The London Stock Exchange is undertaking one of the most meaningful reviews of the AIM listed rules in years. The consultation paper AIM Notice 62 was published on 4 June 2026 and sets out the proposed developments. All are designed to make AIM simpler, more flexible, and more attractive to growth companies at a time when listings and retention are under pressure.
There’s only a short window for CFOs to assess the impact and feed into the consultation which include AIM tax changes. The consultation closes on 2 July 2026.
If you’re a CFO of an AIM-listed business, or considering a listing, this isn’t just regulatory noise. These proposals could reshape how you fund growth, execute deals, and communicate with investors. We’ve taken a look at this latest AIM notice and here’s what you need to know. And why it matters now.
The direction of travel: less friction, more flexibility
At its core, the Exchange is trying to remove barriers that don’t add value while strengthening AIM’s position as a global growth market.
It’s about streamlining the admission process and making fundraising faster and more controlled. Reducing unnecessary deal complexity. Giving founders and boards more freedom. Thereby reinforcing AIM’s investor-driven model.
For CFOs, that translates to one thing: more control over how you access and use capital.
Admission: lowering the cost of entry and re-thinking disclosures
One of the headline changes proposed is removing the requirement for a formal working capital statement in admission documents.
In its place, companies would provide clear, tailored disclosures on liquidity, funding position, and expected capital needs.
This removes a costly and time-consuming process. But it shifts the burden to you to clearly articulate your financial position in a way investors trust.
UK GAAP back on the table
Under the proposals UK-incorporated AIM companies will be able to use UK GAAP (FRS 102) instead of IFRS.
This would mean lower reporting complexity, reduced conversion costs and ultimately more flexibility for scaling businesses.
Shorter, sharper documents
Companies will be able to incorporate information by reference, rather than repeating it. This should mean leaner admission documents with more emphasis on clarity over volume.
Fundraising: more control when it matters most
Introducing the “Capital Access Window”
AIM companies would be able to request a temporary suspension during a fundraising round. This is a positive move in that it would mean less market leakage which in turn means less volatility around share price. Which will give you greater ability to approach a wider investor base.
All of which gives you more control over timing, messaging, and execution especially in complex or sensitive fundraises.
Deals and M&A: fewer unnecessary roadblocks
The Exchange is tackling a long-standing issue: transactions being treated as reverse takeovers purely because of size. The proposals take a more commercial approach.
Deals won’t trigger “reverse takeover” treatment unless they fundamentally change the business. And the “substantial transaction” threshold will rise from 10% to 25%
This is a clear move towards substance over form as it should mean fewer disruptive suspensions, less of a burden when it comes to documentation and gives you more freedom to execute your business growth strategy.
Founder-led businesses: more flexibility, less compromise
AIM is positioning itself more clearly as a market for entrepreneurial, high-growth companies. There are AIM tax changes proposed which mean more flexibility to align governance and incentives with long-term growth but expect more scrutiny from investors:
- Dual-class shares allowed
- Founders can retain control through special voting share structures at IPO.
- Greater freedom on pay structures
- Less regulatory friction on non-standard director remuneration, provided protections are in place.
Governance: a shift away from “tick-box” compliance
The proposed changes signal a move away from rigid governance frameworks. There’s a greater focus on clear, meaningful disclosure across key areas like board structure, risk, and investor engagement rather than compliance with a governance code.
There’s also a new ability proposed to:
- Voluntarily disclose engagement with proxy advisers
- Respond directly to misleading third-party commentary
This doesn’t mean that the requirement for governance is disappearing. It becomes more judgement-led and narrative-driven. Investor communication becomes even more critical.
International growth: opening the door wider
AIM is also looking outward with a new “Express Market” route for admission. There’ll be a new fast-track admission route for companies already listed on recognised international exchanges.
These does mean there could be more international competition between AIM listed companies but also the potential for more cross-border growth and capital access.
Should you engage with the consultation?
The consultation runs until 2 July 2026, and this is a genuine opportunity to influence how AIM evolves. It’s worth considering how the proposed changes affect your funding strategy. The potential impact on your transaction pipeline. Whether your current reporting and governance approach would stand up to a more principles-based regime.
This is your opportunity to have your say on the AIM rules. The opportunity may not arise again anytime soon.
Final thought: AIM is redefining its edge
These reforms aren’t about making AIM “lighter touch” for the sake of it. They’re about making it more relevant, globally competitive and fit for modern growth businesses. Whilst it should give CFOs more flexibility and great influence there is also an implied challenge. CFOs will need to lead with clarity, credibility, and commercial insight.
