Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

Note 5. Goodwill and Intangible Assets

There was no change in the carrying amount of goodwill or intangible assets during the three-month period ended March 31, 2024 (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. If an impairment trigger is identified, a quantitative impairment test is performed.

The qualitative assessment performed for the three-month period ended March 31, 2024 included an assessment of excess inventories, supply chain constraints, and macroeconomic conditions and did not indicate the existence of an impairment trigger that would more likely than not reduce the fair value of our reporting unit below its carrying amount nor indicators suggesting that the carrying amount of intangible assets may not be recoverable. As of December 31, 2023 and March 31, 2024, the Company's market capitalization exceeded its net assets by 106% and 112%, respectively.

Current portion of debt issuance costs		95			111
Total long-term debt, net	$	21,926		$	61,315

As of December 31, 2023, the effective interest rate on the term loan facility was 7.69%. As of March 31, 2024, the effective interest rate on the term loan facility was 9.15% (unaudited). The increase in the interest rate is being driven by the higher applicable margin as a result of the amendment completed on December 29, 2023.

The Company borrowed $40.0 million against its revolving credit facility during the first quarter of 2024. The funds will be used for working capital and normal operations. As of March 31, 2024, the weighted-average interest rate for borrowings outstanding under the revolving credit facility was 8.67% (unaudited).

The increase in interest expense is mostly due to the increase in interest rate on the term loan facility and the addition of interest expense on the revolving credit facility.

Accounting Policies [Abstract]

Business and significant accounting policies

Note 1. Business and 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.

Cambium Networks Corporation and its wholly owned subsidiaries design, develop, and manufacture fixed wireless and fiber broadband and enterprise networking infrastructure solutions that are used by businesses, governments, and service providers in urban, suburban and rural environments. Cambium's products simplify and automate the design, deployment, optimization, and management of broadband and Wi-Fi access networks through intelligent automation.

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of Cambium Networks Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of March 31, 2024, and for the three-month periods ended March 31, 2023 and 2024, and the related notes are unaudited. The unaudited condensed 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, 2024 and results of operations for the three-month periods ended March 31, 2023 and 2024 and cash flows for the three-month periods ended March 31, 2023 and 2024. The condensed consolidated balance sheet as of December 31, 2023 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 condensed 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, 2023 included in the Company’s annual report on Form 10-K and filed with the SEC on March 15, 2024. The results of operations for the three-month period ended March 31, 2024 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, 2024 and through the date of filing this Quarterly Report, the Company was in compliance with all of its payment obligations and the financial covenants under its Amended Credit Agreement. The Company’s obligations under the Amended Credit Agreement do not mature and become due and payable until November 17, 2026. Please refer to Note 6. Debt, regarding the Company’s debt outstanding under its credit facilities with Bank of America.

The Company is actively taking actions to improve its profitability and ensure future compliance with applicable financial covenants, including acceleration of collection of receivables, deferral of expenditures, cost reductions to align the Company’s cost structure with current revenue levels and sales of excess inventory. In addition, the Company continues to focus on operating efficiency and reducing discretionary spending. The Company believes these actions, together with its existing cash balances, provide it with the financial flexibility needed to meet its obligations as they come due over the next twelve months. However, this conclusion depends in part on the Company’s expectations regarding macro-conditions in the markets in which it competes, customer acceptance and purchases of the Company’s products, buying decisions by the Company’s distributors and other factors that are not within the Company’s control. Based on the Company’s current forecasts, the Company is projecting future noncompliance with its financial covenants within the next twelve months, which would result in a non-payment event of default under the Amended Credit Agreement. Such a default would afford the lenders thereunder the right to declare the amounts outstanding thereunder immediately due and payable, and the Company may not be able to obtain a waiver of such a default or otherwise refinance such indebtedness. Due to these uncertainties, 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 condensed consolidated financial statements are issued.

The accompanying condensed 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 condensed 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 2023 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") No. 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands the disclosures required in an entity's income tax rate reconciliation table and requires disclosure of income taxes paid in both U.S. and foreign jurisdictions. The amendments are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, to be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendment requires disclosures of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit of loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The new guidance also requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this update and all existing segment disclosures. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Upon adoption, this guidance should be applied retrospectively to all prior periods presented. The Company is currently evaluating this ASU to determine its impact on the Company's 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 ASC 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.

Commitments and Contingencies

3 Months Ended

Mar. 31, 2024

Commitments and Contingencies Disclosure [Abstract]

Commitments and contingencies

Note 11. 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 the interpretation. 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 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 condensed consolidated statements of operations and corresponding condensed consolidated balance sheets during that period.

Indemnification

The Company generally indemnifies its customers 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. The maximum potential amount of future payments the Company may be required to make under these indemnification agreements is not estimable.

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.

Purchase commitments with contract manufacturers and suppliers

We purchase components from a variety of suppliers and use contract manufacturers to provide manufacturing services for our products. 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 and components based upon criteria as defined by us, such as forecasted demand. Certain of our inventory purchase commitments with contract manufacturers and suppliers relate to arrangements to secure supply and pricing for certain components for multiple periods. We record a liability for firm, noncancelable, and unconditional purchase commitments for quantities in excess of our future demand forecasts consistent with the valuation of our excess and obsolete inventory. The Company may be liable to purchase excess product or aged material or components from our suppliers following reasonable mitigation efforts.

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 its condensed 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 condensed 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 condensed consolidated statements of operations within cost of revenues.

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.

Inventories, net	$	66,878		$	55,593

The decrease in gross inventory was primarily in our PMP and Enterprise products. 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 consumption and our ability to sell the inventory. At December 31, 2023 and March 31, 2024, excess and obsolescence reserves were $23.8 million and $29.9 million, respectively. The increase in the reserve in the first quarter of 2024 was mostly driven by lower demand, mostly for PMP products.

Earnings Per Share [Abstract]

Earnings (Loss) Per Share

Note 9. Earnings (loss) per share

Basic net earnings (loss) per share is computed by dividing net income 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 earnings per share when including them would have an anti-dilutive effect. Performance-based share awards are only included in the calculation of diluted earnings per share if the performance metric would have been achieved as of March 31, 2024 if that had been the end of the contingency period. The following table sets forth the computation of basic and diluted net earnings per share (unaudited and in thousands, except for share and per share data):

Income Tax Disclosure [Abstract]

Income taxes

Note 10. Income taxes

The Company’s provision for income taxes at March 31, 2023 is based upon the estimated annual tax rate for the year applied to federal, state and foreign income. Due to forecasting uncertainty for 2024, the Company's provision for income taxes at March 31, 2024 is based on the 3-month year-to-date actual results. The Company recorded a provision for income taxes of $0.5 million for the three-month period ended March 31, 2023 and a provision for income taxes of $4.5 million for the three-month period ended March 31, 2024, with an effective tax rate of 11.2% and (20.7)%, respectively. In the three-month period ended March 31, 2023, the effective tax rate of 11.2% was different from the statutory rate of 21.0%, primarily due to Foreign Derived Intangible Income and tax benefits arising on Research and Development tax credits. For the three-month period ended March 31, 2024, the Company’s effective tax rate of (20.7%) 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 and US companies, the tax benefit on Foreign Derived Intangible Income and tax benefits arising on U.S. Research and Development tax credits. The Company increased the valuation allowance based on the analysis of cumulative income and loss positions, future income projections, and operating plans. The UK net deferred tax assets at December 31, 2023 were comprised primarily of NOL carryforwards, corporate interest restriction carryforwards and acquired intangibles, amounting to $23.6 million. The movement in the UK valuation allowance during the three-month period ended March 31, 2024 amounted to $5.9 million, for a total valuation allowance at March 31, 2024 of $29.5 million. The U.S. net deferred tax assets at December 31, 2023 were comprised primarily of capitalized research costs and share-based compensation, amounting to $15.8 million. The U.S. net deferred tax assets increased by $1.2 million during the three-month period ended March 31, 2024, for total U.S. net deferred tax assets at March 31, 2024 of $17.0 million. The U.S. valuation allowance at December 31, 2023 was $12.1 million. The increase in the U.S. valuation allowance during the three-month period ended March 31, 2024 amounted to $4.9 million, for a total valuation allowance at March 31, 2024 of $17.0 million.

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. A significant piece of objective evidence evaluated is the cumulative income or loss incurred over the three-year period ended March 31, 2024 and whether the Company projects a loss for the current year ending December 31, 2024. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize the existing deferred tax assets before they otherwise expire. The Company considers projected future taxable income, reversing taxable temporary differences, carryback opportunities, and prudent tax-planning strategies in making this assessment. However, cumulative losses in recent periods are a significant piece of objective negative evidence that limits the Company's ability to consider certain criteria of subjective positive evidence such as projections for future growth. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period in which those temporary differences are deductible. The amount of the deferred tax asset considered realizable will be adjusted in future periods as

necessary based on the reversal pattern of deferred balances and the actual taxable income during the carryforward period, as well as any relevant new facts to be considered.

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 8. 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 continuing 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. On March 18, 2024, the Company registered 1,320,000 additional shares that may 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.

For the three-month periods ended March 31, 2023 and 2024, the Company recorded corresponding income tax benefits of $0.1 million and $0.0 million, respectively.

Share-based compensation

The following table shows total share-based compensation expense for the three-month periods ended March 31, 2023 and 2024 (unaudited and in thousands):


	Three Months Ended March 31,
	2023		2024
Cost of revenues	$	56	$	33
Research and development		1,269		945
Sales and marketing		700		508
General and administrative		850		1,100
Total share-based compensation expense	$	2,875	$	2,586

Share options

The Company's time-based share options typically have a contractual term of ten years from grant date and typically vest over a four-year period. The Company recognized 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, 2024 (unaudited):


	Options			Weighted average exercise price		Weighted Average remaining contractual term (years)		Aggregate intrinsic value
Outstanding at December 31, 2023		4,689,916		$	11.98		7.5	$	617,623

Options exercisable at March 31, 2024		2,639,430		$	13.24		5.7	$	—
Options vested and expected to vest at March 31, 2024		5,171,987		$	10.92		7.5	$	33,841

The Company uses the Black-Scholes option pricing model to estimate the fair value of share options. The Company utilized a forfeiture rate of 8.2% during the three-month period ended March 31, 2024 for estimating the forfeitures of share options granted.

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


	Three Months Ended March 31,
		2023	2024
Expected dividend yield		N/A		—
Risk-free interest rate		N/A		4.36	%
Weighted-average expected volatility		N/A		71.9	%
Expected term (in years)		N/A		5.8
Weighted average grant-date fair value per share of options granted		N/A	$	2.82

There were no share options granted in the three-month period ended March 31, 2023.

At March 31, 2024, there was $12.4 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 first quarter of 2028 (unaudited).

Restricted shares

The Company's time-based RSUs typically vest over a four-year period. The Company recognizes compensation expense associated with its time-based RSUs on a straight-line basis over the four-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, 2024 (unaudited):


	Units			Weighted average grant date fair value
RSU balance at December 31, 2023 1		556,340		$	16.92
RSUs granted		349,920		$	4.28
RSUs vested		(62,913	)	$	17.02
RSUs forfeited 1		(59,337	)	$	15.55
RSU balance at March 31, 2024 1		784,010		$	11.37

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

Of the 62,913 RSUs vested, the Company withheld 4,917 of those shares to pay the employees’ portion of the minimum payroll withholding taxes.

The fair value of the RSUs is based on the fair value of the Company's ordinary shares on the grant date. The Company utilized a forfeiture rate of 8.2% during the three-month period ended March 31, 2024 for estimating the forfeitures of RSUs granted.

As of March 31, 2024, there was $7.1 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 first 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 contain a performance-based vesting criteria and included 60,000 share options and 135,000 restricted share units. The performance-based awards have two separate annual performance periods, with 50% of the performance-based awards vesting over each of the annual performance periods ending on December 31, 2023 ("First Performance Period") and December 31, 2024 ("Second Performance Period") if the performance goal is met. If the performance goal for that performance period is not met, the performance-based awards do not vest and are forfeited. The performance goal is 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.

For performance-based awards that vest during the First Performance Period, the Company's Compensation Committee retains 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. 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).

Unlike the performance-based awards in the First Performance Period, the Compensation Committee does 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, exists on the date that the performance-based awards are issued by the Company. As of March 31, 2024, based on the total potential shares that could be earned, there were 50,000 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 RSUs. The Company has not recognized any compensation expense on these performance-based awards since the achievement of the performance goal is not probable. As of March 31, 2024, there was $0.7 million in unrecognized pre-tax compensation expense, net of estimated forfeitures, related to these unvested performance-based share awards for the Second Performance Period, which will be recognized over the requisite service period from January 1, 2024 through the first quarter of 2025 if it is probable that the adjusted earnings per share metric will be achieved (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 January 1, 2024 and runs through June 30, 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 registered 275,000 additional shares on March 18, 2024.

For the three-month periods ended March 31, 2023 and 2024, the Company recognized $0.3 million and $0.2 million, respectively, of share-based compensation expense related to the ESPP (unaudited).

Revenues from contracts with customers

Revenue from Contract with Customer [Abstract]

Revenues from contracts with customers

Note 13. Revenues from contracts with customers

Revenues consist primarily of revenues from the sale of hardware products with essential embedded software. Revenues also include amounts for software products, extended warranty on hardware products and subscription services. Substantially all products are sold through distributors and other channel partners, such as resellers, managed service providers 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 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, and purchased extended warranty on hardware products have been identified as separate and distinct performance obligations.

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. An adjustment to revenue is made to adjust the transaction price to exclude the consideration related to products expected to be returned. The Company records an asset at the carrying amount of the estimated stock returns and a liability for the estimated amount expected to be refunded to the customer. The transaction price also excludes other forms of consideration provided to the customer, such as volume-based rebates and co-operative marketing allowances.

The Company recognizes revenue when, or as, it satisfies a performance obligation by transferring control of a promised product or service to a customer. Revenue from hardware products with essential embedded software is recognized when control of the asset is transferred, which is typically at the time of shipment. Revenue from perpetual license software is recognized at the point in time that the customer is able to use or benefit from the software. Extended warranty on hardware products is a performance obligation that is satisfied over time, beginning on the effective date of the warranty period and ending on the expiration of the warranty period. The Company recognizes revenue on extended warranties on a straight-line basis over the warranty period. Revenue from software subscriptions is recognized ratably over the term in which the services are provided and the performance obligation is satisfied.

The Company enters into revenue arrangements that may consist of multiple performance obligations, such as hardware products and extended warranty. 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.

The following table summarizes contract balances as of December 31, 2023 and March 31, 2024 (in thousands):


	December 31, 2023		March 31, 2024

Trade accounts receivable, net of allowance for credit losses	$	63,656	$	58,146
Deferred revenue - current		8,765		8,510
Deferred revenue - noncurrent		10,473		10,074
Refund liability		8,723		8,826

Deferred revenue consists of amounts due or received from customers in advance of the Company satisfying performance obligations under contractual arrangements. Deferred revenue is classified as current or noncurrent based on the timing of when revenue will be recognized. The changes in deferred revenue were due to normal timing differences between the Company’s performance and the customers’ payment.

The refund liability is the estimated amount expected to be refunded to customers in relation to product exchanges made as part of the Company’s stock rotation program and returns that have been authorized, but not yet received by the Company. It is included within Other current liabilities in the condensed consolidated balance sheets.

Receivables and concentration of credit risk

Trade accounts receivable represent amounts for which the Company has an unconditional right to payment. Amounts are in accordance with contractual terms and are recorded at face amount less an allowance for credit losses. 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 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.

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 its customers are generally net 30 to 60 days. The Company had one customer representing more than 10% of trade receivables at December 31, 2023 and two customers representing more than 10% of trade receivables at March 31, 2024.

Remaining performance obligations

Remaining performance obligations represent the revenue that is expected to be recognized in future periods related to performance obligations included in a contract that are unsatisfied, or partially satisfied, as of the end of a period. As of December 31, 2023, deferred revenue (current and noncurrent) of $19.2 million represents the Company’s remaining performance obligations, of which $8.8 million is expected to be recognized within one year, with the remainder to be recognized thereafter. As of March 31, 2024, deferred revenue (current and noncurrent) of $18.6 million represents the Company’s remaining performance obligations, of which $8.5 million is expected to be recognized within one year, with the remainder to be recognized thereafter (unaudited).

Revenue recognized during the three-month period ended March 31, 2024 which was previously included in deferred revenues as of December 31, 2023 was $2.7 million, compared to $3.4 million of revenue recognized during the three-month period ended March 31, 2023, which was previously included in deferred revenues as of December 31, 2022 (unaudited).

Cost to obtain a contract

Sales commissions are incremental costs of obtaining a contract. The Company has elected to recognize these expenses as incurred, as the amortization period of these costs is one year or less.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Business and Significant Accounting Policies (Policies)	3 Months Ended
Business and Significant Accounting Policies (Policies)	Mar. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of Cambium Networks Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements as of March 31, 2024, and for the three-month periods ended March 31, 2023 and 2024, and the related notes are unaudited. The unaudited condensed 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, 2024 and results of operations for the three-month periods ended March 31, 2023 and 2024 and cash flows for the three-month periods ended March 31, 2023 and 2024. The condensed consolidated balance sheet as of December 31, 2023 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 condensed 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, 2023 included in the Company’s annual report on Form 10-K and filed with the SEC on March 15, 2024. The results of operations for the three-month period ended March 31, 2024 are not necessarily indicative of the operating results to be expected for the full year.
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 March 31, 2024 and through the date of filing this Quarterly Report, the Company was in compliance with all of its payment obligations and the financial covenants under its Amended Credit Agreement. The Company’s obligations under the Amended Credit Agreement do not mature and become due and payable until November 17, 2026. Please refer to Note 6. Debt, regarding the Company’s debt outstanding under its credit facilities with Bank of America. The Company is actively taking actions to improve its profitability and ensure future compliance with applicable financial covenants, including acceleration of collection of receivables, deferral of expenditures, cost reductions to align the Company’s cost structure with current revenue levels and sales of excess inventory. In addition, the Company continues to focus on operating efficiency and reducing discretionary spending. The Company believes these actions, together with its existing cash balances, provide it with the financial flexibility needed to meet its obligations as they come due over the next twelve months. However, this conclusion depends in part on the Company’s expectations regarding macro-conditions in the markets in which it competes, customer acceptance and purchases of the Company’s products, buying decisions by the Company’s distributors and other factors that are not within the Company’s control. Based on the Company’s current forecasts, the Company is projecting future noncompliance with its financial covenants within the next twelve months, which would result in a non-payment event of default under the Amended Credit Agreement. Such a default would afford the lenders thereunder the right to declare the amounts outstanding thereunder immediately due and payable, and the Company may not be able to obtain a waiver of such a default or otherwise refinance such indebtedness. Due to these uncertainties, 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 condensed consolidated financial statements are issued. The accompanying condensed 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 condensed 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	Update to Significant Accounting Policies There have been no material changes to the Company’s significant accounting policies disclosed in the 2023 Form 10-K, Part II, Item 8.
Recently issued accounting standards not yet adopted	Recently issued accounting standards not yet adopted In December 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands the disclosures required in an entity's income tax rate reconciliation table and requires disclosure of income taxes paid in both U.S. and foreign jurisdictions. The amendments are effective for fiscal years beginning after December 15, 2024, with early adoption permitted, to be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating this ASU to determine its impact on the Company's disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendment requires disclosures of significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit of loss, an amount and description of its composition for other segment items, and interim disclosures of a reportable segment's profit or loss and assets. The new guidance also requires that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this update and all existing segment disclosures. The amendments are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Upon adoption, this guidance should be applied retrospectively to all prior periods presented. The Company is currently evaluating this ASU to determine its impact on the Company's 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 ASC 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.

Employee Benefit Plans

Retirement Benefits [Abstract]

Employee benefit plans

Note 7. Employee benefit plans

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

U.S. plan

U.S. employees that satisfy certain eligibility requirements, including requirements related to age and length of service, are eligible to participate in the Cambium Networks, Inc. 401(k) Plan. The plan is intended to qualify as a tax-qualified 401(k) plan so that contributions to the 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) plan. Under the 401(k) plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee as directed by participants. Under the Cambium Networks, Inc. 401(k) Plan, the Company matches 100% of employee contributions to the 401(k) plan up to a maximum amount of 4% of eligible wages, which matching contributions are subject to vesting in equal annual increments over two years of service. All contributions, including the Company match, are made in cash. Contributions made by the Company under the Cambium Networks, Inc. 401(k) Plan were $0.4 million and $0.2 million for the three-month periods ended March 31, 2023 and 2024, respectively.

UK plan

UK employees who satisfy certain eligibility requirements 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% of eligible compensation 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 $0.1 million and $0.1 million for the three-month periods ended March 31, 2023 and 2024, respectively.
