15,126,226 Shares of Common Stock underlying the Pre-Funded Warrants and

15,544,041 Shares of Common Stock underlying the Common Warrants

We are offering on a firm commitment basis 417,815 shares of our common stock and 15,126,226 pre-funded warrants, together with common warrants to purchase 15,544,041 shares of our common stock (and the shares of common stock that are issuable from time to time upon exercise of the pre-funded warrants and the common warrants). The common warrants will be issued separately but must be purchased together with the common stock and/or the pre-funded warrants (as described below). The combined purchase price for each share of common stock and accompanying common warrant is $1.93 and for each pre-funded warrant and accompanying common warrant is $1.9299. The common warrants will be exercisable beginning on the date of issuance, at an exercise price of $3.86 per share, and will expire on the five-year anniversary of the initial exercisable date.

We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if such purchasers so choose, pre-funded warrants in lieu of shares of common stock that would otherwise result in any such purchaser’s beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. Each pre-funded warrant will be exercisable for one share of our common stock and will be exercisable at any time after its original issuance until exercised in full. The purchase price of each pre-funded warrant will be equal to the price at which a share of common stock are sold to the public in this offering, minus $0.0001, and the exercise price of each pre-funded warrant will be $0.0001 per share. For each pre-funded warrant we sell, the number of shares of common stock we are offering will be decreased on a one-for-one basis. This offering also relates to the shares of common stock issuable upon exercise of the common warrants or any pre-funded warrants sold in this offering.

In connection with this offering, we effected a 1-for-17 reverse stock split effective on July 26, 2023, pursuant to which every 17 shares of our issued and outstanding common stock were reclassified as one share of common stock. The reverse stock split had no impact on the par value of our common stock or the authorized number of shares of our common stock. Unless otherwise indicated, all share and per share information in this prospectus is adjusted to reflect the reverse stock split. However, our annual report on Form 10-K for the fiscal year ended June 30, 2022, filed on September 2, 2022, any subsequent quarterly report on Form 10-Q, and all other documents incorporated by reference into this prospectus that were filed prior to July 26, 2023, do not give effect to the reverse stock split.

Our common stock is listed on The Nasdaq Capital Market under the symbol “BNTC.” On August 8, 2023, the last reported sale price of our common stock on The Nasdaq Capital Market was $1.93 per share.

There is no established public trading market for the pre-funded warrants or the common warrants, and we do not expect a market to develop. In addition, we do not intend to apply for the listing of the pre-funded warrants or the common warrants on any national securities exchange. Without an active trading market, the liquidity of the pre-funded warrants or the common warrants will be limited.

You should read this prospectus, together with additional information described under the heading “Where You Can Find More Information,” carefully before you invest in any of our securities.

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 28.

Company Overview

We endeavor to become the leader in discovery, development, and commercialization of therapeutic agents capable of addressing significant unmet medical need via the application of the silence and replace approach to the treatment of genetic disorders.

Benitec Biopharma Inc. (“Benitec” or the “Company” or in the third person, “we” or “our”) is a clinical-stage biotechnology company focused on the advancement of novel genetic medicines with headquarters in Hayward, California. The proprietary platform, called DNA-directed RNA interference, or ddRNAi, combines RNA interference, or RNAi, with gene therapy to create medicines that facilitate sustained silencing of disease-causing genes following a single administration. The unique therapeutic constructs also enable the simultaneous delivery of wildtype replacement genes, facilitating the proprietary “silence and replace” approach to the treatment of genetically defined diseases. The Company is developing a silence and replace-based therapeutic (BB-301) for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD), a chronic, life-threatening genetic disorder.

BB-301 is a silence and replace-based genetic medicine currently under development by Benitec. BB-301 is an AAV-based gene therapy designed to permanently silence the expression of the disease-causing gene (to slow, or halt, the biological mechanisms underlying disease progression in OPMD) and to simultaneously replace the mutant gene with a wildtype gene (to drive restoration of function in diseased cells). This fundamental therapeutic approach to disease management is called “silence and replace.” The silence and replace mechanism offers the potential to restore the normative physiology of diseased cells and tissues and to improve treatment outcomes for patients suffering from the chronic, and potentially fatal, effects of OPMD. BB-301 has been granted Orphan Drug Designation in the United States and the European Union.

The targeted gene silencing effects of RNAi, in conjunction with the durable transgene expression achievable via the use of modified viral vectors, imbues the silence and replace approach with the potential to produce permanent silencing of disease-causing genes along with simultaneous replacement of the wild type gene function following a single administration of the proprietary genetic medicine. We believe that this novel mechanistic profile of the current and future investigational agents developed by Benitec could facilitate the achievement of robust and durable clinical activity while greatly reducing the frequency of drug administration traditionally expected for medicines employed for the management of chronic diseases. Additionally, the achievement of permanent gene silencing and gene replacement may significantly reduce the risk of patient non-compliance during the course of medical management of potentially fatal clinical disorders.

We will require additional financing to progress our product candidates through to key inflection points.

Our Strengths

We believe that the combination of our proprietary ddRNAi and silence and replace technology, and our deep expertise in the design and development of genetic medicines, will enable us to achieve and maintain a leading position in gene silencing and gene therapy for the treatment of human disease. Our key strengths include:

• A first mover advantage for silence and replace-based therapeutics;

• A proprietary ddRNAi-based silence and replace technology platform that may potentially enable the serial development of single-administration therapeutics capable of facilitating sustained, long-term silencing of disease-causing genes and concomitant replacement of wild type gene function;

• A proprietary AAV vector technology which improves the endosomal escape capability of virus produced in insect cells using a baculovirus system. This technology has broad application in AAV-based gene therapies;

• The capabilities to drive the development of a pipeline of programs focused on chronic diseases with either large patient populations, or rare diseases, which may potentially support the receipt of Orphan Drug Designation, including OPMD; and

• A growing portfolio of patents protecting improvements to our ddRNAi, and silence and replace, technology and product candidates through at least 2036, with additional patent life anticipated through at least 2040.

Our Strategy

We endeavor to become the leader in discovery, development, and commercialization of silence and replace-based therapeutic agents. We apply the following general strategy to drive the Company towards these goals:

• Selectively develop proprietary and partnered programs; and

• Continue to explore and secure research and development partnerships with global biopharmaceutical companies supported by the differentiated nature of our scientific platform and intellectual property portfolio.

Our senior leadership team will continue to explore partnership opportunities with global biopharmaceutical companies, as we expect the unique attributes of the proprietary ddRNAi and silence and replace approaches, and the breadth of potential clinical indications amenable to our proprietary methods, to support the formation of collaborations over a broad range of diseases with significant unmet medical need.

We seek to actively protect our intellectual property and proprietary technology. These efforts are central to the growth of our business and include:

• Seeking and maintaining patents claiming our ddRNAi and silence and replace technologies and other inventions relating to our specific products in development or that are otherwise commercially and/or strategically important to the development of our business;

• Protecting and enforcing our intellectual property rights; and

• Strategically licensing intellectual property from third parties to advance development of our product candidates.

Our Technology—ddRNAi and Silence and Replace

Our proprietary technology platforms are designated as DNA-directed RNA interference, or “ddRNAi”, and “silence and replace.” ddRNAi is designed to produce permanent silencing of disease-causing genes, by combining RNA interference, or RNAi, with viral delivery agents typically associated with the field of gene therapy (i.e., viral vectors). Modified AAV vectors are employed to deliver genetic constructs which encode short hairpin RNAs that are, then, serially expressed and processed to produce siRNA molecules within the transduced cell for the duration of the life of the target cell. These newly introduced siRNA molecules drive permanent silencing of the expression of the disease-causing gene. The silence and replace approach further bolsters the biological benefits of permanent silencing of disease-causing genes by incorporating multifunctional genetic constructs within the modified AAV vectors to create an AAV-based gene therapy agent that is designed to silence the expression of disease-causing genes (to slow, or halt, the underlying mechanism of disease progression) and to simultaneously replace the mutant genes with normal, “wildtype” genes (to drive restoration of function in diseased cells). This fundamentally distinct therapeutic approach to disease management offers the potential to restore the underlying physiology of the treated tissues and, in the process, improve treatment outcomes for patients suffering from the chronic and, potentially, fatal effects of diseases like Oculopharyngeal Muscular Dystrophy (OPMD).

Traditional gene therapy is defined by the introduction of an engineered transgene to correct the pathophysiological derangements derived from mutated or malfunctioning genes. Mutated genes can facilitate the intracellular production of disease-causing proteins or hamper the production of critical, life-sustaining, proteins. The introduction of a new transgene can facilitate the restoration of production of normal proteins within the diseased cell, thus, restoring natural biological function. Critically, the implementation of this traditional method of gene therapy cannot eliminate the expression, or the potential deleterious effects of, the underlying mutant gene (as mutant proteins may be continually expressed and aggregate or drive the aggregation of other native proteins within the diseased cell). In this regard, the dual capabilities of the proprietary silence and replace approach to silence a disease-causing gene via ddRNAi and simultaneously replace the wild type activity of a mutant gene via the delivery of an engineered transgene could facilitate the development of differentially efficacious treatments for a range of genetic disorders.

Overview of RNAi and the siRNA Approach

The mutation of a single gene can cause a chronic disease via the resulting intracellular production of a disease-causing protein (i.e., an abnormal form of the protein of interest), and many chronic and/or fatal disorders are known to result from the inappropriate expression of a single gene or multiple genes. In some cases, genetic disorders of this type can be treated exclusively by “silencing” the intracellular production of the disease-causing protein through well-validated biological approaches like RNA interference (“RNAi”). RNAi employs small nucleic acid molecules to activate an intracellular enzyme complex, and this biological pathway temporarily reduces the production of the disease-causing protein. In the absence of the disease-causing protein, normal cellular function is restored and the chronic disease that initially resulted from the presence of the mutant protein is partially or completely resolved. RNAi is potentially applicable to over 20,000 human genes and a large number of disease-causing microorganism-specific genes.

7

Figure 1. The siRNA Approach

A small double stranded RNA, or dsRNA, molecule (A, Figure 1), comprising one strand known as the sense strand and another strand known as the antisense strand, which are complementary to each other, is synthesized in the laboratory. These small dsRNAs are called small interfering RNAs, or siRNAs. The sequence of the sense strand corresponds to a short region of the target gene mRNA. The siRNA is delivered to the target cell (B, Figure 1), where a group of enzymes, referred to as the RNA-Induced Silencing Complex, or RISC, process the siRNA (C, Figure 1), where one of the strands (usually the sense strand) is released (D, Figure 1). RISC uses the antisense strand to find the mRNA that has a complementary sequence (E, Figure 1) leading to the cleavage of the target mRNA (F, Figure 1). As a consequence, the output of the mRNA (protein production) does not occur (G, Figure 1). Several companies, including Alnylam Pharmaceuticals Inc., utilize this approach in their RNAi product candidates.

Importantly, many genetic disorders are not amenable to the traditional gene silencing approach outlined in Figure 1, as the diseased cells may produce a mixture of the wildtype protein of interest and the disease-causing mutant variant of the protein, and the underlying genetic mutation may be too small to allow for selective targeting of the disease-causing variant of the protein through the use of siRNA-based approaches exclusively. In these cases, it is extraordinarily difficult to selectively silence the disease-causing protein without simultaneously silencing the wildtype intracellular protein of interest whose presence is vital to the conduct of normal cellular functions.

Our proprietary silence and replace technology utilizes the unique specificity and robust gene silencing capabilities of RNAi while overcoming many of the key limitations of siRNA-based approaches to disease management.

8

In the standard RNAi approach, double-stranded siRNA is produced synthetically and, subsequently, introduced into the target cell via chemical modification of the RNA or alternative methods of delivery. While efficacy has been demonstrated in several clinical indications through the use of this approach, siRNA-based approaches maintain a number of limitations, including:

• Clinical management requires repeat administration of the siRNA-based therapeutic agent for multiple cycles to maintain efficacy;

• Long-term patient compliance challenges due to dosing frequencies and treatment durations;

• Therapeutic concentrations of siRNA are not stably maintained as the levels of synthetic siRNA in the target cells decrease over time;

• Novel chemical modifications or novel delivery materials are typically required to introduce the siRNA into the target cells, making it complicated to develop a broad range of therapeutics agents;

• Potential adverse immune responses, resulting in serious adverse effects;

• Requirement for specialized delivery formulations for genetic disorders caused by mutations of multiple genes; and

• siRNA acts only to silence genes and cannot be used to replace defective genes with normally functioning genes.

Our Approach to the Treatment of Genetic Diseases—ddRNAi and Silence and Replace

Our proprietary silence and replace approach to the treatment of genetic diseases combines RNAi with wildtype gene replacement to drive permanent silencing of disease-causing genes and concomitant restoration of functional wildtype genes following a single administration of the therapeutic agent. Benitec employs ddRNAi in combination with classical gene therapy (i.e., transgene delivery via viral vectors) to overcome several of the fundamental limitations of RNAi.

The silence and replace approach to the treatment of genetic disorders employs adeno-associated viral vectors (“AAVs”) to deliver genetic constructs which may, after a single administration to the target tissues:

• Chronically express RNAi molecules inside of the target, diseased, cells (to serially silence the intracellular production of disease-causing protein and the wildtype protein of interest);

• Simultaneously drive the expression of a wildtype variant of the protein of interest (to restore native intracellular biological processes); and

• AAV vectors can accommodate the multi-functional DNA expression cassettes containing the engineered wildtype transgenes and the novel genes encoding short hairpin RNA/micro RNA molecules (shRNA/miRNA) that are required to support the development of therapeutic agents capable of the achievement of the goals of the silence and replace approach to therapy.

Our silence and replace technology utilizes proprietary DNA expression cassettes to foster continuous production of gene silencing shRNAs and wildtype proteins (via expression of the wildtype transgene). A range of viral gene therapy vectors can be used to deliver the DNA construct into the nucleus of the target cell and, upon delivery, shRNA molecules are expressed and subsequently processed by intracellular enzymes into siRNA molecules that silence the expression of the mutant, disease-causing protein (Figure 2).

In the silence and replace approach (Figure 2):

• A DNA construct is delivered to the nucleus of the target cell by a gene therapy vector (A) such as an AAV vector;

9

• Once inside of the nucleus, the DNA construct drives the continuous production of shRNA molecules (B) which are processed by an enzyme called Dicer into siRNAs (C);

• The processed siRNA is incorporated into RISC and silences the target gene using the same mechanism shown in Figure 1; and

• When the DNA expression cassette is additionally comprised of a wildtype transgene, upon entry of the DNA construct into the nucleus of the target cell via the use of the AAV vector, the DNA construct also drives the continuous production of wildtype protein (to restore native intracellular biological processes).

Figure 2. The Silence and Replace Approach

Our strategy is to discover, develop and commercialize treatments that leverage the capabilities of ddRNAi and the silence and replace approach to disease management.

For selected product candidates, at the appropriate stage, we may collaborate with large biopharmaceutical companies to further co-develop and, if approved, commercialize our ddRNAi-based and silence and replace-based products to achieve broad clinical and commercial distribution. For specific clinical indications that we deem to be outside of our immediate areas of focus, we will continue to out-license, where appropriate, applications of our ddRNAi and silence and replace technology to facilitate the development of differentiated therapeutics, which could provide further validation of our proprietary technology and approach to disease management.

Our cash and cash equivalents will be deployed for the advancement of our product candidate BB-301 for the treatment of OPMD-derived dysphagia, including the natural history lead-in study and the Phase 1b/2a BB-301 treatment study, for the continued advancement of development activities for other existing and new product candidates, for general corporate purposes and for strategic growth opportunities.

Oculopharyngeal Muscular Dystrophy—OPMD

OPMD is an insidious, autosomal-dominant, late-onset degenerative muscle disorder that typically presents in patients at 40-to-50 years of age. The disease is characterized by progressive swallowing difficulties (dysphagia) and eyelid drooping (ptosis). OPMD is caused by a specific mutation in the poly(A)-binding protein nuclear 1, or PABPN1, gene. OPMD is a rare disease; however, patients have been diagnosed with OPMD in at least 33 countries. Patient populations suffering from OPMD are well-identified, and significant geographical clustering has been noted for patients with this disorder, which could simplify clinical development and global commercialization efforts.

BB-301 is an AAV-based gene therapy designed to silence the expression of disease-causing genes (to slow, or halt, the underlying mechanism of disease progression) and to simultaneously replace the mutant genes with normal, “wildtype” genes (to drive restoration of function in diseased cells). This fundamental therapeutic approach to disease management is called “silence and replace” and this biological mechanism offers the potential to restore the underlying physiology of the treated tissues and, in the process, improve treatment outcomes for patients suffering from the chronic and, potentially, fatal effects of Oculopharyngeal Muscular Dystrophy (OPMD). BB-301 has been granted Orphan Drug Designation in the United States and the European Union.

Our Pipeline

The following table sets forth the key background information related to the current product candidate:

Table 1. BB-301 Background and Development Status

BB-301

We are developing BB-301 for the treatment of Oculopharyngeal Muscular Dystrophy (OPMD). The Investigational New Drug (IND) application for BB-301 was approved to proceed by the U.S. Food and Drug Administration in June 2023. BB-301 is the lead investigational agent under development by Benitec, and the key attributes of BB-301 are outlined in Figure 3.

11

Figure 3. Overview of BB-301

BB-301 is a first-in-class genetic medicine employing the “silence and replace” approach for the treatment of OPMD. OPMD is an insidious, autosomal-dominant, late-onset, degenerative muscle disorder that typically presents in patients at 40-to-50 years of age. The disease is characterized by progressive swallowing difficulties (dysphagia) and eyelid drooping (ptosis). OPMD is caused by a specific mutation in the poly(A)-binding protein nuclear 1 gene (PABPN1).

OPMD is a rare disease, however, patients have been diagnosed with OPMD in at least 33 countries. Patient populations suffering from OPMD are well-identified, and significant geographical clustering has been noted for patients with this disorder. Each of these attributes could facilitate efficient clinical development and global commercialization of BB-301.

PABPN1 is a ubiquitous factor that promotes the interaction between the poly(A) polymerase and CPSF (cleavage and polyadenylation specificity factor) and, thus, controls the length of mRNA poly(A) tails, mRNA export from the nucleus, and alternative poly(A) site usage. The characteristic genetic mutation underlying OPMD results in trinucleotide repeat expansion(s) within exon 1 of PABPN1 and results in an expanded poly-alanine tract at the N-terminal end of PABPN1. The mutation generates a protein with an N-terminal expanded poly-alanine tract of up to 18 contiguous alanine residues, and the mutant protein is prone to the formation of intranuclear aggregates designated as intranuclear inclusions (INIs). The INIs that sequester wildtype PABPN1 may contribute to the “loss of function” phenotype associated with OPMD.

No therapeutic agents are approved for the treatment of OPMD. Additionally, there are no surgical interventions available to OPMD patients that modify the natural history of the disease, which is principally comprised of chronic deterioration of swallowing function. BB-301 has received Orphan Drug Designation in the United States and the European Union and, upon achievement of regulatory approval for BB-301 in these respective jurisdictions, the Orphan Drug Designations would provide commercial exclusivity independent of intellectual property protection. While OPMD is a rare medical disorder, we believe the commercial opportunity for a safe and efficacious therapeutic agent in this clinical indication exceeds $1 billion over the course of the commercial life of the product.

Benitec has previously outlined the core IND-enabling studies required by global regulatory agencies to support the initiation of BB-301 clinical trials in OPMD patients, and these studies included a BB-301 Pilot

12

Dosing Study (the “Pilot Dosing Study”) in large animals and a classical 12-week GLP Toxicology and Biodistribution Study for BB-301. In these large animal studies, BB-301 was directly injected into the pharyngeal muscles known to underlie the morbidity and mortality which characterizes the natural history of OPMD in human subjects.

As referenced above, the BB-301 Pilot Dosing Study in large animals was the first of two IND-enabling studies conducted by Benitec. This study was carried out under the guidance of the scientific team at Benitec, with key elements of the design and execution of the study conducted in close collaboration with a team of experts in both medicine and surgery that have been deeply engaged in the treatment of OPMD patients for decades. The BB-301 Pilot Dosing Study and the GLP Toxicology and Biodistribution Study for BB-301 were conducted in canine subjects in order to:

• Support the validation and optimization of the newly designed route and method of BB-301 administration,

• Confirm the efficiency of vector transduction and transgene expression in the key tissue compartments underlying the morbidity and mortality that comprises the natural history of OPMD,

• Confirm the optimal BB-301 doses in advance of initiation of human clinical studies, and

• Facilitate the observation of key toxicological data-points.

The BB-301 Pilot Dosing Study was designed as an 8-week study in Beagle dogs to confirm the transduction efficiency of BB-301 upon administration via direct intramuscular injection into specific anatomical regions of the pharynx through the use of an open surgical procedure. The method and route of BB-301 administration was developed in collaboration with key surgical experts in the field of Otolaryngology to enhance the ability of treating physicians to accurately administer the AAV-based investigational agent to the muscles that underlie the characteristic deficits associated with disease progression in OPMD. It is important to note that prior BB-301 non-clinical studies in mice have reproducibly validated the robust biological activity achieved following direct intramuscular injection of the AAV-based agent. As an example, direct injection of BB-301 into the tibialis anterior muscles of A17 mice (i.e., the murine disease model for OPMD) facilitated robust transduction of the targeted skeletal muscle cells and supported complete remission of the OPMD disease phenotype in this animal model.

Benitec conducted the BB-301 Pilot Dosing Study in Beagle dog subjects to demonstrate that direct intramuscular injection of BB-301 via the use of a proprietary dosing device in an open surgical procedure could safely achieve the following goals:

• Biologically significant and dose-dependent levels of BB-301 tissue transduction (i.e., delivery of the multi-functional BB-301 genetic construct into the target pharyngeal muscle cells),

• Broad-based and dose-dependent expression of the three distinct genes comprising the BB-301 gene construct within the pharyngeal muscle cells, and

• Biologically significant levels of target gene knock-down (i.e., inhibition of the expression of the gene of interest) within the pharyngeal muscle cells.

The Pilot Dosing Study evaluated the safety and biological activity of two concentrations of BB-301 (1.0+E13 vg/mL and 3.0+E13 vg/mL) across three distinct doses (1.0+E13 vg/mL and 3.0+E13 vg/mL with a low injection volume, and 3.0+E13 vg/mL with a high injection volume) following direct intramuscular injection into the Hypopharyngeal (HP) muscles and the Thyropharyngeal (TP) muscles of Beagle dogs via the use of a proprietary delivery device employed in an open surgical procedure. The HP muscle in Beagle dogs corresponds to the Middle Pharyngeal Constrictor (MPC) muscle in human subjects, and the TP muscle in Beagle dogs corresponds to the Inferior Pharyngeal Constrictor (IPC) muscle in human subjects. BB-301 was injected

13

only on Day 1 of the Pilot Dosing Study, and the corresponding canine pharyngeal muscles were harvested for molecular analyses after 8 weeks of observation post-injection. BB-301 dosing was carried out independently by a veterinary surgeon and an Otolaryngologist with extensive experience regarding the provision of palliative surgical care for OPMD patients.

The key results of the molecular analyses for the BB-301 Pilot Dosing Study in Beagle dogs are summarized below:

Figure 4. Pharyngeal Muscle Tissue Transduction Levels Achieved by BB-301

As outlined in Figure 4, dose-dependent increases in BB-301 transduction were observed in the two key pharyngeal constrictor muscles of the Beagle dog subjects.

Regarding Gene Expression Levels Observed for BB-301 Within the Pharyngeal Muscle Tissues (Figure 5, Figure 6, Figure 7):

• BB-301 encodes two distinct siRNA species (i.e., siRNA13 and siRNA17) which are each, independently, capable of inhibiting (i.e., “silencing”) the expression of the mutant form of the PABPN1 protein and the wildtype (i.e., endogenous) form of the PABPN1 protein (importantly, the mutant form of the PABPN1 protein underlies the development, and progression, of OPMD).

• BB-301 also codes for a wildtype version of the PABPN1 protein whose intracellular expression is unaffected by the inhibitory activities of siRNA13 and siRNA17; this “codon optimized” transcript drives the expression of a PABPN1 protein (i.e., coPABPN1) which serves to replenish the endogenous form of the PABPN1 protein and to replace the mutant form of PABPN1 that underlies the development and progression of OPMD in diseased tissues.

• For comparative purposes, it should be noted that the average range of expression for wildtype PABPN1 within the pharyngeal muscle cells of Beagle dogs is 4.5 copies per cell-to-7.8 copies per cell.

Figure 7. coPABPN1 Expression Levels Achieved by BB-301 within Pharyngeal Muscle Tissues

Regarding Wildtype PABPN1 Silencing (i.e., target “knock-down”) Observed for BB-301 Within the Pharyngeal Muscle Tissues (Figure 8):

• As noted above, BB-301 encodes two distinct siRNA species (i.e., siRNA13 and siRNA17) which are each, independently, capable of inhibiting (i.e., “silencing”) the expression of all forms of the PABPN1 protein (siRNA13 and siRNA17 silence the expression of both wildtype PABPN1 (wtPABPN1) and mutant PABPN1).

• While the Beagle dog subjects treated in the BB-301 Pilot Dosing Study do not express mutant PABPN1, the level of BB-301-driven gene silencing for the PABPN1 target can be indirectly assessed in these study subjects due to the equivalent inhibitory effects of siRNA13 and siRNA17 on both wtPABPN1 and mutant PABPN1.

• Thus, the wtPABPN1 silencing activity observed in the BB-301 Pilot Dosing Study serves as a surrogate for the silencing activity that would be anticipated in the presence of mutant PABPN1.

• BB-301 has been evaluated in prior non-clinical studies in animals that express mutant PABPN1 and, as a result, manifest the symptomatic phenotype of OPMD; in the symptomatic animal model of OPMD (i.e. the A17 mouse model), the achievement of PABPN1 silencing levels of 31% inhibition (or higher) following BB-301 administration led to resolution of OPMD disease symptoms and the elimination of the histopathological hallmarks of OPMD.

Figure 8. PABPN1 Silencing (i.e., “target knock-down”) Achieved by BB-301 within Pharyngeal Muscle Tissues

The current proprietary method of BB-301 delivery to the key pharyngeal muscles of study subjects, and the proprietary molecular analytical methods employed to assay the pharyngeal muscle tissues of study subjects, with both methods having been developed by the Benitec team, led to the observation of broad-based transduction of the targeted pharyngeal muscle tissues (Figure 9, represents individual sections of the TP muscle following BB-301 dosing).

Figure 9. BB-301 Transduction Levels Achieved for Individual Sections of the TP Muscle Following BB-301 dosing

Following the disclosure of the positive interim BB-301 Pilot Dosing Study results, Benitec completed pre-CTA and pre-IND meetings with regulatory agencies in France, Canada, and the United States.

Summary of Regulatory Interactions:

• In June 2023 the U.S. Food and Drug Administration (FDA) cleared the Investigational New Drug (IND) application for BB-301 which allows dosing of BB-301 to begin for OPMD subjects that are eligible for enrollment into the Phase 1b/2a treatment study (described below).

Operational Updates

The key milestones related to the development of BB-301 for the treatment of OPMD, along with other corporate updates, are outlined below:

BB-301 Clinical Development Program Overview:

• The BB-301 clinical development program will be conducted in the United States and Canada, and the primary elements of the program are summarized below:

• The program will comprise approximately 76 weeks of follow-up which we anticipate will consist of:

• The OPMD Natural History (NH) Study: 6-month pre-treatment observation periods for the evaluation of baseline disposition and natural history of OPMD-derived dysphagia (swallowing impairment) in each study participant.

• Dosing with BB-301: 1-day of BB-301 dosing to initiate participation in the Phase 1b/2a single-arm, open-label, sequential, dose-escalation cohort study. BB-301 will be delivered directly to the pharyngeal muscles of each study subject.

• Phase 1b/2a Treatment Evaluation: 52-weeks of post-dosing follow-up for conclusive evaluation of the primary and secondary endpoints of the BB-301 Phase 1b/2a treatment study, with interim safety and efficacy results expected to be available at the end of each 90-day period following the administration of BB-301.

• The OPMD NH Study will characterize the level of dysphagia borne by each OPMD subject at baseline and assess subsequent progression of dysphagia via the use of the following quantitative radiographic measures (i.e., videofluoroscopic swallowing studies or “VFSS”). The VFSS outlined below collectively provide objective assessments of global swallowing function and the function of the pharyngeal constrictor muscles (i.e., the muscles whose functional deterioration drives disease progression in OPMD):

• Total Pharyngeal Residue %(C2-4)²

• Pharyngeal Area at Maximum Constriction (PhAMPC)

• Dynamic Imaging Grade of Swallowing Toxicity Scale (DIGEST)

• Vallecular Residue %(C2-4)², Pyriform Sinus Residue %(C2-4)², and Other Pharyngeal Residue %(C2-4)²

• Normalized Residue Ratio Scale (NRRS_v, NRRS_p)

• Pharyngeal Construction Ratio (PCR)

• The NH study will also employ clinical measures of global swallowing capacity and oropharyngeal dysphagia, along with two distinct patient-reported outcome instruments targeting the assessment of oropharyngeal dysphagia.

18

• Upon the achievement of 6-months of follow-up in the NH Study, participants will be eligible for enrollment into the BB-301 Phase 1b/2a treatment study.

• BB-301 Phase 1b/2a Treatment Study:

• This first-in-human (FIH) study will evaluate the safety and clinical activity of intramuscular doses of BB-301 administered to subjects with OPMD.

• The primary endpoint of the FIH study will be safety.

• Secondary endpoints are designed to determine the impact of BB-301 on swallowing efficiency, swallowing safety, and pharyngeal constrictor muscle function in subjects diagnosed with OPMD with dysphagia via the use of serial clinical and videofluoroscopic assessments. Critically, each of the clinical and videofluoroscopic assessments employed in the FIH study will be equivalent to those employed for the NH study to facilitate comparative clinical and statistical analyses.

• The primary and secondary endpoints will be evaluated during each 90-day period following BB-301 intramuscular injection (Day 1).

• The NH of dysphagia observed for each OPMD study participant, as characterized by the VFSS and clinical swallowing assessments carried out during the NH Study, will serve as the baseline for comparative assessments of safety and efficacy of BB-301 upon rollover from the NH Study onto the BB-301 Phase 1b/2a Treatment Study.

• In December 2022, Benitec began screening OPMD subjects at the lead clinical study site in the United States.

• In January 2023, Benitec announced the enrollment of the first OPMD subject into the NH Study.

• In June 2023, Benitec announced that 13 subjects have been enrolled into the NH study in the United States.

• The pace of enrollment of OPMD subjects into the NH Study at the U.S. clinical study site supports our central clinical development goals of: (1) administering BB-301 to OPMD subjects in 2H2023, and (2) disclosing interim safety and efficacy data in 2H2023 for subjects that have received BB-301.

Additional Regulatory Updates for the Clinical Development Program:

North America:

• Formal submission of the comprehensive NH Study trial package to the Research Ethics Board (REB) for the lead clinical study site in Canada was completed, and Benitec awaits the formal response from the REB.

• Approval of the NH Study trial package by the REB is required for clinical study site activation and OPMD patient screening and enrollment to begin in Canada.

Nasdaq Minimum Bid Price Requirement

On September 6, 2022, we received a letter from the Listing Qualifications Department of the Nasdaq Stock Market notifying us that the minimum bid price per share for our common stock fell below $1.00 for a period of 30 consecutive business days and therefore we did not meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2). The letter also states that we would be provided 180 calendar days, or until March 6, 2023, to regain compliance with the minimum bid price requirement. In accordance with Rule 5810(c)(3)(A), we can regain compliance if at any time during the 180-day period the closing bid price of our

19

common stock is at least $1.00 for a minimum of 10 consecutive business days. On March 7, 2023, Nasdaq notified the Company in writing that while the Company had not regained compliance with the minimum bid price requirement, it was eligible for an additional 180 calendar day period, or until September 5, 2023, to regain compliance with the minimum bid price requirement. On August 9, 2023, Nasdaq notified the Company in writing that Nasdaq has determined that for the 10 consecutive business days ended August 8, 2023, the closing bid price of the Company’s common stock has been at $1.00 per share or greater. Accordingly, the Company has regained compliance with Listing Rule 5550(a)(2).

Reverse Stock Split

On December 7, 2022, we received the approval of the requisite number of holders of the shares of our common stock to amend our certificate of incorporation to effect a reverse split of the shares of our common stock in the range of 1-for-5 to 1-for-20, with the exact ratio to be set within such range in the discretion of our board of directors without further approval or authorization of our stockholders (the “Reverse Stock Split”).

On July 26, 2023, in connection with this offering, we effected the Reverse Stock Split of our shares of common stock at a ratio of 1-for-17. No fractional shares of common stock were issued in connection with the Reverse Stock Split, and in lieu of any fractional shares to which a stockholder of record would otherwise be entitled as a result of the Reverse Stock Split, we rounded up to the nearest whole number of shares to which a stockholder was entitled. The Reverse Stock Split required that proportionate adjustments be made to the conversion rate, the per share exercise price and the number of shares issuable upon the vesting, exercise or conversion of outstanding derivative securities issued by us.

Unless noted otherwise, all information presented in this prospectus, including the share and per share information, reflects the Reverse Stock Split of our outstanding shares of common stock. However, our annual report on Form 10-K for the fiscal year ended June 30, 2022, filed on September 2, 2022, any subsequent quarterly report on Form 10-Q, and all other documents incorporated by reference into this prospectus that were filed prior to July 26, 2023, do not give effect to the reverse stock split.

Implications of Being a Smaller Reporting Company

We are a “smaller reporting company” and will remain a smaller reporting company while either (i) the market value of our stock held by non-affiliates was less than $250 million as of the last business day of our most recently completed second fiscal quarter or (ii) our annual revenue was less than $100 million during our most recently completed fiscal year and the market value of our stock held by non-affiliates was less than $700 million as of the last business day of our most recently completed second fiscal quarter. We may rely on exemptions from certain disclosure requirements that are available to smaller reporting companies, including many of the same exemptions from disclosure requirements as those that are available to emerging growth companies, such as reduced disclosure obligations regarding executive compensation in our registration statements, prospectus and our periodic reports and proxy statements. For so long as we remain a smaller reporting company, we are permitted and intend to rely on exemptions from certain disclosure and other requirements that are applicable to other public companies that are not smaller reporting companies.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider the risks and uncertainties described below, as well as those risk factors included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2022 and any subsequent Quarterly Report on Form 10-Q, together with all of the other information contained in this prospectus and incorporated by reference herein, including our consolidated financial statements and the related notes, before deciding to invest in our securities. The risks and uncertainties described below and in the documents incorporated by reference herein are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks actually occurs, our business, financial condition, results of operations and prospects could be materially and adversely affected, the trading price of our common stock could decline and you could lose all or part of your investment.

Risks Related to Our Financial Condition and Capital Requirements

Even if this offering is successful, we will need to continue our efforts to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain capital when needed may significantly curtail, delay or discontinue one or more of our research or development programs or the commercialization of any approved product candidates.

Developing ddRNAi products is expensive, and we expect our research and development expenses to increase substantially in connection with our ongoing activities, particularly as we advance our product candidates in preclinical studies and in future clinical trials and as we undertake preclinical studies of new product candidates.

As of June 30, 2022 and March 31, 2023, our cash and cash equivalents were $4.1 million and $6.6 million, respectively. We estimate that the net proceeds from this offering will be approximately $27.5 million ($31.6 million assuming the full exercise of the underwriter’s option to purchase additional common stock and/or common warrants), after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, and assuming we sell only shares of common stock in this offering and no exercise of the common warrants. We estimate that these net proceeds, together with our existing cash and cash equivalents, will be sufficient to fund our operations until approximately the third quarter of 2024. However, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, government grants or other third-party funding, strategic alliances and licensing arrangements or a combination of these approaches. In addition, because the length of time and activities associated with successful development of our product candidates is highly uncertain, we are unable to estimate the actual funds we will require for development and any approved marketing and commercialization activities. In any event, we will require additional capital to obtain regulatory approval for our product candidates and to commercialize any product candidates that receive regulatory approval.

Any additional fundraising efforts may divert our management from their day-to-day activities, which may compromise our ability to develop and commercialize our product candidates. In addition, we cannot guarantee that future financing will be available 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, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our common stock to decline. If we incur indebtedness, we may be required to agree to restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could compromise our ability to conduct our business. We could also seek financing through arrangements with collaborative partners at an earlier stage than would otherwise be desirable and we may be required to relinquish rights to some or all of our technologies or product candidates or otherwise agree to terms unfavorable to us.

28

If we are unable to obtain funding on a timely basis or 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 approved product candidates.

Our auditors’ report expresses substantial doubt about our ability to continue as a going concern.

Our independent auditors’ report on our June 30, 2022 consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2022 includes a statement expressing substantial doubt about our ability to continue as a going concern. We have recurring net losses, which have resulted in an accumulated deficit of $148.3 million as of June 30, 2022 and $163.2 million as of March 31, 2023. We have incurred a net loss of $18.2 million for the fiscal year ended June 30, 2022 and $14.9 million for the nine-month period ended March 31, 2023. At June 30, 2022 and March 31, 2023, we had cash and cash equivalents of $4.1 million and $6.6 million, respectively. The Company does not have adequate liquidity to fund its operations for the next 12 months without raising additional funds and the success of raising such additional capital is not solely within the control of the Company. These factors raise substantial doubt about our ability to continue as a going concern.

We will continue to seek to raise additional working capital through public equity, private equity or debt financings. If we fail to raise additional working capital, or do so on commercially unfavorable terms, it would materially and adversely affect our business, prospects, financial condition and results of operations, and we may be unable to continue as a going concern. Future reports from our independent registered public accounting firm may also contain statements expressing substantial doubt about our ability to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide additional funding to us on commercially reasonable terms, if at all.

Risk Relating to this Offering

You will experience immediate dilution as a result of this offering and may experience additional dilution in the future.

The public offering price for shares of our common stock and common warrants (or pre-funded warrants and common warrants in lieu thereof) offered hereby will be substantially higher than the net tangible book value per share of our common stock immediately after this offering. If you purchase common stock and common warrants (or pre-funded warrants and common warrants in lieu thereof) in this offering, you will incur substantial and immediate dilution in the net tangible book value of your investment. Net tangible book value per share represents the amount of total tangible assets less total liabilities, divided by the number of shares of our common stock then outstanding. To the extent that options, common warrants or pre-funded warrants that are currently outstanding are exercised, there will be further dilution to your investment. The common warrants that are currently outstanding contain an exercise price adjustment mechanism providing that certain issuances of common stock (or common stock equivalents), including issuances as a result of this offering, if made at a price lower than the existing exercise price of such outstanding common warrants of $11.22, would reset the exercise price to such lower price. Any such reset of the exercise price of the outstanding common warrants may make it more likely that such common warrants are exercised. See the section titled “Description of Securities – Existing Warrants” for additional information. Additionally, exercise of the pre-funded warrants or any of the common warrants offered hereby will also dilute your investment. We may also issue additional common stock, options and other securities in the future that may result in further dilution of your shares of our common stock.

29

There is no public market for the pre-funded warrants or the common warrants being offered by us in this offering.

There is no established public trading market for the pre-funded warrants or the common warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants or the common warrants on any national securities exchange or other nationally recognized trading system, including The Nasdaq Capital Market. Without an active market, the liquidity of the pre-funded warrants and the common warrants will be limited.

Holders of the pre-funded warrants or the common warrants offered hereby will have no rights as common stockholders with respect to the common stock underlying the pre-funded warrants or the common warrants, as applicable, until such holders exercise their pre-funded warrants or common warrants, as applicable, and acquire our common stock, except as otherwise provided in the pre-funded warrants or the common warrants, as applicable.

Until holders of the pre-funded warrants or the common warrants offered hereby acquire our common stock upon exercise of the pre-funded warrants or the common warrants, as applicable, holders of the pre-funded warrants or the common warrants offered hereby will have no rights with respect to the common stock underlying such pre-funded warrants or common warrants except as otherwise provided in the pre-funded warrants or the common warrants, as applicable. Upon exercise of the pre-funded warrants or the common warrants, as applicable, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

Provisions of the common warrants and the pre-funded warrants offered by this prospectus could discourage an acquisition of us by a third party.

In addition to the discussion of the provisions of our Certificate of Incorporation (as defined below), certain provisions of the common warrants and the pre-funded warrants offered by this prospectus could make it more difficult or expensive for a third party to acquire us. Such common warrants and pre-funded warrants prohibit us from engaging in certain transactions constituting “fundamental transactions” unless, among other things, the surviving entity assumes our obligations under the common warrants and the pre-funded warrants. These and other provisions of the common warrants and the pre-funded warrants offered by this prospectus could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.

The common warrants are speculative in nature.

The common warrants offered hereby do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price. Specifically, commencing on the initial exercisable date, holders of the common warrants may acquire the common stock issuable upon exercise of such common warrants at an exercise price of $3.86 per share. Moreover, following this offering, the market value of the common warrants is uncertain and there can be no assurance that the market value of the common warrants will equal or exceed their public offering price. There can be no assurance that the market price of the common stock will ever equal or exceed the exercise price of the common warrants and consequently, whether it will ever be profitable for holders of the common warrants to exercise the common warrants.

We may not receive any additional funds upon the exercise of the pre-funded warrants and the common warrants.

If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained therein is not available for the issuance of the shares of common stock to the holder, each pre-funded warrant and common warrant may be exercised by way of a cashless exercise, meaning that the holder

30

may not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of shares of our common stock determined according to the formula set forth in the pre-funded warrant or the common warrant, as applicable. Accordingly, we may not receive any additional funds upon the exercise of the pre-funded warrants or the common warrants. In addition, the pre-funded warrants have an exercise price of $0.0001 per share of common stock, and as a result we will not receive significant additional funds upon their exercise even if not a cashless exercise.

Significant holders or beneficial owners of our common stock may not be permitted to exercise warrants that they hold.

Holders of the pre-funded warrants and the common warrants will not be entitled to exercise any portion of any pre-funded warrants or common warrants which, upon giving effect to such exercise, would cause the aggregate number of shares of our common stock beneficially owned by the holder (together with its affiliates) to exceed a specified percentage of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants and the common warrants. As a result, you may not be able to exercise your pre-funded warrants or common warrants for shares of our common stock at a time when it would be financially beneficial for you to do so. In such circumstance, you could seek to sell your pre-funded warrants or common warrants to realize value, but you may be unable to do so in the absence of an established trading market for the pre-funded warrants or the common warrants.

We may fail to meet the listing standards of The Nasdaq Capital Market whether or not this offering occurs. Even if this offering occurs, this offering could cause our stock price to fall, which could result in us being delisted from The Nasdaq Capital Market. The Reverse Stock Split may not have the desired affect on our stock price and we may fail to meet The Nasdaq Capital Market’s listing standards. Failure to maintain the listing of our common stock with a U.S. national securities exchange could adversely affect the liquidity of our common stock.

Our common stock is currently listed on The Nasdaq Capital Market. In order to maintain that listing, we must satisfy minimum financial and other continued listing requirements and standards, including maintaining a minimum share price. For example, the current continued listing requirements of Nasdaq provide, among other things, that a company may be delisted if the bid price of its stock drops below $1.00 for a period of 30 consecutive business days.

On September 6, 2022, we received a letter from the Listing Qualifications Department of the Nasdaq Stock Market notifying us that the minimum bid price per share for our common stock fell below $1.00 for a period of 30 consecutive business days and that therefore we did not meet the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2). The letter also stated that we would be provided 180 calendar days initially, or until March 6, 2023, to regain compliance with the minimum bid price requirement, and in the event we did not regain compliance by such date, we may be eligible for additional time. We did not regain compliance with the minimum bid price requirement by March 6, 2023; however, on March 7, 2023, we received a letter from the Listing Qualifications Department of the Nasdaq Stock Market notifying us that we were eligible for an additional 180 calendar day period, or until September 5, 2023, to regain compliance. The determination was based on us meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market with the exception of the bid price requirement, and our written notice of our intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary. In accordance with Rule 5810(c)(3)(A), we had the ability to regain compliance if at any time during this additional time period the closing bid price of our common stock is at least $1.00 for a minimum of 10 consecutive business days. If compliance was not able to be demonstrated by September 5, 2023, then the Nasdaq Staff would have provided notice that our securities would have been subject to delisting. At such time, we would have been able to appeal the delisting determination to a Hearings Panel.

In connection with regaining compliance, on December 7, 2022, we received the approval of the requisite number of holders of the shares of our common stock to amend our Certificate of Incorporation to effect a

31

reverse split of the shares of our common stock with the exact ratio to be set in the discretion of our Board of Directors. On July 26, 2023, in connection with this offering, we effected the Reverse Stock Split of our shares of common stock at a ratio of 1-for-17. No fractional shares of common stock were issued in connection with the Reverse Stock Split, and in lieu of any fractional shares to which a stockholder of record would otherwise be entitled as a result of the Reverse Stock Split, we rounded up to the nearest whole number of shares to which a stockholder was entitled. The Reverse Stock Split required that proportionate adjustments be made to the conversion rate, the per share exercise price and the number of shares issuable upon the vesting, exercise or conversion of outstanding derivative securities issued by us. On August 9, 2023, Nasdaq notified us in writing that Nasdaq has determined that for the 10 consecutive business days ended August 8, 2023, the closing bid price of our common stock has been at $1.00 per share or greater. Accordingly, we have regained compliance with Listing Rule 5550(a)(2).

If we fail to satisfy the continued listing requirements of Nasdaq, such as the minimum share price requirement, Nasdaq may take steps to delist our securities. Such a delisting would likely have a negative effect on the price and liquidity of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we would take actions to restore our compliance with Nasdaq’s listing requirements, but we can provide no assurance that any such action taken by us would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our securities, prevent our common stock from dropping below the Nasdaq minimum share price requirement or prevent future non-compliance with Nasdaq’s listing requirements.

If our common stock were to be delisted from Nasdaq, our common stock could begin to trade on one of the markets operated by OTC Markets Group, including OTCQX, OTCQB or OTC Pink (formerly known as the “pink sheets”), as the case may be. In such event, our common stock could be subject to the “penny stock” rules which, among other things, require brokers or dealers to approve investors’ accounts, receive written agreements and determine investor suitability for transactions and disclose risks relating to investing in the penny stock market. Any such delisting of our common stock could have an adverse effect on the market price of, and the efficiency of the trading market for our common stock, not only in terms of the number of shares that can be bought and sold at a given price, but also through delays in the timing of transactions and less coverage of us by securities analysts, if any. Also, if in the future we were to determine that we need to seek additional equity capital, it could have an adverse effect on our ability to raise capital in the public or private equity markets. In addition, there can be no assurance that our common stock would be eligible for trading on any such alternative exchange or markets.

There can be no assurance that the market price per new share of our common stock after the Reverse Stock Split will remain unchanged or increase in proportion to the reduction in the number of old shares of the Company’s common stock outstanding before the Reverse Stock Split. The liquidity of the shares of our common stock may be affected adversely by any reverse stock split given the reduced number of shares of the Company’s common stock that will be outstanding following the Reverse Stock Split. Further, no assurance can be given that we will be able to comply with the listing standards that we are required to meet in order to maintain a listing on such exchange and no assurance can be given that the price of our common stock will not again be in violation of Nasdaq’s minimum bid price rule in the future. Our failure to meet these requirements may result in our securities being delisted from Nasdaq.

Following the Reverse Stock Split, the resulting market price of our common stock may not attract new investors and may not satisfy the investing requirements of those investors. Consequently, the trading liquidity of our common stock may not improve. Although we believe that a higher market price of our common stock may help generate greater or broader investor interest, there can be no assurance that the Reverse Stock Split will result in a share price that will attract new investors, including institutional investors. In addition, there can be no assurance that the market price of our common stock will satisfy the investing requirements of those investors. As a result, the trading liquidity of our common stock may not necessarily improve.

32

Future sales of our common stock, or the perception that such sales may occur, could depress the trading price of our common stock.

After the completion of this offering, we expect to have 2,063,766 shares of our common stock outstanding (before giving effect to the exercise of any pre-funded warrants or common warrants offered hereby and subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split), which may be resold in the public market immediately after this offering. We and all of our directors and executive officers have signed lock-up agreements for a period of 90 days following the date of this prospectus, subject to specified exceptions. See “Underwriting.”

The underwriter may, in its sole discretion and without notice, release all or any portion of the shares of our common stock subject to lock-up agreements. As restrictions on resale end, the market price of our common stock could drop significantly if the holders of these shares of our common stock sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our common stock or other securities.

We have broad discretion in the use of the net proceeds we receive from this offering and may not use them effectively.

Our management will have broad discretion in the application of the net proceeds we receive in this offering, including for any of the purposes described in the section entitled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether our management is using the net proceeds appropriately. Because of the number and variability of factors that will determine our use of our net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business and cause the price of our common stock to decline. Pending their use, we may invest our net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders.

33

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $27.5 million, or $31.6 million if the underwriter exercises its option to purchase additional shares of common stock and/or common warrants in full, after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us and assuming no sale of any pre-funded warrants in this offering and no exercise of the common warrants.

We will only receive additional proceeds from the exercise of the common warrants issuable in connection with this offering if such warrants are exercised at their exercise price of $3.86 and the holders of such warrants pay the exercise price in cash upon such exercise.

We intend to use the net proceeds from this financing to support the clinical development of BB-301, including the natural history lead-in study and the Phase 1b/2a BB-301 treatment study, for the continued advancement of development activities for other existing and new product candidates, for general corporate purposes and for strategic growth opportunities.

The amount and timing of these expenditures will depend on a number of factors, including the progress of our research and development efforts, the progress of any partnering efforts, technological advances and the competitive environment for our product candidates. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that the proceeds will be used in a way that does not yield a favorable, or any, return for us. Pending application of the net proceeds as described above, we intend to invest the proceeds in investment-grade interest-bearing instruments, or will hold the proceeds in interest-bearing or non-interest-bearing bank accounts.

34

CAPITALIZATION

The following table sets forth our cash and cash equivalents and capitalization, each as of March 31, 2023:

• on an actual basis; and

• on an as adjusted basis to give effect to the issuance of shares of common stock and pre-funded warrants in the offering at a public offering price of $1.93 per share of common stock and common warrant and $1.9299 per pre-funded warrant and common warrant, assuming the exercise in full of all pre-funded warrants and assuming no exercise of any common warrants in this offering and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

You should consider this table in conjunction with the section titled “Summary Consolidated Financial Data” included herein and our financial statements and the notes to those financial statements and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2022, which are incorporated by reference herein. The as adjusted information set forth in the table below is illustrative only and will be adjusted based on the actual public offering price and other terms of this offering determined at pricing.

	As of March 31, 2023
	pro forma

The number of shares in the table above is based on 1,645,951 shares of common stock outstanding as of March 31, 2023, after giving effect to the Reverse Stock Split at a ratio of 1-for-17 which became effective on July 26, 2023 (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split) and does not include as of March 31, 2023:

• 45,199 shares of common stock issuable upon exercise of stock options outstanding (subject to adjustment based on the rounding down of fractional shares resulting from the Reverse Stock Split) at a weighted-average exercise price of $107.95 per share after giving effect to the Reverse Stock Split;

• 1,753,503 shares of common stock issuable upon the exercise of common warrants issued on September 15, 2022 exercisable for shares of common stock outstanding (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split) at an exercise price of $11.22 per share after giving effect to the Reverse Stock Split (with such warrants also containing an exercise price adjustment mechanism providing that certain issuances of common stock (or common stock equivalents), including issuances in this offering, if made at a price lower than such exercise price, would reset the exercise price to such lower price);

• 6,300 shares of common stock issuable upon the exercise of common warrants exercisable for shares of common stock outstanding (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split) at an exercise price of $178.50 per share after giving effect to the Reverse Stock Split; and

35

• 588,236 shares of common stock issuable upon the exercise of pre-funded warrants issued on September 15, 2022 exercisable for shares of common stock outstanding at an exercise price of $0.0017 per share after giving effect to the Reverse Stock Split.

Unless otherwise indicated, all information in this prospectus gives effect to the Reverse Stock Split (on a per share basis) and assumes no purchaser elects to purchase pre-funded warrants, no exercise of the common warrants and no exercise by the underwriter of its option to purchase additional shares and/or common warrants. However, our annual report on Form 10-K for the fiscal year ended June 30, 2022, filed on September 2, 2022, any subsequent quarterly report on Form 10-Q, and all other documents incorporated by reference into this prospectus that were filed prior to July 26, 2023, do not give effect to the reverse stock split.

36

DILUTION

If you invest in our common stock and/or pre-funded warrants in this offering, your ownership interest will be diluted immediately to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock after this offering. Our net tangible book value as of March 31, 2023 was approximately $4.124 million, or $2.506 per share of our common stock (based upon 1,645,951 shares of our common stock outstanding after giving effect to the Reverse Stock Split). Net tangible book value per share is equal to our total tangible assets less our total liabilities, divided by the number of shares of our outstanding common stock.

After giving effect to the sale of shares of our common stock and pre-funded warrants and accompanying common warrants in this offering at the public offering price of $1.93 per share, and assuming the exercise of all of the pre-funded warrants and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, and assuming no exercise of the common warrants, our as adjusted net tangible book value as of March 31, 2023 would have been approximately $31.588 million, or $1.84 per share of common stock. This represents an immediate decrease in as adjusted net tangible book value of $0.67 per share to our existing stockholders, and an immediate dilution of $0.09 per share to new investors purchasing securities in this offering at the public offering price.

The following table illustrates this dilution on a per share basis:

Public offering price per share and accompanying common warrant			$	1.93
Historical net tangible book value per share as of March 31, 2023	$	2.506
Pro forma decrease in net tangible book value per share attributable to investors in this offering		$0.67
As adjusted net tangible book value per share after giving effect to this offering			$	1.84
Dilution per share to new investors purchasing in this offering			$	0.09

The foregoing discussion and table do not take into account further dilution to investors in this offering that could occur upon the exercise of outstanding options, pre-funded warrants and warrants, including the pre-funded warrants and common warrants offered in this offering.

The discussion and table above are based on 1,645,951 shares of our common stock outstanding as of March 31, 2023, after giving effect to the Reverse Stock Split at a ratio of 1-for-17 which became effective on July 26, 2023 (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split), and do not include as of March 31, 2023:

• 15,544,041 shares of common stock that may be issued upon exercise of common warrants issued in this offering;

• 45,199 shares of common stock issuable upon exercise of stock options outstanding (subject to adjustment based on the rounding down of fractional shares resulting from the Reverse Stock Split) at a weighted-average exercise price of $107.95 per share after giving effect to the Reverse Stock Split;

• 1,753,503 shares of common stock issuable upon the exercise of common warrants issued on September 15, 2022 exercisable for shares of common stock outstanding (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split) at an exercise price of $11.22 per share after giving effect to the Reverse Stock Split (with such warrants also containing an exercise price adjustment mechanism providing that certain issuances of common stock (or common stock equivalents), including issuances in this offering, if made at a price lower than such exercise price, would reset the exercise price to such lower price);

37

• 6,300 shares of common stock issuable upon the exercise of common warrants exercisable for shares of common stock outstanding (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split) at an exercise price of $178.50 per share after giving effect to the Reverse Stock Split; and

• 588,236 shares of common stock issuable upon the exercise of pre-funded warrants issued on September 15, 2022 exercisable for shares of common stock outstanding at an exercise price of $0.0017 per share after giving effect to the Reverse Stock Split.

To the extent that our outstanding options, pre-funded warrants or warrants are exercised, new options are issued under our equity incentive plan, or additional shares of our common stock are issued in the future, there may be further dilution to investors participating in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

38

MARKET PRICE OF OUR COMMON STOCK AND RELATED STOCKHOLDER MATTERS

Our common stock trades on Nasdaq under the symbol “BNTC.” We do not intend to apply for the listing of the pre-funded warrants or the common warrants that are part of this offering on any national securities exchange. On August 8, 2023, the closing sale price of our common stock as reported on Nasdaq was $1.93 per share.

As of June 30, 2023, we had approximately 3,325 record holders of our common stock. The number of record holders is based on the actual number of holders registered on the books of our transfer agent and does not reflect holders of shares in “street name” or persons, partnerships, associations, corporations or other entities identified in security position listings maintained by depository trust companies.

39

EXECUTIVE COMPENSATION

As a “smaller reporting company” we have opted to comply with the scaled executive compensation disclosure rules applicable to “smaller reporting companies” (as such term is defined under applicable securities laws).

Our named executive officers, or our “NEOs”, for the fiscal year ended June 30, 2023 were Dr. Jerel A. Banks, our Executive Chairman and Chief Executive Officer, and Megan Boston, our Executive Director.

The Company’s named executive officer compensation program is designed to incentivize our named executive officers to grow our business and further link the interests of our named executive officers with our stockholders. We provide our named executive officers with an annual base salary as a fixed, stable form of compensation, certain cash incentive opportunities as noted below to reward achievement of short-term goals, and, in prior fiscal years, we have granted our named executive officers stock options with multi-year vesting schedules to further align their compensation with our stockholders’ long-term interests. We have also entered into employment agreements with our named executive officers that provide for a fixed notice period in connection with certain terminations of employment. The employment agreements and our named executive officer compensation program generally are described in greater detail below under the heading “Narrative Disclosure to Summary Compensation Table”.

The discussion of our compensation program prior to the completion of the re-domiciliation of Benitec Limited (“Limited”), resulting in the Company becoming the ultimate parent company of the Benitec group of companies (the “Re-Domiciliation”) reflects the compensation program of Limited, and of the Company for periods following the completion of the Re-Domiciliation. This discussion may contain forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs.

Narrative Disclosure to Summary Compensation Table

Annual Base Salary

We use base salaries to recognize the experience, skills, and responsibilities required of all of our employees, including our NEOs. Base salaries are reviewed annually by our Board. On October 12, 2022, the Compensation Committee approved increases of Dr. Banks’ and Ms. Boston’s annual base salaries to $546,000 and $333,427.50, respectively, each effective as of October 1, 2022 (Ms. Boston’s salary as reported on Form 8-K has been converted from AUD $1.00 to USD $0.73, and is $287,752.50 using a conversion rate of AUD $1.00 to USD $0.63, which was the conversion rate as of October 12, 2022).

Bonus Compensation

We have historically awarded our NEOs annual discretionary bonuses. For the fiscal year ended June 30, 2022, the Compensation Committee paid discretionary bonuses to our NEOs which were based on a target of 50% and 40% of base salary for each of Dr. Banks and Ms. Boston, respectively. The actual annual cash bonuses awarded to our NEOs for fiscal year ended June 30, 2022 performance are set forth above in the “Summary Compensation Table” in the column titled “Bonus.”

In respect of the fiscal year ended June 30, 2023, target annual bonuses for each of Dr. Banks and Ms. Boston remained unchanged, at 50% and 40% of annual base salary, respectively. The actual amount of annual discretionary bonuses for the fiscal year ended June 30, 2023 is not calculable through the latest practicable date. The Compensation Committee expects to determine such bonuses in October 2023, and the amounts of these bonuses will be disclosed in a filing by the Company in a Current Report on Form 8-K under Item 5.02(f) once the amounts are determined.

Equity or Equity-Linked Incentive Awards

Although we do not have a formal policy with respect to the grant of equity incentive awards to our NEOs, we believe that equity grants provide our NEOs with a strong link to our long-term performance, create an ownership culture and help to align the interests of our NEOs and our stockholders.

On December 9, 2020, the Company’s stockholders approved the Company’s 2020 Equity and Incentive Compensation Plan (the “2020 Plan”). Our Compensation Committee has granted stock options to our NEOs, which have historically been subject to time-based vesting, vesting in increments of one-third on each of the first, second and third anniversaries of the applicable grant date, generally subject to the applicable NEO’s continued employment through the vesting date. We believe that equity grants with a time-based vesting feature promote executive retention because this feature incentivizes our NEOs to remain in our employment during the vesting period.

41

On June 13, 2023, the Compensation Committee approved the grant to each of Dr. Banks and Ms. Boston, of nonqualified stock options to purchase 20,994 and 9,000 shares (reflective of the Reverse Stock Split), respectively, of the Company’s common stock pursuant to the 2020 Plan. The stock options vest in increments of one-third on each of the first, second and third anniversaries of the applicable grant date. If an NEO dies or terminates employment or service due to Disability (as defined in the 2020 Plan), the NEO generally has 12 months to exercise their vested options or the options are cancelled. If an NEO otherwise leaves the Company, other than for a termination by the Company for Cause (as defined in the 2020 Plan), the NEO generally has 90 days to exercise their vested options or the options are cancelled. Upon the consummation of a Change in Control (as defined in the 2020 Plan), all unvested stock options will immediately vest as of immediately prior to the Change in Control.

Employment Agreements with our NEOs.

We are a party to employment agreements with each of our NEOs. These employment agreements provide for “at will” employment and may be terminated at any time.

Employment Agreement with Dr. Jerel A. Banks, M.D. Ph.D.

(3) The option awards were granted under the Benitec Officers’ and Employees’ Share Option Plan prior to the Re-Domiciliation (the “Share Option Plan”). The share amounts and exercise prices of the awards shown in this table have been adjusted to reflect the terms of the Re-Domiciliation.

Other Elements of Compensation

Other Benefits and Perquisites

We offer participation in broad-based retirement, health and welfare plans to all of our colleagues, including our NEOs.

43

We maintain a tax-qualified defined contribution retirement plan that provides eligible U.S. employees (including Dr. Banks) with an opportunity to save for retirement on a tax-advantaged basis. Plan participants are eligible to defer eligible compensation subject to applicable annual Internal Revenue Code limits. The 401(k) plan is intended to be qualified under Section 401(a) of the Internal Revenue Code with the 401(k) plan’s related trust intended to be tax exempt under Section 501(a) of the Internal Revenue Code. As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.

We contribute to the Australian superannuation scheme that provides eligible Australian employees (including Ms. Boston) with an opportunity to save for retirement on a tax-advantaged basis. We pay superannuation in accordance with legislative requirements and our minimum contribution is set by legislation. We offer flexibility for salary sacrifice to be added to the superannuation scheme and any actual increase in our contribution to the superannuation scheme is subject to legislative rules at the time.

Termination or Change in Control Benefits

The employment agreements with our NEOs provide for specified notice periods (or pay in lieu of notice) if the Company terminates the employment of our NEOs under certain circumstances, as described above in the “Employment Agreements with our NEOs” section. Upon the consummation of a Change in Control (as defined in the 2020 Plan), all unvested stock options granted pursuant to the 2020 Plan will immediately vest as of immediately prior to the Change in Control. Our NEOs are not eligible to receive any additional payments or benefits in connection with their termination of employment or in connection with the Company’s change in control.

Hedging and Pledging Policy

Employees (including officers) and directors of the Company are prohibited from entering into hedging transactions with respect to the Company’s securities, or engaging in transactions with respect to the Company’s securities that are of a speculative nature, including, but not limited to, put or call options, margining Company securities, or otherwise pledging Company securities as collateral.

Pay Versus Performance Disclosure

As required by Item 402(v) of Regulation S-K, which was mandated by Section 953(a) of the Dodd-Frank Act, we are providing the following information about the relationship between “compensation actually paid” to our principal executive officer (“PEO”) and average “compensation actually paid” (“CAP”) to each of our NEOs and the financial performance of the Company for the Company’s fiscal years ended June 30, 2023 (“Fiscal 2023”) and June 30, 2022 (“Fiscal 2022”), in each case calculated in a manner consistent with SEC rules.

(2) CAP to our PEO and Non-PEO NEO (Megan Boston, our Executive Director) is calculated based on the “Total Compensation” reported in the Summary Compensation Table (“SCT”) for each of the applicable fiscal years, adjusted to exclude and include certain items in accordance with Item 402(v) of Regulation S-K as follows.

(i) Represents the grant date fair value of equity-based awards granted each year as reported in the Summary Compensation Table for the applicable fiscal year. The fair values of equity compensation, including such amounts described in the tables above, are calculated in accordance with FASB ASC Topic 718. All assumptions made in the valuations are contained and described in footnote 9 to the Company’s financial statements for the nine month period ended March 31, 2023 contained in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023, filed with the SEC on May 15, 2023 or as will be further described in the Company’s Annual Report on Form 10-K for Fiscal 2023 to be filed with the SEC.

We did not report a change in pension value for any of the years reflected in this table because the Company does not maintain a defined benefit or actuarial pension plan and therefore a deduction from SCT related to such pension plans is not needed.

(ii) Reflects the value of equity calculated in accordance with the SEC methodology for determining CAP for each year shown. The fair values of equity compensation, including such amounts described in the tables below, are calculated in accordance with FASB ASC Topic 718. The amounts shown in the table reflect the total fair value on the applicable date(s) listed in the table above, and do not necessarily reflect the actual value, if any, that may be realized by the PEO.

(3) The non-PEO NEO reflected in these columns, and our only non-PEO for the covered fiscal years, is Megan Boston (Executive Director)

(4) Represents cumulative total return to holders of our common stock from June 30, 2021 (the last trading day before Fiscal 2022) through June 30, 2023 (the last trading day of the covered period), calculated from the market close on the last trading day before Fiscal 2022 through and including the end of each applicable fiscal year in the table above for which the total shareholder return is being calculated. The total shareholder return for each investment assumes that $100 was invested in our common stock and the respective index on June 30, 2021 through June 30, 2023, including reinvestment of any dividends (of which none were paid during this period).

(5) As the Company’s net income for Fiscal 2023 was not available at the time of the filing of this Form S-1, the amount shown is based on the net income (loss) for the nine month period ended March 31, 2023 as reported in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023, filed with the SEC on May 15, 2023.

45

Relationship Between Financial Performance Measures and CAP

In Fiscal 2023, there was an inverse relationship between our total shareholder return compared to our PEO CAP and our average non-PEO NEO CAP, and there was a direct relationship between our net income compared to our PEO CAP and our average non-PEO NEO CAP. Our total shareholder return decreased by approximately 11% as compared to Fiscal 2022. Our net income between Fiscal 2022 and Fiscal 2023 increased by approximately 18%. Our PEO CAP increased by approximately 343% and our average non-PEO NEO CAP increased by approximately 721%, in each case as compared to Fiscal 2022. As the Company’s net income for Fiscal 2023 was not available at the time of the filing of this Form S-1, for purposes of the Pay versus Performance Table and for purposes of describing the relationship between net income and CAP, the Company used the Company’s net income (loss) for the nine month period ended March 31, 2023 as reported in our Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2023, filed with the SEC on May 15, 2023.

In Fiscal 2022, there was a direct relationship between our total shareholder return and net income, compared to our PEO CAP and average non-PEO NEO CAP, all of which were negative in Fiscal 2022. Our total shareholder return decreased by approximately 42% as compared to Fiscal 2021. Our net income between Fiscal 2021 and Fiscal 2022 decreased by approximately 31%. And our PEO CAP and average non-PEO NEO CAP each decreased by approximately 110% and 104%, respectively, as compared to Fiscal 2021.

General

Our authorized capital stock consists of 160,000,000 shares of our common stock, par value $0.0001 per share. As of July 26, 2023, there were 1,645,951 shares of common stock outstanding (subject to adjustment based on the rounding up of fractional shares resulting from the Reverse Stock Split).

Common Stock

Dividend Rights. Subject to preferences that may be applicable to any then outstanding preferred stock, holders of the Company’s common stock are entitled to receive dividends, if any, as may be declared from time to time by the Company’s Board out of legally available funds. Dividends may be paid in cash, in property or in shares of common stock, subject to the provisions of the Certificate of Incorporation and applicable law. Declaration and payment of any dividend will be subject to the discretion of the Board. The time and amount of dividends will be dependent upon the Company’s financial condition, operations, cash requirements and availability, debt repayment obligations, capital expenditure needs, restrictions in the Company’s debt instruments, industry trends, the provisions of Delaware law affecting the payment of distributions to stockholders and any other factors the Board may consider relevant.

Voting Rights. Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. The Company’s stockholders do not have cumulative voting rights in the election of directors.

Liquidation Rights. In the event of the Company’s liquidation, dissolution or winding up, holders of the Company’s common stock are entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of the Company’s debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

Rights and Preferences. Holders of the Company’s common stock have no pre-emptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to the Company’s common stock. The rights, preferences and privileges of the holders of the Company’s common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that the Company may designate in the future.

Fully Paid and Nonassessable. All outstanding shares of the Company’s common stock are fully paid and non-assessable.

Annual Stockholder Meetings. The Certificate of Incorporation and Bylaws provide that annual stockholder meetings will be held at a date, place (if any) and time, as exclusively selected by the Board. To the extent permitted under applicable law, the Company may but is not obligated to conduct meetings by remote communications, including by webcast.

52

Reverse Stock Split. On December 7, 2022, we received the approval of the requisite number of holders of the shares of our common stock to amend our certificate of incorporation to effect a reverse split of the shares of our common stock in the range of 1-for-5 to 1-for-20, with the exact ratio to be set within such range in the discretion of our board of directors without further approval or authorization of our stockholders (the “Reverse Stock Split”). On July 26, 2023, in connection with this offering, we effected the Reverse Stock Split of our shares of common stock at a ratio of 1-for-17. No fractional shares of common stock were issued in connection with the Reverse Stock Split, and in lieu of any fractional shares to which a stockholder of record would otherwise be entitled as a result of the Reverse Stock Split, we rounded up to the nearest whole number of shares to which a stockholder was entitled. The Reverse Stock Split required that proportionate adjustments be made to the conversion rate, the per share exercise price and the number of shares issuable upon the vesting, exercise or conversion of outstanding derivative securities issued by us.

Common Warrants to be Issued as Part of this Offering

The following summary of certain terms and provisions of the common warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of common warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of common warrant for a complete description of the terms and conditions of the common warrants.

We are selling to investors in this offering 417,815 shares of our common stock and 15,126,226 pre-funded warrants each with accompanying common warrants to purchase 15,544,041 shares of our common stock at a combined purchase price of $1.93 for shares and accompanying common warrants and $1.9299 for pre-funded warrants and accompanying common warrants.

Exercise Price and Duration. Each common warrant will be exercisable beginning on the date of closing of this offering, at an exercise price of $3.86 per share, subject to adjustment. The common warrants will be exercisable for five years from such date, but not thereafter. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

Exercisability. Subject to limited exceptions, a holder of common warrants will not have the right to exercise any portion of its common warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, 9.99%) of the number of shares of our common stock outstanding immediately after giving effect to such exercise (the “Beneficial Ownership Limitation”); provided, however, that upon 61 days’ prior notice to the Company, the holder may increase or decrease the Beneficial Ownership Limitation, provided that in no event shall the Beneficial Ownership Limitation exceed 9.99%.

Cashless Exercise. The common warrants contain a “cashless exercise” feature that allows holders to exercise the common warrants without a cash payment to the Company upon the terms set forth in the common warrants, if, at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for, the issuance of the shares to the exercising common warrant holder.

Exercise Limitation. A holder (together with its affiliates) may not exercise any portion of a common warrant to the extent that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of the outstanding common shares immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding stock after exercising the holder’s common warrants up to 9.99% of the number of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the common warrants. Purchasers of common warrants in this offering may also elect prior to the issuance of the common warrants to have the initial exercise limitation set at 9.99% of our outstanding common shares.

53

Transferability. Subject to applicable laws, a common warrant may be transferred at the option of the holder upon surrender of the common warrant to us together with the appropriate instruments of transfer.

Fractional Shares. No fractional common shares will be issued upon the exercise of the common warrants. Rather, the number of common shares to be issued will be rounded down to the nearest whole number.

Trading Market. There is no established public trading market for the common warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the common warrants on any national securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the common warrants will be limited.

Right as a Stockholder. Except as otherwise provided in the common warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the common warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their common warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the common warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the common warrants will be entitled to receive upon exercise of the common warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the common warrants immediately prior to such fundamental transaction.

Amendment and Waiver. A common warrant may be modified or amended or the provisions thereof waived with the written consent of our company and the holder of the common warrant.

Pre-Funded Warrants to be Issued as Part of this Offering

The following summary of certain terms and provisions of the pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.

Exercise Price and Duration. Each pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.0001 and will be exercisable for 15,126,226 shares of our common stock. The pre-funded warrants will be immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

Exercisability. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). Purchasers of the pre-funded warrants in this offering may elect to deliver their exercise notice following the pricing of the offering and prior to the issuance of the pre-funded warrants at closing to have their pre-funded warrants exercised immediately upon issuance and receive shares of common stock underlying the pre-funded warrants upon closing of this offering. A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of the outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after

54

exercising the holder’s pre-funded warrants. No fractional shares of common stock will be issued in connection with the exercise of a pre-funded warrant. In lieu of fractional shares, we will round down to the next whole share.

Cashless Exercise. If, at the time a holder exercises its pre-funded warrants, a registration statement registering the issuance of the shares of common stock underlying the pre-funded warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.

Exercise Limitation. A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% (or, at the election of the holder, 9.99%) of the outstanding common shares immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding stock after exercising the holder’s pre-funded warrants up to 9.99% of the number of our common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding common shares.

Transferability. Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the warrant to us together with the appropriate instruments of transfer.

Fractional Shares. No fractional common shares will be issued upon the exercise of the pre-funded warrants. Rather, the number of common shares to be issued will be rounded down to the nearest whole number.

Trading Market. There is no established public trading market for the pre-funded warrants, and we do not expect a market to develop. In addition, we do not intend to apply to list the pre-funded warrants on any national securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the pre-funded warrants will be limited.

Right as a Stockholder. Except as otherwise provided in the pre-funded warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the pre-funded warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their pre-funded warrants.

Fundamental Transaction. In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding common stock, or any person or group becoming the beneficial owner of 50% of the voting power represented by our outstanding common stock, the holders of the pre-funded warrants will be entitled to receive upon exercise of the pre-funded warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the pre-funded warrants immediately prior to such fundamental transaction.

Amendment and Waiver. A pre-funded warrant may be modified or amended or the provisions thereof waived with the written consent of our company and the holder of the pre-funded warrant.

Existing Pre-Funded Warrants

On September 15, 2022, the Company issued certain pre-funded warrants pursuant to a registration statement which became effective on September 14, 2022 (Registration No. 333-266417). These existing pre-funded warrants have the same characteristics as those pre-funded warrant offered hereby, as described above, except that the exercise price per share of such existing pre-funded warrants is now equal to $0.0017 after giving effect to the Reverse Stock Split. As of July 26, 2023, 12,171,628 existing pre-funded warrants had been issued. Prior to the Reverse Stock Split, 2,171,628 had been exercised with a weighted average exercise price of $0.0001 per share. After the Reverse Stock Split, 10,000,000 existing pre-funded warrants remain outstanding with an average exercise price of $0.0017 per share and such existing pre-funded warrants are exercisable for a total of 588,236 shares of common stock.

Existing Warrants

On September 15, 2022, the Company issued certain common warrants pursuant to a registration statement which became effective on September 14, 2022 (Registration No. 333-266417). As of July 26, 2023, 29,809,471 of the existing common warrants had been issued with a weighted average exercise price of $11.22 per share (after giving effect to the Reverse Stock Split) and no existing common warrants had been exercised. These warrants also contain an exercise price adjustment mechanism providing that certain issuances of common stock (or common stock equivalents), including issuances as a result of this offering, if made at a price lower than the existing exercise price of $11.22, would reset the exercise price to such lower price.

In September of 2019, Benitec Limited issued warrants for the purchase of its ADSs. In connection with the Re-domiciliation, these warrants became obligations of the Company. Currently, there are warrants outstanding for the exercise of 6,300 shares of the Company’s common stock at an exercise price of $178.50 per share (after giving effect to the Reverse Stock Split). The exercise price is subject to appropriate adjustment in the event of certain share dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our shares of common stock and also upon any distributions of assets, including cash, stock or other property to our stockholders. The warrants are exercisable, at the option of each holder, in whole or in part by delivering to us a duly executed exercise notice and, at any time a registration statement registering the issuance of the shares underlying the warrants under the Securities Act is effective and available for the issuance of such shares (or there is an effective registration statement for the resale of such shares), by payment in full in immediately available funds for the number of shares purchased upon such exercise. If no such registration statement is currently effective at the time of an exercise, the warrants will be exercisable on a cashless basis. No fractional shares will be issued in connection with the exercise of a warrant. In lieu of fractional shares, we will round up to the next whole share or pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price.

Subject to limited exceptions, holders of these warrants do not have the right to exercise any portion of their warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% of the shares of common stock then outstanding after giving effect to such exercise (the “Warrant Beneficial Ownership Limitation”); provided, however, that, upon notice to the Company, the holder may increase or decrease the Warrant Beneficial Ownership Limitation, provided that in no event shall the Warrant Beneficial Ownership Limitation exceed 9.99% and any increase in the Warrant Beneficial Ownership Limitation will not be effective until 61 days following notice of such increase from the holder to us.

Except as otherwise provided in the warrants or by virtue of such holder’s ownership of shares of common stock, a holder of these warrants does not have the rights or privileges of a holder of our common stock, including any voting rights, until the holder exercises the warrant. The foregoing summary of the material terms and provisions of these warrants is qualified in its entirety by the form of warrant, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part.

Anti-Takeover Effects of Provisions of the Certificate of Incorporation and Bylaws and DGCL

Some provisions of the DGCL, the Certificate of Incorporation and Bylaws could make the following transactions difficult: (i) acquisition of the Company by means of a tender offer; (ii) acquisition of the Company by means of a proxy contest or otherwise; or (iii) removal of incumbent officers and directors of the Company. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in the best interests of the Company, including transactions that might result in a premium over the market price for the Company’s common stock.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of the Company to first negotiate with the Board.

Delaware Anti-Takeover Statute. The Company is subject to Section 203 of the DGCL, which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a publicly-held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock, and a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the Board, such as discouraging takeover attempts that might result in a premium over the market price of the Company’s common stock.

Special Stockholder Meetings. The Bylaws provide that a special meeting of stockholders may be called by (i) the Chairman of the Board, if any, (ii) the President or Chief Executive Officer, or (iii) the Board pursuant to a resolution adopted by a majority of the total number of directors then in office.

Requirements for Advance Notification of Stockholder Nominations and Proposals. The Bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors.

Composition of the Board of Directors; Election and Removal of Directors; Filling Vacancies

The Company’s Board consists of five directors and the Board may, from time to time, fix the authorized number of directors by resolution of the Board. The Board is divided into three classes, designated Class I, Class II and Class III. Directors need not be stockholders of the Company.

Directors shall serve for a term ending on the date of the third annual meeting of stockholders following the annual meeting of stockholders at which such director was elected. The term of each director shall continue until the election and qualification of his or her successor and be subject to his or her earlier death, disqualification, resignation or removal. Except as otherwise provided by the DGCL, the Certificate of Incorporation or the Bylaws, directors shall be elected by a plurality of the votes of the shares present in person, by remote communication, if applicable, or represented by a duly authorized and executed proxy at the meeting and entitled to vote on the election of directors.

Subject to applicable law or by the Certificate of Incorporation, any director of the entire Board of the Company may be removed without cause by the affirmative vote of a majority of the holders of the Company’s then-outstanding common stock entitled to vote generally at an election of directors. Furthermore, any vacancy on the Company’s Board, however occurring, including a vacancy resulting from an increase in the size of the board, may be filled only by a majority vote of the Board then in office, even if less than a quorum, or by the sole remaining director.

57

Amendment of the Certificate of Incorporation and Bylaws. The Certificate of Incorporation may be amended in any manner permitted under the DGCL and the Bylaws may be amended by the vote or written consent of holders of a majority of the outstanding shares entitled to vote. The Board may also amend the Bylaws, other than a bylaw or amendment thereof specifying or changing a fixed number of directors or the maximum or minimum number or changing from a fixed to a variable board or vice versa.

Limitations of Liability and Indemnification Matters

Each of the Certificate of Incorporation and Bylaws provide that the Company is required to indemnify its directors and officers to the fullest extent not prohibited by Delaware law. The Bylaws also obligate the Company to advance expenses incurred by a director or officer in advance of the final disposition of any action or proceeding upon delivery to the Company of an undertaking, by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision, from which there is no further right to appeal, that such indemnitee is not entitled to be indemnified for such expenses.

To the fullest extent permitted by the DGCL, or any other applicable law, the Company, upon approval by the Board, may purchase insurance on behalf of any person required or permitted to be indemnified pursuant to the Bylaws.

Forum for Adjudication of Disputes

The Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the sole and exclusive forum for (i) derivative actions or proceedings brought on behalf of the Company, (ii) any action asserting a claim of breach of fiduciary duty owed by any director, officer or employee of the Company to the Company or the Company’s stockholders, (iii) an action asserting a claim arising pursuant to any provision of the DGCL, or (iv) any action asserting a claim governed by the internal affairs doctrine shall be a state or federal court located within the state of Delaware. The Certificate of Incorporation further provides that the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the exclusive forum for any complaint asserting a cause of action arising under the Securities Act.

Transfer Agent and Registrar and Warrant Agent

The transfer agent and registrar and warrant agent for the Company’s common stock and warrants is Computershare Trust Company, N.A. The transfer agent and registrar’s and warrant agent’s address is 250 Royall St., Canton, Massachusetts 02021.

Listing

Our common stock is listed on Nasdaq under the symbol “BNTC.”

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS FOR HOLDERS OF OUR COMMON STOCK, COMMON WARRANTS AND PRE-FUNDED WARRANTS

The following discussion is a summary of the material U.S. federal income tax considerations to U.S. Holders and Non-U.S. Holders (each as defined below and, together “Holders”) of the purchase, ownership and disposition of our common stock, common warrants and pre-funded warrants that are issued pursuant to this offering. This does not purport to be a complete analysis of all potential tax effects to Holders of purchasing, owning or disposing of our common stock, common warrants or pre-funded warrants. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws are not included in this discussion, and Holders should consult their own tax advisors as to these matters. This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), final, temporary and proposed Treasury Regulations promulgated thereunder, judicial decisions and administrative pronouncements of the Internal Revenue Service (the “IRS”), in effect as of the date of this offering. These authorities may change or be subject to differing interpretations. Any such change may be applied retroactively in a manner that could adversely affect a Holder. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance that the IRS will not take or that a court will not uphold a contrary position regarding the tax consequences of the purchase, ownership and disposition of our common stock, common warrants and pre-funded warrants.

This discussion is limited to Holders that hold our common stock, common warrants and pre-funded warrants as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Holder’s particular circumstances. In addition, it does not address consequences relevant to Holders subject to special rules, including, without limitation:

• banks, insurance companies and other financial institutions;

• real estate investment trusts, regulated investment companies, and other entities treated as conduits for U.S. federal income tax purposes;

• brokers, dealers or traders in securities;

• Holders who are subject to the mark-to-market accounting rules under Section 475 of the Code;

• “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax;

• partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes;

• tax-exempt organizations and governmental organizations or agencies;

• Holders who hold or receive our common stock, common warrants or pre-funded warrants pursuant to the exercise of any employee stock option or otherwise as compensation;

• tax-qualified retirement plans;

• “qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds;

• U.S. expatriates and certain former citizens or long-term residents of the United States;

• U.S. Holders whose functional currency is not the United States dollar;

• Holders deemed to sell our common stock, common warrants or pre-funded warrants under the constructive sale provisions of the Code;

• Holders for whom our common stock, common warrants and pre-funded warrants constitute “qualified small business stock” within the meaning of Section 1202 of the Code;

59

• Holders subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an “applicable financial statement” (as defined in the Code);

• Holders who hold our common stock, common warrants or pre-funded warrants as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment; and

• Holders subject to the alternative minimum tax.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds our common stock, common warrants or pre-funded warrants, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our common stock, common warrants or pre-funded warrants and the partners in such partnerships should consult their own tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT INTENDED AS TAX ADVICE. INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, COMMON WARRANTS OR PRE-FUNDED WARRANTS ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Although the characterization of the pre-funded warrants for U.S. federal income tax purposes is not entirely clear, because the exercise price of the pre-funded warrants is a nominal amount, the Company expects to treat the pre-funded warrants as common stock of the Company for U.S. federal income tax purposes. Except where noted, the remainder of this discussion assumes that the pre-funded warrants will be so treated. Each Holder should consult its own tax advisor regarding the proper characterization of the pre-funded warrants for U.S. federal, state and local, and non-U.S. tax purposes, and the consequences to them of such treatment given their individual circumstances. Some portions of the below discussion make reference to potential consequences associated with the purchase, ownership and disposition of the pre-funded warrants independent of their potential characterization as common shares.

Allocation of Purchase Price

Each purchaser of shares of our common stock or pre-funded warrants must allocate its purchase price for such shares or pre-funded warrants between each share or pre-funded warrant, as applicable, and the accompanying common warrant based on the respective relative fair market values of each at the time of issuance. This allocation of the purchase price will establish the Holder’s initial tax basis for U.S. federal income tax purposes for each share of our common stock, pre-funded warrant and common warrant. A Holder’s allocation of the purchase price among the shares of our common stock, pre-funded warrants and common warrants is not binding on the IRS or the courts, and no assurance can be given that the IRS or the courts will agree with a Holder’s allocation. Each Holder should consult its tax advisor regarding the allocation of the purchase price among the shares of our common stock, pre-funded warrants and common warrants.

U.S. Holders

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of our common stock or pre-funded warrants that is, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

60

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust that (i) is subject to the primary supervision of a U.S. court and the control of one or more U.S. persons (within the meaning of Section 7701(a)(30) of the Code), or (ii) has made a valid election under applicable Treasury Regulations to continue to be treated as a U.S. person.

If you are not a U.S. Holder, this section does not apply to you. Please see the discussion under “Non-U.S. Holders” below.

Distributions on Common Stock

As described in the section captioned “Dividend Policy,” we do not anticipate declaring or paying distributions to Holders of our common stock in the foreseeable future. However, distributions (including constructive distributions as described below), if any, on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles.

Distributions in excess of current and accumulated earnings and profits will constitute a return of capital that will be applied against and reduce (but not below zero) the U.S. Holder’s adjusted tax basis in our common stock. Any remaining excess will be treated as gain realized on the sale or other disposition of the common stock and will be treated as described under “U.S. Holders—Sale or Other Taxable Disposition of Common Stock, Common Warrants or Pre-funded Warrants” below.

Dividends we pay to a U.S. Holder that is a taxable corporation generally will qualify for the dividends received deduction if the requisite holding period is satisfied. With certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), and provided the common shares are held for more than 60 days during the 121-day period beginning 60 days before the ex- dividend date and certain other holding period requirements are met, dividends we pay to a non-corporate U.S. Holder generally will constitute “qualified dividends” that will be subject to tax at the maximum tax rate accorded to long-term capital gains. Dividends paid by us will generally be treated as income from U.S. sources. U.S. Holders should consult their own tax advisors regarding the holding period and other requirements that must be satisfied in order to qualify for the reduced maximum tax rate on dividends.

Sale or Other Taxable Disposition of Common Stock, Common Warrants or Pre-funded Warrants

Upon a sale, exchange or other taxable disposition of common stock, common warrants or pre-funded warrants, a U.S. Holder generally will recognize capital gain or loss in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the common stock, common warrant or pre-funded warrant, as the case may be. A U.S. Holder’s adjusted tax basis in the common stock generally will equal the U.S. Holder’s acquisition cost of such security less, in the case of common stock (and potentially a pre-funded warrant and/or a common warrant) and as described further above, the amount of any prior distributions treated as a return of capital on such stock. If a U.S. Holder purchases or sells common stock, common warrants and/or pre-funded warrants together in a single transaction in which the purchase price for each of the common stock, common warrants and/or pre-funded warrants was not separately stated, the U.S. Holder generally would be required to allocate the purchase price among the subject securities so acquired or disposed of, as applicable, based on the relative fair market values of each (at the time of the acquisition or disposition, as applicable). U.S. Holders who purchase or sell common stock, common warrants and/or pre-funded warrants in a single transaction should consult with their tax advisors regarding such allocation.

Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for the common stock, common warrants or pre-funded warrants disposed of exceeds one year. Long-term

61

capital gains recognized by non-corporate U.S. Holders will be eligible to be taxed at reduced rates. The deductibility of capital losses is subject to limitations.

Exercise of a Common Warrant or a Pre-funded Warrant

A U.S. Holder generally will not recognize taxable gain or loss on the acquisition of common stock upon exercise of a common warrant or pre-funded warrant. The U.S. Holder’s aggregate tax basis in the share of our common stock received upon exercise of a common warrant or pre-funded warrant generally will be an amount equal to the sum of the U.S. Holder’s tax basis in the common warrant or pre-funded warrant prior to exercise and the common warrant’s or pre-funded warrant’s exercise price. Provided that a pre-funded warrant is treated as our common stock, a U.S. Holder’s holding period for the common stock received upon exercise of a pre-funded warrant will include the holding period for the pre-funded warrant. On the other hand, in the case of a common warrant, and also if the pre-funded warrant is treated as an option to purchase our stock, a U.S. Holder’s holding period for the common stock received upon exercise will begin on the date following the date of exercise of the common warrant (or the pre-funded warrant, as applicable) and will not include the period during which the U.S. Holder held the common warrant (or the pre-funded warrant, as applicable).

A U.S. Holder may be permitted to undertake a cashless exercise of common warrants or pre-funded warrants into our common stock. The U.S. federal income tax treatment of a cashless exercise is unclear, and the tax consequences of a cashless exercise could differ from the consequences of an exercise described above. For example, the cashless exercise could be treated as a taxable disposition of a portion of the common warrants, pre-funded warrants or the common shares into which they are exercisable. U.S. Holders should consult their own tax advisors regarding the U.S. federal income tax consequences of a cashless exercise.

Lapse of Common Warrants

Upon the lapse or expiration of a common warrant, a U.S. Holder will recognize a loss in an amount equal to such U.S. holder’s tax basis in the common warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the common warrant is held for more than one year. The deductibility of capital losses is subject to limitations.

Certain Adjustments to the Common Warrants and Pre-funded Warrants and Payments in Respect of the Common Warrants and Pre-funded Warrants

Under Section 305 of the Code, an adjustment to the number of shares of common stock that will be issued on the exercise of the common warrants or pre-funded warrants, or an adjustment to the exercise price of the common warrants or pre-funded warrants, may be treated as a constructive distribution to a U.S. Holder of the common warrants or pre-funded warrants if, and to the extent that, such adjustment has the effect of increasing such U.S. Holder’s proportionate interest in our “earnings and profits” or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to our shareholders). Adjustments to the exercise price of common warrants or pre-funded warrants made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the U.S. Holder of the common warrants or pre-funded warrants generally should not be considered to result in a constructive distribution. Any constructive distribution would be treated as a dividend, return of capital or capital gain as described under the heading “U.S. Holder—Distributions on Common Stock” above, and could be taxable whether or not there is an actual distribution of cash or other property. U.S. Holders should consult their tax advisors regarding the proper treatment of any adjustments to and payments in respect of common warrants or pre-funded warrants.

Net investment income tax

An additional 3.8% tax is imposed on the “net investment income” of non-corporate U.S. Holders, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment

62

income” generally includes dividends paid on our common stock and certain net gain from the sale or other taxable disposition of our common stock, common warrants and pre-funded warrants, less certain deductions. U.S. Holders should consult their own tax advisors concerning the potential effect, if any, of this tax on holding our common stock, common warrants and pre-funded warrants in such U.S. Holder’s particular circumstances.

Backup withholding and information reporting

For non-corporate U.S. Holders, information reporting requirements, on IRS Form 1099, generally will apply to:

• dividend payments or other taxable distributions on our common stock, common warrants and pre-funded warrants made to the non-corporate U.S. Holder within the United States or by a U.S. payor; and

• the payment of proceeds to the non-corporate U.S. Holder from the sale of a share of common stock, common warrants or pre-funded warrants effected at a U.S. office of a broker or through certain U.S.-related financial intermediaries.

Additionally, backup withholding may apply to such payments if the non-corporate U.S. Holder:

• fails to provide an accurate taxpayer identification number;

• is notified by the IRS that it has failed to report all interest and dividends required to be shown on its U.S. federal income tax returns; or

• in certain circumstances, fails to comply with applicable certification requirements.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-corporate U.S. Holder’s U.S. federal income tax liability (if any), provided the required information is timely furnished to the IRS. U.S. Holders are urged to consult their own tax advisors regarding the application of backup withholding and the availability of and procedure for obtaining an exemption from backup withholding in their particular circumstances.

Non-U.S. Holders

For purposes of this discussion, a Non-U.S. Holder is a beneficial owner of our common stock, common warrants or pre-funded warrants that, for U.S. federal income tax purposes, is neither a U.S. Holder (as defined above) nor a partnership or other pass-through entity. If you are not a Non-U.S. Holder, this section does not apply to you.

Distributions on Common Stock

As described in the section captioned “Dividend Policy,” we do not anticipate declaring or paying distributions to Holders of our common stock in the foreseeable future. However, distributions, if any, on our common stock in cash will generally constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “Non-U.S. Holders—Sale or Other Taxable Disposition of Common Stock, Common Warrants or Pre-Funded Warrants.”

Subject to the discussion below regarding backup withholding and payments made to certain foreign accounts, dividends paid to a Non-U.S. Holder of our common stock (including constructive distributions treated as a dividend) that are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate as may be specified by an applicable income tax treaty).

63

Non-U.S. Holders may be entitled to a reduction in or an exemption from withholding on dividends as a result of either (i) qualifying for the benefits of an applicable income tax treaty or (ii) the Non-U.S. Holder holding our common stock in connection with the conduct of a trade or business within the United States and dividends being paid in connection with that trade or business. To claim such a reduction in or exemption from withholding, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed (i) IRS Form W-8BEN or W-8BEN-E (or applicable successor form) claiming a reduction in or an exemption from the withholding tax under the benefits of an applicable income tax treaty, (ii) IRS Form W-8ECI (or applicable successor form) stating that the dividends are effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States, or (iii) a suitable substitute form, as may be applicable. These certifications must be provided to the applicable withholding agent prior to the payment of dividends and must be updated periodically. Non-U.S. Holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Subject to the discussion below regarding backup withholding and payments made to certain foreign accounts, if dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (or, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), then, although generally exempt from U.S. federal withholding tax (provided the Non-U.S. Holder provides appropriate certification, as described above), the Non-U.S. Holder will be subject to U.S. federal income tax on such dividends on a net-income basis at the regular graduated U.S. federal income tax rates. In addition, a Non-U.S. Holder that is (or is treated as) a corporation for U.S. federal income tax purposes may be subject to an additional branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits for the taxable year that are attributable to such dividends, as adjusted for certain items. Non-U.S. Holders should consult their own tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Sale or Other Taxable Disposition of Common Stock, Common Warrants or Pre-funded Warrants

Subject to the discussion below regarding backup withholding and payments made to certain foreign accounts, a Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain recognized upon the sale or other taxable disposition of our common stock, common warrants or pre-funded warrants unless:

• the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (or, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

• the Non-U.S. Holder is a non-resident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

• we are or have been a “United States real property holding corporation,” or USRPHC, for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the period that the Non-U.S. Holder held the common stock, common warrants or pre-funded warrants.

Gain described in the first bullet point above will generally be subject to U.S. federal income tax on a net-income basis at the regular graduated U.S. federal income tax rates. A Non-U.S. Holder that is a non-U.S. corporation also may be subject to an additional branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on a portion of its effectively connected earnings and profits for the taxable year, as adjusted for certain items.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on any gain derived from

64

the sale or other taxable disposition, which may be offset by certain U.S.-source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States) provided the Non-U.S. Holder timely files U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe that we are not, and do not anticipate that we will become, a USRPHC.

The method of determining the amount of gain by a Non-U.S. Holder on disposition of the common stock, common warrants or pre-funded warrants generally will correspond to the method of determining the amount of gain (or loss) by a U.S. Holder on disposition of the common stock, common warrants or pre-funded warrants, as described under “U.S. Holders—Sale or Other Taxable Disposition of Common Stock, Common Warrants or Pre-funded Warrants” above. Non-U.S. Holders should consult their own tax advisors regarding potentially applicable income tax treaties that may provide for different rules, and the potential application of other exceptions to these taxes.

Exercise of a Common Warrant or Pre-funded Warrant

For certain Non-U.S. Holders engaged in the conduct of a trade or business within the United States, the U.S. federal income tax treatment of the exercise of a common warrant or pre-funded warrant, generally will correspond to the U.S. federal income tax treatment of the exercise of a common warrant or pre-funded warrant by a U.S. Holder, as described under “U.S. Holders—Exercise of a Common Warrant or Pre-funded Warrant” above. For all other Non-U.S. holders, the exercise of a common warrant or pre-funded warrant generally will not be a taxable event for U.S. federal income tax purposes.

Lapse of a Common Warrant

Upon the lapse or expiration of a common warrant, a Non-U.S. Holder will recognize a loss in an amount equal to such Non-U.S. Holder’s tax basis in the common warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the common warrant is held for more than one year. The deductibility of capital losses is subject to limitations.

Certain Adjustments to the Common Warrants and Pre-funded Warrants and Payments in Respect of the Common Warrants and Pre-funded Warrants

Under Section 305 of the Code, an adjustment to the number of shares of common stock that will be issued on the exercise of the common warrants or pre-funded warrants, or an adjustment to the exercise price of the common warrants or pre-funded warrants, may be treated as a constructive distribution to a Non-U.S. Holder of the common warrants or pre-funded warrants if, and to the extent that, such adjustment has the effect of increasing such Non-U.S. Holder’s proportionate interest in our “earnings and profits” or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to our shareholders). Adjustments to the exercise price of common warrants or pre-funded warrants made pursuant to a bona fide reasonable adjustment formula that has the effect of preventing dilution of the interest of the Non-U.S. Holder of the common warrants or pre-funded warrants generally should not be considered to result in a constructive distribution. Any constructive distribution would be treated as a dividend, return of capital or capital gain as described under the heading “Non-U.S. Holders—Distributions on Common Stock” above, and could be taxable whether or not there is an actual distribution of cash or other property.

In addition, regulations governing “dividend equivalents” under Section 871(m) of the Code may apply to the common warrants or pre-funded warrants. Under those regulations, an implicit or explicit payment under the common warrants or pre-funded warrants that references a dividend distribution on our common stock (including an adjustment to the amount due on the common warrants or pre-funded warrant to take into account a dividend distribution on our common stock) would be taxable to a Non-U.S. Holder as described under the heading

65

“Non-U.S. Holders—Distributions on Common Stock” above. Such dividend equivalent amount would be taxable and subject to withholding whether or not there is actual payment of cash or other property, and the Company may satisfy any withholding obligations it has in respect of the common warrants or pre-funded warrants by withholding from other amounts due to the Holder. Non-U.S. Holders are encouraged to consult their own tax advisors regarding the application of Section 871(m) of the Code to the common warrants or pre-funded warrants.

Information Reporting and Backup Withholding

Subject to the discussion below regarding payments made to certain foreign accounts, a Non-U.S. Holder generally will not be subject to backup withholding with respect to payments of dividends on our common stock we make to the Non-U.S. Holder, provided the applicable withholding agent does not have actual knowledge or reason to know such Holder is a U.S. person and the Holder certifies its non-U.S. status by providing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or other applicable certification (or applicable successor form), or otherwise establishes an exception. However, information returns will be filed with the IRS in connection with any dividends or other distributions on our common stock paid to the Non-U.S. Holder (including constructive distributions), regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Information reporting and backup withholding may apply to the proceeds of a sale of a share of our common stock, common warrants or pre-funded warrants within the United States, and information reporting may (although backup withholding will generally not) apply to the proceeds from the sale of a share of our common stock, common warrants or pre-funded warrants outside the United States conducted through certain U.S.-related financial intermediaries, in each case, unless the beneficial owner certifies under penalty of perjury that it is a Non-U.S. person on IRS Form W-8BEN or other applicable form or successor form (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person) or otherwise establishes an exemption.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability (if any), provided the required information is timely furnished to the IRS. Non-U.S. Holders are urged to consult their own tax advisors regarding the application of backup withholding and the availability of and procedure for obtaining an exemption from backup withholding in their particular circumstances.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under the provisions of the law generally known as the Foreign Account Tax Compliance Act, or FATCA, on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends (including constructive dividends) paid on our common stock, common warrants or pre-funded warrants, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of our common stock, common warrants or pre-funded warrants paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (i) the foreign financial institution undertakes certain diligence and reporting obligations, (ii) the non-financial foreign entity either certifies it does not have any “substantial U.S. owners” (as defined in the Code) or furnishes identifying information regarding each substantial U.S. owner, or (iii) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (i) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified U.S. persons” or “U.S.-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts and withhold 30% on payments to non-compliant foreign financial institutions and certain other account

66

holders. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury Regulations or other guidance, may modify these requirements.

Under the applicable Treasury Regulations and guidance from the IRS, withholding under FATCA generally applies to payments of dividends (including constructive dividends) on our common stock, common warrants or pre-funded warrants. The FATCA withholding tax will apply to all withholdable payments without regard to whether the beneficial owner of the payment would otherwise be entitled to an exemption from imposition of withholding tax pursuant to an applicable tax treaty with the United States or U.S. domestic law. We will not pay additional amounts to Holders of our common stock, common warrants or pre-funded warrants in respect of any amounts withheld. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of our common stock, common warrants or pre-funded warrants on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally are permitted to rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their own tax advisors regarding the potential application of withholding under FATCA to their investment in our common stock, common warrants and pre-funded warrants.

67

UNDERWRITING

Citizens JMP Securities, LLC is acting as underwriter. Subject to the terms and conditions set forth in an underwriting agreement among us and the underwriter, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, the number of shares of common stock set forth opposite its name below.

Underwriter	Number of Shares and Common Warrants		Number of Pre-Funded Warrants and Common Warrants
Citizens JMP Securities, LLC		417,815		15,126,226

Subject to the terms and conditions set forth in the underwriting agreement, the underwriter has agreed to purchase all of the securities sold under the underwriting agreement if any are purchased other than those shares and/or common warrants covered by the over-allotment option described below. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased.

We have agreed to indemnify the underwriter against certain liabilities including liabilities under the Securities Act, or to contribute to payments the underwriter may be required to make in respect of those liabilities.

The underwriter is offering the securities, subject to prior sale, when, as and if issued to and accepted by it, subject to approval of legal matters by its counsel, including the validity of the securities, and other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officer’s certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The underwriter has advised us that it proposes initially to offer the securities to the public at the public offering price set forth on the cover page of this prospectus and to dealers at that price less a concession not in excess of $0.081060 per share. After this public offering, the underwriter may change the public offering price and concession and discount to dealers.

The following table shows the public offering price, underwriting discount and proceeds, before expenses, to us.

	Per Share and Common Warrant		Per Pre-Funded Warrant and Common Warrant		Total
Public offering price	$	1.93	$	1.9299	$	29,998,486.51
Underwriting discount (7%)	$	0.1351	$	0.1351	$	2,099,894.06
Proceeds, before expenses, to us	$	1.7949	$	1.7948	$	27,898,592.45

We have agreed to pay the representative’s out-of-pocket accountable expenses, including its legal fees, up to a maximum amount of $125,000. The estimated expenses of this offering payable by us, exclusive of the underwriting discount, are approximately $310,931.

68

Over-allotment Option

We have granted an option to the underwriter to purchase up to 2,331,606 additional shares of our common stock at a price per share of $1.9299 and/or up to an additional 2,331,606 warrants to purchase up to 2,331,606 shares of common stock at a price per warrant of $0.0001, less, in each case, the underwriting discount. If available, the underwriter may exercise this option for 30 days from the date of this prospectus solely to cover any over-allotments.

Right of First Refusal

In connection with this offering, we granted to Citizens JMP Securities, LLC, for the twelve (12) month period following the commencement of sales of securities, a right of first refusal to act as sole lead manager, underwriter and/or placement agent for any and all future public or private equity, equity-linked, convertible and debt offerings (excluding commercial bank debt), with at least 50% of the economics provided to placement agents or underwriters, as applicable, during such twelve (12) month period by us, or any successor to or any subsidiary of our company subject to such procedures as agreed upon in the underwriting agreement entered into in connection with this offering.

No Sales of Similar Securities

We and each of our executive officers and directors have agreed with the underwriters not to offer, sell or otherwise dispose of any common stock or any securities convertible into or exercisable or exchangeable for or that represent the right to receive common stock or any rights to acquire common stock for a period of 90 days following the date of this prospectus, with certain limited exceptions, without first obtaining the written consent of Citizens JMP Securities, LLC, the representative of the underwriters. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly:

• offer, pledge, sell or contract to sell any common stock;

• sell any option or warrant to purchase any common stock;

• purchase any option or warrant to sell any common stock;

• grant any option or warrant for the sale of any common stock;

• lend or otherwise transfer or dispose of any common stock;

• exercise any right with respect to the registration of any common stock or other securities; or

• enter into any swap or other agreement or transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of any common stock whether any such swap, agreement or transaction is to be settled by the delivery of shares of common stock or other securities, in cash or otherwise.

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or that represent the right to receive common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Listing on Nasdaq

Our common stock is listed on Nasdaq under the symbol “BNTC”. We do not intend to apply for the listing of the common warrants or the pre-funded warrants on any national securities exchange or other nationally recognized trading system, including Nasdaq.

69

Discretionary Sales

The underwriters do not expect to sell more than 5% of the shares sold in this offering in the aggregate to accounts over which they exercise discretionary authority.

Price Stabilization, Short Positions and Penalty Bids

Until the distribution of our shares of common stock is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representative may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with this offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares of our common stock than they are required to purchase in this offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ over-allotment option described above. The underwriters may close out any covered short position by either exercising their over-allotment option or purchasing shares of our common stock in the open market. In determining the source of shares of our common stock to close out the covered short position, the underwriters will consider, among other things, the price of shares of our common stock available for purchase in the open market as compared to the price at which they may purchase shares of our common stock through the over-allotment option. “Naked” short sales are sales in excess of the over-allotment option. The underwriters must close out any naked short position by purchasing shares of our common stock in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering. Stabilizing transactions consist of various bids for or purchases of shares of our common stock made by the underwriters in the open market prior to the completion of this offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative has repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on Nasdaq, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representative will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Offer, Sale and Distribution of Shares

In connection with this offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail. In addition, the underwriters may facilitate Internet distribution for this offering to certain of their Internet subscription customers. The underwriters may allocate a limited number of securities for sale to their online brokerage customers. An electronic prospectus is available on the Internet website maintained by the underwriters. Other than the prospectus in electronic format, the information on the underwriters’ websites is not part of this prospectus.

The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Sales Outside the United States

No action has been or will be taken in any jurisdiction (except in the United States) that would permit a public offering of the common stock, or the possession, circulation or distribution of this prospectus or any other material relating to us or the common stock in any jurisdiction where action for that purpose is required. Accordingly, the common stock may not be offered or sold, directly or indirectly, and neither of this prospectus nor any other offering material or advertisements in connection with the common stock may be distributed or published, in or from any country or jurisdiction except in compliance with any applicable rules and regulations of any such country or jurisdiction.

Each of the underwriters may arrange to sell common stock offered by this prospectus in certain jurisdictions outside the United States, either directly or through affiliates, where they are permitted to do so.
