NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1: 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 populations, through fertility control. Our current products are known as ContraPest® and EvolveTM.

Our initial product was ContraPest, which 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 of which have approved the removal of the Restricted Use designation, as well as the District of Columbia and five major U.S. territories.

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, Section 25(b) (“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 43 states.

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 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 32 states.

Going Concern

Our condensed financial statements as of June 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.

Table of Contents

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 June 30, 2024, we had an accumulated deficit of $133.3 million and cash and cash equivalents of $2.0 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.

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. Also, see Note 10.

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 June 30, 2024, and our operating results and cash flows for the six month periods ended June 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.

Table of Contents

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 was $62,000 and $43,000 for the three months ended June 30, 2024 and 2023, respectively, and $121,000 and $84,000 for the six months ended June 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.

NOTE 2: BALANCE SHEET COMPONENTS

Cash and Cash Equivalents

NOTE 5: 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, we only have stock options 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 immediately, or ratably over a 12- to 36-month period coinciding with their respective service periods, with terms generally of five years. Certain stock option awards provide for accelerated vesting upon a change in control.

We have 203,311 shares of common stock available for issuance under the 2018 Plan, which includes the increase to the total number of authorized shares of 200,000 shares approved by our stockholders on July 11, 2024.

Table of Contents

The following table presents the outstanding stock option activity:


	Number of Options		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Term (years)
Three months ended June 30, 2024:
Outstanding as of March 31, 2024	3,641		$	1,194.90	3.8
Granted	892		6.740		4.8



Outstanding as of June 30, 2024	4,533	(1)	899.48		3.8
Six months ended June 30, 2024:
Outstanding as of December 31, 2023	3,643		1,197.00		4.0
Granted	892		6.740		4.8

Forfeited	(2)		1,965.36		3.0

Outstanding as of June 30, 2024	4,533	(1)	899.48		3.8
Exercisable as of June 30, 2024	3,987		1,009.40		3.8

(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 three months ended June 30, 2024 was $5.59 per share, based on the following assumptions used in the Black-Scholes option pricing model:


Expected volatility	117.0	%
Expected dividend yield	—
Expected term (in years)	5
Risk-free interest rate	4.43	%

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 June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Research and development	$	4	$	5	$	8	$	9
Selling, general and administrative (1)	84		165		165		327
Total stock-based compensation expense	$	88	$	170	$	173	$	336

(1) Includes $56,000 related to stock issued in exchange for marketing services for the three and six month periods ended June 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 June 30, 2024, the total compensation cost related to unvested options not yet recognized was $124,000, which will be recognized over a weighted average period of 1.1 years, assuming the employees and non-employees complete their service period required for vesting.

NOTE 8: 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:

NOTE 10: SUBSEQUENT EVENTS

On July 11, 2024, we held our annual meeting of stockholders (the “Annual Meeting”), at which meeting our stockholders approved an amendment to our 2018 Plan. The effect of the amendment to the 2018 Plan is to increase the number of shares of common stock available under the 2018 Plan by 200,000 shares.

On July 11, 2024, our stockholders also approved a proposal at our Annual Meeting further amending our Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), to effect a reverse stock split of our common stock at a ratio between one-for-two (1:2) and one-for-twenty (1:20), without reducing the authorized number of shares of common stock. On July 11, 2024, our board of directors approved a final split ratio of one-for-ten (1:10). Following such approval, we filed an amendment to the Certificate of Incorporation with the Secretary of the State of Delaware on July 23, 2024 to effect the reverse stock split, with an effective date of July 24, 2024.

We have evaluated subsequent events from the balance sheet date through August 8, 2024, the date at which the condensed financial statements were issued, and determined that there were no additional items that require adjustment to or disclosure in the condensed financial statements.

Overview

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. Although sales of our product have increased over the last three years, 17% in 2023, 77% in 2022 and 123% in 2021, we are not yet able to fund operations by product sales alone. 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 generated limited revenue from research grants and licensing fees received under former license agreements.

Through June 30, 2024, we received net proceeds of $101.8 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 $4.6 million in net product sales. As of June 30, 2024, we had an accumulated deficit of $133.3 million and cash and cash equivalents of $2.0 million.

We have incurred significant operating losses every year since our inception, with a net loss of $1.6 million for the three months ended June 30, 2024. We expect to continue to incur significant expenses and generate operating losses for at least the next six months.

Table of Contents

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 and internationally, 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.

Revenues

Sales, net of sales discounts and promotions, were $459,000 for the second quarter of 2024, compared to $305,000 for the second quarter of 2023. The $154,000 increase was driven by the launch of our latest products partially offset by a decrease in the number of units sold of our existing Elevate Bait System product offering. Launched in January 2024, Evolve is a soft bait containing the active ingredient cottonseed oil and represented approximately 58%, or $266,000, of revenues for the second quarter of 2024. Launched in August 2023, Isolate Bait System is a liquid bait and represented 8%, or $37,000, of revenues for the second quarter of 2024. Partially offsetting these increases was a decline in revenue in the second quarter of 2024 when compared with the second quarter of 2023, resulting from a decline in the number of units sold of our existing Elevate Bait System product offering. Limited erosion of demand for ContraPest products is expected as Evolve products are accepted in the marketplace.

For the six months ended June 30, 2024, sales were $874,000, compared to $538,000 for the six months ended June 30, 2023. The $336,000 increase was driven by our latest products, Evolve, which represented approximately 59%, or $519,000, and Isolate Bait System, which represented approximately 8%, or $67,000, of revenues for the first half of 2024. These increases were offset by a decrease related to a lower number of units sold of our existing Elevate Bait System product offering in the first half of 2024 when compared with the first half of 2023.

Cost of Sales

Cost of sales consists of costs related to products sold, including scrap and reserves for obsolescence, as well as shipping costs when charged to the customer. Cost of sales was $210,000, or 45.8% of net sales, for the second quarter of 2024, compared to $163,000, or 53.6% of net sales, for the second quarter of 2023. The lower cost of net sales is largely due to a

Table of Contents

shift in the mix of products sold, and declined largely driven our latest product offering, Evolve, which launched in January 2024. Shipping costs, which impacts gross profit margin, was 8.4% and 4.7% of net sales in the second quarter of 2024 and 2023, respectively. Excluding shipping costs, cost of sales would have been $172,000, or 40.8% of net sales in the second quarter of 2024, compared with $149,000, or 51.1% of net sales in the second quarter of 2023..

For the six months ended June 30, 2024, cost of sales was $490,000, or 56.1% of net sales, compared to $304,000, or 56.5% of net sales, for the six months ended June 30, 2023. Cost of sales in the first half of 2024 was impacted during the first few months of 2024 from the higher cost of a key ingredient for our new Evolve product, as we transitioned from development-stage raw materials pricing to production-level raw materials pricing. Cost of sales in the first half of 2023 was impacted by the scrapping of defective trays no longer used in our products in the first quarter of 2023.

Gross Profit

Gross profit for the second quarter of 2024 was $249,000, for a gross profit margin of 54.2%, compared to a gross profit of $142,000, or a gross profit margin of 46.4%, for the second quarter of 2023. Higher gross profit margin was driven by a shift in the mix of products sold, and increased due to our latest product offering Evolve, which launched in January 2024. This increase was partially offset by lower gross profit margin related to a shift in the mix of sales through our sales channels, with higher sales to distributors in the second quarter of 2024 when compared with the second quarter of 2023.

For the six months ended June 30, 2024, gross profit was $384,000, for a gross profit margin of 43.9%, compared to $234,000, gross profit margin of 43.5%, for the six months ended June 30, 2023. The gross profit margin in the first half of 2024 was impacted by both the higher-than-expected cost of a key ingredient in our new Evolve product, combined with an increased proportion of our sales coming from distributors. The gross profit margin in the first half of 2023 was impacted by the higher cost of sales related to the scrapping of defective tanks during no longer used in our products.

Research and Development Expenses

Research and development expenses consisted of the following (in thousands):


	Three Months Ended June 30,				Increase (Decrease)		Six Months Ended June 30,				Increase (Decrease)
	2024		2023				2024		2023
Personnel (including stock-based compensation)	$	330	$	214	$	116	$	528	$	456	$	72

Other	3		12		(9)		44		26		18
Total	$	467	$	381	$	86	$	837	$	768	$	69

Research and development expenses were $467,000 for the second quarter of 2024, compared to $381,000 for the second quarter of 2023. The $86,000 increase was primarily due to the realignment of the focus of our field development personnel to research and development activities, lower overhead allocation, and increased costs related to the expansion of facilities and supplies and maintenance related to research and development efforts. These increases were partially offset by lower consulting and legal fees required for research and development purposes, combined with lower expenses overall related to field and product improvement studies in the second quarter of 2024 when compared with the second quarter of 2023.

For the six months ended June 30, 2024, research and development expenses were $837,000, compared to $768,000 for the six months ended June 30, 2023. The $69,000 increase was primarily due to the realignment of the focus of our field development personnel to research and development activities, lower overhead allocation, and increased costs related to the expansion of facilities and supplies and maintenance related to research and development efforts. These increases were partially offset by lower consulting and legal fees required for research and development purposes, combined with lower expenses overall related to field and product improvement studies in the first half of 2024 when compared with the first half of 2023.

Selling, general and administrative expenses were $1.4 million for the second quarter of 2024, as compared to $1.8 million for the second quarter of 2023. The decrease of $377,000 was primarily due to lower personnel-related expenses resulting from both lower headcount and stock-based compensation, combined with lower professional fees and insurance costs. Consulting fees related to marketing efforts are lower in the second quarter of 2024 when compared with the second quarter of 2023 due to changes in our overall marketing program and lower legal fees. The changes in legal fees are due to the settlement of a legal matter in November 2023. Additionally, our insurance cost is lower resulting from both policy and rate changes. In the second quarter of 2023, personnel costs included severance costs of $119,000 related to the termination of our former Chief Revenue Officer.

For the six months ended June 30, 2024, selling, general and administrative expenses were $3.0 million, compared to $3.5 million for the six months ended June 30, 2023. The $519,000 decrease was primarily due to lower personnel-related expenses resulting from both lower headcount and stock-based compensation, combined with lower professional fees and insurance costs. Consulting fees related to marketing efforts are lower in the first half of 2024 when compared with the first half of 2023 due to changes in our overall marketing program and lower legal fees. The changes in legal fees are due to the settlement of a legal matter in November 2023. Additionally, our insurance cost is lower resulting from both policy and rate changes. In the second quarter of 2023, personnel costs includes severance costs of $119,000 related to the termination of our former Chief Revenue Officer.

Other Income, Net

Other income, net for the second quarter of 2024 consisted of interest income of $22,000, partially offset by interest expense of $5,000, compared with the second quarter of 2023, which consisted of interest income of $7,000.

Interest income was higher due to a combination of a higher average balance of cash and cash equivalents and a higher interest rate during the second quarter of 2024 when compared with the second quarter of 2023. Interest expense in the second quarter of 2024 relates to the notes payable entered into beginning in late 2023 for the purchase of certain equipment.

For the six months ended June 30, 2024, other income, net, consisted of interest income of $37,000, partially offset by interest expense of $9,000, compared with the six months ended June 30, 2023, which consisted of interest income of $15,000. The higher interest income was due to a combination of a higher average balance of cash and cash equivalents and higher interest rate in the first half of 2024 when compared to the first half of 2023.

Liquidity and Capital Resources

Liquidity

Since our inception, we have sustained significant operating losses in the course of our research and development activities and commercialization efforts 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. 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; and debt financing, consisting primarily of convertible notes.

Through June 30, 2024, we have received net proceeds of $101.8 million from our sales of common stock, preferred stock and warrant exercises and issuance of convertible and other promissory notes, an aggregate of $4.6 million in net product sales and an aggregate of $1.7 million from licensing fees. As of June 30, 2024, we had an accumulated deficit of $133.3 million and cash and cash equivalents of $2.0 million.

Our ultimate success depends upon the outcome of a combination of factors, including the following: (i) successful commercialization of our fertility control products and maintaining and obtaining regulatory approval of our products and product candidates; (ii) market acceptance, commercial viability and profitability of our fertility control products and any 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 activities; (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 June 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 three months. We have evaluated and will continue to evaluate our operating expenses and will concentrate our resources toward the successful commercialization of our fertility control products in the United States and internationally. 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 months, and we are unable to raise the 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.

Additional Funding Requirements

We expect our expenses to continue or increase in connection with our ongoing activities, particularly as we focus on marketing and sales of fertility control products. In addition, we will continue to incur costs associated with operating as a public company.

In particular, we expect to incur substantial and increased expenses as we:

•work to maximize market acceptance for, and generate sales of, our products, including by conducting field demonstrations for potential lead customers;

•explore strategic partnerships to enable us to penetrate additional target markets and geographical locations;

•manage the infrastructure for sales, marketing and distribution of fertility control products and any other product candidates for which we may receive regulatory approval;

•seek additional regulatory approvals for fertility control products, including to more fully expand the market and use for fertility control products and, if we believe there is commercial viability, for our other product candidates;

•further develop our manufacturing processes to contain costs while being able to scale to meet future demand of fertility control products and any other product candidates for which we receive regulatory approval;

Table of Contents

•continue product development of fertility control products and advance our research and development activities and, as our operating budget permits, advance the research and development programs for other product candidates;

•maintain and protect our intellectual property portfolio; and

•add operational, financial and management information systems and personnel, including personnel to support our product development and commercialization efforts and operations as a public company.

We will need additional financing to fund these continuing and additional expenses.

The following table summarizes our sources and uses of cash for each of the periods presented (in thousands):


	Six Months Ended June 30,
	2024		2023
Cash and cash equivalents, beginning of period	$	5,395	$	4,775

Cash Flows from Operating Activities—Cash flows from operating activities are generally determined by the amount and timing of cash received from customers and payments made to vendors, as well as the nature and amount of non-cash items, including depreciation and amortization and stock-based compensation included in operating results during a given period.

During the six months ended June 30, 2024, operating activities used $3.4 million of cash, resulting from our net loss of $3.4 million and net changes in our operating assets and liabilities of $248,000, partially offset by net non-cash charges of $248,000, consisting primarily of stock-based compensation and depreciation and amortization expense. Our net loss was driven by costs related to our selling, general and administrative activities resulting from our continued efforts to commercialize our products, combined with research and development costs related to our continued efforts on formulations of new products and improvements to existing products. Net cash used by changes in our operating assets and liabilities consisted primarily of increases in accounts receivable of $150,000, inventory of $104,000 and prepaid expenses of $76,000, partially offset by an increase in accounts payable and accrued expenses of $88,000.

During the six months ended June 30, 2023, operating activities used $3.8 million of cash, resulting from our net loss of $4.0 million, partially offset by net changes in our operating assets and liabilities of $130,000 and by non-cash charges of $403,000, consisting primarily of stock-based compensation and depreciation and amortization expense. Our net loss was driven by costs related to our selling, general and administrative activities resulting from our efforts to commercialize our products, combined with costs related to our research and development efforts. Net cash used by changes in our operating assets and liabilities consisted of a net decreases in accounts payable and accrued expenses of $359,000, partially offset by decreases in prepaid expenses of $92,000, inventory of $88,000, and accounts receivable of $71,000.

Cash Flows from Investing Activities—Cash flows used in investing activities primarily consist of the purchase of property and equipment, offset by any proceeds received in connection with sales of property and equipment. During the six months ended June 30, 2024 and 2023, cash flows used in investing activities consisted of property and equipment purchases.

Cash Flows from Financing Activities—Financing activities provide cash for both day-to-day operations and capital requirements as needed. During the six months ended June 30, 2024, net cash provided by financing activities consisted of proceeds received from notes payable of $25,000, proceeds received from the exercise of warrants of $6,000, partially offset by repayments on notes payable of $17,000. During the six months ended June 30, 2023, net cash provided by

BASIS OF PRESENTATION	6 Months Ended
BASIS OF PRESENTATION	Jun. 30, 2024
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 populations, through fertility control. Our current products are known as ContraPest® and EvolveTM. Our initial product was ContraPest, which 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 of which have approved the removal of the Restricted Use designation, as well as the District of Columbia and five major U.S. territories. 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, Section 25(b) (“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 43 states. 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 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 32 states. Going Concern Our condensed financial statements as of June 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 June 30, 2024, we had an accumulated deficit of $133.3 million and cash and cash equivalents of $2.0 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 June 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 three 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. Also, see Note 10. 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 June 30, 2024, and our operating results and cash flows for the six month periods ended June 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 was $62,000 and $43,000 for the three months ended June 30, 2024 and 2023, respectively, and $121,000 and $84,000 for the six months ended June 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.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On July 11, 2024, we held our annual meeting of stockholders (the “Annual Meeting”), at which meeting our stockholders approved an amendment to our 2018 Plan. The effect of the amendment to the 2018 Plan is to increase the number of shares of common stock available under the 2018 Plan by 200,000 shares. On July 11, 2024, our stockholders also approved a proposal at our Annual Meeting further amending our Amended and Restated Certificate of Incorporation (as amended, the “Certificate of Incorporation”), to effect a reverse stock split of our common stock at a ratio between one-for-two (1:2) and one-for-twenty (1:20), without reducing the authorized number of shares of common stock. On July 11, 2024, our board of directors approved a final split ratio of one-for-ten (1:10). Following such approval, we filed an amendment to the Certificate of Incorporation with the Secretary of the State of Delaware on July 23, 2024 to effect the reverse stock split, with an effective date of July 24, 2024. We have evaluated subsequent events from the balance sheet date through August 8, 2024, the date at which the condensed financial statements were issued, and determined that there were no additional items that require adjustment to or disclosure in the condensed financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed Financial Statements	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 June 30, 2024, and our operating results and cash flows for the six month periods ended June 30, 2024 and 2023.
Recent Accounting Pronouncements	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	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.
Comprehensive Loss	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.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and was $62,000 and $43,000 for the three months ended June 30, 2024 and 2023, respectively, and $121,000 and $84,000 for the six months ended June 30, 2024 and 2023, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents Highly liquid investments with maturities of three months or less as of the date of acquisition are classified as cash equivalents, of which we had $2.0 million and $5.4 million as of June 30, 2024 and December 31, 2023, respectively, included within cash and cash equivalents in the condensed balance sheets.
