Weighted average number of common shares outstanding – basic and diluted | ​ |  | 41,444,979 | ​ |  | 39,122,662 | ​ |  | 41,357,423 | ​ |  | 33,830,083

​ Included within weighted average common shares outstanding for the three and six months ended June 30, 2025 and 2024 are 5,450, and 2,945,175, respectively, common shares issuable upon the exercise of certain warrants, which are exercisable at any time for nominal consideration, and as such, the shares are considered outstanding for the purpose of calculating basic and diluted net loss per share attributable to common stockholders. All warrants exercisable for common stock participate on a one-for-one basis and shares and warrants exercisable for Series X Preferred Stock issued participate on an as converted basis with common stock in the distribution of dividends, if and when declared by the board of directors, on the Company’s common stock. For purposes of computing EPS, these securities are considered to participate with common stock in earnings of the Company. Therefore, the Company calculates basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. No income was allocated to the warrants and Series X Preferred Stock for the three and six months ended June 30, 2025 and 2024, as results of operations were a loss for the period. The Company’s potentially dilutive securities include RSUs, stock options and warrants. These securities were excluded from the computations of diluted net loss per share for the three and six months ended June 30, 2025 and 2024, as the effect would be to reduce the net loss per share. The following table includes the potential shares of common stock, presented based on amounts outstanding at each period end, that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect: ​
