SCHAFFHAUSEN, Switzerland — January 29, 2013 — Tyco (NYSE: TYC) today reported $0.34 in GAAP diluted earnings per share (EPS) from continuing operations for the fiscal first quarter of 2013 and diluted EPS from continuing operations before special items of $0.40. Revenue in the quarter increased 5% versus the prior year to $2.6 billion including a 3% benefit from acquisitions. Organic revenue grew 1% in the quarter with 6% growth in products, 2% growth in service and a 3% decline in installation revenue.

Tyco Chief Executive Officer George Oliver said, “We’re off to a great start as the new Tyco, integrating our fire and security businesses and executing on our growth strategy. We had another very good quarter,

* Normalized first quarter 2012 results reflect pro forma adjustments to corporate and interest expense to reflect the impact of the separation, and include dis-synergy costs associated with the separation of the Company’s North American security operations, also as a result of the separation. See Non-GAAP reconciliations.

with a 5% increase in revenue, driven partly by our acquisition strategy, and an 11% increase in earnings per share before special items on a normalized basis.  I am especially pleased with the traction we are getting from our productivity and sourcing initiatives, and the positive impact we are seeing from our increased investments in research and development.  Overall, our performance in the first quarter is a solid beginning to fiscal 2013.”

Organic revenue, free cash flow, operating income, segment operating income, and diluted and normalized 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 2012 unless otherwise indicated.

North America Systems Installation & Services

Revenue of $976 million increased 1.5% in the quarter. Service revenue increased 1% and installation revenue was flat with the prior year, for total organic revenue growth of 1%. Backlog of $2.4 billion declined 3% on a quarter sequential basis, excluding the impact of foreign currency, in line with expectations and the previously announced project selectivity in commercial security.

Operating income for the quarter was $108 million and the operating margin was 11.1%. Special items of $12 million consisted primarily of separation charges. Operating income before special items was $120 million and the operating margin was 12.3%. The 110 basis point improvement in operating margin before special items was driven by a higher mix of service revenue, improved execution in installation, and accelerated productivity benefits. These benefits more than offset dis-synergy costs associated with the separation of the ADT residential security business from our commercial security business, Tyco Integrated Security.

Rest of World Systems Installation & Services

Revenue of $1.1 billion increased 3% in the quarter, primarily driven by acquisitions. Organic revenue was flat with 3% growth in service and a 5% decline in installation. Backlog of $2.6 billion increased 3% on a quarter sequential basis, excluding the impact of foreign currency.

Operating income for the quarter was $114 million and the operating margin was 10.5%. Special items of $7 million consisted primarily of restructuring charges. Operating income before special items was $121 million, and the operating margin was 11.1%. The benefit of higher margin service revenue was offset by growth investments.

Global Products

Revenue of $534 million increased 16% in the quarter, including a 9% benefit due to acquisitions. Organic revenue grew 6% with growth across all three product platforms.

Operating income for the quarter was $74 million and the operating margin was 13.9%. Special items of $3 million consisted primarily of restructuring charges. Operating income before special items was $77 million and the operating margin was 14.4%. The year-over-year margin decrease was primarily driven by a double digit increase in research and development and sales and marketing investments. Additionally, the operating margin was impacted by a $6 million environmental remediation charge and lower sales of higher margin products due to the timing of shipments.  We estimate that these two items impacted operating margin by approximately 200 basis points.

OTHER ITEMS

·                  Cash from operating activities was negative $39 million and free cash flow was negative $133 million, which included a cash outflow of $103 million primarily related to separation and restructuring activities. Adjusted free cash outflow for the quarter was $30 million. The Company completed the quarter with $501 million in cash and cash equivalents.

·                  Corporate expense before special items was $58 million for the quarter.

·                  The tax rate before special items was 17.4% for the quarter.

·                  On December 21, 2012 the Company announced that its Board of Directors recommended shareholders approve a dividend increase of approximately 7% from $0.60 to $0.64 per share at the Company’s annual general meeting of shareholders, to be held on March 6, 2013.

·                  The Company purchased 1.8 million shares for $50 million during the quarter, and the Company’s Board of Directors approved an additional $600 million in repurchase authority to the existing $150 million.

NON-GAAP MEASURES

Organic revenue, free cash flow (outflow) (FCF), and income from continuing operations, earnings per share (EPS) from continuing operations, operating income and segment operating income, and normalized EPS, 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 either do not reflect the underlying results and trends of the Company’s businesses or are not completely under management’s control. There are limitations associated with organic revenue, such as the fact that, as presented herein, the metric may not be comparable to similarly titled measures reported by other companies. These limitations are best addressed by using organic revenue in combination with the GAAP numbers. Organic revenue may be used as a component in the company’s incentive compensation plans.

FCF is a useful measure of the company’s cash that permits management and investors to gain insight into the number that management employs to measure cash that is free from any significant existing obligation and is available to service debt and make investments. 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. 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,

·                  dealer generated accounts and bulk accounts purchased,

·                  cash paid for purchase accounting and holdback liabilities, and

·                  voluntary pension contributions.

Capital expenditures and dealer generated and bulk accounts purchased are subtracted because they represent long-term investments that are required for normal business activities. Cash paid for purchase accounting and holdback liabilities is subtracted because these cash outflows are not available for general corporate uses. Voluntary pension contributions are added because this activity is driven by economic financing decisions rather than operating activity. In addition, from time to time the company may present adjusted free cash flow, which is free cash flow, adjusted to exclude the cash impact of the special items highlighted below. This number provides information to investors regarding the cash impact of certain items management believes are useful to identify, as described below.

The limitation associated with using these cash flow metrics is that they adjust 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. Furthermore, these non-GAAP metrics may not be comparable to similarly titled measures reported by other companies. These limitations are best addressed by using FCF in combination with the GAAP cash flow numbers.

The company has presented its income and EPS from continuing operations, operating income and segment operating income before special items. Special items include charges and gains related to divestitures, acquisitions, restructurings, impairments, certain changes to accounting methodologies, legacy legal and tax 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, and from time to time presents corporate expense excluding special items. 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. 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 GAAP metrics, and these non-GAAP metrics may not be comparable to similarly titled measures reported by other companies. These limitations are 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.

The company 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.” Segment Operating Income represents Tyco’s operating income excluding the Corporate and Other segment, and reflects the results of Tyco’s three operating segments. Segment Operating Income before special items reflects GAAP operating income adjusted for the special items noted in the paragraph above.

In order to provide more meaningful comparison of fiscal 2013 results to fiscal 2012 results, normalized EPS before special items is presented. Normalized EPS adjusts fiscal 2012 GAAP results by replacing the GAAP interest and corporate expenses reported for fiscal 2012 (on a pre-separation basis) with the interest and corporate expenses estimated to be incurred in fiscal 2013 (on a post-separation basis), and adding estimated dis-synergy costs related to the separation of the Company’s North American security business to fiscal 2012 results. Normalized EPS before special items further adjusts normalized EPS for the special items described above.
