Management to Host Conference Call Today at 10 a.m. ET

DEVENS, Mass., Aug. 7, 2013 (GLOBE NEWSWIRE) -- AMSC (Nasdaq:AMSC), a global solutions provider serving wind and power grid industry leaders, today reported financial results for its first quarter ended June 30, 2013.

Revenues for the first quarter of fiscal 2013 were $23.1 million, compared with $28.7 million for the same period of fiscal 2012 and $20.4 million for the fourth quarter of fiscal 2012. The 13% improvement from the fourth quarter of fiscal 2012 was driven by higher revenues from the Company's Wind segment.

AMSC's net loss for the first quarter of fiscal 2013 was $10.5 million, or $0.18 per share, compared with $10.3 million, or $0.20 per share, for the same period of fiscal 2012 and $19.8 million, or $0.35 per share, for the fourth quarter of fiscal 2012.

The Company's non-GAAP net loss for the first quarter of fiscal 2013 was $8.1 million, or $0.14 per share, compared with a non-GAAP net loss of $11.0 million, or $0.21 per share, for the first quarter of fiscal 2012 and $11.8 million, or $0.21 per share, for the fourth quarter of fiscal 2012. Please refer to the financial table below for a reconciliation of GAAP to non-GAAP results.

Cash, cash equivalents, and restricted cash at June 30, 2013 totaled $39.5 million, compared with $50.2 million as of March 31, 2013.

For the second fiscal quarter ending September 30, 2013, AMSC expects that its revenues will exceed $23 million and that its net loss will be less than $17 million, or $0.28 per share. This forecast excludes any impact from mark-to-market adjustments related to the Company's derivative liability and warrants. AMSC expects that its non-GAAP net loss for its second quarter of fiscal 2013 will be less than $12 million, or $0.20 per share. The Company's net loss and non-GAAP net loss are expected to be impacted by a less favorable mix of revenues in the second quarter compared with the first quarter of fiscal 2013. AMSC expects to have more than $30 million in cash, cash equivalents and restricted cash on September 30, 2013.

"AMSC continued to execute to plan for the first fiscal quarter, growing revenues by 13% and reducing net loss by 47% on a sequential basis from the fourth quarter of fiscal 2012," said Daniel P. McGahn, AMSC President and CEO. "In fiscal 2013, we remain focused on effectively managing our cash position, while driving profitable revenue growth. We are reaffirming our guidance that we expect annual revenue growth of at least 25% in fiscal 2013 over fiscal 2012. We have a solid presence in several established markets and continue to seek opportunities to enter emerging markets where we see significant opportunity."

This press release contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Any statements in this release about future expectations, plans and prospects for the Company, including without limitation our expectations regarding our future financial results and cash balance, annual revenue growth, and our ability to penetrate emerging markets,and other statements containing the words "believes," "anticipates," "plans," "expects," "will" and similar expressions, constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements represent management's current expectations and are inherently uncertain.

There are a number of important factors that could materially impact the value of our common stock or cause actual results to differ materially from those indicated by such forward-looking statements. Such factors include: We have experienced recurring operating losses and recurring negative cash flows from operations which raise substantial doubt about our ability to continue as a going concern. This substantial doubt has resulted in a qualified opinion from our auditors with an explanatory paragraph regarding our ability to continue as a going concern. We believe this opinion may have an adverse effect on our customer and supplier relationships; our success in addressing the wind energy market is dependent on the manufacturers that license our designs; we may not realize all of the sales expected from our backlog of orders and contracts; our business and operations would be adversely impacted in the event of a failure or security breach of our information technology infrastructure; our success is dependent upon attracting and retaining qualified personnel and our inability to do so could significantly damage our business and prospects; we rely upon third-party suppliers for the components and subassemblies of many of our Wind and Grid products, making us vulnerable to supply shortages and price fluctuations, which could harm our business; many of our revenue opportunities are dependent upon subcontractors and other business collaborators; if we fail to implement our business strategy successfully, our financial performance could be harmed; problems with product quality or product performance may cause us to incur warranty expenses and may damage our market reputation and prevent us from achieving increased sales and market share; our contracts with the U. S. government are subject to audit, modification or termination by the U. S. government and include certain other provisions in favor of the government; the continued funding of such contracts remains subject to annual congressional appropriation which, if not approved, could reduce our revenue and lower or eliminate our profit; we may acquire additional complementary businesses or technologies, which may require us to incur substantial costs for which we may never realize the anticipated benefits; many of our customers outside of the United States are, either directly or indirectly, related to governmental entities, and we could be adversely affected by violations of the United States Foreign Corrupt Practices Act and similar worldwide anti-bribery laws outside the United States; we have limited experience in marketing and selling our superconductor products and system-level solutions, and our failure to effectively market and sell our products and solutions could lower our revenue and cash flow; we have experienced recurring losses from operations and negative operating cash flow; these factors raise substantial doubt regarding our ability to continue as a going concern; we have a history of operating losses, and we may incur additional losses in the future; our operating results may fluctuate significantly from quarter to quarter and may fall below expectations in any particular fiscal quarter; we may require additional funding in the future and may be unable to raise capital when needed; our debt obligations include certain covenants and other events of default;. Should we not comply with the covenants or incur an event of default, we may be required to repay our debt obligations in cash, which could have an adverse effect on our liquidity; if we fail to maintain proper and effective internal controls over financial reporting, our ability to produce accurate and timely financial statements could be impaired and may lead investors and other users to lose confidence in our financial data; we may be required to issue performance bonds or provide letters of credit, which restricts our ability to access any cash used as collateral for the bonds or letters of credit; changes in exchange rates could adversely affect our results from operations; growth of the wind energy market depends largely on the availability and size of government subsidies and economic incentives; we depend on sales to customers in China, and global conditions could negatively affect our operating results or limit our ability to expand our operations outside of China; changes in China's political, social, regulatory and economic environment may affect our financial performance; our products face intense competition, which could limit our ability to acquire or retain customers; our international operations are subject to risks that we do not face in the United States, which could have an adverse effect on our operating results; adverse changes in domestic and global economic conditions could adversely affect our operating results; we may be unable to adequately prevent disclosure of trade secrets and other proprietary information; our patents may not provide meaningful protection for our technology, which could result in us losing some or all of our market position; the commercial uses of superconductor products are limited today, and a widespread commercial market for our products may not develop; there are a number of technological challenges that must be successfully addressed before our superconductor products can gain widespread commercial acceptance, and our inability to address such technological challenges could adversely affect our ability to acquire customers for our products; we have not manufactured our Amperium wire in commercial quantities, and a failure to manufacture our Amperium wire in commercial quantities at acceptable cost and quality levels would substantially limit our future revenue and profit potential; third parties have or may acquire patents that cover the materials, processes and technologies we use or may use in the future to manufacture our Amperium products, and our success depends on our ability to license such patents or other proprietary rights; our technology and products could infringe intellectual property rights of others, which may require costly litigation and, if we are not successful, could cause us to pay substantial damages and disrupt our business; we have filed a demand for arbitration and other lawsuits against our former largest customer, Sinovel, regarding amounts we contend are overdue. We cannot be certain as to the outcome of these proceedings; we have been named as a party to purported stockholder class actions and stockholder derivative complaints, and we may be named in additional litigation, all of which will require significant management time and attention, result in significant legal expenses and may result in an unfavorable outcome, which could have a material adverse effect on our business, operating results and financial condition; our 7% convertible note contains warrants and provisions that could limit our ability to repay the note in shares of common stock and should the note be repaid in stock, shareholders could experience significant dilution; our common stock has experienced, and may continue to experience, significant market price and volume fluctuations, which may prevent our stockholders from selling our common stock at a profit and could lead to costly litigation against us that could divert our management's attention; and new regulations related to conflict-free minerals may force us to incur significant additional expenses. These and the important factors discussed under the caption "Risk Factors" in Part 1. Item 1A of our Form 10-K for the fiscal year ended March 31, 2013, and our other reports filed with the SEC, among others, could cause actual results to differ materially from those indicated by forward-looking statements made herein and presented elsewhere by management from time to time. Any such forward-looking statements represent management's estimates as of the date of this press release. While we may elect to update such forward-looking statements at some point in the future, we disclaim any obligation to do so, even if subsequent events cause our views to change. These forward-looking statements should not be relied upon as representing our views as of any date subsequent to the date of this press release.

Note: Non-GAAP net loss is defined by the company as net loss before adverse purchase commitments (recoveries) losses, net; stock-based compensation; amortization of acquisition-related intangibles; restructuring and impairment charges; Sinovel litigation costs; consumption of zero cost-basis inventory; non-cash interest expense; change in fair value of derivatives and warrants and other unusual charges; net of any tax effects related to these items. The company believes non-GAAP net loss assists management and investors in comparing the company's performance across reporting periods on a consistent basis by excluding these non-cash or other non-recurring charges that it does not believe are indicative of its core operating performance. The company also regards non-GAAP net loss as a useful measure of operating performance and cash flow to complement operating loss, net loss and other GAAP financial performance measures. In addition, the company uses non-GAAP net loss as a factor in evaluating management's performance when determining incentive compensation and to evaluate the effectiveness of its business strategies.

Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this release, however, should be considered in addition to, and not as a substitute for or superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. A reconciliation of non-GAAP to GAAP net loss is set forth in the table above.
