Cambium Networks
Cambium Networks makes fixed wireless and Wi-Fi gear for carriers, enterprises, and rural broadband networks.
Cambium is burning cash faster than it can raise it, trading on the OTC Expert Market with going-concern language attached, while larger rivals hold the enterprise Wi-Fi market it once competed in.
Cambium Networks sells wireless networking equipment to businesses, competing against much larger companies like Cisco and smaller, cheaper makers like Ubiquiti. The company is not hard to replace because bigger competitors like Cisco offer similar products with better support, while cheaper alternatives like Ubiquiti undercut on price, leaving Cambium squeezed in the middle with shrinking sales. What could change everything is whether Cambium can stay on the stock market and avoid a cash crisis in the next 6 to 12 months, because right now the company is burning through money faster than it is making it.
Q2/Q3 2026 earnings show revenue growth or continued year-over-year decline. Growth would signal Wi-Fi 7 pull-through; continued decline would confirm shrinking customer base.
Any capital raise announcement and its dilution terms. Heavily dilutive terms would show going-concern risk is materializing, not just disclosed.

| Rival | Direction | Evidence |
|---|---|---|
| Cisco/Meraki | losing to | Cisco/Meraki held about 40% WLAN market share per a 2022 Network World analysis, dwarfing Cambium's niche position |

| Ubiquiti | gaining on | Ubiquiti led wireless WAN mindshare at 23.3% per PeerSpot data as of July 2026, ahead of Cambium on cost |

- Is Cambium Networks profitable in 2026?
- No. Cambium Networks posted FY2025 revenue of $159.6M, down 10% year over year, with a net loss of $38.5M, narrowed from a $74.5M loss in FY2024. The FY2025 10-K, filed May 1, 2026, also contains explicit going-concern language tied to liquidity and delisting.
- Is Cambium Networks going bankrupt?
- Not confirmed, but risk is real. Its FY2025 10-K (filed 2026-05-01) flags explicit going-concern doubt, cash was just $11.3M against a $38.5M annual loss, and Nasdaq trading was suspended March 27, 2026, moving shares to the OTC Expert Market under CMBMF.
- Is Cambium Networks still listed on Nasdaq?
- No. Nasdaq suspended trading of CMBM on March 27, 2026, after a delisting determination, moving shares to the OTC Expert Market as CMBMF. Cambium filed an appeal and became current with SEC filings by May 4, 2026, but relisting is not guaranteed.
- Who is Cambium Networks' biggest competitor?
- Cambium is squeezed between premium incumbents Cisco/Meraki (about 40% WLAN share per a 2022 Network World analysis) and HPE-Aruba above, and low-cost players like Ubiquiti (23.3% wireless WAN mindshare, PeerSpot, July 2026) below, per company-reported and industry data.
- Could AI replace Cambium Networks' products?
- Not directly, since Cambium sells physical RF hardware, but AI-driven optimization is now table-stakes: Cisco, Aruba, and Cambium itself (its X7-56X AP, launched July 22, 2026) all ship AI RF features, eroding the one differentiator Cambium had left.
- Who owns Cambium Networks?
- Cambium Networks Corporation is publicly traded with no controlling parent, historically a Russell 2000 component on Nasdaq under CMBM. As of March 27, 2026, shares moved to the OTC Expert Market under ticker CMBMF after a Nasdaq delisting determination.
