Approximately $392 million remains under the current share repurchase authorization as of the end of the first quarter. As previously announced, Trimble has temporarily suspended its stock buyback program.

“The strength of the first quarter reflects our improving competitive position and strong execution in every segment,” said Steven W. Berglund, Trimble’s president and chief executive officer. “Our strategic evolution, which is expected to accelerate with the recently announced Viewpoint and e-Builder acquisitions, will lead to higher value added solutions and higher revenue growth. These acquisitions are expected to be accretive to operating margins and cash flow in 2019.”

Forward Looking Guidance

Non-GAAP guidance excludes the amortization of intangibles of $42 million related to previous acquisitions, anticipated acquisition costs of $8 million, the anticipated impact of stock-based compensation expense of $15 million, and $2 million in anticipated restructuring charges. GAAP guidance assumes a tax rate of 15 percent and non-GAAP guidance assumes a tax rate of 19 percent. Both GAAP and non-GAAP earnings per share assume approximately 253 million shares outstanding.

New Accounting Standard

Trimble adopted a new accounting standard, ASC 606, starting with the first quarter of fiscal 2018, which primarily affects recognition of revenue and related costs of sales for software term licenses, custom professional services contracts, and contracts with non-standard terms and conditions. Trimble is utilizing the full retrospective method of transition, and prior periods presented here have been restated to reflect adoption of this new standard.

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. Additional financial information about Trimble’s use of non-GAAP results can be found on the investor relations page of our website at: http://investor.trimble.com.

Safe Harbor

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.

FOOTNOTES TO GAAP TO NON-GAAP RECONCILIATION

(Unaudited)

Our non-GAAP measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures. The non-GAAP financial measures included in the previous table as well as detailed explanations to the adjustments to comparable GAAP measures, are set forth below:

Non-GAAP gross margin

We believe our investors benefit by understanding our non-GAAP gross margin as a way of understanding how product mix, pricing decisions and manufacturing costs influence our business. Non-GAAP gross margin excludes restructuring charges, amortization of purchased intangible assets, stock-based compensation, amortization of acquisition-related inventory step-up, and acquisition/divestiture items associated with the acceleration of acquisition stock options from GAAP gross margin. We believe that these exclusions offer investors additional information that may be useful to view trends in our gross margin performance.

Non-GAAP operating expenses

We believe this measure is important to investors evaluating our non-GAAP spending in relation to revenue. Non-GAAP operating expenses exclude restructuring charges, amortization of purchased intangible assets, stock-based compensation, acquisition/divestiture items associated with external and incremental costs resulting directly from merger and acquisition activities such as legal, due diligence, integration, and other required closing costs including the acceleration of acquisition stock options from GAAP operating expenses. We believe that these exclusions offer investors supplemental information to facilitate comparison of our operating expenses to our prior results.

Non-GAAP operating income

We believe our investors benefit by understanding our non-GAAP operating income trends which are driven by revenue, gross margin, and spending. Non-GAAP operating income excludes restructuring charges, amortization of purchased intangible assets, stock-based compensation, amortization of acquisition-related inventory step-up, acquisition/divestiture items associated with external and incremental costs resulting directly from merger and acquisition activities such as legal, due diligence, integration, and other required closing costs including the acceleration of acquisition stock options. We believe that these exclusions offer an alternative means for our investors to evaluate current operating performance compared to results of other periods.

Non-GAAP non-operating income (expense), net

We believe this measure helps investors evaluate our non-operating income trends. Non-GAAP non-operating income (expense), net excludes acquisition/divestiture gains/losses associated with unusual acquisition related items such as intangible asset impairment charges, gains or losses related to the acquisitions, or sale of certain businesses and investments. We believe that these exclusions provide investors with a supplemental view of our ongoing financial results.

Non-GAAP income tax provision

We believe that providing investors with the non-GAAP income tax provision is beneficial because it provides for consistent treatment of the excluded items in our non-GAAP presentation.

Non-GAAP net income

This measure provides a supplemental view of net income trends which are driven by non-GAAP income before taxes and our non-GAAP tax rate. Non-GAAP net income excludes restructuring charges, amortization of purchased intangible assets, stock-based compensation, amortization of acquisition-related inventory step-up, acquisition/divestiture items, and non-GAAP tax adjustments from GAAP net income. We believe our investors benefit from understanding these exclusions and from an alternative view of our net income performance as compared to our past net income performance.

Non-GAAP diluted net income per share

We believe our investors benefit by understanding our non-GAAP operating performance as reflected in a per share calculation as a way of measuring non-GAAP operating performance by ownership in the company. Non-GAAP diluted net income per share excludes restructuring charges, amortization of purchased intangible assets, stock-based compensation, amortization of acquisition-related inventory step-up, acquisition/divestiture items, and non-GAAP tax adjustments from GAAP diluted net income per share. We believe that these exclusions offer investors a useful view of our diluted net income per share as compared to our past diluted net income per share.

These non-GAAP measures can be used to evaluate our historical and prospective financial performance, as well as our performance relative to competitors. We believe some of our investors track our “core operating performance” as a means of evaluating our performance in the ordinary, ongoing, and customary course of our 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 our core operating performance provides a supplemental way to provide consistency in period to period comparisons. Accordingly, management excludes from non-GAAP those items relating to restructuring charges, amortization of purchased intangible assets, stock-based compensation, amortization of acquisition-related inventory step-up, acquisition/divestiture items, and non-GAAP tax adjustments. For detailed explanations of the adjustments made to comparable GAAP measures, see items (A) - ( H ) below.
