Inphi Corporation Delivers Record Revenue and EPS in Q3 2019

Strong Year-Over-Year Growth Driven by Both Cloud and Telecom

SANTA CLARA, Calif., Oct. 29, 2019 – Inphi Corporation (NYSE: IPHI), a leader in high-speed data movement interconnects, today announced financial results for its third quarter ended September 30, 2019.

GAAP Results

Revenue in the third quarter of 2019 was a record $94.2 million on a U.S. generally accepted accounting principles (GAAP) basis, up 20.8% year-over-year, compared with $78.0 million in the third quarter of 2018. The increase was due to higher demand for long haul, metro and datacenter products.

Gross margin under GAAP in the third quarter of 2019 was 57.8%, compared with 55.7% in the third quarter of 2018. The increase was mainly due to product and revenue mix.

GAAP operating loss in the third quarter of 2019 was $10.9 million or (11.6%) of revenue, compared to GAAP operating loss in the third quarter of 2018 of $16.0 million or (20.6%) of revenue. The decrease in operating loss was mainly due to higher gross profit, partially offset by higher operating expenses.

GAAP net loss for the third quarter of 2019 was $16.2 million or ($0.36) per diluted common share, compared with $22.7 million or ($0.52) per diluted common share in the third quarter of 2018.

Inphi reports gross profit, operating expenses, net income (loss), and earnings per share in accordance with GAAP and on a non-GAAP basis. A reconciliation of the GAAP to non-GAAP gross profit, operating expenses, operating income, net income, 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 press release.

Non-GAAP Results

Gross margin on a non-GAAP basis in the third quarter of 2019 was 70.2%, compared with 69.4% in the third quarter of 2018. The increase was due to a change in product and revenue mix.

Non-GAAP operating income in the third quarter of 2019 was $21.4 million, compared with non-GAAP operating income of $13.5 million in the third quarter of 2018. The increase is primarily due to higher gross profit, partially offset by higher operating expenses.

Non-GAAP net income in the third quarter of 2019 was $21.5 million, or $0.45 per diluted common share. This compares with non-GAAP net income of $13.7 million, or $0.30 per diluted common share in the third quarter of 2018.

“We are very pleased to have exceeded the high-end of our revenue and EPS guidance in Q3, delivering record results driven by strength in both Cloud and Telecom,” said Ford Tamer, President and CEO of Inphi Corporation. “The 50% year-on-year non-GAAP EPS growth in Q3, based on 21% year-on-year revenue growth, demonstrates the leverage in our operating model as we execute on our customer growth strategy.”

Nine Months 2019 Results

Revenue in the nine months ended September 30, 2019 was $262.7 million, compared with $208.0 million in the nine months ended September 30, 2018. GAAP net loss in the nine months ended September 30, 2019 was $59.5 million, or ($1.32) per diluted common share, on approximately 45.1 million diluted weighted average common shares outstanding. This compares with GAAP net loss of $74.1 million, or ($1.70) per diluted common share, on approximately 43.5 million diluted weighted average common shares outstanding in the nine months ended September 30, 2018.

Non-GAAP net income in the nine months ended September 30, 2019 was $53.5 million, or $1.14 per diluted common share, on approximately 47.1 million non-GAAP diluted weighted average common shares outstanding. This compares with non-GAAP net income of $18.3 million in the nine months ended September 30, 2018, or $0.41 per diluted common share, on approximately 44.8 million diluted weighted average common shares outstanding.

The following table presents details of stock-based compensation expense included in each functional line item in the consolidated statements of operations above: 

To supplement the financial data presented on a GAAP basis, the Company discloses certain non-GAAP financial measures, which exclude stock-based compensation, legal, transition costs and other expenses, purchase price fair value adjustments related to acquisitions, loss on claim settlements, non-cash interest expense related to convertible debt, unrealized gain or loss on equity investments and deferred tax asset valuation allowance. 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, income from operations, net income and earnings per share, 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.
