On June 2, 2020, the Board determined to set the Reverse Stock Split ratio at 1-for-5 (the “Split Ratio”). The Certificate of Amendment was filed with the Secretary of State of the State of Delaware on June 11, 2020, upon which the Reverse Stock Split became effective immediately (the “Effective Time”). At the Effective Time, every five shares of Common Stock issued and outstanding automatically combined into one validly issued, fully paid and non-assessable share of Common Stock. No fractional shares will be issued as a result of the Reverse Stock Split. Any stockholder that would otherwise hold a fractional share as a result of the Reverse Stock Split will be entitled to receive, upon surrender to the exchange agent of the certificate(s) representing its pre-split shares or upon conversion of its shares held in book-entry form, a cash payment equal to the fraction to which the stockholder would otherwise be entitled, multiplied by the closing trading price of the Common Stock on The Nasdaq Stock Market (“Nasdaq”) on June 10, 2020 (as adjusted to give effect to the Reverse Stock Split). The $0.0001 par value per share of Common Stock and other terms of the Common Stock are not affected by the Reverse Stock Split. The Reverse Stock Split will reduce the number of shares of Common Stock outstanding from approximately 15.9 million shares to approximately 3.2 million shares, subject to adjustment for the payment of cash in lieu of fractional shares. The number of authorized shares of Common Stock under the Certificate of Incorporation will remain unchanged at 50,000,000 shares.

On June 2, 2020, the Board determined to set the Reverse Stock Split ratio at 1-for-5 (the “Split Ratio”). The Certificate of Amendment was filed with the Secretary of State of the State of Delaware on June 11, 2020, upon which the Reverse Stock Split became effective immediately (the “Effective Time”). At the Effective Time, every five shares of Common Stock issued and outstanding automatically combined into one validly issued, fully paid and non-assessable share of Common Stock. No fractional shares will be issued as a result of the Reverse Stock Split. Any stockholder that would otherwise hold a fractional share as a result of the Reverse Stock Split will be entitled to receive, upon surrender to the exchange agent of the certificate(s) representing its pre-split shares or upon conversion of its shares held in book-entry form, a cash payment equal to the fraction to which the stockholder would otherwise be entitled, multiplied by the closing trading price of the Common Stock on The Nasdaq Stock Market (“Nasdaq”) on June 10, 2020 (as adjusted to give effect to the Reverse Stock Split). The $0.0001 par value per share of Common Stock and other terms of the Common Stock are not affected by the Reverse Stock Split. The Reverse Stock Split will reduce the number of shares of Common Stock outstanding from approximately 15.9 million shares to approximately 3.2 million shares, subject to adjustment for the payment of cash in lieu of fractional shares. The number of authorized shares of Common Stock under the Certificate of Incorporation will remain unchanged at 50,000,000 shares.
