A share in an Austrian GmbH is the most common acquisition unit in the local mid-market. Whether the buyer takes over 25 percent from a departing co-shareholder or 100 percent of all shares as a classic share deal: the legal mechanics differ fundamentally from a sale of shares in a listed company or a sale of assets. The GmbH share is not a freely tradeable security but a right that needs to be shaped.

This post explains how GmbH shares are bought and sold in Austria. The focus is on the requirement of a notarial deed under the GmbHG, on the entry in the company register, on typical transfer restrictions and on pre-emption and call rights. It also covers when a majority shareholder has to bring along co-shareholders and how the handover of management is cleanly organised.

From a lawyer perspective the careful preparation of the notarial deed decides whether a share purchase can be completed in a single sitting. Whoever reviews the articles of association in advance and secures the funding avoids the most common pitfalls. How the transfer fits into the broader picture of a company acquisition is shown by the focus page on share deal and asset deal.

Classify your share purchase

Is your GmbH share purchase ready for completion?

Answer one or two questions on the articles of association and on the funding. You receive an initial classification of whether the notarial deed can be scheduled.

01 Question 1

Have you reviewed the articles of association of the target GmbH for transfer restrictions and pre-emption rights?

Many Austrian GmbH constitutions tie a share transfer to the consent of the co-shareholders or grant pre-emption and call rights. Overlooking these clauses can block closing.

All paths at a glance

Overview of all answers.

01

Without inspection of the articles of association the transferability of the share cannot be assessed.

A share in an Austrian GmbH is not freely tradeable like a listed security. Transfer restrictions, pre-emption rights and call rights are anchored in many constitutions. Before binding commitments are made the current articles of association together with any shareholders agreement must be reviewed.

If consent requirements result, the necessary resolutions or waivers should be planned well before the notarial appointment. The focus page on share deal and asset deal offers more depth.

02

The conditions for the notarial deed are in place, now the careful drafting matters.

Where articles, funding and handover date are clear, the notarial deed can be prepared. Pay attention to the correct description of the share, to the confirmation that the share capital is fully paid in and to the list of shareholder resolutions that have to be passed at the same time.

After signature the change of shareholders is filed with the company register. How the related contract is built is shown in the post on the share transfer agreement, notarial deed and company register.

03

The conditions for the notarial deed are not yet complete.

A notarial appointment without secured funding usually is postponed or falls through. Sort out the financing structure first, whether from own resources, a bank commitment or a vendor loan. Only when the funds are bindingly available is it worth scheduling the notarial appointment.

In parallel a handover plan should be in place: when do management, bank accounts, keys and IT access pass to the buyer? An initial assessment of the risks of your project is provided by our M&A transaction risk profile.

The share as the object of acquisition

Unlike a share in a stock corporation, the share in an Austrian GmbH is not a security. It arises with the assumption of a share in the capital and is documented in the articles of association and in the list of shareholders. Each shareholder holds exactly one share per capital contribution. Whoever subscribes for several tranches still holds a single share in the corresponding amount.

This particular feature shapes the sale. What is transferred is not a bundled security but a right defined by statute and by contract. The transfer takes place by assignment. Whoever sells only part of the share must first split it in the extent of the capital portion to be transferred. On a split the minimum capital requirements of the GmbHG must be observed.

With the acquisition the buyer enters the position of a shareholder. It receives voting rights, profit participation and information rights. It also takes on any outstanding payment obligations on capital that has not been fully paid in. The basic concept is explained in the glossary entry on the transfer of shares.

Transfer restrictions, pre-emption rights and call rights

Many Austrian GmbH constitutions contain transfer restrictions. They tie the effective assignment to the consent of the general meeting or of individual shareholders. Without that consent the assignment contract is effective between seller and buyer, but it has no effect vis-a-vis the company. Before every share purchase the current articles of association belong in the review.

Often pre-emption or call rights are added. A pre-emption right gives the other shareholders the option to step into the agreed purchase price. A call right allows the remaining shareholders to acquire the share themselves at a price defined in the constitution. Both clauses delay a sale to third parties and have to be worked through cleanly.

In family-owned and partnership-style companies shareholders agreements are common. They can set additional limits, such as drag-along or tag-along clauses. Whoever overlooks this layer may buy a share whose transfer is blocked later. The focus page on shareholder disputes shows how transfer restrictions can lead to conflicts.

Notarial deed and company register at a glance

The assignment of a GmbH share requires a notarial deed under the GmbHG. Seller and buyer have to draw up the assignment agreement before an Austrian notary in this form. Without a notarial deed the assignment is formally void. At the appointment the transfer process, the purchase price and all ancillary arrangements are bindingly recorded.

After execution the managing directors file the change of shareholders with the company register. The entry has declaratory effect: it makes the change visible in the register, but it is not a precondition for the effectiveness of the assignment itself. Only the entry, however, creates publicity vis-a-vis third parties. Further depth on the mechanics is given by the post on share transfer agreement, notarial deed and company register.

In parallel further steps need to be organised: the removal and reappointment of the management, the deposit of the specimen signature, the filing with the register of beneficial owners and, where applicable, an amendment of the articles of association. The concept of the company register is explained in the glossary.

The central checkpoints

What matters when buying and selling GmbH shares

These points decide whether a share purchase runs smoothly. Review each one before scheduling the notarial deed.

Checkpoints when buying and selling GmbH shares with recommended approach and typical risk
Checkpoint Recommended Typical risk
Articles of association Current version reviewed Transfer restrictions and call rights known Hidden consent requirements
Share capital Payment status clarified Confirmation that capital is fully paid in Outstanding capital passes to the buyer
Form Notarial deed prepared Execution before an Austrian notary Plain written form is invalid
Management Change cleanly organised Removal and reappointment documented Vacancy or double appointment
Company register Filing submitted promptly Change publicised and beneficial owners updated Old data remain visible

The listed parameters are usual building blocks, not fixed requirements. The content and scope of preparation depend on the specific articles of association and on the size of the transaction.

Caution on a partial share transfer: Whoever sells only part of a share must first split the underlying capital portion. The minimum requirements of the GmbHG are mandatory. The transfer of capital that has not yet been paid in should also be expressly addressed. Booking an initial consultation (72 euro) can quickly bring clarity.

Handover of management and liability points

With the assignment only the shareholder changes, not automatically the management. In most sales, however, the removal of the previous managing director and the appointment of a new one by the buyer follow immediately. The related resolutions are ideally recorded at the notary at the same time. Afterwards bank accounts, powers of attorney, IT access and official correspondence are switched to the new management.

From a liability angle the former shareholder is, in principle, no longer exposed to the obligations of the company, provided no personal security is in place. Personal guarantees, letters of comfort or pledges have to be released separately. Otherwise the seller economically continues to pay for a business it no longer owns.

On the tax side the transition is felt as well. Profit distributions reach the buyer from the agreed reference date, while the seller may realise a capital gain. How the purchase price itself is adjusted post-closing is shown in the post on the purchase price adjustment.

Frequent questions

Buying and selling GmbH shares.

Is a written contract enough to assign a GmbH share? +

No. The assignment of a GmbH share requires a notarial deed in Austria. Plain written form is not sufficient and leads to a formal nullity of the assignment. Pre-contractual arrangements such as a term sheet or a letter of intent can be made in writing, but the actual assignment must be executed before a notary.

What does a transfer restriction in the articles of association mean? +

A transfer restriction makes the effectiveness of an assignment vis-a-vis the company dependent on the consent of the general meeting or of certain shareholders. Without that consent the buyer cannot exercise its rights against the company. Before every purchase the articles must be reviewed for this restriction and the necessary consent obtained in time.

When does the buyer formally become a shareholder? +

The buyer becomes a shareholder once the notarial deed takes effect and any transfer restrictions are satisfied. The entry in the company register has only declaratory effect and creates publicity vis-a-vis third parties. Internally vis-a-vis the company the notification of the change to the management is usually the decisive act to exercise voting rights and profit participation.
