Item 4.

Ownership

 

(a)

Amount beneficially owned:

 

As of the close of business on December 31, 2023, the Reporting Persons and a certain Partners managed account (the “Partners Managed Account”) held an aggregate of 4,358 shares of Series F-3 Convertible Preferred Stock (the “Series F-3 Preferred Stock”), convertible into an aggregate of 968,444 Shares at a conversion price of $4.50 per Share. A holder of the Series F-3 Preferred Stock shall not have the right to convert any portion of the Series F-3 Preferred Stock and such Series F-3 Preferred Stock shall not be automatically converted, to the extent that after giving effect to such conversion, such holder thereof, together with its affiliates, any other persons acting as a group together, and any other persons whose beneficial ownership of Shares would be aggregated with such holder and the other attribution parties for purposes of Section 13(d) of the Securities Exchange Act of 1934 (the “Exchange Act”) would beneficially own in excess of 9.99% of the Shares outstanding immediately after giving effect to such conversion, excluding for purposes of such determination Shares which would be issuable upon conversion of the remaining, unconverted portion of all series of Series F Convertible Preferred Stock of the Issuer beneficially owned (the “Beneficial Ownership Limitation”). As of the close of business on December 31, 2023, the Beneficial Ownership Limitation does not limit the conversion of any of the Series F-3 Preferred Stock held by the Reporting Persons and the Partners Managed Account.

 

As of the close of business on December 31, 2023, the Reporting Persons held preferred stock tranche B warrants (the “Tranche B Warrants”), exercisable into an aggregate of 6,250 shares of Series F-4 Convertible Preferred Stock (the “Series F-4 Preferred Stock”), which in turn are convertible into an aggregate of 1,041,667 Shares at a conversion price of $6.00 per Share. The Tranche B Warrants are exercisable at any time, have an exercise price of $1,000 per share of Series F-4 Preferred Stock, and expire on the earlier of (i) twenty-one (21) days following the date of the Issuer’s public announcement of recording at least $10,000,000 in quarterly U.S. revenue from the commercialization of HEPZATO and (ii) March 31, 2026. The conversion of the shares of Series F-4 Preferred Stock underlying the Tranche B Warrants are subject to the Beneficial Ownership Limitation. As of the close of business on December 31, 2023, assuming all the Tranche B Warrants held in the aggregate by the Reporting Persons and the Partners Managed Account were exercised for Series F-4 Preferred Stock, the Beneficial Ownership Limitation limits the conversion of the Series F-4 Preferred Stock held by the Reporting Persons and the Partners Managed Account to 393,833 out of the 1,041,667 Shares underlying the Series F-4 Preferred Stock held by them.

 

As of the close of business on December 31, 2023, (i) BVF beneficially owned 1,433,024 Shares, including (a) 519,111 Shares underlying the Series F-3 Preferred Stock, and (b) 393,833 Shares underlying certain Series F-4 Preferred Stock, which in turn are underlying certain Tranche B Warrants held by it, and excluding 167,333 Shares underlying certain Series F-4 Preferred Stock, which in turn are underlying certain Tranche B Warrants held by it, (ii) BVF2 beneficially owned 790,282 Shares, including 394,222 Shares underlying the Series F-3 Preferred Stock held by it, and excluding 127,667 Shares underlying the Series F-4 Preferred Stock, which in turn are underlying the Tranche B Warrants held by it, and (iii) Trading Fund OS beneficially owned 90,229 Shares, including 44,222 Shares underlying the Series F-3 Preferred Stock held by it, and excluding 15,167 Shares underlying the Series F-4 Preferred Stock, which in turn are underlying the Tranche B Warrants held by it.

 

BVF GP, as the general partner of BVF, may be deemed to beneficially own the 1,433,024 Shares beneficially owned by BVF.

 

BVF2 GP, as the general partner of BVF2, may be deemed to beneficially own the 790,282 Shares beneficially owned by BVF2.

 

Partners OS, as the general partner of Trading Fund OS, may be deemed to beneficially own the 90,229 Shares beneficially owned by Trading Fund OS.

 

BVF GPH, as the sole member of each of BVF GP and BVF2 GP, may be deemed to beneficially own the 2,223,306 Shares beneficially owned in the aggregate by BVF and BVF2.

 

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 2,338,426 Shares beneficially owned in the aggregate by BVF, BVF2 and Trading Fund OS and held in the Partners Managed Account, including 24,891 Shares held in the Partners Managed Account, including 10,889 Shares underlying the Series F-3 Preferred Stock held in the Partners Managed Account, and excluding 5,167 Shares underlying the Series F-4 Preferred Stock, which in turn are underlying the Tranche B Warrants held in the Partners Managed Account.

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 2,338,426 Shares beneficially owned by Partners.

 

Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 2,338,426 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 Shares owned by another Reporting Person. BVF GP disclaims beneficial ownership of the Shares beneficially owned by BVF. BVF2 GP disclaims beneficial ownership of the Shares beneficially owned by BVF2. Partners OS disclaims beneficial ownership of the Shares beneficially owned by Trading Fund OS. BVF GPH disclaims beneficial ownership of the Shares beneficially owned by BVF and BVF2. Each of Partners, BVF Inc. and Mr. Lampert disclaims beneficial ownership of the Shares beneficially owned by BVF, BVF2 and Trading Fund OS and held in 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.
