Are Weiser and Mazars Making a Run for the Global 6?

As you’re aware, we’re obsessed with the notion of the ‘Global 6 Accounting Organization’ moniker. On the one hand it’s a little silly but on the other, many non-Big 4 firms are making a legitimate run to expand their international exposure.

The latest attempt at piercing the Global 6 comes courtesy of a possible merger between the firms Weiser and Mazars. According to Weiser’s website, the two firms currently have an affiliate relationship:

Mazars is an international, integrated, independent organization, ranked fifth largest in Europe. Weiser has established a joint venture with Mazars utilizing its 10,500 professionals in over 50 countries, as needed, to expand the firm’s global reach.


According to the FT, the combined firms will make a push a building their firm around providing IFRS adoption services:

Mazars and Weiser, which have had a joint venture agreement for a decade, decided to merge with the aim of building a new US practice focusing on the adoption of International Financial Reporting Standards by US companies, according to sources.

Weiser partners believe they will have an advantage in the US market working with European partners with extensive experience of IFRS.

We have a little secret to share with the Weiser partners: The Big 4 has European partners will extensive experience in IFRS too. They’re drooling for the IFRS adoption business just like you so hope you’re coming with super-secret plan that will give you a real advantage.

We contacted a Mazars spokesperson who confirmed that the talks were on-going but told us that the contract has yet to be finalized and that both partnerships will have to vote on the proposal. The vote is tentatively set for February or March.

Whether this is the “mega-merger” that was predicted back in August or not we don’t know but the combined firms would have total revenues of $1.3 billion, according to the FT. That’s just a fraction of the Big 4 revenues but it could put them in close competition with the likes of Grant Thornton, RSM International, and BDO.

We’ll continue to keep you updated on the progress of the talks as we learn them.
