About Omnitek Engineering Corp

Omnitek Engineering Corp. is a U.S. industrial micro-cap that trades on OTCQB under the ticker OMTK. It is not a NYSE/NASDAQ-listed company based on the latest SEC disclosures, so investors should treat it as a small, over-the-counter issuer rather than a mainstream exchange-listed name. The company is headquartered in Vista, California, United States, and began operations on October 10, 2001 as a spin-off from Nology Engineering, Inc. That origin matters: Omnitek was built around engineering know-how and proprietary combustion-related technology rather than around a broad manufacturing footprint.([sec.gov](https://www.sec.gov/Archives/edgar/data/1404804/000109690625000515/omtk-20241231.htm?utm_source=openai)) Omnitek’s core business is the development and sale of proprietary technology to convert diesel engines to alternative fuels, alongside new alternative-fuel engines and complementary products. The company’s solutions are aimed at stationary applications and global transportation markets, including light commercial vehicles, buses, heavy-duty trucks, rail, and marine applications. Management also states that its technology can be applied to compressed natural gas (CNG), liquefied natural gas (LNG), renewable natural gas (RNG/biogas), hydrogen (H2), and propane (LPG). That product breadth gives Omnitek exposure to the decarbonization theme, especially in fleets and industrial uses where retrofit economics can matter, but the business remains niche and highly specialized.([sec.gov](https://www.sec.gov/Archives/edgar/data/1404804/000109690625000515/omtk-20241231.htm?utm_source=openai)) From a competitive standpoint, Omnitek is positioned as a technology-driven small player rather than a scaled platform. Its differentiation comes from proprietary engineering, patents, and trademarks, including two U.S. patents cited in the company’s filing. The business operates from a roughly 11,751-square-foot industrial facility in Vista, which underscores its lightweight operating model and suggests limited production scale versus larger OEMs or Tier-1 suppliers. The company also faces meaningful concentration risk: in 2024, four customers accounted for about 72% of sales, while two suppliers accounted for 83% of product purchases.([sec.gov](https://www.sec.gov/Archives/edgar/data/1404804/000109690625000515/omtk-20241231.htm?utm_source=openai)) Recent filing activity shows a company still in execution mode. In its Form 10-Q for the nine months ended September 30, 2025, Omnitek reported that revenue growth was primarily driven by product mix, with gross margin of 42% versus 40% a year earlier. Operating expenses were slightly lower year over year, and research and development spending remained modest. The company also disclosed an equity incentive award in April 2025, granting President and CEO Werner Funk a non-qualified stock option for 50,000 shares. For investors, Omnitek is best understood as a U.S.-based alternative-fuels engineering micro-cap with thematic upside tied to fleet decarbonization, but with the usual small-company constraints: customer concentration, supplier dependence, and ongoing financing sensitivity.([sec.gov](https://www.sec.gov/Archives/edgar/data/1404804/000109690625001885/omtk-20250930_10q.htm?utm_source=openai))
