“The macroeconomic environment represented a significant challenge for Trimble throughout 2009.  Although difficult, we saw improving stability in the second half of the year which provided us with the opportunity to demonstrate year-over-year progression in the fourth quarter,” said Steven W. Berglund, Trimble’s president and chief executive officer. “This reinforces our anticipation of meaningful revenue growth in 2010, with strong operating leverage providing the potential to grow earnings significantly faster than revenue.  Trimble employees have distinguished themselves in a historically unprecedented period by confronting the needs of the short term while continuing to develop the platform for future growth.  As a result, our fundamental long-term strategy and financial model remain intact and have not been impaired by the cost reductions taken during the recession,” concluded Berglund.

Trimble Results by Business Segment

Segment operating income is revenue less cost of goods sold and operating expenses, excluding general corporate expenses, restructuring expenses, amortization of intangibles, amortization of acquisition-related inventory step-up charges, non-recurring acquisition costs, and the impact of stock-based compensation expense.

Engineering and Construction (E&C)

Fourth quarter 2009 E&C revenue was $154.3 million, up approximately 8 percent as compared to the fourth quarter of 2008, largely due to stronger sales of both survey instruments and machine control products.

E&C revenue for the full year 2009 was $578.6 million, down approximately 22 percent as compared to 2008 due to recessionary conditions, concentrated in the U.S. and Europe.

Operating income in E&C for the fourth quarter 2009 was $15.5 million, or 10.0 percent of revenue, as compared to $2.3 million, or 1.6 percent of revenue, in the fourth quarter of 2008.  Non-GAAP operating income was $17.5 million, or 11.3 percent of revenue, as compared to $3.9 million, or 2.7 percent of revenue, in the fourth quarter of 2008. The improvement in non-GAAP operating margin was primarily due to year-over-year cost reductions as a result of restructuring in the segment, as well as increased revenue.

The decline in non-GAAP operating margin was primarily due to lower revenue.

Field Solutions full year 2009 revenue was $291.8 million, down approximately 3 percent as compared to 2008.

Mobile Solutions

Fourth quarter 2009 Mobile Solutions revenue was $38.0 million, down approximately 5 percent as compared to the fourth quarter of 2008 primarily due to churn among smaller accounts that were impacted by the economic environment throughout the year.

For the full year 2009 Mobile Solutions revenue was $154.9 million, down approximately 7 percent as compared to 2008 primarily due to reduced sales of ready mix products for construction.

Operating income in Mobile Solutions for the fourth quarter 2009 was $4.2 million, or 11.0 percent of revenue, as compared to $3.3 million, or 8.3 percent of revenue, in the fourth quarter of 2008.  Non-GAAP operating income in Mobile Solutions was $5.2 million, or 13.7 percent of revenue, as compared to $4.5 million or 11.2 percent of revenue, in the fourth quarter of 2008 due to cost reductions.

Full year 2009 Advanced Devices revenue was $101.0 million, down approximately 16 percent as compared to 2008 due to reduced sales of embedded and aerial survey products.

Use of Non-GAAP Financial Information

To help our readers understand our past financial performance and our future results, we supplement the financial results that we provide in accordance with generally accepted accounting principles, or GAAP, with non-GAAP financial measures. The specific non-GAAP measures which we use along with a reconciliation to the nearest comparable GAAP measures and the explanation for why management chose to exclude selected items and the additional purposes for which these non-GAAP measures are used can be found at the end of this release. The method we use to produce non-GAAP results is not computed according to GAAP and may differ from the methods used by other companies. Our 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 our consolidated financial statements prepared in accordance with GAAP. Our management regularly uses our supplemental non-GAAP financial measures internally to understand, manage and evaluate our business, and to make operating decisions. These non-GAAP measures are among the primary factors management uses in planning for and forecasting future periods. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. Management generally compensates for the limitations in the use of non-GAAP financial measures by relying on comparable GAAP financial measures and providing investors with a reconciliation of the non-GAAP financial measure to the most directly comparable GAAP financial measure or measures. Investors are encouraged to review the reconciliation of our non-GAAP financial measures to the comparable GAAP results, which is attached to this earnings release.  Additional financial information about our use of non-GAAP results can be found on the investor relations page of our Web site at http://investor.trimble.com.

Non-GAAP guidance for the first quarter of 2010 excludes the amortization of intangibles of $14.0 million related to previous acquisitions and the anticipated impact of stock-based compensation expense of $4.9 million.

FOOTNOTES TO GAAP TO NON-GAAP RECONCILIATION

(Dollars in thousands)

(Unaudited)

The non-GAAP financial measures included in the previous table are non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP net income, non-GAAP diluted net income per share and operating leverage, and non-GAAP segment operating income before corporate allocations.    These non-GAAP measures can be used to evaluate the Company's historical and prospective financial performance, as well as its performance relative to competitors.  The Company believes some of its investors track the Company's "core operating performance" as a means of evaluating the Company's performance in the ordinary, ongoing, and customary course of its operations.  Management also believes that looking at its 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, amortization of purchased intangibles, stock based compensation, amortization of acquisition-related inventory step-up and non-recurring acquisition costs, which the Company believes are not indicative of its core operating performance.

( A ) Restructuring. Included in our GAAP presentation of cost of sales and operating expenses, restructuring costs recorded are primarily for employee compensation resulting from reductions in employee headcount in connection with our company restructurings.  We exclude restructuring from our non-GAAP measures because we believe they are not indicative of our core operating performance.

( B ) Amortization of purchased intangibles.  Included in our GAAP presentation of cost of sales and operating expenses, amortization of purchased intangibles recorded arise from prior acquisitions and are non-cash in nature.  We exclude these expenses from our non-GAAP measures because we believe they are not indicative of our core operating performance.

( C ) Stock-based compensation. Included in our GAAP presentation of cost of sales and operating expenses, stock-based compensation consists of expenses for employee stock options and awards and purchase rights under our employee stock purchase plan determined in accordance with SFAS 123(R).  We exclude stock-based compensation expense from our non-GAAP measures because some investors may view it as not reflective of our core operating performance as it is a non-cash expense.   For the three months and twelve months ended January 1, 2010 and January 2, 2009, stock-based compensation was allocated as follows:

	Three Months Ended				Twelve Months Ended
	Jan-1,		Jan-2,		Jan-1,		Jan-2,
	2010		2009		2010		2009
Cost of sales	$	486	$	487	$	1,854	$	1,920
Research and development		972		860		3,476		3,489
Sales and Marketing		1,246		1,095		4,446		3,993
General and administrative		2,634		2,121		8,883		6,764
	$	5,338	$	4,563	$	18,659	$	16,166

( D ) Amortization of acquisition-related inventory step-up. The purchase accounting entries associated with our business acquisitions require us to record inventory at its fair value, which is sometimes greater than the previous book value of the inventory. Included in our GAAP presentation of cost of sales, the increase in inventory value is amortized to cost of sales over the period that the related product is sold. We exclude inventory step-up amortization from our non-GAAP measures because we do not believe it is indicative of our core operating performance.

( E ) Non-recurring acquisition costs. Included in our GAAP presentation of operating expenses and non-operating income, net, non-recurring acquisition costs consist of external and incremental costs resulting directly from merger and acquisition activities such as legal, due diligence and integration costs. Also included are unusual acquisition related items such as a gain on bargain purchase (resulting from the fair value of indentifiable net assets acquired exceeding the consideration transferred) and payments made to settle earnout and holdback disputes. We exclude these items because they are non-recurring and unique to specific acquisitions and are not indicative of our core operating performance.

( F ) Income tax effect on non-GAAP adjustments. This amount adjusts the provision for income taxes to reflect the effect of the non-GAAP adjustments on non-GAAP net income.

( G ) Stock-based Compensation. The amounts consist of expenses for employee stock options and awards and purchase rights under our employee stock purchase plan determined in accordance with SFAS 123(R). As referred to above we exclude stock-based compensation here because investors may view it as not reflective of our core operating performance. However, management does include stock-based compensation for budgeting and incentive plans as well as for reviewing internal financial reporting. We discuss our operating results by segment with and without stock-based compensation expense, as we believe it is useful to investors to understand the impact of the application of SFAS 123(R) to our results of operations. Stock-based compensation not allocated to the reportable segments was approximately $1,479K and $1,243K for the three months ended January 1, 2010 and January 2, 2009, respectively and $5,450K and $4,492K for the twelve months ended January 1, 2010 and January 2, 2009, respectively.
