One of the most persistent myths in business is that a company’s worth can be read straight off its profit and loss statement. Add up a few years of profit, glance at the balance sheet, maybe factor in what the owner originally invested — and there’s your number.
It doesn’t work that way.
Accounting profit tells you how a business performed over a specific period. Business valuation is a different exercise altogether: it estimates the economic value of a business, or an ownership interest in one, for a defined purpose, as of a defined date, using an appropriate basis of value. It’s one of the most frequent (and expensive) errors businesses make to confuse the two.
Under the International Valuation Standards (IVS), valuation isn’t a back-of-the-envelope calculation. It’s a structured, professional process built on suitable methods, reliable data, sound assumptions, and considered professional judgement.
The Three Principal Valuation Approaches
1. Market Approach
Here, value is estimated by benchmarking the business against comparable companies, transactions, or other market evidence. Analysts commonly rely on valuation multiples — EV/EBITDA, EV/Revenue, or P/E — where they’re appropriate to the business in question. The logic is simple: what are similar businesses actually trading or selling for?
2. Income Approach
This approach looks forward rather than backward. Value is derived from the future economic benefits the business is expected to generate. A common way of doing this is through Discounted Cash Flow (DCF) analysis, which involves converting the expected future cash flows into a present value by applying an appropriate discount rate.
This is where an important principle comes into sharp focus: a business isn’t valued on what it earned yesterday, but on what it’s reasonably expected to earn tomorrow. Two companies with identical historical earnings can carry very different valuations depending on their outlook.
3. Cost Approach
The cost approach assesses value by reference to the cost of replacing or reproducing the relevant assets, adjusted as needed. It tends to be most relevant for asset-intensive businesses or for valuing specific categories of assets rather than an entire going concern.
Purpose and Basis of Value Matter
There is no universal “correct” valuation figure that applies regardless of context. A valuation might be needed for a merger or acquisition, a sale or purchase, an investment decision, financing or restructuring, a shareholder or commercial dispute, financial reporting, or a regulatory requirement.
Before any calculation begins, the purpose of the valuation and the applicable basis of value need to be clearly established. Terms like Market Value, Investment Value, and Fair Value are not interchangeable — each rests on different assumptions and circumstances, and each can produce a different conclusion of value for the very same business.
Why Profit Alone Can’t Determine Value
Imagine two companies reporting the same annual profit. Are they worth the same? Almost certainly not. Their valuations can diverge significantly because of differences in:
- Expected growth and future cash flows
- Customer concentration and the strength of recurring revenue
- Business and industry risk
- Debt levels and capital structure
- Dependency on key management
- Intellectual property and brand strength
- Working-capital requirements
- Market position and competitive advantage
Not all profits are the same, nor are all values the same. A business with a diversified customer base and a loyal customer base that is growing will likely have a higher value than a business with the same profit and a high concentration of customers with an uncertain future.
The IVS 2025 is set to feature a more focused examination of the quality of valuation.
The IVAL 2025 (effective from 31 January 2025) now prioritises the quality of data and inputs, the rigor of the valuation models, the documentation and quality controls. The updated standards also give more consideration to ESG-related factors where they have a genuine bearing on value.
More than that, the standards emphasize the importance of cross-checking: using multiple valuation methods, as appropriate, bolsters the soundness of a valuation conclusion, which is important, especially in the case of making M&A and investment decisions, where a single-method perspective can leave out critical context.
Valuation Is a Range of Judgement — Not False Precision
Valuation inherently depends on assumptions about future performance, risk, and market conditions. It involves a certain amount of uncertainty, so it’s not necessarily a red flag of trouble.
The key is that the methodology, data, assumptions, and professional judgement used in creating the number are suitable and substantiated, and their work is well documented. It is more convincing to have a well-founded valuation with admitted uncertainty than a valuation that seems to be precise.
The Key Takeaway
Profit tells us how a business performed. The purpose of valuation is to find the worth of the business. There is one interdependence, but not the same — and the belief that the two can be switched can result in bad trade-offs, bad fights, and bad financial reporting.
