Unless otherwise stated, all comparisons are for the second quarter of 2019 compared to the second quarter of 2018. The adjusted operating expense categories presented below exclude share-based employee compensation expense and collaboration-related upfront expense. Please see the attached Use of Non-GAAP Financial Measures and Reconciliation of GAAP to Adjusted Net Income for further information relevant to the interpretation of adjusted financial measures and reconciliations of these adjusted financial measures to the most comparable GAAP measures, respectively.

• REVLIMID^® sales for the second quarter were $2,732 million, an increase of 11 percent year-over-year. U.S. sales were $1,810 million and international sales were $922 million, an increase of 14 percent and 6 percent year-over-year, respectively. REVLIMID^® sales growth was driven primarily by the adoption of triplet therapy for myeloma resulting in increases in treatment duration and market share.
• POMALYST^®/IMNOVID^® sales for the second quarter were $619 million, an increase of 22 percent year-over-year. U.S. sales were $447 million and international sales were $172 million, an increase of 31 percent and 4 percent year-over-year, respectively. POMALYST^®/IMNOVID^® sales growth was driven primarily by the adoption of triplet therapy for myeloma resulting in increases in treatment duration and market share.
• OTEZLA^® sales for the second quarter were $493 million, an increase of 31 percent year-over-year. U.S. sales were $399 million and international sales were $94 million, an increase of 37 percent and 12 percent year-over-year, respectively. OTEZLA^® sales growth in the U.S. was driven by increase in demand and customer buying patterns, while international sales were driven by continued expansion in key markets.

• ABRAXANE^® sales for the second quarter were $316 million, an increase of 30 percent year-over-year. U.S. sales were $207 million and international sales were $109 million, an increase of 36 percent and 20 percent year-over-year, respectively. ABRAXANE^® sales growth was driven primarily by increased demand due to immuno-oncology (IO) combinations in non-small cell lung cancer (NSCLC) and triple-negative breast cancer (TNBC).

• In the secondquarter, all other product sales, which include IDHIFA^®, THALOMID^®, ISTODAX^®, VIDAZA^® and an authorized generic version of VIDAZA^® drug product primarily sold in the U.S., were $239 million compared to $230 million in the second quarter of 2018.

On a GAAP basis, R&D expenses were $1,100 million for the second quarter of 2019 compared to $1,251 million for the same period in 2018. Adjusted R&D expenses were $935 million for the second quarter of 2019 compared to $948 million for the second quarter of 2018. The decrease was driven by a reduction in expenses related to certain collaboration arrangements and regulatory submission-related work on multiple programs almost fully offset by increased investments in ongoing late-stage pipeline programs. Additional R&D expenses (only included on a GAAP basis) decreased in 2019, as outlined in the attached Reconciliation of GAAP to Adjusted Net Income.

On a GAAP basis, SG&A expenses were $793 million for the second quarter of 2019 compared to $790 million for the same period in 2018. Adjusted SG&A expenses were $693 million for the second quarter of 2019 compared to $672 million for the second quarter of 2018. The increase was driven primarily by increased pre-launch marketing related expenses partially offset by a decrease in expense related to technology investments completed in 2018. Additional SG&A expense (only included on a GAAP basis) decreased in 2019, as outlined in the attached Reconciliation of GAAP to Adjusted Net Income.

This press release contains forward-looking statements, which are generally statements that are not historical facts. Forward-looking statements can be identified by the words "expects," "anticipates," "believes," "intends," "estimates," "plans," "will," "outlook" and similar expressions. Forward-looking statements are based on management's current plans, estimates, assumptions and projections, and speak only as of the date they are made. We undertake no obligation to update any forward-looking statement in light of new information or future events, except as otherwise required by law. Forward-looking statements involve inherent risks and uncertainties, most of which are difficult to predict and are generally beyond our control. Actual results or outcomes may differ materially from those implied by the forward-looking statements as a result of the impact of a number of factors, many of which are discussed in more detail in our Annual Report on Form 10-K and our other reports filed with the Securities and Exchange Commission, including factors related to the proposed transaction between Bristol-Myers Squibb and Celgene, such as, but not limited to, the risks that: management's time and attention is diverted on transaction related issues, including the planned divestiture of OTEZLA^®; disruption from the proposed transaction makes it more difficult to maintain business, contractual and operational relationships; legal proceedings are instituted against Bristol-Myers Squibb, Celgene or the combined company; and Bristol-Myers Squibb, Celgene or the combined company is unable to retain key personnel.

Management uses such measures internally for planning and forecasting purposes and to measure the performance of the Company. We believe these adjusted financial measures provide useful and meaningful information to us and investors because they enhance investors' understanding of the continuing operating performance of our business and facilitate the comparison of performance between past and future periods. These adjusted financial measures are non-GAAP measures and should be considered in addition to, but not as a substitute for, the information prepared in accordance with U.S. GAAP. When preparing these supplemental non-GAAP financial measures we typically exclude certain GAAP items that management does not consider to be normal, recurring cash operating expenses but that may not meet the definition of unusual or non-recurring items. Other companies may define these measures in different ways. The following categories of items are excluded from adjusted financial results:

Acquisition/Integration and Divestiture Related Costs: We exclude the impact of certain amounts recorded in connection with business combinations and divestitures from our adjusted financial results that are either non-cash or not normal, recurring operating expenses due to their nature, variability of amounts, and lack of predictability as to occurrence and/or timing. These amounts may include non-cash items such as the amortization of acquired intangible assets, amortization of purchase accounting adjustments to inventories, intangible asset impairment charges and expense or income related to changes in the estimated fair value measurement of contingent consideration and success payments. We also exclude transaction and certain other cash costs associated with business acquisitions and divestitures that are not normal, recurring operating expenses, including severance costs which are not part of a formal restructuring program as well as integration preparation costs associated with our merger with Bristol-Myers Squibb.

Collaboration-Related Upfront Expenses: We exclude collaboration-related upfront expenses from our adjusted financial results because we do not consider them to be normal, recurring operating expenses due to their nature, variability of amounts, and lack of predictability as to occurrence and/or timing. Upfront payments to collaboration partners are made at the commencement of a relationship anticipated to continue for a multi-year period and provide us with intellectual property rights, option rights and other rights with respect to particular programs. The variability of amounts and lack of predictability of collaboration-related upfront expenses makes the identification of trends in our ongoing research and development activities more difficult. We believe the presentation of adjusted research and development, which does not include collaboration-related upfront expenses, provides useful and meaningful information about our ongoing research and development activities by enhancing investors' understanding of our normal, recurring operating research and development expenses and facilitates comparisons between periods and with respect to projected performance. All expenses incurred subsequent to the initiation of the collaboration arrangement, such as research and development cost-sharing expenses/reimbursements and milestone payments up to the point of regulatory approval are considered to be normal, recurring operating expenses and are included in our adjusted financial results.

Research and Development Asset Acquisition Expense: We exclude costs associated with acquiring rights to pre-commercial compounds because we do not consider such costs to be normal, recurring operating expenses due to their nature, variability of amounts, and lack of predictability as to occurrence and/or timing. Research and development asset acquisition expenses includes expenses to acquire rights to pre-commercial compounds from a collaboration partner when there will be no further participation from the collaboration partner or other parties. The variability of amounts and lack of predictability of research and development asset acquisition expenses makes the identification of trends in our ongoing research and development activities more difficult. We believe the presentation of adjusted research and development, which does not include research and development asset acquisition expenses, provides useful and meaningful information about our ongoing research and development activities by enhancing investors' understanding of our normal, recurring operating research and development expenses and facilitates comparisons between periods and with respect to projected performance.

Restructuring Costs: We exclude costs associated with restructuring initiatives from our adjusted financial results. These costs include amounts associated with facilities to be closed, employee separation costs and costs to move operations from one location to another. We do not frequently undertake restructuring initiatives and therefore do not consider such costs to be normal, recurring operating expenses.

Certain Other Items: We exclude certain other significant items that may occur occasionally and are not normal, recurring cash operating expenses from our adjusted financial results. Such items are evaluated on an individual basis based on both the quantitative and the qualitative aspect of their nature and generally represent items that, either as a result of their nature or magnitude, we would not anticipate occurring as part of our normal business on a regular basis. While not all-inclusive, examples of certain other significant items excluded from adjusted financial results would be: significant litigation-related loss contingency accruals and expenses to settle other disputed matters and, effective for fiscal year 2018, changes in the fair value of our equity securities upon the adoption of ASU 2016-01 (Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities).

Estimated Tax Impact From Above Adjustments: We exclude the net income tax impact of the non-tax adjustments described above from our adjusted financial results. The net income tax impact of the non-tax adjustments includes the impact on both current and deferred income taxes and is based on the taxability of the adjustment under local tax law and the statutory tax rate in the tax jurisdiction where the adjustment was incurred.

Non-Operating Tax Adjustments: We exclude the net income tax impact of certain other significant income tax items, which are not associated with our normal, recurring operations ("Non-Operating Tax Items"), from our adjusted financial results. Non-Operating Tax Items include items which may occur occasionally and are not normal, recurring operating expenses (or benefits), including adjustments related to acquisitions, divestitures, collaborations, certain adjustments to the amount of unrecognized tax benefits related to prior year tax positions, the impact of tax reform legislation commonly referred to as the Tax Cuts and Jobs Act (2017 Tax Act), and other similar items. We also exclude excess tax benefits and tax deficiencies that arise upon vesting or exercise of share-based payments recognized as income tax benefits or expenses due to their nature, variability of amounts, and lack of predictability as to occurrence and/or timing.

A reconciliation of long-term adjusted financial targets to the most comparable GAAP measures cannot be provided because we are unable to forecast with reasonable certainty many of the items necessary to calculate such comparable GAAP measures, including share-based compensation expense, collaboration-related upfront expense, research and development asset acquisition expense, acquisition-related expenses, fair value adjustments to contingent consideration, the ultimate outcome of legal proceedings and unusual gains and losses, as well as unforeseen events, risks and developments. These items are uncertain, depend on various factors, and could be material to our results computed in accordance with GAAP. We believe the inherent uncertainties in reconciling our long-term non-GAAP measures to the most comparable GAAP measures would make the forecasted comparable GAAP measures nearly impossible to predict with reasonable certainty and therefore inherently unreliable.
