Fiscal Year 2026 Outlook

		Previous Guidance		Updated Guidance
Revenues		$1.805 billion - $1.850 billion		$1.825 billion - $1.867 billion
Year-over-Year Growth Rate		5.4% - 8.0%		6.5% - 9.0%
Non-GAAP Earnings Per Share		$10.11 - $10.39		$10.20 - $10.48
Year-over-Year Growth Rate		8.0% - 11.0%		9.0% - 12.0%

The Company is increasing its fiscal 2026 revenues and non-GAAP diluted earnings per share guidance, as indicated above. Actual revenues and non-GAAP diluted earnings per share could vary from this guidance due to factors discussed under “Forward-Looking Statements” or other factors.

The Company’s fiscal 2026 diluted earnings per share guidance is provided on a non-GAAP basis only. The Company does not provide a reconciliation of guidance for non-GAAP diluted EPS to GAAP diluted EPS (the most directly comparable GAAP measure) on a forward-looking basis because the Company is unable to provide a meaningful or accurate compilation of reconciling items and certain information is not available. This is due to the inherent difficulty and complexity in accurately forecasting the timing and amounts of various items included in the calculation of GAAP diluted EPS but excluded in the calculation of non-GAAP diluted EPS, such as acquisition costs and other non-recurring items that have not yet occurred, are out of the Company’s control or cannot otherwise reasonably be predicted. For the same reasons, the Company is unable to address the significance of unavailable information which may be material and therefore could result in GAAP diluted EPS being materially different from projected non-GAAP diluted EPS.

Presentation of Non-GAAP Financial Measures

This earnings release includes a presentation of non-GAAP net income, non-GAAP diluted earnings per share, non-GAAP operating income (loss) by segment and non-GAAP operating margin, all of which are non-GAAP financial measures. The presentation of these non-GAAP figures is provided to allow for the comparison of the underlying performance of the Company, excluding the impact of restructuring and other charges (including certain legal costs), amortization of intangible assets acquired through business acquisitions, and associated tax effects, and discrete income tax items. Although we exclude amortization of acquired intangible assets from our non-GAAP figures, revenue generated from such intangibles is included in determining non-GAAP financial performance of the Company. Management believes that the non-GAAP financial measures presented in this earnings release provide (i) enhanced insight into the ongoing operations of the Company, (ii) meaningful information regarding the Company’s financial results (excluding amounts management does not view as reflective of ongoing operating results) for purposes of planning, forecasting and assessing the performance of the Company’s businesses, (iii) a meaningful comparison of financial results of the current period against results of past periods and (iv) financial results that are generally more comparable to financial results of peer companies than are GAAP figures. Non-GAAP financial measures should not be assessed in isolation or as a substitute for measures of financial performance prepared in accordance with GAAP. Our non-GAAP measures may not be the same as measures used by other companies due to possible differences in methods and in the items or events for which adjustments are made.
