SHANGHAI, China – November 7, 2013 – Montage Technology Group Limited (Nasdaq: MONT) (“Montage”), a global fabless provider of analog and mixed-signal semiconductor solutions addressing the home entertainment and cloud computing markets, today announced financial results for the third quarter ended September 30, 2013.

Third Quarter 2013 Highlights:

Third Quarter 2013 Results

Commenting on the quarter, Howard Yang, Montage Technology’s chairman and chief executive officer, stated, “We are pleased to report third quarter revenue increased 19% sequentially and 46% year-over-year, driven by strong growth in the set-top box market combined with improving revenue from our memory interface products. We continued to convert set-top box customers to our SoC chipset, which offers a complete solution of integrated hardware and software. The pace of set-top box adoption in emerging markets has been accelerating as disposable income and consumer demand for better entertainment are increasing. Additionally, digital transmission and HD television are only in the early stages of adoption, which we believe provides significant future growth opportunities for Montage.

“In the memory interface market, during the quarter we introduced the industry’s first production ready dual-mode DDR4 Registering Clock Driver that supports both RDIMM and LRDIMM modules for use in next generation server platforms. This product complements our existing DDR3 solutions and enhances our current product offerings. With this market in its early stages of growth and development, Montage is well established as a primary supplier to all of the largest OEMs.”

Stephen Tai, Montage Technology’s president added, “The successful completion of our initial public offering on October 1st represented a significant milestone for the Company. We believe that Montage is well positioned for growth in the coming quarters as we continue to gain market share with our existing products as well as our newly released products in both the set-top box and memory interface markets.”

In addition to disclosing financial results calculated in accordance with U. S. generally accepted accounting principles (GAAP), the operating results presented contain non-GAAP financial measures that exclude the income statement effects of share-based compensation expense and amortization of acquired intangible assets of assembled workforce in Taiwan.

Management believes it is useful to provide these non-GAAP financial measures and a reconciliation to comparable GAAP financial measures as we believe non-GAAP measures provide useful supplemental information for investors to evaluate our operating results in the same manner as the research analysts that follow Montage, all of whom present non-GAAP projections in their published reports. As such, non-GAAP measures provided by Montage facilitate a more direct comparison of its performance with the financial projections published by the analysts. The items reconciling GAAP financial measures to non-GAAP financial measures and additional comments and the usefulness of each item are set forth below:

Non-GAAP financial measures are not prepared in accordance with GAAP; therefore, the information is not necessarily comparable to other companies’ financial information and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.
