NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

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

NOTE 1: ORGANIZATION AND BASIS OF PRESENTATION

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 delivery systems, including Optune and NovoTTF-100L, for the treatment of solid tumors. The Company has received regulatory approval from the U.S. Food and Drug Administration (“FDA”) under the Premarket Approval pathway and regulatory approvals and clearances in certain other countries for Optune to treat adult patients with GBM.  The Company also has received FDA approval under the Humanitarian Device Exemption pathway to market NovoTTF-100L for unresectable, locally advanced or metastatic MPM in combination with standard chemotherapies.

Financial statement preparation. The accompanying consolidated financial statements include the accounts of the Company and intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation for the periods presented. The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. These consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “2018 10-K”) filed with the Securities and Exchange Commission on February 28, 2019.

The significant accounting policies applied in the audited annual consolidated financial statements of the Company as disclosed in the 2018 10-K are applied consistently in these unaudited interim consolidated financial statements, except as noted below:

Recently Adopted Accounting Pronouncements. In 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, which amends the existing standards for lease accounting, requiring lessees to recognize most leases on their balance sheets. The new standard establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating. The standard is effective for interim and annual reporting periods beginning after December 15, 2018.

The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, “Targeted Improvements - Leases (Topic 842)” (together with ASU 2016-02, “ASC 842”). This update provides an additional (and optional) transition method to adopt the new leases standard. Under this method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the prior comparative period’s financials will remain the same as those previously presented. The Company adopted the new standard as of January 1, 2019 and it has also elected to adopt the package of practical expedients permitted in ASC 842.

ASC 842 provides lessors with a 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 (Topic 606). Our product supply agreements include the right to use the device (lease component), the supply obligation of disposable transducer arrays and technical support for the term of treatment (non-lease component). As the non-lease component(s) associated with the lease component is the predominant component of the combined component, the Company accounts for the combined component in accordance with Topic 606.

The consolidated financial statements for the three and nine months ended September 30, 2019 are presented under the new standard, while comparative year and other periods presented are not adjusted and continue to be reported in accordance with Topic 840, Leases.

NOTE 4: COMMITMENTS, RIGHTS OF USE AND CONTINGENT LIABILITIES

Operating Leases and Rights of Use. The facilities of the Company are leased under various operating lease agreements for periods, including options for extensions, ending no later than 2029. The Company also leases motor vehicles under various operating leases, which expire on various dates, the latest of which is in 2022.

Under ASC 842, all leases with durations greater than 12 months, including non-cancelable operating leases, are now 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.

11

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. Lease and rental payments for the nine months ended September 30, 2019, totaled $3,799. Future minimum lease payments under non-cancelable operating leases as of September 30, 2019, are as follows:

NOTE 5: SHARE CAPITAL

In September 2015, the Company adopted the 2015 Omnibus Incentive Plan (the “2015 Plan”). Under the 2015 Plan, the Company can issue various types of equity compensation awards such as share options, restricted shares, performance shares, restricted stock units (“RSUs”), performance units, long-term cash awards and other share-based awards.

Options granted under the 2015 Plan generally have a four-year vesting period and expire ten years after the date of grant. Options granted under the 2015 Plan that are canceled or forfeited before expiration become available for future grants. RSUs granted under the 2015 Plan generally vest over a three-year period. RSUs granted under the 2015 Plan that are canceled before expiration become available for future grants. As of September 30, 2019, 11,915,754 ordinary shares were available for grant under the 2015 Plan.

12

A summary of the status of the Company’s option plans as of September 30, 2019 and changes during the period then ended is presented below: 

	Nine months ended September 30, 2019

In September 2015, the Company adopted an employee share purchase plan (“ESPP”) to encourage and enable eligible employees to acquire ownership of the Company’s ordinary shares purchased through accumulated payroll deductions on an after-tax basis. In the United States, the ESPP is intended to be an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code and the provisions of the ESPP are construed in a manner consistent with the requirements of such section. As of September 30, 2019, 3,078,989 ordinary shares were available to be purchased by eligible employees under the ESPP and 390,614 shares had been issued under the ESPP.

13

The fair value of share-based awards was estimated using the Black-Scholes model for all equity grants. For market condition awards, the Company also applied the Monte-Carlo simulation model. We assessed fair value using the following underlying assumptions: 

	Nine months ended September 30,				Year ended December 31, 2018
	2019		2018

NOTE 6: EARNINGS 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. Basic and diluted net loss per ordinary share was the same for each period presented, except for the three months ended September 30, 2019, as the inclusion of all potential dilutive shares (deriving from options, RSUs and the ESPP) outstanding would be anti-dilutive.

The calculation of diluted earnings per share includes the weighted average of potentially dilutive securities, which consists of ordinary shares underlying outstanding share options, RSUs and the ESPP. The effect of these dilutive securities under the treasury stock method was approximately 9,119,059 shares for the three months ended September 30, 2019.

The Company excluded 57,782 share options from the computation of dilutive net income per share for the three months ended September 30, 2019 because including them would had have an anti-dilutive effect.

Item 2.  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 for the period ended September 30, 2019 included in Part I, Item 1 of this Quarterly Report on Form 10-Q. 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, the use of electric fields tuned to specific frequencies to disrupt solid tumor cancer cell division. Our key priorities are to drive adoption of Optune and the NovoTTF-100L System (“NovoTTF-100L”), our commercial Tumor Treating Fields delivery systems, and to advance programs testing the safety and efficacy of our products in multiple solid tumor indications through our clinical pipeline.

We have built a commercial organization in the United States, Austria, Germany, Israel, Japan, Sweden and Switzerland, which we refer to as our currently active markets. 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 glioblastoma (“GBM”) in combination with temozolomide, a chemotherapy drug, and for use as monotherapy treatment for adult patients with GBM following confirmed recurrence after chemotherapy. We also have approval to market Optune for the treatment of GBM in the European Union, Japan and certain other countries.

We continue to work with payers to expand access to Optune for patients with GBM. As of September 30, 2019, a substantial majority of Americans with private health insurance had coverage of Optune for newly diagnosed and/or recurrent GBM. Effective as of September 1, 2019, Americans who are beneficiaries of the Medicare fee-for-service program also have coverage of Optune for newly diagnosed GBM. Our team is focused on working through the typical administrative ramp-up with Medicare to ensure that we realize the full financial benefit as soon as possible. We are actively appealing Medicare fee-for-service coverage denials up to and including the Administrative Law Judge (“ALJ”) process with Centers for Medicare and Medicaid Services (“CMS”).

In June 2019, the German Institute for Quality and Efficiency in Healthcare (“IQWiG”), published its rapid report concluding that, based on a review of our EF-14 phase 3 pivotal trial, patients with newly diagnosed GBM lived longer when treated with Optune in addition to standard chemotherapy, without affecting quality of life. According to the published timeline, we now expect a national reimbursement decision in Germany no later than October 2020.

As of September 30, 2019, the total number of contracted lives globally was more than 407 million.

In order to further advance the scientific evidence supporting the use of Optune in GBM and gather additional information about Optune’s optimal use, we plan to initiate additional randomized trials in GBM. The first trial, which we plan to begin in the next few months, will be a post-marketing trial designed to study the potential benefit of earlier initiation of Optune, concurrent with radiation therapy, versus initiation post radiation, and is intended to support possible label expansion. A second trial, which we plan to begin in 2020, is currently being designed.

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.

In May 2019, NovoTTF-100L received approval by the FDA under the Humanitarian Device Exemption (“HDE”) pathway to treat unresectable, locally advanced or metastatic malignant pleural mesothelioma (“MPM”) in combination with standard chemotherapies based upon the results of our STELLAR trial. In October 2019, results from our STELLAR trial were published in The Lancet Oncology. We have initiated a phased launch for MPM shaped by our learnings from our GBM rollout.  Our initial launch efforts are focused on certifying radiation oncologists and on supporting the required Institutional Review Board (“IRB”) approval process at the approximately 40 centers that we believe see the majority of U.S. MPM patients. As of September 30, 2019, prescribers were certified at 10 centers across the U.S. and two centers had successfully completed the required IRB approval process. The first MPM commercial patient started therapy in September 2019. We are currently exploring the appropriate regulatory pathway for MPM in our currently active markets outside of the U.S.

16

We expect to begin a dialogue with payers around access to NovoTTF-100L for patients with MPM in future quarters. We anticipate that MPM claims during the early launch phase will go through an appeal process with payers, similar to our early experience with GBM.

In March 2019, we enrolled the first patient in our ENGOT-ov50/INNOVATE-3 trial, a phase 3 pivotal trial testing the effectiveness of Tumor Treating Fields with paclitaxel in patients with recurrent, platinum-resistant ovarian cancer. The protocol specifies overall survival as primary endpoint and an event-driven interim analysis, which we anticipate will occur in 2022. The European Network for Gynaecological Oncological Trial groups (“ENGOT”) and The GOG Foundation, Inc. (“GOG”), third-party clinical trial networks, are collaborating with us on the trial.  ENGOT and GOG were involved in the development of the trial and the collaborations are intended to facilitate enrollment of INNOVATE-3 at leading cancer centers in Europe and the United States.

Currently, we are conducting phase 3 pivotal trials evaluating the use of Tumor Treating Fields in brain metastases, non-small-cell lung cancer, pancreatic cancer and ovarian cancer. We are also conducting a phase 2 pilot trial evaluating the use of Tumor Treating Fields in liver cancer. We anticipate expanding our clinical pipeline over time to study the safety and efficacy of Tumor Treating Fields for additional solid tumor indications.

The table below presents the current status of the ongoing or completed clinical trials in our pipeline and our expected next milestone for each. We now expect data from the HEPANOVA phase 2 pilot trial in 2021.

We believe we have a diverse intellectual property portfolio that includes over 145 issued patents and pending patent applications as well as numerous trade secrets. We believe these intellectual property assets provide expansive commercialization rights to our products in the oncology space.

In 2018, we granted Zai Lab (Shanghai) Co., Ltd. (“Zai”) a license to commercialize Optune in China, Hong Kong, Macau and Taiwan under a License and Collaboration Agreement (the “Zai Agreement”). The Chinese regulatory authorities designated Optune as an Innovative Medical Device and have accepted the Marketing Authorization Application for the GBM indication in China. Zai is pursuing a clinical trial waiver and, should a clinical trial waiver be granted, Zai intends to launch Optune in China before the end of 2019. On the clinical development front, Zai is working to finalize the protocol for a phase 2 pilot trial in gastric cancer and is collaborating closely with our clinical teams to initiate trials in other key indications in China.

Financial Overview. We view our operations and manage our business in one operating segment. For the three and nine months ended September 30, 2019, our net revenues were $92.1 million and $252.1 million, respectively. Our net income (loss) for the three and nine months ended September 30, 2019 was $1.9 million and $(11.5) million, respectively. As of September 30, 2019, we had an accumulated deficit of $655.1 million.

Critical Accounting Policies and Estimates

In accordance with U.S. generally accepted accounting principles (“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 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 can be found in our Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “2018 10-K”). For additional information, see Note 1 to our Unaudited Consolidated Financial Statements. There were no other material changes to our critical accounting policies and estimates as compared to the critical accounting policies and estimates described in our 2018 10-K.

Commentary on Results of Operations

Net revenues. Our revenues are primarily derived from patients using Optune in our currently active markets. We charge for treatment with Optune and NovoTTF-100L 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 recognized revenue pursuant to the Zai Agreement in each quarter of 2019. For additional information regarding the Zai Agreement, see Note 12 to the Consolidated Financial Statements in our 2018 10-K.

Cost of revenues. We contract with third-party manufacturers that manufacture our products. Our cost of revenues is primarily comprised of the following:

•disposable transducer arrays;

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

•personnel, warranty 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.

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.

1.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.

18

2.A “prescription received” is a commercial order for Optune or NovoTTF-100L that is received from a physician certified to treat patients for a patient not previously on Optune or NovoTTF-100L. Orders to renew or extend treatment are not included in this total.

Prescriptions for newly diagnosed GBM represented 82% of total prescriptions for the three months ended September 30, 2019, compared to 75% for the same period in 2018.

Three months ended September 30, 2019 compared to three months ended September 30, 2018

	Three months ended September 30,
	2019		2018		Change		% Change
Net revenues	$	92,062	$	64,756	$	27,306	42	%

Net revenues. Net revenues increased $27.3 million, or 42%, to $92.1 million for the three months September 30, 2019 from $64.8 million for the three months ended September 30, 2018. This was primarily due to an increase of 499 active patients in our currently active markets, representing 22% growth, and an improvement in the net revenues booked per active patient. The increase in net revenues per active patient benefited from continued improvements in reimbursement rates in both the U.S. and EMEA. In addition, under the newly defined coverage policy effective as of September 1, 2019, we recognized the initial benefit from Medicare with $0.5 million in third quarter net revenues.

	Three months ended September 30,
	2019		2018		Change		% Change
Cost of revenues	$	22,900	$	18,949	$	3,951	21	%

Cost of revenues. Our cost of revenues increased by $4.0 million, or 21%, to $22.9 million for the three months ended September 30, 2019 from $18.9 million for the three months ended September 30, 2018. The increase in cost of revenues was primarily due to the cost of shipping transducer arrays to a higher volume of commercial patients partially offset by a reduction in the cost of goods per active patient driven by ongoing efficiency initiatives and scale. Gross margin was 75% for the three months ended September 30, 2019 and 71% for the three months ended September 30, 2018.

Operating Expenses.

	Three months ended September 30,

Total operating expenses	$	65,307	$	51,053	$	14,254	28	%

Research, development and clinical trials expenses. Research, development and clinical trials expenses increased $5.7 million, or 44%, to $18.8 million for the three months ended September 30, 2019 from $13.1 million for the three months ended September 30, 2018. The change is primarily due to an increase in clinical trial and personnel expenses for our phase 3 pivotal trials and an increase in costs associated with medical affairs, regulatory matters and engineering.

Sales and marketing expenses. Sales and marketing expenses increased $4.7 million, or 25%, to $23.8 million for the three months ended September 30, 2019 from $19.1 million for the three months ended September 30, 2018. The change was primarily due to increased marketing expenses and personnel costs to support our growing commercial business.

General and administrative expenses. General and administrative expenses increased $3.9 million, or 20%, to $22.7 million for the three months ended September 30, 2019 from $18.9 million for the three months ended September 30, 2018. The change was primarily due to an increase in personnel costs and an increase in professional services.

Income taxes. Income taxes decreased $4.7 million, or 116%, to a benefit of $0.6 million for the three months ended September 30, 2019 from $4.1 million for the three months ended September 30, 2018. The change was primarily a result of the mix of applicable statutory tax rates in certain active jurisdictions. We also recorded an income tax benefit of approximately $1.5 million in the quarter ended September 30, 2019 as a result of research and development credits claimed in the U.S.

Nine months ended September 30, 2019 compared to nine months ended September 30, 2018

	2019		2018		Change		% Change
Net revenues	$	252,084	$	178,395	$	73,689	41	%

Net revenues. Net revenues increased $73.7 million, or 41%, to $252.1 million for the nine months ended September 30, 2019 from $178.4 million for the nine months ended September 30, 2018. This was primarily due to an increase of 499 active patients in our currently active markets, representing 22% growth, and an improvement in the net revenues booked per active patient.

	Nine months ended September 30,
	2019		2018		Change		% Change
Cost of revenues	$	63,820	$	57,020	$	6,800	12	%

Cost of revenues. Our cost of revenues increased by $6.8 million, or 12%, to $63.8 million for the nine months ended September 30, 2019 from $57.0 million for the nine months ended September 30, 2018. The increase in cost of revenues was primarily due to the cost of shipping transducer arrays to a higher volume of commercial patients partially offset by a reduction in the cost of goods per active patient driven by ongoing efficiency initiatives and scale. Gross margin was 75% for the nine months ended September 30, 2019 and 68% for the nine months ended September 30, 2018.

Operating Expenses.

Total operating expenses	$	189,331	$	146,383	$	42,948	29	%

Research, development and clinical trials expenses. Research, development and clinical trials expenses increased $19.7 million, or 55%, to $55.3 million for the nine months ended September 30, 2019 from $35.5 million for the nine months ended September 30, 2018. The change is primarily due to an increase in clinical trial and personnel expenses for our phase 3 pivotal trials and an increase in costs associated with medical affairs, regulatory matters and engineering.

Sales and marketing expenses. Sales and marketing expenses increased $13.4 million, or 24%, to $69.9 million for the nine months ended September 30, 2019 from $56.5 million for the nine months ended September 30, 2018. The change was primarily due to increased marketing expenses related to the launch of NovoTTF-100L for MPM and increases in our personnel costs associated with a larger sales force globally.

General and administrative expenses. General and administrative expenses increased $9.8 million, or 18%, to $64.2 million for the nine months ended September 30, 2019 from $54.4 million for the nine months ended September 30, 2018. The change was primarily due to an increase in personnel costs and an increase in professional services.

Financial expenses (income), net	$	6,165	$	10,110	$	(3,945)	(39)	%

Financial expenses decreased $3.9 million, or 39%, to $6.2 million for the nine months ended September 30, 2019 from $10.1 million for the nine months ended September 30, 2018. The change was primarily due to the 2018 accelerated amortization costs triggered by the repayment of our 2015 term loan credit facility, interest income and the favorable impact of foreign exchange, partially offset by interest expenses on our new $150 million term loan credit facility. For additional information, see Note 10 to our Consolidated Financial Statements in our 2018 10-K.

We also recorded an income tax benefit of approximately $1.5 million in the quarter ended September 30, 2019 as a result of research and development credits claimed in the U.S.

Liquidity and Capital Resources

We have incurred significant losses and cumulative negative cash flows from operations since our founding in 2000. As of September 30, 2019, we had an accumulated deficit of $655.1 million. To date, we have primarily financed our operations through the issuance and sale of equity and the proceeds from long-term loans. At September 30, 2019, we had $312.6 million in cash, cash equivalents and short-term investments, an increase of $66.7 million compared to $245.9 million at December 31, 2018. The increase in our cash, cash equivalents and short-term investments was primarily due to cash flow from operations and the exercise of options.

We believe our cash, cash equivalents and short-term investments as of September 30, 2019 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 anticipate continuing to incur significant costs associated with commercializing our products for approved indications. We expect our research and development expenses to increase in connection with our ongoing activities and as we continue to fund investments in our clinical pipeline and technology development. Such expenses may outpace our gross profit. As a result, we may need to raise additional capital to fund our operations.

Sources of Liquidity

Since inception, we have financed our operations primarily through the issuance and sale of equity and the proceeds from long-term loans. As of September 30, 2019, we had received a total of $839.8 million from these activities.      

	Nine months ended September 30,
	2019		2018		Change		% Change
Net cash provided by (used in) operating activities	$	19,658	$	(18,679)	$	38,337	(205)	%

Operating activities. Net cash provided by (used in) operating activities primarily represents our net income (loss) for the periods presented. Adjustments to net income (loss) for non-cash items include share-based compensation, depreciation and amortization, accrued interest and impairments. Operating cash flows are also impacted by changes in working capital, principally trade receivables, prepaid expenses, inventories, trade payables and accrued expenses.

Net cash provided by operating activities was $19.7 million for the nine months ended September 30, 2019, as compared to $18.7 million used in operating activities for the nine months ended September 30, 2018. Gross profit increased by $66.9 million for the nine months ended September 30, 2019 versus the nine months ended September 30, 2018, fully funding incremental investments of $19.7 million in research and development and $23.2 million in sales, marketing, general and administrative expenses. The transition to positive cash flow from operations, with a $38.3 million increase in cash provided by operating activities, was primarily driven by a decrease in net loss, an increase in share-based compensation and an increase in trade receivables.

	2019	2018	Change		% Change
Net cash provided by (used in) investing activities	(4,911)	(3,704)	$	(1,207)	33	%

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 $4.9 million for the nine months ended September 30, 2019, compared to $3.7 million for the nine months ended September 30, 2018. The increased net cash used in investing activities was primarily attributable to the purchase of property and equipment to support our growing commercial business partially offset by net proceeds generated from the sale of investments for cash needs.

	Nine months ended September 30,
	2019	2018	Change		% Change
Net cash provided by (used in) financing activities	53,095	66,804	$	(13,709)	(21)	%

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 $53.1 million for the nine months ended September 30, 2019, as compared to $66.8 million for the nine months ended September 30, 2018. The year-over-year decrease in cash provided by financing activities was primarily related to the 2018 principal amount of our credit facility and partially offset by proceeds from the exercise of options.

Our material outstanding indebtedness consists of our term loan credit facility. As of September 30, 2019, the aggregate principal balance of amounts outstanding under the term loan credit facility was $150.0 million. We may prepay the term loan, in full, at any time. We must prepay the term loan (i) in full or in part upon the entry into certain licensing arrangements and (ii) in full in the event of a change of control. In each case, any prepayment (whether permitted or mandatory) is subject to a prepayment premium and/or make-whole payment. The prepayment fee if we prepay outstanding loan amounts prior to February 7, 2021 is 2.0% and is 1.0% if made after the February 7, 2021 but prior to February 7, 2022. If we prepay outstanding loan amounts prior to August 7, 2020, we must pay a make-whole amount equal to the amount of interest that would have accrued on the amount of all principal we prepaid from the date of such prepayment through February 7, 2021.

All obligations under the term loan credit facility are guaranteed by certain of our current and future domestic direct and indirect subsidiaries. In addition, the obligations under the term loan credit facility are secured by a first-priority security interest in substantially all of the property and assets of, as well as the equity interests owned by, us and the other guarantors. The term loan credit facility contains other customary covenants.

Contractual Obligations and Commitments

There have been no material changes from the information disclosed in our 2018 10-K.

Off-Balance Sheet Arrangements

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

There have been no material changes from the information disclosed in our 2018 10-K.

Item 4.  Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2019. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a

22

company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2019, our Chief Executive Officer and Chief Financial Officer have concluded that, as of September 30, 2019, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the quarter ended September 30, 2019 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1.  Legal Proceedings

There have been no material changes to our legal proceedings disclosed in the 2018 10-K except as noted below.

In February 2019, a civil claim was filed in the District Court in Haifa, Israel (the “Court”), by Ofir Paz (“Paz”), a former member of our Board of Directors, and EES Investments Ltd., a company wholly owned by Paz (together with Paz, “Plaintiff”) against us and Prof. Yoram Palti (“Respondents”). Plaintiff claims that he is entitled to 210,000 ordinary shares (adjusted for share capital splits since 2003) from Respondents pursuant to an alleged 2003 verbal agreement between Plaintiff and Prof. Palti, who was also a member of our Board of Directors at that time, for Plaintiff’s contribution to the advancement of our business and the consummation of a third party investment in our company. In May 2019, we filed a motion to dismiss the claim that is still pending. In September 2019, Plaintiff filed a motion to amend the claim, requesting that Asaf Danziger be added as a Respondent. That motion is still pending. We believe that the complaint is without merit and plan to defend against this claim vigorously. We have not accrued any amounts in respect of these claims, as we believe liability is not probable and the amount of any potential liability cannot be reasonably estimated.

Item 1A.  Risk Factors

There have been no material changes to our risk factors disclosed in Part I, Item 1A “Risk Factors” to our Form 10-Q filed with the Securities and Exchange Commission on July 25, 2019.

Earnings Per Share [Abstract]

Earnings Per Share

EARNINGS 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. Basic and diluted net loss per ordinary share was the same for each period presented, except for the three months ended September 30, 2019, as the inclusion of all potential dilutive shares (deriving from options, RSUs and the ESPP) outstanding would be anti-dilutive.

The calculation of diluted earnings per share includes the weighted average of potentially dilutive securities, which consists of ordinary shares underlying outstanding share options, RSUs and the ESPP. The effect of these dilutive securities under the treasury stock method was approximately 9,119,059 shares for the three months ended September 30, 2019.

The Company excluded 57,782 share options from the computation of dilutive net income per share for the three months ended September 30, 2019 because including them would had have an anti-dilutive effect.

Organization and Basis of Presentation

ORGANIZATION AND BASIS OF PRESENTATION

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 delivery systems, including Optune and NovoTTF-100L, for the treatment of solid tumors. The Company has received regulatory approval from the U.S. Food and Drug Administration (“FDA”) under the Premarket Approval pathway and regulatory approvals and clearances in certain other countries for Optune to treat adult patients with GBM.  The Company also has received FDA approval under the Humanitarian Device Exemption pathway to market NovoTTF-100L for unresectable, locally advanced or metastatic MPM in combination with standard chemotherapies.

Financial statement preparation. The accompanying consolidated financial statements include the accounts of the Company and intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation for the periods presented. The preparation of these consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in these consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. These consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (the “2018 10-K”) filed with the Securities and Exchange Commission on February 28, 2019.

The significant accounting policies applied in the audited annual consolidated financial statements of the Company as disclosed in the 2018 10-K are applied consistently in these unaudited interim consolidated financial statements, except as noted below:

Recently Adopted Accounting Pronouncements. In 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, which amends the existing standards for lease accounting, requiring lessees to recognize most leases on their balance sheets. The new standard establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating. The standard is effective for interim and annual reporting periods beginning after December 15, 2018.

The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, “Targeted Improvements - Leases (Topic 842)” (together with ASU 2016-02, “ASC 842”). This update provides an additional (and optional) transition method to adopt the new leases standard. Under this method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the prior comparative period’s financials will remain the same as those previously presented. The Company adopted the new standard as of January 1, 2019 and it has also elected to adopt the package of practical expedients permitted in ASC 842.

ASC 842 provides lessors with a 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 (Topic 606). Our product supply agreements include the right to use the device (lease component), the supply obligation of disposable transducer arrays and technical support for the term of treatment (non-lease component). As the non-lease component(s) associated with the lease component is the predominant component of the combined component, the Company accounts for the combined component in accordance with Topic 606.

The consolidated financial statements for the three and nine months ended September 30, 2019 are presented under the new standard, while comparative year and other periods presented are not adjusted and continue to be reported in accordance with Topic 840, Leases.

Share-based Compensation, Allocation and Classification in Financial Statements [Abstract]

Share Capital

SHARE CAPITAL

In September 2015, the Company adopted the 2015 Omnibus Incentive Plan (the “2015 Plan”). Under the 2015 Plan, the Company can issue various types of equity compensation awards such as share options, restricted shares, performance shares, restricted stock units (“RSUs”), performance units, long-term cash awards and other share-based awards.

Options granted under the 2015 Plan generally have a four-year vesting period and expire ten years after the date of grant. Options granted under the 2015 Plan that are canceled or forfeited before expiration become available for future grants. RSUs granted under the 2015 Plan generally vest over a three-year period. RSUs granted under the 2015 Plan that are canceled before expiration become available for future grants. As of September 30, 2019, 11,915,754 ordinary shares were available for grant under the 2015 Plan.

A summary of the status of the Company’s option plans as of September 30, 2019 and changes during the period then ended is presented below: 

	Nine months ended September 30, 2019

Exercisable options	3,444,478	$	14.61

For the nine months, ended September 30, 2019, options to purchase 4,914,918 ordinary shares were exercised, resulting in the issuance of 4,914,918 ordinary shares.

A summary of the status of the Company’s RSUs as of September 30, 2019 and changes during the period then ended is presented below: 

	Nine months ended September 30, 2019

In September 2015, the Company adopted an employee share purchase plan (“ESPP”) to encourage and enable eligible employees to acquire ownership of the Company’s ordinary shares purchased through accumulated payroll deductions on an after-tax basis. In the United States, the ESPP is intended to be an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code and the provisions of the ESPP are construed in a manner consistent with the requirements of such section. As of September 30, 2019, 3,078,989 ordinary shares were available to be purchased by eligible employees under the ESPP and 390,614 shares had been issued under the ESPP.

The fair value of share-based awards was estimated using the Black-Scholes model for all equity grants. For market condition awards, the Company also applied the Monte-Carlo simulation model. We assessed fair value using the following underlying assumptions: 

	Nine months ended September 30,				Year ended December 31, 2018

Commitments, Rights of Use and Contingent Liabilities

COMMITMENTS, RIGHTS OF USE AND CONTINGENT LIABILITIES

Operating Leases and Rights of Use. The facilities of the Company are leased under various operating lease agreements for periods, including options for extensions, ending no later than 2029. The Company also leases motor vehicles under various operating leases, which expire on various dates, the latest of which is in 2022.

Under ASC 842, all leases with durations greater than 12 months, including non-cancelable operating leases, are now 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. Lease and rental payments for the nine months ended September 30, 2019, totaled $3,799. Future minimum lease payments under non-cancelable operating leases as of September 30, 2019, are as follows:

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements. In 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”, which amends the existing standards for lease accounting, requiring lessees to recognize most leases on their balance sheets. The new standard establishes a right-of-use model that requires a lessee to recognize a right-of-use asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases will be classified as finance or operating. The standard is effective for interim and annual reporting periods beginning after December 15, 2018.

The provisions of ASU 2016-02 are to be applied using a modified retrospective approach. In July 2018, the FASB issued ASU No. 2018-11, “Targeted Improvements - Leases (Topic 842)” (together with ASU 2016-02, “ASC 842”). This update provides an additional (and optional) transition method to adopt the new leases standard. Under this method, an entity initially applies the new leases standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Consequently, the prior comparative period’s financials will remain the same as those previously presented. The Company adopted the new standard as of January 1, 2019 and it has also elected to adopt the package of practical expedients permitted in ASC 842.

ASC 842 provides lessors with a 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 (Topic 606). Our product supply agreements include the right to use the device (lease component), the supply obligation of disposable transducer arrays and technical support for the term of treatment (non-lease component). As the non-lease component(s) associated with the lease component is the predominant component of the combined component, the Company accounts for the combined component in accordance with Topic 606.

The consolidated financial statements for the three and nine months ended September 30, 2019 are presented under the new standard, while comparative year and other periods presented are not adjusted and continue to be reported in accordance with Topic 840, Leases.
