EXPLANATORY NOTE

Pursuant to Rule 13d-2 of the Securities Exchange Act of 1934, as amended, this Amendment No. 4 (“Amendment No. 4”) amends certain items of the Schedule 13D filed with the Securities and Exchange Commission (the “SEC”) on October 10, 2018, as amended by Amendment No. 1 filed with the SEC on July 16, 2019, Amendment No. 2 filed with the SEC on September 6, 2019 and Amendment No. 3 filed with the SEC on November 4, 2019 (as so amended, the “Original Schedule 13D”) relating to the Common Shares, $0.000037453 par value per share (the “Common Shares”), of Urovant Sciences Ltd. (the “Issuer”), which were beneficially owned by Roivant Sciences Ltd. (“Roivant” or the “Reporting Person”). This Amendment No. 4 amends the Original Schedule 13D on behalf of the Reporting Person to furnish the information set forth herein. Except as set forth below, all Items of the Original Schedule 13D remain unchanged. All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Original Schedule 13D.

Item 4. Purpose of Transaction

Item 4 of the Original Schedule 13D is hereby amended to add the following:

Consummation of the Transactions

As previously announced, on October 31, 2019, Roivant, Sumitomo Dainippon Pharma Co., Ltd. (“Sumitomo”) and certain of Roivant’s subsidiaries entered into a definitive agreement (the “Transaction Agreement”) related to the creation of a strategic alliance between the companies.

On December 27, 2019, Roivant closed the transactions contemplated by the Transaction Agreement (the “Transactions”) pursuant to which (i) Sumitomo indirectly acquired all of the Common Shares of the Issuer that were beneficially owned by Roivant (22,860,013 Common Shares), along with the equity interests owned by Roivant in four of its other subsidiaries, (ii) Roivant granted Sumitomo options to purchase, subject to certain exceptions set forth in the Transaction Agreement, Roivant’s existing equity interests in six other privately-held Roivant subsidiaries or affiliates and (iii) Roivant issued to Sumitomo common shares of Roivant.  In exchange, as contemplated by the Transaction Agreement, Sumitomo made an approximately $3.0 billion upfront cash payment to Roivant. Prior to the closing of the Transactions (the “Closing”), Roivant transferred all of the Common Shares that were directly held by Roivant to a wholly-owned subsidiary and, at the Closing, Roivant transferred all of the shares of such wholly owned subsidiary to Sumitomo. As a result, following the Closing, Roivant holds zero shares of Common Shares of the Issuer, directly or indirectly.

Other than as described above, Roivant does not have current plans or proposals that relate to or that would result in any of the transactions or other matters specified in clauses (a) through (j) of Item 4 of Schedule 13D.

The foregoing description of the Transaction Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Transaction Agreement, a copy of which is filed as Exhibit 7.04 to Amendment No. 3 to Schedule 13D filed with the SEC on November 4, 2019 and which is incorporated herein by reference.

Item 5. Interest in Securities of Issuer.

Subparagraphs (a), (b), (c) and (e) of Item 5 of the Original Schedule 13D are hereby amended and restated in their entirety to read as follows:

(a) See Items 11 and 13 of the cover pages to this Amendment No. 4, which are incorporated by reference in their entirety into this Item 5(a).

(b) See Items 7 through 10 of the cover pages to this Amendment No. 4, which are incorporated by reference in their entirety into this Item 5(b).

(c) The information set forth in Item 4 of this Amendment No. 4 is incorporated by reference into this Item 5(c).

(e) As of December 27, 2019, the Reporting Person ceased to be the beneficial owner of more than 5% of the outstanding Common Shares of the Issuer. Therefore, the filing of this Amendment No. 4 is the final amendment to the Original Schedule 13D and constitutes an exit filing for the Reporting Person.

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

Item 6 of the Original Schedule 13D is hereby amended to add the following:

The description of the Transactions set forth in Item 4 is incorporated by reference herein.
