TYCO REPORTS FIRST QUARTER EARNINGS
FROM CONTINUING OPERATIONS OF $0.39 PER SHARE

PEMBROKE, Bermuda – Feb. 2, 2006 – Tyco International Ltd. (NYSE: TYC; BSX: TYC) today reported diluted GAAP earnings per share (EPS) from continuing operations of $0.39 for the first fiscal quarter of 2006, compared with $0.34 in the first fiscal quarter of 2005. EPS excluding special items was also $0.39. Results include $0.02 per share related to the expensing of stock options. Last year’s results included net charges of $0.07 per share related primarily to the early retirement of debt. Revenue in the quarter totaled $9.7 billion, with organic revenue growth of 4 percent. The company generated cash flow from operating activities of $675 million and free cash flow of $230 million in the quarter, including approximately $120 million in cash payments for previously disclosed legal items.

Tyco Chairman and Chief Executive Officer Ed Breen commented, “On an overall basis, we delivered good organic growth; however, we are not satisfied with our operating performance this quarter, and we are focused on addressing the issues that arose in several areas. We are confident that we are taking the right actions and expect to make meaningful progress throughout the remainder of the year.”

During the current quarter, Tyco adopted Statement of Financial Accounting Standards (SFAS) No. 123R, which requires the expensing of stock options and prior year results were not restated. Organic revenue growth, free cash flow, operating income before stock option

expense, and net debt are non-GAAP financial measures and are described below. For a reconciliation of these non-GAAP measures, see the attached tables.

SEGMENT RESULTS

The financial results presented in the tables below are in accordance with GAAP unless otherwise indicated. All dollar amounts are pretax and stated in millions. All comparisons are to the quarter ended December 31, 2004 unless otherwise indicated.

Electronics

	Dec. 30, 2005			Dec. 31, 2004			$ Change			% Change
Revenue	$	3,022		$	2,879		$	143		5	%
Operating Income Before Stock Option Expense	$	395		$	414		$	(19	)	(5	)%

Stock Option Expense	$	(11	)	$	0		$	(11	)
Operating Income	$	384		$	414		$	(30	)	(7	)%
Operating Margin	12.7		%	14.4		%

Organic revenue growth was 8 percent. Organic revenue growth in connector and cable assembly products was 11 percent. Growth was strong in the communications, computer and consumer electronics, general industrial and energy markets. Organic revenue growth in Automotive was 6 percent, with growth in Asia and North America partially offset by flat revenue in Europe. Orders were up 13 percent organically, which resulted in a book-to-bill ratio of 1.02.

Operating income decreased by $30 million. Income from higher revenue was more than offset by approximately $40 million in increased materials costs, $6 million in incremental costs for restructuring, and $11 million for stock option expense.

Fire & Security

	Dec. 30, 2005			Dec. 31, 2004			$ Change			% Change
Revenue	$	2,793		$	2,882		$	(89	)	(3	)%
Operating Income Before Stock Option Expense	$	239		$	283		$	(44	)	(16	)%

Stock Option Expense	$	(11	)	$	0		$	(11	)
Operating Income	$	228		$	283		$	(55	)	(19	)%
Operating Margin	8.2		%	9.8		%

Organic revenue growth was 1 percent with moderate growth in residential security and the Worldwide Fire Services business partially offset by weakness in the commercial security business.

Operating income decreased by $55 million. The operating income decline was primarily due to a $23 million decrease in commercial security as a result of lower revenue and higher installation costs, as well as a $13 million decline in the Worldwide Fire Services business due to lower contracting margins. Income was also reduced by $11 million for stock option expense.

Healthcare

	Dec. 30, 2005			Dec. 31, 2004				$ Change		% Change
Revenue	$	2,287		$	2,319		$	(32	)	(1	)%
Operating Income Before Stock Option Expense	$	551		$	581		$	(30	)	(5	)%

Stock Option Expense	$	(12	)	$	0		$	(12	)
Operating Income	$	539		$	581		$	(42	)	(7	)%
Operating Margin	23.6		%	25.1		%

Organic revenue growth was 1 percent. Growth in International and Surgical was offset by revenue declines in Imaging, Respiratory and Medical. The revenue declines in Imaging and Respiratory were primarily due to the impact of several voluntary product recalls.

Operating income decreased by $42 million. Operating income was adversely impacted by $31 million due to costs related to product recalls and increased compliance-related costs, a $20 million decline due to continued weakness in Retail, and $12 million related to stock option

expense. In addition, the company invested an incremental $24 million in research and development and sales and marketing over the same quarter a year ago.

Engineered Products & Services

	Dec. 30, 2005			Dec. 31, 2004			$ Change			% Change
Revenue	$	1,604		$	1,513		$	91		6	%
Operating Income Before Stock Option Expense	$	174		$	172		$	2		1	%

Stock Option Expense	$	(5	)	$	0		$	(5	)
Operating Income	$	169		$	172		$	(3	)	(2	)%
Operating Margin	10.5		%	11.4		%

Organic revenue growth was 8 percent. Three of the four businesses had combined organic revenue growth of 11 percent, which was partially offset by a slight revenue decline at Infrastructure Services as a result of a strategic decision to be more selective in bidding for new projects.

Operating income decreased by $3 million. Income from higher revenue was offset by approximately $35 million from reduced steel spreads and $5 million related to stock option expense.

DISCONTINUED OPERATIONS

During the quarter, Tyco announced that it had reached a definitive agreement to sell its Plastics, Adhesives and Ludlow Coated Products businesses for $975 million. The transaction is expected to close in Tyco’s second fiscal quarter. The $237 million after-tax loss from discontinued operations included a $256 million after-tax impairment charge.

OUTLOOK

For the second quarter of 2006, the company expects to achieve EPS from continuing operations excluding special items of $0.40 to $0.42 per share. Tyco expects similar top-line growth and operating margins compared with the first quarter due to continued costs related to voluntary product recalls and regulatory compliance efforts in Healthcare and continued lower contracting margins in Fire & Security.

The company continues to expect full-year EPS from continuing operations excluding special items of $1.85 to $1.92 per share. The company further expects that 2006 free cash flow, excluding the cash impact of previously disclosed legal items, will exceed net income excluding special items. In the second quarter, the company expects to make cash payments of approximately $450 million for previously disclosed legal matters.

EPS from continuing operations excluding special items is a non-GAAP financial measure and is described below.

NON-GAAP MEASURES

“EPS from continuing operations excluding special items,” “free cash flow” (FCF), “organic revenue growth,” “operating income before stock option expense,” and “net debt” are non-GAAP measures and should not be considered replacements for GAAP results.

The company has forecast its EPS from continuing operations results excluding special items related to divestitures, early retirement of debt, transaction costs related to the separations, and other income or charges that may mask the underlying results and trends and make it difficult to give investors perspective on underlying business results. Because the company cannot predict the amount and timing of such items and the associated charges or gains that will be taken, it is difficult to include the impact of those items in the forecast.

The company has forecast its cash flow results excluding any voluntary pension contributions because it has not yet made a determination about the amount and timing of any future such contributions. In addition, the company’s forecast excludes the impact of special items because the company cannot predict the amount and timing of such items.

The difference between cash flows from operating activities (the most comparable GAAP measure) and FCF (the non-GAAP measure) consists mainly of significant cash outflows that the company believes are useful to identify. FCF permits management and investors to gain insight into the number that management employs to measure cash that is free from any significant existing obligation. It is also a significant component in the company’s incentive compensation plans. The difference reflects the impact from:

• the sale of accounts receivable programs,

• net capital expenditures,

• acquisition of customer accounts (ADT dealer program),

• cash paid for purchase accounting and holdback/earn-out liabilities and,

• voluntary pension contributions.

See the accompanying tables to this press release for a cash flow statement presented in accordance with GAAP and a reconciliation presenting the components of FCF.

The impact from the sale of accounts receivable programs and voluntary pension contributions is added or subtracted from the GAAP measure because this activity is driven by economic financing decisions rather than operating activity. Capital expenditures and the ADT dealer program are subtracted because they represent long-term commitments. Cash paid for purchase accounting and holdback/earn-out liabilities is subtracted from Cash Flow from Operating Activities because these cash outflows are not available for general corporate uses.

The limitation associated with using FCF is that it subtracts cash items that are ultimately within management’s and the Board of Directors’ discretion to direct and that therefore may imply that there is less or more cash that is available for the company’s programs than the most comparable GAAP measure. This limitation is best addressed by using FCF in combination with the GAAP cash flow numbers.

FCF as presented herein may not be comparable to similarly titled measures reported by other companies. The measure should be used in conjunction with other GAAP financial measures. Investors are urged to read the company’s financial statements as filed with the Securities and Exchange Commission, as well as the accompanying tables to this press release that show all the elements of the GAAP measures of Cash Flows from Operating Activities, Cash Flows from Investing Activities, Cash Flows from Financing Activities and a reconciliation of the company’s total cash and cash equivalents for the period.

“Organic revenue growth” is a useful measure used by the company to measure the underlying results and trends in the business. The difference between reported net revenue growth (the most comparable GAAP measure)

and organic revenue growth (the non-GAAP measure) consists of the impact from foreign currency, acquisitions and divestitures, and other changes that do not reflect the underlying results and trends (for example, revenue reclassifications and changes to the fiscal year).

Organic revenue growth is a useful measure of the company’s performance because it excludes items that: i) are not completely under management’s control, such as the impact of foreign currency exchange; or ii) do not reflect the underlying growth of the company, such as acquisition and divestiture activity, or revenue reclassification. It is also a component of the company’s compensation programs. The limitation of this measure is that it excludes items that have an impact on the company’s revenue. This limitation is best addressed by using organic revenue growth in combination with the GAAP numbers. See the accompanying tables to this press release for the reconciliation presenting the components of organic revenue growth.

“Operating income before stock option expense” is a financial measure used by the company to evaluate the underlying results and operating performance of the businesses. The difference between operating income (the most comparable GAAP measure) and operating income before stock option expense (the non-GAAP measure) reflects the impact of adopting SFAS 123R on the current period results. The limitation of this measure is that it excludes an item that impacts the company’s current period operating income. This limitation is best addressed by using this measure in combination with operating income (the most comparable GAAP measure) because operating income before stock option expense does not reflect the impact of adopting SFAS 123R and may be higher than operating income (the most comparable GAAP measure). Management believes operating income before stock option expense is a useful measure that allows investors to draw comparisons between operating results reported prior to adoption of SFAS 123R and the current period, which may mask underlying trends and make it difficult to give investors perspective on underlying business results.

Net debt is a non-GAAP measure and should not be considered a replacement for GAAP results. Net debt is total debt (the most comparable GAAP measure) minus cash and cash equivalents. Management believes net debt is an important measure of liquidity, which it uses as a tool to measure the company’s ability to meet its future debt obligations. Cash and cash equivalents are subtracted from the GAAP measure because they could be used to reduce our debt obligations. See the accompanying table to this press release for the reconciliation of net debt.

The limitation associated with using net debt is that it subtracts cash items and therefore may imply that there is less company debt than the most comparable GAAP measure indicates and may include certain cash items that are not readily available for repaying debt. This limitation is best addressed by using net debt in combination with total debt because net debt may be significantly lower than the GAAP measure. Net debt should be used in conjunction with other GAAP financial measures.
