Item 3.

Source and Amount of Funds or Other Consideration

 

Between March 31, 2021 and September 9, 2022, Vida II and Vida II-A purchased an aggregate of 1,284,322 and 35,638 of Series A preferred shares of Old Tectonic (as defined below) for an aggregate purchase price of $17,407,104. Between October 11, 2023 and December 22, 2023, Vida II and Vida II-A purchased SAFEs which converted into 465,144 and 12,907 shares of Old Tectonic at an aggregate purchase price of $5,927,399. On June 18, 2024, Vida II and Vida II-A purchased 123,407 and 3,424 common shares of Old Tectonic for an aggregate purchase price of 1,572,587. The source of funds for each of Vida II’s and Vida II-A’s purchases of shares of Old Tectonic securities was the contribution from its members.

 

On January 30, 2024, the Issuer, Tectonic Therapeutic, Inc. (“Old Tectonic”), and Alpine Merger Subsidiary, Inc., a direct wholly owned subsidiary of AVROBIO (“Merger Sub”) entered into the Agreement and Plan of Merger and Reorganization, dated as of January 30, 2024 (the “Merger Agreement”), pursuant to which Merger Sub merged with and into Old Tectonic, with Old Tectonic surviving as a direct wholly owned subsidiary of AVROBIO and the surviving corporation of the merger (the “Merger”). On June 20, 2024, the Issuer, Merger Sub and Old Tectonic consummated the transactions contemplated by the Merger Agreement. Effective at 4:00 p.m. Eastern Time on June 20, 2024, AVROBIO effected a 1-for-12 reverse stock split of its common stock (the “Reverse Stock Split”). Effective at 4:02 p.m. Eastern Time on June 20, 2024, the Issuer completed the Merger, and effective at 4:03 p.m. Eastern Time on June 20, 2024, the Issuer changed its name to Tectonic Therapeutic, Inc.

 

Under the terms of the Merger, immediately prior to the effective time of the Merger, each share of Old Tectonic’s preferred stock was converted into one share of Old Tectonic’s common stock. At the effective time of the Merger, each of these shares was converted into the right to receive 0.534419990 shares of the Issuer's common stock, after giving effect to the Reverse Stock Split.

 

The issuance of the shares of the Issuer’s common stock to the former stockholders of Old Tectonic, other than the shares issued in a pre-closing financing transaction which closed on June 20, 2024, was registered with the Securities and Exchange Commission (the “SEC”) on the Issuer’s Registration Statement on Form S-4 (File No. 333-277048), as amended.

 

 

Following the closing of the Merger, Vida II and Vida II-A directly owned 1,000,900 and 27,774 shares of Common Stock, respectively.

 

Item 4.

Purpose of Transaction

 

The Reporting Persons purchased the aforementioned securities for investment purposes with the aim of increasing the value of their investments and the Issuer. Subject to applicable legal requirements, one or more of the Reporting Persons may purchase additional securities of the Issuer from time to time in open market or private transactions, depending on its evaluation of the Issuer’s business, prospects and financial condition, the market for the Issuer’s securities, other developments concerning the Issuer, the reaction of the Issuer to the Reporting Persons’ ownership of the Issuer’s securities, other opportunities available to the Reporting Persons, and general economic, money market and stock market conditions. In addition, depending upon the factors referred to above, the Reporting Persons may dispose of all or a portion of their securities of the Issuer at any time (including by means of programs adopted pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934 (the “Act”)). Each of the Reporting Persons reserve the right to increase or decrease its holdings on such terms and at such times as each may decide.

 

Except as set forth in this Item 4 and Item 6 below, none of the Reporting Persons have a present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act. However, each of the Reporting Persons reserves the right to propose or participate in future transactions which may result in one or more of such actions, including but not limited to, an extraordinary corporate transaction, such as a merger, reorganization or liquidation, sale of a material amount of assets of the Issuer or its subsidiaries, or other transactions which might have the effect of causing the Common Stock to become eligible for termination of registration under Section 12(g) of the Act. The Reporting Persons also retain the right to change their investment intent at any time, to acquire additional shares of Common Stock or other securities of the Issuer from time to time, or to sell or otherwise dispose of all or part of the Common Stock beneficially owned by them (or any shares of Common Stock into which such securities are converted) in any manner permitted by law. The Reporting Persons may engage from time to time in ordinary course transactions with financial institutions with respect to the securities described herein.
