Growth shares — equity that starts from zero
Growth shares are a way of giving someone a stake in a company's future growth without giving away any of its existing value. They're common in businesses that have outgrown EMI limits, and in PE structures where the investor wants management's incentive pointed strictly at value creation from here.
The mechanism
A new class of shares is created that only participates in value above a hurdle — typically set at, or slightly above, the company's current value. If the company is worth £50m today and the hurdle is £55m, the growth shares share in proceeds above £55m and receive nothing below it.
Because the shares are worthless if the company never clears the hurdle, their market value at the time of the award is low — which is what makes them affordable to subscribe for, and what generally keeps the future upside in capital-gains territory rather than employment income. That treatment usually depends on paying the (modest) market value at acquisition and filing a section 431 election within 14 days — a short form with long consequences.
What decides whether yours is a good deal
- The hurdle level. A hurdle at today's value is a genuine "share in all growth" instrument. A hurdle 30% above today's value means significant growth happens before your shares see their first pound. Neither is wrong — but they're very different deals sold under the same name.
- The premium above the hurdle ("kicker") and any catch-up. Some structures let growth shares participate more steeply once the hurdle clears, or catch up as if from a lower base. The waterfall mechanics decide what a headline exit number becomes in your hands.
- Leaver treatment and vesting. Growth shares are shares, so the compulsory-transfer machinery in the articles applies — the same good/bad leaver questions as any other management equity.
- Valuation discipline at award. The low entry price relies on a defensible valuation of the growth shares at grant. Established valuation practice exists for this; a company that hand-waved it has left tax risk sitting with you.
Reading your own award
Three documents tell the story: the articles (class rights and the hurdle mechanics), your subscription paperwork (what you paid, when), and the s431 election (whether it was made and filed in time). From those, the useful exercise is to model two or three exit values and watch what your class actually receives at each — the hurdle turns intuition about "my percentage" into a curve, and it's the curve that matters.
FAQ
How are growth shares different from options?
Growth shares are real shares you own from day one, with a hurdle limiting their economics; options are a right to acquire shares later. Growth shares usually involve a small payment now and capital-gains treatment on growth; unapproved options push the tax event to exercise, at income-tax rates on the gain to that point.
What happens if the company is sold below the hurdle?
The growth shares receive nothing (or a token amount, if the terms provide one). That's not a failure of the structure — it's the deal: no growth, no participation.
What is a section 431 election, in one sentence?
It's an election to be taxed on the shares' full unrestricted value at acquisition — usually a small number for growth shares — in exchange for keeping all later growth out of employment-income tax, and it must be made within 14 days of acquiring the shares.
