Multi-Fineline Electronix (NASDAQ: MFLX) has reported preliminary numbers for its fiscal 1Q 2013 in an official press release. Its net sales will amount to $290 million, or a 21% improvement from the same quarter the previous year. The former number is above the $260 million-$280 million range provided earlier by the firm.

Profitability is expected to come in lower than the existing guidance, however. The company said gross margin for 1Q 2013 will be roughly 8.5%, well below the 10%-12% it forecast at the end of last year.

Multi-Fineline Electronix will report a full set of results for the quarter on Feb. 7.
