Item 2.01. Completion of Acquisition or Disposition of Assets.

On February 24, 2021, Sunesis Pharmaceuticals, Inc. (the “Company”) completed its business combination with Viracta Therapeutics, Inc. (“Viracta”), in accordance with the terms of the Agreement and Plan of Merger and Reorganization, dated November 29, 2020, by and among the Company, Sol Merger Sub, Inc. (“Merger Sub”) and Viracta (the “Merger Agreement”), pursuant to which Merger Sub merged with and into Viracta, with Viracta surviving as a wholly owned subsidiary of the Company (the “Merger”).

Also, on February 24, 2021, in connection with and immediately prior to the effective time of the Merger (the “Effective Time”), the Company effected a reverse stock split of the Company’s common stock, par value $0.0001 per share (“Common Stock”), at a ratio of 3.5:1 (the “Reverse Stock Split”), and changed its name from “Sunesis Pharmaceuticals, Inc.” to “Viracta Therapeutics, Inc.” (the “Name Change”). Following the completion of the Merger, the business conducted by the Company became primarily the business conducted by Viracta, a clinical-stage, biomarker-directed precision oncology company focused on advancing new medicines for the treatment of virus-associated malignancies.

Under the terms of the Merger Agreement, the Company issued shares of its Common Stock to Viracta’s stockholders, at an exchange ratio of 0.3917 shares of Common Stock (prior to taking into account the Reverse Stock Split), in exchange for each share of Viracta’s common stock outstanding as of the Effective Time (including the shares of common stock issuable upon conversion of all shares of preferred stock prior to the Effective Time). The Company also assumed all of the stock options issued and outstanding under the Viracta 2016 Equity Incentive Plan, as amended, (the “Viracta Plan”) and issued and outstanding warrants of Viracta, with such stock options and warrants henceforth representing the right to purchase a number of shares of Common Stock equal to 0.3917 multiplied by the number of shares of Viracta’s common stock previously represented by such stock options and warrants, as applicable, prior to taking into account the Reverse Stock Split.

Immediately following the Effective Time, there were approximately 37.0 million shares of Common Stock outstanding (post Reverse Stock Split). Immediately following the Effective Time, the former Viracta stockholders owned approximately 86.05% of the outstanding shares of Common Stock, and the Company’s stockholders immediately prior to the Merger, whose shares of Common Stock remain outstanding after the Merger, owned approximately 13.95% of the outstanding shares of Common Stock.

The issuance of the shares of Common Stock to the former stockholders of Viracta was registered with the U.S. Securities and Exchange Commission (the “SEC”) on a Registration Statement on Form S-4 (Reg. No. 333-251567) (the “Registration Statement”). The issuance of the shares of Common Stock to holders of stock options issued, or to be issued, under the Viracta 2016 Equity Incentive Plan will be registered with the SEC on a Registration Statement on Form S-8.

The Common Stock, which was previously listed on The Nasdaq Stock Market LLC (“Nasdaq”) and traded through the close of business on February 24, 2021, under the ticker symbol “SNSS,” will commence trading on Nasdaq under the ticker symbol “VIRX” on February 25, 2021. The shares previously traded on The Nasdaq Capital Market but will begin trading on The Nasdaq Global Select Market as of February 25, 2021. The Common Stock has a new CUSIP number, 92765F108.

The foregoing description of the Merger Agreement, the Reverse Stock Split and the Name Change do not purport to be complete and are qualified in its entirety by reference to the full text of the Merger Agreement that was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the SEC on November 30, 2020 and the certificates of amendment to the amended and restated certificate of incorporation to effect the Reverse Stock Split and the Name Change, copies of which are attached as Exhibit 3.1 and Exhibit 3.2 hereto, respectively, and are incorporated herein by reference.

Item 3.03. Material Modification to Rights of Security Holders

To the extent required by Item 3.03 of Form 8-K, the information contained in Item 2.01 of this Current Report on Form 8-K is incorporated by reference herein.

As previously disclosed, at a special meeting of the Company’s stockholders held on February 22, 2021 (the “Special Meeting”), the Company’s stockholders approved the Reverse Stock Split.

On February 24, 2021, in connection with the Merger and effective at 4:02 p.m. Eastern Time, immediately prior to the Effective Time, the Company amended its amended and restated certificate of incorporation to effect the Reverse Stock Split and the Name Change. As of the opening of trading on Nasdaq on February 25, 2021, the Common Stock will begin to trade on a Reverse Stock Split-adjusted basis.

As a result of the Reverse Stock Split, the number of issued and outstanding shares of Common Stock immediately prior to the Reverse Stock Split was reduced into a smaller number of shares, such that every 3.5 shares of Common Stock held by a stockholder immediately prior to the Reverse Stock Split were combined and reclassified into one share of Common Stock after the Reverse Stock Split. Immediately following the Reverse Stock Split and the Merger, there were approximately 37.0 million shares of Common Stock outstanding.

No fractional shares were issued in connection with the Reverse Stock Split. In accordance with the certificate of amendment to the amended and restated certificate of incorporation of the Company, any fractional shares resulting from the Reverse Stock Split were rounded down to the nearest whole number and each stockholder who would otherwise be entitled to a fraction of a share of Common Stock upon the consummation of the Reverse Stock Split (after aggregating all fractions of a share to which such stockholder would otherwise be entitled) shall, in lieu thereof, be entitled to receive a cash payment in an amount equal to the fraction to which the stockholder would otherwise be entitled multiplied by the closing sales price of a share of Common Stock (as adjusted to give effect to the Reverse Stock Split) as reported on Nasdaq on February 24, 2021, the date the certificate of amendment was filed with the Secretary of State of the State of Delaware.

In accordance with the certificate of amendment to the amended and restated certificate of incorporation of the Company, no corresponding adjustment was made with respect to the Company’s authorized Common Stock or Preferred Stock. The Reverse Stock Split has no effect on the par value of Common Stock or Preferred Stock of the Company. Immediately after the Reverse Stock Split, prior to giving effect to the Merger, each stockholder’s percentage ownership interest in the Company and proportional voting power remained unchanged, other than as a result of the rounding to eliminate fractional shares, as described in the preceding paragraph. The rights and privileges of the holders of shares of Common Stock will be unaffected by the Reverse Stock Split.

The foregoing descriptions of the certificate of amendment to the amended and restated certificate of incorporation of the Company to effect the Reverse Stock Split are not complete and are subject to and qualified in their entirety by reference to such certificate of amendment to the amended and restated certificate of incorporation, a copy of which is attached as Exhibit 3.1 hereto and is incorporated herein by reference.

Item 5.01. Changes in Control of Registrant.

Pursuant to the terms of the Merger Agreement, one of such directors was designated by the Company pre-Merger and six of such directors were designated by Viracta.
