ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Management’s Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is intended to provide information to assist you in better understanding and evaluating our financial condition and results of operations. We encourage you to read this MD&A in conjunction with our consolidated financial statements and the notes thereto included in Part II, Item 8 of this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and uncertainties. Please refer to the information under the heading "Cautionary Note Regarding Forward-Looking Statements" elsewhere in this report. References to the words "we," "our," "us," and the "Company" in this report refer to NovoCure Limited, including its consolidated subsidiaries.

Overview

We are a global oncology company with a proprietary platform technology called Tumor Treating Fields ("TTFields"), which are electric fields tuned to specific frequencies that disrupt cancer cell division. Our key priorities are to drive commercial adoption of Optune and Optune Lua, our commercial TTFields delivery systems, and to advance clinical and product development programs intended to extend overall survival in some of the most aggressive forms of cancer.

Optune is approved by the U.S. Food and Drug Administration ("FDA") under the Premarket Approval ("PMA") pathway for the treatment of adult patients with newly diagnosed GBM in combination with temozolomide, a chemotherapy drug, and for adult patients with GBM following confirmed recurrence after chemotherapy as monotherapy treatment. We also have approval or a CE certificate to market Optune for the treatment of GBM in the European Union ("EU"), Japan and certain other countries. We market Optune in the U.S., Austria, Germany, Israel, Japan, Sweden and Switzerland, which we refer to as our "active markets." With respect to GBM, our sales and marketing efforts are principally focused on driving adoption with both neuro-oncologists and radiation oncologists. We are expanding our commercial operations into France with an initial focus on developing key opinion leader relationships in GBM and establishing a path to reimbursement for our Products.

Optune Lua is approved by the FDA under the Humanitarian Device Exemption ("HDE") pathway to treat MPM in combination with standard chemotherapies. We have received CE certification to market Optune Lua (under the name "NovoTTF-100L") in the EU and Switzerland. We currently market Optune Lua in the U.S., and are evaluating plans to expand access to our therapy for MPM patients in other markets. With respect to MPM, our commercial efforts are principally focused on generating awareness and on establishing a dialogue with third-party payers around access to Optune Lua.

We believe the mechanism of action behind TTFields therapy may be broadly applicable to solid tumor cancers. Currently, we are conducting phase 3 pivotal trials evaluating the use of TTFields in brain metastases from non-small-cell lung cancer ("brain metastases"), non-small-cell lung cancer ("NSCLC"), ovarian cancer and pancreatic cancer. In 2020, we enrolled our first patient in our global phase 4 TRIDENT trial to test the potential survival benefit of initiating Optune concurrent with radiation therapy versus following radiation therapy in patients with newly diagnosed GBM. We are also conducting phase 2 pilot trials evaluating the use of TTFields in liver cancer and gastric cancer, as well as testing the potential incremental survival benefit of TTFields delivered using high-intensity arrays versus standard arrays. We anticipate expanding our clinical pipeline over time to study the safety and efficacy of TTFields for additional solid tumor indications and combinations with other cancer treatment modalities. In the second quarter of 2021, we plan to launch the KEYNOTE B36 phase 2 pilot trial to study TTFields with pembrolizumab in first-line NSCLC through our clinical trial collaboration with MSD (a tradename of Merck & Co., Inc.).

50

The table below presents the current status of the ongoing clinical trials in our pipeline and anticipated timing of final data.

Our therapy is delivered through a medical device and we continue to advance our Products with the intention to extend survival and maintain quality of life for patients. We have several product development programs underway that prioritize impact on both TTFields' dose and patient ease of use. Our intellectual property portfolio contains over 185 issued patents and numerous patent applications pending worldwide. We believe we own global commercialization rights to our Products in oncology and are well-positioned to extend those rights into the future as we continue to find innovative ways to improve our Products.

In 2018, we granted Zai Lab (Shanghai) Co., Ltd. ("Zai") a license to commercialize Optune in China, Hong Kong, Macau and Taiwan ("Greater China") under a License and Collaboration Agreement (the "Zai Agreement"). The Zai Agreement also establishes a development partnership intended to accelerate the development of TTFields in multiple solid tumor cancer indications. For additional information, see Note 12 to the Consolidated Financial Statements.

Impact of COVID-19

In March 2020, the World Health Organization (“WHO”) declared COVID-19 a global pandemic. Since the pandemic began, we have been following the guidance of the WHO, the U.S. Centers for Disease Control and Prevention, and local health authorities in all of our active markets and we have adjusted the way we conduct business to adapt to the evolving situation. The COVID-19 pandemic did not have a material impact on our financial results throughout 2020. The pandemic has had and is having an impact on our day-to-day operations, which varies by region based on factors such as geographical spread, stage of containment and recurrence of the pandemic in each region. We believe the prolonged disruption caused by COVID-19 is resulting in increased volatility across global health care systems, such as fluctuations in patient volumes and changes in patterns of care in certain regions, which is currently impacting and might continue to impact our business and clinical trials in the future. For example, we continue to see fluctuations in the timing of surgeries and radiation therapy in certain regions, which has had some adverse influence on the eligible patient population for Optune. TTFields is an emerging modality in cancer care and requires significant educational effort to drive awareness and acceptance of our therapy. We have relied heavily on virtual engagement to manage these educational efforts for nearly a year, which poses challenges to our ability to effectively communicate and engage with our customers and partners around the world.

Given the aggressive nature of the cancers that we treat, we believe that the fundamental value proposition of the TTFields platform remains unchanged. We continue to evaluate and plan for the potential effects of COVID-19 on our business moving forward. The extent to which the COVID-19 pandemic may impact our business and clinical trials in the future will depend on further developments, which are highly uncertain and cannot be predicted with

51

confidence. The COVID-19 pandemic may also heighten many of the other risks described in our risk factors disclosed in this Annual Report.

We view our operations and manage our business in one operating segment. Our net revenues were $494.4 million for the year ended December 31, 2020, $351.3 million for the year ended December 31, 2019 and $248.1 million for the year ended December 31, 2018. Our net income was $19.8 million for the year ended December 31, 2020 and net loss $7.2 million for the year ended December 31, 2019 and $63.6 million for the year ended December 31, 2018. As of December 31, 2020, we had an accumulated deficit of $631.1 million. Our net income resulted primarily from net revenue growth coupled with an ongoing commitment to disciplined management of expenses.

Commentary on Results of Operations

Net revenues

Our revenues are primarily derived from patients using our Products in our active markets. We charge for treatment with our Products on a monthly basis. Our potential net revenues per patient are determined by our ability to secure payment, the monthly fee we collect and the number of months that the patient remains on therapy.

We also receive revenues pursuant to the Zai Agreement. For additional information regarding the Zai Agreement, see Note 12 to the Consolidated Financial Statements.

Cost of revenues

We contract with third parties to manufacture our Products. Our cost of revenues is primarily comprised of the following:

•disposable arrays;

•depreciation expense for the field equipment, including the electric field generator used by patients; and

•personnel and overhead costs such as facilities, freight and depreciation of property, plant and equipment associated with managing our inventory, warehousing and order fulfillment functions.

Operating expenses

Our operating expenses consist of research, development and clinical trials, sales and marketing and general and administrative expenses. Personnel costs are a significant component for each category of operating expenses and consist of wages, benefits and bonuses. Personnel costs also include share-based compensation.

Research, development and clinical trials

Our research, development and clinical trials activity is focused on advancing TTFields through clinical trials across multiple solid tumor types and improving the efficacy and usability of our delivery systems. Research, development and clinical trials costs, including direct and allocated expenses, are expensed as incurred and consist primarily of the following:

•personnel costs for those employees involved in our preclinical and basic research, clinical development programs, medical affairs, product development and regulatory activities;

•costs to conduct research, product development and clinical trial activity through agreements with contract research organizations and other third parties;

•manufacturing expenses associated with our Products, including durable components and disposable arrays, utilized in clinical trials and other research;

•costs associated with medical grants, publications, presentations and investigator-sponsored trials;

•professional fees related to regulatory approvals and conformity assessment procedures; and

•facilities, depreciation and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, depreciation of leasehold improvements and equipment and laboratory and other supplies.

52

The following table summarizes our research, development and clinical trial expenses by program for the years ended December 31, 2020, 2019 and 2018:

Year ended December 31,

Clinical development programs:

(1) Other research, development and clinical trial costs include regulatory affairs, quality assurance, intellectual property, product safety, allocated facilities, other overhead costs and share-based compensation.

We are committed to investing strategically to maximize the growth potential of the TTFields platform. We expect growth in our research and development investments to continue into 2021 as we work to advance our pipeline programs and increase acceptance of Tumor Treating Fields across the global oncology community.

Sales and marketing

Sales and marketing expenses consist primarily of personnel costs, travel, marketing and promotional activities, commercial shipping and facilities costs. Over the next few years, we expect to continue to make significant expenditures associated with selling and marketing our Products, primarily in connection with continued commercialization in the United States, EU and Japan for the treatment of our approved indications.

General and administrative

General and administrative expenses consist primarily of personnel, professional fees and facilities costs. General and administrative personnel costs include our executive, finance, human resources, information technology and legal functions. These costs also include our contributions to support industry and patient groups. Our professional fees consist primarily of accounting, information technology, legal and other consulting costs. We expect that general and administrative expenses will increase to support our growth. In addition, we incur significant legal and accounting costs related to compliance with SEC rules and regulations, including the costs of achieving and maintaining compliance with Section 404 of the Sarbanes-Oxley Act of 2002 and compliance with rules of the NASDAQ Stock Market, as well as insurance, investor relations and other costs associated with being a public company.

Financial expenses, net

Financial expenses, net primarily consists of credit facility interest expense and related debt issuance costs, interest income from cash balances and short-term investments and gains (losses) from foreign currency transactions. Our reporting currency is the U.S. dollar. We have historically held substantially all of our cash balances in U.S. dollar denominated accounts to minimize the risk of translational currency exposure.

Critical accounting policies and estimates

In accordance with U.S. GAAP, in preparing our financial statements we must make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of net revenues and expenses during the reporting period. We develop and periodically change these estimates and assumptions based on historical experience and on various

53

other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates.

The critical accounting policies requiring estimates, assumptions and judgments that we believe have the most significant impact on our consolidated financial statements are described below.

Revenue recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) (ASU 2014-09), an updated standard on revenue recognition and issued subsequent amendments to the initial guidance in March 2016, April 2016, May 2016 and December 2016 within ASU 2016-08, 2016-10, 2016-12 and 2016-20, respectively. The Company adopted the standard effective January 1, 2018 using the modified retrospective method for all contracts. The reported results for 2018 and thereafter reflect the application of Accounting Standards Codification ("ASC") 606 guidance while the reported results for 2017 were prepared under the guidance of ASC 605, Revenue Recognition (ASC 605). The amount of revenue recognized in 2018 and 2019 reflects the consideration to which the Company expects to be entitled to receive in exchange for our Products. The adoption of this standard did not have a material impact on our financial position, results of operations or cash flows. For additional information, see Note 2(m) to the Consolidated Financial Statements.

We also receive revenues pursuant to the Zai Agreement. For additional information regarding the Zai Agreement, see Note 12 to the Consolidated Financial Statements.

Share-based compensation

Under the FASB's ASC 718, Compensation-Stock Compensation, we measure and recognize compensation expense for share options granted to our employees and directors and for our ESPP based on the fair value of the awards on the date of grant. The fair value of share options is estimated at the date of grant using the Black-Scholes option pricing model and for market condition awards we also use the Monte-Carlo simulation model. Both models requires management to apply judgment and make estimates, including:

•the expected term of the stock option award, which we calculate using the simplified method, in accordance with ASC No.718-10-S99-1 (SAB No. 110) as we have insufficient historical information regarding our stock options to provide a basis for an estimate;

•the expected share price volatility of our underlying ordinary shares, which we estimate based on the historical volatility of a representative group of publicly traded biopharmaceutical and medical technology companies with similar characteristics to us for a period matching the expected term assumption when there is not sufficient historical information for our ordinary shares;

•the risk-free interest rate, which we base on the yield curve of U.S. Treasury securities with periods commensurate with the expected term of the options being valued; and

•the expected dividend yield, which we estimate to be zero based on the fact that we have never paid cash dividends and have no present intention to pay cash dividends.

For information about our ESPP, see Note 14(b) to the Consolidated Financial Statements.

We recognize share-based compensation costs only for those shares expected to vest over the requisite vesting period of the award, which is generally the option vesting term of four years, using the accelerated method.

The table below summarizes the assumptions that were used to estimate the fair value of the options granted to employees during the periods presented:

Year ended December 31,

54

If any of the assumptions used in the Black-Scholes option pricing model change significantly, share-based compensation for future awards may differ materially from the awards granted previously.

So long as our ordinary shares are publicly traded in a liquid market, we will rely on the daily trading price of our ordinary shares when we estimate the fair value of options granted.

We incurred share-based compensation expense of $75.7 million, $52.4 million and $39.8 million during the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, we have unrecognized compensation expense of $96.3 million, which is expected to be recognized over a weighted average period of approximately 2.9 years. We expect to continue to grant equity awards in the future, and to the extent that we do, our recognized share-based compensation expense will likely increase. For additional information, see Note 14(b) to the Consolidated Financial Statements.

Long-lived assets

Property and equipment and field equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful life of the relevant asset. We make estimates of the useful life of our property and equipment and field equipment, based on similar assets purchased in the past and our historical experience with such similar assets, in order to determine the depreciation expense to be recorded for each reporting period.

Our field equipment consists of equipment being utilized under rental agreements accounted for on a monthly basis as an operating lease, as well as service pool equipment. Service pool equipment is equipment owned and maintained by us that is swapped for equipment that needs repair or maintenance by us while being used by a patient. We record a provision for any excess, lost or damaged equipment when warranted based on an assessment of the equipment.

We assess impairment whenever events or changes in circumstances indicate that the carrying amount of the asset is impaired or the estimated useful life is no longer appropriate. Circumstances such as changes in technology or in the way an asset is being used may trigger an impairment review. For additional information, see Notes 2(i) and 2(j) to the Consolidated Financial Statements.

Inventories

Inventories are stated at the lower of cost or net realizable value. We regularly evaluate the ability to realize the value of inventory. If the inventories are deemed damaged, if actual demand for our delivery systems declines, or if market conditions are less favorable than those projected, inventory write-offs may be required. For additional information, see Note 2(h) to the Consolidated Financial Statements.

Income taxes

As part of the process of preparing our consolidated financial statements, we are required to calculate our income taxes based on taxable income by jurisdiction. We make certain estimates and judgments in determining our income taxes, including assessment of our uncertain tax positions, for financial statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in the subsequent period when such a change in estimate occurs.

Uncertain tax positions are based on estimates and assumptions that have been deemed reasonable by management. Our estimates of unrecognized tax benefits and potential tax benefits may not be representative of actual outcomes.

For additional information, see Note 13 to the Consolidated Financial Statements.

Key performance indicators

We believe certain commercial operating statistics are useful to investors in evaluating our commercial business as they help investors evaluate and compare the adoption of our Products from period to period. The number of active patients on therapy is our principal revenue driver. An "active patient" is a patient who is receiving treatment under a commercial prescription order as of the measurement date, including patients who may be on a temporary break from treatment and who plan to resume treatment in less than 60 days. Prescriptions are a leading indicator of demand. A "prescription received" is a commercial order for Optune or Optune Lua that is received from a physician certified to treat patients with our Products for a patient not previously on Optune or Optune Lua. Orders to renew or extend treatment are not included in this total.

Year ended December 31, 2020 compared to year ended December 31, 2019

The following discussion provides an analysis of our results of operations and reasons for material changes therein for 2020 as compared to 2019. See "Results of Operations" in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations in the Company's 2019 Annual Report on Form 10-K, filed with the SEC on February 27, 2019 (the "2019 Annual Report"), for analysis of the 2019 results as compared to 2018.

Year ended December 31,

Net revenues. Net revenues increased by $143.0 million, or 41%, to $494.4 million for the year ended December 31, 2020 from $351.3 million for the year ended December 31, 2019. This was primarily due to an increase of 502 active patients in our active markets, representing 17% growth, and an increase in the net revenues per active patient per month. The increase in net revenues per active patient per month was primarily driven by improving reimbursement approval rates in the U.S.

For the year ended December 31, 2020, we recorded $36 million in revenues from Medicare fee-for-service beneficiaries billed under the coverage policy compared to $6 million for the year ended December 31, 2019. We have gained a good understanding of how to ensure timely processing of Medicare claims and have sufficient experience to recognize approximately two-thirds of the expected contribution from Medicare beneficiaries.

We also recognized approximately $19 million in incremental net revenues in the second half of 2020 compared to the first half of 2020 resulting from the successful appeal of previously denied claims for Medicare fee-for-service beneficiaries billed prior to established coverage.

57

Year ended December 31,

Cost of revenues. Our cost of revenues increased by $17.9 million, or 20%, to $106.5 million for the year ended December 31, 2020 from $88.6 million for the year ended December 31, 2019. The increase in cost of revenues was primarily due to the cost of shipping arrays to a higher volume of commercial patients. Excluding sales to Zai, cost of revenues per active patient per month decreased 3% to $2,602 for the year ended December 31, 2020 from $2,694 for the year ended December 31, 2019 due to on-going efficiency initiatives and scale.

Cost of revenues per active patient is calculated by dividing the cost of revenues for the year less product sales to Zai for the year by the average of the active patients at the end of the each quarter in the current year and the end of the year active patients from the prior year. This annual figure is then divided by twelve to estimate the monthly cost of revenues per active patient. Sales to Zai are deducted because they are made at cost and in anticipation of future royalties from Zai, and Zai patient counts are not included in our active patient population. Product sales to Zai totaled $6.3 million for the year ended December 31, 2020 compared to $2.0 million for the year ended December 31, 2019.

Gross margin was 78% for the year ended December 31, 2020 and 75% for the year ended December 31, 2019. Gross margin continues to benefit from ongoing efficiency initiatives and increasing scale. Gross margin is also improved with revenue resulting from the successful appeal of previously denied claims for Medicare fee-for-service beneficiaries and tempered by product sales to Zai.

Year ended December 31,

Operating expenses:

Research, development and clinical trials expenses. Research, development and clinical trials expenses increased by $53.0 million, or 67%, to $132.0 million for the year ended December 31, 2020 from $79.0 million for the year ended December 31, 2019. The change is primarily due to increased investments in clinical trials and clinical administration personnel to advance and broaden our clinical development programs, preclinical and basic research to better understand the optimal use of TTFields, product development intended to optimize the delivery of TTFields therapy, and expanded medical affairs efforts to educate the clinical community.

We expect growth in our research and development investments to continue into 2021 as we work to advance our pipeline programs and increase acceptance of Tumor Treating Fields across the global oncology community. We balance our investments in research and development with our organizational capacity to effectively execute our strategic initiatives.

Sales and marketing expenses. Sales and marketing expenses increased by $21.3 million, or 22%, to $118.0 million for the year ended December 31, 2020 from $96.7 million for the year ended December 31, 2019. The change was primarily due to an increase in personnel and professional services costs to support our growing commercial business and reimbursement efforts and an increase in marketing expenses related to the launch of Optune Lua for MPM.

General and administrative expenses. General and administrative expenses increased by $19.5 million, or 22%, to $107.4 million for the year ended December 31, 2020 from $87.9 million for the year ended December 31, 2019. The change was primarily due to an increase in personnel costs, insurance premiums and professional services.

Year ended December 31,

Financial expenses, net. Financial expenses, net increased by $4.4 million, or 55%, to $12.3 million for the year ended December 31, 2020 from $7.9 million for the year ended December 31, 2019. The change was primarily due to a prepayment premium related to the 2018 Credit Facility, amortization costs related to the issuance of our

58

convertible notes and expenses related to the senior secured revolving credit facility. See Note 10 to the Consolidated Financial Statements.

Year ended December 31,

Income taxes. Income tax benefits increased by $0.1 million, or 7%, resulting in a tax benefit of $1.7 million for the year ended December 31, 2020 compared to a $1.6 million for the year ended December 31, 2019. The change was primarily a result of the impact of the U.S. CARES Act partially offset by business growth.

Non-GAAP financial measures

We also measure our performance based upon a non-U.S. GAAP measurement of earnings before interest, taxes, depreciation, amortization and shared-based compensation ("Adjusted EBITDA"). We believe Adjusted EBITDA is useful to investors in evaluating our operating performance because it helps investors evaluate and compare the results of our operations from period to period by removing the impact of earnings attributable to our capital structure, tax rate and material non-cash items, specifically share-based compensation.

We calculate Adjusted EBITDA as operating income before financial expenses and income taxes, net of depreciation, amortization and share-based compensation. The following table reconciles net loss (which is the most directly comparable U.S. GAAP operating performance measure) to Adjusted EBITDA.

Year ended December 31,

Adjusted EBITDA increased by $55.3 million, or 92%, to $115.3 million for the year ended December 31, 2020 from $60.0 million for the year ended December 31, 2019. This improvement in fundamental financial performance was driven by net revenue growth coupled with an ongoing commitment to disciplined management of expenses.

Liquidity and capital resources

We have incurred significant losses and cumulative negative cash flows from operations since our founding in 2000. As of December 31, 2020, we had an accumulated deficit of $631.1 million. To date, we have primarily financed our operations through the issuance and sale of equity and the proceeds from long-term loans.

At December 31, 2020, we had $234.7 million in cash and cash equivalents and $607.9 million in short-term investments. At December 31, 2020, our cash, cash equivalents and short-term investments totaled $842.6 million, an increase of $516.5 million compared to $326.1 million at December 31, 2019. The increase in our cash, cash equivalents and short-term investments was primarily due to convertible notes issued, net cash provided by operating activities and the exercise of options.

We believe our cash, cash equivalents and short-term investments as of December 31, 2020 are sufficient for our operations for at least the next 12 months based on our existing business plan and our ability to control the timing of significant expense commitments. We expect that our research, development and clinical trials expenses, sales and marketing expenses and general and administrative expenses will continue to increase over the next several years and may outpace our gross profit. As a result, we may need to raise additional capital to fund our operations.

59

The following summary of our cash flows for the periods indicated has been derived from our consolidated financial statements, which are included elsewhere in this Annual Report:

Year ended December 31,

Net cash provided by (used in) operating activities $ 99,148 $ 26,620 $ (1,865)

Net cash provided by (used in) investing activities (472,847) (51,667) (5,493)

Effect of exchange rate changes on cash and cash equivalents 247 26 27

Operating activities

Net cash provided by operating activities primarily represents our net income for the periods presented. Adjustments to net income for non-cash items include share-based compensation, depreciation, amortization and asset write-downs. Operating cash flows are also impacted by changes in operating assets and liabilities, principally trade payables, deferred revenues, other payables, prepaid expenses, inventory and trade receivables.

Net cash provided by operating activities was $99.1 million for the year ended December 31, 2020 compared to $26.6 million for the year ended December 31, 2019. Gross profit increased by $125.2 million in 2020 versus 2019, fully funding incremental investments of $53.0 million in research and development and $40.8 million in sales, marketing, general and administrative expenses. The year over year increase in cash provided by operating activities was driven primarily by higher cash earnings, lower interest payments, the receipt of income tax refunds and Zai Lab milestone payments, as well as the timing of receipts and payments in the ordinary course of business.

Upcoming uses of cash in operations will include payments in the normal course of business of $37.5 million in purchase obligations with certain of our suppliers, primarily for the purchase of Product components along with other commitments to purchase goods or services. These amounts include approximately $29.6 million of commitments with three major suppliers. We make such commitments through a combination of purchase orders, supplier contracts, and open orders based on projected demand information. We also have employment agreements with certain employees that require the funding of a specific level of payments if certain events, such as a change in control or termination without cause, occur. In the course of normal business operations, we also have agreements with contract service providers to assist in the performance of our research and development (including clinical trials) and manufacturing activities. We could also enter into additional collaborative research, contract research, manufacturing and supplier agreements in the future, which may require up-front payments and even long-term commitments of cash.

Investing activities

Our investing activities consist primarily of capital expenditures to purchase property and equipment and field equipment, as well as investments in and redemptions of our short-term investments.

Net cash used in investing activities was $472.8 million for the year ended December 31, 2020 compared to net cash used in investing activities of $51.7 million for the year ended December 31, 2019. The net cash used in investing activities for 2020 was primarily attributable to $15.0 million in property and equipment and the purchase of $607.9 million in short-term investments, mostly upon receipt of proceeds from the convertible note issuance, partially offset by $150.0 million in proceeds of short term investments to repay the 2018 Credit Facility. The net cash used in investing activities for 2019 was primarily attributable to $10.5 million in property and equipment and the net purchase of $41.2 million in short-term investments.

Financing activities

To date, our primary financing activities have been the sale of equity and the proceeds from long-term loans.

Net cash provided by financing activities was $440.2 million for the year ended December 31, 2020 compared to $61.7 million for the year ended December 31, 2019. The net cash provided by financing activities for 2020 was primarily attributable to $558.4 million in proceeds from the convertible note issuance and $31.8 million in proceeds from exercise of options and shares related to the ESPP partially offset by $150.0 million in repayment of the 2018 Credit Facility (see below). The net cash provided by financing activities for 2019 was primarily attributable to $61.7 million in proceeds from exercise of options and shares related to the ESPP.

60

Convertible Notes

On November 5, 2020, we issued issued $575.0 million aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”). The net proceeds from the offering were approximately $558.4 million. We intend to use the net proceeds to further advance our clinical and product development programs and to invest in associated pre-commercial and commercial activities, as well as for general corporate purposes.

The Notes are senior unsecured obligations. The Notes do not bear regular interest, and the principal amount of the Notes will not accrete. Special interest, if any, payable in accordance with the terms of the Notes will be payable in cash semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. The Notes mature on November 1, 2025, unless earlier repurchased, redeemed or converted.

The Notes are convertible at an initial conversion rate of 5.9439 ordinary shares per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $168.24 per ordinary share. In January 2021, we irrevocably elected to settle all conversions of Notes by a combination of cash and our ordinary shares and that the cash portion per $1,000 principal amount of Notes for all conversion settlements shall be $1,000, Accordingly, from and after the date of the election, upon conversion of any Notes, holders of Notes will receive, with respect to each $1,000 principal amount of Notes converted, cash in an amount up to $1,000 and the balance of the conversion value, if any, in our ordinary shares

The Notes are not redeemable prior to November 6, 2023, except in the event of certain tax law changes. We may redeem for cash all or any portion of the Notes, at our option, on or after November 6, 2023 if the last reported sale price of our ordinary shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes.

Prior to the close of business on the business day immediately preceding August 1, 2025, the Notes are convertible at the option of the holders only upon the satisfaction of certain conditions and during certain periods and if we exercise our right to redeem the Notes as permitted or required by the indenture. On or after August 1, 2025 until the close of the business on the business day immediately preceding the maturity date, holders may convert all or any portion of their Notes at the conversion rate at any time irrespective of the foregoing conditions.

Term loan credit facility

On November 6, 2020, we entered into a new three-year $150.0 million senior secured revolving credit facility with a syndicate of relationship banks (the "2020 Credit Facility"). We may, subject to certain conditions and limitations, increase the revolving credit commitments outstanding under the 2020 Credit Facility or incur new incremental term loans in an aggregate principal amount not to exceed an additional $100 million.

The commitments under the 2020 Credit Facility are guaranteed by certain of our subsidiaries and secured by a first lien on our and certain of our subsidiaries’ assets. Outstanding loans will bear interest at a sliding scale based on the our secured leverage ratio from LIBOR plus 2.75% to LIBOR plus 3.25% per annum. Additionally, the 2020 Credit Facility contains a fee for the unused revolving credit commitments at a sliding scale based on our secured leverage ratio from 0.35% to 0.45%. The 2020 Credit Facility contains financial covenants requiring maintenance of a minimum fixed charge coverage ratio and specifying a maximum senior secured net leverage ratio, as well as customary events of default which include a change of control. As of December 31, 2020, we were in compliance with such covenants.

As of December 31, 2020, we had no outstanding balance borrowed under the 2020 Credit Facility.

For additional information, see Note 12(c) to the Consolidated Financial Statements.

Prepayment of 2018 term loan

In 2018, we entered into a Loan and Security Agreement ("2018 Loan Agreement") pursuant to which we borrowed a term loan in the aggregate principal amount of $150.0 million (the "2018 Credit Facility"). The term loan, which was drawn in full upon execution of the 2018 Loan Agreement, bore interest at 9.0% per annum, payable quarterly in arrears. In 2020, we terminated the 2018 Credit Facility and prepaid the principal amount in full. The prepayment included $150.0 million in principal repayment and $3.0 million in prepayment premium, plus accrued and unpaid interest and expenses payable through the payoff date.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in interest rates and foreign currency exchange rates. We do not hold or issue financial instruments for trading purposes. There were no material quantitative changes in our market risk exposures between the year ended December 31, 2020 and the year ended December 31, 2019.

Interest rate sensitivity

Our exposure to market risk for changes in interest rates relates primarily to our investment portfolio. Our cash, cash equivalents and short-term investment accounts as of December 31, 2020 totaled $842.6 million and consist of cash, cash equivalents and short-term investments with maturities of less than one year from the date of purchase. Our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of the interest rates in the United States. However, because of the short-term nature of the instruments in our portfolio and our intent to hold instruments to maturity, a 10% change in market interest rates would not be expected to have a material impact on our financial condition or our results of operations.

Foreign currency exchange risk

Our consolidated results of operations and cash flow are subject to fluctuations due to changes in foreign currency exchange rates. All of our revenues are generated in the local currency for commercial markets. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States, Switzerland, Germany, Israel and Japan. Our consolidated results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign currency exchange rates and may be adversely affected in the future due to changes in foreign exchange rates. The effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have a material impact on our historical consolidated financial statements. We do not hedge our foreign currency exchange risk.

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

Note 1: Organization

NovoCure Limited (including its consolidated subsidiaries, the "Company") was incorporated in the Bailiwick of Jersey and is principally engaged in the development, manufacture and commercialization of Tumor Treating Fields ("TTFields") delivery systems, including Optune and Optune Lua (our "Products"), for the treatment of solid tumor cancers. The Company currently markets Optune in the U.S., Austria, Germany, Israel, Japan, Sweden and Switzerland. The Company currently markets Optune Lua in the U.S. The Company also has a License and Collaboration Agreement (the "Zai Agreement") with Zai Lab (Shanghai) Co., Ltd. ("Zai") to market Optune in Greater China. See Note 12.

During the year ended December 31, 2019, the Company implemented changes to its corporate entity operating structure, including transferring certain intellectual property to its Swiss subsidiary, primarily to align corporate entities with the Company’s evolving operations and business model.

Note 2: Basis of presentation and significant accounting policies

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”).

a. Use of estimates:

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The Company evaluates on an ongoing basis its assumptions, including those related to contingencies, deferred taxes, tax liabilities, useful-life of field equipment, right-of-use assets and lease liabilities, convertible notes, pension liabilities, revenue recognition, and share-based compensation costs. The Company’s management believes that the estimates, judgment and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of net revenue and expenses during the reporting period. Actual results could differ from those estimates.

b. Financial statements in U.S. dollars:

The accompanying financial statements have been prepared in U.S. dollars in thousands, except for share and per-share data.

The Company finances its operations in U.S. dollars and a substantial portion of its costs and revenues from its primary markets is incurred in U.S. dollars. As such, the Company’s management believes that the U.S. dollar is the currency of the primary economic environment in which NovoCure Limited and certain subsidiaries operate. The Company’s reporting currency is U.S. dollars.

Transactions and balances denominated in U.S. dollars are presented at their original amounts. Monetary accounts maintained in currencies other than the U.S. dollar are re-measured into dollars in accordance with Accounting Standards Codification (ASC) No. 830-10, "Foreign Currency Matters." All transaction gains and losses of the re-measurement of monetary balance sheet items are reflected in the consolidated statements of operations as financial income or expenses, as applicable.

For a subsidiary whose functional currency has been determined to be its local currency, assets and liabilities are translated at year-end exchange rates and statement of operations items are translated at average exchange rates prevailing during the year. Such translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in shareholders' equity.

c. Principles of consolidation:

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Intercompany transactions and balances, including unrealized profits from intercompany sales, have been eliminated upon consolidation.

76

Table of Contents

NovoCure Limited and subsidiaries

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

d. Cash equivalents:

Cash equivalents are short-term, highly liquid investments that are readily convertible into cash with a maturity of three months or less at the date acquired.

e. Short-term investments:

The Company accounts for investments in debt securities in accordance with ASC 320, "Investments—Debt and Equity Securities." Management determines the appropriate classification of its investments in marketable debt securities at the time of purchase and reevaluates such determinations at each balance sheet date. For the years ended December 31, 2020 and 2019, all securities are classified as held-to-maturity since the Company has the intent and ability to hold the securities to maturity and, accordingly, debt securities are stated at amortized cost.

The amortized cost of held-to-maturity securities is adjusted for amortization of premiums and accretion of discounts to maturity and any other than temporary impairment losses. Such amortization and interest are included in the consolidated statement of operations as financial income or expenses, as appropriate.

For the three years ended December 31, 2020, no impairment losses have been identified.

f. Restricted cash

The Company has restricted cash used as security for the use of Company credit cards and cash management, presented in short-term assets. Additionally, the Company has pledged bank deposits to cover bank guarantees related to facility rental agreements, fleet lease agreements and customs payments presented in other long-term assets (see Note 12).

g. Trade receivables:

The Company’s trade receivables balance contains billed and unbilled commercial activities. As needed, the Company records an allowance for doubtful accounts by reserving for specifically identified doubtful accounts. The Company periodically reviews its customers’ credit risk and payment history. To date, the Company has not experienced any material credit losses related to counter-party risk.

h. Inventories:

Inventories are stated at the lower of cost or net realizable value. Cost is determined using the weighted average method. The Company regularly evaluates its ability to realize the value of inventory. If the inventories are deemed damaged, if actual demand for the Company’s delivery systems deteriorates, or if market conditions are less favorable than those projected, inventory write-offs may be required.

Inventory write-offs of $616, $310 and $684, respectively, were recorded for the years ended December 31, 2020, 2019 and 2018.

i. Property and equipment:

Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets at the following rates:

%

Computers and laboratory equipment 15 - 33

Office furniture 6 - 33

Production equipment 20

j. Field equipment:

Field equipment is stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful life of the field equipment, which was determined to be 18 to 36 months. Field equipment is equipment being utilized under service agreements, and accounted for in accordance with ASC 842 on

77

Table of Contents

U.S. dollars in thousands (except share and per share data)

a monthly basis as an operating lease (see Note 2(x)). The Company records a write-off provision for any excess, lost or damaged equipment when warranted based on an assessment of the equipment. Write-offs for equipment are included in cost of revenues. During the years ended December 31, 2020, 2019 and 2018, write-offs for $409, $327 and $350, respectively, were recorded (see Note 7).

k. Impairment of long-lived assets:

The Company’s long-lived assets are reviewed for impairment in accordance with ASC 360-10, "Property, Plant and Equipment," whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability of an asset to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted cash flows expected to be generated by the asset. If such asset is considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds its fair value. During the three years ended December 31, 2020, no impairment losses have been identified.

l. Other long-term assets:

Restricted deposits and long-term lease deposits associated with office rent and vehicles under operating leases are presented in other long-term assets.

m. Revenue recognition:

Our Products are comprised of two main components: (1) an electric field generator and (2) arrays and related accessories. We retain title to the electric field generator, and the patient is provided replacement arrays and technical support for the device during the term of treatment. The electric field generator and arrays are always supplied and function together and are not sold on a standalone basis.

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-9, Revenue from Contracts with Customers (Topic 606) (ASU 2014-9), an updated standard on revenue recognition and issued subsequent amendments to the initial guidance in March 2016, April 2016, May 2016 and December 2016 within ASU 2016-8, 2016-10, 2016-12 and 2016-20, respectively (collectively, "ASC 606"). The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods and services to patients in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods and services. In addition, the new standard requires expanded disclosures. The Company has adopted the standard effective January 1, 2018 using the modified retrospective method for all contracts.

The Company uses the portfolio approach to apply the standard to portfolios of contracts with similar characteristics.

To recognize revenue under ASC 606, the Company applies the following five steps:

1.Identify the contract with a patient. A contract with a patient exists when (i) the Company enters into an enforceable contract with a patient that defines each party’s rights regarding delivery of and payment for a Product, (ii) the contract has commercial substance and (iii) the Company determines that collection of substantially all consideration for such Product is probable based on the payer’s intent and ability to pay the promised consideration. The evidence of a contract generally consists of a prescription, a patient service agreement and the verification of the assigned payer for the contract and intention to collect.

2.Identify the performance obligations in the contract. Our contracts include the lease of the device, the supply obligation of disposable arrays and technical support for the term of treatment. To the extent a contract includes multiple promised products and/or services, the Company must apply judgment to determine whether those products and/or services are capable of being distinct in the context of the contract. If these criteria are not met the promised products and/or services are accounted for as a combined performance obligation. In the Company’s case, the device, support, and disposables are provided as one inseparable package of monthly treatment for a single monthly fee. For more information, see Note 2(x).

3.Determine the transaction price. The transaction price is determined based on the consideration to which the Company will be entitled in exchange for providing a Product to the patient. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing either the expected value method or

78

Table of Contents

NovoCure Limited and subsidiaries

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

the most likely amount method depending on the nature of the variable consideration. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. The Company has agreements with many payers that define explicit discounts off the gross transaction price. In addition to the explicit discounts negotiated with each payer, the Company expects to receive, in aggregate for a given portfolio, less than the gross revenue net of explicit discounts. ASC 606 requires that the Company recognize this variable consideration as an implicit discount in the billing period. The implicit discount includes both an estimate of claims that will pay at an amount less than billed and an estimate of claims that will not pay within a given time horizon. The implicit discount adjustments to the transaction price are due to concessions, not collectability concerns driven by payer credit risk.

4.Allocate the transaction price to performance obligations in the contract. If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. As discussed above, there is a combined performance obligation under the Company’s contracts and, therefore, the monthly transaction price determined for the performance obligation will be recognized over time ratably over the monthly term of the treatment.

5.Recognize revenue when or as the Company satisfies a performance obligation. The Company satisfies performance obligations over time. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised service to a patient. The patient consumes the benefits of treatment on a daily basis over the monthly term. As this criterion is met, the revenues will be recognized over the monthly term. For more information, see Note 2(x).

Revenues are presented net of indirect taxes.

Net revenues in the years ended December 31, 2020, 2019 and 2018 also include amounts recognized pursuant to the Zai Agreement. For additional information, see Note 12.

n. Charitable care:

The Company provides treatment at no charge to patients who meet certain criteria under its charitable care policy. Because the Company does not pursue collection of amounts determined to qualify as charity, they are not reported as revenue. The Company's costs of care provided under charitable care were $3,653, $2,847 and $2,762 for the years ended December 31, 2020, 2019 and 2018, respectively. These amounts were determined by applying charitable care as a percentage of gross billings to total cost of goods sold.

o. Shipping and handling costs:

The Company does not separately bill its customers for shipping and handling costs associated with shipping Products to its customers. These direct shipping and handling costs of $3,224, $2,688 and $2,936 for the years ended December 31, 2020, 2019 and 2018, respectively, are included in Sales and Marketing costs.

p. Accounting for share-based compensation:

The Company accounts for share-based compensation in accordance with ASC 718, "Compensation—Stock Compensation." ASC 718 requires companies to estimate the fair value of share-based compensation awards on the date of grant using an option-pricing model. The value of the award is recognized as an expense over the requisite service periods in the Company’s consolidated statements of operations. The Company's policy is to account for forfeitures as they occur.

The Company recognizes compensation costs for the value of awards granted using the accelerated method over the requisite service period of the award, which is generally the restricted share unit vesting term of three years and option vesting term of four years, respectively.

The Company applies the Black-Scholes model as it believes it is the most appropriate fair value method for all equity awards and for the Employee Share Purchase Plan (the "ESPP"). For market condition awards, the Company also applies the Monte-Carlo simulation model. The Black-Scholes model requires a number of assumptions, of which the most significant are the share price, expected volatility and the expected award term.

The computation of expected volatility is based on actual historical share price volatility of comparable companies when there is not sufficient historical information for the Company. Expected term of options granted is calculated

79

Table of Contents

NovoCure Limited and subsidiaries

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

using the average between the vesting period and the contractual term to the expected term of the options in effect at the time of grant. The Company has historically not paid dividends and has no foreseeable plans to pay dividends and, therefore, uses an expected dividend yield of zero in the option pricing model. The risk-free interest rate is based on the yield of U.S. treasury bonds with equivalent terms.

q. Fair value of financial instruments:

The carrying amounts of cash and cash equivalents, short-term investments, restricted cash, receivables and prepaid expenses, trade receivables, trade payables and other accounts payable and accrued expenses approximate their fair value due to the short-term maturity of such instruments.

The Company accounts for certain assets and liabilities at fair value under ASC 820, "Fair Value Measurements and Disclosures." Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.

The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. The Company categorizes each of its fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety.

The three levels of inputs that may be used to measure fair value are as follows:

Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets;

Level 2 - Includes other inputs that are directly or indirectly observable in the marketplace, other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets with insufficient volume or infrequent transactions, or other inputs that are observable (model-derived valuations in which significant inputs are observable), or can be derived principally from or corroborated by observable market data; and

Level 3 - Unobservable inputs which are supported by little or no market activity.

The availability of observable inputs can vary from instrument to instrument and is affected by a wide variety of factors, including, for example, the type of instrument, the liquidity of markets and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment and the instrument is categorized as Level 3.

r. Basic and diluted net loss per share:

Basic net income (loss) per share is computed based on the weighted average number of ordinary shares outstanding during each period. Diluted net income per share is computed based on the weighted average number of ordinary shares outstanding during the period, plus potential dilutive shares considered outstanding during the period, in accordance with ASC 260-10, as determined under the treasury stock method.

s. Income taxes:

The Company accounts for income taxes in accordance with ASC 740-10, "Income Taxes." ASC 740-10 prescribes the use of the liability method whereby deferred tax asset and liability account balances are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, to reduce deferred tax assets to their estimated realizable value, if needed.

The Company established reserves for uncertain tax positions based on the evaluation of whether or not the Company’s uncertain tax position is "more likely than not" to be sustained upon examination. The Company records interest and penalties pertaining to its uncertain tax positions in the financial statements as income tax expense.

t. Concentration of risks:

Our cash, cash equivalents, short-term investments and trade receivables are potentially subject to a concentration of risk. Cash, cash equivalents and short-term investments are invested at top tier financial institutions globally. As

80

Table of Contents

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

such, these investments may be in excess of insured limitations or not insured in certain jurisdictions. Generally, these investments may be redeemed upon demand and therefore, bear minimal risk.

The Company has no off-balance sheet concentrations of credit risk such as foreign exchange contracts, option contracts or other foreign hedging arrangements.

u. Retirement, pension and severance plans:

The Company has a 401(k) retirement savings plan for its U.S. employees. Each eligible employee may elect to contribute a portion of the employee’s compensation to the plan. Company contributions to the plan are at the sole discretion of the Company's Board of Directors. Currently, the Company provides a matching contribution of 50% of the employee's contributions, up to a maximum of three percent (3%) of the employee's annual salary. The Company began making matching contributions as of January 1, 2019. For the years ended December 31, 2020 and 2019, the Company had made matching contributions in the amount of $1,589 and $978, respectively, pursuant to the plan.

The Company sponsors a defined benefit plan (the "Swiss Plan") for all its employees in Switzerland for retirement benefits, as well as benefits on death or long-term disability, whereby the employee and the Company contribute a portion of the employee's compensation to the plan. The Swiss Plan is part of a collective pension foundation “Asga Pensionskasse.” Asga is an autonomous pension foundation, meaning that the underlying investment risk and all biometrical risks (disability, death, longevity) are born by the pension foundation itself. Notwithstanding, the Company and its employees bear the risk of having to pay recovery contributions in a financial distress situation. The Company accounts for this risk in accordance with ASC 715, "Compensation – Retirement Benefits" (see Note 9). The pension expense for the years ended December 31, 2020, 2019 and 2018 was $1,588, $984 and $882, respectively.

Israeli law generally requires payment of severance pay upon dismissal of an employee or upon termination of employment in certain other circumstances. The Company contributes to employee pension plans to fund its severance liabilities. According to Section 14 of Israel Severance Pay Law, the Company makes deposits on behalf of its employees with respect to the Company’s severance liability and therefore no obligation is provided for in the financial statements. Severance pay liabilities with respect to employees who are not subject to Section 14, are provided for in the financial statements based upon the number of years of service and the latest monthly salary and the related deposits are recorded as an asset based on the cash surrender value. Contributions pursuant to these obligations for the years ended December 31, 2020, 2019 and 2018 amounted to $1,130, $784 and $526, respectively.

v. Contingent liabilities:

The Company accounts for its contingent liabilities in accordance with ASC 450, "Contingencies." A provision is recorded when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

With respect to legal matters, provisions are reviewed and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter.

w. Other comprehensive income (loss):

The Company accounts for comprehensive income (loss) in accordance with ASC 220, "Comprehensive Income." ASC 220 establishes standards for the reporting and display of comprehensive income (loss) and its components. Comprehensive income (loss) generally represents all changes in shareholders' equity during the period except those resulting from investments by, or distributions to, shareholders. The accumulated other comprehensive income (loss), net of taxes, relates to a pension liability and foreign currency translation adjustments.

x. Leases:

1.Lessee accounting:

On January 1, 2019, the Company adopted ASU No. 2016-02, Leases (ASC 842). The Company determines if an arrangement is a lease and the classification of that lease at inception based on: (1) whether the contract involves the use of a distinct identified asset, (2) whether the Company obtains the right to substantially all the economic

81

Table of Contents

NovoCure Limited and subsidiaries

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

benefits from the use of the asset throughout the period, and (3) whether the Company has a right to direct the use of the asset. The Company elected to not recognize a lease liability or right-of-use ("ROU") asset for leases with a term of twelve months or less. The Company also elected the practical expedient to not separate lease and non-lease components for its leases.

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make minimum lease payments arising from the lease. ROU assets are initially measured at amounts, which represents the discounted present value of the lease payments over the lease, plus any initial direct costs incurred. The ROU assets are reviewed for impairment. The lease liability is initially measured at lease commencement date based on the discounted present value of minimum lease payments over the lease term. The implicit rate within the operating leases are generally not determinable; therefore, the Company uses the Incremental Borrowing Rate ("IBR") based on the information available at commencement date in determining the present value of lease payments. The Company’s IBR is estimated to approximate the interest rate on similar terms and payments and in economic environments where the leased asset is located.

Certain leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain that the Company will exercise that option. An option to terminate is considered unless it is reasonably certain that the Company will not exercise the option.

2. Lessor accounting - Operating leases:

ASC 842 provides lessors with an optional practical expedient, by class of underlying asset, not to separate non-lease components from the associated lease component and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under the new revenue guidance (ASC 606) and both of the following criteria are met:

a. The timing and pattern of transfer of the lease component and the non-lease component(s) are the same; and

b. The lease component would be classified as an operating lease if it were accounted for separately.

The Company's product supply agreements include the right to use the device (lease component), the supply obligation of disposable arrays and technical support for the term of treatment (non-lease component).

If the lease component is the predominant component, the Company accounts for all revenues under such lease as a single component in accordance with the new lease accounting standard. Conversely, if the non-lease component is the predominant component, all revenues under such lease are accounted for in accordance with the revenue recognition accounting standard. The Company's operating leases qualify for the single component accounting, and the non-lease component in each of the Company's leases is predominant. Therefore, The Company accounts for all revenues from its operating leases in accordance with the revenue recognition accounting standard.

y. Convertible note:

The Company accounts for its convertible senior notes in accordance with ASC 470-20 "Debt with Conversion and Other Options". Pursuant to ASC Subtopic 470-20, issuers of certain convertible debt instruments, such as the convertible senior notes, that have a net settlement feature and may be settled wholly or partially in cash upon conversion are required to separately account for the liability (debt) and equity (conversion option) components of the instrument. The Company allocated the proceeds from issuance between the liability component and the embedded conversion option, or equity component. The liability component at issuance is recognized at fair value, based on the fair value of a similar instrument of similar credit rating and maturity that does not have a conversion feature. The equity component is based on the excess of the principal amount of the convertible senior notes over the fair value of the liability component and is recorded in additional paid-in capital. The equity component, net of issuance costs is presented within additional paid-in-capital and is not remeasured as long as it continues to meet the conditions for equity classification. The Company allocated the total issuance costs incurred to the liability and equity components of the convertible senior notes based on the same proportions as the proceeds from the notes.

z. Recently adopted accounting pronouncements:

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

82

Table of Contents

NovoCure Limited and subsidiaries

Notes to consolidated financial statements

U.S. dollars in thousands (except share and per share data)

(“ASU 2016-13”). ASU 2016-13 amends the impairment model to utilize an expected loss methodology in place of the currently used incurred loss methodology, which will result in the more timely recognition of losses, with an effective date for the first quarter of fiscal year 2020. The Company adopted the standard effective as of January 1, 2020 and the adoption of this standard did not have an impact on the Company's consolidated financial statements.

In August 2018, FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The implementation costs incurred in a hosting arrangement that is a service contract should be presented as a prepaid asset in the balance sheet and expensed over the term of the hosting arrangement to the same line item in the statement of income as the costs related to the hosting fees. The Company adopted the standard effective as of January 1, 2020 and the adoption of this standard did not have an impact on the Company's consolidated financial statements.

aa. Recently issued accounting pronouncements:

In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (ASU 2020-06), which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. Among other changes, ASU 2020-06 removes from GAAP the liability and equity separation model for convertible instruments with a cash conversion feature, and as a result, after adoption, entities will no longer separately present in equity an embedded conversion feature for such debt. Similarly, the embedded conversion feature will no longer be amortized into income as interest expense over the life of the instrument. Instead, entities will account for a convertible debt instrument wholly as debt unless (1) a convertible instrument contains features that require bifurcation as a derivative under ASC Topic 815, Derivatives and Hedging, or (2) a convertible debt instrument was issued at a substantial premium. Among other potential impacts, this change is expected to reduce reported interest expense, increase reported net income, and result in a reclassification of certain conversion feature balance sheet amounts from stockholders’ equity to liabilities as it relates to the Company’s convertible senior notes. Additionally, ASU 2020-06 requires the application of the if-converted method to calculate the impact of convertible instruments on diluted earnings per share (EPS), which is consistent with the Company’s accounting treatment under the current standard. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020, and can be adopted on either a fully retrospective or modified retrospective basis. The Company early adopted ASU 2020-06, effective January 1, 2021. See Note 20 for the impact of this adoption.

In December 2019, the FASB issued Accounting Standard Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). This guidance will be effective for the Company in the first quarter of 2021 on a prospective basis, and early adoption is permitted. As of December 31, 2020 the Company had not early adopted ASU 2019-12. The Company is evaluating the potential effect of the new guidance and believes there will be no material impact to the consolidated financial statements.

actuarial present value of the estimated future payments required to settle the obligation that is attributable to employee service rendered before that date. Swiss Plan assets are recorded at fair value. Pension expense is presented in the payroll expenses in the various functions in which the employees are engaged. Actuarial gains and losses arising from differences between the actual and the expected return on the Swiss Plan assets are recognized in accumulated other comprehensive income (loss) and amortized over the requisite service period. The Swiss Plan is part of a collective pension foundation of pooled investments managed by a top tier insurance company. The Company and the employees pay retirement contributions, which are defined as a percentage of the employees’ covered salaries. Interest is credited to the employees’ account at the minimum rate provided in the Swiss Plan, which represents the Swiss Plan’s primary asset. The targeted allocation for these funds is as follows:

December 31,

0% Convertible Senior Notes (a) $ 429,905 $ —

a.Convertible note

On November 5, 2020, the Company issued $575,000 aggregate principal amount of 0% Convertible Senior Notes due 2025 (the “Notes”). The net proceeds from the offering were approximately $558,400.

The Notes are senior unsecured obligations of the Company. The Notes do not bear regular interest, and the principal amount of the Notes will not accrete. Special interest, if any, payable in accordance with the terms of the Notes will be payable in cash semi-annually in arrears on May 1 and November 1 of each year, beginning on May 1, 2021. The Notes mature on November 1, 2025, unless earlier repurchased, redeemed or converted.

The Notes are convertible into cash, the Company’s ordinary shares or a combination of cash and the Company’s ordinary shares at the Company’s election at an initial conversion rate of 5.9439 ordinary shares per $1,000 principal amount of the Notes, which is equivalent to an initial conversion price of approximately $168.24 per ordinary share. For additional information see note 20.

The Notes are not redeemable prior to November 6, 2023, except in the event of certain tax law changes. The Company may redeem for cash all or any portion of the Notes, at the Company’s option, on or after November 6, 2023 if the last reported sale price of the Company’s ordinary shares has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid special interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes.

Prior to the close of business on the business day immediately preceding August 1, 2025, the Notes are convertible at the option of the holders only upon the satisfaction of certain conditions and during certain periods as described below and if the Company exercises its right to redeem the Notes as permitted or required by the Indenture as described below. On or after August 1, 2025 until the close of the business on the business day immediately preceding the maturity date, holders may convert all or any portion of their Notes at the conversion rate at any time irrespective of the foregoing conditions.

If holders of at least $3,000 aggregate principal amount of the Notes provide the Company with reasonable evidence that the trading price per $1,000 principal amount of Notes (the “Note Trading Price”) on any trading day would be less than 98% of the product of the last reported sale price of the Ordinary Shares on such trading day and the conversion rate on such trading day (the “Trigger Note Price”), the Company shall follow the process for obtaining the Note Trading Price as provided in the Indenture on a daily basis until the Note Trading Price exceeds the Trigger Notice Price. During this time, if during any five consecutive trading day period (the “Measurement Period”) the Note Trading Price is less than 98% of the Trigger Notice Price, the Company must notify the holders and the trustee of such an event and the holders may convert their Notes into Ordinary Shares at any time during the five business day period immediately after.

If the Company intends to (i) issue warrants/rights/options to existing shareholders with an exercise price less than the ten-day trailing last trading price average or (ii) distribute to shareholders assets, securities or rights with a value per share greater than 10% of the last reported trading price, then the Company must give holders of the Notes thirty-five (35) trading days’ notice of such event, at which time a holder may convert their Notes during such 35 trading day period (or until the Company revokes its decision to issue/distribute the securities, whichever comes sooner).

In addition, upon the occurrence of a fundamental change (as defined in the indenture), holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid special interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event or notice of redemption, as the case may be.

During the year ended December 31, 2020, the conditions allowing holders of the Notes to convert were not met. The Notes are therefore not convertible as of December 31, 2020 and are classified as long-term liability.

The net carrying amount of the liability and equity components of the Convertible Notes as of December 31, 2020 is as follows:

December 31,

Liability component, net:

Unamortized issuance costs (12,298)

Net carrying amount of liability component (1) $ 429,905

Equity component, net:

Issuance costs (3,928)

Net carrying amount of equity component $ 132,473

(1) An effective interest rate determines the fair value of the Notes, therefore they are categorized as Level 3 in accordance with ASC 820, "Fair Value Measurements and Disclosures." The estimated fair value of the Net carrying amount of liability component of the Notes as of December 31, 2020 was $450,437.

Finance expense related to the Convertible Notes was as follows:

Year ended December 31,

Amortization of debt discount $ 3,604

Amortization of debt issuance costs 334

Total finance expense recognized $ 3,938

b. Loan and Security Agreement

On February 7, 2018, the Company and certain of its subsidiaries entered into a Loan and Security Agreement ("2018 Loan Agreement") with BioPharma Credit PLC pursuant to which such lender made a term loan to the Company in the principal amount of $150,000 (the "2018 Credit Facility"). The term loan, which was drawn in full upon execution of the 2018 Loan Agreement, bore interest at 9.0% per annum, payable quarterly in arrears.

On August 18, 2020, the Company terminated the 2018 Credit Facility. The prepayment included $150,000 in principal repayment and $3,000 in prepayment premium, plus accrued and unpaid interest and expenses payable through the payoff date. The un-amortized issuance costs in the amount of $478 that were fully amortized upon the repayment and the prepayment premium were reported in the Company’s finance expenses.

a.Operating leases

The facilities of the Company are leased under various operating lease agreements for periods ending no later than 2030. The Company also has the option to extend the term of certain facility lease agreements and these are included in the calculation of right-of-use assets. The Company also leases motor vehicles under various operating leases, which expire on various dates, the latest of which is in 2024.

Under ASC 842, all leases with durations greater than 12 months, including non-cancelable operating leases, are recognized on the balance sheet. The aggregated present value of lease agreements, net of deferred rent, is recorded as a long-term asset titled right-of-use assets. The corresponding lease liabilities are split between other payables and long-term lease liabilities.

Upon implementation of ASC 842, effective January 1, 2019, the Company recorded an increase in right-of-use assets obtained in exchange for lease obligations of $15,733 on our opening balance sheet. Future minimum lease payments under non-cancelable operating leases as of December 31, 2020, are as follows:
