Tag-along right

Definition

Where drag-along solves the buyer's coordination problem (force the minority into the deal), tag-along solves the minority's exit problem (don't leave me behind in a business with new ownership). They are contractual mirror images and almost always negotiated together in Benelux SHAs.

The mechanic. A majority shareholder receives a bona fide third-party offer for some or all of their stake. Before they can close, they must give formal "tag notice" to all tag-along holders. The minority then has 20-30 business days to elect to tag along: selling their pro-rata share into the same transaction at the same per-share price. The buyer either accepts all the tagging shareholders into the deal (potentially expanding the transaction size) or walks away: they can't selectively cherry-pick the majority while leaving minorities behind.

The Benelux nuance vs. Anglo-Saxon: equal-treatment requirements bind tighter (mirror of drag-along discussion: see [[drag-along-right]]). Belgian and Dutch courts disfavour structures where the majority gets a side payment, a kicker, or different warranty terms outside the tag-along base price. Practical implication: if a majority shareholder negotiates a "consultancy agreement" with the buyer post-closing at €500k, that side-deal can be re-characterised as part of the share-sale consideration and pro-rata distributed via the tag-along mechanism. M&A advisors structuring deals should anticipate this.

Where tag-along matters most: (1) early-investor protection in PE-backed companies (the angel doesn't want to be stuck with a new PE owner), (2) family-business minority protection (the second-generation cousin without operational involvement wants exit liquidity), (3) employee pool protection in management vehicles (when the founder sells, the management vehicle wants to ride along), (4) co-founder protection (where one co-founder has majority and the other(s) have minority stakes).

The partial-sale trigger is the most-negotiated variable. Three common Benelux 2026 structures: (1) "any-sale trigger": any majority sale (even partial) triggers tag, most protective for minority; (2) "change-of-control trigger": only sales that transfer control trigger tag, balanced; (3) "100%-only trigger": only full-exit sales trigger tag, most majority-favourable. The PE-backed deal standard is "change-of-control": minorities can ride along when the strategic acquirer takes the controlling stake.

A worked Benelux example. An Eindhoven SaaS company has four shareholders: founder (55%), early angel (15%), seed PE fund (20%), and employee pool via management vehicle (10%). The SHA contains "any-sale" trigger tag-along. In 2026 the founder negotiates a partial sale of 25% (out of his 55%) to a Belgian strategic at a €60m valuation. The angel, seed PE, and management vehicle all tag along on a pro-rata basis. The Belgian strategic ends up buying 25%/100% × all tag-along holders = approximately 11.25% angel sale, 15% PE sale, 7.5% management vehicle sale, plus the original 25% from the founder: total 58.75% transferred at €60m valuation. The transaction expands meaningfully beyond what the founder originally negotiated.

Worked example

Founder sells 25% of his 55% stake at €60m valuation = €8.25m. Angel (15%) tags pro-rata → sells 25%×15% = 3.75% for €2.25m. Seed PE (20%) tags pro-rata → sells 25%×20% = 5% for €3m. Mgmt vehicle (10%) tags pro-rata → sells 25%×10% = 2.5% for €1.5m. Total deal size: €15m (vs. founder's original €8.25m).

When it matters

Tag-along is essential minority protection in any SHA with PE investors, angels, or employee pools. Without it, the majority can exit at premium terms while minorities are stranded with new ownership. Negotiate the trigger threshold (change-of-control vs. any-sale) based on minority size: smaller minorities need more protective triggers. Pair with drag-along for symmetric protection of both sides.

Frequently asked

Can a buyer refuse to take tagging shareholders?

Yes, but at the cost of the entire transaction. The buyer's choice is binary: accept all tagging shareholders into the deal (potentially expanding deal size and total consideration), or walk away entirely. They can't selectively cherry-pick the majority. This is the structural reason why well-drafted tag-along is enforceable: it credibly threatens the underlying transaction.

Does tag-along apply if the majority sells to a related party?

Most Benelux SHAs explicitly cover this. The standard clause includes "any transfer to a related party at any value" within the tag-along trigger, often at the higher of (a) the related-party transaction price or (b) an independent fair-market-value assessment. This prevents the majority from circumventing tag-along by selling to a wholly-owned entity at a discount and then re-selling at full value.

What if the buyer values the majority's shares differently from minority?

Tag-along contractually requires identical per-share consideration. If the buyer offers different terms (e.g., majority gets cash + earn-out, minority gets cash only), Benelux courts typically enforce equal treatment: the minority can demand the same blended package. Best practice: SHA explicitly specifies that all consideration components (cash, earn-out, escrow, retained equity, side-payments) must be pro-rata distributed.
