“We had a solid second quarter, achieving 30.6% year-over-year revenue growth and hitting the top end of our revenue guidance. In the quarter, our service provider business regained momentum with a record number of new wins and network expansion by existing customers. Our strong position in the carrier Wi-Fi market was validated by Infonetics’ Global Service Provider survey published in Q2, which found Ruckus to be the second most installed Wi-Fi brand and the number one brand being evaluated for 2014 deployments,” said Selina Lo, President and Chief Executive Officer at Ruckus Wireless. “Furthermore, our enterprise business continued to perform, adding over 2,900 new end-customers in the quarter.”

Non-GAAP Financial Measures

To supplement our financial results presented in accordance with Generally Accepted Accounting Principles (GAAP), this press release and the accompanying tables and the related earnings conference call contain certain non-GAAP financial measures, including non-GAAP gross profit and gross margin, non-GAAP operating income and operating margin, non-GAAP net income, non-GAAP dilutive net income per share and non-GAAP diluted weighted-average shares outstanding. We also provide projected third quarter 2013 non-GAAP dilutive net income per share and non-GAAP diluted weighted-average shares outstanding. We believe these non-GAAP financial measures are helpful in understanding our past financial performance and future results. Our non-GAAP financial measures should not be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with our consolidated financial statements prepared in accordance with GAAP. Our management regularly uses our supplemental non-GAAP financial measures internally to understand and manage our business and forecast future periods. These non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies.

Our non-GAAP financial measures include adjustments based on the following items:

Stock-based compensation expenses: We have excluded the effect of stock-based compensation from our non-GAAP operating results. Although stock-based compensation is a key incentive offered to our employees, we continue to evaluate our business performance excluding stock-based compensation expenses. Stock-based compensation expenses will recur in future periods.

Employer payroll tax expense associated with stock-based compensation: We have excluded the employer payroll tax expense associated with stock-based compensation in order to provide a complete picture of the company’s recurring core business operating results. Stock-based compensation has been and will continue for the foreseeable future to be a significant recurring expense in the company’s business.

Amortization of intangible assets: We have excluded the effect of amortization of intangible assets from our non-GAAP operating results. Amortization of intangible assets is a non-cash expense, and it is not part of our core operations. Investors should note that the use of intangible assets contributed to revenues earned during the periods presented and will contribute to future period revenues as well.

Change in fair value of preferred stock warrants: We have excluded the effect of the expense resulting from the change in fair value of preferred stock warrants from our non-GAAP operating results. The change in fair value is a non-cash expense, and it is not part of our core operations. Upon completion of our IPO in November 2012, all preferred stock warrants converted to common stock warrants.

Our non-GAAP Financial Measures are described as follows:

Non-GAAP gross profit and gross margin—Non-GAAP gross profit is gross profit as reported on our condensed consolidated statements of operations, excluding the impact of stock-based compensation, employer payroll tax expense associated with stock-based compensation and intangible asset amortization expense. Non-GAAP gross margin is non-GAAP gross profit divided by net revenue.

Non-GAAP operating income and operating margin—Non-GAAP operating income is income from operations as reported on our condensed consolidated statements of operations, excluding the impact of stock-based compensation, employer payroll tax expense associated with stock-based compensation and intangible asset amortization expense. Non-GAAP operating margin is non-GAAP operating income divided by net revenue.

Non-GAAP net income and diluted income per share—Non-GAAP net income is net income as reported on our condensed consolidated statements of operations, excluding the impact of stock-based compensation, employer payroll tax expense associated with stock-based compensation, intangible asset amortization expense and the change in fair value of preferred stock warrants. Non-GAAP diluted income per share is non-GAAP net income divided by the non-GAAP weighted-average diluted shares outstanding. For periods presented prior to the company’s IPO, non-GAAP diluted weighted-average shares outstanding was computed to give effect to the conversion of all redeemable convertible preferred stock, as if conversion had occurred at the beginning of the period. Upon completion of our IPO in November 2012, all preferred stock converted to common stock.

For reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section of the accompanying tables titled, “Reconciliation of GAAP to Non-GAAP Financial Measures.”
