SAN DIEGO, CA., August 9, 2011 – Verenium Corporation (Nasdaq: VRNM), a leading industrial biotechnology company focused on the development and commercialization of high-performance enzymes, today reported a summary of recent Company highlights and financial results for the second quarter and six months ended June 30, 2011.

“I am very pleased with the progress we’ve made in terms of product revenues and partnership negotiations in the first half of the year,” said James E. Levine, President and Chief Executive Officer at Verenium. “In the second quarter we saw significant growth and diversification of product revenues through our Grain and Oilseed Processing products. In addition, we entered into an important collaboration with Novus International Inc. to develop multiple products for the animal health and nutrition market, demonstrating the value of Verenium’s product development capabilities in the large and growing global industrial enzymes market.”

Since the beginning of 2011, Verenium has made significant progress on both operational and financial fronts. Recent accomplishments include:

Operational/Industry Performance:

Animal Health and Nutrition

Corporate/Financial:

Financial Results

In the commentary below, the historical results of the Company’s ligno-cellulosic biofuels business for current and prior periods have been reclassified into discontinued operations as a result of the sale of the ligno-cellulosic biofuels business on September 2, 2010 to BP Biofuels North America LLC.

Revenues

Revenues for the periods ended June 30, 2011 and 2010 were as follows (in thousands):

Total revenues for the six months ended June 30, 2011 increased 10% to $28.5 million from $25.9 million for the same period in the prior year, with product revenues representing approximately 96% of total revenues in both periods. Product revenues for the six months ended June 30, 2011 increased 11% to $27.5 million from $24.9 million for the same period in the prior year, primarily due to an increase in revenues from grain processing enzymes, including Fuelzyme^® alpha-amylase, Veretase^® alpha-amylase, Deltazym^® GA L-E5 glucoamylase and Xylathin^TM xylanase. These products continued to gain traction in the grain ethanol markets and together with Purifine^® PLC for soybean oil processing, achieved significant revenue growth over 2010.

Product Gross Profit and Gross Margin

Product gross profit for the six months ended June 30, 2011 increased 6% to $10.0 million from $9.5 million for the same period in prior year. Gross margin decreased to 36% of product revenue for the six months ended June 30, 2011, compared to 38% for the six months ended June 30, 2010. Gross margin decreased primarily due to a decrease in the royalty paid as profit share from sales of Phyzyme phytase by our partner Danisco Animal Nutrition.

Operating Expenses (excluding cost of product revenue and restructuring expense)

Excluding cost of product revenues and restructuring, total operating expenses related to continuing operations for the six months ended June 30, 2011 decreased to $14.1 million (including share-based compensation of $0.3 million) from $16.3 million (including share-based compensation of $0.6 million) for the same period in the prior year; this is primarily due to reimbursement of legal fees of $1.1 million for expenses incurred during 2010 for defense of the Company’s noteholder lawsuit which was settled on March 23, 2011, and to initiatives to decrease general and administrative expenses. As a partial offset, research and development costs for continued investment in pipeline products showed an increase.

Restructuring Expense

On March 31, 2011 the Company closed its office in Cambridge, Massachusetts, resulting in a charge of $2.9 million, consisting of employee termination costs, facilities closure costs, and employee relocation costs for several employees who were relocated to San Diego.

Operating Loss from Continuing Operations

Operating loss from continuing operations for the six months ended June 30, 2011 was $6.0 million compared to $5.7 million for the same period in 2010. This increase is primarily reflective of restructuring expenses of $2.9 million. Excluding the impact of restructuring, operating loss from continuing operations decreased $2.7 million, primarily due to the reimbursement of legal fees and further reductions in general and administrative expenses.

Net Income (loss) from Continuing Operations

Net income from continuing operations for the six months ended June 30, 2011 was $2.3 million compared to a net loss of $9.9 million for the same period in 2010, on a GAAP accounting basis. Adjusted for the impact of non-cash items related to the Company’s convertible debt, the Company’s non-GAAP pro-forma net loss from continuing operations for the six months ended June 30, 2011 was $7.7 million compared to $9.8 million for the same period in the prior year. The Company believes that excluding the impact of these items provides a more consistent measure of operating results.

Balance Sheet

The Company ended the second quarter of 2011 with $44.6 million in cash and cash equivalents, $5.0 million in restricted cash, and $44.2 million in debt at face value. Subsequent to the end of the second quarter, on July 27, 2011, the Company repurchased $8.2 million in principal amount of its outstanding convertible notes in a privately negotiated transaction. To effect this repurchase, the Company paid a total of $7.7 million in cash to a noteholder to retire principal, plus $0.2 million of accrued interest as of the closing date, leaving the Company with approximately $36 million in face value of debt at that date.

“We are encouraged by the strong operational and financial performance achieved in the first half of the year,” said Jeffrey Black, Senior Vice President and Chief Financial Officer. “Our ability to increase product revenues and product gross profit, while at the same time lowering operating expenses and conserving cash, signifies that we are executing on our strategy to strengthen our balance sheet and position the Company for future growth.”
