Basis of Presentation
Basis of Presentation	(1) Basis of Presentation The accompanying interim condensed consolidated financial statements and related disclosures of Reshape Lifesciences Inc. (the “Company” or “ReShape”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") and should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, filed on March 11, 2021. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") have been condensed or omitted. In the opinion of management, the interim consolidated condensed financial statements reflect all adjustments considered necessary for a fair statement of the interim periods. All such adjustments are of a normal, recurring nature. The results of operations for the interim periods are not necessarily indicative of the results of operations to be expected for the full year. Acquisition The Company accounts for business combinations in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business generally being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Transaction costs associated with business combinations are expensed as incurred and are included in acquisition related costs in the consolidated statements of operations. The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets and liabilities. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates Upon completion of the business combination on June 15, 2021 with Obalon Therapeurtics, Inc. (“Obalon”), the transaction was treated as a “reverse acquisition” for financial accounting purposes. As a result of the controlling interest of the former shareholders of ReShape, for financial statement reporting and accounting purposes, ReShape was considered the acquirer under the acquisition method of accounting in accordance with the FASB Accounting Standards Codification (“ASC”) 805-10-55. The reverse acquisition is deemed a capital transaction in substance whereas the historical assets and liabilities of Obalon before the business combination were replaced with the historical financial statements of ReShape in all future filings with the SEC. Goodwill and Long-Lived Assets Goodwill represents the excess of the cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. Indefinite-lived intangible assets relate to in-process research and development ("IPR&D") acquired in business combinations. The estimated fair values of IPR&D projects acquired in a business combination which have not reached technological feasibility are capitalized and accounted for as indefinite-lived intangible assets until completion or abandonment of the projects. In accordance with guidance within Financial Accounting Standards Board (FASB) Accounting Standards Codification (“ASC”) 350 “Intangibles - Goodwill and Other,” goodwill and identifiable intangible assets with indefinite lives are not subject to amortization but must be evaluated for impairment. We evaluate long-lived assets, including finite-lived intangible assets, for impairment by comparison of the carrying amounts to future net undiscounted cash flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value or estimates of future discounted cash flows. For goodwill and indefinite-lived intangible assets, in-process research and development, we review for impairment annually and upon the occurrence of certain events as required by Accounting Standards Codification (“ASC”) Topic 350, “Intangibles — Goodwill and Other.” Goodwill and indefinite-lived intangible assets are tested at least annually for impairment and more frequently if events or changes in circumstances indicate that the asset might be impaired. We review goodwill for impairment by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If we are able to determine that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we would conclude that goodwill is not impaired. If the carrying amount of a reporting unit is zero or negative, the second step of the impairment test is performed to measure the amount of impairment loss, if any, when it is more likely than not that a goodwill impairment exists. The Company did not record any impairment loss for goodwill or indefinite-lived intangible assets for the three and six months ended June 30, 2021 and 2020. Fair Value of Financial Instruments The carrying amounts of cash equivalents, accounts receivable, accounts payable and certain accrued and other liabilities approximate fair value due to their short-term maturities. Refer to Note 5 regarding the fair value of debt instruments and Note 9 regarding fair value measurements and inputs of warrants. Net Loss Per Share The following table sets forth the potential shares of common stock that are not included in the calculation of diluted net loss per share because to do so would be anti-dilutive as of the end of each period presented: June 30, 2021 2020 Stock options 256,881 46 Convertible preferred stock 742 1,288 Warrants 6,181,997 8,283,447 Recent Accounting Pronouncements New accounting standards adopted by the Company in 2021 are discussed below or in the related notes, where appropriate. In December 2019, the FASB issued authoritative guidance intended to simplify the accounting for income taxes: ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This guidance eliminates certain exceptions to the general approach to the income tax accounting model and adds new guidance to reduce the complexity in accounting for income taxes. The adoption of this guidance on January 1, 2021 did not have a material impact on the Company’s consolidated financial statements. New accounting standards not yet adopted are discussed below. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt – Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging Contracts in Entity’s Own Equity (Subtopic 815-40). In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326)

Liquidity and Management's Plans	Jun. 30, 2021
Liquidity and Management's Plans
Liquidity and Management's Plans	(2) Liquidity and Management’s Plans As of June 30, 2021, the Company had net working capital of approximately $5.1 million, primarily due to the cash and cash equivalents of $40.2 million, which includes $5.2 million obtained in connection with the acquisition of Obalon, and $17.7 million of deferred issuance costs offset by an accrual of $43.2 million due to the timing of the issuance of the common shares in connection with the equity transaction. For further details see notes 8 and 9 below. The $17.7 million deferred issuance costs and the $43.2 million share abeyance accrual will be reclassed to equity for the third quarter ending September 30, 2021 as those shares were issued in July 2021. The Company’s principal source of liquidity as of June 30, 2021 consisted of approximately $40.2 million of cash and cash equivalents and restricted cash, and $3.4 million of accounts receivable. In addition, the Company had its PPP loan and accrued interest forgiven in full, and paid back the $10.5 million of debt with an institutional investor. For further details, see Note 5. The Company’s anticipated operations include plans to (i) manufacture, and promote the sales and operations of the LAP-BAND ® care TM care COVID-19 Risk and Uncertainties and CARES Act On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the “COVID-19 outbreak”) and the risks to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally and on March 13, 2020, the United States declared a national emergency with respect to the coronavirus outbreak. This outbreak has severely impacted global economic activity, and many countries and many states in the United States have reacted to the outbreak by instituting quarantines, mandating business and school closures and restricting travel. These mandated business closures have at times included the cessation of non-elective surgeries in Australia, Europe and the United States for all but emergency procedures. As a result of these mandates, on April 16, 2020, the Company implemented various short-term cost reductions and cash flow improvement actions, such as reducing the compensation for executives, management and key employees and decreasing operating expenses where possible. In addition, the Company identified temporary headcount reductions and made the decision to furlough a portion of its workforce. During the second quarter of 2020, the mandated closures began to ease in many areas throughout the world and within the United States. As a result of this, elective surgeries started back up again through various parts of the world, which led to improved sales progressing through the third quarter. Even after the COVID-19 outbreak has subsided, the Company may continue to experience materially adverse impact on its financial condition and results of operation. Additionally, on June 15, 2020, the Company ended the temporary pay reductions and the furloughed employees returned to work. The full impact of the COVID-19 outbreak continues to evolve and it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the impact of the global situation on the Company’s financial condition, liquidity, operations, suppliers, industry, and workforce and has taken actions to mitigate the impact including among other things, temporary reductions in pay, and furloughs of certain positions along with deferrals in payment for cash preservation. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak on its results of operations, financial condition, or liquidity for fiscal year 2021. On March 27, 2020, President Trump signed into law the “Coronavirus Aid, Relief, and Economic Security (CARES) Act.” The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act established the Paycheck Protection Program (“PPP”) under which the Company received a PPP loan described in more detail in Note 5 below. On February 3, 2021, the Company submitted the application for PPP loan forgiveness according to the terms and conditions of the SBA’s Loan Forgiveness Application (Revised June 24, 2002). On March 1, 2021, the Company received confirmation from the SBA that, the PPP Loan had been forgiven in full including all interest incurred. For further details, see Note 5.

As part of the application for these funds, the Company in good faith, has certified that the current economic uncertainty made the loan request necessary to support the ongoing operations of the Company. This certification further requires the Company to take into account our current business activity and our ability to access other sources of liquidity sufficient to support ongoing operations in a manner that is not significantly detrimental to the business. Under this program, the Company received proceeds of $1.0 million from the PPP Loan. In accordance with the requirements of the PPP, the Company intends to use proceeds from the PPP Loan primarily for payroll costs, rent and utilities. The PPP Loan has a 1.00% interest rate per annum, matures on April 24, 2022 and is subject to the terms and conditions applicable to loans administered by the SBA under the PPP. On February 23, 2021, the Company submitted the application for PPP loan forgiveness, in accordance with the terms and conditions of the SBA’s Loan Forgiveness Application (revised June 24, 2020). On March 1, 2021, the Company received confirmation from the SBA that the PPP Loan was forgiven in full including all interest incurred, which resulted in a gain on debt extinguishment of $1.0 million, during the six months ended June 30, 2021. Under the provisions of the CARES Act, the Company is eligible for a refundable employee retention credit subject to certain criteria. The Company recognized a $0.2 million employee retention credit during the three months ended June 30, 2021, and $0.5 million for the six months ended June 30, 2021. Credit Agreement On March 25, 2020, the Company executed a credit agreement up to $3.5 million, with an institutional investor (the “Lender”), who holds warrants in connection with the June 2019 and September 2019 transactions. On the day of closing, the Company received $2.5 million and the additional $1.0 million may be drawn from time to time 30 days after the closing date but prior to five months after the closing date, in $500 thousand increments per draw. On June 23, 2020, the Company made the first additional draw of $500 thousand and on July 29, 2020 the second $500 thousand draw was made. As required by the terms of this credit agreement, the lender exercised its warrants to purchase an aggregate of 5,085,834 shares of common stock with a current exercise price of $0.12 per warrant on April 15, 2020, in which the Company received net proceeds of $0.6 million. In addition, the Company issued to the lender 1,200,000 Series G warrants to purchase an aggregate of 1,200,000 shares of common stock. As an inducement to the Lender to enter into the amendment and make the additional loans contemplated thereby, the Company issued to the Lender an additional 1,200,000 Series G warrants dated September 14, 2020 to purchase an aggregate of 1,200,000 shares of common stock. The original Series G warrants were valued using the relative fair value basis and the amount was recorded as part of the debt issuance costs, see Note 9 for additional details. On September 14, 2020, the Company and the Lender entered into an amendment to the credit agreement that increased the amount available under delayed draw term loans by $2.0 million. The Company borrowed $1.0 million of the available amount immediately and the remaining $1.0 million will be available in increments of least $500 thousand with at least 30 days between borrowings and issued an additional 1,200,000 Series G Warrants. The Company evaluated the accounting related to the amendment and in conjunction with the warrants issued. Based on this analysis the Company determined the agreements are substantially different and extinguished the original credit agreement and recorded the amended credit agreement as a new debt at a fair value of $3.9 million. As a result in 2020, the Company recorded a debt discount of approximately $0.6 million and a $2.4 million loss on extinguishment of debt which is comprised of the fair value of the warrants and unamortized debt issuance cost with the original credit agreement, offset by the debt discount. Pursuant to the amendment of the credit agreement, the maturity date of the loans was March 31, 2021 and the loans bear interest at LIBOR plus 2.5%. On December 16, 2020, the Company and the Lender entered into the third amendment to the credit agreement that increased the amount available under delayed draw term loans by an additional $4.0 million. The Company borrowed the entire $4.0 million of the available amount immediately and issued an additional 4,000,000 Series G Warrants. The Company evaluated the accounting related to the amendment and in conjunction with the warrants issued. Based on this analysis the Company determined the agreements are substantially different and extinguished the original credit agreement and recorded the amended credit agreement as a new debt at a fair value of $8.9 million. As a result in 2020, the Company recorded a debt discount of approximately $0.6 million and a $5.3 million loss on extinguishment of debt which is comprised of the fair value of the warrants and unamortized debt discount cost with the original credit agreement, offset by the debt discount related to the new debt. At December 31, 2020 there was approximately $0.5 million of unamortized debt discount. Pursuant to the amendment of the credit agreement, the maturity date of the loan was March 31, 2021 and the loans bear interest at LIBOR plus 2.5%. On January 19, 2021, the Company and the Lender entered into an amendment to the credit agreement that increased the amount available under delayed draw term loans by $1.0 million, which was used to fund the $1.0 million escrow fund securing the termination fee under the Merger Agreement and issued an additional 1,000,000 Series G Warrants. The Company evaluated the accounting related to the amendment and in conjunction with the warrants issued. Based on this analysis the Company determined the agreements are substantially different and extinguished the original credit agreement and recorded the amended credit agreement as a new debt at a fair value of $10.0 million. As a result, during the three months ended March 31, 2021, the Company recorded a debt discount of approximately $0.5 million and a $3.0 million loss on extinguishment of debt, which is comprised of the fair value of the warrants and unamortized debt issuance cost with the original credit agreement, offset by the debt discount. At March 31, 2021, there was approximately $0.1 million of unamortized debt discount. Pursuant to the amendment of the credit agreement, the maturity date of the loans are March 31, 2021 and the loans bear interest at LIBOR plus 2.5%. On March 10, 2021, the Company and the Lender entered into an amendment to the credit agreement that extended the maturity date from March 31, 2021 to March 31, 2022. The Company has accounted for this amendment as a debt modification. The associated unamortized debt discount on the January 19, 2021 amendment of $0.1 million will be amortized as interest expense over the term of the amended credit agreement. On June 28, 2021, the Company entered into a warrant exercise agreement with existing accredited investors, including the Lender, to exercise certain outstanding warrants, for further details on this transaction see Note 9. The Company used some of the proceeds from this transaction to pay off the $10.5 million of debt outstanding under the credit agreement. At June 30, 2021, there was no outstanding amount under the credit agreement.

Acquisition	(7) Acquisition On June 15, 2021, the Company completed the previously announced merger with Obalon, which was treated as a reverse acquisition for accounting purposes, for an aggregate purchase price of $30.6 million. This includes the issuance of 3,340,035 shares of common stock valued at $30.6 million at the closing market price of the day of merger and the cancellation of 2,680,301 shares of common stock. As a result of the controlling interest of the former shareholders of ReShape, for financial statement reporting and accounting purposes, ReShape was considered the acquirer under the acquisition method of accounting in accordance with ASC 805-10-55. The reverse acquisition is deemed a capital transaction in substance whereas the historical assets and liabilities of Obalon before the business combination were replaced with the historical financial statements of ReShape in all future filings with the SEC. Acquisition related costs of $2.3 million were recorded in general and administrative expense for the three and six months of June 30, 2021. Tangible and intangible assets acquired were recorded based on their estimated fair values at the acquisition date. The excess of the purchase price over the fair value of the net assets acquired was recorded to goodwill. The following table summarizes the preliminary fair values of the assets acquired and liabilities assumed, primarily related to inventory, developed technology, goodwill (including the deductibility for tax purposes) and income tax related accruals: Current assets $ 6,348 Property and equipment, net 848 Right-of-use assets 335 Other assets 1,898 Goodwill 21,623 Developed technology 2,730 Liabilities assumed (3,220) Total purchase price 30,562 Less: cash acquired (5,207) Total purchase price, net of cash acquired $ 25,355 The size of the Obalon acquisition necessitates use of the allowable measurement period to adequately analyze all the factors used in establishing the asset and liability fair values as of the acquisition date. The preliminary acquisition accounting is based upon the Company’s estimates of fair value. The primary areas of the preliminary acquisition accounting that are not yet finalized include the following: (i) finalizing the review and valuation of property and equipment (including the models, key assumptions, estimates and inputs used), (ii) finalizing the review and valuation of related intangible assets (including key assumptions, inputs and estimates), (iii) finalizing the valuation of certain in-place contracts or contractual relationships (including but not limited to leases), (iv) finalizing our review of certain assets acquired and liabilities assumed, (v) finalizing our estimate of the impact of acquisition accounting on deferred income taxes or liabilities. As the initial acquisition accounting is based on our preliminary assessments, actual values may differ (possibly materially) when final information becomes available that differs from our current estimates. We will continue to evaluate these items, until they are satisfactorily resolved and adjust our acquisition accounting accordingly, within the allowable measurement period (not to exceed one year from the date of acquisition), as defined by ASC 805. Goodwill includes expected synergies and other benefits the Company believes will result from the acquisition. The developed technology has been capitalized at fair value as an intangible asset with an estimated life of 15 years. The developed technology was determined using the income approach. This approach determines fair value based on cash flow projections which are discounted to present value using a risk-adjusted rate of return, using nonrecurring Level 3 inputs. The discount rate used was 22.0%.

Income Taxes
Income Taxes	(11) Income Taxes The Company’s tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter the Company updates its estimate of the annual effective tax rate. The Company’s quarter tax provision, and quarterly estimate of annual effective tax rate, are subject to significant volatility due to several factors, including the Company’s ability to accurately predict pre-tax income and loss. During the three and six months ended June 30, 2021, a $28 thousand and $53 thousand, respectively, tax expense was recorded, primarily due to projected income in Australia and Netherlands. During the three and six months ended June 30, 2020, a $50 thousand and $68 thousand, respectively, tax benefit was recorded, primarily related to projected losses in Australia. In assessing the realization of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during periods in which those temporary differences become deductible. Based on the level of historical losses, projections of losses in future periods and potential limitations pursuant to changes in ownership under Internal Revenue Code (“IRC”) Section 382, the Company provided a valuation allowance at both March 31, 2021 and December 31, 2020. Additionally, as stated above, upon completion of the business combination on June 16, 2021 with Obalon Therapeutics, Inc. (“Obalon”), the transaction was treated as a “reverse acquisition” for financial accounting purposes. Due to the fact that more than 50% of the former ReShape shareholders retained ownership in the newly consolidated group, it is intended to be treated as a reverse acquisition for tax purposes as well.

Acquisition	Acquisition The Company accounts for business combinations in accordance with Accounting Standards Codification (“ASC”) 805, Business Combinations. The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business generally being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Transaction costs associated with business combinations are expensed as incurred and are included in acquisition related costs in the consolidated statements of operations. The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets and liabilities. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates Upon completion of the business combination on June 15, 2021 with Obalon Therapeurtics, Inc. (“Obalon”), the transaction was treated as a “reverse acquisition” for financial accounting purposes. As a result of the controlling interest of the former shareholders of ReShape, for financial statement reporting and accounting purposes, ReShape was considered the acquirer under the acquisition method of accounting in accordance with the FASB Accounting Standards Codification (“ASC”) 805-10-55. The reverse acquisition is deemed a capital transaction in substance whereas the historical assets and liabilities of Obalon before the business combination were replaced with the historical financial statements of ReShape in all future filings with the SEC.
Goodwill and Long-Lived Assets	Goodwill and Long-Lived Assets Goodwill represents the excess of the cost of an acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed in a business combination. Indefinite-lived intangible assets relate to in-process research and development ("IPR&D") acquired in business combinations. The estimated fair values of IPR&D projects acquired in a business combination which have not reached technological feasibility are capitalized and accounted for as indefinite-lived intangible assets until completion or abandonment of the projects. In accordance with guidance within Financial Accounting Standards Board (FASB) Accounting Standards Codification (“ASC”) 350 “Intangibles - Goodwill and Other,” goodwill and identifiable intangible assets with indefinite lives are not subject to amortization but must be evaluated for impairment. We evaluate long-lived assets, including finite-lived intangible assets, for impairment by comparison of the carrying amounts to future net undiscounted cash flows expected to be generated by such assets when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Should an impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s fair value or estimates of future discounted cash flows. For goodwill and indefinite-lived intangible assets, in-process research and development, we review for impairment annually and upon the occurrence of certain events as required by Accounting Standards Codification (“ASC”) Topic 350, “Intangibles — Goodwill and Other.” Goodwill and indefinite-lived intangible assets are tested at least annually for impairment and more frequently if events or changes in circumstances indicate that the asset might be impaired. We review goodwill for impairment by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If we are able to determine that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, we would conclude that goodwill is not impaired. If the carrying amount of a reporting unit is zero or negative, the second step of the impairment test is performed to measure the amount of impairment loss, if any, when it is more likely than not that a goodwill impairment exists. The Company did not record any impairment loss for goodwill or indefinite-lived intangible assets for the three and six months ended June 30, 2021 and 2020.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of cash equivalents, accounts receivable, accounts payable and certain accrued and other liabilities approximate fair value due to their short-term maturities. Refer to Note 5 regarding the fair value of debt instruments and Note 9 regarding fair value measurements and inputs of warrants.

Recent Accounting Pronouncements	Recent Accounting Pronouncements New accounting standards adopted by the Company in 2021 are discussed below or in the related notes, where appropriate. In December 2019, the FASB issued authoritative guidance intended to simplify the accounting for income taxes: ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This guidance eliminates certain exceptions to the general approach to the income tax accounting model and adds new guidance to reduce the complexity in accounting for income taxes. The adoption of this guidance on January 1, 2021 did not have a material impact on the Company’s consolidated financial statements. New accounting standards not yet adopted are discussed below. In May 2021, the FASB issued ASU No. 2021-04, Earnings Per Share (Topic 260), Debt – Modifications and Extinguishments (Subtopic 470-50), Compensation – Stock Compensation (Topic 718), and Derivatives and Hedging Contracts in Entity’s Own Equity (Subtopic 815-40). In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326)
