SAS: how to successfully increase capital?

Updated March 2026 - The capital increase in SAS is a strategic operation. It can be used to finance growth, bring in an investor, recapitalize the company or rebalance the financial structure. But in the field, errors almost always come from the same points: poor calibration of the dilution, forgotten formalities and confusion between contribution in cash, contribution in kind and incorporation of reserves.

According to Entreprendre.Service-Public, the capital increase can notably allow:

• ▸to welcome new shareholders;
• ▸to finance future investments;
• ▸to strengthen the credibility of the company;
• ▸to recapitalize in the event of tension on equity.

To place the operation in a broader context, also see our SARL or SAS comparison, our article on the commissioner for contributions to SAS or SARL and our file on the capital reduction not motivated by losses.

1. The cash contribution

Shareholders contribute funds to the company. The sums must be deposited into a dedicated account or with a notary under the conditions provided.

2. Contribution in kind

An asset is contributed to the company: equipment, goodwill, patent, titles, etc. This path requires particular vigilance regarding evaluation. It may involve a contribution commissioner.

3. The incorporation of reserves

The company transforms part of its reserves into capital. It is a useful operation to strengthen the structure without bringing in new cash.

Hayot Expertise Advice: a capital increase is not just a formality. It is an operation of power and valorization. Before launching it, it is necessary to measure the dilution, the possible issue premium and the effects on existing pacts or statutes.

• ▸decision in accordance with the statutes;
• ▸drafting of the minutes;
• ▸updating of statuses;
• ▸legal announcement if required;
• ▸declaration on the formalities counter;
• ▸adequate supporting documents depending on the nature of the operation.

Entreprendre.Service-Public also reminds that the capital increase by contribution in kind must be registered with the SIE within one month of its recognition, while this formality is not required for cash or the incorporation of reserves.

A capital increase often modifies:

• ▸the distribution of voting rights;
• ▸the economic weight of each shareholder;
• ▸entry conditions for new investors;
• ▸sometimes the actual beneficiaries to be declared.

In an SAS, statutory flexibility is a strength, but it requires careful rereading of the approval, exclusion, pre-emption or majority clauses.

A preliminary review is useful if:

• ▸a contribution in kind is envisaged;
• ▸an investor enters into the capital;
• ▸valuation is debated;
• ▸the company wants to recapitalize after difficulties.

We can prepare the legal calendar, review the statutes and coordinate the formalities of your capital increase.
