White Collar Criminal & Federal Defense Attorneys Trusted Nationwide
Allegations involving the Public Company Accounting Oversight Board (PCAOB) are never routine. They place the credibility, licenses, and future of accounting firms and individual auditors squarely at risk. PCAOB matters strike at the core of public trust in financial reporting—and when scrutiny begins, the consequences can be swift, public, and career-defining.
The PCAOB was created to oversee audits of public companies and protect investors. When it initiates an inquiry or enforcement action, the allegations often involve claims of audit failures, independence violations, or misconduct during inspections or investigations. These cases frequently escalate into high-stakes regulatory battles, exposing firms and professionals to substantial penalties and reputational harm.
At Chapman, Dowling & Mallek, we treat PCAOB matters for what they are: existential threats that demand immediate, strategic, and highly experienced defense.
From a legal standpoint, PCAOB defense is not simply about responding to allegations. It is about controlling risk, shaping the narrative, and protecting professional standing at every stage of the process.

This requires navigating a dense framework of auditing standards, securities laws, and administrative procedures—often alongside parallel inquiries by other regulators.

These investigations often do not occur in isolation. The PCAOB frequently coordinates with:
This layered enforcement environment significantly raises the stakes and underscores the need for coordinated legal strategy.
PCAOB sanctions are designed to be punitive and deterrent. They can permanently alter careers and dismantle firms. Penalties may include:
Defending PCAOB matters requires command of the laws and rules governing audit oversight, including:
