The following discussion and analysis of our financial condition and results of
operations should be read in conjunction with our financial statements and the
related notes to those statements included elsewhere in this Annual Report on
Form 10-K. In addition to historical financial information, the following
discussion and analysis contains forward-looking statements that involve risks,
uncertainties and assumptions. Our actual results and timing of selected events
may differ materially from those anticipated in these forward-looking statements
as a result of many factors, including those discussed in Part I, Item 1A, "Risk
Factors" and elsewhere in this Annual Report on Form 10-
Overview
We are a clinical-stage biopharmaceutical company focused on discovering, developing and commercializing antiviral therapeutics to improve the lives of patients suffering from difficult to treat, life-threatening viral infections. Our current focus is on the development of product candidates to treat COVID-19, hepatitis C virus ("HCV"), dengue and respiratory syncytial virus ("RSV").
COVID 19 - Bemnifosubvir Combination Regimen
Our most advanced product candidate for the treatment of COVID-19 is bemnifosbuvir, an investigational, novel, orally administered guanosine nucleotide analog polymerase inhibitor which we believe could be a preferred backbone for an oral combination regimen. Bemnifosbuvir has a unique dual mechanism of action at both the RNA-dependent RNA polymerase (RdRp) and NiRAN active sites on the highly conserved SARS-CoV-2 RNA polymerase. As we anticipate continued rapid emergence and evolution of viral variants together with the potential for viral drug resistance to single agent therapies which could render previously effective monotherapy obsolete, we have prioritized the development of bemnifosbuvir as combination therapy for the treatment of COVID-19.
We do not know whether this combination of bemnifosbuvir with a protease inhibitor will produce a synergistic benefit or otherwise lead to positive outcomes for the patients we are seeking to treat. We have not yet developed a protease inhibitor to evaluate in combination with bemnifosbuvir. Although we have begun efforts to discover a protease inhibitor utilizing our internal discovery capabilities, these efforts are at a very early stage and we do not know if such efforts will be successful, or if successful, when a protease inhibitor product candidate generated from our discovery efforts would be allowed to enter clinical trials. Alternatively, we may in-license or acquire the rights to develop and commercialize a protease inhibitor drug candidate from a third party.
HCV - Bemnifosbuvir in combination with ruzasvir
For the treatment of chronic HCV infection, we are advancing a novel combination
of bemnifosbuvir and ruzasvir, an investigational nonstructural protein 5A
("NS5A") inhibitor that we exclusively in-licensed from Merck in
Dengue - AT-752
Dengue is a mosquito-borne viral infection that infects up to 400 million people
worldwide a year, causing substantial public health and economic
burden. Currently there are no antiviral therapies approved by either the

COVID 19 Update
While we believe there is currently an urgent need for treatments for COVID-19, the longevity and extent of the ongoing COVID-19 pandemic is uncertain and it is unclear whether SARS-CoV-2 will become an endemic human coronavirus that may circulate in the human population after the current pandemic has subsided. If the pandemic were to dissipate and the endemic does not result, whether due to a significant decrease in new infections, the effectiveness of vaccines, the effectiveness of other treatment options, or otherwise, the need for treatments could decrease significantly. If the need for a treatment decreases before or soon after commercialization of a bemnifosbuvir COV19 combination, if successfully developed and approved, our business could be adversely impacted.
Financial Operations Overview
As of
We do not have any products approved for sale and have not generated any product revenue since inception. We do not anticipate generating any revenue from product sales for the foreseeable future. Our ability to generate product revenue will depend on the successful development, regulatory approval and eventual commercialization of one or more of our product candidates. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through private or public equity or debt financings, collaborative or other arrangements with corporate sources, or through
125
--------------------------------------------------------------------------------
other sources of financing. Adequate funding may not be available to us on acceptable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we may have to significantly delay, scale back or discontinue the development and commercialization of our product candidates.
We plan to continue to use third-party service providers, including contract research organizations ("CROs") and contract manufacturing organizations ("CMOs"), to carry out our preclinical and clinical development and to manufacture and supply the materials to be used during the development and commercialization of our product candidates.
We expect to continue to incur significantly higher expenses over the next several years. We anticipate that our expenses will increase significantly in connection with our ongoing activities, as we: • continue clinical development of bemnifosbuvir for the treatment of COVID-19;
• continue clinical development of AT-752 for the treatment of dengue;
• initiate clinical development of bemnifosbuvir and ruzasvir for the treatment
of HCV;
• continue IND-enabling activities and commence clinical development activities
for product candidates for the treatment of RSV;
• maintain, expand, protect and enforce our intellectual property portfolio;
• hire additional research, development and general and administrative
personnel;
• establish commercialization capabilities; and
• incur additional costs as we continue to operate as a public company,
particularly now that we are a large accelerated filer as of
2021.

We do not have any products approved for sale and to date, we have not generated any revenue from product sales.
Our revenue has been collaboration revenue solely derived from the Roche License

Operating Expenses
Research and Development Expenses
Substantially all of our research and development expenses consist of expenses incurred in connection with the development of our product candidates. These expenses include fees paid to third parties to conduct certain research and development activities on our behalf, consulting costs, certain payroll and personnel-related expenses, including salaries and bonuses, employee benefit costs and stock-based compensation expenses for our research and product development employees and allocated overhead, including rent, equipment, depreciation, information technology costs and utilities attributable to research and development personnel. We expense both internal and external research and development expenses as they are incurred. In circumstances where amounts have been paid in advance or in excess of costs incurred, we record a prepaid expense, which is expensed as services are performed or goods are delivered.
A significant portion of our research and development costs have been external costs, which we track by therapeutic area. Our internal research and development costs are primarily personnel-related costs, facility costs, including depreciation. We have not historically tracked our internal research and development expenses by therapeutic area as they are deployed across multiple programs.

Internal research and development costs 34,900 9,855 2,186
Total research and development expenses
We are focusing substantially all of our resources on the development of our product candidates, particularly bemnifosbuvir. We expect our research and development expenses to increase substantially for at least the next few years, as we seek to initiate additional clinical trials for our product candidates, complete our clinical programs, pursue regulatory approval of our product candidates and prepare for the possible commercialization of these product candidates. Predicting the timing or cost to complete our clinical programs or validation of our commercial manufacturing and supply processes is difficult and delays may occur because of many factors, including factors outside of our control. For example, if the FDA or other regulatory authorities were to require us to conduct clinical trials beyond those that we currently anticipate, we could be required to expend significant additional financial resources and time on the completion of clinical development. Furthermore, we are unable to predict when or if our product candidates will receive regulatory approval with any certainty.
General and Administrative Expenses
General and administrative expenses consist principally of payroll and personnel expenses, including salaries and bonuses, benefits and stock-based compensation expenses, professional fees for legal, consulting, accounting and tax services, allocated overhead, including rent, equipment, depreciation, information technology costs and utilities, and other general operating expenses not otherwise classified as research and development expenses.
We anticipate that our general and administrative expenses may increase as a
result of increased personnel costs, expanded infrastructure and higher
consulting, legal and accounting services costs associated with complying with

As of
Future Funding Requirements
To date, we have not generated any product revenue. We do not expect to generate
any product revenue unless and until we obtain regulatory approval for and
commercialize any of our product candidates and we do not know when, or if, this
will occur. We expect that our net cash used in operating activities will
increase significantly as we advance our product candidates through preclinical
and clinical development, seek regulatory approval, and prepare for and, if
approved, proceed to commercialization; acquire, discover, validate and develop
additional product candidates; obtain, maintain, protect and enforce our
intellectual property portfolio; and hire additional personnel. We are subject
to all of the risks typically related to the development of new product
candidates, and we may encounter unforeseen expenses, difficulties,
complications, delays and other unknown factors that may adversely affect our
business. Moreover, we expect to incur additional general and administrative
costs as we continue to operate as a public company, particularly now that we
are a large accelerated filer as of
We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable future. We may seek to raise capital through public or private equity or debt financings, collaborative or other arrangements with corporate sources, or through other sources of financing. We anticipate that we may need to raise substantial additional capital, the requirements for which will depend on many factors, including: • the scope, timing, rate of progress and costs of our drug discovery efforts,
preclinical development activities, laboratory testing and clinical trials for
our product candidates;
• the number and scope of clinical programs we decide to pursue;
• the cost, timing and outcome of preparing for and undergoing regulatory review
of our product candidates;
• the scope and costs of development and commercial manufacturing activities;
• the cost and timing associated with commercializing our product candidates, if
they receive marketing approval;
• the extent to which we acquire or in-license other product candidates and
technologies;
• the costs of preparing, filing and prosecuting patent applications,
maintaining and enforcing our intellectual property rights and defending
intellectual property-related claims;
• our ability to establish and maintain collaborations on favorable terms, if at
all;
• our efforts to enhance operational systems and our ability to attract, hire
and retain qualified personnel, including personnel to support the development of our product candidates and, ultimately, the sale of our products, following regulatory approval;
• our implementation of operational, financial and management systems; and
• the costs associated with being a public company.
A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we will continue to require additional capital to meet operational needs and capital requirements associated with such operating plans. If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends,
130
--------------------------------------------------------------------------------
repurchase our common stock, make certain investments or engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders.
Adequate funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. If we are unable to raise additional funds when needed, we may be required to delay, reduce, or terminate some or all of our development programs and clinical trials or we may also be required to sell or license to others rights to our product candidates in certain territories or indications that we would prefer to develop and commercialize ourselves. If we are required to enter into collaborations and other arrangements to supplement our funds, we may have to give up certain rights that limit our ability to develop and commercialize our product candidates or may have other terms that are not favorable to us or our stockholders, which could materially affect our business and financial condition.

We enter into contracts in the normal course of business with third-party contract organizations for preclinical and clinical studies and testing, manufacture and supply of our preclinical materials and other services and products used for operating purposes. These contracts do not contain any minimum purchase commitments and generally provide for termination following a certain period after notice, and therefore we believe that our non-cancelable obligations under these agreements are not material. Payments due upon cancelation consist only of payments for services provided and expenses incurred up to the date of cancelation.

Critical Accounting Policies and Estimates
Our financial statements have been prepared in accordance with
Our critical accounting policies are those policies that require the most significant judgements and estimates in the preparation of the financial statements. Management has determined that our most critical accounting policies are those relating to revenue recognition, accrued research and development expenses and stock based compensation.
Revenue Recognition
As of
We analyze our collaboration arrangements to assess whether they are within the scope of Accounting Standards Codification ASC Topic 808, Collaborative Arrangements ("ASC 808"), to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards that are dependent on the commercial success of such activities. If we conclude that some or all aspects of the arrangement are within the scope of ASC 808 and do not represent a transaction with a customer, we recognize our allocation of the shared costs incurred with respect to the jointly conducted activities as a component of the related expense in the period incurred. If we conclude that some or all aspects of the arrangement represent a transaction with a customer, we account for those aspects of the arrangement within the scope of ASC 606, Revenue from Contracts with Customers ("ASC 606").
To determine the appropriate amount of revenue to be recognized for arrangements that we determine are within the scope of ASC 606, we perform the following steps: (i) identify the contract(s) with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) each performance obligation is satisfied. ASC 606 requires significant judgment and estimates and results in changes to, but not limited to: (i) the determination of the transaction price, including estimates of variable consideration, (ii) the allocation of the transaction price, including the determination of estimated selling price, and (iii) the pattern of recognition, including the application of proportional performance as a measure of progress on service-related promises and application of point-in-time recognition for supply-related promises.
The transaction price is generally comprised of an upfront payment due at contract inception and variable consideration in the form of payments for our services and materials and milestone payments due upon the achievement of specified events. Other payments we could be entitled to include tiered royalties earned when customers recognize net sales of licensed products. We consider the existence of any significant financing component within our arrangements and have determined that a significant financing component does not exist in our arrangements as substantive business purposes exist to support the payment structure other than to provide a significant benefit of financing. We measure the transaction price based on the amount of consideration to which we expect to be entitled in exchange for transferring the promised goods and/or services to the customer. We utilize either the expected value method or the
133
--------------------------------------------------------------------------------
most likely amount method to estimate the amount of variable consideration, depending on which method is expected to better predict the amount of consideration to which we will be entitled. Amounts of variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. With respect to arrangements that include payments for a development or regulatory milestone payment, we evaluate whether the associated event is considered probable of achievement and estimate the amount to be included in the transaction price using the most likely amount method. Milestone payments that are not within our control or the licensee, such as those dependent upon receipt of regulatory approval, are not considered to be probable of achievement until the triggering event occurs. At the end of each reporting period, we re-evaluate the probability of achievement of each milestone 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 revenue and net loss in the period of adjustment. For arrangements that include sales-based royalties, including milestone payments based upon the achievement of a certain level of product sales, wherein the license is deemed to be the sole or predominant item to which the payments relate, we recognize revenue upon the later of: (i) when the related sales occur or (ii) when the performance obligation to which some or all of the payment has been allocated has been satisfied (or partially satisfied). Consideration that would be received for optional goods and/or services is excluded from the transaction price at contract inception.
We generally allocate the transaction price to each performance obligation based on a relative standalone selling price basis. We develop assumptions that require judgment to determine the standalone selling price for each performance obligation in consideration of applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating the agreement with the customer and estimated research and development costs. However, in certain instances, we allocate variable consideration entirely to one or more performance obligation if the terms of the variable consideration relate to the satisfaction of the respective performance obligation and the amount allocated is consistent with the amount we would expect to receive for the satisfaction of the respective performance obligation.
We recognize revenue based on the amount of the transaction price that is
allocated to each respective performance obligation when or as the performance
obligation is satisfied by transferring a promised good or service to the
customer. For performance obligations that are satisfied at a point in time, we
recognize revenue when control of the goods and/or services is transferred to
the customer. For performance obligations that are satisfied over time, we
recognize revenue by measuring the progress toward complete satisfaction of the
performance obligation using a single method of measuring progress which depicts
the performance in transferring control of the associated goods and/or services
to the customer. We generally use input methods to measure the progress toward
the complete satisfaction of performance obligations satisfied over time. With
respect to arrangements containing a license to our intellectual property that
is determined to be distinct from the other performance obligations identified
in the arrangement, we recognize revenue from amounts allocated to the license
when the license is transferred to the licensee and the licensee is able to use
and benefit from the license. For licenses that are bundled with other promises,
we utilize 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. Significant management judgment is
required in determining the level of effort and costs required under an
arrangement and the period over which we are expected to complete our
performance obligations under an arrangement. We evaluate the measure of
progress each reporting period and, if necessary, adjust the measure of
performance and related revenue recognition. Any such adjustments are recorded
on a cumulative catch-up basis, which would affect revenue and net loss in the
period of adjustment.

Contract costs
We recognize as an asset the incremental costs of obtaining a contract with a
customer if the costs are expected to be recovered. We have elected a practical
expedient wherein we recognize the incremental costs of obtaining a contract as
an expense when incurred if, at inception, the expected amortization period of
the asset that we otherwise would have recognized is one year or less. In
connection with the Roche License Agreement, we incurred an incremental cost of
We have entered into various agreements with CMOs and CROs. Our research and development accruals are estimated based on the level of services performed, progress of the studies, including the phase or completion of events, and contracted costs. The estimated costs of research and development provided, but not yet invoiced, are included in accrued liabilities on the balance sheet. If the actual timing of the performance of services or the level of effort varies from the original estimates, we will adjust the accrual accordingly. Payments made to CMOs and CROs under these arrangements in advance of the performance of the related services are recorded as prepaid expenses and other current assets until the services are rendered. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period. To date, there have not been any material adjustments to our prior estimates of accrued research and development expenses.
Stock-Based Compensation
We use a fair value-based method to account for all stock-based compensation
arrangements with employees and non-employees, including stock options and stock
awards. The fair value of the option granted is recognized on a straight-line
basis over the period during which an optionee is required to provide services
in exchange for the option award, known as the requisite service period, which
usually is the vesting period. In determining fair value of the stock options
granted, we use the Black-Scholes model, which requires the input of subjective
assumptions. These assumptions include: estimating the fair market value of the
common stock, estimating the length of time employees will retain their vested
stock options before exercising them (expected term), the estimated volatility
of our common stock price over the expected term (expected volatility),
risk-free interest rate and expected dividends. See Note 10 to our audited
consolidated financial statements included elsewhere in this Annual Report on
Form 10-K for information concerning certain of the specific assumptions we used
in applying the Black-Scholes option pricing model to determine the estimated
fair value of our stock options granted during the years ended
Estimating the Fair Value of Common Stock
Prior to our IPO, we were required to estimate the fair value of the common stock underlying our share-based awards when performing the fair value calculations using the Black-Scholes option pricing model. Prior to our IPO, the fair value of the common stock underlying our stock options has been determined on each grant date by our board of directors, with input from management, considering the most recently available third-party valuation of our common shares. All options to purchase shares of our common stock are intended to be granted with an exercise price per share no less than the estimated fair value per share of our common stock underlying those options on the date of grant, based on the information known to us on the date of grant.
In the absence of a public trading market for our common stock prior to our IPO, on each grant date, we developed an estimate of the fair value of our common stock based on valuations from an independent third-party valuation firm using information known to us on the date of grant, a review of any recent events and their potential impact on the estimated fair value per share of the common stock.
135
--------------------------------------------------------------------------------
The third-party valuations of our common stock were determined in accordance
with the guidelines outlined in the
The assumptions used to determine the estimated fair value of our common stock are based on numerous objective and subjective factors, combined with management judgment, including: • external market conditions affecting the pharmaceutical and biotechnology
industry and trends within the industry;
• our stage of development and business strategy;
• the rights, preferences and privileges of our redeemable convertible preferred
stock relative to those of our common stock;
• the prices at which we sold shares of our redeemable convertible preferred
stock;
• our financial condition and operating results, including our levels of
available capital resources;
• the progress of our research and development efforts;
• equity market conditions affecting comparable public companies; and
• general U.S. market conditions and the lack of marketability of our common
stock.
The Practice Aid identifies various available methods for allocating enterprise value across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date. In accordance with the Practice Aid, we considered the following methods: • Option Pricing Method. Under the option pricing method, or OPM, shares are
valued by creating a series of call options with exercise prices based on the liquidation preferences and conversion terms of each equity class. The estimated fair values of the preferred and common stock are inferred by analyzing these options.
• Probability-Weighted Expected Return Method. The probability-weighted expected
return method, or PWERM, is a scenario-based analysis that estimates value per share based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to us, as well as the economic and control rights of each share class.
Based on our early stage of development and other relevant factors, we determined that OPM method as well as a hybrid approach of the OPM and the PWERM methods were the most appropriate methods for allocating our enterprise value to determine the estimated fair value of our common stock. In determining the estimated fair value of our common stock, our board of directors also considered the fact that our stockholders could not freely trade our common stock in the public markets. Accordingly, we applied discounts to reflect the lack of marketability of our common stock based on the weighted-average expected time to liquidity. The estimated fair value of our common stock at each grant date reflected a non-marketability discount partially based on the anticipated likelihood and timing of a future liquidity event.
Upon the completion of our initial public offering, the fair value of our common stock is based on the daily closing quoted market price of our common stock.
We also account for any modifications to share based payments in accordance with ASC Topic 718, Compensation - Stock Compensation (ASC 718).
Indemnification Agreements
We enter into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, including in connection with any trade secret, copyright, patent or other intellectual property infringement claim by any third party with respect to its technology. The term of these indemnification agreements is generally perpetual any time after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these arrangements is not determinable. We have never incurred costs to defend lawsuits or
136
--------------------------------------------------------------------------------
settle claims related to these indemnification agreements. As a result, we believe the fair value of these agreements is minimal.
We have also agreed to indemnify our directors and officers for certain events or occurrences while the director or officer is, or was serving, at our request in such capacity. The indemnification period covers all pertinent events and occurrences during the director's or officer's service. The maximum potential amount of future payments we could be required to make under these indemnification agreements is not specified in the agreements; however, we have director and officer insurance coverage that reduces our exposure and enables us to recover a portion of any future amounts paid. We believe the estimated fair value of these indemnification agreements in excess of applicable insurance coverage is minimal.
