Cadence Reports First Quarter 2017 Financial Results

SAN JOSE, Calif. — April 24, 2017 — Cadence Design Systems, Inc. (NASDAQ: CDNS) today announced results for the first quarter 2017.

Cadence reported first quarter 2017 revenue of $477 million, compared to revenue of $448 million reported for the same period in 2016. On a GAAP basis, Cadence recognized net income of $68 million, or $0.25 per share on a diluted basis, in the first quarter of 2017, compared to net income of $51 million, or $0.17 per share on a diluted basis, for the same period in 2016.

Using the non-GAAP measure defined below, net income in the first quarter of 2017 was $89 million, or $0.32 per share on a diluted basis, as compared to net income of $86 million, or $0.28 per share on a diluted basis, for the same period in 2016.

“Consistent execution enabled Cadence to deliver strong results.  Innovation is at the heart of our success and we have introduced three significant new products so far in 2017:  Xcelium™ for parallel logic simulation, Protium™ S1 for advanced FPGA-based prototyping and Pegasus™ Verification System, a next generation physical verification solution,” said Lip-Bu Tan, president and chief executive officer.  “Additionally, our digital and signoff solutions continue to proliferate with market-shaping customers for the most complex designs at the most advanced nodes.” 

“Cadence met or exceeded its key operating metrics in the first quarter, and we are maintaining our outlook for the fiscal year,” said Geoff Ribar, senior vice president and chief financial officer.

GAAP to Non-GAAP Reconciliation

Non-GAAP financial measures should not be considered as a substitute for or superior to measures of financial performance prepared in accordance with generally accepted accounting principles, or GAAP. Investors are encouraged to review the reconciliation of non-GAAP financial measures contained within this press release with their most directly comparable GAAP financial results. Investors are also encouraged to look at the GAAP results as the best measure of financial performance.

To supplement Cadence’s financial results presented on a GAAP basis, Cadence management uses non-GAAP measures that it believes are helpful in understanding Cadence’s performance. One such measure is non-GAAP net income, which is a financial measure not calculated under GAAP. Non-GAAP net income is calculated by Cadence management by taking GAAP net income and excluding, as applicable, amortization of intangible assets, stock-based compensation expense, acquisition and integration-related costs including retention expenses, investment gains or losses, income or expenses related to Cadence’s non-qualified deferred compensation plan, restructuring and other significant items not directly related to Cadence’s core business operations, and the income tax effect of non-GAAP pre-tax adjustments.

Cadence’s management uses non-GAAP net income because it excludes items that are generally not directly related to the performance of the company’s core business operations and therefore provides supplemental information to Cadence’s management and investors regarding the performance of the business operations, facilitates comparisons to the historical operating results and allows the review of Cadence’s business from the same perspective as Cadence’s management, including forecasting and budgeting.

The following tables reconcile the specific items excluded from GAAP net income and GAAP net income per diluted share in the calculation of non-GAAP net income and non-GAAP net income per diluted share for the periods shown below:

Cadence expects that its corporate representatives will meet privately during the quarter with investors, the media, investment analysts and others. At these meetings, Cadence may reiterate the business outlook published in this press release.

During the Quiet Period, the business outlook in these documents should be considered historical, speaking as of prior to the Quiet Period only and not subject to any update by the company. During the Quiet Period, Cadence’s representatives will not comment on Cadence’s business outlook, financial results or expectations. The Quiet Period will extend until the day when Cadence’s second quarter 2017 earnings release is published, which is currently scheduled for July 24, 2017.
