SPRING BRANCH, Texas, August 14, 2025 — Callan JMB INC. (NASDAQ: CJMB) (“Callan JMB” or the “Company”), an integrative logistics company empowering the healthcare industry and emergency management agencies through fulfillment, storage, monitoring, and cold chain logistics services, today announced its financial results for the second quarter ended June 30, 2025 and provided a business update.

“Callan JMB continues to solidify its position as a leading provider of specialized logistics solutions within high-growth opportunity markets, demonstrating our operational excellence through several key recent achievements,” commented Wayne Williams, CEO, Chairman & Founder of Callan JMB. “We were proud to form a strategic partnership with Revival to develop a broad supply platform for healthcare products, changing the way they are made available across the country. In July, we further expanded our market for global pharmaceutical cold chain logistics and clinical trial support by launching a subsidiary in India to establish temperature-controlled warehouses for storage and distribution. This international expansion positions us to import critical tissue samples for clinical trials and active pharmaceutical ingredients, helping address U.S. drug shortages.”

“Furthermore, we recently extended our emergency preparedness contract with the City of Chicago through June 2026 with $1.5 million in additional funding, bringing total contract value to $9.1 million. During the quarter, the Company appointed Christopher Shields as Senior Vice President, Emergency Preparedness & Response/Government Affairs, to grow our emergency preparedness & response operations into new U.S. cities, states, and other countries. We also successfully redistributed over 1,300 MMR II vaccine doses during the measles outbreak response with zero waste, showcasing our technological efficiency and sustainability credentials. Looking ahead, we remain focused on capitalizing on expansion opportunities within fast-growing industries, particularly GLP-1 pharmaceutical distribution, specialty compounding pharmacy logistics, and premium food packaging solutions. Callan JMB remains well-placed for sustained growth and market leadership through 2025,” added Mr. Williams.

Business Highlights:

● Formed strategic partnership with Revival to create integrated supply chain infrastructure for health, wellness, and longevity products, combining cold chain logistics expertise with consumer health innovation for scalable distribution solutions.

● Post quarter end launched Callan JMB Services (India) Private Limited with planned temperature-controlled warehouse in Pune, Maharashtra for pharmaceutical storage and distribution, already securing an agreement with Walker’s Pharmaceuticals Ltd. and working with additional Indian companies to facilitate U.S. market entry and manufacturing plant establishment.

● In July, the City of Chicago extended Callan JMB’s emergency preparedness contract through June 2026 with $1.5 million funding increase, bringing total contract value to $9.1 million and extending the seven-year partnership for continued management and distribution of health preparedness supplies.

● Appointed Christopher Shields, former Assistant Commissioner of the Chicago Department of Public Health, as Senior Vice President, Emergency Preparedness & Response/Government Affairs.

● Successfully redistributed over 1,300 MMR II vaccine doses from Chicago to Texas and New Mexico during measles outbreak response using specialized cold chain reusable shippers with zero waste, demonstrating emergency response capabilities and sustainable logistics solutions.

Financial Highlights for the Year Ended June 30, 2025:

● Revenues for the three months and six months ended June 30, 2025 were $1.7 million and $3.1 million, respectively. The decrease year-over-year in revenue was due to the decline in demand for our emergency preparedness services by certain states and local governments.

● Cost of revenues for the three months and six months ended June 30, 2025 were $1.0 million and 1.9 million, respectively. The decrease year-over-year in cost of revenue is in line with the decrease in revenues.

● Gross profit for the three months and six months ended June 30, 2025 were $0.6 million and 1.3 million, respectively.

● SG&A expenses for the three months and six months ended June 30, 2025 were $2.0 million and $3.9 million. The increase year-over-year was primarily driven by an increase in consulting, professional fees and marketing expenses related to the Company now being a public entity and adding the Company’s CEO to payroll for the first time, along with other senior staff hires to support future growth.

● Loss from operations for the three months and six months ended June 30, 2025 were $1.4 million and $2.6 million, respectively.

● Cash and cash equivalents for the period ended June 30, 2025 were $4.2 million.
