Industry Context

Changes in independent auditors are a routine part of corporate governance, often occurring due to auditor rotation policies, competitive bidding, or strategic decisions by either the company or the auditing firm. The transition from KPMG to EY, both 'Big Four' firms, is a common occurrence in the industry and typically does not signal underlying financial distress unless accompanied by disagreements or restatements, which are explicitly absent here.

Comparison to Industry Standards

• The transition from one 'Big Four' accounting firm (KPMG) to another (EY) is a standard practice among publicly traded companies, often driven by audit committee policies on auditor rotation or competitive tender processes.
• The explicit statement that there were no disagreements or reportable events with the former auditor, KPMG, aligns with best practices for transparent auditor changes and is a positive indicator compared to situations where such changes are prompted by disputes over financial reporting.

Corporate Governance

Stakeholder Impact

• Shareholders: The change was approved by shareholders, ensuring their interests in transparent financial reporting are maintained.
• Investors: Provides clarity on the company's financial oversight, with a reputable firm taking over audit responsibilities, which can instill confidence.

Next Steps

• Ernst & Young LLP will serve as the independent registered public accounting firm for Aptose Biosciences Inc. for the fiscal year ending December 31, 2025.

Key Dates

Recommendation

This filing details a routine change in the company's independent auditor, with no reported disagreements or adverse events. While important for corporate governance, it does not present new financial information or strategic developments that would significantly alter the company's valuation or investment thesis. Therefore, a 'hold' recommendation is appropriate as this event alone does not warrant a change in investment position.
