INTRODUCTORY NOTE

As previously announced, on June 14, 2017, Rightside Group, Ltd. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), dated June 13, 2017, with Donuts Inc. (“Parent”) and DTS Sub Inc. (“Purchaser”). Subject to the terms and conditions set forth in the Merger Agreement, Purchaser commenced a cash tender offer (the “Offer”) to acquire all of the shares of the Company’s common stock (the “Shares”) for a purchase price of $10.60 per Share in cash, without interest (the “Offer Price”), subject to applicable tax withholdings.

Following the expiration of the Offer at 12:00 midnight, New York City time, on July 26, 2017 (one minute after 11:59 p.m., New York City time, on July 26, 2017), Purchaser accepted for payment 17,740,054 Shares, representing approximately 92.0% of the issued and outstanding Shares. Purchaser accepted for payment all Shares validly tendered and not withdrawn prior to the expiration of the Offer according to the terms and conditions thereof.

Following the expiration of the Offer, pursuant to the terms of the Merger Agreement, on July 28, 2017, Purchaser was merged with and into the Company (the “Merger”), with the Company continuing as the surviving corporation and a wholly-owned subsidiary of Parent, in accordance with applicable provisions of Delaware law that authorize the completion of the Merger without a vote or meeting of stockholders of the Company.

Item 1.02 Termination of a Material Definitive Agreement.

On July 28, 2017, in connection with the consummation of the Merger, the Company terminated its Credit Agreement, dated as of August 1, 2014 (as amended, the “Terminated Credit Agreement”), by and among the Company, certain subsidiaries of the Company as co-borrowers and guarantors, and Silicon Valley Bank. No obligations were outstanding under the Terminated Credit Agreement, other than a letter of credit that will remain outstanding as a letter of credit under that certain Credit Agreement, dated as of November 7, 2016 (as amended, the “Parent Credit Agreement”), by and among Parent, Silicon Valley Bank and the other lenders party thereto. The Company was not obligated to pay any early termination fees or penalties as a result of the termination.

In connection with the Merger, the Company and certain of its domestic subsidiaries have guaranteed Parent’s obligations under the Parent Credit Agreement, which provides for a secured term loan facility in an aggregate principal amount of $85,000,000, a secured revolving loan facility in an aggregate principal amount of up to $25,000,000, and a letter of credit facility, which is a sublimit of and not in addition to the revolving loan facility, of up to $20,000,000, with the Parent’s obligations under the Parent Credit Agreement secured by a pledge of a security interest in substantially all of the assets of Parent. The guarantees are supported by a pledge of a security interest in substantially all of the assets of each subsidiary that is a guarantor.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On July 28, 2017, in connection with the Merger, the Company notified NASDAQ of its intent to remove the Shares from listing on the NASDAQ Global Select Market and requested NASDAQ to file a delisting application on Form 25 with the Securities and Exchange Commission (the “SEC”) to delist and deregister the Shares. The Company also intends to file with the SEC a Form 15 requesting that the Company’s reporting obligations under Section 13 and 15(d) of the Securities Exchange Act of 1934, as amended, be suspended.

Item 3.03. Material Modifications to Rights of Security Holders.

The information set forth in the Introductory Note and under Items 2.01, 5.01 and 5.03 is incorporated by reference herein.

As a result of the Merger, each Share issued and outstanding immediately prior to the Effective Time (other than (i) treasury shares, (ii) Shares held by Parent, Purchaser or any wholly-owned subsidiary of Parent, (iii) Shares held by the Company or any subsidiaries of the Company, and (iv) Shares owned by Company stockholders who have properly preserved their appraisal rights under Section 262 of the DGCL) was cancelled and converted into the right to receive the Offer Price. Holders of Shares that were issued and outstanding prior to the Effective Time ceased to have any rights with respect to such securities, other than their right to receive the Offer Price, as applicable, and they do not have any interest in the Company’s future earnings or growth.

Item 5.01 Changes in Control of Registrant.

The information set forth under the “Introductory Note” and under Item 2.01 is incorporated by reference herein.

As a result of the Purchaser’s acceptance of the Company’s Shares pursuant to the Offer and the Merger, a change in control of the Company occurred, and the Company is now a wholly-owned subsidiary of Parent.

The aggregate value of the acquisition transaction was approximately $213 million. The funds used by Purchaser to purchase the Company were acquired from Parent, from a combination of cash on Parent’s balance sheet and proceeds from the debt financing referenced above under Item 2.03, and cash on the Company’s balance sheet.
