NOTE 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

Nature of Business and Recent Developments

Arrowhead Pharmaceuticals, Inc. develops medicines that treat intractable diseases by silencing the genes that cause them. Using a broad portfolio of RNA chemistries and efficient modes of delivery, Arrowhead therapies trigger the RNA interference mechanism to induce rapid, deep and durable knockdown of target genes. RNA interference (“RNAi”) is a mechanism present in living cells that inhibits the expression of a specific gene, thereby affecting the production of a specific protein. Arrowhead’s RNAi-based therapeutics leverage this natural pathway of gene silencing. The Company's pipeline includes ARO-APOC3 for hypertriglyceridemia, ARO-ANG3 for dyslipidemia, ARO-HSD for liver disease, ARO-ENaC for cystic fibrosis, ARO-HIF2 for renal cell carcinoma, ARO-LUNG2 as a candidate to treat chronic obstructive pulmonary disorder (“COPD”) and ARO-COV for treatment for the current novel coronavirus that causes COVID-19 and other possible future pulmonary-borne pathogens. ARO-JNJ1, ARO-JNJ2 and ARO-JNJ3 are being developed for undisclosed liver-expressed targets under a collaboration agreement with Janssen Pharmaceuticals, Inc. (“Janssen”). ARO-AAT for liver disease associated with alpha-1 antitrypsin deficiency (“AATD”) was out-licensed to Takeda Pharmaceuticals U.S.A., Inc. (“Takeda”) in October 2020. JNJ3989 (formerly referred to as ARO-HBV) for chronic hepatitis B virus was out-licensed to Janssen in October 2018. Olpasiran (formerly referred to as AMG 890 or ARO-LPA) for cardiovascular disease was out-licensed to Amgen Inc. (“Amgen”) in 2016.

Arrowhead operates lab facilities in Madison, Wisconsin and San Diego, California, where the Company’s research and development activities, including the development of RNAi therapeutics, are based. The Company’s principal executive offices are located in Pasadena, California.

During the first quarter of fiscal year 2021, the Company continued to develop its pipeline and partnered candidates. The Company hosted a key opinion leader webinar on its cardiometabolic candidates, ARO-APOC3 and ARO-ANG3. The Company presented positive interim clinical data from AROAAT2002, an open-label Phase 2 clinical study of ARO-AAT, the Company’s second-generation investigational RNAi therapeutic being developed as a treatment for the rare genetic liver disease associated with AATD. The Company also announced positive clinical data on its cardiometabolic candidates, ARO-APOC3 and ARO-ANG3, at the American Heart Association (“AHA”) Scientific Session 2020. Finally, the Company announced a collaboration with Takeda to co-develop and co-commercialize ARO-AAT for alpha-1 antitrypsin-associated liver disease. See Note 2 for more information regarding the collaboration with Takeda.

The Company’s partnered candidates under its collaboration agreements also continue to progress. Janssen began dosing patients in a Phase 2b triple combination study called REEF-1, designed to enroll up to 450 patients with chronic hepatitis B infection. In connection with the start of this study, Arrowhead earned a $25.0 million milestone payment under the Company’s License Agreement with Janssen (“Janssen License Agreement”). The Company is currently performing discovery, optimization and preclinical research and development for ARO-JNJ1, ARO-JNJ2 and ARO-JNJ3 for Janssen as part of the Company’s Research Collaboration and Option Agreement with Janssen (“Janssen Collaboration Agreement”). Under the terms of the Janssen agreements taken together, the Company has received $175.0 million as an upfront payment, $75.0 million in the form of an equity investment by Johnson & Johnson Innovation-JJDC, Inc. (“JJDC”) in Arrowhead Common Stock, two $25.0 million milestone payments and may receive up to $1.6 billion in development and sales milestones payments for the Janssen License Agreement, and up to $1.9 billion in development and sales milestone payments for the three additional targets covered under the Janssen Collaboration Agreement. The Company is further eligible to receive tiered royalties on product sales up to mid-teens under the Janssen License Agreement and up to low teens under the Janssen Collaboration Agreement.

The Company’s collaboration agreement with Amgen for Olpasiran (previously referred to as AMG 890 or ARO-LPA), (the “Second Collaboration and License Agreement” or “Olpasiran Agreement”), continues to progress. In July 2020, Amgen initiated a Phase 2 clinical study, which resulted in a $20.0 million milestone payment to the Company. The Company has received $35.0 million in upfront payments, $21.5 million in the form of an equity investment by Amgen in the Company’s Common Stock, $30.0 million in milestone payments, and may receive up to an additional $400.0 million in remaining development, regulatory and sales milestone payments. The Company is eligible to receive up to low double-digit royalties for sales of products under the Olpasiran Agreement.

On October 7, 2020, the Company entered into an Exclusive License and Co-Funding Agreement with Takeda (the “Takeda License Agreement”). Under the Takeda License Agreement, Takeda and the Company will co-develop the Company’s ARO-AAT program. Within the United States, ARO-AAT, if approved, will be co-commercialized under a 50/50 profit sharing structure. Outside the United States, Takeda will lead the global commercialization strategy and receive an exclusive license to commercialize ARO-AAT with the Company eligible to receive tiered royalties of 20% to 25% on net sales. In January 2021, the Company received $300.0 million as an upfront payment and is eligible to receive potential development, regulatory and commercial milestones of up to $740.0 million.

The revenue recognition for these collaboration agreements is discussed further in Note 2 below.

The Company is actively monitoring the ongoing COVID-19 pandemic. The financial results for the three months ended December 31, 2020 were not significantly impacted by COVID-19. During fiscal year 2020, the Company had temporarily paused enrollment in its two ARO-AAT studies, SEQUOIA and the ARO-AAT 2002 study, but resumed the process of screening and enrolling patients. During the pause in enrollment, patients already enrolled in these studies continued to be dosed per protocol and continued to come in for their follow up visits. Additional delays have occurred in the Company’s earlier stage programs, but the Company does not expect a material impact to any program’s anticipated timelines. Additionally, the Company’s operations at its research and development facilities in Madison, Wisconsin and San Diego, California, and its corporate headquarters in Pasadena, California have continued to operate with limited impact, other than for enhanced safety measures, including work from home policies. However, the Company cannot predict the impact the progression of COVID-19 will have on future financial results due to a variety of factors including the ability of the Company’s clinical sites to continue to enroll subjects, the ability of the Company’s suppliers to continue to operate, the continued good health and safety of the Company’s employees, and ultimately the length of the COVID-19 pandemic.

Liquidity

The Consolidated Financial Statements have been prepared in conformity with the accounting principles generally accepted in the United States of America (“GAAP”), which contemplate the continuation of the Company as a going concern. Historically, the Company’s primary source of financing has been through the sale of its securities. Research and development activities have required significant capital investment since the Company’s inception. The Company expects its operations to continue to require cash investment to pursue its research and development goals, including clinical trials and related drug manufacturing.

At December 31, 2020, the Company had $139.9 million in cash and cash equivalents (including $2.4 million in restricted cash), $79.4 million in short-term investments, $86.0 million in marketable securities and $110.9 million in long-term investments to fund operations. During the three months ended December 31, 2020, the Company’s cash and investments balance decreased by $36.8 million, which was primarily the result of funding its research and development operations.

Summary of Significant Accounting Policies

There have been no changes to the significant accounting policies disclosed in the Company’s most recent Annual Report on Form 10-K.

Recent Accounting Pronouncements

In November 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-18 Collaborative Arrangements (Topic 808). This update provides clarification on the interaction between Revenue Recognition (Topic 606) and Collaborative Arrangements (Topic 808) including the alignment of unit of account guidance between the two topics. ASU 2018-18 became effective for the Company on October 1, 2020 and did not have a material impact on its Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-15 Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The new standard requires that certain implementation costs for cloud computing arrangements are capitalized and amortized over the term of the associated hosted cloud computing arrangement service. Capitalized implementation costs are classified in prepaid expenses and other assets. The amortization of the capitalized asset is presented in the same line on the statement of operations and comprehensive loss as the fees for the associated hosted cloud computing arrangement service and not included with depreciation or amortization expense related to property and equipment or intangible assets. Cash flows related to capitalized implementation costs are presented in cash flows used in operating activities. ASU 2018-15 became effective for the Company on October 1, 2020 and did not have a material impact on its Consolidated Financial Statements.

NOTE 2. COLLABORATION AND LICENSE AGREEMENTS

Amgen Inc.

On September 28, 2016, the Company entered into two Collaboration and License Agreements and a Common Stock Purchase Agreement with Amgen. Under one of the collaboration and license agreements (the “Second Collaboration and License Agreement” or “Olpasiran Agreement”), Amgen has received a worldwide, exclusive license to Arrowhead’s novel, RNAi Olpasiran (previously referred to as AMG 890 or ARO-LPA) program. These RNAi molecules are designed to reduce elevated lipoprotein(a), which is a genetically validated, independent risk factor for atherosclerotic cardiovascular disease. Under the other collaboration and license agreement (the “First Collaboration and License Agreement” or the “ARO-AMG1 Agreement”), Amgen received an option to a worldwide, exclusive license for ARO-AMG1, an RNAi therapy for an undisclosed genetically validated cardiovascular target. In both agreements, Amgen is wholly responsible for clinical development and commercialization. Under the terms of the agreements taken together, the Company has received $35.0 million in upfront payments, $21.5 million in the form of an equity investment by Amgen in the Company’s Common Stock, and $30.0 million in milestone payments, and may receive up to an additional $400.0 million in remaining development, regulatory and sales milestone payments. The Company is further eligible to receive up to low double-digit royalties for sales of products under the Olpasiran Agreement. In July 2019, Amgen informed the Company that it would not be exercising its option for an exclusive license for ARO-AMG1, and as such, there will be no further milestone or royalty payments under the ARO-AMG1 Agreement.

The Company substantially completed its performance obligations under the Olpasiran Agreement and the ARO-AMG1 Agreement. Future milestones and royalties achieved will be recognized in their entirety when earned. In July 2020, Amgen initiated a Phase 2 clinical study, which resulted in a $20.0 million milestone payment to the Company. During the three months ended December 31, 2020 and 2019, the Company recognized $0 and $0, respectively. As of December 31, 2020, there were $0 in contract assets recorded as accounts receivable and $0 contract liabilities recorded as current deferred revenue on the Company’s Consolidated Balance Sheets.

Janssen Pharmaceuticals, Inc.

On October 3, 2018, the Company entered into the Janssen License Agreement and the Janssen Collaboration Agreement with Janssen, part of the Janssen Pharmaceutical Companies of Johnson & Johnson. The Company also entered into a Stock Purchase Agreement (“JJDC Stock Purchase Agreement”) with JJDC. Under the Janssen License Agreement, Janssen has received a worldwide, exclusive license to the Company’s JNJ-3989 (ARO-HBV) program, the Company’s third-generation subcutaneously administered RNAi therapeutic candidate being developed as a potential therapy for patients with chronic hepatitis B virus infection. Beyond the Company’s Phase 1/2 study of JNJ-3989 (ARO-HBV), Janssen is also wholly responsible for clinical development and commercialization of JNJ-3989. Under the Janssen Collaboration Agreement, Janssen will be able to select three new targets against which Arrowhead will develop clinical candidates. These candidates are subject to certain restrictions and do not include candidates that already were in the Company’s pipeline. The Company will perform discovery, optimization and preclinical research and development, entirely funded by Janssen, which on its own or in combination with Janssen development work, is sufficient to allow the filing of a U.S. Investigational New Drug application or equivalent, at which time Janssen will have the option to take an exclusive license. If the option is exercised, Janssen will be wholly responsible for clinical development and commercialization of each optioned candidate. Under the terms of the agreements taken together, the Company has received $175.0 million as an upfront payment, $75.0 million in the form of an equity investment by JJDC in Arrowhead Common Stock under the JJDC Stock Purchase Agreement, and two $25.0 million milestone payments, and may receive up to $1.6 billion in development and sales milestones payments for the Janssen License Agreement, and up to $1.9 billion in development and sales milestone payments for the three additional targets covered under the Janssen Collaboration Agreement. The Company is further eligible to receive tiered royalties up to mid-teens under the Janssen License Agreement and up to low teens under the Janssen Collaboration Agreement on product sales.

The Company has evaluated these agreements in accordance with the new revenue recognition standard that became effective for the Company on October 1, 2018. The adoption of the new revenue standard did not have a material impact on the balances reported when evaluated under the superseded revenue standard. At the inception of these agreements, the Company has identified one distinct performance obligation. Regarding the Janssen License Agreement, the Company determined that the key deliverables included the license and certain R&D services including the Company’s responsibility to complete the Phase 1/2 study of JNJ-3989 (ARO-HBV) and the Company’s responsibility to ensure certain manufacturing of JNJ-3989 (ARO-HBV) drug product is completed and delivered to Janssen (the “Janssen R&D Services”). Due to the specialized and unique nature of these Janssen R&D Services, and their direct relationship with the license, the Company determined that these deliverables represent one distinct bundle and thus, one performance obligation. The Company also determined that Janssen’s option to require the Company to develop up to three new targets is not a material right, and thus, not a performance obligation at the onset of the agreement. The consideration for this option is accounted for separately.

The Company determined the transaction price totaled approximately $252.6 million which includes the upfront payment, the premium paid by JJDC for its equity investment in the Company, the two $25.0 million milestone payments earned and estimated payments for reimbursable Janssen R&D services to be performed. The Company has allocated the total $252.6 million initial transaction price to its one distinct performance obligation for the JNJ-3989 (ARO-HBV) license and the associated Janssen R&D Services. This revenue will be recognized using a proportional performance method (based on actual costs incurred versus total estimated costs incurred) beginning in October 2018 and ending as the Company’s efforts in overseeing the Phase 1/2 clinical trial are completed. During the three months ended December 31, 2020 and 2019, the Company recognized approximately $12.7 million and $28.8 million of Revenue associated with this performance obligation, respectively. As of December 31, 2020, there were $0 in contract assets recorded as accounts receivable, and $6.7 million of contract liabilities recorded as current deferred revenue on the Company’s Consolidated Balance Sheets. The $6.7 million of current deferred revenue is driven by the upfront payment, the premium paid by JJDC for its equity investment in the Company, and the two $25.0 million milestone payments earned, net of revenue recognized to date.

The Company has begun to conduct its discovery, optimization and preclinical research and development of ARO-JNJ1, ARO-JNJ2 and ARO-JNJ3 under the Janssen Collaboration Agreement. All costs and labor hours spent by the Company will be entirely funded by Janssen. During the three months ended December 31, 2020 and 2019, the Company recognized $0.3 million and $0.7 million of Revenue associated with these efforts, respectively. As of December 31, 2020, there were $0.8 million of contract assets recorded as accounts receivable and $0 of contract liabilities recorded as current deferred revenue on the Company’s Consolidated Balance Sheets.

Takeda Pharmaceuticals U.S.A., Inc.

On October 7, 2020, the Company entered into the Takeda License Agreement with Takeda. Under the Takeda License Agreement, Takeda and the Company will co-develop the Company’s ARO-AAT program, the Company’s second-generation subcutaneously administered RNAi therapeutic candidate being developed as a treatment for liver disease associated with alpha-1 antitrypsin deficiency. Within the United States, ARO-AAT, if approved, will be co-commercialized under a 50/50 profit sharing structure. Outside the United States, Takeda will lead the global commercialization strategy and receive an exclusive license to commercialize ARO-AAT with the Company eligible to receive tiered royalties of 20% to 25% on net sales. In January 2021, the Company received $300.0 million as an upfront payment and is eligible to receive potential development, regulatory and commercial milestones of up to $740.0 million.

The Company has evaluated the Takeda License Agreement in accordance with the new revenue recognition requirements that became effective for the Company on October 1, 2018. The adoption of the new revenue standard will not have a material impact on the balances reported when evaluated under the superseded revenue standard. At the inception of the Takeda License Agreement, the Company has identified one distinct performance obligation. The Company determined that the key deliverables included the license and certain R&D services including the Company’s responsibilities to complete the initial portion of the SEQUOIA study, to complete the ongoing Phase 2 AROAAT2002 study and to ensure certain manufacturing of ARO-AAT drug product is completed and delivered to Takeda (the “Takeda R&D Services”). Due to the specialized and unique nature of these Takeda R&D services, and their direct relationship with the license, the Company determined that these deliverables represent one distinct bundle and thus, one performance obligation. Beyond the Takeda R&D Services, Takeda will be responsible for managing future clinical development and commercialization. The Company will co-fund certain of the development and commercialization costs that Takeda manages, and these co-funding amounts will be offset against amounts owed to Arrowhead, either from milestones or royalties earned, or profits earned under the 50/50 profit sharing structure for U.S. commercialization.

The Company determined the initial transaction price totaled approximately $300.0 million, which includes the upfront payment. The Company will exclude any future estimated milestones, royalties, or profit-sharing payments from this transaction price to date. The Company will allocate the total $300.0 million initial transaction price to its one distinct performance obligation for the ARO-AAT license and the associated Takeda R&D Services. Revenue will be recognized using a proportional performance method (based on actual costs incurred versus total estimated costs incurred for the Takeda R&D Services). Revenue for the three months ended December 31, 2020 and 2019 were $8.2 million and $0, respectively. As of December 31, 2020, there were $8.2 million in contract assets recorded as accounts receivable.

NOTE 7. COMMITMENTS AND CONTINGENCIES

Litigation

From time to time, the Company may be subject to various claims and legal proceedings in the ordinary course of business. If the potential loss from any claim, asserted or unasserted, or legal proceeding is considered probable and the amount is reasonably estimable, the Company will accrue a liability for the estimated loss. There were no contingent liabilities recorded as of the three months ended December 31, 2020.

Purchase Commitments

In the normal course of business, the Company enters into various purchase commitments for the manufacture of drug components, for toxicology studies and for clinical studies. As of December 31, 2020, these future commitments were estimated at approximately $100.2 million, of which approximately $85.0 million is expected to be incurred in remaining fiscal year 2021.

Technology License Commitments

The Company has licensed from third parties the rights to use certain technologies for its research and development activities, as well as in any products the Company may develop using these licensed technologies. These agreements and other similar agreements often require milestone and royalty payments. Milestone payments, for example, may be required as the research and development process progresses through various stages of development, such as when clinical candidates enter or progress through clinical trials, upon a new drug application and upon certain sales level milestones. These milestone payments could amount to the mid to upper double-digit millions of dollars. During the three months ended December 31, 2020 and 2019, the Company did not reach any milestones. In certain agreements, the Company may be required to make mid to high single-digit percentage royalty payments based on a percentage of the sales of the relevant products.

NOTE 8. LEASES

Leases

In April 2019, the Company entered into a lease for its corporate headquarters in Pasadena, California. The 91 month office building lease between the Company and 177 Colorado Owner, LLC is for approximately 24,000 square feet of office space located at 177 E. Colorado Blvd, Pasadena, California. The increased capacity of this new office space compared to the Company’s prior corporate headquarters will accommodate increased personnel as the Company’s pipeline of drug candidates expands and moves closer to market. Lease payments began on September 30, 2019 and are estimated to total approximately $8.7 million over the term. The lease expires on April 30, 2027. The Company has paid approximately $3.5 million for leasehold improvements, net of tenant improvement allowances. The lease contains an option to renew for one term of five years. The exercise of this option was not determined to be reasonably certain and thus was not included in lease liabilities on the Company’s Consolidated Balance Sheet at December 31, 2020. On October 23, 2020, the Company signed a lease expansion to add an additional approximately 24,000 square feet of office space at the same location for its corporate headquarters. The lease commencement date is expected to be in July 2021, after certain leasehold improvements are completed, and the lease expires in April 2027. The lease payments for the expansion are expected to total $6.9 million. The Company anticipates paying approximately $4.0 million of leasehold improvements, net of tenant improvement allowances. The increased capacity of this additional office space compared to the Company’s current corporate headquarters will accommodate increased personnel as the Company’s pipeline of drug candidates expands and moves closer to market.

In January 2016, the Company entered into a lease for its research facility in Madison, Wisconsin. The lease was for approximately 60,000 square feet of office and laboratory space and had an expiration date of September 30, 2026. The lease was amended in January 2019 and May 2020 to expand the rentable square feet by an additional 40,000 total square feet and extended the lease expiration date to September 30, 2031. Lease payments are estimated to total approximately $26.2 million for the term. The Company anticipates paying approximately $11.0 million of leasehold improvements for the additional 40,000 square feet, net of tenant improvement allowances. The lease contains two options to renew for two terms of five years. The exercise of these options were not determined to be reasonably certain and thus was not included in lease liabilities on the Company’s Consolidated Balance Sheet at December 31, 2020. In November 2020 and December 2020, two amendments were signed to expand the rentable square space by an additional 10,743 square feet and these amendments added a total of approximately $1.2 million of lease payments for the remainder of the term.

In March 2020, the Company entered into a sublease agreement (the “Sublease”) with Halozyme, Inc. for additional research and development facility space in San Diego, California. The Sublease provides additional space needed to accommodate the recent growth of the Company’s personnel and discovery efforts. The sublease is for approximately 21,000 rentable square feet. The term of the Sublease commenced on April 1, 2020 and will end on January 14, 2023. Sublease payments are estimated to total approximately $2.0 million over the term.

Operating lease cost during the three months ended December 31, 2020 and 2019 was $0.9 million and $0.5 million, respectively. Variable lease costs for the three months ended December 31, 2020 and 2019 was $0.2 million and $0.2 million, respectively. There was no short-term lease cost during the three months ended December 31, 2020 and 2019.

The following table presents maturities of operating lease liabilities on an undiscounted basis as of December 31, 2020:

	(in thousands)
2021 (remainder of fiscal year)	$	2,379
2022		3,853
2023		3,406
2024		3,269
2025		3,358
2026 and thereafter		15,331
Total	$	31,596
Less imputed interest	$	(10,728	)
Total operating lease liabilities (includes current portion)	$	20,868

Cash paid for the amounts included in the measurement of the operating lease liabilities on the Company’s Consolidated Balance Sheet and included in Other changes in operating assets and liabilities within cash flows from operating activities on the Company’s Consolidated Statement of Cash Flow for the three months ended December 31, 2020 and 2019 was $0.7 million and $0.3 million, respectively. The weighted-average remaining lease term and weighted-average discount rate for all leases as of December 31, 2020 was 9.2 years and 8.4%, respectively.

NOTE 9. STOCK-BASED COMPENSATION

Arrowhead has two plans that provide for equity-based compensation. Under the 2004 Equity Incentive Plan and the 2013 Incentive Plan, as of December 31, 2020, 509,210 and 5,102,360 shares, respectively, of Arrowhead’s Common Stock are reserved for the grant of stock options, stock appreciation rights, restricted stock awards and performance unit/share awards to employees, consultants and others. No further grants may be made under the 2004 Equity Incentive Plan. As of December 31, 2020, there were options granted and outstanding to purchase 509,210 and 2,320,640 shares of Common Stock under the 2004 Equity Incentive Plan and the 2013 Incentive Plan, respectively, and there were 2,385,200 restricted stock units granted and outstanding under the 2013 Incentive Plan. Also, as of December 31, 2020, there were 1,260,503 shares reserved for options and 762,950 shares reserved for restricted stock units issued as inducement grants to new employees outside of equity compensation plans.

The following table summarizes information about stock options:

	Number of Options Outstanding			Weighted- Average Exercise Price Per Share		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value
Balance at September 30, 2020		4,539,403		$	16.67
Granted		144,000		63.64
Cancelled		(55,438	)	24.48
Exercised		(537,612	)	9.49
Balance at December 31, 2020		4,090,353		$	19.16	6.3 years	$	235,465,861
Exercisable at December 31, 2020		2,556,040		$	9.56	4.8 years	$	171,695,135

Stock-based compensation expense related to stock options for the three months ended December 31, 2020 and 2019 was $3.1 million and $1.6 million, respectively. For non-qualified stock options, the expense creates a timing difference, resulting in a deferred tax asset, which is fully reserved by a valuation allowance.

The grant date fair value of the options granted by the Company for the three months ended December 31, 2020 and 2019 was $6.8 million and $8.6 million, respectively.

The intrinsic value of the options exercised during the three months ended December 31, 2020, and 2019 was $32.0 million and $21.6 million, respectively.

As of December 31, 2020, the pre-tax compensation expense for all outstanding unvested stock options in the amount of $39.0 million will be recognized in the Company’s results of operations over a weighted average period of 3.1 years.

The fair value of each stock option award is estimated on the date of grant using the Black-Scholes option pricing model. The Black-Scholes option valuation model was developed for use in estimating the fair value of traded options, which do not have vesting restrictions and are fully transferable. The determination of the fair value of each stock option is affected by the Company’s stock price on the date of grant, as well as assumptions regarding a number of highly complex and subjective variables. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of its employee stock options.

The assumptions used to value stock options are as follows:

	Three Months Ended December 31,
	2020		2019
Dividend yield		-		-
Risk-free interest rate	0.4 – 0.6%		1.4 - 1.8%
Volatility	90.0-90.4%		90.5-91.0%
Expected life (in years)		6.25		6.25
Weighted average grant date fair value per share of options granted	$	47.34	$	39.05

The dividend yield is zero as the Company currently does not pay a dividend.

The risk-free interest rate is based on that of the U.S. Treasury bond.

Volatility is estimated based on volatility average of the Company’s Common Stock price.

Restricted Stock Units

Restricted stock units (“RSUs”), including time-based and performance-based awards, were granted under the Company’s 2013 Incentive Plan and as inducements grants granted outside of the Plan. During the three months ended December 31, 2020, the Company issued 2,200 RSUs under the 2013 Incentive Plan and 116,000 RSUs as inducement awards. At vesting, each outstanding RSU will be exchanged for one share of the Company’s Common Stock. RSU recipients may elect to net share settle upon vesting, in which case the Company pays the employee’s income taxes due upon vesting and withholds a number of shares of Common Stock of equal value. RSU awards generally vest subject to the satisfaction of service requirements or the satisfaction of both service requirements and achievement of certain performance targets.

The following table summarizes the activity of the Company’s RSUs:

	Number of RSUs			Weighted- Average Grant Date Fair Value
Unvested at September 30, 2020		3,524,025		$	44.11
Granted		118,200			62.26
Vested		(280,325	)		22.92
Forfeited		(213,750	)		41.34
Unvested at December 31, 2020		3,148,150		$	46.87

During the three months ended December 31, 2020 and 2019, the Company recorded $5.0 million and $2.9 million of expense related to RSUs, respectively. Such expense is included in stock-based compensation expense in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss). For RSUs, the expense creates a timing difference, resulting in a deferred tax asset, which is fully reserved by a valuation allowance.

For RSUs, the grant date fair value of the award is based on the Company’s closing stock price at the grant date, with consideration given to the probability of achieving performance conditions for performance-based awards.

As of December 31, 2020, the pre-tax compensation expense for all unvested RSUs in the amount of $82.0 million will be recognized in the Company’s results of operations over a weighted average period of 3.0 years. Unvested RSUs that we have deemed not probable of vesting as of December 31, 2020, have the potential of generating an additional $38.1 million of pre-tax compensation expense if we deem them probable of vesting in a future reporting period.

NOTE 10. FAIR VALUE MEASUREMENTS

The Company measures its financial assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., exit price) in an orderly transaction between market participants at the measurement date. Additionally, the Company is required to provide disclosure and categorize assets and liabilities measured at fair value into one of three different levels depending on the assumptions (i.e., inputs) used in the valuation. Level 1 provides the most reliable measure of fair value while Level 3 generally requires significant management judgment. Financial assets and liabilities are classified in their entirety based on the lowest level of input significant to the fair value measurement. The fair value hierarchy is defined as follows:

Level 1—Valuations are based on unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2—Valuations are based on quoted prices for similar assets or liabilities in active markets, or quoted prices in markets that are not active for which significant inputs are observable, either directly or indirectly.

Level 3—Valuations are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Inputs reflect management’s best estimate of what market participants would use in valuing the asset or liability at the measurement date.

The following table summarizes fair value measurements at December 31, 2020 and September 30, 2020 for assets and liabilities measured at fair value on a recurring basis.

Description of Business

Overview

Arrowhead has focused its resources on therapeutics that exclusively utilize the Company’s Targeted RNAi Molecule (TRiM^TM) platform technology. Therapeutics built on the TRiM^TM platform have demonstrated high levels of pharmacologic activity in multiple animal models spanning several therapeutic areas. TRiM^TM enabled therapeutics offer several potential advantages over prior generation and competing technologies, including: simplified manufacturing and reduced costs; multiple routes of administration including subcutaneous injection and inhaled administration; the ability to target multiple tissue types including liver, lung and tumors; and the potential for improved safety and reduced risk of intracellular buildup, because there are less metabolites from smaller, simpler molecules.

During the first quarter of fiscal year 2021, the Company continued to develop its pipeline and partnered candidates. The Company hosted a key opinion leader webinar on its cardiometabolic candidates, ARO-APOC3 and ARO-ANG3. The Company presented positive interim clinical data from AROAAT2002, an open-label Phase 2 clinical study of ARO-AAT, the Company’s second-generation investigational RNAi therapeutic being developed as a treatment for the rare genetic liver disease associated with AATD. The Company also announced positive clinical data on its cardiometabolic candidates, ARO-APOC3 and ARO-ANG3, at the American Heart Association (“AHA”) Scientific Session 2020. Finally, the Company announced a collaboration with Takeda to co-develop and co-commercialize ARO-AAT for alpha-1 antitrypsin-associated liver disease. See Note 2 of the Notes to Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for more information regarding the collaboration with Takeda.

The Company’s collaboration agreement with Amgen for Olpasiran (previously referred to as AMG 890 or ARO-LPA), (the “Second Collaboration and License Agreement” or “Olpasiran Agreement”) continues to progress. In July 2020, Amgen initiated a Phase 2 clinical study, which resulted in a $20.0 million milestone payment to the Company. The Company has received $35.0 million in upfront payments, $21.5 million in the form of an equity investment by Amgen in the Company’s Common Stock, $30.0 million in milestone payments, and may receive up to an additional $400.0 million in remaining development, regulatory and sales milestone payments. The Company is eligible to receive up to low double-digit royalties for sales of products under the Olpasiran Agreement.

The revenue recognition for these collaboration agreements is discussed further in Note 2 of the Notes to Consolidated Financial Statements of Part I, Item 1. Financial Statements of this Quarterly Report on Form 10-Q.

The Company continues to develop other clinical candidates for future clinical trials. Clinical candidates are tested internally and through GLP toxicology studies at outside laboratories. Drug materials for such studies and clinical trials are either contracted to third-party manufactures or manufactured internally. The Company engages third-party contract research organizations (“CROs”) to manage clinical trials and works cooperatively with such organizations on all aspects of clinical trial management, including plan design, patient recruiting, and follow up. These outside costs, relating to the preparation for and administration of clinical trials, are referred to as “candidate costs.” If the clinical candidates progress through human testing, candidate costs will increase.

Net losses were $20.7 million for the three months ended December 31, 2020 as compared to net losses of $2.7 million for the three months ended December 30, 2019. Net losses per share-diluted were $0.20 for the three months ended December 31, 2020 as compared to net losses per share-diluted of $0.03 for the three months ended December 31, 2019. An increase in research and development and general and administrative expenses coupled with a decrease in revenue from the license and collaboration agreements with Janssen were the drivers of the increase in net losses and net losses per share for the three months ended December 31, 2020, as discussed further below.

The Company has strengthened its liquidity and financial position through upfront and milestone payments received under its collaboration agreements, as well as equity financings. Under the terms of the Company’s agreements with Janssen taken together, the Company has received $175.0 million as an upfront payment, $75.0 million in the form of an equity investment by JJDC in Arrowhead Common Stock and two $25.0 million milestone payments. Under the terms of the Company’s agreements with Amgen, the Company has received $35.0 million in upfront payments, $21.5 million in the form of an equity investment by Amgen in the Company’s Common Stock and $30.0 million in milestone payments. The Company’s October 2020 licensing agreement with Takeda will result in a $300.0 million upfront payment, which has been collected in the beginning of the second quarter of 2021. Additionally, in December 2019, the Company completed a securities offering which generated approximately $250.5 million in net cash proceeds. These cash proceeds secure the funding needed to continue to advance our pipeline candidates. The Company had $139.9 million of cash and cash equivalents, $86.0 million of marketable securities, $79.4 million in short-term investments, $110.9 million of long term investments and $499.3 million of total assets as of December 31, 2020, as compared to $143.6 million, $85.0 million, $86.9 million, $137.5 million and $522.5 million as of September 30, 2020, respectively. Based upon the Company’s current cash and investment resources and operating plan, the Company expects to have sufficient liquidity to fund operations for at least the next twelve months.

Results of Operations

The following data summarizes our results of operations for the following periods indicated:

	Three Months Ended December 31,
	2020			2019
	(in thousands, except per share amounts)
Revenues	$	21,303		$	29,455
Operating Income (loss)	$	(24,054	)	$	(4,853	)
Net Income (loss)	$	(20,732	)	$	(2,673	)
Net Income (Loss) per Share- Diluted	$	(0.20	)	$	(0.03	)

The decrease in revenue for the three months ended December 31, 2020 compared to the three months ended December 31, 2019 was driven by the timing of the recognition of the $252.6 million initial transaction price associated with our agreements with Janssen and JJDC as we achieved progress toward completing our performance obligation under those agreements; partially offset by the revenue recognized for the Takeda collaboration. The increase in Net Losses during the three months ended December 31, 2020 compared to the three months ended December 31, 2019 was driven by this decrease in Revenue and also increases in Research and Development Expenses as our pipeline of clinical candidates has continued to increase.

Revenue

Total revenue for the three months ended December 31, 2020 and 2019 was $21.3 million and $29.5 million, respectively. Revenue in the current period is primarily related to the recognition of a portion of the $252.6 million initial transaction price associated with our agreements with Janssen and JJDC as we achieved progress towards completing our performance obligation under those agreements. In addition, revenue in the current period consisted of $8.2 million of revenue associated with the Takeda collaboration. Revenue for the three months ended December 31, 2019, was primarily related to the recognition of a portion of the $252.6 million initial transaction price associated with our agreements with Janssen and JJDC. A higher proportion of performance activity was ongoing during the prior period than the current period, which resulted in the higher revenue recognized in the prior period.

Amgen Inc.

Janssen Pharmaceuticals, Inc.

Takeda Pharmaceuticals U.S.A., Inc.

On October 7, 2020, the Company entered into Takeda License Agreement with Takeda. Under the Takeda License Agreement, Takeda and the Company will co-develop the Company’s ARO-AAT program, the Company’s second-generation subcutaneously administered RNAi therapeutic candidate being developed as a treatment for liver disease associated with alpha-1 antitrypsin deficiency. Within the United States, ARO-AAT, if approved, will be co-commercialized under a 50/50 profit sharing structure. Outside the United States, Takeda will lead the global commercialization strategy and receive an exclusive license to commercialize ARO-AAT with the Company eligible to receive tiered royalties of 20% to 25% on net sales. In January 2021, the Company received $300.0 million as an upfront payment and is eligible to receive potential development, regulatory and commercial milestones of up to $740.0 million.

Operating Expenses

The analysis below details the operating expenses and discusses the expenditures of the Company within the major expense categories. Certain reclassifications have been made to prior-period operating expense categories to conform to the current period presentation. For purposes of comparison, the amounts for the three months ended December 31, 2020 and 2019 are shown in the tables below.

Research and Development Expenses

R&D expenses are related to the Company’s research and development efforts, and related program costs which are comprised primarily of outsourced costs related to the manufacturing of clinical supplies, toxicity/efficacy studies and clinical trial expenses. Internal costs primarily relate to operations at our research facilities in Madison, Wisconsin and San Diego, California, including facility costs and laboratory-related expenses. Salaries and stock compensation expense consist of salary, bonuses, payroll taxes and related benefits and stock compensation for our R&D personnel. Depreciation and amortization expense relates to depreciation on lab equipment and leasehold improvements at our research facilities. The following table provides details of research and development expenses for the periods indicated:

(table below in thousands)

	Three					Three
	Months Ended		% of Expense			Months Ended		% of Expense			Increase (Decrease)
	December 31, 2020		Category			December 31, 2019		Category			$		%
Salaries	$	8,173		22	%	$	4,096		18	%	$	4,077		100	%
Facilities related		1,478		4	%		620		3	%		858		138	%
Candidate costs		15,017		41	%		13,430		58	%		1,587		12	%
R&D discovery costs		4,711		13	%		2,955		13	%		1,756		59	%
Total research and development expense, excluding non-cash expense		29,379		80	%		21,101		90	%		8,278		39	%
Stock compensation		5,486		15	%		1,162		5	%		4,324		372	%
Depreciation/amortization		1,690		5	%		1,111		5	%		579		52	%
Total research and development expense	$	36,555		100	%	$	23,374		100	%	$	13,181		56	%

Salaries expense increased by $4,077,000 from $4,096,000 during the three months ended December 31, 2019 to $8,173,000 during the current period. This increase is primarily due to an increase in R&D headcount that has occurred as the Company has expanded its pipeline of candidates.

Facilities expense increased by $858,000 from $620,000 during the three months ended December 31, 2019 to $1,478,000 during the current period. This category includes rental costs for our research and development facilities in Madison, Wisconsin and San Diego, California. This increase is primarily due the commencement of our sublease in San Diego, California in April 2020.

Candidate costs increased by $1,587,000 from $13,430,000 during the three months ended December 31, 2019 to $15,017,000 during the current period. This increase is primarily due to the progression of our pipeline candidates into and through clinical trials, which results in higher outsourced clinical trial, toxicity study and manufacturing costs. We anticipate these expenses to continue to increase as our pipeline of candidates grows and progresses to later phase clinical trials.

R&D discovery costs increased by $1,756,000 from $2,955,000 during the three months ended December 31, 2019 to $4,711,000 in the current period. This increase is due to the growth of our discovery efforts, including the addition of our research facility in San Diego. We anticipate this expense to continue to increase as we increase headcount to support our discovery efforts to identify new drug candidates.

Stock compensation expense, a non-cash expense, increased by $4,324,000 from $1,162,000 during the three months ended December 31, 2019 to $5,486,000 during the current period. Stock compensation expense is based upon the valuation of stock options and restricted stock units granted to employees, directors and certain consultants. Many variables affect the amount expensed, including the Company’s stock price on the date of the grant, as well as other assumptions. The increase in the expense in the current period is primarily due to the increased headcount discussed above and a mix of higher grant date fair values of awards amortizing during the current period due to the Company’s stock price at the time of the grants.

Depreciation and amortization expense, a non-cash expense, increased by $579,000 from $1,111,000 during the three months ended December 31, 2019 to $1,690,000 during the current period. The majority of depreciation and amortization expense relates to depreciation on lab equipment and leasehold improvements at our Madison research facility.

General & Administrative Expenses

The following table provides details of our general and administrative expenses for the periods indicated:

(table below in thousands)

	Three					Three
	Months Ended		% of Expense			Months Ended		% of Expense			Increase (Decrease)
	December 31, 2020		Category			December 31, 2019		Category			$			%
Salaries	$	2,584		29	%	$	4,081		37	%	$	(1,497	)		-37	%

Other G&A		694		8	%		760		7	%		(66	)		-9	%
Total general & administrative expense, excluding non-cash expense		5,990		68	%		7,456		1			(1,466	)		-45	%
Stock compensation		2,658		30	%		3,330		31	%		(672	)		-20	%
Depreciation/amortization		154		2	%		148		1	%		6			4	%
Total general & administrative expense	$	8,802		100	%	$	10,934		100	%	$	(2,132	)		-61	%

Salaries expense decreased by $1,497,000 from $4,081,000 during the three months ended December 31, 2019 to $2,584,000 during the current period. The decrease is primarily due to higher annual performance bonuses awarded in December 2019. We expect salaries expense to increase as our headcount continues to increase to help support our expanding clinical pipeline.

Professional/outside services include legal, accounting, consulting, patent expenses, business insurance expenses and other outside services retained by the Company. Professional/outside services expense increased by $160,000 from $1,822,000 during the three months ended December 31, 2019 to $1,982,000 during the current period. The increase is primarily related to certain patent-related expenses.

Facilities-related expense decreased by $63,000 from $793,000 during the three months ended December 31, 2019 to $730,000 during the current period. This category primarily includes rental costs for our corporate headquarters in Pasadena, California. The decrease in the expense in the current period is primarily related to the moving costs we incurred in the three months ended December 31, 2019 to move to our new corporate headquarters.

Other G&A expense decreased by $66,000 from $760,000 during the three months ended December 31, 2019 to $694,000 during the current period. This category consists primarily of travel, communication and technology, office expenses, and franchise and property tax expenses. The decrease in the expense was due to decreased travel expenses.

Stock compensation expense, a non-cash expense, decreased by $672,000 from $3,330,000 during the three months ended December 31, 2019 to $2,658,000 during the current period. Stock compensation expense is based upon the valuation of stock options and restricted stock units granted to employees, directors and certain consultants. Many variables affect the amount expensed, including the Company’s stock price on the date of the grant, as well as other assumptions. We expect future stock compensation expense to increase as our headcount continues to increase to help support our clinical pipeline.

Depreciation and amortization expense, a noncash expense, increased by $6,000 from $148,000 during the three months ended December 31, 2019 to $154,000 during the current period. The increase is primarily related to amortization of leasehold improvements for our new corporate headquarters.

Other Income/Expense

Other income/expense was income of $2,180,000 during the three months ended December 31, 2019 compared to income of $3,322,000 during the current period. Other income is primarily related to interest income and gain/loss on our marketable securities. The increase in other income is consistent with the increase in our investment holdings.

Liquidity and Capital Resources

Arrowhead has historically financed its operations through the sale of its equity securities. Research and development activities have required significant capital investment since the Company’s inception and are expected to continue to require significant cash expenditure in the future.

At December 31, 2020, the Company had cash on hand of approximately $139.9 million as compared to $143.6 million at September 30, 2020. Cash invested in short-term fixed income securities and marketable securities was $165.4 million at December 31, 2020, compared to $171.9 million at September 30, 2020. Cash invested in long-term fixed income securities was $110.9 million at December 31, 2020, compared to $137.5 million at September 30, 2020. The Company also entered into an Open Market Sale Agreement (the “ATM agreement”), pursuant to which the Company may, from time to time, sell up to $250,000,000 in shares of the Company’s common stock through Jefferies LLC. As of December 31, 2020, no shares have been issued under the ATM agreement. The Company believes its current financial resources are sufficient to fund its operations through at least the next twelve months.

A summary of cash flows for the three months ended December 31, 2020 and 2019 is as follows:

	Three Months Ended		Three Months Ended
	December 31, 2020		December 31, 2019

Cash and cash equivalents at end of period		139,921		461,032

During the three months ended December 31, 2020, the Company used $38.9 million in cash from operating activities, which was primarily related to the ongoing expenses of the Company’s research and development programs and general and administrative expenses. Cash provided in investing activities was $30.2 million, which was primarily related to the sale of marketable securities of $34.4 million, partially offset by the purchase of property and equipment of $4.3 million. Cash provided by financing activities of $5.1 million was related to cash received from stock option exercises.

During the three months ended December 31, 2019, the Company used $23.5 million in cash from operating activities, which was primarily related to the ongoing expenses of the Company’s research and development programs and general and administrative expenses. Cash provided by investing activities was $9.3 million, which was primarily related to maturities of fixed-income investments of $13.6 million, partially offset by capital expenditures of $4.3 million. Cash provided by financing activities of $253.5 million was driven by the securities financing in December 2019, which generated $250.5 million in net cash proceeds, as well as $3.0 million in cash received from stock option exercises.
