Current report

Payroll and benefits expense increased by approximately $1.8 million for the three months ended September 30, 2026 compared to the same period in 2025, primarily due to higher incentive compensation expense. The increase was primarily attributable to higher accrued incentive compensation expense during the three months ended September 30, 2026, resulting from expected company performance relative to established performance targets. Accrued incentive compensation expense was lower during the three months ended September 30, 2025, due to expected company performance relative to the applicable performance targets, further contributing to the increase between periods.

Current report

Other income decreased for the three months ended September 30, 2026 compared to the corresponding quarter in 2025 primarily due to a gain from insurance proceeds received during the three months ended September 30, 2025.

Current report

Comparison of the Nine Months Ended September 30, 2026 and 2025

Current report

Payroll and benefits expense increased by approximately $2.2 million for the nine months ended September 30, 2026 compared to the corresponding period in 2025, primarily due to severance expense related to the departure of three members of our executive leadership team and employees terminated at our Corbin Facility, which contributed approximately $0.7 million of additional expense during the nine months ended September 30, 2026. Additionally, incentive compensation expense increased by approximately $0.5 million for the nine months ended September 30, 2026 compared to the corresponding period in 2025 due to expected company performance relative to established performance targets. Stock-based compensation expense increased by $0.4 million between periods, driven by inducement awards granted to new executives, as well as the acceleration of outstanding awards related to the departure of previous executives, not included in the severance expense above. The remaining increase relates to employer payroll tax expense associated with other increases, as well as increases in other benefits expenses.

Previous wording

Our primary products are comprised of AC, which is produced from a variety of carbonaceous raw materials. Our AC products include both powdered activated carbon ("PAC") and granular activated carbon ("GAC"). Additionally, we own the Five Forks Mine, a lignite mine located in Saline, Louisiana, that currently supplies the primary raw material for the manufacturing of our products. We also control bituminous coal waste reserves and own a manufacturing facility, both located in Corbin, Kentucky (the "Corbin Facility"), and a process to recover and purify the bituminous coal fines. Using the Corbin Facility's manufacturing process, we convert coal waste into a purified, microfine carbon powder ("Corbin Wetcake") for use in high-value applications. On August 6, 2025, we announced that we had successfully commissioned our Red River Plant’s GAC Facility (the "GAC Facility") and produced our first commercial volumes of on-specification GAC product. However, after initial production runs, in December 2025, it became clear that ramp-up to nameplate capacity could not be accomplished without further modifications to the existing systems because of design flaws in our GAC Facility. In March 2026, we decided to pause GAC production, continue to idle the Corbin Facility as a cost saving measure, and launch an engineering and production process optimization review, including an evaluation of potential GAC Facility design modifications and production economics at different scales. Additionally, we now expect to transition away from using Corbin Wetcake for the production of our GAC products to a bituminous coal feedstock with proven performance.

Our AC products include both powdered activated carbon ("PAC") and granular activated carbon ("GAC"). Additionally, we own the Five Forks Mine, a lignite mine located in Saline, Louisiana, that currently supplies the primary raw material for the manufacturing of our products at our facility in Coushatta, Louisiana (the "Red River Plant"). We also control bituminous coal waste reserves and own a manufacturing facility, both located in Corbin, Kentucky (the "Corbin Facility"), and a process to recover and purify the bituminous coal fines. Using the Corbin Facility's manufacturing process, we are able to convert coal waste into a purified, microfine carbon powder ("Corbin Wetcake") for use in high-value applications.

Previous wording

We continue to believe that Corbin Wetcake has the potential to enable us to access new markets and applications. We intend to secure customer interest in Corbin Wetcake as an additive into other markets, such as a component for asphalt, or for use in the purified coal and synthetic graphite industries. In addition, we are exploring uses for certain rare earth minerals and critical elements that can be contained within material from the manufacturing process at our Corbin Facility for further recovery and concentration by others. These applications are currently in early stages of proof-of-concept testing or preliminary customer testing.

These applications are currently in early stages of proof-of-concept testing or preliminary customer testing.

Previous wording

Drivers of demand and current key factors affecting our profitability are sales of our AC products to the APT market. Our operating results are influenced by: (1) changes in our manufacturing production and sales volumes; (2) changes in price and product mix; (3) changes in coal-fired dispatch and electricity power generation sources; (4) changes in demand for contaminant removal within water treatment facilities; (5) changes in environmental regulations; and (6) state or municipal approval and customer acceptance of our new products.

Current wording

Demand for our products, as well as key factors that affect our profitability and operating results are influenced by: (1) changes in our manufacturing production and sales volumes; (2) changes in price and product mix; (3) changes in coal-fired dispatch and electricity power generation sources; (4) changes in demand for contaminant removal within water treatment facilities; (5) changes in environmental regulations; and (6) state or municipal approval and customer acceptance of our new products.

Previous wording

For the three and six months ended June 30, 2026, we experienced an increase in demand for our products from certain coal-fired dispatch and electricity power generation customers compared to the same period in 2025. This was primarily due to the year-to-date impact of moderate to severe temperatures during the winter and summer seasons, resulting in higher demand for power generation, and the impact of steady natural gas prices, resulting in several large utility customers opting to use coal versus natural gas as a primary source for power generation. Additionally, demand for power generation has grown and continues to grow driven by macroeconomic trends, such as increased consumption related to data and computer centers, electric vehicles, and other large-scale power consumers. We expect that natural gas prices will remain relatively consistent through 2026 at an elevated level due to increased demand for liquid natural gas exports, and conflict in the Middle East impacting supply, partially offset by increases in anticipated natural gas inventory levels.

Current wording

For the three and nine months ended September 30, 2026, we experienced an increase in demand for our products from certain coal-fired dispatch and electricity power generation customers compared to the same period in 2025. Demand for power generation has grown and continues to grow driven by macroeconomic trends. We expect that natural gas prices will remain relatively consistent through 2026 at elevated levels due to increased demand for liquified natural gas exports, and conflict in the Middle East impacting supply, partially offset by increases in anticipated natural gas inventory levels. Furthermore, under rules promulgated by the United States Environmental Protection Agency (the “EPA”), beginning April 2027 public water systems will be required to report the level of PFAS contamination in their water with the goal of reducing such levels to four parts per trillion by 2029 or 2031. We expect that the requirement to publish PFAS contamination may have a material impact on our results of operations in the near term as public water systems utilize our products, such as our PAC for PFAS™ product, to reduce the level of PFAS present in their water.

Previous wording

The decision to pause GAC production, continue idling the Corbin Facility as a cost saving measure, and launch an engineering and production process optimization review was made in March 2026, following the review of independent testing results received in January 2026. This testing demonstrated that the thermal oxidizer in place could only support approximately 15 million pounds of annual GAC production, and would require additional modifications to achieve our original design capacity of 25 million pounds or higher. Our analysis indicates that a 15 million pound per year scenario on a stand-alone basis does not provide sufficient returns to make it economically attractive. The optimization review remains ongoing and is expected to determine production scale, capital requirements, and return profiles before we commit to additional investment in our GAC Facility. We have since expanded the optimization review to include a broader operational assessment of our overall business, which has focused on maximizing furnace throughput and reducing unit costs for each of our products, including our PAC and GAC products.

Current wording

The decision to pause GAC production, continue idling the Corbin Facility as a cost saving measure, and launch an engineering and production process optimization review was made in March 2026, following the review of independent testing results received in January 2026. This testing demonstrated that the thermal oxidizer in place for processing off-gas treatment could only support approximately 15 million pounds of annual GAC production, and would require additional modifications to achieve our original design capacity of 25 million pounds or higher. Our analysis indicates that a 15 million pound per year scenario on a stand-alone basis does not provide sufficient returns to make it economically attractive.

Previous wording

Due to the issues described above, we do not expect GAC production in fiscal year 2026 or 2027.

Current wording

This strategic optimization review is effectively complete, and the preferred design, estimated costs, and timing associated with restarting and ramping our GAC Facility up to our target capacity have been determined. As discussed above, we continue to pause production at our GAC Facility and will proceed with further investment when the returns are economically attractive. Because of this, and due to the issues described above, we do not expect GAC Facility production in fiscal year 2026 or 2027.

Previous wording

For the three and six months ended June 30, 2026, we recognized net loss of $0.7 million and $1.9 million, respectively, compared to net loss of $2.4 million and $2.4 million, respectively, for the three and six months ended June 30, 2025. The most significant factors impacting results between periods for the three months ended June 30, 2026 and June 30, 2025 were increases in revenue due to increased pricing and demand for our products, offset by increases in severance expense related to the previously disclosed departures of certain members of our executive team.

Current wording

For the three and nine months ended September 30, 2026, we recognized net income of $2.5 million and $0.6 million, respectively, compared to net loss of $0.9 million and $3.3 million, respectively, for the three and nine months ended September 30, 2025. The most significant factors impacting results between periods for the three months ended September 30, 2026 and September 30, 2025 were increases in revenue due to demand for our products, partially offset by increases in severance expense related to the previously disclosed departures of certain members of our executive team.

The current year period to prior year period comparisons of financial results may not be indicative of future financial results.

Previous wording

For the three months ended June 30, 2026, revenue increased from the comparable quarter in 2025 primarily driven by the impact of increased pricing, which contributed additional revenues of $1.3 million, as well as higher sales volumes of our AC products, which contributed additional revenues of approximately $1.0 million of the total revenue increase. These increases were partially offset by a decrease in revenue attributable to lower sales of our chemicals products during the three months ended June 30, 2026, which caused revenue to decrease by $1.1 million from the comparable quarter in 2025. The increases due to higher pricing and volumes sold were primarily attributable to sales to customers in the power-generation market, driven by seasonal electricity demand. Notably, our revenues continue to be impacted by electricity demand driven by seasonal weather and power generation needs.

Current wording

For the three months ended September 30, 2026, revenue increased from the comparable quarter in 2025 primarily driven by higher sales volumes of our AC products, which contributed additional revenues of approximately $3.8 million. Additionally, higher sales of our other chemicals products during the three months ended September 30, 2026 contributed an increase in revenue of $0.2 million from the comparable quarter in 2025. These increases were partially offset by a decrease in revenue attributable to a decrease in the average selling price between periods and a decrease due to product mix sold, which offset $0.6 million and $0.2 million, respectively, of the increase. The increase due to volumes sold was primarily attributable to sales to customers in the power-generation market, driven by seasonal electricity demand. Our revenues continue to be impacted by electricity demand driven by seasonal weather and power generation needs.

Previous wording

During the three months ended June 30, 2026, our gross margin was favorably impacted by both the pause in production at our Corbin Facility, which we idled indefinitely as of December 2025, and improved mix during the three months ended June 30, 2026 due to lower sales of our lower-margin chemical products compared to the same period in 2025. These favorable impacts to gross margin were partially offset by an increase in our costs per unit during the three months ended June 30, 2026, which were primarily due to increases in salaries and wages of our operations personnel and utilities costs. These factors resulted in the majority of the approximately $0.7 million decrease in Cost of revenue, exclusive of depreciation and amortization for the three months ended June 30, 2026 compared to the comparable quarter in 2025.

Current wording

During the three months ended September 30, 2026, our gross margin was favorably impacted by the cost savings associated with the pause in production at our Corbin Facility, which we idled indefinitely as of December 2025. Additionally, our gross margin was favorably impacted by lower maintenance and outside service expenses during the three months ended September 30, 2026, as the comparable period in 2025 included costs attributable to planning and production of our GAC products. These favorable impacts to gross margin were partially offset by an increase in the salaries and wages of our operations personnel, as well as increased utilities costs, for the three months ended September 30, 2026. These factors were primarily responsible for the approximately $1.9 million decrease in Cost of revenue, exclusive of depreciation and amortization for the three months ended September 30, 2026 compared to the comparable quarter in 2025.

Previous wording

We expect that revenue will continue to be positively impacted by demand for our PAC products. As we have paused production of our GAC products at our Red River Plant, we expect that gross margin will continue to improve as the impact of fixed production costs related to our GAC products on our gross margin lessens. Further, as we conduct a comprehensive engineering and production process optimization review related to our GAC products, we expect to improve the operational efficiency of PAC production at our Red River Plant and improve our product mix to higher margin products.

Current wording

We expect that revenue will continue to be positively impacted by demand for our PAC products, including increased demand related to the use of PAC for PFAS treatment. As we have paused production at our GAC Facility at our Red River Plant, we expect that gross margin will continue to improve relative to 2025 as the impact of fixed production costs related to our GAC Facility on our gross margin lessens.
