Cambium Networks Corp

In November 2025, the Company engaged BDO USA, P.C. (“BDO”) as its independent registered public accounting firm to audit its annual consolidated financial statements for 2023, 2024 and 2025 and to review interim quarterly consolidated financial statements for all quarterly periods in 2025, and to review restated quarterly financial statements for all quarterly periods in 2023 and 2024. BDO's audit fees totaled $2.0 million for its services to audit the Company's annual consolidated financial statements for 2023 and 2024 and to review interim quarterly consolidated financial statements in 2023 and 2024 and $0.8 million to review the interim quarterly consolidated financial statements for all quarterly periods in 2025 and audit the Company's annual consolidated financial statements for 2025. It is not possible to break out the Audit Fees related to each of 2023 and 2024 and, therefore, the amounts represent fees for auditing both years. The Company did not engage BDO for any other audit-related, tax or other consulting services during these periods.

In March 2026, the Company engaged BDO LLP in the United Kingdom (“BDO UK”) as its independent registered public accounting firm to audit its annual financial statements for 2024 for Cambium Networks, Ltd. The audit is currently ongoing and fees are estimated to be $0.2 million. The Company did not engage BDO UK for any other audit-related, tax or other consulting services during these periods.

In accordance with its charter, the Audit Committee approves in advance all audit and non-audit services to be provided by the Company's independent registered public accounting firm.
