Macquarie Capital Principal Finance, the principal investment division of Macquarie Group, has made a financial commitment to Brennan, though specific figures remain undisclosed.
According to company data, Brennan has demonstrated consistent expansion with average annual revenue growth of 21.5% across nearly three decades of operation, building a workforce that now exceeds 1,000 employees.
Dave Stevens, founder and managing director who continues to lead the organisation while maintaining majority ownership, characterised the deal as a pivotal moment in the company’s development that 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,” he said.
“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.”
Brennan board chair Brendon Cook described Macquarie’s backing as a “transformative step” for the business.
“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.”
“Macquarie’s support will allow us to scale at an even faster rate, further integrating secure AI- driven solutions that will empower our customers,” he said.
Investment comes during active period for Brennan.
Throughout 2025, the company acquired Canberra-based CBR Cyber, expanded its Western Australian presence, and formed new partnerships with TasPorts and LogicMonitor.
It also secured a multi-year agreement with the National Capital Authority, appointed Peter Soulsby as director of cybersecurity, and hired three additional professionals.
While the size of the investment has not been disclosed, the financial commitment from Macquarie Capital Principal Finance underscores growing confidence in Brennan’s growth strategy and long-term market position.
