Exton, PA, February 18, 2021 – West Pharmaceutical Services, Inc. (NYSE: WST) today announced its financial results for the fourth-quarter, full-year 2020 and introduced full-year 2021 financial guidance.

Fourth-Quarter and Full-Year 2020 Summary (comparisons to prior-year period)

•Fourth-quarter 2020 net sales of $580.2 million grew 23.3%; organic sales growth was 19.8%. Full-year 2020 net sales of $2.147 billion grew 16.7%; organic sales growth was 16.3%.

•Fourth-quarter 2020 adjusted-diluted EPS of $1.34 increased 63.4%. Full-year 2020 adjusted-diluted EPS of $4.76 increased 46.9%.

•Company is introducing full-year 2021 financial guidance of net sales in a range of $2.500 billion to $2.525 billion and reported-diluted EPS in a range of $6.00 to $6.15.

“Adjusted-diluted EPS” and “organic sales growth” are Non-U.S. GAAP measurements. See discussion under the heading “Non-U.S. GAAP Financial Measures” in this release.

“We had a successful 2020 with tremendous execution, dedication and resiliency of our team and, most importantly, the trust of our customers across the globe. I am proud that we finished the year with record full-year net sales, organic sales growth and operating profit margin. Fourth quarter results were robust, led by strong growth in our Biologics and Generics market units. In addition, we experienced an acceleration in COVID-19-associated sales of high-value product (HVP) components used for vaccines and therapeutics,” said Eric M. Green, President and Chief Executive Officer.

Mr. Green concluded, “As we look ahead, we believe there is strong momentum in our base business and uptake of our HVP components and devices. We will continue to operate with excellence and a sense of urgency to maintain the supply of life-saving solutions that our customers, and ultimately patients, rely upon during these challenging times.”

Proprietary Products Segment

In the fourth-quarter 2020, net sales grew by 28.7% to $454.1 million. Organic sales growth was 25.1%, with currency translation increasing sales growth by 360 basis points. HVP components and devices represented over 65% of segment sales and generated double-digit organic sales growth.

Our Biologics market unit had strong double-digit organic sales growth, led by Flurotec®, Westar®, Daikyo® and NovaPure® components. Our Generics market unit posted double-digit organic sales growth, led by Flurotec and Westar components. Our Pharma market unit had low single-digit organic sales growth, led by Westar and Flurotec components and Crystal Zenith® containers.

In the full-year 2020, net sales grew 17.9% to $1.649 billion. Organic sales growth was 17.6%, with currency translation increasing sales growth by 20 basis points. HVP components and devices represented 66% of segment sales and generated double-digit organic sales growth.

Contract-Manufactured Products Segment

In the fourth-quarter 2020, net sales grew by 7.0% to $126.1 million. Organic sales growth was 4.1%, with currency translation increasing sales growth by 290 basis points. Segment performance was led by strong sales of healthcare-related injection and diagnostic devices.

In the full-year 2020, net sales grew by 12.9% to $498.6 million. Organic sales growth was 12.1%, with currency translation increasing sales growth by 80 basis points.

Full-Year 2020 Financial Highlights

Operating cash flow was $472.5 million, an increase of 28.7%. Capital expenditures were $174.4 million. Free cash flow (operating cash flow minus capital expenditures) was $298.1 million, an increase of 23.8%.

Full-Year 2021 Financial Guidance

Full-year 2021 net sales are expected to be in a range of $2.500 billion to $2.525 billion.

◦Organic sales growth is expected to be in a range of 13% to 14%.

◦Net sales guidance includes an estimated full-year 2021 benefit of $75 million based on current foreign exchange rates.

Full-year 2021 reported-diluted EPS is expected to be in a range of $6.00 to $6.15.

◦Full-year reported-diluted EPS guidance range includes an estimated benefit of approximately $0.23 based on current foreign currency exchange rates.

◦This reported-diluted EPS guidance range assumes a full-year 2021 tax rate of 23%, which does not include potential tax benefits from stock-based compensation. As in prior years, we are not including potential 2021 tax benefits from stock-based compensation, as they are out of the Company's control. Any tax benefits associated with stock-based compensation that we receive in 2021 would provide a positive adjustment to our full-year EPS guidance.

◦Full-year 2021 capital spending is expected to be in a range of $230 million to $240 million. This includes incremental capital spending to support capacity expansions at existing HVP facilities to produce components to be used with treatments and vaccines related to COVID-19.

Forward-Looking Statements

Certain forward-looking statements appear in this release and include such words as “believe,” “continue,” “maintain,” “expected,” “to be,” “includes,” “estimated,” “assumes,” “potential,” “would provide,” and other similar terminology. These statements reflect management’s current expectations regarding future events and operating performance and speak only as of the date of this release. There is no certainty that actual results will be achieved in-line with current expectations. These forward-looking statements involve a number of risks and uncertainties. The following are some of the factors that could cause our actual results to differ materially from those expressed in or underlying our forward-looking statements: the duration and severity of the global COVID-19 pandemic, including prevailing economic conditions and general uncertainties relating thereto that may be unknown and unforeseeable; customers’ changing inventory requirements and manufacturing plans and customer decisions to move forward with our new products and product categories, including any re-prioritization of product needs due to COVID-19; other potential impacts from COVID-19, including interruptions or weaknesses in our supply chain, illness in our workforce and access to transport for our products; average profitability, or mix, of the products we sell; dependence on third-party suppliers and partners; increased raw material costs; fluctuations in currency exchange; and the ability to meet development milestones with key customers. This list of important factors is not all inclusive. For a description of certain additional factors that could cause the Company’s future results to differ from those expressed in any such forward-looking statements, see Part I Item 1A and Part II Item 1A, entitled “Risk Factors,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 and Quarterly Report on Form 10-Q for the period ended September 30, 2020, respectively.

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.

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 the U.S. Dollar at the applicable foreign exchange rates in effect during the comparable prior-year period. We may also refer to financial results excluding the effects of unallocated items. The re-measured results excluding effects from currency translation and excluding the effects of unallocated items are not in conformity with U.S. generally accepted accounting principles (“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 into our discussion and analysis as management uses them in evaluating our results of operations and believes that this information provides users a valuable insight into our overall performance and financial position. A reconciliation of these adjusted Non-U.S. GAAP measures to the comparable U.S. GAAP financial measures is included in the accompanying tables.

Such statements include, but are not limited to, statements about product development and operational performance. Each of these statements is based on preliminary information, and actual results could differ from any preliminary estimates. We caution investors that the risk factors listed under “Cautionary Statement” in our press releases, as well as those set forth under the caption "Risk Factors" in our most recent Annual Report on Form 10-K as filed with the Securities and Exchange Commission and as revised or supplemented by our quarterly reports on Form 10-Q, could cause our actual results to differ materially from those estimated or predicted in the forward-looking statements. You should evaluate any statement in light of these important factors. 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. Non-U.S. GAAP Financial Measures Certain financial measures included in these presentation materials, or which may be referred to in management’s discussion of the Company’s results and outlook, have not been calculated in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), and therefore are referred to as non- U.S. GAAP financial measures.

Green President and Chief Executive Officer West Pharmaceutical Services, Inc. “We had a successful 2020 with tremendous execution, dedication and resiliency of our team and, most importantly, the trust of our customers across the globe. I am proud that we finished the year with record full-year net sales, organic sales growth and operating profit margin. Fourth quarter results were robust, led by strong growth in our Biologics and Generics market units. In addition, we experienced an acceleration in COVID-19-associated sales of high-value product (HVP) components used for vaccines and therapeutics. As we look ahead, we believe there is strong momentum in our base business and uptake of our HVP components and devices. We will continue to operate with excellence and a sense of urgency to maintain the supply of life-saving solutions that our customers, and ultimately patients, rely upon during these challenging times.”

Eric M. Green President and Chief Executive Officer Bernard J. Birkett Senior Vice President and Chief Financial Officer Quintin Lai VP, Corporate Development, Strategy & Investor Relations Q & A

The non-U.S. GAAP financial measures are incorporated into our discussion and analysis as management uses them in evaluating our results of operations and believes that this information provides users a valuable insight into our overall performance and financial position. A reconciliation of these adjusted Non-U.S. GAAP financial measures to the comparable U.S. GAAP financial measures is included in the accompanying tables. 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 the U.S. Dollar at the applicable foreign exchange rates in effect during the comparable prior-year period. We may also refer to financial results excluding the effects of unallocated items. The re-measured results excluding effects from currency translation, the impact from acquisitions and/or divestitures, and 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.

Reconciliation of Reported-Diluted EPS Guidance to Adjusted-Diluted EPS Guidance 2020 Actual 2021 Guidance % Change Reported-diluted EPS (U.S. GAAP) $4.57 $6.00 to $6.15 31% to 35% Pension settlement 0.04 - Cost investment impairment 0.03 - Restructuring and severance related charges 0.07 - Amortization of acquisition-related intangible assets 0.05 0.03 Adjusted-diluted EPS (Non-U.S. GAAP) (1) $4.76 $6.03 to $6.18 27% to 30% (1) See “Full-year 2020 Financial Guidance” and “Non-U.S. GAAP Financial Measures” in today’s press release for additional information regarding adjusted-diluted EPS. In 2020, tax benefits associated with stock-based compensation increased adjusted-diluted EPS by $0.27. We have opted not to forecast 2021 tax benefits from stock-based compensation in upcoming quarters, as they are out of the Company’s control. Instead, we recognize the benefits as they occur. In the First-Quarter, Second-Quarter, Third- Quarter, and Fourth-Quarter 2020, tax benefits associated with stock-based compensation increased adjusted-diluted EPS by $0.07, $0.09, $0.02, and $0.09, respectively. Any future tax benefits associated with stock-based compensation that we receive in 2021 would provide a positive adjustment to our full-year EPS guidance.
