Do you trust accounting firms to catch problems in the companies they audit?
The Public Company Accounting Oversight Board ordered Macias Gini & O'Connell LLP to pay a $500,000 penalty for violating auditing and quality control standards. The order centers on two audits of a California biotech company that later declared Chapter 11 bankruptcy.
Why it matters
The order signals that the PCAOB is scrutinizing how auditors evaluate going concern doubts and goodwill impairment in the period before a company fails. Separately, notices issued to 97 registered audit firms put a compliance deadline on a much broader group of auditors.
The penalty is $500,000, and the PCAOB sent delinquency and impending withdrawal notices to 97 registered audit firms, with a compliance deadline of March 1, 2027. The order does not indicate whether MGO intends to appeal the penalty.
The players
Public Company Accounting Oversight Board (PCAOB)
The nonprofit regulator created by the Sarbanes-Oxley Act of 2002 that oversees audits of public companies and enforces auditing standards.
Macias Gini & O'Connell LLP
A Los Angeles-based accounting and audit firm that was penalized in the PCAOB order over its audits of a bankrupt biotech company.
The details
The PCAOB found that MGO's engagement team failed to properly evaluate a biotech company's intangible assets and goodwill in a fiscal 2021 audit, and failed to adequately assess the company's ability to continue as a going concern. MGO's national office provided consultation memos that concurred with the engagement team, yet the firm still issued an unqualified opinion on the company's fiscal 2022 statements without a going concern paragraph.
Timeline
Fiscal year 2021: MGO audit of the biotech company's intangible assets and goodwill.
Fiscal year 2022: Unqualified audit opinion issued on the company's financial statements.
August 2023: The biotech company declared Chapter 11 bankruptcy.
November 3, 2026: PCAOB issued the enforcement order against MGO.
March 1, 2027: Compliance deadline for the 97 firms receiving notices.
Market Landscape
The PCAOB's authority to police public company audits traces to the Sarbanes-Oxley Act of 2002, which created the board after the Enron and WorldCom collapses. This order applies that mandate to going concern and goodwill judgments that auditors make before a company fails.
Investors in public companies audited by firms on the PCAOB's list may want to check whether their auditor has received a notice or is still in good standing. The case also shows that a clean audit opinion can be challenged after a company's collapse, which matters for anyone relying on audited financial statements.
The takeaway
Auditor oversight is tightening, and a clean opinion issued shortly before a bankruptcy can draw regulatory scrutiny years later. Readers evaluating a public company should pay attention to going concern language and goodwill write-downs in its financial statements.
What happens next
Firms that received delinquency and impending withdrawal notices must regain compliance with PCAOB requirements by March 1, 2027, or face withdrawal of their registration.
