Exhibit 99.1 Catalyst Semiconductor Reports 1st Quarter Results SANTA CLARA, Calif.--(BUSINESS WIRE)--Sept. 5, 2006--Catalyst Semiconductor, Inc. (Nasdaq:CATS), a developer and marketer of programmable and analog/mixed signal products used in telecommunications, networking systems, computation, automotive, industrial and consumer markets, today reported financial results for its first fiscal quarter ended July 31, 2006. For the first fiscal quarter ended July 31, 2006, Catalyst had a net loss of $228,000, or ($0.01) per share, on net revenue of $15.2 million. This compares with net income of $495,000, or $0.03 per diluted share, on net revenue of $14.7 million in the first quarter ended July 31, 2005. For the fourth quarter ended April 30, 2006, Catalyst reported net income of $270,000, or $0.02 per diluted share, on net revenue of $14.2 million. The first quarter net loss results from lower gross margins and the impact of stock option compensation expense. Total stock option related compensation expense was $478,000, and is a result of the adoption of FAS123R in the first fiscal quarter ended July 31, 2006. Net revenue from analog/mixed signal products increased to $1.4 million, or 9.4% of net revenue, in the quarter ended July 31, 2006, compared to $1.1 million, or 7.3% of net revenue, in the quarter ended July 31, 2005 and $1.2 million, or 8.2% of net revenue, in the quarter ended April 30, 2006. Gross margin for the quarter ended July 31, 2006 was 32.2%, compared with 39.0% for the quarter ended July 31, 2005 and 34.9% for the quarter ended April 30, 2006. The gross margin decrease from the previous quarter is primarily attributable to a decline in average selling prices due to product mix and sales of more expensive inventory acquired in previous quarters. Research & Development expense was $1.8 million for the quarter ended July 31, 2006, unchanged from $1.8 million for the quarters ended July 31, 2005 and April 30, 2006. Sales, General and Administrative expense was $3.9 million for the quarter ended July 31, 2006, compared to $3.4 million for the quarters ended July 31, 2005 and April 30, 2006. The increase from the previous quarters is principally attributable to compensation expense associated with outstanding stock option grants to sales, marketing and administrative personnel and the annual program grant to directors. Catalyst recorded a tax benefit of $240,000, or 51.2% of loss before taxes during the quarter ended July 31, 2006. This compares to a tax provision of $247,000 in the quarter ended July 31, 2005 and a tax benefit of $216,000 in the quarter ended April 30, 2006. As of July 31, 2006, Catalyst had cash, cash equivalents and short-term investments of $26.3 million, compared to $29.1 million as of April 30, 2006. The decrease of $2.8 million was primarily due to the purchase of $1.5 million of additional inventory and the acquisition of $1.0 million in fixed assets including $560,000 for refurbishment of the company's new owned headquarters facility located in Santa Clara, California, to which Catalyst relocated in August. Management Comments & Outlook "We continue to see competitive pressure on our product margins, particularly in the memory product lines. We believe that our ongoing transition to .35 micron products and other cost cutting measures will have a positive effect on our margins when more fully implemented. It is noteworthy that the stock option expenses of $478,000 adversely impacted our operating results," said Gelu Voicu, president and chief executive officer. "Another sign of progress is that analog product sales reached $1,425,000, or 9.4% of our net revenue in this quarter. We are encouraged that net revenue for our EEPROM memory products is also increasing and hope to see this trend continue," he added. Additional Events Catalyst recently formed a new wholly owned subsidiary, Catalyst Semiconductor Thailand, Ltd. to serve as its operating center for the management of its inventory and other key activities. Additionally, the Board of Directors of Catalyst announced that Dr. Roland Duchatelet, a member of the board since 1999, has joined the Company's audit committee as its fourth member.
