Green Plains Completes Placement of 3.25% Convertible Senior Notes Due 2018

Raises $120 Million After Initial Purchasers Exercised Over-Allotment Option

OMAHA, NEB. (GLOBE NEWSWIRE) – September 20, 2013 – Green Plains Renewable Energy, Inc. (NASDAQ: GPRE) (the “Company”) announced today the completion of its private placement of $120 million aggregate principal amount of 3.25% Convertible Senior Notes due 2018 (the “notes”). This includes the purchase of $20 million aggregate principal amount of notes by the initial purchasers pursuant to the exercise of their overallotment option. The notes were offered and sold to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, by the initial purchasers of the notes.

The notes will mature on October 1, 2018 and will bear interest at a fixed rate of 3.25% per year, payable on April 1 and October 1 of each year, beginning April 1, 2014. The notes will be general senior, unsecured obligations of the Company. On and after October 1, 2016, and prior to the maturity date, the Company may redeem all, but not less than all, of the notes for cash if the sale price of the Company’s common stock equals or exceeds 140% of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the Company delivers notice of the redemption. The redemption price will equal 100% of the principal amount of the notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a fundamental change, holders of the notes will have the right, at their option, to require the Company to repurchase their notes in cash at a price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The notes will be convertible, at the option of the holders, into consideration consisting of, at the Company’s election, cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock (and cash in lieu of fractional shares) until the close of business on the scheduled trading day immediately preceding the maturing date. However, before April 1, 2018, the notes will not be convertible unless certain conditions are satisfied. The initial conversion rate is 47.9627 shares of the Company’s common stock per $1,000 principal amount of notes, which is equivalent to an initial conversion price of approximately $20.85 per share of the Company’s common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events. In addition, the Company may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including the Company’s calling the notes for redemption.

The net proceeds to the Company from this private placement is approximately $115.3 million, after deducting initial purchasers’ discounts and commissions and estimated offering expenses payable by the Company. The Company intends to use the net proceeds of this offering for general corporate purposes. While the Company does not have any binding commitments or definitive agreements to enter into potential acquisitions, it may use a portion of the net proceeds to acquire or invest in additional facilities, assets or technologies that it believes further its growth strategy. In addition, the Company may use a portion of the net proceeds to repurchase some of its outstanding 5.75% Convertible Senior Notes due 2015 through open market repurchases, privately negotiated transactions or otherwise.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the notes or any common stock issuable upon conversion of the notes, in any state or jurisdiction in which such offer, solicitation or sale would be unlawful. Any offers of the notes will be made only by means of a private offering memorandum. The notes and any shares of the Company’s common stock issuable upon conversion of the notes have not been registered under the Securities Act or applicable state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws.
