Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Nominee

If your shares are held in “street name” (meaning the shares are held in the name of a bank, broker, or other nominee who is the record holder), you should have received a WHITEvoting instruction form from that organization rather than from us. Simply follow the voting instructions to ensure that your vote is counted. Prior to the Annual Meeting, you will be able to vote by mail, via the Internet or by telephone. You may also obtain a “legal proxy” from your broker, bank, or other nominee and register in advance to attend and vote at the Annual Meeting by following the instructions described below. Even if you wish to attend the Annual Meeting, we urge you to vote your shares in advance of the Annual Meeting by following the instructions on your WHITEvoting instruction form.

You may hold your shares in more than one account and may receive separate proxy cards or voting instruction forms for each of those accounts. To ensure that all of your shares are represented at the Annual Meeting, we recommend that you submit every WHITEproxy card or WHITEvoting instruction form you receive.

If you have obtained a legal proxy and wish to participate in the Annual Meeting, you must pre-register by 9:00 a.m. Eastern Time on July 17, 2025, at www.cesonlineservices.com/sonm25_vm.
