Business valuation isn’t static. You can run all the numbers, calculate EBITDA, apply a sensible multiple, and balance the assets against the liabilities—and still miss the mark completely. Why? Because value is shaped not only by internal accounts, but by external forces: regulation, politics, and even world events.
All it takes is one new law, one crisis, or one headline for yesterday’s valuation to look obsolete.
The Impact of Regulation
Legislation can make or break industries.
Grenfell and cladding. After the Grenfell Tower tragedy, legislation around cladding and fire safety tightened dramatically. Overnight, property firms with cladded buildings saw portfolio values collapse. At the same time, specialist contractors in fire safety and remediation saw demand surge.
Manchester Arena bombing. New security laws around crowd control, CCTV, and barriers created mandatory demand for safety equipment suppliers. Their multiples rose not because the accounts changed overnight, but because the legal environment guaranteed future demand.
If you had valued these businesses based only on historic accounts, you would have missed the seismic shift in their prospects.
Why Buyers Must Think Beyond the Numbers
Numbers are a snapshot. Regulation is a movie. If you’re buying a business, you need to look at both.
A valuation based on last year’s performance tells you where the business has been. Legislation tells you where it might be going. If a new law mandates that every venue must buy a certain type of equipment, companies in that supply chain become more valuable. If a regulation bans a key material, companies dependent on it lose value immediately.
Ignoring this is how buyers end up overpaying—or missing out on opportunities.
Global Events That Distort Value
It’s not just regulation. Global events can change valuations overnight.
Covid-19. Entire sectors collapsed in value, while others (like online delivery and PPE suppliers) skyrocketed.
Russia’s invasion of Ukraine. Sunflower oil exports were disrupted, prices spiked, and food manufacturers had to scramble for alternatives. A company importing sunflower oil suddenly faced supply chain chaos.
Ever Given stuck in the Suez Canal. One ship blocked global trade, throwing off balance sheets and supply chains in multiple industries.
None of these were foreseeable in the accounts. But they all reshaped value.
How to Factor It In
When valuing a business, always ask:
What industry is it in? Some are more exposed to regulation than others.
What legislation is pending? Read government white papers, consultations, and proposed bills.
What external risks exist? Supply chains, commodity prices, geopolitical hotspots.
What opportunities are emerging? New compliance requirements, subsidies, or incentives.
This is where a SWOT analysis (strengths, weaknesses, opportunities, threats) becomes more than a buzzword. It’s a way of layering context onto the numbers.
Case Example: Fire and Safety vs Property
Two valuations done around the same time tell the story:
A fire and safety equipment supplier saw its multiplier rise because legislation forced venues to spend on their products. Demand was guaranteed, reducing risk.
A property company with significant cladded assets saw its net asset value collapse. Properties once worth millions became liabilities until remediation could be funded.
Both valuations started with EBITDA and assets. But only by factoring in legislation did we arrive at accurate ranges.
The Buyer’s Dilemma
Here’s where discipline is key. Sometimes a new law creates opportunity, but that doesn’t mean you should automatically overpay. For example, if legislation increases demand for a service, many buyers rush in, inflating multiples. You need to ask:
Will this demand be sustained?
How competitive is the market?
Does the business have the capacity to capture the opportunity?
Legislation creates winners and losers—but it doesn’t eliminate risk.
Why Sellers Often Miss This
Sellers are usually focused on their own books. They may not recognise how external changes affect their valuation—positively or negatively. A seller in a struggling sector may insist on old multiples, ignoring headwinds. A seller in a booming space may underplay how valuable their position has become.
As a buyer, your edge is in spotting these misalignments.
Practical Steps for Buyers
Do a legislative scan. Look at government websites, trade associations, and industry bodies.
Read industry press. Many acquisitions are announced publicly; these give clues about multiples in your sector.
Model scenarios. What happens if regulation tightens? If subsidies are removed? If a key supplier disappears?
Stress-test assumptions. Don’t just look at last year’s numbers—ask what next year will look like under new rules.
Get expert advice. Industry specialists can tell you what’s on the horizon long before it hits the mainstream.
The Bottom Line
Valuation isn’t just arithmetic. It’s context. EBITDA, multiples, and balance sheets give you the foundation, but legislation and global events redraw the map.
If you want to buy wisely, you can’t ignore the outside world. Sometimes it will boost your target’s value; sometimes it will destroy it. The key is to see it coming and price accordingly.
