Follow-On Offerings

A follow-on offering is any sale of additional shares by a company that is already public. Follow-ons can be primary, where the company sells new shares, or secondary, where existing holders sell, and can be marketed or done overnight.

Key Takeaways

• Follow-ons use shelf registrations for speed.
• Primary offerings dilute; secondary ones do not fund the company.
• Discounts are typical.
• Insider sales are read as a signal.

01

Types

A primary follow-on raises money for the company and dilutes holders. A secondary follow-on lets insiders or investors sell and does not provide company proceeds. Many deals combine both.

02

How They Work

Companies often use a shelf registration, such as Form S-3 for eligible issuers, to sell quickly. Bought deals and overnight offerings are priced at a discount to the last trade after the market closes.

03

What to Watch

Pricing discount, size relative to float, use of proceeds, and insider selling are key signals. Large secondaries after lock-up expiry often pressure the stock.
