AVAILABILITY OF PROXY MATERIALS
In accordance with SEC rules, we are using the internet as our primary means of furnishing
proxy materials to stockholders. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials with instructions for accessing
the proxy materials, including our Proxy Statement and Annual Report for the year ended December 31, 2022, and voting via the internet. The Notice of Internet Availability of Proxy Materials also provides information on how stockholders may
obtain paper copies of our proxy materials if they so choose. This makes the proxy distribution process more efficient and less costly and helps conserve natural resources. If you previously elected to receive our proxy materials electronically,
these materials will continue to be sent via email unless you change your election.
MULTIPLE STOCKHOLDERS SHARING THE SAME ADDRESS —
“HOUSEHOLDING”
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to
satisfy the delivery requirements for proxy statements with respect to two or more stockholders sharing the same address by delivering a single set of proxy materials addressed to those stockholders. This process, which is commonly referred to as
“householding,” may potentially provide extra convenience for stockholders and cost savings for companies or the intermediary.
You may receive proxy materials through an intermediary who uses householding to deliver
proxy materials. If so, a single copy of the proxy materials, including the Notice of Internet Availability of Proxy Materials, may be delivered to
