The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the financial statements and notes included in Part IV, Item 15 of this Annual Report on Form 10-K. In addition to historical financial information, the following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Our actual results could differ materially from those discussed in the forward-looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report, including, but not limited to, those set forth in "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors."
Overview
We are a clinical-stage biotechnology company that uses a proprietary gene therapy platform to develop transformational genetic therapies for people suffering from rare and debilitating diseases. Our initial focus is in the field of ophthalmology, where we have active clinical programs in X-linked retinitis pigmentosa ("XLRP"), achromatopsia ("ACHM") and optogenetics, as well as a preclinical program in age-related maculardegeneration ("AMD"). In addition to ophthalmology, we have initiated one preclinical program in otology and two preclinical programs targeting central nervous system disorders ("CNS"), including frontotemporal dementia ("FTD") and amyotrophic lateral sclerosis ("ALS"). Our optogenetics program is being developed in collaboration withBionic Sight, LLC ("Bionic Sight") and our otology program is being developed in collaboration with Otonomy, Inc. ("Otonomy"). With a number of important clinical milestones on the horizon, we believe that we are well 92
--------------------------------------------------------------------------------

positioned to advance multiple programs toward pivotal studies. In addition to our product pipeline, we have also developed broad technological and manufacturing capabilities utilizing both our internal scientific resources and collaborations with others, such as our efforts with theUniversity of Florida , which provides us with expertise in vector design and access to novel capsids. Since our inception, we have devoted substantially all of our resources to development efforts relating to our proof-of-concept programs in ophthalmology, otology, CNS, and alpha-1 antitrypsin deficiency, an inherited orphan lung disease, including manufacturing product in compliance with good manufacturing practices, preparing to conduct and conducting clinical trials of our product candidates, providing general and administrative support for these operations and protecting our intellectual property. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations to date primarily through public offerings of our common stock and warrants to purchase our common stock, private placements of our preferred stock, collateralized borrowing and collaborations. We have also been the recipient, either independently or with our collaborators, of grant funding administered through federal, state, and local governments and agencies, including theUnited States Food and Drug Administration , or FDA, and by patient advocacy groups such asThe Foundation Fighting Blindness and theAlpha-1 Foundation . We have incurred losses from operations in each year since inception, except for fiscal year 2017, wherein we reported net income of$0.4 million due, in part, to profits from a collaboration agreement that was ultimately terminated inMarch 2019 . For the years endedJune 30, 2021 and 2020, we reported net losses of$57.8 million and$45.9 million , respectively. Substantially all our net losses resulted from costs incurred in connection with our research and development programs and general and administrative and other expenses associated with our operations. We expect to continue to incur significant operating expenses for at least the next several years and anticipate that such expenses will increase substantially in connection with our ongoing activities as we: • continue to conduct preclinical studies and clinical trials for our XLRP and ACHM product candidates and preclinical studies for our other ophthalmology, otology and CNS product candidates;
• continue our research and development efforts, including exploration
through early preclinical studies of potential applications of our gene therapy platform in: • orphan ophthalmology indications;
• non-orphan ophthalmology indications, including AMD and other retinal
diseases; and • other inherited diseases, such as otology and CNS indications; • manufacture clinical trial materials and develop larger-scale
manufacturing capabilities, including the lease of a new build-to-suit
manufacturing and quality control facility; • seek regulatory approval for our product candidates; • further develop our gene therapy platform; • add personnel to support our scientific, collaboration, product development and commercialization efforts; and • continue to operate as a public company. As ofJune 30, 2021 , we had cash and cash equivalents and liquid investments totaling$107.1 million . We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates, which we expect will take a number of years and which we believe is subject to significant uncertainty. We believe that our available cash and cash equivalents and investments will be sufficient to allow us to generate data from our ongoing and planned clinical programs and fund currently planned research and discovery programs into calendar year 2023. In order to complete the XLRP Phase 2/3 ("Vista") trial, move our ACHMB3 product candidate forward, obtain regulatory approval for our lead product candidates and build the sales, marketing and distribution infrastructure that we believe will be 93
--------------------------------------------------------------------------------

necessary to commercialize our lead product candidates, if approved, we will require substantial additional funding. Also, our current operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements, acquisitions or other business development activities, or a combination of these approaches. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements as and when needed would have a negative impact on our financial condition and our ability to develop our product candidates and continue our research and development efforts.
Recent Developments
XLRP
InNovember 2020 , we announced a modification to the primary endpoint for our Vista and Phase 1/2 Expansion ("Skyline") trials based on comments received from the FDA. The design of our Vista trial is expected to include approximately 60 patients randomized across three arms: a low-dose group (the 1.2E+11 vg/mL Group 2 dose from the ongoing Phase 1/2 trial), a high-dose group (the 1.1E+12 vg/mL Group 5 dose from the ongoing Phase 1/2 trial) and an untreated control group. The primary endpoint will be visual sensitivity defined as having at least a 7 decibel improvement in visual sensitivity in at least 5 pre-specified loci at Month 12. Together with a third-party vendor, we have developed a machine learning algorithm that, on a patient-by-patient basis, predicts the loci most likely to improve through evaluation of baseline visual sensitivity. The algorithm was developed using the microperimetry data available to date from the Phase 1/2 dose escalation study. Secondary endpoints include mean change in visual sensitivity, improvements in visual acuity and improvements in performance on a visual navigation course. We also plan to include a masked interim analysis at Month 6, with that data expected to be released in the fourth quarter of calendar year 2022, which may provide us with the opportunity to adjust the trial, if necessary, to optimize outcomes. InNovember 2020 , we also provided additional data from our XLRP Phase 1/2 trial that indicated 2 of 8 evaluable centrally dosed patients in Groups 2 and 4 were responders at Month 12. A third patient, who was a responder at Month 6, fell just below the responder criterion. All eight evaluable patients also showed stable or improving visual acuity. In addition, we provided six-month data for the 11 centrally dosed patients in Groups 5 and 6 and reported that 5 of 11 patients were responders at Month 6. Nine of these patients also had stable or improving visual acuity. If we apply the planned Vista trial inclusion criteria, 3 of the 11 patients in Groups 5 and 6 would be removed from the analysis, and 5 of 8 patients, or 62%, would be considered responders. We do not have a control arm in the Phase 1/2 trial, which will be part of our Vista trial and necessary to evaluate efficacy. InMay 2021 , we provided 12-month data from our XLRP Phase 1/2 trial from seven patients in Group 5 and four patients in Group 6. One patient in Group 5 and two patients in Group 6 would not meet the inclusion criteria for the Skyline and Vista trials, resulting in a total of eight patients who were included in the responder analysis. Four of these eight patients (50%) were considered responders, all four of whom met the strict criteria of at least a 7 decibel improvement in at least 5 loci. One additional patient did not meet these criteria but had a statistically significant improvement in retinal sensitivity in the treated eye compared with the untreated eye at 12 months. Consistent with previously reported 6-month data from Groups 2, 4, 5 and 6, assessment of Best Corrected Visual Acuity ("BCVA") in these groups at 12 months continues to provide supportive evidence of improved visual acuity in these patients; the difference between treated and untreated eyes is statistically significant. We believe that these data, together with the favorable safety profile, have the potential to differentiate our XLRP candidate from competitors. Data from three of the seven Group 4 patients were available for analysis at Month 24, including two who were responders at Month 12 (one by the 7 decibel change in at least 5 loci response criteria and the other based on 94
--------------------------------------------------------------------------------

improved retinal sensitivity in the treated eye compared with the untreated eye). These two patients are still responders at Month 24 according to the same criteria; the third patient who has reached Month 24 was not a responder at Month 12 or Month 24. To the best of our knowledge, this is the first XLRP gene therapy clinical trial to demonstrate continued durability of response at this time point. Data from all 28 patients across six dose groups in the Phase 1/2 trial continue to demonstrate a favorable safety profile with no dose-limiting inflammatory responses observed. This safety profile, which has shown no clinically significant inflammation not manageable with steroids, continues to be observed out to 24 months.
We believe that we have a best-in-class XLRP product candidate that may provide significant benefits to patients with XLRP. We expect to:
• present 12-month trial results from the ongoing Phase 1/2 clinical trial
at the
• provide Skyline trial results from the 3-month masked interim analysis in
the first half of calendar year 2022; • provide Skyline trial results from the 12-month data in the fourth
quarter of calendar year 2022; and
• provide Vista trial results from the 6-month masked interim analysis in
the fourth quarter of calendar year 2022.
As part of the Skyline trial, we intend to dose a total of 12 additional patients across two dose groups. The Skyline trial is intended to evaluate the correlation of a new mobility navigation course developed for use with retinitis pigmentosa patients, with the primary endpoint of visual sensitivity at pre-specified loci, providing such data within the earliest timeframe. This trial will have the same overall design as the Vista trial.
ACHM
InJanuary 2021 , we reported results based on a patient-by-patient analysis of data from both ACHMB3 and ACHMA3 trials. For ACHMB3, this consisted of 12-month data from 15 patients, 9-month data from five patients, 6-month data from three patients and 3-month data from three patients for a total of 26 patients across all dose groups. Seven of the 16 patients in the three highest dose groups in the ACHMB3 trial showed improvements in visual sensitivity in the treated area, as measured by static perimetry. No consistent results were seen in the other dose groups. In a subset of these patients with evaluable multi-focal electroretinograms ("ERGs"), improvements in electrical signaling were measurable in the same treated area. For ACHMA3, data analysis consisted of 12-month data from 10 patients, 9-month data from four patients, 6-month data from one patient and 2- or 3-month data from three patients for a total of 18 patients across five dose groups. One additional patient did not have evaluable data. In the 16 patients in the four highest dose groups, three patients showed improvements in visual sensitivity in the treated area, as measured by static perimetry. No consistent results were seen in other dose groups. None of these three patients with improvements in visual sensitivity had evaluable ERGs. InJune 2021 , we announced 12-month data from our on-going Phase 1/2 ACHM clinical trials showing biological activity in patients with mutations in the ACHMB3 gene. InJuly 2021 , we hosted a virtual Research Day that provided an expanded analysis of the 12-month data from our ongoing Phase 1/2 clinical trials in ACHM, including a discussion on light sensitivity and ACHM genetics. These data indicated biologic activity in the dose escalation portions in both the ACHMB3 and ACHMA3 trials. The response was more robust in the ACHMB3 patients than the ACHMA3 patients and, therefore, we plan to move forward with planning for late-stage development of the ACHMB3 product candidate.
Retinal sensitivity, as measured by full-field perimetry, improved in four of 11 ACHMB3 patients in the high dose adult and pediatric groups, as well as two patients in the low dose adult groups. There were no notable
95
--------------------------------------------------------------------------------
Table of Contents
changes in the untreated fellow eyes. The light level in which the patients experienced discomfort, the single most important symptom to patients, also improved in six of the 11 patients with improvement also seen in the fellow eye of those six patients. At our virtual Research Day,Medical College of Wisconsin study investigatorJoseph Carroll , Ph.D., noted that bilateral effects to monocular stimuli are not uncommon in ophthalmology, and he described well-established neuro-anatomical and physiological explanations for this observation. Three of these patients were also responders for visual sensitivity providing more evidence of overall improvement in visual function. Given the evidence of treatment response described above for all adults and the lowest dose group 4 pediatric patients, as well as supportive anecdotal patient reports, we are preparing for an End of Phase 2 (EOP2) submission for our ACHMB3 program and to request a meeting with the FDA in advance of initiating a Phase 2/3 trial. We expect this meeting to occur in the first half of calendar year 2022. We are also collecting novel measures of efficacy including color brightness (CoBri) testing and functional magnetic resonance imaging (fMRI) testing for the recently enrolled and currently enrolling pediatric patients. These additional tests may further support the patient anecdotal reports and the existing evidence of biologic activity of the CNGB3 candidate. For CNGA3, we are focused on analysis of the data from pediatric patients in the Phase 1/2 trial. Preclinical animal data showed a treatment effect in young sheep, which might predict comparable treatment responses in younger pediatric Phase 1/2 patients despite the CNGA3 genetic considerations described above. We recently enrolled six pediatric ACHMB3 patients and five pediatric ACHMA3 patients in higher dose groups 5a and 6a. Three new serious adverse events (SAEs) of significant inflammation that are considered a Suspected Unexpected Serious Adverse Reaction, or SUSAR, occurred in pediatric patients at the highest trial dose concentration (3.2e12 vg/mL); two patients are in the CNGA3 trial, the other is in the CNGB3 trial. An additional CNGB3 pediatric patient at this dose also has presented with significant inflammation during approximately the same post-operative time frame but has not required a subsequent procedure. To address the above safety events in pediatric patients, systemic and local steroid doses have been increased and patients are being monitored closely. No comparable inflammation has been seen in the six pediatric patients across both trials at dose group 5a, nor in any of the adult patients or lowest group 4 pediatric patients on which we previously reported. These new data do not change our plans to continue development of the ACHM product candidates and, as a result, we plan to release 3-month data for high dose pediatric patients, both ACHMB3 and ACHMA3, in the fourth quarter of calendar year 2021. We are currently postponing enrollment of the last pediatric patient in the ACHMA3 trial pending review of longer-term data for the high dose pediatric patients.
Build-To-Suit Manufacturing and Quality Control Facility in
InMay 2021 , we signed a 20-year lease for a build-to-suit 21,250 square foot current Good Manufacturing Practices ("cGMP") manufacturing and quality control facility adjacent to our existingFlorida facility to prepare for late-stage development of our XLRP and ACHM programs. Leasing this cGMP facility is part of our strategy to enable more rapid filing of a Biologics Licensing Application and commercial launch of our XLRP candidate upon potential FDA approval. The cGMP facility is also expected to support more rapid advancement of our product pipeline while providing supply chain redundancy and reducing manufacturing risk. We anticipate that the build-out of the new manufacturing and quality control facility will be completed during the second half of calendar year 2022.
Additional information regarding our new cGMP manufacturing and quality control facility can be found in Note 3 to our financial statements in this Annual Report on Form 10-K.
Underwritten Public Offering

--------------------------------------------------------------------------------
Table of Contents
price of each share of common stock and accompanying warrant was$4.45 , generating gross proceeds of$74.5 million , before deducting underwriting discounts, commissions and other offering expenses payable by us, which totaled$5.2 million . The warrants have an exercise price of$6.00 per share (subject to certain adjustments), are immediately exercisable and expire onFebruary 1, 2026 . We intend to use the net proceeds from the offering, together with other available funds, to fund our ongoing Skyline and Vista trials and our ongoing Phase 1/2 clinical trials in our ACHMB3 and ACHMA3 programs, and for working capital and other general corporate purposes.
At-The-Market Offering Program
OnApril 2, 2021 , we entered into a Controlled Equity OfferingSM Sales Agreement withCantor Fitzgerald & Co. as sales agent to sell shares of our common stock, from time to time, through an "at-the-market offering" program having an aggregate offering price of up to$50.0 million . However, we have not sold any shares under this agreement and are not obligated to do so in the future.
Long-Term Debt Agreement
EffectiveMay 13, 2021 , our long-term loan agreement was amended (the "Amendment") whereby, among other things: (i) a term loan advance of$10.0 million was authorized by the lenders and advanced to us on such date; (ii) the period that we will make interest-only payments on outstanding borrowings was extended toMarch 31, 2022 ; and (iii) the maturity date of the facility was extended fromDecember 1, 2023 toApril 1, 2024 . Subject to certain conditions provided in the Amendment, the interest-only period and the maturity date can be further extended. Subject to the lenders' investment committee's sole discretion, we have the right to request that the lenders make additional term loan advances in an aggregate principal amount of up to$5.0 million . However, there can be no assurances that any term loan advances will be funded by the lenders in the future. Additional information regarding our long-term loan agreement and the Amendment can be found in Note 8 to our financial statements in this Annual Report on Form 10-K. Strategic Collaborations Bionic Sight DuringFebruary 2017 , we entered into a strategic research and development collaboration agreement with Bionic Sight to develop therapies for patients with visual deficits and blindness due to retinal disease. Through the AGTC-Bionic Sight collaboration, the companies seek to develop a new optogenetic therapy that leverages AGTC's deep experience in gene therapy and ophthalmology and Bionic Sight's innovative neuro-prosthetic device and algorithm for retinal coding. The collaboration agreement grants to us, subject to achievement by Bionic Sight of certain development milestones, an option to exclusively negotiate for a limited period of time to acquire: (i) a majority equity interest in Bionic Sight; (ii) the Bionic Sight assets to which the collaboration agreement relates; or (iii) an exclusive license with respect to the product to which the collaboration agreement relates. InMarch 2021 , Bionic Sight, which has responsibility for conducting the clinical trial, reported promising results in its first two cohorts of patients. Bionic Sight reported that these patients, all of whom have complete or near-complete blindness, can now see light and motion, and, in two cases, can detect the direction of motion. The product appears to be safe and well tolerated and Bionic Sight is continuing to enroll patients at higher doses.
Otonomy
DuringOctober 2019 , we entered into a strategic collaboration agreement with Otonomy to co-develop and co-commercialize an adeno-associated virus-based gene therapy to restore hearing in patients with sensorineural 97
--------------------------------------------------------------------------------
Table of Contents
hearing loss caused by a mutation in the gap junction protein beta 2 gene ("GJB2") - the most common cause of congenital hearing loss. Mutations in GJB2 account for approximately 30% of all genetic hearing loss cases. Patients with this mutation can have severe-to-profound deafness in both ears that is identified in screening tests routinely performed in newborns. Under the collaboration agreement, the parties began equally sharing the program costs and proceeds inJanuary 2020 and can include additional genetic hearing loss targets in the future. We and Otonomy announced promising preclinical data at theAmerican Society of Gene andCell Therapy meeting inMay 2021 , demonstrating the rescue of hearing loss and cochlear morphology in two independent mouse models. Collectively, we are conducting IND (investigational new drug)-enabling activities based on pre-IND meeting feedback from the FDA, with an IND filing anticipated in the first half of calendar year 2023.
Additional information regarding the Bionic Sight and Otonomy collaborative agreements can be found in Note 9 to our financial statements in this Annual Report on Form 10-K.
Financial Operations Review Revenue We generate revenue primarily through: (i) collaboration agreements; (ii) sponsored research arrangements with nonprofit organizations for the development and commercialization of product candidates; (iii) federal research and development grant programs; and (iv) licensing arrangements. In the future, we may generate revenue from product sales (if any products are approved), license fees, milestone payments, development services, research and development grants, or from collaboration and royalty payments for the sales of products developed under licenses of our intellectual property. We expect that any revenue we generate will fluctuate from quarter to quarter as a result of the timing and amount of license fees, research and development programs, manufacturing efforts and reimbursements, collaboration milestone payments, and the sale of our products, to the extent that any are approved and successfully commercialized. We do not expect to generate revenue from product sales for the foreseeable future, if at all. If we or our collaborators fail to complete the development of our product candidates in a timely manner or obtain regulatory approval for them, our ability to generate future revenue and our results of operations, financial position and cash flows would be materially adversely affected.
Research and development expenses
Research and development expenses consist primarily of costs incurred for the development of our product candidates and include:
• employee-related expenses, including salaries, benefits, travel and share-based compensation expense; • expenses incurred under agreements with academic research centers, contract research organizations, or CROs, and investigative sites that conduct our clinical trials; • license and sublicense fees and collaboration expenses; • the cost of acquiring, developing and manufacturing clinical trial materials; and
• facilities, depreciation and other expenses, which include direct and
allocated expenses for rent and maintenance of facilities, insurance and
other supplies.
Research and development costs are expensed as incurred. Costs for certain development activities are recognized based on an evaluation of the progress toward completion of specific tasks, using information and data provided to us by our vendors and our clinical sites.
We cannot determine with certainty the duration and completion costs of the current or future clinical trials of our product candidates or if, when, or to what extent we will generate revenue from the commercialization and
98
--------------------------------------------------------------------------------
Table of Contents
sale of any of our product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates. The duration, costs and timing of clinical trials and development of our product candidates will depend on a variety of factors, including: • the scope, rate of progress and expense of our ongoing clinical trials, as well as any additional clinical trials that we are required to, or
decide to, initiate and other research and development activities;
• the timing and level of activity as determined by us or jointly with our partners; • the level of funding, if any, received from our partners; • whether or not we elect to cost share with our collaborators; • the countries in which trials are conducted; • future clinical trial results; • uncertainties in clinical trial enrollment rates or drop-out or discontinuation rates of patients;
• potential additional safety monitoring or other studies requested by
regulatory agencies or elected as best practice by us;
• increased cost and delay associated with manufacturing or testing issues,
including ongoing quality assurance, qualifying new vendors and
developing in-house capabilities through, among other things, our lease
of a new cGMP build-to-suitmanufacturing and quality control facility;
• significant and changing government regulation; and • the timing and receipt of any regulatory approvals. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate or if we experience significant delays in enrollment in or execution of any of our clinical trials, which could be adversely impacted by the COVID-19 pandemic, we could be required to expend significant additional financial resources and time on the completion of clinical development. From our inception and throughJune 30, 2021 , we have incurred approximately$282.6 million in research and development expenses. We expect our research and development expenses to increase for the foreseeable future as we continue the development of our product candidates, explore potential applications of our gene therapy platform in other indications and execute our plan to open and operate a leased cGMP manufacturing and quality control facility.
General and administrative and other expenses
General and administrative and other expenses primarily consist of salaries and related costs for personnel, including share-based compensation and travel expenses for our employees in executive, operational, legal, business development, finance and human resource functions. Other general and administrative expenses include costs to support employee training and development, board of directors' costs, depreciation, insurance, facility-related costs not otherwise included in research and development expenses, professional fees for legal services, including patent-related expenses, and accounting, investor relations, corporate communications and information technology services. We anticipate that our general and administrative and other expenses will continue to increase in the future as we hire additional employees to support our research and development efforts, collaboration arrangements, and the potential commercialization of our product candidates. Additionally, if and when we believe that regulatory approval of our first product candidate appears likely, we anticipate an increase in payroll and related expenses as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of our product candidates. Our general and administrative expenses are also expected to increase as we execute our plan to open and operate a leased cGMP manufacturing and quality control facility. 99

Investment income, net
Investment income, net consists of interest earned on cash and cash equivalents and held-to-maturity investments in debt securities. During the year endedJune 30, 2021 , investment income, net declined by$1.1 million when compared to the prior year. Such reduction in investment income, net was primarily due to lower interest rates in the marketplace.
Interest expense
Interest expense during the year endedJune 30, 2021 was primarily attributable to the loan agreement that we entered into onJune 30, 2020 and amended inMay 2021 . Additional information regarding our long-term loan agreement can be found in Note 8 to our financial statements in this Annual Report on Form 10-K.
Provision for (benefit from) income taxes
Income tax benefit for the year endedJune 30, 2021 was$2.1 million compared to income tax expense of$83,000 for the year endedJune 30, 2020 . The income tax benefit during the year endedJune 30, 2021 was primarily due to the reversal of our uncertain tax position liabilities, including the related interest and penalties. During the year endedJune 30, 2020 , income tax expense was primarily due to estimated interest and penalties on our then-existing uncertain tax positions. Additional information regarding our income taxes can be found in Note 11 to our financial statements in this Annual Report on Form 10-K.
Critical Accounting Policies and Estimates
Management's Discussion and Analysis of Financial Condition and Results of Operations included in this Annual Report on Form 10-K is based on our financial statements, which have been prepared in accordance withU.S. generally accepted accounting principles ("U.S. GAAP"). The preparation of those financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, judgments and methodologies, including those related to accrued expenses and share-based compensation. We base our estimates on historical experience, current conditions, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from our estimates under different assumptions or conditions. Moreover, we may need to change the assumptions underlying our estimates due to risks and uncertainties related to the COVID-19 pandemic or otherwise and those changes could have a material adverse effect on our statements of operations, financial condition and cash flows. While our significant accounting policies are described in Note 2 to our financial statements in this Annual Report on Form 10-K, we believe that the following accounting policies are most critical to the preparation of our financial statements.
Revenue recognition
We recognize revenue when our customer obtains control of promised goods or services, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. To determine the appropriate amount of revenue to be recognized for arrangements determined to be within the scope of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, we perform the following five steps: (i) identification of the contract; (ii) determination of whether the promised goods or services are performance obligations; (iii) measurement of the transaction price, including any constraints on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) we satisfy each performance obligation. We only apply the five-step model to contracts if it is probable that we will collect consideration that we are entitled to in exchange for the goods or services we transfer to the customer. 100
--------------------------------------------------------------------------------
Table of Contents
Performance obligations are promises to transfer distinct goods or services to a customer. Promised goods or services are considered distinct when (i) the customer can benefit from the good or service on its own or together with other readily available resources and (ii) the promised good or service is separately identifiable from other promises in the contract. When assessing whether promised goods or services are distinct, we consider factors such as the stage of development of the underlying intellectual property, the capabilities of a customer to develop the intellectual property on its own or whether the required expertise is readily available. We estimate the transaction price based on the amount expected to be received for transferring the promised goods or services in the contract. The consideration may include both fixed consideration and variable consideration. At the inception of an arrangement that includes variable consideration and at the end of each reporting period, we evaluate the amount of potential customer payments and the likelihood that such payments will be received. We utilize either the most likely amount method or the expected amount method to estimate the amount to be received based on which method better predicts the amount expected to be received. If it is probable that a significant revenue reversal would not occur, the variable consideration is included in the transaction price. We will assess our revenue generating arrangements to determine whether a significant financing component exists and conclude that a significant financing component does not exist in an arrangement if the: (a) promised consideration approximates the cash selling price of the promised goods and services or any significant difference is due to factors other than financing; and (b) timing of payment approximates the transfer of goods and services and performance is over a relatively short period of time within the context of the entire term of the contract. Our contracts often include development and regulatory milestone payments. At contract inception, we evaluate whether any such milestones are considered probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or the customer's control, such as regulatory approvals, are not included in the transaction price. At the end of each subsequent reporting period, we reevaluate the probability of achievement of such development milestones and any related constraint and, if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect collaboration revenue and earnings in the period of adjustment. For arrangements that may include sales-based royalties, including milestone payments based on the level of sales, and the license is deemed to be the predominant item to which the royalties relate, we recognize revenue at the later of (i) when the related sale occurs or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, we have not recognized any royalty revenue resulting from any of our collaboration arrangements. We allocate the transaction price based on the estimated stand-alone selling price of the underlying performance obligation or, in the case of certain variable consideration, to one or more performance obligations. We use assumptions that require judgment to determine the stand-alone selling price for each performance obligation identified in a contract. We utilize key assumptions to determine the stand-alone selling price, which may include other comparable transactions, pricing considered in negotiating the transaction and the estimated costs to complete the related performance obligation. Certain variable consideration is allocated specifically to one or more performance obligation in a contract when the terms of the variable consideration relate to the satisfaction of a performance obligation and the resulting amounts allocated to each performance obligation are consistent with the amounts we would expect to receive for each performance obligation. For performance obligations consisting of licenses and other promises, we use judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from upfront fees. We evaluate the measure of progress each reporting period and, if necessary, adjust the measure of performance and related revenue recognition. If the license to our intellectual 101

property is determined to be distinct from the other performance obligations identified in the arrangement, we will recognize revenue from upfront fees allocated to the license when the license is transferred to the customer and the customer is able to use and benefit from the license. We receive payments from our customers based on billing terms established in each contract. Such billings generally have 30-day payment terms. Upfront payments and fees are recorded as deferred revenue upon receipt or when due until we perform our obligations under those arrangements. Amounts are recorded as accounts receivable when the right to consideration is unconditional.
Research and development expenses
Research and development expenses include costs incurred in identifying, developing and testing product candidates and generally comprise compensation and related benefits and non-cash share-based compensation to research-related employees; laboratory costs; animal and laboratory maintenance and supplies; rent; utilities; clinical and preclinical expenses; and payments for sponsored research, scientific and regulatory consulting fees and testing. As part of the process of preparing our financial statements, estimates of accrued expenses are necessary. The estimation process involves reviewing quotations and contracts, identifying services that have been performed on our behalf, and determining the level of services performed and associated costs incurred for services for which we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice monthly in arrears for services performed or when contractual milestones are met. We estimate our accrued expenses at the end of each reporting period based on the facts and circumstances known at that time. The significant estimates in our accrued research and development expenses primarily relate to expenses incurred with respect to academic research centers, contract research organizations and other vendors in connection with research and development activities for which we have not yet been invoiced. There are instances where our service providers require advance payments at the inception of a contract and other circumstances where our payments to a vendor will exceed the level of services provided, in both cases resulting in a prepayment of research and development expenses. Such prepayments are charged to research and development expense as and when the service is provided or when a specific milestone outlined in the contract is reached.
Share-based compensation
We account for share-based awards issued to employees in accordance with Accounting Standards Codification Topic 718, Compensation-Stock Compensation, and generally recognize share-based compensation expense on a straight-line basis over the period that an employee is required to provide service in exchange for the award. In certain instances, we use a graded vesting schedule to recognize compensation expense. We also award stock options and restricted stock units to nonemployees in exchange for consulting services. The determination of share-based compensation costs for nonemployees is generally consistent with that of employee awards, with expense recognized as services are provided to us over the related service period. For purposes of calculating share-based compensation expense, we estimate the fair value of stock options using a Black-Scholes option-pricing model. The determination of the fair value of a share-based compensation award utilizing the Black-Scholes model is affected by our stock price and a number of assumptions, including the expected volatility of our stock, the expected life of the stock option, the risk-free interest rate and expected dividends. Additionally, we use a Monte Carlo simulation model to determine the fair value of restricted stock units with market-based vesting conditions for purposes of calculating share-based compensation expense. The Monte Carlo simulation model incorporates the probability of satisfying a market condition and uses transaction details such as our stock price, contractual terms, maturity and risk-free interest rates, as well as volatility. The fair value of restricted stock units with no performance or market vesting conditions is based on the market value of our common stock on the date of grant. 102

If factors change and we employ different assumptions, share-based compensation expense may differ significantly from what we have recorded in the past. If there is a difference between the assumptions used in determining share-based compensation expense and the actual factors that become known over time, specifically with respect to anticipated forfeitures, we may change the input factors used in determining share-based compensation costs for future awards. These changes, if any, may materially impact our results of operations in the period that such changes are made.
Income taxes
We use the asset and liability method to account for income taxes. Under this method, deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases. Deferred tax assets and liabilities are measured using enacted rates expected to apply to taxable income in the years in which those temporary differences are projected to be recovered or settled. As required byU.S. GAAP, we recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. Interest and penalties related to uncertain tax positions are reflected in the provision for (benefit from) income taxes.

We do not allocate employee-related costs, including share-based compensation, costs associated with broad technology platform improvements or other indirect costs, to specific programs, as they are deployed across multiple projects under development and, as such, are separately classified as internal research and development expenses in the table above. Research and development expenses for the years endedJune 30, 2021 and 2020 were$44.4 million and$35.8 million , respectively, an increase of$8.6 million , or 24%. Such increase was primarily attributable to: •$8.8 million of increased external spending for our XLRP trials due to
our planned manufacturing, clinical site preparation and other activities
related to our Skyline and Vista trials; •$1.0 million of increased external spending for our research and discovery programs, which was primarily due to planned material
production costs in connection with our CNS preclinical program targeting
FTD; and
•
expenses for temporary staffing and consultants while we recruit new
employees, partially offset by a reduction in laboratory supply costs due
to the timing of our needs.
Such increases were partially offset by: (i) a$1.2 million decrease in external spending for our ACHM trials; (ii) a$0.4 million decrease in expenses in connection with the wind-down of our X-linked retinoschisis, or XLRS, program; and (iii) a$0.3 million decrease in our share-based compensation expense. The decrease in ACHM expenses was primarily due to reduced patient enrollment, patient visits and new site activations during the year endedJune 30, 2021 when compared to the prior year, all of which reduce our overall clinical programs costs, partially offset by incremental expenses for our mobile vision center. The decline in share-based compensation expense was due to, among other things, the cost attributable to a performance-based stock option award that achieved a milestone during the year endedJune 30, 2020 with no corresponding current year activity. 104

Such increase was primarily due to higher (i) legal fees resulting from increased reliance on external legal counsel and (ii) recurring operating and business development costs pertaining to normal operations. Such increases were partially offset by a reduction in employee-related costs of$0.4 million that resulted from a lower corporate headcount during the year endedJune 30, 2021 when compared to the prior year.
Liquidity and Capital Resources
We have incurred cumulative losses and negative cash flows from operations since our inception and, as ofJune 30, 2021 , we had an accumulated deficit of$239.3 million . It will be several years, if ever, before we have a product candidate ready for commercialization. We expect that our research and development expenses and general and administrative and other expenses will continue to increase and, as a result, we anticipate that we will require additional capital to fund our operations, which we may raise through a combination of equity offerings, debt financings, other third-party funding, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. Most recently, we received: (i)$34.8 million of proceeds from the issuance of our common stock, net of issuance costs, inFebruary 2020 ; (ii)$9.9 million of loan proceeds, net of debt discounts, during each ofJune 2020 andMay 2021 ; and (iii) net proceeds of$69.3 million inFebruary 2021 from the underwritten public offering that is described above under "Recent Developments." Among other things, theMay 2021 net cash proceeds are expected to partially fund certain equipment and shared building fit out costs, as well as new employee hires, in connection with our lease and operation of a new cGMP build-to-suit manufacturing and quality control facility inAlachua, Florida . Importantly, through a tenant improvement allowance and tiered rental rates, we have structured our third-party leasing costs for such facility in a way that will not significantly impact our cash runway until the fiscal year endingJune 30, 2024 . Additional information regarding the new manufacturing and quality control facility and our long-term loan agreement can be found in Notes 3 and 8, respectively, to our financial statements in this Annual Report on Form 10-K. We are closely monitoring ongoing developments in connection with the COVID-19 pandemic, which may negatively impact our projected cash position and access to capital. We will continue to assess our cash position and, if circumstances warrant, make appropriate adjustments to our operating plan. Cash in excess of immediate requirements is invested in accordance with our investment policy, which primarily seeks to maintain adequate liquidity and preserve capital by generally limiting investments to certificates of deposit and investment-grade debt securities that mature within twelve months. As ofJune 30, 2021 , our cash and cash equivalents were held in bank accounts and money market funds, while our investments consisted of aU.S. Treasury security that matured inJuly 2021 , consistent with our investment policy. 105

Specifically, the cash used in operating activities of$51.2 million during the year endedJune 30, 2021 was due to a net loss of$57.8 million , partially offset by non-cash items in our statement of operations of$2.8 million and favorable changes in our operating assets and liabilities of$3.9 million . The cash used in operating activities of$41.6 million during the year endedJune 30, 2020 was due to a net loss of$45.9 million , partially offset by non-cash items in our statement of operations of$2.2 million and favorable changes in our operating assets and liabilities of$2.1 million . Investing activities. Cash provided by investing activities of$38.1 million during the year endedJune 30, 2021 consisted primarily of cash proceeds of$61.0 million from maturities of investments, net of investment purchases of$21.0 million , partially offset by purchases of property and equipment of$1.5 million and intellectual property costs of$0.4 million . Cash provided by investing activities of$8.4 million during the year endedJune 30, 2020 consisted primarily of cash proceeds of$72.5 million from maturities of investments, net of investment purchases of$58.9 million , partially offset by an equity investment in Bionic Sight of$4.0 million , purchases of property and equipment of$0.9 million and intellectual property costs of$0.3 million .

These items were partially offset by (i) payments for deferred financing fees and taxes related to equity awards and (ii) principal payments on a finance lease. Cash provided by financing activities of$45.0 million during the year endedJune 30, 2020 primarily consisted of: (i) proceeds of$34.8 million from the issuance of common stock, net of issuance costs; (ii) net cash received of$9.9 million from our collateralized debt arrangement that closed onJune 30, 2020 ; and (iii) proceeds from exercises of common stock options of$0.4 million . These items were partially offset by principal payments on a finance lease.
Operating capital requirements
To date, we have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate significant revenue from product sales unless and until we obtain regulatory approval of and commercialize one of our current or future product candidates. We anticipate that we will continue to generate losses for the foreseeable future as we continue the development of, and seek regulatory approvals for, our product candidates, and begin to commercialize any approved products. We are subject to all of the risks incident in the development of new gene therapy products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business.
We believe that our available cash and cash equivalents and investments, which

fund currently planned research and discovery programs into calendar year 2023. However, we will require substantial additional funding to: (i) finish our Vista trial; (ii) move our ACHMB3 product candidate forward; (iii) complete the process necessary to seek regulatory approval for our lead product candidates; (iv) build the sales, marketing and distribution infrastructure that we believe will be necessary to commercialize our lead product candidates, if approved; and (v) execute our plan to open and operate a leased cGMP manufacturing and quality control facility.
