Basic loss per share of common stock is computed by dividing the net loss income applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period.

For the three and nine months ended September 30, 2025, diluted loss per share is computed on the same basis as there were no convertible securities outstanding. For the three and nine months ended September 30, 2024, diluted loss per share is computed by dividing the net loss applicable to common stockholders by the weighted average number of shares outstanding assuming the conversion of the Series C Preferred into an aggregate of 16,500,000 shares of common stock. Based on the applicable accounting guidance, Harbor was required to apply the “if-converted” method to the Series C Preferred to determine the weighted average number of shares outstanding for purposes of calculating the net loss per share of common stock. However, conversion was not assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive.

In January 2020, Harbor issued 4,000,000 shares of the Series C Preferred. The rights, preferences, privileges, qualifications, restrictions and limitations relating to the Series C Preferred are set forth in the Certificate of Designations, Preferences and Rights of Series C Convertible Redeemable Preferred Stock (“Certificate of Designations”), which Harbor filed with the Secretary of State of the State of Delaware.

Harbor accounted for its Series C Preferred in accordance with the guidance in ASC 480, Distinguishing Liabilities from Equity. Based on the applicable accounting guidance, preferred stock that is conditionally redeemable is classified as temporary or “mezzanine” equity. Accordingly, the Series C Preferred, which was subject to conditional redemption, was presented at redemption value as mezzanine equity outside of the stockholders’ equity section of the condensed consolidated balance sheets.

Each share of Series C Preferred was initially convertible at the election of the holders, at any time after issuance, into that number of shares of common stock determined by dividing the then applicable Series C Liquidation Amount (as defined below) by $0.80, subject to certain adjustments set forth in the Certificate of Designations (“Conversion Price”). The Conversion Price was subsequently adjusted to be $0.15091.

Based on the applicable accounting guidance, Harbor was required to apply the “if-converted” method to the Series C Preferred to determine the weighted average number of shares outstanding for purposes of calculating the net income (loss) per share of common stock.

On June 28, 2024, 754,550 shares of Series C Preferred were converted into 16,500,000 shares of Harbor's common stock, and all of the 3,245,450 Conversion Cap Excess Shares were redeemed for $10,710. After giving effect to such conversion and redemption, no shares of Series C Preferred were outstanding as of September 30, 2025 and September 30, 2024, and such shares did not have any impact on the calculation of diluted earnings per share as of such dates. In addition, following the conversion no dividends were declared or paid on the Series C Preferred.

As all of the Series C Preferred was converted or redeemed as of June 28, 2024, mezzanine equity is no longer presented on the consolidated balance sheets after that date.
