Heavy reliance on single customer

InvenSense ( INVN ) makes motion sensors for consoles and tablets. It relies on Samsung (OTC:SSNLF) for over 30% of total revenue. The company guided third quarter revenue and earnings lower than consensus.

InvenSense expects revenue to be $65 – $68 million, with earnings as high as $0.18 per share. The consensus was $0.22 per share on revenue of $76.6 million. The trouble for InvenSense may be that it built up inventory, but did not yet have firm orders from console companies to include in its forecast.

Cirrus Logic ( CRUS ) also relies heavily on one customer: Apple (AAPL). Investors were disappointed that Cirrus lowered its gross margin forecast from 52% down to between 45% – 47%. The current quarter was supposed to be the company’s strongest quarter. 

Hazy forecast

And Silicon Graphics ( SGI ) deferred providing guidance, giving investors a reason to sell shares. The company blamed a lack of clarity on expected government spending.

In its last quarter ended September 27, Silicon Graphics earned $0.04 per share, beating estimates by $0.02 per share. Revenue was $148 million.
