Introduction
Once the working group files an S-1 with the SEC, the document enters a structured review process that runs in parallel with continued working-group preparation. The review is the SEC's mechanism for ensuring the registration statement contains the disclosures investors and the law require, and it shapes the final document that becomes effective. The JOBS Act of 2012 introduced an alternative pathway for emerging growth companies that submits drafts confidentially before any public filing, and subsequent reforms extended substantial portions of the EGC pathway to all issuers. This article walks through how the review process actually works, what the comment letters look like, how the EGC pathway differs from the traditional public review, and the timing rules that govern when an issuer can launch a roadshow and when the registration becomes effective.
Inside the Division of Corporation Finance Review
The SEC's Division of Corporation Finance reviews registration statements through teams organized by industry assignment groups. A software issuer's S-1 goes to a software-specialist review team; a healthcare issuer's S-1 goes to a healthcare-specialist team. Each review team includes accountants, attorneys, and disclosure specialists who scrutinize the document collectively.
The Review Timeline
The initial SEC comment letter typically arrives 30 to 35 days after the first submission for traditional public filings, or 30 days after the first public filing for issuers in the EGC confidential review pathway. The letter contains 30 to 60 numbered comments organized by section, with each comment requiring either a substantive disclosure change or a written explanation of why no change is needed.
Categories: Accounting, Disclosure, Legal
Comments range across several categories. Accounting comments cover revenue recognition, segment reporting, and pro forma constructions. Disclosure comments cover risk factor specificity, MD&A completeness, and use-of-proceeds clarity. Legal comments cover Form S-1 compliance, exhibit completeness, and securities-law-specific disclosures. Each comment cites the rule or expectation underlying it.
The JOBS Act EGC Confidential Pathway
The JOBS Act of 2012 created Section 6(e) of the Securities Act, which allows emerging growth companies to submit draft registration statements (DRS) confidentially to the SEC before making any public filing. The mechanism is now used by the vast majority of US IPO candidates because most qualify as EGCs.
Submission, Review, and Public Conversion
The issuer submits the first DRS to the SEC through EDGAR but marks the submission as a draft. The SEC reviews the DRS and issues comment letters in the same way as a public filing, but the DRS itself remains nonpublic. The issuer can iterate through one or more rounds of comments while the document stays confidential. When the issuer is ready to go public, the working group makes a public filing that includes the registration statement and all prior DRS submissions and SEC correspondence.
- Draft Registration Statement (DRS)
A nonpublic draft of a registration statement submitted to the SEC for confidential review under Section 6(e) of the Securities Act. The DRS goes through the same comment-letter cycle as a public filing, but the document and SEC correspondence remain confidential until the issuer publicly files. Originally available only to emerging growth companies under the JOBS Act, the DRS pathway has been expanded by SEC policy to cover virtually any first-time registrant. Most US IPO candidates now use the DRS pathway as the standard route to filing.
The 15-Day Public Filing Rule
The working group must publicly file the registration statement at least 15 days before launching a roadshow. This rule, originally 21 days under the JOBS Act and reduced to 15 days under the Fixing America's Surface Transportation (FAST) Act, gives investors a minimum window to review the registration statement before the roadshow begins. The rule also means the working group needs to have completed enough of the SEC review to be comfortable going public 15 days before the planned launch.
Extension to Non-EGC Issuers
The SEC has progressively expanded confidential review beyond EGCs. By 2025, virtually any first-time issuer (including foreign private issuers and registrants who are not technically EGCs) can use the confidential review pathway for their initial registration statement. The expansion reflects the SEC's recognition that confidential review increases the number of issuers willing to file by reducing the cost of an unsuccessful attempt.
Form F-1 and Foreign Private Issuer Status
Non-US issuers register with the SEC on Form F-1 rather than Form S-1, and the FPI designation drives a structurally different reporting regime. The distinction comes up in every cross-border IPO and is a frequent ECM interview topic.
Determining FPI Status (Rule 405 / Rule 3b-4)
The FPI test under Securities Act Rule 405 (and Exchange Act Rule 3b-4) has two prongs. The shareholder test: an FPI is any foreign issuer (other than a foreign government) with 50 percent or less of its outstanding voting securities held of record by US residents. The business contacts test: an issuer that fails the shareholder test still qualifies as an FPI if it has none of the following: (1) a majority of executive officers or directors who are US citizens or residents, (2) more than 50 percent of its assets located in the US, or (3) business administered principally in the US. Initial FPI status is determined within 30 days of filing the first registration statement; ongoing reporting issuers reassess annually as of the last business day of the second fiscal quarter.
Form F-1 vs Form S-1 Mechanics
Form F-1 is the FPI equivalent of Form S-1 with adapted disclosure requirements: reduced executive-compensation disclosure (aggregate rather than individual, exempt from CD&A), no SOX 404(b) auditor attestation during EGC transition, and the option to present financials under IFRS as issued by the IASB without US-GAAP reconciliation. Home-country accounting is permitted but typically requires US-GAAP reconciliation.
Ongoing Reporting Differences
After listing, FPIs file annual reports on Form 20-F (due 120 days after fiscal year end versus 60-90 days for domestic 10-Ks) and furnish material interim disclosures on Form 6-K (rather than 10-Q and 8-K). FPIs are also exempt from Section 14 proxy rules and Section 16 short-swing-profit rules. The reduced burden is one of the principal reasons large non-US issuers prefer FPI status when the structural tests permit.
- Foreign Private Issuer (FPI)
A non-US issuer that meets the SEC's two-prong test under Rule 405: 50 percent or less of voting securities held of record by US residents, or (if the shareholder test fails) no majority of US-resident officers/directors, no majority of US-located assets, and no US-principal business administration. FPIs file Form F-1 for IPO registration, Form 20-F for annual reports, and Form 6-K for interim disclosures, with reduced executive-compensation, internal-controls, and proxy-rule burdens versus domestic Form S-1 / 10-K / 10-Q filers.
The Comment Cycle in Practice
After the first comment letter, the working group goes through a series of cycles that progressively narrow the open issues until the SEC clears the registration for effectiveness.
Drafting the Response, Amendment, and Subsequent Rounds
The working group splits comments across owners (counsel for legal and disclosure comments, the audit firm for accounting, the CFO for MD&A and KPIs, bankers for market-related comments). The S-1/A amendment incorporating disclosure changes is filed at the same time as the response. The SEC's second comment letter usually arrives 15-20 days after the first response and is shorter; most deals clear effectiveness after two to three rounds, with complex deals running through four or five. Total time from first submission to effectiveness typically runs 75-120 days.
The Effectiveness Decision
The SEC formally declares the registration statement "effective" once disclosure complies with applicable rules. Effectiveness is procedural rather than substantive: the SEC does not certify accuracy or offering success, only disclosure compliance. After effectiveness, the issuer can launch the roadshow and price the offering.
- Effectiveness (SEC Declaration of Effectiveness)
The formal SEC action declaring that a registration statement may be used for the offering. The Division of Corporation Finance issues effectiveness once it is satisfied that the disclosure complies with applicable securities law. Effectiveness is procedural rather than substantive: the SEC does not certify that the disclosure is accurate or that the offering will succeed, only that it complies with disclosure requirements. After effectiveness, the issuer can price the offering and shares can be sold to investors. Effectiveness is one of the discrete legal triggers around which the entire IPO calendar is built.
| Phase | Timing from first submission | Key milestone |
|---|---|---|
| First comment letter | 30-35 days | SEC raises 30-60 numbered comments |
| First S-1/A amendment | 45-60 days | Issuer files response and amendment |
| Second comment letter | 60-75 days | Smaller, focused comment set |
| Second/third amendments | 75-105 days | Additional response cycles |
| Effectiveness | 90-120 days | Registration goes effective; roadshow can launch |
| Pricing amendment and pricing | Ongoing | Final amendment incorporates pricing |
The Banker's Role in the Review
The SEC review is primarily a counsel-led workstream, but the bankers contribute meaningfully to specific aspects.
Market-Related Comments
When SEC comments touch on the equity story, peer benchmarking, or market positioning, the bankers contribute the perspective on how investors and the market read the issuer. This input shapes the response and often the amendment language. The bankers' market view is especially useful when the SEC questions the basis for KPI disclosure or competitive position claims.
Pricing-Related Disclosures
The pricing amendment that incorporates the indicative price range, offering size, and underwriter syndicate is owned jointly by counsel and the bankers. The amendment is typically the shortest of the S-1/A amendments but triggers SEC review of pricing-specific disclosures.
SEC review is the formal mechanism that converts a draft S-1 into a public-effective document; everything else in the IPO calendar gates on the moment effectiveness is declared. Running in parallel is the marketing workstream that shapes how the document gets received once it is public, which is building the equity story.
