5.Net Loss per Share

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period. An aggregate of 12,197,554 shares of common stock issuable upon the exercise of the PHC Exchange Warrant (as defined below), the Purchase Warrant (as defined below) held by PHC Holdings Corporation, the parent company of Ascensia (“PHC”) and the May 2026 Pre-Funded Warrants (as defined below) are included in the number of outstanding shares used for the computation of basic net loss per share for the three and six months ended June 30, 2026 and 2025. Since the shares are issuable for little or no consideration, sometimes referred to as “penny warrants”, they are considered outstanding in the context of earnings per share, as discussed in ASC 260-10-45-13.

​

Diluted net loss per share is computed using the weighted average number of common shares outstanding during the period and, when dilutive, potential common share equivalents. Potentially dilutive common shares consist of

shares issuable from restricted stock units (“RSUs”), stock options, warrants and the Company’s convertible notes. Potentially dilutive common shares issuable upon vesting of restricted stock units, exercise of stock options and exercise of warrants are determined using the average share price for each period under the treasury stock method. Potentially dilutive common shares issuable upon conversion of the Company’s convertible notes are determined using the if-converted method. The if-converted method assumes conversion of convertible securities at the beginning of the reporting period. Interest expense, dividends, and the changes in fair value measurement recognized during the period are added back to the numerator. The denominator includes the common shares issuable upon conversion of convertible securities.

​

In periods of net loss, all potentially dilutive common shares are excluded from the computation of the diluted net loss per share for those periods, as the effect would be anti-dilutive.
