For nearly two decades, discussions around financial reporting have mostly focused on accounting standards. But with IFRS-18, the focus shifts beyond reporting rules. It now meets growing demands for transparency and useful disclosures for decisions.
The standard itself is not the fundamental shift. In the new era investors no longer want more information, they just want more comparable information.
And that is why Europe is entering the new era of financial reporting.
When the IASB finalized this standard, its former Chair, Andreas Barckow, called it the biggest change in presentation.
He said it was the biggest change since IFRS Accounting Standards began over two decades ago. That’s not corporate speak it’s a direct signal of how differently Europe’s annual reports will look from 2027 onward.
Two Companies. Same Profits. Two Completely Different Stories.
Consider this scenario, you are an investor reviewing the annual reports of two European manufacturing companies. Both generated nearly identical revenues and similar profits.
But one company reports its performance in a different way, using its own adjusted metrics. It also groups expenses very differently than the other company.
Both are correct in their ways of presenting information, both comply with IAS 1. But evaluating both feels like reading two books written in different languages.
One of the most notable shortcomings of IAS 1 is not the compliance issue, it is comparability. Investors often struggle to understand which company’s financial performance mirrored the underlying business performance because each organization had significant flexibility in presenting results. Hence, the organization adopted IFRS 18.
When flexibility Met Investor Expectations
IAS 1 offered flexibility to companies in presenting financial reporting, but investors demanded consistency and comparability; those expectations outweigh the standard.
As organizations used adjusted profit measures more often, they also used custom income statement formats and management-defined KPIs.
This made it harder to compare companies.
It was even hard to compare companies within the same industry.
As a result, investors relied more on management’s interpretation than on a standardized reporting format. Europe’s response to this challenge is IFRS 18.
The focus of IFRS 18 shifts away from how companies account for transactions.
It changes how financial performance is presented, structured, and explained.
This leads to more consistent financial reporting.
It does not change the underlying accounting principles.
Five Moments that will change every Annual Report
When IFRS 18 was established, it introduced several technical updates, five changes will reshape how companies communicate with investors.
Operating Profit Gets a Common Definition:
Companies will be presenting a standardized operating profit subtotal for the first time; it’s a landmark move.
Rather than having different interpretations across industries, investors wanted a clearer view of operational performance. This helped them compare businesses more consistently.
The IASB did not make this call in a vacuum. In its review of 100 companies, it found that over 60 reported an “operating profit” figure.
They calculated these figures in at least nine different ways. Nine different answers to what should be the same question. IFRS 18 eliminates that exact confusion.
Management Performance Measures Must tell their Full Story:
This is likely the biggest change. In the past, many European companies reported metrics like Adjusted EBITDA, Adjusted Operating Profit, or Adjusted EPS. Under IFRS 18, these metrics do not disappear they become more transparent.
Now companies must show how they calculated management-defined performance measures. They must also reconcile these measures to IFRS figures in the financial statements.
The conversation shifts from
“Trust us.” to “Here’s the evidence.”
As the Journal of Accountancy has emphasized, the real risk with IFRS 18 isn’t the rule itself, it’s the execution. If a company’s adjusted numbers don’t reconcile cleanly to its audited figures, investor confidence erodes fast. The standard does not just ask companies to show their math, it makes sure that math holds up.
Material Information Steps into the Spotlight
IFRS 18 introduces stronger principes around aggregation and disaggregation. Earlier, companies could combine many expenses. Now, the guidelines encourage companies to list them clearly instead.
The objective was to give investors more insight into where the company spent money.
Standardized Income Statements
Under IAS 1, companies would organize income and expenses in different ways. Now all companies will follow a clearer, more consistent structure. They will organize information into categories like Operating, Investing, and Financing. This makes financial statements easier to compare.
Financial Statements tell you what happened. Notes tell you why
The biggest shift from IFRS 18 is not a new line item. It is a new way to think about financial reporting.
The primary financial statements provide structured summary of a company’s performance. The notes provide the explanation behind the performance.
Together they provide a holistic view of company’s financial performance and position. Rather than treating it as an appendix, IFRS 18 reinforces its role as essential part of investor communication.
The Real work Starts after Financial Finishes
Initially, IFRS 18 looks like any other accounting standard. It transforms the entire reporting process.
Once the Finance teams updates statements, the work does not stop there:
- Legal reviews the disclosures to ensure they are accurate and compliant.
- Investor Relations updates the presentations and communications for shareholder and analysis
- Auditors verify that the revised disclosures meet reporting requirements.
- Compliance checks that the reports are consistent with regulatory expectations.
- Management reassesses how it measures and communicates business performance.
- ESG teams align sustainability disclosures with the updated financial information.
What seems like a change in accounting standards becomes an organization-wide reporting effort. Many teams work together to deliver compliant disclosures.
This cross-functional scramble is already visible in the numbers. A 2025 survey asked more than 2,600 finance professionals.
It found that about 80% of companies that use IFRS Standards had not started an IFRS 18 project. These include financial penalties and audit issues. They can also face reporting complications and operational disruption.
Most damaging, they may lose investor confidence. IFRS 18 Doesn’t Create More Reporting. It Creates Better Reporting.
A common misconception is that IFRS 18 requires companies to prepare entirely new reports.
It will not.
The financial data already exists. The real challenge is keeping that information consistent across annual reports, investor presentations, press releases, websites, and regulatory filings.
This is where disclosure management helps organizations. It helps organizations deliver consistent reports. It also makes the transition to IFRS 18 more efficient.
The Future Belongs to Comparable Companies
Twenty years ago, compliance was the benchmark.
Today comparability builds confidence.
IFRS 18 is not replacing IAS 1 it is basically evolving because of the expectations of investors have changed.
One advisory firm, put it plainly. Boards and executives should treat IFRS 18 as a shift in market communication. It is not just a compliance exercise. It will shape how investor’s view performance, spot trends, and compare a company with its peers, ready or not.
Companies that embrace this shift will not simply meet another reporting requirement.
They will share their results more clearly, explain their numbers with more confidence, and build stronger trust with key people.
Because in today’s capital markets, great reporting is not just about getting the numbers right.
It’s about making sure everyone understands the story those numbers are telling
The Journey Changes Less Than You Think
At first glance, IFRS 18 may feel like a significant shift. In reality, it is an evolution in how companies present and explain financial performance. This is not a complete overhaul of the reporting process.
Organizations that use a well-structured disclosure management approach already can adapt.
A practical reason this can’t wait until 2027 exists, either. Because IFRS 18 applies retrospectively, the company will need to restate the 2026 figures to match the new structure. Deloitte warns that companies treating this as a year-end task may face incomplete data.
They may also face system gaps and weak comparisons.
By keeping financial data, narratives, and disclosures connected all year, they can respond to new requirements.
They can do so without losing momentum or confidence.
Because reporting will continue to evolve. A connected disclosure process ensures your reporting journey evolves with them not against them.
Frequently Asked Questions About IFRS 18
What is IFRS 18?
IFRS 18 is the new accounting standard from the IASB that replaces IAS 1. It explains how companies must format their income statement and report their financial performance. It aims to make results easier to compare across companies.
When does IFRS 18 become effective?
IFRS 18 applies to annual reporting periods beginning on or after 1 January 2027. Companies may adopt it early, provided they disclose their early adoption.
Does IFRS 18 replace IAS 1 completely?
Yes. IFRS 18 fully replaces IAS 1. Many general principles remain. Examples include going concern and current or non-current classification. These are largely unchanged.
Does IFRS 18 change how companies calculate profit?
No. IFRS 18 does not change how entities recognize or measure income and expenses. Total profit or loss for the period stays the same. What changes is how people present, categorize, and explain that performance.
What are Management-Defined Performance Measures (MPMs)?
MPMs are adjusted metrics, like adjusted EBITDA or underlying profit, that companies use in public communications. Under IFRS 18, companies must now disclose these measures in audited financial statements. You must reconcile them to the closest IFRS-defined subtotal.
What are the two new mandatory subtotals in IFRS 18?
Companies must now present operating profit or loss and profit or loss before financing and income tax. These give investors consistent reference points that did not exist under IAS 1.
Will IFRS 18 affect the statement of cash flows?
Yes. IFRS 18 makes consequential changes to IAS 7, including removing the choice in how interest and dividends paid or received are classified, and requiring the cash flow reconciliation to start from operating profit.
Do companies need to restate prior-year figures?
Yes. IFRS 18 must be applied retrospectively. Companies adopting it for the 2027 financial year must restate 2026 comparative figures. They must do this under the new presentation requirements.
How can companies prepare for IFRS 18 now?
Early preparation often includes mapping current income statement items to the new categories. It also includes identifying which metrics qualify as MPMs. Adopt a connected disclosure management process. This keep data, tagging, and reporting aligned during the transition.
