About Guerrilla RF, Inc.
Guerrilla RF, Inc. is a United States-based semiconductor company focused on radio-frequency (RF) and microwave devices. It is listed on the U.S. market under the ticker GUER on OTCQX rather than NYSE/NASDAQ at this time. The company is headquartered in Greensboro, North Carolina, United States, and was founded in 2013 with the stated mission of applying RF semiconductor technology to underserved markets. From the outset, Guerrilla RF has positioned itself as a specialist supplier of high-performance RF solutions rather than a broad-line integrated device manufacturer. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1832487/000143774926009848/guer20251231_10k.htm?utm_source=openai))
The business model is that of a fabless semiconductor designer. Guerrilla RF develops products in-house across design, applications engineering, sales, and customer support, while outsourcing wafer fabrication, assembly, and test to subcontractors. This structure gives the company access to multiple process technologies without owning a heavy manufacturing footprint. Its primary external foundries are located in Taiwan and Singapore, with assembly and test mainly in Malaysia, and it also uses foundry capacity in the United States. For investors, this means the company is asset-light relative to integrated chipmakers, but also more exposed to third-party supply chain execution and capacity availability. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1832487/000143774926009848/guer20251231_10k.htm?utm_source=openai))

Guerrilla RF’s product portfolio centers on MMICs and other high-performance RF/microwave semiconductors used by wireless OEMs. According to company disclosures, its devices serve a range of high-growth end markets, including 5G/4G macro and small-cell base stations, SATCOM, cellular repeaters and DAS, automotive telematics, military communications, navigation, and high-fidelity wireless audio. The company says it has a portfolio of more than 100 RF and microwave devices, with additional products in development. That indicates a strategy built on iterative product expansion, technical support, and application-specific performance rather than commodity-scale volume. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1832487/000143774925009474/ex_794733.htm?utm_source=openai))
In competitive terms, Guerrilla RF occupies a niche position in a market dominated by larger, better-capitalized semiconductor vendors. Its competitive edge lies in speed of development, product performance, application support, and the ability to target markets that can be overlooked by larger suppliers. However, that niche focus also implies meaningful competitive pressure, customer concentration risk, and dependence on capital markets and operational execution. The company’s SEC filings also highlight typical small-cap semiconductor risks, including industry volatility, the need for financing, and reliance on key personnel. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1832487/000143774926009848/guer20251231_10k.htm?utm_source=openai))
Recent developments suggest improving momentum. In March 2026, Guerrilla RF reported fourth-quarter and full-year 2025 results showing a record quarterly revenue figure, stronger gross profit, and, importantly, operating profitability and positive operating cash flow in Q4 2025. A separate SEC filing in December 2025 showed an amended loan arrangement extending maturities, which suggests active balance-sheet management alongside improving operating performance. For French-speaking investors, Guerrilla RF is best viewed as a U.S. small-cap RF semiconductor story with a specialized product set, a fabless model, and an execution-sensitive path toward scaling profitability.
