PEIX Alto Ingredients Inc

Pacific Ethanol, Inc. (Nasdaq:PEIX), the leading producer and marketer of low-carbon renewable fuels in the Western United States, announced that on April 8, 2014 it closed its previously announced underwritten public offering of 1,750,000 shares of its common stock at a public offering price of $16.00 per share, for gross offering proceeds of $28.0 million.

The net offering proceeds to Pacific Ethanol are expected to be approximately $26.0 million after deducting underwriting discounts and commissions and other estimated offering expenses. The company intends to use the net proceeds from the offering to fully repay the approximately $0.5 million in outstanding principal and accrued and unpaid interest owed under the terms of its senior unsecured notes, and will use the remaining balance of the net proceeds from the offering for general corporate purposes, including strengthening its balance sheet.

Neil Koehler, the company's president and CEO, stated "The proceeds from this capital raise strengthen our balance sheet by eliminating our senior unsecured debt, reducing our interest expense and providing additional cash reserves to support profitable growth."

Lazard Capital Markets LLC and Cowen and Company, LLC acted as the joint book-running managers for the offering, and Craig-Hallum Capital Group LLC acted as the co-manager.

The shares of common stock were sold pursuant to effective registration statements on Form S-3, together with a prospectus supplement and accompanying base prospectus, previously filed with the Securities and Exchange Commission.
