Trimble Reports Third Quarter 2006 Revenue Growth of 25 Percent

          SUNNYVALE, Calif., Oct. 24 /PRNewswire-FirstCall/ -- Trimble (Nasdaq: TRMB) today announced results for its third quarter 2006, ended September 29, 2006.  Revenue for the third quarter of 2006 was $234.9 million, up 25 percent from revenue of $188.5 million in the third quarter of 2005.

          Operating income for the third quarter of 2006 was $36.3 million, up 10 percent from the third quarter of 2005.  For year-over-year comparisons it should be noted that third quarter 2006 operating income reflects a $3.0 million impact from stock-based compensation expense resulting from the adoption of FAS 123R.  Additionally, the net impact of transactions with the Caterpillar Trimble Control Technologies (CTCT) joint venture, which were included in non-operating results in 2005, reduced operating results by $4.7 million in the quarter.  In addition, amortization of purchased intangibles and purchased in-process research and development expense increased by $2.1 million versus the third quarter of 2005 due to acquisitions.  Adjusting for the above factors, operating income in the third quarter of 2006 was up 38 percent compared to the third quarter of 2005.

          Net income for the third quarter of 2006 was $25.3 million, up 25 percent when compared to net income of $20.2 million in the third quarter of 2005. Earnings per share for the third quarter of 2006 were $0.43, up approximately 23 percent compared to earnings per share of $0.35 in the third quarter of 2005. Earnings per share in the third quarter of 2006 were negatively impacted by approximately $0.03 due to the adoption of FAS 123R and by approximately $0.03 due to higher amortization of intangibles.

          Adjusting for the impact of FAS 123R and acquisition related expenses, non-GAAP net income for the third quarter of 2006 was $29.2 million, up 39 percent compared to non-GAAP net income of $21.0 million in the third quarter of fiscal 2005.  Non-GAAP earnings per share for the third quarter of 2006 were $0.50, up approximately 36 percent from non-GAAP earnings per share of $0.37 in the third quarter of 2005.  GAAP and non-GAAP earnings per share for the third quarter of 2006 were calculated on a diluted basis using approximately 58.5 million shares.

          “Our continued success reflects the combination of a robust strategy combined with effective execution.  All segments within Trimble contributed to the third quarter.  In particular, the Mobile Solutions segment continues to demonstrate rapid development with accompanying improvements in financial performance,” said Steven W. Berglund, Trimble’s president and chief executive officer.  “We believe Trimble should continue to exhibit solid performance in the fourth quarter of 2006 and into 2007.”

          Trimble Results by Business Segment

          For year-over-year comparisons it should be noted that third quarter 2005 results did not include stock-based compensation expense because FAS 123R was not adopted until the first quarter of 2006.

          Engineering and Construction

          Revenue for Engineering and Construction (E&C) was $162.4 million for the third quarter of 2006, up approximately 21 percent compared to revenue of $134.2 million in the third quarter of 2005.

          Operating margins in E&C were 24 percent in the third quarter of 2006, compared to 26 percent in the third quarter of 2005.  Excluding the impact of FAS 123R adoption and the CTCT joint venture transactions discussed above, E&C operating margins were 27 percent.

          Growth in E&C was driven by continued strength in end markets and strong sales across the E&C product line.

          Field Solutions

          Field Solutions (TFS) revenue was $29.2 million in the third quarter of 2006, up 18 percent compared to $24.9 million in revenue in the third quarter of 2005.  Growth was driven both by increased agricultural product sales and GIS product sales.

          TFS operating margins for the third quarter of 2006 were 19 percent, compared to 16 percent in the third quarter of 2005 due to strong operating leverage.

          Mobile Solutions

          Third quarter 2006 revenue for Mobile Solutions (TMS), was $16.4 million, up 128 percent from revenue of $7.2 million in the third quarter of 2005. Organic revenue growth was strong, while revenue from acquisitions began to contribute meaningfully to results.

          TMS operating margins were 7 percent for the third quarter of 2006, compared to a 10 percent loss in the third quarter of 2005.  Margin expansion came from increased operating leverage driven principally by higher subscription revenue.

          Advanced Devices

          Advanced Devices revenue was $26.8 million, up 21 percent from revenue of $22.2 million in the third quarter of 2005, due primarily to increased sales of embedded devices and Applanix products, and licensing revenue from Nokia.

          Advanced Devices operating margins were 15 percent, compared to 13 percent in the third quarter of 2005.

          Non-GAAP vs. GAAP Financials

          The Company provides non-GAAP financial measures including “non-GAAP net income,” “non-GAAP operating income,” and “non-GAAP earnings per share” to supplement its consolidated financial statements presented in accordance with GAAP. These non-GAAP financial measures are intended to supplement the user’s overall understanding of the Company’s current financial performance and its prospects for the future. In many cases, non-GAAP financial measures are used by analysts and investors to evaluate the Company.

          The Company excludes the amortization of purchased intangibles, in-process research and development, restructuring charges, and the impact of stock-based compensation in computing non-GAAP measures because the chief executive officer excludes these items when budgeting and evaluating the business. These non-GAAP financial measures are not intended to supersede or replace the Company’s GAAP results. Please see the supplemental financial statements, attached to this press release, for a reconciliation of GAAP to non-GAAP results.

          Forward Looking Guidance

          In the fourth quarter of 2006 the Company expects revenue to grow 18 to 20 percent compared to the fourth quarter of 2005, with revenue between $220 million and $225 million. At a 36 percent tax rate, with approximately 59.0 million shares outstanding, the Company expects fourth quarter 2006 GAAP earnings per share between $0.31 and $0.34.

          The above GAAP guidance includes stock-based compensation due to the adoption of FAS 123R. On a post-tax basis, the Company expects stock-based compensation for the fourth quarter of 2006 to be approximately $0.03 per share.

          The Company expects non-GAAP earnings per share between $0.40 and $0.43, compared to actual non-GAAP earnings per share of $0.29 in the fourth quarter of 2005. Non-GAAP guidance for the fourth quarter of 2006 uses a 36 percent tax-rate and excludes the amortization of intangibles of $5.6 million in the quarter, as well as the anticipated impact of stock-based compensation expense of $2.7 million.

          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 the revenue, effective tax rate, stock-based compensation, amortization of purchased intangibles and earnings per share estimates for the fourth fiscal quarter of 2006 and the Company’s belief that it will continue to exhibit solid performance in the fourth quarter and through 2007. 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, strong demand for the Company’s products may not continue because of a decline in the overall health of the economy and international markets, which may result in reduced capital spending. Fuel and other operating costs could remain high or increase, which could weaken sales into the agricultural market. In addition, the Company’s results may be adversely affected if the growth rates and profitability expectations for each of its four segments are not achieved, or its joint ventures and recent acquisitions do not achieve anticipated results, or if the Company is unable to market, manufacture and ship new products. Any failure to achieve predicted results could negatively impact the Company’s revenues, gross margin and other financial results. Whether the Company achieves its guidance for the fourth fiscal quarter of 2006 will also depend on a number of other factors, including the 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. Undue reliance should not be placed on any forward-looking statement, contained herein. 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.
