GAAP earnings were $0.54/diluted share; non-GAAP earnings were $0.78/diluted share

SAN JOSE, Calif. — (BUSINESS WIRE) — October 26, 2017 — Power Integrations (Nasdaq: POWI) today announced financial results for the quarter ended September 30, 2017. Results are calculated using the “sell-in” method of revenue recognition on sales to distributors, reflecting the company’s adoption of ASC 606 effective January 1, 2017. Prior-year results have been recast as if ASC 606 had been in effect for those periods.

Net revenues for the third quarter were $111.3 million, an increase of three percent from the prior quarter and nine percent from the third quarter of 2016. Net income was $16.5 million or $0.54 per diluted share, compared to $0.46 per diluted share in the prior quarter and $0.43 per diluted share in the third quarter of 2016. Cash flow from operations was $24.6 million for the quarter.

In addition to its GAAP results, the company provided certain non-GAAP financial measures that exclude stock-based compensation expenses, amortization of intangible assets and the tax effects of these items. Non-GAAP net income for the third quarter was $23.7 million or $0.78 per diluted share, compared with $0.69 per diluted share in the prior quarter and $0.67 per diluted share in the third quarter of 2016.

Commented Balu Balakrishnan, president and CEO of Power Integrations: “Revenues are up 13 percent for the first nine months of 2017, putting us on course for another year of double-digit revenue growth. We have a broad set of attractive opportunities ahead of us in the high-voltage power conversion market, including global trends such as energy efficiency as well as fast-growing vertical markets like rapid charging, smart homes and clean energy. We have a strong portfolio of products with which to address these opportunities, including our new InnoSwitch™3 family of ICs, which significantly advances the state of the art in power-supply design with its unprecedented levels of integration and energy efficiency.”

Note Regarding Use of Non-GAAP Financial Measures

In addition to the company's consolidated financial statements, which are presented according to GAAP, the company provides certain non-GAAP financial information that excludes stock-based compensation expenses recorded under ASC 718-10, amortization of acquisition-related intangible assets (including in-place lease intangible assets) and the tax effects of these items. The company uses these measures in its financial and operational decision-making and, with respect to one measure, in setting performance targets for compensation purposes. The company believes that these non-GAAP measures offer important analytical tools to help investors understand its operating results, and to facilitate comparability with the results of companies that provide similar measures. These non-GAAP measures have limitations as analytical tools and are not meant to be considered in isolation or as a substitute for GAAP financial information. For example, stock-based compensation is an important component of the company’s compensation mix, and will continue to result in significant expenses in the company’s GAAP results for the foreseeable future, but is not reflected in the non-GAAP measures. Also, other companies, including companies in Power Integrations’ industry, may calculate non-GAAP measures differently, limiting their usefulness as comparative measures. Reconciliations of non-GAAP measures to GAAP measures are attached to this press release.
