Dealmaker Exits Adamantem Capital Amid Busy Acquisition Spree

Sydney - Adamantem Capital, one of Australia's most active private equity firms, has lost a key dealmaker as it navigates a flurry of investment activity.

David Brennecke, who joined Adamantem two years ago after a stint at rival Affinity Equity Partners, has resigned from the buyout firm, according to people familiar with the matter. His departure comes as Adamantem has taken stakes in several ASX-listed companies over the past year, including a $300 million acquisition of a majority stake in engineering group Valmec.

Adamantem, led by managing directors Anthony Kerwick and Rob Koczkar, has been one of the most active private equity investors in Australia of late. The firm, which raised $1 billion for its third fund in 2021, has deployed capital across sectors including healthcare, industrials, and business services.

Brennecke's exit is the latest high-profile departure from Australia's competitive private equity landscape. Earlier this year, Quadrant Private Equity lost two senior partners, while Allegro Funds saw the exit of its co-founder and managing director Damien Hodgkinson.

Adamantem declined to comment on Brennecke's resignation. The firm, which was founded in 2016, has built a reputation for taking control stakes in mid-market companies and working closely with management teams to drive growth.

The loss of Brennecke, who sources said played a key role in sourcing and executing deals, comes as Adamantem navigates a challenging environment for private equity. Elevated inflation, rising interest rates, and economic uncertainty have made it more difficult to buy and sell companies at attractive prices.

Despite the headwinds, dealmakers remain optimistic about the opportunities in the Australian market. The country's stable economy, diverse industries, and stable regulatory environment continue to draw the attention of global private equity firms.

Market Context

The departure of a key dealmaker from Adamantem Capital, a prominent Australian private equity firm, comes amid a busy acquisition spree. This could signal increased competition for talent and deals in the Australian PE market as firms look to deploy capital.

Key Takeaways

1 Talent retention is a critical priority for PE firms, especially during periods of heightened investment activity when experienced dealmakers are in high demand.
2 Adamantem's ability to successfully execute on its acquisition strategy may face challenges without the leadership of this key dealmaker, potentially impacting the firm's deal pipeline and investment thesis.
3 The Australian PE market remains highly competitive, with firms vying for a limited pool of attractive investment opportunities. Retaining top talent is crucial for maintaining a firm's competitive edge.

What to Watch

The Australian PE market is likely to remain active, with firms continuing to pursue consolidation and growth opportunities, underscoring the importance of talent management and disciplined deal execution.
