We were incorporated in California in 1989 and re-incorporated in Delaware in 2000.

Basis of Presentation

The consolidated financial statements include the accounts of Lantronix and our wholly owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The industry in which we operate is characterized by rapid technological change. As a result, estimates made in preparing the consolidated financial statements include revenue recognition, the allowance for doubtful accounts, inventory valuation, goodwill valuation, deferred income tax asset valuation allowances, restructuring charges and warranty reserves. To the extent there are material differences between our estimates and actual results, future results of operations will be affected.

Revenue Recognition

Refer toNote 2 below for a discussion of our significant accounting policy over revenue recognition.

Accounts Receivable and Allowance for Credit Losses

Accounts receivable are stated at the amount we expect to collect, which is net of an allowance for credit losses for estimated losses resulting from the inability of our customers to make required payments. Our evaluation of the collectability of customer accounts receivable is based on various factors. In cases where we are aware of circumstances that may impair a specific customer’s ability to meet its financial obligations subsequent to the original sale, we record an allowance against amounts due based on those particular circumstances. For all other customers, we estimate an allowance for credit losses based on various considerations, including the length of time the receivables are past due and our historical bad debt collection experience. We also consider our understanding of current economic and industry conditions, as well as reasonable and supportable forecasts of future economic conditions that may affect the collectability of customer receivables. Accounts that are deemed uncollectible are written off against the allowance for credit losses.

Concentration of Credit Risk

Our accounts receivable are primarily derived from revenue earned from customers located throughout North America, Europe and Asia. We perform periodic credit evaluations of our customers’ financial condition and maintain allowances for potential credit losses. Credit losses have historically been within our expectations. We generally do not require collateral or other security from our customers.

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts receivable, contract manufacturers’ receivable, accounts payable, and accrued liabilities. The fair value of a financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants. Assets and liabilities measured at fair value are categorized based on whether or not the inputs are observable in the market and the degree to which the inputs are observable. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) defined as follows:

Level 1: Inputs are based on quoted market prices for identical assets and liabilities in active markets at the measurement date.

Level 2: Inputs include quoted prices for similar assets or liabilities in active markets and/or quoted prices for identical or similar assets or liabilities in markets that are not active near the measurement date.

Level 3: Inputs include management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation.

During the fiscal years ended June 30, 2026 and 2025 we did not have any assets or liabilities that were measured at fair value on a recurring basis. As of June 30, 2026 we do not have any assets or liabilities that were measured at fair value on a non-recurring basis.

We believe all of our financial instruments’ recorded values approximate their current fair values because of the nature and short duration of these instruments.

Foreign Currency Remeasurement

The functional currency for all our foreign subsidiaries is currently the U.S. dollar. Non-monetary and monetary foreign currency assets and liabilities are valued in U.S. dollars at historical and end-of-period exchange rates, respectively. Exchange gains and losses from foreign currency transactions and remeasurements are recognized in the consolidated statements of operations. Translation adjustments for foreign subsidiaries whose functional currencies were previously their respective local currencies are suspended in accumulated other comprehensive income.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income is composed of accumulated translation adjustments as of June 30, 2026 and 2025. As a result of the final dissolution of a foreign subsidiary during the fiscal year ended June 30, 2026, we reclassified to other income $27,000 in accumulated foreign currency translation adjustments related to this subsidiary that were previously suspended in accumulated other comprehensive income. We didnot have any other comprehensive income or losses during the fiscal years ended June 30, 2026 or 2025.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and short-term investments, with original maturities of 90 days or less.

Inventories

Inventories are stated at the lower of cost or net realizable value, cost being determined on a weighted-average cost basis that approximates the first-in, first-out method. We provide reserves for excess and obsolete inventories determined primarily based upon estimates of future demand for our products.

Inventory Sale and Purchase Transactions with Contract Manufacturers

Under certain circumstances, we sell raw materials to our contract manufacturers and subsequently repurchase finished goods from the contract manufacturers which contain such raw materials. Net sales of raw materials to the contract manufacturers are recorded on the consolidated balance sheets as contract manufacturers’ receivables and are eliminated from net revenue as we intend to repurchase the raw materials from the contract manufacturers in the form of finished goods.

We have contractual arrangements with certain of our contract manufacturers that require us to purchase unused inventory that the contract manufacturer has purchased to fulfill our forecasted manufacturing demand. To the extent that inventory on-hand at one or more of these contract manufacturers exceeds our contractually reported forecasts, we record the amount we may be required to purchase as part of other current liabilities and inventories on the consolidated balance sheets.

Property and Equipment

Property and equipment are carried at cost. Depreciation is provided using the straight-line method over the assets’ estimated useful lives, generally ranging from three to five years. Depreciation and amortization of leasehold improvements are computed using the shorter of the remaining lease term or five years. Major renewals and betterments are capitalized, while replacements, maintenance and repairs, which do not improve or extend the estimated useful lives of the respective assets, are expensed as incurred.

**Goodwill **

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets acquired. We evaluate goodwill for impairment on an annual basis as of May 31, or more frequently if we believe indicators of impairment exist that would more likely than not reduce the fair value of our single reporting unit below its carrying amount. We begin by assessing qualitative factors to determine whether it is more likely than not that the fair value of our single reporting unit is less than its carrying value. Based on that qualitative assessment, if we conclude that it is more likely than not that the fair value of our single reporting unit is less than its carrying value, we conduct a quantitative goodwill impairment test, which involves comparing the estimated fair value of our single reporting unit with its carrying value, including goodwill. We estimate the fair value of our single reporting unit using a combination of the income and market approach. If the carrying value of the reporting unit exceeds its estimated fair value, we recognize an impairment loss for the difference.

Significant management judgment is required in estimating the reporting unit’s fair value and in the creation of the forecasts of future operating results that are used in the discounted cash flow method of valuation. These include (i) estimation of future cash flows, which is dependent on internal forecasts, (ii) estimation of the long-term rate of growth of our business, (iii) estimation of the period during which cash flows will be generated and (iv) the determination of our weighted-average cost of capital, which is a factor in determining the discount rate. Our estimate of the reporting unit’s fair value would also generally include the consideration of a control premium, which is the amount that a buyer is willing to pay over the current market price of a company as indicated by the traded price per share (i.e., market capitalization) to acquire a controlling interest. If our actual financial results are not consistent with our assumptions and judgments used in estimating the fair value of our reporting unit, we may be exposed to goodwill impairment losses.

During the fourth quarter of fiscal 2026, we made a qualitative assessment of whether goodwill impairment existed. Since our assessment of the qualitative factors did not result in a determination that it was more likely than not that the fair value of our single reporting unit is less than its carrying value, we were not required to perform the quantitative goodwill impairment test.

Intangible Assets

Included within “intangible assets, net” at June 30, 2026 are customer relationships, developed technology, trademarks and trade names, and other intangible assets acquired in connection with various business combinations. Such capitalized costs and intangible assets are being amortized over a period of one to fourteen years.

**Impairment of Long-Lived Assets **

We assess the impairment of long-lived assets, including intangible assets, whenever events or changes in circumstances indicate that the carrying amount of long-lived assets within an asset group may not be recoverable. We estimate the future cash flows, undiscounted and without interest charges, expected to be generated by the assets from its use over its remaining useful life and eventual disposition. If the sum of the expected undiscounted future cash flows is less than the carrying amount of those assets, we estimate the fair value of the asset group and recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.

Income Taxes

Income taxes are computed under the liability method. This method requires the recognition of deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities. The impact on deferred taxes of changes in tax rates and laws, if any, are applied to the years during which temporary differences are expected to be settled and are reflected in the consolidated financial statements in the period of enactment. A valuation allowance is recorded when it is more likely than not that some of the deferred tax assets will not be realized.

Financial statement effects of a tax position are initially recognized when it is more likely than not, based on the technical merits, that the position will be sustained upon examination by a taxing authority. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that meets the more-likely-than-not threshold of being realized upon ultimate settlement with a taxing authority. We recognize potential accrued interest and penalties related to unrecognized tax benefits as income tax expense.

Share-Based Compensation

We account for share-based compensation by expensing the estimated grant date fair value of our share-based awards ratably over the requisite service period.

The fair value of our restricted stock units is based on the closing market price of our common stock on the date of grant.

The fair value of our performance stock units is estimated as of the grant date based upon the expected achievement of the performance metrics specified in the grant and the closing market price of our common stock on the date of grant. To the extent a grant of performance stock units contains a market condition, the grant date fair value is estimated using a Monte Carlo simulation, which incorporates estimates of the potential outcomes of the market condition on the grant date fair value of each award.

We recognize the impact of forfeitures on our share-based compensation expense as such forfeitures occur. Previously recognized expense is reversed for the portion of awards forfeited prior to vesting.

Net Income (Loss) Per Share

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the fiscal year. Diluted net income (loss) per share is calculated by adjusting the weighted-average number of common shares outstanding, assuming any dilutive effects of outstanding share-based awards using the treasury stock method.

Research and Development Costs

Costs incurred in the research and development of new products and enhancements to existing products are expensed as incurred. Development costs of computer software to be sold, leased or otherwise marketed are subject to capitalization beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. In most instances, we believe our current process for developing products is essentially completed concurrently with the establishment of technological feasibility and thus, software development costs have been expensed as incurred.

Warranty

The standard warranty periods we provide for our products typically range from one to five years. We establish reserves for estimated product warranty costs at the time revenue is recognized based upon our historical warranty experience, and for any known or anticipated product warranty issues. If actual return rates and/or replacement costs differ significantly from our estimates, adjustments to recognize additional warranty expense in cost of revenue may be required in future periods.

Restructuring Charges

We recognize costs and related liabilities for restructuring activities when they are incurred. Our restructuring charges are primarily comprised of employee separation costs, asset impairments and contract exit costs. Employee separation costs include one-time termination benefits that are recognized as a liability at estimated fair value, at the time of communication to employees, unless future service is required, in which case the costs are recognized ratably over the future service period. Ongoing termination benefits are recognized as a liability at estimated fair value when the amount of such benefits are probable and reasonably estimable. Contract exit costs include contract termination fees and right-of-use asset impairments recognized on the date that we have vacated the premises or ceased use of the leased facilities. A liability for contract termination fees is recognized in the period in which we terminate the contract.

Leases

We determine if an arrangement is a lease, or contains a lease, at the inception of the arrangement and evaluate whether the lease is an operating lease or a finance lease at the commencement date. We recognize right-of-use (“ROU”) assets and lease liabilities for operating and finance leases with terms greater than 12 months. ROU assets represent our right to use an asset for the lease term, while lease liabilities represent our obligation to make lease payments. To the extent a lease includes a renewal option, we include such options in the calculation of the ROU asset and lease liability if it is reasonably assured that we will exercise the option. Operating and finance lease ROU assets and liabilities are recognized based on the present value of lease payments over the lease term at the lease commencement date. We do not separate lease and nonlease components of contracts. To determine the present value of lease payments, we use the implicit interest rate, if it is readily determinable or estimable. To the extent that we are unable to utilize an interest rate implicit in the lease, we generally use our collateralized incremental borrowing rate based on the information available at the lease commencement date, including lease term, in determining the present value of lease payments. Operating and finance lease ROU assets are recognized net of any lease prepayments and incentives. Operating lease expense is recognized on a straight-line basis over the lease term. Finance lease expense is recognized based on the effective-interest method over the lease term.

For leases that we acquire in acquisition transactions, we generally elect not to recognize assets or liabilities at the acquisition date for leases that, at the acquisition date, have a remaining lease term of 12 months or less.

Refer toNote 8 below for additional information regarding our leases.

Advertising Expenses

Advertising expenses are recorded in the period incurred and totaled $169,000 and $224,000 for the fiscal years ended June 30, 2026 and 2025, respectively. The costs are included in selling, general and administrative expenses in the consolidated statements of operations.

Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), who is our Chief Executive Officer, in deciding how to allocate resources and assess our financial and operational performance. Our CODM evaluates our financial information, such as revenue, gross profit and net income (loss), as well as resources and total consolidated assets and assesses the performance of these resources and assets on a consolidated and aggregated basis. As a result, we have determined that our business operates in asingle operating segment: the development, marketing, and sale of industrial and enterprise IoT products and services.

Recent Accounting Pronouncements

Credit Losses

In July 2025, the Financial Accounting Standards Board (“FASB”) issued a final Accounting Standards Update (“ASU”) amending Accounting Standards Codification (“ASC”) 326, Financial Instruments – Credit Losses, to allow all entities to elect a practical expedient when determining the expected credit losses on trade accounts receivable. The practical expedient allows companies to assume that the current conditions as of the balance sheet date will remain unchanged through the remaining life of the asset. The standard will be effective for Lantronix beginning with our interim financial statements for the fiscal year ending June 30, 2027. The impact of adopting this guidance is not expected to have a material effect on our consolidated financial statements.

Income Tax Disclosures

In December 2023, the FASB issued a final standard on improvements to income tax disclosures. The new standard requires disaggregated information about a company’s effective tax rate reconciliation and information on income taxes paid. The standard became effective for Lantronix on a prospective basis beginning with our annual financial statements for the fiscal year ended June 30, 2026. The impact of adopting this guidance did not have a material impact on our consolidated financial position and results of operations, since it requires only enhancements to existing income tax disclosures in the footnotes to our consolidated financial statements.

Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU 2024-03, which will require disclosure, in the notes to financial statements, of specified information about certain costs and expenses, including disclosure of amounts for (i) purchases of inventory, (ii) employee compensation, (iii) depreciation and (iv) intangible asset amortization, included in each relevant expense caption. In January 2025, the FASB issued ASU 2025-01, which clarified the effective date of ASU 2024-03. The standard will be effective for our annual financial statements beginning in the fiscal year ending June 30, 2028. We are currently evaluating the impact of this accounting standard on our financial statement presentation and its related disclosures.

Revenue is recognized upon the transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We apply the following five-step approach in determining the amount and timing of revenue to be recognized: (i) identifying the contract with a customer, (ii) identifying the performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to the performance obligations in the contract and (v) recognizing revenue when the performance obligations are satisfied. On occasion we enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations.

Revenue is recognized exclusive of (i) any taxes collected from customers, which are subsequently remitted to governmental authorities and (ii) shipping and handling costs collected from customers.

Products

Most of our product revenue is recognized as a distinct single performance obligation when products are tendered to a carrier for delivery, which represents the point in time that our customer obtains control of the promised products. A smaller portion of our product revenue is recognized when our customer receives delivery of the promised products.

A significant portion of our products are sold to distributors under agreements which contain (i) limited rights to return unsold products and (ii) price adjustment provisions, both of which are accounted for as variable consideration when estimating the amount of revenue to recognize. We base our estimates for returns and price adjustments primarily on historical experience; however, we also consider contractual allowances, approved pricing adjustments and other known or anticipated returns and price adjustments in a given period. Such estimates are generally made at the time of shipment to the customer and updated at the end of each reporting period as additional information becomes available and only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. Our estimates of accrued variable consideration are included in other current liabilities in the accompanying consolidated balance sheets.

Services

Revenues from our extended warranty, technical support, and maintenance services are generally recognized ratably over the applicable service period. Although not significant to date, revenues from sales of our software-as-a-service (“SaaS”) solutions are recognized ratably over the applicable service period as well.

We prepay sales commissions related to certain of these contracts, which are incremental costs of obtaining the contract. We capitalize these costs and expense them ratably on a straight-line basis over the life of the contract. At June 30, 2026, prepaid sales commissions included in prepaid expenses and other current assets totaled $95,000 and included in other assets totaled $127,000. At June 30, 2025, prepaid sales commissions included in prepaid expenses and other current assets totaled $404,000 and included in other assets totaled $134,000.

Engineering Services

We derive a portion of our revenues from engineering and related consulting service contracts with customers. Revenues from professional engineering services are generally recognized as services are performed. These contracts generally include performance obligations in which control is transferred over time because the customer either simultaneously receives and consumes the benefits provided or our performance on the contract creates or enhances an asset that the customer controls. These contracts typically provide services on the following basis:

Performance obligations for T&M contracts qualify for the “Right to Invoice” practical expedient within the revenue guidance. Under this practical expedient, we may recognize revenue, over time, in the amount to which we have a right to invoice. In addition, we are not required to estimate variable consideration upon inception of the contract and reassess the estimate each reporting period. We have determined that this method best represents the transfer of services as, upon billing, we have a right to consideration from a customer in an amount that directly corresponds with the value to the customer of our performance completed to date.

We recognize revenue on fixed price contracts, over time, using an input method based on the proportion of our actual costs incurred (generally labor hours expended) to the total costs expected to complete the contract performance obligation. We have determined that this method best represents the transfer of services as the proportion closely depicts the efforts or inputs completed towards the satisfaction of a fixed price contract performance obligation.

Multiple Performance Obligations

From time to time, we may enter into contracts with customers that include promises to transfer multiple deliverables that may include sales of products, professional engineering services and other product qualification or certification services. Determining whether the deliverables in such arrangements are considered distinct performance obligations that should be accounted for separately versus together often requires judgment. We consider performance obligations to be distinct when the customer can benefit from the promised good or service on its own or by combining it with other resources readily available and when the promised good or service is separately identifiable from other promised goods or services in the contract. In such arrangements, we allocate revenue on a relative standalone selling price basis by maximizing the use of observable inputs to determine the standalone selling price for each performance obligation.

Net Revenue by Product Line and Geographic Region

We organize our products and solutions into three product lines: Embedded IoT Solutions, IoT System Solutions, and Software & Services. Our Embedded IoT products are normally embedded into new designs. These products include application processing that delivers compute to meet customer needs for data transformation, computer vision, machine learning, augmented / virtual reality, audio / video aggregation and distribution, and custom applications at the edge. Our IoT System products include wired and wireless connections that enhance the value and utility of modern electronic systems and equipment by providing secure network connectivity, power for IoT end devices through Power over Ethernet (“PoE”), application hosting, protocol conversion, media conversion, secure access for distributed IoT deployments and many other functions. Our Software & Services products can be classified as either (i) our SaaS platform, which enables customers to easily deploy, monitor, manage, and automate across their global deployments, all from a single platform login, virtually connected as though directly on each device, (ii) engineering services, which is a flexible business model that allows customers to select from turnkey product development or team augmentation for accelerating complex areas of product development or (iii) extended warranty, support and maintenance.

We conduct our business globally and manage our sales teams by three geographic regions: the Americas; Europe, Middle East, and Africa (“EMEA”); and Asia Pacific Japan (“APJ”).

The following tables present our net revenue by product line and by geographic region. We present net revenues by geographic region generally based on the “ship-to” location of our customers for product sales and the “bill-to” location for services:

The following table presents product revenues and service revenues as a percentage of our total net revenue:

Service revenues are comprised primarily of professional services, software license subscriptions, and extended warranties.

Contract Balances

In certain instances, the timing of revenue recognition may differ from the timing of invoicing to our customers. We record a contract asset receivable when revenue is recognized prior to invoicing, and a contract or deferred revenue liability when revenue is recognized subsequent to invoicing. With respect to product shipments, we expect to fulfill contract obligations within one year and so we have elected not to separately disclose the amount nor the timing of recognition of these remaining performance obligations. For contract balances related to contracts that include services and multiple performance obligations, refer to the deferred revenue discussion below.

Deferred Revenue

Deferred revenue is primarily comprised of unearned revenue related to our extended warranty, support and maintenance services and certain software services. These services are generally invoiced at the beginning of the contract period and revenue is recognized ratably over the service period. Current and non-current deferred revenue balances represent revenue allocated to the remaining unsatisfied performance obligations at the end of a reporting period and are respectively included in other current liabilities and other non-current liabilities in the accompanying consolidated balance sheets.

The following table presents the changes in our deferred revenue balance:

During the years ended June 30, 2026 and 2025, approximately $2,418,000 and $3,000,000, respectively, of the revenue recognized as a result of satisfying performance obligations was included in the contract liability balance at the beginning of the period.

We currently expect to recognize substantially all of the non-current portion of deferred revenue over the next 2 to 5 years.

Bank Line of Credit

On August 15, 2025, we entered into a Fourth Amended and Restated Loan and Security Agreement (the “Prior Loan Agreement”) with Silicon Valley Bank (“SVB”), which effectively refinanced our outstanding term loan with an asset-backed revolving line of credit secured by our accounts receivable. The line provided us with a revolving credit facility of up to $15,000,000, subject to customary borrowing base limitations. The revolving credit facility was scheduled to mature on August 1, 2028. Borrowings under the revolving credit facility bore interest on the outstanding principal equal to the greater of (i) 5.0% and (ii) the Prime Rate, as defined in the Prior Loan Agreement, plus a margin of 0.0% to 0.5%, with the applicable margin depending on our liquidity.

The Prior Loan Agreement required us to comply with a minimum liquidity test. The Prior Loan Agreement also included customary representations and warranties and affirmative and negative covenants, including covenants that limited or restricted our ability to incur liens or indebtedness, dispose of assets, make investments, make restricted payments, merge or consolidate, and enter into certain transactions with our affiliates. The Prior Loan Agreement also included customary events of default, including, among other things, non-payment defaults, covenant defaults, bankruptcy and insolvency defaults, and material judgment defaults. If any event of default under the Prior Loan Agreement had occurred (subject, in certain instances, to specified grace or cure periods), the principal, interest and any other monetary obligations on all the then outstanding amounts would have become due and payable immediately.

The following table summarizes our outstanding debt:

During the years ended June 30, 2026 and 2025, we recognized $539,000 and $1,238,000, respectively, of interest expense in the accompanying consolidated statements of operations related to interest and amortization of issuance costs associated with debt. As of June 30, 2026 the available borrowing capacity on the line of credit was $13,591,000.

Financial Covenants

The Prior Loan Agreement required Lantronix to comply with a minimum liquidity test and a minimum interest coverage ratio.

Liquidity

The Prior Loan Agreement required that we maintain a minimum liquidity of $5,000,000 at SVB, as measured at the end of each month.

Interest Coverage ratio

The Prior Loan Agreement required that we maintain a minimum interest coverage ratio, calculated as the ratio of interest expense for the trailing 12-month period to the consolidated trailing 12-month earnings before interest, taxes, depreciation and amortization, and certain other allowable exclusions of 1.50 to 1.00 for each calendar quarter.

As of June 30, 2026 we were in compliance with all financial covenants under the Prior Loan Agreement.

Fifth Amended and Restated Loan and Security Agreement

On July 31, 2026, we entered into a Fifth Amended and Restated Loan and Security Agreement (the “Amended Loan Agreement”) with SVB, pertaining to our existing revolving credit facility and term loan (together, the “Senior Credit Facilities”). The Amended Loan Agreement amends and restates in its entirety the Prior Loan Agreement.

The Amended Loan Agreement provides for a $15,000,000 revolving credit facility and a $5,000,000 term loan. The revolving credit facility and term loan each mature on August 1, 2028. The term loan requires quarterly principal payments of $62,500 commencing after funding, which occurred in August 2026, with the remaining outstanding principal due at maturity.

Borrowings under the Senior Credit Facilities bear interest at a floating rate equal to the greater of (i) 5.0% or (ii) the Prime Rate plus an applicable margin.

In addition to the existing financial covenants under the Amended Loan Agreement, the Amended Loan Agreement requires that we maintain a minimum liquidity coverage ratio of 2.0 to 1.0, as measured at the end of each month.

Public Offerings

Underwritten Offering

On May 29, 2026, in an underwritten public offering, we sold approximately 4,800,000 shares of common stock at $7.20 per share resulting in gross proceeds of $34,500,000, prior to payment of the underwriter fees of $1,750,000 and approximately $1,000,000 of other offering expenses.

Sales Agreement

On May 8, 2026, we entered into a sales agreement with sales agents, with respect to an at-the-market offering program under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, with an aggregate offering price of up to $30,000,000.

During the year ended June 30, 2026, we sold approximately 1.8 million shares of our common stock under the sales agreement generating approximately $13,030,000 in gross proceeds and incurred $390,000 in related commissions and $300,000 transaction fees. As of June 30, 2026, we have approximately $17,000,000 remaining of the aggregate offering capacity and the sales agreement remains in effect.

Stock Incentive Plans

We have stock incentive plans in effect under which non-qualified and incentive stock options to purchase shares of Lantronix common stock (“stock options”) have been granted to employees, non-employees and board members. In addition, we have previously granted restricted common stock awards (“non-vested shares”) to employees and board members under these plans. In November 2020, our stockholders voted to approve the 2020 Performance Incentive Plan (the “2020 Plan”), replacing our Amended and Restated 2010 Stock Incentive Plan (the “2010 Plan”), which expired in September 2020. At the 2010 Plan’s expiration date, approximately 1,097,000 shares of our common stock that remained available for award grants under the 2010 Plan became available for award grants under the 2020 Plan. An additional 2,500,000 shares of our common stock were also made available at that time for award grants under the 2020 Plan, and shares of common stock subject to outstanding awards under the 2010 Plan that expired, were cancelled, or otherwise terminate after the expiration date of the 2010 Plan became available for award grant purposes under the 2020 Plan. In both November 2022 and November 2024, our stockholders voted to approve amendments to the 2020 Plan that, among other things, increased the aggregate number of shares of our common stock available for award grants under the plan in each case by 1,800,000 shares, for a total increase of 3,600,000 shares. The 2020 Plan authorizes awards of stock options (both non-qualified and incentive), stock appreciation rights, non-vested shares, restricted stock units (“RSUs”) and performance shares (“PSUs”). New shares are issued to satisfy stock option exercises and share issuances. At June 30, 2026, approximately 645,000 shares remain available for issuance under the 2020 Plan. We have also granted stock options, RSUs and PSUs under individual inducement award agreements.

The Compensation Committee of our board of directors determines eligibility, vesting schedules and exercise prices for stock options and shares granted under the plans. Stock options are generally granted with an exercise price equal to the market price of our common stock on the grant date. Stock options generally have a contractual term of seven to ten years. Share-based awards generally vest and become exercisable over a one to four-year service period. As of June 30, 2026, no stock appreciation rights or non-vested stock was outstanding. No income tax benefit was realized from activity in the share-based plans during the fiscal years ended June 30, 2026 and 2025.

Restricted Stock Units

The fair value of our RSUs is based on the closing market price of our common stock on the grant date.

The following table presents a summary of activity with respect to our RSUs:

Performance Shares

The fair value of our PSUs is estimated as of the grant date based upon the expected achievement of the performance metrics specified in the grant and the closing market price of our common stock on the date of grant. To the extent a grant of PSUs contains a market condition, the grant date fair value is estimated using a Monte Carlo simulation with the following weighted average assumptions:

The following table presents a summary of activity with respect to our PSUs:

Stock Option Awards

The fair value of each stock option grant is estimated on the grant date using the Black-Scholes-Merton option-pricing formula. The expected term of stock options granted is based on our recent historical exercise data. Expected volatilities are based on the historical volatility of our stock price. The risk-free interest rate assumption is based on the U.S. Treasury interest rates appropriate for the expected term of our stock options.

The following table presents a summary of activity for all of our stock options:

The following table presents a summary of grant date fair value and intrinsic value information for all of our stock options:

Employee Stock Purchase Plan

Our 2013 Employee Stock Purchase Plan (“ESPP”) is intended to provide employees with an opportunity to purchase our common stock through accumulated payroll deductions at the end of a specified purchase period. Each of our employees (including officers) is eligible to participate in our ESPP, subject to certain limitations as set forth in our ESPP.

After the purchase and issuance of shares that occurred in May 2025, the ESPP has been suspended until further notice.

Before suspension The ESPP operated with six month offering periods commencing on the first trading day on or after May 16 and November 16 of each year (an “Offering Period”). Common stock might have been purchased under the ESPP at the end of each six-month Offering Period unless the participant withdrew or terminated employment earlier. Shares of the Company’s common stock might have been purchased under the ESPP at a price not less than 85% of the lesser of the fair market value of our common stock on the first or last trading day of each Offering Period. The ESPP limited the number of shares of common stock that might have been issued under the plan to 1,800,000 shares.

The per share fair value of stock purchase rights granted under the ESPP was estimated using the following weighted-average assumptions:

The following table presents a summary of activity under our ESPP:

Share-Based Compensation Expense

The following table presents a summary of share-based compensation expense included in each applicable functional line item on our consolidated statements of operations:

The following table presents a summary of the remaining unrecognized share-based compensation expense related to our outstanding share-based awards as of June 30, 2026:

If there are any modifications or cancellations of the underlying unvested share-based awards, we may be required to accelerate, increase or cancel remaining unearned share-based compensation expense. Future share-based compensation expense and unearned share-based compensation expense will increase to the extent that we grant additional share-based awards.

We have a retirement savings plan (the “Plan”) to which eligible employees may elect to make contributions through salary deferrals up to 100% of their base pay, subject to limitations. We made approximately $316,000 and $364,000 in matching contributions to participants in the Plan during the fiscal years ended June 30, 2026 and 2025, respectively.

In addition, we may make discretionary profit-sharing contributions, subject to limitations. During the fiscal years ended June 30, 2026 and 2025, we made no such contributions to the Plan.

The provision (benefit) for income taxes consists of the following components:

The following table presents U.S. and foreign income (loss) before income taxes:

The tax effects of temporary differences that give rise to deferred tax assets and liabilities are as follows:

Our net deferred tax liability of $219,000 and $172,000 at June 30, 2026 and 2025, respectively, represents the excess of our indefinite-lived deferred tax liabilities over our indefinite-lived deferred tax assets, and are recorded in other non-current liabilities on the accompanying consolidated balance sheets at June 30, 2026 and 2025. Realization of deferred tax assets is dependent upon the generation of future taxable income. As required by ASC 740, we have evaluated the positive and negative evidence bearing upon our ability to realize the deferred tax assets as of June 30, 2026 and 2025. We have determined that it was more likely than not that Lantronix would not realize the deferred tax assets due to our cumulative losses and uncertainty of generating future taxable income.

We adopted ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” on a prospective basis beginning with year ended June 30, 2026. The following table presents required disclosure pursuant to ASU 2023-09 and reconciles the U.S. federal statutory tax amount and rate to our actual global effective amount and rate for the year ended June 30, 2026:

• State tax in California, Illinois and Texas represented more than 50% of the tax effect in this reconciling item

The following table presents a reconciliation of the provision (benefit) for income taxes to taxes computed at the U.S. federal statutory rate before adoption of ASU 2023-09:

We continue to assert that our foreign earnings are indefinitely reinvested in our overseas operations and as such, deferred income taxes were not provided on undistributed earnings of certain foreign subsidiaries. The 2017 Tax Cuts and Jobs Act (the “2017 Act”) created a requirement that certain income earned by foreign subsidiaries, known as global intangible low-tax income (“GILTI”), must be included in the gross income of their U.S. shareholder. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or recognizing such taxes as a current-period expense when incurred. During the fiscal years ended June 30, 2026 and 2025, we elected to treat the tax effect of GILTI as a current-period expense when incurred.

At June 30, 2026, we had federal net operating loss (“NOL”) carryforwards of $27,074,000 and state net operating loss carryforwards of $11,825,000. Our federal net operating loss carryforwards generated for tax years beginning before July 1, 2018 continue to expire in future fiscal years. Pursuant to the 2017 Act, we also have federal NOL carryforwards of $9,024,000 that will not expire but can only be used to offset 80% of future taxable income. For state income tax purposes, our NOL carryforwards continue to expire in future fiscal years. A valuation allowance has been recorded against certain deferred tax assets related to these carryforwards to the extent management concluded that realization is not more likely than not.

Unrecognized Tax Benefits

The following table summarizes our liability for uncertain tax positions for the fiscal year ended June 30, 2026:

At June 30, 2026, we had $150,000 of gross unrecognized tax benefits related to federal R&D credit which was recorded as a reduction to deferred tax assets, and a corresponding reduction in our valuation allowance of $150,000. At June 30, 2026 there was a payable of $50,000 related to state income tax liability and accrued interest and penalties. The state income tax payable balance decreased by $112,000 from the prior year due to expiration of state statute of limitation periods. There was a deferred tax asset reversal of $2,587,000 due to the reduction of historical California R&D credits. There was a full valuation allowance on the $2,587,000 deferred tax asset, so no provision impact. To the extent such portion of unrecognized tax benefits is recognized at a time such valuation allowance no longer exists, the recognition would reduce the effective tax rate. Our continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. During the fiscal years ended June 30, 2026 and 2025, we recorded an immaterial expense for interest and penalties related to income tax matters in the provision for income taxes. At June 30, 2026, we had approximately $14,000 of accrued interest and penalties related to uncertain tax positions.

At June 30, 2026, our fiscal years ended June 30, 2023 through 2025 remain open to examination by the federal taxing jurisdiction and our fiscal years ended June 30, 2022 through 2025 remain open to examination by the state taxing jurisdictions. However, we have NOLs beginning in the fiscal year ended June 30, 2007 which would cause the statute of limitations to remain open for the year in which the NOL was incurred. Our fiscal years ended June 30, 2018 through 2025 remain open to examination by foreign taxing authorities.

Cash Taxes Paid

We adopted ASU 2023-09 on a prospective basis for the year ended June 30, 2026 and have included the following table as a result of our adoptions, which presents income taxes paid (net of refunds received) for the year ended June 30, 2026:

In general, our leases include office buildings for various facilities worldwide which are all classified as operating leases. We also have financing leases related to some office equipment in the U.S.

The following presents components of lease expense and supplemental cash flow information:

As of June 30, 2026 and 2025, the weighted average discount rate for leases was 4.9% and 4.8%, respectively, and the weighted average remaining lease term for leases was 2.9 years.

Maturities of lease liabilities as of June 30, 2026 were as follows:

From time to time, we are subject to legal proceedings and claims in the ordinary course of business. We are currently not aware of any such legal proceedings or claims that we believe will have, individually or in the aggregate, a material adverse effect on our business, prospects, financial position, operating results or cash flows. We maintain insurance policies for settlements and judgments, as well as legal defense costs, although the amount of insurance coverage that we maintain may not be adequate to cover all claims or liabilities that may arise. In addition, provisions of the Company’s Certificate of Incorporation, Bylaws and indemnification agreements entered into with current and former directors and officers require us, among other things, to indemnify these directors and officers against certain liabilities that may arise by reason of their status or service as directors or officers and to advance expenses to such directors or officers in connection therewith.

Long-lived assets, which consists of property and equipment, net, lease right-of-use assets, intangible assets, net, and goodwill by geographic area are as follows:

Customers

The following table presents sales to our significant customers as a percentage of net revenue:

The following table shows customers that had an outstanding receivable balance that represented at least 10% of our total net accounts receivable:

Related Party Transactions

We hadno net revenue from related parties for the fiscal years ended June 30, 2026 and 2025.

Suppliers

We do not own or operate a manufacturing facility. All of our products are manufactured by third-party contract manufacturers and foundries primarily located in Thailand and Taiwan. We have several single-sourced supplier relationships, either because alternative sources are not available or because the relationship is advantageous to us. If these suppliers are unable to provide a timely and reliable supply of components, we could experience manufacturing delays that could adversely affect our consolidated results of operations.

12. Subsequent Events

Acquisition of Vecima Networks’ Industrial IoT Business

On July 7, 2026, we entered into an asset purchase agreement to acquire the industrial IoT business of Vecima Networks Inc., including its Nero Global Tracking software-as-a-service platform, for aggregate consideration of approximately $11.7 million, excluding working capital adjustments and other customary purchase price adjustments. The acquired business provides GPS-based fleet and asset tracking solutions and serves customers across the fleet, municipal, restoration and industrial asset-tracking markets in North America. We closed the transaction on August 1, 2026.

Since the transaction closed after the fiscal year ended on June 30, 2026, we have not recorded any amounts in the accompanying consolidated financial statements. We are in the process of evaluating the acquisition and, therefore, determining the preliminary allocation of the purchase price, including the identification and valuation of acquired intangible assets and any associated goodwill. Additional disclosures required byASC 805, Business Combinations, will be provided for the quarter ending September 30, 2026 following the completion of the preliminary purchase accounting assessment.
