NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) (Unaudited) Note 1 - Organization and Description of Business SenesTech, Inc. (referred to in this report as “SenesTech,” the “Company,” “we,” “us”, or “our”) was formed in July 2004 and incorporated in the state of Nevada. We subsequently reincorporated in the state of Delaware in November 2015. Our corporate headquarters is in Phoenix, Arizona. We have developed and are commercializing a global, proprietary technology for managing animal pest populations, initially rat populations, through fertility control. Although there are myriad tools available to control rat populations, most rely on some form of lethal method to achieve effectiveness. Each of these solutions is inherently limited by rat species’ resilience and survival mechanisms as well as their extraordinary rate of reproduction. ContraPest ® , our initial product, is unique in the pest control industry in attacking the reproductive systems of both male and female rats, which our field data shows will result in a sustained reduction of the rat population. Rats have plagued humanity throughout history. They pose significant threats to the health and food security of many communities. In addition, rodents cause significant product loss and damage through consumption and contamination. Rats also cause significant damage to critical infrastructure by burrowing beneath foundations and gnawing on electrical wiring, insulation, fire proofing systems, electronics and equipment. The most prevalent solution to rat infestations is the use of increasingly powerful rodenticides. Although these solutions provide short term results, there are growing concerns about secondary exposure and bioaccumulation of rodenticides in the environment, as well as concerns about rodenticides that have no antidotes. The pest management industry and Pest Management Professionals (“PMPs”) are being asked for new solutions that are both effective and less toxic. Our goal is to provide customers with not only a highly effective solution to combat their rat problems, but also offer a non-lethal option to serve customers that are looking to decrease or remove the amount of rodenticide used in their pest control programs. ContraPest is a liquid bait containing the active ingredients 4-vinylcyclohexene diepoxide (“VCD”) and triptolide. ContraPest limits reproduction of male and female rats beginning with the first breeding cycle following consumption. ContraPest is being marketed for use in controlling Norway and roof rat populations. We began the registration process with the United States Environmental Protection Agency (the “EPA”) for ContraPest on August 23, 2015. On August 2, 2016, the EPA granted an unconditional registration for ContraPest as a Restricted Use Product (“RUP”), due to the need for applicator expertise for deployment. On October 18, 2018, the EPA approved the removal of the RUP designation. We believe ContraPest is the first and only non-lethal, fertility control product approved by the EPA for the management of rodent populations. In June 2022, we received EPA registration and approval our new Elevate Bait System with ContraPest. This innovative bait system provides a unique and effective delivery system designed to target roof rats in elevated spaces. In addition to the EPA registration of ContraPest in the United States, we must obtain registration from the various state regulatory agencies prior to selling in each state. To date, we have received registration for ContraPest in all 50 states and the District of Columbia, 48 of which have approved the removal of the RUP designation. In addition to product registration, the EPA also approves all labeling (the container label, instructional inserts, and the Safety Data Sheet (“SDS”)) of ContraPest. Generally, states accept the EPA approved label as is. ContraPest’s labeling was submitted to the states at the initial registration and is resubmitted during state scheduled reregistration or for any significant labeling change requiring EPA approval. 5 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 1 - Organization and Description of Business – (continued) We expect to continue to pursue regulatory approvals and amendments to the existing U.S. registration for ContraPest to broaden the marketability and use of ContraPest, and if ContraPest begins to generate sufficient revenue, regulatory approvals for additional jurisdictions beyond the United States. In certain cases, our EPA and state registrations require completion of additional testing and certifications even though we have received approval for the product or its labelling. We continue to seek to comply with these requirements. We also continue to research and develop enhancements to ContraPest that align with our target verticals and other potential fertility control options for additional species and alternate delivery systems. Going Concern Our financial statements as of June 30, 2022, December 31, 2021 and June 30, 2021 were prepared under the assumption that we would continue as a going concern, the report of our independent registered public accounting firm that accompanies our financial statements for the years ended December 31, 2021 and December 31, 2020 contains a going concern qualification in which such firm expressed substantial doubt about our ability to continue as a going concern, based on the financial statements at that time. Specifically, as noted above, we have incurred operating losses since our inception, and we expect to continue to incur significant expenses and operating losses for the foreseeable future. These prior losses and expected future losses have had, and will continue to have, an adverse effect on our financial condition. If we encounter continued issues or delays in the commercialization of ContraPest, our prior losses and expected future losses could have an adverse effect on our financial condition and negatively impact our ability to fund continued operations, obtain additional financing in the future and continue as a going concern. There are no assurances that such financing, if necessary, will be available to us at all or will be available in sufficient amounts or on reasonable terms. Our financial statements do not include any adjustments that may result from the outcome of this uncertainty. If we are unable to generate additional funds in the future through additional financings, sales of our products, licensing fees, royalty payments or from other sources or transactions, we will exhaust our resources and will be unable to continue operations. Liquidity and Capital Resources Since our inception, we have sustained significant operating losses in the course of our research and development and commercialization activities and expect such losses to continue for the near future. We have generated limited revenue to date from product sales, research grants and licensing fees received under our former license agreement. We have primarily funded our operations to date through the sale of equity securities, including convertible preferred stock, common stock and warrants to purchase common stock. See Note 10 for a description of our public equity sales. We have also raised capital through debt financing, consisting primarily of convertible notes and government loan programs, and, to a lesser extent, payments received in connection with product sales, research grants and licensing fees. Through June 30, 2022, we received net proceeds of $ 89.6 million from our sales of common stock, preferred stock and warrant exercises and issuance of convertible and other promissory notes, an aggregate of $ 1.7 million from licensing fees and an aggregate of $ 2.0 million in net product sales. As of June 30, 2022, we had an accumulated deficit of $ 117.4 million and cash and cash equivalents of $ 5.0 million. Our ultimate success depends upon the outcome of a combination of factors, including the following: (i) successful commercialization of ContraPest and maintaining and obtaining regulatory approval of our products and product candidates; (ii) market acceptance, commercial viability and profitability of ContraPest and other products; (iii) the ability to market our products and establish an effective sales force and marketing infrastructure to generate significant revenue; (iv) the success of our research and development; (v) the ability to retain and attract key personnel to develop, operate and grow our business; and (vi) our ability to meet our working capital needs. 6 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 1 - Organization and Description of Business – (continued) Based upon our current operating plan, we expect that cash and cash equivalents at June 30, 2022, in combination with anticipated revenue and any additional sales of our equity securities, will be sufficient to fund our current operations for at least the next six to nine months. We have evaluated and will continue to evaluate our operating expenses and will concentrate our resources toward the successful commercialization of ContraPest in the United States. However, if anticipated revenue targets and margin targets are not achieved or expenses are more than we have budgeted, we may need to raise additional financing before that time. If we need more financing, including within the next six to nine months, and we are unable to raise necessary capital through the sale of our securities, we may be required to take other measures that could impair our ability to be successful and operate as a going concern. In any event, we may require additional capital in order to fund our operating losses and research and development activities before we become profitable and may opportunistically raise capital. We may never achieve profitability or generate positive cash flows, and unless and until we do, we will continue to need to raise capital through equity or debt financing. If such equity or debt financing is not available at adequate levels or on acceptable terms, we may need to delay, limit or terminate commercialization and development efforts or discontinue operations. Basis of Presentation Our accompanying unaudited condensed financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with the U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations. In our opinion, the unaudited condensed financial statements include all material adjustments, all of which are of a normal and recurring nature, necessary to present fairly our financial position as of June 30, 2022, our operating results for the three months and six months ended June 30, 2022 and 2021, and our cash flows for the six months ended June 30, 2022 and 2021. The accompanying financial information as of December 31, 2021 is derived from audited financial statements. Interim results are not necessarily indicative of results for a full year. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 29, 2022. All amounts shown in these financial statements and accompanying notes are in thousands, except percentages and per share and share amounts. Note 2 - Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts and classification of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. The significant estimates in our financial statements include the valuation of preferred stock, if issued, common stock and related warrants, and other stock-based awards. Actual results could differ from such estimates. Reclassifications Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications had no material impact on net earnings, financial position or cash flows. Cash and Cash Equivalents We consider money market fund investments to be cash equivalents. We had cash equivalents in the form of money market fund investment of $ 4,095 and $ 8,793 at June 30, 2022 and December 31, 2021, respectively, included in cash as reported. 7 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 2 - Summary of Significant Accounting Policies – (continued) Accounts Receivable-Trade Accounts receivable-trade consist primarily of receivables from customers. We provide an allowance for doubtful trade receivables equal to the estimated uncollectible amounts. That estimate is based on historical collection experience, current economic and market conditions and a review of the current status of each customer’s trade accounts receivable. We had allowance for doubtful trade receivables at June 30, 2022 of $ 12 . We did not have any allowance for doubtful trade receivables at December 31, 2021. Inventories Inventories are stated at the lower of cost or market value, using the first-in, first-out convention. Inventories consist of raw materials, work in progress and finished goods. Raw materials are stocked to reduce the risk of impact on manufacturing for potential supply interruptions due to the COVID-19 pandemic, supply chain issues or long lead times on certain ingredients. Components of inventory were: June 30, December 31, 2022 2021 Raw materials $ 880 $ 937 Work in progress 5 5 Finished goods 113 88 Total inventory 998 1,030 Less: Reserve for obsolete ( 22 ) ( 29 ) Total net inventory $ 976 $ 1,001 Prepaid Expenses Prepaid expenses consist primarily of payments made for director and officer insurance, director compensation, rent, legal and inventory purchase deposits and seminar/trade show fees to be expensed in the current year. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Equipment held under finance leases are stated at the present value of minimum lease payments less accumulated amortization. Depreciation on property and equipment is computed using the straight-line method over the estimated useful lives of the respective assets. The cost of leasehold improvements is amortized over the life of the improvement or the term of the lease, whichever is shorter. Equipment held under finance leases is amortized over the shorter of the lease term or estimated useful life of the asset. We incur repair and maintenance costs on our major equipment, which are expensed as incurred. 8 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 2 - Summary of Significant Accounting Policies – (continued) Impairment of Long-Lived Assets Long-lived assets, such as property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require long- lived assets or asset groups to be tested for possible impairment, we compare the undiscounted cash flows expected to be generated from the use of the asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment charge is recognized to the extent that the carrying amount exceeds its fair value. Fair value is determined through various valuation techniques, such as discounted cash flow models and the use of third-party independent appraisals. We have not recorded an impairment of long-lived assets since inception. Revenue Recognition Effective January 1, 2018, we adopted Accounting Standards Codification (“ASC”) 606 — Revenue from Contracts with Customers (“ASC 606”) . Under ASC 606, we recognize revenue from the commercial sales of products, licensing agreements and contracts to perform pilot studies by applying the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to each performance obligation in the contract; and (5) recognize revenue when each performance obligation is satisfied. We recognize revenue when product is shipped at a fixed selling price on payment terms of 30 to 120 days from invoicing. We recognize other revenue earned from pilot studies, consulting and implementation services upon the performance of specific services under the respective service contract. We derive revenue primarily from commercial sales of products, net of discounts and promotions, as well as consulting and implementation services provided in conjunction with our product deployments. Deferred revenue represents payments that have been received in advance of fulfillment of these orders. These product orders are anticipated to be fulfilled in future periods. Research and Development Research and development costs are expensed as incurred. Research and development expenses primarily consist of salaries and benefits for research and development employees, stock-based compensation, consulting fees, lab supplies, costs incurred related to conducting scientific trials and field studies, regulatory compliance costs, as well as manufacturing costs associated with process improvement and other research. Research and development expenses include an allocation of facilities related costs, including depreciation of equipment. Stock-Based Compensation Stock-based awards, consisting of stock options and restricted stock units expected to be settled in shares of our common stock, are recorded as equity awards. The grant date fair value of these awards is measured using the Black-Scholes option pricing model for stock options and grant date market value for restricted stock units. We expense the grant date fair value of stock options on a straight-line basis over their respective vesting periods. The stock-based compensation expense recorded for the three and six months ended June 30, 2022 and 2021, was as follows: Three Months Ended June 30, Six Months Ended June 30, 2022 2021 2022 2021 Research and development $ 3 $ - $ 4 $ 2 Selling, general and administrative 203 182 426 335 Total stock-based compensation expense $ 206 $ 182 $ 430 $ 337 See Note 11 for additional discussion on stock-based compensation. 9 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 2 - Summary of Significant Accounting Policies – (continued) Income Taxes We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax bases of assets and liabilities and net operating loss carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. These deferred tax assets are subject to periodic assessments as to recoverability and if it is determined that it is more likely than not that the benefits will not be realized, valuation allowances are recorded which would increase the provision for income taxes. In making such determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations. We apply a more-likely-than-not recognition threshold for all tax uncertainties. Only those benefits that have a greater than fifty percent likelihood of being sustained upon examination by the taxing authorities are recognized. Based on our evaluation, we have concluded there are no significant uncertain tax positions requiring recognition in our financial statements. We recognize interest and/or penalties related to uncertain tax positions in income tax expense. There are no uncertain tax positions as of June 30, 2022 or December 31, 2021 and, as such, no interest or penalties were recorded in income tax expense. Comprehensive Loss Net loss and comprehensive loss were the same for all periods presented; therefore, a separate statement of comprehensive loss is not included in the accompanying financial statements. Loss Per Share Attributable to Common Stockholders Basic loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted loss per share attributable to common stockholders is computed by dividing the loss attributable to common stockholders by the weighted average number of common shares and potentially dilutive securities outstanding for the period determined using the treasury stock and if-converted methods. For purposes of the computation of diluted loss per share attributable to common stockholders, common stock purchase warrants, and common stock options are considered to be potentially dilutive securities but have been excluded from the calculation of diluted loss per share attributable to common stockholders because their effect would be anti-dilutive given the net loss reported for the three and six months ended June 30, 2022 and 2021. Therefore, basic and diluted loss per share attributable to common stockholders are the same for each period presented. 10 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 2 - Summary of Significant Accounting Policies – (continued) The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted loss per share attributable to common stockholders (in common stock equivalent shares): June 30, 2022 2021 Common stock purchase warrants 4,531,447 4,553,234 Restricted stock units - 667 Common stock options 1,473,320 1,069,661 Total 6,004,767 5,623,562 Accounting Standards Issued but Not Yet Adopted There have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our condensed consolidated financial statements. Note 3 - Fair Value Measurements The carrying amounts of our financial instruments, including accounts payable and accrued liabilities, approximate fair value due to their short maturities. The estimated fair value of our notes, not recorded at fair value, are recorded at cost or amortized cost which was deemed to estimate fair value. Note 4 - Credit Risk We are potentially subject to concentrations of credit risk in our accounts receivable. Credit risk with respect to receivables is limited due to the number of companies comprising our customer base. At June 30, 2022, we had $ 12 in potentially uncollectable accounts and recorded a reserve for uncollectable accounts in that amount. We did not have any potentially uncollectable accounts at December 31, 2021 and therefore, did not record a reserve for uncollectable accounts at December 31, 2021. We do not require collateral or other securities to support its accounts receivable.

The new warrant did not contain the antidilution price adjustment protection that was contained within the exercised warrants. In June 2018, we recorded stock compensation expense of $ 1,700 representing the fair value of the of 56,696 inducement warrants issued.

NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 9 - Common Stock Warrants and Common Stock Warrant Liability – (continued) For so long as the 2020 Warrants remain outstanding, the exercise price and number of shares of common stock issuable upon exercise of the warrants are subject to adjustment as follows: (a) upon payment of a stock dividend or other distribution on a class or series of shares of common stock, not including shares issued under this warrant; (b) upon subdivision (by stock spilt, stock dividend, recapitalization, or otherwise) or combination (by reverse stock split or otherwise) of shares of common stock; or (c) upon the issuance of any shares of capital stock by reclassification of shares of the common stock. In the event that we declare or make any dividend or other distribution of our assets to holders of our common stock, each 2020 Warrant holder will be entitled to participate in such distribution to the same extent that such holder would have participated therein if the holder had held the number of shares of common stock acquirable upon exercise of the 2020 Warrant. In the event of a Fundamental Transaction, as described in the 2020 Warrants and generally including the sale, transfer or other disposition of all or substantially all of our properties or assets; our consolidation or merger with or into another person or reorganization; a recapitalization, reorganization or reclassification in which our common stock is converted into other securities, cash or property; or any acquisition of our outstanding common stock that results in any person or group becoming the beneficial owner of 50 % of the voting power represented by our outstanding common stock, then the holders of the 2020 Warrants will be entitled to receive upon exercise of such warrants the kind and amount of securities, cash, assets or other property that the holders would have received had they exercised the 2020 Warrants immediately prior to such Fundamental Transaction. Subject to certain limitations, in the event of a Fundamental Transaction the 2020 Warrant holder may at its option require us or any Successor Entity to purchase such warrant from the holder by paying to the holder an amount of cash equal to the Black Scholes Value of the remaining unexercised portion of the 2020 Warrant on the date of the consummation of the Fundamental Transaction. Any time that we grant, issue or sell any securities pro rata to all of the record holders of our common stock (the “2020 Purchase Right”), each holder of 2020 Warrants will be entitled to acquire the aggregate amount of securities that the holder could have acquired if the holder had held the number of shares of common stock acquirable upon exercise of the applicable 2020 Warrant. However, to the extent that an exercise of a 2020 Purchase Right would exceed the Beneficial Ownership Limitation (defined below), then to such extent the 2020 Purchase Right will be held in abeyance until such time, if ever, that complete exercise of the 2020 Purchase Right would not exceed the Beneficial Ownership Limitation. After the Initial Exercisability Date, the 2020 Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise. If, at the time a holder exercises the 2020 Warrant (but not sooner than six months following the date of such warrant), a registration statement registering the issuance of the shares of common stock underlying the 2020 Warrants under the Securities Act is not then effective or available, nor is any current prospectus thereto available, and an exemption from registration under the Securities Act is not available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the number of shares of common stock determined according to a formula set forth in the 2020 Warrant. Limitations on Exercise . A holder (together with its affiliates) may not exercise any portion of the 2020 Warrants to the extent that the holder would own more than 4.99% of the outstanding common stock after exercise (the “Beneficial Ownership Limitation”), except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the Beneficial Ownership Limitation up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the 2020 Warrants. No fractional shares of common stock will be issued in connection with the exercise of a 2020 Warrant. In lieu of fractional shares, we will either pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share. 16 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 9 - Common Stock Warrants and Common Stock Warrant Liability – (continued) Except as otherwise provided in the 2020 Warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the 2020 Warrants do not have the rights or privileges of holders of our common stock, including any voting rights, unless and until they exercise such warrants.

Pursuant to the agreement, the per share exercise price of the original warrants were reduced from $ 2.88 and $ 3.05 , respectively, to $ 1.725 . Per recent proposed guidance of ASC 260, we determined that this was an exchange of the existing 1,700,680 warrants that were affected and the difference between the fair value of the warrants immediately prior to modification of terms and immediately after the adjustment was a cost of raising capital and was recorded as a reduction of equity. The difference between the fair value of the warrants immediately prior to modification of terms and immediately after the adjustment was calculated as $ 237 , using a Black Scholes model based on the following significant inputs: On October 26, 2020: common stock price of $ 1.47 ; comparable company volatility of 96.5 %; remaining term 4.5 -4.8 years; dividend yield of 0 % and risk-free interest rate of 0.18 . 19 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 10 - Stockholders’ Deficit Capital Stock We organized under the laws of the state of Nevada on July 27, 2004 and subsequently reincorporated under the laws of the state of Delaware on November 10, 2015. In connection with the reincorporation, as approved by the stockholders, we changed our authorized capital stock to consist of (i) 100 million shares of common stock, $ .001 par value, and (ii) 2 million shares of preferred stock, $ 0.001 par value, designated as Series A convertible preferred stock. In December 2015, we amended our Certificate of Incorporation to change our authorized capital stock to provide for 15 million authorized shares of preferred stock of which 7,515,000 was designated as Series B convertible preferred stock, par value $ .001 per share. Prior to November 10, 2015, our authorized capital stock consisted of 100 million shares of common stock, $ .001 par value, and 10 million shares of preferred stock, $ .001 par value. Common Stock We had 12,212,950 and 12,207,283 shares of common stock issued and outstanding as of June 30, 2022 and December 31, 2021, respectively. During the six months ended June 30, 2022, we issued 5,667 shares of common stock as follows: ● an aggregate of 5,000 shares in connection with a restricted stock grant that was issued and vested on February 25, 2022 for services. ● an aggregate of 667 shares in connection with a restricted stock grant that vested on May 4, 2022 for services. Note 11 - Stock-Based Compensation On June 12, 2018, our stockholders approved the 2018 Equity Incentive Plan (the “2018 Plan”) to replace our 2015 Equity Incentive Plan (the “2015 Plan”). On July 8, 2020, our stockholders approved an amendment to the 2018 Plan to increase the number of shares of common stock available for issuance under the 2018 Plan by 800,000 shares from 50,000 to 850,000 . In addition, up to 122,279 shares of our common stock previously reserved for issuance under the 2015 Plan are available for issuance under the 2018 Plan to the extent such shares were available for issuance under the 2015 Plan as of June 12, 2018 or thereafter cease to be subject to awards outstanding under the 2015 Plan, such as by expiration, cancellation, or forfeiture of such awards. On June 24, 2021, our stockholders approved an amendment to the 2018 Plan to increase the number of shares of common stock available for issuance under the 2018 Plan by 3,000,000 shares. Stock options are generally issued with a per share exercise price equal to no less than fair market value of our common stock at the date of grant. Options granted under the 2018 Plan generally vest immediately, or ratably over a two- to 36-month period coinciding with their respective service periods. Options under the 2018 Plan generally have a term of five years . Certain stock option awards provide for accelerated vesting upon a change in control. As of June 30, 2022, we had 2,457,600 shares of common stock available for issuance under the 2018 Plan. Stock Options We measure the fair value of stock options with service-based vesting criteria to employees, directors and consultants on the date of grant using the Black-Scholes option pricing model. The Black-Scholes valuation model requires us to make certain estimates and assumptions, including assumptions related to the expected price volatility of our stock, the period during which the options will be outstanding, the rate of return on risk-free investments, and the expected dividend yield for our stock. 20 SENESTECH, INC. NOTES TO CONDENSED FINANCIAL STATEMENTS (In thousands, except share and per share data) Note 11 - Stock-Based Compensation – (continued) We did not issue any stock options in the three months ended June 30, 2022. The weighted-average assumptions used in the Black-Scholes option-pricing model used to calculate the fair value of options granted during the six months ended June 30, 2022 were as follows: Expected volatility 77.0 % Expected dividend yield — Expected term (in years) 3.5 Risk-free interest rate 1.7 % The weighted average grant date fair value of options granted during the six months ended June 30, 2022 was $ 0.444 per share, as per the table above. Due to our limited operating history and lack of company-specific historical or implied volatility, the expected volatility assumption was determined based on historical volatilities from traded options of biotech companies of comparable size and stability, whose share prices are publicly available. The expected term of options granted to employees is calculated based on the mid-point between the vesting date and the end of the contractual term according to the simplified method as described in SEC Staff Accounting Bulletin 110 because we do not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its awards have been outstanding. For non-employee options, the expected term of options granted is the contractual term of the options. The risk-free interest rate is determined by reference to the implied yields of U.S. Treasury securities with a remaining term equal to the expected term assumed at the time of grant. The expected dividend assumption is based on our history and expectation of dividend payouts. We have not paid and do not intend to pay dividends. The following table summarizes the stock option activity, for both equity plans, for the periods indicated as follows: Number of Options Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Term (years) Aggregate Intrinsic Value (1) Outstanding at December 31, 2021 1,087,820 $ 4.08 3.9 $ — Granted 390,000 $ 0.82 4.9 $ — Exercised — $ — — $ — Forfeited ( 4,500 ) $ — — $ — Expired — $ — — $ — Outstanding at June 30, 2022 1,473,320 $ 3.24 3.0 $ — Exercisable at June 30, 2022 955,871 $ 3.68 1.7 $ — (1) The aggregate intrinsic value in the table was calculated based on the difference between the estimated fair market value of our stock and the exercise price of the underlying options. The estimated stock values used in the calculation were $ 0.98 and $ 0.53 per share for the year ended December 31, 2021 and the six months ended June 30, 2022, respectively. 21 SENESTECH, INC.

At June 30, 2022, the total compensation cost related to restricted stock units and unvested options not yet recognized was $ 327 , which will be recognized over a weighted average period of 31 months , assuming the employees and non-employee s complete their service period required for vesting. Note 12 - Commitments and Contingencies Legal Proceedings In July 2020, Kennan E. Kaeder, our former corporate general counsel (the “Plaintiff”), commenced an action against us in the Superior Court of the State of California, for the County of San Diego. The complaint alleges, among other things, that we breached the Plaintiff’s employment contract with us, as well as the implied covenant of good faith and fair dealing, by refusing to issue him the balance of stock options he claims we owe him. In September 2021, the Plaintiff served us and also named the following individuals as defendants: Loretta Mayer, Cheryl Dyer, Thomas C. Chesterman, Kim Wolin, Grover Wickersham, Marc Dumont, Bob Ramsey, Matthew Szot, Julia Williams, and Bill Baker. We do not believe that all of the defendants have yet been served. The Plaintiff alleges that such individuals agreed to knowingly and wrongfully withhold the stock options owed to him and are knowingly in receipt of stolen property. The Plaintiff seeks compensatory damages in excess of $ 500,000 , treble damages, and reasonable attorneys’ fees. We do not believe the claims described above have merit and intend to aggressively defend against these accusations. We do not believe that this litigation is likely to have a material effect on our operations. 22 SENESTECH, INC.
