Fourth quarter net income was $159 million, or $0.64 per diluted share. This compares with net income of $145 million, or $0.58 per diluted share for the prior quarter, and net income of $154 million, or $0.61 per diluted share in the same quarter last year.

Income from operations was $199 million. This compares with $186 million in the prior quarter and $191 million in the same quarter the previous year.

Net income was $194 million, or $0.77 per diluted share. This compares with net income of $182 million, or $0.72 per diluted share last quarter, and net income of $186 million, or $0.73 per diluted share in the same quarter last year.

“Strong product ramps at major smartphone customers more than offset weakness in industrial and wired infrastructure, resulting in a 2% sequential revenue growth in the fourth quarter. Sequential revenue growth of 8% for our three primary target markets in the quarter was overshadowed by the anticipated $31 million decrease in revenue from our legacy consumer navigation products,” said Hock Tan, President and CEO of Avago Technologies Limited. “Looking to the first fiscal quarter of 2013, however, we expect continued softness in wired infrastructure and continued supply chain contraction in industrial will result in a decrease in revenue.”

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 acquisition-related intangibles, share-based compensation expense, restructuring charges and debt extinguishment losses. 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.
