Fortis Solutions Group

Fortis prints and converts pressure-sensitive labels, flexible packaging, shrink sleeves, and folding cartons for CPG, pharmaceutical, and industrial customers. The company operates as a consolidator of founder-owned print shops, bringing them onto shared systems while retaining local sales and service. Over 20 manufacturing facilities support a national customer base.

Main Post Partners, a San Francisco-based middle-market private equity firm, is the majority institutional sponsor. Fortis is not a fund or a family office — it is an operating company funded through equity and acquisition financing. John O. Wynne Jr. retains a significant ownership stake and runs day-to-day operations as CEO.

Fortis acquires founder-owned label and packaging companies through a proprietary origination network built over 25 years in the narrow-web printing industry. John Wynne and his corporate development team target shops with $5 million to $30 million in revenue that serve sticky, regulated end markets like pharma and specialty food. Deals are off-market or lightly brokered.
