Insights

Corporate governance and leadership transition analyst

ATS faces a CFO change but has an experienced interim successor in place.

The resignation of long-serving CFO Ryan McLeod, effective February 15, 2026, is a notable leadership change for ATS Corporation. As CFOs oversee financial strategy, controls, and capital allocation, his departure after nearly 20 years can raise questions about continuity in financial leadership, even though the stated reason is pursuing an opportunity in an unrelated industry.

The company has designated Anne Cybulski, VP, Corporate Controller, as interim CFO, and highlighted her tenure since 2009 and prior interim CFO experience. This suggests familiarity with ATS’s systems and leadership team, which can support operational stability during the search for a permanent CFO. Future company communications about the timing and profile of the permanent successor will help clarify how ATS intends to position its finance function for the next phase of its growth.
