Form S-1 vs. Form S-3

Form S-1 is the general Securities Act registration form. Form S-3 is a shorter form available only to eligible reporting companies.

Form S-1 vs. Form S-3 | Which Registration Statement? | Capital Markets Law Group

A company conducting its first registered offering generally uses Form S-1. An established reporting company may qualify for Form S-3 for shelf offerings, registered directs, at-the-market offerings, or resale registrations. Capital Markets Law Group helps companies determine which form fits the transaction and prepare the filing the form requires.

How Do the Forms Compare?

The two forms cover the same securities laws, but they differ in who may use them and how much disclosure must be written from scratch. The table summarizes the differences.

IssueForm S-1Form S-3
Typical userPrivate company or ineligible reporting companyEligible reporting company
DisclosureFull registration disclosureGreater incorporation by reference
Reporting historyNo prior reporting period generally requiredReporting history and timely filings required
Shelf useMore limited flexibilityCommonly used for shelves
Public floatNot a general eligibility requirementMay affect eligibility and capacity
SEC reviewMay receive full reviewMay also receive review
UpdatingAmendments and supplements as applicableFuture reports may update incorporated disclosure

The practical distinction is preparation. Form S-1 builds the company's public disclosure from the ground up, while Form S-3 rests on an existing record of timely reports. A company whose filings are late or incomplete can lose S-3 eligibility regardless of size, which is why reporting discipline matters as much as the float test.

When Is Form S-1 Used?

Form S-1 may be used for:

  • Initial public offerings
  • Direct public offerings
  • Primary capital raising
  • Resale registrations
  • Going-public transactions
  • Offerings by companies ineligible for Form S-3

When Is Form S-3 Used?

An eligible company may use it for:

  • Shelf registration
  • Registered direct offerings
  • At-the-market offerings
  • Underwritten offerings
  • Resale registrations
  • Debt or preferred offerings

What Is the Baby-Shelf Limitation?

A company with a public float below the specified thresholds may be limited in the amount it can sell under specified Form S-3 instructions during a rolling 12-month period. The calculation should be reviewed before each offering.

What Are the Eligibility Benchmarks?

Form S-3 availability depends on reporting status and public float. A company may qualify when its public float is $75 million or more, and a company whose float is below that level may still qualify through defined alternative conditions tied to reporting history. A company whose float reaches $75 million after the registration statement becomes effective becomes subject to the one-third limit on primary sales rather than the full baby-shelf limit. A company with $700 million or more in public float can sell without the float-based limit.

The calculation should be confirmed before each offering, because float changes with the share price.

Is Form S-3 Always Faster?

It may be more efficient, but timing still depends on eligibility, reporting status, shelf status, offering structure, exchange requirements, SEC review, and auditor involvement.

Frequently Asked Questions

Can a Company Use Form S-3 Immediately After Going Public?

Usually not. Applicable reporting-history requirements must be satisfied.

Can a Company Lose Form S-3 Eligibility?

Yes. Late filings, deficiencies, public-float changes, or other issues may affect availability.

Can Selling Shareholders Use Form S-3?

An eligible issuer may use Form S-3 for qualifying resale registrations.

Does Form S-3 Eliminate SEC Review?

No.

Can a Company Have Both an S-1 and an S-3 Effective?

Potentially, depending on the transactions and registered securities.

What Is the One-Third Limitation?

A company whose public float is below $700 million may be limited under specified Form S-3 instructions to primary sales of up to one third of its public float in any 12-month period. The limitation applies to the registered form and should be checked before an offering is priced.

How Does Delinquent Reporting Affect Form S-3?

Form S-3 eligibility requires the company to have filed all required Exchange Act reports during the applicable period. A company that is delinquent generally cannot use Form S-3 until the required reports are filed, which is why remediation of delinquency is often the first step toward restoring an offering program.
