Key Steps and How Long It Takes

PublicFinancial.com IPO Knowledge Hub Series


One of the most common founder questions: “If we start now, when could we realistically go public?”


Here’s what the typical IPO timeline looks like — and what can speed it up or slow it down.


Key Founder Questions: IPO Timeline & Process

1️⃣ How long does the IPO process take?

6 to 18 months is typical.

Shorter timelines (6–9 months) apply to companies with:

  • Clean, audited financials.
  • Strong internal controls.
  • Prior preparation for public company requirements.

Longer timelines (12–18+ months) apply when:

  • Financial systems or reporting need upgrades.
  • Governance changes are required.
  • Legal or structural issues must be addressed.

2️⃣ What are the major steps and milestones?

Step 

  • Preliminary readiness assessment                                 
  • Hire key advisors                                                                 
  • Financial audits & SOX preparation                               
  • Draft S-1 registration statement                                     
  • File S-1, SEC review & comment rounds                         
  • Investor marketing (roadshow or Investor Day)       
  • Price offering & list shares                                               


Note: Many activities overlap, and delays in one area can affect the entire timeline.

3️⃣ How does a direct listing timeline differ?


Very similar, except:

  • No need to prepare new capital raise disclosures.
  • No underwriter-led roadshow.
  • Slightly faster in some cases (but dependent on SEC review and exchange approval).


4️⃣ When should we start engaging advisors?


  • As early as possible.
  • Legal counsel and auditors should be engaged 6-12 months before filing.
  • Underwriters or financial advisors typically engage 6–9 months before listing.


5️⃣ Can we speed up the process?

Yes, by:

  • Starting readiness work early.
  • Resolving audit or governance gaps upfront.
  • Choosing experienced advisors.


But moving too quickly can also introduce risks — careful preparation is more important than sheer speed.

6️⃣ What if market conditions change during the process?

  • Before filing: You can pause at any time.
  • After filing: You can delay or withdraw, though costs incurred will not be recoverable.

7️⃣ Is there an ideal window or season for an IPO?

Many companies target:

  • Spring (March to early June)
  • Fall (September to mid-November)


Avoid summer and holiday periods when investor attention is lower.
