Cambium Networks, the unsung hero of fixed wireless broadband, has been battling headwinds in recent quarters. Enterprise revenue took a hit, inventory piled up, and the highly anticipated 6GHz spectrum approval got bogged down in regulatory red tape. Yet, buried within their latest earnings call transcript lies a tantalizing clue that might signal a dramatic turnaround: the stabilization of PMP channel inventories.

While analysts fixated on the woes of the Enterprise segment and the delayed 6GHz rollout, this subtle shift in PMP inventory went largely unnoticed. Could it be the canary in the coal mine, hinting at a surge in demand just waiting to be unleashed?

Here's why this seemingly insignificant detail holds such potential:

The PMP (Point-to-Multipoint) segment caters to Wireless Internet Service Providers (WISPs), a crucial player in bridging the digital divide. Unlike the tumultuous Enterprise market, characterized by overstuffed channels and fierce competition, the WISP ecosystem has quietly absorbed Cambium's PMP inventory. While Q4 2023 saw a slight sequential dip in PMP revenue, attributed to a large 28GHz fixed 5G shipment in the prior quarter, the stabilization of channel inventories suggests a healthy underlying demand picture.

Now, factor in the imminent arrival of 6GHz spectrum, expected in the first half of 2024. Cambium is poised to capitalize on this game-changing development with their ePMP 4600 and PMP 450v product lines, already garnering positive feedback from early adopters like Nextlink. These 6GHz solutions promise to unlock gigabit broadband speeds for WISPs, enabling them to compete head-on with fiber and cable providers.

The pent-up demand for these products, coupled with the clean channel inventory, creates a potent recipe for explosive growth. Imagine a scenario where the FCC finally grants its approval, unleashing a flood of orders from WISPs eager to deploy 6GHz solutions. Cambium, with its lean inventory position, stands ready to fulfill these orders without delay, capturing a significant share of this burgeoning market.

Consider this: Cambium's full year 2024 revenue guidance ranges from $215 million to $245 million, implying a potential 11% growth at the high end. Achieving this requires a significant second-half acceleration, fueled by both Enterprise recovery and PMP expansion. If the 6GHz catalyst ignites as anticipated, Cambium's PMP segment could easily exceed its 'modest growth' projection, propelling the company towards the higher end of its guidance.

But it's not just about the numbers. This inventory detail reveals a deeper narrative: Cambium's quiet resilience in the face of adversity. While grappling with Enterprise challenges, the company has methodically streamlined its operations, trimmed costs, and cultivated a robust, demand-driven PMP business. It's a testament to their adaptable business model and unwavering focus on their core strengths.

It's a detail that discerning investors would be wise to heed. Could this be the turning point for Cambium, marking the beginning of a remarkable growth story? Only time will tell, but the evidence suggests that the company is on the cusp of something truly extraordinary.
