Tag-along rights, also called co-sale rights, give minority shareholders the option to participate in any sale of shares initiated by a majority shareholder. If a controlling investor or founder sells their stake, tag-along provisions ensure smaller investors can exit alongside them on identical terms.
How Tag-Along Rights Work
The mechanics are straightforward. When a majority shareholder receives a bona fide offer to purchase their shares, they must notify all tag-along holders before closing the transaction. Those holders then have a window, typically 15 to 30 days, to elect participation.
If they exercise, the selling shareholder’s allocation is reduced proportionally. Say a founder holds 60% and an investor holds 10%. If a buyer wants 60% of the company, the investor can tag along and sell their 10%, meaning the founder actually sells 50% and the investor sells 10%.
If the buyer refuses to purchase the additional shares, the majority sale typically cannot proceed. This is the enforcement mechanism that gives the provision teeth.
Why Tag-Along Rights Matter
Without co-sale protection, a majority holder could negotiate a premium exit and leave minority investors trapped in an illiquid position with a new, unknown controlling shareholder. This is not a hypothetical concern. In private markets, where there is no public exchange to sell on, liquidity depends entirely on negotiated transactions.
Tag-along rights address three specific risks:
- Stranded minority position. A new majority owner has no obligation to offer liquidity to existing minorities.
- Valuation divergence. The majority sale price may reflect a control premium that minorities would never capture on their own.
- Governance shift. New controlling shareholders may alter the company’s direction, dividend policy, or exit strategy in ways that disadvantage remaining investors.
Tag-Along Rights in Fund Structures
In limited partnership structures, tag-along provisions are less common because LP interests are governed by transfer restrictions rather than co-sale mechanics. However, they appear frequently at the portfolio company level, where the general partner negotiates them as part of the investment documentation.
For co-investment vehicles, tag-along rights ensure that co-investors are not left behind if the lead sponsor sells its position in a secondary market transaction or GP-led secondary.
Negotiation Considerations
The key variables in a tag-along provision are the trigger threshold (what percentage sale activates the right), the notice period, and whether the right applies to all transfers or only third-party sales. Transfers to affiliates, estate planning vehicles, or other funds managed by the same GP are usually carved out.
Founders should pay attention to how tag-along rights interact with drag-along rights. In a well-drafted agreement, the drag-along overrides the tag-along in a full company sale, ensuring the transaction can close without individual holdouts.
Frequently Asked Questions
What is the difference between tag-along and drag-along rights?
Tag-along rights protect minority shareholders by letting them join a sale on identical terms. Drag-along rights protect majority shareholders by forcing minorities to participate in a sale. They are inverse protections that often appear together in the same agreement.
Are tag-along rights standard in venture capital deals?
Yes. Tag-along rights appear in nearly every venture capital term sheet, typically within the investor rights agreement or stockholders' agreement. They are considered a baseline investor protection and are rarely negotiated away.
When do tag-along rights get triggered?
Tag-along rights activate when a majority or controlling shareholder proposes to sell their shares to a third party. The minority holder receives notice and can elect to sell a proportional amount of their shares in the same transaction, at the same price per share.
