Strategic extension reinforces recurring revenue visibility and growing demand for preparedness, continuity, and cold chain infrastructure

Spring Branch, TX, May 20, 2026 (GLOBE NEWSWIRE) -- 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 the expansion and extension of an existing long-term public sector infrastructure engagement valued at approximately $175,000 per month over the next six months.

The agreement represents approximately $1.05 million in projected recurring revenue over the next six months, tied to continued operational support, specialized storage, preparedness operations, monitoring, and mission-critical logistics services under an active governmental infrastructure initiative.

The Company noted that the engagement was expanded through an amendment extending operational support through the second half of 2026.

Originally established in 2018, the engagement reflects a long-standing operational relationship supporting preparedness infrastructure, regulated supply chain continuity, specialized storage capabilities, and rapid-response logistics services. The latest extension reinforces the growing role third-party infrastructure providers play in supporting operational readiness and continuity planning across government and regulated industry environments.

"Across the country, organizations are recognizing that preparedness, continuity planning, and cold chain resilience are no longer optional infrastructure components — they are mission-critical," said Wayne Williams, President & CEO of Callan JMB. "We believe demand for specialized operational support will continue growing as agencies and institutions modernize how they manage emergency readiness, regulated logistics, and infrastructure continuity."

Industry demand for preparedness infrastructure and specialized cold chain support services continues to expand as municipalities, healthcare systems, government agencies, and regulated industries modernize continuity planning and emergency response capabilities. Increasing regulatory complexity, temperature-sensitive assets, and the need for rapid deployment logistics have accelerated reliance on specialized third-party infrastructure partners capable of supporting scalable, compliant, and resilient operations.

Callan JMB believes the continued expansion of preparedness-focused logistics contracts reflects a broader national trend as public agencies and regulated industries increasingly prioritize resilient infrastructure, emergency continuity planning, and specialized operational capabilities. As supply chains become more complex and operational readiness requirements continue to increase, demand for scalable third-party infrastructure support continues to grow across both public- and private-sector environments.

Callan JMB expects continued momentum across both public and private sector opportunities as organizations prioritize supply chain resilience, preparedness infrastructure, operational modernization, and continuity planning.
