(NASDAQ: CJMB) (“Callan JMB” or the “Company”), an integrative logistics company supporting the healthcare industry, government agencies and emergency-management organizations through fulfillment, storage, monitoring and cold-chain logistics services, today announced the successful completion of emergency preparedness support for the City of Chicago during the 2026 Lollapalooza weekend. The engagement continues Callan JMB’s longstanding work supporting the City during major public events and other periods requiring heightened preparedness. The Company brings extensive experience and proven capabilities to the complex logistical and operational requirements associated with large gatherings in one of the country’s most populous urban environments. Lollapalooza welcomed approximately 460,000 attendees to Chicago’s Grant Park over four days and featured 172 musical acts. The festival represents one of the city’s largest annual events and generates significant economic activity across Chicago’s hospitality, tourism, transportation and retail sectors. The festival also coincided with an exceptionally busy weekend across the city. The Chicago Cubs hosted the New York Yankees for a three-game series at Wrigley Field, the Chicago Fire faced Charlotte FC at Soldier Field on Saturday, and Liverpool played Leeds United in an exhibition match at Soldier Field on Sunday. The concentration of major events brought hundreds of thousands of residents and visitors into Chicago’s downtown, lakefront and entertainment districts, creating a heightened preparedness environment across multiple venues. Successfully supporting a weekend of this scale requires advance planning, coordinated resources and the ability to respond efficiently as conditions evolve. “Callan JMB has supported the City of Chicago during major events for years, and we are proud to continue that work during another successful Lollapalooza weekend,” said Scott Bullard, Chief Operating Officer. “Preparedness at this scale depends on experienced partners, proven procedures and resources that are ready when needed, and we value the continued trust placed in our team to support these important operations.” "On behalf of Callan JMB, I want to sincerely thank all of the employees who supported this year's Lollapalooza event in the City of Chicago.

We greatly appreciate the dedication, professionalism, and hard work of our team members who made this year's effort a success."
