AIM, the London Stock Exchange’s growth market, has turned 30.
Since its birth in 1995, AIM has served as a launchpad for around 4,000 companies, raising £136 billion and supporting hundreds of thousands of jobs.
According to Grant Thornton, AIM-listed firms contributed £68 billion in gross value added to the UK economy in 2023 alone.
Yet despite these achievements, AIM now faces a critical test.
The market is shrinking fast, with 89 companies leaving last year and 71 gone already this year, pushing AIM to its lowest number of listed firms ever, just 679. For AIM to survive and thrive for another 30 years, it must confront and overcome several pressing challenges.
At its core, AIM was designed as a light-touch alternative for growing businesses to access public capital.
Costs, costs and more costs
But over time, compliance and listing costs have ballooned, with many companies facing bills of £500,000 or more annually. Coupled with falling trading liquidity and subdued valuations, this has made AIM less attractive to smaller companies.
Susannah Streeter, head of money and markets at Hargreaves Lansdown, sums up the predicament: “AIM remains one of the most successful markets globally for smaller growth firms, but the number of companies listed has fallen by around 60% since 2007. Without reforms, it risks losing relevance.”
What reforms? To start, AIM must adapt its regulatory framework to be more proportionate and less costly, striking a balance between investor protection and flexibility for emerging businesses.
The introduction of a Corporate Governance Code is a step forward, but more needs to be done to ease the financial and administrative burden on companies.
Confidence
Investor confidence is another cornerstone. Changes to tax incentives, like the halving of Business Property Relief, have sapped appetite for AIM shares among some investors, reducing liquidity further.
Reversing or adapting such measures could encourage more long-term investment in AIM stocks.
Government initiatives offer a glimmer of hope. The Mansion House Accord, signed by 17 pension providers, aims to unlock up to £50 billion in UK investment, with a focus on smaller companies.
Pension “megafunds” could provide a much-needed capital boost for AIM firms, but the scale of this support remains to be seen.
Looking back, AIM has celebrated remarkable success stories, companies like Hiscox, which joined AIM in its early days and is now a FTSE 100 heavyweight, delivering more than 2,600% returns to investors.
Remarkable successes
Wynnstay Properties, with returns exceeding 6,000%, shows the market’s potential to nurture enduring growth.
But for every success, there have been high-profile failures and scandals, from Langbar International’s fictitious deposits to Patisserie Valerie’s collapse, that have dented trust.
Dan Coatsworth, investment analyst at AJ Bell, points out that while AIM’s early years produced winners, “the market now needs to demonstrate it can foster a new generation of growth companies and regain investor trust to secure its future.”
AIM's future also hinges on addressing liquidity and valuation concerns. Reduced liquidity not only affects trading but also depresses company valuations, making it harder for firms to raise fresh capital.
Feedback loop
This feedback loop must be broken to restore vibrancy to AIM.
Joseph Hill of Hargreaves Lansdown highlights that despite recent difficulties, the case for smaller UK companies remains strong. The FTSE Small Cap ex IT index outperformed major indices over five years, signalling underlying potential, he notes.
Investment funds focusing on smaller firms, such as Artemis UK Smaller Companies and Royal London UK Smaller Companies, demonstrate that with the right approach, investors can navigate the risks and find growth opportunities.
Ultimately, AIM stands at a crossroads. It can either continue shrinking, losing relevance to alternative platforms and overseas markets, or it can reinvent itself, through smarter regulation, renewed investor incentives, and fresh capital flows, to reclaim its position as the UK’s premier growth market.
If it succeeds, investors and companies alike may look back on the current troubles as a temporary setback.
When AIM celebrates its 60th birthday in 2055, it could well be a market transformed, still delivering opportunities and growth for generations to come.
