Moore Global Names Tomasi as New Board Chair
Accounting and advisory firms in the network will see a new global governance chair take office on 1 January 2027.
Updated on Nov. 4, 2026 in People
Moore Global has appointed David Tomasi, currently chair of Moore Australia, as chair of its Global Board, succeeding Andy Armanino, who stepped down after seven years in the role. Tomasi takes up the position on 1 January 2027.
Why it matters
The chair role sets governance direction for a network of more than 37,000 employees across 568 offices, which matters to firms that partner with, refer to, or compete alongside Moore Global members. The handover is a planned leadership transition rather than a change in strategy announced in the source.
Moore Global's network spans more than 37,000 employees across 568 offices in 119 countries. The outgoing chair, Andy Armanino, served seven years in the role before stepping down.

Timeline
November 2026: Moore Global announces the appointment of David Tomasi as Global Board chair.
1 January 2027: Tomasi formally takes up the Global Board chair role, succeeding Andy Armanino.
Market Landscape
Moore Global operates as a network of independently owned member firms rather than a single integrated company, so its global board chair coordinates across national practices. Moving a leader from a national member, here Moore Australia, into the global chair role reflects how such networks typically fill governance positions.
For firms working with or within Moore Global's network, the leadership handover is unlikely to change day-to-day operations in the near term. Operators who rely on network-level standards should monitor whether the incoming chair signals any shift in global priorities.
The takeaway
The chair transition is a planned succession and does not, on the source's account, alter network structure. Firms that depend on Moore Global's standards should watch for any strategic direction Tomasi sets once he takes office on 1 January 2027.
What happens next
David Tomasi takes up the Global Board chair role on 1 January 2027.
