Annual Report 2021

Plain-text annual report

2021 Annual Report To Our Shareholders: I am pleased to report that Arvinas made tremendous progress in 2021. We began the year with a great deal of confidence after the exciting interim data for our estrogen receptor (ER) degrader, ARV-471, and our androgen receptor (AR) degrader, bavdegalutamide (ARV-110), presented in December 2020. These positive results not only validated our PROTAC® platform, but also positioned ARV-471 and bavdegalutamide as potentially significant advances for the treatment of patients with breast and prostate cancers. That momentum continued throughout 2021 as we realized significant milestones with those two lead programs. Our novel PROTAC® Discovery Engine platform has driven our promising pipeline, and we believe it remains the most advanced and successful platform in protein degradation. Our accomplishments to date set the stage for Arvinas to begin three planned pivotal trials in 2022, one with bavdegalutamide and two with ARV-471. In July, we entered a transformational global collaboration with Pfizer to co-develop and co-commercialize ARV-471. Together, we intend to develop ARV-471 as an endocrine backbone therapy of choice in breast cancer, from the adjuvant setting through late-line metastatic disease. This collaboration will accelerate the development of ARV-471 by leveraging Pfizer’s global reach and expertise in breast cancer. It also strengthens our ability to continue to develop new and important PROTAC® degraders in additional disease areas with high unmet need. In December, we presented updated and compelling ARV-471 Phase 1 dose escalation data that reinforced ARV-471’s favorable tolerability profile and anti-tumor activity in patients with locally advanced or metastatic ER-positive/human epidermal growth factor receptor 2 (HER2)-negative breast cancer (ER+/HER2-). Together with Pfizer, we intend to advance ARV-471 into two Phase 3 trials by the end of 2022. Also in December, we shared our first-ever preclinical data from our B-cell lymphoma 6 protein (BCL6) program, which highlighted our PROTAC® degrader’s efficacy in models of diffuse B-cell lymphoma (DLBCL). We look forward to sharing more data on our BCL6 and other preclinical programs as we progress towards clinical development. We are committed to delivering four investigational new drug applications by the end of 2023. 2022 is off to an exciting start. In February, we presented completed Phase 1 dose escalation data and interim Phase 2 data with bavdegalutamide, currently being evaluated in men with metastatic castration-resistant prostate cancer. This update provided further evidence of clinical benefit and identified a particularly robust response in tumors with a specific genetic mutation, suggesting the potential for an accelerated pathway for bavdegalutamide, and we intend to initiate a pivotal trial by the end of 2022. We are enthusiastic about the potential bavdegalutamide could have for patients with prostate cancer, initially in a genetically defined population, and ultimately in a broader population. We anticipate that the remainder of 2022 will be rich with progress, including the initiation of three planned pivotal trials, ongoing progress with our preclinical programs, and additional data readouts from our clinical programs. I am proud to lead such a talented group of professionals who are ready to execute on our ambitious plans. We remain steadfast in our goal to build a global, fully integrated biopharmaceutical company bringing new medicines to patients with serious diseases. I extend my sincerest gratitude to all Arvinas employees, patients, clinical collaborators, and shareholders – your support continues to drive our success.

Risk Factor Summary Our business is subject to a number of risks that if realized could materially affect ff our business, prospects, operating results and financial condition. These risks are discussed more fully in the “Risk Factors” section of this Annual Report on Form 10-K. These risks include the following: • We have incurred significant losses since our inception. To date, we have not generated any revenue from product sales and may never be profitable. We expect to incur losses over at least the next several years and may never achieve or maintain profitability. Our net losses totaled $191.0 million, $119.3 million and $70.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. • We will need substantial additional funding.

Business. Overvirr ew PART I We are a clinical-stage biopharmaceutical company dedicated to improving the lives of patients to engineer proteolysis targeting chimeras, or PROTACTT ng from debilitating and life-threatening diseases through the discovery, development and sufferi ff commercialization of therapies to degrade disease-causing proteins. We use our PROTAC Discovery Engine, our proprietary technology platformff degraders, that are designed to harness the body’s own natural protein disposal system to selectively remove disease-causing proteins. We believe that our targeted protein degradation approach is a therapeutic modality that may provide distinct advantages over existing modalities, including traditional small molecule therapies and gene-based medicines. Our small-molecule PROTACTT technology has the potential to address a broad range of intracellular disease targets, including those representing the up to 80% of proteins that currently cannot be addressed by existing small molecule therapies, commonly referred to as “undruggable” targets. We are using our PROTACTT target diseases in oncology (including immuno-oncology), neuroscience, and other therapeutic areas. Our three lead product candidates are bavdegalutamide, ARV-RR 471 and ARV-RR 766. Discovery Engine to build an extensive pipeline of protein degradation product candidates to targeted protein Bavdegadd lutamide (ARV-110) VV We are developing bavdegalutamide, an investigational orally bioavailable PROTAC protein degrader targeting the androgen receptor protein, or AR, forff the treatment of men with metastatic castration-resistant prostate cancer, or mCRPC. We initiated a Phase 1 clinical trial of bavdegalutamide designed to assess the safety, tolerability and pharmacokinetics of bavdegalutamide and also includes measures of anti-tumor activity as secondary endpoints, including reduction in prostate specific antigen, or PSA, a well-recognized biomarker of prostate cancer progression. We received Fast Track designation for bavdegalutamide for mCRPC in May 2019. We have completed dose escalation in the Phase 1 clinical trial. In the fourth quarter of 2020, we initiated rth quarter ARDENT, tTT he Phase 2 single agent expansion portion of the bavdegalutamide clinical trial. In the fouff of 2021, we initiated a Phase 1b clinical trial of bavdegalutamide in combination with abiraterone for the treatment of men with mCRPC. In the first half of 2022, we intend to initiate discussions with the U.S. Food and Drug Administration, or FDA, about the potential forff an accelerated approval pathway with bavdegalutamide in molecularly defined mCRPC and finalize a partnership for a companion diagnostic. In the second half of 2022, we plan to initiate a pivotal trial evaluating bavdegalutamide in patients with mCRPC who have progressed on or after novel hormonal agents and have tumors that harbor AR T878X/H875Y tumor mutations. We anticipate that future studies will be planned to explore the potential to treat earlier-line patients with AR-dependent tumors who may benefit from bavdegalutamide therapy. VV ARV-471 We are developing ARV-RR 471, an investigational orally bioavailable PROTACTT protein degrader targeting TT the estrogen receptor protein, or ER, for the treatment of patients with locally advanced or metastatic ER positive / HER2 negative breast cancer. We initiated a Phase 1 clinical trial of ARV-RR 471 designed to assess the safety, tolerability and pharmacokinetics of ARV-RR 471, which also includes measures of anti-tumor activity as rth quarter of 2020, we initiated a Phase 1b cohort expansion of ARV-RR 471 in secondary endpoints.

In the first quarter of 2021, we initiated VERITAC, the Phase 2 single agent expansion cohort of the ARV-RR 471 clinical trial. In July 2021, we entered into a collaboration agreement with Pfizer, pursuant to which we granted Pfizer worldwide coexclusive rights to develop and commercialize ARV-RR 471. In December 2021, we presented data from the dose escalation portion of the Phase 1/2 clinical trial at the San Antonio Breast Cancer Symposium.

In preclinical studies, ARV-RR 766 degraded all tested resistance- driving point mutations of AR, including L702H, a mutation associated with treatment with abiraterone and other AR-pathway therapies, which bavdegalutamide did not degrade in preclinical studies. In 2021, we initiated a Phase 1 clinical trial for ARV-RR 766 designed to assess the safety, tolerability and pharmacokinetics of ARV-RR 766, which also includes measures of anti-tumor activity as secondary endpoints, including reduction in PSA. In the second half of 2022, we plan to present Phase 1 dose escalation data and initiate a Phase 2 expansion trial for the treatment of men with mCRPC. Each of bavdegalutamide, ARV-RR 471 and ARV-RR 766 has demonstrated potent and selective protein degradation in our preclinical studies. We believe favorable clinical trial results in these initial oncology programs could provide validation of our platform as a new therapeutic modality forff diseases caused by dysregulated intracellular proteins regardless of therapeutic area. the potential treatment of We have designed and optimized our PROTACTT Discovery Engine for the discovery of PROTACTT targeted protein degraders to tag a target protein for degradation through the ubiquitin proteasome therapeutics to address diseases caused by abnormal proteins or aberrant protein expression. We engineer our PROTACTT system, one of the cell’s natural protein disposal systems, and then to iteratively degrade additional target protein molecules. The PROTACTT Discovery Engine includes advanced screening capabilities, including in- house high-throughput and deoxyribonucleic acid, or DNA, -encoded library screening abilities that are tailored to the needs of incorporation into PROTACTT Following selection and identification, we use tools including predictive computational modeling and privileged linkers that allow the potential for increased potency and selectivity. Finally, we have utilized our own proprietary PROTAC-specific optimization strategies, which we refer to as the Arvinas Rules, to create PROTACTT degraders that, for example, are capable of being delivered through multiple routes of administration, including oral delivery, as well as PROTACTT targeted protein degraders that are able to penetrate the blood brain barrier. protein degraders and to optimize their drug-like properties. In addition to our clinical product candidates, we are expanding our pipeline by utilizing our platform to potentially address currently undruggable targets. Unlike existing small molecule inhibitor therapies, our PROTACTT y targeted protein degraders can degrade proteins using any available binding site, including low-affinit active binding sites or non-functional binding sites, bringing biological utility to ligands that would otherwise be ineffect ive. While some gene-based medicines are also seeking to address undruggable targets, our PROTAC ff targeted protein degraders confer the advantages of traditional small molecule therapies, such as broad tissue distribution, multiple routes of administration, including oral delivery, a well-established development pathway and relative ease of manufacturing. ff We are further diversifying ff our pipeline by developing new PROTACTT targeted protein degraders against ff advantages to existing therapeutic modalities. For targets for which we believe protein degradation offers example, we are pursuing targets for the treatment of neurodegenerative diseases, including tauopathies, which are diseases associated with an aggregation of tau proteins in the brain, such as Alzheimer’s disease. We have engineered PROTACTT targeted protein degraders that, in preclinical studies, have successfully achieved blood brain barrier penetration, a key step in developing drugs with the potential to treat neurodegenerative targets. technology may be advantageous.

We engineer PROTAC protein ff sufferi degraders that are designed to selectively remove disease-causing proteins, and we believe that our proprietary PROTACTT technology is a new therapeutic modality with the potential to provide distinct advantages over existing therapies and to address a broad range of targets, including undruggable proteins. The key elements of our strategy are to: • • • • • Advance clinical development of our lead programs, which address the well-understood oncology targets AR and ER. Our strategy for our PROTACTT platform includes the initial pursuit of oncology targets with well-understood biology, well-characterized disease models and established biomarkers. We are conducting a Phase 2 dose expansion clinical trial for bavdegalutamide and a Phase 1b clinical trial of bavdegalutamide in combination with abiraterone in men with mCRPC; a Phase 2 dose expansion clinical trial for ARV-RR 471 and a Phase 1b cohort expansion for ARV-RR 471 in combination with Ibrance® (palbociclib) in patients with locally advanced or metastatic ER positive / HER2 negative breast cancer; and a Phase 1 dose escalation clinical trial for ARV-RR 766 in men with mCRPC. We believe favorable clinical trial results in these initial oncology programs would validate the broader therapeutic potential of our PROTACTT technology and PROTACTT Discovery Engine. Utilize our PROTAC Discovery Engine platform to address undruggable and difficult-to-drug targets. We are applying our platform to develop treatments forff undruggable targets. Our platform enables us to build PROTAC targeted protein degraders with the potential to degrade these proteins through the cell’s natural protein degradation process using any available binding site, including low-affinit y active binding sites or non-functional binding sites, bringing biological utility to ligands that would otherwise be inactive. We also believe that many “difficult ff apply our PROTAC Discovery Engine. -to-drug” targets, where prior approaches are inadequate, will also provide opportunities to diseases associated with ff Develop new therapeutics with distinct advantages over existing modalities, including gene- based medicines. We intend to address targets forff which we believe protein degradation and the tunable features of our PROTACTT advantages compared to existing targeted protein degraders offer therapeutic modalities. For example, unlike gene-based medicines, our PROTAC targeted protein degraders confer the advantages of traditional small molecule therapies, such as broad tissue distribution, multiple routes of administration, including oral delivery, a well-established development pathway and relative ease of manufacturing. In addition, we have engineered PROTAC targeted protein degraders that, in preclinical studies, have successfully achieved blood brain barrier penetration, creating potential opportunities for our PROTACTT diseases. We also believe there are many other indications for which our technology may be ff advantageous, including autoimmune, anti-infecti technology in neurodegenerative ve and inflammatory conditions. ff Selectively collaborate to realize the full potential of our platform. We are using our PROTACTT Discovery Engine to build an extensive pipeline of product candidates. Our co-development/co- commercialization collaboration with Pfizer has the potential to accelerate and broaden global development and commercialization of ARV-RR 471. In an effoff rt to realize the full potential of our PROTACTT technology, our ongoing strategic collaborations with Bayer, Genentech and Pfizer address targets across multiple therapeutic areas. In addition to these collaborations in human therapeutics, we established a joint venture called Oerth Bio LLC, or Oerth, with Bayer to pursue our PROTACTT collaborations with leading biopharmaceutical companies with specialized capabilities or know-how, including global development and commercial expertise and capabilities for those products for which we retain full development and commercialization rights. We believe this selective approach to collaboration will further broaden the therapeutic reach of our PROTAC technology, as well as complement and expand our internal development expertise. technology in agricultural applications. We plan to continue to selectively pursue Continue to expand the capabilities of our PROTAC Discovery Engine and the breadth of our intellectual property portfolio. We are investing in our research and development activities to expand the capabilities of our PROTACTT Discovery Engine and the breadth of our intellectual property portfolio. This includes: research into novel E3 ligases, key proteins in the ubiquitin proteasome system, that may have tissue-specific or disease-specific features; the discovery of novel binding ligands; the discovery of orally bioavailable and blood brain barrier penetrant 7 composition of matter in the United States and other countries for PROTAC protein degraders; and improvement of our PROTAC targeted protein degrader design and optimization processes.

Our Focus The Role of Proteinsii in Disease Human cells produce tens of thousands of differe ff nt proteins, the entirety of which is referred to as the proteome. Proteins are responsible forff many structural, functional and regulatory processes in cells. 8 Proteins are large, complex biomolecules made through a series of steps based on instructions carried from DNA, the genetic “blueprint” within the cell. Generally, sequences of DNA are converted into messenger ribonucleic acid, or mRNA, during a process called transcription. mRNA provides the template that specifies the assembly of a particular sequence of amino acids into proteins during a process known as translation. The amino acid sequence dictates, among other things, the conformat ion, or 3-D shape, of the resulting protein. Proteins can have complex shapes, with multiple chains of amino acids folding together in some cases to reach a final form. The final form of the protein, as well as the timing, location and concentration of its expression within the cell, is essential to the protein’s intended function. ff In healthy cells, the transcription and translation processes contribute to producing properly folded proteins in the right amounts and at the correct times to ensure normal cell health and function. This balance can be disrupted by a variety of events and factors, such as cellular stress, genetic mutations and transcriptional or translational errors, which can then lead to cellular overexpression, abnormal production rates, misfolding or mutations of proteins. When proteins are overexpressed or mutated, a wide variety of diseases can result. For example, it is well documented that overexpression of androgen receptor, a nuclear hormone receptor, is implicated in prostate cancer. Similarly, overexpression of estrogen receptor is known to be associated with breast cancer. In neurodegenerative diseases, abnormal deposition of misfolded or aggregated proteins in the brain, including the intraneuronal aggregation of the microtubule-associated protein tau, are associated with Alzheimer’s disease. Recent genomic advances continue to implicate the role of specific proteins in many disease states. There are multiple therapeutic approaches, both approved and in development, to treat diseases caused by abnormal proteins or aberrant protein expression. Each operates at a differen the protein, as illustrated in the following graphic: ff t point in the lifecycle of Small Molecule InhII ibitors, Gene Therapy rr and Gene Editing Traditional small molecules seek to block or inhibit the expression or function of an errant protein. While there are numerous examples of safe and effective small molecule therapies, their effiff cacy can be limited by weak or incomplete binding of the therapeutic molecule to the relevant binding site on the protein, the cell’s ability to counteract the inhibitory effeff ct of the drug by producing more of the protein, mutation of the target, or evolution of the cell to rely on alternate pathways.

In the case of CRISPR/Cas9, the resulting modification of the gene gene editing and gene silencing approaches ff Protei rr n Dii egradatiodd n When proteins become old, mutated, misfolded or simply have served their purpose, they are naturally degraded by the body through the ubiquitin proteasome system in which cells mark or tag a particular protein for disposal by attaching several molecules of the small regulatory protein ubiquitin to the protein to be disposed. This process generally proceeds along the following steps in rapid sequence: • • The E1 enzyme activates ubiquitin, which is then transferred to an E2 enzyme. An E3 ubiquitin ligase, or E3 ligase, transfers the ubiquitin from the E2 enzyme to a specific target protein. • Once a chain of at least four ubiquitins are attached to the target protein, the proteasome recognizes the polyubiquinated protein. • The proteasome breaks down or degrades the protein into its amino acid components. Several therapeutic approaches work at the protein level by modulating the ubiquitin proteasome system to harness the cell’s natural protein disposal system to degrade and remove a protein. Degradation can be induced by inhibiting chaperone molecules such as HSP90, which are known to facilitate correct protein folding, resulting in tagging misfolded proteins for degradation. HSP90 inhibitors, however, have shown limited efficaff cy in the clinic to date. Some degraders use an approach that causes a conformff ational change in a specifically targeted ed protein, which triggers the cell’s innate protein degradation system to dispose of protein, resulting in a misfoldff the misfolded protein. Although these compounds have shown efficacy those proteins able to adopt a non-native state, leaving a wide array of protein targets unaddressed. The only currently marketed protein degrader utilizing this mechanism, the breast cancer therapy fulvestrant, requires intramuscular administration, further limiting its convenience and pharmacokinetic profile. , they only induce the degradation of ff Chimeric small molecules use a diffeff rent protein degradation approach. Instead of causing improper folding or inhibiting molecules that facilitate proper folding of the target protein, chimeric small molecules directly recruit an E3 ligase to tag specifically targeted proteins with ubiquitin, signaling the proteasome to degrade the targeted protein. Our PROTACTT targeted protein degraders take this approach to protein degradation. PROTACTT Targeted rr Protein rr Degradersdd — Our Approach rr rr to Protei n Dii dd egradation We have engineered our PROTACTT targeted protein degraders to utilize the cell’s naturally occurring targeted protein degraders are chimeric small molecules with two operative ends—one, protein disposal system, directing the proteasome to recognize and degrade specific proteins associated with disease.

We continue to research additional E3 ligases that are expressed in specific tissues or diseases, and identify or discover associated binding ligands, to create novel PROTAC protein degraders that recruit E3 ligases with targeted expression patterns, such as tumor or central nervous system-localized E3 ligases, that may be beneficial for the development of targeted cancer and neurologic therapies.

Turning Degraders into Drugs • • Arvinas Rules - Optimization of traditional small molecule agents tends to focus on guidelines that increase the chances of such molecules having sufficient permeability and solubility to make them orally bioavailable. Chimeric small molecules, including our PROTAC targeted protein degraders, are larger than traditional small molecule therapeutics, such that the conventional optimization parameters prevalent in traditional drug discovery do not readily apply. As such we have developed and apply our own proprietary Arvinas Rules for our PROTACTT targeted protein degraders. Through our Arvinas Rules, we have made PROTAC targeted protein degraders that are orally bioavailable and that cross the blood brain barrier. ff Deep knowledge of in vivo PK/PD and efficacy relationships - Our understanding of molecular features that impact PROTACTT create PROTACTT to rapidly progress from target identification to PROTACTT degraders with drug-like properties and activities.

We have harnessed these features to successfully target and degrade a wide range of protein classes, including nuclear proteins, transcription factors, epigenetic modulators, membrane proteins, cytosolic proteins and high molecular weight neuroprotein aggregates. Potency The potency of our PROTACTT technology is driven by two key characteristics: the iterative mechanism of our PROTACTT targeted protein degraders and the ability to turn weak binders into potent degraders. Iterativett Mechanism Our PROTACTT targeted protein degraders behave iteratively to repeatedly induce the ubiquitination and targeted subsequent degradation of proteins. As a result, protein degradation may be observed with PROTACTT protein degrader concentrations much lower than those required for typical small molecule inhibition, even operating at picomolar concentrations. We expect that the high cellular potency of PROTACTT degrader could provide the possibility of removal of proteins at levels equivalent to the knock out effect by gene-based medicines currently being explored. Our PROTACTT significant therapeutic advantages, including low doses, low drug exposures and practical dosing intervals, potentially mitigating toxicity and tolerability risks. targeted protein degraders offer ff potentially targeted protein ff intended The iterative mechanism of our PROTACTT targeted protein degraders potentially leads to more complete and lasting inactivation of downstream signaling in cells. In oncology, this translates into improved inhibition of tumor cell growth and reduces the likelihood of cell compensation through activation of alternative proteins, a targeted protein degraders to common risk associated with small molecule inhibitors. This enables PROTACTT operate in a broad therapeutic space between desired degradation-induced pharmacology and unwanted inhibition-induced effect s. ff Once the pre-existing reservoir of the targeted protein is depleted, our PROTACTT targeted protein degraders only need to degrade newly resynthesized protein to maintain their effect. resynthesis rate of the protein, this may be achievable with low tissue concentrations of PROTACTT protein degrader, which could lead to safety benefits and opportunities for flexible dosing regimens. Depending on the ff targeted ii Weak Binders Become Potent Degraders Using our platform and know-how, we are able to engineer potent PROTAC targeted protein degraders that do not require a high degree of binding strength to their targets. This contrasts with small molecule inhibitors, which require strong binding to a target protein and function by continually occupying the protein’s active site. The potency of our PROTAC targeted protein degraders is determined by a number of kinetic factors: formation of the trimer complex, rapid ubiquitination, trafficking proteasome and release of the PROTACTT degradation. As a result, a PROTACTT maintain a deep and prolonged suppression of protein levels, leading to the desired pharmacological effect. This provides opportunities to use our PROTAC technology to repurpose small molecules that only weakly bind to their target to create potent degraders as PROTACTT targeted protein degrader with a low level of target protein occupancy can targeted protein degrader to enter another iterative cycle of of the ubiquitinated target to the targeted protein degraders. ff ff 13 For example, we have published experiments where we built PROTACTT targeted protein degraders from tinib-based PROTACTT 1, which happened to further weaken the binding affinit ity is measured by KD, or equilibrium dissociation constant.

The decreasing presence of the p38α protein is depicted by a lighter shade of the p38α band in the western blot as the doses of the PROTAC 1 increase. This demonstrates our ability to use a weak binder to create a potent PROTAC targeted protein degrader. Based on our experience, we believe that with additional medicinal chemistry effoff targeted protein degrader could be further increased. better than its binding strength. The figure below shows a western ity relative to foretinib, decreasing from 1 micromolar, or μM, to 11 rt, the degradation potency of this weak-binding PROTAC 1 achieved potent degradation of p38α with a inib, the PROTAC 1, and an inactivated y to p38α.

For example, we have demonstrated degradation of abnormal, but not wild-type, forms of the BRAF protein using a PROTACTT outside the cell to the cell’s nucleus and is part of a pathway that regulates cell proliferation, different migration and apoptosis. Mutations of BRAF, however, have been associated with a number of different cancers. As shown in the figure below, our PROTACTT depicted by a lighter shade in the columns labeled 300 nM, representative of each of the three classes of BRAF mutations, while not degrading the wild-type BRAF, as depicted by an unchanging shade in each of the columns shown on the western blot. targeted protein degrader.

The multiple routes of delivery for our PROTACTT example, oral delivery can offer approaches such as gene-based medicines that allows for more convenient treatment.

The figure below depicts a structural model of the Abl tyrosine kinase. This protein kinase possesses an enzymatic active site that is inhibited by the marketed small molecule, imatinib. The Abl kinase also has a second, non-functional active site, called an allosteric site, in its structure that can bind a diffeff rent small molecule, named GNF-2, which despite binding allosterically (with a relatively weak KD of 500 nM), inhibits only the wild type protein (C-Abl), but not BCR-Abl-a mutated form of Abl implicated in chronic myelogenous leukemia.

Bavdegalutamide demonstrated activity in preclinical models of AR overexpression and AR mutations, both common mechanisms of resistance to current standard-of-care agents in men with prostate cancer. We believe that the different bavdegalutamide, including its iterative activity, has the potential to translate into significantly improved clinical outcomes over current standard-of-care iated PROTAC pharmacology of agents. ff ff ff Prostate rr Cancer In the United States, prostate cancer is both the second most prevalent cancer in men and the second leading cause of cancer death in men. Current estimates predict that one in nine men will be diagnosed with prostate cancer in his lifetime. The American Cancer Society estimates that in 2022 there will be over 268,000 new cases of prostate cancer in the United States and approximately 34,500 deaths from the disease. Men with mCRPC have a poor prognosis and a predicted survival rate of fewer than two years from the initial time of progression. Treatment options for prostate cancer depend on many different ff factors, including the stage of the cancer. Castration-resistant prostate cancer is defined by disease progression despite androgen deprivation therapy, or ADT, aTT nd is oftenff indicated by rising levels of PSA. In making treatment evaluations, physicians monitor disease burdens in several ways, including changes in PSA levels. Increased PSA blood levels are considered by many physicians as indicative of cancer progression, and alternative treatment options may be considered. Current standard of care for men with castration-resistant prostate cancer provides that patients should initially receive a combination of ADT and either abiraterone, which works by decreasing androgen levels, or enzalutamide, which works by blocking androgen binding to AR. If the disease progresses despite these second-generation hormonal therapies, chemotherapy is considered the next treatment option. Treatment with chemotherapy is generally postponed for as long as possible due to the potential for severe side effects including neuropathies, nausea, diarrhea, decreased mental capacity and increased risk of infections. ff ff Androgen receptor remains the principal driver of castration-resistant prostate cancer progression during the transition from localized to metastatic disease, with AR gene amplification occurring in 40% to 60% of patients, amplification of a transcription regulatory region upstream of the AR gene occurring in 70% to 87% of patients, and AR point mutations occurring in approximately 15% of patients. Between 15% to 25% of patients do not respond to either abiraterone or enzalutamide and the vast majorit ultimately become resistant, resulting in limited survival. There remains meaningful unmet medical need in the treatment paradigm of mCRPC, including a significant underserved set of patients who are or become resistant to current therapies. Based on our preclinical data, we believe our PROTAC targeted protein degraders may overcome these known resistance mechanisms and create meaningful clinical benefit for patients. y of the responsive patients will a Preclinicii al Development We have conducted a comprehensive preclinical program to study bavdegalutamide as a potential treatment forff men with mCRPC. In in vitro models, bavdegalutamide degraded 95% to 98% of AR in multiple cell lines typically used in prostate cancer research. 17 Bavdegalutamide is also highly selective for AR. A proteomic analysis of VCaP cells treated in vitro with bavdegalutamide at a 10 nM concentration for eight hours demonstrated that only AR was degraded from the nearly 4,000 measured proteins. Importantly, in addition to AR degradation and selectivity, we have observedrr in preclinical studies the ability of bavdegalutamide to potently inhibit prostate cancer cell growth and reduce PSA levels. In addition to guiding treatment decisions, reduction in PSA is often an indicator of the effect iveness of treatment in clinical trials, however, it is not recognized as a surrogate endpoint for purposes of regulatory approval. For example, bavdegalutamide demonstrated equivalent reduction in PSA to enzalutamide at ten-fold lower concentration levels in an in vitro inhibition study of PSA synthesis in Lymph Node Cancer of the Prostate cells, which are androgen-sensitive human prostate adenocarcinoma cells, that have been engineered to overexpress AR. ff In in vivo mouse models, bavdegalutamide has inhibited AR-dependent tumor growth in a statistically significant manner. Bavdegalutamide exhibited superior tumor growth inhibition compared to enzalutamide in both castrated and intact (non-castrated) xenograft mff odels derived from VCaP cell lines. To assess the ability of bavdegalutamide to treat enzalutamide-resistant cancers, we conducted in vivo odel. These VCaP tumors acquired studies of bavdegalutamide in an enzalutamide-resistant VCaP xenograft mff resistance to enzalutamide after being continuously propagated in castrated, enzalutamide treated mice for approximately three years. This resistance can be seen in the figure below, as tumors in mice dosed with enzalutamide grew at nearly the same rate as tumors in mice dosed only with the drug vehicle - a control similar to dosing a placebo. Orally delivered bavdegalutamide significantly inhibited tumor growth, described as tumor growth inhibition, or TGI, in these enzalutamide-resistant VCaP tumors.

We conducted an in vivo study using a tumor line derived directly from a patient, referred to as a patient derived xenograft,ff or PDX, model. This model is derived from a tumor from a patient not treated with enzalutamide but that is insensitive to enzalutamide. This insensitivity can be seen in the figure below, as tumors in mice dosed with enzalutamide grew at only a slightly slower rate than tumors in mice dosed only with the drug vehicle. In contrast, orally delivered bavdegalutamide significantly inhibited tumor growth in these enzalutamide-insensitive tumors, achieving a TGI value of 100%. Further, PSA levels in the plasma of mice following 20 days of 18 bavdegalutamide dosing significantly decreased in comparison to those dosed with only the drug vehicle or enzalutamide.

We conducted investigational new drug, or IND,-enabling Good Laboratory Practice, or GLP, toxicology studies with bavdegalutamide in rats and dogs to support advancement of bavdegalutamide into clinical development. Both study designs called for animals to be treated once daily, orally for 28 days, followed by a 14-day recovery period for high dose animals. We believe both studies provide favorable safety margins of approximately five to ten times higher than the anticipated therapeutic doses. In the rat study, a no observed adverse effect ff level, or NOAEL, of 40 milligrams per kilogram, or mpk, the mid-dose, in female animals and 120 mpk, the high dose, in male animals was identified. All findings observed in male high-dose animals were considered reversible by the study director. Atrophy of the prostate and seminal vesicles was noted in male animals at all dose levels and we believe is attributable to the pharmacologic activity of bavdegalutamide. In the dog study, the NOAEL was 10 mpk per day, the mid-dose. The high dose of 30 mpk per day exceeded the maximum tolerated dose, and dosing in this group was stopped prior to the planned completion to allow for collection of reversibility data. Elevations in liver function enzymes noted in some mid- and high-dose animals were considered reversible by the study director, and non-adverse as they were without microscopic correlates. In addition, at all dose levels, including animals receiving vehicle only, gastrointestinal alteration such as loose and abnormally colored stools were noted. Decreased prostate weights were noted in all male animals and we believe are attributable to the pharmacologic activity of bavdegalutamide. Our Phase 1/2 Clini ii cal Trial rr In 2019, we initiated dosing in a Phase 1 clinical trial of bavdegalutamide. Our Phase 1 trial is designed as an open label, dose-escalation study of bavdegalutamide in men with mCRPC whose disease has 19 progressed on at least two prior systemic therapies, one of which must have been enzalutamide or abiraterone. The Phase 1 trial is designed to primarily investigate the safety and tolerability of bavdegalutamide. Secondary endpoints include characterization of bavdegalutamide’s pharmacokinetic profile and preliminary assessment of biochemical and clinical activity based on evaluation of PSA levels, and radiographic measurement of evaluable lesions. The anti-tumor effect Evaluation Criteria in Solid Tumors, or RECIST, a standardized set of rules for response assessment based on tumor shrinkage which is widely used in oncology clinical trials. We also will evaluate exploratory markers of disease burden, such as circulating tumor cell enumeration, as exploratory endpoints of the trial. s of bavdegalutamide in measurable lesions will be assessed using Response ff A potential drug-drug interaction between bavdegalutamide and rosuvastatin, or ROS, was identified during the trial. One patient receiving 280 mg bavdegalutamide experienced a Grade 4 dose-limiting toxicity of elevated aspartate transaminase/alanine transaminase, or AST/AL// T,LL liver enzymes followed by acute renal failure. The second patient, receiving 70 mg bavdegalutamide, experienced a Grade 3 AST/ALT elevation, which resolved after the removal of ROS, and the patient was retreated with bavdegalutamide. Follow-up exploratory findings indicate that ROS concentrations, but not bavdegalutamide concentrations, were elevated in both patients who had liver function test increases. Subsequent in vitro transport pump studies indicated that bavdegalutamide inhibited breast cancer resistant pump transporter, of which ROS is a substrate. Following the initial data that supported a potential interaction with ROS, concomitant use of ROS was precluded.

We reported that bavdegalutamide showed reduced PSA levels of greater than or equal to than 50%, or PSA50, in 46% of the 28 patients with tumors harboring AR T878X/H875Y (T878X = T878A or T878S) mutations. These results also demonstrated PSA declines and tumor regressions in patients without tumors harboring AR T878X/H875Y mutations, suggesting an opportunity to develop bavdegalutamide more broadly in prostate cancer. As of the data cut-off date, 195 patients were enrolled across the Phase 1/2 clinical trial (71 in Phase 1; 124 in Phase 2). The Phase 1 dose escalation trial evaluated bavdegalutamide at doses ranging from 35–700 mg, once- daily, or 210–420 mg twice-daily, in patients with mCRPC and two or more prior therapies (including abiraterone and/or enzalutamide). Patients in the ongoing ARDENT study are enrolled in one of four subgroups: patients with tumors with AR T878X and/or H875Y mutations and excluding AR L702H mutations and AR-V7 splice variants; patients with tumors with wild-type AR or AR alterations other than T878X, H875Y, LYY 702H, AR-V7; patients with tumors with AR L702H mutations or AR-V7 splice variants, which are variants of AR that bavdegalutamide did not degrade preclinically; and patients with biomarker agnostic tumors with only one prior novel hormonal agent, or NHA, and no prior chemotherapy. ff The ARDENT Phase 2 dose expansion trial is administered at a starting recommended Phase 2 dose, or RP2D, of 420 mg, once-daily. Patients in the ARDENT trial received a median of four prior lines of therapy with 100% receiving at least one NHA (64% abiraterone, 75% enzalutamide or other AR inhibitor, 39% both abiraterone and an AR inhibitor) and 31% receiving at least one chemotherapy regimen. 20 Efficacy Measures We presented efficaff cy measures on a combined basis for patients in both the completed Phase 1 dose escalation trial and the interim analysis from the ongoing ARDENT Phase 2 dose expansion trial. In the biomarker defined (“more pretreated”) subgroups, we observed the following: • • • In eight patients with tumors with AR T878X and/or H875Y mutations but excluding other AR variants, PSA50=75%; PSA decline of more than 30%, or PSA30, =75% In 44 patients with tumors with wild-type AR or AR alterations other than T878X, H875Y, LYY 702H, or AR-V7, PSA50=11%; PSA30=20% In 25 patients with tumors with AR L702H or AR-V7, PSA50=4%; PSA30=20% In the biomarker agnostic (“less pretreated”) subgroup comprising 27 patients with no more than one prior NHA and no prior chemotherapy, the PSA50 response rate was 22% and the PSA30 response rate was 26%. In biomarker-evaluable patients treated at or above the RP2D and with tumors harboring AR T878X/ H875Y mutations (across all subgroups and thus regardless of prior therapy regimens or other mutations; n=28), the PSA50 response rate was 46% and the PSA30 response rate was 57%. Of seven RECIST-evaluable patients across the Phase 1 and Phase 2 trials with tumors harboring AR T878X/H875Y mutations, two had confirmed durable partial responses. These patients were on treatment for approximately nine months (ongoing as of the data cut-off)ff and ten months; the duration of treatment ranged from eight weeks to 44 weeks, with three of the seven patients continuing on treatment as of the data cutoff off December 20, 2021. f Twelve (43%) of the 28 patients with AR T878X/H875Y-posit YY ive mutations received bavdegalutamide for 24 weeks or more, with nine patients ongoing as of the data cutoff.ff PSA reductions and evidence of anti-tumor activity as measured by RECIST were observed across all subgroups regardless of mutation status, including tumors not harboring AR T878X/875Y mutations. RECIST responses were seen in patients with tumors lacking AR T878X/H875Y mutations (one confirmed and three unconfirmed RECIST responses). The “less pretreated” subgroup (n=27) had a similar molecular profile—as assessed by circulating tumor DNA analysis—to the more pretreated, biomarker-defined subgroups in the ARDENT trial. These similarities included both AR variations (point mutations and AR-V7 splice variants) and non-AR mutations frequently associated with poor outcomes (e.g., TP53, BRCA1). Six of the 27 patients (22%) had PSA50 reductions, and this PSA50 rate was similar to that observed collectively in the “more pretreated” subgroups (16%; n=77). Four of the six “less pretreated” patients with PSA50 declines had tumors with AR T878X/H875Y mutations. Safety at nd Tolerability Bavdegalutamide had a manageable tolerability profile at the RP2D. The majority of treatment-related adverse events, or TRAEs, were Grade 1/2 and there were no Grade 4 or greater TRAEs in the 138 patients treated at the RP2D. TRAEs that occurred in 10% or more of patients treated at the RP2D were nausea (Gr 1: 30%; Gr 2: 16%; Gr 3: 1%), fatigue (Gr 1: 23%; Gr 2: 12%; Gr 3: 1%), vomiting (Gr 1: 20%; Gr 2: 5%; Gr 3: 1%), decreased appetite (Gr 1: 14%; Gr 2: 11%; Gr 3: 1%), diarrhea (Gr 1: 14%; Gr 2: 4%; Gr 3: 2%), alopecia (Gr 1: 13%; Gr 2: 1%; Gr 3: N/A)// AST increased (Gr 1: 9%; Gr 2: 3%; Gr 3: 1%), weight decreased (Gr 1: 7%; Gr 2: 5%; Gr 3: 0%), and anemia (Gr 1: 4%; Gr 2: 1%; Gr 3: 5%). TRAEs at the RP2D led to dose reduction in 11 (8%) patients and discontinuation in 12 (9%) patients. In the first half of 2022, we intend to initiate discussions with the FDA about the potential for an accelerated approval pathway with bavdegalutamide in molecularly defined mCRPC and finalize a partnership for a companion diagnostic. In the second half of 2022, we plan to initiate a pivotal trial evaluating 21 bavdegalutamide in patients with mCRPC who have progressed on or after tumors that harbor AR T878X/H875Y tumor mutations. We anticipate that future studies will be planned to explore the potential to treat earlier-line patients with AR-dependent tumors who may benefit from bavdegalutamide therapy. novel hormonal agents and have ff VV ARV-766 TT for the Treatmen t of Men with Metastatic Castration-Resistan ii t Prostate PP Cancer We are developing ARV-RR 766 to target and degrade wild-type and mutated AR including at least one additional, clinically relevant AR point mutation, the L702H point mutation, which bavdegalutamide did not degrade in preclinical studies. The L702H point mutation in the ligand-binding domain of AR results in activation of the AR by glucocorticoids and can cause resistance to a standard of care regimen. Recent studies have reported that between approximately 2-9% of patients with mCRPC had an L702H point mutation. We initiated a Phase 1 dose escalation clinical trial in 2021. In the second half of 2022, we plan to present Phase 1 dose escalation data and initiate a Phase 2 expansion trial for the treatment of men with mCRPC. Next Generation AR Degradersdd We are developing additional PROTAC targeted protein degraders capable of degrading certain AR a dimer with a full-length AR, and such non-identical protein dimers are splice variants. We expect that results from our Phase 1/2 clinical trials of bavdegalutamide and ARV-RR 766 will provide further data on the role of androgen receptor splice variant-7, or AR-V7, in prostate cancer. Bavdegalutamide and ARV-RR 766 bind to full-length AR at its ligand-binding domain. AR-V7 is a truncated form of AR that lacks the ligand-binding domain necessary to bind with bavdegalutamide and ARV-RR 766 and which bavdegalutamide and ARV-RR 766 therefore do not degrade. AR functions as a dimer, a complex made up of two individual AR proteins. AR-V7 can formff called heterodimers. We believe that bavdegalutamide and ARV-RR 766, by degrading the full-length AR component of the heterodimer, could successfully inactivate AR-V7-directed signaling. Although shown to form a heterodimer preclinically, there is uncertainty as to whether AR-V7 and AR form a heterodimer in patients’ tumors. It is also possible that AR-V7 signals through V7-only dimers, which would be unaffecte bavdegalutamide and ARV-RR 766. Although the presence of AR-V7 has been shown to correlate with a lack of response to enzalutamide and abiraterone, a published study demonstrated that approximately 40% of patients with AR-V7 expressing circulating tumor cells show a PSA response to enzalutamide. Given the evolving potential role of AR-V7 in prostate cancer, as a follow-on to bavdegalutamide and ARV-RR 766, we are exploring the identification and development of a PROTACTT well as other AR splice variants. targeted protein degrader that can degrade AR-V7 directly, as d by ff VV ARV-471 reast Cancer Negative Bvv TT for the Treatmen t of Patients with Locallyll Advanced or Metastatic ER PEE ositive / HER2H We are developing ARV-RR 471, an orally bioavailable ER degrading PROTACTT targeted protein degrader, as an alternative to, and potentially more potent degrader than, the intramuscular injection fulvestrant and other selective ER degraders currently in development for the treatment of patients with locally advanced or metastatic ER positive / HER2 negative breast cancer. Similar to our AR program, we have chosen ER degradation as a therapeutic focus given the well-documented biology of ER signaling as a principal driver in a high percentage of breast cancers. ARV-RR 471 has demonstrated activity in ER positive breast cancer preclinical models. We are clinically investigating ARV-RR 471 for use as a single agent and in combination with cyclin- dependent kinase, or CDK, 4/6 inhibitors such as palbociclib. We believe ARV-RR 471 has the potential to improve clinical outcomes over current standards of care for patients with locally advanced or metastatic ER positive / HER2 negative breast cancer. Breast Cancer In the United States, breast cancer is the second most common cancer and the second leading cause of cancer death in women. The American Cancer Society estimates that in 2022 there will be approximately 288,000 women diagnosed with invasive breast cancer in the United States. Metastatic breast cancer accounts for approximately 6% of newly diagnosed cases. Approximately 80% of newly diagnosed breast cancers are ER+, with many patients developing resistance to current treatment options over time. 22 Treatment options for breast cancer depend on many different ff factors, including the stage of the cancer and whether the cancer cells contain hormone receptors. Patients with locally advanced or metastatic breast cancer are treated with systemic therapy, including hormone therapy, chemotherapy and targeted therapy, either as single-agents or in combination. Patients with locally advanced or metastatic ER positive / HER2 negative breast cancer are often treated with hormone therapy, such as tamoxifen or an aromatase inhibitor, sometimes in combination with targeted drugs such as CDK4/6 inhibitors. In patients with aggressive disease or whose disease continues to progress with a hormonal treatment regimen, chemotherapy may be prescribed. Treatment with chemotherapy is generally postponed for as long as possible due to the potential for severe side effects including neuropathies, nausea, diarrhea, decreased mental capacity and increased risk of infections. ff A current standard of care for patients with ER positive / HER2 negative locally advanced or metastatic breast cancer is fulvestrant, an ER degrader administered as a monthly intramuscular injection, either as a single-agent or in combination with another targeted therapy. While fulvestrant has validated the importance of ER degradation as a therapeutic intervention, up to 50% of ER can remain when compared to baseline levels after six months of treatment with fulvestrant, providing an opportunity forff more potent ER degraders, such as ARV-RR 471, our PROTACTT targeted protein degrader. rr Precl inll ical Development We have conducted a comprehensive preclinical program to study ARV-471 VV as a potential treatment forff patients with locally advanced or metastatic ER positive / HER2 negative breast cancer. In our preclinical studies, ARV-RR 471 was a superior degrader of ER compared to fulvestrant.

ARV-RR 471 reduced ER by 85%, on average, at 10 mpk as compared to the control tumors and by 89%, on average, at 30 mpk as compared to the control tumors. We have also conducted preclinical studies to test ARV-RR 471 in a PDX model. This model is derived from ff a tumor with an ESR1 mutation (Y537S), which is a mutation in the ER that occurs in patients who have been agents such as tamoxifen or an aromatase inhibitor, such as letrozole, and has treated with standard-of-care been cited as a mechanism of resistance to those drugs. These studies included a comparison with fulvestrant. In this 28-day dosing study, oral ARV-RR 471 inhibited tumor growth by 99% at the 10 mpk dosing level and by 106% at the 30 mpk dosing level which was observed to be superior at both dosing levels to a clinically relevant was shown to reduce ER by 79% and 88% at the 10 mpk and dose of 200 mpk of fulvestrant.

VV We have also conducted studies of ARV-RR 471 in combination with palbociclib, a CDK4/6 inhibitor that is standard of care when used together with fulvestrant.

Our Phase 1/2 Clini ii cal Trial rr In August 2019, we initiated dosing in a Phase 1 clinical trial for ARV-RR 471. The trial is an open-label dose-escalation study in which we expect to dose approximately 28 to 36 patients with locally advanced or metastatic ER positive / HER2 negative breast cancer who have progressed on at least two prior endocrine therapy regimens and a CDK4/6 inhibitor. Eligible patients may have also received up to three prior regimens of cytotoxic chemotherapy. The protocol provides for a starting dose of 30 mg/day, administered orally. In the ffirst an fd fourt ff h quarters fof 2020, we amended the protoco fl forff our Phase 1 clinical trial ffor AARV-RR 471, to include the Phase 2 expansion cohort and a Phase 1b cohort expansion of ARV-RR 471 in combination with Ibrance® (palbociclib), respectively. The dose escalation portion of our Phase 1/2 clinical trial of ARV-RR 471 is designed to assess safety, tolerability and pharmacokinetics, or PK, of ARV-471 breast cancer, as well as measures of anti-tumor activity as secondary endpoints. VV in patients with locally advanced or metastatic ER+/HER2- 24 In December 2021, we announced updated data, as of the data cut-off dff ate of September 30, 2021, from the dose escalation portion of our Phase 1/2 clinical trial. Enrolrr lmll ent As of the data cut-off dff ate, 60 adult patients with locally advanced or metastatic ER+/HER2- breast cancer were treated in the Phase 1 dose escalation portion of the trial with total daily ARV-RR 471 doses ranging from 30 mg to 700 mg. This patient group is heavily pretreated, with a median of four prior therapies. All patients were previously treated with CDK4/6 inhibitors; 80% of patients received prior fulvestrant; and 78% received prior chemotherapy. Efficac yc ff Of 47 patients who were evaluable forff clinical benefit (confirmed complete response, partial response, or stable disease ≥ 24 weeks) the clinical benefit rate was 40%. As of the data cutoff dff ate, 14 patients were continuing to receive study treatment, including two patients who had been on treatment for over 18 months. Three confirmed partial responses were observed among the 38 patients with baseline RECIST measurable disease and at least one on-treatment tumor assessment. Safetyt Patients were treated in the monotherapy escalation at total daily doses of 30 mg (n=3), 60 mg (n=3), 120 mg (n=7), 180/200 mg (n=11), 360 mg (n=15), 500 mg (n=17), and 700 mg was administered twice a day (300 mg in the morning / 400 mg in the evening) (n=4). A maximum tolerated dose was not reached and no dose limiting toxicities or Grade 3 or 4 treatment-related adverse events, or TRAEs, were observed. Of the 60 patients, 37% had Grade 1 TRAEs and 57% had Grade 2 TRAEs, and the most common TRAEs were nausea (29%), fatigue (20%), and vomiting (10%). No Grade 1 or 2 TRAEs led to discontinuation or dose reduction of ARV-RR 471. Four patients experienced six Grade 3 TRAEs that were potentially related to ARV-RR 471, including: headache lasting 1-day, single occurrence of asymptomatic increased amylase and lipase, nausea and asymptomatic QTc pTT rolongation, and post-biopsy venous embolism. The patient with the venous embolism was the only Grade 3 patient who discontinued ARV-RR 471 due to a TRAE, and the patient with Grade 3 nausea was the only patient with a dose reduction due to a TRAE (reduced from 500 mg to 400 mg daily). ER Degradat rr iontt In paired biopsies from 14 patients across all doses up to 500 mg daily, robust ER degradation of up to 89% was observed, regardless of ESR1 mutation status. Median and mean ER degradation across dose levels were 67% and 64%, respectively. Pharmacokinetics ARV-RR 471 demonstrated a dose-related increase in plasma exposure, with doses from 30 mg to 500 mg daily, resulting in steady-state exposure levels that exceeded the exposure associated with tumor regression in preclinical breast cancer models. Mean exposure on day 15 exceeded the nonclinical efficacious of 60 mg or more daily. range at doses ff ARV-RR 471 currently is being evaluated as a treatment forff metastatic breast cancer in a Phase 1 dose escalation study, a Phase 1b combination study with IBRANCE® (palbociclib), and a Phase 2 monotherapy dose expansion study.

Other Oncology,gg Immuno-Oncology and Undruggable TargTT ets We have active preclinical programs to evaluate additional established targets in oncology and immuno- oncology, as well as other currently undruggable targets. In line with our strategy, we assess potential exploratory programs on a target-by-target basis to decide whether our PROTAC targeted protein degraders provide a compelling differentiated approach over standard-of-care or other, existing or potential competing mechanisms of action directed against a specific target. In the case of currently undruggable targets, we assess whether the features of our PROTAC targeted protein degraders, including their potential to degrade proteins via sites other than enzymatic active sites and the ability to initiate the degradation process using only weak binders, offer us opportunities to degrade those targets. ff ff Our exploratory and research activity in oncology and immuno-oncology includes programs directed to the B-cell lymphoma 6 protein (BCL6), a transcription factor implicated in B cell lymphomas; Kirsten rat sarcoma (KRAS), an oncogenic cell growth regulator; Myc, an oncogenic transcription factor driving tumor cell proliferation; and hematopoietic progenitor kinase 1 (HPK1), a suppressor of T cell activation. Neurodegenerative Diseases ff a rapidly growing patient population and represent one of the largest unmet medical Neurodegenerative diseases are generally progressive in nature and result in the degeneration and often death of neurons in the brain, leading to cognitive decline, functional impairment and eventually death. These diseases affect needs of our time. Alzheimer’s and Parkinson’s diseases encompass the largest patient populations among the neurodegenerative diseases. The Alzheimer’s Association estimated that 6.2 million Americans aged 65 and older were living with Alzheimer’s dementia in 2021, and the Parkinson’s Foundation estimated that nearly one million Americans are living with Parkinson’s disease. Alzheimer’s disease is marked by the progressive accumulation of aggregated tau protein, while aggregation of alpha-synuclein is thought to cause Parkinson’s disease. Inhibitor-based therapies targeting the proteins thought to be the cause of these neurodegenerative diseases have failed to show clinically meaningful benefit to date.

We have demonstrated that tau PROTAC protein degrader molecules could be dosed peripherally and degrade pathogenic tau in the brain of a mouse tauopathy model. In preclinical studies, we have demonstrated that alpha-synuclein PROTAC degraders can specifically degrade aggregated forms of the protein. We have conducted in vitro experiments in cells expressing the A53T mutant form of alpha-synuclein, a mutation that causes aggregation of alpha-synuclein and early-onset Parkinson’s diseases in patients. We treated these cells with alpha-synuclein targeting PROTAC degraders at 1 μM forff 48 hours. In addition to our tau and alpha-synuclein programs, our neuroscience programs include a program directed to mutant huntingtin (mHTT), a key protein target for Huntington’s disease.

In the United States, the term of a patent covering a drug approved by the U.S. a patent term extension under the Hatch-Waxman Food and Drug Administration, or FDA, may be eligible forff Act as compensation for the loss of patent term during the FDA regulatory review process. The period of extension may be up to five years beyond the expiration of the patent but cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval. Only one patent among those eligible forff an extension may be extended. Similar provisions are available in Europe and in certain other jurisdictions to extend the term of a patent that covers an approved drug. It is possible that issued U.S. patents covering bavdegalutamide and ARV-RR 471 may be entitled to patent term extensions. If our product candidates receive FDA approval, we intend to apply for patent term extensions, if available, to extend the term of patents that cover the approved product candidates. We also intend to seek patent term extensions in any jurisdiction where they are available; however, there is no guarantee that the applicable authorities, including the FDA, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions. 29 The United States also offeff rs Patent Term Adjustment, or PTA, whereby a particular patent’s term is automatically extended beyond the 20-year term if the United States Patent and Trademark Officeff delays during the underlying patent application’s examination.

This collaboration was expanded in November 2017 through an Amended and Restated Option, License and Collaboration Agreement, which we refer to as the Restated Genentech Agreement. The collaboration is managed by a joint research committee and a joint project team, each of which is comprised of representatives from us and Genentech. Decisions of the joint research committee and joint project team are made by consensus, with each party having one vote. If the joint research committee is unable to agree, and the parties’ executives are not able to resolve the dispute, then Genentech has final decision- making authority, subject to specified limitations. Under the Restated Genentech Agreement, Genentech has the right to designate up to ten Targets forff further discovery and research utilizing our PROTAC platform technology.

For costs incurred in excess of 31 the budgeted amount, Genentech has the option of either having us continue the work on the Target and reimbursing us for our costs in doing so or terminating the work on such Target. The research program for each Target contemplates that the discovery and research work will occur in two stages: Stage 1, in which our objective will be to identify a PROTAC targeted protein degrader that demonstrates in vitro protein degradation of the Target; and Stage 2, in which our objective will be to demonstrate certain in vitro and in vivo research and development activity, but not to complete toxicology , at the conclusion of Stage 1, Genentech has studies or other necessary IND-enabling studies. For each Target the opportunity to continue the research program for such Target or terminate all activities on such Target. At the conclusion of each stage, we are obligated to provide certain deliverables to Genentech, including a data package at the end of Stage 2.

The royalty period for each Licensed PROTAC expires on a country-by-country basis upon either (1) the expiration of the last-to-expire valid patent claim covering such Licensed PROTAC or (2) ten years after the first commercial sale with respect to such Licensed PROTAC, depending on whether the sale of the Licensed PROTAC is covered by an applicable valid claim. The expiration of the last to expire patent right licensed to Genentech, if it issues as a patent and all appropriate maintenance fees are paid, is currently expected be in 2042. We could also obtain rights to additional patents, including through the issuance of pending patent applications, with later expiration dates, or new Licensed PROTACs could be added to the agreement that are subject to additional royalty terms with later expiration dates, which in either case could extend the term of the Restated Genentech Agreement. Genentech has the right to terminate the Restated Genentech Agreement for convenience in its entirety or with respect to a specific Target on 60 days’ prior notice. Either we or Genentech may terminate the agreement, in its entirety or with respect to a specific Target, if the other party is in material breach and such breach is not cured within the specified cure period.

Under the ARV-RR 471 Collaboration Agreement, we received an upfront, non-refundable payment of $650 million. In addition, we are eligible to receive up to an additional $1.4 billion in contingent payments based on specified regulatory and sales-based milestones for the Licensed Products.

Collaboration Agreement anywhere Competition The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on intellectual property and proprietary products. While we believe that our technology, expertise, scientific knowledge and intellectual property estate provide us with competitive advantages, we face potential competition from many differ ff specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research institutions that conduct research, seek patent protection, and establish collaborative arrangements forff we compete with other companies that are focused on protein degradation, but any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. Moreover, our industry is characterized by the existence of large numbers of patents and frequent allegations of patent infringement. research, development, manufacturing, and commercialization. Not only must ent sources, including major pharmaceutical, Our platform and product focus is the discovery and development of protein degradation therapies targeted protein degraders. Other companies researching chimeric small using our small molecule PROTACTT molecules for protein degradation include Accutar Biotechnology, Inc., C4 Therapeutics, Inc., Cullgen Inc., Foghorn Therapeutics, Inc., Kymera Therapeutics, Inc., Nurix Therapeutics, Inc. and Proteovant Therapeutics, Inc. Further, several large pharmaceutical companies have disclosed preclinical or clinical investments in this field, including AbbVie, Amgen, AstraZeneca plc, Boehringer Ingelheim, Bristol Myers Squibb Company, GlaxoSmithKline plc, Genentech, Novartis International AG and Sanofi SA. Since 2020, some of these biotechnology and pharmaceutical companies have announced the initation of clinical trials for targeted protein degraders. In addition to competition from other protein degradation therapies, any products that we develop may also face competition from other types of therapies, such as small molecule, antibody, or gene therapies. Our lead product candidates target oncologic indications. The most common methods of treating patients in oncologic indications are surgery, radiation and drug therapy, including chemotherapy, hormone therapy and targeted drug therapy. There are a variety of available drug therapies marketed for cancer, including prostate cancer and breast cancer. In many cases, these drugs are administered in combination to enhance efficacy . Some of the currently approved drug therapies are branded and subject to patent protection, ff 37 and others are available on a generic basis. Many of these approved drugs are well established therapies and are widely accepted by physicians, patients and third-party payors. In general, although there has been considerable progress over the past few decades in the treatment of cancer and the currently marketed and therapies provide benefits to many patients, these therapies all are limited to some extent in their efficacy frequency of adverse events, and none of them are successful in treating all patients. As a result, the level of morbidity and mortality from cancer remains high. ff In addition to currently marketed drugs, there are also several product candidates in late stage clinical development for the treatment of oncologic indications, including for mCRPC and metastatic ER positive / HER2 negative breast cancer. These products in development include, in the case of metastatic ER positive / HER2 negative breast cancer, selective estrogen receptor degraders and may provide efficacy , safety, convenience and other benefits that are not provided by currently marketed therapies. As a result, they may provide significant competition forff any of our product candidates for which we obtain market approval. ff If any of our product candidates are approved for the indications for which we expect to conduct clinical trials, they will compete with the foregoing therapies and the currently marketed drugs and potentially any drugs in development. It is also possible that we will face competition from other biologic or pharmaceutical approaches as well as from other types of therapies. Many of our current or potential competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are saferff more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position beforeff market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. There are generic products currently on the market for certain of the indications that we are pursuing, and additional products are expected to become available on a generic basis over the coming years. If our product candidates are approved, we expect that they will be priced at a significant premium over competitive generic products. ive, have fewer or less severe side effect we are able to enter the , more effect s, are ff ff The key competitive factors affect , safety, convenience, price, level of generic competition and availability of reimbursement. ing the success of all our programs, if approved, are likely to be their ff efficacy ff Commercialization Plans We have not yet established our own commercial organization or distribution capabilities because our product candidates are still in preclinical and clinical development. Other than our discovery collaboration all of our development programs. If any of our agreements, we have retained commercialization rights forff product candidates receive marketing approval, we will need to develop a plan to commercialize them in the United States and other key markets. We currently expect that we would build our own focused, specialized sales and marketing organization to support the commercialization in the United States of product candidates for which we receive marketing approval and that can be commercialized with such capabilities. We expect to utilize a variety of types of collaboration, co-promotion, distribution and other marketing arrangements with one or more third parties to commercialize our product candidates in markets outside the United States or for situations in which a larger sales and marketing organization is required. 38 As product candidates advance through our pipeline, our commercial plans may change. In particular, some of our research programs target potentially larger indications. Data, the size of the development programs, the size of the target market, the size of a commercial infrastructure and manufacturing needs may all influence our strategies in the United States, Europe and the rest of the world. Manufacturing and Supply We do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely on and expect to continue to rely on third-party contract manufacturing organizations, or CMOs, for both drug substance and finished drug product as well as for the synthesis of compounds in our pre-clinical research and development activities. We have engaged third-party manufacturers to supply the drug substances and building blocks for those substances for bavdegalutamide, ARV-RR 471 and ARV-RR 766. We have also engaged third- party manufacturers to develop and manufacture finished drug product for bavdegalutamide, ARV-RR 471 and ARV-RR 766 that we are using and plan to use in our ongoing and planned Phase 1/2 and planned pivotal clinical trials. We currently obtain our supplies from these manufacturers on a purchase order basis and do not have long-term supply arrangements in place. Should any of these manufacturers reason, we believe that there are a number of potential replacements, although we may incur some delay in identifying and qualifying become unavailable to us for any such replacements. ff ff All of our drug candidates are organic compounds of low molecular weight, generally called small molecules, but which are larger than traditional small molecule therapeutics. We have selected these compounds not only on the basis of their potential efficacy reasonable cost of goods. In particular, our lead product candidates are manufactured reproducible synthetic processes from readily available starting materials. The chemistry is amenable to scale up and does not require unusual equipment in the manufacturing process. We expect to continue to develop drug candidates that can be produced cost-effecti and safety, but also for their ease of synthesis and vely at contract manufacturing facilities. using reliable and ff ff ff Government Regulation and Product Approvals Government authorities in the United States, at the federal, state and local level, and in other countries f and jurisdictions, including the European Union, extensively regulate, among other things, the research, development, testing, manufactu re, pricing, quality control, approval, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, sales, reimbursement, post-approval monitoring and reporting, and import and export of biopharmaceutical products. The processes for obtaining marketing approvals in the United States and in foreign countries and jurisdictions, along with compliance with applicable statutes and regulations and other regulatory authorities, require the expenditure of substantial time and financial resources. rr Approval and Regulation ll of Drugs in the United States tt In the United States, drug products are regulated under the Federal Food, Drug, and Cosmetic Act, or FDCA, and applicable implementing regulations and guidance. A company, institution, or organization which takes responsibility for the initiation and management of a clinical development program for such products, and for their regulatory approval, is typically referred to as a sponsor. The failure of a sponsor to comply with the applicable regulatory requirements at any time during the product development process, including nonclinical testing, clinical testing, the approval process or post-approval process, may result in delays to the conduct of a study, regulatory review and approval and/or administrative or judicial sanctions. A sponsor seeking approval to market and distribute a new drug in the United States generally must the product candidate will be approved by the FDA: satisfactorily complete each of the following steps beforeff • • preclinical testing including laboratory tests, animal studies and formulation studies, which must be performed standards; in accordance with the FDA’sAA good laboratory practice, or GLP, regulations and ff completion of the manufactu of the drug substance and drug product that the sponsor intends to use in human clinical trials along with required analytical and stability testing; re, under current Good Manufacturing Practices, or cGMP, cP onditions, ff 39 • • • • • • • • • design of a clinical protocol and and submission to the FDA of an IND for human clinical testing, which must become effect human clinical trials may begin; ive beforeff ff approval by an independent institutional review board, or IRB, representing each clinical site before each clinical trial may be initiated; performance of adequate and well-controlled human clinical trials to establish the safety and efficacy practices, or GCP; each proposed indication, in accordance with good clinical of the product candidate forff ff preparation and submission to the FDA of a new drug application, or NDA, for a drug product which includes not only the results of the clinical trials, but also, detailed informat manufacture and quality controls for the product candidate and proposed labeling forff proposed indication(s); ion on the chemistry, one or more ff review of the product candidate by an FDA advisory committee, where appropriate or if applicable; satisfactory completion of an FDA inspection of the manufacturing facility or facilit those of third parties, at which the product candidate or components thereof are manufactured to assess compliance with cGMP requirements and to assure that the facilities, methods and controls are adequate to preserve the product’s identity, strength, quality and purity; ies, including ff satisfactory completion of any FDA audits of the clinical trial sites to assure compliance with GCP and the integrity of clinical data in support of the NDA; payment of user fees and securing FDA approval of the NDA to allow marketing of the new drug product; and compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation Strategies, or REMS, and the potential requirement to conduct any post-approval studies required by the FDA. ii linical Precrr Before a sponsor begins testing a product candidate with potential therapeutic value in humans, the Studies initial testing in humans and to establish rationale for therapeutic use.

Such authorization must be secured prior to interstate shipment and of an approved NDA. In support of a request for administration of any product candidate that is not the subject an IND, sponsors must submit a protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, the results of the preclinical tests, together with manufacturing informat among other things, must be submitted to the FDA as part of an IND. The FDA requires a 30-day waiting period after the filing of each IND beforeff review the IND to determine whether human research subjects will be exposed to unreasonable health risks. At any time during this 30-day period, or thereafter , the FDA may raise concerns or questions about the conduct of the trials as outlined in the IND and impose a clinical hold or partial clinical hold. In this case, the IND sponsor and the FDA must resolve any outstanding concerns beforeff ion, analytical data, any available clinical data or literature and plans for clinical trials, clinical trials may begin. This waiting period is designed to allow the FDA to clinical trials can begin or recommence. b ff ff Following commencement of a clinical trial under an IND, the FDA may also place a clinical hold or partial clinical hold on that trial. Clinical holds are imposed by the FDA whenever there is concern for patient safety and may be a result of new data, findings, or developments in clinical, nonclinical, and/or chemistry, 40 manufacturing, and controls, or CMC. A clinical hold is an order issued by the FDA to the sponsor to delay a proposed clinical investigation or to suspend an ongoing investigation. A partial clinical hold is a delay or suspension of only part of the clinical work requested under the IND. For example, a specific protocol or part of a protocol is not allowed to proceed, while other protocols may do so. No more than 30 days after imposition of a clinical hold or partial clinical hold, the FDA will provide the sponsor a written explanation of the basis for the hold. Following issuance of a clinical hold or partial clinical hold, an investigation may only resume after the FDA has notified the sponsor that the investigation may proceed. The FDA will base that determination on informat that the investigation can proceed. ion provided by the sponsor correcting the deficiencies previously cited or otherwise satisfying the FDA ff ff A sponsor may choose, but is not required, to conduct a foreign ff clinical study under an IND. When a foreign clinical study is conducted under an IND, all FDA IND requirements must be met unless waived. When a foreign clinical study is not conducted under an IND, the sponsor must ensure that the study complies with certain regulatory requirements of the FDA in order to use the study as support for an IND or application for marketing approval. Specifically, such studies must be conducted in accordance with GCP including review and approval by an independent ethics committee, or IEC, and informff requirements encompass both ethical and data integrity standards for clinical studies. The FDA’sAA regulations are intended to help ensure the protection of human subjects enrolled in non-IND foreign clinical studies, as well as the quality and integrity of the resulting data. They further help ensure that non-IND foreign studies are conducted in a manner comparable to that required for IND studies. ed consent from subjects. The GCP In addition to the foregoing IND requirements, an IRB representing each institution participating in the clinical trial must review and approve the plan for any clinical trial beforeff it commences at that institution, and the IRB must conduct continuing review and reapprove the study at least annually. The IRB must review and approve, among other things, the study protocol and informed ff subjects. An IRB must operate in compliance with FDA regulations. An IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to patients. consent information to be provided to study Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee, or DSMB. This group provides authorization as to whether or not a trial may move forward at designated check points based on certain available data from the study to which only the DSMB may access. Suspension or termination of development during any phase of clinical trials can occur if it is determined that the participants or patients are being exposed to an unacceptable health risk. Other reasons for suspension or termination may be made by us based on evolving business objectives and/or competitive climate. Expanxx ded Access to an Investigatio i nal Drugrr for Treatmen TT t UseUU Expanded access, sometimes called “compassionate use,” is the use of investigational new drug products outside of clinical trials to treat patients with serious or immediately life-threatening diseases or conditions when there are no comparable or satisfactory alternative treatment options. The rules and regulations related to expanded access are intended to improve access to investigational drugs for patients who may benefit from investigational therapies. FDA regulations allow access to investigational drugs under an IND by the company or the treating physician for treatment purposes on a case-by-case basis for: individual patients (single-patient IND applications for treatment in emergency settings and non-emergency settings); intermediate- size patient populations; and larger populations for use of the drug under a treatment protocol or Treatment IND Application. When considering an IND application for expanded access to an investigational product with the purpose of treating a patient or a group of patients, the sponsor and treating physicians or investigators will determine suitability when all of the following criteria apply: patient(s) have a serious or immediately life- threatening disease or condition, and there is no comparable or satisfactory alternative therapy to diagnose, monitor, or treat the disease or condition; the potential patient benefit justifies the potential risks of the treatment and the potential risks are not unreasonable in the context or condition to be treated; and the expanded use of the investigational drug for the requested treatment will not interfere initiation, conduct, or completion of clinical 41 investigations that could support marketing approval of the product or otherwise compromise the potential development of the product. There is no obligation for a sponsor to make its drug products available for expanded access. However, if a sponsor has a policy regarding how it responds to expanded access requests, it must make that policy available. This provision requires drug and biologic companies to make publicly available their policies for expanded access for individual patient access to products intended for serious diseases. Sponsors are required to make such policies publicly available upon the earlier of initiation of a Phase 2 or Phase 3 study; or 15 days after the drug or biologic receives designation as a breakthrough therapy, fast track product, or regenerative medicine advanced therapy. We received fast track designation forff bavdegalutamide for mCRPC in May 2019. In addition, on May 30, 2018, the Right to Try Act, was signed into law. The law, among other things, provides a federal framework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without needing FDA approval under the FDA expanded access program. There is no obligation for a drug manufacturer to make its drug products available to eligible patients under the Right to Try Act. Human Clini ii cal Trials rr in Suppu ort orr f an NDA Clinical trials involve the administration of the investigational product candidate to human subjects under the supervision of a qualified investigator in accordance with GCP requirements which include, among other things, the requirement that all research subjects provide their informed their participation in any clinical trial. Clinical trials are conducted under written clinical trial protocols detailing, among other things, the objectives of the study, inclusion and exclusion criteria, the parameters to be used in monitoring safety and the effect iveness criteria to be evaluated. consent in writing beforeff ff ff Human clinical trials are typically conducted in three sequential phases, but the phases may overlap or be combined. Additional studies may also be required after approval.

A well-controlled, statistically robust Phase 3 clinical trial may be designed to deliver the data that regulatory authorities will use to decide whether or not to approve, and, if approved, how to appropriately label a drug: such Phase 3 studies are referred to as “pivotal.” and further test for safety in an expanded and diverse patient population at multiple, geographically A clinical trial may combine the elements of more than one phase and the FDA often requires more than one Phase 3 trial to support marketing approval of a product candidate. A company’s designation of a clinical trial as being of a particular phase is not necessarily indicative that the study will be sufficient requirements of that phase because this determination cannot be made until the protocol and data have been submitted to and reviewed by the FDA. Moreover, as noted above, a pivotal trial is a clinical trial that is believed to satisfy FDA requirements for the evaluation of a product candidate’s safetyf used, alone or with other pivotal or non-pivotal trials, to support regulatory approval. Generally, pivotal trials are such that it can be to satisfy the FDA ff and efficacy ff 42 Phase 3 trials, but they may be Phase 2 trials if the design provides a well-controlled and reliable assessment of clinical benefit, particularly in an area of unmet medical need. In some cases, the FDA may approve an NDA for a product candidate but require the sponsor to conduct additional clinical trials to further assess the product candidate’s safety and effecti approval. Such post-approval trials are typically referred to as Phase 4 clinical trials. These studies are used to gain additional experience from the treatment of a larger number of patients in the intended treatment group and to further document a clinical benefit in the case of drugs approved under accelerated approval regulations. Failure to exhibit due diligence with regard to conducting Phase 4 clinical trials could result in withdrawal of approval for products. veness after ff In August 2018, the FDA released a draft guidance entitled “Expansion Cohorts: Use in First-In-Human Clinical Trials to Expedite Development of Oncology Drugs and Biologics,” which outlines how sponsors can utilize an adaptive trial design in the early stages of oncology product development (i.e., the first-in-human clinical trial) to compress the traditional three phases of trials into one continuous trial called an expansion cohort trial. Information to support the design of individual expansion cohorts are included in IND applications and assessed by FDA. Expansion cohort trials can potentially bring efficiency reduce developmental costs and time. to product development and ff Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. In addition, IND safety reports must be submitted to the FDA for any of the following: serious and unexpected suspected adverse reactions; findings from other studies or animal or in vitro testing that suggest a significant risk to humans exposed to the product; and any clinically important increase in the case of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. The FDA will typically inspect one or more clinical sites to assure compliance with GCPs and the integrity of the clinical data submitted.

The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, must develop methods for testing the identity, strength, quality, purity, and potency of the final drug. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life. Specifically, the FDA’sAA regulations require that pharmaceutical products be manufactured in specific approved facilities and in accordance with cGMPs. The cGMP regulations include requirements relating to organization of personnel, buildings and facilities, equipment, control of components and product containers and closures, production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports and returned or salvaged products. Manufacturers and other entities involved in the manufacture and distribution of approved pharmaceuticals are required to register their establishments with the FDA and some state agencies, and they are subject to periodic unannounced inspections by the FDA for compliance with cGMPs and other requirements. Inspections must follow a “risk-based schedule” that may result in certain establishments being inspected more frequently. Manufacturers may also have to provide, on request, electronic or physical records regarding their establishments. Delaying, denying, limiting, or refusing inspection by the FDA may lead to a product being deemed to be adulterated.

For applications seeking approval of products that are not NMEs, the ten-month and six-month review periods run from the date that the FDA receives the application. The review process and the Prescription Drug User Fee Act, or PDUFA,FF goal date may be extended by the FDA for three additional months to consider new informat ion or clarification provided by the sponsor to address an outstanding deficiency identified by the FDA following the original submission. ff In connection with its review of an application, the FDA typically will inspect the facility or facilit the product is or will be manufactured. These pre-approval inspections may cover all facilities associated with an NDA submission, including component manufacturing, finished product manufacturing and control testing laboratories. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Under the FDA Reauthorization Act of 2017, the FDA must implement a protocol to expedite review of responses to inspection reports pertaining to certain applications, including applications for products in shortage or those for which approval is dependent on remediation of conditions identified in the inspection report. ies where ff ff In addition, as a condition of approval, the FDA may require a sponsor to develop a REMS. REMS use risk minimization strategies beyond the professional labeling to ensure that the benefits of the product outweigh the potential risks. To determine whether a REMS is needed, the FDA will consider the size of the population likely to use the product, seriousness of the disease, expected benefit of the product, expected duration of treatment, seriousness of known or potential adverse events and whether the product is a new molecular entity. The FDA may referff an application for a novel product to an advisory committee or explain why such referral was not made. Typically, an advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. The FDA is authorized to expedite the review of applications in several ways. Under the Fast Track program, the sponsor of a product candidate may request the FDA to designate the product for a specific indication as a Fast Track product concurrent with or after the filing of the IND. Candidate products are eligible for Fast Track designation if they are intended to treat a serious or life-threat the potential to address unmet medical needs for the condition.

In addition, the FDA currently requires as a condition for accelerated approval pre- approval of promotional materials. adequate and well controlled post-marketing advanced therapy. With passage of the 21st Century Cures Act, or the Cures Act, in Regenerativett December 2016, Congress authorized the FDA to accelerate review and approval of products designated as regenerative advanced therapies.

The CRL may require additional clinical or other data, additional pivotal Phase 3 clinical trial(s) and/or other significant and time- consuming requirements related to clinical trials, preclinical studies or manufactu ring. If a CRL is issued, the sponsor will have one year to respond to the deficiencies identified by the FDA, at which time the FDA can deem the application withdrawn or, in its discretion, grant the sponsor an additional six month extension to respond. The FDA has committed to reviewing resubmissions in response to an issued CRL in either two or six months depending on the type of information included. Even with the submission of this additional informat however, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. The FDA has taken the position that a CRL is not final agency action making the determination subject to judicial review. ion, f ff An approval letter, on the other hand, authorizes commercial marketing of the product with specific prescribing information for specific indications. That is, the approval will be limited to the conditions of use (e.g., patient population, indication) described in the FDA-approved labeling. Further, depending on the specific risk(s) to be addressed, the FDA may require that contraindications, warnings or precautions be included in the product labeling, require that post-approval trials, including Phase 4 clinical trials, be conducted to further assess a product’s safety after approval, require testing and surveillance programs to monitor the product after commercialization or impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS which can materially affect product.

This could subject a company to a range of penalties that could have a significant commercial impact, including civil and criminal fines and agreements that materially restrict the manner in which a company promotes or distributes drug products. The federal government has levied large civil and criminal fines against companies for alleged improper promotion, and has also requested that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed. ff ff Section 505(b)(2) NDAs ff NDAs forff most new drug products are based on two full clinical studies which must contain substantial of the proposed new product for the proposed use. These applications are evidence of the safety and efficacy submitted under Section 505(b)(1) of the FDCA. The FDA is, however, authorized to approve an alternative type of NDA under Section 505(b)(2) of the FDCA. This type of application allows the sponsor to rely, in part, on the for a similar product, or published literature. Specifically, Section FDA’sAA previous findings of safety and efficacy 505(b)(2) applies to NDAs forff a drug forff which the investigations made to show whether or not the drug is safe for use and effect ive in use and relied upon by the sponsor for approval of the application “were not conducted by or for the sponsor and for which the sponsor has not obtained a right of reference or use from the person by or for whom the investigations were conducted.” ff ff Section 505(b)(2) thus authorizes the FDA to approve an NDA based on safety and effecti that were not developed by the sponsor. NDAs filed under Section 505(b)(2) may provide an alternate and potentially more expeditious pathway to FDA approval for new or improved formulations or new uses of previously approved products. If the 505(b)(2) sponsor can establish that reliance on the FDA’sAA previous approval is scientifically appropriate, the sponsor may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies to performff measurements to support the change from the approved product. The FDA may then approve the new drug candidate forff for any new indication sought by the Section 505(b)(2) sponsor. all or some of the label indications for which the referenced product has been approved, as well as additional studies or veness data f ff Abbreviated New Drugrr Applpp icall tions for Generic Drugrr s In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress established an abbreviated regulatory scheme authorizing the FDA to approve generic drugs that are shown to contain the same active ingredients as, and to be bioequivalent to, drugs previously approved by the FDA pursuant to NDAs. To obtain approval of a generic drug, a sponsor must submit an abbreviated new drug application, or 48 ff ion pertaining to the active pharmaceutical ingredient, bioequivalence, drug product formulation, ANDA, to the agency. An ANDA is a comprehensive submission that contains, among other things, data and informat specifications and stability of the generic drug, as well as analytical methods, manufactu ring process validation data and quality control procedures. ANDAs are “abbreviated” because they generally do not include preclinical and clinical data to demonstrate safety and effeff ctiveness. Instead, in support of such applications, a generic manufacturer may rely on the preclinical and clinical testing previously conducted for a drug product previously approved under an NDA, known as the reference-listed drug, or RLD. ff Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, the strength of the drug and the conditions of use of the drug. At the same time, the FDA must also determine that the generic drug is “bioequivalent” to the innovator drug. Under the statute, a generic drug is bioequivalent to a RLD if “the rate and extent of absorption of the drug do not show a significant difference from the rate and extent of absorption of the listed drug.” Upon approval of an ANDA, the FDA indicates whether the generic product is “therapeutically equivalent” to the RLD in its publication “Approved Drug Products with Therapeutic Equivalence Evaluations,” also referred to as the “Orange Book.” Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully substitutable for the RLD. In addition, by operation of certain state laws and numerous health insurance programs, the FDA’sAA designation of therapeutic equivalence oftenff substitution of the generic drug without the knowledge or consent of either the prescribing physician or patient. results in Under the Hatch-Waxman Amendments, the FDA may not approve an ANDA until any applicable period the RLD has expired. The FDCA provides a period of five years of non-patent data a new drug containing a new chemical entity. For the purposes of this provision, a new chemical of non-patent exclusivity forff exclusivity forff entity, or NCE, is a drug that contains no active moiety that has previously been approved by the FDA in any other NDA. This interpretation was confirmed with enactment of the Ensuring Innovation Act in April 2021. An active moiety is the molecule or ion responsible forff substance. In cases where such NCE exclusivity has been granted, an ANDA may not be filed with the FDA until the expiration of five years unless the submission is accompanied by a Paragraph IV certification, in which case the sponsor may submit its application four years following the original product approval. the physiological or pharmacological action of the drug The FDCA also provides for a period of three years of exclusivity if the NDA includes reports of one or more new clinical investigations, other than bioavailability or bioequivalence studies, that were conducted by or for the applicant and are essential to the approval of the application. This three-year exclusivity period often protects changes to a previously approved drug product, such as a new dosage form, route of administration, combination or indication. Three-year exclusivity would be available forff previously approved active moiety, provided the statutory requirement for a new clinical investigation is satisfied. Unlike five-year NCE exclusivity, an award of three-year exclusivity does not block the FDA from accepting ANDAs seeking approval for generic versions of the drug as of the date of approval of the original drug product. The FDA typically makes decisions about awards of data exclusivity shortly beforeff a drug product that contains a a product is approved. The FDA must establish a priority review track for certain generic drugs, requiring the FDA to review a drug application within eight (8) months for a drug that has three (3) or fewer approved drugs listed in the Orange Book and is no longer protected by any patent or regulatory exclusivities, or is on the FDA’sAA drug shortage list. The FDA is also authorized to expedite review of “competitor generic therapies” or drugs with inadequate generic competition, including holding meetings with or providing advice to the drug sponsor prior to submission of the application. Hatch-Waxman Patent Certificati ii on and thett 30-Month Stay Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims that cover the sponsor’s product or an approved method of using the product. Each of the patents listed by the NDA sponsor is published in the Orange Book. The FDA’sAA regulations governing patient listings were largely codified into law with enactment of the Orange Book Modernization Act in January 2021. When an ANDA sponsor files its application with the FDA, the sponsor is required to certify to the FDA concerning any patents listed for the reference product in the Orange Book, except for patents covering methods of use for which the ANDA sponsor is not seeking approval. To the extent that the Section 505(b)(2) sponsor is relying on studies conducted for an already approved product, the sponsor is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA sponsor would. 49 Specifically, the sponsor must certify with respect to each patent that: • • • • the required patent information has not been filed; the listed patent has expired; the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or the listed patent is invalid, unenforceable ff or will not be infringed by the new product. A certification that the new product will not infringe the already approved product’s listed patents or that such patents are invalid or unenforceable is called a Paragraph IV certification. If the sponsor does not challenge the listed patents or indicates that it is not seeking approval of a patented method of use, the application will not be approved until all the listed patents claiming the referenced product have expired (other than method of use patents involving indications for which the sponsor is not seeking approval). ff If the ANDA sponsor has provided a Paragraph IV certification to the FDA, the sponsor must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days after the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months after the receipt of the Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to the ANDA sponsor. ff To the extent that the Section 505(b)(2) sponsor is relying on studies conducted for an already approved product, the sponsor is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA sponsor would. As a result, approval of a Section 505(b)(2) NDA can be stalled until all the listed patents claiming the referenced product have expired, until any non-patent exclusivity, such as exclusivity forff obtaining approval of a new chemical entity, listed in the Orange the referenced product has expired, and, in the case of a Paragraph IV certification and subsequent Book forff patent infringement suit, until the earlier of 30 months, settlement of the lawsuit or a decision in the infringement case that is favorable to the Section 505(b)(2) sponsor. ii Pediatri c ExclEE usivity Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional six months of regulatory exclusivity to the term of any patent or existing regulatory exclusivity, including orphan exclusivity. This six-month exclusivity may be granted if an NDA sponsor submits pediatric data that fairly respond to a written request from the FDA for such data. The data do not need to show the product to be effect ive in the pediatric population studied; rather, if the clinical trial is deemed to fairly respond to the FDA’s request, the additional protection is granted. If reports of requested pediatric studies are submitted to and accepted by the FDA within the statutory time limits, whatever statutory or regulatory periods of exclusivity or patent protection cover the product are extended by six months. This is not a patent term extension, but it effectively extends the regulatory period during which the FDA cannot approve another application. ff Orphan Drug Designi ation and Exclusivity Under the Orphan Drug Act, the FDA may designate a drug product as an “orphan drug” if it is intended to treat a rare disease or condition, generally meaning that it affects fewer than 200,000 individuals in the United States, or more in cases in which there is no reasonable expectation that the cost of developing and making a product available in the United States for treatment of the disease or condition will be recovered from sales of the product. A company must seek orphan drug designation beforeff product. If the request is granted, the FDA will disclose the identity of the therapeutic agent and its potential use. Orphan drug designation does not shorten the PDUFA gFF process, although it does convey certain advantages such as tax benefits and exemption from the PDUFAFF application fee. oal dates for the regulatory review and approval submitting an NDA for the candidate 50 If a product with orphan designation receives the first FDA approval forff the disease or condition for which it has such designation or for a select indication or use within the rare disease or condition for which it was designated, the product generally will receive orphan drug exclusivity. Orphan drug exclusivity means that the FDA may not approve another sponsor’s marketing application for the same drug for the same condition for seven years, except in certain limited circumstances. Orphan exclusivity does not block the approval of a different different indication broader than what was designated in its orphan drug application, it may not be entitled to exclusivity. product for the same rare disease or condition, nor does it block the approval of the same product for conditions. If a drug designated as an orphan drug ultimately receives marketing approval for an ff ff The period of market exclusivity begins on the date that the marketing application is approved by the FDA and applies only to the disease or condition for which the product has been designated. Orphan drug exclusivity will not bar approval of another product under certain circumstances, including if the company with orphan drug exclusivity is not able to meet market demand or the subsequent product is shown to be clinically superior to the approved product on the basis of greater efficacy or safety, or providing a major contribution to patient care. This is the case despite an earlier court opinion holding that the Orphan Drug Act unambiguously required the FDA to recognize orphan drug exclusivity regardless of a showing of clinical superiority. Under Omnibus legislation signed by President Trump on December 27, 2020, the requirement forff clinical superiority applies to drug products that received orphan drug designation beforeff amendments to the FDCA in 2017 but have not yet been approved by FDA. a product to show enactment of ff In September 2021, the Court of Appeals for the 11th Circuit held that, forff the purpose of determining the scope of market exclusivity, the term “same disease or condition” in the statute means the designated “rare disease or condition” and could not be interpreted by the FDA to mean the “indication or use.” Thus, the court concluded, orphan drug exclusivity applies to the entire designated disease or condition rather than the “indication or use.” It is unclear how this court decision will be implemented by the FDA. Patent TermTT Restoration and Extension A patent claiming a new drug product, its method of use or its method of manufacture may be eligible for a limited patent term extension under the Hatch-Waxman Act, which permits a patent restoration of up to five years for patent term lost during product development and the FDA regulatory review. The restoration period granted on a patent covering a product is typically one-half the time between the effecti ve date of the IND for the clinical investigation is begun and the submission date of an application, plus the time between the submission date of an application and the ultimate approval date. Patent term restoration cannot be used to extend the remaining term of a patent past a total of 14 years from the product’s approval date. Only one patent applicable to an approved product is eligible forff submitted prior to the expiration of the patent in question.

Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other government authorities. Thus, even if a product candidate is approved, sales of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United States such as Medicare and Medicaid, commercial health insurers and managed care organizations, provide coverage and establish adequate reimbursement levels for the product. The process for determining whether a payor will provide coverage for a product may be separate from the process for setting the price or reimbursement rate that the payor will pay for the product once coverage is approved. Third-party payors are increasingly challenging the prices charged, examining the medical necessity and reviewing the cost-effectiveness of medical products and services and imposing controls to manage costs. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary might not include all of the approved products forff a particular indication. ff , which In order to secure coverage and reimbursement forff any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effect comparable marketing approvals.

Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit a company’s revenue generated from the sale of any approved products. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products forff which a company or its collaborators receive marketing approval, less favorable coverage policies and reimbursement rates may be implemented in the future. Governments have shown significant s in this effort. ff There have been a number of federal and state proposals during the last few years regarding the pricing of pharmaceutical and biopharmaceutical products, limiting coverage and reimbursement forff biologics and other medical products, government control and other changes to the health care system in the United States. drugs and In March 2010, President Obama signed into law the Patient Protection and Affordable ff Care Act, as ff amended by the Health Care and Education Afford ability Reconciliation Act, or collectively the ACA. In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes included aggregate reductions of Medicare payments to providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect or the CARES Act. These Medicare sequester reductions have been suspended through the end of March 2022. From April 2022 through June 2022 a 1% sequester cut will be in effect thereafter several providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding and otherwise affect may obtain regulatory approval or the frequency with which any such product candidate is prescribed or used. .

For example, with enactment of the Tax Cuts and Jobs Act of 2017, which was signed by President Trump on December 22, 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of ive in 2019. On December 14, 2018, a U.S. District Court judge in the Northern health insurance, became effect District of Texas ruled that the individual mandate portion of the ACA is an essential and inseverable feature of the ACA, and therefore because the mandate was repealed as part of the Tax Act, the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court heard this case on November 10, 2020 and, on June 17, 2021, dismissed this action after finding that the plaintiffsff do not have standing to challenge the constitutionality of the ACA. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results. ff The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including directing federal agencies with authorities and responsibilities under the ACA to waive, deferff , grant exemptions from, or delay the implementation of any provision of the ACA that would impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. On January 28, 2021, however, President Biden rescinded those orders and issued a new executive order that directs federal agencies to reconsider rules and other policies that limit access to healthcare, and consider actions that will protect and strengthen that access. Under this order, federal agencies are directed to re-examine: policies that undermine protections for people with pre-existing conditions, including complications related to COVID‑19; demonstrations and waivers under Medicaid and the ACA that may reduce coverage or undermine the programs, including work requirements; policies that undermine the 53 Health Insurance Marketplace or other markets for health insurance; policies that make it more difficult in Medicaid and under the ACA; and policies that reduce afford including forff ability of coverage or financial assistance, dependents. ff ff to enroll The prices of prescription pharmaceuticals have also been the subject b of considerable discussion in the United States. There have been several recent U.S. congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency to pharmaceutical pricing, review the relationship between pricing and manufacturer patient programs, and reduce the costs of pharmaceuticals under Medicare and Medicaid. In 2020, President Trump issued several executive orders intended to lower the costs of prescription products and certain provisions in these orders have been incorporated into regulations. These regulations include an interim final rule implementing a most favored nation model for prices that would tie Medicare Part B payments forff pharmaceuticals to the lowest price paid in other economically advanced countries, effect ive January 1, 2021. That rule, however, has been subject to a nationwide preliminary injunction and, on December 29, 2021, CMS issued a final rule to rescind it. With issuance of this rule, CMS stated that it will explore all options to incorporate value into payments forff Medicare Part B pharmaceuticals and improve beneficiaries' access to evidence-based care. certain physician-administered ff In addition, in October 2020, HHS and the FDA published a final rule allowing states and other entities to develop a Section 804 Importation Program, or SIP, to import certain prescription drugs from Canada into the United States. The final rule is currently the subject of ongoing litigation, but at least six states (Vermont , Colorado, Florida, Maine, New Mexico, and New Hampshire) have passed laws allowing forff drugs from Canada with the intent of developing SIPs for review and approval by the FDA. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed by the Biden administration until January 1, 2023. as well as a new safe harbor the importation of VV f On July 9, 2021, President Biden signed Executive Order 14063, which focuses on, among other things, the price of pharmaceuticals. The Order directs the Department of Health and Human Services, or HHS, to create a plan within 45 days to combat “excessive pricing of prescription pharmaceuticals and enhance domestic pharmaceutical supply chains, to reduce the prices paid by the federal government for such pharmaceuticals, and to address the recurrent problem of price gouging.” On September 9, 2021, HHS released its plan to reduce pharmaceutical prices. The key features of that plan are to: (a) make pharmaceutical prices more afford by supporting pharmaceutical price negotiations with manufacturers; (b) improve and promote competition throughout the prescription pharmaceutical industry by supporting market changes that strengthen supply chains, promote biosimilars and generic drugs, and increase transparency; and (c) foster scientific innovation to promote better healthcare and improve health by supporting public and private research and making sure that market incentives promote discovery of valuable and accessible new treatments. able and equitable for all consumers and throughout the health care system ff At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. A number of states, for example, require drug manufacturers and other entities in the drug supply chain, including health carriers, pharmacy benefit managers, wholesale distributors, to disclose informat pharmaceuticals. bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription pharmaceutical and other healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. In addition, regional healthcare organizations and individual hospitals are increasingly using ion about pricing of ff 54 Review and Appropp val of Medicidd nal ii Prodrr ucts in the European UniUU on In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficff acy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, a sponsor will need to obtain the necessary approvals by the comparable non-U.S. regulatory authorities beforeff marketing of the product in those countries or jurisdictions. The approval process ultimately varies between countries and jurisdictions and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure jurisdiction may negatively impact the regulatory process in others. Specifically, however, the process governing approval of medicinal products in the European Union, or EU, generally follows the same lines as in the United States. It entails satisfactory completion of preclinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy of the product for each proposed indication. It also requires the submission to the relevant competent authorities of a marketing authorization application, or MAA,AA and granting of a marketing authorization by these authorities beforeff or delay in obtaining regulatory approval in one country or the product can be marketed and sold in the EU. it can commence clinical trials or from and be longer ff ff ff Clinical Trial TT Approval On January 31, 2022, the new Clinical Trials Regulation (EU) No 536/2014 became effecti ff ve in the and streamlining the authorization, conduct and transparency of clinical trials in the European Union.

The new regulation did not change the preexisting requirement that a sponsor must obtain prior approval from the competent national authority of the EU Member State in which the clinical trial is to be conducted. If the clinical trial is conducted in differe these EU Member States must provide their approval for the conduct of the clinical trial.

PRIME Designation in the EU In March 2016, the European Medicines Agency, or EMA, launched an initiative to facilitate development of product candidates in indications, oftenff rare, forff which few or no therapies currently exist. The PRIority MEdicines, or PRIME, scheme is intended to encourage drug development in areas of unmet medical need and provides accelerated assessment of products representing substantial innovation reviewed under the centralized procedure. Products from small- and medium-sized enterprises, or SMEs, may qualify f entry into the PRIME scheme than larger companies. Many benefits accrue to sponsors of product candidates with PRIME designation, including but not limited to, early and proactive regulatory dialogue with the EMA, frequent discussions on clinical trial designs and other development program elements, and accelerated marketing authorization application assessment once a dossier has been submitted. Importantly, a dedicated Agency contact and rapporteur from the Committee for Human Medicinal Products, or CHMP, oP r Committee for Advanced Therapies, or CAT,AA are appointed early in PRIME scheme facilitating increased understanding of the product at EMA’s Committee level.

The respective requirements for all marketing authorization procedures are laid down in Regulation (EC) No 1901/2006, the so-called Paediatric Regulation. This requirement also applies when a company wants to add a new indication, pharmaceutical form or route of administration for a medicine that is already authorized. The Paediatric Committee of the EMA, or PDCO, may grant deferrals for some medicines, allowing a company to delay development of the medicine for children until there is enough information to demonstrate its effectiveness and safety in adults. The PDCO may also grant waivers when development of a medicine for children is not needed or is not appropriate, such as for diseases that only affect amended, the EMA determines that companies actually comply with the agreed studies and measures listed in each relevant PIP. the elderly population. Before an MAA can be filed, or an existing marketing authorization can be ff Marketingii Authorization To obtain a marketing authorization forff a product under EU regulatory systems, a sponsor must submit an MAA either under a centralized procedure administered by the EMA, or one of the procedures administered by competent authorities in the EU Member States (decentralized procedure or mutual recognition procedure). A marketing authorization may be granted only to a sponsor established in the EU. Regulation (EC) No 1901/2006 provides that prior to obtaining a marketing authorization in the EU, sponsors have to demonstrate compliance with all measures included in an EMA-approved PIP covering all subsets of the pediatric population, unless the EMA has granted (1) a product-specific waiver, (2) a class waiver or (3) a deferral for one or more of the measures included in the PIP. The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid across the European Economic Area (i.e. the EU as well as Iceland, Liechtenstein and Norway). Pursuant to Regulation (EC) No 726/2004, the centralized procedure is compulsory for specific products, including forff medicines produced by certain biotechnological processes, products designated as orphan medicinal products, advanced therapy medicinal products and products with a new active substance indicated for the treatment of certain diseases, including products for the treatment of cancer. For products with a new active substance indicated for the treatment of other diseases and products that are highly innovative or for which a centralized process is in the interest of patients, the centralized procedure may be optional. The centralized procedure may at the request of the applicant also be used in certain other cases. Under the centralized procedure, the CHMP is responsible for conducting the initial assessment of a ff ion or product and for several post-authorization and maintenance activities, such as the assessment of modifications or extensions to an existing marketing authorization. Under the centralized procedure in the EU, the maximum timeframe for the evaluation of an MAA is 210 days, excluding clock stops, when additional informat written or oral explanation is to be provided by the applicant in response to questions of the CHMP. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation. If the CHMP accepts such request, the time limit of 210 days will be reduced to 150 days but it is possible that the CHMP can revert to the standard time limit for the centralized procedure if it considers that it is no longer appropriate to conduct an accelerated assessment. At the end of this period, the CHMP provides a scientific opinion on whether or not a marketing authorization should be granted in relation to a medicinal product. Within 15 calendar days of receipt of a final opinion from the CHMP, tP he European Commission must prepare a draftff decision concerning an application for marketing authorization. This draft dff ecision must take the opinion and any relevant provisions of EU law into account. Before arriving at a final decision on an application for centralized authorization of a medicinal product the European Commission must consult the Standing Committee on Medicinal Products forff Human Use. The Standing Committee is composed of representatives of the EU Member States and chaired by a non-voting European Commission representative. The European Parliament also has a related “droit de regard.” The European Parliament’s role is to ensure that the European Commission has not exceeded its powers in deciding to grant or refuse to grant a marketing authorization. The European Commission may grant a so-called “marketing authorization under exceptional circumstances.” Such authorization is intended for products forff which the sponsor can demonstrate that it is 56 unable to provide comprehensive data on the efficff acy and safety under normal conditions of use, because the indications for which the product in question is intended are encountered so rarely that the sponsor cannot reasonably be expected to provide comprehensive evidence, or in the present state of scientific knowledge, comprehensive information cannot be provided, or it would be contrary to generally accepted principles of medical ethics to collect such information. Consequently, marketing authorization under exceptional circumstances may be granted subject to certain specific obligations, which may include the following: • • • the sponsor must complete an identified program of studies within a time period specified by the competent authority, the results of which form the basis of a reassessment of the benefit/risk profile; the medicinal product in question may be supplied on medical prescription only and may in certain cases be administered only under strict medical supervision, possibly in a hospital and in the case of a radiopharmaceutical, by an authorized person; and the package leaflet and any medical informat to the fact that the particulars available concerning the medicinal product in question are as yet inadequate in certain specified respects. ion must draw the attention of the medical practitioner ff A marketing authorization under exceptional circumstances is subject to annual review to reassess the risk-benefit balance in an annual reassessment procedure. Continuation of the authorization is linked to the annual reassessment and a negative assessment could potentially result in the marketing authorization being suspended or revoked. The renewal of a marketing authorization of a medicinal product under exceptional circumstances, however, fol lows the same rules as a “normal” marketing authorization. Thus, a marketing authorization under exceptional circumstances is granted for an initial five years, afteff will become valid indefinitely, unless the EMA decides that safety grounds merit one additional five-year renewal. r which the authorization ff The European Commission may also grant a so-called “conditional marketing authorization” prior to obtaining the comprehensive clinical data required for an application for a full marketing authorization. Such conditional marketing authorizations may be granted for product candidates (including medicines designated as orphan medicinal products), if (i) the risk-benefit balance of the product candidate is positive, (ii) it is likely that the sponsor will be in a position to provide the required comprehensive clinical trial data, (iii) the product fulfills an unmet medical need and (iv) the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still required. A conditional marketing authorization may contain specific obligations to be fulfilled by the marketing authorization holder, including obligations with respect to the completion of ongoing or new studies, and with respect to the collection of pharmacovigilance data. Conditional marketing authorizations are valid for one year, and may be renewed annually, if the risk-benefit balance remains positive, and after an assessment of the need for additional or modified conditions and/or specific obligations. The timelines for the centralized procedure described above also apply with respect to the review by the CHMP of applications for a conditional marketing authorization. The EU medicines rules expressly permit the EU Member States to adopt national legislation prohibiting or restricting the sale, supply or use of any medicinal product containing, consisting of or derived from a specific type of human or animal cell, such as embryonic stem cells. While the products we have in development do not make use of embryonic stem cells, it is possible that the national laws in certain EU Member States may prohibit or restrict us from commercializing our products, even if they have been granted an EU marketing authorization. Unlike the centralized authorization procedure, the decentralized marketing authorization procedure requires a separate application to, and leads to separate approval by, the competent authorities of each EU Member State in which the product is to be marketed. This application is identical to the application that would be submitted to the EMA for authorization through the centralized procedure. The reference EU Member State prepares a draft assessment and drafts of the related materials within 120 days after receipt of a valid application. The resulting assessment report is submitted to the concerned EU Member States who, within 90 days of receipt, must decide whether to approve the assessment report and related materials. If a concerned EU Member State cannot approve the assessment report and related materials due to concerns relating to a potential serious risk to public health, disputed elements may be referred decision is binding on all EU Member States. to the European Commission, whose ff 57 The mutual recognition procedure similarly is based on the acceptance by the competent authorities of the EU Member States of the marketing authorization of a medicinal product by the competent authorities of other EU Member States. The holder of a national marketing authorization may submit an application to the competent authority of an EU Member State requesting that this authority recognize the marketing authorization delivered by the competent authority of another EU Member State. ll Regulatory Data Protection in the EU In the EU, innovative medicinal products approved on the basis of a complete independent data ff orff package qualify f eight years of data exclusivity upon marketing authorization and an additional two years of market exclusivity pursuant to Directive 2001/83/EC. Regulation (EC) No 726/2004 repeats this entitlement for medicinal products authorized in accordance the centralized authorization procedure. Data exclusivity prevents the innovator’s data to ff sponsors for authorization of generics of these innovative products from referencing assess a generic (abridged) application forff a period of eight years. During an additional two-year period of market exclusivity, a generic marketing authorization application can be submitted and authorized, and the innovator’s data may be referenced, but no generic medicinal product can be placed on the EU market until the expiration of the market exclusivity. The overall ten-year period will be extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity so that the innovator gains the prescribed period of data exclusivity, another company nevertheless could also market another version of the product if such company obtained marketing authorization based on an MAA with a complete independent data package of pharmaceutical tests, preclinical tests and clinical trials. Periorr ds of Authorization and Renewalsll A marketing authorization has an initial validity forff five years in principle. The marketing authorization may be renewed after five years on the basis of a re-evaluation of the risk-benefit balance by the EMA or by the competent authority of the EU Member State. To tTT his end, the marketing authorization holder must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the marketing authorization was granted, at least six months beforeff marketing authorization ceases to be valid. The European Commission or the competent authorities of the EU Member States may decide, on justified grounds relating to pharmacovigilance, to proceed with one further five- year period of marketing authorization. Once subsequently definitively renewed, the marketing authorization shall be valid for an unlimited period. Any authorization which is not followed by the actual placing of the medicinal product on the EU market (in case of centralized procedure) or on the market of the authorizing EU Member State within three years after authorization ceases to be valid (the so-called sunset clause). the ii Pediatri c ExclEE usivity If a sponsor obtains a marketing authorization in all EU Member States, or a marketing authorization granted in the centralized procedure by the European Commission, and the study results forff population are included in the product information, even when negative, the medicine is then eligible forff additional six-month period of qualifying patent protection through extension of the term of the Supplementary Protection Certificate, or SPC. the pediatric an Orphan Drugrr Designi ation and Exclusivity Regulation (EC) No. 141/2000, as implemented by Regulation (EC) No. 847/2000 provides that a drug ff ing not more than five in ten thousand persons in the EU when the application is made, or (2) a life- can be designated as an orphan drug by the European Commission if its sponsor can establish: that the product is intended for the diagnosis, prevention or treatment of (1) a life-threat ening or chronically debilitating condition affect threatening, seriously debilitating or serious and chronic condition in the EU and that without incentives it is unlikely that the marketing of the drug in the EU would generate sufficff ient return to justify the necessary investment.

However, marketing authorization may be granted to a similar medicinal product with the same orphan indication during the 10-year period with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of the original orphan medicinal product is unable to supply sufficient same orphan indication if this product is saferff orphan medicinal product. The period of market exclusivity may, in addition, be reduced to six years if it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficient profitable not to justify maintenance of market exclusivity. quantities. Marketing authorization may also be granted to a similar medicinal product with the ive or otherwise clinically superior to the original , more effect ly ff ff ff Patent Term Extensions in the European Union and Other Jurisdic ii tions The European Union also provides for patent term extension through Supplementary Protection Certificates, or SPCs. The rules and requirements for obtaining a SPC are similar to those in the United States. An SPC may extend the term of a patent for up to five years after its originally scheduled expiration date and can provide up to a maximum of fifteen years of marketing exclusivity forff a drug. These periods can be extended for six additional months if pediatric exclusivity is obtained, which is described in detail below. Although SPCs are available throughout the European Union, sponsors must apply on a country-by-country basis. Similar patent term extension rights exist in certain other foreign jurisdictions outside the European Union. ll Regulatory ii Requiremen ts after a MarkMM etingtt Authorization has been Obtained In case an authorization for a medicinal product in the EU is obtained, the holder of the marketing authorization is required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of medicinal products. These include: • • • Compliance with the EU’s stringent pharmacovigilance or safety reporting rules must be ensured. These rules can impose post-authorization studies and additional monitoring obligations. The manufacturing of authorized medicinal products, for which a separate manufacturer mandatory, must also be conducted in strict compliance with the applicable EU laws, regulations and guidance, including Directive 2001/83/EC, Directive 2003/94/EC, Regulation (EC) No 726/2004 and the European Commission Guidelines for Good Manufacturing Practice. These requirements include compliance with EU cGMP standards when manufacturing medicinal products and active pharmaceutical ingredients, including the manufacture of active pharmaceutical ingredients outside of the EU with the intention to import the active pharmaceutical ingredients into the EU. ’s license is ff The marketing and promotion of authorized drugs, including industry-sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or the general public, are strictly regulated in the EU notably under Directive 2001/83EC, as amended, and are also subject to EU Member State laws. Direct-to-consumer advertising of prescription medicines is prohibited across the EU. Brexit and the Regulatory ll Frameworkww in the United Kingii dom The United Kingdom’s withdrawal from the EU took place on January 31, 2020. The EU and the United Kingdom reached an agreement on their new partnership in the Trade and Cooperation Agreement, or the Agreement, which was applied provisionally beginning on January 1, 2021 and which entered into forff ce on May 1, 2021. The Agreement focuses primarily on free trade by ensuring no tariffsff or quotas on trade in goods, , the EU and the United Kingdom will formff including healthcare products such as medicinal products. Thereafter two separate markets governed by two distinct regulatory and legal regimes. As such, the Agreement seeks to minimize barriers to trade in goods while accepting that border checks will become inevitable as a consequence that the United Kingdom is no longer part of the single market. As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or the MHRA, became responsible for supervising medicines and medical devices in Great Britain, comprising England, Scotland and Wales under domestic law whereas ff 59 Northern Ireland continues to be subject to EU rules under the Northern Ireland Protocol. The MHRA will rely on the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), or the HMR, as the basis for regulating medicines. The HMR has incorporated into the domestic law the body of EU law instruments governing medicinal products that pre-existed prior to the United Kingdom’s withdrawal from the EU. ff Furthermore, while the Data Protection Act of 2018 in the United Kingdom that “implements” and complements the European Union’s General Data Protection Regulation, or GDPR, has achieved Royal Assent ive in the United Kingdom, it is still unclear whether transfer of data from the on May 23, 2018 and is now effect European Economic Area, or EEA, to the United Kingdom will remain lawful under GDPR.

The GDPR also imposes strict rules on the transfer of personal data to countries outside the EU, including the U.S., and permits data protection authorities to impose large penalties for violations of the GDPR, including potential fines of up to €20 million or 4% of annual global revenues, whichever is greater. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. Compliance with the GDPR will be a rigorous and time-intensive process that may increase the cost of doing business or require companies to change their business practices to ensure full compliance. Prici rr ngii Decisioii ns for Approved Produ rr cts In the EU, pricing and reimbursement schemes vary widely from country to country. Some countries human use. EU Member States may approve a specific price for a product or it may provide that products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular product candidate to currently available therapies or so-called health technology assessments, in order to obtain reimbursement or pricing approval. For example, EU Member States have the option to restrict the range of products forff which their national health insurance systems provide reimbursement and to control the prices of medicinal products forff instead adopt a system of direct or indirect controls on the profitability of the company placing the product on the market. Other EU Member States allow companies to fix their own prices for products, but monitor and control prescription volumes and issue guidance to physicians to limit prescriptions. Recently, many countries in the EU have increased the amount of discounts required on pharmaceuticals and these efforts as countries attempt to manage health care expenditures, especially in light of the severe fiscal and debt crises experienced by many countries in the EU. The downward pressure on health care costs in general, particularly prescription products, has become intense. As a result, increasingly high barriers are being erected to the entry of new products.

We are still in the early stages of development of our product candidates, and we have not completed development of any product candidates. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. We anticipate that our expenses will increase substantially if and as we: • • • • • • • • • • continue a Phase 1/2 clinical trial of our product candidate bavdegalutamide (ARV-RR 110) and a Phase 1b clinical trial of bavdeglutamide in combination with abiraterone for the treatment of men with metastatic castration-resistant prostate cancer, or mCRPC, and initiate one or more additional Phase 1b cohort expansions of bavdegalutamide in combination with standard of care agents, in men with mCRPC; continue a Phase 1/2 clinical trial of our product candidate ARV-471 ARV-RR 471 in combination with palbociclib, and initiate an additional Phase 1b cohort expansion in combination with a standard of care agent, each in patients with locally advanced or metastatic ER positive / HER2 negative breast cancer and initiate a window of opportunity study in early breast cancer; and a Phase 1b clinical trial of VV continue a Phase 1 clinical trial of our product candidate ARV-766 a planned Phase 2 cohort expansion trial in 2022; VV in men with mCRPC, and initiate apply our PROTAC Discovery Engine to advance additional product candidates into preclinical and clinical development; expand the capabilities of our PROTACTT Discovery Engine; seek marketing approvals for any product candidates that successfully complete clinical trials; ultimately establish a sales, marketing and distribution infrastructure and scale up external manufacturing capabilities to commercialize any products forff which we may obtain marketing approval; expand, maintain and protect our intellectual property portfolio; hire additional development, including clinical and regulatory, and scientific personnel; and add operational, financial and management information systems and personnel to support our research, product development and future commercialization efforts a public company. and support our operations as ff Our expenses could increase beyond our expectations if we are required by the U.S. Food and Drug Administration, or FDA, the European Medicines Agency, or EMA, or other regulatory authorities to perform trials in addition to those that we currently expect, or if there are any delays in establishing appropriate manufacturing arrangements for or in completing our clinical trials or the development of any of our product candidates. Because of the numerous risks and uncertainties associated with pharmaceutical product development, we are unable to accurately predict the timing or amount of increased expenses we will incur or when, if ever, we will be able to achieve profitability. Even if we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis. Our failure to become and remain profitable would depress the value of our company and could impair our ability to raise capital, expand our business, maintain our research and development effort ur product offeri the value of our company could also cause our stockholders to lose all or part of their investment. ngs or even continue our operations. A decline in s, diversify off ff ff We have nevervv generated revenue from produ rr ct sales and may never be profita rr ble. We initiated clinical development of our first two product candidates in 2019 and initiated clinical development of our third product candidate in 2021 and we expect that it will be many years, if ever, before we have a product candidate ready for commercialization. We may never succeed in these activities and, even if we do, may never generate revenues that are significant enough to achieve profitability. To become and remain profitable, we must succeed in developing, obtaining marketing approval for and commercializing products that generate significant revenue. This will require us to be successful in a range of challenging activities, including 62 completing preclinical testing and clinical trials of our product candidates, discovering additional product candidates, establishing arrangements with third parties for the manufacture of clinical supplies of our product candidates, obtaining marketing approval for our product candidates and manufacturing, marketing and selling any products forff which we may obtain marketing approval. If one or more of the product candidates that we develop is approved for commercial sale, we anticipate incurring significant costs associated with commercializing any approved product candidate. Even if we are able to generate revenues from the sale of any approved products, we may not become profitable and may need to obtain additional funding to continue operations.

In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufactu distribution. We have incurred, and expect to continue to incur, additional costs associated with operating as a public company.

We believe that our cash, cash equivalents, restricted cash and marketable securities as of December 31, 2021 will enable us to fund our planned operating expenses and capital expenditure requirements multiple additional years beyond 2024. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including: • • • • • • • • • the progress, costs and results of our ongoing clinical trials for bavdegalutamide, ARV-RR 471 and ARV-RR 766 and any future clinical development of bavdegalutamide, ARV-RR 471 and ARV-RR 766; the scope, progress, costs and results of preclinical and clinical development for our other product candidates and development programs; the number of, and development requirements for, other product candidates that we pursue, including our other oncology and neurodegenerative research programs; the success of our collaborations with Pfizer, Inc., or Pfizer; Genentech, Inc. and F. Hoffmff an LaRoche Ltd., collectively referred to as Genentech; and Bayer AG, or Bayer; the costs, timing and outcome of regulatory review of our product candidates; the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; ff the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; and ff our ability to establish additional collaboration arrangements with other biotechnology or pharmaceutical companies on favorable terms, if at all, for the development or commercialization of our product candidates. 63 Identifying potential product candidates and conducting preclinical testing and clinical trials is a time- consuming, expensive and uncertain process that takes years to complete, and we may never generate the necessary data or results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved, may not achieve commercial success. Our commercial revenues, if any, will be derived from sales of products that we do not expect to be commercially available forff many years, if at all. Accordingly, we will need to obtain substantial additional funds to achieve our business objectives. Adequate additional funds may not be available to us on acceptable terms, or at all. In addition, we may seek additional capital due to favorable market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. ff g additidd onal capital may cause diluii tion to our stockholders, restri rr ct our operations or reqrr uireii us Raisinii to relinll quish righi ts to our technologies or prodrr uct candidates. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to rings, debt financings, collaborations, strategic finance our cash needs through a combination of equity offeff alliances and marketing, distribution or licensing arrangements. Although we may receive potential future payments under our collaborations with Pfizer, Genentech and Bayer, we do not currently have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our stockholders’ ownership interests will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect 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 acquisitions or capital expenditures or declaring dividends. our stockholders’ rights as common stockholders. ff If we raise additional funds through collaborations, strategic 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.

In 2019, we initiated our first Phase 1 clinical trial forff bavdegalutamide, and later in 2019 and 2021, we initiated our Phase 1 clinical trial of our product candidates ARV-RR 471 and ARV-RR 766, respectively. All of our other product candidates are still in preclinical development. We have not yet demonstrated our ability to successfully complete any clinical trials, obtain marketing approvals, manufacture a commercial scale product, or arrange for a third party to do so on our behalf, or conduct sales, marketing and distribution activities necessary for successful product commercialization. Consequently, any predictions stockholders make about our future success or viability may not be as accurate as they could be if we had a longer operating history. a product candidate, In addition, as a young business, we may encounter unforeff seen expenses, difficulties, complications, delays and other known and unknown factors. We will need to transition at some point from a company with a research and development focus to a company capable of supporting commercial activities. We may not be successful in such a transition. We expect our financial condition and operating results to continue to fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. Accordingly, stockholders should not rely upon the results of any quarterly or annual periods as indications of future operating performance. ff 64 tt The ongoing COVID-1VV tt t o init 9 pandemdd , disdd rupt regulatll ory activities or have other adverse current or future preclinical studies or clinical trialsrr this pandemic may continue effecff tt ddition, effects ott , whicww h could result in adverserr economies worldwide tt vv to adversely s and operations. n our busines ts on our business and operations ic has and may continue e and complete our ability t ff to affect impact .

The outbreak and government measures taken in response have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen.

For example, our New Haven-based laboratories were closed for part of March through May 2020 which limited the biology work we could conduct for our early-stage research programs and increased our reliance on CROs. We and our CROs and CMOs may face disruptions related to our ongoing clinical trials or future clinical trials arising from delays in investigational new drug, or IND,-enabling studies, manufacturing disruptions, and the ability to obtain necessary institutional review board or other necessary site approvals, as For example, in the first quarter well as other delays at clinical trial sites, including delays related to site staffing. of 2020, production of certain building blocks for the drug substance used in the manufacture of ARV-RR 471 were delayed at one of our China-based manufacturers. The response to the COVID-19 pandemic may redirect resources with respect to regulatory and intellectual property matters in a way that would adversely impact our ability to progress regulatory approvals and protect our intellectual property. In addition, we may face impediments to regulatory meetings and approvals due to measures intended to limit in-person interactions. ff ff ff The pandemic has already caused significant disruptions in the financial markets, and may continue to cause such disruptions, which could impact our ability to raise additional funds through public offerings also impact the volatility of our stock price and trading in our stock. Moreover, it is possible the pandemic will significantly impact economies worldwide, which could result in adverse effect s on our business and operations.

The TCJA contains, among other things, significant changes to corporate taxation, including a reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, the limitation of the tax deduction for net interest expense to 30% of adjusted earnings (except for certain small businesses), the limitation of the deduction for net operating losses to 80% of current-year taxable income and elimination of net operating loss carrybacks, in each case, for losses arising in taxable years beginning after December 31, 2017 (though any such net operating losses may be carried forward indefinitely and such net operating losses arising in taxable years beginning before January 1, 2021 are generally eligible to be carried back up to five years), the imposition of a one-time taxation of offshore elimination of U.S. tax on foreign earnings (subject to certain important exceptions), the allowance of immediate deductions for certain new investments instead of deductions for depreciation expense over time, and the modification or repeal of many business deductions and credits. earnings at reduced rates regardless of whether they are repatriated, the ff In addition to the CARES Act, as part of Congress’s response to the COVID-19 pandemic, economic relief legislation has been enacted in 2020 and 2021 containing tax provisions.

Also, as a result of the changes in the U.S. presidential administration and control of the U.S. Senate in 2021, additional tax legislation may be enacted; any such additional legislation could have an impact on our company.

In addition, under Section 382 of the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership by certain stockholders over a three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset limited. We believe our federal net operating losses are subject to an annual limitation as a result of changes in the Company’s ownership, as defined by Code Section 382, in July 2018 and December 2020. Notwithstanding the limitations, we expect the federal net operating losses to be fully available under Section 382 within the next two years, subject in the future as a result of subsequent changes in our stock ownership, some of which may be outside of our control. If we determine that an ownership change has occurred and our ability to use our historical net operating loss and tax credit carryforwards is materially limited, it would harm our future operating results by effect to any other limitations under the Code.

In addition, initial success in clinical trials may not be indicative of results obtained when such trials are completed. In particular, the small number of patients in our ongoing early clinical trials may make the results of these trials less predictive of the outcome of later clinical trials. For example, even if successful, the results of the dose- escalation or expansion portions of our Phase 1/2 clinical trials of bavdegalutamide and ARV-RR 471 and our Phase 1 clinical trial of ARV-RR 766 may not be predictive of the results of further clinical trials of these product candidates or any of our other product candidates. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing performed approval of their products. Our current or future clinical trials may not ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for product candidates proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffere d significant setbacks in clinical development even after achieving encouraging results in earlier studies. Any such setbacks in our clinical development could materially harm our business and results of operations. ff ff 69 top-lineii Interimrr and prelrr time may change as more patient datdd a btt procedu inary data fromrr imll rr res that could result in materialii changes in the final data.tt our clinical trialsrr that weww announce or publish fromff time to ecome availab vv le and are subject to auditdd and verivv fication From time to time, we may publish interim top-line or preliminary data from our clinical trials. Interim data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. For example, the initial safety, tolerability, pharmacokinetic and effiff cacy data that we have disclosed in connection with our ongoing Phase 1/2 clinical trials of bavdegalutamide and ARV-RR 471 may not be indicative of the full results of those trials obtained upon completion. Preliminary or top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, ff interim and preliminary data should be viewed with caution until the final data are available.

In particular, we are conducting a Phase 1/2 clinical trial of bavdegalutamide for men with mCRPC, a Phase 1/2 clinical trial of ARV-RR 471 for patients with locally advanced or metastatic ER positive / HER2 negative breast cancer, and a Phase 1 clinical trial of ARV-RR 766 for men with mCRPC. We cannot predict how difficult Therefore, our ability to identify and enroll eligible patients for bavdegalutamide, ARV-RR 471 and ARV-RR 766 clinical trials may be limited or may result in slower enrollment than we anticipate. In addition, some of our competitors have ongoing clinical trials for product candidates that treat the same indications as our product candidates, and patients who would otherwise be eligible forff competitors’ product candidates. Patient enrollment is affect our clinical trials may instead enroll in clinical trials of our ed by other factors including: it will be to enroll patients forff trials in these indications. ff ff • • • • • • • • • the severity of the disease under investigation; the eligibility criteria forff the trial in question; the perceived risks and benefits of the product candidates under study; ff the effort ff s to facilit ate timely enrollment in clinical trials; the availability of competing therapies; the patient referral ff practices of physicians; the burden on patients due to inconvenient procedures; the ability to monitor patients adequately during and after treatment; and the proximity and availability of clinical trial sites for prospective patients. In April 2020, we announced that, as a result of the COVID-19 pandemic, two trial sites for our ongoing Phase 1/2 clinical trial of bavdegalutamide had publicly announced pauses in patient enrollment for clinical trials, including our trials. In addition, one trial site for our ongoing Phase 1/2 clinical trial of ARV-RR 471 had a pause in patient enrollment for clinical trials, including our trial. While the pauses at each of the trial sites have been liftedff clinical trials if patients are affect clinical trial sites because of the outbreak. For example, we experienced a short delay in the enrollment forff cohort of our ARV-471 , we may nonetheless face difficulties recruiting or retaining patients in our ongoing and planned l of traveling to, or are unable to travel to, our trial as a result of screening slowdowns attributable to COVID-19. ed by the virus or are fearfurr VV ff one Our inability to enroll a sufficff ient number of patients forff our clinical trials would result in significant delays and could require us to abandon one or more clinical trials altogether. Enrollment delays in our clinical trials may result in increased development costs for our product candidates, which would cause the value of our company to decline and limit our ability to obtain additional financing. 70 We may expend our limll capitaltt greater likll elihood izll e on product candidates or indic of success. ll ii ited resources to pursue a particul rr ations tt that may be more prr arll prodrr uct candidate or indicationtt rofitable or for which ther and fail ff rr s aii e i tt to Because we have limited financial and managerial resources, we focuff s on research programs and product candidates that we identify for specific indications. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may relinquish valuable rights to that product candidate through collaboration, licensing or other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate. evel oping and may continuii dd We are drr drugs.

For example, in the fouff expansion with ARV-471 negative breast cancer for use in combination with palbociclib, a CDK4/6 inhibitor that is currently approved for the treatment of patients with breast cancer, and in the fourth quarter of 2021, we initiated a Phase 1b clinical trial of bavdegalutamide for the treatment of men with mCRPC in combination with abiraterone, a hormone therapy drug that is currently approved for the treatment of patients with prostate cancer. We did not develop or obtain marketing approval for, nor do we manufacture or sell, any of the currently approved drugs that we are or may study in combination with bavdegalutamide or ARV-RR 471. If the FDA or similar regulatory authorities outside of the United States revoke their approval of the drug or drugs in combination with which we determine to develop ARV-RR 471, we will not be able to market bavdegalutamide or ARV-RR 471 in combination with such revoked drugs. If safety or efficff acy issues arise with any of these drugs, we could experience significant regulatory delays, and the FDA or similar regulatory authorities outside of the United States may require us to redesign or terminate the applicable clinical trials. If the drugs we use are replaced as the standard of care for the indications we choose for bavdegalutamide or ARV-RR 471, the FDA or similar regulatory authorities outside of the United States may require us to conduct additional clinical trials. In addition, if manufacturing or other issues result in a shortage of supply of the drugs with which we determine to combine with bavdegalutamide or ARV-RR 471, we may not be able to complete clinical development of bavdegalutamide or ARV-RR 471 on our current timeline or at all. Even if bavdegalutamide or ARV-RR 471 were to receive marketing approval or be commercialized for use in combination with other existing drugs, we would continue to be subject to the risks that the FDA or similar regulatory authorities outside of the United States could revoke approval of the drug used in combination with bavdegalutamide or ARV-RR 471 or that safety, efficacy, manufacturing or supply issues could arise with these existing drugs. Combination therapies are commonly used for the treatment of cancer, and we would be subject to similar risks if we develop any of our other product candidates for use in combination with other drugs or for indications other than cancer. This could result in our own products being removed from the market or being less successful commercially. We may not be successful in oii ur efforts to identi dd fy or discii over additional potentialii prodrr uct candidates. A key element of our strategy is to apply our PROTACTT Discovery Engine to address a broad array of targets and new therapeutic areas. The therapeutic discovery activities that we are conducting may not be successful in identifying product candidates that are useful in treating cancer or other diseases. Our research 71 programs may initially show promise in identifying candidates for clinical development for a number of reasons, including: ff potential product candidates, yet fail to yield product • • potential product candidates may, on further study, be shown to have harmful side effect characteristics that indicate that they are unlikely to be drugs that will receive marketing approval or achieve market acceptance; or s or other ff potential product candidates may not be effeff ctive in treating their targeted diseases. Research programs to identify new product candidates require substantial technical, financial and and resources on a potential product candidate that human resources. We may choose to focus our efforts ultimately proves to be unsuccessful. If we are unable to identify suitable product candidates for preclinical and clinical development, we will not be able to obtain revenues from sale of products in future periods, which likely would result in significant harm to our financial position and adversely impact our stock price. ff We face substantial competitiott n, which may result in others commerciali tt g products before or more successfully t discoii l hatt n we dww o. zinii ii veringii , dgg eveloping or The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary products. We face and will continue to face competition from third parties that use protein degradation, antibody therapy, inhibitory nucleic acid, gene editing or gene therapy development platforms and from companies focused on more traditional therapeutic modalities, such as small molecule inhibitors. The competition is likely to come from multiple sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, government agencies and public and private research institutions. We are aware of several biotechnology companies focused on developing chimeric small molecules for protein degradation including Accutar Biotechnology, Inc., C4 Therapeutics, Inc., Cullgen Inc., Foghorn Therapeutics, Inc., Kymera Therapeutics, Inc., Nurix Therapeutics, Inc. and Proteovant Therapeutics, Inc. Further, several large pharmaceutical companies have disclosed preclinical investments in this field, including AbbVie, Amgen Inc., AstraZeneca plc, Boehringer Ingelheim, Bristol Myers Squibb Company, GlaxoSmithKline plc, Genentech, Novartis International AG and Sanofi SA. Since 2020, some of these biotechnology and pharmaceutical companies have announced the initation of clinical trials for targeted protein degraders. Many of our current or potential competitors, either alone or with their collaboration partners, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved products than we do. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are saferff more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position beforeff market. In addition, our ability to compete may be affected in many cases by insurers or other third-party payors seeking to encourage the use of generic products. There are generic products currently on the market for certain of the indications that we are pursuing, and additional products are expected to become available on a generic basis over the coming years. If our product candidates are approved, we expect that they will be priced at a significant premium over competitive generic products. ive, have fewer or less severe side effect we are able to enter the , more effect s, are ff ff 72 If our collaboll potential of ARV-471. ration witww h Ptt VV Risks Related to Dependence on Third Parties fizer is not successful, we may not be able to capitalizeii on the market In July 2021, we entered into a collaboration agreement with Pfizer, or the ARV-RR 471 Collaboration Agreement, pursuant to which we granted Pfizer worldwide coexclusive rights to develop and commercialize products containing our proprietary compound ARV-RR 471, or the Licensed Products. Although pursuant to the terms of the ARV-RR 471 Collaboration Agreement, we and Pfizer will share equally (50/50) all development costs, including costs forff conducting clinical trials, for the Licensed Products, subject to certain exceptions, our control over the amount and timing of resources that Pfizer dedicates to the development or commercialization of the Collaboration Agreement will Licensed Products is limited. Our ability to generate revenues from the ARV-471 depend, in part, on Pfizer’s ability to successfully performff the functions assigned to it in such agreement. We cannot predict the success of this collaboration with Pfizer, and we cannot guarantee that this collaboration will lead to development or commercialization of the Licensed Products in the most effiff cient manner or at all. VV If this collaboration with Pfizer does not result in the successful development and commercialization of Licensed Products, or if Pfizer terminates the ARV-471 convenience subject to certain notice periods, we may not receive any of the $1.4 billion in contingent payments based on specified regulatory and sales-based milestones for the Licensed Products under the ARV-RR 471 Collaboration Agreement.

If on the market potential of We currently have, and anticipate in the future seeking additional, third-party collaborators for the research, development, and commercialization of some of our PROTAC programs. For example, in September 2015 we entered into a research collaboration with Genentech, which we amended and restated in November 2017; in December 2017 we entered into a research collaboration with Pfizer; in July 2019 we entered into a research collaboration with Bayer; and in July 2021 we entered into a development and commercialization collaboration with Pfizer. Our likely collaborators for any other collaboration arrangements include large and mid-size pharmaceutical companies and biotechnology companies. Any such arrangements with third parties will likely limit our control over the amount and timing of resources that our collaborators dedicate to the development or commercialization of any product candidates we may seek to develop with them. Our ability to generate revenues from these arrangements will depend on our collaborators’ abilities to successfully performff the functions assigned to them in these arrangements. We cannot predict the success of any collaboration that we enter into. Collaborations involving our research programs or any product candidates we may develop, including our collaborations with Pfizer, Genentech and Bayer, pose the following risks to us: • • Collaborators have significant discretion in determining the efforts to these collaborations. For example, our collaboration with Genentech is managed by a joint research committee and joint project team, which is composed of representatives from us and Genentech, with Genentech having final decision-making authority. Similarly, our research collaborations with Pfizer and Bayer are managed by joint research committees composed of an equal number of representatives from us and our collaborative partner, with our collaborative partner having final decision-making authority. and resources that they will apply ff Collaborators may not pursue development and commercialization of any product candidates we may develop or may elect not to continue or renew development or commercialization programs based on clinical trial results, changes in the collaborator’s strategic focus or available funding or external factors such as an acquisition or business combination that diverts resources or creates competing priorities. • Genentech, Pfizer and Bayer have broad rights to select any target for protein degradation development on an exclusive basis, even as to us, so long as not excluded by us under the terms 73 • • • • • of each collaboration and may select targets we are considering but have not taken sufficient action to exclude under the collaboration. ent funding for a clinical trial program, stop a Collaborators may delay clinical trials, provide insuffici clinical trial or abandon a product candidate, repeat or conduct new clinical trials, or require a new formulation of a product candidate forff clinical testing. ff Collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our products or product candidates if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are more economically attractive than ours.

For example, each of Genentech, Pfizer and Bayer can terminate its agreement with us in its entirety or with respect to a specific target for convenience subject to specified notice periods, in certain cases as short as 60 days, or in connection with a material breach of the agreement by us that remains uncured for a specified period of time.

If a present or future collaborator of ours were to be involved ff If our collaborations do not result in the successful development and commercialization of products, or if one of our collaborators terminates its agreement with us, we may not receive any future research funding or milestone or royalty payments under the collaboration. If we do not receive the funding we expect under these agreements, our development of product candidates could be delayed, and we may need additional resources to develop product candidates. In addition, if one of our collaborators terminates its agreement with us, we may to find a suitable replacement collaborator or attract new collaborators, and our development find it more difficult programs may be delayed or the perception of us in the business and financial communities could be adversely affecte d. All of the risks relating to product development, marketing approval, and commercialization described in this Annual Report on Form 10-K apply to the activities of our collaborators. ff ff We may in the future decide to collaborate with pharmaceutical and biotechnology companies for the development and potential commercialization of any product candidates we may develop. These relationships, or those like them, may require us to incur non-recurring and other charges, increase our near- and long-term expenditures, issue securities that dilute our existing stockholders, or disrupt our management and business. In addition, we could face significant competition in seeking appropriate collaborators, and the negotiation process is time-consuming and complex. Our ability to reach a definitive collaboration agreement will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration, and the proposed collaborator’s evaluation of several factors. If we license rights to 74 any product candidates we or our collaborators may develop, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture.

We face significant competition in attracting appropriate collaborators to advance the development of any product candidates for which we may seek a collaboration. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical trials, the likelihood of approval by the FDA or other regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, the terms of any existing collaboration agreements, and industry and market conditions generally. The collaborator may also have the similar indications and will have to opportunity to collaborate on other product candidates or technologies forff evaluate whether such a collaboration could be more attractive than one with us. Collaborations are complex and time-consuming to negotiate, document and execute. In addition, consolidation among large pharmaceutical companies has reduced the number of potential future collaborators. Our existing collaboration agreements limit our ability to enter into future agreements on certain terms with potential collaborators. For example, we have granted exclusive rights to Genentech, Pfizer and Bayer for the discovery, development and commercialization of PROTAC targeted protein degraders directed to certain protein targets, and during the terms of those agreements, we will be restricted from granting rights to other parties to use our PROTAC technology for those targets. Any collaboration we enter into may limit our ability to enter into future agreements on particular terms or covering similar target indications with other potential collaborators. We may not be able to negotiate collaborations on a timely basis, on acceptable terms or at all. If we are unable to do so, we may have to curtail the development of the product candidate forff which we are seeking to collaborate, reduce or delay its development program or one or more of our other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop our product candidates or bring them to market and generate revenue from product sales, which could have an adverse effect on our business, prospects, financial condition and results of operations. ff nd expect to continuii satistt may not performrr e to relyrr factorilrr y,l We rely al parties rr trials. on third parties to conduct our clini to meet deadlines includingii failiii ngii ii ii cal trialsrr , and those thirdii for the completiontt of such We rely and expect to continue to rely on third-party CROs to conduct our Phase 1/2 clinical trial for bavdegalutamide, our Phase 1/2 clinical trial for ARV-RR 471, our Phase 1 clinical trial forff ARV-RR 766 and any other planned clinical trials and currently do not plan to independently conduct any clinical trials of bavdegalutamide, ARV-RR 471 and ARV-RR 766 or of our other product candidates.

If we need to enter into alternative Our reliance on these third parties for research and development activities reduces our control over these activities but does not relieve us of our responsibilities. For example, we will remain responsible forff ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols in the applicable IND. Moreover, the FDA requires compliance with standards, commonly referred to as good clinical practices, or GCPs, for conducting, recording and reporting the results of clinical trials to assure 75 that data and reported results are credible and accurate and that the rights, integrity and confidentiality of trial participants are protected. Furthermore, these third parties may have relationships with other entities, some of which may be our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for our product candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our product candidates. ff rty contract ii rr manufacturing organi zatio We rely on third-pa ii substance and finished drugrr and expect to continuii risk that we willii not have sufficient quantities of our product candidates or produ at an acceptable cost or quality, wyy commercializa dd tion.

We have only limited technology transfer agreements in place with respect to our product candidates, and these arrangements do not extend to commercial supply. We acquire many key materials on a purchase order basis. As a result, we do not have long term committed arrangements with respect to our product candidates and other materials. If we receive marketing approval for any of our product candidates, we will need to establish an agreement for commercial manufacture with a third party. Third-party manufacturers may not be able to comply with current good manufacturing practices, or cGMP, rP egulations or similar regulatory requirements outside of the United States. Our failure, or the failure of our third-party manufactu us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of product candidates or products, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect rers, to comply with applicable regulations could result in sanctions being imposed on supplies of our products. ff ff Our product candidates and any products that we may develop may compete with other product candidates and products for access to manufacturing facilities. As a result, we may not obtain access to these facilities on a priority basis or at all. There are a limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. ff Any performance failure on the part of our existing or future manufacturers could delay clinical development or marketing approval. Some of our manufacturers are based outside of the United States, including the manufacturers As a result of the COVID-19 pandemic, there has been an increased risk of supply interruption with our manufacturers and, in the first quarter of 2020, the production of certain building blocks for the drug substance used in the manufacture of ARV-RR 471 was delayed at one of our China-based manufacturers.

For example, current cancer treatments, such as chemotherapy and radiation therapy, are well established in the medical community, and doctors may continue to rely on these treatments. If our product candidates do not achieve an adequate level of acceptance, we may not generate significant revenue from product sales and we may not become profitable. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number of factors, including: • • • • • • • • • • ff the efficacy and potential advantages compared to alternative treatments; the prevalence and severity of any side effect ff s, in particular compared to alternative treatments; our ability to offeff r our products for sale at competitive prices; the convenience and ease of administration compared to alternative treatments; the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; the strength of marketing, sales and distribution support; the availability of third-party coverage and adequate reimbursement; the timing of any marketing approval in relation to other product approvals; support from patient advocacy groups; and any restrictions on the use of our products together with other medications.

To achieve commercial success for any product for which we obtain marketing approval, we will need to establish sales, marketing and distribution capabilities, either ourselves or through collaboration or other arrangements with third parties. We currently expect that we would build our own focused, specialized sales and marketing organization to support the commercialization in the United States of product candidates for which we receive marketing approval and that can be commercialized with such capabilities. There are risks involved with establishing our own sales and marketing capabilities. For example, recruiting and training a sales force is expensive and time- consuming and could delay any product launch.

Current and future legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares the cost- effect iveness of our product candidate to other available therapies. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenues, if any, we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if our product candidates obtain marketing approval. Our ability to commercialize any product candidates successfully also will depend in part on the extent these products and related treatments will be available from to which coverage and adequate reimbursement forff government healthcare programs, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement forff government authorities and third-party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Coverage and reimbursement may not be available for any product that we commercialize and, even if these are available, the level of reimbursement may not be satisfactory. Reimbursement may affect the demand for, or the price of, any product candidate forff which we obtain marketing approval.

If we cannot successfully defend ourselves against claims that our product candidates or products caused injuries, we will incur substantial liabilities. Regardless of merit or eventual outcome, liability claims may result in: • • • • • • • • • • decreased demand for any product candidates or products that we may develop; termination of clinical trials; withdrawal of marketing approval, recall, restriction on the approval or a “black box” warning or contraindication for an approved drug; withdrawal of clinical trial participants; significant costs to defendf the related litigation; substantial monetary awards to trial participants or patients; loss of revenue; injury to our reputation and significant negative media attention; reduced resources of our management to pursue our business strategy; and the inability to commercialize any products that we may develop. We currently hold $10.0 million in product liability insurance coverage in the aggregate, with a per incident limit of $10.0 million, which may not be adequate to cover all liabilities that we may incur. We will need to increase product liability insurance coverage as we expand our clinical trials and if we commence commercialization of our product candidates. Insurance coverage is increasingly expensive. We may not be able to maintain insurance coverage at a reasonable cost or in an amount adequate to satisfy any liability that may arise.

We seek to protect our proprietary position by filing patent applications in the United States and abroad related to our novel technologies and product candidates. Any disclosure to or misappropriation by third parties of our confidential proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, thus eroding our competitive position in our market. Moreover, the patent applications we own, co-own or license may fail to result in issued patents in the United States or in other foreign countries. The patent prosecution process is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify patentable aspects of our research and development output beforeff it is too late to obtain patent protection. Moreover, in some circumstances, we do not have the right to control the preparation, filing and prosecution of patent applications, or to maintain the patents, covering technology that we license from third parties. Therefore, these patents and applications may not be prosecuted and enforced a manner consistent with the best interests of our business. ff ff in The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions and has in recent years been the subject of much litigation. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States. For example, European patent law restricts the patentability of methods of treatment of the human body more than United States law does. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, whether we were the first to make the inventions claimed in our owned, co-owned or licensed patents or pending patent applications, or that we were the first inventors to file for patent protection of such inventions. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights are highly uncertain. Our pending and future patent applications may not result in patents being issued which protect our technology or products, in whole or in part, or which effecti ff technologies and products. Changes in either the patent laws or interpretation of the patent laws in the United States and other countries may diminish the value of our patents or narrow the scope of our patent protection. vely prevent others from commercializing competitive we cannot know with certainty ff Moreover, we may be subject to a third-party preissuance submission of prior art to the United States or the USPTO, or in addition to interference proceedings, may become involved review, post-grant review or other post-grant proceedings Patent and Trademark Office, ff in opposition, derivation, reexamination, intii er partesrr challenging our or our licensors’ patent rights or the patent rights of others. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, allow third parties to commercialize our technology or products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to license, develop or commercialize current or future product candidates. Our owned, co-owned and licensed patent estate includes patent applications, many of which are at an early stage of prosecution.

On September 16, 2011, the Leahy- Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith Act includes a the way number of significant changes to United States patent law. These changes include provisions that affect patent litigation.

Accordingly, it is not clear what, if any, impact the Leahy-Smith Act will have on the operation of our business.

In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained.

Competitors may infringe our issued patents, the patents of our licensors, or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive, time-consuming and unpredictable. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents. In addition, in a patent infringement proceeding, a court may decide that a patent of ours or our licensors is invalid or unenforceable, whole or in part, construe the patent’s claims narrowly or refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation proceeding could put one or more of our patents at risk of being invalidated, held unenforceable or interpreted narrowly.

More established companies may have a competitive advantage over us due to their larger size and cash resources or greater clinical development and commercialization capabilities.

Third parties may assert infringement intellectual property rights with respect to our products and technology, including interference, derivation, reexamination or inter parterr s review proceedings beforeff claims against us based on existing patents or patents that may be granted in the future. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may give rise to claims of infringement of the patent rights of others. There may be third-party patents of which we are currently unaware with claims to materials, formulations, methods of manufacture or methods for treatment related to the use or manufacture of our drug candidates. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. ff If we are found by a court of competent jurisdiction to infringe a third party’s intellectual property rights, we could be required to obtain a license from such third party to continue developing and marketing our products and technology.

Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. We could be forcff cease commercializing the infringing technology or product. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business.

While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of a patent or patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to offiff cial actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents.

Similar patent term extension also may be available in certain foreign countries upon regulatory approval of our product candidates.

We have not obtained marketing approval for any product candidate and it is possible that none of our existing product candidates, or any product candidates we may seek to develop in the future will ever obtain marketing approval. Our product candidates could fail to receive marketing approval for many reasons, including the following: • • • • • • • • the FDA may disagree with the design or implementation of our clinical trials; we may be unable to demonstrate to the satisfaction of the FDA that a product candidate is safef ff and effect ive for its proposed indication; results of clinical trials may not meet the level of statistical significance required by the FDA for approval; we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its safety risks; the FDA may disagree with our interpretation of data from preclinical studies or clinical trials; data collected from clinical trials of our product candidates may not be sufficient submission of a New Drug Application, or NDA, to the FDA or other submission or to obtain marketing approval in the United States; to support the ff the FDA may find deficiencies with or fail to approve the manufacturing processes or facilities of third-party manufactu rers with which we contract for clinical and commercial supplies; and ff the approval policies or regulations of the FDA may significantly change in a manner rendering our clinical data insufficient for approval. ff This lengthy approval process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval to market any of our product candidates, which would significantly harm our business, results of operations and prospects. The FDA has substantial discretion in the approval process, and determining when or whether regulatory approval will be obtained for any of our product candidates. Even if we believe the data collected from clinical trials of our product candidates are promising, such data may not be sufficient to support approval by the FDA. ff In addition, even if we were to obtain approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request, may not approve the price we intend to charge for our products, may grant approval contingent on the performance of costly post-marketing clinical trials, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the foregoing scenarios could materially harm the commercial prospects forff our product candidates.

Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate. We have not submitted an application forff approval for any of our product candidates in the United States or in any other jurisdiction. or received marketing As a company, we do not have experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third-party clinical research organizations or other third-party consultants or vendors to assist us in this process. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting informat indication to establish the product candidate’s safetyf ion about the product manufacturing process to, and inspection of manufacturing the submission of informat facilities by, the regulatory authorities. Our product candidates may not be effective, may be only moderately effect s, toxicities or other characteristics that may preclude our obtaining marketing approval or prevent or limit commercial use.

Securing marketing approval also requires ive or may prove to have undesirable or unintended side effect ff and efficacy ff ff ff ff The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application. Regulatory authorities have substantial discretion in the approval process and may for approval and require additional refuse to accept any application or may decide that our data is insufficient preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit or prevent marketing approval of a product candidate. Any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable. ff If we experience delays in obtaining approval or if we fail to obtain approval of our product candidates, our product candidates may be harmed and our ability to generate revenues will the commercial prospects forff be materially impaired.

The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The marketing approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. We, and any collaborators, may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. ff In many countries outside the United States, a product candidate must also be approved for reimbursement before it can be sold in that country. In some cases, the price that we intend to charge for our products, if approved, is also subject to approval. Obtaining non-U.S. regulatory approvals and compliance with non-U.S. regulatory requirements could result in significant delays, difficulties and costs for us and any collaborators and could delay or prevent the introduction of our product candidates in certain countries. In addition, if we or any collaborators fail to obtain the non-U.S. approvals required to market our product candidates outside the United States or if we or any collaborators fail to comply with applicable non-U.S. regulatory requirements, our target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed and our business, financial condition, results of operations and prospects may be adversely affect ed. ff 87 Additionally, we could face heightened risks with respect to seeking marketing approval in the United Kingdom as a result of the withdrawal of the United Kingdom from the EU, commonly referred to as Brexit. The United Kingdom is no longer part of the European Single Market and European Union Customs Union. As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency, or the MHRA, became responsible for supervising medicines and medical devices in Great Britain, comprising England, Scotland and Wales under domestic law, whereas Northern Ireland will continue to be subject to European Union rules under the Northern Ireland Protocol. The MHRA will rely on the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), or the HMR, as the basis for regulating medicines. The HMR has been incorporated into the domestic law of the body of European Union law instruments governing medicinal products that pre-existed prior to the United Kingdom’s withdrawal from the European Union. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, may force us to restrict or delay efforts to seek regulatory approval in the United Kingdom for our product candidates, which could significantly and materially harm our business. ff We expect that we will be subject to additional risks in commercializing any of our product candidates that receive marketing approval outside the United States, including tariffs, requirements; economic weakness, including inflation, or political instability in particular foreign economies and markets; compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country; and workforce uncertainty in countries where labor unrest is more common than in the United States. trade barriers and regulatory ff ff for thett or other tt p aii rr ey leadershi tt in a timely zedii Inadequate fundingii shut downs,ww retain kii commerciali business functions on which thett business. ii FDA,DD the SEC and other government agencies, incii disrii uprr tions to these agencies’ operations, could hinder their rr tt nd other manner or otherwi personnel, preven tt prevent thott ludingii tt se agencies from performingii fromrr abilitll y t seii t new products and services from being developed or government t o hire arr nd operation of our business may rely,l which could negatively i act our normal l mpii The ability of the FDA to review and approve new products can be affect ff ed by a variety of factors, ff including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes.

In addition, government funding of the SEC and other government ff Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations. ff ff Separately, in response to the COVID-19 pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. As of May 26, 2021, the FDA noted it was continuing to ensure timely reviews of applications for medical products during the ongoing COVID-19 pandemic in line with its user fee performff ance goals and conducting mission critical domestic and foreign inspections to ensure compliance of manufacturing facilities with FDA quality standards. However, the FDA may not be able to continue its current pace and review timelines could be extended, including where a pre-approval inspection or an inspection of clinical sites is required and due to the ongoing COVID-19 pandemic and travel restrictions, the FDA is unable to complete such required inspections during the review period. Regulatory authorities outside the U.S. may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic and may experience delays in their regulatory activities. If a prolonged government shutdown or other disruption occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our ff 88 business.

A Breakthrough Therapy product is defined as a product that is intended, alone or in combination with one or more other products, to treat a serious condition, and preliminary clinical evidence indicates that the product 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 products that have been designated as Breakthrough Therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffect ive control regimens. ff ff The FDA may also designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track products, sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’s application beforeff the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a Fast Track product may be effect ive. ff We may also seek a priority review designation for one or more of our product candidates.

A priority review adequate therapy exists, the FDA may designate the product candidate forff 89 designation means that the goal for the FDA to review an application is six months, rather than the standard review period of ten months. These designations are within the discretion of the FDA. Accordingly, even if we believe that one of our product candidates meets the criteria for these designations, the FDA may disagree and instead determine not to make such designation. Further, even if we receive a designation, the receipt of such designation for a product candidate may not result in a faster development or regulatory review or approval process compared to products considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA, including the Fast Track designation we received in May 2019 for bavdegalutamide for mCRPC. In addition, even if one or more of our product candidates qualifies for these designations, the FDA may later decide that the product candidates no longer meet the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

These requirements include submissions of safety and other post-marketing informat reports, registration and listing requirements, cGMP requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval, including the requirement to implement a risk evaluation and mitigation strategy. New cancer drugs frequently are indicated only for patient populations that have not responded to an existing therapy or have relapsed.

Globally, ion worldwide is rapidly evolving and is likely to remain uncertain for the foreseeable of informat ff virtually every jurisdiction in which we operate has established its own data security and privacy frameworks with which we must comply. For example, the collection, use, disclosure, transfer, or other processing of personal data regarding individuals in the European Union, including personal health data, is subject to the EU General Data Protection Regulation, or the GDPR, which took effect across all member states of the European Economic Area, or EEA, in May 2018. The GDPR is wide-ranging in scope and imposes numerous requirements on companies that process personal data, including requirements relating to processing health and other sensitive data, obtaining consent of the individuals to whom the personal data relates, providing informat ion to individuals regarding data processing activities, implementing safeguards to protect the security and confidentiality of personal data, providing notification of data breaches, and taking certain measures when engaging third-party processors. The GDPR increases our obligations with respect to clinical trials conducted in the EEA by expanding the definition of personal data to include coded data and requiring changes to informed consent practices and more detailed notices for clinical trial subjects and investigators. In addition, the GDPR also imposes strict rules on the transfer of personal data to countries outside the European Union, including the United States and, as a result, increases the scrutiny that clinical trial sites located in the EEA should apply to transfers of personal data from such sites to countries that are considered to lack an adequate level of data protection, such as the United States. The GDPR also permits data protection authorities to require destruction of improperly gathered or used personal informat ion and/or impose substantial fines for violations of the GDPR, which can be up to four percent of global revenues or 20 million Euros, whichever is greater, and it also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR. In addition, the GDPR provides that EU member states may make their own further laws and regulations limiting the processing of personal data, including genetic, biometric or health data. ff ff Similar actions are either in place or under way in the United States. There are a broad variety of data agencies at both the state protection laws that are applicable to our activities, and a wide range of enforcement and federal levels that can review companies for privacy and data security concerns based on general consumer protection laws. The Federal Trade Commission and state Attorneys General all are aggressive in reviewing privacy and data security protections for consumers. New laws also are being considered at both the state and federal levels. For example, the California on ff January 1, 2020, is creating similar risks and obligations as those created by the GDPR, though CCPA dPP exempt certain informat Human Subjects (the Common Rule). Many other states are considering similar legislation. A broad range of legislative measures also have been introduced at the federal level. Accordingly, failure to comply with federal and state laws (both those currently in effecff t and future legislation) regarding privacy and security of personal ion could expose us to fines and penalties under such laws. There also is the threat of consumer class informat actions related to these laws and the overall protection of personal data. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our reputation and our business.

The GDPR and other changes in laws or regulations associated with the enhanced protection of certain types of sensitive data, such as healthcare data or other personal informat ion from our clinical trials, could require us to change our business practices and put in place additional compliance mechanisms, may interrupt or delay our development, regulatory and commercialization activities and increase our cost of doing business, and could lead to government actions, private litigation and significant fines and penalties against us and could have a material enforcement adverse effect on our business, financial condition or results of operations.

Cost reduction initiatives and other provisions of this statute could decrease the coverage and price that we receive for any approved products. While the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in reimbursement that results from the MMA may result in a similar reduction in payments from private payors. In March 2010, then-President Obama signed Care Act, as amended by the Health Care and Education into law the Patient Protection and Affordable Affor dability Reconciliation Act, or collectively the ACA. In addition, other legislative changes have been ff proposed and adopted since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs.

For example, with enactment of the Tax Cuts for Jobs Act, or TCJA, in 2017, Congress repealed the “individual mandate.” The repeal of this provision, which requires most Americans to carry a minimal level of health insurance, became effecti December 14, 2018, a U.S. District Court judge in the Northern District of Texas ruled that the individual mandate portion of the ACA is an essential and inseverable feature of the ACA and thereforeff mandate was repealed as part of the TCJA, the remaining provisions of the ACA are invalid as well. The U.S. Supreme Court heard this case on November 10, 2020 and on June 17, 2021, dismissed this action after finding that the plaintiffsff do not have standing to challenge the constitutionality of the ACA. Litigation and legislation over the ACA are likely to continue, with unpredictable and uncertain results. ve in 2019. Further, on because the ff 94 The Trump Administration also took executive actions to undermine or delay implementation of the ACA, including directing federal agencies with authorities and responsibilities under the ACA to waive, deferff , grant exemptions from, or delay the implementation of any provision of the ACA that would impose a fiscal or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of pharmaceuticals or medical devices. On January 28, 2021, however, President Biden rescinded those orders and issued a new Executive Order which directs federal agencies to reconsider rules and other policies that limit Americans’ access to health care, and consider actions that will protect and strengthen that access. Under this Order, federal agencies are directed to re-examine: policies that undermine protections for people with pre- existing conditions, including complications related to COVID-19; demonstrations and waivers under Medicaid and the ACA that may reduce coverage or undermine the programs, including work requirements; policies that undermine the Health Insurance Marketplace or other markets forff health insurance; policies that make it more difficult assistance, including for dependents. This Executive Order also directs the U.S. Department of Health and Human Services to create a special enrollment period for the Health Insurance Marketplace in response to the COVID-19 pandemic. to enroll in Medicaid and the ACA; and policies that reduce affordabilit y of coverage or financial ff ff We expect that these healthcare reforms, as well as other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any approved product and/or the level of reimbursement physicians receive for administering any approved product we might bring to market. Reductions in reimbursement levels may negatively impact the prices we receive or the frequency with which our products are prescribed or administered. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from on anticipated revenue from private payors. Accordingly, such reforms, if enacted, could have an adverse effect product candidates that we may successfully develop and for which we may obtain marketing approval and may affect our overall financial condition and ability to develop or commercialize product candidates. ff ff The prices of prescripti considerab le legislativ dd products, if and when approve e avv pp ll d. ii on pharmaceuticals in the United States ctiontt nd executivtt e avv s and could impact the prices and foreign jurisdi rr tt ii we obtain for our drugrr ctions are subject to The prices of prescription pharmaceuticals have also been the subject b of considerable discussion in the United States. There have been several recent U.S. congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency to pharmaceutical pricing, review the relationship between pricing and manufacturer patient programs, and reduce the costs of In 2020, President Trump issued several executive orders pharmaceuticals under Medicare and Medicaid. intended to lower the costs of prescription products and certain provisions in these orders have been incorporated into regulations. These regulations include an interim final rule implementing a most favored nation model for prices that would tie Medicare Part B payments forff ive January 1, 2021. pharmaceuticals to the lowest price paid in other economically advanced countries, effect That rule, however, has been subject to a nationwide preliminary injunction and, on December 29, 2021, CMS issued a final rule to rescind it. With issuance of this rule, CMS stated that it will explore all options to incorporate value into payments forff Medicare Part B pharmaceuticals and improve beneficiaries' access to evidence-based care. certain physician-administered ff In addition, in October 2020, HHS and the FDA published a final rule allowing states and other entities to develop a Section 804 Importation Program, or SIP, to import certain prescription drugs from Canada into the United States. The final rule is currently the subject of ongoing litigation, but at least six states (Vermont , Colorado, Florida, Maine, New Mexico, and New Hampshire) have passed laws allowing forff drugs from Canada with the intent of developing SIPs for review and approval by the FDA. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed by the Biden administration until January 1, 2023. as well as a new safe harbor the importation of VV f 95 At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, health care organizations and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. In other countries, particularly the countries of the European Union, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a drug. To obtain reimbursement or pricing approval in some countries, we, or our collaborators, may be required to conduct a iveness of our drug to other available therapies. If reimbursement of clinical trial that compares the cost-effect our drugs is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be materially harmed. ff ff We are srr and other tt civilvv or crimin rr our busines ii ubject to anti-corruptiu on laws, as well all s export ee laws governing our operatiorr sww ns.

We may in the future operate in jurisdictions that pose a high risk of potential FCPA oPP relationships with third parties whose actions could potentially subject us to liability under the FCPA,PP the Bribery Act, or local anti-corruption laws.

There is no assurance that we will be completely effect ff ive in ensuring our compliance with all applicable anti-corruption laws, including the FCPA,PP the Bribery Act, or other legal requirements, including Trade Control Laws.

The loss of the services of our executive officeff could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers key employees may be diffiff cult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain marketing approval of and commercialize products. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may be employed by employers other than us and may have commitments under consulting or advisory contracts with other entities that may limit their availability to us.

In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations regulate a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Other forms of misconduct ion obtained in the course of clinical trials or creating fraudulent data could involve the improper use of informat in our preclinical studies or clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. We have adopted a code of conduct and implement other internal controls applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effeff ctive in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits ff 98 ff to comply with these laws or regulations. Additionally, we are subject to the risk that a stemming from a failure person could allege such fraud or other misconduct, even if none occurred. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect results of operations. our ability to operate our business and our ff Risks Related to Our Common Stock The price of our common stock is volatil of all or part of our stockholde rs’ invesvv kk ll tment. e and may fluctuate stt ubstantially,l which could result in the loss Our stock price is volatile. The stock market in general and the market for smaller biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. The market price for our common stock may be influenced by many factors, including: ff • • • • • • • • • • the degree of success of competitive products or technologies; results of or developments in preclinical studies and clinical trials, of our product candidates or those of our competitors; regulatory or legal developments in the United States and other countries; developments or disputes concerning patent applications, issued patents or other proprietary rights; the recruitment or departure of key personnel; the level of expenses related to any of our product candidates or clinical development programs; the results of our effoff product candidates; rts to discover, develop, acquire or in-license additional technologies or actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities analysts; variations in our financial results or those of companies that are perceived to be similar to us; changes in the structure of healthcare payment systems; • market conditions in the pharmaceutical and biotechnology sectors; • • general economic, industry and market conditions; and the other factors described in this “Risk Factors” section. If any of the foregoing matters were to occur, or if our operating results fall f below the expectations of investors or securities analysts, the price of our common stock could decline substantially. In the past, followin g periods of volatility in the market price of a company’s securities, securities class-action litigation often has been instituted against that company. Such litigation, if instituted against us, could cause us to incur substantial costs to defend such claims and divert management’s attention and resources, which could seriously harm our business, financial condition, results of operations and prospects. ff Our execu ee abilityll tive officers, directo ii rs and principal stockholders, if they choose to act together, have the .ll to significantly influence or control all matters submitted to stockholders for approval rr Our executive officers ff and directors, combined with our stockholders who own more than 5% of our outstanding common stock, in the aggregate, beneficially own shares representing approximately 27% of our capital stock. As a result, if these stockholders were to choose to act together, they would be able to significantly influence or control all matters submitted to our stockholders for approval, as well as our management and ff affai rs. For example, these persons, if they choose to act together, could significantly influence or control the 99 election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership control may: • • • delay, defer or prevent a change in control; entrench our management and the board of directors; or impede a merger, consolidation, takeover or other business combination involving us that other stockholders may desire. sioii Provi ns in our corpor rr company, which may be beneficialii rr rr o repla stockholders t aterr rr ce or remove our currerr nt management.tt charter documents, under Delaware l rr awll could make an acquisitio ii n of our to our stockhokk dd lders, more difficult and may prevent attempts by our Provisions in our certificate of incorporation and our bylaws may discourage, delay or prevent a merger, acquisition or other change in control of our company that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible forff appointing the members of our management team, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among other things, these provisions: ff • • • • • • • • provide for a classified board of directors such that only one of three classes of directors is elected each year; allow the authorized number of our directors to be changed only by resolution of our board of directors; limit the manner in which stockholders can remove directors from our board of directors; provide for advance notice requirements for stockholder proposals that can be acted on at stockholder meetings and nominations to our board of directors; require that stockholder actions must be effect actions by our stockholders by written consent; ff ed at a duly called stockholder meeting and prohibit limit who may call stockholder meetings; authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a “poison pill” that would work to dilute the stock ownership of a potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors; and require the approval of the holders of at least 75% of the votes that all our stockholders would be entitled to cast to amend or repeal specified provisions of our charter or bylaws. Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us forff transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner. a period of three years after the date of the An active tradi rr ngii market for our common stock may not be sustained.

ToTT achieve compliance with Section 404 within the prescribed period, we will be engaged in a process to document and evaluate our internal control over financial reporting, which is both costly and challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage outside consultants and adopt a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate, validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal control over financial reporting.

Our Busines ii s Overview We are a clinical-stage biopharmaceutical company dedicated to improving the lives of patients ng from debilitating and life-threatening diseases through the discovery, development and sufferi ff commercialization of therapies to degrade disease-causing proteins. We use our PROTAC Discovery Engine, proprietary technology platform to engineer proteolysis targeting chimeras, or PROTACTT degraders, that are designed to harness the body’s own natural protein disposal system to selectively remove disease-causing proteins. We believe that our targeted protein degradation approach is a therapeutic modality that may provide distinct advantages over existing modalities, including traditional small molecule therapies and technology has the potential to address a broad range of gene-based medicines. Our small-molecule PROTACTT intracellular disease targets, including those representing up to the 80% of proteins that currently cannot be targeted protein 105 addressed by existing small molecule therapies, commonly referred to as “undruggable” targets. We are using our PROTACTT target diseases in oncology (including immuno-oncology), neuroscience, and other therapeutic areas. Our three lead product candidates are bavdegalutamide, ARV-RR 471, and ARV-766. Discovery Engine to build an extensive pipeline of protein degradation product candidates to VV Bavdegalutamide We are developing bavdegalutamide, an investigational orally bioavailable PROTAC protein degrader targeting the androgen receptor protein, or AR, for the treatment of men with metastatic castration-resistant prostate cancer, or mCRPC. We initiated a Phase 1 clinical trial of bavdegalutamide designed to assess the safety, tolerability and pharmacokinetics of bavdegalutamide, which also includes measures of anti-tumor activity as secondary endpoints, including reduction in prostate specific antigen, or PSA, a well-recognized biomarker of prostate cancer progression. We received fast track designation for bavdegalutamide for mCRPC rth quarter of 2020, we in May 2019. We have completed dose escalation in the Phase 1 clinical trial. In the fouff initiated ARDENT, tTT he Phase 2 single agent expansion portion of the bavdegalutamide clinical trial. In the fouff rth quarter of 2021, we initiated a Phase 1b clinical trial with bavdegalutamide in combination with abiraterone for the treatment of men with mCRPC. In the first half of 2022, we intend to initiate discussions with the U.S. Food and Drug Administration, or FDA, about the potential for an accelerated approval pathway with bavdegalutamide in molecularly defined mCRPC and finalize a partnership for a companion diagnostic. In the second half of 2022, we plan to initiate a pivotal trial for patients with AR T878/H875 tumor mutations. We anticipate that future studies will be planned to explore the potential to treat earlier-line patients with AR-dependent tumors who may benefit from bavdegalutamide therapy. ARV-471 We are developing ARV-471, VV an investigational orally bioavailable PROTAC protein degrader targeting TT the treatment of patients with locally advanced or metastatic ER the estrogen receptor protein, or ER, forff positive / HER2 negative breast cancer. We initiated a Phase 1 clinical trial of ARV-RR 471 designed to assess the safety, tolerability and pharmacokinetics of ARV-RR 471, which also includes measures of anti-tumor activity as secondary endpoints. In the fouff rth quarter of 2020, we initiated a Phase 1b cohort expansion of ARV-RR 471 in combination with Ibrance® (palbociclib). We have completed dose escalation in the Phase 1 clinical trial. In the first quarter of 2021, we initiated VERITAC, the Phase 2 single agent expansion cohort of the ARV-RR 471 clinical trial. In July 2021, we entered into a collaboration agreement with Pfizer, pursuant to which we granted Pfizer worldwide coexclusive rights to develop and commercialize ARV-RR 471. In December 2021, we presented data from the dose escalation portion of the Phase 1/2 clinical trial at the San Antonio Breast Cancer Symposium. In the second dosed at 200 and 500 mg) and present safety data from the Phase 1b combination study with palbociclib. Additionally, in 2022, we plan to initiate a Phase 1b clinical trial with ARV-471 patients with metastatic breast cancer, initiate a Phase 1b combination trial with cyyclin-dependent kinase, or CCDK, inhibitors or other t gargeted therapies, initiate a Phase 2 clinical trial in patients with early breast cancer in the neoadjuvant setting and initiate Phase 3 clinical trials in patients with metastatic breast cancer as a monotherapy and in combination. fof 2022, we plan to present data from the VERITACTT Phase 2 dose expansion (with patients in combination with everolimus in fhalf VV ARV-766 We are developing ARV-766, VV an investigational orally bioavailable PROTACTT protein degrader for the treatment of men with mCRPC. In preclinical studies, ARV-RR 766 degraded all tested resistance-driving point mutations of AR, including L702H, a mutation associated with treatment with abiraterone and other AR-pathway therapies, which bavdegalutamide did not degrade in preclinical studies. In 2021, we initiated a Phase 1 clinical trial for ARV-RR 766 designed to assess the safety, tolerability and pharmacokinetics of ARV-RR 766, which also includes measures of anti-tumor activity as secondary endpoints, including reduction in PSA. In the second half of 2022, we plan to present Phase 1 dose escalation data and initiate a Phase 2 expansion trial for the treatment of men with mCRPC. Bavdegalutamide, ARV-RR 471 and ARV-RR 766 have all demonstrated potent and selective protein degradation in our preclinical studies. We believe favorable clinical trial results in these initial oncology programs would provide validation of our platform as a new therapeutic modality forff diseases caused by dysregulated intracellular proteins regardless of therapeutic area. the potential treatment of 106 OOur OOperations AAs a result off the COCOVID-19 pandemic, ymany companies have experienced disruptions in their y ymay take additional precaut employees' well-beingg and minimize business disruption.

Our operations to date have been limited to organizing and staffingff our company, business planning, raising capital, conducting discovery and research activities, filing patent applications, identifying potential product candidates, undertaking preclinical studies and clinical trials and establishing arrangements with third parties for the manufacture of initial quantities of our product candidates. To date, we have not generated any revenue from product sales and have financed our operations primarily through sales of our equity interests, proceeds from our collaborations, grant funding and debt financing. Through December 31, 2021, we raised approximately $1.3 billion in gross proceeds from the sale of equity instruments and the exercise of stock options, and had received an aggregate of $$774.0 million in payments primarily from collaboration partners. In July 2021, we entered into a collaboration agreement, or the ARV-RR 471 Collaboration Agreement, with Pfizer Inc., or Pfizer, pursuant to which we granted Pfizer worldwide co-exclusive rights to develop and commercialize products containing our proprietary compound ARV-RR 471, or the Licensed Products. Under the ARV-RR 471 Collaboration Agreement, we received an upfront, non-refundable payment of $650 million. In addition, we will be eligible to receive up to an additional $1.4 billion in contingent payments based on specific regulatory and sales-based milestones for the Licensed Products. Of the total contingent payments, $400 million in regulatory milestones are related to marketing approvals and $1.0 billion are related to sales-based milestones. We and Pfizer will share equally (50/50) all development costs, including costs forff conducting clinical trials, for the Licensed Products, subject to certain exceptions.

We and Pfizer will determine which, if any, regions within the world will be solely commercialized by one party, and in such region the parties will adjust their share of all profits and losses for the Licensed Products based on the role each party will be performing. ff In addition, in connection with the execution of the ARV-RR 471 Collaboration Agreement, in July 2021, we and Pfizer entered into a Stock Purchase Agreement, or Pfizer Stock Purchase Agreement, forff issuance of 3,457,815 shares of our common stock, or the Shares, to Pfizer at a price of $101.22 per share, for an aggregate purchase price of $350 million, or the Pfizer Equity Transaction, which was consummated in September 2021. We have determined that the fair market value of the Pfizer Equity Transaction totaled $264.6 million and allocated the $85.4 million excess purchase price to the ARV-471 Pursuant to terms of the Pfizer Stock Purchase Agreement, Pfizer has agreed not to sell or transfer the Shares without our prior written approval for a specified time period, subject to specified exceptions. Collaboration Agreement. the sale and VV We are a clinical-stage company. Bavdegalutamide and ARV-RR 471 are each in Phase 1/2 clinical trials, ARV-RR 766 is in a Phase 1 clinical trial, and our other drug discovery activities are at the research and preclinical development stages. Our ability to generate revenue from product sales sufficient depend heavily on the successful development and eventual commercialization of one or more of our product candidates. Since inception, we have incurred significant operating losses. We expect to continue to incur significant expenses and increasing operating losses for at least the next several years. Our net losses were $191.0 million, $119.3 million and $70.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021, we had an accumulated deficit of $$682.9 mill to achieve profitability will ion . ff 107 Our total operating expenses were $242.0 million, $146.7 million, and $94.5 million for the years ended December 31, 2021, 2020, and 2019, respectively. We anticipate that our expenses will increase substantially due to costs associated with our ongoing and anticipated clinical activities for bavdegalutamide, ARV-RR 471, and ARV-RR 766, development activities associated with our other product candidates, research activities in oncology, neurological and other disease areas to expand our pipeline, hiring additional personnel in research, clinical trials, quality and other functional areas, increased expenses incurred with CMOs to supply us with product for our preclinical and clinical studies and CROs forff activities, as well as other associated costs including the management of our intellectual property portfolio. the synthesis of compounds in our pre-clinical development We do not expect to generate revenue from sales of any product for many years, if ever. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research or product development programs or any future commercialization effort rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. s, or to relinquish valuable ff Revenue Financial Operations Overview To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the foreseeable future. Our revenues to date have been generated through research collaboration and license agreements. Revenue is recognized ratably over our expected performance period under each agreement. We expect that any revenue for the next several years will be derived primarily from our current collaboration agreements and any additional collaborations that we may enter into in the future. To date, we have not received any sales-based milestone payments or royalties under any of the collaboration agreements. ff Genentech License Agreement In September 2015, we entered into an Option and License Agreement with Genentech, Inc. and F. ff Roche Ltd, collectively referred to as Genentech, focused on PROTAC targeted protein degrader Hoffmann-La discovery and research for target proteins, or Targets, based on our proprietary platform technology, other than excluded Targets as described below.

For each identified Target, we and Pfizer will conduct a separate research program pursuant to a research plan. Pfizer may make substitutions for any of the initial Target candidates, subject to the stage of research for such Target. In the year ended December 31, 2018, we received an upfront, non-refundable payment and certain additional payments totaling $28.0 million in exchange for use of the technology license and to fund Pfizer- related research as defined within the Pfizer Research Collaboration Agreement. We are eligible to receive up to an additional $37.5 million in non-refundable option payments if Pfizer exercises its options for all targets under the Pfizer Research Collaboration Agreement.

Collaboration Agreement anywhere Operatingii Expense xx s Our operating expenses since inception have consisted solely of research and development costs and general and administrative costs. Research and Development ExpeEE nses Research and development expenses consist primarily of costs incurred for our research activities, including our discovery effort ff s, and the development of our product candidates, and include: • • • • • • salaries, benefits and other related costs, including stock-based compensation expense, for personnel engaged in research and development functions; expenses incurred under agreements with third parties, including contract research organizations and other third parties that conduct research and preclinical activities on our behalf as well as third parties that manufacture our product candidates for use in our preclinical studies and clinical trials; costs of outside consultants, including their fees, stock-based compensation and related travel expenses; the costs of laboratory supplies and developing preclinical studies and clinical trial materials; facility-related expenses, which include direct depreciation costs of equipment and allocated expenses for rent and maintenance of facilities and other operating costs; and third-party licensing fees. We expense research and development costs as incurred. 110 We typically use our employee and infrastructure resources across our development programs, and as such, do not track all of our internal research and development expenses on a program-by-program basis. The following table summarizes our research and development expenses for our AR program, which includes bavdegalutamide and ARV-RR 766, ER program, which includes ARV-RR 471, and all other platform and exploratory research and development costs: (dollars in millions) AR program development costs ER program development costs Other research and development costs Total research and development costs Years Ended December 31, 2021 2020 2019 $ $ 41.8 $ 24.4 $ 30.9 107.7 17.5 66.5 180.4 $ 108.4 $ 12.1 6.2 48.9 67.2 Research and development activities are central to our business model. We expect that our research and development expenses will continue to increase substantially for the foreseeable future as we conduct clinical trials for bavdegalutamide, ARV-RR 471 and ARV-RR 766, including our ongoing Phase 1/2 clinical trials for bavdegalutamide and ARV-RR 471 and our ongoing Phase 1 clinical trial for ARV-RR 766, and continue to discover and develop additional product candidates. Research and development expenses related to ARV-RR 471 are shared equally with Pfizer from July 22, 2021, the effective date of the ARV-RR 471 Collaboration Agreement. The ER program development costs in the table above reflect the cost sharing with Pfizer. ff We cannot reasonably estimate or determine with certainty the duration and costs of future clinical trials of bavdegalutamide, ARV-RR 471 and ARV-RR 766 or any other product candidate we may develop or if, when, or to what extent we will generate revenue from the commercialization and sale of any product candidate forff which we obtain marketing approval. We may never succeed in obtaining marketing approval for any product candidate. The successful development and commercialization of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of: • • • • • successful completion of preclinical studies; successful initiation of clinical trials; successful patient enrollment in and completion of clinical trials; receipt and related terms of marketing approvals from applicable regulatory authorities; obtaining and maintaining patent and trade secret protection and regulatory exclusivity forff product candidates; our • making arrangements with third-party manufactu f rers, or establishing manufacturing f capabilities, for both clinical and commercial supplies of our product candidates; • • • establishing sales, marketing and distribution capabilities and launching commercial sales of our products, if and when approved, whether alone or in collaboration with others; acceptance of our products, if and when approved, by patients, the medical community and third- party payors; obtaining and maintaining third-party coverage and adequate reimbursement; • maintaining a continued acceptable safety profile of the products followin ff g approval; and • effectively competing with other therapies. A change in the outcome of any of these variables with respect to the development of a product candidate could mean a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in our clinical trials due to patient enrollment or other reasons, we would be required to expend significant additional financial resources and time on the completion of clinical development. 111 General and Admidd nisii tratrr ivtt e Evv xpEE enses General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation for personnel in our executive, finance, business development and administrative functions.

The preparation of our consolidated financial statements and related disclosures requires us to make estimates and assumptions that affect liabilities, costs and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. 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 the reported amounts of assets and assumptions or conditions. ff ff While our significant accounting policies are described in more detail in the notes to our consolidated financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the followin accounting policies are those most critical to the judgments and estimates used in the preparation of our consolidated financial statements. ff g 112 Revenue Recognition We re gcognize revenue under Account ging SStandards C fCodification, or SASCC, 606, Revenue ffrom CContracrr tstt ustomers.rr Our revenue is generated through research collaboration and license agreements with wit Ch Ctt pharmaceutical partners. The terms of these agreements contain multiple goods and services which may include (i) licenses, (ii) research and development activities and (iii) participation in joint research and development steering committees. The terms of these agreements may include non-refundable upfront license research and development activities, payments upon the achievement of certain or option fees, payments forff milestones, and royalty payments based on product sales derived from the collaboration. Under ASC 606, we evaluate whether the license agreement, research and development services, and participation in research and obligations. We have development steering committees, represent separate or combined performance ff determined that these services within our existing contracts represent a combined single performance obligation. ff The research collaboration and license agreements typically include contingent milestone payments related to specified preclinical and clinical development milestones and regulatory milestones. These milestone payments represent variable consideration that are not initially recognized within the transaction price as they are fully constrained under the guidance in ASC 606. We will continue to assess the probability of significant reversals for any amounts that become likely to be realized prior to recognizing the variable consideration associated with these payments within the transaction price. Revenue is recognized ratably over our expected performance ff period under each respective arrangement. We make our best estimate of the period over which we expect to fulfill our performance obligations, which includes access to technology through the license agreement and research activities. Given the uncertainties of these collaboration arrangements, significant judgement is required to determine the duration of the performance period. ff For the years ended December 31, 2021, 2020 and 2019, the transaction price allocated to the ff obligation identified under the individual research collaboration and license agreements combined performance was recognized as revenue on either a straight-line basis over the estimated performance arrangement or over the estimated performance Straight-line basis was considered the best measure of progress for certain agreements in which control of the combined obligation transfers to the customers, due to the contract containing license rights to technology, research and development services, and joint committee participation, which in totality are expected to occur ratably over the performance period. period under the period based on our best estimate of costs to be incurred. ff ff Our contracts may also call for certain sales-based milestone and royalty payments upon successful commercialization of a target. In accordance with ASC 606-10-55-65, we recognize revenues from sales-based milestone and royalty payments at the later of (i) the occurrence of the subsequent sale, or (ii) the performance obligation to which some or all of the sales-based milestone or royalty payments has been allocated has been satisfied (or partially satisfied). We anticipate recognizing these milestone and royalty payments if and when subsequent sales are generated by the customer from the use of the technology. To dTT these sales-based milestone and royalty payments has been recognized for any periods. ate, no revenue from ff Amounts received prior to satisfying the above revenue recognition criteria are recorded as contract liabilities in our accompanying consolidated balance sheets. Research and Development Contract Costs and Accruals As part of the process of preparing our 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 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, require advance payments. We make estimates of our accrued expenses as of each balance sheet date in the financial statements based on facts and circumstances known to us at that time. We periodically confirm the on a pre-determined schedule or when contractual milestones are met; however, some on our behalf and ff ff ff 113 accuracy of these estimates with the service providers and make adjustments, if necessary. Examples of estimated accrued research and development expenses include fees paid to: • • vendors in connection with clinical development activities; and CROs and investigative sites in connection with pre-clinical, non-clinical, and human clinical trials ff We base the expense recorded related to external research and development on our estimates of the expended pursuant to quotes and contracts with multiple CMOs and CROs that services received and efforts supply, conduct and manage 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 streams. 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. In accruing service fees, we estimate the time period over which services will be performed the level of effort to be expended in each period. If the actual timing of the performance of effort ff Although we do not expect our estimates to be materially different ff relative to the actual status and timing of services understanding of the status and timing of services performed performed may vary and may result in reporting amounts that are too high or too low in any particular period.

To date, we have financed our operations primarily through the sale of equity interests and through payments from collaboration partners, grant funding, and loans from the State of Connecticut. Through December 31, 2021, we had received an aggregate of $774.0 million in payments from collaboration partners, grant funding and forgivable and partially forgivable loans from the State of Connecticut, and raised approximately $1.3 billion in gross proceeds from the sale of equity interests and the exercise of stock options, including: • October 2018: completion of our IPO, in which we issued and sold an aggregate of 7,700,482 shares of common stock for aggregate gross proceeds of $123.2 million beforeff fees and expenses; • July 2019: sale of 1,346,313 shares of common stock to Bayer AG for aggregate gross proceeds of $32.5 million; • November 2019: completion of a follow-on ff offering ff common stock for aggregate gross proceeds of $115.0 million beforeff in which we issued 5,227,273 shares of fees and expenses; • offering” ff September - December 2020: sale of 2,593,637 shares of common stock in an “at-the-market for aggregate gross proceeds of $65.6 million beforeff fees and expenses; • December 2020: completion of a follow-on ff offering ff in which we issued 6,571,428 shares of common stock for aggregate gross proceeds of $460.0 million beforeff fees and expenses; and • September 2021: issuance of 3,457,815 share of common stock to Pfizer for aggregate gross proceeds of $350 million. In May 2021, we entered into a lease for approximately 160,000 square feet of laboratory and officeff space to be occupied in 2024. In connection with the signing of the lease, and at our election to increase the landlord’s contribution to the tenant’s improvement allowance, we issued a letter of credit for $4.5 million, 115 collateralized by a certificate of deposit in the same amount. Once occupied, the base rent will range from $7.7 million to $8.8 million annually over a ten-year lease term. In July 2021, we entered into the ARV-471 Collaboration Agreement with Pfizer, pursuant to which we granted Pfizer worldwide co-exclusive rights to develop and commercialize the Licensed Products. Under the ARV-RR 471 Collaboration Agreement, Pfizer made an upfront, nonrefundable payment of $650 million.

We believe that our cash, cash equivalents, restricted cash and marketable securities as of December 31, 2021 will enable us to fund our planned operating expenses and capital expenditure requirements multiple additional years beyond 2024. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, including: • • • • • • • • • the progress, costs and results of our ongoing clinical trials for bavdegalutamide, ARV-RR 471 and ARV-RR 766 and any future clinical development of bavdegalutamide, ARV-RR 471 and ARV-RR 766; the scope, progress, costs and results of preclinical and clinical development for our other product candidates and development programs; the number of, and development requirements for, other product candidates that we pursue, including our other oncology and neurodegenerative research programs; the success of our collaborations with Pfizer, Genentech and Bayer; the costs, timing and outcome of regulatory review of our product candidates; the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; ff the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; and ff our ability to establish additional collaboration arrangements with other biotechnology or pharmaceutical companies on favorable terms, if at all, for the development or commercialization of our product candidates. As a result of these anticipated expenditures, we will need to obtain substantial additional financing in connection with our continuing operations. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our cash needs through a combination of equity offeff collaborations, strategic alliances and marketing, distribution or licensing arrangements. Although we may receive potential future payments under our collaborations with Pfizer, Genentech and Bayer, we do not currently have any committed external source of funds. Adequate additional funds may not be available to us on acceptable terms, or at all.

Borrowingii s In January 2014, we entered into an Assistance Agreement with the State of Connecticut, or the 2014 Assistance Agreement. Under the terms of the 2014 Assistance Agreement, we borrowed $2.5 million. Borrowings under the 2014 Assistance Agreement were forgivable if we maintained a minimum number of full- time jobs in the State of Connecticut for a minimum period at a minimum annual salary. Effective in March 2016, the full principal amount under the 2014 Assistance Agreement had been forff given. While borrowings under the 2014 Assistance Agreement have been forff given, we remain subject to an ongoing covenant to be located in the State of Connecticut through January 2024. Upon violation of this covenant, we would be required to repay the full original funding amount of $2.5 million plus liquidated damages of 7.50%. In June 2018, we entered into an additional Assistance Agreement with the State of Connecticut, or the 2018 Assistance Agreement, to provide funding for the expansion and renovation of laboratory and officeff space. Under the terms of the 2018 Assistance Agreement, we were entitled to borrow from the State of Connecticut a maximum of $2.0 million, provided that the funding did not exceed more than 50% of the total costs of the expansion and renovation. Borrowings under the 2018 Assistance Agreement bear an interest rate of 3.25% per annum and interest payments are required for the first 60 months from the funding date. Interest expense related to the 2018 Assistance Agreement is expected to be $0.1 million annually for the first five years. Thereafter , the loan begins to fully amortize through month 120, maturing in June 2028. The 2018 Assistance Agreement requires that we be located in the State of Connecticut through June 2028 with a default penalty of repayment of the full original funding amount of $2.0 million plus liquidated damages of 7.5% of the total amount of funding received. ff We borrowed the full $2.0 million under the 2018 Assistance Agreement in September 2018. Up to $1.0 million of the funding can be forgiven if we meet certain employment conditions, which were met in April 2021 and we were granted loan forgiveness of $1.0 million from the State of Connecticut. At December 31, 2021, $1.0 million remains outstanding under the 2018 Assistance Agreement. Item 7A. Quantitative and Qualitative Disclosures About Market Risk. We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. Our interest-earning assets consist of cash, cash equivalents, restricted cash and marketable securities. Interest income earned on these assets totaled $$1.9 million in 2021. O. ur interest income is sensitive to changes in the general level of interest rates, primarily U.S. interest rates. At December 31, 2021, our cash equivalents consisted of bank deposits and money market funds, and our marketable securities included interest-earning securities. Such interest-earning instruments carry a degree of interest rate risk. Our outstanding debt was $1.0 million as of December 31, 2021 and carries a fixed interest rate of 3.25% per annum. Item 8.

AND SUBSIDIARIES Notes to Consolidated Financial Statements 1. Nature of Business and Basis of Presen rr tation Nature of Business Arvinas, Inc. is a clinical-stage biopharmaceutical company dedicated to improving the lives of patients ng from debilitating and life-threatening diseases throughout the discovery, development and sufferi ff commercialization of therapies to degrade disease-causing proteins. Arvinas, Inc. has four subsidiaries; Arvinas Operations, Inc. formed in 2013, Arvinas Androgen Receptor, Inc. formed in 2015, Arvinas Estrogen Receptor, Inc. formed in 2016, and Arvinas Winchester, Inc. formed in 2018 (collectively, the "Company"). wholly owned ff Basis of Presentati tt on The Company's consolidated financial statements are prepared in conformit y with accounting principles generally accepted in the United States of America ("U.S. GAAP") and include the accounts of Arvinas, Inc. and its wholly owned subsidiaries. All intercompany transactions have been eliminated upon consolidation. The accounting policies used to prepare the Company's consolidated financial statements are the same as those used to prepare the consolidated financial statements in prior years, except for the adoption of new standards as outlined below. ff The preparation of the Company’s consolidated financial statements in conformit ff y with U.S. GAAPAA requires management to make certain estimates and assumptions that affect the reported amounts and disclosures in the financial statements and notes. While management believes that estimates and assumptions used in the preparation of the consolidated financial statements and notes are appropriate, actual results could differ ff Company’s revenue recognition, research and development expenses, and fair venture, Oerth Bio LLC ("Oerth"). from those estimates. The most significant estimates are those used in the determination of the value of its investment in a joint ff Concentrati tt on of Credit Risk and Other tt Risks and Uncertaint tt iestt The Company is subject to a number of risks similar to other biopharmaceutical companies in the early stage, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, the need to obtain marketing approval for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s products, and protection of proprietary technology. If the Company does not successfully obtain regulatory approval, it will be unable to generate revenue from product sales or achieve profitability. To date, the Company has not generated any revenue from product sales and has financed its operations primarily through sales of equity interests, proceeds from collaborations, grant funding and debt financing. Through December 31, 2021, the Company raised approximately $1.3 billion in gross proceeds from the sale of equity instruments and the exercise of stock options, and had received an aggregate of $774.0 million in payments primarily from collaboration partners. The Company had cash, cash equivalents, restricted cash and marketable securities of approximately $1.5 billion as of December 31, 2021. 2. Summary of Significant Accounting Polici ll es Cash and Cash Equivalents The Company classifies as cash and cash equivalents amounts on deposit in banks and cash invested temporarily in various instruments, primarily money market accounts, with original maturities of three months or less at time of purchase. The carrying amounts reported in the consolidated balance sheets represent the fair values of cash and cash equivalents. F-9 Restricted Cash Restricted cash represents a letter of credit collateralized by a certificate of deposit in the same amount as required under the terms of the Company's laboratory and offiff ce space lease entered into in May 2021. Concentration of Creditdd Risk The Company maintains its cash in financial institution accounts that may at times exceed federally insured limits. The cash balances in the financial institutions are insured by the Federal Deposit Insurance Corporation ("FDIC") up to $250,000. Cash may also be maintained at commercial institutions that are not insured by the FDIC. For the years ended December 31, 2021 and 2020, 100% of the Company’s revenue was attributable to three collaborators representing 68%, 17% and 15% in 2021, and 37%, 32% and 31% in 2020. For each of the years ended December 31, 2021 and 2020, one collaborator accounted for the entire accounts receivable balance. For the year ended December 31, 2019, 57% of the Company’s revenue was attributable to a license contributed to Oerth, and two collaborators represented 19% and 16% of total revenue. Marketable Securities The Company's marketable securities are classified as available-for-sale securities and are carried at their fair value based on the quoted market prices of the securities, with unrealized gains and losses reported as accumulated other comprehensive income (loss), a separate component of stockholders' equity. Realized gains and losses on available-for-sale securities are included in other income in the period earned or incurred. Proprr erty, Equipmii ent, and Leasehold ImpII rovements Property and equipment are recorded at cost. Depreciation is calculated using the straight-line method over the estimated useful lives, which range from three years for officeff equipment. Maintenance and repairs which do not extend the lives of the assets are charged directly to expense as incurred. Upon retirement or disposal, cost and related accumulated depreciation are removed from the related accounts, and any resulting gain or loss is recognized as a component of income or loss for the period. Leasehold improvements are recorded at cost and amortized using the straight-line method over the shorter of the lease term or the useful life of the asset. equipment to five years for laboratory rr Impairmen t of Long-Lived Assets The Company evaluates the carrying value of long-lived assets when indications of potential impairments are present. The Company adjusts the carrying value of the long-lived assets if the sum of undiscounted expected future cash flows is less than the carrying value. No such impairments were recorded during 2021, 2020 or 2019. Segment Information ff Operating segments are defined as components of an enterprise about which separate discrete ion is available forff informat allocating resources. The Company, through its Chief Executive Officer maker, views Company operations and manages the business as one operating segment. All of the Company’s tangible assets are held in the United States and all of the Company’s revenue has been generated in the United States. evaluation by the chief operating decision maker in assessing performance in his role as chief operating decision and ff ff Revenue Recognition and Deferred Revenue Revenues from Contracts The Company recognizes revenue under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers. The Company’s revenue is generated through research collaboration and license agreements with pharmaceutical partners. The terms of these agreements contain multiple goods and services which may include (i) licenses, (ii) research and development activities, and (iii) participation in joint F-10 research and development steering committees. The terms of these agreements may include non-refundable, upfront license or option fees, payments forff achievement of certain milestones, and royalty payments based on product sales derived from the collaboration. Under ASC 606, the Company evaluates whether the license agreement, research and development services, and participation in research and development steering committees, represent separate or combined performance represent a combined single performance obligations. The Company has determined that these services within its existing contracts research and development activities, payments upon the obligation. ff ff The research collaboration and license agreements typically include contingent milestone payments related to specified preclinical and clinical development milestones and regulatory milestones. These milestone payments represent variable consideration to be included within the transaction price using the most likely amount method. The Company determined that the most likely amount to be recognized was zero, against which no constraint was applied. The Company will continue to assess the probability of significant reversals for any amounts that become likely to be realized prior to recognizing the variable consideration associated with these payments within the transaction price. Revenue is recognized ratably over the Company’s expected performance ff period under each respective arrangement. The Company makes its best estimate of the period over which the Company expects to fulfill the Company’s perforff mance obligations, which includes access to technology through the license agreement and research activities. Given the uncertainties of these collaboration arrangements, significant judgment is required to determine the duration of the performance period. For the years ended December 31, 2021, 2020 and 2019, the transaction price allocated to the ff obligation identified under the individual research collaboration and license agreements combined performance was recognized as revenue on either a straight-line basis over the estimated performance arrangement or over the estimated performance incurred. Straight-line basis was considered the best measure of progress for certain agreements in which control of the combined obligation transfers to the customers, due to the contract containing license rights to technology, research and development services, and joint committee participation, which in totality are expected to occur ratably over the performance period. period based on the Company’s best estimate of costs to be period under the ff ff The Company’s contracts may also call for certain sales-based milestone and royalty payments upon successful commercialization of a target. The Company recognizes revenues from sales-based milestone and royalty payments at the later of a) the occurrence of the subsequent sale, or b) the performance obligation to which some or all of the sales-based milestone or royalty payments has been allocated has been satisfied (or partially satisfied). The Company anticipates recognizing these milestones and royalty payments if and when subsequent sales are generated by the customer from the use of the technology. To dTT these sales-based milestone and royalty payments has been recognized for any periods. ate, no revenue from Amounts received prior to satisfying the above revenue recognition criteria are recorded as contract liabilities in the Company’s accompanying consolidated balance sheets. The Company expenses direct and incremental costs to obtaining and fulfilling a contract as and when incurred if the expected amortization period of the asset that would be recognized is one year or less, or if the amount of the asset is immaterial. Otherwise, such costs are capitalized as collaboration contract assets and amortized as general and administrative expenses over the total estimated period of performance of each underlying contract. The Company also recognized revenue under ASC 606 from its contribution of a license to Oerth in 2019. See Note 10. Equity Method Investments The Company accounts forff investments forff which it does not have a controlling interest in accordance with ASC 323, Investments –tt ethod and Joint Ventures. The Company recognizes its pro-rata share of income and losses in the investment in “Loss from equity method investment” on the consolidated statement of operations and comprehensive loss, with a corresponding change to the investment in equity method investment on the consolidated balance sheet until such investment is reduced to zero.

Estimated forfeitures are updated on a periodic basis based on actual experience. For equity awards that have a perforr of the probability that the performance condition will be achieved. rmance condition, the Company recognizes compensation expense based on its assessment The Company classifies equity-based compensation expense in its consolidated statement of operations in the same manner in which the award recipient’s salary and related costs are classified or in which the award recipient’s service payments are classified. Research and Development ExpeEE nses Research and development expenses include (i) employee-related expenses, including salaries, benefits, travel, and stock-based compensation expense; (ii) external research and development expenses incurred under arrangements with third parties, such as contract research organization agreements, investigational sites, and consultants; (iii) the cost of acquiring, developing, and manufacturing clinical study materials; (iv) costs associated with preclinical and clinical activities and regulatory operations; and (v) costs incurred in development of intellectual property. Costs incurred in connection with research and development activities are expensed as incurred. The Company enters into consulting, research, and other agreements with commercial entities, researchers, universities, and others for the provision of goods and services. Such arrangements are generally cancellable upon reasonable notice and payment of costs incurred. Costs are considered incurred based on an evaluation of the progress to completion of specific tasks under each contract using informat provided by the respective vendors, including the Company’s clinical sites. These costs consist of direct and indirect costs associated with specific projects, as well as fees paid to various entities that performff certain research on behalf of the Company. Depending upon the timing of payments to the service providers, the Company recognizes prepaid expenses or accrued expenses related to these costs. These accrued or prepaid expenses are based on management’s estimates of the work perforr rmed under service agreements, milestones achieved, and experience with similar contracts. The Company monitors each of these factors and adjusts estimates accordingly. ion and data ff Fair Vii aluVV e Measurements ASC Topic 820, Fair Value Measurements att nd Disclosures, requires disclosure of the fair value of Instrumentstt , defines fair value and establishes a ii financial instruments held by the Company. ASC 825, Financial three-level valuation hierarchy for disclosures of fair value measurement that enhances disclosure requirements for fair value measures. The three levels of valuation hierarchy are defined as follows: Level 1— Inputs are based upon observable or quoted prices (unadjusted) for identical instruments traded in active markets. F-12 Level 2— Inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. The Company’s Level 2 investments consist primarily of corporate notes and bonds and U.S. government and agency securities. rr Level 3— Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as considers counterparty credit risk in its assessment of fair value. The Company’s marketable securities consist of corporate bonds and government securities which are adjusted to fair value at each balance sheet date, based on quoted prices, which are considered Level 2 inputs. During the year ended December 31, 2021, a non-recurring fair value measurement was applied to determine the fair value of the 3,457,815 shares of the Company’s common stock (the "Shares") issued and sold to Pfizer, Inc. ("Pfizer") under the Stock Purchase Agreement entered into between the Company and Pfizer in July 2021 (the “Pfizer Stock Purchase Agreement”) at a price of $101.22 per share, for an aggregate purchase price of up to $350.0 million (the “Pfizer Equity Transaction”), which was consummated in September 2021. The fair value was determined by applying the discount due to lack of marketability during the contractual lock-up period to the public trad ging price fof the common stock, which is a Level 1 input, on the date fof sale. The Company Company accounted ffor the lack off marketabilityy duri gng the contractual lock-up period, yby uti considered Level 3 inputs S.

Diluted net loss per share is computed using the weighted- average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common shares. New Accounting ProPP nouncements Recentlytt Adopted Accountingtt Pronouncements ff Effeff ctive January 1, 2021, the Company adopted ASU 2019-12, Income Taxes (Topic 740): Simplif ying ii for Income Taxes, (“ASU 2019-12”) which simplifies the accounting for income taxes by the Accountingtt removing certain exceptions to the general principles in ASC 740 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 requires, among other requirements, the Company to recognize as an income tax the effect of state hybrid taxes that are based on the greater of an income-based tax and a capital-based tax. Adoption of ASU 2019-12 did not have a material impact on the Company’s financial statements since the Company has no state income tax liabilities due to its net operating losses. Additionally, the Company has not recorded any income tax benefits from these losses due to uncertainty of realizing the related tax benefit. 3.
