Tag-along and drag-along are clauses that appear in shareholder agreements and sale contracts. Many sellers fear them without understanding them. We explain what they mean, when they protect you and when they constrain you.
When a business owner encounters the terms “tag-along” and “drag-along” in a legal document for the first time, the most common reaction is unease. Not because these mechanisms are necessarily adverse to the seller, but because they arrive in English, in dense legal contexts, and no one takes the time to explain them in plain terms.
That is exactly what this guide aims to do: explain what they are, how they appear in the documents, when they work in your favour, and when they deserve careful attention.
When a company — especially a family business — has more than one shareholder, the interests of the majority and the minority can diverge. The classic problem: the majority shareholder finds a buyer willing to pay a good price for their stake. What happens to the minority? They may be left in a company now controlled by a new majority owner they didn’t choose, with whom they have no relationship and whose objectives may be entirely different from their own.
The reverse also applies: a minority shareholder can have the power to block a sale that would benefit everyone, simply by refusing to sell their stake or demanding an unreasonable price for it.
These two asymmetries are the problems that tag-along and drag-along clauses are designed to resolve.
The tag-along (also called a co-sale right, piggyback right, or derecho de acompañamiento) is a right that protects the minority shareholder. It provides that, if the majority shareholder sells all or part of their stake to a third party, the minority has the right to join the sale on the same terms: same price, same conditions, same buyer.
In other words: no one can be “left behind” with a new owner they did not choose.
In the shareholders’ agreement, tag-along rights typically appear as a specific article under a heading like “Co-Sale Rights” or “Tag-Along”. They define: the ownership threshold that activates the right, the percentage of the minority’s stake they can include in the sale (proportional to the majority’s sale or the full minority stake), the exercise deadline, and the notification procedure.
In the SPA for the sale transaction, tag-along rights may appear as a condition precedent or as a seller warranty that all minority rights have been properly managed.
It benefits you if you are the minority. If an investor acquires 30% of your company, and you agree a tag-along in the shareholder agreement, you have assurance that if that investor later wants to sell their stake to a third party, you can sell yours too on the same terms. It is a valuable protection.
It may complicate things if you are the majority seller. If you have a minority shareholder with tag-along rights and you want to sell your stake, you need the buyer to be willing to acquire the minority’s stake too. This can complicate negotiation and, in some cases, may be an obstacle if the buyer does not want to purchase 100%.
Practical tip: When negotiating the original shareholder agreement, push to limit the minority’s tag-along to sales above a certain threshold (e.g., it only activates if the majority sells more than 50% of their stake), and ensure the tag-along price equals the net price received by the majority with no adjustments.
The drag-along (also called a take-along right or derecho de arrastre) is the right that protects the majority shareholder (or the investors controlling the company). It provides that, if the majority decides to sell the whole business to a third party, they can compel the minority to sell their shares too, on the same terms.
The function is to eliminate the blocking power that the minority would otherwise hold. Without drag-along, a shareholder with 10% of the capital can prevent a sale by demanding a disproportionate price or simply refusing to sell. With drag-along, the majority can force a clean 100% exit.
If you are the majority business owner with minority shareholders (earlier investors, co-founders, management with equity), drag-along in the shareholder agreement is your tool to ensure you can execute the sale on your timeline without minority shareholders blocking it.
Drag-along benefits you as the majority because:
Drag-along may disadvantage you if you are a minority being compelled to sell at terms you find inadequate. This is why, when an investor enters your company and proposes a drag-along, you must negotiate appropriate protections (see below).
In a sale transaction SPA, drag-along may appear in two forms:
As a title warranty. The seller warrants to the buyer that they can transfer 100% of the capital and that no shareholder rights prevent full transfer. If tag-along or drag-along rights exist in the shareholder agreement, the seller must manage their exercise before or simultaneously with closing.
As a future acquisition mechanism. Where the seller can only transfer a partial stake initially and the buyer wants to secure the ability to acquire 100% later, a drag-along may be included in the SPA requiring remaining shareholders to sell if the buyer requests it under agreed conditions.
Imagine you sold 25% of your company to a financial investor three years ago. The investor now wants to exit — they’ve reached the end of their investment period. Two possible situations:
With a well-drafted tag-along in the shareholder agreement: The investor can sell their 25% to a third party, but you have the right to join the sale and sell your 75% to the same buyer, at the same price. This may be exactly what you want if you are also considering an exit.
Without tag-along or with a poorly drafted one: The investor can sell their 25% to someone you don’t know, and you end up with an unfamiliar new co-shareholder alongside whom you must operate the business.
You hold 70% of the company, with two minority shareholders holding 30% between them. A buyer wants to acquire 100%.
With a well-structured drag-along: You can compel the minority shareholders to sell to the buyer on the same terms as you. The transaction closes cleanly.
Without drag-along: You must negotiate separately with each minority shareholder. One may demand more than their proportional share. The other may simply refuse to sell. The buyer may walk away faced with the difficulty of acquiring 100%.
A private equity fund acquires 40% of your company and negotiates a drag-along entitling them to force a sale of the entire business if they have not achieved their exit within five years.
Five years later, the fund wants to sell to the highest bidder. They have an offer of €8M for the business — implying €3.2M for the fund (40%) and €4.8M for you (60%). But you believe the business is worth €12M.
Without protections in the drag-along, the fund can compel you to sell at €8M. That is why, when you signed the original shareholder agreement, you should have negotiated: a minimum price floor below which the drag-along does not activate, or the right to an independent valuation as a price floor.

For drag-along:
Both tag-along and drag-along are clauses that should be formalised in the shareholder agreement before any external investor enters. A company without a formalised shareholder agreement that addresses these rights is exposed to serious conflicts at the time of sale.
If your company does not have a shareholder agreement and you are considering a sale or investor entry, this is the time to draft one. It is not costly in relative terms, but it can save very expensive conflicts later.
