The right time is when all five internal readiness gates are cleared simultaneously and the external IPO market window is open for your sector.
Most owners fail in one of two ways. They move too early, before governance and audit infrastructure are in place, and end up withdrawing an S-1 or pricing a busted IPO. Or they clear the readiness gates and then wait indefinitely, missing a market window that may not reopen for 12 to 24 months. Readiness is necessary. It isn't sufficient. The right moment is both clocks green at the same time.
What does "the right time" actually mean for an IPO?
It means two clocks are aligned: you've cleared all five internal readiness gates, and the external IPO market window is open for your sector. One without the other is a false start.
The five gates are concrete: PCAOB-quality audited financials (two years minimum), a $50M+ EBITDA floor, a public-company CFO, an independent board director, and securities-experienced outside counsel. Every institutional investor walks through each of them on the roadshow. A gap in any one either kills the deal or reprices it downward.
The market window is a separate variable. A company with all five gates cleared can still be wrong to file. If institutional investors aren't buying services-sector IPOs, or if macro volatility has shut down deal pricing, filing into that environment wastes every month of preparation that came before it.
Which five gates must you clear before you file?
All five, in order. Skip one and the SEC finds it in comment letter #1. Or you find it on roadshow when an institutional investor asks your CFO to walk through a 40-day close and he can't.
Gate 1: PCAOB-quality audit (two fiscal years minimum). Not the same as a standard CPA audit. PCAOB-standard is required for SEC registration. Emerging Growth Companies under the JOBS Act only need two years instead of three, but that clock starts when you hire a PCAOB-registered auditor, not when you decide to go public. Most roofing companies run standard GAAP audits or reviews. Converting takes 12-18 months of clean operating history.
Gate 2: $50M+ EBITDA. The $50M floor isn't an SEC rule. It's math. Two-thirds of public-company CFOs estimated spending $1M to $1.9M annually on the incremental costs of staying public. On $50M EBITDA, that's 2-4% of earnings. On $10M EBITDA, it's 10-20%. The PwC Roadmap to an IPO lays out the full cost structure. Below the floor, being public erodes the margin that justified going public.
Gate 3: Public-company CFO. A controller who closes month-end is not this person. The public-company CFO runs quarterly close in 40 days, certifies under SOX 302 and 906, and manages analyst expectations on earnings calls. Source, onboard, and prep: 6-12 months minimum.
Gate 4: Independent board director. Exchange listing standards require independent directors; the audit committee must be fully independent. Hard to source fast if you don't already have one.
Gate 5: Securities-experienced outside counsel. An attorney who has run an S-1 before — not your M&A lawyer.
Beacon Roofing Supply (NASDAQ: BECN) filed its S-1 on May 28, 2004 and began trading September 22, 2004, after building to 66 branches across 12 states as a private-equity-backed acquisition platform. Beacon didn't approach an investment bank before it had the infrastructure. That's the sequencing that works.
How do you know if the external market window is open?
Three signals: VIX below approximately 20, rising IPO volume in your sector, and recent sector IPOs trading at or above their offer price. All three green: the window is open. Any one red: underwriters delay.
Deloitte reported that 2025 delivered roughly $44 billion in IPO proceeds, the strongest year since 2021, with VIX ending the year around 15. That's the level that supports pricing accuracy. Services and industrials showed steady institutional receptivity throughout the year, and the 2026 pipeline entered the year strong.
As RSM noted, windows can open and close quickly. Companies that are prepared move when conditions align. Those that wait too long miss their chance entirely.
How long does it take to pass all five gates?
Eighteen to twenty-four months from the day you commit, assuming no major gaps. If your audit isn't already PCAOB-quality, add 12 months before you start counting.
The timeline is sequential:
- Months 0-3: Internal gap assessment. Current audit standard, CFO capabilities, board composition.
- Months 3-12: Hire PCAOB-registered auditor if not already done. Begin converting historical financials. Start board recruitment.
- Months 6-18: Hire or upgrade the public-company CFO. Install financial systems that support a 40-day quarterly close.
- Months 12-24: Two full PCAOB-quality fiscal years complete. Board structure in place. Securities counsel retained.
- After readiness: Watch the market window. File when conditions align.
PwC recommends "an orderly plan executed over a one- to two-year period" and notes the most successful IPOs come from companies already operating like a public company in the year before listing. Start from scratch with no PCAOB auditor, no CFO, and no independent director, and three years is realistic.
