RF Materials' growth story is built on two powerful engines: one that's firing up right now, and another set to ignite next. This dual-engine thesis suggests growth from both optical components for the AI boom and Radio Frequency (RF) components for the next wave of 5G expansion.
The first engine is optical communications. The rapid expansion of AI data centers has created huge demand for high-speed components. A key customer, Lumentum, is expanding its U.S. manufacturing for advanced CPO (Co-Packaged Optics) lasers, with a major production ramp-up expected in late 2026. This directly benefits RF Materials, which supplies essential packages for these lasers. This is the 'optical now' part of the story, driven by the immediate needs of the AI industry.
Then there's the second engine: the RF upcycle. This is the 'RF next' part, and its foundation is being laid by U.S. government policy. First, in July 2025, a law was passed mandating a new pipeline of wireless spectrum for auction, providing a clear roadmap for the future. Second, this policy clarity gave major carriers like AT&T the confidence to announce a massive, multi-year $250 billion investment plan in March 2026 to build out their 5G and fiber networks. This sequence—policy first, then investment—creates a predictable, long-term demand cycle for RF Materials' 5G components.
This outlook is further strengthened by global trends. The U.S. and E.U. continue to restrict the use of Chinese telecom equipment from companies like Huawei, opening the door for non-Chinese suppliers. At the same time, a key competitor, NXP, has exited the 5G RF power market, reducing supply and potentially increasing market share for RF Materials and its parent company, RFHIC. These factors create a more favorable competitive landscape.
However, it's important to consider the company's valuation. RF Materials' stock is already trading at a historically high price-to-book ratio. While it's much cheaper than U.S. optical giants like Lumentum, it's more expensive than its domestic parent, RFHIC. The justification for its target price hinges on both engines firing successfully. The market has priced in the optical growth; now, it's waiting for the RF cycle to prove itself. Success depends on both the optical ramp and the spectrum auctions proceeding on schedule through 2026.
- Glossary
- CPO (Co-Packaged Optics): A technology that integrates optical components very close to processing chips to increase speed and reduce power consumption in data centers.
- GaN (Gallium Nitride): A semiconductor material ideal for high-power, high-frequency applications, making it essential for modern 5G base station transmitters.
- RF (Radio Frequency): Refers to the technology using electromagnetic waves for wireless communication, such as 5G mobile networks. RF components are the physical parts that send and receive these signals.
