Summary of Significant Accounting Policies

Basis of Presentation

(a) Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information and should be read in the context of the Company’s December 31, 2023 consolidated financial statements and notes thereto for a more complete understanding of the Company’s operations, financial position and accounting policies. The Company’s December 31, 2023 consolidated financial statements were included in Antero Resources’ 2023 Annual Report on Form 10-K, which was filed with the SEC.

These unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information, and, accordingly, do not include all of the information and footnotes required by GAAP for complete consolidated financial statements. In the opinion of management, these unaudited condensed consolidated financial statements include all adjustments (consisting of normal and recurring accruals) considered necessary to present fairly the Company’s financial position as of December 31, 2023 and March 31, 2024, results of operations and cash flows for the three months ended March 31, 2023 and 2024. The Company has no items of other comprehensive income or loss; therefore, its net income or loss is equal to its comprehensive income or loss. Operating results for the three months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the full year because of the impact of fluctuations in prices received for natural gas, NGLs and oil, natural production declines, the uncertainty of exploration and development drilling results, fluctuations in the fair value of derivative instruments and other factors.

Principles of Consolidation

(b) Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Antero Resources Corporation, its wholly owned subsidiaries and its variable interest entity (“VIE”), Martica Holdings LLC, (“Martica”), for which the Company is the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in the Company’s unaudited condensed consolidated financial statements.

Cash and Cash Equivalents

(c) Cash and Cash Equivalents

The Company considers all liquid investments purchased with an initial maturity of three months or less to be cash equivalents. The carrying value of cash and cash equivalents approximates fair value due to the short-term nature of these instruments. From time to time, the Company may be in the position of a “book overdraft” in which outstanding checks exceed cash and cash equivalents. The Company classifies book overdrafts in accounts payable and revenue distributions payable within its condensed consolidated balance sheets, and classifies the change in accounts payable associated with book overdrafts as an operating activity within its unaudited condensed consolidated statements of cash flows. As of December 31, 2023, the book overdrafts included within accounts payable and revenue distributions payable were $11 million and $19 million, respectively. As of March 31, 2024, the book overdrafts included within accounts payable and revenue distributions payable were $7 million and $24 million, respectively.

Net Income Per Common Share

(d) Net Income Per Common Share

Net income per common share—basic for each period is computed by dividing net income attributable to Antero by the basic weighted average number of common shares outstanding during the period. Net income per common share—diluted for each period is computed after giving consideration to the potential dilution from (i) outstanding equity awards using the treasury stock method and (ii) shares of common stock issuable upon conversion of the 2026 Convertible Notes (as defined below in Note 7—Long-Term Debt) using the if-converted method. The Company includes restricted stock unit (“RSU”)

awards, performance share unit (“PSU”) awards and stock options in the calculation of diluted weighted average common shares outstanding based on the number of common shares that would be issuable if the end of the period was also the end of the performance period required for the vesting of the awards. During periods in which the Company incurs a net loss, diluted weighted average common shares outstanding are equal to basic weighted average common shares outstanding because the effects of all equity awards and the 2026 Convertible Notes are anti-dilutive.

The following is a reconciliation of the Company’s income attributable to common stockholders for basic and diluted net income per common share (in thousands):

	Three Months Ended March 31,
	2023		2024
Net income attributable to Antero Resources Corporation—common shareholders	$	213,431		36,345
Add: Interest expense for 2026 Convertible Notes		616		256
Less: Tax-effect of interest expense for 2026 Convertible Notes		(132)		(56)
Net income attributable to Antero Resources Corporation—common shareholders and assumed conversions	$	213,915		36,545
Net income per common share—basic	$	0.72		0.12
Net income per common share—diluted	$	0.69		0.12
Weighted average common shares outstanding—basic		296,763		304,943
Weighted average common shares outstanding—diluted		311,846		312,503

The following is a reconciliation of the Company’s basic weighted average common shares outstanding to diluted weighted average common shares outstanding during the periods presented (in thousands):

	Three Months Ended March 31,
	2023	2024
Basic weighted average number of common shares outstanding	296,763	304,943
Add: Dilutive effect of RSUs	2,150	1,307
Add: Dilutive effect of PSUs	1,060	1,389
Add: Dilutive effect of 2026 Convertible Notes	11,873	4,864
Diluted weighted average number of common shares outstanding	311,846	312,503
Weighted average number of outstanding securities excluded from calculation of diluted net income per common share (1):
RSUs	969	371
PSUs	414	—
Stock options	324	259

(1) The potential dilutive effects of these awards were excluded from the computation of net income per common share—diluted because the inclusion of these awards would have been anti-dilutive.
