NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1:  Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation: The condensed consolidated financial statements included in this report are unaudited and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and U.S. Securities and Exchange Commission (“SEC”) regulations. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. The condensed consolidated financial statements for the three months ended March 31, 2023, should be read in conjunction with the consolidated financial statements and notes thereto of West Pharmaceutical Services, Inc. and its majority-owned subsidiaries (which may be referred to as “West,” the “Company,” “we,” “us” or “our”) appearing in our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). The results of operations for any interim period are not necessarily indicative of results for the full year.

Note 2:  New Accounting Standards

Recently Adopted Standards

In September 2022, the Financial Accounting Standards Board ("FASB") issued guidance that seeks to enhance transparency around entities' use of supplier finance programs. The amendment requires the buyer in a supplier finance program to disclose information about the key terms of the program, outstanding confirmed amounts as of the end of the period, a rollforward of such amounts during each annual period, and a description of where in the financial statements outstanding amounts are presented. This guidance is effective for fiscal years beginning after December 15, 2022. We adopted this guidance as of January 1, 2023, on a prospective basis. The adoption did not have a material impact on our financial statements, as supplier finance programs are not material to the Company as of March 31, 2023.

Note 3:  Revenue

Our revenue results from the sale of goods or services and reflects the consideration to which we expect to be entitled in exchange for those goods or services. We record revenue based on a five-step model, in accordance with Accounting Standards Codification (“ASC”) 606. Following the identification of a contract with a customer, we identify the performance obligations (goods or services) in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize the revenue when (or as) we satisfy the performance obligations by transferring the promised goods or services to our customers. A good or service is transferred when (or as) the customer obtains control of that good or service.

The following table presents the approximate percentage of our net sales by market group:

	Three Months Ended March 31,
	2023	2022
Biologics	34 %	43 %
Generics	20 %	17 %
Pharma	27 %	24 %
Contract-Manufactured Products	19 %	16 %
	100 %	100 %

The following table presents the approximate percentage of our net sales by product category:

	Three Months Ended March 31,
	2023	2022
High-Value Product Components	51 %	56 %
High-Value Product Delivery Devices	7 %	5 %
Standard Packaging	23 %	23 %
Contract-Manufactured Products	19 %	16 %
	100 %	100 %

The following table presents the approximate percentage of our net sales by geographic location:

	Three Months Ended March 31,
	2023	2022
Americas	44 %	45 %
Europe, Middle East, Africa	47 %	45 %
Asia Pacific	9 %	10 %
	100 %	100 %

Contract Assets and Liabilities

The following table summarizes our contract assets and liabilities, excluding amounts included in accounts receivable, net:

	($ in millions)
Contract assets, December 31, 2022	$	16.3
Contract assets, March 31, 2023	19.4
Change in contract assets - increase (decrease)	$	3.1
Deferred income, December 31, 2022	$	(68.2)
Deferred income, March 31, 2023	(57.5)
Change in deferred income - decrease (increase)	$	10.7

Contract assets are included within other current assets and deferred income is included within other current liabilities and other long-term liabilities. During the three months ended March 31, 2023, $21.3 million of revenue was recognized that was included in deferred income at the beginning of the year.

The majority of the performance obligations within our contracts are satisfied within one year or less. Performance obligations satisfied beyond one year include those relating to a nonrefundable customer payment of $20.0 million received in June 2013 in return for the exclusive use of the SmartDose® technology platform within a specific therapeutic area. As of March 31, 2023, there was $2.8 million of deferred income related to this payment, of which $0.9 million was included in other current liabilities and $1.9 million was included in other long-term liabilities. The deferred income is being recognized as income on a straight-line basis over the remaining term of the agreement. The agreement does not include a future minimum purchase commitment from the customer.

Note 4:  Net Income Per Share

The following table reconciles the shares used in the calculation of basic net income per share to those used for diluted net income per share:

	Three Months Ended March 31,
(in millions)	2023		2022
Net income	$	140.0	$	173.8
Weighted average common shares outstanding	74.5		74.4
Dilutive effect of equity awards, based on the treasury stock method	1.2		1.6
Weighted average shares assuming dilution	75.7		76.0

During the three months ended March 31, 2023 and 2022, there were 0.3 million and 0.0 million shares, respectively, from stock-based compensation plans not included in the computation of diluted net income per share because their impact was antidilutive.

In February 2023, the Board of Directors approved a share repurchase program under which we may repurchase up to $1.0 billion in shares of common stock. The share repurchase program does not have an expiration date under which we may repurchase common stock on the open market or in privately-negotiated transactions. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions.

During the three months ended March 31, 2023, we purchased 183,360 shares of our common stock under the program at a cost of $60.1 million, or an average price of $327.90 per share. During the three months ended March 31, 2022, we purchased 390,000 shares of our common stock under the program at a cost of $147.1 million, or an average price of $377.23 per share.

Note 5:  Inventories

Inventories are valued at the lower of cost (on a first-in, first-out basis) and net realizable value. Inventory balances were as follows:

($ in millions)	March 31, 2023		December 31, 2022
Raw materials	$	181.0	$	170.7
Work in process	95.9		79.0
Finished goods	170.1		165.1
	$	447.0	$	414.8

Note 6:  Leases

A lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: 1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment); and 2) the customer has the right to control the use of the identified asset. Lease payments included in the measurement of the operating lease right-of-use assets and lease liabilities are comprised of fixed payments (including in-substance fixed payments), variable payments that depend on an index or rate, and the exercise price of a lessee option to purchase the underlying asset if the lessee is reasonably certain to exercise.

The components of lease expense were as follows:

	Three Months Ended March 31,
($ in millions)	2023		2022
Operating lease cost	$	5.9	$	3.3
Short-term lease cost	1.3		0.4
Variable lease cost	1.7		1.4
Total lease cost	$	8.9	$	5.1

Cash paid for amounts included in the measurement of lease liabilities:
Operating cash flows from operating leases	$	4.9	$	3.2
Right-of-use assets obtained in exchange for new operating lease liabilities	$	0.6	$	9.7

As of March 31, 2023 and December 31, 2022, the weighted average remaining lease term for operating leases was 9.3 years and 9.3 years, respectively.

As of March 31, 2023 and December 31, 2022, the weighted average discount rate was 3.26% and 3.25%, respectively.

Maturities of operating lease liabilities were as follows:

($ in millions)	March 31,		December 31,
Year	2023		2022
2023 (remaining period as of)	$	14.5	$	19.0
2024	18.3		18.1
2025	16.2		16.0
2026	13.4		13.4
2027	9.3		9.4
Thereafter	51.5		50.8
	123.2		126.7
Less: imputed lease interest	(17.1)		(17.7)
Total lease liabilities	$	106.1	$	109.0

Note 7:  Affiliated Companies

At March 31, 2023 and December 31, 2022, the aggregate carrying amount of our investment in affiliated companies that are accounted for under the equity method was $200.9 million and $197.0 million, respectively, and the aggregate carrying amount of our investment in affiliated companies that are not accounted for under the equity method was $7.9 million and $7.9 million at March 31, 2023 and December 31, 2022, respectively. We have elected to record these investments, for which fair value was not readily determinable, at cost, less impairment, adjusted for subsequent observable price changes. We test these investments for impairment whenever circumstances indicate that the carrying value of the investments may not be recoverable.

10

Our purchases from, and royalty payments made to, affiliates totaled $44.2 million for the three months ended March 31, 2023, as compared to $58.5 million for the same period in 2022. As of March 31, 2023 and December 31, 2022, the payable balance due to affiliates was $30.3 million and $31.2 million, respectively. The majority of these transactions related to a distributorship agreement with Daikyo Seiko, LTD ("Daikyo") that allows us to purchase and re-sell Daikyo products.

Sales to affiliates were $3.3 million for the three months ended March 31, 2023, as compared to $4.0 million for the same period in 2022. As of March 31, 2023 and December 31, 2022, the receivable balance due from affiliates was $2.5 million and $2.2 million, respectively.

Please refer to Note 7, Affiliated Companies, to the consolidated financial statements in our 2022 Annual Report for additional details.

Note 8:  Debt

The following table summarizes our long-term debt obligations, net of unamortized debt issuance costs and current maturities. The interest rates shown in parentheses are as of March 31, 2023.

Credit Facility

At March 31, 2023, the borrowing capacity available under our $500.0 million multi-currency revolving credit facility, including outstanding letters of credit of $2.4 million, was $497.6 million.

Term Loan

At March 31, 2023, we had $82.6 million in borrowings under the Term Loan, of which $2.2 million was classified as current and $80.4 million was classified as long-term. Please refer to Note 9, Derivative Financial Instruments, for a discussion of the foreign currency hedge associated with the Term Loan.

Pursuant to the financial covenants in our debt agreements, we are required to maintain established interest coverage ratios and to not exceed established leverage ratios. In addition, the agreements contain other customary covenants, none of which we consider restrictive to our operations. At March 31, 2023, we were in compliance with all of our debt covenants.

Please refer to Note 10, Debt, to the consolidated financial statements in our 2022 Annual Report for additional details regarding our debt agreements.

11

Note 9:  Derivative Financial Instruments

Our ongoing business operations expose us to various risks, such as fluctuating interest rates, foreign currency exchange rates and increasing commodity prices. To manage these market risks, we periodically enter into derivative financial instruments, such as interest rate swaps, options and foreign exchange contracts for periods consistent with, and for notional amounts equal to or less than, the related underlying exposures. We do not purchase or hold any derivative financial instruments for investment or trading purposes. All derivatives are recorded in our condensed consolidated balance sheet at fair value.

Foreign Exchange Rate Risk

We have entered into forward exchange contracts, designated as fair value hedges, to manage our exposure to fluctuating foreign exchange rates on cross-currency intercompany loans. As of both March 31, 2023 and December 31, 2022, the total amount of these forward exchange contracts was Singapore Dollar (“SGD”) 601.5 million and $13.4 million.

In addition, we have entered into several foreign currency contracts, designated as cash flow hedges, for periods of up to eighteen months, intended to hedge the currency risk associated with a portion of our forecasted transactions denominated in foreign currencies. As of March 31, 2023, we had outstanding foreign currency contracts to purchase and sell certain pairs of currencies, as follows:

(in millions)		Sell
Currency	Purchase	USD	EUR
EUR	8.2	8.5	—
Yen	5,629.6	30.2	12.5
SGD	67.9	24.9	23.8

In December 2019, we entered into a cross-currency swap for $90 million, which we designated as a hedge of our net investment in Daikyo. As of March 31, 2023, the notional amount of the cross-currency swap was ¥9.0 billion ($82.6 million) and the swap termination date is December 31, 2024. Under the cross-currency swap, we receive floating interest rate payments based on USD compounded SOFR plus a margin, in return for paying floating interest rate payments based on Japanese Yen (“Yen”) Tokyo Overnight Average Rate ("TONAR") plus a margin. In addition, we receive periodic fixed payments of USD in return for paying fixed principal payments of Yen.

Commodity Price Risk

Many of our proprietary products are made from synthetic elastomers, which are derived from the petroleum refining process. We purchase the majority of our elastomers via long-term supply contracts, some of which contain clauses that provide for surcharges related to fluctuations in crude oil prices. The following economic hedges did not qualify for hedge accounting treatment since they did not meet the highly effective requirement at inception.

From November 2017 through March 2023, we purchased several series of call options for a total of 903,932 barrels of crude oil to mitigate our exposure to such oil-based surcharges and protect operating cash flows with regards to a portion of our forecasted elastomer purchases.

As of March 31, 2023, we had outstanding contracts to purchase 250,742 barrels of crude oil from March 2023 to December 2024, at a weighted-average strike price of 104.21 per barrel.

Effects of Derivative Instruments on Financial Position and Results of Operations

Please refer to Note 10, Fair Value Measurements, for the balance sheet location and fair values of our derivative instruments as of March 31, 2023 and December 31, 2022.

The following table summarizes the effects of derivative instruments designated as fair value hedges on the condensed consolidated statements of income:

	Amount of Gain (Loss) Recognized in Income for the
	Three Months Ended March 31,				Location on Statement of Income
($ in millions)	2023		2022
Fair Value Hedges:
Hedged item (intercompany loan)	$	2.5	$	(9.6)	Other expense (income)
Derivative designated as hedging instrument	(2.5)		9.6		Other expense (income)
Amount excluded from effectiveness testing	1.2		0.8		Other expense (income)
Total	$	1.2	$	0.8

We recognize in earnings the initial value of forward point components on a straight-line basis over the life of the fair value hedge. The amounts recognized in earnings, pre-tax, for forward point components for the three months ended March 31, 2023 and 2022 were $1.2 million and $0.8 million, respectively.

The following table summarizes the effects of derivative instruments designated as fair value, cash flow, and net investment hedges on other comprehensive income (“OCI”) and earnings, net of tax:

Note 10:  Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following fair value hierarchy classifies the inputs to valuation techniques used to measure fair value into one of three levels:

•Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

•Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

14

The following tables present the assets and liabilities recorded at fair value on a recurring basis:

Foreign currency contracts	1.4		—		1.4		—
	$	18.8	$	12.7	$	1.4	$	4.7

Deferred compensation assets are included within other noncurrent assets and are valued using a market approach based on quoted market prices in an active market. The fair value of our foreign currency contracts, included within other current and other noncurrent assets, as well as other current and other long-term liabilities, is valued using an income approach based on quoted forward foreign exchange rates and spot rates at the reporting date. The fair value of the cross-currency swap, included within other noncurrent assets, is valued using a market approach. Please refer to Note 9, Derivative Financial Instruments, for further discussion of our derivatives. The fair value of our commodity call options, included within other current and other noncurrent assets, is valued using a market approach. The fair value of the contingent consideration liability, within current and long-term liabilities, related to the SmartDose® technology platform (the “SmartDose® contingent consideration”) was initially determined using a probability-weighted income approach, and is revalued at each reporting date or more frequently if circumstances dictate. Changes in the fair value of this obligation are recorded as income or expense within other expense (income) in our condensed consolidated statements of income. The fair value of deferred compensation liabilities is based on quoted prices of the underlying employees’ investment selections and is included within other long-term liabilities.

15

Other Financial Instruments

We believe that the carrying amounts of our cash and cash equivalents and accounts receivable approximate their fair values due to their near-term maturities.

The estimated fair value of long-term debt is based on quoted market prices for debt issuances with similar terms and maturities and is classified as Level 2 within the fair value hierarchy. At March 31, 2023, the estimated fair value of long-term debt was $201.2 million compared to a carrying amount of $206.1 million. At December 31, 2022, the estimated fair value of long-term debt was $201.8 million and the carrying amount was $206.7 million.

Note 13: Stock-Based Compensation

The West Pharmaceutical Services, Inc. 2016 Omnibus Incentive Compensation Plan (the “2016 Plan”) provides for the granting of stock options, stock appreciation rights, restricted stock awards and performance awards to employees and non-employee directors. A committee of the Board of Directors determines the terms and conditions of awards to be granted. Vesting requirements vary by award. At March 31, 2023, there were 1,444,472 shares remaining in the 2016 Plan for future grants.

During the three months ended March 31, 2023, we granted 105,244 stock options at a weighted average exercise price of $306.68 per share based on the grant-date fair value of our stock to employees under the 2016 Plan. The weighted average grant date fair value of options granted was $108.80 per share as determined by the Black-Scholes option valuation model using the following weighted average assumptions: a risk-free interest rate of 4.1%; expected life of 5.7 years based on prior experience; stock volatility of 29.8% based on historical data; and a dividend yield of 0.3%. Stock option expense is recognized over the vesting period, net of forfeitures.

During the three months ended March 31, 2023, we granted 37,397 stock-settled performance share unit ("PSU") awards at a weighted average grant-date fair value of $306.68 per share to eligible employees. These awards are earned based on the Company's performance against pre-established targets, including annual growth rate of revenue and return on invested capital, over a specified performance period. Depending on the achievement of the targets, recipients of stock-settled PSU awards are entitled to receive a certain numbers of shares of common stock. Shares earned under PSU awards may vary from 0% to 200% of an employee's targeted award. The fair value of stock-settled PSU awards is based on the market price of our stock at the grant date and is recognized as expense over the performance period, adjusted for estimated target outcomes and net of forfeitures.

During the three months ended March 31, 2023, we granted 4,284 stock-settled restricted share unit (“RSU”) awards at a weighted average grant-date fair value of $306.68 per share to eligible employees. These awards are earned over a specified performance period. The fair value of stock-settled RSU awards is based on the market price of our stock at the grant date and is recognized as expense over the vesting period, net of forfeitures.

Stock-based compensation expense was $8.5 million and $5.5 million for the three months ended March 31, 2023 and 2022, respectively.

Net periodic benefit cost	$	0.7	$	0.8	$	(0.4)	$	(0.4)	$	0.3	$	0.4

During the three months ended March 31, 2022, we recorded a pension settlement charge of $0.6 million within other nonoperating expense (income), as we determined that normal-course lump-sum payments for our U.S. qualified defined benefit pension plan exceeded the threshold for settlement accounting under U.S. GAAP for the year.

Note 15:  Other Expense (Income)

Other expense (income) consists of:

	Three Months Ended March 31,
($ in millions)	2023		2022
Asset impairments	$	11.3	$	—
Loss (gain) on oil hedges	0.6		(2.8)
Contingent consideration	0.3		0.8
Foreign exchange transaction losses (gains)	0.9		(1.1)
Other items	(0.2)		—
Total other expense (income)	$	12.9	$	(3.1)

Restructuring and Related Charges

In December 2022, the Company approved a restructuring plan to adjust our operating cost base to better respond to the macroeconomic factors influencing our business. These changes are expected to be implemented over a period of up to twelve months from the date of approval. The plan is expected to require restructuring and related charges of approximately $25 million to $27 million, with annualized savings in the range of $22.0 million to $24.0 million.

20

The following table presents activity related to our restructuring obligations related to our 2022 restructuring plan:

($ in millions)	Severance and benefits		Asset-related charges		Total
Balance, December 31, 2022	$	10.1	$	15.3	$	25.4
Charges	—		—		—
Cash payments	(0.7)		—		(0.7)
Balance, March 31, 2023	$	9.4	$	15.3	$	24.7

Asset Impairments

During the three months ended March 31, 2023, in preparation for the sale of one of the Company’s manufacturing facilities within the Proprietary Products segment, the Company recorded an impairment expense of $9.4 million within other expense (income) and a corresponding reduction to the disposal group net assets to its fair value less cost to sell. The transaction is expected to close during the second quarter of 2023.

Contingent Consideration

Contingent consideration represents changes in the fair value of the SmartDose® contingent consideration. Please refer to Note 10, Fair Value Measurements, for additional details.

Oil Hedges

During the three months ended March 31, 2023 and 2022, we recorded a loss of $0.6 million and a gain of $2.8 million, respectively, related to oil hedges. Please refer to Note 9, Derivative Financial Instruments, for further discussion of our hedging activity.

Note 16:  Income Taxes

The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items.

The provision for income taxes was $23.6 million and $21.2 million for the three months ended March 31, 2023 and 2022, respectively, and the effective tax rate was 14.9% and 11.3%, respectively. During the three months ended March 31, 2023 and 2022, we recorded a tax benefit of $11.6 million and $8.9 million, respectively, associated with stock-based compensation. The increase in the effective tax rate is primarily due to a shift in the geographic earnings mix and a $5.9 million tax benefit recorded as a result of a state tax valuation allowance reversal in the three months ended March 31, 2022 that was not repeated in 2023. This was offset by an increase in the tax benefit related to stock-based compensation for the three months ended March 31, 2023, as compared to the same period in 2022.

Note 17:  Commitments and Contingencies

From time to time, we are involved in product liability matters and other legal proceedings and claims generally incidental to our normal business activities. We accrue for loss contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. While the outcome of current proceedings cannot be accurately predicted, we believe their ultimate resolution should not have a material adverse effect on our business, financial condition, results of operations or liquidity.

There have been no significant changes to the commitments and contingencies included in our 2022 Annual Report.

21

Note 18:  Segment Information

Our business operations are organized into two reportable segments, Proprietary Products and Contract-Manufactured Products. Our Proprietary Products reportable segment offers proprietary packaging, containment solutions and drug delivery products, along with analytical lab services and other integrated services and solutions, primarily to biologic, generic and pharmaceutical drug customers. Our Contract-Manufactured Products reportable segment serves as a fully integrated business, focused on the design, manufacture, and automated assembly of complex devices, primarily for pharmaceutical, diagnostic, and medical device customers.

The Chief Operating Decision Maker ("CODM") evaluates the performance of our segments based upon, among other things, segment net sales and operating profit. Segment operating profit excludes general corporate costs, which include executive and director compensation, stock-based compensation, certain pension and other retirement benefit costs, and other corporate facilities and administrative expenses not allocated to the segments. Also excluded are items that the CODM considers not representative of ongoing operations. Such items are referred to as other unallocated items and generally include restructuring and related charges, certain asset impairments and other specifically-identified income or expense items. The segment operating profit metric is what the CODM uses in evaluating our results of operations and the financial measure that provides a valuable insight into our overall performance and financial position.

The following table presents information about our reportable segments, reconciled to consolidated totals:

	Three Months Ended March 31,
($ in millions)	2023		2022
Net sales:
Proprietary Products	$	583.1	$	601.3
Contract-Manufactured Products	133.5		118.7
Intersegment sales elimination	—		—
Consolidated net sales	$	716.6	$	720.0

The intersegment sales elimination, which is required for the presentation of consolidated net sales, represents the elimination of components sold between our segments.

(2) During the three months ended March 31, 2023, in preparation for the sale of one of the Company’s manufacturing facilities within the Proprietary Products segment, the Company recorded an impairment expense of $9.4 million within other expense (income) and a corresponding reduction to the disposal group net assets to its fair value less cost to sell. The transaction is expected to close during the second quarter of 2023.

(3) During the three months ended March 31, 2023 and 2022, we recorded $0.2 million of amortization expense within operating profit associated with an intangible asset acquired during the second quarter of 2020.

Please refer to Note 15, Other Expense (Income), for further discussion of certain unallocated items referenced above.

ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

The following discussion is intended to further the reader’s understanding of the consolidated financial condition and results of operations of our Company. It should be read in conjunction with our condensed consolidated financial statements and accompanying notes elsewhere in this Quarterly Report on Form 10-Q (“Form 10-Q”) as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and accompanying notes included in our 2022 Annual Report. Our historical financial statements may not be indicative of our future performance. This Management’s Discussion and Analysis of Financial Condition and Results of Operations contains a number of forward-looking statements, all of which are based on our current expectations and could be affected by the uncertainties and risks discussed in Part I, Item 1A of our 2022 Annual Report and in Part II, Item 1A of this Form 10-Q.

Throughout this section, references to “Notes” refer to the notes to our condensed consolidated financial statements (unaudited) in Part I, Item 1 of this Form 10-Q, unless otherwise indicated.

23

Non-U.S. GAAP Financial Measures

For the purpose of aiding the comparison of our year-over-year results, we may refer to net sales and other financial results excluding the effects of changes in foreign currency exchange rates. Organic net sales exclude the impact from acquisitions and/or divestitures and translate the current-period reported sales of subsidiaries whose functional currency is other than USD at the applicable foreign exchange rates in effect during the comparable prior-year period. We may also refer to adjusted consolidated operating profit and adjusted consolidated operating profit margin, which exclude the effects of unallocated items. The unallocated items are not representative of ongoing operations, and generally include restructuring and related charges, certain asset impairments, and other specifically-identified income or expense items. The re-measured results excluding effects from currency translation, the impact from acquisitions and/or divestitures, and excluding the effects of unallocated items are not in conformity with U.S. Generally Accepted Accounting Principles ("GAAP") and should not be used as a substitute for the comparable U.S. GAAP financial measures. The non-U.S. GAAP financial measures are incorporated in our discussion and analysis as management uses them in evaluating our results of operations and believes that this information provides users with a valuable insight into our overall performance and financial position.

Our Operations

We are a leading global manufacturer in the design and production of technologically advanced, high-quality, integrated containment and delivery systems for injectable drugs and healthcare products. Our products include a variety of primary proprietary packaging, containment solutions, reconstitution and transfer systems, and drug delivery systems, as well as contract manufacturing, analytical lab services and integrated solutions. Our customers include leading biologic, generic, pharmaceutical, diagnostic, and medical device companies around the world. Our top priority is delivering quality products that meet the exact product specifications and quality standards customers require and expect. This focus on quality includes a commitment to excellence in manufacturing, scientific and technical expertise and management, which enables us to partner with our customers in order to deliver safe, effective drug products to patients quickly and efficiently.

Our business operations are organized into two global segments, Proprietary Products and Contract-Manufactured Products. Our Proprietary Products reportable segment offers proprietary packaging, containment solutions and drug delivery systems, along with analytical lab services and other integrated services and solutions, primarily to biologic, generic and pharmaceutical drug customers. Our Contract-Manufactured Products reportable segment serves as a fully integrated business, focused on the design, manufacture, and automated assembly of complex devices, primarily for pharmaceutical, diagnostic, and medical device customers. We also maintain collaborations to share technologies and market products with affiliates in Japan and Mexico.

Macroeconomic Factors

Through the three months ended March 31, 2023, the war between Russia and Ukraine has not had a material impact on the Company’s business, financial condition or results of operations as we do not have manufacturing operations or significant commercial relationships in either country. However, the continuation of the Russia-Ukraine military conflict and/or an escalation of the conflict beyond its current scope may further weaken the global economy and could result in additional inflationary pressures and supply chain constraints, including the unavailability and cost of energy.

During three months ended March 31, 2023 we continued to experience high costs for raw materials in both domestic and international markets.

Due to the uncertainty that exists relative to the duration and overall impact of the macroeconomic factors discussed above, our future operating performance, particularly in the short-term, may be subject to volatility. The impacts of macroeconomic conditions on our business, results of operations, financial condition and cash flows are dependent on certain factors, including those discussed in Item 1A. Risk Factors and the risk factors described in Part I, Item 1A of our 2022 Annual Report.

RESULTS OF OPERATIONS

We evaluate the performance of our segments based upon, among other things, segment net sales and operating profit. Segment operating profit excludes general corporate costs, which include executive and director compensation, stock-based compensation, certain pension and other retirement benefit costs, and other corporate facilities and administrative expenses not allocated to the segments. Also excluded are items that we consider not representative of ongoing operations. Such items are referred to as other unallocated items for which further information can be found above in the reconciliation from U.S. GAAP to non-U.S. GAAP financial measures.

Percentages in the following tables and throughout the Results of Operations section may reflect rounding adjustments.

Interest Expense, Net

The following table presents interest expense, net, by significant component:

	Three Months Ended March 31,
($ in millions)	2023		2022
Interest expense	$	3.3	$	2.7
Capitalized interest	(1.1)		(0.5)
Interest expense, net	$	2.2	$	2.2
Interest income	$	(4.8)	$	(0.3)

Interest expense, net, remained flat for the three months ended March 31, 2023, as compared to the same period in 2022.

Interest income increased by $4.5 million for the three months ended March 31, 2023, as compared to the same period in 2022, resulting from higher interest rates compared to the prior year, primarily within the US, Europe and South America.

Income Tax Expense

The provision for income taxes was $23.6 million and $21.2 million for the three months ended March 31, 2023 and 2022, respectively, and the effective tax rate was 14.9% and 11.3%, respectively. The increase in the effective tax rate is primarily due to a shift in the geographic earnings mix and a $5.9 million tax benefit recorded as a result of a state tax valuation allowance reversal in the three months ended March 31, 2022 that was not repeated in 2023. This was offset by an increase in the tax benefit related to stock-based compensation for the three months ended March 31, 2023, as compared to the same period in 2022.

Equity in Net Income of Affiliated Companies

Equity in net income of affiliated companies decreased by $1.5 million for the three months ended March 31, 2023, as compared to the same period in 2022, due to less favorable operating results at Daikyo and the Mexico affiliates.

FINANCIAL CONDITION, LIQUIDITY AND CAPITAL RESOURCES

Cash Flows

The following table presents cash flow data for the three months ended March 31:

($ in millions)	2023		2022
Net cash provided by operating activities	$	138.1	$	151.2
Net cash used in investing activities	$	(82.1)	$	(68.3)
Net cash used in financing activities	$	(71.0)	$	(172.7)

30

Net Cash Provided by Operating Activities – Net cash provided by operating activities decreased by $13.1 million for the three months ended March 31, 2023, as compared to the same period in 2022, primarily due to a decline in operating results.

Net Cash Used in Investing Activities – Net cash used in investing activities increased by $13.8 million for the three months ended March 31, 2023, as compared to the same period in 2022, primarily due to an increase in capital expenditures for additional manufacturing capacity in 2023 to meet customer demand.

Net Cash Used in Financing Activities – Net cash used in financing activities decreased by $101.7 million for the three months ended March 31, 2023, as compared to the same period in 2022, primarily due to decreases in purchases under our share repurchase program in 2023.

Liquidity and Capital Resources

The table below presents selected liquidity and capital measures:

($ in millions)	March 31, 2023		December 31, 2022
Cash and cash equivalents	$	886.3	$	894.3
Accounts receivable, net	$	513.4	$	507.4
Inventories	$	447.0	$	414.8
Accounts payable	$	233.8	$	215.4
Debt	$	208.3	$	208.9
Equity	$	2,776.2	$	2,684.9
Working capital	$	1,402.3	$	1,400.5

Cash and cash equivalents include all instruments that have maturities of ninety days or less when purchased. Working capital is defined as current assets less current liabilities.

Cash and cash equivalents – Our cash and cash equivalents balance at March 31, 2023 consisted of cash held in depository accounts with banks around the world and cash invested in high-quality, short-term investments. The cash and cash equivalents balance at March 31, 2023 included $244.4 million of cash held by subsidiaries within the U.S., and $641.9 million of cash held by subsidiaries outside of the U.S. During the three months ended March 31, 2023, we purchased 183,360 shares of our common stock under our calendar-year 2023 share repurchase program at a cost of $60.1 million, or an average price of $327.90 per share.

Working capital – Working capital at March 31, 2023 increased by $1.8 million, or 0.1%, as compared to December 31, 2022, which includes a favorable foreign currency translation impact of $8.1 million. Excluding the impact of currency exchange rates, cash and cash equivalents decreased by $15.0 million, while accounts receivable, inventories and total current liabilities increased by $2.5 million, $29.7 million and $11.9 million, respectively.

The decrease in cash and cash equivalents was due to capital expenditures and share repurchases, offset by positive operating results during the three months ended March 31, 2023. The increase in inventories that occurred during the period was to ensure we have sufficient inventory on hand to support the needs of our customers. The increase in total current liabilities was caused an increase in accounts payable and income taxes payable during the three months ended March 31, 2023.

Debt and credit facilities – The $0.6 million decrease in total debt at March 31, 2023, as compared to December 31, 2022, resulted from debt repayments under our Term Loan.

31

Our sources of liquidity include our Credit Facility. At March 31, 2023, we had no outstanding borrowings under the Credit Facility. At March 31, 2023, the borrowing capacity available under the Credit Facility, including outstanding letters of credit of $2.4 million, was $497.6 million. We do not expect any significant limitations on our ability to access this source of funds.

Pursuant to the financial covenants in our debt agreements, we are required to maintain established interest coverage ratios and not to exceed established leverage ratios. In addition, the agreements contain other customary covenants, none of which we consider restrictive to our operations. At March 31, 2023, we were in compliance with all of our debt covenants.

We believe that cash on hand and cash generated from operations, together with availability under our Credit Facility, will be adequate to address our foreseeable liquidity needs based on our current expectations of our business operations, capital expenditures and scheduled payments of debt obligations.

Commitments and Contractual Obligations

A summary of future material cash payments resulting from commitments and contractual obligations was provided in our 2022 Annual Report. During the three months ended March 31, 2023, there were no material changes outside of the ordinary course of business to our commitments and contractual obligations.

OFF-BALANCE SHEET ARRANGEMENTS

At March 31, 2023, we had no off-balance sheet financing arrangements other than unconditional purchase obligations incurred in the ordinary course of business and outstanding letters of credit related to various insurance programs, as noted in our 2022 Annual Report.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no changes to the Critical Accounting Policies and Estimates disclosed in Part II, Item 7 of our 2022 Annual Report.

NEW ACCOUNTING STANDARDS

For information on new accounting standards that were adopted during the three months ended March 31, 2023, and the impact, if any, on our financial position or results of operations, see Note 2, New Accounting Standards.

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Our disclosure and analysis in this Form 10-Q contains some forward-looking statements that are based on management’s beliefs and assumptions, current expectations, estimates and forecasts. We also provide forward-looking statements in other materials we release to the public, as well as oral forward-looking statements. Such statements provide our current expectations or forecasts of future events. They do not relate strictly to historical or current facts. We have attempted, wherever possible, to identify forward-looking statements by using words such as “plan,” “expect,” “believe,” “intend,” “will,” “estimate,” “continue” and other words of similar meaning in conjunction with, among other things, discussions of future operations and financial performance, as well as our strategy for growth, product development, market position and expenditures. All statements that address operating performance or events or developments that we expect or anticipate will occur in the future - including statements relating to sales and earnings per share growth, cash flows or uses, and statements expressing views about future operating results - are forward-looking statements.

32

Forward-looking statements are based on current expectations of future events. The forward-looking statements are, and will be, based on management’s then-current views and assumptions regarding future events and operating performance, and speak only as of their dates. Investors should realize that, if underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could vary materially from our expectations and projections. Investors are therefore cautioned not to place undue reliance on any forward-looking statements.

The following are some important factors that could cause our actual results to differ from our expectations in any forward-looking statements:

•sales demand and our ability to meet that demand;

•competition from other providers in our businesses, including customers’ in-house operations, and from lower-cost producers in emerging markets, which can impact unit volume, price and profitability;

•customers’ changing inventory requirements and manufacturing plans that alter existing orders or ordering patterns for the products we supply to them;

•interruptions or weaknesses in our supply chain, including from reasons beyond our control such as extreme weather, longer-term climate changes, natural disasters, pandemic, war, accidental damage, or unauthorized access to our or our customers’ information and systems, which could cause delivery delays or restrict the availability of raw materials, key purchased components and finished products;

•the timing, regulatory approval and commercial success of customer products that incorporate our products and systems;

•whether customers agree to incorporate our products and delivery systems with their new and existing drug products, the ultimate timing and successful commercialization of those products and systems, which involves substantial evaluations of the functional, operational, clinical and economic viability of our products, and the rate, timing and success of regulatory approval for the drug products that incorporate our components and systems;

•the timely and adequate availability of filling capacity, which is essential to conducting definitive stability trials and the timing of first commercialization of customers’ products in Crystal Zenith prefilled syringes;

•profitability, or mix, of the products sold in any reporting period, including lower-than-expected sales growth of our high-value proprietary product offerings;

•maintaining or improving production efficiencies and overhead absorption;

•dependence on third-party suppliers and partners, some of which are single-source suppliers of critical materials and products, including our Japanese partner and affiliate, Daikyo;

•the loss of key personnel or highly-skilled employees;

•the availability and cost of skilled employees required to meet increased production, managerial, research and other needs, including professional employees and persons employed under collective bargaining agreements;

•the successful and timely implementation of price increases necessary to offset rising production costs, including raw material prices, particularly petroleum-based raw materials;

•the cost and progress of development, regulatory approval and marketing of new products;

•our ability to obtain and maintain licenses in any jurisdiction in which we do business;

•the relative strength of USD in relation to other currencies, particularly the Euro, SGD, the Danish Krone, Yen, Colombian Peso, Brazilian Real, and the South Korean Won; and

33

•the potential adverse effects of global healthcare legislation on customer demand, product pricing and profitability.

This list sets forth many, but not all, of the factors that could affect our ability to achieve results described in any forward-looking statements. Investors should understand that it is not possible to predict or identify all of the factors and should not consider this list to be a complete statement of all potential risks and uncertainties. For further discussion of these and other factors, see the risk factors disclosed in Part I, Item 1A of our 2022 Annual Report as well as Part II, section 1A of this quarterly report.

Except as required by law or regulation, we undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in our exposure to market risk or the information provided in Part II, Item 7A of our 2022 Annual Report.

ITEM 4.  CONTROLS AND PROCEDURES

Disclosure controls are controls and procedures designed to reasonably ensure that information required to be disclosed in our reports filed under the Exchange Act, such as this quarterly report, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

An evaluation was performed under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934), as of the end of the period covered by this quarterly report on Form 10-Q. Based on this evaluation, our CEO and CFO have concluded that, as of March 31, 2023, our disclosure controls and procedures are effective.

Changes in Internal Controls

PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

None.

ITEM 1A.  RISK FACTORS

We are providing the disclosure below and supplementing the risk factors described in Part I, Item 1A of our 2022 Annual Report with the following risk factor. The additional risk factor identified should be read in conjunction with the risk factors described in the 2022 Annual Report and the information under the “Forward Looking Statements” in the 2022 Annual Report.

34

Unstable market and economic conditions and adverse developments with respect to financial institutions and associated liquidity risk may have serious adverse consequences on our business and financial condition.

The recent and potential future disruptions in access to bank deposits or lending commitments due to bank failure could materially and adversely affect our liquidity, our business and financial condition. Even with our continued effort to mitigate counterparty risk by working with highly liquid, well capitalized counterparties, the failure of any bank in which we deposit our funds could reduce the amount of cash we have available for our operations or delay our ability to access such funds. Any such failure may increase the possibility of a sustained deterioration of financial market liquidity, or illiquidity at clearing, cash management and/or custodial financial institutions. In the event we have a commercial relationship with a bank that has failed or is otherwise distressed, we may experience delays or other issues in meeting our financial obligations. If other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our cash and cash equivalents and investments may be threatened and could have a material adverse effect on our business and financial condition.

ITEM 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table shows information with respect to purchases of our common stock made during the three months ended March 31, 2023 by us or any of our “affiliated purchasers” as defined in Rule 10b-18(a)(3) under the Exchange Act:

Period	Total number of shares purchased (1)	Average price paid per share (1)		Total number of shares purchased as part of publicly announced plans or programs (1)	Approximate dollar value of shares that may yet be purchased under the plans or programs (1)

March 1 - 31, 2023	183,360	327.90		183,360	939,900,000
Total	183,360	$	327.90	183,360	$	939,900,000

(1)In February 2023, the Board of Directors approved a share repurchase program under which we may repurchase up to $1.0 billion in shares of common stock. The share repurchase program does not have an expiration date under which we may repurchase common stock on the open market or in privately-negotiated transactions. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting PoliciesBasis of Presentation: The condensed consolidated financial statements included in this report are unaudited and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and U.S. Securities and Exchange Commission (“SEC”) regulations. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. The condensed consolidated financial statements for the three months ended March 31, 2023, should be read in conjunction with the consolidated financial statements and notes thereto of West Pharmaceutical Services, Inc. and its majority-owned subsidiaries (which may be referred to as “West,” the “Company,” “we,” “us” or “our”) appearing in our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). The results of operations for any interim period are not necessarily indicative of results for the full year.

Accounting Standards Update and Change in Accounting Principle [Abstract]

New Accounting Standards

New Accounting Standards

Recently Adopted Standards

In September 2022, the Financial Accounting Standards Board ("FASB") issued guidance that seeks to enhance transparency around entities' use of supplier finance programs. The amendment requires the buyer in a supplier finance program to disclose information about the key terms of the program, outstanding confirmed amounts as of the end of the period, a rollforward of such amounts during each annual period, and a description of where in the financial statements outstanding amounts are presented. This guidance is effective for fiscal years beginning after December 15, 2022. We adopted this guidance as of January 1, 2023, on a prospective basis. The adoption did not have a material impact on our financial statements, as supplier finance programs are not material to the Company as of March 31, 2023.

Revenue from Contract with Customer [Abstract]

Revenue

Revenue

Our revenue results from the sale of goods or services and reflects the consideration to which we expect to be entitled in exchange for those goods or services. We record revenue based on a five-step model, in accordance with Accounting Standards Codification (“ASC”) 606. Following the identification of a contract with a customer, we identify the performance obligations (goods or services) in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize the revenue when (or as) we satisfy the performance obligations by transferring the promised goods or services to our customers. A good or service is transferred when (or as) the customer obtains control of that good or service.

The following table presents the approximate percentage of our net sales by market group:

	Three Months Ended March 31,
	2023	2022
Biologics	34 %	43 %
Generics	20 %	17 %
Pharma	27 %	24 %
Contract-Manufactured Products	19 %	16 %

Deferred income, December 31, 2022	$	(68.2)
Deferred income, March 31, 2023	(57.5)
Change in deferred income - decrease (increase)	$	10.7

Contract assets are included within other current assets and deferred income is included within other current liabilities and other long-term liabilities. During the three months ended March 31, 2023, $21.3 million of revenue was recognized that was included in deferred income at the beginning of the year.

The majority of the performance obligations within our contracts are satisfied within one year or less. Performance obligations satisfied beyond one year include those relating to a nonrefundable customer payment of $20.0 million received in June 2013 in return for the exclusive use of the SmartDose® technology platform within a specific therapeutic area. As of March 31, 2023, there was $2.8 million of deferred income related to this payment, of which $0.9 million was included in other current liabilities and $1.9 million was included in other long-term liabilities. The deferred income is being recognized as income on a straight-line basis over the remaining term of the agreement. The agreement does not include a future minimum purchase commitment from the customer.

Net Income Per Share

The following table reconciles the shares used in the calculation of basic net income per share to those used for diluted net income per share:

	Three Months Ended March 31,
(in millions)	2023		2022
Net income	$	140.0	$	173.8
Weighted average common shares outstanding	74.5		74.4
Dilutive effect of equity awards, based on the treasury stock method	1.2		1.6
Weighted average shares assuming dilution	75.7		76.0

During the three months ended March 31, 2023 and 2022, there were 0.3 million and 0.0 million shares, respectively, from stock-based compensation plans not included in the computation of diluted net income per share because their impact was antidilutive.

In February 2023, the Board of Directors approved a share repurchase program under which we may repurchase up to $1.0 billion in shares of common stock. The share repurchase program does not have an expiration date under which we may repurchase common stock on the open market or in privately-negotiated transactions. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions.

During the three months ended March 31, 2023, we purchased 183,360 shares of our common stock under the program at a cost of $60.1 million, or an average price of $327.90 per share. During the three months ended March 31, 2022, we purchased 390,000 shares of our common stock under the program at a cost of $147.1 million, or an average price of $377.23 per share.

Leases [Abstract]

Leases

LeasesA lease exists when a contract conveys to the customer the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. The definition of a lease embodies two conditions: 1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and equipment); and 2) the customer has the right to control the use of the identified asset. Lease payments included in the measurement of the operating lease right-of-use assets and lease liabilities are comprised of fixed payments (including in-substance fixed payments), variable payments that depend on an index or rate, and the exercise price of a lessee option to purchase the underlying asset if the lessee is reasonably certain to exercise.

The components of lease expense were as follows:

	Three Months Ended March 31,
($ in millions)	2023		2022
Operating lease cost	$	5.9	$	3.3

Equity Method Investments and Joint Ventures [Abstract]

Affiliated Companies

Affiliated CompaniesAt March 31, 2023 and December 31, 2022, the aggregate carrying amount of our investment in affiliated companies that are accounted for under the equity method was $200.9 million and $197.0 million, respectively, and the aggregate carrying amount of our investment in affiliated companies that are not accounted for under the equity method was $7.9 million and $7.9 million at March 31, 2023 and December 31, 2022, respectively. We have elected to record these investments, for which fair value was not readily determinable, at cost, less impairment, adjusted for subsequent observable price changes. We test these investments for impairment whenever circumstances indicate that the carrying value of the investments may not be recoverable.

Our purchases from, and royalty payments made to, affiliates totaled $44.2 million for the three months ended March 31, 2023, as compared to $58.5 million for the same period in 2022. As of March 31, 2023 and December 31, 2022, the payable balance due to affiliates was $30.3 million and $31.2 million, respectively. The majority of these transactions related to a distributorship agreement with Daikyo Seiko, LTD ("Daikyo") that allows us to purchase and re-sell Daikyo products.

Sales to affiliates were $3.3 million for the three months ended March 31, 2023, as compared to $4.0 million for the same period in 2022. As of March 31, 2023 and December 31, 2022, the receivable balance due from affiliates was $2.5 million and $2.2 million, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Derivative Financial Instruments

Our ongoing business operations expose us to various risks, such as fluctuating interest rates, foreign currency exchange rates and increasing commodity prices. To manage these market risks, we periodically enter into derivative financial instruments, such as interest rate swaps, options and foreign exchange contracts for periods consistent with, and for notional amounts equal to or less than, the related underlying exposures. We do not purchase or hold any derivative financial instruments for investment or trading purposes. All derivatives are recorded in our condensed consolidated balance sheet at fair value.

Foreign Exchange Rate Risk

We have entered into forward exchange contracts, designated as fair value hedges, to manage our exposure to fluctuating foreign exchange rates on cross-currency intercompany loans. As of both March 31, 2023 and December 31, 2022, the total amount of these forward exchange contracts was Singapore Dollar (“SGD”) 601.5 million and $13.4 million.

In addition, we have entered into several foreign currency contracts, designated as cash flow hedges, for periods of up to eighteen months, intended to hedge the currency risk associated with a portion of our forecasted transactions denominated in foreign currencies. As of March 31, 2023, we had outstanding foreign currency contracts to purchase and sell certain pairs of currencies, as follows:

(in millions)		Sell
Currency	Purchase	USD	EUR
EUR	8.2	8.5	—
Yen	5,629.6	30.2	12.5
SGD	67.9	24.9	23.8

In December 2019, we entered into a cross-currency swap for $90 million, which we designated as a hedge of our net investment in Daikyo. As of March 31, 2023, the notional amount of the cross-currency swap was ¥9.0 billion ($82.6 million) and the swap termination date is December 31, 2024. Under the cross-currency swap, we receive floating interest rate payments based on USD compounded SOFR plus a margin, in return for paying floating interest rate payments based on Japanese Yen (“Yen”) Tokyo Overnight Average Rate ("TONAR") plus a margin. In addition, we receive periodic fixed payments of USD in return for paying fixed principal payments of Yen.

Commodity Price Risk

Many of our proprietary products are made from synthetic elastomers, which are derived from the petroleum refining process. We purchase the majority of our elastomers via long-term supply contracts, some of which contain clauses that provide for surcharges related to fluctuations in crude oil prices. The following economic hedges did not qualify for hedge accounting treatment since they did not meet the highly effective requirement at inception.

From November 2017 through March 2023, we purchased several series of call options for a total of 903,932 barrels of crude oil to mitigate our exposure to such oil-based surcharges and protect operating cash flows with regards to a portion of our forecasted elastomer purchases.

As of March 31, 2023, we had outstanding contracts to purchase 250,742 barrels of crude oil from March 2023 to December 2024, at a weighted-average strike price of 104.21 per barrel.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The following fair value hierarchy classifies the inputs to valuation techniques used to measure fair value into one of three levels:

•Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities.

•Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

•Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

The following tables present the assets and liabilities recorded at fair value on a recurring basis:

	Balance at		Basis of Fair Value Measurements
($ in millions)	March 31, 2023		Level 1		Level 2		Level 3

Foreign currency contracts	1.4		—		1.4		—
	$	18.8	$	12.7	$	1.4	$	4.7

Deferred compensation assets are included within other noncurrent assets and are valued using a market approach based on quoted market prices in an active market. The fair value of our foreign currency contracts, included within other current and other noncurrent assets, as well as other current and other long-term liabilities, is valued using an income approach based on quoted forward foreign exchange rates and spot rates at the reporting date. The fair value of the cross-currency swap, included within other noncurrent assets, is valued using a market approach. Please refer to Note 9, Derivative Financial Instruments, for further discussion of our derivatives. The fair value of our commodity call options, included within other current and other noncurrent assets, is valued using a market approach. The fair value of the contingent consideration liability, within current and long-term liabilities, related to the SmartDose® technology platform (the “SmartDose® contingent consideration”) was initially determined using a probability-weighted income approach, and is revalued at each reporting date or more frequently if circumstances dictate. Changes in the fair value of this obligation are recorded as income or expense within other expense (income) in our condensed consolidated statements of income. The fair value of deferred compensation liabilities is based on quoted prices of the underlying employees’ investment selections and is included within other long-term liabilities.

Other Financial Instruments

We believe that the carrying amounts of our cash and cash equivalents and accounts receivable approximate their fair values due to their near-term maturities.

The estimated fair value of long-term debt is based on quoted market prices for debt issuances with similar terms and maturities and is classified as Level 2 within the fair value hierarchy. At March 31, 2023, the estimated fair value of long-term debt was $201.2 million compared to a carrying amount of $206.1 million. At December 31, 2022, the estimated fair value of long-term debt was $201.8 million and the carrying amount was $206.7 million.

Stock-Based Compensation

Share-Based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The West Pharmaceutical Services, Inc. 2016 Omnibus Incentive Compensation Plan (the “2016 Plan”) provides for the granting of stock options, stock appreciation rights, restricted stock awards and performance awards to employees and non-employee directors. A committee of the Board of Directors determines the terms and conditions of awards to be granted. Vesting requirements vary by award. At March 31, 2023, there were 1,444,472 shares remaining in the 2016 Plan for future grants.

During the three months ended March 31, 2023, we granted 105,244 stock options at a weighted average exercise price of $306.68 per share based on the grant-date fair value of our stock to employees under the 2016 Plan. The weighted average grant date fair value of options granted was $108.80 per share as determined by the Black-Scholes option valuation model using the following weighted average assumptions: a risk-free interest rate of 4.1%; expected life of 5.7 years based on prior experience; stock volatility of 29.8% based on historical data; and a dividend yield of 0.3%. Stock option expense is recognized over the vesting period, net of forfeitures.

During the three months ended March 31, 2023, we granted 37,397 stock-settled performance share unit ("PSU") awards at a weighted average grant-date fair value of $306.68 per share to eligible employees. These awards are earned based on the Company's performance against pre-established targets, including annual growth rate of revenue and return on invested capital, over a specified performance period. Depending on the achievement of the targets, recipients of stock-settled PSU awards are entitled to receive a certain numbers of shares of common stock. Shares earned under PSU awards may vary from 0% to 200% of an employee's targeted award. The fair value of stock-settled PSU awards is based on the market price of our stock at the grant date and is recognized as expense over the performance period, adjusted for estimated target outcomes and net of forfeitures.

During the three months ended March 31, 2023, we granted 4,284 stock-settled restricted share unit (“RSU”) awards at a weighted average grant-date fair value of $306.68 per share to eligible employees. These awards are earned over a specified performance period. The fair value of stock-settled RSU awards is based on the market price of our stock at the grant date and is recognized as expense over the vesting period, net of forfeitures.

Stock-based compensation expense was $8.5 million and $5.5 million for the three months ended March 31, 2023 and 2022, respectively.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The tax provision for interim periods is determined using the estimated annual effective consolidated tax rate, based on the current estimate of full-year earnings before taxes, adjusted for the impact of discrete quarterly items.

The provision for income taxes was $23.6 million and $21.2 million for the three months ended March 31, 2023 and 2022, respectively, and the effective tax rate was 14.9% and 11.3%, respectively. During the three months ended March 31, 2023 and 2022, we recorded a tax benefit of $11.6 million and $8.9 million, respectively, associated with stock-based compensation. The increase in the effective tax rate is primarily due to a shift in the geographic earnings mix and a $5.9 million tax benefit recorded as a result of a state tax valuation allowance reversal in the three months ended March 31, 2022 that was not repeated in 2023. This was offset by an increase in the tax benefit related to stock-based compensation for the three months ended March 31, 2023, as compared to the same period in 2022.

Commitments and Contingencies

Commitments and Contingencies

From time to time, we are involved in product liability matters and other legal proceedings and claims generally incidental to our normal business activities. We accrue for loss contingencies when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. While the outcome of current proceedings cannot be accurately predicted, we believe their ultimate resolution should not have a material adverse effect on our business, financial condition, results of operations or liquidity.

There have been no significant changes to the commitments and contingencies included in our 2022 Annual Report.

Segment Reporting [Abstract]

Segment Information

Segment Information

Our business operations are organized into two reportable segments, Proprietary Products and Contract-Manufactured Products. Our Proprietary Products reportable segment offers proprietary packaging, containment solutions and drug delivery products, along with analytical lab services and other integrated services and solutions, primarily to biologic, generic and pharmaceutical drug customers. Our Contract-Manufactured Products reportable segment serves as a fully integrated business, focused on the design, manufacture, and automated assembly of complex devices, primarily for pharmaceutical, diagnostic, and medical device customers.

The Chief Operating Decision Maker ("CODM") evaluates the performance of our segments based upon, among other things, segment net sales and operating profit. Segment operating profit excludes general corporate costs, which include executive and director compensation, stock-based compensation, certain pension and other retirement benefit costs, and other corporate facilities and administrative expenses not allocated to the segments. Also excluded are items that the CODM considers not representative of ongoing operations. Such items are referred to as other unallocated items and generally include restructuring and related charges, certain asset impairments and other specifically-identified income or expense items. The segment operating profit metric is what the CODM uses in evaluating our results of operations and the financial measure that provides a valuable insight into our overall performance and financial position.

The following table presents information about our reportable segments, reconciled to consolidated totals:

	Three Months Ended March 31,
($ in millions)	2023		2022
Net sales:
Proprietary Products	$	583.1	$	601.3
Contract-Manufactured Products	133.5		118.7
Intersegment sales elimination	—		—
Consolidated net sales	$	716.6	$	720.0

The intersegment sales elimination, which is required for the presentation of consolidated net sales, represents the elimination of components sold between our segments.

The following table provides summarized financial information for our segments:

	Three Months Ended March 31,

(1) Corporate general costs includes executive and director compensation, certain pension and other retirement benefit costs, and other corporate facilities and administrative expenses not allocated to the segments.

(2) During the three months ended March 31, 2023, in preparation for the sale of one of the Company’s manufacturing facilities within the Proprietary Products segment, the Company recorded an impairment expense of $9.4 million within other expense (income) and a corresponding reduction to the disposal group net assets to its fair value less cost to sell. The transaction is expected to close during the second quarter of 2023.

(3) During the three months ended March 31, 2023 and 2022, we recorded $0.2 million of amortization expense within operating profit associated with an intangible asset acquired during the second quarter of 2020.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation: The condensed consolidated financial statements included in this report are unaudited and have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and U.S. Securities and Exchange Commission (“SEC”) regulations. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, cash flows and the change in equity for the periods presented. The condensed consolidated financial statements for the three months ended March 31, 2023, should be read in conjunction with the consolidated financial statements and notes thereto of West Pharmaceutical Services, Inc. and its majority-owned subsidiaries (which may be referred to as “West,” the “Company,” “we,” “us” or “our”) appearing in our Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). The results of operations for any interim period are not necessarily indicative of results for the full year.

Recently Adopted Standards

Recently Adopted Standards

In September 2022, the Financial Accounting Standards Board ("FASB") issued guidance that seeks to enhance transparency around entities' use of supplier finance programs. The amendment requires the buyer in a supplier finance program to disclose information about the key terms of the program, outstanding confirmed amounts as of the end of the period, a rollforward of such amounts during each annual period, and a description of where in the financial statements outstanding amounts are presented. This guidance is effective for fiscal years beginning after December 15, 2022. We adopted this guidance as of January 1, 2023, on a prospective basis. The adoption did not have a material impact on our financial statements, as supplier finance programs are not material to the Company as of March 31, 2023.
