The Alternative Investment Market (AIM), London’s junior market, marks its 30th anniversary amid significant challenges that underscore a decades-long shift in investment appetite and economic policy. Established in 1995 as a platform for smaller, growth-focused companies to access capital with more flexible listing rules than the main London Stock Exchange (LSE), AIM originally flourished as a vibrant marketplace for entrepreneurs and investors embracing risk. However, its current trajectory paints a sobering picture: the number of companies listed has sharply fallen from its peak of 1,694 in 2007 to just around 650 today, the lowest since 2001.

Marcus Stuttard, AIM’s chief executive, highlighted a deep-rooted change in British investor behaviour over the past decade. Speaking about AIM’s 30 years, he emphasised that the UK economy needs to “embrace risk” to stimulate higher growth, urging a renewed celebration and support of entrepreneurs who innovate and build new companies. Stuttard noted that investors must recognise that seeking superior returns inherently involves accepting the possibility of losses—a mindset that has waned in the UK as investors became increasingly risk-averse, favouring established and fast-growing US tech stocks over smaller, domestic ventures.

This risk aversion coincides with a range of external pressures weighing heavily on AIM. Recent UK government policies, such as the halving of inheritance tax relief on AIM shares announced by Chancellor Rachel Reeves, have further dampened incentives for holding AIM-listed shares, particularly among those seeking tax-efficient wealth transfer. Industry experts like Jason Hollands of Evelyn Partners have criticised this policy shift, noting its contradiction with the government’s stated ‘growth mission’ and its adverse impact on investor enthusiasm.

The decline in AIM-listed companies is not solely due to fiscal policy. Many companies have delisted or been taken over, often citing high costs and regulatory burdens. Data from the British Business Bank and market observers indicate the cost to list on AIM can be around £600,000, with annual maintenance expenses possibly exceeding £500,000, imposing a substantial financial strain on smaller firms. Additionally, stricter corporate governance and administrative demands have accumulated over time, which, although enhancing the quality standards on AIM, have paradoxically made it less attractive compared with alternative financing routes such as private equity or listings on US exchanges where valuations are perceived to be more favourable and capital pools deeper.

The London Stock Exchange has acknowledged these challenges and is contemplating reforms to AIM’s listing rules, aiming to reduce red tape and regulatory costs to rejuvenate the market. Industry figures argue that easing reporting requirements and corporate governance burdens could make AIM more competitive and accessible once again, potentially reversing the shrinking pipeline of initial public offerings (IPOs). Recent years have seen the lowest number of IPOs since the global financial crisis, with only a handful of new entrants competing to list on AIM in 2024.

Despite these setbacks, AIM’s economic contribution remains significant. Though smaller in size than its heyday, the market continues to facilitate capital raising for innovative companies, having helped over 4,000 firms raise approximately £135 billion since inception. In 2023 alone, AIM-listed companies contributed an estimated £68 billion to the UK economy. High-profile success stories, such as Jet2.com, demonstrate the potential for substantial long-term returns from investing in AIM companies, reinforcing the view that smaller companies can outperform over time if given adequate support.

There is growing consensus among market participants and policymakers that reversing AIM’s decline is critical for sustaining a diverse, dynamic UK equity market and fostering home-grown innovation. Suggestions include mandatory pension fund allocations to UK assets, reintroduction or expansion of tax-advantaged savings schemes encouraging retail investment, and more government-led initiatives to cultivate investor confidence. Public participation in stock ownership remains comparatively low in the UK, with fewer than a quarter of households investing directly in equities, contrasted with roughly 60% in the US, indicating scope for cultural and financial shifts that could help rejuvenate markets like AIM.

While AIM’s situation today is far from its peak, its role as a crucible for entrepreneurial growth and investment risk remains vital. Recalibrating incentives and regulatory frameworks to better match the needs of smaller and emerging companies could help AIM reclaim its position as a cornerstone of the UK’s economic fabric, supporting innovation and higher growth rates that the nation’s economy urgently seeks. The next 30 years will test whether AIM can adapt and thrive or continue its steady erosion amid global competition and shifting investor priorities.
