PART I

ITEM 1.BUSINESS

Overview

We are engaged in the research and development of targeted, non-systemic therapies for the treatment of patients with gastrointestinal (“GI”) diseases. Non-systemic therapies are non-absorbable drugs that act locally, i.e., in the intestinal lumen, skin or mucosa, without reaching an individual’s systemic circulation. In May 2024, we changed our name from First Wave Biopharma, Inc. to Entero Therapeutics, Inc.

We are currently focused on developing the biologic Adrulipase, a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients in cystic fibrosis and chronic pancreatitis patients with exocrine pancreatic insufficiency. Our prior programs consisted of Latiglutenase, a targeted oral biotherapeutic for celiac disease designed to breakdown gluten into non-immunogenic peptides; Capeserod, a selective 5-HT4 receptor partial agonist which was being developed as a gastroparesis therapeutic; and Niclosamide, an oral small molecule with anti-inflammatory properties for patients with inflammatory bowel diseases such as ulcerative colitis and Crohn’s disease. We have determined to discontinue the Latiglutenase, Capeserod and Niclosamide programs.

In March 2024, we announced the closing of a merger with ImmunogenX, Inc. (“IMGX”) (the Company’s acquisition of IMGX, the “Merger”), a private, clinical-stage biopharmaceutical company founded in 2013, which is developing the biologic Latiglutenase for the treatment of celiac disease. As a result of the Merger, IMGX became a limited liability company and our wholly owned subsidiary. As consideration for the Merger we issued the former shareholders of IMGX (A) 36,830 shares of Common Stock of the Company and (B) 11,777.418 shares of Series G Preferred Stock. In addition, we assumed (i) all ImmunogenX stock options immediately outstanding prior to the Merger, each becoming an option to purchase Common Stock subject to adjustment pursuant to the terms of the merger agreement (the “Assumed Options”) and (ii) all ImmunogenX warrants immediately outstanding prior to the Merger, each becoming a warrant to purchase Common Stock subject to adjustment pursuant to the terms of the merger agreement (the “Assumed Warrants”). The Assumed Options are exercisable for an aggregate of 200,652 shares of Common Stock, have an exercise price of $0.81 and expire between February 1, 2031 and June 6, 2033. The Assumed Warrants are exercisable for an aggregate of 127,682 shares of Common Stock, have exercise prices ranging from $3.02 to $3.92 and expire between September 30, 2032 and September 6, 2033.

IMGX is developing CypCel, a metabolic marker compound that can measure the state of small-intestinal recovery of celiac patients undergoing gluten-free diets (“GFDs”). We have initiated a plan to dispose of certain assets and liabilities of IMGX, including Latiglutenase and CypCel. As of December 31, 2024, these were classified as assets and liabilities held for sale and due to the short period of time since the close of the Merger, are reported at their fair value less cost to sell. We determined that the discontinued operations of IMGX represents a strategic shift that will have a major effect on our operations and financial statements.

In March 2025, we announced that we entered into a rescission agreement (the “Rescission Agreement”), by and among the Company, IMGX and the former shareholders of IMGX (the “IMGX Shareholders”). Under the terms of the Rescission Agreement, the parties have amicably determined that it is in their collective best interest to: (i) rescind the issuances of the shares of Common Stock and Series G Preferred Stock that the Company has issued to the IMGX Shareholders as part of the Merger, (ii) convey to the IMGX Shareholders all of the issued and outstanding membership interests (the “Membership Interests”) of IMGX currently held by the Company, (iii) cancel the Assumed Options and Assumed Warrants, and (iv) provide for such additional agreements as are set forth in the Rescission Agreement. Also as set forth in the Rescission Agreement, following the closing, the Company will retain up to approximately $695,000 of IMGX’s accounts payable, and IMGX will remain responsible for approximately $9,278,400 of IMGX’s secured debt. The Company expects that the closing of the Rescission Agreement will occur on or prior to June 30, 2025, subject to satisfaction of all conditions for closing, including obtaining shareholder approval by the Company for the transfer of the Membership Interests to the IMGX Shareholders. After the transactions contemplated by the Rescission Agreement have been consummated, IMGX will no longer be a subsidiary of the Company, and the Company will no longer be holding any interest in IMGX.

On February 26, 2025, we gave notice to terminate our license agreement with Sanofi for the development of Capeserod, a selective 5-HT4 receptor partial agonist. We anticipate that this termination will be effective in April 2025. We may terminate the license agreement by providing Sanofi with at least 60 days prior written notice; provided, however, that Sanofi shall be entitled to any and all payments due and owed to Sanofi prior to the effective date of termination. No payments are due.

In November 2024, we announced a binding term sheet, subject to several closing conditions, for a reverse merger transaction with Journey Therapeutics, Inc. We do not anticipate that this transaction will move forward.

In September 2024, we announced a binding letter of intent with Data Vault Holdings, Inc. (“Data Vault”), a privately held technology holding company, to exclusively license two technology product suites owned by Data Vault. We do not anticipate that this transaction will move forward.

In December 2023, we announced that we had entered into a non-binding term sheet to sell our Niclosamide program. This transaction is not expected to move forward.

Our Product Candidates

Our Adrulipase programs are focused on the development of an oral, non-systemic, biologic capsule for the treatment of exocrine pancreatic insufficiency (“EPI”) in patients with cystic fibrosis (“CF”) and chronic pancreatitis (“CP”). Our goal is to provide CF and CP patients with a safe and effective therapy to control EPI that is non-animal derived and offers the potential to dramatically reduce their daily pill burden. In July 2023, we announced topline results from our Phase 2b monotherapy bridging study using a new enteric microgranule formulation of Adrulipase. Although the primary efficacy endpoint was not achieved, data from the study indicated that the enhanced Adrulipase formulation was safe, well tolerated and demonstrated an improvement over prior formulations of Adrulipase. We are planning to move this program forward in 2025.

Our Latiglutenase program was focused on the development of an orally administered, minimally-absorbed, biologic for improving multiple gluten-induced symptoms and consequent quality of life (“QOL”) due to inadvertent gluten consumption in patients with celiac disease (“CeD”) by breaking down the gluten into non-immunogenic peptides. We are no longer working on this program and have initiated a plan for its disposition.

Our Capeserod program was in-licensed from Sanofi in September 2023. Sanofi conducted Phase 1 and Phase 2 Central Nervous System (“CNS”) trials with over 600 patients. In Sanofi’s CNS trials, Capeserod appeared safe and well-tolerated. Research on Capeserod and subsequent artificial intelligence (“AI”) empowered analyses suggest that the drug possesses a unique mechanism of action that is applicable to several GI indications underserved by currently available therapeutics. We are no longer working on this program and have notified Sanofi on February 26, 2025 of our termination of the license agreement. We may terminate the license agreement with Sanofi by providing Sanofi with at least 60 days prior written notice; provided, however, that Sanofi shall be entitled to any and all payments due and owed to Sanofi prior to the effective date of termination. On February 26, 2025, we provided notice to Sanofi to terminate the license agreement. No payments are due to Sanofi and the Company expects the termination to be effective in April 2025.

Our Niclosamide programs leveraged proprietary oral and topical formulations to address multiple GI conditions, including inflammatory bowel diseases (“IBD”) indications. In 2022 we advanced four separate Phase 2 clinical programs of our Niclosamide formulations, including FW-COV for Severe Acute Respiratory Syndrome Coronavirus 2 (“COVID-19”) GI infections, FW-UP for ulcerative proctitis (“UP”) and ulcerative proctosigmoiditis (“UPS”), FW ICI AC for Immune Checkpoint Inhibitor associated colitis (“ICI AC”), and FW CD for Crohn’s disease. We are no longer actively pursuing these programs.

Our primary drug candidate and clinical program is described below.

Adrulipase

Adrulipase is the active pharmaceutical ingredient (“API”) derived from Yarrowia lipolytica, an aerobic yeast naturally found in various foods such as cheese and olive oil that is widely used as a biocatalyst in several industrial processes. Adrulipase is a secreted lipase naturally produced by Yarrowia lipolytica, known as LIP2, that we are developing through recombinant DNA technology for the treatment of EPI associated with CF and CP. Lipases are enzymes that help with the digestion of lipids and fat.

We previously held the exclusive right to commercialize Adrulipase in the U.S., Canada, South America (excluding Brazil), Asia (excluding China and Japan), Australia, New Zealand and Israel pursuant to a sublicense from Laboratories Mayoly Spindler SAS (“Mayoly”) under the Joint Research and Development Agreement (“JDLA”), which also granted us joint commercialization rights for Brazil, Italy, China and Japan. In March 2019, we purchased all rights, title and interest in and to Adrulipase from Mayoly pursuant to the Mayoly Asset Purchase Agreement (“APA”), provided, however, Mayoly retained exclusive commercial rights in France and Russia.

Background

The pancreas is both an endocrine gland that produces several important hormones, including insulin, glucagon, and pancreatic polypeptide, as well as a digestive organ that secretes pancreatic juice containing digestive enzymes that assist with the absorption of nutrients and digestion in the small intestine.

The targeted indication of Adrulipase is the treatment of EPI, which is observed when the exocrine functions of the pancreas are below 10% of normal. The symptomatology of EPI is essentially due to the deficiency of pancreatic lipase, an enzyme that hydrolyses triglycerides into monoglycerides and free fatty acids. The pancreatic lipase enzymatic activity is hardly compensated by extra-pancreatic mechanisms, because gastric lipase has nearly no lipolytic activity in the pH range of the intestine. On the other hand, when they are impaired, the pancreatic amylase and protease (enzymes that break up carbohydrates (starches) and proteins, respectively) activities can be compensated by the salivary amylase, the intestinal glycosidase, the gastric pepsin, and the intestinal peptidases, all of which are components of the gastric juice secreted by the stomach walls. Lipid maldigestion due to lipase deficiency is responsible for weight loss, steatorrhea featured by greasy diarrhea, and fat-soluble vitamin deficiencies (i.e. A, D, E and K vitamins).

CP, the most common cause of EPI, is a long-standing inflammation of the pancreas that alters its normal structure and functions. In the U.S., its prevalence rate is of 42 cases per 100,000 inhabitants, resulting in approximately 132,000 cases. Approximately 60% of patients affected with CP display EPI, resulting in approximately 90,000 patients requiring substitution therapy in the U.S. In Western societies, CP is caused by chronic alcoholic consumption in approximately 55-80% of cases. Other relatively frequent etiologies include the genetic form of the disease that is inherited as an autosomal dominant condition with variable penetrance, pancreatic trauma and idiopathic causes.

CF, another dominant etiology of EPI, is a severe genetic disease associated with chronic morbidity and life-span decrease of most affected individuals. In most Caucasian populations, CF prevalence is of 7-8 cases per 100,000 inhabitants, but is less common in other populations, resulting in more than 30,000 affected individuals in the U.S. and more than 70,000 affected individuals worldwide. CF is inherited as monogenic autosomal recessive disease due to the defect at a single gene locus that encodes the Cystic Fibrosis Transmembrane Regulator protein, or CFTR, a regulated chloride channel. Mutation of both alleles of this chloride channel gene results in the production of thick mucus, which causes a multisystem disease of the upper and lower respiratory tracts, digestive system, and the reproductive tract. The progressive destruction of the pancreas results in EPI that is responsible for malnutrition and contributes to significant morbidity and mortality. About 80-90% of patients with CF develop EPI, resulting in approximately 25,000-27,000 patients in the U.S. that require substitution therapy.

Current treatments for EPI stemming from CP and CF rely on porcine (pig derived) pancreatic enzyme replacement therapies (“PERTs”), which have been on the market since the late 1800s. PERTs are typically comprised of three digestive enzymes; lipases, proteases, and amylases. The PERT market is well established with estimated sales of approximately $1.4 billion in 2019 in the U.S. and has been growing for the past five years at a compound annual growth rate of approximately 20%. In spite of their long-term use, however, PERTs suffer from poor stability, formulation problems, possible transmission of conventional and non-conventional infectious agents due to their animal origins, and possible adverse events at high doses in patients with CF and limited effectiveness.

Pre-Clinical Program

The efficacy of Adrulipase has been investigated in normal minipigs, which are generally considered to be a relevant model for digestive drug development because of their physiological similarities with humans and their omnivorous diet. Experimental pancreatitis was induced by pancreatic duct ligation, resulting in severe EPI with baseline CFA around 60% post-ligature. CFA is a measurement obtained by quantifying the amount of fat ingested orally over a defined time period and subtracting the amount eliminated in the stool to ascertain the amount of fat absorbed by the body. Pigs were treated with either Adrulipase or enteric-coated PERTs, both administered as a single-daily dose.

At doses ranging from 10.5 to 211 mg, Adrulipase increased the CFA by +25 to +29% in comparison to baseline (p<0.05 at all doses), whereas the 2.5 mg dose had milder activity. Similar efficacy was observed in pigs receiving 100,000 U lipase of enteric-coated porcine pancreatic extract. These findings demonstrate the in vivo activity of Adrulipase in a relevant in vivo model at a level similar to the PERTs at dosages of 10.5mg or greater.

Table of Contents

To date, two non-clinical toxicology studies have been conducted. Both show that Adrulipase lipase is clinically well tolerated at levels up to 1000mg/kg in rats and 250 mg/kg in minipigs up to 13 weeks. Adrulipase is therefore considered non-toxic in both rodent and non-rodent species up to a maximum feasible dose of 1,000 mg/kg/day in the rats over six months of administration.

Clinical Program

We are developing Adrulipase for two principal therapeutic indications: (i) children and adults affected by CF, and (ii) adult patients with CP. We have determined to initially pursue the adult indication in CF.

Chronic Pancreatitis

During 2010 and 2011, a phase 1/2a clinical trial of Adrulipase was conducted in conjunction with Mayoly in a single center in France. The study was an exploratory study mainly designed to investigate the safety of Adrulipase and was a randomized, double blind, placebo controlled, parallel clinical trial in 12 patients affected with CP or pancreatectomy and severe EPI. The primary efficacy endpoint of the study was defined as the relative change in steatorrhea (an established surrogate biomarker of EPI correction) in comparison to baseline. The study found that Adrulipase was well tolerated with no serious adverse events. Only two adverse events were observed: constipation (two patients out of eight with Adrulipase) and hypoglycemia (two patients out of eight with Adrulipase, and one patient out of four with placebo). A non-statistically significant difference of the primary endpoint, possibly due to the small group size, was found between the two groups both in intention-to-treat, a group that included three patients who received the in-patient facility study diet but did not fulfill the protocol’s inclusion criteria, and per-protocol analysis. This study was not designed, nor did it aim to demonstrate statistically significant changes of CFA or steatorrhea under Adrulipase.

We received regulatory approval in Australia and New Zealand in 2016, with the addition of a 2018 regulatory approval in France, to conduct a Phase 2 multi-center dose escalation study of Adrulipase in CP and pancreatectomy. The primary endpoint of this study was to evaluate the safety of escalating doses of Adrulipase in 11 CP patients. The secondary endpoint was to investigate the efficacy of Adrulipase in these patients by analysis of the CFA and its change from baseline. In September 2018, we announced that in pre-planned analyses, both the study’s primary and secondary endpoints were reached with a statistically significant (p=0.002) improvement in the CFA of 21.8%, in a per protocol analysis, with the highest evaluated dose of 2,240 mg/day of Adrulipase. The statistical significance of the trial results is typically based on widely used, conventional statistical methods that establish the p-value of the results. A p-value of 0.05 or less is required to demonstrate statistical significance. As such, these CFA levels are considered to be statistically significant.

Cystic Fibrosis Monotherapy

In October 2018, the FDA cleared our IND application for Adrulipase in patients with EPI due to CF. In December 2018, we initiated the Phase 2 OPTION Bridging Dose Study to investigate Adrulipase in CF patients with EPI and in February 2019, we dosed the first patients. The Phase 2 OPTION Bridging Dose Study investigated the safety, tolerability and efficacy of Adrulipase in a head-to-head comparison against the current PERT standard of care. The OPTION Bridging Dose Study employed a six-week non-inferiority CFA primary efficacy endpoint comparing Adrulipase to PERTs.

In September 2019, we announced positive results from the OPTION Bridging Dose Study. Results showed that the primary efficacy endpoint of CFA was comparable to the CFA in a prior Phase 2 study in patients with CP, while using the same dosage of Adrulipase. The dosage used in the OPTION Bridging Dose Study was 2.2 grams per day, which was determined in agreement with the FDA as a bridging dose from the highest safe dose used in the Phase 2 CP dose escalation study. Although the study was not powered for statistical significance, the data demonstrated meaningful efficacy results, with approximately 50% of the patients showing CFAs high enough to reach non-inferiority with standard PERTs. Additionally, the CNA was comparable between the Adrulipase and PERT arms, 93% vs. 97%, respectively, in the OPTION Bridging Dose Study. This important finding confirms that protease supplementation is not likely to be required with Adrulipase treatment. A total of 32 patients, ages 18 or older, completed the OPTION Bridging Dose Study.

In October 2019, the CFF DSMB completed its review of our final results of the OPTION Bridging Dose Study and found no safety concerns for Adrulipase and supported our plan to proceed to the Phase 2b OPTION 2 Trial. In December 2019, we submitted the clinical trial protocol to the existing IND at the FDA. In April 2020, we received approval to conduct the OPTION 2 Trial in Therapeutics Development Network clinical sites in the U.S.

Table of Contents

The OPTION 2 Trial was designed to investigate the safety, tolerability and efficacy of Adrulipase (2.2 gram and 4.4 gram doses in enteric capsules) head-to-head versus the current standard of care, PERT pills. The OPTION 2 Trial was an open-label, crossover study, conducted in 15 sites in the U.S. and Europe. Enrollment included a total of 30 CF patients 18 years or older. Adrulipase was administered in enteric capsules to provide gastric protection and test for optimal delivery of enzyme to the duodenum. Patients were first randomized into two cohorts: the Adrulipase arm, where they received a 2.2 gram daily oral dose of Adrulipase for three weeks; or the PERT arm, where they received their pre-study dose of PERT pills for three weeks. After three weeks, stools were collected for analysis of CFA. Patients were then crossed over for another three weeks of the alternative treatment. After three weeks of cross-over therapy, stools were again collected for analysis of CFA. A parallel group of patients was randomized and studied in the same fashion using a 4.4 gram daily dose of Adrulipase. All patients were followed for an additional two weeks after completing both crossover treatments for post study safety observation. Patients were assessed using descriptive methods for efficacy, comparing CFA between Adrulipase and PERT arms, and for safety.

In January 2021, we announced an additional study arm in OPTION 2 Trial using an immediate release Adrulipase capsules in order to identify the optimal dose and delivery method of Adrulipase. This extension phase tested patients 18 years or older, who have already completed the crossover phase, at higher doses relative to the previously conducted OPTION Bridging Dose Study. This allowed us to compare data from the existing crossover arm using enteric (delayed release) capsules with data from the new immediate release extension arm.

In March 2021 we announced topline OPTION 2 data. The trial demonstrated that Adrulipase was safe and well-tolerated and data from OPTION 2, and the other Adrulipase Phase 2 clinical trials, demonstrated drug activity. However, OPTION 2 did not consistently meet the primary efficacy endpoint. Some patients were able to achieve CFA at levels beyond what is required to demonstrate non-inferiority with PERT therapies, but the majority did not.

We believe that the underlying cause of the drug’s uneven efficacy performance in the OPTION 2 trial was the enteric capsule formulation. While the enteric coating protected the capsule from breaking down in the stomach acid, it also appeared to dissolve too slowly in the small intestine to release the lipase enzyme in time to aid with proper digestion and nutrient absorption.

In August 2021 we announced that we would begin development of a new enteric microgranule formulation of Adrulipase. The new formulation is planned to be administered with food as an oral capsule that dissolves in the stomach and disperses acid-resistant micro-granules that thoroughly mix with food during the digestion process. The resultant mixture then passes to the small intestine where the lipase enzyme breaks up fat molecules so that they can be absorbed. We completed the reformulation work in the second half of 2022.

In November 2022 we announced that we had filed an IND amendment with the FDA for a Phase 2b bridging study with the new enteric microgranulation formulation of Adrulipase. The new trial is designed to investigate the safety, tolerability and efficacy of the new formulation of Adrulipase. It is an open-label study that will be conducted at three sites in the U.S. A total of 12 cystic fibrosis patients, 18 years or older are expected to be enrolled. The trial design employs a dose titration strategy. Patients will be screened at baseline to ensure that they have a coefficient of fat absorption (CFA) of at least 80%. Eligible patients will then be switched from their commercial enzyme product to Adrulipase. Each patient will be started on a low dose of Adrulipase. If the patient is not clinically controlled, the patient will be switched to a medium dose, and if not controlled on this dose, the patient will be advanced to a high dose. The titrations will be carried out over a three-week period, after which a CFA will be obtained. End of study CFAs will be compared to the baseline CFAs in a descriptive fashion. A post treatment safety visit will be conducted one week after completing the treatment period.

Following FDA review of the IND amendment, we initiated the Phase 2b pilot monotherapy trial during the first quarter of 2023 and received topline data in the third quarter of 2023. Although the primary efficacy endpoint was not achieved, data from the study indicated that the enhanced Adrulipase formulation was safe, well tolerated and demonstrated an improvement over prior formulations of Adrulipase. We are planning to move this program forward in 2025 including with the intent to initiate a Ph2b clinical trial in the second half of 2025.

Combination Therapy

We launched the Phase 2 Combination Trial in Hungary in July 2019 to investigate Adrulipase, in combination with PERT, in CF patients who suffer from severe EPI but continue to experience clinical symptoms of fat malabsorption despite taking the maximum daily dose of PERTs. The Combination Trial is designed to investigate the safety, tolerability and efficacy of escalating doses of

Adrulipase (700 mg, 1120 mg and 2240 mg per day, respectively), in conjunction with a stable dose of PERTs, in order to increase CFA and relieve abdominal symptoms. In October 2020, we opened a total of five clinical sites in Turkey and dosed the first patients in November 2020. In March 2021, we reached targeted minimum enrollment of 18 patents.

We announced positive interim data on the first five patients in the Combination Trial in August 2020. The primary efficacy endpoint was met, with CFAs greater than 80% for all patients across all visits. For secondary efficacy endpoints, we observed that stool weight decreased, the number of stools per day decreased, steatorrhea improved, and body weight increased. Additionally, no serious adverse events were reported.

In August 2021, we announced topline data collected from the 20 patients enrolled in the study. The data indicated that Adrulipase in combination with PERT led to clinically meaningful improvements in CFA, the primary efficacy endpoint. Patients showed an average gain of more than six percentage points from baseline, compared to the five-point improvement in CFA cited by the clinical literature as clinically significant. The study also demonstrated positive improvements in weight gain and other secondary endpoints.

We believe a combination therapy of PERT and Adrulipase has the potential to: (i) correct macronutrient and micronutrient maldigestion; (ii) eliminate abdominal symptoms attributable to maldigestion; and (iii) sustain optimal nutritional status on a normal diet in CF patients with severe EPI.

License Agreement with Sanofi

On February 26, 2025, we gave notice to terminate our license agreement with Sanofi for the development of Capeserod, a selective 5-HT4 receptor partial agonist. We anticipate that this termination will be effective in April 2025. We may terminate the license agreement by providing Sanofi with at least 60 days prior written notice; provided, however, that Sanofi shall be entitled to any and all payments due and owed to Sanofi prior to the effective date of termination. No payments are due to Sanofi.

Revolving Loan Agreement

Effective January 31, 2025, we entered into a Revolving Loan Agreement dated January 27, 2025 (the “Revolving Loan Agreement”), with a Lender pursuant to which the Lender agreed to make loans to us. Pursuant to and under the terms of the Revolving Loan Agreement, we issued to the Lender a revolving note dated January 27, 2025 in the principal amount of $2,000,000 (the “Revolving Note” and such amount, the “Total Outstanding Amount”). This transaction is referred to as the “Financing”. The Company shall use the proceeds from the Financing for general corporate purposes, including but not limited to finance the expense of a Qualified Public Equity Offering (as defined below) and payment of certain items. Out of the Total Outstanding Amount, the Lender disbursed an initial loan amount of $550,000 to the Company on January 31, 2025.

The Revolving Note bears interest at the rate of 18% per annum calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall accrue daily commencing on January 31, 2025 until paid in full. The outstanding principal balance of all outstanding loans under the Financing, all accrued and unpaid interest and all other amounts, costs, expenses and/or liquidated damages are due in full on January 31, 2026. The Revolving Loan Agreement contains customary events of default. If an event of default occurs, the Lender may accelerate the indebtedness under the Revolving Loan Agreement, and an amount equal to 120% of the of the outstanding principal amount and accrued and unpaid interest plus liquidated damages and other amounts, costs, expenses and/or liquidated damages due under or in respect of the Loan Documents (as defined under the Revolving Loan Agreement) for the Financing, if any.

The Revolving Loan Agreement provides that it is a condition of the closing of the Financing that not less than three of the current members of our Board of Directors resign and that three nominees designated by the Lender (“Lender Board Member Candidates”) be appointed to the Board of Directors by the remaining members of the Board of Directors. The Revolving Loan Agreement also provides that we will use our reasonable best efforts to consummate an underwritten or “best efforts” public offering of not less than $5,000,000 by us of our Common Stock and/or any convertible security or warrant, option or other right to subscribe for or purchase any additional shares of our Common Stock (“Qualified Public Equity Offering”) as soon as practicable, and the Lender shall cooperate with us in connection therewith. If, despite the reasonable best efforts of the Borrower, (x) a registration statement with respect to securities to be offered in a Qualified Public Equity Offering (the “QPEO S-1”) is not filed within 45 days following the initial Closing Date, or (y) a Qualified Public Equity Offering is not consummated within the earlier of (A) 120 days from the initial filing of the QPEO S-1 and (B) 30 days of a QPEO S-1 being declared effective by the SEC, then the Lender Board Member Candidates shall, upon the written request of the remaining members of the Board of Directors, resign from all of their respective positions on the Board of Directors.

Letter of Intent with Data Vault Holdings, Inc.

On September 9, 2024, we entered into the Letter of Intent with Data Vault Holdings, Inc. (“DVHI”) for the licensing of certain clinical trial software owned by DVHI and associated intellectual property (the “Assets”). The Letter of Intent contemplates a worldwide exclusive license to the Assets with the right to grant sublicenses, and a right of first refusal for the Company to fully acquire the Assets in exchange for the issuance of $250,000 of shares of the Company’s junior convertible preferred stock (the “Preferred Shares”) priced at a price per preferred share equal to 180% of the five (5) trading day Volume-Weighted Average Price (“VWAP”) of the Company’s Common Stock (the “Common Share Price”), immediately preceding the closing of the Proposed Transaction multiplied by 1,000 (the “Preferred Share Price”), and single digit royalties on net sales (the “Proposed Transaction”). Entry into definitive documentation for the Proposed Transaction will be conditioned upon the Company receiving no less than $500,000 of strategic investment (the “Strategic Investment”), with a target of ultimately securing up to $3.0 million of strategic investment with the assistance of DVHI. There can be no assurance that the Proposed Transaction will be completed on the terms contemplated in the Letter of Intent or otherwise. We do not anticipate that this transaction will move forward.

Nasdaq Listing Compliance

We received a letter on September 6, 2024 from the Listing Qualifications Staff of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the closing bid price of our Common Stock for the last 30 consecutive business days, the Company was not in compliance with the requirement to maintain a minimum bid price of $1.00 per share for continued listing on The Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), we were provided 180 days, or until March 5, 2025, to regain compliance with the minimum bid price requirement.

On March 6, 2025, we received a letter from Nasdaq advising that we had been granted a 180-day extension, or until September 1, 2025, to regain compliance with the minimum bid price requirement, in accordance with Nasdaq Listing Rule 5810(c)(3)(A). If at any time prior to September 1, 2025, the bid price of our Common Stock closes at $1.00 per share or more for a minimum of 10 consecutive trading days, we will regain compliance with the minimum bid price requirement.

The extension notice has no immediate effect on the listing of our Common Stock on The Nasdaq Capital Market and does not affect our reporting requirements with the Securities and Exchange Commission. If we do not regain compliance with the minimum bid price requirement during the additional 180-day extension, Nasdaq will provide written notification that our Common Stock will be delisted. At that time, we may appeal the delisting determination to a hearings panel pursuant to the procedures set forth in the applicable Nasdaq Listing Rules. However, there can be no assurance that, if the Company does appeal the delisting determination by Nasdaq to the hearings panel, that such appeal would be successful. There can be no assurance that we will regain compliance with the minimum bid price requirement during the additional 180-day compliance period ending September 1, 2025 or maintain compliance with any other Nasdaq listing requirement. We intend to monitor the closing bid price of our Common Stock and may, if appropriate, consider implementing available options to regain compliance with the minimum bid price requirement.

On January 7, 2025, we received a written notice from the Listing Qualifications department of Nasdaq indicating that were not in compliance with Nasdaq Listing Rule 5620(a), due to us not holding an annual meeting of stockholders in 2024 within one year of our 2023 fiscal year end. On February 21, 2025, we submitted a plan to regain compliance. On March 3, 2025, Nasdaq informed us that it has determined to grant us an extension until June 30, 2025 to regain compliance for continued listing.

Corporate History

We were incorporated on January 30, 2014 in the State of Delaware under the name AzurRx BioPharma, Inc. In May 2014, we entered into a stock purchase agreement with Protea Biosciences Group, Inc. (“Protea Group”) and its wholly-owned subsidiary, Protea Biosciences, Inc. (“Protea Sub” and, together with Protea Group, “Protea”), to acquire 100% of the outstanding capital stock of AzurRx SAS (formerly ProteaBio Europe SAS), a wholly-owned subsidiary of Protea Sub, which was completed in June 2014. In October 2016, we completed an initial public offering, which allowed us to list our shares of Common Stock on the Nasdaq Capital Market.

On September 13, 2021, we completed the acquisition of First Wave Bio, Inc. (“FWB”), which became our wholly-owned subsidiary. In connection with the acquisition, AzurRx BioPharma, Inc. changed its name to First Wave BioPharma, Inc.

Effective October 26, 2022, the AzurRx SAS subsidiary was dissolved.

In May 2024, we changed our name from First Wave Biopharma, Inc. to Entero Therapeutics, Inc.

On March 24, 2025, we entered into a Rescission Agreement with IMGX and the IMGX Shareholders. After the Rescission Agreement will Closed, IMGX will no longer be a subsidiary of the Company, and the Company will no longer be holding any interest in IMGX.

Intellectual Property

Our goal is to obtain, maintain and enforce patent protection for our product candidates, formulations, processes, methods and any other proprietary technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United States and in other countries. Our policy is to actively seek to obtain, where appropriate, the broadest intellectual property protection possible for our current product candidates and any future product candidates, proprietary information and proprietary technology through a combination of contractual arrangements and patents, both in the United States and abroad. However, patent protection may not afford us with complete protection against competitors who seek to circumvent our patents.

We also depend upon the skills, knowledge, experience and know-how of our management and research and development personnel, as well as that of our advisors, consultants and other contractors. To help protect our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we currently rely and will in the future rely on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all of our employees, consultants, advisors and other contractors to enter into confidentiality agreements that prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

Adrulipase

The Adrulipase program is protected by the following issued patents that we had originally licensed under the Mayoly Agreement and now own:

In addition, PCT International application was filed in 2021 directed to our proprietary formulation of Adrulipase that has been filed in the United States and certain foreign countries. Any patents issuing from these filings will have an expected expiration in 2041.

PCT International applications were filed in 2022 and nationalized in certain foreign countries outside of the U.S to stable lipase formulations and methods of treatment. Any patents issuing from these filings will have an expected expiration in 2042. These patents are not pending in the U.S.

PCT International Application was filed in 2023 directed to Adrulipase formulations. Any patents issuing from this filing will have an expected expiration in 2043.

We also expect to receive 12-year biologic exclusivity in the United States under the Affordable Care Act and 10-year data exclusivity in the European Union for Adrulipase.

Latiglutenase

The Latiglutenase program is protected by U.S. Patent 10,434,150 that expires July 3, 2035, U.S. Patent 8,980,254 that expires April 10, 2030, and U.S. Patent 9,993,531 that expires Sept. 9, 2029.

Manufacturing

We currently outsource all manufacturing, and we intend to use our collaborators and contract development and manufacturing organizations (“CDMOs”) for the foreseeable future.

Adrulipase

Adrulipase API, including drug substance and drug product, is currently manufactured by Asymchem, Inc. at a contract facility located in Tianjin, China. Charles River Laboratories based in Malvern, Pennsylvania is responsible for maintaining our master and working cell banks. We believe there are multiple alternative contract manufacturers capable of producing the product we need for clinical trials; however, there is no guarantee that the processes are easily reproducible and transferrable.

Competition

The pharmaceutical and biotechnology industries are characterized by rapidly evolving technology and intense competition. Many companies of all sizes, including major pharmaceutical companies and specialized biotechnology companies, are engaged in the development and commercialization of therapeutic agents designed for the treatment of the same diseases and disorders that we target. Many of our competitors have substantially greater financial and other resources, larger research and development staff and more experience in the regulatory approval process. Moreover, potential competitors have or may have patents or other rights that conflict with patents covering our technologies.

Adrulipase

With respect to Adrulipase, if approved, we would compete with PERTs (pancrelipase), a well-established market that is currently dominated by a few large pharmaceutical companies, including CREON® marketed by AbbVie Inc., ZENPEP® sold to Nestlé S.A. by Allergan plc. in January 2020, PANCREAZE® marketed byVIVUS, Inc. and PERTZYE® marketed by Chiesi Farmaceutici S.p.A. There are currently six PERT products that have been approved by the FDA for sale in the U.S. We believe our ability to compete in this market, if we are successful in developing and obtaining regulatory approval to market Adrulipase, will depend on our ability (or that of a future corporate partner) to convince patients, their physicians, healthcare payors and the medical community of the benefits of using a non-animal-based product to treat EPI, as well as by addressing other shortcomings associated with PERTs, including a large pill burden.

Government Regulation and Product Approval

Government authorities in the United States, at the federal, state and local level, and other countries extensively regulate, among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping,

-10-

Table of Contents

promotion, advertising, distribution, post-approval monitoring and reporting, marketing and export and import of products such as those we are developing. To date, our internal research and development efforts have been conducted in France. We expect to conduct late-stage development work, including clinical trials for Adrulipase in both the United States and Europe, as North America is our principal target market for our product candidates that we may successfully develop.

U.S. Government Regulation

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its implementing regulations, and biologics under the FDCA and the Public Health Service Act, or PHSA, and its implementing regulations. FDA approval is required before any new unapproved drug or dosage form, including a new use of a previously approved drug, can be marketed in the United States. Drugs and biologics are also subject to other federal, state and local statutes and regulations. If we fail to comply with applicable FDA or other requirements at any time during the drug development process, clinical testing, the approval process or after approval, we may become subject to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, license suspension or revocation, withdrawal of an approval, warning letters, product recalls, product seizures, placement on Import Alerts, debarment of personnel, employees or officers, total or partial suspension of production or distribution, injunctions, fines, civil penalties or criminal prosecution.

The process required by the FDA before product candidates may be marketed in the United States generally involves the following:

An IND is a request for authorization from the FDA to administer an investigational new drug product to humans. The central focus of an IND submission is on the general investigational plan and the protocol(s) for human studies. The IND also includes results of animal and in vitro studies assessing the toxicology, pharmacokinetics, pharmacology and pharmacodynamic characteristics of the product; chemistry, manufacturing and controls information; and any available human data or literature to support the use of the investigational new drug. An IND must become effective before human clinical studies may begin. An IND will automatically become effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to the proposed clinical studies. In such a case, the IND may be placed on clinical hold and the IND sponsor and the FDA must resolve any outstanding concerns or questions before clinical studies can begin. Accordingly, submission of an IND may or may not result in the FDA allowing clinical studies to commence.

-11-

Table of Contents

Clinical Studies

Clinical studies involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical study. Clinical studies are conducted under protocols detailing, among other things, the objectives of the study, and the parameters to be used in monitoring safety and the efficacy criteria to be evaluated. A protocol for each clinical study and any subsequent protocol amendments must be submitted to the FDA as part of the IND. Additionally, approval must also be obtained from each clinical study site’s IRB before the studies may be initiated, and the IRB must monitor the study until completed. There are also requirements governing the reporting of ongoing clinical studies and clinical study results to public registries, such as ClinicalTrials.gov.

The clinical investigation of a drug or biologic is generally divided into three or four phases. Although the phases are usually conducted sequentially, they may overlap or be combined.

A confirmatory or pivotal study is a clinical study that adequately meets regulatory agency requirements for the evaluation of a drug candidate’s efficacy and safety such that it can be used to justify the approval of the product. Generally, pivotal studies are Phase 3 studies, but the FDA may accept results from Phase 2 studies if the study design provides a well-controlled and reliable assessment of clinical benefit, particularly in situations where there is an unmet medical need and the results are sufficiently robust. In such cases, FDA may require post-market studies for safety and efficacy to be conducted for the drug candidate. The FDA may withdraw the approval if the results indicate that the approved drug is not safe or effective.

The FDA, the IRB or the clinical study sponsor may suspend or terminate a clinical study at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Additionally, some clinical studies are overseen by an independent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board or committee. This group provides authorization for whether or not a study may move forward at designated check points based on access to certain data from the study. We may also suspend or terminate a clinical study based on evolving business objectives and/or competitive climate.

Chemistry, Manufacturing and Control Information

Companies seeking FDA approval of drugs must also develop data and information about the physical characteristics of the components of a product as well as finalize processes for manufacturing the components in commercial quantities in accordance with GMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of the final product. Additionally, appropriate packaging must be selected and tested, and stability studies must be conducted to demonstrate that the components of a product candidate do not undergo unacceptable deterioration over their shelf life.

Submission of an NDA or BLA to the FDA

Assuming successful completion of all required testing in accordance with all applicable regulatory requirements, detailed investigational new drug product information is submitted to the FDA in the form of an NDA or BLA requesting approval to market the product for one or more indications. Under federal law, the submission of most NDAs and BLAs is subject to a substantial application user fee. Applications for orphan drug products are exempted from the NDA and BLA application user fees.

An NDA or BLA must include all relevant data available from pertinent preclinical and clinical studies, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical studies intended to test the safety and effectiveness of a use of a product, or from a number of alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational product to the satisfaction of the FDA.

Once an NDA or BLA has been submitted, the FDA’s goal is to review the application within ten months after it accepts the application for filing, or, if the application relates to an unmet medical need in a serious or life-threatening indication, six months after the FDA accepts the application for filing. The review process is often significantly extended by FDA requests for additional information or clarification.

Before approving an NDA or BLA, the FDA typically will inspect the facility or facilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP.

The FDA is required to refer an application for an investigational drug or biologic to an advisory committee or explain why such referral was not made. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the investigational product application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions and typically follows such recommendations.

The FDA’s Decision on an NDA or BLA

After the FDA evaluates the NDA or BLA and conducts inspections of manufacturing facilities, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug or biologic with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete, and the application is not ready for approval. A Complete Response Letter may require additional clinical data and/or an additional pivotal Phase 3 clinical study(ies), and/or other significant, expensive and time-consuming requirements related to clinical studies, preclinical studies or manufacturing. Even if such additional information is submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. The FDA could also approve the NDA or BLA with a REMS to mitigate risks, which could include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. The FDA also may condition approval on, among other things, changes to proposed labeling, development of adequate controls and specifications or a commitment to conduct one or more post-market studies or clinical studies. Such post-market testing may include Phase 4 clinical studies and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization. The FDA may have the authority to withdraw its approval if post-market testing fails to verify the approved drug’s clinical benefit, if the applicant does not perform the required testing with due diligence, or if the any other evidence demonstrates the approved drug is not safe or effective, among other reasons. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our products under development.

Expedited Review and Accelerated Approval Programs

The FDA has various programs, including fast track designation, breakthrough therapy designation, accelerated approval, regenerative medicine advanced therapy and priority review, that are intended to expedite the development and approval of new drugs and biologics that address unmet medical needs in the treatment of serious or life-threatening diseases and conditions. To be eligible for a fast-track designation, the FDA must determine, based on the request of a sponsor, that a product is intended to treat a serious or life-

-13-

Table of Contents

threatening disease or condition and demonstrates the potential to address an unmet medical need. The FDA may review sections of the NDA for a fast-track product on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the NDA, the FDA agrees to accept sections of the NDA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the NDA.

The FDA may give a priority review designation to drugs that offer major advances in treatment or provide a treatment where no adequate therapy exists. A priority review means that the goal for the FDA to review an application is six months, rather than the standard review of ten months under current. These six and ten-month review periods are measured from the “filing” date rather than the receipt date for NDAs for new molecular entities, which typically adds approximately two months to the timeline for review and decision from the date of submission. Most products that are eligible for fast-track designation are also likely to be considered appropriate to receive a priority review.

In addition, products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may be eligible for accelerated approval and may be approved on the basis of adequate and well-controlled clinical studies establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require a sponsor of a drug receiving accelerated approval to perform post-marketing studies to verify and describe the predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the drug may be subject to accelerated withdrawal procedures.

Moreover, under the provisions of the FDA Safety and Innovation Act passed in July 2012, a sponsor can request designation of a drug candidate as a “breakthrough therapy.” A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition, and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Drugs designated as breakthrough therapies are also eligible for the other expedited review and approval programs, including accelerated approval, priority review, regenerative medicine advanced therapy, and fast-track designation. The FDA must take certain actions, such as holding timely meetings and providing advice, intended to expedite the development and review of an application for approval of a breakthrough therapy.

In addition, the 21st Century Cures Act in 2016 made the Regenerative Medicine Advanced Therapy, or RMAT, designation available for investigational drugs that are intended to treat, modify, reverse, or cure a serious condition, with preliminary clinical evidence indicating that the drug has the potential for addressing unmet medical needs for such condition. The RMAT designation is available for cell therapy, therapeutic tissue engineering products, human cell and tissue products, and combination products that use such therapies or products. The advantages of RMAT designation include those of breakthrough and fast track designations, such as early interactions with FDA and rolling review of applications, and the drug candidate with the RMAT designation may be eligible for accelerated approval. Requests for RMAT designations should be made with the IND application (if preliminary clinical evidence is available), but no later than the end-of-phase-2 meeting.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

Post-Approval Requirements

Drugs and biologics marketed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims are subject to prior FDA review and approval. There also are continuing, annual user fee requirements.

Manufacturers are subject to periodic unannounced inspections by the FDA and state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and, depending on the significance of the change, may require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon us and any third-party manufacturers that we may decide to use.

Table of Contents

Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance.

Discovery of previously unknown problems with a product or the failure to comply with applicable requirements may result in restrictions on a product, manufacturer or holder of an approved NDA or BLA, including withdrawal or recall of the product from the market or other voluntary, FDA-initiated or judicial action that could delay or prohibit further marketing. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our products under development.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things.

● restrictions on the marketing or manufacturing of the product;

● complete withdrawal of the product from the market or product recalls;

● fines, warning letters or holds on post-approval clinical studies;

● injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability.

Orphan Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a disease or condition with a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States and when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting a BLA or NDA. After the FDA grants orphan drug designation, the generic identity of the therapeutic agent and its potential orphan use are disclosed publicly by the FDA.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan product marketing exclusivity, which means that the FDA may not approve any other applications, including a full BLA, to market the same biologic for the same use or indication for seven years, except in limited circumstances, such as a showing of clinical superiority to the product with orphan drug exclusivity or if FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which the drug was designated. Orphan drug exclusivity does not prevent the FDA from approving a different drug or biologic for the same disease or condition, or the same drug or biologic for a different disease or condition. Among the other benefits of orphan drug designation are tax credits for certain research and a waiver of the BLA or NDA application user fee.

-15-

Table of Contents

A designated orphan drug may not receive orphan drug exclusivity if it is approved for a use that is broader than the indication for which it received orphan designation. In addition, orphan drug exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation was materially defective or, as noted above, if the second applicant demonstrates that its product is clinically superior to the approved product with orphan exclusivity or the manufacturer of the approved product is unable to assure sufficient quantities of the product to meet the needs of patients with the rare disease or condition.

Biosimilars and Exclusivity

The Affordable Care Act, signed into law in 2010, includes a subtitle called the Biologics Price Competition and Innovation Act of 2009, or BPCIA, which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product. To date, only a handful of biosimilars have been licensed under the BPCIA, although numerous biosimilars have been approved in Europe. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.

Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity and potency, can be shown through analytical studies, human PK and PD studies, clinical immunogenicity assessments, animal studies and a clinical study or studies. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biologic and the reference biologic may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biologic. However, complexities associated with the larger, and often more complex, structures of biological products, as well as the processes by which such products are manufactured, pose significant hurdles to implementation of the abbreviated approval pathway that are still being worked out by the FDA.

Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing that applicant’s own preclinical data and data from adequate and well-controlled clinical studies to demonstrate the safety, purity and potency of its product. The BPCIA also created certain exclusivity periods for biosimilars approved as interchangeable products. At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readily substituted by pharmacies, which are governed by state pharmacy law.

A biological product can also obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study.

The BPCIA is complex and continues to be interpreted and implemented by the FDA. In addition, recent government proposals have sought to reduce the 12-year reference product exclusivity period. Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation. As a result, the ultimate impact, implementation, and impact of the BPCIA is subject to significant uncertainty.

Hatch-Waxman Amendments and Exclusivity

Section 505 of the FDCA describes three types of marketing applications that may be submitted to the FDA to request marketing authorization for a new drug. Section 505(b)(1) NDA is an application that contains full reports of investigations of safety and efficacy. A 505(b)(2) NDA is an application that contains full reports of investigations of safety and efficacy but where at least some of the information required for approval comes from investigations that were not conducted by or for the applicant and for which the applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted. This regulatory pathway enables the applicant to rely, in part, on the FDA’s prior findings of safety and efficacy for an existing product, or published literature, in support of its application. Section 505(j) establishes an abbreviated approval process for a generic version of approved drug products through the submission of an ANDA. An ANDA provides for marketing of a generic drug product that has the same active ingredients, dosage form, strength, route of administration, labeling, performance characteristics and intended use, among other things, to a previously approved product. ANDAs are termed “abbreviated” because they are generally not required to include preclinical (animal) and clinical (human) data to establish safety and efficacy. Instead, generic applicants must scientifically demonstrate that their product is bioequivalent to, or performs in the same manner as, the innovator drug through in vitro, in vivo or other testing. The generic version must deliver the same amount of active ingredients into a subject’s bloodstream in the same amount of time as the innovator drug and can often be substituted by pharmacists under prescriptions written for the reference listed drug. In seeking approval for a drug through an NDA, applicants are required to list with the FDA each patent with claims that cover the applicant’s drug or a method of using the drug. Upon approval of a drug, each of the patents listed in the application for the drug is then published in the Orange Book. Drugs listed in the Orange Book can, in turn, be cited by potential competitors in support of approval of an ANDA or 505(b)(2) NDA.

Upon submission of an ANDA or a 505(b)(2) NDA, an applicant must certify to the FDA that (1) no patent information on the drug product that is the subject of the application has been submitted to the FDA; (2) such patent has expired; (3) the date on which such patent expires; or (4) such patent is invalid or will not be infringed upon by the manufacture, use or sale of the drug product for which the application is submitted. Generally, the ANDA or 505(b)(2) NDA cannot be approved until all listed patents have expired, except where the ANDA or 505(b)(2) NDA applicant challenges a listed patent through the last type of certification, also known as a paragraph IV certification. If the applicant does not challenge the listed patents or indicates that it is not seeking approval of a patented method of use, the ANDA or 505(b)(2) NDA application will not be approved until all of the listed patents claiming the referenced product have expired.

If the ANDA or 505(b)(2) NDA applicant has provided a Paragraph IV certification to the FDA, the applicant must send notice of the Paragraph IV certification to the NDA and patent holders once the application has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the paragraph IV certification. If the paragraph IV certification is challenged by an NDA holder or the patent owner(s) asserts a patent challenge to the paragraph IV certification, the FDA may not approve that application until the earlier of 30 months from the receipt of the notice of the paragraph IV certification, the expiration of the patent, when the infringement case concerning each such patent was favorably decided in the applicant’s favor or settled, or such shorter or longer period as may be ordered by a court. This prohibition is generally referred to as the 30-month stay. In instances where an ANDA or 505(b)(2) NDA applicant files a paragraph IV certification, the NDA holder or patent owner(s) regularly take action to trigger the 30-month stay, recognizing that the related patent litigation may take many months or years to resolve.

The FDA also cannot approve an ANDA or 505(b)(2) application until all applicable non-patent exclusivities listed in the Orange Book for the branded reference drug have expired. For example, a pharmaceutical manufacturer may obtain five years of non-patent exclusivity upon NDA approval of a new chemical entity, or NCE, which is a drug containing an active moiety that has not been approved by FDA in any other NDA. An “active moiety” is defined as the molecule responsible for the drug substance’s physiological or pharmacologic action. During that five-year exclusivity period, the FDA cannot accept for filing (and therefore cannot approve) any ANDA seeking approval of a generic version of that drug or any 505(b)(2) NDA that relies on the FDA’s approval of the drug, provided that that the FDA may accept an ANDA four years into the NCE exclusivity period if the ANDA applicant also files a Paragraph IV certification.

-17-

Table of Contents

A drug, including one approved under Section 505(b)(2), may obtain a three-year period of exclusivity for a particular condition of approval, or change to a marketed product, such as a new formulation for a previously approved product, if one or more new clinical studies (other than bioavailability or bioequivalence studies) was essential to the approval of the application and was conducted/sponsored by the applicant. Should this occur, the FDA would be precluded from approving any ANDA or 505(b)(2) application for the protected modification until after that three-year exclusivity period has run. However, unlike NCE exclusivity, the FDA can accept an application and begin the review process during the exclusivity period.

Other Healthcare Laws and Compliance Requirements

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business. Such laws include, without limitation, state and federal anti-kickback, fraud and abuse, false claims, privacy and security and physician sunshine laws and regulations. If their operations are found to be in violation of any of such laws or any other governmental regulations that apply, they may be subject to penalties, including, without limitation, civil and criminal penalties, damages, fines, the curtailment or restructuring of operations, exclusion from participation in federal and state healthcare programs and individual imprisonment.

Coverage and Reimbursement

Sales of any product depend, in part, on the extent to which such product will be covered by third-party payors, such as federal, state and foreign government healthcare programs, commercial insurance and managed healthcare organizations and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing reimbursements for medical products, drugs and services. In addition, the U.S. government, state legislatures and foreign governments have continued implementing cost-containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit sales of any product. Decreases in third-party reimbursement for any product or a decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product and also have a material adverse effect on sales. Even after the FDA approves a product, failure to have the product covered by third-party payors may have material adverse effect on sales. Federal and state governments continue to promulgate new policies and regulations; such policies and regulations may have material adverse effect on sales. These laws and regulations may restrict, prohibit, or preventing us from implementing a wide range of pricing, discounting, marketing, promotion, sales commission, incentive programs, and other business activities. No uniform policy of coverage and reimbursement among third-party payors exists in the United States. Such payors often rely upon Medicare coverage policy establishing their coverage and reimbursement policies. However, each payor makes independent and separate decisions regarding the extent of coverage and amount of reimbursement to be provided.

Legislative and Regulatory Changes, Including Health Care Reform

The laws and regulations that affect our business are subject to change from time to time, and entirely new laws and regulations are sometimes adopted. In particular, healthcare reforms that have been adopted, and that may be adopted in the future, could result in further reductions in coverage and levels of reimbursement for pharmaceutical products, increases in rebates payable under U.S. government rebate programs and additional downward pressure on pharmaceutical product prices. On September 9, 2021, the Biden administration published a wide-ranging list of policy proposals, most of which would need to be carried out by Congress, to reduce drug prices and drug payment. The Department of Health and Human Services, or HHS, plan includes, among other reform measures, proposals to lower prescription drug prices, including by allowing Medicare to negotiate prices and disincentivizing price increases, and to support market changes that strengthen supply chains, promote biosimilars and generic drugs, and increase price transparency. Many similar proposals, including the plans to give Medicare Part D authority to negotiate drug prices, require drug manufacturers to pay rebates on drugs whose prices increase greater than the rate of inflation, and cap out-of-pocket costs, have already been included in policy statements and legislation currently being considered by Congress. Individual states in the United States have also become increasingly active in implementing regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, proposing to encourage importation from other countries and bulk purchasing. It is unclear to what extent these and other statutory, regulatory, and administrative initiatives will be enacted and implemented.

Foreign Corrupt Practices Act

Our business activities may be subject to the Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA generally prohibits offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to a non-U.S. government official in order to influence official action, or otherwise obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-U.S. governments. Additionally, in many other countries, the health care providers who prescribe pharmaceuticals are employed by their government, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with these prescribers and purchasers are subject to regulation under the FCPA. There is no certainty that all of our employees, agents, suppliers, manufacturers, contractors, or collaborators, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers, or our employees, the closing down of facilities, including those of our suppliers and manufacturers, requirements to obtain export licenses, cessation of business activities in sanctioned countries, implementation of compliance programs, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products in one or more countries as well as difficulties in manufacturing or continuing to develop our products, and could materially damage our reputation, our brand, our international expansion efforts, our ability to attract and retain employees, and our business, prospects, operating results, and financial condition.

European Union Drug Development

In the European Union, our product candidates may also be subject to extensive regulatory requirements. As in the United States, medicinal products can only be marketed if a marketing authorization from the competent regulatory agencies has been obtained.

Similar to the United States, the various phases of preclinical and clinical research in the European Union are subject to significant regulatory controls. Clinical trials of medicinal products in the European Union must be conducted in accordance with European Union, national regulations and international standards for good clinical practice, or GCP.

Clinical trials are currently governed by EU Clinical Trials Directive 2001/20/EC that set out common rules for the control and authorization of clinical trials in the European Union.

To improve the current system, Regulation (EU) No 536/2014 on clinical trials on medicinal products for human use was adopted in 2014. The Regulation aims at harmonizing and streamlining the clinical trials authorization process, simplifying adverse event reporting procedures, improving the supervision of clinical trials, and increasing their transparency, notably via a clinical trial information system set up by the EMA. The new Regulation expressly provides that it will not be applied before six months after the publication of a notice delivered by the European Commission on the European Union clinical trial portal and database. As such notice requires a successful (partial) audit of the database and as that database is still under development, there is no scheduled application date yet. Pursuant to the transitory provisions of the new regulation, the Clinical Trials Directive 2001/20/EC will still apply for three years after the implementation of the European Union clinical trial portal and database. Thus, the sponsor has the possibility to choose between the requirements of the directive and the regulation for a period of three years from the entry into force of the regulation.

European Union Drug Review and Approval

In the EEA (which is comprised of the 28 Member States of the European Union plus Norway, Iceland and Liechtenstein), medicinal products can only be commercialized after obtaining a Marketing Authorization (“MA”). MAs may be granted either centrally (Community MA) or nationally (National MA).

The Community MA is issued centrally by the European Commission through the Centralized Procedure, based on the opinion of the CHMP of the EMA and is valid throughout the entire territory of the EEA. The Centralized Procedure is mandatory for certain types of products such as orphan medicinal products and medicinal products containing a new active substance indicated for the treatment of neurodegenerative disorders. The Centralized Procedure is optional for products containing a new active substance not yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public health in the European Union.

-19-

Table of Contents

National MAs are issued nationally by the competent authorities of the Member States of the EEA and only cover their respective territory. National MAs are available for products not falling within the mandatory scope of the Centralized Procedure. We do not foresee that any of our current product candidates will be suitable for a National MA as they fall within the mandatory criteria for the Centralized Procedure. Therefore, our product candidates will be approved through Community MAs.

Under the above-described procedures, before granting the MA, the EMA or the competent authorities of the Member States of the EEA make an assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy.

The pediatric use marketing authorization, or PUMA, is a dedicated marketing authorization for medicinal products indicated exclusively for use in the pediatric population, with, if necessary, an age-appropriate formulation. Pursuant to Regulation (EC) No. 1901/2006 (The “Pediatric Regulation”), all PUMA applications for marketing authorization for new medicines must include to be valid, in addition to the particulars and documents referred to in Directive 2001/83/EC, the results of all studies performed and details of all information collected in compliance with a pediatric investigation plan agreed between regulatory authorities and the applicant, unless the medicine is exempt because of a deferral or waiver of the EMA.

Before the EMA is able to begin its assessment of a Community MA application, it will validate that the applicant has complied with the agreed pediatric investigation plan. The applicant and the EMA may, where such a step is adequately justified, agree to modify a pediatric investigation plan to assist validation. Modifications are not always possible; may take longer to agree than the period of validation permits; and may still require the applicant to withdraw its marketing authorization application and to conduct additional non-clinical and clinical studies. Products that are granted a MA on the basis of the pediatric clinical trials conducted in accordance with the Pediatric Investigation Plan, or PIP, are eligible for a six-month extension of the protection under a supplementary protection certificate (if any is in effect at the time of approval) or, in the case of orphan medicinal products, a two-year extension of the orphan market exclusivity. This pediatric reward is subject to specific conditions and is not automatically available when data in compliance with the PIP are developed and submitted.

Orphan Drugs

In the European Union, Regulation (EC) No 141/2000 of the European Parliament and of the Council of December 16, 1999 on orphan medicinal products, as amended, states that a drug shall be designated as an orphan drug if its sponsor can establish that the three following cumulative conditions are met:

Pursuant to Regulation (EC) No. 847/2000 of April 27, 2000 laying down the provisions for implementation of the criteria for designation of a medicinal product as an orphan medicinal product and definitions of the concepts “similar medicinal product” and “clinical superiority”, an application for the designation of a drug as an orphan drug must be submitted at any stage of development of the drug before filing of a MA application.

The European Union offers incentives to encourage the development of designated orphan medicines (protocol assistance, fee reductions, etc.) and provides opportunities for market exclusivity. Pursuant to the abovementioned Regulation (EC) No. 141/2000, products receiving orphan designation in the European Union can obtain market exclusivity for a certain number of years in the European Union following the marketing approval.

-20-

Table of Contents

If a Community MA in respect of an orphan drug is granted, regulatory authorities will not, for a period of usually ten years, accept another application for a MA, or grant a MA or accept an application to extend an existing MA, for the same therapeutic indication, in respect of a similar drug. This period may however be reduced to six years if, at the end of the fifth year, it is established, in respect of the drug concerned, that the above-mentioned criteria for orphan drug designation are no longer met, in other words, when it is shown on the basis of available evidence that the product is sufficiently profitable not to justify maintenance of market exclusivity.

Pursuant to Regulation No. 1901/2006, for orphan medicinal products, instead of an extension of the supplementary protection certificate, the ten-year period of orphan market exclusivity should be extended to 12 years if the requirement for data on use in the pediatric population is fully met (i.e. when the request contains the results of all studies carried out under the approved PIP and when the declaration attesting the conformity of the request to this PIP is included in the MA).

Notwithstanding the foregoing, a MA may be granted, for the same therapeutic indication, to a similar drug if:

The abovementioned Regulation (EC) No. 141/2000 provides for other incentives regarding orphan medicinal products.

Post-Approval Controls

The holder of a MA must comply with EU requirements applicable to manufacturing, marketing, promotion and sale of medicinal products. In particular, the holder of the MA must establish and maintain a pharmacovigilance system and appoint an individual qualified person for pharmacovigilance, or QPPV, who is responsible for oversight of that system and who will reside and operate in the EU. Key obligations include safety expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or PSURs.

All new MAs must include a risk management plan, or RMP, to submit to the EMA, describing the risk management system that the company will put in place and documenting measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the MA. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies. RMPs and PSURs are routinely available to third parties requesting access, subject to limited redactions. All advertising and promotional activities for the product must be consistent with the approved summary of product characteristics, and therefore all off-label promotion is prohibited. Direct-to-consumer advertising of prescription medicines is also prohibited in the European Union. Although general requirements for advertising and promotion of medicinal products are established under EU directives, the details are governed by regulations in each EU Member State and can differ from one country to another.

Reimbursement

The European Union provides options for its Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. A Member State may approve a specific price for the medicinal product, or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. For example, in France, effective market access will be supported by agreements with hospitals and products may be reimbursed by the Social Security Fund. The price of medicines covered by national health insurance is negotiated with the Economic Committee for Health Products, or CEPS. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our product candidates. Historically, products launched in the European Union do not follow price structures of the United States and generally prices tend to be significantly lower.

Other European Regulatory Matters

French Regulatory Framework for Clinical Development

In France, Directive No. 2001/20/EC has been implemented in French national law, establishing a system of prior authorization and requiring a prior favorable opinion from an ethics committee.

Parties to a clinical trial agreement, or CTA, must use a CTA template (“unique agreement” or “convention unique”) to organize the conduct of interventional clinical trials with commercial purpose, as well as specific template exhibits to this agreement. Once concluded, the CTA is communicated for information by the sponsor to the French national board of physicians (Ordre national des médecins) without delay.

The processing of personal data collected during clinical trials has to comply with the Regulation (EU) 2016/679 of the European Parliament and of the Council of April 27, 2016 and Law No 2018-493 of June 20, 2018 on the protection of personal data, implementing the Regulation (EU) 2016/679 requirements. Regarding automatic processing operations for the purpose of research or clinical studies, formalities have to be completed before the French data protection authority, the Commission Nationale de l’Informatique et des Libertés, or CNIL, so as to obtain the authorization to process personal data. However, there are simplified standards.

Law No. 2011-2012 of December 29, 2011, or Loi Bertrand, aimed at strengthening the health safety of medicinal and health products, as amended (and its implementing decrees), introduced into French law provisions regarding transparency of fees received by some healthcare professionals from health product industries, i.e. companies manufacturing or marketing health products (Article L.1453-1 of the French Public Health Code). These provisions have been recently extended and redefined by Decree No. 2016-1939 of December 28, 2016, which clarified French “Sunshine” regulations. The decree notably provides that companies manufacturing or marketing health care products (medicinal products, medical devices, etc.) in France shall publicly disclose (mainly on a specific public website available at: https://www.entreprises-transparence.sante.gouv.fr) the advantages and fees paid to healthcare professionals amounting to €10 or above, as well as the agreements concluded with the latter, along with detailed information about each agreement (the precise subject matter of the agreement, the date of signature of the agreement, its end date, the total amount paid to the healthcare professional, etc.). Another declaration must also be filed to the competent healthcare professional body. Law No. 2011-2012 also reinforced the French anti-gift rules and Order No. 2017-49 of January 19, 2017 amended the law and expanded the scope of the general prohibition of payments from pharmaceutical and device manufacturers to healthcare professionals to broadly cover any company manufacturing or marketing health products, regardless of whether or not payment for the products is reimbursed under the French social security system (new Articles L. 1453-3 et seq. of the French Public Health Code). It also changed the procedure related to the prior submission to the national or departmental board of the relevant healthcare professional body. Moreover, the penalties incurred for non-compliance with the requirements of the Anti-Gift Law will be doubled to a fine of up to €750,000. The changes of the anti-gift rules will only enter into force after the publication of implementing measures.

Environmental Matters

Our operations, properties and products are subject to a variety of U.S. and foreign environmental laws and regulations governing, among other things, air emissions, wastewater discharges, management and disposal of hazardous and non-hazardous materials and waste and remediation of releases of hazardous materials. We believe, based on current information, that we are in material compliance with environmental laws and regulations applicable to us. However, our failure to comply with present and future requirements under these laws and regulations, or environmental contamination or releases of hazardous materials on our leased premises, as well as through disposal of our products, could cause us to incur substantial costs, including clean-up costs, personal injury and property damage claims, fines and penalties, costs to redesign our products or upgrade our facilities and legal costs, or require us to curtail our operations, any of which could seriously harm our business.

We are subject to various risks that could have a material adverse effect on our business, our financial condition and our results of operations. These risks could cause actual operating results to differ from those expressed in certain “forward looking statements” contained in this Annual Report as well as in other communications.

Summary of Risk Factors

● We do not expect to consummate certain previously disclosed transactions.

● We will face intense competition and may not be able to compete successfully.

We have never paid and do not intend to pay cash dividends on our Common Stock. As a result, capital appreciation, if any, will be your sole source of gain.

Risks Related to Our Business, Financial Position and Capital Requirements

Our current dependency on external funding for our operations raises a substantial doubt about our ability to continue as a going concern. If we do not continue as a going concern, investors could lose their entire investment.

The accompanying consolidated financial statements have been prepared as if we will continue as a going concern. We have incurred significant operating losses and negative cash flows from operations since inception. On December 31, 2024, we had cash and cash equivalents of approximately $0.2 million, and an accumulated deficit of approximately $202.4 million. We have incurred recurring losses, have experienced recurring negative operating cash flows, and require significant cash resources to execute our business plans. Subsequent to December 31, 2024, we closed on a revolving loan agreement in the principal amount of $2.0 million. Based on cash on hand at December 31, 2024 and the available loan proceeds and assuming successful financing efforts, which we cannot guarantee, we anticipate having sufficient cash to fund planned operations through September 2025. Historically, our major sources of cash have been comprised of proceeds from various public and private offerings of its capital stock. We are dependent on obtaining additional working capital funding from the sale of equity and/or debt securities in order to continue to execute our development plans and continue operations.

We have been, and are expected to continue, exploring various potential strategies available including but not limited to raising capital, restructuring our indebtedness and identifying and evaluating potential strategic alternatives but there can be no assurance that these efforts will be successful, that the Company will be able to raise necessary capital on acceptable terms, reach agreement with lenders, or that the strategic review process will result in the Company pursuing any transaction or that any transaction, if pursued, will be completed on attractive terms or at all. We are evaluating all potential strategic options, including a merger, reverse merger, sale, wind-down, liquidation and dissolution or other strategic transaction. Additionally, there can be no assurances that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated or lead to increased stakeholder value or that it will make any cash distributions to stockholders. Any failure in these efforts could force us to delay, limit or

-24-

Table of Contents

terminate operations, make reductions in our workforce, discontinue research and development programs, liquidate all or a portion of assets or pursue other strategic alternatives, and/or seek protection under the provisions of the U.S. Bankruptcy Code.

Without adequate working capital, we may not be able to meet our obligations and continue as a going concern. These conditions raise substantial doubt about our ability to continue as a going concern one year from the date these financial statements are issued. If the Company is not able to obtain necessary capital, we may be required to terminate operations, liquidate all or a portion of assets and/or seek bankruptcy protection. As a result, we have concluded that our plans at this stage do not alleviate substantial doubt about the ability to continue as a going concern. Our financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Our level of indebtedness and our ability to make payments on or service our indebtedness could adversely affect our business, financial condition, results of operations, cash flow and liquidity.

Effective January 31, 2025, we entered into the Revolving Loan Agreement. Pursuant to and under the terms of the Revolving Loan Agreement, we issued to the Lender a revolving note dated January 27, 2025 in the principal amount of $2,000,000. Out of the principal amount, the Lender disbursed an initial loan amount of $550,000 to the Company on January 31, 2025.

The Revolving Note bears interest at the rate of 18% per annum calculated on the basis of a 360-day year, consisting of twelve 30 calendar day periods, and shall accrue daily commencing on January 31, 2025 until paid in full. The outstanding principal balance, all accrued and unpaid interest and all other amounts, costs, expenses and/or liquidated damages are due in full on January 31, 2026. The Revolving Loan Agreement contains customary events of default. If an event of default occurs, the Lender may accelerate the indebtedness under the Revolving Loan Agreement, and an amount equal to 120% of the of the outstanding principal amount and accrued and unpaid interest plus liquidated damages and other amounts, costs, expenses and/or liquidated damages due.

If we are not able to repay or refinance our debt as it becomes due, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt or equity on terms that may be onerous or highly dilutive, if we can obtain it at all. If we raise equity through the issuance of preferred stock, the terms of the preferred stock may give the holders rights, preferences and privileges senior to those of holders of our Common Stock, particularly in the event of liquidation. Our ability to arrange financing or refinancing will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and other factors beyond our control. We cannot assure you that we will be able to obtain financing or refinancing on terms acceptable to us or at all.

If funds are not available when needed, or available on acceptable terms, we may be required to delay, scale back or eliminate some of our obligations. In addition, we may not be able to grow market share, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, which could negatively impact our business, operating results and financial condition.

We will require substantial additional financing to achieve our goals, and a failure to obtain this necessary capital when needed and on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our product candidate development programs, testing efforts or other operations, including.

We expect our expenses to increase in connection with our ongoing activities. We also expect to incur significant expenses related to the development, testing, and manufacturing of our product candidates. We cannot reasonably estimate the actual amounts necessary to successfully complete the development and commercialization of our products. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any potential future commercialization efforts.

We have based our estimates on assumptions that may prove to be wrong, and we could use our capital resources sooner than we currently expect. Our operating plans and other demands on our cash resources may change as a result of many factors, including costs required to advance Adrulipase, as well as factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings or other capital sources, including potentially government funding, collaborations, licenses and other similar arrangements. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. Attempting to secure

additional financing may divert our management from its day-to-day activities, which may adversely affect our ability to develop our product candidates.

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

● the costs and timing of manufacturing for our product candidates;

Additional offerings in the future may dilute then existing stockholders’ percentage ownership of our Company.

Given our plans and expectations that we will need additional capital, in the near future we may need to issue additional Common Stock or securities convertible or exercisable for Common Stock, including convertible preferred shares, convertible notes, stock options or warrants. The issuance of additional securities in the future will dilute the percentage ownership of then existing stockholders. Additionally, sales by existing stockholders of a large number of our Common Stock in the public market could also affect the market price of our Common Stock.

We do not expect to consummate certain previously disclosed proposed transactions.

On December 27, 2023, we announced that we entered a non-binding term sheet to sell our Niclosamide program. This transaction is not expected to move forward. Development on the Niclosamide program is currently on hold due to capital constraints and we will continue to explore options to out license or sell this program. There can be no assurance that any such out-licenses or sales will be consummated on terms favorable to us or at all. Additionally, if we fail to consummate such out-licenses or sales, such failure could result in fluctuations to the market price of our Common Stock and may have a material adverse impact on our financial condition and results of operations.

If we do not consummate the transactions contemplated by the Rescission Agreement, we will remain responsible for approximately $9,278,400 of secured debt, and our level of indebtedness and our ability to make payments on or service our indebtedness could adversely affect our ability to implement our business plan as currently contemplated, and also adversely affect our financial condition, results of operations, cash flow and liquidity. Defaults under this debt could result in a substantial loss of our assets. We may also be required to settle conversion of our Series G Preferred Stock in cash.

The Company expects that the closing of the Rescission Agreement will occur on or prior to June 30, 2025, subject to satisfaction of all conditions for closing, including obtaining shareholder approval by the Company for the transfer of the Membership Interests to the Shareholders. We cannot guarantee that the closing will occur by June 30, 2025 or at all. If the transactions contemplated by the Rescission Agreement are not consummated, we will remain responsible for an aggregate of approximately $9,278,400 of secured debt owed to Mattress Liquidators, Inc., our director Jack Syage, and to Peter Felker. If we are not able to repay or refinance our debt as it becomes due, we will not be able to implement our business plan as currently contemplated and may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional debt or equity on terms that may be onerous or highly dilutive, if we can obtain it at all. If we raise equity through the issuance of preferred stock, the terms of the preferred stock may give the holders rights, preferences and privileges senior to those of holders of our Common Stock, particularly in the event of liquidation. Our ability to arrange financing or refinancing will depend on, among other factors, our financial position and performance, as well as prevailing market conditions and other factors beyond our control. We cannot assure you that we will be able to obtain financing or refinancing on terms acceptable to us or at all. If funds are not available when needed, or available on acceptable terms, we may be required to delay, scale back or eliminate some of our obligations. In addition, we may not be able to grow market share, take advantage of future opportunities or respond to competitive pressures or unanticipated requirements, which could negatively impact our business, operating results and financial condition.

These borrowings are secured by substantially all of the assets of IMGX and the patents and trademarks owned by IMGX. If an event of default under any of such agreements could enable the lenders or creditors thereunder to declare all borrowings outstanding on such debt, together with accrued and unpaid interest and fees, to be due and payable. The lenders could also elect to foreclose on our assets securing such debt. In such an event, the Company may not be able to refinance or repay all of its indebtedness, have sufficient liquidity to meet operating and capital expenditure requirements, or hold the necessary intellectual property rights to conduct its business. Any such acceleration could cause us to lose a substantial portion of our assets and will substantially adversely affect our ability to continue our operations.

Further, if the transactions contemplated by the Recission Agreement are not consummated, 11,777.418 shares of our Series G Preferred Stock will remain outstanding. The holders of our outstanding shares of Series G Preferred Stock are entitled to elect to have such shares of Series G Preferred Stock redeemed for cash at a price per share equal to the then-current fair value of the Series G Preferred Stock, as described in the Certificate of Designation of Preferences, Rights and Limitations of the Series G Non-Voting Preferred Stock. Unless we operate profitably, our ability to redeem the Series G Preferred Stock would require the availability of adequate “surplus,” which is defined as the excess, if any, of our net assets (total assets less total liabilities) over our capital. If we do have sufficient “surplus” to effect any requested redemption of the Series G Preferred Stock, our available cash will be negatively impacted. In addition, such reduction in our available cash could decrease the trading price of our Common Stock.

We are a clinical stage biopharmaceutical company and have a limited operating history upon which to base an investment decision.

We are a clinical stage biopharmaceutical company. Since inception, we have engaged primarily in research and development activities of Adrulipase and Niclosamide, and more recently Latiglutenase and Capeserod. We have not generated any revenue from product sales and have incurred significant net losses. We have not demonstrated our ability to perform the functions necessary for the successful commercialization of any product candidates. The successful commercialization of any of our products will require us to perform a variety of functions, including:

● continuing to undertake pre-clinical development and clinical trials;

● participating in regulatory approval processes;

● formulating and manufacturing products; and

● conducting sales and marketing activities.

Our operations to date have been limited to organizing and staffing, acquiring, developing and securing the proprietary rights for, and undertaking pre-clinical development, manufacturing and clinical trials of Adrulipase, Niclosamide, Capeserod and Latiglutenase. These operations provide a limited basis for our stockholders and prospective investors to assess our ability to complete development of or commercialize Adrulipase or any other product candidates and the advisability of investing in our securities.

We have incurred significant losses and negative cash flows from our operations since inception. As of December 31, 2024, we had accumulated deficit of approximately $202.4 million and negative working capital of approximately $4.3 million. Based on our historical and anticipated rate of cash expenditures, we do not anticipate our existing working capital will be sufficient to sustain our business through the commercialization of our product candidates. Therefore, we are dependent on obtaining, and are continuing to pursue, the necessary funding from outside sources, including obtaining additional funding from the sale of securities in order to continue our operations. We are actively working to obtain additional funding. We cannot make any assurances that additional financings will be available to us and, if available, completed on a timely basis, on acceptable terms or at all. If we are unable to complete an equity and/or debt offering, or otherwise obtain sufficient financing when and if needed, it would negatively impact our business and operations, which would likely cause the price of our Common Stock to decline or ultimately force us to cease our operations.

We will face intense competition and may not be able to compete successfully.

We operate in highly competitive segments of the biotechnology and biopharmaceutical markets. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Adrulipase, if successfully developed and approved, will compete with established therapies, as well as new treatments that may be introduced by our competitors. Many of our competitors have significantly greater financial, product development, manufacturing and marketing resources than us. Large pharmaceutical companies have extensive experience in clinical testing and obtaining regulatory approval for drugs. We also may compete with these organizations to recruit management, scientists and clinical development personnel. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. New developments, including the development of other biological and pharmaceutical technologies and methods of treating disease, occur in the pharmaceutical and life sciences industries at a rapid pace. Developments by competitors may render our product candidates obsolete or noncompetitive. We will also face competition from these third parties in recruiting and retaining qualified personnel, establishing clinical trial sites and patient registration for clinical trials and in identifying and in-licensing new product candidates.

We may incur substantial product liability or indemnification claims relating to the use of our product candidates.

We face an inherent risk of product liability exposure based on the use of Adrulipase in human clinical trials, or, if obtained, following marketing approval and commercialization. Claims could be brought against us if use or misuse of one of our product candidates causes, or merely appears to have caused, personal injury or death. Although we have and intend to maintain product liability insurance relating to our clinical trials, our coverage may not be sufficient to cover claims that may be made against us and we may be unable to maintain such insurance. Any claims against us, regardless of their merit, could severely harm our financial condition, strain our management and other resources or destroy the prospects for commercialization of the product which is the subject of any such claim. We are unable to predict if we will be able to obtain or maintain product liability insurance for any products that may be approved for marketing. Additionally, we have entered into various agreements where we indemnify third parties for certain claims relating to the testing and use of our product candidates. These indemnification obligations may require us to pay significant sums of money for claims that are covered by these indemnifications.

We cannot predict all of the possible harms or side effects that may result from the use of our products and, therefore, the amount of insurance coverage we currently hold, or that we or our collaborators may obtain, may not be adequate to protect us from any claims arising from the use of our products that are beyond the limit of our insurance coverage. If we cannot protect against potential liability claims, we or our collaborators may find it difficult or impossible to commercialize our products, and we may not be able to renew or increase our insurance coverage on reasonable terms, if at all. The marketing, sale and use of our products and our planned future products could lead to the filing of product liability claims against us if someone alleges that our products failed to perform as designed. A product liability or professional liability claim could result in substantial damages and be costly and time-consuming for us to defend.

Any product liability or professional liability claim brought against us, with or without merit, could increase our insurance rates or prevent us from securing insurance coverage. Additionally, any product liability lawsuit could damage our reputation, result in the recall of products, or cause current partners to terminate existing agreements and potential partners to seek other partners, any of which could impact our results of operations.

We use biological materials and may use hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time consuming or costly.

We may use hazardous materials, including chemicals and biological agents and compounds, that could be dangerous to human health and safety or the environment. Our operations also produce hazardous waste products. Federal, state and local laws and regulations govern the use, generation, manufacture, storage, handling and disposal of these materials and wastes. Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may impair our product development efforts. In addition, we cannot entirely eliminate the risk of accidental injury or contamination from these materials or wastes. We do not carry specific biological or hazardous waste insurance coverage and our property and casualty, and general liability insurance policies specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination. Accordingly, in the event of contamination or injury, we could be held liable for damages or penalized with fines in an amount exceeding our resources, and our clinical trials or regulatory approvals could be suspended.

Table of Contents

Although we maintain workers’ compensation insurance to cover us for costs and expenses, we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of December 31, 2024, we had 2 full-time employees. As our development and commercialization plans and strategies develop, we expect to need additional managerial, operational, research and development, sales, marketing, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

Our future financial performance and our ability to commercialize our product candidates will depend, in part, on our ability to effectively manage any future growth, and our management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants to provide certain services, including certain aspects of regulatory approval, clinical management and manufacturing. There can be no assurance that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants and contractors or find other competent outside contractors and consultants on economically reasonable terms, or at all.

If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may not be able to successfully implement the tasks necessary to further develop and commercialize our product candidates and, accordingly, may not achieve our research, development and commercialization goals.

Disruptions in the global economy and supply chains may have a material adverse effect on our business, financial condition and results of operations.

The disruptions to the global economy in 2020 and into 2024 have impeded global supply chains, resulting in longer lead times and also increased critical component costs and freight expenses. We have taken and may have to take steps to minimize the impact of these disruptions in lead times and increased costs by working closely with our suppliers and other third parties on whom we rely for the conduct of our business. Despite the actions we have undertaken or may have to undertake to minimize the impacts from disruptions to the global economy, there can be no assurances that unforeseen future events in the global supply chain will not have a material adverse effect on our business, financial condition and results of operations.

Furthermore, inflation can adversely affect us by increasing the costs of clinical trials, the research and development of our product candidates, as well as administration and other costs of doing business. We may experience increases in the prices of labor and other costs of doing business. In an inflationary environment, cost increases may outpace our expectations, causing us to use our cash and other liquid assets faster than forecasted. If this happens, we may need to raise additional capital to fund our operations, which may not be available in sufficient amounts or on reasonable terms, if at all, sooner than expected.

Adverse global conditions, including economic uncertainty, may negatively impact our financial results.

Global conditions, dislocations in the financial markets, any negative financial impacts affecting United States as a result of tax reform or changes to existing trade agreements or tax conventions, may adversely impact our business.

In addition, the global macroeconomic environment could be negatively affected by, among other things, pandemics or epidemics, instability in global economic markets, increased U.S. trade tariffs and trade disputes with other countries, instability in the global credit markets, supply chain weaknesses, instability in the geopolitical environment as a result of the Russian invasion of Ukraine, the war between Israel and Hamas and other political tensions, and foreign governmental debt concerns. Such challenges have caused, and may continue to cause, uncertainty and instability in local economies and in global financial markets.

Geopolitical risks associated with Russia’s invasion of Ukraine and Israel’s war with Hamas could result in increased market volatility and uncertainty, which could negatively impact our business, financial condition, and results of operations.

The uncertain nature, scope, magnitude, and duration of hostilities stemming from Russia’s military invasion of Ukraine and Israel’s war with Hamas, including the potential effects of such hostilities as well as sanctions, embargoes, asset freezes, cyber-attacks and other actions taken in response to such hostilities on the world economy and markets, have disrupted global markets and contributed to increased market volatility and uncertainty, which could have an adverse impact on macroeconomic and other factors that affect our business and supply chain. There can be no certainty regarding the impacts stemming from the invasion, including the imposition of additional sanctions, embargoes, asset freezes or other economic or military measures resulting from the invasion. The impact of these developments, and additional events that may occur as a result, is currently unknown and could adversely affect our business, supply chain, suppliers and customers and potential customers. It is not possible to predict the broader consequences of this conflict, which could include further sanctions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, the availability and cost of materials, supplies, labor, currency exchange rates and financial markets, all of which could negatively impact our business, financial condition and results of operations.

Significant disruptions of information technology systems or breaches of data security could materially adversely affect our business, results of operations and financial condition.

We collect and maintain information in digital form that is necessary to conduct our business, and we are increasingly dependent on information technology systems and infrastructure to operate our business. In the ordinary course of our business, we collect, store and transmit large amounts of confidential information, including intellectual property, proprietary business information and personal information. It is critical that we do so in a secure manner to maintain the confidentiality and integrity of such confidential information. We have established physical, electronic and organizational measures to safeguard and secure our systems to prevent a data compromise, and rely on commercially available systems, software, tools, and monitoring to provide security for our information technology systems and the processing, transmission and storage of digital information. We have also outsourced elements of our information technology infrastructure, and as a result a number of third-party vendors may or could have access to our confidential information. Our internal information technology systems and infrastructure, and those of our current and any future collaborators, contractors and consultants and other third parties on which we rely, are vulnerable to damage from computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over the Internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization.

The risk of a security breach or disruption, particularly through cyber-attacks or cyber-intrusion, including by computer hackers, foreign governments and cyber-terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. In addition, the prevalent use of mobile devices that access confidential information increases the risk of data security breaches, which could lead to the loss of confidential information or other intellectual property. The costs to us to mitigate network security problems, bugs, viruses, worms, malicious software programs and security vulnerabilities could be significant, and while we have implemented security measures to protect our data security and information technology systems, our efforts to address these problems may not be successful, and these problems could result in unexpected interruptions, delays, cessation of service and other harm to our business and our competitive position. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product development programs. For example, the loss of clinical trial data from completed or ongoing or planned clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Moreover, if a computer security breach affects our systems or results in the unauthorized release of personally identifiable information, our reputation could be materially damaged.

In addition, such a breach may require notification to governmental agencies, the media or individuals pursuant to various federal and state privacy and security laws, if applicable, including the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Clinical Health Act of 2009, and its implementing rules and regulations, as well as regulations promulgated by the Federal Trade Commission and state breach notification laws.

Under the EU regulation and notably the General Data Protection Regulation, or GDPR, No. 2016/679, which entered into force on May 25, 2018 and is applicable personal data that we process in relation to our presence in the EU, the offering of products or services to individuals in the EU or the monitoring of the behavior of individuals in the EU, we have also a legal responsibility to report personal data breaches to the competent supervisory authority. The EU data protection regulation includes a broad definition and a short deadline for the notification of personal data breaches, which may be difficult to implement in practice and requires that we implement robust internal processes. Under this regulation, we have to report personal data breaches to the competent supervisory authority within 72 hours of the time we become aware of a breach “unless the personal data breach is unlikely to result in a risk to the right and freedoms of natural persons” (Article 33 of the GDPR). In addition, the GDPR requires that we communicate the breach to the Data Subject if the breach is “likely to result in a high risk to the rights and freedoms of natural persons” (Article 34 of the GDPR). In order to fulfil these requirements, we have to implement specific internal processes to be followed in case of a personal data breach, which will allow us to (a) contain and recover the breach, (b) assess the risk to the data subjects, (c) notify, and possibly communicate the breach to the data subjects, (d) investigate and respond to the breach. The performance of these processes implies substantial costs in resources and time.

Moreover, as we may rely on third parties that will also process as processor the data for which we are a data controller—for example, in the context of the manufacturing of our product candidates or for the conduct of clinical trials, we must contractually ensure that strict security measures, as well as appropriate obligations including an obligation to report in due delay any security incident are implemented, in order to allow us fulfilling our own regulatory requirements.

We would also be exposed to a risk of loss or litigation and potential liability for any security breach on personal data for which we are data controller. The costs of above-mentioned processes together with legal penalties, possible compensation for damages and any resulting lawsuits arising from a breach may be extensive and may have a negative impact on reputation and materially adversely affect our business, results of operations and financial condition.

Requirements associated with being a public company will increase our costs significantly and will divert significant company resources and management attention.
