Third Quarter Fiscal 2018 Earnings May 9, 2018 Exhibit 99.2

This presentation contains forward-looking statements that are subject to the safe harbors created under the Securities Act of 1933, as amended (the “Securities Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business, and can be identified by the fact that they do not relate strictly to historical or current facts. Such forward-looking statements may include words such as ”expect,” “anticipate,” “intend,” “believe,” “estimate,” “plan,” “target,” “strategy,” “continue,” “may,” “will,” “should,” variations of such words, or other words and terms of similar meaning. All forward-looking statements reflect our best judgment and are based on several factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Such factors include, but are not limited to, the risks as identified in the “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business” sections of our Annual Report on Form 10-K for the fiscal year ended June 24, 2017, and other risks as identified from time to time in our Securities and Exchange Commission reports. Forward-looking statements are based on information available to us on the date hereof, and we do not have, and expressly disclaim, any obligation to publicly release any updates or any changes in our expectations, or any change in events, conditions, or circumstances on which any forward-looking statement is based. Our actual results and the timing of certain events could differ materially from the forward-looking statements. These forward-looking statements do not reflect the potential impact of any mergers, acquisitions, or other business combinations that had not been completed as of the date of this presentation. Safe Harbor Statement

Non-GAAP Results •In evaluating our business, we consider and use non-GAAP net income, which we define as net income excluding share-based compensation, acquisition related costs, and certain other non-cash or recurring and non-recurring items we do not believe are indicative of our core operating performance as a supplemental measure of operating performance. •Non-GAAP net income is not a measurement of our financial performance under GAAP and should not be considered as an alternative to GAAP net income. We present non-GAAP net income because we consider it an important supplemental measure of our performance since it facilitates operating performance comparisons from period to period by eliminating potential differences in net income caused by the existence and timing of share-based compensation charges, acquisition related costs, and certain other non-cash or recurring and non-recurring items. •Non-GAAP net income has limitations as an analytical tool and should not be considered in isolation or as a substitute for our GAAP net income. The principal limitations of this measure are that it does not reflect our actual expenses and may thus have the effect of inflating our net income and net income per share as compared to our operating results reported under GAAP. •Please see our third quarter fiscal 2018 press release for additional discussion of our use of non-GAAP financial measures, and the tables attached to the end of this presentation for a complete reconciliation of GAAP to non-GAAP financial measures used in this presentation.
