April 18, 2012

SAN JOSE, Calif., April 18, 2012-Novellus Systems, Inc. (NASDAQ: NVLS) today reported operating results for its first quarter ended March 31, 2012. Net sales for the first quarter were $326.7 million, up $44.0 million or 15.6 percent from fourth quarter 2011 net sales of $282.7 million, and down $86.5 million or 20.9 percent from first quarter 2011 net sales of $413.2 million. Net income for the first quarter was $44.4 million, or $0.59 per diluted share, up $5.9 million from fourth quarter 2011 net income of $38.5 million, or $0.56 per diluted share, and down $51.9 million from first quarter 2011 net income of $96.4 million, or $1.04 per diluted share.

First quarter 2012 results of operations include $2.3 million of costs incurred for the proposed merger with Lam Research Corporation and $0.2 million in restructuring charges. First quarter 2012 net income without those items was $46.0 million, or $0.61 per diluted share. Excluding certain charges, fourth quarter 2011 net income was $30.8 million, or $0.45 per diluted share, and first quarter 2011 net income was $96.5 million, or $1.04 per diluted share. A reconciliation to U.S. generally accepted accounting principles ("GAAP") of our non-GAAP operating results is included below.

Bookings in the first quarter of 2012 were $361.7 million, up $74.6 million or 26.0 percent from fourth quarter 2011 bookings of $287.1 million. First quarter shipments of $319.2 million were up $42.7 million or 15.4 percent from $276.5 million in the fourth quarter of 2011.(1)

Cash, cash equivalents, and short-term investments at the end of the first quarter were $1.0 billion, an increase of $95.2 million or 10.4 percent from the fourth quarter 2011 ending balance of $918.7 million. Long-term investments and non-current restricted cash and cash equivalents at the end of the first quarter were $168.8 million, an increase of $2.7 million or 1.6 percent from the fourth quarter 2011 ending balance of $166.0 million. There were no share repurchases during the first quarter of 2012. Cash flows from operations during the first quarter of 2012 were $32.8 million, down $51.9 million or 61.3 percent from $84.7 million in the fourth quarter of 2011, and down $51.0 million or 60.9 percent from $83.8 million in the first quarter of 2011.

During the fourth quarter of 2011, we reached an agreement with the IRS regarding income tax refunds due to Novellus related to the 2006 and 2007 tax years. Due to the magnitude of the refunds, they are subject to approval by Congress' Joint Committee on Taxation. If the Joint Committee were to approve the refunds, it would result in a tax benefit of approximately $16.0 million. As of March 31, 2012, the refunds are still under review by the Joint Committee. As a result, the $16.0 million benefit recognition has been deferred pending the Joint Committee's final decision.

In accordance with the indenture governing our senior convertible notes, we have notified the holders of our senior convertible notes of the opening of the conversion window and their conversion rights in connection with the proposed merger with Lam Research Corporation. Accordingly, the carrying amount of senior convertible notes has been reclassified from noncurrent to current liabilities in our balance sheet. The excess of the amount of cash payable, if converted, over the carrying amount of the notes has been reclassified from permanent to temporary equity. Should the proposed merger not be completed or when the conversion period closes, 35 days after the completion of the proposed merger, all notes not converted will be reclassified back to noncurrent liabilities and the temporary equity will be reclassified back to permanent equity.

Richard S. Hill, Chairman and Chief Executive Officer, said " Our track record for delivering strong financial performance remained on course with another solid quarter of earnings, thanks to the hard work and dedication of our employees and a culture driven by excellence." Hill added, "With the integration planning between Novellus and Lam Research well underway, I've never been more confident that the combination of these two companies will create the most technologically and financially successful semiconductor capital equipment company in the industry, especially under the leadership team of Martin Anstice and Tim Archer."

(1) Bookings and shipments are non-GAAP measures; they are not in accordance with or an alternative for U.S. GAAP (generally accepted accounting principles) and may be different from similar measures used by other companies. For more information regarding non-GAAP measures, please see footnote (2).

(2) The discussion of bookings and shipments and the presentation of operating expenses, operating income, income before taxes, provision for income taxes, net income, and net income per diluted share, set forth in the table above, each excludes certain charges and benefits and are not in accordance with U.S. GAAP. These measures may differ from non-GAAP methods of accounting and reporting used by other companies. The non-GAAP financial measures we provide have certain limitations because they do not reflect all of the costs associated with the operation of our business as determined in accordance with GAAP. The non-GAAP measures are in addition to, and not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. We endeavor to compensate for the limitations of these non-GAAP measures by providing GAAP financial statements, descriptions of the reconciling items, and a reconciliation of the non-GAAP measures to the most directly comparable GAAP measures so that investors can appropriately incorporate the non-GAAP measures and their limitations into their analyses.

Management uses certain non-GAAP measures to evaluate operating performance. We discuss these non-GAAP measures because we believe they provide additional insight into underlying operating results and prospects for the future, allowing investors to assess certain business trends in the same way that these trends are utilized by management in its financial and operational decision making. Shipments consist of products shipped to customers, without regard to net sales adjustments such as deferrals associated with customer acceptance. Bookings consist of current period orders less current period cancellations and other adjustments. We do not report bookings for systems with delivery dates more than 12 months from the latest balance sheet date. Shipments and bookings are used to forecast and plan future operations. Further, we believe the presentation of non-GAAP measures provides investors with additional insight into underlying operating results by excluding certain charges and benefits related to (i) the IAG building sale, (ii) merger related costs, (iii) restructuring charges, and (iv) certain legal expenses and benefits. These certain charges and benefits may not be indicative of our ongoing operations or economic performance.
