"We met our margin and bottom line financial goals in the first quarter by adjusting our downstream channels and operating expenses," said Tom Werner, SunPower president and CEO. "Our revenue was lower than plan as a result of changing market conditions in Europe. Operationally, we exceeded our manufacturing cost reduction targets for the quarter and remain on plan to achieve our efficiency adjusted panel cost per watt target of $1.08 in the fourth quarter of this year. Execution on the Fab 3 ramp continues to surpass our internal forecasts as yields and equipment efficiency again reached record levels.

"We were also pleased to recently announce Total's transformational investment in SunPower through a share tender offer which began on May 3, 2011," continued Werner. "With Total's $1 billion credit support agreement, solar research and development investments and other resources available through its global network, we will be taking the next step in positioning our business for accelerated growth and long-term success. Our relationship with Total will improve our capital structure enabling SunPower to accelerate our power plant and commercial development businesses, and expand our manufacturing capacity with lower cash requirements."

Other key milestones achieved by the company since the fourth quarter of 2010 include:


    --  $1.2 billion U.S. Department of Energy loan guarantee conditional
        commitment and final county permit approval awarded for 250 megawatt
        (MW) California Valley Solar Ranch
    --  19-MW Alamosa power plant for Xcel Energy completed - largest solar
        power plant in Colo.
    --  11-MW rooftop contract awarded by Tucson Electric Power
    --  48-MW supply agreement signed with Toshiba
    --  75-MW per year Silicon Valley solar panel manufacturing facility
        dedicated with California Governor Brown and U.S. Energy Secretary Chu
    --  Surpassed 1,600 partners in global dealer network in Q1 2011

"Revenues and inventory levels in the first quarter were impacted by the pause in business activity in Italy, as several projects awaited clarity on the new tariffs," said Dennis Arriola, SunPower CFO. "Italy's new feed-in-tariff, announced earlier this month, follows the trend across Europe of favoring rooftop solar investment. SunPower's high efficiency systems and flexible dealer/partner network positions us effectively to respond to the uncapped rooftop market in Italy and other countries. As a result, we are in the process of optimizing our portfolio allocation geographically and across our downstream channels for the remainder of 2011. We expect to complete this process in the near future and plan to revise our 2011 guidance before the end of the second quarter to reflect the recent changes in Italy."

For the second quarter of 2011, the company expects revenue to be in the range of $500 to $550 million and MW recognized to be in the 160 to 190 MW range. For fiscal year 2011, the company expects MW recognized to be consistent with previous guidance of 825 to 920 MW.

Segment Reporting Information

The UPP Segment refers to both our large-scale solar products and systems business including power plant project development and project sales, turn-key power plant EPC and O&M services, as well as components sales which includes large volume sales of solar panels and mounting systems to third parties. The R&C Segment refers to our solar equipment sales into the residential and small commercial market through our third-party global dealer network, as well as direct sales and EPC and O&M services installing rooftop and ground-mounted solar systems for the new homes, commercial and public sectors.

Non-GAAP Measures

To supplement the consolidated financial results prepared under GAAP, SunPower uses non-GAAP measures which are adjusted from the most directly comparable GAAP results to exclude non-cash charges related to amortization of intangible assets and promissory notes, stock-based compensation and interest expense as well as exclude non-cash net gains (losses) on mark-to-market and foreign currency derivative instruments, share lending arrangement and changes in our equity investment in joint ventures, and the related tax effects of these adjustments. Management does not consider these non-cash items in evaluating the core operational activities of SunPower. Management uses these non-GAAP measures internally to make strategic decisions, forecast future results and evaluate SunPower's current performance. Most analysts covering SunPower use the non-GAAP measures as well. Given management's use of these non-GAAP measures, SunPower believes these measures are important to investors in understanding SunPower's current and future operating results as seen through the eyes of management. In addition, management believes these non-GAAP measures are useful to investors in enabling them to better assess changes in SunPower's core business across different time periods. These non-GAAP measures are not in accordance with or an alternative for GAAP financial data and may be different from non-GAAP measures used by other companies.

Fiscal Periods

SunPower reports on a fiscal-year basis and ends its quarters on the Sunday closest to the end of the applicable calendar quarter, except in a 53-week fiscal year, in which case the additional week falls into the fourth quarter of that fiscal year.

About SunPower's Non-GAAP Financial Measures

To supplement its consolidated financial results presented in accordance with GAAP, SunPower uses non-GAAP measures which are adjusted from the most directly comparable GAAP results to exclude non-cash charges related to amortization of intangible assets and promissory notes, stock-based compensation and interest expense as well as exclude non-cash net gains (losses) on mark-to-market and foreign currency derivative instruments, share lending arrangement and changes in our equity investment in joint ventures, and the related tax effects of these adjustments. The specific non-GAAP measures listed below are gross margin, operating income and net income per share. Management believes that each of these non-GAAP measures (gross margin, operating income and net income per share) are useful to investors by enabling them to better assess changes in each of these key elements of SunPower's results of operations across different reporting periods on a consistent basis, independent of these non-cash items. Thus, each of these non-GAAP financial measures provides investors with another method for assessing SunPower's operating results in a manner that is focused on its ongoing core operating performance, absent the effects of amortization of intangible assets and promissory notes, stock-based compensation, interest expense, net gains (losses) on mark-to-market and foreign currency derivative instruments, share lending arrangement and changes in our equity investment in joint ventures. Management also uses these non-GAAP measures internally to assess the business and financial performance of current and historical results, for strategic decision making, forecasting future results and evaluating the company's current performance. Many of the analysts covering SunPower also use these non-GAAP measures in their analyses. These non-GAAP measures are not in accordance with or an alternative for GAAP financial data, the non-GAAP results should be reviewed together with the GAAP results and are not intended to serve as a substitute for results under GAAP, and may be different from non-GAAP measures used by other companies.

o Non-GAAP gross margin. The use of this non-GAAP financial measure allows management to evaluate the gross margin of SunPower's core businesses and trends across different reporting periods on a consistent basis, independent of non-cash charges including amortization of intangible assets, stock-based compensation and interest expense. This non-GAAP financial measure is an important component of management's internal performance measurement process as it is used to assess the current and historical financial results of the business, for strategic decision making, preparing budgets and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to evaluate SunPower's revenue generation performance relative to the direct costs of revenue of its core businesses.

o Non-GAAP operating income. The use of this non-GAAP financial measure allows management to evaluate the operating results of SunPower's core businesses and trends across different reporting periods on a consistent basis, independent of non-cash charges including amortization of intangible assets and promissory notes, stock-based compensation and interest expense. Non-GAAP operating income is an important component of management's internal performance measurement process as it is used to assess the current and historical financial results of the business, for strategic decision making, preparing budgets and forecasting future results. Management presents this non-GAAP financial measure to enable investors and analysts to understand the results of operations of SunPower's core businesses and to compare results of operations on a more consistent basis against that of other companies in the industry.

o Non-GAAP net income per share. Management presents this non-GAAP financial measure to enable investors and analysts to assess SunPower's operating results and trends across different reporting periods on a consistent basis, independent of non-cash items including amortization of intangible assets and promissory notes, stock-based compensation, interest expense, net gains (losses) on mark-to-market and foreign currency derivative instruments, share lending arrangement and changes in our equity investment in joint ventures, and the tax effects of these non-GAAP adjustments. In addition, investors and analysts can compare SunPower's operating results on a more consistent basis against that of other companies in the industry. It should be noted that diluted weighted-average shares are determined on a GAAP basis and the resulting share count is used for computing both GAAP and Non-GAAP diluted net income per share.

Non-Cash Items

o Amortization of intangible assets. SunPower incurs amortization of intangible assets as a result of acquisitions, which includes in-process research and development, patents, project assets, purchased technology and trade names. SunPower excludes these items because these expenses are not reflective of ongoing operating results in the period incurred. These amounts arise from prior acquisitions and have no direct correlation to the operation of SunPower's core businesses.

o Stock-based compensation. Stock-based compensation relates primarily to SunPower stock awards such as stock options and restricted stock. Stock-based compensation is a non-cash expense that varies in amount from period to period and is dependent on market forces that are difficult to predict. As a result of this unpredictability, management excludes this item from its internal operating forecasts and models. Management believes that non-GAAP measures adjusted for stock-based compensation provide investors with a basis to measure the company's core performance against the performance of other companies without the variability created by stock-based compensation.

o Amortization of promissory notes. Included in the total consideration for a prior acquisition completed on March 26, 2010 is $14 million in promissory notes to the acquiree's management shareholders issued by SunPower. Since the vesting and payment of the promissory notes are contingent on future employment, the promissory notes are considered deferred compensation and therefore are not included in the purchase price allocated to the net assets acquired. SunPower excludes this non-cash charge over the service period required under the terms of the promissory notes because these expenses are not reflective of ongoing operating results in the period incurred. These amounts arise from prior acquisitions and have no direct correlation to the operation of SunPower's core businesses.

o Non-cash interest expense. SunPower separately accounted for the liability and equity components of its convertible debt issued in 2007 in a manner that reflected interest expense equal to its non-convertible debt borrowing rate. In addition, SunPower measured the two share lending arrangements entered into in connection with its convertible debt issued in 2007 at fair value and amortized the imputed share lending costs in current and prior periods. As a result, SunPower incurs interest expense that is substantially higher than interest payable on its 1.25% senior convertible debentures and 0.75% senior convertible debentures.

In addition, SunPower separately accounted for the fair value liabilities of the embedded cash conversion option and the over-allotment option on its 4.5% senior cash convertible debentures issued in 2010 as an original issue discount and a corresponding derivative conversion liability. As a result, SunPower incurs interest expense that is substantially higher than interest payable on its 4.5% senior cash convertible debentures. SunPower excludes non-cash interest expense because the expense is not reflective of its ongoing financial results in the period incurred. Excluding this data provides investors with a basis to compare the company's performance against the performance of other companies without non-cash interest expense.

o Loss on change in equity interest in unconsolidated investee. On October 20, 2010, First Philec Solar Corporation issued 0.5 million new shares of common and preferred stock to current investors. SunPower participated in the share issuance but did not receive a proportionate number of shares to maintain its previously reported equity interest. As a result of the new stock issuance by First Philec, SunPower's percentage equity interest in First Philec decreased from 20.1% to 14.5% of First Philec's issued and outstanding shares of common and preferred stock. SunPower recognized a non-cash loss of $0.3 million representing the excess of SunPower's per share carrying value of its shares over the average price of the additional shares issued in October 2010. SunPower excluded the $0.3 million loss in the fourth quarter of 2010 from its non-GAAP results because it was not realized in cash and it is not reflective of the company's ongoing financial results. Excluding this data provides investors with a basis to compare the company's performance against the performance of other companies without non-cash losses on changes in the company's equity interest in unconsolidated investees.

o Gain (loss) on mark-to-market derivative instruments. In connection with the issuance of its 4.5% senior cash convertible debentures in 2010, SunPower entered into certain convertible debenture hedge and warrant transactions with respect to its class A common stock intended to reduce the potential cash payments that would occur upon conversion of the debentures. The convertible debenture hedge and warrant transactions consisting of call option instruments are deemed to be mark-to-market derivatives until such transactions settle or expire. As of December 23, 2010, the warrant transactions were amended to be share-settled rather than cash-settled, therefore, the warrant transactions are not subject to mark-to-market accounting treatment subsequent to December 23, 2010. In addition, the embedded cash conversion option of the debt is deemed to be a mark-to-market derivative instrument during the period in which the cash convertible debt remains outstanding. Finally, the over-allotment option in favor of the debenture underwriters is deemed a mark-to-market derivative instrument during the period the over-allotment option remained unexercised, or from April 1, 2010 through April 5, 2010. SunPower excluded the net gain (loss) relating to the above mentioned derivative instruments from its non-GAAP results because it was not realized in cash and it is not reflective of the company's ongoing financial results. Excluding this data provides investors with a basis to compare the company's performance against the performance of other companies without a net non-cash gain (loss) on mark-to-market derivative instruments.

o Gain on share lending arrangement. SunPower loaned 2.9 million shares of its class A common stock to Lehman Brothers International (Europe) Limited ("LBIE") in 2007. In connection with the bankruptcy filing of LBIE on September 15, 2008 SunPower recorded a $213.4 million non-cash loss in the third quarter of 2008. In the fourth quarter of 2010, SunPower entered into an assignment agreement with Deutsche Bank AG - London Branch under which the company assigned to Deutsche Bank its claims against LBIE in connection with the share lending arrangement for cash proceeds of $24.0 million. SunPower had excluded the $213.4 million non-cash loss in the third quarter of 2008 from its non-GAAP results of operations. SunPower has also excluded the $24.0 million cash received from the sale of its claim against LBIE to Deutsche Bank. Excluding the data related to the share lending arrangement provides investors with a basis to compare the company's performance against the performance of other companies without such non-operational transactions.

o Loss on foreign currency derivatives. SunPower has an active hedging program designed to reduce its exposure to movements in foreign currency exchange rates. As a part of this program, SunPower designates certain derivative transactions as effective cash flow hedges of anticipated foreign currency revenues and records the effective portion of changes in the fair value of such transactions in accumulated other comprehensive income (loss) until the anticipated revenues have occurred, at which point the associated income or loss would be recognized in revenue. In the first quarter of fiscal 2011, in connection with the decline in forecasted revenue surrounding the change in Italian governmental incentives, SunPower reclassified an amount held in accumulated other comprehensive income (loss) to other income (expense), net for certain previously anticipated transactions which did not occur or were now probable not to occur, which totaled a loss of $4.6 million. SunPower excludes this item as it is not reflective of ongoing operating results and excluding this data provides investors with a basis to compare the company's performance against the performance of other companies without such transactions.

o Tax effect. This amount is used to present each of the amounts described above on an after-tax basis with the presentation of non-GAAP net income per share.
