What Is an EMI Share Valuation?

An EMI share valuation is an independent calculation of the per-share market value of a UK private company, used to set the exercise price of options granted under the Enterprise Management Incentive scheme. It is the document HMRC's Shares and Assets Valuation team (SAV) uses to agree the price at which your employees can buy shares in the future, and the figure on which every subsequent tax outcome under the scheme is calibrated.

Done properly, the valuation is brief, defensible and dull. Three or four pages of methodology and a number you can rely on for 90 days. Done badly, it is the single most common reason an option grant fails to deliver the tax treatment everybody assumed it would. This article explains what an EMI valuation actually is, what it is for, what HMRC looks at, and where owners go wrong.

Why HMRC cares about the number

The EMI scheme is one of the most generous tax-advantaged share schemes available in the UK. Provided the option is granted at or above market value, the employee pays no income tax or NIC on grant, no income tax on exercise (on the discount to current value), and on the eventual sale of the shares the gain is treated as a capital gain, typically qualifying for Business Asset Disposal Relief if the holding-period and personal-company tests are met.

Those reliefs exist to incentivise long-term ownership in genuinely growing private companies. To stop them being used to convert salary into capital gains, HMRC requires the exercise price to be set fairly. The valuation report. Combined with form VAL231. Is the mechanism by which they confirm the price is reasonable. Once SAV agrees a number, the company has 90 days of price certainty to grant options at that level.

If a grant is made at below market value without HMRC agreement, the discount becomes a taxable benefit on exercise. Taxed at marginal income tax rates plus, in many cases, NIC. The CGT-treatment benefits on the original discount are lost. Employees who thought they had EMI options effectively end up with a hybrid that is worse than either a clean EMI grant or a straightforward bonus.

AMV and UMV. The two numbers in every report

Every EMI valuation has to give HMRC two numbers per share class: the Actual Market Value (AMV) and the Unrestricted Market Value (UMV). AMV reflects the value of the shares with their restrictions in place. Drag-along, pre-emption, leaver provisions, transfer restrictions and so on. UMV is the same shares stripped of those restrictions, as if freely tradeable.

AMV is the figure that anchors the option's exercise price for the purpose of preserving the tax reliefs. UMV matters for the £250,000 individual limit and the £3m total company limit on EMI grants. Both tested at unrestricted market value. The gap between AMV and UMV depends entirely on how restrictive the articles and any shareholders' agreement are; a typical SME with normal pre-emption and drag provisions will see a discount in the range of 10–30%.

It is the company's responsibility, with help from the adviser, to identify and describe every relevant restriction. SAV will not infer them from a passing reference in the report; they want a specific list with a reasoned discount applied. Vague reports get challenged and slow the process; specific reports usually clear in two to four weeks.

How the valuation is built

The starting point is the enterprise value of the company on a reasonable, defensible basis. For most owner-managed companies that is a multiple of maintainable EBITDA, cross-checked against sector comparables and any recent transactions. For early-stage companies with limited earnings history, the methodology shifts towards revenue multiples, prior funding rounds and benchmark data from comparable raises.

From enterprise value the report moves to equity value by adjusting for net debt, surplus assets, and any debt-like items. Equity value is then allocated across the share classes in the cap table. Taking account of preference rights, accrued dividends, conversion rights and any liquidation waterfall. The per-share UMV falls out of that allocation; the per-share AMV is derived by applying the restriction discount.

The narrative around those numbers is what SAV actually reads. They want to see: a clear description of the business and its trading record; the basis of the maintainable earnings figure; the multiple chosen and why; the cap table and any unusual rights; the list of restrictions; and the resulting per-share AMV and UMV. The arithmetic itself rarely causes a problem. It is the missing context that creates back-and-forth.

When you need one (and when you don't)

You need an HMRC-agreed EMI valuation before granting options whenever the company has any features that put the exercise price in doubt, which, in practice, is almost always. The exceptions are narrow: a brand-new company with no trading history and a freshly subscribed nominal share capital can sometimes grant at nominal value without a formal report, but anything beyond that benefits from the certainty SAV agreement provides.

You will also need a fresh valuation whenever something material changes. A funding round, a significant new contract that re-rates the business, a substantial change in trading, or the simple passage of time beyond the 90-day window. Re-using an expired valuation is one of the most common process failures we see, and it removes the price-certainty protection HMRC's agreement provides.

If you are issuing actual shares (not options) to employees outside an approved scheme, a valuation is equally important. There the relevant test is Employment Related Securities legislation rather than EMI rules, but the same disciplines apply.

What you provide; what the adviser produces

A typical EMI engagement asks the company for: the last three years of statutory accounts; the latest management accounts and a current-year forecast; the cap table with rights for each share class; the articles and any shareholders' agreement; details of any options already in issue; the plan rules under which the new options will be granted; and a short description of the business model and recent trading.

The adviser produces the valuation report, the supporting calculations, a draft VAL231 form for HMRC, and. Once SAV agrees the number. A confirmation letter that becomes part of the grant pack. Most engagements complete in two to four weeks from receipt of full information; rushed processes are usually rushed because something was missing, not because HMRC is slow.

Common mistakes

The most common mistake is granting first and valuing second. Boards sometimes minute the grant of options 'subject to valuation' and then are surprised when SAV comes back with a number that is materially different from the placeholder used in the option agreement. The grant either has to be re-papered (with all the disclosure and accounting consequences that follow) or accepted at a price that does not match the documented exercise price, which can taint the EMI status of the grant.

A second common mistake is using a valuation done for another purpose. A recent investment round, an internal share transfer, a probate valuation, and assuming it works for EMI. It usually doesn't. The methodology, the date, and the AMV/UMV distinction are all specific to the EMI regime. Re-purposed valuations frequently get pushed back by SAV.

A third is misjudging the restriction discount. Aggressive discounts that minimise AMV (and therefore the exercise price) without a clear list of substantive restrictions invite challenge. Equally, applying a token discount to articles that are heavily restrictive over-prices the option and reduces its motivational value. The discount should follow the articles, not the desired outcome.

What good looks like

A good EMI process is short, predictable and documented. The board agrees the option pool, the adviser produces a valuation in a couple of weeks, SAV agrees the number, the grant is made within the 90-day window, the option agreements are signed, and the EMI notifications are filed with HMRC within the statutory deadline. Everybody knows what the shares are worth, on what basis, and why.

Years later, when the company is sold and an employee exercises and sells in one go, the chain of evidence is intact: a defensible AMV, an HMRC agreement at the time of grant, a clean cap table, and a CGT calculation that holds up to scrutiny. That is what the modest cost of a proper EMI valuation buys you.

EMI for early-stage versus established companies

The valuation methodology shifts depending on the stage of the company. For a profitable, established SME with three or four years of consistent EBITDA, the work centres on a multiple of maintainable earnings cross-referenced to sector comparables. Much the same as a trade-sale valuation, but framed for SAV's specific lens. The restriction discount is the main variable; the earnings number is well-evidenced.

For an early-stage, pre-profit business, the methodology shifts towards revenue multiples, benchmark data from comparable funding rounds, and an allocation across the cap table that respects preference rights. The most recent priced funding round is usually the strongest single anchor, but with a careful explanation of why the EMI pool's ordinary shares sit lower in the waterfall and therefore command a meaningfully lower per-share value than the headline preference price.

Mid-life companies that have raised once or twice and are growing into profitability sit between the two methodologies. A blended approach. Earnings cross-checked against the round price, with explicit ordinary-share allocation, typically clears HMRC cleanly. The narrative around the choice of method matters more than the choice itself.

Common cap-table complications

A handful of cap-table features routinely complicate EMI valuations and need to be flagged early. Preference shares with accruing dividends or a multiple of liquidation preference change the waterfall and depress ordinary per-share value. Convertible loan notes that have not yet converted need a methodology choice. Convert on as-if basis, or treat as debt. Anti-dilution provisions can affect the post-grant economics of the option pool. SEIS/EIS-eligible shares with their own restrictions need to be modelled separately.

Founder vesting that is still in flight, unpapered option promises from earlier years, and side-letters with strategic investors all surface during the cap-table review. The valuation report has to reflect the company as it actually is, not as the cap-table spreadsheet says it is. A pre-engagement cap-table tidy-up is one of the most valuable hours of work before commissioning the valuation itself.

The most pragmatic move at the start of an EMI engagement is a short pre-engagement call between the valuer, the company secretary and the lead finance person, in which the cap table is walked through line by line, every share class right is confirmed against the articles, and any outstanding option promises, warrants or convertible instruments are listed. That conversation typically takes under an hour and removes most of the back-and-forth that otherwise stretches the formal engagement.
