What to Know
- $430 million in annual attestation revenue is at risk for the Big Four if the SEC’s Section 404(b) exemption is finalized
- 1,700 public companies would be freed from independent internal controls audits under a new $2 billion public float threshold
- EY, Deloitte, PwC, and KPMG have all formally opposed the proposal alongside investor advocacy groups
- The affected companies collectively paid $3.8 billion in total audit fees in the prior year
The SEC audit exemption now on the table in Washington is the most aggressive rollback of post-Enron investor protections in more than two decades, and the Big Four accounting firms are not taking it quietly. SEC Chair Paul Atkins wants to triple the public float threshold that determines which companies must obtain independent internal controls audits, a change that would free roughly 1,700 public companies from a core requirement of the Sarbanes-Oxley Act and wipe out an estimated $430 million in annual audit revenue from US accounting firms.
What Is the SEC Audit Exemption Proposal?
The SEC audit exemption proposal would raise the Section 404(b) public float threshold from $700 million to $2 billion, exempting roughly 1,700 companies from independent internal controls audits. Under the current rule, outside auditors must verify that a company’s financial reporting systems actually work, not only that the financial statements appear accurate on their face.
Paul Atkins framed the measure as part of a wider effort to reduce barriers for mid-sized companies weighing whether to list on US exchanges. The argument is that expensive attestation requirements act as a deterrent that pushes otherwise healthy businesses toward staying private or listing abroad. Paul Atkins SEC Section 404b public float threshold $2 billion outlines the full scope of what the SEC is proposing, including the specific changes to the attestation threshold.
The rule being targeted, Section 404(b), sits inside the Sarbanes-Oxley Act that Congress passed in 2002 following the collapse of Enron and WorldCom. It requires outside auditors to go beyond the numbers on the page and independently verify that the internal systems producing those numbers are actually sound. That distinction is the one the proposal would remove for a large slice of the public market.
How Much Revenue Do Big Four Firms Stand to Lose?
The $430 million figure is the portion of annual audit revenue tied directly to Section 404(b) attestation work among the companies that would be exempted. Those companies collectively paid $3.8 billion in total audit fees in the prior year, so the $430 million chunk represents the specific work of independently verifying internal controls, separate from the broader audit relationship.
All four of the major audit firms have come out against the change. Big Four accounting firms $430 million SEC 404b deregulation 2026 covers the industry opposition in detail, including the coordinated pushback from EY, Deloitte, PwC, and KPMG. The Center for Audit Quality and several investor protection groups joined them in opposing the measure.
The opposition from accounting firms is not purely about losing revenue, though that is clearly part of it. Their substantive argument is that independent attestation catches problems that standard audits miss, particularly in companies where management has the incentive to present internal processes in the most favorable light. Removing that check does not make those problems disappear. It just makes them harder to find before they become crises.
Why Did Congress Create Section 404(b)?
Enron’s $63 billion bankruptcy in 2001 and WorldCom’s $11 billion accounting fraud were not caused by small companies cutting corners. Both were established enterprises with full audit relationships. Their internal controls either failed or were actively circumvented, and standard audits did not catch the problems before they became catastrophic for shareholders. Congress wrote Section 404(b) specifically because the existing framework had demonstrably proven inadequate.
The original version of Sarbanes-Oxley applied 404(b) to all public companies without exception. Smaller firms pushed back hard on the compliance cost, and regulators eventually carved out a threshold. The $700 million public float exemption that exists today was itself a compromise, not the design intent of the law’s original architects.
SEC Sarbanes-Oxley 404b audit exemption 1700 companies 2026 documents how the current proposal extends that exemption further up the market cap ladder. Moving the threshold from $700 million to $2 billion applies the same logic to a larger set of companies, but it also applies it to companies large enough that internal control failures could cause meaningful harm to public shareholders.
That is the fundamental problem with the deregulatory argument here. The cost-reduction case is real and internally consistent. But the Sarbanes-Oxley reforms were not designed with small companies in mind. They were designed for companies at exactly the size where the proposal would now remove the requirement.
What Does the SEC Audit Exemption Mean for Investors?
For retail shareholders holding positions in mid-cap companies, this proposal removes one layer of external verification that currently sits between them and management’s internal reporting. Independent attestation under Section 404(b) is not a fraud guarantee, but it is an outside set of eyes reviewing whether the company’s own tracking systems can be trusted.
Supporters will point out that companies still need to conduct their own internal controls assessment under Section 404(a), even without the independent audit requirement. Technically, that is correct. But there is a meaningful difference between a company reviewing its own controls and an outside auditor doing the same work. The history of corporate accounting failures is largely a record of companies whose internal self-assessments were fine right up until they were not.
If you are holding shares in a company between $700 million and $2 billion in public float, this is the rule that currently requires someone independent to confirm the financial machinery is working properly. The proposal removes that confirmation. The financial statements still get audited. The systems producing them do not.
Is This Part of a Broader Deregulatory Push?
Yes. The SEC under Paul Atkins has moved consistently to reduce compliance costs since the administration took office, and this Section 404(b) proposal is part of that pattern. The broader argument is that US public markets have become too expensive to access, IPO volumes have declined, and the compliance cost structure contributes to companies choosing to stay private longer or list on foreign exchanges.
The deregulatory logic is coherent on its own terms. The $700 million threshold was itself the product of a years-long effort to reduce Sarbanes-Oxley compliance burdens on smaller issuers. Raising it to $2 billion is the same argument applied more aggressively. The administration is betting that reducing friction for mid-market companies will bring more listings to US exchanges.
A bet like that always comes with a tradeoff. Every company that goes public between the old threshold and the new one will carry shareholders who lack the independent controls verification that comparable companies currently provide. Whether that tradeoff is worth it depends on how much weight you put on the fraud-prevention function of Section 404(b) versus the cost reduction for issuers. Paul Atkins has made his choice clear. The Big Four have made theirs. Public investors are the ones who live with the outcome.
Frequently Asked Questions
What is the SEC audit exemption proposal?
The SEC audit exemption proposal would raise the Section 404(b) public float threshold from $700 million to $2 billion. Companies below the new threshold would no longer need an independent auditor to verify their internal financial controls. The change would exempt approximately 1,700 public companies from this requirement.
How much money could the Big Four accounting firms lose?
The Big Four firms, EY, Deloitte, PwC, and KPMG, could lose an estimated $430 million in annual audit revenue tied to Section 404(b) attestation work if the SEC proposal is finalized. The affected companies collectively paid $3.8 billion in total audit fees last year, with the $430 million covering only the internal controls verification piece.
Why was Section 404(b) of Sarbanes-Oxley created?
Congress added Section 404(b) to the Sarbanes-Oxley Act in 2002 after the Enron and WorldCom accounting scandals demonstrated that standard financial audits alone were not sufficient to catch major internal control failures. The section requires outside auditors to independently verify that a company’s financial reporting systems function correctly, going beyond reviewing the financial statements themselves.
How many companies would the new 404(b) exemption affect?
Approximately 1,700 public companies would fall under the new exemption if the Section 404(b) threshold rises from $700 million to $2 billion in public float. These are mid-cap companies with significant retail and institutional investor bases. They would still need a standard financial audit but would no longer be required to obtain independent attestation of their internal controls.
