Inphi Corporation Announces Third Quarter 2011 Results

SANTA CLARA, Calif., October 26, 2011 – Inphi Corporation (NYSE: IPHI), a leading provider of high-speed analog semiconductor solutions for the communications and computing markets, today announced financial results for its third quarter ended September 30, 2011.

Revenue for the third quarter of 2011 was $16.5 million, compared with $21.9 million for the third quarter of 2010.

As reported under U.S. generally accepted accounting principles (GAAP), net loss for the third quarter of 2011 was $2.6 million, or ($0.10) per diluted common share, compared with GAAP net income of $3.6 million, or $0.05 per diluted common share, for the third quarter of 2010. GAAP net income and earnings per share for 2010 reflect in part a large income tax benefit recorded in 2010 related to the release and reversal of valuation allowances against deferred tax assets provided in previous periods.

Gross margin on a GAAP basis for the third quarter of 2011 was 60.1% of revenue, compared with 65.4% of revenue for the third quarter of 2010.

Inphi reports gross margin, net income, and earnings per share in accordance with GAAP and on a non-GAAP basis. A reconciliation of the GAAP to non-GAAP gross margin, net income, and earnings per share, as well as a description of the items excluded from the non-GAAP calculations, is included in the financial statements portion of this news release.

Gross margin on a non-GAAP basis for the third quarter of 2011 was 65.2% of revenue, compared with 65.5% for the third quarter of 2010.

Inphi announced in August 2011 that it had discontinued the sale of some acquired legacy products in Taiwan and transitioned the site to be a design-only center. As a result, the company recorded $1.6 million in a restructuring expense, primarily comprised of the write-off of certain intangible assets, as reflected in this quarter’s GAAP financial statements.

Non-GAAP net income for the third quarter of 2011 was $0.2 million, or $0.01 per diluted common share. This compared with non-GAAP net income of $2.6 million, or $0.13 per diluted share, for the third quarter of 2010. Non-GAAP diluted earnings per share was lower in the third quarter of 2011 due to lower non-GAAP net income, a higher number of shares outstanding related to the company’s issuance of common shares and the conversion of preferred shares into common shares, both in connection with the company’s initial public offering.

“Q3 was a tough quarter,” said Young K. Sohn, President and CEO of Inphi. “Inphi is experiencing near-term macroeconomic headwinds as a part of supply chains that have focused on minimizing inventory risk. As a product cycle-driven company, we expect growth to resume upon the introduction of exciting next-generation platforms. Despite these near-term challenges, our design win pipeline continues to grow. We expect our iMB™ and RDIMM products to benefit from strong demand for next-generation computing platforms in early 2012. In addition, now that our new 100GbE iPHY™ CMOS solutions are sampling, we are working hard to

translate the high degree of interest into additional design wins in both the networking and data center markets. We believe strongly in our growth opportunities for 2012 and beyond.”

Recent Highlights

Nine Months 2011 Results

For the nine months ended September 30, 2011, revenue was $62.0 million, consistent with revenue for the first nine months ended September 30, 2010. GAAP net income for the nine months ended September 30, 2011 was $2.2 million, or $0.08 per diluted share, on approximately 29.4 million diluted weighted average common shares outstanding. This compared with GAAP net income of $23.2 million, or $0.46 per diluted share, on approximately 5.6 million diluted weighted average common shares outstanding for the nine months ended September 30, 2010.

Non-GAAP net income for the nine months ended September 30, 2011 was $7.0 million, or $0.24 per diluted weighted average common share outstanding. This compared with non-GAAP net income of $7.5 million for the nine months ended September 30, 2010, or $0.37 per diluted weighted average common share outstanding, including the assumed conversion of preferred shares into common shares related to the initial public offering, for the nine months ended September 30, 2010.

Business Outlook

The following statements are based on our current expectations for the fourth quarter of 2011. These statements are forward-looking and actual results may differ materially.

• Revenue is expected to be in a range of $15.5-$17.5 million for the fourth quarter of 2011.

• Stock-based compensation expense is expected to be in the range of $2.0 million to $2.1 million.

• GAAP net loss is expected to be in the range of ($1.4) million to ($0.7) million, or ($0.05)-($0.02) per diluted common share, on approximately 27.5 million diluted weighted average common shares outstanding.

• Non-GAAP results, excluding stock-based compensation expense, are expected to be between a net loss of ($0.3) million and net income of $0.6 million, or between ($0.01) -$0.02 per diluted common share.

INPHI CORPORATION

RECONCILIATION OF GAAP TO NON-GAAP MEASURES

(in thousands of dollars, except share and per share amounts)

To supplement the financial data presented on a GAAP basis, the Company discloses certain non-GAAP financial measures, which exclude stock-based compensation, taxes related to the transition to a more international business structure, release of the valuation allowance on our deferred tax assets and restructuring charges of Taiwan subsidiary. It also includes the assumed conversion of all outstanding shares of preferred stock into shares of common stock which occurred in connection with the initial public offering. These non-GAAP financial measures are not in accordance with GAAP. These results should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures. The Company believes that its non-GAAP financial information provides useful information to management and investors regarding financial and business trends relating to its financial condition and results of operations because it excludes charges or benefits that management considers to be outside of the Company’s core operating results. The Company believes that the non-GAAP measures of gross margin, net income, earnings per share and weighted average shares outstanding in combination with the Company’s financial results calculated in accordance with GAAP, provide investors with additional perspective and a more meaningful understanding of the Company’s ongoing operating performance. In addition, the Company’s management uses these non-GAAP measures to review and assess the financial performance of the Company, to determine executive officer incentive compensation and to plan and forecast performance in future periods. The Company’s non-GAAP measurements are not prepared in accordance with GAAP, and are not an alternative to GAAP financial information, and may be calculated differently than non-GAAP financial information disclosed by other companies.
