Why this matters
Three weeks ago I told a founder her business was worth EUR 2.9M. Her broker had promised EUR 4.0M and the buyer opened at EUR 2.3M. The gap was not growth, it was risk: 31% of revenue in one client and a founder who still signed every major contract.
I learned this the hard way early in my career. I once anchored a seller to a 7x EBITDA headline and ignored concentration. The offer came back at 5.6x and we lost three months rebuilding the file.
Here is my view on how to value a business in 2026: start with cash flow and risk, then triangulate with market multiples. Most advisors will disagree, but I price risk before I price growth.
What buyers actually pay for
Look, buyers do not pay for your story. They pay for durable cash flow and reduced risk. In my files the average gap between an owner expectation and a buyer model is 20-40%, and it almost always comes from risk assumptions, not the math.
When owners ask me how to value a business, I start with the risk story. Most advisors will disagree, but I price risk before I price growth. A 15% churn assumption or a 30 day swing in working capital can change value more than another year of top line growth.
If you cannot explain your valuation in three sentences, you cannot defend it in a negotiation.
- When one customer is 30%+ of revenue, I haircut the multiple by 0.5-1.5x.
- Founders who sign every deal create key person risk buyers price hard.
- Weak cash conversion is a bigger red flag than slow growth.
Three methods I use and how I combine them
1. Discounted cash flow (DCF)
2. Market multiples
3. Asset based floor
How to value a business by normalizing earnings
This is where most owners lose value. You cannot multiply messy earnings. I rebuild EBITDA or SDE by removing true one offs, founder perks, and costs that will not exist post sale. This step is the core of how to value a business for any buyer.
I got this wrong once and it hurt. I left a USD 180K implementation project inside EBITDA because the owner insisted it was core. The buyer called it non recurring, cut the offer by USD 240K, and we lost six weeks. I do not repeat that mistake.
If you are not sure whether to use SDE or EBITDA, match the metric to buyer type. Strategic buyers want EBITDA. Small business buyers often anchor on SDE.
- Separate owner compensation from market salary and document the gap.
- Remove real one offs only, not recurring costs wearing new names.
- Reconcile add backs to invoices so a buyer can verify them fast.
Risk discounts that silently cut your multiple
Northfield Manufacturing in Manchester had GBP 2.3M in revenue and GBP 340K of EBITDA, but 35% of revenue sat with one customer. On paper it looked like a 6.5x deal. In reality we got 5.8x after 14 months of de risk work. The concentration almost killed the deal.
Brightside Care had a different problem. The founder still owned every major client relationship. Buyers assumed a 12 month transition and priced the risk. Once we built a second layer of leadership, the multiple stabilized at 6.2x.
This is why how to value a business is really how to price risk. Here is what I fix first: concentration, key person risk, and working capital. These three items move value more than any market headline. Once the risks are managed, picking the right valuation method determines whether you price conservatively or leave money on the table.
- Keep any single customer below 20% of revenue where possible.
- Document processes so the business runs without the founder.
- Clean up AR aging and inventory so cash conversion is real.

Key takeaways
Conclusion
Valuation is not a single number you defend once. It is a range you can explain and a risk story you can support. If you have clean earnings, a credible forecast, and a clear view of risk, buyers follow you. If you do not, they price the uncertainty and you feel it in the multiple.
If you want a professional baseline without hiring a full M&A team, use Valuefy to build a defensible valuation range and stress test it before you go to market. That is exactly what we built it for.
That is how to value a business without hoping the market saves you. Start with the basics, tighten the risk story, and keep the valuation updated as the business changes. It is the fastest way to protect value when you finally decide to sell.
Frequently asked questions
How often should I value my business?
I refresh valuations annually, and again after any major change such as a new contract, a price increase, or a market shock. If you plan to sell within 12 to 24 months, update every six months.
How to value a business if I am not selling yet?
I still value it. The point is to see which drivers move price and which risks need time to fix. A baseline today lets you measure progress every quarter.
Can I value my business myself?
You can build a rough view, but buyers will challenge your assumptions. If you do it yourself, use DCF plus comps and be honest about risk. A structured report saves time in diligence.
What is the difference between enterprise value and equity value?
Enterprise value is the value of the whole business before debt and cash. Equity value is what shareholders take home after debt. I start with enterprise value and bridge to equity at the end.
