Key statistics
from XBRL data in SEC filingsAI briefing
from the latest 10-K, 10-Q and 8-K eventsBirchtech Corp. is a specialty activated carbon technology provider focused on mercury emissions capture for coal-fired power plants and emerging PFAS water treatment solutions.
What they do
Birchtech supplies patented and proprietary two-part Sorbent Enhancement Additive (SEA) systems for mercury removal at coal-fired power plants, tailoring products to each customer's units and claiming lower cost and less operational impact than traditional sorbent injection. The company is also developing next-generation sorbent technologies for water purification, targeting PFAS and PFOS 'forever chemicals' in drinking water.
Revenue drivers
- Mercury emissions capture (SEA) — Core revenue source from sales of sorbent products and services to coal-fired power plants in North America, driven by MATS regulations and patent enforcement converting infringers to customers.
- Patent litigation and licensing — Revenue from converting infringers to supply contracts or non-exclusive licenses for SEA patents; litigation initiated in 2019 across multiple jurisdictions.
- Water treatment (PFAS removal) — Newly introduced business in April 2024, selling next-generation sorbents that use less activated carbon; still developing, with no material revenue disclosed.
Recent performance
Annual revenue was $17.6M in 2025, flat versus 2024, but down from $21.6M in 2022; net loss improved to -$3.0M in 2025 from -$10.8M in 2024. Quarterly revenue fluctuated: $7.4M in Q3 2025, $3.8M in Q4 2025, $4.2M in Q1 2026, and $3.8M in Q2 2026. As of June 30, 2026, cash was $11.8M, total assets $19.4M, and shareholder equity $8.2M. Operating cash flow was negative $700K in 2025, following a positive $19.2M in 2023.
Strategy
Management's stated goal is to enforce patent rights against infringers of the SEA process, converting them to supply contracts or licensing arrangements. The company is expanding into water treatment with next-generation sorbents targeting PFAS regulations, aiming for lower activated carbon usage and improved sustainability. They emphasize a science-based approach—auditing each plant and tailoring formulations—to maintain competitive advantage in mercury removal.
Risks
- Coal decline — Reduced coal-fired generation due to renewables and plant closures has already negatively affected results, and continued declines would shrink demand.
- Regulatory rollback of MATS — The 2025 EPA repeal of 2024 MATS amendments and the presidential proclamation exempting certain plants from 2027-2029 could reduce required mercury controls and lower demand.
- Technological change — Evolving industry standards and alternative mercury capture methods could make current products less competitive or obsolete.
- Litigation uncertainty — Patent enforcement is unpredictable; adverse outcomes or prolonged cases could divert resources and fail to convert infringers to revenue.
Outlook
Management expects the MATS rollback to reduce near-term regulatory pressure for mercury compliance, but the company remains focused on patent enforcement and converting infringers. They are advancing water treatment products, anticipating PFAS monitoring requirements by 2027 and compliance standards as growth catalysts. No specific revenue or profitability guidance was provided.
