#### Record Date
The record date is March 14, 2025.

#### Who Can Vote
Holders of our Common Shares as of the close of business on the record date are entitled to vote. For all matters submitted for a vote at the Annual Meeting, each Common Share is entitled to one vote. As of the close of business on March 14, 2025, we had 76,445,966 Common Shares that are issued, outstanding and entitled to vote at the Annual Meeting (including unvested restricted Common Shares).

#### Proxy Materials Provided Through Internet
We have provided access to our proxy materials over the Internet, and we are sending a Notice of Internet Availability of Proxy Materials (the "Notice") to our common shareholders of record who are entitled to vote at the Annual Meeting. We believe that posting these materials on the Internet enables us to provide shareholders with the information that they need more quickly. It also lowers our costs of printing and delivering these materials and reduces the environmental impact of the Annual Meeting. The Notice and this Proxy Statement summarize the information you need to know to vote by proxy or electronically at the Annual Meeting.

Shareholders of Record and Holders in "Street Name"

If you are a registered holder of Common Shares (i.e., you hold your shares directly in your name with our transfer agent) as of the close of business on the record date, the Notice was sent directly to you and you may vote your Common Shares electronically at the Annual Meeting or by proxy. If you hold Common Shares in "street name" through a brokerage firm, bank, broker-dealer or other intermediary (your "intermediary"), you are a beneficial owner, and the Notice was forwarded to you by your intermediary and you must follow the instructions provided by your intermediary regarding how to instruct the intermediary to vote your Common Shares. In the absence of specific instructions from you on how to vote your shares, your intermediary may not be able to vote your shares on certain matters.
