Item 1.01. Entry into a Material Definitive Agreement.
On November 3, 2025, Ultragenyx Pharmaceutical Inc. (the “Company”) and its wholly owned subsidiary Rare Delaware Inc. (“Seller”) entered into a Royalty Purchase Agreement (the “Agreement”) with OCM LS23 Holdings LP, an investment vehicle of OMERS, pursuant to which OMERS paid $400 million in cash to Seller in consideration for the right (the “Purchased Interest”) to receive (i) an additional 25% of the future royalty payments due to the Company from Kyowa Kirin Co., Ltd. (“KKC”) based on net sales of Crysvita® in the United States and Canada under the terms of the Company’s Collaboration and License Agreement with KKC dated as of August 29, 2013, as amended (the “License Agreement”) from and after January 1, 2028 and (ii) 30% of the future royalty payments due to the Company from KKC based on net sales of Crysvita® in the United States and Canada under the terms of the Company’s License Agreement, from and after the date on which the Royalty Cap (as defined in the Royalty Purchase Agreement, dated as of July 14, 2022, by and among the Company, Seller and OCM LS23 Holdings LP) is met (collectively, the “Royalties”). The Agreement will automatically expire, and the payment of the Purchased Interest to OMERS will cease, on the earlier of (1) the date on which aggregate payments actually received by OMERS equals 1.55 times the purchase price ($620 million), or (2) the date of payment of the Purchased Interest with respect to the last Royalties due to the Company under the License Agreement. In connection with the foregoing, OMERS granted the Company an option, exercisable at any time for a two-year period, to repurchase in whole the Purchased Interest for an amount equal to 1.35 times the purchase price ($540 million).
The Agreement contains other customary terms and conditions, including representations and warranties, covenants, and indemnification obligations in favor of each party.
