MEMSIC Announces First-Quarter 2013 Results

ANDOVER, Mass., May 13, 2013 – MEMSIC, Inc. (NasdaqGM: MEMS), a leading MEMS sensing solution provider, today announced financial results for the first quarter ended March 31, 2013.

● Net sales totaled $11.4 million compared to $20.0 million in the 2012 quarter.

● Gross margin was 36.4% compared to 37.1% in the 2012 quarter.

● Operating expenses totaled $6.8 million compared to $6.2 million in the 2012 quarter.

● GAAP net loss was $2.5 million, or $0.10 per diluted share, compared to net income of $1.2 million, or $0.05 per diluted share, in the 2012 quarter.

● EBITDA was ($1.3) million compared to $2.5 million in the 2012 quarter.

MEMSIC Chairman, President and CEO Dr. Yang Zhao commented, “Our results for the quarter were within the guidance range we previously provided. During the period, we made additional progress with our strategy to capitalize on the large China mobile market. Our ongoing penetration of that market helped mitigate the impact of reduced shipments to a large mobile customer. Our sales to that customer peaked in the first quarter of 2012, affecting our quarter-over-quarter comparisons. In addition, we remain focused on using MEMSIC’s cutting-edge technology to develop high-performance products for the industrial and automotive markets”

In light of MEMSIC’s pending acquisition by IDG-Accel China Capital II, L.P. and its affiliates, announced on April 23, 22013, MEMSIC will not conduct a conference call to review its first-quarter 2013 financial results.

About Non-GAAP Financial Information

EBITDA is a measure used by management to evaluate the Company’s ongoing operations and as a general indicator of its operating cash flow (in conjunction with a cash flow statement that also includes, among other items, changes in working capital and the effect of non-cash charges). The Company defines EBITDA as net income, plus interest expense net of interest income, provision for income taxes, and depreciation and amortization. Management believes EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties in the comparative evaluation of companies. Because not all companies use identical calculations, the Company's presentation of EBITDA and EBITDA per share may not be comparable to similarly titled measures of other companies. EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, EBITDA is not intended to be a measure of free cash flow for management's discretionary use as it does not reflect certain cash requirements such as interest payments, tax payments and debt service requirements.

Pursuant to the requirements of Regulation G, we have provided a reconciliation of EBITDA to GAAP net income as an exhibit to this release.
