How does a tag-along right protect minority stockholders differently than a drag-along right protects the majority?

A tag-along, or co-sale, right entitles minority stockholders to participate pro rata in a sale being made by a large stockholder to a third party, preventing a scenario where founders or early investors sell a significant block of shares to a buyer at favorable terms that smaller holders have no ability to access. This right is especially valued by early angel investors and seed-stage stockholders who otherwise have limited ability to achieve liquidity outside of a company-wide sale event.

Why is the threshold set for a drag-along provision so important to negotiate?

The specific voting threshold required to trigger a drag, for example requiring approval from a supermajority of preferred stockholders versus also requiring separate common stockholder approval, determines in practice who must consent before a sale can be forced through, and setting the threshold too high can make an otherwise attractive acquisition structurally difficult or impossible to execute. Founders and early investors should negotiate drag thresholds with a realistic eventual exit scenario in mind, not just current-round dynamics.

Are drag-along and tag-along rights standard or heavily negotiated terms?

Both provisions are standard features of the NVCA model legal documents commonly used in US venture financings, but the specific thresholds, carve-outs, and which classes of stock are subject to drag or entitled to tag are frequently negotiated on a deal-by-deal basis rather than accepted as boilerplate. Reviewing these mechanics carefully at each financing round matters because they compound across successive rounds as the capitalization table grows more complex.

Drag-Along and Tag-Along Rights

Stockholder agreement provisions that compel minority holders to join a sale (drag) or entitle them to participate pro rata in a major holder's sale (tag).

Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 9, 2026

Definition

Drag-along rights allow specified majority stockholders (typically the board plus a preferred-stock supermajority) to compel minority stockholders to sell their shares on the same terms in a qualifying sale of the company, ensuring a buyer can acquire 100% of the equity. Tag-along (co-sale) rights give minority stockholders the right to participate pro rata in a large stockholder's sale to a third party, preventing founders or early investors from cashing out at a price the smaller holders cannot access. Both are standard NVCA-form provisions.

What the regulation says

Drag-along and tag-along rights are contractual investment terms, not MedTech-specific regulatory requirements. The National Venture Capital Association (NVCA) provides model provisions through its Voting Agreement for drag-along rights and its Right of First Refusal and Co-Sale Agreement for tag-along rights. These models are drafting frameworks, not binding regulations. The executed agreements determine approval thresholds, covered transactions, participation rights, notice procedures and exceptions. A drag-along provision does not itself replace corporate approvals required by law or automatically eliminate statutory appraisal rights. For Delaware corporations, the Delaware General Corporation Law supplies the statutory framework: Title 8, § 202 addresses restrictions on stock transfers; § 218 addresses stockholder voting agreements; § 251 governs merger agreements and approvals; and § 262 governs appraisal rights. Section 122(18), effective August 1, 2024, expressly authorizes certain contracts between corporations and current or prospective stockholders, subject to statutory limits, including consistency with the certificate of incorporation and Delaware law. It does not make every drag-along or co-sale clause enforceable. Enforceability depends on the agreement, applicable corporate law and transaction facts. These rights concern ownership and exit arrangements, not medical-device market authorization.

What this means in practice

MedTech founders should understand drag thresholds carefully; they determine who must agree to a sale. Tag-along rights are especially important to early angels and seed investors.

Examples

A MedTech startup's board decides to sell the company to a larger firm, activating a drag-along clause that compels all seed investors to sell their shares on the same terms.
An early angel investor, holding a small stake in a MedTech company, uses their tag-along rights to join a large Series A investor's sale of a significant portion of their shares to a new institutional buyer.
To avoid holding out by a few small stockholders, a MedTech company contemplating an acquisition relies on a drag-along provision in its stockholder agreement to ensure a 100% equity transfer to the acquirer.

Common pitfalls

•Setting a drag threshold so high (e.g., requiring common-stockholder supermajority) that a clean exit becomes structurally hard.

Frequently asked questions

A drag-along right allows the stockholders specified in the governing agreement, typically the board together with a preferred stock supermajority, to compel all other minority stockholders to sell their shares on the same terms in a qualifying company sale, which is essential for a buyer that wants or needs to acquire 100 percent of the company's equity in the transaction. Without an effective drag-along mechanism, even a small number of holdout minority stockholders could block or complicate an otherwise agreed sale.
