LA JOLLA, CA, Jan. 22, 2024 – CalciMedica, Inc. (CalciMedica or the Company) (Nasdaq: CALC), a clinical-stage biopharmaceutical company focused on developing novel calcium release-activated calcium (CRAC) channel inhibition therapies for acute and chronic inflammatory and immunologic diseases, today announced that it has entered into a securities purchase agreement with new and existing investors to raise up to approximately $55 million in gross proceeds that includes initial upfront funding of $20.4 million and up to an additional approximately $34.2 million upon exercise of accompanying warrants.

The financing includes participation from new healthcare-dedicated investors, including an affiliate of Deerfield Management, Soleus Capital, Stonepine Capital Management and Aisling Capital, as well as existing investors Sanderling Ventures and Bering Capital.

“We are excited about this vote of confidence from leading life science investors, which validates the progress we are making in the clinic with Auxora^™ targeting acute inflammatory and immunologic diseases,” said Rachel Leheny, Ph.D., Chief Executive Officer of CalciMedica. “This financing allows us to initiate clinical trials in AKI, a condition with significant unmet medical need, and brings us closer to our goal of making a meaningful difference in the lives of critically ill patients.”

JonesTrading Institutional Services LLC acted as the sole placement agent for the private placement. H.C. Wainwright & Co. acted as financial advisor to the Company.

Pursuant to terms of the securities purchase agreement, CalciMedica will issue an aggregate of 5,113,812 shares of its common stock (and, in lieu thereof, pre-funded warrants to purchase 351,352 shares of common stock) and accompanying warrants to purchase up to an aggregate of 5,465,164 shares of its common stock (or pre-funded warrants in lieu thereof) at a combined purchase price of $3.70 per share and accompanying warrants (or $4.3915 per share and accompanying warrants for directors, employees or consultants participating in the private placement), in accordance with the “Minimum Price” requirement as defined in the Nasdaq rules. The accompanying warrants consist of two tranches:

• Tranche A warrants to purchase up to 2,732,582 shares of common stock at an exercise price of $5.36 per share for an aggregate of up to approximately $14.7 million are required to be exercised by the earlier of 30 days following the announcement of topline data (expected 1H 2024) from the CalciMedica’s Phase 2b CARPO trial of Auxora in AP patients with accompanying systemic inflammatory response syndrome (SIRS) and December 31, 2024.

• Tranche B warrants to purchase up to 2,732,582 shares of common stock at an exercise price of $7.15 per share for an aggregate of up to approximately $19.5 million are required to be exercised by the earlier of 30 days following the announcement of topline data from the planned Phase 2 clinical trial of Auxora in AKI (expected to start in 1H 2024) and December 31, 2026.

The accompanying warrants are only exercisable in cash, except in limited circumstances. In lieu of shares of common stock, certain investors are purchasing pre-funded warrants at a combined purchase price of $3.6999 per pre-funded warrant and accompanying warrants, which equals the purchase price per share of common stock and accompanying warrant, less the $0.0001 per share exercise price of each pre-funded warrant. The private placement is expected to close in two closings with the initial closing on or about January 23, 2024 and the second closing expected on or about February 5, 2024, in each case, subject to satisfaction of customary closing conditions.

CalciMedica intends to use the upfront net proceeds from the private placement to fund the Company’s ongoing and planned Phase 2 clinical trials for Auxora in AP and AKI, respectively. The aggregate net proceeds (assuming exercise of all accompanying warrants) are expected to be sufficient to fund subsequent, potentially pivotal, clinical trials and other work in CalciMedica’s AP and AKI programs.
