Segment Data

Segment data reflects the results of Trimble's reportable segments under its management reporting system. Segment revenue and operating income are consistent with the respective non-GAAP measures discussed below and in the attached supplemental schedules.

Use of Non-GAAP Financial Information

In addition to financial information prepared in accordance with GAAP, this press release also contains certain non-GAAP financial measures based upon management's view of performance, including:

• Non-GAAP revenue
• Non-GAAP operating income
• Non-GAAP operating margin
• Non-GAAP net income
• Diluted non-GAAP earnings per share
• Non-GAAP tax rate

Beginning in the third quarter of 2018, the Company started reporting a non-GAAP revenue measure. Trimble believes this measure helps investors understand the performance of the business as non-GAAP revenue excludes the effects of certain acquired deferred revenue that was written down to fair value in purchase accounting. Management believes that excluding fair value purchase accounting adjustments more closely correlates with the ordinary and ongoing course of the acquired company's operations and facilitates analysis of revenue growth and business trends.  Prior periods have also been restated to reflect this non-GAAP measure.

Investors are encouraged to review 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, which can be found at the end of this press release. Additional financial information about Trimble's use of non-GAAP results can be found on the investor relations page of Trimble's website at:  http://investor.trimble.com.

These statements include expectations for future financial market and economic conditions, whether the positive trend in financial results will continue in 2019, the impact of acquisitions, the ability to achieve long-term business model targets, including the respect to organic growth, software growth and target net working capital and capex expectations for future R&D spend, the ability to deliver revenue, earnings per share and other financial projections that Trimble has guided for the first quarter of 2019 and beyond, 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, and our long-term growth targets and operating margins. 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. For example, Trimble's expected tax rate is based on current tax law, including current interpretations of the Tax Cuts and Jobs Act of 2017 ("TCJA"), and current expected income 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 Company's results may be adversely affected if the Company is unable to market, manufacture and ship new products, obtain new customers, or effectively integrate new acquisitions, including our recent acquisition of Viewpoint. The Company's results would also be negatively impacted by adverse geopolitical developments, weakening in the macro environment, foreign exchange fluctuations, critical part supply chain shortages, 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.
