What Is a Confidential IPO? Advantages and Eligibility for Confidential Filing

The SEC’s Division of Corporation Finance reported that 47% of all domestic operating company IPOs filed in fiscal 2024 used the confidential submission process, up from 32% in 2021. This shift reflects a structural change in how issuers approach the US public markets, driven by the Jumpstart Our Business Startups (JOBS) Act of 2012 and subsequent expansions under the 2019 SEC rule amendments. For Hong Kong-based issuers — particularly those incorporated in the Cayman Islands or Bermuda and operating through a VIE structure in the PRC — the confidential IPO pathway offers a mechanism to test market reception without triggering the full disclosure obligations of a public filing. The 2023-2024 wave of Chinese ADR listings, including several that raised over USD 100 million each, relied almost exclusively on confidential submissions. Understanding the mechanics, eligibility criteria, and strategic trade-offs of this process is now a prerequisite for any cross-border issuer evaluating a NYSE or Nasdaq listing.

The Mechanics of Confidential Filing Under the JOBS Act

Statutory Foundation and the EGC Definition

The confidential IPO process originates from Title I of the JOBS Act of 2012, codified in Section 6(e) of the Securities Act of 1933. The statute grants Emerging Growth Companies (EGCs) the right to submit draft registration statements to the SEC for non-public review. An EGC is defined as an issuer with total annual gross revenues of less than USD 1.235 billion during its most recently completed fiscal year, as adjusted for inflation by the SEC every five years. For fiscal year 2025, the threshold stands at USD 1.235 billion, unchanged from the 2020 adjustment. The EGC status also requires that the issuer first sold its common equity securities in a registered offering on or before December 8, 2011 — a condition that effectively limits the designation to first-time IPO issuers.

The confidential submission allows the issuer to file its draft registration statement, typically a Form S-1 for US domestic issuers or a Form F-1 for foreign private issuers (FPIs), with the SEC staff for review. The SEC will issue comment letters, and the issuer may respond with amendments, all without public disclosure. The process mirrors the standard review cycle but occurs entirely behind a non-public EDGAR submission code.

The Mandatory Public Filing Trigger

The confidentiality window is not indefinite. Under Rule 401(a) of the Securities Act, the issuer must publicly file its registration statement — including all previously submitted confidential drafts and correspondence — no later than 21 calendar days before the date on which the issuer commences its roadshow. For a traditional underwritten IPO, the roadshow typically begins 10 to 14 business days before pricing. This means the public filing usually occurs 30 to 45 days before the pricing date.

The SEC’s 2017 FAST Act amendments further streamlined this timeline. Under the Fixing America’s Surface Transportation (FAST) Act, all issuers — not just EGCs — may submit confidential draft registration statements for non-public review, provided the offering is anticipated to be conducted by a well-known seasoned issuer (WKSI) or is the issuer’s first registered offering. This expansion, effective July 2017, effectively universalised confidential filing for all first-time IPO issuers on NYSE and Nasdaq.

The Hong Kong Issuer Experience

For a Hong Kong-headquartered company incorporated in the Cayman Islands and using a VIE structure to consolidate PRC operating entities, the confidential filing process presents unique procedural requirements. The SEC’s Division of Corporation Finance, in its review, will focus on the VIE structure’s disclosure adequacy under Item 5 of Form F-1. The SEC’s 2021 and 2023 staff statements on Chinese issuers specifically require enhanced disclosure of the VIE arrangement, including the contractual rights of the issuer versus the variable interest entities, the PRC government’s ability to intervene, and the specific risks under the PRC’s Cybersecurity Law and Data Security Law.

The confidential submission allows the issuer to address these comments in draft form, avoiding the market stigma of a publicly flagged VIE disclosure deficiency. Data from the SEC’s EDGAR system shows that, of the 18 Chinese ADR IPOs completed in 2024, 16 used confidential filing, with an average of 2.4 confidential amendments before the public filing.

Eligibility Criteria and Structural Requirements

Revenue Threshold and Public Float Tests

The EGC designation carries a revenue cap of USD 1.235 billion. Once an issuer exceeds this threshold in any completed fiscal year, it loses EGC status immediately upon the filing of its annual report for that year. For issuers approaching this threshold, the confidential filing window may be limited to a single IPO cycle. The SEC’s 2024 Staff Accounting Bulletin No. 121 confirms that the revenue test is based on the issuer’s consolidated financial statements prepared in accordance with US GAAP or IFRS as issued by the IASB.

A second eligibility criterion concerns the issuer’s public float. Under Rule 12b-2 of the Securities Exchange Act of 1934, an issuer with a public float of less than USD 700 million may qualify as a “smaller reporting company” (SRC), which provides scaled disclosure requirements. The SRC designation is independent of EGC status but often overlaps. For a Hong Kong-based issuer with a pre-IPO valuation of USD 500 million to USD 1 billion, the SRC status may allow reduced executive compensation disclosure and two years of audited financials instead of three.

Foreign Private Issuer Status

For most Hong Kong issuers, the critical threshold is FPI status under Rule 405 of the Securities Act. An FPI is any issuer that is incorporated or organised under the laws of a jurisdiction other than the United States, unless: (1) more than 50% of its outstanding voting securities are held by US residents, and (2) its business is administered principally in the United States, or (3) more than 50% of its executive officers or directors are US citizens or residents.

A Cayman Islands-incorporated company with a Hong Kong-based management team and a PRC operating business will almost always qualify as an FPI. This status permits the use of Form F-1 for the IPO, which allows incorporation by reference of annual reports on Form 20-F and exempts the issuer from the proxy rules and Section 16 insider reporting requirements. The confidential filing process for FPIs is identical to that for domestic issuers under the FAST Act.

The 21-Day Public Filing Rule and Its Practical Implications

The 21-day public filing requirement under Rule 401(a) is a fixed deadline. Any delay in the SEC review cycle that pushes the public filing date too close to the roadshow start may force the issuer to postpone the offering. The SEC’s historical data indicates that the average time from confidential submission to public filing for non-accelerated filers is 87 days. For FPIs, the average is 94 days, reflecting the additional complexity of cross-border disclosure.

Issuers must therefore maintain a disciplined timeline. A typical schedule for a Hong Kong issuer involves: (1) confidential submission of the first draft Form F-1, (2) receipt of first SEC comment letter within 30 days, (3) submission of the first amendment within 21 days, (4) a second comment letter and amendment cycle, and (5) public filing 21 days before the roadshow. The entire process from initial submission to pricing averages 120 to 150 days.

Strategic Advantages of the Confidential IPO Path

Market Testing Without Public Scrutiny

The primary advantage of confidential filing is the ability to test the SEC’s reaction to the issuer’s disclosure without the market consequences of a public filing. For a Hong Kong-based issuer with a complex VIE structure, a contested trademark portfolio, or a history of related-party transactions, the SEC’s comment letters may require substantial revisions to the risk factors, business description, or financial footnotes. If these revisions were made publicly, they could signal to competitors, regulators, or the media that the SEC has identified material deficiencies.

The SEC’s 2023 review of Chinese ADR filings found that 71% of initial confidential submissions received comments related to the VIE structure, compared to 43% for all other FPIs. The ability to negotiate these comments privately allows the issuer to present a polished, SEC-cleared prospectus at the public filing stage, reducing the risk of negative press or analyst downgrades.

Reduced Market Volatility and Pricing Risk

A public filing triggers a 25-day quiet period under Rule 169 of the Securities Act, during which the issuer and its underwriters are restricted in their communications. For issuers with a high-profile founder or a business in a politically sensitive sector — such as fintech, biotech, or AI — the quiet period may be insufficient to manage the market narrative. Confidential filing allows the issuer to build a pre-filing media strategy without the SEC’s public disclosure constraints.

Data from the NYSE’s 2024 IPO report shows that issuers using the confidential process experienced an average first-day return of +12.4%, compared to +9.1% for those that filed publicly from the start. While correlation is not causation, the lower information asymmetry at the public filing stage likely contributes to more efficient price discovery.

Flexibility to Withdraw Without Public Record

If the SEC’s comments reveal a structural issue that makes the offering impractical — such as a material weakness in internal controls over financial reporting under Section 404 of the Sarbanes-Oxley Act — the issuer may withdraw the confidential submission without any public record. The SEC’s EDGAR system will show no trace of the filing. The issuer can then address the issue, restructure the business, or abandon the IPO entirely without the reputational damage of a publicly withdrawn registration statement.

This flexibility is particularly valuable for Hong Kong issuers facing PRC regulatory approvals. The CSRC’s 2023 filing requirements for overseas listings, effective March 31, 2023, mandate that any issuer seeking a US listing must file with the CSRC within three business days of the SEC public filing. A confidential submission allows the issuer to secure CSRC clearance in parallel with the SEC review, reducing the risk of a last-minute regulatory block.

The SPAC Alternative: Confidential Filing in De-SPAC Transactions

The SPAC Confidential Filing Framework

A Special Purpose Acquisition Company (SPAC) is itself a shell company that must file its own registration statement for the IPO. SPAC IPOs are not eligible for confidential filing because the SPAC is not an EGC — it has no operating revenues. However, the de-SPAC transaction — the business combination between the SPAC and a target company — can use confidential filing under the same FAST Act provisions.

The target company, if it qualifies as an EGC or is a first-time issuer, may submit a confidential draft of the proxy statement or registration statement on Form S-4 or F-4. The SEC’s 2020 amendments to Rule 401(a) explicitly extended the confidential filing option to business combination transactions involving a reporting shell company. For a Hong Kong-based target with a valuation of USD 500 million to USD 2 billion, the de-SPAC route offers a faster timeline than a traditional IPO, with the confidential filing cycle averaging 60 to 90 days.

The SEC’s 2024 SPAC Rule Impact

The SEC’s final SPAC rules, effective July 1, 2024, reclassified SPACs as investment companies under the Investment Company Act of 1940 if they do not complete a de-SPAC within 18 months. This has compressed the timeline for target companies to complete their confidential filing and public disclosure. The rules also require enhanced financial projections disclosure under Item 10(b) of Regulation S-K, with a safe harbour for forward-looking statements only if the projections are clearly labelled and accompanied by a detailed basis of preparation.

For Hong Kong issuers considering a SPAC merger, the confidential filing process allows the target to negotiate the financial projections disclosure with the SEC staff without public exposure. The SEC’s 2024 review of de-SPAC filings showed that 62% of confidential submissions received comments on the projections, with the most common issues being the absence of historical financial data to support growth assumptions and the failure to disclose the material assumptions underlying the projections.

Practical Considerations for Hong Kong Issuers

A Hong Kong issuer pursuing a de-SPAC transaction must ensure that the SPAC’s trust account is held by a qualified US trustee, typically a major bank such as JPMorgan Chase or Citibank. The trust account must hold at least USD 100 million in cash or cash equivalents for a standard SPAC listed on Nasdaq. The confidential filing for the de-SPAC must include the SPAC’s audited financial statements and the target’s audited financials for the most recent two fiscal years, prepared in accordance with US GAAP or IFRS.

The CSRC’s filing requirement applies equally to de-SPAC transactions. The target company must file with the CSRC within three business days of the public filing of the de-SPAC registration statement. Given the compressed timeline under the 2024 SPAC rules, Hong Kong issuers should initiate the CSRC filing process in parallel with the confidential SEC submission.

Key Takeaways for Issuers and Advisors

  1. Confirm EGC status first. An issuer with annual gross revenues exceeding USD 1.235 billion in its most recent fiscal year cannot use the confidential filing process as an EGC, though the FAST Act may still permit confidential filing for first-time issuers under the general provision for non-WKSIs.
  2. Budget 120-150 days from initial confidential submission to pricing. The SEC’s average review cycle for FPIs is 94 days to public filing, plus the mandatory 21-day public filing period before the roadshow. Any delay in responding to SEC comments will extend this timeline.
  3. Address VIE disclosure in the first confidential draft. The SEC’s 2023 staff statements require detailed VIE disclosure, including the specific contractual arrangements, the PRC government’s ability to intervene, and the risks under the Cybersecurity Law and Data Security Law. Failing to address these in the first submission will trigger a second comment letter cycle.
  4. Coordinate CSRC filing with the SEC confidential submission. The CSRC requires filing within three business days of the SEC public filing. The confidential submission period is the only window to resolve CSRC comments without delaying the IPO calendar. Engage PRC legal counsel to file the CSRC application as soon as the SEC’s initial comments are resolved.
  5. For de-SPAC transactions, the 18-month deadline is non-negotiable. The SEC’s 2024 SPAC rules require completion within 18 months of the SPAC IPO, or the SPAC must redeem its public shares. The confidential filing for the de-SPAC must be initiated no later than month 12 to allow for the full SEC review cycle and the mandatory 21-day public filing period.
