Underwriting Agreement

On June 18, 2015, 8point3 Energy Partners LP (the “Partnership”) entered into an Underwriting Agreement (the “Underwriting Agreement”), by and among the Partnership, 8point3 General Partner, LLC (the “General Partner”), and 8point3 Holding Company, LLC (collectively, the “8point3 Parties”), and Goldman, Sachs & Co. and Citigroup Global Markets Inc., as representatives of the several underwriters named therein (the “Underwriters”), providing for the offer and sale by the Partnership (the “Offering”), and purchase by the Underwriters, of 20,000,000 class A shares representing limited partner interests in the Partnership (the “Class A Shares”) at a price to the public of $21.00 per Class A Share. Pursuant to the Underwriting Agreement, the Partnership also granted the Underwriters an option for a period of 30 days (the “Option”) to purchase up to an additional 3,000,000 Class A Shares (the “Additional Shares”) on the same terms.

The material terms of the Offering are described in the prospectus, dated June 18, 2015 (the “Prospectus”), filed by the Partnership with the Securities and Exchange Commission (the “Commission”) on June 19, 2015 pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”). The Offering is registered with the Commission pursuant to a Registration Statement on Form S-1, as amended (File No. 333-202634), initially filed by the Partnership with the Commission on March 10, 2015.

The Underwriting Agreement contains customary representations, warranties and agreements of the 8point3 Parties, and customary conditions to closing, obligations of the parties and termination provisions. The 8point3 Parties have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Underwriters may be required to make because of any of those liabilities.

The Offering closed on June 24, 2015. The Partnership received proceeds (net of underwriting discounts and structuring fees but before offering expenses) from the Offering of approximately $393.8 million. As described in the Prospectus, the Partnership used all of the net proceeds of the Offering to purchase 20,000,000 common units representing limited liability company interests in 8point3 Operating Company, LLC (“OpCo”), representing approximately 28.2% of OpCo’s outstanding limited liability company interests after the Offering. OpCo used (i) approximately $154.4 million of such net proceeds to make a cash distribution to First Solar, Inc. (“First Solar”), (ii) approximately $201.6 million of such net proceeds to make a cash distribution to SunPower Corporation (“SunPower”) and (iii) approximately $37.8 million of such net proceeds for general purposes, including to fund future acquisition opportunities.

As more fully described in the Prospectus, the Underwriters and their respective affiliates are full service institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage services. The Underwriters and certain of their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for the Partnership and its affiliates, for which they received or may in the future receive customary fees and reimbursement of expenses.
