Item 4.Ownership

 

(a)Amount beneficially owned:

 

The Reporting Persons hold 11,364 shares of Series A Non-Voting Convertible Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”), convertible for an aggregate of 11,364,000 Shares. Each share of Series A Preferred Stock is convertible into 1,000 Shares. The Series A Preferred Stock may not be converted if, after such conversion, the Reporting Persons would beneficially own, as determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, in excess of 9.99% of the number of Shares then issued and outstanding (the “Beneficial Ownership Limitation”). As of the close of business on July 16, 2020, the Beneficial Ownership Limitation limits the aggregate conversion of Series A Preferred Stock by the Reporting Persons to 4,154,000 out of the 11,364,000 Shares underlying the Series A Preferred Stock owned by the Reporting Persons in the aggregate. In providing beneficial ownership described herein, the Reporting Persons have assumed that 4,154 shares of Series A Preferred Stock held by BVF would be converted, which would bring the Reporting Persons to the aggregate 9.99% limitation, and the remaining Series A Preferred Stock owned by BVF, BVF2 and Trading Fund OS would not be converted due to the Beneficial Ownership Limitation.

 

14

As of the close of business on July 16, 2020, (i) BVF beneficially owned 4,154,000 Shares, representing 4,154,000 Shares issuable upon the conversion of 4,154 shares of Series A Preferred Stock and excluding 1,782,000 Shares issuable upon the conversion of the remaining 1,782 shares of Series A Preferred Stock owned by it, (ii) BVF2 beneficially owned zero Shares, excluding 4,427,000 Shares issuable upon the conversion of the 4,427 shares of Series A Preferred Stock owned by it, and (iii) Trading Fund OS beneficially owned zero Shares, excluding 772,000 Shares issuable upon the conversion of the 772 shares of Series A Preferred Stock owned by it.

 

BVF GP, as the general partner of BVF, may be deemed to beneficially own the 4,154,000 Shares beneficially owned by BVF.

 

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own zero Shares.

 

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own zero Shares.

 

BVF GPH, as the sole member of each of BVF GP and BVF2 GP, may be deemed to beneficially own the 4,154,000 Shares beneficially owned by BVF.

 

Partners, as the investment manager of BVF, BVF2 and Trading Fund OS, and the sole member of Partners OS, may be deemed to beneficially own the 4,154,000 Shares beneficially owned by BVF, excluding 7,210,000 Shares issuable upon the conversion of 7,210 shares of Series A Preferred Stock owned in the aggregate by BVF, BVF2, Trading Fund OS, and a certain Partners managed account (the “Partners Managed Account”), which includes 229,000 Shares issuable upon the conversion of 229 shares of Series A Preferred Stock held in the Partners Managed Account.

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 4,154,000 Shares beneficially owned by Partners.

 

Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 4,154,000 Shares beneficially owned by BVF Inc.

 

The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of any securities owned by another Reporting Person. BVF GP disclaims beneficial ownership of the securities beneficially owned by BVF. BVF2 GP disclaims beneficial ownership of the securities beneficially owned by BVF2. Partners OS disclaims beneficial ownership of the securities beneficially owned by Trading Fund OS. BVF GPH disclaims beneficial ownership of the securities beneficially owned by BVF and BVF2. Each of Partners, BVF Inc. and Mr. Lampert disclaims beneficial ownership of the securities beneficially owned by BVF, BVF2, Trading Fund OS, and the Partners Managed Account, and the filing of this statement shall not be construed as an admission that any such person or entity is the beneficial owner of any such securities.

 

15
(b)Percent of class:

 

The following percentages are based on a denominator that is the sum of (i) 31,195,114 Shares outstanding as of July 2, 2020, as disclosed in Exhibit 10.1 to the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on July 6, 2020, (ii) 6,235,903 Shares issued in connection with a business combination as disclosed in the Issuer’s Current Report on Form 8-K filed with the Securities and Exchange Commission on July 6, 2020, and (iii) 4,154,000 Shares underlying certain shares of Series A Preferred Stock, as applicable.
