Comment and Outlook

Frank Laukien, Bruker’s President and CEO, commented: “We are pleased with our first quarter 2011 results, as we delivered solid growth in revenue, adjusted operating margins and earnings year-over-year.  Overall our end markets are healthy, and with our 2010 and recent new product introductions and strategic acquisitions, we have further diversified our end markets.  As a result, our first quarter 2011 new order bookings have increased by more than 40% over the first quarter of 2010, and we ended the first quarter of 2011 with a new record in backlog.  Bruker is very well positioned to continue executing its strategy of rapid, profitable growth and high return on invested capital.”

Brian Monahan, Chief Financial Officer of Bruker Corporation, added: “During the first quarter of 2011, we accelerated our strategic investments in research and development, as well as in marketing and sales for our new Chemical & Applied Markets (CAM) division.  These investments were predominantly in countries where we were not able to tax-benefit these losses, putting pressure on our first quarter 2011 tax rate.  The high GAAP tax rate, combined with foreign exchange losses, negatively affected our EPS by approximately $0.03 in the first quarter of 2011.  As a result of our strong revenue, bookings and adjusted operating income momentum, and expected improved tax rate for the remainder of 2011, we confirm our financial goals for the full year 2011.”

Use of Non-GAAP Financial Measures

In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including adjusted EPS, adjusted operating income and adjusted operating margin, which exclude acquisition-related and restructuring and other charges. We exclude the above items because they are outside our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods. We believe that the use of non-GAAP measures helps investors to gain a better understanding of our core operating results and future prospects, consistent with how management measures and forecasts the company’s performance, especially when comparing such results to previous periods or forecasts.

For example:

We exclude certain acquisition-related charges or credits and associated tax effects, including charges for the sale of inventories revalued at the date of acquisition, significant transaction costs such as legal fees and credits associated with bargain purchases. We exclude these costs because we do not believe they are indicative of our normal operating costs.

We exclude charges and tax effects associated with restructuring and business divestiture activities, such as reducing overhead and consolidating facilities. We believe that the costs related to these restructuring and business divestiture activities are not indicative of our normal operating costs.

We exclude the expense and tax effects associated with the amortization of acquisition-related intangible assets because a significant portion of the purchase price for acquisitions may be allocated to intangible assets that have lives of 3 to 10 years.  We also exclude charges for non-cash stock-based compensation.  Exclusion of these non-cash expenses allows comparisons of operating results that are consistent over time for both our newly acquired and long-held businesses.

We exclude certain gains/losses associated with significant tax audits or events which cannot be expected to occur with regularity or predictability and that we believe are not indicative of typical gains and losses.

Bruker’s management uses these non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring the company’s core operating performance and comparing such performance to that of prior periods and to the performance of our competitors.  Such measures are also used by management in their financial and operating decision-making and for compensation purposes.

The non-GAAP financial measures of Bruker’s results of operations included in this press release are not meant to be considered superior to or a substitute for Bruker’s results of operations prepared in accordance with GAAP.  Reconciliations of such non-GAAP financial measures to the most directly comparable GAAP financial measures are set forth in the accompanying tables.
