NanoH2O, Inc. Secures Over $60 Million in Equity and Debt Financing: BASF Venture Capital, Total Energy Ventures and Keytone Ventures Co-Lead $40 Million Equity Funding to Accelerate the Company’s Commercial Operations and Manufacturing Capabilities

El Segundo, CA | Posted on April 30th, 2012

BASF Venture Capital GmbH, Total Energy Ventures International and Keytone Ventures co-led the $40 million equity financing that included all of NanoH2O's existing investors including Khosla Ventures, Oak Investment Partners, CalPERS Clean Energy & Technology Fund represented by Capital Dynamics and PCG Clean Energy & Technology Fund. The $20.5 million in growth capital, working capital and equipment financing credit facilities were provided by Comerica Bank and Lighthouse Capital Partners, with the working capital line backed by the Export-Import Bank of the United States. The $40 million investment brings NanoH2O's total equity funding to $75 million, and total debt and equity funding to over $100 million, making the Company one of the most highly funded water technology companies in the industry. Proceeds from the equity offering will enable the Company to accelerate its growth, expand its manufacturing capabilities and broaden its product offerings.

Jeff Green, Co-Founder and Chief Executive Officer of NanoH2O stated, "We are delighted to have such highly regarded, international organizations invest in our future and appreciate the continued support of our existing, globally renowned investors. With these funds and new strategic partners, we are well positioned to continue to provide our global customers with new, leading-edge RO membranes that lower the energy, operating and capital costs of desalination and other water treatment applications.

"There is a great demand worldwide for innovative technologies to produce drinking water from seawater," said Dirk Nachtigal, Managing Director, BASF Venture Capital. "NanoH2O has developed special nanostructured polymer-based membranes for seawater desalination which are particularly effective in removing the salt from seawater in a highly energy efficient way," explained Nachtigal.

Véronique Hervouet, Senior Vice President, Investments, Total Energy Ventures added, "The need for innovative technologies to meet the increasing demand for fresh water while lowering its energy and environmental footprint has never been greater. NanoH2O's ability to rapidly develop novel membranes for water treatment applications fits our mission to invest in companies with unique technologies that bring smart and sustainable solutions to the energy industry."

In addition, Joe Zhou, Managing Partner of Keytone Ventures, stated "China is undergoing immense economic and industrial growth. As infrastructure expands, water supply challenges are driving the need for new alternatives in treatment technologies. Keytone is committed to supporting cleantech innovation and furthering advanced solutions in the water sector. China is one of the largest desalination markets in the world and we are eager to partner with NanoH2O to meet the growing demand."

In connection with this financing, representatives from BASF Venture Capital, Total Energy Ventures and Keytone Ventures will join the Company's board of directors.
