TOMI Environmental Solutions, Inc.: what insiders have been doing
TOMI Environmental Solutions, Inc. belongs to the Energy sector. Filings by its managers are published through SEC (Form 4). Over the twelve months to 21 October 2026, 6 filings were filed, from 3 insiders.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
There has been no open-market purchase by an insider of TOMI Environmental Solutions, Inc. for at least a year. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. Section 16 rules allow two business days to file each Form 4.
For context, the typical company on the same exchange (median of 5,456 companies) published 22 filings over the same period, against 6 filings here. The full history, which starts in 2016, counts 6 purchases against 1 sale. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 5.6 m USD and net income at -3.7 m USD.
Other companies in the same sector with recent insider buying flagged by our signals: AXIA Energia S.A. and RGC Resources Inc. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.

About TOMI Environmental Solutions, Inc.
TOMI Environmental Solutions, Inc. (NASDAQ: TOMZ) is a U.S.-listed company traded on the NASDAQ market in the United States, focused on disinfection, decontamination, and infection-prevention solutions. Headquartered in Frederick, Maryland, the company operates in a specialized niche at the intersection of healthcare, industrial hygiene, and controlled environments. For investors, TOMI is best viewed as a thematic small-cap exposure to structural demand for biosecurity in hospitals, laboratories, cleanrooms, pharmaceutical manufacturing sites, transportation assets, and public facilities. ([investor.tomimist.com](https://investor.tomimist.com/?utm_source=openai))
The company’s core business is built around its proprietary Binary Ionization Technology® (BIT™), marketed under the SteraMist® brand. TOMI describes BIT as a hydrogen-peroxide-based platform designed for indoor surface decontamination and pathogen reduction in sensitive environments. Its commercial model combines manufacturing, direct sales, licensing, and related services.

Historically, TOMI has developed around a proprietary technology platform and a licensing-oriented commercialization strategy. Its competitive position is driven less by scale than by specialization, differentiated technology, and the ability to address use cases where decontamination performance is mission-critical. The company also emphasizes an international footprint and ongoing commercial expansion, with a particular focus on life sciences, healthcare, and pharmaceutical manufacturing. ([investor.tomimist.com](https://investor.tomimist.com/?utm_source=openai))
Recent developments suggest an active transformation phase. In 2025 and 2026, TOMI reported improving quarterly trends, higher revenue, and a larger set of commercial opportunities. In March 2026, the company released full-year 2025 results and highlighted growth initiatives, including continued R&D investment to broaden SteraMist applications across life sciences, food safety, and commercial markets. In April 2026, TOMI announced a transformative letter of intent to merge with Carbonium Core, Inc., while also communicating more aggressive positioning around defense-related and autonomous decontamination applications. Taken together, these updates indicate a company still dependent on a relatively narrow product base, but actively working to expand recurring revenue, deepen customer adoption, and widen its end-market reach.
