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.

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.

Pipeline and Portfolio Highlights

Merck continued to achieve regulatory and clinical milestones across its expansive pipeline and portfolio. 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 margin^2	Approximately 77%	Approximately 77%
Non-GAAPOperating expenses^2**	$39.8 to $40.4 billion	$34.0 to $34.6 billion
Non-GAAPOther (income) expense, net^2	Approximately $200 million	Approximately $100 million
Non-GAAPEffective tax rate^2***	39.0% to 40.0%	30.5% to 31.5%
Non-GAAPEPS^2****	$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.

^1 Net income attributable to Merck & Co., Inc.

^2 Merck is providing certain 2023 and 2022 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 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.

Only the line items that are affected by non-GAAP adjustments are shown.
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.
