The situation

Tesfay, a software developer, and Sophia, a pharmacist, started a company in London four years ago to build scheduling and inventory software for independent pharmacies. Two more people joined as shareholders early on, drawn in for capital and industry contacts rather than day-to-day work. By the time they came to Treadstone Law, the four of them held shares in proportions that had never been written down anywhere except a spreadsheet: Tesfay and Sophia together held a clear majority, and the other two held meaningful minority stakes.

They wanted a shareholder agreement — the contract that governs how a private company's owners deal with each other, covering things like how decisions get made, what happens if someone wants to leave, and what happens if someone dies or can't work anymore. Most founders treat this document as paperwork to get through before the real business starts. Our team treated it as insurance against a specific kind of failure: a company that becomes unsellable because one shareholder won't cooperate.

The agreement we drafted included two provisions that draw little attention when they're signed and enormous attention the day they're needed: drag-along rights and tag-along rights. A drag-along right lets shareholders holding a specified majority force the remaining minority shareholders to sell their shares on the same terms, if the majority agrees to sell the company to an outside buyer. A tag-along right runs the other way — it lets minority shareholders insist on selling alongside the majority, on the same terms, rather than being left behind as a minority owner of a company under new control. Together, they exist so that a company can actually be sold as a whole, rather than fragmenting into a majority that leaves and a minority stuck holding shares nobody else wants.

When the offer came

The company grew faster than any of the four had expected. Within four years, annual revenue reached roughly $13 million, and a larger health-technology company approached with an offer to buy it outright — an all-cash acquisition valued at approximately $19 million once debt and working capital adjustments were factored in. For Tesfay and Sophia, who had built the product and run the business daily, it was the outcome they had been working toward.

One of the other two shareholders agreed readily. The fourth — call the group's resistant member the holdout for the purposes of this story — did not. This shareholder held a minority stake, had not been involved in day-to-day operations for over a year, and had a private view that the company was worth considerably more than the acquirer was offering. There was no dispute about the company's numbers or the acquirer's good faith; the holdout simply preferred to keep the shares and wait for a better offer that might never come.

Selling a company outright can be structured in more than one way, but a buyer acquiring the entire company by purchasing all its shares typically wants exactly that — all the shares, not most of them. A buyer left facing one uncooperative minority shareholder after closing has to worry about that person requesting company records, questioning management decisions, or simply being a permanently unhappy business partner to the people who now run the company. Sophisticated acquirers routinely walk away from deals rather than accept that risk, or they cut their offer price to account for it. The holdout's refusal, in other words, was not a nuisance — left unresolved, it could have killed a $19 million sale for everyone, including the person refusing to sell.

What we did

  1. Confirmed the drag-along threshold was actually met. The shareholder agreement required a specified supermajority of shares to trigger a drag-along sale — high enough that a small clique of shareholders couldn't force out everyone else, but achievable by a genuine majority acting together. We reviewed the share register and confirmed that Tesfay, Sophia, and the third, cooperating shareholder collectively held well above that threshold, meaning the mechanism was available to them.
  2. Checked the agreement's process requirements line by line. A drag-along right is only enforceable if the company follows the exact procedure the agreement sets out — usually written notice to the dragged shareholder within a set window, disclosure of the deal terms, and confirmation that the dragged shareholder receives the same price and conditions as everyone else. We drafted the drag-along notice to match those requirements precisely, because a notice that skips a step gives a reluctant shareholder grounds to challenge the whole process later.
  3. Delivered formal notice to the holdout shareholder. The notice set out the acquirer's terms, confirmed the majority's election to invoke the drag-along provision, and gave the required period for the holdout to review the deal and raise any objection permitted under the agreement — objections limited to whether the process itself had been followed correctly, not to whether the holdout personally liked the price.
  4. Negotiated directly with the holdout's own lawyer. Rather than simply relying on the legal mechanism and inviting a dispute, we opened a direct conversation explaining what the drag-along clause meant in practice, what a challenge would likely cost in legal fees relative to the shares at stake, and how the price compared to independent indicators of the company's value that had come up during the acquirer's due diligence. This wasn't a threat; it was giving the holdout's own counsel the information needed to advise their client realistically.
  5. Coordinated the closing mechanics so every shareholder was treated identically. We worked with the acquirer's counsel to ensure the closing documents, escrow arrangements, and payment timing were the same for all four shareholders, with no side deals or different terms for anyone — the surest way to keep a drag-along sale free of later claims that the majority favoured itself.

The outcome

The holdout shareholder's lawyer reviewed the shareholder agreement, confirmed the drag-along process had been followed correctly, and advised their client that a challenge was unlikely to succeed and would cost more in legal fees than any realistic gain. Within about six weeks of the initial notice, all four shareholders signed the closing documents together. The sale closed on the timeline the acquirer had proposed, at roughly $19 million, with each shareholder paid out in proportion to their holdings and on identical terms.

Tesfay and Sophia, as the majority who had built the company, received the largest share of the proceeds and moved on to their next venture. The two minority shareholders, including the one who had initially resisted, were paid the same price per share as everyone else — the entire point of a properly drafted drag-along right. Nobody was left holding shares in a company under new ownership they hadn't chosen, and the acquirer got the clean, unanimous transaction it needed to proceed with confidence.

What made this a clear win rather than a drawn-out dispute was timing that had nothing to do with the day the offer arrived. The drag-along and tag-along rights had been negotiated and agreed to four years earlier, while all four shareholders were on good terms and none of them knew which side of a future disagreement they would end up on. That is the only point at which these clauses can be fairly negotiated — once an offer is on the table, the shareholder who stands to be dragged has every incentive to fight the very idea, and the shareholders who want to sell have every incentive to rush the clause through without real negotiation. Signing early, before anyone knew who would want to sell and who wouldn't, is what made the clause impossible to seriously dispute later.

What you can learn from this

  • Negotiate drag-along and tag-along rights when you sign a shareholder agreement, not when a buyer shows up. Once an offer exists, every shareholder can see exactly how the clause will affect them, which makes fair negotiation nearly impossible.
  • A drag-along right only works if the agreement's exact process is followed — the right notice, the right timeline, and identical terms for every shareholder. Skipping a step hands a reluctant shareholder grounds to fight the sale.
  • A buyer who wants to acquire a private company usually wants all the shares, not most of them. One uncooperative minority shareholder can reduce the price a buyer is willing to pay, or end the deal entirely, if the shareholder agreement provides no way to bind them in.
  • Tag-along rights protect the people without a drag-along clause to use — if you're a minority shareholder, they guarantee you get to sell on the same terms as the majority instead of being left behind with a new, unfamiliar controlling owner.
  • A shareholder agreement drafted while everyone is getting along is worth more than one drafted under pressure. The clauses that feel like unnecessary formality in year one are often the ones that save the deal in year four.
