Generally Accepted Accounting Principles (GAAP) earnings per share (EPS) assuming dilution was $1.86 for the third quarter of 2023. Non-GAAP EPS was $2.13 for the third quarter of 2023. The increases in GAAP and non-GAAP EPS in the third quarter versus the prior year were primarily due to operational strength in the business, as well as $0.22 of charges recorded in 2022 related to collaboration and licensing agreements with Moderna, Inc. (Moderna), Orna Therapeutics (Orna) and Orion Corporation (Orion). The increase in GAAP EPS in the third quarter of 2023 was also driven by the impacts of intangible asset impairment charges recorded in 2022, compared with no such charges recorded in 2023, and lower losses from investments in equity securities in 2023. The increases in both GAAP and non-GAAP EPS in the third quarter were partially offset by the unfavorable impact of foreign exchange. Non-GAAP EPS excludes acquisition- and divestiture-related costs, costs related to restructuring programs, as well as income and losses from investments in equity securities. Year-to-date results can be found in the attached tables. Third-Quarter Sales Performance The following table reflects sales of the company’s top products and significant performance drivers.

Excluding LAGEVRIO, growth of 9%. Excluding LAGEVRIO and unfavorable impact of foreign exchange, growth of 10%. KEYTRUDA 6,338 5,426 17% 17% Growth driven by increased global uptake in earlier-stage indications, including triple-negative breast cancer (TNBC) and renal cell carcinoma (RCC), and continued strong global demand from metastatic indications. GARDASIL / GARDASIL 9 2,585 2,294 13% 16% Growth due to strong demand, particularly in China, and higher pricing in the U.S., partially offset by public-sector buying patterns in the U.S. JANUVIA / JANUMET 835 1,133 -26% -25% Decline primarily due to generic competition in several international markets, particularly in Europe, and lower demand in the U.S. PROQUAD, M-M-R II and VARIVAX 713 668 7% 6% Growth largely due to higher pricing in the U.S. LAGEVRIO 640 436 47% 51% Growth largely attributable to higher demand in Japan, partially offset by lower demand in Australia and nonrecurrence of sales in the U.K. BRIDION 424 423 0% 0% Relatively flat compared with prior year due to higher demand in the U.S., offset by generic competition primarily in Europe. Lynparza* 299 284 5% 6% Growth driven primarily by higher pricing in the U.S. and increased demand in Latin America. Lenvima* 260 202 29% 30% Growth primarily due to higher demand in the U.S. and certain international markets, and timing of shipments in China. VAXNEUVANCE 214 16 ***N/M N/M Growth driven largely by continued uptake in pediatric indication in the U.S. and launches in Europe. Animal Health 1,400 1,371 2% 2% Growth primarily driven by higher pricing in both Livestock and Companion Animal product portfolios. Livestock 874 829 5% 7% Growth primarily due to higher pricing across product portfolio, as well as higher demand for ruminant, poultry and swine products. Companion Animal 526 542 -3% -4% Decline primarily due to lower vet visits in the U.S., partially offset by higher pricing. Sales of BRAVECTO were $235 million and $241 million in the current and prior-year quarters, respectively, which represented a decline of 3%. Other Revenues** 299 625 -52% -18% Decline primarily due to impact of revenue hedging. Excluding unfavorable impact of foreign exchange, decline due to lower revenue from third-party manufacturing arrangements. *Alliance revenue for this product represents Merck’s share of profits, which are product sales net of cost of sales and commercialization costs. **Other revenues are comprised primarily of revenues from third-party manufacturing arrangements and miscellaneous corporate revenues, including revenue-hedging activities. ***Not meaningful Third-Quarter Expense, EPS and Related Information The table below presents selected expense information. $ in millions GAAP Acquisition- and Divestiture- Related Costs3 Restructuring Costs (Income) Loss From Investments in Equity Securities Non- GAAP2 Third Quarter 2023 Cost of sales $4,264 $552 $33 $- $3,679 Selling, general and administrative 2,519 17 40 - 2,462 Research and development 3,307 10 - - 3,297 Restructuring costs 126 - 126 - - Other (income) expense, net 126 (24) - 17 133 Third Quarter 2022 Cost of sales $3,934 $446 $54 $- $3,434 Selling, general and administrative 2,520 22 26 - 2,472 Research and development 4,399 902 1 - 3,496 Restructuring costs 94 - 94 - - Other (income) expense, net 429 (26) - 350 105 GAAP Expense, EPS and Related Information Gross margin was 73.3% for the third quarter of 2023 compared with 73.7% for the third quarter of 2022. The decrease was primarily due to the unfavorable impact of foreign exchange, higher LAGEVRIO sales, which have a low gross margin, and higher acquisition- and divestiture-related costs. The gross margin decline was partially offset by lower revenue from third-party manufacturing arrangements, lower manufacturing-related costs and the favorable impact of product mix. Selling, general and administrative (SG&A) expenses were $2.5 billion in both the third quarters of 2023 and 2022, primarily reflecting increased promotional spending, offset by lower administrative costs. Research and development (R&D) expenses were $3.3 billion in the third quarter of 2023 compared with $4.4 billion in the third quarter of 2022. The decrease was primarily due to charges recorded in 2022 of $887 million for intangible asset impairments, largely related to nemtabrutinib, and $690 million for collaboration and licensing agreements with Moderna, Orna and Orion. The decrease in R&D expenses was partially offset by higher compensation and benefit costs in 2023, reflecting in part increased headcount, higher investments in discovery research and early drug development and higher clinical development spending. Other (income) expense, net, was $126 million of expense in the third quarter of 2023 compared with $429 million of expense in the third quarter of 2022, primarily due to lower net losses from investments in equity securities. The effective tax rate was 15.5% for the third quarter of 2023 compared with 9.2% in the third quarter of 2022. GAAP EPS was $1.86 for the third quarter of 2023 compared with $1.28 for the third quarter of 2022. Non-GAAP Expense, EPS and Related Information Non-GAAP gross margin was 77.0% for both the third quarters of 2023 and 2022, due to the unfavorable impact of foreign exchange, and higher LAGEVRIO sales, which have a low gross margin, offset by lower revenue from third-party manufacturing arrangements, lower manufacturing-related costs and the favorable impact of product mix. Non-GAAP SG&A expenses were $2.5 billion in both the third quarters of 2023 and 2022, primarily reflecting increased promotional spending, offset by lower administrative costs. Non-GAAP R&D expenses were $3.3 billion in the third quarter of 2023 compared with $3.5 billion in the third quarter of 2022. The decrease was primarily due to charges of $690 million in 2022 related to collaboration and licensing agreements with Moderna, Orna and Orion. The decrease in R&D expenses was partially offset by higher compensation and benefit costs in 2023, reflecting in part increased headcount, higher investments in discovery research and early drug development and higher clinical development spending. Non-GAAP other (income) expense, net, was $133 million of expense in the third quarter of 2023 compared with $105 million of expense in the third quarter of 2022. The non-GAAP effective tax rate was 15.0% for the third quarter of 2023 compared with 13.6% in the third quarter of 2022. Non-GAAP EPS was $2.13 for the third quarter of 2023 compared with $1.85 for the third quarter of 2022. A reconciliation of GAAP to non-GAAP net income and EPS is provided in the table that follows.

The company is initiating Phase 3 trials in 2023 in multiple therapeutic areas, including oncology, cardiometabolic and immunology, and in new modalities. These include investigational individualized neoantigen therapy V940 in combination with KEYTRUDA, antibody-drug conjugate (ADC) MK-2870 and lysine-specific demethylase-1 inhibitor MK-3543 in oncology, oral PCSK9 inhibitor candidate MK-0616 in cardiovascular, and humanized monoclonal antibody MK-7240 in immunology. In oncology, the company received U.S. Food and Drug Administration (FDA) approval of KEYTRUDA for the treatment of certain patients with resectable non-small cell lung cancer (NSCLC) as a neoadjuvant/adjuvant treatment, the company’s eighth approval of KEYTRUDA in earlier-stage cancer. The FDA also granted priority review to two supplemental New Drug Applications (sNDAs): for WELIREG in certain previously treated patients with advanced RCC, and for KEYTRUDA in cervical cancer. Notably, Merck presented compelling new data at the European Society for Medical Oncology (ESMO) Congress 2023 that showcased the company’s progress in earlier stages of cancers, its foundational position in metastatic disease and continued momentum in its diverse oncology pipeline. In cardiovascular disease, Merck received priority review from the FDA for a new Biologics License Application (BLA) for sotatercept, the company’s novel investigational activin signaling inhibitor for the treatment of adults with pulmonary arterial hypertension (PAH) (World Health Organization Group 1), based on clinically meaningful results from the Phase 3 STELLAR trial. The FDA set a Prescription Drug User Fee Act (PDUFA), or target action, date of March 26, 2024. If approved, sotatercept would be the first in its class, bringing a novel approach to address a rare and progressive disease of the pulmonary arteries. Merck’s submission for sotatercept to the Committee for Medicinal Products for Human Use (CHMP) in the European Union (EU) has also been completed. Additionally, Merck entered into a collaboration agreement with Daiichi Sankyo for three potentially first-in-class clinical-stage DXd ADCs for the treatment of multiple solid tumors, both as monotherapy and/or in combination with other treatments. This collaboration with Daiichi Sankyo will further augment and diversify Merck’s oncology pipeline.

Full-Year 2023 Financial Outlook The following table summarizes the company’s full-year financial outlook. Full Year 2023 Updated Prior Sales* $59.7 to $60.2 billion $58.6 to $59.6 billion Non-GAAP Gross margin2 Approximately 77% Approximately 77% Non-GAAP Operating expenses2** $39.8 to $40.4 billion $34.0 to $34.6 billion Non-GAAP Other (income) expense, net2 Approximately $200 million Approximately $100 million Non-GAAP Effective tax rate2*** 39.0% to 40.0% 30.5% to 31.5% Non-GAAP EPS2**** $1.33 to $1.38 $2.95 to $3.05 Share count (assuming dilution) 2.55 billion 2.55 billion *Includes approximately $1.3 billion of LAGEVRIO sales. The company does not have any non-GAAP adjustments to sales. **Includes an aggregate $17.1 billion of R&D expenses related to the Prometheus Biosciences, Inc. (Prometheus) and Imago BioSciences, Inc. (Imago) acquisitions, and upfront payments for the license and collaboration agreement with Kelun-Biotech (a holding subsidiary of Sichuan Kelun Pharmaceutical Co., Ltd) and collaboration agreement with Daiichi Sankyo. Outlook does not assume any additional significant potential business development transactions. ***Includes an approximate 24.5 percentage point negative impact related to business development (Imago, Prometheus and Daiichi Sankyo). ****Includes $6.22 of one-time charges related to the Prometheus and Imago acquisitions and upfront payments to Kelun-Biotech and Daiichi Sankyo. Merck has not provided a reconciliation of forward-looking non-GAAP gross margin, non-GAAP operating expenses, non-GAAP other (income) expense, net, non-GAAP effective tax rate and non-GAAP EPS to the most directly comparable GAAP measures, given it cannot predict with reasonable certainty the amounts necessary for such a reconciliation, including intangible asset impairment charges, legal settlements, and income and losses from investments in equity securities either owned directly or through ownership interests in investment funds, without unreasonable effort. These items are inherently difficult to forecast and could have a significant impact on the company’s future GAAP results. Merck continues to experience strong sustained demand for key growth products, particularly in oncology and vaccines. As a result, Merck is raising and narrowing its full-year sales outlook. Merck now expects full-year sales to be between $59.7 billion and $60.2 billion, including a negative impact of foreign exchange of approximately 2 percentage points, at mid-October 2023 exchange rates. This full-year outlook includes approximately $1.3 billion of LAGEVRIO sales. Merck’s full-year non-GAAP effective income tax rate is expected to be between 39.0% and 40.0%, which includes an approximate 24.5 percentage point negative impact related to business development activity. Merck now expects its full-year non-GAAP EPS to be between $1.33 and $1.38, including a negative impact of foreign exchange of approximately 6 percentage points, at mid-October 2023 exchange rates. This revised non-GAAP EPS range reflects the following, which were not previously included in the outlook: Additional strength in the business of approximately $0.15 per share. A pretax charge of $5.5 billion, or $1.70 per share, for the collaboration agreement with Daiichi Sankyo. Estimated expense in the fourth quarter of 2023 of approximately $0.04 per share to advance the ADC assets and finance the transaction with Daiichi Sankyo. A 1%, or approximately $0.05 per share, incremental negative impact of foreign exchange. The non-GAAP EPS range excludes acquisition- and divestiture-related costs, costs related to restructuring programs, income and losses from investments in equity securities, and a previously disclosed charge related to settlements with certain plaintiffs in the Zetia antitrust litigation.

Management believes that providing this information enhances investors’ understanding of the company’s results because management uses non-GAAP results to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the company along with other metrics. In addition, senior management’s annual compensation is derived in part using a non-GAAP pretax income metric. This information should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. For a description of the non-GAAP adjustments, see Table 2a attached to this release. 3 Includes expenses for the amortization of intangible assets and purchase accounting adjustments to inventories recognized as a result of acquisitions of businesses, intangible asset impairment charges and expense or income related to changes in the estimated fair value measurement of liabilities for contingent consideration. R&D expenses in the third quarter of 2022 include intangible asset impairment charges of $887 million largely related to nemtabrutinib. Also includes integration, transaction and certain other costs associated with acquisitions and divestitures, as well as amortization of intangible assets related to collaborations and licensing arrangements.

Merck is providing certain non-GAAP information that excludes certain items because of the nature of these items and the impact they have on the analysis of underlying business performance and trends. Management believes that providing non-GAAP information enhances investors’ understanding of the company’s results because management uses non-GAAP measures to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the company along with other metrics. In addition, senior management’s annual compensation is derived in part using a non-GAAP pretax income metric. The non-GAAP information presented should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. (1) Amounts included in cost of sales primarily reflect expenses for the amortization of intangible assets. Amounts included in selling, general and administrative expenses reflect integration, transaction and certain other costs related to acquisitions and divestitures. Amounts included in research and development expenses primarily reflect expenses for the amortization of intangible assets. Amounts included in other (income) expense, net, primarily reflect royalty income, partially offset by an increase in the estimated fair value measurement of liabilities for contingent consideration related to the prior termination of the Sanofi-Pasteur MSD joint venture. Additionally, the nine-month period includes a $37 million loss on the sale of a business. (2) Amounts primarily include employee separation costs and accelerated depreciation associated with facilities to be closed or divested related to activities under the company's formal restructuring programs. (3) Reflects a charge related to settlements with certain plaintiffs in the Zetia antitrust litigation. (4) Represents the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments. MERCK & CO., INC.

Non-GAAP loss per share was $2.06 for the second quarter of 2023. Both GAAP and non-GAAP loss per share were due to a charge for the acquisition of Prometheus Biosciences, Inc. (Prometheus) of $4.02 per share. Additionally, both GAAP and non-GAAP loss per share in the second quarter of 2023 were unfavorably affected by lower sales of LAGEVRIO and the impact of foreign exchange compared with the second quarter of 2022. Non-GAAP EPS excludes acquisition- and divestiture-related costs and costs related to restructuring programs, as well as income and losses from investments in equity securities.

Excluding LAGEVRIO, growth of 14%. Excluding LAGEVRIO and unfavorable impact of foreign exchange, growth of 17%. KEYTRUDA 6,271 5,252 19% 21% Growth from continued strong global momentum in metastatic indications, including certain types of non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), head and neck squamous cell carcinoma and triple-negative breast cancer (TNBC), and increased uptake across earlier-stage indications, including certain types of neoadjuvant/adjuvant TNBC in the U.S. GARDASIL / GARDASIL 9 2,458 1,674 47% 53% Growth largely due to strong global demand, particularly in China. JANUVIA / JANUMET 864 1,233 -30% -28% Decline primarily due to generic competition in several international markets, particularly in Europe, and lower demand and pricing in the U.S. PROQUAD, M-M-R II and VARIVAX 582 578 1% 1% Relatively flat compared with prior year. BRIDION 502 426 18% 19% Growth primarily due to increased demand, particularly in the U.S., reflecting an increase in market share among neuromuscular blockade reversal agents.

Livestock 807 826 -2% 2% Excluding unfavorable impact of foreign exchange, growth due to higher pricing, as well as higher demand for swine and poultry products, partially offset by lower demand for ruminant products, due in part to reduced herd sizes. Companion Animal 649 641 1% 2% Growth driven by higher pricing, including for the BRAVECTO line of products, partially offset by supply challenges for certain companion animal vaccines. Sales of BRAVECTO were $326 million and $309 million in the current and prior quarters, respectively, which represented growth of 5% or 7% excluding unfavorable impact of foreign exchange. Other Revenues** 122 370 -67% -19% Decline primarily due to impact of revenue hedging. Excluding unfavorable impact of foreign exchange, decline due to lower royalties and milestone payments received for out-licensing arrangements. *Alliance revenue for this product represents Merck’s share of profits, which are product sales net of cost of sales and commercialization costs. **Other revenues are comprised primarily of revenues from third-party manufacturing arrangements and miscellaneous corporate revenues, including revenue-hedging activities. ***Not meaningful Second-Quarter Expense, EPS and Related Information The table below presents selected expense information. $ in millions GAAP Acquisition- and Divestiture- Related Costs3 Restructuring Costs (Income) Loss From Investments in Equity Securities Non- GAAP2 Second Quarter 2023 Cost of sales $4,024 $467 $32 $- $3,525 Selling, general and administrative 2,702 25 52 - 2,625 Research and development 13,321 9 1 - 13,311 Restructuring costs 151 - 151 - - Other (income) expense, net 172 (3) - 194 (19) Second Quarter 2022 Cost of sales $4,216 $451 $67 $- $3,698 Selling, general and administrative 2,512 65 27 - 2,420 Research and development 2,798 12 22 - 2,764 Restructuring costs 142 - 142 - - Other (income) expense, net 438 2 - 234 202 GAAP Expense, EPS and Related Information Gross margin was 73.2% for the second quarter of 2023 compared with 71.1% for the second quarter of 2022. The increase was primarily due to lower LAGEVRIO sales, which have a low gross margin, as well as the favorable impact of product mix. The gross margin increase was partially offset by the unfavorable impact of foreign exchange. Selling, general and administrative (SG&A) expenses were $2.7 billion in the second quarter of 2023, an increase of 8% compared with the second quarter of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, and higher promotional spending, partially offset by lower acquisition- and divestiture- related costs and the favorable impact of foreign exchange. Research and development (R&D) expenses were $13.3 billion in the second quarter of 2023 compared with $2.8 billion in the second quarter of 2022. The increase was primarily due to a $10.2 billion charge for the acquisition of Prometheus. The remaining increase was driven by higher compensation and benefit costs, reflecting in part increased headcount, higher investments in discovery research and early drug development, and higher clinical development spending. Other (income) expense, net, was $172 million of expense in the second quarter of 2023 compared with $438 million of expense in the second quarter of 2022, primarily due to lower net losses from investments in equity securities and lower pension settlement costs. The income tax provision for the second quarter of 2023 was $637 million on a pretax loss of $5.3 billion, resulting in an effective tax rate of (11.9)%. This effective tax rate includes a 25.1 percentage point unfavorable impact of the charge for the acquisition of Prometheus, for which no tax benefit was recorded. GAAP loss per share was $2.35 for the second quarter of 2023 compared with earnings per share of $1.55 for the second quarter of 2022. Non-GAAP Expense, EPS and Related Information Non-GAAP gross margin was 76.6% for the second quarter of 2023 compared with 74.7% for the second quarter of 2022. The increase was primarily due to lower LAGEVRIO sales, which have a low gross margin, as well as the favorable impact of product mix. The gross margin increase was partially offset by the unfavorable impact of foreign exchange. Non-GAAP SG&A expenses were $2.6 billion in the second quarter of 2023, an increase of 8% compared with the second quarter of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, and higher promotional spending, partially offset by the favorable impact of foreign exchange. Non-GAAP R&D expenses were $13.3 billion in the second quarter of 2023 compared with $2.8 billion in the second quarter of 2022. The increase was primarily due to a $10.2 billion charge for the acquisition of Prometheus. The remaining increase was driven by higher compensation and benefit costs, reflecting in part increased headcount, higher investments in discovery research and early drug development, and higher clinical development spending. Non-GAAP other (income) expense, net, was $19 million of income in the second quarter of 2023 compared with $202 million of expense in the second quarter of 2022, primarily due to lower pension settlement costs. The non-GAAP income tax provision for the second quarter of 2023 was $810 million on a pretax loss of $4.4 billion, resulting in a non-GAAP effective tax rate of (18.4)%. This effective tax rate includes a 32.5 percentage point unfavorable impact of the charge for the acquisition of Prometheus, for which no tax benefit was recorded. Non-GAAP loss per share was $2.06 for the second quarter of 2023 compared with earnings per share of $1.87 for the second quarter of 2022. A reconciliation of GAAP to non-GAAP net (loss) income and EPS is provided in the table that follows.

In oncology, the company reached regulatory milestones across different stages of cancer and shared positive results from a range of clinical trials. Notably, Merck presented data on four approved medicines and two pipeline candidates in more than 25 types of cancer at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting, including investigational data for KEYTRUDA that demonstrates its progress in earlier stages of disease. Further, in vaccines, Merck announced positive topline results demonstrating that V116, an investigational 21-valent pneumococcal conjugate vaccine specifically designed for adults, met key immunogenicity and safety endpoints in two Phase 3 trials. In cardiovascular, Merck submitted a Biologics License Application to the U.S. Food and Drug Administration (FDA) for sotatercept, Merck’s novel investigational activin signaling inhibitor for the treatment of adults with pulmonary arterial hypertension (World Health Organization Group 1). In chronic cough, Merck received an acceptance from the FDA for the resubmission of the New Drug Application for gefapixant and assigned a target action date of Dec. 27, 2023. Merck also completed the acquisition of Prometheus, which will accelerate the company’s growing presence in immunology and add diversity to its pipeline.

Sales* $58.6 to $59.6 billion Non-GAAP Gross margin2 Approximately 77% Non-GAAP Operating expenses2** $34.0 to $34.6 billion Non-GAAP Other (income) expense, net2 Approximately $100 million Non-GAAP Effective tax rate2*** 30.5% to 31.5% Non-GAAP EPS2**** $2.95 to $3.05 Share count (assuming dilution) 2.55 billion *Includes approximately $1.0 billion of LAGEVRIO sales. The company does not have any non-GAAP adjustments to sales. **Includes an aggregate $11.6 billion of R&D expenses related to the Prometheus and Imago BioSciences, Inc. (Imago) acquisitions and upfront payment for the license and collaboration agreement with Kelun-Biotech (a holding subsidiary of Sichuan Kelun Pharmaceutical Co., Ltd). Outlook does not assume any additional significant potential business development transactions. ***Includes a negative impact of 15 percentage points from the one-time charge for the acquisition of Prometheus. ****Includes $4.53 of one-time charges related to the Prometheus and Imago acquisitions and upfront payment to Kelun-Biotech. Merck has not provided a reconciliation of forward-looking non-GAAP gross margin, non-GAAP operating expenses, non-GAAP other (income) expense, net, non-GAAP effective tax rate and non-GAAP EPS to the most directly comparable GAAP measures, given it cannot predict with reasonable certainty the amounts necessary for such a reconciliation, including intangible asset impairment charges, legal settlements, and gains and losses from investments in equity securities either owned directly or through ownership interests in investment funds, without unreasonable effort. These items are inherently difficult to forecast and could have a significant impact on the company’s future GAAP results. Merck continues to experience strong global demand for key growth products, particularly in oncology and vaccines. As a result, Merck is raising and narrowing its full-year sales outlook. Merck now expects full-year sales to be between $58.6 billion and $59.6 billion, including a negative impact of foreign exchange of approximately 2 percentage points, at mid-July 2023 exchange rates. This full-year outlook continues to include approximately $1.0 billion of LAGEVRIO sales. Merck’s full-year non-GAAP effective income tax rate is expected to be between 30.5% and 31.5%, including an unfavorable impact of approximately 15 percentage points from the non-tax deductible one-time charge for the acquisition of Prometheus. Merck now expects its full-year non-GAAP EPS to be between $2.95 and $3.05, including a negative impact of foreign exchange of approximately 5 percentage points, at mid-July 2023 exchange rates. This revised non-GAAP EPS range reflects the following, which were not previously included in the outlook: Additional strength in the business of approximately $0.24 per share. A charge of $10.2 billion, or $4.02 per share, for the acquisition of Prometheus. Estimated 2023 expense of approximately $0.14 per share to be incurred to finance the Prometheus acquisition and to advance the acquired assets. A less than 1%, or approximately $0.02 per share, incremental negative impact of foreign exchange. The non-GAAP EPS range excludes acquisition- and divestiture-related costs and costs related to restructuring programs, as well as income and losses from investments in equity securities, and a previously disclosed charge related to settlements with certain plaintiffs in the Zetia antitrust litigation.

Management believes that providing this information enhances investors’ understanding of the company’s results because management uses non-GAAP results to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the company along with other metrics. In addition, senior management’s annual compensation is derived in part using a non-GAAP pre-tax income metric. This information should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. For a description of the non-GAAP adjustments, see Table 2a attached to this release. 3 Includes expenses for the amortization of intangible assets and purchase accounting adjustments to inventories recognized as a result of acquisitions of businesses, intangible asset impairment charges and expense or income related to changes in the estimated fair value measurement of liabilities for contingent consideration. Also includes integration, transaction and certain other costs associated with acquisitions and divestitures, as well as amortization of intangible assets related to collaborations and licensing arrangements.

Management believes that providing non-GAAP information enhances investors’ understanding of the company’s results because management uses non-GAAP measures to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the company along with other metrics. In addition, senior management’s annual compensation is derived in part using a non-GAAP pretax income metric. The non-GAAP information presented should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. (1) Amounts included in cost of sales primarily reflect expenses for the amortization of intangible assets. Amounts included in selling, general and administrative expenses reflect integration, transaction and certain other costs related to acquisitions and divestitures. Amounts included in research and development expenses primarily reflect expenses for the amortization of intangible assets. Amounts included in other (income) expense, net, for the six-month period primarily reflect a $37 million loss on the sale of a business and an increase in the estimated fair value measurement of liabilities for contingent consideration related to the prior termination of the Sanofi-Pasteur MSD joint venture, partially offset by royalty income. (2) Amounts primarily include employee separation costs and accelerated depreciation associated with facilities to be closed or divested related to activities under the company's formal restructuring programs. (3) Reflects a charge related to settlements with certain plaintiffs in the Zetia antitrust litigation. (4) Represents the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments. (5) Because the company recorded a net loss in the second quarter and first six months of 2023, no potential dilutive common shares were used in the computation of loss per common share assuming dilution as the effect would have been anti-dilutive.
