Highlights:
- Speculation around inheritance tax relief for AIM shares has caused valuations to diverge from larger UK indices.
- Panmure Liberum warns of potential cost-of-capital impacts on UK growth-focused firms if tax relief changes.
- AIM 100 share prices show greater declines than other UK indices, reflecting current uncertainty.
Speculation about the future of inheritance tax (IHT) relief for shares on London’s AIM market has led to marked fluctuations in the valuations of smaller firms, separating them from the broader UK indices, according to Panmure Liberum’s head of research, Simon French. French notes that stocks in several AIM-listed companies, including CVS Group (AIM:CVSG) PLC, Next 15 Group PLC (AIM:NFG), Revolution Beauty Group PLC (AIM:REVB), and Artisanal Spirits Company PLC (AIM:ART), have seen valuation shifts due to revenue-raising proposals suggested by outside think tanks ahead of the Autumn Budget. The proposals have yet to be addressed by policymakers, but industry observers are concerned about potential changes that could impact investor behavior.
Key Drivers Behind the Speculation
This valuation shift comes as investors weigh the implications of potential changes to tax relief for AIM-listed shares held for over two years. AIM shares are often eligible for inheritance tax relief, a policy French views as central to the UK’s growth capital ecosystem. He stresses that the policy’s role has become more significant post-Brexit, as investors shifted away from broader UK equity ownership toward growth-focused UK-listed firms.
While no government ministers have issued statements directly addressing the speculation, French points to ongoing reviews of various tax policies as part of a comprehensive government approach to potential tax revenue adjustments. This tax discussion reflects wider fiscal considerations ahead of the Autumn Budget. Given that inheritance tax is one of several areas under review, Panmure Liberum issued a note to clients detailing ways to navigate this period of heightened volatility on AIM and outlining recommended AIM-listed, ‘buy’-rated stocks.
Potential Impact on UK Growth-Focused Firms
French argues that removing IHT relief from AIM-listed shares could challenge UK companies by raising the cost of capital, thereby weakening government goals for economic growth. He also notes that the AIM market plays a unique role in funding smaller companies seeking growth capital. The absence of tax relief, he argues, could diminish AIM’s appeal to investors seeking tax-efficient growth investments, ultimately slowing the expansion of firms reliant on growth capital.
Data supports his concerns, showing AIM 100 companies facing greater share price declines than the FTSE 100, FTSE 250, and FTSE Small Cap indices since the last general election. Panmure Liberum reports that 62% of AIM 100 companies have seen share price declines over the period, with an average decrease of 5.2% since July 4. This compares to flat performance for the FTSE 250 and Small Cap averages and a 3.9% increase for the FTSE 100. French suggests this discrepancy underscores the sensitivity of AIM-listed companies to uncertainty surrounding IHT relief.
Broader Market Context and Future Prospects
As investors await the Autumn Budget, there is a shared anticipation that the government will clarify its stance on IHT and other forms of business relief that could affect AIM-listed companies. For now, Panmure Liberum remains cautious but optimistic about the AIM market, recommending a selection of stocks that may be resilient in the face of these uncertainties. With AIM valuations under pressure, French’s analysis emphasizes the importance of understanding the role tax incentives play in supporting growth and innovation among UK-listed companies.
