Acquisition Accounting in Australia: What to Know for 2026

For Australian businesses considering mergers, acquisitions, or restructures in 2026, acquisition accounting remains a critical process. Recent regulatory changes mean companies must pay close attention to how they recognise, value, and disclose acquired assets and liabilities. Getting this process right is essential—not just for compliance, but for maintaining transparency and investor confidence.

This article explains what acquisition accounting involves, outlines the latest regulatory updates for 2026, and provides practical guidance for businesses navigating these changes.

Acquisition accounting, sometimes called purchase price allocation, is the process of combining the financial statements of an acquired business with those of the acquirer. In Australia, this process is governed by the Australian Accounting Standards Board (AASB) and is aligned with International Financial Reporting Standards (IFRS).

Key steps in acquisition accounting include:

• Identifying and valuing assets and liabilities: All assets and liabilities of the acquired business must be measured at fair value as of the acquisition date.
• Recognising intangible assets: Intangible assets such as intellectual property, customer relationships, and brand value are identified and valued separately from goodwill.
• Calculating goodwill: Goodwill is the excess of the purchase price over the net fair value of identifiable assets and liabilities.

Acquisition accounting directly affects reported profits, future amortisation expenses, and can influence how investors perceive the company’s financial health.

Accurate acquisition accounting is essential for several reasons:

• Regulatory compliance: Australian businesses must follow AASB and IFRS requirements when reporting acquisitions.
• Investor trust: Transparent reporting helps maintain investor confidence, especially when significant assets or liabilities are involved.
• Strategic decision-making: Proper valuation and disclosure can impact future business decisions, tax outcomes, and financial planning.

In 2026, the AASB has introduced updates that reflect changes in international standards. These updates are designed to improve transparency and ensure that acquisition accounting provides a clear and accurate picture of a company’s financial position.

Key Changes for 2026

• Intangible asset recognition: Digital assets, including software and data sets, must be assessed and valued individually rather than grouped into goodwill.
• Enhanced disclosure requirements: Companies are now required to provide more detailed breakdowns of purchase price allocations, including the methodologies and key assumptions used in fair value assessments.
• Contingent consideration treatment: Payments linked to future performance (such as earn-outs) must be measured at fair value at the acquisition date. Subsequent changes in value are recognised in profit or loss, rather than only on the balance sheet.

These changes aim to provide clearer information to investors and regulators, and to reduce the risk of aggressive accounting practices.

Navigating acquisition accounting in 2026 requires careful planning and collaboration across teams. Here are some practical steps to help ensure a smooth process:

1. Engage Experts Early

Involve independent valuation specialists early in the acquisition process. This is especially important for valuing intangible and digital assets, which now require more detailed assessment.

2. Conduct Scenario Analysis

Model different performance outcomes for contingent payments and earn-outs. This helps anticipate how changes in value could affect future profit and loss statements.

3. Integrate Due Diligence

Coordinate financial, tax, and legal due diligence teams from the outset. This approach helps identify hidden liabilities or overlooked assets, such as pending legal matters or unregistered intellectual property.

4. Communicate Transparently

Use clear, straightforward language in financial statements and investor communications. Explain significant accounting judgments and their impacts to help stakeholders understand the financial implications of the acquisition.

The evolving regulatory environment presents both challenges and opportunities for Australian businesses involved in mergers and acquisitions.

Challenges

• Valuing new types of assets: Rapidly changing technology means businesses may need to value assets like software, data, or intellectual property that did not previously require separate assessment.
• Meeting disclosure requirements: Enhanced disclosure rules require more detailed reporting, which can increase the complexity of financial statements.

Opportunities

• Building market confidence: Transparent and disciplined acquisition accounting can strengthen investor trust and support share price stability.
• Leveraging technology: New valuation tools and analytics can improve the accuracy and efficiency of the acquisition accounting process.

What is the main purpose of acquisition accounting?

Acquisition accounting ensures that the financial statements of the acquiring business accurately reflect the fair value of assets and liabilities acquired in a merger or acquisition.

How are digital assets treated under the 2026 rules?

Digital assets, such as software and data sets, must be individually identified and valued, rather than being included in goodwill.

What are contingent considerations?

Contingent considerations are payments that depend on the future performance of the acquired business. Under the 2026 rules, these must be recognised at fair value at the acquisition date, with changes in value affecting profit or loss.

Why is transparent communication important in acquisition accounting?

Clear communication helps investors and stakeholders understand the financial impact of an acquisition and the judgments made in valuing assets and liabilities.

Australian businesses planning mergers or acquisitions in 2026 should stay informed about regulatory updates and adapt their processes accordingly. Early engagement with valuation experts, thorough due diligence, and transparent communication are key to successful acquisition accounting. By focusing on these areas, companies can meet compliance requirements and build stronger relationships with investors and stakeholders.
