Overview

We are a clinical-stage biotechnology company developing next-generation cell and gene therapies engineered with our gene circuit platform technologies for patients living with incurable diseases. Our mission is to create a new generation of smarter medicines that outsmart complex diseases using novel and unprecedented approaches. To accomplish this mission, we have built a synthetic biology platform that we believe may enable us to program next-generation cell and gene therapies with gene circuits. These gene circuits, which we created from novel and proprietary combinations of DNA sequences, are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their respective cellular environments. Using gene circuits, our product candidates are designed to precisely kill cancer cells, spare healthy cells, increase specificity to target cells and control the expression of drugs even after administration.

We are applying our gene circuit technologies to develop a pipeline of medicines that use chimeric antigen receptor (“CAR”) white blood cells with the goal of addressing major challenges and providing potentially lifesaving treatments for people living with cancer. Our lead product candidates utilize off-the-shelf healthy adult donor derived natural killer (“NK”) cells to create CAR-NK cells outfitted with gene circuit technologies in several oncology indications with high unmet need.

We have incurred net losses of $4.2 million and $14.1 million for the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and December 31, 2025, we had cash and cash equivalents of $8.9 million and $16.4 million, respectively, and an accumulated deficit of $362.8 million and $358.6 million, respectively. Net cash flows used in operating activities were $7.5 million and $14.1 million during the three months ended March 31, 2026 and 2025, respectively. Substantially all of our net losses resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur significant losses for the foreseeable future.

We anticipate that our expenses and operating losses will increase substantially over the foreseeable future. The expected increase in expenses will be driven in large part by our ongoing activities, if and as we:

• continue to advance our gene circuit platform technologies;
• continue preclinical development of our current and future product candidates and initiate additional preclinical studies;
• fund clinical development of our current product candidates;
• commence clinical studies of our future product candidates;
• fund manufacturing of our current and future product candidates;
• seek regulatory approval of our current and future product candidates;
• expand our operational, financial, and management systems and increase personnel, including personnel to support our preclinical and clinical development, manufacturing and commercialization efforts;
• continue to develop, grow, maintain, enforce and defend our intellectual property portfolio; and
• incur additional legal, accounting, or other expenses in operating our business, including costs associated with operating as a public company.

Recent Developments

Lease Amendment and GeneFab Sublease Matters

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, GeneFab was in default under the GeneFab Alameda Sublease and the GeneFab HQ Sublease, and we were in default under the Alameda Lease for nonpayment of rent.

In March 2026, we entered into a series of agreements with our Alameda Landlord and GeneFab to restructure the Alameda Lease and related sublease arrangements and to cure the existing defaults.

On March 17, 2026, we entered into the Alameda Lease Amendment with the Alameda Landlord, pursuant to which we reduced the leased premises from approximately 92,000 rentable square feet to approximately 46,000 rentable square feet. The Alameda Lease Amendment also reduced our future base rent obligations for the remaining term of the lease and modifies certain cost-sharing arrangements with respect to operating expenses, taxes, and utilities. In connection with the Alameda Lease Amendment, the Alameda Landlord is entitled to draw $2.0 million under our existing letter of credit, and the required letter of credit for the remainder of the lease term was reduced to approximately $0.8 million. In May 2026, the Alameda Landlord drew the $2.0 million under the Company’s letter of credit.

In connection with the Alameda Lease Amendment, on March 17, 2026, we entered into the GeneFab Alameda Sublease Amendment with GeneFab, and pursuant to which, the subleased premises were reduced to approximately 46,000 rentable square feet. The GeneFab Alameda Sublease Amendment revised the base rent, operating expenses, taxes and utilities owed by GeneFab to equal the amounts owed by us under the Alameda Lease Amendment. GeneFab also agreed to pay a $1.0 million Reduction Fee (as defined in Note 5) to the Alameda Landlord pursuant to the terms and conditions of the Consent Amendment (as defined in Note 5).

On March 9, 2026, we entered the GeneFab HQ Sublease Amendment with GeneFab, pursuant to which we accelerated the end of the HQ Lease, effective March 31, 2026. As part of this agreement, GeneFab paid all past-due sublease rent for the GeneFab HQ Sublease and no longer subleases premises under the HQ Lease from the us as of March 31, 2026.

On March 17, 2026,we entered into the GeneFab Letter Agreement with GeneFab in connection with the lease and sublease amendments described above. The GeneFab Letter Agreement provides back rent payment of $1.4 million that may be satisfied, in whole or in part, through a cash prepayment credit to be applied toward work or services to be performed by GeneFab for us under the 2024 Amended and Restated DMSA, that we may access such prepayment credit immediately and that any unpaid portion must be paid in immediately available funds by September 1, 2026. The GeneFab Letter Agreement further provides that we may access $2.0 million as a prepayment credit to be applied toward work or services to be performed by GeneFab for us under the 2024 Amended and Restated DMSA beginning September 1, 2026. This prepayment credit represents a portion of the agreed-upon settlement of past-due sublease rent. GeneFab’s failure to perform its obligations with respect to the outstanding rent or the $2.0 million prepayment credit constitutes an immediate event of default under the GeneFab Alameda Sublease Amendment. The GeneFab Letter Agreement terminates automatically once the applicable prepayment credits have been fully applied.

As a result of these transactions, the Alameda lease default and the GeneFab sublease defaults were cured.

Holding Company Reorganization

On April 24, 2026, we completed a holding company reorganization (the “Reorganization”) pursuant to which the Company became the successor issuer to Senti Biosciences, Inc. (“Former Senti”) and Former Senti became a direct, wholly owned subsidiary of Senti Holdings, Inc., a direct wholly owned subsidiary of the Company. The Reorganization did not result in any change to our consolidated operations, assets, liabilities, management or the Board of Directors.

Securities Purchase Agreement

On April 27, 2026, we entered into a securities purchase agreement with an accredited investor affiliated with Celadon, pursuant to which our wholly owned subsidiary, Senti Holdings, Inc. may issue up to $40.0 million aggregate principal amount of senior secured convertible notes in up to two tranches, subject to specified closing conditions. The initial tranche consists of $10.0 million, with an additional tranche of up to $30.0 million subject to the investor’s election and certain additional conditions. Upon issuance, the Notes may be converted for shares of Senti Holdings’ common stock or, subject to stockholder approval, exchanged for shares of our common stock, in each case, initially at a price of $0.6261 per share, subject to customary adjustments and a full-ratchet anti-dilution adjustment if we issue or sell common stock at a price below the exchange/conversion price then in effect. If the initial tranche is issued, we expect to receive net proceeds of $9.7 million.

The net proceeds from the transaction, if completed, are expected to be used for general corporate purposes, including advancing clinical and manufacturing activities for SENTI-202.

Components of Results of Operations

Collaboration Revenue - Related Party

We currently have no products approved for sale, and we have never generated any revenue from the sale of any products. For the three months ended March 31, 2026, collaboration revenue related to an option exercise period extension fee under our Collaboration and Option Agreement (“BlueRock Agreement”) with BlueRock Therapeutics LP (“BlueRock”) and was recognized ratably over the extension period. BlueRock is a related party to us. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 12—Related Parties” in this Report for details.

Operating Expenses

Our operating expenses consist of research and development expenses, and general and administrative expenses.

Research and Development Expenses

Research and development costs consist primarily of costs incurred for the discovery, and preclinical and clinical development of our product candidates, which include:

• employee-related expenses, including salaries, related benefits, and stock-based compensation expenses for employees engaged in research and development functions;
• expenses incurred in connection with research, laboratory consumables, and clinical and preclinical studies;
• the cost of consultants engaged in research and development, regulatory, and clinical related services
• the cost to develop our manufacturing process and manufacturing product candidates for use in our research, preclinical studies and clinical trials, including under agreements with third parties, such as consultants, contractors and third-party contract manufacturing organizations, or CMOs;
• facilities, depreciation and other expenses, which include allocated expenses for rent and maintenance of facilities, insurance and supplies;
• costs related to regulatory compliance; and
• the cost of annual license fees.

We have not historically tracked research and development expenses by program, with the exception of third-party research projects. Our internal resources, employees and infrastructure are not directly tied to any one research project or product candidate and are typically deployed across multiple projects. As such, we do not maintain information regarding these costs incurred for these early-stage research and product candidate discovery programs on a project-specific basis.

Our direct external development program expenses reflect external costs attributable to our preclinical development candidates selected for further development as well as INDs and clinical development activities. Such expenses include third-party contract costs relating to manufacturing, clinical trial activities, translational medicine and toxicology activities. We do not allocate internal research and development costs which include personnel, facility costs, laboratory consumables and discovery and research related activities associated with our pipeline because these costs are deployed across multiple programs and our platform, and, as such, are not separately classified.

Research and development expenses consisted of the following:

Research and development activities are central to our business model. There are numerous factors associated with the successful commercialization of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. In addition, future regulatory factors beyond our control may impact our preclinical development programs. Product candidates in clinical development generally have higher development costs than those in preclinical stages of development, primarily due to the increased size and duration of clinical trials. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical development of any of our product candidates. However, we expect that our research and development expenses and manufacturing costs will increase in connection with our planned preclinical and clinical development activities in the near term and in the future.

The successful development of our current and future product candidates is highly uncertain. This is due to numerous risks and uncertainties, including the following:

• negative or inconclusive results from our preclinical studies or clinical trials or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional preclinical studies or clinical trials or abandon any or all of our programs;
• product-related side effects experienced by participants in our clinical trials or by individuals using therapeutics similar to our product candidates;
• delays in submitting IND applications or comparable foreign applications, or delays or failures to obtain the necessary approvals from regulators to commence a clinical trial, or a suspension or termination of a clinical trial once commenced;
• conditions imposed by the FDA or other regulatory authorities regarding the scope or design of our clinical trials;
• delays in enrolling research subjects in clinical trials;
• high drop-out rates of research subjects;
• inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;
• Chemistry, manufacturing and control (“CMC”) challenges associated with manufacturing and scaling up biologic product candidates to ensure consistent quality, stability, purity and potency among different batches used in clinical trials;
• greater-than-anticipated clinical trial costs;
• poor potency or effectiveness of our product candidates during clinical trials;
• unfavorable FDA or other regulatory authority inspection and review of a clinical trial or manufacturing site;
• failure of our third-party contractors or investigators to comply with regulatory requirements or otherwise meet their contractual obligations in a timely manner, or at all;
• delays and changes in regulatory requirements, policies and guidelines; and
• the FDA or other regulatory authorities interpret our data differently than we do.

A change in the outcome of any of these variables may significantly impact the costs and timing associated with the development of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation for personnel in executive, finance and other administrative functions. Other significant costs include legal fees relating to corporate matters, professional fees for accounting and consulting services, insurance and an allocation of facility-related costs.

General and administrative expenses consisted of the following:

Results of Operations

Comparison of the Three Months Ended March 31, 2026 and 2025

The following table summarizes our results of operations for the three months ended March 31, 2026 and 2025:

(in thousands)

Collaboration revenue - related party. For the three months ended March 31, 2026, collaboration revenue related to an option exercise period extension fee under the BlueRock Agreement with a related party and was recognized ratably over the extension period. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 12—Related Parties” in this Report for details.

Research and development expenses. Research and development expenses were $5.3 million and $9.3 million for the three months ended March 31, 2026 and 2025, respectively. The decrease of $4.0 million was primarily due to a decrease of $4.0 million in external services and supplies cost.

General and administrative expenses. General and administrative expenses were $6.2 million and $7.1 million for the three months ended March 31, 2026 and 2025, respectively. The decrease of $0.9 million was primarily due to a decrease of $0.7 million in external services and supplies cost, a decrease of $0.2 million in depreciation and amortization, and a decrease of $0.1 million in facilities and other cost, partially offset by an increase of $0.1 million in personnel-related expenses, including stock-based compensation.

Gain on lease modification. Gain on lease modification was $6.9 million for the three months ended March 31, 2026. The gain is a one-time income due to the Alameda Lease Amendment. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 5—Operating Leases” in this Report for details.

Interest income. Interest income was $0.1 million and $0.4 million for the three months ended March 31, 2026 and 2025, respectively. The decrease is attributed to lower average cash balances in the relevant periods.

GeneFab sublease income - related party. GeneFab sublease income - related party was $0.1 million and $1.7 million for the three months ended March 31, 2026 and 2025, respectively. The decrease was due to the Alameda Lease Amendment. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—

Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 5—Operating Leases” in this Report for details.

Other income, net. Other income, net remained relatively consistent period over period, and fluctuations were not material.

Liquidity and Capital Resources

Sources of Liquidity

We do not have any products approved for sale and have not generated any revenue from product sales or otherwise. We have incurred net losses and negative cash flows from operations since our inception and anticipate we will continue to incur net losses for the foreseeable future. As of March 31, 2026, we had $8.9 million in cash and cash equivalents, and an accumulated deficit of $362.8 million.

We will need substantial additional funding to support our continuing operations and pursue our development strategy. Until such time as we can generate significant revenue from sales of our product candidates, if ever, we expect to finance our operations through the sale of equity, debt financings or other capital sources, including potential collaborations with other companies or other strategic transactions. Adequate funding may not be available to us on acceptable terms, if at all. Should we fail to raise capital or enter into such agreements as, and when, needed, we may have to significantly delay, scale back, or discontinue the development and commercialization of our product candidates or delay our efforts to expand our product pipeline. As substantial doubt exists about our ability to continue as a going concern, we may also be required to sell or license to other parties’ rights to develop or commercialize our product candidates that we would prefer to retain.

From inception to March 31, 2026, we raised aggregate gross proceeds of $368.6 million from the merger in 2022, the issuance of shares of common stock, the issuance of shares of redeemable convertible preferred stock, the issuance of convertible notes, and, to a lesser extent, through collaboration agreements and governmental grants and loans.

On August 31, 2022, we entered into an Amended and Restated Purchase Agreement (the “A&R Purchase Agreement”) with Chardan Capital Markets LLC (“Chardan”). Pursuant to the A&R Purchase Agreement, we had the right, in our sole discretion, to sell to Chardan up to the lesser of: (i) $50.0 million of shares of our common stock; and (ii) 872,704 shares of common stock at 97% of the volume weighted average price (“VWAP”) of the common stock calculated in accordance with the Purchase Agreement, over a period of 36 months subject to certain limitations and conditions contained in the Purchase Agreement. Sales and timing of any sales of common stock were solely at our election, and we were under no obligation to sell any securities to Chardan under the Purchase Agreement. As consideration for Chardan’s commitment to purchase shares of our common stock at our direction upon the terms and subject to the conditions set forth in the Purchase Agreement, upon execution of the Purchase Agreement, we issued 10,000 shares of our common stock to Chardan and paid a $0.4 million document preparation fee. On March 17, 2025, we terminated the A&R Purchase Agreement. Prior to termination, we issued 384,313 shares of common stock to Chardan under the A&R Purchase Agreement for aggregate net proceeds of $3.0 million.

On March 20, 2025, we entered into the 2025 ATM Agreement with Leerink Partners with respect to an at-the-market offering program under which we may offer and sell, from time to time at our sole discretion, up to a maximum aggregate offering price of $17.5 million of our common stock through Leerink Partners as our sales agent. Under 2025 ATM Agreement, we are not obligated to sell any shares, and either party may suspend or terminate the offering of common stock upon notice to the other party and subject to certain conditions. Leerink Partners will use commercially reasonable efforts, consistent with its normal trading and sales practices, applicable state and federal law, rules and regulations and the rules of The Nasdaq Capital Market, to sell shares from time to time based upon the our instructions, including any price, time or size limits specified by us. We pay Leerink Partners a commission equal to 3.0% of the gross proceeds of any shares of common stock sold, and have agreed to reimburse certain fees and disbursements and provide Leerink Partners with customary indemnification and contribution rights. For the three months ended March 31, 2026 and 2025, no shares were issued under the 2025

ATM Agreement. To date of March 31, 2026, we sold $4,833,477 shares of common stock under the 2025 ATM Agreement at a weighted average price of $2.38 per share, resulting in gross proceeds of $11.5 million and net proceeds of $10.6 million after sales agent commissions and offering costs.

The agreement with CIRM, as described in Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 4—Other Financial Statement information” in this Report is expected to provide us in total a grant of $8.0 million, subject to achievement of certain operational milestones. We received an aggregate of $8.0 million from the CIRM Grant as of both March 31, 2026 and December 31, 2025. The CIRM Grant will help support the ongoing clinical development of SENTI-202.

In December 2024, we issued 21,157 shares of Series A redeemable convertible preferred stock and accompanying warrants to purchase up to 31,735,500 shares of common stock for an aggregate offering price of 47.6 million. On March 10, 2025, we converted the outstanding shares of Series A redeemable convertible preferred stock into 21,157,000 shares of common stock, at the conversion price of $2.25 per share.

Cash Flows

We derived the following summary of our condensed consolidated cash flows for the periods indicated from Part I, Item 1, “Financial Information—Condensed Consolidated Financial Statements (Unaudited)” in this Quarterly Report:

(in thousands)

Operating Activities

For the three months ended March 31, 2026, net cash used in operating activities of $7.5 million was primarily due to our loss of $4.2 million with non-cash adjustments $6.8 million for gain from lease modification, $0.7 million for depreciation and $1.3 million for stock-based compensation expense. Other material changes were comprised of $1.9 million decrease in accounts payables and $2.0 million increase in GeneFab sublease deferred income - related party.

For the three months ended March 31, 2025, net cash used in operating activities of $14.1 million was primarily due to our loss of $14.1 million with non-cash adjustments of $0.9 million for depreciation and $1.2 million for stock-based compensation expense. Other material changes were comprised of $1.1 million decrease in accrued expenses and other current liabilities and $1.1 million decrease in operating lease liabilities.

Investing Activities

For the three months ended March 31, 2026, cash provided by investing activities of $0.1 million relates to the sale of property and equipment.

For the three months ended March 31, 2025, there was no cash provided by or used in investing activities.

Financing Activities

For the three months ended March 31, 2026, cash used in financing activities related to the net settlement of stock awards for employee taxes of $0.1 million.

For the three months ended March 31, 2025, net cash used in financing activities was $0.4 million, primarily due to the payment of issuance costs of $1.9 million, offset by CIRM Grant received of $1.5 million.

Funding Requirements

We concluded that substantial doubt continued to exist and that our cash and cash equivalents of $8.9 million as of March 31, 2026, were not sufficient for us to continue as a going concern for at least one year from the issuance date of the condensed consolidated financial statements. Based on our current operating plan and existing unrestricted cash and cash equivalents, we have determined that we may not be able to maintain current operations starting as early as the second quarter of 2026. As discussed in Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 15— Subsequent Events”, we entered into a securities purchase agreement in April 2026 pursuant to which we expect to receive gross proceeds of $10.0 million in May 2026 upon the closing of the initial tranche of senior secured convertible notes, subject to the satisfaction of specified closing conditions. Assuming receipt of such funding, we currently expect to be able to maintain operations into the third quarter of 2026. Additional funds will be necessary to maintain current operations and to continue research and development activities. Our continued existence is dependent upon management’s ability to raise capital, collect amounts owed to us under existing agreements and ultimately develop profitable operations. While management is devoting substantially all of its efforts to developing our business, raising capital and collecting amounts owed to us under existing agreements, there can be no assurance that our efforts will be successful. Moreover, no assurance can be given that management’s actions will result in raising additional financing or profitable operations.

Our future capital requirements will depend on many factors, including:

• the scope, rate of progress, results and costs of drug discovery, clinical and preclinical development, laboratory testing and clinical trials for our product candidates;
• the number and development requirements of product candidates that we may pursue, and other indications for our current product candidates that we may pursue;
• the costs, timing and outcome of regulatory review of our product candidates;
• our ability to collect amounts owed to us by our sublessee, GeneFab;
• the scope and costs of any commercial manufacturing activities;
• the cost associated with commercializing any approved product candidates;
• the cost and timing of developing our ability to establish sales and marketing capabilities, if any;
• the costs of preparing, filing and prosecuting patent applications, maintaining, enforcing and protecting our intellectual property rights, defending intellectual property-related claims and obtaining licenses to third-party intellectual property;
• the timing and amount of any milestone and royalty payments we are required to make under our present or future license agreements;
• our ability to establish and maintain collaborations on favorable terms, if at all; and
• the extent to which we acquire or in-license other product candidates and technologies and associated intellectual property.

In order to improve our liquidity, management is actively pursuing additional financing. We will need to obtain substantial additional funding for continuing operations. If we are unable to raise capital when needed, or on attractive terms, we could be forced to delay, reduce or eliminate our research or drug development programs or any future commercialization efforts. Although management continues to pursue these plans, there is no assurance that we will be successful in obtaining sufficient funding on terms acceptable to us to fund continuing operations, if at all.

Contractual Obligations and Commitments

We entered into the Alameda Lease Amendment, which reduced the leased premises and corresponding future lease payments. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 5—Operating Leases” in this Report for details on our lease and sublease obligations.

Except as described above, there were no material changes outside of the ordinary course of business in our contractual obligations as of March 31, 2026, from those as of December 31, 2025 as reported in our Annual Report.

Off-Balance Sheet Arrangements

For the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements as defined under the rules and regulations of the SEC.

Critical Accounting Estimates

For three months ended March 31, 2026, there have been no material changes to our critical accounting policies and estimates from those disclosed in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2025.

Emerging Growth Company Status

The JOBS Act permits an emerging growth company to take advantage of an extended transition to comply with new or revised accounting standards applicable to public companies until those standards would otherwise apply to private companies. We are an “emerging growth company” as defined in Section 2(a) of the Securities Act, and have elected to not take advantage of the benefits of this extended transition period.

We expect to remain an emerging growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of the Dynamics Initial Public Offering (“IPO”) (which occurred on May 25, 2021), (b) in which we have total annual revenue of at least $1.235 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of the end of that fiscal year’s second fiscal quarter and our net sales for the year exceed $100 million; and (2) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the preceding, rolling three-year period.

Smaller Reporting Company Status

We are a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will remain a smaller reporting company if (1) the market value of our common stock held by non-affiliates is less than $250 million as of the last business day of the second fiscal quarter, or (2) our annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter are less than $100 million and the market value of our common stock held by non-affiliates is less than $700 million as of the last business day of the second fiscal quarter.

Segment Information

Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision maker in deciding how to allocate resources and assess performance. Our CODM (Chief Executive Officer) views our operations and manages the business as a single operating segment, which is the research and development of our gene circuit platform. Refer to Part I, Item 1. “Condensed Consolidated Financial Statements (Unaudited)—Notes to Condensed Consolidated Financial Statements (Unaudited) —Note 14—Segment Reporting” in this Report for additional information related to operating segment. All long-lived assets are located in the United States. We do not currently generate any revenue.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer, who serves as our principal executive officer, and our Chief Financial Officer, who serves as our principal financial officer and principal accounting officer, to allow timely decisions regarding required disclosure.

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) to determine whether such disclosure controls and procedures provide reasonable assurance that information to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and such information is accumulated and communicated to management, including our principal executive and principal financial officers or persons performing similar functions, as appropriate to allow timely decisions regarding disclosure. Our disclosure controls and procedures were developed through a process in which our management applied its judgment in assessing the costs and benefits of such controls and procedures, which, by their nature, can provide only reasonable assurance regarding the control objectives. You should note that the design of any system of disclosure controls and procedures is based in part upon various assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Changes in Internal Control Over Financial Reporting

During the most recently completed fiscal quarter, there has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Investing in our common stock involves a high degree of risk. Before you decide to invest in common stock, you should consider carefully the risks in Part I, Item 1A of our fiscal year 2025 Annual Report on Form 10-K, together with the other information contained in the Annual Report, including our financial statements and the related notes appearing in this Quarterly Report. We believe the risks described below are the risks that are material to us as of the date of this Quarterly Report. Factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in this Item 1A below. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. If any of the following risks actually occur, our business, results of operations and financial condition would likely be materially and adversely affected. In these circumstances, the market price of our common stock could decline, and you may lose part or all of your investment.

Below we are providing, in supplemental form, new risk factors as well as material changes to our risk factors from those previously disclosed in Part I, Item 1A of our fiscal year 2025 Annual Report on Form 10-K. Our risk factors disclosed in Part I, Item 1A of our fiscal year 2025 Annual Report on Form 10-K provide additional discussion about these supplemental risks.

Risks Related to our Notes Financing

We have entered an agreement to incur indebtedness that may decrease our business flexibility, access to capital, and/or increase our borrowing costs, which may adversely affect our operations and financial results.

In April 2026, we, together with two of our subsidiaries, entered into a securities purchase agreement (the “Securities Purchase Agreement”) with one accredited investor affiliated with our largest stockholder, pursuant to which our wholly owned subsidiary, Senti Holdings, Inc. (“Senti Holdings”), agreed to issue and sell in a private placement up to $40.0 million in aggregate principal amount of its Senior Secured Convertible Notes (the “Notes”) in up to two tranches, subject to the satisfaction of certain specified closing conditions. Upon issuance, the Notes may be converted for shares of Senti Holdings common stock or, subject to stockholder approval, exchanged for shares of our common stock, in each case, initially at a price of $0.6261 per share, which is subject to customary adjustments upon the occurrence of events specified in the Notes. We expect the first tranche of $10.0 million of Notes to be issued in May 2026, subject to the satisfaction of certain specified closing conditions. However, there can be no assurance that any tranche of Notes will be issued on the timeline we expect or at all.

Upon issuance of the Notes, our indebtedness may:

• limit our ability to borrow additional funds for working capital, capital expenditures, acquisitions or other general business purposes;
• limit our ability to use our cash flow or obtain additional financing for future working capital, capital expenditures, acquisitions or other general business purposes;
• require us to use a substantial portion of our cash flow from operations to make pay the principal of the Notes when they mature and, if required, interest on the Notes;
• limit our flexibility to plan for, or react to, changes in our business and industry;
• place us at a competitive disadvantage compared to our less leveraged competitors; and
• increase our vulnerability to the impact of adverse economic and industry conditions.

If issued, the Notes will be Senti Holdings’ senior, secured indebtedness and are to be guaranteed by us and all our direct and indirect subsidiaries (other than Senti Holdings) pursuant to a guarantee in favor of the holder of the Notes. The Notes will be secured by a first priority lien, subject to certain permitted liens, in all of the current and future assets of Senti Holdings, of ours and of all direct and indirect subsidiaries of Senti Holdings, subject to certain customary exclusions. In certain circumstances, the holder of the Notes may be entitled to foreclose on the loan, and such foreclosure would be expected to result in a material, adverse effect on our business, results of operation, liquidity and prospects.

In addition, the terms of the Notes and the Securities Purchase Agreement limit our ability to raise equity capital. We may experience a material adverse affect on our business to the extent we are unable to access available equity capital due to such limitations.

Servicing our Notes may require a significant amount of cash. We may not have sufficient cash flow from our business to pay such debt, and we may not have the ability to raise the funds necessary to settle conversions of the Convertible Notes in cash or to repurchase the Convertible Notes upon a fundamental change, which could adversely affect our business and results of operations.

The Notes will not bear any interest unless an event of default has occurred. If issued, the Notes will have a maturity date (the “Maturity Date”) on the date that is the first business day immediately following the date that is six months after the closing date of the Initial Notes. On the Maturity Date, if the Notes have not previously been converted or exchanged, Senti Holdings is required to pay an amount in cash equal to 200% of all outstanding principal and accrued and unpaid interest. Under certain circumstances, we may force the conversion or exchange of the Notes into shares of common stock prior to their maturity.

Our ability to make scheduled payments of the principal of, and, if applicable, to pay interest on, any Notes we may issue, depends on our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. Our business is not expected to generate cash flow from operations sufficient to service our indebtedness and make necessary capital expenditures. As a result, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt, or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to repay or refinance the Notes will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Further, the Notes contain several customary events of default. In the case of events of default that relate to bankruptcy, the Company is required to redeem the Notes in cash, and in the case of other events of default, the Holders may require the Company to redeem their Notes in cash. The redemption price is the greater of (i) 200% of the outstanding principal amount of the Notes and (ii) the product of (x) the principal amount being redeemed and (y) the quotient obtained by dividing the greatest closing sale price of the Issuer common stock during the event of default by the lowest exchange price during such period. However, we may not have enough available cash, or be able to obtain sufficient financing, at the time we are required to redeem the Notes.

Exchange of the Notes will dilute the ownership interest of existing stockholders or may otherwise depress the price of our common stock.

Assuming the Notes are issued, the exchange of some or all of the Notes will dilute the ownership interests of stockholders as shares of our common stock are delivered upon such exchange. The Notes will be exchangeable at the option of their holders prior to their scheduled terms. Any sales in the public market of the common stock issuable upon such exchange could materially and adversely affect prevailing market prices of our common stock. In addition, the existence of the Notes may encourage short selling by market participants because the exchange of the

Notes could be used to satisfy short positions, or anticipated exchange of the Notes into shares of our common stock could depress the price of our common stock.

In addition, assuming the Notes are issued, the conversion of some or all of the Notes into shares of Senti Holdings will dilute our ownership interests in Senti Holdings, the holding entity of our operating business Senti Biosciences, Inc. In the event that the maximum amount of Notes are sold under the Securities Purchase Agreement and such Notes are subsequently converted into equity of Senti Holdings, the Note holders would own more than a majority of the equity of Senti Holdings.

Moreover, issuances of our common stock at a price below the conversion/exchange price then in effect would result in full-ratchet anti-dilution adjustments under the terms of the Notes. Such issuances would therefore result in additional dilution to our stockholders.
