On April 26, 2022, InVivo Therapeutics Holdings Corp. (the “Company”) effected a reverse stock split of the Company’s common stock, par value $0.00001 per share (the “Common Stock”), at a ratio of 1-for-25 (the “Reverse Split”). As a result of the Reverse Split, every 25 shares of the issued and outstanding Common Stock were automatically converted into one newly issued and outstanding share of Common Stock, without any change in the par value per share. Any fractional shares resulting from the Reverse Split have been rounded up to the nearest whole share. In connection with the Reverse Split, the Company correspondingly reduced the number of shares of authorized shares of Common Stock from 50,000,000 to 2,000,000. All outstanding stock options and warrants will be adjusted as a result of the Reverse Split, as required by the terms of such stock options and warrants.

As previously disclosed, the Board of Directors of the Company approved the Reverse Split on April 14, 2022. On April 25, 2022, the Company filed a Certificate of Change to effect the Reverse Split pursuant to Nevada Revised Statutes Sections 78.207 and 78.209 with the Secretary of State of the State of Nevada. Under Nevada law, the Company’s Articles of Incorporation were deemed amended at the effective time of the Reverse Split, 5:00 p.m. Eastern Time on April 26, 2022.

The information set forth in Item 3.03 of this Current Report on Form 8-K is incorporated by reference into this Item 5.03.  A copy of the Certificate of Change is filed as Exhibit 3.1 to this Current Report on Form 8-K.
