Costar Group Completes Acquisition of UK Portal OnTheMarket.com

LONDON, UK – 12 December 2023 - CoStar Group, Inc., the leading provider of commercial real estate information, analytics and online marketplaces, announces the completion of its acquisition of OnTheMarket plc (OTM), one of the UK’s three most visited residential property portals.

On 19 October 2023, CoStar Group announced a recommended cash offer of 110 pence per share for OnTheMarket Plc, valuing OnTheMarket at approximately £99 million, to be implemented by a scheme of arrangement. The shareholders’ meetings to vote on the scheme were held on 4 December 2023 and the scheme was approved by over 94% in number and over 97% in value of OnTheMarket shareholders voting, representing a record-breaking turnout for OnTheMarket shareholders. The failed efforts of a fringe objector without any standing were soundly rejected by shareholders, employees, and the court. A court hearing to sanction the scheme was held on 7 December 2023 and the Scheme Court Order became effective today.

CoStar Group’s acquisition of OnTheMarket will combine the financial strength, online marketplace experience, and technology of CoStar Group with OnTheMarket’s large network of agents to create a genuine disruptor to the established U.K. market leaders. The recommended acquisition was overwhelmingly supported by OnTheMarket shareholders, the majority of whom were agents.

Andy Florance, Founder and Chief Executive Officer of CoStar Group said: “Today’s announcement gives us the opportunity to combine a leading UK agent friendly site with our technology, expertise, and capital to raise the game for online home shopping in the UK. The current market leader has grown complacent focusing on margin over innovation, and pricing ahead of value. The level of shareholder support we received is a major endorsement of our plans to invest in OnTheMarket.

“CoStar Group has been transforming the world’s real estate through digitization for over three decades. We are relentlessly focused on empowering our customers, delivering this through strong growth in our portals, as well as our data & information businesses. As we digitize the sector and continue to enhance the experience of all those we work with, we are also focused on our investments into Europe, a market that is moving very quickly. Our OnTheMarket acquisition sits firmly within this strategy, and we will bring all our experience to bear as we take OnTheMarket to new levels of success while keeping costs to advertisers at a sustainable level.”

CoStar Group plans to integrate OnTheMarket into its network of real estate marketplaces and anticipates investing £46.5 million into sales and marketing in the first full year following the commencement of the integration, six times the current annual media spend and more than three times the current annual media spend of Rightmove plc. CoStar Group’s initial planned investment will mark the first stage of a multi-year investment programme totalling hundreds of millions of pounds to drive more consumers to the OnTheMarket portal with the goal of significantly increasing the quantity of valuable leads to OnTheMarket’s agent clients.

Jason Tebb, CEO of OnTheMarket, said: “We are very excited to be joining CoStar Group, in a move which will see our business gain the backing of a proven product and technology market leader. We look forward to working together to accelerate our strategy, with the clear goal of becoming the market leader. To do so with a partner who shares our commitment to a fair and sustainable pricing model constitutes a huge step forward for our company”.
