S-1 Clock: The 24-Month Pre-IPO Accounting Checklist

The 24-Month Countdown

Going public is not an event — it is a multi-year transformation. The S-1 registration statement requires audited financial statements, and the accounting foundation must be SEC-ready well before the filing date.

Month 24-18: Foundation Phase

• Select Big 4 or national firm as auditor with SEC practice
• Evaluate EGC (Emerging Growth Company) eligibility
• Assess revenue recognition under ASC 606
• Begin SOX 404 readiness assessment
• Document all related-party transactions

Month 18-12: Build Phase

• Implement PCAOB-compliant internal controls
• Prepare carve-out financials if needed
• Establish disclosure committee
• Begin equity compensation accounting (ASC 718)
• Address cheap stock issues and 409A valuations

Month 12-6: Refinement Phase

• Complete first dry-run S-1 draft
• Remediate material weaknesses
• Prepare MD&A narratives
• Finalize segment reporting (ASC 280)
• Brief underwriters and legal counsel

Month 6-0: Execution Phase

• File confidential S-1 (if EGC)
• Complete SEC comment letter responses
• Finalize offering price range
• Prepare Day 1 public company infrastructure
• Establish investor relations program

Key Takeaway: The companies that go public smoothly are the ones that start preparing 24 months out, not 12.
