SanDisk ( SNDK) reported a third quarter in which revenue doubled from a year ago and earnings rose by a factor of nearly four to blow away Wall Street estimates.

But stranger things lurked lower in the company's earnings release, which was moved up to Wednesday morning from Wednesday evening. According to SanDisk, a lawyer in the company's Taiwanese law firm has fraudulently sold and then misappropriated the proceeds of some $100 million of stock in United Microelectronics ( UMC - Get Report) that was owned by SanDisk in a power-of-attorney account with the firm.

SanDisk noted that the firm, Lee and Li, has given a written assurance that it won't let SanDisk "suffer any loss as a result of its former employee's criminal acts." Nevertheless, SanDisk noted in its release, any amount that isn't fully repaid could result in non-operating accounting charges, and the amount of loss isn't determinable at this time.

The third quarter results the company disclosed Wednesday don't reflect the theft. SanDisk said it earned $50.6 million, or 60 cents a share, on revenue of $281.4 million in the quarter, compared with $11.3 million, or 16 cents a share, on revenue of $141.1 million a year ago.

Analysts surveyed by Thomson First Call were expecting earnings of 44 cents a share on revenue of $248.9 million for the flash-memory maker in the third quarter.

"Bookings during the quarter were exceptionally strong for both our OEM and retail customers," SanDisk noted. "We exceeded our expectations for third quarter product revenues and total megabytes shipped due to excellent execution in operations and the successful conversion to 0.13 micron technology. Product gross margins improved to 35% from 32% in the prior quarter due to the benign pricing environment, as well as higher margin contribution from the increasing sales of Secure Digital cards."

SanDisk's shares weren't doing any volume in the premarket.
