Earnings Per Share [Abstract]

Net Loss Per Share Attributable to Common Shareholders

9. Net Loss Per Share Attributable to Common Shareholders

IronNet computes basic earnings per share (EPS) by dividing income available to common shareholders by the weighted average number of common shares outstanding for the reporting period. Diluted EPS reflects the effect of potential shares that would be issued if stock option awards, restricted stock units, and preferred stock were converted into common stock, to the extent dilutive. Other than voting rights, the Class B common stock has the same rights as the Class A common stock and therefore both are treated as the same class of stock for the purposes of the earnings per share calculation.

The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders:

	Three months ended July 31,						Six months ended July 31,
	2021			2020			2021			2020
Numerator: Net loss	$	(17,167	)	$	(14,285	)	$	(32,667	)	$	(30,702	)
Denominator: Weighted-average shares in computing net loss per share attributable to common stockholders		54,838			53,768			54,694			53,772
Net loss attributable to common shareholders—basic and diluted	$	(0.31	)	$	(0.27	)	$	(0.60	)	$	(0.57	)

Since the Company was in a net loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been antidilutive. The potential shares of common stock that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive are as follows as of July 31:​​​​​​​

	As of July 31, 2021		As of July 31, 2020
Shares of common stock issuable from stock options		1,840		4,139
RSUs subject to future vesting		21,589		19,669
Shares of common stock issuable upon conversion from preferred shares		28,046		25,882
Potential common shares excluded from diluted net loss per share		51,475		49,690
