Earnings (Loss) per Share [Abstract]

Note 3. Earnings (loss) per Share (EPS)

Basic earnings (loss) per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings (loss) per share are based upon the weighted average number of common shares outstanding during the period, assuming the issuance of common shares for all potentially dilutive common shares outstanding.

The following table sets forth the computation of basic and diluted earnings (loss) per share:


	Three Months Ended

(in millions of dollars, except per share data)		2026		2025

Weighted average shares outstanding		31.0		31.9
Dilutive effect of stock options and deferred restricted stock units		-		-
Weighted average shares outstanding, adjusted		31.0		31.9

Basic earnings (loss) per share attributable to Minerals Technologies Inc.	$	1.17	$	(4.51	)

Diluted earnings (loss) per share attributable to Minerals Technologies Inc.	$	1.17	$	(4.51	)

Of the options outstanding of 1,678,847 and 1,596,748 for the three-month periods ended April 5, 2026 and March 30, 2025, respectively, options to purchase 943,056 shares and 1,596,748 shares of common stock for the three-month periods ending April 5, 2026 and March 30, 2025, respectively, were not included in the computation of diluted earnings (loss) per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares. Due to our net loss for the three-month period ending March 30, 2025, all options to purchase shares were anti-dilutive and were excluded for this period.
