You should read the following discussion and analysis of the results of operations of the Company and its subsidiaries in conjunction with our unaudited consolidated financial statements and related notes contained elsewhere in this report and our disclosures and discussions in our consolidated financial statements for the year ended December 31, 2019 prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB"), using the euro as our reporting currency.

The term "North America Segment" refers to our North America operating segment, the term "EMEA Segment" refers to the Europe, Middle East and Africa operating segment, the term "Asia-Pacific Segment" refers to our Asia-Pacific operating segment, and the term "Latin America Segment" refers to our Latin America operating segment. The term "Corporate" includes certain headquarters' overhead charges, including accounting and finance, centrally managed production, asset management, quality management, procurement and research and development. The abbreviation "M" is used to denote the presentation of amounts in millions. The term "Constant Currency" or at "Constant Exchange Rates" means that we have translated local currency revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items for the current reporting period into euro using the prior year exchange rates to provide a comparable analysis without effect from exchange rate fluctuations on translation, as described below under "Financial condition and results of operations—II. Discussion of measures—Non-IFRS measures."

Forward-looking statements

This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). When used in this report, the words "outlook," "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" and similar expressions are generally intended to identify forward looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, forward-looking statements are inherently subject to risks and uncertainties, many of which cannot be predicted with accuracy and some of which might not even be anticipated, and future events and actual results, financial and otherwise, could differ materially from those set forth in or contemplated by the forward-looking statements contained elsewhere in this report. We have based these forward-looking statements on current estimates and assumptions made to the best of our knowledge. By their nature, such forward-looking statements involve risks, uncertainties, assumptions and other factors which could cause actual results, including our financial condition and profitability, to differ materially, positively or negatively, relative to the results expressly or implicitly described in or suggested by these statements. Moreover, forward-looking estimates or predictions derived from third parties' studies or information may prove to be inaccurate. Consequently, we cannot give any assurance regarding the future accuracy of the opinions set forth in this report or the actual occurrence of the projected developments described herein. In addition, even if our future results meet the expectations expressed here, those results may not be indicative of our performance in future periods.

These risks, uncertainties, assumptions, and other factors, including associated costs, could cause actual results to differ from our projected results and include, among others, the following:

•

changes in governmental and commercial insurer reimbursement for our complete products and services portfolio, including the United States ("U.S.") Medicare reimbursement system for dialysis and other health care services, including potentially significant changes to the Patient Protection and Affordable Care Act of 2010 (Pub.L. 111-148), as amended by the Health Care and Education Reconciliation Act (Pub.L. 111-152) (collectively, "ACA") that could be enacted due to the announced intention of the Trump administration to continue its efforts to repeal and replace the ACA or result from pending legal challenges to the ACA;

•

the outcome of government and internal investigations as well as litigation;

•

risks relating to compliance with current and future government regulations applicable to our business including sanctions and export control laws and regulations, the impact of health care, tax and trade law reforms and regulation as well as, in the U.S., the Anti-Kickback Statute, the False Claims Act, the

the influence of commercial insurers and integrated care organizations, including efforts by these organizations to manage costs by limiting health care benefits, reducing provider reimbursement and/or restricting options for patient funding of health insurance premiums;

•

product liability risks;

•

risks relating to our ability to continue to make acquisitions, including our ability to develop our core dialysis business to increase future growth and product sales;

•

risks relating to our ability to attract and retain skilled employees, including shortages of skilled clinical personnel, and risks that legislative, union, or other labor-related activities or changes will result in significant increases in our operating costs or decreases in productivity;

•

the impact of currency and interest rate fluctuations;

•

potential impairment of our goodwill, investments or other assets due to decreases in the recoverable amount of those assets relative to their book value, particularly as a result of sovereign rating agency downgrades;

•

our ability to protect our information technology systems against cyber security attacks or prevent other data privacy or security breaches;

•

changes in our costs of purchasing and utilization patterns for pharmaceuticals as well as changes in raw material and energy costs or the inability to procure raw materials;

•

launch of new technology, advances in medical therapies, or new market entrants that compete with our medical businesses;

•

potential increases in tariffs and trade barriers that could result from withdrawal by single or multiple countries from multilateral trade agreements or the imposition of retaliatory tariffs and other countermeasures in the wake of trade disputes;

•

collectability of our receivables, which depends primarily on the efficacy of our billing practices and the financial stability and liquidity of our governmental and commercial payors;

•

our ability to achieve cost savings in various health care risk management programs in which we participate or intend to participate;

•

the greater size, market power, experience and product offerings of certain competitors in certain geographic regions and business lines;

Important factors that could contribute to such differences are noted in the "Supplemental Risk Factors" set forth below, "Financial condition and results of operations—I. Overview" below, in note 8 of the notes to consolidated financial statements (unaudited) included in this report, in note 22 of the notes to consolidated financial statements included in our Annual Report on Form 20-F for the year ended December 31, 2019, as well as under "Risk Factors," "Business overview," "Operating and financial review and prospects," and elsewhere in that report.

Our business is also subject to other risks and uncertainties that we describe from time to time in our public filings. Developments in any of these areas could cause our results to differ materially from the results that we or others have projected or may project.

Our reported financial condition and results of operations are sensitive to accounting methods, assumptions and estimates that are the basis of our financial statements. The actual accounting policies, the judgments made in the selection and application of these policies, as well as the sensitivities of reported results to changes in accounting policies, assumptions and estimates, are factors to be considered along with our financial statements and the discussion under "Results of operations, financial position and net assets" below.

Rounding adjustments applied to individual numbers and percentages shown in this and other reports may result in these figures differing immaterially from their absolute values.

Supplemental risk factors

As a result of the current global economic climate, specifically as it relates to COVID-19, we are subject to additional risks, and we have updated previously disclosed risks, related to the on-going worldwide crisis described below. We are, and will continue to be, subject to the risks described in our Annual Report on Form 20-F for the year ended December 31, 2019 (our "2019 Form 20-F"), specifically under "Risk Factors," and the supplemental risk factors described below should be read in conjunction with those risk factors.

We are subject to risks associated with public health crises and epidemics/pandemics, such as the global spread of the COVID-19 pandemic which may result in increased costs and restrictions on our business activities and the business activities of our suppliers and our customers, resulting in a material adverse effect on our business, results of operations and financial condition.

Our global operations expose us to risks associated with public health crises and epidemics/pandemics, such as the rapid global spread of the COVID-19 pandemic. COVID-19 has resulted in a material deterioration of the conditions for the global economy and financial markets have been materially affected which may, as a result, adversely affect our business, results of operations and financial condition. While the financial impact of COVID-19 on us has not been significant to date, it is currently impossible to estimate or quantify the extent of its prospective negative effects on our business, results of operations and financial condition. The COVID-19 pandemic may have an adverse impact on our operations, manufacturing, supply chains and distribution channels and increase our expenses, including as a result of impacts associated with preventive and precautionary measures that we, our suppliers, customers and other businesses or governments impose on a local, regional, national or international level. Due to these impacts and measures, we are incurring incremental expenses to provide care to our patients and we are experiencing both reductions and increases in demand for certain of our products as health care customers re-prioritize the treatment of patients. We expect to continue to experience significant and unpredictable expenses, reductions and increases in the immediately foreseeable future. In addition to existing travel restrictions, countries may continue to close borders, restrict certain product flows, impose prolonged quarantines and further restrict travel, which may significantly impact the ability of our employees to produce products or provide services, or may significantly hamper our products from moving through the supply chain.

In addition to the effects on our health care products business, given the already compromised health condition of our typical dialysis patients, our patients represent a heightened at-risk population, particularly during a public health crisis, such as the COVID-19 outbreak. Our in-center and home patients must receive their life-saving dialysis treatment several days a week for three to four hours at a time, which presents a unique challenge for patients and their care teams. We must ensure that there are enough clinical staff, including nurses, social workers, dietitians, care technicians and available space to treat all of our patients, including those who are or may be infected with COVID-19, in a manner that does not unnecessarily expose our care teams or other patients for whom we provide dialysis services. We have

3

incurred, and expect to continue to incur, extra costs in establishing isolated treatment areas for COVID-positive and suspected patients and implementing other precautions as well as incur costs to identify, contain and remedy the impact in the event that a staff member or patient is determined to have developed COVID-19. It appears that COVID-19 has resulted in a significant increase in persons experiencing temporary renal failure, and we could incur additional staffing costs required to meet the resulting increased demand for dialysis treatment and/or to provide equipment and medical staff needed for emergency treatments, for example in hospitals. To the extent that the COVID-19 pandemic increases the historical normal mortality rate in our patient population, our near-term operating results may be materially and adversely affected. COVID-19 has resulted, and may continue to result, in more of our dialysis patients requiring hospitalization, which could also materially and adversely affect our financial results, including those of our value-based and shared risk products and services.

In the US, the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act") has been enacted to mitigate certain adverse financial impacts of the pandemic, including impacts in the health care sector. Additional funding provided under the CARES Act provides some financial support to our business in the U.S. through suspension of the 2% Medicare payment sequestration reduction from May to December 2020, accelerated and advance payments of Medicare reimbursement and grants to defray expenses and mitigate the loss of revenues related to the COVID-19 pandemic. However, these measures may not fully offset potential lost revenues and increased costs. Further legislation and amendments to existing legislation intended to fight the COVID-19 pandemic and its adverse economic consequences can be expected in the markets in which we operate. As the COVID-19 pandemic is prolonged, the risk of further government intervention or measures to counteract the pandemic could impact our business globally. It is currently not possible to estimate or to quantify any effects of such legislative measures on our business.

Furthermore, the outbreak of COVID-19 could disrupt our operations due to absenteeism among our workforce. As a result of these and potentially other factors, and given the rapid and evolving nature of the virus, COVID-19 could negatively affect our results, and it is uncertain how COVID-19 will affect our global operations generally if these impacts persist or are exacerbated over an extended period of time. Any of these impacts could have a material adverse effect on our business, financial condition and results of operations.

Global economic conditions as well as disruptions in financial markets may have an adverse effect on our businesses.

We are dependent on the conditions of the financial markets and the global economy. In order to pursue our business, we are reliant on capital markets, as are our renal product customers and commercial health care insurers. Limited or more expensive access to capital in the financial markets could adversely affect our business and profitability. Among other things, the potential decline in federal and state revenues in an economic slowdown or recession may create additional pressures to contain or reduce reimbursements for our services from public payors around the world, including Medicare, Medicaid in the United States and other government sponsored programs in the United States and other countries around the world.

Devaluation of currencies and worsening economic conditions, including inflationary cost increases in various markets in connection with deteriorating country credit ratings also increase the risk of a goodwill impairment, which could lead to a partial or total goodwill write-off in the affected cash generating units, or have a negative impact on our investments and external partnerships. In addition, uncertainty in the financial markets could adversely affect the variable interest rates payable under our credit facilities or could make it more difficult to obtain or renew such facilities or to obtain other forms of financing in the future as access to these capital markets is restricted. Most recently, the rapid global spread of the COVID-19 pandemic has resulted in a material deterioration of the conditions for the global economy and financial markets have been materially and adversely affected which could have adverse effects on our financial condition and our liquidity.

Job losses or increases in the unemployment rate in the United States may result in a smaller percentage of our patients being covered by employer group health plans and a larger percentage being covered by lower paying Medicare and Medicaid programs. Unemployment rates globally have been impacted by the COVID-19 outbreak, which adversely affected the global economy and could, should the effects continue, result in an economic downturn that may adversely impact our operating results. The extent to which the COVID-19 outbreak impacts our business, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted. To the extent that our commercial payors are negatively impacted by a decline in the economy, including the projected decline

Table of Contents

resulting from the COVID-19 pandemic, we may experience further pressure on commercial rates, a further slowdown in collections and a reduction in the amounts we expect to collect.

Any or all of these factors, or other consequences of the continuation, or worsening, of domestic and global economic conditions which cannot currently be predicted, could continue to have a material adverse effect on our businesses and results of operations.

We could be adversely affected if we experience shortages of goods or material price increases from our suppliers, or an inability to access new and improved products and technology.

Our business is dependent on the reliable supply of several raw materials for production and service purposes. If we are unable to obtain sufficient quantities of these raw materials at times of limited availability of such materials, this could result in delays in production and hence have an adverse effect on our results of operations. Similarly, price increases by suppliers and the inability to access new products or technology could also adversely affect our results of operations.

Our procurement risk mitigation efforts include (i) the development of partnerships with strategic suppliers through framework contracts, (ii) where reasonably practicable, at least two sources for all supply and price-critical primary products (dual sourcing, multiple sourcing), and (iii) measures to prevent loss of suppliers, such as risk analyses as well as continuous supply chain monitoring. Any failure of these measures to mitigate disruptive goods shortages and potential price increases or to allow access to favorable new product and technology developments could have an adverse impact on our business and financial condition.

Measures taken by governmental authorities and private actors to limit the spread of the COVID-19 virus have interfered, and may continue to interfere, with the ability of our employees, suppliers, and other business providers to carry out their assigned tasks or supply materials at ordinary levels of performance. While the financial impact of these actions on us has not been material to date, given the rapid spread and evolving nature of the virus, it is uncertain how COVID-19 will affect our global operations generally if these actions persist or are expanded over an extended period of time.

Financial condition and results of operations

I.     Overview

We are the world's largest kidney dialysis company, based on publicly reported revenue and number of patients treated. We provide dialysis care and related services to persons who suffer from end-stage renal disease ("ESRD") as well as other health care services. We also develop, manufacture and distribute a wide variety of health care products, which includes dialysis and non-dialysis products. Our dialysis products include hemodialysis machines, peritoneal cyclers, dialyzers, peritoneal solutions, hemodialysis concentrates, solutions and granulates, bloodlines, renal pharmaceuticals and systems for water treatment. Our non-dialysis products include acute cardiopulmonary and apheresis products. We supply dialysis clinics we own, operate or manage with a broad range of products and also sell dialysis products to other dialysis service providers. We sell our health care products to customers in around 150 countries and we also use them in our own health care service operations. Our dialysis business is therefore vertically integrated. We describe certain of our other health care services as "Care Coordination." Care Coordination currently includes, but is not limited to, value and risk-based arrangements, pharmacy services, vascular, cardiovascular and endovascular specialty services as well as ambulatory surgery center services, physician nephrology and cardiology services, urgent care services and ambulant treatment services. All of these Care Coordination services together with dialysis care and related services represent our health care services. We estimated the volume of the global dialysis market was approximately €80 billion in 2019. Due to the complexity and evolving nature of Care Coordination services, we are currently unable to estimate the global volume of this market. Dialysis patient growth results from factors such as the aging population and increased life expectancies; shortage of donor organs for kidney transplants; increasing incidence of kidney disease and better treatment of and survival of patients with diabetes, hypertension and other illnesses, which frequently lead to the onset of chronic kidney disease; improvements in treatment quality, new pharmaceuticals and product technologies, which prolong patient life; and improving standards of living in developing countries, which make life-saving dialysis treatment available. We are also engaged in different areas of health care research.

As a global company delivering health care services and products, we face the challenge of addressing the needs of a wide variety of stakeholders, such as patients, customers, payors, regulators and legislators in

many different economic environments and health care systems. In general, government-funded programs (in some countries in coordination with private insurers) pay for certain health care items and services provided to their citizens. Not all health care systems provide for dialysis treatment. Therefore, the reimbursement systems and ancillary services utilization environment in various countries significantly influence our business.

Premium assistance programs

On August 18, 2016, the Centers for Medicare and Medicaid Services ("CMS") issued a request for information ("RFI") seeking public comment about providers' alleged steering of patients inappropriately to individual plans offered on the Patient Protection and Affordable Care Act individual health insurance market. The holding company for our U.S. operations, Fresenius Medical Care Holdings, Inc. ("FMCH"), and other dialysis providers, commercial insurers and other industry participants responded to the RFI, and in that response, we reported that we do not engage in such steering. On December 14, 2016, CMS published an Interim Final Rule ("IFR") titled "Medicare Program; Conditions for Coverage for End-Stage Renal Disease Facilities-Third Party Payment" that would amend the Conditions for Coverage for dialysis providers, like FMCH. The IFR would have effectively enabled insurers to reject premium payments made by patients who received grants for individual market coverage from the American Kidney Fund ("AKF") and, therefore, could have resulted in those patients losing their individual market health insurance coverage. The loss of individual market coverage for these patients would have had a material and adverse impact on our operating results. See "Risk Factors—Changes in reimbursement and/or governmental regulations for health care could materially decrease our revenues and operating profit" in our 2019 Form 20-F. On January 25, 2017, a federal district court in Texas, responsible for litigation initiated by a patient advocacy group and dialysis providers including FMCH, preliminarily enjoined CMS from implementing the IFR (Dialysis Patient Citizens v. Burwell (E.D. Texas, Sherman Div.)). The preliminary injunction was based on CMS' failure to follow appropriate notice-and-comment procedures in adopting the IFR. The injunction remains in place and the court retains jurisdiction over the dispute. On June 22, 2017, CMS requested a stay of proceedings in the litigation pending further rulemaking concerning the IFR. CMS stated, in support of its request that it expects to publish a Notice of Proposed Rulemaking in the Federal Register and otherwise pursue a notice-and-comment process in the fall of 2017 which they ultimately did not publish. Plaintiffs in the litigation, including FMCH, consented to the stay, which was granted by the court.

Separately, the United States Department of Health and Human Services ("HHS") has drafted a new proposed rule entitled "Conditions for Coverage for End-Stage Renal Disease Facilities—Third Party Payments" (CMS-3337-P). While the proposed rule has been under review by the Office of Management and Budget since June 2019, and the HHS identified a target date of (11/00/19) for publication, the proposed rule has not yet been published for comment.

The operation of charitable assistance programs like that of the AKF is also receiving increased attention by state insurance regulators and legislators. The result may be a regulatory framework that differs from state to state. Even in the absence of the IFR or similar state actions, insurers are likely to continue efforts to thwart charitable premium assistance to our patients for individual market plans and other insurance coverages. If successful in a material area or scope of our U.S. operations, these efforts would have a material adverse impact on our business and operating results.

On January 3, 2017, FMCH received a subpoena from the United States Attorney for the District of Massachusetts inquiring into its interactions and relationships with AKF, including its charitable contributions to the Fund and the Fund's financial assistance to patients for insurance premiums. FMCH cooperated with the investigation, which was part of a broader investigation into charitable contributions in the medical industry. On August 1, 2019, the United States District Court for the District of Massachusetts entered an order announcing that the United States had declined to intervene on a qui tam complaint underlying the Boston United States Attorney's Office ("USAO") investigation and unsealing the relator's complaint so as to permit the relator to serve the complaint and proceed on his own. The relator did not serve the complaint within the time allowed but the court has not yet dismissed the relator's complaint.

U.S. ballot initiatives and other legislation

Further federal or state legislation or regulations may be enacted in the future through legislative and public referendum processes that could substantially modify or reduce the amounts paid for services and products offered by us and our subsidiaries and/or mandate new or alternative operating models and payment models that could present more risk to our health care service operations. Ballot initiatives that are successfully introduced at the state level in the United States require the vote of state citizens to directly adopt or reject proposed new legislation. These ballot initiatives require a material expenditure of resources by us to participate in public discourse regarding the proposed new legislation underlying the initiatives, which if passed, could further regulate multiple aspects of our operations including, for instance, clinic staffing requirements, state inspection requirements and profit margins on commercial business. Efforts to enact new state laws regarding our operations are continuing. State regulation at this level would introduce an unprecedented level of oversight and additional expense at the clinic level which could have a material adverse effect on our business in the impacted states. It is also possible that statutes may be adopted or regulations may be promulgated in the future that impose additional eligibility requirements for participation in the federal and state health care programs. Such new legislation or regulations could, depending upon the detail of the provisions, have positive or adverse effects, possibly material, on our businesses and results of operations.

Significant U.S. reimbursement developments

The majority of health care services we provide are paid for by governmental institutions. For the three months ended March 31, 2020, approximately 33% of our consolidated revenue is attributable to U.S. federally-funded health care benefit programs, such as Medicare and Medicaid reimbursement, under which reimbursement rates are set by CMS. Legislative changes could affect Medicare reimbursement rates for a significant portion of the services we provide. In recent years, the stability of reimbursement in the U.S. has been affected by (i) the implementation of the ESRD prospective payment system ("ESRD PPS") in January 2011, (ii) the U.S. federal government across the board spending cuts in payments to Medicare providers commonly referred to as "U.S. Sequestration" as well as the current moratorium on such cuts, (iii) the reduction to the ESRD PPS rate to account for the decline in utilization of certain drugs and biologicals associated with dialysis pursuant to the American Taxpayer Relief Act of 2012 ("ATRA") as subsequently modified under the Protecting Access to Medicare Act of 2014 ("PAMA") and (iv) CMS' 2017 final rule on the Physician Fee Schedule, which partially corrected reimbursement for certain procedures that were materially undervalued in 2016. Please see the detailed discussions on these and further legislative developments below:

•

Under the Medicare Improvements for Patients and Providers Act of 2008 ("MIPPA"), for patients with Medicare coverage, all ESRD payments for dialysis treatments are made under a single bundled payment rate which provides a fixed payment rate, the ESRD PPS, to encompass substantially all goods and services provided during the dialysis treatment. MIPPA further created the ESRD quality incentive program ("QIP") which provides that dialysis facilities in the United States that fail to achieve annual quality standards established by CMS could have base payments reduced in a subsequent year by up to 2%.

•

MIPPA also includes a provision for an annual adjustment to the ESRD PPS base rate based on changes in the costs of a "market basket" of certain healthcare items and services, less a productivity adjustment.

•

Additionally, as a result of the Budget Control Act of 2011 ("BCA") and subsequent activity in Congress, U.S. Sequestration ($1.2 trillion in across-the-board spending cuts in discretionary programs) took effect on March 1, 2013 and is expected to continue through mid-2024. In particular, a 2% reduction to Medicare payments took effect on April 1, 2013 and continues in force. The 2% sequestration has been temporarily suspended from May 1, 2020 through December 31, 2020. Spending cuts pursuant to U.S. Sequestration have adversely affected and will continue to adversely affect our operating results after the suspension is lifted.

•

In 2014, as mandated by ATRA, CMS issued a final rule for the ESRD PPS, which phased in payment reductions to account for changes in utilization of certain drugs and biologicals that are included in the ESRD PPS, which were subsequently modified by PAMA. These reductions reduced our market basket inflation adjustment by 1.25% in 2016 and 2017 and reduced our inflation adjustment by 1% in 2018.

•

On October 31, 2019, CMS issued a final rule for the ESRD PPS rate for calendar year (CY) 2020. On average, large dialysis organizations will receive a 1.7% increase in payments under this final rule. The base rate per treatment is $239.33 which represents a 1.7% increase from the 2019 base rate including the adjustment for the wage index budget-neutrality factor. The 2020 final rule reflects a market basket increase of 2.0% that is partially offset by a 0.3% multifactor productivity adjustment (as mandated by the ACA) and application of the wage index budget-neutrality adjustment factor of 1.000244. The 2020 ESRD PPS rate retains the 2019 wage index floor of 0.5000. The labor-related portion of the ESRD PPS base rate to which the wage index is applied will be 52.3% in 2020. CMS updated the Acute Kidney Injury payment rate for CY 2020 to $239.33, which is the same as the base rate finalized under the ESRD PPS for CY 2020. In the final rule, effective January 1, 2020, CMS also revised the transitional drug add-on payment adjustment ("TDAPA"). Under the CY 2019 final rule, all new renal dialysis drugs and biological products became eligible for TDAPA, not just those in new ESRD PPS functional categories. However, in the CY 2020 final rule, CMS narrowed that policy to exclude from eligibility certain non-innovative drugs approved by FDA (e.g., generics, reformulations of existing drugs, and other types of new drug applications (NDAs) that do not represent truly new therapies). In the CY 2019 final rule, CMS also changed the basis of payment for the TDAPA from pricing methodologies under section 1847A of the Act, which includes average sales price ("ASP") plus 6 percent ("ASP+6"), to 100 percent of ASP ("ASP+0"). However, that change did not apply to calcimimetics under the TDAPA. In the CY 2020 final rule, CMS extended pricing based on ASP+0 to calcimimetics under the TDAPA.

•

In the 2020 ESRD PPS final rule, CMS finalized several programmatic updates to the ESRD QIP and codified data submission requirements for calculating measure scores. Under the ESRD QIP program, CMS assesses the total performance of each facility on measures specified per payment year and applies an appropriate payment reduction to each facility that does not meet a minimum total performance score ("TPS"). For performance year 2022, CMS estimated that a facility must meet or exceed a minimum TPS of 54 in order to avoid a payment reduction. CMS updated the scoring methodology for the NHSN Dialysis Event reporting measure to allow new eligible facilities to report data on the measure. The 2020 ESRD PPS final rule automatically advances the performance period and baseline period for each payment year by one year from the previous year, beginning with the PY 2024 payment year. The 2020 ESRD PPS final rule also includes requirements for the Extraordinary Circumstances Exception (ECE) process, which grants facilities exceptions to certain reporting requirements in the QIP. In the final rule, CMS converts the Standardized Transfusion Ratio ("STrR") clinical measure used in the QIP to a reporting measure while it examines the validity of the STrR clinical measure. The final rule also finalizes payment reductions of up to two percent for the PY 2022 ESRD QIP. The total payment reductions for the approximate 1,871 out of 7,386 Medicare-enrolled dialysis facilities expected to receive a payment reduction is approximately $18.2 million for the 2020 performance year.

On July 29, 2019, CMS issued the CY 2020 final rule for hospital outpatient and ambulatory surgery center payment systems. For CY 2020, CMS will continue to pay for services covered by certain dialysis vascular access codes at the Ambulatory Surgical Center ("ASC") rate. The final rule updating the ASC Fee Schedule for CY 2020 generally increased the reimbursement rates for certain vascular access services. For the range of procedures provided in an ASC, the average increase is 3.4% compared to the prior year. CMS also updated the Physician Fee Schedule for CY 2020. For the range of procedures provided in a physician office, the CY 2020 Physician Fee Schedule represents, on average, no change in reimbursement compared to the prior year.

Presently, there is considerable uncertainty regarding possible future changes in health care regulation, including the regulation of reimbursement for dialysis services. See "Risk factors—We operate in a highly regulated industry such that the potential for legislative reform provides uncertainty and potential threats to our operating models and results" which is included in our Annual Report on Form 20-F for the year ended December 31, 2019.

Non-oral ESRD-related drugs are generally reimbursed as part of the ESRD PPS bundled payment. Oral only ESRD-related drugs are generally reimbursed outside the ESRD PPS bundled payment. In a final rule published on November 6, 2015, CMS provided for implementation of the PAMA oral-only provision. CMS clarified that once any non-oral ESRD-related drug in a category previously considered oral only is approved by the U.S. Food and Drug Administration ("FDA"), such category of drugs will cease to be considered oral only. However, for at least two years, CMS will pay for both oral and non-oral versions of the drug using a TDAPA. During this transition period, CMS will not pay outlier payments for these drugs,

but the agency will collect data reflecting utilization of both the oral and injectable or intravenous forms of the drugs, as well as payment patterns, in order to help determine how to appropriately adjust the ESRD PPS payment rate as these drugs are included in the payment bundle. At the end of this transition period, CMS will incorporate payment for the oral and non-oral versions of the drug in the ESRD PPS payment rates, utilizing a public rulemaking process.

The introduction of Parsabiv™ an intravenous calcimimetic, has resulted in changes in how some payors, other than Medicare, arrange for the provision of calcimimetics for their patients. While some patients continue to receive calcimimetics from their pharmacies as a pharmacy benefit, other patients receive calcimimetics from their dialysis providers, as a medical benefit. While we receive additional reimbursement from some payors when these drugs are provided by our clinics, this type of transition from an oral-only drug has not occurred previously and the reimbursement landscape for non-Medicare payors continues to evolve.

Several generic calcimimetic products have been approved by the FDA. FMCH has been able to purchase certain of these generic calcimimetic products at rates that are lower than the rate paid for the brand name calcimimetic, Sensipar. See Item 4B. "Information on the Company—Business Overview—Regulatory and Legal Matters—Reimbursement."

For additional information, see "Risk Factors—If we are unable to secure appropriate reimbursement arrangements for the pharmaceuticals we provide in our dialysis clinics, our business could be adversely affected" in our Annual Report on Form 20-F for the year ended December 31, 2019.

Participation in new Medicare payment arrangements

Under CMS' Comprehensive ESRD Care Model (the "Model"), dialysis providers and physicians have formed entities known as ESRD Seamless Care Organizations ("ESCOs") as part of a payment and care delivery pilot program that seeks to deliver better health outcomes for Medicare ESRD patients while lowering CMS' costs. Following our initial participation in six ESCOs, we are presently participating in the Model through 23 ESCOs formed at our dialysis facilities. ESCOs that achieve the program's minimum quality thresholds and generate reductions in CMS' cost of care above certain thresholds for the ESRD patients covered by the ESCO will receive a share of the cost savings, which is adjusted based on the ESCO's performance on certain quality metrics. ESCOs that include dialysis chains with more than 200 facilities are required to share in the risk of cost increases and to reimburse CMS a share of any such increases if actual costs rise above set thresholds. As of March 2020, the number of patients participating in our ESCOs was approximately 48,000.

In November 2017, we announced the results from the first performance year ("PY") from our ESCOs. The results, which cover the period from October 2015 through December 2016, show improved health outcomes for patients receiving coordinated care through the ESCOs. This success was validated by an independent report, which showed a nearly 9% decrease in hospitalization rates for these patients during the same time. In the second performance year (calendar year ("CY") 2017) the Company's ESCOs together generated more than $66.7 M in gross savings, an average 3.4% reduction in expenditures per patient. CMS has not yet published the final settlement reports for the third performance year (CY 2018). The ESCO pilot program will run until the end of 2020.

We have also entered into sub-capitation and other risk-based and value-based arrangements with certain payors to provide care to commercial and Medicare Advantage, ESRD and CKD patients. Under these arrangements, a baseline per patient per month amount is established. If we provide complete care for less than the baseline, we retain the difference. If the cost of complete care exceeds the baseline, we may owe the payor the difference.

Executive order-based models

On July 10, 2019, President Trump signed an Executive Order on advancing kidney health. Among other things, the order instructs the Secretary of HHS to develop new Medicare payment models that will encourage identification and treatment earlier in kidney disease progression as well as increased home dialysis and transplant. One of those models, the ESRD Treatment Choices ("ETC") model, is a mandatory model that will create financial incentives for home treatment and transplant. This model proposes to apply both positive and negative payment adjustments to claims submitted by physicians and dialysis facilities for home dialysis patients for 3 years. This model also proposes a payment adjustment based on performance. The performance-based adjustment will be based on home dialysis and transplant

rates and will range from (8%) to 5% in the first payment year to (13%) and 10% percent in the final payment year. The ETC model initially proposed a start date of January 2020 and would end in 2026, however CMS has postponed the start date of the ETC model. Participants in this model will be selected randomly. Pursuant to the Executive Order, the Secretary also announced voluntary payment models, Kidney Care First ("KCF") and Comprehensive Kidney Care Contracting ("CKCC") model (graduated, professional and global), which aims to build on the existing Comprehensive End Stage Renal Disease Care model. The voluntary models create financial incentives for health care providers to manage care for Medicare beneficiaries with chronic kidney disease stages 4 and 5 and with ESRD to delay the start of dialysis and to incentivize kidney transplant. The voluntary models allow health care providers to take on various amounts of risk. One model, the CKCC global model, allows renal health care providers to participate by forming an entity known as a Kidney Care Entity ("KCE"). Through the KCE, renal health care providers take responsibility for 100 percent of the total cost of care for all Medicare Part A and B services for aligned beneficiaries. The KCF model limits participation to nephrologists while the CKCC model requires participation by both nephrologists or nephrology practices and transplant providers. Dialysis providers and other suppliers may participate. Applications for the voluntary models were submitted in January 2020, but CMS has not provided a timeline for when the acceptance of decisions will be made. We submitted 25 CKCC applications and are also included in four other CKCC applications submitted by nephrologists. Once implemented, the CKCC model is expected to run through 2023. It is too soon to predict the effects on our business of the ETC payment model and the voluntary payment models.

Company structure

Our operating segments are the North America Segment, the EMEA Segment, the Asia-Pacific Segment and the Latin America Segment. The operating segments are determined based upon how we manage our businesses with geographical responsibilities. All segments are primarily engaged in providing health care services and the distribution of products and equipment for the treatment of ESRD and other extracorporeal therapies. Management evaluates each segment using measures that reflect all of the segment's controllable revenues and expenses. With respect to the performance of business operations, management believes that the most appropriate IFRS measures are revenue, operating income and operating income margin. We do not include income taxes as we believe this is outside the segments' control. Financing is a corporate function which our segments do not control. Therefore, we do not include interest expense relating to financing as a segment measurement. Similarly, we do not allocate certain costs which relate primarily to certain headquarters' overhead charges, including accounting and finance, because we believe that these costs are also not within the control of the individual segments. Production of products, production asset management, quality and supply chain management as well as procurement related to production are centrally managed. Products transferred to the segments are transferred at cost; therefore, no internal profit is generated. The associated internal revenue for the product transfers and their elimination are recorded as corporate activities. Capital expenditures for production are based on the expected demand of the segments and consolidated profitability considerations. The Company's global research and development as well as its Global Medical Office (as of January 1, 2020), which seeks to standardize medical treatments and clinical processes within the Company, are also centrally managed. These corporate activities do not fulfill the definition of a segment according to IFRS 8. In addition, certain revenues, investments and intangible assets, as well as any related expenses, are not allocated to a segment but accounted for as Corporate. Accordingly, all of these items are excluded from our analysis of segment results and are discussed below in the discussion of our consolidated results of operations. See note 10 of the notes to consolidated financial statements (unaudited) found elsewhere in this report) for a further discussion on our operating segments.

II.    Discussion of measures

Non-IFRS measures

Certain of the following key performance indicators and other financial information as well as discussions and analyses set out in this report include measures that are not defined by IFRS ("Non-IFRS Measure"). We believe this information, along with comparable IFRS measurements, is useful to our investors as it provides a basis for assessing our performance, payment obligations related to performance-based compensation as well as our compliance with financial covenants. Non-IFRS financial measures should not be viewed or interpreted as a substitute for financial information presented in accordance with IFRS.

Table of Contents

Some key performance indicators and other financial measures used in this report such as changes in revenue, operating income and net income attributable to shareholders of FMC-AG & Co. KGaA include the impact of translating local currencies to our reporting currency for financial reporting purposes. We calculate these Non-IFRS financial measures at constant exchange rates in our filings to show changes in our revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items without giving effect to period-to-period currency fluctuations. Under IFRS, amounts received in local (non-euro) currency are translated into euro at the average exchange rate for the period presented. Once we translate the local currency for the constant currency, we then calculate the change, as a percentage, of the current period calculated using the prior period exchange rates versus the prior period. This resulting percentage is a Non-IFRS Measure referring to a change as a percentage at constant currency. These currency-adjusted financial measures are identifiable by the designated terms "Constant Exchange Rates" or "Constant Currency."

We believe that the measures at Constant Currency are useful to investors, lenders and other creditors because such information enables them to gauge the impact of currency fluctuations on our revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items from period to period. In addition, under our long-term incentive plans, we measure the attainment of certain pre-determined financial targets for revenue growth and net income growth in Constant Currency. However, we limit our use of Constant Currency period-over-period changes to a measure for the impact of currency fluctuations on the translation of local currency into euro. We do not evaluate our results and performance without considering both:

(1)

period-over-period changes in revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items prepared in accordance with IFRS, and



(2)

Constant Currency changes in revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items.

We caution the readers of this report to follow a similar approach by considering data on Constant Currency period-over-period changes only in addition to, and not as a substitute for or superior to, changes in revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items prepared in accordance with IFRS. We present the growth rate derived from non-IFRS measures next to the growth rate derived from IFRS measures such as revenue, operating income, net income attributable to shareholders of FMC-AG & Co. KGaA and other items. As the reconciliation is inherent in the disclosure, we believe that a separate reconciliation would not provide any additional benefit.

Delivered operating income (Non-IFRS Measure)

As a result of the significance of noncontrolling interest holders in our operations, we believe a measure that is meaningful to investors is operating income less noncontrolling interests ("Delivered Operating Income"). Delivered Operating Income approximates the operating income attributable to the shareholders of FMC-AG & Co. KGaA. As such, we believe that operating income is the closest comparable IFRS measure. Delivered Operating Income is also benchmarked based on movement at Constant Exchange Rates.

Below is a table showing the reconciliation of operating income to Delivered Operating Income on a consolidated basis and for our reporting segments:

Net cash provided by (used in) operating activities in % of revenue

Our consolidated statement of cash flows indicates how we generated and used cash and cash equivalents. In conjunction with our other primary financial statements, it provides information that helps us evaluate changes to our net assets and our financial structure (including liquidity and solvency). Net cash provided by (used in) operating activities is applied to assess whether a business can generate the cash required to

make the necessary replacement and expansion of investments. This indicator is impacted by the profitability of our business and the development of working capital, mainly receivables. Net cash provided by (used in) operating activities in percent of revenue shows the percentage of our revenue that is available in terms of financial resources. It is an indicator of our operating financial strength.

Free cash flow in % of revenue (Non-IFRS Measure)

Free cash flow (net cash provided by (used in) operating activities after capital expenditures, before acquisitions and investments) refers to the cash flow we have at our disposal, including cash flows that may be restricted for other uses. This indicator shows the percentage of revenue available for acquisitions and investments, dividends to shareholders, reducing debt financing or for repurchasing shares.

The following table shows the cash flow key performance indicators for the three months ended March 31, 2020 and 2019 and reconciles free cash flow and free cash flow in percent of revenue to Net cash provided by (used in) operating activities and Net cash provided by (used in) operating activities in percent of revenue, respectively:

Net leverage ratio (Non-IFRS Measure)

The net leverage ratio is a key performance indicator used for internal management. To determine the net leverage ratio, debt and lease liabilities less cash and cash equivalents (net debt) is compared to adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) (adjusted for acquisitions and divestitures made during the last twelve months with a purchase price above a €50 M threshold as defined in the Amended 2012 Credit Agreement, non-cash charges and impairment loss). The ratio is an indicator of the length of time the Company needs to service the net debt out of its own resources. We believe that the net leverage ratio provides alternative information that management believes to be useful in assessing our ability to meet our payment obligations in addition to considering the absolute amount of our debt. We have a strong market position in a growing, global and mainly non-cyclical market. Furthermore, most of our customers have a high credit rating as the dialysis industry is characterized by stable and sustained cash flows. We believe this enables us to work with a reasonable proportion of debt, through the employment of an extensive mix of debt.

Adjusted EBITDA is also the basis for determining compliance with certain other covenants contained in our Amended 2012 Credit Agreement and is also relevant in certain of our other major financing arrangements. You should not consider adjusted EBITDA to be an alternative to net earnings determined in accordance with IFRS or to cash flow from operations, investing activities or financing activities. In addition, not all funds depicted by adjusted EBITDA are available for management's discretionary use. For example, a substantial portion of such funds are subject to contractual restrictions and functional requirements to fund debt service, capital expenditures and other commitments from time to time as described in more detail elsewhere in this report.

The following table shows the reconciliation of adjusted EBITDA and net leverage ratio as of March 31, 2020 and December 31, 2019.

Return on invested capital ("ROIC") (Non-IFRS Measure)

ROIC is the ratio of operating income, for the last twelve months, after tax ("net operating profit after tax" or "NOPAT") to the average invested capital of the last five quarter closing dates, including adjustments for acquisitions and divestitures made during the last twelve months with a purchase price above a €50 M threshold as defined in the Amended 2012 Credit Agreement, and expresses how efficiently we allocate the capital under our control or how well we employ our capital with regard to a specific investment project. An adjustment to exclude amounts related to the IFRS 16 Implementation is included for the purpose of increasing the comparability of previously reported information in accordance with our long-term incentive plans in 2019. The following table shows the reconciliation of average invested capital
