London Stock Exchange’s AIM celebrates 20th anniversary

  • London Stock Exchange’s world leading growth market, AIM, celebrates twentieth anniversary
  • Over 3,600 companies have joined AIM since its inception, raising £92 billion
  • Research highlights AIM’s economic impact on the UK, equivalent to £25 billion in GDP per annum and 731,000 in UK jobs

London Stock Exchange this month celebrates 20 years since the launch of AIM, the world’s most successful and established market for growth companies. Since June 1995, over 3,600 UK and international companies have joined AIM, raising £92 billion through new and further issues.

Grant Thornton’s recent research highlights AIM’s impact over the past 20 years, notably AIM’s ongoing annual contribution to the UK economy, equivalent to £25 billion in GDP. Additionally, the report shows that the public equity market for growth companies has a far-reaching impact on the economy as a whole, including  generating  almost three quarters of a million jobs in Britain alone. 

To celebrate the occasion Rt Hon Greg Hands MP, Chief Secretary to the Treasury and Xavier Rolet, CEO, LSEG opened trading this morning at London Stock Exchange. The event was attended by CEOs of AIM companies, as well as members of the broader AIM community of nominated advisors, investors, brokers, market-makers and liquidity providers and other supporters. This morning the annual AIM conference will feature a keynote speech from Chris Leslie MP, Shadow Chancellor.

Xavier Rolet, CEO, London Stock Exchange Group:
“Over 3,600 companies have joined AIM in the last 20 years. Central to innovation, job creation and productivity, these companies have played a unique role in fuelling economic prosperity in the UK, a dynamic recognised by government, business and investors.

“AIM is a great British success story and today, it is the most successful market for ambitious growth companies in the world. Two decades after it was established, the diverse community that supports these businesses, have helped to make the market a vibrant and thriving one. Recent research overwhelmingly supports the value of AIM to our society, and we are looking forward to continuing to work with the global AIM community on the market’s development in the years to come”

Rt Hon Greg Hands MP, Chief Secretary to the Treasury:
“Britain’s innovative and dynamic SMEs are the backbone of our economy, which is why I’m delighted to celebrate twenty years of AIM, London Stock Exchange’s stock market for smaller companies.

“AIM and London Stock Exchange have provided an active and thriving market for a vast number of high growth SMEs, significantly contributing to the wider UK economy. That’s why this Government has supported AIM by removing Stamp Duty on the purchase of shares on growth markets and allowing AIM shares to be held in ISAs.”

  • AIM was launched with 10 companies, with an aggregate value of £82 million, on 19 June 1995
