APPENDIX

Non-GAAP Reconciliation Adjusted EBITDA The successor columns represent the combined financial information of Charah and Allied for the period from January 13, 2017 through September 30, 2017 and January 1, 2018 through September 30, 2018 as applicable, as reflected in our financial statements included elsewhere in this Quarterly Report. The predecessor and successor columns together represent our accounting Predecessor for purposes of this Quarterly Report. The predecessor columns represents the financial information of Charah for the period from January 1, 2017 through January 12, 2017 as reflected in our audited financial statements included elsewhere in this Quarterly Report. The predecessor and successor columns together represent our accounting Predecessor for purposes of this Quarterly Report. Represents non-recurring legal costs and accruals associated with outstanding legal claims, which amounts are not representative of legal costs that we historically incur in the ordinary course of our business. Represents non-recurring start-up costs associated with the startup of Allied and our nuclear services offerings, including the setup of financial operations systems and modules, pre-contract expenses to obtain initial contracts and the hiring of operational staff. Because these costs are associated with the initial setup of the Allied business to initiate the operations involved in our nuclear services offerings, these costs are non-recurring in the normal course of our business. Primary components include a change in charitable giving and other business expense policies associated with the BCP investment. Non-acquired business line item adjusts for a legacy operation of Charah, LLC that was transferred to a stockholder of CEP Holdings in January 2017 prior to the BCP investment. Adjusted EBITDA margin is a non-GAAP measure that represents the ratio of Adjusted EBITDA to total revenues (which for the year ended December 31, 2016 were less revenues ($5,045) of a non-acquired business line). We use Adjusted EBITDA margin to measure the success of our businesses in managing our cost base and improving profitability.

Routine Operations RECURRING SERVICES NEED Byproduct Sales WHAT Recycling of recurring and contracted volumes of coal-fired power generation waste byproducts WHY Coal ash can be recycled as a high-quality, cost-effective raw material substitute (most commonly cement) On-site Landfill Operations WHAT Load, haul and place non-sellable coal-ash at a disposal location either onsite or elsewhere WHY Remove the burdens associated with coal-ash management at the utility level Remediation & Compliance Services SIGNIFICANT GROWTH OPPORTUNITY WHAT Manage the design, operation, remediation, closure and construction of on-site ash ponds and landfills WHY Conserve virgin resources, reduce greenhouse gas emissions, decrease landfill disposal and conserve water Coal-Fired End-Market Services WHAT Coordinate all aspects of the ash management operation, from processing to facilitating an economical disposal or beneficial use WHY Coal ash management is mission-critical to the daily operations of power plants as they generally only have 2-3 days of on-site storage capacity Embedded Power Plant Presence Coal Ash Management Sellable Ash Environmental Compliance Requirement Non-Sellable Ash Daily Production Coal Power Plant Services

Coal & Nuclear Are Not Going Away Source: Energy Information Administration After a Decade of Slowing, Electricity Use from Coal and Nuclear is Expected to Remain Steady Through 2050 history projections 2017 Electricity Generation from Coal & Nuclear Billion Kilowatthours Only 1 of the 37 coal power plants currently serviced by Charah is scheduled to close between now and 2030 Only 1 of the 22 nuclear reactors currently serviced by Charah is scheduled to close between now and 2025 Coal & Nuclear Currently = ~50% of Total U.S. Energy Production

Third Quarter 2018 Regulatory Updates U.S. Court of Appeals for the Fourth Circuit Ruled all unlined coal ash ponds must be closed, including clay-lined and legacy inactive ponds, which were previously excluded from the EPA CCR regulations Significantly increases the addressable market and further validates the requirement for remediation EPA CCR Phase 1 Revisions Extends closure deadline to October 2020 for some active ponds with leaks or inadequate separation between bottom of pond and ground water table (estimated to affect less than 15% of total ponds) May shift timeline for some projects or customers

Third Quarter 2018 Business Impacts Update Commentary Takeaway Expected Early Completion of Brickhaven Contract As result of change in North Carolina law, Duke Energy expected to discontinue ash deliveries to Brickhaven once Riverbend project is completed (~Dec. 2018) Contract includes financial protections providing for recovery of project development costs and expected site closure costs No impact on other current North Carolina projects Nuclear Services Revenue Shortfall Result of market pressures within the nuclear industry to reduce costs and increase competitiveness Coupled with Charah’s ability to bring outages in ahead of schedule Resulting in shorter outages and reduced discretionary spending Revenue and profit from future years pulled forward into 2018 Payment expected in first half of 2019 Expected reversal of significant working capital balances Debt reduction Increased capital allocation flexibility from additional cash available Minimal EBITDA impacts due to low-margin nature of business In 2018, EBITDA impacts offset by strong performance in other segments
