Explanatory Note

Cambium Networks Corporation ("Cambium" or the "Company") is filing this Amendment No. 1 to its Current Report on Form 8-K, filed with the Securities and Exchange Commission (the "SEC") on February 15, 2024 (the "Prior Report"), in order to update the financial information for the three-month period and year ended December 31, 2023 included in Exhibit 99.1 to the Prior Report (the "Original Earnings Release") to reflect an increase to the valuation allowance against its deferred tax assets and an increase to the loss on supplier commitments. Subsequent to issuing the Original Earnings Release, the Company determined it needed to recognize an additional valuation allowance against its deferred tax assets of $11.5 million due to the intercompany relationship between Cambium's entities and a loss at the Company's UK entity and an additional loss on supplier commitments of $2.3 million due to additional components identified which required a reserve.

An updated version of the Original Earnings Release and the included Quarterly and Full Year selected information tables, Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Cash Flows, Supplement Schedule of Non-GAAP Adjusted EBITDA and Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures have been corrected on Exhibit 99.1 to this Amendment No. 1.

Item 2.02 Results of Operations and Financial Condition.

The Exhibit 99.1 attached hereto is a replacement of the Exhibit furnished on the Original Earnings Release.

The foregoing information is furnished pursuant to Item 2.02 and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") or incorporated by reference in any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
