Item 4.Ownership

 

(a)Amount beneficially owned:

 

As of the close of business on January 28, 2019, the Reporting Persons hold 217,877 warrants, exercisable for an aggregate of 217,877 Shares (the “Warrants”). Each Warrant entitles the holder thereof to acquire one (1) Share for an exercise price of $12.74 per Share, subject to adjustments as provided under the terms of the Warrants. The Warrants are only exercisable to the extent that the holder, together with its affiliates and any other person or entity acting as a group, would not beneficially own more than 4.99% of the outstanding Shares after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the Warrants (the “Beneficial Ownership Limitation”). As of January 28, 2019, the Beneficial Ownership Limitation limits the aggregate exercise of the Warrants by the Reporting Persons to zero out of the 217,877 Shares underlying the Warrants owned by the Reporting Persons in the aggregate. BVF holds Warrants to purchase 112,610 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation. BVF2 holds Warrants to purchase 92,035 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation. Trading Fund OS holds Warrants to purchase 13,232 additional Shares which are excluded herein as a result of the Beneficial Ownership Limitation.

Partners, as the general partner of BVF, BVF2, the investment manager of Trading Fund OS, and the sole member of Partners OS, may be deemed to beneficially own the 1,201,718 Shares beneficially owned in the aggregate by BVF, BVF2, Trading Fund OS, and a certain Partners managed account (the “Partners Managed Account”), including 72,263 Shares held in the Partners Managed Account.

 

BVF Inc., as the general partner of Partners, may be deemed to beneficially own the 1,201,718 Shares owned by Partners.

 

Mr. Lampert, as a director and officer of BVF Inc., may be deemed to beneficially own the 1,201,718 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. Partners OS disclaims beneficial ownership of the Shares beneficially owned by Trading Fund OS. Each of Partners, BVF Inc. and Mr. Lampert disclaims beneficial ownership of the Shares 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.

 

(b)Percent of class:

 

This percentage is calculated based upon 18,559,164 Shares outstanding, which is the sum of: (i) 13,852,464 Shares outstanding as of November 1, 2018, as set forth in the Issuer’s quarterly report filed on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”) on November 8, 2018 and (ii) 4,706,700 Shares issued, as disclosed in the Issuer’s current report on Form 8-K filed with the SEC on January 16, 2019.

 

As of the close of business on January 28, 2019 (i) BVF beneficially owned approximately 3.1% of the outstanding Shares, (ii) BVF2 beneficially owned approximately 2.5% of the outstanding Shares, (iii) Trading Fund OS beneficially owned less than 1% of the outstanding Shares, (iv) Partners OS may be deemed to beneficially own less than 1% of the outstanding Shares, and (v) each of Partners, BVF Inc. and Mr. Lampert may be deemed to beneficially own approximately 6.5% of the outstanding Shares (less than 1% of the outstanding Shares is held in the Partners Managed Account).
