From Private to Public: The IPO Readiness Guide

A cleaned, structured rich-text version of Connor Group’s IPO Readiness Guide. This version reorganises the PDF into a more readable format, reduces repetition, and turns visual callouts into usable headings, bullet lists, and checklists.

Executive summary

An IPO is not simply a financing transaction. It is a company-wide operating model shift: financial reporting, controls, systems, governance, stakeholder management, and investor communication all need to mature before the company enters the public markets.

The strongest theme running through the guide is that companies should begin behaving like public companies before they are public. That means tightening the close process, preparing PCAOB-ready financials, building SOX-ready controls, improving systems, rehearsing investor communication, and defining KPIs that can stand up to public scrutiny.

1. IPO overview and readiness landscape

The IPO is a transformation, not just a transaction

Going public reshapes how a company operates, governs itself, reports performance, communicates with stakeholders, and is held accountable. A successful IPO requires discipline, infrastructure, reliable reporting, and operating rigor that will continue long after the offering closes.

Listing route options

The right path to market affects timeline, cost, compliance obligations, shareholder liquidity, and long-term investor appeal.

• Traditional IPO: Shares are issued to underwriters, who market and sell them to public investors. This remains the most common route for broad institutional capital raising.
• Direct listing: Existing shareholders sell into the market without a traditional underwritten capital raise. This is usually better suited to companies with strong brand recognition and liquidity.
• SPAC transaction: A merger with a special purpose acquisition company can speed access to public markets, but can introduce valuation volatility and transaction complexity.
• Reverse merger: A private company merges with an existing public entity. This may suit smaller companies but can bring legacy risks from the public shell.

SEC filings and regulatory framework

Regulatory readiness is central to IPO preparation. Companies need to identify disclosure, financial reporting, tax, governance, and legal gaps early enough to remediate them before they delay the transaction.

• Form S-1 is often required and includes historical financial performance, risks, business disclosures, and offering details.
• Emerging Growth Company status can reduce certain disclosure burdens, including in some cases requiring two years of audited financial statements rather than three.
• Public companies must prepare for recurring Form 10-Q and Form 10-K reporting cycles.
• Material contracts and financial data may need to be disclosed in detail while still protecting sensitive commercial information.

Key stakeholders in an IPO

IPO execution requires a coordinated internal and external team. Management needs to clearly understand its role, even where advisors are experienced and know the process well.

• Company leadership: The CEO, CFO, and leadership team own the growth story, investor confidence, readiness decisions, and internal alignment.
• Underwriters and bankers: Advise on valuation, pricing, investor appetite, offering structure, roadshow strategy, and post-issuance stabilisation.
• Legal counsel: Guides SEC compliance, risk disclosures, equity structure, ownership disclosures, and governance documentation.
• Auditors and accounting advisors: Support PCAOB-ready financials, GAAP or IFRS compliance, accounting judgements, controls, and disclosure quality.
• Investors and analysts: Shape market expectations. Early credibility with these audiences can strengthen investor buy-in during and after the offering.

Common cross-functional decisions

• Which financial periods should be included in the S-1.
• How pro forma assumptions should be built, reviewed, and disclosed.
• How equity structures, convertible securities, and voting rights should be presented.
• Which risks should be disclosed and how strongly they should be emphasised.
• How management ownership, compensation, and related-party data should be disclosed.
• Whether internal controls and governance structures are mature enough for public scrutiny.

2. Preparing for life as a public company

IPO readiness should be phased. The guide presents four major preparation windows: early readiness, investor focus, regulatory and risk management, and final execution.

Phase 1: Early readiness preparation

Start well before the transaction. The company should assess whether the IPO is viable, whether timing is favourable, and whether the business has the systems, processes, controls, and people needed for public-market scrutiny.

• Assess growth profile, funding needs, valuation expectations, market conditions, macroeconomic factors, and geopolitical risks.
• Start producing PCAOB-compliant financial statements.
• Begin operating to public-company reporting timelines, including quarterly close cycles.
• Recruit board members with public-company experience.
• Document and test critical internal controls.
• Align executives, shareholders, and advisors around IPO objectives and timing.

Phase 2: Investor focus, 12-18 months before IPO

• Benchmark financial performance against public peers.
• Address gaps in KPIs, forecasts, and financial projections.
• Build management presentations, an investment thesis, and Wall Street-style financial models.
• Draft MD&A thinking around the preferences and questions of investors.
• Begin conversations with underwriters, analysts, and prospective investors.
• Formalise investor relations protocols and transparency objectives.
• Solidify governance and reporting systems ahead of investor diligence.

Phase 3: Regulatory and risk management, 6-12 months before IPO

• Monitor market, geopolitical, and recession risks that may affect valuation or timing.
• Develop contingency plans for SEC review delays.
• Prepare for SOX compliance and any other relevant frameworks.
• Prepare responses for high-profile corporate developments during the IPO window.
• Build a crisis communication plan for reputational risks.

Phase 4: Execution, final 6 months

• Submit the registration statement to the SEC, often confidentially, with complete and accurate data.
• Prepare detailed responses and disclosures for expected SEC comments, especially around complex accounting issues.
• Finalise the registration statement and roadshow materials.
• Rehearse presentations to institutional investors.
• Formalise audit committees and establish investor relations capacity.
• Collaborate with underwriters on pricing and share allocation.
• Prepare for consistent, high-quality post-IPO earnings reporting and transparent market communication.

Practical principle

The IPO is the start of public-company life, not the end of the road. Readiness work should therefore build repeatable capabilities, not merely complete transaction tasks.

3. IPO planning and management

Create a dedicated IPO project management office

A strong PMO gives structure to a complex, cross-functional transaction. It should coordinate timelines, stakeholders, deliverables, and communication.

• Coordinate timelines: Maintain a comprehensive IPO plan covering readiness assessments, drafting, SEC submissions, roadshow preparation, and launch milestones.
• Manage stakeholders: Ensure participation from finance, legal, IT, HR, auditors, underwriters, legal counsel, and other advisors.
• Track deliverables: Monitor action items, deadlines, bottlenecks, reviews, and dependencies.
• Ensure communication: Keep functions aligned to avoid missed deadlines, duplicated effort, and misaligned priorities.

Decision-making framework

• Formalise governance and oversight, including board and advisor input.
• Prioritise risks and maintain escalation paths for compliance gaps, delays, or emerging issues.
• Make ownership of decisions explicit so dependencies do not stall the IPO timetable.

Resource allocation

• Expand internal teams in accounting, legal, compliance, investor relations, IT, and financial planning where needed.
• Use technology to streamline reporting, compliance tracking, close processes, and collaboration.
• Engage advisors early on financial reporting, SOX readiness, investor relations, tax, legal, and systems implementation.

Practice operating as a public company

• Run mock earnings calls and mock 10-Q processes.
• Accelerate close timelines; the guide references a 10-day month-end close as an example public-company target.
• Begin implementing and testing SOX controls well in advance.
• Define the company value proposition clearly, but avoid overpromising targets or KPIs that are difficult to sustain.

4. Understanding the SEC Form S-1 filing process

What the S-1 does

The S-1 registration statement is central to the IPO process. It gives investors a detailed view of the company’s financial health, business operations, strategy, risks, use of proceeds, and capital structure.

Core S-1 components

• Prospectus summary: A concise overview of the company, its mission, operations, strengths, and key risks.
• Business overview: A deeper explanation of operations, segments, competitive positioning, intellectual property, and growth strategy.
• Financial statements: GAAP-compliant financials, including balance sheet, income statement, cash flow statement, and shareholder equity.
• MD&A: Management’s Discussion and Analysis of trends, market influences, developments, and planned use of IPO proceeds.
• Risk factors: A structured explanation of market, operational, regulatory, financial, and company-specific risks.
• Use of proceeds: How the company expects to allocate IPO proceeds, such as R&D, debt repayment, or expansion.
• Offering price methodology: How the IPO price is determined and what factors influence valuation.
• Dilution: How the offering affects existing shareholders and post-IPO ownership percentages.

Emerging Growth Company benefits

The JOBS Act created the EGC designation to reduce compliance burdens for qualifying growth companies. The guide identifies eligibility factors including revenue below $1.235 billion, not issuing more than $1 billion in non-convertible debt over three years, and meeting other JOBS Act criteria.

• Confidential draft S-1 submissions before public filing.
• Reduced financial disclosures, typically two years of audited financial statements rather than three.
• Simplified executive compensation disclosures.
• Ability to test the waters with institutional investors before formal filing.

Financial statement requirements

• EGCs may provide two years of audited financials plus relevant interim financials.
• Non-EGCs generally provide three years of audited financials plus unaudited interim periods.
• Financials can become stale if they exceed age limits; the guide references 135 days from the latest balance sheet as a typical stale-date threshold.
• Companies with acquisitions, divestitures, restructuring, or complex tax issues may need supplemental disclosure.

Typical S-1 preparation flow

1. Build the drafting team: management, underwriters, underwriter counsel, company counsel, accounting advisors, and auditors.
2. Define ownership of S-1 sections, review cycles, and drafting sessions.
3. Draft the registration statement and supporting financial disclosures.
4. Run legal, accounting, auditor, and management reviews.
5. Submit confidentially where eligible, then respond to SEC comments.
6. Update stale financials and disclosures as needed.
7. File publicly, launch roadshow preparation, and finalise pricing and offering materials.

5. Six technical accounting issues to address before IPO

The guide highlights six accounting areas that commonly create IPO delays, SEC comments, audit complexity, or restatements if not addressed early.

1. Revenue recognition

Revenue is a central investor focus and often a source of complex judgement. Companies should ensure ASC 606 analysis is robust, documented, and aligned with how contracts operate in practice.

• Analyse performance obligations and when they are satisfied.
• Document variable consideration, discounts, returns, and customer incentives.
• Prepare disaggregated revenue disclosures that explain the drivers of growth.
• Explain contract balances such as deferred revenue and contract assets.
• Make future performance obligations clear enough for investors to understand revenue visibility.

2. Equity and debt arrangements

Pre-IPO companies often have preferred stock, convertible debt, SAFEs, warrants, and other instruments with conversion, redemption, or contingent features. Misclassification can create reporting delays or restatements.

• Understand all conversion, redemption, contingent, and non-contingent terms.
• Evaluate what happens to instruments at IPO effectiveness.
• Consider the accounting effects of secondary transactions before IPO.
• Analyse debt refinancings or restructurings carefully because modification versus extinguishment conclusions can materially affect results.

3. Segment reporting

ASC 280 requires public-company segment reporting based on how management views the business. Companies must identify operating segments, the Chief Operating Decision Maker, discrete financial information, and whether segments can be aggregated.

• Determine who or what qualifies as the CODM in practice.
• Assess which financial information is actually reviewed for resource allocation and performance assessment.
• Document judgements around aggregation of operating segments into reportable segments.
• Consider shared costs, corporate overhead, and cross-segment transactions.

4. Earnings per share

ASC 260 EPS calculations require detailed modelling of shares, securities, participating instruments, stock splits, conversions, and equity restructuring events.

• Identify all securities that affect basic or diluted EPS.
• Model weighted-average shares for issuances, repurchases, splits, and conversions.
• Allocate earnings between common shareholders and participating securities where required.
• Apply if-converted and treasury stock methods accurately.

5. Cheap stock

Cheap stock refers to equity awards granted before an IPO at valuations significantly below the expected offering price. These awards receive scrutiny from auditors, investors, and the SEC.

• Determine fair value at grant date using current evidence rather than stale 409A valuations.
• Maintain board approvals, valuations, business context, and timing rationale for grants.
• Reconcile pre-IPO valuation assumptions with the expected IPO price.
• Be cautious with large grants, repricing, or modifications within 6-12 months of IPO.
• Avoid equity grants during valuation uncertainty or immediately before roadshows unless strongly justified.

6. Pro forma financial statements

Pro forma statements simulate the impact of IPO-related transactions, acquisitions, recapitalisations, debt settlements, or capital structure changes. They must be factually supportable and directly attributable to the transaction.

• Model conversion of preferred stock, warrants, or convertible debt into common equity.
• Assess dilution impact and retrospective EPS effects.
• Reflect settlement of debt or extinguishment costs where applicable.
• Apply ASC 805 and Regulation S-X where acquisitions affect the model.
• Exclude speculative synergies or unsupported adjustments.
• Understand anti-dilution clauses and their impact on pro forma statements.

6. Close and reporting at public company standard

A public-ready close process needs to produce accurate, reliable, and timely financial results. This builds investor confidence, supports regulatory compliance, and reduces audit adjustment risk.

What needs to change

• Move from scattered 10-40 day or incomplete closes to a consistent close process, with month-end reconciliations, journal entries, and key analyses completed on time.
• Integrate sub-ledger entries, account reconciliations, journal postings, and management reviews into the close process.
• Replace fragmented systems, manual spreadsheets, and decentralised accounting with integrated systems and automation where possible.
• Standardise accounting policies across the organisation.
• Build management reporting packs with reconciliations, variance analysis, and performance metrics.
• Synchronise tax provisioning, MD&A drafting, finance review, and external reporting timelines.
• Provide analysis by sales channels, geography, product lines, or other dimensions relevant to public investors.

Common barriers

• Limited personnel trained in public-company reporting.
• Outdated systems that cannot produce reliable results without manual intervention.
• Organisational resistance to reducing spreadsheet dependency.
• Insufficient account analysis documentation.
• Lack of integrated review layers before audit and filing.

7. Internal controls and SOX maturity

Controls must evolve, not just exist

The guide argues against a check-the-box view of internal controls. IPO-ready controls should be embedded in business processes, scalable, documented, tested, and aligned with public-company expectations.

Controls maturity journey

• Uncontrolled: Few defined or repeatable processes. Outcomes are unreliable and often erroneous.
• Emerging: Some defined controls exist, but they are not yet consistent or comprehensive.
• Established: Defined and consistent controls cover key finance processes and systems.
• Managed: Controls are validated, outcomes are reliable, and control performance is monitored.
• Strategic and optimised: The control environment is streamlined, automated where possible, and integrated into strategic processes with ongoing monitoring.

What IPO-ready controls look like

• Standardised, scalable processes for key accounting, reporting, and operational activities.
• Documented policies and procedures that are actually followed.
• Automation and system controls where possible to reduce manual reliance.
• Periodic testing and validation of control performance.
• Training and accountability across the organisation.
• Controls prioritised around high-risk areas such as revenue, close processes, and IT general controls.
• Scalable design rather than overly complex control structures.

Material weaknesses in ICFR

Material weaknesses can affect the IPO journey by increasing regulatory scrutiny, damaging investor confidence, delaying audits, or affecting pricing.

• Common themes include lack of accounting expertise, weak segregation of duties, over-reliance on a small finance team, deficient risk assessment, manual spreadsheet-driven processes, and ineffective control design or execution.
• The S-1 should disclose the weakness, potential impact, remediation plan, and timeline if unresolved.
• Early preparation helps remediate weaknesses before disclosure, reduce PCAOB audit surprises, and build confidence in reporting processes.

SOX requirements

• SOX 404(a): Management must establish, maintain, and assess internal controls over financial reporting. External auditor attestation is not mandatory under 404(a).
• SOX 404(b): An independent auditor must attest to the effectiveness of internal controls. This brings greater scrutiny, higher documentation needs, and more formalised testing expectations.
• SOX 302: CEO and CFO certify the completeness and reliability of quarterly and annual filings.
• SOX 906: CEO and CFO certify financial statement fairness and face heightened liability for knowingly inaccurate or misleading reports.

EGC SOX timeline principle

EGCs can be exempt from SOX 404(b) auditor attestation while they retain EGC status. However, the guide emphasises that companies should prepare early for the eventual transition to 404(b), because external attestation significantly increases documentation, evidence, and testing demands.

8. Technology readiness for IPO

Technology readiness supports reporting integrity, controls maturity, scalable operations, data-driven decisions, and compliance. The goal is to move from manual, fragmented processes to integrated systems that can support public-company scrutiny.

Core technology capabilities

• Reliable reporting: Systems should produce consistent, error-free data, regulatory-compliant reporting, streamlined data collection, and real-time access for stakeholders.
• Robust controls environment: Technology should support approval workflows, automated audit trails, anomaly detection, policy monitoring, and reduced manual intervention.
• Scalable tools: ERP, HRIS, CRM, procurement, iPaaS, and data warehouse solutions should handle growth in transaction volume, headcount, geography, and operational complexity.
• Data-driven decisions: Dashboards, analytics, machine learning, and AI can support forecasting, budgeting, risk analysis, and leadership visibility.

Technology readiness roadmap

1. Build a tailored technology readiness roadmap aligned to operational needs and IPO objectives.
2. Conduct readiness assessments across financial systems, controls, integrations, reporting accuracy, and scalability.
3. Define phase milestones such as ERP implementation, automation deployment, process standardisation, and analytics dashboards.

Four levels of technology readiness

• Level 1: Build the foundation: Manual inputs, spreadsheets, limited integration, weak controls, and minimal reporting. Focus on ERP selection, standardised processes, basic integrations, and automation in high-impact areas.
• Level 2: Upgrade financial systems and reporting: Implement systems that improve automation, centralise processes, strengthen controls, and prepare for audit readiness. Consider ERP, data warehouse, internal control design, and AI-enabled features.
• Level 3: Optimise processes and enhance automated controls: Automate integrations between key systems, improve approval workflows, deploy forecasting and budgeting tools, and strengthen reporting for strategic insight.
• Level 4: Automate processes: Move towards real-time dashboards, automated close tools, planning and analysis solutions, generative AI, agent-based workflows, and minimal manual intervention across workflows.

9. Public company KPI readiness

KPIs translate the company’s strategy and operating model into a language investors and analysts can evaluate. They should be selected, defined, controlled, and documented with public-market expectations in mind.

KPI readiness checklist

• Select KPIs that align with strategic goals and industry benchmarks.
• Avoid excessive reliance on non-standard or non-GAAP metrics unless clearly justified.
• Document definitions and formulas consistently.
• Align business leaders around calculations and definitions.
• Explain why each KPI is useful and how management uses it.
• Implement controls, reconciliations, audit trails, and disclosure processes over KPI data.
• Approve and document any changes in KPI calculations over time.
• Lock down prior-period KPIs to preserve comparability.

Industry examples

• SaaS / software: Annual recurring revenue, monthly recurring revenue, churn, customer acquisition cost, expansion revenue, lifetime value. Investors focus on recurring revenue stability, retention, scalability, and efficient growth.
• Manufacturing: Operational yield, inventory turnover, capital expenditure efficiency. Investors look for operational excellence, capacity to scale, and capital discipline.
• Logistics / transportation: Load factor, on-time delivery, fleet utilisation, cost per mile. Investors focus on efficiency, scalability, and cost management.
• FinTech: Total payment volume, CAC, monthly active users, ARPU, transaction success rate, fraud loss as a percentage of revenue. Investors focus on platform adoption, monetisation, risk management, and scalability.
• Telecom / media: Average revenue per user, subscriber net additions, churn, network uptime. Investors focus on subscriber growth, cost management, and service reliability.
• Healthcare services: Patient retention, bed occupancy, utilisation, operational efficiency metrics, and quality indicators. Investors focus on efficiency, scalability, quality of care, and sustainable growth.

Important caution

Although companies can change KPIs over time, investors and analysts may scrutinise changes. Companies should avoid disclosing metrics they are not willing to report consistently in future periods, because disclosed KPIs often become an expected part of ongoing reporting.

10. Conclusion and next steps

The guide’s closing message is that every IPO path is unique, but readiness can be assessed systematically across operations, financials, governance, controls, systems, and investor communication. Companies that prepare early are better positioned not only for a strong market debut, but for lasting performance as public entities.

Readiness questions leadership should be able to answer

• Can we close quickly, accurately, and consistently?
• Are our financial statements PCAOB-ready and free of avoidable technical accounting surprises?
