Seasoned equity offering

 ( Corporate Finance ) 

A seasoned equity offering ( SEO) or capital increase is a new equity issued by an already publicly traded company. Seasoned offerings may involve shares sold by existing shareholders (non-dilutive), new shares (dilutive), or both. If the seasoned equity offering is made by an issuer that meets certain regulatory criteria, it may be a shelf offering.
