Energy Conversion Devices Reports Second Quarter 2007 Operating Results

ROCHESTER HILLS, Mich., Feb. 8, 2007 -- Energy Conversion Devices, Inc. (ECD Ovonics) today reported its results for the second quarter ended December 31, 2006. The company reported a net loss of $2.9 million (or $0.07 per share) on revenues of $22.9 million in the second quarter of fiscal 2007, as compared to a net loss of $5.7 million (or $0.19 per share) on revenues of $24.3 million in the second quarter of fiscal 2006. The company also reported a net loss of $5.2 million (or $0.13 per share) on revenues of $50.1 million for the six months ended December 31, 2006, as compared to a net loss of $12.2 million (or $0.42 per share) on revenues of $47.5 million for the six months ended December 31, 2005.

"We had a challenging quarter on a number of fronts, but we also marked important successes during the quarter," said Chairman and CEO Robert C. Stempel. "We successfully launched our new Auburn Hills 2 facility, effectively doubling our PV module manufacturing capacity once it is fully ramped up this fall, and our new Greenville facilities are well underway. In addition, our Cobasys and Ovonyx joint ventures are making significant progress with their respective product commercialization initiatives."

  The following are highlights from ECD Ovonics' second quarter of 2007:

  * ECD Ovonics' wholly owned subsidiary United Solar Ovonic had operating
    income of $1.2 million on revenues of $19.2 million in the second
    quarter of fiscal 2007, as compared to operating income of $1.8 million
    on revenues of $21.7 million in the second quarter of fiscal 2006.  Its
    operating income was $2.6 million on revenues of $43.1 million in 2007
    for the six months ended December 31, 2006, as compared to operating
    income of $3.4 million on revenues of $41.0 million in 2006 for the six
    months ended December 31, 2005.  The second quarter of fiscal 2007
    results include $750,000 of preproduction costs and a $1 million
    decrease in the allowance for uncollectible accounts for one of our
    major customers.

  * As expected, United Solar Ovonic's gross profit margin was impacted by
    costs in the second quarter of fiscal 2007 associated with production
    capacity ramp up at its new Auburn Hills 2 manufacturing facility,
    decreasing to 16.0% in the second quarter of fiscal 2007 from 21.2% in
    the second quarter of fiscal 2006 and was unchanged for the six-month
    period ended December 31, 2006, as compared to the prior year period.

  * United Solar Ovonic currently has 58MW of annual production capacity,
    which reflects 30MW added in December 2006, as the company placed in
    service the manufacturing equipment for its new Auburn Hills 2
    manufacturing facility.  The company is also constructing two 60MW per
    annum PV cell manufacturing facilities in Greenville, Michigan, which
    are expected to begin operation in late 2007 and mid-2008.  The
    company's expansion plan increases United Solar Ovonic's manufacturing
    capacity to 118MW, 178MW and over 300MW per annum by the end of calendar
    years 2007, 2008 and 2010, respectively.

  * United Solar Ovonic's largest customer, Solar Integrated Technologies,
    Inc. ("SIT"), recently announced a 2MW roofing system using United Solar
    Ovonic's PV modules to be installed at Tesco USA's distribution center
    under construction in Riverside, California.  SIT recently completed an
    equity offering and used a portion of the proceeds to pay its
    outstanding payables to the company.  SIT, which had not purchased any
    products from United Solar Ovonic during the current fiscal year, has
    resumed purchasing United Solar Ovonic's PV modules and will begin
    receiving shipments in the third quarter.

  * United Solar Ovonic's solar modules have been installed and activated in
    a 433KW array by SunEdison, LLC on a Staples Distribution Center in
    Killingly, Conn.  This installation, which represents the largest solar
    panel installation in New England, will provide a significant portion of
    the building's electricity and reduce overall electricity costs.  As is
    becoming an increasingly common structure for commercial customers,
    Staples will purchase electricity from the array under a long-term power
    purchase agreement without the up-front capital costs, which are being
    funded by a third-party source that owns the array.

  * United Solar Ovonic recently announced a joint venture in China to
    assemble PV modules from solar cells supplied by United Solar Ovonic
    beginning in late 2007.  This joint venture, owned 75% by United Solar
    Ovonic, is expected to open new sales opportunities for United Solar
    Ovonic in the China solar markets, as well as provide manufacturing cost
    advantages for modules shipped globally.  It is subject to, among other
    things, government approvals.

  * United Solar Ovonic added a solar industry veteran to its sales and
    marketing group.  Karl-Heinz Toenges joined the company as its Vice
    President of Sales and Marketing in Europe.  Mr. Toenges is a seasoned
    industry executive with broad operational experience and extensive
    industry connections, who will enhance the company's global sales and
    marketing activities.

  * Cobasys, the only United States-based supplier of NiMH battery systems
    for hybrid electric vehicles, continued to successfully compete for new
    business opportunities, including selection by General Motors to provide
    Cobasys' NiMHax(R) Nickel Metal Hydride (NiMH) battery system for GM's
    2007 Saturn Aura Green Line Hybrid Mid-Size Sedan, which is expected to
    be available to consumers in the spring of 2007.

  * Cobasys was awarded a contract to develop and test lithium-ion battery
    system technology for the General Motors plug-in hybrid electric vehicle
    program, recognizing Cobasys' proven expertise in providing complete
    "plug-and-play" energy storage system solutions for today's hybrid
    electric vehicles.  Cobasys will be working with its partner,
    A123Systems, to provide complete battery systems featuring A123Systems'
    proprietary nanophosphate technology.

  * ECD Ovonics' Ovonyx, Inc. joint venture secured a new license with
    Qimonda AG to commercialize Ovonic Unified Memory (OUM) technology.
    Additionally, a joint research program consisting of Qimonda, IBM and
    Macronix announced positive research results for a prototype phase-
    change memory device that they had designed, built and demonstrated.

  * Ovonyx also added an industry veteran to its management team, announcing
    that Dr. Stefan Lai joined the company as Vice President of Business
    Development.  Dr. Lai, the co-inventor of the industry-standard ETOX
    flash memory cell, was previously Vice President of the Flash Memory
    Group and CTO & Co-Director of California Manufacturing and Technology
    at Intel Corporation.

  * Mr. Pasquale Pistorio resigned as a director of the Company effective
    February 6, 2007, due to other professional and personal commitments.
    The Company has no immediate plans to appoint a replacement.

  * The quarter-over-quarter results were favorably impacted by higher
    interest income, together with approximately $0.8 million of favorable
    one-time items in 2006.

Mr. Stempel added, "While we are not in the practice of providing guidance, I want to update an operating goal that we had established regarding sustainable profitability. We are on track with a number of our businesses, including our United Solar Ovonic business, but we do not at this time expect to achieve sustainable profitability by the end of this fiscal year as previously projected. This is in large part due to the fact that it is taking longer than we originally expected to secure additional funding opportunities for our emerging technologies. We remain firmly committed to sustainable profitability and will be pursuing funding and restructuring alternatives to achieve our goal in the near term."

"The markets in which we participate are experiencing robust growth, and we are positioned to capitalize on the opportunities and succeed in these markets. The solar market continues its rapid, global expansion, buoyed in part by incentives, but also by improved economics. Our United Solar Ovonic subsidiary, a global leader for thin-film solar modules, is acting globally through its aggressive expansion manufacturing plans and marketing activities," Stempel said. "Our Cobasys joint venture is becoming a key Tier 1 supplier in the auto industry at the same time this industry is making a broad commitment to electric vehicles, which was demonstrated at the recent Detroit and Los Angeles Auto Shows. And, our Ovonyx joint venture continues to add important licensees who are successfully demonstrating products based on OUM technology for a growing global market of memory-intensive applications. Our products are addressing important needs in each of these markets and we are confident of our capabilities to pursue these opportunities."

Additional information about the company and its consolidated financial results can be found in the company's Quarterly Report on Form 10-Q for the quarter ended December 31, 2006, which was filed with the Securities and Exchange Commission today and will be available on the company's website.
