Second Quarter 2024 Highlights

Net sales of $1.1 billion declined 10.7% versus the prior year quarter. Organic1 net sales decreased 9.1%, due primarily to -6.8 percentage points from lower net sales of infant formula driven by actions to augment and strengthen the infant formula network, and -4.0 percentage points due to lower net sales in the Upper Respiratory and Pain Sleep Aids categories stemming from lower seasonal demand. These factors more than offset organic net sales growth of +1.7 percentage points across the rest of the business.

Consumer Self-Care International ( CSCI ) net sales declined 2.5% compared to the prior year quarter. Organic net sales growth was +1.0%, including -3.5 percentage points from lower net sales in the Upper Respiratory and Pain Sleep Aids categories due to lower seasonal demand and supply constraints. This impact was offset by +4.5 percentage points from strength across the rest of the business.

Consumer Self-Care Americas ( CSCA ) net sales decreased 15.5% compared to the prior year quarter, stemming primarily from -10.8 percentage points from lower net sales of infant formula driven by actions to augment and strengthen the infant formula network, and -4.4 percentage points from lower net sales in the Upper Respiratory and Pain Sleep Aids categories due to lower seasonal demand and SKU prioritization actions to enhance margins.

GAAP ( reported ) gross margin was 37.0%, a 120 basis points increase compared to the prior year quarter. Non-GAAP ( adjusted ) gross margin expanded 190 basis points to 40.6%.

GAAP operating loss was $(27) million, compared to income of $57 million in the prior year quarter. Adjusted operating income of $139 million, increased 1.5% compared to the prior year period. Excluding the year-over-year impact from infant formula, adjusted operating income grew 16.7%.

Reported operating margin was (2.5)%, a 730 basis points decrease compared to the prior year quarter. Adjusted operating margin expanded 160 basis points to 13.1%, driven primarily by benefits from Project Energize.

Reported diluted earnings (loss) per share was $(0.77), compared to reported diluted earnings per share ( EPS ) of $0.06 in the prior year quarter.

Adjusted diluted EPS was $0.53, compared to $0.63 in the prior year quarter, a decline of $0.10 per share due primarily to discrete tax benefits in the prior year quarter of $0.09 and a year-over-year impact of -$0.14 per share from infant formula, which was mostly offset by the rest of the business.

Cash and cash equivalents2 on the balance sheet as of June 29, 2024 were $543 million, not including upfront proceeds of $205 million received from the divested HRA Pharma Rare Diseases business completed on July 10, 2024.

First Half 2024 Highlights

Net sales of $2.1 billion decreased 9.6% versus the prior year period. Organic net sales decreased 8.1%, due primarily to -5.3 percentage points from lower net sales of infant formula driven by actions to augment and strengthen the infant formula network, -3.3 percentage points from lower net sales in the Upper Respiratory and Pain Sleep Aids categories (excluding SKU prioritization actions) due to lower seasonal demand and -2.4 percentage points from SKU prioritization actions to enhance margins. These factors more than offset organic net sales growth of +2.9 percentage points across the rest of the business.

CSCI first half net sales of $869 million grew 1.0% compared to the prior year period. Organic net sales grew 3.9%, including -3.6 percentage points from lower net sales in the Upper Respiratory and Pain Sleep Aids categories due to lower seasonal demand and supply constraints.

CSCA first half net sales of $1.3 billion decreased 15.6% compared to the prior year period, stemming from -8.6 percentage points from lower net sales of infant formula, and -6.8 percentage points from SKU prioritization actions and lower net sales in the Upper Respiratory and Pain Sleep Aids categories.

Adjusted diluted EPS for the first half of 2024 was $0.83, as compared to $1.08 in the prior year period, due primarily to a year-over-year impact from infant formula of -$0.43 per share and discrete tax benefits in the prior year period of $0.08 per share.

Fiscal Year 2024 Outlook

Company updates its fiscal 2024 organic net sales growth outlook versus the prior year to -3% to -1%, from +1% to +3%, and total net sales growth outlook to -5% to -3% from flat, due primarily to lower seasonal demand experienced in the first half of 2024 and expected lower distribution in U.S. store brand in the second half of 2024.

The Company reaffirms its fiscal 2024 adjusted diluted EPS outlook of $2.50-$2.65, as increased profitability from faster than anticipated recovery in the infant formula business, improved product mix and lower selling expenses are expected to be offset by flow-through from the updated net sales outlook.

Dublin, Ireland - August 2, 2024 - Perrigo Company plc (NYSE PRGO) ("Perrigo" or the "Company"), a leading provider of Consumer Self-Care Products, today announced financial results from continuing operations for the second quarter ended June 29, 2024. All comparisons are against the prior year fiscal second quarter, unless otherwise noted.

President and CEO, Patrick Lockwood-Taylor commented, During the second quarter, we continued to progress our blueprint to build One Perrigo by driving our Project Energize and Supply Chain Reinvention efficiency programs and further consumerizing, simplifying and scaling our business. As we are building out critical capabilities needed to win in self-care, we have also faced challenges, notably in the infant formula regulatory environment in the U.S. as we work together to ensure the supply of this critical product for caregivers and babies. I have been especially proud to work alongside my team as we have addressed these issues head on and with a spirit of resiliency. We are emerging as a stronger company as a result.

Lockwood-Taylor continued, Our second quarter topline results were impacted by actions to augment and strengthen infant formula, lower seasonal demand compared to the prior year and, to a lesser extent, final SKU prioritization actions to enhance margins in CSCA. These factors more than offset growth across the rest of our portfolio. We continued to execute well throughout our business, which delivered meaningful margin expansion. And, we achieved first half 2024 adjusted diluted EPS in line with our 2024 outlook.

Lockwood-Taylor concluded, We are currently making significant progress in quality control, production, packaging and release attainment. We are increasingly confident in the second half profit recovery of this business, which in addition to improved mix and lower variable expenses, are expected to offset lower seasonal demand in the first half of the year and lower distribution in U.S. store brand in the second half of the year. This leads us to reaffirm our 2024 adjusted EPS outlook.

Refer to Tables I through VII at the end of this press release for a reconciliation of non-GAAP adjustments to the current year and prior year periods and additional non-GAAP information. The Company's reported results are included in the attached Consolidated Statements of Operations, Balance Sheets and Statements of Cash Flows.

Perrigo has successfully transformed into a pure-play consumer self-care company and is embarking on the next stage of its self-care journey - evolving to One Perrigo. This evolution will create sustainable, value accretive growth through a blended-branded business model that better positions the Company to win in self-care.

As part of the Company's sustainable, value accretive growth strategy, the Company launched Project Energize - a global investment and efficiency program to drive the next evolution of capabilities and organizational agility during the first quarter of 2024. This three-year program is

expected to produce significant benefits in the Company's long-term business performance by enabling our One Perrigo growth strategy, increasing organizational agility and mitigating impacts from augmenting and strengthening infant formula.

Project Energize is expected to deliver annualized pre-tax savings in the range of $140 million to $170 million by 2026. The Company expects $40 million to $60 million of these savings to be reinvested to drive its blended-branded business model. Restructuring and related charges associated with these actions are estimated to be in the range of $140 million to $160 million, including $20 million to $40 million in investments to enhance capabilities, and are expected to be substantially incurred by the end of 2026. Restructuring activities as part of Project Energize are expected to result in the net reduction of approximately 6% of total Perrigo roles. Year-to-date, Project Energize has achieved gross savings of approximately $53 million.

Perrigo Second Quarter 2024 Results from Continuing Operations

Reported net sales of $1.1 billion decreased $128 million, or 10.7%, due primarily to a decline in organic net sales of 9.1%, exited product lines of -0.6% and foreign currency translation of -0.9%. Organic net sales comprised strategic pricing actions of +3.7 percentage points and volume mix of -12.8 percentage points, due primarily to actions to augment and strengthen the infant formula network.

Organic net sales were impacted by -6.8 percentage points due to lower net sales of infant formula and -4.0 percentage points due to lower net sales in the Upper Respiratory and Pain Sleep Aids categories. These factors more than offset organic net sales growth of +1.7 percentage points across the rest of the business, led by 1) growth in branded product offerings, including Compeed , Mederma and EllaOne , 2) e-commerce growth, and 3) new products, including the launch of Opill in the U.S.

Reported gross profit of $395 million, decreased $33 million, or 7.8%. Adjusted gross profit of $433 million decreased $29 million, or 6.4%, due primarily to actions to augment and strengthen infant formula, lower net sales volumes and overhead absorption, and higher cost of goods sold inflation in the CSCI segment. These factors were partially offset by savings from the Company's Supply Chain Reinvention and Project Energize programs.

Reported gross margin was 37.0%, a 120 basis points increase versus the prior year quarter. Adjusted gross margin expanded 190 basis points to 40.6%, driven by the same factors as adjusted gross profit, in addition to benefits from purposeful SKU prioritization actions in CSCA.

Reported operating loss of $27 million compared to operating income of $57 million in the prior year period, due primarily to restructuring charges related to Project Energize, an impairment recognized as part of the sale of HRA Pharma Rare Diseases business and unusual litigation costs. Adjusted operating income increased $2 million to $139 million as Project Energize cost savings and lower variable expenses were partially offset by the decrease in gross profit. Excluding infant formula from both years, adjusted operating income grew 16.7%.

Reported operating margin was (2.5)%, a 730 basis points decrease versus the prior year quarter, due primarily to the same factors as reported operating loss. Adjusted operating margin was 13.1%, an increase of 160 basis points versus the prior year quarter, due primarily to adjusted gross margin flow through and Project Energize cost savings.

Reported net loss was $106 million, or ($0.77) per diluted share, compared to reported net income of $9 million, or $0.06 per diluted share, in the prior year. Second quarter 2024 adjusted net income was $74 million, or $0.53 per diluted share, compared to $87 million, or $0.63 per diluted share, in the prior year. The decline in adjusted EPS of $0.10 was due primarily to discrete tax benefits in the prior year quarter of $0.09 and a -$0.14 year-over-year impact from Infant formula, which was partially offset by the rest of the business.

Second Quarter 2024 Business Segment Results from Continuing Operations

Consumer Self-Care Americas Segment (CSCA)

CSCA reported net sales of $634 million decreased $117 million, or 15.5%, due primarily to a decline in organic net sales of 15.1% and exited product lines of -0.4%.

Organic net sales were impacted by 1) -10.8 percentage points impact from lower net sales of infant formula, and 2) -4.4 percentage points from lower net sales in the Upper Respiratory and Pain Sleep Aids categories due to lower seasonal demand and SKU prioritization actions to enhance margins. Growth in e-commerce, new products, including Opill , and products in the Lifestyle category were offset by the remaining business.

Reported gross profit of $190 million decreased $35 million, or 15.5%. Adjusted gross profit declined $28 million to $201 million due primarily to lower sales volumes primarily in Nutrition and unfavorable overhead absorption stemming from OTC manufacturing, partially offset by strategic pricing actions, and Supply Chain Reinvention and Project Energize cost savings.

Reported gross margin was 29.9%, flat versus the prior year quarter. Adjusted gross margin expanded 120 basis points to 31.7%, driven by the same factors as adjusted gross profit, primarily Supply Chain Reinvention and Project Energize cost savings.

Reported operating income was $69 million compared to $98 million in the prior year quarter. Adjusted operating income declined $23 million, or 19.9%, to $91 million as adjusted gross profit flow through and higher branded advertising and promotion investments were partially offset by Project Energize cost savings.

Reported operating margin was 10.9%, a 210 basis points decrease versus the prior year quarter. Adjusted operating margin declined 80 basis points to 14.4% driven by the same factors as adjusted operating income.

Consumer Self-Care International Segment (CSCI)

CSCI reported net sales growth declined 2.5%, as organic net sales growth of 1.0%, was more than offset by -1.1% from product line exits and -2.4% from foreign currency translation.

Organic net sales were driven by growth in the Skin Care and Women's Health categories stemming from market share gains in key brands, strategic pricing actions and new products. These drivers were offset by lower net sales in the Upper Respiratory and Pain Sleep Aids categories, due to lower seasonal demand and supply constraints.

Reported gross profit of $205 million increased $1 million, or 0.7%. Adjusted gross profit of $231 million declined 0.7%, or an increase of 1.8% on a constant currency basis, as strategic pricing actions, new products and Supply Chain Reinvention savings were partially offset by lower sales volumes and cost of goods sold inflation.

Reported gross margin was 47.5%, an increase of 150 basis points compared to the prior year quarter. Adjusted gross margin expanded 100 basis points to 53.6% driven by the same factors as adjusted gross profit.

Reported operating loss was $10 million compared to operating income of $9 million in the prior year quarter. Adjusted operating income increased 29.5%, or 34.4% on a constant currency basis, to $91 million, due primarily to lower advertising and promotion investments and Project Energize cost savings.

Reported operating margin was (2.4)%, a 440 basis points decrease versus the prior year quarter, due primarily to an impairment recognized as part of the sale of HRA Pharma Rare Diseases business and increased restructuring expenses. Adjusted operating margin expanded 520 basis

points to 21.0%, due primarily to operating leverage and lower advertising and promotion investments.

Cash Flow and Balance Sheet

Second quarter 2024 cash from operations was $10 million compared to cash flow of $53 million last year. Capital expenditures were $29 million compared to $20 million in the prior year. The Company returned $38 million to shareholders through dividends during the quarter. Cash and cash equivalents2 on the balance sheet as of June 29, 2024 were $543 million, not including proceeds of $205 million received from the divestment of the HRA Pharma Rare Diseases business completed on July 10, 2024. Total debt as of June 29, 2024 was $4.1 billion, flat compared to the prior year.

The Company is updating its fiscal 2024 organic net sales growth outlook versus the prior year to approximately -3% to -1%, from +1% to +3%, and total net sales growth outlook to -5% to -3% from flat, due primarily to lower seasonal demand experienced in the first half of 2024 and expected lower distribution in U.S. store brand in the second half of 2024.

The Company is reaffirming

Interest expense of approximately $180 million,

Full year adjusted tax rate of approximately 20.5%,

Adjusted diluted EPS of between $2.50 to $2.65, and

Operating cash flow conversion (operating cash flow as a percentage of adjusted net income) of approximately 90% to 100%.

The Company cannot reconcile its expected organic net sales growth, adjusted diluted earnings per share to diluted earnings per share, adjusted tax rate or operating cash flow conversion under Fiscal 2024 Outlook without unreasonable effort because certain items that impact net income and other reconciling metrics are out of the Company's control and or cannot be reasonably predicted at this time. These items include, but are not limited to uncertainty of non-recurring infant formula related charges and timing and amount of restructuring charges and the income tax effects of these items or other income tax-related events.

Adverse results with respect to pending litigation could have a material adverse impact on the Company's operating results, cash flows and liquidity, and could ultimately require the use of corporate assets to pay damages, reducing assets that would otherwise be available for other corporate purposes. These and other important factors, including those discussed under "Risk Factors" in the Company's Form 10-K for the year ended December 31, 2023, as well as the Company's subsequent filings with the United States Securities and Exchange Commission, may cause actual results, performance or achievements to differ materially from those expressed or

implied by these forward-looking statements. The forward-looking statements in this press release are made only as of the date hereof, and unless otherwise required by applicable securities laws, the Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

This press release contains certain non-GAAP measures. A non-GAAP financial measure is defined as a numerical measure of a company's financial performance that excludes or includes amounts different from the most directly comparable measure calculated and presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP) in the statements of operations, balance sheets or statements of cash flows of the Company. Pursuant to the requirements of the U.S. Securities and Exchange Commission, the Company has provided reconciliations to the most directly comparable U.S. GAAP measures for the following non-GAAP financial measures referred to in this press release

net sales growth on an organic basis, which excludes acquisitions, divested businesses, exited product lines, and the impact of currency,

adjusted gross profit,

adjusted net income,

adjusted operating income,

adjusted diluted earnings per share,

constant currency net sales growth, adjusted operating income, and adjusted gross profit,

adjusted operating margin, and

adjusted gross margin.

These non-GAAP financial measures should be considered as supplements to the GAAP reported measures, should not be considered replacements for, or superior to the GAAP measures and may not be comparable to similarly named measures used by other companies. The Company presents these non-GAAP financial measures in order to provide transparency to our investors because they are measures that management uses to assess both management performance and the financial performance of our operations and to allocate resources. In addition, management believes that these measures may assist investors with understanding and evaluating our initiatives to drive improved financial performance and enables investors to supplementally compare our operating performance with the operating performance of our competitors including with those of our competitors having different capital structures. While we have excluded certain of these items from historical non-GAAP financial measures, there is no guarantee that the items excluded from non-GAAP financial measures will not continue into future periods. For instance, we expect to continue to experience and report restructuring-related charges associated with continued execution of our strategic initiatives.

The Company provides non-GAAP financial measures as additional information that it believes is useful to investors and analysts in evaluating the performance of the Company's ongoing operating trends, facilitating comparability between periods and, where applicable, with companies in similar industries and assessing the Company's prospects for future performance. These non-GAAP financial measures exclude items, such as impairment charges, restructuring charges, and acquisition and integration-related charges, that by their nature affect comparability of operational performance or that we believe obscure underlying business operational trends. The intangible asset amortization excluded from these non-GAAP financial measure represents the entire amount recorded within the Company's GAAP financial statements and is excluded because the

amortization, unlike the related revenue, is not affected by operations of any particular period unless an intangible asset becomes impaired or the estimated useful life of an intangible asset is revised. The revenue generated by the associated intangible assets has not been excluded from the related non-GAAP financial measure. The non-GAAP measures the Company provides are consistent with how management analyzes and assesses the operating performance of the Company, and disclosing them provides investor insight into management's view of the business. Management uses these adjusted financial measures for planning and forecasting in future periods, and evaluating segment and overall operating performance. In addition, management uses certain of the profit measures as factors in determining compensation.

Non-GAAP measures related to profit measurements, which include adjusted gross profit, adjusted net income, adjusted operating income, adjusted diluted EPS, adjusted gross margin and adjusted operating margin are useful to investors as they provide them with supplemental information to enhance their understanding of the Company's underlying business performance and trends, and enhance the ability of investors and analysts to compare the Company's period-to-period financial results. Management believes that adjusted gross margin and adjusted operating margin are useful to investors, in addition to the reasons discussed above, by allowing them to more easily compare and analyze trends in the Company's peer business group and assisting them in comparing the Company's overall performance to that of its competitors. The Company also discloses net sales growth excluding the impact of currency on an organic basis. The Company believes these supplemental financial measures provide investors with consistency in financial reporting, enabling meaningful comparisons of past and present underlying operating results, and also facilitate analysis of the Company's operating performance and acquisition and divestiture trends.
