On October 23, 2020, Plus Therapeutics, Inc. (the “Company”) entered into an Equity Distribution Agreement (the “Distribution Agreement”) with Canaccord Genuity LLC (the “Agent”), pursuant to which the Company may issue and sell, from time to time, shares of its common stock having an aggregate offering price of up to $10,000,000 (the “Shares”), depending on market demand, with the Agent acting as an agent for sales. Sales of the Shares may be made by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act of 1933, as amended (the “Securities Act”), including, without limitation, sales made directly on or through the NASDAQ Capital Market. The Agent will use its commercially reasonable efforts to sell the Shares requested by the Company to be sold on its behalf, consistent with the Agent’s normal trading and sales practices, under the terms and subject to the conditions set forth in the Distribution Agreement. The Company has no obligation to sell any of the Shares. The Company may instruct the Agent not to sell the Shares if the sales cannot be effected at or above the price designated by the Company from time to time and the Company may at any time suspend sales pursuant to the Distribution Agreement.

The Company will pay the Agent a commission of up to 3.0% of the gross proceeds from the sale of Shares by the Agent under the Distribution Agreement. The Company has also agreed to reimburse the Agent for its reasonable documented out-of-pocket expenses, including fees and disbursements of its counsel, in the amount of $50,000. In addition, the Company has agreed to provide customary indemnification rights to the Agent.

The Offering will terminate upon the earlier of (1) the issuance and sale of all shares of the Company’s common stock subject to the Distribution Agreement, or (2) the termination of the Distribution Agreement as permitted therein, including by either party at any time without liability of any party.

Any sales of Shares under the Distribution Agreement will be made pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-249410), including the related prospectus, filed with the Securities and Exchange Commission (the “SEC”) on October 9, 2020 and declared effective on October 19, 2020, as supplemented by the prospectus supplement dated October 23, 2020, and any applicable additional prospectus supplements related to the Offering that form a part of the Registration Statement. The aggregate market value of Shares eligible for sale in the Offering and under the Distribution Agreement will be subject to the limitations of General Instruction I.B.6 of Form S-3, to the extent required under such instruction. The prospectus supplement filed with the SEC on October 23, 2020 is only offering Shares having an aggregate offering price of $4,960,000 million. The Company will be required to file another prospectus supplement in the event it determines to offer more than $4,960,000 million of Shares in accordance with the terms of the Distribution Agreement, to the extent then permitted under General Instruction I.B.6 of Form S-3. The Company intends to use the net proceeds from this offering for general corporate purposes and for working capital.

The foregoing description of the Distribution Agreement does not purport to be complete and is qualified in its entirety by reference to the Distribution Agreement, which is filed as Exhibit 1.1 to this report and is incorporated herein by reference. A copy of the legal opinion of Pillsbury Winthrop Shaw Pittman LLP regarding the legality of the issuance and sale of the Shares is filed as Exhibit 5.1 to this report and is incorporated by reference herein.

This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy any Shares, nor shall there be any offer, solicitation or sale of any Shares, in any jurisdiction in which it is unlawful to make the offer, solicitation or sale.
