PFAS Regulations And Water Media Expansion Will Drive Long-Term Earnings Upside

Catalysts

About Birchtech

Birchtech develops and commercializes patented activated carbon technologies that reduce air emissions and remove emerging contaminants from water.

What are the underlying business or industry changes driving this perspective?

• Expansion of long term SEA technology licenses and the shift of former infringers into product supply customers should steadily convert episodic legal wins into recurring air division consumables revenue and support structurally higher gross margins.
• Stabilization of U.S. coal generation, alongside policy support for emissions controlled baseload power, provides a longer operating runway for existing utility customers. This extends the life of high margin air contracts and sustains earnings visibility.
• Rapidly tightening PFAS standards across dozens of states and at the federal level is driving an influx of testing and design work through engineering partners. This positions Birchtech's data driven RSSCT services to scale into a repeat revenue stream with attractive service margins.
• Commercialization of proprietary granular activated carbon and the build out of reactivation capabilities should allow Birchtech to capture higher value media sales in the water market. This expands the consolidated revenue base and improves blended net margins as volumes ramp from 2026 onward.
• A potential nine figure cash inflow from the pending patent judgment, combined with a debt free balance sheet, creates optionality to fund water infrastructure projects and joint ventures without material dilution. This may accelerate earnings growth while preserving strong returns on invested capital.

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming Birchtech's revenue will grow by 34.2% annually over the next 3 years.
• Analysts assume that profit margins will increase from -19.5% today to 14.1% in 3 years time.
• Analysts expect earnings to reach $6.6 million (and earnings per share of $0.06) by about December 2028, up from $-3.8 million today.
• In order for the above numbers to justify the price target of the analysts, the company would need to trade at a PE ratio of 54.8x on those 2028 earnings, up from -23.3x today. This future PE is greater than the current PE for the US Commercial Services industry at 23.4x.
• Analysts expect the number of shares outstanding to grow by 0.66% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 6.96%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• Birchtech remains heavily exposed to U.S. coal fired power. If long term secular decarbonization resumes after the current exemptions expire in 2029, plant closures or reduced utilization could shrink demand for SEA based sorbents and new licenses, pressuring revenue and net margins over time.
• The pending patent judgment and associated profit share liability are one time and uncertain. An adverse or delayed court outcome would remove a major source of expected growth capital, limiting the pace of investment in water infrastructure and constraining future earnings.
• Scaling granular activated carbon production and reactivation is capital intensive and operationally complex. Execution missteps similar to those experienced by other industry players could drive cost overruns and delays, eroding the high margin profile anticipated for the water segment and compressing consolidated margins.
• Competition and evolving PFAS regulations across dozens of states may favor larger incumbents or alternative technologies. If utilities select other solutions despite robust demand, Birchtech's early purchase orders may not translate into the expected broad adoption, resulting in lower long term water revenues and subdued earnings growth.
• The recent profitability and strong gross margin are driven in part by high margin licensing revenue. As the mix shifts toward consumables and service contracts, or if license renewals are fewer than expected, the structural margin uplift may prove temporary, leading to weaker net income and earnings than current expectations imply.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of $3.0 for Birchtech based on their expectations of its future earnings growth, profit margins and other risk factors.
  
• In order for you to agree with the analysts, you'd need to believe that by 2028, revenues will be $46.9 million, earnings will come to $6.6 million, and it would be trading on a PE ratio of 54.8x, assuming you use a discount rate of 7.0%.
  
• Given the current share price of $0.91, the analyst price target of $3.0 is 69.7% higher.
  
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
