Risk or Challenges
GAC Production Challenges: The company has paused GAC production due to significant technical and design challenges, including original design flaws, moisture content issues, inefficient design configurations, and off-gas system inefficiencies. These issues have led to cost overruns, delays, and operational inefficiencies.
Economic Viability of GAC: Producing 15 million pounds of GAC is not economically viable due to lower margins at this production level. The business case requires achieving at least 25 million pounds of production, but scaling to this level involves unresolved cost and technical uncertainties.

Leadership and Operational Changes: Significant changes in leadership and operational roles have been made to address ongoing challenges, including the appointment of a new Senior VP of Operations and other key personnel changes. These changes indicate prior leadership and operational inefficiencies.

Supply Chain and Feedstock Challenges: The transition to purchased bituminous coal feedstock was necessitated by challenges with the Corbin Wetcake feedstock, including high moisture content and handling difficulties, which exacerbated production inefficiencies.
Regulatory and Market Risks: While the GAC market fundamentals remain strong, delays in production and scaling could impact the company's ability to capitalize on market opportunities, including PFAS-related demand.

Key Q&A
Q:Is there anything that would prevent the company from pursuing GAC given the demand and market conditions?
A:No, the company sees no reasonable alternative but to pursue GAC due to strong market fundamentals, extreme undersupply, rising pricing, and barriers to entry for competitors.
Q:What is the visibility into PAC contracts and are there any regulatory uncertainties?
A:The company has excellent visibility with 96% of targeted volumes for 2026 and 75% for 2027 already contracted. There is no regulatory uncertainty affecting the PAC business as existing regulations remain unchanged.
Q:What is the free cash flow outlook for the year and any balance sheet considerations?
A:The company expects to generate free cash flow of $4 million to $8 million after accounting for CapEx and interest costs. The biennial plant turnaround scheduled for April will cost $3 million, included in the CapEx guidance.
Q:Does the company have capacity to meet potential upside demand for PAC?
A:Yes, the company has excess capacity at Red River and can expand PAC volumes to meet increased demand from factors like high natural gas prices, increased electricity demand, and weather-related power demand.
Q:What is the status of the thermal oxidizer and off-gas system issues?
A:The company initially planned to spend $8-10 million on a thermal oxidizer but found that a complete air quality control system is needed. This includes additional components like a water quencher, heat exchanger, and wet scrubber. The company is using this optimization period to refine recommendations and determine final timing and cost.
Q:Is the company comfortable with the switch to third-party feedstock?
A:Yes, the company has extensively tested over 55 potential feedstocks, narrowed it down to 5, and is confident in the switch and resulting product quality.
Q:What are the pricing expectations for PAC ASP growth?
A:The company expects PAC ASP growth of about 1% at the midpoint, with price increases moderating from the double-digit pace of previous quarters. Growth will also come from expanding into more value-added markets.
Q:What is the progress on alternative applications for Corbin Wetcake?
A:The most advanced application is asphalt emulsion, with testing progressing to the next round. Other applications like synthetic graphite and graphene are longer-term and still in research stages.
Q:Are there tariff benefits for domestic producers like Arq, and are they reflected in the guidance?
A:The guidance does not include any benefits from tariffs. The company’s guidance reflects steady-state business without considering potential tariff advantages.
Q:How does the company view its contract volume visibility for 2027 and 2028?
A:The company views its contract volume visibility as typical, with a high renewal rate of 86% or more. It expects similar visibility in future years.

A:The company is confident in its position but cannot comment on the particulars of active litigation. It is still in a wait-and-see mode.
Q:Review of Unclear Management Responses
