Fourth Quarter 2013 Results

Commenting on the results, Stephen Tai, Montage Technology’s president stated, “Fourth quarter revenue exceeded our original expectations, growing 17.9% sequentially and 49.5% year-over-year, and was further highlighted by solid gross and operating margin performance. Our results were driven by an 11% sequential increase in our set-top box products, combined with an 86% increase in memory interface revenue with the ramping of our LRDIMM products.

“In the STB market, we continued to gain market share in the emerging markets in which we compete with our integrated satellite solutions for standard definition (SD), while also ramping our high definition (HD) decoder product that we launched in early 2013. Additionally, we recently taped-out integrated SoC solutions for the HD satellite and HD terrestrial markets, in order to fully capitalize on the transition from SD to HD in the emerging markets. These new products allow us to significantly expand our target addressable market.”

Howard Yang, Montage Technology’s chairman and chief executive officer, further added, “Complementing the growth of our set-top box products, memory interface revenue increased 86% sequentially, driven by increased demand for our LRDIMM products following the launch of Intel’s Ivy Bridge platform in September. Servers running on Ivy Bridge can utilize multiple CPUs and more advanced memory configurations, which can require as many as 48 LRDIMM modules per server. As a primary supplier to many of the leading global server OEMs, we see significant growth opportunities in 2014 and believe we are well positioned to gain market share with the increased adoption of the Ivy Bridge platform.”

Total revenue for the fourth quarter 2013 was $35.4 million, an increase of 17.9 percent compared to $30.1 million in the third quarter, and an increase of 49.5 percent compared to $23.7 million in the fourth quarter 2012. Total revenue consisted of $30.2 million from set-top box products, or 85.3 percent of revenue, and $5.2 million from memory interface products, representing 14.7 percent of revenue.

Gross profit for the fourth quarter 2013 was $22.1 million, or 62.4 percent of revenue, compared to $19.1 million, or 63.7 percent of revenue in the prior quarter, and $13.3 million, or 56.3 percent in the fourth quarter 2012. Operating expenses for the fourth quarter 2013 were $13.3 million, compared to $10.5 million in the prior quarter and $9.4 million in the fourth quarter 2012.

Income from operations was $8.9 million, or 25.1 percent of revenue, compared to $8.6 million, or 28.8 percent of revenue in the prior quarter, and $3.9 million, or 16.5 percent of revenue in the fourth quarter 2012.

Fourth quarter 2013 GAAP net income was $8.9 million, or $0.31 per diluted share, compared to third quarter 2013 net income of $8.0 million, or $0.31 per diluted share, and fourth quarter 2012 net income of $3.7 million, or $0.12 per diluted share. The effective tax rate for the fourth quarter 2013 was 3 percent, compared to an effective tax rate of 8 percent in the preceding quarter.

Non-GAAP net income for the fourth quarter 2013 was $10.4 million, or $0.37 per diluted share, which excluded pre-tax stock-based compensation expenses of approximately $1.2 million and $0.3 million of amortization of acquired assets related to an assembled workforce in Taiwan. This compares to non-GAAP net income of $9.5 million, or $0.38 per diluted share, in the third quarter 2013 and $4.3 million, or $0.15 per diluted share, in the fourth quarter 2012.

Cash, cash equivalents and short-term investments totaled approximately $107.7 million as of December 31, 2013, compared to approximately $47.6 million as of September 30, 2013. In its

initial public offering on October 1, 2013, Montage Technology raised $46.9 million in net proceeds, after deducting underwriting discounts and offering expenses, receipt of which occurred in the fourth quarter. The Company generated $12.6 million in cash flow from operations.

In addition, Montage provided the following update regarding allegations made in short seller reports under the banner of Gravity Research. As Montage has previously stated, it believes these allegations are misleading and contain numerous errors of fact. As an additional measure, Montage’s Audit Committee has appointed the global law firm Jones Day to conduct an independent review of the allegations and related matters. The Company believes the results of this independent review will further demonstrate that the allegations by Gravity Research lack merit.

Business Outlook

For the first quarter of 2014, the Company expects revenue to be in the range of $29.0 million to $32.0 million and gross margin to be in the range of 60 percent to 62 percent.

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.
