EARNINGS PER SHARE

9 Months Ended

Sep. 30, 2026

NOTE 7 - EARNINGS PER SHARE

Basic earnings per share are computed using the weighted-average number of ordinary shares outstanding during the

period. Diluted earnings per share are computed using the weighted-average number of ordinary shares and ordinary share

equivalents outstanding during the period. Ordinary share equivalents represent the dilutive effect of outstanding equity-based

awards.

The reconciliation of the numerator and denominator of basic and diluted earnings per share was as follows:


	Three months ended September 30,		Nine months ended September 30,
(in millions of U.S. dollars except share and per share amounts )	2026	2025	2026	2025
Numerator:
Net income attributable to equity holders of Constellium SE	117	88	462	161
Denominator:
Basic - weighted-average ordinary shares outstanding	134,874,759	138,668,972	135,377,676	140,655,433
Dilutive effect of non-vested restricted stock units and performance-based restricted stock units	4,112,443	1,855,669	4,363,335	1,624,424
Diluted - weighted-average ordinary shares, of restricted stock units and performance-based restricted stock units	138,987,202	140,524,641	139,741,011	142,279,857
Basic earnings per share	$0.87	$0.63	$3.41	$1.14
Diluted earnings per share	$0.84	$0.62	$3.31	$1.13

For the three and nine months ended September 30, 2026, and 2025, no ordinary shares assuming exercise of equity-

based awards were excluded from the computation of diluted earnings per share because the effect of their exercise would be

anti-dilutive.

On September 17, 2026, our Board of Directors approved the cancellation of 6 million treasury shares acquired through

our share repurchase program, pursuant to the authority granted by our shareholders at the 2026 Annual General Meeting, and

the restatement of our Articles of Association to reflect the reduced share capital. The retirement of treasury shares reduced the

number of issued ordinary shares of the Company.
