Under Rothermere's leadership, DMGT embraced digital transformation. The launch of Mail Online in 2003 proved particularly successful, with the website growing to become one of the world's most-visited English-language news sites. By the late 2010s, Mail Online was attracting significant global traffic, representing a strategic counterbalance to declining newspaper readership.
Beginning in the 2010s, DMGT pursued a strategy of divesting non-core businesses to concentrate on consumer media. The company sold interests in various divisions including Hobsons, Genscape, and Zoopla, collectively raising approximately £1.2 billion. In September 2021, DMGT completed the sale of its insurance intelligence division, Risk Management Solutions (RMS), for £1.4 billion, marking a major restructuring of the group.
In the consumer media sphere, DMGT made strategic acquisitions including the i newspaper in 2019 for £49.6 million and New Scientist magazine in 2021 for £70 million, consolidating its position in quality publishing.
In July 2021, Rothermere announced his intention to take DMGT private through his family investment vehicle, Rothermere Continuation Limited (RCL). The proposal, contingent on the sale of RMS and the listing of online car retailer Cazoo (in which DMGT held a 20% stake), offered 251 pence per share initially, later increased to 270 pence per share.
The offer also included a special dividend of 568 pence per share from the RMS sale proceeds and Cazoo shares, bringing the total value to approximately 1,278 pence per share—representing a 21% premium on the pre-announcement share price. The deal valued the company at approximately £850 million in cash terms, though the total package to shareholders exceeded £3 billion including the special dividend.
Some minority shareholders criticized the offer as undervaluing the company, citing information asymmetry between family and non-family shareholders. However, Nick Train of Lindsell Train, the largest non-family shareholder with approximately 13% of DMGT, publicly supported the bid, describing the company as "clearly very undervalued by other investors".
The privatisation received approval from shareholders in December 2021. As part of the transaction, Rothermere agreed to inject £412 million into the company's pension schemes. DMGT was formally delisted from the London Stock Exchange in January 2022, ending 90 years of public trading since its initial listing in 1932.
Rothermere stated that privatisation would provide strategic flexibility and allow the company to focus on long-term value creation.
Following the completion of the privatisation, Rothermere briefly assumed the role of chief executive of dmg media (DMGT's consumer media division) in addition to his chairmanship. In March 2023, Tim Collier was appointed CEO of DMGT, allowing Rothermere to focus on broader strategic oversight.
In 2023, Rothermere's eldest son, Vere Richard Jonathan Harold Harmsworth, who had joined the company in 2020, was appointed Director of Publishing Strategy for dmg media, continuing the family tradition of involvement in the business.
