FIRST QUARTER 2011 RESULTS

Almelo, the Netherlands – April 21, 2011—Sensata Technologies Holding N.V. (NYSE: ST) (the “Company”) announces results of its operations for the first quarter ended March 31, 2011.

Highlights of the First Quarter ended March 31, 2011

First quarter 2011 net revenue was $444.2 million, an increase of $67.1 million, or 17.8%, from the first quarter 2010 net revenue of $377.1 million. Excluding the impact of our recent acquisition, net revenue grew by 11%. First quarter 2011 net (loss) was $(9.5) million, or $(0.05) per diluted share, versus net income of $27.3 million or $0.17 per diluted share for the first quarter of 2010. First quarter Adjusted net income¹ was $91.1 million, or $0.50 per diluted share, which was 20.5% of net revenue, versus the first quarter 2010 Adjusted net income¹ of $69.2 million, or $0.44 per diluted share, which was 18.3% of net revenue.

Tom Wroe, Chairman and Chief Executive Officer, said, “We are pleased with our results and continue to deliver on our promises. Our core growth rate, amplified by our recent acquisition, resulted in 17.8% growth compared to the first quarter of the prior year. The effects of the events in Japan are expected to impact our second quarter revenue by about $25 million, which we have reflected in our guidance.”

The Company spent $25.2 million, or 5.7% of net revenue, on research, development and engineering related costs in the first quarter of 2011. These costs reside in both the Cost of revenue and the Research and development lines of the Condensed Consolidated Statements of Operations.

The Company’s ending cash balance at March 31, 2011 was $419.3 million. During the first quarter, the Company generated cash of $81.9 million from operations, used cash of $158.3 million in investing activities and generated cash of $2.1 million from financing activities. Included in the cash used in investing activities was $136.9 million, net of cash acquired, used for the acquisition of the Honeywell Automotive on Board business which closed on January 28, 2011.

The Company’s cash conversion cycle, which is defined as days sales outstanding (DSO) plus days on hand inventory (DOH) less days payable outstanding (DPO), was 45.7 days at the end of the first quarter compared to 49.3 days at December 31, 2010.

The Company recorded an income tax provision of $24.6 million for the first quarter 2011. Approximately $6.2 million of the provision, or 6.8% of Adjusted net income¹, related to taxes that are payable in cash and approximately $18.3 million related to deferred and other income tax expense.

The Company’s indebtedness at March 31, 2011 was $1.9 billion. The Company’s net debt² was $1.5 billion resulting in a leverage ratio of 3.1x. As of March 31, 2011, the Company was in compliance with all of its financial ratios and reporting covenants included in its debt agreements related to its primary operating subsidiary, Sensata Technologies B.V.

Jeff Cote, Chief Administrative and Financial Officer, said “Our profitability, cash generation and leverage levels are in line with or slightly ahead of our expectations. The integration of our most recent acquisition is off to a great start and we continue to believe we can achieve or exceed our investment case which will drive a strong return for shareholders.” Mr. Cote added, “Our GAAP loss for the first quarter of 2011 was driven primarily by a foreign currency loss recorded on our Euro denominated debt.”

Guidance

The Company anticipates net revenue of $440 to $460 million for the second quarter 2011, which represents growth of 18 to 24% over the second quarter 2010 net revenue of $391.8 million, adjusted for approximately $20 million of inventory replenishment which occurred during the second quarter of 2010. The Company expects that the events in Japan and the impact of those events around the world will reduce its second quarter revenue by approximately $25 million. This amount is factored into the Company’s guidance. The Company also expects to achieve net income of $37 to $43 million, or earnings per share calculated in accordance with generally accepted accounting principles (“GAAP”) of $0.21 - $0.24 per diluted share in the second quarter of 2011. In addition, the Company expects Adjusted net income¹ of $90 million to $96 million, or $0.50 - $0.53 per diluted share, for the second quarter 2011. This guidance assumes a share count of 181.3 million for the second quarter of 2011.

For the full year 2011, the Company continues to anticipate net revenue of $1.81 to $1.86 billion which represents 21 to 25% growth over the full year 2010 net revenue of $1.54 billion, after adjusting for approximately $50 million of inventory replenishment which occurred during the first half of 2010. The Company also expects to achieve earnings per diluted share calculated in accordance with GAAP of $0.59 to $0.69 for the full year 2011. In addition, the Company continues to expect Adjusted net income¹ of $368 million to $386 million, or $2.03 to $2.13 per diluted share for the full year 2011. This guidance assumes a share count of 181.4 million for the full year of 2011.

The earnings per share guidance in accordance with U.S. GAAP excludes any future potential gain or loss resulting from the movement of the Euro to U.S. dollar exchange rate and the impact on our Euro denominated debt.

¹See Non-GAAP Measures for discussion of Adjusted net income which includes a reconciliation of this measure to Net (loss) / income.

²Net debt represents total indebtedness including capital lease and other financing obligations, less cash and cash equivalents. The leverage ratio represents net debt divided by Adjusted EBITDA for the last twelve months.

Non-GAAP Measures

Adjusted net income is a non-GAAP financial measure. The Company defines Adjusted net income as follows: net (loss) / income before costs related to our initial public offering, currency translation loss / (gain) on debt and other hedges, asset step-up and intangible asset depreciation and amortization expenses, deferred income tax and other tax expense, amortization of deferred financing costs and interest expense associated with uncertain tax positions, and other costs. The Company believes Adjusted net income provides investors with helpful information with respect to the performance of the Company’s operations and management uses Adjusted net income to evaluate its ongoing operations and for internal planning and forecasting purposes. Adjusted net income is not a measure of liquidity. See the tables below which reconciles Net (loss) / income to Adjusted net income and Projected GAAP earnings per share to Projected Adjusted net income per share.

The following (unaudited) table¹ reconciles the Company’s Net (loss) / income to Adjusted net income for the first quarters ended March 31, 2011 and 2010.

¹The Company has prepared the reconciliation of Net (loss) / income to Adjusted net income on a gross basis. The Company’s definition of Adjusted net income includes the current tax expense (benefit) that will be payable (realized) on the Company’s income tax return and excludes deferred income tax and other tax expense. The Company’s current tax provision included in Net (loss) / income and Adjusted net income will be the same and unaffected by the reconciling items. As the Company treats deferred income tax and other tax expense as an adjustment to compute Adjusted net income, the deferred income tax effect associated with the reconciling items would not change Adjusted net income for each period presented.

²The following table reconciles diluted shares in accordance with GAAP to diluted outstanding shares used in the calculation of Adjusted net income per share. The GAAP diluted outstanding shares number excludes certain shares due to their anti-dilutive nature given the net loss. The Company believes that including these shares in the diluted number for purposes of calculating Adjusted net income per share is more meaningful to investors.

The following (unaudited) table identifies where in the Condensed Consolidated Statement of Operations the adjustments to reconcile Net (loss) / income to Adjusted net income were recorded for the first quarters ended March 31, 2011 and 2010.

The following (unaudited) table reconciles the Company’s Projected GAAP earnings per share to projected Adjusted net income per share for the second quarter and full year of 2011:

*The Projected GAAP earnings per share guidance excludes any future potential gain or loss resulting from the movement of the Euro to U.S. dollar exchange rate and the impact on our Euro denominated debt.
