SUBJECT TO COMPLETION, DATED JANUARY 12, 2023

PRELIMINARY PROSPECTUS

[●] UNITS CONSISTING OF COMMON STOCK,

OR PRE-FUNDED WARRANTS TO PURCHASE SHARES OF COMMON STOCK,

AND WARRANTS TO PURCHASE SHARES OF COMMON STOCK

We are offering up to [●] units, each consisting of one share of our common stock, par value $0.001 per share, and one warrant to purchase one and one-half shares of common stock, in a firm commitment underwritten public offering at an assumed offering price of $7.53 per unit, which is equal to the closing price of our common stock on the Nasdaq Capital Market on January 5, 2023, for gross proceeds of approximately $8.5 million. Each common warrant will have an exercise price of $[●] per share of common stock (equal to 100% of the public offering price of each unit sold in this offering), will be exercisable immediately, and will expire five years from the date of issuance.

We are also offering to each purchaser of units that would otherwise result in the purchaser’s beneficial ownership exceeding 4.99% of our outstanding common stock immediately following the consummation of this offering the opportunity to purchase units consisting of one pre-funded warrant (in lieu of one share of common stock) and one common warrant. A holder of pre-funded warrants will not have the right to exercise any portion of its pre-funded warrants if the holder, together with its affiliates, would beneficially own in excess of 4.99% (or, at the election of the holder, such limit may be increased to up to 9.99%) of the number of shares of common stock outstanding immediately after giving effect to such exercise. Each pre-funded warrant will be exercisable for one share of common stock. The purchase price of each unit including a pre-funded warrant will be equal to the price per unit including one share of common stock, minus $0.0001, and the remaining exercise price of each pre-funded warrant will equal $0.0001 per share. The pre-funded warrants will be immediately exercisable (subject to the beneficial ownership cap) and may be exercised at any time until all of the pre-funded warrants are exercised in full. For each unit including a pre-funded warrant we sell (without regard to any limitation on exercise set forth therein), the number of units including a share of common stock we are offering will be decreased on a one-for-one basis.

The shares of our common stock and pre-funded warrants, if any, and the accompanying common warrants can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance. We are also registering the shares of common stock issuable from time to time upon exercise of the common warrants and pre-funded warrants included in the units offered hereby.

Our common stock is traded on the Nasdaq Capital Market under the symbol “RSLS.” On January 5, 2023, the closing price for our common stock, as reported on the Nasdaq Capital Market, was $7.53 per share. The public offering price per unit will be determined at the time of pricing and may be at a discount to the then current market price. The recent market price used throughout this prospectus may not be indicative of the final offering price. The final public offering price will be determined through negotiation between us and investors based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering.

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

PROSPECTUS SUMMARY

This summary highlights certain information about us, this offering and selected information contained in this prospectus. This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in our securities. For a more complete understanding of our company and this offering, we encourage you to read and consider the more detailed information included in this prospectus, including risk factors, see “Risk Factors” beginning on page 7 of this prospectus, and our most recent consolidated financial statements and related notes.

Throughout this prospectus, the terms “we,” “us,” “our,” “ReShape,” and “our company” refer to ReShape LifeSciences Inc., a Delaware corporation, and its consolidated subsidiaries, unless the context requires otherwise.

About ReShape Lifesciences Inc.

ReShape Lifesciences Inc. is a worldwide premier weight-loss solutions company, offering an integrated portfolio of proven products and services that manage and treat obesity and metabolic disease throughout the care continuum.

Our current portfolio includes the FDA-approved and reimbursed Lap-Band® system, which provides minimally invasive, long-term treatment of obesity and is a safer surgical alternative to more invasive and extreme surgical stapling procedures such as the gastric bypass or sleeve gastrectomy. Our ReShapeCare^TM virtual health coaching program is a novel weight-management program that supports healthy lifestyle changes for all medically managed weight-loss patients, not just individuals who qualify for Lap-Band surgery, further expanding our reach and market opportunity. Our ReShape Marketplace^TM online store provides top of the line products with bariatric patients in mind. Our ReShape Optimize^TM supplement options, purchased through the ReShape Marketplace, include multivitamins, probiotics, calcium, vitamin D, protein, and other therapeutic offerings to optimize health.

In August of 2022, the Board of Directors of the Company appointed Paul F. Hickey as President and Chief Executive Officer. Under this new leadership, the Company has pivoted its business strategy with the intent of helping ensure a path of growth and profitability. The three growth strategies, or pillars for growth that the Company intends to execute are:

This first growth pillar is, in the Company’s opinion, paramount for ReShape in order to deliver shareholder value and, ultimately, profitability. Since shortly after Mr. Hickey’s appointment, ReShape has made a number of operational changes to help ensure future performance and return on investment by prioritizing investments supporting revenue growth. As an example, the Company moved towards a highly targeted, direct-to-consumer marketing campaign to help yield both higher

quality and lower cost patient leads in specific markets that align with surgeon advocates. As a result, lead cost in the third and fourth quarters of 2022 dropped over 50% as compared to the second quarter of 2022. The company has also taken steps to right-size the organization in several areas to ensure sustainability and scalability.

In executing the first growth pillar, the Company will continue to focus on revenue growth and profitability. Once the Company completes this offering, it believes it will have sufficient cash on hand to execute on its goal of becoming profitable within the next 18 months. This estimated timeline could be compressed or extended depending on many factors, including revenue growth from new product introductions, or strategic investments not yet foreseen.

ReShape’s second growth pillar is intended to further differentiate the Company as a leading provider of innovative products and services to meet unmet customer needs. ReShape is committed to drive and scale its new product development and commercialization capacity, providing a cadence to new product introductions and revenue growth.

Management anticipates that new product revenue in 2023 will include both ReShape Calibration Tube line extensions and ReShapeCare. The ReShape Calibration Tube is utilized in the majority of bariatric surgeries performed today and provides a cross-selling opportunity with access to accounts that may not be utilizing Lap-Band.

ReShapeCare could have revenue opportunities with employees of large, self-insured employers, with potential Lap-Band patient pre- and post-surgical support, as well as individuals who may not need physician-led weight loss management.

Potential new product revenues beyond 2023 include the Lap-Band 2.0, which is anticipated to be filed with the FDA in the first half of 2023 with feedback from the FDA expected by 2023 year-end. The Lap-Band 2.0 is designed to reduce the required postoperative physician office-based Lap-Band adjustments.

The ReShape Obalon® Balloon system is the first and only swallowable, gas filled, FDA-approved balloon system. In 2023 the Company plans on further evaluating OEM partnerships and distribution partnerships that would be intended to support the successful relaunch and commercialization of the balloon system.

ReShape remains committed to furthering our proprietary Diabetes Bloc-Stim Neuromodulation (DBSN) technology that can potentially eliminate the need for medications by those with type 2 diabetes. The DBSN device is a technology under development as a new treatment for type 2 diabetes mellitus. The device is expected to use bioelectronics to manage blood glucose in treatment of diabetes and individualized 24/7 glucose control. The DBSN technology development has received nondilutive NIH grant support.

Recent statements from the bariatric surgeon societies in the U.S. and abroad including the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO), confirm that obesity is a complex disease that requires personalized treatment to ensure long-term weight loss goals are achieved. ReShape’s third growth pillar represents the Company’s commitment to collaborate with healthcare professionals worldwide and further develop evidence supporting ReShape’s portfolio of treatment options.

ReShape intends to establish and work closely with its first-ever global Scientific Advisory Board (SAB) to provide needed expertise and feedback on initiatives related to the Company’s growth pillars. The SAB will include surgeons from the U.S. and abroad who have expertise and perspective necessary to validate the Company’s direction and priorities. It is anticipated the SAB will be formed in early 2023.

Our Product Portfolio

Lap-Band System

The Lap-Band System is designed to provide minimally invasive long-term treatment of severe obesity and is an alternative to more invasive surgical stapling procedures such as the gastric bypass or sleeve gastrectomy. Unlike other invasive anatomy altering procedures, the Lap-Band System is adjustable post-operatively via a saline-filled silicone band that is laparoscopically placed around

the upper part of the stomach through a small incision, creating a small pouch at the top of the stomach, which slows the passage of food and creates a sensation of fullness. The procedure can normally be performed as an outpatient procedure and patients can go home the day of the procedure without the need for an overnight hospital stay.

ReShape Calibration Tubes

The ReShape Calibration tubes are multifunctional devices compared to reusable bougies and disposable gastric tubes. The Calibration tubes are designed to be less traumatic to the patient, as they are intended to fit the lesser curvature of the stomach more easily and quickly reach the pylorus. In August of 2022, we announced FDA clearance of three new sizes – 32, 36, and 40 French – all designed to simplify bariatric procedures such as laparoscopic sleeve gastrectomy, gastric bypass, and adjustable gastric banding. We are ramping up production and moving rapidly towards a full release of this product in early 2023.

ReShapeCare

ReShapeCare is a HIPAA-compliant, virtual coaching program that enhances behavior change through engagement with ReShape’s Welcome Specialists and Health Coaches. The ReShapeCare program is based on four established dimensions of successful behavior: change sleep, nutrition, exercise and stress. It is designed to provide flexible structure and support from a live ReShapeCare certified health coach in a manner that is simple, affordable and practical.

ReShape Marketplace

ReShape Marketplace is an online store developed with bariatric patients in mind in order to focus on the four dimensions of successful behavior changes. Within the ReShape Marketplace, we have ReShape Optimize, which meets all the nutrient needs to stay healthy. The ReShape Marketplace provides the highest quality products for exercising, that can have immediate and long-term health benefits, sleep which plays a vital role in good health and well-being, and stress to effectively manage stress to make your life happier, healthier and more productive.

Lap-Band 2.0 System

The Lap-Band 2.0, like the original Lap-Band System, is designed to provide minimally invasive long-term treatment of severe obesity and is an alternative to more invasive surgical stapling procedures such as the gastric bypass or sleeve gastrectomy. Unlike more invasive and anatomy altering surgeries, the Lap-Band 2.0 is adjustable postoperatively to increase or decrease the pressure to the band in order to optimize an individual’s comfort and therapy effectiveness. The Lap-Band 2.0 system includes a reservoir technology designed to minimize postoperative in-office patient band adjustments, thereby potentially improving an individual’s tolerance for the Lap-Band 2.0.

ReShape Obalon Balloon System

The Obalon Balloon System consists of a swallowable capsule that contains an inflatable balloon attached to a microcatheter; the Obalon Navigation System console, which is a combination of hardware and software used to dynamically track and display the location of the balloon during placement; the Obalon Touch Inflation Dispenser, which is a semi-automated, hand-held inflation device used to inflate the balloon once it is placed; and a disposable canister filled with our proprietary mixture of gas. We continue to explore the compliance requirements, manufacturing viability and quality system controls necessary for re-introducing the Obalon Balloon System.

DBSN Device

The DBSN device is a technology under development as a new treatment for type 2 diabetes mellitus (T2DM). It combines ReShape Lifesciences’ proprietary Vagus Nerve Block (vBloc) technology platform in combination with Vagus nerve stimulation. This new dual Vagus nerve neuromodulation device selectively modulates vagal block and stimulation to the liver and pancreas to manage blood glucose. Our DBSN device is expected to use bioelectronics to manage blood glucose in treatment of diabetes and individualized 24/7 glucose control. The goal is to reduce costs of treatment and complications that arise from poorly controlled blood glucose and non-compliance to T2DM medication.

Recent Developments

On July 19, 2022, we received a written notice from The Nasdaq Stock Market indicating that we were not in compliance with the $1.00 minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market. The notice provided that we have until January 16, 2023 to regain compliance. If at any time during this period the closing bid price of our common stock is at least $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will provide us with a written confirmation of compliance and the matter will be closed. In order to regain compliance with the bid price requirement, we effected a 1-for-50 reverse stock split of our issued and outstanding common stock on December 23, 2022. Following the reverse stock split, the closing bid price of our common stock has been at least $1.00 for at least 10 consecutive business days as of the date of this prospectus. Therefore, we expect Nasdaq to provide us with written confirmation of compliance.

On July 27, 2022, the Company announced that its Board of Directors has appointed Paul F. Hickey as President and Chief Executive Officer and a member of the Board of Directors, effective August 15, 2022. Dan W. Gladney, current Chair of the Board of Directors, assumed a more active role as Executive Chair, supporting Mr. Hickey and the Company on strategic matters.

On September 16, 2022, the Company was awarded a $300 thousand, Small Business Innovation Research grant for the development of ReShape’s DBSN device. This device utilizes its proprietary vagus nerve block (vBloc) technology platform, combined with vagus nerve stimulation, for the treatment of Type 2 diabetes and metabolic disorders. Specifically, the grant will fund development of the device for the treatment of hypoglycemia.

RISK FACTORS

An investment in our securities is speculative and involves a high degree of risk and uncertainty. You should carefully consider the risks described below, together with the other information contained in this registration statement, including the consolidated financial statements and notes thereto, before deciding to invest in our securities. The occurrence of any of the events described below could have a material adverse effect on our business, financial condition, results of operations, cash flows, prospects or the value of our common stock. These risks are not the only ones that we face. Additional risks not currently known to us or that we currently deem immaterial also may impair our business.

Risks Related to Our Business and Industry

If we are unable to either substantially improve our operating results or obtain additional financing, we may be unable to continue as a going concern.

We currently do not generate revenue sufficient to offset operating costs and anticipate such shortfalls to continue, partially due to the unpredictability of new variants of COVID-19, which has resulted and may continue to result in a slow-down of elective surgeries and restrictions in some locations. As of September 30, 2022, we had net working capital of approximately $6.1 million, primarily due to cash and cash equivalents and restricted cash of $6.2 million. Additionally, our anticipated expansion of our product portfolio and future products may not come to fruition. Our principal source of liquidity as of September 30, 2022 consisted of approximately $6.2 million of cash and cash equivalents and restricted cash and $2.2 million of accounts receivable. Based on our available cash resources, we may not have sufficient cash on hand to fund our current operations for more than 12 months from the date of filing this prospectus. This condition raises substantial doubt about our ability to continue as a going concern.

Public health crises, such as the COVID-19 pandemic, have had, and could in the future have, a negative effect on our business.

Pandemics or disease outbreaks, such as the COVID-19 pandemic, have created and may continue to create significant volatility, uncertainty and economic disruption in the markets we sell our products into and operate in and may negatively impact business and healthcare activity globally. In response to the COVID-19 pandemic, governments around the world have imposed measures designed to reduce the transmission of COVID-19. In particular, elective procedures, such as the Lap-Band procedure, were delayed or cancelled, there was a significant reduction in physician office visits, and hospitals postponed or canceled purchases as well as limited or eliminated services. While elective procedures have increased from the reduced levels during the height of the COVID-19 pandemic, the reduction in elective procedures has had, and we believe may continue to have, a negative impact on the sales of our products. The extent to which fear of exposure to or actual effects of COVID-19, new variants, disease outbreak, epidemic or a similar widespread health concern impacts our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence.

We may be unable to attract and retain management and other personnel we need to succeed.

Our success depends on the services of our senior management and other key employees. The loss of the services of one or more of our officers or key employees could delay or prevent the commercialization of our Lap-Band System, ReShapeCare, ReShape Marketplace, Lap-Band 2.0, the Obalon Balloon System, and the development of our DBSN device. Our continued growth will require hiring a number of qualified clinical, scientific, commercial and administrative personnel. Accordingly, recruiting and retaining such personnel in the future will be critical to our success. There is intense competition from other companies and research and academic institutions for qualified personnel in the areas of our activities. If we fail to identify, attract, retain and motivate these highly skilled personnel, we may be unable to continue our development and commercialization activities.

The shares of series C convertible preferred stock issued in connection with our acquisition of ReShape Medical have certain rights and preferences senior to our common stock, including a liquidation preference that is senior to our common stock.

There are currently 95,388 shares of our series C convertible preferred stock outstanding, which are convertible into a total of 10 shares of our common stock. We originally issued the shares of our series C convertible preferred stock in connection with our acquisition of ReShape Medical. The series C convertible preferred stock has a liquidation preference of $274.88 per share, or approximately $26.2 million in the aggregate. In general, the series C convertible preferred stock is entitled to receive dividends (on an as-if-converted-to-common stock basis) actually paid on shares of common stock when, as and if such dividends are paid on shares of common stock. No other dividends will be paid on shares of series C convertible preferred stock. Except in connection with the election of directors and limited protective provisions, the series C convertible preferred stock generally does not have voting rights.

Table of Contents

However, as long as any shares of series C convertible preferred stock remain outstanding, we cannot, without the affirmative vote of holders of a majority of the then-outstanding shares of series C convertible preferred stock, (a) alter or change adversely the powers, preferences or rights given to the series C convertible preferred stock (including by the designation, authorization, or issuance of any shares of preferred stock that purports to have equal rights with, or be senior in rights or preferences to, the series C convertible preferred stock), (b) alter or amend the series C convertible preferred stock certificate of designation, (c) amend our certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of series C convertible preferred stock, (d) increase the number of authorized shares of series C convertible preferred stock, (e) except for stock dividends or distributions for which adjustments are to be made pursuant to the Series C Certificate of Designation, pay dividends on any shares of capital stock of the Company, or (f) enter into any agreement with respect to any of the foregoing.

No Obalon directors, officers or employees continued with ReShape which could hinder the ability to transfer the Obalon technology, restart manufacturing operations and maintain FDA regulatory compliance for the Obalon Balloon System and negatively impact our results of operations.

Following the consummation of the merger, no directors, officers or employees of Obalon continued with ReShape. In order to restart manufacturing of the Obalon Balloon System, ReShape would have to hire and train new personnel to appropriately perform manufacturing operations that meet required performance specifications and maintain quality system and regulatory compliance related to the Obalon Balloon System without the knowledge and expertise of the Obalon management team, including completing a FDA-mandated post-approval study which was halted due to the effects of COVID-19. Obalon’s prior suppliers have not supplied Obalon since Obalon halted manufacturing and they may be unwilling or unable to supply ReShape on the prior terms or at all. Obalon has not manufactured or shipped products to customers since March 2020 and customers may not accept a relaunch of the Obalon Balloon System by ReShape.

We are a medical device company with a limited history of operations and sales, and we cannot assure you that we will ever generate substantial revenue or be profitable.

We are a medical device company with a limited operating history upon which you can evaluate our business. The success of our business will depend on our ability to generate increased sales and control costs, as well as our ability to obtain additional regulatory approvals needed to market new versions of our Lap-Band System, ReShapeCare, ReShape Marketplace, Obalon Balloon System, or regulatory approvals needed to market our DBSN device and any other products we may develop in the future, all of which we may be unable to do. If we are unable to successfully market our Lap-Band System for its indicated use, successfully launch ReShapeCare and ReShape Marketplace, re-introduce the Obalon Balloon System, or develop and commercialize the DBSN device, we may never become profitable and may have to cease operations as a result. Our lack of a significant operating history also limits your ability to make a comparative evaluation of us, our products and our prospects.

Previously, we recorded a non-cash indefinite-lived intangible assets impairment loss, which significantly impacted our results of operations, and we may be exposed to additional impairment losses that could be material.

We conduct our annual indefinite-lived intangible assets impairment analysis during the fourth quarter of each year or when circumstances suggest that an indicator for impairment may be present. Previously, we performed a qualitative impairment analysis of the in-process research and development (“IPR&D”). Due to delays in the clinical trials experienced, we revised its expectations of when revenues would commence for the ReShape Vest, thus reducing the projected near-term future net cash flows related to the ReShape Vest. During the quarter ended September 30, 2022, we stopped the clinical trials for the ReShape Vest and closed out the previous trials that occurred, as significant additional clinical work and cost would be required to achieve regulatory approval for the ReShape Vest. As such, we determined the carrying value of the IPR&D asset was impaired and recognized a non-cash impairment charge of approximately $6.9 million on the condensed consolidated balance sheet as of September 30, 2022, which reduced the value of this asset to zero. In the future, we may have additional impairments requiring us to record an impairment loss related to our remaining indefinite-lived and finite-lived intangible assets, which could also have a material adverse effect on our results of operations.

We incur significant costs as a result of operating as a public company, and our management is required to devote substantial time to compliance initiatives.

As a public company, we incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), as well as rules subsequently implemented by the SEC have imposed various requirements on public companies, including establishment and maintenance of effective disclosure and financial controls and changes in corporate

8

Table of Contents

governance practices. Our management and other personnel devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations result in increased legal and financial compliance costs and will make some activities more time-consuming and costly.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal controls for financial reporting and disclosure. In particular, we are required to perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our testing may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses. We have incurred and continue to expect to incur significant expense and devote substantial management effort toward ensuring compliance with Section 404. Moreover, if we do not comply with the requirements of Section 404, or if we identify deficiencies in our internal controls that are deemed to be material weaknesses, the market price of our stock could decline and we could be subject to sanctions or investigations by the SEC or other regulatory authorities, which would entail expenditure of additional financial and management resources.

For example, our management assessed the effectiveness of our internal control over financial reporting as of September 30, 2022, and determined that our internal control over financial reporting was not effective at a reasonable assurance level due to a material weaknesses in our internal control over financial reporting. We had insufficient internal resources with appropriate accounting and finance knowledge and expertise to design, implement, document and operate effective internal controls around our financial reporting process. The insufficient internal resources resulted in a lack of review over our weighted average share calculation spreadsheet which included a formula error resulting in the inaccurate reporting of our earnings per share. We are currently implementing our remediation plan to address the material weaknesses identified above. Such measures include: hiring additional accounting personnel to ensure timely reporting of significant matters; designing and implementing controls to formalize roles and review responsibilities to align with our team’s skills and experience and designing and implementing formalized controls; and designing and implementing formal processes, policies and procedures supporting our financial close process.

General economic and political conditions could have a material adverse effect on our business.

External factors can affect our financial condition. Such external factors include general domestic and global economic conditions, such as interest rates, tax law including tax rate changes, and factors affecting global economic stability, and the political environment regarding healthcare in general. We cannot predict to what extent the global economic conditions may negatively impact our business. For example, negative conditions in the credit and capital markets could impair our ability to access the financial markets for working capital and could negatively impact our ability to borrow.

We face significant uncertainty in the industry due to government healthcare reform.

In the United States, there have been and continue to be a number of legislative initiatives to contain healthcare costs. The Patient Protection and Affordable Care Act, as amended, (the “Affordable Care Act”) as well as any future healthcare reform legislation, may have a significant impact on our business. The impact of the Affordable Care Act on the health care industry is extensive and includes, among other things, the federal government assuming a larger role in the health care system, expanding healthcare coverage of United States citizens and mandating basic healthcare benefits.

Congress regularly considers legislation to replace or repeal elements or all of the Affordable Care Act. At this time, it is not clear whether the Affordable Care Act will be repealed in whole or in part, and, if it is repealed, whether it will be replaced in whole or in part by another plan and what impact those changes will have on coverage and reimbursement for healthcare items and services covered by plans that were authorized by the Affordable Care Act. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, and also indirectly affect the amounts that private payers are willing to pay. In addition, any healthcare reforms enacted in the future may, like the Affordable Care Act, be phased in over a number of years but, if enacted, could reduce our revenue, increase our costs, or require us to revise the ways in which we conduct business or put us at risk for loss of business. In addition, our results of operations, financial position and cash flows could be materially adversely affected by changes under the Affordable Care Act and changes under any federal or state legislation adopted in the future.

We are subject, directly or indirectly, to United States federal and state healthcare fraud and abuse and false claims laws and regulations. Prosecutions under such laws have increased in recent years and we may become subject to such litigation. If we are unable to, or have not fully complied with such laws, we could face substantial penalties.

Our operations are directly, or indirectly through customers, subject to various state and federal fraud and abuse laws, including, without limitation, the federal Anti-Kickback Statute and federal False Claims Act. These laws may impact, among other things, our sales, marketing and education programs.

The federal Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or service, for which payment may be made under a federal healthcare program such as the Medicare and Medicaid programs. Several courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered business, the statute has been violated. The Anti-Kickback Statute is broad and, despite a series of narrow safe harbors, prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Penalties for violations of the federal Anti-Kickback Statute include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs. Many states have also adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs.

The federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. The frequency of filing qui tam actions has increased significantly in recent years, causing greater numbers of medical device, pharmaceutical and healthcare companies to have to defend a False Claim Act action. When an entity is determined to have violated the federal False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states have also enacted laws modeled after the federal False Claims Act.

We are unable to predict whether we could be subject to actions under any of these laws, or the impact of such actions. If we are found to be in violation of any of the laws described above or other applicable state and federal fraud and abuse laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from government healthcare reimbursement programs and the curtailment or restructuring of our operations.

Failure to protect our information technology infrastructure against cyber-based attacks, network security breaches, service interruptions or data corruption could materially disrupt our operations and adversely affect our business.

The operation of our business depends on our information technology systems. We rely on our information technology systems to, among other things, effectively manage sales and marketing data, accounting and financial functions, inventory management, product development tasks, clinical data, customer service and technical support functions. Our information technology systems are vulnerable to damage or interruption from earthquakes, fires, floods and other natural disasters, terrorist attacks, power losses, computer system or data network failures, security breaches, data corruption, and cyber-based attacks. Cyber-based attacks can include computer viruses, computer denial-of-service attacks, phishing attacks, worms, and other malicious software programs or other attacks, covert introduction of malware to computers and networks, impersonation of authorized users, and efforts to discover and exploit any design flaws, bugs, security vulnerabilities, or security weaknesses, as well as intentional or unintentional acts by employees or other insiders with access privileges, intentional acts of vandalism by third parties and sabotage. In addition, federal, state, and international laws and regulations, such as the General Data Protection Regulation adopted by the European Union and EEA countries can expose us to enforcement actions and investigations by regulatory authorities, and potentially result in regulatory penalties and significant legal liability, if our information technology security efforts fail. In addition, a variety of our software systems are cloud-based data management applications, hosted by third-party service providers whose security and information technology systems are subject to similar risks.

We operate in a highly competitive industry that is subject to rapid change. If our competitors are able to develop and market products that are safer or more effective than our products, our commercial opportunities will be reduced or eliminated.

The health care industry is highly competitive, subject to rapid change and significantly affected by new product introductions and other market activities of industry participants. The obesity treatment market in which we operate has grown significantly in

10

Table of Contents

recent years and is expected to continue to expand as technology continues to evolve and awareness of the need to treat the obesity epidemic grows. Although we are not aware of any competitors in the neuroblocking market, we face potential competition from pharmaceutical and surgical obesity treatments. Many of our competitors in the obesity treatment field have significantly greater financial resources and expertise in research and development, manufacturing, preclinical testing, clinical trials, obtaining regulatory approvals and marketing approved products than we do. Smaller or early-stage companies may also prove to be significant competitors, particularly if they pursue competing solutions through collaborative arrangements with large and established companies, such as Allergan, Boston Scientific, LivaNova PLC, Johnson & Johnson, Medtronic or St. Jude Medical. Our competitors may develop and patent processes or products earlier than us, obtain regulatory approvals for competing products more rapidly than we are able to and develop more effective, safer and less expensive products or technologies that would render our products non-competitive or obsolete.

Our ability to use net operating losses (“NOL”) carryforwards may be limited.

Our ability to use our federal and state NOL carryforwards to offset potential future taxable income is dependent upon our generation of future taxable income before the expiration dates of the NOL carryforwards, and we cannot predict with certainty when, or whether we will generate sufficient taxable income to use all of our NOL carryforwards. As of September 30, 2022, ReShape had U.S. federal net operating loss carryforwards of $178.2 million. Of the total U.S. federal net operating loss carryforwards at September 30, 2022, $1.2 million is subject to a 20 year carryover period and began expiring in 2021. Losses generated beginning in 2018 will carryover indefinitely. ReShape had state net operating loss carryforwards of $280.9 million at September 30, 2022, and had foreign net operating loss carryforwards of $0.2 million at September 30, 2022. Net operating loss carryforwards of ReShape are subject to review and possible adjustment by the taxing authorities. With certain exceptions (e.g. the net operating loss carryforwards), ReShape is no longer subject to U.S. federal, state or local examinations by tax authorities for years prior to 2016. There are no tax examinations currently in progress.

ReShape’s ability to utilize its net operating loss carryforwards, tax credits, and built-in items of deduction, including capitalized start-up costs and research and development costs, has been, and may continue to be substantially limited due to ownership changes. These ownership changes limit the amount of net operating loss carryforwards, credits and built-in items of deduction that can be utilized annually to offset future taxable income. In general, an ownership change, as defined in IRC Section 382, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50% of the outstanding stock of a company by certain stockholders or public groups. Due to the valuation allowance against deferred tax assets at September 30, 2022, the net effect of any further limitation will have no impact on results of operations.

Risks Associated with Development and Commercialization of the Lap-Band System, ReShapeCare, Lap-Band 2.0 System, Obalon Balloon System, and the DBSN device

Our efforts to increase revenue from our Lap-Band System, ReShapeCare, Lap-Band 2.0 System, Obalon Balloon System, and commercialize DBSN device and expanded line of bariatric surgical accessories, including ReShape Calibration Tubes, may not succeed or may encounter delays which could significantly harm our ability to generate revenue.

Our ability to generate revenue will depend upon the sales of our Lap-Band System, expanded line of bariatric surgical accessories and ReShapeCare, the successful relaunch and commercialization of the Obalon Balloon System, and successful commercialization of our DBSN device (if approved for sale). Our efforts to commercialize these products may not succeed for a number of reasons, including:

11

Table of Contents

Besides requiring physician adoption, market acceptance of our products will depend on successfully communicating the benefits of our products to three additional constituencies involved in deciding whether to treat a particular patient using our products: (1) the potential patients themselves; (2) institutions such as hospitals, where the procedure would be performed and opinion leaders in these institutions; and (3) third-party payers, such as private healthcare insurers and governmental payers, such as Medicare and Medicaid in the United States, which would ultimately bear most of the costs of the various providers and equipment involved in our Lap-Band System, ReShapeCare, Obalon Balloon System, and DBSN device (if approved for sale). Marketing to each of these constituencies requires a different marketing approach, and we must convince each of these groups of the efficacy and utility of our products to be successful.

During the three and nine months ended September 30, 2022 and 2021, there was minimal revenue for ReShapeCare. There was no revenue or gross profit recorded for the ReShape Vest or DBSN device for the three months and nine months ended September 30, 2022 and 2021 as these two products are still in the development stage. There was also no revenue recorded for the Obalon line.

If our products, or any other therapy or products for other gastrointestinal diseases and disorders that we may develop, do not achieve an adequate level of acceptance by the relevant constituencies, we may not generate significant product revenue and may not become profitable. If we complete the offering contemplated by this prospectus, we believe we will have sufficient cash on hand to execute on our goal of becoming profitable within the next 18 months. This estimated timeline could be compressed or extended depending on many factors, including revenue growth from new product introductions, strategic investments not yet foreseen, and other risks and uncertainties due to the general business, economic, regulatory, market and financial conditions. The company could achieve its goal of becoming profitable within the next 18 months by becoming cash flow positive, achieving positive EBITDA, or positive net income.

We may not be able to obtain required regulatory approvals for our DBSN device in a cost-effective manner or at all, which could adversely affect our business and operating results.

The production and marketing of our DBSN device, and our ongoing research and development, preclinical testing and future potential clinical trial activities are subject to extensive regulation and review by numerous governmental authorities both in the

12

Table of Contents

United States and abroad. U.S. and foreign regulations applicable to medical devices are wide-ranging and govern, among other things, the development, testing, marketing and premarket review of new medical devices, in addition to regulating manufacturing practices, reporting, advertising, exporting, labeling and record keeping procedures. We are required to obtain regulatory approval before we can market our DBSN device in the United States and certain foreign countries. The regulatory process will require significant time, effort and expenditures to bring products to market, and it is possible that our DBSN device will not be approved for sale. Even if regulatory approval of our DBSN device is granted, it may not be granted within the timeframe that we expect, which could have an adverse effect on our operating results and financial condition. Even after our DBSN device is approved by the FDA, we may have ongoing responsibilities under FDA regulations, non-compliance of which could result in the subsequent withdrawal of such approvals, or such approvals could be withdrawn due to the occurrence of unforeseen problems following initial approval. We also are subject to medical device reporting regulations that require us to report to the FDA if any of our products causes or contributes to a death or serious injury or if a malfunction were it to occur might cause or contribute to a death or serious injury. Any failure to obtain regulatory approvals on a timely basis or the subsequent withdrawal of such approvals could prevent us from successfully marketing our products, which could adversely affect our business and operating results.

We depend on clinical investigators and clinical sites to enroll patients in our clinical trials, and on other third parties to manage the trials and to perform related data collection and analysis, and, as a result, we may face costs and delays that are outside of our control.

While we currently do not have any active clinical trials enrolling patients, we may in the future need to rely on clinical investigators and clinical sites to enroll patients in our clinical trials and other third parties to manage the trials and to perform related data collection and analysis. However, we may not be able to control the amount and timing of resources that clinical sites may devote to our clinical trials. If these clinical investigators and clinical sites fail to enroll a sufficient number of patients in our clinical trials, ensure compliance by patients with clinical protocols or comply with regulatory requirements, we will be unable to complete these trials, which could prevent us from obtaining or maintaining regulatory approvals for our product. Our agreements with clinical investigators and clinical trial sites for clinical testing place substantial responsibilities on these parties and, if these parties fail to perform as expected, our trials could be delayed or terminated. If these clinical investigators, clinical sites or other third parties do not carry out their contractual duties or obligations or fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to their failure to adhere to our clinical protocols, regulatory requirements or for other reasons, our clinical trials may be extended, delayed or terminated, or the clinical data may be rejected by the FDA, adversely affecting our ability to successfully commercialize our product.

Modifications to the Lap-Band and Lap-Band 2.0 system may require additional approval from regulatory authorities, which may not be obtained or may delay our commercialization efforts.

The FDA and our European Notified Body require medical device companies to initially make and document a determination of whether or not a modification requires a new approval, supplement or clearance; however, some of these regulatory authorities can review a company’s decision. Any modifications to an approved device that could significantly affect its safety or efficacy, or that would constitute a major change in its intended use could require additional clinical studies and separate regulatory applications. Product changes or revisions will require all the regulatory steps and associated risks discussed above possibly including testing, regulatory filings and clinical studies. We may not be able to obtain approval of supplemental regulatory approvals for product modifications, new indications for our product or new products. Delays in obtaining future clearances would adversely affect our ability to introduce new or enhanced products in a timely manner, which in turn would harm our commercialization efforts and future growth.

If we or our suppliers fail to comply with ongoing regulatory requirements, or if we experience unanticipated product problems, our Lap-Band System could be subject to restrictions or withdrawal from the market.

Any product for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data and promotional activities for such product, will be subject to continual review and periodic inspections by our European Notified Body and the FDA and other regulatory bodies. In particular we and our manufacturers and suppliers are required to comply with ISO requirements, Good Manufacturing Practices, which for medical devices is called the Quality System Regulation (“QSR”), and other regulations which cover the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of any product for which we obtain marketing approval. The FDA enforces the QSR through inspections, which may be unannounced, and the CE system enforces its certification through inspections and audits as well. Our quality system has received certification of compliance to the requirements of ISO 13485:2016 and will have to continue to successfully complete such inspections to maintain regulatory approvals for sales outside of the United States. Failure by us or one of

13

Table of Contents

our manufacturers or suppliers to comply with statutes and regulations administered by the FDA, CE authorities and other regulatory bodies, or failure to adequately respond to any observations, could result in enforcement actions against us or our manufacturers or suppliers, including, restrictions on our product or manufacturing processes, withdrawal of the product from the market, voluntary or mandatory recall, fines, suspension of regulatory approvals, product seizures, injunctions or the imposition of civil or criminal penalties.

If any of these actions were to occur it would harm our reputation and cause our product sales to suffer. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with applicable regulatory requirements. If the FDA or any other regulatory body finds their compliance status to be unsatisfactory, our commercialization efforts could be delayed, which would harm our business and our results of operations.

Additionally, if the FDA determines that our promotional materials, training or other activities constitute promotion of an unapproved use, we could be subject to significant liability, the FDA could request that we cease, correct or modify our training or promotional materials or subject us to regulatory enforcement actions. It is also possible that other federal, state or foreign enforcement authorities might take action if they consider our training or other promotional materials to constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement.

We are subject to medical device reporting regulations that require us to report to the FDA, Competent Authorities or other governmental authorities in other countries if our products cause or contribute to a death or serious injury or malfunction in a way that would be reasonably likely to contribute to death or serious injury if the malfunction were to recur. The FDA and similar governmental authorities in other countries have the authority to require the recall of our products in the event of material deficiencies or defects in design or manufacturing. A government mandated, or voluntary, recall by us could occur as a result of component failures, manufacturing errors or design defects, including defects in labeling. Any recall would divert managerial and financial resources and could harm our reputation with customers. There can be no assurance that there will not be product recalls in the future or that such recalls would not have a material adverse effect on our business. Once the product is approved and implanted in a large number of patients, infrequently occurring adverse events may appear that were not observed in the clinical trials. This could cause health authorities in countries where the product is available to take regulatory action, including marketing suspension and recall.

We may be unable to manage our growth effectively.

Our business strategy entails significant future growth. For example, we will have to expand existing operations in order to increase revenue from our Lap-Band System and ReShapeCare, re-introduce the Obalon Balloon System, and develop our DBSN device, conduct additional clinical trials, increase our contract manufacturing capabilities, hire and train new personnel to handle the marketing and sales of our product, assist patients and healthcare providers in obtaining reimbursement for the use of our product and create and develop new applications for our technology. This growth may place significant strain on our management and financial and operational resources. Successful growth is also dependent upon our ability to implement appropriate financial and management controls, systems and procedures. Our ability to effectively manage growth depends on our success in attracting and retaining highly qualified personnel, for which the competition may be intense. If we fail to manage these challenges effectively, our business could be harmed.

We face the risk of product liability claims that could be expensive, divert management’s attention and harm our reputation and business. We may not be able to obtain adequate product liability insurance.

Our business exposes us to a risk of product liability claims that is inherent in the testing, manufacturing and marketing of medical devices. The medical device industry has historically been subject to extensive litigation over product liability claims. We may be subject to product liability claims if our products cause, or appear to have caused, an injury. Claims may be made by consumers, healthcare providers, third-party strategic collaborators or others selling our products.

We have product liability insurance, which covers the use of our products in our clinical trials and any commercial sales, in an amount we believe is appropriate. Our current product liability insurance may not continue to be available to us on acceptable terms, if at all, and, if available, the coverage may not be adequate to protect us against any future product liability claims. If we are unable to obtain insurance at an acceptable cost and on acceptable terms for an adequate coverage amount, or otherwise to protect against potential product liability claims, we could be exposed to significant liabilities, which may harm our business. A product liability claim, recall or other claim with respect to uninsured liabilities or for amounts in excess of insured liabilities could have a material adverse effect on our business, financial condition and results of operations. These liabilities could prevent or interfere with our

14

Table of Contents

product commercialization efforts. Defending a suit, regardless of merit, could be costly, could divert management attention and might result in adverse publicity, which could result in the withdrawal of, or inability to recruit, clinical trial volunteers or result in reduced acceptance of our products in the market.

We may be subject to product liability claims even if it appears that the claimed injury is due to the actions of others. For example, we rely on the expertise of surgeons and other associated medical personnel to perform the medical procedure to implant and remove our products and to perform the related therapy. If these medical personnel are not properly trained or are negligent, the therapeutic effect of our products may be diminished or the patient may suffer critical injury, which may subject us to liability. In addition, an injury that is caused by the negligence of one of our suppliers in supplying us with a defective component that injures a patient could be the basis for a claim against us. A product liability claim, regardless of its merit or eventual outcome, could result in decreased demand for our products; injury to our reputation; diversion of management’s attention; withdrawal of clinical trial participants; significant costs of related litigation; substantial monetary awards to patients; product recalls or market withdrawals; loss of revenue; and the inability to commercialize our products under development.

Risks Related to Intellectual Property

If we are unable to obtain or maintain intellectual property rights relating to our technology and neuroblocking therapy, the commercial value of our technology and any future products will be adversely affected and our competitive position will be harmed.

Our commercial success depends in part on our ability to obtain protection in the United States and other countries for our Lap-Band System, ReShapeCare, Obalon Balloon System, ReShape Vest and DBSN device by establishing and maintaining intellectual property rights relating to or incorporated into our technology and products. We own numerous U.S. and foreign patents and have numerous patent applications pending, most of which pertain to treating gastrointestinal disorders and the treatment of obesity. We have also received or applied for additional patents outside the United States. Our pending and future patent applications may not issue as patents or, if issued, may not issue in a form that will provide us any competitive advantage. We expect to incur substantial costs in obtaining patents and, if necessary, defending our proprietary rights. The patent positions of medical device companies, including ours, can be highly uncertain and involve complex and evolving legal and factual questions. We do not know whether we will obtain the patent protection we seek, or that the protection we do obtain will be found valid and enforceable if challenged. If we fail to obtain adequate protection of our intellectual property, or if any protection we obtain is reduced or eliminated, others could use our intellectual property without compensating us, resulting in harm to our business. We may also determine that it is in our best interests to voluntarily challenge a third-party’s products or patents in litigation or administrative proceedings, including patent interferences, re-examinations or under more recently promulgated Inter Partes Review proceedings, depending on when the patent application was filed. In the event that we seek to enforce any of our owned or exclusively licensed patents against an infringing party, it is likely that the party defending the claim will seek to invalidate the patents we assert, which, if successful could result in the loss of the entire patent or the relevant portion of our patent, which would not be limited to any particular party. Any litigation to enforce or defend our patent rights, even if we were to prevail, could be costly and time-consuming and could divert the attention of our management and key personnel from our business operations. Even if we were to prevail in any litigation, we cannot assure you that we can obtain an injunction that prevents our competitors from practicing our patented technology. Our competitors may independently develop similar or alternative technologies or products without infringing any of our patent or other intellectual property rights, or may design around our proprietary technologies.

We cannot assure you that we will obtain any patent protection that we seek, that any protection we do obtain will be found valid and enforceable if challenged or that it will confer any significant commercial advantage. U.S. patents and patent applications may also be subject to interference proceedings and U.S. patents may be subject to re-examination proceedings in the U.S. Patent and Trademark Office (“USPTO”), or under more recently promulgated Inter Partes Review proceedings, depending on when the patent application was filed, and foreign patents may be subject to opposition or comparable proceedings in the corresponding foreign patent offices, which proceedings could result in either loss of the patent or denial of the patent application, or loss or reduction in the scope of one or more of the claims of, the patent or patent application. In addition, such interference, re-examination and opposition proceedings may be costly. Moreover, the U.S. patent laws have recently changed with the adoption of the America Invents Act (“AIA”), possibly making it easier to challenge patents. Some of our technology was, and continues to be, developed in conjunction with third parties, and thus there is a risk that such third parties may claim rights in our intellectual property. Thus, any patents that we own or license from others may provide limited or no protection against competitors. Our pending patent applications, those we may file in the future, or those we may license from third parties, may not result in patents being issued. If issued, they may not provide us with proprietary protection or competitive advantages against competitors with similar technology.

Table of Contents

We may lose important patents or patent rights if we do not timely pay required patent fees or annuities.

We have, from time to time, experienced delays in the payment of required patent fees or annuities. Non-payment or delay in payment of patent fees or annuities, whether intentional or unintentional, may result in loss of patents or patent rights important to our business. Many countries, including certain countries in Europe, have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, including government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the patent. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as do the laws of the United States, particularly in the field of medical products and procedures.

Many of our competitors have significant resources and incentives to apply for and obtain intellectual property rights that could limit or prevent our ability to commercialize our current or future products in the United States or abroad.

Many of our competitors who have significant resources and have made substantial investments in competing technologies may seek to apply for and obtain patents that will prevent, limit or interfere with our ability to make, use or sell our products either in the U.S. or in international markets. Our current or future U.S. or foreign patents may be challenged, circumvented by competitors or others or may be found to be invalid, unenforceable or insufficient. In most cases in the United States patent applications are published 18 months after filing the application, or corresponding applications are published in other countries, and since publication of discoveries in the scientific or patent literature often lags behind actual discoveries, we cannot be certain that we were the first to make the inventions covered by each of our pending patent applications, or that we were the first to file patent applications for such inventions.

If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology and products could be adversely affected.

In addition to patented technology, we rely on our unpatented proprietary technology, trade secrets, processes and know-how. We generally seek to protect this information by confidentiality agreements with our employees, consultants, scientific advisors and third parties. These agreements may be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently developed by competitors. To the extent that our employees, consultants or contractors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Intellectual property litigation is a common tactic in the medical device industry to gain competitive advantage. If we become subject to a lawsuit, we may be required to expend significant financial and other resources and our management’s attention may be diverted from our business.

There has been a history of frequent and extensive litigation regarding patent and other intellectual property rights in the medical device industry, and companies in the medical device industry have employed intellectual property litigation to gain a competitive advantage. Accordingly, we may become subject to patent infringement claims or litigation in a court of law, or interference proceedings declared by the USPTO to determine the priority of inventions or an opposition to a patent grant in a foreign jurisdiction. We may also become subject to claims or litigation seeking payment of royalties based on sales of our product in connection with licensing or similar joint development arrangements with third parties or in connection with claims of patent infringement.

The defense and prosecution of intellectual property suits, USPTO interference proceedings, reexamination proceedings, or under more recently promulgated Inter Partes Review proceedings, depending on when the patent application was filed, or opposition proceedings and related legal and administrative proceedings, are both costly and time consuming and could result in substantial uncertainty to us. Litigation or regulatory proceedings may also be necessary to enforce patent or other intellectual property rights of ours or to determine the scope and validity of other parties’ proprietary rights. Any litigation, opposition or interference proceedings, with or without merit, may result in substantial expense to us, cause significant strain on our financial resources, divert the attention of our technical and management personnel and harm our reputation. We may not have the financial resources to defend our patents from infringement or claims of invalidity. An adverse determination in any litigation could subject us to significant liabilities to third parties, require us to seek licenses from or pay royalties to third parties or prevent us from manufacturing, selling or using our proposed products, any of which could have a material adverse effect on our business and prospects.

Our Lap-Band System, ReShapeCare, Obalon Balloon System or DBSN device may infringe or be claimed to infringe patents that we do not own or license, including patents that may issue in the future based on patent applications of which we are currently

16

Table of Contents

aware, as well as applications of which we are unaware. For example, we are aware of other companies that are investigating neurostimulation, including neuroblocking, and of patents and published patent applications held by companies in those fields. While we believe that none of such patents and patent applications are applicable to our products and technologies under development, third parties who own or control these patents and patent applications in the United States and abroad could bring claims against us that would cause us to incur substantial expenses and, if such claims are successfully asserted against us, they could cause us to pay substantial damages, could result in an injunction preventing us from selling, manufacturing or using our proposed products and would divert management’s attention. Because patent applications in many countries such as the United States are maintained under conditions of confidentiality and can take many years to issue, there may be applications now pending of which we are unaware, and which may later result in issued patents that our products infringe. If a patent infringement suit were brought against us, we could be forced to stop our ongoing or planned clinical trials, or delay or abandon commercialization of the product that is subject of the suit.

As a result of patent infringement claims, or to avoid potential claims, we may choose or be required to seek a license from a third-party and be required to pay license fees or royalties, or both. A license may not be available at all or on commercially reasonable terms, and we may not be able to redesign our products to avoid infringement. Modification of our products or development of new products could require us to conduct additional clinical trials and to revise our filings with the FDA and other regulatory bodies, which would be time-consuming and expensive. Even if we were able to obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual property. Ultimately, we could be forced to cease some aspect of our business operations if, as a result of actual or threatened patent infringement claims, we are unable to enter into licenses on acceptable terms. This could harm our business significantly.

Risks Relating to Ownership of Our Common Stock

The trading price of our common stock has been volatile and is likely to be volatile in the future.

The trading price of our common stock has been highly volatile. The market price for our common stock will be affected by a number of factors, including:

17

Table of Contents

The stock prices of many companies in the medical device industry have experienced wide fluctuations that have often been unrelated to the operating performance of these companies. Following periods of volatility in the market price of a company’s securities, securities class action litigation often has been initiated against a company. If class action litigation is initiated against us, we may incur substantial costs and our management’s attention may be diverted from our operations, which could significantly harm our business.

Sales of a substantial number of shares of our common stock in the public market by existing stockholders, or the perception that they may occur, could cause our stock price to decline.

Sales of substantial amounts of our common stock by us or by our stockholders, announcements of the proposed sales of substantial amounts of our common stock or the perception that substantial sales may be made, could cause the market price of our common stock to decline. We may issue additional shares of our common stock in follow-on offerings to raise additional capital, upon the exercise of options or warrants, or in connection with acquisitions or corporate alliances. We also plan to issue additional shares to our employees, directors or consultants in connection with their services to us. All of the currently outstanding shares of our common stock are freely tradable under federal and state securities laws, except for shares held by our directors, officers and certain greater than five percent stockholders, which may be subject to holding period, volume and other limitations under Rule 144. Due to these factors, sales of a substantial number of shares of our common stock in the public market could occur at any time and could reduce the market price of our common stock.

We have a significant number of outstanding warrants, which may cause significant dilution to our stockholders, have a material adverse impact on the market price of our common stock and make it more difficult for us to raise funds through future equity offerings.

As of December 27, 2022, we had outstanding 519,198 shares of common stock. In addition, as of that date we had outstanding warrants to acquire 206,819 shares of common stock. The issuance of shares of common stock upon the exercise of warrants would dilute the percentage ownership interest of all stockholders, might dilute the book value per share of our common stock and would increase the number of our publicly traded shares, which could depress the market price of our common stock.

In addition to the dilutive effects described above, the perceived risk of dilution as a result of the significant number of outstanding warrants may cause our common stockholders to be more inclined to sell their shares, which would contribute to a downward movement in the price of our common stock. Moreover, the perceived risk of dilution and the resulting downward pressure on our common stock price could encourage investors to engage in short sales of our common stock, which could further contribute to price declines in our common stock. The fact that our stockholders and warrant holders can sell substantial amounts of our common stock in the public market, whether or not sales have occurred or are occurring, could make it more difficult for us to raise additional funds through the sale of equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate, or at all.

If we fail to meet all applicable Nasdaq Capital Market requirements, Nasdaq could delist our common stock, which could adversely affect the market liquidity of our common stock and the market price of our common stock could decrease.

Nasdaq monitors our ongoing compliance with its minimum listing requirements and if we fail to meet those requirements and cannot cure such failure in the prescribed period of time, our common stock could be subject to delisting from the Nasdaq market. In the event that our common stock is delisted from the Nasdaq Capital Market and is not eligible for quotation or listing on another

18

Table of Contents

market or exchange, trading of our common stock could be conducted only in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our common stock, and there would likely also be a reduction in our coverage by securities analysts and the news media, which could cause the price of our common stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on a major exchange.

For example, on July 19, 2022, we received a written notice from The Nasdaq Stock Market indicating that we were not in compliance with the $1.00 minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The Nasdaq Capital Market. The notice provided that we have until January 16, 2023 to regain compliance. If at any time during this period the closing bid price of our common stock is at least $1.00 per share for a minimum of 10 consecutive business days, Nasdaq will provide us with a written confirmation of compliance and the matter will be closed. In order to regain compliance with the bid price requirement, we effected a 1-for-50 reverse stock split of our issued and outstanding common stock on December 23, 2022. Following the reverse stock split, the closing bid price of our common stock has been at least $1.00 for at least 10 consecutive business days as of the date of this prospectus. Therefore, we expect Nasdaq to provide us with written confirmation of compliance.

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital for general corporate purposes, in the future we may offer additional shares of our common stock or other securities convertible into or exchangeable for our common stock at prices that may be lower than the current price per share of our common stock. In addition, investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock, or securities convertible or exchangeable into common stock, in future transactions may be higher or lower than the price per share paid by investors in prior offerings.

Our organizational documents and Delaware law make a takeover of our company more difficult, which may prevent certain changes in control and limit the market price of our common stock.

Our certificate of incorporation and bylaws and Section 203 of the Delaware General Corporation Law contain provisions that may have the effect of deterring or delaying attempts by our stockholders to remove or replace management, engage in proxy contests and effect changes in control. These provisions include:

In addition, as a Delaware corporation, we are subject to Delaware law, including Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder unless certain specific requirements are met as set forth in Section 203. These provisions, alone or together, could have the effect of deterring or delaying changes in incumbent management, proxy contests or changes in control.

19

Table of Contents

These provisions also could discourage proxy contests and make it more difficult for you and other stockholders to elect directors and take other corporate actions. The existence of these provisions could limit the price that investors might be willing to pay in the future for shares of our common stock. Some provisions in our certificate of incorporation and bylaws may deter third parties from acquiring us, which may limit the market price of our common stock.

We have not paid dividends in the past and do not expect to pay dividends in the future, and any return on investment may be limited to the value of our common stock.

We have never paid dividends on our common stock and do not anticipate paying dividends on our common stock in the foreseeable future. The payment of dividends on our common stock will depend on our earnings, financial condition and other business and economic factors affecting us at such time as our board of directors may consider relevant. If we do not pay dividends, our common stock may be less valuable because a return on your investment will only occur if our stock price appreciates.

Risks Related to this Offering

Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use these proceeds effectively.

We intend to use the net proceeds from this offering for working capital and general corporate purposes. Our management will have broad discretion in the application of the net proceeds from this offering and could spend the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. Accordingly, you will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used effectively. Our failure to apply these funds effectively could have a material adverse effect on our business, delay the development of our product candidates and cause the price of our common stock to decline.

Future sales of substantial amounts of our common stock could adversely affect the market price of our common stock.

We may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. If additional capital is raised through the sale of equity or convertible debt securities, or perceptions that those sales could occur, the issuance of these securities could result in further dilution to investors purchasing our common stock in this offering or result in downward pressure on the price of our common stock, and our ability to raise capital in the future.

There is no public market for the common warrants or pre-funded warrants.

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

The common warrants in this offering are speculative in nature.

The common warrants in this offering do not confer any rights of common stock ownership on its holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of our common stock at a fixed price, as the case maybe. In addition, following this offering, the market value of the common warrants, if any, is uncertain and there can be no assurance that the market value of the common warrants will equal or exceed their imputed offering price. The common warrants will not be listed or quoted for trading on any market or exchange.

Holders of the common warrants will not have rights of holders of our common stock until such warrants are exercised.

Until holders of common warrants acquire shares of our common stock upon exercise of the common warrants, holders of common warrants will have no rights with respect to the shares of our common stock underlying such securities. Upon exercise of the common warrants, the holders will be entitled to exercise the rights of a holder of our common stock only as to matters for which the record date occurs after the exercise.

A large number of shares issued in this offering may be sold in the market following this offering, which may depress the market price of our common stock.

A large number of shares issued in this offering may be sold in the market following this offering, which may depress the market price of our common stock. Sales of a substantial number of shares of our common stock in the public market following this offering could cause the market price of our common stock to decline. If there are more shares of our common stock offered for sale than buyers are willing to purchase, then the market price of our common stock may decline to a market price at which buyers are willing to purchase the offered shares of our common stock and sellers remain willing to sell the shares. All of the securities issued in the offering will be freely tradable without restriction or further registration under the Securities Act.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements contained in this prospectus, or filings with the SEC and our public releases, that are not purely historical are forward-looking statements within the meaning of applicable securities laws. Our forward-looking statements include, but are not limited to, statements regarding our “expectations,” “hopes,” “beliefs,” “intentions” or “strategies” regarding the future. In addition, any statements that refer to projections, forecasts, or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should” and “would,” as well as similar expressions, may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward looking. Such statements, include, but are not limited to, statements contained in this prospectus relating to our business strategy, our future operating results and liquidity and capital resources outlook. Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Our actual results may differ materially from those contemplated by the forward-looking statements. They are neither statements of historical fact nor guarantees of assurance of future performance. We caution you therefore against relying on any of these forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, without limitation, our ability to raise capital to fund continuing operations; our ability to protect our intellectual property rights; the impact of any infringement actions or other litigation brought against us; competition from other providers and products; our ability to develop and commercialize products and services; changes in government regulation; our ability to complete capital raising transactions; and other factors (including the risks contained in the section of this prospectus entitled “Risk Factors”) relating to our industry, our operations and results of operations. Actual results may differ significantly from those anticipated, believed, estimated, expected, intended or planned.

Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them. We cannot guarantee future results, levels of activity, performance or achievements. Except as required by applicable law, including the securities laws of the United States, we do not intend to update any of the forward-looking statements to conform these statements to actual results.

This prospectus may contain assumptions, expectations, projections, intentions and beliefs about future events. These statements are intended as forward-looking statements. We may also from time to time make forward-looking statements in other documents and reports that are filed with or submitted to the SEC, in other information sent to our security holders, and in other written materials. We also caution that assumptions, expectations, projections, intentions and beliefs about future events may and often do vary from actual results and the differences can be material.

CAPITALIZATION

The following table sets forth our actual cash and cash equivalents and capitalization, each as of September 30, 2022, and as adjusted to give effect to the issuance and sale of securities in this offering at an assumed public offering price of $7.53 per share, which is the last reported sale price for our common stock on the Nasdaq Capital Market on January 5, 2023, and an aggregate offering amount of $8,500,000, after deducting the underwriter discount and estimated offering expenses payable by us.

The as adjusted information set forth below is illustrative only and will be adjusted based on the actual public offering price and other terms of this offering determined at pricing. You should read this information together with our consolidated financial statements.

Except as otherwise noted, all information in this prospectus reflects and assumes (i) no sale of pre-funded warrants in this offering, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis and (ii) no exercise of the common warrants issued in this offering. The above discussion and table are based on 451,919 shares of common stock outstanding as of September 30, 2022 and excludes:

DILUTION

This offering will not be dilutive to new investors. Dilution represents the difference between the assumed public offering price per share of common stock (which forms a part of a unit) and the pro forma net tangible book value per share of our common stock immediately after this offering. Because the pro forma net tangible book value per share is greater than the assumed public offering price per share, investors purchasing our units in this offering will not experience dilution, as illustrated in the table below.

As of September 30, 2022, our net tangible book value was approximately $8.4 million, or $18.65 per share. Net tangible book value per share represents our total tangible assets less our total liabilities, divided by the number of shares of common stock.

Net tangible book value dilution per share of common stock in each unit to new investors represents the difference between the amount per share of common stock in each unit paid by purchasers in this offering and the pro forma net tangible book value per share of our common stock immediately after the completion of this offering. The following table illustrates this per share dilution on an as adjusted basis:

​

The information discussed above is illustrative only, and the dilution information following this offering will depend on the actual public offering price and other terms of this offering determined at pricing. Each $1.00 increase or decrease in the assumed public offering price of $7.53 per unit, based on the last reported sale price for our common stock as reported on the Nasdaq Capital Market on January 5, 2023, would increase or decrease the as adjusted net tangible book value per share after this offering by $0.66 per share, assuming that the number of units offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions payable by us.

We may also increase or decrease the number of units we are offering. An increase of 100,000 in the number of units offered by us would decrease our as adjusted net tangible book value per share by approximately $0.18 and a decrease of 100,000 in the number of units offered by us would increase our as adjusted net tangible book value per share by approximately $0.21, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. The information discussed above is illustrative only and will adjust based on the actual offering price, the actual number of units we offer in this offering, and other terms of this offering determined at pricing.

Except as otherwise noted, all information in this prospectus reflects and assumes (i) no sale of pre-funded warrants in this offering, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis and (ii) no exercise of the common warrants issued in this offering. The above discussion and table are based on 451,919 shares of common stock outstanding as of September 30, 2022 and excludes:

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $7.5 million based on an assumed offering price of $7.53, the last reported sale price of our common stock on the Nasdaq Capital Market on January 5, 2023, and an aggregate offering amount of $8,500,000.

A $1.00 increase or decrease in the assumed public offering price of $7.53 per unit, based on the last reported sale price for our common stock as reported on the Nasdaq Capital Market on January 5, 2023, would increase or decrease the net proceeds to us by approximately $1.0 million, assuming the assumed public offering price of $7.53 per unit remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Similarly, a 100,000 unit increase or decrease in the number of units offered by us, as set forth on the cover page of this prospectus, would increase or decrease the net proceeds to us by approximately $0.7 million, assuming the assumed public offering price of $7.53 per unit remains the same, and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.

We intend to use the net proceeds of this offering to continue implementation of our growth strategies, for working capital and general corporate purposes. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering. The amounts and timing of its actual expenditures will depend on numerous factors, including the status of its product development efforts, sales and marketing activities, technological advances, amount of cash generated or used by its operations and competition. Accordingly, our management will have broad discretion in the application of the net proceeds and investors will be relying on the judgment of its management regarding the application of the proceeds of this offering.

DESCRIPTION OF CAPITAL STOCK

The following is a summary of the rights of our common and preferred stock and some of the provisions of our restated certificate of incorporation, as amended, and restated bylaws, and of the Delaware General Corporation Law, or DGCL. Our authorized capital stock consists of 300,000,000 shares of common stock, $0.001 par value per share, and 10,000,000 shares of undesignated preferred stock, $0.001 par value per share.

As of December 27, 2022, there were 519,198 shares of our common stock outstanding, held by approximately 34 stockholders of record, and 95,388 shares of our series C convertible preferred stock outstanding.

Common Stock

Voting rights

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders. We do not provide for cumulative voting for the election of directors in our restated certificate of incorporation. Accordingly, holders of a majority of the shares of our common stock are able to elect all of our directors. Our restated certificate of incorporation establishes a classified board of directors, to be divided into three classes with staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Subject to the supermajority votes for some matters, other matters shall be decided by the affirmative vote of our stockholders having a majority in voting power of the votes cast by the stockholders present or represented and voting on such matter. Our restated certificate of incorporation and restated bylaws provide that our directors may be removed only for cause and only by the affirmative vote of the holders of at least two-thirds in voting power of the outstanding shares of capital stock entitled to vote thereon. In addition, the affirmative vote of the holders of at least two-thirds in voting power of the outstanding shares of capital stock entitled to vote thereon is required to amend or repeal, or to adopt any provision inconsistent with, several of the provisions of our restated certificate of incorporation.

Dividend rights

Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and then only at the times and in the amounts that our board of directors may determine.

No preemptive or similar rights

Our common stock is not entitled to preemptive or subscription rights, and is not subject to conversion, redemption or sinking fund provisions. The rights, preferences and privileges of the holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future.

Right to receive liquidation distributions

Upon our liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time, subject to prior satisfaction of all outstanding debt and liabilities and the preferential rights of and the payment of liquidation preferences, if any, on any outstanding shares of preferred stock.

Preferred Stock

Pursuant to our restated certificate of incorporation, our board of directors is authorized, subject to limitations prescribed by Delaware law, to issue from time to time up to 10,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each series and to fix the designation, powers, preferences and rights of the shares of each series and any of their qualifications, limitations or restrictions, in each case without further vote or action by our stockholders. Our board of directors is able to increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by our stockholders. Our board of directors may be able to authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock. The issuance of preferred stock, while providing flexibility in connection with possible

acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in control of our company and might adversely affect the market price of our common stock and the voting and other rights of the holders of our common stock.

Series C Convertible Preferred Stock

The material terms and provisions of the shares of series C convertible preferred stock (“Series C Preferred Stock”) are summarized below. This summary of some provisions of the Series C Preferred Stock is not complete. For the complete terms of the Series C Preferred Stock, you should refer to the Certificate of Designation (the “Series C Certificate of Designation”) filed as an exhibit to this prospectus and incorporated herein by reference.

Conversion.    There are currently 95,388 shares of our series C convertible preferred stock outstanding. Each outstanding share of Series C Preferred Stock is convertible, at the option of the holders, into 0.0000078 shares of common stock, rounded up to the nearest whole share, subject to adjustments for stock splits, stock dividends, distributions, subdivisions and combinations. Therefore, as of the date of this prospectus, each of the 10 holders of Series C Preferred Stock is entitled to convert all of their shares of Series C Preferred Stock into an aggregate of one share of common stock per holder.

Dividends.    The Series C Preferred Stock is entitled to receive dividends (on an as-if-converted-to-common stock basis) actually paid on shares of common stock when, as and if such dividends are paid on shares of common stock. No other dividends will be paid on shares of Series C Preferred Stock.

Voting Rights.    In general, the Series C Preferred Stock does not have voting rights. However, as long as any shares of Series C Preferred Stock remain outstanding, the Series C Certificate of Designation provides that we cannot, without the affirmative vote of holders of a majority of the then-outstanding shares of Series C Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series C Preferred Stock (including by the designation, authorization, or issuance of any shares of preferred stock that purports to have equal rights with, or be senior in rights or preferences to, the Series C Preferred Stock), (b) alter or amend the Series C Certificate of Designation, (c) amend our certificate of incorporation or other charter documents in any manner that adversely affects any rights of the holders of Series C Preferred Stock, (d) increase the number of authorized shares of Series C Preferred Stock, (e) except for stock dividends or distributions for which adjustments are to be made pursuant to the Series C Certificate of Designation, pay dividends on any shares of capital stock of the Company, or (f) enter into any agreement with respect to any of the foregoing. Holders of Series C Preferred Stock are entitled to vote for the election of directors of the Company, voting on an as-converted to common stock basis and voting together as a single class with the holders of shares of common stock.

Liquidation.    In the event of a liquidation, the holders of shares of Series C Preferred Stock are entitled to be paid, after and subject to the payment in full of all amounts required to be distributed to the holders of any other shares of the Company outstanding as of the date of our acquisition of ReShape Medical ranking on liquidation prior and in preference to the Series C Preferred Stock, but before any payments to be made to the holders of common stock or any other series of preferred stock, an amount per share equal to the greater of (i) $274.8774, plus any dividends declared but unpaid thereon, or (ii) such amount per share as would have been payable had all shares of Series C Preferred Stock been converted to common stock immediately prior to such liquidation. In addition, in the event we consummate a merger or consolidation with or into another person or other reorganization event in which our common shares are converted or exchanged for securities, cash or other property, or we sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of our assets or we or another person acquire 50% or more of our outstanding shares of common stock, then following such event, the holders of the Series C Preferred Stock will be entitled to receive upon conversion of the Series C Preferred Stock the same kind and amount of securities, cash or property which the holders would have received had they converted the Series C Preferred Stock immediately prior to such fundamental transaction. Any successor to us or surviving entity must assume the obligations under the Series C Certificate of Designation with respect to the Series C Preferred Stock.

Stock Options

As of December 27, 2022, we had outstanding options to purchase an aggregate of 21,376 shares of our common stock, with a weighted-average exercise price of approximately $294.00 per share.

Restricted Stock Units

As of December 27, 2022, we had 4,524 restricted stock units outstanding.

Table of Contents

Warrants

As of December 27, 2022, we had outstanding warrants to purchase an aggregate of 206,819 shares of our common stock at a weighted average-exercise price of approximately $213.28 per share with expiration dates ranging from 2023 to 2028.

We have agreed to file a registration statement providing for the resale by the purchaser of the warrants issued in a private placement on November 9, 2022 and to keep such registration statement effective at all times until the purchaser no longer owns any such warrants or shares of common stock issuable upon exercise thereof.

Anti-Takeover Provisions

The provisions of Delaware law, our restated certificate of incorporation and our restated bylaws could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below, may have the effect of discouraging takeover bids. They are also designed, in part, to encourage persons seeking to acquire control of us to negotiate first with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly or unsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

Delaware law

We are subject to the provisions of Section 203 of the DGCL, or Section 203, regulating corporate takeovers. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date on which the person became an interested stockholder unless:

Generally, a business combination includes a merger, asset or stock sale, or other transaction or series of transactions together resulting in a financial benefit to the interested stockholder. An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate that Section 203 may also discourage attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

Restated certificate of incorporation and restated bylaws provisions

Our restated certificate of incorporation and our restated bylaws include a number of provisions that could deter hostile takeovers or delay or prevent changes in control of our company, including the following:

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

Overview

We are the premier global weight-loss solutions company, offering an integrated portfolio of proven products and services that manage and treat obesity and associated metabolic disease. Our primary operations are in the following geographical areas: United States, Australia and certain European and Middle Eastern countries. Our current portfolio includes the Lap-Band Adjustable Gastric Banding System, the ReShapeCare virtual health coaching program, the ReShape Marketplace, the Obalon Balloon System, and the DBSN device, a technology under development as a new treatment for type 2 diabetes mellitus. There has been no revenue recorded for the Obalon Balloon System which was acquired, and there has been no revenue recorded for the DBSN device as these products are still in the development stage.

Recent Developments

On January 19, 2021, the Company entered into the fourth amendment to the credit agreement that increased the amount available under the delayed draw term loans by $1.0 million, of which all funds were received upfront and used for the escrow fund securing the termination fee under the Merger Agreement. The maturity date of the loans under the credit agreement, including those under the amendment was March 31, 2021, all of which has subsequently been paid in full.

On March 1, 2021, the Company received confirmation from the SBA that the PPP Loan was forgiven in full including all interest incurred.

The Company received approximately $45.5 million in proceeds, of which $10.8 million was used to pay off the credit agreement, including $10.5 million of debt and $0.3 million of accrued interest. The remaining proceeds will be used for working capital and general corporate purposes.

On October 12, 2021, the Company announced the launch of a multi-platform consumer advertising campaign utilizing national television, print, social media, and public relations to market the Next-Generation Lap-Band program with available aftercare supported through ReShapeCare, the virtual health coaching platform to create consumer awareness and increase patient demand.

Results of Operations

The following table sets forth certain data from our operating results from the years ended December 31, 2021 and 2020, expressed as percentages of net revenue (in thousands):

​

Non-GAAP Disclosures

In addition to the financial information prepared in conformity with GAAP, we provide certain historical non-GAAP financial information. Management believes that these non-GAAP financial measures assist investors in making comparisons of period-to-period operating results and that, in some respects, these non-GAAP financial measures are more indicative of the Company’s ongoing core operating performance than their GAAP equivalents.

Management believes that the presentation of this non-GAAP financial information provides investors with greater transparency and facilitates comparison of operating results across a broad spectrum of companies with varying capital structures, compensation strategies, derivative instruments, and amortization methods, which provides a more complete understanding of our financial performance, competitive position, and prospects for the future. However, the non-GAAP financial measures presented in this prospectus have certain limitations in that they do not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, the non-GAAP financial measures presented by the Company may be different from similarly named non-GAAP financial measures used by other companies.

Adjusted EBITDA

Management uses Adjusted EBITDA in its evaluation of the Company’s core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Adjusted EBITDA is defined as net loss before interest, taxes, depreciation and amortization, stock-based compensation, changes in fair value of liability warrants and other one-time costs. Management uses Adjusted EBITDA in its evaluation of the Company’s core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Therefore, investors should consider non-GAAP financial measures in addition to, and not as a substitute for, or

Comparison of Results of Operations

Revenue.    The following table summarizes our net revenue by geographic location based on the location of customers for the years ended December 31, 2021 and 2020, as well as the percentage by location of total revenue and the amount of change and percentage of change (dollars in thousands):

​

Revenue totaled $13.6 million for the year ended December 31, 2021, compared to $11.3 million for the year ended December 31, 2020. The primary reason for the increase of $2.3 million, or 20.4%, is due to a $2.0 million increase in sales for the United States, and a $0.3 million increase internationally. The increase in total revenue is primarily due to lessened COVID 19 pandemic restrictions for elective surgeries in 2021 as compared to 2020. There has also been a rise in obesity awareness due to the complications associated with COVID 19 for obesity, and the Company has increased its overall sales and marketing efforts, which has resulted in increased sales. We did see a slight decrease in sales during the fourth quarter of 2021, due to the rise of the Delta and Omicron variants, and the associated restrictions.

Cost of Goods Sold and Gross Profit:    The following table summarizes our cost of goods sold and gross profit for the years ended December 31, 2021 and 2020, as well as percentage of total revenue and the amount of change and percentage of change (dollars in thousands):

​

Gross profit.    Gross profit for the year ended December 31, 2021, was $8.3 million, compared to $6.3 million for the year ended December 31, 2020, an increase of $2.0 million or 33.3%. Gross profit as a percentage of revenue for the year ended December 31, 2021, was 61.4% compared to 55.4% for the same period in 2020. The increase in gross profit margin is primarily due to increased volume, as revenue increased by 20.4%, reduced period expenses, and improved product mix with higher domestic sales as

a percentage of revenue, which have a higher gross profit margin than international sales. We have also begun to realize significant cost of goods savings by moving our manufacturing from Costa Rica to a new supplier in the United States.

Operating Expenses:    The following table summarizes our operating expenses for the years ended December 31, 2021 and 2020, as well as the percentage of total revenue, and the amount of changes and percentage of change (dollars in thousands):

​

Total operating expenses increased by $46.1 million, or 246.4%, due primarily to an impairment charge of $28.8 million, an increase in stock-based compensation of $11.4 million and an increase in general and administrative expenses related to the merger with Obalon of $2.3 million. After the Obalon merger, and subsequent listing on the Nasdaq, the Company issued either restricted stock units or stock options to all employees and non-employee directors of the Company, its first grant since 2017. The vesting schedules for these grants were retroactive to hire dates, so there was a catch-up expense of $8.9 million. Due to this catch-up, the Company expects for stock-based compensation expense to normalize going forward. The Company has begun focusing on increased brand recognition through improved marketing strategies, including television and print advertisements, and social media presence which has increased our overall sales and marketing expenses. As previously disclosed, the Company announced the launch of a multi-platform consumer advertising campaign utilizing national television, print, social media and public relations during the fourth quarter of 2021.

Sales and Marketing Expense.    Sales and marketing expenses for the year ended December 31, 2021, increased by $4.5 million, or 95.2%, to $9.2 million, compared to $4.7 million for the year ended December 31, 2020. The increase is primarily due to an increase in advertising and marketing costs of $2.5 million, as the Company launched its direct to consumer campaign, and increased its social media presence. In addition, we had an increase in stock-based compensation expense of $1.2 million, as during the third quarter of 2021, the Company issued both RSUs and stock options containing a look back provision to begin vesting at the one-year anniversary of the date of employment, resulting in an expense of $0.9 million at the time the awards were granted. Additionally, payroll related expenditures increased by $0.4 million as the Company strengthened its commercial organization and commissions increased by $0.2 million from higher revenue compared to the prior year. The Company also had an increase in software costs of $0.2 million. These increases were minimally offset by a decrease of $0.2 million in consulting fees. The Company expects to continue devoting more resources toward sales and marketing, particularly through our national direct to consumer campaign, and so we expect total Sales and Marketing expenses to increase for 2022.

General and Administrative Expense.    General and administrative expenses for the year ended December 31, 2021, increased by $13.9 million, or 131.9%, to $24.4 million, compared to $10.5 million for the year ended December 31, 2020. The increase is primarily due to an increase of $8.9 million in stock-based compensation expense, as during the third quarter of 2021, the Company issued both RSUs and stock options containing a look back provision to begin vesting at the one-year anniversary of the date of employment, resulting in an expense of $6.8 million at the time the awards were granted. In addition, the Company had increases in audit, consulting and other professional services of $3.2 million, of which $2.3 million was directly related to the merger with Obalon, an increase in payroll related expenses of $1.0 million, including a $0.7 million increase in bonus fees, an increase in legal and patent related fees of $0.4 million, an increase in rent and facilities of $0.3 million due to the facilities assumed from the merger with Obalon, and an increase in insurance fees of $0.1 million. These increases were partially offset by a decrease in bad debt expense of $0.2 million, as the Company continues to focus on collections.

Research and Development Expense.    Research and development expenses for the year ended December 31, 2021, decreased by $1.0 million, or 27.9%, to $2.5 million, compared to $3.5 million for the year ended December 31, 2020. The decrease is primarily due to a $2.2 million reduction in consulting, and clinical trial expenses as a result of a slowdown in clinical trials for the ReShape Vest due to the COVID 19 pandemic, and a reduction in payroll expenses of $0.1 million. This decrease was offset by an increase of $1.3 million in stock-based compensation expense, as during the third quarter of 2021, the Company issued both RSUs and stock options containing a look back provision to begin vesting at the one-year anniversary of the date of employment, resulting in an expense of $1.2 million at the time the awards were granted.

Loss on Impairment of Intangible Assets and Goodwill. The Company incurred two impairment charges totaling $28.8 million during the year ended December 31, 2021. The Company recorded a goodwill impairment charge of $21.6 million due to a reduction in our market capitalization at year-end. In addition, an impairment charge of $7.2 million was recorded, due to a reduction in our market capitalization coupled with the effects of the delays in the ReShape Vest clinical trials from the COVID-19 pandemic thus reducing the near-term future net cash flows. For further details regarding the impairment charges, see Note 7 to our consolidated financial statements included in this prospectus. During the year ended December 31, 2020, the Company did not have an impairment of intangible assets.

Net Interest Expense.    Net interest expense for the year ended December 31, 2021, decreased by $1.2 million, to $0.8 million, compared to $2.0 million, for the year ended December 31, 2020. The primary reason for the decrease is due to the Company paying off the credit agreement during the second quarter of 2021 and the forgiveness of the PPP loan including accrued interest during the first quarter of 2021.

Warrant Expense. Warrant expense was $2.8 million for the year ended December 31, 2021. The warrant expense relates to the issuance of warrants and common stock in connection with the exchange agreement entered with an investor that held Obalon warrants and exercised the fundamental transaction provision of their warrants. There was no warrant expenses for the year ended December 31, 2020.

Loss on Extinguishment of Debt.   Loss on extinguishment of debt, net for the year ended December 31, 2021, was $2.1 million, which consisted of losses of $3.0 million related to the fair value of the warrants issued in connection with the January 19, 2021, credit agreement amendments and $0.1 million related to the early payment of the debt. These losses were offset by a $1.0 million gain on the full extinguishment of our PPP loan, as we received official confirmation of forgiveness on March 1, 2021. The Company recognized a loss on extinguishment of debt for the year ended December 31, 2020, of $7.7 million, related to the fair value of the warrants issued in connection with the third and fourth amendments of the credit agreement and discounts related to the amendments.

Liquidity and Capital Resources

We have financed our operations to date principally through the sale of equity securities and debt financings. During the years ended December 31, 2021 and 2020, we received proceeds of $45.6 million and $0.7 million, respectively, from exercises of warrants by institutional investors, and $1.0 million and $9.5 million, respectively, from the credit agreement with an institutional investor. As of December 31, 2021, we had $22.8 million of cash and cash equivalents, which includes $5.2 million of cash received in connection with the merger with Obalon and $50 thousand of restricted cash. During March of 2021, the Company received confirmation from the SBA that the PPP Loan was forgiven in full including all interest incurred and in June of 2021, the credit agreement was paid in full.
