What tag-along means
A tag-along right allows a minority shareholder to join a sale by the majority, on the same terms.
The risk it addresses is specific. A minority shareholder invested because of the people running the company and the arrangements they agreed with them. The majority then sells to somebody else. The minority is left holding the same percentage of the same company, now controlled by a stranger they did not choose, with no market for their shares and no way out.
Tag-along prevents that. Where the majority proposes to sell, the minority can require that their shares be included in the sale at the same price and on the same terms.
It is the mirror image of drag-along. Drag-along compels a minority to sell for the majority's benefit. Tag-along entitles a minority to sell for its own protection.
How it is used
The clause has a few variables that determine how much protection it gives.
The trigger. What sale by the majority activates it: any sale, a sale above a stated percentage, or a sale that transfers control. A trigger set at any transfer is the strongest protection.
Full or proportionate tag. Under a full tag, the minority can sell all of their shares. Under a proportionate tag, they can sell the same proportion of their holding as the majority is selling. Full tag is stronger and is what a minority should seek.
The terms. The minority must receive the same price per share, the same form of consideration and the same conditions.
The procedure. The selling shareholder must give notice of the proposed sale with the terms, and the minority has a defined period to elect to tag.
And the consequence of the buyer refusing. A well drafted clause provides that the majority may not complete the sale unless the buyer also acquires the tagging shares, which is what gives the right teeth.
Key features
- Allows a minority to join a sale by the majority on the same terms
- Protects against being left with an unknown controlling shareholder
- Full tag permits selling the entire holding; proportionate tag only a share
- Requires notice of the proposed sale and an election period
- The majority cannot complete unless the buyer takes the tagging shares
- The mirror image of drag-along
How this works in Nigeria
For anybody taking a minority stake in a Nigerian private company, tag-along is among the most valuable provisions to negotiate, and it is among the least often present.
The reason it matters here is liquidity. There is no market for shares in a Nigerian private company. A minority shareholder cannot sell without finding a buyer the other shareholders will accept, and the articles usually restrict transfers anyway. Their realistic route to value is a sale of the whole company.
If the majority can sell their own stake without including the minority, that route disappears. The buyer has what they wanted, has no interest in acquiring the remaining shares, and the minority is locked in indefinitely.
The second Nigerian point is family and friend investment. A great many minority stakes in Nigerian companies are held by people who invested on the strength of a relationship with the founder. When that founder sells and exits, the relationship that justified the investment has gone, and the shares remain.
Tag-along, together with pre-emption and an exit mechanism, is what converts a minority stake from a permanent commitment into an investment.
The third is enforcement. The clause should prohibit the majority from completing a sale unless the buyer takes the tagging shares, and the company should be a party so that the directors cannot register a transfer made in breach. Without those, a majority determined to sell can complete and leave the minority with a damages claim rather than a sale.
Tag-along vs pre-emption vs exit right
Three mechanisms addressing a minority shareholder's ability to get out, at different moments.
Pre-emption operates when any shareholder wants to sell. The shares must first be offered to the other shareholders on the same terms. It gives the minority the chance to buy rather than to sell, and it can be a burden as much as a protection.
Tag-along operates when the majority sells to an outsider. The minority can require their shares to be included on the same terms, which is their route to the same exit.
An exit right, sometimes a put option or a mandatory buyback, operates on a timetable or on defined events. It entitles the minority to require the company or the majority to buy their shares after a period or on a trigger such as a failure to achieve an agreed milestone.
A minority investor in a Nigerian private company should have all three, because each addresses a different way of being stuck.
Limits and risks
Tag-along depends on there being a sale to tag onto. It provides no exit where the majority simply holds indefinitely, which is why an independent exit right matters too.
A proportionate tag also leaves the minority partly invested, which may not solve the problem.
The right binds only parties to the agreement, so shareholders who never signed are outside it.
And enforcement against a completed sale is awkward. Where a transfer has been registered in breach, the minority is pursuing a remedy rather than participating in the sale, which is why the clause should prevent completion rather than merely provide for damages.
Worth knowing
Insist on full tag rather than proportionate, and make the company a party so a transfer made in breach cannot be registered. A Nigerian minority shareholder with a proportionate tag and no registration block is still stuck with a stranger holding control.
Questions people ask
What is a tag-along right?
A right allowing a minority shareholder to join a sale by the majority, requiring that their shares be included at the same price and on the same terms.
What does it protect against?
Being left holding shares in a company now controlled by a buyer the minority did not choose, with no market for their shares and no way out.
What is the difference between full and proportionate tag?
Full tag allows the minority to sell their entire holding. Proportionate tag allows them to sell only the same proportion the majority is selling, which leaves them partly invested. Full tag is the stronger protection.
How does the clause work in practice?
The selling shareholder gives notice of the proposed sale and its terms, the minority has a defined period to elect to tag, and the majority may not complete unless the buyer also takes the tagging shares.
Why does it matter so much in Nigeria?
Because there is no market for shares in a private company. A minority shareholder's realistic route to value is a sale of the whole company, and without tag-along that route disappears when the majority exits.
What if the majority sells anyway?
Make the company a party to the agreement so that a transfer made in breach cannot be registered. Otherwise the minority is left pursuing damages rather than participating in the sale.
