Zhone Technologies, Inc. (NASDAQ:ZHNE), a global leader in access network solutions, today reported its financial results for the second quarter ended June 30, 2009.

Revenue for the second quarter of 2009 was $30.3 million compared with $24.1 million for the first quarter of 2009 and $40.1 million for the second quarter of 2008. Net loss for the second quarter of 2009, calculated in accordance with generally accepted accounting principles (“GAAP”), was $2.3 million or $0.02 per share compared with a net loss of $6.9 million or $0.05 per share for the first quarter of 2009, and a net loss of $80.3 million or $0.53 per share for the second quarter of 2008. Pro forma earnings before stock-based compensation, interest, taxes, depreciation, lease liability accrual, gain on sale of intangible assets and goodwill impairment (“EBITDA”) was a $0.9 million loss for the second quarter of 2009, compared to a pro forma EBITDA loss of $5.5 million for the first quarter of 2009, and pro forma EBITDA loss of $5.2 million for the second quarter of 2008.

“Strong sequential revenue growth, improving gross margins and continued expense control contributed to better than expected earnings for the quarter,” stated Mory Ejabat, Zhone’s chief executive officer. “We are encouraged by the immediate acceptance of our new products and hope to build on that momentum to achieve our primary goal of reaching quarterly EBITDA profitability by year end.”

Non-GAAP Financial Measures

To supplement Zhone’s consolidated financial statements presented in accordance with GAAP, Zhone uses pro forma EBITDA, a non-GAAP measure Zhone believes is appropriate to enhance an overall understanding of Zhone’s past financial performance and prospects for the future. These adjustments to GAAP results are made with the intent of providing greater transparency to supplemental information used by management in its financial and operational decision-making. These non-GAAP results are among the primary indicators that management uses as a basis for making operating decisions because they provide meaningful supplemental information regarding the company’s operational performance, including the company’s ability to provide cash flows to invest in research and development, and to fund capital expenditures. In addition, these non-GAAP financial measures facilitate management's internal comparisons to the company's historical operating results and comparisons to competitors' operating results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for measures of financial performance prepared in accordance with GAAP. A reconciliation between net loss calculated on a GAAP basis and pro forma EBITDA on a non-GAAP basis is provided in a table immediately following the Unaudited Condensed Consolidated Statements of Operations.
