Management Comments

• "Today marks an important milestone as CoStar Group and Domain officially come together to redefine the Australian property market." Andy Florance, CEO of CoStar Group.
• "For too long, agents, buyers and vendors have faced an unbalanced marketplace dominated by an intention to extract value rather than deliver it. Our vision is different. We are building a more compelling user experience at a lower cost – driving greater value for agents, vendors, and buyers alike. We are the agents ally, and we will never operate at their expense." Andy Florance, CEO of CoStar Group.
• "Agents and vendors are being squeezed by legacy models that raise prices without raising value. That ends here." Andy Florance, CEO of CoStar Group.
• "We dismantled market dominance in the U.S. by transforming Homes.com into a true agent-friendly platform, and we are ready to apply that same proven playbook in Australia." Andy Florance, CEO of CoStar Group.
• "This transaction reinforces the strong fundamentals of Domain and represents compelling value for customers. With CoStar Group, we believe Domain will accelerate its ability to deliver innovative solutions and greater opportunities for customers, while maintaining its trusted place in the Australian property market." Jason Pellegrino, President of Domain.
• "The opportunity in Australia is vast, and our commitment is clear: to deliver more, for less, and to be the partner agents and sellers deserve." Andy Florance, CEO of CoStar Group.
