How Accounting Problems Delay an IPO: Material Weaknesses, Restatements, and SEC Comments

An IPO is a deadline business. Underwriters plan around market windows, financial statements go stale on a fixed calendar, and a slipped audit can mean refiling with new numbers. Accounting problems are one of the most common reasons a timeline slips, and some of them stay in the prospectus for every investor to read. Here is where they come from and how to avoid them.

Material weaknesses are common, and they are disclosed

A material weakness is a deficiency in internal control serious enough that a material error in the financial statements might not be prevented or caught in time. If your auditor identifies one during the audit for the IPO, it is normally disclosed as a risk factor in the registration statement.

They are more common than many founders expect. In KPMG's study of U.S. IPOs, 44% of the 122 traditional IPOs that closed in 2023 disclosed a material weakness in their initial registration statement, after 58% in 2022 and 40% in 2021. The causes KPMG most often found were a lack of people with enough knowledge of U.S. GAAP and complex transactions, controls that were missing or poorly designed, and a lack of formal policies and procedures. The process areas most often involved were financial reporting and the close, non-routine and complex transactions, systems, equity, revenue, and tax.

A disclosed weakness does not stop an IPO, but it is an early warning to investors. The company also has to explain its remediation plan and report on progress after listing.

Restatements and late audit adjustments

When the PCAOB audit finds errors in previously issued financial statements, those statements are restated. Before an IPO that usually means revised numbers, a longer audit, and often a material weakness disclosure as well. The usual sources are predictable:

• Revenue recognized too early, or bundled contracts not split into performance obligations under ASC 606
• Convertible notes, SAFEs, and warrants classified incorrectly between debt, liabilities, and equity
• Stock compensation expense calculated on stale or unsupported grant-date values
• Leases kept off the balance sheet after ASC 842 took effect
• Capitalized costs that should have been expensed
• Missing accruals at period-end, so expenses land in the wrong year

Each of these is easier and cheaper to fix during a pre-IPO review than during the audit, and far cheaper than after the S-1 is public.

SEC comment letters

The SEC staff reviews IPO registration statements and sends comment letters, and the company answers each comment before the registration statement can be declared effective. Accounting firms that track these letters consistently find that a few areas generate most of the comments:

• Management's discussion and analysis (MD&A): explaining why results changed, not just how much
• Revenue recognition: how performance obligations, timing, and principal-versus-agent conclusions were reached
• Non-GAAP measures and key metrics: how adjusted figures are defined and reconciled, and whether they are given more prominence than GAAP numbers
• Segment reporting: whether the segments match how management actually runs the business
• Stock compensation and "cheap stock": how the fair value of pre-IPO grants was determined
• Age of financial statements: whether the numbers will still be current at effectiveness

Each round of comments takes time to answer and review. Clear accounting policies and well-written memos written before filing reduce how many rounds you go through.

The staleness clock

Financial statements in a registration statement have a shelf life. If the registration statement becomes effective more than 134 days after the fiscal year-end, it generally has to include reviewed interim financial statements, and annual statements cannot be more than a year and 45 days old at effectiveness. If an audit runs late or a comment round takes longer than expected, the company may need to close and present another quarter before it can go effective. A fast, reliable monthly close is therefore not just a post-IPO requirement. It protects the IPO calendar.

Costs are usually higher than expected

In a PwC survey of executives at companies that had completed an IPO, 43% said accounting and financial reporting costs were higher than they expected. Most of the surprise comes from rework: re-auditing years, rebuilding equity records, and hiring advisers late to fix problems that could have been found in a readiness assessment.

How to avoid the most common problems

• Get a readiness assessment 12 to 24 months out. Compare your books, policies, and controls with what a PCAOB audit and the SEC will require.
• Write the key accounting memos now: revenue recognition, equity instruments, leases, and capitalized costs.
• Value every equity grant when it is made and keep the valuation reports.
• Close every month on a calendar, with reconciliations reviewed by someone other than the preparer.
• Fill the expertise gap early. Bring in a technical accounting adviser or an SEC reporting specialist before the audit, not in response to it.

Frequently asked questions

Does a material weakness mean we cannot go public?

No. Many companies go public with a disclosed material weakness. It must be described in the registration statement along with the plan to fix it, and investors and analysts will watch whether it is remediated.

Can we fix a material weakness before filing?

Often, yes, if it is found early enough. Remediation means designing and operating new controls long enough to show they work, which usually takes at least one or two quarterly closes.

How many rounds of SEC comments should we expect?

It varies. Companies with clear disclosures and well-supported accounting judgments tend to have fewer and shorter rounds. Your counsel and auditor can give you a realistic range for your industry.

What is the single biggest accounting risk in an IPO?

It depends on the business, but revenue recognition and equity accounting are the two areas most often involved in late adjustments and SEC comments.
