On June 3, 2025, the Company sold its ViewSpot product for total consideration of $1.3 million, of which $1.0 million was paid on the closing date, with the remaining amounts to be paid in two installments, the first of which was collected on July 1, 2025, and the final balance was collected on October 1, 2025.
On April 3, 2024, the Company filed a certificate of amendment to its Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a one-for-eight (1:8) reverse stock split of the shares of the Company's common stock, par value $0.001 per share (the "Common Stock"), with an effective time of 11:59 p.m., Eastern Time on April 10, 2024 (the "Reverse Stock Split"). At the effective time, every eight shares of Common Stock, whether issued and outstanding or held by the Company as treasury stock were automatically combined and converted (without any further act) into one share of fully paid and nonassessable Common Stock, with any fractional shares resulting from the Reverse Stock Split rounded up to the nearest whole share. At the effective time, the number of shares of Common Stock then outstanding was reduced from approximately 76.8 million shares to approximately 9.6 million shares due to the Reverse Stock Split. The Reverse Stock Split did not change the Company's authorized shares of Common Stock from 100,000,000 shares or the par value of the Common Stock. Proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise of stock options and the settlement of restricted stock awards and the number of shares authorized and reserved for issuance pursuant to the Company's equity incentive plans (see Note 9). Additionally, there were adjustments to the per share exercise price and the number of shares issuable upon exercise of warrants (see Note 5). All share and per share amounts for Common Stock (including share amounts underlying convertible securities and the applicable exercise prices of such convertible securities) in these consolidated financial statements and notes thereto have been retroactively adjusted for all periods presented to give effect to the Reverse Stock Split, including reclassifying an amount equal to the reduction in the number of shares of Common Stock at par value to additional paid-in capital.
