Birchtech's Patent Win Sets the Stage, but Collections and Execution Loom
A seven-year IPR saga ends, leaving a $78M judgment on appeal and a pivot to water—yet the stock keeps sliding.
BCHT · Earnings Call · 2026-08-13
The $78M question
After seven years of patent litigation, Birchtech's CEO declares victory:
Every petition filed with the Patent Trial and Appeal Board against our patented SEA technologies have now been dismissed, removed prior to institution or resolved, and the parties previously involved are permanently barred from bringing further patent validity challenges.
That milestone, achieved in June, closes the IPR chapter and leaves the company with a portfolio of enforced patents and a history of collecting roughly $37 million in license fees and settlements. The true prize, however, is the $78 million-plus final judgment entered by the Delaware court in December 2025. The defendants have appealed without posting a bond; interest accrues daily. CFO Mike Mioska highlighted the balance-sheet angle: “Cash as of June 30, 2026, totaled $11.8 million with no debt” — Michael Mioska, Chief Financial Officer · 2026-08-13 and added that the only meaningful liability is a $7.3 million profit-share obligation tied to collecting that judgment. The jump from $2.2 million in cash at the end of 2025 suggests a recent capital raise, which may be why shares are down 33% over the past 90 days despite the positive news.
Air: conversion, not litigation
The company's core activated carbon business remains the self-funding engine. Second-quarter revenue rose to $3.8 million from $3.3 million, but gross profit was flat as licensing gave way to product sales. Management's script is to convert utilities that once faced patent litigation into long-term supply customers. Rick MacPherson says: “I do expect that we'll see an increase starting in the second half of this year. I do expect that we'll see a significant increase in the actual product supply revenue on the air side for 2026 over 2025” — Richard MacPherson, Chief Executive Officer · 2026-08-13 He declined to quantify the target, a shift from the March guidance when he said: “we will be in excess of $20 million on the air side for 2026” — Richard MacPherson, Chairman and CEO · 2026-03-31 The pace depends on when contracts come up for renewal. The company says it has settled all but one outstanding case, and that remaining defendant represents meaningful supply potential: “there are a couple of very large defendants in the Iowa case that have significant product supply potential” — Richard MacPherson, Chairman and CEO · 2026-03-31 (from the March call).
Water: the growth bet
The water division is the future. The company has launched Ion exchange rosins aimed at a $200 million-plus addressable market, built RSSCT testing design centers, and is developing carbon rejuvenation technology that could dramatically reduce PFAS treatment costs. Management expects to announce meaningful progress in Q3: “We are getting close to some significant decisions on that front through the work that we've been doing over these past few months” — Richard MacPherson, Chief Executive Officer · 2026-08-13 The regulatory tailwind is strong: PFAS removal mandates are driving utilities to test and adopt new solutions, and Birchtech's data-first approach positions it alongside engineering firms. The company is also expanding its SEA-IX product line to address boron and heavy metals.
Beyond the product roadmap, the leadership team has been strengthened with Mike Mioska joining as CFO in May and Jim Trettel promoted to COO, bringing decades of experience in dry bulk handling and design-center operations. Trettel's expertise is expected to be pivotal in scaling both air and water platforms, especially as Birchtech moves toward commercializing carbon rejuvenation.
Financial reality check
The fundamentals are still a turnaround. Total Revenue stood at $4M in the latest filed quarter, but Effective Net Cash masks the need for ongoing dilution. The net loss widened to $3M in Q2, driven by legal fees and investment in water. The stock's recent downtrend suggests the market is not yet convinced that the judgment will be collected or that the water business will scale. If the appeal succeeds or the company secures large offtake agreements, the upside is enormous relative to a market cap near $37 million. But for now, this is a wait-and-see story. The next quarter's promised "hard news" could be the catalyst.
