PITTSBURGH, February 23, 2024 – CNX Resources Corporation (NYSE: CNX) (“CNX,” “we,” or “our”) today announced the closing of its private placement of $400 million aggregate principal amount of its 7.250% senior notes due 2032 (the “Notes”). The Notes were offered under an indenture, dated February 23, 2024 (the “Indenture”), among CNX, the subsidiary guarantors party thereto and UMB Bank, N.A., as trustee. The Notes are guaranteed by all of CNX’s wholly-owned domestic restricted subsidiaries that guarantee its revolving credit facility.

CNX intends to use the net proceeds of the sale of the Notes to (i) purchase any and all of its outstanding 7.250% senior notes due 2027 (the “2027 Notes”) pursuant to the tender offer that commenced concurrently with the offering of the Notes (the “Tender Offer”), (ii) to the extent any 2027 Notes remain outstanding after the Tender Offer, fund the redemption of all 2027 Notes not purchased in the Tender Offer (the “Redemption”) and (iii) repay borrowings under its revolving credit facility, with any remaining proceeds used for general corporate purposes.

The Notes have not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and the rules promulgated thereunder and applicable state securities laws. The Notes have been and will be offered only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and non-U.S. persons in transactions outside the United States in reliance on Regulation S under the Securities Act.

Various statements in this release, including those that express a belief, expectation or intention, may be considered forward-looking statements (as defined in Section 21E of the Securities Exchange Act of 1934, as amended) that involve risks and uncertainties that could cause actual results to differ materially from projected results. Accordingly, investors should not place undue reliance on forward-looking statements as a prediction of actual results. When we use the words “believe,” “intend,” “expect,” “may,” “should,” “anticipate,” “could,” “estimate,” “plan,” “predict,” “project,” “will” or their negatives, or other similar expressions, the statements which include those words are usually forward-looking statements.

therefrom, the Tender Offer and the Redemption, speak only as of the date of this press release; we disclaim any obligation to update these statements unless required by securities laws and we caution you not to rely on them unduly. We have based these forward-looking statements on our current expectations and assumptions about future events. While our management considers these expectations and assumptions to be reasonable, they are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control.
