ARRAY BIOPHARMA INC.
Notes to the Unaudited Condensed Consolidated Financial Statements



NOTE 1 – OVERVIEW, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Array BioPharma Inc. (also referred to as "Array,","we", "us", "our" or "the Company"), incorporated in Delaware on February 6, 1998, is a biopharmaceutical company focused on the discovery, development and commercialization of targeted small molecule cancer therapies.

The Company formed Yarra Therapeutics, LLC, a Delaware limited liability company ("Yarra"), in anticipation of the contribution by the Company of certain rights and assets related to ARRY-797, including all patents, patent applications and other intellectual property rights, pre-clinical and clinical data, regulatory submissions, inventory, contracts, equipment and books and records related to its ARRY-797 drug program, to Yarra in December 2017. Yarra is currently a wholly-owned subsidiary of Array.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim reporting and, as permitted under those rules, do not include all of the disclosures required by U.S. generally accepted accounting principles ("U.S. GAAP") for complete financial statements. The unaudited condensed consolidated financial statements reflect all normal and recurring adjustments that, in the opinion of management, are necessary to present fairly the Company's financial position, results of operations and cash flows for the interim periods presented. Operating results for an interim period are not necessarily indicative of the results that may be expected for a full year. The Company's management performed an evaluation of its activities through the date of filing of this Quarterly Report on Form 10-Q.

These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited financial statements and the notes thereto for the fiscal year ended June 30, 2017, included in its Annual Report on Form 10-K filed with the SEC on August 11, 2017, from which the Company derived its balance sheet data as of June 30, 2017.

The Company operates in one reportable segment and, accordingly, no segment disclosures have been presented herein. All of the Company's equipment, leasehold improvements and other fixed assets are physically located within the U.S., and the vast majority of its agreements with its partners are denominated in U.S. dollars.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. Management bases its estimates on the Company's historical experience and on various other assumptions that it believes are reasonable under the circumstances. These estimates are the basis for the Company's judgments about the carrying values of assets and liabilities, which in turn may impact its reported revenue and expenses. The Company's actual results could differ significantly from these estimates under different assumptions or conditions.

The Company believes its condensed consolidated financial statements are most significantly impacted by the following accounting estimates and judgments: (i) identifying deliverables under collaboration and license agreements involving multiple elements and determining whether such deliverables are separable from other aspects of the contractual relationship; (ii) estimating the selling price of deliverables for the purpose of allocating arrangement consideration for revenue recognition; (iii) estimating the periods over which the allocated consideration for deliverables is recognized; (iv) estimating accrued outsourcing costs for clinical trials and preclinical testing; and (v) estimating fair value of the notes payable.

Liquidity

With the exception of fiscal year 2015, the Company has incurred operating losses and an accumulated deficit as a result of ongoing research and development spending since inception. As of December 31, 2017, the Company had an accumulated deficit of $990.7 million. The Company had net losses of $34.1 million and $72.0 million for the three and six months ended December 31, 2017 and net losses of $116.8 million and $92.8 million for the fiscal years ended June 30, 2017 and 2016, respectively. The Company had net income of $9.4 million for the fiscal year ended June 30, 2015.

The Company has historically funded its operations from upfront fees, proceeds from research and development reimbursement arrangements, and license and milestone payments received under its drug collaborations and license agreements, the sale of equity securities, and debt provided by convertible debt and other credit facilities. The Company believes that its cash, cash equivalents and marketable securities as of December 31, 2017 will enable it to continue to fund operations in the normal course of business for more than a 12-month period from the date of filing this Quarterly Report on form 10Q. Until the Company can generate sufficient levels of cash from operations, which it does not expect to achieve in at least the next two years, and because sufficient funds may not be available to it when needed from existing collaborations, the Company expects that it will be required to continue to fund its operations in part through the sale of debt or equity securities, and through licensing select programs or partial economic rights that include upfront, royalty and/or milestone payments.

The Company's ability to successfully raise sufficient funds through the sale of debt or equity securities or from debt financing from lenders when needed is subject to many risks and uncertainties and, even if it were successful, future equity issuances would result in dilution to its existing stockholders and any future debt or debt securities may contain covenants that limit the Company’s operations or ability to enter into certain transactions. The Company also may not successfully consummate new collaboration and license agreements that provide for upfront fees or milestone payments or on favorable terms to the Company, or the Company may not earn milestone payments under such agreements when anticipated, or at all. The Company's ability to realize milestone or royalty payments under existing agreements and to enter into new arrangements that generate additional revenue through upfront fees and milestone or royalty payments is subject to a number of risks, many of which are beyond the Company's control.

The Company's assessment of its future need for funding and its ability to continue to fund its operations is a forward-looking statement that is based on assumptions that may prove to be wrong and that involve substantial risks and uncertainties. The Company's actual future capital requirements could vary as a result of a number of factors. These factors include the risk factors disclosed by the Company under the heading "Item 1A. Risk Factors" under Part II of this Quarterly Report on Form 10-Q and under Part I of its Annual Report on Form 10-K for the fiscal year ended June 30, 2017, and in other reports it files with the SEC.

If the Company is unable to generate enough revenue from its existing or new collaboration and license agreements when needed or to secure additional sources of funding and receive related full and timely collections of amounts due, it may be necessary to significantly reduce the current rate of spending through reductions in staff and delaying, scaling back, or stopping certain research and development programs, including more costly late phase clinical trials on its wholly-owned programs. Insufficient liquidity may also require the Company to relinquish greater rights to product candidates at an earlier stage of development or on less favorable terms to the Company and its stockholders than the Company would otherwise choose in order to obtain upfront license fees needed to fund operations.

The loss of one or more of the Company's significant partners or collaborators could have a material adverse effect on its business, operating results or financial condition. Although the Company is impacted by economic conditions in the biotechnology and pharmaceutical sectors, management does not believe significant credit risk exists as of December 31, 2017.

The Company's significant accounting policies are described in Note 1 to its audited financial statements for the fiscal year ended June 30, 2017, included in its Annual Report on Form 10-K filed with the SEC. There have been no material changes in the Company’s significant accounting policies as previously disclosed in the 2017 Annual Report.

Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers, which requires entities to recognize revenue from the transfer of promised goods or services to customers based on the amount of the consideration to which the entity expects to be entitled to receive in exchange for those goods or services. The new guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations. The purpose of ASU No. 2016-08 is to clarify the implementation of guidance relating to principal versus agent

considerations. For public entities, the amendments in ASU No. 2016-08 are effective for interim and annual reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact of ASU No. 2016-08 on its condensed consolidated financial statements and related disclosures. The FASB subsequently issued ASU No. 2016-10, Revenue from Contracts with Customer (Topic 606) Identifying Performance Obligations and Licensing, to address issues arising from implementation of the new revenue recognition standard. ASU 2014-09 and ASU 2016-10 are effective for interim and annual periods beginning July 1, 2018, and may be adopted earlier, but not before July 1, 2017. The revenue standards are required to be adopted by taking either a full retrospective or a modified retrospective approach. The Company has not elected early adoption and has not concluded on an adoption method. The Company is continuing to assess the impact of the new guidance on its accounting policies and procedures and is evaluating the new requirements as applied to existing revenue contracts. While this assessment is still in progress, the Company believes the most significant impact will relate to the timing of collaboration revenues, where the recognition of variable consideration such as milestone payments may be accelerated. In conjunction with its continuing assessment of the impact of the new guidance, the Company is also evaluating its method of adoption and reviewing and updating its internal controls over financial reporting to ensure that information required to implement the new standard is appropriately captured and recorded. The Company will implement any changes as required to facilitate adoption of the new guidance beginning in the first quarter of fiscal 2019. In addition, the Company continues to monitor additional changes, modifications, clarifications or interpretations undertaken by the FASB or others, which may impact its current conclusions.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU No. 2016-01 requires equity investments to be measured at fair value with changes in fair value recognized in net income; simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; requires separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the condensed consolidated financial statements and clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. ASU No. 2016-01 is effective for financial statements issued for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company is currently evaluating the impact that ASU No. 2016-01 will have on its condensed consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) which supersedes FASB ASC Topic 840, Leases (Topic 840) and provides principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of classification. Leases with a term of twelve months or less will be accounted for similar to existing guidance for operating leases. The standard is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted upon issuance. The Company is currently evaluating the impact that ASU 2016-02 will have on its condensed consolidated financial statements and related disclosures.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (ASU 2016-13). ASU 2016-13 requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. The new standard will be effective for the Company on January 1, 2020. Early adoption will be available on January 1, 2019. The Company is currently evaluating the effect that ASU 2016-13 will have on its condensed consolidated financial statements and related disclosures.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). This amendment will provide guidance on the presentation and classification of specific cash flow items to improve consistency within the statement of cash flows. ASU 2016-15 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. The Company is evaluating the effect that ASU 2016-15 will have on its condensed consolidated financial statements and related disclosures.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) Restricted Cash. The new guidance requires that the reconciliation of the beginning-of-period and end-of-period amounts shown in the statement of cash flows include restricted cash and restricted cash equivalents. If restricted cash is presented separately from cash and cash equivalents on the balance sheet, companies will be required to reconcile the amounts presented on the statement of cash flows to the amounts on the balance sheet. Companies will also need to disclose information about the nature of the restrictions. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The Company does not anticipate ASU 2016-18 will have a material impact on its condensed consolidated financial statements upon adoption.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. The amendments in this ASU clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill, and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company does not anticipate ASU 2017-01 will have a material impact on its condensed consolidated financial statements upon adoption.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. It is effective prospectively for the annual period ending June 30, 2019 and interim periods within that annual period. Early adoption is permitted. The Company does not expect ASU 2017-09 will have a significant impact on its condensed consolidated financial statements upon adoption.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480) and Derivatives and Hedging (Topic 815): I. Accounting for Certain Financial Instruments with Down Round Features; II. Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception. Part I of this update addresses the complexity of accounting for certain financial instruments with down round features. Down round features are features of certain equity-linked instruments (or embedded features) that result in the strike price being reduced on the basis of the pricing of future equity offerings. Current accounting guidance creates cost and complexity for entities that issue financial instruments (such as warrants and convertible instruments) with down round features that require fair value measurement of the entire instrument or conversion option. Part II of this update addresses the difficulty of navigating Topic 480, Distinguishing Liabilities from Equity, because of the existence of extensive pending content in the FASB Accounting Standards Codification. This pending content is the result of the indefinite deferral of accounting requirements about mandatorily redeemable financial instruments of certain nonpublic entities and certain mandatorily redeemable noncontrolling interests. The amendments in Part II of this update do not have an accounting effect. This ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is evaluating the effect that ASU 2017-11 will have on its condensed consolidated financial statements and related disclosures.

Milestone Payments

The Development and Commercialization Agreement with Pierre Fabre contains substantive potential milestone payments of up to $25.0 million for achievement of two regulatory milestones relating to European Commission marketing approvals for two specified indications and of up to $390.0 million for achievement of seven commercialization milestones if certain net sales amounts are achieved for any licensed indications.
 
The License, Development and Commercialization Agreement with Ono Pharmaceutical Co., Ltd. ("Ono") contains substantive potential milestone payments of up to ¥1.8 billion ($16.0 million) for achievement of four development milestones, ¥5 billion ($44.5 million) for the achievement of eight regulatory milestones and ¥10.5 billion ($93.5 million) for the achievement of five commercialization milestones if certain annual net sales targets are achieved. As of December 31, 2017, ¥1.0 billion was the equivalent of approximately $8.9 million (based on the exchange rate published by Oanda).

The Drug Discovery Collaboration Option Agreement with Mirati Therapeutics, Inc. ("Mirati") contains substantive potential milestone payments of up to $18.5 million for eight remaining developmental milestones and up to $674.0 million  for the achievement of fourteen commercialization milestones if certain net sales amounts are achieved in the United States, the European Union and Japan.
 
The Drug Discovery Collaboration Agreement with Loxo Oncology contains substantive potential milestone payments for certain nominated programs of up to $14.0 million for four remaining developmental milestones and up to $625.0 million for the achievement of twenty-two commercialization milestones if certain net sales amounts are achieved for any licensed drug candidates in the United States, the European Union and Japan.

The Collaboration and License Agreement with Asahi Kasei Pharma Corporation ("Asahi Kasei") contains milestone payments of up to $10.0 million related to the achievement of three remaining developmental and regulatory milestones and up to $52.5 million for a milestone payment at the time of the first commercial sale and the achievement of four commercialization milestones if certain net sales amounts are achieved .

The Research Collaboration and License Agreement with Amgen contains substantive potential milestone payments of up to $3.0 million for preclinical development services over a two-year period unless Amgen terminates the Agreement with 60 days' written notice to Array in advance of the contracted payment dates. The Research Collaboration and License Agreement with Amgen contains substantive potential milestone payments of up to $14.0 million for two development milestones and up to $140.0 million for the achievement of four commercialization milestones if certain net sales amounts are achieved for any licensed drug candidates.
 
The Collaboration and License Agreement with AstraZeneca, PLC contains substantive potential milestone payments for selumetinib of up to $36.0 million for nine remaining regulatory milestones and up to $34.0 million for the achievement of three commercialization milestones if certain net sales amounts are achieved in the United States, the European Union and Japan.

On July 28, 2017, AstraZeneca and Merck announced an agreement to share the development and commercialization costs for selumetinib monotherapy and non-PD-L1/PD-1 combination therapy opportunities. Based on this agreement, Array remains eligible to receive from AstraZeneca milestones and royalties on all future selumetinib sales, and now expects to receive a portion of certain consideration paid by Merck to AstraZeneca.  Array has informed AstraZeneca that it is disputing the small consideration that AstraZeneca intends to pay Array related to both upfront and potential future milestones under AstraZeneca's agreement with Merck.  Furthermore, prior to the announcement of the AstraZeneca / Merck agreement, Array informed AstraZeneca of its position that the Neurofibromatosis type 1 (NF1) development program is outside the permitted field of its license. Array filed a legal action on December 7, 2017 naming AstraZeneca as the defendant  in New York State Court in Manhattan regarding this dispute.

Redmile Notes Payable

On September 2, 2016, the Company entered into a Note Purchase Agreement (the “Note Purchase Agreement”) with Redmile Capital Offshore Fund II, Ltd. and Redmile Biopharma Investments I, L.P. (collectively, “Redmile”) pursuant to which the Company issued to Redmile Subordinated Convertible Promissory Notes (the “Notes”) in the aggregate original principal amount of $10.0 million. The Notes bear interest at the rate of 5% per annum and, unless converted or otherwise repaid or satisfied as described below, the principal amount and all accrued interest thereon plus an aggregate exit fee (the “Repayment Amount”) is due and payable on maturity.

On August 7, 2017, the Company entered into an amendment to the Notes issued to Redmile pursuant to which the maturity date of the Notes was extended to August 6, 2018 and the exit fee of the Notes was increased from $3.0 million to an amount equal to 50%, or $5.0 million, of the principal amount under the Notes. If an event of default specified under the Notes occurs, the Note holders may declare the Repayment Amount, and any other amounts payable under the Notes, immediately due and payable. The Company evaluated its debt amendments under ASC 470 and determined that the amendments do not qualify as a troubled debt restructuring or an extinguishment and therefore the effects of the amendments are reflected as a change in fair value.

Conversion of the Notes
 
The Notes contemplate that, solely at the Company’s choice, the Company may elect to form a subsidiary (the “797 Subsidiary”) and contribute certain assets and rights relating to its drug ARRY-797 in exchange for all of the outstanding equity of such 797 Subsidiary. In such event, and if a preferred stock financing of the 797 Subsidiary of at least $10.0 million in aggregate gross proceeds (excluding conversion of the Note) to bona fide institutional investors other than the Note holders (a “Qualified Financing”) closes prior to the Maturity Date, then all outstanding principal and accrued interest under the Notes shall convert automatically into the shares of capital stock issued in the Qualified Financing at a conversion price equal to the lesser of (A) 80% of the purchase price of the securities sold in the Qualified Financing if the closing of the Qualified Financing occurs on or prior to March 1, 2017, or 70% of the purchase price of the securities sold in the Qualified Financing if the closing of the Qualified Financing occurs after March 1, 2017, and (B) the price per share calculated in the same manner as the price per share of equity securities sold in the Qualified Financing, but instead based on a pre-money valuation of the 797 Subsidiary of $75.0 million.

If the Company has not formed the 797 Subsidiary by the Maturity Date or, if a 797 Subsidiary was formed and a Qualified Financing has not closed on or prior to the Maturity Date, then the Company shall have the right to convert, on the Maturity Date, the Repayment Amount into shares of a newly established series of the Company's preferred stock, to be designated as Series A Convertible Preferred Stock, at a conversion price equal to the average daily volume-weighted average price per share of the Company’s common stock during the ten (10) consecutive trading days ending on the trading day immediately preceding the Maturity Date. The shares issued upon any such conversion shall be subject to an aggregate cap equal to 19.99% of the outstanding shares of the Company’s common stock, on an as-converted basis, on the Maturity Date.

Table of Contents

Other Repayment Provisions
 
If, solely at the Company’s choice, prior to the closing of a Qualified Financing or other conversion or repayment or other satisfaction in full of the Notes, the Company sells or transfers substantially all of the assets and rights relating to ARRY-797 to a third party other than the holders of the Notes or any of its affiliates (a “797 Sale”), then upon the closing of such 797 Sale and in full satisfaction of the Notes, the Company is required to pay to the Note holders an amount equal to the greater in the aggregate of (i) $20.0 million or (ii) 15% of the fair market value of the consideration actually paid to the Company or the 797 Subsidiary (or any of their respective affiliates or stockholders) in the 797 Sale, subject to an aggregate $100.0 million cap.

If, solely at the Company’s choice, the Company enters into an agreement with a third party other than the holders of the Notes or any of their affiliates to license ARRY 797 on an exclusive basis for the development and commercialization of ARRY-797 in all fields of use in the United States and any other territories (a “Qualified 797 License”) prior to the closing of a Qualified Financing or other conversion or repayment or other satisfaction in full of the Notes, then upon entering into such Qualified 797 License and in full satisfaction of the Notes, the Company is required to pay to the Note holders an amount in the aggregate equal to 50% of the first $50.0 million in aggregate milestone or royalty payments plus 20% of any subsequent milestone or royalty payments, in each case actually paid to the Company or the 797 Subsidiary (or any of their respective affiliates), as the case may be, pursuant to such Qualified 797 License, subject to an aggregate cap of $100.0 million. In addition, if solely at its choice the Company enters into an exclusive license for the development and commercialization of ARRY-797 to a third party in one or more territories that do not include the United States, the Note holders have the right to elect to treat such license agreement as a “Qualified 797 License” by giving Array written notice of such election with five business days of the effective date of the license agreement.
 
If all or substantially all of the assets of the Company are sold or other change in control of the Company specified in the Notes occurs prior to the closing of a Qualified Financing or other conversion or repayment or other satisfaction in full of the Notes, then upon the closing of such transaction and in full satisfaction of the Notes, at the third party acquirer’s option, the Company is required to either: (i) pay to the Note holders a cash amount in the aggregate equal to $40.0 million; or (ii) (A) pay to the Note holders a cash amount in the aggregate equal to $25.0 million; and (B) grant, or cause to be granted, a right of first refusal to the Note holders to acquire the 797 Subsidiary or the 797 Assets, as the case may be.

Accounting for the Notes

Due to the complexity and number of embedded features within the Notes and as permitted under accounting guidance, the Company elected to account for the Notes and all the embedded features under the fair value option.  The Company recognizes the Notes at fair value rather than at historical cost, with changes in fair value recorded in the statements of operations. Direct costs and fees incurred to issue the Notes were recognized in earnings as incurred and were not deferred. On the initial measurement date of September 2, 2016, the fair value of the Notes was estimated at $10.0 million. On August 7, 2017 when the Notes were amended, the fair value of the Notes was estimated at $12.0 million. Upfront costs and fees related to items for which the fair value option was elected was $0.2 million and was recorded as a component of other expenses for the three months ended September 30, 2016. As of December 31, 2017, the fair value of the Notes was $12.7 million. For more information on the fair value determination of the Notes, see Note 5 - Redmile Notes.

Formation of 797 Subsidiary

The Company formed the 797 Subsidiary,Yarra Therapeutics, LLC, a Delaware limited liability company ("Yarra"), and contributed certain rights and assets related to ARRY-797, including all patents, patent applications and other intellectual property rights, pre-clinical and clinical data, regulatory submissions, inventory, contracts, equipment and books and records related to its ARRY-797 drug program (the “797 Assets”), to Yarra in December 2017. Yarra is currently a wholly-owned subsidiary of Array and Array has appointed a Chief Executive Officer of Yarra who, among other things, will be seeking equity financing for Yarra to fund further development of the 797 Assets. The establishment of Yarra and the Company's contributions described above did not trigger any obligations under the Other Repayment Provisions or the terms associated with the Notes conversion as the Company has not yet sold or licensed any technology to a third party nor has the Company entered into a Qualified Financing.

Silicon Valley Bank Term Loan

On December 22, 2016 the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”) providing for a term loan in the original principal amount of $15.0 million (the “Term Loan Amount”) and a revolving line of credit of up to $5.0 million (“Revolving Line”). The Company may request advances under the revolving line of credit, which may be repaid and reborrowed, or utilize the line of credit for the issuance of letters of credit, foreign exchange contracts or other cash management services. The Company utilized $14.6 million of the proceeds from the term loan to repay in full its outstanding obligations under the Loan and Security Agreement dated June 28, 2005, as amended, with Comerica Bank. The entire Term Loan Amount was loaned on the Effective Date, and the Company has obtained a letters of credit in the aggregate amount of $2.9 million to secure the Company's obligations under its lease agreement for its Boulder, Colorado and Cambridge, Massachusetts facilities. The cost of the term loan approximated its fair value.
The outstanding principal amount under the term loan bears interest at a floating per annum rate equal to the Prime Rate minus 2.0% (but not less than 0.0%) and the principal amount of any advances outstanding under the revolving line bear interest at a floating per annum rate equal to the prime rate. The interest rate was 2.50% as of December 31, 2017. The Company must make monthly payments of interest under the term loan commencing January 1, 2017 until maturity and, commencing on January 1, 2019 and monthly thereafter, the Company must also make payments of principal under the term loan based on a 36-month amortization schedule. Payments of accrued interest on any advances outstanding under the revolving line of credit are payable monthly. A final payment of accrued interest and principal due on the term loan and on any outstanding advances is due on the maturity date of December 1, 2021.
The Loan Agreement provides for a revolving line commitment fee of $50 thousand, payable in five equal installments from the Effective Date and an unusued revolving line facility fee equal to 0.2% per annum of the average unused portion of the Revolving Line. Upon repayment or acceleration of the term loan, a final payment fee equal to 8.0% of the Term Loan Amount is payable. The final payment fee of $1.2 million is being recognized on a straight line basis over the term of the loan and is being reflected as debt discount. If the term loan is prepaid or accelerated prior to the maturity date, the Company must also pay a fee equal to (i) 2.0% of the Term Loan Amount if such prepayment or acceleration occurs on or prior to the first anniversary of the Effective Date, or (ii) 1.0% of the Term Loan Amount if such prepayment or acceleration occurs after the first anniversary of the Effective Date. If the revolving line is terminated prior to the maturity date for any reason, the Company must pay a termination fee equal to (i) 2.0% of the Revolving Line if such termination occurs on or prior to the first anniversary of the Effective Date, or (ii) 1.0% of the Revolving Line if such termination occurs after the first anniversary of the Effective Date.
The Company granted SVB a first priority security interest in all assets other than its intellectual property, provided that accounts and proceeds of the Company’s intellectual property constitutes collateral and the Company has agreed not to encumber its intellectual property without SVB’s consent. The Loan Agreement contains customary covenants, including restrictions on changes in control of the Company, the incurrance of additional indebtedness, future encumbrances on Array’s assets, the payment of dividends or distributions on the Company’s common stock and the sale, lease, transfer or disposition of Binimetinib and Encorafenib outside of certain markets if the Company’s cash and cash equivalents maintained with SVB fall below certain levels. In addition, the Company must maintain a liquidity ratio, defined as (i) the Company’s unrestricted cash and cash equivalents maintained at SVB or its affiliates plus eligible accounts divided by (ii) all outstanding obligations owed to SVB, of at least 2.0 to 1.0, measured monthly.

Upon an event of default under the Loan Agreement, SVB is entitled to accelerate and demand payment of all amounts outstanding under the Loan Agreement, including payment of all applicable termination and prepayment fees, demand that the Company deposit at least 105% of the face amount of any letters of credit remaining undrawn to secure all obligations thereunder, and exercise other remedies available to SVB under the Loan Agreement and at law or in equity.
3.00% Convertible Senior Notes Due 2020
 
On June 10, 2013, through a registered underwritten public offering, the Company issued and sold $132.3 million aggregate principal amount of 3.00% convertible senior notes due 2020 (the "2020 Notes"), resulting in net proceeds to Array of approximately $128.0 million after deducting the underwriting discount and offering expenses. As described below, in December 2017, the Company completed an exchange with certain holders of the 2020 Notes of $126.1 million in principal of the 2020 Notes for an equal principal amount of newly issued 2.625% convertible senior notes due 2024 and for shares of the Company's common stock. The holders of the remaining 2020 Notes elected to convert all remaining outstanding 2020 Notes into shares of the Company's common stock in December 2017.

The 2020 Notes were the general senior unsecured obligations of Array. The 2020 Notes bore interest at a rate of 3.00% per year, payable semi-annually on June 1 and December 1 of each year with all principal due at maturity. The 2020 Notes were scheduled to mature on June 1, 2020, unless earlier converted by the holders or redeemed by the Company.

Exchange and Conversion of 2020 Notes

On November 16 and November 20, 2017, the Company entered into separate, privately negotiated exchange agreements (“Exchange Agreements”) with a limited number of holders (“Noteholders”) of its outstanding 2020 Notes, pursuant to which the Company agreed to exchange (the “Exchanges”) approximately $126.1 million in aggregate principal amount of 2020 Notes held by the Noteholders for (i) an aggregate of 7,955,560 shares of its Common Stock (collectively, the “Exchange Shares”), and (ii) an aggregate of $126.1 million in aggregate principal amount of its newly issued 2.625% Convertible Senior Notes due 2024 (the “2024 Notes”).

Upon completion of the Exchanges on December 1, 2017, the aggregate principal amount of the 2020 Notes was reduced to approximately $6.2 million. On December 4, 2017, the Company issued a notice of redemption to the remaining holders of the remaining 2020 Notes, pursuant to which the Company would redeem the outstanding 2020 Notes for cash unless the holders of such 2020 Notes notified the Company of their intention to convert their 2020 Notes into shares of the Company's common stock based on the conversion rate then in effect. As of December 31, 2017, holders of the remaining 2020 Notes had converted such 2020 Notes into an aggregate of 913,368 shares of the Company's common stock. The Company accounted for the exchange of the 2020 Notes for the 2024 Notes and conversion of the 2020 Notes as debt extinguishments in accordance with ASC 470 and as a result recorded a $6.5 million loss on extinguishment for the three months ended December 31, 2017.

2.625% Convertible Senior Notes Due 2024
 
The 2024 Notes issued on December 1, 2017 in the Exchanges are the Company’s direct unsecured obligations and rank equal in right of payment with all of the Company’s other existing and future unsecured and unsubordinated indebtedness, including the Redmile Notes.  The 2024 Notes are effectively subordinated to any of the Company’s existing and future secured indebtedness, including the Company’s indebtedness under its loan and security agreement with Silicon Valley Bank, to the extent of the value of the Company’s assets that secure such indebtedness. 
 
The 2024 Notes will mature on December 1, 2024 and bear interest at a rate of 2.625%, payable semiannually in arrears on June 1 and December 1 of each year, beginning on June 1, 2018.
 
Prior to September 1, 2024, holders may convert the 2024 Notes only under the following circumstances: (1) during any fiscal quarter commencing after December 31, 2017, if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five consecutive business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2024 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the common stock and the applicable conversion rate on each such trading day; (3) if the

Company calls the 2024 Notes for redemption, at any time prior to the close of business on the business day prior to the redemption date; or (4) upon the occurrence of certain corporate events specified in the Indenture dated December 1, 2017 (the "Indenture") with The Bank of New York Mellon Trust Company, N.A., trustee of the 2024 Notes (the "Trustee"). On or after September 1, 2024 until the close of business on the scheduled trading day immediately prior to the maturity date, holders may convert their 2024 Notes at any time, regardless of the foregoing circumstances. Upon conversion, the holders will receive, at the Company’s option, shares of the Company’s common stock, cash or a combination of shares and cash. The 2024 Notes will be convertible at an initial conversion rate of 64.6987 shares per $1,000 in principal amount of 2024 Notes, equivalent to a conversion price of approximately $15.46 per share, subject to certain adjustments set forth in the Indenture.
 
Upon the occurrence of a fundamental change (as defined in the Indenture) involving Array, holders of the 2024 Notes may require Array to repurchase all or a portion of their Notes for cash at a price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

On or after December 8, 2021 and prior to September 1, 2024, the Company may redeem for cash all or part of the outstanding 2024 Notes if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including at least one of the five trading days immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption.  The redemption price will equal 100% of the principal amount of the 2024 Notes to be redeemed, plus all accrued and unpaid interest to, but excluding, the redemption date.
 
The Indenture contains customary terms and covenants and events of default. If an event of default (as defined in the Indenture) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in aggregate principal amount of the 2024 Notes then outstanding by notice to the Company and the Trustee, may, and the Trustee at the request of such holders shall, declare 100% of the principal of, premium, if any, and accrued and unpaid interest on all the Notes to be due and payable. In the case of an event of default arising out of certain bankruptcy or insolvency events (as set forth in the Indenture), 100% of the principal of, premium, if any, and accrued and unpaid interest on the 2024 Notes will automatically become due and payable. Notwithstanding the foregoing, if Array fails to comply with certain reporting covenants under the Indenture, the Company may elect to pay additional interest on the Notes as the sole remedy for such a default.
 
The Indenture provides that the Company shall not amalgamate or consolidate with or merge with or into another person, or convey, transfer or lease its properties and assets substantially as an entirety to another person, unless (a) the successor person, if any, is a corporation organized and existing under the laws of the United States, any state of the United States or the District of Columbia and expressly assumes by supplemental indenture all of the Company’s obligations under the 2024 Notes and the Indenture; (b) immediately after giving effect to the transaction, no default or event of default shall have occurred and be continuing; (c) the Company shall have undertaken commercially reasonable efforts to restructure the 2024 Notes so that, after any such transaction is given effect, any conversion of the 2024 Notes would be exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 3(a)(9) thereof; (d) the Company shall have delivered to the Trustee an officers’ certificate and an opinion of counsel, each stating that such transaction and such supplemental indenture (if any) comply with the Indenture; and (e) other conditions specified in the Indenture are met.

In accordance with ASC 470-20, the Company used an effective interest rate of 9.75% to determine the liability component of the 2024 Notes. This resulted in the recognition of $80.4 million as the liability component of the 2024 Notes and the recognition of the residual $45.7 million as the debt discount with a corresponding increase to additional paid-in capital for the equity component of the 2024 Notes. The underwriting discount and estimated offering expenses of $4.3 million were allocated between the debt and equity issuance costs in proportion to the allocation of the liability and equity components of the 2024 Notes. Equity issuance costs of $1.6 million were recorded as an offset to additional paid-in capital. Total debt issuance costs of $2.7 million were recorded on the issuance date, and are reflected in the Company's balance sheets for all periods presented on a consistent basis with the debt discount, or as a direct deduction from the carrying value of the associated debt liability. The debt discount and debt issuance costs will be amortized as non-cash interest expense through December 1, 2024. The balance of unamortized debt issuance costs was $2.7 million as of December 31, 2017.

The fair value of the 2024 Notes was approximately $144.4 million at December 31, 2017 and was determined using Level 2 inputs based on their quoted market values.

Redmile Notes

To measure the fair value of the principal amount on the Notes issued to Redmile, the Company was required to determine the fair value of the principal amount on the Notes and the conversion feature of the Notes. The Company utilized a Monte Carlo simulation to determine the method of payment of the principal amount by potential outcome and scenario, and applied the income approach to determine the fair value of the Notes, discounting the principal amount due under the Notes by market interest rates under potential scenarios. The Monte Carlo simulation utilized the following assumptions: (i) expected term; (ii) common stock price; (iii) risk-free interest rate; and (iv) expected volatility. The assumptions the Company used in the simulation were based on factors the Company believed that participants would use in pricing the liability components, including market interest rates, credit standing, yield curves, volatilities, and risk-free rates, all of which are defined as Level 3 observable inputs.

To measure the fair value of the conversion feature of the Notes issued to Redmile, the Company performed an analysis to estimate the pre-money value of the 797 Subsidiary. The Company then applied the pre-money value of the 797 Subsidiary to the conversion scenarios under the Notes to determine the fair value of the conversion feature.

The Company incorporated the estimated volatilities and the risk-free rates on the principal amount of the Notes into the Monte Carlo simulation under each potential scenario and weighted volatility and rates based on the probability of each scenario occurring. Subsequently, the estimated implied interest rates were applied to the principal amount of these Notes under potential scenarios and were weighted based on the probability of each scenario occurring. 

The fair value of the Notes was impacted by certain unobservable inputs, most significantly management's assumptions regarding the discount rates used, the probabilities of certain scenarios occurring, expected volatility, share price performance, and expected scenario timing. Significant changes to these inputs in isolation or in the aggregate could result in a significantly different fair value measurement.

NOTE 6 – STOCKHOLDERS’ EQUITY

Common Stock Offering

On September 19, 2017, the Company closed an underwritten public offering of 24.1 million shares of its common stock, which included 3.1 million shares of common stock issued upon the exercise in full of the option to purchase additional shares granted to the underwriters in the offering. The shares were sold to the public at an offering price of $10.75 per share. The total net proceeds from the offering were $243.0 million, after underwriting discounts and commissions and offering expenses of approximately $15.7 million.  The Company intends to use the net proceeds from this offering to fund research and development efforts, including clinical trials for its proprietary candidates, build and scale its commercial capabilities, and for general working capital and corporate purposes.

At-the-Market Equity Offering

The Company entered into a Sales Agreement with Cantor Fitzgerald & Co. ("Cantor") dated March 27, 2013, which was subsequently amended to permit the sale by Cantor, acting as its sales agent, of up to $75.0 million in additional shares of the Company's common stock from time to time in an at-the-market offering under the Sales Agreement. All sales of shares have been and will continue to be made pursuant to an effective shelf registration statement on Form S-3 filed with the SEC. The Company pays Cantor a commission of approximately 2% of the aggregate gross proceeds the Company receives from all sales of the Company's common stock under the Sales Agreement. The amended Sales Agreement continues indefinitely until either party terminates the Sales Agreement, which may be done on 10 days prior written notice. The Company received net proceeds on sales under the Sales Agreement of approximately $2.8 million at a weighted average price of $9.02 during the six months ended December 31, 2017.

NOTE 7 – SHARE-BASED COMPENSATION

Share-based compensation expense for all equity awards issued pursuant to the Array BioPharma Amended and Restated Stock Option and Incentive Plan (the "Option and Incentive Plan") and for estimated shares to be issued under the Employee Stock Purchase Plan ("ESPP") for the current purchase period was approximately $3.2 million and $2.1 million for the three months ended December 31, 2017 and 2016, respectively, and $8.8 million and $4.0 million for the six months ended December 31, 2017 and 2016, respectively, including a $2.5 million charge in the first quarter of fiscal 2018 for accelerated vesting of stock options and RSUs to a departing executive.

The Company uses the Black-Scholes option pricing model to estimate the fair value of its share-based awards. In applying this model, the Company uses the following assumptions:

Risk-free interest rate - The Company determines the risk-free interest rate by using a weighted average assumption equivalent to the expected term based on the U.S. Treasury constant maturity rate.
Expected term - The Company estimates the expected term of its options based upon historical exercises and post-vesting termination behavior.
Expected volatility - The Company estimates expected volatility using daily historical trading data of its common stock.
Dividend yield - The Company has never paid dividends and currently have no plans to do so; therefore, no dividend yield is applied.

The aggregate intrinsic value in the above table is calculated as the difference between the closing price of the Company's common stock at December 31, 2017, of $12.80 per share and the exercise price of the stock options that had strike prices below the closing price. The total intrinsic value of all options exercised was $14.8 million during the six months ended December 31, 2017. The total intrinsic value of all options exercised during the six months ended December 31, 2016 was $0.6 million.

As of December 31, 2017, there was approximately $32.8 million of total unrecognized compensation expense related to the unvested stock options shown in the table above, which is expected to be recognized over a weighted average period of 3.1 years.

Restricted Stock Units ("RSUs")

The Option and Incentive Plan provides for the issuance of RSUs that each represent the right to receive one share of Array common stock, cash or a combination of cash and stock, typically following achievement of time- or performance-based vesting conditions. The Company's RSU grants that vest subject to continued service over a defined period of time, will typically vest between two to four years, with a percentage vesting on each anniversary date of the grant, or they may be vested in full on the date of grant. Vested RSUs will be settled in shares of common stock upon the vesting date, upon a predetermined delivery date, upon a change in control of Array, or upon the employee leaving Array. All outstanding RSUs may only be settled through the issuance of common stock to recipients, and the Company intends to continue to grant RSUs that may only be settled in stock. RSUs are assigned the value of Array common stock at date of grant, and the grant date fair value is amortized over the applicable vesting period.

As of December 31, 2017, there was $8.2 million of total unrecognized compensation cost related to unvested RSUs granted under the Option and Incentive Plan. The cost is expected to be recognized over a weighted-average period of approximately 3.4 years. The fair market value on the grant date for RSUs that vested during the six months ended December 31, 2017 and 2016 was $1.8 million and $0.5 million, respectively.

Employee Stock Purchase Plan

The ESPP allows qualified employees (as defined in the ESPP) to purchase shares of the Company's common stock at a price equal to 85% of the lower of (i) the closing price at the beginning of the offering period or (ii) the closing price at the end of the offering period. Effective each January 1, a new 12-month offering period begins that will end on December 31 of that year. However, if the closing stock price on July 1 is lower than the closing stock price on the preceding January 1, then the original 12-month offering period terminates, and the purchase rights under the original offering period roll forward into a new six-month offering period that begins July 1 and ends on December 31. As of December 31, 2017, the Company had 0.9 million shares available for issuance under the ESPP. The Company issued 154 thousand and 282 thousand shares under the ESPP during fiscal 2017 and 2016, respectively.

NOTE 8 - RELATED PARTY TRANSACTIONS

The Company is party to a Drug Discovery Collaboration Option Agreement with Mirati pursuant to which the Company is providing certain drug discovery and research activities to Mirati in which the Company has received upfront payments, license fees and reimbursement for research and development services and under which the Company is entitled to receive milestone payments based on achievement of certain milestones, as described in Note 3 - Collaboration and Other Agreements. Dr. Charles Baum, a current member of Array’s Board of Directors, is the President and Chief Executive Officer of Mirati.

As described above in Note 4 - Debt - Notes Payable, the Company entered into a Note Purchase Agreement with Redmile and issued Notes to Redmile on September 2, 2016. At that time, affiliates of Redmile held more than 10% of the Company's common stock. As of September 30, 2017, Redmile and its affiliates hold less than 10% of the Company's common stock.

NOTE 9 - NET LOSS PER SHARE

Basic and diluted loss per common share are computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted loss per share includes the determinants of basic net income per share and, in addition, gives effect to the potential dilution that would occur if securities or other contracts to issue common stock were exercised, vested or converted into common stock, unless they are anti-dilutive. Diluted weighted average common shares include common stock potentially issuable under our convertible notes, notes payable at fair value, vested and unvested stock options and unvested RSUs, except where the effect of including them is anti-dilutive.

Encorafenib and Binimetinib

In March 2015, Array regained development and commercialization rights to binimetinib, a MEK inhibitor, under the Termination and Asset Transfer Agreement with Novartis Pharma AG and Novartis Pharmaceutical Ltd. and to encorafenib, a BRAF inhibitor, under the Asset Transfer Agreement with Novartis Pharma AG (collectively, the “Novartis Agreements”). Along with global ownership of both assets, Array received an upfront payment of $85.0 million from Novartis. We believe these programs present significant opportunity to Array in the area of oncology.

We have also entered into agreements with Pierre Fabre Medicament SAS, (“Pierre Fabre” or "PFM") and Ono Pharmaceutical Co., Ltd. ("Ono") related to the encorafenib and binimetinib programs. The Development and Commercialization Agreement, which became effective in December 2015 (the "PF Agreement"), granted Pierre Fabre rights to commercialize encorafenib and binimetinib in all countries except for the United States, Canada, Japan, Korea and Israel, including Europe (referred to as the "PF Territory"). The License, Development and Commercialization Agreement with Ono, which became effective in May 2017 (the "Ono Agreement"), granted Ono exclusive rights to commercialize encorafenib and binimetinib in Japan and the Republic of Korea (referred to as

27

Table of Contents

the "Ono Territory"), along with the right to develop these products in the Ono Territory. Array retains all rights outside the Ono Territory and the PF Territory.

All clinical trials involving encorafenib and binimetinib that were active or planned when the Novartis Agreements became effective in March 2015, including the COLUMBUS trial and other then active Novartis sponsored and investigator sponsored clinical studies, continue to be reimbursed pursuant to the terms of the Novartis Agreements. Further worldwide development activities of encorafenib and binimetinib are governed by a Global Development Plan ("GDP") with Pierre Fabre. Pierre Fabre and Array will jointly fund worldwide development costs under the GDP, with Array covering 60% and Pierre Fabre covering 40% of such costs. The initial GDP includes multiple trials, including the BEACON CRC trial, and Pierre Fabre and Array have agreed to commit at least €100 million in combined funds for these studies in colorectal cancer ("CRC") and melanoma.

Pierre Fabre is responsible for seeking regulatory and pricing and reimbursement approvals in the European Economic Area and its other licensed territories. We have also entered into a Clinical Supply Agreement with Pierre Fabra and have agreed to enter into a commercial supply agreement with Pierre Fabre pursuant to which we will supply or procure the supply of clinical and commercial supplies of drug substance and drug product for Pierre Fabre, the costs of which will be borne by Pierre Fabre. We have also agreed to cooperate with Pierre Fabre to ensure the supply of companion diagnostics for use with binimetinib and encorafenib in indications where needed.

Encorafenib and binimetinib are currently being studied in Phase 3 trials in advanced cancer patients, including the COLUMBUS trial studying encorafenib in combination with binimetinib in patients with BRAF-mutant melanoma and the BEACON CRC trial to study encorafenib in combination with binimetinib and cetuximab, an EGFR antibody, in patients with BRAFV600E-mutant CRC ("BRAFm CRC"). Encorafenib and binimetinib are investigational medicines and are not currently approved in any country.

Novartis continues to substantially fund all ongoing trials with encorafenib and binimetinib that were active or planned as of the close of the Novartis Agreements in 2015, including the COLUMBUS Phase 3 trial. Reimbursement revenue from Novartis was approximately $88.5 million for the 12 months ended December 31, 2017, of which $22.4 million was recorded in the quarter ended December 31, 2017. Total revenue and upfront collected from Novartis since the start of the 2015 agreement is $348.7 million.

COLUMBUS PHASE 3 TRIAL
In February 2018, we announced overall survival results from the COLUMBUS trial which showed median OS of 33.6 months for patients taking encorafenib (BRAF inhibitor, 450 mg once daily) in combination with binimetinib (MEK inhibitor, 45 mg twice daily) compared to 16.9 months for patients treated with vemurafenib as a monotherapy. As previously announced, the combination of encorafenib and binimetinib was generally well-tolerated. Grade 3/4 adverse events (AEs) that occurred in more than 5% of patients receiving the combination were increased gamma-glutamyltransferase (GGT) (9%), increased blood creatine phosphokinase (CK) (7%) and hypertension (6%). The incidence of selected any grade AEs of special interest, defined based on toxicities commonly associated with commercially available BRAF+MEK-inhibitor treatments for patients receiving the combination of encorafenib and binimetinib included: rash (23%), pyrexia (18%), retinal pigment epithelial detachment (13%) and photosensitivity (5%). Full safety results of COLUMBUS Part 1 were presented at the 2016 Society for Melanoma Research Annual Congress.

In September 2017, the FDA accepted for review the two NDAs we submitted to support use of the combination of encorafenib 450 mg once daily and binimetinib 45 mg twice daily (COMBO450) for the treatment of patients with BRAF-mutant advanced, unresectable or metastatic melanoma. The FDA set a target action date under the Prescription Drug User Fee Act (PDUFA) of June 30, 2018 for both applications. In addition, the FDA informed us that, based on its preliminary review of the applications, it has not identified any potential review issues, and that it is not currently planning to hold an advisory committee meeting to discuss these NDAs. We completed our NDA submissions based on findings from the pivotal Phase 3 COLUMBUS trial.

Metastatic melanoma is the most serious and life-threatening type of skin cancer and is associated with low survival rates. There are about 200,000 new cases of melanoma diagnosed worldwide each year, approximately half of which have BRAF mutations, a key target in the treatment of metastatic melanoma.

BEACON CRC PHASE 3 TRIAL
We continue to enroll BEACON CRC, a global Phase 3 trial of encorafenib and cetuximab, with or without binimetinib, versus standard of care in patients with BRAF-mutant CRC who have previously received one or two prior regimens.

28

Table of Contents

BRAF mutations are estimated to occur in 10% to 15% of patients with CRC and represent a poor prognosis for these patients.

At the ASCO 2018 Gastrointestinal Cancers Symposium, updated results from the 30 patient safety lead-in of the Phase 3 BEACON CRC trial evaluating the triplet combination of encorafenib, binimetinib and cetuximab in patients with BRAF-mutant metastatic CRC whose disease has progressed after one or two prior regimens were presented. The estimated median progression-free survival (mPFS) at the time of analysis was 8 months in 29 patients with BRAFV600E-mutant CRC. The confirmed overall response rate ("ORR") was 48% with 3 complete responses in patients with BRAFV600E-mutant CRC. Further, the ORR was 62% in the 16 patients who received only one prior line of therapy. These data represent improvements compared to several separate historical published standard of care benchmarks for this population which range between 4% to 8% ORR and 1.8 and 2.5 months mPFS. The triplet combination was generally well-tolerated. Two patients discontinued treatment due to adverse events (AEs) with only one of these considered related to treatment. The most common grade 3 or 4 AEs seen in at least 10% of patients were fatigue, urinary tract infection, increased aspartate aminotransferase (AST) and increased blood CK.

BEACON CRC is the first and only Phase 3 trial designed to test a BRAF/MEK combo targeted therapy in BRAF-mutant advanced CRC. The trial was initiated based on results from a Phase 2 trial that were presented at the 2016 ASCO annual meeting. In the doublet arm of encorafenib and cetuximab, mOS exceeded one year, which is more than double several separate historical published standard of care benchmarks for this population. Further, the ORR was 22% and the mPFS was 4.2 months. Historical published ORR and mPFS benchmarks in this patient population using standard of care regimens range between 4% to 8% and 1.8 and 2.5 months, respectively.

Worldwide, CRC is the third most common type of cancer in men and the second most common in women, with approximately 1.4 million new diagnoses in 2012. Of these, nearly 750,000 were diagnosed in men, and 614,000 in women. Globally in 2012, approximately 694,000 deaths were attributed to CRC. In the U.S. alone, an estimated 140,250 patients will be diagnosed with cancer of the colon or rectum in 2018, and approximately 50,000 are estimated to die of their disease. In the U.S., BRAF mutations are estimated to occur in 10% to 15% of patients with CRC and represent a poor prognosis for these patients. Based on recent prospective historical data, the prevalence of MSI-H in tumors from patients with metastatic BRAF-mutant CRC ranged from 14% in a recent Phase 1b/2 trial (NCT01719380) (Array, data on file) to 18% in a recent Southwestern Oncology Group (SWOG) randomized Phase 2 trial.

IMMUNO-ONCOLOGY COLLABORATIONS WITH BRISTOL-MYERS SQUIBB, MERCK AND PFIZER
Array is developing binimetinib in combination with PD-1 / PD-L1 checkpoint inhibitors. We have announced separate, strategic collaborations with Bristol-Myers Squibb, Merck and Pfizer, but in each case, are pursuing a unique trial design to explore different clinical approaches.
  
Bristol-Myers Squibb
The clinical trial with Bristol-Myers Squibb continues to advance and is designed to investigate the safety, tolerability and efficacy of binimetinib in combination with nivolumab (anti-PD-1 therapy), with and without ipilimumab (CTLA-4 antibody), in patients with advanced metastatic microsatellite stable (MSS) CRC and the presence of a RAS mutation who have received one or two prior regimens. The trial is jointly supported by Array and Bristol-Myers Squibb and sponsored by Array.

Merck
The clinical trial with Merck is designed to investigate the safety, tolerability and efficacy of binimetinib in combination with pembrolizumab (anti-PD-1 therapy), with and without FOLFOX or FOLFIRI (chemotherapy) in patients with CRC whose tumors are not microsatellite instability-high (MSI-H). After establishing combinability in separate Phase 1 cohorts, the trial will enroll expansion cohorts of 1st and 2nd-line CRC patients onto these novel triplet combinations to determine effectiveness. The trial will be sponsored and funded by Merck, with Array providing binimetinib supply.

Pfizer
The clinical trial with Pfizer is designed to investigate the safety, tolerability and efficacy of several novel anti-cancer combinations, including binimetinib, avelumab (anti-PD-L1 therapy) and talazoparib (PARP inhibitor) across various tumor types. The multi-arm Phase 1b clinical trial is designed to establish recommended doses of different regimens combining the drugs. Initially, the focus will be in non-small cell lung cancer (NSCLC) and pancreatic cancer, with additional indications being explored at a later stage. The study is expected to begin by the third quarter of 2018, and results will be used to determine optimal approaches to further clinical development of these combinations. The trial will be sponsored and funded by Pfizer, with Array providing binimetinib supply.

ARRY-382 and ARRY-797 PROGRAMS
ARRY-382
ARRY-382 is a wholly-owned, highly selective and potent, small molecule inhibitor of CSF-1R kinase activity. We are advancing a Phase 1/2 trial of ARRY-382 in combination with pembrolizumab, an anti-PD-1 therapy, in patients with advanced solid tumors. Data from the Phase 1b dose escalation trial were presented at the 2017 Society for Immunotherapy of Cancer (SITC) Annual Meeting.  In the trial, the recommended Phase 2 dose of ARRY-382 was determined to be 300 mg daily in combination with pembrolizumab 2 mg/kg given intravenously every 3 weeks. Nineteen patients, with a median of two prior lines of therapy and 42% with ≥3 prior regimens, were treated in the study.  Patients with pancreatic (n=6), colorectal (n=5), ovarian (n=3), gastric and melanoma (n=2, each), and triple negative breast cancer (n=1) were enrolled.  Investigators noted that ARRY-382 had a manageable safety profile when administered with pembrolizumab in this trial, and the most common grade 3/4 AEs (>10%), regardless of causality, included increased AST, increased blood CK, rash, increased lipase, increased alkaline phosphatase (ALP), increased alanine aminotransferase (ALT) and anemia. The combination of ARRY-382 and pembrolizumab demonstrated early signs of activity, with 11% (n=2) of patients achieving a confirmed partial response, based on RECIST version 1.1 guidelines  The first responder, who was treated with ARRY-382 at 200 mg, had Stage III pancreatic ductal adenocarcinoma.  As of the data cut-off, this patient was on study treatment in cycle 14 (42 weeks).  The second responder, who was treated with ARRY-382 at 300 mg, had stage IV ovarian cancer with liver metastasis.  As of the data cut-off, this patient was on study treatment in cycle 8 (24 weeks). These early signs of activity in patients with tumor types that have been historically unresponsive to anti-PD1 therapies are encouraging.

ARRY-797
In December 2017, we contributed certain rights and assets relating to ARRY-797, an oral, selective p38 MAPK inhibitor, to Yarra Therapeutics, LLC, a newly-formed, wholly-owned subsidiary of Array ("Yarra"). See Note 4 - Debt - Redmile Notes Payable - Formation of 797 Subsidiary. Array has appointed a Chief Executive Officer of Yarra and, as part of his duties, he will seek equity financing for Yarra to fund further development of ARRY-797, including a Phase 3 trial as well as for general working capital purposes. If Yarra is unable to obtain sufficient funding, the rights to ARRY-797 will revert to Array.

Business Development and Partner Concentrations
 
We currently license or partner certain of our compounds and/or programs and enter into collaborations directly with pharmaceutical and biotechnology companies through opportunities identified by our business development group, senior management, scientists and customer referrals. In general, our partners may terminate their agreements with us with 60 to 180 days' prior notice. Specifics regarding termination provisions under our material collaboration or partnering agreements can be found in Note 5 – Collaboration and License Agreements to our audited financial statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017.

Additional information related to the concentration of revenue among our partners is reported in Note 1 – Overview, Basis of Presentation and Summary of Significant Accounting Policies – Concentration of Business Risks to our unaudited condensed financial statements included elsewhere in this Quarterly Report on Form 10-Q.

All of our collaboration and license agreements are denominated in U.S. dollars, except our agreement with Ono, which is denominated in Japanese Yen.

Critical Accounting Policies and Estimates
 
Management's discussion and analysis of our financial condition and results of operations are based upon our accompanying unaudited condensed financial statements, which have been prepared in conformity with U.S. generally accepted accounting principles, or U.S. GAAP, and which requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent

Table of Contents

assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. These estimates are the basis for our judgments about the carrying values of assets and liabilities, which in turn may impact our reported revenue and expenses. Our actual results could differ significantly from these estimates under different assumptions or conditions.

An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimate that are reasonably likely to occur periodically, could materially impact the condensed consolidated financial statements. There have been no significant changes to our critical accounting policies since the beginning of this fiscal year. Our critical accounting policies are described under the heading "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017.

On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJA”) was signed into law, which among other changes reduces the federal corporate tax rate to 21%. We have conducted a preliminary review of the impact of the TCJA and do not anticipate it to have a material impact on the our consolidated condensed financial statements primarily due to the valuation allowance recorded against our net deferred tax assets.

Reimbursement revenue consists of amounts received for reimbursement of costs we incur from our license partners where Array acts as a principal, controls the research and development activities, bears credit risk and may perform part of the services required in the transactions.

In connection with regaining all development and commercialization rights to binimetinib and obtaining all development and commercialization rights to encorafenib from Novartis on March 2, 2015, we entered into two Transition Agreements with Novartis, one associated with the binimetinib Termination and Asset Transfer Agreement and the other associated with the encorafenib Asset Transfer Agreement. Under the Transition Agreements, Novartis provides us with substantial financial support for all transitioned clinical trials involving binimetinib and encorafenib in the form of reimbursement to Array for all associated out-of-pocket costs and for one-half of our fully-burdened FTE costs based on an agreed FTE rate. Novartis transitioned responsibility for Novartis-conducted trials at designated points for each trial and is providing continuing financial support to us for completing the trials. Substantially all reimbursement revenue consists of reimbursements from Novartis under the Transition Agreements for specific clinical trials involving binimetinib and encorafenib.

As shown in the table above, we recognized approximately $22.4 million and $27.9 million in reimbursement revenue for the three months ended December 31, 2017 and 2016, respectively, and we recognized approximately $40.6 million and $59.3 million in reimbursement revenue for the six months ended December 31, 2017 and 2016, respectively. The decrease in reimbursement revenue for the three and six months ended December 31, 2017

compared with the prior year is attributable to the advancement of the transitioned studies which have begun to wind down, resulting in lower reimbursable expenses.

Collaboration and Other Revenue
 
Collaboration and other revenue consists of revenue for our performance of drug discovery and development activities in collaboration with partners, which includes development of proprietary drug candidates we out-license, as well as screening, lead generation, and lead optimization research.

Collaboration and other revenue increased during the periods presented above, with approximately $8.5 million and $6.0 million for the three months ended December 31, 2017 and 2016, respectively, and approximately $16.5 million and $12.3 million for the six months ended December 31, 2017 and 2016, respectively. The increase mainly resulted from our collaboration with Pierre Fabre, including the advancement of the BEACON clinical trial, which resulted in higher collaboration revenue. Also contributing to the increase were new and expanded collaborations with Amgen, Loxo and Mirati.

License and Milestone Revenue

License and milestone revenue consists of upfront license fees and ongoing milestone payments from partners and collaborators.

License and milestone revenue was $11.3 million and $10.5 million for the three months ended December 31, 2017 and 2016, respectively, and $14.9 million and $12.2 million for the six months ended December 31, 2017 and 2016, respectively.

The increases in license and milestone revenue were attributable to the acceleration of $7.9 million previously deferred revenue from the upfront payment received from Asahi Kasai in fiscal 2016 offset by two milestone payments that were earned in the second quarter of fiscal 2017. During the current quarter, we were notified by Asahi Kasai that our development obligations were substantially complete, which caused us to accelerate the remaining deferred license revenue. Prior to Asahi Kasai's notice, we were obligated to perform research and development services on potential additional compounds at Asahi Kasai's discretion. Largely offsetting this increase, we earned and recognized a $6.0 million milestone from Loxo for the advancement of LOXO-101, a PanTrk inhibitor for cancer, and as well as a $2.5M million milestone from Roche for the advancement of danoprevir, the NS3/4A protease inhibitor for Hepatitis C, during the quarter ended December 31, 2016.

Cost of Partnered Programs

Cost of partnered programs represents research and development costs attributable to discovery and development including preclinical and clinical trials we may conduct for or with our partners. Research and development costs primarily consist of personnel related expenses, including salaries, benefits, and other related expenses, stock-based compensation, payments made to third party contract research organizations for preclinical and clinical studies, investigative sites for clinical trials and consultants, the cost of acquiring and manufacturing clinical trial materials, costs associated with regulatory filings and patents, software and facilities, and laboratory costs and other supply costs.

Cost of partnered programs increased from approximately $9.0 million to $13.7 million during the three months ended December 31, 2016 and 2017, respectively, and from approximately $17.9 million to $25.5 million during the six months ended December 31, 2016 and 2017, respectively. The increases in cost of partnered programs are primarily attributed to increases in our portion of development costs relating to the BEACON study of binimetinib and encorafenib in partnership with Pierre Fabre, as well as costs associated with new and expanded collaborations with Amgen, Loxo and Mirati.
 
Research and Development Expenses for Proprietary Programs
 
Our research and development expenses for proprietary programs include costs associated with our proprietary drug programs, which primarily consist of personnel related expenses, including salaries, benefits, and other related expenses, stock-based compensation, payments made to third party contract research organizations for preclinical and clinical studies, investigative sites for clinical trials and consultants, the cost of acquiring and manufacturing clinical trial materials, costs associated with regulatory filings and patents, software and facilities, and laboratory costs and other supply costs.
