Basic earnings per share are computed based on the weighted average number of common shares outstanding. Diluted earnings per share are calculated to reflect the potential dilution that could occur if securities or other contracts were exercised or converted into common stock.

Basic and diluted earnings per common share are calculated as follows:


	Three Months Ended
	March 31,
(In millions, except per share amounts)	2025		2024
Earnings (loss) per share — basic:
Goodyear net income (loss)	$	115	$	(57	)
Weighted average shares outstanding		287		286
Earnings (loss) per common share — basic	$	0.40	$	(0.20	)

Earnings (loss) per share — diluted:
Goodyear net income (loss)	$	115	$	(57	)
Weighted average shares outstanding		287		286
Dilutive effect of stock options and other dilutive securities		2		—
Weighted average shares outstanding — diluted		289		286
Earnings (loss) per common share — diluted	$	0.40	$	(0.20	)

Weighted average shares outstanding — diluted for the three months ended March 31, 2025 and 2024 excludes approximately 3 million and 1 million equivalent shares, respectively, related to options with exercise prices greater than the average market price of our common shares (i.e., "underwater" options). Additionally, weighted average shares outstanding — diluted for the three months ended March 31, 2024 excludes the dilutive effect of approximately 2 million equivalent shares, related primarily to unvested restricted stock units and options with exercise prices less than the average market price of our common shares (i.e., "in-the-money" options), as their inclusion would have been anti-dilutive due to the Goodyear net loss.
