Form S-1: Required Financial Statements

Going public takes some fairly decent preparation on the part of the offerer. Nowhere is this more evident than in the financial statements. Prior to your public offering, whether you go public via IPO, DPO or APO via reverse merger, you’ll be required to make certain financial disclosures of fact, in accordance with GAAP (Generally Accepted Accounting Principles) and audited by a PCAOB auditing firm.

What follows is a brief description of each of the key financial statements your company will be required to prepare for submittal to the Securities and Exchange Commission.

The Four Core Financial Statements Required by the SEC

1. Balance Sheet. Audited, consolidated (if there are subsidiaries) balance sheets for the end of the two most recent years. If your company has been in existence for a year or less, then you must provide an audited balance sheet as of a date within 134 days of the filing of the public registration.

2. Income Statement. Audited income statement for each of the three fiscal years preceding the date of the most recent audited balance sheet being filed. This could be shortened, depending on how long your company has existed.

3. Cash Flow Statement. Audited cash flow statement for each of the three preceding fiscal years.

4. Interim Reviewed Financial Statements. If the filing is over 134 days after the end of your fiscal year, then you’ll be required to submit Interim Reviewed Financials. Rule 8-01 of Reg S-X provides information and requirements on the specific periods your financials must cover as a smaller reporting public company.

Smaller Reporting Company Definitions

Smaller reporting companies are defined as:

• Company with Trading Stock. A company with a public float of less than $75 million as of the previous business day from the company’s most recently completed fiscal quarter. This is computed by multiplying the aggregate number of shares (both voting and non-voting) of the company’s common stock, held by non-affiliates, multiplied by the price at which the common equity was last sold.
• Company with Non-Trading Stock. If the company’s stock isn’t trading, then the market cap is pegged from the initial registration statement. Using common equity, the company has a public float of less than $75 million within 30 days of the date of registration statement filing.
• Annual Revenues. If, when calculating the public float mentioned above, the public float is zero and the annual revenues were less than $50 million.

Why PCAOB Audits Matter

The Public Company Accounting Oversight Board (PCAOB) sets auditing standards that differ meaningfully from the standards applied to private-company audits. The SEC requires that every financial statement included in an S-1 registration be audited by a PCAOB-registered firm—a requirement that often catches founders off-guard. Many early-stage companies have used respected regional accounting firms for their annual audits, only to discover those firms lack PCAOB registration. Identifying and engaging a qualified auditor early—often 12 to 18 months before an anticipated filing—is one of the most consequential steps in the going-public timeline.

Once a PCAOB-registered auditor is engaged, the firm will typically re-examine prior-year workpapers, which can surface adjustments that alter reported results. These “restatement risk” discoveries are far better handled before the S-1 is filed than after—public corrections post-filing create significant investor-relations and regulatory complications. Understanding how to present financial history accurately and compellingly is also important; well-organized recasting of financial statements can help buyers and investors understand true economic performance before due diligence begins.

Preparing for the Audit Timeline

The audit process for a public offering is rarely linear. Auditors require access to underlying records—general ledgers, bank reconciliations, contracts, payroll records, and subsidiary financials. For companies with complex revenue recognition (subscription models, long-term contracts, multi-element arrangements), auditors spend disproportionate time stress-testing revenue schedules. Similarly, companies carrying significant intangible assets or goodwill must be prepared to support impairment analyses.

Engaging outside financial advisors early—those familiar with the going public process—streamlines audit preparation considerably. Advisors can help management bridge the gap between “internal management accounts” and “SEC-ready GAAP financials,” which often requires reclassifying expenses, adjusting revenue recognition policies, and formalizing accounting memoranda. Maintaining clear internal records also helps you avoid surprises when preparing required SEC filings after you become a public reporting company.

Post-Filing Obligations

The financial disclosure obligations introduced in the S-1 do not end at the IPO. Once public, companies must maintain ongoing reporting requirements—quarterly (10-Q) and annual (10-K) filings—each with its own audit or review requirements. Building a finance and accounting infrastructure capable of supporting these obligations is a strategic priority that should be addressed well before the offering. Companies that underinvest in their finance function pre-IPO frequently struggle to meet reporting deadlines, creating stock-price volatility and heightened regulatory scrutiny. Review the full scope of required forms and schedules for public companies and officers to understand what comes next.

What’s mentioned above represents a broad description about the financial preparation that needs to occur as part of the going public process. Teams that start early, engage qualified professionals, and treat the audit as a business-improvement exercise—not just a compliance hurdle—tend to navigate the process most smoothly. If you are evaluating whether a public offering aligns with your growth objectives, preparing a transaction framework with experienced advisors is a practical first step.

Frequently Asked Questions

How far back must financial statements go for an S-1 filing?

The SEC generally requires audited balance sheets for the two most recent fiscal year-ends and audited income and cash flow statements for each of the three preceding fiscal years. Shorter histories are permissible if the company has been in existence for fewer years.

What is the difference between audited and reviewed financial statements?

An audit provides the highest level of assurance—auditors perform substantive testing and express a formal opinion. A review provides limited assurance through analytical procedures and inquiry but does not involve detailed testing. For an S-1, the annual statements must be audited; interim statements filed more than 134 days after fiscal year-end require a review.

Do smaller companies face different SEC financial statement rules?

Yes. Smaller reporting companies (SRCs)—generally those with a public float below $75 million or annual revenues below $50 million when float is zero—qualify for scaled disclosure requirements under Regulation S-X, including potentially fewer years of required audited statements.

Why does PCAOB registration matter for my auditor?

The SEC will not accept financial statements audited by a firm that is not registered with the PCAOB. Many well-regarded private-company auditors are not PCAOB-registered, so verifying your auditor’s status early—before beginning audit fieldwork—is essential to avoid costly delays in the registration process.
