PCAOB Flags 97 Audit Firms for Withdrawal: Is Your Auditor on the List?

The PCAOB just published a list of 97 audit firms that could lose their registration on March 1, 2027. That’s the same day many large public companies’ 10-Ks are due. If your auditor’s name is on it, the next four months matter.

Most coverage has treated the November 6 notice as an administrative cleanup. For the issuers those firms audit, it’s a deadline. By the end of this post, you’ll know what the notice means, how the 60-day clock works, how to check your auditor and any other firms that work on your audit, and the Form 8-K Item 4.01 steps if you need a new auditor.

What did the PCAOB announce on November 6, 2026?

On November 6, 2026, the Public Company Accounting Oversight Board (PCAOB) announced that it had sent a Notice of Delinquency and Impending Withdrawal to 97 registered audit firms in the U.S. and overseas. The notices, dated November 5, 2026, were issued under PCAOB Rule 2107(h), Constructive Withdrawal Requests. It’s the first use of that rule.

According to CPA Practice Advisor’s report, the PCAOB lists each firm with a notice date of November 5, 2026, and an impending withdrawal date of March 1, 2027. The full list is on the PCAOB’s constructive withdrawal notices page.

PCAOB Chairman Demetrios (Jim) Logothetis said the action gives investors a more accurate picture of the audit firms that remain active in the public company audit space. CFO Dive described the notice as administrative housecleaning with no sign of enforcement activity.

Who’s on the list

The list includes firms based in the U.S., China, Mexico, Germany, Turkey, India and elsewhere. Some names include large global network brands, such as BDO China Zhonglian Mindu Shu Lun Pan CPAs Co., Ltd., BDO Kazakhstanaudit LLP and RSM & Co.

A network name isn’t the network. Each member firm registers with the PCAOB separately. A listed firm with a BDO, RSM or UHY name is a distinct legal entity, and its notice says nothing about the registration of the network’s U.S. firm or other member firms. Match the exact legal name and PCAOB firm ID, not the brand.

What is a constructive withdrawal under PCAOB Rule 2107(h)?

A constructive withdrawal lets the PCAOB treat a firm’s repeated failure to file annual reports and pay annual fees as a request to withdraw its registration. The board sends a notice to the firm’s primary contact. If the firm doesn’t email the PCAOB within 60 days saying it wants to stay registered, the board may deem its registration withdrawn.

Think of it like a dormant bank account. If you stop using the account and ignore every letter, the bank eventually closes it. But if you reply within the deadline, it stays open.

The rule’s mechanics

The text of PCAOB Rule 2107 sets out the process:

1. Delinquency. The firm has failed, consecutively, to file its annual reports and pay its annual fees. The SEC’s approval order describes a two-year benchmark as the proxy for firms that likely no longer operate or wish to remain registered.
2. Notice. The board sends a Notice of Delinquency and Impending Withdrawal to the firm’s primary contact by mail or courier, and posts the notice on its website.
3. The 60-day window. The firm’s primary contact can stop the process by emailing the PCAOB’s registration staff within 60 days of the notice date.
4. Withdrawal. If no email arrives, the board may deem the firm’s registration withdrawn.

The PCAOB lengthened the response period from 30 days to 60 days during rulemaking, as an additional safeguard for firms that are delinquent but want to remain registered, according to Thomson Reuters. A withdrawn firm isn’t barred from registering again later.

Key dates

• November 5, 2026: Notices dated and sent.
• November 6, 2026: The PCAOB announces the notices and posts the list.
• About January 4, 2027: The 60-day response window ends, 60 days after November 5.
• March 1, 2027: The impending withdrawal date listed by the PCAOB.

Confirm the exact response deadline with the PCAOB or your auditor, since it runs from the date each notice was sent.

Why does this matter to public companies?

It matters because only PCAOB-registered firms can prepare or issue audit reports for public companies. If your auditor’s registration is withdrawn, it can’t issue your next audit report. March 1, 2027, falls in the middle of 10-K season for calendar-year filers, so an affected company could be left without an eligible auditor just before its deadline.

How the timing lines up with 10-K deadlines

For a company with a December 31, 2026 fiscal year end, the 2027 Form 10-K deadlines fall on or around these dates:

• Large accelerated filers have 60 days, so their 10-K is due around March 1, 2027, the same day as the listed withdrawal date.
• Accelerated filers have 75 days, so their 10-K is due around March 16, 2027.
• Non-accelerated filers have 90 days, so their 10-K is due around March 31, 2027.

Smaller audit firms tend to audit smaller companies, many of which are non-accelerated filers with a March 31 deadline. An audit report from a firm whose registration was withdrawn on March 1 would cause a serious problem for that 10-K.

Most listed firms likely have no issuer clients

The rule targets firms that haven’t filed annual reports or paid fees for an extended period, which usually signals a firm that has stopped auditing public companies or no longer exists. The SEC said as much when it approved the rule. Most issuers won’t be affected. But “most” isn’t “all,” which is why each company should check.

How many public companies are affected?

We cross-matched the 97 firm names against audit reports filed on EDGAR and the PCAOB’s Form AP auditor data from [period]. Here’s what we found:

• [X] of the 97 firms signed at least one audit report for an SEC registrant since [date].
• [X] registrants had their most recent audit report signed by a listed firm.
• [X] listed firms appeared on Form AP as other accounting firms participating in an issuer audit.
• [X] listed firms showed no issuer audit activity at all.

[Editor: describe the method in one sentence, for example: “We searched EDGAR full-text search and PCAOB AuditorSearch for each firm’s exact legal name in Form 10-K, 10-Q, 20-F and S-1 filings and Form AP data from January 2025 to November 2026.”]

What should issuers do now? A seven-step checklist

Check your auditor, any other firms that participate in your audit, and any predecessor auditor whose report you still use. If a firm is on the list, get written confirmation that it emailed the PCAOB within the 60-day window. If it didn’t, or won’t, start selecting a new auditor immediately.

1. Check your current auditor. Compare the exact legal name and PCAOB firm ID of your auditor against the PCAOB’s list.
2. Check other participating firms. Review your most recent Form AP for other accounting firms that took part in your audit, including component auditors outside the U.S. A listed firm in that role still affects your audit.
3. Check predecessor auditors. If your filings include financial statements audited by a prior firm, and you’ll need that firm’s consent or a reissued report (for example, in a registration statement), check that firm too.
4. Confirm registration status independently. Use the PCAOB’s registered firm records and AuditorSearch to confirm the firm’s current status. Don’t rely on the firm’s own statement alone.
5. Get written confirmation. If a listed firm says it will stay registered, ask for written confirmation that it emailed the PCAOB before the 60-day deadline. Then confirm that it’s no longer on the PCAOB’s list.
6. Brief your audit committee. Auditor selection and oversight belong to the audit committee. Brief it now, even if the answer is “not affected.”
7. Plan a contingency. If there’s any doubt, start identifying replacement firms now. A new auditor needs time for acceptance procedures, independence checks and planning before it can audit your year-end.

Tip: Put the auditor-status check on your disclosure committee’s year-end agenda every year. This is the first constructive withdrawal notice, and it won’t be the last.

What are the Form 8-K Item 4.01 steps if you change auditors?

If your auditor resigns, declines to stand for reappointment, or is dismissed, you must file a Form 8-K under Item 4.01 within four business days. The 8-K must include the disclosures required by Item 304 of Regulation S-K, and you must ask the former auditor for a letter saying whether it agrees with them. Engaging a new auditor is also reported under Item 4.01.

The Item 4.01 sequence

1. The triggering event. The former auditor resigns or declines to stand for reappointment, or the audit committee dismisses it.
2. File the 8-K within four business days. Report the change under Item 4.01.
3. Make the Item 304 disclosures. For the two most recent fiscal years and any later interim period, state whether:
   • the auditor’s report contained an adverse opinion or disclaimer of opinion, or was qualified or modified;
   • the change was approved by the audit committee or board;
   • there were any disagreements with the auditor; and
   • any “reportable events” occurred, such as material weaknesses the auditor advised you of.
4. Request the former auditor’s letter. Give the former auditor a copy of the disclosure and ask it to furnish a letter stating whether it agrees.
5. File the letter as Exhibit 16. The former auditor must provide the letter within 10 business days after the 8-K is filed. You must file it, by amendment if needed, within two business days of receiving it.
6. Report the new engagement. When you engage a new auditor, report it under Item 4.01. Disclose any consultations with the new auditor during the two most recent fiscal years on matters Item 304 specifies.

What makes this situation unusual

A constructively withdrawn firm may be hard to reach. That’s often why it became delinquent in the first place. If the former auditor doesn’t respond to your request for an Exhibit 16 letter, document your request and its timing, and get advice from securities counsel on how to disclose the missing letter.

You should also consider the effect on prior-year financial statements that the former firm audited. If you’ll need its report or consent in a future filing, such as a registration statement, a withdrawn firm may not be able to provide it. That may require a re-audit. Discuss this early with your new auditor and counsel.

Frequently asked questions

What did the PCAOB announce about 97 audit firms?

On November 6, 2026, the PCAOB announced it had sent a Notice of Delinquency and Impending Withdrawal to 97 registered audit firms under Rule 2107(h), Constructive Withdrawal Requests. The notices are dated November 5, 2026, and list an impending withdrawal date of March 1, 2027. It’s the first time the PCAOB has used the rule, which it adopted in 2024.

What happens if an audit firm doesn’t respond to the PCAOB notice?

If the firm’s primary contact doesn’t email the PCAOB’s registration staff within 60 days of the notice saying the firm wants to remain registered, the PCAOB may deem its registration withdrawn. A withdrawn firm can’t prepare or issue audit reports for public companies. It isn’t permanently barred, however, and can apply to register again.

Can a public company use an auditor that isn’t PCAOB-registered?

No. The Sarbanes-Oxley Act requires a public accounting firm to be registered with the PCAOB to prepare or issue audit reports for issuers. If your auditor’s registration is withdrawn, it can’t issue your next audit report. You would need to engage a registered firm and report the change on Form 8-K under Item 4.01.

How do I check whether my auditor is on the PCAOB list?

Compare your auditor’s exact legal name and PCAOB firm ID with the PCAOB’s constructive withdrawal notices page. Then confirm its current status in the PCAOB’s registration records or AuditorSearch. Also check other accounting firms named on your Form AP and any predecessor auditor whose report you still use in your filings.

What does Form 8-K Item 4.01 require when changing auditors?

Item 4.01 requires an 8-K within four business days of an auditor’s resignation, dismissal or decision not to stand for reappointment, and when a new auditor is engaged. It must include Item 304 of Regulation S-K disclosures, such as disagreements and reportable events. The former auditor’s letter saying whether it agrees is filed as Exhibit 16.

How can Finrep help with the PCAOB withdrawal list?

Finrep searches more than 10 million SEC filings on EDGAR and returns answers cited to the source filing. Teams use it to see which registrants named a particular audit firm, check exposure across subsidiaries and counterparties, and review peers’ Item 4.01 8-Ks and Exhibit 16 letters when drafting their own auditor-change disclosures.

Key takeaways

• 97 firms, one deadline. The PCAOB lists an impending withdrawal date of March 1, 2027, the day large accelerated filers’ 10-Ks are due.
• Firms have 60 days to respond. An email to the PCAOB’s registration staff within 60 days of the notice keeps a firm registered.
• Check every firm in your audit. Look at your auditor, other participating firms on Form AP, and any predecessor auditor.
• Match exact names, not brands. A network name on the list doesn’t mean the network’s U.S. firm is affected.
• Know your Item 4.01 steps. Four business days to file, Item 304 disclosures, and an Exhibit 16 letter from the former auditor.
