Fiscal year 2010 also saw a strengthening of OPT’s management team with several key appointments. Foremost among these, Charles F. Dunleavy was appointed OPT’s Chief Executive Officer, having served as the Company’s Senior Vice President and Chief Financial Officer since 2001, and as the Company’s Treasurer and Secretary and a member of the Board of Directors since 1990. From 1993 to 2001, he served as Vice President, Finance. During this time, Mr. Dunleavy had been key to OPT’s progress in expanding operations in Europe, North America, Australia and Japan, and the Company’s raising of over $140 million in equity capital in the US and Europe.

Other key appointments to the management team included Angus Norman as Chief Executive of Ocean Power Technologies Limited. Mr. Norman joined OPT from EDF Energy where he held the position of Managing Director of Sustainable Solutions and brings extensive leadership experience in the energy and renewable energy generation sector, as well as a nearly 30 year record of acquisition, divestment and project development in the energy, transport, minerals and infrastructure markets.

In June 2010, OPT announced the appointment of Michael G. Kelly as Vice President of Operations. Mr. Kelly joined OPT with 28 years of experience in the marine industry, spanning design, manufacturing, deployment and field service of large, complex ocean-based systems. The scope of this work has included the management of international commercial and technical teams to deliver best-in-class marine industry solutions within schedule and budget.

Also, in June 2010, OPT appointed Brian M. Posner to the position of Chief Financial Officer of the Company. Mr. Posner joined OPT with over 25 years of experience in both public and private companies, with a notable track record in working with capital markets, regulatory and accounting matters and strategic alliances. His career has encompassed NASDAQ-listed companies as well as early-stage and publicly-held businesses. In addition, Mr. Posner served on the audit staff of PriceWaterhouseCoopers, LLP where he had a diverse group of clients in the manufacturing, banking and natural resources sectors.

Charles F. Dunleavy, Chief Executive Officer of OPT, said: “This has been a pivotal year for OPT during which we made solid progress in advancing our existing projects as well as achieving major breakthroughs in our target markets worldwide. These were achieved against a background of a global credit crunch that has constrained the adoption of new technologies. However, OPT’s strong balance sheet, blue chip partnerships and progress in commercializing its technology have served it well during the year. With the important strengthening of our management team, we feel confident of our prospects for the year ahead and are excited about upcoming achievements that we expect to report on several fronts.”

Operational Review

The year ended April 30, 2010 represented another year of progress for OPT. The Company achieved key milestones in a number of ongoing projects and established strong foundations in new developments, which include:

HAWAII, US — OPT deployed an upgraded 40kW peak-rated PowerBuoy under its ongoing program with the US Navy for the development and construction of wave power systems at the Marine Corps Base in Oahu, Hawaii. The device has been in operation since its deployment in December 2009, and is producing power in accordance with expectations and testing protocols. In addition, the device has successfully survived significant storm conditions. The Company also received $380,000 in further funding for the commissioning and operation of this PowerBuoy system.

OREGON, US — Construction of the steel structure for the first PB150 PowerBuoy for a 1.5 MW commercial-scale project at Reedsport, Oregon was begun by Oregon Iron Works, a prominent local company, and is advancing as planned. With support from Pacific Northwest Generating Cooperative (PNGC Power) and funding from the US Department of Energy, OPT continued to work extensively with interested stakeholder groups at local, county, state and federal agency levels to develop this project, and progress was made in the overall permitting and licensing process. The project remains on schedule, with the PB150 construction expected to be completed by the end of 2010 and ocean testing expected to commence in 2011. This project is expected to be expanded subsequently in a second phase to a 10 PowerBuoy array connected to the west coast grid, after receipt of third party funding for the project.

During the year, OPT also signed a Memorandum of Understanding (“MOU”) with the State of Oregon to set forth an approach for developing wave power projects within the State’s coastal waters. This MOU outlines important principles for the potential development of future wave power facilities in Oregon. These principles are expected to be first applied to the development of OPT’s Coos Bay project in Oregon. The Company is studying the feasibility of building an OPT wave power station near Coos Bay, Oregon, in phases up to 100 MW. The project is in the initial stages of public and agency review.

SCOTLAND, UK — The construction of OPT’s first PB150 PowerBuoy has been completed, while the energy conversion and power take-off sub-assemblies are soon to be integrated into the buoy structure. OPT expects to conduct in-ocean trials off the coast of Scotland in the second half of calendar year 2010.

CORNWALL, UK — The South West of England Regional Development Agency (“SWRDA”) has placed a contract for the installation and commissioning of the infrastructure, including onshore electrical equipment, for its planned facility in Cornwall, England. Excavation at the site began in June 2010, and SWRDA expects that the final cabling and subsea infrastructure will be installed by the engineering contractor by the end of calendar year 2010. OPT has signed a commitment agreement with SWRDA to advance the development of one of the four wave power stations that are expected to comprise the Wave Hub — one of the world’s largest proposed renewable marine energy projects. OPT was the first company to sign the agreement, ratifying its long-standing involvement with this project.

SPAIN — Under a contract with Iberdrola S.A., the Company completed in-ocean trials of OPT’s Undersea Substation Pod (“USP”) product. The testing was successful and opens a new revenue opportunity for OPT. The USP was designed in-house by OPT for use in a utility-scale wave power station at a site approximately three miles off the coast of Santoña, Spain.

On March 3, 2010, OPT announced the receipt of an award of €2.2 million under the European Commission’s Seventh Framework Programme (FP7), by the European Commission’s Directorate responsible for new and renewable sources of energy, energy efficiency and innovation. The grant to OPT is part of a total award of €4.5 million to a consortium of companies, including OPT, to deliver a PowerBuoy wave energy device under a project entitled WavePort, with an innovative wave prediction capability and a “wave-by-wave” tuning system. Conditional on the receipt of significant additional funding, it is anticipated that this PowerBuoy will be deployed at the Santoña site in Spain.

US NAVY “LEAP” PROJECT — During the fiscal year 2010, OPT won a new $2.4 million contract from the US Navy to provide a wave energy conversion system for the Navy’s LEAP program. This contract, to be performed over a one-year period, is the initial award under a proposed four-year, $10-$15 million project to establish a prototype for a near-shore maritime surveillance for homeland security. Under the initial contract, OPT will provide its PowerBuoy wave energy conversion technology for testing with sensor-based communications systems, with the ultimate aim under the four-year program of developing a LEAP-based vessel detection system testbed. The preliminary design phase work has been submitted and is now under review. OPT expects to complete the initial $2.4 million contract in the second half of calendar year 2010.

US NAVY DEEP OCEAN APPLICATION — Progress continued on OPT’s ongoing project to provide the Company’s autonomous PowerBuoy technology for the US Navy’s Deep Water Active Detection System for ocean data gathering. The current $3.0 million contract was awarded in November 2008 following the completion of the initial test phase work by OPT. Deployment of the enhanced device is scheduled for the second half of calendar year 2010.

JAPAN — OPT signed an agreement in Japan for the development of the country’s first utility-scale wave power station with a consortium of three Japanese companies: Idemitsu Kosan Co., Mitsui Engineering & Shipbuilding Co. Ltd., and Japan Wind Development Co. Subject to the successful identification of a project site and completion of economic assessments, the parties plan to enter into an agreement to build a demonstration plant with up to three OPT PowerBuoys. The trial plant would provide the basis for the expected building of a commercial-scale OPT wave power station with an initial capacity of 10 MW or more — enough power for up to 3,000 households in Japan.

VICTORIA, AUSTRALIA — In November 2009, Ocean Power Technologies (Australasia) Pty Ltd (“OPTA”) was awarded, in partnership with Leighton Contractors Pty Ltd (“Leighton”), an A$66.46 million grant from the Federal Government of Australia towards building a 19 MW wave power project off the coast of Victoria, Australia. The award was one of four renewable energy projects approved by the Federal Government of Australia after considering over 30 applications, and is the only wave energy venture to receive a grant. The funding is intended to be used to advance the construction of a wave power station to be built in three phases to supply electricity to up to 10,000 homes. The project is to be developed by a special purpose company, Victorian Wave Partners Pty Ltd, that was formed by Leighton to collaborate with OPTA in pursuing wave power projects off the east and south coasts of Australia. The grant is conditional on the signing of a Funding Deed which will set out the terms of the grant, including funding milestones. Victoria Wave Partners is seeking the significant additional funding required to enable the completion of the 19 MW wave power station.

PB500 DEVELOPMENT PROGRAM — OPT’s technical achievements were recognized by the US Department of Energy in awarding the Company $1.5 million for the development of the next generation PowerBuoy wave power system. The DoE grant will be used to help fund the scale-up of the power output per device from the current level of 150kW to 500kW. In addition, the technology development effort will focus on increasing the power extraction efficiency and reliability, and will utilize an enhanced “Design-for-Manufacture” approach.

Financial Review

Revenues increased by $1.1 million in fiscal 2010, or 26%, to $5.1 million as compared to $4.0 million in fiscal 2009. This growth primarily reflects an increase in revenue from the US Navy under the Deep Water Active Detection System and LEAP programs, for which OPT provides its autonomous PowerBuoy technology. In addition, there was also an increase in revenue related to OPT’s project off the coast of Reedsport, Oregon. The growth in revenue generated by these projects was partially offset by the decline in revenue from OPT’s utility-scale project in Spain and the Company’s utility PowerBuoy project with US Navy at the Marine Corps Base in Hawaii, which is now in operation.

The Company’s contract order backlog at April 30, 2010 was $5.7 million, compared to $7.5 million at April 30, 2009. Most of this backlog is expected to be recognized as revenue during the fiscal year ending April 30, 2011.

The net loss attributable to OPT for the year ended April 30, 2010 was $19.2 million, compared to a net loss of $18.3 million in the prior year. The increase in the fiscal 2010 net loss was primarily attributable to costs incurred in the Company’s product development programs, which were $13.0 million for fiscal 2010 compared to $8.4 million for fiscal 2009 and a decrease in interest income due to a decrease in cash equivalents and marketable securities, as well as lower yields. The Company’s product development efforts were focused on increasing the output and reliability of the PowerBuoy technology. These factors were offset by an increase in gross profit, an increase in foreign exchange gains and a decrease in selling, general and administrative costs. Other income also increased in the year ended April 30, 2010 due to the favorable settlement of a claim against a supplier of engineering services during the first quarter of fiscal 2010.

The Company finished the year with a strong balance sheet. On April 30, 2010, total cash, cash equivalents, restricted cash and marketable securities were $66.8 million, compared to $82.7 million on April 30, 2009. Total “cash burn” for fiscal 2010 was $15.9 million, compared to $19.5 million for fiscal 2009. The Company’s cash equivalents and investments are highly liquid investments consisting primarily of term deposits with large commercial banks and U.S. Treasury notes.
