The latest announcement is out from White Mountains Insurance Group ( (WTM) ).
On February 26, 2026, Bishop Street Underwriters, a RedBird Capital Partners portfolio company and diversified platform of managing general agents and niche underwriting teams in the property and casualty sector, closed a $125 million structured capital investment from White Mountains Insurance Group. Bishop Street said the capital injection follows a strong 2025, when it surpassed $650 million in gross written premium with industry-leading organic growth and a sub-50% portfolio loss ratio.
Executives from Bishop Street, White Mountains and RedBird framed the deal as a strategic partnership aimed at accelerating Bishop Street’s acquisition-driven expansion, de novo program launches and global footprint in 2026 and beyond. The investment underscores growing investor interest in MGA platforms and is expected to bolster Bishop Street’s ability to capitalize on secular growth tailwinds in specialty insurance distribution, with potential benefits for its operating partners and broader market positioning.
