Business Overview
Birch Tech specializes in environmental technologies focused on emissions control and water treatment. The company generates revenue primarily through its air division, which supplies activated carbon sorbents to coal-fired utilities under patented SEA (Sorbent Enhancement Additives) technology, and its growing water division, which offers advanced contaminant treatment products and services including ion exchange rosins and granular activated carbon. The air segment is a legacy business with steady demand, while water treatment represents a nascent growth area targeting municipal and industrial water utilities.
Performance Analysis
Birch Tech reported Q2 2026 revenues of approximately $3.8 million, marking a modest increase from $3.3 million in Q2 2025. This growth was driven by increased demand in the air business, supported by a mix of coal plants running amid more extreme weather and higher natural gas prices. Notably, the water segment contributed sales for the first time this year, reflecting initial commercial traction. Despite revenue growth, gross profit remained flat at $1 million quarter-over-quarter, affected by a revenue mix shift away from higher-margin licensing fees recognized in the prior year.
Operating expenses rose significantly, with SG&A increasing to $2.1 million due to elevated legal fees and public company costs following the NYSE America uplisting. R&D spending grew modestly to $0.6 million, focused on advancing water treatment technologies. Other expenses surged to $1.4 million, largely from license and settlement fees absent in the prior year. The net loss widened to $3 million, reflecting continued investment in growth initiatives and legal resolution costs. Adjusted EBITDA loss doubled to $1.9 million, underscoring the current phase of heavy reinvestment.
- Revenue Mix Shift: Transition from licensing income to product sales and water segment revenue impacted margins.
- Expense Growth Reflects Strategic Investment: Increased legal and public company costs alongside R&D for water technology development.
- Cash Position Strengthened: Cash balance rose to $11.8 million with no debt, supporting ongoing growth funding.
Overall, the quarter represents a strategic inflection point as Birch Tech moves from patent enforcement to commercial expansion, with financials reflecting this transition phase.

Strategic Positioning
1. Patent Defense Completion Establishes Durable Competitive Advantage
Birch Tech’s successful conclusion of all Interparte review challenges to its SEA technology patents removes a significant overhang. The permanent barring of further patent validity challenges and dismissal of all petitions reinforce the company’s intellectual property moat, essential for maintaining pricing power and market positioning in emissions control. This legal resolution transitions the company’s focus from enforcement to commercial partnerships and product supply expansion, underpinning future revenue stability.
2. Air Division as a Cash-Generating Legacy Business
The air segment continues to provide steady revenue and cash flow through product supply to licensed coal-fired utilities, despite seasonal fluctuations. Management’s strategy to convert previously unlicensed users into licensees and supply customers aims to deepen recurring revenue streams. The segment’s resilience is supported by stable U.S. coal market conditions and federal support for coal plant operations, extending the operational runway for the SEA platform.
3. Water Business Scaling Through Data-Driven Partnerships
The water division is progressing from initial commercial foundation to growth mode, leveraging data-first design centers and collaborations with engineering firms and environmental consultants. The company’s RSSCT (Rapid Small Scale Column Test) analytical capabilities and expanded ion exchange resin product line address a multi-hundred million dollar market opportunity in municipal and industrial water treatment, including PFAS removal. These design centers serve as profit centers and credibility hubs, facilitating broader market penetration.
4. Carbon Rejuvenation Technology as a Differentiated Growth Driver
Birch Tech is advancing its thermal reactive carbon rejuvenation, which restores granular activated carbon to near-virgin performance levels for PFAS removal. This innovation promises to reduce lifecycle costs for utilities substantially and create a competitive advantage. The company is actively establishing rejuvenation capacity and anticipates material progress updates soon, highlighting a key growth inflection point in sustainable water treatment solutions.
5. Leadership Enhancements Support Execution and Scale
The promotion of Jim Tretl to COO and appointment of a new CFO strengthen operational and financial leadership. With Tretl’s extensive experience in dry bulk material handling and design center operations, Birch Tech is better positioned to scale both air and water platforms while advancing R&D commercialization. This leadership depth aligns with the company’s dual focus on legacy cash flow and emerging growth.
