(Case M.9577 — Genstar/Oak Hill Capital/Mercer ADV)

Candidate case for simplified procedure

(Text with EEA relevance)

(2019/C 329/05)


On 24 September 2019, the Commission received notification of a proposed concentration pursuant to Article 4 of Council Regulation (EC) No 139/2004 (1).

This notification concerns the following undertakings:

Genstar Capital Partners, LLC (‘Genstar’, United States),

Oak Hill Capital Management, LLC (‘Oak Hill’, United States),

Mercer Advisors Inc. (‘Mercer’, United States).

Genstar and Oak Hill acquire within the meaning of Article 3(1)(b) and 3(4) of the Merger Regulation joint control of the whole of Mercer.

The concentration is accomplished by way of purchase of shares.


The business activities of the undertakings concerned are:

for Genstar: private equity firm based in San Francisco, California, specialising in investments in middle market companies in financial services, healthcare, industrial technology and software industries,

It primarily services the mass-affluent and high-net-worth client and offers comprehensive wealth management solutions, including: financial planning, investment management, tax management, retirement income and benefits planning, and estate planning.
