IFRS 18 Reclassification and Investor Communication: A Practitioner Walkthrough
IFRS 18 investor communication reclassification is the practical challenge that most implementation guides skip. The standard's mechanics are well-documented. What is not documented is what happens when your restated 2026 operating profit lands in the 2027 annual report looking materially different from the number you told analysts about on every earnings call for the past three years.
This walkthrough is for CFOs, IR heads, and finance teams at IFRS-reporting companies who need to know which line items move, what the new MPM disclosure note requires, and how to get ahead of the investor conversation before the 1 January 2027 effective date.
Key takeaway: IFRS 18 does not change what you earn. It changes what you call it, where it sits in the income statement, and what you must now reconcile in the audited notes. For listed companies, the investor communication risk is as significant as the accounting work.
What Reclassification Actually Means Under IFRS 18
IFRS 18 requires every item of income and expense to sit in one of five defined categories: operating, investing, financing, income taxes, or discontinued operations. Two new mandatory subtotals follow from this structure: operating profit or loss, and profit or loss before financing and income taxes. Both are defined by the standard, not by management.
Under IAS 1, companies had wide latitude over income statement structure. That latitude is gone. The practical consequence is that items you have historically presented as operating may need to move to investing or financing, and vice versa. This is the reclassification problem.
The IASB designed operating profit as a residual: it captures everything not classified in the other four categories. That sounds simple. In practice, the investing and financing category definitions pull a surprising number of items out of operating for non-financial companies.

The Reclassification Map: Which Items Move and Why
The table below covers the income and expense items most likely to shift categories for non-financial companies. The key judgment in every case is whether the item relates to the entity's main business activities, a new concept introduced by IFRS 18 with no direct IAS 1 equivalent.
| Item | Typical IAS 1 treatment | IFRS 18 category | Key judgment |
|---|---|---|---|
| Interest income on cash and short-term deposits | Often operating or 'other income' | Investing | Unless providing financing is a main business activity |
| Dividends received from equity investments | Often operating or 'other income' | Investing | Unless investing in assets is a main business activity |
| Share of profit of associates / JVs | Often operating | Investing (always) | No exception for main business activities applies to equity-method investees |
| Interest expense on borrowings | Often operating (above EBIT) | Financing | Unless providing financing is a main business activity |
| FX gains/losses on trade receivables | Operating | Operating | Follows the category of the underlying item |
| FX gains/losses on borrowings | Often operating or 'other' | Financing | Follows the category of the underlying liability |
| Gains on disposal of PP&E | Often operating or 'other income' | Operating | If PP&E is used in main operations; investing if it generates returns independently |
| Income from investment properties | Often operating | Investing | Unless investing in properties is a main business activity |
| Government grants | Often operating | Operating | Typically stays operating if related to main activities |
| Current/past service cost on defined benefit pensions | Operating | Operating | Stays operating; only unwinding of discount moves to financing |
| Unwinding of discount on provisions / pension liabilities | Often operating | Financing | Classified with financing liabilities |
| Gains/losses on derivatives not in a hedge relationship | Varies | Follows the underlying exposure | FX derivative on a borrowing goes to financing; on a receivable goes to operating |
Two items deserve particular attention.
Share of profit of associates is the most common surprise. Under IFRS 18, income from equity-accounted investees always goes to investing, regardless of how central those associates are to the business. An industrial holding company that currently includes a material share of associates' profit in its operating line will see that number disappear from operating profit on restatement. For some companies, this is a double-digit percentage shift in the operating profit figure.
Foreign exchange differences require transaction-level tracking. KPMG's IFRS 18 guidance notes that FX differences on monetary items must be classified in the same category as the underlying transaction. FX on a trade receivable goes to operating. FX on a borrowing goes to financing. Many current ERP configurations aggregate all FX into a single P&L line, which will not survive IFRS 18 without system changes.
How 'Main Business Activities' Drives Every Classification Decision
The single most important judgment under IFRS 18 is defining your entity's main business activities. This concept determines whether items that would ordinarily sit in investing or financing instead stay in operating.
The standard identifies two specified main business activities that trigger this override:
- Investing in particular types of assets (debt and equity investments, investment properties). A real estate company whose primary activity is owning and leasing property would classify rental income and property-related gains in operating, not investing.
- Providing financing to customers. A bank classifies interest income from customer loans in operating. An industrial company that routinely offers long-term vendor financing to customers may also qualify, but this requires careful analysis and documentation.
The practical steps for documenting this judgment:
- Review your entity's stated purpose, business model description, and segment reporting to identify activities that generate the majority of revenue and profit.
- Assess whether investing in assets or providing financing to customers is a primary, not incidental, activity.
- Document the conclusion with reference to the standard's criteria and your business model evidence.
- Have the conclusion reviewed by your auditor early, because it gates every other classification decision.
Note one hard rule: income from associates and joint ventures accounted for under the equity method always goes to investing. There is no main business activities override for equity-method investees. This is not a judgment call.

Sector-Specific Reclassification Hotspots
Generic guidance only gets you so far. The reclassification impact varies significantly by sector.
Banks and financial institutions: Interest income from customer loans stays in operating because providing financing is a main business activity. The investing and financing category definitions largely do not apply in the way they do for industrials. The bigger challenge for banks is the MPM disclosure note and the disaggregation requirements.
Real estate companies: Rental income and property-related gains are typically operating if investing in properties is a main business activity. But income from financial investments held alongside the property portfolio (e.g. equity holdings, cash deposits) moves to investing. Companies with mixed portfolios need to draw a clear line.
Industrials and diversified manufacturers: The highest reclassification exposure. Interest income on cash, dividends from minority holdings, share of profit of associates, FX on borrowings, and the unwinding of discount on provisions all move out of operating. For a large industrial with significant net cash and equity-accounted investees, the restated operating profit could be materially lower than the IAS 1 figure.
Technology companies: Often hold significant cash and short-term investments. Interest income on those holdings moves to investing. Companies that communicate 'operating income' as a key metric will need to explain the change to analysts who have built models on the historical series.
Mining and resources: Decommissioning provisions are common. The unwinding of the discount on those provisions moves to financing under IFRS 18, out of operating. Government grants related to exploration or production typically stay operating.
The MPM Disclosure Note: What It Requires and Why It Matters for Investor Trust
A management-defined performance measure (MPM) under IFRS 18 is any subtotal of income and expenses that management uses in public communications outside the financial statements to communicate its view of the entity's financial performance, where that subtotal is not required or commonly listed by IFRS standards.
Common examples: adjusted operating profit, adjusted EBITDA, underlying earnings. What is not an MPM: cash flow measures (free cash flow), balance sheet ratios (return on equity), or non-financial KPIs (occupancy rates, same-store sales).
For each MPM, IFRS 18 requires a dedicated note in the financial statements that includes:
- A description of why the MPM provides useful information about financial performance
- A reconciliation to the nearest IFRS-defined subtotal, line by line
- The tax effect of each reconciling item
- The non-controlling interest effect of each reconciling item
This is a significant governance shift. Non-GAAP measures that companies have communicated in earnings releases and investor presentations for years will now be reconciled inside the audited financial statements. Auditors will audit those reconciliations. That changes the review and sign-off process for every adjusted metric your IR team publishes.
EY's IFRS 18 analysis describes this as requiring "multidisciplinary cooperation on new performance measures and systems" and notes that MPMs constitute "a new concept that is different and narrower in scope than non-GAAP measures found in the management discussion and analysis section of the annual report."
The practical implication: your IR team's adjusted EBITDA definition, which may have evolved organically over several years, will now be stress-tested by your auditor. Inconsistencies between how you describe the measure in earnings releases and how it reconciles to IFRS subtotals will surface in the audit. Start that review now, not in Q4 2026.

The Retrospective Restatement Problem: Explaining the Numbers to Investors
IFRS 18 is applied retrospectively. For a December year-end company, the 2027 annual report must show restated 2026 comparatives under the new framework. That means the 2026 operating profit figure that appears in the 2027 annual report will likely differ from the 2026 operating profit figure you reported in your 2026 annual report under IAS 1.
This is not a restatement due to an error. But analysts and investors who are not expecting it will treat it as one unless you get ahead of it.
The communication sequence that works:
-
2025 annual report (or 2026 interim reports): Include a qualitative disclosure that IFRS 18 will be adopted for periods beginning 1 January 2027, with a description of the expected impact on income statement structure and key subtotals. Name the categories of items expected to be reclassified. Quantification is not required at this stage but is increasingly expected by sophisticated investor bases.
-
2026 annual report: Provide a quantified estimate of the expected reclassification impact on operating profit and the other new subtotals. This is the last set of IAS 1 financial statements. Use the narrative section to walk investors through the bridge from IAS 1 operating profit to the expected IFRS 18 operating profit for the same period.
-
Q1 2027 earnings call (or equivalent): Present results under IFRS 18 for the first time. Have a one-page bridge ready showing the 2026 restated comparatives versus the 2026 IAS 1 figures, with each reclassification item explained. Anticipate analyst questions about why operating profit changed.
-
2027 annual report: Include a full reconciliation of the opening balance sheet and comparative period income statement in the transition note, as required by IFRS 18's retrospective application requirements.
FTI Consulting notes that IFRS 18 "raises scrutiny and reputational risks for listed companies" precisely because the standardisation of operating profit enables cross-company comparison in a way that was not possible under IAS 1. Companies whose restated figures differ materially from their previously communicated non-GAAP measures will face the most scrutiny.
Updating Earnings Releases, Investor Presentations, and Analyst Briefing Materials
The reclassification work in the accounting team feeds directly into the IR team's materials. These need updating before the first IFRS 18 reporting period.
Earnings release template: Replace the IAS 1 income statement structure with the five-category structure. Add the two new mandatory subtotals. If you currently lead with an adjusted EBITDA or adjusted operating profit figure, confirm whether it qualifies as an MPM and, if so, ensure the reconciliation in the release is consistent with the MPM note in the financial statements.
Investor presentation: Update the historical financial summary tables. If you show five years of operating profit history, the 2026 and earlier figures will need to be presented on a comparable basis or clearly labelled as IAS 1 figures. Mixing IAS 1 and IFRS 18 operating profit in the same chart without explanation is a significant investor communication risk.
Analyst model support: Consider publishing a bridging document specifically for sell-side analysts, showing the restatement of key historical periods under IFRS 18. Analysts who cover multiple companies in your sector will be rebuilding their models when IFRS 18 hits. Companies that make this easy build goodwill; companies that leave analysts to figure it out invite model errors and downward revisions.
Earnings call scripts: Prepare a standard explanation of the IFRS 18 transition for the first two or three calls after adoption. The CFO and IR head should be aligned on the language. The explanation should be factual and brief: what changed in presentation, what did not change in the underlying business, and where to find the reconciliation.
The Audit Dimension: What Changes When MPMs Enter the Financial Statements
Under IAS 1, adjusted metrics in earnings releases and investor presentations sat outside the audited financial statements. Auditors had no formal responsibility for them, though they would typically read them for consistency with the audited numbers.
Under IFRS 18, the MPM reconciliation note is inside the financial statements. It is audited. This has three practical consequences:
-
The definition of each MPM must be precise and consistent. Auditors will test whether the measure used in the earnings release matches the measure reconciled in the note. Vague or evolving definitions will not survive.
-
The tax and NCI effects must be calculated and disclosed. This requires finance teams to work through the tax impact of each reconciling adjustment, which is often more complex than the adjustment itself.
-
Changes to MPM definitions between periods require disclosure and explanation. If you change how you calculate adjusted EBITDA, that change will be visible in the audited note. Investors and regulators will notice.
Start the MPM governance review now. Identify every non-GAAP measure of profit or loss that appears in your public communications. Assess whether it meets the IFRS 18 MPM definition. For those that do, draft the reconciliation and have it reviewed by your auditor before the 2027 effective date.

Implementation Timeline: When to Do What
The retrospective restatement requirement means the reclassification analysis must be substantially complete well before the first IFRS 18 reporting period. Working backwards from a December year-end:
| Milestone | Target date | What it involves |
|---|---|---|
| Main business activities judgment documented | Q2 2026 | Board/audit committee sign-off on the classification framework |
| Full reclassification analysis complete | Q3 2026 | Every P&L line item mapped to the five categories; system changes scoped |
| 2026 annual report transition disclosure | Q1 2027 | Quantified estimate of reclassification impact on key subtotals |
| MPM definitions finalised and auditor-reviewed | Q3 2026 | Consistent with what will appear in the 2027 MPM note |
| Earnings release and IR templates updated | Q4 2026 | Ready for first use in Q1 2027 results |
| Analyst bridging document prepared | Q1 2027 | Published alongside or shortly after the 2027 annual report |
| First IFRS 18 annual report filed | 2027 | Includes restated 2026 comparatives and full transition note |
As EY's IFRS 18 team notes, "the project plan needs to allow sufficient time for the necessary analysis, which is often a key success factor of the project. Companies need to allow time and resources for additional accounting issues to be resolved that were not included in the original [implementation plan]."
Early adoption is permitted from April 2024. Companies with sophisticated investor bases or those seeking to differentiate their reporting quality may consider it, though they must disclose the early adoption in the notes.
FAQ
What is the difference between a reclassifying adjustment under IFRS 18 and a prior-period error restatement? A reclassification under IFRS 18 is a change in presentation required by a new standard, applied retrospectively under IAS 8. It is not a correction of an error. The underlying recognition and measurement of income and expenses does not change. Investors and analysts should understand this distinction, and your transition disclosures should make it explicit.
Which items are never reclassified to profit or loss under IFRS 18? IFRS 18 governs classification within the statement of profit or loss. Items recognised in other comprehensive income (OCI) remain in OCI; the standard does not change the reclassification-to-profit-or-loss rules for OCI items, which are governed by the relevant measurement standards (e.g. IFRS 9, IAS 19).
Do we need to restate comparatives, and how far back? Yes. IFRS 18 requires retrospective application, which means restating the comparative period presented in the first IFRS 18 annual report. For a December year-end, that is the 2026 comparative in the 2027 annual report. You are not required to restate periods beyond the comparative year, though you may choose to present a longer restated series for investor communication purposes.
What are the key changes in IFRS 18 that affect investor communication specifically? Three changes drive the investor communication challenge: (1) the mandatory operating profit subtotal, defined by the standard rather than management, which may differ materially from the operating profit figure companies have historically reported; (2) the MPM disclosure note, which brings non-GAAP measures into the audited financial statements for the first time; and (3) the retrospective restatement requirement, which means historical comparatives will look different in the 2027 annual report.
How does IFRS 18 interact with ESMA's Alternative Performance Measures guidelines for EU-listed companies? EU-listed companies already comply with ESMA's APM Guidelines, which require labelling, definitions, and reconciliations for non-GAAP measures in regulated information. IFRS 18's MPM requirements overlap with but are narrower than the ESMA APM framework. MPMs are a subset of APMs: only measures of profit, loss, or subtotals thereof that appear in public communications qualify. Companies will need to map their existing APM disclosures against the IFRS 18 MPM definition and manage both frameworks simultaneously.
What is the journal entry for a reclassification adjustment under IFRS 18? IFRS 18 reclassifications are presentation changes, not accounting entries that affect retained earnings or net assets. The adjustment is made by restating the comparative income statement to show items in their new categories. No debit/credit entry changes the balance sheet. The transition note in the 2027 annual report explains the restatement.
