Item 8.01

Other Events.

As previously disclosed, on August 20, 2024, Arch Resources, Inc., a Delaware corporation (“Arch”), entered into an Agreement and Plan of Merger (as it may be amended from time to time, the “merger agreement”) with CONSOL Energy Inc., a Delaware corporation (“CONSOL”), and Mountain Range Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of CONSOL (“Merger Sub”). The merger agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into Arch (the “merger”), with Arch continuing as the surviving corporation in the merger and a wholly owned subsidiary of CONSOL. The merger agreement was unanimously approved by the board of directors of each of Arch and CONSOL.

In connection with the merger, CONSOL filed a Registration Statement on Form S-4 (as amended, the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”) that also includes a prospectus of CONSOL and a joint proxy statement of Arch and CONSOL, as amended. The Registration Statement was declared effective on November 26, 2024, after which Arch filed a definitive joint proxy statement and CONSOL filed a final prospectus. Arch and CONSOL commenced mailing of the definitive joint proxy statement/prospectus to their respective stockholders on or about November 26, 2024.

Following the announcement of the merger agreement, as of the date of this Current Report on Form 8-K, three lawsuits challenging the merger have been filed (each, a “Lawsuit” and, collectively, the “Lawsuits”). The first Lawsuit, captioned Robert Garfield v. James Brock et al. (Case No. 2024-CV-08379), was filed in the Supreme Court of Pennsylvania for Dauphin county on December 12, 2024. The second Lawsuit, captioned Nathan Turner v. Arch Resources, Inc. et al. (Case No. 659683/2024), was filed in the Supreme Court of the State of New York for the county of New York on December 16, 2024. The third Lawsuit, captioned Michael Lewis v. Arch Resources, Inc. et al. (Case No. 659716/2024), was filed in the Supreme Court of the State of New York for the county of New York on December 17, 2024. In addition, Arch and CONSOL received demand letters from counsel representing individual stockholders of Arch and CONSOL, respectively (the “Demand Letters” and, together with the Lawsuits, the “Matters”). The Matters each generally allege that the joint proxy statement/prospectus filed by Arch and CONSOL, and their respective directors and officers, in connection with the proposed merger contains false and misleading statements and/or omissions, and demand that the parties issue corrective disclosures.

Arch and CONSOL believe that the allegations asserted in the Matters are without merit and additional disclosures are not required or necessary under applicable laws. However, in order to avoid the risk that the Matters delay or otherwise adversely affect the merger, and to minimize the cost, risk and uncertainty inherent in litigation, and without admitting any liability or wrongdoing, Arch and CONSOL have agreed to voluntarily supplement the joint proxy statement/prospectus as described in this Current Report on Form 8-K. Arch and CONSOL deny that they have violated any laws or breached any duties to Arch’s stockholders or CONSOL’s stockholders, as applicable. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Arch and CONSOL specifically deny all allegations in the Matters that any additional disclosure was or is required. To the extent that the information set forth herein differs from or updates information contained in the joint proxy statement/prospectus, the information set forth herein shall supersede or supplement the information in the joint proxy statement/prospectus. All page references are to pages in the joint proxy statement/prospectus, and terms used below, unless otherwise defined, have the meanings set forth in the joint proxy statement/prospectus. For clarity, new text within restated disclosures from the joint proxy statement/prospectus is highlighted with bold, underlined text, while deleted text is bold and stricken-through.

Supplemental Disclosures to Joint Proxy Statement/Prospectus in Connection with the Matters

The additional disclosures (the “supplemental disclosures”) in this Current Report on Form 8-K supplement the disclosures contained in the joint proxy statement/prospectus and should be read in conjunction with the disclosures contained in the joint proxy statement/prospectus, which should be read in its entirety. To the extent that information set forth in the supplemental disclosures differs from or updates information contained in the joint proxy statement/prospectus, the information in this Current Report on Form 8-K shall supersede or supplement the information contained in the joint proxy statement/prospectus. Page references in the below disclosures are to the joint proxy statement/prospectus, and defined terms used but not defined herein shall have the meanings set forth in the joint proxy statement/prospectus.

The fourth paragraph on page 84 under the heading “Background of the Merger” is amended as follows:

Also on August 16, 2024, Messrs. Lang, Brock and Thakkar met to discuss and agree upon the pro forma headquarters, name and management team of the combined company as well as other governance matters. At this meeting, it was discussed that Mr. Lang would serve as Chief Executive Officer of the combined company and Mr. Brock would serve as Executive Chair of the combined company. In addition, between August 16, 2024, and August 18, 2024, Messrs. Lang, Brock and Navarre, as well as representatives of PWP and Moelis, had several conversations regarding the proposed exchange ratio to be used in the possible transaction between Arch and CONSOL. During such discussions, Messrs. Lang and Navarre and representatives of PWP each proposed using an exchange ratio based on a trailing volume-weighted-average price of the companies rather than a current trading price.

The following paragraph is added after the fourth paragraph on page 84 under the heading “Background of the Merger”:

On August 16, 2024, representatives of Moelis provided customary relationship disclosures to the CONSOL board with respect to CONSOL and Arch, which included disclosure that as of the date of such disclosure Moelis did not own or trade any securities of CONSOL or Arch and that none of the Moelis managing directors working on the potential transaction owned any securities of CONSOL or Arch.

The penultimate paragraph on page 94 under the heading “Discounted Cash Flow Analysis—Standalone—CONSOL” is amended as follows:

Moelis utilized a range of discount rates of 9.25% to 12.00% based on an estimated range of CONSOL’s weighted average cost of capital (the “WACC”). The estimated WACC range reflected a derived cost of equity range using the capital asset pricing model (“CAPM”) (a) a risk-free rate based on 20-year U.S. government bonds, (b) a selected range of unlevered betas and debt to total capitalization ratios informed by the Selected Companies described below, (c) an equity risk premium and (d) a size premium. Moelis used the foregoing range of discount rates to calculate estimated present values as of June 30, 2024 of (i) estimated unlevered free cash flows of CONSOL for the second half of the calendar year ending December 31, 2024 through the end of the calendar year ending December 31, 2028 (in each case, discounted using a mid-year discounting convention) and (ii) estimated terminal values derived by applying a range of selected terminal multiples of 4.00x to 5.00x to CONSOL’s terminal year LL-Adjusted EBITDA (which was equal to LL-Adjusted EBITDA for the calendar year ending December 31, 2028).

The first full paragraph on page 95 under the heading “Discounted Cash Flow Analysis—Standalone—CONSOL” is amended as follows:

In calculating the implied equity value of CONSOL, Moelis removed the income statement and free cash flow impacts of the legacy liabilities for CONSOL (which CONSOL management estimated to be $557 million on a tax-affected and net of assets basis) and treated these liabilities as net debt adjustments.

The fourth full paragraph on page 95 under the heading “Discounted Cash Flow Analysis—Standalone—Arch” is amended as follows:

Moelis utilized a range of discount rates of 9.25% to 12.00% based on an estimated range of Arch’s WACC. The estimated WACC range reflected a derived cost of equity range using CAPM (a) a risk-free rate based on 20-year U.S. government bonds, (b) a selected range of unlevered betas and debt to total capitalization ratios informed by the Selected Companies described below, (c) an equity risk premium and (d) a size premium. Moelis used the foregoing range of discount rates to calculate estimated present values as of June 30, 2024 of (i) estimated unlevered free cash flows of Arch for the second half of the calendar year ending December 31, 2024 through the end of the calendar year ending December 31, 2028 (in each case, discounted using a mid-year discounting convention) and (ii) estimated terminal values derived by applying a range of selected terminal multiples of 4.50x to 5.50x to Arch’s terminal year LL-Adjusted EBITDA (which was equal to LL-Adjusted EBITDA for the calendar year ending December 31, 2028).

The last sentence of the first paragraph on page 96 under the heading “Discounted Cash Flow Analysis—Standalone—Arch” is amended as follows:

Moelis also removed the income statement and free cash flow impacts of the legacy liabilities for Arch (which CONSOL management estimated to be $244 million on a tax-affected and net of assets basis) and treated these liabilities as net debt adjustments.

The third and fourth full paragraphs on page 101 under the heading “Other Information—Equity Research Share Price Targets” is amended as follows:

Moelis reviewed publicly available consensus estimate stock price targets for shares of CONSOL common stock published as provided by Bloomberg or Wall Street research reports as of August 9, 2024, which ranged from $103.00 to $120.00 per share (which implied a range of equity values for CONSOL of $3,078 million to $3,586 million). Moelis compared this range with the closing trading price of the CONSOL common stock of $95.81 per share on August 19, 2024 (which implied an equity value of CONSOL of $2,863 million).

Moelis also reviewed publicly available consensus estimate stock price targets for shares of Arch common stock as provided by Bloomberg or Wall Street Research reports as of August 19, 2024, which ranged from $155.00 to $200.00 per share (which implied a range of equity values for Arch of $2,862 million to $3,693 million). Moelis compared this range with the closing trading price of the Arch common stock of $127.00 per share on August 19, 2024 (which implied an equity value of Arch of $2,345 million).

The third and fourth paragraphs under the heading “Opinion of Perella Weinberg Partners LP, Arch’s Financial Advisor—Summary of PWP’s Financial Analyses—Selected Public Companies Analysis” on pages 110 through 111 are amended and restated as follows:

The financial information reviewed included enterprise value as a multiple of normalized adjusted EBITDA, which we calculate as the average of actual 2023, estimated 2024, and estimated 2025 adjusted EBITDA. and which wWe refer to this as “Normalized EBITDA,.” and Additionally, we considered estimated 2024 and 2025 adjusted EBITDA, which we refer to as “2024E EBITDA” and “2025E EBITDA,” respectively,. These estimates are based on median broker consensus estimates and, with respect to Arch and CONSOL, the Arch Forecasts and CONSOL Forecasts, with balance sheet items in each case as of June 30, 2024. The low to high of observed following table summarizes EV / Normalized EBITDA multiples, for the selected public companies was 2.9x to 4.5x with a median of 4.3x. The low to high of observed EV / 2024E EBITDA multiples for the selected public companies was 3.3x to 5.8x with a median of 4.6x. The low to high of observed and EV / 2025E EBITDA multiples for of each of the selected public companies was 3.5x to 4.9x with a median of 4.4x.

Selected Public Companies	EV / Normalized EBITDA Multiple (2023A -2025E Avg.)	EV/ 2024E EBITDA Multiple	EV/ 2025E EBITDA Multiple
Alliance Resource Partners Inc.	4.3x	4.5x	4.4x
Alpha Metallurgical Resources, Inc.	4.2x	5.8x	4.9x
Coronado Global Resources Inc.	4.3x	4.6x	3.7x
Peabody Energy Corporation	2.9x	3.3x	3.5x
Warrior Met Coal, Inc.	4.5x	5.0x	4.6x
Median	4.3x	4.6x	4.4x

Based on the ranges observed among the selected public companies, including those identified above, PWP applied selected EV / normalized adjusted EBITDA multiple ranges to the applicable Arch and CONSOL financial metrics, including analyst consensus estimates, the Arch Forecasts and the CONSOL Forecasts, to derive implied enterprise values for Arch and CONSOL. To calculate the implied equity value of Arch from its implied enterprise value, PWP added cash and cash equivalents of $279 million, subtracted debt (including capital leases) of $135 million, subtracted pension, other post-employment benefits and black lung liabilities (on a post-tax basis) and of $157 million, and subtracted net asset reclamation obligations (on a post-tax basis) of $87 million, in each case as provided by Arch management. To calculate the implied equity value of CONSOL from its implied enterprise value, PWP added cash and cash equivalents of $299 million, subtracted debt (including capital leases) of $192 million, subtracted pension and other post-employment benefits (on a post-tax basis) of $191 million, subtracted black lung and long-term disability liabilities (on a post-tax basis) of $147 million and subtracted asset reclamation obligations (on a post-tax basis) of $210 million, in each case as provided by CONSOL management. PWP calculated implied values per share by dividing the implied equity values by the applicable diluted shares (based upon the number of issued and outstanding shares as of August 14, 2024), which was 18.466 million for Arch and 29.883 million for CONSOL, based on information provided by Arch management and CONSOL management, as applicable, and with respect to Arch, including restricted stock units, and with respect to CONSOL, including restricted stock units and performance share units. PWP applied a selected multiple range of 4.0x to 5.0x to Arch’s 2023A-2025E Average EBITDA, resulting in implied reference ranges per share of Arch common stock of $129 to $162 and $125 to $158, based the Arch Forecasts and on analyst consensus estimates, respectively. PWP applied a selected multiple range of 4.0x to 5.0x to CONSOL’s 2023A-2025E Average EBITDA, resulting in implied reference ranges per share of CONSOL common stock of $99 to $127 and $91 to $117, based the CONSOL Forecasts and on analyst consensus estimates, respectively.

The first paragraph under the heading “Opinion of Perella Weinberg Partners LP, Arch’s Financial Advisor—Summary of PWP’s Financial Analyses—Discounted Cash Flow Value Analysis” on pages 111 through 112 is amended as follows:

PWP conducted a discounted cash flow analysis for each of Arch and CONSOL based on the Forecasts to derive a range of implied enterprise values for Arch and CONSOL by:

calculating the present value as of August 20, 2024 of the estimated standalone unlevered free cash flows in the case of Arch, calculated as Adjusted EBITDA (as defined in in the section entitled “The Merger Agreement—Arch Unaudited Prospective Financial Information” beginning on page 1189 of this joint proxy) minus cash taxes, plus/minus the change in net working capital, minus capital invested in equity investments, minus capital expenditures, minus non-operating expenses, minus other operating and investing activities, plus certain legacy liability costs, minus dividends forecasted to be paid in the third quarter of 2024 and fourth quarter of 2024, minus the cash tax benefit from net operating losses and in the case of CONSOL, calculated as Adjusted EBITDA (as defined in in the section entitled “The Merger Agreement—CONSOL Unaudited Prospective Financial Information” beginning on page 115 of this joint proxy) minus stock based compensation, plus annual non-service costs related to pension, supplemental executive retirement plan (SERP), other post-employment benefits, black lung liabilities and long term disability benefits, minus cash taxes, plus/minus the change in net working capital, minus capital expenditures, minus gains attributable to asset sales, plus changes in other assets and liabilities, minus employee-related long-term liabilities, minus dividends forecasted to be paid in the third quarter of 2024 and fourth quarter of 2024, expected to be generated by Arch and CONSOL for the six months ending December 31, 2024 and the years ending December 31, 2025 through December 31, 2028, as included in the Forecasts, using discount rates ranging from, in the case of Arch, 9.5% to 10.75% and, in the case of CONSOL, 9.75% to 11.00%, and a mid-year convention for discounting; and

adding the present value as of August 20, 2024 of the terminal value of Arch and CONSOL at the end of calendar year 2028 (which terminal values were calculated to be $2,786-3,482 million for Arch and $3,696-4,620 million for CONSOL) using an implied terminal EBITDA multiple range of, in the case of Arch, 4.0x to 5.0x 2028E Adjusted EBITDA (as defined in in the section entitled “The Merger Agreement—Arch Unaudited Prospective Financial Information” beginning on page 1189 of this joint proxy) and, in the case of CONSOL, 4.0x to 5.0x 2028E Adjusted EBITDA (as defined in in the section entitled “The Merger Agreement—CONSOL Unaudited Prospective Financial Information” beginning on page 115 of this joint proxy) minus stock based compensation, plus annual non-service costs related to pension, supplemental executive retirement plan (SERP), other post-employment benefits, black lung liabilities and long term disability benefits, and discount rates ranging from, in the case of Arch, 9.5% to 10.75% and, in the case of CONSOL, 9.75% to 11.00%. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts to a specific point in time by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, capital structure, income taxes, expected returns and other appropriate factors taken into account based on the professional judgment and experience of PWP.

The third and fourth paragraphs under the heading “Opinion of Perella Weinberg Partners LP, Arch’s Financial Advisor-Summary of PWP’s Financial Analyses—Discounted Cash Flow Value Analysis” on page 112 are amended and restated as follows:

PWP used tThe discount rates as used by PWP for each of Arch and CONSOL were determined based on PWP’s analysis an estimated range of Arch’s and CONSOL’s respective weighted average cost of capital., which was derived by application of the Capital Asset Pricing Model, which takes into account certain company-specific metrics, including Arch’s and CONSOL’s respective target capital structure, the cost of long-term debt, forecasted tax rate and unlevered and levered (Barra) beta, as well as certain financial metrics for the United States financial markets generally, including market risk premium and the 20-year treasury rate (30-day average) as of August 19, 2024.

From the range of implied enterprise values, PWP derived a range of implied equity values for Arch and CONSOL. To calculate the implied equity value of Arch from its implied enterprise value, PWP added cash and cash equivalents of $279 million, subtracted debt (including capital leases) of $135 million, subtracted pension, other post-employment benefits and black lung liabilities (on a post-tax basis) of $157 million, subtracted net asset reclamation obligations (on a post-tax basis) of $87 million, and added the present value of net operating losses (using a discount rate of approximately 6.50%, which rate reflects the midpoint of Arch’s post-tax cost of debt as of August 19, 2024) of $77 million, in each case as provided by Arch management. To calculate the implied equity value of CONSOL from its implied enterprise value, PWP added cash and cash equivalents of $299 million, subtracted debt (including capital leases) of $192 million, subtracted pension and other post-employment benefits (on a post-tax basis) of $191 million, subtracted black lung and long-term disability liabilities (on a post-tax basis) of $147 million and subtracted asset reclamation obligations (on a post-tax basis) of $210 million, in each case as provided by CONSOL management. PWP calculated implied values per share by dividing the implied equity values by the applicable diluted shares (based upon the number of issued and outstanding shares as of August 14, 2024), which was 18.466 million for Arch and 29.883 million for CONSOL, based on information provided by Arch management and CONSOL management, as applicable, and with respect to Arch, including restricted stock units, and with respect to CONSOL, including restricted stock units and performance share units.

The third paragraph under the heading “Opinion of Perella Weinberg Partners LP, Arch’s Financial Advisor-Summary of PWP’s Financial Analyses-Equity Research Analysists’ Price Targets” on page 113 is amended as follows:

Based on comparisons of the high and low research analyst price targets for Arch and CONSOL, PWP derived a range of implied exchange ratios of shares of Arch common stock to shares of CONSOL common stock of 1.483x to 1.931x. PWP compared this exchange ratio range to the exchange ratio of 1.326 shares of CONSOL common stock to be received for each share of Arch common stock as provided for in the merger agreement. The five price targets for Arch observed, when discounted for a period of one year using a cost of equity of 10.50%, were $140, $145, $154, $163 and $179 per share. The two price targets for Arch observed, when discounted for a period of one year using a cost of equity of 11.00%, were $93 and $95 per share. The price targets published by equity research analysts do not necessarily reflect current market trading prices for shares of Arch common stock or CONSOL common stock and these estimates are subject to uncertainties, including the future financial performance of Arch, CONSOL and future financial market conditions.

The last paragraph on page 124 under the heading “Board of Directors and Management of the Combined Company Following the Completion of the Merger” is amended as follows:

Under the terms of the merger agreement, CONSOL has agreed to take all actions as may be necessary to cause (1) the number of directors constituting the combined company’s board as of the effective time of the merger to be eight and (2) the combined company’s board as of the effective time of the merger to be composed of (A) four directors designated by CONSOL, one of whom will be James A. Brock, and (B) four directors designated by Arch, two of whom will be Paul A. Lang and Richard A. Navarre. From and after the effective time of the merger, each person designated as a director of the combined company will serve as a director until such person’s successor has been appointed and qualified or elected or such person’s earlier death, resignation or removal in accordance with the organizational documents of the combined company. Directors of the combined company board will be selected by the membership of the current CONSOL board and Arch board based on their individual experience and skill sets, the overall skill set and composition of the resulting combined company board, and their willingness to serve on the combined company board.

The paragraph on page 133 under the heading “Mr. Brock’s Role with the Combined Company following Completion of the Merger” is amended as follows:

On August 20, 2024, Mr. Brock entered into a Waiver, Acknowledgment and Amendment, pursuant to which Mr. Brock has agreed to serve as Executive Chair of the combined company, reporting to the combined company’s board, following completion of the merger. Mr. Lang will serve as Chief Executive Officer of the combined company following the merger, reporting to Mr. Brock. Mr. Brock has further agreed that the change in his duties upon completion of the merger will not constitute “Good Reason” for purposes of and as defined in the Brock Employment Agreement. Mr. Brock will also serve on the combined company’s board as of the effective time of the merger. Other than as described in this joint proxy statement/prospectus, no changes to Mr. Brock’s compensation arrangements or the Brock Employment Agreement (described under the heading “CEO Employment Agreement” on page 58 of CONSOL’s annual proxy statement for CONSOL’s 2024 Annual Meeting of Stockholders, filed on April 1, 2024) have been agreed to or approved. Each of CONSOL and Arch has begun working with its third party advisors, including existing compensation consultants, to prepare materials regarding post-closing compensation arrangement alternatives. Following the merger, the combined company’s board and/or compensation committee will be presented with recommendations related to future executive officer compensation and will make all decisions relating to any such arrangements, including whether to grant any emergence or similar awards.
