The following table sets forth the computation of basic and diluted earnings per share ("EPS") which are calculated using the treasury stock method:


	First Quarter
(In millions, except per share amounts)	2026		2025
Numerator
Earnings attributable to Eastman, net of tax	$	107	$	182



Denominator
Weighted average shares used for basic EPS	114.2		115.2
Dilutive effect of stock options and other awards	0.8		1.3
Weighted average shares used for diluted EPS	115.0		116.5

(Calculated using whole dollars and shares)
EPS
Basic	$	0.93	$	1.58
Diluted	$	0.93	$	1.57

Shares underlying stock options of 4,051,375 and 1,716,564 for first quarter 2026 and 2025 were excluded from the calculations of diluted EPS because the grant date exercise price of these options was greater than the average market price of the Company's common stock and the effect of including them in the calculations of diluted EPS would have been antidilutive. No shares were repurchased in first quarter 2026 or 2025.
