Why valuation is not what you think it is: GAAP vs IFRS differences that change deal outcomes

Consider two economically comparable manufacturers, one headquartered in Europe and the other in the United States. Both operate equivalent facilities, carry similar inventory levels, lease comparable square footage, and generate nearly identical free cash flows. The two businesses enter sale processes in parallel.

When indicative bids are received, the valuations diverge materially. The businesses are operationally comparable, yet the financial statements that describe them are not.

This pattern appears regularly in cross-border transactions. The divergence does not arise from analytical error. Instead, it stems from the interpretive differences between US GAAP and IFRS, and the effect those differences have on reported metrics, market multiples, and ultimately transaction price. For deal professionals and businesses involved in international transactions, understanding where these frameworks diverge has direct practical consequences.

Intrinsic value is, in principle, the present value of future cash flows, and cash flows exist independently of accounting treatment. Whether an asset is depreciated over five years or ten does not change the cash leaving the business. Some practitioners therefore conclude that accounting standards are largely irrelevant to valuation. In practice, they are not.

Accounting choices directly shape the reported metrics that valuation professionals rely upon: EBITDA, EBIT, net income, leverage ratios, and the tax charge. In cross-border situations, normalizing financials to a consistent basis is now standard practice among experienced deal teams, not an optional refinement.

Revenue recognition (IFRS 15 vs ASC 606)

The two standards are broadly aligned on the five-step model for revenue recognition, but application differs in practice, particularly for long-term contracts, licensing arrangements, and variable consideration. Where timing differences arise, they shift the revenue and earnings profile across reporting periods. In the near-term DCF years, which carry the greatest weight in present value terms, even modest timing differences can produce a measurable effect on implied value.

Lease accounting (IFRS 16 vs ASC 842)

This remains the most material area of divergence for most operating businesses. Under IFRS 16, substantially all leases are capitalized on the balance sheet as right-of-use assets with corresponding liabilities. Operating lease expense is removed from the income statement and replaced by depreciation and interest. This produces structurally higher EBITDA, higher depreciation, and higher reported debt.

US GAAP (ASC 842) retains the distinction between operating and finance leases. Payments on operating leases continue to flow through operating expenses, resulting in lower EBITDA and less encumbered leverage ratios.

Benchmarking an IFRS-reporting entity against US GAAP comparables on unadjusted EV/EBITDA multiples therefore creates a structurally inconsistent comparison. In asset-heavy or lease-intensive businesses, the resulting distortion can be significant.

Inventory costing (LIFO under US GAAP)

US GAAP permits Last-In, First-Out (LIFO) inventory costing; IFRS prohibits it. In periods of sustained input cost inflation, LIFO produces lower reported inventory balances, reduced taxable income, and lower cash tax payments. That difference is economic, not presentational.

A US business reporting under GAAP using LIFO will show lower earnings and lower taxes than an economically equivalent IFRS-reporting entity. Valuation work on cross-border transactions requires adjustment for LIFO reserves to achieve a comparable earnings and asset base across frameworks.

Other areas of divergence

Additional differences relevant to practitioners include:

• R&D capitalization. IFRS permits capitalization of qualifying development costs once technical feasibility is established, while US GAAP requires substantially all R&D costs to be expensed as incurred. This can result in a materially higher asset base and smoother earnings profile under IFRS.

• ​Impairment testing. Differences exist in testing units, measurement approaches, and the ability to reverse impairment losses on certain non-goodwill assets. These affect book equity and credit-related metrics. 

• ​Deferred taxes and foreign currency translation. These areas can produce apparent earnings volatility that may have limited economic substance.

Law firms, investment banks, and advisory teams

The primary risk is comparables contamination. Benchmarking an IFRS-reporting target against US GAAP trading comparables without normalizing for lease accounting, inventory treatment, and revenue recognition timing can produce flawed multiples analysis. In competitive processes, this creates unnecessary negotiation exposure.

Experienced deal teams now routinely prepare normalization schedules that isolate IFRS 16 effects, adjust for LIFO reserves, and restate revenue timing differences before applying market-based methods. Advisors who identify and present these adjustments early are better positioned to frame and defend their analysis.

Privately held businesses

While most owner-managed businesses are not sold cross-border, a growing proportion of transactions involve buyers or lenders operating under a different accounting framework. Sellers preparing for exit should understand how their financials would appear to a buyer applying US GAAP or IFRS. This includes ensuring lease obligations are clearly visible and correctly classified, inventory methodologies are well documented, and any capitalized development costs are supported by appropriate records.

Buyers encountering unfamiliar accounting treatments during due diligence often apply an uncertainty discount. Sellers who anticipate and proactively address these differences maintain greater control over the narrative and typically retain more of the transaction proceeds.

Valuation in cross-border contexts requires careful translation between accounting standards: separating cosmetic differences from those with genuine economic consequences, adjusting for the former while preserving the latter.

Two businesses with equivalent cash-generating capacity can present materially different financial profiles depending on how they account for leases, inventory, or development expenditure. Recognizing the source of that divergence is the starting point. Restating, normalizing, and defending the analysis under deal-room scrutiny is the work that follows.

We will examine several of these topics in greater depth in our September research report.

From an Oudtshoorn ostrich farm to advising founders

In this episode, Graham speaks with Johan Potgieter, seventh-generation ostrich farmer turned chartered accountant, now founder of Thornberry Consulting and CEO of Lion Cage Consulting in Cape Town.

Johan and Graham dig into what actually builds business value: not a number a founder has fallen in love with, but a defensible one, built years before a deal is on the table. They talk candidly about the mistakes founders make when they wait too long, and why the numbers a business runs on have to hold up to scrutiny, not just optimism.

This is also a conversation about values in practice: what it means to walk away from lucrative but misaligned clients, why patience is a strategy rather than a weakness, and how a farm upbringing teaches you to think in seasons and cycles rather than quarters.

The UK’s Autumn Budget brought a number of changes to inheritance tax rules that make robust business valuations more important than ever. "What is my business worth?" is no longer just an exit-planning question. It's now an estate-planning question too, and the answer needs to stand up to HMRC scrutiny.

This is the topic that we explore in our featured article published in the latest edition of Steer Your Business.

Read the full piece here.

bizval’s founder and CEO, Graham Stephen, recently attended a community event put on by the SA Ubuntu Foundation. The main topic of discussion was how South African businesses were weighing up the pros and cons of operating across both local and international markets. Bashier Adam, director at Nexia SAB&T, shared practical perspectives on business structuring, governance, and managing risk in a changing economic environment. While Lize Steyn, director at Strategic Capital, discussed how investors can approach local and offshore opportunities with a long-term, risk-balanced mindset.

The main takeaway from the discourse was that sustainable growth is built on informed decision-making, sound financial strategy, and access to trusted advice. Thanks again to the SA Ubuntu Foundation for hosting us.
