These statements relate to future events or our future financial performance and involve known and unknown risks, uncertainties and other factors that may cause our, or our industry’s actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by any forward-looking statements. In particular, statements about our expectations, beliefs, plans, objectives, assumptions, future events or future performance contained in this report, including certain statements contained in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” are forward-looking statements. In some cases, forward- looking statements can be identified by terminology such as “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” "forecast," “predict,” “potential” or the negative of those terms or other comparable terminology. We have based these forward-looking statements on our current expectations, assumptions, estimates and projections. While we believe these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond our control, including: the timing, amount and cost of any share repurchases; future impairment charges; the success of management transition; customer acceptance of new products; competition from other industry participants, some of whom have greater marketing resources or larger market shares in certain product categories than we do; pricing pressures from customers and consumers; potential third-party claims and litigation, including litigation relating to our restatement of previously-filed financial information; potential impacts of ongoing or future government investigations and regulatory initiatives; resolution of uncertain tax positions; the impact of U.S. tax reform legislation and healthcare policy; general economic conditions; fluctuations in currency exchange rates and interest rates; the consummation of announced acquisitions or dispositions and the success of such transactions, and our ability to realize the desired benefits thereof; and our ability to execute and achieve the desired benefits of announced cost-reduction efforts and other initiatives. In addition, we may be unable to remediate one or more previously identified material weaknesses in our internal control over financial reporting.

NOTE REGARDING FISCAL YEAR Our fiscal year previously consisted of a 52- or 53-week year ending on or around June 30 of each year with each quarter ending on the Saturday closest to each calendar quarter end. Beginning on January 1, 2016, we changed our fiscal year to begin on January 1 and end on December 31 of each year. As a result of our change in year end, this report on Form 10-K discloses the results of our operations for the twelve-month periods from January 1, 2017 through December 31, 2017 and January 1, 2016 through December 31, 2016. The six months ended December 31, 2015 reflects our financial results from June 28, 2015 through December 31, 2015. The year ended June 27, 2015 reflects our financial results for the twelve-month period from June 29, 2014 to June 27, 2015. 1 We cut off our quarterly accounting periods on the Saturday closest to the end of the calendar quarter, with the fourth quarter ending on December 31 of each year. 2 Perrigo Company plc - Item 1 Business Overview ITEM 1. BUSINESS PART I. Perrigo Company plc was incorporated under the laws of Ireland on June 28, 2013. We became the successor registrant to Perrigo Company, a Michigan corporation, on December 18, 2013 in connection with the acquisition of Elan Corporation, plc ("Elan"). Unless the context requires otherwise, the terms "Perrigo", the "Company", "we," "our," "us," and similar pronouns used herein refer to Perrigo Company plc, its subsidiaries, and all predecessors of Perrigo Company plc and its subsidiaries. WHO WE ARE We are a leading global healthcare company, delivering value to our customers and consumers by providing Quality Affordable Healthcare Products®. Founded in 1887 as a packager of home remedies, we have built a unique business model that is best described as the convergence of a fast-moving consumer goods company, a high-quality pharmaceutical manufacturing organization and a world-class supply chain network. We believe we are one of the world's largest manufacturers of over-the-counter (“OTC”) healthcare products and suppliers of infant formulas for the store brand market. We are a leading provider of branded OTC products throughout Europe, and also a leading producer of generic pharmaceutical topical products such as creams, lotions, and gels, as well as nasal sprays and injection ("extended topical") prescription drugs. We are headquartered in Ireland, and sell our products primarily in North America and Europe, as well as in other markets, including Australia, Israel and China. MAJOR DEVELOPMENTS IN OUR BUSINESS Restructuring On February 21, 2017, we approved a workforce reduction plan as part of a larger cost optimization strategy across the Company, which was completed during the year. Our plan was to reduce our global workforce by approximately 750 employees, which included some actions already taken and 235 employees who had elected to participate in a voluntary early retirement program. This represented a reduction of approximately 14% of our global non-production workforce. The changes to our workforce varied by country, based on legal requirements and required consultations with works councils and other employee representatives, as appropriate. During the year ended December 31, 2017, we recognized $61.0 million of restructuring expenses (refer to Item 8. Note 18). In addition, during the year ended December 31, 2017, we executed a supply chain reorganization which continues to generate savings for both our North American and International segments. 3 Perrigo Company plc - Item 1 Business Overview Segments Our reporting segments are as follows: • Consumer Healthcare Americas ("CHCA"), comprises our U.S., Mexico and Canada consumer healthcare business (OTC, contract, infant formula and animal health categories). • Consumer Healthcare International ("CHCI"), comprises our branded consumer healthcare business primarily in Europe and our consumer focused businesses in the U.K., Australia, and Israel. This segment also includes our U.K. liquid licensed products business. • Prescription Pharmaceuticals ("RX"), comprises our U.S. Prescription Pharmaceuticals business. We also had two legacy operating segments, Specialty Sciences and Other, which contained our Tysabri® financial asset and Active Pharmaceuticals business ("API") businesses, respectively, which we divested (refer to Item 8. Note 2 and Note 6). Following these divestitures, there were no substantial assets or operations left in either of these segments. Effective January 1, 2017, all expenses associated with our former Specialty Sciences segment were moved to unallocated expenses. Financial information related to our business segments and geographic locations can be found in Item 8. Note 19. Our segments reflect the way in which our management makes operating decisions, allocates resources and manages the growth and profitability of the Company. Omega Acquisition On March 30, 2015, we acquired Omega Pharma Invest N.V. ("Omega"), one of the largest OTC companies in Europe, for $3.0 billion in equity and cash and assumed debt of $1.6 billion, for a total purchase price of $4.6 billion. The Omega acquisition expanded our OTC leadership position into continental Europe, accelerated our international expansion and geographic diversification through enhanced scale and a broader footprint, and diversified our net sales and cash flow streams. The broader European platform established through the Omega acquisition, facilitated the acquisition of a portfolio of well-established OTC brands sold primarily in Europe from GlaxoSmithKline Consumer Healthcare (“GSK”), on August 28, 2015 and Naturwohl Pharma, GmbH ("Naturwohl"), with its leading German dietary supplement brand, Yokebe®, on September 15, 2015 (refer to Item 8. Note 2). Subsequently, during the year ended December 31, 2016, we identified impairment indicators associated with certain intangible assets and goodwill, which required us to test these assets for impairment. As a result, we recorded total impairments of $2.0 billion (refer to Item 8. Note 3). Elan Acquisition On December 18, 2013, we acquired Elan in a cash and stock transaction totaling $9.5 billion. The acquisition led to the creation of our then new corporate structure headquartered in Dublin, Ireland. We have utilized this structure to continue to grow in our core markets and further expand outside of the U.S. The acquisition also provided us with the Tysabri® financial asset. In November 2016, we initiated a strategic review of the Tysabri® financial asset. During this review, we identified impairment indicators of the fair value of that royalty stream, which led to a goodwill impairment recorded during the year ended December 31, 2016 (refer to Item 8. Note 3 and Note 6 for additional information on the impairment and fair value adjustments, respectively). On March 27, 2017, we announced the completed divestment of the Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in royalties earned if global net sales of Tysabri® meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017 (refer to Item 8. Note 6 for additional information on the Royalty Pharma contingent milestone payments). Divestitures In addition to the above mentioned Tysabri® financial asset disposal, as a result of our continued efforts to implement certain initiatives, streamline our organization and review our portfolio, during the year ended December 31, 2017, we divested the following (refer to Item 8. Note 2): 4 Perrigo Company plc - Item 1 Business Overview • Certain Abbreviated New Drug Applications ("ANDAs") for $15.0 million in proceeds. • Our animal health pet treats plant fixed assets for $7.7 million in proceeds. • Our India API business for $22.2 million in proceeds. • Our Russian business for €12.7 million ($15.1 million) in proceeds. • Our Israel API business for $110.0 million in proceeds. NEW PRODUCTS We consider a product to be new if it was (i) reformulated, (ii) involved product line extension due to changes in characteristics such as strength, flavor, or color, (iii) involved a change in product status from "prescription only" ("Rx") to OTC, (iv) was a new generic or branded launch, (v) was provided in a new dosage form or (vi) was sold to a new geographic area with different regulatory authorities, in all cases, within 12 months prior to the end of the period for which net sales are being measured. During the year ended December 31, 2017, new product sales were $209.7 million. CONSUMER HEALTHCARE AMERICAS Overview The CHCA segment is focused primarily on the sale of OTC store brand products, including cough, cold, allergy and sinus, analgesic, gastrointestinal, smoking cessation, infant formula and food, animal health, and diagnostic products in the U.S., Mexico and Canada. We are a leading provider of consumer healthcare products sold to consumers via store brands and also sell consumer healthcare products under our own brands. Consumer awareness and knowledge of the quality and value that OTC store brand products represent continues to grow due to retailer efforts to promote their own label programs. During the year ended December 31, 2017, our CHCA segment represented approximately 49% of consolidated net sales. The CHCA segment develops, manufactures, and markets products that are comparable in quality and effectiveness to national brands. Store brand products must meet the same U.S. Food and Drug Administration ("FDA") requirements as national brands within the U.S. and the requirements of comparable regulatory bodies outside the U.S. In most instances our product packaging is designed to invite and reinforce comparison to national brand products, while communicating store brand value to consumers. The cost of store brand products to retailers is significantly lower than that of comparable nationally advertised brand-name products. Generally, retailers’ dollar profit per unit of store brand product is greater than the dollar profit per unit of the comparable national brand product. The retailer, therefore, can price a store brand product below the competing national brand product and realize a greater profit margin. The consumer benefits by receiving a high quality product at a price below the comparable national brand product. As a result, our business model results in consumers saving money on their healthcare spending. We are dedicated to continuing to be the leader in developing and marketing new OTC store brand products, including infant formula, and have a research and development ("R&D") staff that we believe is one of the most experienced in the industry at developing products comparable in formulation and quality to national brand products. Our R&D team also responds to changes in existing national brand products by reformulating existing products. For example, in the OTC pharmaceutical market, certain new products are the result of changes in product status from Rx to OTC. These “Rx-to-OTC switches” require FDA approval through a process initiated by the drug innovator. The drug innovator usually begins the process by filing a New Drug Application ("NDA"), which is often followed by filing an ANDA. New drugs are also marketed through the FDA's OTC monograph process, which allows for the production of drugs that are generally recognized as safe and effective without pre-marketing approval. The CHCA segment also develops, manufactures, and distributes certain branded products when the strategy is synergistic with our store brand business. Branded products include the Good Sense®, Sergeant's®, Sentry®, Zephrex D®, PetArmor®, and ScarAway® brand names. 5 Perrigo Company plc - Item 1 CHCA We manufacture a significant portion of our CHCA segment's products at our plants in the U.S., Mexico, and Israel, and we source our remaining needs from third parties. We rely on both internal R&D and strategic product development agreements with outside sources to develop new products. In addition, in order to maximize both our capacity and sales of proprietary formulas, we engage in contract manufacturing, which involves producing unique ANDAs and monograph products through partnerships with major pharmaceutical and direct-to-consumer companies. We believe the increasing age of the population will drive the need for the greater value that our store brand products provide consumers. In addition, we believe that new products and products switching from Rx to OTC (as described above) will continue to drive growth within the segment. Products Our CHCA segment offers products in the following categories: Product Category Analgesics Description Pain relievers and fever reducers Cough/cold/allergy/sinus Cough, cold, allergy, and sinus products Gastrointestinal Antacids, anti-diarrheal, and anti-heartburn products Infant nutritionals Infant formula and food products Smoking cessation Gums, lozenges, and other products designed to help users quit smoking Animal health Pet health and wellness products Other Feminine hygiene, diabetes care, dermatological care, diagnostic products, scar management, and other miscellaneous healthcare products The chart below reflects net sales by product category in the CHCA segment for the year ended December 31, 2017. 6 Perrigo Company plc - Item 1 CHCA We launched a number of new CHCA products in the year ended December 31, 2017, most notably esomeprazole magnesium (store brand equivalent to Nexium® 24HR capsules), and smoking cessation products. During the year ended December 31, 2017, new product sales in the CHCA segment were $68.7 million. We, on our own or in conjunction with partners, received final FDA approval from U.S. health authorities for two new products within the CHCA segment in the year ended December 31, 2017, and as of December 31, 2017, we had eight new product applications pending FDA approval. Sales and Marketing Our customers include major global, national, and regional retail drug, supermarket, and mass merchandise chains such as Walmart, CVS, Walgreens Boots Alliance, Rite Aid, Kroger, Target, Dollar General, Sam’s Club, Costco, Petco, Petsmart, Aldi, Amazon, and major wholesalers, including McKesson, Cardinal Health, and Amerisource Bergen. We seek to establish customer loyalty through superior customer service by providing a comprehensive assortment of high quality, value-priced products; timely processing, shipment and delivery of orders; assistance in managing customer inventories; and support in managing and building the customer’s store brand business. The CHCA segment employs its own sales force to service larger customers, and uses industry brokers for other retailers. Field sales employees, with support from marketing and customer service, are assigned to specific customers in order to work most effectively with the customer. They assist customers by developing customized brand and in-store marketing programs for customers' store brand products. The primary objective of this store brand management approach is to enable our customers, retailers and wholesalers, to increase sales of their own store brand products by communicating store brand quality and value to the consumer and by inviting comparison to national brand products. Our sales and marketing personnel assist customers in the development and introduction of new store brand products and in the promotion of customers’ existing store brand products by providing market information; establishing individualized promotions and marketing programs, which may include floor displays, bonus sizes, coupons, rebates, store signs, and promotional packs; and performing consumer research. In contrast with national brand manufacturers, which incur considerable advertising and marketing expenditures targeted directly to the end user or consumer, the CHCA segment’s primary marketing efforts are channeled through retailers and wholesalers and reach the consumer through our customers’ in-store marketing programs and our digital media programs. Because the retail profit margin for store brand products is generally higher than for national brand products, retailers and wholesalers often commit funds for additional promotions. Our animal health category, which has a greater emphasis on value-branded products, promotes product awareness through direct-to-consumer advertising, including television commercials, online advertising, in-store display vehicles, and social media. In addition to in-store marketing programs, our infant formula category markets directly to consumers and healthcare professionals. Competition The markets for OTC pharmaceuticals and infant formula are highly competitive and differ for each product line and geographic region. Our primary competitors include manufacturers, such as LNK International, Inc., PL Developments, and Dr. Reddy's Labs, and brand-name pharmaceutical and consumer product companies, such as Johnson & Johnson, Pfizer, Bayer AG, GSK, Nestle S.A. (Gerber), Abbott Nutrition, and Mead Johnson Nutrition Co. The competition is highly fragmented in terms of geographic market coverage and product categories, such that a competitor generally does not compete across all product lines. However, some competitors do have larger sales volumes in certain of our categories. Additionally, national brand companies tend to have more resources committed to marketing their products and could in the future manufacture store brands of their products at lower prices than their national brand products. Competition is based on a variety of factors, including price, quality, assortment of products, customer service, marketing support, and approvals for new products (refer to Item 1A. Risk Factors - Risks Related to Operations for additional information and risks associated with competition). 7 Perrigo Company plc - Item 1 CHCA CONSUMER HEALTHCARE INTERNATIONAL Overview The CHCI segment is comprised of our branded OTC sales primarily in Europe and our consumer focused businesses in the U.K., Australia, and Israel. The CHCI segment develops, manufactures, markets and distributes many well-known European OTC brands in the cough, cold and allergy, lifestyle, personal care and derma- therapeutics, natural health and vitamins, and anti-parasite categories. In addition, the segment leverages its broad regulatory, sales, and distribution infrastructure to in-license and sell third-party brands and generic pharmaceutical products. The CHCI segment distributes these products through an extensive network of customers including pharmacies, wholesalers, drug and grocery store retailers, and para-pharmacies in 28 countries, primarily in Europe. Many CHCI products have market leading positions in the markets in which they compete. During the year ended December 31, 2017, the CHCI segment represented approximately 30% of consolidated net sales. Through continued investment in R&D partnerships and new technologies, the CHCI segment strives to offer high quality products that meet consumers' needs. The combination of internal R&D, in-sourcing, acquisitions, and partnerships support the product pipeline, both in terms of brand expansion and product improvement. In the U.K., R&D focuses on oral liquid formulations for the branded Rx products for which liquid formulations are not available, as well as the development of store brand products and products for the branded business. An additional R&D center resides in Sweden. In the rest of Europe, most R&D is performed by external partners with oversight by our teams. The segment has six plants dedicated to manufacturing certain of its products. The CHCI segment primarily focuses on building local and regional brands. In many markets outside of the U.S., a brand marketing strategy can be more effective than a store brand strategy due to the absence of mass merchandisers and large scale pharmacy chains. Additionally, the absence of a centralized regulatory environment within Europe adds to the complexity of obtaining approvals for products in these markets. While the CHCI segment sells products from over 300 brands both on its own and through third parties, it focuses its resources on its "Focus brands", which are selected on the basis of their current sales and growth potential in the OTC market. Additional resources are allocated to these brands to build strong positions in the largest, most highly profitable categories in the OTC market, while maintaining leadership in smaller branded categories. Recent Developments • Management has developed a strategy to: (1) implement a brand prioritization to address certain market dynamics, with an objective to balance the cost of advertising and promotional investments with expected contributions from category sales, (2) restructure the sales force in certain markets to more effectively serve customers, and (3) in-source certain product manufacturing and development. The combination of these actions is expected to improve the segment's focus on higher value OTC products, reduce selling costs and improve operating margins in the segment. • As part of our previously announced strategic initiatives, management implemented improvements and evaluated the overall cost structures within our CHCI segment in the following ways: • On December 8, 2016, we announced the cancellation of the unprofitable EuroGenerics NV distribution agreement in Belgium. The year-over-year effect of the cancellation, combined with the exit of certain OTC distribution agreements, reduced our net sales by $200.3 million in 2017, with an immaterial impact to operating income. • We made progress on our previously announced restructuring plans to right-size the Omega business due to the impact of market dynamics on sales volumes. During the year ended December 31, 2017, we recognized $17.1 million of restructuring expense in the CHCI segment (refer to Item 8. Note 18). 8 Perrigo Company plc - Item 1 CHCI • Management continues to evaluate the most effective business model for each country, aligning our sales infrastructure and actively integrating sales strategies with promotional programs. • On August 25, 2017, we completed the sale of our Russian business, which was previously classified as held-for-sale, to Alvogen Pharma LLC. The total sale price was €12.7 million ($15.1 million), inclusive of an estimated working capital adjustment, which resulted in an immaterial gain in the segment (refer to Item 8. Note 2). The combination of these actions improved the segment's focus on higher value OTC products, reduced selling costs and improved operating margins in the segment. • The CHCI segment has been positively impacted by market dynamics in countries such as the Nordics, Italy, and Portugal, offset by softness in certain brand categories in France and Germany, as well as unfavorable foreign currency impacts primarily in the U.K. related to Brexit. Products Below are the categories in which the CHCI segment competes and some of the top brands in each category. Product Category Cough, Cold, and Allergy Description Products that address respiratory symptoms, including traditional medications and alternative treatments such as aromatherapy solutions. Lifestyle Personal Care and Derma- Therapeutics Weight management, pregnancy and fertility kits, pain relief, sleep management, smoking cessation, and eye care. Products for the face and body, including sun care, baby-specific, and feminine hygiene products, and solutions for various skin conditions and allergies such as eczema, psoriasis and rosacea. Natural Health and Vitamin, Minerals, and Supplements ("VMS") Vitamins, minerals, supplements, and various other natural remedies. Anti-Parasite Products focused on the elimination of parasites in both humans and pets including lice treatment and insect repellent. Focus Brands Bittner®/Aflubin® Bronchenolo®/Bronchostop® Coldrex® Libenar® Physiomer® Phytosun®/Valda® Solpadeine®/Antigrippine® Niquitin® Silence®/Nytol® XLS (Medical)® Ymea® ACO® Biodermal® Canoderm® Dermalex® Lactacyd® Wartner® Abtei® Biover® Davitamon® Granufink® Jungle Formula® Paranix® The chart below reflects net sales by product category in the CHCI segment for the year ended December 31, 2017. 9 Perrigo Company plc - Item 1 CHCI We launched a number of new CHCI products in the year ended December 31, 2017, most notably a cold & flu triple active hot drink, various intimate hygiene products, derma-therapeutics, and VMS line extensions. During the year ended December 31, 2017, new product sales in the CHCI segment were $64.1 million. The CHCI segment has more than 100 strategic new products in five product categories in development, with each of its Focus brands having a five-year innovation master plan. Sales and Marketing Our customers include pharmacies, drug, and grocery stores located primarily in Europe, including Walgreens Boots Alliance, ASDA, Tesco, DM, Rossmann, ETOS, and Kruidvat. The CHCI segment sells its products primarily through an established pharmacy sales force to an extensive network of pharmacists. Our sales representatives visit pharmacists daily, ensuring strong in-store visibility of our brands and facilitating pharmacist education programs. Our sales, marketing, and regulatory teams use training/merchandising teams to work in conjunction with local sales representatives to improve our brands' presence and recognition. We seek to attract key talent from leading OTC, Fast Moving Consumer Goods ("FMCG"), and retailer companies to build strong local teams throughout the countries in which the CHCI segment operates. While CHCI products have a higher average gross margin than products sold by the CHCA segment, selling expenses are significantly higher due to the sales force mentioned above, as well as targeted advertising and promotional spending to enhance brand equity. Key marketing communication tools for the CHCI segment include TV commercials, consumer leaflets, product websites, digital and targeted promotional campaigns. Competition The competitive landscape of the European OTC market is highly fragmented, as local companies often hold leadership positions in individual product segments in particular countries. As a result, the relevant competition in each of the CHCI segment's markets is both local and global. Competitors include Sarnofi, Bayer, Reckitt Benckiser, GSK, Novartis, and Johnson & Johnson, as well as additional regional competitors. We believe our key advantage lies in our unique combination of best practices in sales, marketing, and product development from 10 FMCG and OTC/Rx, while embracing the pharmacy channel to drive self-care (refer to Item 1A. Risk Factors - Risks Related to Operations for additional information and risks associated with competition). Perrigo Company plc - Item 1 CHCI PRESCRIPTION PHARMACEUTICALS Overview The RX segment develops, manufactures, and markets a portfolio of generic prescription drugs primarily in the U.S. We define this portfolio as predominantly "extended" topical as it encompasses a broad array of topical dosage forms such as creams, ointments, lotions, gels, shampoos, foams, suppositories, sprays, liquids, suspensions, solutions, and powders. The portfolio also includes select controlled substances, injectables, hormones, oral solid dosage forms, and oral liquid formulations. During the year ended December 31, 2017, the RX segment represented approximately 20% of consolidated net sales. Our current development areas include other delivery systems such as oral liquids, metered dose inhalers, injectables, and transdermal products, some of which we are developing with third parties. Our other areas of expertise include our production capabilities for controlled substances and hormonal products. R&D efforts focus on complex formulations, many of which require costly clinical endpoint trials. We manufacture our topical and oral products in the U.S. and Israel, and also source from various FDA- approved third parties. Rx products are manufactured, labeled, and packaged in facilities that comply with strict regulatory standards and meet customers’ stringent requirements. In addition, the RX segment offers OTC products through the prescription channel (referred to as "ORx®", these products are marketed using the Perrigo name). ORx® products are OTC products that are available for pharmacy fulfillment and healthcare reimbursement when prescribed by a physician. We offer numerous ORx® products that are reimbursable through many health plans and the U.S. Medicaid and Medicare programs. We actively collaborate with other pharmaceutical companies to develop, manufacture, and market certain products or groups of products. These types of agreements are common in the pharmaceutical industry. We may choose to enter into these types of agreements to, among other things, leverage our or our collaborators' scientific R&D expertise, or utilize our extensive marketing and distribution resources (refer to Item 8. Note 1 for more information regarding our method for recognizing revenue and expenses related to collaboration agreements, as well as Item 8. Note 17 for more information regarding our collaboration agreements). Recent Developments • We continue to experience a significant reduction in pricing expectations from historical levels in our RX segment due to competitive pressures. This softness in pricing is attributable to various factors, including increased focus from customers to capture supply chain productivity savings, competition in specific products, and consolidation of certain customers. We expect this softness to continue to impact the segment for the foreseeable future, and we are forecasting a high single digit pricing decline in this segment for the year ending December 31, 2018. • We are continuing our previously announced portfolio review process, which includes the ongoing comprehensive internal evaluation of the RX segment's market position, growth opportunities, and interdependencies with our manufacturing and shared service operations to determine if strategic alternatives should be explored related to this segment. • During the year ended December 31, 2017, we sold various ANDAs for a total gain of $23.0 million. 11 Products Listed below are some of the generic prescription products, including authorized generic and ORx® products, that we manufacture and/or distribute: Perrigo Company plc - Item 1 RX Generic Name (1) Adapalene cream Bacitracin ophthalmic ointment Benzoyl peroxide 5% - clindamycin 1% gel Budesonide Clindamycin foam Clindamycin phosphate and benzoyl peroxide gel Clobetasol foam, lotion and shampoo Desonide cream, ointment Dihydroergotamine injection Halobetasol ointment and cream Hydrocortisone suppositories Mupirocin ointment Nystatin topical powder Olopatadine nasal spray Permethrin cream Scopolamine patch Tacrolimus Testosterone 1% gel Testosterone cypionate injection Testosterone solution Triamcinolone acetonide nasal spray Triamcinolone cream/ointment Comparative Brand-Name Drug Differin® N/A BenzaClinTM Entocort® Evoclin® Duac® Olux®, Olux-E®, Clobex® Desonate®, Tridesilon® D.H.E. 45 Ultravate® N/A Bactroban® Mycostatin® Patanase® Elimite® TransdermScop® Protopic® Androgel Depo®, Testosterone Axiron® Nasacort® AQ Triderm™/Kenalog™ (1) Contains the same active ingredients present in the same dosage form as the comparable brand-name drug We launched a number of new RX products in the year ended December 31, 2017, most notably Scopolamine and Testosterone 2% topical (generic equivalent to Axiron®). During the year ended December 31, 2017, new product sales in the RX segment were $75.9 million. During the year ended December 31, 2017, we, on our own or in collaboration with partners, received final approval from FDA health authorities for 12 Rx drug applications, and as of December 31, 2017, we had 21 Rx drug applications pending approval. Sales and Marketing Our customers include major wholesalers, including Cardinal Health, McKesson, and AmerisourceBergen; sourcing groups such as Red Oak and ClarusOne; national and regional retail drug, supermarket and mass merchandise chains, including Walgreens Boots Alliance, Rite Aid, Walmart, CVS, Kroger, and Safeway; hospitals; and pharmacies. ORx® products are sold to the consumer through the pharmacy counter of predominantly the same retail outlets as our OTC pharmaceutical products. Competition The market for Rx products is subject to intense competition from other generic drug manufacturers, brand- name pharmaceutical companies launching their own generic version of their branded products (known as an authorized generic), manufacturers of branded drug products that continue to produce those products after patent expirations, and manufacturers of therapeutically similar drugs. Among our generic drug manufacturer competitors are Par Pharmeceuticals, Apotex Corp., Glenmark Generics Inc., Impax Laboratories, Inc., Mylan, Prasco, LLC, Sandoz, Sun Pharmaceuticals, Taro Pharmaceuticals, Teva Pharmaceutical Industries Ltd., and Akorn. 12 Perrigo Company plc - Item 1 RX We believe that one of our primary competitive advantages is our ability to introduce difficult to develop and/ or manufacture topical generic versions to brand-name drug products. Generally, these products are exposed to less competition due to the relatively longer and more expensive development, clinical trial, and approval processes. In addition, we believe we have a favorable competitive position due primarily to our efficient distribution systems, topical production economies of scale, customer service, and overall reputation (refer to Item 1A. Risk Factors - Risks Related to Operations for more information and risks associated with competition). SPECIALTY SCIENCES Overview The Specialty Sciences segment was comprised of assets focused on the treatment of multiple sclerosis, specifically in connection with the drug Tysabri® (natalizumab). We received contingent payments related to the Tysabri® financial asset until we disposed of it on March 27, 2017. We were entitled to contingent payments from Biogen Idec Inc. ("Biogen") based on its Tysabri® sales in all indications and geographies. We received contingent payments that were based on royalties of 12% on worldwide Biogen sales of Tysabri® from December 18, 2013 through April 30, 2014. As of May 1, 2014, we received royalties of 18% on annual worldwide Biogen sales of Tysabri® up to $2.0 billion and 25% on annual sales above $2.0 billion. The cash received from Biogen for the royalty percentage on Tysabri® sales was recorded as cash flows from investing activities in our Consolidated Statements of Cash Flow. We had recorded the Tysabri® royalty stream as a financial asset and elected to account for this asset using the fair value option method, which incorporates discounted cash flows related to the expected future cash flows to be received. We used significant judgment in determining our valuation inputs, including estimates as to the probability and timing of future sales of Tysabri®, as well as estimates of the expected future cash flows. The estimated fair value of the asset was subject to variation should those cash flows vary significantly from our estimates. We had performed evaluations at each reporting period to assess those estimates, discount rates utilized and general market conditions affecting fair value (refer to Item 8. Note 6). The Specialty Sciences segment also included ongoing obligations under the sale agreement between Biogen and Elan for 50% of losses and litigation expenses arising out of any Tysabri® product liability claims, required insurance coverage and related expenses. Effective January 1, 2017, due to the sale of the Tysabri® financial asset, all the above mentioned expenses were moved to unallocated expenses. On March 27, 2017, we announced the completed divestment of our Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017. We elected to account for the contingent milestone payments using the fair value option method, and these were recorded at an estimated fair value of $134.5 million as of December 31, 2017 (refer to Item 8. Note 6 and Item 1A. Risk Factors - Risks Related to Operations). OTHER Recent Developments We had an Other segment that was primarily comprised of sales of API products, which did not meet the quantitative threshold required to be a separate reportable segment. We developed, manufactured, and marketed API products, which were used worldwide by both generic and branded pharmaceutical companies. Certain of these ingredients were used in our own pharmaceutical products. The manufacturing of API occurred primarily in Israel with some production in India. 13 Perrigo Company plc - Item 1 Other On April 6, 2017, we completed the sale of our India API business to Strides Shasun Limited. We received $22.2 million of proceeds, inclusive of an estimated working capital adjustment, which resulted in an immaterial gain recorded in Other expense (Income), net on the Consolidated Statements of Operations. Prior to closing the sale, we determined that the carrying value of the India API business exceeded its fair value less the cost to sell, resulting in an impairment charge of $35.3 million, which was recorded in Impairment charges on the Consolidated Statements of Operations for the year ended December 31, 2016 (refer to Item 8. Note 2). On November 21, 2017, we completed the sale of our Israel API business, which was previously classified as held-for-sale to SK Capital, for a sale price of $110.0 million, which resulted in an immaterial gain recorded in Other expense (Income), net on the Consolidated Statements of Operations (refer to Item 8. Note 2 and Note 6). INFORMATION APPLICABLE TO ALL REPORTABLE SEGMENTS Research and Development R&D is a key component of our business strategy and is performed in various locations in the countries in which we operate. While we conduct a significant amount of our own R&D, we also enter into strategic alliance agreements to obtain the rights to manufacture and/or distribute new products. R&D investments were $167.7 million for the year ended December 31, 2017 (refer to Item 8. Note 17). During the years ended December 31, 2017 and December 31, 2016, we wrote off capitalized in-process research and development from previous acquisitions totaling $12.7 million and $3.5 million, respectively, due to changes in the projected development and regulatory timelines for various projects. The year ended December 31, 2017 included R&D expense related to new product development and clinical trial expenses in our CHCA, CHCI and RX segments. The year ended December 31, 2016 included R&D expense related to clinical trial expenses primarily in our CHCA and RX segments. The six months ended December 31, 2015 included incremental R&D expense due to the Omega acquisition. The six months ended December 27, 2014 included a $10.0 million payment made in connection with our entry into a collaboration arrangement. The year ended June 27, 2015 also included incremental R&D expense due to the Omega acquisition, as well as the payment made in relation to the collaboration arrangement noted above, and an R&D contractual arrangement under which we funded $18.0 million of R&D. We anticipate that R&D expenditures will increase as a percentage of net sales for the foreseeable future as we continue to cultivate our presence in the Rx-to-OTC switch and generic pharmaceutical markets, and develop our internal R&D capabilities (refer to Item 1A. Risk Factors - Risks Related to Operations for risks associated with innovation and R&D). Trademarks and Patents While we own certain trademarks and patents, neither our business as a whole, nor any of our segments, is materially dependent upon our ownership of any one trademark, or patent, or group of trademarks or patents. Materials Sourcing Affordable high quality raw materials and packaging components are essential to all of our business units due to the nature of the products we manufacture. Raw materials and packaging components are generally available from multiple suppliers. Supplies of certain raw materials, bulk tablets, and components may be more limited, as they are available from one or only a few suppliers and may require regulatory approval before we can use them. Prior to the sale of our Israel and India API businesses, we had the ability to manufacture and supply certain API for our OTC and Rx products, which we now source from the companies that have acquired our API business. We have been purchasing an increasing number of components and select finished goods rather than manufacturing them because of the availability of goods, economic reasons, temporary production limitations, FDA restrictions, sale of our API business, and other factors. Historically, we have been able to react effectively to situations that require alternate sourcing. Should such alternate sourcing be necessary, FDA requirements placed on products approved through the ANDA or NDA 14 Perrigo Company plc - Item 1 process could substantially lengthen the approval of an alternate source and adversely affect financial results. We believe we have good, cooperative working relationships with substantially all of our suppliers and have historically been able to capitalize on economies of scale in the purchase of materials and supplies due to our volume of purchases (refer to Item 1A. Risk Factors - Risks Related to Operations for risks associated with materials sourcing). Manufacturing and Distribution Our primary manufacturing facilities are in the U.S. We also have manufacturing facilities in the U.K., Belgium, France, Germany, Austria, Israel, Mexico, and Australia, along with a joint venture in China (refer to Item 1A. Risk Factors - Risks Related to Operations for risks associated with our manufacturing facilities). We supplement our production capabilities with the purchase of products from outside sources. The capacity of some facilities may be fully utilized at certain times for various reasons, such as customer demand, the seasonality of the cough/cold/flu, allergy, or flea and tick seasons, and new product launches. We may utilize available capacity by performing contract manufacturing for other companies. We have logistics facilities in the U.S., Israel, Mexico, Australia, and numerous locations throughout Europe. We use contract freight and common carriers to deliver our products. Significant Customers Our primary customer base aligns with the concentration of large drug retailers in the current global retail drug industry marketplace. Walmart is our largest customer and accounted for the following percentage of consolidated net sales: Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 December 27, 2014 June 27, 2015 13% 13% 13% 19% 16% Sales to Walmart are primarily in the CHCA segment. As a percentage of our total U.S. OTC sales, our sales to Walmart generally align with Walmart's U.S. retail market share in the products we sell to them. In addition, while no other customer individually comprises more than 10% of net sales, we do have other significant customers. We believe we generally have good relationships with all of our customers (refer to Item 1A. Risk Factors - Risks Related to Operations for risks associated with customers). Environmental We are subject to various environmental laws and regulations. We have made, and continue to make, expenditures necessary to comply with applicable environmental laws, but do not believe that the costs for complying with such laws and regulations have been or will be material to our business. We do not have any material remediation liabilities outstanding. While we believe that climate change could present risks to our business, including increased operating costs due to additional regulatory requirements, physical risks to our facilities, water limitations, and disruptions to our supply chain, we do not believe these risks are material to our business in the near term. Corporate Social Responsibility We are committed to doing business in an ethical manner. We have a long history of environmentally sound and efficient operations, safe and healthy working conditions, and active participation in the communities where we are located. As reflected in our Corporate Social Responsibility Commitment Statement available on our website, we remain committed to: • Helping consumers access safe, effective and affordable healthcare products; • Strong corporate governance; • Complying with regulatory and legal requirements; • Demonstrating environmental stewardship; 15 Perrigo Company plc - Item 1 • Continuously improving packaging sustainability; • Protecting human rights of our global employees and challenging our partners to do the same; • Diversity of thought, experience and perspective; • Providing a safe and healthy work environment for our employees; and • Establishing effective community partnerships. Through these efforts, we strive to minimize our impact on the environment, drive responsible business practices, and ensure the welfare of our employees, their families, and the communities in which we operate now and into the future. GOVERNMENT REGULATION AND PRICING The manufacturing, processing, formulation, packaging, labeling, testing, storing, distributing, advertising, and sale of our products are subject to regulation by a variety of agencies in the localities in which our products are sold. In addition, we manufacture and market certain of our products in accordance with standards set by various organizations. We believe that our policies, operations, and products comply in all material respects with existing regulations to which we are subject (refer to Item 1A. Risk Factors - Risks Related to Operations for related risks). United States Regulation U.S. Food and Drug Administration The FDA has jurisdiction over our Rx, OTC drug products, API, and Infant Formula Foods. The FDA’s jurisdiction extends to the manufacturing, testing, labeling, packaging, storage, distribution, and promotion of these products. We are committed to consistently providing our customers with high quality products that adhere to "current Good Manufacturing Practices" ("cGMP") regulations promulgated by the FDA. OTC and Rx Pharmaceuticals All facilities where Rx and OTC products are manufactured, tested, packaged, stored, or distributed for the U.S. market must comply with FDA cGMPs and regulations promulgated by competent authorities in the countries, states and localities where the facilities are located. All of our drug products are manufactured, tested, packaged, stored, and distributed according to cGMP regulations. The FDA performs periodic audits to ensure that our facilities remain in compliance with all appropriate regulations. Many of our OTC products are regulated under the OTC monograph system and subject to certain FDA regulations. Under this system, selected OTC drugs are generally recognized as safe and effective and do not require the approval of an ANDA or NDA prior to marketing. Products marketed under the OTC monograph system must conform to specific quality, formula, and labeling requirements, including permitted indications, required warnings and precautions, allowable combinations of ingredients, and dosage levels. It is generally less costly to develop and bring to market a product regulated under the OTC monograph system. We also market generic prescription drugs and non-prescription products that have switched from prescription to OTC status. Prior to commercial marketing, these products require approval by the FDA of an ANDA or NDA that provides information on chemistry, manufacturing controls, clinical safety, efficacy and/or bioequivalence, packaging, and labeling. While the development process for these drugs generally requires less time and expense than the development process of a new drug, the size and duration of required studies can vary greatly. Prior to the onset of the Generic Drug User Fee Amendments of 2012 (“GDUFA”), the FDA approval of generic drug applications took approximately three to five times longer than approval of innovator drugs. Pursuant to GDUFA II, beginning October 1, 2017, year five of the program, the FDA pledged to complete a first cycle review on 90% of electronic generic applications within 10 months of submission. Under the Federal Food, Drug and Cosmetic Act, as amended ("FFDCA") (the Hatch-Waxman amendments), a company submitting an NDA can obtain a three-year period of marketing exclusivity for a prescription or OTC product if it performs a clinical study that is essential to FDA approval. Longer periods of exclusivity are possible for new chemical entities, orphan drugs (those designated under section 526 of the FFDCA) and drugs under the Generating Antibiotic Incentives Now Act. During this exclusivity period, the FDA cannot 16 Perrigo Company plc - Item 1 Regulation approve any ANDAs for a similar or equivalent generic product, which can preclude another party from marketing a similar product during this period. A company may obtain an additional six months of exclusivity if it conducts pediatric studies requested by the FDA on the product. This exclusivity can delay both the FDA approval and sales of certain products. A company may be entitled to a 180-day generic exclusivity period for certain products. This exclusivity period often follows a patent certification and litigation process whereby the product innovator may sue for infringement. The legal action does not ordinarily result in material damages, but it generally triggers a statutorily mandated delay in FDA approval of the ANDA for a period of up to 30 months from when the innovator was notified of the patent challenge. The Food and Drug Administration Safety and Innovation Act ("FDASIA") was signed into law on July 9, 2012. The law established, among other things, new user fee statutes for generic drugs and biosimilars, FDA authority concerning drug shortages, changes to enhance the FDA's inspection authority of the drug supply chain, and a limited extension of the 30-month stay provision described above. The FDASIA also reduced the time required for FDA responses to generic-blocking citizen petitions. We implemented new systems and processes to comply with the new facility self-identification and user fee requirements of the FDASIA, and we monitor facility self- identification and fee payment compliance to mitigate the risk of potential supply chain interruptions or delays in regulatory approval of new applications. The U.S. government's Federal Drug Supply Chain Security Act ("DSCSA") requires development of an electronic pedigree to track and trace each prescription drug at the salable unit level through the distribution system, which will be effective incrementally over a 10-year period. The serialization of all Rx products distributed in the U.S. needed to be completed by November 26, 2018, with the requirement for tracking the products commencing on November 27, 2023. Requirements for the tracing of products at the lot level through the pharmaceutical distribution supply chain went into effect on January 1, 2015 for manufacturers, wholesale distributors, and re-packagers, and on July 1, 2015 for dispensers. Infant Formula and Foods The FDA’s Center for Food Safety and Applied Nutrition is responsible for the regulation of infant formula. The Office of Nutrition, Labeling and Dietary Supplements ("ONLDS") has labeling responsibility for infant formula, while the Office of Food Additive Safety ("OFAS") has program responsibility for food ingredients and packaging. The ONLDS evaluates whether an infant formula manufacturer has met the requirements under the FFDCA and consults with the OFAS regarding the safety of ingredients in infant formula and of packaging materials for infant formula. All manufacturers of pediatric nutrition products must begin with safe food ingredients, which are either generally recognized as safe or approved as food additives. The Infant Formula Act provides specific requirements for infant formula to ensure the safety and nutrition of infant formulas, including minimum and, in some cases, maximum levels of specified nutrients. Before marketing a particular infant formula, the manufacturer must provide regulatory agencies assurance of the nutritional quality of that particular formulation consistent with the FDA’s labeling, nutrient content, and manufacturer quality control requirements. A manufacturer must notify the FDA at least 90 days before the marketing of any infant formula that differs fundamentally in processing or in composition from any previous formulation produced by the manufacturer. We actively monitor this process and make the appropriate adjustments to remain in compliance with recent FDA rules regarding cGMP, quality control procedures, quality factors, notification requirements, and reports and records for the production of infant formulas. In addition, the FFDCA requires infant formula manufacturers to test product composition during production and shelf-life; to keep records on production, testing, and distribution of each batch of infant formula; to use cGMP and quality control procedures; and to maintain records of all complaints and adverse events, some of which may reveal the possible existence of a health hazard. The FDA conducts yearly inspections of all facilities that manufacture infant formula, inspects new facilities during early production runs, and collects and analyzes samples of infant formula. Our infant formula manufacturing facilities have been inspected by the FDA after the effective date of the final rule and found to be in full compliance with the new GMP regulations with no corrective actions required. 17 Perrigo Company plc - Item 1 Regulation Our infant and toddler foods are subject to the Food Safety Modernization Act ("FSMA"), which protects the safety of U.S. foods by mandating comprehensive, prevention-based controls within the food industry. Under FSMA, the FDA has mandatory recall authority for all food products and greater authority to inspect food producers and is taking steps toward product tracing to enable more efficient product source identification in the event of a safety issue. Active Pharmaceutical Ingredients Third parties develop and manufacture API for use in certain of our products that are exported to the U.S. and other global markets. Before API can be commercialized in the U.S., the manufacturer and/or developer must submit a drug master file ("DMF") that provides the proprietary information related to the manufacturing process. The FDA inspects the manufacturing facilities to assess cGMP compliance, and the facilities and procedures must be cGMP compliant before API may be exported to the U.S. The facilities and products are subject to regulation by the applicable regulatory bodies in the place of manufacture as well as the regulatory agency in the country from which the product is exported or imported. For API exported to European markets, the manufacturer must submit a European DMF and, where applicable, obtain a certificate of suitability from the European Directorate for the Quality of Medicines. The manufacturing facilities and production procedures for API marketed in Europe must meet EU-GMP and European Pharmacopeia standards. U.S. Department of Agriculture The Organic Foods Production Act enacted under Title 21 of the 1990 Farm Bill established uniform national standards for the production and handling of foods labeled as "organic." Our infant formula manufacturing sites in Vermont and Ohio adhere to the standards of the U.S. Department of Agriculture ("USDA") National Organic Program for production, handling, and processing to maintain the integrity of organic products. Our infant formula manufacturing sites in Vermont and Ohio are USDA-certified, enabling them to produce and label organic products for U.S. and Canadian markets. U.S. Environmental Protection Agency The U.S. Environmental Protection Agency ("EPA") is the main regulatory body in the United States for veterinary pesticides. The EPA's Office of Pesticide Programs is responsible for the regulation of pesticide products applied to animals. All manufacturers of animal health pesticides must show that their products will not cause “unreasonable adverse effects to man or the environment” as stated in the Federal Insecticide, Fungicide, and Rodenticide Act. Within the U. S., pesticide products that are approved by the EPA must also be approved by individual state pesticide authorities before distribution in that state. Post-approval monitoring of products is required, with reports provided to the EPA and some state regulatory agencies. U.S. Drug Enforcement Administration The U.S. Drug Enforcement Administration ("DEA") regulates certain drug products containing controlled substances, such as morphine, hydromorphone, opium, testosterone, midazolam, and List I chemicals, such as pseudoephedrine, pursuant to the federal Controlled Substances Act ("CSA"). The CSA and DEA regulations impose registration, security, record keeping, reporting, storage, manufacturing, distribution, importation and other requirements upon legitimate handlers under the oversight of the DEA. The DEA categorizes controlled substances into Schedules I, II, III, IV, or V, with varying qualifications for listing in each schedule. We are subject to the requirements regarding the controlled substances in Schedules II - V and the List I chemicals. Our facilities that manufacture, distribute, import, or export any controlled substances must register annually with the DEA. 18 Perrigo Company plc - Item 1 Regulation The DEA inspects all manufacturing facilities to review security, record keeping, reporting, and handling prior to issuing a controlled substance registration, and it also periodically inspects facilities for compliance with the CSA and its regulations. Failure to maintain compliance with applicable requirements, particularly as manifested in the loss or diversion of controlled substances, can result in enforcement action, such as civil penalties, refusal to renew necessary registration, or the initiation of proceedings to revoke those registrations. In certain circumstances, violations could lead to criminal prosecution. We are also subject to state laws regulating the manufacture and distribution of certain products. Federal Healthcare Programs and Drug Pricing Regulation Within the U.S., government healthcare insurance and welfare programs such as the Medicare and Medicaid programs are important third party payers for patients who take our products. These programs include several indirect forms of price regulation applicable to our drug products as a condition to coverage and/or payment for our products, and also regulate the amount that pharmacies and other healthcare providers will be paid for our products. Specifically, U.S. law requires that a pharmaceutical manufacturer, as a condition of having federal funds being made available for the manufacturer’s drugs under Medicaid and Medicare Part B, enter into three government pricing program agreements: (i) a Medicaid rebate agreement with the Secretary of Health and Human Services (“HHS”) to pay rebates to state Medicaid programs for the manufacturer’s covered outpatient drugs that are dispensed to Medicaid beneficiaries and paid for by a state Medicaid program; (ii) a 340B program agreement with the Secretary of HHS to provide discounts to certain “covered entity” safety net healthcare providers; and (iii) a Master Agreement with the Department of Veterans Affairs ("VA") under which discounts are available for purchases by federal agencies. We have such agreements in effect. Medicaid Rebate Agreement The Medicaid rebate agreement requires the drug manufacturer to remit rebates to each state Medicaid agency on a quarterly basis for both fee-for-service and Medicaid managed care organization utilization. Rebate amounts are based on pricing data reported by the manufacturer to the Centers for Medicare & Medicaid Services (“CMS”), including Average Manufacturer Price ("AMP") and, in the case of innovator products, Best Price ("BP"). U.S. law also requires that a company that participates in the Medicaid rebate program report average sales price ("ASP") information to CMS for each calendar quarter for certain categories of drugs that are paid under Part B of the Medicare program. CMS uses these submissions to determine payment rates for drugs under Medicare Part B. Under the Medicaid rebate program, the minimum rebate amounts due are as follows: (i) for noninnovator products, in general generic drugs marketed under ANDAs, the rebate amount is 13% of the AMP for the quarter; and (ii) for innovator products, in general brand-name products marketed under NDAs, the rebate amount is the greater of 23.1% of the AMP for the quarter or the difference between such AMP and the BP for that same quarter. Manufacturers also pay an “additional rebate" on innovator drugs where price increases since launch have outpaced inflation. Beginning with the first quarter of 2017, an additional rebate is due for noninnovator products, which is calculated somewhat differently from the innovator product additional rebate, but likewise generally applies where and to the extent that a manufacturer’s AMP increases faster than the rate of inflation. CMS issued a final regulation, generally effective April 1, 2016, to implement changes to the Medicaid rebate program under the 2010 health reform legislation (“Health Reform Law”) and otherwise to provide program guidance. In addition to guidance concerning rebate program administration matters, the regulation also addressed certain related Medicaid reimbursement matters. First, under the Health Reform Law, CMS has also begun to use manufacturer AMP data to calculate reimbursement limits for pharmacies for multiple source drugs under the Medicaid program, known as the federal upper limits ("FULs"). CMS also surveys and publishes retail community pharmacy acquisition cost information to provide state Medicaid agencies with a basis for comparing their own reimbursement and pricing methodologies and rates. Second, the regulation also directed states to update their Medicaid payment methodologies to provide for payment amounts designed to reflect pharmacies’ "actual acquisition costs" for drugs, a change from the prior "estimated acquisition" standard. The regulation also required states to provide the government with findings to support their compliance with this standard by April 1, 2017. Pricing and rebate calculations are governed by statutory and regulatory requirements that are complex, vary among products and programs, can change over time, and are subject to interpretation by us, governmental or regulatory agencies, and the courts. In the case of the Medicaid rebate program, if we become aware of errors in 19 Perrigo Company plc - Item 1 Regulation our prior price submissions, or a prior BP submission needs to be updated due to late arriving data, we must resubmit the updated data within specified time frames. Such restatements and recalculations increase our cost of compliance with the Medicaid rebate program, and corrections can result in an overage or underage of our rebate liability for past quarters, depending on the nature of the correction. 340B Program Agreement The 340B drug pricing program requires participating manufacturers to agree to charge statutorily-defined covered entities no more than the 340B “ceiling price” for the manufacturer’s covered outpatient drugs. The ceiling price is derived from the data the manufacturer reports under the Medicaid rebate program and therefore any changes to statutory or regulatory requirements applicable to the Medicaid price figures may impact the 340B ceiling price calculation as well. 340B covered entities include a variety of community health clinics and other entities that receive health services grants from the Public Health Service, as well as certain hospitals that serve a disproportionate share of low-income patients. Master Agreement with the Department of Veterans Affairs U.S. law also requires any company that participates in the Medicaid rebate program and Medicare Part B and that wants its covered drugs paid for by certain federal agencies and grantees to enter into a Master Agreement with the VA. Under the Master Agreement, the company must offer its innovator drugs for procurement under the Federal Supply Schedule (“FSS”) contracting program, and must charge certain agencies (VA, Department of Defense, Public Health Service and the Coast Guard) no more than a statutory Federal Ceiling Price (“FCP”). The FCP is calculated based on Non-Federal Average Manufacturer Price (“NFAMP”) data we submit to the VA. FSS contracts include extensive disclosure and certification requirements and standard government terms and conditions with which we must comply. Consistent with VA’s interpretation of the Master Agreement, we have also entered into an agreement to pay rebates on covered drug prescriptions dispensed to TRICARE beneficiaries by TRICARE network retail pharmacies. Medicare Part D “Coverage Gap” Rebates For certain innovator products, manufacturers must also enter into an agreement with the Secretary of HHS to provide rebates with respect to utilization of their products by certain Medicare Part D beneficiaries while those patients are within the Medicare Part D benefit “coverage gap.” Manufacturers are not required to submit separate pricing data under this program; the rebate amount is calculated by CMS based on Part D plans’ “negotiated prices” paid to pharmacies. Other Price Regulation In addition to these technical government pricing regulation programs, drug pricing has come under increasing public scrutiny arising out of general concerns about high drug costs or price increases, and transparency of pricing and discounting practices within the pharmaceutical distribution system. Several states, including Maryland, Nevada, and California, have recently enacted laws that prohibit “price gouging,” require manufacturers to report certain information concerning price increases exceeding certain amounts, and/or provide advance notice of price increases to certain entities (refer to Item 1A. Risk Factors - Risks Related to Operations for risks related to the above-mentioned programs). Other U.S. Regulations and Organizations We are subject to various other federal, state, non-governmental, and local agency rules and regulations. Compliance with the laws and regulations regarding the manufacture and sale of our current products and the discovery, development, and introduction of new products requires substantial effort, expense and capital investment. Other regulatory agencies, organizations, legislation, regulation and laws that may impact our business include, but are not limited to: • Physician Payment Sunshine Act - This act requires certain pharmaceutical manufacturers to engage in extensive tracking of payments or transfers of value to physicians and teaching hospitals, maintenance of a payment database and public reporting of the payment data. 20 Perrigo Company plc - Item 1 Regulation • Foreign Corrupt Practices Act of 1977 ("FCPA") - This act and other similar anti-bribery laws prohibit companies and their intermediaries from providing money or anything of value to officials of foreign governments, foreign political parties or international organizations with the intent to obtain or retain business or seek a business advantage. • Federal Trade Commission ("FTC") - This agency oversees the advertising and other promotional practices of consumer products marketers. The FTC considers whether a product’s claims are substantiated, truthful and not misleading. The FTC also reviews mergers and acquisitions of companies exceeding specified thresholds and investigates certain business practices relevant to the healthcare industry. • International Organization for Standardization ("ISO") - The ISO Standards specify requirements for a Quality Management System that demonstrates the ability to consistently provide products that meet customer and applicable regulatory standards and includes processes to ensure continuous improvement. Our infant formula manufacturing sites are ISO 9001-2008 Certified for Quality Management Systems. ISO inspections are conducted at least annually. • United States Pharmacopeial Convention, Inc. ("USP") - The USP is a non-governmental, standard-setting organization. By reference, the FFDCA incorporates the USP quality and testing standards and monographs as the standard that must be met for the listed drugs, unless compliance with those standards is specifically disclaimed on the product’s labeling. USP standards exist for most Rx and OTC pharmaceuticals and many nutritional supplements. The FDA typically requires USP compliance as part of cGMP compliance. • Health Insurance Portability and Accountability Act ("HIPAA") - We could be subject to criminal penalties if we knowingly obtain individually identifiable health information from a covered entity in a manner that is not authorized or permitted by HIPAA or for aiding and abetting the violation of HIPAA. • Consumer Product Safety Commission ("CPSC") - The CPSC has published regulations requiring child resistant packaging on certain products including pharmaceuticals and dietary supplements. The manufacturer of any product that is subject to any CPSC rule, ban, standard or regulation must certify that, based on a reasonable testing program, the product complies with CPSC requirements. • Anti-Bribery Laws - Various jurisdictions in which we operate have laws and regulations, including the U.K. Bribery Act 2010, aimed at preventing and penalizing corrupt and anticompetitive behavior. • Other State Agencies - We are subject to regulation by numerous other state health departments, insurance departments, boards of pharmacy, state controlled substance agencies, state consumer health and safety regulations, and other comparable state agencies, each of which have license requirements and fees that vary by state. Regulation Outside the U.S. We develop and manufacture products and market third-party manufactured products in regions outside the U.S., including Eastern and Western Europe, Israel, Mexico, Australia, countries in Asia, South America, and the Middle East, each of which has its own regulatory environment. The majority of our sales outside the U.S. are in the following categories: OTC/Rx pharmaceuticals, medical devices, dietary supplements and cosmetics. Other regulatory agencies, organizations and legislation that may impact our business include, but are not limited to: • Privacy Regulations - We are subject to numerous global laws and regulations designed to protect personal data, such as the European Union Directive on Data Protection (which will be replaced by the European Union General Data Protection Regulation (“GDPR”) from May 2018 onward). The GDPR will introduce more stringent data protection requirements in the European Union ("EU"), as well as substantial fines for breaches of the data protection rules. The GDPR will increase our responsibility and potential liability in relation to personal data that we process, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR. 21 • Transparency Laws - In various jurisdictions in which we operate, we are subject to the laws and regulations aimed at increasing transparency of financial relationships between healthcare professionals and pharmaceutical/medical device manufacturers. Perrigo Company plc - Item 1 Regulation European Union OTC and Rx Pharmaceuticals The European pharmaceutical industry is highly regulated and much of the legislative and regulatory framework is driven by the European Parliament and the European Commission. This has many benefits, including the potential to harmonize standards across the complex European market. However, obtaining regulatory agreement across member states presents complex challenges that can lead to delays in the regulatory process. In the EU, as well as many other locations around the world, the manufacture and sale of medicinal products are regulated in a manner substantially similar to that of the U.S. requirements, which generally prohibit the handling, manufacture, marketing, and importation of any medicinal product unless it is properly registered in accordance with applicable law. The registration file relating to any particular product must contain data related to product efficacy and safety, including results of clinical testing and/or references to medical publications, as well as detailed information regarding production methods and quality control. Health ministries are authorized to cancel the registration of a product if it is found to be harmful or ineffective or if it is manufactured or marketed other than in accordance with registration conditions. Between 1995 and 1998, the over-arching regulation that governs medicinal products was revised in an attempt to simplify and harmonize product registration. This revised legislation introduced the mutual recognition procedure (“MRP”), whereby after approval of a marketing authorization by regulatory authorities in the reference member state (“RMS”), additional marketing authorizations could be submitted to other concerned member states to obtain a product license. In November 2005, the medicinal product legislation was further revised to introduce the decentralized procedure (“DCP”), whereby marketing authorizations are submitted simultaneously to the RMS and select concerned member states. In 2005, the EMA also opened up the centralized procedure to sponsors of marketing authorizations for generic medicinal products. Unlike the MRP and DCP, the centralized procedure results in a single marketing authorization and product labeling across all member states that will allow a sponsor to file for individual country reimbursement and make the medicine available in all the EU countries listed on the application. Marketing authorizations and subsequent product licenses are granted to applicants only after the relevant health authority issues a positive assessment of quality, safety and efficacy of the product. In addition to obtaining marketing authorization for each product, all member states require that a manufacturer’s facilities obtain approval from an EU Regulatory Authority. The EU has a code of GMP that each manufacturer must follow and comply with. Regulatory authorities in the EU may conduct inspections of the manufacturing facilities to review procedures, operating systems and personnel qualifications. We believe that our policies, operations and products comply in all material respects with existing regulations to which our operations are subject. EU Member States had to transpose the European Falsified Medicines Directive (the “Directive”) into national law by January 2, 2013. The transposition process is now complete. The provisions of the Directive are intended to reduce the risk of counterfeit medicines entering the supply chain and also to ensure the quality of API manufactured outside of the EU. The Directive required the serialization of all Rx and some OTC products, similar to the DSCSA in the U.S. In the EU, member states regulate the pricing of prescription medicinal products, and in some cases, the formulation and dosing of products. This regulation is handled by individual member state national health services. These individual regulatory bodies can result in considerable price differences and product availability among member states. The implementation of tendering systems for the pricing of pharmaceuticals in several countries generally impacts drug pricing for generics; generally “tendering” refers to a system that requires bids to be submitted to the government by competing manufacturers to be the exclusive, or one of a few, suppliers of a product in a particular country. Data exclusivity provisions exist in many countries, although the application is not uniform. In general, these exclusivity provisions prevent the approval and/or submission of generic drug applications to the health authorities 22 Perrigo Company plc - Item 1 Regulation for a fixed period of time following the first approval of the brand-name product in that country. As these exclusivity provisions operate independently of patent exclusivity, they may prevent the submission of generic drug applications for some products even after the patent protection has expired. The requirements deriving from European pharmacovigilance regulation are constantly expanding due to increasing guidance on good vigilance practices and increased communication on inspectors’ expectations. Pharmacovigilance fee regulation became effective in late 2014 to support health authority assessment of pharmacovigilance safety evaluation reports, study protocols for post authorization safety studies and referrals. Once approved, the advertising of pharmaceuticals in the EU is governed by national regulations and guidelines. Within certain member states this is overseen by a self-certification process whereas in others national governance bodies approve material prior to release. The wholesale distribution of medicinal products is an important activity in the integrated supply chain management. The quality and the integrity of medicinal products can be affected by a lack of adequate control. To this end, the EU Commission has published guidelines on Good Distribution Practice of medicinal products for human use in 2013. The present guidelines are based on Articles 84 and 85b(3) of medicinal products for human use directive. Medical Devices The EU has enacted into law numerous directives and adopted many harmonizing standards pertaining to a wide range of industrial products, including medical devices. Medical devices that comply with the requirements of applicable directives are entitled to bear the CE marking of conformity, which indicates that the device conforms to the applicable requirements of the directives and, accordingly, can be commercially distributed throughout Europe. The method of assessing conformity varies depending on the class of the product, but normally involves a combination of self-assessment by the manufacturer and a third-party assessment by a Notified Body, an organization accredited by a member state. Assessment by a Notified Body includes an audit of the manufacturer’s quality system and may also include specific testing of the product. This assessment is a prerequisite for a manufacturer to commercially distribute the product throughout the EU. Dietary Supplements Dietary supplements are subject to several regulations that inform the selection of ingredient levels and how products can be described on packaging and in advertising. These regulations include: Food Supplements Directive 2002/46/EC, Food Information to Consumers Regulation (EU) No 1169/2011, Permitted Vitamins and Minerals Regulation (EC) 1170/2009, Food Additives Regulation (EC) 1333/2008, Nutritional & Health Claims Regulation (EC) No 1924/2006, the Foods Intended for Particular Nutritional Uses Directive 2009/39/EC, and Regulation (EU) 609/2013. EU rules on nutrition and health claims, which were established by Regulation EC 1924/2006, apply to any nutritional or health claim by a manufacturer. The objective of the regulation is to ensure that claims made in food labeling or advertising are clear, accurate and based on scientific evidence. The European Food Safety Authority, an advisory panel to the European Commission, performs all scientific assessments of health claims on food and supplement labels. An EU register of nutrition and health claims exists to document approved, pending, and rejected claims. Cosmetics Cosmetic products in the EU market must comply with Regulation EC No. 1223/2009. This regulation requires manufacturers to prepare a product safety report prior to placing a cosmetic product in the market. In addition, for each cosmetic product placed in the market, a “responsible person” must be designated to oversee compliance with the regulation’s reporting requirements. Commission Regulation EU No. 655/2013 establishes the common criteria and justification for claims to be used in the packaging and advertising of cosmetics products. 23 Perrigo Company plc - Item 1 Employees As of December 31, 2017, we had approximately 10,400 full-time and temporary employees worldwide, of which approximately 24% were covered by collective bargaining agreements. We consider our employee relations generally satisfactory. Available Information Our principal executive offices are located at Treasury Building, Lower Grand Canal Street, Dublin 2, Ireland, and our North American base of operations is located at 515 Eastern Avenue, Allegan, Michigan 49010. Our telephone number is +353 1 7094000. Our website address is www.perrigo.com, where we make available free of charge our reports on Forms 10-K, 10-Q and 8-K, including any amendments to these reports, as soon as reasonably practicable after they are electronically filed with or furnished to the U.S. Securities and Exchange Commission ("SEC"). These filings are also available to the public at www.sec.gov and www.isa.gov.il. ITEM 1A. RISK FACTORS Risks Related to Operations We face vigorous competition from other pharmaceutical and consumer goods companies that may threaten the commercial acceptance and pricing of our products. We operate in a highly competitive environment. Our products compete against store brand, generic, and branded pharmaceuticals. Competition is also impacted by changes in regulations and government pricing programs that may give competitors an advantage. • As a manufacturer of generic versions of brand-name drugs through our CHCA and RX segments, we experience competition from brand-name drug companies that may try to prevent, discourage or delay the use of generic versions through various measures, including introduction of new branded products, legislative initiatives, changing dosage forms or dosing regimens, regulatory processes, filing new patents or patent extensions, lawsuits, citizens’ petitions, and negative publicity prior to introduction of a generic product. In addition, brand-name competitors may lower their prices to compete with generic products, increase advertising, or launch, either through an affiliate or licensing arrangements with another company, an authorized generic at or near the time the first generic product is launched, depriving the generic product potential market exclusivity. • Our CHCA and RX segments may experience increased price competition as other generic companies produce the same product, sometimes for dramatically lower margins in order to gain market share. Other generic companies may introduce new drugs and/or drug delivery techniques that make our current products less desirable. A drug may be subject to competition from alternative therapies during the period of patent protection or regulatory exclusivity, and thereafter, we may be subject to further competition from generic products or biosimilars. • The pharmaceutical industry is consolidating. This creates larger competitors and places further pressure on prices, development activities, and customer retention. Our animal health category within the CHCA segment has seen an increase in direct to consumer advertising by several branded competitors, which may increase in the future, and our nutritionals category has experienced increased competition through alternative channels such as health food stores, direct mail and direct sales. • We develop and distribute branded products primarily through our CHCI segment. We experience competition from other brand-name drug companies, many of which are larger and have more resources to devote to advertising and marketing. These direct competitors may be able to adapt more quickly to changes in customer requirements. Our current and future competitors may develop products comparable or superior to those offered by us at more competitive prices. 24 Perrigo Company plc - Item 1A Risk Factors • Our CHCA and RX segments also experience competition from our generic competitors, some of whom are significantly larger than we are, who may develop their products more rapidly or complete regulatory approval processes sooner, or may market their products earlier than we do. • If we are unable to compete successfully, our business will be harmed through loss of customers or increased negative pricing pressure that would adversely affect our ability to generate revenue and adversely affect our operating results. If we do not continue to develop, manufacture, and market innovative products that meet customer demands, we may lose market share and our net sales may be negatively impacted. Our continued growth is due in large part to our ability to develop, manufacture, and market products that meet customer requirements for quality, safety, efficacy, and cost effectiveness. Continuous introductions of new products and product categories are critical to our business. If we do not continue to develop, manufacture, and market new products, we could lose market share, and our net sales may be negatively impacted. See Item 1. Business - Research and Development for more information. • We maintain a diversified product line to function as a primary supplier for our customers. Capital investments are driven by growth, technological advancements, cost improvement and the need for manufacturing flexibility. Our future capital expenditures could vary materially due to the uncertainty of these factors. In addition, if we fail to stay current with the latest manufacturing, information and packaging technology, we may be unable to competitively support the launch of new product introductions. • Our product margins may decline over time due to our products' aging life cycles, changes in consumer choice, changes in competition for our existing products, or the introduction of next generation innovative products; therefore, new product introductions are necessary to maintain our current financial condition. If we are unable to continue to create new products, we may lose market share or experience pricing pressure, and our net sales may be negatively impacted. • We must prove that the regulated generic drug products in our CHCA and RX segments are bioequivalent to their branded counterparts, which may require bioequivalence studies, and in the case of topical products, even more extensive clinical endpoint trials to demonstrate their efficacy. The development and commercialization process, particularly with respect to innovative products, is both time consuming and costly, and subject to a high degree of business risk. Products currently under development may require re- design to meet evolving FDA standards, may not perform as expected, may not pass required bioequivalence studies, or may be the subject of intellectual property challenges. Necessary regulatory approvals may not be obtained in a timely manner, if at all. Any of these events may negatively impact our net sales. • Even if we are successful in developing a product, our customers' failure to launch one of our products successfully, or delays in manufacturing developed products, could adversely affect our operating results. In addition, the FDA or similar regulatory agency could impose higher standards and additional requirements, such as requiring more supporting data and clinical data than previously required, in order to gain regulatory clearance to launch new formulations into the market, which could negatively impact our future net sales. Our CHCA and CHCI segments are impacted by changes in consumer preferences. If we are unable to adapt to these changes, we may lose market share and our net sales may be negatively impacted. While the market for store brand products has grown in recent years, there can be no assurance that the pace of this growth will continue. Consumer preferences related to health and nutritional concerns may change, which could negatively impact demand for our CHCA and CHCI products or cause us to incur additional costs to change our products or product packaging. • The future growth and stability of U.S. store brand market share will be impacted, in part, by general economic conditions, which can influence consumers to switch to and from store brand products. Our CHCA segment sales could be negatively affected if economic conditions improve and consumers return to purchasing higher-priced brand-name products. Conversely, while store brand products present an 25 Perrigo Company plc - Item 1A Risk Factors alternative to higher-priced branded products, if economic conditions deteriorate, our CHCA segment sales could be negatively impacted if consumers forgo obtaining healthcare or reduce their healthcare spending. • Our CHCI segment's success is dependent on the continued growth in demand for its lifestyle products, which include weight-loss products and various dietary supplements. If demand for these products decreases, our CHCI segment's results of operations would be negatively impacted. • Our CHCA customers may request changes in packaging to meet consumer demands, which could cause us to incur inventory obsolescence charges and redesign costs, which in turn would negatively impact our CHCA segment's results of operations. • Our infant formula product category within our CHCA segment is subject to changing consumer preferences and health and nutrition-related concerns. Our business depends, in part, on consumer preferences and choices, including the number of mothers who choose to use infant formula products rather than breastfeed their babies. To the extent that private, public, and government sources may promote the benefits of breastfeeding over the use of infant formula, there could be a reduced demand for infant formula products. We could also be adversely impacted by an increase in the number of families that are provided with infant formula by the U.S. federal government through the Women, Infants and Children program, as we do not participate in this program. We operate in highly regulated industries, and any inability to timely meet current or future regulatory requirements could have a material adverse effect on our business, financial position, and operating results. We are subject to the regulations of a variety of U.S. and non-U.S. agencies related to the manufacturing, processing, formulation, packaging, labeling, testing, storing, distribution, advertising, and sale of our products as described in detail in Item 1. Business - Government Regulation and Pricing. Government regulation in the markets in which we operate impacts our business, and our future results could be materially adversely affected by changes in such regulations or policies. Below are some of the ways in which government regulation could impact our business and/or financial results: • We must obtain approval from the appropriate regulatory agencies in order to manufacture and sell our products in the regions in which we operate. Obtaining this approval can be time consuming and costly. There can be no assurance that, in the event we submit an application for a marketing authorization to any global regulatory agency, we will obtain the approval to market a product and/or that we will obtain it on a timely basis. Laws unique to the U.S. regulatory framework encourage generic competition by providing eligibility for first generic marketing exclusivity if certain conditions are met. If we are granted generic exclusivity, the exclusivity may be shared with other generic companies, including authorized generics; or it is possible that we may forfeit 180-day exclusivity if we do not obtain regulatory approval or begin marketing the product within the statutory requirements. Finally, if we are not the first to file our ANDA, the FDA may grant 180-day exclusivity to another company, thereby effectively delaying the launch of our product and/or possibly reducing our market share. • Global regulatory agencies regularly inspect our manufacturing facilities and the facilities of our third-party suppliers. The failure of one of our facilities, or a facility of one of our third-party suppliers, to comply with applicable laws and regulations may lead to a breach of representations made to our customers, or to regulatory or government action against us related to the products made in that facility. Such action could include suspension of or delay in regulatory approvals. If the compliance violations are severe, agencies of the government may initiate product seizure, injunction, recall, suspension of production or distribution of our products, loss of certain licenses or other governmental penalties, or civil or criminal prosecution, thereby impacting the reputation of all of our products. • In the U.S., the DSCSA requires development of an electronic pedigree to track and trace each prescription drug at the salable unit level through the distribution system, which will be effective incrementally over a 10- year period beginning on January 1, 2015, for manufacturers, wholesale distributors, and re-packagers, and on July 1, 2015 for dispensers. Similarly, the European Commission passed legislation requiring new product packaging ‘safety features’ to prevent falsification of medicinal products primarily within the 26 Perrigo Company plc - Item 1A Risk Factors prescription medicines sector. The act was adopted February 9, 2016. EU member states (with the exception of Belgium, Italy and Greece), and EEA members Norway, Iceland, Liechtenstein and Switzerland must be in compliance within three years, or by February 9, 2019. Belgium, Italy, and Greece have until February 9, 2025 to comply. Marketing Authorization holders will have three years from the publication date to implement the necessary changes or risk forfeiting their product licenses. Compliance with the new U.S. and EU electronic pedigree requirements may increase our operational expenses and impose significant administrative burdens. • Global regulatory agencies highly scrutinize any product application submitted to switch a product from physician prescribed Rx to unsupervised OTC use by the general public. The expansion of Rx-to-OTC switches is critical to our future growth. Reluctance of regulatory agencies to approve Rx-to-OTC switches in new product categories could impact that growth. • Our infant formula products may be subject to barriers or sanctions imposed by countries or international organizations limiting international trade and dictating the specific content of infant formula products. Governments could enhance regulations on the industry aimed at ensuring the safety and quality of dairy products, including, but not limited to, compulsory batch-by-batch inspection and testing for additional safety and quality issues. Such inspections and testing may increase our operating costs related to infant formula products. • • If we are unable to successfully obtain the necessary quota for controlled substances and List I chemicals, we risk having delayed product launches or failing to meet commercial supply obligations. If we are unable to comply with regulatory requirements for controlled substances and List I chemicals, the DEA, or similar regulatory agency, may take regulatory actions, resulting in temporary or permanent interruption of distribution of our products, withdrawal of our products from the market, or other penalties. In order to commercially distribute our medical device products in the EU, they need to conform with the requirements of applicable EU directives. The method of assessing conformity varies depending on the class of the product, but normally involves a combination of self-assessment by the manufacturer and a third-party assessment by a Notified Body, an organization accredited by a member state, which includes an audit of the manufacturer’s quality system and, for some products, specific product testing. If our products fail to meet the applicable EU directives, then we may not meet our projected growth targets and/ or incur fines and penalties. • Our operations extend to numerous countries outside the U.S. and are subject to the risks inherent in conducting business globally and under the laws, regulations, and customs of various jurisdictions. These risks include compliance with a variety of national and local laws of countries in which we do business, such as restrictions on the import and export of certain intermediates, drugs, and technologies. We must also comply with a variety of U.S. laws related to doing business outside of the U.S., including Office of Foreign Asset Controls; United Nations and EU sanctions; the Iran Threat Reduction and Syria Human Rights Act of 2012; and rules relating to the use of certain “conflict minerals” under Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Further changes in laws, regulations, and practices affecting the pharmaceutical industry and the healthcare system, including imports, exports, manufacturing, quality, cost, pricing, reimbursement, approval, inspection, and delivery of healthcare, may affect our business and operations. • Changes in existing regulations or the adoption of new regulations in the countries in which we operate could impose restrictions or delays on our ability to manufacture, distribute, sell or market our products, may be difficult or expensive for us to comply with, and may adversely affect our revenues, results of operations, or financial condition. 27 Perrigo Company plc - Item 1A Risk Factors Continuing Healthcare reforms and related changes to reimbursement methods in and outside of the United States may have an adverse effect on our financial condition and results of operations. Increasing healthcare expenditures have received considerable public attention in many of the countries in which we operate. In the U.S., government programs such as Medicare and Medicaid, as well as private insurers, have been focused on cost containment. In some markets in the EU and outside the U.S., the government provides healthcare at low direct cost to consumers and regulates pharmaceutical prices or patient reimbursement levels to control costs for the government-sponsored healthcare system. Both private and governmental entities are seeking ways to reduce or contain healthcare costs. Our RX segment in particular could be materially adversely impacted by measures taken by governmental entities or private insurers to restrict patients' access to our products or increase pressure on drug pricing, including denial of price increases, prospective and retrospective price decreases, and increased mandatory discounts or rebates. These actions may drive us and our competitors to decrease prices or may reduce the ability of customers to pay for our products, which could materially negatively impact the RX segment's results of operations. If we fail to comply with the reporting and payment obligations under the Medicaid rebate program or other governmental purchasing and rebate programs, we could be subject to fines or penalties, which could have an adverse effect on our financial condition and results of operations. As described in Item 1. Business - Medicaid Drug Rebate Programs, we have entered into various government drug pricing agreements with the U.S. government. There are inherent risks associated with participating in these programs, including the following: • By their nature, these programs require us to provide discounts and rebates and therefore reduce our net product revenues. Further, because the amounts of these discounts are based on our commercial sales practices and can be adversely affected by both significant discounts and price increases, it is important that we maintain pricing practices that appropriately take into account these government pricing programs. • We are required to report pricing data to CMS, including AMP, on a monthly and quarterly basis and BP and ASP on a quarterly basis. We also are required to report quarterly and annual Non-FAMPs to the VA. If we fail to submit required information on a timely basis, make misrepresentations, or knowingly submit false information to the government as to AMP, ASP, or BP, we may be liable for substantial civil monetary penalties or subject to other enforcement actions, such as under the False Claims Act, and CMS may terminate our Medicaid drug rebate agreement. In that event, U.S. federal payments may not be available under Medicaid or Medicare Part B for our covered outpatient drugs. • Because many of our products may be subject to Medicaid FULs or CMS’s new Medicaid “actual acquisition cost” payment methodology standard, our products may be subject to reimbursement pressures, and in some cases, those pressures may result from practices outside of our control, including how our competitors price their equivalent products. Based on our initial evaluation, we do not believe that the changes have had a material impact on our business. However, states are continuing to evaluate their payment methods, and we cannot predict how the new FUL or state payment methodologies will affect our pharmacy customers or to what extent these customers may seek additional discounts in light of reimbursement changes. We also cannot predict how the sharing of FUL data and retail survey prices may impact competition in the marketplace in the future. • Under the 340B program, if we fail to provide required discounts to covered entities, we may be subject to refund claims or civil money penalties under that program. • If we inadvertently overcharge the government in connection with our FSS contract or TriCare Agreement, whether due to a misstated FCP or otherwise, we would be required to refund the difference. Failure to make necessary disclosures and/or to identify contract overcharges can result in False Claims Act allegations or potential violations of other laws and regulations. Unexpected refunds to the government, and responses to a government investigation or enforcement action, are expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations, and growth prospects. 28 Perrigo Company plc - Item 1A Risk Factors • Our reporting and payment obligations under the Medicaid rebate program and other governmental purchasing and rebate programs are complex and may involve subjective decisions. Our calculations and methodologies are subject to review by the governmental agencies, and it is possible that these reviews could result in challenges to our submissions. If we do not comply with those reporting and payment obligations, we could be subject to civil and/or criminal sanctions, including fines, penalties, and possible exclusion from U.S. federal healthcare programs. Lack of availability, or significant increases in the cost, of raw materials used in manufacturing our products could adversely impact our profit margins and operating results. Affordable high quality raw materials and packaging components are essential to all of our business units due to the nature of the products we manufacture. In addition, maintaining good supply relationships is essential to our ongoing operations. See Item 1. Business - Materials Sourcing for more information. • We maintain several single-source supplier relationships, either because alternative sources are not available or because the relationship is advantageous due to regulatory, performance, quality, support, or price considerations. Unavailability or delivery delays of single-source components or products could adversely affect our ability to ship the related product in a timely manner. The effect of unavailability or delivery delays would be more severe if associated with our higher-volume or more profitable products. Even where alternative sources of supply are available, qualifying the alternate suppliers and establishing reliable supplies could cost more or result in delays and a loss of net sales. Additionally, global regulatory requirements for obtaining product approvals could substantially lengthen the approval of an alternate material source. As a result, the loss of a single-source supplier could have a material adverse effect on our results of operations. • The rapid increase in cost of many raw materials from inflationary forces, such as increased energy costs, and our ability or inability to pass on these increases to our customers could have a negative material impact on our financial results. • Our infant formula products require certain key raw ingredients that are derived from raw milk, such as skim milk powder, whey protein powder, and lactose. Our supply of milk-based ingredients may be limited by the ability of individual dairy farmers and cooperatives to provide raw milk in the amount and quality we deem necessary. Raw milk production is influenced by factors beyond our control including seasonal and environmental factors, governmental agricultural and environmental policy, and global demand. We cannot guarantee that there will be sufficient supplies of these key ingredients necessary to produce infant formula. • Our products, and the raw materials used to make the products mentioned above, generally have limited shelf lives. Our inventory levels are based, in part, on expectations regarding future sales. We may experience build-ups in inventory if sales slow. Any significant shortfall in sales may result in higher inventory levels of raw materials and finished products, thereby increasing the risk of inventory spoilage and corresponding inventory write-downs and write-offs. Cargo thefts and/or diversions, and economically or maliciously motivated product tampering on store shelves may occur, causing unexpected shortages and harm to our reputation, which may have a material impact on our operations. • We rely on third parties to source many of our raw materials, as well as to manufacture sterile, injectable products that we distribute. We maintain a strict program of verification and product testing throughout the ingredient sourcing and manufacturing process to identify potential counterfeit ingredients, adulterants, and toxic substances. Nevertheless, discovery of previously unknown problems with the raw materials or product manufacturing processes, or new data suggesting an unacceptable safety risk associated therewith, could result in a voluntary or mandatory withdrawal of the contaminated product from the marketplace, either temporarily or permanently. Any future recall or removal would result in additional costs and lost revenue, harm our reputation, and may give rise to product liability litigation. • Changes in regulation could impact the supply of the API and certain other raw materials used in our products. For example, the EU recently promulgated new standards requiring all API imported into the EU be certified as complying with GMP established by the EU. The regulations placed the certification 29 Perrigo Company plc - Item 1A Risk Factors requirement on the regulatory bodies of the exporting countries, which led to an API supply shortage in Europe as certain governments were not willing or able to comply with the regulation in a timely fashion, or at all. A shortage in API or other raw ingredients could cause us to have to cease manufacture of certain products, or to incur costs and delays to qualify other suppliers to substitute for those API manufacturers are unable to export. This could have a material adverse effect on our business, results of operations, financial condition, and cash flow. A disruption at any of our main manufacturing facilities could materially and adversely affect our business, financial position, and results of operations. Our manufacturing operations are concentrated in a few locations. See Item 1. Business - Manufacturing and Distribution for more information on our significant operations. A significant disruption at one or more of these facilities, whether it be due to fire, natural disaster, power loss, intentional acts of vandalism, war, terrorism, insufficient quality, or pandemic could materially and adversely affect our business. Additionally, regulatory authorities routinely inspect all of our manufacturing facilities for cGMP compliance. While our manufacturing sites are cGMP compliant, if a regulatory authority were to identify serious adverse findings not corrected upon follow up inspections, we may be required to issue product recalls, shutdown manufacturing facilities, and take other remedial actions. If any manufacturing facility were forced to cease or limit production, our business could be adversely affected. Any breach, disruption or misuse of our information systems, cyber security efforts or personal data could have a material adverse effect on our business. We are increasingly dependent upon information technology systems to operate our business. Our systems, information, and operations, as well as our independent vendor relationships (where they support information technology and manufacturing infrastructure), are highly complex. These systems may contain confidential information (including trade secrets or other intellectual property or proprietary business information). The size and complexity of these systems makes them potentially vulnerable to disruption or damage from security breaches, hacking, data theft, denial of service attacks, human error, sabotage, industrial espionage, and computer viruses. Such events may be difficult to detect, and once detected, their impact may be difficult to assess. While we continue to employ resources to monitor our systems and protect our infrastructure, these measures may prove insufficient depending upon the attack or threat posed. We are subject to numerous laws and regulations designed to protect personal data, such as the national laws implementing the European Union Directive on Data Protection (which will be replaced by the EU GDPR from May 2018 onward). The EU GDPR will introduce more stringent data protection requirements in the EU, as well as substantial fines for breaches of the data protection rules. The EU GDPR will increase our responsibility and liability in relation to personal data that we process, and we may be required to put in place additional mechanisms to ensure compliance with the new EU data protection rules. These risks include: • Breaches or disruptions could impair our ability to develop, meet regulatory approval efforts, produce, and/ or ship products, take and fulfill orders, and/or collect and make payments on a timely basis; • Any system issue, whether as a result of an intentional breach or a natural disaster, could damage our reputation and cause us to lose customers, experience lower sales volume, and incur significant liabilities; • We could incur significant expense by ensuring compliance with any required disclosures mandated by the numerous global privacy and security laws and regulations; and • Any interruption, security breach, or loss, misappropriation, or unauthorized access, use or disclosure of confidential information, could result in financial, legal, business, and reputational harm to us and could have a material adverse effect on our business, financial condition, and results of operations. 30 Perrigo Company plc - Item 1A Risk Factors Because our business depends upon certain customers for a significant portion of our sales, our business would be adversely affected by a disruption of our relationship with these customers or any material adverse change in these customers' businesses. Sales to our largest customer, Walmart, comprised approximately 13% of our net sales for the year ended December 31, 2017. While no other customer individually comprised more than 10% of net sales, we do have other significant customers. If our relationship with Walmart or any of our other significant customers, including the terms of doing business with the customers, changes significantly, it could have a material adverse impact on us (refer to Item 1. Business - Significant Customers). Many of our customers, which include chain drug stores, wholesalers, distributors, hospital systems, and group purchasing organizations, continue to merge or consolidate. Such consolidation has provided, and may continue to provide, customers with additional purchasing leverage, and consequently may increase the pricing pressures we face. The emergence of large buying groups representing independent retail pharmacies enable those groups to extract price discounts on our products. In addition, a number of our customers have instituted sourcing programs limiting the number of suppliers of generic pharmaceutical products carried by that customer. These developments have resulted in heightened pricing pressure on our products, as well as competition among generic drug producers for business from a smaller and more selective customer base. Additionally, if we are unable to maintain adequately high levels of customer service over time, customers may choose to assess penalties, obtain alternate sources for products, and/or end their relationships with us. Although we have divested our rights to the Tysabri® royalty stream, we are entitled to additional milestone payments if certain specified thresholds are met, and any negative developments related to Tysabri® could have a material adverse effect on our receipt of those payments. We occasionally enter into arrangements that entitle us to potential royalties from third parties. Our most significant royalty has been the Tysabri® royalty stream which we received quarterly from Biogen. During the year ended December 31, 2016, $84.4 million of cash was earned, which was received during the year ended December 31, 2017. On March 27, 2017, we divested our rights to the Tysabri® royalty stream to Royalty Pharma for $2.2 billion in cash at closing and up to $250.0 million and $400.0 million in milestone payments if global net sales of Tysabri® meet specific thresholds in 2018 and 2020, respectively. Our receipt of these milestone payments may be negatively impacted if the royalty streams decrease and are insufficient to meet the specified thresholds. Given the fact these milestone payments are recorded at fair value, if it is determined that Tysabri® global sales levels do not meet specific thresholds, we would recognize a material charge in the Consolidated Statement of Operations. Factors that may have an adverse effect on the Tysabri® royalty stream include: • Companies working to develop new therapies or alternative formulations of products for multiple sclerosis that, if successfully developed, would compete with, or could gain greater acceptance than, Tysabri® and damage it’s market share. In February 2016, a competitor's pipeline product, Ocrevus®, received breakthrough therapy designation from the FDA, this product was launched in 2017. The product is expected to compete with Tysabri® and have a significant negative impact on the Tysabri® royalty stream; • Biogen is the owner of the patents on Tysabri®. The loss of protection of these patents, such as a patent invalidation, could adversely affect the royalty stream from Tysabri®. In addition, once the Tysabri® patents expire, other generic companies may introduce products similar to Tysabri® that could adversely affect the royalty stream; • Foreign currency movement, which could have a negative impact on Biogen's Tysabri® sales, thereby reducing the royalties; • Any negative developments relating to Tysabri®, such as safety, efficacy, or reimbursement issues, could reduce demand for Tysabri®; and • Adverse regulatory or legislative developments could limit or prohibit the sale of Tysabri®, such as restrictions on the use of Tysabri® or safety-related label changes, including enhanced risk management 31 Perrigo Company plc - Item 1A Risk Factors programs, which may significantly reduce expected royalty revenue and require significant expense and management time to address the associated legal and regulatory issues. Additionally, Tysabri® sales growth cannot be assured given the significant restrictions on its use and the significant safety warnings on the label, including the risk of developing Progressive Multifocal Leukoencephalopathy ("PML"), a serious brain infection. The risk of developing PML may increase with prior immunosuppressant use, longer treatment duration, or the presence of certain antibodies. Increased incidence of PML could limit sales growth, prompt regulatory review, require significant changes to the label, or result in market withdrawal. In addition, the result of ongoing or future clinical trials involving Tysabri® or other adverse events reported in association with the use of Tysabri® may have an adverse impact on prescribing behavior and reduce sales of Tysabri®. Furthermore, there can be no assurance that Royalty Pharma will pay either or both of the milestone payments even if the specified thresholds are met. We are dependent on the services of certain key members of management. Our inability to successfully manage transition, or the failure to attract and retain other key members of management, may have a material adverse impact on our results of operations. We are dependent on the services of certain key employees, and our future success will depend in large part upon our ability to attract and retain highly skilled employees. Key functions for us include executive managers, operational managers, R&D scientists, information technology specialists, financial and legal specialists, regulatory professionals, quality compliance specialists, and sales/marketing personnel. If we are unable to attract or retain key qualified employees, our future operating results may be adversely impacted. Management transition creates uncertainties, and any difficulties we experience in managing such transitions may negatively impact our business. Recently, we have experienced changes in our executive leadership. In June 2017, we announced the forthcoming retirement of John T. Hendrickson as our Chief Executive Officer. On January 8, 2018, we announced the appointment of Uwe Roehrhoff as President and Chief Executive Officer and member of our Board. Mr. Hendrickson will continue to serve in an advisory role until March 15, 2018. In addition, in February 2017, we announced the resignation of Judy L. Brown as our Executive Vice President, Business Operations and Chief Financial Officer, effective February 27, 2017. Ronald L. Winowiecki, who had been with the Company in various treasury and senior finance roles since October 2008, most recently as our Senior Vice President of Business Finance, served as acting Chief Financial Officer from February 27, 2017 until his appointment as Chief Financial Officer on February 20, 2018. Changes in executive management create uncertainty. Moreover, changes in our company as a result of management transition could have a disruptive impact on our ability to implement, or result in changes to, our strategy and could negatively impact our business, financial condition and results of operations. Unfavorable publicity or consumer perception of the safety, quality, and efficacy of our products could have a material adverse impact on our business. We are dependent upon consumers' perception of the safety, quality, and efficacy of our products, and may be affected by changing consumer preferences. Negative consumer perception may arise from media reports, product liability claims, regulatory investigations, or recalls, regardless of whether they involve us or our products. The mere publication of information asserting defects in products or ingredients, or concerns about our products or the materials used in our products, could discourage consumers from buying our products, regardless of whether such information is scientifically supported. • Our products involve risks such as product contamination, spoilage, mislabeling, and tampering that could require us to recall one or more of our products. Serious product quality concerns could also result in governmental actions against us that, among other things, could result in the suspension of production or distribution of our products, product seizures, loss of certain licenses, delays in the issuance of governmental approvals for new products, or other governmental penalties, all of which could be detrimental to our reputation and reduce demand for our products. 32 Perrigo Company plc - Item 1A Risk Factors • We cannot guarantee that counterfeiting, imitation or other tampering with our products will not occur or that we will be able to detect and resolve it. Any counterfeiting or contamination of any products could negatively impact our reputation and sales, particularly if counterfeit or imitation products cause death or injury to consumers. • Many of the brands we acquired from Omega have European recognition. This recognition is the result of the large investments Omega has made in its products over many years. The quality and safety of the products are critical to our business. If we are unable to effectively manage real or perceived issues, including concerns about safety, quality, efficacy, or similar matters, sentiments toward us and our products could be negatively impacted. • Our CHCI segment's financial success is dependent on the success of its brands, and the success of these brands can suffer if marketing plans or product initiatives do not have the desired impact on a brand’s image or its ability to attract consumers and the performance of the segment may be negatively impacted if spending on such plans and initiatives does not generate the returns we anticipate. In addition, given the association of individual products within the commercial network of our CHCI segment, an issue with one of our products could negatively affect the reputation of other products, thereby potentially hurting our financial results. • Powdered infant formula products are not sterile. All of our infant formula products must be prepared and maintained according to label instruction to retain their flavor and nutritional value and avoid contamination or deterioration. Depending on the product, a risk of contamination or deterioration may exist at each stage of the production cycle, including the purchase and delivery of raw materials, the processing and packaging of food products, and the use and handling by consumers, hospital personnel, and healthcare professionals. In the event that certain of our infant formula products are found or alleged to have suffered contamination or deterioration, whether or not under our control, our reputation and our infant formula product category sales could be materially adversely affected. Increasing use of social media could give rise to liability, breaches of data security, or reputation damage. The Company and our employees increasingly utilize social media as a means of internal and external communication. • To the extent that we seek to use social media tools as a means to communicate about our products and/or business, there are uncertainties as to the rules that apply to such communications, or as to the interpretations that authorities will apply to the rules that exist. As a result, despite our efforts to monitor evolving social media communication guidelines and comply with applicable rules, there is risk that our use of social media for such purposes may cause us to be found in violation of them. A violation of such guidelines may damage our reputation as well as cause potential lawsuits and adversely affect our operating activities. • Our employees may knowingly or inadvertently make use of social media tools in ways that may not be aligned with our social media strategy, may give rise to liability, or could lead to the loss of trade secrets or other intellectual property, or public exposure of personal information (including sensitive personal information) of our employees, clinical trial patients, customers, and others. • Negative posts or comments about us, store brands or generic pharmaceuticals, or our products in social media could seriously damage our reputation and could adversely affect the price of our securities. In addition, negative posts or comments about our products could result in increased pharmacovigilance reporting requirements, which may give rise to liability if we fail to fully comply with such requirements. 33 Perrigo Company plc - Item 1A Risk Factors Our quarterly results are impacted by a number of factors, some of which are beyond the control of our management, that may result in significant quarter-to-quarter fluctuations in operating results. Some of the factors that may impact our quarterly results include the severity, length and timing of the cough/cold/flu and allergy seasons, the flea and tick season, the timing of new product approvals and introductions by us and our competitors, price competition, changes in the regulatory environment, changes in accounting pronouncements, changes in the levels of inventories maintained by our customers, and the timing of retailer promotional programs. These and other factors may result in significant variations in our operating results from quarter to quarter. We may not be able to sustain or improve operating results in our business segments. • We have experienced a reduction in pricing expectations during 2017 in comparison to historical patterns in our U.S. businesses, in particular in our RX segment, due to competitive pressures in the sector. The reduced pricing is attributable to a variety of factors including increased focus from customers to capture supply chain productivity savings, competition in specific product categories, the loss of exclusivity on certain products, the recent increase in the speed and number of approvals from the FDA, and consolidation of certain customers in the RX segment. We expect this pricing environment to continue to impact the Company for the foreseeable future. • The CHCI segment has been positively impacted by market dynamics in countries such as the Nordics, Italy, and Portugal offset by softness in certain brand categories in France and Germany, as well as by unfavorable foreign currency impacts primarily in the U.K. related to Brexit. In addition, the segment had been impacted in Belgium due to cancellations of unprofitable distribution agreements. The CHCI segment has restructured its approach to addressing these markets including: (1) the implementation of a brand prioritization strategy to address these market dynamics, with an objective to balance the cost of advertising and promotional investments with expected contributions from category sales, and (2) restructured its sales force in each of these markets to more effectively serve customers. The combination of these actions is expected to improve the segment's focus on higher value OTC products, reduce selling costs and improve operating margins in the segment. • We continue to experience a reduction in pricing expectations within our CHCA segment, primarily in the cough/cold, animal health, and analgesics categories due to various factors, including focus from customers to capture supply chain productivity savings and competition in specific product categories. We expect this pricing environment to continue to impact our CHCA segment for the foreseeable future. There can be no assurance that we will not continue to experience challenges related to our segments, and these challenges could have a material impact on our business, cash flows, and results of operations or result in impairment charges, and the market value of our ordinary shares and/or debt securities may decline. We may not realize the benefits of business acquisitions and divestitures we enter into, which could have a material adverse effect on our operating results. In the normal course of business, we engage in discussions relating to possible acquisitions and divestitures. These transactions are accompanied by a number of risks. Many of these risks are beyond our control, and any one of them could result in increased cost, decreased net sales and diversion of management’s time and energy, any or all of which could materially impact our business, financial condition, and results of operations. Acquisitions One of our strategies is inorganic growth through the acquisition of products and companies that we expect will benefit the Company. This strategy comes with a number of financial, managerial, and operational risks. We may not realize the benefits of an acquisition because of integration and other challenges, including, but not limited to the following: • Difficulty involved with managing the expanded operations of the respective parties, as well as identifying the extent of all weaknesses, risks, and contingent and other liabilities; 34 Perrigo Company plc - Item 1A Risk Factors • Uncertainties involved in assessing the value, strengths, and potential profitability of the respective parties, as well as identifying the extent of all weaknesses, risks, and contingent and other liabilities of acquisition targets; • Unanticipated changes in the business, industry, market or general economic conditions different from the assumptions underlying our rationale for pursuing the transaction; • Difficulties due to a lack of, or limited experience in, any new product or geographic markets we enter; • Inability to achieve identified operating and financial synergies, or return on investment, from an acquisition in the amounts or on the time frame anticipated; • Substantial demands on our management, operational resources, technology, and financial and internal control systems, which could lead to dissatisfaction and potential loss of key customers, management, or employees; • Integration activities that may detract attention from our day-to-day business, and substantial costs associated with the transaction process or other material adverse effects as a result of these integration efforts; and • Difficulties, restrictions or increased costs associated with raising future capital in connection with an acquisition may impact our liquidity, credit ratings and financial position, thereby making it more difficult, restrictive or expensive to raise future capital. In addition, the issuance of equity to pay a portion of the purchase price for an acquisition would dilute our existing shareholders. Divestitures We may evaluate potential divestiture opportunities with respect to portions of our business (including specific assets or categories of assets) from time to time, and may proceed with a divestiture opportunity if and when we believe it is consistent with our business strategy and initiatives. Any future divestitures could expose us to significant risk, including without limitation: • Our ability to effectively transfer liabilities, contracts, facilities and personnel to any purchaser; • Fees for legal and transaction-related services; • Diversion of management resources; and • Loss of key personnel and reduction in revenue. If we do not realize the expected strategic, economic or other benefits of any divestiture transaction, it could adversely affect our financial condition and results of operations. Our business could be negatively affected by the performance of our collaboration partners and suppliers. We have entered into strategic alliances with partners and suppliers to develop, manufacture, market and/or distribute certain products, or components of our products in various markets. We commit substantial effort, funds and other resources to these various collaborations. There is a risk that our investments in these collaborative arrangements will not generate financial returns. While we believe our relationships with our partners and suppliers generally are successful, disputes, conflicting priorities or regulatory or legal intervention could be a source of delay or uncertainty as to the expected benefit of the collaboration (refer to Item 8. Note 17 for additional detail on our collaborative agreements and other contractual arrangements). A failure or inability of our partners or suppliers to fulfill their collaboration obligations, or the occurrence of any of the risks above, could have an adverse effect on our business, financial condition and results of operations. We have acquired significant assets that could become impaired or subject us to losses and may result in an adverse impact on our results of operations. We have recorded significant intangible assets and goodwill on our balance sheet as a result of previous acquisitions, which could become impaired and lead to material charges in the future. As of the year ended December 31, 2017, we recorded definite-lived intangible asset impairment charges of $19.7 million related to developed product technology/formulation and product rights, and distribution and license 35 Perrigo Company plc - Item 1A Risk Factors agreements primarily in our RX segment and $12.7 million of impairment charge related to certain IPR&D assets primarily in our RX segment. As of the year ended December 31, 2016, we recorded the following impairments: • Goodwill impairment charges of $1.1 billion related to our Specialty Sciences, Branded Consumer Healthcare-Rest of World ("BCH-ROW"), BCH-Belgium, and Animal Health reporting units. • Indefinite-lived and definite-lived intangible asset impairment charges of $1.5 billion related to: Trademarks, trade names and brands, developed product technology/formulation and product rights, distribution and license agreements, and supply agreements. We perform an impairment analysis on intangible assets subject to amortization when there is an indication that the carrying amount of any individual asset may not be recoverable. Any significant change in market conditions, estimates or judgments used to determine expected future cash flows that indicates a reduction in carrying value may give rise to impairment in the period that the change becomes known. As of December 31, 2017, the net book value of our intangible assets and goodwill were $3.4 billion and $4.2 billion, respectively. See Item 8. Note 3 for more information on the above impairment charges. There can be no assurance that our strategic initiatives will achieve their intended effects. We are in the process of implementing certain initiatives designed to increase operational efficiency and improve our return on invested capital by globalizing our supply chain through global shared service arrangements, streamlining our organizational structure, making key executive employee changes, performing a strategic portfolio review, and disposing of certain assets. We believe these initiatives will enhance our net sales, operating margins, and earnings; however, there can be no assurance that these initiatives will produce the anticipated benefits. Any delay or failure to achieve the anticipated benefits could have a material adverse effect on our projected results. We identified material weaknesses in our internal controls over financial reporting; failure to remediate the material weakness could negatively impact our business and the price of our ordinary shares. In connection with our review of certain material misstatements related to the characterization of the Tysabri® royalty stream, income taxes and the evaluation of long-lived assets in our animal health reporting unit for impairment testing, in each case contained in certain of our historical financial statements and identified as part of our December 31, 2016 year end, we concluded that there were material weaknesses in our internal control over financial reporting that contributed to those misstatements. The material weaknesses over the income tax process that was identified during our fiscal year ended December 31, 2016 was not remediated during our fiscal year ended December 31, 2017, and we determined that we did not design or maintain effective controls over our income tax accounting process. As a result of the material weaknesses, we concluded that we did not maintain, in all material respects, effective internal control over financial reporting as of December 31, 2016, April 1, 2017, July 1, 2017, September 30, 2017 or December 31, 2017 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The failure to maintain effective control over financial reporting in turn resulted in material deficiencies in our disclosure controls and procedures. We continue to identify and implement, actions to improve the effectiveness of our internal control over financial reporting and disclosure controls and procedures, but there can be no assurance that such remediation efforts will be successful. We have also incurred and may continue to incur substantial accounting, legal, consulting, and other costs in connection with remediating the material weaknesses. Failure to remediate the material weaknesses could have a negative impact on our business and the market for our ordinary shares. For more information on our material weaknesses and the status of our remediation efforts, see Item 9A - Controls and Procedures, which includes Management's Report on Internal Control over Financial Reporting. 36 Perrigo Company plc - Item 1A Risk Factors Global Risks Our business, financial condition, and results of operations are subject to risks arising from the international scope of our operations. We manufacture, source raw materials, and sell our products in a number of countries. The percentage of our business outside the U.S. has been increasing. We are subject to risks associated with international manufacturing and sales, including: • Unexpected changes in regulatory requirements; • Problems related to markets with different cultural biases or political systems; • Possible difficulties in enforcing agreements; • • Difficulties obtaining export or import licenses; • Changes to U.S. and foreign trade policies, including the enactment of tariffs on goods imported into the Longer payment cycles and shipping lead-times; U.S., including but not limited to, goods imported from Mexico; and Imposition of withholding or other taxes. • Additionally, we are subject to periodic reviews and audits by governmental authorities responsible for administering import/export regulations. To the extent that we are unable to successfully defend against an audit or review, we may be required to pay assessments, penalties, and increased duties. Certain of our facilities operate in a special purpose sub-zone established by the U.S. Department of Commerce Foreign Trade Zone Board, which allows us certain tax advantages on products and raw materials shipped through these facilities. If the Foreign Trade Zone Board were to revoke the sub-zone designation or limit our use, we could be subject to increased duties. Although we believe that we conduct our business in compliance with applicable anti-corruption, anti-bribery and economic sanctions or other anti-corruption laws, if we are found to not be in compliance with such laws or other anti-corruption laws, we could be subject to governmental investigations, legal or regulatory proceedings, substantial fines, and/or other legal or equitable penalties. This risk increases in locations outside of the U.S., particularly in locations that have not previously had to comply with the FCPA, U.K. Bribery Act, and similar laws. We operate in jurisdictions that could be affected by economic and political instability, which could have a material adverse effect on our business. Our operations and supply partners could be affected by economic or political instability, embargoes, military hostilities, unstable governments and legal systems, and inter-governmental disputes. We have significant operations in Israel, which has experienced varying degrees of hostility in recent years. Doing business in Israel and certain other regions involves the following risks: • Certain countries and international organizations have refused to do business with companies with Israeli operations. We are also precluded from marketing our products to certain countries due to U.S. and Israeli regulatory restrictions. International economic sanctions and boycotts of our products could negatively impact our sales and ability to export our products. • Our facilities in Israel are within a conflict zone. If terrorist acts or military actions were to result in substantial damage to our facilities, our business activities would be disrupted since, with respect to most products, we would need to obtain prior regulatory agency approval for a change in manufacturing site. In addition, our insurance may not adequately compensate us for losses that may occur, and any losses or damages incurred by us could have a material adverse effect on our business. 37 Perrigo Company plc - Item 1A Risk Factors • The U.S. Department of State and other governments have at times issued advisories regarding travel to certain countries in which we do business. As a result, regulatory agencies have at various times curtailed or prohibited their inspectors from traveling to inspect facilities. If these inspectors are unable to inspect our facilities, the regulatory agencies could withhold approval for new products intended to be produced at those facilities. • Our international operations may be subject to interruption due to travel restrictions, war, terrorist acts, and other armed conflicts. Also, further threats of armed hostilities in certain countries could limit or disrupt markets and our operations, including disruptions resulting from the cancellation of contracts or the loss of assets. These events could have a material adverse effect on our international business operations. • The UK held a referendum on June 23, 2016 on its membership in the EU. A majority of UK voters voted to exit the EU (“Brexit”). The UK is scheduled to leave the EU on March 29, 2019, and negotiations are taking place to determine the future terms of the UK’s relationship with the EU, including the terms of withdrawal, the terms of future trading and relations and any potential transition periods. Brexit has created significant instability and volatility in the global financial markets, has led to significant weakening of the British pound compared to the U.S. dollar and other currencies, and could adversely affect European or worldwide economic or market conditions. Although it is unknown what the future trading terms with the EU will be, they may impair the ability of our operations in the EU to transact business in the future in the UK, and similarly the ability of our UK operations to transact business in the future in the EU. Specifically, it is possible that there will be greater restrictions on imports and exports between the UK and EU countries, increased restrictions on freedom of movement for employees, and increased regulatory complexities. In addition, Brexit could lead to legal uncertainty and potentially divergent national laws and regulations as the UK determines which EU laws to replace or replicate. Further, among other things, Brexit could reduce consumer spending in the UK and the EU, which could result in decreased demand for our products. Any of these effects of Brexit, and others we cannot anticipate, could adversely affect our business, business opportunities, operations, and financial results. • While the challenging global economic environment has not had a material impact on our liquidity or capital resources, there can be no assurance that possible future changes in global financial markets and global economic conditions will not affect our liquidity or capital resources, impact our ability to obtain financing, or decrease the value of our assets. • The challenging economic conditions have also impacted the movements in exchange rates, which have experienced significant recent volatility. Uncertainty regarding the future growth rates between countries, the influence of central bank actions, and the changing political environment globally may contribute to continued high levels of exchange rate volatility, which could have an adverse impact on our results. • Our customers could be adversely impacted if economic conditions worsen. Our CHCA segment does not advertise its products like national brand companies and thus is largely dependent on retailer promotional activities to drive sales volume and increase market share. If our customers do not have the ability to invest in store brand promotional activities, our sales may suffer. Additionally, while we actively review the credit worthiness of our customers and suppliers, we cannot fully predict to what extent they may be negatively impacted by slowing economic growth. The international scope of our business exposes us to risks associated with foreign exchange rates. We report our financial results in U.S. dollars. However, a significant portion of our net sales, assets, indebtedness and other liabilities, and costs are denominated in foreign currencies. These currencies include among others the euro, Indian rupee, British pound, Canadian dollar, Israeli shekel, Australian dollar, and Mexican peso. The addition of Omega, a euro-denominated business, that represents a significant portion of our net sales and earnings, and a substantial portion of our net assets, has significantly increased our exposure to changes in the euro/U.S. dollar exchange rate. Approximately 34% of Omega’s sales are in other foreign currencies, with the majority of the product costs for these markets denominated in euros. In addition, several emerging market economies are particularly vulnerable to the impact of rising interest rates, inflationary pressures, weaker oil and other commodity prices, and large external deficits. While some of 38 Perrigo Company plc - Item 1A Risk Factors these jurisdictions are showing signs of stabilization or recovery, others continue to experience levels of stress and volatility. Risks in one country can limit our opportunities for portfolio growth and negatively affect our operations in another country or countries. As a result, any such unfavorable conditions or developments could have an adverse impact on our operations. Our results of operations and, in some cases, cash flows, have in the past been, and may in the future be, adversely affected by movements in exchange rates. In addition, we may also be exposed to credit risks in some of those markets. We may implement currency hedges or take other actions intended to reduce our exposure to changes in foreign currency exchange rates. If we are not successful in mitigating the effects of changes in exchange rates on our business, any such changes could materially impact our results. Risks Related to Litigation and Insurance We are or may become involved in lawsuits and may experience unfavorable outcomes of such proceedings. We may become involved in lawsuits arising from a wide variety of commercial, manufacturing, development, marketing, sales and other business-related matters, including, but not limited to, competitive issues, pricing, contract issues, intellectual property matters, false advertising, unfair competition, taxation matters, workers' compensation, product quality/recall, environmental remediation, securities law, disclosure, and regulatory issues. Litigation is unpredictable and can be costly. We intend to vigorously defend against any lawsuits, however, we cannot predict how the cases will be resolved. Adverse results in the cases could result in substantial monetary judgments. No assurance can be made that litigation will not have a material adverse effect on our financial position or results of operations in the future (refer to Item 8. Note 16 for more information on specific ongoing litigation). • We may be subject to liability if our products violate applicable laws or regulations in the jurisdictions where our products are distributed. The successful assertion of product liability or other product-related claims against us could result in potentially significant monetary damages, and we could incur substantial legal expenses. Even if a product liability or consumer fraud claim is unsuccessful, not merited, or not fully pursued, we may still incur substantial legal expenses defending against such a claim, and our reputation may suffer. • We may face environmental exposures including, for example, those relating to discharges from and materials handled as part of our operations, the remediation of soil and groundwater contaminated by hazardous substances or wastes, and the health and safety of our employees. While we do not have any material remediation liabilities currently outstanding, we may in the future face liability for the costs of investigation, removal or remediation of certain hazardous substances or petroleum products on, under or in our currently or formerly owned property, or from a third-party disposal facility that we may have used, without regard to whether we knew of, or caused, the presence of the contaminants. The actual or alleged presence of these substances, or the failure to remediate them, could have adverse effects, including, for example, substantial investigative or remedial obligations and limitations on our ability to sell or rent affected property or to borrow funds using affected property as collateral. There can be no assurance that environmental liabilities and costs will not have a material adverse effect on us. See Item 1. Business - Information Applicable to All Reportable Segments - Environmental for more information. • Our CHCI segment regularly makes advertising claims regarding the effectiveness of its products, which we are responsible for defending. An unsuccessful defense of product-related claims could result in potentially significant monetary damages and substantial legal expenses. Even if a claim is unsuccessful, not merited, or not fully pursued, we may still incur substantial legal expenses defending against such a claim, and our reputation could suffer. • Additionally, we may be the target of claims asserting violations of securities fraud and derivative actions, or other litigation proceedings in the future. 39 Perrigo Company plc - Item 1A Risk Factors Increased scrutiny on pricing practices and competition in the pharmaceutical industry, including antitrust enforcement activity by government agencies and class action litigation, may have an adverse impact on our business and results of operations. There has been increased scrutiny regarding sales, marketing, and pricing practices in the pharmaceutical industry from both government agencies and the media, including allegations of “price gouging” and/or collusion. This includes recent U.S. Congressional inquiries and hearings in connection with the investigation of specific price increases by several pharmaceutical companies, proposed and enacted legislation seeking greater transparency in drug pricing, and criminal investigations regarding drug pricing. U.S. federal and state prosecutors have issued subpoenas to a number of pharmaceutical companies seeking information about their drug pricing practices, and several class action lawsuits have been filed that allege price-fixing with respect to various pharmaceutical products. In December 2016, the Antitrust Division of the U.S. Department of Justice (the “Antitrust Division”) filed criminal charges against two former executives from a competitor of the Company for their roles in conspiracies to fix prices, rig bids and allocate customers for certain generic drugs. On May 2, 2017, we disclosed that search warrants were executed at a number of Perrigo facilities and other locations in connection with the Antitrust Division’s ongoing investigation related to drug pricing in the pharmaceutical industry. Although no charges have been brought to date against Perrigo or any of our current employees (or, to the best of our knowledge, former employees), we take the investigation very seriously. If criminal antitrust charges are filed involving Perrigo, we would incur substantial litigation and other costs, and could face substantial monetary penalties, injunctive relief, negative publicity and damage to our reputation. Regardless of the ultimate outcome, responding to those charges would divert management’s time and attention and could impair our operations. Further, we cannot predict whether legislative or regulatory changes may result from the ongoing public scrutiny of our industry, what the nature of any such changes might be, or what impact they may have on Perrigo. Any of these developments could have a material adverse impact on our business, results of operations, and reputation. We are cooperating with the government’s investigation and are committed to operating our business in compliance with all applicable laws and regulations and the highest standards of ethical conduct. We do not condone, and will not countenance, any violation of these standards by our employees, agents, and business partners. Publishing earnings guidance subjects us to risks, including increased stock volatility that could lead to potential lawsuits by investors. Because we publish earnings guidance, we are subject to a number of risks. Actual results may vary from the guidance we provide investors from time to time, such that our stock price may decline following, among other things, any earnings release or guidance that does not meet market expectations. It has become increasingly commonplace for investors to file lawsuits against companies following a rapid decrease in market capitalization. We have been in the past, and may be in the future, named in these types of lawsuits. These types of lawsuits can be costly and divert management attention and other resources away from our business, regardless of their merits, and could result in adverse settlements or judgments, which could have a material impact on the Company. Third-party patents and other intellectual property rights may limit our ability to bring new products to market and may subject us to potential legal liability, causing us to incur significant costs. The manufacture, use and sale of new products that are the subject of conflicting patent rights have been the subject of substantial litigation in the pharmaceutical industry. 40 Perrigo Company plc - Item 1A Risk Factors • As a manufacturer of generic pharmaceutical products, the ability of our CHCA and RX segments to bring new products to market is often limited by third-party patents or proprietary rights and regulatory exclusivity periods awarded on products. Launching new products prior to resolution of intellectual property issues may result in us incurring legal liability if the related litigation is later resolved against us. The cost and time for us to develop prescription and Rx-to-OTC switch products is significantly greater than the rest of the new products that we introduce. Any failure to bring new products to market in a timely manner could cause us to lose market share, and our operating results could suffer. • We could have to defend against charges that we violated patents or proprietary rights of third parties. This could require us to incur substantial expense and could divert significant effort of our technical and management personnel. If we are found to have infringed on the rights of others, we could lose our right to develop or manufacture some products or could be required to pay monetary damages or royalties to license proprietary rights from third parties. Additionally, if we choose to settle a dispute through licensing or similar arrangements, the costs associated with these arrangements may be substantial and could include ongoing royalties. An adverse determination in a judicial or administrative proceeding or failure to obtain necessary licenses could prevent us from manufacturing and selling a number of our products. • At times, our CHCA or RX segments may seek approval to market drug products before the expiration of patents for those products, based upon our belief that such patents are invalid, unenforceable or would not be infringed by our products. In these cases we may face significant patent litigation. Depending upon a complex analysis of a variety of legal and commercial factors, we may, in certain circumstances, elect to market a generic pharmaceutical product while litigation is pending, before any court decision, or while an appeal of a lower court decision is pending, known as an "at risk" launch. The risk involved in an "at risk" launch can be substantial because, if a patent holder ultimately prevails, the remedies available to the patent holder may include, among other things, damages measured by the profits lost by the holder, which are often significantly higher than the profits we make from selling the generic version of the product. By electing to proceed in this manner, we could face substantial damages if we receive an adverse final court decision. In the case where a patent holder is able to prove that our infringement was "willful" or "exceptional," under applicable law, the patent holder may be awarded up to three times the amount of its actual damages or we may be required to pay attorneys’ fees. The success of certain of our products depends on the effectiveness of measures we take to protect our intellectual property rights and patents. If we fail to adequately protect our intellectual property, competitors may manufacture and market similar products. • We have been issued patents covering certain of our products, and we have filed, and expect to continue to file, patent applications seeking to protect newly developed technologies and products in various countries. Any existing or future patents issued to or licensed by us may not provide us with any significant competitive advantages for our products or may even be challenged, invalidated, or circumvented by competitors. In addition, patent rights may not prevent our competitors from developing, using, or commercializing non-infringing products that are similar or functionally equivalent to our products. • We also rely on trade secrets, unpatented proprietary know-how, and continuing technological innovation that we seek to protect, in part by confidentiality agreements with licensees, suppliers, employees, and consultants. If these agreements are breached, we may not have adequate remedies for any such breach. Disputes may arise concerning the ownership of intellectual property or the applicability of confidentiality agreements. Furthermore, trade secrets and proprietary technology may otherwise become known or be independently developed by competitors or, if patents are not issued with respect to products arising from research, we may not be able to maintain the value of such intellectual property rights. 41 Perrigo Company plc - Item 1A Risk Factors Significant increases in the cost or decreases in the availability of the insurance we maintain could adversely impact our financial condition. To protect the Company against various potential liabilities, we maintain a variety of insurance programs, including property, general and product, and directors' and officers' liability. We may reevaluate and change the types and levels of insurance coverage that we purchase. We are self-insured when insurance is not available or not available at reasonable premiums. Risks associated with insurance plans include: • Insurance costs could increase significantly, or the availability of insurance may decrease, either of which could adversely impact our financial condition; • Deductible or retention amounts could increase or our coverage could be reduced in the future and to the extent losses occur, there could be an adverse effect on our financial results depending on the nature of the loss and the level of insurance coverage we maintained (refer to Item 8. Note 16 for further information related to legal proceedings); • Product liability insurance may not be available to us at an economically reasonable cost (or at all for certain specific products) or our insurance may not adequately cover our liability in connection with product liability claims (refer to Item 8. Note 16 for further information related to legal proceedings); and • As our business inherently exposes us to claims for injuries allegedly resulting from the use of our products, we may become subject to claims for which we are not adequately insured. Unanticipated payment of a large claim may have a material adverse effect on our business. Tax Related Risks The U.S. Internal Revenue Service ("IRS") may not agree with the conclusion that we are treated as a foreign corporation for U.S. federal tax purposes. Although we are incorporated in Ireland, the IRS may assert that we should be treated as a U.S. corporation (and, therefore, a U.S. tax resident) for U.S. federal tax purposes pursuant to section 7874 of the U.S. Internal Revenue Code of 1986, as amended ("Code"). For U.S. federal tax purposes, a corporation generally is considered a tax resident in the jurisdiction of its organization or incorporation. Because we are an Irish incorporated entity, we would generally be classified as a foreign corporation (and, therefore, a non-U.S. tax resident) under these rules. Section 7874 of the Code provides an exception under which a foreign incorporated entity may, in certain circumstances, be treated as a U.S. corporation for U.S. federal tax purposes. For Perrigo Company plc to be treated as a foreign corporation for U.S. federal tax purposes under section 7874 of the Code, either (i) the former stockholders of Perrigo Company must own (within the meaning of section 7874 of the Code) less than 80% (by both vote and value) of our stock by reason of holding shares in Perrigo Company (the "ownership test") as of the closing of the Elan acquisition or (ii) we must have substantial business activities in Ireland after the Elan acquisition (taking into account the activities of our expanded affiliated group). Upon our acquisition of Elan, Perrigo Company stockholders held 71% (by both vote and value) of our shares. As a result, we believe that under current law, we should be treated as a foreign corporation for U.S. federal tax purposes. However, we cannot assure that the IRS will agree with our position that the ownership test is satisfied. There is limited guidance regarding the section 7874 provisions, including the application of the ownership test. An unfavorable determination on Perrigo Company plc’s treatment as a foreign corporation under section 7874 of the Code could have a material impact on our consolidated financial statements in future periods. Based on the limited guidance available, we currently expect that Section 7874 of the Code likely will limit our and our U.S. affiliates’ ability to use their U.S. tax attributes, such as net operating losses, to offset certain U.S. taxable income, if any, generated by the Elan acquisition or certain specified transactions for a period of time following the Elan acquisition (refer to Item 8, Note 14). 42 Perrigo Company plc - Item 1A Risk Factors Changes to tax laws could have a material adverse effect on our results of operations and the ability to utilize cash in a tax efficient manner. We believe that under current law, we should be treated as a foreign corporation for U.S. federal tax purposes. However, any of the following could adversely affect our status as a foreign corporation for U.S. federal tax purposes: • Changes to the inversion rules in section 7874 of the Code, the IRS Treasury regulations promulgated thereunder, or other IRS guidance; and • Legislative proposals aimed at expanding the scope of U.S. corporate tax residence. On April 4, 2016, the United States Treasury ("Treasury") and the IRS issued a package of temporary regulations that incorporate the guidance promised in the 2014 and 2015 notices and provide other rules. These temporary regulations are generally effective for certain inversion transactions completed on or after November 19, 2015 or, in certain cases, to certain specified post-inversion transactions occurring after that date provided that an inversion transaction had occurred on or after September 22, 2014. We do not believe that those regulations would apply to our transaction, which occurred prior to those effective dates. Treasury and the IRS also issued final regulations on June 3, 2015, which address the “substantial business activities” test of Section 7874 of the Code. We believe that those regulations, which have an effective date of June 4, 2015, also do not impact the treatment of our status as a foreign corporation under Section 7874, as our transaction also occurred prior to the effective date of those final regulations. On October 16, 2016, Treasury released final regulations regarding corporate tax inversions and related earnings stripping. These final regulations include provisions that may be interpreted to impact otherwise common tax structures including intercompany financing and obligations. We believe that these regulations do not materially impact our intercompany financing and obligations. Treasury has indicated that they will continue to study certain portions of the proposed regulations that were not finalized, and we will evaluate the impacts of any additional guidance or regulations to our cross-border treasury management practices and intercompany financing structures at that time. We have no assurance that such guidance, if any, will not impact our ability to utilize existing or similar structures in the future. The Organization for Economic Co-operation and Development, which represents a coalition of member countries, has recommended changes to numerous long-standing tax principles relating to Base Erosion and Profit Shifting ("BEPS"). These changes are being adopted and implemented by many of the countries in which we do business and may increase our taxes in these countries. In addition, the European Commission has launched several initiatives to implement BEPS actions including an anti-tax avoidance directive ("ATADI & II") and having a common (consolidated) corporate tax base. It is unclear at present if and how these initiatives will be implemented by the EU countries. Specifically, Ireland is embarking on a consultation process to implement the ATAD & II directives and BEPS related measures. The shape of this reform may adversely impact our consolidated effective tax rate. On December 25, 2017, Belgium enacted a tax reform bill (“Belgium Tax Act”) providing for a simplified tax system including, among other items, a corporate income tax rate reduction from 33% to 29% in 2018 (and to 25% from 2020) and an increase in the participation exemption on qualifying dividends from 95% to 100% (refer to Item 8, Note 14 for further information related to the Belgium Tax Act). On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (“U.S. Tax Act”). The U.S. Tax Act includes a number of significant changes to existing U.S. tax laws that impact us. These changes include a corporate income tax rate reduction from 35% to 21% and the elimination or reduction of certain U.S. deductions and credits, including limitations on the deductibility of interest expense and executive compensation. The U.S. Tax Act also transitions international taxation from a worldwide system to a modified territorial system. This modified territorial system includes, among other items, base erosion prevention measures which have the effect of subjecting certain earnings of our U.S. owned foreign corporations to U.S. taxation as global intangible low-taxed income (“GILTI”) and the establishment of a minimum tax on certain payments from our U.S. subsidiaries to related foreign persons as base erosion and anti-abuse tax (“BEAT”). These changes are effective beginning in 2018. The U.S. Tax Act also includes a one-time mandatory deemed repatriation tax on accumulated U.S. owned foreign 43 Perrigo Company plc - Item 1A Risk Factors corporations’ previously untaxed foreign earnings (“Transition Toll Tax”). The Transition Toll Tax will be paid over an eight-year period starting in 2018 and will not accrue interest. Our preliminary estimate of the impact of the U.S. Tax Act (including the Transition Toll Tax) is subject to the finalization of management's analysis related to certain matters, such as developing interpretations of the provisions of the U.S. Tax Act, changes to certain estimates and amounts related to the earnings and profits of certain U.S. owned foreign subsidiaries and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the U.S. Tax Act may require further adjustments and changes in our estimates, which could have a material adverse effect on our business, results of operations or financial conditions. The final determination of the impact of the U.S. Tax Act (including the Transition Toll Tax) will be completed as additional information becomes available, but no later than one year from the enactment of the U.S. Tax Act (refer to Item 8, Note 14 for further information related to the U.S. Tax Act). Any of these changes could have a prospective or retroactive application to us, our shareholders, and affiliates, and could adversely affect us by changing our effective tax rate and limiting our ability to utilize cash in a tax efficient manner. Our effective tax rate or cash tax payment requirements may change in the future, which could adversely impact our future results from operations. A number of factors may adversely impact our future effective tax rates or cash tax payment requirements, which may impact our future results and cash flows from operations (refer to Item 8. Note 14 for further information related to Income Taxes). These factors include, but are not limited to: • Changes to tax laws or the interpretation of such tax laws (including additional proposals for fundamental international tax reform); Income tax rate changes by governments; • • The jurisdictions in which our profits are determined to be earned and taxed; • Changes in the valuation of our deferred tax assets and liabilities; • Adjustments to estimated taxes upon finalization of various tax returns; • Adjustments to our interpretation of transfer pricing standards, treatment or characterization of intercompany transactions, changes in available tax credits, grants and other incentives; • Changes in stock-based compensation expense; • Changes in U.S. generally accepted accounting principles; • Expiration or the inability to renew tax rulings or tax holiday incentives; • Divestitures of current operations; and • Repatriation of non-U.S. earnings with respect to which we have not previously provided for U.S. taxes. The resolution of uncertain tax positions could be unfavorable, which could have an adverse effect on our business. Although we believe that our tax estimates are reasonable and that our tax filings are prepared in accordance with all applicable tax laws, the final determination with respect to any tax audit or any related litigation could be materially different from our estimates or from our historical income tax provisions and accruals. The results of an audit or litigation could have a material effect on operating results or cash flows in the periods for which that determination is made and in future periods after the determination. In addition, future period earnings may be adversely impacted by litigation costs, settlements, penalties or interest assessments. We are currently involved in several audit and adjustment related disputes, including litigation, with the Internal Revenue Service (“IRS”). These include litigation regarding our 2009, 2010, 2011, and 2012 tax years, as well as proposed audit adjustments related to litigation costs and transfer pricing positions related to Athena Neurosciences, Inc. (“Athena”), a subsidiary of Elan acquired in 1996, for the 2011, 2012 and 2013 tax years. 44 Perrigo Company plc - Item 1A Risk Factors At this time, we cannot predict the outcome of any audit or related litigation. Unfavorable resolutions of the audit matters discussed above could have a material impact on our consolidated financial statements in future periods. (refer to Item 8. Note 14 for further information related to uncertain tax positions and ongoing tax audits and Item 8. Note 16 for further information related to legal proceedings). Risks Related to Capital and Liquidity Our historical failure to timely file our periodic reports with the SEC may limit our options in accessing the public markets to raise debt or equity capital, which in turn may limit our ability to pursue future transactions or strategies. We did not timely file our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 or our Quarterly Report on Form 10-Q for the quarter ended April 1, 2017. As a result, there currently are limits on our ability to access the public markets. For example, we are not eligible to use Form S-3 until we establish the required history of making timely filings for twelve full calendar months. The ability to use Form S-3 to register public offerings in the United States offers certain benefits, such as relatively lower costs and shorter time-frames to prepare a registration statement and cause it to become effective, which may enhance our ability to take advantage of positive market conditions as they develop. The limited availability of access to the public markets could increase the time and costs related to raising capital or prevent us from pursuing transactions or implementing future business strategies. We expect we will again become eligible to use Form S-3 as of June 1, 2018; however, any failure by us to timely file one or more of our periodic reports or otherwise remain current in our SEC reporting requirements may further inhibit our ability to access the public markets. Our indebtedness could adversely affect our ability to implement our strategic initiatives. We anticipate that cash, cash equivalents, cash flows from operations, and borrowings available under our credit facilities will substantially fund working capital and capital expenditures. Our business requires continuous capital investments, and there can be no assurance that financial capital will always be available on favorable terms or at all. Additionally, our leverage and debt service obligations could adversely affect the business. At December 31, 2017, our total indebtedness outstanding was $3.3 billion. • Our senior credit facilities, the agreements governing our senior notes, and agreements governing our other indebtedness contain a number of restrictions and covenants that limit our ability to make distributions or other payments to our investors and creditors unless certain financial tests or other criteria are satisfied. • We also must comply with certain specified financial ratios and tests. These restrictions could affect our ability to operate our business and may limit our ability to take advantage of potential business opportunities, such as acquisitions. If we do not comply with the covenants and restrictions contained in our senior credit facilities, agreements governing our senior notes, and agreements governing our other indebtedness, we could be in default under those agreements, and the debt, together with accrued interest, could then be declared immediately due and payable. • Any default under our senior credit facilities or agreements governing our senior notes or other indebtedness could lead to an acceleration of debt under other debt instruments that contain cross- acceleration or cross-default provisions. If our indebtedness is accelerated, there can be no assurance that we would be able to repay or refinance our debt or obtain sufficient new financing. • Downgrades to our credit ratings may limit our access to capital and materially increase borrowing costs on current or future financing, including via trade payables with vendors. Customers' inclination to purchase goods from us may also be affected by the publicity associated with deterioration of our credit ratings. • There are various maturity dates associated with our credit facilities, senior notes, and other debt facilities. There is no assurance that cash, future borrowings or equity financing will be available for the payment or refinancing of our indebtedness. Further, there is no assurance that future refinancing or renegotiation of our senior credit facilities, senior notes or other debt facilities, or additional agreements will not have materially different or more stringent terms (refer to Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations). 45 Perrigo Company plc - Item 1A Risk Factors We cannot guarantee that we will buy back our ordinary shares pursuant to our announced share repurchase plan or that our share repurchase plan will enhance long-term shareholder value. In October 2015, our Board of Directors authorized a $2.0 billion three-year share repurchase plan. During the three months ended December 31, 2015, we repurchased shares through the plan totaling $500.0 million. During 2016, we did not purchase any shares in the open market. During 2017, we repurchased $191.5 million worth of shares. The specific timing and amount of buybacks, if any, will depend upon several factors, including market and business conditions, the trading price of our ordinary shares, and the nature of other investment opportunities. Buybacks of our ordinary shares pursuant to our share repurchase plan could affect the market price of our ordinary shares or increase their volatility. Additionally, our share repurchase plan could diminish our cash reserves, which may impact our ability to finance future growth and to pursue possible future strategic opportunities and acquisitions. Although our share repurchase plan is intended to enhance long-term shareholder value, there is no assurance that it will do so, and short-term share price fluctuations could reduce the plan’s effectiveness. Any additional shares we may issue could dilute your ownership in the Company. • Under Irish law, our authorized share capital can be increased by an ordinary resolution of our shareholders, and the directors may issue new ordinary or preferred shares up to a maximum amount equal to the authorized but unissued share capital, without shareholder approval, once authorized to do so by the articles of association or by an ordinary resolution of our shareholders. • Subject to specified exceptions, Irish law grants statutory preemption rights to existing shareholders to subscribe for new issuances of shares for cash, but allows shareholders to authorize the waiver of the statutory preemption rights by way of special resolution with respect to any particular allotment of shares. • Our articles of association contain, as permitted by Irish company law, a provision authorizing our Board of Directors to issue new shares for cash without offering preemption rights. The authorization of the directors to issue shares and the authorization of the waiver of the statutory preemption rights must both be renewed by the shareholders at least every five years, and we cannot provide any assurance that these authorizations will always be approved, which could limit our ability to issue equity and thereby adversely affect the holders of our securities. We are incorporated in Ireland; Irish law differs from the laws in effect in the United States and may afford less protection to, or otherwise adversely affect, our shareholders. As an Irish company, we are governed by the Irish Companies Act 2014 (the "Act"). The Act differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including the provisions relating to interested directors, mergers, amalgamations and acquisitions, takeovers, shareholder lawsuits, and indemnification of directors. • Under Irish law, the duties of directors and officers of a company are generally owed to the company only. As a result, shareholders of Irish companies do not have the right to bring an action against the directors or officers of a company, except in limited circumstances. • Depending on the circumstances, shareholders may be subject to different or additional tax consequences under Irish law as a result of the acquisition, ownership and/or disposition of ordinary shares, including, but not limited to, Irish stamp duty, dividend withholding tax, and capital acquisitions tax. • There is no treaty between Ireland and the U.S. providing for the reciprocal enforcement of foreign judgments. Before a foreign judgment would be deemed enforceable in Ireland, the judgment must be provided by a court of competent jurisdiction and be for a final and conclusive sum. An Irish court may exercise its right to refuse to recognize and enforce a foreign judgment if the foreign judgment was obtained by fraud, if it violated Irish public policy, if it is in breach of natural justice, or if it is irreconcilable with an earlier judgment. 46 Perrigo Company plc - Item 1A Risk Factors • An Irish court may stay proceedings if concurrent proceedings are being brought elsewhere. Judgments of U.S. courts of liabilities predicated upon U.S. federal securities laws may not be enforced by Irish courts if deemed to be contrary to public policy in Ireland. We are subject to Irish takeover rules under which our Board of Directors is not permitted to take any action without shareholder or Irish Takeover Panel approval that might frustrate an offer for our ordinary shares once we have received an approach that may lead to an offer, or have reason to believe an offer is or may be imminent. Further, it could be more difficult for us to obtain shareholder approval for a merger or negotiated transaction than if we were a U.S. company because the shareholder approval requirements for certain types of transactions differ, and in some cases are greater, under Irish law. We may be limited in our ability to pay dividends in the future. A number of factors may limit our ability to pay dividends in the future, including: • The availability of distributable reserves, as approved by our shareholders and the Irish High Court; • Our ability to receive cash dividends and distributions from our subsidiaries; • Compliance with applicable laws and debt covenants; and • Our financial condition, results of operations, capital requirements, general business conditions, and other factors that our Board of Directors may deem relevant.

Unless the context requires otherwise, the terms "Perrigo," the "Company," "we," "our," "us," and similar pronouns used herein refer to Perrigo Company plc, its subsidiaries, and all predecessors of Perrigo Company plc and its subsidiaries. We are a leading global healthcare company, delivering value to our customers and consumers by providing Quality Affordable Healthcare Products®. Founded in 1887 as a packager of home remedies, we have built a unique business model that is best described as the convergence of a fast-moving consumer goods company, a high-quality pharmaceutical manufacturing organization and a world-class supply chain network. We believe we are one of the world's largest manufacturers of over-the-counter (“OTC”) healthcare products and suppliers of infant formulas for the store brand market. We are a leading provider of branded OTC products throughout Europe, and also a leading producer of generic pharmaceutical topical products such as creams, lotions, and gels, as well as nasal sprays and injection ("extended topical") prescription drugs. We are headquartered in Ireland, and sell our products primarily in North America and Europe, as well as in other markets, including Australia, Israel and China. Our fiscal year previously consisted of a 52- or 53-week year ending on or around June 30 of each year with each quarter ending on the Saturday closest to each calendar quarter end. Beginning on January 1, 2016, we changed our fiscal year to begin on January 1 and end on December 31 of each year. As a result of our change in year end, this report on Form 10-K discloses the results of our operations for: • The twelve-month period from January 1, 2017 through December 31, 2017; • The twelve-month period from January 1, 2016 through December 31, 2016; • The twelve-month period from January 1, 2015 through December 31, 2015; • The six-month period from June 28, 2015 through December 31, 2015; and • The six-month period from June 29, 2014 through December 27, 2014. Calendar-year data for 2015 was derived from our audited results for the six-month period ended December 31, 2015 and unaudited results for the fiscal quarters ended March 28, 2015 and June 27, 2015. We cut off our quarterly accounting periods on the Saturday closest to the end of the calendar quarter, with the fourth quarter ending on December 31 of each year. Our Segments Our reporting segments are as follows: • Consumer Healthcare Americas ("CHCA"), comprises our U.S., Mexico and Canada consumer healthcare business (OTC, contract, infant formula and animal health categories). • Consumer Healthcare International ("CHCI"), comprises our branded consumer healthcare business primarily in Europe and our consumer focused businesses in the U.K., Australia, and Israel. This segment also includes our U.K. liquid licensed products business. • Prescription Pharmaceuticals ("RX"), comprises our U.S. Prescription Pharmaceuticals business. We also had two legacy operating segments, Specialty Sciences and Other, which contained our Tysabri® financial asset and Active Pharmaceuticals business ("API") businesses, respectively, which we divested (refer to Item 8. Note 2 and Note 6). Following these divestitures, there were no substantial assets or operations left in either of these segments. Effective January 1, 2017, all expenses associated with our former Specialty Sciences segment were moved to unallocated expenses. Our segments reflect the way in which our management makes operating decisions, allocates resources and manages the growth and profitability of the Company. For information on each segment, refer to Item 1. Business - Our Segments. For results by segment and geographic locations see below "Segment Results" and Item 8. Note 19. See Item 1. Business for information on our business environment and competitive landscape. 53 Perrigo Company plc - Item 7 Executive Overview Strategy Our strategy is to deliver Quality Affordable Healthcare Products® by leveraging our global infrastructure to expand our product offerings, thereby providing new innovative products and product line extensions to existing consumers and servicing new healthcare consumers through entry into adjacent or new markets. We accomplish this strategy by investing in and continually improving all aspects of our five strategic pillars: • High quality; • Superior customer service; • • Best cost; and • Empowered people. Leading innovation; We utilize shared services and Research and Development ("R&D") centers of excellence in order to help ensure consistency in our processes around the world, and to maintain focus on our five strategic pillars. We have grown rapidly in recent years through a combination of organic growth and targeted acquisitions. We continually reinvest in our R&D pipeline and work with partners as necessary to strive to be first-to-market with new products. Our organic growth has been and will continue to be driven by successful new product launches in the CHCA, CHCI, and RX segments. Over time, we expect to continue to grow inorganically through expansion into adjacent products, product categories, and channels, as well as potentially through entry into new geographic markets. We evaluate potential acquisition targets using a return on invested capital ("ROIC") metric. Competitive Advantage We believe our consumer facing business model is best-in-class in that it combines the unique competencies of a fast-moving consumer goods company and a pharmaceutical manufacturing company, with the supply chain breadth necessary to support customers in the markets we serve. These durable business model competencies align with our five strategic pillars and provide us a competitive advantage in the marketplace. We fully integrate quality in our operational systems across all products. Our ability to manage our supply chain complexity across multiple dosage forms, formulations, and stock-keeping units, as well as acquisitions, integration, and hundreds of global partners provides value to our customers. Product development and life cycle management are at the core of our operational investments. Globally we have 28 manufacturing plants that are all in good regulatory compliance standing and have systems and structures in place to guide our continued success. Our leadership team is fully engaged in aligning all our metrics and objectives around sustainable compliance with industry associations and regulatory agencies. Among other things, we believe the following give us a competitive advantage and provide value to our customers: Leadership in first-to-market product development and product life cycle management; • • Turn-key regulatory, and promotional capabilities; • Management of supply chain complexity and utilizing economies of scale; • Quality and cost effectiveness throughout the supply chain creating a sustainable, low-cost network; and • Expansive pan-European commercial infrastructure, brand-building capabilities, and a diverse product portfolio. 54 Perrigo Company plc - Item 7 Executive Overview Highlights Year Ended December 31, 2017 • On March 27, 2017, we completed the sale of our Tysabri® financial asset, effective January 1, 2017, to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively.

Restructuring On February 21, 2017, we approved a workforce reduction plan as part of a larger cost optimization strategy across the Company, which was completed during the year. Our plan was to reduce our global workforce by approximately 750 employees, which included some actions already taken and 235 employees who had elected to participate in a voluntary early retirement program. This represented a reduction of approximately 14% of our global non-production workforce. The changes to our workforce varied by country, based on legal requirements and required consultations with works councils and other employee representatives, as appropriate. During the year ended December 31, 2017, we recognized $61.0 million of restructuring expenses (refer to Item 8. Note 18). In addition, during the year ended December 31, 2017, we executed a supply chain reorganization which continues to generate savings for both our North American and International segments. Impairments Throughout the years ended December 31, 2017 and December 31, 2016, we identified impairment indicators for various assets across our different segments, and therefore, we performed impairment testing.

The year-over-year effect of the cancellation, combined with the 61 Perrigo Company plc - Item 7 CHCI exit of certain OTC distribution agreements, reduced our net sales by $200.3 million in 2017, with an immaterial impact to operating income. • We made progress on our previously announced restructuring plans to right-size the Omega business due to the impact of market dynamics on sales volumes. During the year ended December 31, 2017, we recognized $17.1 million of restructuring expense in the CHCI segment (refer to Item 8. Note 18). • Management continues to evaluate the most effective business model for each country, aligning our sales infrastructure and actively integrating sales strategies with promotional programs. • On August 25, 2017, we completed the sale of our Russian business, which was previously classified as held-for-sale, to Alvogen Pharma LLC. The total sale price was €12.7 million ($15.1 million), inclusive of an estimated working capital adjustment, which resulted in an immaterial gain in the segment (refer to Item 8. Note 2). The combination of these actions improved the segment's focus on higher value OTC products, reduced selling costs and improved operating margins in the segment. • The CHCI segment has been positively impacted by market dynamics in countries such as the Nordics, Italy, and Portugal offset by softness in certain brand categories in France and Germany, as well as by unfavorable foreign currency impacts primarily in the U.K. related to Brexit.

Operating income decreased $162.6 million, due to: • A $330.1 million increase in gross profit and a $492.7 million increase in operating expenses due to an additional six months of operations attributable to Omega. PRESCRIPTION PHARMACEUTICALS Recent Trends and Developments • We continue to experience a significant reduction in pricing expectations from historical levels in our RX segment due to competitive pressures. This softness in pricing is attributable to various factors, including increased focus from customers to capture supply chain productivity savings, competition in specific products, and consolidation of certain customers. We expect this softness to continue to impact the segment for the foreseeable future, and we are forecasting a high single digit pricing decline in this segment for the year ending December 31, 2018. 64 Perrigo Company plc - Item 7 RX • During the three months ended December 31, 2016, the U.S. market for Entocort® (Budesonide) capsules, including both brand and authorized generic capsules, experienced significant and unexpected increased competition, which reduced our future revenue stream. As a result, our net sales in the RX segment for the year ended December 31, 2017 were negatively impacted by $67.2 million. • We are continuing our previously announced portfolio review process, which includes the ongoing comprehensive internal evaluation of the RX segment's market position, growth opportunities, and interdependencies with our manufacturing and shared service operations to determine if strategic alternatives should be explored. • During the year ended December 31, 2017, we sold various Abbreviated New Drug Applications ("ANDAs") for a total gain of $23.0 million.

SPECIALTY SCIENCES Recent Trends and Developments • On March 27, 2017, we announced the completed divestment of our Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017. We elected to account for the contingent milestone payments using the fair value option method, and these were recorded at an estimated fair value of $134.5 million as of December 31, 2017 (refer to Item 8. Note 6 and Critical Accounting Estimates for additional information on the contingent milestones). Segment Results Year Ended December 31, 2016 vs. Year Ended December 31, 2015 Operating expenses were $201.2 million for the year ended December 31, 2015, compared to $15.0 million for the prior year period. The decreases of $186.2 million primarily relates to a $199.6 million impairment charge related to the Tysabri® goodwill (refer to Item 8. Note 3). 67 Perrigo Company plc - Item 7 Specialty Sciences Six Months Ended December 31, 2015 vs. Six Months Ended December 27, 2014 Operating expenses were $6.5 million for the six months ended December 31, 2015, compared to $9.0 million for the prior year period. The decreases of $2.5 million was due to a reduction in legal expenses. See the Interest, Other and Change in financial asset (Consolidated) section below for discussions on the Tysabri® financial asset. OTHER Recent Trends and Developments On April 6, 2017, we completed the sale of our India API business to Strides Shasun Limited. We received $22.2 million of proceeds, inclusive of an estimated working capital adjustment, which resulted in an immaterial gain. Prior to closing the sale, we determined that the carrying value of the India API business exceeded its fair value less the cost to sell, resulting in an impairment charge of $35.3 million, which was recorded in Impairment charges on the Consolidated Statements of Operations for the year ended December 31, 2016 (refer to Item 8. Note 2). On November 21, 2017, we completed the sale of our Israel API business, which was previously classified as held-for-sale, to SK Capital for a sale price of $110.0 million, which resulted in an immaterial gain recorded in our Other segment in Other expense (Income), net on the Consolidated Statements of Operations (refer to Item 8.

Operating income increased $2.6 million due to a $1.4 million decrease in gross profit due primarily to a decrease in sales of existing products offset by a $4.0 million decrease in operating expenses. The decrease in operating expenses related primarily to the absence of a $8.3 million impairment charge recorded on the India API business and certain definite-lived intangible assets in the prior year; offset partially by a $3.3 million impairment charge recorded on the Israel API business in the current period. 68 Year Ended December 31, 2016 vs. Year Ended December 31, 2015 Perrigo Company plc - Item 7 Other ($ in millions) Net sales Gross profit Gross profit % Operating income (loss) Operating income (loss) % Year Ended December 31, 2015 December 31, 2016 $ $ $ $ $ $ 98.0 44.7 45.5 % (7.1) (7.3)% 78.5 32.3 41.2% 6.1 7.8% Net sales decreased $19.5 million due primarily to competition on certain products, in particular, U.S. sales of Temozolomide.

Unallocated Expenses Unallocated expenses are comprised of certain corporate services not allocated to our reporting segments and are recorded above Operating income on the Consolidated Statements of Operations. Unallocated expenses were as follows (in millions): Six Months Ended Year Ended December 27, 2014 December 31, 2015 December 31, 2015 December 31, 2016 December 31, 2017 $ 49.6 $ 149.0 $ 220.9 $ 116.6 $ 174.7 69 Perrigo Company plc - Item 7 Other The $58.1 million increase for the year ended December 31, 2017 compared to the prior year was due primarily to an increase in share-based compensation expense of $12.6 million driven primarily by the resignation of certain executives, an increase of $41.1 million of administrative expenses driven by legal fees, consulting fees and employee-related expenses, and an increase in restructuring of $6.0 million related to strategic organizational enhancements (refer to Item 8. Note 15). The $104.3 million decrease for the year ended December 31, 2016 compared to the prior year was due primarily to the absence of legal and professional fees related to our defense against the unsolicited takeover bid by Mylan of $100.3 million and Omega acquisition-related fees of $18.1 million. We also experienced a $15.0 million reduction in share-based compensation compared to the prior year due primarily to the resignation of our former Chief Executive Officer, Joseph C. Papa. These decreases were offset partially by a $36.2 million increase in legal and professional fees in the current year. The $99.4 million increase for the six months ended December 31, 2015 compared to the prior year period was due primarily to $86.9 million in fees incurred in our defense against the unsolicited takeover bid by Mylan and $7.5 million in corporate restructuring charges.

Royalty rights were $24.9 million of expense, $2.6 billion of expense and $88.8 million of income for the years ended December 31, 2017, December 31, 2016 and December 31, 2015, respectively. Royalty rights were $57.3 million of income and $46.9 million of income for the six months ended December 31, 2015 and December 27, 2014, respectively. Royalty rights were $78.5 million of income and $26.6 million of income for the years ended June 27, 2015 and June 28, 2014, respectively, resulting in a change in financial asset of $2.6 billion, $2.7 billion, $10.4 million, and $51.9 million for the year ended December 31, 2017, December 31, 2016, six months ended December 31, 2015, and the year ended June 27, 2015 compared to the prior year periods, respectively (refer to Item 8. Note 6 for additional information on the assumptions). In the first quarter of 2016, a competitor's pipeline product, Ocrevus®, received breakthrough therapy designation from the U.S. Food and Drug Administration ("FDA"). Breakthrough therapy designation is granted when a drug is intended alone or in combination with one or more other drugs to treat a serious or life threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. In June 2016, the FDA granted priority review with a target action date in December 2016. A priority review is a designation when the FDA will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. The product was approved late in the first quarter of 2017. The product is expected to compete with Tysabri®, and we expected it to have a significant negative impact on the Tysabri® royalty stream. Industry analysts believe that, based on released clinical study information, Ocrevus® will compete favorably against Tysabri® in the relapsing, remitting multiple sclerosis market segment due to its high efficacy and convenient dosage form. 70 Perrigo Company plc - Item 7 Unallocated, Interest, Other, and Taxes Given the new market information for Ocrevus®, we used industry analyst estimates to reduce our first ten year growth forecasts from an average growth of approximately 3.4% in the fourth calendar quarter of 2015 to an average decline of approximately minus 2.0% in the third and fourth calendar quarters of 2016. In November 2016, we announced we were evaluating strategic alternatives for the Tysabri® financial asset. As of December 31, 2016, the financial asset was adjusted based on the strategic review and sale process. These effects, combined with the change in discount rate each quarter, led to a reduction in fair value of $204.4 million, $910.8 million, $377.4 million and $1.1 billion in the first, second, third and fourth quarters of 2016, respectively. On March 27, 2017, we announced the completed divestment of our Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017. We elected to account for the contingent milestone payments using the fair value option method, and these were recorded at an estimated fair value of $134.5 million as of December 31, 2017. We chose the fair value option as we believe it will help investors understand the potential future cash flows we may receive associated with the two contingent milestones. We valued the contingent milestone payments using a modified Black-Scholes Option Pricing Model ("BSOPM"). Key inputs in the BSOPM are the estimated volatility and rate of return of royalties on global net sales of Tysabri® that are received by Royalty Pharma over time until payment of the contingent milestone payments is completed. Volatility and the estimated fair value of the milestones have a positive relationship such that higher volatility translates to a higher estimated fair value of the contingent milestone payments. In the valuation of contingent milestone payments performed, we assumed volatility of 30.0% and a rate of return of 8.07% as of December 31, 2017. We assess volatility and rate of return inputs quarterly by analyzing certain market volatility benchmarks and the risk associated with Royalty Pharma achieving the underlying projected royalties. During the year ended December 31, 2017, the fair value of the Royalty Pharma contingent milestone payments decreased $42.0 million, as a result of the decrease in the estimated projected Tysabri® revenues due to the launch of Ocrevus® late in the first quarter of 2017. In addition, payment of the contingent milestone payments is dependent on global net sales of Tysabri®. Of the $134.5 million of estimated fair valued contingent milestone payments as of December 31, 2017, $79.7 million and $54.8 million relates to the 2018 and 2020 contingent milestone payments, respectively. If Tysabri® global net sales do not meet the prescribed threshold in 2018, we will write off the $79.7 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $250.0 million and recognize income of $170.3 million in Change in financial assets on the Consolidated Statement of Operations. If Tysabri® global net sales do not meet the prescribed threshold in 2020, we will write off the $54.8 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $400.0 million and recognize income of $345.2 million in Change in financial assets on the Consolidated Statement of Operations. Global Tysabri® net sales need to exceed $1.9 billion and $2.0 billion in 2018 and 2020, respectively, in order for Royalty Pharma to receive the level of royalties needed to trigger the milestone payments owed to us. Tysabri® net sales are anticipated to decline on a global basis in 2018, compared to 2017, due to increased competition from Ocrevus®, offset by volume growth in Tysabri® international markets (refer to Item 8. Note 6). Interest Expense, Net Interest expense, net was $168.1 million for the year ended December 31, 2017, compared to $216.6 million in the prior year. The $48.5 million decrease for the year ended December 31, 2017 compared to the prior year was the result of the early debt repayments made during the year ended December 31, 2017. Interest expense, net was $216.6 million for the year ended December 31, 2016, compared to $179.1 million in the prior year. The $37.5 million increase for the year ended December 31, 2016 compared to the prior year was due to interest incurred on the debt assumed in the Omega acquisition and borrowings on our revolving credit agreements during the year ended December 31, 2016. 71 Perrigo Company plc - Item 7 Unallocated, Interest, Other, and Taxes Interest expense, net was $89.9 million for the six months ended December 31, 2015, compared to $56.7 million in the prior year period. The $33.2 million increase for the six months ended December 31, 2015 compared to the prior year period was due primarily to the incremental increase in borrowings resulting from the Omega acquisition, including the issuance of $1.6 billion of senior notes in November 2014 and assumed Omega debt, of which $798.3 million was outstanding at December 31, 2015, as well as amounts drawn under our revolving credit facilities, including $380.0 million and $300.0 million outstanding under the 2015 Revolver and 2014 Revolver, respectively, at December 31, 2015. See the "Borrowings and Capital Resources" section below and Item 8. Note 10 for more information. Other Expense (Income), Net Other expense (Income), net, was $10.1 million for the year ended December 31, 2017, compared to $22.7 million in the prior year. The $32.8 million decrease was due primarily to the absence of a $22.3 million equity investment impairment, $8.2 million of favorable changes in revaluation of monetary assets and liabilities held in foreign currencies, and a $3.2 million reduction in equity method losses. Other expense (Income), net, was $22.7 million for the year ended December 31, 2016, compared to $299.1 million in the prior year. The $276.4 million decrease was due primarily to the absence of the $259.8 million loss incurred in the prior year on the derivatives used to economically hedge fluctuations in the euro-denominated purchase price of the Omega and GSK Products acquisitions. The losses on the derivatives due to the changes in the EUR/USD exchange rate prior to their settlement economically offset the final settlement of the euro- denominated Omega purchase price paid on March 30, 2015. Other expense (Income), net, was $25.2 million for the six months ended December 31, 2015, compared to $60.3 million in the prior year period. The $35.1 million decrease was due primarily to a $10.7 million other-than- temporary impairment of a marketable equity security, losses on equity method investments totaling $7.1 million, and a $4.8 million loss on a foreign currency derivative we entered into, to hedge against the change in the euro for the euro-denominated purchase price of the GSK Products acquisition, offset by the absence of a $64.7 million loss related to derivative activity to economically hedge fluctuations in the euro-denominated purchase price of the Omega acquisition and a gain of $12.5 million from the transfer of a rights agreement. See Item 8. Note 8 for more information on the derivatives and Item 8. Note 7 for information on the investments. Loss on Extinguishment of Debt During the year ended December 31, 2017, we recorded a $135.2 million loss on extinguishment of debt, which consisted of tender premium on debt repayments, transaction costs, write-off of deferred financing fees, and bond discounts related to the $500.0 million 3.500% senior notes due December 2021, $500.0 million 3.500% senior notes due March 2021, $400.0 million 4.900% senior notes due 2044, $800.0 million 4.000% senior notes due 2023, and $400.0 million 5.300% senior notes due 2043. During the year ended December 31, 2016, we recorded a $1.1 million loss on extinguishment of debt, which consisted of deferred financing fees we wrote off primarily related to the prepayment of 1.300% 2016 Notes. During the six months and year ended December 31, 2015 we recorded a $0.9 million and $1.8 million loss on extinguishment of debt, respectively, which consisted of deferred financing fees we wrote off related to the undrawn tranche of certain credit facilities that we allowed to expire during the period. The $9.6 million and $10.5 million losses during the six months and year ended December 27, 2014 and June 27, 2015, respectively, consisted mainly of interest on the bridge agreement associated with financing the Omega acquisition. The $165.8 million loss recorded in the year ended June 28, 2014 consisted of make-whole payments, write-off of unamortized discounts, write-off of deferred financing fees, and interest on the bridge agreements associated with financing the Elan acquisition. See Item 8. Note 2 for information on the Omega acquisition, and Item 8. Note 10 for information on the extinguishment of debt. 72 Perrigo Company plc - Item 7 Unallocated, Interest, Other, and Taxes Income Taxes (Consolidated) The effective tax rates were as follows: Six Months Ended Year Ended December 27, 2014 December 31, 2015 December 31, 2015 December 31, 2016 December 31, 2017 14.0% (376.2)% 103.3% 17.2% 57.3% The effective tax rate for the year ended December 31, 2017 was higher compared to the year ended December 31, 2016 due to an increase in the valuation allowance position due to current year activity, tax law changes in the U.S., increases in unrecognized tax benefits, offset by tax law changes in Belgium. The effective tax rate for the year ended December 31, 2016 was lower compared to the year ended December 31, 2015 due to the impact of the asset impairments recorded during the year ended December 31, 2016. The effective tax rate for the year ended December 31, 2015 was impacted by the impairment of Omega's intangible assets, India API assets being classified as held for sale, the valuation allowance on deferred taxes and Omega transaction costs. The effective tax rate for the six months ended December 31, 2015 was significantly higher than for the six months ended December 27, 2014 due mainly to the impairment of Omega’s intangible assets and the related impacts on the valuation allowance position, as well as our India API assets being classified as held for sale. The effective tax rate was favorably affected by a reduction in the reserves for uncertain tax liabilities in the amount of $6.1 million for the six months ended December 31, 2015 related to various audit resolutions. For the year ended December 31, 2017, statutory income tax rate changes in the U.S. and Belgium impacted the effective tax rate with a reduction to U.S. income tax expense of $2.4 million and increased Belgium income tax expense by $24.1 million. For the years ended December 31, 2016 and December 31, 2015, statutory income tax rate changes, primarily in Europe, favorably impacted the effective tax rate by $27.9 million and $4.0 million, respectively (refer to Item 8. Note 14). FINANCIAL CONDITION, LIQUIDITY, AND CAPITAL RESOURCES We finance our operations with internally generated funds, supplemented by credit arrangements with third parties and capital market financing. We routinely monitor current and expected operational requirements and financial market conditions to evaluate other available financing sources including revolving bank credit and securities offerings. Based on our current financial condition and credit relationships, management believes that our operations and borrowing resources are sufficient to provide for our current and foreseeable capital requirements. However, we continue to evaluate the impact of commercial and capital market conditions on liquidity and may determine that modifications to our capital structure are appropriate if market conditions deteriorate or if favorable capital market opportunities become available. 73 Cash and Cash Equivalents Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources * Working capital represents current assets less current liabilities, excluding cash and cash equivalents, and current indebtedness. Cash, cash equivalents, cash flows from operations, and borrowings available under our credit facilities are expected to be sufficient to finance the known and/or foreseeable liquidity and capital expenditures. Although our lenders have made commitments to make funds available to us in a timely fashion under our revolving credit agreements and overdraft facilities, if economic conditions worsen or new information becomes publicly available impacting the institutions’ credit rating or capital ratios, these lenders may be unable or unwilling to lend money pursuant to our existing credit facilities.

Note 16), and fair market value adjustments related to contingent consideration (refer to Item 8. Note 6); offset partially by • Changes in inventory due to the build up of inventory levels to support customer demands in the current period; offset by improved inventory management in the comparable prior year period; and • Changes in accrued income taxes due primarily to Federal tax obligation payments made in the current year period, offset by expected tax refunds (refer to Item 8.

Note 14). In addition, increased net earnings after adjusting for non-cash items such as impairment charges, loss on extinguishment of debt, changes in our financial assets, and depreciation and amortization contributed to an increase in operating cash flow.

Note 14); offset partially by • Changes in accrued liabilities due primarily to amounts not yet paid related to our defense against Mylan; • Changes in accounts receivable due to timing of receipt of payments; and • Increased net earnings after adjusting for non-cash items such as impairment charges, changes in our financial assets, and depreciation and amortization. 76 Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources In addition, our operating cash flow was negatively impacted by $57.7 million in legal and consulting fees related to our defense against Mylan. Due to the acquisition of Omega on March 30, 2015, our CHCI segment experienced strong operating cash inflow in the second quarter of 2015 and cash outflow in the third quarter of 2015 primarily due to accounts payable payment structures with suppliers that increased the days outstanding in the second and fourth quarter compared to the first and third quarters. In order to establish a more sustainable cash flow pattern during the calendar year, in the fourth quarter of 2015 and continuing into the first quarter of 2016, we implemented a program to standardize these payment terms such that the days outstanding will largely be consistent each reporting period. This program had an unfavorable impact on accounts payable and operating cash flow in these quarters.

The inflow in the current year was due primarily to the completed divestment of our Tysabri® financial asset to Royalty Pharma, for which we received $2.2 billion in cash at closing (refer to Item 8. Note 6). In addition, we received $154.6 million in cash primarily related to the sale of our Israel API business (refer to Item 8. Note 2). The outflow in the prior year was due primarily to the acquisition of a portfolio of generic dosage forms and strengths of Retin-A® ("Tretinoin"), a topical prescription acne treatment from Mattawan Pharmaceuticals, LLC, and the Generic Benzaclin™ product rights, which used $478.4 million in cash. The outflow was offset partially by proceeds from royalty rights of $353.7 million. Cash used for capital expenditures totaled $88.6 million during the year ended December 31, 2017 compared to $106.2 million in the prior year. The decrease in cash used for capital expenditures was due primarily to the decrease in the number of manufacturing projects in the current year compared to the prior year. Capital expenditures for the next twelve months are anticipated to be between $90.0 million and $115.0 million related to manufacturing productivity capacity and quality/regulatory projects. We expect to fund these estimated capital expenditures with funds from operating cash flows. 77 Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources Year Ended December 31, 2016 vs. Year Ended December 31, 2015 ($ in millions) Cash Flows From (For) Investing Activities Year Ended December 31, 2015 December 31, 2016 Increase/ (Decrease) Proceeds from royalty rights $ 335.1 $ 353.7 $ Acquisitions of businesses, net of cash acquired Asset acquisitions Settlement of acquisition-related foreign currency derivatives Proceeds from sale of securities Additions to property, plant and equipment Proceeds from sale of business Other investing, net (2,886.4) (4.0) (304.8) — (166.8) — (2.7) (427.4) (65.1) — 4.5 (106.2) 69.1 (3.6) 18.6 2,459.0 (61.1) 304.8 4.5 60.6 69.1 (0.9) Net cash from (for) investing activities $ (3,029.6) $ (175.0) $ 2,854.6 Cash used for investing activities totaled $175.0 million for the year ended December 31, 2016, a $2.9 billion decrease over the prior year. The outflow in the year ended December 31, 2016 was due primarily to the acquisitions of the Tretinoin Products and the Generic Benzaclin™ product rights, which used $478.4 million in cash, offset partially by $353.7 million of proceeds from royalty rights. The outflow in the prior year was due primarily to $2.9 billion used for business acquisitions, most notably Omega, as well as $304.8 million related to the cash settlement of the non-designated foreign currency derivatives we used to hedge the euro-denominated Omega and GSK Products purchase prices. See Item 8. Note 2 and Item 8. Note 8 for more information on the above- mentioned acquisitions and derivatives, respectively. Cash used for capital expenditures totaled $106.2 million during year ended December 31, 2016 compared to $166.8 million in the prior year.

The balance outstanding under the facilities was $6.9 million and $82.9 million at December 31, 2017 and December 31, 2015, respectively, and there were no balances outstanding under the facilities at December 31, 2016. On March 30, 2015, we assumed and repaid certain overdraft facilities totaling €51.4 million ($56.0 million) with the Omega acquisition. Accounts Receivable Factoring We have accounts receivable factoring arrangements with non-related third-party financial institutions (the “Factors”). Pursuant to the terms of the arrangements, we sell to the Factors certain of our accounts receivable balances on a non-recourse basis for credit approved accounts. An administrative fee per invoice is charged on the gross amount of accounts receivables assigned to the Factors, and interest is calculated at the applicable EUR LIBOR rate plus a spread. The total amount factored on a non-recourse basis and excluded from accounts receivable was $27.5 million, $50.7 million, and $64.5 million at December 31, 2017, December 31, 2016 and December 31, 2015, respectively. Revolving Credit Agreements On December 9, 2015, our 100% owned finance subsidiary, Perrigo Finance Unlimited Company (formerly Perrigo Finance plc) ("Perrigo Finance"), entered into a $750.0 million revolving credit agreement (the "2015 Revolver"). On March 15, 2016, we used the proceeds of the long-term debt issuance described below under "2016 Notes" to repay the $750.0 million then outstanding under the 2015 Revolver and terminated the facility. On March 30, 2015, we assumed a revolving credit facility with €500.0 million ($544.5 million) outstanding from Omega. On April 8, 2015, we repaid the €500.0 million ($539.1 million) outstanding under the assumed revolving credit facility and terminated the facility. On December 5, 2014, Perrigo Finance entered into a $600.0 million revolving credit agreement, which increased to $1.0 billion on March 30, 2015 (the "2014 Revolver"). On March 15, 2016, we used the proceeds of the long-term debt issuance described below under "2016 Notes" to repay the $435.0 million then outstanding under the 2014 Revolver. There were no borrowings outstanding under the 2014 Revolver as of December 31, 2017 or December 31, 2016. Term Loans, Notes and Bonds • We had $2.9 billion, $5.4 billion, and $4.7 billion outstanding under our notes and bonds, and $420.0 million, $420.7 million, and $488.8 million outstanding under our term loan, as of December 31, 2017, December 31, 2016, and December 31, 2015, respectively. On September 29, 2016, we repaid the 1.300% senior notes due 2016 in full. • On March 7, 2016, Perrigo Finance issued $500.0 million in aggregate principal amount of 3.500% senior notes due 2021 and $700.0 million in aggregate principal amount of 4.375% senior notes due 2026 (together, the "2016 Notes") and received net proceeds of $1.2 billion after fees and market discount, which were used to repay the amounts outstanding under the 2015 Revolver and 2014 Revolver mentioned above. • On September 2, 2014, we offered to exchange what were previously private placement senior notes for public bonds registered with the Securities and Exchange Commission. Substantially all of the private placement senior notes have been exchanged. • On December 2, 2014, Perrigo Finance, our 100% owned finance subsidiary, issued $500.0 million in aggregate principal amount of 3.50% senior notes due 2021, $700.0 million in aggregate principal amount of 3.90% senior notes due 2024, and $400.0 million in aggregate principal amount of 4.90% senior notes due 2044 (collectively, the "2014 Bonds"). • The 2014 Bonds are fully and unconditionally guaranteed on a senior unsecured basis by Perrigo Company 82 Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources plc, and no other subsidiary of Perrigo Company plc guarantees the 2014 Bonds. We may redeem the 2014 Bonds at any time under the terms of the applicable indenture, subject to the payment of a make-whole premium. • On December 5, 2014, Perrigo Finance entered into a term loan agreement consisting of a €500.0 million ($614.3 million) tranche, with the ability to draw an additional €300.0 million ($368.6 million) tranche, maturing December 5, 2019, and we entered into a $300.0 million term loan tranche maturing December 18, 2015, which we repaid in full on June 25, 2015. • On December 5, 2014, we repaid the remaining $895.0 million outstanding under our 2013 Term Loan described below, then terminated it. • On June 24, 2015, we repaid the $300.0 million portion of the 2014 Term Loan. • On March 30, 2015, we assumed $20.0 million in aggregate principal amount of 6.19% senior notes due 2016 (the "2016 Notes"), €135.0 million ($147.0 million) aggregate principal amount of 5.1045% senior notes due 2023, €300.0 million ($326.7 million) in aggregate principal amount of 5.125% retail bonds due 2017, €180.0 million ($196.0 million) in aggregate principal amount of 4.500% retail bonds due 2017, and €120.0 million ($130.7 million) in aggregate principal amount of 5.000% retail bonds due 2019 (collectively, the "Retail Bonds") in connection with the Omega acquisition. • The fair value of the 2023 Notes and Retail Bonds exceeded par value by €93.6 million ($101.9 million) on the date of the acquisition. As a result, a fair value adjustment was recorded as part of the carrying value of the underlying debt and will be amortized as a reduction of interest expense over the remaining terms of the respective debt instruments. The adjustment does not affect cash interest payments. • On May 29, 2015, we repaid the $20.0 million in aggregate principal amount of the 2016 Notes. Debt Repayments and Related Extinguishment During the Year Ended December 31, 2017 During the year ended December 31, 2017, we reduced our outstanding debt through a variety of transactions (in millions): Series Transaction Type Principal Retired Date April 1, 2017 May 8, 2017 May 23, 2017 June 15, 2017 June 15, 2017 June 15, 2017 June 15, 2017 June 15, 2017 July 1, 2017 2014 term loan due December 5, 2019 Scheduled quarterly payment $ $600.0 2.300% senior notes due 2018 Early redemption €180.0 4.500% retail bonds due 2017 Scheduled maturity $500.0 3.500% senior notes due 2021 $500.0 3.500% senior notes due 2021 $800.0 4.000% senior notes due 2023 $400.0 5.300% senior notes due 2043 $400.0 4.900% senior notes due 2044 Tender offer Tender offer Tender offer Tender offer Tender offer 2014 term loan due December 5, 2019 Scheduled quarterly payment September 30, 2017 2014 term loan due December 5, 2019 Scheduled quarterly payment December 12, 2017 €300.0 5.125% senior notes due 2017 Scheduled maturity December 31, 2017 2014 term loan due December 5, 2019 Scheduled quarterly payment 13.3 600.0 201.3 190.4 219.6 584.4 309.5 96.1 14.3 14.8 352.3 15.0 $ 2,611.0 83 As a result of the of the early redemption and tender offer transactions discussed above, we recorded a loss of $135.2 million during the three months ended July 1, 2017 in Loss on extinguishment of debt (in millions): Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources Premium on debt repayment Transaction costs Write-off of deferred financing fees Write-off of remaining discount on bond $ 116.1 3.8 10.6 4.7 Total loss on extinguishment of debt $ 135.2 We entered into amendments on March 16, 2017 related to the 2014 Revolver and the 2014 Term Loan providing for additional time to deliver certain financial statements, as well as the modification of certain financial and other covenants. We also entered into additional amendments to the 2014 Revolver and the 2014 Term Loan on April 25, 2017 to modify provisions of such agreements necessary as a result of the correction in accounting related to the Tysabri® financial asset, as well as waivers of any default or event of default that may arise from any restatement of or deficiencies in our financial statements for the periods specified in such amendments and waivers. No default or event of default existed prior to entering into these amendments and waivers. We are in compliance with all covenants under our debt agreements as of December 31, 2017. See Item 1. Note 10 for more information on all of the above debt facilities. Credit Ratings Our credit ratings on December 31, 2017 were Baa3 (stable) and BBB- (stable) by Moody's Investors Service and Standard and Poor's Rating Services, respectively. Credit rating agencies review their ratings periodically and, therefore, the credit rating assigned to us by each agency may be subject to revision at any time. Accordingly, we are not able to predict whether current credit ratings will remain as disclosed above. Factors that can affect our credit ratings include changes in operating performance, the economic environment, our financial position, and changes in business strategy. If changes in our credit ratings were to occur, they could impact, among other things, future borrowing costs, access to capital markets, and vendor financing terms. Contractual Obligations Our enforceable and legally binding obligations as of December 31, 2017 are set forth in the following table. Some of the amounts included in this table are based on management’s estimates and assumptions about these obligations, including the duration, the possibility of renewal, anticipated actions by third parties and other factors. Because these estimates and assumptions are necessarily subjective, the enforceable and legally binding obligations actually paid in future periods may vary from the amounts reflected in the table (in millions). 2018 2019-2020 2021-2022 After 2022 Total Payment Due Short and long-term debt (1) $ 198.3 $ 746.9 $ 791.9 $ 2,767.8 $ 4,504.9 Capital lease obligations Purchase obligations (2) Operating leases (3) Other contractual liabilities reflected on the consolidated balance sheets: Deferred compensation and benefits (4) Other (5) Total 0.8 757.2 38.1 — 90.0 1,084.4 $ $ 1.4 13.7 56.2 — 6.6 824.8 $ — 0.1 32.3 — 4.9 829.2 — — 16.6 92.1 1.5 2,878.0 $ $ 2.2 771.0 143.2 92.1 103.0 5,616.4 (1) Short-term and long-term debt includes interest payments, which were calculated using the effective interest rate at December 31, 2017. (2) Consists of commitments for both materials and services. 84 Perrigo Company plc - Item 7 Financial Condition, Liquidity and Capital Resources (3) Used in normal course of business, principally for warehouse facilities and computer equipment. (4) Includes amounts associated with non-qualified plans related to deferred compensation, executive retention and post employment benefits. Of this amount, we have funded $34.6 million, which is recorded in Other non-current assets on the balance sheet. These amounts are assumed payable after five years, although certain circumstances, such as termination, would require earlier payment. (5) Primarily includes consulting fees, legal settlements, contingent consideration obligations, restructuring accruals, insurance obligations, and electrical and gas purchase contracts, which were accrued in Other current liabilities and Other non-current liabilities at December 31, 2017 for all years. We fund our U.S. qualified profit-sharing and investment plan in accordance with the Employee Retirement Income Security Act of 1974 regulations for the minimum annual required contribution and Internal Revenue Service regulations for the maximum annual allowable tax deduction. We are committed to making the required minimum contributions, which we expect to be approximately $25.9 million over the next 12 months. Future contributions are dependent upon various factors, including employees’ eligible compensation, plan participation and changes, if any, to current funding requirements. Therefore, no amounts were included in the Contractual Obligations table above. We generally expect to fund all future contributions with cash flows from operating activities. As of December 31, 2017, we had approximately $501.7 million of liabilities for uncertain tax positions. These unrecognized tax benefits have been excluded from the Contractual Obligations table above due to uncertainty as to the amounts and timing of settlement with taxing authorities. Net deferred income tax liabilities were $311.5 million as of December 31, 2017. This amount is not included in the Contractual Obligations table above because we believe this presentation would not be meaningful. Net deferred income tax liabilities are calculated based on temporary differences between the tax basis of assets and liabilities and their book basis, which will result in taxable amounts in future years when the book basis is settled. The results of these calculations do not have a direct connection with the amount of cash taxes to be paid in any future periods. As a result, scheduling net deferred income tax liabilities as payments due by period could be misleading because this scheduling would not relate to liquidity needs. Critical Accounting Estimates The determination of certain amounts in our financial statements requires the use of estimates. These estimates are based upon our historical experiences combined with management’s understanding of current facts and circumstances. Although the estimates are considered reasonable based on the currently available information, actual results could differ from the estimates we have used. Management considers the below accounting estimates to require the most judgment and to be the most critical in the preparation of our financial statements. These estimates are reviewed by the Audit Committee. Customer-Related Accruals and Allowances We generally record revenues from product sales when the goods are shipped to the customer. For customers with Free on Board ("FOB") destination terms, a provision is recorded to exclude shipments estimated to be in-transit to these customers at the end of the reporting period. A sales allowance is recorded and accounts receivable are reduced as revenues are recognized for estimated losses on credit sales due to customer claims for discounts, price discrepancies, returned goods, and other items. Revenue is also reduced for any contractual customer program arrangements and related liabilities are recorded concurrently. We maintain customer-related accruals and allowances that consist primarily of chargebacks, rebates, sales returns, shelf stock allowances, administrative fees, and other incentive programs. Some of these adjustments relate specifically to the RX segment while others relate to the CHCA and CHCI segments. The aggregate gross-to-net adjustments related to RX products can exceed 50% of the segment's gross sales. In contrast, the aggregate gross-to-net adjustments related to CHCA and CHCI typically do not exceed 10% of the segment's gross sales. Certain of these accruals and allowances are recorded on the balance sheet as current liabilities, and others are recorded as a reduction in accounts receivable. 85 Perrigo Company plc - Item 7 Critical Accounting Estimates Chargebacks We market and sell products directly to wholesalers, distributors, warehousing pharmacy chains, and other direct purchasing groups. We also market products indirectly to independent pharmacies, non-warehousing chains, managed care organizations, and group purchasing organizations, collectively referred to as ("indirect customers"). In addition, we enter into agreements with some indirect customers to establish contract pricing for certain products. These indirect customers then independently select a wholesaler from which to purchase the products at these contracted prices. Alternatively, we may pre-authorize wholesalers to offer specified contract pricing to other indirect customers. Under either arrangement, we provide chargeback credit to the wholesaler for any difference between the contracted price with the indirect customer and the wholesaler's invoice price. The accrual for chargebacks is based on historical chargeback experience and confirmed wholesaler inventory levels, as well as estimated sell- through levels by wholesalers to retailers. We regularly assess current pricing dynamics and wholesaler inventory levels to ensure the liability for future chargebacks is fairly stated. Medicaid Rebates We participate in certain qualifying U.S. federal and state government programs whereby discounts and rebates are provided to participating government entities. Medicaid rebates are amounts owed based upon contractual agreements or legal requirements with public sector (Medicaid) benefit providers, after the final dispensing of the product by a pharmacy to a benefit plan participant. Medicaid reserves are based on expected payments, which are driven by patient usage, contract performance, and field inventory that will be subject to a Medicaid rebate. Medicaid rebates are typically billed up to 180 days after the product is shipped, but can be billed as many as 270 days after the quarter in which the product is dispensed to the Medicaid participant. As a result, our Medicaid rebate provision includes an estimate of outstanding claims for end-customer sales that occurred but for which the related claim has not been billed, and an estimate for future claims that will be made when inventory in the distribution channel is sold through to plan participants. Our calculation also requires other estimates, such as estimates of sales mix, to determine which sales are subject to rebates and the amount of such rebates. Our rebates are reviewed on a monthly basis against actual claims data to ensure the liability is fairly stated. Returns and Shelf Stock Allowances Consistent with industry practice, we maintain a return policy that allows our customers to return product within a specified period prior to and subsequent to the expiration date. Generally, product may be returned for a period beginning six months prior to its expiration date to up to one year after its expiration date. The majority of our product returns are the result of product dating, which falls within the range set by our policy, and are settled through the issuance of a credit to the customer. Our estimate of the provision for returns is based upon our historical experience with actual returns, which is applied to the level of sales for the period that corresponds to the period during which our customers may return product. The period is based on the shelf life of the products at the time of shipment. Additionally, when establishing our reserves, we consider factors such as levels of inventory in the distribution channel, product dating and expiration period, size and maturity of the market prior to a product launch, entrance into the market of additional competition, and changes in formulations. Shelf stock allowances are credits issued to reflect changes in the selling price of a product and are based upon estimates of the amount of product remaining in a customer's inventory at the time of the anticipated price change. In many cases, the customer is contractually entitled to such a credit. The allowances for shelf stock adjustments are based on specified terms with certain customers, estimated launch dates of competing products, and estimated changes in market price. RX Administrative Fees and Other Rebates Consistent with pharmaceutical industry practice, rebates or administrative fees are offered to certain wholesale customers, group purchasing organizations, and end-user customers. Settlement of rebates and fees generally may occur from one to 15 months from the date of sale. We provide a provision for rebates at the time of sale based on contracted rates and historical redemption rates. Assumptions used to establish the provision include level of wholesaler inventories, contract sales volumes, and average contract pricing. 86 Perrigo Company plc - Item 7 Critical Accounting Estimates CHCA and CHCI Rebates and Other Allowances In the CHCA and CHCI segments, we offer certain customers a volume incentive rebate if specific levels of product purchases are made during a specified period. The accrual for rebates is based on contractual agreements and estimated levels of purchasing. In addition, we have a reserve for product returns, primarily related to damaged and unsaleable products. We also have agreements with certain customers to cover promotional activities related to our products such as coupon programs, new store allowances, and product displays. The accrual for these activities is based on customer agreements and is established at the time product revenue is recognized. Allowances for customer-related programs are generally recorded at the time of sale based on the estimates and methodologies described above. We continually monitor product sales provisions and re-evaluate these estimates as additional information becomes available, which includes, among other things, an assessment of current market conditions, trade inventory levels, and customer product mix. We make adjustments to these provisions at the end of each reporting period to reflect any such updates to the relevant facts and circumstances. The following table summarizes the activity in our customer-related accrual and allowance accounts on the Consolidated Balance Sheets (in millions): Customer-Related Accruals and Allowances RX All Other Segments * Chargebacks Medicaid Rebates Returns and Shelf Stock Allowances Admin.

Revenue Recognition Revenues from service and royalty arrangements, including revenues from collaborative agreements, consist primarily of royalty payments, payments for research and development services, up-front fees and milestone payments. If an arrangement requires the delivery or performance of multiple deliverables or service elements, we determine whether the individual elements represent "separate units of accounting". If the separate elements meet the requirements, we recognize the revenue associated with each element separately and revenue is allocated among elements based on their relative selling prices. If the elements within a multiple deliverable arrangement are not considered separate units of accounting, the delivery of an individual element is considered not to have occurred if there are undelivered elements that are considered essential to the arrangement. To the extent such arrangements contain refund clauses triggered by non-performance or other adverse circumstances, revenue is not recognized until all contractual obligations are satisfied. Non-refundable up-front fees are deferred and amortized to revenue over the related performance period. We estimate the performance period based on the specific terms of each collaborative agreement. Revenue 87 Total 459.2 (3.2) 891.4 (858.0) 489.4 (7.5) 1,875.6 (1,873.2) 484.3 0.1 2,048.1 Perrigo Company plc - Item 7 Critical Accounting Estimates associated with research and development services is recognized on a proportional performance basis over the period that we perform the related activities under the terms of the agreement. Revenue resulting from the achievement of contingent milestone events stipulated in the agreements is recognized when the milestone is achieved. Milestones are based upon the occurrence of a substantive element specified in the contract. Inventory Reserves We maintain reserves for estimated obsolete or unmarketable inventory based on the difference between the cost of the inventory and its estimated market value. In estimating the reserves, management considers factors such as excess or slow-moving inventories, product expiration dating, products on quality hold, current and future customer demand, and market conditions. Changes in these conditions may result in additional reserves. Income Taxes Our tax rate is subject to adjustment over the balance of the year due to, among other things, income tax rate changes by governments; the jurisdictions in which our profits are determined to be earned and taxed; changes in the valuation of our deferred tax assets and liabilities; adjustments to estimated taxes upon finalization of various tax returns; adjustments to our interpretation of transfer pricing standards, changes in available tax credits, grants and other incentives; changes in stock-based compensation expense; changes in tax laws or the interpretation of such tax laws (for example, proposals for fundamental U.S. and international tax reform); changes in U.S. generally accepted accounting principles; expiration of or the inability to renew tax rulings or tax holiday incentives; and the repatriation of earnings with respect to which we have not previously provided taxes. Although we believe that our tax estimates are reasonable and that we prepare our tax filings in accordance with all applicable tax laws, the final determination with respect to any tax audit, and any related litigation, could be materially different from our estimates or from our historical income tax provisions and accruals. The results of an audit or litigation could have a material effect on operating results and/or cash flows in the periods for which that determination is made. In addition, future period earnings may be adversely impacted by litigation costs, settlements, penalties, and/or interest assessments. Legal Contingencies We are involved in product liability, patent, commercial, regulatory and other legal proceedings that arise in the normal course of business. We record a liability when a loss is considered probable and the amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range and no amount within that range is a better estimate, the minimum amount in the range is accrued. If a loss is not probable or a probable loss cannot be reasonably estimated, no liability is recorded. We have established reserves for certain of our legal matters (refer to Item 8. Note 16). We also separately record any insurance recoveries that are probable of occurring. Acquisition Accounting We account for acquired businesses using the acquisition method of accounting, which requires that assets acquired and liabilities assumed be recorded at fair value, with limited exceptions. Any excess of the purchase price over the fair value of the specifically identified net assets acquired is recorded as goodwill. Amounts allocated to acquired In Process Research and Development ("IPR&D") are recognized at fair value and initially characterized as indefinite-lived intangible assets, irrespective of whether the acquired IPR&D has an alternative future use. If the acquired net assets do not constitute a business, the transaction is accounted for as an asset acquisition and no goodwill is recognized. In an asset acquisition, acquired IPR&D with no alternative future use is charged to expense at the acquisition date. The judgments made by management in determining the estimated fair value assigned to each class of asset acquired and liability assumed can materially impact our results of operations. As part of the valuation procedures, we typically consult an independent advisor. There are several methods that can be used to determine fair value. We typically use an income approach for valuing our specifically identifiable intangible assets by employing either a relief from royalty or multi-period excess earnings methodology. The relief from royalty method assumes that, if the acquired company did not own the intangible asset or intellectual property, it would be willing to pay a royalty for its use. The benefit of ownership of the intellectual property is valued as the relief from the royalty 88 Perrigo Company plc - Item 7 Critical Accounting Estimates expense that would otherwise be incurred. Typically we use this method for valuing readily transferable intangible assets that have licensing appeal, such as trade names and trademarks and certain technology assets. The multi-period excess earnings approach starts with a forecast of the net cash flows expected to be generated by the asset over its estimated useful life. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. We typically use this method for valuing intangible assets such as developed product technology, customer relationships, product formulations, and IPR&D. Some of the more significant estimates and assumptions inherent in one or both of these income approaches include: • • • • • the amount and timing of projected future cash flows, adjusted for the probability of technical and marketing success; the amount and timing of projected costs to develop IPR&D into commercially viable products; the discount rate selected to measure the risks inherent in the future cash flows; the estimate of an appropriate market royalty rate; and an assessment of the asset's life cycle and the competitive trends impacting the asset, including consideration of any technical, legal, regulatory, or economic barriers to entry. We believe the fair values assigned to the assets acquired and liabilities assumed are based on reasonable assumptions; however, unanticipated events and circumstances may occur that may affect the accuracy and validity of such assumptions, estimates or actual results. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our Consolidated Statements of Operations. Determining the useful life of an intangible asset also requires judgment, as different types of intangible assets will have different useful lives and certain assets may even be considered to have indefinite useful lives. Useful life is the period over which the intangible asset is expected to contribute directly or indirectly to our future cash flows. We determine the useful lives of intangible assets based on a number of factors, such as legal, regulatory, or contractual provisions that may limit the useful life, and the effects of obsolescence, anticipated demand, existence or absence of competition, and other economic factors on useful life. Financial Assets We accounted for the Tysabri® royalty stream as a financial asset and elected to use the fair value option model. We made the election to account for the Tysabri® financial asset using the fair value option as we believed this method was most appropriate for an asset that did not have a par value, a stated interest stream, or a termination date. The change in estimated fair value from investments in royalty rights is presented on our Consolidated Statements of Operations under the caption, "Change in financial assets." We were entitled to quarterly payments of royalties on Tysabri® sales. We recorded our right to royalty payments from Biogen when earned and when collection was reasonably assured. We recorded the change in fair value of the Tysabri® financial asset in our financial statements each period. Critical estimates in determining the fair value are the underlying revenue assumptions of Tysabri® sales and the discount rates. The revenue assumptions were impacted by product demand and market growth assumptions, inventory target levels, product approval and pricing assumptions. Factors that could cause a change in estimates of future cash flows include a change in estimated market size, entry of a competitive product that would erode market share, manufacturing and approval of a biosimilar equivalent product, a change in pricing strategy or reimbursement coverage, a delay in obtaining regulatory approval, a change in dosage of the product, and a change in the number of treatments. 89 Perrigo Company plc - Item 7 Critical Accounting Estimates The Tysabri® financial asset acquired in 2013 as part of the Elan acquisition represented a single unit of accounting. The fair value of the financial asset acquired was determined by using a discounted cash flow analysis related to the expected future cash flows to be generated by the royalty stream from Biogen based on the royalty percentage payments of Tysabri® sales. The financial asset is classified as a Level 3 asset within the fair value hierarchy, as our valuation utilized significant unobservable inputs, including industry analyst estimates for global Tysabri® sales, probability weighted as to the timing and amount of future cash flows along with certain discount rate assumptions. Cash flow forecasts included the estimated effect and timing of future competition, considering patents in effect for Tysabri® through 2024 and contractual rights to receive cash flows into perpetuity. The discounted cash flows are based upon the expected royalty stream forecasted into perpetuity using a 20-year discrete period with a declining rate terminal value. The pre-tax discount rate utilized was 7.72% and 7.83% at December 31, 2015, and June 27, 2015, respectively. Significant judgment is required in selecting appropriate discount rates. At December 31, 2015, and June 27, 2015, we performed an evaluation to assess the discount rate and general market conditions potentially affecting the fair value of our Tysabri® financial asset. As of December 31, 2015, had this discount rate increased or decreased by 0.5%, the fair value of the asset would have increased by $270.0 million or decreased by $260.0 million, respectively. As of June 27, 2015, had this discount rate increased or decreased by 0.5%, the fair value of the asset would have decreased by $260.0 million or increased by $290.0 million, respectively. The estimated fair value of the asset is subject to variation should those cash flows vary significantly from those estimates. Quarterly, we assess the expected future cash flows and to the extent such payments are greater or less than initial estimates, or the timing of such payments is materially different than the original estimates, we will adjust the estimated fair value of the asset. As of December 31, 2015, if the expected royalty cash flows used in the estimation process had increased or decreased by 5.0%, the fair value of the asset would have increased by $270.0 million or decreased by $280.0 million, respectively. As of June 27, 2015, if the expected royalty cash flows used in the estimation process had increased or decreased by 5.0%, the fair value of the asset would have increased by $280.0 million or decreased by $280.0 million, respectively. In November 2016, we announced we were evaluating strategic alternatives for the Tysabri® financial asset. As of December 31, 2016, the financial asset was adjusted based on this strategic review and sale process, see discussion below for additional information on the sale. The following table summarizes the change in our Consolidated Balance Sheet for the Tysabri® financial asset, which includes our fair value adjustment that is a Level 3 measurement under ASC 820 and is included in our Consolidated Statement of Operations for the years ended December 31, 2017, and December 31, 2016, and the six months ended December 31, 2015 (in millions): Tysabri® financial asset Beginning balance Royalties earned Change in fair value Divestiture Ending balance Change in Financial Assets Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 $ $ 2,350.0 $ 5,310.0 $ — — (2,350.0) (351.8) (2,608.2) — 5,420.0 (167.3) 57.3 — — $ 2,350.0 $ 5,310.0 On March 27, 2017, we announced the completed divestment of our Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017. We elected to account for the contingent milestone payments using the fair value option method, and these were recorded at an estimated fair value of $134.5 million as of December 31, 2017. We chose the fair value option as we believe it will help investors understand the potential future cash flows we may receive associated with the two contingent milestones. 90 Perrigo Company plc - Item 7 Critical Accounting Estimates We valued the contingent milestone payments using a modified Black-Scholes Option Pricing Model ("BSOPM"). Key inputs in the BSOPM are the estimated volatility and rate of return of royalties on global net sales of Tysabri® that are received by Royalty Pharma over time until payment of the contingent milestone payments is completed. Volatility and the estimated fair value of the milestones have a positive relationship such that higher volatility translates to a higher estimated fair value of the contingent milestone payments. In the valuation of contingent milestone payments performed, we assumed volatility of 30.0% and a rate of return of 8.07% as of December 31, 2017. We assess volatility and rate of return inputs quarterly by analyzing certain market volatility benchmarks and the risk associated with Royalty Pharma achieving the underlying projected royalties. During the year ended December 31, 2017, the fair value of the Royalty Pharma contingent milestone payments decreased $42.0 million, as a result of the decrease in the estimated projected Tysabri® revenues due to the launch of Ocrevus® late in the first quarter of 2017. In addition, payment of the contingent milestone payments is dependent on global net sales of Tysabri®. Of the $134.5 million of estimated fair valued contingent milestone payments as of December 31, 2017, $79.7 million and $54.8 million relates to the 2018 and 2020 contingent milestone payments, respectively. If Tysabri® global net sales do not meet the prescribed threshold in 2018, we will write off the $79.7 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $250 million and recognize income of $170.3 million in Change in financial assets on the Consolidated Statement of Operations. If Tysabri® global net sales do not meet the prescribed threshold in 2020, we will write off the $54.8 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $400.0 million and recognize income of $345.2 million in Change in financial assets on the Consolidated Statement of Operations. Global Tysabri® net sales need to exceed $1.9 billion and $2.0 billion in 2018 and 2020, respectively in order for Royalty Pharma to receive the level of royalties needed to trigger the milestone payments owed to us. Tysabri® net sales are anticipated to decline on a global basis in 2018, compared to 2017, due to increased competition from Ocrevus®, offset by volume growth in Tysabri® international markets (refer to Item 8. Note 6). The table below presents a reconciliation for the Royalty Pharma contingent milestone payments measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in millions). Change in fair value in the table was recorded in Change in financial assets on the Consolidated Statements of Operations. Royalty Pharma Contingent Milestone Payments Beginning balance Additions Payments Change in fair value Ending balance Year Ended December 31, 2017 $ $ — 184.5 (8.0) (42.0) 134.5 Goodwill and Indefinite-Lived Intangible Assets Goodwill represents amounts paid for an acquisition in excess of the fair value of net assets received. We test goodwill for impairment annually, or more frequently if changes in circumstances or the occurrence of events suggest an impairment exists (refer to Item 8. Note 1). Effective in the year ended December 31, 2016, we changed our segment structure. We performed our annual goodwill testing as of October 1, 2017, the first day of the fourth quarter of the year ended December 31, 2017. The test for impairment requires us to make several estimates about fair value, most of which are based on projected future cash flows and market valuation multiples. The estimates associated with the goodwill impairment tests are considered critical due to the judgments required in determining fair value amounts, including projected future cash flows that include assumptions about future performance. The discount rates used in testing each of our reporting units’ goodwill for impairment as of our annual testing date in the fourth quarter of 2017 are based on the weighted average cost of capital determined for each of the Company’s reporting units and ranged from 7.5% to 13.5%. Perpetual growth rates for each reporting unit ranged from 2.0% to 3.0%. Changes in these estimates may result in the recognition of an impairment loss. 91 Perrigo Company plc - Item 7 Critical Accounting Estimates During our annual goodwill testing as of October 1, 2017, we determined the fair value of each of our reporting units exceeded their net book values. The fair values of the BCH, UK AUS, and Animal Health reporting units were each less than 25.0% higher than their respective net book values. As a result, these reporting units are inherently at a higher risk for future impairments if they experience deterioration in business performance or market multiples, or increases in discount rates. These reporting units had the following remaining goodwill balances as of December 31, 2017: Reporting Unit Goodwill Remaining in Reporting Unit BCH Animal Health UK AUS $ $ $ 1,026.0 178.9 53.1 Segment CHCI CHCA CHCI Fair Value in excess of Carrying Value 6.6% 23.6% 18.3% The discounted cash flow forecasts used for these reporting units in goodwill impairment testing include assumptions about future activity levels in the near term and longer-term. If growth in these reporting units is lower than expected, we may experience deterioration in our cash flow forecasts that may indicate goodwill in the reporting units may be impaired in future impairment tests. We continue to monitor the progress and assess the reporting units for potential impairment should impairment indicators arise, as applicable, and at least annually during our fourth quarter impairment testing. Management performed sensitivity analyses on the discounted cash flow valuations that were prepared to estimate the enterprise values of each reporting unit. Discount rates were increased and decreased by increments of 50 basis points, up to cumulative increases and decreases of 150 basis points. Perpetual revenue growth rates were increased and decreased by increments of 50 basis points, up to cumulative increases and decreases of 100 basis points. A summary of the sensitivity analysis results is provided below for the three reporting units for which estimated fair value was less than 25.0% higher than net book value. BCH A 50 basis point increase in the discount rate, a 100 basis point decrease in the perpetual revenue growth rate, or different combinations thereof, would indicate potential impairment for this reporting unit. Based on the sensitivity of the discount rate assumption on the BCH reporting unit analysis, any increase in the discount rate over the next twelve months could negatively impact the estimated fair value of this reporting unit and lead to a future impairment. Certain macroeconomic factors which are not controlled by the reporting unit, such as rising inflation or interest rates, could cause an increase in the discount rate to occur. Deterioration in BCH performance over the next twelve months, such as lower than expected revenues or profitability that has a sustained impact on future periods, could also represent potential indicators of impairment requiring further impairment analysis. Animal Health A 100 basis point increase in the discount rate combined with a 100 basis point decrease in the perpetual revenue growth rate, or a 150 basis point increase in the discount rate combined with 50 basis point decrease in the perpetual revenue growth rate, would indicate potential impairment of this reporting unit. If the expected results for this reporting unit are not achieved, potential indicators of impairment may result, requiring further analysis. During the fourth quarter of 2017, the Animal Health reporting unit had an indication of potential impairment resulting from the termination of a supply agreement. We prepared an impairment test as of December 31, 2017 and determined the fair value of the Animal Health reporting unit continued to exceed net book value, by 8.9%. The 8.9% margin was lower than the excess fair value over carrying value of 23.6% that was estimated as of October 1, 2017. Therefore, while no impairment was recorded in 2017, the supply agreement termination increased the risk of future impairment in this reporting unit. Based on our estimates of fair value and the reported carrying values as of December 31, 2017, a 100 basis point increase in the discount rate, or a 100 basis point decrease in the perpetual revenue growth rate, would indicate potential impairment of this reporting unit. If the expected results for this reporting unit are not achieved, additional indicators of impairment may result, requiring further analysis. 92 Perrigo Company plc - Item 7 Critical Accounting Estimates UK AUS A 150 basis point increase in the discount rate, or a 100 basis point increase in the discount rate combined with a 100 basis point decrease in the perpetual revenue growth rate, would indicate potential impairment of this reporting unit. If the expected results for this reporting unit are not achieved, potential indicators of impairment may result, requiring further analysis. The sensitivity analyses described above for BCH, UK AUS, and Animal Health, while a useful tool, should not be used as a sole predictor of impairment. A thorough analysis of all the facts and circumstances existing at that time would need to be performed to determine if recording an impairment loss was appropriate. Certain trade names, trademarks, brands, as well as IPR&D assets, are determined to have an indefinite useful life and are not subject to amortization. We review them for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that any individual asset might be impaired, and adjust the carrying value of the asset as necessary. IPR&D assets are initially recognized at fair value and classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. We recorded the following impairment charges on the Consolidated Statements of Operations (in millions): Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 Goodwill $ Indefinite-lived intangible assets $ IPR&D $ — $ — $ 12.7 $ 1,092.6 849.5 3.5 $ $ $ — 185.1 — As of December 31, 2017, the remaining goodwill and indefinite-lived asset balances are $4.2 billion and $90.3 million, respectively (refer to Item 8. Note 3 and Note 6 for additional information regarding goodwill and indefinite-lived intangible asset impairment testing results and assumptions used, respectively). Definite-Lived Intangible Assets Definite-lived intangible assets consist of a portfolio of developed product technology/formulation and product rights, distribution and license agreements, customer relationships, non-compete agreements, and certain trademarks, trade names, and brands. The assets are amortized on either a straight-line basis or proportionately to the benefits derived from those relationships or agreements. For intangible assets subject to amortization, an impairment analysis is performed whenever events or changes in circumstances indicate that the carrying amount of any individual asset may not be recoverable. The carrying amount of an intangible asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. An impairment loss is recognized if the carrying amount of the asset is not recoverable and its carrying amount exceeds its fair value. We recorded the following impairment charges on the Consolidated Statements of Operations (in millions): Year Ended December 31, 2017 December 31, 2016 Definite-lived Intangible assets $ 19.7 $ 665.5 To the extent we experience additional unanticipated competitive market entrants or major adverse macro- economic events, we may incur additional impairment losses (refer to Item 8. Note 3 and Note 6 for a more detailed discussion of the impaired definite-lived intangible assets and assumptions used, respectively). 93 Perrigo Company plc - Item 7 Critical Accounting Estimates Guaranteed Liabilities On November 21, 2017, we completed the sale of our Israel API business, which was previously classified as held-for-sale, to SK Capital (refer to Item 8. Note 2). As a result of the sale, we recognized a guarantee liability. Per the agreement, we will be reimbursed for tax receivables for tax years prior to closing and will need to reimburse SK Capital for the settlement of any uncertain tax liability positions for tax years prior to closing. In addition, after closing and going forward, the Israel API business, will be assessed by and liable to the Israel Tax Authority ("ITA") for any audit findings. We are no longer the primary obligor on the liabilities transferred to SK Capital on November 21, 2017, however, we have provided a guarantee on certain obligations that were recorded at a fair value of $13.8 million, with a maximum possible payout of $34.9 million. Recently Issued Accounting Standards See Item 8. Note 1 for information regarding recently issued accounting standards. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Foreign Exchange Risk We are a global company with operations throughout North America, Europe, Australia, Mexico, and Israel. We transact business in each location's local currency and in foreign currencies, thereby creating exposures to changes in exchange rates. Our largest exposure is the movement of the U.S. dollar relative to the euro, which has increased due to the Omega acquisition. In addition, our U.S. operations continue to expand their export business, primarily in Canada, China, and Europe, and are subject to fluctuations in the respective exchange rates relative to the U.S. dollar. A large portion of the sales of our Israeli operations is in foreign currencies, primarily U.S. dollars and euros, while these operations largely incur costs in their local currency. Further, a portion of Biogen's global sales of Tysabri® are denominated in local currencies creating exposures to changes in exchange rates relative to the U.S. dollar and thereby impacting the amount of U.S. dollar royalties necessary to achieve our contingent payment thresholds in 2018 and 2020. Due to different sales and cost structures, certain segments experience a negative impact and certain segments a positive impact as a result of changes in exchange rates. We estimate the translation effect of a ten percent devaluation of the U.S. dollar relative to the other foreign currencies in which we transact business would have increased operating income of our non-U.S. operating units by approximately $87.1 million for the year ended December 31, 2017. This sensitivity analysis has inherent limitations. The analysis disregards the possibility that rates of multiple foreign currencies will not always move in the same direction relative to the value of the U.S. dollar over time and does not account for foreign exchange derivatives that we utilize to mitigate fluctuations in exchange rates. In addition, we enter into certain purchase commitments for materials that, although denominated in U.S. dollars, are linked to foreign currency valuations. These commitments generally contain a range for which the price of materials may fluctuate over time given the value of a foreign currency. The translation of the assets and liabilities of our non-U.S. dollar denominated operations is made using local currency exchange rates as of the end of the year. Translation adjustments are not included in determining net income but are disclosed in Accumulated Other Comprehensive Income ("AOCI") within shareholders’ equity on the Consolidated Balance Sheets until a sale or substantially complete liquidation of the net investment in the subsidiary takes place. In certain markets, we could recognize a significant gain or loss related to unrealized cumulative translation adjustments if we were to exit the market and liquidate our net investment. As of December 31, 2017, cumulative net currency translation adjustments decreased shareholders’ equity by $260.6 million. We monitor and strive to manage risk related to foreign currency exchange rates. Exposures that cannot be naturally offset within a local entity to an immaterial amount are often hedged with foreign exchange derivatives or netted with offsetting exposures at other entities (refer to Item 8. Note 8 for further information regarding our derivative and hedging activities). We cannot predict future changes in foreign currency movements and fluctuations that could materially impact earnings. 94 Perrigo Company plc - Item 7A Interest Rate Risk We are exposed to interest rate changes primarily as a result of interest income earned on our investment of cash on hand and interest expense on borrowings used to finance acquisitions and other general corporate purposes. We have in the past, and may in the future, enter into certain derivative financial instruments related to the management of interest rate risk, when available on a cost-effective basis (refer to Item 8. Note 8 for further information regarding our derivative and hedging activities). These instruments are managed on a consolidated basis to efficiently net exposures and thus take advantage of any natural offsets. We do not use derivative financial instruments for speculative purposes. Gains and losses on hedging transactions are offset by gains and losses on the underlying exposures being hedged. 95 ITEM 8.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the years ended December 31, 2017 and 2016, the period from June 28, 2015 to December 31, 2015, and the fiscal year ended June 27, 2015, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 1, 2018 expressed an adverse opinion thereon. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2008.

Item 8 Note 1 NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General Information The Company Perrigo Company plc was incorporated under the laws of Ireland on June 28, 2013 and became the successor registrant of Perrigo Company, a Michigan corporation, on December 18, 2013 in connection with the acquisition of Elan Corporation, plc ("Elan"). Unless the context requires otherwise, the terms "Perrigo," the "Company," "we," "our," "us," and similar pronouns used herein refer to Perrigo Company plc, its subsidiaries, and all predecessors of Perrigo Company plc and its subsidiaries. We are a leading global healthcare company, delivering value to our customers and consumers by providing Quality Affordable Healthcare Products®. Founded in 1887 as a packager of home remedies, we have built a unique business model that is best described as the convergence of a fast-moving consumer goods company, a high-quality pharmaceutical manufacturing organization and a world-class supply chain network. We believe we are one of the world's largest manufacturers of over-the-counter (“OTC”) healthcare products and suppliers of infant formulas for the store brand market. We are a leading provider of branded OTC products throughout Europe, and also a leading producer of generic pharmaceutical topical products such as creams, lotions, and gels, as well as nasal sprays and injection ("extended topical") prescription drugs. We are headquartered in Ireland, and sell our products primarily in North America and Europe, as well as in other markets, including Australia, Israel and China. Basis of Presentation Our fiscal year previously consisted of a 52- or 53-week year ending on or around June 30 of each year with each quarter ending on the Saturday closest to each calendar quarter end. Beginning on January 1, 2016, we changed our fiscal year to begin on January 1 and end on December 31 of each year. As a result of our change in year end, this report on Form 10-K discloses the results of our operations for: • The twelve-month period from January 1, 2017 through December 31, 2017; • The twelve-month period from January 1, 2016 through December 31, 2016; • The six-month period from June 28, 2015 through December 31, 2015; • The twelve-month period from June 29, 2014 to June 27, 2015; and • The six-month period from June 29, 2014 through December 27, 2014. We cut off our quarterly accounting periods on the Saturday closest to the end of the calendar quarter, with the fourth quarter ending on December 31 of each year. Segment Reporting Our reporting segments are as follows: • Consumer Healthcare Americas ("CHCA"), comprises our U.S., Mexico and Canada consumer healthcare business (OTC, contract, infant formula and animal health categories). • Consumer Healthcare International ("CHCI"), comprises our branded consumer healthcare business primarily in Europe and our consumer focused businesses in the U.K., Australia, and Israel. This segment also includes our U.K. liquid licensed products business. • Prescription Pharmaceuticals ("RX"), comprises our U.S. Prescription Pharmaceuticals business. We also had two legacy operating segments, Specialty Sciences and Other, which contained our Tysabri® financial asset and Active Pharmaceuticals business ("API") businesses, respectively, which we divested (refer to Note 2 and Note 6). Following these divestitures, there were no substantial assets or operations left in either of these segments. Effective January 1, 2017, all expenses associated with our former Specialty Sciences segment 105 Perrigo Company plc - Item 8 Note 1 were moved to unallocated expenses. Our segments reflect the way in which our management makes operating decisions, allocates resources and manages the growth and profitability of the Company. Principles of Consolidation The consolidated financial statements include our accounts and accounts of all majority-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. Unconsolidated Variable Interest Entities We have research and development ("R&D") arrangements with certain biotechnology companies that we determined to be variable interest entities ("VIEs"). We did not consolidate the VIEs in our financial statements because we lack the power to direct the activities that most significantly impact their economic performance and thus are not considered the primary beneficiaries of these entities. These arrangements provide us with certain rights and obligations to purchase product candidates from the VIEs, dependent upon the outcome of the development activities. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions, which affect the reported earnings, financial position and various disclosures. Although the estimates are considered reasonable, actual results could differ from the estimates. Non-U.S. Operations We translate our non-U.S. dollar-denominated operations’ assets and liabilities denominated in foreign currencies into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded in the cumulative translation account, a component of Accumulated Other Comprehensive Income ("AOCI"). Gains or losses from foreign currency transactions are included in Other expense, net. Revenues We generally record revenues from product sales when the goods are shipped to the customer. For customers with Free on Board destination terms, a provision is recorded to exclude shipments estimated to be in- transit to these customers at the end of the reporting period. A sales allowance is recorded and accounts receivable are reduced as revenues are recognized for estimated losses on credit sales due to customer claims for discounts, price discrepancies, returned goods and other items. Revenue is also reduced for any contractual customer program arrangements and related liabilities are recorded concurrently. We maintain customer-related accruals and allowances that consist primarily of chargebacks, rebates, sales returns, shelf stock allowances, administrative fees and other incentive programs. Some of these adjustments relate specifically to the RX segment while others relate only to the CHCA and CHCI segments. Certain of these accruals and allowances are recorded in the balance sheet as current liabilities and others are recorded as a reduction in accounts receivable. Changes in these estimates and assumptions related to customer programs may result in additional accruals or allowances. Customer-related accruals and allowances were $512.3 million, $484.3 million, and $489.4 million at December 31, 2017, December 31, 2016, and December 31, 2015, respectively. Revenues from service and royalty arrangements, including revenues from collaborative agreements, consist primarily of royalty payments, payments for R&D services, up-front fees and milestone payments. If an arrangement requires the delivery or performance of multiple deliverables or service elements, we determine whether the individual elements represent separate units of accounting. If the separate elements represent separate units of accounting, we recognize the revenue associated with each element separately and revenue is allocated among elements based on their relative selling prices. If the elements within a multiple deliverable arrangement are 106 Perrigo Company plc - Item 8 Note 1 not considered separate units of accounting, the delivery of an individual element is considered not to have occurred if there are undelivered elements that are considered essential to the arrangement. To the extent such arrangements contain refund clauses triggered by non-performance or other adverse circumstances, revenue is not recognized until all contractual obligations are satisfied. Non-refundable up-front fees are deferred and amortized to revenue over the related performance period. We estimate the performance period based on the specific terms of each collaborative agreement. Revenue associated with R&D services is recognized on a proportional performance basis over the period that we perform the related activities under the terms of the agreement. Revenue resulting from the achievement of contingent milestone events stipulated in the agreements is recognized when the milestone is achieved. Milestones are based upon the occurrence of a substantive element specified in the contract. Shipping and handling costs billed to customers are included in net sales. Conversely, shipping and handling expenses we incur are included in cost of sales. Cash and Cash Equivalents Cash and cash equivalents consist primarily of demand deposits and other short-term investments with maturities of three months or less at the date of purchase. The carrying amount of cash and cash equivalents approximates its fair value. Accounts Receivable We maintain an allowance for doubtful accounts that reduces our receivables to amounts that are expected to be collected. In estimating the allowance, management considers factors such as current overall and industry- specific economic conditions, statutory requirements, historical and anticipated customer performance, historical experience with write-offs and the level of past-due amounts. Changes in these conditions may result in additional allowances. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. In addition, included in our accounts receivable balance is $84.4 million and $83.4 million related to our Tysabri® financial asset at December 31, 2016 and December 31, 2015, respectively, for amounts earned that have not yet been received. Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in first- out method. Costs include material and conversion costs. Inventory related to R&D is expensed at the point when it is determined the materials have no alternative future use. We maintain reserves for estimated obsolete or unmarketable inventory based on the difference between the cost of the inventory and its estimated net realizable value. In estimating the reserves, management considers factors such as excess or slow-moving inventories, product expiration dating, products on quality hold, current and future customer demand and market conditions. Changes in these conditions may result in additional reserves (refer to Note 5). Investments Available for Sale Investments We determine the appropriate classification of securities as held-to-maturity, available-for-sale, or trading. The classification depends on the purpose for which the financial assets were acquired. Marketable equity securities are classified as available-for-sale. These securities are carried at fair value with unrealized gains and losses included in AOCI. The assessment for impairment of marketable securities classified as available-for-sale is based on established financial methodologies, including quoted market prices for publicly traded securities. If we determine that a loss in the value of an investment is other than temporary, the investment is written down to its estimated fair value. Any such losses are recorded in Other expense, net (refer to Note 7). 107 Perrigo Company plc - Item 8 Note 1 Cost Method Investments Non-marketable equity securities are carried at cost, less any write down for impairments, and are adjusted for impairment based on methodologies, an assessment of the impact of general private equity market conditions, and discounted projected future cash flows. Non-marketable equity securities are recorded in Other non-current assets (refer to Note 7). Equity Method Investments The equity method of accounting is used for unconsolidated entities over which we have significant influence; generally this represents ownership interests of at least 20% and not more than 50%. Under the equity method of accounting, we record the investments at carrying value and adjust for a proportionate share of the profits and losses of these entities each period. We evaluate our equity method investments for recoverability. If we determine that a loss in the value of an investment is other than temporary, the investment is written down to its estimated fair value. Any such losses are recorded in Other expense, net. Evaluations of recoverability are based primarily on projected cash flows. Due to uncertainties in the estimation process, actual results could differ from such estimates. Equity method investments are recorded in Other non-current assets (refer to Note 7). Derivative Instruments We record derivative instruments on the balance sheet on a gross basis as either an asset or liability measured at fair value (refer to Note 8). Additionally, changes in a derivative's fair value, which are measured at the end of each period, are recognized in earnings unless specific hedge accounting criteria are met. If hedge accounting criteria are met for cash flow hedges, the changes in a derivative’s fair value are recorded in shareholders’ equity as a component of other comprehensive income ("OCI"), net of tax. These deferred gains and losses are recognized in income in the period in which the hedged item and hedging instrument affect earnings. Any ineffective portion of the change in fair value is immediately recognized in earnings. We are exposed to credit loss in the event of nonperformance by the counterparties on derivative contracts. It is our policy to manage our credit risk on these transactions by dealing only with financial institutions having a long-term credit rating of "A" or better and by distributing the contracts among several financial institutions to diversify credit concentration risk. Should a counterparty default, our maximum exposure to loss is the asset balance of the instrument. The maximum term of our forward currency exchange contracts is 18 months. Property, Plant and Equipment, net Property, plant and equipment, net are recorded at cost and are depreciated using the straight-line method. Useful lives for financial reporting range from 3 to 20 years for machinery and equipment and 10 to 45 years for buildings. Maintenance and repair costs are charged to earnings, while expenditures that increase asset lives are capitalized. Depreciation expense includes amortization of assets recorded under capital leases and totaled $95.2 million, $100.2 million, $53.8 million, and $84.3 million, for the years ended December 31, 2017 and December 31, 2016, the six months ended December 31, 2015, and the year ended June 27, 2015, respectively. We held the following property, plant and equipment, net (in millions): December 31, 2017 December 31, 2016 December 31, 2015 Land Buildings Machinery and equipment Gross property, plant and equipment Less accumulated depreciation $ 45.5 $ 45.0 $ 514.3 1,078.6 1,638.4 (805.3) 520.2 1,094.7 1,659.9 (789.8) Property, plant and equipment, net $ 833.1 $ 870.1 $ 47.5 508.2 1,103.3 1,659.0 (772.8) 886.2 108 Perrigo Company plc - Item 8 Note 1 Financial Assets Prior to its divestiture on March 27, 2017, we accounted for the Tysabri® royalty stream as a financial asset and have elected to use the fair value option model (refer to Note 6). We made the election to account for the Tysabri® financial asset using the fair value option as we believe this method is most appropriate for an asset that does not have a par value, a stated interest stream, or a termination date. The fair value of the Tysabri® financial asset is determined by using a discounted cash flow analysis related to the expected future cash flows to be received. This asset is classified as Level 3 assets within the fair value hierarchy, as our valuation estimates utilize significant unobservable inputs, including estimates as to the probability and timing of future sales of the related products. Critical estimates in determining the fair value are the underlying revenue assumptions of Tysabri® sales and the discount rates. The revenue assumptions are impacted by product demand and market growth assumptions, inventory target levels, product approval, currency movements and pricing assumptions. Factors that could cause a change in estimates of future cash flows include a change in estimated market size, entry of a competitive product that would erode market share, manufacturing and approval of a biosimilar equivalent product, a change in pricing strategy or reimbursement coverage, a delay in obtaining regulatory approval, a change in dosage of the product, or a change in the number of treatments. Goodwill and Intangible Assets Goodwill Goodwill represents amounts paid for an acquisition in excess of the fair value of net assets received. Goodwill is tested for impairment annually on the first day of our fourth quarter, or more frequently if changes in circumstances or the occurrence of events suggest an impairment exists. The test for impairment requires us to make several estimates about fair value, most of which are based on projected future cash flows and market valuation multiples. The estimates associated with the goodwill impairment tests are considered critical due to the judgments required in determining fair value amounts, including projected discounted future cash flows. Changes in these estimates may result in the recognition of an impairment loss. Our annual impairment tests were performed as of October 1, 2017, October 2, 2016, September 27, 2015, and March 29, 2015, for the years ended December 31, 2017 and December 31, 2016, the six months ended December 31, 2015, and the year ended June 27, 2015, respectively. Intangible Assets We have intangible assets that we have acquired through various business acquisitions and include trademarks, trade names and brands, in-process research and development ("IPR&D"), developed product technology/formulation and product rights, distribution and license agreements, customer relationships and distribution networks, and non-compete agreements. The assets are typically initially valued using one of the following valuation methods: • Relief from royalty method: This method assumes that if the acquired company did not own the intangible asset or intellectual property, it would be willing to pay a royalty for its use. The benefit of ownership of the intellectual property is valued as the relief from the royalty expense that would otherwise be incurred. We typically use this method for valuing readily transferable intangible assets that have licensing appeal, such as trade names and trademarks and certain technology assets. • Multi-period excess earnings method: This method starts with a forecast of the net cash flows expected to be generated by the asset over its estimated useful life. These cash flows are then adjusted to present value by applying an appropriate discount rate that reflects the risk factors associated with the cash flow streams. We typically use this method for valuing intangible assets such as developed product technology, customer relationships, product formulations and IPR&D. • Lost income method: This method estimates the fair value of an asset by comparing the value of the business, inclusive of the asset, to the hypothetical value of the same business excluding the asset. 109 Perrigo Company plc - Item 8 Note 1 Indefinite-lived intangible assets include IPR&D and certain trademarks, trade names, and brands. IPR&D assets are recognized at fair value and are classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. If the associated research and development is completed, the IPR&D asset becomes a definite-lived intangible asset and is amortized over the asset's assigned useful life. If it is abandoned, an impairment loss is recorded. We test indefinite-lived trademarks, trade names, and brands for impairment quarterly, or more frequently if changes in circumstances or the occurrence of events suggest impairment exists, by comparing the carrying value of the assets to their estimated fair values. An impairment loss is recognized if the carrying amount of the asset is not recoverable and its carrying amount exceeds its fair value. Definite-lived intangible assets consist of a portfolio of developed product technology/formulation and product rights, distribution and license agreements, customer relationships, non-compete agreements, and certain trademarks, trade names, and brands. The assets are amortized on either a straight-line basis or proportionately to the benefits derived from those relationships or agreements. Useful lives vary by asset type and are determined based on the period over which the intangible asset is expected to contribute directly or indirectly to our future cash flows. We also review all other long-lived assets that have finite lives and that are not held for sale for impairment when indicators of impairment are evident by comparing the carrying value of the assets to their estimated future undiscounted cash flows. See Note 3 for further information on our goodwill and intangible assets. Assets Held for Sale We classify assets as "held for sale" when management approves and commits to a formal plan of sale with the expectation the sale will be completed within one year. The net assets of the business held for sale are then recorded at the lower of their current carrying value and the fair market value, less costs to sell (refer to Note 9). Deferred Financing Fees We record deferred financing fees as a reduction of long-term debt. Share-Based Awards We measure and record compensation expense for all share-based awards based on estimated grant date fair values, and net of any estimated forfeitures over the vesting period of the awards. Forfeiture rates are estimated at the grant date based on historical experience and adjusted in subsequent periods for any differences in actual forfeitures from those estimates. We estimate the fair value of stock option awards granted based on the Black-Scholes option pricing model, which requires the use of subjective and complex assumptions. These assumptions include estimating the expected term that awards granted are expected to be outstanding, the expected volatility of our stock price for a period commensurate with the expected term of the related options, and the risk-free rate with a maturity closest to the expected term of the related awards. Restricted stock and restricted stock units are valued based on our stock price on the day the awards are granted. The estimated fair value of outstanding Relative Total Shareholder Return performance units (“RTSR”) is based on the grant date fair value of RTSR awards using a Monte Carlo simulation, which includes estimating the movement of stock prices and the effects of volatility, interest rates, and dividends (refer to Note 12). Income Taxes We record deferred income tax assets and liabilities on the balance sheet as noncurrent based upon the difference between the financial reporting and the tax reporting basis of assets and liabilities using the enacted tax rates. To the extent that available evidence raises doubt about the realization of a deferred income tax asset, a valuation allowance is established. We have provided for income taxes for certain earnings of certain foreign subsidiaries which have not been 110 Perrigo Company plc - Item 8 Note 1 deemed to be permanently reinvested. For those foreign subsidiaries we have deemed to be permanently reinvested, we have provided no further tax provision. We record reserves for uncertain tax positions to the extent it is more likely than not that the tax position will be sustained on audit, based on the technical merits of the position. Periodic changes in reserves for uncertain tax positions are reflected in the provision for income taxes. We include interest and penalties attributable to uncertain tax positions and income taxes as a component of our income tax provision (refer to Note 14). Legal Contingencies We are involved in product liability, patent, commercial, regulatory and other legal proceedings that arise in the normal course of business. We record a liability when a loss is considered probable and the amount can be reasonably estimated. If the reasonable estimate of a probable loss is a range and no amount within that range is a better estimate, the minimum amount in the range is accrued. If a loss is not probable or a probable loss cannot be reasonably estimated, no liability is recorded. We have established reserves for certain of our legal matters (refer to Note 16). We also separately record any insurance recoveries that are probable of occurring. Research and Development All R&D costs, including payments related to products under development and research consulting agreements, are expensed as incurred. We may continue to make non-refundable payments to third parties for new technologies and for R&D work that has been completed. These payments may be expensed at the time of payment depending on the nature of the payment made. R&D expense was $167.7 million, $184.0 million, $88.2 million, and $187.8 million for the years ended December 31, 2017, and December 31, 2016, the six months ended December 31, 2015 and the year ended June 27, 2015, respectively. The year ended December 31, 2017 included R&D expense related to new product development and clinical trial expenses in our CHCA, CHCI and RX segments. The year ended December 31, 2016 included R&D expense related to clinical trials primarily in our CHCA and RX segments. The six months ended December 31, 2015 included incremental R&D expense attributable to the Omega Pharma Invest N.V. ("Omega") acquisition. The year ended June 27, 2015 included incremental R&D expense related to a collaboration agreement entered into as a result the Omega acquisition. We actively collaborate with other pharmaceutical companies to develop, manufacture and market certain products or groups of products. We may choose to enter into these types of agreements to, among other things, leverage our or others’ scientific research and development expertise or utilize our extensive marketing and distribution resources. Our policy on accounting for costs of strategic collaborations determines the timing of the recognition of certain development costs. In addition, this policy determines whether the cost is classified as development expense or capitalized as an asset. Management is required to form judgments with respect to the commercial status of such products in determining whether development costs meet the criteria for immediate expense or capitalization. For example, when we acquire certain products for which there is already an Abbreviated New Drug Application ("ANDA") or New Drug Application ("NDA") approval directly related to the product, and there is net realizable value based on projected sales for these products, we capitalize the amount paid as an intangible asset. If we acquire product rights that are in the development phase and as to which we have no assurance that the third party will successfully complete its development milestones, we expense the amount paid (refer to Note 17 for more information on our current collaboration agreements). 111 Perrigo Company plc - Item 8 Note 1 Advertising Costs We expense advertising costs as incurred. Advertising costs relate primarily to print advertising, direct mail, on-line advertising and social media communications. For the year ended December 31, 2017, 94% of advertising expense was attributable to our CHCI segment. Advertising costs were as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 145.3 $ 155.9 $ 77.5 $ 55.7 Earnings per Share ("EPS") Basic EPS is calculated using the weighted-average number of ordinary shares outstanding during each period. It excludes both the dilutive effects of additional common shares that would have been outstanding if the shares issued under stock incentive plans had been exercised and the dilutive effect of restricted shares and restricted share units, to the extent those shares and units have not vested. Diluted EPS is calculated including the effects of shares and potential shares issued under stock incentive plans, following the treasury stock method. Defined Benefit Plans We operate a number of defined benefit plans for employees globally. Two significant assumptions, the discount rate and the expected rate of return on plan assets, are important elements of expense and liability measurement. We evaluate these assumptions annually. Other assumptions involve employee demographic factors, such as retirement patterns, mortality, turnover, and the rate of compensation increase. The liability recognized in the balance sheet in respect of defined benefit pension plans is the present value of the defined benefit obligation at the balance sheet date less the fair value of plan assets. The defined benefit obligation is calculated periodically by independent actuaries using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows using interest rates of either high quality corporate bonds or long term government bonds depending on the depth and liquidity of the high quality corporate bond market in the different geographies where we have pension liabilities. The bonds are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. Actuarial gains and losses are recognized on the Consolidated Statement of Operations using the corridor method. Under the corridor method, to the extent that any cumulative unrecognized net actuarial gain or loss exceeds 10% of the greater of the present value of the defined benefit obligation and the fair value of the plan assets, that portion is recognized over the expected average remaining working lives of the plan participants. Otherwise, the net actuarial gain or loss is recorded in OCI. We recognize the funded status of benefit plans on the Consolidated Balance Sheets. In addition, we recognize the gains or losses and prior service costs or credits that arise during the period but are not recognized as components of net periodic pension cost of the period as a component of OCI (refer to Note 15). Recent Accounting Standard Pronouncements Below are recent accounting standard updates that we have adopted or are still assessing to determine the effect on our Consolidated Financial Statements. We do not believe that any other recently issued accounting standards could have a material effect on our Consolidated Financial Statements. As new accounting pronouncements are issued, we will adopt those that are applicable under the circumstances. 112 Recently Issued Accounting Standards Adopted Standard Clarifying the Definition of a Business Improvements to Employee Share-Based Payment Accounting Description This update clarifies the definition of a business and addresses whether transactions should be accounted for as asset acquisitions or business combinations (or divestitures). The guidance includes an initial threshold that an acquired set of assets will not be considered a business if substantially all of the fair value of the assets acquired is concentrated in a single tangible or identifiable intangible asset (or group of similar assets). If the acquired set does not pass the initial threshold, then the guidance requires that, to be a business, the set must include an input and a substantive process that together significantly contribute to the ability to create outputs. Different factors are considered to determine whether the set includes a substantive process, such as the inclusion of an organized workforce. Further, the guidance removes language stating that a business need not include all of the inputs and processes that the seller used in operating the business. This guidance is intended to simplify several aspects of the accounting for share-based payment award transactions. It will require all income tax effects of awards to be recorded through the income statement when the awards vest or settle as opposed to certain amounts being recorded in additional paid-in capital. An entity will also have to elect whether to account for forfeitures as they occur or by estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change (as currently required). The guidance will also increase the amount an employer can withhold to cover income taxes on awards. Perrigo Company plc - Item 8 Note 1 Date of adoption January 1, 2017 Effect on the Financial Statements or Other Significant Matters We early adopted this new standard and will apply it prospectively when determining whether transactions should be accounted for as asset acquisitions (divestitures) or business combinations (divestitures). During the year ended December 31, 2017, we applied the new guidance when determining whether certain product divestitures represented sales of assets or businesses. January 1, 2017 We adopted this standard as of January 1, 2017. We elected to estimate the number of awards expected to be forfeited and adjust the estimate when it is likely to change, consistent with past practice. We did not change the amounts that we withhold to cover income taxes on awards. As the requirement to record all income tax effects of vested or settled awards through the income statement is prospective in nature, there was no cumulative effect of adopting the standard on our balance sheet. 113 Perrigo Company plc - Item 8 Note 1 Effect on the Financial Statements or Other Significant Matters We have substantially completed our evaluation of the impact of adoption of the new revenue standard on our Consolidated Financial Statements. We will adopt the new revenue standard effective January 1, 2018 using the modified retrospective method. Upon adoption, we anticipate recognizing an adjustment of $5.4 million to the opening balance of retained earnings. The impact of adoption relates primarily to the new guidance on when revenue should be recognized, focusing on indicators of the customer gaining control. Under this new model, in certain cases revenue may be recognized over-time as opposed to a point in time. In our business, revenue may be recognized over-time for certain of our contract manufacturing and private label arrangements in which we produce products that do not have an alternative use, and if the contracts with customers were canceled, we would have an enforceable right to payment for performance completed to date, inclusive of a reasonable profit margin. As a result, we expect to recognize revenue earlier in the performance period for these arrangements as product is customized, as opposed to when units are shipped or delivered. Our assessment of the new revenue standard has also included, but has not been limited to, estimation of variable consideration and identification of performance obligations and we have determined that the related accounting is not materially different compared to our current practice. We have identified certain intra-entity asset transfers that will require an adjustment; based on our current analysis, no material adjustments have been identified at this time. January 1, 2018 We have identified certain investments that will require an adjustment; based on our current analysis, no material adjustments have been identified at this time. Recently Issued Accounting Standards Not Yet Adopted Standard Revenue from Contracts with Customers Effective Date January 1, 2018 Description The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: identify the contract(s) with a customer; identify the performance obligations in the contract; determine the transaction price; allocate the transaction price to the performance obligations in the contract; and recognize revenue when (or as) the entity satisfies a performance obligation. This guidance allows for two adoption methods, full retrospective approach or modified retrospective approach. January 1, 2018 Intra-Entity Asset Transfers of Assets Other Than Inventory Financial Instruments - Recognition and Measurement of Financial Assets and Liabilities Under the new guidance, the tax impact to the seller on the profit from the transfers and the buyer’s deferred tax benefit on the increased tax basis would be recognized when the transfers occur, resulting in the recognition of expense sooner than under historical guidance. The guidance excludes intra-entity transfers of inventory. For intra- entity transfers of inventory, the Financial Accounting Standards Board ("FASB") decided to retain current GAAP, which requires an entity to recognize the income tax consequences when the inventory has been sold to an outside party. The objective of this simplification update is to improve the decision usefulness of financial instrument reporting, and it principally affects accounting for equity investments currently classified as available for sale and financial liabilities where the fair value option has been elected. Entities will have to measure many equity investments at fair value and recognize changes in fair value in net income rather than other comprehensive income as required under current U.S. GAAP. 114 Perrigo Company plc - Item 8 Note 1 Effective Date January 1, 2019 Effect on the Financial Statements or Other Significant Matters We are currently evaluating the implications of adoption on our Consolidated Financial Statements. The actual impact will depend on our lease portfolio at the time of adoption. We have commenced the first step of identifying a task force to take the lead in implementing the new lease standard. January 1, 2019 We are currently evaluating the implications of adoption on our Consolidated Financial Statements. January 1, 2020 We are currently evaluating the new standard for potential impacts on our receivables, debt, and other financial instruments. January 1, 2020 We are currently evaluating the implications of adoption on our Consolidated Financial Statements. Recently Issued Accounting Standards Not Yet Adopted (continued) Standard Leases Derivatives and Hedging Measurement of Credit Losses on Financial Instruments Intangibles - Goodwill and Other Simplifying the Test for Goodwill Description This guidance was issued to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. For leases with a term of 12 months or less, lessees are permitted to make an election to not recognize right-of-use assets and lease liabilities. Upon adoption, lessees will apply the new standard as of the beginning of the earliest comparative period presented in the financial statements, however lessees will be able to exclude leases that expire as of the implementation date. Early adoption is permitted. This update was issued to enable entities to better portray the economics of their risk management activities in the financial statements and enhance the transparency and understandability of hedge results. In addition, the amendments simplify the application of hedge accounting in certain situations. Under the new rule, the entity’s ability to hedge non-financial and financial risk components is expanded. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and also eases certain documentation and assessment requirements. Early adoption is permitted. This guidance changes the impairment model for most financial assets and certain other instruments, replacing the current "incurred loss" approach with an "expected loss" credit impairment model, which will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, and off-balance sheet credit exposures such as letters of credit. Early adoption is permitted. The objective of this update is to reduce the cost and complexity of subsequent goodwill accounting by simplifying the impairment test by removing the Step 2 requirement to perform a hypothetical purchase price allocation when the carrying value of a reporting unit exceeds its fair value. If a reporting unit’s carrying value exceeds its fair value, an entity would record an impairment charge based on that difference, limited to the amount of goodwill attributed to that reporting unit. The proposal would not change the guidance on completing Step 1 of the goodwill impairment test. The proposed guidance would be applied prospectively. Early adoption is permitted. 115 Perrigo Company plc - Item 8 Note 2 NOTE 2 - ACQUISITIONS AND DIVESTITURES All of the below acquisitions, with the exception of the generic Benzaclin™ product purchase, have been accounted for under the acquisition method of accounting based on our analysis of the acquired inputs and processes, and the related assets acquired and liabilities assumed were recorded at fair value as of the acquisition date. Fair value estimates are based on a complex series of judgments about future events and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets and liabilities assumed, as well as asset lives, can materially impact our results of operations. The effects of all of the acquisitions described below were included in the Consolidated Financial Statements prospectively from the date of each acquisition. Unless otherwise indicated, acquisition costs incurred were immaterial and were recorded in Administration expense. Acquisitions Completed During the Year Ended December 31, 2016 Generic Benzaclin™ Product On August 2, 2016, we purchased the remaining 60.9% product rights to a generic Benzaclin™ product ("Generic Benzaclin™"), which we had developed and marketed in collaboration with Barr Laboratories, Inc. ("Barr"), a subsidiary of Teva Pharmaceuticals, for $62.0 million in cash. In September 2007, we entered into an initial development, marketing and commercialization agreement with Barr, in which Barr contributed to the product's development costs and we developed and marketed the product in the U.S. and Israel. Under this agreement, we paid Barr a percentage of net income from the product's sales in these territories, adjusted for Barr's contributions to the product's development costs. By purchasing the remaining product rights from Barr, we are now entitled to 100% of income from sales of the product. Operating results attributable to Generic Benzaclin™ are included within our RX segment. The intangible asset acquired is a distribution and license agreement with a nine- year useful life. Tretinoin Product Portfolio On January 22, 2016, we acquired a portfolio of generic dosage forms and strengths of Retin-A® (tretinoin), a topical prescription acne treatment, from Matawan Pharmaceuticals, LLC, for $416.4 million in cash ("Tretinoin Products"), which further expanded our standard topical products such as creams, lotions and gels, as well as inhalants and injections ("extended topicals") portfolio. We were the authorized generic distributor of these products from 2005 to 2013. Operating results attributable to the acquisition are included within our RX segment. The intangible assets acquired included generic product rights valued using the multi-period excess earnings method and assigned a 20-year useful life, and non-compete agreements valued using the lost income method and assigned a five-year useful life. The goodwill acquired is deductible for tax purposes. Development-Stage Rx Products In May 2015, we entered into an agreement with a clinical stage biotechnology company for two specialty pharmaceutical products in development ("Development-Stage Rx Products"). We paid $18.0 million for an option to acquire the two products, which was recorded in R&D expense. On March 1, 2016, to further invest in our specialty "prescription only" ("Rx") portfolio, we exercised the option for both products, which requires us to make contingent payments if we obtain regulatory approval and achieve certain sales milestones. We will also be obligated to make certain royalty payments over periods ranging from seven to ten years from the launch of each product. We accounted for the option exercise as a business acquisition within our RX segment, recording IPR&D and contingent consideration on the balance sheet. The IPR&D was valued using the multi-period excess earnings method and has an indefinite useful life until such time as the research is completed (at which time it will become a definite-lived intangible asset), or is determined to have no future use (at which time it would be impaired). The contingent consideration is an estimate of the future milestone payments and royalties based on probability- weighted outcomes, sensitivity analysis, and discount rates reflective of the risk involved. The amount of contingent consideration recognized was $24.9 million and was recorded in Other non-current liabilities. On December 20, 116 Perrigo Company plc - Item 8 Note 2 2017, we completed the sale of one of the Development-Stage Rx Products to an ophthalmic pharmaceutical company (see below for additional details on the divestiture). Purchase Price Allocation of Acquisitions Completed During the Year Ended December 31, 2016 The Tretinoin Products, Developed-Stage Rx Products, and four product acquisitions opening balance sheets are final.

Entocort® is a gastroenterology medicine for patients with mild to moderate Crohn's disease. The acquisition complemented our Rx portfolio. Operating results attributable to the acquisition are included within our RX segment. The intangible assets acquired included branded and authorized generic product rights with useful lives of 10 and 15 years, respectively, which were valued using the multi-period excess earnings method. During the year ended December 31, 2016, we recorded an impairment charge of $342.2 million (refer to Note 3). Naturwohl Pharma GmbH On September 15, 2015, we completed our acquisition of 100% of Naturwohl Pharma GmbH ("Naturwohl"), a Munich, Germany-based nutritional business known for its leading German dietary supplement brand, Yokebe®. The acquisition built on our CHCI segment's OTC product portfolio and European commercial infrastructure. The assets were purchased through an all-cash transaction valued at €133.5 million ($150.4 million). Operating results attributable to Naturwohl are included in the CHCI segment. The intangible assets acquired included a trademark with a 20-year useful life, customer relationships with a 15-year useful life, non-compete agreements with a three- year useful life, and a licensing agreement with a three-year useful life. We utilized the relief from royalty method for valuing the trademark, the multi-period excess earnings method for valuing the customer relationships, and the lost income method for valuing the non-compete agreements and the licensing agreement. The goodwill acquired is not deductible for tax purposes. ScarAway® On August 28, 2015, we completed our acquisition of ScarAway®, a leading U.S. OTC scar management brand portfolio comprised of five products, from Enaltus, LLC, for $26.7 million in cash. This acquisition served as our entry into the niche branded OTC business in the U.S. Operating results attributable to ScarAway® are included in the CHCA segment. The intangible assets acquired included a trademark with a 25-year useful life, non-compete agreements with a four-year useful life, developed product technology with an eight-year useful life, and customer relationships with a 15-year useful life. We utilized the relief from royalty method for valuing the trademark and developed product technology, the multi-period excess earnings method for valuing the customer relationships, and the lost income method for valuing the non-compete agreements. The goodwill acquired is deductible for tax purposes. GlaxoSmithKline Consumer Healthcare Product Portfolio On August 28, 2015, we completed our acquisition of a portfolio of well-established OTC brands from GlaxoSmithKline Consumer Healthcare (“GSK Products”). This acquisition further leveraged our European market share and expanded our product offerings. The assets were purchased through an all-cash transaction valued at €200.0 million ($223.6 million). Operating results attributable to the acquired GSK Products are included primarily in the CHCI segment. The intangible assets acquired included trademarks with a 20-year useful life and customer relationships with a 15-year useful life. We utilized the relief from royalty method for valuing the trademarks and the multi-period excess earnings method for valuing the customer relationships. The goodwill acquired is deductible for tax purposes. 118 Perrigo Company plc - Item 8 Note 2 Purchase Price Allocation of Acquisitions Completed During the Six Months Ended December 31, 2015 The Entocort®, Naturwohl, ScarAway®, GSK Products, and eight product development acquisitions opening balance sheets are final.The below table indicates the purchase price allocations for acquisitions completed during the six months ended December 31, 2015 (in millions): $ $ $ Purchase price paid Contingent consideration Total purchase consideration Assets acquired: Cash and cash equivalents Accounts receivable Inventories Goodwill Definite-lived intangibles: Distribution and license agreements, supply agreements Developed product technology, formulations, and product rights Customer relationships and distribution networks Trademarks, trade names, and brands Non-compete agreements Indefinite-lived intangibles: In-process research and development Total intangible assets Total assets Liabilities assumed: Accounts payable Accrued liabilities Net deferred income tax liabilities Total liabilities Net assets acquired Entocort® Naturwohl ScarAway® GSK Products All Other(1) 380.2 $ 150.4 $ 26.7 $ 223.6 $ — — — — 380.2 $ 150.4 $ 26.7 $ 223.6 $ 15.3 13.9 29.2 — $ — 0.2 — 4.6 3.3 1.5 61.0 $ — $ — $ — 1.0 3.5 — — 32.6 $ — $ 21.4 $ — $ — $ 380.0 — — — — 25.9 64.2 0.3 0.5 9.8 11.4 0.5 — 61.5 129.5 — $ $ $ $ $ $ — $ — $ 380.0 380.2 $ $ 111.8 182.2 — $ — — — $ 2.8 1.6 27.4 31.8 380.2 $ 150.4 $ $ $ $ $ — $ 22.2 26.7 $ $ — $ 191.0 223.6 $ $ — $ — $ — — — — — $ — $ 26.7 $ 223.6 $ 29.2 — — — — — — — — — 29.2 29.2 29.2 — — — — (1) Consists of eight product development acquisitions in our CHCA, CHCI and RX segments. Acquisitions Completed During the Year Ended June 27, 2015 Gelcaps Exportadora de Mexico, S.A. de C.V. On May 12, 2015, we completed our acquisition of 100% of Gelcaps Exportadora de Mexico, S.A. de C.V. ("Gelcaps"), the Mexican operations of Durham, North Carolina-based Patheon Inc., for $37.9 million in cash. The acquisition added softgel manufacturing technology to our supply chain capabilities and broadened our presence, product portfolio, and customer network in Mexico. Operating results attributable to Gelcaps are included in the CHCA segment. The intangible assets acquired included a trademark with a 25-year useful life and customer relationships with a 20-year useful life. We utilized the relief from royalty method for valuing the trademark and the multi-period excess earnings method for valuing the customer relationships. 119 Perrigo Company plc - Item 8 Note 2 Based on valuation estimates utilizing the comparative sales method, a step-up in the value of inventory of $0.6 million was recorded in the opening balance sheet, which was charged to cost of goods sold during the three months ended June 27, 2015. In addition, property, plant and equipment was written up by $0.9 million to its estimated fair market value based on a valuation method that included both the cost and market approaches. This additional step-up in value is being depreciated over the estimated remaining useful lives of the assets. The goodwill recorded is not deductible for tax purposes. Omega Pharma Invest N.V. On March 30, 2015, we completed our acquisition of Omega, a limited liability company incorporated under the laws of Belgium. Omega was a leading European OTC company and is providing us several key benefits, including advancing our growth strategy outside the U.S. by providing access across a larger global platform with critical mass in key European countries, establishing commercial infrastructure in the high barrier-to-entry European OTC marketplace, strengthening our product portfolio while enhancing scale and distribution, and expanding our international management presence. We purchased 95.77% of the issued and outstanding share capital of Omega (685,348,257 shares) from Alychlo N.V. (“Alychlo”) and Holdco I BE N.V. (together with Alychlo, the “Sellers”), limited liability companies incorporated under the laws of Belgium, under the terms of the Share Purchase Agreement dated November 6, 2014 (the "Share Purchase Agreement"). Omega holds the remaining 30,243,983 shares as treasury shares. The acquisition was a cash and stock transaction made up of the following consideration (in millions except per share data): Perrigo ordinary shares issued Perrigo per share price at transaction close on March 30, 2015 Total value of Perrigo ordinary shares issued Cash consideration Total consideration $ $ $ 5.4 167.64 904.9 2,078.3 2,983.2 The cash consideration shown in the above table was financed by a combination of debt and equity. We issued $1.6 billion of debt and issued 6.8 million ordinary shares, which raised $999.3 million, net of issuance costs (refer to Note 10). The Sellers agreed to indemnify us for certain potential future losses. The Sellers’ indemnification and other obligations to us under the Share Purchase Agreement are secured by up to €120.9 million ($127.2 million as of December 31, 2017) in cash that has been escrowed and 1.08 million of our ordinary shares, which are both being held in escrow to secure such obligations. Under the terms of the Share Purchase Agreement, Alychlo and its affiliates are subject to a three-year non-compete in Europe, and the Sellers are subject to a two-year non-solicit, in each case subject to certain exceptions. The Share Purchase Agreement contains other customary representations, warranties, and covenants of the parties, thereto. On December 16, 2016, we commenced an arbitral claim against the Sellers in connection with the Sellers' obligations to us under the Share Purchase Agreement. The fact of the claim has been made public, but the proceedings otherwise remain confidential. The Sellers deny liability (refer to Note 16 for additional information). The operating results attributable to Omega are included in the CHCI segment. We incurred general transaction costs (legal, banking and other professional fees), financing fees, and debt extinguishment charges in connection with the Omega acquisition. The amounts recorded were not allocated to a reporting segment. The table below details the acquisition costs, as well as losses on hedging activities associated with the acquisition purchase price, and where they were recorded (in millions): 120 Perrigo Company plc - Item 8 Note 2 Line item Administration Interest expense, net Other expense, net Loss on extinguishment of debt Total acquisition-related costs Year Ended June 27, 2015 $ $ 29.7 23.7 324.0 9.6 387.0 See Note 8 for further details on losses on the Omega-related hedging activities shown above in Other expense, net, and Note 10 for details on the loss on extinguishment of debt. We acquired the following intangible assets: indefinite-lived brands, a definite-lived trade name with an eight-year useful life, definite-lived brands with a 22-year useful life, a distribution network with a 21-year useful life, and developed product technology with useful lives ranging from four to 13 years. We also recorded goodwill, which is not deductible for tax purposes and represents the value we assigned to the expected synergies described above, in our CHCI segment. We utilized the multi-period excess earnings method to value the indefinite-lived brands, the definite-lived brands, and distribution network. We utilized the relief from royalty method to value the developed product technology and definite-lived trade name. The weighted-average useful life of all intangible assets acquired is 20.6 years (refer to Note 3 for further detail on Goodwill and Other Intangible Assets). Based on valuation estimates utilizing the comparative sales method, a step-up in the value of inventory of $15.1 million was recorded in the opening balance sheet and was charged to cost of goods sold during the three months ended June 27, 2015. In addition, property, plant and equipment were written up $41.5 million to their estimated fair market value based on a valuation method that included both the cost and market approaches. This additional step-up in value is being depreciated over the estimated remaining useful lives of the assets. Additionally, the fair value of the debt assumed on the date of acquisition exceeded par value by $101.9 million, which was recorded as part of the carrying value of the underlying debt and will be amortized as a reduction of interest expense over the remaining terms of the respective debt instruments (refer to Note 10 for more information on the debt we assumed from Omega and our subsequent payments on the debt). Lumara Health, Inc. On October 31, 2014, we acquired a portfolio of women's healthcare products from Lumara Health, Inc., ("Lumara") a privately-held, Chesterfield, Missouri-based specialty pharmaceutical company, for $83.0 million in cash. The acquisition of this portfolio further expanded our women's healthcare product offerings. Operating results attributable to the acquired Lumara products are included in the RX segment. The intangible assets acquired consisted of three product formulations with useful lives ranging from eight to 12 years. The assets were valued utilizing the multi-period excess earnings method. 121 Perrigo Company plc - Item 8 Note 2 Purchase Price Allocation of Acquisitions Completed During the Year Ended June 27, 2015 The Gelcaps, Omega, and Lumara opening balance sheets are final. Measurement period adjustments to the Gelcaps opening balance sheet were not material; there were no measurement period adjustments to the Lumara opening balance sheet. Measurement period adjustment made to the Omega opening balance sheet are shown below.

Valuation adjustments made during the measurement period resulted in a $10.2 million reduction of amortization expense (recorded primarily in Selling expense) for the six months ended December 31, 2015 that were related to the year ended June 27, 2015 (refer to Note 3 for further detail on Goodwill and Other Intangible Assets). 122 The below table indicates the purchase price allocation for acquisitions completed during the year ended June 27, 2015 (in millions): Perrigo Company plc - Item 8 Note 2 Total purchase consideration Assets acquired: Cash and cash equivalents Accounts receivable Inventories Prepaid expenses and other current assets Property, plant and equipment, net Goodwill Definite-lived intangibles: $ $ Gelcaps Omega Lumara 37.9 $ 2,983.2 $ 83.0 4.6 7.3 7.2 2.1 6.0 6.0 $ 14.7 $ 222.9 277.0 51.2 130.8 1,688.7 — 2.9 1.5 0.4 0.1 — Developed product technology, formulations, and product rights $ — $ 31.4 $ 82.0 Customer relationships and distribution networks Trademarks, trade names, and brands Indefinite-lived intangibles: Trademarks, trade names, and brands Total intangible assets Other non-current assets Total assets Liabilities assumed: Accounts payable Short-term debt Accrued liabilities Payroll and related taxes Accrued customer programs Long-term debt Net deferred income tax liabilities Other non-current liabilities Total liabilities Net assets acquired 6.6 — 4.4 1,056.3 287.5 2,003.8 11.0 $ 3,379.0 $ 0.4 2.4 44.6 $ 5,766.7 $ 3.3 $ 225.0 $ — 1.6 — — — 1.4 0.4 6.7 37.9 112.6 49.3 51.3 28.9 1,471.0 785.5 59.9 $ $ 2,783.5 2,983.2 $ $ — — — 82.0 — 86.9 — — 3.9 — — — — — 3.9 83.0 $ $ $ $ $ 123 Perrigo Company plc - Item 8 Note 2 Actual and Unaudited Pro Forma Impact of Acquisitions Our Consolidated Financial Statements include operating results from the Tretinoin Products, Entocort®, Naturwohl, GSK Products, ScarAway®, Omega, Gelcaps, and Lumara® acquisitions as well as from three small product acquisitions, from the date of each acquisition through December 31, 2017. Net sales and operating income attributable to the Tretinoin Products and two small product acquisitions included in our financial statements for the year ended December 31, 2016 totaled $85.3 million and $45.1 million, respectively. Net sales and operating income attributable to the Entocort®, Naturwohl, ScarAway®, and GSK acquisitions included in our financial statements for the six months ended December 31, 2015 totaled $51.0 million and $20.6 million, respectively.

The unaudited pro forma results do not reflect future events that have occurred or may occur after the acquisitions. Divestitures Completed During the Year Ended December 31, 2017 On January 3, 2017, we sold certain ANDAs for $15.0 million to a third party, which was recorded as a gain in Other operating income on the Consolidated Statements of Operations in our RX segment. On February 1, 2017, we completed the sale of the animal health pet treats plant fixed assets within our CHCA segment, which were previously classified as held-for sale. We received $7.7 million in proceeds, which resulted in an immaterial loss. On April 6, 2017, we completed the sale of our India API business to Strides Shasun Limited. We received $22.2 million of proceeds, inclusive of an estimated working capital adjustment, which resulted in an immaterial gain recorded in our Other segment. Prior to closing the sale, we determined that the carrying value of the India API business exceeded its fair value less the cost to sell, resulting in an impairment charge of $35.3 million, which was recorded in Impairment charges on the Consolidated Statements of Operations for the year ended December 31, 2016. 124 Perrigo Company plc - Item 8 Note 2 On August 25, 2017, we completed the sale of our Russian business, which was previously classified as held-for-sale, to Alvogen Pharma LLC. The total sale price was €12.7 million ($15.1 million), inclusive of an estimated working capital adjustment, which resulted in an immaterial gain recorded in our CHCI segment. Prior to closing the sale, we determined that the carrying value of the Russian business exceeded its fair value less the cost to sell, resulting in an impairment charge of $3.7 million, which was recorded in Impairment charges on the Consolidated Statements of Operations for the three months ended July 1, 2017. On November 21, 2017, we completed the sale of our Israel API business, which was previously classified as held-for-sale, to SK Capital for a sale price of $110.0 million, which resulted in an immaterial gain recorded in our Other segment in Other expense (Income), net on the Consolidated Statements of Operations. As a result of the sale, we recognized a guarantee liability (refer to Note 6). Per the agreement, we will be reimbursed for tax receivables for tax years prior to closing and will need to reimburse SK Capital for the settlement of any uncertain tax liability positions for tax years prior to closing. In addition, after closing and going forward, the Israel API business, will be assessed by and liable to the Israel Tax Authority ("ITA") for any audit findings. We are no longer the primary obligor on the liabilities transferred to SK Capital on November 21, 2017, however, we have provided a guarantee on certain obligations that were recorded at a fair value of $13.8 million, with a maximum possible payout of $34.9 million. On December 20, 2017, we completed the sale of one of the Development-Stage Rx Products to an ophthalmic pharmaceutical company. We will potentially receive the following consideration: (1) a milestone payment of $1.5 million after the buyer achieves net sales of $25.0 million in any given calendar year; (2) a milestone payment of $5.0 million after the buyer achieves $50.0 million in net sales in any given year; and (3) royalty payments of 2.5% of all net sales of the product from the date of the first commercial sales of the product and continuing until market entry of a generic equivalent of the product. Divestitures Completed During the Year Ended December 31, 2016 On August 5, 2016, we completed the sale of our U.S. Vitamins, Minerals, and Supplements ("VMS") business within our CHCA segment to International Vitamins Corporation ("IVC") for $61.8 million inclusive of an estimated working capital adjustment. Prior to closing the sale, we determined that the carrying value of the VMS business exceeded its fair value less the cost to sell, resulting in an impairment charge of $6.2 million, which was recorded in Impairment charges on the Consolidated Statements of Operations for the year ended December 31, 2016. 125 Perrigo Company plc - Item 8 Note 3 NOTE 3 - GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill Changes in the carrying amount of goodwill, by reportable segment, were as follows (in millions): Balance at June 27, 2015 $ 1,817.2 $ 1,530.2 $ 1,086.0 $ 199.6 $ 88.2 $ 4,721.2 CHCA CHCI RX Specialty Sciences Other Total Business acquisitions Changes in assets held-for-sale Currency translation adjustments Purchase accounting adjustments 9.7 (13.0) (0.8) 1.2 87.4 — (53.3) 418.9 — — (1.9) — — — — — Balance at December 31, 2015 1,814.3 1,983.2 1,084.1 199.6 Business acquisitions Changes in assets held-for-sale Impairments Currency translation adjustments Purchase accounting adjustments — 4.5 (24.5) (0.9) 17.2 — — (868.4) (27.5) (16.5) 1.7 — — 0.8 — Balance at December 31, 2016 1,810.6 1,070.8 1,086.6 Re-allocation of goodwill(1) Business divestitures Currency translation adjustments 35.3 — 1.5 — (4.1) 139.0 27.7 — 8.0 — — (199.6) — — — — — — — (14.6) (2.1) — 71.5 — 9.0 — 0.9 — 81.4 (63.0) (26.4) 8.0 97.1 (27.6) (58.1) 420.1 5,152.7 1.7 13.5 (1,092.5) (26.7) 0.7 4,049.4 — (30.5) 156.5 Balance at December 31, 2017 $ 1,847.4 $ 1,205.7 $ 1,122.3 $ — $ — $ 4,175.4 (1) Certain cash flow associated with the API business were retained. We performed a relative fair value allocation of the business retained and allocated it among the two segments where the business was allocated. The increase in goodwill in the year ended December 31, 2017 was due primarily to foreign currency translation adjustments. The decrease in goodwill for the year ended December 31, 2016 was due primarily to impairment charges recorded in the CHCI and Specialty Sciences segments as discussed below. The increase in goodwill in the six months ended December 31, 2015 was due primarily to purchase accounting adjustments to the Omega acquisition, as well as the Naturwohl and GSK acquisitions recorded in the CHCI segment (refer to Note 2). As required by our policy, we tested goodwill for impairment in the fourth quarter of 2017 (refer to Note 1). We determined the fair value of each of our reporting units exceeded their net book values. The fair values of the BCH, UK AUS and Animal Health reporting units were each less than 25.0% higher than their respective net book values as of the annual assessment date. As a result, these reporting units are inherently at a higher risk for future impairments if they experience deterioration in business performance or market multiples, or increases in discount rates. These reporting units had the following remaining goodwill balances as of December 31, 2017 (in millions): Reporting Unit Goodwill Remaining in Reporting Unit BCH Animal Health UK AUS $ $ $ 1,026.0 178.9 53.1 Segment CHCI CHCA CHCI Fair Value in excess of Carrying Value 6.6% 23.6% 18.3% Subsequently, at the end of the fourth quarter of 2017, the Animal Health reporting unit had an indication of potential impairment resulting from the termination of a supply agreement. We prepared an impairment test as of December 31, 2017 and determined the fair value of the Animal Health reporting unit continued to exceed net book value, by 8.9%. The 8.9% margin was lower than the excess fair value over carrying value of 23.6% that was estimated as of October 1, 2017. Therefore, while no impairment was recorded in 2017, the supply agreement termination increased the risk of future impairment in this reporting unit. 126 Perrigo Company plc - Item 8 Note 3 The discounted cash flow forecasts used for these reporting units in goodwill impairment testing include assumptions about future activity levels in both the near term and longer-term. If growth in these reporting units is lower than expected, we may experience deterioration in our cash flow forecasts that may indicate goodwill in the reporting units may be impaired in future impairment tests. We continue to monitor the progress and assess the reporting units for potential impairment should impairment indicators arise, as applicable, and at least annually during our fourth quarter impairment testing. During the year ended December 31, 2016, we identified indicators of goodwill impairment for certain of our reporting units, which required us to complete interim goodwill impairment testing (refer to Note 1 for our impairment process). Step one of the goodwill impairment test involves determining the fair value of the reporting unit using a discounted cash flow technique and comparing it to the reporting unit’s carrying value. The main assumptions supporting the cash flow projections used to determine the reporting units’ fair value include revenue growth based on product line extensions, product life cycle strategies, and geographical expansion within the markets in which the reporting unit distributes products, gross margins consistent with historical trends, and advertising and promotion investments largely consistent with the reporting unit's growth plans. If a reporting unit does not pass step one of the goodwill impairment test, step two is completed. The second step of the goodwill impairment test requires that we determine the implied fair value of the reporting unit’s goodwill, which involves determining the value of the reporting unit’s individual assets and liabilities. If the reporting unit’s carrying value exceeds its book value, an impairment charge is recorded. During the three months ended April 2, 2016, we identified indicators of impairment for our Branded Consumer Healthcare - Rest of World ("BCH-ROW") reporting unit, which comprises primarily operations attributable to the Omega acquisition in all geographic regions except for Belgium. The primary impairment indicators included the decline in our 2016 performance expectations and a reduction in our long-range revenue growth forecast. BCH-ROW did not pass step one of goodwill impairment testing. The change in fair value from previous estimates was due primarily to the changes in the market and performance of the brands such that the evaluation of brand prioritization and product extensions or launches in new regions are being more focused to maximize the potential of all brands in the segment's portfolio. Based on our evaluation and initial estimates of the fair values of the assets and liabilities and the deficit of the fair value when compared to the related book value, we recorded $130.5 million in impairment charges on the Consolidated Statement of Operations within our CHCI segment. During the three months ended October 1, 2016, we identified additional indicators of goodwill impairment in both our BCH-ROW and our Branded Consumer Healthcare - Belgium ("BCH-Belgium") reporting units. With respect to both reporting units, the primary impairment indicators included an additional decline in our 2016 performance expectations for the remainder of the year and a reduction in our long-range revenue growth and margin forecasts due to the factors outlined below. Neither the BCH-ROW nor the BCH-Belgium reporting units passed step one of goodwill impairment testing. As it relates to the BCH-ROW reporting unit, the changes in fair value from previous estimates were due primarily to (1) changes in the market and performance of certain brands due to moderated new product launch assumptions, (2) execution of certain key product strategies falling short of expectations causing a reduction to baseline forecast models in France, Germany and Italy and (3) certain macro-economic factors continuing to impact the business more than expected in France, Russia and Turkey in addition to unfavorable foreign currency impacts experienced (primarily in the UK related to Brexit.) As it relates to the BCH-Belgium reporting unit, the changes in fair value from previous estimates were due to changes in the forecasts as a result of a reduction in volume with a major wholesaler due to factors consistent with those outlined for the BCH-ROW reporting unit. Based on our estimates of the fair values of the assets and liabilities and the deficit of the fair value when compared to the related book value, we recorded an impairment charge of $675.6 million related to the BCH-ROW reporting unit and $62.3 million related to the BCH-Belgium reporting unit on the Consolidated Statement of Operations within our CHCI segment. During the three months ended December 31, 2016, we identified indicators of goodwill impairment in the BCH-Belgium reporting unit related to the early termination of a distribution agreement. We prepared a goodwill impairment test as of December 3, 2016, which was the end of the month in which the impairment indicator 127 Perrigo Company plc - Item 8 Note 3 occurred. Step one of the goodwill impairment test indicated that the fair value of the BCH-Belgium reporting unit as greater than its net book value. As a result, we did not perform the second step of the goodwill impairment test. During the three months ended December 31, 2016, we identified indicators of goodwill impairment in the Animal Health reporting unit related to changes in the market and performance of certain brands. We prepared a goodwill impairment test as of October 2, 2016 as part of our annual goodwill impairment testing process. Step one of the goodwill impairment test indicated that the fair value of the Animal Health reporting unit was below its net book value. As a result, we performed the second step of the goodwill impairment test to measure the amount of impairment. We concluded that Animal Health goodwill was impaired by $24.5 million, which we recorded in Impairment charges on the Consolidated Statement of Operations within our CHCA segment. During the three months ended December 31, 2016, we identified indicators of goodwill impairment in the Specialty Sciences reporting unit related to our decision to review strategic alternatives for the Tysabri® financial asset. As a result of the impairment indicators, we prepared a goodwill impairment test as of December 31, 2016. Step one of the goodwill impairment test indicated that the fair value of the Specialty Sciences reporting unit was below its net book value. As a result, we initiated the second step of the goodwill impairment test to measure the amount of impairment. We concluded that the goodwill was fully impaired and recorded an impairment of $199.6 million in Impairment charges on the Consolidated Statement of Operations within our Specialty Sciences segment. No impairment charges were recorded as a result of the annual goodwill impairment testing during the six months ended December 31, 2015. During the year ended June 27, 2015, we performed our annual goodwill impairment testing, which indicated that our CHCA Mexico reporting unit's goodwill fair value was below its net book value as of March 28, 2015. As a result, we initiated the second step of the goodwill impairment test to measure the amount of impairment. We concluded that the goodwill was fully impaired and recorded an impairment of $6.8 million in the CHCA segment during the year ended June 27, 2015 in Impairment charges. No other segments were affected by this impairment charge. Intangible Assets Other intangible assets and the related accumulated amortization consisted of the following (in millions): December 31, 2017 December 31, 2016 December 31, 2015 Gross Accumulated Amortization Gross Accumulated Amortization Gross Accumulated Amortization Definite-lived intangibles: Distribution and license agreements, supply agreements Developed product technology, formulations, and product rights Customer relationships and distribution networks Trademarks, trade names, and brands Non-compete agreements Total definite-lived intangibles Indefinite-lived intangibles: Trademarks, trade names, and brands In-process research and development Total indefinite-lived intangibles Total other intangible assets $ 311.2 $ 169.8 $ 305.6 $ 120.4 $ 242.4 $ 77.7 1,358.4 1,642.0 1,335.4 14.7 598.7 1,418.1 526.0 1,387.6 460.6 129.5 12.6 1,489.9 1,189.3 14.3 307.5 55.3 11.2 1,520.7 539.4 15.2 4,661.7 $ 1,371.2 $ 4,417.2 $ 1,020.4 $ 3,705.3 $ 52.1 38.2 90.3 4,752.0 $ $ $ — $ — 50.5 64.0 — $ 114.5 1,371.2 $ 4,531.7 $ $ $ — $ 1,868.1 $ — 48.2 — $ 1,916.3 1,020.4 $ 5,621.6 $ $ $ $ $ $ 426.0 193.0 22.8 12.7 732.2 — — — 732.2 Certain intangible assets are denominated in currencies other than the U.S. dollars; therefore, their gross and net carrying values are subject to foreign currency movements. The increase in gross amortizable intangible assets during the year ended December 31, 2017 was due primarily to foreign currency translation. The decrease in gross amortizable intangible assets during the year ended 128 December 31, 2016 was due to the reclassification of Omega indefinite-lived assets to definite-lived assets as described below, offset by current year impairments taken as described below. The increase during the six months ended December 31, 2015 was due to the Entocort®, GSK, Naturwohl, and ScarAway® acquisitions, offset partially by purchase price adjustments to the Omega intangible assets (refer to Note 2). Perrigo Company plc - Item 8 Note 3 Intangible asset impairments taken are as follows (in millions): Year Ended December 31, 2017 Definite- Lived Intangible IPR&D Indefinite- Lived Intangible 0.4 December 31, 2016 Definite- Lived Intangible $ — $ — $ 1.1 11.6 — 849.1 — — 321.4 342.2 2.0 CHCA CHCI RX Other $ $ — $ — 19.7 — Six Months Ended December 31, 2015 Indefinite- Lived Intangible IPR&D — $ 3.5 — — — 185.1 — — 19.7 $ 12.7 $ 849.5 $ 665.6 $ 3.5 $ 185.1 During the three months ended July 1, 2017, we identified impairment indicators for our Lumara Health, Inc. ("Lumara") product assets. The primary impairment indicators included the decline in our 2017 performance expectations and a reduction in our long-range revenue growth forecast. The assessment utilized the multi-period excess earnings method to determine fair value and resulted in an impairment charge of $18.5 million in Impairment charges on the Consolidated Statements of Operations within our RX segment, which represented the difference between the carrying amount of the intangible assets and their estimated fair value. During the three months ended April 2, 2016, we identified indicators of impairment associated with certain indefinite-lived intangible assets acquired in conjunction with the Omega acquisition. The primary impairment indicators included the decline in our 2016 performance expectations and a reduction in our long-range revenue growth forecast. The assessment utilized the excess earnings method to determine fair value and resulted in an impairment charge of $273.4 million in Impairment charges on the Consolidated Statements of Operations within our CHCI segment, which represented the difference between the carrying amount of the intangible assets and their estimated fair value. The change in fair value from previous estimates was due primarily to the changes in the market and performance of the brands such that the evaluation of brand prioritization and product extensions or launches in new regions are being more focused to maximize the potential of all brands in the segment's portfolio. The main assumptions supporting the fair value of these assets and cash flow projections included revenue growth based on product line extensions, product life cycle strategies, geographical expansion within the markets in which the CHCI segment distributes products, gross margins consistent with historical trends, and advertising and promotion investments largely consistent with the segment's growth plans. During the three months ended October 1, 2016, we identified additional indicators of impairment associated with certain indefinite-lived and definite-lived intangible brand category assets acquired in conjunction with the Omega acquisition. The primary impairment indicators are discussed above in goodwill. The assessment of the indefinite-lived assets utilized the excess earnings method to determine fair value and resulted in an impairment charge of $575.7 million. With regards to definite-lived assets, it was determined that the carrying value of one asset group was not recoverable based on an assessment of the undiscounted future cash flows expected to be generated by the asset group. Given this, the excess earnings method was utilized to determine fair value of the definite-lived asset and resulted in an impairment charge of $290.9 million. Both charges, which represented the difference between the carrying amount of the intangible assets and their estimated fair value, were recorded in Impairment charges on the Consolidated Statements of Operations within our CHCI segment. The main assumptions supporting the fair value of these assets and cash flow projections are included in the goodwill discussions above. During the three months ended December 31, 2016, we identified impairment indicators in our Entocort® product assets which related to the entrance of new market competition and resulting negative impacts on sales volume and pricing. Utilizing a multi-period excess earnings method, we determined that the Entocort® product 129 Perrigo Company plc - Item 8 Note 3 assets were impaired by $342.2 million. We recorded this impairment in Impairment charges on the Consolidated Statement of Operations within our RX segment. During the three months ended December 31, 2016, we identified impairment indicators in certain definite- lived intangible assets, including trademarks and trade names related to our Herron products that we originally acquired through the acquisition of Aspen. After determining the assets were impaired, we utilized the relief from royalty method to quantify the impairment, resulting in a $30.5 million impairment. We recorded these impairments in Impairment charges on the Consolidated Statement of Operations within our CHCI segment. During our impairment testing for the six months ended December 31, 2015, we identified an impairment of certain indefinite-lived intangible assets based on management’s expectations of the prospects for future revenues, profits, and cash flows associated with these assets. The indefinite-lived intangible assets were purchased in conjunction with the Omega acquisition and are included in the CHCI segment. The assessment utilized the excess earnings method to determine fair value and resulted in an impairment charge of $185.1 million, which represents the difference between the carrying amount of the intangible assets and their estimated fair value. The amount was recorded in Impairment charges on the Consolidated Statements of Operations within the CHCI segment. The primary assumptions supporting the fair value of these assets and cash flow projections assume modest revenue growth based on product line extensions, product life cycle strategies, and geographical expansion within the markets in which the CHCI segment currently distributes products, and gross margins and advertising and promotion investments largely consistent with historical trends. No material impairment charges were recorded as a result of the annual intangible asset impairment testing during the year ended June 27, 2015. We recorded an impairment charge of $12.7 million and $3.5 million on certain IPR&D assets during the years ended December 31, 2017 and December 31, 2016, respectively, due to changes in the projected development and regulatory timelines for various projects, we also recorded a decrease in the contingent consideration liability associated with certain IPR&D assets in Other operating income on the Consolidated Statements of Operations (refer to Note 6). In addition, due to reprioritization of certain brands in the CHCI segment and change in performance expectations for the cough/cold/allergy, anti-parasite, personal care, lifestyle, and natural health brands, we reclassified $364.5 million and $674.4 million of indefinite-lived assets to definite-lived assets with useful lives of 20 years, which we began amortizing during the second and third quarters of 2016, respectively. The remaining weighted-average useful life for our amortizable intangible assets by asset class at December 31, 2017 was as follows: Amortizable Intangible Asset Category Distribution and license agreements, supply agreements Developed product technology, formulations, and product rights Customer relationships and distribution networks Trademarks, trade names, and brands Non-compete agreements Remaining Weighted- Average Useful Life (Years) 7 12 17 20 2 We recorded amortization expense of $349.6 million, $356.8 million, $128.6 million, $174.5 million during the years ended December 31, 2017 and December 31, 2016, the six months ended December 31, 2015, and the year ended June 27, 2015, respectively. The amortization expense in the year ended December 31, 2017 remained relatively flat. The increase in amortization expense in the year ended December 31, 2016 was due primarily to the incremental amortization expense incurred on the definite-lived intangible assets acquired from the Omega, Entocort®, and Tretinoin Products acquisitions. In addition, we incurred additional amortization in 2016 due to the previously indefinite-lived Omega brands changing classification to definite-lived during the year. The increase in amortization expense in the six months ended December 31, 2015 was due primarily to definite-lived assets 130 acquired from Omega. The increase in amortization expense in the year ended June 27, 2015 was due primarily to the inclusion of one quarter of amortization expense related to the intangible assets acquired from Omega. Estimated future amortization expense includes the additional amortization related to recently acquired intangible assets subject to amortization. Our estimated future amortization expense is as follows (in millions): Perrigo Company plc - Item 8 Note 3 Year 2018 2019 2020 2021 2022 $ Amount 341.0 316.4 280.8 251.8 222.0 Thereafter 1,878.5 NOTE 4 - ACCOUNTS RECEIVABLE FACTORING We have accounts receivable factoring arrangements with non-related third-party financial institutions (the “Factors”). Pursuant to the terms of the arrangements, we sell to the Factors certain of our accounts receivable balances on a non-recourse basis for credit approved accounts. An administrative fee per invoice is charged on the gross amount of accounts receivables assigned to the Factors, and interest is calculated at the applicable EUR LIBOR rate plus a spread. The total amount factored on a non-recourse basis and excluded from accounts receivable was $27.5 million, $50.7 million, and $64.5 million at December 31, 2017, December 31, 2016 and December 31, 2015, respectively.

The following fair value hierarchy is used in selecting inputs, with the highest priority given to Level 1, as these are the most transparent or reliable. Level 1: Quoted prices for identical instruments in active markets. Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. Level 3: Valuations derived from valuation techniques in which one or more significant inputs are not observable. 131 The following tables summarize the valuation of our financial instruments carried at fair value by the above pricing categories (in millions): Perrigo Company plc - Item 8 Note 6 Measured at fair value on a recurring basis: Assets: Investment securities Foreign currency forward contracts Funds associated with Israeli severance liability Total level 2 assets Royalty Pharma contingent milestone payments Financial assets Total level 3 assets Liabilities: Interest rate swap agreements Foreign currency forward contracts Total level 2 liabilities Contingent consideration Measured at fair value on a non-recurring basis: Assets: Goodwill(1) Indefinite-lived intangible assets(2) Definite-lived intangible assets(3) Assets held for sale, net Total level 3 assets Fair Value Hierarchy December 31, 2017 December 31, 2016 December 31, 2015 Fair Value Level 1 Level 2 Level 2 Level 3 Level 3 Level 2 Level 2 Level 3 Level 3 Level 3 Level 3 Level 3 $ $ $ $ $ $ $ $ $ $ $ $ $ $ 17.0 6.3 16.3 22.6 134.5 — 38.2 3.8 15.9 19.7 $ $ $ — $ 2,350.0 134.5 $ 2,350.0 $ — $ — $ 3.8 3.8 22.0 $ $ 5.0 5.0 69.9 $ $ — $ 1,148.4 $ — 11.5 — 0.3 758.0 18.2 14.9 4.8 17.2 22.0 — 5,310.0 5,310.0 0.3 3.9 4.2 17.9 — 1,031.8 — 37.5 11.5 $ 1,924.9 $ 1,069.3 (1) As of December 31, 2016, goodwill with a carrying amount of $2.2 billion was written down to its implied fair value of $1.1 billion. (2) As of December 31, 2016, indefinite-lived intangible assets with a carrying amount of $0.7 million were written down to a fair value of $0.3 million. As of December 31, 2015, indefinite-lived intangible assets with a carrying amount of $1.2 billion were written down to a fair value of $1.0 billion. (3) As of December 31, 2017, definite-lived intangible assets with a carrying amount of $31.2 million were written down to a fair value of $11.5 million. As of December 31, 2016, definite-lived intangible assets with a carrying amount of $2.3 billion were written down to a fair value of $758.0 million. Included in this balance are indefinite-lived intangible assets with a fair value of $364.5 million and $674.2 million that were reclassified to definite-lived assets at April 3, 2016 and October 2, 2016, respectively. There were no transfers among Level 1, 2, and 3 during the years ended December 31, 2017, and December 31, 2016, or the six months ended December 31, 2015. Our policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period (refer to Note 7 for information on our investment securities and Note 8 for a discussion of derivatives). 132 Perrigo Company plc - Item 8 Note 6 Foreign Currency Forward Contracts The fair value of foreign currency forward contracts is determined using a market approach, which utilizes values for comparable derivative instruments. Funds Associated with Israel Severance Liability Israeli labor laws and agreements require us to pay benefits to employees dismissed or retiring under certain circumstances. Severance pay is calculated on the basis of the most recent employee salary levels and the length of employee service. Our Israeli subsidiaries also provide retirement bonuses to certain managerial employees. We make regular deposits to retirement funds and purchase insurance policies to partially fund these liabilities. The funds are determined using prices for recently traded financial instruments with similar underlying terms, as well as directly or indirectly observable inputs, such as interest rates and yield curves, that are observable at commonly quoted intervals. Financial Assets On December 18, 2013, we acquired Elan, which had a royalty agreement with Biogen Idec Inc. ("Biogen"), whereby Biogen conveyed the right to receive royalties that are typically payable on sales revenue generated by the sale, distribution or other use of the drug Tysabri®. Pursuant to the royalty agreement, we were entitled to royalty payments from Biogen based on its Tysabri® sales in all indications and geographies. We received royalties of 12% on worldwide Biogen sales of Tysabri® from December 18, 2013 through April 30, 2014. From May 1, 2014, we received royalties of 18% on annual worldwide Biogen sales of Tysabri® up to $2.0 billion and 25% on annual sales above $2.0 billion. Prior to its divestiture on March 27, 2017, we accounted for the Tysabri® royalty stream as a financial asset and elected to use the fair value option model. We made the election to account for the Tysabri® financial asset using the fair value option as we believed this method was most appropriate for an asset that did not have a par value, a stated interest stream, or a termination date. The financial asset acquired represented a single unit of accounting. The fair value of the financial asset acquired was determined by using a discounted cash flow analysis related to the expected probability weighted future cash flows to be generated by the royalty stream. The financial asset was classified as a Level 3 asset within the fair value hierarchy, as our valuation utilized significant unobservable inputs, including industry analyst estimates for global Tysabri® sales, probability weighted as to the timing and amount of future cash flows along with certain discount rate assumptions. Cash flow forecasts included the estimated effect and timing of future competition, considering patents in effect for Tysabri® through 2024 and contractual rights to receive cash flows into perpetuity. The discounted cash flows were based upon the expected royalty stream forecasted into perpetuity using a 20-year discrete period with a declining rate terminal value. The pre-tax discount rate utilized was 7.72% and 7.83% at December 31, 2015, and June 27, 2015, respectively. In the first quarter of 2016, a competitor's pipeline product, Ocrevus®, received breakthrough therapy designation from the U.S. Food and Drug Administration ("FDA"). Breakthrough therapy designation is granted when a drug is intended alone or in combination with one or more other drugs to treat a serious or life threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. In June 2016, the FDA granted priority review with a target action date in December 2016. A priority review is a designation when the FDA will direct overall attention and resources to the evaluation of applications for drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. The product was approved late in the first quarter of 2017. The product is expected to compete with Tysabri®, and we expected it to have a significant negative impact on the Tysabri® royalty stream. Industry analysts believe that, based on released clinical study information, Ocrevus® will compete favorably against Tysabri® in the relapsing, remitting multiple sclerosis market segment due to its high efficacy and convenient dosage form. 133 Perrigo Company plc - Item 8 Note 6 Given the new market information for Ocrevus®, we used industry analyst estimates to reduce our first ten year growth forecasts from an average growth of approximately 3.4% in the fourth calendar quarter of 2015 to an average decline of approximately minus 2.0% in the third and fourth calendar quarters of 2016. In November 2016, we announced we were evaluating strategic alternatives for the Tysabri® financial asset. As of December 31, 2016, the financial asset was adjusted based on the strategic review and sale process. These effects, combined with the change in discount rate each quarter, led to a reduction in fair value of $204.4 million, $910.8 million, $377.4 million and $1.1 billion in the first, second, third and fourth quarters of 2016, respectively. At December 31, 2015, and June 27, 2015, we performed an evaluation to assess the discount rate and general market conditions potentially affecting the fair value of our Tysabri® financial asset. As of December 31, 2015, had this discount rate increased or decreased by 0.5%, the fair value of the asset would have increased by $270.0 million or decreased by $260.0 million, respectively. As of June 27, 2015, had this discount rate increased or decreased by 0.5%, the fair value of the asset would have decreased by $260.0 million or increased by $290.0 million, respectively. The estimated fair value of the asset is subject to variation should those cash flows vary significantly from those estimates. Quarterly, we assess the expected future cash flows and to the extent such payments are greater or less than initial estimates, or the timing of such payments is materially different than the original estimates, we will adjust the estimated fair value of the asset. As of December 31, 2015, if the expected royalty cash flows used in the estimation process had increased or decreased by 5.0%, the fair value of the asset would have increased by $270.0 million or decreased by $280.0 million, respectively. As of June 27, 2015, if the expected royalty cash flows used in the estimation process had increased or decreased by 5.0%, the fair value of the asset would have increased by $280.0 million or decreased by $280.0 million, respectively. In November 2016, we announced we were evaluating strategic alternatives for the Tysabri® financial asset. As of December 31, 2016, the financial asset was adjusted based on this strategic review and sale process. On March 27, 2017, we announced the completed divestment of our Tysabri® financial asset to Royalty Pharma for up to $2.85 billion, consisting of $2.2 billion in cash and up to $250.0 million and $400.0 million in milestone payments if the royalties on global net sales of Tysabri® that are received by Royalty Pharma meet specific thresholds in 2018 and 2020, respectively. As a result of this transaction, we transferred the entire financial asset to Royalty Pharma and recorded a $17.1 million gain during the three months ended April 1, 2017. We elected to account for the contingent milestone payments using the fair value option method, and these were recorded at an estimated fair value of $134.5 million as of December 31, 2017. We chose the fair value option as we believe it will help investors understand the potential future cash flows we may receive associated with the two contingent milestones. The following table summarizes the change in our Consolidated Balance Sheet for the Tysabri® Financial Asset, which includes our fair value adjustment that is a Level 3 measurement under ASC 820 and is included in our Consolidated Statement of Operations for the years ended December 31, 2017 and December 31, 2016, six months ended December 31, 2015, and year ended June 27, 2015 (in millions): Tysabri® financial asset Beginning balance Royalties earned Change in fair value Divestitures Ending balance Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 Year Ended June 27, 2015 $ $ 2,350.0 $ 5,310.0 $ 5,420.0 $ — — (2,350.0) (351.8) (2,608.2) — (167.3) 57.3 — 5,680.0 (338.5) 78.5 — — $ 2,350.0 $ 5,310.0 $ 5,420.0 134 Perrigo Company plc - Item 8 Note 6 Royalty Pharma Contingent Milestone Payments We valued the contingent milestone payments using a modified Black-Scholes Option Pricing Model ("BSOPM"). Key inputs in the BSOPM are the estimated volatility and rate of return of royalties on global net sales of Tysabri® that are received by Royalty Pharma over time until payment of the contingent milestone payments is completed. Volatility and the estimated fair value of the milestones have a positive relationship such that higher volatility translates to a higher estimated fair value of the contingent milestone payments. In the valuation of contingent milestone payments performed, we assumed volatility of 30.0% and a rate of return of 8.07% as of December 31, 2017. We assess volatility and rate of return inputs quarterly by analyzing certain market volatility benchmarks and the risk associated with Royalty Pharma achieving the underlying projected royalties. During the year ended December 31, 2017, the fair value of the Royalty Pharma contingent milestone payments decreased $42.0 million, as a result of the decrease in the estimated projected Tysabri® revenues due to the launch of Ocrevus® late in the first quarter of 2017. In addition, payment of the contingent milestone payments is dependent on global net sales of Tysabri®. Of the $134.5 million of estimated fair valued contingent milestone payments as of December 31, 2017, $79.7 million and $54.8 million relates to the 2018 and 2020 contingent milestone payments, respectively. If Tysabri® global net sales do not meet the prescribed threshold in 2018, we will write off the $79.7 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $250 million and recognize income of $170.3 million in Change in financial assets on the Consolidated Statement of Operations. If Tysabri® global net sales do not meet the prescribed threshold in 2020, we will write off the $54.8 million asset as an expense to Change in financial assets on the Consolidated Statement of Operations. If the prescribed threshold is exceeded, we will write up the asset to $400.0 million and recognize income of $345.2 million in Change in financial assets on the Consolidated Statement of Operations. Global Tysabri® net sales need to exceed $1.9 billion and $2.0 billion in 2018 and 2020, respectively in order for Royalty Pharma to receive the level of royalties needed to trigger the milestone payments owed to us. See Note 1 for amounts recorded in our accounts receivable related to our Tysabri® financial asset. The table below presents a reconciliation for the Royalty Pharma contingent milestone payments measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in millions). Change in fair value in the table was recorded in Change in financial assets on the Consolidated Statements of Operations. Royalty Pharma Contingent Milestone Payments Beginning balance Additions Payments Change in fair value Ending balance Year Ended December 31, 2017 $ $ — 184.5 (8.0) (42.0) 134.5 Interest Rate Swaps The fair values of interest rate swaps are determined using a market approach, which utilizes values for comparable swap instruments. 135 Perrigo Company plc - Item 8 Note 6 Guarantee Liability Related to The Israel API Sale On November 21, 2017, we completed the sale of our Israel API business to SK Capital (refer to Item 8. Note 2). As a result of the sale, we recognized a guarantee liability, which was classified as a level 3 liability. Per the agreement, we will be reimbursed for tax receivables for tax years prior to closing and will need to reimburse SK Capital for the settlement of any uncertain tax liability positions for tax years prior to closing. In addition, after closing and going forward, the Israel API business, will be assessed by and liable to the Israel Tax Authority ("ITA") for any audit findings. As of November 21, 2017, we are no longer the primary obligor on the liabilities transferred to SK Capital, however, we have provided a guarantee on certain obligations that were recorded at a fair value of $13.8 million, with a maximum possible payout of $34.9 million. Contingent Consideration Contingent consideration represents milestone payment obligations obtained through product acquisitions, which are valued using estimates based on probability-weighted outcomes, sensitivity analysis, and discount rates reflective of the risk involved. The estimates are updated quarterly and the liabilities are adjusted to fair value depending on a number of assumptions, including the competitive landscape and regulatory approvals that may impact the future sales of a product. We reduced a contingent consideration liability associated with certain IPR&D assets (refer to Note 3) and recorded a corresponding gain of $17.4 million during the year ended December 31, 2017. The liability decrease relates to a reduction of the probability of achievement assumptions and anticipated cash flows (refer to Note 2). In addition, we sold a certain IPR&D asset and the corresponding contingent consideration of $12.5 million was reduced. Purchases or additions for the year ended December 31, 2016 included contingent consideration associated with five transactions. The table below presents a reconciliation for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) (in millions). Net realized losses in the table were recorded in Other expense (Income), net on the Consolidated Statements of Operations.

Goodwill and Indefinite-Lived Intangible Assets We have six reporting units for which we assess the goodwill in each reporting unit for impairment. We conduct our goodwill and indefinite-lived intangible asset impairment test on the first day of the fourth quarter, unless indications of impairment exists during an interim period. We utilize a comparable company market approach, weighted equally with a discounted cash flow analysis, to determine the fair value of the reporting units. We utilize either a relief from royalty method or a multi-period excess earnings method to value our indefinite-lived intangible assets. We use a consistent set of projected financial information for the goodwill and indefinite-lived asset impairment tests. The discounted cash flow analysis that we prepared for goodwill impairment testing purposes for the year ended December 31, 2017 included long-term growth rates ranging from of 2.0% to 3.0%. We 136 Perrigo Company plc - Item 8 Note 6 also utilized discount rates ranging from 7.5% to 13.5%, which were deemed to be commensurate with the required investment return and risk involved in realizing the projected free cash flows of each reporting unit. In addition, we burdened projected free cash flows with the capital spending deemed necessary to support the cash flows of each reporting unit, and applied the tax rates that were applicable to the jurisdictions represented within each reporting unit. We recorded Impairment charges on the Consolidated Statements of Operations related to Goodwill and indefinite lived intangible assets of $1.1 billion and $849.5 million, for the year ended December 31, 2016, respectively. We recorded Impairment charges on the Consolidated Statements of Operations related to indefinite- lived intangible assets of $185.1 million for the six months ended December 31, 2015. As of December 31, 2017, the remaining goodwill and indefinite-lived asset balances were $4.2 billion and $90.3 million, respectively (refer to Note 3). Definite-Lived Intangible Assets When assessing our definite-lived assets for impairment, we utilize either a multi-period excess earnings method or a relief from royalty method to determine the fair value of the asset and use the forecasts that are consistent with those used in the reporting unit analysis. We conduct our definite-lived intangible asset impairment test quarterly when indications of impairment exists. Below is a summary of the various metrics used in our valuations: Year Ended December 31, 2017 Lumara (4.1)% 13.5% MPEEM 5-year average growth rate Discount rate Valuation method 5-year average growth rate Long-term growth rates Discount rate Royalty rate Valuation method Year Ended December 31, 2016 Entocort® - Branded Products (31.7)% (10.0)% 13.0% NA Entocort® - AG Products (30.4)% (4.7)% 10.5% NA MPEEM MPEEM Omega - XLS 3.2% NA 9.5% 4.0% Relief from Royalty Herron Trade Names and Trademarks 4.6% 2.5% 10.8% 11.0% Relief from Royalty Omega - Lifestyle 2.5% 2.0% 9.3% NA MPEEM We recorded Impairment charges on the Consolidated Statements of Operations related to definite-lived intangible assets of $665.6 million during the year ended December 31, 2016.

The carrying amounts of our other financial instruments, consisting of cash and cash equivalents, accounts receivable, accounts payable, short-term debt and variable rate long-term debt, approximate their fair value. NOTE 7 - INVESTMENTS Available for Sale Securities Our available for sale securities are reported in Prepaid expenses and other current assets. Unrealized investment gains (losses) on available for sale securities were as follows (in millions): Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 Equity securities, at cost less impairments $ Gross unrealized gains Gross unrealized losses Estimated fair value of equity securities $ 15.5 1.5 — 17.0 $ $ 16.5 21.7 — 38.2 $ $ 6.4 9.3 (0.8) 14.9 The factors affecting the assessment of impairments include both general financial market conditions and factors specific to a particular company. We recorded impairment charges of $1.8 million and $10.7 million during the year ended December 31, 2016, and the six months ended December 31, 2015, respectively, related to other- than-temporary impairments of marketable equity securities due to prolonged losses incurred on each of the investments. We have evaluated the near-term prospects of the equity securities in relation to the severity and duration of any impairments, and based on that evaluation, we have the ability and intent to hold these investments until a recovery of fair value. We sold a number of our investment securities and recorded gains of $1.6 million and $1.0 million during the years ended December 31, 2017 and December 31, 2016, respectively. The gains were reclassified out of AOCI and into earnings. 138 Perrigo Company plc - Item 8 Note 7 Cost Method Investments Our cost method investments totaled $6.3 million, $6.9 million, and $6.9 million at December 31, 2017, December 31, 2016, and December 31, 2015, respectively, and were included in Other non-current assets. During the year ended December 31, 2017, due to significant and prolonged losses incurred by one of our cost method investments, we recorded a $1.0 million impairment charge in Other (income) expense, net on the Consolidated Statements of Operations. Equity Method Investments Our equity method investments totaled $4.9 million, $4.6 million, and $45.5 million at December 31, 2017, December 31, 2016, and December 31, 2015, respectively, and were included in Other non-current assets. We recorded net gains of $0.3 million, and net losses of $4.1 million, $5.4 million, and $11.6 million during the years ended December 31, 2017 and December 31, 2016, the six months ended December 31, 2015, and the year ended June 27, 2015, respectively, for our proportionate share of the equity method investment earnings or losses. The gains and losses were recorded in Other (income) expense, net on the Consolidated Statements of Operations. During the year ended December 31, 2016, one of our equity method investments became publicly traded. As a result, we transferred the $15.5 million investment to available for sale and recorded an $8.7 million unrealized gain, net of tax in Other Comprehensive Income ("OCI"). In addition, due to significant and prolonged losses incurred on one of our equity method investments, we recorded a $22.3 million impairment charge in Other (income) expense, net on the Consolidated Statements of Operations. NOTE 8 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES We enter into certain derivative financial instruments, when available on a cost-effective basis, to mitigate our risk associated with changes in interest rates and foreign currency exchange rates as follows: Interest rate risk management - We are exposed to the impact of interest rate changes through our cash investments and borrowings. We utilize a variety of strategies to manage the impact of changes in interest rates including using a mix of debt maturities along with both fixed-rate and variable-rate debt. In addition, we may enter into treasury-lock agreements and interest rate swap agreements on certain investing and borrowing transactions to manage our exposure to interest rate changes and our overall cost of borrowing. Foreign currency exchange risk management - We conduct business in several major currencies other than the U.S. dollar and are subject to risks associated with changing foreign exchange rates. Our objective is to reduce cash flow volatility associated with foreign exchange rate changes on a consolidated basis to allow management to focus its attention on business operations. Accordingly, we enter into various contracts that change in value as foreign exchange rates change to protect the value of existing foreign currency assets and liabilities, commitments, and anticipated foreign currency sales and expenses. All derivative instruments are managed on a consolidated basis to efficiently net exposures and thus take advantage of any natural offsets. Gains and losses related to the derivative instruments are expected to be offset largely by gains and losses on the original underlying asset or liability. We do not use derivative financial instruments for speculative purposes. All of our designated derivatives were classified as cash flow hedges as of December 31, 2017, December 31, 2016, and December 31, 2015. Designated derivatives meet hedge accounting criteria, which means the fair value of the hedge is recorded in shareholders’ equity as a component of OCI, net of tax. The deferred gains and losses are recognized in income in the period in which the hedged item affects earnings. Any ineffective portion of the change in fair value of the derivative is immediately recognized in earnings. All of our designated derivatives are assessed for hedge effectiveness quarterly. We also have economic non-designated derivatives that do not meet hedge accounting criteria. These derivative instruments are adjusted to current market value at the end of each period through earnings. Gains or losses on these instruments are offset substantially by the remeasurement adjustment on the hedged item. 139 Perrigo Company plc - Item 8 Note 8 Interest Rate Swaps and Treasury Locks Interest rate swap agreements are contracts to exchange floating rate for fixed rate payments (or vice versa) over the life of the agreement without the exchange of the underlying notional amounts. The notional amounts of the interest rate swap agreements are used to measure interest to be paid or received and do not represent the amount of exposure to credit loss. The differential paid or received on the interest rate swap agreements is recognized as an adjustment to interest expense. During the three months ended July 1, 2017, we repaid $584.4 million of senior notes with an interest rate of 4.000% due 2023 and $309.5 million of senior notes with an interest rate of 5.300% due 2043 (refer to Note 10). As a result of the senior note repayments on June 15, 2017, the proportionate amount remaining in OCI related to the pre-issuance hedge was reclassified to earnings. Accordingly, we recorded a loss of $5.9 million in Other expense, net, during the three months ended July 1, 2017 for the amount remaining in OCI. During the six months ended December 31, 2015, we entered into a forward interest rate swap to hedge against changes in the benchmark interest rate between the date the interest rate swap was entered into and the date of expected future debt issuance. The interest rate swap was designated as a cash flow hedge and had a notional amount totaling $200.0 million. The interest rate swap was settled upon the issuance of an aggregate $1.2 billion principal amount of senior notes on March 7, 2016 for a cumulative after-tax loss of $7.0 million in OCI during the three months ended April 2, 2016. During the year ended June 27, 2015, we repaid a $300.0 million term loan with floating interest rates priced off the LIBOR yield curve (refer to Note 10). As a result of the term loan repayment on June 24, 2015, the forward interest rate swap agreements with notional amounts totaling $240.0 million that were in place to hedge the change in the LIBOR rate were terminated as well. We recorded a loss of $3.6 million in Other expense, net, during the year ended June 27, 2015 for the amount remaining in AOCI when the hedges were terminated. In connection with the Omega acquisition, we assumed a $20.0 million private placement note. We also assumed an interest rate swap agreement with a notional amount totaling $20.0 million that was in place to hedge the cross currency exchange differences between the U.S. dollar and the euro on the above-mentioned debt. On May 29, 2015, we repaid the loan and the interest rate swap. We also assumed €500.0 million ($544.5 million) of debt under Omega's revolving credit facility, as well as an interest rate swap agreement with a notional amount of €135.0 million ($147.0 million) that was in place to hedge the change in the floating rate on that credit facility. On April 8, 2015, we repaid the loan and terminated the interest rate swap. Because both interest rate swaps mentioned above were recorded at fair market value on the date of termination, no gain or loss was recorded. For more information on the acquired debt and termination (refer to Note 10). During the year ended June 27, 2015, we entered into forward interest rate swaps and treasury locks (together "Rate Locks") to hedge against changes in the interest rates between the date the Rate Locks were entered into and the date of the issuance of our 2014 Bonds (refer to Note 10). These Rate Locks were designated as cash flow hedges of expected future debt issuances with a notional amount totaling $750.0 million. The Rate Locks were settled upon the issuance of an aggregate $1.6 billion principal amount of our 2014 Bonds on December 2, 2014 for a cumulative after-tax loss of $5.8 million in OCI after recording $1.1 million of ineffectiveness to Other expense, net, during the year ended June 27, 2015. Foreign Currency Derivatives We enter into foreign currency forward contracts, both designated and non-designated, in order to manage the impact of foreign exchange fluctuations on expected future purchases and related payables denominated in a foreign currency, as well as to hedge the impact of foreign exchange fluctuations on expected future sales and related receivables, and expected future royalties denominated in a foreign currency. Both types of forward contracts have a maximum maturity date of 18 months. The total notional amount for these contracts was $592.3 million, $533.5 million, and $755.5 million, as of December 31, 2017, December 31, 2016, and December 31, 2015, respectively. In June 2015, in order to economically hedge the foreign currency exposure associated with the planned payment of the euro-denominated GSK Products acquisition (refer to Note 2), we entered into a non-designated 140 Perrigo Company plc - Item 8 Note 8 option contract to protect against a strengthening of the euro relative to the U.S. dollar. We recorded losses of $1.9 million for the change in fair value of the option contract during the year ended June 27, 2015 in Other expense, net. Because these derivatives were economically hedging future acquisitions, the cash outflows associated with their settlement are shown as investing activity on the Consolidated Statements of Cash Flows. In November 2014, in order to economically hedge the foreign currency exposure associated with the planned payment of the euro-denominated purchase price of Omega, we entered into non-designated option contracts with a total notional amount of €2.0 billion. The option contracts settled in December 2014, resulting in a loss of $26.4 million. The option contracts were replaced with non-designated forward contracts that matured during the three months ended March 28, 2015. We recorded losses of $298.1 million during the year ended June 27, 2015 related to the settlement of the forward contracts. Both losses were recorded primarily in Other expense, net. The losses on the derivatives due to changes in the euro to U.S. dollar exchange rates were economically offset at closing in the final settlement of the euro-denominated Omega purchase price.

On April 6, 2017, we completed the sale of our India API business (refer to Note 2). The India API business was reported in our Other segment. During the three months ended October 1, 2016, management committed to a plan to sell certain fixed assets associated with our animal health pet treats plant. Such assets were classified as held-for-sale beginning at October 1, 2016. On February 1, 2017, we completed the sale of our animal health pet treats plant fixed assets (refer to Note 2).

We are in compliance with all covenants under our debt agreements as of December 31, 2017. 144 Perrigo Company plc - Item 8 Note 10 Revolving Credit Agreements On December 9, 2015, our 100% owned finance subsidiary, Perrigo Finance Unlimited Company ("Perrigo Finance"), entered into a $750.0 million revolving credit agreement (the "2015 Revolver"). On March 15, 2016, we used the proceeds of the long-term debt issuance described below under "2016 Notes" to repay the $750.0 million then outstanding under the 2015 Revolver and terminated the facility. On March 30, 2015, we assumed a revolving credit facility with €500.0 million ($544.5 million) outstanding from Omega. On April 8, 2015, we repaid the €500.0 million ($539.1 million) outstanding under the assumed revolving credit facility and terminated the facility. On December 5, 2014, Perrigo Finance entered into a $600.0 million revolving credit agreement, which increased to $1.0 billion on March 30, 2015 (the "2014 Revolver"). On March 15, 2016, we used the proceeds of the long-term debt issuance described below under "2016 Notes" to repay the $435.0 million then outstanding under the 2014 Revolver. There were no borrowings outstanding under the 2014 Revolver as of December 31, 2017 or December 31, 2016. Term Loans On December 5, 2014, Perrigo Finance entered into a term loan agreement consisting of a €500.0 million ($614.3 million) tranche, with the ability to draw an additional €300.0 million ($368.6 million) tranche, maturing December 5, 2019; we also entered into a $300.0 million term loan tranche maturing December 18, 2015, which we repaid in full on June 25, 2015. On September 6, 2013, Perrigo Company entered into a $1.0 billion term loan agreement (the "2013 Term Loan") (together with the 2013 Revolver, the "2013 Credit Agreements"). The 2013 Term Loan consisted of a $300.0 million tranche maturing December 18, 2015 and a $700.0 million tranche maturing December 18, 2018. Both tranches were drawn in full on December 18, 2013. Amounts outstanding under the 2013 Credit Agreements bore interest at our option (a) at the alternative base rate or (b) the eurodollar rate plus, in either case, applicable margins as set forth in the 2013 Credit Agreements. Perrigo Company obligations under the 2013 Credit Agreements were guaranteed by Perrigo Company plc, certain U.S. subsidiaries of Perrigo Company plc, Elan, and certain Irish subsidiaries of Elan until November 21, 2014, at which time the terms of the 2013 Credit Agreements were amended to remove all guarantors. On December 5, 2014, we repaid the remaining $895.0 million outstanding under our 2013 Term Loan, then terminated it. We recorded a $10.5 million loss on extinguishment of debt during the year ended June 27, 2015, which consisted of the Bridge Loan Facility interest expense and deferred financing fees related to the 2013 Credit Agreements, and 2013 Term Loan. Notes and Bonds 2016 Notes On March 7, 2016, Perrigo Finance issued $500.0 million in aggregate principal amount of 3.500% senior notes due 2021 and $700.0 million in aggregate principal amount of 4.375% senior notes due 2026 (together, the "2016 Notes") and received net proceeds of $1.2 billion after fees and market discount. Interest on the 2016 Notes is payable semiannually in arrears in March and September of each year, beginning in September 2016. The 2016 Notes are governed by a base indenture and a second supplemental indenture (collectively, the "2016 Indenture"). The 2016 Notes are fully and unconditionally guaranteed on a senior basis by Perrigo, and no other subsidiary of Perrigo guarantees the 2016 Notes. The proceeds were used to repay amounts borrowed under the 2015 Revolver and the 2014 Revolver, as mentioned above. There are no restrictions under the 2016 Notes on our ability to obtain funds from our subsidiaries. Perrigo Finance may redeem the 2016 Notes in whole or in part at any time for cash at the make-whole redemption prices described in the 2016 Indenture. Notes and Bonds Assumed from Omega In connection with the Omega acquisition, on March 30, 2015, we assumed: 145 Perrigo Company plc - Item 8 Note 10 • • • $20.0 million in aggregate principal amount of 6.190% senior notes due 2016, which was repaid on May 29, 2015 in full; €135.0 million ($147.0 million) in aggregate principal amount of 5.105% senior notes due 2023 (the "2023 Notes"); €300.0 million ($326.7 million) in aggregate principal amount of 5.125% retail bonds due 2017; €180.0 million ($196.0 million) in aggregate principal amount of 4.500% retail bonds due 2017; and €120.0 million ($130.7 million) in aggregate principal amount of 5.000% retail bonds due 2019 (collectively, the "Retail Bonds"). The fair value of the 2023 Notes and Retail Bonds exceeded par value by €93.6 million ($101.9 million) on the date of the Omega acquisition. As a result, a fair value adjustment was recorded as part of the carrying value of the underlying debt and will be amortized as a reduction of interest expense over the remaining terms of the respective debt instruments. The adjustment does not affect cash interest payments. 2014 Notes On December 2, 2014, Perrigo Finance issued $500.0 million in aggregate principal amount of 3.500% senior notes due 2021 (the "2021 Notes”), $700.0 million in aggregate principal amount of 3.900% senior notes due 2024 (the “2024 Notes”), and $400.0 million in aggregate principal amount of 4.900% senior notes due 2044 (the “2044 Notes” and, together with the 2021 Notes and the 2024 Notes, the “2014 Notes”) and received net proceeds of $1.6 billion after fees and market discount. Interest on the 2014 Notes is payable semiannually in arrears in June and December of each year, beginning in June 2015. The 2014 Notes are governed by a base indenture and a first supplemental indenture (collectively, the "2014 Indenture"). The 2014 Notes are fully and unconditionally guaranteed on a senior unsecured basis by Perrigo, and no other subsidiary of Perrigo guarantees the 2014 Notes. There are no restrictions under the 2014 Notes on our ability to obtain funds from our subsidiaries. Perrigo Finance may redeem the 2014 Notes in whole or in part at any time for cash at the make-whole redemption prices described in the 2014 Indenture. 2013 Notes On November 8, 2013, Perrigo Company issued $500.0 million aggregate principal amount of its 1.300% senior notes due 2016 (the "1.300% 2016 Notes"), $600.0 million aggregate principal amount of its 2.300% senior notes due 2018 (the "2018 Notes"), $800.0 million aggregate principal amount of its 4.000% senior notes due 2023 (the "4.000% 2023 Notes") and $400.0 million aggregate principal amount of its 5.300% senior notes due 2043 (the "2043 Notes" and, together with the 1.300% 2016 Notes, the 2018 Notes and the 4.000% 2023 Notes, the "2013 Notes") in a private placement with registration rights. We received net proceeds of $2.3 billion from the issuance of the 2013 Notes after fees and market discount. On September 29, 2016, we repaid all $500.0 million of the 1.300% 2016 Notes outstanding. Interest on the 2013 Notes is payable semiannually in arrears in May and November of each year, beginning in May 2014. The 2013 Notes are governed by a base indenture and a first supplemental indenture (collectively, the "2013 Indenture"). The 2013 Notes are our unsecured and unsubordinated obligations, ranking equally in right of payment to all of our existing and future unsecured and unsubordinated indebtedness. The 2013 Notes are not entitled to mandatory redemption or sinking fund payments. We may redeem the 2013 Notes in whole or in part at any time for cash at the make-whole redemption prices described in the 2013 Indenture. The 2013 Notes were guaranteed on an unsubordinated, unsecured basis by the same entities that guaranteed our then- outstanding credit agreement until November 21, 2014, at which time the 2013 Indenture was amended to remove all guarantors. On September 2, 2014, we offered to exchange our private placement senior notes for public bonds (the "Exchange Offer"). The Exchange Offer expired on October 1, 2014, at which time substantially all of the private placement notes had been exchanged for bonds registered with the Securities and Exchange Commission. As a result of the changes in the guarantor structure noted above, we are no longer required to present guarantor financial statements. 146 Perrigo Company plc - Item 8 Note 10 Other Financing Overdraft Facilities We have overdraft facilities available that we use to support our cash management operations. We report any balances outstanding in the above table under "Other financing". The balance outstanding under the facilities was $6.9 million and $82.9 million at December 31, 2017 and December 31, 2015 respectively, and there were no balances outstanding under the facilities at December 31, 2016.

We paid dividends as follows: Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 Year Ended June 27, 2015 Dividends paid (in millions) Dividends paid (per share) $ $ 91.1 0.64 $ $ 148 83.2 0.58 $ $ 36.3 0.25 $ $ 64.8 0.46 Perrigo Company plc - Item 8 Note 11 The declaration and payment of dividends and the amount paid, if any, are subject to the discretion of the Board of Directors and depend on our earnings, financial condition, capital and surplus requirements and other factors the Board of Directors may consider relevant. Share Repurchases In October 2015, the Board of Directors approved a share repurchase plan of up to $2.0 billion (the "2015 Authorization"). We did not repurchase any shares under the share repurchase plan during the three months ended December 31, 2017. During the year ended December 31, 2017, we repurchased 2.7 million ordinary shares at an average repurchase price of $71.72 per share, for a total of $191.5 million. We did not repurchase any shares under the share repurchase plan during the year ended December 31, 2016. During the six months ended December 31, 2015, we repurchased 3.3 million ordinary shares at an average repurchase price of $151.59 per share, for a total of $500.0 million. NOTE 12 - SHARE-BASED COMPENSATION PLANS All share-based compensation for employees and directors is granted under the 2013 Long-Term Incentive Plan, as amended (the "Plan"). The Plan has been approved by our shareholders and provides for the granting of awards to our employees and directors. As of December 31, 2017, there were 3.8 million shares available to be granted. The purpose of the Plan is to attract and retain individuals of exceptional talent and encourage these individuals to acquire a vested interest in our success and prosperity. The awards that may be granted under this program include non-qualified stock options, restricted shares, restricted share units, and RTSR units. Restricted shares are generally service-based, requiring a certain length of service before vesting occurs, while restricted share units can be either service-based or performance-based. Performance-based restricted share units require a certain length of service until vesting; however, they contain an additional performance feature, which can vary the amount of shares ultimately paid out based on certain performance criteria specified in the Plan. RTSR performance share units are subject to a market condition. Awards granted under the Plan vest and may be exercised and/or sold from one to ten years after the date of grant based on a vesting schedule. Share-based compensation expense was as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 43.8 $ 23.0 $ 22.8 $ 31.6 As of December 31, 2017, unrecognized share-based compensation expense was $51.2 million, and the weighted-average period over which the expense is expected to be recognized was approximately 2.0 years. Proceeds from the exercise of stock options are credited to ordinary shares. 149 Perrigo Company plc - Item 8 Note 12 Stock Options A summary of activity related to stock options is presented below (options in thousands): Weighted- Average Exercise Price Per Share Weighted- Average Remaining Term in Years Aggregate Intrinsic Value Number of Options Options outstanding at December 31, 2015 Granted Exercised Forfeited or expired Options outstanding at December 31, 2016 Granted Exercised Forfeited or expired Options outstanding December 31, 2017 Options exercisable Options expected to vest 783 344 $ $ (122) $ (256) $ 749 439 $ $ (31) $ (85) $ 1,072 519 533 $ $ $ 99.93 126.67 67.68 126.54 108.40 70.34 24.75 118.47 94.90 107.14 83.63 6.6 $ 5.5 6.9 5.0 8.7 $ $ $ 10.9 3.8 6.8 The aggregate intrinsic value for options exercised was as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 1.7 $ 5.2 $ 6.7 $ 20.7 The weighted-average fair values per share at the grant date for options granted were $19.50, $33.53, and $39.96 for the years ended December 31, 2017, December 31, 2016, and June 27, 2015, respectively. There were no options granted during the six months ended December 31, 2015. The fair values were estimated using the Black-Scholes option pricing model with the following weighted-average assumptions: Dividend yield Volatility, as a percent Risk-free interest rate Expected life in years Year Ended December 31, 2017 December 31, 2016 June 27, 2015 0.9% 30.0% 1.8% 5.41 0.5% 27.6% 1.3% 5.5 0.3% 27.1% 1.7% 5.3 The valuation model utilizes historical volatility. The risk-free interest rate is based on the yield of U.S. government securities with a maturity date that coincides with the expected term of the option. The expected life in years is estimated based on past exercise behavior of employees. Non-Vested Restricted Shares There were no restricted shares granted, vested or outstanding for the years ended December 31, 2017 or December 31, 2016, the six months ended December 31, 2015, or the year ended June 27, 2015. The total fair value of restricted shares that vested was $0.9 million for the year ended June 27, 2015. 150 Perrigo Company plc - Item 8 Note 12 Non-Vested Service-Based Restricted Share Units A summary of activity related to non-vested service-based restricted share units is presented below (units in thousands): Number of Non-vested Service- Based Share Units Weighted- Average Grant Date Fair Value Per Share Weighted- Average Remaining Term in Years Aggregate Intrinsic Value Non-vested service-based share units outstanding at December 31, 2015 Granted Vested Forfeited Non-vested service-based share units outstanding at December 31, 2016 Granted Vested Forfeited 382 298 $ $ (92) $ (120) $ 468 298 $ $ (112) $ (55) $ 154.07 113.26 137.15 151.64 137.53 70.55 128.86 120.97 1.7 $ 39.0 Non-vested service-based share units outstanding at December 31, 2017 599 $ 107.26 1.5 $ 52.2 The weighted-average fair value per share at the date of grant for service-based restricted share units granted was as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 70.55 $ 113.26 $ 165.64 $ 153.99 The total fair value of service-based restricted share units that vested was as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 14.5 $ 12.6 $ 11.7 $ 9.1 151 Perrigo Company plc - Item 8 Note 12 Non-Vested Performance-Based Restricted Share Units A summary of activity related to non-vested performance-based restricted share units is presented below (units in thousands): Number of Non-vested Performance- Based Share Units Weighted- Average Grant Date Fair Value Per Share Weighted- Average Remaining Term in Years* Aggregate Intrinsic Value Non-vested performance-based share units outstanding at December 31, 2015 Granted Vested Forfeited Non-vested performance-based share units outstanding at December 31, 2016 Granted Vested Forfeited 223 159 $ $ (81) $ (124) $ 177 191 $ $ (27) $ (38) $ 146.31 126.37 128.74 143.64 138.29 70.34 142.18 130.34 1.7 $ 14.8 Non-vested performance-based share units outstanding at December 31, 2017 303 $ 93.65 2.0 $ 26.5 The weighted-average fair value of performance-based restricted share units can fluctuate depending upon the success or failure of the achievement of performance criteria as set forth in the Plan. The weighted-average fair value per share at the date of grant for performance-based restricted share units granted was as follows: Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 70.34 $ 126.37 $ 184.49 $ 150.14 The total fair value of performance-based restricted share units that vested was as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 3.8 $ 10.4 $ 6.4 $ 5.1 Non-vested Relative Total Shareholder Return Performance Share Units The fair value of the RTSR performance share units is determined using the Monte Carlo pricing model as the number of shares to be awarded is subject to a market condition. The valuation model considers a range of possible outcomes, and compensation cost is recognized regardless of whether the market condition is actually satisfied. The assumptions used in estimating the fair value of the RTSR performance share units granted during each year were as follows: 152 Perrigo Company plc - Item 8 Note 12 Dividend yield Volatility, as a percent Risk-free interest rate Expected life in years Year Ended December 31, 2017 0.9% 36.1% 1.4% 2.57 A summary of activity related to non-vested RTSR performance share units is presented below (units in thousands): Number of Non-vested RTSR Performance Share Units Weighted- Average Grant Date Fair Value Per Share Weighted- Average Remaining Term in Years* Aggregate Intrinsic Value 0 $ — 2.0 $ 3.4 Non-vested RTSR performance share units outstanding at December 31, 2016 Granted Non-vested RTSR performance share units outstanding at December 31, 2017 * Midpoint used in calculation. — $ 39 39 $ $ — 64.82 64.82 The weighted-average fair value per share at the date of grant for RTSR performance share units granted was $64.82.

No further provision has been made for income taxes on remaining undistributed earnings of foreign subsidiaries of approximately $6.3 billion at December 31, 2017, since it is our intention to indefinitely reinvest undistributed earnings of our foreign subsidiaries. Due to the complexity of the legal entity structure and the complexity of the tax laws in various jurisdictions, we believe it is not practicable to estimate, within any reasonable range, the additional income taxes that may be payable on the remittance of such undistributed earnings. 155 Deferred income taxes arise from temporary differences between the financial reporting and the tax reporting basis of assets and liabilities and operating loss and tax credit carryforwards for tax purposes. The components of our net deferred income tax asset (liability) were as follows: Perrigo Company plc - Item 8 Note 14 Deferred income tax asset (liability): Depreciation and amortization Inventory basis differences Accrued liabilities Allowance for doubtful accounts Research and development Loss and credit carryforwards Share-based compensation Foreign tax credit Federal benefit of unrecognized tax positions Interest carryforwards Other, net Subtotal Valuation allowance Net deferred income tax asset (liability): $ $ December 31, 2017 December 31, 2016 December 31, 2015 $ (457.8) $ (765.2) $ (1,550.6) 21.3 87.9 1.5 58.9 292.5 16.2 — 17.0 30.5 28.2 96.2 27.4 68.5 1.7 61.7 292.4 18.1 10.6 24.3 435.3 3.0 $ 177.8 $ (407.7) (495.6) 22.8 50.8 1.3 63.7 244.2 20.6 10.6 22.8 334.6 14.7 (764.5) (536.8) (311.5) $ (317.8) $ (1,301.3) The above amounts are classified on the Consolidated Balance Sheets as follows (in millions): Assets Liabilities Net deferred income tax (liability) asset December 31, 2017 December 31, 2016 December 31, 2015 $ $ 10.4 $ 72.1 $ (321.9) (389.9) (311.5) $ (317.8) $ 71.4 (1,372.7) (1,301.3) At December 31, 2017, we had gross carryforwards as follows: U.S. state net operating losses $ Worldwide federal net operating losses excluding U.S. states $ Worldwide federal capital losses U.S. federal credits U.S. state credits Interest carryforwards $ $ $ $ December 31, 2017 Gross Carryforwards(1) Gross Valuation Allowances 248.5 1,389.0 22.0 82.6 71.9 478.8 $ $ $ $ $ $ 203.6 861.6 22.0 82.6 71.9 127.0 (1) Utilization of such carryforwards within the applicable statutory periods is uncertain. In 2017, we recorded income tax expense related to valuation allowances of $10.3 million in Ireland. In addition, we released valuation allowances of $42.4 million and $55.8 million for Omega and the U.S. and other jurisdictions, respectively, resulting in a tax benefit. 156 Perrigo Company plc - Item 8 Note 14 U.S. federal credit carryforwards of $28.2 million, $37.2 million and $167.8 million expire through 2022, 2025 and 2027, respectively, with the remaining U.S. credits having no expiration. U.S. state net operating loss carryforwards expire through 2037, and U.S. state credit carryforwards expire through 2032. Of the non-U.S. net operating loss carryforwards, $1.8 million, $20.3 million, $0.9 million, and $0.1 million expire through 2019, 2022, 2024 and 2025, respectively, while the remaining amounts of non U.S. net operating loss carryforwards and non- U.S. capital loss carryforwards have no expiration. The valuation allowances for these net operating loss carryforwards are adjusted annually, as necessary. After application of the valuation allowances, as described above, we anticipate no significant limitations will apply with respect to the realization of our net deferred income tax assets. The following table summarizes the activity related to amounts recorded for uncertain tax positions, excluding interest and penalties (in millions): Balance at June 27, 2015 Additions: Positions related to the current year Reductions: Positions related to prior years Settlements with taxing authorities Balance at December 31, 2015 Additions: Positions related to the current year Positions related to prior years Reductions: Settlements with taxing authorities Lapse of statutes of limitation Balance at December 31, 2016 Additions: Positions related to the current year Positions related to prior years Reductions: Settlements with taxing authorities Lapse of statutes of limitation Decrease in prior year positions Unrecognized Tax Benefits $ 324.0 22.9 (43.5) (15.3) 288.1 45.5 8.6 (2.4) (5.3) 334.5 55.0 76.6 (11.1) (0.1) (35.2) 419.7 Balance at December 31, 2017 $ We recognize interest and penalties related to uncertain tax positions as a component of income tax expense. The total amount accrued for interest and penalties in the liability for uncertain tax positions was $82.0 million, $63.5 million, and $52.1 million as of December 31, 2017, December 31, 2016, and December 31, 2015, respectively. The total liability for uncertain tax positions was $501.7 million, $398.0 million, and $340.3 million as of December 31, 2017, December 31, 2016, and December 31, 2015, respectively, before considering the federal tax benefit of certain state and local items, of which $204.0 million, $248.7 million, and $198.5 million, respectively, would impact the effective tax rate in future periods, if recognized. We file income tax returns in numerous jurisdictions and are therefore subject to audits by tax authorities. Our primary income tax jurisdictions are Ireland, U.S., Israel, Belgium, France, and the United Kingdom. Although we believe that our tax estimates are reasonable and that we prepare our tax filings in accordance with all applicable tax laws, the final determination with respect to any tax audit and any related litigation could be materially different from our estimates or from our historical income tax provisions and accruals. The results of an 157 Perrigo Company plc - Item 8 Note 14 audit or litigation could have a material effect on operating results and/or cash flows in the periods for which that determination is made. In addition, future period earnings may be adversely impacted by litigation costs, settlements, penalties, and/or interest assessments. On August 15, 2017, we filed a complaint in the U.S. District Court for the Western District of Michigan to recover $163.6 million of Federal income tax, penalties, and interest assessed and collected by the Internal Revenue Service (“IRS”), plus statutory interest thereon from the dates of payment, for the fiscal years ended June 27, 2009, June 26, 2010, June 25, 2011, and June 30, 2012 (the “2009 tax year,” “2010 tax year,” “2011 tax year,” and “2012 tax year,” respectively). The IRS audits of those years culminated in the issuances of two statutory notices of deficiency: (1) on August 27, 2014 for the 2009 and 2010 tax years and (2) on April 20, 2017 for the 2011 and 2012 tax years. The statutory notices of deficiency both included un-agreed income adjustments related principally to transfer pricing adjustments regarding the purchase, distribution, and sale of store-brand OTC pharmaceutical products in the United States. In addition, the statutory notice of deficiency for the 2011 and 2012 tax years included the capitalization of certain expenses that were deducted when paid or incurred in defending against certain patent infringement lawsuits. We fully paid the assessed amounts of tax, interest, and penalties set forth in the statutory notices and filed timely claims for refund on June 11, 2015 and June 7, 2017 for the 2009-2010 tax years and 2011-2012 tax years, respectively. Our claims for refund were disallowed by certified letters dated August 18, 2015 and July 11, 2017, for the 2009-2010 tax years and 2011-2012 tax years, respectively. The complaint was timely, based upon the refund claim denials, and seeks refunds of tax, interest, and penalties of $37.2 million for the 2009 tax year, $61.5 million for the 2010 tax year, $40.2 million for the 2011 tax year, and $24.7 million for the 2012 tax year. The amounts sought in the complaint for the 2009 and 2010 tax years were recorded as deferred charges on our balance sheet during the three months ended March 28, 2015, and the amounts sought in the complaint for the 2011 and 2012 tax years were recorded as deferred charges on our balance sheet during the three months ended July 1, 2017. On December 22, 2016, we received a notice of proposed adjustment for the IRS audit of Athena Neurosciences, Inc. (“Athena”), a subsidiary of Elan acquired in 1996, for the years ended December 31, 2011, December 31, 2012, and December 31, 2013. Perrigo acquired Elan in December 2013. This proposed adjustment relates to the deductibility of litigation costs. We disagree with the IRS’s position asserted in the notice of proposed adjustment and intend to contest it. On July 11, 2017, we received a draft notice of proposed adjustment associated with transfer pricing positions for the IRS audit of Athena for the years ended December 31, 2011, December 31, 2012, and December 31, 2013. Athena was the originator of the patents associated with Tysabri® prior to the acquisition of Athena by Elan in 1996. In response to the draft notice of proposed adjustment, we provided the IRS with substantial additional documentation supporting our position. The amount of adjustments that may be asserted by the IRS in the final notice of proposed adjustment cannot be quantified at this time; however, based on the draft notice received, the amount to be assessed may be material. We disagree with the IRS’s position as asserted in the draft notice of proposed adjustment and intend to contest it. We have ongoing audits in multiple other jurisdictions the resolution of which remains uncertain. These jurisdictions include, but are not limited to, the U.S., Israel, Ireland and other jurisdictions in Europe. In addition to the matters discussed above, the IRS is currently auditing our fiscal years ended June 29, 2013, June 28, 2014, and June 27, 2015. The Israel Tax Authority is currently auditing our fiscal years ended June 29, 2013 and June 28, 2014 (which covers the period of the Elan transaction). The Ireland Tax Authority is currently auditing our years ended December 31, 2012 and December 31, 2013. Based on the final resolution of tax examinations, judicial or administrative proceedings, changes in facts or law, expirations of statute of limitations in specific jurisdictions or other resolutions of, or changes in, tax positions, it is reasonably possible that unrecognized tax benefits for certain tax positions taken on previously filed tax returns may change materially from those represented on the financial statements as of December 31, 2017. During the next 12 months, it is reasonably possible that such circumstances may occur that would have a material effect on previously unrecognized tax benefits. As a result, the total net amount of unrecognized tax benefits may decrease, which would reduce the provision for taxes on earnings by a range estimated at $1.0 million to $17.9 million. 158 Perrigo Company plc - Item 8 Note 14 Tax Law Changes On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (“U.S. Tax Act”). The U.S. Tax Act includes a number of significant changes to existing U.S. tax laws that impact the Company. These changes include a corporate income tax rate reduction from 35% to 21% and the elimination or reduction of certain U.S. deductions and credits including limitations on the U.S. deductibility of interest expense and executive compensation. The U.S. Tax Act also transitions the U.S. taxation of international earnings from a worldwide system to a modified territorial system. These changes are effective beginning in 2018. The U.S. Tax Act also includes a one-time mandatory deemed repatriation tax on accumulated U.S. owned foreign corporations’ previously untaxed foreign earnings (“Transition Toll Tax”). The Transition Toll Tax may be paid over an eight-year period, starting in 2018, and will not accrue interest. On December 22, 2017, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of the U.S. GAAP ASC 740 income tax accounting for tax law changes enacted during 2017, in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the U.S. Tax Act. In accordance with SAB 118, we have recorded an income tax benefit of $2.4 million in connection with the remeasurement of certain deferred tax assets and liabilities. We also recorded a $17.5 million increase of current tax expense in connection with the Transition Toll Tax on cumulative U.S. owned foreign earnings of $1.2 billion. The tax impacts represent provisional amounts and are a reasonable estimate at December 31, 2017. Additional work is necessary to perform additional analysis of historical foreign earnings and U.S. cumulative temporary differences, as well as potential correlative adjustments. Any subsequent adjustment to these amounts will be recorded to current tax expense in 2018 when the analysis is complete. The U.S. Tax Act subjects a U.S. shareholder to tax on global intangible low-taxed income (GILTI) earned by certain foreign subsidiaries. The FASB Staff Q&A, Topic 740, No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred. Given the complexity of the GILTI provisions, we are still evaluating the effects of the GILTI provisions and have not yet determined our accounting policy. At December 31, 2017, because we are still evaluating the GILTI provisions and our analysis of future taxable income that is subject to GILTI, we are unable to make a reasonable estimate and have not reflected any adjustments related to GILTI in our financial statements. On December 22, 2017, the Belgian Parliament approved Belgian tax reform legislation (“Belgium Tax Act”), which was signed by the Belgian King and enacted on December 25, 2017. The Belgium Tax Act provides for a reduction to the corporate income tax rate from 34% to 30%, for 2018 and 2019, as well as a reduced corporate income tax rate of 25% for 2020 and beyond. The Belgium Tax Act also increased the participation exemption on dividend distributions to Belgium entities from 95% to 100%. The Belgium Tax Act also introduces Belgium tax consolidation and other anti-tax avoidance directives. We recorded an additional income tax expense of $24.1 million for the remeasurement of certain deferred tax assets and additional income tax benefit of $33.2 million for the remeasurement of certain deferred tax liabilities as a result of the Belgium Tax Act. For the years ended December 31, 2016 and December 31, 2015, statutory rate changes, primarily in Europe, favorably impacted the effective tax rate in the amount of $4.0 million and $27.9 million, respectively. NOTE 15 - POST EMPLOYMENT PLANS Defined Contribution Plans We have a qualified profit-sharing and investment plan under Section 401(k) of the IRS, which covers substantially all U.S. employees. Our contributions to the plan include an annual nondiscretionary contribution of 3% of an employee's eligible compensation and a discretionary contribution at the option of the Board of Directors. Additionally, we match a portion of employees' contributions. We also have a defined contribution plan that covers our Ireland employees. We contribute up to 18% of each participating employee’s annual eligible salary on a monthly basis. 159 Perrigo Company plc - Item 8 Note 15 We assumed a number of defined contribution plans associated with the Omega acquisition and we pay contributions to the pension insurance plans. Our contributions to all of the plans were as follows (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015* $ 25.5 $ 26.1 $ 18.9 $ 25.9 * Includes Omega activity from March 30, 2015 to June 27, 2015 Pension and Post-Retirement Healthcare Benefit Plans We assumed the liability of two defined benefit plans (staff and executive plan) for employees based in Ireland with the Elan acquisition in 2013. These plans were subsequently merged and all plan assets and liabilities were transferred from the executive scheme to the staff scheme as a result of a plan combination. In connection with the Omega acquisition, we assumed the liability of a number of defined benefit plans. The defined benefit plans cover employees based primarily in the Netherlands, Belgium, Germany, Switzerland, Greece, France, and Norway. Omega companies operate various pension plans across each country. Our defined benefit pension plans are managed externally and the related pension costs and liabilities are assessed at least annually in accordance with the advice of a qualified professional actuary. We used a December 31, 2017 measurement date and all plan assets and liabilities are reported as of that date. We provide certain healthcare benefits to eligible U.S. employees and their dependents who meet certain age and service requirements when they retire. Generally, benefits are provided to eligible retirees after age 65 and to their dependents. Increases in our contribution for benefits are limited to increases in the Consumer Price Index. Additional healthcare cost increases are paid through participant contributions. We accrue the expected costs of such benefits during a portion of the employees’ years of service. The plan is not funded. Under current plan provisions, the plan is not eligible for any U.S. federal subsidy related to the Medicare Modernization Act of 2003 Part D Subsidy. 160 Perrigo Company plc - Item 8 Note 15 The change in the projected benefit obligation and plan assets consisted of the following (in millions): Pension Benefits Other Benefits Year Ended Six Months Ended Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 December 31, 2017 December 31, 2016 December 31, 2015 Projected benefit obligation at beginning of period $ 158.9 $ 135.0 $ 140.3 $ 5.8 $ 7.0 $ Acquisitions Curtailment Service costs Interest cost Actuarial (gain) loss Contributions paid Benefits paid Foreign currency translation — (1.0) 4.5 3.3 (10.3) 0.1 (2.5) 21.0 — — 4.1 3.6 22.6 0.3 (1.7) (5.0) 5.6 — 2.2 1.7 (10.1) — (0.6) (4.1) — — 0.6 0.2 (0.3) — (0.1) — — — 0.6 0.2 (1.9) — (0.1) — Projected benefit obligation at end of period $ 174.0 $ 158.9 $ 135.0 $ 6.2 $ 5.8 $ Fair value of plan assets at beginning of period 138.2 126.7 128.1 Acquisitions Actual return on plan assets Benefits paid Employer contributions Contributions paid Foreign currency translation Fair value of plan assets at end of period Unfunded status Presented as: Other non-current assets Other non-current liabilities — 5.5 (2.5) 2.2 0.1 19.0 — 9.4 (1.7) 8.2 0.3 (4.7) 3.2 (1.7) (0.6) 1.4 — (3.7) $ $ $ $ 162.5 $ (11.5) $ 138.2 $ (20.7) $ 126.7 $ (8.3) $ 22.0 $ (33.5) $ 10.4 $ (31.1) $ 16.5 $ (24.8) $ — — — — — — — — $ (6.2) $ — $ — $ — — — — — — — — $ (5.8) $ — $ (5.8) $ The total accumulated benefit obligation for the defined benefit pension plans was as follows (in millions): 6.0 — — 0.3 0.1 0.5 — (0.1) 0.1 7.0 — — — — — — — — (7.0) — (7.0) Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 $ 167.6 $ 136.3 $ 109.4 The following unrecognized actual gains (losses) for the other benefits liability was included in OCI, net of tax (in millions): Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015 $ 0.3 $ (0.7) $ (0.4) $ 0.1 161 The unamortized net actuarial loss in AOCI net of tax for defined benefit pension and other benefits was as follows (in millions): Perrigo Company plc - Item 8 Note 15 Year Ended Six Months Ended Year Ended December 31, 2017 December 31, 2016 December 31, 2015 June 27, 2015* $ (1.3) $ 9.5 $ 2.9 $ 8.2 * Includes Omega activity from March 30, 2015 to June 27, 2015 The total estimated credit amount to be recognized from AOCI into net periodic cost during the next year is $0.7 million.

As of December 31, 2017, the expected weighted-average long-term rate of return on assets of 2.9% was calculated based on the assumptions of the following returns for each asset class: Equities Bonds Absolute return fund Insurance contracts Other 6.0% 1.9% 4.0% 2.8% 2.5% The investment mix of the pension plans' assets is a blended asset allocation, with a diversified portfolio of shares listed and traded on recognized exchanges. Certain of our plans have target asset allocation ranges, as of December 31, 2017 these ranges are as follows: Equities Bonds Absolute return 10% - 20% 20% - 30% 50% - 60% Other plans do not have target asset allocation ranges, for such plans the strategy is to invest primarily 100% in Insurance Contracts. The purpose of the pension funds is to provide a flow of income for members in retirement. A flow of income delivered through fixed interest bonds provides a costly but close match to this objective. Equities are held within the portfolio as a means of reducing this cost, but holding equities creates a strategic risk because they give a very different pattern of return. Property investments are held to help diversify the portfolio. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies, and investment portfolio reviews. 163 Perrigo Company plc - Item 8 Note 15 The following table sets forth the fair value of the pension plan assets, as of December 31, 2017 (in millions): Quoted Prices in Active Markets Other Observable Inputs Unobservable Inputs (Level 1) (Level 2) (Level 3) Total Equities Bonds Insurance contracts Absolute return fund Other Total $ $ 0.1 1.8 — — — $ 19.1 $ — $ 30.2 — 54.5 6.0 — 50.8 — — 19.2 32.0 50.8 54.5 6.0 1.9 $ 109.8 $ 50.8 $ 162.5 The following table sets forth the fair value of the pension plan assets, as of December 31, 2016 (in millions): Quoted Prices in Active Markets Other Observable Inputs Unobservable Inputs (Level 1) (Level 2) (Level 3) Total Equities Bonds Insurance contracts Absolute return fund Other Total $ $ $ 0.1 1.6 — — — 13.6 22.8 — 51.5 5.2 $ — $ — 43.4 — — 13.7 24.4 43.4 51.5 5.2 1.7 $ 93.1 $ 43.4 $ 138.2 The following table sets forth the fair value of the pension plan assets, as of December 31, 2015 (in millions): Other Observable Inputs Unobservable Inputs (Level 2) (Level 3) Total Equities Bonds Property Insurance contracts Absolute return fund Other Total $ $ 14.5 38.1 — — 33.7 5.2 $ — $ — 0.3 34.9 — — 14.5 38.1 0.3 34.9 33.7 5.2 91.5 $ 35.2 $ 126.7 For a discussion of the fair value levels and the valuation methodologies used to measure equities, bonds, and the absolute return fund (refer to Note 6). 164 The following table sets forth a summary of the changes in the fair value of the Level 3 pension plan assets, which were measured at fair value on a recurring basis (in millions): Perrigo Company plc - Item 8 Note 15 Assets at beginning of year Actual return on plan assets Purchases, sales and settlements, net Net transfers Foreign exchange Assets at end of year Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 $ $ 43.4 $ 35.2 $ 1.0 0.9 — 5.5 6.7 (4.2) 7.6 (1.9) 50.8 $ 43.4 $ 34.3 0.1 2.1 — (1.3) 35.2 All properties in the fund are valued by independent valuation experts by forecasting the returns of the market at regular intervals. The inputs to the forecasts include gross national product growth, interest rates and inflation. The fair value of the insurance contracts is an estimate of the amount that would be received in an orderly sale to a market participant at the measurement date. The amount the plan would receive from the contract holder if the contracts were terminated is the primary input and is unobservable. The insurance contracts are therefore classified as Level 3 investments. Deferred Compensation Plans We have non-qualified plans related to deferred compensation and executive retention that allow certain employees and directors to defer compensation subject to specific requirements. Although the plans are not formally funded, we own insurance policies that had a cash surrender value of $34.6 million, $32.7 million and $34.6 million at December 31, 2017, December 31, 2016, and December 31, 2015, respectively, that are intended as a long-term funding source for these plans. The assets, which are recorded in Other non-current assets, are not a committed funding source and may, under certain circumstances, be subject to claims from creditors. The deferred compensation liability of $31.6 million, $29.3 million, and $34.5 million at December 31, 2017, December 31, 2016, and December 31, 2015, respectively, was recorded in Other non-current liabilities. NOTE 16 - COMMITMENTS AND CONTINGENCIES We lease certain assets, principally warehouse facilities and computer equipment, under agreements that expire at various dates through the year ended December 31, 2024. Certain leases contain provisions for renewal and purchase options and require us to pay various related expenses. Future non-cancelable minimum operating lease commitments are as follows (in millions): $ Due 2018 2019 2020 2021 2022 Thereafter Amount 38.1 31.9 24.3 18.6 13.7 16.6 Rent expense under all leases was $50.9 million, $53.0 million, $26.2 million, and $39.2 million for the years ended December 31, 2017 and December 31, 2016, the six months ended December 31, 2015, and the year ended June 27, 2015, respectively. 165 Perrigo Company plc - Item 8 Note 16 At December 31, 2017, we had non-cancelable purchase obligations totaling $771.0 million consisting of contractual commitments to purchase materials and services to support operations. The obligations are expected to be paid within one year. In view of the inherent difficulties of predicting the outcome of various types of legal proceedings, we cannot determine the ultimate resolution of the matters described below. We establish reserves for litigation and regulatory matters when losses associated with the claims become probable and the amounts can be reasonably estimated. The actual costs of resolving legal matters may be substantially higher or lower than the amounts reserved for those matters. For matters where the likelihood or extent of a loss is not probable or cannot be reasonably estimated as of December 31, 2017, we have not recorded a loss reserve. If certain of these matters are determined against us, there could be a material adverse effect on our financial condition, results of operations, or cash flows. We currently believe we have valid defenses to the claims in these lawsuits and intend to defend these lawsuits vigorously regardless of whether or not we have a loss reserve. Other than what is disclosed below, we do not expect the outcome of the litigation matters to which we are currently subject to, individually or in the aggregate, have a material adverse effect on our financial condition, results of operations, or cash flows. Antitrust Violations We were named as a counterclaim co-defendant in the lawsuit Fera Pharmaceuticals, LLC v. Akorn, Inc., et al. in the Southern District of New York, in which Akorn, Inc. (“Akorn”) alleged tortious interference and antitrust violations against us and Fera Pharmaceuticals, LLC (“Fera”). Trial was set for February 2018 in the Southern District of New York. This litigation arose out of our acquisition of bacitracin ophthalmic ointment from Fera in 2013. Akorn asserted claims under Sections 1 and 2 of the Sherman Antitrust Act alleging that we and Fera conspired to monopolize, attempted to monopolize, and did unlawfully monopolize the market for sterile bacitracin ophthalmic ointment in the United States through the use of an exclusive agreement with a supplier of sterile bacitracin active pharmaceutical ingredient. The parties have executed a written settlement of all claims and the case has been dismissed. Price-Fixing Lawsuits We have been named as a co-defendant with other manufacturers in a number of class actions alleging that we and other manufacturers of the same product engaged in anti-competitive behavior to fix or raise the prices of certain drugs starting, in some instances, as early as June 2013. The products in question are Clobetasol, Desonide, and Econazole. These complaints, along with complaints filed against other companies alleging price fixing with respect to more than two dozen other drugs, have been consolidated for pretrial proceedings as part of a case captioned In re Generic Pharmaceuticals Pricing Antitrust Litigation, MDL No. 2724 in the U.S. District Court for the Eastern District of Pennsylvania. Pursuant to the court’s schedule staging various cases in phases, we have moved to dismiss the complaints relating to Clobetasol and Econazole. We have also recently been named a defendant along with 31 other manufacturers in a complaint filed by three supermarket chains alleging that defendants conspired to fix prices of all generic pharmaceutical products starting in 2013. At this stage, we cannot reasonably predict the outcome of the liability, if any, associated with these claims. Securities Litigation In the United States On May 18, 2016, a shareholder filed a securities case against us and our former CEO, Joseph Papa, in the U.S. District Court for the District of New Jersey (Roofers’ Pension Fund v. Papa, et al.). The plaintiff purported to represent a class of shareholders for the period from April 21, 2015 through May 11, 2016, inclusive. The original complaint alleged violations of Securities Exchange Act sections 10(b) (and Rule 10b 5) and 14(e) against both defendants and 20(a) control person liability against Mr. Papa. In general, the allegations concerned the actions taken by us and the former executive to defend against the unsolicited takeover bid by Mylan in the period from April 21, 2015 through November 13, 2015. The plaintiff also alleged that the defendants provided inadequate disclosure concerning alleged integration problems related to the Omega acquisition in the period from April 21, 2015 through May 11, 2016. On July 19, 2016, a different shareholder filed a securities class action against us and our former CEO, Joseph Papa, also in the District of New Jersey (Wilson v. Papa, et al.). The plaintiff purported to represent a class of persons who sold put options on our shares between April 21, 2015 and May 11, 2016. In 166 Perrigo Company plc - Item 8 Note 16 general, the allegations and the claims were the same as those made in the original complaint filed in the Roofers' Pension Fund case described above. On December 8, 2016, the court consolidated Roofers' Pension Fund case and the Wilson case under the Roofers' Pension Fund case number. In February 2017, the court selected the lead plaintiffs for the consolidated case and the lead counsel to the putative class. In March 2017, the court entered a scheduling order. On June 21, 2017, the court-appointed lead plaintiffs filed an amended complaint that superseded the original complaints in the Roofers’ Pension Fund case and the Wilson case. The lead plaintiffs seek to represent a class of shareholders for the period April 21, 2015 through May 3, 2017, and the amended complaint identifies three subclasses - shareholders who purchased shares during the period on the U.S. exchanges; shareholders who purchased shares during the period on the Tel Aviv exchange; and shareholders who owned shares on the final day of the Mylan tender offer November 13, 2015. The amended complaint names as defendants us and 11 current or former directors and officers of Perrigo (Mses. Judy Brown, Laurie Brlas, Jacqualyn Fouse, Ellen Hoffing, and Messrs. Joe Papa, Marc Coucke, Gary Cohen, Michael Jandernoa, Gerald Kunkle, Herman Morris, and Donal O’Connor). The amended complaint alleges violations of Securities Exchange Act sections 10(b) (and Rule 10b 5) and 14(e) against all defendants and 20(a) control person liability against the 11 individuals. In general, the allegations concern the actions taken by us and the former executives to defend against the unsolicited takeover bid by Mylan in the period from April 21, 2015 through November 13, 2015 and the allegedly inadequate disclosure throughout the entire class period related to purported integration problems related to the Omega acquisition, alleges incorrect reporting of organic growth at the Company and at Omega, alleges price fixing activities with respect to six generic prescription pharmaceuticals, and alleges improper accounting for the Tysabri® royalty stream. The amended complaint does not include an estimate of damages. In August 2017, the defendants filed motions to dismiss the amended complaint. The plaintiffs filed their opposition in October 2017. The defendants filed replies in support of the motions to dismiss in November 2017. The court has not indicated whether there will be oral argument of the motions or whether the court will decide the motions on the papers. We intend to defend the lawsuit vigorously. On November 1, 2017, Carmignac Gestion, S.A., filed a securities lawsuit against us and three individuals (former Chairman and CEO Joseph Papa, former CFO Judy Brown, and former Executive Vice President and Board member Marc Coucke). This lawsuit is not a securities class action. The case is styled Carmignac Gestion, S.A. v. Perrigo Company plc, et al., and was filed in the U.S. District Court for the District of New Jersey. The complaint asserts claims under Securities Exchange Act sections 10(b) (and Rule 10b-5), 14(e), and 18 against all defendants as well as 20(a) control person liability against the individual defendants. In general, the plaintiff’s allegations focus on events during the period from April 2015 through April 2016. Plaintiff contends that the defendants provided inadequate disclosure throughout the period concerning the valuation and integration of Omega, the financial guidance provided by us during that period, our reporting about the generic prescription pharmaceutical business and its prospects, and the activities surrounding the efforts to defeat the Mylan tender offer during 2015. Many of the allegations in this case overlap with the allegations of the June 2017 amended complaint in the Roofers’ Pension Fund case described above. The plaintiff does not provide an estimate of damages. We intend to defend the lawsuit vigorously. The parties jointly requested that the court stay this case pending the outcome of a ruling on the motions to dismiss filed in the Roofers' Pension Fund case (discussed above), and the court granted the stay motion. On January 16, 2018, Manning & Napier Advisors, LLC filed a securities lawsuit against us and three individuals (former Chairman and CEO Joseph Papa, former CFO Judy Brown, and former Executive Vice President and Board member Marc Coucke). This lawsuit is not a securities class action. The case is styled Manning & Napier Advisors, LLC v. Perrigo Company plc, et al., and was filed in the U.S. District Court for the District of New Jersey. The complaint asserts claims under Securities Exchange Act sections 10(b) (and Rule 10b-5) and 18 against all defendants as well as 20(a) control person liability against the individual defendants. In general, the plaintiff’s allegations focus on events during the period from April 2015 through May 2017. Plaintiff contends that the defendants provided inadequate disclosure at various times during the period concerning valuation and integration of Omega, the financial guidance provided by us during that period, alleged price fixing activities with respect to six generic prescription pharmaceuticals, and alleged improper accounting for the Tysabri® financial asset. Many of the allegations in this case overlap with the allegations of the June 2017 amended complaint in the Roofers' Pension Fund case described above. The plaintiff does not provide an estimate of damages. We intend to defend the lawsuit vigorously. The parties jointly requested that the court stay this case pending the outcome of a 167 Perrigo Company plc - Item 8 Note 16 ruling on the motion to dismiss filed in the Roofers' Pension Fund case (discussed above), and the court granted the stay motion. On January 26, 2018, two different plaintiff groups (the Mason Capital group and the Pentwater group) each filed a lawsuit against us and the same individuals who are defendants in the amended complaint in the securities class action case described above (Roofers’ Pension Fund case). The same law firm represents these two plaintiff groups, and the two complaints are substantially similar. These two cases are not securities class actions. One case is styled Mason Capital L.P., et al. v. Perrigo Company plc, et al., and was filed in the U.S. District Court for the District of New Jersey. The other case is styled Pentwater Equity Opportunities Master Fund Ltd., et al. v. Perrigo Company plc, et al., and also was filed in the U.S. District Court for the District of New Jersey. Both cases are assigned to the same federal judge that is hearing the class action case and the other individual cases described above (Carmignac and Manning & Napier). Each complaint asserts claims under Securities Exchange Act sections 14(e) (related to tender offer disclosures) against all defendants as well as 20(a) control person liability against the individual defendants. In general, the plaintiff’s allegations describe events during the period from April 2015 through May 2017. Plaintiff contends that the defendants provided inadequate disclosure during the tender offer period in 2015 and point to disclosures at various times during the period concerning valuation and integration of Omega, the financial guidance provided by us during that period, alleged price fixing activities with respect to six generic prescription pharmaceuticals, and alleged improper accounting for the Tysabri® financial asset. Many of the factual allegations in these two cases overlap with the allegations of the June 2017 amended complaint in the Roofers' Pension Fund case described above and the allegations in the Carmignac case described above. The plaintiff does not provide an estimate of damages. The parties to each case jointly requested that the court stay each case pending the outcome of a ruling on the motions to dismiss filed in the Roofers’ Pension Fund case (discussed above). The court granted the stay motion in each case. We intend to defend both lawsuits vigorously. On February 13, 2018, a group of plaintiff investors affiliated with Harel Insurance Investments & Financial Services, Ltd. filed a lawsuit against us and the same individuals who are defendants in the amended complaint in the securities class action case described above (Roofers’ Pension Fund case). The new complaint is substantially similar to the amended complaint in the Roofers' Pension Fund case. The relevant period in the new complaint stretches from February 2014 to May 2, 2017. The complaint adds as defendants two individuals who served on our Board prior to 2016. The case is styled Harel Insurance Company, Ltd., et al. v. Perrigo Company plc, et al., and was filed in the U.S. District Court for the District of New Jersey and is assigned to the same federal judge that is hearing the class action cases and the four other individual cases described above (Carmignac, Manning & Napier, Mason Capital, and Pentwater). The Harel Insurance Company complaint asserts claims under Securities Exchange Act section 10(b) (and related SEC Rule 10b 5) and section 14(e) (related to tender offer disclosures) against all defendants as well as 20(a) control person liability against the individual defendants. The complaint also asserts claims based on Israeli securities laws. In general, the plaintiff’s allegations describe events during the period from February 2014 through May 2017. Plaintiff contends that the defendants provided inadequate disclosure during the tender offer events in 2015 and point to disclosures at various times during the period concerning valuation and integration of Omega, the financial guidance provided by us during that period, alleged price fixing activities with respect to six generic prescription pharmaceuticals, and alleged improper accounting for the Tysabri® financial asset from February 2014 until the withdrawal of past financial statements in April 2017. Many of the factual allegations in these two cases overlap with the allegations of the June 2017 amended complaint in the Roofers' Pension Fund case described above and the allegations in the four opt out cases also described above. The plaintiff does not provide an estimate of damages. The parties jointly filed a stay motion similar to the stay sought in the five other opt out cases. The court granted the stay motion. We intend to defend the lawsuit vigorously. On February 16, 2018, First Manhattan Company filed a securities lawsuit against us and three individuals (former Chairman and CEO Joseph Papa, former CFO Judy Brown, and former Executive Vice President and Board member Marc Coucke). This lawsuit is not a securities class action. The case is styled First Manhattan Co. v. Perrigo Company plc, et al., and was filed in the U.S. District Court for the District of New Jersey. The case was assigned to the same judge hearing the class action case and the five other opt out cases. The complaint asserts claims under Securities Exchange Act sections 10(b) (and Rule 10b-5), 14(e), and 18 against all defendants as well as 20(a) control person liability against the individual defendants. In general, the plaintiff’s allegations focus on events during the period from April 2015 through May 2017. Plaintiff contends that the defendants provided inadequate disclosure at various times during the period concerning valuation and integration of Omega, the financial guidance provided by us during that period, alleged price fixing activities with respect to six generic prescription pharmaceuticals, and alleged improper accounting for the Tysabri® financial asset. This lawsuit was 168 Perrigo Company plc - Item 8 Note 16 filed by the same law firm that filed the Manning & Napier Advisors case and the Carmignac case described above and generally makes the same factual assertions as in the Manning & Napier Advisors case. Many of the allegations in this case overlap with the allegations of the June 2017 amended complaint in the Roofers' Pension Fund case described above. The plaintiff does not provide an estimate of damages. We intend to defend the lawsuit vigorously. The parties jointly requested that the court stay this case pending the outcome of a ruling on the motions to dismiss filed in the Roofers’ Pension Fund case (discussed above). The court granted the stay motion. In Israel Because our shares are traded on the Tel Aviv exchange under a dual trading arrangement, we are potentially subject to securities litigation in Israel. Three cases were filed; two were voluntarily dismissed and one was stayed. We are consulting Israeli counsel about our response to these allegations and we intend to defend these cases vigorously. On May 22, 2016, shareholders filed a securities class action against us and five individual defendants: Our former CEO Mr. Papa, our former Executive Vice President and General Manager of the BCH segment Marc Coucke, our then Chief Executive Officer John Hendrickson, our former Board member Gary Kunkle, Jr., and our Board member Laurie Brlas alleging violations of Israeli law in the District Court of Tel Aviv-Jaffa (Schweiger et al. v. Perrigo Company plc, et al.). On June 15, 2016, we filed a motion to stay the case pending the outcome of the securities class action pending in the New Jersey Federal Court. The plaintiffs did not oppose the motion. The Israeli court granted the motion on the same day, and the Schweiger action was stayed. In October 2017, the Schweiger plaintiffs dismissed their claims without prejudice because of the pendency of another class action case filed in Israel (see discussion below of the Israel Elec. Corp. Employees’ Educ. Fund case). The court approved the voluntary dismissal. On March 29, 2017, plaintiff Eyal Keinan commenced an action in the District Court of Tel Aviv-Jaffa asserting securities claims against two defendants: Perrigo and its auditor Ernst & Young LLP ("EY"). The case is styled Keinan v. Perrigo Company plc, et al. The action sought certification of a class of purchasers of Perrigo shares on the Israeli exchange beginning February 6, 2014. The proposed closing date for the class was not clear from the complaint though it appeared to extend into 2017. In general, the plaintiff asserted that we improperly accounted for our stream of royalty income from two drugs: Tysabri® and Prialt. The court filings contended that the alleged improper accounting caused the audited financial results for Perrigo to be incorrect for the six month period ended December 31, 2015, and the years ended June 27, 2015 and June 28, 2014 and the other financial data released by us over those years and 2016 to also be inaccurate. The plaintiff maintained that the defendants are liable under Israeli securities law or, in the alternative, under U.S. securities law. The plaintiff indicated an initial, preliminary class damages estimate of 686.0 million NIS (approximately $192.0 million at 1 NIS = $0.28 cent). In January 2018, the Keinan plaintiff announced its intention to dismiss his claims because of the pendency of another class action case filed in Israel (see discussion below of the Israel Elec. Corp. Employees’ Educ. Fund case). The court granted the dismissal on February 11, 2018. On June 28, 2017, a plaintiff filed a complaint in Tel Aviv District Court styled Israel Elec. Corp. Employees’ Educ. Fund v. Perrigo Company plc, et al. The lead plaintiff seeks to represent a class of shareholders who purchased Perrigo stock on the Tel Aviv exchange during the period April 24, 2015 through May 3, 2017 and also a claim for those that owned shares on the final day of the Mylan tender offer (November 13, 2015). The amended complaint names as defendants the Company, EY (the Company’s auditor), and 11 current or former directors and officers of Perrigo (Mses. Judy Brown, Laurie Brlas, Jacqualyn Fouse, Ellen Hoffing, and Messrs. Joe Papa, Marc Coucke, Gary Cohen, Michael Jandernoa, Gerald Kunkle, Herman Morris, and Donal O’Connor). The complaint alleges violations under U.S. securities laws of Securities Exchange Act sections 10(b) (and Rule 10b 5) and 14(e) against all defendants and 20(a) control person liability against the 11 individuals or, in the alternative, under Israeli securities laws. In general, the allegations concern the actions taken by us and our former executives to defend against the unsolicited takeover bid by Mylan in the period from April 21, 2015 through November 13, 2015 and the allegedly inadequate disclosure concerning purported integration problems related to the Omega acquisition, alleges incorrect reporting of organic growth at the Company, alleges price fixing activities with respect to six generic prescription pharmaceuticals, and alleges improper accounting for the Tysabri® royalty stream. The plaintiff indicates an initial, preliminary class damages estimate of 2.7 billion NIS (approximately $760.0 million at 1 NIS = $0.28 cent). We intend to defend the lawsuit vigorously. 169 Perrigo Company plc - Item 8 Note 16 On July 12, 2017, the plaintiff in the Israel Elec. Corp. Employees’ Educ. Fund v. Perrigo Company plc, et al. case filed a motion to have all three cases pending in Israel either consolidated or the other two cases dismissed so that the Israel Elec. Corp. Educ. Fund plaintiff can proceed as the sole plaintiff. In October 2017, the Schweiger plaintiffs (see description above) voluntarily dismissed their securities class action without prejudice as part of their response to the motion filed by the Israel Elec. Corp. Educ. Fund plaintiff. A variety of other procedural motions were also pending having to do with the timing of any response by defendants. The court held an initial conference on November 9, 2017 to address the motion filed by the Israel Elec. Corp. Educ. Fund plaintiff. Subsequently, the competing class plaintiffs held discussions and informed the court in January 2018 that they had reached an agreement among themselves such that the Education Fund case will continue while the Keinan plaintiff will dismiss its case. The court approved this outcome. At the request of the parties, the court has stayed the Education Fund case pending the final adjudication of the class action case in DNJ (the Roofers’ Pension Fund case described above under Securities Litigation In the United States). The court approved the stay. Eltroxin During October and November 2011, nine applications to certify a class action lawsuit were filed in various courts in Israel related to Eltroxin, a prescription thyroid medication manufactured by a third party and distributed in Israel by our subsidiary, Perrigo Israel Agencies Ltd. The respondents included our subsidiaries, Perrigo Israel Pharmaceuticals Ltd. and/or Perrigo Israel Agencies Ltd., the manufacturers of the product, and various healthcare providers who provide healthcare services as part of the compulsory healthcare system in Israel. One of the applications was dismissed and the remaining eight applications were consolidated into one application. The applications arose from the 2011 launch of a reformulated version of Eltroxin in Israel. The consolidated application generally alleges that the respondents (a) failed to timely inform patients, pharmacists and physicians about the change in the formulation; and (b) failed to inform physicians about the need to monitor patients taking the new formulation in order to confirm patients were receiving the appropriate dose of the drug. As a result, claimants allege they incurred the following damages: (a) purchases of product that otherwise would not have been made by patients had they been aware of the reformulation; (b) adverse events to some patients resulting from an imbalance of thyroid functions that could have been avoided; and (c) harm resulting from the patients' lack of informed consent prior to the use of the reformulation. Several hearings on whether or not to certify the consolidated application took place in December 2013 and January 2014. On May 17, 2015, the District Court certified the motion against Perrigo Israel Agencies Ltd. and dismissed it against the remaining respondents, including Perrigo Israel Pharmaceuticals Ltd. On June 16, 2015, we submitted a motion for permission to appeal the decision to certify to the Israeli Supreme Court together with a motion to stay the proceedings of the class action until the motion for permission to appeal is adjudicated. We have filed our statement of defense to the underlying proceedings. The parties are currently engaged in mediation in an attempt to settle the matter. The underlying proceedings have been stayed pending the outcome of the mediation process and, if necessary, a decision on the motion to appeal. On November 14, 2017 the Parties submitted the agreed settlement agreement to the approval of the Supreme Court, which referred the approval back to the District Court. During three hearings that took place on November 29, 2017, December 13, 2017 and January 11, 2018 the District Court opined that it would approve the settlement agreement subject to certain amendments to be proposed by the Court (which would not impact the monetary settlement reached) and set a hearing for January 30, 2018 to discuss and finalize the proposed changes. Meanwhile, the Court ordered the settlement to be (1) provided to the Attorney General for review (standard procedure); and (2) published in the written media (newspapers), to enable the class members to submit any objections or “opt-out” to the proposed settlement by February 15, 2018. On February 21, 2018, the District Court held a hearing to, among others, review objections received from class members who had notified the District Court of their desire to opt out of the settlement. In addition, a representative of the Israeli Attorney General’s office notified the District Court that, based upon their preliminary examination of the settlement, they intend to object to the settlement in its current form. The District Court recommended that the parties continue to discuss and minimize objections to the settlement and scheduled another hearing for May 13, 2018. 170 Perrigo Company plc - Item 8 Note 16 Tysabri® Product Liability Lawsuits We and our collaborator Biogen are co-defendants in product liability lawsuits arising out of the occurrence of Progressive Multifocal Leukoencephalopathy, a serious brain infection, and serious adverse events, including deaths, which occurred in patients taking Tysabri®. Each co-defendant would be responsible for 50% of losses and expenses arising out of any Tysabri® product liability claims. During calendar year 2016, one case in the U.S. was settled and two others were dismissed with prejudice. In 2017, seven other cases were dismissed with prejudice. While we intend to vigorously defend the remaining lawsuits, management cannot predict how these cases will be resolved. Adverse results in one or more of these lawsuits could result in substantial judgments against us. Claim Arising from the Omega Acquisition On December 16, 2016, we and Perrigo Ireland 2 brought an arbitral claim ("Claim") against Alychlo NV ("Alychlo") and Holdco I BE NV ("Holdco") (together the Sellers) in accordance with clause 26.2 of the Share Purchase Agreement dated November 6, 2014 ("SPA") and the rules of the Belgian Centre for Arbitration and Mediation ("CEPANI"). Our Claim relates to the accuracy and completeness of information about Omega provided by the Sellers as part of the sale process, the withholding of information by the Sellers during that process and breaches of Sellers’ warranties. We are seeking monetary damages from the Sellers. The Sellers served their respective responses to the Claim on February 20, 2017. In its response, Alychlo has asserted a counterclaim for monetary damages contending that we breached the duty of good faith in performing the SPA. There can be no assurance that our Claim will be successful, and Sellers deny liability for the Claim. We deny that Alychlo is entitled to any relief (including monetary relief) under the counterclaim. The arbitration proceedings are confidential as required by the SPA and the rules of the CEPANI. NOTE 17 - COLLABORATION AGREEMENTS AND OTHER CONTRACTUAL ARRANGEMENTS We actively collaborate with other pharmaceutical companies to develop, manufacture and market certain products or groups of products. These types of agreements are common in the pharmaceutical industry. We may choose to enter into these types of agreements to, among other things, leverage our or others’ scientific research and development expertise or utilize our extensive marketing and distribution resources. Terms of the various collaboration agreements may require us to make or receive milestone payments upon the achievement of certain product research and development objectives and pay or receive royalties on the future sale, if any, of commercial products resulting from the collaboration. Milestone and up-front payments made are generally recorded in research and development expense if the payments relate to drug candidates that have not yet received regulatory approval. Milestone and up-front payments made related to approved drugs will generally be capitalized and amortized to cost of goods sold over the economic life of the product. Royalties received are generally reflected as revenues, and royalties paid are generally reflected as cost of goods sold. We enter into a number of collaboration agreements in the ordinary course of business. Although we do not consider these arrangements to be material, the following is a brief description of notable agreements entered into during the years ended December 31, 2016 and June 27, 2015. We did not enter into any collaborative arrangements during the the six months ended December 31, 2015. Year Ended December 31, 2017 In December 2017, we entered into a collaboration agreement with a generic pharmaceutical development company, pursuant to which the parties will collaborate in the ongoing development and commercialization of a generic injectable product. We will provide assistance including preparing and filing the product ANDA, and be responsible for commercializing the product. As part of the agreement, we paid a $2.5 million milestone payment on the effective date of the agreement. The $2.5 million fee is reported in Research and development on the consolidated financial statements. We will make additional payments if regulatory approval is obtained and certain other development milestones are achieved. These contingent milestone payments could total $14.5 million in aggregate. There can be no assurance that any such products will be approved by the FDA on the anticipated schedule or at all. 171 Perrigo Company plc - Item 8 Note 17 Year Ended December 31, 2016 During the year ended December 31, 2016, we added three additional products to the May 15, 2015 development agreement discussed below that are subject to similar buy-back terms if the products are approved by the FDA. We did not receive any consideration from the clinical stage development company, nor do we expect to incur any expense related to the development of the additional products. The estimated purchase price for these additional products, based on the initial development budget, is approximately $126.0 million. If development costs exceed the initial budgeted amounts, the purchase price will increase, but will not exceed approximately $174.0 million. If the products are approved by the FDA and we purchase the products, we estimate that one of the acquisitions will occur in 2019 and two of the acquisitions will occur in 2021. There can be no assurance that any such products will be approved by the FDA on the anticipated schedule or at all. Year Ended June 27, 2015 On May 15, 2015, we entered into a development agreement wherein we transferred the ownership rights to two pharmaceutical products to a clinical stage development company to fund and conduct development activities for the products. We do not expect to incur any expense related to the development of either product. If the products are approved by the FDA, we will execute a buy-back agreement to purchase each product for a multiple of the development costs incurred. Based on the initial development budget for each product, the estimated purchase price for both products is approximately $78.0 million. If development costs exceed the initial budgeted amounts, the purchase price will increase but will not exceed approximately $105.0 million. If the products are approved by the FDA and we purchase the products, we estimate the acquisitions will occur in 2019. On May 1, 2015, we entered into an agreement with a clinical stage biotechnology company for the development of two specialty pharmaceutical products. We paid $18.0 million for an option to acquire the two products, which we reported in research and development expense. On March 1, 2016, we exercised the purchase option to acquire both products. We will make additional payments if we obtain regulatory approval and achieve certain sales milestones, and these contingent milestone payments could total $30.0 million in aggregate. We will also be obligated to make certain royalty payments over periods ranging from seven to ten years from the launch of each product (refer to the Development-Stage Rx Products acquisition in Note 2 for additional information regarding the acquisition). In addition, on December 20, 2017, we divested one of the development-stage Rx products (refer to Note 2 for additional information on the divestment. Additional future milestone payments and receipts related to agreements not specifically discussed above are not material. 172 NOTE 18 - RESTRUCTURING CHARGES We periodically take action to reduce redundant expenses and improve operating efficiencies, typically in connection with business acquisitions. The following reflects our restructuring activity (in millions): Perrigo Company plc - Item 8 Note 18 Balance at June 28, 2014 $ Additional charges Payments Non-cash adjustments Balance at June 27, 2015 Additional charges Payments Non-cash adjustments Balance at December 31, 2015 Additional charges Payments Non-cash adjustments Balance at December 31, 2016 Additional charges Payments Non-cash adjustments Balance at December 31, 2017 $ 16.4 5.1 (18.5) (1.4) 1.6 26.9 (6.4) (1.4) 20.7 31.0 (35.8) 3.8 19.7 61.0 (59.6) 0.3 21.4 Restructuring activity includes severance, lease exit costs, and asset impairments. The charges incurred during the six months ended December 31, 2015 and the year ended December 31, 2016 were primarily associated with actions we took to streamline our organization as announced on October 22, 2015. The charges incurred during the year ended December 31, 2017 were primarily associated with actions we took to streamline our organization as announced on February 21, 2017. During the year ended December 31, 2017, $61.0 million of restructuring expenses were recorded, $27.4 million of which was recorded in our CHCA segment and $17.1 million in our CHCI segment. There were no other material restructuring programs that impacted any other one reportable segment for the year ended December 31, 2017. During the year ended December 31, 2016, $31.0 million of restructuring expenses were recorded, $20.9 million of which was recorded in our CHCI segment. There were no other material restructuring programs in any of the periods presented. All charges are recorded in Restructuring expense. The remaining $17.6 million liability for employee severance benefits will be paid within the next year, while the remaining $3.8 million liability for lease exit costs will be incurred over the remaining terms of the applicable leases. NOTE 19 - SEGMENT AND GEOGRAPHIC INFORMATION Our segment reporting structure is consistent with the way our chief operating decision maker makes operating decisions, allocates resources and manages the growth and profitability of the business. Operating segments with similar economic characteristics, including long-term profitability, nature of the products sold and production processes, distribution methods, and classes of customers, are aggregated as reportable segments (refer to Note 1). 173 Perrigo Company plc - Item 8 Note 19 We generated third-party revenue in the following geographic locations(1) during each of the periods presented below (in millions): Ireland U.S. Europe All other countries(2) Year Ended Six Months Ended December 31, 2017 December 31, 2016 December 31, 2015 Year Ended June 27, 2015 $ $ 30.4 $ 89.1 $ 11.4 $ 3,272.3 1,313.2 330.3 3,353.0 1,493.0 345.5 1,686.2 758.2 176.4 7.2 3,303.2 576.4 340.3 4,946.2 $ 5,280.6 $ 2,632.2 $ 4,227.1 (1) (2) The net sales by geography is derived from the location of the entity that sells to a third party.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE Not applicable. ITEM 9A. CONTROLS AND PROCEDURES (a) Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) 178 Perrigo Company plc - Item 9A or 15d-15(e) of the Exchange Act) as of December 31, 2017. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of December 31, 2017 because of the material weakness in our internal control over financial reporting described in the "Management's Annual Report on Internal Control over Financial Reporting." Notwithstanding this material weakness, management concluded that the consolidated financial statements included in this Annual Report present fairly, in all material respects, the financial position of the Company at December 31, 2017 in conformity with GAAP and our external auditors have issued an unqualified opinion on our consolidated financial statements as of and for the year ended December 31, 2017. (b) Management’s Annual Report on Internal Control Over Financial Reporting MANAGEMENT’S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING The management of Perrigo Company plc is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles and includes those policies and procedures that: • Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; • Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and • Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. All systems of internal control, no matter how well designed, have inherent limitations. Therefore, even those systems deemed to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Because of inherent limitations, our internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2017. The framework used in carrying out our evaluation was the 2013 Internal Control - Integrated Framework published by the Committee of Sponsoring Organizations ("COSO") of the Treadway Commission. In evaluating our information technology controls, we also used components of the framework contained in the Control Objectives for Information and related Technology ("COBIT"), which was developed by the Information Systems Audit and Control Association’s IT Governance Institute, as a complement to the COSO internal control framework. Management has concluded that our internal control over financial reporting was ineffective as of December 31, 2017. The results of management’s assessment have been reviewed with our Audit Committee. 179 Perrigo Company plc - Item 8 Income Taxes The material weaknesses over the income tax process that was identified during our fiscal year ended December 31, 2016 was not remediated during our fiscal year ended December 31, 2017, and we determined that we did not design or maintain effective controls over our income tax accounting process. Accordingly, there is a reasonable possibility that a material misstatement will not be prevented or detected on a timely basis. The results of management’s assessment have been reviewed with our Audit Committee. Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this Annual Report on Form 10-K, also audited the effectiveness of our internal control over financial reporting, as stated in their report that is included herein. REMEDIATION PLAN We are committed to remediating the control deficiencies that gave rise to the material weakness described above. Management is responsible for implementing changes and improvements to internal control over financial reporting and for remediating the control deficiencies that gave rise to the material weakness. With oversight from the Audit Committee, we have taken significant steps to remediate our internal control deficiencies in income taxes by redesigning our controls, many of which operated for the first time at December 31, 2017. Our efforts have consisted primarily of strengthening our tax organization and designing a suite of controls related to the components of our income tax process, including valuation allowances, uncertain tax positions and non-routine events and transactions, to enhance our management review controls over income taxes. Because many of our controls operated for the first time at December 31, 2017, we have not had a sufficient period of time to demonstrate operating effectiveness in 2017. Some of the key remediation actions taken include: • Reviewing our income tax processes and controls and enhancing the overall design and procedures performed in calculating our income tax provision on an interim and annual basis • Significantly strengthening our tax capabilities through a combination of key new hires and providing additional resources • Re-designing our management review controls and enhancing the precision of review around the key income tax areas To complete the remediation, we plan, with oversight from the Audit Committee, to continue to: • Evaluate the sufficiency of our income tax resources and personnel to determine whether additional enhancements are needed • Evaluate whether further enhancements are needed to the design of our income tax procedures and controls • Demonstrate consistent operating effectiveness of our management review controls over income taxes over a number of quarterly periods We expect to implement the remaining remediation actions in 2018. Until the remediation actions are fully implemented and the operational effectiveness of related internal controls is validated through testing, the material weakness described above will continue to exist. We are committed to achieving and maintaining a strong internal control environment and believe the remediation measures will strengthen our internal control over financial reporting and remediate the material weakness identified. (c) Changes in Internal Control over Financial Reporting Other than as described above under "Remediation Plan for Material Weakness," there have been no changes in our internal control over financial reporting during the three months ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 180 Perrigo Company plc - Item 8 181 ITEM 9B. OTHER INFORMATION Not applicable. 182 Perrigo Company plc - Item 8 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL REPORTING To the Shareholders and the Board of Directors of Perrigo Company plc Opinion on Internal Control Over Financial Reporting We have audited Perrigo Company plc’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria, Perrigo Company plc (the Company) has not maintained effective internal control over financial reporting as of December 31, 2017, based on the COSO criteria. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. Management has identified a material weakness in controls related to the company’s income tax accounting process. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2017, 2016 and 2015, the related consolidated statements of operations, comprehensive income (loss), shareholders' equity and cash flows for each of the years ended December 31, 2017 and 2016, the period from June 28, 2015 to December 31, 2015, and the fiscal year ended June 27, 2015, and the related notes and the financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”). This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2017 consolidated financial statements, and this report does not affect our report dated March 1, 2018, which expressed an unqualified opinion thereon. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance 183 Perrigo Company plc - Item 8 with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ Ernst & Young LLP Grand Rapids, Michigan March 1, 2018 184 Perrigo Company plc - Item 10 PART III.
