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, 2021, 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, 2020 (the “2020 Annual Report”). The results of operations for any interim period are not necessarily indicative of results for the full year.
West has been actively monitoring the novel coronavirus (“COVID-19”) situation and its impact globally. Our production facilities continue to operate as they had prior to the COVID-19 pandemic, other than for enhanced safety measures intended to prevent the spread of the virus and higher levels of production at certain plant locations to meet additional customer demand. The remote working arrangements and travel restrictions imposed by various governments had limited impact on our ability to maintain operations, as our manufacturing operations have generally been exempted from stay-at-home orders.
Note 2: New Accounting Standards
Standards Issued Not Yet Adopted
In March 2020, the FASB issued guidance which provides optional expedients and exceptions to address the impact of reference rate reform where contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate need to be discontinued. This guidance was effective upon issuance and generally can be applied through December 31, 2022. We are currently evaluat i ng the impact to our financial statements, the transition, and disclosure requirements of this guidance.
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 ASC Topic 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 decrease in the deferred income balance is primarily due to the revenue recognition associated with the capacity reservation agreements, which is to be recognized over the next 1 to 2 years.

Table of Contents
During the three months ended March 31, 2021, $17.4 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. 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, 2021, there was $4.5 million of unearned income related to this payment, of which $0.9 million was included in other current liabilities and $3.6 million was included in other long-term liabilities. The unearned 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.
Voluntary Recall
On January 24, 2019, we issued a voluntary recall of our Vial2Bag® product line due to reports of potential unpredictable or variable dosing under certain conditions. On October 21, 2020 we received market clearance from the Food and Drug Administration ("FDA") for our Vial2BagAdvancedTM 20mm Admixture Device and the product is back on the market.
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, |  |

Net income | $ | 151.2 |  |  | $ | 74.3 |  |  |  |  |
Weighted average common shares outstanding | 73.9 |  |  | 73.9 |  |  |  |  |
Dilutive effect of equity awards, based on the treasury stock method | 1.9 |  |  | 1.6 |  |  |  |  |
Weighted average shares assuming dilution | 75.8 |  |  | 75.5 |  |  |  |  |

During the three months ended March 31, 2021 and 2020, there were 0.1 million and 0.1 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 December 2020, we announced a share repurchase program for calendar-year 2021 authorizing the repurchase of up to 631,000 shares of our common stock from time to time on the open market or in privately-negotiated transactions as permitted under Exchange Act Rule 10b-18. The number of shares to be repurchased and the timing of such transactions will depend on a variety of factors, including market conditions. This share repurchase program is expected to be completed by December 31, 2021.
During the three months ended March 31, 2021, we purchased 479,000 shares of our common stock under the program at a cost of $137.1 million, or an average price of $286.23 per share.

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) | 2021 |  | 2020 |  |  |  |
Operating lease cost | $ | 3.1 |  |  | $ | 3.1 |  |  |  |  |

Note 7: Affiliated Companies
At March 31, 2021 and December 31, 2020, the aggregate carrying amount of our investment in affiliated companies that are accounted for under the equity method was $201.3 million and $201.9 million, respectively, and the aggregate carrying amount of our investment in affiliated companies that are not accounted for under the equity method was $10.6 million and $12.8 million at March 31, 2021 and December 31, 2020, 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 $38.0 million for the three months ended March 31, 2021, as compared to $32.5 million for the same period in 2020. As of March 31, 2021 and December 31, 2020, the payable balance due to affiliates was $18.9 million and $33.6 million, respectively. The majority of these transactions related to a distributorship agreement with Daikyo that allows us to purchase and re-sell Daikyo products.
Sales to affiliates were $2.9 million for the three months ended March 31, 2021, as compared to $2.2 million for the same period in 2020. As of March 31, 2021 and December 31, 2020, the receivable balance due from affiliates was $1.7 million and $1.4 million, respectively.

Credit Agreement - Credit Facility
At March 31, 2021, the borrowing capacity available under our $300.0 million multi-currency revolving credit facility (the “Credit Facility”), including outstanding letters of credit of $2.5 million, was $297.5 million.
Credit Agreement Amendment - Term Loan
At March 31, 2021, we had $87.2 million in borrowings under the Term Loan, of which $2.3 million was classified as current and $84.9 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.
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, 2021 and December 31, 2020, the total amount of these forward exchange contracts was Singapore Dollar (“SGD”) 601.5 million and $13.4 million.

Table of Contents
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, 2021, we had outstanding foreign currency contracts to purchase and sell certain pairs of currencies, as follows:

(in millions) |  |  | Sell
Currency | Purchase |  | USD | Euro
USD | 50.3 |  |  | — |  | 42.7 |
Yen | 8,666.4 |  |  | 36.3 |  | 38.9 |
SGD | 65.0 |  |  | 37.4 |  | 8.9 |
EUR | 37.8 |  |  | 46.1 |  | — |

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. The notional amount of the cross-currency swap is ¥9.5 billion ($87.2 million) and the swap termination date is December 31, 2024. Under the cross-currency swap, we receive floating interest rate payments based on three-month U.S. Dollar (“USD”) LIBOR plus a margin, in return for paying floating interest rate payments based on three-month Japanese Yen (“Yen”) LIBOR plus a margin.
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 2021, we purchased several series of call options for a total of 509,456 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, 2021, we had outstanding contracts to purchase 148,326 barrels of crude oil from April 2021 to September 2022, at a weighted-average strike price of $60.99 per barrel.

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.

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 our commodity call options, included within other current and other noncurrent assets, is valued using a market approach. The fair value of our contingent consideration, included within other current and other long-term liabilities, is discussed further in the section related to Level 3 fair value measurements. 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. 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.

Level 3 Fair Value Measurements
The fair value of the contingent consideration liability 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 significant unobservable inputs used in the fair value measurement of the SmartDose contingent consideration are the sales projections, the probability of success factors, and the discount rate. Significant increases or decreases in any of those inputs in isolation would result in a significantly lower or higher fair value measurement. Sales projections were derived using upside, base and downside forecasted cases for each partnership and applying probability-weighted scenarios of 10%, 50% and 40% to the three cases, respectively, to reflect the likelihood of West meeting the estimated sales projection targets. The probability of success factors included the probabilities of successful FDA approval for each partnership drug, which was estimated in a range of 19% to 100% based on the development phase of each respective drug, and the probability of the successful execution of supply agreements with each partnership, which was estimated in the range of 25% to 100% based on historical, current, and future supply agreements with the respective partnerships. The fair value of this liability utilized a risk-adjusted discount rate of 19% to present value the cash flows. The discount rate is calculated by determining the after-tax required returns on debt and equity and weighting each return by the respective percent of debt and equity to total capital. Key inputs for the discount rate include the risk-free rate on the 20-Year United States Treasury maturity, equity risk premium, company-specific risk premium, pre-tax cost of debt, and U.S. tax rate, among others. As development and commercialization of the SmartDose technology platform progresses, we may need to update the sales projections, the probability of success factors, and the discount rate used. This could result in an increase or decrease to the SmartDose contingent consideration.
The following table provides a summary of changes in our Level 3 fair value measurements:

| ($ in millions)
Balance, December 31, 2019 | $ | 3.3 |
Increase in fair value recorded in earnings | 1.2 |
Payments | (0.9) |

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, 2021, the estimated fair value of long-term debt was $264.6 million compared to a carrying amount of $252.3 million. At December 31, 2020, the estimated fair value of long-term debt was $265.7 million and the carrying amount was $252.9 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, 2021, there were 2,659,134 shares remaining in the 2016 Plan for future grants.
During the three months ended March 31, 2021, we granted 155,344 stock options at a weighted average exercise price of $274.29 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 $63.00 per share as determined by the Black-Scholes option valuation model using the following weighted average assumptions: a risk-free interest rate of 0.7%; expected life of 5.6 years based on prior experience; stock volatility of 23.9% 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, 2021, we granted 4,167 stock-settled restricted share unit (“RSU”) awards at a weighted average grant-date fair value of $274.29 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 $5.9 million and $5.4 million for the three months ended March 31, 2021 and 2020, respectively.

Restructuring and Related Charges
In July 2020, our Board of Directors approved a restructuring plan designed to optimize certain organizational structures within the Company to better support our continued growth and business priorities. These changes are expected to be implemented over a period of up to twenty-four months from the date of approval. The plan is expected to require restructuring and related charges of approximately $15 million to $17 million. Since its approval, we recorded a net pre-tax amount equal to $5.8 million in restructuring and related charges associated with this plan.
The following table presents activity related to our restructuring obligations related to our 2020 restructuring plan:

In February 2018, our Board of Directors approved a restructuring plan designed to realign our manufacturing capacity with demand. These changes were expected to be implemented over a period of up to twenty-four months from the date of approval. The plan was expected to require restructuring and related charges of approximately $16 million. Since its approval, we have recorded $13.7 million in restructuring and related charges associated with this plan. The plan is now considered complete.

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.
Other Items
During the three months ended March 31, 2021, we recorded an impairment charge of $2.2 million for one of the Company's cost investments.
During the three months ended March 31, 2021 and 2020, we recorded development income of $0.2 million and $0.2 million, respectively, related 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. Please refer to Note 3, Revenue, for additional information.
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 $28.7 million and $15.0 million for the three months ended March 31, 2021 and 2020, respectively, and the effective tax rate was 16.4% and 17.4%, respectively. During the three months ended March 31, 2021 and 2020, we recorded a tax benefit of $11.1 million and $5.1 million, respectively, associated with stock-based compensation, which contributed to the decline in the effective tax rate.
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 2020 Annual Report.
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 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.

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 2020 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 2020 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.
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. 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 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 the leading biologic, generic, pharmaceutical, diagnostic, and additional medical device companies in 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 reportable segments, Proprietary Products and Contract-Manufactured Products. Our Proprietary Products reportable segment offers proprietary packaging, containment 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. We also maintain collaborations to share technologies and market products with affiliates in Japan and Mexico.

Impact of COVID-19
West has been actively monitoring the COVID-19 situation and its impact globally. Our primary objectives have remained the same throughout the pandemic: to support the safety of our team members and their families and continue to support patients around the world. Our production facilities continue to operate as they had prior to the COVID-19 pandemic, other than for enhanced safety measures intended to prevent the spread of the virus and higher levels of production at certain plant locations to meet additional customer demand. Our capital and financial resources, including overall liquidity, remain strong. The remote working arrangements and travel restrictions imposed by various governments had limited impact on our ability to maintain operations, as our manufacturing operations have generally been exempted from stay-at-home orders. However, we cannot predict the impact of the progression of the COVID-19 pandemic on future results due to a variety of factors, including the continued good health of our employees, the ability of suppliers to continue to operate and deliver, the ability of West and its customers to maintain operations, continued access to transportation resources, the changing needs and priorities of customers, any further government and/or public actions taken in response to the pandemic and ultimately the length of the pandemic. We will continue to closely monitor the COVID-19 pandemic in order to ensure the safety of our people and our ability to serve our customers and patients worldwide.

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.
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.
33

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

Table of Contents
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 2020 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.
