Organization and Description of Business
Organization and Description of Business	Note 1 – Organization and Description of Business Ideal Power Inc. (the “Company”) was incorporated in Texas on May 17, 2007 under the name Ideal Power Converters, Inc. The Company changed its name to Ideal Power Inc. on July 8, 2013 and re-incorporated in Delaware on July 15, 2013. The Company is located in Austin, Texas. Prior to 2019, the Company developed power conversion solutions with a focus on solar and storage, microgrid and stand-alone energy storage applications. The principal products of the Company were 30‑kilowatt power conversion systems, including 2‑port and multi-port products. On April 16, 2018, the Company realigned into two operating divisions: Power Conversion Systems, to continue the commercialization of its PPSA™ technology, and B-TRAN, to develop its Bi-directional bi-polar junction TRANsistor (B-TRAN™) solid state switch technology. On January 2, 2019, the Board of Directors of the Company (the “Board”) approved a strategic shift to focus on the further development and commercialization of its B-TRAN™ technology and a plan to suspend further power converter system development and sales while the Company located a buyer for its power conversion systems division. On September 19, 2019, the Company closed on the sale of its power conversion systems division and is now solely focused on the further development and commercialization of its B-TRAN(TM) technology. See Note 3. Since its inception, the Company has generated limited revenues from the sale of products and has financed its research and development efforts and operations primarily through the sale of common stock. The Company’s continued operations are dependent upon its ability to obtain adequate sources of funding through future revenues, equity and debt financing, co-development agreements, government grants, sale or licensing of developed intellectual property or other alternatives.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for Form 10-Q. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“U.S.GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Balance Sheet at December 31, 2018 has been derived from the Company’s audited financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on April 1, 2019. In the opinion of management, these financial statements reflect all normal recurring, and other adjustments, necessary for a fair presentation. These financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year or any other future periods. Reverse Stock Split On August 15, 2019, the Company effected a reverse stock split of the outstanding shares of its common stock by a ratio of one-for-ten, and its common stock began trading on the Nasdaq Capital Market on a split-adjusted basis on August 20, 2019. The par value of the Company’s common stock remained unchanged at $0.001 per share after the reverse stock split. All share amounts, per share data, share prices, exercise prices and conversion rates set forth in these notes and the accompanying unaudited condensed financial statements have, where applicable, been adjusted retroactively to reflect the reverse stock split. See Note 7. Liquidity and Going Concern The Company had a net loss of $3.1 million and used $2.4 million of cash in operating activities for the nine months ended September 30, 2019. At September 30, 2019, the Company had net working capital of $0.4 million and the Company’s principal source of liquidity consisted of $0.8 million of cash and cash equivalents. The Company’s cash and cash equivalent balance at September 30, 2019 relative to its estimate of future operating cash requirements led to substantial doubt about the ability of the Company to continue as a going concern. The Company’s independent registered public accounting firm, in its report on the Company’s 2018 financial statements, raised substantial doubt about the Company’s ability to continue as a going concern. On November 13, 2019, the Company completed a private placement of the Company’s common stock and warrants to purchase common stock for aggregate gross proceeds of $3.5 million and estimated net proceeds of $3.1 million, thereby alleviating the substantial doubt about the Company’s ability to continue as a going concern for at least the next twelve months from the date of issuance of these financial statements. See Note 11. The accompanying condensed financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The ability of the Company to continue as a going concern is dependent on its ability to raise additional capital and to develop profitable operations through implementation of its current business initiatives, however, there can be no assurances that the Company will be able to raise additional capital on favorable terms, or at all, or develop profitable operations. The accompanying condensed financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern. Recently Adopted Standards In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet. Most prominent among the amendments is the recognition of assets and liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. Under the new standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted this standard effective January 1, 2019. Upon adoption, the Company recognized its lease commitment as a lease liability and right-of-use asset. For more details regarding the lease commitment, see Note 5. Recent Accounting Pronouncements Management does not believe that any other recently issued, but not yet effective, accounting standard, if adopted, would have a material impact on the Company’s financial statements.

Sale of Power Conversion System

Sale of Power Conversion Systems Division
Sale of Power Conversion Systems Division	Note 3 – Sale of Power Conversion Systems Division On January 2, 2019, the Board approved a strategic shift to focus on the commercialization of its B-TRAN™ technology and a plan to suspend further power converter system development and sales while the Company located a buyer for its power conversion systems division. On January 4, 2019, the Company implemented a reduction-in-force in connection with this exit activity and recognized an expense of $92,600 in involuntary termination benefits. The Company’s power conversion system division, a component supplier to energy storage system integrators, had not achieved the necessary scale to generate positive cash flows. As the division was dependent on the ability of its customers to scale in the small commercial and industrial segment of the energy storage market and based on the sales forecasts and commitments provided by these customers, the Company did not expect its power conversion systems division to scale sufficiently in the short term, requiring an inflow of additional capital for the business. As such, the decision was made to exit the power conversion systems business and sell the division and the Company’s PPSA™ technology and focus on the Company’s B-TRAN™ technology. As a result, the assets held for sale and discontinued operations criteria were met and the Company’s financial statements are presented in accordance with ASC 205. Under ASC 205‑20‑45‑10, during the period in which a component meets the assets held for sale and discontinued operations criteria, an entity must present the assets and liabilities of the discontinued operation separately in the asset and liability sections of the balance sheet for the comparative reporting periods. The prior period balance sheet should be reclassified for the held for sale items. For income statements, the current and prior periods should report the results of operations of the component in discontinued operations when comparative income statements are presented. On September 19, 2019, the Company closed on the sale of its power conversion systems division to CE+T Energy Solutions, Inc. (“CE+T Energy”). The consideration consisted of $200,000 in cash, received at closing, and 50 shares of CE+T Energy’s common stock, to be issued within 90 days of closing, which represented a 5% ownership interest in CE+T Energy as of the closing date. The Company did not record any value of the equity consideration obtained in the sale as there is not currently a market for such shares and the Company does not have access to current financial information and future financial projections of CE+T Energy. CE+T Energy also assumed certain liabilities of the power conversion systems division in connection with the sale. The net cash proceeds from the sale were $23,587. As a result of the sale, the financial statements for the period ended September 30, 2019 do not include assets held for sale. The following is a reconciliation of the carrying amounts of major classes of assets and liabilities of the discontinued operations to assets and liabilities held for sale: December 31, 2018 Accounts receivable, net $ 270,768 Inventories, net 131,342 Prepayments and other current assets 22,322 Property and equipment, net 329,738 Intangible assets, net 342,153 Current assets held for sale (1) $ 1,096,323 Accounts payable $ 356,113 Accrued expenses 521,642 Current liabilities held for sale $ 877,755 (1) The assets of the discontinued operations classified as held for sale are classified as current on the December 31, 2018 balance sheet as it was deemed probable that the sale would occur and proceeds would be collected within one year. The following is a reconciliation of the major classes of line items constituting loss from discontinued operations to loss from discontinued operations shown in the Statement of Operations: Three months ended Nine months ended September 30, September 30, 2019 2018 2019 2018 Revenue $ — $ 342,661 $ 115,000 $ 1,144,103 Cost of revenue 1,337 552,127 141,647 1,471,890 Research and development 12,613 527,631 197,663 1,774,193 General and administrative 40,332 9,513 79,306 33,762 Sales and marketing 24,514 264,705 59,431 588,937 Impairment (1) — — 405,000 — Loss from discontinued operations $ (78,796) $ (1,011,315) $ (768,047) $ (2,724,679) (1) Impairment charge was calculated as the net book value of assets held for sale prior to the impairment less the expected net proceeds from the planned sale. The expected net proceeds were based on the estimated fair value of the net assets held for sale less the estimated cost to sell the net assets held for sale. For the three and nine months ended September 30, 2019, the Company recorded a loss on the sale of discontinued operations of $9,107.

Lease
Lease	Note 5 – Lease The Company leases 14,782 square feet of office and laboratory space located in Austin, Texas. On April 20, 2018, the Company entered into an amendment to its existing operating lease which extended the lease term from May 31, 2018 to May 31, 2021. The annual base rent in the first year of the lease extension was $184,775 and increases by $7,391 in each succeeding year of the lease extension. In addition, the Company is required to pay its proportionate share of operating costs for the building under this triple net lease. The lease does not contain renewal or termination options. On January 1, 2019, the Company adopted ASC 842 utilizing a modified retrospective approach with a date of initial application at the beginning of the period of adoption. At adoption, the Company recognized a right of use asset of $422,819 and lease liability of $427,131. As the discount rate implicit in the lease was not readily determinable and the Company did not have any outstanding indebtedness, the Company utilized market data, giving consideration to remaining term of the lease, to estimate its incremental borrowing rate at 8% per annum for purposes of calculating the right of use asset and lease liability. Future undiscounted minimum payments under the lease, as amended, are as follows: For the Year Ended December 31, Master Lease Sublease Income Net 2019 $ 48,041 $ (36,031) $ 2020 196,477 (147,357) 2021 83,149 (62,362) Total future undiscounted minimum lease payments $ 327,667 $ (245,750) $ Less: imputed interest (20,003) Total lease liability $ 307,664 For the three and nine months ended September 30, 2019, operating cash flows for lease payments totaled $48,042 and $141,045 and the operating lease cost, recognized on a straight-line basis, totaled $48,488 and $145,463. At September 30, 2019, the remaining lease term was 20 months. On September 19, 2019, the Company entered into a sublease with CE+T Energy pursuant to which the Company subleases approximately seventy-five (75%) percent of its Austin, Texas facility to CE+T Energy. Under the sublease, CE+T Energy is obligated to make monthly payments equal to 75% of all sums due under the master lease and 100% of any maintenance and repair costs related to the subleased premises. The sublease replaced a temporary agreement between the Company and CE+T Energy, effective July 22, 2019, that contained similar payment obligations by CE+T Energy for utilization of the subleased premises. Consistent with the master lease, the sublease terminates on May 31, 2021. During the three months ended September 19, 2019, CE+T Energy made payments of $38,949 to the Company related to the subleased premises. The payments included CE+T Energy’s prorated share of rent as well as its prorated and proportionate share of operating costs for the building under the master lease. The Company recognized these payments as a reduction in general and administrative expenses.

Commitments and Contingencies	Note 6 – Commitments and Contingencies License Agreement In 2015, the Company entered into licensing agreements which expire on February 7, 2033. Per the agreements, the Company has an exclusive royalty-free license associated with semiconductor power switches which enhances its intellectual property portfolio. The agreements include both fixed payments, all of which were paid prior to 2017, and ongoing variable payments. The variable payments are a function of the number of associated patent filings pending and patents issued under the agreements. The Company will pay $10,000 for each patent filing pending and $20,000 for each patent issued each year of the agreements, up to a maximum of $100,000 each year (i.e. five issued patents). In April 2019, a patent associated with these agreements was issued and the Company recorded, as a non-cash activity, an asset and a corresponding liability of $232,367, representing the estimated present value of future payments under the licensing agreements for this issued patent. Through September 30, 2019, a total of three patents associated with the agreements were issued. The estimated present value of future payments under the licensing agreements is shown on the Balance Sheet as other long-term liabilities while the capitalized licensing agreement assets are shown on the Balance Sheet as intangible assets. The Company is accruing interest for future payments related to the issued patents associated with these agreements. Indemnification Obligations In connection with the sale of its power conversion systems division, the Company entered into an Asset Purchase Agreement with CE+T Energy that contains mutual indemnification obligations for breaches of representations, warranties and covenants and for certain other matters, including indemnification by the Company for assets and liabilities excluded from the sale and by CE+T Energy for liabilities assumed in the sale.

Common and Preferred Stock
Common and Preferred Stock	Note 7 — Common and Preferred Stock On February 21, 2019, a shareholder converted 708,430 shares of preferred stock to 70,843 shares of common stock. On March 7, 2019 and following an initial notice of non-compliance from Nasdaq on September 7, 2018, the Company received a notice letter from Nasdaq indicating that it had not regained compliance with the minimum bid price requirement of $1 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). However, Nasdaq determined that the Company was eligible for an additional 180-day period, or until September 3, 2019, to regain compliance based on the fact that it met the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the minimum bid price requirement, and it had provided written notice to Nasdaq of its intent to cure the deficiency during this second compliance period, by effecting a reverse stock split, if necessary. On August 15, 2019, after receipt of stockholder and Board approval, the Company filed a Certificate of Amendment to the Certificate of Incorporation of Ideal Power Inc. to effect a one-for-ten (1:10) reverse stock split of all issued and outstanding shares of the Company’s common stock. The Company’s common stock began trading on the Nasdaq Capital Market on a split-adjusted basis when the market opened on August 20, 2019. The par value of the Company’s common stock remained unchanged at $0.001 per share after the reverse stock split. The reverse stock split reduced the number of shares of the Company’s common stock outstanding from 14,722,840 to 1,474,001, inclusive of full shares received for fractional interests. The number of shares of the Company’s common stock issuable upon conversion of the outstanding shares of the Company’s preferred stock was reduced from 810,000 shares to 81,000 shares. The number of authorized shares of the Company’s common stock was not changed by the reverse stock split. The reverse stock split proportionately affected the number of shares of the Company’s common stock available for issuance under the Company’s equity incentive plans. The number of shares of the Company’s common stock subject to all options, warrants and stock awards of the Company outstanding immediately prior to the reverse stock split were proportionately adjusted in accordance with their terms. On September 4, 2019, the Company received a notice letter from Nasdaq that the Company had regained compliance with the minimum bid price requirement and the matter was closed. On August 21, 2019, the Company was notified by the Nasdaq Listing Qualifications Department that the Company was not in compliance with the minimum stockholders’ equity requirement under Nasdaq Listing Rule 5550(b)(1) for continued listing on the Nasdaq Capital Market because the Company’s stockholders’ equity was below the required minimum of $2.5 million, and, as of the date of the notification, the Company did not meet the alternatives of market value of listed securities or net income from continuing operations. In accordance with Nasdaq Listing Rules, the Company had 45 calendar days, or until October 3, 2019, to submit a plan to regain compliance. The Company submitted a plan of compliance on October 3, 2019 addressing how it intends to regain compliance with Nasdaq Listing Rule 5550(b). On October 31, 2019, Nasdaq notified the Company of approval of the compliance plan, and Nasdaq granted the Company an extension through November 30, 2019 to take action to evidence compliance with Nasdaq Listing Rule 5550(b), which will require, among other things, that the Company demonstrate compliance within its periodic report for the fiscal year ending December 31, 2019. If the Company does not regain compliance, the Company may be subject to delisting.

Legal Proceedings	Note 10 — Legal Proceedings On April 11, 2019, the Company entered into an asset purchase agreement (the “APA”) with Pathion Holdings, Inc., a Delaware corporation, and Pathion, Inc., a Delaware corporation (together “Pathion”) to sell certain assets (the “PPSA Assets”) related to the Company’s PPSA™ / Power Conversion Systems business (“PPSA Business”). The purchase price consisted of $500,000 in cash and 150,000 shares of the common stock of Pathion Holdings, Inc. Pursuant to the APA, Pathion would also assume certain liabilities relating to the PPSA Business. On June 13, 2019, the Company filed a petition in the district court of the 250 th Judicial District in Travis County (the "Court"), naming Pathion and certain Pathion officers as defendants. The petition asserts breach of the APA and the related Sublease Agreement for failure by Pathion to pay any cash amounts due thereunder, and fraudulent inducement as Pathion and the individual defendants misrepresented Pathion’s financial position and its stock value. The petition also requested a declaratory judgment that Pathion has no rights to the PPSA Assets. On July 15, 2019, Pathion filed a general denial to the Company's petition. On July 22, 2019, the Company filed a motion for partial summary judgment on its declaratory judgment action and for severance. Pathion responded to the motion for summary judgment on August 6, 2019. That same day, Pathion filed a counterclaim, and requested injunctive relief and a declaratory judgment. On August 13, 2019, the Court conducted a hearing on the Company’s motion for summary judgment. On August 23, 2019, the Court issued an order granting the Company’s motion for summary judgment and fees and severing judgment from remaining claims. Under this order, the Court declared and decreed that Pathion has no rights to the PPSA Assets and awarded the Company $24,800 in legal fees. On October 15, 2019, the Court issued a writ of garnishment against Pathion’s bank to enable collection of these legal fees. On October 14, 2019, the Court granted Pathion's counsel's motion to withdraw. Ten days later, a new lawyer appeared for the Pathion Defendants, and the next day, October 25, 2019, the Court issued a scheduling order requiring Pathion to produce documents and appear for deposition in December 2019. The Court set trial to begin on August 31, 2020. At this time, the Company is unable to estimate the possible gain or loss, if any, related to this proceeding.

The Company also issued to the investors warrants to purchase up to an aggregate of 1,766,751 shares of common stock at an exercise price of $2.32 per share that are immediately exercisable and will expire five years from the issuance date. As compensation to the placement agent in the Offering, in addition to a cash fee for its services, the Company also issued to the placement agent a warrant to purchase up to 70,670 shares of common stock, with an exercise price of $2.9716 per share. The other terms of the placement agent warrant are substantially the same as the investor warrants. For his investment of $500,000, Dr. Bell received 201,914 shares of common stock and 252,393 warrants in the Offering. Pursuant to a registration rights agreement, the Company has agreed to file a registration statement with the SEC to register the resale of the shares of common stock and the shares of common stock issuable upon exercise of the warrants issued in the Offering within 30 days of the closing of the Offering.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying unaudited financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for Form 10-Q. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“U.S.GAAP”) have been condensed or omitted pursuant to such rules and regulations. The Balance Sheet at December 31, 2018 has been derived from the Company’s audited financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on April 1, 2019. In the opinion of management, these financial statements reflect all normal recurring, and other adjustments, necessary for a fair presentation. These financial statements should be read in conjunction with the audited financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. Operating results for interim periods are not necessarily indicative of operating results for an entire fiscal year or any other future periods.
Reverse Stock Split	Reverse Stock Split On August 15, 2019, the Company effected a reverse stock split of the outstanding shares of its common stock by a ratio of one-for-ten, and its common stock began trading on the Nasdaq Capital Market on a split-adjusted basis on August 20, 2019. The par value of the Company’s common stock remained unchanged at $0.001 per share after the reverse stock split. All share amounts, per share data, share prices, exercise prices and conversion rates set forth in these notes and the accompanying unaudited condensed financial statements have, where applicable, been adjusted retroactively to reflect the reverse stock split. See Note 7.
Liquidity and Going Concern	Liquidity and Going Concern The Company had a net loss of $3.1 million and used $2.4 million of cash in operating activities for the nine months ended September 30, 2019. At September 30, 2019, the Company had net working capital of $0.4 million and the Company’s principal source of liquidity consisted of $0.8 million of cash and cash equivalents. The Company’s cash and cash equivalent balance at September 30, 2019 relative to its estimate of future operating cash requirements led to substantial doubt about the ability of the Company to continue as a going concern. The Company’s independent registered public accounting firm, in its report on the Company’s 2018 financial statements, raised substantial doubt about the Company’s ability to continue as a going concern. On November 13, 2019, the Company completed a private placement of the Company’s common stock and warrants to purchase common stock for aggregate gross proceeds of $3.5 million and estimated net proceeds of $3.1 million, thereby alleviating the substantial doubt about the Company’s ability to continue as a going concern for at least the next twelve months from the date of issuance of these financial statements. See Note 11. The accompanying condensed financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The ability of the Company to continue as a going concern is dependent on its ability to raise additional capital and to develop profitable operations through implementation of its current business initiatives, however, there can be no assurances that the Company will be able to raise additional capital on favorable terms, or at all, or develop profitable operations. The accompanying condensed financial statements do not include any adjustments that might be necessary if the Company is unable to continue as a going concern.
Recently Adopted Standards and Recent Accounting Pronouncements	Recently Adopted Standards In February 2016, the Financial Accounting Standards Board issued Accounting Standards Update2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities on the balance sheet. Most prominent among the amendments is the recognition of assets and liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. Under the new standard, disclosures are required to meet the objective of enabling users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. The Company adopted this standard effective January 1, 2019. Upon adoption, the Company recognized its lease commitment as a lease liability and right-of-use asset. For more details regarding the lease commitment, see Note 5. Recent Accounting Pronouncements Management does not believe that any other recently issued, but not yet effective, accounting standard, if adopted, would have a material impact on the Company’s financial statements.

Description of Other Regulatory Limitations			On March 7, 2019 and following an initial notice of non-compliance from Nasdaq on September 7, 2018, the Company received a notice letter from Nasdaq indicating that it had not regained compliance with the minimum bid price requirement of $1 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). However, Nasdaq determined that the Company was eligible for an additional 180-day period, or until September 3, 2019, to regain compliance based on the fact that it met the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, with the exception of the minimum bid price requirement, and it had provided written notice to Nasdaq of its intent to cure the deficiency during this second compliance period, by effecting a reverse stock split, if necessary.
