S-1 vs DRHP: US and India IPO filings
On S-1 vs DRHP, the two are the pre-IPO disclosure documents of the United States and India. An S-1 is the registration statement a US company files with the Securities and Exchange Commission (SEC) before an IPO. A DRHP, or draft red herring prospectus, is the equivalent an Indian company files with SEBI. Both force a private company to open its books before it sells shares to the public. This guide compares S-1 vs DRHP so you know what each one is and how the two processes differ. It is not investment advice.
Definition
An S-1 versus a DRHP
are pre-IPO disclosure documents in two markets. The S-1 is a US company's registration statement filed with the SEC under the Securities Act of 1933. The DRHP is an Indian company's draft prospectus filed with SEBI under the ICDR Regulations. Same purpose, different regulators and steps. Source: SEC, SEBI.
What is the S-1?
An S-1 is filed with the SEC before a US company sells shares to the public. It contains a prospectus covering the business, risk factors, use of proceeds, and audited financials. The company amends it as S-1/A in response to SEC comments, and the SEC must declare the registration effective before any shares are sold. The final priced prospectus is filed as a 424B.
What is the DRHP?
A DRHP is filed with SEBI when an Indian company plans a book-built IPO. It carries the same kind of disclosure: business, risks, financials, and the objects of the issue. SEBI reviews it and issues observations, and the public gets a comment window. The company then files a red herring prospectus with the price band, and a final prospectus with the Registrar of Companies.
How do the two IPO filings compare?
The disclosures rhyme; the machinery differs.
| What to check | S-1 (United States) | DRHP (India) |
|---|---|---|
| Regulator | SEC | SEBI |
| Governing rules | Securities Act of 1933 | SEBI ICDR Regulations |
| Filed on | EDGAR | SEBI website and exchanges |
| Green light | SEC declares it effective | SEBI issues observations, then RHP |
| Final price | In the 424B prospectus | In the red herring prospectus |
| Approval? | No, disclosure only | No, disclosure only |
Disclosure, not approval

Frequently asked questions
What is the difference between an S-1 and a DRHP?
An S-1 is the pre-IPO registration statement a US company files with the SEC under the Securities Act of 1933. A DRHP is the draft red herring prospectus an Indian company files with SEBI under the ICDR Regulations. Both open a company's books before an IPO, in different jurisdictions. Source: SEC, SEBI.
Does either filing mean the IPO is approved?
No. An S-1 must be declared effective by the SEC before shares are sold. A DRHP draws SEBI observations, after which the company files a red herring prospectus with the price band. Neither the S-1 nor the DRHP is an approval or endorsement of the offering. Source: SEC, SEBI.
Where is each filing published?
An S-1 is filed on the SEC's EDGAR system. A DRHP is published on SEBI's website and the stock exchanges, and usually on the lead bankers' sites. Both are free to read. Source: SEC EDGAR, SEBI.
Do the S-1 and DRHP contain the same information?
Broadly similar disclosures: business, risk factors, use of proceeds, management, and audited financials. The structure and regulator differ, and the DRHP typically omits the final price until the later red herring prospectus. Source: SEC, SEBI ICDR Regulations.
