 Altair Nanotechnologies Reports Second Quarter 2013 Financial Results

Reno, NV (Marketwire – August 8, 2013) – Altair Nanotechnologies, Inc. (“Altair”) (NASDAQ: ALTI), today reported financial results for the second quarter ended June 30, 2013.

Altair reported revenues of $3.2 million for the second quarter compared to $0.5 million for the same period in 2012.  The gross loss was $0.1 million, due to inventory cost adjustments and the launching of new electric grid products, compared to $0.6 million for the same period in 2012.

Operating expenses were $3.0 million for the second quarter, a $1.4 million decrease from $4.4 million for the same period in 2012.  Planned reductions were achieved and accounted for the decrease of $1.4 million in the research and development and sales and marketing departments. General and administrative costs increased due to the ramp up of our China operations.

The net loss for the second quarter of 2013 was $3.0 million ($0.26 per share) compared to a net loss of $4.9 million ($0.42 per share) for the same period in 2012.

“Sixteen months ago, we put into action our plan to position the company for growth, reduce costs, and drive revenue opportunities,” stated Alexander Lee, Altair’s Chief Executive Officer. “We focused heavily on the execution of our deliverables to achieve these goals. Today, our teams in the U.S. and China act as one, and we are nearing the completion of our new nano lithium titanate and energy storage system plants on 106 acres that we acquired the land use rights for in Wu’an, China.

“In addition, we have delivered multiple grid-scale systems to leading grid operators that have stated how impressed they are with our product’s performance and that we can use as key references. We have reduced our operating expenses by 36% as compared to the quarter immediately preceding my start date back in April 2012, and we hit this target while ramping up our China team from just a few employees to a 78 person team. With respect to revenue, we recognized $3.2 million in revenue this quarter, which brings our mid-year revenue total to $5.0 million. We currently have $5.5 million in deferred revenue, and we are on track to have one of our best years on record. As we noted last quarter, 2013 will truly be a milestone year for Altair.”

Highlights for the quarter ended June 30, 2013 and subsequent events include:

● In June 2013, we entered into a memorandum of understanding with Tauron Dystrybucja SA. to jointly determine the necessary infrastructure needs for stationary energy storage systems based on nano lithium titanate batteries, and for the construction of power and frequency stabilization systems in Poland. TAURON is a subsidiary of TAURON Polska Energia S.A., Poland's second largest energy company.

● In May 2013, Northern Altair acquired a second conditional 50-year land use right with respect to approximately 40 acres of industrial land in Wu’an, China with an acquisition price of approximately $8.6 million which includes various land transfer taxes and fees that are equal to approximately $1.2 million. In turn, we expect to receive cash incentives as part of our economic development deal, which shall be equal to our acquisition price. The closing occurred on May 27, 2013. This Land will be used for the Company’s nano lithium titanate and energy storage system manufacturing operations in China.

● In May 2013, we decommissioned our nano lithium titanate manufacturing equipment in Reno and shipped it to Northern Altair. This equipment is currently being installed in our new nano lithium titanate manufacturing facility in Wu’an, China.

● In April 2013, Altair completed a contract with Hawaiian Electric Light Company (“HELCO”) and Hawaii Natural Energy Institute (“HNEI”) for a 1.0 megawatt ALTI-ESS system. The system was commissioned at the Hawi Wind Farm on Hawaii’s Big Island in March 2013.

● In April 2013, Northern Altair transferred $1.5 million to Altair as a pre-payment for the transfer of Altair’s nano lithium titanate materials and equipment to Northern Altair. Northern Altair transferred $0.9 million to Altair as a pre-payment in March 2013, and they expect to transfer the balance due of $0.2 million in August 2013.

● In April 2013, Northern Altair received $1.9 million in cash incentives from the City of Wu’an, China. The total cash incentives received to date from Wu’an under our economic development deal is $13.7 million.

● Altair continues to have discussions with large transportation and industrial customers in the U.S, Europe and Asia, who are interested in using our battery systems in a variety of applications where the high-power attributes of our battery are a key consideration. Several customers are now testing our application kits, modules and Power Rack systems for various commercial applications.

Altair’s cash and cash equivalents decreased by $3.7 million, from $12.4 million at December 31, 2012 to $8.7 million at June 30, 2013. The net decrease of $3.7 million resulted from the net decrease in operating activities of $4.2 million, the net decrease in investing activities of $1.6 million and the net increase in financing activities of $2.4 million. The investing activities included the acquisition of the second land use right from the Government of Wu’an, China, which was paid for by using restricted cash, and the purchase of fixed assets by Northern Altair. The financing activity included the increase of deferred income due to receiving $1.9 million in cash incentives from the purchase of the first land use right.

Revenues increased by $2.7 million, from approximately $0.5 million during the quarter ended June 30, 2012 to approximately $3.2 million during the quarter ended June 30, 2013, primarily a result of revenue recognized for the sale of one ALTI-ESS system sold to HELCO and HNEI for their Hawi Wind farm on the Big Island of Hawaii.

“We continue to focus on improving our overall financial performance and have implemented additional cost reduction measures this past quarter that should further reduce our monthly operating expenses by approximately $200,000 when fully implemented,” stated Mr. Lee. “Our overall cash position, including restricted and long-term restricted classifications, currently stands at $17.8 million and we expect to receive $8.6 million in cash incentives from the Government of Wu’an in the second half of 2013.

“We have made significant progress in China marked by the nearing completion of construction of our manufacturing facilities. Our business development efforts in China are gaining traction, and we expect to launch several new projects there over the course of the next year. We are also encouraged by the many significant opportunities we have identified and are pursuing in Europe and the Americas. Our top-line revenue performance continues to gain momentum and we expect to post strong results in the second half of the year,” concluded Mr. Lee.
