Are there any public company audit practices that focus on listed entity assurance for complex reporting?

Yes. In public-company audit practice, there are several assurance approaches and specializations that focus specifically on listed-entity assurance and complex reporting.

Common examples include:

• Listed entity audits under PCAOB/ISA standards
  Audits of companies listed on public exchanges require enhanced procedures, documentation, and partner scrutiny because of investor-facing reporting risk.

• Integrated audits of financial statements and internal control over financial reporting (ICFR)
  Especially in the U.S., public company auditors often perform both the financial statement audit and an audit of ICFR under PCAOB AS 2201, which is designed for complex public-company reporting environments.

• Complex accounting and disclosure audits
  These focus on areas like:

  • revenue recognition
  • fair value measurements
  • derivatives and hedging
  • consolidation and VIEs
  • goodwill impairment
  • tax provisions
  • segment reporting
  • share-based compensation
  • non-GAAP and other market disclosures

• Group / multinational audits
  For listed companies with many subsidiaries or cross-border operations, auditors use group-audit approaches to coordinate work across component auditors and manage complex consolidation reporting.

• Special-purpose assurance engagements
  These may cover:

  • pro forma information
  • compliance certificates
  • regulatory filings
  • sustainability/ESG disclosures
  • controls over nonfinancial reporting

• Continuous audit / data-analytics-enabled assurance
  Some firms use advanced analytics, automation, and risk-focused testing to handle high-volume, complex public-company reporting.

If you mean a specific firm or service line, examples in practice are often described as “public company assurance,” “listed entity audits,” “capital markets,” or “complex accounting advisory and assurance.”
