EARNINGS PER SHARE

6 Months Ended

Jun. 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 June 30,		Six months ended June 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	146	36	345	73
Denominator:
Basic - weighted-average ordinary shares outstanding	135,866,171	140,820,828	135,633,294	141,665,123
Dilutive effect of non-vested restricted stock units and performance-based restricted stock units	4,287,582	1,423,571	4,488,781	1,508,801
Diluted - weighted-average ordinary shares, of restricted stock units and performance-based restricted stock units	140,153,753	142,244,399	140,122,075	143,173,924
Basic earnings per share	$1.07	$0.25	$2.54	$0.51
Diluted earnings per share	$1.04	$0.25	$2.46	$0.51

For the three and six months ended June 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.
