Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and related notes included elsewhere in this Annual Report. This discussion and analysis and other parts of this Annual Report contain forward-looking statements based upon current beliefs, plans and expectations that involve risks, uncertainties and assumptions, such as statements regarding our plans, objectives, expectations, intentions and projections. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under Part I, Item 1A “Risk Factors” and elsewhere in this Annual Report. 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 entitled “Special Note Regarding Forward-Looking Statements.”
Overview
We are a clinical-stage oncology company focused on the development of MasterKey therapies to treat patients with genetically defined tumors. The foundation of our company is built upon a deep understanding of cancer genetics, onco-protein structure and function, and medicinal chemistry. Our MasterKey therapies are designed to address a broad spectrum of genetically defined tumors, overcome resistance, minimize wild-type mediated toxicities, and be brain-penetrant to treat central nervous system (CNS) disease. Our compounds target families of oncogenic mutations in clinically validated pathways. We are advancing two clinical-stage programs: BDTX-1535, a brain-penetrant, fourth-generation EGFR MasterKey inhibitor, targeting epidermal growth factor receptor mutant (EGFRm) non-small cell lung cancer (NSCLC) and glioblastoma (GBM), and BDTX-4933, a brain-penetrant, RAF MasterKey inhibitor targeting KRAS, NRAS and BRAF alterations in solid tumors.
We believe that our lead product candidate, BDTX-1535, has the potential to treat patients with EGFR mutated (EGFRm) NSCLC in both early-line and later-line settings based upon BDTX-1535’s ability to address approximately 50 oncogenic mutations with greater potency than other EGFR TKI’s, as well as uniquely target the C797S resistance mutation which can be acquired after treatment with osimertinib. In our Phase 1 trial in patients with advanced/metastatic EGFR mutant NSCLC, BDTX-1535 was shown to be well tolerated and achieve durable clinical responses in patients whose tumors expressed a range of mutation subtypes, including the acquired C797S resistance mutation and a spectrum of non-classical mutations. We are currently evaluating BDTX-1535 in a Phase 2 clinical trial in patients with EGFRm NSCLC in the second- and third-line settings with non-classical driver mutations and acquired C797S resistance mutation, and in the first-line setting in patients with EGFRm NSCLC harboring non-classical EGFR mutations. We expect to announce results from the second- and third-line cohorts in the third quarter of 2024 and results from the first-line cohort in 2025. We are also assessing the potential development of BDTX-1535 for patients with EGFRm NSCLC following adjuvant treatment with osimertinib, where the broad mutation coverage of BDTX-1535 of C797S and non-classical mutations may be of benefit.
We released top-line GBM results from the BDTX-1535 Phase 1 dose escalation study in the fourth quarter of 2023, showing clinical activity in heavily pretreated patients with GBM. BDTX-1535 was shown to be generally well tolerated and no new safety signals were observed. In the fourth quarter of 2023, enrollment began in a “window of opportunity” Phase 0/1 trial of BDTX-1535 in patients with recurrent high-grade glioma. We expect to present Phase 1 data and “window of opportunity” results in the second quarter of 2024, which will inform potential next steps in the development of BDTX-1535 in GBM.

Our second product candidate, BDTX-4933, is designed to be a potent and selective, reversible oral inhibitor that targets broad families of oncogenic BRAF, KRAS and NRAS alterations. BDTX-4933 selectively targets constitutively active RAF dimers resulting from either BRAF mutations or other upstream oncogenic MAPK pathway alterations, such as KRAS and NRAS alterations. In preclinical tumor models, we observed that BDTX-4933 demonstrated brain-penetrant activity and achieved regression of tumors carrying a broad spectrum of KRAS mutations, NRAS alterations, as well as BRAF Class I, II, and III mutations. We initiated a Phase 1 clinical trial for BDTX-4933 in the second quarter of 2023 in patients with BRAF and select KRAS and NRAS mutation-positive cancers, with an emphasis on patients with non-G12C KRAS mutant NSCLC. The trial is currently in dose escalation with data expected in the fourth quarter of 2024.
Since our inception in 2014, we have devoted substantially all of our efforts and financial resources to organizing and staffing our company, business planning, raising capital, discovering product candidates and securing related intellectual property rights while conducting research and development activities for our programs. We do not have any products approved for sale and have not generated any revenue from product sales. We may never be able to develop or commercialize a marketable product. We have not yet successfully completed any pivotal clinical trials, obtained any regulatory approvals, manufactured a commercial-scale drug, or conducted sales and marketing activities.
To date, we have funded our operations with proceeds from the sale of common stock and preferred stock. Since inception, we have incurred significant operating losses. Our net losses were $82.4 million and $91.2 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated deficit of $417.4 million. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of our current or future product candidates. We expect that our expenses and capital requirements will increase substantially in connection with our ongoing activities, particularly if and as we:
• advance clinical trials for BDTX-1535 and BDTX-4933;
• obtain, maintain, expand and protect our intellectual property portfolio;
• attract and retain key clinical, scientific, management and commercial personnel;
• seek marketing approvals for our product candidates that successfully complete clinical trials, if any; and
• acquire or in-license additional product candidates.
As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, which may include collaborations with other companies or other strategic transactions. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable 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 one or more of our product candidates, and reduce headcount and general and administrative costs.
Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.
Additionally, we continue to actively monitor macroeconomic conditions and market volatility resulting from global economic developments, political unrest, high inflation, disruptions in capital markets, changes in international trade relationships and military conflicts, and health crises. While we believe such factors have had no significant impact on our business or financial results during the periods presented, future developments and potential impacts on our business are uncertain and cannot be predicted with confidence.

Table of Contents
As of December 31, 2023, we had cash, cash equivalents and investments of $131.4 million, which we believe will enable us to fund our operating expenses and capital expenditure requirements into the second quarter of 2025. We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See “— Liquidity and capital resources .” To finance our operations beyond that point, we will need to raise additional capital, which cannot be assured. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our product candidates or other research and development initiatives.
Components of our results of operations
Revenue
To date, we have not generated any revenue from any sources, including from product sales, and we do not expect to generate any revenue from the sale of products in the foreseeable future. If our development efforts for our product candidates are successful and result in regulatory approval, or license agreements with third parties, we may generate revenue in the future from product sales. However, there can be no assurance as to when we will generate such revenue, if at all.
Operating expenses
Research and development expenses
Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts and the development of our product candidates. We expense research and development costs as incurred, which include:
• expenses incurred to conduct the necessary preclinical studies and clinical trials required to obtain regulatory approval;
• expenses incurred under agreements with contract research organizations, or CROs, that are primarily engaged in the oversight and conduct of our drug discovery efforts, preclinical studies, and clinical trials as well as under agreements with contract manufacturing organizations, or CMOs, that are primarily engaged to provide preclinical and clinical drug substance and product for our research and development programs;
• other costs related to the conduct of preclinical studies, clinical trials, and our drug discovery efforts, including acquiring and manufacturing materials, manufacturing validation batches, fees to investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development support services;
• payments made in cash or equity securities under third-party licensing, acquisition and option agreements;
• employee-related expenses, including salaries and benefits, travel and stock-based compensation expense for employees engaged in research and development functions;
• costs related to compliance with regulatory requirements; and
• allocated facilities-related costs, depreciation and other expenses, which include rent and utilities.
We recognize external development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our service providers. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual costs. Any nonrefundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses. Such amounts are expensed as the related goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered or the services rendered.
123
Table of Contents
Our direct external research and development expenses consist primarily of external costs, such as fees paid to outside consultants, CROs, CMOs and research laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses also include fees incurred under license, acquisition and option agreements. We do not allocate employee costs, costs associated with our discovery efforts, laboratory supplies, and facilities, including depreciation or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to conduct our research and discovery as well as for managing our preclinical development, process development, manufacturing and clinical development activities. These employees work across multiple programs and, therefore, we do not track their costs by program.
Development activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will increase substantially over the next several years as we continue our clinical trials for BDTX-1535 and BDTX-4933. In addition, we may incur additional expenses related to milestone and royalty payments payable to third parties with whom we may enter into license, acquisition and option agreements to acquire the rights to future product candidates.
At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from any of our product candidates. The successful development and commercialization of our product candidates is highly uncertain. This uncertainty is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of the following:
• the scope, progress, outcome and costs of our clinical trials and other development activities;
• successful patient enrollment in and the initiation and completion of clinical trials;
• the timing, receipt and terms of any marketing approvals from applicable regulatory authorities including the U.S. Food and Drug Administration (FDA) and non-U.S. regulators;
• the extent of any required post-marketing approval commitments to applicable regulatory authorities;
• establishing clinical and commercial manufacturing capabilities or making arrangements with third-party manufacturers in order to ensure that we or our third-party manufacturers are able to make product successfully;
• development and timely delivery of clinical-grade and commercial-grade drug formulations that can be used in our clinical trials and for commercial launch;
• obtaining, maintaining, defending and enforcing patent claims and other intellectual property rights;
• significant and changing government regulation;
• launching commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; and
• maintaining a continued acceptable safety profile of our product candidates following approval, if any, of our product candidates.
Any changes in the outcome of any of these variables with respect to the development of our product candidates could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other testing beyond those that we currently expect or if we experience significant delays in enrollment in any of our planned clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.

Table of Contents
General and administrative expenses
General and administrative expenses consist primarily of salaries and benefits, travel and stock-based compensation expense for personnel in executive, business development, finance, human resources, legal, information technology, pre-commercial and support personnel functions. General and administrative expenses also include direct and allocated facility-related costs as well as insurance costs and professional fees for legal, patent, consulting, investor and public relations, accounting and audit services.
We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support continued development of our product candidates and prepare for potential commercialization activities. Additionally, if and when we believe a regulatory approval of a product candidate appears likely, we anticipate an increase in payroll and other employee-related expenses as a result of our preparation for commercial operations, especially as it relates to the sales and marketing of that product candidate.
Other income (expense)
Other income (expense) consists primarily of interest income earned on our cash equivalents and investment balances, sublease income, realized and unrealized foreign currency transaction gains and losses, and gain (loss) on sale of IP related to equity method investment.
Equity in (losses) of unconsolidated entity
Equity in (losses) of unconsolidated entity consists of our share of equity method investee losses on the basis of our equity ownership percentage and IPR&D charges resulting from basis differences.

Other expenses 1,938 1,564 374
$ 59,350 $ 64,437 $ (5,087)
The decrease of $5.1 million was primarily due to an increase of $12.7 million related to the progression of our clinical trial for BDTX-1535, offset by decreased spend relating to other research programs and platform development of $5.6 million due to reduced spending on early discovery projects as we deepen our focus on our clinical-stage assets. In addition, BDTX-189 expenses decreased $7.1 million due to the discontinuation of the development of BDTX-189 to focus on the development of BDTX-1535 and BDTX-4933. Personnel expenses decreased $4.5 million as a result of the realignment of our workforce in April 2022 to focus on upcoming milestones for our clinical trials.
General and administrative
General and administrative expenses were $27.1 million for the year ended December 31, 2023, compared to $28.4 million for the year ended December 31, 2022. The decrease of $1.3 million was primarily due to a decrease in legal and other professional fees.
Other income (expense)
Other income was $4.0 million for the year ended December 31, 2023, compared to $3.9 million for the year ended December 31, 2022. Although the increase of $0.1 million is low year over year, the composition changed in 2023 to primarily sublease income and accretion on investments, compared to 2022 when it was primarily the gain on sale of IP related to the equity method investment in Launchpad.
Equity in (losses) of unconsolidated entity
There was no equity in (losses) of unconsolidated entity for the year ended December 31, 2023, compared to $2.3 million for the year ended December 31, 2022. The increase was attributable to no equity method investments in 2023 compared to 2022 when we reported our share of equity method investee losses on the basis of our equity ownership percentage as well as IPR&D charges resulting from basis differences.

Liquidity and capital resources
Sources of liquidity
Since our inception, we have not generated any revenue from any product sales or any other sources and have incurred significant operating losses and negative cash flows from our operations. We have not yet commercialized any of our product candidates, and we do not expect to generate revenue from sales of any product candidates for several years, if at all. We have funded our operations to date primarily with proceeds from the sale of common and preferred stock.
On February 3, 2020, we completed an IPO of 12,174,263 shares of our common stock, including the exercise in full by the underwriters of their option to purchase up to 1,587,947 additional shares of common stock, for aggregate gross proceeds of $231.3 million. We received $212.1 million in net proceeds after deducting underwriting discounts and commissions and other estimated offering expenses payable by us. Through December 31, 2023, we had received net cash proceeds of $200.6 million from previous sales of our preferred stock and as of December 31, 2023, we had cash, cash equivalents and investments of $131.4 million.
On November 14, 2022, we filed a shelf registration statement on Form S-3 (the Shelf Registration Statement) with the SEC, which covers the offering, issuance and sale of our common stock, preferred stock, debt securities, warrants and/or units of any combination thereof up to a maximum price of $500 million. We simultaneously entered into an Open Market Sale Agreement SM (the Sales Agreement) with Jefferies LLC (Jefferies), as sales agent, to provide for the issuance and sale by us of up to $150 million of our common stock, or the Shares, from time to time through Jefferies as our sales agent (the ATM Program). The Shelf Registration Statement became effective on November 22, 2022. Upon delivery of a placement notice and subject to the terms and conditions of the Sales Agreement, Jefferies may sell the Shares by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) promulgated under the Securities Act. We may sell the Shares in amounts and at times to be determined by us from time to time subject to the terms and conditions of the Sales Agreement, but we have no obligation to sell any Shares under the Sales Agreement. We or Jefferies may suspend or terminate the offering of Shares upon notice to the other party and subject to other conditions. As of December 31, 2023, no sales have been made pursuant to the ATM Program.
On July 5, 2023, we completed an underwritten public offering (the Follow-on Offering) of 15,000,000 shares of our common stock at a price to the public of $5.00 per share. The aggregate net proceeds from the Follow-on Offering totaled approximately $71.6 million after deducting underwriting discounts and commissions, as well as other offering expenses. The underwriters did not exercise any portion of their 30-day overallotment option to purchase up to an additional 2,250,000 shares of the Company’s common stock at the public offering price, which expired on July 29, 2023, and therefore no additional proceeds from the Follow-on Offering were received.

Operating activities
During the year ended December 31, 2023, we used cash in operating activities of $66.7 million, primarily resulting from our net loss of $82.4 million, partially offset by the non-cash charge related to stock compensation expense of $9.6 million, a decrease in prepaid expenses and other current assets as development services were performed, and an increase in accounts payable, accrued expenses and other current liabilities.
During the year ended December 31, 2022, we used cash in operating activities of $85.1 million, primarily resulting from our net loss of $91.2 million, partially offset by the non-cash charge related to stock compensation expense of $12.2 million, and a decrease in accounts payable, accrued expenses and other current liabilities.
Changes in accounts payable and accrued expenses in all periods were generally due to growth in our business, the advancement of our product candidates, and the timing of vendor invoicing and payments.
Investing activities
During the year ended December 31, 2023, we had cash provided by investing activities of $16.3 million primarily from the sales and maturities of investments.
During the year ended December 31, 2022, we had cash provided by investing activities of $53.4 million primarily from the sales and maturities of investments.
Financing activities
During the year ended December 31, 2023, we had cash provided by financing activities of $71.9 million, consisting of proceeds from the Follow-on Offering in July 2023 as well as participation in the employee stock purchase plan.
During the year ended December 31, 2022, we had cash provided by financing activities of $0.2 million, consisting of proceeds from the exercise of stock options.
Funding requirements
We expect our expenses to increase substantially in connection with our ongoing activities, particularly as we advance clinical trials of our product candidates. In addition, we expect to incur additional costs associated with operating as a public company, including significant legal, accounting, investor relations and other expenses. The timing and amount of our operating expenditures will depend largely on our ability to:
• advance BDTX-1535 and BDTX-4933 through clinical trials;
• manufacture, or have manufactured on our behalf, our drug material and develop processes for late stage and commercial manufacturing;
• seek regulatory approvals for any product candidates that successfully complete clinical trials;
• establish a sales, marketing, medical affairs and distribution infrastructure to commercialize any product candidates for which we may obtain marketing approval and intend to commercialize on our own;
• hire additional clinical, quality control and scientific personnel; and
• obtain, maintain, expand and protect our intellectual property portfolio.
128
Table of Contents
As of December 31, 2023, we had cash, cash equivalents and investments of $131.4 million, which we believe will fund our operating expenses and capital expenditure requirements into the second quarter of 2025. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. We anticipate that we will require additional capital as we seek regulatory approval of our product candidates and if we choose to pursue in-licenses or acquisitions of other product candidates. If we receive regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution, depending on where we choose to commercialize.
Because of the numerous risks and uncertainties associated with research, development and commercialization of product candidates, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to further reduce or terminate our operations. Our future funding requirements will depend on and could increase significantly as a result of many factors, including:
• the scope, progress, results and costs of developing our product candidates, and conducting clinical trials;
• the costs, timing and outcome of regulatory review of our product candidates;
• the costs, timing and ability to manufacture our product candidates to supply our clinical development efforts and our clinical trials;
• the costs of future activities, including product sales, medical affairs, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval;
• subject to receipt of regulatory approval, the costs of commercialization activities for our product candidates, to the extent such costs are not the responsibility of any future collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing capabilities;
• the ability to receive additional non-dilutive funding;
• the revenue, if any, received from commercial sale of our products, should any of our product candidates receive marketing approval;
• the costs of preparing, filing and prosecuting patent applications, obtaining, maintaining, expanding 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;
• the extent to which we acquire or in-license other product candidates and technologies; and
• the costs of operating as a public company.
As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time, if ever, as we can generate substantial product revenue from product sales, we expect to finance our operations through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships and alliances or marketing, distribution or licensing arrangements with third parties or through other sources of financing. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. However, the trading prices for our common stock and for other biopharmaceutical companies have been highly volatile. As a result, we may face difficulties raising capital through sales of our common stock, and such sales may be on unfavorable terms. Similarly, adverse macroeconomic conditions and market volatility resulting from global economic developments, political unrest, high inflation, global health crises, or other factors could materially and adversely affect our ability to consummate an equity or debt financing on favorable terms or at all. We may be unable to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all.
129
Table of Contents
To the extent that we raise additional capital through the sale of private or public equity or convertible debt securities, the ownership interest of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences and anti-dilution protections that could adversely affect the rights of our common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business. In addition, debt financing may involve significant cash payment obligations and specific financial ratios that may restrict our ability to operate our business would result in fixed payment obligations.
If we raise additional funds through collaborations, strategic partnerships and alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our research, 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, obtain capital through arrangements with collaborators on terms unfavorable to us or pursue merger or acquisition strategies, all of which could adversely affect the holdings or the rights of our stockholders.
Critical accounting policies and significant judgments and use of estimates
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States (GAAP). The preparation of our consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses. We base our estimates on historical experience, known trends and events and various other factors that we believe are 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. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.
While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.
Accrued research and development expenses
As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our applicable personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in the consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of the estimates with the service providers and make adjustments if necessary. Examples of estimated accrued research and development expenses include fees paid to:
• vendors, including research laboratories, in connection with preclinical development activities;
• CROs and investigative sites in connection with preclinical studies and clinical trials; and
• CMOs in connection with drug substance and drug product formulation of preclinical studies and clinical trial materials.
130
Table of Contents
We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple research institutions and CROs that supply, conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust the accrual or the prepaid expense accordingly. 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 measure stock options and other stock-based awards granted to employees, non-employees and directors based on their fair value on the date of the grant and recognize the corresponding compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective award. We have generally only issued stock options and restricted stock units with service-based vesting conditions and record the expense for these awards using the straight-line method. For stock options or restricted stock units issued with performance-based vesting conditions, the related stock compensation expense is recognized based on the grant date fair value when achievement of the performance condition is deemed probable. The graded-vesting method would apply to all stock-based awards with performance-based vesting conditions or to awards with both service-based and performance-based vesting conditions.
We have historically granted stock options with exercise prices equivalent to the fair value of our common stock as of the date of grant. For grants of restricted stock units, we base the fair value on the stock price as of the date of grant.
We account for stock-based awards granted to employees and non-employees at fair value, which is measured using the Black-Scholes option-pricing model. The measurement date for the awards is generally the date of grant. Stock-based compensation costs are recognized as expenses over the requisite service period, which is generally the vesting period, on a straight-line basis for all time-vested awards.
We estimate the fair value of each stock option grant using the Black-Scholes option-pricing model, which uses as inputs the fair value of our common stock and assumptions we make for the volatility of our common stock, the expected term of our stock options, the risk-free interest rate for a period that approximates the expected term of our stock options and our expected dividend yield.
Recently issued accounting pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our consolidated financial statements appearing elsewhere in this Annual Report.
Emerging growth company and smaller reporting company status
The Jumpstart Our Business Startups Act of 2012 (the JOBS Act) permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We have elected to not “opt out” of this provision and, as a result, we will adopt new or revised accounting standards at the time private companies adopt the new or revised accounting standard and will do so until such time that we either (i) irrevocably elect to “opt out” of such extended transition period or (ii) no longer qualify as an emerging growth company.

We are also a “smaller reporting company” meaning that the market value of our stock held by non-affiliates is less than $700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. We may continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250 million or (ii) our annual revenue was less than $100 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.
