Second Quarter Fiscal Year 2013 GAAP Results

Net revenue was $562 million, a decrease of 2 percent compared with the previous quarter and a decrease of 3 percent from the same quarter last year.

Gross margin was $272 million, or 48.4 percent of net revenue. This compares with gross margin of $276 million, or 47.9 percent of net revenue last quarter, and gross margin of $278 million, or 48.2 percent of net revenue in the same quarter last year.

Operating expenses were $154 million. This compares with $152 million in the prior quarter and $141 million for the same quarter the previous year.

Income from operations was $118 million. This compares with $124 million in the prior quarter and with $137 million in the same quarter last year.

Second quarter net income was $113 million, or $0.45 per diluted share. This compares with net income of $125 million, or $0.50 per diluted share for the prior quarter, and net income of $134 million, or $0.54 per diluted share in the same quarter last year.

The Company’s cash balance at the end of the second quarter was $1,219 million, compared to $1,151 million at the end of the prior quarter.

The Company generated $191 million in cash from operations in the second quarter and spent $47 million on capital expenditures. On April 4, 2013 the Company paid a quarterly cash dividend of 19 cents ($0.19) per ordinary share, totaling approximately $47 million. The company also closed an acquisition during the second fiscal quarter for an aggregate acquisition cost of approximately $37 million in cash.

In April 2013, Avago announced the acquisition of CyOptics, Inc. for total consideration of approximately $400 million. The Company expects to close this transaction in its third fiscal quarter of 2013, subject to the satisfaction of customary closing conditions, including the receipt of regulatory approvals in the United States.

Second Quarter Fiscal Year 2013 Non-GAAP Results

Gross margin was $288 million, or 51.2 percent of net revenue. This compares with gross margin of $292 million, or 50.7 percent of net revenue last quarter, and gross margin of $295 million, or 51.1 percent of net revenue in the same quarter last year.

Income from operations was $158 million. This compares with $162 million in the prior quarter and $171 million in the same quarter the previous year.

Net income was $153 million, or $0.61 per diluted share. This compares with net income of $163 million, or $0.65 per diluted share last quarter, and net income of $168 million, or $0.66 per diluted share in the same quarter last year.

“During the second fiscal quarter, revenues came in at the upper end of our guidance helped by improved resales at our distributors in our industrial business,” said Hock Tan, President and CEO of Avago Technologies Limited. “Looking to the third quarter, we see broad-based improvement across all three of our end markets. We believe that the initial ramp of a product transition at a large smartphone OEM, a recovery in enterprise networking spending, as well as a continued, gradual uptick in industrial end market demand, could drive a sequential growth up to high single digits on a percentage basis.”

Non-GAAP Financial Measures

In addition to GAAP reporting, Avago provides investors with net income, income from operations, gross margin, operating expenses and other data, on a non-GAAP basis. This non-GAAP information excludes amortization of intangible assets, share-based compensation expense restructuring charges and acquisition-related costs. Management does not believe that the excluded items are reflective of the Company’s underlying performance. The exclusion of these and other similar items from Avago’s non-GAAP presentation should not be interpreted as implying that these items are non-recurring, infrequent or unusual. Avago believes this non-GAAP financial information provides additional insight into the Company’s on-going performance and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company’s on-going operations and enable more meaningful period to period comparisons. These non-GAAP measures are provided in addition to, and not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. A reconciliation between GAAP and non-GAAP financial data is included in the supplemental financial data attached to this press release.
