What Are Drag-Along and Tag-Along Rights?
Drag-along is the right of a defined majority of shareholders to force every other shareholder to sell on the same terms in a qualifying exit. If 72% of the cap table votes to accept an acquisition offer, the remaining 28% are 'dragged along' — they must sign the same SPA, accept the same per-share price, and give the same warranties. Without drag-along, a single minority holder can block a sale by refusing to sign.
Tag-along is the mirror image: the right of minority shareholders to join a sale that a majority shareholder has negotiated for themselves. If a founder or a Series B investor sells 60% of the company to a strategic buyer, the minority holders have the right to 'tag along' and sell the same proportion of their own shares on the same terms. Without tag-along, the majority can take a control premium and leave the minority stranded with a new controlling shareholder they never approved.
Together, drag and tag are the two sides of a clean exit. Drag protects the acquirer (they get 100%); tag protects the minority (they get the same deal as the majority). Neither clause exists without the other in a well-drafted SHA.
How Drag-Along Mechanics Work
The drag-along clause defines four things: the threshold required to trigger it, who counts toward that threshold, what kind of transaction qualifies, and what carve-outs apply.
The threshold is the most negotiated element. Common structures are: (a) simple majority of all shares on a fully diluted basis (~50%+1); (b) supermajority such as 66% or 70%; (c) class-by-class consent (majority of common AND majority of preferred, voting as separate classes); (d) lead-investor consent on top of either of the above. Class voting matters most to founders because it gives common holders — typically founders and employees — an actual blocking right.
Qualifying transactions are usually defined as a sale of more than 50% of voting shares, a merger, or a sale of all or substantially all assets. A small secondary by one shareholder does not trigger drag.
Carve-outs commonly include: a minimum exit price (drag only triggers above a floor — protects investors from being dragged into a fire-sale that wipes out their preference), a maximum representations & warranties exposure for dragged minority holders (capped at sale proceeds), and a prohibition on non-compete obligations being imposed on minority sellers without consent.
How Tag-Along Mechanics Work
Tag-along triggers when a 'qualifying shareholder' (usually any holder above a defined threshold, e.g. 10%) proposes to sell to a third party. Before the sale can close, the seller must notify all other shareholders, who then have a defined window — typically 20 to 30 business days — to elect to participate.
If the buyer is only willing to acquire a fixed number of shares, the available slots are allocated pro rata to all electing shareholders, including the original seller. The selling shareholder cannot 'reserve' the full allocation for themselves.
The clause matters most in a secondary transaction where a founder or early investor sells a meaningful stake at a premium price. Without tag-along, only the favoured seller gets the premium; with tag-along, every minority holder gets a proportional bite. See [secondary transactions](/captable/secondary-transactions) for the broader mechanics.
Drag-along and tag-along are usually paired with [right of first refusal](/captable/right-of-first-refusal) procedures: the company and existing shareholders first get the chance to buy the offered shares before any third-party sale or tag election can complete.
Why These Clauses Matter for Founders
Three founder-specific risks are buried in standard drag-along language. First, the threshold can be met without any common-holder consent — meaning preferred investors alone can force founders and the ESOP into a sale they would not have approved. The fix is class-by-class voting (majority of preferred AND majority of common), which is unusual but achievable in seed rounds with strong founder leverage.
Second, dragged minority sellers can be exposed to unlimited representations and warranties. Standard drafting limits dragged holders to (a) reps about their own shares (title, no encumbrance) and (b) financial liability capped at sale proceeds. Without that cap, a minority founder dragged into a deal could be personally liable for indemnity claims that exceed what they received.
Third, the minimum exit price floor is often missing. Without it, a drag can be triggered at a price below the preference stack, leaving common holders with zero and a signature on documents that release all claims. Always negotiate either a minimum price (e.g. ≥1.5× total preferences) or a separate founder veto for sub-preference exits.
For tag-along, the founder-side risk is the inverse: as a founder considering a partial secondary at Series C, the tag-along clause means every other shareholder can join. Plan for it — your €3M planned liquidity event may turn into €1.5M after pro-rata allocation. See [secondary transactions](/captable/secondary-transactions).
Common Scenarios
Strategic acquisition with full drag: 80% of shareholders accept; remaining 20% (often disgruntled angels) are dragged. The 20% sign the SPA under protest but cannot block. Without drag-along, those 20% could have demanded a side payment to consent — a classic 'hold-out' problem.
Secondary at Series C with active tag-along: founders try to sell €4M in a tender. Every shareholder elects to tag. Available slots reallocate pro rata. Founders ultimately sell €1.6M of the €4M intended. Lesson: always negotiate the tender mechanics with the new investor to either (a) increase the tender size to absorb tag elections or (b) carve out founder secondaries from tag-along.
Down-side drag below preferences: acquirer offers €9M for a company with €11M of stacked 1× preferences. Drag triggers if there is no minimum-price floor. Common holders receive zero. This is why minimum-price floors matter. See [liquidation preference](/captable/liquidation-preference) and [exit waterfall](/captable/exit-waterfall) for the full math.
Cross-class disagreement: preferred wants to sell at €20M; founders believe the company is worth €50M in two years. Without class voting, preferred drags. With class voting, founders block. This is the single most consequential negotiation point in a Seed term sheet most founders never even discuss.
How CAPLINK Helps You Manage Drag and Tag Rights
CAPLINK's cap table module stores drag-along thresholds, class voting requirements, tag-along trigger thresholds, and minimum-price floors as structured data attached to the relevant share class. When you model an exit, the platform checks whether the drag majority is met under the current cap table, flags any sub-preference exit price, and surfaces the tag-along notice obligations triggered by each scenario.
The same data feeds the [data room](/dataroom) during due diligence — prospective acquirers see the consent map and immediately understand which signatures they need. It also informs the [exit waterfall](/captable/exit-waterfall) analyzer so payout tables reflect the contractual reality, not a clean theoretical waterfall.
Read [shareholder agreements](/captable/shareholder-agreements) for the broader SHA context, [board composition and voting control](/captable/board-composition-voting-control) for how board approvals interact with drag votes, and [exit waterfall](/captable/exit-waterfall) for the payout mechanics that drag triggers.
