In accordance with those rules and regulations, the Company has omitted certain information and notes required by GAAP for annual consolidated financial statements. In the opinion of management, the condensed consolidated financial statements contain all adjustments, except as otherwise noted, necessary for the fair presentation of the Company’s financial position and results of operations for the periods presented.

​

Use of Estimates

​

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from those estimates in the consolidated financial statements and accompanying notes. Significant estimates and assumptions that impact these financial statements and the accompanying notes relate to, among other things, revenue recognition, allowance for credit losses, inventory reserve, impairment of long-lived assets, service and product warranty costs, share-based compensation expense, estimated useful lives of tangible and intangible assets, and taxes.

Product Warranty

The Company generally offers aone-year limited warranty for its products but it can extend for longer periods ofthree tofive years for certain products sold to certain customers. The Company estimates the costs that* maybe incurred under its basic limited warranty and records a liability for the amount of such costs at the time when product defects occur. Factors that affect the Company’s warranty liability include the historical and anticipated rates of warranty claims and cost to repair. While the Company believes that its warranty accrual is adequate, the actual warranty costs mayexceed the accrual, in which case the cost of sales will increase in the future. As of March 31, 2026* and* December 31, 2025*, the amount of accrued warranty was $0.47 million and $0.48 million, respectively.

Customer Warrant

On* March 13, 2025,the Company issued a warrant (the "Customer Warrant") to a wholly-owned subsidiary of Amazon.com, Inc. to purchase up to an aggregate of 7,945,399 shares of the Company's common stock ("Warrant Shares") at an exercise price of $23.6956 per share. The Customer Warrant has a contractual term of 10 years. At the time of the issuance, the Customer Warrant is exercisable to purchase 1,324,233 Warrant Shares. The remaining 6,621,166 Warrant Shares mayvest over the next10* years, dependent on aggregate purchases by or on behalf of Amazon and its affiliates of $4 billion of the Company's products over this time period. The Company accounts for the Customer Warrant as an equity classified share-based consideration to a customer and will recognize the grant-date fair value of the Customer Warrant as a reduction of revenue from Amazon as the related goods or services are transferred. The grant date fair value of the Customer Warrant was determined to be $12.64 per share, using the Black-Scholes-Merton option pricing model.

The per share grant date fair value of the Customer Warrant was estimated using the following assumptions:

Note4. Leases

​

The Company leases space under non-cancellable operating leases for manufacturing facilities, research and development offices and certain storage facilities and apartments. These leases donot contain contingent rent provisions. The Company also leases certain machinery, office equipment and a vehicle under operating leases. The Company determines if an arrangement is or contains a lease at contract inception. Many of its leases include both lease (e.g. fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g. common-area or other maintenance costs) which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. Several of the leases includeone or more options to renew which have been assessed and either included or excluded from the calculation of the lease liability of the right of use ("ROU") asset based on management’s intentions and individual fact patterns. Several warehouses and apartments have non-cancellable lease terms of less thanone-year and therefore, the Company has elected the practical expedient to exclude these short-term leases from its ROU asset and lease liabilities.

On* October 7, 2024,Prime World entered into a Land and Building Lease Agreement with San Ho Enterprise Co., Ltd. ("San Ho Enterprise"), under which Prime World will lease approximately 38,072 square feet, oftwo* adjoining parcels of land, in New Taipei City.

Beginning in theeighth month of the term, base rent will be $7.44 per rentable square foot on an annual basis (approximately $129,992 per month), escalating periodically to $10.49 per rentable square foot on an annual basis (approximately $183,367 per month) during the finalsix months of the term. The total undiscounted lease payments over the initial lease term are approximately $18.5 million.

The Company is required to pay (i) prepaid rent of $163,164 to be applied against theeleventh month’s rent and (ii) an initial security deposit of $2 million, which accrues interest and is subject to partial reductions during the lease term if specified payment-performance conditions are satisfied. The lease provides for scheduled reductions of the security deposit of $0.5 million after40 months, $0.5 million after70 months, and $0.34 million after100 months, subject to the Companynot being in default and other conditions set forth in the Lease. The total undiscounted lease payments over the initial lease term are approximately $19.5 million. As of* March 31, 2026,*we recorded $12.5 million ROU asset and $12.8 million lease liability related to this agreement.

As most of the Company’s leases donot provide an implicit rate, the Company uses its incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Based on the applicable lease terms and current economic environment, the Company applies a location approach for determining the incremental borrowing rate.

Note6. Earnings (Loss) Per Share

​

Basic net loss per share has been computed using the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share has been computed using the weighted-average number of shares of common stock and dilutive potential common shares from stock options, restricted stock units and senior convertible notes outstanding during the period. In periods with net losses, normally dilutive shares become anti-dilutive. Therefore, basic and diluted loss per share are the same. On* March 13, 2025,the Company issued 7,945,399 stock warrants to a subsidiary of Amazon, and 1,324,233 warrants have been vested upon signing the warrant agreement. For thethree* months ended* March 31, 2026,*such warrants are in the money and are considered dilutive instruments.

​

The carrying value amounts of cash and cash equivalents, restricted cash, accounts receivable, prepaid expenses, notes receivable and other current assets, accounts payable, accrued expenses, bank acceptance payable and other current liabilities approximate fair value because of the short-term maturity of these instruments. The Company believes that the interest rates in effect at each period end represent the current market rates for similar borrowings.

The fair value of convertible senior notes is measured for disclosure purposes only. The fair value and carrying amount of our convertible senior notes as of* March 31, 2026* was $278.7 million and $129.5 million, respectively. As of* December 31, 2025*, the fair value and carrying amount of our convertible senior notes was $145.2 million and $129.8 million, respectively.

The2030 Notes will be redeemable, in whole or in part (subject to certain limitations described in the Indenture), at the Company’s option at any time, and from time to time, on or after* January 15, 2027and on or before the40th* scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, but only if the last reported sale price per share of the Common Stock exceeds 130% of the conversion price on (1) each of at least 20 trading days, whether ornot consecutive, during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice; and (2) the trading day immediately before the date it sends such notice.

In addition, the2030 Notes will be redeemable, in whole or in part, at the Company’s option at any time, and from time to time, on or before the40th scheduled trading day immediately before the maturity date, at a cash redemption price equal to the principal amount of the2030 Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date (subject to the right of a holder of2030 Notes as of the close of business on a record date to receive the related interest payment on the corresponding interest payment date), if the “Specified Divestiture” (as defined in the Indenture) is completed.

15

Calling any2030 Note for redemption will constitute a "Make-Whole Fundamental Change" (as defined in the Indenture) with respect to that2030 Note, in which case the conversion rate applicable to the conversion of that2030 Note will be increased in certain circumstances if it is converted after it is called for redemption.

In addition, if the Specified Divestiture is completed, then unless the Company has previously elected to redeem all of the2030 Notes, each holder of2030 Notes will have the right to require the Company to repurchase its2030 Notes for cash on a date of the Company’s choosing, which must be a business day that isno more than35, nor less than20, business days after the date the Company’s sends the related notice of Specified Divestiture. The repurchase price for a note tendered for such repurchase will be equal to the principal amount of the2030 Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the repurchase date (subject to the right of a holder of2030 Notes as of the close of business on a record date to receive the related interest payment on the corresponding interest payment date).

Moreover, if the Company undergoes a fundamental change, as described in the Indenture, holders of the2030 Notes* mayrequire the Company to repurchase for cash all or part of their2030* Notes at a repurchase price equal to 100% of the principal amount of the2030 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the required repurchase date.

Additionally, the2030 Notes are subject to customary events of default. The2030 Notes donot restrict the Company’s ability to incur debt or liens.No sinking fund is provided for the2030 Notes. There areno guarantors of the2030 Notes.

Pursuant to the guidance in ASC815-40, Contracts in Entity’s Own Equity, the Company evaluated whether the conversion feature of the note needed to be bifurcated from the host instrument as a freestanding financial instrument. Under ASC815-40, to qualify for equity classification (or non-bifurcation, if embedded) the instrument (or embedded feature) must be both (1) indexed to the issuer’s own stock and (2) meet the requirements of the equity classification guidance. Based upon the Company’s analysis, it was determined the conversion option is indexed to its own stock and also met all the criteria for equity classification. Accordingly, the conversion option isnot required to be bifurcated from the host instrument as a derivative.

Pursuant to ASC815-15, the Company further determined that the contingent redemption features in the2030 Notes arenot required to be bifurcated from the host contract and accounted for separately. Additionally, the Company then evaluated whether the conversion feature needed to be separately accounted for as an equity component under ASC470-20, Debt with Conversion and Other Options, and determined that the additional premium wasnot substantial. Accordingly, that amount was recognized as a premium on the2030 Notes.

Equity Plans

​

The Company’s board of directors and stockholders approved the following equity plans:

​

The Company has issued stock options, restricted stock awards ("RSAs") and restricted stock units ("RSUs") to employees, consultants and non-employee directors. Stock option awards generally vest over afour-year period and have a maximum term often years. Stock options under these plans have been granted with an exercise price equal to the fair market value on the date of the grant. Nonqualified and Incentive Stock Options, RSAs and RSUs* may*be granted from these plans.

​

Performance Based Incentive Plan

​Starting in2021, certain senior executives were granted performance stock units ("PSUs") under our2021 Plan, which generally vest over athree-year period subject to achievement of certain pre-established performance metrics. The number of shares of common stock that would ultimately be issued to settle PSUs granted ranged from 0% to 200% of the target number of shares granted. We estimate the fair value of the PSUs on the date of grant using a Monte Carlo simulation model, with stock-based compensation expense recognized ratably over the applicablethree-year performance period. The Company recognized stock-based compensation expense for the PSUs for thethree months ended* March 31, 2026and2025* of $1.9 million and $0.9 million, respectively.

The following is a summary of PSU activity for thethree months ended* March 31, 2026:*

As of* March 31, 2026*, there was $18.9 million of unrecognized stock-based compensation expense related to outstanding PSUs, which expense is expected to be recognized over 2.6 years.

Restricted Stock Units

Restricted stock units are issued to employees through a vesting plan and distribution schedule after employee remains with the Company for a particular length of time. The following is a summary of RSU activity:

​

As of* March 31, 2026*, there was $26.7 million of unrecognized compensation expense related to these RSUs. This expense is expected to be recognized over 3.2 years.

Note16. Income Taxes

​​

For thethree months ended* March 31, 2026,the Company recorded an income tax expense of $1.0 million, compared withno income tax expense or benefit for thethree* months ended* March 31, 2025.*The income tax expense for the current period was primarily attributable to income in foreign jurisdictions, as well as the impact of valuation allowances and discrete items.

For thethree months ended* March 31, 2026and2025,* the effective tax rate of (7.9)% and 0.0% differed from the U.S. federal statutory rate of 21%, primarily due to the impact of valuation allowances recorded against deferred tax assets ("DTA") in the United States and Taiwan.

The Company assesses the realizability of its DTAs, including an analysis of factors such as future taxable income, reversal of existing taxable temporary differences, and tax planning strategies. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence related to the likelihood of realization of deferred tax assets using a “more likely thannot” standard. In making such assessment, more weight was given to evidence that could be objectively verified, including recent cumulative losses. Based on the Company’s review of this evidence, management determined that a full valuation allowance against all of the Company’s US and Taiwan net deferred tax assets remains appropriate as of* March 31, 2026.*

The Company expects any earnings of foreign subsidiaries to be indefinitely invested outside the United States. As of* December 31, 2025,however, the Company doesnot have any accumulated undistributed earnings generated by foreign subsidiaries and has estimated that its tax basis in foreign subsidiaries exceeds its book basis. The Company has concluded thatno* deferred tax asset (DTA) should be recorded because at the present time it doesnot expect that the temporary book-tax basis difference that would create this DTA will reverse in the foreseeable future.

Note17. Segment and Geographic Information

​

The Company operates inone reportable segment. The Company’s Chief Executive Officer, who is considered to be the chief operating decision maker ("CODM"), manages the Company’s operations as a whole and reviews financial information presented on a consolidated basis, accompanied by information about product revenue, for purposes of evaluating financial performance and allocating resources. Our CEO is the functional head of all operations and manufacturing. Our Board, in conjunction with our CODM, considers our consolidated performance and doesnot have individual financial or operating goals for each location, nor for any other subset of the Company's operations. As such, the Company has determined it operates asone reportable segment.

Our CODM uses net income or loss to allocate resources and assess performance. The CODM regularly reviews the consolidated net income or loss to make strategic decisions, such as capital expenditure plan, production plan and manpower allocation. The following table is in thousands.

We exclude share-based compensation and related expense, certain legal expenses associated with litigation and otherone-time expenses from adjusted research and development, adjusted sales and marketing and adjusted general and administrative expenses.

Other segment items include share-based compensation expense, interest expense, interest income, certain legal expenses associated with litigation and otherone-time items.

Note18. Commitments and Contingencies

​

Litigation

​

From time to time, the Company* maybe subject to legal proceedings and litigation arising in the ordinary course of business, including, butnot* limited to, inquiries, investigations, audits and other regulatory proceedings, such as described below. The Company records a loss provision when it believes it is both probable that a liability has been incurred and the amount can be reasonably estimated.

The Company believes that there areno claims or actions pending or threatened against it, the ultimate disposition of which would have a material adverse effect on it.

Other Contingencies

On* August 9, 2021,the Company received a Taxes Notification of Audit Result ("Notice") from the Texas Comptroller’s Office (the "Comptroller"), for fiscal years between2016* and2019, informing the Company that the Comptroller believes the Company didnot qualify for certain sales and use tax exemptions on various Research and Development purchases and accordingly the Company is liable for Sale and Use Tax in the amount of approximately $1.0 million including interest charges. The Company paid $0.4 million for the tax notice in* May 2021,but challenged the remaining tax assessments and vigorously defended its position. The Comptroller’s office exhausted its redetermination period and therefore moved the Company’s case to the hearing process.No hearing date has yet been scheduled, and as a result the Company isnot* able to determine the outcome of this sales tax dispute or the likelihood or amount of the Company’s loss, if any, arising from this matter.

On* February 20, 2026,the United States Supreme Court issued a ruling invalidating certain tariffs previously imposed under the International Emergency Economic Powers Act (“IEEPA”). Following this ruling, the U.S. Court of International Trade issued an order directing U.S. Customs and Border Protection (“CBP”) to establish a process for the submission and review of refund claims related to affected IEEPA tariffs. On April 20, 2026,CBP launched an online portal through which companies maysubmit IEEPA tariff refund requests. On April 29,the Company submitted refund claims totaling $5.7 million. Submitted claims are subject to review and validation by CBP, and while the vast majority of these claims are unliquidated, the approval, timing, and amount of any refunds remain subject to CBP determination. Because of these uncertainties, the Company cannot reasonably estimate the amount or timing of any refund and therefore it hasnot* recognized a receivable as of* March 31,*2026e. The Company will continue to evaluate new information and will recognize the refund when the requirements under ASC450, Contingencies, have been met.

Note19. Subsequent Events

​
