## Overview

Birchtech Corp. is a U.S.-based specialty activated carbon and environmental technology company focused on mercury emissions capture for coal-fired power plants and emerging water purification applications. Its core business centers on the patented SEA® process, which is used to reduce mercury emissions at lower cost and with less operational disruption than conventional sorbent injection methods. The company is also building a second growth platform in water treatment, including technologies aimed at PFAS and PFOS contamination. In 2024 and 2025, Birchtech expanded its commercialization efforts through new laboratories, design centers, and additional sales and commercialization personnel.

## Customers

Birchtech sells primarily to coal-fired utilities and power plant operators that need mercury emissions solutions to comply with environmental regulations such as MATS. These customers buy the company’s systems and sorbents because they want to reduce mercury emissions without materially hurting plant output or byproduct marketability. The company is also targeting municipal and industrial water utilities, especially those facing compliance pressure around PFAS and broader water quality issues. In addition, Birchtech monetizes its patent portfolio through licensing arrangements with utilities and other counterparties. Its customer base is therefore split between regulated industrial operators seeking compliance solutions and water-sector buyers looking for lower-cost treatment technologies.

- **Coal-fired utilities and power plants** (primary) — Buy mercury capture systems, sorbents, and related technical support to meet emissions rules while preserving plant performance.
- **Water utilities and industrial water operators** (secondary) — Buy or evaluate sorbent-based treatment solutions, testing, and design-center services for PFAS and other contaminants.
- **Patent licensees and litigation counterparties** (secondary) — Enter licensing agreements for use of SEA®-related patents in designated power plants or other applications.
- **Demonstration and consulting customers** (emerging) — Use lab services, contaminant analysis, and carbon performance evaluations to validate treatment performance before larger deployments.

- Coal-fired power plants needing mercury emissions compliance
- Utilities seeking lower-cost alternatives to PAC/BAC sorbent systems
- Municipal water utilities evaluating PFAS and potable-water treatment
- Industrial water operators needing contaminant removal and testing
- Licensees of Birchtech patents for specific plant applications
- Customers buying lab, demonstration, and consulting support

## Geography

Birchtech’s legacy mercury emissions business is centered in North America, which management identifies as the largest market for its emissions technologies. The company’s commercial exposure is therefore tied mainly to U.S. regulatory enforcement, especially the EPA’s MATS framework for coal-fired power plants. It also operates in a cross-border capital markets context, having moved its listing to the Toronto Stock Exchange in late 2024. The new water-treatment initiative is being built from U.S.-based laboratories and design centers, with commercialization expected to expand from that domestic base. No country-level revenue split was disclosed in the provided excerpts.

- North America is the core market for mercury emissions technologies
- U.S. coal-plant regulation is the main demand driver for the legacy business
- Water-treatment commercialization is being built from U.S. labs and design centers
- TSX listing adds Canadian capital-markets visibility, but operations remain U.S.-centric
- No country-level revenue disclosure was provided in the excerpts

## Strategy

Birchtech is trying to defend and monetize its legacy mercury-emissions platform while building a second growth engine in water treatment. Management is investing in design centers and laboratories to generate technical data, define permitting and capex requirements, and shorten the path to commercial thermal reactivation plants. The company is also expanding commercialization capacity through sales leadership and innovation roles focused on potable water and strategic operations. In parallel, it is using patent licensing and litigation-related monetization to support near-term cash generation. The strategy is to convert technical credibility into recurring commercial adoption across both regulated air and water markets.

- **Commercialize water-treatment technologies** (short-term) — This is the main growth initiative and is intended to diversify the company beyond coal-related emissions control.
- **Monetize legacy mercury emissions assets** (short-term) — The existing SEA® platform remains the company’s current revenue base and supports near-term cash generation.
- **Advance thermal reactivation plant commercialization** (medium-term) — Owning or operating reactivation capacity could improve economics and reduce dependence on third parties.
- **Strengthen liquidity through non-operating inflows** (short-term) — The company has disclosed substantial doubt language and is pursuing additional cash sources to fund operations.

- Protect and monetize the mercury emissions franchise through licensing and product sales
- Build water-treatment credibility through design centers, labs, and performance testing
- Use generated data to support future thermal reactivation plant permitting and economics
- Expand sales and commercialization leadership for potable water and strategic operations
- Pursue patent licensing and litigation-related cash inflows to support liquidity

## Risks

Birchtech’s business is exposed to customer concentration and regulatory dependence because its legacy market is tied to coal-fired power plant compliance spending. If environmental rules, enforcement intensity, or coal generation volumes weaken, demand for mercury capture solutions could soften. The company also faces execution risk in water treatment, where it is still in the commercialization and testing phase and must prove performance, permitting, and economics before meaningful scale-up. Liquidity is a material risk, as management disclosed substantial doubt and is relying on litigation proceeds, licensing revenue, and financing to support operations. More generally, the company faces technology adoption risk, patent and litigation uncertainty, and the risk that new water-market demand develops more slowly than expected.

- **Liquidity and going-concern pressure** [high] — Management disclosed substantial doubt and is relying on litigation proceeds, licensing revenue, and financing to fund operations.
- **Regulatory dependence in mercury emissions** [high] — The legacy business depends on U.S. coal-plant emissions regulation and utility compliance spending.
- **Water-treatment commercialization execution** [medium] — The new water platform is still being developed and must prove technical and economic viability before scaling.
- **Patent and litigation monetization uncertainty** [medium] — Expected cash inflows depend on legal outcomes and licensing adoption, which are not guaranteed.

- Dependence on coal-plant environmental compliance spending
- Regulatory risk if MATS enforcement or related rules change
- Commercialization risk in water treatment because the platform is still early
- Liquidity risk due to ongoing losses and reliance on external cash inflows
- Litigation and patent monetization risk tied to uncertain outcomes
- Customer adoption risk if utilities delay capex or prefer competing sorbents

## Accounting

Birchtech’s reported results are sensitive to revenue mix because license fee revenue, product sales, and other revenues such as demonstration and consulting can fluctuate materially by quarter. The company also reports fair value changes on profit share liabilities and notes, which can create non-cash volatility in earnings unrelated to operating performance. R&D expense has increased as lab equipment was placed into service and research on water-treatment sorbents began, so capitalization versus expense timing and the pace of lab buildout affect reported operating loss. Investors should also watch contingent and judgment-related items, including expected litigation proceeds and the fair value of non-recourse profit share liabilities, because these can materially affect liquidity and earnings presentation. Given the company’s small scale and early-stage commercialization efforts, quarterly comparisons can be noisy and heavily influenced by one-time licensing, legal, and development items.

- **Revenue recognition by stream** — Affects reported revenue timing and comparability between periods
- **Fair value measurement of profit share liability** — Can materially affect operating and net income without cash impact
- **R&D expense recognition** — Raises reported losses during commercialization buildout
- **Contingent litigation proceeds** — Can affect cash flow expectations and balance sheet strength

- Revenue mix is uneven across license fees, product sales, and other services
- Demonstration, consulting, and equipment sales are small and can be lumpy
- Fair value changes in profit share liabilities can create non-cash earnings volatility
- R&D expense is rising as water-treatment labs and equipment are put into service
- Litigation-related receivables and judgments may affect liquidity and reported assets
- Quarterly results can swing with licensing timing and legal settlements
