INCOME TAXES INCOME TAXES:
The effective tax rates for the three and six months ended June 30, 2025 were 26.1% and 24.9%, respectively. The effective tax rates for the three and six months ended June 30, 2024 were (19.8)% and (27.9)%, respectively. The effective tax rate for the three and six months ended June 30, 2025 and 2024 differs from the U.S. federal statutory rate of 21% primarily due to the impact of equity compensation, federal tax credits, and state taxes.

The total amount of uncertain tax positions at June 30, 2025 and December 31, 2024 were $130,123 and $113,227, respectively. If these uncertain tax positions were recognized, approximately $130,123 and $113,227 would affect CNX's effective tax rate at June 30, 2025 and December 31, 2024, respectively. In 2025, CNX recognized an increase in unrecognized tax benefits of $16,896 for tax benefits resulting from tax positions anticipated to be claimed on our 2025 federal income tax return for additional federal tax credits.

CNX recognizes accrued interest and penalties related to uncertain tax positions in interest expense and income tax expense, respectively. As of June 30, 2025 and December 31, 2024, CNX had no accrued liabilities for interest and penalties related to uncertain tax positions.
CNX and its subsidiaries file federal income tax returns with the United States and tax returns within various states. With few exceptions, the Company is no longer subject to United States federal, state, local, or non-U.S. income tax examinations by tax authorities for the years before 2021.
