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.

No. Fortis is an industrial operating company, not an asset manager, family office, or private equity fund. Its capital is deployed entirely into manufacturing facilities, presses, and acquisitions of other label converters. There is no investment portfolio for third-party LPs.

Main Post Partners is the majority equity sponsor. The firm provides acquisition capital and strategic governance for Fortis's buy-and-build strategy. CEO John Wynne and his management team run the integrated plant network day-to-day. The partnership dates to Main Post's initial investment in 2015.

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.
