Avago Technologies Updates First Quarter Fiscal 2010 Financial Guidance

SAN JOSE, Calif., and SINGAPORE, January 15, 2010 — Avago Technologies Limited (Nasdaq: AVGO), today announced that, based on preliminary quarter-to-date results, it now expects revenue in the first fiscal quarter ending January 31, 2010 to be up 3.0-5.0% sequentially from the fourth fiscal quarter of 2009. Previous guidance issued on December 3, 2009 had been for revenue to be in the range of flat to down 3% sequentially.

The improvement in forecasted results for the first fiscal quarter is primarily the result of stronger than anticipated sales in the wired infrastructure and industrial target markets. In addition, during the quarter to date the Company has seen a degree of price stabilization across all of its target markets.

The updated financial outlook for the first quarter of fiscal year 2010 from the prior quarter follows:

 

      GAAP    Reconciling Items    Non-GAAP

Revenue

   up 3.0% to 5.0%       up 3.0% to 5.0%

Gross Margin

   41.5% plus/minus 50 bpt.    $15M    45.0% plus/minus 50 bpt.

Operating Expenses

   $117M    $11M    $106M

Interest and Other

   $34M    $24M    $10M

Taxes

   $3M to $4M       $3M to $4M

Diluted Share Count

   245M       248M

Reconciling items include $15M of amortization of acquisition-related intangibles at the Gross Margin line, $5M of amortization of acquisition-related intangibles, $5M of share-based compensation and $1M of restructuring charges at the Operating Expenses line and a $24M loss on extinguishment of the debt that we redeemed in December 2009 at the Interest and Other line.

The guidance provided above is only an estimate of what the Company believes is realizable as of the date of this release. Actual results will vary from the guidance and the variations may be material.

Non-GAAP Financial Measures

In addition to GAAP reporting, consistent with past practice Avago reports net income or loss, as well as gross margin and operating expenses, on a non-GAAP basis. This non-GAAP information excludes amortization of acquisition-related intangibles, share-based compensation expense, asset impairment charges, restructuring charges, acquired in-process research and development, debt extinguishment (gains) losses, advisory agreement termination fee, selling shareholder expenses and the results of discontinued operations. Avago believes this non-GAAP earnings 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 emphasize the results of on-going operations. These non-GAAP measures are in addition to, and not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Secondary Offering

Avago Technologies Limited today also filed with the Securities and Exchange Commission (SEC) a registration statement for a secondary offering of 25.0 million ordinary shares, plus an additional 3.75 million shares subject to the underwriters’ overallotment option.

A registration statement relating to these securities has been filed with the SEC but has not yet become effective.
