•		Non-GAAP Operating Margin of 25.1 percent

MOUNTAIN VIEW, Calif. — Oct. 27, 2010 — Symantec Corp. (Nasdaq:SYMC) today reported the results of its second quarter of fiscal year 2011, ended Oct. 1, 2010. GAAP revenue for the fiscal second quarter was $1.480 billion, up 2 percent year-over-year after adjusting for currency.

“I am pleased with the execution in the quarter, in particular the strong performance in backup and archiving and continued momentum in hosted services and data loss prevention. In addition, we saw growth in the public sector, driven by strength across all product lines in both the civilian and defense agencies,” said Enrique Salem, president and chief executive officer, Symantec. “We’re making good progress integrating the VeriSign security business, PGP and GuardianEdge into the Symantec portfolio and all three acquisitions performed better than expected in the quarter.”

“In the September quarter, we delivered better than expected results on all of our key financial metrics. Our enterprise business closed the quarter on a strong note, generating greater than expected revenue and deferred revenue,” said James Beer, executive vice president and chief financial officer, Symantec. “We also generated another quarter of excellent cash flow from operations, up 37 percent year-over-year, for a total of $1.74 billion over the last twelve months.”

GAAP Results: GAAP operating margin for the second quarter of fiscal year 2011 was 14.7 percent. GAAP net income for the fiscal second quarter was $136 million compared with net income of $155 million for the same quarter last year. GAAP diluted earnings per share were $0.17 compared with $0.19 for the same quarter last year.

GAAP deferred revenue as of Oct. 1, 2010, was $3.104 billion compared with $2.905 billion as of Oct. 2, 2009, up 7 percent on an actual and currency-adjusted basis. Cash flow from operating activities for the second quarter of fiscal year 2011 was $310 million. Symantec ended the quarter with cash, cash equivalents and short-term investments of $2.264 billion.

Non-GAAP Results: Non-GAAP operating margin for the second quarter of fiscal year 2011 was 25.1 percent. Non-GAAP net income for the second quarter was $266 million compared with $295 million for the year-ago period. Non-GAAP diluted earnings per share were $0.34 compared with earnings per share of $0.36 for the year-ago quarter.

As previously announced, Symantec is no longer reporting revenue and deferred revenue on a non-GAAP basis. For a detailed reconciliation of our GAAP to non-GAAP results, please refer to the attached consolidated financial statements.

During the second quarter of fiscal year 2011, Symantec repurchased approximately 17 million shares for $225 million at an average price of $13.16. Symantec has $322 million remaining in the current board authorized stock repurchase plan.

Business Segment and Geographic Highlights

For the September quarter, Symantec’s Consumer segment represented 32 percent of total revenue. During the quarter, Symantec made a one-time reduction to Consumer segment revenue of approximately $10 million resulting from certain consumers not receiving their subscription entitlements on a timely basis. Excluding this adjustment, Symantec’s Consumer segment revenue increased 3 percent year-over-year (increased 5 percent after adjusting for currency).

For the quarter, Symantec’s Security and Compliance segment represented 24 percent of total revenue and increased 5 percent year-over-year (increased 7 percent after adjusting for currency). The Storage and Server Management segment represented 38 percent of total revenue and declined 1 percent year-over-year (increased 1 percent after adjusting for currency). Services represented 6 percent of total revenue and declined 11 percent year-over-year (declined 9 percent after adjusting for currency).

International revenue represented 50 percent of total revenue in the second quarter of fiscal year 2011 and declined 1 percent year-over-year (increased 3 percent after adjusting for currency). The Europe, Middle East and Africa region represented 28 percent of total revenue for the quarter and declined 9 percent year-over-year (flat after adjusting for currency). The Asia Pacific/Japan revenue for the quarter represented 17 percent of total revenue and increased 11 percent year-over-year (increased 5 percent after adjusting for currency). The Americas, including the United States, Latin America and Canada, represented 55 percent of total revenue and increased 3 percent year-over-year on an actual and currency-adjusted basis.

Acquisition Highlights

Symantec completed the acquisition of VeriSign’s security business in early August. The VeriSign security acquisition performed better than expected, generating revenue of $18 million. The June quarter PGP and Guardian Edge acquisitions continue to perform well, generating revenue of $15 million. The combined earnings per share dilution of these acquisitions was 3 cents, which was one penny less dilutive than our expectations of $0.04. Sales and technology integration is progressing well, with the sales teams working on cross-selling opportunities, and acquired technologies being leveraged across the Symantec product portfolio.

Third Quarter Fiscal Year 2011 Guidance

Guidance assumes an exchange rate of $1.35 per Euro for the December 2010 quarter versus the actual weighted average rate of $1.48 per Euro for the December 2009 quarter, approximately a 10 percent currency headwind. The end of period rate for the December 2009 quarter was $1.43, approximately a 6 percent headwind versus the $1.35 per Euro assumption for the December 2010 quarter.

For the third quarter of fiscal year 2011, ending Dec. 31, 2010, revenue is estimated between $1.57 billion and $1.59 billion, up 2 to 3 percent year-over-year and up 3 to 4 percent after adjusting for currency.

GAAP diluted earnings per share are estimated between $0.23 and $0.24. Non-GAAP diluted earnings per share are estimated between $0.32 and $0.33.

Deferred revenue is expected to be in the range of $3.19 billion and $3.22 billion, up 5 to 6 percent year-over-year on an actual and currency-adjusted basis.

SYMANTEC CORPORATION
Explanation of Non-GAAP Measures
Appendix A

The non-GAAP financial measures included in the tables adjust for the following items: business combination accounting entries, stock-based compensation expense, restructuring charges, charges related to the amortization of intangible assets and acquired product rights, impairments of assets and certain other items. We believe the presentation of these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provides meaningful supplemental information regarding the Company’s operating performance for the reasons discussed below. Our management uses these non-GAAP financial measures in assessing the Company’s operating results, as well as when planning, forecasting and analyzing future periods. We believe that these non-GAAP financial measures also facilitate comparisons of the Company’s performance to prior periods and to our peers and that investors benefit from an understanding of these non-GAAP financial measures.

Stock-based compensation: Consists of expenses for employee stock options, restricted stock units, restricted stock awards and our employee stock purchase plan determined in accordance with the authoritative guidance on stock-based compensation. When evaluating the performance of our individual business units and developing short and long term plans, we do not consider stock-based compensation charges. Our management team is held accountable for cash-based compensation, but we believe that management is limited in its ability to project the impact of stock-based compensation and accordingly is not held accountable for its impact on our operating results. Although stock-based compensation is necessary to attract and retain quality employees, our consideration of stock-based compensation places its primary emphasis on overall shareholder dilution rather than the accounting charges associated with such grants. In addition, for comparability purposes, we believe it is useful to provide a non-GAAP financial measure that excludes stock-based compensation in order to better understand the long-term performance of our core business and to facilitate the comparison of our results to the results of our peer companies. Furthermore, unlike cash-based compensation, the value of stock-based compensation is determined using a complex formula that incorporates factors, such as market volatility, that are beyond our control.

Amortization of acquired product rights and other intangible assets: When conducting internal development of intangible assets, accounting rules require that we expense the costs as incurred. In the case of acquired businesses, however, we are required to allocate a portion of the purchase price to the accounting value assigned to intangible assets acquired and amortize this amount over the estimated useful lives of the acquired intangibles. The acquired company, in most cases, has itself previously expensed the costs incurred to develop the acquired intangible assets, and the purchase price allocated to these assets is not necessarily reflective of the cost we would incur in developing the intangible asset. We eliminate these amortization charges from our non-GAAP operating results to provide better comparability of pre and post-acquisition operating results and comparability to results of businesses utilizing internally developed intangible assets.

Restructuring and transformation: We have engaged in various restructuring activities over the past several years that have resulted in costs associated with severance, benefits, outplacement services and excess facilities. Each restructuring has been a discrete event based on a unique set of business objectives or circumstances, and each has differed from the others in terms of its operational implementation, business impact and scope. We do not engage in restructuring activities in the ordinary course of business. While our operations previously benefited from the employees and facilities covered by our various restructuring charges, these employees and facilities have benefited different parts of our business in different ways, and the amount of these charges has varied significantly from period to period. We believe that it is important to understand these charges; however, we do not believe that these charges are indicative of future operating results and that investors benefit from an understanding of our operating results without giving effect to them.

Loss and impairment of assets held for sale: We have committed to sell certain buildings and land. We have classified these assets as held for sale and adjusted the assets’ carrying value when above the fair market value less cost to sell. We do not believe that these charges are indicative of future operating results and believe that investors benefit from an understanding of our operating results without giving effect to them.

Acquisition related expenses: New authoritative guidance on business combinations requires us to record in the statement of operations, certain items that at the time of an acquisition would have been recorded to goodwill under the old authoritative guidance. We have excluded the effect of acquisition related expenses from our non-GAAP operating expenses and net income measures. We incurred expenses in connection with our acquisitions, which we generally would not have otherwise incurred in the periods presented as a part of our continuing operations. Acquisition related expenses consist of professional service expenses. We believe it is useful for investors to understand the effects of these items on our operations. Although acquisition related expenses generally diminish over time with respect to past acquisitions, we generally will incur these expenses in connection with any future acquisitions.

Internally developed software costs: During the three months ended October 1, 2010, the Company reduced research and development expense by approximately $10 million related to increased capitalization of certain costs for internally developed software. This approach aligns the capitalization policies of the business we acquired from VeriSign with the equivalent policies previously utilized by our Hosted Services operation. The Company determined that this change was not material to previously reported results. The Company’s management excluded this immaterial item when evaluating its ongoing operating performance, and therefore excluded this benefit when presenting non-GAAP financial measures.

Explanation of Non-GAAP Measures
Appendix A (continued)

Non-cash interest expense: Effective April 4, 2009, we adopted new authoritative guidance on convertible debt instruments, which changes the method of accounting for our convertible notes. Under this new authoritative guidance, our EPS and net income calculated in accordance with GAAP will be reduced as a result of recognizing incremental non-cash interest expense. We believe it is useful to provide a non-GAAP financial measure that excludes this incremental non-cash interest expense in order to better understand the long-term performance of our core business and to facilitate the comparison of our results to the results of our peer companies.

Loss on early extinguishment of debt: In September 2010, we purchased $500 million of aggregate principal amount of our 0.75% Convertible Senior Notes due June 15, 2011, from several holders in privately negotiated transactions for approximately $497 million net, in cash. The transaction resulted in a loss from extinguishment of debt of approximately $16 million, which represented the difference between the book value of the notes, net of the remaining unamortized discount prior to repurchase and the fair value of the liability component of the notes upon repurchase. We do not believe that this charge is indicative of future operating results and believe that investors benefit from an understanding of our operating results without giving effect to this transaction.

Gain on sale of marketable securities: This constitutes the gain from the sale of the Company’s available-for-sale securities. The Company’s management excludes this gain when evaluating its ongoing performance and therefore excludes this gain when presenting non-GAAP financial measures.

Joint venture: As noted above, we exclude amortization of other intangible assets related to the joint venture from our non-GAAP net income.
