsequent events occurred that required adjustment to, or disclosure in, the consolidated financial statements.

Recent Accounting Guidance

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 below, management believes that the impact of recently issued standards, which are not yet effective for the Company, will not have a material impact on our Consolidated Financial Statements upon adoption.

Accounting Guidance 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 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 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. We adopted ASU 2023-09 in fiscal year 2026 on a prospective basis.

Accounting Guidance Not Yet Adopted

In November 2024, the FASB issued Accounting Standards Update 2024-03, “Income Statement-Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures”, (“ASU 2024-03”) which requires additional 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. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted and may be applied either on a prospective or retrospective basis. We are evaluating the potential impact of ASU 2024-03 on disclosures in our Consolidated Financial Statements which will be effective beginning with our Form 10-K for fiscal year 2028.

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 standard is effective for annual reporting periods beginning after December 15, 2027, including interim periods within those annual periods. Early adoption is permitted. The amendments are to be applied retrospectively, prospectively, or a modified transition approach may be used based on the status of the project and whether software costs were capitalized before the date of adoption. We are evaluating the potential impact of ASU 2025-06 on disclosures in our Consolidated Financial Statements which will be effective beginning with our Form 10-K for fiscal year 2029.

In December 2025, the FASB issued Accounting Standards Update 2025-11, “Interim Reporting (Topic 270): Narrow-Scope Improvements” (ASU 2025-11”), which clarifies the application, form and content, and required disclosures for interim financial statements prepared in accordance with GAAP. The ASU improves the organization and clarity of ASU 2025-11 by specifying interim reporting requirements, consolidating required interim disclosures and introducing a disclosure principle for events and changes occurring after the end of the most recent annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. We are evaluating the potential impact of ASU 2025-11 on disclosures in our Consolidated Financial Statements which will be effective for interim periods beginning fiscal year 2029.

In December 2025, the FASB issued Accounting Standards Update 2025-12, “Codification Improvements” (“ASU 2025-12”). ASU 2025-12 includes changes that clarify, correct, or otherwise improve certain components of the Accounting Standards Codification. The improvements consist of narrow-scope amendments, technical corrections, clarification of existing guidance, and updates to clarify the appropriate scope and application of certain disclosure requirements. ASU 2025-12 is effective for annual periods beginning after December 15, 2026. We are evaluating the potential impact of ASU 2025-12 on disclosures in our Consolidated Financial Statements which will be effective beginning with our Form 10-K for fiscal year 2028.

**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 2026 Business Acquisition

In June 2026, we (through our Security division) acquired a privately held provider of airport screening services for approximately$27.0 million, plus up to$14.0 million in potential contingent consideration. We paid$26.2 million in cash at the closing of the transaction, with a holdback of$0.8 million expected to be paid in July 2028. The acquisition date fair value of the contingent consideration was$9.7 million. The purchase price of$36.7 million was allocated to net working capital of$2.3 million, intangible assets of$12.5 million and goodwill of$21.9 million. Amortizable intangible assets of$10.2 million have estimated lives ranging from 2 years to 10 years. The acquisition was financed with cash on hand. The goodwill recognized for this business acquisition is deductible for income tax purposes. Revenue and earnings from this acquisition in fiscal year 2026 were not significant.

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. 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$39.2 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. The measurement period ended in September 2025, and no further purchase price adjustments have been recorded since.

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.

Fiscal Year 2024 Business Acquisitions

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.

**3.**BALANCE SHEET DETAILS

The following tables provide details of selected balance sheet accounts (in thousands):

During fiscal 2024, 2025 and 2026, depreciation expense was approximately $19.4 million, $22.0 million and $21.3 million, respectively.

Other accrued expenses and current liabilities included accrued project costs of approximately $21.6 million and $40.1 million as of June 30, 2025 and 2026, respectively. Accrued project costs primarily consist of subcontractor, engineering, materials, installation and other direct costs incurred in fulfilling customer contracts that had not yet been paid as of the end of the period.

**4.**GOODWILL AND INTANGIBLE ASSETS

The changes in the carrying amount of goodwill by segment for fiscal 2025 and 2026 are as follows (in thousands):

Intangible assets consisted of the following (dollar amounts in thousands):

Amortization expense related to intangible assets was $22.8 million, $21.6 million and $21.4 million for fiscal 2024, 2025 and 2026, respectively.

At June 30, 2026, the estimated future amortization expense was as follows (in thousands):

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. During fiscal 2024, 2025 and 2026, we capitalized software development costs in the amounts of $16.6 million, $16.9 million and $17.2 million, respectively.

**5.**CONTRACT ASSETS AND LIABILITIES

The table below shows the balance of contract assets and liabilities as of June 30, 2025 and 2026, including the change between the periods. There were no substantial non-current contract assets for the periods presented.

Contract Assets (dollar amounts in thousands)

Contract Liabilities (dollar amounts in thousands)

*Contract Assets.*Contract assets decreased by approximately $51.8 million as a result of unbilled revenue primarily from the timing and nature of milestones met in contracts for a number of customers in our Security Division, both within the United States and internationally, where we met the contractual terms to prepare invoices to the customers that reduce unbilled revenue, partially offset by transactions where we met the revenue recognition criteria under ASC 606 in advance of the time when contracts give 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 contracts which are fully or partially unsatisfied at the end of the period. As of June 30, 2026 and 2025 the aggregate portion of the transaction price allocated to remaining performance obligations was approximately$1.8 billion. During fiscal 2026, we revised the scope of the disclosure of remaining performance obligations to no longer apply the optional disclosure-only exemption in ASC 606-10-50-14(a) that permits an entity to not disclose information about remaining performance obligations for performance obligations that are part of contracts with an original expected duration of one year or less. We believe this change is preferable under the circumstances because the new disclosure provides more useful information to users of the financial statements by presenting a more comprehensive measure of remaining performance obligations. The prior year amount has been revised to conform to the current year presentation. This change only affected the scope of the disclosure of remaining performance obligations and did not affect revenue recognition, results of operations or financial position. As of June 30, 2026, we expect to recognize revenue on approximately 59% of the remaining performance obligations over the next 12 months, and the remainder is expected to be recognized thereafter. During the fiscal year ended June 30, 2026, we recognized revenue of$110.0 million from contract liabilities existing as of July 1, 2025.

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 ofamortization would be longer than one year. We only give consideration to whether a customer agreement has afinancing component if the period of time between transfer of goods and services and customer payment is greater than one year.

**6.**LEASES

The components of operating lease expense for the fiscal years ended June 30, 2025 and 2026 were as follows (in thousands):

Supplemental balance sheet assets and liabilities related to operating leases were as follows (dollar amounts in thousands):

**8.**BORROWINGS

Long-term debt consisted of the following (in thousands):

Fiscal year principal payments of long-term debt as of June 30, 2026 are as follows (in thousands):

Revolving Credit Facility

In July 2025 we amended and extended our credit facility, now maturing in July 2030, to increase the revolving 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 amargin of 1.25% as of June 30, 2026 (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 June 30, 2026 (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 June 30, 2026, there wereno borrowings outstanding under the revolving credit facility,$95.8 million outstanding under the letters of credit sub-facility, and$92.5 million outstanding under the term loan. As of June 30, 2026, the amount available to borrow under the credit facility was$629.2 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 June 30, 2026, 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 (“2029 Notes”)

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 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 convert all or a portion of their 2029 Notes at their option prior to May 1, 2029, in multiples of $1,000 principal amounts, only under the following circumstances (i) during any calendar quarter commencing after the quarter ended on September 30, 2025 (and only during such 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 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 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 notes called for redemption.

On or after May 1, 2029, the 2029 Notes are convertible 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 June 30, 2026 (in thousands):

The 2029 Notes were not eligible for conversion as of June 30, 2026. No sinking fund is provided for the 2029 Notes, which means that we are not required to redeem or retire them periodically. As of June 30, 2026 we were in compliance with applicable financial covenants under the indenture governing the 2029 Notes.

For the fiscal year ended June 30, 2026, total interest expense for the 2029 Notes was $9.7 million, which consisted of $7.9 million of contractual interest expense and $1.8 million of amortization of debt discount and issuance costs. The unamortized debt issuance cost is amortized on the effective interest method over the life of the 2029 Notes.

0.50% Convertible Senior Notes Due 2031

In November 2025, we issued an aggregate of $575.0 million principal amount of 0.50% convertible senior notes due in February 2031 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act at an issuance price equal to 98% of the principal amount. The 2031 Notes were issued pursuant to and are governed by an indenture dated November 20, 2025. The proceeds from the issuance of the 2031 Notes were approximately $563.0 million, net of the issuance discount and debt issuance costs.

The 2031 Notes are unsecured obligations which bear regular interest at 0.50% per annum payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2026. The 2031 Notes will mature on February 1, 2031, unless repurchased, redeemed, or converted in accordance with their terms prior to such date. The 2031 Notes are convertible into a combination of cash and shares of our common stock, at an initial conversion rate of 2.8263 shares of common stock per $1,000 principal amount of 2031 Notes, which is equivalent to an initial conversion price of approximately $353.82 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 2031 Notes, at our option, on or after February 6, 2029 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 2031 Notes to be redeemed, plus accrued and unpaid interest up to the day before the redemption date. The holders of the 2031 Notes may require us to repurchase the 2031 Notes upon the occurrence of certain fundamental change transactions at a redemption price equal to 100% of the principal amount of the 2031 Notes redeemed, plus accrued and unpaid interest up to the day before the redemption date.

Holders of the 2031 Notes may, at their option, convert all or a portion of their 2031 Notes prior to November 1, 2030, 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 2031 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 2031 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 2031 Notes called for redemption.

On or after November 1, 2030, the 2031 Notes will be 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 2031 Notes who convert the 2031 Notes in connection with a make-whole fundamental change, as defined in the indenture governing the 2031 Notes, or in connection with a redemption may be entitled to an increase in the conversion rate.

We accounted for the issuance of the 2031 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 2031 Notes as of June 30, 2026 (in thousands):

The 2031 Notes were not eligible for conversion as of June 30, 2026. No sinking fund is provided for the 2031 Notes, which means that we are not required to redeem or retire them periodically. As of June 30, 2026 we were in compliance with applicable financial covenants under the indenture governing the 2031 Notes.

For the fiscal year ended June 30, 2026, total interest expense for the 2031 Notes was $3.2 million, which consisted of $1.8 million of contractual interest expense and $1.4 million of amortization of debt discount and issuance costs. The unamortized debt issuance cost is amortized on the effective interest method over the life of the 2031 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 June 30, 2026, $63.0 million was outstanding under these letter-of-credit facilities. As of June 30, 2026, the total amount available under these credit facilities was $57.2 million.

**9.**STOCKHOLDERS’ EQUITY

Stock-based Compensation

As of June 30, 2026, we maintained 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):

As of June 30, 2026, total unrecognized compensation cost related to stock-based compensation grants under the OSI Plan was estimated at$0.9 million for stock options and$13.3 million for restricted stock units (“RSUs”). We expect to recognize these costs over a weighted-average period of 1.87 years with respect to the stock options and 2.2 years for grants of RSUs.

OSI Plan

Awards are granted in the form of incentive options, nonqualified options, stock appreciation rights, RSUs, performance shares and stock bonuses, amongst other forms of equity, to qualified employees, directors and consultants.

Under the OSI Plan, the exercise price of nonqualified options and incentive stock options may not be less than the fair market value of our common stock on the date of grant. The exercise price of nonqualified options and incentive stock options granted to individuals who own more than 10% of ourvoting stock may not be less than 110% of thefair market value of our common stock on the date of grant. Stock options granted under the OSI Plan typically vest over three years based on continued service. Restricted stock and RSUs typically vest over three tofour years based on continued service. Certain restricted stock awards granted to senior management vest based on the achievement of pre-established performance criteria.

Stock Option Fair Value Estimation Assumptions. We estimate the fair value of our stock options at the date of grant using the Black-Scholes option-pricing valuation model. Our valuation model is affected by our stock price as well as weighted average assumptions for a number of subjective variables described below.

Expected Dividend. Expected dividend is based on historical patterns and our anticipated dividend payments over the expected holding period.

Risk-Free Interest Rate. The risk-free interest rate for stock options is based on U.S. Treasuries for a maturity matching the expected holding period.

Expected Volatility. Expected volatility is based on implied volatility and/or our historical share price volatility matching the expected holding period. No single method of estimating volatility is proper under all circumstances and to the extent that a company can derive implied volatility based on the trading of its financial instruments on a public market, it may be appropriate to use both implied and historical volatility in its assumptions. We have certain financial instruments that are publicly traded from which we can derive the implied volatility. Therefore, we use implied and historical volatility for valuing our stock options. We believe that implied and historical volatility is a better indicator of expected volatility because it is generally reflective of both historical volatility and expectations of how future volatility will differ from historical volatility.

Expected Holding Period. We use historical stock option exercise data to estimate the expected holding period.

Changes in assumptions can materially impact the estimated fair value of stock options. The weighted average assumptions used in the valuation model are presented in the table below.

The following summarizes stock option activity for fiscal years 2024, 2025 and 2026:

The per-share weighted-average grant-date fair value of stock options granted under the OSI Plan was $38.28, $55.50 and $90.76 for fiscal 2024, 2025 and 2026, respectively. The total intrinsic value of options exercised during fiscal 2026 was $2.5 million.

Restricted Stock Units—A summary of RSU activity for the periods indicated was as follows:

The per-share weighted average grant-date fair value of RSUs granted under the OSI Plan was $95.42, $127.88, and $226.58 for fiscal 2024, 2025 and 2026, respectively. The total fair value of shares vested during fiscal 2024, 2025 and 2026 was $31.1 million, $41.3 million, and $55.0 million, respectively.

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, resulting in a maximum pool of 9.5 million shares. As of June 30, 2026, there were approximately 1.6 million shares available for grant under the OSI Plan. 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 75,988,80,682, and 49,431 performance-based awards during fiscal 2024, 2025 and 2026, 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.

Employee Stock Purchase Plan

We have an employee stock purchase plan under which eligible employees may purchase a limited number of shares of common stock at a discount of up to 15% of the market value of such stock at pre-determined, plan-defined dates. During the years ended June 30, 2024, 2025 and 2026, employees purchased 63,111,53,697,40,091 shares, respectively. As of June 30, 2026, there were 259,863 shares of our common stock available for issuance under the plan.

Stock Repurchase Program

In September 2022, our Board of Directors increased the stock repurchase authorization to a total oftwo million shares of common stock. This program does not expire unless our Board of Directors acts to terminate the program. The timing and actual numbers of shares purchased depends 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.

On August 20, 2026, we announced that our Board of Directors has approved an additionalone million shares for repurchase under our stock repurchase program, increasing the total remaining authorization to 1,078,731 shares.

During fiscal 2024, 2025 and 2026, we repurchased zero shares,531,314 shares and 1,111,825 shares, respectively, of common stock under our then current programs. As of June 30, 2026, there were 78,731 shares remaining available for repurchase under the authorized repurchase program.

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.**INCOME TAXES

The following is a geographical breakdown of income before the provision for income taxes (in thousands):

Our provision for income taxes consists of the following (in thousands):

Net income tax payments for the year ended June 30, 2026, after the prospective adoption of ASU 2023-09, consisted of the following:

As of June 30, 2025 and 2026, our liability for uncertain tax positions was $15.4 million and $15.2 million, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $14.9 million as of June 30, 2026.

We recognize potential interest and penalties related to income tax matters in income tax expense. As of June 30, 2026, we have accrued $3.2 million for interest and penalties. Our uncertain tax positions are related to tax years that remain subject to examination by the relevant tax authorities. These include fiscal years after 2022 for federal purposes, fiscal years after 2021 for state purposes and fiscal years after 2018 for various foreign jurisdictions. Future developments, such as the settlement of income tax positions or the expiration of applicable statutes of limitation, could result in changes to our liability for unrecognized tax benefits.

A summary of activity of unrecognized tax benefits for fiscal 2025 and 2026 is as follows (in thousands).

Deferred income tax assets (liabilities) consisted of the following (in thousands):

The components of the net deferred income tax asset are classified in the consolidated balance sheets as follows (in thousands):

The components of current taxes receivable and payable and prepaid taxes are classified in the consolidated balance sheets as follows (in thousands):

As of June 30, 2026, we had federal, state and foreign net operating losses carryforwards of approximately $0.3 million, $17.2 million and $7.7 million, respectively. Our net operating loss carryforwards will begin to expire in the tax year ending June 30, 2028. As of June 30, 2026, we had federal and state tax credit carryforwards of approximately $3.8 million and $6.8 million, respectively. Our credit carryforwards will begin to expire in the tax year ending June 30, 2032.

We have established valuation allowances that relate to the net operating losses of certain subsidiaries, capital losses, and tax credits. During the year ended June 30, 2026, we recorded an aggregate net increase of $0.9 million to these valuation allowances. We evaluate the need for valuation allowances on a jurisdiction-by-jurisdiction basis and release such allowances when sufficient positive evidence exists to conclude that it is more likely than not that the deferred tax assets will be realized.

We recognized all excess tax benefits and tax deficiencies related to equity-based compensation as a component of income tax expense or benefit in the period in which they occur, in accordance with ASC 718. An income tax benefit of approximately $1.7 and $2.1 million was recognized in fiscal 2025 and 2026, respectively.

The consolidated effective income tax rate differs from the federal statutory income tax rate due primarily to the following:

The following table provides the disclosures required before adopting ASU 2023-09 and reconciles our effective tax rate with the U.S. federal tax rate:

The provision for income taxes consists of provisions for federal, state, and foreign income taxes. We operate in an international environment with significant operations in various locations outside the U.S. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

**11.**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 caps, the remaining maximum amount of such potential future payments was $51.9 million as of June 30, 2026.

These projections and 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 June 30, 2026 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):

Advances from Customers—We receive advances from customers associated with certain contracts. These advances are paid in cash by customers, and we account for these as liabilities until our contractual obligations are complete.

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 betweenone year andten 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 2026, we had a maximum financial exposure related to performance bonds of approximately$104 million and$102 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 2026.

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 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 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 June 30, 2026.

Legal Proceedings— 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-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.

**12.**RELATED-PARTY TRANSACTIONS

In 1994, we, together with an unrelated company, formed ECIL-Rapiscan Security Products Limited, a joint venture organized under the laws of India. We own a 36% interest in the joint venture, our Executive Chairman owns a 10.5% interest, and our President and Chief Executive Officer owns a 4.5% ownership interest. Our initial investment in the joint venture was approximately $0.1 million. For each of the years ended June 30, 2024, 2025 and 2026 our equity earnings in the joint venture were not significant. We, our Executive Chairman and our and President and Chief Executive Officer collectively control less than 50% of the board of directors voting power in the joint venture. As a result, we account for the investment under the equity method of accounting. The joint venture was formed for the purpose of the manufacture, assembly, service and testing of security and inspection systems and other products. Some of our subsidiaries are suppliers to the joint venture partner, which in turn manufactures and sells the resulting products. Net sales to the joint venture partner for fiscal 2024, 2025 and 2026 were approximately $10.4 million, $6.0 million and $1.8 million, respectively. Receivables from the joint venture were $3.5 million and $1.8 million as of June 30, 2025 and 2026, respectively.

**13.**EMPLOYEE BENEFIT PLANS

Employee Retirement Savings Plans

We have various qualified employee retirement savings plans. Participants can contribute certain amounts to the plans and we match a certain portion of employee contributions. We contributed approximately $7.4 million, $8.8 million and $9.5 million to the plans for the fiscal years ended June 30, 2024, 2025 and 2026, respectively.

Deferred Compensation Plan

We have a deferred compensation plan, which meets the requirements for deferred compensation under Section 409A of the Internal Revenue Code. The plan provides that selected employees are eligible to defer up to 80% of their salaries and up to 100% of their bonuses. We may also make employer contributions to participant accounts in certain circumstances. The benefits under this plan are unsecured. Participants are generally eligible to receive payment of their vested benefit at the end of their elected deferral period or after termination of their employment for any reason or at a later date to comply with the restrictions of Section 409A. Discretionary company contributions and the related earnings are subject to a vesting schedule dependent upon years of service to us and, also, vest completely upon the participant’s disability or death while employed by us or immediately prior to a change of control. We made contributions of $0.7 million, $0.7 million and $0.8 million for fiscal year 2024, 2025 and 2026, respectively. As of June 30, 2026, we held assets of $55.0 million and liabilities of $53.8 million related to this plan. Assets related to this plan are included in other assets and liabilities related to this plan are included in other long-term liabilities in the consolidated balance sheets. The plan liabilities include accrued employer contributions not yet funded to the plan.

Employee Pension Plans

We sponsor a number of qualified and nonqualified pension plans for our employees at certain locations. In accordance with accounting standards for employee pension and postretirement benefits, we fully recognize the overfunded or underfunded status of each of our defined benefit plans as an asset or liability in the consolidated balance sheets. The asset or liability equals the difference between the fair value of the plans’ assets and their benefit obligations. The liabilities associated with underfunded plans are classified as noncurrent, except to the extent the fair value of the plans’ assets is less than the plans’ estimated benefit payments over the next 12 months. We measure our pension and postretirement benefit plans’ assets and benefit obligations as of June 30.

The following provides a reconciliation of the changes in the plans’ benefit obligations and fair value of assets for fiscal years 2025 and 2026, and a statement of the funded status as of June 30, 2025 and 2026 (in thousands):

One of our defined benefit pension plans is considered a nonqualified plan, therefore we have funded a separate rabbi trust which comprises insurance company contracts with fair values of $9.1 million and $10.7 million as of June 30, 2025 and 2026, respectively, included in Other Assets on the consolidated balance sheets. These amounts are not included in the fair value of plan assets in the table above. In the fiscal year ended June 30, 2026, $2.1 million from the rabbi trust was used as a Company contribution to the nonqualified plan and paid during the year.

The following table provides the net periodic benefit costs for the fiscal years ended June 30, (in thousands):

Plan Assumptions

The long-term return on assets has been derived from the weighted average of assumed returns on each of the major asset categories. The weighted average is based on the actual proportion of each major asset class held, rather than a benchmark portfolio of assets. The expected returns for each major asset class have been derived from a combination of both historical market returns and current market data as well as the views of a range of investment managers. There is no assumed rate of compensation increase as most of the plan participants are retirees or no longer employed by OSI.

Plan Assets and Investment Policy

The defined benefit plans’ assets are invested in a range of pooled investment funds that provide access to a diverse range of asset classes. The investment objective is to maximize the investment return over the long term without exposing the fund to an unnecessary level of risk. Within this objective, it is recognized that benefits will be secured by the purchase of annuities at the time of employee retirement.

The benchmark is to hold assets in both equity and debt securities. The proportion in each investment class is not mandated and is allowed to fluctuate with market movements. The equity holdings are maintained in balanced funds under the control of investment managers.

Day-to-day equities selection decisions are delegated to investment managers, although these are monitored against performance and risk targets. Due to the nature of the pooled funds, there are no significant holdings in any single company (greater than 5% of the total assets). The investment strategy is reviewed on a regular basis, based on the results of third-party liability studies.

Projected Benefit Payments

The following table reflects estimated benefits payments, based upon the same assumptions used to measure the benefit obligation and net pension cost, as of June 30, 2026 (in thousands):

Company Contribution

A contribution of $2.1 million during fiscal year 2026 for the nonqualified plan was provided by the rabbi trust as described above. Future contributions for the nonqualified plan are expected to be provided by the rabbi trust.

Plan Amendment

In December 2025, a plan amendment was made for our former CEO resulting in $4.4 million in prior service costs amortization.

**14.**SEGMENT INFORMATION

We operate inthree 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). Factors used to identify our reportable segments primarily reflect our organizational and management structure around differences in products and industry markets. The reconciliation of segment totals to consolidated totals include intersegment eliminations and certain unallocated corporate items that include executive compensation and certain other general and administrative expenses; expenses related to stock issuances, legal, audit and other professional service fees, depreciation and amortization, and corporate assets. 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, Summary of Significant Accounting Policies. 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 impairment, restructuring and other charges presented below which are presented to reconcile to consolidated income from operations. Segment assets represent total current and noncurrent assets for each reportable segment. 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 assets and 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.
