What is Euronext Access?

Euronext Access is a Multilateral Trading Facility (MTF) operated by Euronext, designed for companies whose market capitalisation is generally below €100 million. It is not a regulated market in the sense of the MiFID II directive, but an organised market with less demanding rules.

It was launched in 2017 during the reorganisation of the Euronext markets, replacing the former Alternext (for the most accessible segment). The aim was to create a progressive ladder: Euronext Access → Euronext Growth → the main regulated market.

In 2022, Euronext introduced Euronext Access+, an intermediate tier with enhanced transparency commitments, for Euronext Access companies wishing to reassure investors without yet taking the step up to Euronext Growth.

Admission requirements on Euronext Access

The requirements are deliberately minimal to allow as many companies as possible to access the capital markets:

Euronext Access+: This premium tier of Euronext Access voluntarily commits to publishing half-year results (vs annual on standard Access), to having a Listing Sponsor, and to disclosing more detailed financial information. It lets companies signal their seriousness to investors without the full constraints of Euronext Growth.

Risks specific to Euronext Access

💧
Low liquidity
Some stocks have days with no trades at all. Selling a position can take several days, sometimes at a price very different from the last quoted price.
📋
Limited financial information
Annual reporting only (standard Access) leaves long stretches with no official financial news. It is harder to track how the company is doing.
📊
Wide bid/ask spreads
The gap between the buy and sell price can be 2 to 5% on the least liquid stocks — an implicit cost that is often underestimated.
🏢
Less governance oversight
No permanent Listing Sponsor and no strict governance constraints. The investor has to assess the quality of management and the shareholder base themselves.

Euronext Access and the PEA-PME

The vast majority of Euronext Access stocks are eligible for the PEA-PME, the tax-advantaged French equity savings plan dedicated to SMEs and mid-caps. After 5 years of holding, capital gains are exempt from income tax (only the 17.2% social levies remain due). Investors in other European countries should check the equivalent wrapper in their own jurisdiction.

PEA-PME eligibility conditions for the listed company:

Given the very small size of Euronext Access companies, these criteria are almost always met. Nonetheless, check eligibility stock by stock with your broker before any investment.

Frequently asked questions about Euronext Access

Euronext Access is the most accessible market in the Euronext family, aimed at very small European companies (micro-caps). It is a Multilateral Trading Facility (MTF), with very light admission requirements: no minimum capital, no mandatory minimum free float, a simplified admission document. It replaced the former Alternext in 2017.
Euronext Access has even lighter requirements than Euronext Growth: no minimum free float (vs €2.5M on Growth), an optional Listing Sponsor (vs mandatory on Growth), annual reporting only (vs half-yearly). In return, liquidity is generally lower and financial transparency less standardised.
Yes, the vast majority of Euronext Access stocks are eligible for the French PEA-PME. The criteria relate to the size of the listed company (fewer than 5,000 employees, revenue < €1.5bn, balance sheet < €2bn) and not to the listing market. Given the very small caps typical of Euronext Access, these thresholds are almost always met.
Euronext Access+ is a voluntary intermediate tier within Euronext Access, launched in 2022. Access+ companies commit to publishing half-year results, to having a Listing Sponsor, and to providing more information to investors — without migrating to Euronext Growth. It is a transparency signal valued by some institutional investors.
