SEMILEDS CORPORATION AND SUBSIDIARIES

Notes to Unaudited Condensed Consolidated Financial Statements

1. Business

SemiLEDs Corporation (“SemiLEDs” or the “parent company”) was incorporated in Delaware on January 4, 2005 and is a holding company for various wholly owned subsidiaries. SemiLEDs and its subsidiaries (collectively, the “Company”) develop, manufacture and sell high performance light emitting diodes (“LEDs”). The Company’s core products are LED components, LED modules and systems, as well as LED chips and lighting products. LED components, modules and systems have become the most important part of its business. A portion of the Company’s business consists of the sale of contract manufactured LED products. The Company’s customers are concentrated in a few select markets, including India, Japan, the United States and the Netherlands.

As of February 28, 2026, SemiLEDs had one wholly owned operating subsidiary, Taiwan Bandaoti Zhaoming Co., Ltd., which conducts its research, development, manufacturing, marketing and sale of LED components and employs the Company’s employees.

SemiLEDs’ common stock trades on the NASDAQ Capital Market under the symbol “LEDS”.

2. Summary of Significant Accounting Policies

Basis of Presentation —The Company’s unaudited interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable provisions of the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the rules and regulations of the SEC. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on November 28, 2025. The unaudited condensed consolidated balance sheet as of August 31, 2025 included herein was derived from the audited consolidated financial statements as of that date.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the Company’s unaudited condensed consolidated balance sheet as of February 28, 2026, the unaudited condensed statements of operations and comprehensive loss for the three and six months ended February 28, 2026 and 2025, the unaudited condensed statement of changes in equity for the three and six months ended February 28, 2026 and 2025, and the unaudited condensed statements of cash flows for the six months ended February 28, 2026 and 2025. The results for the three or six months ended February 28, 2026 are not necessarily indicative of the results to be expected for the year ending August 31, 2026.

Going Concern —The accompanying unaudited interim condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably, to generate cash flows from operations, and to pursue financing arrangements to support its working capital requirements.

6

The Company suffered losses from operations of $1.6 million and $2.9 million, and net cash provided by operating activities of $2.2 million and net cash used in operating activities of $361 thousand, for the years ended August 31, 2025 and 2024, respectively. These facts and conditions have raised substantial doubt about the Company’s ability to continue as a going concern, even though gross profit on product sales was $2.4 million for the year ended August 31, 2025 compared to $1.1 million for the year ended August 31, 2024. On February 28, 2026, the Company’s cash and cash equivalents had increased to $4.0 million compared to $2.4 million on February 28, 2025. Further, loss from operations was $845 thousand and $1.9 million for the three and six months ended February 28, 2026, respectively. Management believes that it has developed a liquidity plan, as summarized below, that, if executed successfully, should provide sufficient liquidity to meet the Company’s obligations as they become due for a reasonable period of time, and allow the development of its core business. The plan includes:

•Gaining positive cash-inflow from operating activities through continuous cost reductions and the sales of new higher margin products. Steady growth of module products and the continued commercial sales of its UV LED product are expected to improve the Company’s future gross margin, operating results and cash flows. The Company is targeting niche markets and focusing on product enhancement and developing its LED products into many other applications or devices.

•Continuing to monitor prices, work with current and potential vendors to decrease costs and, consistent with its existing contractual commitments, possibly decrease its activity level and capital expenditures further. This plan reflects its strategy of controlling capital costs and maintaining financial flexibility.

•Raising additional cash through potential equity offerings, sales of assets and/or issuance of debt as considered necessary and looking at other potential business opportunities.

While the Company's management believes that the measures described in the above liquidity plan will be adequate to satisfy its liquidity requirements for the twelve months after the date that the financial statements are issued, there is no assurance that the liquidity plan will be successfully implemented. Failure to successfully implement the liquidity plan may have a material adverse effect on its business, results of operations and financial position, and may adversely affect its ability to continue as a going concern. These unaudited interim condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Restricted Cash —Restricted cash primarily consists of cash held in reserved bank accounts in Taiwan, including compensating balances required under the Company's long-term loan requirements. As of February 28, 2026 and August 31, 2025, the Company’s restricted cash at noncurrent portion, which was recorded as other assets, amounted to $173 thousand and $177 thousand, respectively.

Revenue Recognition —Effective September 1, 2018, the Company adopted ASC 606 using the modified retrospective transition method. The Company applied the following five steps to achieve the core principles of ASC 606: 1) identified the contract with a customer; 2) identified the performance obligations (promises) in the contract; 3) determined the transaction price; 4) allocated the transaction price to the performance obligations in the contract; and 5) recognized revenue when (or as) the Company satisfies a performance obligation.

The Company recognizes the amount of revenue, when the Company satisfies a performance obligation, to which it expects to be entitled for the transfer of promised goods or services to customers. The Company obtains written purchase authorizations from its customers as evidence of an arrangement and these authorizations generally provide for a specified amount of product at a fixed price. Generally, the Company considers delivery to have occurred at the time of shipment as this is generally when title and risk of loss for the products will pass to the customer. The Company provides its customers with limited rights of return for non‑conforming shipments and product warranty claims. Based on historical return percentages, which have not been material to date, and other relevant factors, the Company estimates its potential future exposure on recorded product sales, which reduces product revenues in the consolidated statements of operations and reduces accounts receivable in the consolidated balance sheets. The Company also provides standard product warranties on its products, which generally range from three months to two years. Management estimates the Company’s warranty obligations as a percentage of revenues, based on historical knowledge of warranty costs and other relevant factors. To date, the related estimated warranty provisions have been insignificant.

Gross Versus Net Revenue —ASC 606 provides guidance on proper recognition of principal versus agent considerations which are used to determine gross versus net revenue recognition. Under ASC 606, the core objective of the guidance on gross versus net revenue recognition is to help determine whether an entity is a principal or an agent in a transaction. In general, the primary difference between these two is the performance obligation being satisfied. The principal has a performance obligation to provide the desired goods or services to the end customer, whereas the agent arranges for the principal to provide the desired goods or services. Additionally, a fundamental characteristic of a principal in a transaction is control. A principal substantively controls the goods and services before they are transferred to the customer as well as controls the price of the good or service being provided. An agent normally receives a

7

commission or fee for these activities. In addition to control, the level at which an entity controls the price of the good or service being transferred determines principal versus agent status. The more discretion over setting price a company has in providing the good or service, the more likely they are considered a principal rather than an agent. Under the guidance when another party is involved in providing a good or service to a customer, an entity is a principal if the entity obtains control of the asset or right to a service performed by the other party.

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment.

Under buy-sell purchase orders, the Company purchases certain machinery and equipment (the “Goods”) from vendors and sells them to customers. Control of the Goods, including title and risk of loss, transfers to customers upon delivery at their designated seaport, and the Company has discretion in establishing prices. Accordingly, revenue from these transactions is recognized at the gross sales price.

Principles of Consolidation —The unaudited interim condensed consolidated financial statements include the accounts of SemiLEDs and its consolidated subsidiaries. All intercompany transactions and balances have been eliminated during consolidation.

On September 1, 2018, the Company adopted ASC 825-10, “Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. This standard allows equity investments that do not have readily determinable fair values to be re-measured at fair value either upon the occurrence of an observable price change or upon identification of impairment. The standard also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period.

Investments in which the Company has the ability to exercise significant influence over the investee but not a controlling financial interest, are accounted for using the equity method of accounting and are not consolidated. These investments are in joint ventures that are not subject to consolidation under the variable interest model, and for which the Company: (i) does not have a majority voting interest that would allow it to control the investee, or (ii) has a majority voting interest but for which other shareholders have significant participating rights, but for which the Company has the ability to exercise significant influence over operating and financial policies. Under the equity method, investments are stated at cost after adding or removing the Company’s portion of equity in undistributed earnings or losses, respectively. The Company’s investment in these equity‑method entities is reported in the consolidated balance sheets in investments in unconsolidated entities, and the Company’s share of the income or loss of these equity‑method entities, after the elimination of unrealized intercompany profits, is reported in the consolidated statements of operations in equity in losses from unconsolidated entities. When net losses from an equity‑method investee exceed its carrying amount, the carrying amount of the investment is reduced to zero. The Company then suspends using the equity method to provide for additional losses unless the Company has guaranteed obligations or is otherwise committed to provide further financial support to the equity‑method investee. The Company resumes accounting for the investment under the equity method if the investee subsequently returns to profitability and the Company’s share of the investee’s income exceeds its share of the cumulative losses that have not been previously recognized during the period the equity method is suspended.

Investments in entities that are not consolidated or accounted for under the equity method are recorded as investments without readily determinable fair values. Investments without readily determinable fair values are reported on the consolidated balance sheets in investments in unconsolidated entities, at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Dividend income, if any, received is reported in the consolidated statements of operations in equity in losses from unconsolidated entities.

If the fair value of an equity investment declines below its respective carrying amount and the decline is determined to be other‑than‑temporary, the investment will be written down to its fair value.

Use of Estimates —The preparation of unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the preparation of the Company’s consolidated financial statements on the basis that the Company will continue as a going concern, the collectability of accounts receivable, inventory net realizable values, realization of deferred tax assets, valuation of stock-based compensation expense, the useful lives of property, plant and equipment and intangible assets, the recoverability of the carrying amount of property, plant and equipment, intangible assets and investments in unconsolidated entities, the fair value of acquired tangible and intangible assets, income tax uncertainties, provision for potential litigation costs and other contingencies. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Management assesses these estimates on a regular basis; however, actual results could differ materially from those estimates.

Certain Significant Risks and Uncertainties —The Company is subject to certain risks and uncertainties that could have a material and adverse effect on the Company’s future financial position or results of operations, which risks and uncertainties include, among others: it has incurred significant losses over the past several years, any inability of the Company to compete in a rapidly evolving market and to respond quickly and effectively to changing market requirements, any inability of the Company to grow its revenue and/or maintain or increase its margins, it may experience fluctuations in its revenues and operating results, any inability of the Company to protect its intellectual property rights, claims by others that the Company infringes their proprietary technology, and any inability of the Company to raise additional funds in the future.

Concentration of Supply Risk —Some of the components and technologies used in the Company’s products are purchased and licensed from a limited number of sources and some of the Company’s products are produced by a limited number of contract manufacturers. The loss of any of these suppliers and contract manufacturers may cause the Company to incur transition costs to another supplier or contract manufacturer, result in delays in the manufacturing and delivery of the Company’s products, or cause it to carry excess or obsolete inventory. The Company relies on a limited number of such suppliers and contract manufacturers for the fulfillment of its customer orders. Any failure of such suppliers and contract manufacturers to perform could have an adverse effect upon the Company’s reputation and its ability to distribute its products or satisfy customers’ orders, which could adversely affect the Company’s business, financial position, results of operations and cash flows.

Concentration of Credit Risk —Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable.

The Company keeps its cash and cash equivalents in demand deposits with prominent banks of high credit quality and invests only in money market funds. Cash accounts at each institution are insured by the Federal Deposit Insurance Corporation in the United States or Central Deposit Insurance Corporation in Taiwan up to certain limits. At times, such deposits may be in excess of the insurance limit. U.S. accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. As of February 28, 2026 and August 31, 2025, the Company had no cash in excess of FDIC insured limits. The Company maintains cash in state-owned banks in Taiwan, where the insurance coverage of each bank is NTD$3,000,000 (approximately $96,077). As of February 28, 2026 and August 31, 2025, the Company had $3,500 thousand and $2,281 thousand cash in excess of the insured amount, respectively. The Company has not experienced any losses in such accounts. As of February 28, 2026 and August 31, 2025, cash and cash equivalents of the Company consisted of the following (in thousands):

	February 28,		August 31,
Cash and Cash Equivalents by Location	2026		2025
United States;
Denominated in U.S. dollars	$	187	$	187

Denominated in other currencies		139		131
Total cash and cash equivalents	$	3,978	$	2,593

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment. Net revenues generated from buy-sell purchase orders of equipment represented 36% of the Company's revenues for the six months ended February 28, 2026. A significant portion of the Company’s revenues are derived from a limited number of customers, and sales are concentrated in a few select markets. Management performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. Management evaluates the need to establish an allowance for doubtful accounts for

9

estimated potential credit losses at each reporting period. The allowance for doubtful accounts is based on the management’s assessment of the collectability of its customer accounts. Management regularly reviews the allowance by considering certain factors, such as historical experience, industry data, credit quality, ages of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

Net revenues generated from sales to the top ten customers represented 89% and 91% of the Company’s total net revenues for the three and six months ended February 28, 2026, respectively, and 99% and 98% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

The Company’s revenues have been concentrated in a few select markets, including India, Japan, the United States and the Netherlands. Net revenues generated from sales to customers in these markets, in the aggregate, accounted for 69% and 86% of the Company’s net revenues for the three and six months ended February 28, 2026, respectively, and 98% and 97% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

Noncontrolling Interests —Noncontrolling interests are classified in the consolidated statements of operations as part of consolidated net income (loss) and the accumulated amount of noncontrolling interests in the consolidated balance sheets as part of equity. Changes in ownership interest in a consolidated subsidiary that do not result in a loss of control are accounted for as an equity transaction. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are remeasured with the gain or loss reported in net earnings.

On September 1, 2018, Taiwan Bandaoti Zhaoming Co., Ltd., formerly known as Silicon Base Development, Inc. (“SBDI”), the Company’s wholly owned operating subsidiary, issued 414,000 common shares and amended its certificate of incorporation to increase its common stock issued from 12,087,715 shares to 12,501,715 shares. As of the issuance date, the increased capital of $176 thousand (NT$5.4 million) had been completely received in cash by SBDI. SemiLEDs Optoelectronics Co., Ltd. (“Taiwan SemiLEDs”) did not subscribe for the newly issued common shares, and, as a result, the noncontrolling interest in Taiwan SemiLEDs increased from zero to 3.31%. From January 2019 to September 2020, Taiwan SemiLEDs purchased an additional 33,000 common shares of SBDI from non-controlling shareholders. From March 2022 to May 2022, Taiwan SemiLEDs purchased an additional 52,000 common shares of SBDI from non-controlling shareholders. On September 1, 2024, Taiwan SemiLEDs purchased the remaining 329,000 common shares of SBDI from non-controlling shareholders. On April 1, 2025, Taiwan Bandaoti Zhaoming Co., Ltd. merged with and into Taiwan SemiLEDs. Taiwan Bandaoti Zhaoming Co., Ltd. now functions as a division of Taiwan SemiLEDs with all property, obligations, and capital being transferred to Taiwan SemiLEDs. Taiwan SemiLEDs changed its company name to Taiwan Bandaoti Zhaoming Co., Ltd. after the merger. The noncontrolling interest in former Taiwan Bandaoti Zhaoming Co., Ltd. was zero as of February 28, 2026 and August 31, 2025.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in ASU 2023-07 improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (CODM). In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. ASU 2023-07 became effective for annual reporting periods beginning after December 15, 2023, and interim periods within annual reporting periods beginning after December 15, 2024. The Company adopted the ASU on a retrospective basis for all prior periods presented, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The new standard requires entities to disclose additional information about certain expenses, such as purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses included in commonly presented expense captions on the income statement. The FASB further clarified the effective date in January 2025 with the issuance of ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Companies have the option to apply this guidance either on a retrospective or prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of ASU 2024-03 on its unaudited condensed consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”. ASU 2025-05 provides a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods and should be applied prospectively. Early

10

adoption is permitted. The Company adopted the ASU, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”). ASU 2025-06 updates the accounting guidance for internal-use software by eliminating references to software development project stages, thereby requiring companies to start capitalizing software costs when (i) management has authorized and committed to funding the project and (ii) it is probable the project will be completed and the software will be used as intended. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, with early adoption permitted. Amendments can be applied either (i) prospectively, (ii) through a modified transition approach based on the status projects and whether software costs were capitalized before the date of adoption, or (iii) retrospectively. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10 to provide specific authoritative guidance about the recognition, measurement, and presentation of a grant received by a business entity from a government. The amendments in this guidance require that a government grant received by a business entity should not be recognized until (1) it is probable that a business entity will comply with the conditions attached to the grant and the grant will be received and (2) a business entity meets the recognition guidance for a grant related to an asset or a grant related to income. Adoption of this standard is required using either a modified prospective, modified retrospective, or a retrospective approach. This standard is effective for the Company for both interim and annual reporting for the year ended December 31, 2029. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

The Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the unaudited condensed consolidated financial position, statements of operations and cash flows.

Equity Investments without Readily Determinable Fair Value

Equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the Company) which do not have readily determinable fair values are recorded as equity investment without readily determinable fair value.

12

All equity investments without readily determinable fair value are assessed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable, and measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuers. The recoverable value of the investment was determined based on the Company’s best estimate of the amount that could be realized from the investment, which considered the latest financial information. The impairment losses for the equity investments without readily determinable fair value were zero for the three and six months ended February 28, 2026 and 2025.

Equity Method Investments

In July 2023, Taiwan Bandaoti Zhaoming Co., Ltd, the Company’s subsidiary, had a board resolution to hold an equity interest in Yi Yang Optoelectronics Co., Ltd., accounting for its equity interest using the equity method to accounts for its equity investment as prescribed in ASC 323, Investments—Equity Method and Joint Ventures (“ASC 323”). Equity method adjustments include the Company’s proportionate share of investee’s income or loss and other adjustments required by the equity method. The Company owned 47.62% of the common shares of Yi Yang Optoelectronics Co., Ltd. as of both February 28, 2026 and August 31, 2025.

5. Commitments and Contingencies

Operating Lease Agreements —The Company has several operating leases with third parties, primarily for land, plant and office spaces in Taiwan, including cancelable and noncancelable leases that expire at various dates between August 2026 and December 2040. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. For lease agreements entered into or reassessed after the adoption of Topic 842, the Company did not combine lease and non-lease components.

Most leases do not include options to renew. The exercise of lease renewal options has to be agreed by the lessors. The depreciable life of assets and leasehold improvements are limited by the term of leases, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease expense is recognized on a straight-line basis over the term of the lease. Lease expense related to these noncancelable operating leases was $41 thousand and $96 thousand for three months and six months ended February 28, 2026, respectively. Lease expense related to these noncancelable operating leases was $34 thousand and $72 thousand for three months and six months ended February 28, 2025, respectively.

Purchase Obligations —The Company had purchase commitments for inventory, property, plant and equipment in the amount of $5.6 million and $461 thousand as of February 28, 2026 and August 31, 2025, respectively.

Litigation —The Company is directly or indirectly involved from time to time in various claims or legal proceedings arising in the ordinary course of business. The Company recognizes a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. There is significant judgment required in assessing both the likelihood of an unfavorable outcome and whether the amount of loss, if any, can be reasonably estimated.

As of February 28, 2026, there was no pending or threatened litigation that could have a material impact on the Company’s financial position, results of operations or cash flows.

6. Stock-based Compensation

The Company currently has one equity incentive plan (the “2010 Plan”), which provides for awards in the form of restricted shares, stock units, stock options or stock appreciation rights to the Company’s employees, officers, directors and consultants. In April 2014, SemiLEDs’ stockholders approved an amendment to the 2010 Plan that increases the number of shares authorized for issuance under the plan by an additional 250 thousand shares. On July 31, 2019, the stockholders approved an increase in the authorized share reserve under the 2010 plan by an additional 500 thousand shares, to extend expiration of the 2010 Plan to November 3, 2023, to remove the IRS Code section 162(m) provisions, and to modify the maximum grant limit to 35 thousand shares to one person in a one year period. On September 25, 2020, the stockholders approved an amendment to the 2010 Equity Incentive Plan to increase the authorized shares reserve by an additional 400 thousand shares. On March 17, 2023, the Board approved the amendment of the 2010 Plan to extend the term to March 17, 2033, which was approved by the Company's stockholders at the annual meeting held on May 18, 2023.

14

A total of 1,421 thousand and 1,421 thousand shares was reserved for issuance under the 2010 Plan as of February 28, 2026 and 2025, respectively. As of February 28, 2026 and 2025, there were 429 thousand and 530 thousand shares of common stock available for future issuance under the equity incentive plans, respectively.

In November 2025, SemiLEDs granted 15 thousand restricted stock units to its directors, which vest 25% every three months from the vesting commencement date of November 27, 2025 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $2.406 per unit.

In July 2025, SemiLEDs granted 96 thousand restricted stock units to its employees, which vest 12.5% every three months from the vesting commencement date of July 10, 2025 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $2.81 per unit.

In November 2024, SemiLEDs granted 15 thousand restricted stock units to its directors, which vest 25% every three months from the vesting commencement date of November 27, 2024 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $1.28 per unit.

The grant date fair value of stock options is determined using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs including the market price of SemiLEDs’ common stock on the date of grant, the term that the stock options are expected to be outstanding, the implied stock volatilities of several of the Company’s publicly-traded peers over the expected term of stock options, risk-free interest rate and expected dividend. Each of these inputs is subjective and generally requires significant judgment to determine. The grant date fair value of stock units is based upon the market price of SemiLEDs’ common stock on the date of the grant. This fair value is amortized to compensation expense over the vesting term. During the three and six months ended February 28, 2026 and 2025, the Company had no options granted, forfeited, or exercised. As of February 28, 2026 and 2025, the Company had no unvested stock options and the unrecognized compensation costs related to unvested stock options were nil.

Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. A forfeiture rate of zero is estimated for stock-based awards with vesting term that is less than or equal to one year from the date of grant.

A summary of the stock-based compensation expense for the three and six months ended February 28, 2026 and 2025 was as follows (in thousands):

	Three Months Ended				Six Months Ended
	February 28, 2026		February 28, 2025		February 28, 2026		February 28, 2025
Cost of revenues	$	12	$	8	$	24	$	16
Research and development		11		8		23		16

	$	42	$	35	$	81	$	60

7. Net Loss Per Share of Common Stock

The following stock‑based compensation plan awards were excluded from the computation of diluted net loss per share of common stock for the periods presented because including them would have an antidilutive effect on the net loss per share (in thousands of shares):

	Three Months Ended				Six Months Ended
	February 28, 2026		February 28, 2025		February 28, 2026		February 28, 2025

Unrecognized Tax Benefits

On December 22, 2017, the U.S. Tax Cuts and Jobs Act was adopted, which among other effects, reduced the U.S. federal corporate income tax rate to 21% from 34% (or 35% in certain cases) beginning in 2018, requires companies to pay a one-time transition tax on certain unrepatriated earnings from non-U.S. subsidiaries that is payable over eight years, makes the receipt of future non-U.S. sourced income of non-U.S. subsidiaries tax-free to U.S. companies and creates a new minimum tax on the earnings of non-U.S. subsidiaries relating to the parent’s deductions for payments to the subsidiaries. Our provisional estimate is that no tax will be due under this provision.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The provisions of the legislation that were effective for fiscal 2026 did not have a material impact on the Company's income tax expense for the three and six months ended February 28, 2026 and 2025. The Company is currently assessing the impact of the provisions of the OBBBA that are effective in future years on its future consolidated financial statements.

As of both February 28, 2026 and August 31, 2025, the Company had no unrecognized tax benefits related to tax positions taken in prior periods. The Company files income tax returns in the United States, various U.S. states and certain foreign jurisdictions. The tax years 2020 through 2024 remain open in most jurisdictions. With few exceptions, as of February 28, 2026, the Company is no longer subject to U.S. federal, state, local, or foreign examinations by tax authorities for tax years before 2020.

9. Related Party Transactions

On January 8, 2019, the Company entered into secured loan agreements with Trung Doan, its Chairman and Chief Executive Officer and J.R. Simplot Company, its largest shareholder, with aggregate amounts of $1.7 million and $1.5 million, respectively, and an annual interest rate of 8% (the “Loan Agreements”). The Loan Agreements are secured by a second priority security interest on the Company’s headquarters building. The maturity date of the Loan Agreements were January 14, 2021 and January 22, 2021, respectively.

The following discussion and analysis of our financial condition and results of operations is based upon and should be read in conjunction with the unaudited interim condensed consolidated financial statements and the notes and other information included elsewhere in this Quarterly Report, in our 2025 Annual Report, and in other filings with the SEC.

Company Overview

We develop, manufacture and sell light emitting diode (LED) chips and LED components, LED modules and systems. Our products are used for general lighting and specialty industrial applications, including ultraviolet, or UV, curing of polymers, LED light

19

therapy in medical/cosmetic applications, counterfeit detection, germicidal and viricidal devices LED lighting for horticulture applications, architectural lighting and entertainment lighting.

Utilizing our patented and proprietary technology, our manufacturing process begins by growing upon the surface of a sapphire wafer, or substrate, several very thin separate semiconductive crystalline layers of gallium nitride, or GaN, a process known as epitaxial growth, on top of which a mirror‑like reflective silver layer is then deposited. After the subsequent addition of a copper alloy layer and finally the removal of the sapphire substrate, we further process this multiple‑layered material to create individual vertical LED chips.

We package our LED chips into LED components, which we sell to distributors and a customer base that is heavily concentrated in a few select markets, including India, Japan, the United States and the Netherlands. We also sell our “Enhanced Vertical,” or EV, LED product series in blue, white, green and UV in selected markets. We sell our LED chips to packagers or to distributors, who in turn sell to packagers. Our lighting products customers are primarily original design manufacturers, or ODMs, of lighting products and the end‑users of lighting devices. We also contract other manufacturers to produce for our sale certain LED products, and for certain aspects of our product fabrication, assembly and packaging processes, based on our design and technology requirements and under our quality control specifications and final inspection process. In addition, beginning in fiscal year 2025, we have entered into number buy-sell orders for equipment that we purchased and then sold to our customer.

We have developed advanced capabilities and proprietary know-how in:

•reusing sapphire substrate in subsequent production runs;

•optimizing our epitaxial growth processes to create layers that efficiently convert electrical current into light;

•employing a copper alloy base manufacturing technology to improve our chip’s thermal and electrical performance;

•utilizing nanoscale surface engineering to improve usable light extraction;

•manufacturing extremely small footprint LEDs with optimized yield, ideal for Mini LED applications;

•developing a LED structure that generally consists of multiple epitaxial layers which are vertically-stacked on top of a copper alloy base;

•developing low cost Chip Scaled Packaging (CSP) technology;

•developing multi-pixel Mini LED packages for commercial displays; and

•developing small format AI sensors having a light source and photodetector in cooperation with our Japanese partners for various applications such as dot projectors and photoplethysmogram (PPG) sensors.

These technical capabilities enable us to produce LED chips, LED components, LED modules and System products. We believe these capabilities and know-how should also allow us to reduce our manufacturing costs and our dependence on sapphire, a costly raw material used in the production of sapphire-based LED devices.

We were incorporated in the State of Delaware on January 4, 2005. We are a holding company for our wholly owned operating subsidiary, Taiwan Bandaoti Zhaoming Co., Ltd., which conducts our research, development, manufacturing, marketing and sale of LED components and employs the Company’s employees.

Recent Development

In the first quarter of fiscal 2026, we entered into buy-sell purchase orders pursuant to which we purchased equipment and then resold the goods to our customer. The revenue relating to these purchase orders was $1.3 million in the first quarter of fiscal 2026, and the associated cost of revenue was $1.2 million. We did not have any buy-sell purchase orders during the second quarter of fiscal 2026.

We anticipate buy-sell purchase orders in the third quarter of fiscal 2026. As a result of these purchase orders and associated uncertainty of the business, our revenue, cost of revenues, receivables, inventories and customer deposits over future quarters may vary significantly. In addition, if our shipments are delayed, revenue recognition may be delayed into future quarters. We cannot assure you when, or if, the revenue will be recognized, when payments will be received, or if we will receive further orders in the future.

Key Factors Affecting Our Financial Condition, Results of Operations and Business

The following are key factors that we believe affect our financial condition, results of operations and business:

•Our ability to continue or grow with buy-sell revenue. Our recent reliance on buy-sell purchase orders of equipment has improved our gross profit, operating results and cash flows. We anticipate our buy-sell purchase orders will fluctuate from

20

period to period. However, if orders diminish or cease altogether, our gross margin, operating results, and cash flows could be adversely affected.

•Our ability to raise additional debt funding, sell additional equity securities and improve our liquidity. We need to improve our liquidity, access alternative sources of funding and obtain additional equity capital or debt when necessary for our operations. However, we may not be able to obtain such debt funding or sell equity securities on terms that are favorable to us, or at all. The raising of additional debt funding by us, if required and available, would result in increased debt service obligations and could result in additional operating and financing covenants, or liens on our assets, that would restrict our operations. The sale of additional equity securities, if required and available, could result in dilution to our stockholders.

•Our ability to source chips from other chip suppliers. Our reliance on our chip suppliers exposes us to a number of significant risks, including reduced control over delivery schedules, quality assurance and production costs, lack of guaranteed production capacity or product supply. If our chip suppliers are unable or unwilling to continue to supply our chips at requested quality, quantity, performance and costs, or in a timely manner, our business and reputation could be seriously harmed. Our inability to procure chips from other chip suppliers at the desired quality, quantity, performance and cost might result in unforeseen manufacturing and operations problems. In such events, our customer relationships, business, financial condition and results of operations would be adversely affected.

•Industry growth and demand for products and applications using LEDs. The overall adoption of LED lighting devices to replace traditional lighting sources is expected to influence the growth and demand for LED chips and component products and impact our financial performance. We believe the potential market for LED lighting will continue to expand. LEDs for efficient generation of UV light are also starting to gain attention for various medical, germicidal and industrial applications. Since a substantial portion of our LED chips, LED components and our lighting products are used by end‑users in general lighting applications and specialty industrial applications such as UV curing, medical/cosmetic, counterfeit detection, horticulture, architectural lighting and entertainment lighting the adoption of LEDs into these applications will have a strong impact on the demand of LED chips generally and, as a result, for our LED chips, LED components and LED lighting products.

•Average selling price of our products. The average selling price of our products may decline for a variety of factors, including prices charged by our competitors, the efficacy of our products, our cost basis, changes in our product mix, the size of the order and our relationship with the relevant customer, as well as general market and economic conditions. Competition in the markets for LED products is intense, and we expect that competition will continue to increase, thereby creating a highly aggressive pricing environment. For example, some of our competitors have in the past reduced their average selling prices, and the resulting competitive pricing pressures have caused us to similarly reduce our prices, accelerating the decline in our revenues and the gross margin of our products. When prices decline, we must also write down the value of our inventory. Furthermore, the average selling prices for our LED products have typically decreased over product life cycles. Therefore, our ability to continue to innovate and offer competitive products that meet our customers’ specifications and pricing requirements, such as higher efficacy LED products at lower costs, will have a material influence on our ability to improve our revenues and product margins, although in the near term the introduction of such higher performance LED products may further reduce the selling prices of our existing products or render them obsolete.

•Changes in our product mix. We anticipate that our gross margins will continue to fluctuate from period to period as a result of the mix of products that we sell and the utilization of our manufacturing capacity in any given period, among other things. For example, we continue to pursue opportunities for profitable growth in areas of business where we see the best opportunity to develop as an end-to-end LED module solution supplier by providing our customers with high quality, flexible and more complete LED system solution, customer technical support and LED module/system design, as opposed to just providing customers with individual components. As a strategic plan, we have placed greater emphasis on the sales of LED components rather than the sales of LED chips where we have been forced to cut prices on older inventory. The growth of our module products and the continued commercial sales of our UV LED product are expected to improve our gross margin, operating results and cash flows. In addition, we have adjusted the lower-priced LED components strategy as appropriate. We have adopted a strategy to adjust our product mix by exiting certain high volume but low unit selling price product lines in response to the general trend of lower average selling prices for products that have been available in the market for some time. However, as we expand and diversify our product offerings and with varying average selling prices, or execute new business initiatives, a change in the mix of products that we sell in any given period may increase volatility in our revenues and gross margin from period to period.

•Our ability to reduce cost to offset lower average selling prices. Competitors may reduce average selling prices faster than our ability to reduce costs, and competitive pricing pressures may accelerate the rate of decline of our average selling prices. To address increased pricing pressure, we have improved and increased our production yields to reduce the per-unit cost of production of our products. However, such cost savings currently have limited impact on our gross profit, as we currently suffer from the underutilization of manufacturing capacity and must absorb a high level of fixed costs, such as depreciation. While we intend to focus on managing our costs and expenses, over the long term we expect to be required to invest substantially in LED components product development and production equipment if we are to grow.

21

•Our ability to continue to innovate. As part of our growth strategy, we plan to continue to be innovative in product design, to deliver new products and to improve our manufacturing efficiencies. Our continued success depends on our ability to develop and introduce new, technologically advanced and lower cost products, such as more efficient, better performance LED components product. If we are unable to introduce new products that are commercially viable and meet rapidly evolving customer requirements or keep pace with evolving technological standards and market developments or are otherwise unable to execute our product innovation strategy effectively, we may not be able to take advantage of market opportunities as they arise, execute our business plan or be able to compete effectively. To differentiate ourselves from other LED package manufacturers, we are putting more resources towards module and system design. Along with our technical know-how in the chip and package sectors, we are able to further integrate electrical, thermal and mechanical manufacturing resources to provide customers with one-stop system services. Services include design, prototyping, OEM and ODM. Key markets that we intend to target at the system end include different types of UV LED industrial printers, aquarium lighting, medical applications, niche imaging light engines, horticultural lighting and high standard commercial lighting. The modules are designed for various printing, curing, and PCB exposure industrial equipment, providing uncompromised reliability and optical output. Our LED components include different sizes and wattage to accommodate different demands in the LED market.

•General economic conditions and geographic concentration. Many countries including the United States and the European Union (the “E.U.”) members have instituted, or have announced plans to institute, government regulations and programs designed to encourage or mandate increased energy efficiency in lighting. These actions include in certain cases banning the sale after specified dates of certain forms of incandescent lighting, which are advancing the adoption of more energy efficient lighting solutions such as LEDs. When the global economy slows or a financial crisis occurs, consumer and government confidence declines, with levels of government grants and subsidies for LED adoption and consumer spending likely to be adversely impacted. Our revenues have been concentrated in a few select markets, including India, Japan, the United States and the Netherlands. Given that we are operating in a rapidly changing industry, our sales in specific markets may fluctuate from quarter to quarter. Therefore, our financial results will be impacted by general economic and political conditions in such markets. For example, the aggressive support by the Chinese government for the LED industry through significant government incentives and subsidies to encourage the use of LED lighting and to establish the LED‑sector companies has resulted in production overcapacity in the market and intense competition. Furthermore, due to Chinese package manufacturers increasing usage of domestic LED chips, prices are increasingly competitive, leading to Chinese manufacturers growing market share in the global LED industry. In addition, we have historically derived a significant portion of our revenues from a limited number of customers. Some of our largest customers and what we produce for them have changed from quarter to quarter primarily as a result of the timing of discrete, large project‑based purchases and broadening customer base, among other things. For the three and six months ended February 28, 2026, sales to our three largest customers, in the aggregate, accounted for 59% of our revenues.

•Intellectual property issues. Competitors of ours and other third parties have in the past and will likely from time to time in the future allege that our products infringe on their intellectual property rights. Defending against any intellectual property infringement claims would likely result in costly litigation and ultimately may lead to our not being able to manufacture, use or sell products found to be infringing. However, other third parties may also assert infringement claims against our customers with respect to our products, or our customers’ products that incorporate our technologies or products. Any such legal action or the threat of legal action against us, or our customers, could impair such customers’ continued demand for our products. This could prevent us from growing or even maintaining our revenues, or cause us to incur additional costs and expenses, and adversely affect our financial condition and results of operations.

•Cash position. Our cash and cash equivalents increased to $4.0 million as of February 28, 2026 from $2.4 million as of February 28, 2025. We have implemented actions to accelerate operating cost reductions and improve operational efficiencies. The plan is further enhanced through the fabless business model in which we implemented certain workforce reductions and are exploring the opportunities to sell certain equipment related to the manufacturing of vertical LED chips, in order to reduce the idle capacity charges and minimize our research and development activities associated with chips manufacturing operation. Based on our current financial projections and assuming our outstanding notes are converted or extended, we believe that we will have sufficient sources of liquidity to fund our operations and capital expenditure plans for the next 12 months.

Critical Accounting Policies and Estimates

We believe that the application of the following accounting policies, which are important to our financial position and results of operations, require significant judgments and estimates on the part of management. For a summary of our significant accounting policies, including the accounting policies discussed below, see Item 1 to the Unaudited Consolidated Financial Statements.

22

Revenue Recognition

The Company recognizes the amount of revenue when the Company satisfies a performance obligation to which it expects to be entitled for the transfer of promised goods or services to customers. The Company obtains written purchase authorizations from its customers as evidence of an arrangement and these authorizations generally provide for a specified amount of product at a fixed price. Generally, the Company considers delivery to have occurred at the time of shipment as this is generally when title and risk of loss for the products will pass to the customer. The Company provides its customers with limited rights of return for non-conforming shipments and product warranty claims. Based on historical return percentages, which have not been material to date, and other relevant factors, the Company estimates its potential future exposure on recorded product sales, which reduces product revenues in the consolidated statements of operations and reduces accounts receivable in the consolidated balance sheets. The Company also provides standard product warranties on its products, which generally range from three months to two years. Management estimates the Company’s warranty obligations as a percentage of revenues, based on historical knowledge of warranty costs and other relevant factors. To date, the related estimated warranty provisions have been insignificant. Refer to Note 2 to the Unaudited Condensed Consolidated Financial Statements for our revenue recognition policies.

Gross Versus Net Revenue

ASC 606 provides guidance on proper recognition of principal versus agent considerations which are used to determine gross versus net revenue recognition. Under ASC 606, the core objective of the guidance on gross versus net revenue recognition is to help determine whether an entity is a principal or an agent in a transaction. In general, the primary difference between these two is the performance obligation being satisfied. The principal has a performance obligation to provide the desired goods or services to the end customer, whereas the agent arranges for the principal to provide the desired goods or services. Additionally, a fundamental characteristic of a principal in a transaction is control. A principal substantively controls the goods and services before they are transferred to the customer as well as controls the price of the good or service being provided. An agent normally receives a commission or fee for these activities. In addition to control, the level at which an entity controls the price of the good or service being transferred determines principal versus agent status. The more discretion over setting price a company has in providing the good or service, the more likely they are considered a principal rather than an agent. Under the guidance when another party is involved in providing a good or service to a customer, an entity is a principal if the entity obtains control of the asset or right to a service performed by the other party.

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment.

Under buy-sell purchase orders, the Company purchases certain machinery and equipment (the “Goods”) from vendors and sells them to customers. Control of the Goods, including title and risk of loss, transfers to customers upon delivery at their designated seaport, and the Company has discretion in establishing prices. Accordingly, revenue from these transactions is recognized at the gross sales price.

Accounts Receivable

The allowance for doubtful accounts is based on management’s assessment of the collectability of customer accounts. Management regularly reviews the allowance by considering certain factors such as historical experience, industry data, credit quality, age of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay. No bad debt expenses were recognized during the three and six months ended February 28, 2026 and 2025.

Write-down of Inventories

The Company writes down excess and obsolete inventory to its estimated net realizable value. The net realized value of inventories is the estimated selling price in the ordinary course of business less the estimated costs of completion and disposal. The estimation of net realized value is based on current market conditions and historical experience with product sales of similar nature. Changes in market conditions may have a material impact on the estimation of the net realizable value. For finished goods and work in process, if the estimated net realizable value for an inventory item, which is the estimated selling price in the ordinary course of business, less reasonably predicable costs to completion and disposal, is lower than its cost, the specific inventory item is written down to its estimated net realizable value. Net realizable value for raw materials is based on replacement cost. Provisions for inventory write downs are included in cost of revenues in the consolidated statements of operations. Once written down, inventories are carried at this lower cost basis until sold or scrapped. Inventory write‑downs to estimated net realizable values were $126 thousand and $50 thousand for the three months ended February 28, 2026 and 2025, respectively.

Exchange Rate Information

We are a Delaware corporation and, under SEC requirements, must report our financial position, results of operations and cash flows in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. At the same time, our subsidiaries use the local currency as their functional currency. For example, the functional currency for Taiwan Bandaoti Zhaoming Co., Ltd. is the NT dollar. The assets and liabilities of the subsidiaries are, therefore, translated into U.S. dollars at exchange rates in effect at each balance sheet date, and income and expense accounts are translated at average exchange rates during the period. The resulting translation adjustments are recorded to a separate component of accumulated other comprehensive income (loss) within equity. Any gains and losses from transactions denominated in currencies other than their functional currencies are recognized in the consolidated statements of operations as a separate component of other income (expense). Due to exchange rate fluctuations, such translated amounts may vary from quarter to quarter even in circumstances where such amounts have not materially changed when denominated in their functional currencies.

The translations from NT dollars to U.S. dollars were made at the exchange rates set forth in the statistical release of the Bank of Taiwan. On February 28, 2026, the exchange rate was 31.23 NT dollars to one U.S. dollar. On April 6, 2026, the exchange rate was 31.52 NT dollars to one U.S. dollar.

No representation is made that the NT dollar or U.S. dollar amounts referred to herein could have been or could be converted into U.S. dollars or NT dollars, as the case may be, at any particular rate or at all.

(1) Other revenues for the three months ended February 28, 2026 primarily include revenues attributable to the sale of epitaxial wafers, scraps and raw materials and the provision of services and a joint development project with CrayoNano AS, and other revenues for the three months ended February 28, 2025 primarily represent revenues attributable to buy-sell purchase orders of equipment.

Revenues, net

Our revenues decreased by 90% from $10.9 million for the three months ended February 28, 2025 to $1.1 million for the three months ended February 28, 2026. The decrease in revenues was driven almost entirely by the $10.0 million decrease in sales of other revenues as a result of the absence of any buy-sell purchase orders of equipment in the three months ended February 28, 2026.

Revenues attributable to the sales of our LED chips were $26 thousand and $29 thousand of our revenues for the three months ended February 28, 2026 and 2025, respectively. The decrease in sales of LED chips was primarily due to varying volumes sold for the LED chips.

Revenues attributable to the sales of our LED components were $423 thousand and $682 thousand for the three months ended February 28, 2026 and 2025, respectively. The decrease in sales of LED components was primarily due to varying volumes sold for the LED components.

Revenues attributable to the sales of our lighting products were $69 thousand and $58 thousand for the three months ended February 28, 2026 and 2025, respectively. The increase in sales of lighting products was primarily due to varying volumes sold for lighting products.

24

Revenues attributable to our other revenues were $546 thousand and $10.1 million of our revenues for the three months ended February 28, 2026 and 2025, respectively. The decrease in other revenues was primarily due to absence of buy-sell purchase orders of equipment in the three months ended February 28, 2026.

Cost of Revenues

Our cost of revenues decreased by 89% from $10 million for the three months ended February 28, 2025 to $1.1 million for the three months ended February 28, 2026. The decrease in cost of revenues was due to the absence of cost of equipment relating to buy-sell purchase orders of equipment.

Gross Profit

Our gross profit represented 1% and 9% of our revenues for the three months ended February 28, 2026 and 2025, respectively. The decrease in gross margin for the three months ended February 28, 2026 was primarily due to the absence of buy-sell purchase orders of equipment.

Our research and development expenses decreased from $279 thousand for the three months ended February 28, 2025 to $276 thousand for the three months ended February 28, 2026. The decrease was primarily due to a $55 thousand increase in payroll expense offset by a $60 thousand decrease in materials and supplies used in research and development.

Selling, general and administrative

Our selling, general and administrative expenses decreased from $614 thousand for the three months ended February 28, 2025 to $575 thousand for the three months ended February 28, 2026. The decrease was mainly attributable to a $37 thousand decrease in shipping expense, a $27 thousand decrease in payroll expense and a $23 thousand decrease in professional service expense, partially offset by a $31 thousand increase in utilities expense and a $31 thousand increase in travel expense.

Investment loss from unconsolidated entities Investment loss from unconsolidated entities decreased from $10 thousand for the three months ended February 28, 2025 to $6 thousand for the three months ended February 28, 2026, primarily due to the increase in the fair value of equity method investments.

Interest expenses, net Interest expenses, net, which primarily consisted of accrued interest payments on loans with our Chairman and Chief Executive Officer and our largest shareholder, decreased from $42 thousand for the three months ended February 28, 2025 to $22 thousand for the three months ended February 28, 2026. The decrease in interest expense, net was primarily due to the repayment of $1.6 million of loan principal in fiscal year 2025.

Other income, net Other income, net increased from $265 thousand for the three months ended February 28, 2025 to $275 thousand for the three months ended February 28, 2026, primarily due to increased rental income.

Foreign currency transaction (loss) gain, net We recognized a net foreign currency transaction loss of $5 thousand and a net foreign currency transaction gain of $65 thousand for the three months ended February 28, 2026 and 2025, respectively, primarily due to the impact of fluctuations in the exchange rate of the U.S. dollar against the NT dollar from bank deposits and accounts receivable.

Income Tax Expense

Our effective tax rate is expected to be approximately zero for both fiscal year 2026 and 2025, since Taiwan Bandaoti Zhaoming Co., Ltd. incurred losses, and because we provided a full valuation allowance on all deferred tax assets, which consisted primarily of net operating loss carryforwards and foreign investment loss.

Gain on disposal of long-lived assets, net

We recognized a net gain of $30 thousand and zero on the disposal of long-lived assets for the six months ended February 28, 2026 and 2025, respectively.

Liquidity and Capital Resources

This section includes a discussion and analysis of our cash requirements, contingencies, sources and uses of cash, operations, working capital and long-term assets and liabilities.

Contingencies

We have several operating leases with third parties, primarily for land, plant and office spaces in Taiwan, including cancellable and noncancelable leases that expire at various dates between August 2026 and December 2040. See Note 5, "Commitments and Contingencies" in the notes to our unaudited consolidated financial statements in this Form 10-Q.

Sources and Uses of Cash

As of February 28, 2026 and August 31, 2025, we had cash and cash equivalents of $4.0 million and $2.6 million, respectively, which were predominately held in U.S. dollar denominated demand deposits and/or money market funds. We require cash to fund our operating expenses, working capital requirements and service our debts, including principal and interest.

As of April 6, 2026, we had no available credit facility.

Long-term assets and liabilities

Our long-term assets consist primarily of property, plant and equipment, intangible assets, operating lease assets and investments in unconsolidated entities. Our manufacturing rationalization plans have included efforts to utilize our existing manufacturing assets and supply arrangements more efficiently. We believe that near-term access to additional manufacturing capacity, should it be required,

28

could be readily obtained on reasonable terms through manufacturing agreements with third parties. We will continue to look for opportunities to make strategic manufacturing in the future for additional capacity.

Our long-term liabilities consist primarily long-term debt and operating lease liabilities.

Our long-term debt, which consisted of NT dollar denominated long-term notes and loans from our Chairman and our largest shareholder, totaled $1.5 million and $1.7 million as of February 28, 2026 and August 31, 2025, respectively.

Our NT dollar denominated long-term notes totaled $658 thousand and $908 thousand as of February 28, 2026 and August 31, 2025, respectively. These long-term notes consist of two loans which we entered into on July 5, 2019, with aggregate amounts of $3.2 million (NT$100 million). The first loan originally for $2.0 million (NT$62 million) has an annual floating interest rate equal to the NTD base lending rate plus 0.64% (or 2.415% currently), and was exclusively used to repay the existing loans. The second loan originally for $1.2 million (NT$38 million) has an annual floating interest rate equal to the NTD base lending rate plus 1.02% (or 2.795% currently) and is available for operating capital. These loans are secured by an $80 thousand (NT$2.5 million) security deposit and a first priority security interest on the Company’s headquarters building.

•Starting from May 2021, the first note payable requires monthly payments of principal in the amount of $25 thousand plus interest over the 74-month term of the note with final payment to occur in July 2027 and, as of February 28, 2026, our outstanding balance on this note payable was approximately $408 thousand.

As of February 28, 2026 and August 31, 2025, these loans totaled $1.2 million and $800 thousand, respectively.

Working Capital

We have incurred significant losses since inception, including net loss attributable to SemiLEDs stockholders of $603 thousand and net income attributable to SemiLEDs stockholders of $388 thousand during the three months ended February 28, 2026 and 2025, respectively. Net cash provided by operating activities for the six months ended February 28, 2026 was $1.6 million. As of February 28, 2026, we had cash and cash equivalents of $4.0 million. We have undertaken actions to decrease losses incurred and implemented cost reduction programs in an effort to transform the Company into a profitable operation. In addition, we are planning to issue additional equity to our stockholders.

We estimate that our cash requirements to service debt and contractual obligations in fiscal 2026 is approximately $2.0 million, which we expect to fund through the issuance of additional equity to repay principal and accrued interest and through loan extensions. Based on our current financial projections and assuming the successful implementation of our liquidity plans, we believe that we will have sufficient sources of liquidity to fund our operations and capital expenditure plans for the next 12 months and beyond. The remaining loans with each of our Chairman and Chief Executive Officer and our largest shareholder are expected to be extended upon maturity or repaid with equity. However, there can be no assurances that our planned activities will be successful in raising additional capital, reducing losses and preserving cash. If we are not able to generate positive cash flows from operations, we may need to consider alternative financing sources and seek additional funds through public or private equity financings or from other sources, or refinance

30

our indebtedness, to support our working capital requirements or for other purposes. There can be no assurance that additional debt or equity financing will be available to us or that, if available, such financing will be available on terms favorable to us.

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial conditions, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to our common stock.

Cash Flows

The following summary of our cash flows for the periods indicated has been derived from our unaudited interim condensed consolidated financial statements, which are included elsewhere in this Quarterly Report (in thousands):

Net cash used in investing activities	$	(16	)	$	(258	)
Net cash used in financing activities	$	(230	)	$	(351	)

Cash Flows Provided by Operating Activities

Net cash provided by operating activities for the six months ended February 28, 2026 and 2025 was $1.6 million and $1.2 million, respectively. The increase in cash flows provided by operating activities was primary attributable to a $9.7 million decrease of inventory, a $1.7 million decrease of accounts receivables, a $192 thousand decrease of prepaid expenses and other current assets and a $132 thousand increase of inventory write downs, partially offset by a $7.2 million decrease of accrued expenses, a $3.1 million decrease of accounts payable and a $1.2 million increase in net loss.

Cash Flows Used in Investing Activities

Net cash used in investing activities for the six months ended February 28, 2026 and 2025 was $16 thousand and $258 thousand, respectively, primarily for the purchases of property, plant and equipment during each period.

Cash Flows Used in Financing Activities

Net cash used in financing activities for the six months ended February 28, 2026 and 2025 was $230 thousand and $351 thousand, respectively. The decrease in cash flows used in financing activities was primarily due to the acquisition of noncontrolling interest of $130 thousand during the six months ended February 28, 2025.

Capital Expenditures

We had capital expenditures of $44 thousand and $238 thousand for the six months ended February 28, 2026 and 2025, respectively. Our capital expenditures consisted primarily of the purchases of machinery and equipment, construction in progress, prepayments for our manufacturing facilities and prepayments for equipment purchases. We expect to continue investing in capital expenditures in the future as we expand our business operations and invest in such expansion of our production capacity as we deem appropriate under market conditions and customer demand. However, in response to controlling capital costs and maintaining financial flexibility, our management continues to monitor prices and, consistent with its existing contractual commitments, may decrease its activity level and capital expenditures as appropriate.

There have been no material changes from the risk factors previously disclosed in Part I, Item 1A, Risk Factors, of our 2025 Annual Report, other than as described below:

We may fail to qualify for continued listing on Nasdaq which could make it more difficult for investors to sell their shares.

Our common stock is listed on the Nasdaq Capital Market. To maintain that listing, we must satisfy the continued listing requirements of Nasdaq for continued listing on the Nasdaq Capital Market, including among other things, a minimum stockholders’ equity of $2.5 million and a minimum bid price for our common stock of $1.00 per share.

On January 30, 2026, we received a notice from Nasdaq indicating that we did not meet the minimum of $2.5 million in stockholders’ equity required by Nasdaq Listing Rule 5550(b)(1) for continued listing or the alternatives of market value of listed securities or net income from continuing operations. Pursuant to the Nasdaq listing rule, we submitted a plan to Nasdaq. Nasdaq accepted our plan, and we were granted an extension of up to 180 calendar days from January 30, 2026 to evidence compliance.

There can be no assurance that we will be able to regain and maintain compliance with Nasdaq’s continued listing requirements or that our common stock will not be delisted from Nasdaq.

If our common stock is delisted by Nasdaq, we expect prices for our common stock to be quoted on one of the OTC Markets or the OTC Bulletin Board. Under such circumstances, stockholders may find it more difficult to sell, or to obtain accurate quotations, for our common stock, and our common stock would become substantially less attractive to certain purchasers such as financial institutions, hedge funds and other similar investors. There is no assurance, however, that prices of our common stock would be quoted on one of these other trading systems or that an active trading market for our common stock would thereafter exist, which would materially and adversely impact the market value of our common stock.

We may be required to delay the recognition of revenues if the shipment of equipment purchased on buy-sell orders is delayed.

In the first quarter of fiscal 2026, we entered into buy-sell purchase orders pursuant to which we purchased equipment and then resold the goods to our customer. The revenue relating to these purchase orders was $1.3 million, and the associated cost of revenue was $1.2 million. We did not have any buy-sell purchase orders during the second quarter of fiscal 2026.

We anticipate buy-sell purchase orders in the third quarter of fiscal 2026. As a result of these purchase orders and associated uncertainty of the business, our revenue, cost of revenues, receivables, inventories and customer deposits over future quarters may vary significantly. In addition, if our shipments are delayed, revenue recognition may be delayed into future quarters. We cannot assure you when, or if, the revenue will be recognized, when payments will be received, or if we will receive further orders in the future.

Trade matters, including tariffs, may impact our ability to compete cost-effectively.

33

Our operations are subject to complex trade and customs laws, regulations, and tax requirements. The countries in which our products are sold may impose duties, tariffs, or other restrictions from time to time on our sales or adversely change existing restrictions. For example, the United States has recently imposed substantial tariffs on goods imported from many countries, including a 15% tariff on goods imported from Taiwan. In fiscal year 2025, 1.6 percent of our products, by dollar value, were sold into the United States. The current political landscape, including with respect to the United States’ foreign policy priorities and relations with trading partners, has introduced greater uncertainty with respect to future tax and trade policy. We are unable to determine the impact that changes in tax and trade policy could have on our sales into the United States or other countries, but it could be material.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation —The Company’s unaudited interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable provisions of the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the rules and regulations of the SEC. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on November 28, 2025. The unaudited condensed consolidated balance sheet as of August 31, 2025 included herein was derived from the audited consolidated financial statements as of that date.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the Company’s unaudited condensed consolidated balance sheet as of February 28, 2026, the unaudited condensed statements of operations and comprehensive loss for the three and six months ended February 28, 2026 and 2025, the unaudited condensed statement of changes in equity for the three and six months ended February 28, 2026 and 2025, and the unaudited condensed statements of cash flows for the six months ended February 28, 2026 and 2025. The results for the three or six months ended February 28, 2026 are not necessarily indicative of the results to be expected for the year ending August 31, 2026.

Going Concern —The accompanying unaudited interim condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably, to generate cash flows from operations, and to pursue financing arrangements to support its working capital requirements.

The Company suffered losses from operations of $1.6 million and $2.9 million, and net cash provided by operating activities of $2.2 million and net cash used in operating activities of $361 thousand, for the years ended August 31, 2025 and 2024, respectively. These facts and conditions have raised substantial doubt about the Company’s ability to continue as a going concern, even though gross profit on product sales was $2.4 million for the year ended August 31, 2025 compared to $1.1 million for the year ended August 31, 2024. On February 28, 2026, the Company’s cash and cash equivalents had increased to $4.0 million compared to $2.4 million on February 28, 2025. Further, loss from operations was $845 thousand and $1.9 million for the three and six months ended February 28, 2026, respectively. Management believes that it has developed a liquidity plan, as summarized below, that, if executed successfully, should provide sufficient liquidity to meet the Company’s obligations as they become due for a reasonable period of time, and allow the development of its core business. The plan includes:

•Gaining positive cash-inflow from operating activities through continuous cost reductions and the sales of new higher margin products. Steady growth of module products and the continued commercial sales of its UV LED product are expected to improve the Company’s future gross margin, operating results and cash flows. The Company is targeting niche markets and focusing on product enhancement and developing its LED products into many other applications or devices.

•Continuing to monitor prices, work with current and potential vendors to decrease costs and, consistent with its existing contractual commitments, possibly decrease its activity level and capital expenditures further. This plan reflects its strategy of controlling capital costs and maintaining financial flexibility.

•Raising additional cash through potential equity offerings, sales of assets and/or issuance of debt as considered necessary and looking at other potential business opportunities.

While the Company's management believes that the measures described in the above liquidity plan will be adequate to satisfy its liquidity requirements for the twelve months after the date that the financial statements are issued, there is no assurance that the liquidity plan will be successfully implemented. Failure to successfully implement the liquidity plan may have a material adverse effect on its business, results of operations and financial position, and may adversely affect its ability to continue as a going concern. These unaudited interim condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Restricted Cash —Restricted cash primarily consists of cash held in reserved bank accounts in Taiwan, including compensating balances required under the Company's long-term loan requirements. As of February 28, 2026 and August 31, 2025, the Company’s restricted cash at noncurrent portion, which was recorded as other assets, amounted to $173 thousand and $177 thousand, respectively.

Revenue Recognition —Effective September 1, 2018, the Company adopted ASC 606 using the modified retrospective transition method. The Company applied the following five steps to achieve the core principles of ASC 606: 1) identified the contract with a customer; 2) identified the performance obligations (promises) in the contract; 3) determined the transaction price; 4) allocated the transaction price to the performance obligations in the contract; and 5) recognized revenue when (or as) the Company satisfies a performance obligation.

The Company recognizes the amount of revenue, when the Company satisfies a performance obligation, to which it expects to be entitled for the transfer of promised goods or services to customers. The Company obtains written purchase authorizations from its customers as evidence of an arrangement and these authorizations generally provide for a specified amount of product at a fixed price. Generally, the Company considers delivery to have occurred at the time of shipment as this is generally when title and risk of loss for the products will pass to the customer. The Company provides its customers with limited rights of return for non‑conforming shipments and product warranty claims. Based on historical return percentages, which have not been material to date, and other relevant factors, the Company estimates its potential future exposure on recorded product sales, which reduces product revenues in the consolidated statements of operations and reduces accounts receivable in the consolidated balance sheets. The Company also provides standard product warranties on its products, which generally range from three months to two years. Management estimates the Company’s warranty obligations as a percentage of revenues, based on historical knowledge of warranty costs and other relevant factors. To date, the related estimated warranty provisions have been insignificant.

Gross Versus Net Revenue —ASC 606 provides guidance on proper recognition of principal versus agent considerations which are used to determine gross versus net revenue recognition. Under ASC 606, the core objective of the guidance on gross versus net revenue recognition is to help determine whether an entity is a principal or an agent in a transaction. In general, the primary difference between these two is the performance obligation being satisfied. The principal has a performance obligation to provide the desired goods or services to the end customer, whereas the agent arranges for the principal to provide the desired goods or services. Additionally, a fundamental characteristic of a principal in a transaction is control. A principal substantively controls the goods and services before they are transferred to the customer as well as controls the price of the good or service being provided. An agent normally receives a

commission or fee for these activities. In addition to control, the level at which an entity controls the price of the good or service being transferred determines principal versus agent status. The more discretion over setting price a company has in providing the good or service, the more likely they are considered a principal rather than an agent. Under the guidance when another party is involved in providing a good or service to a customer, an entity is a principal if the entity obtains control of the asset or right to a service performed by the other party.

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment.

Under buy-sell purchase orders, the Company purchases certain machinery and equipment (the “Goods”) from vendors and sells them to customers. Control of the Goods, including title and risk of loss, transfers to customers upon delivery at their designated seaport, and the Company has discretion in establishing prices. Accordingly, revenue from these transactions is recognized at the gross sales price.

Principles of Consolidation —The unaudited interim condensed consolidated financial statements include the accounts of SemiLEDs and its consolidated subsidiaries. All intercompany transactions and balances have been eliminated during consolidation.

On September 1, 2018, the Company adopted ASC 825-10, “Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. This standard allows equity investments that do not have readily determinable fair values to be re-measured at fair value either upon the occurrence of an observable price change or upon identification of impairment. The standard also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period.

Investments in which the Company has the ability to exercise significant influence over the investee but not a controlling financial interest, are accounted for using the equity method of accounting and are not consolidated. These investments are in joint ventures that are not subject to consolidation under the variable interest model, and for which the Company: (i) does not have a majority voting interest that would allow it to control the investee, or (ii) has a majority voting interest but for which other shareholders have significant participating rights, but for which the Company has the ability to exercise significant influence over operating and financial policies. Under the equity method, investments are stated at cost after adding or removing the Company’s portion of equity in undistributed earnings or losses, respectively. The Company’s investment in these equity‑method entities is reported in the consolidated balance sheets in investments in unconsolidated entities, and the Company’s share of the income or loss of these equity‑method entities, after the elimination of unrealized intercompany profits, is reported in the consolidated statements of operations in equity in losses from unconsolidated entities. When net losses from an equity‑method investee exceed its carrying amount, the carrying amount of the investment is reduced to zero. The Company then suspends using the equity method to provide for additional losses unless the Company has guaranteed obligations or is otherwise committed to provide further financial support to the equity‑method investee. The Company resumes accounting for the investment under the equity method if the investee subsequently returns to profitability and the Company’s share of the investee’s income exceeds its share of the cumulative losses that have not been previously recognized during the period the equity method is suspended.

Investments in entities that are not consolidated or accounted for under the equity method are recorded as investments without readily determinable fair values. Investments without readily determinable fair values are reported on the consolidated balance sheets in investments in unconsolidated entities, at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Dividend income, if any, received is reported in the consolidated statements of operations in equity in losses from unconsolidated entities.

If the fair value of an equity investment declines below its respective carrying amount and the decline is determined to be other‑than‑temporary, the investment will be written down to its fair value.

Use of Estimates —The preparation of unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the preparation of the Company’s consolidated financial statements on the basis that the Company will continue as a going concern, the collectability of accounts receivable, inventory net realizable values, realization of deferred tax assets, valuation of stock-based compensation expense, the useful lives of property, plant and equipment and intangible assets, the recoverability of the carrying amount of property, plant and equipment, intangible assets and investments in unconsolidated entities, the fair value of acquired tangible and intangible assets, income tax uncertainties, provision for potential litigation costs and other contingencies. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Management assesses these estimates on a regular basis; however, actual results could differ materially from those estimates.

Certain Significant Risks and Uncertainties —The Company is subject to certain risks and uncertainties that could have a material and adverse effect on the Company’s future financial position or results of operations, which risks and uncertainties include, among others: it has incurred significant losses over the past several years, any inability of the Company to compete in a rapidly evolving market and to respond quickly and effectively to changing market requirements, any inability of the Company to grow its revenue and/or maintain or increase its margins, it may experience fluctuations in its revenues and operating results, any inability of the Company to protect its intellectual property rights, claims by others that the Company infringes their proprietary technology, and any inability of the Company to raise additional funds in the future.

Concentration of Supply Risk —Some of the components and technologies used in the Company’s products are purchased and licensed from a limited number of sources and some of the Company’s products are produced by a limited number of contract manufacturers. The loss of any of these suppliers and contract manufacturers may cause the Company to incur transition costs to another supplier or contract manufacturer, result in delays in the manufacturing and delivery of the Company’s products, or cause it to carry excess or obsolete inventory. The Company relies on a limited number of such suppliers and contract manufacturers for the fulfillment of its customer orders. Any failure of such suppliers and contract manufacturers to perform could have an adverse effect upon the Company’s reputation and its ability to distribute its products or satisfy customers’ orders, which could adversely affect the Company’s business, financial position, results of operations and cash flows.

Concentration of Credit Risk —Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable.

The Company keeps its cash and cash equivalents in demand deposits with prominent banks of high credit quality and invests only in money market funds. Cash accounts at each institution are insured by the Federal Deposit Insurance Corporation in the United States or Central Deposit Insurance Corporation in Taiwan up to certain limits. At times, such deposits may be in excess of the insurance limit. U.S. accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. As of February 28, 2026 and August 31, 2025, the Company had no cash in excess of FDIC insured limits. The Company maintains cash in state-owned banks in Taiwan, where the insurance coverage of each bank is NTD$3,000,000 (approximately $96,077). As of February 28, 2026 and August 31, 2025, the Company had $3,500 thousand and $2,281 thousand cash in excess of the insured amount, respectively. The Company has not experienced any losses in such accounts. As of February 28, 2026 and August 31, 2025, cash and cash equivalents of the Company consisted of the following (in thousands):

	February 28,		August 31,
Cash and Cash Equivalents by Location	2026		2025
United States;
Denominated in U.S. dollars	$	187	$	187
Taiwan;
Denominated in U.S. dollars		3,572		2,163
Denominated in New Taiwan dollars		80		112
Denominated in other currencies		139		131
Total cash and cash equivalents	$	3,978	$	2,593

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment. Net revenues generated from buy-sell purchase orders of equipment represented 36% of the Company's revenues for the six months ended February 28, 2026. A significant portion of the Company’s revenues are derived from a limited number of customers, and sales are concentrated in a few select markets. Management performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. Management evaluates the need to establish an allowance for doubtful accounts for

estimated potential credit losses at each reporting period. The allowance for doubtful accounts is based on the management’s assessment of the collectability of its customer accounts. Management regularly reviews the allowance by considering certain factors, such as historical experience, industry data, credit quality, ages of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

Net revenues generated from sales to the top ten customers represented 89% and 91% of the Company’s total net revenues for the three and six months ended February 28, 2026, respectively, and 99% and 98% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

The Company’s revenues have been concentrated in a few select markets, including India, Japan, the United States and the Netherlands. Net revenues generated from sales to customers in these markets, in the aggregate, accounted for 69% and 86% of the Company’s net revenues for the three and six months ended February 28, 2026, respectively, and 98% and 97% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

Noncontrolling Interests —Noncontrolling interests are classified in the consolidated statements of operations as part of consolidated net income (loss) and the accumulated amount of noncontrolling interests in the consolidated balance sheets as part of equity. Changes in ownership interest in a consolidated subsidiary that do not result in a loss of control are accounted for as an equity transaction. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are remeasured with the gain or loss reported in net earnings.

On September 1, 2018, Taiwan Bandaoti Zhaoming Co., Ltd., formerly known as Silicon Base Development, Inc. (“SBDI”), the Company’s wholly owned operating subsidiary, issued 414,000 common shares and amended its certificate of incorporation to increase its common stock issued from 12,087,715 shares to 12,501,715 shares. As of the issuance date, the increased capital of $176 thousand (NT$5.4 million) had been completely received in cash by SBDI. SemiLEDs Optoelectronics Co., Ltd. (“Taiwan SemiLEDs”) did not subscribe for the newly issued common shares, and, as a result, the noncontrolling interest in Taiwan SemiLEDs increased from zero to 3.31%. From January 2019 to September 2020, Taiwan SemiLEDs purchased an additional 33,000 common shares of SBDI from non-controlling shareholders. From March 2022 to May 2022, Taiwan SemiLEDs purchased an additional 52,000 common shares of SBDI from non-controlling shareholders. On September 1, 2024, Taiwan SemiLEDs purchased the remaining 329,000 common shares of SBDI from non-controlling shareholders. On April 1, 2025, Taiwan Bandaoti Zhaoming Co., Ltd. merged with and into Taiwan SemiLEDs. Taiwan Bandaoti Zhaoming Co., Ltd. now functions as a division of Taiwan SemiLEDs with all property, obligations, and capital being transferred to Taiwan SemiLEDs. Taiwan SemiLEDs changed its company name to Taiwan Bandaoti Zhaoming Co., Ltd. after the merger. The noncontrolling interest in former Taiwan Bandaoti Zhaoming Co., Ltd. was zero as of February 28, 2026 and August 31, 2025.

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in ASU 2023-07 improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (CODM). In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. ASU 2023-07 became effective for annual reporting periods beginning after December 15, 2023, and interim periods within annual reporting periods beginning after December 15, 2024. The Company adopted the ASU on a retrospective basis for all prior periods presented, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The new standard requires entities to disclose additional information about certain expenses, such as purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses included in commonly presented expense captions on the income statement. The FASB further clarified the effective date in January 2025 with the issuance of ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Companies have the option to apply this guidance either on a retrospective or prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of ASU 2024-03 on its unaudited condensed consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”. ASU 2025-05 provides a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods and should be applied prospectively. Early

adoption is permitted. The Company adopted the ASU, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”). ASU 2025-06 updates the accounting guidance for internal-use software by eliminating references to software development project stages, thereby requiring companies to start capitalizing software costs when (i) management has authorized and committed to funding the project and (ii) it is probable the project will be completed and the software will be used as intended. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, with early adoption permitted. Amendments can be applied either (i) prospectively, (ii) through a modified transition approach based on the status projects and whether software costs were capitalized before the date of adoption, or (iii) retrospectively. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10 to provide specific authoritative guidance about the recognition, measurement, and presentation of a grant received by a business entity from a government. The amendments in this guidance require that a government grant received by a business entity should not be recognized until (1) it is probable that a business entity will comply with the conditions attached to the grant and the grant will be received and (2) a business entity meets the recognition guidance for a grant related to an asset or a grant related to income. Adoption of this standard is required using either a modified prospective, modified retrospective, or a retrospective approach. This standard is effective for the Company for both interim and annual reporting for the year ended December 31, 2029. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

The Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the unaudited condensed consolidated financial position, statements of operations and cash flows.

Equity Investments without Readily Determinable Fair Value

Equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the Company) which do not have readily determinable fair values are recorded as equity investment without readily determinable fair value.

All equity investments without readily determinable fair value are assessed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable, and measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuers. The recoverable value of the investment was determined based on the Company’s best estimate of the amount that could be realized from the investment, which considered the latest financial information. The impairment losses for the equity investments without readily determinable fair value were zero for the three and six months ended February 28, 2026 and 2025.

Commitments and Contingencies

5. Commitments and Contingencies

Operating Lease Agreements —The Company has several operating leases with third parties, primarily for land, plant and office spaces in Taiwan, including cancelable and noncancelable leases that expire at various dates between August 2026 and December 2040. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. For lease agreements entered into or reassessed after the adoption of Topic 842, the Company did not combine lease and non-lease components.

Most leases do not include options to renew. The exercise of lease renewal options has to be agreed by the lessors. The depreciable life of assets and leasehold improvements are limited by the term of leases, unless there is a transfer of title or purchase option reasonably certain of exercise. Lease expense is recognized on a straight-line basis over the term of the lease. Lease expense related to these noncancelable operating leases was $41 thousand and $96 thousand for three months and six months ended February 28, 2026, respectively. Lease expense related to these noncancelable operating leases was $34 thousand and $72 thousand for three months and six months ended February 28, 2025, respectively.

Purchase Obligations —The Company had purchase commitments for inventory, property, plant and equipment in the amount of $5.6 million and $461 thousand as of February 28, 2026 and August 31, 2025, respectively.

Litigation —The Company is directly or indirectly involved from time to time in various claims or legal proceedings arising in the ordinary course of business. The Company recognizes a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. There is significant judgment required in assessing both the likelihood of an unfavorable outcome and whether the amount of loss, if any, can be reasonably estimated.

As of February 28, 2026, there was no pending or threatened litigation that could have a material impact on the Company’s financial position, results of operations or cash flows.

Share-Based Payment Arrangement [Abstract]

Stock-based Compensation

6. Stock-based Compensation

The Company currently has one equity incentive plan (the “2010 Plan”), which provides for awards in the form of restricted shares, stock units, stock options or stock appreciation rights to the Company’s employees, officers, directors and consultants. In April 2014, SemiLEDs’ stockholders approved an amendment to the 2010 Plan that increases the number of shares authorized for issuance under the plan by an additional 250 thousand shares. On July 31, 2019, the stockholders approved an increase in the authorized share reserve under the 2010 plan by an additional 500 thousand shares, to extend expiration of the 2010 Plan to November 3, 2023, to remove the IRS Code section 162(m) provisions, and to modify the maximum grant limit to 35 thousand shares to one person in a one year period. On September 25, 2020, the stockholders approved an amendment to the 2010 Equity Incentive Plan to increase the authorized shares reserve by an additional 400 thousand shares. On March 17, 2023, the Board approved the amendment of the 2010 Plan to extend the term to March 17, 2033, which was approved by the Company's stockholders at the annual meeting held on May 18, 2023.

A total of 1,421 thousand and 1,421 thousand shares was reserved for issuance under the 2010 Plan as of February 28, 2026 and 2025, respectively. As of February 28, 2026 and 2025, there were 429 thousand and 530 thousand shares of common stock available for future issuance under the equity incentive plans, respectively.

In November 2025, SemiLEDs granted 15 thousand restricted stock units to its directors, which vest 25% every three months from the vesting commencement date of November 27, 2025 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $2.406 per unit.

In July 2025, SemiLEDs granted 96 thousand restricted stock units to its employees, which vest 12.5% every three months from the vesting commencement date of July 10, 2025 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $2.81 per unit.

In November 2024, SemiLEDs granted 15 thousand restricted stock units to its directors, which vest 25% every three months from the vesting commencement date of November 27, 2024 and will become fully vested upon a change in control. The grant-date fair value of the restricted stock units was $1.28 per unit.

The grant date fair value of stock options is determined using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs including the market price of SemiLEDs’ common stock on the date of grant, the term that the stock options are expected to be outstanding, the implied stock volatilities of several of the Company’s publicly-traded peers over the expected term of stock options, risk-free interest rate and expected dividend. Each of these inputs is subjective and generally requires significant judgment to determine. The grant date fair value of stock units is based upon the market price of SemiLEDs’ common stock on the date of the grant. This fair value is amortized to compensation expense over the vesting term. During the three and six months ended February 28, 2026 and 2025, the Company had no options granted, forfeited, or exercised. As of February 28, 2026 and 2025, the Company had no unvested stock options and the unrecognized compensation costs related to unvested stock options were nil.

Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. A forfeiture rate of zero is estimated for stock-based awards with vesting term that is less than or equal to one year from the date of grant.

A summary of the stock-based compensation expense for the three and six months ended February 28, 2026 and 2025 was as follows (in thousands):

	Three Months Ended				Six Months Ended

Unrecognized Tax Benefits

On December 22, 2017, the U.S. Tax Cuts and Jobs Act was adopted, which among other effects, reduced the U.S. federal corporate income tax rate to 21% from 34% (or 35% in certain cases) beginning in 2018, requires companies to pay a one-time transition tax on certain unrepatriated earnings from non-U.S. subsidiaries that is payable over eight years, makes the receipt of future non-U.S. sourced income of non-U.S. subsidiaries tax-free to U.S. companies and creates a new minimum tax on the earnings of non-U.S. subsidiaries relating to the parent’s deductions for payments to the subsidiaries. Our provisional estimate is that no tax will be due under this provision.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The provisions of the legislation that were effective for fiscal 2026 did not have a material impact on the Company's income tax expense for the three and six months ended February 28, 2026 and 2025. The Company is currently assessing the impact of the provisions of the OBBBA that are effective in future years on its future consolidated financial statements.

As of both February 28, 2026 and August 31, 2025, the Company had no unrecognized tax benefits related to tax positions taken in prior periods. The Company files income tax returns in the United States, various U.S. states and certain foreign jurisdictions. The tax years 2020 through 2024 remain open in most jurisdictions. With few exceptions, as of February 28, 2026, the Company is no longer subject to U.S. federal, state, local, or foreign examinations by tax authorities for tax years before 2020.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Feb. 28, 2026

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation —The Company’s unaudited interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and applicable provisions of the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by the rules and regulations of the SEC. Accordingly, these unaudited interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the SEC on November 28, 2025. The unaudited condensed consolidated balance sheet as of August 31, 2025 included herein was derived from the audited consolidated financial statements as of that date.

The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair presentation of the Company’s unaudited condensed consolidated balance sheet as of February 28, 2026, the unaudited condensed statements of operations and comprehensive loss for the three and six months ended February 28, 2026 and 2025, the unaudited condensed statement of changes in equity for the three and six months ended February 28, 2026 and 2025, and the unaudited condensed statements of cash flows for the six months ended February 28, 2026 and 2025. The results for the three or six months ended February 28, 2026 are not necessarily indicative of the results to be expected for the year ending August 31, 2026.

Going Concern

Going Concern —The accompanying unaudited interim condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The realization of assets and the satisfaction of liabilities in the normal course of business are dependent on, among other things, the Company’s ability to operate profitably, to generate cash flows from operations, and to pursue financing arrangements to support its working capital requirements.

The Company suffered losses from operations of $1.6 million and $2.9 million, and net cash provided by operating activities of $2.2 million and net cash used in operating activities of $361 thousand, for the years ended August 31, 2025 and 2024, respectively. These facts and conditions have raised substantial doubt about the Company’s ability to continue as a going concern, even though gross profit on product sales was $2.4 million for the year ended August 31, 2025 compared to $1.1 million for the year ended August 31, 2024. On February 28, 2026, the Company’s cash and cash equivalents had increased to $4.0 million compared to $2.4 million on February 28, 2025. Further, loss from operations was $845 thousand and $1.9 million for the three and six months ended February 28, 2026, respectively. Management believes that it has developed a liquidity plan, as summarized below, that, if executed successfully, should provide sufficient liquidity to meet the Company’s obligations as they become due for a reasonable period of time, and allow the development of its core business. The plan includes:

•Gaining positive cash-inflow from operating activities through continuous cost reductions and the sales of new higher margin products. Steady growth of module products and the continued commercial sales of its UV LED product are expected to improve the Company’s future gross margin, operating results and cash flows. The Company is targeting niche markets and focusing on product enhancement and developing its LED products into many other applications or devices.

•Continuing to monitor prices, work with current and potential vendors to decrease costs and, consistent with its existing contractual commitments, possibly decrease its activity level and capital expenditures further. This plan reflects its strategy of controlling capital costs and maintaining financial flexibility.

•Raising additional cash through potential equity offerings, sales of assets and/or issuance of debt as considered necessary and looking at other potential business opportunities.

While the Company's management believes that the measures described in the above liquidity plan will be adequate to satisfy its liquidity requirements for the twelve months after the date that the financial statements are issued, there is no assurance that the liquidity plan will be successfully implemented. Failure to successfully implement the liquidity plan may have a material adverse effect on its business, results of operations and financial position, and may adversely affect its ability to continue as a going concern. These unaudited interim condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern.

Restricted Cash Equivalents

Restricted Cash —Restricted cash primarily consists of cash held in reserved bank accounts in Taiwan, including compensating balances required under the Company's long-term loan requirements. As of February 28, 2026 and August 31, 2025, the Company’s restricted cash at noncurrent portion, which was recorded as other assets, amounted to $173 thousand and $177 thousand, respectively.

Revenue Recognition

Revenue Recognition —Effective September 1, 2018, the Company adopted ASC 606 using the modified retrospective transition method. The Company applied the following five steps to achieve the core principles of ASC 606: 1) identified the contract with a customer; 2) identified the performance obligations (promises) in the contract; 3) determined the transaction price; 4) allocated the transaction price to the performance obligations in the contract; and 5) recognized revenue when (or as) the Company satisfies a performance obligation.

The Company recognizes the amount of revenue, when the Company satisfies a performance obligation, to which it expects to be entitled for the transfer of promised goods or services to customers. The Company obtains written purchase authorizations from its customers as evidence of an arrangement and these authorizations generally provide for a specified amount of product at a fixed price. Generally, the Company considers delivery to have occurred at the time of shipment as this is generally when title and risk of loss for the products will pass to the customer. The Company provides its customers with limited rights of return for non‑conforming shipments and product warranty claims. Based on historical return percentages, which have not been material to date, and other relevant factors, the Company estimates its potential future exposure on recorded product sales, which reduces product revenues in the consolidated statements of operations and reduces accounts receivable in the consolidated balance sheets. The Company also provides standard product warranties on its products, which generally range from three months to two years. Management estimates the Company’s warranty obligations as a percentage of revenues, based on historical knowledge of warranty costs and other relevant factors. To date, the related estimated warranty provisions have been insignificant.

Gross Versus Net Revenue —ASC 606 provides guidance on proper recognition of principal versus agent considerations which are used to determine gross versus net revenue recognition. Under ASC 606, the core objective of the guidance on gross versus net revenue recognition is to help determine whether an entity is a principal or an agent in a transaction. In general, the primary difference between these two is the performance obligation being satisfied. The principal has a performance obligation to provide the desired goods or services to the end customer, whereas the agent arranges for the principal to provide the desired goods or services. Additionally, a fundamental characteristic of a principal in a transaction is control. A principal substantively controls the goods and services before they are transferred to the customer as well as controls the price of the good or service being provided. An agent normally receives a

commission or fee for these activities. In addition to control, the level at which an entity controls the price of the good or service being transferred determines principal versus agent status. The more discretion over setting price a company has in providing the good or service, the more likely they are considered a principal rather than an agent. Under the guidance when another party is involved in providing a good or service to a customer, an entity is a principal if the entity obtains control of the asset or right to a service performed by the other party.

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment.

Under buy-sell purchase orders, the Company purchases certain machinery and equipment (the “Goods”) from vendors and sells them to customers. Control of the Goods, including title and risk of loss, transfers to customers upon delivery at their designated seaport, and the Company has discretion in establishing prices. Accordingly, revenue from these transactions is recognized at the gross sales price.

Principles of Consolidation

Principles of Consolidation —The unaudited interim condensed consolidated financial statements include the accounts of SemiLEDs and its consolidated subsidiaries. All intercompany transactions and balances have been eliminated during consolidation.

On September 1, 2018, the Company adopted ASC 825-10, “Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities”. This standard allows equity investments that do not have readily determinable fair values to be re-measured at fair value either upon the occurrence of an observable price change or upon identification of impairment. The standard also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring assessment for impairment qualitatively at each reporting period.

Investments in which the Company has the ability to exercise significant influence over the investee but not a controlling financial interest, are accounted for using the equity method of accounting and are not consolidated. These investments are in joint ventures that are not subject to consolidation under the variable interest model, and for which the Company: (i) does not have a majority voting interest that would allow it to control the investee, or (ii) has a majority voting interest but for which other shareholders have significant participating rights, but for which the Company has the ability to exercise significant influence over operating and financial policies. Under the equity method, investments are stated at cost after adding or removing the Company’s portion of equity in undistributed earnings or losses, respectively. The Company’s investment in these equity‑method entities is reported in the consolidated balance sheets in investments in unconsolidated entities, and the Company’s share of the income or loss of these equity‑method entities, after the elimination of unrealized intercompany profits, is reported in the consolidated statements of operations in equity in losses from unconsolidated entities. When net losses from an equity‑method investee exceed its carrying amount, the carrying amount of the investment is reduced to zero. The Company then suspends using the equity method to provide for additional losses unless the Company has guaranteed obligations or is otherwise committed to provide further financial support to the equity‑method investee. The Company resumes accounting for the investment under the equity method if the investee subsequently returns to profitability and the Company’s share of the investee’s income exceeds its share of the cumulative losses that have not been previously recognized during the period the equity method is suspended.

Investments in entities that are not consolidated or accounted for under the equity method are recorded as investments without readily determinable fair values. Investments without readily determinable fair values are reported on the consolidated balance sheets in investments in unconsolidated entities, at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Dividend income, if any, received is reported in the consolidated statements of operations in equity in losses from unconsolidated entities.

If the fair value of an equity investment declines below its respective carrying amount and the decline is determined to be other‑than‑temporary, the investment will be written down to its fair value.

Use of Estimates

Use of Estimates —The preparation of unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited interim condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include the preparation of the Company’s consolidated financial statements on the basis that the Company will continue as a going concern, the collectability of accounts receivable, inventory net realizable values, realization of deferred tax assets, valuation of stock-based compensation expense, the useful lives of property, plant and equipment and intangible assets, the recoverability of the carrying amount of property, plant and equipment, intangible assets and investments in unconsolidated entities, the fair value of acquired tangible and intangible assets, income tax uncertainties, provision for potential litigation costs and other contingencies. Management bases its estimates on historical experience and also on assumptions that it believes are reasonable. Management assesses these estimates on a regular basis; however, actual results could differ materially from those estimates.

Certain Significant Risks and Uncertainties

Certain Significant Risks and Uncertainties —The Company is subject to certain risks and uncertainties that could have a material and adverse effect on the Company’s future financial position or results of operations, which risks and uncertainties include, among others: it has incurred significant losses over the past several years, any inability of the Company to compete in a rapidly evolving market and to respond quickly and effectively to changing market requirements, any inability of the Company to grow its revenue and/or maintain or increase its margins, it may experience fluctuations in its revenues and operating results, any inability of the Company to protect its intellectual property rights, claims by others that the Company infringes their proprietary technology, and any inability of the Company to raise additional funds in the future.

Concentration of Supply Risk

Concentration of Supply Risk —Some of the components and technologies used in the Company’s products are purchased and licensed from a limited number of sources and some of the Company’s products are produced by a limited number of contract manufacturers. The loss of any of these suppliers and contract manufacturers may cause the Company to incur transition costs to another supplier or contract manufacturer, result in delays in the manufacturing and delivery of the Company’s products, or cause it to carry excess or obsolete inventory. The Company relies on a limited number of such suppliers and contract manufacturers for the fulfillment of its customer orders. Any failure of such suppliers and contract manufacturers to perform could have an adverse effect upon the Company’s reputation and its ability to distribute its products or satisfy customers’ orders, which could adversely affect the Company’s business, financial position, results of operations and cash flows.

Concentration of Credit Risk

Concentration of Credit Risk —Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents and accounts receivable.

The Company keeps its cash and cash equivalents in demand deposits with prominent banks of high credit quality and invests only in money market funds. Cash accounts at each institution are insured by the Federal Deposit Insurance Corporation in the United States or Central Deposit Insurance Corporation in Taiwan up to certain limits. At times, such deposits may be in excess of the insurance limit. U.S. accounts are guaranteed by the Federal Deposit Insurance Corporation (FDIC) up to $250,000. As of February 28, 2026 and August 31, 2025, the Company had no cash in excess of FDIC insured limits. The Company maintains cash in state-owned banks in Taiwan, where the insurance coverage of each bank is NTD$3,000,000 (approximately $96,077). As of February 28, 2026 and August 31, 2025, the Company had $3,500 thousand and $2,281 thousand cash in excess of the insured amount, respectively. The Company has not experienced any losses in such accounts. As of February 28, 2026 and August 31, 2025, cash and cash equivalents of the Company consisted of the following (in thousands):

	February 28,		August 31,
Cash and Cash Equivalents by Location	2026		2025
United States;
Denominated in U.S. dollars	$	187	$	187
Taiwan;

Denominated in New Taiwan dollars		80		112
Denominated in other currencies		139		131
Total cash and cash equivalents	$	3,978	$	2,593

The Company’s revenues for the six months ended February 28, 2026 were significantly derived from buy-sell purchase orders of equipment. Net revenues generated from buy-sell purchase orders of equipment represented 36% of the Company's revenues for the six months ended February 28, 2026. A significant portion of the Company’s revenues are derived from a limited number of customers, and sales are concentrated in a few select markets. Management performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable. Management evaluates the need to establish an allowance for doubtful accounts for

estimated potential credit losses at each reporting period. The allowance for doubtful accounts is based on the management’s assessment of the collectability of its customer accounts. Management regularly reviews the allowance by considering certain factors, such as historical experience, industry data, credit quality, ages of accounts receivable balances and current economic conditions that may affect a customer’s ability to pay.

Net revenues generated from sales to the top ten customers represented 89% and 91% of the Company’s total net revenues for the three and six months ended February 28, 2026, respectively, and 99% and 98% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

The Company’s revenues have been concentrated in a few select markets, including India, Japan, the United States and the Netherlands. Net revenues generated from sales to customers in these markets, in the aggregate, accounted for 69% and 86% of the Company’s net revenues for the three and six months ended February 28, 2026, respectively, and 98% and 97% of the Company’s net revenues for the three and six months ended February 28, 2025, respectively.

Noncontrolling Interests

Noncontrolling Interests —Noncontrolling interests are classified in the consolidated statements of operations as part of consolidated net income (loss) and the accumulated amount of noncontrolling interests in the consolidated balance sheets as part of equity. Changes in ownership interest in a consolidated subsidiary that do not result in a loss of control are accounted for as an equity transaction. If a change in ownership of a consolidated subsidiary results in loss of control and deconsolidation, any retained ownership interests are remeasured with the gain or loss reported in net earnings.

On September 1, 2018, Taiwan Bandaoti Zhaoming Co., Ltd., formerly known as Silicon Base Development, Inc. (“SBDI”), the Company’s wholly owned operating subsidiary, issued 414,000 common shares and amended its certificate of incorporation to increase its common stock issued from 12,087,715 shares to 12,501,715 shares. As of the issuance date, the increased capital of $176 thousand (NT$5.4 million) had been completely received in cash by SBDI. SemiLEDs Optoelectronics Co., Ltd. (“Taiwan SemiLEDs”) did not subscribe for the newly issued common shares, and, as a result, the noncontrolling interest in Taiwan SemiLEDs increased from zero to 3.31%. From January 2019 to September 2020, Taiwan SemiLEDs purchased an additional 33,000 common shares of SBDI from non-controlling shareholders. From March 2022 to May 2022, Taiwan SemiLEDs purchased an additional 52,000 common shares of SBDI from non-controlling shareholders. On September 1, 2024, Taiwan SemiLEDs purchased the remaining 329,000 common shares of SBDI from non-controlling shareholders. On April 1, 2025, Taiwan Bandaoti Zhaoming Co., Ltd. merged with and into Taiwan SemiLEDs. Taiwan Bandaoti Zhaoming Co., Ltd. now functions as a division of Taiwan SemiLEDs with all property, obligations, and capital being transferred to Taiwan SemiLEDs. Taiwan SemiLEDs changed its company name to Taiwan Bandaoti Zhaoming Co., Ltd. after the merger. The noncontrolling interest in former Taiwan Bandaoti Zhaoming Co., Ltd. was zero as of February 28, 2026 and August 31, 2025.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The amendments in ASU 2023-07 improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (CODM). In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. ASU 2023-07 became effective for annual reporting periods beginning after December 15, 2023, and interim periods within annual reporting periods beginning after December 15, 2024. The Company adopted the ASU on a retrospective basis for all prior periods presented, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses. The new standard requires entities to disclose additional information about certain expenses, such as purchases of inventory, employee compensation, depreciation, intangible asset amortization, as well as selling expenses included in commonly presented expense captions on the income statement. The FASB further clarified the effective date in January 2025 with the issuance of ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. The ASU is effective for fiscal years beginning after December 15, 2026 and interim periods beginning after December 15, 2027. Companies have the option to apply this guidance either on a retrospective or prospective basis, and early adoption is permitted. The Company is currently evaluating the impact of ASU 2024-03 on its unaudited condensed consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU 2025-05, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets”. ASU 2025-05 provides a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025 and interim reporting periods within those annual reporting periods and should be applied prospectively. Early

adoption is permitted. The Company adopted the ASU, and the adoption had no material effect on the unaudited condensed consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2025-06”). ASU 2025-06 updates the accounting guidance for internal-use software by eliminating references to software development project stages, thereby requiring companies to start capitalizing software costs when (i) management has authorized and committed to funding the project and (ii) it is probable the project will be completed and the software will be used as intended. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, with early adoption permitted. Amendments can be applied either (i) prospectively, (ii) through a modified transition approach based on the status projects and whether software costs were capitalized before the date of adoption, or (iii) retrospectively. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10 to provide specific authoritative guidance about the recognition, measurement, and presentation of a grant received by a business entity from a government. The amendments in this guidance require that a government grant received by a business entity should not be recognized until (1) it is probable that a business entity will comply with the conditions attached to the grant and the grant will be received and (2) a business entity meets the recognition guidance for a grant related to an asset or a grant related to income. Adoption of this standard is required using either a modified prospective, modified retrospective, or a retrospective approach. This standard is effective for the Company for both interim and annual reporting for the year ended December 31, 2029. The Company is currently evaluating the impact of ASU 2025-06 on its unaudited condensed consolidated financial statements and related disclosures.

The Company does not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the unaudited condensed consolidated financial position, statements of operations and cash flows.
