Business Overview PART I We are a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies for people with debilitating neurological and neuropsychiatric diseases, including rare disorders. Our experienced management team brings with it a track record of delivering new drug approvals for products for diseases such as migraine, depression, bipolar and schizophrenia. We are advancing a pipeline of therapies for diseases with little or no treatment options, leveraging our proven drug development capabilities and proprietary platforms, including Kv7 ion channel modulation for epilepsy and neuronal hyperexcitability, glutamate modulation for Obsessive-Compulsive Disorder (“OCD”) and Spinocerebellar Ataxia ("SCA"), myostatin inhibition for neuromuscular diseases, and brain-penetrant Tyrosine Kinase 2/Janus Kinase 1 ("TYK2/JAK1") inhibition for immune-mediated brain disorders. Our portfolio of early- and late-stage product candidates also includes discovery research programs focused on TRPM3 channel activation for neuropathic pain, CD-38 antibody recruiting, bispecific molecules for multiple myeloma, antibody drug conjugates ("ADCs"), and extracellular target degrader platform technology ("MoDE") with potential application in neurological disorders, cancer, and autoimmune diseases. We are advancing our broad and diverse pipeline, across early and late stage development, including three Phase 3 clinical programs. We have built a highly experienced team of senior leaders and neuroscience drug developers who combine a nimble, results-driven biotech mindset with capabilities in drug discovery and development. In addition, we have several preclinical assets in our early discovery program, targeting indications in neuroscience and immunology. Separation from Biohaven Pharmaceutical Holding Company Ltd. On May 9, 2022, the Board of Directors of Biohaven Pharmaceutical Holding Company Ltd. (the “Former Parent”) approved and directed Former Parent’s management to effect the spin-off of the Kv7 ion channel activators, glutamate modulation and myostatin inhibition platforms, preclinical product candidates, and certain corporate infrastructure then owned by Former Parent, or collectively the “Biohaven Business”. On October 3, 2022, the Former Parent completed the distribution (the “Distribution”) to holders of its common shares of all of the outstanding common shares of Biohaven Ltd. and the spin-off of Biohaven Ltd. from the Former Parent (the “Spin-Off”) described in Biohaven’s Information Statement attached as Exhibit 99.1 to Biohaven’s Registration Statement on Form 10, as amended (Reg. No. 001-41477), which was declared effective by the Securities and Exchange Commission ("SEC") on September 22, 2022 (the “Form 10”). Each holder of Former Parent common shares received one common share of Biohaven for every two of the Former Parent common shares held of record as of the close of business on September 26, 2022. To implement the Spin-Off, the Former Parent transferred the related license agreements, intellectual property and the Former Parent’s corporate infrastructure, including certain non-commercial employee agreements, share-based awards and other corporate agreements to Biohaven Ltd. Collectively, we refer to the Distribution and Spin-Off throughout this Annual Report on Form 10-K as the "Separation." As a result of the Separation, Biohaven Ltd. is an independent, publicly traded company, effective as of October 3, 2022, and commenced regular way trading under the symbol “BHVN”’ on the New York Stock Exchange ("NYSE") on October 4, 2022. Where we describe historical business activities in this report, we do so as if Former Parent’s activities related to such assets and liabilities had been performed by the Company. 1 Table of Contents Product Candidates The following table summarizes some of our key clinical programs in addition to upcoming clinical development milestones for our product candidates. We hold the worldwide rights to all of our product candidates. Kv7 Kv7 Platform Acquisition In February 2022, we announced that we entered into a definitive agreement with Channel Biosciences, LLC, a subsidiary of Knopp Biosciences, LLC, to acquire a drug discovery platform targeting Kv7 ion channels, adding the latest advances in ion channel modulation to our growing neuroscience portfolio. BHV-7000 (formerly known as KB-3061), the lead asset from the Kv7 platform is an activator of Kv7.2/Kv7.3, a key ion channel involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy. In the second quarter of 2022, our Clinical Trial Application for BHV-7000 was approved by Health Canada, and we subsequently began phase 1 clinical development, including a SAD/MAD study. The Company is evaluating and has not yet finalized potential future clinical trial designs, including trial size, and primary and secondary endpoints and expects to initiate an EEG study in the first half of 2023 and expects to initiate phase 2/3 studies in focal epilepsy patients and bipolar disorder patients in the second half of 2023. Kv7’s Role in Epilepsy and Other Central Nervous System Disorders Epilepsy Because of their fundamental role in health and their aberrant role in disease, ion channels in cell membranes represent a broad and important class of drug targets. Sodium channels and potassium channels form the ionic basis of the action potential in electrically charged cells throughout the body (see figures below). The Kv7 protein in particular forms a channel that exquisitely regulates the flow of charged potassium ions (K+) across cell membranes, repolarizing nerve cells and resetting them for normal action potential firing. Kv7 channels include a family of channel subtypes, designated as Kv7.1 through Kv7.5, and they are formed by tetramers of identical or compatible subunits. Some of these channel subtypes localize in nerve cells (neurons) while others can be found in cardiac muscle, smooth muscle, and other tissue types. The Kv7 subunits, Kv7.2 and Kv7.3, are widely expressed in the brain, notably in the cortex and hippocampus, and together they form Kv7.2/7.3 heteromeric channels that produce the M-current (I perform a natural “braking” function by regulating the electrical excitability and hyperexcitability of brain cells. Dysfunction of these channels, due to genetic mutations or other factors, increases seizure risk, while augmenting the ‘open’ activity of these channels has been demonstrated to reduce ), a critical regulator of neuronal excitability (see figures below). Kv7.2/7.3 channels normally KM 2 Table of Contents neuronal hyperexcitability and seizure frequency in electrophysiology laboratories, in animal models, and, most importantly, in patients. White, Role of Potassium Channel Ions in Epilepsy, Medscape.org We are synthesizing novel Kv7.2/7.3 activators that improve on the selectivity, potency, and other characteristics of ezogabine (Potiga in the U.S. and Trobalt (retigabine) in Europe), a drug approved in 2011 for the treatment of refractory epilepsy and voluntarily withdrawn from the market in 2017 because of poor tolerability and structure-related toxicities that limited its use, and ezogabine-like compounds while averting its negative attributes, including off-target activity at a different brain ion channel, gamma-aminobutyric acid (“GABA”) A receptor (“GABA -R”). A Using a structure-based approach, supplemented by in silico modeling, we have identified structural features of our molecules critical to Kv7 activation. We have applied these analyses to the generation of proprietary chemical leads structurally distinct from known Kv7 activators, including ezogabine and flupirtine, the only other approved Kv7 modulator, approved in Europe for the treatment of acute pain. Our team has synthesized a large library of Kv7-activating molecules and are advancing them according to stringent criteria requiring improvements over ezogabine, including chemical stability, synthetic tractability, the avoidance of structural motifs associated with the generation of reactive metabolites and other unwanted, off-target activity, including GABA -R activation. A Epilepsy is the initial disease we are targeting with activators from our Kv7 platform. Epilepsy affects approximately 3.5 million Americans, or more than 1.2% of adults and 0.6% of children in the U.S., and more than 50 million patients worldwide, according to the World Health Organization (“WHO”). It is the fourth most common neurological disorder, and many patients struggle to achieve freedom from seizures, with more than one third of patients requiring two or more medications to manage their epilepsy. While the use of anti-seizure medications is often accompanied by dose-limiting side effects, our clinical candidate BHV-7000 is specifically designed to target subtypes of Kv7 potassium channels without engagement of GABA receptors. The lack of GABA -R activity potentially gives BHV-7000 a wide therapeutic window and is expected to result in an improved side effect profile, limiting the somnolence and fatigue often seen in patients receiving anti-seizure medications. This preclinical profile is supported by preliminary safety data from our Phase 1 SAD/MAD trial of BHV-7000 in healthy volunteers, which showed a favorable CNS tolerability profile. By adding BHV-7000 to our pipeline, we aim to bring this potassium channel modulator as a potential solution to patients with epilepsy who remain uncontrolled on their current regimens. A A BHV-7000 is a Kv7.2/7.3 channel activator from a novel, bicyclic imidazole class with significant in vivo anticonvulsant activity and a wide therapeutic index. In the most widely used and positively-predictive preclinical model of epilepsy, the maximal electroshock (“MES”) model, data for BHV- 7000 and ezogabine were collected in independent experiments (see figures below), measuring the activity of both compounds in preventing seizures (ED50) and recording the neurologic deficit five minutes prior to the MES test to calculate the tolerability index (“TI”). The neurologic deficit is a behavioral index ranging from normal activity (score of 0) to a loss of righting reflex (score of 3). As shown below, BHV-7000 was demonstrated to have an ED50 = 0.5 mg/kg with almost no impact on behavior producing a TI > 40x. In contrast, ezogabine was 40x less potent (ED50 = 20 mg/kg) in the MES model with a narrow TI < 3x. The narrow preclinical TI for ezogabine is consistent with the clinical experience with the drug where side effects such as somnolence and dizziness limited its use at doses that prevented seizures in patients. 3 Table of Contents KCNQ2 Epileptic Encephalopathy KCNQ2 epileptic encephalopathy (“KCNQ2-EE”) is a rare pediatric epileptic encephalopathy first described in 2012 resulting from dominant- negative mutations in the KCNQ2 gene. Epileptic encephalopathies (“EE”) comprise a group of epilepsy syndromes in which onset of recurrent and medically refractory seizures are associated with cognitive and broader developmental delay or regression. Early infantile epileptic encephalopathy, also called Ohtahara syndrome, and early myoclonic encephalopathy are the earliest-presenting of these age-dependent syndromes, clinically defined by onset within the first three months after birth. Although only recently described, heterozygous de novo variants in KCNQ2 are a highly validated cause of early onset epileptic encephalopathy, and KCNQ2-EE has emerged as a well-defined clinical entity with a characteristic neonatal presentation, including hypotonia, treatment-resistant tonic seizures, a profoundly abnormal interictal electroencephalogram (“EEG”) with prominent burst-suppression, and most often with moderate-to-profound global developmental delay, resulting from a defined subset of missense variants in the gene. KCNQ2-EE is thus both a seizure disorder and a developmental disorder caused by pathogenic, dominant-negative KCNQ2 mutations. Identification of genetic etiologies has created the opportunity to treat not just the symptoms of KCNQ2-EE, including seizures, but also the underlying causes, including attenuating or reversing the effects of the dominant-negative variants responsible for KCNQ2-EE. Developmental delay is an intractable feature of KCNQ2-EE even though seizure frequency tends to diminish after infancy and EEG organization tends to improve. Importantly, limited clinical evidence, including a case series of four infants with KCNQ2-EE, suggests that pharmacological augmentation of reduced Kv7.2 channel current with ezogabine reduces seizures and may improve developmental milestone attainment. Severe pathogenic KCNQ2 mutations disrupt the function of the KCNQ2 gene product, Kv7.2, a voltage-gated potassium channel subunit which, in addition to being a critical regulator of neuronal excitability, plays a fundamental role in early brain development. Kv7.2 polypeptides are co-assembled in either homotetrameric channels, or, in combination with Kv7.3 subunits, to form heterotetrameric channels. Both subunit configurations contribute to IKM. Significant reduction of Kv7.2/7.2 activity or Kv7.2/7.3 activity with loss of 50% of more of current density through these channels abrogate these functions, leading to neuronal hyperexcitability and impaired brain development. In addition to its activity in the MES model, we explored the ability of BHV-7000 to reverse the reduced current density associated with KCNQ2-EE and support its use as potential treatment for the disease. Most encephalopathy-associated pathogenic KCNQ2 variants identified to date disrupt channel function in any of four distinct “hot spots” of the protein, including the S4 voltage sensor, the ion channel pore, and the proximal and distal regions of the C-terminal domain (see figure below). 4 Table of Contents Millichap, Neurol Genet (2016) To determine the effects of BHV-7000 on the function of Kv7.2 and Kv7.2/7.3 channels poisoned by dominant-negative KCNQ2 mutations, four highly recurrent human missense variants representative of the “hot spot” domains were introduced into KCNQ2 cDNA by site-directed mutagenesis. Using lipid-mediated transfection, plasmids including the pathogenic variants were co-expressed with wild-type (“wt”) KCNQ2 subunits or wt KCNQ2 and wt KCNQ3 subunits in Chinese hamster ovary cells. The figure below shows the effects of BHV-7000 on current density of wt/wt Kv7.2 channels and those formed by 1:1 coexpression of wt KCNQ2 genes with either of two KCNQ2 pore domain variants (T274M, A294V), a C-terminal variant (R581L), or a voltage-sensing variant (R210H). In the control condition, all pathogenic variants produced a marked reduction in current density to below wt/wt levels. BHV-7000 at 0.3µM restored current density in mutated pore and C-terminal channels to or beyond wt control current density (**<0.01). Similarly, application of BHV-7000 at 1 µM restores function to mutated channels expressing the R210H KCNQ2 S4 voltage sensor domain pathogenic variant in the heterotetrameric (wt/R210H) configuration, to above wt/wt levels of activation. BHV-7000 has been granted Rare Pediatric Disease Designation by the U.S. Food and Drug Administration ("FDA") for the treatment of KCNQ2- EE. Neuropathic Pain Neuropathic pain, as defined by the International Association for the Study of Pain, is pain caused by a lesion or disease of the somatosensory nervous system and includes a collection of heterogeneous conditions that are often chronic and debilitating and for which long term therapy is difficult. In the United States, over 30 million adults are estimated to be living with neuropathic pain. Pharmacological treatments for neuropathic pain vary according to patient needs, although recommendations such as the WHO analgesic ladder, United States Centers for Disease Control (“CDC”), and FDA guidelines are in use. Initial or first line treatment for neuropathic pain includes non-opioid analgesics, in particular, antidepressants, anticonvulsants, steroids, and anxiolytics. Second line treatment of persistent, severe pain 5 Table of Contents may require escalation to opiates, often less potent ones at first, followed by more potent opiates for intense refractory pain. Thus, an urgent need exists for effective, non-addictive pain therapies. Flupirtine, a non-selective Kv7 activator, was previously approved in several European countries and indicated for the treatment of pain. However, the European Medicines Agency recommended withdrawal of its marketing authorization in 2018 because of the risk of serious liver injury. Selective Kv7 potassium channel activators represent a new approach in the development of non-opioid therapeutic options for neuropathic pain. In addition to leveraging reduced abuse and addiction risk potential of potassium channel activators, our Kv7 potassium channel platform addresses the complexities of channel subtype physiology through targeted pharmacology to overcome the limitations inherent in unbiased Kv7 activators and is intended to deliver a well-tolerated, highly effective, non-opioid treatment for neuropathic pain. Our Kv7 program research was supported in part with funding from the National Institutes of Health (“NIH”) to advance the development of novel Kv7 non-opioid therapies for the treatment of chronic pain. The NIH funding is by the NIH Helping to End Addiction Long-term Initiative (“NIH HEAL Initiative”), which aims to improve treatments for chronic pain, curb the rates of opioid use disorder and overdose, and achieve long-term recovery from opioid addiction.The goal of our Kv7 program is to discover a small-molecule activator of the Kv7.2/7.3 voltage-gated potassium channel to treat neuropathic pain. Similar to our epilepsy program, we are targeting compounds with these characteristics: • Biased for Kv7.2/3 activation vs. Kv7.4 activation to minimize potential adverse smooth muscle effects • Selective against GABA receptors to minimize potential tolerability issues A • Selective against Kv7.1/KCNE1 (IKs) and hERG (IKr) to minimize cardiac side-effects • Potent and effective across animal models of neuropathic pain A fundamental program hypothesis is that creating Kv7.2/3 activators with minimal activation of Kv7.4 and GABA receptors will greatly improve the A tolerability profile of a successful candidate compound. Ezogabine has known effects on the GABA system, both directly as a GABA positive allosteric modulator, and indirectly by affecting GABA synthesis or metabolism, a pharmacology consistent with the dose-related increases in somnolence and dizziness reported in ezogabine clinical trials. Our program is directed to reducing this potential source of poor tolerability by selecting compounds with no or minimal activity for the GABA receptor. A A Axonal excitability and neurotransmitter release are altered in neuropathic pain due to sodium channel plasticity, increased voltage-gated calcium channels in the spinal cord, and diminished potassium channel activity in dorsal root ganglion (“DRG”) neurons. These changes in ion channel number, distribution, and function are common to many neuropathic pain subtypes. The functional density of Kv7.2/3 channels is a key variable governing sensory DRG control of intrinsic excitability. There are some reports that demonstrate downregulation of Kv7 potassium channel mRNA, protein and function in experimental neuropathic pain models. Using human induced pluripotent stem cell (“iPSC”)-derived DRG sensory neurons, we have assessed the physiological activity of these neurons by modulating Kv7 channels across three electrophysiologic parameters: resting membrane potential (Vm), rheobase = the current required to stimulate an action potential (“AP”), and the number of APs elicited by a suprathreshold stimulus (3x rheobase). We are currently evaluating the activity of various compounds from our proprietary series of selective Kv7.2/7.3 activators in multiple preclinical models of neuropathic pain. Mood disorders Approximately 1 in 5 adults in the U.S. are living with neuropsychiatric illnesses that are, in turn, associated with inadequate treatment, poor quality of life, disability, and considerable direct and indirect costs. There is significant unmet need for novel and effective therapeutic options that are not limited by long latency periods to clinical effects, low response rates, and significant risks and side effects. Increasing evidence from animal models and clinical trials now suggests that Kv7.2/7.3 targeting drugs offer the potential to treat a spectrum of these neuropsychiatric diseases including, but not limited to, mood disorders such as major depressive disorder, bipolar disorder and anxiety. Bipolar disorder is the initial mood disorder that we intend to target with activators from our Kv7 platform. Bipolar disorder affects approximately 7- 11 million Americans, with an estimated 4.4% of US adults having bipolar disorder over their lifetime. Bipolar disorder is associated with significant morbidity, decreased quality of life and economic burden. Treatment guidelines recommend patients receive life-long treatment for bipolar disorder. However, medication adherence is typically very low in this population, due in large part to undesirable side effects that are poorly tolerated by patients. The mainstays of treatment include mood stabilizing agents that are also used as anti-seizure medicines (i.e., valproic acid, lamotrigine, and topiramate). Preclinical and pilot clinical data similarly suggest a potential therapeutic role for Kv7 activation in bipolar disorder, which is expected to result in an improved side effect profile compared to other anti- 6 Table of Contents seizure medications. We plan to advance BHV-7000 as a potential treatment for patients with bipolar disorder and intend to start a clinical trial targeting this indication by the end of 2023. BHV-7010 BHV-7010 is being developed as a next generation Kv7.2/7.3 activator with improved selectivity over Kv7.4 and differentiated absorption, distribution, metabolism, and excretion ("ADME") properties that provide flexibility for the treatment of different neurological diseases. The IND is expected to be submitted in the second half of 2023. TYK2/JAK1 Agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd. In March 2023, we entered into an exclusive, worldwide (excluding People’s Republic of China and its territories and possessions) license agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd. ("Highlightll") (the "Highlightll Agreement"), whereby we obtained the right to research, develop, manufacture and commercialize Highlightll’s brain penetrant dual TYK2/JAK1 inhibitor program. Refer to 15, "Subsequent Events," of the Notes to the Consolidated Financial Statements appearing elsewhere in this Annual Report on Form 10-K for further discussion of the Highlightll Agreement. BHV-8000 Dysregulation of the immune system has been implicated in several neurodegenerative and neuroinflammatory disorders including Parkinson's Disease, Multiple Sclerosis, Alzheimer's Disease, Amyotrophic Lateral Sclerosis and Autoimmune Encephalitis. Over-active immune cells and microglia driving chronic neuroinflammation results in release of cytokines with activation of leukocytes and is thought to contribute to neuronal injury, death, gliosis, and demyelination. The tyrosine kinase 2 ("TYK2") and janus jinase 1 ("JAK1") signal transduction pathways mediate highly complementary immune and inflammatory signaling events. Targeted, small-molecule therapies that inhibit TYK2 or JAK kinases have separately demonstrated robust efficacy in autoimmune, dermatologic and gastrointestinal disorders. TYK2 is a validated immune target as evidenced by a recent peripheral program that gained FDA approval, and there are multiple additional peripheral non-CNS programs in clinical development. Brain penetrant inhibitors of TYK2/JAK1 have the potential to bring this validated immune target to brain disorders. There are currently no brain penetrant, selective, dual TYK2/JAK1 inhibitors approved for brain disorders. We expect to advance BHV-8000 (previously TLL-041) into a Phase 1 study in 2023. The Company is evaluating and has not yet finalized potential clinical trial designs, including trial size, and primary and secondary endpoints. Glutamate The most advanced product candidate from our glutamate receptor antagonist platform is troriluzole (previously referred to as trigriluzole and BHV- 4157), which is in two Phase 3 trials in OCD. Other product candidates include BHV-5500, which is an antagonist of the glutamate N-methyl-D-aspartate (“NMDA”) receptor. Glutamate is an important neurotransmitter present in over 90% of all brain synapses. Glutamate plays an essential role in normal brain functioning and its levels must be tightly regulated. Abnormalities in glutamate levels can disrupt nerve health and communication, and in extreme cases may lead to nerve cell death. Nerve cell dysfunction and death leads to devastating diseases, including ataxia, amyotrophic lateral sclerosis (“ALS”) and other neurodegenerative disorders. Glutamate clearance is necessary for proper synaptic activation and to prevent neuronal damage from excessive activation of glutamate receptors. Excitatory amino-acid transporters (“EAATs”) help regulate glutamate clearance, and are responsible for most of the glutamate uptake within the brain. The mechanism of action of our glutamate platform is depicted below. Glutamate must be tightly regulated once released from a pre-synaptic neuron. It acts as a signaling neurotransmitter to stimulate the post-synaptic neuron via glutamate receptors (e.g., NMDA, alpha-amino-3-hydroxy-5- methyl-4-isoxazole-propionic acid (“AMPA”) or Kainate receptors). Glial cells surrounding the synaptic junction are predominantly responsible for clearing glutamate through transporters, specifically the EAATs. There are five distinct types of glutamate transporters. The figure below depicts the areas of modulation that are affected by our product candidates. (1) As depicted in the glial cell to the right in the figure below, troriluzole increases the activity and expression of the EAATs to increase the clearance of glutamate released from the pre-synaptic neuron. Troriluzole also inhibits presynaptic ion channels that may inhibit the release of glutamate from presynaptic neurons. (2) As depicted in the postsynaptic neuron to the bottom of the figure below, BHV-5500 blocks glutamate signaling that is mediated by post-synaptic NMDA receptors. Modulating glutamate also has the potential to be neuroprotective and increase the release of neurotrophic factors, including brain derived neurotrophic factor (“BDNF”) which are endogenous molecules that help to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses. 7 Table of Contents Adapted from Glutamate abnormalities in obsessive compulsive disorder: Neurobiology, pathophysiology, and treatment, C. Pittenger, M. Bloch, and K. Williams Glutamate Transporter Modulation Abnormal glutamate release or dysfunction of glutamate clearance can cause overstimulation of glutamate receptors which can lead to a dangerous neural injury called excitotoxicity, which has been associated with a wide range of neurodegenerative diseases. The FDA has approved anti- excitotoxicity drugs that act on the glutamatergic system by blocking NMDA receptors, such as memantine (“Namenda”) for Alzheimer’s disease, lamotrigine (“Lamictal”) for epilepsy and bipolar disorder and riluzole (“Rilutek”) for ALS. Although these drugs show the therapeutic potential of glutamate receptor antagonists and other glutamate modulators in the treatment of a range of neurological diseases, these approved drugs have serious side effects and other drawbacks that we have attempted to solve with our development of troriluzole. Troriluzole Troriluzole is a new chemical entity (“NCE”) and tripeptide prodrug of the active metabolite, riluzole. Based on its mechanism of action, preclinical data and clinical studies, troriluzole has potential for therapeutic benefit in a range of neurological and neuropsychiatric illnesses. Initial development has focused on its use in treating SCA, an orphan neurological indication that currently has no approved drug therapies and for which the active metabolite, riluzole, has demonstrated preliminary efficacy in two prior randomized controlled trials conducted by third parties. Ristori et al. reported a randomized, double-blind, placebo-controlled trial of 40 patients presenting with cerebellar ataxias of diverse etiologies, including SCA. Subjects were randomized to receive 8 weeks treatment with either placebo or riluzole (50 mg Riluzole tablets, twice daily). Statistically significant improvement in the riluzole treated group was demonstrated on the International Cooperative Ataxia Rating Scale (“ICARS”). The number of patients with a 5-point ICARS drop was higher in the riluzole group than in the placebo group after 4 weeks (9/19 vs 1/19; odds ratio [“OR”] =16.2; 95% confidence interval [“CI”] 1.8–147.1) and 8 weeks (13/19 vs 1/19; OR = 39.0; 95% CI 4.2– 364.2). The mean change in the riluzole group ICARS after treatment revealed a decrease (p < 0.001) in the total score (-7.05 [4.96] vs 0.16 [2.65]). Romano et al. described results of a second randomized, placebo-controlled trial subjects diagnosed with a hereditary ataxia (including SCAs) randomized to receive 12 months of treatment with either placebo or riluzole (50 mg, twice daily). 60 patients were randomized. Statistically significant improvement in the riluzole treated group was demonstrated on the Scale for the Assessment of Ataxia (“SARA”). The proportion with decreased SARA score was 14 (50%) of 28 patients in the riluzole group versus three (11%) of 27 in the placebo group (OR 8.00, 95% CI 1.95– 32.83; p=0.002). We acquired troriluzole from ALS Biopharma, LLC (“ALS Biopharma”) and Fox Chase Chemical Diversity Center, Inc. (“FCCDC”), along with an estate of over 300 prodrugs. A prodrug is a compound that, after administration, is metabolized in the body into an active drug. Troriluzole is actively transported by virtue of recognition of its tripeptide moiety by the PepT1 transporter in the gut and is responsible for the increased bioavailability of the drug. Once inside the body, the prodrug, troriluzole is cleaved by enzymes in the blood to the parent, riluzole. To mitigate the limitations of riluzole, 8 Table of Contents several classes of prodrugs were designed, synthesized, and evaluated in multiple in vitro stability assays that predict in vivo drug levels. Troriluzole is a third generation of prodrug development and the product of six years of intensive chemistry efforts. Riluzole is currently only indicated for ALS and has a number of non-desirable attributes that have limited its clinical use. Key limitations of riluzole include poor oral bioavailability, difficulty swallowing due to tablet formulation, food reducing efficacy, liver toxicity, pharmacokinetic variability, and oral numbness. The prodrug design and selected administration pathway that was pursued with troriluzole is intended to address all of these limitations of riluzole. In addition, a prodrug can be engineered to enhance absorption and protect from diminished absorption when taken with meals. The troriluzole preclinical development strategy was based on optimizing in vivo and in vitro features, such as stability in gastrointestinal and stomach fluids; stability in liver microsomes; limiting off-target effects (particularly liver effects); metabolic cleavage in the plasma to release the active moiety; and enhanced gastrointestinal absorption properties. In in vivo studies in rodents, the intended benefits of this optimization program were observed, including delayed peak concentrations and greater exposure. After six years of chemistry development and preclinical testing, the resulting lead prodrug from the chemistry program was troriluzole. Troriluzole is chemically comprised of riluzole linked via an amide bond to a tripeptide that is a substrate for PepT1 and which contributes to its improved bioavailability. The tripeptide moiety is cleaved by plasma aminopeptidases, releasing riluzole and naturally occurring amino acids, which we believe are readily managed by endogenous metabolic routes. We believe that the estate of compounds we acquired, combined with our internally developed intellectual property, will provide a significant protection for our innovations. Troriluzole is stable in fluids from the gastrointestinal tract and expected to have a differentiated profile with regard to any liability for hepatic effects. Our Clinical Program for Troriluzole Phase 1 Studies with Troriluzole In July 2016, we began a Phase 1 randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability and pharmacokinetics (“PK”) of single and multiple ascending doses of troriluzole in normal healthy volunteers. 58 healthy volunteers were dosed with troriluzole and 20 were dosed with placebo. Both single and multiple doses up to 200 mg were well tolerated without evidence of novel, clinically significant safety signals or lab abnormalities. There was no apparent dose response regarding the frequency or severity of adverse events (“AEs”). In the blinded group, including subjects treated with both placebo and troriluzole, the most common AEs were headache (five subjects, two with moderate severity and three with mild severity) and constipation (two subjects). No pattern of AEs or lab abnormalities were apparent to provide specific cautions or to suggest cautions beyond what is appropriate for the active metabolite, riluzole. Commencing in December 2017, an additional single and multiple dose study was conducted to assess the safety, tolerability and PK of a 280 mg dose in 10 healthy young and elderly volunteers (eight active; two placebo). The results supported adequate safety and tolerability and yielded mean exposures comparable to what would be expected from a 200 mg dose, a dose that has been safely used in clinic populations and associated with efficacy in a range of disorders in randomized controlled trials (Huntington Study Group Neurology 2003; Lacomblez Neurology 1996). In addition, a bioequivalence study was conducted to bridge a commercial formulation with a Phase 2/3 formulation in 32 healthy volunteers. The commercial formulation was well-tolerated and provided bioequivalent exposure with the Phase 2/3 formulation. Troriluzole for OCD OCD is a chronic neuropsychiatric disorder characterized by symptoms of obsessions (intrusive thoughts) and compulsions (repetitive behaviors) that can interfere with patients’ functional abilities. According to the National Institute of Mental Health, the 12-month prevalence of OCD is 1% of the U.S. adult population, and approximately half of these cases are characterized as severe. First-line treatment for OCD includes cognitive behavioral therapy, selective serotonin reuptake inhibitors (“SSRIs”) and adjunctive use of atypical antipsychotics. Nonetheless, up to 60% of patients have an inadequate response to conventional intervention strategies and some seek invasive neurosurgical procedures to ameliorate symptoms. We are currently developing troriluzole as a potential treatment option for patients suffering from OCD. Despite the significant public health burden, no novel mechanisms of action have been approved by the FDA for OCD in over two decades. The rationale for use of troriluzole in OCD is supported by clinical data with its active metabolite, riluzole, in populations with OCD in open-label and placebo-controlled clinical trials as well as in preclinical, genetic and neuroimaging studies implicating the glutamatergic hyperactivity in the pathogenesis of OCD. In multiple case studies, the use of riluzole in patients with refractory OCD has commonly been associated with meaningful improvement of symptoms. A small-scale randomized controlled trial in adults with OCD conducted by a third party showed favorable trends for the use of riluzole in an outpatient setting. Another randomized controlled third-party study demonstrated statistically significant therapeutic effects with the adjunctive use of riluzole as compared to 9 Table of Contents adjunctive placebo in 50 adults with refractory OCD. These clinical effects are consistent with findings such as genetic associations of glutamate transporter genes with OCD and increased glutamate concentrations in brain and cerebrospinal fluid of patients with OCD. Taken together, we believed there was a clear rationale for advancement of troriluzole, a prodrug of riluzole, into a Phase 2 proof-of-concept trial in OCD. We commenced a Phase 2/3 double-blind, randomized controlled trial on the use of troriluzole in adults with OCD in late 2017. Results from the Phase 2/3 trial were announced in June 2020. Troriluzole 200 mg administered once daily as adjunctive therapy in OCD patients with inadequate response to standard of care treatment showed consistent numerical improvement over placebo on the Yale-Brown Obsessive Compulsive Scale (“Y- BOCS”) at all study timepoints (weeks 4 to 12) but did not meet the primary endpoint at week 12. Troriluzole treated subjects (n = 111) had a mean Y- BOCS improvement of -3.4 points from baseline versus -2.9 for placebo-treated (n = 115) subjects [difference -0.5 and p-value = 0.451] at week 4, -5.1 points (n = 96) versus -3.6 for placebo-treated (n = 108) subjects [difference -1.5 and p-value = 0.041] at week 8, and -5.9 points (n = 99) versus -4.9 for placebo-treated (n = 102) subjects [difference -1.0 and p-value = 0.220] at week 12. Troriluzole’s safety profile was generally consistent with past clinical trial experience with its active metabolite, riluzole. Treatment emergent adverse events (“TEAE”s) were mostly reported to be mild in intensity. TEAEs that occurred in at least 5% of patients in the troriluzole group, and more frequently in the troriluzole group than in the placebo group, were headache, dizziness, fatigue, somnolence, nausea and nasopharyngitis. Given the strong signal in the Phase 2/3 proof of concept study and after receiving feedback from the FDA in an End of Phase 2 meeting, in December 2020 we initiated enrollment in a Phase 3 program. The Phase 3 program will have an estimated total enrollment of 1,300 participants with a primary endpoint of change from baseline on the Y-BOCS total score at week 4, 8 and 10. The two Phase 3 randomized, double-blind, placebo- controlled trials that make-up our Phase 3 program for OCD are currently ongoing with enrollment expected to be completed in the second half of 2023. Troriluzole for Glioblastoma Preclinical and small-scale pilot studies are underway to explore troriluzole’s use in the treatment of a pipeline of other indications such as some cancers whose spread is thought mediated by glutamate transmission, such as melanoma and glioblastoma ("GBM"). In collaboration with Johns Hopkins University, we explored the potential applicability of troriluzole for GBM. The oncology collaboration Johns Hopkins was based upon the mechanistic rationale that some tumors over express glutamate receptors, the central role that glutamate may have in cancer metabolism and the effect of glutamate on the tumor microenvironment. In December 2021, the Global Coalition for Adaptive Research ("GCAR") selected troriluzole for evaluation in Glioblastoma Adaptive Global Innovative Learning Environment - NCT03970447 ("GBM AGILE"). GBM AGILE is a revolutionary patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent GBM, the most fatal form of brain cancer. Troriluzole will be evaluated in all patient subgroups of the trial which include newly-diagnosed methylated O6-methylguanine DNA methyltransferase (“MGMT”), newly-diagnosed unmethylated MGMT, and recurrent GBM. Troriluzole was selected for inclusion in GBM AGILE based on compelling evidence showing deregulation of glutamate in GBM. The therapeutic potential of troriluzole in GBM and other oncology indications is supported by several recent clinical and translational research studies conducted with troriluzole and its active moiety. For example, Medikonda et al. showed a survival benefit with troriluzole, alone and in combination with anti-programmed cell death protein-1 (“PD-1”) immunotherapy, utilizing a frequently used murine brain tumor model. C57BL/6J mice were intracranially implanted with luciferase-tagged GL261 glioma cells. Mice were randomly assigned to the control, anti-PD-1, troriluzole or combination anti-PD-1 plus troriluzole treatment arms, and median overall survival was assessed. The troriluzole treatment arm demonstrated improved survival compared with the control arm (median survival of 36% vs. 0%; p < 0.0001), as did the combination anti-PD-1 plus troriluzole treatment arm (overall survival of 80% vs. 0; p = 0.0007). In July 2022, the Company and GCAR announced that enrollment has commenced in GBM AGILE for the evaluation of troriluzole. GBM AGILE is a multi-arm, platform trial. The evaluation of each therapy in GBM AGILE proceeds in 2 possible stages. A therapy's Stage 1 is an adaptively randomized screening stage for evaluating the therapy within patient signatures compared against a common control. A therapy in Stage 1 will stop accruing patients if it reaches its maximal sample size, drops for futility, or evinces inadequate safety. If a therapy reaches an efficacy threshold for graduation from Stage 1, it will move into Stage 2 within one of the prospectively defined signatures. The maximum sample size in Stage 1 is 150 patients. For a therapy graduating to Stage 2 there is a fixed randomization, expansion cohort. The maximum sample size in Stage 2 is 50 experimental patients in the graduating signature. The primary analysis of a regimen's effect on overall survival (“OS”) uses all patients in both its stages and all control patients in the trial in the graduating signature, suitably adjusted for any possible time trends. 10 Table of Contents Troriluzole for SCA Based on the results of our Phase 1 trial with troriluzole and two third-party academic trials that have shown preliminary efficacy of riluzole in cerebellar ataxias, we advanced troriluzole into a Phase 2/3 clinical trial for SCA. Initially, we had conducted a Phase 2b/3, randomized, double-blind, placebo-controlled, parallel-group study to assess the safety and efficacy of troriluzole over 8 weeks in subjects with SCA. In October 2017, we announced that troriluzole at a dose of 140 mg once daily (“QD”) did not differentiate from placebo on the primary endpoint of the mean change from baseline on the SARA total score after 8 weeks of treatment. After eight weeks of treatment, troriluzole treated subjects (n = 63) demonstrated an improvement of –0.81 points [95% CI: –1.4 to –0.2] on the SARA versus –1.05 points [95% CI: –1.6 to –0.4] improvement in placebo-treated (n = 68), p- value = 0.52. In this trial, we observed a favorable safety and tolerability profile of troriluzole, with no drug-related serious adverse events (“SAEs”) and low discontinuation rates due to AEs. During open-label treatment over the 48-week extension phase, however, troriluzole did show slowing of disease progression in troriluzole-treated subjects in contrast to the measurable decline expected for a cohort of untreated subjects based on the natural history of the disease. Based on our learnings from the Phase 2b/3 study, including analyses from the open-label extension phase, we advanced troriluzole into a Phase 3, randomized, double-blind, placebo-controlled, parallel-group study to assess the safety and efficacy of troriluzole over 48 weeks in subjects with SCA. We enriched this trial with specific SCA genotypes, extended the treatment period of this trial to 48 weeks, implemented the use of a modified SARA scale (“f-SARA”), and increased the dose of troriluzole to 200 mg QD. Notably, the f-SARA is a novel, 16-point scale developed in collaboration with FDA as the primary outcome measure for this trial; the scale was designed to limit subjectivity of the scale and focus on functional aspects of the disease so that significant changes would be considered clinically meaningful. In May 2022, the Company announced top-line results from the Phase 3 clinical trial evaluating the efficacy and safety of its investigational therapy, troriluzole, in adult patients with SCA. The primary endpoint, change from baseline to week 48 on the f-SARA, did not reach statistical significance in the overall SCA population as there was less than expected disease progression over the course of the study. In the overall study population (n = 213), the troriluzole and placebo groups each had mean baseline scores of 4.9 on the f-SARA and the two groups showed minimal change at the 48-week endpoint with f-SARA scores of 5.1 and 5.2, respectively (p=0.76). Troriluzole was well tolerated with an adverse event profile similar to placebo. The frequency of subjects with any TEAE was 80.6% for troriluzole vs. 84.4% for placebo and the frequency of subjects with serious TEAEs was 5.6% for troriluzole vs. 7.3% for placebo. Post-hoc analysis of efficacy measures by genotype suggests a treatment effect in patients with the SCA Type 3 (“SCA3”) genotype, which represents the most common form of SCA and accounted for 41% of the study population. In the SCA3 subgroup, troriluzole showed a numerical treatment benefit on the change in f-SARA score from baseline to week 48 compared to placebo (least squares (“LS”) mean change difference -0.55, nominal p-value = 0.053, 95% CI: -1.12, 0.01). SCA patients treated with troriluzole showed minimal disease progression over the study period. Further, in patients in the SCA3 subgroup who were able to walk without assistance at baseline (i.e., f-SARA Gait Item score = 1), troriluzole demonstrated a greater numerical treatment benefit on the change in f-SARA score from baseline to week 48 compared to placebo (LS mean change difference -0.71, nominal p-value = 0.031, 95% CI: -1.36, -0.07). Across all genotypes, patients who were able to ambulate at baseline (i.e., f-SARA Gait Item score = 1) showed a reduction in the relative risk of falls in troriluzole-treated patients versus placebo. Patient reported falls, as measured by adverse events reveal an approximately 58% reduction of fall risk in the troriluzole group (10% versus 23% AE incidence of falls in the troriluzole and placebo groups, respectively; nominal p=0.043). The risk reduction of falls in the troriluzole group combined with the progression of f-SARA scores in the untreated SCA3 group compared to SCA3 patients on troriluzole demonstrates that SCA3 patients experienced a clinically meaningful improvement in ataxia symptoms on troriluzole treatment. Given these findings and the debilitating nature of SCA, we intend to interact with the FDA and or European Medicines Agency ("EMA") in the first half of 2023. We have not yet decided on the format of such a regulatory interaction but we could seek advice through various formal or informal interactions with regulatory agencies or we could choose to submit an NDA if we believe that is warranted from the results of our ongoing post-hoc analyses. There are currently no FDA-approved medications for the treatment of SCA or any other cerebellar ataxia, and treatment is supportive. In general, multidisciplinary care provides supportive measures and the goal of this treatment is to improve quality of life and survival. Glutamate NMDA Receptor Antagonism and BHV-5500 for Neuropathic Pain An NMDA receptor antagonist is a type of glutamate antagonist that works to inhibit the action of NMDA receptors which may play a role in various diseases that affect the brain. BHV-5500 (lanicemine) was in-licensed from AstraZeneca and is a low-trapping, NMDA receptor antagonist with differentiating pharmacologic properties from other agents in development targeting this receptor. The unique property of low-trapping antagonists is their ability to uncouple from the NMDA receptor more freely than other agents, a property that is thought to contribute to their mitigated risk of dissociative effects as has been observed in the clinic. Lanicemine, binds within the NMDA channel pore and functionally blocks the flow of charged ions through the NMDA receptor complex. 11 Table of Contents Neuropathic pain is a chronic condition caused by dysfunctional or damaged nerves. Neuropathic pain can be a debilitating and common problem affecting approximately 10% of adults in the United States. Despite the availability of multiple approved drugs, including Lyrica, and guidelines for the treatment of neuropathic pain, treatment of this condition remains a major therapeutic challenge. Existing analgesics are often ineffective, can cause serious side effects and have abuse potential that limits widespread use. Increased NMDA receptor activity is known to contribute to central sensitization in neuropathic pain. NMDA receptor antagonists have been shown to reduce hyperalgesia and pain in animal models of neuropathic pain induced by nerve injury and diabetic neuropathy. Clinically used NMDA receptor antagonists, including ketamine and dextromethorphan, can be effective in patients suffering from neuropathic pain syndromes. The clinical use of robust NMDA antagonists, such as ketamine, is limited due to dissociative, psychotomimetic and abuse potential properties. Novel NMDA receptor antagonists, such as BHV-5500, that are not associated with the psychotomimetic effects and abuse potential could lead to better management of neuropathic pain without causing serious side effects. MPO Verdiperstat Verdiperstat is a selective, brain-permeable, irreversible myeloperoxidase (“MPO”) enzyme inhibitor that may have potential for the treatment of neurological diseases. MPO generates an array of cytotoxic oxidants and is a key driver of oxidative and inflammatory processes that underlie a broad range of disorders. MPO plays a key role in neurodegenerative, inflammatory, and immune-mediated diseases, including multiple system atrophy (“MSA”), Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, ischemic and hemorrhagic forms of stroke, epilepsy, depression and other neuropsychiatric disorders. Clinical and experimental studies have revealed the detrimental role of MPO. Hence, suppressing MPO may be a novel treatment approach for these disorders. Verdiperstat (formerly named AZD3241) was in-licensed from AstraZeneca in September 2018. Our Clinical Program for Verdiperstat for ALS ALS is a progressive, life-threatening, and rare neuromuscular disease that affects approximately 30,000 people in the United States. The median age of onset is 55 years and average survival is 3-5 years after onset of first symptoms. ALS is characterized by the loss of motor neurons in the brain, brainstem, and spinal cord that leads to progressive muscle weakness and difficulties in speaking, swallowing, and breathing. There are currently limited treatment options and no cure for ALS. MPO may play a role in increasingly recognized ALS disease mechanisms mediated by peripheral myeloid cells, including those that migrate into the brain as well as those that remain in the periphery, suggesting relevance of MPO as a therapeutic target. In September 2019, we announced that verdiperstat was selected to be studied in the pivotal HEALEY ALS Platform Trial, which is being conducted by the Sean M. Healey & AMG Center for ALS at MGH (“Healey Center”) in collaboration with the Northeast ALS Consortium (“NEALS”) clinical trial network. Promising investigational drugs were chosen for the HEALEY ALS Platform Trial through a competitive process, with the Healey Center providing partial financial support to successful applicants. The HEALEY ALS Platform Trial is a Phase 2/3 randomized, double-blind, placebo-controlled clinical trial evaluating the safety and efficacy of investigational products for the treatment of ALS. HEALEY ALS Platform Trial Regimen B is evaluating the safety and efficacy of verdiperstat in approximately 167 adults with ALS. Participants were randomized in a 3-to-1 ratio treated with verdiperstat 600 mg BID or placebo for 24 weeks. The study's primary efficacy endpoint measures the change in disease severity from baseline to week 24 on the ALS Functional Rating Scale-Revised in patients receiving treatment versus placebo. Secondary endpoints include change in respiratory function, muscle strength, and survival. In August 2020, we announced that the first patients were enrolled in the pivotal HEALEY ALS Platform Trial Regimen B. Enrollment in the trial was completed in November 2021. In September 2022, the Company announced that verdiperstat did not statistically differentiate from placebo on the prespecified primary efficacy outcome, disease progression measured by the ALS Functional Rating Scale-Revised and survival, nor the key secondary efficacy measures during the 24-week study period. Analysis of safety data was consistent with the overall profile of verdiperstat from prior clinical trial experience. The study results have been presented at scientific meetings in 2022, including the NEALS Consortium meeting and the International Symposium on ALS/MND. Publication of these study results in an academic medical journal is pending. At this time, we do not have plans to pursue any additional clinical trials evaluating verdiperstat in ALS, and we may evaluate its potential in other disease indications. Myostatin Taldefgrobep Alfa (BHV-2000) In February 2022, we announced a worldwide license agreement with BMS for the development and commercialization rights to taldefgrobep alfa (also known as BMS-986089), a novel Phase 3 asset. Myostatin, a negative regulator of muscle growth, is a key member of the Transforming Growth Factor ("TGF") (symbol Beta) family. 12 Table of Contents Taldefgrobep novelty in a field of myostatin inhibitors is based on the mechanism where it binds to myostatin to both lower overall myostatin levels, but also to function as a receptor antagonist to block myostatin signaling in skeletal muscles. Blocking myostatin activity and signaling has shown to improve muscle function and strength in a number of disease models for neuromuscular wasting. Clinical studies have confirmed that taldefgrobep improved lean body mass directly through increase in contractile muscle and loss of adipose tissue as demonstrated in both normal healthy volunteers and in patients with Duchenne muscular dystrophy (“DMD”). The mechanism of improving overall muscle size and function opens the opportunity for taldefgrobep as a monotherapy or combination therapy in a number of muscle-targeted neuromuscular diseases. The addition of taldefgrobep alfa expanded our Neuroinnovation pipeline. The advanced taldefgrobep alfa anti-myostatin development program offers extensive human safety data, especially in the pediatric population. About Spinal Muscular Atrophy SMA is a rare genetic neurodegenerative disorder characterized by the loss of motor neurons, atrophy of the voluntary muscles of the limbs and trunk and progressive muscle weakness that is often fatal and typically diagnosed in young children. The underlying pathology of SMA is caused by insufficient production of the survival of motor neuron (“SMN”) protein, essential for the survival of motor neurons, and is encoded by two genes, SMN1 and SMN2. In the U.S., SMA affects approximately 1 in 11,000 births, and about 1 in every 50 Americans is a genetic carrier. Newborn screening is now available in 48 U.S. states and covers over 94% of all births. Our Clinical Trial for Taldefgrobep Alfa in SMA In July 2022, we commenced enrollment in a Phase 3 clinical trial assessing the efficacy and safety of taldefgrobep alfa in SMA. The Phase 3 placebo-controlled, double-blind trial is designed to evaluate the efficacy and safety of taldefgrobep as an adjunctive therapy for participants who are already taking a stable dose of nusinersen or risdiplam or have a history of treatment with onasemnogene abeparvovec-xioi, compared to placebo. The primary outcome measures of the study will be efficacy of taldefgrobep alfa compared to placebo in the change in the 32 item Motor Function Measure (“MFM-32”) total score from baseline to Week 48. Scores range from 0-3 on each item, with higher scores indicating higher functioning. The study is neither restricted nor limited to patients based on ambulatory status or classification of SMA. We expect to randomize approximately 180 patients in this randomized, double-blind, placebo-controlled global trial. In February 2023, we received Fast Track designation from the FDA for taldefgrobep alfa for the treatment of SMA. Fast Track designation enables important new drugs to reach patients earlier by facilitating more frequent communications with the FDA and expeditious review of a drug which treats a serious condition and fills an unmet 13 Table of Contents medical need. In December 2022, we received orphan drug designation from the FDA for taldefgrobep in the treatment of SMA. Taldefgrobep Alfa’s Role in Spinal Muscular Atrophy In the past three years, significant advancements were made to address the underlying cause of disease in SMA with the up-regulation of SMN1 and SMN2 expression which positions taldefgrobep as a potential combination therapy to enhance muscle performance. Data from both an SMA animal model study that shows advantages of combination SMN therapy with taldefgrobep and the extensive clinical data in DMD support the advancement of taldefgrobep into a SMA Phase 3 study. Other indications in muscle wasting diseases will be a fast follow-on for taldefgrobep along with other life-cycle opportunities. Discovery Research The Company has laboratory facilities located in Science Park in New Haven, Connecticut, in Pittsburgh, Pennsylvania, and in Cambridge, Massachusetts supporting our integrated chemistry and discovery research operations. We will continue to augment our discovery efforts through research partnerships, including research agreements such as with KU Leuven and the Fox Chase Chemical Diversity Center Inc.. TRPM3 Antagonists KU Leuven Agreement In January 2022, we entered into the KU Leuven Agreement to develop and commercialize TRPM3 antagonists to address the growing proportion of people worldwide living with chronic pain disorders (the "KU Leuven Agreement"). The TRPM3 antagonist platform was discovered at the Centre for Drug Design and Discovery and the Laboratory of Ion Channel Research at KU Leuven. Under the KU Leuven Agreement, we receive exclusive global rights to develop, manufacture and commercialize KU Leuven's portfolio of small-molecule TRPM3 antagonists. The portfolio includes the lead candidate, BHV-2100, which we are evaluating in several preclinical pain models and advancing towards the clinic in 2023. We are continuing to support further basic and translational research on the role of TRPM3 in pain and other disorders through our collaboration with Professors Joris Vriens and Thomas Voets, world leaders in TRP biology at KU Leuven. Efforts to target TRP Channels for pain Since the Nobel Prize-winning discovery of the capsaicin receptor TRPV1 in 1997, members of the Transient Receptor Potential (“TRP”) cation channel family have been elusive drug targets for the treatment of pain. Initially, there was much excitement and investment in TRPV1 antagonists due to promising preclinical efficacy and some evidence of clinical pain reduction. However, trials of most TRPV1 antagonists were terminated after the class consistently caused clinically-significant hyperthermia in study participants. Several companies then made efforts to progress antagonists of TRPA1, the receptor for mustard oil. Though Glenmark’s GRC 17536 showed encouraging results in a subset of diabetic peripheral neuropathic pain subjects in a Phase 2a study, it suffers from poor physiochemical properties and pharmacokinetics like many other TRPA1 antagonists. Due to the challenges with drugging TRPA1, only Eli Lilly’s LY3526318 remains in active clinical development. TRPM3 is a novel target in the TRP family. Like TRPV1 and TRPA1, preclinical data and human genetic validation support TRPM3’s role in neuropathic pain. Unlike TRPV1 antagonists, TRPM3 antagonists are unlikely to possess significant thermal liabilities, and unlike TRPA1 antagonists, Biohaven’s TRPM3 antagonists have desirable 14 Table of Contents physiochemical properties and good pharmacokinetic profiles. The figure below illustrates TRPM3 as a differentiated target for the treatment of pain in the TRP family. Adapted from Efforts to target TRP channels for pain, Kovivisto et al. 2022 About TRPM3 Transient Receptor Potential Melastatin 3 (“TRPM3”) is a novel druggable target in the TRP cation channel family. TRPM3 is functionally expressed in the human dorsal root ganglion, and several SNPs in TRPM3 are associated with altered pain sensation in response to UVB (see figure below). Additionally, people with TRPM3 gain-of-function mutations experience altered pain sensation (de Sainte Agathe 2020, Dyment 2019, Van Hoeymissen 2020). Knocking out or antagonizing TRPM3 in animal models attenuates the development of various pain states, including those associated with nerve injury, chemotherapy, and diabetic peripheral neuropathy, further indicating that TRPM3 is a promising target for neuropathic pain. Lastly, preclinical evidence suggests that antagonizing TRPM3 may avoid the on-target body temperature effects and TRPV1 antagonist-induced malignant hyperthermia. Vangeel et al, 2020 Lotsch et al, 2020 Our Development of BHV-2100 for the Treatment of Neuropathic Pain BHV-2100 is an orally-bioavailable small molecule antagonist of TRPM3. TRPM3 is expressed in the relevant human tissue types for neuropathic pain, and both preclinical models and human genetics implicate TRPM3 in pain signaling. BHV-2100 is our lead orally-bioavailable small molecule TRPM3 antagonist which we are developing as a potential non-opioid treatment for neuropathic pain. We are evaluating the ability of BHV-2100 to reduce pain behaviors across several 15 Table of Contents preclinical models of neuropathic pain, including chemotherapy induced neuropathy, diabetic neuropathy, and nerve injury. We expect to submit an IND application for BHV-2100 with the FDA in the second half of 2023, complementing our efforts with our Kv7 platform. The Company is evaluating and has not yet finalized potential clinical trial designs, including trial size, and primary and secondary endpoints. Additional research on TRPM3-mediated disorders Under the KU Leuven agreement, Biohaven is supporting further basic and translational research at KU Leuven on the role of TRPM3 in pain and other disorders. In addition to BHV-2100, we are optimizing other lead compounds for TRPM3-mediated disorders of the peripheral and central nervous systems. Bispecific Molecular Degraders of Extracellular Proteins Molecular Degraders of Extracellular Proteins (“MoDEs”) are bispecific molecules that target pathologic circulating proteins and direct them to the liver (or other organ systems) for degradation by the endosomal/lysosomal pathway. Our MoDE platform is being explored for use in a wide range of therapeutic areas, including indications in autoimmune diseases, cancer and infectious disease. We are generally planning for MoDEs to be administered as intravenous or subcutaneous formulations. The Company is evaluating and has not yet finalized potential clinical trial designs, including trial size, and primary and secondary endpoints. Antibody-based Galactose-deficient IgA (“Gd-IgA”) MoDEs IgA nephropathy (“IgAN”) is the most common primary glomerulonephritis that can progress to renal failure and is characterized by immunoglobulin deposits in the renal mesangium comprised exclusively of the IgA1 subclass. Patients with IgAN have increased serum levels of IgA1 with a hinge region containing truncated galactose-deficient O-linked saccharides (“Gd-IgA”) and can present with a range of symptoms, from hematuria or proteinuria to severe hypertension owing to renal damage. The clinical progression varies, with 30–40% of patients reaching end-stage renal disease 20–30 16 Table of Contents years after the first clinical presentation. Currently, no IgAN-specific therapies are available. Patients are managed with the aim of controlling blood pressure and maintaining renal function. Lai, Nat Rev Dis Primers (2016) We are leveraging our MoDE platform to develop novel bispecific molecules for the treatment of IgA nephropathy (“IgAN”) that remove potentially disease-causing Gd-IgA or total IgA in patients and prevent harmful kidney deposits. We have taken a published rodent format IgG antibody that recognizes Gd-IgA and converted it into a partially-humanized, liver-targeted degrader MoDE using Multimodal Antibody Therapy Enhancer ("MATE") conjugation that potently binds Gd-IgA and causes its endocytosis in human liver cells. Further work is ongoing to progress this as a potential IgAN treatment. Therapeutic pan-IgG depletion Analogous to the depletion of pan-IgA or dg-IgA with molecular degraders, hepatic asialoglycoprotein receptor ("ASGPR") ligand degraders able to recognize all potentially pathogenic isoforms of IgG represent a novel, competitive platform with differentiated profile relative to FcRN inhibitors. FcRN inhibitors such as efgartigimod (Vyvgart) and nipocalimab also deplete IgG. Specifically, high circulating levels of antibodies (monoclonal or polyclonal gammopathy) drive conditions such as myasthenia gravis, rheumatoid arthritis, systemic lupus erythematosus, pemphigus vulgaris and many other diseases. It is hypothesized that rapid and sustained lowering of pathogenic antibody titers in blood will significantly reduce disease symptoms. As this has been shown with FcRN inhibitors for myasthenia gravis (Vyvgard), therapeutic pan-IgG depletion using Biohaven’s proprietary MoDE platform technology is expected to have significant potential benefit for multiple diseases including but not limited to the conditions outlined above. Drug candidates utilizing this technology are in nonclinical development, approaching IND. The following graphic shows preclinical data validating this approach. The effect of a single dose of our IgG degrader MoDE, BHV-1300, was evaluated in cynomolgus monkeys. BHV-1300 demonstrated robust reduction of IgG levels, with 75% depletion from baseline. This effect was rapid, occurring by 3 days. For comparison, published data with the standard 17 Table of Contents of care, efgartigimod, are included below, noting that reduction of IgG levels with efgartigimod is 50% and takes 5-7 days to achieve. The Company expects to submit an IND application for BHV-1300 with the FDA in the second half of 2023. MATE Conjugation Technology Antibody Drug Conjugates We are using the MATE conjugation technology to generate site-specific antibody drug conjugates (“ADC”s) from native IgG1 proteins that we believe will show superior stability in comparison with those using current industry-standard cysteine maleimide conjugation. Our expectation is that the enhanced in vivo stability and expected superior physicochemical properties of these ADCs will lead to increased therapeutic indices (more cytotoxic payload reaching cancer cells and less reaching normal tissues). Over 15 site-specific ADCs using the well validated valine-citrulline monomethyl auristatin E ("vcMMAE") payload linker system have been prepared and are undergoing biological testing in comparison with industry standard maleimide conjugated ADCs. MATE Molecule 18 Table of Contents BHV-1100 Antibody Recruiting Molecules Antibody Recruiting Molecules (“ARMs”) are bispecific molecules that recruit endogenous antibodies to target cancer, virally infected cells, and disease-causing microorganisms for immune-mediated clearance. These molecules are engineered as modular components that are readily interchangeable, giving the platform tremendous flexibility for a variety of indications and therapy areas. By recruiting antibodies to coat the disease cell target, ARMs mark it for removal by the body’s innate antibody-mediated immune mechanisms (antibody dependent cellular cytotoxicity and antibody dependent cellular phagocytosis). Platform advantages Similar to biologics, ARMs directly engage patients’ immune system to destroy disease cells by connecting target disease cells with components of the immune system. However, unlike biologics, ARMs are smaller in size than an antibody potentially allowing for enhanced tumor penetration and biodistribution, and may offer manufacturing advantages including enhanced shelf stability. ARM™ NK Combination Therapy ARMs provide target specificity to Natural Killer (“NK”) cell therapies without needing to design chimeric antigen receptors (“CARs”) or other methods of genetic manipulation. NK cells are a type of immune effector cell that can recognize and destroy non-self targets and certain diseased cells. NK cells do not target specific protein epitopes like T cells of the adaptive immune system. Our ARMs are being used to provide antigen target specificity to NK cell therapies (both allogeneic and autologous) with the goal of enhancing efficacy and safety. ARM NK combination therapy directs NK cells to a disease target of interest. Our Clinical Trial for BHV-1100 in Newly Diagnosed Multiple Myeloma Patients We have initiated dosing in a Phase 1a/1b trial in newly diagnosed multiple myeloma patients. Our ARM, BHV-1100, in combination with autologous cytokine induced memory-like (“CIML”) NK cells and immune globulin (“Ig”), is expected to target and kill multiple myeloma cells expressing the cell surface protein CD38. The trial is supported by compelling preclinical data showing that BHV-1100 enhanced recruitment of autologous CIML NK cells increases killing of multiple myeloma cells. This open-label single center Phase 1a/1b study assesses the safety and tolerability as well as exploratory efficacy endpoints in newly diagnosed multiple myeloma patients who have tested positive for minimal residual disease (“MRD+”) in first remission prior to autologous stem cell transplant (“ASCT”). We expect to enroll 30 newly diagnosed multiple 19 Table of Contents myeloma patients. The primary outcome measures are dose limiting toxicities following combination product administration (time frame: 100 days post- combination product administration) and incidence and severity of side effects related to the combination product (time frame: 90 to 100 days post- combination product administration). BHV-1100 Binds CD38 and lg to Create a Targeting Therapy to Kill Multiple Myeloma Cells BHV-1100 Enhances Recruitment of NK Cells and Increases Killing of Multiple Myeloma Cells University of Connecticut License Option In October 2018, we signed an exclusive, worldwide option and license agreement with the University of Connecticut for the development and commercialization rights to UC1MT, a therapeutic antibody targeting extracellular metallothionein ("MT"). Under this agreement, we had the option to acquire an exclusive, worldwide license to UC1MT and its underlying patents to develop and commercialize throughout the world in all human indications, which we exercised in September 2022. 20 Table of Contents Extracellular MT has been implicated in the pathogenesis of autoimmune and inflammatory diseases. MTs are a family of low molecular weight, cysteine-rich, metal-binding proteins that have a wide range of functions in cellular homeostasis and immunity. MT has traditionally been considered to be an intracellular protein that can be found in both the cytoplasm and nucleus; however, MT also can be found in extracellular spaces, particularly in disease states involving chronic cellular stress where intracellular MT production is upregulated by inflammatory cytokines, and extracellular MT acts as a danger signal, attracting leukocytes and modulating the immune response. In preclinical studies, UC1MT has been observed to block this extracellular pool of MT and the resulting MT-mediated inflammation and immunomodulation. The Company is evaluating and has not yet finalized potential clinical trial designs, including trial size, and primary and secondary endpoints. Artizan Biosciences Inc License Option In December 2020, we entered into an Option and License Agreement with Artizan Biosciences Inc ("Artizan"), a biotechnology company focused on creating new classes of precision therapies targeting chronic inflammation and immune dysregulation by leveraging the human gut as a drug discovery tool. Pursuant to the agreement, we acquired an option to obtain a royalty-based license from Artizan to manufacture, use and commercialize certain products. Artizan will use the proceeds to continue advancing the preclinical research and development of its lead program for inflammatory bowel disease as well as to explore additional disease targets. In November 2021, we announced a collaborative therapeutic discovery and development program in Parkinson’s disease (“PD”), to exploit recent scientific advances in the understanding of pathogenic roles played by the gut microbiome in PD. In June 2022, we and Artizan executed a non-binding indication of interest (“Artizan Side Letter”) which describes terms under which we and Artizan would amend the 2020 Artizan Agreement to eliminate certain milestone payments required by us in exchange for limiting our option to the selection of the first (ARZC-001) licensed product. In the fourth quarter of 2022, Artizan was unable to secure additional financing to support it's ongoing operations, and, as a result, began reviewing strategic options for the sale of its assets, and secured a small bridge financing to fund operations during the strategic review. In January, Artizan severed substantially all of its employees and halted the PD program. Although Artizan anticipates bringing the inflammatory bowel disease program to the clinic in 2023, its ability to do so will be dependent on its access to adequate funding. Competition The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a strong emphasis on proprietary drugs. While we believe that our knowledge, experience and scientific resources provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their safety, efficacy, convenience, price, the level of generic competition and the availability of coverage and reimbursement from government and other third-party payors. Many of the companies against which we are competing, or against which we may compete in the future, have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. 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 21 Table of Contents 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. Manufacturing We have an experienced chemistry and manufacturing leadership team that manages our relationships with third party manufacturers. We currently rely, and expect to continue to rely, on third parties for the development and manufacturing of our product candidates for preclinical and clinical testing, as well as for commercial manufacturing of our products if our product candidates receive marketing approval. We expect to continue to develop product candidates that can be produced cost-effectively at contract manufacturing facilities. Commercialization We intend to develop and, if approved by the FDA, commercialize our product candidates in the United States, and we may enter into distribution or licensing arrangements for commercialization rights for other regions. With respect to our product candidates, we currently intend to build a neurological specialty sales force to manage commercialization for these product candidates, potentially in combination with a larger pharmaceutical partner, to maximize patient coverage in the United States and to support global expansion. Members of our management team and board of directors have deep experience leading neuroscience research and have been involved in the development and commercialization of drugs such as Abilify, Opdivo and, most recently, Nurtec ODT. Our Chief Executive Officer, Vlad Coric, M.D. was the Chief Executive Officer of the Former Parent from 2015 through the Separation, leading the Former Parent’s development and successful commercial launch of Nurtec ODT (rimegepant) in the U.S., which received FDA approval for the acute and preventative treatment of migraine in February 2020 and May 2021, respectively. Under Dr. Coric’s leadership, the Former Parent entered into several strategic arrangements, including its Collaboration and License agreement with Pfizer, Inc. for the development of rimegepant and zavegepant outside of the United States. Intellectual Property We own or license patents in the U.S. and foreign countries that protect our products, their methods of use and manufacture, as well as other innovations relating to the advancement of our science to help bring new therapies to patients. We also develop brand names and trademarks for our products to differentiate them in the marketplace. We consider the overall protection of our patents, trademarks, licenses and other intellectual property rights to be of material value and act to protect these rights from infringement. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business, defend and enforce our patents, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable patents and other proprietary rights of third parties. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and maintain the proprietary position of our products and development programs. In the biopharmaceutical industry, a substantial portion of an innovative product’s commercial value is usually realized during the period in which the product has market exclusivity. A product’s market exclusivity is generally determined by two forms of intellectual property: patent rights held by the innovator company and any regulatory forms of exclusivity to which the innovative drug is entitled. Patents are a key determinant of market exclusivity for most pharmaceuticals. Patents provide the innovator with the right to exclude others from practicing an invention related to the medicine. Patents may cover, among other things, the active ingredient(s), various uses of a drug product, discovery tools, pharmaceutical formulations, drug delivery mechanisms and processes for (or intermediates useful in) the manufacture of products. Protection for individual products extends for varying periods in accordance with the expiration dates of patents in the various countries. The protection afforded, which may also vary from country to country, depends upon the type of patent, its scope of coverage and the availability of meaningful legal remedies in the country. Market exclusivity can also be influenced by regulatory data protection ("RDP"). Many developed countries provide certain non- patent incentives for the development of medicines. For example, in the U.S., the EU, United Kingdom, Japan, and certain other countries, RDP intellectual property rights are offered to: (i) provide a time period of data protection during which a generic company is not allowed to rely on the innovator’s data in seeking approval; (ii) restore patent term lost during drug development and approval; and (iii) provide incentives for research on medicines for rare diseases, or orphan drugs, and on medicines useful in treating pediatric patients. These incentives can extend the market exclusivity period on a product beyond the patent term.

Licensing and Other Agreements In addition to our independent efforts to develop and market products, we enter into agreements such as licensing agreements, option-to-license agreements and strategic collaborations. The licensing and other agreements typically include, among other terms and conditions, non-refundable upfront license fees, option fees and option exercise payments, milestone payments and royalties. See Note 11, "Licensing and Other Agreements," to the Consolidated Financial Statements included in this report for additional information regarding our licenses and other agreements. Government Regulation In the United States, the FDA regulates drugs under the Federal Food, Drug and Cosmetic Act ("FDCA") and its implementing regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval may subject an applicant and/or sponsor to a variety of administrative or judicial sanctions, including imposition of a clinical hold, refusal by the FDA to approve applications, withdrawal of an approval, import/export delays, issuance of warning letters and other types of enforcement letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement of profits, or civil or criminal investigations and penalties brought by the FDA and the Department of Justice or other governmental entities. The clinical testing, manufacturing, labeling, storage, distribution, record keeping, advertising, promotion, import, export and marketing, among other things, of our product candidates are governed by extensive regulation by governmental authorities in the United States and other countries. The FDA, under the FDCA, regulates pharmaceutical products in the United States. Key steps required before a drug may be approved for marketing in the United States generally include: • preclinical laboratory tests and animal tests conducted under Good Laboratory Practices ("GLP"); • the submission to the FDA of an investigational new drug ("IND") application for human clinical testing, which must become effective before human clinical trials commence; • approval by an independent institutional review board ("IRB"), representing each clinical site before each clinical trial may be initiated; • adequate and well-controlled human clinical trials to establish the safety and efficacy of the product for each indication and conducted in accordance with Good Clinical Practices ("GCP"); • the preparation and submission to the FDA of a New Drug Application ("NDA"); • FDA acceptance, review and approval of the NDA, which might include an Advisory Committee review; • satisfactory completion of an FDA inspection of the manufacturing facilities at which the product, or components thereof, are made to assess compliance with current Good Manufacturing Practices ("cGMPs"). The testing and approval process requires substantial time, effort and financial resources, and the receipt and timing of any approval is uncertain. The FDA may suspend clinical trials at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Preclinical and Human Clinical Trials in Support of an NDA Preclinical studies include laboratory evaluations of the product candidate, as well as in vitro and animal studies to gather information on the safety and activity of the product candidate. The conduct of preclinical trials is subject to federal regulations and requirements including GLP regulations. The results of the preclinical studies, together with manufacturing information and analytical data, among other things, are submitted to the FDA as part of the IND, which must become effective 26 Table of Contents before clinical trials may be commenced. The IND will become effective automatically 30 days after receipt by the FDA, unless the FDA raises concerns or questions about the conduct of the trials as outlined in the IND prior to that time. In this case, the IND sponsor and the FDA must resolve any outstanding concerns before clinical trials can proceed. The FDA may nevertheless initiate a clinical hold after the 30 days if, for example, a deficiency is found in the IND application. Clinical trials involve the administration of the product candidate to human subjects under the supervision of qualified investigators in accordance with GCP requirements. Each clinical trial must be reviewed and approved by an Institutional Review Board ("IRB") at each of the sites at which the trial will be conducted. The IRB will consider, among other things, ethical factors, the safety of human subjects and the possible liability of the institution. Clinical trials are typically conducted in three sequential phases prior to approval, but the phases may overlap or be combined. These phases generally include the following: Phase 1. Phase 1 clinical trials represent the initial introduction of a product candidate into human subjects, frequently healthy volunteers. In Phase 1, the product candidate is usually tested for safety, including adverse effects, dosage tolerance, absorption, distribution, metabolism, excretion and pharmacodynamics. Phase 2. Phase 2 clinical trials usually involve studies in a limited patient population with a specific disease or condition to (1) evaluate the efficacy of the product candidate for specific indications, (2) determine dosage tolerance and optimal dosage and (3) identify possible adverse effects and safety risks. Phase 3. If a product candidate is found to be potentially effective and to have an acceptable safety profile in Phase 2 clinical trials, the clinical trial program will be expanded to Phase 3 clinical trials to further demonstrate clinical efficacy, optimal dosage and safety within an expanded patient population at geographically dispersed clinical trial sites. These clinical studies are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product approval and labeling. Phase 4. Clinical trials may be conducted after approval to gain additional experience from the treatment of patients in the intended therapeutic indication and to document a clinical benefit in the case of drugs approved under accelerated approval regulations, or when otherwise requested by the FDA in the form of post-market requirements or commitments. Failure to promptly conduct any required Phase 4 clinical trials could result in enforcement action or withdrawal of approval. A Phase 2/3 trial design, which we have used in our troriluzole development program, is often used in the development of pharmaceutical and biological products. The trial includes Phase 2 elements, such as an early interim analysis of safety or activity, and Phase 3 elements, such as larger patient populations with less restrictive enrollment criteria. The early interim analysis of clinical or physiologic activity and/or safety allows the study to be stopped, changed or continued before a large number of patients have been enrolled, while still allowing all data from enrolled patients to count in the analysis used to support approval. Submission and Review of an NDA The results of preclinical studies and clinical trials, together with detailed information on the product's manufacture, composition, quality, controls and proposed labeling, among other things, are submitted to the FDA in the form of an NDA, requesting approval to market the product. The application must be accompanied by a significant user fee payment, which typically increases annually, although waivers may be granted in limited cases. The FDA has substantial discretion in the approval process and may refuse to accept an application if they determine that the data are insufficient for approval and require additional preclinical, clinical or other studies. Once an NDA has been accepted for filing, which occurs, if at all, 60 days after submission, the FDA sets a user fee goal date that informs the applicant of the specific date by which the FDA intends to complete its review. A standard review is 10 months from the date the application is accepted for filing and a priority review is 6 months from the date the application is accepted for filing. The review process can be extended by FDA requests for additional information or clarification. The FDA reviews NDAs to determine, among other things, whether the proposed product is safe and effective for its intended use, and whether the product is being manufactured in accordance with cGMPs to assure and preserve the product's identity, strength, quality and purity. Before approving an NDA, the FDA typically will inspect the facilities at which the product is manufactured and will not approve the product unless the manufacturing facilities comply with cGMPs. Additionally, the FDA will typically inspect one or more clinical trial sites, as well as the Sponsor of the NDA, for compliance with GCP and integrity of the data supporting safety and efficacy. During the approval process, the FDA also will determine whether a risk evaluation and mitigation strategy ("REMS") is necessary to assure the safe use of the product post approval. If the FDA concludes a REMS is needed, the sponsor of the application must submit a proposed REMS, and the FDA will not approve the application without an approved REMS, if required. A REMS can substantially increase the costs of obtaining approval. The FDA could also require a special warning, known as a boxed warning, to be included in the product label in order to highlight a particular safety risk. The FDA may also convene an advisory committee of external experts to provide input on certain review 27 Table of Contents issues relating to risk, benefit and interpretation of clinical trial data. The FDA may delay approval of an NDA if applicable regulatory criteria are not satisfied and/or the FDA requires additional testing or information. The FDA may require post-marketing testing and surveillance to monitor safety or efficacy of a product. requirements and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. On the basis of the FDA's evaluation of the NDA and accompanying information, including the results of the inspection of the manufacturing facilities, the FDA will issue either an approval of the NDA or a Complete Response Letter ("CRL"), detailing the deficiencies in the submission and the additional testing or information required for reconsideration of the application. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical studies. If a CRL is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, withdraw the application, or request a hearing. Even with submission of this additional information, the FDA may ultimately decide that the application does not satisfy the regulatory criteria for approval. Post-Approval Requirements Approved drugs that are manufactured or distributed in the United States pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims and some manufacturing and supplier changes are subject to prior FDA review and approval. There also are continuing, annual program user fee requirements for marketed products. The FDA may impose a number of post-approval requirements as a condition of approval of an NDA. For example, the FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance programs to further assess and monitor the product's safety and effectiveness after commercialization. The FDA may also require a REMS, which could involve requirements for, among other things, medication guides, special trainings for prescribers and dispensers, patient registries, and elements to assure safe use. In addition, entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. The FDA has promulgated specific requirements for drug cGMPs. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP Once an approval is granted, the FDA may issue enforcement letters or withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Corrective action could delay product distribution and require significant time and financial expenditures. Later discovery of previously unknown problems with a product, including AEs of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things: • restrictions on the marketing or manufacturing of the product, suspension of the approval, complete withdrawal of the product from the market or product recalls; • • fines, warning letters or holds on post-approval clinical trials; refusal of the FDA to approve applications or supplements to approved applications, or suspension or revocation of product approvals; • product seizure or detention, or refusal to permit the import or export of products; or • injunctions or the imposition of civil or criminal penalties. The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off- label uses may be subject to significant liability, including investigation by federal and state authorities. Section 505(b)(2) NDAs As an alternative path to FDA approval for modifications to formulations or uses of drugs previously approved by the FDA, an applicant may submit an NDA under Section 505(b)(2) of the FDCA. Section 505(b)(2) was enacted as part of the Hatch-Waxman Amendments. A Section 505(b)(2) NDA is an application that contains full reports of investigations of safety and effectiveness, but where at least some of the information required for approval comes from studies 28 Table of Contents not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference or use from the company by or for whom the investigations were conducted. This type of application permits reliance for such approvals on literature or on an FDA finding of safety, effectiveness or both for an approved drug product. As such, under Section 505(b)(2), the FDA may rely, for approval of an NDA, on data not developed by the applicant. The FDA may also require companies to perform additional studies or measurements, including clinical trials, to support the change from the approved branded reference drug. The FDA may then approve the new product candidate for the new indication sought by the 505(b)(2) applicant. Our clinical program for troriluzole for the treatment of SCA and the treatment of OCD is based on a regulatory pathway under section 505(b)(2) of the FDCA that allows reference to data on riluzole for the purpose of safety assessments. Product Exclusivity - United States In the United States, biopharmaceutical products are protected by patents with varying terms depending on the type of patent and the filing date. A significant portion of a product’s patent life, however, is lost during the time it takes an innovative company to develop and obtain regulatory approval of a new drug. As compensation at least in part for the lost patent term due to regulatory review periods, the innovator may, depending on a number of factors, apply to the government to restore lost patent term by extending the expiration date of one patent up to a maximum term of five years, provided that the extension cannot cause the patent to be in effect for more than 14 years from the date of drug approval. A company seeking to market an innovative pharmaceutical in the U.S. must submit a complete set of safety and efficacy data to the FDA. If the innovative pharmaceutical is a chemical product, the company files an NDA. If the medicine is a biological product, a Biologic License Application ("BLA") is filed. The type of application filed affects regulatory data protection (“RDP”) exclusivity rights. Small Molecule Products A competitor seeking to launch a generic substitute of small molecule drug in the U.S. must file an Abbreviated New Drug Application ("ANDA") with the FDA. In the ANDA, the generic manufacturer needs to demonstrate only “bioequivalence” between the generic substitute and the approved NDA drug. The ANDA relies upon the safety and efficacy data previously filed by the innovator in its NDA. An innovator company is required to list certain of its patents covering the medicine with the FDA in what is commonly known as the FDA’s Orange Book. The FDA cannot approve an ANDA until after the innovator’s listed patents expire unless there is a successful patent challenge. However, after the innovator has marketed its product for four years, a generic manufacturer may file an ANDA and allege that one or more of the patents listed in the Orange Book under an innovator’s NDA is either invalid or not infringed (a Paragraph IV certification). The innovator then must decide whether to file a patent infringement suit against the generic manufacturer. From time to time, ANDAs, including Paragraph IV certifications, could be filed with respect to certain of our products. In addition to patent protection, certain innovative pharmaceutical products can receive periods of regulatory exclusivity. An NDA that is designated as an orphan drug can receive seven years of exclusivity for the orphan indication. During this time period, neither NDAs nor ANDAs for the same drug product can be approved for the same orphan use. A company may also earn six months of additional exclusivity for a drug where specific clinical studies are conducted at the written request of the FDA to study the use of the medicine to treat pediatric patients, and submission to the FDA is made prior to the loss of basic exclusivity. Medicines approved under an NDA can also receive several types of RDP. An innovative chemical pharmaceutical product is entitled to five years of RDP in the U.S., during which the FDA cannot approve generic substitutes. If an innovator’s patent is challenged, as described above, a generic manufacturer may file its ANDA after the fourth year of the five-year RDP period. A pharmaceutical drug product that contains an active ingredient that has been previously approved in an NDA, but is approved in a new formulation, but not for the drug itself, or for a new indication on the basis of new clinical studies, may receive three years of RDP for that formulation or indication. Biologic products The ACA, which includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, created an approval pathway for biosimilar versions of innovative biological products that did not previously exist. Prior to that time, innovative biologics had essentially unlimited regulatory exclusivity. Under the new regulatory mechanism, the FDA can approve products that are similar to (but not generic copies of) innovative biologics on the basis of less extensive data than is required by a full BLA. After an innovator has marketed its product for four years, any manufacturer may file an application for approval of a “biosimilar” version of the innovator product. However, although an application for approval of a biosimilar version may be filed four years after approval of the innovator product, qualified innovative biological products will receive 12 years of regulatory exclusivity, meaning that the FDA may not approve a biosimilar version until 12 years after the innovative biological product was first approved by the FDA. The law also provides a mechanism for innovators to enforce the patents that protect innovative biological products and for biosimilar applicants to challenge the patents. Such patent litigation may begin as early as four years after the innovative biological product is first approved by the FDA. 29 Table of Contents In the U.S., the increased likelihood of generic and biosimilar challenges to innovators’ intellectual property has increased the risk of loss of innovators’ market exclusivity. First, generic companies have increasingly sought to challenge innovators’ basic patents covering major pharmaceutical products. Second, statutory and regulatory provisions in the U.S. limit the ability of an innovator company to prevent generic and biosimilar drugs from being approved and launched while patent litigation is ongoing. As a result of all of these developments, it is not possible to predict the length of market exclusivity for a particular product with certainty based solely on the expiration of the relevant patent(s) or the current forms of regulatory exclusivity. Foreign Regulation In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Although many of the issues discussed above with respect to the United States apply similarly in the context of the European Union and other geographies, the approval process 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 from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others. European Union A typical route used by innovator companies to obtain marketing authorization of pharmaceutical products in the EU is through the “centralized procedure.” A company seeking to market an innovative pharmaceutical product through the centralized procedure must file a complete set of safety data and efficacy data as part of a Marketing Authorization Application ("MAA") with the EMA. After the EMA evaluates the MAA, it provides a recommendation to the European Commission ("EC") and the EC then approves or denies the MAA. Regulatory approval via the centralized procedure results in a marketing authorization for the innovative pharmaceutical product in each EU member state. It is also possible for new chemical products to obtain marketing authorization in the EU through a “mutual recognition procedure,” in which an application is made to a single member state, and if the member state approves the pharmaceutical product under a national procedure, then the applicant may submit that approval to the mutual recognition procedure of some or all other member states. After obtaining marketing authorization approval, a company must obtain pricing and reimbursement for the pharmaceutical product, which is typically subject to member state law. In certain EU countries, this process can take place simultaneously while the product is marketed but in other EU countries, this process must be completed before the company can market the new product. The pricing and reimbursement procedure can take months and sometimes years to complete. Throughout the EU, all products for which marketing authorizations have been filed after October/November 2005 are subject to an “8+2+1” regime. Eight years after the innovator has received its first community authorization for a medicinal product, a generic company may file a MAA for that product with the health authorities. If the MAA is approved, the generic company may not commercialize the product until after either 10 or 11 years have elapsed from the initial marketing authorization granted to the innovator. The possible extension to 11 years is available if the innovator, during the first eight years of the marketing authorization, obtains an additional indication that is of significant clinical benefit in comparison with existing treatments. For products that were filed prior to October/November 2005, there is a 10-year period of data protection under the centralized procedures and a period of either six or 10 years under the mutual recognition procedure (depending on the member state). In contrast to the U.S., patents in the EU are not listed with regulatory authorities. Generic versions of pharmaceutical products can be approved after data protection expires, regardless of whether the innovator holds patents covering its drug. Thus, it is possible that an innovator may be seeking to enforce its patents against a generic competitor that is already marketing its product. Also, the European patent system has an opposition procedure in which generic manufacturers may challenge the validity of patents covering innovator products within nine months of grant. In general, EU law treats chemically-synthesized drugs and biologically-derived drugs the same with respect to intellectual property and data protection. In addition to the relevant legislation and annexes related to biologic medicinal products, the EMA has issued guidelines that outline the additional information to be provided for biosimilar products, also known as generic biologics, in order to review an application for marketing approval. Japan In Japan, medicines of new chemical entities are generally afforded eight years of data exclusivity for approved indications and dosage. Patents on pharmaceutical products are enforceable. Generic copies can receive regulatory approval after data exclusivity and patent expirations. As in the U.S., patents in Japan may be extended to compensate for the patent term lost during the regulatory review process. In general, Japanese law treats chemically-synthesized and biologically-derived drugs the same with respect to intellectual property and market exclusivity. China To obtain marketing authorization of pharmaceutical products in China, an NDA must be submitted to the National Medical Products Administration ("NMPA") once safety and efficacy has been established in Chinese patients. For imported 30 Table of Contents drugs, this means issuance of an import license. The applicant must submit evidence of foreign approval (certificate of pharmaceutical product), unless it is an innovative drug that has never been approved anywhere in the world. In China, medicines of new chemical entities are generally afforded 6 years of data exclusivity for approved indications and dosage. Generic copies can receive regulatory approval after data exclusivity and patent expirations. South Korea To obtain marketing authorization of pharmaceutical products in South Korea, a marketing application must be submitted to the Ministry of Food and Drug Safety ("MFDS"). The application must contain data in South Korean patients, information regarding safety and efficacy, quality, a good manufacturing practice certificate, and a certificate of pharmaceutical product in an approved country to show that the drug being imported is being sold in the approved country in accordance with the with the relevant rules and regulations in that country. In South Korea, medicines of new chemical entities are generally afforded 6 years of data exclusivity for first approved indications and dosage. Generic copies can receive regulatory approval after data exclusivity and patent expirations. Rest of the World In countries outside of the U.S., the EU, Japan, China and South Korea, there is a wide variety of legal systems with respect to intellectual property and market exclusivity of pharmaceuticals. Most other developed countries utilize systems similar to either the U.S. or the EU. Among developing countries, some have adopted patent laws and/or regulatory exclusivity laws, while others have not. Some developing countries have formally adopted laws in order to comply with World Trade Organization ("WTO") commitments, but have not taken steps to implement these laws in a meaningful way. Enforcement of WTO actions is a long process between governments, and there is no assurance of the outcome. Coverage, Reimbursement and Pricing Challenges exist that pertain to the coverage and reimbursement status of any products for which regulatory approval is sought. In the United States and foreign markets, sales of any products that receive regulatory approval for commercial sale will depend, in part, on the availability of coverage and the adequacy of reimbursement from third- party payors. Third-party payors include government authorities, such as Medicare and Medicaid, and private entities, such as managed care organizations, private health insurers and other organizations. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the reimbursement rate that the payor will pay for the product. The latter is often informed by entities such as the Institute for Clinical and Economic Review ("ICER") which provides a reimbursement rate based on a multifactorial value assessment. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not include all of the FDA-approved products for a particular indication. Typically patients must "step through," or fail less expensive therapies such as generics in order to be prescribed a branded therapy. Moreover, a third-party payor's decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. For example, the payor's reimbursement payment rate may not be adequate or may require patient co-payments that patients find unacceptably high. Additionally, coverage and reimbursement for products can differ significantly from one payor system to the next. Private payor systems set reimbursement policy in accordance with their particular model. For example, some payor systems mandate value based pricing wherein a particular price point is premised upon achieving a particular goal. These can include an improvement in patients’clinical course (therapeutic effectiveness), or reductions in drug and health care utilization and cost. Thus a third-party payor's decision to cover a particular product does not ensure that other payors will also provide the same level of coverage for the product, or will provide coverage at an adequate reimbursement rate. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. Third-party payors payors require evidence of value that are supplemental to the regulatory mandates of safety and efficacy in order to support a particular price. To obtain coverage and reimbursement for any product that might be approved for sale, there is often a need to conduct expensive pharmacoeconomic studies to demonstrate the medical necessity (based on evidence of disease burden and unmet need) and cost-effectiveness of the therapy. As mentioned, the ICER evidence review mandates such information.These studies will be in addition to the studies required to obtain regulatory approvals. If third- party payors do not consider a product to be cost-effective compared to other available therapies, they may not cover the product after approval as a benefit under their plans or, they may deem a subpopulation of eligible patients based on greater unmet need as eligible for reimbursement. Thus, obtaining and maintaining reimbursement status can be time-consuming and costly.But drug developers accept these requirements as a condition of reimbursement, analogous to their acceptance of the level of evidence needed to obtain regulatory approval. The U.S. and foreign governments regularly consider reform measures that affect health care coverage and costs. For example, the U.S. and particularly state legislatures have implemented cost 31 Table of Contents containment programs that include price controls, restrictions on reimbursement and "first use" of generic products prior to access to branded prescriptions. The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act ("collectively, the ACA") contains provisions such as increased rebates for products sold to Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies' share of sales to federal health care programs. The Centers for Medicare and Medicaid Services ("CMS") may develop new payment and delivery models, such as bundled payment models. For example, the U.S. Department of Health and Human Services ("HHS") moved 41% of Medicare fee-for-service payments to alternative payment models ("APMs") tied to the quality or value of services by the end of 2018. HHS had set a goal of moving 50% of such Medicare payments into these alternative payment models by the end of 2018, but in 2019, this performance goal was discontinued and replaced it with a new developmental goal to increase the percentage of Medicare health care dollars tied to APMs incorporating downside risk, with a target of 40% for fiscal year 2021. These constitute significant challenges,which are analogous to the regulatory hurdles in many aspects and drug developers acknowledge these challenges as the path to providing safe and effective therapies to the patients that require them. European Union Coverage Reimbursement and Pricing In the European Union, pricing and reimbursement requirements can vary widely from country to country. Some countries link market authorization to reimbursement decisions. Others may require the completion of additional studies that assess the cost-effectiveness or comparative effectiveness of novel approved drugs relative to standard of care. These are compiled as health technology assessments ("HTAs"), that constitute a requisite for reimbursement or pricing approval. For example, the European Union provides options for its member states to restrict the range of drug products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. European Union member states may approve a specific price for a drug product or may instead adopt a system of access restrictions that typically target sub populations with high unmet need. Healthcare Laws and Regulations Physicians, other healthcare providers, and third-party payors will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Future arrangements with healthcare professionals, principal investigators, consultants, customers and third-party payors are and will be subject to various federal, state and foreign fraud and abuse laws and other healthcare laws and regulations. These laws and regulations may impact, among other things, healthcare professionals who participate in our clinical research programs, and our proposed sales, marketing, distribution, and education programs. The U.S. federal and state healthcare laws and regulations that may affect our ability to operate include, without limitation, the following: • The federal Anti-Kickback Statute, which prohibits persons from, among other things, knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under federally funded healthcare programs, such as Medicare and Medicaid. The term "remuneration" has been broadly interpreted to include anything of value; • The federal civil and criminal false claims laws, including, without limitation, the federal civil monetary penalties law and the civil False Claims Act (which can be enforced by private citizens through qui tam actions), prohibit individuals or entities from, among other things, knowingly presenting, or causing to be presented, false or fraudulent claims for payment of federal funds, and knowingly making, or causing to be made, a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government; • The federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA") which imposes criminal liability for executing or attempting to execute a scheme to defraud any healthcare benefit program and creates federal criminal laws that prohibit knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services; • HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act ("HITECH") enacted as part of the American Recovery and Reinvestment Act of 2009 and its implementing regulations, which imposes certain obligations, including mandatory contractual terms, on entities subject to the law, such as healthcare providers, health plans, and healthcare clearinghouses and their respective business associates to safeguard the privacy, security and transmission of individually identifiable health information from any unauthorized use or disclosures; • The federal transparency requirements under the Physician Payments Sunshine Act, created under the ACA, which requires certain manufacturers of drugs, devices, biologics and medical supplies reimbursed under Medicare, Medicaid, and other programs such as CHIP to report to HHS information related to payments and other transfers of value provided to physicians and 32 Table of Contents teaching hospitals and physician ownership and investment interests; and • Analogous state laws and regulations, such as state anti- kickback and false claims laws, that impose similar restrictions and may apply to items or services reimbursed by non-governmental third- party payors, including private insurers; state laws that require pharmaceutical companies to implement compliance programs, comply with the pharmaceutical industry's voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, or to track and report gifts, compensation and other remuneration provided to physicians and other health care providers; and state health information privacy and data breach notification laws, which govern the collection, use, disclosure, and protection of health-related and other personal information, many of which differ from each other in significant ways and some of which are not pre-empted by HIPAA, thus complicating compliance efforts. We will be required to spend substantial time and money to ensure that our business arrangements with third parties comply with applicable healthcare laws and regulations. Healthcare reform legislation has strengthened these federal and state healthcare laws. For example, the ACA amended the intent requirement of the federal Anti-Kickback Statute and criminal healthcare fraud statutes to clarify that liability under these statutes does not require a person or entity to have actual knowledge of the statutes or a specific intent to violate them. Moreover, the ACA provides that the government may assert that a claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under one or more of such laws. Violations of these laws can subject us to criminal, civil and administrative sanctions including monetary penalties, damages, fines, disgorgement, individual imprisonment, and exclusion from participation in government funded healthcare programs, such as Medicare and Medicaid, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, and reputational harm, we may be required to curtail or restructure our operations. Moreover, we expect that there will continue to be federal and state laws and regulations, proposed and implemented, that could impact our future operations and business. Healthcare Reform The legislative landscape in the United States continues to evolve. There have been a number of legislative and regulatory changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs. In March 2010, the ACA was enacted, which includes measures that have significantly changed health care financing by both governmental and private insurers. Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states, without specifically ruling on the ACA’s constitutionality. The provisions of the ACA of importance to the pharmaceutical and biotechnology industry are, among others, the following: • an annual, non-deductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, which is apportioned among these entities according to their market share in certain government healthcare programs; • a new Medicare Part D coverage gap discount program, in which manufacturers must now agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; • new requirements to report certain financial arrangements with physicians and certain others, including reporting “transfers of value” made or distributed to prescribers and other healthcare providers and reporting investment interests; • an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively; • a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; • extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; • expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to certain individuals with income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability; • expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; • a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct 33 Table of Contents comparative clinical effectiveness research, along with funding for such research; and • establishment of the Center for Medicare Innovation at the Centers for Medicare and Medicaid Services ("CMS"), to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending. Some of the provisions of the ACA have yet to be implemented, and there have been judicial and Congressional challenges to certain aspects of the ACA. In January of 2021, an Executive Order entitled “Executive Order on Strengthening Medicaid and the Affordable Care Act” repealed two previous Executive Orders delaying the implementation of certain provisions of the ACA. Concurrently, Congress has considered legislation that amend all or part of the ACA. In addition, other federal health reform measures have been proposed and adopted in the United States since the ACA was enacted. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year pursuant to the Budget Control Act of 2011 (known as Medicare sequestration) and subsequent extensions, which began in 2013 and will remain in effect through 2030 (with the exception of a temporary suspension from May 1, 2020 through March 31, 2022, with a subsequent one quarter phase-in of 1%) unless additional Congressional action is taken. Further, the American Taxpayer Relief Act of 2012 reduced Medicare payments to several providers and increased the statute of limitations period for the government to recover overpayments from providers from three to five years. The Medicare Access and CHIP Reauthorization Act of 2015 also introduced a quality payment program under which certain individual Medicare providers will be subject to certain incentives or penalties based on new program quality standards. Payment adjustments for the Medicare quality payment program were scheduled to begin in 2019. At this time, it is unclear how the introduction of the quality payment program will impact overall physician reimbursement under the Medicare program. Further, there have been several recent Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. At the federal level, the costs of prescription pharmaceuticals in the United States has also been the subject of considerable discussion. The previous administration released a "Blueprint" to lower drug prices and reduce out-of-pocket costs of drugs. HHS solicited feedback on some of these measures and, concurrently, implemented others under its existing authority. President Biden continues to push for reforms that would address the high cost of drugs. In response to an Executive Order from President Biden, the Secretary of HHS recently issued a comprehensive plan for addressing high drug prices that describes a number of legislative approaches and identifies administrative tools to address the high cost of drugs. And Democrats recently included drug pricing reform provisions reflecting elements of the plan in a broader spending package in late 2021—such as capping Medicare Part D patients’ out-of-pocket costs, establishing penalties for drug prices that increase faster than inflation in Medicare, and authorizing the federal government to negotiate prices on certain select, high-cost drugs under Medicare Parts B and D. While a number of these and other proposed measures would require authorization through additional legislation to become effective, Congress has indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. In August 2022, Congress passed the Inflation Reduction Act of 2022, which included, among other things, a provision allowing Medicare to negotiate drug prices directly with pharmaceutical manufacturers. At the state level, legislatures 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, regional healthcare authorities 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 healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. The Foreign Corrupt Practices Act The Foreign Corrupt Practices Act (the "FCPA") prohibits any U.S. individual or business from paying, offering, or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. Activities that violate the FCPA, even if they occur wholly outside the United States, can result in criminal and civil fines, imprisonment, disgorgement, oversight, and debarment from government contracts. 34 Table of Contents Environmental, Social, Governance, and Human Capital Governance and Leadership Our commitment to integrating sustainability across our organization begins with our Board of Directors. The Nominating and Governance Committee of the Board has oversight of strategy and risk management related to Environmental, Social and Governance (“ESG”). Applying NYSE’s listing standards for independence, six of our eight directors are independent. At the management level, we have implemented a cross- functional Sustainability Working Group, which is set to meet on a regular basis and report to the Board of Directors periodically. We also maintain a Chief Talent & Sustainability Officer position to work closely with the working group and coordinate efforts related to the advancement of ESG capabilities across the organization. Business Ethics We are committed to creating an environment where we are able to excel in our business while maintaining the highest standards of conduct and ethics. Our Code of Business Conduct and Ethics (the “Code of Conduct”) will reflect the business practices and principles of behavior that support this commitment, including our policies on bribery, corruption, conflicts of interest and our whistleblower program. We expect every director, officer, and employee to read, understand, and comply with the Code of Conduct and its application to the performance of his or her business responsibilities. We encourage employees to come to us with observations and complaints, ensuring we understand the severity and frequency of an event in order to escalate and assess accordingly. Our Chief Compliance Officer strives to ensure accountability, objectivity, and compliance with our Code of Conduct. If a complaint is financial in nature, the Audit Committee Chair is notified concurrently, which triggers an investigation, action, and report. All incidents are reported up to the Board of Directors on a quarterly basis. Environmental Commitment We are committed to protecting the environment and attempt to mitigate any negative impact of our operations. We monitor resource use, improve efficiency, and at the same time reduce our emissions and waste. In order to reduce the overall impact of our product on the environment, we have taken steps to enhance the sustainability of our manufacturing processes for our drug substances. In collaboration with our contract research organization partners, we apply various green chemistry methodologies to our commercial and development pipeline. We have especially focused on using biocatalysis, a technology that makes use of enzymes instead of chemicals to accomplish specific chemical reactions used to construct organic small molecules such as Active Pharmaceutical Ingredients. We have also initiated work in removing hazardous organic solvents from certain reactions and replacing them with water. This green technology relies on the use of micelles to enable such reactions to occur in water where they would normally not occur due in part to the very poor solubility of most organic compounds in water. These greener processes not only create less waste, but the waste that is produced is much less hazardous, therefore reducing the environmental impact of the manufacturing process. Social Responsibility For third-party vendor selection and oversight, we have adopted standard operating procedures that apply to employees and subcontractors who on our behalf, oversee and conduct research regulated by the FDA. We retain ultimate authority and responsibility for the conduct of regulated research, manufacturing, and testing and we must ensure that contracted services are conducted in accordance with Good Practice Guidelines and all applicable regulations. Human Capital Management We foster and encourage a workplace environment that holds possibilities for everyone, with a commitment to respect and acceptance without biases. Development and continuous feedback are priorities for our organization, which was comprised of 202 employees as of January 1, 2023. We believe each person is critical to our success and we invest in our people by supporting continuous training programs and courses. We encourage each employee to engage with their manager in developmental discussions designed to focus on feedback rather than a rating. An important part of our talent recruitment is our robust paid internship program for high school, college and graduate-level students. This program offers opportunities to students in the community and develops a roadmap for ‘entry-level’ candidates. We evaluate the success of our recruitment program through metrics such as time to hire, offer acceptance rate, turnover rate and business results. We strive to provide an inclusive workplace to foster growth and innovation. Biohaven is committed to gender diversity in the workforce, as evidenced by a workforce that is approximately 60% female and includes a robust group of female leaders in the scientific and associated fields. Biohaven engages in forward-thinking people policies to allow for our employees to thrive in our workforce. Regular attendance at an office is only required of our lab professionals, allowing over 50% of 35 Table of Contents our workforce to work remotely full-time. Our vacation policy is unlimited, and is aimed at giving employees the ability to achieve work/life balance in a way that is bespoke to their circumstances. When the COVID-19 pandemic hit in early 2020, we quickly established both an office-based and field-based response to protect our employees. We first and foremost encouraged all office-based employees to work from home and provided support for fully remote work. In our offices, we follow health and safety protocols by providing mandatory masks for anyone entering the building, foot-dispensing hand sanitizer stations, and disinfecting wipes at each workstation. We purchased high efficiency air filters to ensure air is not recirculated in the facilities. We offer antibody testing and encourage employees to be tested for COVID-19 frequently.

Risk Factors In connection with any investment decision with respect to our securities, you should carefully consider the risks described below, as well as general economic and business risks and the other information in this Annual Report on Form 10-K and in our other filings with the SEC. The occurrence of any of the events or circumstances described below or other adverse events could have a material adverse effect on our business, results of operations and financial condition and could cause the trading price of our common shares to decline. Additional risks or uncertainties not presently known to us or that we currently deem immaterial may also harm our business. SUMMARY An investment in our common shares is subject to a number of risks, including risks related to our product candidates, risks related to our business and risks related to our common shares. The following list of risk factors is not exhaustive. Please read the information in the section captioned “Risk Factors” for a more thorough description of these and other risks. Risks Related to Our Financial Position and Need for Additional Capital • We have a limited operating history, have incurred significant operating losses since inception and anticipate that we will continue to incur substantial operating losses for the foreseeable future. • Deterioration in general economic conditions in the United States and globally, including the effect of prolonged periods of inflation on our suppliers, third-party service providers and potential partners, may have a negative impact on our business and results of operations. • An inability to raise capital when needed or on terms favorable to us could force us to curtail our planned operations and growth strategy. • Credit risk with respect to our investments or the financial institutions at which we deposit funds could adversely affect us. Risks Related to the Development of Our Product Candidates • We depend entirely on the success of a limited number of product candidates. • Clinical trials are very expensive, time consuming and difficult to design and implement, involve uncertain outcomes and may not be predictive of results of future trials. • Regulatory approval processes in the U.S. and foreign jurisdictions are lengthy, time consuming and unpredictable. • Our product candidates may fail to demonstrate safety and efficacy in clinical trials, or may cause serious adverse or unacceptable side effects. • We may become exposed to costly and damaging liability claims, which may not be covered by insurance. Risks Related to Commercialization of Our Product Candidates • We have never commercialized a product candidate and may lack the necessary expertise, personnel and resources to successfully commercialize any product candidate that may receive regulatory approval. • We operate in a highly competitive and rapidly changing industry. • Failure to obtain or maintain adequate coverage and reimbursement for our approved product candidates could limit our ability to market those products and decrease our ability to generate revenue. • Our product candidates, if approved, will be subject to ongoing regulatory oversight. • Our approved product candidates may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success. Risks Related to Our Dependence on Third Parties • We rely on third parties to conduct our preclinical studies and clinical trials and to supply, manufacture and distribute clinical drug supplies for our product candidates, which may expose our business to risks. • We may not establish or maintain collaborations with third parties to develop or commercialize product candidates. Risks Related to Regulatory Compliance • Enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and may affect the prices we may set. • Our business operations and relationships with investigators, health care professionals, consultants, third-party payors and customers are subject to federal and state healthcare and other laws. • We may not obtain or maintain orphan drug designation or exclusivity for our product candidates. Risks Related to Our Intellectual Property • We could lose market exclusivity earlier than expected. 37 Table of Contents • • • • If we were unable to obtain licenses from third parties on commercially reasonable terms or lose our rights to licensed intellectual property, we may not be able to continue developing or commercializing our product candidates. Patent terms may not provide exclusivity for our product candidates for an adequate amount of time to realize sufficient commercial benefits. Third parties may seek to invalidate our patents. Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a negative impact on the success of our business. Risks Related to Our Business Operations, Employee Matters and Managing Growth • Our future growth and ability to compete depend on, among other things, retaining key personnel and recruiting additional qualified personnel and on our ability to penetrate foreign markets. • Laws and regulations governing our international operations may preclude us from developing, manufacturing and selling certain product candidates and products outside of the United States and require us to develop and implement costly compliance programs. • We may encounter difficulties in managing our growth, which could disrupt our operations. • Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs and vendors may engage in improper activities. Risks Related to Ownership of Our Common Shares • • • • Substantially all of our total outstanding shares may be sold freely into the market. This could cause the market price of our common shares to drop significantly, even if our business is doing well. Because we do not expect to pay dividends on our common shares in the foreseeable future, capital appreciation, if any, would be your sole source of gain. The trading price of our common shares may be volatile and may fluctuate. If we are or become a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S. holders. • Our historical financial results as a part of Former Parent may not be representative of our results as a separate, stand-alone company. 38 Table of Contents Risks Related to Our Financial Position and Need for Additional Capital We have a limited operating history and have never generated any product revenues, which may make it difficult to evaluate the success of our business to date and to assess our future viability. We were incorporated on May 2, 2022 as a direct, wholly-owned subsidiary of Former Parent. Our operations to date have been largely focused on organizing and staffing, raising capital and in-licensing the rights to, and advancing the development of, our product candidates, including conducting preclinical studies and clinical trials. We have not yet demonstrated an ability to obtain marketing approvals for any product candidates, manufacture products on a commercial scale, or arrange for a third party to do so on our behalf, or conduct sales and marketing activities necessary for successful commercialization. Consequently, predictions about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully developing and commercializing products. We expect our financial condition and operating results to continue to fluctuate from quarter to quarter and year to year due to a variety of factors, many of which are beyond our control. We will need to eventually transition from a company with a research and development focus to a company capable of undertaking commercial activities. We may encounter unforeseen expenses, difficulties, complications and delays, and may not be successful in such a transition. Deterioration in general economic conditions in the United States and globally, including the effect of prolonged periods of inflation on our suppliers, third-party service providers and potential partners, may have a negative impact on our business and results of operations. Our business and results of operations could be adversely affected by changes in national or global economic conditions. These conditions include, but are not limited to, high levels of, and rising, inflation, high and rising interest rates, any volatility in the capital markets, energy availability and costs, the negative impacts from pandemics and public health crises (including any lingering or recurring adverse impacts from COVID-19), negative impacts resulting from the military conflict between Russia and the Ukraine, and the effects of governmental initiatives to manage economic conditions. Impacts of such conditions could be passed on to our business in the form of higher costs for labor and materials, higher investigator fees, possible reductions in pharmaceutical industry-wide spending on research and development and acquisitions and higher costs of capital. We have incurred significant operating losses since our inception as a business of Former Parent and anticipate that we will continue to incur substantial operating losses for the foreseeable future and may never achieve or maintain profitability. Since our inception as a business of Former Parent, we have incurred significant operating losses. Our net loss was $570.3 million, $213.8 million and $118.7 million for the years ended December 31, 2022, 2021 and 2020, respectively. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future. None of our product candidates has been approved for marketing in the United States, or in any other jurisdiction, and may never receive such approval. It could be several years, if ever, before we have a commercialized product that generates significant revenues. As a result, we are uncertain when or if we will achieve profitability and, if so, whether we will be able to sustain it. The net losses we incur may fluctuate significantly from quarter to quarter and year to year. We anticipate that our expenses will increase substantially as we: • initiate, continue, or complete planned or ongoing clinical trials of our current product candidates, including related support activities; • continue to initiate and progress other supporting studies required for regulatory approval of our product candidates, including long-term safety studies, drug-drug interaction studies, preclinical toxicology and carcinogenicity studies; • make required milestone and royalty payments under the license agreements by which we acquired some of the rights to our product candidates; • initiate preclinical studies and clinical trials for any additional indications for our current product candidates and any future product candidates that we may pursue; • continue to build our portfolio of product candidates through the acquisition or in-license of additional product candidates or technologies; • continue to develop, maintain, expand and protect our intellectual property portfolio; • pursue regulatory approvals for our current and future product candidates that successfully complete clinical trials; • ultimately establish a sales, marketing and distribution infrastructure to commercialize any product candidate for which we may obtain marketing approval; • hire additional clinical, medical, commercial, and development personnel; and • incur additional legal, accounting and other expenses in operating as a public company. 39 Table of Contents To become and remain profitable, we must develop and eventually commercialize one or more product candidates with significant market potential. This will require us to be successful in a range of challenging activities, including completing clinical trials of our product candidates, developing commercial scale manufacturing processes, obtaining marketing approval, manufacturing, marketing and selling any current and future product candidates for which we may obtain marketing approval, and satisfying any post-marketing requirements. We are only in the preliminary stages of most of these activities and, in some cases, have not yet commenced certain of these activities. We may never succeed in any or all of these activities and, even if we do, we may never generate sufficient revenue to achieve profitability. Because of the numerous risks and uncertainties associated with product development, we are unable to accurately predict the timing or amount of expenses or when, or if, we will obtain marketing approval to commercialize any of our product candidates. If we are required by the FDA or other regulatory authorities such as the EMA to perform studies and trials in addition to those currently expected, or if there are any delays in the development, or in the completion of any planned or future preclinical studies or clinical trials of our current or future product candidates, our expenses could increase and profitability could be further delayed. 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 could decrease the value of our company and could impair our ability to raise capital, maintain our research and development efforts, expand our business or continue our operations. A decline in the value of our company also could cause you to lose all or part of your investment. We will need substantial additional funding to pursue our business objectives. If we are unable to raise capital when needed or on terms favorable to us, we could be forced to curtail our planned operations and the pursuit of our growth strategy. Identifying potential product candidates and conducting preclinical studies 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 regulatory approval and achieve product sales. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue to develop our product candidates. Our expenses could increase beyond our current expectations if the FDA requires us to perform clinical trials and other studies in addition to those that we currently anticipate. For example, for our troriluzole clinical program, we conducted a Phase 2/3 clinical trial in SCA incorporating feedback from the FDA in response to discussion that we had with the FDA regarding proposed modifications to the scale for assessment and rating of Ataxia, the primary endpoint in the trial. The clinical trial failed to meet the primary endpoints, however SCA3 patients experienced a clinically meaningful improvement in ataxia symptoms on troriluzole treatment. Given these findings and the debilitating nature of SCA, we intend to interact with the FDA and or EMA in the first half of 2023. If the FDA requires us to conduct additional clinical trials of troriluzole, or any of our other product candidates, we would incur substantial additional, unanticipated expenses in order to obtain regulatory approval of those product candidates. In addition, our product candidates, if approved, may not achieve commercial success. Our revenue, if any, will be derived from sales of products that we do not expect to be commercially available for a number of years, if at all. Additionally, if we obtain marketing approval for our product candidates, we expect to incur significant expenses related to manufacturing, marketing, sales and distribution and, with respect to certain of our product candidates, the payment of milestone and royalty fees. Furthermore, we expect to incur additional costs associated with operating as a public company. As of December 31, 2022, we had cash, cash equivalents and marketable securities of $465.3 million, excluding restricted cash of $37.7 million. We expect that our existing cash, cash equivalents and marketable securities will be sufficient to fund our planned operating expenses, financial commitments and other cash requirements for at least 12 months from the date of filing of this report. This estimate is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we expect. Changes may occur beyond our control that would cause us to consume our available capital before that time, including changes in and progress of our development activities and changes in regulation. Our future capital requirements will depend on many factors, including: • the scope, progress, results and costs of our ongoing and planned preclinical studies and clinical trials for our product candidates; • the timing and amount of milestone and royalty payments we are required to make under our license agreements; • the extent to which we in-license or acquire other product candidates and technologies; • the number and development requirements of other product candidates that we may pursue, and other indications for our current product candidates that we may pursue; • the costs, timing and outcome of regulatory review of our product candidates; • including drug the costs and timing of future commercialization activities, 40 Table of Contents manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; • the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; • our ability to establish strategic collaborations for the development or commercialization of some of our product candidates; and • 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 brought by third parties against us. We may require additional capital to complete our planned clinical development programs for our current product candidates to seek regulatory approval. If we receive regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, sales, marketing and distribution. Any additional capital-raising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our current and future product candidates, if approved. In addition, we cannot guarantee that future financing will be available on a timely basis, in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our shareholders and the issuance of additional securities by us, whether equity or debt, or the market perception that such issuances are likely to occur, could cause the market price of our common shares to decline. As a result, we may not be able to access the capital markets as frequently as comparable U.S. companies. If we are unable to obtain funding on a timely basis on acceptable terms, we may be required to significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any product candidates, if approved, or be unable to expand our operations or otherwise capitalize on our business opportunities, as desired. Raising additional capital may cause dilution to our shareholders, restrict our operations or require us to relinquish rights to our intellectual property or future revenue streams. Until such time as we can generate substantial product revenue, if ever, we expect to finance our operations through a combination of equity offerings, debt financings and license and development agreements in connection with any future collaborations. We do not have any committed external source of funds. In the event we seek additional funds, we may raise additional capital through the sale of equity or convertible debt securities. In such an event, our existing shareholders may experience substantial dilution, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of the holders of our common shares. Debt financing, if available, could result in increased fixed payment obligations and may involve agreements that include restrictive covenants, such as limitations on our ability to incur additional debt, make capital expenditures, acquire, sell or license intellectual property rights or declare dividends, and other operating restrictions that could hurt our ability to conduct our business. Further, if we raise additional capital through collaborations, strategic alliances, or marketing, distribution, licensing or funding arrangements with third parties, we may have to relinquish valuable rights to our intellectual property future revenue streams, research programs or product candidates, or grant licenses on terms that may not be favorable to us. Credit risk with respect to our investments or the financial institutions at which we deposit funds could adversely affect us. Financial instruments that expose us to concentrations of credit risk consist of cash, cash equivalents, and short-term debt securities. Market conditions and changing circumstances, many of which are beyond our control, could reduce the value of our investments or impair our ability to access our existing cash, cash equivalents or other investments. For example, rising interest rates could negatively impact the value of investments that are not held to maturity. We maintain cash deposits that are in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limit in FDIC- insured financial institutions. If any financial institution with which we have a banking relationship were to be placed into receivership or become insolvent in the future, we may be unable to access, temporarily or over a longer-term, or we may lose, a portion of our funds on deposit with that institution. For example, on March 10, 2023 and March 12, 2023, Silicon Valley Bank and Signature Bank, respectively, were placed into receivership with the FDIC, which resulted in all funds held at those banks being temporarily inaccessible by their customers. While we have no relationship with the financial institutions above, any delay in our ability to access our cash, cash equivalents and investments, or the loss of some or all of such funds, could result in us not being able to pay our employees, vendors or others on a timely basis, or at all, and could hinder us from being able to enter into commercial arrangements that could be advantageous to us. Conversely, if any of our counterparties are impacted by any banking failures, that could impact their ability to transact with us. Any of the foregoing could adversely impact, possibly materially, our business and operations. 41 Table of Contents Risks Related to the Development of Our Product Candidates • the prevalence and severity of adverse events experienced Our current business depends entirely on the success of a limited number of product candidates, which are in clinical development. If we do not obtain or are delayed in obtaining regulatory approval for and successfully commercialize one or more of our product candidates, our business, financial condition and results of operations could be materially impacted and we may never become profitable. Biotechnology product development is a highly speculative undertaking and involves a substantial degree of risk. We do not have any products that have received regulatory approval, and therefore we have never generated any revenue from product sales, and we may never be able to develop product candidates that receive regulatory approval or are successfully commercialized after regulatory approval is received. Consequently, the revenue-generating potential of our business is unproven and uncertain. We expect that a substantial portion of our efforts and expenses over the next few years will be devoted to the development of our product candidates; specifically, completion of our Phase 3 clinical trials of troriluzole in OCD, execution of clinical trials for BHV-7000, including late-stage studies in epilepsy and mood disorders, completion of a Phase 2/3 clinical trial of troriluzole in glioblastoma, and completion of a Phase 3 clinical trial of BHV-2000 in SMA. As a result, our business currently depends heavily on the successful development, regulatory approval and, if approved, commercialization of these product candidates. We cannot be certain that we will be able to submit a new drug application (“NDA”), biologics license application (“BLA”) or comparable applications in other jurisdictions for any of our product candidates within the timeframes we expect, or that any NDA, BLA or similar application we submit will be accepted by the FDA or comparable foreign regulators for filing in a timely manner or at all. The research, testing, manufacturing, safety, efficacy, labeling, approval, sale, marketing and distribution of our product candidates are, and will remain, subject to comprehensive regulation by the FDA and similar foreign regulatory authorities. The success of our product candidates will depend on various factors, including: • completing clinical trials that demonstrate our product candidates’ efficacy and safety; • authorities; receiving marketing approvals from applicable regulatory • completing any post-marketing studies required by applicable regulatory authorities; • establishing commercial manufacturing capabilities; • operations; launching commercial sales, marketing and distribution with our product candidates; • acceptance of our product candidates by patients, the medical community and third-party payors; • a continued acceptable safety profile following approval; • obtaining and maintaining healthcare coverage and adequate reimbursement for our product candidates; • competing effectively with other therapies, including with respect to the sales and marketing of our product candidates, if approved; and • qualifying for, maintaining, enforcing and defending our intellectual property rights and claims. Many of these factors are beyond our control, including the time needed to adequately complete clinical testing, the regulatory submission process, potential threats to our intellectual property rights and changes in the competitive landscape. Our failure to achieve one or more of these factors in a timely manner or at all could materially harm our business, financial condition and results of operations. Clinical trials are very expensive, time-consuming and difficult to design and implement and involve uncertain outcomes. Furthermore, results of earlier preclinical studies and clinical trials may not be predictive of results of future preclinical studies or clinical trials. Clinical testing is expensive and can take many years to complete, and delay or failure can occur at any time during the clinical trial process. For example, in September 2021, we reported negative topline results from our Phase 3 clinical trial evaluating verdiperstat compared to placebo for the treatment of participants with MSA. In September 2022, we reported negative topline results from the Phase 2/3 HEALEY ALS Platform trial evaluating verdiperstat compared to placebo for the treatment of participants with ALS. In addition, the results generated to date in preclinical studies or clinical trials for our product candidates do not ensure that later preclinical studies or clinical trials will demonstrate similar results. Further, we have limited clinical data for many of our product candidates. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical and earlier stage clinical trials. In later- stage clinical trials, we will likely be subject to more rigorous statistical analyses than in completed earlier stage clinical trials. In some instances, there can be significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes in clinical trial procedures set forth in protocols, differences in the size 42 Table of Contents and type of the patient populations, adherence to the dosing regimen, and the rate of dropout among clinical trial participants. If we fail to produce positive results in our planned preclinical studies or clinical trials of any of our product candidates, the development timeline and regulatory approval and commercialization prospects for our product candidates, and, correspondingly, our business and financial prospects, would be materially adversely affected. Interim topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data. From time to time, we may publish interim topline or preliminary data from our clinical trials. Interim data from clinical trials that we may complete 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. Preliminary or topline 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, interim and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our reputation and business prospects. We have limited experience in drug discovery and drug development. Because we in-licensed some of our investigational agents from other companies, including BHV-2000 from BMS and BHV-5000 and verdiperstat from AstraZeneca, we were not involved in and had no control over the preclinical and clinical development of these product candidates prior to entering into these in-license agreements. In addition, we are relying on the other companies from which we licensed our investigational agents to have conducted such research and development in accordance with the applicable protocol, legal, regulatory and scientific standards, accurately reported the results of all clinical trials conducted prior to our acquisition of the applicable product candidate, and correctly collected and interpreted the data from these studies and trials. To the extent any of these has not occurred, our expected development time and costs may be increased, which could adversely affect our prospects for marketing approval of, and receiving any future revenue from, these product candidates. Clinical trials may be delayed, suspended or terminated for many reasons, which will increase our expenses and delay the time it takes to develop our product candidates. We may experience delays in our ongoing or future preclinical studies or clinical trials, and we do not know whether future preclinical studies or clinical trials need to be redesigned, enroll an adequate number of patients on time or begin or be completed on schedule, if at all. The commencement and completion of clinical trials for our clinical product candidates may be delayed, suspended or terminated as a result of many factors, including: • the FDA or other regulators disagreeing as to the design, protocol or implementation of our clinical trials; • the delay or refusal of regulators (including the FDA) or institutional review boards (“IRBs”) to authorize us to commence a clinical trial; • regulators (including the FDA), IRBs, ethics committees of the institutions at which trials are being conducted or the data safety monitoring board for such trials requiring that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements (including the FDA’s current Good Clinical Practice (“GCP”) regulations) or our clinical protocols, safety concerns, adverse side effects, or lack of adequate funding to continue the clinical trial, among others; • changes in regulatory requirements, policies and guidelines; • delays or failure to reach agreement on acceptable terms with prospective clinical research organization (“CROs”) and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; delays in patient enrollment and variability in the number and types of patients available for clinical trials; • the inability to enroll a sufficient number of patients in trials, particularly in orphan indications, to observe statistically significant treatment effects in the trial; • having clinical sites deviate from the trial protocol or dropping out of a trial; • negative or inconclusive results from ongoing preclinical studies or clinical trials, which may require us to conduct additional preclinical studies or clinical trials or to abandon projects that we expect to be promising; • safety or tolerability concerns (including due to reports from testing of similar therapies) that could cause us to suspend or terminate a trial if we find that the participants are being exposed to unacceptable health risks; 43 Table of Contents • regulators or IRBs requiring that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or safety concerns, among others; • lower than anticipated retention rates of patients and volunteers in clinical trials; • our CROs or clinical trial sites failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all, deviating from the protocol or dropping out of a trial; • delays relating to adding new clinical trial sites; • difficulty in maintaining contact with patients after treatment, resulting in incomplete data; • delays in establishing the appropriate dosage levels; • the quality or stability of the product candidate falling below acceptable standards; • the inability to produce or obtain sufficient quantities of the product candidate to commence or complete clinical trials; and • exceeding budgeted costs due to difficulty in accurately predicting costs associated with clinical trials. Any delays in completing our clinical trials will increase our costs, slow down our product candidate development and approval process and jeopardize our ability to commence product sales and generate revenue from product sales. Any of these occurrences may significantly harm our business, financial condition and prospects. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. The regulatory approval processes of the FDA and comparable foreign regulatory agencies are lengthy, time- consuming and unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be materially harmed. Neither we nor any future collaborator is permitted to market any of our product candidates in the United States or abroad until we receive regulatory approval of an NDA or BLA from the FDA or approval from the EMA, NMPA or other applicable foreign regulatory agency. The time required to obtain approval by the FDA is unpredictable but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including those beyond our control, such as the substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval is generally uncertain, may change during the course of a product candidate’s clinical development and may vary among jurisdictions. Prior to obtaining approval to commercialize a product candidate in any jurisdiction, we must demonstrate to the satisfaction of the FDA, EMA, NMPA or any comparable foreign regulatory agency, that such product candidates are safe and effective for their intended uses. The FDA, EMA, NMPA or any comparable foreign regulatory agency can delay, limit or deny approval of our product candidates or require us to conduct additional preclinical or clinical testing or abandon a program for many reasons, including: • the FDA, EMA, NMPA or the applicable foreign regulatory agency’s disagreement with the number, design, conduct or implementation of our preclinical studies and clinical trials; • negative or ambiguous results from our clinical trials or results that may not meet the level of statistical significance required by the FDA, EMA, NMPA or any comparable foreign regulatory agency for approval; • serious and unexpected drug-related side effects experienced by participants in our clinical trials or by individuals using drugs similar to our product candidates; • our inability to demonstrate to the satisfaction of the FDA, EMA, NMPA or the applicable foreign regulatory agency that our product candidates are safe and effective for their proposed indications, or that the clinical and other benefits of our product candidates outweigh any safety or other perceived risks; • the FDA’s, EMA’s, NMPA’s or the applicable foreign regulatory agency’s disagreement with the interpretation of data from preclinical studies or clinical trials; • actions by the CROs that we retain to conduct our preclinical studies and clinical trials, which are outside of our control and that materially adversely impact our preclinical studies and clinical trials; • the FDA’s, EMA’s, NMPA’s or the applicable foreign regulatory agency’s disagreement regarding the formulation, labeling or the specifications of our product candidates; • the FDA’s, EMA’s, NMPA’s or the applicable foreign regulatory agency’s failure to approve the manufacturing processes or facilities of third-party manufacturers with which we contract; and • the potential for approval policies or regulations of the FDA, EMA, NMPA or the applicable foreign regulatory agencies to significantly change in a manner rendering our clinical data insufficient for approval. For example, with respect to our randomized, controlled clinical trial of troriluzole for the treatment of SCA, we undertook discussions with the FDA regarding the acceptability of the primary endpoint and necessary 44 Table of Contents secondary endpoints, including our proposal to use a modified SARA scale. In our first Phase 2/3 clinical trial, the FDA stated that while certain items measured by the SARA scale appeared capable of reflecting a clinically meaningful benefit for patients depending on how the scoring of those items is defined, the use of the SARA scale was not appropriate as a primary endpoint in the trial. Based on our post- hoc analyses of data from the open-label extension phase of the trial, we proposed modifications to the SARA scale that we believe may address some of these shortcomings. Based on feedback received from the FDA, we incorporated trial design modifications that include utilization of a modified SARA scale. However, notwithstanding the feedback that we have received from the FDA, there remains substantial risk that the FDA or any foreign regulatory agency may nevertheless conclude that results obtained using the modified SARA scale would not be an adequate basis for approval. In addition, in our Phase 3 clinical trial evaluating the efficacy and safety of troriluzole in adult patients with SCA, the primary endpoint, change from baseline to week 48 on the modified SARA scale, did not reach statistical significance in the overall SCA population as there was less than expected disease progression over the course of the study. Post-hoc analysis of efficacy measures by genotype suggests a treatment effect in patients with the SCA Type 3 ("SCA3") genotype. There is substantial risk that the FDA, EMA, NMPA or the applicable foreign regulatory agency may disagree with the interpretation of our data, and there can be no assurance that any such regulatory agency will find the data sufficient to support approval, or that we will not be required to conduct additional testing on the safety and efficacy of troriluzole. We intend to interact with the FDA and/or EMA in the first half of 2023 but have not yet decided on the format of such an interaction. We could seek advice through various formal or informal interactions with regulatory agencies or we could choose to submit an NDA if we believe that is warranted from the results of our ongoing post-hoc analyses. We generally plan to seek regulatory approval to commercialize our product candidates in the United States, the European Union and other key global markets, which requires compliance with numerous and varying regulatory requirements of such other countries regarding safety, efficacy, chemistry, manufacturing and controls, clinical trials, commercial sales, pricing and distribution of our product candidates. Even if we are successful in obtaining approval in one jurisdiction, we cannot ensure that we will obtain approval in any other jurisdiction. Failure to obtain approval in one jurisdiction may negatively impact our ability to obtain approval elsewhere. If we fail to obtain approval in any jurisdiction, the geographic market for our product candidates could be limited. Moreover, even if we were to obtain approval to market any product candidate we develop, 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 for our product candidates. Our product candidates may fail to demonstrate safety and efficacy in clinical trials, or may cause serious adverse or unacceptable side effects that could prevent or delay regulatory approval and commercialization, limit the commercial profile of an approved label, increase our costs, necessitate the abandonment or limitation of the development of some of our product candidates or result in significant negative consequences following marketing approval, if any. Before obtaining regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that our product candidates are both safe and effective for use in each target indication, and failures can occur at any stage of testing. Clinical trials often fail to demonstrate efficacy or safety of the product candidate studied for the target indication. For example, in September 2021 we reported negative topline results from a Phase 3 clinical trial to evaluate the efficacy and safety of verdiperstat in participants with MSA. Results of the trial showed that verdiperstat did not statistically differentiate from placebo on the prespecified primary efficacy measure, nor on the key secondary efficacy measures. In September 2022, we reported negative topline results from the Phase 2/3 HEALEY ALS Platform trial evaluating verdiperstat compared to placebo for the treatment of participants with ALS. At this time, we do not have plans to pursue any additional clinical trials evaluating verdiperstat in ALS, and we may evaluate its potential in other disease indications. Moreover, undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label, the limitation of commercial potential or the delay or denial of regulatory approval by the FDA or a foreign regulatory agency. Results of our clinical trials could reveal a high and unacceptable severity and prevalence of side effects or unexpected characteristics. Accordingly, we may need to abandon the development of certain product candidates or limit development to certain uses or sub-populations in which such side effects are less prevalent, less severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in preclinical or early-stage testing have later been found to cause side effects that restricted their use and 45 Table of Contents prevented further development of the compound in the tested indication. • initiation of regulatory investigations and government enforcement actions; Occurrence of serious treatment-related side effects could impede subject recruitment and clinical trial enrollment or the ability of enrolled patients to complete the trial, delay the clinical trial, and prevent receipt of regulatory approval from the FDA and other regulators. They could also adversely affect physician or patient acceptance of our product candidates or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly. If any of our product candidates receives marketing approval and we, or others, later discover that the drug is less effective than previously believed or causes undesirable side effects that were not previously identified, our ability to market the drug could be compromised. Clinical trials of our product candidates by their nature are conducted in carefully defined subsets of patients who have agreed to enter into clinical trials. Consequently, it is possible that our clinical trials may indicate an apparent positive effect of a product candidate that is greater than the actual positive effect, if any, or alternatively fail to identify undesirable side effects. We have monitored the subjects in our studies for certain safety concerns and we have not seen evidence of significant safety concerns in our clinical trials. However, if one or more of our product candidates receives regulatory approval, and we, or others, later discover that they are less effective than previously believed, or cause undesirable side effects that had not previously been identified, a number of potentially significant negative consequences could result, including: • withdrawal or limitation by regulatory authorities of approvals of such product; • seizure of the product by regulatory authorities; • • recall of the product; restrictions on the marketing of the product or the manufacturing process for any component thereof; • requirement by regulatory authorities of additional warnings on the label, such as a “black box” warning or contraindication; • requirement that we implement a REMS or similar program or create a medication guide outlining the risks of such side effects for distribution to patients; • commitment to expensive additional safety studies prior to approval or post-marketing studies required by regulatory authorities of such product; • the product may become less competitive; • initiation of legal action against us to hold us liable for harm caused to patients; and • harm to our reputation and resulting harm to physician or patient acceptance of our products. • Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could significantly harm our business, financial condition, and results of operations. We depend on enrollment of patients in our clinical trials for our product candidates. If we are unable to enroll patients in our clinical trials, our research and development efforts could be adversely affected. Identifying and qualifying patients to participate in clinical trials of our product candidates is critical to our success. If we are unable to enroll a sufficient number of patients in our clinical trials, our timelines for recruiting patients, conducting clinical trials and obtaining regulatory approval of potential products may be delayed. These delays could result in increased costs, delays in advancing our product development, delays in testing the effectiveness of our technology or termination of our clinical trials altogether. We cannot predict how successful we will be at enrolling patients in future clinical trials. Patient enrollment is affected by other factors including: • • trial; the eligibility criteria for the trial in question; the perceived risks and benefits of the product candidate in the • clinicians’ and patients’ perceptions as to the potential advantages of the product candidate being studied in relation to other available therapies, including any new drugs that may be approved for the indications we are investigating or drugs that may be used off-label for these indications; • the size of the patient population required for analysis of the trial’s primary endpoints; • competition for patients for competitive product candidates undergoing clinical trials; • • • the efforts to facilitate timely enrollment in clinical trials; the design of the trial; the patient referral practices of physicians; the ability to monitor patients adequately during and after • treatment; • the risk that patients enrolled in clinical trials will drop out of the trials before completion; 46 Table of Contents • • • the ability to obtain and maintain patient consents; the number of patients with the indication being studied; and the proximity and availability of clinical trial sites for prospective patients. We may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success. We have limited financial and managerial resources. 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. We may become exposed to costly and damaging liability claims, either when testing our product candidates in the clinic or at the commercial stage, and our product liability insurance may not cover all damages from such claims. We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing, and use of pharmaceutical products. The current and future use of product candidates by us in clinical trials, and the sale of any approved products in the future, may expose us to liability claims. These claims might be made by patients that use the product, healthcare providers, pharmaceutical companies, or others selling such products. In addition, we have agreed to indemnify the licensors of the intellectual property related to our product candidates against certain intellectual property infringement claims. Any claims against us, or with respect to which we are obligated to provide indemnification, regardless of their merit, could be difficult and costly to defend or settle, and could compromise the market acceptance of our product candidates or any prospects for commercialization of our product candidates, if approved. Although the clinical trial process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory approval, may exhibit unforeseen side effects. If any of our product candidates were to cause adverse side effects during clinical trials or after approval of the product candidate, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse effects or identify patients who should not use our product candidates. Although we maintain product liability insurance coverage, such insurance may not be adequate to cover all our liabilities. We may need to increase our insurance coverage each time we commence a clinical trial and if we successfully commercialize any product candidate. As the expense of insurance coverage is increasing, 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. If a successful product liability claim or series of claims is brought against us for uninsured liabilities or in excess of insured liabilities, our assets may not be sufficient to cover such claims and our business operations could be impaired. If serious adverse events or other undesirable side effects are identified during the use of our product candidates in investigator-sponsored trials, it may adversely affect our development of such product candidates. Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt nonclinical studies and clinical trials, or could make it more difficult for us to enroll patients in our clinical trials. If serious adverse events or other undesirable side effects or unexpected characteristics of our product candidates are observed in investigator-sponsored trials, further clinical development of such product candidate may be delayed or we may not be able to continue development of such product candidate at all, and the occurrence of these events could have a material adverse effect on our business. Undesirable side effects caused by our product candidates could also result in the delay or denial of regulatory approval by the FDA or other regulatory authorities or in a more restrictive label than we expect. Risks Related to Commercialization of Our Product Candidates We have never commercialized a product candidate and we may lack the necessary expertise, personnel and resources to successfully commercialize any of our products that receive regulatory approval on our own or together with suitable collaborators. We have never commercialized a product candidate. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, acquiring the rights to our product candidates and undertaking preclinical studies and clinical trials of our product candidates. We currently have no sales force, marketing or distribution capabilities. To achieve commercial success of our product candidates, if any are approved, we will have to 47 Table of Contents develop our own sales, marketing and supply capabilities or outsource these activities to a third party. Factors that may affect our ability to commercialize our product candidates on our own include: recruiting and retaining adequate numbers of effective sales and marketing personnel, obtaining access to or persuading adequate numbers of physicians to prescribe our product candidates, and other unforeseen costs associated with creating an independent sales and marketing organization. Developing a sales and marketing organization requires significant investment, is time-consuming and could delay the launch of our product candidates. We may not be able to build an effective sales and marketing organization in the United States, the European Union or other key global markets. If we are unable to build our own distribution and marketing capabilities or to find suitable partners for the commercialization of our product candidates, we may have difficulties generating revenue from such product candidates or be able to achieve or sustain profitability. To the extent that we enter into collaboration agreements with respect to marketing, sales or distribution of any approved product, our product revenue may be lower than if we directly marketed or sold such product. In addition, any revenue we receive will depend in whole or in part upon the efforts of these third-party collaborators, which may not be successful and are generally not within our control. If we are unable to enter into these arrangements on acceptable terms or at all, we may not be able to successfully commercialize any approved products. We operate in a highly competitive and rapidly changing industry. Failure to compete successfully could adversely affect our business, financial condition and results of operations. Biopharmaceutical product development is highly competitive and subject to rapid and significant technological advancements. Our success is highly dependent upon our ability to in-license, acquire, develop and obtain regulatory approval for new and innovative products on a cost-effective basis and to market them successfully. In doing so, we face and will continue to face intense competition from a variety of businesses, including large, fully integrated, well-established pharmaceutical companies who already possess a large share of the market, specialty pharmaceutical and biopharmaceutical companies, academic institutions, government agencies and other private and public research institutions in the United States, the European Union and other jurisdictions. With respect to troriluzole, which we are currently developing for the treatment of ataxias and other neurologic disorders, with SCA as our initial indication, there are currently no approved drug treatments for SCA in the United States. We are also developing troriluzole for the potential treatment of OCD and other indications. If we continue to pursue these indications, we would face substantial competition from companies that develop or sell products that treat OCD. With respect to BHV-5000, which we are developing for the treatment of neuropsychiatric conditions the market size and competition will depend on each indication. Many of the companies which we are competing with or which we may compete with in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. These third parties compete with us in recruiting and retaining qualified scientific and management personnel, 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 biopharmaceutical industry could result in even more resources being concentrated among our competitors. Competition may further increase as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in the biopharmaceutical industry. Our competitors may succeed in developing, acquiring or licensing, on an exclusive basis, products that are more effective or less costly than any product candidates that we may develop. Established biopharmaceutical companies may invest heavily to accelerate research and development of novel compounds or to in- license novel compounds that could make our product candidates less competitive. In addition, any new product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, and in discovering, developing, receiving FDA approval for or commercializing drugs before we do, which would have an adverse impact on our business and results of operations. The availability of our competitors’ products could limit the demand and the price we are able to charge for any product candidates we commercialize, if any. The inability to compete with existing or subsequently introduced drugs would harm our business, financial condition and results of operations. The successful commercialization of certain of our product candidates will depend in part on the extent to which governmental authorities and health insurers establish adequate coverage, reimbursement levels and pricing policies. Failure to obtain or maintain adequate coverage and reimbursement for our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue. The availability and adequacy of coverage and reimbursement by governmental healthcare programs, such as Medicare and Medicaid, private health insurers 48 Table of Contents and other third-party payors, are essential for most patients to be able to afford products such as our product candidates, if approved. Our ability to achieve acceptable levels of coverage and reimbursement for products by third-party payors will have an effect on our ability to successfully commercialize our product candidates, if approved, and attract additional collaboration partners to invest in the development of our product candidates. Assuming we obtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. We cannot be sure that coverage and adequate reimbursement in the United States, the European Union or elsewhere will be available for any product that we may develop, and any reimbursement that becomes available may be decreased or eliminated in the future. Third-party payors increasingly are challenging prices charged for pharmaceutical products and services, and many third-party payors may refuse to provide coverage and reimbursement for particular drugs when an equivalent generic drug or a less expensive therapy is available. Our competitors may offer their products and services on a less expensive basis to gain coverage and reimbursement from third- party payors. It is possible that a third-party payor may consider our product candidates as substitutable by less expensive therapies and only offer to reimburse patients for the less expensive product. Even if we show improved efficacy or improved convenience of administration with our product candidates, pricing of existing drugs may limit the amount we will be able to charge for our product candidates, once approved. These payors may deny or revoke the reimbursement status of a given product or establish prices for new or existing marketed products at levels that are too low to enable us to realize an appropriate return on our investment in product development. There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the United States, third-party payors, including private and governmental payors, play an important role in determining the extent to which new drugs and biologics will be covered. The Medicare and Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their coverage and reimbursement policies for drugs and biologics. Some third-party payors may require pre-approval of coverage for new or innovative devices or drug therapies before they will reimburse healthcare providers who use such devices or therapies. Obtaining and maintaining reimbursement status is time- consuming and costly. No uniform policy for coverage and reimbursement for products exists among third-party payors in the United States. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance. Furthermore, rules and regulations regarding reimbursement change frequently, in some cases at short notice, and we believe that changes in these rules and regulations are likely. Moreover, increasing efforts by governmental and third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations, and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare may adversely affect: • the demand for any products for which we may obtain regulatory approval; • our ability to set a price that we believe is fair for our products; • our ability to obtain coverage and adequate reimbursement approval for a product; • our ability to generate revenues and achieve or maintain profitability; and • the level of taxes that we are required to pay. Even if we obtain regulatory approval for our product candidates, they will remain subject to ongoing regulatory oversight. Even if we obtain regulatory approval for any of our product candidates, they will be subject to extensive and ongoing regulatory requirements for manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promoting, sampling and record-keeping. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing practices (“cGMP”) regulations and GCPs, for any clinical trials that we conduct post-approval, all of which may result in significant expense and limit our ability to commercialize such products. In addition, any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including 49 Table of Contents Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require a REMS as a condition of approval of our product candidates, which could include requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. We may not be able to adapt to changes in existing requirements or the adoption of new requirements or policies. If there are changes in the application of legislation or regulatory policies, or if problems are discovered with a product or our manufacture of a product, or if we or one of our distributors, licensees or co-marketers fails to comply with regulatory requirements, the regulators could take various actions. These include: • issuing warning or untitled letters; • seeking an injunction or imposing civil or criminal penalties or monetary fines; • suspension or imposition of restrictions on operations, including product manufacturing; • seizure or detention of products, refusal to permit the import or export of products, or requesting that we initiate a product recall; our business, financial condition and results of operations. Even if any of our product candidates receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success. Even if the FDA approves the marketing of any product candidates that we develop, physicians, patients, third-party payors or the medical community may not accept or use them. Efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may not be successful. Such efforts may require more resources than are typically required due to the complexity and uniqueness of our product candidates. If any of our product candidates do not achieve an adequate level of acceptance, we may not generate significant product revenue or any profits from operations. Because we expect sales of our product candidates, if approved, to generate substantially all of our product revenue for the foreseeable future, the failure of our product candidates to find market acceptance would harm our business and could require us to seek additional financing. The degree of market acceptance of our product candidates that are approved for commercial sale will depend on a variety of factors, including: • the efficacy, cost, convenience and ease of administration, and other potential advantages compared to alternative treatments, including any similar generic treatments; • suspension or withdrawal of our marketing authorizations; • effectiveness of sales and marketing efforts; • suspension of any ongoing clinical trials; • refusal to approve pending applications or supplements to applications submitted by us; • • refusal to permit the import or export of products; or requiring us to conduct additional clinical trials, change our product labeling or submit additional applications for marketing authorization. Moreover, the FDA strictly regulates the promotional claims that may be made about drug products. In particular, a product may not be promoted for uses that are not approved by the FDA as reflected in the product’s approved labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off- label uses may be subject to significant civil, criminal and administrative penalties. If any of these events occurs, our ability to sell such product may be impaired, and we may incur substantial additional expenses to comply with regulatory requirements, which could adversely affect • the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; • the strength of marketing and distribution support; • the availability of third-party coverage and adequate reimbursement, and patients’ willingness to pay out-of-pocket in the absence of third-party coverage or adequate reimbursement; • the prevalence and severity of any side effects; and • any restrictions on the use of our products, if approved, together with other medications. In addition, the potential market opportunity for our product candidates is difficult to estimate precisely. Our estimates of the potential market opportunity are predicated on several key assumptions such as industry knowledge and publications, third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, these assumptions may be inaccurate. If any of the assumptions proves to be inaccurate, then the actual 50 Table of Contents market for our product candidates could be smaller than our estimates of the potential market opportunity, our revenue from product sales may be limited and we may be unable to achieve or maintain profitability. Competition that our products may face from generic versions of our products could materially and adversely impact our future revenue, profitability and cash flows and substantially limit our ability to obtain a return on the investments we have made in those product candidates. If the FDA or comparable foreign regulatory authorities Risks Related to Our Dependence on Third Parties approve generic versions of any of our products that receive marketing approval, or such authorities do not grant our products sufficient periods of exclusivity before approving generic versions of our products, the sales of our products could be adversely affected. Once an NDA is approved, the product covered thereby becomes a “reference listed drug” in the FDA’s publication, “Approved Drug Products with Therapeutic Equivalence Evaluations,” commonly known as the Orange Book. Manufacturers may seek approval of generic versions of reference listed drugs through submission of abbreviated new drug applications (“ANDAs”) in the United States. In support of an ANDA, a generic manufacturer need not conduct clinical trials. Rather, the applicant generally must show that its product has the same active ingredient(s), dosage form, strength, route of administration and conditions of use or labeling as the reference listed drug and that the generic version is bioequivalent to the reference listed drug, meaning it is absorbed in the body at the same rate and to the same extent. Generic products may be significantly less costly to bring to market than the reference listed drug and companies that produce generic products are generally able to offer them at lower prices. Thus, following the introduction of a generic drug, a significant percentage of the sales of any branded product or reference listed drug is typically lost to the generic product. The FDA may not approve an ANDA for a generic product until any applicable period of non-patent exclusivity for the reference listed drug has expired. The U.S. Federal Food, Drug, and Cosmetic Act (“FDCA”) provides a period of five years of non-patent exclusivity for a new drug containing a new chemical element (“NCE”). Specifically, in cases where such exclusivity has been granted, an ANDA may not be submitted to the FDA until the expiration of five years unless the submission is accompanied by a Paragraph IV certification that a patent covering the reference listed drug is either invalid or will not be infringed by the generic product, in which case the applicant may submit its application four years following approval of the reference listed drug. While we believe that troriluzole, a prodrug of riluzole will be treated as NCEs under current FDA interpretations and, therefore, if approved, should be afforded five years of data exclusivity, the FDA may disagree with that conclusion and may approve generic products after a period that is less than five years. Manufacturers may seek to launch these generic products following the expiration of the applicable marketing exclusivity period, even if we still have patent protection for our product. We rely on third parties to conduct our preclinical studies and clinical trials and if these third parties perform in an unsatisfactory manner, our business could be substantially harmed. We have historically conducted, and we intend to continue to conduct our clinical trials using our own clinical resources, while also leveraging expertise and assistance from medical institutions, clinical investigators, contract laboratories and other third parties, such as contract research organizations (“CROs”) as appropriate. We are reliant upon such third parties to assist us in conducting GCP- compliant clinical trials on our product candidates properly and on time, and may not currently have all of the necessary contractual relationships in place to do so. Once we have established contractual relationships with such third-parties, we will have only limited control over their actual performance of these activities. We and our CROs and other vendors are required to comply with cGMP, GCP and good laboratory practices (“GLP”), which are regulations and guidelines enforced by the FDA, the Competent Authorities of the Member States of the European Union and any comparable foreign regulatory authorities for all of our product candidates in preclinical and clinical development. Regulatory authorities enforce these regulations through periodic inspections of trial sponsors, principal investigators, clinical trial sites and other contractors. Although we rely on CROs to conduct any current or planned GLP-compliant preclinical studies and GCP-compliant clinical trials and have limited influence over their actual performance, we remain responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with its investigational plan and protocol and applicable laws and regulations, and our reliance on the CROs does not relieve us of our regulatory responsibilities. If we or any of our CROs or vendors fail to comply with applicable regulations, the data generated in our preclinical studies and clinical trials may be deemed unreliable and the FDA, EMA or any comparable foreign regulatory agency may require us to perform additional preclinical studies and clinical trials before approving our marketing applications. We cannot assure you that upon inspection by a given regulatory agency, such regulatory agency will determine that all of our clinical trials comply with GCP regulations. In addition, our clinical trials must be conducted with products produced under cGMP requirements. Our failure to comply with these requirements may require us to repeat clinical trials, which would delay the regulatory approval process. 51 Table of Contents While we will have agreements governing their activities, we are not, and will not be able to control whether or not our CROs devote sufficient time and resources to our future preclinical and clinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials, or other drug development activities which could harm our business. If our CROs do not successfully carry out their contractual duties or obligations, or fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reason, our clinical trials may be extended, delayed or terminated, the clinical data generated in our clinical trials may be deemed unreliable, and we may not be able to obtain regulatory approval for, or successfully commercialize any product candidate that we develop. As a result, our financial results and the commercial prospects for any product candidate that we develop would be harmed, our costs could increase, and our ability to generate revenue could be delayed. If our relationships with these CROs terminate, we may not be able to enter into arrangements with alternative CROs or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus, and could delay development and commercialization of our product candidates. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can negatively impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a negative impact on our business and financial condition. We rely completely on third-party contractors to supply, manufacture and distribute clinical drug supplies for our product candidates, including certain sole-source suppliers and manufacturers; we intend to rely on third parties for commercial supply, manufacturing and distribution if any of our product candidates receive regulatory approval; and we expect to rely on third parties for supply, manufacturing and distribution of preclinical, clinical and commercial supplies of any future product candidates. We do not currently have, nor do we plan to acquire, the internal infrastructure or capability to supply, manufacture or distribute preclinical, clinical or commercial quantities of drug substances or products. Our ability to develop our product candidates depends and our ability to commercially supply our products will depend, in part, on our ability to successfully obtain the active pharmaceutical ingredients (“APIs”) and other substances and materials used in our product candidates from third parties and to have finished products manufactured by third parties in accordance with regulatory requirements and in sufficient quantities for preclinical and clinical testing and commercialization. If we fail to develop and maintain supply relationships with these third parties, we may be unable to continue to develop or commercialize our product candidates. In addition, our results of operations and cash flows could be adversely impacted by any inability to obtain favorable terms from our suppliers, including any acceleration of payment terms to our suppliers and/or the imposition of more restrictive credit terms and other contractual requirements. While we have auditing rights with all our current manufacturing counterparties, we do not have direct control over the ability of our contract suppliers and manufacturers to maintain adequate capacity and capabilities to serve our needs, including quality control, quality assurance and qualified personnel. Although we are ultimately responsible for ensuring compliance with regulatory requirements such as cGMPs, we are dependent on our contract suppliers and manufacturers for day-to-day compliance with cGMPs for production of both APIs and finished products. Facilities used by our contract suppliers and manufacturers to produce the APIs and other substances and materials or finished products for commercial sale must pass inspection and be approved by the FDA and other relevant regulatory authorities. Our contract suppliers and manufacturers must comply with cGMP requirements enforced by the FDA through its facilities inspection program and review of submitted technical information. If our contract suppliers or manufacturers fail to achieve and maintain compliance with applicable laws and regulatory requirements, our business could be adversely affected in a number of ways, and cause, among other things: • an inability to initiate or continue clinical trials of our product candidates under development; • delay in submitting regulatory applications, or receiving regulatory approvals, for our product candidates; • subjecting third-party manufacturing facilities or our own facilities to additional inspections by regulatory authorities; • requirements to cease distribution or to recall batches of our product candidates; • suspension of manufacturing of our product candidates; • • revocation of obtained approvals; and inability to meet commercial demands for our product candidates in the event of approval. Further, if the safety of any product or product candidate or component is compromised due to a failure to adhere to applicable laws and regulatory requirements, or for other reasons, we may not be able 52 Table of Contents to successfully commercialize or obtain regulatory approval for the affected product or product candidate, and we may be held liable for injuries sustained as a result. Any of these factors could cause a delay or termination of preclinical studies, clinical trials or regulatory submissions or approvals of our product candidates, and could entail higher costs or result in our being unable to effectively commercialize our approved products on a timely basis, or at all. We may rely on certain third parties as the sole source of the materials they supply or the finished products they manufacture. We may also have sole-source suppliers for one or more of our other product candidates. Some of the APIs and other substances and materials used in our product candidates are currently available only from one or a limited number of domestic or foreign suppliers and foreign manufacturers and certain of our finished product candidates are manufactured by one or a limited number of contract manufacturers. In the event an existing supplier or manufacturer fails to supply or manufacture, as applicable, product on a timely basis or in the requested amount, fails to meet regulatory requirements or our specifications, becomes unavailable through business interruption or financial insolvency or loses its regulatory status as an approved source, or if we or our manufacturers are unable to renew current supply agreements when such agreements expire and we do not have a second supplier, we likely would incur added costs and delays in identifying or qualifying replacement suppliers, manufacturers and materials and there can be no assurance that replacements would be available to us on a timely basis, on acceptable terms or at all. In certain cases, we may be required to get regulatory approval to use alternative suppliers and manufacturers, and this process of approval could delay production of our products or development of product candidates indefinitely. We and our manufacturers do not currently maintain inventory of these APIs and other substances and materials. Any interruption in the supply of an API or other substance or material or in the manufacture of a finished product could have a material adverse effect on our business, financial condition, operating results and prospects. In addition, these contract manufacturers are or may be engaged with other companies to supply and manufacture materials or products for such companies, which also exposes our suppliers and manufacturers to regulatory risks for the production of such materials and products. As a result, failure to meet the regulatory requirements for the production of those materials and products may also affect the regulatory clearance of a contract supplier’s or manufacturer’s facility. If the FDA or a comparable foreign regulatory agency does not approve these facilities for the supply or manufacture of our product candidates, or if it withdraws its approval in the future, we may need to find alternative supply or manufacturing facilities, which would negatively impact our ability to develop, obtain regulatory approval of or market our product candidates, if approved. We expect to continue to depend on third-party contract suppliers and manufacturers for the foreseeable future, but supply and manufacturing arrangements do not guarantee that a contract supplier or manufacturer will provide services adequate for our needs. We and our contract suppliers and manufacturers may attempt to improve production processes, certain aspects of which are complex and unique, and we may encounter difficulties with new or existing processes. While we attempt to build in certain contractual obligations on such third-party suppliers and manufacturers, we may not be able to ensure that such third parties comply with these obligations. Depending on the extent of any difficulties encountered, we could experience an interruption in clinical or commercial supply, with the result that the development, regulatory approval or commercialization of our product candidates may be delayed or interrupted. In addition, third-party suppliers and manufacturers may have the ability to increase the price payable by us for the supply of the APIs and other substances and materials used in our product candidates, in some cases without our consent. Additionally, any damages to or destruction of our third-party manufacturers’ or suppliers’ facilities or equipment may significantly impair our ability to have our product candidates manufactured on a timely basis. Furthermore, if a contract manufacturer or supplier becomes financially distressed or insolvent, or discontinues our relationship beyond the term of any existing agreement for any other reason, this could result in substantial management time and expense to identify, qualify and transfer processes to alternative manufacturers or suppliers, and could lead to an interruption in clinical or commercial supply. In addition, the manufacturing facilities of certain of our suppliers are located outside of the United States. This may give rise to difficulties in importing our products or product candidates or their components into the United States or other countries as a result of, among other things, regulatory agency approval requirements or import inspections, incomplete or inaccurate import documentation or defective packaging. We, or third-party manufacturers on whom we rely, may be unable to successfully scale-up manufacturing of our product candidates in sufficient quality and quantity, which would delay or prevent us from developing our product candidates and commercializing approved products, if any. As we prepare for later-stage clinical trials and potential commercialization, we will need to take steps to increase the scale of production of our product candidates, which may include transferring production to new third-party suppliers or manufacturers. In order to conduct larger or late-stage scale clinical trials for 53 Table of Contents our product candidates and supply sufficient commercial quantities of the resulting drug product and its components, if that product candidate is approved for sale, our contract manufacturers and suppliers will need to produce our product candidates in larger quantities, more cost effectively and, in certain cases, at higher yields than they currently achieve. We, or our manufacturers, may be unable to successfully increase the manufacturing capacity for any of our product candidates in a timely or cost-effective manner, or at all. In addition, quality issues may arise during scale-up activities because of the inherent properties of a product candidate itself or of a product candidate in combination with other components added during the manufacturing and packaging process, or during shipping and storage of the APIs or the finished product. If we, or any of our manufacturers, are unable to successfully scale up the manufacture of our product candidates in sufficient quality and quantity, the development, testing, and clinical trials of that product candidate may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business. If we are unable to obtain or maintain third-party manufacturing for commercial supply of our product candidates, or to do so on commercially reasonable terms, we may not be able to develop and commercialize our product candidates successfully. We may in the future enter into collaborations with third parties to develop and commercialize our product candidates. If these collaborations are not successful, or if we are not able to establish or maintain these collaborations, our business could be harmed. Our product development programs and the potential commercialization of our product candidates will require substantial additional capital to fund expenses. For some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies for the future development and potential commercialization of those product candidates. Furthermore, we may find that our programs require the use of proprietary rights held by third parties, and the growth of our business may depend in part on our ability to acquire, in-license or use these proprietary rights. Collaboration arrangements are complex and time-consuming to negotiate, document, implement and maintain. We may not be successful in our efforts to establish and implement collaborations or other alternative arrangements, and the terms of any collaborations or other arrangements that we may establish may not be favorable to us. We face significant competition in seeking appropriate collaborators, and a number of more established companies may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider attractive. These established companies may have a competitive advantage over us due to their size, financial resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. 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 regulatory authorities, the potential market for the subject product candidate, the costs and complexities of manufacturing and delivering such product candidate to patients, competing or alternative 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, and industry and market conditions generally. We may also be restricted under existing license agreements from entering into agreements on certain terms with potential collaborators. Even if we are able to obtain a license to intellectual property of interest, we may not be able to secure exclusive rights, in which case others could use the same rights and compete with us. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators. Collaborations are subject to numerous risks, including for example, that the collaborators may not: adequately perform their obligations under the collaboration agreement; devote sufficient resources to the collaboration to ensure success; or agree with us on the strategy or tactical aspects of the collaboration. If any such potential future collaborations do not result in the successful development and commercialization of product candidates, or if one of our future 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, the development of our product candidates could be delayed and we may need additional resources to develop our product candidates. In addition, if one of our future collaborators terminates its agreement with us, we may find it more difficult to attract new collaborators and the perception of us in the business and financial communities could be adversely affected. All of the risks relating to product development, regulatory approval and commercialization apply to the activities of our potential future collaborators. Risks Related to Regulatory Compliance We are required to comply with a wide variety of laws and regulations, and are subject to regulation by various federal, state and foreign agencies, and our failure to comply with existing and future regulatory requirements could adversely affect our results of operations and financial condition. Enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our product candidates and may affect the prices we may set. 54 Table of Contents Our operations are subject to a broad array of regulatory • new requirements to report certain financial arrangements with requirements globally. We are subject to federal, state, local, international and transnational laws and regulations, including the operating, quality and security standards of the FDA, the U.S. Department of Health and Human Services (“HHS”), and other regulatory authorities such as the EMA, and in the future, any changes to such laws and regulations could adversely affect us. In particular, changes in the FDA’s regulation of drug discovery and development or manufacturing processes could adversely affect our results of operations and financial condition. We may be required to register for permits and/or licenses with the FDA, HHS, or other regulatory authorities such as the EMA, and there can be no assurance that we will be able to maintain or renew existing permits, licenses or other regulatory approvals or obtain, without significant delay, future permits, licenses or other approvals needed for the operation of our business. Any noncompliance by us with applicable laws and regulations or the failure to maintain, renew or obtain necessary permits and licenses could have an adverse effect on our results of operations and financial condition. In the United States, the European Union, and other foreign jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes and proposed changes to the healthcare system that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state levels that seek to reduce healthcare costs and improve the quality of healthcare. For example, in March 2010, the Affordable Care Act (“ACA”), as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, ACA, was enacted, which substantially changed the way healthcare is financed by both governmental and private insurers. Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states, without specifically ruling on the ACA’s constitutionality. Among the provisions of the ACA, those of greatest importance to the pharmaceutical and biotechnology industries include: • an annual, non-deductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic agents, which is apportioned among these entities according to their market share in certain government healthcare programs; • a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; physicians and certain others, including reporting “transfers of value” made or distributed to prescribers and other healthcare providers and reporting investment interests held by physicians and their immediate family members; • an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the average manufacturer price for branded and generic drugs, respectively; • a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected; • extension of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; • expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to certain individuals with income at or below 133% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability; • expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; • a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for such research; and • establishment of the Center for Medicare Innovation at the Centers for Medicare and Medicaid Services (“CMS”), to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug spending. Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives. For example, CMS is developing new payment and delivery models, such as bundled payment models. HHS moved 30% of Medicare payments to alternative payment models tied to the quality or value of services in 2016. Additionally, HHS had set a goal of moving 50% of Medicare payments into these alternative payment models by the end of 2018, but in 2019, it discontinued this performance goal and replaced it with a new developmental goal to increase the percentage of Medicare health care dollars tied to APMs incorporating downside risk, with a target of 40% for fiscal year 2021. We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures. 55 Table of Contents Further, there have been several U.S. congressional inquiries and proposed and enacted state and federal legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs of drugs under Medicare and reform government program reimbursement methodologies for drug products. HHS has already started the process of soliciting feedback on some of these measures and, at the same time, is immediately implementing others under its existing authority. For example, CMS allows Medicare Advantage Plans the option to use step therapy for Part B drugs in 2019, CMS finalized a new rule that would require direct-to-consumer television advertisements of prescription drugs and biological products, for which payment is available through or under Medicare or Medicaid, to include in the advertisement the Wholesale Acquisition Cost, or list price, of that drug or biological product. However, this rule was struck down by a federal court before it went into effect. Although some of these and other proposals will require authorization through additional legislation to become effective, members of Congress and the Biden Administration have stated that they will continue to seek new legislative and administrative measures to control drug costs. In response to an Executive Order from President Biden, the Secretary of HHS issued a comprehensive plan for addressing high drug prices that describes a number of legislative approaches and identifies administrative tools to address the high cost of drugs. Democrats included drug pricing reform provisions reflecting elements of the plan in a broader spending package in late 2021—such as capping Medicare Part D patients’ out-of-pocket costs, establishing penalties for drug prices that increase faster than inflation in Medicare, and authorizing the federal government to negotiate prices on certain select, high-cost drugs under Medicare Parts B and D. At the state level, legislatures are increasingly 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. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities 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 healthcare programs. This could reduce the ultimate demand for our products or put pressure on our product pricing, which could negatively affect our business, results of operations, financial condition and prospects. On May 30, 2018, the Trickett Wendler, Frank Mongiello, Jordan McLinn, and Matthew Bellina Right to Try Act of 2017 was signed into law. The law, among other things, provides a federal framework for patients to access certain investigational new drug products that have completed a Phase 1 clinical trial. Under certain circumstances, eligible patients can seek treatment without enrolling in clinical trials and without obtaining FDA approval under the FDA expanded access program. In the European Union (“EU”), similar political, economic and regulatory developments may affect our ability to profitably commercialize any of our product candidates, if approved. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles that may increase our operating costs. The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most EU member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize any products for which we obtain marketing approval. In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we or our collaborators are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our business. 56 Table of Contents Our business operations and current and future relationships with investigators, healthcare professionals, consultants, third- party payors and customers will be subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, false claims laws, health information privacy and security laws, and other healthcare laws and regulations. If we are unable to comply, or have not fully complied, with such laws, we could face substantial penalties. Although we do not currently have any products on the market, if we obtain FDA approval for our product candidates, and begin commercializing those products in the United States, our operations may be directly, or indirectly through our prescribers, customers and third-party payors, subject to various U.S. federal and state healthcare laws and regulations, including, without limitation, the U.S. federal Anti- Kickback Statute, the U.S. federal civil and criminal false claims laws and Physician Payments Sunshine Act and regulations. Healthcare providers, physicians and others play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. These laws may impact, among other things, our current business operations, including our clinical research activities proposed sales and marketing and education programs and constrain the business or financial arrangements and relationships with healthcare providers, physicians and other parties through which we market, sell and distribute our products for which we obtain marketing approval. In addition, we may be subject to patient data privacy and security regulation by both the U.S. federal government and the states in which we conduct our business. Finally, we may be subject to additional healthcare, statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which we conduct our business. The U.S. laws that may affect our ability to operate include: • the U.S. federal Anti-Kickback Statute, which prohibits, among other things, persons or entities from knowingly and willfully soliciting, offering, receiving or paying any remuneration (including any kickback, bribe, or certain rebates), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, under U.S. federal and state healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; • the U.S. federal false claims and civil monetary penalties laws, including the civil False Claims Act, which, among other things, impose criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the U.S. federal government, claims for payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim, or from knowingly making a false statement to avoid, decrease or conceal an obligation to pay money to the U.S. federal government. In addition, the government may assert that a claim including items and services resulting from a violation of the U.S. federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act; • the U.S. federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) which imposes criminal and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement, in connection with the delivery of, or payment for, healthcare benefits, items or services; similar to the U.S. federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation; • HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act (“HITECH”) enacted as part of the American Recovery and Reinvestment Act of 2009, and its implementing regulations, and as amended again by the Modifications to the HIPAA Privacy, Security, Enforcement and Breach Notification Rules Under HITECH and the Genetic Information Nondiscrimination Act; Other Modifications to the HIPAA Rules, commonly referred to as the Final HIPAA Omnibus Rule, published in January 2013, which imposes certain obligations, including mandatory contractual terms, on covered entities subject to HIPAA (i.e., health plans, healthcare clearinghouses and certain healthcare providers), as well as their business associates that perform certain services for or on their behalf involving the use or disclosure of individually identifiable health information, to safeguard the privacy, security and transmission of individually identifiable health information from any unauthorized use or disclosure; • the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medical devices; • the U.S. federal Physician Payments Sunshine Act, enacted as part of the ACA, and its implementing regulations, which require certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid, or the Children’s Health Insurance Program to report annually to CMS information related to certain payments and other transfers of value to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by the physicians described above and their immediate family members; 57 Table of Contents • analogous state laws and regulations, including: state anti- kickback and false claims laws, which may apply to our business practices, including, but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers; with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs and imprisonment. If any of the above occur, it could adversely affect our ability to operate our business and our results of operations. We may not be able to obtain or maintain orphan drug • state laws that require pharmaceutical companies to comply designation or exclusivity for our product candidates. with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources; • state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information, which requires tracking gifts and other remuneration and items of value provided to healthcare professionals and entities; • state and local laws that require the registration of pharmaceutical sales representatives; and • state laws governing the privacy and security of personal information, including personal health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. Ensuring that our internal operations and current and future business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from U.S. government funded healthcare programs, such as Medicare and Medicaid, or similar programs in other countries or jurisdictions, disgorgement, individual imprisonment, contractual damages, reputational harm, diminished profits, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations. Further, defending against any such actions can be costly, time- consuming and may require significant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whom we expect to do business is found to not be in compliance We have obtained orphan drug designation in the United States for troriluzole in SCA. We may seek orphan drug designation for other product candidates in the future. Regulatory authorities in some jurisdictions, including the United States and the European Union, may designate drugs for relatively small patient populations as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug intended to treat a rare disease or condition, which is generally defined as a patient population of fewer than 200,000 individuals in the United States. Generally, if a product with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA or the EMA from approving another marketing application for the same drug for the same indication during that time period. The applicable period is seven years in the United States and ten years in the European Union. The European exclusivity period can be reduced to six years if a drug no longer meets the criteria for orphan drug designation or if the drug is sufficiently profitable so that market exclusivity is no longer justified. Orphan drug exclusivity may be lost if the FDA or the EMA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet the needs of patients with the rare disease or condition. We cannot assure you that any future application for orphan drug designation with respect to any other product candidate will be granted. If we are unable to obtain orphan drug designation with respect to other product candidates in the United States, we will not be eligible to obtain the period of market exclusivity that could result from orphan drug designation or be afforded the financial incentives associated with orphan drug designation. Even when we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. Even after an orphan drug is approved, the FDA can subsequently approve a later drug for the same condition if the FDA concludes that the later drug is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care. 58 Table of Contents We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that have increased both our costs and the risk of non- compliance. We are subject to rules and regulations by various governing bodies, including, for example, the SEC, which is charged with the protection of investors and the oversight of companies whose securities are publicly traded, and to new and evolving regulatory measures under applicable law, including the laws of the BVI. Our efforts to comply with new and changing laws and regulations have resulted in and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to our disclosure and governance practices. If we fail to address and comply with these regulations and any subsequent changes, we may be subject to penalty and our business may be harmed. Potential changes to regulatory legislation in the British Virgin Islands could lead to increased costs for us to comply with additional regulatory and reporting requirements. As the global regulatory and tax environment evolves, we may be subject to new or different statutory and regulatory requirements. For example, on January 1, 2019, the Economic Substance (Companies and Limited Partnerships) Act, 2018 of the British Virgin Islands (the “Economic Substance Act”) came into force and was amended on October 1, 2019 and June 29, 2021 and remains subject to further amendments, additional regulations and guidance on interpretation from the regulator. It is difficult to predict what impact the Economic Substance Act and its associated regulations and guidance or changes in the interpretation of these laws or regulations could have on us. However, compliance with various additional obligations may create additional costs that may be borne by us or otherwise affect our management and operation. Risks Related to Our Intellectual Property We could lose market exclusivity earlier than expected. We own or license patents in the U.S. and foreign countries that protect our products, their methods of use and manufacture, as well as other innovations relating to the advancement of our science to help bring new therapies to patients. We also develop brand names and trademarks for our products to differentiate them in the marketplace. We consider the overall protection of our patents, trademarks, licenses and other intellectual property rights to be of material value and act to protect these rights from infringement. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection for commercially important technology, inventions and know-how related to our business, defend and enforce our patents, preserve the confidentiality of our trade secrets and operate without infringing the valid and enforceable patents and other proprietary rights of third parties. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop, strengthen and maintain the proprietary position of our products and development programs. In the biopharmaceutical industry, a substantial portion of an innovative product’s commercial value is usually realized during the period in which the product has market exclusivity. A product’s market exclusivity is generally determined by two forms of intellectual property: patent rights held by the innovator company and any regulatory forms of exclusivity to which the innovative drug is entitled. Patents are a key determinant of market exclusivity for most pharmaceuticals. Patents provide the innovator with the right to exclude others from practicing an invention related to the medicine. Patents may cover, among other things, the active ingredient(s), various uses of a drug product, discovery tools, pharmaceutical formulations, drug delivery mechanisms and processes for (or intermediates useful in) the manufacture of products. Protection for individual products extends for varying periods in accordance with the expiration dates of patents in the various countries. The protection afforded, which may also vary from country to country, depends upon the type of patent, its scope of coverage and the availability of meaningful legal remedies in the country. Market exclusivity can also be influenced by regulatory data protection (“RDP”). Many developed countries provide certain non- patent incentives for the development of medicines. For example, in the U.S., the EU, United Kingdom, Japan, and certain other countries, RDP intellectual property rights are offered to: (i) provide a time period of data protection during which a generic company is not allowed to rely on the innovator’s data in seeking approval; (ii) restore patent term lost during drug development and approval; and (iii) provide incentives for research on medicines for rare diseases, or orphan drugs, and on medicines useful in treating pediatric patients. These incentives can extend the market exclusivity period on a product beyond the patent term. In the United States, biopharmaceutical products are protected by patents with varying terms depending on the type of patent and the filing date. A significant portion of a product’s patent life, however, is lost during the time it takes an innovative company to develop and obtain regulatory approval of a new drug. As 59 Table of Contents compensation, at least in part, for the lost patent term due to regulatory review periods, the innovator may, depending on a number of factors, apply to the government to restore lost patent term by extending the expiration date of one patent up to a maximum term of five years, provided that the extension cannot cause the patent to be in effect for more than 14 years from the date of drug approval. A company seeking to market an innovative pharmaceutical in the U.S. must submit a complete set of safety and efficacy data to the FDA. If the innovative pharmaceutical is a chemical product, the company files an NDA. If the medicine is a biological product, a BLA is filed. The type of application filed affects RDP exclusivity rights. A competitor seeking to launch a generic substitute of small molecule drug in the U.S. must file an ANDA with the FDA. In the ANDA, the generic manufacturer needs to demonstrate only “bioequivalence” between the generic substitute and the approved NDA drug. The ANDA relies upon the safety and efficacy data previously filed by the innovator in its NDA. An innovator company is required to list certain of its patents covering the medicine with the FDA in what is commonly known as the FDA’s Orange Book. The FDA cannot approve an ANDA until after the innovator’s listed patents expire unless there is a successful patent challenge. However, after the innovator has marketed its product for four years, a generic manufacturer may file an ANDA and allege that one or more of the patents listed in the Orange Book under an innovator’s NDA is either invalid or not infringed (a Paragraph IV certification). The innovator then must decide whether to file a patent infringement suit against the generic manufacturer. From time to time, ANDAs, including Paragraph IV certifications, are filed with respect to certain of our products. In addition to patent protection, certain innovative pharmaceutical products can receive periods of regulatory exclusivity. An NDA that is designated as an orphan drug can receive seven years of exclusivity for the orphan indication. During this time period, neither NDAs nor ANDAs for the same drug product can be approved for the same orphan use. A company may also earn six months of additional exclusivity for a drug where specific clinical studies are conducted at the written request of the FDA to study the use of the medicine to treat pediatric patients, and submission to the FDA is made prior to the loss of basic exclusivity. Medicines approved under an NDA can also receive several types of RDP. An innovative chemical pharmaceutical product is entitled to five years of RDP in the U.S., during which the FDA cannot approve generic substitutes. If an innovator’s patent is challenged, as described above, a generic manufacturer may file its ANDA after the fourth year of the five-year RDP period. A pharmaceutical drug product that contains an active ingredient that has been previously approved in an NDA, but is approved in a new formulation, but not for the drug itself, or for a new indication on the basis of new clinical studies, may receive three years of RDP for that formulation or indication. In the U.S., the FDA can approve products that are similar to (but not generic copies of) innovative biologics on the basis of less extensive data than is required by a full BLA. After an innovator has marketed its product for four years, any manufacturer may file an application for approval of a “biosimilar” version of the innovator product. However, although an application for approval of a biosimilar version may be filed four years after approval of the innovator product, qualified innovative biological products will receive 12 years of regulatory exclusivity, meaning that the FDA may not approve a biosimilar version until 12 years after the innovative biological product was first approved by the FDA. The law also provides a mechanism for innovators to enforce the patents that protect innovative biological products and for biosimilar applicants to challenge the patents. Such patent litigation may begin as early as four years after the innovative biological product is first approved by the FDA. In the U.S., the increased likelihood of generic and biosimilar challenges to innovators’ intellectual property has increased the risk of loss of innovators’ market exclusivity. First, generic companies have increasingly sought to challenge innovators’ basic patents covering major pharmaceutical products. Second, statutory and regulatory provisions in the U.S. limit the ability of an innovator company to prevent generic and biosimilar drugs from being approved and launched while patent litigation is ongoing. As a result of all of these developments, it is not possible to predict the length of market exclusivity for a particular product with certainty based solely on the expiration of the relevant patent(s) or the current forms of regulatory exclusivity. In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Although many of the issues discussed above with respect to the United States apply similarly in the context of the European Union and other geographies, the approval process 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 from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others. A typical route used by innovator companies to obtain marketing authorization of pharmaceutical products in the EU is through the “centralized procedure.” A company seeking to market an innovative 60 Table of Contents pharmaceutical product through the centralized procedure must file a complete set of safety data and efficacy data as part of a Marketing Authorisation Application (“MAA”) with the EMA. After the EMA evaluates the MAA, it provides a recommendation to the EC and the EC then approves or denies the MAA. It is also possible for new chemical products to obtain marketing authorization in the EU through a “mutual recognition procedure,” in which an application is made to a single member state, and if the member state approves the pharmaceutical product under a national procedure, then the applicant may submit that approval to the mutual recognition procedure of some or all other member states. After obtaining marketing authorization approval, a company must obtain pricing and reimbursement for the pharmaceutical product, which is typically subject to member state law. In certain EU countries, this process can take place simultaneously while the product is marketed but in other EU countries, this process must be completed before the company can market the new product. The pricing and reimbursement procedure can take months and sometimes years to complete. Throughout the EU, all products for which marketing authorizations have been filed after October/November 2005 are subject to an “8+2+1” regime. Eight years after the innovator has received its first community authorization for a medicinal product, a generic company may file a MAA for that product with the health authorities. If the MAA is approved, the generic company may not commercialize the product until after either 10 or 11 years have elapsed from the initial marketing authorization granted to the innovator. The possible extension to 11 years is available if the innovator, during the first eight years of the marketing authorization, obtains an additional indication that is of significant clinical benefit in comparison with existing treatments. In contrast to the U.S., patents in the EU are not listed with regulatory authorities. Generic versions of pharmaceutical products can be approved after data protection expires, regardless of whether the innovator holds patents covering its drug. Thus, it is possible that an innovator may be seeking to enforce its patents against a generic competitor that is already marketing its product. Also, the European patent system has an opposition procedure in which generic manufacturers may challenge the validity of patents covering innovator products within nine months of grant. In general, EU law treats chemically-synthesized drugs and biologically- derived drugs the same with respect to intellectual property and data protection. In addition to the relevant legislation and annexes related to biologic medicinal products, the EMA has issued guidelines that outline the additional information to be provided for biosimilar products, also known as generic biologics, in order to review an application for marketing approval. In Japan, medicines of new chemical entities are generally afforded eight years of data exclusivity for approved indications and dosage. Patents on pharmaceutical products are enforceable. Generic copies can receive regulatory approval after data exclusivity and patent expirations. As in the U.S., patents in Japan may be extended to compensate for the patent term lost during the regulatory review process. In general, Japanese law treats chemically-synthesized and biologically-derived drugs the same with respect to intellectual property and market exclusivity. In countries outside of the U.S., the EU and Japan, there is a wide variety of legal systems with respect to intellectual property and market exclusivity of pharmaceuticals. Most other developed countries utilize systems similar to either the U.S. or the EU. Among developing countries, some have adopted patent laws and/or regulatory exclusivity laws, while others have not. Some developing countries have formally adopted laws in order to comply with World Trade Organization (“WTO”) commitments, but have not taken steps to implement these laws in a meaningful way. Enforcement of WTO actions is a long process between governments, and there is no assurance of the outcome. We are dependent on licensed intellectual property in our business. If we are unable to obtain licenses from third parties on commercially reasonable terms or lose our rights to such licensed intellectual property, or if our rights are determined to be narrower than we understand them to be, we may not be able to continue developing or commercializing our product candidates. We are a party to a number of license agreements under which we are granted rights to intellectual property that are important to our business, including, for example, a license agreement with ALS Biopharma and Fox Chase Chemical Diversity Center, Inc., pursuant to which we were assigned intellectual property rights relating to troriluzole, license agreements with AstraZeneca, pursuant to which we were granted exclusive licenses relating to BHV-5500, a license agreement with Bristol-Myers Squibb, pursuant to which we were granted an exclusive license to BHV-2000, and a license agreement with KU Leuven, pursuant to which we were granted an exclusive license to develop and commercialize the TRPM3 antagonist platform. We may enter into additional license agreements in the future. Our existing license agreements impose, and we expect that future license agreements will impose on us, various development, regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations, such as non-compete periods for certain collaboration targets and rights of first negotiation for development of certain programs. Typically, in our licenses, we have control over the filing, prosecution, maintenance and enforcement of the licensed intellectual property. However, in some cases, we may not control prosecution of the licensed intellectual property, or may not have the first right to enforce such intellectual property. In those cases, we may not be able to adequately influence patent prosecution or enforcement, or prevent inadvertent lapses of coverage due to failure to pay maintenance fees. If we fail to comply with any of our obligations under a current or future license agreement, the 61 Table of Contents licensor may allege that we have breached our license agreement, and may seek to terminate our license. Termination of any of our current or future licenses could result in our loss of the right to use the licensed intellectual property, which could materially adversely affect our ability to develop, manufacture or commercialize a product candidate or product, if approved, as well as harm our competitive business position and our business prospects. Under some license agreements, termination may also result in the transfer of or granting of rights under certain of our intellectual property and information related to the product candidate being developed under the license, such as regulatory information. If our licensors fail to comply with their obligations under these agreements, such as, for example, by failing to maintain or enforce patents licensed to us, exclusivity relating to the products covered by the license may be diminished or lost. Our rights under license agreements could be determined to be narrower than we understand them to be. Also, if it is found that our licensors were not the original inventors of the licensed intellectual property, or were not the first to file patent applications, then we may lose rights to the licensed intellectual property. Licensing of intellectual property is important to our business and involves complex legal, business and scientific issues. Disputes between us and our licensors have arisen and may arise in the future. For example, disputes may arise between us and our licensors regarding intellectual property subject to a license agreement, including: • the scope of rights granted under the license agreement and other interpretation-related issues, including our right to sublicense patents and other rights to third parties; • whether and the extent to which our technology and processes infringe on intellectual property of the licensor that is not subject to the licensing agreement; • our diligence obligations with respect to the use of the licensed technology in relation to our development and commercialization of our product candidates, and what activities satisfy those diligence obligations; • the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our licensors and us and our partners; • our right to transfer or assign the license; and • the effects of termination. If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop, manufacture or commercialize the affected product candidates. It may be necessary or desirable for us to use the patented or proprietary technology of third parties to commercialize our products, in which case we would seek to obtain a license from these third parties. If we are unable to license such technology, or if we are forced to license such technology on unfavorable terms, our business could be harmed. If we are unable to obtain a necessary license, we may be unable to develop or commercialize the affected product candidates, which could materially harm our business and the third parties owning such intellectual property rights could seek either an injunction prohibiting our sales or payment of royalties and/or other forms of compensation. Even if we are able to obtain a license, it may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. Patent terms may not provide exclusivity for our product candidates for an adequate amount of time for us to realize commercial benefits. Patents have a limited lifespan. In the United States and most of the world, the statutory expiration of a patent is generally 20 years from the first filing date. Even if patents covering our product candidates are obtained, once the patent life has expired for a product candidate, we may be open to competition from competitive products, including generic products. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such product candidates may not provide us with exclusivity for an adequate amount of time for us to realize commercial benefits. Depending upon the timing, duration and conditions of FDA marketing approval of our product candidates, one or more of our U.S. patents may be eligible for limited patent term restoration under the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Amendments, and similar legislation in the European Union. The Hatch-Waxman Amendments permit a patent term extension of up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process, subject to a statutory maximum of fourteen (14) years from the regulatory approval and an additional six months of pediatric exclusivity if available. Similar regulations regarding patent term extensions, or supplementary protection certificates, are available in some countries such as the European Union, United Kingdom, Japan and Korea. However, we may not receive a patent term restoration, a supplementary protection certificate or extension if we fail to satisfy applicable requirements. Moreover, the length of the extension could be less than we request. If we are unable to obtain a patent term restoration, a supplementary protection certificate or extension, or the term is less than we request, the period during which we can enforce our patent rights for that product will be shortened and our competitors may obtain approval to market competing products sooner. As a result, our revenue from applicable products could be reduced. 62 Table of Contents Third parties may seek to invalidate our patents. Once granted, patents may remain open to invalidity challenges including opposition, interference, re-examination, post-grant review, inter partes review, nullification or derivation actions in court or before patent offices or similar proceedings for a given period after allowance or grant, during which time third parties can raise objections against such grant. In the course of such proceedings, which may continue for a protracted period of time, the patent owner may be compelled to limit the scope of the allowed or granted claims which are the subject of the challenge, or may lose the allowed or granted claims altogether. Generic manufacturers seeking to launch a generic substitute of small molecule drug in the U.S. typically engage in patent challenges. We expect that as early as four (4) years after the approval of our products, one or more generic manufactures may allege that one or more of the patents listed in the Orange Book under our NDA is either invalid or not infringed (a Paragraph IV certification). We then must decide whether to file a patent infringement suit against such generic manufacturer(s). Some claimants may have substantially greater resources than we do and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. Third parties may initiate legal proceedings alleging that we are infringing their intellectual property rights, the outcome of which would be uncertain and could have a negative impact on the success of our business. Third parties may assert infringement claims against us based on existing patents or patents that may be granted in the future, regardless of their merit. There is a risk that third parties may choose to engage in litigation with us to enforce or to otherwise assert their patent rights against us. Even if we believe such claims are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed, and the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtained a license under the applicable patents, or until such patents expire or are finally determined to be invalid or unenforceable. Similarly, if any third-party patents were held by a court of competent jurisdiction to cover aspects of our technology, such as our compositions, formulations, or methods of treatment, prevention or use, the holders of any such patents may be able to block our ability to develop and commercialize the applicable product candidate unless we obtained a license. Parties making claims against us may obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize one or more of our product candidates. If, in the context of seeking approval for one of our product candidates subject to approval via Section 505(b)(2), we were required to file a Paragraph IV certification against any patents of a third party, we would additionally be at risk of an automatic stay if litigation is initiated, thereby potentially delaying our approval or market entry. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of resources from our business. In the event of a successful claim of infringement against us, we may have to pay substantial damages, pay royalties, redesign our infringing products or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure. In addition to claims of infringement made by third parties against us, we may file claims of infringement against third parties who infringe, or misappropriate, our patents or those of our licensors. This can occur as a counter claim in an infringement suit against us or as a direct claim against the third party. Our adversaries in these proceedings may have the ability to dedicate substantially greater resources to prosecuting these legal actions than we can. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not valid or is unenforceable, or may 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 or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing. The initiation of a claim against a third party may also cause the third party to bring counter claims against us such as claims asserting that our patents are invalid or unenforceable or claims challenging the scope of the intellectual property rights we own or control. The outcome following legal assertions of invalidity and unenforceability is unpredictable. Other risk factors relating to our intellectual property. In addition to the risk factors described above, we consider the items below to be relevant for consideration in the assessment of the Company’s intellectual property position. • Changes in intellectual property laws or regulations in the U.S. or other countries could negatively affect our business. Similarly, changes in the interpretation of such laws or regulations could have an impact on our business. For example, U.S. Supreme Court has ruled on several patent cases in recent years, such as Impression Products, Inc. v. Lexmark International, Inc., Association for Molecular Pathology v. Myriad Genetics, Inc., Mayo Collaborative Services v. Prometheus Laboratories, Inc., and Alice Corporation Pty. Ltd. v. CLS Bank International, either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations. In addition to increasing 63 Table of Contents uncertainty with regard to our ability to obtain patents in the future, decisions by courts may lead to legislation impacting our ability to obtain or enforce our intellectual property. • Our ability to enforce our intellectual property outside of the U.S. is dependent on the laws of jurisdiction in which the alleged infringement occurred, the ability to engage in discovery to obtain evidence and the availability of meaningful recoveries, e.g., damages and injunctions. The laws of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights. As a result, our business may be harmed by limitations on our ability to protect our technology through the enforcement of our intellectual property in certain countries outside the U.S. • The U.S. government may seek to exercise its rights under the Bayh-Dole Act of 1980 in programs that have received government funding. This exercise of rights could require us to grant exclusive, partially exclusive, or non-exclusive licenses to any of these inventions to a third party the U.S. Government determines that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal regulations (also referred to as “march-in rights”). • We rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into confidentiality agreements with parties who have access to them, such as our employees, third party collaborators, contract manufacturers, consultants, advisors and other third parties. An unauthorized disclosure or use of our trade secrets can have an adverse impact on our business. • Other innovator companies may independently develop alternative technologies to our technologies without infringing our intellectual property rights, such as, for example, by developing compounds that function according to the same mechanism of action as our compounds, but are chemically distinct from ours and are not covered by the claims of the patents that we own or control. • Litigation involving intellectual property can be generally time consuming and expensive. Litigation or other legal proceedings relating to intellectual property claims is unpredictable and generally expensive and time-consuming and is likely to divert significant resources from our core business, including distracting our technical and management personnel from their normal responsibilities. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on our valuation. Risks Related to Our Business Operations, Employee Matters and Managing Growth Our future growth and ability to compete depends on retaining our key personnel and recruiting additional qualified personnel. We are highly dependent on the management, development, clinical, financial and business development experience of our senior management. Although we have entered into employment agreements with our executive officers, each of them may terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or employees. The competition for qualified personnel in the biopharmaceutical field is intense, and our future success depends upon our ability to attract, retain and motivate highly-skilled scientific, technical and managerial employees. We face competition for personnel from other companies, universities, public and private research institutions and other organizations. If our recruitment and retention efforts are unsuccessful in the future, it may be difficult for us to implement business strategy, which could harm our business. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our 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. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited. Our future growth depends, in part, on our ability to penetrate foreign markets, where we would be subject to additional regulatory burdens and other risks and uncertainties. Our future profitability will depend, in part, on our ability to commercialize our product candidates in markets outside of the United States and the European Union. If we commercialize our product candidates in foreign markets, we will be subject to additional risks and uncertainties, including: • economic weakness, including inflation, or political instability in particular economies and markets; 64 Table of Contents • the burden of complying with complex and changing foreign regulatory, tax, accounting and legal requirements, many of which vary between countries; • different medical practices and customs in foreign countries affecting acceptance in the marketplace; • tariffs and trade barriers; • other trade protection measures, import or export licensing requirements or other restrictive actions by U.S. or foreign governments; • • longer accounts receivable collection times; longer lead times for shipping; • compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; • workforce uncertainty in countries where labor unrest is common; • • language barriers for technical training; reduced protection of intellectual property rights in some foreign countries, and related prevalence of generic alternatives to therapeutics; • foreign currency exchange rate fluctuations and currency controls; • differing foreign reimbursement landscapes; • uncertain and potentially inadequate reimbursement of our products; and • the interpretation of contractual provisions governed by foreign laws in the event of a contract dispute. Foreign sales of our products could also be adversely affected by the imposition of governmental controls, political and economic instability, trade restrictions and changes in tariffs. Laws and regulations governing our international operations may preclude us from developing, manufacturing and selling certain product candidates and products outside of the United States and require us to develop and implement costly compliance programs. As we expand our operations outside of the United States, we will be required to dedicate additional resources to comply with numerous laws and regulations in each jurisdiction in which we plan to operate. We are subject to U.S. laws governing international business activities, including U.S. economic sanctions, export controls and anti- corruption laws, including the FCPA, compliance with which is expensive and difficult, particularly in countries in which corruption is a recognized problem. As a result, these laws may preclude us from developing, manufacturing or selling certain product candidates outside of the United States, which could limit our growth potential and increase our development costs. If our employees or agents violate our policies or we fail to maintain adequate record keeping and internal accounting practices to accurately record our transactions, we may be subject to regulatory sanctions. The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting. The SEC also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s accounting provisions. Violations of U.S. economic sanctions, export controls and anti-corruption laws, or allegations of such acts, could damage our reputation and subject us to civil or criminal investigations in the United States and in other jurisdictions and related shareholder lawsuits, could lead to substantial civil and criminal, monetary and nonmonetary penalties and could cause us to incur significant legal and investigatory fees which could adversely affect our business, consolidated financial condition and results of operations. We expect to expand our development and regulatory capabilities and potentially implement sales, marketing and distribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations. As our clinical development progresses, we expect to experience growth in the number of our employees and the scope of our operations, particularly in the areas of clinical operations, regulatory affairs and, if any of our product candidates receives marketing approval, sales, marketing and distribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to our limited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations. Our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs and vendors may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements. We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, CROs and vendors may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or unauthorized activities that violates (1) the laws and regulations of the FDA, the EMA and other similar 65 Table of Contents regulatory authorities, including those laws requiring the reporting of true, complete and accurate information to such authorities, (2) manufacturing standards, (3) federal and state data privacy, security, fraud and abuse and other healthcare laws and regulations in the United States and abroad and (4) laws that require the true, complete and accurate reporting of financial information or data. 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 may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of individually identifiable information, including information obtained in the course of clinical trials, creating fraudulent data in our preclinical studies or clinical trials or illegal misappropriation of product candidates, which could result in regulatory sanctions and serious harm to our reputation. Although we have adopted a code of business conduct and ethics, 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 effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. Additionally, we are subject to the risk that a person or government 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 significant civil, criminal and administrative penalties, including damages, fines, disgorgement, imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, contractual damages, reputational harm, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws and the curtailment or restructuring of our operations. We may be subject to securities litigation, which is expensive and could divert management attention. Our share price may be volatile, and in the past companies that have experienced volatility in the market price of their shares have been subject to securities class action litigation. This risk is especially relevant for us because biotechnology companies have experienced significant share price volatility in recent years. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business. Our business and operations may be materially adversely affected in the event of computer system failures or security breaches. Despite the implementation of security measures, our internal computer systems, and those of our CROs and other third parties on which we rely, are vulnerable to damage from computer viruses, unauthorized access, cyberattacks, natural disasters, fire, terrorism, war and telecommunication and electrical failures. If such an event were to occur and interrupt our operations, it could result in a material disruption of our development programs. For example, the loss of clinical trial data from ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach results in a loss of or damage to our data or applications, loss of trade secrets or inappropriate disclosure of confidential or proprietary information, including individually identifiable health information or the personal data of employees or former employees, access to our clinical data or disruption of the manufacturing process, we could incur liability and the further development of our product candidates could be delayed. We may also be vulnerable to cyberattacks by hackers or other malfeasance. This type of breach of our cybersecurity may compromise our confidential information or our financial information and adversely affect our business or result in legal proceedings. Additionally, the collection, use, disclosure, transfer, or other processing of personal data regarding individuals in the EU, including date concerning health, is subject to the EU General Data Protection Regulation, or GDPR, which became effective on May 25, 2018. The GDPR is wide-ranging in scope and imposes numerous requirements on companies that process personal data, including requirements relating to processing data concerning health and other sensitive data, obtaining consent of the individuals to whom the personal data relates to process their personal data, providing information 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 also imposes strict rules on the transfer of personal data to countries outside the EU, including the United States, 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 turnover, 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. 66 Table of Contents Risks Related to Ownership of Our Common Shares • announcements relating to our arrangements with An active trading market for our common shares may not be sustained, or be liquid enough for investors to resell our common shares quickly or at the market price. AstraZeneca; • community; failure to meet or exceed expectations of the investment Our common shares began trading on the NYSE on October 4, • actual or anticipated variations in our operating results; 2022. Although trading in our common shares has developed, we cannot assure you that an active trading market will continue to develop or be sustained or that any trading market will be liquid. If an active market for our common shares is not sustained, it may be difficult for our shareholders to sell shares without depressing the market price for the shares or to sell their shares at all. An inactive market may also impair our ability to raise capital to continue to fund operations by selling our common shares and may impair our ability to acquire other companies or technologies by using our common shares as consideration. The trading price of our common shares may be volatile and may fluctuate due to factors beyond our control, and purchasers of our common shares could incur substantial losses. Our share price may be volatile. The stock market in general and the market for biopharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, our shareholders and investors may not be able to sell their common shares at or above the price paid for the shares. The market price for our common shares may be influenced by many factors, including: • positive or negative results, including preliminary or topline results, of preclinical studies and clinical trials reported by us, strategic partners or competitors; • any progress or delay in the commencement, enrollment and the ultimate completion of clinical trials; • technological innovations or commercial product introductions by us or competitors; • failure to successfully develop and commercialize any of our product candidates; • developments, announcements or changes in government regulations relating to drug products, including related to drug pricing, reimbursement and healthcare coverage; • delays in in-licensing or acquiring additional complementary product candidates; • developments concerning proprietary rights, including patents and litigation matters; • public concern relating to the commercial value or safety of any of our product candidates; • financing or other corporate transactions, or inability to obtain additional funding; • changes in financial estimates by us or by any securities analysts who might cover our shares; • announcements by therapeutic drug product providers related to pricing of therapeutics; • announcements of significant licenses, acquisitions, strategic partnerships or joint ventures by us or our competitors; • publication of research reports or comments by securities or industry analysts; • failure to attract or retain of key personnel; • sales of our common shares, including sales by our directors and officers or specific shareholders; • general market or regulatory conditions in the pharmaceutical industry or in the economy as a whole; • other events and factors, many of which are beyond our control; and • other factors described in this “Risk Factors” section and elsewhere in this Annual Report on Form 10-K. These and other market and industry factors may cause the market price and demand for our securities to fluctuate substantially, regardless of our actual operating performance, which may limit or prevent investors from selling their common shares at or above the price paid for the shares and may otherwise negatively affect the liquidity of our common shares. Some companies that have experienced volatility in the trading price of their shares have been the subject of securities class action litigation. Any lawsuit to which we are a party, with or without merit, may result in an unfavorable judgment. We also may decide to settle lawsuits on unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our offerings or business practices. Defending against litigation is costly and time-consuming, and could divert our management’s attention and resources. Furthermore, during the course of litigation, there could be negative public announcements of the results of hearings, motions or other interim proceedings or developments, which could have a negative effect on the market price of our common shares. 67 Table of Contents If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our common shares and our trading volume could decline. • require that shareholder actions must be effected at a duly called shareholder meeting and prohibit actions by our shareholders by written consent; • limit the ability of members to requisition and convene general The trading market for our common shares will depend in part on meetings of members; and the research and reports that securities or industry analysts publish about us or our business. As a newly public company, we have only limited research coverage by equity research analysts. Additional equity research analysts may elect not to initiate, and our current equity research analysts may not elect to continue, to provide research coverage of our common shares, and such lack of research coverage may adversely affect the market price of our common shares. We do not have any control over the analysts or the content and opinions included in their reports. The price of our shares could decline if one or more equity research analysts downgrade our shares or issue other unfavorable commentary or research. If one or more equity research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our shares could decrease, which in turn could cause our share price or trading volume to decline. Anti-takeover provisions in our amended memorandum and articles of association (“Amended Memorandum and Articles of Association”) could make an acquisition of us, which may be beneficial to our shareholders, more difficult and may prevent attempts by our shareholders to replace or remove our current management and limit the market price of our common shares. Provisions in our Amended Memorandum and Articles of Association may discourage, delay or prevent a merger, acquisition or other change in control of us that shareholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. These provisions also could limit the price that investors might be willing to pay in the future for our common shares, thereby depressing the market price of our common shares. In addition, because our Board is responsible for appointing the members of our management team, these provisions may frustrate or prevent any attempts by our shareholders to replace or remove our current management by making it more difficult for shareholders to replace members of our Board. Among other things, these provisions: • establish a classified Board such that not all members of the Board are elected at one time; • allow the authorized number of our directors to be changed only by resolution of our Board; • limit the manner in which shareholders can remove directors from the Board; • establish advance notice requirements for shareholder proposals that can be acted on at shareholder meetings and nominations to our Board; • authorize our Board to issue preferred shares in one or more series and to designate the price, rights, preferences, privileges and restrictions of such preferred shares without any further vote or action by our members without shareholder approval, which could be used to institute a shareholder rights plan, or so-called “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. Any provision of our Amended Memorandum and Articles of Association or BVI law that has the effect of delaying or deterring a change of control could limit the opportunity for our shareholders to receive a premium for their common shares, and could also affect the price that some investors are willing to pay for our common shares. Substantially all of our total outstanding shares may be sold freely into the market. This could cause the market price of our common shares to drop significantly, even if our business is doing well. Sales of substantially all of our common shares in the public market, or the perception that these sales might occur, could depress the market price of our common shares and could impair our ability to raise capital through the sale of additional equity securities. Immediately following the Distribution, substantially all of our common shares became freely tradable, without restrictions or further registration under the Securities Act, subject to certain restrictions applicable to shares held by our affiliates as defined in Rule 144 under the Securities Act. Because we do not expect to pay dividends on our common shares in the foreseeable future, capital appreciation, if any, would be your sole source of gain. We have never declared or paid any dividends on our common shares. We currently anticipate that we will retain future earnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. The decision to pay future dividends to shareholders will be at the discretion of our Board after taking into account various factors including our business prospects, cash requirements, financial performance and new product development. Accordingly, investors cannot rely on dividend income from our common shares and any returns on an investment in our common shares will likely depend entirely upon any future appreciation in the price of our common shares. 68 Table of Contents We are an “emerging growth company,” and we cannot be certain if the reduced reporting requirements applicable to “emerging growth companies” will make our common shares less attractive to investors. We are an “emerging growth company,” as defined in the JOBS Act. For as long as we continue to be an “emerging growth company,” we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. As an “emerging growth company,” we are required to report only two years of financial results in certain Securities Act registration statements. We may take advantage of these exemptions until we are no longer an “emerging growth company.” We will remain an “emerging growth company” for up to five years after the effective date of the Registration Statement on Form S-1, filed by the Company with the SEC on October 18, 2022 (Reg. No. 333-267928), although we will lose that status sooner if our revenues exceed $1.235 billion, if we issue more than $1 billion in non-convertible debt in a three-year period, or if the market value of our common shares that are held by non-affiliates exceeds $700 million as of June 30 of a fiscal year. We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and the price of our common shares may be more volatile than that of an otherwise comparable company that does not avail itself of the same or similar exemptions. We are a smaller reporting company, and the reduced reporting requirements applicable to smaller reporting companies may make our common shares less attractive to investors. We are a “smaller reporting company” as defined in Rule 12b-2 under the Exchange Act. For as long as we continue to be a smaller reporting company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including reduced financial statement and other financial information disclosure, and reduced disclosure obligations regarding executive compensation in our annual and periodic reports and proxy statements. We will remain a smaller reporting company as long as either (i) the market value of our common shares held by non-affiliates is less than $250 million or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our common shares held by non-affiliates is less than $700 million. Our public float is measured as of the last business day of our most recently completed second fiscal quarter, and annual revenues are as of the most recently completed fiscal year for which audited financial statements are available. We cannot predict if investors will find our common shares less attractive because we may rely on these exemptions. If some investors find our common shares less attractive as a result, there may be a less active trading market for our common shares and our share price may be more volatile than that of an otherwise comparable company that does not avail itself of the same or similar exemptions. We are a BVI business company limited by shares and, the holders of our common shares may have fewer protections as a shareholder of our company, because judicial precedent regarding the rights of shareholders is more limited under BVI law than that under U.S. law. Our corporate affairs are governed by our Amended Memorandum and Articles of Association as amended and restated from time to time, the BVI Business Companies Act (As Revised) (the “BVI Act”) and the common law of the BVI. The rights of shareholders to take legal action against our directors, actions by minority shareholders and the fiduciary responsibilities of our directors under BVI law are to a large extent governed by the common law of the BVI. The common law of the BVI is derived in part from comparatively limited judicial precedent in the BVI as well as from English common law, which has persuasive, but not binding, authority on a court in the BVI. The rights of our shareholders and the fiduciary responsibilities of our directors under BVI law therefore are not as clearly established as they would be under statutes or judicial precedents in some jurisdictions in the United States. In particular, the BVI has a less exhaustive body of securities laws as compared to the United States, and some states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the BVI. There is no statutory recognition in the BVI of judgments obtained in the U.S., although the courts of the BVI will in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits. As a result of all of the above, holders of our common shares may have more difficulty in protecting their interests through actions against our management, directors or controlling shareholders than they would as shareholders of a U.S. company. They may have greater difficulty securing legal advice about the law of the BVI than they would U.S. and state law, and the relatively less developed nature of the BVI’s securities law may leave investors with less certainty about the validity and strength of any claims they believe they may have against us. In addition, other differences between BVI and U.S. law, as well as the terms of our Amended Memorandum and Articles of Association, may result in shareholders having different potential influence than they would under various U.S. state laws with respect to matters such as officer and director actions, mergers 69 Table of Contents and acquisitions, dispositions of assets, takeover efforts, and other corporate decision making. Shareholders in BVI business companies may not be able to initiate shareholder derivative actions, thereby depriving a shareholder of the ability to protect its interests. While statutory provisions do exist in BVI law for derivative actions to be brought in certain circumstances, shareholders in BVI business companies may not have standing to initiate a shareholder derivative action in a federal court of the United States. The circumstances in which any such action may be brought, and the procedures and defenses that may be available in respect to any such action, may result in the rights of shareholders of a BVI business company being more limited than those of shareholders of a company organized in the United States. Accordingly, shareholders may have fewer alternatives available to them if they believe that corporate wrongdoing has occurred. The BVI courts are also unlikely to: (i) recognize or enforce against us judgments of courts in the United States based on certain civil liability provisions of U.S. securities law; or (ii) to impose liabilities against us, in original actions brought in the BVI, based on certain civil liability provisions of U.S. securities laws that are penal in nature or that relate to taxes or similar fiscal or revenue obligations or would be viewed as contrary to BVI public policy or the proceedings pursuant to which judgment was obtained were contrary to natural justice. There is no statutory recognition in the BVI of judgments obtained in the United States. However, the courts of the BVI will in certain circumstances recognize such a foreign judgment and treat it as a cause of action in itself which may be sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that: • the U.S. court issuing the judgment had jurisdiction in the matter and the company either submitted to such jurisdiction or was resident or carrying on business within such jurisdiction and was duly served with process; • the judgment is final and for a liquidated sum; • the judgment given by the U.S. court was not in respect of penalties, taxes, fines or similar fiscal or revenue obligations of the company; • in obtaining judgment there was no fraud on the part of the person in whose favor judgment was given or on the part of the court; • recognition or enforcement of the judgment in the British Virgin Islands would not be contrary to public policy; and • the proceedings pursuant to which judgment was obtained were not contrary to natural justice. The British Virgin Islands courts are unlikely: • to recognize or enforce against the Company, judgments of courts of the U.S. predicated upon the civil liability provisions of the securities law of the U.S.; and • to impose liabilities against the Company, predicated upon the certain civil liability provisions of the securities laws of the U.S. so far as the liabilities imposed by those provisions are penal in nature. The laws of the BVI relating to the protection of minority shareholders differ from those under U.S. law and, in some circumstances, may offer less protection. The BVI Act includes the following statutory remedies which minority shareholders in the company can rely upon: • If the company or a director of the company engages in or proposes to engage in conduct, that contravenes the BVI Act or our Amended Memorandum and Articles of Association, a shareholder may apply to the BVI court for an order directing the company or its director(s) to comply with or restraining the company or a director from engaging in conduct that contravenes the BVI Act or our Amended Memorandum and Articles of Association. • Under the BVI Act, minority shareholders have a statutory right to bring a derivative action in the name of and on behalf of the company in circumstances where the company has a cause of action against its directors. This remedy is available at the discretion of the BVI court which will take a number of factors into account before granting or refusing a leave to proceed to the relevant shareholder, including whether such action is in the interests of the company, the cost of such action and whether there are alternative remedies that the shareholder concerned may rely upon. • A shareholder of the company may bring an action against the company for breach of duty owed to him or her as a shareholder. This would typically be relevant in a situation where a shareholder is aggrieved by the company for breach of an entitlement or right under the company’s Amended Memorandum and Articles of Association. • A shareholder of the company who considers that the affairs of the company have been, are being or likely to be, conducted in a manner that is, or any act or acts of the company have been, or are, likely to be oppressive, unfairly discriminatory, or unfairly prejudicial to him in that capacity, may apply to the BVI court for an order to remedy the situation. Again, this is a discretionary remedy and the BVI court will only award it if they are satisfied that it is just and equitable to do so. • A shareholder may, in certain circumstances, apply for liquidators to be appointed over the affairs of a company under the BVI’s Insolvency Act 2003 (as amended) (the “BVI Insolvency Act”.). Shareholders can 70 Table of Contents also by resolution appoint a liquidator of a BVI business company under the BVI Act if the company is solvent or under the BVI Insolvency Act if the company is insolvent. In addition to the statutory rights outlined above, there are common law rights for the protection of shareholders that may be invoked, largely dependent on English common law. Under the general rule pursuant to English common law known as the rule in Foss v. Harbottle, a court will generally refuse to interfere with the management of a company at the insistence of a minority of its shareholders who express dissatisfaction with the conduct of the company’s affairs by the majority or the Board. However, every shareholder is entitled to have the affairs of the company conducted properly according to law and the constituent documents of the company. As such, if those who control the company have persistently disregarded the requirements of company law or the provisions of the company’s Amended Memorandum and Articles of Association, then the courts will grant relief. Generally, the areas in which the courts will intervene are the following: (1) an act complained of which is outside the scope of the authorized business or is illegal or not capable of ratification by the majority; (2) acts that constitute fraud on the minority where the wrongdoers control the company; (3) acts that infringe on the personal rights of the shareholders, such as the right to vote; and (4) where the company has not complied with provisions requiring approval of the shareholders, which are more limited than the rights afforded minority shareholders under the laws of many states in the United States. Having regard to the above, the protection available to minority shareholders under BVI law may be more limited than under the laws of some jurisdictions in the United States. It may be difficult to enforce a U.S. or foreign judgment against us, our directors and our officers outside the United States, or to assert U.S. securities laws claims outside of the United States. As a BVI business company, it may be difficult for a shareholder to effect service of process within the United States upon us, our directors and officers, or to enforce against us, or them, judgments obtained in U.S. courts, including judgments predicated upon the civil liability provisions of the securities laws of the United States or any state therein. Additionally, it may be difficult to assert U.S. securities law claims in actions originally instituted outside of the United States. Foreign courts may refuse to hear a U.S. securities law claim because foreign courts may not be the most appropriate forums in which to bring such a claim. Even if a foreign court agrees to hear a claim, it may determine that the law of the jurisdiction in which the foreign court resides, and not U.S. law, is applicable to the claim. Further, if U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact, which can be a time-consuming and costly process, and certain matters of procedure would still be governed by the law of the jurisdiction in which the foreign court resides. Accordingly, it may be difficult or impossible for you to bring an action against us in the BVI if you believe your rights under the U.S. securities laws have been infringed. In addition, there is uncertainty as to whether the courts of the BVI would recognize or enforce judgments of U.S. courts against us or such persons predicated upon the civil liability provisions of the securities laws of the U.S. or any state and it is uncertain whether such British Virgin Islands courts would hear original actions brought in the British Virgin Islands against us or such persons predicated upon the securities laws of the U.S. or any state. Changes in tax law, determinations by tax authorities or changes in our effective tax rates may adversely affect our business and financial results. Under current law, we expect to be treated as a non-U.S. corporation for U.S. federal income tax purposes. The tax laws applicable to our business activities, however, are subject to change and uncertain interpretation. Our tax position could be adversely impacted by changes in tax rates, tax laws, tax practice, tax treaties or tax regulations or changes in the interpretation thereof by the tax authorities in jurisdictions in which we do business. Our actual tax rate may vary from our expectation and that variance may be material. A number of factors may increase our future effective tax rates, including: (1) the jurisdictions in which profits are determined to be earned and taxed; (2) the resolution of issues arising from any future tax audits with various tax authorities; (3) changes in the valuation of our deferred tax assets and liabilities; (4) our ability to use tax credit and net operating loss carryforwards to reduce future tax liabilities; and (5) changes in tax laws or the interpretation of such tax laws, and changes in generally accepted accounting principles. We may also become subject to income, withholding or other taxes in jurisdictions by reason of our activities and operations, and it is possible that taxing authorities in such jurisdictions could assert that we are subject to greater taxation than we currently anticipate. Since 2017, the G20/OECD Inclusive Framework has been working on addressing the tax challenges arising from the digitalization of the economy and has proposed a two-pillar tax approach with pillar one referring to the re- allocation of taxing rights, addressing issues such as where tax should be paid and on what basis (i.e., where sustained and significant business is conducted, regardless of a physical presence), and pillar two ensuring a minimum tax to be paid by multinational enterprises. We are unable to predict when and how the Inclusive Framework agreement will be enacted into law in the countries in which we operate, and it is possible that the implementation of the Inclusive Framework agreement, including the global minimum corporate tax rate, could have a material effect on our liability for corporate taxes and our consolidated effective tax rate. 71 Table of Contents If we are or become a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S. holders. If we are or become a passive foreign investment company (“PFIC”) for any taxable year during which a U.S. holder holds our shares, the U.S. holder would be subject to adverse tax consequences regardless of whether we continue to qualify as a PFIC, including ineligibility for any preferred tax rates on capital gains or on actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional reporting requirements. Under the Code, we would be a PFIC for any taxable year in which (1) 75% or more of our gross income consisted of passive income or (2) 50% or more of the average quarterly value of our assets consisted of assets that produce, or are held for the production of, passive income. For purposes of these tests, passive income includes, but is not limited to, dividends, interest, gains from the sale or exchange of investment property and certain rents and royalties. In addition, for purposes of the above calculations and subject to certain exceptions, a non-U.S. corporation that directly or indirectly owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate share of the assets and received directly its proportionate share of the income of such other corporation. Although we believe our common shares should not currently be stock of a PFIC for U.S. federal income tax purposes and do not expect to become a PFIC in the foreseeable future, we cannot provide any assurances regarding our PFIC status for any current or future taxable years. The determination of whether we are a PFIC is a fact- intensive determination made on an annual basis applying principles and methodologies which in some circumstances are unclear and subject to varying interpretation. In particular, the determination of whether we are a PFIC and the characterization of our assets as active or passive may depend in part on (i) our current and intended future business plans which are subject to change, (ii) the application of certain “look-through” rules and (iii) the applicability of the “start-up exception.” Under the start-up exception, a foreign corporation that would otherwise be treated as a PFIC will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if: (A) no predecessor of the corporation was a PFIC; (B) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year; and (C) the corporation is not in fact a PFIC for either of those years. The applicability of the startup exception to us is uncertain and will not be known until after the end of the two taxable years following such startup year. In addition, for our current and future taxable years, the total value of our assets for PFIC testing purposes may fluctuate considerably from time to time, and is dependent on our application (which inherently involves an element of judgment) of the relevant valuation assumptions and methodologies. Under the income test, our status as a PFIC depends on the composition of our income which, in our current and future taxable years, we may not be able to fully control, for example, with respect to income attributed to us from entities owned 25% or more by us. The composition of our income and assets is also affected by how, and how quickly, we spend the cash we raise in any offering. Therefore, we cannot provide any assurance regarding our PFIC status for any past, current or future taxable years. In certain circumstances, a U.S. holder of shares in a PFIC may alleviate some of the adverse tax consequences described above by making a “qualified electing fund” (“QEF”) election to include in income its pro rata share of the corporation’s income on a current basis. However, a U.S. holder may make a QEF election with respect to our common shares only if we agree to furnish such U.S. holder annually with a PFIC annual information statement as specified in the applicable U.S. Treasury Regulations. We currently do not intend to prepare or provide the information that would enable U.S. holders to make a QEF election if we are treated as a PFIC for any taxable year, and U.S. holders of our common shares should assume that a QEF election will not be available. U.S. holders should consult their own tax advisors with respect to the operation of the PFIC rules and related reporting requirements in light of their particular circumstances, including the advisability of making any election that may be available. Mail addressed to us may not reach us in a timely manner. Mail addressed to the Company and received at its registered office will be forwarded unopened to the forwarding address supplied by Company to be dealt with. None of the Company, its directors, officers, advisors or service providers (including the organization which provides registered office services in the BVI) will bear any responsibility for any delay howsoever caused in mail reaching the forwarding address. Such risk will be borne solely by the Company’s shareholders. Our Amended Memorandum and Articles of Association provide that unless we consent in writing to the selection of an alternative forum, the courts of the British Virgin Islands shall, with certain limited exceptions, be the sole and exclusive forum for certain disputes between us and our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees. Our Amended Memorandum and Articles of Association provide that unless we consent in writing to the selection of an alternative forum, the courts of the British Virgin Islands shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, 72 Table of Contents officer or other employee of the Company to the Company or the Company’s members, (iii) any action asserting a claim arising pursuant to any provision of British Virgin Islands law or the Amended Memorandum and Articles of Association, or (iv) any action asserting a claim against the Company governed by the internal affairs doctrine, and that each shareholder consents to the exclusive jurisdiction of the courts of the British Virgin Islands over all such claims or disputes. Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over actions brought under the Securities Act or the rules and regulations promulgated thereunder. Furthermore, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the forum selection provision in our Amended Memorandum and Articles of Association will not apply to actions or suits brought to enforce any liability or duty created by the Securities Act, Exchange Act or any claim for which the federal district courts of the United States of America are, as a matter of the laws of the United States of America, the sole and exclusive forum for determination of such a claim. This choice of forum provision may increase a shareholder’s cost, impose additional litigation costs and limit the shareholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees, although our shareholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder and may therefore bring certain claims in another appropriate forum. Any person or entity purchasing or otherwise acquiring any of our shares or other securities, whether by transfer, sale, operation of law or otherwise, shall be deemed to have notice of and have irrevocably agreed and consented to these provisions. It is possible that a court could find such a choice of forum provision to be inapplicable or unenforceable, and if a court were to find this provision in our Amended Memorandum and Articles of Association to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could have an adverse effect on our business, results of operations and financial condition. Because our common shares have only traded on the public market for a limited period of time, the market price and trading volume of our common shares may be volatile. Prior to the Distribution, there had not been a regular-way trading market for our common shares. We cannot predict the extent to which investors’ interest will lead to a liquid trading market or whether the market price of our common shares will be volatile. The market price of our common shares could fluctuate significantly for many reasons, including in response to the risk factors listed in this Annual Report on Form 10-K or for reasons unrelated to our specific performance, such as reports by industry analysts, investor perceptions, or negative developments for our customers, competitors or suppliers, as well as general economic and industry conditions. Our historical financial results as a part of Former Parent may not be representative of our results as a separate, stand-alone company. The historical financial information we have included in this Annual Report on Form 10-K has been derived from the combined financial statements and accounting records of Former Parent and does not necessarily reflect what our financial position, results of operations or cash flows would have been had we been a separate, stand-alone company during the periods presented. The historical costs and expenses reflected in our combined financial statements include an allocation for certain corporate functions historically provided by Former Parent, including general corporate expenses and employee benefits and incentives. These allocations were based on what we and Former Parent considered to be reasonable reflections of the historical utilization levels of these services required in support of our business. The historical information does not necessarily indicate what our results of operations, financial position, cash flows or costs and expenses will be in the future. We have incurred, and expect to continue to incur, material costs and expenses as a result of our separation from Former Parent. We have incurred, and will expect to continue to incur, costs and expenses greater than those we previously incurred while part of Former Parent as a result of our separation from Former Parent. These increased costs and expenses arise from various factors, including financial reporting and costs associated with complying with federal securities laws (including compliance with the Sarbanes-Oxley Act). In addition, we have increased corporate and administrative costs and expenses compared to those we incurred while part of Former Parent, even though we are now a smaller, stand-alone company. These costs may be material to our business. If we are unable to satisfy the requirements of Section 404 of the Sarbanes-Oxley Act, or our internal control over financial reporting is not effective, the reliability of our financial statements may be questioned and our share price may suffer. Section 404 of the Sarbanes-Oxley Act requires any company subject to the reporting requirements of the U.S. securities laws to do a comprehensive evaluation of its and its consolidated subsidiaries’ internal control over financial reporting. To comply with this statute, we may eventually be required to document and test our internal control procedures, our management will be required to assess and issue a report concerning our internal control over financial reporting, and our 73 Table of Contents independent auditors will be required to issue an opinion on the Company’s internal controls over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management may identify material weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by the Sarbanes-Oxley Act. If our management cannot favorably assess the effectiveness of our internal control over financial reporting or our auditors identify material weaknesses in our internal controls, investor confidence in our financial results may weaken, and our share price may suffer.

This number of holders of record also does not include shareholders whose shares may be held in trust by other entities. Dividend Policy We have never declared or paid dividends on our share capital. We do not expect to pay any cash dividends on our common shares in the foreseeable future. All decisions regarding the payment of dividends will be made by our Board of Directors from time to time in accordance with applicable law. Securities Authorized for Issuance Under Equity Compensation Plans See Part III, Item 12 "Security Ownership of Certain Beneficial Owners and Management and Related Shareholder Matters" of this report. Issuer Purchases of Equity Securities We did not purchase any of our registered equity securities during the period covered by this report. Use of Proceeds from Registered Securities In October 2022, we commenced a public offering of 25,000,000 of our common shares at a price of $10.50 per share, pursuant to a registration statement on Form S-1 filed with the SEC (the "S-1"). The S-1 was declared 75 Table of Contents effective by the SEC on October 20, 2022. We also granted the underwriters a 30-day option to purchase up to an additional 3,750,000 common shares. On October 25, 2022, we closed the offering, including a full exercise of the underwriters' option to purchase additional shares. The net proceeds raised in the offering, after deducting underwriting discounts and expenses of the offering payable by Biohaven, were approximately $282,804. There has been no material change in the planned use of proceeds from our initial public offering from that described in the final prospectus filed with the SEC on October 20, 2022. During the period from the closing of the offering to December 31, 2022, we used the proceeds primarily for general corporate purposes, including funding the continued development of our clinical programs and research and development operations as well as costs associated with operating as a public company.

Management's Discussion and Analysis of Financial Condition and Results of Operations inhibition platforms, preclinical product candidates, and certain corporate infrastructure owned by Former Parent. You should read the following discussion and analysis of our On October 3, 2022, the Former Parent completed the financial condition and results of operations together with our financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K, or this Annual Report. In addition to historical information, this discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors. We discuss factors that we believe could cause or contribute to these differences below and elsewhere in this report, including those set forth under Item 1A. "Risk Factors" and under "Cautionary Note Regarding Forward-Looking Statements" in this Annual Report. Overview We are a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life- changing therapies for people with debilitating neurological and neuropsychiatric diseases, including rare disorders. Our experienced management team brings with it a track record of delivering new drug approvals for products for diseases such as migraine, depression, bipolar and schizophrenia. We are advancing a pipeline of therapies for diseases with little or no treatment options, leveraging our proven drug development capabilities and proprietary platforms, including Kv7 ion channel modulation for epilepsy and neuronal hyperexcitability, glutamate modulation for OCD and SCA, myostatin inhibition for neuromuscular diseases, and brain-penetrant TYK2/JAK1 inhibition for immune-mediated brain disorders. Our portfolio of early- and late- stage product candidates also includes discovery research programs focused on TRPM3 channel activation for neuropathic pain, CD-38 antibody recruiting, bispecific molecules for multiple myeloma, ADCs, and extracellular target degrader platform technology (MoDE™) with potential application in neurological disorders, cancer, and autoimmune diseases. We are advancing our broad and diverse pipeline, across early and late stage development, including three Phase 3 clinical programs. We have built a highly experienced team of senior leaders and neuroscience drug developers who combine a nimble, results-driven biotech mindset with capabilities in drug discovery and development. In addition, we have several preclinical assets in our early discovery program, targeting indications in neuroscience and immunology. Separation from Biohaven Pharmaceutical Holding Company Ltd. On May 9, 2022, the Board of Directors of the Former Parent approved and directed Former Parent’s management to effect the spin- off of the Kv7 ion channel activators, glutamate modulation and myostatin Distribution to holders of its common shares of all of the outstanding common shares of Biohaven Ltd. and the spin-off of Biohaven from the Former Parent. Each holder of Former Parent common shares received one common share of Biohaven for every two the Former Parent common shares held of record as of the close of business, New York City time, on September 26, 2022. To implement the Spin-Off, the Former Parent transferred the related license agreements, intellectual property and the Former Parent’s corporate infrastructure, including certain non-commercial employee agreements, share-based awards and other corporate agreements to Biohaven Ltd. Collectively, we refer to the Distribution and Spin-Off throughout this Annual Report on Form 10-K as the "Separation." In the Distribution, an aggregate of 35,840,459 common shares of the Company were issued. The aggregate number of common shares issued in connection with the Distribution did not include 2,611,392 common shares issued in connection with Former Parent stock options that were exercised on October 3, 2022 and 924,093 common shares issued in connection with Former Parent restricted stock units that vested on October 3, 2022. Biohaven Ltd. is a British Virgin Islands ("BVI") corporation and was a wholly owned subsidiary of Biohaven Pharmaceutical Holding Company Ltd. prior to the Separation. Prior to the Separation, the historical combined financial statements of the Company prior to the distribution were prepared on a stand-alone basis and are derived from the consolidated financial statements and accounting records of Biohaven Pharmaceutical Holding Company Ltd. The financial statements for all periods presented, including the historical results of the Company prior to October 3, 2022, are now referred to as "Consolidated Financial Statements." Our financial statements are presented in conformity with generally accepted accounting principles in the United States ("GAAP"). The financial position, results of operations and cash flows of the Company historically operated as part of Biohaven Pharmaceutical Holding Company Ltd.’s financial position, results of operations and cash flows up until the Distribution. These historical combined financial statements may not be indicative of the future performance of the Company and do not necessarily reflect what our consolidated results of operations, financial condition and cash flows would have been had we operated as a separate, publicly traded company during the periods presented. Where we describe historical business activities in this Annual Report on Form 10-K, we do so as if these 77 Table of Contents transfers had already occurred and the Former Parent's activities related to such assets and liabilities had been performed by Biohaven Ltd. Refer to Note 1, "Nature of the Business and Basis of Presentation", of the Notes to the Consolidated Financial Statements appearing elsewhere in this Annual Report on Form 10-K for further discussion of the underlying basis used to prepare the consolidated financial statements. Transition from the Former Parent and Costs to Operate as an Independent Company The consolidated financial statements reflect the operating results and financial position of the Company as it was operated by the Former Parent prior to the Separation, rather than as an independent company. We have incurred and will continue to incur ongoing operating expenses to operate as an independent company. These costs will include the cost of various corporate headquarters functions, information technology-related costs and costs to operate stand-alone accounting, legal and other administrative functions. We will also incur non-recurring expenses and non-recurring capital expenditures. As an independent company, our information technology operating costs may be higher than the costs allocated in the historical combined financial statements. It is not practicable to estimate the costs that would have been Clinical-Stage Milestones Our clinical-stage milestones include the following: incurred in each of the periods presented in the historical combined financial statements for the functions described above. Actual costs that would have been incurred if we operated as a stand-alone company during these periods would have depended on various factors, including the chosen organizational structure, what corporate functions the Company might have performed directly or outsourced and strategic decisions the Company might have made in areas such as executive management, legal and other professional services, and certain corporate overhead functions. During the transition from the Former Parent, we may incur non-recurring expenses to expand our infrastructure. Transactions with the Former Parent We have entered into a Distribution Agreement and various agreements relating to transition services, licenses and certain other matters with the Former Parent. These agreements govern our relationship with the Former Parent and include the allocation of employee benefits, taxes and certain other liabilities and obligations attributable to periods prior to, at and after the Separation. For additional information regarding these agreements, see Note 14, "Related Party Transactions," of the Notes to the Consolidated Financial Statements appearing elsewhere in this Annual Report on Form 10-K.

The acquisition of the Kv7 channel targeting platform adds the latest advances in ion-channel modulation to our growing neuroscience portfolio. BHV-7000 (formerly known as KB-3061), the lead asset from the Kv7 platform is an activator of Kv7.2/Kv7.3, a key ion channel involved in neuronal signaling and in regulating the hyperexcitable state in epilepsy. In June 2022, our Clinical Trial Application for BHV-7000 was approved by Health Canada, and in July we began clinical development. Dosing has been completed in our Phase 1 SAD/MAD study with BHV-7000 and, in January 2023, the Company reported preliminary safety, tolerability and pharmacokinetic ("PK") data. In the study, single doses up to 100 mg and multiple doses up to 40 mg daily for 15 days were safe and well-tolerated. In the pooled, blinded adverse events from the SAD and MAD cohorts occurring in more than 1 subject, mild headache was the most common adverse event reported across all groups (including BHV-7000 and placebo), and a lack of CNS adverse events were observed. Most adverse events were mild and resolved spontaneously. No serious or severe adverse events and no dose limiting toxicities were reported. With respect to preliminary PK results, the Company exceeded target concentrations for efficacy based on the preclinical maximal electroshock ("MES") model, which is clinically validated and predictive of target concentration ranges in humans. Epilepsy Epilepsy is the initial disease we are targeting with activators from our Kv7 platform. Epilepsy affects approximately 3.5 million Americans, or more than 1.2% of adults and 0.6% of children in the U.S., and more than 50 million patients worldwide, according to the World Health Organization (“WHO”). It is the fourth most common neurological disorder, and many patients struggle to achieve freedom from seizures, with more than one third of patients requiring two or more medications to manage their epilepsy. While the use of anti- seizure medications is often accompanied by dose-limiting side effects, our clinical candidate BHV-7000 is specifically designed to target subtypes of Kv7 potassium channels without engagement of GABA A receptors. The lack of GABA -R activity potentially gives BHV-7000 a wide therapeutic window which we expect to result in an improved side effect profile, limiting the somnolence and fatigue often seen in patients receiving anti-seizure medications. By adding BHV-7000 to our pipeline, we aim to bring this potassium channel modulator as a potential solution to patients with epilepsy who remain uncontrolled on their current regimens. If our Phase 1 study with BHV-7000 is A successfully completed, we expect to initiate at least one pivotal trial in patients with epilepsy in the second half of 2023. KCNQ2 Developmental Epileptic Encephalopathy We are currently exploring BHV-7000 as a potential treatment for KCNQ2 developmental epileptic encephalopathy ("KCNQ2-DEE"), a rare pediatric epileptic encephalopathy first described in 2012 resulting from dominant-negative mutations in the KCNQ2 gene. BHV-7000 has been granted Rare Pediatric Disease Designation by the FDA for the treatment of KCNQ2-DEE. Mood Disorders Approximately 1 in 5 adults in the US are living with neuropsychiatric illnesses that are, in turn, associated with inadequate treatment, poor quality of life, disability, and considerable direct and indirect costs. There is significant unmet need for novel and effective therapeutic options that are not limited by long latency periods to clinical effects, low response rates, and significant risks and side effects. Increasing evidence from animal models and clinical trials now suggests that Kv7.2/7.3 targeting drugs offer the potential to treat a spectrum of these neuropsychiatric diseases including, but not limited to, mood disorders, such as major depressive disorder, bipolar disorder and anxiety. We plan to advance BHV-7000 as a potential treatment for patients with bipolar disorder and intend to start a clinical trial targeting this indication by the end of 2023. Neuropathic Pain Neuropathic pain, as defined by the International Association for the Study of Pain, is pain caused by a lesion or disease of the somatosensory nervous system and includes a collection of heterogeneous conditions that are often chronic and debilitating and for which long term therapy is difficult. In the United States, over 30 million adults are estimated to be living with neuropathic pain. Previous studies have demonstrated the efficacy of Kv7 targeting drugs in clinical trials for pain indications and in animal models. Selective Kv7 potassium channel activators represent a promising new approach in the development of non-opioid therapeutic options for neuropathic pain. In addition to leveraging reduced abuse and addiction risk potential of potassium channel activators, our Kv7 potassium channel platform addresses the complexities of channel subtype physiology through targeted pharmacology to overcome the limitations inherent in unbiased Kv7 activators and is intended to deliver a well-tolerated, highly effective, non-opioid treatment for neuropathic pain. We are currently evaluating the activity of BHV-7000 and other compounds from our proprietary 79 Table of Contents series of selective Kv7.2/7.3 activators in multiple preclinical models of neuropathic pain. BHV-7010 BHV-7010 is being developed as a next generation Kv7.2/7.3 activator with improved selectivity over Kv7.4 and differentiated ADME properties that provide flexibility for the treatment of different neurological diseases. The IND is expected to be submitted in the second half of 2023. TYK2/JAK1 Glutamate The most advanced product candidate from our glutamate receptor antagonist platform is troriluzole (previously referred to as trigriluzole and BHV-4157), which is in multiple Phase 3 trials. Other product candidates include BHV-5500 (lanicemine), which is an antagonist of the glutamate N-methyl-D-aspartate (“NMDA”) receptor, and BHV-5000, which is a prodrug of lanicemine. Troriluzole Spinocerebellar Ataxia Agreement with Hangzhou Highlightll Pharmaceutical Co. Ltd. In May 2022, the Company announced top-line results from the In March 2023, we entered into an exclusive, worldwide (excluding People’s Republic of China and its territories and possessions) license agreement with Highlightll, whereby we obtained the right to research, develop, manufacture and commercialize Highlightll’s brain penetrant dual TYK2/JAK1 inhibitor program. As partial consideration for the Highlightll Agreement, we are obligated to pay Highlightll a cash payment of $10,000 and common shares valued at approximately $10,000 as of the agreement execution, upon the completion of certain post-closing activities. See Note 15, "Subsequent Events," for further detail on the Highlightll Agreement. BHV-8000 Dysregulation of the immune system has been implicated in several neurodegenerative and neuroinflammatory disorders including Parkinson's Disease, Multiple Sclerosis, Alzheimer's Disease, Amyotrophic Lateral Sclerosis and Autoimmune Encephalitis. Over- active immune cells and microglia driving chronic neuroinflammation results in release of cytokines with activation of leukocytes and is thought to contribute to neuronal injury, death, gliosis, and demyelination. The TYK2 and JAK1 signal transduction pathways mediate highly complementary immune and inflammatory signaling events. Targeted, small-molecule therapies that inhibit TYK2 or JAK kinases have separately demonstrated robust efficacy in autoimmune, dermatologic and gastrointestinal disorders. TYK2 is a validated immune target as evidenced by a recent peripheral program that gained FDA approval, and there are multiple additional peripheral non- CNS programs in clinical development. Brain penetrant inhibitors of TYK2/JAK1 have the potential to bring this validated immune target to brain disorders. There are currently no brain penetrant, selective, dual TYK2/JAK1 inhibitors approved for brain disorders. We expect to advance BHV-8000 (previously TLL-041) into a Phase 1 study in 2023. The Company is evaluating and has not yet finalized potential clinical trial designs, including size and primary and secondary endpoints. Phase 3 clinical trial evaluating the efficacy and safety of its investigational therapy, troriluzole, in patients with SCA. The primary endpoint, change from baseline to Week 48 on the modified functional Scale for the Assessment and Rating of Ataxia (f-SARA), did not reach statistical significance in the overall SCA population as there was less than expected disease progression over the course of the study. In the overall study population (N=213), the troriluzole and placebo groups each had mean baseline scores of 4.9 on the f-SARA and the two groups showed minimal change at the 48-week endpoint with f-SARA scores of 5.1 and 5.2, respectively (p=0.76). Post hoc analysis of efficacy measures by genotype suggests a treatment effect in patients with the SCA Type 3 (“SCA3”) genotype, which represents the most common form of SCA and accounted for 41% of the study population. In the SCA3 subgroup, troriluzole showed a numerical treatment benefit on the change in f-SARA score from baseline to Week 48 compared to placebo (least squares (“LS”) mean change difference -0.55, nominal p-value = 0.053, 95% CI: -1.12, 0.01). SCA patients treated with troriluzole showed minimal disease progression over the study period. Further, in patients in the SCA3 subgroup with mild disease severity at baseline, defined as those who were able to walk without assistance at baseline (i.e., f-SARA Gait Item score = 1), troriluzole demonstrated a greater numerical treatment benefit on the change in f-SARA score from baseline to Week 48 compared to placebo (LS mean change difference -0.71, nominal p- value = 0.031, 95% CI: -1.36, -0.07). Notably, the f-SARA is a novel, 16-point scale developed in collaboration with FDA as the primary outcome measure for this trial; the scale was designed to limit subjectivity of the scale and focus on functional aspects of the disease so that significant changes would be considered clinically meaningful. Across all SCA genotypes, and SCA3 specifically, patient reported falls, as measured by adverse events, reveal reductions of fall risk in the troriluzole group compared to the placebo. The risk reduction of falls in the troriluzole group combined with the progression of f-SARA scores in the untreated SCA3 group compared to SCA3 patients on troriluzole demonstrates that SCA3 patients 80 Table of Contents experienced a clinically meaningful improvement in ataxia symptoms on troriluzole treatment. Given these findings and the debilitating nature of SCA, we intend to interact with the FDA and/or European Medicines Agency ("EMA") in the first half of 2023. We have not yet decided on the format of such a regulatory interaction but we could seek advice through various formal or informal interactions with regulatory agencies or we could choose to submit an NDA if we believe that is warranted from the results of our ongoing post-hoc analyses. There are currently no FDA-approved medications for the treatment of SCA or any other cerebellar ataxia, and treatment is supportive. In general, multidisciplinary care provides supportive measures and the goal of this treatment is to improve quality of life and survival. Obsessive Compulsive Disorder We commenced a Phase 2/3 double-blind, randomized, controlled trial to assess the efficacy of troriluzole in adults with OCD in December 2017. The Phase 2/3 study results were announced in June 2020. Troriluzole 200 mg administered once daily as adjunctive therapy in OCD patients with inadequate response to standard of care treatment showed consistent numerical improvement over placebo on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) at all study timepoints (weeks 4 to 12) but did not meet the primary outcome measure at week 12. Troriluzole treated subjects (n = 111) had a mean Y-BOCS improvement of -3.4 points from baseline versus -2.9 for placebo-treated (n = 115) subjects [difference -0.5 and p-value = 0.451] at week 4, -5.1 points (n = 96) versus -3.6 for placebo-treated (n = 108) subjects [difference -1.5 and p-value = 0.041] at week 8, and -5.9 points (n = 99) versus -4.9 for placebo-treated (n = 102) subjects [difference -1.0 and p-value = 0.220] at week 12. Troriluzole’s safety profile was generally consistent with past clinical trial experience with its active metabolite, riluzole. Treatment emergent adverse events (“TEAE”s) were mostly reported to be mild in intensity. TEAEs that occurred in at least 5% of patients in the troriluzole group, and more frequently in the troriluzole group than in the placebo group, were headache, dizziness, fatigue, somnolence, nausea and nasopharyngitis. Given the strong signal in the Phase 2/3 proof of concept study and after receiving feedback from the FDA in an End of Phase 2 meeting, in December 2020 we initiated enrollment in a Phase 3 program. The Phase 3 program will have an estimated total enrollment of 1,300 participants with a primary endpoint of change from baseline on the Y-BOCS total score at week 4, 8 and 10. The two Phase 3 randomized, double-blind, placebo-controlled trials that make-up our Phase 3 program for OCD are currently ongoing with enrollment expected to be completed in 2023. Glioblastoma In December 2021, the Global Coalition for Adaptive Research ("GCAR") selected troriluzole for evaluation in Glioblastoma Adaptive Global Innovative Learning Environment - NCT03970447 ("GBM AGILE"). GBM AGILE is a revolutionary patient-centered, adaptive platform trial for registration that tests multiple therapies for patients with newly-diagnosed and recurrent glioblastoma ("GBM"), the most fatal form of brain cancer. Troriluzole will be evaluated in all patient subgroups of the trial which include newly-diagnosed methylated MGMT, newly-diagnosed unmethylated MGMT, and recurrent GBM. Troriluzole was selected for inclusion in GBM AGILE based on compelling evidence showing deregulation of glutamate in GBM. The therapeutic potential of troriluzole in GBM and other oncology indications is supported by several recent clinical and translational research studies conducted with troriluzole and its active moiety. In July 2022, the Company and GCAR announced that enrollment has commenced in GBM AGILE for the evaluation of troriluzole. Lanicemine We are developing BHV-5500 (lanicemine), a low-trapping NMDA receptor antagonist. One potential target indication is neuropathic pain, potentially including Complex Regional Pain Syndrome (“CRPS”). CRPS is a rare, chronic pain condition typically affecting limbs and triggered by traumatic injury. Accompanying symptoms also include chronic inflammation and reduced mobility in the affected areas. Other disorders of interest include post-herpetic neuralgia and diabetic peripheral neuropathy. We acquired worldwide rights to BHV-5500 and its oral prodrug BHV-5000 under an exclusive license agreement with AstraZeneca AB in October 2016. Current work is focused on formulation development. Myostatin Platform Taldefgrobep Alfa (BHV-2000) In February 2022, we announced that we entered into a worldwide license agreement with BMS for the development and commercialization rights to taldefgrobep alfa (also known as BMS- 986089 and now referred to as BHV-2000), a novel, Phase 3-ready anti-myostatin adnectin. Myostatin is a natural protein that limits skeletal muscle growth, an important process in healthy muscular development. However, in patients with neuromuscular diseases, active myostatin can critically limit the growth needed to achieve developmental and functional milestones. Myostatin inhibition is a promising therapeutic strategy for enhancing muscle mass and strength in a range of pediatric and adult neuromuscular conditions. Taldefgrobep is a muscle-targeted treatment for neuromuscular disease and offers the opportunity for combination therapy. In July 2022, we commenced enrollment in a Phase 3 clinical trial of BHV-2000 assessing the efficacy and safety of taldefgrobep alfa in Spinal Muscular Atrophy ("SMA"). SMA is a rare, progressively 81 Table of Contents debilitating motor neuron disease in which development and growth of muscle mass are compromised, resulting in progressive weakness and muscle atrophy, reduced motor function, impaired quality of life and often death. The Phase 3 placebo-controlled, double-blind trial is designed to evaluate the efficacy and safety of taldefgrobep as an adjunctive therapy for participants who are already taking a stable dose of nusinersen or risdiplam or have a history of treatment with onasemnogene abeparvovec-xioi, compared to placebo. The study is not restricted nor limited to patients based on ambulatory status or classification of SMA. We expect to enroll approximately 180 patients in this randomized, double-blind, placebo-controlled global trial. In February 2023, we received Fast Track designation from the FDA for taldefgrobep alfa for the treatment of SMA. In December 2022, we received orphan drug designation from the FDA for taldefgrobep in the treatment of SMA. CD-38 BHV-1100 In the fourth quarter of 2021, we initiated a Phase 1a/1b trial in multiple myeloma patients using our antibody recruiting molecule BHV- 1100 in combination with autologous cytokine induced memory-like natural killer cells and immune globulin to target and kill multiple myeloma cells expressing the cell surface protein CD38. BHV-1100 is the lead clinical asset from Biohaven’s Antibody Recruiting Molecule ("ARM™") Platform developed from a strategic alliance with PeptiDream Inc. (TYO: 4587). This open-label single center Phase 1a/1b study will assess the safety and tolerability as well as exploratory efficacy endpoints in newly diagnosed multiple myeloma patients who have tested positive for minimal residual disease (“MRD+”) in first or second remission prior to autologous stem cell transplant (“ASCT”). We plan to enroll 30 newly diagnosed multiple myeloma patients. The primary outcome measures are dose limiting toxicities following combination product administration (time frame: 100 days post-combination product administration) and incidence and severity of side effects related to the combination product (time frame: 90 to 100 days post-combination product administration). MPO Platform Verdiperstat We were developing verdiperstat (previously BHV-3241), an oral myeloperoxidase inhibitor for the treatment of neurodegenerative diseases. One potential target indication is Amyotrophic Lateral Sclerosis ("ALS"). In September 2019, we announced that verdiperstat was selected to be studied in the Phase 3 HEALEY ALS Platform Trial, which is being conducted by the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital in collaboration with the Northeast ALS Consortium clinical trial network. Promising investigational drugs were chosen for the HEALEY ALS Platform Trial through a competitive process, with the Healey Center providing partial financial support to successful applicants. The Phase 3 HEALEY ALS Platform Trial of verdiperstat began enrollment in July 2020. Enrollment in the trial was completed in November 2021. In September 2022, the Company announced that verdiperstat did not statistically differentiate from placebo on the prespecified primary efficacy outcome, disease progression measured by the ALS Functional Rating Scale-Revised and survival, nor the key secondary efficacy measures during the 24-week study period. Initial analysis of safety data was consistent with the overall profile of verdiperstat from prior clinical trial experience. Additional analyses are ongoing, and complete study results will be presented at an upcoming scientific meeting. At this time, we do not have plans to pursue any additional clinical trials evaluating verdiperstat in ALS and we may evaluate its potential in other disease indications. Verdiperstat was progressed through Phase 2 clinical trials by AstraZeneca. Seven clinical studies have been completed by AstraZeneca, including four Phase 1 studies in healthy subjects, two Phase 2a studies in subjects with Parkinson’s disease, and one Phase 2b study in subjects with MSA. We have entered into an exclusive license agreement with AstraZeneca for the product candidate. Discovery Research Kleo Pharmaceuticals, Inc. and Biohaven Labs In January 2021, we acquired the remaining approximately 58% of Kleo Pharmaceuticals, Inc. ("Kleo") that we did not previously own. We have assumed Kleo's laboratory facilities located in Science Park in New Haven, Connecticut. We are continuing several existing Kleo discovery partnerships, including one with PeptiDream for the development of immuno-oncology therapeutics (See Note 6). TDP-43 Agreement with Fox Chase Chemical Diversity Center, Inc. In May 2019, we entered into an agreement with Fox Chase Chemical Diversity Center Inc. (“FCCDC”) for FCCDC’s TDP-43 assets (the “FCCDC Agreement”). The FCCDC Agreement provides us with a plan and goal to identify one or more new chemical entity candidates for preclinical development for eventual clinical evaluation for the treatment of one or more TDP-43 proteinopathies. In connection with the FCCDC Agreement, Biohaven and FCCDC have established a TDP-43 Research Plan that provides for certain milestones to be achieved by FCCDC, and milestone payments to be made by us. UC1MT Agreement with University of Connecticut 82 Table of Contents In October 2018, we entered into an exclusive, worldwide option and license agreement (the "UConn Agreement") with the University of Connecticut ("UConn") for the development and commercialization rights to UC1MT, a therapeutic antibody targeting extracellular metallothionein. Under this agreement, we had the option to acquire an exclusive, worldwide license to UC1MT and its underlying patents to develop and commercialize throughout the world in all human indications (the "UConn Option"). In September 2022, the Company exercised the UConn Option in exchange for a payment of $0.4 million. Under the agreement, UConn will be entitled to milestone payments upon the achievement of specified regulatory and commercial milestones, and royalties of a low single-digit percentage of net sales of licensed products. Artizan Biosciences, Inc. In December 2020, we entered into an Option and License Agreement (the "2020 Artizan Agreement") with Artizan Biosciences Inc. ("Artizan"), a biotechnology company focused on addressing inflammatory diseases involving the human intestinal microbiota. Pursuant to the 2020 Artizan Agreement, we acquired an option to obtain a royalty-based license from Artizan to manufacture, use and commercialize certain products. Artizan will use the proceeds to continue advancing the preclinical research and development of its lead program for inflammatory bowel disease as well as to explore additional disease targets. In June 2022, we and Artizan executed a non-binding indication of interest which described terms under which we and Artizan would amend the 2020 Artizan Agreement to eliminate certain milestone payments required by us in exchange for limiting our option to the selection of the first licensed product. In the fourth quarter of 2022, Artizan was unable to secure additional financing to support it's ongoing operations, and, as a result, began reviewing strategic options for the sale of its assets, and secured a small bridge financing to fund operations during the strategic review. In January, Artizan severed substantially all of its employees and halted the PD program. Although Artizan anticipates bringing the inflammatory bowel disease program to the clinic in 2023, its ability to do so will be dependent on its access to adequate funding. Reliant Glycosciences, LLC In July 2021, we entered into a development and license agreement with Reliant Glycosciences, LLC ("Reliant") for collaboration on a program with Biohaven Labs’ multifunctional molecules to develop and commercialize conjugated antibodies for therapeutic uses relating to IgA nephropathy and treatment of other diseases and conditions. Under the Agreement, Reliant was entitled to an upfront share payment and will be eligible to receive development milestone payments and royalties of net sales of licensed products. TRPM3 Antagonists In January 2022, we entered into an Exclusive License and Research Collaboration Agreement with Katholieke Universiteit Leuven ("KU Leuven") to develop and commercialize TRPM3 antagonists to address the growing proportion of people worldwide living with chronic pain disorders (the "KU Leuven Agreement"). The TRPM3 antagonist platform was discovered at the Centre for Drug Design and Discovery and the Laboratory of Ion Channel Research at KU Leuven. Under the KU Leuven Agreement,we receive exclusive global rights to develop, manufacture and commercialize KU Leuven's portfolio of small- molecule TRPM3 antagonists. The portfolio includes the lead candidate, henceforth known as BHV-2100, which is being evaluated in preclinical pain models and will be the first to advance towards Phase 1 studies. We expect to submit an IND application for BHV-2100 with the FDA in the second half of 2023. We will support further basic and translational research at KU Leuven on the role of TRPM3 in pain and other disorders. The Company is evaluating and has not yet finalized potential clinical trial designs, including size and primary and secondary endpoints. MoDE Platform In January 2021, we entered into a worldwide, exclusive license agreement with Yale University for the development and commercialization of a novel Molecular Degrader of Extracellular Protein ("MoDE") platform (the "Yale MoDE Agreement"). Under the license agreement, we acquired exclusive, worldwide rights to Yale University's intellectual property directed to its MoDE platform. The platform pertains to the clearance of disease-causing protein and other biomolecules by targeting them for lysosomal degradation using multi- functional molecules. In October 2022, we announced advancements in the development of our MoDE extracellular target degrader platform technology licensed from Yale University for various disease indications, including, but not limited to, neurological disorders, cancer, infectious and autoimmune diseases. Biohaven made further innovations in this ground-breaking technology with new patent applications covering additional targets and functionality. The Company evaluated the effect of a single dose of immunoglobulin gamma ("IgG") degrader, BHV-1300, in cynomolgus monkeys. The Company reported 75% reduction of IgG levels from baseline and noted the observation occurred in three days; the data in this pre-clinical study compares favorably to standard of care therapy efgartigimod, where reduction of IgG levels with efgartigimod was observed to be 50% and had taken 5-7 days. The Company expects to submit an IND application for BHV-1300 with the FDA in the second half of 2023. The Company presented preclinical data with a second MoDE targeting galactose deficient IgA ("Gd- 83 Table of Contents IgA"), which is believed to play a pathogenic role in IgA Nephropathy. Specific removal of pathogenic Gd-IgA with preservation of normal IgA potentially permits disease remission without incurring an infection risk. The Company shared preliminary data demonstrating the chimeric antibody-ASGPR ligand conjugate specifically mediated endocytosis of Gd-IgA, as opposed to normal IgA, in an endocytosis assay with HepG2 cells. Components of Our Results of Operations Revenue To date, the we have not generated any revenue from product sales and we do not expect to generate any revenue from the sale of products in the near future. If our development efforts for our product candidates are successful and result in regulatory approval or additional license agreements with third parties, then we may generate revenue in the future from product sales. Operating Expenses Research and Development Expenses Research and development ("R&D") expenses consist primarily of costs incurred in connection with the development of our product candidates. We expense research and development costs as incurred. These expenses include: • expenses incurred under agreements with contract research organizations (“CROs”) or contract manufacturing organizations (“CMOs”), as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services; • manufacturing scale-up expenses and the cost of acquiring and manufacturing preclinical and clinical trial materials and commercial materials, including manufacturing validation batches; • • • • • employee-related expenses, including salaries, benefits, travel and non-cash share-based compensation expense for employees engaged in research and development functions; costs related to compliance with regulatory requirements; development milestone payments incurred prior to regulatory approval of the product candidate; rent and operating expenses incurred for leased lab facilities and equipment; and payments made in cash, equity securities or other forms of consideration under third-party licensing or other agreements prior to regulatory approval of the product candidate. We recognize external development costs based on an evaluation of the progress to completion of specific tasks using estimates from our clinical personnel or information provided to us by our service providers. Our external direct research and development expenses are tracked on a program-by-program basis for our product candidates and consist primarily of external costs, such as fees paid to outside consultants, CROs, CMOs, and central laboratories in connection with our preclinical development, process development, manufacturing and clinical development activities. Our direct research and development expenses by program also include fees and certain development milestones incurred under license agreements. We do not allocate employee costs, or other indirect costs, to specific programs because these costs are deployed across multiple programs and, as such, are not separately classified. We use internal resources primarily to oversee the research and development as well as for managing our preclinical development, process development, manufacturing and clinical development activities. Many employees work across multiple programs, and we do not track personnel costs by program. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will remain significant over the next several years as we increase personnel costs, conduct late-stage clinical trials, and prepare regulatory filings for our product candidates. We also expect to incur additional expenses related to milestone and royalty payments payable to third parties with whom we have entered into license agreements to acquire the rights to our product candidates. The successful development and commercialization of our product candidates is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of any of our product candidates or when, if ever, material net cash inflows may commence from any of our product candidates. This uncertainty is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of: the scope, progress, outcome and costs of our preclinical development activities, clinical trials and other research and development activities; establishment of an appropriate safety profile with IND-enabling studies; successful patient enrollment in, and the initiation and completion of, clinical trials; the timing, receipt and terms of any marketing approvals from applicable regulatory authorities; • • • • 84 Table of Contents • • • • • establishment of commercial manufacturing capabilities or making arrangements with third-party manufacturers; development and timely delivery of commercial-grade drug formulations that can be used in our clinical trials and for commercial launch; acquisition, maintenance, defense and enforcement of patent claims and other intellectual property rights; significant and changing government regulation; initiation of commercial sales of our product candidates, if and when approved, whether alone or in collaboration with others; and • maintenance of a continued acceptable safety profile of the product candidates following approval. General and Administrative Expenses General and administrative ("G&A") expenses consist primarily of personnel costs, including salaries, benefits and travel expenses for our executive, finance, business, corporate development and other administrative functions; and share-based compensation expense. General and administrative expenses also include facilities and other related expenses, including rent, depreciation, maintenance of facilities, insurance and supplies; and for public relations, audit, tax and legal services, including legal expenses to pursue patent protection of our intellectual property. We anticipate that our general and administrative expenses, including payroll and related expenses, will remain significant in the future as we continue to support our research and development activities and prepare for potential commercialization of our product candidates, if successfully developed and approved. We also anticipate increased expenses associated with general operations, including costs related to accounting and legal services, director and officer insurance premiums, facilities and other corporate infrastructure, office-related costs, such as information technology costs, and certain costs to establish ourself as a standalone public company, as well as ongoing additional costs associated with operating as an independent, publicly traded company. Other Income (Expense) Gain (Loss) from Equity Method Investment Prior to our acquisition of Kleo in January 2021, we owned approximately 41.9% of the outstanding shares as of December 31, 2020, and accounted for our investment in Kleo under the equity method of accounting. As a result, our proportionate share of Kleo’s net income or loss each reporting period was included in other income (expense), net, in our consolidated statement of operations and results in a corresponding adjustment to the carrying value of the equity method investment on our consolidated balance sheet. On January 4, 2021, we acquired the rest of the shares of Kleo, and post-transaction we own 100% of the outstanding shares of Kleo. Other (Expense) Income, Net Other (expense) income, net during the year ended December 31, 2022 primarily consisted of a $10.0 million impairment loss recognized during the fourth quarter on our Artizan Series A-2 Preferred Stock Investment, partially offset by net investment income of $3.2 million and service revenue from the Transition Service Agreement we entered into with the Former Parent of $4.0 million. Other (expense) income, net during the year ended December 31, 2021 primarily consisted of a gain recognized upon the Company’s determination that the value of the contingent value right related to our Kleo acquisition was immaterial as of December 31, 2021. The consideration transferred for the Kleo acquisition included contingent consideration in the form of a contingent value right to receive one dollar in cash for each Kleo share if certain specified Kleo biopharmaceutical products or product candidates receive the approval of the FDA prior to the expiration of 30 months following the effective time of the transaction. The maximum amount payable pursuant to the contingent value right was approximately $17.3 million. At December 31, 2021, the Company determined the value of the contingent value right to be immaterial and recognized a gain of $1.5 million related to the contingent value right in other income, net. Provision for Income Taxes The income tax expense in the consolidated financial statements has been calculated on a separate return method and is presented as if the Company’s operations were separate taxpayers in the respective jurisdictions up to and including the Separation. Cash tax payments, income taxes receivable and deferred taxes, net of valuation allowance, are reflective of our actual tax balances prior and subsequent to the Separation. As a company incorporated in the BVI, we are principally subject to taxation in the BVI. Under the current laws of the BVI, the Company and all dividends, interest, rents, royalties, compensation and other amounts paid by the Company to persons who are not resident in the BVI and any capital gains realized with respect to any shares, debt obligations, or other securities of the Company by persons who are not resident in the BVI are exempt from all provisions of the Income Tax Ordinance in the BVI. We have historically outsourced all of the research and clinical development for its programs under a master services agreement with Biohaven Pharmaceuticals, Inc. ("BPI"). As a result of providing 85 Table of Contents services under this agreement, BPI was profitable during the years ended December 31, 2022, 2021, and 2020, and BPI is subject to taxation in the United States. As such, in each reporting period, the tax provision includes the effects of combining the results of operations of BPI. At December 31, 2022 and 2021, we continued to maintain a full valuation allowance against our net deferred tax assets, comprised primarily of capitalized research and development deductions, research and development tax credit carryforwards, and net operating loss carryforwards, based on management’s assessment that it is more likely than not that the deferred tax assets will not be realized. We recorded an income tax expense for the year ended December 31, 2022 of $0.4 million and an expense of $1.4 million for the year ended December 31, 2021, which primarily represents U.S. Federal and state taxes related to BPI’s profitable operations in the United States. In January 2021, we completed the acquisition of Kleo. We recorded a full valuation allowance against our Kleo deferred tax assets and periodically review our position. Due to Kleo's cumulative loss history, we determined that a full valuation allowance on these assets was appropriate. We will continue to evaluate the need for a valuation allowance on our deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances. 86 Table of Contents Results of Operations Comparison of the Years Ended December 31, 2022 and 2021 The following table summarizes our results of operations for the years ended December 31, 2022 and 2021: In thousands Operating expenses: Research and development General and administrative Total operating expenses Loss from operations Other (expense) income : Gain from equity method investment Other (expense) income, net Total other (expense) income, net Loss before provision for income taxes Provision for income taxes Net loss Research and Development Expenses In thousands Direct research and development expenses by program: BHV-7000 Troriluzole Verdiperstat BHV-1100 BHV-1200 (COVID 19) BHV-2000 Other programs Unallocated research and development costs: Personnel related (including non-cash share-based compensation) Preclinical research programs Other Total research and development expenses Year Ended December 31, 2022 2021 Change 437,072 $ 130,860 567,932 (567,932) — (1,909) (1,909) (569,841) 438 (570,279) $ 181,486 $ 37,414 218,900 (218,900) 5,261 1,209 6,470 (212,430) 1,366 (213,796) $ 255,586 93,446 349,032 (349,032) (5,261) (3,118) (8,379) (357,411) (928) (356,483) $ $ Year Ended December 31, 2021 2022 Change $ $ 131,006 $ 58,769 13,654 852 6,033 16,799 731 170,122 25,865 13,241 437,072 $ — $ 50,637 30,664 1,476 3,023 820 288 64,308 22,592 7,678 181,486 $ 131,006 8,132 (17,010) (624) 3,010 15,979 443 105,814 3,273 5,563 255,586 R&D expenses, including non-cash share-based compensation costs, were $437.1 million for the year ended December 31, 2022, compared to $181.5 million for the year ended December 31, 2021. The increase of $255.6 million was primarily due to an increase of $131.0 million in expense for BHV-7000, an increase of $16.0 million in expense for BHV-2000, and an increase of $105.8 million in personnel costs. The $131.0 million increase in expense for BHV-7000 was primarily due to the Kv7 Platform Acquisition which resulted in $93.7 million of expense recorded to R&D, and a $25.0 million milestone expense, both recognized during the second quarter of 2022. The increase of $105.8 million in personnel costs was primarily due to increases in non-cash share-based compensation expense of $77.0 million, increased headcount to support acquired and late-stage programs, and $5.2 million of one-time employee costs related to the Pfizer acquisition of the Former Parent in the fourth quarter of 2022. These increases were partially offset by a decrease in program expense for verdiperstat of $17.0 million. Non-cash share-based compensation expense was $116.4 million for the year ended December 31, 2022, an increase of $77.0 million as compared to the same period in 2021. Non-cash share- based compensation expense for the year ended December 31, 2022 included $108.7 million amount of expense allocated from the Former Parent, including $61.7 million of expense recognized in connection with the settlement of 87 Table of Contents outstanding Former Parent stock options and RSUs upon the effectiveness of the Separation. General and Administrative Expenses G&A expenses, including non-cash share-based compensation costs, were $130.9 million for the year ended December 31, 2022, compared to $37.4 million for the year ended December 31, 2021. The increase of $93.4 million was primarily due to increases of $50.9 million in non-cash share-based compensation expense, and $14.1 million of transaction expenses and $8.9 million of one-time personnel expenses related to the Pfizer acquisition of the Former Parent and spin-off of Biohaven Ltd. as an independent, publicly traded company in 2022. Non-cash share-based compensation expense was $77.2 million for the year ended December 31, 2022, an increase of $50.9 million as compared to the same period in 2021. Non-cash share-based compensation expense for the year ended December 31, 2022 included $70.6 million amount of expense allocated from the Former Parent, including $39.7 million of expense recognized in connection with the settlement of each outstanding Former Parent stock option and RSU upon the effectiveness of the Separation. Other Income (Expense), Net Other income (expense), net was a net expense of $1.9 million for the year ended December 31, 2022, compared to other income of $6.5 million for the year ended December 31, 2021. The change of $8.4 million was primarily due to a $10.0 million impairment loss recognized during the fourth quarter on our Artizan Series A-2 Preferred Stock Investment and the acquisition of Kleo in January 2021, which resulted in a gain of $5.3 million being recognized during 2021 upon our remeasurement to fair value of the existing equity interest in Kleo, partially offset by net investment income of $3.2 million and service revenue from the Transition Service Agreement we entered into with the Former Parent of $4.0 million. Provision for Income Taxes We recorded a provision for income taxes of $0.4 million for the year ended December 31, 2022, compared to a provision for income taxes of $1.4 million for the year ended December 31, 2021. The decrease in income tax expense was primarily attributable to the vesting of share based compensation awards to employees and the Foreign-Derived Intangible Income ("FDII") deduction, offset by the mandatory capitalization of R&D expenses effective January 1, 2022 under the Tax Cuts and Jobs Act. 88 Table of Contents Comparison of the Years Ended December 31, 2021 and 2020 The following table summarizes our results of operations for the years ended December 31, 2021 and 2020: In thousands Operating expenses: Research and development General and administrative Total operating expenses Loss from operations Other (expense) income : Gain (loss) from equity method investment Other income, net Total other income (expense), net Loss before provision for income taxes Provision for income taxes Net loss Research and Development Expenses In thousands Direct research and development expenses by program: Troriluzole Verdiperstat BHV-1100 BHV-1200 (COVID 19) Other programs Unallocated research and development costs: Personnel related (including non-cash share-based compensation) Preclinical research programs Other Total research and development expenses Research and development expenses were $181.5 million for the year ended December 31, 2021, compared to $98.5 million for the year ended December 31, 2020. The increase of $83.0 million was primarily due to increases of $8.5 million in direct costs for the troriluzole program, $9.6 million in direct costs for the verdiperstat program, $33.2 million in personnel related costs, and $21.2 million in costs related to our preclinical research programs. The increase in personnel costs of $33.2 million was primarily a result of hiring additional personnel to support the expanding number of clinical trials and preclinical programs. Personnel-related costs for the years ended December 31, 2021 and 2020 included non-cash share-based compensation expense of $39.4 million and $18.5 million, respectively. The $21.2 million increase in preclinical research costs was primarily due to the following: an upfront Year Ended December 31, 2020 2021 Change $ $ 181,486 $ 37,414 218,900 (218,900) 5,261 1,209 6,470 (212,430) 1,366 (213,796) $ 98,460 $ 16,046 114,506 (114,506) (4,162) — (4,162) (118,668) — (118,668) $ 83,026 21,368 104,394 (104,394) 9,423 1,209 10,632 (93,762) 1,366 (95,128) Year Ended December 31, 2020 2021 Change $ $ 50,637 $ 30,664 1,476 3,023 288 64,308 22,592 7,678 180,666 $ 42,101 $ 21,036 — — 390 31,060 1,434 2,439 98,460 $ 8,536 9,628 1,476 3,023 (102) 33,248 21,158 5,239 82,206 payment of $2.0 million to Yale University in connection with the Yale MoDE Agreement; an upfront payment of $5.9 million to Moda Pharmaceuticals LLC in connection with a consulting agreement to further the scientific advancement of technology, drug discovery platforms (including the technology licensed under the Yale MoDE Agreement), product candidates and related intellectual property owned or controlled by the Company; and a $3.8 million upfront payment to Reliant Glycosciences, LLC in connection with a development and license agreement to develop and commercialize conjugated antibodies for therapeutic uses relating to IgA nephropathy and treatment of other diseases and conditions. The remainder of the increase primarily related to the rise in the number of ongoing preclinical research programs, including increased costs for outsourced chemistry and research arrangements. 89 Table of Contents General and Administrative Expenses General and administrative expenses were $37.4 million for the year ended December 31, 2021, compared to $16.0 million for the year ended December 31, 2020 The increase of $21.4 million was primarily due to increased personnel-related expenses of $16.4 million, including non-cash share-based compensation expense, and a $2.0 million increase in expenses related to accounting, legal and other professional fees. Non-cash share-based compensation expense included in personnel-related costs increased $15.2 million, from $11.0 million for the year ended December 31, 2020 to $26.3 million for the year ended December 31, 2021, primarily due to annual equity incentive awards that were granted by the Formers Parent in the first quarter of 2021. Other Income (Expense), Net Other income (expense), net was a net other income of $6.5 million for the year ended December 31, 2021, compared to net other expense of $4.2 million for the year ended December 31, 2020. The change of $10.6 million in net other income (expense) was primarily due to a $9.4 million change in gain (loss) on equity investment, primarily due to the acquisition of Kleo Pharmaceuticals, Inc. in January 2021, which resulted in a gain of $5.3 million being recognized during 2021 upon our remeasurement to fair value of the existing equity interest in Kleo. The decrease was also due to a $1.2 million increase in other income, net, which was primarily due to a $1.5 million gain recognized in 2021 upon the Company’s determination that the fair value of a contingent value right recorded relating to the acquisition of Kleo Pharmaceuticals was immaterial as of December 31, 2021. Provision for Income Taxes We recorded a provision for income taxes of $1.4 million for December 31, 2021 and $0.0 million for the year ended December 31, 2020. The increase in tax expense for the year ended December 31, 2021 is primarily related to the decrease in the tax deductions arising from stock based compensation awards to employees. Liquidity and Capital Resources Since our inception as a business of the Former Parent, we have not generated any revenue and have incurred significant operating losses and negative cash flows from operations. We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for our product candidates. We expect to continue to incur significant expenses for at least the next several years as we advance our product candidates from discovery through preclinical development and clinical trials and seek regulatory approval and pursue commercialization of any approved product candidate. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. In addition, we may incur expenses in connection with the in-license or acquisition of additional product candidates. Historically, for periods prior to our separation from the Former Parent, we have funded our operations primarily with proceeds allocated to our business from financing arrangements entered into by the Former Parent and through the one-time issuance of contingently redeemable non-controlling interests. Prior to the Separation, transfers of cash for general operating, investing, and financing activities and net cost allocation from the Former Parent were reflected in net investment from Former Parent in our consolidated balance sheets. The cash reported on our consolidated balance sheet for periods prior to the Separation represents cash held by Biohaven entities at the end of the period presented. Pursuant to the Distribution Agreement, immediately prior to the Separation, the Former Parent made a cash contribution to the Company which resulted in a cash balance of approximately $257.8 million as of October 3, 2022. Additionally, on October 25, 2022, we completed a public offering of 28,750,000 of our common shares, including the full exercise of the underwriters' option to purchase additional shares, at a public offering price of $10.50 per share. The offering resulted in net proceeds, after deducting underwriting discounts and expenses of the offering payable by Biohaven, of approximately $282.8 million. As of December 31, 2022, we had cash and cash equivalents of $204.9 million, excluding marketable securities of $260.5 million and restricted cash of $37.7 million of which $35.2 million related to restricted cash held on behalf of Former Parent and $2.5 million related to collateral held by banks for letters of credit (“LOC”) issued in connection with leased office space in Yardley, Pennsylvania and Cambridge, Massachusetts. Cash in excess of immediate requirements is invested in marketable securities and money market funds with a view to liquidity and capital preservation. We continuously assess our working capital needs, capital expenditure requirements, and future investments or acquisitions. 90 Table of Contents Cash Flows The following table summarizes our cash flows for each of the periods presented: In thousands Net cash used in operating activities Net cash (used in) provided by investing activities Net cash provided by financing activities Effect of exchange rate changes on cash and cash equivalents and restricted cash Net increase (decrease) in cash, cash equivalents and restricted cash Year Ended December 31, 2022 2021 2020 (297,689) $ (304,790) 767,597 429 165,547 $ (145,840) $ 944 138,447 — (6,449) $ (75,957) (2,697) 152,242 — 73,588 $ $ Operating Activities Net cash used in operating activities was $297.7 million in 2022, $145.8 million in 2021, and $76.0 million in 2020. The $151.9 million increase in net cash used in operating activities in 2022 was driven primarily by: • • • an increase in net loss primarily due to an increase in R&D spending including a $25.0 million milestone payment to Knopp Biosciences, LLC (see Note 6 to the Consolidated Financial Statements), an increase in R&D headcount to support acquired and late-stage programs, and an increase in payments related to accounting, legal and other professional fees associated with the Pfizer acquisition of the Former Parent and spin-off of Biohaven Ltd; an increase in prepaid R&D expenses to support our clinical trials; and increased cash payments for income taxes. The $69.8 million increase in net cash used in operating activities in 2021 was unfavorably impacted by an increase in net loss primarily due to: • • an increase in R&D spending including upfront payments of $3.7 million for various license agreements (see Note 11 to the Consolidated Financial Statements); and an increase in headcount to support the Company's growing operations. Investing Activities Net cash used in investing activities was $304.8 million in 2022 and $2.7 million in 2020, and net cash provided by investing activities was $0.9 million in 2021. The $305.7 million increase in net cash used in investing activities in 2022 was driven primarily by: • • payment for our acquisition of Channel Biosciences, LLC (see Note 6 to the Consolidated Financial Statements); and purchase of series A-2 preferred stock of Artizan Biosciences Inc (see Note 11 to the Consolidated Financial Statements). The $3.6 million increase in net cash provided by investing activities in 2021 was driven primarily by cash acquired from the business acquisition of Kleo Pharmaceuticals, Inc (see Note 6 to the Consolidated Financial Statements). Financing Activities Net cash provided by financing activities was $767.6 million in 2022, $138.4 million in 2021, and $152.2 million in 2020. The $629.2 million increase in net cash provided by financing activities in 2022 was driven primarily by: • • • an increase in proceeds from net transfers from Parent prior to and at the Separation for our general operating, investing, and financing activities and net cost allocations and initial capitalization; restricted cash held in connection with the execution of the United States Distribution Services Agreement which is legally payable to the Former Parent (see Note 14 to the Consolidated Financial Statements); and proceeds from the issuance of common shares related to a public offering in October 2022 (see Note 7 to the Consolidated Financial Statements). The $13.8 million decrease in net cash provided by financing activities in 2021 was driven primarily by a decrease in proceeds from net transfers from Former Parent for our general operating, investing, and financing activities and net cost allocations. Funding Requirements • • purchases of marketable securities with cash in excess of immediate requirements (see Note 3 to the Consolidated Financial Statements); We expect our expenses to increase in connection with our ongoing activities, particularly as we advance and expand preclinical activities, clinical trials and an increase in purchases of equipment to support our discovery programs; 91 Table of Contents potential commercialization of our product candidates. Our costs will also increase as we: depending on where we choose to commercialize or whether we commercialize jointly or on our own. • • • • • • • • • continue to advance and expand the development of our clinical-stage assets; continue to initiate and progress other supporting studies required for regulatory approval of our product candidates, including long-term safety studies, drug-drug interaction studies, preclinical toxicology and carcinogenicity studies; initiate preclinical studies and clinical trials for any additional indications for our current product candidates and any future product candidates that we may pursue; continue to build our portfolio of product candidates through the acquisition or in-license of additional product candidates or technologies; continue to develop, maintain, expand and protect our intellectual property portfolio; pursue regulatory approvals for our current and future product candidates that successfully complete clinical trials; support our sales, marketing and distribution infrastructure to commercialize any future product candidates for which we may obtain marketing approval; hire additional clinical, medical, commercial, and development personnel; and incur additional legal, accounting and other expenses in operating as a public company. We expect that our cash, cash equivalents and marketable securities, as of the date of this Annual Report on Form 10-K, will be sufficient to fund our current forecast for operating expenses, financial commitments and other cash requirements for more than one year. We expect we will need to raise additional capital until we are profitable. If no additional capital is raised through either public or private equity financings, debt financings, strategic relationships, alliances and licensing agreements, or a combination thereof, we may delay, limit or reduce discretionary spending in areas related to research and development activities and other general and administrative expenses in order to fund our operating costs and working capital needs. We have based these estimates on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we expect. We expect that we will require additional capital to pursue in-licenses or acquisitions of other product candidates. If we receive regulatory approval for troriluzole, or our other product candidates, we expect to incur commercialization expenses related to product manufacturing, sales, marketing and distribution, Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on and could increase significantly as a result of many factors, including: • • • • • • the scope, progress, results and costs of researching and developing our product candidates, and conducting preclinical studies and clinical trials; the costs, timing and outcome of regulatory review of our product candidates; the effect of COVID-19 pandemic on our business operations and funding needs; the costs and timing of hiring new employees to support our continued growth; the costs of preparing, filing, and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims; and the extent to which we acquire or in-license other product candidates and technologies Until such time, if ever, that we can generate product revenue sufficient to achieve profitability, we expect to finance our cash needs through a combination of public and private equity offerings, debt financings, other third-party funding, strategic alliances, licensing arrangements or marketing and distribution arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing shareholders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through other third-party funding, strategic alliances, licensing arrangements or marketing and distribution arrangements, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we will be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market products or product candidates that we would otherwise prefer to develop and market ourselves. 92 Table of Contents Contractual Obligations and Commitments The following table summarizes certain estimated future obligations by period under our various contractual obligations as of December 31, 2022 and the effects that such obligations are expected to have on our liquidity and cash flows in future periods: In thousands Operating leases Purchase obligations (1) Research commitments (2) Total Total 2023 Payments Due by Period 2024-2025 2026-2027 Thereafter $ $ 44,579 $ 4,929 $ 9,723 $ 9,364 $ 20,563 16,457 61,036 $ 16,457 21,386 $ — 9,723 $ — 9,364 $ — 20,563 (1) Refer to Note 12, "Commitments and Contingencies" to the consolidated financial statements included in this 10-K for additional information on future minimum rental commitments under non-cancelable operating leases. (2) Research commitments are primarily CRO agreements that are enforceable and legally binding on us and that specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. For obligations with cancellation provisions, the amounts included in the preceding table are limited to the non-cancelable portion of the agreement terms or the minimum cancellation fee. In addition to the amounts above, as of December 31, 2022, the Company had remaining maximum research commitments in excess of one year of approximately $18,750, which are variable based on number of trial participants and contingent upon the achievement of certain milestones of the clinical trials covered under the agreements. Since the achievement of these milestones is uncertain and the timing unpredictable, the Company did not include the additional research commitments in the table above. If all related milestones are achieved, the Company expects these amounts to be paid over the next five years. In addition to the contractual obligations in the table above, under various agreements with third-party licensors and collaborators, we have agreed to make milestone payments and pay royalties and annual maintenance fees to third parties and to meet due diligence requirements based upon specified milestones. We have not included any contingent payment obligations, such as milestones, royalties, or due diligence, in the table above as the amount, timing and likelihood of such payments are not known. We have not included any of the annual license maintenance fee payments in the above table, as although the amount and timing are known, we cannot currently determine the final termination dates of the agreements and, as a result, we cannot determine the total amounts of such payments we will be required to make under the agreements. We do not anticipate making material annual license maintenance payments related to our license agreements in the next 12 months. Critical Accounting Policies and Significant Judgments and Valuation and Impairment of Intangible Assets Estimates Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States ("GAAP"). The preparation of our consolidated financial statements and related disclosures requires us to make estimates, assumptions, and judgments that affect the reported amounts of assets, liabilities, expenses, and related disclosures at the date of the consolidated financial statements. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in Note 2, "Summary of Significant Accounting Policies" in the notes to our financial statements appearing at the end of this Annual Report, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements. In-Process Research and Development (“IPR&D”) that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and accounted for as indefinite- lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, the Company will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The fair value of acquired intangible assets is primarily determined using an income-based approach referred to as the multi- period excess earnings method utilizing Level 3 fair value inputs. The market participant valuation assumes a global view considering all potential jurisdictions and indications based on discounted after-tax cash flow projections, risk adjusted for estimated probability of technical and regulatory success. 93 Table of Contents The Company evaluates IPR&D for impairment at least annually in the fourth quarter and more frequently if impairment indicators exist, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. Accrued Research and Development Expenses As part of the process of preparing the consolidated financial statements, we are required to estimate accrued research and development expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on its behalf and estimating the level of service performed and the associated cost incurred for the service when it has not yet been invoiced or otherwise notified of actual costs. The majority of our service providers invoice in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in the consolidated financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of these estimates with the service providers and make adjustments if necessary. Examples of estimated accrued research and development expenses include fees paid to: status and timing of services performed relative to the actual status and timing of services performed may vary and may result in reporting amounts that are too high or too low in any particular period. To date, there have not been any material adjustments to our prior estimates of accrued research and development expenses. Cost Allocations Prior to the distribution on October 3, 2022, we have historically operated as part of the Former Parent and not as separate, publicly traded company. Accordingly, for periods prior to the distribution, certain shared costs and non-cash share-based compensation expenses have been allocated to us and are reflected as expenses in the accompanying consolidated statement of operations. Management considers the expense methodology and resulting allocation to be reasonable for all periods presented; however, the allocations may not be indicative of actual expenses that would have been incurred had we operated as an independent, publicly traded company for the periods presented. Actual costs that we may have incurred had we been a stand-alone company would depend on a number of factors, including the organizational structure, what corporate functions the Company might have performed directly or outsourced and strategic decisions the Company might have made in areas such as executive management, legal and other professional services, and certain corporate overhead functions. • vendors, including central laboratories, in connection with Recently Issued Accounting Pronouncements preclinical development activities; • CROs and investigative sites in connection with preclinical and clinical studies; and • CMOs in connection with drug substance and drug product A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 2 to our consolidated financial statements appearing at the end of this Annual Report. formulation of preclinical and clinical trial materials. Emerging Growth Company Status We base expenses related to preclinical studies and clinical trials We are an “emerging growth company,” as defined in the on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple research institutions and CROs that conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the estimate, we adjust the accrual or the amount of prepaid expenses accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the Jumpstart Our Business Startups (JOBS) Act (the "JOBS Act"), and we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies.” These exemptions generally include, but are not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We plan to take advantage of some or all of the reduced regulatory and reporting requirements that will be available to us as long as we qualify as an emerging growth company, except that we have irrevocably elected not to take advantage of the extension of time to comply with new or revised financial accounting 94 Table of Contents standards available under Section 102(b) of the JOBS Act. We do not engage in any hedging activities against changes in We will, in general, remain as an emerging growth company for up to five full fiscal years following the Distribution. We would cease to be an emerging growth company and, therefore, become ineligible to rely on the above exemptions, if we: • • • have more than $1.235 billion in annual revenue in a fiscal year; issue more than $1 billion of non-convertible debt during the preceding three-year period; or become a “large accelerated filer” as defined in Exchange Act Rule 12b-2, which would occur after: (i) we have filed at least one annual report pursuant to the Exchange Act; (ii) we have been an SEC-reporting company for at least twelve months; and (iii) the market value of our common shares that is held by non-affiliates exceeds $700 million as of the last business day of our most recently completed second fiscal quarter. Smaller Reporting Company Status Additionally, we are a “smaller reporting company,” as defined in Rule 12b-2 under the Exchange Act. As such, we are eligible for exemptions from various reporting requirements applicable to other public companies that are not smaller reporting companies, including, but not limited to, reduced disclosure obligations regarding executive compensation. We will remain a smaller reporting company as long as either: (i) the market value of our common shares held by non-affiliates is less than $250 million as of the last business day of our most recently completed second fiscal quarter; or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our common shares held by non-affiliates is less than $700 million as of the last business day of our most recently completed second fiscal quarter. Item 7A. Quantitative and Qualitative Disclosures about Market Risks Foreign Currency Translation Our operations include activities in countries outside the U.S. As a result, our financial results are impacted by factors such as changes in foreign currency exchange rates or weak economic conditions in the foreign markets where we operate. Our monetary exposures on our consolidated balance sheets were immaterial to our financial position as of December 31, 2022 and 2021. foreign currency exchange rates. Interest Rate Risk As of December 31, 2022, we invest our excess cash balances in marketable securities of highly rated financial institutions and investment-grade debt instruments. We seek to diversify our investments and limit the amount of investment concentrations for individual institutions, maturities and investment types. Most of our interest-bearing securities are subject to interest rate risk and could decline in value if interest rates fluctuate. Based on the type of securities we hold, we do not believe a change in interest rates would have a material impact on our financial statements. If interest rates were to increase or decrease by 1.00%, the fair value of our investment portfolio would (decrease) increase by approximately $(1.4) million and $1.4 million, respectively. The Company did not have any investments in marketable securities as of December 31, 2021. For further discussion of our investments in marketable securities, refer to Note 3, "Marketable Securities," of the Notes to the Consolidated Financial Statements appearing elsewhere in this Annual Report on Form 10-K. We do not engage in any hedging activities against changes in interest rates. Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist of cash, cash equivalents, and short-term debt securities. The Company maintains a portion of its cash deposits in government insured institutions in excess of government insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts. The Company's cash management policy permits investments in U.S. federal government and federal agency securities, corporate bonds or commercial paper, supranational and sovereign obligations, certain qualifying money market mutual funds, certain repurchase agreements, and places restrictions on credit ratings, maturities, and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash in excess of government insured limits and in the event of default by corporations and governments in which it holds investments in cash equivalents and short-term debt securities, to the extent recorded on the consolidated balance sheet.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Evaluation of Disclosure Controls and Procedures The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), refers to controls and procedures that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to a company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a control system, misstatements due to error or fraud may occur and not be detected. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2022, our disclosure controls and procedures were effective at the reasonable assurance level. Management's Report on Internal Control over Financial Reporting This Annual Report does not include a report of management’s assessment regarding internal control over financial reporting or an attestation report of our independent registered public accounting firm as allowed by the SEC during the transition period for newly public companies. 96 Table of Contents Changes in Internal Controls over Financial Reporting There have been no changes in our internal control over financial Biohaven is now solely responsible, and has agreed to use reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. ITEM 9B. OTHER INFORMATION On March 21, 2023, Biohaven, through its wholly owned subsidiary Biohaven Therapeutics Ltd., entered into a License Agreement (the “Highlight II Agreement”) with Hangzhou Highlightll Pharmaceutical Co. Ltd. (“Highlightll”). Pursuant to the Highlightll Agreement, Highlightll granted Biohaven exclusive worldwide rights, excluding the People’s Republic of China and its territories and possessions, to research, develop, manufacture and commercialize Highlightll’s brain penetrant dual TYK2/JAK1 tyrosine kinase (“TYK2/JAK1”) inhibitor program. Biohaven plans to conduct a Phase 1 study of this product candidate, which will now be referred to as BHV- 8000, for the treatment of brain disorders. As partial consideration for the Highlightll Agreement, the Company is obligated to pay Highlightll a cash payment of $10 million and common shares valued at approximately $10 million as of the agreement execution, upon the completion of certain post-closing activities. Under the terms of the Highlightll Agreement, Biohaven will also be obligated to make milestone payments to Highlightll totaling up to $200 million upon the achievement of specified developmental, regulatory and commercial milestones for a first indication, up to $100 million upon the achievement of specified developmental, regulatory and commercial milestones for a second indication, and up to $650 million upon the achievement of specified sales-based milestones. No additional milestone payments will be due for any indications beyond the first and second indications. In addition, Biohaven will pay Highlightll tiered royalties ranging from mid single-digit to low teens based on net sales of any approved products based on BHV-8000, subject to specified reductions. Under the terms of the Highlightll Agreement, Biohaven may pursue development and commercialization of BHV-8000 for all indications, except, for a period of five years from the date of the first commercial sale of the first licensed product, the prevention, treatment or diagnosis of any disorders that cause inflammation in the bones, muscles, joints, respiratory system, gastro-intestinal system and skin. Highlightll has agreed not to develop or commercialize, for a period of five years from the date of the first commercial sale of the first licensed product, any TYK2/JAK1inhibitor program for the prevention, treatment or diagnosis of any neurological disorder. commercially reasonable efforts, for all development, regulatory and commercial activities related to BHV-8000. Biohaven may sublicense its rights under the Highlightll Agreement, subject to Highlightll’s prior written consent. Biohaven is also now responsible for the prosecution and maintenance of the patents related to BHV-8000 and licensed products, and has the first right to prosecute infringement of the patents and defend challenges to the validity or enforceability of the patents in all countries other than the People’s Republic of China and its territories and possessions. The Highlightll Agreement terminates on a country-by-country basis and product-by-product basis upon the expiration of the royalty term for a product in a country.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Biohaven Ltd. (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ Ernst & Young LLP We have served as the Company’s auditor since 2022.

Nature of the Business and Basis of Presentation Biohaven Ltd. (“we,” “us," "our," "Biohaven" or the “Company”) was incorporated in Tortola, British Virgin Islands in May 2022. Biohaven is a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies for people with debilitating neurological and neuropsychiatric diseases, including rare disorders. Biohaven's experienced management team brings with it a track record of delivering new drug approvals for products for diseases such as migraine, depression, bipolar and schizophrenia. The company is advancing a pipeline of therapies for diseases with little or no treatment options, leveraging its proven drug development capabilities and proprietary platforms, including Kv7 ion channel modulation for epilepsy and neuronal hyperexcitability, glutamate modulation for Obsessive-Compulsive Disorder ("OCD") and spinocerebellar ataxia ("SCA"), myostatin inhibition for neuromuscular diseases, and brain-penetrant Tyrosine Kinase 2/Janus Kinase 1 ("TYK2/JAK1") inhibition for immune- mediated brain disorders. Biohaven's portfolio of early- and late-stage product candidates also includes discovery research programs focused on TRPM3 channel activation for neuropathic pain, CD-38 antibody recruiting, bispecific molecules for multiple myeloma, antibody drug conjugates ("ADCs"), and extracellular target degrader platform technology ("MoDE") with potential application in neurological disorders, cancer, and autoimmune diseases. (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), which provided for the acquisition by Pfizer of the Former Parent through the merger of Merger Sub with and into the Former Parent (the “Merger”). In connection with the Merger Agreement, the Former Parent and Biohaven Ltd. entered into a Separation and Distribution Agreement, dated as of May 9, 2022 (the “Distribution Agreement”). In connection with the Distribution Agreement, the Board of Directors of the Former Parent approved and directed the Former Parent’s management to effect the Spin-Off of the business, operations, and activities that are not the CGRP Business (as defined below), including the Kv7 ion channel activators, glutamate modulation, MPO inhibition and myostatin inhibition platforms, preclinical product candidates, and certain corporate infrastructure currently owned by the Former Parent. To implement the Spin-Off, the Former Parent transferred the related license agreements, intellectual property and corporate infrastructure, including certain non-commercial employee agreements, share-based awards and other corporate agreements (the "Business") to Biohaven Ltd., through a series of internal restructuring transactions. Descriptions of historical business activities in these Notes to Consolidated Financial Statements are presented as if these transfers had already occurred, and the Former Parent’s activities related to such assets and liabilities had been performed by the Company. The Company is subject to risks and uncertainties common to On October 3, 2022, the Former Parent completed the distribution early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts may require additional capital, additional personnel and infrastructure, and further regulatory and other capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. Separation from Biohaven Pharmaceutical Holding Company Ltd. On May 9, 2022, Biohaven Pharmaceutical Holding Company Ltd. (the "Former Parent"), Pfizer Inc. (“Pfizer”) and a wholly owned subsidiary of Pfizer (the “Distribution”) to holders of its common shares of all of the outstanding common shares of Biohaven Ltd. and the spin-off of Biohaven from the Former Parent (the “Spin-Off”) described in Biohaven’s Information Statement (the “Information Statement”) attached as Exhibit 99.1 to Biohaven’s Registration Statement on Form 10, as amended (Reg. No. 001-41477), which was declared effective by the Securities and Exchange Commission ("SEC") on September 22, 2022 (the “Form 10”). Each holder of Former Parent common shares received one common share of Biohaven for every two Former Parent common shares held of record as of the close of business on September 26, 2022. In the Distribution, an aggregate of 35,840,459 Biohaven common shares were issued. The aggregate number of common shares issued in connection with the Distribution did not include 2,611,392 common shares to be issued in connection with Former Parent stock options that were exercised on October 3, 2022 and 924,093 common shares to be issued in connection with Former Parent restricted stock units that vested on October 3, 2022. See Note 9, "Non-Cash Share-Based Compensation" for discussion F-8 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 1. Nature of the Business and Basis of Presentation (Continued) of the Legacy Equity Award Settlement Plan. As a result of the Distribution, Biohaven Ltd. became an independent, publicly traded company. Collectively, we refer to the Distribution and Spin-Off throughout this Annual Report on Form 10-K as the "Separation." The Spin-Off generally resulted in (a) the Company directly or indirectly owning, assuming, or retaining certain assets and liabilities of the Former Parent and its subsidiaries related to the Former Parent’s pipeline assets and businesses and (b) the Former Parent directly or indirectly owning, assuming, or retaining all other assets and liabilities, including those associated with the Former Parent’s platform for the research, development, manufacture and commercialization of calcitonin gene-related receptor antagonists, including rimegepant, zavegepant and the Heptares Therapeutics Limited preclinical CGRP portfolio and related assets (the “CGRP Business”). In connection with the Separation, the Company entered into various agreements relating to transition services, licenses and certain other matters with the Former Parent. For additional information regarding these agreements, see Note 14, "Related Party Transactions." Basis of Presentation On October 3, 2022, the Company became a standalone publicly traded company, and its financial statements are now presented on a consolidated basis. Prior to the Separation on October 3, 2022, the Company’s historical combined financial statements were prepared on a standalone basis and were derived from the Former Parent's consolidated financial statements and accounting records. The financial statements for all periods presented, including the historical results of the Company prior to October 3, 2022, are now referred to as "Consolidated Financial Statements", and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Periods Prior to the Separation For periods prior to the Separation from the Former Parent, the consolidated financial statements present, on a historical basis, the combined assets, liabilities, expenses and cash flows directly attributable to the Business, which have been prepared from the Former Parent’s consolidated financial statements and accounting records, and are presented on a stand-alone basis as if the operations had been conducted independently from the Former Parent. The consolidated statements of operations for periods prior to the Separation include all costs directly related to the Business, including costs for facilities, functions and services utilized by the Company. The consolidated statements of operations periods prior to the Separation also include allocations for various expenses related to the Former Parent’s corporate functions, including research and development, human resources, information technology, facilities, tax, shared services, accounting, finance and legal. These expenses were allocated on the basis of direct usage or benefit when specifically identifiable, with the remainder allocated on a proportional cost allocation method primarily based on employee labor hours or direct expenses. Management believes the assumptions underlying the consolidated financial statements periods prior to the Separation, including the expense methodology and resulting allocation, are reasonable for all periods presented. However, the allocations may not include all of the actual expenses that would have been incurred by the Company and may not reflect its consolidated results of operations, financial position and cash flows had it been a standalone company during the periods presented. It is not practicable to estimate actual costs that would have been incurred had the Company been a standalone company and operated as an unaffiliated entity during the periods presented. Actual costs that might have been incurred had the Company been a standalone company would depend on a number of factors, including the chosen organizational structure, what corporate functions the Company might have performed directly or outsourced and strategic decisions the Company might have made in areas such as executive management, legal and other professional services, and certain corporate overhead functions. The income tax expense in the consolidated financial statements has been calculated on a separate return method and is presented as if the Company’s operations were separate taxpayers in the respective jurisdictions up to and including the Distribution. Cash tax payments, income taxes receivable and deferred taxes, net of valuation allowance, are reflective of its actual tax balances prior and subsequent to the Distribution. The consolidated balance sheets for periods prior to the Separation include assets and liabilities that have been determined to be specifically identifiable or otherwise attributable to the Company, including certain assets that were historically held at the corporate level in the Former Parent. All intracompany transactions within the Company have been eliminated. All intercompany transactions between the Company and the Former Parent are considered to be effectively settled in the consolidated financial statements at the time the transactions are recorded. The total net effect of these intercompany transactions considered to be F-9 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 1. Nature of the Business and Basis of Presentation (Continued) settled is reflected in the consolidated statement of cash flows within financing activities and in the consolidated balance sheets as “Net investment from Former Parent.” See Note 14, "Related Party Transactions", for additional information regarding related party transactions. For periods prior to the Separation, our equity balance in these consolidated financial statements represents the excess of total assets over liabilities. Net investment from Former Parent was primarily impacted by contributions from the Former Parent, which are the result of net funding provided by or distributed to Former Parent. As a result of the Separation, the Company’s Net investment from Former Parent balance was reclassified to common shares. The Net investment from Former Parent balance reclassified to common shares included separation-related adjustments of $27,811. The adjustments related primarily to differences in the amount of assets and liabilities transferred to the Company upon the Separation and the amount of the transferred assets and liabilities reported in the company’s combined balance sheet as of September 30, 2022. Additional separation-related adjustments could be recorded in future periods. Cash on the consolidated balance sheet for periods prior to the Separation represents cash balances from the standalone entities established to operate the Business. of approximately $282,804. See Note 7, "Shareholders' Equity", for further detail on the public offering. Accordingly, as of the date of issuance of these consolidated financial statements, the Company expects its existing cash, cash equivalents and marketable securities will be sufficient to fund operating expenses, financial commitments and other cash requirements for at least one year after the issuance date of these financial statements. To execute its business plans, the Company will require funding to support its continuing operations and pursue its growth strategy. Until such time as the Company can generate significant revenue from product sales or royalties, if ever, it expects to finance its operations through the sale of public or private equity, debt financings or other capital sources, including collaborations with other companies or other strategic transactions. The Company may not be able to obtain financing on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s shareholders. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate some or all of its research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects, or the Company may be unable to continue operations. 2. Summary of Significant Accounting Policies Going Concern Use of Estimates In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. Through March 23, 2023, the Company has funded its operations primarily with proceeds from its Former Parent, its recent public offering as discussed in Note 7, "Shareholders' Equity", and the cash contribution received from the Former Parent at the Separation as discussed below. The Company has incurred recurring losses since its inception and expects to continue to generate operating losses for the foreseeable future. Pursuant to the Distribution Agreement, immediately prior to the Separation, the Former Parent made a cash contribution to the Company which resulted in a cash balance of approximately $257,799 as of October 3, 2022. Additionally, on October 25, 2022, the Company completed a public offering of its common shares which resulted in net proceeds to the Company The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting periods. Significant estimates and assumptions reflected in these consolidated financial statements include, but are not limited to, the valuation of intangible assets, determining the allocations of costs and expenses from the Former Parent and the accrual for research and development expenses. In addition, management’s assessment of the Company’s ability to continue as a going concern involves the estimation of the amount and timing of future cash inflows and outflows. Estimates are periodically reviewed in light of changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates. F-10 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 2. Summary of Significant Accounting Policies (Continued) Reclassifications Certain items in the prior period’s consolidated financial statements have been reclassified to conform to the current year presentation. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of 90 days or less at the date of purchase to be cash equivalents. The Company's cash equivalents are comprised of short- term money market funds and marketable securities that are highly liquid and readily convertible to known amounts of cash. Restricted Cash Restricted cash held on behalf of the Former Parent on the consolidated balance sheet as of December 31, 2022 represents cash held by the Company on behalf of the Former Parent related to the execution of the United States Distribution Services Agreement (the “Distribution Services Agreement”). Pursuant to the terms of the Distribution Services Agreement, which was entered into by the Company and the Former Parent in connection with the Separation, the Company is continuing to serve as the Former Parent’s distributor and agent for the distribution of the pharmaceutical product Nurtec ODT in the United States. As of December 31, 2022, the Company recorded a related payable of $35,212 as Due to Former Parent on the consolidated balance sheet as the balance was legally payable to the Former Parent. Refer to Note 14, "Related Party Transactions" for further information on the agreements entered into by the Company and the Former Parent in connection with the Separation. Restricted cash included in other current assets includes employee contributions to the Company's employee share purchase plan held for future purchases of the Company's outstanding shares. See Note 9, "Non-Cash Share-Based Compensation" for additional information on the Company's employee share purchase plan. The Company did not have an employee share purchase plan as of December 31, 2021. Restricted cash included in other assets in the consolidated balance sheets represents collateral held by banks for a letter of credit ("LOC") issued in connection with the leased office space in Yardley, Pennsylvania and a LOC issued in connection with the leased office space in Cambridge, Massachusetts. See Note 12, ‘‘Commitments and Contingencies’’ for additional information on the real estate leases. The following represents a reconciliation of cash and cash equivalents in the consolidated balance sheets to total cash, cash equivalents and restricted cash for the years ended December 31, 2022, 2021 and 2020, respectively, in the consolidated statements of cash flows: December 31, 2021 2020 2022 204,877 $ $ 76,057 $ 82,506 — 250 750 — — 1,000 35,212 117 2,398 $ 242,604 $ 77,057 $ 83,506 Cash and cash equivalents Restricted cash held on behalf of Former Parent Restricted cash (included in other current assets) Restricted cash (included in other non-current assets) Total cash, cash equivalents and restricted cash at the end of the period in the consolidated statement of cash flows Marketable Securities We invest our excess cash balances in marketable securities of highly rated financial institutions and investment-grade debt instruments. We seek to diversify our investments and limit the amount of investment concentrations for individual institutions, maturities and investment types. We classify marketable debt securities as available- for-sale and, accordingly, record such securities at fair value. We classify these securities as current assets as these investments are intended to be available to the Company for use in funding current operations. Unrealized gains and losses on our marketable debt securities that are deemed temporary are included in accumulated other comprehensive income as a separate component of stockholders’ equity. If any adjustment to fair value reflects a significant decline in the value of the security, we evaluate the extent to which the decline is determined to be other-than-temporary and would mark the security to market through a charge to our consolidated statement of operations. Credit losses are identified when we do not expect to receive cash flows sufficient to recover the amortized cost basis of a security. In the event of a credit loss, only the amount associated with the credit loss is recognized in operating results, with the amount of loss relating to other factors recorded in accumulated other comprehensive income. Acquisitions Our consolidated financial statements include the operations of acquired businesses after the completion of the acquisitions. We account for acquired businesses F-11 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 2. Summary of Significant Accounting Policies (Continued) using the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date and that the fair value of acquired In-Process Research and Development ("IPR&D") be recorded on the balance sheet. Transaction costs are expensed as incurred. Any excess of the consideration transferred over the assigned values of the net assets acquired is recorded as goodwill. Contingent consideration in a business acquisition is included as part of the consideration transferred and is recognized at fair value as of the acquisition date. Fair value of IPR&D and contingent consideration is generally estimated by using a probability-weighted discounted cash flow approach. Equity Method Investments Investments in non-public companies in which the Company owns less than a 50% equity interest and where it has the ability to exercise significant influence over the operating and financial policies of the investee are accounted for using the equity method of accounting. The Company's proportionate share of the net income or loss of the equity method investment is included in other income (expense), net in the consolidated statement of operations and results in a corresponding adjustment to the carrying value of the investment on the consolidated balance sheet. Dividends received reduce the carrying value of the investment. As of December 31, 2020, the Company owned approximately 42% of the outstanding shares of Kleo Pharmaceuticals, Inc. ("Kleo"), which was accounted for as an equity method investment. In January 2021, the Company acquired the remaining 58% of Kleo's common shares that it did not previously own and ceased accounting for Kleo as an equity method investment. See Note 6, "Acquisitions" for additional details. Property and Equipment Property and equipment are recorded at cost and depreciated or amortized using the straight-line method over the estimated useful lives of the respective assets. As of December 31, 2022 and December 31, 2021, the Company's property and equipment consisted of office buildings and land, office and lab equipment, computer hardware and software, and furniture and fixtures. The fixed assets have the following useful lives: Building Office equipment Computer hardware and software Lab equipment Furniture and fixtures 30 years 3 - 5 years 3 - 5 years 3 years 3 years Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in loss from operations. Expenditures for repairs and maintenance are charged to expense as incurred. Property and equipment are monitored regularly for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Intangible Assets Acquired In-Process Research and Development IPR&D that the Company acquires in conjunction with the acquisition of a business represents the fair value assigned to incomplete research projects which, at the time of acquisition, have not reached technological feasibility. The amounts are capitalized and accounted for as indefinite-lived intangible assets, subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project, the asset is classified as a definite-lived intangible and the Company will make a determination as to the then-useful life of the intangible asset, generally determined by the period in which the substantial majority of the cash flows are expected to be generated, and begin amortization. The Company evaluates IPR&D for impairment at least annually, or more frequently if impairment indicators exist, by performing a quantitative test that compares the fair value of the IPR&D intangible asset with its carrying value. If the fair value is less than the carrying amount, an impairment loss is recognized in operating results. The Company believes no impairment of its acquired IPR&D existed as of December 31, 2022 or December 31, 2021. If we acquire an asset or group of assets that do not meet the definition of a business under applicable accounting standards, the acquired IPR&D is expensed on its acquisition date, unless it has an alternative future use. Future costs to develop these assets are recorded to research and development expense as they are incurred. In January 2021, in connection with our acquisition of Kleo, we recorded intangible assets consisting of F-12 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 2. Summary of Significant Accounting Policies (Continued) IPR&D assets of $18,400, which included an oncology therapeutic candidate entering Phase I clinical trials and a COVID-19 therapeutic candidate in the planning stage for clinical development, and goodwill of $1,390. See Note 6, "Acquisitions" for additional details. Impairment of Long-lived Assets The Company monitors its long-lived assets for indicators of impairment. If such indicators are present, the Company assesses the recoverability of affected assets by determining whether the carrying value of such assets is less than the sum of the undiscounted future cash flows of the assets. If such assets are found not to be recoverable, the Company measures the amount of such impairment by comparing the carrying value of the assets to the fair value of the assets, with the fair value generally determined based on the present value of the expected future cash flows associated with the assets. The Company believes no impairment of long-lived assets existed as of December 31, 2022 or December 31, 2021. Fair Value Measurements Certain assets of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1—Quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The carrying values of other current assets, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. Leases The Company determines if an arrangement contains a lease at the inception of a contract. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of the remaining future minimum lease payments. If the interest rate implicit in the Company’s leases is not readily determinable, the Company utilizes an estimate of its incremental borrowing rate based on market sources including interest rates for companies with similar credit quality for agreements of similar duration, determined by class of underlying asset, to discount the lease payments. The right-of-use assets also include lease payments made before commencement and exclude lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Leases with an initial term of 12 months or less are not recorded on the balance sheet. Lease expense for these short-term leases are expensed as incurred over the term of the lease. Certain real estate leases require additional payments including reimbursement for real estate taxes, common area maintenance and insurance, which are expensed as incurred as variable lease costs. Other real estate leases contain one fixed lease payment that includes real estate taxes, common area maintenance and insurance. These fixed payments are considered part of the lease payment and included in the right-of-use assets and lease liabilities. For its real estate leases, which are accounted for as operating leases, the Company has elected the practical expedient to include both the lease and non-lease components as a single component. In addition, payments made by the Company for improvements to the underlying asset, if the payment relates to an asset of the lessor, are recorded as prepaid rent within other non-current assets in the consolidated balance sheets prior to lease commencement and on commencement, reclassified to the right-of-use asset. As of December 31, 2022, the Company had restricted cash of $2,398 included in other non-current assets in the consolidated financial statements, which represents collateral held by banks for letters of credit issued in connection with the leased office space in Yardley, Pennsylvania and Cambridge, Massachusetts. All restricted cash is invested in time deposits. See Note 12, ‘‘Commitments F-13 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 2. Summary of Significant Accounting Policies (Continued) and Contingencies’’ for additional information on real estate leases. Research and Development Costs Research and development costs are expensed as incurred. Research and development expenses consist of costs incurred in performing research and development activities, including salaries, non-cash share-based compensation and benefits, third-party license fees, rent and operating expenses for leased lab facilities, and external costs of vendors engaged to conduct clinical development activities and clinical trials as well as to manufacture clinical trial materials. Non- refundable prepayments for goods or services that will be used or rendered for future research and development activities are deferred and capitalized. Such amounts are recognized as an expense as the goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered or the services rendered. The Company has entered into various research and development-related contracts. These agreements are cancellable, and related payments are recorded as research and development expenses as incurred. The Company records accruals for estimated ongoing research costs. When evaluating the adequacy of the accrued liabilities, the Company analyzes progress of the studies or clinical trials, including the phase or completion of events, invoices received and contracted costs. Certain judgments and estimates are made in determining the accrued balances at the end of any reporting period. Actual results could differ from the Company's estimates. The Company's historical accrual estimates have not been materially different from the actual costs. date of the grant and recognizes compensation expense of those awards, over the requisite service period, which is generally the vesting period of the respective award. Forfeitures are accounted for as they occur. Generally, the Company issues share options with only service-based vesting conditions and records the expense for these awards using the straight-line method. The Company classifies non-cash share-based compensation expense in its consolidated statement of operations in the same manner in which the award recipient's payroll costs are classified or in which the award recipient's service payments are classified. The fair value of each share option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The Company lacks a sufficient history of company-specific historical and implied volatility information for its shares. Therefore, it estimates its expected share price volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. The expected term of all of the Company's stock options has been determined utilizing the "simplified" method. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company has never paid cash dividends on common shares and does not expect to pay any cash dividends in the foreseeable future. Management evaluates its award grants and modifications and will adjust the fair value if any are determined to be spring-loaded. Foreign Currency Translation Share-Based Compensation for Periods Prior to the Separation The financial statements of our subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using period-end exchange rates for assets and liabilities, historical exchange rates for stockholders’ equity and weighted average exchange rates for operating results. Translation gains and losses are included in accumulated other comprehensive income, net of tax, in shareholders’ equity. Foreign currency transaction gains and losses are included in other expense in the consolidated statement of operations. The Company's aggregate foreign currency transaction losses were immaterial for the years ended December 31, 2022, 2021 and 2020. Share-Based Compensation The Company measures share options and restricted share unit awards granted to employees, non-employees, and directors based on the fair value on the Prior to the Separation from the Former Parent on October 3, 2022, certain of the Company’s employees have historically participated in the Former Parent’s non-cash share-based compensation plans. Non-cash share-based compensation expense for periods prior to the Separation has been allocated to the Company based on a combination of specific identification and a proportionate cost allocation method. Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the consolidated financial statements or in the Company's tax returns. Deferred tax assets and liabilities are determined on the basis of F-14 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 2. Summary of Significant Accounting Policies (Continued) the differences between the consolidated financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. The provision for income taxes includes the effects of applicable tax reserves, or unrecognized tax benefits, as well as the related net interest and penalties. Net Loss per Share Basic net loss per common share is calculated by dividing net loss by the weighted-average shares outstanding during the period. For purposes of the diluted net loss per share calculation, common share options are considered to be common share equivalents but have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share were the same for all periods presented. Net Loss per Share for Periods Prior to the Separation Net loss per share for periods prior to the Separation from the Former Parent was calculated based on the 39,375,944 shares of the Company's common shares distributed to the Former Parent's shareholders at the time of the Distribution, including common shares issued in connection with Former Parent share options that were exercised on October 3, 2022 and common shares issued in connection with Former Parent restricted share units that vested on October 3, 2022. The same number of shares is being utilized for the calculation of basic and diluted earnings per share for all periods presented prior to the Spin-Off. Concentrations of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist of cash, cash equivalents, and short-term debt securities. The Company maintains a portion of its cash deposits in government insured institutions in excess of government insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and has not experienced any losses on such accounts. The Company's cash management policy permits investments in U.S. federal government and federal agency securities, corporate bonds or commercial paper, supranational and sovereign obligations, certain qualifying money market mutual funds, certain repurchase agreements, and places restrictions on credit ratings, maturities, and concentration by type and issuer. The Company is exposed to credit risk in the event of a default by the financial institutions holding its cash in excess of government insured limits and in the event of default by corporations and governments in which it holds investments in cash equivalents and short-term debt securities, to the extent recorded on the consolidated balance sheet. Segment Information The Company manages its operations as a single segment, the development of therapies targeting neurological diseases, including rare disorders, for the purposes of assessing performance and making operating decisions. Consistent with our operational structure, the Company's chief decision maker manages and allocates resources at a consolidated level. Therefore, results of our operations are reported on a consolidated basis for the purposes of assessing performance and making operating decisions. In 2022 and 2021, materially all the Company's long-lived assets were held in the United States. Recently Adopted Accounting Pronouncements Effective January 1, 2022 the Company adopted ASU No. 2021- 04, Earnings Per Share (Topic 260), Debt—Modifications and Extinguishments (Subtopic 470-50), Compensation—Stock Compensation (Topic 718), and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call Options (a consensus of the Financial Accounting Standards Board ("FASB") Emerging Issues Task Force), which provides guidance on modifications or exchanges of a freestanding equity- classified written call option that is not within the scope of another topic. An entity should treat a modification of the terms or conditions or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange as an exchange of the original instrument for a new instrument, and provides further guidance on measuring the effect of a modification or an exchange of a freestanding equity-classified written call option that remains equity classified after modification or exchange. ASU 2021-04 also provides guidance on the recognition of the effect of a modification or an exchange of a freestanding equity- F-15 BIOHAVEN LTD.

The guidance has been applied prospectively and did not have a material effect on the consolidated financial statements of the Company. Recently Issued Accounting Pronouncements In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, to clarify the guidance in Topic 820 3. Marketable Securities when measuring the fair value of an equity security subject to contractual restrictions that prohibit the sale of an equity security. The ASU also introduced new disclosure requirements for equity securities subject to contractual sale restrictions that are measured at fair value in accordance with Topic 820. The amendments in ASU 2022-03 are effective for fiscal years beginning after December 15, 2023. The Company does not expect ASU No. 2022-03 to have a material effect on its consolidated financial statements.

Marketable Securities (Continued) Summarized below are the debt securities available-for-sale the Company held at December 31, 2022 that were in an unrealized loss position, aggregated by the length of time the investments have been in that position: December 31, 2022 Debt securities U.S. corporate bonds Foreign corporate bonds U.S. treasury bills U.S. agency bonds Total Less than 12 months Number of Securities Fair Value Unrealized Losses 16 $ 3 1 4 20 $ 104,508 $ 31,886 9,762 41,710 187,866 $ (135) (32) (5) (24) (196) The Company did not have any investments in a continuous unrealized loss position for more than twelve months as of December 31, 2022. The Company reviewed the securities in the table above and concluded that they are performing assets generating investment income to support the needs of the Company’s business. In performing this review, the Company considered factors such as the credit quality of the investment security based on research performed by external rating agencies and the prospects of realizing the carrying value of the security based on the investment’s current prospects for recovery. As of December 31, 2022, the Company did not intend to sell these securities and did not believe it was more likely than not that it would be required to sell these securities prior to the anticipated recovery of their amortized cost basis. Net Investment Income Sources of net investment income included in other expense, net under other income (expense) in the consolidated statements of operations for the years ended December 31, 2022 were as follows: Gross interest income from debt securities available-for-sale, money-market funds, and cash Investment expenses Net investment income 2022 3,235 (27) 3,208 $ $ The Company had no net investment income during the year ended December 31, 2021 and 2020. We utilize the specific identification method in computing realized gains and losses on sales of debt securities. The Company had no sales of debt securities during the years ended December 31, 2022, 2021 or 2020. 4. Fair Value of Financial Assets and Liabilities The preparation of the Company’s consolidated financial statements in accordance with GAAP requires certain assets and liabilities to be reflected at their fair value and others to be reflected on another basis, such as an adjusted historical cost basis. In this note, the Company provides details on the fair value of financial assets and liabilities and how it determines those fair values. Financial Instruments Measured at Fair Value on the Consolidated Balance Sheets Certain of the Company’s financial instruments are measured at fair value on the consolidated balance sheets on a recurring basis. The fair values of these instruments are based on valuations that include inputs that can be classified within one of three levels of a hierarchy established by GAAP. See Fair Value Measurements in Note 2, "Summary of Significant Accounting Policies" for a brief description of the type of valuation information (“valuation inputs”) that qualifies a financial asset or liability for each level. Financial assets measured at fair value on a recurring basis on the consolidated balance sheet at December 31, 2022 were as follows: F-17 BIOHAVEN LTD.

There were no securities transferred between Level 1, 2, and 3 during the year ended December 31, 2022. The following is a description, including valuation methodology, of the financial assets and liabilities measured at fair value on a recurring basis: Cash Equivalents Cash equivalents at December 31, 2022 consisted of cash invested in short-term money market funds and debt securities with an original maturity of 90 days or less at the date of purchase. The carrying value of cash equivalents approximates fair value as maturities are less than three months. When quoted prices are available in an active market, cash equivalents are classified in Level 1 of the fair value hierarchy. Fair values of cash equivalent instruments that do not trade on a regular basis in active markets are classified as Level 2. Marketable Securities The fair values of the Company’s Level 2 debt securities are obtained from quoted market prices of debt securities with similar characteristics, quoted prices from identical assets in inactive markets, or discounted cash flows to estimate fair value. On a quarterly basis, the Company compares the prices of its Level 2 debt securities to prices provided by a secondary source. Variances over a specified threshold are identified and reviewed to confirm the price provided by the primary source represents an appropriate estimate of fair value. The Company did not adjust any of the prices at December 31, 2022. Contingent Value Right Liability On January 4, 2021, the Company acquired Kleo Pharmaceuticals, Inc. (“Kleo”) (see Note 6 for additional information). Included in the purchase consideration transferred was a contingent value right to receive one dollar in cash for each Kleo share if certain specified Kleo biopharmaceutical products or product candidates receive the approval of the FDA prior to the expiration of 30 months following the effective time of the transaction. The maximum amount payable pursuant to the contingent value right is approximately $17,300, and the fair value of the contingent value right was $1,457 as of the acquisition date. The Company recorded the contingent value right in other non-current liabilities on the consolidated balance sheets. The fair value of the contingent value right was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The Company used a discounted cash flow approach to value the contingent value right liability. As inputs into the initial valuation, the Company considered the probability of FDA approval within the 30 months period, which we estimated at approximately 10%, the amount of the payment, and a discount rate of approximately 7% determined using an implied credit spread adjusted based on companies with similar credit risk. At December 31, 2021,the Company determined the value of the contingent value right to be immaterial and recognized a gain of $1,457 related to the contingent value right in other income (expense) in the consolidated statements of operations during the fourth quarter of 2021. The value of the contingent value right continues to be immaterial with no value included on the consolidated balance sheet as of December 31, 2022. F-18 BIOHAVEN LTD.

Fair Value of Financial Assets and Liabilities (Continued) Financial Instruments Not Measured at Fair Value on the Consolidated Balance Sheets The carrying value and estimated fair value classified by level of fair value hierarchy for financial instruments carried on the consolidated balance sheets at adjusted cost or contract value at December 31, 2022 and 2021 were as follows: December 31, 2022 Assets: Series A-2 Preferred Stock investment (1) December 31, 2021 Assets: Series A-2 Preferred Stock investment (1) Carrying Value Level 1 Fair Value Measurement Using: Level 3 Level 2 Total — 6,000 N/A N/A N/A N/A N/A N/A N/A N/A (1) It was not practical to estimate the fair value of this investment as it represents Series A-2 Preferred Stock of an unlisted company. On a routine basis the Company determined if additional preferred shares of the unlisted company had been issued and adjusted the carrying value of its Series A-2 Preferred Stock investment accordingly. The Series A-2 Preferred Stock investment was recorded in other non-current assets on the consolidated balance sheet at December 31, 2021. As of December 31, 2022, due to concerns related to Artizan's inability to fund its future operations, the Company determined its investment in Artizan to be fully impaired. Accordingly, the Company had no balance on its consolidated balance sheet relating to its investment in Artizan as of December 31, 2022. See Artizan under Note 11, "License Agreements" for additional details on the Series A-2 Preferred Stock investment. 5.

As of December 31, 2022, due to concerns related to Artizan's inability to fund its future operations, the Company determined its investment in Artizan to be fully impaired. Accordingly, during the fourth quarter of 2022 the Company recognized an impairment loss of $10,000 in other income (expense) on the consolidated statement of operations. See Note 11, “License Agreements” for additional details on the Artizan Agreement. Accrued Expenses and Other Current Liabilities Accrued expenses and other current liabilities consisted of the following: As of December 31, 2022 As of December 31, 2021 Accrued employee compensation and benefits Accrued clinical trial costs Other accrued expenses and other current liabilities Accrued expenses and other current liabilities $ $ 14,603 $ 17,788 11,715 9,538 24,051 3,571 44,106 $ 37,160 Contingently Redeemable Non-controlling Interest In September 2020, the Company's Asia-Pacific subsidiary, BioShin Limited (“BioShin”), authorized, issued and sold 15,384,613 BioShin Series A Preferred Shares at a price of $3.90 per share for a total of $60,000 to a group of investors led by OrbiMed, with participation from Cormorant Asset Management LLC, HBM Healthcare Investments Ltd, Surveyor Capital (a Citadel Company), and Suvretta Capital Management, LLC (the "BioShin Investors"). The BioShin Series A Preferred Shares contained both a call option by the Company and a put option held by the BioShin Investors. Due to the contingently redeemable features, the Company had classified the BioShin Series A Preferred Shares in mezzanine equity since the redemption was out of the Company's control. In November 2021, the Company, Biohaven Therapeutics Ltd. (“BTL”), Atlas Merger Sub and BioShin entered into an Agreement and Plan of Merger (the “BioShin Merger Agreement”). The BioShin Merger Agreement provided for the merger of Atlas Merger Sub with and into BioShin, with BioShin surviving the merger as a wholly owned indirect subsidiary of the Former Parent, in accordance with Section 233 of the Cayman Islands Companies Act. As a result of the satisfaction of the closing conditions described in the BioShin Merger Agreement, on January 6, 2022, each Series A convertible preferred share of BioShin, no par value, other than Excluded Shares (as defined in the BioShin Merger Agreement), was converted into the right to receive 0.080121 of the Former Parent’s common shares and was removed from mezzanine equity. No Series A convertible preferred shares of BioShin were outstanding following the closing. 6. Acquisitions On January 4, 2021, the Company acquired Kleo Pharmaceuticals, Inc. (“Kleo”). Kleo is a development-stage biopharmaceutical company focused on advancing the field of immunotherapy by developing small molecules that emulate biologics. The transaction was accounted for as the acquisition of a business using the acquisition method of accounting. The total fair value of the consideration transferred was $20,043 which primarily consisted of the issuance of a total of 115,836 common shares of the Former Parent to Kleo stockholders and contingent consideration in the form of a contingent value right to receive one dollar in cash for each Kleo share if certain specified Kleo biopharmaceutical products or product candidates receive the approval of the Food and Drug Administration (the "FDA") prior to the expiration of 30 months following the effective time of the transaction. The maximum amount payable pursuant to the contingent value right was approximately $17,300. At December 31, 2021, the Company determined the value of the contingent value right to be immaterial and recognized a gain of $1,457 related to the contingent value right in other income (expense) during the fourth quarter of 2021. The value of the contingent value right continues to be immaterial with no value included on the consolidated balance sheet as of December 31, 2022. Prior to the consummation of the transaction, the Company owned approximately 41.9% of the outstanding shares of Kleo and accounted for it as an equity method investment. As part of the transaction, the Company acquired the remainder of the shares of Kleo, and post-transaction the Company owns 100% of the outstanding shares of Kleo. The carrying value of the Company’s investment in Kleo was $1,176 immediately prior to the acquisition date. The Company determined the fair value of the existing interest was $6,437, and recognized a gain from its equity method investment during the first quarter of 2021 of $5,261 on the consolidated statement of operations as a result of remeasuring to fair value the existing equity interest in Kleo. In connection with the transaction, we recorded: net working capital of $573; property and equipment of $1,257; intangible assets consisting of in progress research and development assets of $18,400 which include an oncology therapeutic candidate entering F-20 BIOHAVEN LTD.

Acquisitions (Continued) Phase I clinical trials and a Multimodal Antibody Therapy Enhancer ("MATE") conjugation asset; debt assumed of $1,577; and goodwill of $1,390. Kleo’s employees, other than its President and Chief Financial Officer, were retained as part of the transaction. In connection with the transaction agreement, the Former Parent filed a registration statement permitting Kleo stockholders to offer and sell the common shares of the Former Parent issued in the transaction. Kv7 Platform Acquisition consolidated statement of operations for a regulatory milestone payment which became due to Knopp during the second quarter. Excluding the milestone payment noted above, the Company has not recorded any of the possible contingent consideration payments to Knopp as a liability in the accompanying consolidated balance sheet as none of the future events which would trigger a milestone payment were considered probable of occurring at December 31, 2022. 7. Shareholders' Equity Issuance of Common Shares in connection with the In April 2022, the Company closed the acquisition from Knopp Separation from the Former Parent Biosciences LLC (“Knopp”) of Channel Biosciences, LLC (“Channel”), a wholly owned subsidiary of Knopp owning the assets of Knopp’s Kv7 channel targeting platform (the “Kv7 Platform Acquisition”), pursuant to a Membership Interest Purchase Agreement (the “Purchase Agreement”), dated February 24, 2022. In consideration for the Kv7 Platform Acquisition, on April 4, 2022, the Company made an upfront payment comprised of $35,000 in cash and 493,254 common shares of the Former Parent, valued at approximately $58,747, issued through a private placement. The Company has also agreed to pay additional success-based payments comprised of (i) up to $325,000 based on developmental and regulatory milestones through approvals in the United States, EMEA and Japan for the lead asset, BHV-7000 (formerly known as KB-3061), (ii) up to an additional $250,000 based on developmental and regulatory milestones for the Kv7 pipeline development in other indications and additional country approvals, and (iii) up to $562,500 for commercial sales-based milestones of BHV-7000. Additionally, the Company has agreed to make scaled royalty payments in cash for BHV-7000 and the pipeline programs, starting at high single digits and peaking at low teens for BHV-7000 and starting at mid-single digits and peaking at low tens digits for the pipeline programs. The Company accounted for this purchase as an asset acquisition as substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset, IPR&D. The IPR&D asset has no alternative future use and relates to intellectual property rights related to the Kv7 platform lead, now BHV-7000. There was no material value assigned to any other assets or liabilities acquired in the acquisition. As such, during the second quarter of 2022, the Company recorded a charge to research and development ("R&D") expense in the accompanying consolidated statement of operations of $93,747. During the year ended December 31, 2022, the Company recorded $25,000 to R&D expense in the On October 3, 2022, the Former Parent completed the Distribution to holders of its common shares and the spin-off of Biohaven.

In the Distribution, an aggregate of 35,840,459 common shares of the Company were issued. The aggregate number of common shares issued in connection with the Distribution did not include 2,611,392 common shares to be issued in connection with Former Parent share options that were exercised on October 3, 2022 and 924,093 common shares to be issued in connection with Former Parent restricted share units that vested on October 3, 2022.

Non-Cash Share-Based Compensation 2022 Equity Incentive Plan In September 2022, the Company's shareholders approved the 2022 Equity Incentive Plan (the "2022 Plan"), which became effective on October 3, 2022. The 2022 Plan provides for the grant of incentive share options, nonstatutory share options, share appreciation rights, restricted share awards, restricted share unit awards ("RSUs"), performance-based share awards and other share-based awards. Upon the effectiveness of the 2022 Plan, there were 9,190,000 common shares reserved for issuance under the 2022 Plan. As of December 31, 2022, there were 166,250 shares of the Company's common shares available for future grants under the 2022 Plan. The number of shares reserved for issuance under the 2022 Plan automatically increases on January 1 of each calendar year by 4% of total common shares outstanding as of December 31 of the prior year, beginning October 3, 2022 through January 1, 2032. In In September 2022, the Company's shareholders approved the Legacy Equity Award Settlement Plan (the "Legacy Plan"), which became effective on September 29, 2022. The Legacy Plan is intended solely to provide for the grant and settlement of nonstatutory share options and RSUs, issued in respect of share options and RSUs originally granted pursuant to the Former Parent's 2017 Equity Incentive Plan and 2014 Equity Incentive Plan. On October 3, 2022, the Former Parent completed the Distribution and the Separation. Each Former Parent share option and RSU outstanding prior to the Distribution was converted into .5 stock options and RSUs in the Company. In total, 4,057,121 share options and 924,093 RSUs were granted and settled into 2,611,392 and 924,093 common shares, respectively, under the Legacy Plan on October 3, 2022. Non-Cash Share-Based Compensation Expense For periods prior to the Separation from the Former Parent, non- cash share-based compensation has been allocated to the Company by using a combination of specific identification and a proportionate cost allocation method based on employee hours or directly identified operating expenses, depending on the employee’s function. The amounts presented are not necessarily indicative of future awards and do not necessarily reflect the costs that the Company would have incurred as an independent company for the periods presented. Upon the effectiveness of the Company's Spin-off from the Former Parent, each Former Parent share option and RSU outstanding vested immediately (the "Acceleration") and converted into .5 share options and RSUs in the Legacy Plan in the Company. The non-cash share-based compensation expense related to the Acceleration was then allocated to the Company using the same methodology described above and recognized immediately, resulting in $101,440 of non-cash share-based compensation expense recognized related to to the Acceleration in the fourth quarter of 2022. The share options and RSUs granted under the Legacy Plan also immediately vested and settled as a result of the Spin-off, and the Company determined that no incremental compensation should be recognized related to these awards. Non-cash share-based compensation under the Former Parent’s non-cash share-based compensation plans was measured at the grant date based on the fair F-22 BIOHAVEN LTD.

Share Options All share option grants are awarded at fair value on the date of grant. The fair value of share options is estimated using the Black- Scholes option pricing model. Stock options generally expire 10 years after the grant date. The aggregate intrinsic value of share options is calculated as the difference between the exercise price of the share options and the fair value of the Company's common shares for those share options that had exercise prices lower than the fair value of the Company's common shares at December 31, 2022. The total intrinsic value of outstanding share options for the year ended December 31, 2022 was $61,639. The total intrinsic value of share options exercised for the year ended December 31, 2022 was $20,137.

Restricted Share Units The following table is a summary of the RSU activity for the year As discussed above, in connection with the Distribution, on October 3, 2022, 924,093 RSUs were granted and settled into 924,093 common shares under the Legacy Equity Award Settlement Plan. No additional RSUs were granted under the 2022 Plan during the year ended December 31, 2022. The Company’s RSUs are considered nonvested share awards and require no payment from the employee. For each RSU, employees receive one common share at the end of the vesting period. The employee can elect to receive the one common share net of taxes or pay for taxes separately and receive the entire share. Compensation cost is recorded based on the market price of the Company’s common shares on the grant date and is recognized on a straight-line basis over the requisite service period. As of December 31, 2022, there was no unrecognized compensation cost related to Company RSUs that are expected to vest. No fair value was assigned to the RSUs vested during the year ended December 31, 2022, as all RSUs vested were related to the RSUs granted and settled under the Legacy Equity Award Settlement Plan. ended December 31, 2022: Unvested restricted shares outstanding as of October 3, 2022 Granted Forfeited Vested Unvested restricted shares outstanding as of December 31, 2022 Number of Shares Weighted Average Grant Date Fair Value — $ 924,093 $ — $ (924,093) $ — $ — — — — — Employee Share Purchase Plan In September 2022, the Company's board of directors approved the rules and procedures of the 2022 Employee Share Purchase Plan (the "ESPP") approved by shareholders of the Company on September 28, 2022. Upon the effectiveness of the ESPP, 393,769 shares were authorized to be issued under purchase rights granted to eligible employees. The ESPP allows each eligible employee who is participating in the plan to purchase shares by authorizing payroll deductions of up to 15% of eligible earnings. Unless the participating employee has previously withdrawn from the offering, accumulated payroll deductions will be used to purchase shares on the last business day of the offering period at a price equal to 85% of the fair market value of the shares on the first business day or the last business day of the offering period, whichever is lower. Under applicable tax rules, an employee may purchase no more than $25 F-24 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 9. Non-Cash Share-Based Compensation (Continued) worth of ordinary shares, valued at the start of the offering period, under the ESPP in any calendar year. There is no minimum holding period associated with shares purchased pursuant to this plan. An employee’s purchase rights terminate immediately upon termination of employment. The number of shares reserved for issuance under the ESPP automatically increases on January 1 of each calendar year by 1% of total common shares outstanding as of December 31 of the prior year, beginning October 3, 2022 through January 1, 2032. As of December 31, 2022, 393,769 shares remained available for future issuance under the ESPP. In January 2023, 681,904 additional shares were authorized to be issued under the ESPP. The Company accounts for employee share purchases made under its ESPP using an estimate of the grant date fair value, which is determined in accordance with ASC 718, Stock Compensation. The purchase price discount and the look-back feature cause the ESPP to be compensatory and the Company to recognize compensation expense. The compensation cost is recognized on a straight-line basis over the requisite service period. The Company values ESPP shares using the Black-Scholes model. The Company did not recognize material compensation expense related to the ESPP for the year ended December 31, 2022. As of December 31, 2022, there was $221 of unrecognized non- cash share-based compensation expense related to the ESPP, which is expected to be recognized over the remaining offering period ending May 31, 2022. During the year ended December 31, 2022, no shares were issued under the ESPP. 10. Net Loss Per Share Basic and diluted net loss per share attributable to common shareholders of Biohaven Ltd. was calculated as follows: 2022 Year Ended December 31, 2021 2020 Numerator: Net loss attributable to Biohaven Ltd. Denominator: Weighted average common shares outstanding— basic and diluted (1) Net loss per share attributable to Biohaven Ltd.—basic and diluted $ (570,279) $ (213,796) $ (118,668) 44,741,316 39,375,944 39,375,944 $ (12.75) $ (5.43) $ (3.01) (1) Prior to the Spin-Off from the Former Parent on October 3, 2022, Biohaven Ltd. did not operate as an independent company. At the time of the Distribution, 39,375,944 shares of the Company's common stock were distributed to the Former Parent's shareholders, including common shares issued in connection with Former Parent share options that were exercised on October 3, 2022 and common shares issued in connection with Former Parent restricted share units that vested on October 3, 2022. This number of shares is being utilized for the calculation of basic and diluted earnings per share for all periods presented prior to the Spin-Off. The Company's potential dilutive securities include share options which have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common shareholders of the Company is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common shareholders for the periods indicated because including them would have had an anti-dilutive effect: Options to purchase common shares Year Ended December 31, 2022 8,959,215 11.

The Company was a co-obligor, jointly and severally with the Former Parent on its third-party long-term debt obligation under the Sixth Street Financing Agreement. The Former Parent’s third-party debt and related interest expense are not reflected in the consolidated financial statements because the Company had not agreed to pay a specified amount of the borrowings on the basis of its arrangement with the Former Parent, nor was the Company expected to pay any portion of the Former Parent’s third-party debt, and the borrowings were not specifically identifiable to the Company. On October 3, 2022, an affiliate of Pfizer, on behalf of the Former Parent, repaid in full all of the indebtedness and other obligations and liabilities owed by the Former Parent, including prepayment penalties. In connection with the termination and repayment in full of the indebtedness and other obligations and liabilities under the Sixth Street Financing Agreement, all related liens and security interests granted by or arising under the Sixth Street Financing Agreement were automatically released and discharged. Legal Proceedings From time to time, in the ordinary course of business, the Company is subject to litigation and regulatory examinations as well as information gathering requests, inquiries and investigations. As of December 31, 2022, there were no matters which would have a material impact on the Company’s financial results. 13. Income Taxes The income tax expense in the consolidated financial statements has been calculated on a separate return method and is presented as if the Company’s operations were separate taxpayers in the respective jurisdictions up to and including the Separation. Cash tax payments, income taxes receivable and deferred taxes, net of valuation allowance, are reflective of its actual tax balances prior and subsequent to the Distribution. As a company incorporated in the British Virgin Islands (“BVI”), the Company is principally subject to taxation in the BVI. Under the current laws of the BVI, the Company and all dividends, interest, rents, royalties, compensation and other amounts paid by the Company to persons who are not resident in the BVI and any capital gains realized with respect to any shares, debt obligations, or other securities of the Company by persons who are not resident in the BVI are exempt from all provisions of the Income Tax Ordinance in the BVI. The Former Parent historically outsourced all of the research and clinical development for its programs under a master services agreement with Biohaven Pharmaceuticals, Inc. (“BPI”). As a result of providing services under this agreement, BPI was profitable during the years ended December 31, 2022, 2021 and 2020, and BPI is subject to taxation in the United States. As such, in each reporting period, the Company's tax provision includes the effects of consolidating the results of operations of BPI. At December 31, 2022 and 2021, the Company continued to maintain a full valuation allowance against its net deferred tax assets, which are comprised primarily of capitalized research and development deductions, research and development tax credit carryforwards and net operating loss carryforwards, based on management’s assessment that it is more likely than not that the deferred tax assets will not be realized. The Company recorded an income tax provision during the years ended December 31, 2022, 2021 and 2020 of $438, $1,366 and $0 respectively, which primarily represents U.S. Federal and state taxes related to the Company’s profitable operations of BPI in the U.S. Loss before provision for income taxes consisted of the following: BVI Foreign Loss before provision for income taxes Year Ended December 31, 2021 (211,334) $ (1,096) 2022 (598,046) $ 28,205 2020 (123,468) 4,800 (569,841) $ (212,430) $ (118,668) $ $ The provision for income taxes consisted of the following: F-32 BIOHAVEN LTD.

The Company recorded a full valuation allowance against its Kleo deferred tax assets and periodically reviews its position. Due to Kleo's cumulative loss history, the Company determined that a full valuation allowance on these assets was appropriate. The Company will continue to evaluate the need for a valuation allowance on its deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of these allowances. As of December 31, 2022, and 2021, the Company had foreign net operating loss carryforwards of $69,214 and $39,281, respectively. As of December 31, 2022, and 2021, the Company had federal and state research and development and orphan drug credits of $60,340 and $26,590, respectively, which begin to expire in 2039. F-33 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 13. Income Taxes (Continued) Changes in the valuation allowance for deferred tax assets during the years ended December 31, 2022 and 2021 were due primarily to generation of nondeductible research expenses and tax credit carryforwards. Changes in the valuation allowance for deferred tax assets during the years ended December 31, 2021 and 2020 were due primarily to the acquisition of Kleo, an increase in the amount of carryforward tax credits for research and development, and an increase in future tax deductions for share awards to employees. Valuation allowance as of beginning of year Increases recorded to Purchase Accounting and Net Investment from Former Parent Increases recorded to income tax provision Valuation allowance as of end of year Year Ended December 31, 2021 2022 2020 $ 54,224 $ 32,970 $ 23,592 50,905 6,449 (1,089) 110,932 14,805 10,467 $ 216,061 $ 54,224 $ 32,970 The Company followed the authoritative guidance for recognizing and measuring uncertainty in income taxes for tax positions taken or expected to be taken in a tax return. The beginning and ending amounts of unrecognized tax benefits reconciles as follows: Year Ended December 31, 2021 2020 2022 Beginning of period balance $ 3,800 $ 2,700 $ 1,800 Increase for tax positions taken during the current period (Decreases) increases recorded to Purchase Accounting and Net Investment from Former Parent End of period balance — 50 — (1,600) 2,200 $ $ 1,050 3,800 $ 900 2,700 The unrecognized tax benefits relate primarily to issues common among multinational corporations. All of these unrecognized tax benefits, if recognized, would impact the Company's effective income tax rate. The Company's policy is to record interest and penalties related to income taxes, if any, as part of its income tax provision. As of December 31, 2022 and 2021, the total amount of accrued interest and penalties was not significant. BPI and Kleo file income tax returns in the U.S. and certain state jurisdictions. BPI’s U.S. federal and state income tax returns are subject to tax examinations for the tax year ended December 31, 2019 and subsequent years. The federal tax return for BPI is currently under audit by the IRS for the period ended December 31, 2019. 14. Related Party Transactions Relationship with the Former Parent Upon the effectiveness of the Separation on October 3, 2022, the Former Parent ceased to be a related party to the Company and accordingly, no related party transactions or balances are reported subsequent to October 3, 2022. On October 3, 2022, the Company entered into agreements with the Former Parent in connection with the Separation, including the following: Transition Services Agreement. The Company entered into a Transition Services Agreement with the Former Parent (the “Transition Services Agreement”) under which the Company or one of its affiliates will provide the Former Parent, and the Former Parent or one of its affiliates will provide the Company, with certain transition services for a limited time to ensure an orderly transition following the Spin-Off. The services that the Company and the Former Parent agreed to provide to each other under the Transition Services Agreement include certain finance, information technology, clinical study support, human resources and compensation, facilities, financial reporting and accounting and other services. The Company will pay the Former Parent, and the Former Parent will pay the Company, for any such services received by the Former Parent or the Company, as applicable, at agreed amounts as set forth in the Transition Services Agreement. Amounts received in connection with the Transition Services Agreement are recorded as other income on the consolidated statement of operations, as they are outside of the normal operating business of the Company. For the year ended December 31, 2022, the Company recorded $4,024 in other income reflecting transition services provided to the Former Parent, of which $2,748 was included as a receivable in other current assets on the consolidated balance sheet as of December 31, 2022. United States Distribution Services Agreement. The Company entered into a United States Distribution Services Agreement with the Former Parent, pursuant to which the Company shall continue to serve as the Former Parent’s distributor and agent for the distribution of the pharmaceutical product Nurtec ODT in the United States for a limited period of time following the Spin-Off. Under the Distribution Services F-34 BIOHAVEN LTD. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Amounts in thousands, except share and per share amounts) 14. Related Party Transactions (Continued) Agreement, the Former Parent and Pfizer Inc. have agreed to indemnify the Company for, among other things, losses resulting from the conduct of the distribution business or actions taken at the direction of the Former Parent. records of the Former Parent. The following disclosure summarizes activity between the Company and the Former Parent prior to the Separation, including the affiliates of the Former Parent that were not part of the Spin-Off. As the Company is acting as an agent of the Former Parent for Cost Allocations services performed under the Distribution Services Agreement, no amounts for revenues or expenses relating to the services performed thereunder are included on the Company's consolidated financial statements. As of December 31, 2022, the Company recorded restricted cash held on behalf of Former Parent of $35,212 and Due to Former Parent of $35,212 on the consolidated balance sheet primarily relating to cash held in connection with the execution of the Distribution Services Agreement which is legally payable to the Former Parent. Outsourcing & Employee Transfer Agreements. The Company entered into Outsourcing & Employee Transfer Agreements, one with Pfizer Inc., Bulldog (BVI) Ltd., the Former Parent and Biohaven Pharmaceuticals, Inc. (“U.S. Employer”), and the other with Pfizer Inc., Bulldog (BVI) Ltd., the Former Parent, and BioShin (Shanghai) Consulting Services Co., Ltd. (“Chinese Employer”), pursuant to which the Chinese Employer and the U.S. Employer will, among other things, provide Pfizer Inc. with the services of, and remain the employers of, certain of their employees for a limited period of time following the Spin-Off. During such period, Pfizer Inc. or one of its affiliates will pay the U.S. Employer for employee-related expenses for its employees (including the cost of salary and wages) and will pay the Chinese Employer a service fee based on employee-related expenses for its employees (including the cost of salary and wages). Amounts received in connection with the Outsourcing & Employee Transfer Agreements are recorded against their related operating expenses as they represent reimbursements for operating expenses incurred by the Company on behalf of the Former Parent. Relationship with the Former Parent prior to the Separation Pursuant to the Distribution Agreement, immediately prior to the Separation the Former Parent made a cash contribution to the Company which resulted in a cash balance of approximately $257,799 as of October 3, 2022. Prior to the Separation, the Company did not historically operate as a standalone business and the consolidated financial statements are derived from the consolidated financial statements and accounting The consolidated financial statements for periods prior to the Separation reflect allocations of certain expenses from the financial statements of the Former Parent, including research and development expenses and general and administrative expenses. These allocations include, but are not limited to, executive management, employee compensation and benefits, facilities and operations, information technology, business development, financial services (such as accounting, audit, and tax), legal, insurance, and non-cash share- based compensation. For periods prior to the Separation, these allocations to the Company are reflected in the consolidated statement of operations as follows: Research and development General and administrative Total Year Ended December 31, 2021 2022 2020 $ $ 146,521 $ 70,929 $ 33,482 82,744 229,265 $ 33,928 104,857 $ 14,646 48,128 Management believes these cost allocations are a reasonable reflection of services provided to, or the benefit derived by, the Company during the periods presented. The allocations may not, however, be indicative of the actual expenses that would have been incurred had the Company operated as a standalone public company. Actual costs that may have been incurred if the Company had been a standalone public company would depend on a number of factors, including the chosen organizational structure, what corporate functions the Company might have performed directly or outsourced and strategic decisions the Company might have made in areas such as executive management, legal and other professional services, and certain corporate overhead functions. Non-Cash Share-Based Compensation As discussed in Note 9, "Non-Cash Share-Based Compensation", prior to the Separation, Biohaven employees participated in the Former Parent’s non-cash share-based compensation plans, the costs of which, including those related to the Acceleration, have been allocated to the Company and recorded in research and development and general and administrative expenses F-35 BIOHAVEN LTD.

For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following events without Employee’s consent: (1) a material reduction in Employee's Base Salary; (2) a material reduction in Employee’s duties, authority and responsibilities relative to the Employee’s duties, authority, and responsibilities in effect immediately prior to such reduction; (3) the relocation of Employee’s principal place of employment, without Employee's consent, in a manner that lengthens his one-way commute distance by fifty (50) or more miles from his then-current principal place of employment immediately prior to such relocation; (4) any material breach of the Agreement by Biohaven or its successors; or (5) the liquidation, dissolution, merger, consolidation or reorganization of Biohaven or transfer of all or a significant portion of its business and/or assets, other than as a result of the Closing, unless the successor or successors shall have assumed all duties and obligations of Biohaven under the Agreement; provided, however, that, any such termination by Employee shall only be deemed for Good Reason pursuant to this definition if: (a) Employee gives Biohaven written notice to his supervisor of his intent to terminate for Good Reason within thirty (30) days following the occurrence of the condition(s) that he believes constitute(s) Good Reason, which notice shall describe such condition(s); (b) Biohaven fails to remedy such condition(s) within thirty (30) days following receipt of the written notice (the “Cure Period”); (c) Biohaven has not, prior to receiving such notice from Employee, already informed Employee that his employment with Biohaven is being terminated and (d) Employee voluntarily terminates his employment within thirty (30) days following the end of the Cure Period. 215 Church Street, New Haven, CT 06510 | Phone: 203-404-0410 | www.biohavenpharma.com -5- b. TERMINATION BY THE COMPANY WITHOUT JUST CAUSE OR RESIGNATION BY EMPLOYEE FOR GOOD REASON COINCIDENT WITH A CHANGE IN CONTROL. i.

Biohaven will pay the benefits as described in Sections 2(a)(ii)(l), 2(a)(ii)(2), and 2(a)(ii)(3).

Notwithstanding anything to the contrary set forth in any applicable equity incentive plans or award agreements, effective as of Employee’s Employment Termination Date, the vesting and exercisability of all unvested time-based vesting equity awards, including without limitation, unvested shares subject to the RSUs and Options, then held by Employee shall accelerate such that all shares become immediately vested and exercisable, if applicable, by Employee upon such termination and all Options held by Employee shall remain exercisable, if applicable, for twelve (12) months following Employee’s termination. With respect to any performance-based vesting equity award, such award shall continue to be governed in all respects by the terms of the applicable equity award documents. ii. For purposes of this Agreement, a “Change in Control” means the occurrence of any of the events set forth in clauses (i), (ii) or (iii) with respect to either of Biohaven or the Parent, or the event set forth in clause (v) with respect to Biohaven, in each case of the definition of Change in Control set forth in Biohaven’s 2017 Equity Incentive Plan, as may be amended from time to time. c. TERMINATION FOR JUST CAUSE OR VOLUNTARY TERMINATION. i. If Employee’s employment is terminated prior to the expiration of the Term for just cause or if Employee’s employment is terminated as set forth in Section 2(d)(ii) or (iii) hereof (not including a resignation for Good Reason), Employee shall NOT be entitled to receive any Severance Benefits (as defined in Section 2(a)(ii)) or Change in Control Severance Benefits (defined in Section 2(b)(i)) and will only be entitled to receive any accrued but unpaid portion of the applicable Base Salary, plus any accrued but unused vacation that has been earned by Employee as the date of such termination. ii. For the purposes hereof, Biohaven shall have “Just Cause” to terminate Employee’s employment hereunder as a result of Employee’s gross negligence, willful misconduct, conviction of a felony (including the entry of a plea of nolo contendere) for illegal or criminal behavior in carrying out his duties as required pursuant to the terms of the Agreement. 215 Church Street, New Haven, CT 06510 | Phone: 203-404-0410 | www.biohavenpharma.com -6- Notwithstanding any other provision contained herein, Biohaven shall have the right to terminate the Agreement and Employee’s employment without just cause, and Employee’s remedies hereunder in the event of such termination shall be limited to the Severance Benefits or Change in Control Severance Benefits, as applicable, set forth in Section 2(a)(ii) and 2(b)(i) hereof. d. EVENTS OF TERMINATION. This Agreement shall terminate on the earliest to occur of the following events: i. the expiration of the Term; ii. the mutual written agreement of Biohaven and Employee; iii. the voluntary termination of Employee other than as a result of a resignation for Good Reason (as defined in Section 2(a)(vi)); iv. the death of Employee or Employee’s retirement; v. termination on account of a Disability (as defined above); vi. the termination of Employee by Biohaven with or without Just Cause (as defined in Section 2(c)(ii)) upon giving written notice to Employee; or vii. for a termination for Good Reason, immediately upon Employee's full satisfaction of the requirements of Section 2(a)(vi) 3.
