It will retain up to a maximum of £5.5m of its cash reserves at deal completion and these net proceeds will be returned to Purplebricks shareholders following transaction costs, a stock market update said.
Purplebricks said this deal was the only one which had the certainty of funding and necessary speed of delivery and was supported by all its directors as well as major backer Axel Springer.
The proposed deal and plans to delist post-completion are still subject to shareholder approval.
Most of the company's board, other than chief financial officer Dominique Highfield who will remain as chief financial officer for a transitional period, have said they will step down.
All other employees will transfer to Strike, however it is anticipated that there will be reductions in headcount in the short term “as part of a wider cost reduction in the business, which are expected to impact on the size of the field teams and certain central functions,” the update said.
Following cancellation of the shares on the Alternative Investment Market, Purplebricks proposes to re-register as a private company, changing its name to Bricks Newco Limited.
Paul Pindar, current chairman of Purplebricks, said this was the best option for shareholders after other routes were considered.
He addd: “I am disappointed with the financial value outcome, both as a 5% Shareholder myself and for Shareholders who have supported the company under my and the board's stewardship.
“However, there was no other proposal or offer which provided a better return for shareholders, with the same certainty of funding and speed of delivery necessary to provide the stability the company needs.”
Marston defended her record, adding: "When I became chief executive 12 months ago, my focus was a wholesale raising of standards within the business and to chart a course towards positive cash generation.
“This included delivering £21m of cost savings, stabilising lettings, new revenue streams, raising our prices and much improved financial transparency and control.
“We have achieved many of these goals, but my view and that of the board in February was that we would be better placed to realise our full potential under private ownership.
“However, the strategic review and formal sale process created increased uncertainty in the business resulting in a need to draw this process to conclusion, which has also been accentuated by the timing of expiry of our relationship which lets us provide pay later solution.
“Taking the actions we did has allowed us to secure a solvent outcome, which protects the future of the business and the Purplebricks consumer driven brand, alongside the benefits of further investment. It has been a challenging and uncertain time but the passion and commitment of our people has been tremendous and I sincerely wish everyone the very best for the future."
Sir Charles Dunstone, partner at Strike backer Freston Ventures, said: "We remain committed to the online model, which offers customers a much better experience at a far lower cost.
“This is a positive outcome for anyone looking to sell their home and save money doing so. Purplebricks has dramatically changed the industry by driving down the cost of estate agency and we aim to combine its significant brand recognition with an even more disruptive business model.
In bringing together the two brands, we will supercharge
“Strike's mission to democratise house selling by empowering customers to have more control over a process that has barely changed for 200 years.
“At Freston Ventures we are focused on building household brands that are trusted by consumers across the UK. We believe there is a better way to sell your house and through this deal, we are developing the market-leading brand to deliver it."
