The following table sets forth the computation of basic and diluted net loss per share attributable to our common shareholders for the three and six months ended June 30, 2023 and 2022, respectively (in thousands, except share and per share amounts):

	Three Months Ended June 30,						Six Months Ended June 30,
	2023			2022			2023			2022
Net loss attributable to Adaptive Biotechnologies Corporation	$	(47,810	)	$	(52,046	)	$	(105,509	)	$	(114,782	)
Weighted-average shares used in computing net loss per share attributable to Adaptive Biotechnologies Corporation common shareholders, basic and diluted		144,397,693			142,363,589			143,956,867			142,032,261

Given the loss position for all periods presented, basic net loss per share attributable to our common shareholders is the same as diluted net loss per share attributable to our common shareholders, as the inclusion of all potential shares of common stock outstanding would have been anti-dilutive.

The following weighted-average common stock equivalents were excluded from the calculation of diluted net loss per share attributable to our common shareholders for the three and six months ended June 30, 2023 and 2022, respectively, as they had an anti-dilutive effect:
