For finance leaders in the Kingdom of Saudi Arabia, preparing for IFRS 18 adoption requires more than changing the format of the income statement. Organizations should reassess the reporting metrics used by management, boards, investors, lenders, and other stakeholders to ensure that performance measures remain consistent, transparent, and supportable. IFRS Consulting Services KSA can help finance teams review existing reporting structures, identify classification issues, and establish controls before the new requirements become mandatory. IFRS 18 will apply for annual reporting periods beginning on or after 1 January 2027, while early adoption is permitted.
Why Reporting Metrics Need Review Before IFRS 18
IFRS 18 introduces significant changes to how financial performance is presented and disclosed. The standard replaces IAS 1 and introduces defined subtotals, new requirements for management defined performance measures, and stronger principles for aggregation and disaggregation. Importantly, IFRS 18 primarily changes presentation and disclosure rather than the underlying recognition and measurement of transactions.
For organizations operating in KSA, the transition is particularly relevant because listed entities have been permitted to adopt IFRS 18 early during 2026, while mandatory application begins in 2027. This creates an important preparation window for finance departments to test reporting models, validate historical information, and review performance metrics before mandatory implementation.
A metric that has been useful internally may require a different presentation or additional explanation under IFRS 18. Therefore, management should not wait until the first IFRS 18 financial statements are being prepared. The review should begin with the metrics most frequently used in monthly management reports, investor communications, budgets, forecasts, and board presentations.
1. Operating Profit Margin
Operating profit margin is one of the most important metrics requiring review because IFRS 18 introduces operating profit or loss as a defined subtotal.
The metric is generally calculated by dividing operating profit by revenue. However, the composition of operating profit may change because IFRS 18 introduces defined categories for operating, investing, and financing income and expenses.
Finance teams should therefore compare their existing operating profit calculation with the classification requirements under IFRS 18. Items historically treated as operating may need reassessment depending on their nature and the entity’s main business activities.
For example, an organization may currently calculate operating margin using a management specific definition that excludes certain costs. Under IFRS 18, the statutory operating profit subtotal will follow the requirements of the new standard. Management should determine whether internal operating margin calculations reconcile clearly to the new statutory presentation.
A useful readiness test is to calculate the current operating margin and the expected IFRS 18 operating margin for at least 12 months of historical data. Any material variance should be documented and explained.
2. EBITDA and Adjusted EBITDA
EBITDA remains widely used by management and financial statement users, but IFRS 18 increases the importance of understanding how such measures are constructed and communicated.
If EBITDA or adjusted EBITDA is used in public communications and meets the definition of a management defined performance measure, additional disclosures may be required. IFRS 18 requires entities to provide information that helps users understand what such measures communicate and how they compare with measures defined by IFRS Accounting Standards.
This means finance teams should review every adjustment applied to EBITDA. Common adjustments may include restructuring expenses, acquisition related costs, unusual legal expenses, impairment charges, or other items considered exceptional by management.
The review should establish a documented definition, calculation methodology, reconciliation process, and approval framework.
Management should also examine whether terms such as recurring, exceptional, non recurring, or adjusted are clearly defined. IFRS 18 requires management-defined performance measures to be labelled and described in a manner that faithfully represents their characteristics and does not mislead users.
3. Net Finance Result
The net finance result is another metric that deserves detailed analysis before adoption.
IFRS 18 introduces specific requirements for classifying income and expenses between operating, investing, and financing categories. The classification can depend on the entity’s main business activities, making the assessment more important for groups operating across different business models.
Finance teams should identify all interest income, interest expense, financing related costs, foreign exchange effects, and other relevant financial items. Each item should be mapped against the IFRS 18 classification requirements.
This exercise can reveal differences between statutory reporting and internal management reporting. A metric that currently combines financing and operating effects may need to be separated to provide clearer insight into operating performance.
The review should also consider whether existing dashboards, financial models, and management packs can generate the required information consistently.
4. Profit Before Tax and Financing Measures
Profit before tax remains a critical measure for stakeholders, but IFRS 18 introduces another defined subtotal, profit or loss before financing and income taxes.
This creates an opportunity for organizations to reassess how they communicate underlying performance before financing decisions and taxation effects.
Finance departments should calculate the expected IFRS 18 subtotal using historical information and compare it with current internal measures. The objective should be to identify differences caused by classification rather than changes in economic performance.
For KSA organizations, this analysis can also strengthen communication between financial reporting teams and senior management. When management understands exactly why a subtotal changes under the new standard, it becomes easier to explain variations to boards, investors, lenders, and other stakeholders.
A practical review should cover at least 3 reporting layers: statutory financial statements, management reporting, and external communications.
5. Revenue Growth and Operating Expense Ratios
Revenue growth itself may not change because of IFRS 18, but the way revenue is presented alongside operating expenses can affect how users interpret performance.
IFRS 18 introduces requirements concerning aggregation and disaggregation and requires entities to present operating expenses in a way that provides the most useful structured summary. Depending on the circumstances, expenses may be presented by nature, by function, or using a mixed presentation.
Consequently, metrics such as revenue growth, personnel cost as a percentage of revenue, selling expense ratio, administrative expense ratio, and cost of sales ratio should be reviewed alongside the new presentation structure.
The key question is whether the underlying data can support the desired level of disaggregation.
Organizations should test whether their accounting systems can trace significant expense balances to the appropriate categories and line items. This may require changes to account mappings, reporting hierarchies, cost centre structures, and consolidation processes.
6. Management Defined Performance Measures
Management defined performance measures deserve particular attention because IFRS 18 introduces specific disclosure requirements around these measures.
A subtotal can qualify as a management defined performance measure when it is used in public communications outside financial statements, communicates management’s view of an aspect of the entity’s financial performance as a whole, and is not specifically required by IFRS Accounting Standards or otherwise excluded from the definition.
This means organizations should create an inventory of performance measures appearing in annual reports, presentations, earnings communications, websites, management reports, and other public materials.
A useful review can identify approximately 20 to 30 commonly used performance measures in a complex reporting environment, although the actual number varies significantly by organization.
Each measure should have an owner, documented formula, source data, reconciliation to IFRS figures, approval process, and consistent terminology.
This is an area where IFRS Consulting Services KSA can support finance functions by helping establish a controlled MPM framework and documenting the relationship between management reporting and statutory reporting.
7. Cash Flow and Free Cash Flow Metrics
Free cash flow is another important management metric that should be reviewed even though IFRS 18 primarily addresses presentation and disclosure in the financial statements.
Management should determine whether free cash flow calculations consistently reconcile with operating cash flows, capital expenditure, and other adjustments. Different departments sometimes use different definitions, creating inconsistencies between board reporting, budgeting, treasury analysis, and external communications.
Before IFRS 18 adoption, finance teams should establish one documented definition for every externally communicated cash flow performance measure.
The review should also identify whether the metric is used publicly and whether it could fall within the scope of management defined performance measure disclosures.
A robust reconciliation should show the starting IFRS figure, each adjustment, the final management metric, and the rationale for every adjustment.
2026 IFRS 18 Readiness Figures for KSA Organizations
The timing of preparation is now particularly important. In 2026, listed joint stock companies on the Saudi Exchange received the ability to early adopt IFRS 18, while mandatory application starts for financial periods beginning on or after 1 January 2027. Organizations choosing early adoption must continue meeting the applicable statutory reporting requirements and disclose the effects of early adoption through the prescribed channels.
The global implementation timeline also shows that IFRS 18 is not simply a presentation exercise. Current 2026 implementation guidance highlights data, systems, internal controls, management performance measures, and auditor engagement as important implementation areas.
For practical planning, organizations can use a 4 phase readiness model:
Phase 1: Inventory existing reporting metrics.
Phase 2: Map metrics and income statement items to IFRS 18 requirements.
Phase 3: Test historical data and prepare comparative information.
Phase 4: Implement controls, reporting templates, and governance.
Beginning this process in 2026 gives finance teams several months to identify gaps before the mandatory reporting period begins.
Building an IFRS 18 Metric Review Framework
A structured review should begin with a complete inventory of financial metrics. The inventory should capture where each metric appears, who owns it, how it is calculated, which data sources support it, and whether it is communicated externally.
The next step is classification. Finance teams should determine whether each measure is an IFRS defined subtotal, a management defined performance measure, an internal management metric, or another type of performance indicator.
Data lineage should then be documented. Every major metric should be traceable from the general ledger or source system through reporting calculations to the final published figure.
Controls are equally important. Organizations should establish review procedures covering calculation accuracy, consistency, reconciliation, approval, and changes to definitions.
Finally, management should conduct a dry run using comparative information. IFRS 18 requires retrospective application, making prior period information a central part of implementation planning.
Why Data Quality Matters for IFRS 18
The quality of IFRS 18 reporting will depend heavily on the quality and granularity of underlying financial data.
If expenses are stored only at highly aggregated levels, finance teams may struggle to produce the required presentation. Similarly, if management metrics are calculated manually across spreadsheets, reconciliation and auditability can become difficult.
A useful target is to achieve 100% documented ownership for material reporting metrics before the first IFRS 18 reporting cycle.
Finance teams should also aim for automated reconciliation wherever practical. Manual calculations increase the risk of inconsistent definitions, formula errors, and unexplained differences between internal and external reporting.
The 2026 implementation period therefore provides an opportunity to modernize reporting architecture rather than simply modify financial statement templates.
Strengthening Governance Before Adoption
IFRS 18 implementation should involve finance, accounting, internal audit, tax, treasury, investor relations, information technology, and senior management where relevant.
Governance should answer five fundamental questions:
Who owns each metric?
What is the approved definition?
Which source systems provide the data?
How is the calculation reconciled?
Who approves changes?
A formal reporting metric register can provide a central source of truth. This register should be reviewed periodically and updated whenever management changes the definition or presentation of a performance measure.
IFRS Consulting Services KSA can also assist organizations in developing documentation, classification frameworks, metric inventories, reconciliation methodologies, and IFRS 18 implementation controls tailored to their reporting environment.
Preparing for the 2027 Reporting Cycle
The most effective approach is to treat IFRS 18 readiness as a reporting transformation project rather than a last minute accounting adjustment.
During 2026, organizations should complete their metric inventory, test classifications, assess management defined performance measures, review expense presentation, evaluate data availability, and perform comparative reporting simulations.
The seven metrics discussed above provide a practical starting point:
Operating profit margin
EBITDA and adjusted EBITDA
Net finance result
Profit before tax and financing measures
Revenue growth and operating expense ratios
Management defined performance measures
Cash flow and free cash flow metrics
Reviewing these measures early can expose inconsistencies before they reach published financial statements.
Final Preparation Priorities for KSA Finance Teams
For organizations preparing for IFRS 18 in KSA, the priority should be clarity, consistency, traceability, and governance.
The 2026 early adoption opportunity provides a valuable testing period before mandatory application from 1 January 2027. Organizations should use this period to compare existing metrics with IFRS 18 requirements, validate classifications, strengthen data structures, and establish repeatable controls.
Most importantly, finance teams should not assume that familiar management metrics will automatically remain appropriate under the new reporting environment. Each significant metric should be assessed based on its definition, calculation, purpose, source data, external use, and relationship with IFRS defined subtotals.
A disciplined metric review can help reduce reporting surprises, improve stakeholder understanding, and create a stronger foundation for IFRS 18 implementation. IFRS Consulting Services KSA can provide additional support for organizations seeking structured readiness assessments, metric reviews, disclosure analysis, and implementation planning.
