SCHAFFHAUSEN, Switzerland — January 31, 2012 — Tyco International Ltd. (NYSE: TYC) today reported $0.71 in diluted earnings per share (EPS) from continuing operations for the fiscal first quarter of 2012 and diluted EPS from continuing operations before special items of $0.84 per share. Revenue in the quarter of $4.2 billion increased 4% versus the prior year excluding the Electrical & Metal Products business, which is now reported as an equity investment, and organic revenue also grew 4%.

Tyco Chairman and Chief Executive Officer Ed Breen said, “We delivered a strong quarter operationally with continued organic revenue growth supported by improving order activity. The year over year improvement in our operating margin reflects increased volume in our product businesses, a higher mix of service revenue and the benefits of our cost containment and restructuring actions. This helped us deliver another quarter of double digit increases in earnings per share.”

“We are making good progress with our plan to separate Tyco into three standalone public companies and we remain on track to complete the proposed transaction by the end of our fiscal fourth quarter,” Breen added.

Organic revenue, free cash flow and operating income, operating margin, income and diluted EPS from continuing operations before special items are non-GAAP financial measures and are described below. For a reconciliation of these non-GAAP measures, see the attached tables. Additional schedules as well as First Quarter Review slides can be found at www.tyco.com on the Investor Relations portion of Tyco’s website.

SEGMENT RESULTS

The financial results presented in the tables below are in accordance with GAAP unless otherwise indicated. All dollar amounts are pre-tax and stated in millions. All comparisons are to the fiscal first quarter of 2011 unless otherwise indicated.

Security Solutions

Revenue of $2.2 billion increased 2% in the quarter with organic revenue growth of 3%. Recurring revenue grew 4% organically with growth in all geographic regions. Non-recurring revenue grew 1% with strong growth in Asia Pacific and Latin America partially offset by modest declines in the North America and EMEA regions.

Operating income was $339 million and the operating margin was 15.7%. Special items of $36 million primarily consisted of separation-related impairment and restructuring charges. Operating income before special items was $375 million and the operating margin improved 70 basis points to 17.4%. The increase in operating margin resulted from faster growth in ADT’s higher margin recurring revenue business and the continued benefit of restructuring and cost reduction activities.

Fire Protection

Revenue of $1.1 billion increased 3% in the quarter with organic revenue growth of 2%. Organic revenue growth of 8% in fire products and 2% in service partially was offset by a 5% organic revenue decline in systems installation due to continued softness in the non-residential construction market. Excluding the impact of foreign currency, orders increased 6% year-over-year and backlog increased 4% to $1.2 billion on a quarter sequential basis.

Operating income was $144 million and the operating margin was 12.7%. Operating income before special items was $147 million and the operating margin was 13.0%. The 140 basis point margin improvement was driven by increased volume in products and a higher mix of service revenue as well as the continued benefit of cost-containment and restructuring actions.

Flow Control

Revenue of $923 million increased 12% in the quarter with organic revenue growth of 10%. Organic revenue growth of 13% in Valves and 28% in Thermal Controls was partially offset by an organic revenue decline of 15% in the Water business. Excluding the impact of foreign currency, orders increased 16% year-over-year and backlog increased 4% to $1.8 billion on a quarter sequential basis.

Operating income was $114 million and the operating margin was 12.4%. Operating income before special items of $113 million benefited from increased volume driven by the Valves business.

OTHER ITEMS

·                  Cash from operating activities was $338 million and free cash flow was negative $36 million, which included a cash outflow of $49 million primarily related to separation and restructuring activities. The company completed the quarter with $1.0 billion in cash and cash equivalents.

·                  Corporate expense excluding special items was $86 million.

·                  The company incurred pre-tax charges of $77 million in the quarter primarily related to separation and restructuring activities.

·                  The tax rate before special items was 19.4%.

·                  During the first quarter and through January 30, 2012, the company has repurchased 6.8 million shares for $300 million.

·                  On December 6, 2011, Tyco completed the acquisition of Visonic Ltd., a global developer and manufacturer of electronic security systems and components, for approximately $100 million in cash. Visonic is a leader in advanced wireless technology for the security industry with technologies in use in more than 1 million wireless installations around the world.

NON-GAAP MEASURES

Organic revenue, free cash flow (outflow) (FCF), and income from continuing operations, earnings per share (EPS) from continuing operations, operating income, operating margin and corporate expense, in each case “before special items,” are non-GAAP measures and should not be considered replacements for GAAP results.

Organic revenue is a useful measure used by the company to measure the underlying results and trends in the business. The difference between reported net revenue (the most comparable GAAP measure) and organic revenue (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). Effective the first quarter of fiscal 2011, the Company’s organic growth / decline calculations incorporate an estimate of prior year reported revenue associated with acquired entities that have been fully integrated within the first year (such as Broadview Security), and exclude prior year revenues associated with entities that do not meet the criteria for discontinued operations which have been divested within the past year. The rate of organic growth or decline is calculated based on the adjusted number to better reflect the rate of growth or decline of the combined business, in the case of acquisitions, or the remaining business, in the case of dispositions. The rate of organic growth or decline for acquired businesses that are not fully integrated within the first year will continue

5

to be based on unadjusted historical revenue. Organic revenue and the rate of organic growth or decline as presented herein may not be comparable to similarly titled measures reported by other companies.

Organic revenue 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 results of the company’s businesses, such as acquisitions and divestitures. It may be used as 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 in combination with the GAAP numbers. See the accompanying tables to this press release for the reconciliation presenting the components of organic revenue.

FCF is a useful measure of the company’s cash which is free from any significant existing obligation. The difference between Cash Flows from Operating Activities (the most comparable GAAP measure) and FCF (the non-GAAP measure) consists mainly of significant cash flows 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, or a measure that is based on it, may be used as a component in the company’s incentive compensation plans. The difference reflects the impact from:

·                  net capital expenditures,

·                  accounts purchased by ADT,

·                  cash paid for purchase accounting and holdback liabilities,

·                  voluntary pension contributions, and

·                  the sale of accounts receivable programs.

Capital expenditures and accounts purchased by ADT are subtracted because they represent long-term commitments. Cash paid for purchase accounting and holdback liabilities is subtracted because these cash outflows are not available for general corporate uses. Voluntary pension contributions and the impact from the sale of accounts receivable programs are added or subtracted because this activity is driven by economic financing decisions rather than operating activity.

The limitation associated with using FCF is that it adjusts for cash items that are ultimately within management’s and the Board of Directors’ discretion to direct and 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. 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 company has presented its income and EPS from continuing operations, operating income and margin, and its corporate expense before special items. Special items include charges and gains related to divestitures, acquisitions, restructurings, impairments, legacy legal and tax

6

charges and other income or charges that may mask the underlying operating results and/or business trends of the company or business segment, as applicable. The company utilizes these measures to assess overall operating performance and segment level core operating performance, as well as to provide insight to management in evaluating overall and segment operating plan execution and underlying market conditions. The Company also presents its effective tax rate as adjusted for special items for consistency. One or more of these measures may be used as components in the company’s incentive compensation plans. These measures are useful for investors because they may permit more meaningful comparisons of the company’s underlying operating results and business trends between periods. The difference between income and EPS from continuing operations before special items and income and EPS from continuing operations (the most comparable GAAP measures) consists of the impact of the special items noted above on the applicable GAAP measure. Operating income and margin before special items do not reflect any additional adjustments that are not reflected in income from continuing operations before special items. The limitation of these measures is that they exclude the impact (which may be material) of items that increase or decrease the company’s reported operating income and margin and operating income and EPS from continuing operations. This limitation is best addressed by using the non-GAAP measures in combination with the most comparable GAAP measures in order to better understand the amounts, character and impact of any increase or decrease on reported results. Tyco provides general corporate services to its segments and those costs are reported in the “Corporate and Other” segment. This segment’s operating income (loss) is presented as “Corporate Expense.”
