You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report. Some of the information contained in this discussion and analysis or set forth elsewhere, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Annual Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the “Risk Factors” section of this Annual Report to gain an understanding of the important factors that could cause actual results to differ materially from our forward-looking statements. Please also see the section titled “Special Note Regarding Forward-Looking Statements.”

Overview

We are a clinical-stage biopharmaceutical company dedicated to the identification, development and commercialization of differentiated medicines to address the unmet medical needs of patients with cancers. We seek to utilize our team’s deep drug development experience to maximize the potential of our lead development candidate, furmonertinib, and advance a pipeline of novel therapeutics, such as next-generation antibody drug conjugates, through approval and commercialization in patients suffering from cancer, with an initial focus on solid tumors. Furmonertinib is currently being evaluated in multiple clinical trials across a range of EGFRm in NSCLC, including a pivotal Phase 3 clinical trial in treatment naive, or first-line, patients with locally advanced or metastatic EGFRm NSCLC with exon 20 insertion mutations. We received Breakthrough Therapy Designation for furmonertinib for this disease from the FDA in October 2023, and Orphan Drug Designation for treatment of NSCLC with EGFRm or HER2 mutations or HER4 mutations in February 2024. A product candidate can receive Breakthrough Therapy Designation if preliminary clinical evidence indicates that the product candidate, alone or in combination with one or more other drugs, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For drugs that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor can help to identify the most efficient path for development. The receipt of a Breakthrough Therapy Designation for a product candidate may not result in a faster

development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and does not increase the likelihood that the product candidate will ultimately receive FDA approval for any indication.

Furmonertinib is an investigational, novel, EGFR mutant-selective TKI that we are developing for the treatment of NSCLC patients across a broader set of EGFRm than are currently served by approved EGFR TKIs. Furmonertinib is currently only approved and commercially distributed by Allist in China as a first-line therapy to treat classical EGFRm NSCLC. The FDA has not approved furmonertinib for any use. We selected furmonertinib for global development against nonclassical, or uncommon, mutations based on preliminary reductions in tumor size observed in seven out of ten patients in first-line treatment with EGFR exon 20 insertion mutations in the ongoing Phase 1b clinical trial, the FAVOUR trial, conducted by Allist in China, and preclinical activity in PACC mutations, each a subtype of uncommon mutation. In a subsequent interim data readout from the FAVOUR trial of furmonertinib in first-line patients with locally advanced or metastatic EGFRm NSCLC with exon 20 insertion mutations, 79% of patients (n=22 out of 28 patients) were observed to experience a reduction in tumor size of at least 30%. Allist expects to release final results of the primary analysis from the FAVOUR study in 2024. If the future clinical trial results of the FAVOUR trial are unfavorable, our clinical development plans for furmonertinib, which include conducting our global, pivotal Phase 3 FURVENT clinical trial in first-line non-squamous locally advanced or metastatic EGFRm NSCLC patients with exon 20 insertion mutations, may be adversely affected. In 2021, we licensed from Allist the right to develop and commercialize furmonertinib worldwide, with the exception of greater China, which includes mainland China, Hong Kong, Macau and Taiwan.

As one of the most prevalent cancers in the world, lung cancer imposes a significant global burden on human health, and EGFRm NSCLC represents a significant proportion of those affected. Despite progress in the therapeutic landscape for EGFRm NSCLC, many patients, particularly those with uncommon mutations, such as exon 20 insertions or PACC mutations, are underserved by existing treatments. In an interim data readout from the FAVOUR trial of furmonertinib in first-line patients with locally advanced or metastatic EGFRm NSCLC with exon 20 insertion mutations, 79% of patients (n=22 out of 28 patients) were observed to experience a reduction in tumor size of at least 30% from the baseline in a patient without evidence of progression as measured by RECIST 1.1 criteria, which measurement of reduction is the threshold in this trial for a partial response and for inclusion in determination of the ORR, which is the primary endpoint of this trial. In the same interim data readout, those 79% of patients were observed to experience a 15.2 month median DOR. Interim results may not be indicative of final results; however, we believe these interim clinical results underscore furmonertinib’s potential in patients whose tumors contain an uncommon EGFRm.

We have entered into the Allist License Agreement, pursuant to which, we have, among other things, secured an exclusive, royalty bearing and sublicensable license under certain intellectual property, including patents and know-how, owned or controlled by Allist to develop and commercialize any product containing furmonertinib or any of its salts or derivatives as an active ingredient of a product, which is led by a joint collaboration committee, comprising of representatives from both Allist and us. Under the Allist License Agreement, we are obligated to pay Allist milestone payments up to an aggregate of $765.0 million upon the achievement of certain development, regulatory and sales milestone events as set forth in the Allist License Agreement. During the year ended December 31, 2023, we paid $5.0 million in clinical milestones to Allist. We are also obligated under the Allist License Agreement to pay Allist tiered royalties based on net sales of Licensed Products. See “Business — Licenses, Partnerships and Collaborations — Allist Agreements.”

Since our inception in April 2021, we have devoted substantially all of our resources to organizing and staffing our company, acquiring the rights to develop furmonertinib, clinical development of furmonertinib, business planning, raising capital, identifying potential product candidates, enhancing our intellectual property portfolio and undertaking research and clinical and preclinical studies for our development programs. We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have funded our operations to date primarily through the private placement of convertible preferred stock.

We have incurred significant operating losses since our inception and have not yet generated any revenue. Our net losses were $69.3 million and $36.9 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated deficit of $157.8 million. Our net losses may fluctuate significantly from

131

Table of Contents

quarter-to-quarter and year-to-year, depending on the timing of our preclinical studies, clinical trials and our expenditures on other research and development activities. We expect to continue to incur losses for the foreseeable future. We anticipate these losses will increase substantially as we:

In addition, if we obtain regulatory approval for furmonertinib or any product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution.

We do not expect to generate any revenues from product sales unless and until we successfully complete development and obtain regulatory approval for one or more product candidates. Accordingly, until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our cash needs through public or private equity offerings, debt financings, collaborations and licensing arrangements or other capital sources. 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 when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

On January 30, 2024, we completed the closing of our initial public offering of 9,722,222 shares of common stock at a price of $18.00 per share. Additionally, the underwriters exercised their option to purchase an additional 1,458,333 shares of common stock at a price of $18.00 per share. The shares of common stock began trading on the Nasdaq Global Market on January 26, 2024, under the symbol “AVBP”. We received net proceeds of $183.4 million, after deducting underwriting discounts and commissions and other estimated offering expenses. In addition, as a result of the closing of our initial public offering, our convertible preferred stock converted into 19,567,306 shares of common stock in January 2024.

Key Components of Our Results of Operations

Operating Expenses

Research and Development Expenses

To date, our research and development expenses have been related primarily to the development of furmonertinib, preclinical studies and other clinical activities related to our portfolio. Research and development costs are expensed as incurred and payments made prior to the receipt of goods or services to be used in research and development are deferred and recognized when the goods or services are received.

132

Table of Contents

Research and development costs include:

Our direct research and development expenses consist principally of external costs, such as fees paid to CROs and consultants in connection with our clinical trials for furmonertinib, preclinical and toxicology studies and costs related to manufacturing materials for clinical and preclinical studies. Prior to our identification of potential product candidates in 2022, we did not track external costs by program. Subsequent to the identification of potential product candidates, a significant majority of our direct research and development costs have been related to furmonertinib. We deploy our personnel resources across all of our research and development activities.

We plan to substantially increase our research and development expenses for the foreseeable future as we continue the development of furmonertinib and the identification and development of new product candidates. We cannot determine with certainty the timing of initiation, the duration or the completion costs of future clinical trials and preclinical studies of product candidates due to the inherently unpredictable nature of preclinical and clinical development. Clinical and preclinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates and development programs to pursue and how much funding to direct to each product candidate or program on an ongoing basis in response to the results of ongoing and future preclinical studies and clinical trials, regulatory developments and our ongoing assessments as to each product candidate’s commercial potential. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements.

Our future clinical development costs may vary significantly based on factors such as:

133

Table of Contents

General and Administrative Expenses

General and administrative expenses consist primarily of salaries, payroll taxes, employee benefits and stock-based compensation expenses for those individuals in executive, finance and other administrative functions. Other significant costs include legal fees relating to intellectual property and corporate matters, professional fees for accounting and consulting services, and insurance costs. We anticipate that our general and administrative expenses will increase in the future to support our continued research and development activities and, if any product candidates receive marketing approval, commercialization activities. We also anticipate increased expenses related to audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance premiums and investor relations costs associated with operating as a public company.

Interest Income

Interest income consists of interest earned on our cash equivalents and short-term investments.

Results of Operations

Comparison of the Years Ended December 31, 2023 and 2022

The following table summarizes our results of operations for the years ended December 31, 2023 and 2022:

​

Research and Development

We track outsourced clinical and preclinical costs and other external research and development costs associated with our lead product candidate, furmonertinib, and other discovery-stage programs. We do not track internal research and development costs by product candidate. The following table summarizes our research and development expenses for the years ended December 31, 2023 and 2022:

​

Research and development expenses were $64.9 million and $30.4 million for the years ended December 31, 2023 and 2022, respectively. The increase of $34.5 million was primarily due to an increase of $30.1 million related to our lead product candidate, furmonertinib, an increase of $3.1 million of higher personnel-related costs due to increased headcount and $1.2 million in preclinical discovery work. Cost related to furmonertinib increased as a result of increased costs related to our FURVENT Phase 3 clinical trial of $18.6 million, which includes a $5.0 million milestone incurred

134

Table of Contents

under the Allist License Agreement, and a $11.7 million increase in costs related to our FURTHER Phase 1 clinical trial due to additional patients added to the studies in second half of 2023, offset by decreases in costs related to our FAVOUR trial and other general furmonertinib costs totaling $0.2 million.

General and Administrative

General and administrative expenses were $9.7 million and $6.5 million for the years ended December 31, 2023 and 2022, respectively. The increase of $3.2 million was due primarily to increases of $2.2 million in professional services and $1.0 million in personnel-related expenses.

Interest Income

Interest income was $5.3 million for the year ended December 31, 2023 and consisted of interest earned on our cash equivalents and short-term investments. For the year ended December 31, 2022, we did not earn any interest income.

Liquidity and Capital Resources

Sources of Liquidity

We have funded our operations primarily through the private placement of convertible preferred stock. To date, we have raised gross proceeds of $305.0 million from the issuance of convertible preferred stock. As of December 31, 2023, we had cash and cash equivalents of $150.4 million. In the first quarter of 2024, we completed our initial public offering of 11,180,555 shares of our common stock at a price to the public of $18.00 per share, including the exercise in full by the underwriters of their option to purchase 1,458,333 additional shares of our common stock. Including the option exercise, our aggregate net proceeds from the offering were $183.4 million, net of underwriting discounts, commissions and estimated offering costs.

Future Funding Requirements

We plan to continue to fund our operating expenses and capital expenditure requirements through additional public or private equity offerings, debt financings, collaborations and licensing arrangements or other capital sources. Debt or equity financing or collaborations and partnerships with other entities may not be available on a timely basis, on acceptable terms, or at all. In addition, we may be required to scale back or discontinue the advancement of product candidates, reduce headcount or reduce other operating expenses. This could have an adverse impact on our ability to achieve certain of our planned objectives, and thus, materially harm our business. Our ability to successfully transition to profitability will depend upon obtaining additional financing and achieving a level of product sales adequate to support our cost structure. We cannot be assured that we will ever be profitable or generate positive cash flows from operating activities.

We believe that our existing cash and cash equivalents, together with the net proceeds from our initial public offering, will be sufficient to meet our anticipated cash requirements into 2026. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. We have based this estimate on assumptions that may prove to be wrong, and we could deplete our capital resources sooner than we expect.

Our future capital requirements will depend on many factors, including:

135

Table of Contents

Until such time, if ever, as we can generate substantial product revenues to support our cost structure, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, collaborations and licensing arrangements or other sources. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be or could be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our platform technology, future revenue streams, research programs or product candidates or may have to grant licenses on terms that may not be favorable to us and/or may reduce the value of our common stock. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market our product candidates even if we would otherwise prefer to develop and market such product candidates ourselves.

Cash Flows

The following table summarizes our cash flows for the periods indicated:

​

Operating Activities

Net cash used in operating activities was $55.8 million for the year ended December 31, 2023 reflecting our net loss of $69.3 million that was offset by $0.9 million in stock-based compensation and a $12.6 million net change in our operating assets and liabilities attributable to the timing in which we pay our vendors for research and development activities.

136

Table of Contents

Net cash used in operating activities was $43.6 million for the year ended December 31, 2022 reflecting our net loss of $36.9 million and a $7.1 million net change in our operating assets and liabilities attributable to the timing in which we pay our vendors for research and development activities offset, in part, by $0.4 million in stock-based compensation.

Investing Activities

Net cash used in investing activities for the year ended December 31, 2023 included $25.0 million of purchases of short-term investments, offset by $25.0 of maturities of short-term investments.

Financing Activities

Net cash provided by financing activities was $42.9 million for the year ended December 31, 2023, due to $44.9 million of net proceeds from the issuance of Series B convertible preferred stock and $0.4 million of proceeds from the exercise of stock options offset by a $2.4 million payment of deferred offering costs.

Net cash provided by financing activities was $169.7 million for the year ended December 31, 2022, due to the net proceeds of $60.0 million from the issuance of Series A convertible preferred stock and net proceeds of $109.7 million from the issuance of Series B convertible preferred stock.

Contractual Obligations and Commitments

The following table summarizes our contractual obligations as of December 31, 2023 and the effects that such obligations are expected to have on our liquidity and cash flows in future periods:

​

​

As of December 31, 2023, except for the operating lease, we did not have any long-term obligations, capital lease obligations, purchase obligation or long-term liabilities. We enter into contracts in the normal course of business with third-party CROs and clinical trial sites for our clinical trials, and with supply vendors for other services and products for operating purposes. These contracts generally provide for termination after a notice period, and, therefore, are cancelable contracts.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued research and development and stock-based compensation expenses. We base our estimates on historical experience, 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 these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our accompanying financial statements appearing elsewhere in this Annual Report, we believe the following accounting policies to be most critical to the preparation of our financial statements.

137

Table of Contents

Research and Development Accruals

Research and development expenses consist primarily of costs incurred in connection with the development of our lead product candidate. We expense research and development costs as incurred.

We accrue expenses for pre-clinical and clinical studies and activities performed by third parties based upon estimates of the proportion of work completed over the term of the individual trial and patient enrollment rates in accordance with agreements with third parties. We determine the estimates by reviewing contracts, vendor agreements and purchase orders, and through discussions with our internal clinical personnel and external service providers as to the progress or stage of completion of activities or services and the agreed-upon fee to be paid for such services. However, actual costs and timing of clinical trials are highly uncertain, subject to risks and may change depending upon a number of factors, including our clinical development plan.

We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Non-refundable advance payments for goods and services, including fees for manufacturing and distribution of clinical and pre-clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

Milestone payments within our licensing and collaboration arrangements will be recognized when achievement of the milestone is deemed probable to occur. To the extent products are commercialized and future economic benefit has been established, commercial milestones that become probable are capitalized and amortized over the estimated remaining useful life of the intellectual property. In addition, we will accrue royalty expense and sublicense non-royalty payments, as applicable, for the amount we are obligated to pay, with adjustments as sales are made.

Stock-Based Compensation Expense

We maintain a stock-based compensation plan as a long-term incentive for employees and non-employee consultants. The plan allows for the issuance of incentive stock options and non-qualified stock options.

We recognize stock-based compensation expense for stock options on a straight-line basis over the requisite service period, which is the vesting period of the awards. Our stock-based compensation expense is based upon the grant date fair value of stock options estimated using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the use of highly subjective assumptions to determine the fair value of our stock options.

Estimating the fair value of stock options as of the grant date using the Black-Scholes option pricing model is affected by assumptions regarding a number of variables. Changes in the assumptions can materially affect the fair value and ultimately how much stock-based compensation expense is recognized. Several of these inputs are subjective and require judgment to develop, including the fair value of our common stock for grants made prior to our initial public offering and expected volatility. We will continue to use judgment in evaluating these inputs utilized for our stock-based compensation expense calculations on a prospective basis.

​

JOBS Act and Emerging Growth Company Status

As an emerging growth company under the JOBS Act, we can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period for complying with new or revised accounting standards and as a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates. We intend to rely on other exemptions provided by the JOBS Act, including without limitation, not being required to comply with the auditor attestation requirements of Section 404(b) of Sarbanes-Oxley.

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of the consummation of our initial public offering, (ii) the last day of the fiscal year in which we have

138

Table of Contents

total annual gross revenue of at least $1.235 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if, among other factors, the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year (subject to certain conditions), or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We are also a smaller reporting company as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as our voting and non-voting common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and our voting and non-voting common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

Recent Accounting Pronouncements

A description of recent accounting pronouncements that may potentially impact our financial position, results of operations or cash flows is disclosed in Note 3 to our accompanying financial statements appearing elsewhere in this Annual Report.
