•Company is introducing full-year 2022 financial guidance of net sales in a range of $3.050 billion to $3.075 billion and reported-diluted EPS in a range of $9.20 to $9.35.

“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 2021 with record organic sales growth and gross operating margin expansion,” said Eric M. Green, President and Chief Executive Officer. “Our performance was fueled by execution across our Proprietary market units and all geographies as we serve to improve patients’ lives. Our business generated strong double-digit organic sales growth in the fourth-quarter and full-year 2021, led by sales of high-value products (HVP).”

Mr. Green added, “Our incredible West team has continued to meet the ongoing challenges of the pandemic and deliver on the strong momentum in customer demand. Proudly, we enter the year with a strong outlook in our Proprietary Products segment and continued HVP growth. Looking ahead, our capital investments and recently announced collaboration with Corning will continue to drive future growth and innovation, as we are well positioned for success in 2022 and beyond.”

Proprietary Products Segment

In the fourth-quarter 2021, net sales grew by 34.2% to $609.3 million. Organic sales growth was 36.8%, with currency translation decreasing sales growth by 260 basis points. HVP components and devices represented approximately 74% of segment sales and generated strong double-digit organic sales growth.

All three market units had double-digit organic sales growth. The Biologics market unit had strong double-digit organic sales growth, led by NovaPure® and Westar® components. The Generics and Pharma market units' organic sales growth was led by FluroTec® and Westar components.

In the full-year 2021, net sales grew 40.6% to $2.317 billion. Organic sales growth was 37.8%, with currency translation increasing sales growth by 280 basis points. HVP components and devices represented approximately 72% of segment sales and generated double-digit organic sales growth.

Contract-Manufactured Products Segment

In the fourth-quarter 2021, net sales declined by 3.6% to $121.5 million. Organic sales declined by 2.1%, with currency translation decreasing sales growth by 150 basis points. Segment performance was led by consumer products and medical device products.

In the full-year 2021, net sales grew by 3.2% to $514.7 million. Organic sales growth was 1.7%, with currency translation increasing sales growth by 150 basis points.

Full-Year 2021 Financial Highlights

Operating cash flow was $584.0 million, an increase of 23.6%. Capital expenditures were $253.4 million, compared with $174.4 million in 2020. Free cash flow (operating cash flow minus capital expenditures) was $330.6 million, an increase of 10.9%.

Full-Year 2022 Financial Guidance

Full-year 2022 net sales are expected to be in a range of $3.050 billion to $3.075 billion.

◦Organic sales growth is expected to be approximately 10%.

◦Net sales guidance includes an estimated full-year 2022 headwind of $70 million based on current foreign exchange rates.

Full-year 2022 reported-diluted EPS is expected to be in a range of $9.20 to $9.35.

◦Full-year reported-diluted EPS guidance range includes an estimated headwind of approximately $0.21 based on current foreign currency exchange rates.

◦This reported-diluted EPS guidance range assumes a full-year 2022 tax rate of 23%, which does not include potential tax benefits from stock-based compensation. As in prior years, we are not including potential 2022 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 2022 would provide a positive adjustment to our full-year EPS guidance.

Full-year 2022 capital spending is expected to be $380 million. This includes incremental capital spending to support capacity expansions at existing HVP facilities.

Forward-Looking Statements

Certain forward-looking statements appear in this release and include such words as “continued,” “growth,” “will continue,” “well-positioned,” “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, entitled “Risk Factors,” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

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.

18 Notes to Non-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 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.
