IPO Readiness: Common Questions Answered
A reference guide for CFOs and financial leaders preparing to take a company public.
Every IPO is a different company, a different market, and a different team… but the questions the process raises tend to be remarkably consistent. What does the SEC actually scrutinize? When is early enough to start? What does ready really look like?
This page works through the most important of those questions with direct answers grounded in what the process requires. It is designed to be useful whether you are building your preparation plan or pressure-testing one already underway.

Getting started
How long does it take to prepare for an IPO?
Most advisors recommend beginning serious preparation 18 to 24 months before your target listing date. The S-1 filing itself is typically submitted confidentially 6 to 9 months before listing, but the audit history, governance infrastructure, and data discipline required to support that filing take considerably longer to build. Companies that compress this timeline almost always encounter avoidable delays, regardless of how experienced the team is.
IF THIS IS YOUR FIRST IPO
If this is your first IPO, the 18-month figure tends to feel conservative until you are 12 months out and realizing how much groundwork remains. The workstreams that take the longest to build correctly, audit history, SOX program development, and cap table reconciliation, are also the ones most commonly started too late. The timeline is not a suggestion.
What is the first thing a CFO should do when an IPO becomes a realistic possibility?
Appoint an IPO steering group with clear workstream ownership, then select your core outside partners before substantive preparation begins. The partners who matter most early are external counsel, PCAOB-level auditors, a transfer agent, and your equity management platform. Decisions made at this stage, particularly around audit firm and transfer agent, have downstream implications that are expensive to undo.
What is a transfer agent, and why does it matter for an IPO?
A transfer agent is the organization responsible for maintaining the official record of who owns your shares once you are a public company. They process share transfers, manage dividend payments, coordinate broker connectivity, and handle shareholder support. For an IPO, the critical handoff is from private cap table records to public shareholder records. If those two systems do not connect cleanly, the migration requires manual reconstruction, which introduces errors and consumes time the team does not have. Odyssey Trust Company serves as Carta’s exclusive North American transfer agent partner for IPO-focused companies, built specifically to make this handoff seamless.
What is the difference between NYSE and Nasdaq for a company going public?
Both are major exchanges with different quantitative listing requirements. Nasdaq is generally associated with technology and growth companies; NYSE has historically attracted more traditional industrial and financial issuers, though the distinction has blurred considerably. The practical difference lies in their listing pathways: each offers multiple routes based on income, equity, market value, or float, with different thresholds and continued listing requirements. Both have been active in revising standards in recent years. The right approach is to evaluate which exchange fits your profile, then build buffer above the thresholds rather than targeting them precisely.
Regulatory requirements
What is the S-1, and what does the SEC actually scrutinize?
The S-1 is the registration statement filed with the Securities and Exchange Commission to register your shares for public sale. It contains audited financial statements, the Management’s Discussion and Analysis (MD&A), risk factors, a business description, governance disclosures, and the terms of the offering. SEC staff review focuses most heavily on the MD&A, which must explain what drove changes in results, what trends are expected ahead, and how the business plans to fund itself, with quantified support wherever possible. Vague language generates comment letters. Specific, well-evidenced explanations move through review faster.
What is MD&A and why does the SEC focus on it so heavily?
MD&A stands for Management’s Discussion and Analysis. It is the narrative section of a financial filing where management explains the numbers rather than just presenting them. The SEC expects companies to identify the specific factors behind material changes in revenue, costs, and cash flow; discuss known trends and uncertainties; and explain liquidity and capital resources in concrete terms. The standard applies equally whether a company is filing for the first time or the tenth: the numbers need a story, and the story needs evidence.
IF THIS IS YOUR FIRST IPO
The most common MD&A problem on a first S-1 is describing results rather than explaining them. Saying revenue increased is not enough. The SEC expects you to say why it increased, by how much each contributing factor drove the change, and what you expect ahead. A comment letter on MD&A disclosure is one of the most time-consuming to respond to because it requires going back to data and documentation that should have been prepared months earlier.
What is Inline XBRL and does every IPO require it?
Inline XBRL, also called iXBRL, is a structured data format that tags key financial information in SEC filings so the data can be read and compared programmatically across companies. Most public company filings require it, and the scope of required tagging has expanded in recent years, including new requirements for SPAC transactions. Your filing vendor handles the technical tagging work, but selecting that vendor early and understanding your tagging scope before the filing sprint matters more than many teams anticipate. What looks like a vendor detail early in the process becomes a deadline constraint later.
What is SOX 404, and when does it apply?
IF THIS IS YOUR FIRST IPO
SOX 404 compliance is the workstream most frequently underestimated on a first IPO. Management’s assessment requires documented process narratives, risk and control matrices, IT general controls testing, and an evidence trail that demonstrates controls are not just designed correctly but operating as designed. That body of work takes 12 to 18 months to build properly. Teams that start at 6 months almost always find themselves remediating gaps under time pressure rather than demonstrating a program that runs.
Sarbanes-Oxley Section 404 has two components. Section 404(a) requires management to formally assess and report on the effectiveness of internal controls over financial reporting. This applies to all public companies and must be addressed in the first annual report after listing. Section 404(b) adds an auditor attestation requirement, but it applies only to accelerated filers. Smaller reporting companies and non-accelerated filers are exempt from 404(b). Your filer classification at the time you become a reporting company determines which requirements apply and when, so understanding your projected classification early shapes how you scope and resource your SOX program.
What are PCAOB auditing standards?
PCAOB stands for the Public Company Accounting Oversight Board. It is the regulator that sets auditing standards for firms that audit public companies in the United States. Financial statements included in the S-1 must be audited by a PCAOB-registered firm under PCAOB standards, which represent a higher bar than the AICPA standards that govern most private company audits. If your current audit firm is not PCAOB-registered, transitioning to one that is should be among the first decisions made when an IPO becomes a realistic goal.
Cap table and equity records
Why is the cap table such a high-risk area in the IPO process?
The cap table is the authoritative record of who owns equity in your company and on what terms. Errors create cascading problems: they affect the financial statements, the S-1 disclosures, the equity compensation footnotes, and the share count underlying every per-share calculation. Because cap table records accumulate over years of grants, exercises, cancellations, secondaries, SAFEs, and convertibles, small discrepancies compound. The public company standard is zero tolerance for discrepancies between the equity platform, the general ledger, and board approval documentation. Finding errors during a planned review is manageable. Finding them during SEC comment resolution is not.
What does it mean to reconcile the cap table to the general ledger?
It means confirming that the total equity values in your financial statements match the individual grant and transaction records in your equity management platform, down to the last share. Every option grant, RSU award, exercise, cancellation, and transfer needs a corresponding entry, and board approval documentation must exist for every issuance. In practice, this reconciliation often surfaces small discrepancies accumulated over time. The earlier it is done, the less disruptive those findings are to address.
What is the Carta to Odyssey data migration?
When a Carta-managed company goes public, the equity records maintained in Carta move to Odyssey Trust Company, which becomes the official transfer agent for public shareholder records. The integration between the two platforms is designed to make this a structured, clean data transfer rather than a manual rebuild. That distinction matters because manual reconstruction of shareholder records at filing time introduces both errors and significant time costs at exactly the moment the team has the least capacity to absorb either.
Timeline and sequencing
What should a company have in place 18 months before its target listing date?
At 18 months, the priorities are foundational:
- IPO steering group appointed with workstream ownership assigned
- Auditors, counsel, underwriters, transfer agent, and financial printer selected
- Target exchange confirmed and quantitative listing path mapped with buffer
- Monthly and quarterly closes running with documented MD&A-style explanations
- SOX program scoped and underway
- Cap table confirmed as reconciled and equity platform established as system of record
What should a company have in place 12 months before its target listing date?
At 12 months, the work shifts to locking decisions and building documentation:
- Complex accounting positions resolved with auditor alignment: revenue, leases, equity comp, segments
- Year-end audit complete or near complete
- ERP and billing system issues addressed so audit evidence is producible without friction
- Board committees established and
What should a company have in place 6 months before its target listing date?
At 6 months, the focus shifts to filing mechanics and operational readiness:
- All S-1 sections finalized: financial statements, MD&A, risk factors, and exhibits
- SOX 404(a) management testing complete
- Exchange application submitted and ticker reserved
- Transfer agent onboarding and broker connectivity complete and tested
- Day 1 and T+1 operational procedures rehearsed
How much does the timeline change if the company has been public before?
The regulatory framework and core workstreams are the same regardless of prior experience. What changes is the degree of institutional familiarity your team brings to each one. Experienced teams typically move faster through partner selection, SOX program design, and MD&A drafting because they know what “good” looks like. But the timeline itself does not compress as much as most people expect, particularly if the company’s equity records, internal controls, or financial systems need meaningful work before they meet the public company standard. The preparation arc reflects what the process requires, not what feels reasonable from the outside.
IF THIS IS YOUR FIRST IPO
A common version of this question from first-time teams is: “Can we do this in 12 months?” The honest answer is that it is possible and occasionally done, but the risk profile is high. The workstreams most likely to create problems under a compressed timeline are SOX program development, auditor transition to PCAOB standards, and cap table reconciliation. Each of those requires time that cannot simply be bought by adding resources.
Day 1 and post-IPO operations
What does broker connectivity mean and why does it matter?
When a company goes public, shares are held by investors through broker-dealers rather than directly with the transfer agent. Broker connectivity is the system that allows the transfer agent to communicate with those brokers to process trades, dividends, and other corporate actions. Without it, Day 1 trading operations cannot function. This is an operational step that needs to be completed and tested before listing, not configured on the morning of.
What is a corporate action, and what should a new public company expect?
A corporate action is any event that materially affects your outstanding shares. Common examples include dividend payments, stock splits, rights offerings, and share buybacks. For companies in their first year of trading, the most operationally intensive event is often the lock-up expiration, when insiders are first permitted to sell shares. Your transfer agent coordinates the mechanics of these events. Having workflows
established before they are needed means the first time you execute one is not also the first time the process is tested.
IF THIS IS YOUR FIRST IPO
Many first-time issuers are heavily focused on getting the S-1 filed and the offering priced, which is understandable. What often gets less attention is the operational intensity of the first few weeks after listing: shareholder inquiries, trade settlement, lock-up management, and disclosure obligations all begin immediately. Your transfer agent, IR function, and legal team need to be operationally ready before the bell rings, not the week after.
What is an investor relations website and what needs to be live on listing day?
Public companies are required to make certain disclosures accessible to investors, and the IR website is the primary channel for this. It should be live on listing day and include SEC filings, press releases, earnings calendar, governance documents, stock information, and investor contact details. The site also needs to be able to receive and publish material news quickly, since disclosure timing requirements under Regulation FD are strict. Building and testing the IR site well before listing is part of Day 1 readiness, not an afterthought.
