Use of Non-GAAP Financial Information

To help investors understand Trimble's past financial performance and future results, as well as its performance relative to competitors, Trimble supplements the financial results that the company provides in accordance with generally accepted accounting principles, or GAAP, with non-GAAP financial measures. These non-GAAP measures can be used to evaluate Trimble's historical and prospective financial performance, as well as its performance relative to competitors. The company's management regularly uses supplemental non-GAAP financial measures internally to understand, manage and evaluate the business, and to make operating decisions. These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. Trimble believes that these non-GAAP financial measures reflect an additional way of viewing aspects of the company's operations that, when viewed with GAAP results, provide a more complete understanding of factors and trends affecting the business. Further, Trimble believes some of the company's investors track "core operating performance" as a means of evaluating performance in the ordinary, ongoing, and customary course of the company's operations. Core operating performance excludes items that are non-cash, not expected to recur or not reflective of ongoing financial results. Management also believes that looking at Trimble's core operating performance provides a supplemental way to provide consistency in period to period comparisons.

The specific non-GAAP measures, which Trimble uses along with a reconciliation to the nearest comparable GAAP measures and the explanation for why these non-GAAP measures provide useful information to investors regarding the financial condition and results of operations and why management chose to exclude selected items can be found at the end of this release. The method the company uses to produce non-GAAP results is not computed according to GAAP and may differ from the methods used by other companies. Trimble's non-GAAP results are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with Trimble's consolidated financial statements prepared in accordance with GAAP. Investors are encouraged to review the reconciliation of non-GAAP financial measures to the comparable GAAP results, which is attached to this earnings release.

Certain statements made in this press release are forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and are made pursuant to the safe harbor provisions of the Securities Litigation Reform Act of 1995. These statements include expectations for future financial market and economic conditions, the potential for growth and margin expansion in 2018, the ability to deliver revenue, earnings per share and other financial projections that Trimble has guided for the second quarter of 2018, including the expected tax rate, anticipated impact of stock-based compensation expense, amortization of intangibles related to previous acquisitions, anticipated acquisition costs, restructuring charges, the anticipated number of diluted shares outstanding, the planned Viewpoint acquisition and financing thereof, and the impact of the Viewpoint and e-Builder acquisitions on Trimble's financial results. These forward-looking statements are subject to change, and actual results may materially differ from those set forth in this press release due to certain risks and uncertainties. These factors include, for example, Trimble's expected tax rate and current expected income, which are based on current tax law, including current interpretations of the Tax Cuts and Jobs Act of 2017 ("TCJA"), and may be affected by evolving interpretations of TCJA; the jurisdictions in which profits are determined to be earned and taxed; changes in the estimates of credits, benefits and deductions; the resolution of issues arising from tax audits with various tax authorities, including payment of interest and penalties; and the ability to realize deferred tax assets; the ability to complete the Viewpoint acquisition on the anticipated schedule, or at all; the ability to obtain long-term financing for the Viewpoint acquisition on favorable terms, or at all; and synergies between Viewpoint and Trimble, and acquisition accounting for Viewpoint, including the impact of the reduction of deferred revenue, are estimated and may be materially different from actual results. The Company's results may be adversely affected if the Company is unable to market, manufacture and ship new products, obtain new customers, or integrate new acquisitions. The Company's results would also be negatively adverse geopolitical developments, weakening in the macro environment, foreign exchange fluctuations, or the imposition of barriers to international trade. Any failure to achieve predicted results could negatively impact the Company's revenues, cash flow from operations, and other financial results. The Company's financial results will also depend on a number of other factors and risks detailed from time to time in reports filed with the SEC, including its quarterly reports on Form 10-Q and its annual report on Form 10- K, such as changes in economic conditions, critical part supply chain shortages, and possible write-offs of goodwill. Undue reliance should not be placed on any forward-looking statement contained herein, especially in light of greater uncertainty than normal in the economy in general. These statements reflect the Company's position as of the date of this release. The Company expressly disclaims any undertaking to release publicly any updates or revisions to any statements to reflect any change in the Company's expectations or any change of events, conditions, or circumstances on which any such statement is based.
