Super Micro Computer Inc. Provides First Quarter Financial Update and Schedules Conference Call and Webcast for Final First Quarter Fiscal 2013 Financial Results

SAN JOSE, Calif., October 9, 2012 (BUSINESS WIRE) — Super Micro Computer, Inc. (NASDAQ:SMCI), the leader in server technology innovation and green computing, today provided preliminary information regarding its financial results for the first fiscal quarter ended September 30, 2012.

The Company also announced that it will release final first quarter fiscal 2013 financial results on Tuesday, October 23, 2012, immediately after the close of regular trading, followed by a teleconference beginning at 2:00 p.m. (Pacific Time).

The Company now anticipates that it will report revenue for its first quarter of fiscal 2013 of approximately $270 million. This compares to the Company’s previous guidance range of $270 to $290 million.

Non-GAAP gross margin is expected to be about 13%. The primary cause for the lower gross margin was the steep price drops for hard disk drives and memory. Margins on other products and components were stable to higher.

The Company anticipates that it will report non-GAAP operating expenses for the quarter in line with those reported for the prior quarter ended June 30, 2012.

“Revenue for the quarter was up about 9% from last year and down slightly from our record last quarter despite challenges from a weaker global economy. The big price drops of HDD and memory, particularly late in the quarter, negatively impacted our net profit for the quarter as we adjusted to vendor contracts we entered into in the March quarter.” said Charles Liang, Chairman and CEO. “This quarter we experienced stronger demand for our new Sandybridge product lines suggesting a positive ramp for this new technology. In addition, late in the quarter, we began shipping our new Fat Twin architecture which is a benchmarked leader in performance, power efficiency and cost. We believe that we are well positioned in the market and we will provide more details on the earnings call.”

The preliminary fiscal first quarter financial results presented in this press release are estimates and remain subject to finalization and review.
