Why sustainable, not reported, performance matters when valuing a business

For many business owners, valuation starts with the latest set of accounts. Revenue, profit and margins all matter, but they do not always tell the full story. Buyers and investors are usually more interested in the cash flow a business can reasonably sustain under normal conditions, not simply what it achieved in the most recent financial year.

In the first article in this series, Anupam Pandey, Associate Director Deal Advisory, BDO Auckland, looked at the broader factors that can influence business value, including expected cash flow, the reliability of those cash flows and market perceptions of risk. This article, the second instalment in a 3-part series on valuation, focuses on the factors business owners can influence more directly: What their financial results reveal about the sustainable cash flow that buyers and investors are ultimately valuing. 
 

“A strong set of accounts can look like proof of business quality, but valuation requires a more disciplined assessment. The question is not only what the business earned, but what a capable operator could reasonably be expected to repeat.” – Anupam Pandey, Associate Director Deals Advisory, BDO Auckland

 

Reported profit is not the same as sustainable business performance

A valuation asks what a business can reasonably be expected to produce under normal operating conditions, regardless of who owns or manages it. That question sits underneath common valuation methods. A discounted cash flow makes the assumption explicit through future forecasts, while a multiple applied to earnings often makes the assumption implicit by treating current or normalised earnings as a reasonable base.

In both cases, the judgement is similar: Whether the number in front of you reflects performance that can be repeated. For business owners, this means looking beyond revenue growth, earnings before interest, tax, depreciation and amortisation (EBITDA), and headline margins to understand what is genuinely sustainable.
 

How margins affect business valuation

Margins are often where sustainable performance is first tested. A recent improvement may be genuine, reflecting stronger pricing, better operating efficiency, or a more profitable customer or product mix. It may also reflect temporary conditions, such as prices rising before wage or supplier costs catch up, delayed recruitment, deferred maintenance, or a favourable run of projects that is unlikely to repeat.

The purpose is not to reward or penalise a particular owner’s decisions. It is to identify the margin profile a capable operator could maintain under normal conditions. For business owners, the useful question is whether improved margins reflect a lasting change in the business, or a temporary benefit that may unwind over time.
 

Why capital expenditure needs to be considered in valuation

Reported earnings do not necessarily show what the business will need to spend to keep operating at its current level, or to grow. A business that has recently completed a major investment programme may need lower capital expenditure for a period. Another that has deferred replacement or maintenance may face a higher future spend to preserve current earnings.
 

"Some capital spending simply maintains existing earnings, while additional spending is intended to create new capacity. If a valuation includes future revenue growth, it should also consider the investment required to support that growth. Pricing in growth without recognising the associated capital expenditure can overstate the business’s sustainable cash flow."

This is particularly important for asset-heavy businesses, where a strong profit result may not fully reflect the future investment needed to maintain operations.
 

How working capital can change the cash a business generates

Growth also has a funding requirement. It often appears in working capital rather than the income statement. A growing business may need to buy inventory before it earns the additional revenue, then wait for customers to pay. Supplier credit may help fund part of that gap, but it rarely covers all of it.

Two businesses can report similar earnings growth but generate very different amounts of cash. One may convert a large share of earnings into cash because stock turns quickly and debtors are collected promptly. Another may report a similar margin while inventory and receivables increase each time revenue grows.
 

“A forecast that assumes growth but ignores the working capital needed to fund that growth can create a misleading picture. The business may look profitable on paper while still consuming cash.”

For growing businesses, understanding this cash requirement can be just as important as understanding the profit margin.
 

Normalised EBITDA is only part of the valuation picture

Normalising EBITDA for one-off legal costs, unusual remuneration, non-recurring income or other adjustments can be useful. However, normalised earnings are not the same as sustainable cash flow. A business can have defensible normalised earnings and still convert little of that amount into cash that could be distributed or reinvested each year.

The adjustment can also work the other way. A weaker year may include temporary inefficiencies or input costs that are unlikely to recur. Recent investment may reduce future capital expenditure needs. Working capital may improve. Each of these factors could mean sustainable performance is above the reported result rather than below it.

Reported performance shows what the business achieved. Sustainable performance helps show what a buyer or investor may reasonably expect it to achieve in the future.
 

"For business owners, understanding this distinction can support better planning, whether they are preparing for a sale, considering investment, planning succession or simply looking to understand what drives value in their business."

Identifying sustainable cash flow is an important step in the valuation process, but it is not the final one. That cash flow still needs to be translated into value, whether through an earnings multiple or a discount rate. In the final article in this series, we will look at how that process works and why different valuation methodologies can produce different outcomes.
