Given the forecasted negative EPS for Q1-Q4 2026, what are the underlying reasons for this projected decline after positive Q3/Q4 2025?

It's an astute observation regarding Cambium Networks Corporation's (CMBM) forecasted EPS, especially the projected shift from positive in late 2025 to negative throughout 2026. This indeed warrants a deeper look into the underlying factors.

Based on Fintel's analyst estimates, the trajectory for CMBM's quarterly EPS shows a clear decline:

• Q3 2025: Analysts forecast an average EPS of $0.37.1
• Q4 2025: The forecast remains positive at $0.44.1
• Q1 2026: The outlook turns negative, with an estimated -$0.07 EPS.1
• Q2 2026: This trend continues with a -$0.06 EPS forecast.1
• Q3 2026: The forecast is -$0.05 EPS.1
• Q4 2026: The year is expected to close with a -$0.03 EPS.1

It's worth noting a potential discrepancy in the aggregated annual forecast, which shows a positive $2.93 EPS for 2026, despite all individual quarterly forecasts being negative. This suggests that the annual figure might be an outlier or derived from a different set of analysts or methodology than the quarterly estimates.1

A significant factor likely contributing to this cautious, and in some cases, negative, analyst outlook for 2026 stems from the company's recent challenges with financial reporting. Cambium Networks has received multiple delinquency notices from Nasdaq for failing to timely file its Quarterly Reports on Form 10-Q for Q1 2025 and Q2 2025, as well as its Annual Report on Form 10-K for the fiscal year ended December 31, 2024.2 These reporting delays often signal internal control weaknesses, accounting issues, or other operational hurdles that can erode investor confidence and make it difficult for analysts to accurately project future profitability.

While recent company updates from August and November 2025 indicated some positive trends, such as "stable shipping levels," "improved quarterly bookings," and "normalized inventory in the channel," these operational comments may not fully offset the concerns raised by the delayed financial disclosures.3 The absence of comprehensive and timely financial statements makes it challenging to assess the full financial health and future prospects of the company, leading analysts to adopt a more conservative stance on earnings.

Investigate the specific reasons cited by Cambium Networks for the delays in filing their Form 10-K for FY 2024 and Form 10-Q reports for Q1 and Q2 2025.

It's an excellent point to investigate the specific reasons cited by Cambium Networks for their filing delays. Understanding these details is crucial for assessing the company's operational and financial health beyond just the fact of the delays.

Cambium Networks has indeed been transparent about the reasons for its inability to timely file its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and subsequently its Quarterly Reports on Form 10-Q for Q1 and Q2 2025.

Reasons for 2024 10-K Delay

According to an EX-99.1 filing from March 31, 2025, Cambium Networks required additional time to finalize its consolidated financial statements and complete its assessment of internal control over financial reporting and related disclosures. More specifically, the company identified certain material weaknesses in its preliminary assessment of internal control over financial reporting for FY 2024, which include:

• Allowance for Credit Losses: Issues related to the estimation and accounting for uncollectible accounts.1
• Customer Incentives: Challenges in the accounting and reporting of incentives provided to customers.1
• Information Technology General Controls (ITGC): Deficiencies in the general controls surrounding the company's IT systems, which are foundational to financial reporting accuracy.1

These newly identified material weaknesses were in addition to those previously disclosed in the company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2024.1

Impact on 10-Q Filings

The fundamental issues with internal controls and the time needed to finalize the annual financial statements are the primary drivers behind the subsequent delays in the Q1 and Q2 2025 Form 10-Q filings. Robust internal controls are essential for the timely and accurate preparation of both annual and quarterly financial reports. When these controls are deficient, it creates a cascading effect, making it difficult to produce reliable financial statements for any period. Nasdaq has issued multiple delinquency notices to Cambium Networks regarding these ongoing filing failures.2

Such extensive delays and identified material weaknesses typically signal to analysts and investors a higher risk profile, contributing to the cautious or negative EPS forecasts you highlighted. It underscores the importance of strong internal controls for maintaining investor confidence and predictable financial performance.
