Receivables, net

The Company’s accounts receivable arise from sales on credit to customers. The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The estimate is determined by using the loss-rate method, which requires an estimation of loss rates based upon historical loss experience adjusted for factors that are relevant to determining the expected collectability of accounts receivables. Some of these factors include macroeconomic conditions that correlate with historical loss experience, delinquency trends, aging behavior of receivables and credit and liquidity indicators for individual customers.

Commitments and Contingencies Disclosure [Abstract]

Commitments and contingencies

Note 13. Commitments and contingencies

The Company recognizes the fair value for guarantee and indemnification arrangements it issues or modifies, if these arrangements are within the scope of authoritative accounting guidance. In addition, the Company must continue to monitor the conditions that are subject to the guarantees and indemnifications in order to identify if a loss has been incurred. If the Company determines it is probable that a loss has occurred, then any such estimated loss would be recognized under those guarantees and indemnifications and would be recognized in the Company’s consolidated statements of operations and corresponding consolidated balance sheets during that period.

Amended credit agreement

Our Amended Credit Agreement contains customary provisions with respect to the consequences of a “Default” or “Event of Default” as defined therein, including a restriction on the ability to access further borrowings as well as other customary rights and remedies available to the lender upon a Default or Event of Default. These include the ability to impose a default rate interest rate, prohibiting us from reinvesting asset sale proceeds, limiting repayment of intercompany debt and investment in non-loan party subsidiaries, limiting acquisitions, certain asset sales and assumption of indebtedness, and acceleration of the outstanding obligations and exercise of other remedies under the Amended Credit Agreement, among other customary restrictions.

Purchase commitments with contract manufacturers and suppliers

The Company purchase components from a variety of suppliers and use contract manufacturers to provide manufacturing services for our products and issue purchase orders for these products and services. As of December 31, 2025, the Company had $28.3 million of open purchase orders with its suppliers and contract manufacturers, expected to be procured within the next year. In addition, during the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, we enter into agreements with contract manufacturers and suppliers that allow them to procure inventory based upon criteria as defined by us, such as forecasted demand. The Company may be liable to purchase excess product or aged material from our suppliers following reasonable mitigation efforts. The Company establishes a loss on purchase commitment liability for all product the supplier has procured for which the Company does not expect it will sell. Such loss on purchase commitment liability is included in Accrued liabilities and Other noncurrent liabilities on the Company's consolidated balance sheets, based on the timing of when the liability is expected to be resolved. The Company recorded losses on purchase commitments of $7.4 million and recoveries on purchase commitments of $5.8 million for the years ended December 31, 2024 and 2025, respectively. Including the $28.3 million of open purchase orders noted above, as of December 31, 2025 the Company has $110.2 million of purchase commitments with its contract manufacturers and suppliers, of which $99.3 million is expected to be procured within the next year and $10.8 million within the next five years thereafter.

Warranties

The Company offers a standard warranty on its products, with the term depending on the product, and records a liability for the estimated future costs associated with potential warranty claims. The Company’s responsibility under its standard warranty is the repair or replacement of in-warranty defective product, or to credit the purchase price of the defective product, at its discretion, without charge to the customer. The Company’s estimate of future warranty costs is largely based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. The standard warranty is included in either Other current liabilities or Other noncurrent liabilities on the Company’s consolidated balance sheets, depending on the time period covered by the warranty. The Company also offers an extended warranty for purchase that represents a future performance obligation for the Company. The extended warranty is included in deferred revenues (both current and noncurrent) on the consolidated balance sheets and recognized on a straight-line basis over the term of the extended warranty. The warranty costs are reflected in the Company’s consolidated statements of operations within cost of revenues.

Indemnification

The Company generally indemnifies its distributors against claims brought by a third party to the extent any such claim alleges that the Company’s product infringes a patent, copyright or trademark or violates any other proprietary rights of that third party. Although the Company generally tries to limit the maximum amount of potential future liability under its indemnification obligations, in certain agreements this liability may be unlimited. The maximum potential amount of future payments the Company may be required to make under these indemnification agreements is not estimable. The Company did not make any payments under indemnification agreements in 2024 or 2025.

The Company indemnifies its directors and officers and select key employees, including key employees serving as directors or officers of the Company’s subsidiaries, for certain events or occurrences, subject to certain limits, while the director or officer is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the director’s or officer’s term of service. The Company may terminate the indemnification agreements with its directors, officers or key employees upon the termination of their services as directors or officers of the Company or its subsidiaries, or the termination of activities for which indemnification has been provided, but termination will not affect claims for indemnification related to events occurring prior to the effective date of termination. The maximum amount of potential future indemnification is unlimited; however, the Company has a director and officer insurance policy that limits its exposure. The Company believes the fair value of these indemnification agreements is minimal.

Legal proceedings

Third parties may from time to time assert legal claims against the Company. The Company records accruals for loss contingencies to the extent that it concludes it is probable that a liability has been incurred and the amount of the related loss can be reasonably estimated. The Company evaluates, on a regular basis, developments in legal proceedings and other matters that could cause a change in amounts recorded. Due to the inherent uncertainty involving legal matters, the ultimate resolution could differ from amounts recorded. There is no pending or threatened legal proceedings to which the Company is a party to, and in the Company’s opinion, is likely to have a material adverse effect on its financial condition or results of operations.

Shareholder lawsuit

On May 22, 2024, a putative shareholder class action complaint was filed in the United States District Court for the Northern District of Illinois (Hamby v. Cambium Networks Corporation et al, Case No. 1:24-cv-04240) against us and three of our current or former officers. The complaint purported to assert claims under Section 10(b) of the Exchange Act, Exchange Act Rule 10b-5, and Section 20(a) of the Exchange Act, on behalf of persons and entities who acquired our ordinary shares between May 8, 2023 and January 18, 2024 ("Class Period"). The complaint alleged that, during the Class Period, the Company and certain of its executive officers made false and misleading statements and failed to disclose material adverse facts about its business, operations, and prospects in violation of Sections 10(b) (and Rule 10b-5 promulgated thereunder) and 20(a) of the Exchange Act. The plaintiffs sought damages in an unspecified amount. On July 22, 2024, motions were filed on behalf of purported class member shareholders seeking to serve as lead plaintiff. On October 21, 2024, the court approved the appointment of lead plaintiff. On December 4, 2024, plaintiffs filed a voluntary dismissal of the action without prejudice.

Nasdaq Noncompliance

On March 25, 2026, the Company received a written notice that the Nasdaq Hearings Panel (the “Hearings Panel”) had determined to delist the Company's ordinary shares from The Nasdaq Global Market due to the Company's failure to comply with the terms of the Hearings Panel's prior decision. Trading in the Company's ordinary shares was suspended at the open of trading on March 27, 2026. Trading in the Company's ordinary shares under the symbol "CMBMF" on the OTC Expert Market began on March 30, 2026. The Company has appealed this delisting determination.

The Company had previously received a deficiency letter from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) on April 10, 2025, notifying the Company that, it had failed to comply with the $1.00 per share minimum bid price requirement for continued inclusion on The Nasdaq Global Market pursuant to Nasdaq Listing Rule 5450(a)(1) (the “Bid Price Rule”). The Company received additional deficiency letters from the Staff on April 16, 2025, May 22, 2025, August 25, 2025 and November 25, 2025, notifying the Company that it was not in compliance with the requirements of Nasdaq Listing Rule 5250(c)(1) (the "Filing Rule") for failure to timely file its Form 10-K for the year ended December 31, 2024 and its Quarterly reports on Form 10-Q for the periods ended March 31, 2025, June 30, 2025 and September 30, 2025, respectively (the “Delinquent Filing”).

On November 11, 2025, the Company presented its plan of compliance before the Nasdaq Hearings Panel and requested a continued stay of its delisting pending achieving full compliance by filing the Delinquent Filings within the time requested under the plan of compliance. On December 3, 2025, the Company received a decision (the “Decision Letter”) from the Hearings Panel granting the Company’s request for continued listing of the Company’s ordinary shares, subject to the Company demonstrating compliance with the Bid Price Rule and the Filing Rule, on or before April 16, 2026, but subject to interim filing dates as set forth in the decision.

On December 12, 2025, the Company received a partial compliance letter from the Hearings Panel confirming the Company is in compliance with the Bid Price Rule, although it remained non-compliant with the Filing Rule.

On January 9, 2026, the Company received a further determination letter stating that because the Company did not hold an annual meeting of shareholders within twelve months from the Company's prior fiscal year end as required by Nasdaq Listing Rule 5620(a), the resulting non-compliance serves as an additional basis for delisting the Company's securities.

The Company was unable to meet the interim filing deadlines set forth in the Decision Letter, and requested extensions to the February 6, 2026 interim deadline, with additional extensions requested to March 16, 2026 and to March 23, 2026 were granted by the Hearing Panel.

Restructuring

Note 17. Restructuring

In 2023, the Company announced and initiated two corporate cost reductions plans, which included a reduction in the Company's workforce, with the first in August 2023 and the second in November 2023, to better align Cambium's cost structure with current economic conditions and position the Company to achieve near-term and long-term targets to maintain profitability, improve cash flow and maintain a strong balance sheet.

Under the November 2023 restructuring plan, as of December 31, 2023, the Company had a restructuring liability of $0.4 million which was included as Accrued liabilities on the Company's consolidated balance sheet. For the year ended December 31, 2024, the Company incurred an additional $1.1 million of costs, mostly for one-time termination costs, and paid $1.4 million, leaving a restructuring liability of $0.1 million as of December 31, 2024, which is included in Accrued liabilities in the Company's consolidated balance sheet. This amount was paid in the first quarter of 2025.

In February 2025, the Company announced another corporate cost reduction plan designed to reduce operating costs, including a reduction in the Company's workforce. The decision to execute the plan was made to better align Cambium's cost structure and business activities with the weaker market demand it has been experiencing and to take active measures to accelerate its margin recovery. Under the February 2025 restructuring plan, the Company incurred $1.8 million of costs, mostly related to one-time termination costs, all of which was paid by December 31, 2025.

The following table reflects the restructuring liability activity for the years ended December 31, 2024 and December 31, 2025 (in thousands):

For the years ended December 31, 2024 and 2025, the following table reflects the activity in the Company’s valuation allowance on deferred tax assets (in thousands):


	Years ended December 31,
	2024		2025

Beginning balance	$	38,611	$	50,956
Increase in valuation allowance		12,345		9,511

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences become deductible. The Company considers projected future taxable income, reversing taxable temporary differences, carryback opportunities, and tax-planning strategies in making this assessment.

As of each reporting date, management considers new evidence, both positive and negative, to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets before they otherwise expire. Cumulative losses are objective evidence that limit the ability to consider other subjective evidence such as the Company’s projections for future growth. The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as the Company’s projections for growth.

At December 31, 2024, the Company maintained a full valuation allowance of $51.0 million on its worldwide deferred tax assets. Due to continued losses in 2025, the Company continued to maintained its full valuation allowance position, which increased by $9.5 million, to $60.5 million, on its deferred tax assets as of December 31, 2025.

The actual tax costs may differ from the amounts recorded due to changes in tax laws, foreign exchange rates, and other factors, including the timing and manner of repatriation.

Goodwill and Intangible Assets

Note 5. Goodwill and intangible assets

The changes in the carrying amount of goodwill for the years ended December 31, 2024 and 2025 were as follows:


	December 31,			December 31,
	2024			2025
Beginning balance	$	9,842		$	874
Accumulated goodwill impairment		(8,968	)		—

The Company tests goodwill for impairment annually on December 31 and more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount and tests intangible assets if an indicator suggests that the carrying amount may not be recoverable.

During the third quarter of 2024, the Company experienced a debt covenant breach and a decline in its market capitalization as a result of a sustained decrease in the trading price of the Company's ordinary shares, each of which represented a triggering event causing management to perform a qualitative goodwill impairment test as of September 30, 2024. As a result of the impairment analysis, the Company recorded an impairment charge of $9.0 million against goodwill. The Company recorded this impairment as of September 30, 2024 and the loss is included in Impairment expense on the consolidated statements of operations and comprehensive loss for the year ended December 31, 2024.

As of December 31, 2024 and 2025, the Company's single reporting unit had a negative carrying value and no further goodwill impairment was recorded.

As part of the Company's review of its long-lived assets, the Company completed an assessment of its customer relationship intangible during the year ended December 31, 2024 to determine its fair value. The excess earnings method was utilized to value the customer relationships intangible. Based on the results of its assessment, the Company determined that fair value of its customer relationship intangible was negative and the entire value was impaired, resulting in an impairment loss of $6.6 million and the loss is included in Impairment expense on the consolidated statements of operations and comprehensive loss.

Intangible assets are amortized over their expected useful life and none are expected to have a significant residual value. The useful life, gross carrying value, accumulated amortization, and net balance for the Company's customer relationship intangible at December 31, 2024 was as follows (in thousands):


		December 31, 2024

	Useful Life	Gross carrying amount		Accumulated amortization			Impairment			Net balance

Customer relationships	5 to 18 years	$	19,300	$	(12,749	)	$	(6,551	)	$	—
Total		$	19,300	$	(12,749	)	$	(6,551	)	$	—

Intangible assets amortization expense was $1.1 million for the year ended December 31, 2024. As the intangible asset was fully impaired in 2024, there was no amortization expense recognized for the year ended December 31, 2025.

Amortization of acquired and internal use software is computed using the straight-line method over an estimated useful life of generally three to seven years. Amortization expense recognized on acquired and internal use software is reflected in depreciation and amortization in the consolidated statements of operations. Amortization expense was $0.4 million and $0.1 million for the years ended December 31, 2024 and 2025, respectively.

Amortization expense recognized on software to be marketed for external sale was $3.9 million and $3.2 million for the years ended December 31, 2024 and 2025, respectively, and is included in cost of revenues on the consolidated statements of operations.

As a result of the impairment triggers identified for the year ended December 31, 2024, the Company completed a quantitative assessment on the Company's long-lived assets for recoverability and recognized a $0.5 million impairment on its internal use software and is included in Impairment expense on the consolidated statement of operations. There was no further impairment recognized for the year ended December 31, 2025. As of December 31, 2025, the gross carrying amount of the acquired software and software for internal use reflect the impact of the impairment.

The Company completes the net realizable value test on its software to be marketed for external sale and compares the unamortized capitalized costs of each computer software product to its net realizable value of that product at each reporting period. The amount by which the unamortized capitalized costs of the computer software product exceeds the net realizable value of that assets shall be written off. The net realizable value was estimated using future gross revenues from that product and was reduced by the estimated future costs of completing and disposing of the product, including the costs of performing maintenance and customer support required to satisfy the Company's responsibility set forth at the time of sale. As a result of the net realizable value test, the Company identified one product for impairment and recognized a $0.6 million impairment as of December 31, 2024. For the year ended December 31, 2025, the Company identified an additional products for impairment and recognized a $0.2 million impairment as of December 31, 2025. These amounts are included in Impairment expense on the consolidated statement of operations and comprehensive loss.

Based on capitalized software assets at December 31, 2025, after recognition of the above noted impairment, estimated amortization expense in future fiscal years is as follows (in thousands):


Year ending December 31,	Acquired software and Software for internal use		Software marketed for external sale		Total

Employee benefit plans

Note 7. Employee benefit plans

The Company’s significant employee benefit plans currently consist of a defined contribution plan in the United States and a separate defined contribution plan in the UK. The Company does not offer any other elective postretirement benefit plans, such as retiree medical and dental benefits or deferred compensation agreements to its employees or officers.

U.S. plan

U.S. regular, full-time employees are eligible to participate in the Cambium Networks, Inc. 401(k) Plan, which is a qualified defined contribution plan under section 401(k) of the Internal Revenue Service Code. Under the Cambium Networks, Inc. 401(k) Plan, the Company contributes a dollar-for-dollar match of the first 4% an employee contributes to the plan. Employees are eligible to participate on the first day of the month following their date of hire and begin receiving company contributions three-months after they become eligible to participate in the plan. Company matching contributions are made each pay period, but the funds do not vest until the employee’s second anniversary of employment with the Company. Employees are always fully vested in their own contributions. All contributions, including the Company match, are made in cash and invested in accordance with the participants’ investment elections. Contributions made by the Company under the Cambium Networks, Inc. 401(k) Plan were $0.8 million and $0.9 million for the years ended December 31, 2024 and 2025, respectively.

UK plan

Regular, full-time UK employees are eligible to participate in the Cambium Networks Ltd. Stakeholder Pension Scheme, which is a qualified defined contribution plan. Employees are eligible to participate on the first of the month following receipt of their enrollment form, and eligible employees are automatically enrolled in the plan at a default employee contribution rate of 3% and a company contribution rate of 5% of the employee’s basic salary. The Company contribution rate increases by 1% for each additional 1% that the employee contributes up to a maximum of 7%. Company matching contributions vest immediately and employees are always vested in their own contributions. All contributions, including the Company match, are made in cash and deposited in the participant’s account each pay period. The total contributed by the Company under this plan was $0.4 million and $0.3 million for the years ended December 31, 2024 and 2025, respectively.

Description of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of Cambium Networks Corporation and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
Going Concern	Going Concern In accordance with the accounting guidance related to the presentation of financial statements, when preparing financial statements for each annual and interim reporting period, management evaluates whether there are conditions or events that, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In making its assessment, management considered the Company’s current financial condition and liquidity sources, including current funds available, forecasted future cash flows and conditional and unconditional obligations due over the next twelve months, as well as other factors including the markets in which the Company competes and the current customer demand for the Company’s products. As of December 31, 2025, the Company was not in compliance with its quarterly fixed charge coverage ratio and quarterly consolidated leverage ratio covenants. These defaults continue into 2026. Such defaults afford the lender the right to declare the amounts outstanding immediately due and payable, and although the Company continues regular discussions with the lender, it has not been able to obtain a waiver of the defaults, or otherwise refinance such indebtedness. If the lender were to accelerate the maturity of the Company's indebtedness under the Amended Credit Agreement, the Company would not be able to repay the debt, and therefore, there is substantial uncertainty the Company would be able to continue as a going concern. The Company’s obligations under the Amended Credit Agreement mature and become due and payable on November 17, 2026, absent acceleration by the lender. The Company ceased payment of principal and interest on the term loan and payment of interest under the revolving credit facility as of June, 2025. As the covenant violations afford the lender the right to declare the amounts outstanding immediately due and payable, the term loan facility and the associated deferred debt issuance costs and the revolving credit facility are classified as a current liability and the deferred debt issuance costs associated with the revolving credit facility are classified as a current asset in the accompanying consolidated balance sheet as of December 31, 2025. Please refer to Note 6. Debt, regarding the Company’s debt outstanding under its credit facilities with Bank of America. The Company continues to take actions to improve its profitability and focus on operating efficiency and reducing discretionary spending, deferring capital expenditures and implementing cost reductions to align its cost structure with current and expected revenue levels. Based on the Company’s current forecast, it is projecting future noncompliance with its financial covenants for the remainder of the term of the loan in addition to the covenant noncompliance described above. If the lender were to accelerate the maturity of the Company's indebtedness under the Amended Credit Agreement, there is substantial uncertainty the Company would be able to secure capital resources to repay the amounts due. Due to these uncertainties and given the debt matures on November 17, 2026, management concluded that substantial doubt exists with respect to the Company's ability to continue as a going concern within one year after the date that these consolidated financial statements are issued. The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.
Use of Accounting Estimates	Use of Accounting Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates these estimates, including those related to the provision for excess and obsolete inventory, the carrying amount of estimated inventory returns, the estimated amount expected to be refunded to customers in respect of inventory returns and customer rebates, estimate of the allowance for credit losses, estimate associated with the measurement of asset values for impairment, fair value of equity awards granted to employees and the associated forfeiture rates, leases, provision for income taxes, and recoverability of deferred tax assets. The Company bases estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.
Segments	Segments Management has determined that it operates as one operating segment as it only reports financial information on an aggregated and consolidated basis to its Chief Executive Officer, who is the Company’s chief operating decision maker ("CODM"). Decisions about resource allocation or operating performance assessments are not made below a total company level.
Recognition of revenues	Recognition of revenues Revenues consist primarily of revenues from the sale of hardware products. Revenues also include amounts for software products, extended warranty on hardware products and software subscription services. Substantially all products are sold through distributors and other channel partners, such as resellers and systems integrators. The Company recognizes revenue to reflect the transfer of control of promised products or services to a customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for products or services. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company considers orders placed by its customers, which in most cases are governed by master distributor agreements, or customer purchase orders to be the contracts with the customer. For each contract, the Company identifies its distinct performance obligations under each contract. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. Hardware products with essential embedded software, software products, extended warranty on hardware products and software subscriptions have been identified as separate performance obligations. The Company accounts for shipping and handling costs as fulfillment costs which are recorded in Cost of product revenues in the consolidated statement of operations. This includes shipping and handling costs incurred after control has transferred to the customer as the Company has elected the practical expedient in ASC Topic 606. The Company recognizes revenue when, or as, it satisfies a performance obligation when control of a promised product or service transfers to a customer. Revenue from hardware products with embedded software is typically recognized at the time of shipment, which is when the customer has the ability to direct the use of and obtain substantially all of the remaining benefit from the asset. Software revenue consists of perpetual license software and is recognized at the point in time the customer obtains control of the software and is able to use or benefit from the software. Extended warranty is available for purchase on hardware products and is a performance obligation that is satisfied over time, beginning on the effective date of the warranty term and ending on the expiration of the warranty term. The Company recognizes revenue on extended warranties on a straight-line basis over the warranty period. Revenue from subscription services is recognized ratably over the term in which the services are provided and our performance obligation is satisfied. The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring products or services to a customer. The Company allocates the transaction price to each performance obligation on a relative standalone selling price basis for each distinct product or service in the contract. The best evidence of standalone selling price is the observable price of a product or service when the Company sells that product or service separately in similar circumstances and to similar customers. If a standalone selling price is not directly observable, the Company estimates the transaction price allocated to each performance obligation using the expected costs plus a margin approach. In determining the transaction price, stock rotation rights and customer incentives are considered to be forms of variable consideration. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory and meets the definition of a right of return. Certain criteria must be met to rotate stock and the customer is also required to place an additional order. The Company estimates variable consideration for stock rotations using the value of inventory being held by its distributors ("channel inventory"), historical returns experience and a qualitative adjustment to consider fluctuations in ending channel inventory balance and actual returns being process in both historical and subsequent periods. The Company records a reduction to revenue at the selling price of the products expected to be returned and a liability for the estimated amount expected to be refunded to the customer as well as a reduction to costs of revenues and an asset at the cost of the estimated inventory to be returned. The Company also provides customer incentives in the form of rebates. The Company estimates variable consideration for rebates using the expected value method. The estimate incorporates all reasonably available information, including historical rebate experience, current channel inventory levels, macroeconomic indicators and observable changes in customer demand.
Cash	Cash The Company maintains cash balances at financial institutions that at times exceed federally insured limits. The Company has not experienced any losses on such accounts and believes it is not exposed to any significant credit risk on cash. Our cash consists primarily of U.S. dollar denominated demand accounts. Beginning in 2025, the Company has restricted cash for amounts used as collateral against the Company's purchasing card.
Receivables and concentration of credit risk	Receivables and concentration of credit risk Trade accounts receivable are recorded at invoiced amounts, net of the allowance for credit losses. The Company considers the credit risk of all customers and regularly monitors credit risk exposure in its trade receivables. The Company’s standard credit terms with their customers are generally net 30 to 60 days. The Company had one customer representing more than 10% of trade receivables at December 31, 2024 and at December 31, 2025. The Company had two customers representing more than 10% of revenues for the years ended December 31, 2024 and December 31, 2025. The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The allowance is determined by using the loss-rate method, which requires an estimation of loss rates based on historical loss experience adjusted for factors that are relevant to determining the expected collectability of accounts receivable. Some of these factors include macroeconomic conditions that correlate with historical loss experience, delinquency trends, aging behavior of receivables, and credit and liquidity indicators for individual customers.
Inventory	Inventory The Company’s inventories are primarily finished goods for resale and, to a lesser extent, raw materials. Inventories are stated at the lower of cost or net realizable value. In determining the cost of raw materials, consumables and goods purchased for resale, the average purchase price is used. For finished goods, cost is computed as production cost including capitalized inbound freight costs. The valuation of inventory also requires the Company to estimate excess or obsolete inventory. The determination of excess or obsolete inventory is based on a comparison of the quantity and cost of inventory on hand versus the Company's forecast of remaining lifetime demand, consideration of historical sales or usage and management's judgment. The Company also considers the rate at which new products will be accepted in the marketplace and how quickly customers will transition from older products to newer products. Any adjustments to the valuation of inventory are included in cost of revenues. The Company also records a liability for firm, noncancelable, and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of its future demand forecasts consistent with the valuation of its excess and obsolete inventory. Any adjustments to recognize a loss on supplier commitments are included in cost of revenues.
Property and equipment	Property and equipment Property and equipment is stated at cost less accumulated depreciation and impairment charges. The Company calculates depreciation expense using the straight-line method over the estimated useful lives of each asset based on its asset class. Leasehold improvements are amortized over the shorter of their useful lives or the lease term. See Note 3. Property and equipment for the useful lives for each asset class. Upon retirement or disposition, the asset cost and related accumulated depreciation are removed with any gain or loss recognized in operating expense in the consolidated statements of operations. For the years ended 2024 and 2025, the loss recognized was immaterial for any retirements or dispositions.
Software	Software Software may be purchased or developed internally for internal use. Costs are expensed as incurred during the preliminary project stage of an internal use software project and are capitalized once the project has been approved by management and is in the application development stage. Post implementation/operation costs, such as maintenance and training costs, are expensed as incurred. Any costs incurred to provide upgrades or enhancements are capitalized only if they provide additional functionality that did not previously exist. Amortization of internal use software begins when the software is ready for internal use and is amortized over its estimated useful life. The amortization expense for internal use software is computed using the straight-line method over three to seven years. Software may also be developed internally for external sale. Costs related to certain software available for sale are capitalized when the resulting product reaches technological feasibility. The Company generally determines technological feasibility when it has a detailed program design that takes product function, feature and technical requirements to their most detailed, logical form and the product is ready for coding. The Company does not typically capitalize costs related to the development of first-generation product offerings as technological feasibility generally coincides with general availability of the software. Amortization of software costs to be sold or marketed externally begins when the product is available for sale to customers and is amortized using the straight-line method over its estimated useful life of three years. For capitalized software costs related to software available for sale, the Company completes an impairment analysis at each reporting date comparing the net realizable value of any product to its net book value. See Note 4. Software for further details.
Impairment of long-lived assets	Impairment of long-lived assets The Company evaluates its long-lived assets, including property and equipment, internal-use software, right-of-use assets, and definite-lived intangible assets for impairment by completing a quarterly qualitative assessment and whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or asset group. If impairment is indicated, the asset is written down to its estimated fair value. See Notes 3. Property and equipment, Note 4. Software and Note 5. Goodwill and intangible assets and Note 15. Leases for further details.
Goodwill and intangible assets	Goodwill Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is measured at cost and is not amortized. Intangible assets acquired, either individually or with a group of assets, are initially recognized and measured at fair value. The Company uses third-party specialists to assist management to determine fair values and estimated useful lives for intangible assets acquired in business combinations. Intangible assets with finite useful lives are amortized on a straight-line basis over their estimated useful lives of between 3 and 18 years. The Company has no intangible assets with indefinite lives. The Company assesses goodwill for impairment at least annually on December 31 and whenever events or circumstances that would more likely than not, reduce the fair value below its carrying value. Annual impairment testing is completed at the reporting unit level. Management has concluded the Company operates as one reporting unit and one operating segment for annual impairment testing. In completing its impairment evaluations, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. In performing this qualitative assessment, the Company assesses relevant events and changes in circumstances, including industry and market conditions, operating results, business plans, and entity-specific events that would affect the fair value or the carrying amount of a reporting unit. If it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company determines the fair value of the reporting unit and compares the fair value to its carrying value. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired and no further steps are required.
Leases	Leases The Company has both cancelable and noncancelable operating leases for office space, vehicles, and office equipment. The Company records a right-of-use asset and lease liability on its consolidated balance sheet for all leases that qualify. The operating lease liability represents the present value of the future minimum lease payments over the lease term using either the rate implicit in the lease or the Company’s incremental borrowing rate at the lease commencement date. The right-of-use asset reflects adjustments for the derecognition of deferred rent and prepaid rent. Leases with an initial term of 12 months or less are not recorded on the Company’s consolidated balance sheet, and are expensed on a straight-line basis over the lease term. The Company does not include any renewal periods in the lease term for its leases as sufficient economic factors do not exist that would compel it to continue to use the underlying asset beyond the initial non-cancelable term. The Company has elected to combine the lease and non-lease components into a single lease component for all of its leases. See Note 15. Leases for further details.
Product warranties	Product warranties The Company provides a standard warranty on its products, with the term depending on the product, and records a liability for the estimated future costs associated with potential warranty claims. Provisions for warranty claims are recorded at the time products are sold based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. These provisions are reviewed and adjusted by management periodically to reflect actual and anticipated experience. The warranty costs are reflected in the Company’s consolidated statements of operations within cost of revenues. In certain circumstances, the Company may have recourse from its contract manufacturers for replacement cost of defective products, which it also factors into its warranty liability assessment.
Income taxes	Income taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in its financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement carrying amount and the tax basis of assets and liabilities using enacted income tax rates in effect for the year in which the differences are expected to be recovered or settled. The effect of a change in income tax rates on deferred tax assets and liabilities is recognized in the income tax provision in the period that includes the enactment date. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts the valuation allowances accordingly. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. As of December 31, 2024, conditions existed that raised substantial doubt about the Company's ability to continue as a going concern within one year after the date the financial statements are issued. As a result, the Company no longer asserts indefinite reinvestment with respect to earnings of foreign subsidiaries. Accordingly, the Company recorded a deferred tax liability for the outside basis difference of its foreign affiliates and estimated future tax consequences associated with the potential sale of its foreign investments, including applicable foreign withholding taxes and other incremental taxes. As of December 31, 2025, the Company maintains its position that it does not assert indefinite reinvestment on its undistributed earnings of its foreign subsidiaries. As a result, the Company increased the deferred tax liability for its outside basis difference of its foreign subsidiaries. The actual tax costs may differ from the amounts recorded due to changes in tax laws, foreign exchange rates, and other factors, including the timing and manner of repatriation. The Company may be subject to income tax audits in all of the jurisdictions in which it operates and, as a result, must also assess exposures to any potential issues arising from current or future audits of current and prior years’ tax returns. Accordingly, the Company must assess such potential exposures and, where necessary, provide for any expected loss. The Company would recognize the benefit of a tax position if it is more likely than not to be sustained. Recognized tax positions are measured at the largest amount more likely than not to be realized upon settlement. To the extent that the Company establishes a liability, its income tax expense would be increased. If the Company ultimately determines that payment of these amounts is unnecessary, it would reverse the liability and recognize an income tax benefit during the period in which new information becomes available indicating that the liability is no longer necessary. The Company would record an additional income tax expense in the period in which new information becomes available indicating that the income tax liability is greater than its original estimate. The Company did not record such an adjustment for the years ended December 31, 2024 or 2025.
Share-based compensation	Share-based compensation The Company accounts for share-based compensation by measuring and recognizing compensation expense for all share-based payments based on estimated grant date fair values for equity settled awards. The Company's policy is to recognize compensation expense on a straight-line basis over the requisite service period of the award, adjusted for an estimate of expected forfeitures. Awards are granted under the 2019 Share Incentive Plan. The 2019 Share Incentive Plan provides for the grant of incentive share options, nonqualified share options, share appreciation rights, restricted share awards, restricted share units, or other share-based awards and performance awards. The Company also issues shares under its Employee Share Purchase Plan ("ESPP"). The first offering period or purchase period under the ESPP began on January 1, 2021. The Company offers two offering periods of six months each per year. Under the ESPP, the purchase price of the Company's shares is 85% of the lower of the fair market value of the shares on the first trading date of each offering period or on the purchase date. Effective January 1, 2025, management has temporarily suspended the ESPP plan.
Contingencies	Contingencies The Company periodically evaluates all pending or threatened contingencies and any commitments, if any, that are reasonably likely to have a material adverse effect on its results of operations, financial position or cash flows. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.
Foreign currency translation	Foreign currency translation The reporting currency of the Company is the U.S. dollar and the functional currency for each operating subsidiary is the local currency of the operating subsidiary other than for Cambium Networks, Ltd. (UK) for which the functional currency is the U.S. dollar. Local currency denominated monetary assets and liabilities are translated at exchange rates in effect at the balance sheet date, and revenues, cost of revenues and expenses are translated at the average exchange rate in effect during the applicable period. The Company recognizes foreign exchange gains and losses in other expense on its consolidated statements of operations and accumulated other comprehensive income (loss) on its consolidated balance sheets.
Research and development costs	Research and development costs Research and development expenses consist primarily of salary and benefit expenses for employees and contractors engaged in research, design and development activities, and costs for prototypes, travel costs and shared facility and IT costs. The Company also incurs research and development costs associated with the development of software for both internal use and to be marketed externally. Research and development costs, other than those associated with the development of software that meet the criteria for capitalization, are expensed as incurred.
Recently adopted accounting standards and Recently issued accounting standards not yet adopted	Recently adopted accounting standards In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to disclose standard categories in the tax rate reconciliation, additional information for reconciling items that meet a quantitative threshold and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Adoption of this ASU should be applied prospectively, but may be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this ASU on a prospective basis for the year ended December 31, 2025. Refer to Note 12. Income Taxes, which reflects the incremental income tax disclosures. Recently issued accounting standards not yet adopted In October 2023, the FASB issued ASU 2023-06 Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission's ("SEC") Disclosure Update and Simplification Initiative. The amendments in this update require modification of certain disclosure and presentation requirements for a variety of ASU topics in response to the SEC's Release No. 33-10532. The effective date for each amended topic in the ASU is the date on which the SEC's removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendment will be removed from the Codification and not become effective. Early adoption is permitted. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures. In November 2024, the FASB issued 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses. The amendment requires disclosures of a) purchases of inventory, b) employee compensation, c) depreciation, d) intangible asset amortization and e) depreciation, depletion, and amortization recognized as part of oil-and gas-producing activities ("DD&A") included in each relevant expense caption. The amendment also requires that certain amounts that are already required to be disclosed under generally accepted accounting principles ("GAAP") be included in the same disclosure as the other disaggregation requirements. The new guidance also requires a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, this guidance may be applied prospectively or retrospectively to all prior periods presented. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures and expects the ASU will increase disclosures in the Company's annual and interim reporting when adopted.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Item 1C. Cybersecurity Cybersecurity Risk Management and Strategy Information about cybersecurity risks and our risk management processes is collected, analyzed and considered as part of our overall enterprise risk management program. Our cybersecurity program has been built around the National Institute of Standards and Technology (NIST) framework with flexibility to support our product development, deployment, operations, and monitoring. The NIST framework organizes cybersecurity risks into five categories: identify, protect, detect, respond and recover, with an emphasis on prevention, detection and mitigation. We have key Company policies that directly or indirectly relate to cybersecurity matters, including policies relating to antivirus protection, remote access, multifactor authentication, restricted access based upon business need and confidentiality of information, as well as procedures designed to reduce phishing, increase employee awareness of phishing attempts and other activities. The key elements of our efforts to identify, prevent, mitigate, and remediate cybersecurity risks and incidents through our cybersecurity risk management program include: • We collect and analyze information about cybersecurity risks as part of our risk management program and monitor and discuss public alerts, threat levels, trends and remediation. • All employees receive periodic cybersecurity training and are exposed to phishing simulations designed to educate concerning the recognition of cybersecurity threats. • We use various security tools, including internal reporting, monitoring, and bug bounty programs, to identify vulnerabilities in our products. • Regular system updates and patching are done to protect our hardware and software against security vulnerabilities. • We conduct simulations, drills, and penetration testing to test our defenses and monitor threat levels, including the periodic performance of simulations and tabletop exercises to test our policies, incorporating external resources and advisors as needed. • We have controls and procedures in place for prompt escalation of cybersecurity incidents and regularly evaluate and update contingency planning, including plans in the event that a portion of our information resources were to be unavailable due to a cybersecurity incident. • We partner with third-party security consultants to review our incident response process and ensure our programs align with industry standards. • We assess the cybersecurity preparedness of key vendors, review any reports on system and organizations controls, before onboarding and monitor their vulnerabilities, including any publicly reported vulnerabilities. This process includes risk assessments, security questionnaires, review of vendor security programs, review of available security assessments, reports, and audits. Depending on the nature of the services provided, the sensitivity of the information systems and data at issue, and the type of provider, our vendor management process may involve different levels of assessment designed to help identify cybersecurity risks associated with a provider and impose contractual obligations related to cybersecurity on the provider. • We have a cybersecurity risk insurance policy. Risk Assessment While we have not experienced any prior cybersecurity incidents that have materially affected us, including our operations, business strategy, results of operations, or financial condition, we experience cyber-attacks and other attempts to gain unauthorized access to our systems on a regular basis, and we anticipate continuing to be subject to such attempts. Despite our implementation of security measures, (i) our products and services, and (ii) the servers, data centers, and cloud-based solutions on which our and third-party data is stored, are vulnerable to cyber-attacks, data breaches, malware, and disruptions from unauthorized access, tampering or other theft or misuse, including by employees, malicious actors or inadvertent error. We face certain ongoing risks from cybersecurity threats that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See “Risk Factors -Cyber-attacks, data breaches or malware may disrupt our operations, harm our operating results and financial condition, and damage our reputation or otherwise materially harm our business; and cyber-attacks or data breaches on our customers’ networks, or in cloud-based services provided by or enabled by us, could result in claims of liability against us, damage our reputation or otherwise materially harm our business” and“-Vulnerabilities and critical security defects, prioritization decisions regarding remedying vulnerabilities or security defects, failure of third-party providers to remedy vulnerabilities or security defects, or customers not deploying security releases or deciding not to upgrade products, services or solutions could result in claims of liability against us, damage our reputation, or otherwise materially harm our business.” Cybersecurity Governance Cybersecurity risk is part of management's risk oversight, although periodic reports are made to the board of directors of management's implementation and monitoring of our cybersecurity risks programs.

Total depreciation expense was $4.2 million and $1.3 million for the years ended December 31, 2024 and 2025, respectively.

As a result of the impairment triggers identified during the year ended December 31, 2024, the Company completed a quantitative assessment on the Company's long-lived assets for recoverability. Based on the quantitative assessment performed, management concluded that the assets were not recoverable.

For the long-lived assets classified as property and equipment, including leasehold improvements on certain operating leases, the assets were valued using a cost approach. A replacement cost was estimated by applying age and asset-type specific indices to the assets' original cost. That replacement cost was then depreciated for physical wear and tear by applying a straight-line method with lives based on the book depreciation lives for property and equipment and internal use software, and lives based on the lesser of the physical life and the life of the property lease for leasehold improvements. The resulting depreciated replacement cost was then reduced further for economic obsolescence. After completing a business enterprise valuation, the Company determined that earnings were insufficient to support the values of the assets and an adjustment was made. As a result, the Company determined that the carrying values were higher than the computed fair values for most of the assets, resulting in an impairment loss of $8.8 million, consisting of $4.9 million for equipment and tooling, $3.2 million for leasehold improvements, $0.6 million for computer equipment and $0.1 million for furniture and fixtures. The Company recorded this impairment as of September 30, 2024 and the loss is included in Impairment expense on the consolidated statements of operations and comprehensive loss. There was no further impairment recognized for the year ended December 31, 2025. As of December 31, 2025, the costs of the assets reflect the impact of the impairment.

Description of Business and Summary of Significant Accounting Policies

Note 1. Description of Business and Summary of Significant Accounting Policies

Business

Cambium Networks Corporation (“Cambium” or “Cambium Networks” or the “Company”), incorporated under the laws of the Cayman Islands, is a holding company whose principal operating entities are Cambium Networks, Ltd. (UK), Cambium Networks, Inc. (USA), and Cambium Networks Private Limited (India). On June 26, 2019, the Company completed an Initial Public Offering and the Company's ordinary shares began trading on the Nasdaq Global Market. Trading in the Company's ordinary shares was suspended at the open of trading on March 27, 2026. Trading in the Company's ordinary shares under the symbol "CMBMF" on the OTC Experts Market began on March 30, 2026.

Cambium Networks Corporation and its wholly owned subsidiaries design, develop, and manufacture fixed wireless and PON/XGSPON based broadband, Wi-Fi, and local area networking ("LAN") switching infrastructure, and security gateway solutions for a wide range of applications, including broadband access, wireless backhaul, Internet of Things (IoT), public safety communication and Wi-Fi access. Cambium's products enable service providers, enterprises, industrial organizations and governments to deliver exceptional digital experiences and device connectivity, with compelling economics. The Company's ONE network platform simplifies the management of Cambium Networks' wired and wireless technologies. The Company's product lines fall into three broad, interrelated categories: Fixed Wireless and fiber Broadband ("FWB"), Enterprise Networking, and Subscriptions and Services.

The Company operates on a calendar year ending December 31. As such, all references to 2024 and 2025 contained within these notes relate to the calendar year, unless otherwise indicated.

Basis of Presentation

The Company’s consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of Cambium Networks Corporation and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.

Going Concern

In accordance with the accounting guidance related to the presentation of financial statements, when preparing financial statements for each annual and interim reporting period, management evaluates whether there are conditions or events that, when considered in the aggregate, raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In making its assessment, management considered the Company’s current financial condition and liquidity sources, including current funds available, forecasted future cash flows and conditional and unconditional obligations due over the next twelve months, as well as other factors including the markets in which the Company competes and the current customer demand for the Company’s products.

As of December 31, 2025, the Company was not in compliance with its quarterly fixed charge coverage ratio and quarterly consolidated leverage ratio covenants. These defaults continue into 2026. Such defaults afford the lender the right to declare the amounts outstanding immediately due and payable, and although the Company continues regular discussions with the lender, it has not been able to obtain a waiver of the defaults, or otherwise refinance such indebtedness. If the lender were to accelerate the maturity of the Company's indebtedness under the Amended Credit Agreement, the Company would not be able to repay the debt, and therefore, there is substantial uncertainty the Company would be able to continue as a going concern. The Company’s obligations under the Amended Credit Agreement mature and become due and payable on November 17, 2026, absent acceleration by the lender. The Company ceased payment of principal and interest on the term loan and payment of interest under the revolving credit facility as of June, 2025.

As the covenant violations afford the lender the right to declare the amounts outstanding immediately due and payable, the term loan facility and the associated deferred debt issuance costs and the revolving credit facility are classified as a current liability and the deferred debt issuance costs associated with the revolving credit facility are classified as a current asset in the accompanying consolidated balance sheet as of December 31, 2025. Please refer to Note 6. Debt, regarding the Company’s debt outstanding under its credit facilities with Bank of America.

The Company continues to take actions to improve its profitability and focus on operating efficiency and reducing discretionary spending, deferring capital expenditures and implementing cost reductions to align its cost structure with current and expected revenue levels.

Based on the Company’s current forecast, it is projecting future noncompliance with its financial covenants for the remainder of the term of the loan in addition to the covenant noncompliance described above. If the lender were to accelerate the maturity of the

Company's indebtedness under the Amended Credit Agreement, there is substantial uncertainty the Company would be able to secure capital resources to repay the amounts due. Due to these uncertainties and given the debt matures on November 17, 2026, management concluded that substantial doubt exists with respect to the Company's ability to continue as a going concern within one year after the date that these consolidated financial statements are issued.

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Use of Accounting Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates these estimates, including those related to the provision for excess and obsolete inventory, the carrying amount of estimated inventory returns, the estimated amount expected to be refunded to customers in respect of inventory returns and customer rebates, estimate of the allowance for credit losses, estimate associated with the measurement of asset values for impairment, fair value of equity awards granted to employees and the associated forfeiture rates, leases, provision for income taxes, and recoverability of deferred tax assets. The Company bases estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Segments

Management has determined that it operates as one operating segment as it only reports financial information on an aggregated and consolidated basis to its Chief Executive Officer, who is the Company’s chief operating decision maker ("CODM"). Decisions about resource allocation or operating performance assessments are not made below a total company level.

Recognition of revenues

Revenues consist primarily of revenues from the sale of hardware products. Revenues also include amounts for software products, extended warranty on hardware products and software subscription services. Substantially all products are sold through distributors and other channel partners, such as resellers and systems integrators.

The Company recognizes revenue to reflect the transfer of control of promised products or services to a customer in an amount that reflects the consideration to which the Company expects to be entitled in exchange for products or services.

The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company considers orders placed by its customers, which in most cases are governed by master distributor agreements, or customer purchase orders to be the contracts with the customer.

For each contract, the Company identifies its distinct performance obligations under each contract. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. Hardware products with essential embedded software, software products, extended warranty on hardware products and software subscriptions have been identified as separate performance obligations.

The Company accounts for shipping and handling costs as fulfillment costs which are recorded in Cost of product revenues in the consolidated statement of operations. This includes shipping and handling costs incurred after control has transferred to the customer as the Company has elected the practical expedient in ASC Topic 606.

The Company recognizes revenue when, or as, it satisfies a performance obligation when control of a promised product or service transfers to a customer. Revenue from hardware products with embedded software is typically recognized at the time of shipment, which is when the customer has the ability to direct the use of and obtain substantially all of the remaining benefit from the asset. Software revenue consists of perpetual license software and is recognized at the point in time the customer obtains control of the software and is able to use or benefit from the software. Extended warranty is available for purchase on hardware products and is a performance obligation that is satisfied over time, beginning on the effective date of the warranty term and ending on the expiration of the warranty term. The Company recognizes revenue on extended warranties on a straight-line basis over the warranty period. Revenue from subscription services is recognized ratably over the term in which the services are provided and our performance obligation is satisfied.

The transaction price is the amount of consideration to which the Company expects to be entitled in exchange for transferring products or services to a customer. The Company allocates the transaction price to each performance obligation on a relative standalone selling price basis for each distinct product or service in the contract. The best evidence of standalone selling price is the

observable price of a product or service when the Company sells that product or service separately in similar circumstances and to similar customers. If a standalone selling price is not directly observable, the Company estimates the transaction price allocated to each performance obligation using the expected costs plus a margin approach.

In determining the transaction price, stock rotation rights and customer incentives are considered to be forms of variable consideration. Stock rotation rights grant the distributor the ability to return certain specified amounts of inventory and meets the definition of a right of return. Certain criteria must be met to rotate stock and the customer is also required to place an additional order. The Company estimates variable consideration for stock rotations using the value of inventory being held by its distributors ("channel inventory"), historical returns experience and a qualitative adjustment to consider fluctuations in ending channel inventory balance and actual returns being process in both historical and subsequent periods. The Company records a reduction to revenue at the selling price of the products expected to be returned and a liability for the estimated amount expected to be refunded to the customer as well as a reduction to costs of revenues and an asset at the cost of the estimated inventory to be returned. The Company also provides customer incentives in the form of rebates. The Company estimates variable consideration for rebates using the expected value method. The estimate incorporates all reasonably available information, including historical rebate experience, current channel inventory levels, macroeconomic indicators and observable changes in customer demand.

Cash

The Company maintains cash balances at financial institutions that at times exceed federally insured limits. The Company has not experienced any losses on such accounts and believes it is not exposed to any significant credit risk on cash. Our cash consists primarily of U.S. dollar denominated demand accounts. Beginning in 2025, the Company has restricted cash for amounts used as collateral against the Company's purchasing card.

Receivables and concentration of credit risk

Trade accounts receivable are recorded at invoiced amounts, net of the allowance for credit losses. The Company considers the credit risk of all customers and regularly monitors credit risk exposure in its trade receivables. The Company’s standard credit terms with their customers are generally net 30 to 60 days. The Company had one customer representing more than 10% of trade receivables at December 31, 2024 and at December 31, 2025. The Company had two customers representing more than 10% of revenues for the years ended December 31, 2024 and December 31, 2025.

The Company establishes an allowance for credit losses to present the net amount of accounts receivable expected to be collected. The allowance is determined by using the loss-rate method, which requires an estimation of loss rates based on historical loss experience adjusted for factors that are relevant to determining the expected collectability of accounts receivable. Some of these factors include macroeconomic conditions that correlate with historical loss experience, delinquency trends, aging behavior of receivables, and credit and liquidity indicators for individual customers.

Inventory

The Company’s inventories are primarily finished goods for resale and, to a lesser extent, raw materials. Inventories are stated at the lower of cost or net realizable value. In determining the cost of raw materials, consumables and goods purchased for resale, the average purchase price is used. For finished goods, cost is computed as production cost including capitalized inbound freight costs.

The valuation of inventory also requires the Company to estimate excess or obsolete inventory. The determination of excess or obsolete inventory is based on a comparison of the quantity and cost of inventory on hand versus the Company's forecast of remaining lifetime demand, consideration of historical sales or usage and management's judgment. The Company also considers the rate at which new products will be accepted in the marketplace and how quickly customers will transition from older products to newer products. Any adjustments to the valuation of inventory are included in cost of revenues.

The Company also records a liability for firm, noncancelable, and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of its future demand forecasts consistent with the valuation of its excess and obsolete inventory. Any adjustments to recognize a loss on supplier commitments are included in cost of revenues.

Property and equipment

Property and equipment is stated at cost less accumulated depreciation and impairment charges. The Company calculates depreciation expense using the straight-line method over the estimated useful lives of each asset based on its asset class. Leasehold improvements are amortized over the shorter of their useful lives or the lease term. See Note 3. Property and equipment for the useful lives for each asset class.

Upon retirement or disposition, the asset cost and related accumulated depreciation are removed with any gain or loss recognized in operating expense in the consolidated statements of operations. For the years ended 2024 and 2025, the loss recognized was immaterial for any retirements or dispositions.

Software

Software may be purchased or developed internally for internal use. Costs are expensed as incurred during the preliminary project stage of an internal use software project and are capitalized once the project has been approved by management and is in the application development stage. Post implementation/operation costs, such as maintenance and training costs, are expensed as incurred. Any costs incurred to provide upgrades or enhancements are capitalized only if they provide additional functionality that did not previously exist.

Amortization of internal use software begins when the software is ready for internal use and is amortized over its estimated useful life. The amortization expense for internal use software is computed using the straight-line method over three to seven years.

Software may also be developed internally for external sale. Costs related to certain software available for sale are capitalized when the resulting product reaches technological feasibility. The Company generally determines technological feasibility when it has a detailed program design that takes product function, feature and technical requirements to their most detailed, logical form and the product is ready for coding. The Company does not typically capitalize costs related to the development of first-generation product offerings as technological feasibility generally coincides with general availability of the software.

Amortization of software costs to be sold or marketed externally begins when the product is available for sale to customers and is amortized using the straight-line method over its estimated useful life of three years.

For capitalized software costs related to software available for sale, the Company completes an impairment analysis at each reporting date comparing the net realizable value of any product to its net book value. See Note 4. Software for further details.

Impairment of long-lived assets

The Company evaluates its long-lived assets, including property and equipment, internal-use software, right-of-use assets, and definite-lived intangible assets for impairment by completing a quarterly qualitative assessment and whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or asset group. If impairment is indicated, the asset is written down to its estimated fair value. See Notes 3. Property and equipment, Note 4. Software and Note 5. Goodwill and intangible assets and Note 15. Leases for further details.

Goodwill

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Goodwill is measured at cost and is not amortized. Intangible assets acquired, either individually or with a group of assets, are initially recognized and measured at fair value. The Company uses third-party specialists to assist management to determine fair values and estimated useful lives for intangible assets acquired in business combinations. Intangible assets with finite useful lives are amortized on a straight-line basis over their estimated useful lives of between 3 and 18 years. The Company has no intangible assets with indefinite lives.

The Company assesses goodwill for impairment at least annually on December 31 and whenever events or circumstances that would more likely than not, reduce the fair value below its carrying value.

Annual impairment testing is completed at the reporting unit level. Management has concluded the Company operates as one reporting unit and one operating segment for annual impairment testing.

In completing its impairment evaluations, the Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill. In performing this qualitative assessment, the Company assesses relevant events and changes in circumstances, including industry and market conditions, operating results, business plans, and entity-specific events that would affect the fair value or the carrying amount of a reporting unit. If it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company determines the fair value of the reporting unit and compares the fair value to its carrying value. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired and no further steps are required.

Leases

The Company has both cancelable and noncancelable operating leases for office space, vehicles, and office equipment. The Company records a right-of-use asset and lease liability on its consolidated balance sheet for all leases that qualify. The operating lease liability represents the present value of the future minimum lease payments over the lease term using either the rate implicit in the lease or the Company’s incremental borrowing rate at the lease commencement date. The right-of-use asset reflects adjustments for the derecognition of deferred rent and prepaid rent. Leases with an initial term of 12 months or less are not recorded on the Company’s consolidated balance sheet, and are expensed on a straight-line basis over the lease term. The Company does not include any renewal periods in the lease term for its leases as sufficient economic factors do not exist that would compel it to continue to use the underlying asset beyond the initial non-cancelable term. The Company has elected to combine the lease and non-lease components into a single lease component for all of its leases. See Note 15. Leases for further details.

Product warranties

The Company provides a standard warranty on its products, with the term depending on the product, and records a liability for the estimated future costs associated with potential warranty claims. Provisions for warranty claims are recorded at the time products are sold based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. These provisions are reviewed and adjusted by management periodically to reflect actual and anticipated experience. The warranty costs are reflected in the Company’s consolidated statements of operations within cost of revenues. In certain circumstances, the Company may have recourse from its contract manufacturers for replacement cost of defective products, which it also factors into its warranty liability assessment.

Income taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in its financial statements. Under this method, deferred tax assets and liabilities are determined on the basis of the differences between the financial statement carrying amount and the tax basis of assets and liabilities using enacted income tax rates in effect for the year in which the differences are expected to be recovered or settled. The effect of a change in income tax rates on deferred tax assets and liabilities is recognized in the income tax provision in the period that includes the enactment date.

In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized and adjusts the valuation allowances accordingly. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations.

As of December 31, 2024, conditions existed that raised substantial doubt about the Company's ability to continue as a going concern within one year after the date the financial statements are issued. As a result, the Company no longer asserts indefinite reinvestment with respect to earnings of foreign subsidiaries. Accordingly, the Company recorded a deferred tax liability for the outside basis difference of its foreign affiliates and estimated future tax consequences associated with the potential sale of its foreign investments, including applicable foreign withholding taxes and other incremental taxes. As of December 31, 2025, the Company maintains its position that it does not assert indefinite reinvestment on its undistributed earnings of its foreign subsidiaries. As a result, the Company increased the deferred tax liability for its outside basis difference of its foreign subsidiaries. The actual tax costs may differ from the amounts recorded due to changes in tax laws, foreign exchange rates, and other factors, including the timing and manner of repatriation.

The Company may be subject to income tax audits in all of the jurisdictions in which it operates and, as a result, must also assess exposures to any potential issues arising from current or future audits of current and prior years’ tax returns. Accordingly, the Company must assess such potential exposures and, where necessary, provide for any expected loss. The Company would recognize the benefit of a tax position if it is more likely than not to be sustained. Recognized tax positions are measured at the largest amount more likely than not to be realized upon settlement. To the extent that the Company establishes a liability, its income tax expense would be increased. If the Company ultimately determines that payment of these amounts is unnecessary, it would reverse the liability and recognize an income tax benefit during the period in which new information becomes available indicating that the liability is no longer necessary. The Company would record an additional income tax expense in the period in which new information becomes available indicating that the income tax liability is greater than its original estimate. The Company did not record such an adjustment for the years ended December 31, 2024 or 2025.

Share-based compensation

The Company accounts for share-based compensation by measuring and recognizing compensation expense for all share-based payments based on estimated grant date fair values for equity settled awards. The Company's policy is to recognize compensation expense on a straight-line basis over the requisite service period of the award, adjusted for an estimate of expected forfeitures.

Awards are granted under the 2019 Share Incentive Plan. The 2019 Share Incentive Plan provides for the grant of incentive share options, nonqualified share options, share appreciation rights, restricted share awards, restricted share units, or other share-based awards and performance awards.

The Company also issues shares under its Employee Share Purchase Plan ("ESPP"). The first offering period or purchase period under the ESPP began on January 1, 2021. The Company offers two offering periods of six months each per year. Under the ESPP, the purchase price of the Company's shares is 85% of the lower of the fair market value of the shares on the first trading date of each offering period or on the purchase date. Effective January 1, 2025, management has temporarily suspended the ESPP plan.

Contingencies

The Company periodically evaluates all pending or threatened contingencies and any commitments, if any, that are reasonably likely to have a material adverse effect on its results of operations, financial position or cash flows. Liabilities for loss contingencies arising from claims, assessments, litigation, fines, penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

Foreign currency translation

The reporting currency of the Company is the U.S. dollar and the functional currency for each operating subsidiary is the local currency of the operating subsidiary other than for Cambium Networks, Ltd. (UK) for which the functional currency is the U.S. dollar. Local currency denominated monetary assets and liabilities are translated at exchange rates in effect at the balance sheet date, and revenues, cost of revenues and expenses are translated at the average exchange rate in effect during the applicable period. The Company recognizes foreign exchange gains and losses in other expense on its consolidated statements of operations and accumulated other comprehensive income (loss) on its consolidated balance sheets.

Research and development costs

Research and development expenses consist primarily of salary and benefit expenses for employees and contractors engaged in research, design and development activities, and costs for prototypes, travel costs and shared facility and IT costs. The Company also incurs research and development costs associated with the development of software for both internal use and to be marketed externally. Research and development costs, other than those associated with the development of software that meet the criteria for capitalization, are expensed as incurred.

Recently adopted accounting standards

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to disclose standard categories in the tax rate reconciliation, additional information for reconciling items that meet a quantitative threshold and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. Adoption of this ASU should be applied prospectively, but may be applied retrospectively to all prior periods presented in the financial statements. The Company adopted this ASU on a prospective basis for the year ended December 31, 2025. Refer to Note 12. Income Taxes, which reflects the incremental income tax disclosures.

Recently issued accounting standards not yet adopted

In October 2023, the FASB issued ASU 2023-06 Disclosure Improvements: Codification Amendments in Response to the Securities and Exchange Commission's ("SEC") Disclosure Update and Simplification Initiative. The amendments in this update require modification of certain disclosure and presentation requirements for a variety of ASU topics in response to the SEC's Release No. 33-10532. The effective date for each amended topic in the ASU is the date on which the SEC's removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective. However, if by June 30, 2027, the SEC has not removed the related disclosure from its regulations, the amendment will be removed from the Codification and not become effective. Early adoption is permitted. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures.

In November 2024, the FASB issued 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) Disaggregation of Income Statement Expenses. The amendment requires disclosures of a) purchases of inventory, b) employee compensation, c) depreciation, d) intangible asset amortization and e) depreciation, depletion, and amortization recognized as part of oil-and gas-producing activities ("DD&A") included in each relevant expense caption. The amendment also requires that certain amounts that are already required to be disclosed under generally accepted accounting principles ("GAAP") be included in the same disclosure as the other disaggregation requirements. The new guidance also requires a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments are effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, this guidance may be applied prospectively or retrospectively to all prior periods presented. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures and expects the ASU will increase disclosures in the Company's annual and interim reporting when adopted.

Earnings Per Share [Abstract]

Loss per share

Note 10. Loss per share

Basic net earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares outstanding during the period. Diluted net earnings (loss) per share is computed by giving effect to all potentially dilutive ordinary share equivalents outstanding for the period. For purposes of this calculation, share options, RSUs, and ESPP awards are considered to be ordinary share equivalents but are excluded from the calculation of diluted earnings (loss) per share when including them would have an anti-dilutive effect. Performance-based share awards are only included in the calculation of diluted earnings (loss) per share if the performance metric would have been achieved as of December 31, 2025 if that had been the end of the contingency period. The following table sets forth the computation of basic and diluted net loss per share (in thousands, except for share and per share data):


	Year Ended December 31,
	2024			2025

Numerator:
Net loss	$	(74,452	)	$	(38,538	)

Net loss per share, basic	$	(2.65	)	$	(1.34	)
Net loss per share, diluted	$	(2.65	)	$	(1.34	)

In the computation of diluted loss per share for the years ended December 31, 2023 and 2024, no ordinary share equivalents were excluded because their inclusion would have been antidilutive.

Additionally, the Second Amendment provided that, during the Covenant Relief Period, (x) the Applicable Rate of interest being incurred on any outstanding Loans is increased to 3.25% per annum for Term SOFR Loans and 2.25% per annum for Base Rate Loans, (y) the commitment fee for undrawn commitments is increased to 0.35% and (z) the ability of the Loan Parties to make certain Investments, Dispositions and Restricted Payments, in each case, as more fully set forth in the Amended Credit Agreement.

At December 31, 2025, the applicable margin was 2.25% and the effective interest rate on the term loan facility was 9.45%. The weighted-average interest rate on the revolving credit facility was 9.23% for the year ended December 31, 2024. In addition to the interest charged on the term loan facility and the revolving credit facility, as a result of the covenant violations, the bank converted the term loan and revolving credit facilities to Base Rate loans on the default date and has imposed an additional 2% interest penalty on all outstanding amounts until the events of default are cured.

The maturity date of the term loan facility and the revolving credit facility, with all amounts outstanding becoming due and payable in full, is November 17, 2026.

Obligations under the Second Amendment are guaranteed by the Loan Parties and secured by Collateral, in each case, as set forth in the Existing Credit Agreement, including a lien on all assets owned by the Borrower (subject to agreed security principles, but providing for a customary qualifying floating charge over all of the Company's assets, with certain customary exceptions). The Second Amendment also required the Borrower and its Subsidiaries to transition certain of their primary principal disbursement services, payroll services and primary operating customer deposit services to Bank of America, N.A.

Loan covenants and violations

The Amended Credit Agreement is subject to financial covenants, including covenants which require the Company to meet key financial ratios and customary affirmative and negative covenants. Beginning in September 2024 and continuing through December 31, 2025, the Company was not in compliance with its financial covenants. In addition, the Company ceased payment of required quarterly principal and interest on the term loan facility and periodic interest on the revolving credit facility as of June 2025, providing an additional payment default under the Amended Credit Agreement. As the covenant violations give the lender the right to require immediate repayment of the amounts outstanding, the entire $21.5 million outstanding on the term loan facility and the $45.0 million outstanding under the revolving credit facility are classified as current and included in Current portion of long-term debt, net on the consolidated balance sheets as of December 31, 2025. Further, the $0.1 million of unamortized debt issuance cost associated with the term loan facility is classified as current and included in Current portion of long-term debt, net and $0.2 million of unamortized debt issuance costs associated with the revolving credit facility is classified as current and included in Other current assets on the consolidated balance sheets as of December 31 2025. If the lender requires immediate repayment of the outstanding term loan facility and revolving credit facility, the Company would be required to write-off the unamortized debt issuance costs upon extinguishment of the debt.

Although such defaults afford the lender the right to declare the amounts outstanding immediately due and payable, the Company continues to have regular discussions with the lender to obtain a waiver of the defaults, or otherwise refinance the indebtedness. There can be no assurances that the lender will provide a waiver and could declare the Company in default and accelerate all amounts due under the term loan facility and the revolving credit facility.

Interest expense, net

Net Interest expense, including bank charges and amortization of debt issuance costs, was $5.8 million and $9.0 million for the years ended December 31, 2024 and 2025, respectively. The increase in interest expense is primarily due to the addition of interest on the revolving credit facility against amounts borrowed in the first half of 2024, an increase in the interest rate due to the events of default noted above, the 2% penalty assessed against both the term facility and the revolving credit facility due to the events of default and a reduction of interest income due to the lower cash balances. For the year ended December 31, 2024, the Company expensed $0.6 million of fees related to an aborted amendment to our secured credit agreement.

- Definition

Leases

12 Months Ended

Dec. 31, 2025

Leases [Abstract]

Leases

Note 15. Leases

The Company has operating leases for offices, vehicles, and office equipment. Leases with a term of 12 months or less are not recorded on the consolidated balance sheets, and are expensed on a straight-line basis over the lease term.

Right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company’s lease payments are typically fixed or contain fixed escalators. The Company’s leases typically include certain lock-in periods and renewal options to extend the lease, but when determining the lease term, the Company does not consider options to extend a lease it is not reasonably certain to exercise. The Company elected the practical expedient to not separate the lease and non-lease components of its leases and currently has no leases with options to purchase the leased property.

The components of lease expense were as follows (in thousands):


	Year Ended December 31,
		2024		2025
Operating lease cost		$	2,315	$	1,976
Short-term lease cost			301		306
Variable lease costs			733		570
Total lease expense		$	3,349	$	2,852

Supplemental balance sheet information related to leases were as follows (in thousands, except lease term and discount rate):


	Balance Sheet Caption	December 31, 2024			December 31, 2025
Operating leases:
Operating lease assets	Operating lease assets	$	6,254		$	5,650
Current lease liabilities	Other current liabilities	$	1,232		$	863
Noncurrent lease liabilities	Noncurrent operating lease liabilities	$	8,942		$	8,785
Weighted average remaining lease term (years):
Operating leases			9.69			9.40
Weighted average discount rate:
Operating leases			7.03	%		7.29	%

For the year ended December 31, 2024, as part of the Company's impairment review of its long-lived assets, the Company completed a review of is right-of-use operating assets. The income approach was used to determine the fair value of the operating lease right-of-use assets. Current market rents were calculated by investigating the market for lease rates for facilities comparable to the subject properties. The market rents, less any incentives received, are the net effective market rents. The net effective market rents were projected through the end of the current terms for each location and discounted back to present value using a real estate rate of return based on the property to determine the fair values of each location. These fair values were then compared to the carrying value of the operating lease right-of-use asset values as of September 30, 2024. The carrying value was higher than the computed fair value for five of the eleven locations, resulting in a total impairment of $0.1 million. The Company recorded this impairment as of September 30, 2024 and the loss is included in Impairment expense on the consolidated statements of operations and comprehensive loss for the year ended December 31, 2024. There was no further impairment recognized for the year ended December 31, 2025.

Supplemental cash flow information related to leases were as follows (in thousands):


	Years Ended December 31,

Shareholders' equity

Note 9. Shareholders' equity

Ordinary Shares

As of December 31, 2024 and December 31, 2025, the Company's articles of association authorized the Company to issue up to 500,000,000 ordinary shares. Each holder of the Company's ordinary shares is entitled to one vote for each share on all matters submitted to a vote of the shareholders, including the election of directors.

As of December 31, 2025, no dividends have been declared or paid.

2019 Share incentive plan

In June 2019, the Company’s Board of Directors adopted, and its shareholders approved, the 2019 Share Incentive Plan (“2019 Plan”). The 2019 Plan provides for the grant of incentive share options, nonqualified share options, share appreciation rights, restricted share awards (“RSAs”), restricted share units (“RSUs”), other share-based awards and performance awards. The share reserve under the 2019 Plan will be automatically increased on the first day of each fiscal year, beginning with the fiscal year ended December 31, 2020 and will continue until, and including, the fiscal year ending December 31, 2029. The number of shares added annually will be equal to the lowest of 1,320,000 shares, 5% of the number of the Company’s shares outstanding on the first day of such fiscal year, or an amount determined by the Board of Directors. On March 1, 2023, the Company registered 1,320,000 additional shares that may be issued under the 2019 plan. On March 18, 2024 the Company registered 1,320,000 additional shares that may be issued under the 2019 Plan. The Company added 1,320,000 shares to the 2019 Plan as of January 1, 2025, under this provision. Due to the Company's noncompliance with Nasdaq Listing Rule 5250(c)(1) (the "Filing Rule") for failure to timely file its Form 10-K for the year ended December 31, 2024, the Company was not able to register these additional shares during 2025 to be issued under the 2019 Plan.

The Company’s employees, officers, directors, consultants, and advisors are eligible to receive awards under the 2019 Plan. Incentive share options, however, may only be granted to its employees.

The following table summarizes changes in the number of shares available for grant under the Company’s equity incentive plan during the years ended December 31, 2024 and December 31, 2025:


	Number of shares

Available for grant at December 31, 2023		1,748,352
Added to 2019 Share Incentive Plan		1,320,000
RSUs granted		(1,044,920	)
Options granted		(1,475,625	)
Shares withheld in settlement of taxes and/or exercise price		12,735
Expirations		330,598
Forfeitures		585,127
Available for grant at December 31, 2024		1,476,267
Added to 2019 Share Incentive Plan		1,320,000
Shares withheld in settlement of taxes and/or exercise price		137,441
Expirations		248,992
Forfeitures		381,368
Available for grant at December 31, 2025		3,564,068

The Company expects to satisfy the exercise of share options and future distributions of shares for restricted share units and restricted share awards by issuing new ordinary shares which have been reserved under the 2019 Plan.

The Company uses the Black-Scholes option pricing model to estimate the fair value of share options. The Company utilized a forfeiture rate of 11.4% for the years ended December 31, 2024 and December 31, 2025 for estimating the forfeitures of share options and restricted share units granted.

Share options

Share options typically have a contractual term of ten years from grant date. The following is a summary of option activity for the Company’s share incentive plans for year ended December 31, 2025:


	Options			Weighted average exercise price		Weighted Average remaining contractual term (years)		Aggregate intrinsic value
Outstanding at December 31, 2024		5,418,312		$	9.70		7.2	$	—
Options granted		—		$	—		—	$	—
Options exercised		—		$	—		—	$	—
Options expired		(248,992	)	$	9.67		—	$	—
Options forfeited		(230,323	)	$	4.31		—	$	—
Outstanding at December 31, 2025		4,938,997		$	9.95		6.1	$	—
Options exercisable at December 31, 2025		3,662,554		$	11.27		5.4	$	—
Options vested and expected to vest at December 31, 2025		4,886,418		$	10.01		6.0

The intrinsic value for share options outstanding and exercisable is defined as the difference between the market value of the Company’s ordinary shares as of the end of the period and the grant price. At December 31, 2024 and 2025, the aggregate intrinsic value of options exercisable under the Company’s share incentive plans was $0.0 million and $0.0 million, respectively, as determined as of the date of grant. The Company had no options exercised during the years ended December 31, 2024 and 2025.

At December 31, 2025, there was $4.7 million in unrecognized pre-tax share-based compensation expense, net of estimated forfeitures, related to unvested time-based share option awards. The unrecognized share-based compensation expense is expected to be recognized over a weighted-average period of 1.7 years.

Restricted shares

The following is a summary of restricted share activity for the Company’s share incentive plans for the year ended December 31, 2025:


	Units			Weighted average grant date fair value
RSU balance at December 31, 2024 1		1,263,210		$	5.29
RSUs granted		—		$	—
RSUs vested		(468,374	)	$	6.56
RSUs forfeited 1		(151,045	)	$	7.03
RSU balance at December 31, 2025		643,791		$	3.95

1 Includes the time-based RSUs and the performance-based RSUs for which a grant date has been established, as described below.

During 2024 and 2025, 1,044,920 and 0 RSUs were granted under the 2019 Plan, respectively. The Company withheld 12,735 and 137,441 shares to pay the employees’ portion of the minimum payroll withholding taxes on the RSUs that vested in 2024 and 2025, respectively.

At December 31, 2025, there was $2.1 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to unvested time-based share awards. The unrecognized compensation expense is expected to be recognized over a weighted average period of 1.9 years.

Performance-based share awards

In May 2023, performance-based share awards were awarded to select executive officers of the Company. The awards contained a performance-based vesting criteria and included 60,000 share options and 135,000 restricted share units. The performance-based awards had two separate annual performance periods, with 50% of the performance-based awards vesting over each of the annual performance periods ended December 31, 2023 ("First Performance Period") and December 31, 2024 ("Second Performance Period") if the performance goal was met. If the performance goal for that performance period was not met, the performance-based awards did not vest and were forfeited. The performance goal was based on the Company's adjusted earnings per share, as publicly reported by the Company, for each performance period. The method used to measure the fair value of the performance-based awards is consistent with the methods and assumptions used to measure the fair value of time-based share options and RSUs, as described above.

For performance-based awards that vest during the First Performance Period, the Company's Compensation Committee retained the ability to modify the applicable adjusted earnings per share metric. Due to this discretion, the Company determined that the grantee does not have a mutual understanding of the key terms and conditions of the performance-based awards in the First Performance Period, and a grant date will not exist until the Compensation Committee approves the adjusted earnings per share metric for the First Performance Period. As of December 31, 2023, based on the total potential shares that could be earned, there were 62,500 RSUs outstanding for which there is no accounting grant date. Accordingly, no grant date fair value was established and the weighted average grant date fair values calculated above excludes these performance-based share options and performance-based RSUs. The Company remeasured the fair value of the awards at each reporting date until a grant date is achieved, as the service inception date precedes the grant date. As of December 31, 2023, there was $0.4 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to unvested performance-based share awards for the First Performance Period, which would have been potentially recognized through the first quarter of 2024 upon achievement of the performance goal. As the performance goal was not met for 2023, 62,500 shares were forfeited as of January 29, 2024.

Unlike the performance-based awards in the First Performance Period, the Compensation Committee did not have the discretion to modify the applicable adjusted earnings per share metric for performance-based awards that vest during the Second Performance Period. As such, a mutual understanding of the key terms and conditions, and thus a grant date, existed on the date that the performance-based awards were issued by the Company. As of December 31, 2023, based on the total potential shares that could be earned, there were 62,500 RSUs granted. A grant date fair value was established, and the weighted average grant date fair values calculated in the above tables include these performance-based share options and performance-based RSUs. The Company has not recognized any compensation expense on these performance-based awards since the achievement of the performance goal was not probable. As of December 31, 2024, there was $0.5 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to these unvested performance-based share awards for the Second Performance Period. As the performance goal was not met for 2024, 37,500 shares were forfeited as of February 4, 2025.

Employee share purchase plan

In June 2019, the Company’s Board of Directors adopted, and its shareholders approved, the Employee Share Purchase Plan (“ESPP”). The ESPP was effective on June 25, 2019 and the offering period or purchase period under the ESPP began on January 1, 2021. A total of 1,334,427 shares are available under the ESPP, which includes 550,000 shares originally available, 256,730 additional shares registered on March 24, 2020, 260,345 additional shares registered on March 1, 2021, 267,352 additional shares registered on February 25, 2022, 273,133 additional shares registered on March 1, 2023 and 275,000 additional shares registered on March 18, 2024. The number of shares that will be available for sale under the ESPP will be increased annually on the first day of each fiscal year beginning in 2020, and will be equal to the lowest of: 275,000 shares; 1% of the outstanding shares as of the last day of the immediately preceding fiscal year, or such other amount as the administrator may determine. The purchase price of the shares will be 85% of the lower of the fair market value of our shares on the first trading day of each offering period or on the purchase date.
