Item 3. Source and Amount of Funds or Other Consideration.

 

In connection with Avista’s initial public offering in August 2021, Avista Sponsor (i) purchased 5,750,000 class B ordinary shares, par value $0.0001 per share, of Avista (“Avista Class B Shares”) for an aggregate $25,000, (ii) transferred an aggregate 105,000 shares to the independent director nominees of Avista at their original purchase price and (iii) purchased 8,233,333 private placement warrants (the “PP Warrants”) for an aggregate $12,349,999.50, with each PP Warrant exercisable to purchase after the Domestication (as defined below) one share of common stock for $11.50 per share. The PP Warrants by their terms become exercisable (including by cash settlement) 30 days following the Closing Date (as defined below). Additionally, the Avista Sponsor may notify the Issuer in writing in the event it elects to be subject to a requirement that it will not have the right to exercise such PP Warrants, to the extent that after giving effect to such exercise, the Sponsor (together with its affiliates), would beneficially own in excess of 9.8% of the common stock issued and outstanding immediately after giving effect to such exercise. The foregoing summary of the terms of the PP Warrants does not purport to be complete and is qualified in its entirety by reference to full terms of the PP Warrants set forth in the Warrant Agreement, dated August 9, 2021, between Avista and Continental Stock Transfer & Trust Company, a copy of which is included as an exhibit to this Schedule 13D and is incorporated herein by reference.

 

 

In accordance with the business combination completed on November 1, 2022 (the “Closing Date”), as contemplated by that certain Agreement and Plan of Merger, dated as of March 23, 2022 (the “Merger Agreement”), by and among Avista, Ligand Pharmaceuticals Incorporated, OmniAb, Inc. (“Legacy OmniAb”), and Orwell Merger Sub Inc., Avista domesticated (the “Domestication”) as a Delaware corporation and changed its name to “OmniAb, Inc.” Pursuant to the Domestication, the 5,645,000 Avista Class B Shares directly owned by Avista Sponsor converted automatically, on a one-for-one basis, into 5,645,000 shares of common stock (the “Founder Shares”).

 

In connection with the Merger Agreement and Amended and Restated Forward Purchase Agreement, dated March 23, 2022, by and among Avista, Avista Sponsor and Legacy OmniAb (the “A&R Forward Purchase Agreement”), on November 1, 2022, Avista Sponsor purchased an aggregate 10,172,934 shares of common stock and an aggregate 3,112,156 warrants (each warrant exercisable to purchase one share of common stock on the same terms as the PP Warrant) (the “FPA Warrants” and together with the PP Warrants, the “Warrants”) for aggregate cash consideration of $101,729,340.

 

The purchases of the shares of common stock and FPA Warrants by the Avista Sponsor pursuant to the A&R Forward Purchase Agreement were funded by equity contributions of the limited partners of the Avista Sponsor.

 

Item 4. Purpose of the Transaction.

 

The information set forth or incorporated by reference in Items 3, 5 and 6 of this Schedule 13D is incorporated by reference into this Item 4.

 

The shares of common stock reported on this Schedule 13D were acquired for investment purposes. The Reporting Persons expect to evaluate on an ongoing basis the Issuer’s financial condition and prospects and their respective interests in, and intentions with respect to, the Issuer and their respective investments in the securities of the Issuer, which review may be based on various factors, including the Issuer’s business and financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s securities in particular, as well as other developments and other investment opportunities. Accordingly, each Reporting Person reserves the right to change its intentions, as it deems appropriate. In particular, each Reporting Person may at any time and from time to time subject to compliance with the terms of the A&R Registration Rights Agreement (as defined below) and the Sponsor Letter Agreement (as defined below), in the open market, in privately negotiated transactions or otherwise, increase its holdings in the Issuer or dispose of all or a portion of the securities of the Issuer that such Reporting Person now owns or may hereafter acquire, including sales pursuant to the exercise of the registration rights provided for in the A&R Registration Rights Agreement. In addition, the Reporting Persons may engage in discussions with management and members of the board of directors of the Issuer (the “Issuer Board”) regarding the Issuer, including, but not limited to, the Issuer’s business and financial condition, results of operations and prospects. The Reporting Persons may take positions with respect to and seek to influence the Issuer regarding the matters discussed above. Such suggestions or positions may include one or more plans or proposals that relate to or would result in any of the actions required to be reported herein.

 

The Reporting Persons may have the ability, as a result of their holding shares of common stock, to influence or determine the vote with respect to significant matters involving the Issuer, including the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. In addition, Joshua Tamaroff, an employee of an affiliate of the Reporting Persons, serves on the Issuer Board as a representative of the Reporting Persons, and may have influence over the corporate activities of the Issuer, including activities which may relate to items described in paragraphs (a) through (j) of Item 4 of Schedule 13D. Certain plans or proposals may from time to time be discussed or considered by the directors of the Issuer, in each of their fiduciary capacities as a director of the Company.

The beneficial ownership information that follows is as of November 1, 2022, based on 114,820,859 shares of common stock outstanding (such outstanding shares based on information provided to the Reporting Persons by the Issuer) plus 11,345,489 shares of common stock issuable upon the exercise of 11,345,489 Warrants held by Avista Sponsor.

 

As of November 14, 2022, the Reporting Persons beneficially owned an aggregate of 27,163,423 shares of common stock (comprised of 15,817,934 shares of common stock directly held by Avista Sponsor and 11,345,489 shares of commons stock issuable upon the exercise of 11,345,489 Warrants directly held by Avista Sponsor), which represents 21.5% of the outstanding common stock.

 

(c) Other than as disclosed in this Schedule 13D, the Reporting Persons have not effected any transactions in shares of common stock during the past 60 days.

 

(d) Under certain circumstances, partners or members of the Reporting Persons, as applicable, could have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, shares of common stock owned by such Reporting Persons.

Item 6.  Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

 

The information set forth in Items 2, 3, 4 and 5 of this Schedule 13D is hereby incorporated by reference into this Item 6.

 

A&R Registration Rights Agreement

 

In accordance with the Merger Agreement, on November 1, 2022, the Issuer, Avista Sponsor and the other parties thereto entered into Amended and Restated Registration and Shareholder Rights Agreement (the “A&R Registration Rights Agreement”). The A&R Registration Rights Agreement requires the Issuer to file a registration statement, as soon as practicable but in any event within 30 days after the Closing Date, to permit the public resale of all the Registrable Securities (as defined in the A&R Registration Rights Agreement) held by Avista Sponsor and other parties to the A&R Registration Rights Agreement from time to time as permitted by Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”). Avista Sponsor also has certain customary “piggy back” registration rights with respect to registration statements filed subsequent to the Closing Date. The A&R Registration Rights Agreement also provides that the Issuer will pay all expenses (except for certain selling expenses) relating to such registrations and indemnify the registration rights holders against (or make contributions in respect of) certain liabilities which may arise under the Securities Act.

 

Further, subject to certain exceptions, the A&R Registration Rights Agreement provides for certain restrictions on transfer with respect to the securities of the Issuer, including Founder Shares and Warrants. Such restrictions end (i) with respect to the Founder Shares, at the earliest of (A) one year after the Closing Date and (B) the first date on which (x) the last reported sale price of a share of the common stock equals or exceeds $12.00 per share for any 20 trading days within any 30-trading day period commencing at least 150 days after the Closing Date or (y) the Issuer completing a liquidation, merger, share exchange, reorganization or other similar transaction that results in the Issuer stockholders having the right to exchange their shares of common stock for cash, securities or other property and (ii) with respect to the Warrants that are held by Avista Sponsor (or permitted transferees under the A&R Registration Rights Agreement), and any of the shares of common stock issued or issuable upon the exercise or conversion of such warrants and that are held by Avista Sponsor (or permitted transferees under the A&R Registration Rights Agreement), the period ending 30 days after the Closing Date.

 

 

Sponsor Insider Agreement

 

Under the letter agreement, dated March 23, 2022, among Avista, Avista Sponsor, Legacy OmniAb and other parties, the “Sponsor Insider Agreement”), Avista Sponsor agreed to subject 1,293,299 Founder Shares (the “Sponsor Earnout Shares”) to forfeiture if an applicable Sponsor Triggering Event (as defined below) has not occurred with respect to such Sponsor Earnout Shares by the fifth anniversary of the Closing Date.

 

“Sponsor Triggering Event” means (a) with respect to 50% of the Sponsor Earnout Shares, the date on which the volume weighted average price (“VWAP”) of the common stock equals or exceeds $12.50 on any 20 trading days in any 30 consecutive trading-day period, and (b) with respect any Sponsor Earnout Shares for which a Sponsor Triggering Event has not occurred with respect to clause (a), the date on which the VWAP of the common stock equals or exceeds $15.00 on any 20 trading days in any 30 consecutive trading-day period; provided, that in the event of a Change of Control (as defined in the Merger Agreement) between the date of the Closing Date to and including the fifth anniversary of the Closing Date pursuant to which the Issuer or any of its stockholders have the right to receive, directly or indirectly, cash, securities or other property attributing a value of at least $12.50 (with respect to 50% of the Sponsor Earnout Shares) or $15.00 (with respect to all Sponsor Earnout Shares) per share of common stock, as agreed in good faith by Avista Sponsor and the Issuer Board, then a Sponsor Triggering Event shall be deemed to have occurred immediately prior to such Change of Control.

 

The Sponsor Insider Agreement also provides, among other things, that the holders of the Sponsor Earnout Shares may not transfer their Sponsor Earnout Shares until the date in which vesting has occurred, other than in a distribution made by Avista Sponsor to its members in accordance with its governance documents and the A&R Registration Rights Agreement.

 

The Sponsor Insider Agreement will terminate on the vesting in full of all Sponsor Earnout Shares.
