Exhibit 99.1 Semtech Announces First Quarter Results CAMARILLO, Calif.--(BUSINESS WIRE)--May 31, 2005--Semtech Corporation (NASDAQ:SMTC), a leading producer of high performance analog and mixed-signal semiconductors, today announced financial results for its first quarter of fiscal year 2006 that ended May 1, 2005. Net sales for the first quarter of fiscal year 2006 were $56.2 million, down 4 percent sequentially from the fourth quarter and down 9 percent from the prior year first quarter. Net income for the first quarter was $10.8 million or 14 cents per diluted share, compared to net income of $14.8 million or 19 cents per diluted share in the prior year period. Semtech generated $13.4 million of operating cash flow and spent $8.7 million on stock buybacks in the first quarter of fiscal year 2006. New orders in the first quarter of fiscal year 2006 were up 3 percent from the fourth quarter, but were less than shipments in the period. Orders for the Company's Protection and SETS product lines reached record levels in the first quarter. Order levels in certain areas of power management were impacted by lower average selling prices. New proprietary product introductions are forecasted to drive future order growth and margin expansion. The Networking and Industrial Power Management product line experienced record orders in the first quarter and continued strong new product introductions. The Company is also seeing diversity into broader end-markets, such as high-end consumer products. Customers continue to order and request shipments with very short lead-times and are avoiding building buffer inventory levels. Shipments by Semtech distributors to end-customers within Asia were at a record level in first quarter, indicating a continued decline in channel inventories. As the end-markets improve, demand should reflect the lower inventories and improving market conditions. The Company introduced 23 new products in the first quarter of fiscal year 2006. Nine of the new products were in the area of Portable Power Management and 8 were out of the Protection Products group. The rate of new product introductions is up dramatically over the prior year period, due in part to improved product definition and design processes implemented last year. Second Quarter Outlook Semtech estimates that net sales for the second quarter that ends July 31, 2005 will be approximately flat with the first quarter that ended May 1, 2005. Turns orders (orders received and shipped in the same quarter) of approximately 48 percent are required to achieve this forecast. Earnings in the second quarter are forecasted to be 14 cents per diluted share.
