Brennan set to supercharge next growth phase following an investment by Macquarie Capital Principal Finance.

Sydney, Australia | 18 December 2025

Leading Australian systems integrator, Brennan, is set to supercharge its next phase of growth through acquisition and organic expansion following an investment by Macquarie Group’s principal investment arm, Macquarie Capital Principal Finance.

Macquarie’s investment represents a significant milestone for Brennan, a business that has grown its revenue at an average of 21.5 per cent per annum over its 28 years of operations and with over 1,000 team members. Through its customer connected approach, Brennan has achieved an industry leading Net Promoter Score of more than 80 and a retention rate of more than 95 per cent.

Founder and Managing Director of Brennan, Dave Stevens, who remains at the helm of the business and the majority shareholder, said the investment marked a major milestone in the evolution of Brennan and would reinforce its position as Australia’s largest sovereign systems integrator.

“Through Macquarie’s support, we expect to continue our focused growth trajectory by making significant strategic acquisitions and continuing our investment in cutting-edge sovereign capabilities in AI, automation and cybersecurity.”

“As well as improving our ability to bid for and win large Australian government and private sector contracts, Macquarie’s involvement also provides us with the opportunity to explore international growth opportunities, meaning we could finally see Australia compete on the global systems integrator stage.

“We’re excited about what’s ahead and look forward to working with Macquarie to unlock new opportunities while staying true to the values and approach that have defined us for nearly three decades.”

Chair of Brennan’s Board of Directors, Brendon Cook, said Macquarie’s investment was a transformative step for Brennan, which has successfully evolved from a managed service provider to Australia’s leading sovereign systems Integrator.

“It not only strengthens the company’s balance sheet but is also important for our vision and growth strategy which we will continue to deliver on with the commitment and leadership that has shaped Brennan’s success to date.”
