West Reports First-Quarter 2026 Results

–Strong Start to the Year and Raising Full Year Revenue and EPS guidance

Exton, PA, April 23, 2026 – West Pharmaceutical Services, Inc. (NYSE: WST), a leading provider of innovative, high-quality injectable solutions and services, today announced its financial results for the first quarter of 2026.

First-Quarter Summary (comparisons to prior-year period)

•Net sales of $844.9 million increased 21.0%; organic growth was 15.3%.

•Diluted earnings per share ("EPS") of $1.92 increased 56.1%.

•Adjusted-diluted EPS of $2.13 increased 46.9%.

•Operating cash flow was $89.9 million. Capital expenditures were $42.7 million. Free cash flow (defined as operating cash flow less capital expenditures) was $47.2 million.

•The Company repurchased 1.2 million shares for $297.6 million at an average price of $243.57 per share under its share repurchase program that was announced in mid-February 2026.

Outlook for Full-Year and Second Quarter 2026

•Full-year 2026 net sales guidance increased to a range of $3.295 billion to $3.350 billion, up from $3.215 billion to $3.275 billion and full year 2026 adjusted-diluted EPS guidance increased to a range of $8.40 to $8.75, up from $7.85 to $8.20.

•Second quarter 2026 net sales are expected to be in the range of $830 million to $850 million, up 8.3% to 10.9% reported and up 7.0% to 9.6% organic.

Eric M. Green, President, Chief Executive Officer and Chair of the Board, commented: “I am pleased to report a very strong start to the year with revenues and adjusted EPS exceeding expectations. Our revenues grew 15% organically, driven by our High Value Products Components business with double-digit growth in both GLP-1 and non-GLP-1 revenues. The better-than-expected performance can be attributed to continued market demand and the team’s outstanding efforts in ramping up production, especially in Europe. As a result of these excellent first quarter results and expected continued momentum in our business, we are increasing our full-year 2026 guidance.”

Proprietary Products Segment

Net sales of $694.3 million grew by 23.3% and increased 17.5% on an organic basis.

•High-Value Product ("HVP") Components net sales of $409.3 million increased 29.6% and rose 22.6% on an organic basis driven by strength in Westar® and NovaPure® products. HVP Components accounted for 48% of total company net sales in the quarter.

•HVP Delivery Devices net sales of $123.6 million increased by 29.0%, and were up 27.5% on an organic basis, driven by increased sales of self-injection device platforms and Daikyo Crystal Zenith®. HVP Delivery Devices accounted for 15% of total company net sales in the quarter.

•Standard Products net sales of $161.4 million increased by 6.7% and rose 0.5% on an organic basis. Standard Products accounted for 19% of total company net sales this quarter.

West Vantage Segment

Effective in the first quarter of 2026, the Company renamed its "Contract-Manufactured Products" reportable segment to "West Vantage™" to better align with its current strategic focus and offerings. This change in name does not affect the composition of the reportable segment, nor does it impact previously reported segment financial information. Net sales of $150.6 million increased by 11.6% and rose 6.2% on an organic basis. Segment performance was driven by an increase in sales of self-injection devices for obesity and diabetes. West Vantage accounted for 18% of total company net sales in the quarter.

Full-Year 2026 Financial Guidance

•The Company is increasing its full-year 2026 net sales guidance range to $3.295 billion to $3.350 billion, which continues to assume a mid-year close for the sale of SmartDose® 3.5mL to Abbvie, up from $3.215 billion to $3.275 billion.

◦Reported net sales growth is now anticipated to be in the range of 7.2% to 9.0%, and organic net sales growth is expected to be in the range of 7% to 9%.

◦Net sales guidance includes an estimated full-year 2026 benefit of approximately 2 percentage points based on current foreign currency exchange rates.

◦SmartDose® 3.5mL generated $55 million in revenues in the second half of 2025. These revenues are excluded to calculate our full-year 2026 organic revenue growth guidance.

•The Company is increasing its full-year 2026 adjusted-diluted EPS guidance range to $8.40 to $8.75, up from the previous range of $7.85 to $8.20.

•Capital spending guidance is unchanged from a range of $250 million to $275 million.

Second-Quarter 2026 Financial Guidance

•The Company is introducing its second-quarter 2026 net sales guidance range of $830 million to $850 million.

◦Reported net sales growth anticipated to be in the range of 8.3% to 10.9%, organic net sales growth is expected to be in the range of 7.0% to 9.6%.

◦Net sales guidance includes an estimated second-quarter 2026 benefit of approximately 1.3 percentage points based on current foreign currency exchange rates.

These statements are based on current expectations and assumptions and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. For additional information regarding these risks as well as other risks, uncertainties and factors that could affect our forward-looking statements, please refer to Part I Item 1A, entitled "Risk Factors," of the Company's most recent Annual Report on Form 10-K and any amendments thereto, as well as the Company's most recently filed Quarterly Reports on Form 10-Q and other filings the Company makes with the Securities and Exchange Commission.

Non-U.S. GAAP Financial Measures

The Company reports its financial results in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). However, management also uses certain non-U.S. GAAP financial measures in evaluating our results of operations. Management believes that this information provides users with a valuable insight into our overall performance and financial position. As a result, this release contains certain non-GAAP financial measures, including organic net sales, adjusted-diluted EPS and adjusted operating profit. 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 currency exchange rates in effect during the comparable prior-year period. We may also refer to financial results, such as adjusted-diluted EPS and adjusted operating profit, that 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. These non-U.S. GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s results prepared in accordance with U.S. GAAP. A reconciliation of these non-U.S. GAAP measures to the comparable U.S. GAAP financial measures is included in the accompanying tables.

3 This presentation and any accompanying management commentary contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements regarding the Company's expectations regarding future events, financial guidance and financial or operational performance. Forward- looking statements may be identified by words such as "believe," "expect," "intend," "estimate," "plan," "anticipate," "project," "forecast," "guidance," "target," "may," "will," "continue" and similar expressions. These statements are based on current expectations and assumptions and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such forward-looking statements. For additional information regarding these risks as well as other risks, uncertainties and factors that could affect our forward- looking statements, please refer to Part I Item 1A, entitled "Risk Factors," of the Company's most recent Annual Report on Form 10-K and any amendments thereto, as well as the Company's most recently filed Quarterly Reports on Form 10-Q and other filings the Company makes with the Securities and Exchange Commission. Forward-looking statements speak only as of the date of this press release. Except as required by law or regulation, West Pharmaceutical Services, Inc. undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. The Company reports its financial results in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). However, management also uses certain non-U.S. GAAP financial measures in evaluating our results of operations. Management believes that this information provides users with a valuable insight into our overall performance and financial position. As a result, this presentation and any accompanying management commentary contain certain non- GAAP financial measures, including organic net sales, adjusted- diluted earnings per share and adjusted operating profit. 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 currency exchange rates in effect during the comparable prior-year period. We may also refer to financial results, such as adjusted-diluted EPS and adjusted operating profit, that 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. These non-U.S. GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s results prepared in accordance with U.S. GAAP. Reconciliations of these non-U.S. GAAP measures to the comparable U.S. GAAP financial measures are included in the accompanying tables at the end of this presentation and in today's press release.
