[1] Potentially dilutive securities consist of unvested restricted stock awards, warrants and convertible preferred stock. Because the Company is reporting a net loss attributable to common shareholders for the three months ended March 31, 2022, all potentially dilutive securities outstanding were excluded from the calculation of diluted loss per share since their inclusion would have been anti-dilutive.
