Informa itself was created in 1998 by the merger of IBC Group plc and LLP Group plc.[3] Since then Informa has expanded considerably, including a 2004 merger with the publishing company Taylor & Francis and a 2005 acquisition of IIR Holdings, a human capital development company, for £768 million.[4][5] In October 2006, the company was approached by Springer Science and Business Media in a takeover bid,[6] but in early November the Informa board rejected the 630p per share offer as too low.[7]
In early 2007, chairman Richard Hooper announced his retirement in May and, after consulting with major shareholders, the company moved chief executive Peter Rigby to chairman, and managing director David Gilbertson to Rigby's former post. Informa explained Rigby's move by the need to maintain management stability, although it generated some controversy because it did not follow the advice of the UK's Combined Code on Corporate Governance.[4][8]
On 8 June 2008, The Sunday Telegraph revealed that United Business Media (UBM) had proposed a merger with Informa to create a media group worth over £3 billion.[9] The talks were confirmed by Informa in a press release that same day, but described as "preliminary".[10][11] Previously on 13 May The Times had reported that the Carlyle Group and Apax Partners were considering bidding for the company.[12] On 17 June talks with UBM ended because of the rapid rise in Informa's stock price after the public disclosure of the potential merger.[13] On 26 June a private equity consortium consisting of Providence Equity Partners, the Carlyle Group and Hellman & Friedman proposed a takeover bid offering 506 pence per share.[14]
In May 2009 the company announced that it would restructure its business to be incorporated in Jersey but tax resident in Switzerland.[15]
The discontinued domain Informaworld provided subscribers with more than half a million journal articles and 13,000 e-books from all its imprints.[16] In June 2011 the journals and e-books transferred to a new website, Taylor & Francis Online. Abstracting and indexing databases and bibliographic databases were to move from Informaworld to Taylor & Francis Online at a later date.[17]
In July 2013, the company announced that Peter Rigby would retire at the end of 2013 to be replaced as CEO by Stephen Carter.[18] Also in 2013, Informa acquired the Canadian company Hobby Star Marketing, who ran the Fan Expo Canada and Toronto Comiconcomic book conventions. Informa has since acquired other conventions and placed them under the auspices of their Fan Expo HQ brand, including Dallas Comic Con and MegaCon.[19][20][21]
In December 2013, Informa acquired the assets of Elsevier Business Intelligence (EBI) from Reed Elsevier. The EBI business unit includes such publications as The Pink Sheet, The Gray Sheet, IN VIVO, Start-Up, and the Strategic Transactions database along with a series of notable conferences. The EBI assets combined with Scrip, Datamonitor and several other publications formed the newly created Pharma Intelligence division of Informa Business Information.[22]
In January 2014, Carter became CEO of Informa plc.[23] In September 2017, Informa announced that it would be acquiring Dove Medical Press.[24]
In January 2018, Informa announced its intent to acquire UBM plc as part of its strategy to expand in North America and Asia.[25][26][27] The transaction was completed in June 2018.[28]
In 2019, Informa sold the former UBM Life Sciences to MJH Associates.[29] Later in 2019, Informa traded it Agriculture Intelligence unit to IHS Markit in exchange for most of IHS Markit's Technology, Media and Telecoms division.[30] Also in 2019, Informa sold the former Penton design & engineering, manufacturing, energy, buildings, and commercial vehicle divisions, and the former UBM Automotive, to Endeavor Business Media.[31]
In February 2020, Informa launched Omdia by consolidating its portfolio of market analyst companies, Ovum Ltd, Heavy Reading, Tractica, and the majority of IHS Markit's technology, media and telecommunications research business, into a unified brand. The combined research offering includes more than 400 analysts and consultants covering 150 technology markets. Collectively, Omdia issues over 3,000 research reports annually.[32]
In February 2022, Informa sold its Informa Pharma Intelligence unit to investment fund, Warburg Pincus for $2.6 billion.[33]
In January 2024, Informa announced that it would merge the digital business of Informa Tech with TechTarget. The resulting company would keep the TechTarget name with Informa holding 57% stake and the existing TechTarget shareholders holding 43% stake in the merged TechTarget.[38][39] The merger was completed with the business became Informa TechTarget in December 2024.[40]
