Item 4. Purpose of Transaction

On November 13, 2023 (i) OPI VII, OPI VIII, OAP IV, Genesis and OPM (“OrbiMed”) and (ii) Foresite Capital Fund IV, L.P. (“FCF IV”), Foresite Capital Fund V, L.P. (“FCF V”) and Foresite Capital Opportunity Fund V, L.P. (“FCOF V”) (collectively, “Foresite” and together with OrbiMed, the “Investors”) submitted to the board of directors of the Issuer (the “Board”) a non-binding expression of interest letter (the “Letter”) setting forth an intent to explore and evaluate a potential acquisition of all of the outstanding Shares that are not owned by the Investors or their affiliates in a going-private transaction. A copy of the Letter is filed as Exhibit 1 to this Amendment No. 5, and the information set forth in the Letter is incorporated by reference herein.

The Letter may result in one or more of the transactions, events or actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, including, without limitation, an acquisition of additional securities of the Issuer, an extraordinary corporate transaction (such as a merger) involving the Issuer, delisting of the Shares from the Nasdaq Global Select Market and other material changes in the Issuer’s business or corporate structure.

The Letter stated that any transaction, once structured and agreed upon, would be conditioned upon, among other things, the (x) approval of the transaction by a properly constituted special committee composed of independent and disinterested directors of the Issuer appointed by the Board, with assistance from legal and financial advisors and (y) approval of the stockholders holding at least a majority of all the issued and outstanding Shares not held by the Investors or their affiliates.

The Letter is non-binding in nature and does not obligate in any way the Investors or the Issuer to negotiate or enter into defin itive documentation with respect to a transaction or otherwise complete a transaction. The Letter states that the Investors are only interested in acquiring the outstanding Shares that they do not already own, and are not interested in selling their Shares to another party or in participating in an alternative change of control transaction involving the Company. For the avoidance of doubt, the Investors would consider any transaction that maximizes value for, and is in the best interests of, the Company’s stockholders.

The foregoing description of the Letter does not purport to be complete and is qualified in its entirety by reference to the full text of the Letter. Neither the Letter nor this Statement is meant to be, nor should be construed as, an offer to buy or the solicitation of an offer to sell any of the Issuer’s securities.

The Reporting Persons from time to time intend to review their investment in the Issuer on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s Shares in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time. If the Reporting Persons believe that further investment in the Issuer is attractive, whether because of the market price of Shares or otherwise, they may acquire Shares or other securities of the Issuer either in the open market or in privately negotiated transactions. Similarly, depending on market and other factors, the Reporting Persons may determine to dispose of some or all of the Shares currently owned by the Reporting Persons or otherwise acquired by the Reporting Persons either in the open market or in privately negotiated transactions.

Carl Gordon (“Gordon”), a member of OrbiMed Advisors, is a member of the Board of Directors of the Issuer and, accordingly, OrbiMed Advisors, GP VII, and GP VIII may have the ability to affect and influence control of the Issuer. From time to time, Gordon may receive stock options or other awards of equity-based compensation pursuant to the Issuer’s compensation arrangements for non-employee directors. Pursuant to an agreement with OrbiMed Advisors, GP VII, and GP VIII, Gordon is obligated to transfer any securities issued under any such stock options or other awards, or the economic benefit thereof, to OrbiMed Advisors, GP VII, and GP VIII, which will in turn ensure that such securities or economic benefits are provided to OPI VII and OPI VIII.

Investors’ Rights Agreement

In addition, OPI VII, Genesis, and certain other stockholders of the Issuer entered into an Amended and Restated Investors’ Rights Agreement with the Issuer (the “Investors’ Rights Agreement”), dated as of August 24, 2020. Pursuant to the Investors’ Rights Agreement and subject to the terms and conditions therein, the parties agreed that:

Demand Registration Rights

At any time beginning six months following the date of the effective date of the registration statement of the Issuer’s initial public offering, the holders of at least 30% of the registrable securities then outstanding of the Issuer may make a written request that the Issuer register some or all of their registrable securities, subject to certain specified conditions and exceptions, including that the aggregated gross offering price of such offering must exceed $15 million. The Issuer is required to use commercially reasonable efforts to effect the registration and will pay all registration expenses, other than underwriting discounts and commissions, related to any demand registration. The Issuer is not obligated to effect more than two of these registrations.

Piggyback Registration Rights

Whenever the Issuer proposes to file a registration statement under the Securities Act, including a registration statement on Form S-3 as discussed below, other than with respect to certain excluded registrations, OPI VII and Genesis will be entitled to notice of the registration and have the right, subject to limitations that the underwriters may impose on the number of Shares included in the registration, to include the Shares held by them in the registration.

Form S-3 Registration Rights

At any time after the Issuer is qualified to file a registration statement on Form S-3 under the Securities Act, and subject to limitations and conditions specified in the Investors’ Rights Agreement, holders of at least 20% of the registrable securities then outstanding may make a written request that the Issuer prepare and file a registration statement on Form S-3 covering their Shares, so long as the aggregate price to the public equal or exceeds $3 million. The Issuer is not obligated to effect more than two of these Form S-3 registrations in any 12-month period.

The foregoing description of the Investors’ Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Investors’ Rights Agreement, which is filed as Exhibit 3 and incorporated herein by reference.
