However, if the date of the 2026 Annual Meeting is more than 30 days before or more than 60 days after the one-year anniversary of the date of our 2025 Annual Meeting, for the stockholder notice to be timely, it must be delivered to the Corporate Secretary at our principal executive offices not earlier than 5:00 p.m. Eastern Time on the 105th day prior to the date of the 2026 Annual Meeting and not later than 5:00 p.m. Eastern Time on the later of (1) the 90th day prior to such annual meeting or (2) the close of business on the tenth day following the day on which public announcement of the date of such meeting is first made by us.

“Householding”—Stockholders Sharing the Same Address

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, multiple stockholders who reside at the same address may receive a single copy of our Annual Report on Form 10-K and proxy materials, unless the affected stockholder has provided other instructions.

We expect that a number of brokers with account holders who are our stockholders will be “householding” our Annual Report on Form 10-K and proxy materials. A single set of Annual Report on Form 10-K and other proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting their broker. Stockholders may revoke their consent at any time by contacting Equiniti Trust Company, LLC, through their website at www.equiniti.com or by phone at (800) 468-9716.

Upon written or oral request, we will undertake to promptly deliver a separate copy of this Proxy Statement, proxy card, Annual Report on Form 10-K and other proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the proxy statement, proxy card and, if applicable, Annual Report on Form 10-K and other proxy materials, you may write our Investor Relations Department at CalciMedica, Inc., 505 Coast Boulevard South, Suite 307 La Jolla, CA 92037, Attn: Investor Relations, or submit a request on our website at ir.calcimedica.com/ or calcimedica@argotpartners.com.

Any stockholders who share the same address and currently receive multiple copies of our Notice or Annual Report on Form 10-K and other proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record to request information about “householding” or our Investor Relations Department at the address listed above.
