Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On October 12, 2022, our stockholders approved a proposal at a special meeting of stockholders (the “Special Meeting”) further amending our Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), to effect a reverse stock split of our common stock, par value $0.001 per share (“Common Stock”), at a ratio between one-for-five (1:5) and one-for-twenty (1:20), without reducing the authorized number of shares of Common Stock. On November 15, 2022, our Reverse Split Committee of our Board of Directors approved a final split ratio of one-for-twenty (1:20). Following such approval, we filed an amendment to the Certificate of Incorporation (the “Amendment”) with the Secretary of State of the State of Delaware to effect the reverse stock split, with an effective time of 11:59 p.m., Eastern Time on November 15, 2022.

No fractional shares will be issued in connection with the reverse stock split. Each fractional share of Common Stock will either be (i) rounded up to the nearest whole share of Common Stock, if such shares of Common Stock are held directly; or (ii) rounded down to the nearest whole share of Common Stock, if such shares are subject to an award granted under our 2018 Equity Incentive Plan, in order to comply with the requirements of Sections 409A and 424 of the Internal Revenue Code of 1986.

The new CUSIP number for the Common Stock following the reverse stock split is 81720R 406.

The description of the Amendment set forth above does not purport to be complete and is qualified in its entirety by the full text of the Amendment, a copy of which is attached hereto as Exhibit 3.1(a) and is incorporated herein by reference.

Item 7.01. Regulation FD Disclosure.

On November 15, 2022, we issued a press release announcing the reverse stock split. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

In accordance with General Instruction B.2 of Form 8-K, the information in this Current Report on Form 8-K, including Exhibit 99.1, which is incorporated into this Item 7.01, is being furnished pursuant to Item 7.01 and shall not be deemed “filed” for the purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Exchange Act of 1934, as amended, or the Securities Act of 1933, as amended, except as shall be expressly set forth by reference in such a filing.
