Item 2. Unregistered Sales of Equity Securities, Use of Proceeds, and Issuer Purchases of Equity Securities

Pyramid Agreement

In January 2024, we acquired Pyramid Biosciences, Inc. ("Pyramid"), pursuant to an Agreement and Plan of Merger, dated January 7, 2024 (the "Pyramid Agreement"). In consideration for the Pyramid acquisition we made an upfront payment of 255,794 of our common shares. We also agreed to make additional success-based payments upon the achievement of certain regulatory milestones, which we may elect to pay in cash or our common shares. In January 2024, a payment became due to Pyramid related to achievement of a developmental milestone under the Pyramid Agreement, which we elected to pay in 98,129 of our common shares. The shares related to both of these payments were not registered under the Securities Act upon issuance, and a portion of the shares were subsequently registered under our Registration Statement on Form S-3.

Pyramid represented that, among other things, it is an institutional accredited investor as defined in Rule 501(a) of Regulation D of the Securities Act. The foregoing shares shall be issued in reliance on the private offering exemption provided by Section 4(a)(2) of the Securities Act. See Note 10, "License, Acquisitions and Other Agreements," to the Condensed Consolidated Financial Statements appearing elsewhere in this report for additional details on this transaction.

On May 3, 2024, we entered into an amendment (the “Amendment”) to our existing Membership Interest Purchase Agreement, dated as of February 24, 2022, with Knopp Biosciences LLC (“Knopp”) in order to make certain changes to the royalty payment obligations and success-based payments. See Item 5, “Other

Information” for additional information related to the Amendment.

In connection with the Amendment, we agreed to issue to Knopp 1,872,874 of our common shares, valued at approximately $75 million, through a private placement within 60 days of the date of execution of the Amendment (the “2024 Additional Consideration”). We also agreed to issue additional shares of our common shares, valued at approximately $75 million, within 60 days of the first anniversary of execution of the Amendment (the “2025 Additional Consideration”). In addition, we issued to Knopp a warrant (the "Warrant") to purchase 294,195 of our common shares at a purchase price per share of $67.98, subject to certain specified development milestones and achieving a specified market capitalization.

The foregoing issuance and sale of our common shares in connection with the execution of the Amendment and the Warrant have not been registered under the Securities Act of 1933 (the “Securities Act”) or any state securities laws. We have relied on the exemption from the registration requirements of the Securities Act under Section 4(a)(2) thereof, for a transaction by an issuer not involving any public offering.
