BASIS OF PRESENTATION

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Nature of Business SenesTech, Inc. (subsequently referred to in this report as “we,” “us,” “our,” or “our company”) was incorporated in the state of Nevada in July 2004. On November 12, 2015, we subsequently reincorporated in the state of Delaware. Our corporate headquarters and manufacturing site are in Phoenix, Arizona. We have developed and are commercializing a global, proprietary technology for managing animal pest populations, initially rat and mouse populations, through fertility control. Our current products are known as ContraPest ® , Evolve TM and Evolve Mouse. Our initial product ContraPest is a liquid bait containing the active ingredients 4-vinylcyclohexene diepoxide 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. In addition to the U.S. Environmental Protection Agency (“EPA”) registration of ContraPest, 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 (49 such states and the District of Columbia have approved the removal of the Restricted Use designation), as well as two major U.S. territories, Puerto Rico and The U.S. Virgin Islands. In January 2024, we launched Evolve, which is a soft bait containing the active ingredient cottonseed oil. Evolve limits reproduction of male and female rats beginning with the first breeding cycle following consumption. Evolve is considered a minimum risk pesticide under the EPA Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”), Section 25(b). We must obtain registration from the various state regulatory agencies that do not accept the federal exemption. To date, we are authorized to sell Evolve in 45 states, and two major U.S. territories, Puerto Rico and The U.S. Virgin Islands. In May 2024, we launched our latest product Evolve Mouse, a modified version of our soft bait technology containing the active ingredient cottonseed oil. Evolve Mouse limits reproduction of male and female mice after one to two breeding cycles following consumption. Evolve Mouse is also considered a minimum risk pesticide under the EPA’s FIFRA, Section 25(b). We must obtain registration from the various state regulatory agencies that do not accept the federal exemption. To date, we are authorized to sell Evolve Mouse in 34 states, with an additional state authorized effective January 1, 2025. Going Concern Our condensed financial statements as of September 30, 2024 were prepared under the assumption that we would continue as a going concern. The reports of our independent registered public accounting firm that accompanies our financial statements for each of the years ended December 31, 2023 and December 31, 2022 contain 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, 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 fertility control products, our 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 a 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. 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. As of September 30, 2024, we had an accumulated deficit of $134.8 million and cash and cash equivalents of $2.5 million. Our ultimate success depends upon the outcome of a combination of factors, including the following: (i) successful commercialization of fertility control products and maintaining and obtaining regulatory approval of our products and product candidates; (ii) market acceptance, commercial viability and profitability of fertility control products 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. Based upon our current operating plan, we expect that cash and cash equivalents at September 30, 2024, 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 four months. While we have evaluated and continue to evaluate our operating expenses and concentrate our resources toward the successful commercialization of fertility control products in the United States, additional financing will be needed before achieving anticipated revenue targets and margin targets. If 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, additional capital is needed in order to fund our operating losses and research and development activities before we become profitable. 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. Reverse Stock Split On July 23, 2024, we amended our amended and restated certificate of incorporation to effect a 1-for-10 reverse split of our issued and outstanding shares of common stock. The accompanying financial statements and notes thereto give retrospective effect to the reverse stock split for all periods presented. All issued and outstanding common stock, options and warrants exercisable for common stock and per share amounts contained in our financial statements have been retrospectively adjusted. Condensed Financial Statements 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 September 30, 2024, and our operating results and cash flows for the nine month periods ended September 30, 2024 and 2023. The accompanying financial information as of December 31, 2023 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, 2023, filed with the SEC on February 21, 2024. Recent Accounting Pronouncements 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 financial statements. 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 inventory, common stock warrants, and stock-based awards, such as stock options and restricted stock units. Actual results could differ from such estimates. Advertising Costs Advertising costs are expensed as incurred and were $58,000 and $57,000 for the three months ended September 30, 2024 and 2023, respectively, and $180,000 and $147,000 for the nine months ended September 30, 2024 and 2023, respectively. Comprehensive Loss We have no other comprehensive income items for the periods presented. As a result, our net loss and comprehensive loss were the same for the periods presented, and a separate statement of comprehensive loss is not included in the accompanying condensed financial statements.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	9 Months Ended

Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION In 2018, our stockholders approved the adoption of the SenesTech, Inc. 2018 Equity Incentive Plan (the “2018 Plan”), which provides for the issuance of stock-based instruments, such as stock options or restricted stock units, to employees or consultants as deemed appropriate. The 2018 Plan has since been amended and restated on certain occasions, most recently on July 11, 2024, when our stockholders approved an increase to the total number of authorized shares to 207,071 shares. Currently, only stock options are outstanding under the 2018 Plan, which are generally issued with a per share exercise price equal to the fair market value of our common stock at the date of grant. Options granted generally vest ratably over a 12- to 36-month period coinciding with their respective service periods, with terms generally of ten years. Certain stock option awards provide for accelerated vesting upon a change in control. We have 60,008 shares of common stock available for issuance under the 2018 Plan, which reflects the increase to the total number of authorized shares of 200,000 shares approved by our stockholders on July 11, 2024. The following table presents the outstanding stock option activity: Number of Options Weighted Weighted Three months ended September 30, 2024: Outstanding as of June 30, 2024 4,533 $ 899.48 3.8 Granted 143,312 2.81 9.9 Expired (9) 45,013.33 — Outstanding as of September 30, 2024 147,836 (1) 27.56 9.7 Nine months ended September 30, 2024: Outstanding as of December 31, 2023 3,643 1,197.00 4.0 Granted 144,204 2.83 9.9 Forfeited (2) 1,965.36 3.0 Expired (9) 45,013.33 — Outstanding as of September 30, 2024 147,836 (1) 27.56 9.7 Exercisable as of September 30, 2024 6,274 557.32 5.8 (1) Includes options related to 823 shares that are inducement awards and not granted under the 2018 Plan. The weighted average grant date fair value of options granted during the nine months ended September 30, 2024 was $2.73 per share based on the following assumptions used in the Black-Scholes option pricing model: Expected volatility 128.0 % Expected dividend yield — Expected term (in years) 10 Risk-free interest rate 3.83 % The expected volatility assumption is based on the calculated volatility of our common stock at the date of grant based on historical prices over the most recent period commensurate with the term of the award. The expected dividend yield assumption is based on our history and expected dividend payouts: we have not, and do not expect to, pay dividends. The expected term assumption is the contractual term of the options for non-employees. The risk-free interest rate assumption is determined using the U.S. treasury yields for bonds with a maturity commensurate with the term of the award. The stock-based compensation expense was recorded as follows (in thousands): Three Months Ended Nine Months Ended 2024 2023 2024 2023 Research and development $ 5 $ 3 $ 13 $ 12 Selling, general and administrative (1) 68 128 233 455 Total stock-based compensation expense $ 73 $ 131 $ 246 $ 467 (1) Includes $44,000 and $100,000 related to stock issued in exchange for marketing services for the three and nine month periods ended September 30, 2023. The allocation between research and development and selling, general and administrative expense was based on the department and services performed by the employee or non-employee. At September 30, 2024, the total compensation cost related to unvested options not yet recognized was $439,000, which will be recognized over a weighted average period of 2.0 years, assuming the employees and non-employees complete their service period required for vesting.

The original warrants consisted of 48,911 shares issued August 24, 2023 with an exercise price of $86.40 per share and a weighted average remaining life of 2.1 years (the “August 2023 Original Warrants”) and 456,591 shares issued November 29, 2023 with an exercise price of $13.00 per share and a weighted average remaining life of 2.5 years (the “November 2023 Original Warrants”) (collectively, the “Original Warrants”). The Original Warrants were exercised for $4.60 per share for gross proceeds of $2.3 million, before deducting $340,000 of issuance costs. Of the 505,502 shares issued, 8,293 shares were held in abeyance as of September 30, 2024 and not considered outstanding until certain conditions are met, at which time such shares will become outstanding. The balance of the shares in abeyance will be held in abeyance until notice from the stockholder that the balance, or portion thereof, may be issued in compliance with a beneficial ownership limitation provision in the warrants. Such shares were released from abeyance in October. In connection with the Warrant Inducement transaction, new warrants to purchase 1,036,279 shares of our common stock were issued, which are discussed in Note 7. In June 2024, we entered into an at-the-market offering arrangement with a sales agent, pursuant to which we may offer and sell, from time to time at our sole discretion, in transactions that are deemed to be “at the market” offerings under the Securities Act of 1933, as amended (the “Securities Act”), shares of our common stock for aggregate gross proceeds of up to $1,575,944 (“ATM Facility”). The offer and sale of shares will be made pursuant to a previously filed shelf registration statement on Form S-3 (Registration no. 333-261227), originally filed with the SEC on November 19, 2021 and amended on May 4, 2022, and declared effective by the SEC on May 6, 2022, and the related prospectus supplement related to the offering of shares dated June 20, 2024, and filed with the SEC on such date pursuant to Rule 424(b) under the Securities Act. As of September 30, 2024, we have not sold any shares under this ATM Facility and there are 315,189 shares of common stock reserved for potential issuance under the ATM Facility.

These warrants are exercisable immediately with an exercise price of $4.35 per share, with 571,318 expiring August 23, 2029 (5-Year New Warrants) and 439,686 expiring February 23, 2026 (18-Month New Warrants). We estimated the fair value of the 5-Year New Warrants to be $1.9 million using a Black-Scholes model based on the following significant inputs: common stock price of $4.10 per share; volatility of 118%; term of 5 years; dividend yield of 0%; and risk-free rate of 3.6%. The fair value of the 18-Month New Warrants was estimated to be $1.2 million using the Black-Scholes model based on the following significant inputs: common stock price of $4.10 per share; volatility of 153%; term of 1.5 years; dividend yield of 0%; and risk-free rate of 4.1%. • In August, placement agent warrants were issued to purchase up to 25,275 shares of our common stock. The placement agent warrants are exercisable immediately upon issuance, with an exercise price per share of $5.75 per share, and expire August 23, 2029. We estimated the fair value of these warrants to be $83,000 using a Black-Scholes model based on the following significant inputs: common stock price of $4.10 per share; volatility of 118%; term of 5 years; dividend yield of 0%;and risk-free interest rate of 3.6%. • In August, the Original Warrants representing 505,502 shares of common stock were exercised for $4.60 per share. The terms of the Original Warrants were modified in order to induce exercise. See Warrant Inducement discussion in Note 6. The difference between the fair value of the warrants immediately prior to modification and immediately after modification was $386,000 using the Black-Scholes model based on the following significant inputs: ◦ For the August 2023 Original Warrants related to 48,911 shares: common stock price of $4.10 per share; volatility of 151%; term of 2.1 years; dividend yield of 0%; and risk-free rate of 3.9%; and ◦ For the November 2023 Original Warrants related to 456,591 shares: common stock price of $4.10 per share; volatility of 140%; term of 2.5 years; dividend yield of 0%; and risk-free rate of 3.8%. • In January, warrants representing 460 shares of common stock were exercised with an exercise price of $13.00 per share.

The accompanying financial statements and notes thereto give retrospective effect to the reverse stock split for all periods presented. All issued and outstanding common stock, options and warrants exercisable for common stock and per share amounts contained in our financial statements have been retrospectively adjusted.

Certain warrant holders were induced to exercise warrants by reducing the exercise price to the then current market price of our common stock (the “Warrant Inducement”). The original warrants consisted of 48,911 shares issued August 24, 2023 with an exercise price of $86.40 per share and a weighted average remaining life of 2.1 years (the “August 2023 Original Warrants”) and 456,591 shares issued November 29, 2023 with an exercise price of $13.00 per share and a weighted average remaining life of 2.5 years (the “November 2023 Original Warrants”) (collectively, the “Original Warrants”).

Such shares were released from abeyance in October. In connection with the Warrant Inducement transaction, new warrants to purchase 1,036,279 shares of our common stock were issued, which are discussed in Note 7. In June 2024, we entered into an at-the-market offering arrangement with a sales agent, pursuant to which we may offer and sell, from time to time at our sole discretion, in transactions that are deemed to be “at the market” offerings under the Securities Act of 1933, as amended (the “Securities Act”), shares of our common stock for aggregate gross proceeds of up to $1,575,944 (“ATM Facility”).

LOSS PER SHARE

LOSS PER SHARE	9 Months Ended
	Sep. 30, 2024
Earnings Per Share [Abstract]
LOSS PER SHARE	LOSS PER SHARE Basic loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period, which includes prefunded warrants and shares held in abeyance from date of issuance. Diluted loss per share is computed by dividing the loss attributable to common stockholders by the weighted average number of common shares used in the basic loss per share calculation plus potentially dilutive securities outstanding during the period determined using the treasury stock method. Stock options and warrants are considered to be potentially dilutive securities but have been excluded from the calculation of diluted loss per share because their effect would be anti-dilutive given the net losses reported for all periods presented. Therefore, basic and diluted loss per share are the same for each period presented. The following shares were excluded from the calculation of diluted net loss per share: Three Months Ended Nine Months Ended 2024 2023 2024 2023 Common stock warrants — 25,938 370,326 327,751 Stock options 43,889 — 84,293 4,283 43,889 25,938 454,619 332,034

Use of Estimates	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 inventory, common stock warrants, and stock-based awards, such as stock options and restricted stock units. Actual results could differ from such estimates.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and were $58,000 and $57,000 for the three months ended September 30, 2024 and 2023, respectively, and $180,000 and $147,000 for the nine months ended September 30, 2024 and 2023, respectively.
