Calix Reports Third Quarter 2011 Financial Results

October 20, 2011

PETALUMA, CA, Oct 20, 2011 (MARKETWIRE via COMTEX) --

Calix Inc. (NYSE: CALX) today announced unaudited financial results for the third quarter ended September 24, 2011. Revenue for the third quarter of 2011 was $83.7 million, an increase of 11% compared to $75.5 million for the third quarter of 2010. The company reported preliminary estimates for its third quarter results on September 27, 2011 of revenue between $83 and $85 million and non-GAAP earnings per share of $0.07 to $0.09 per share.

"While we are clearly disappointed with our Q3 results, we remain focused on bringing industry leading broadband access solutions to our existing and expanding base of customers," said Carl Russo, president and CEO of Calix. "After what we anticipate will be a pause in our growth, we are looking ahead and building a stronger company to address the secular growth drivers in front of us."

Non-GAAP net income for the third quarter of 2011 was $3.6 million, or $0.07 per fully diluted share, a decrease of 39% compared to non-GAAP net income of $5.8 million, or $0.15 per fully diluted share, for the third quarter of 2010. A reconciliation of GAAP and non-GAAP results is included as part of this release.

GAAP net loss for the third quarter of 2011 was $6.9 million, or $(0.15) per basic and diluted share, compared to a GAAP net loss of $5.4 million, or $(0.14) per basic and diluted share for the third quarter of 2010. A reconciliation of our third quarter 2011 operating results from non-GAAP to GAAP is provided below:

Use of Non-GAAP Financial Information

The Company uses certain non-GAAP financial measures in this press release to supplement its consolidated financial statements, which are presented in accordance with GAAP. These non-GAAP measures include non-GAAP net income and non-GAAP basic and diluted income per share. These non-GAAP measures are provided to enhance the reader's understanding of the Company's operating performance as they primarily exclude certain non-cash charges for stock-based compensation and amortization of acquisition-related intangible assets, and non-recurring merger-related and other expenses, which the Company believes are not indicative of its core operating results. Merger-related and other expenses largely include the charge resulting from the required revaluation of Occam inventory to its estimated fair value, legal and professional expenses, and severance and integration-related expenses and inventory-related charges associated with our merger with Occam. Management believes that the non-GAAP measures used in this press release provide investors with important perspectives into the Company's ongoing business performance and management uses these non-GAAP measures to evaluate financial results and to establish operational goals. The presentation of these non-GAAP measures is not meant to be a substitute for results presented in accordance with GAAP, but rather should be evaluated in conjunction with those GAAP results. A reconciliation of the non-GAAP results to the most directly comparable GAAP results is provided in the financial schedules portion of this press release. The non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies.

This press release contains forward-looking statements, including a resumption of growth, that are based upon management's current expectations and are inherently uncertain. Forward-looking statements are based upon information available to us as of the date of this release, and we assume no obligation to revise or update any such forward-looking statement to reflect any event or circumstance after the date of this release, except as required by law. Actual results and the timing of events could differ materially from current expectations based on risks and uncertainties affecting the Company's business. The reader is cautioned not to unduly rely on the forward-looking statements contained in this press release. Additional information on potential factors that could affect Calix's results and other risks and uncertainties are detailed in its various SEC reports, including its Form 10-Q for the fiscal quarter ended June 25, 2011, filed with the SEC on July 22, 2011, available at http://www.sec.gov.
