ATB Financial Acquires Cormark Securities to Boost Capital Markets Reach

The deal moves Cormark’s CEO into a strategy role at ATB Capital Markets with its executive chair taking over as the unit’s chair to expand the firm’s North American presence.

Overview

  • Susan Streeter, Cormark’s chief executive, will assume ATB Capital Markets head of strategy and growth and Scott Lamacraft will become its executive chair.
  • ATB did not disclose financial terms of the deal although earlier reports suggested a minimum value of CAD 35 million.
  • According to LSEG Data & Analytics, Cormark led nine stock sales worth CAD 270 million in H1 2025, representing about 2.5% of Canada’s equity underwriting market.
  • The transaction, expected to close this fall pending regulatory approval, continues ATB’s acquisition-driven growth following its purchases of AltaCorp Capital in 2020 and BCV Asset Management in 2024.
  • The acquisition follows several senior departures at Cormark and underscores a broader consolidation trend among Canada’s regional investment dealers.
