Second Quarter 2016 Sales

The company reported net sales of $1.562 billion in the second quarter of 2016, an 11 percent increase compared to net sales of $1.410 billion in the second quarter of 2015. On a comparable constant currency basis, net sales increased by approximately 2 percent compared to the second quarter of 2015.

Commenting on the company’s financial results, St. Jude Medical President and Chief Executive Officer Michael T. Rousseau said, “We continued to build momentum during the second quarter by bringing innovative products to our global markets. The strong performance in international sales gives us confidence that where we have a full portfolio, we can deliver top-tier growth. One of the major highlights of our quarter was the announcement of our pending merger with Abbott. We continue to be confident and excited about the potential of our combined organization and the powerful impact we can have on delivering industry leading innovation to physicians and patients around the world.”

As previously announced, St. Jude Medical has changed its sales reporting to more closely align with how the company manages the business in five key areas: atrial fibrillation, heart failure, neuromodulation, cardiovascular and traditional cardiac rhythm management. For additional information please see the Form 8-K provided by the company on January 13, 2016.

Atrial Fibrillation (AF)

AF product sales for the second quarter totaled $324 million, a 13 percent increase both on a reported and constant currency basis compared to the prior year quarter. Second quarter results were driven by strong global TactiCath™ and FlexAbility™ ablation catheter sales.

Heart Failure (HF)

HF product sales, which include cardiac resynchronization therapy (CRT) products, HeartMate™ ventricular assist devices and the CardioMEMS™ HF System, totaled $384 million for the second quarter, a 48 percent increase compared to the prior year quarter, primarily due to incremental net sales associated with ventricular assist devices, acquired through our Thoratec acquisition. On a comparable constant currency basis, HF product sales decreased 1 percent compared to the prior year quarter. Second quarter results reflect strong global growth in ventricular assist devices, offset by the impact of U.S. CRM sales weakness on our CRT products.

Neuromodulation

St. Jude Medical sales of neuromodulation products were $140 million in the second quarter of 2016, a 19 percent increase on a reported basis and a 20 percent increase on a constant currency basis compared to the prior year quarter. Neuromodulation growth was driven by the St. Jude Medical Burst technology offering in international markets, U.S. launch of the Axium™ system as well as the introduction of the Infinity™ DBS system and directional lead in Europe.

Cardiovascular

Total cardiovascular sales were $319 million for the second quarter of 2016, an increase of 1 percent compared to the prior year quarter. On a constant currency basis, cardiovascular sales increased 2 percent compared to the prior year quarter. Cardiovascular growth was driven by the continued strength of the Portico™ Transcatheter Aortic Valve Implantation System in Europe and our PCI optimization strategy, which includes products such as OPTIS™ optical coherence tomography products and PressureWire™ fractional flow reserve technology.

Traditional Cardiac Rhythm Management (CRM)

Total CRM sales, which include single and dual chamber implantable cardioverter defibrillator (ICD) and pacemaker products, were $395 million for the second quarter of 2016, an 8 percent decline compared with the second quarter of 2015. After adjusting for the impact of foreign currency, traditional CRM sales decreased 7 percent. Global results continue to be impacted by lower sales in the United States, partially offset by continued adoption of our MRI conditional product portfolio in countries where they are offered.

Second Quarter Earnings Results

In the second quarter the company recognized net after-tax charges of $67 million, or $0.23 per diluted share, primarily related to amortization of intangible assets and acquisition-related costs. Including these items, reported net earnings for the second quarter of 2016 were $238 million or $0.83 per share, compared with reported net earnings for the second quarter of 2015 of $290 million or $1.02 per share. Excluding these items, adjusted net earnings for the second quarter of 2016 were $305 million or $1.06 per share, compared with adjusted net earnings for the second quarter of 2015 of $293 million or $1.03

per share. A reconciliation of the company’s non-GAAP adjusted results to the company’s GAAP reported results is provided in the schedules at the end of the press release.

The sum of the components may not equal the total due to rounding and quantities of shares outstanding in different periods.

Tax rates vary and are applied based on the item’s nature and tax jurisdiction where it is incurred.

Non-GAAP Financial Measures

The company provides the following non-GAAP financial measures that St. Jude Medical management believes are pertinent to ongoing business performance. St. Jude Medical management uses these non-GAAP financial measures to forecast and evaluate the operational performance of the company as well as to compare results of current periods to prior periods on a consolidated basis.

·                  Adjusted earnings before noncontrolling interest and income taxes

·                  Adjusted income taxes and adjusted effective tax rate

·                  Adjusted net earnings before noncontrolling interest

·                  Adjusted net loss attributable to noncontrolling interest

·                  Adjusted net earnings attributable to St. Jude Medical, Inc.

·                  Adjusted diluted net earnings per share attributable to St. Jude Medical, Inc. and adjusted diluted EPS growth rate

·                  Adjusted constant currency diluted net earnings per share attributable to St. Jude Medical, Inc. and adjusted constant currency diluted EPS growth rate

The adjustments made to GAAP financial measures result from facts and circumstances that vary in frequency and impact on the company’s results of operations. The following is an explanation of each of the adjustments that management excludes in calculating its non-GAAP measures.

Restructuring activities — These amounts represent severance costs and other termination benefits, inventory write-offs primarily associated with discontinued product lines, fixed asset write-offs related to assets no longer expected to be utilized, other restructuring costs and restructuring-related costs.

Acquisition-related costs — These amounts consist of contingent consideration fair value adjustments, acquired inventory step-up amortization, other transaction costs, integration costs, financing commitment fees and stock-based compensation expense for accelerated and replacement equity awards.

Product field action costs and litigation costs — These amounts primarily relate to inventory write-off and disposal costs, additional warranty and patient monitoring costs, and estimated legal costs for outstanding legal matters associated with product field actions.

Legal settlements — These amounts consist of losses that are probable and reasonably estimable, gains related to favorable resolutions of litigation matters and probable insurance recoveries.

Strategic investment impairments — These amounts consist of other-than-temporary impairments of certain strategic investments in debt and equity securities.

Amortization of intangible assets — These amounts represent the non-cash amortization expenses St. Jude Medical recognized for definite-lived intangible assets.

Income tax adjustments — These amounts represent tax effects related to significant unusual or infrequent items not attributable to current-year ordinary income, such as settlement of tax positions and discrete tax adjustments to uncertain tax positions, and certain other tax adjustments.

R&D credit — These amounts represent the impact of the federal research and development tax credit to present comparative periods assuming that the tax credit had been applicable in all periods presented.

Foreign currency impact — These amounts represent the impact to net sales and adjusted diluted net earnings per share attributable to St. Jude Medical, Inc. after translating net sales and the consolidated statement of earnings at comparable prior period foreign currency exchange rates.

The company provides comparable constant currency sales growth because St. Jude Medical management believes that in order to understand the company’s short-term and long-term financial trends, investors may wish to consider the impact of the Thoratec acquisition and foreign currency translation on net sales. St. Jude Medical management uses comparable constant currency sales growth to forecast and evaluate the operational performance of the company as well as to compare sales of current periods to prior periods.

In calculating comparable constant currency sales growth in its non-GAAP measures, the company a) excludes the impact to net sales after translating net sales at prior period foreign currency exchange rates and b) includes Thoratec sales amounts for periods prior to St. Jude Medical’s acquisition of Thoratec. Comparable constant currency sales amounts have not been adjusted to eliminate historical product sales between St. Jude Medical and Thoratec because management believes that such adjustments are not material.

The company also provides constant currency sales growth and constant currency adjusted EPS growth because St. Jude Medical management believes that in order to understand the company’s short-term and long-term financial trends, investors may wish to consider the impact of foreign currency translation on net sales and adjusted EPS. St. Jude Medical management uses constant currency sales growth and constant currency adjusted EPS growth to forecast and evaluate the operational performance of the company as well as to compare sales and adjusted EPS of current periods to prior periods.

Non-GAAP financial measures used by the company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. Investors should consider non-GAAP measures in addition to, and not as a substitute for, or superior to, financial performance measures prepared in accordance with GAAP.
