ITEM 1.01
On March 9, 2021, Rimini Street, Inc. (“we,” “us,” “our” or the “Company”) and certain stockholders of the Company (collectively, the “Selling Stockholders”) entered into an underwriting agreement (the “Underwriting Agreement”) with Craig-Hallum Capital Group LLC, as underwriter (the “Underwriter”), relating to the offer and sale of an aggregate of 7,750,000 shares of common stock, par value $0.0001 per share, of the Company, all of which shares are to be issued and sold by the Company, at a public offering price of $7.75 per share. Pursuant to the Underwriting Agreement, the Selling Stockholders granted the Underwriter an option to purchase up to an additional 1,126,500 shares at the public offering price less the underwriting discount. On March 9, 2021, the Underwriter delivered notice of its exercise in full of the option. The offering relating to the shares sold by the Company is being made pursuant to the Registration Statement on Form S-3 (File No. 333-228322) (the “Registration Statement”), including the accompanying prospectus, dated November 21, 2018, and as supplemented by a prospectus supplement dated March 11, 2021, to be filed with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”), and the offering relating to the shares sold by the Selling Stockholders is being made pursuant to the Registration Statement on Form S-3 (File No. 333-228320) (the “Resale Registration Statement”), including the accompanying prospectus, dated November 21, 2018, and as supplemented by a prospectus supplement dated March 11, 2021, to be filed with the Commission pursuant to the Securities Act.

The Company will not receive any proceeds from the sale of any shares by the Selling Stockholders, which will be approximately $8.57 million as the Underwriter has exercised in full the option to purchase up to the additional 1,126,500 shares from the Selling Stockholders, after deducting the underwriting discount and commissions.

(the “ASP Selling Stockholders”). Mr. Anthony Bonchristiano is an affiliate of the GP Selling Stockholders and is a member of or our Board of Directors. Mr. Robin P. Murray is a partner of an affiliate of the ASP Selling Stockholders and is a member of our Board of Directors.
