Basis of Presentation and Restatement of previously issued unaudited consolidated financial statements

The unaudited consolidated financial statements include the accounts of Cambium Networks Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The consolidated financial statements as of March 31, 2025, and for the three-month periods ended March 31, 2024 and 2025, and the related notes are unaudited. The unaudited consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements, and, in the opinion of management, reflect all adjustments, which comprise only normal recurring adjustments necessary to state fairly the Company’s financial position as of March 31, 2025 and results of operations for the three-month periods ended March 31, 2024 and 2025 and cash flows for the three-month periods ended March 31, 2024 and 2025. The consolidated balance sheet as of December 31, 2024 has been derived from the audited financial statements at that date.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been condensed or omitted. The consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and related notes thereto for the year ended December 31, 2024 included in the Company’s Comprehensive Form 10-K filed with the SEC on April 7, 2026. The results of operations for the three-month period ended March 31, 2025 are not necessarily indicative of the operating results to be expected for the full year.

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 March 31, 2025, the Company was not in compliance with its quarterly fixed charge coverage ratio and quarterly consolidated leverage ratio covenants. These defaults continue through the remainder of 2025 and 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. As of March 31, 2025, the Company has made all required principal and interest payment obligations under the Amended Credit Agreement. Beginning in June 2025, the Company ceased making payment of principal and interest on the term loan and payment of interest on the revolving credit facility.

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 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 sheets as of December 31, 2024 and March 31, 2025. Please refer to Note 7. 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 through maturity of the debt 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 that 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.

Update to Significant Accounting Policies

There have been no material changes to the Company’s significant accounting policies disclosed in the 2024 Form 10-K, Part II, Item 8.

Recently issued accounting standards not yet adopted

In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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 plans to adopt this ASU on a prospective basis during the year ended December 31, 2025. The adoption of this standard will not have a material impact on the Company's consolidated financial statements, but will result in incremental income tax disclosures.

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 ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) -Disaggregation of Income Statement Expenses, which requires public entities to disclose within the footnotes to the financial statements, disaggregated information about certain income statement expense captions, including disclosure of the amounts included in each relevant expense caption. The amendment also requires that certain amounts that are already required to be disclosed under U.S. 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. ASU 2024-03 is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, this guidance should be applied prospectively, but may be applied retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the adoption of this standard on the Company's financial statement disclosures.

Note 2. Restatement of previously issued unaudited interim consolidated financial statements

In connection with the preparation of its consolidated financial statements for the year ended December 31, 2024, the Company determined that its previously issued unaudited interim consolidated financial statements for the three-month period ended March 31, 2024 contained errors in the application of GAAP. The Company evaluated the corrections and determined that the related impacts were material to the previously filed unaudited interim consolidated financial statements and in consultation with the Audit Committee of the Company's Board of Directors, concluded that the unaudited consolidated financial statements for the three-month period ended March 31, 2024 should be restated to present the identified adjustments discussed below.

Background of Restatement

For the three-month period ended March 31, 2024, the Company did not appropriately (i) estimate variable consideration for customer incentives, (ii) estimate variable consideration for sales returns, (iii) estimate the allowance for credit losses, (iv) estimate excess and obsolete inventory, (v) timely recognize a valuation allowance on deferred tax assets and (vi) reclassify certain prepayments made to suppliers and loss on supplier commitments liability as current or non-current.

Additionally, as part of the restatement, for the three-month period ended March 31, 2024, the Company corrected for (b) previously identified uncorrected misstatements related to out-of-period adjustments, (c) previously recorded amounts reclassifying accounts receivable credit balances and (d) classification of property and equipment transactions on the statement of cash flows.

Effect of Restatement

The following table sets forth the effects of the restatement adjustments on revenue, loss before income taxes and net loss in the consolidated statements of operations and comprehensive loss for the three-month period ended March 31, 2024.

The amounts are presented herein as originally reported in the previously issued financial statements for transparency and consistency. The restatement corrects these errors and reflects the appropriate adjustments.

The financial statement line items impacted by the respective adjustments are labeled in the tables below based on the identifiers from the paragraph above. Below are the Company's restated consolidated statement of operations and comprehensive loss and statement of cash flows with the adjustments for the three-month period ended March 31, 2024. The consolidated statement of shareholders' equity (deficit) has been excluded from the financial statement presentation below as it was only impacted by adjustments to net loss, which is presented below in the consolidated statement of operations and comprehensive loss.

Note 3. Balance sheet components

Inventories, net

Inventories, net consisted of the following (in thousands):

Inventory reserves are established for estimated excess and obsolete inventory equal to the difference between the cost of the inventory and the estimated net realizable value of the inventory based on historical usage, known trends, and market conditions and judgment about the anticipated future consumption and our ability to sell the inventory. At December 31, 2024 and March 31, 2025, excess and obsolescence reserves were $29.4 million and $27.4 million, respectively.

Note 4. Property and equipment

Property and equipment, net consisted of the following (in thousands):

Total depreciation expense was $1.1 million and $0.1 million for the three-month periods ended March 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 of the Company's long-lived assets for recoverability. Based on the quantitative assessment performed, management concluded that the assets were not recoverable. The Company completed a full review of its assets using the cost approach, considering economic obsolescence, and recorded an impairment charge 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. As of March 31, 2025, the asset costs reflect the impact of the impairment recorded in 2024.

Note 5. Software

Software consisted of the following (in thousands):

Amortization of acquired software and software for internal use is computed using the straight-line method over an estimated useful life of generally three toseven years. Amortization expense recognized on acquired software and software for internal use is reflected in Depreciation and amortization expense in the consolidated statements of operations and comprehensive loss. Amortization expense was $0.1 million and $20 thousand for the three-month periods ended March 31, 2024 and 2025, respectively.

Amortization expense recognized on software to be sold or marketed externally was $0.9 million for the three-month periods ended March 31, 2024 and 2025, and is included in cost of revenues in the consolidated statements of operations and comprehensive loss.

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 quantitative assessment performed, management concluded that certain assets were not recoverable and recorded an impairment charge of $0.5 million against its software for internal use. As of March 31, 2025, the gross carrying amount of acquired software and software for internal use reflects the impact of the impairment.

At December 31, 2024, the Company completed the net realizable value test on its software marketed for external sale and identified one product where the net realizable value was below the unamortized capitalized costs of that product and recognized a $0.6 million impairment. As of March 31, 2025, the gross carrying amount of the software marketed for external sale reflects the impact of the impairment recognized.

Based on capitalized software assets at March 31, 2025, estimated amortization expense in future fiscal years is as follows (unaudited and in thousands):

Note 6. Goodwill and intangible assets

There wasno change in the carrying amount of goodwill or intangible assets during the three-month period ended March 31, 2025 (unaudited).

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 or asset group below its carrying amount and tests intangible assets if an indicator suggests that the carrying amount may not be recoverable.

Accordingly, the Company completes a quarterly qualitative triggering events assessment which considers significant events and circumstances such as a reporting unit’s historical and current results, assumptions regarding future performance, operating income or cash flows, strategic initiatives and overall economic factors, including significant negative industry or economic trends and macro-economic developments, and sustained declines in the Company's share price or market capitalization, considered in both absolute terms and relative to peers, to determine whether any of these may indicate that it is more likely than not that the fair value of the reporting unit is less than its carrying value.

As of December 31, 2024 and March 31, 2025, the Company'ssingle reporting unit had a negative carrying value andno further impairment of goodwill was recorded.

For the year ended December 31, 2024, the Company completed an assessment of the customer relationship intangible and determined that the fair value of its customer relationship intangible was negative and the entire value was impaired, resulting in an full impairment loss of $6.6 million.

Intangible assets amortization expense was $0.4 million for the three-month period ended March 31, 2024. As the customer relationship intangible asset was fully impaired as of December 31, 2024, there wasno amortization expense for the three-month period ended March 31, 2025 (unaudited).

Note 7. Debt

At March 31, 2025, the Company had$22.1 million outstanding under its term loan facility and$45.0 million outstanding under its revolving credit facility. As of March 31, 2025, the Company hadno availability left under its revolving credit facility (unaudited).

The following table reflects breakdown of the term loan and revolving credit facilities at December 31, 2024 and March 31, 2025 (in thousands):

As of December 31, 2024, the effective interest rate on the term loan facility was 10.24%. As of March 31, 2025, the effective interest rate on the term loan facility was 10.24% (unaudited).

As of December 31, 2024, the weighted-average interest rate for borrowings outstanding under the revolving credit facility was 8.73%. As of March 31, 2025, the weighted-average interest rate for borrowings outstanding under the revolving credit facility was 8.98% (unaudited).

In addition to the interest charged on the term loan facility and the revolving credit facility, as a result of the covenant violation, 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.

As of March 31, 2025, the Company has made all required quarterly principal and interest payments.

The maturity date of the Term Facility and the Revolving Facility, with all amounts outstanding, becoming due and payable in full, is November 17, 2026 (the “Maturity Date”).

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. As of March 31, 2025, the Company was not in compliance with its quarterly consolidated fixed charge coverage ratio and consolidated leverage ratio covenants. These events of default afford Bank of America the right to declare the amounts immediately due and payable on the outstanding term loan principal amount of$22.1 million and the outstanding revolving credit facility amount of$45.0 million. Although the Company continues regular discussions with the lender to address its noncompliance of the covenants, it has been unable to obtain a waiver of the defaults from the lender, 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.

The term loan facility and revolving credit facility mature on November 17, 2026, however, the covenant violation gives the bank the right to require immediate payment of the outstanding amounts. Accordingly, the entire$22.1 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 sheet as of March 31, 2025. Further, the $0.2 million of unamortized debt issuance costs associated with the term loan facility are classified as current and included in Current portion of long-term debt, net and $0.3 million of unamortized debt issuance costs associated with the revolving credit facility are classified as current and included in Other current assets on the consolidated balance sheet as of March 31, 2025. If the bank requires immediate repayment of the outstanding term loan facility and revolving credit facility, the Company would be required to write-off these unamortized debt issuance costs upon extinguishment of the debt (unaudited).

Interest expense

Net interest expense, including bank charges and amortization of debt issuance costs on the debt, was $0.9 million and$2.0 million for the three-month periods ended March 31, 2024 and 2025, respectively (unaudited). The increase in interest expense is mostly due to the increase in the interest rate and applicable margin on the term loan facility, the addition of interest expense on the revolving credit facility and the additional 2% penalty being assessed by the lender while the Company is in default.

Note 8. 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.

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 $0.1 million and $0.1 million for the three-month periods ended March 31, 2024 and 2025, respectively (unaudited).

Note 9. Shareholders' equity

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 is 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 is 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. 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 the Company's employees.

Share-based compensation

The following table shows total share-based compensation expense for the three-month periods ended March 31, 2024 and 2025 (unaudited and in thousands):

Share options

The Company's time-based share options typically have a contractual term often years from grant date and typically vest over afour-year period. The Company recognizes compensation expense associated with its time-based share options on a straight-line basis over the requisite service period.

The following is a summary of option activity for the Company’s share incentive plans for the three-month period ended March 31, 2025 (unaudited):

The Company uses the Black-Scholes option pricing model to estimate the fair value of share options. There wereno share options granted during the three-month period ended March 31, 2025.

The fair value of share options is estimated using the following weighted-average assumptions (unaudited):

At March 31, 2025, there was $8.0 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 through the second quarter of 2028 (unaudited).

Restricted shares

The Company's time-based RSUs typically vest over afour-year period. The Company recognizes compensation expense associated with its time-based RSUs on a straight-line basis over thefour-year requisite service period.

The following is a summary of restricted shares activity for the Company’s share incentive plan for the three-month period ended March 31, 2025 (unaudited):

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

Of the 106,141 RSUs vested, the Company withheld 28,568 of those shares to pay the employees’ portion of the minimum payroll withholding taxes due at vesting.

The fair value of the RSUs is based on the fair value of the Company's ordinary shares on the grant date. There wereno RSUs granted during the three-month period ended March 31, 2025.

As of March 31, 2025, there was$3.7 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to unvested time-based restricted share units. The unrecognized compensation expense is expected to be recognized through the fourth quarter of 2028 (unaudited).

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 on 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 used to measure the fair value of time-based share options and RSUs, as described above.

On January 29, 2024, the Compensation Committee determined the performance goals for the First Performance Period were not achieved and the total potential shares of 62,500 RSUs were forfeited (unaudited).

On February 4, 2025, the Compensation Committee determined the performance goals for the Second Performance Period were not achieved and the total potential shares of 37,500 RSUs were forfeited (unaudited).

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 initial offering period of six months commenced on January 1, 2021. The current offering period of six months commenced on July 1, 2024 and runs through December 31, 2024. The purchase price of the shares is 85% of the lower of the fair market value of the Company’s ordinary shares on the first trading day of the offering period and the purchase date. The ESPP includes an annual increase to the shares available for sale on the first day of each fiscal year beginning in 2020, equal to the lesser 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 Company added 275,000 shares to the ESPP as of January 1, 2025, under this provision. Due to the Company's noncompliance with the Filing Rule, the Company did not register any additional shares in 2025 for the ESPP. In addition, effective January 1, 2025, management temporarily suspended the ESPP program.

For the three-month period ended March 31, 2024, the Company recognized $0.2 millionof share-based compensation expense related to the ESPP. The Company didnot recognize share-based compensation expense related to the ESPP for the three-month period ended March 31, 2025 (unaudited).

Note 10. Loss per share

Basic net loss per share is computed by dividing net loss by the weighted-average number of shares outstanding during the period. Diluted net earnings per share is computed using the treasury method 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 loss per share when including them would have an anti-dilutive effect. Performance-based share awards are only included in the calculation of diluted loss per share if the performance metric would have been achieved as of March 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 (unaudited and in thousands, except for share and per share data):

In the computation of diluted loss per share for the three-month periods ended March 31, 2024 and 2025, the Company didnot include any share equivalents because their inclusion would have been anti-dilutive(unaudited).

Note 11. Income taxes

Due to forecasting uncertainty for 2024 and 2025, the Company's provision for income taxes at March 31, 2024 and March 31, 2025 is based on the 3-month year-to-date actual results. The Company recorded a provision for income taxes of $1.9 million for the three-month period ended March 31, 2024 and a provision for income taxes of $0.4 million for the three-month period ended March 31, 2025, with an effective tax rate of (11.7)% and (3.2)%, respectively. For the three-month period ended March 31, 2024, the Company's effective tax rate of (11.7)% was different from the statutory rate of 21.0%, primarily due to establishment of a deferred tax liability on hypothetical withholding tax on non-permanent investment in subsidiaries. For the three-month period ended March 31, 2025, the Company’s effective tax rate of (3.2)% was different from the statutory rate of 21.0%, primarily due to an increase in the valuation allowance on the net deferred tax assets of the UK company, maintaining a full valuation allowance on the net deferred tax assets.

In applying the statutory tax rate in the effective income tax rate reconciliation, the Company used the statutory U.S. federal income tax rate of 21% rather than the Cayman Islands zero percent rate.

Note 12. Commitments and contingencies

In accordance with ASC 460, Guarantees, 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 comprehensive loss 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 purchases 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. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, the Company enters into agreements with contract manufacturers and suppliers that allow them to procure inventory and components based upon criteria as defined by us, such as forecasted demand. The Company may be liable to purchase excess product or aged material from its suppliers following reasonable mitigation efforts. The Company establishes a loss on supplier commitments 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.

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 Services cost of revenues on the consolidated statements of operations and comprehensive loss.

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 for the three-months periods ended March 31, 2024 or 2025 (unaudited).

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, that in the Company’s opinion, is likely to have a material adverse effect on its financial condition or results of operations.

Note 17. Subsequent events

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 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.
