NET INCOME (LOSS) PER SHARE

Basic net income (loss) per common share attributable to Altice USA stockholders is computed by dividing net income (loss) attributable to Altice USA stockholders by the weighted average number of common shares outstanding during the period. Diluted income per common share attributable to Altice USA stockholders reflects the dilutive effects of stock options and restricted stock. For such awards that are performance based, the diluted effect is reflected upon the achievement of the performance criteria. Diluted net loss per common share attributable to Altice USA stockholders excludes the effects of common stock equivalents as they are anti-dilutive.
