Rhea-AI Filing Summary

Bone Biologics Corporation reported no revenue and a net loss of $765,988 for the three months ended March 31, 2026, an improvement from a $1,017,092 loss a year earlier. Research and development spending fell to $141,597 as clinical trial timing shifted, while general and administrative costs rose modestly to $663,457.

Cash was $4,530,040 at March 31, 2026, down from $5,334,322 at year-end, and operating cash outflow was $804,282. Management estimates operating expenditures of $5.4 million over the next twelve months and expects existing cash to fund operations into the fourth quarter of 2026, but the filing states there is “substantial doubt” about the company’s ability to continue as a going concern without additional financing.

Positive

  • None.

Negative

  • Going concern uncertainty: The company discloses “substantial doubt” about its ability to continue as a going concern within one year, with $4,530,040 in cash at March 31, 2026 and estimated operating expenditures of $5.4 million over the next twelve months, implying reliance on additional financing.

Insights

Clinical-stage progress continues, but going concern risk remains elevated.

Bone Biologics is still pre-revenue and focused on its NELL-1/DBM platform and the NB1 bone graft device, with R&D expense of $141,597 in Q1 2026 versus $423,576 a year earlier as trial timing reduced costs.

The company ended the quarter with cash of $4,530,040 and an accumulated deficit of about $88.9 million. Management estimates $5.4 million in operating expenditures over the next twelve months and explicitly notes “substantial doubt” about the ability to continue as a going concern without new capital.

Net loss narrowed to $765,988, helped by lower R&D and higher interest income of $38,801. However, without revenue and with expected cash coverage only into the fourth quarter of 2026, future debt or equity raises, including potential use of the at-the-market facility, will be important for sustaining development of the NB1 clinical program.

going concern financial
"These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued."
A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.
at the market offering financial
"the Company entered into an At The Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC"
An at-the-market offering is a way a company raises cash by selling newly issued shares directly into the open market at prevailing prices, rather than all at once in a single deal. Think of it like turning a faucet on to drip shares into trading at current prices when needed; it gives the company flexibility to raise funds over time but can dilute existing shareholders and potentially affect the stock price, which investors should monitor.
warrant liability financial
"Warrant liability was valued using a Black-Scholes model and reported as a liability at $438 as of March 31, 2026."
Warrant liability is the financial obligation a company records when it grants warrants—special options giving the holder the right to buy company shares at a set price in the future. It matters to investors because changes in this liability can affect a company's reported earnings and overall financial health, similar to how a pending contract can influence a company's future value.
device/drug combination product medical
"NELL-1/DBM will be classified as a device/drug combination product that will require an FDA-approved pre-market approval application"
pre-market approval regulatory
"will require an FDA-approved pre-market approval (“PMA”) application before it can be commercialized in the United States."
Official government authorization required before a regulated product can be legally sold to the public; commonly used for high-risk medical devices and certain drugs where regulators review safety and effectiveness. It matters to investors because obtaining or failing to obtain this clearance determines whether a product can start earning revenue, affects company value and timelines, and often prompts significant stock moves—like needing a building permit before opening a shop.
pilot clinical study medical
"the multicenter, prospective, randomized pilot clinical study of our NB1 bone graft device"
A pilot clinical study is a small, early trial that tests whether a new medical treatment or procedure is feasible, safe and worth studying further, like a prototype test drive before mass production. For investors, pilot results provide the first real-data signals about whether a therapy shows promise, what risks or side effects appear, and whether larger, more expensive trials are likely — information that can meaningfully change a company’s development plan and valuation.

Bone Biologics Corporation

Notes to Unaudited Condensed Consolidated Financial Statements

For the Three Months ended March 31, 2026 and 2025

 

1. The Company

 

Bone Biologics Corporation (the “Company”) was incorporated under the laws of the State of Delaware on October 18, 2007 as AFH Acquisition X, Inc. Pursuant to a merger agreement, dated September 19, 2014, the Company’s wholly-owned subsidiary, Bone Biologics Acquisition Corp., merged with and into Bone Biologics Inc., with Bone Biologics Inc. remaining as the surviving corporation. On September 22, 2014, the Company changed its name to “Bone Biologics Corporation” and Bone Biologics, Inc. became a wholly owned subsidiary of the Company. Bone Biologics, Inc. was incorporated in California on September 9, 2004.

 

The Company is a medical device company that is currently focused on bone regeneration in spinal fusion using the recombinant human protein known as NELL-1. NELL-1 in combination with DBM, demineralized bone matrix, is an osteopromotive recombinant protein that provides target specific control over bone regeneration. The NELL-1 technology platform has been licensed exclusively for worldwide applications to the Company through a technology transfer from the UCLA Technology Development Group on behalf of UC Regents (“UCLA TDG”). UCLA TDG and the Company received guidance from the U.S. Food and Drug Administration (“FDA”) that NELL-1/DBM will be classified as a device/drug combination product that will require an FDA-approved pre-market approval (“PMA”) application before it can be commercialized in the United States.

 

The production and marketing of the Company’s products and its ongoing research and development activities are subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any combination product developed by the Company must undergo rigorous preclinical (animal) and clinical (human) testing and an extensive regulatory approval process implemented by the FDA under the Federal Food, Drug and Cosmetic Act. There can be no assurance that the Company will not encounter problems in clinical trials that will cause the Company or the FDA to delay or suspend clinical trials.

 

The Company’s success will depend in part on its ability to obtain patents and product license rights, maintain trade secrets, and operate without infringing on the proprietary rights of others, both in the United States and other countries. There can be no assurance that patents issued to or licensed by the Company will not be challenged, invalidated, rendered unenforceable, or circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to the Company.

 

The Company is also subject to additional risks and uncertainties arising from changes to the macroeconomic environment and geopolitical events. U.S. and global financial markets have experienced volatility and disruption due to macroeconomic and geopolitical events such as the implementation of tariffs, inflation, the risk of a recession and ongoing conflicts in other countries. In addition, if equity and credit markets deteriorate, it may make any future debt or equity financing more difficult to obtain on favorable terms, and potentially more dilutive to existing stockholders. The Company cannot predict at this time to what extent it and its collaborators, employees, suppliers, contract manufacturers and/or vendors could potentially be negatively impacted by these events.

 

Going Concern and Liquidity

 

The Company has no significant operating history and since inception to March 31, 2026, has incurred accumulated losses of approximately $88.9 million. The Company will continue to incur significant expenses for development activities for their lead product NELL-1/DBM. Operating expenditures for the next twelve months are estimated at $5.4 million. The accompanying consolidated financial statements for the three months ended March 31, 2026 have been prepared assuming the Company will continue as a going concern. As reflected in the accompanying financial statements, the Company incurred a net loss of $0.8 million and used net cash in operating activities of $0.8 million during the three months ended March 31, 2026. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. In addition, our independent registered public accounting firm, in their audit report to the financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, expressed substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

 

F-6

 

 

At March 31, 2026, the Company had cash of $4.5 million. Available cash is expected to fund the Company’s operations into the fourth quarter of 2026.

 

The Company will continue to attempt to raise additional debt and/or equity financing to fund future operations and to provide additional working capital. However, there is no assurance that such financing will be consummated or obtained in sufficient amounts necessary to meet the Company’s needs. If cash resources are insufficient to satisfy the Company’s on-going cash requirements, the Company will be required to scale back or discontinue its product development programs, or obtain funds if available (although there can be no certainties) through strategic alliances that may require the Company to relinquish rights to its technology, or substantially reduce or discontinue its operations entirely. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to the Company. Even if the Company is able to obtain additional financing, it may contain undue restrictions on the Company’s operations, in the case of debt financing, or cause substantial dilution for its stockholders, in the case of equity financing.

 

Reverse Stock Split

 

On June 5, 2025, the Company filed an amendment to its amended and restated certificate of incorporation, as amended, with the Secretary of State of the State of Delaware to effect a 1-for-6 reverse stock split of its outstanding common stock and warrants. The amendment was authorized by the Company’s stockholders on May 30, 2025, and was effective on June 10, 2025.

 

All share and per share amounts have been retro-actively restated as if the reverse stock split occurred at the beginning of the earliest period presented.

 

2. Summary of Significant Accounting Policies

 

Basis of Presentation

 

The interim condensed consolidated financial statements included herein reflect all material adjustments (consisting of normal recurring adjustments and reclassifications and non-recurring adjustments) which, in the opinion of management, are ordinary and necessary for a fair presentation of results for the interim periods. Certain information and footnote disclosures required under the accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). The Company believes that the disclosures are adequate to make the information presented not misleading. The condensed consolidated balance sheet information as of December 31, 2025 was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC on March 2, 2026 (the “2025 Annual Report”). These condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2025 and notes thereto included in the 2025 Annual Report.

 

The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the entire fiscal year ended December 31, 2026 or for any other period.

 

Segment Information

 

The Company operates and reports in one segment, which focuses on bone regeneration in spinal fusion using the recombinant human protein known as NELL-1. The Company’s operating segment is reported in a manner consistent with the internal reporting provided to the Chief Operating Decision Maker (the “CODM”), which is the Company’s Chief Executive Officer and President (the “CEO”).

 

The CODM uses consolidated net income (loss) as the sole measure of segment profit or loss. Significant segment expenses include research and development, salaries, insurance, and stock-based compensation. Operating expenses include all remaining costs necessary to operate our business, which primarily include external professional services and other administrative expenses (see Note 8).

 

F-7

 

 

Use of Estimates

 

The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period.

 

Significant estimates include the assumptions used in the accounting for potential liabilities, the valuation of the warrant liability, the valuation of debt and equity instruments, the valuation of stock options and warrants issued for services, and the realizability of the Company’s deferred tax assets. Actual results could differ from those estimates.

 

Inflation

 

Macroeconomic factors such as inflation, rising interest rates, governmental responses there to and possible recession caused thereby also add significant uncertainty to the Company’s operations and possible effects to the amount and type of financing available to the Company in the future.

 

Cash

 

Cash primarily consists of bank demand deposits maintained by a major financial institution. At March 31, 2026, the Company holds $4.1 million in a flexible CD account at Bank of America. This CD has no set maturity date, and funds can be withdrawn any time without penalty.

 

The Company’s policy is to maintain its cash balances with financial institutions with high credit ratings and in accounts insured by the Federal Deposit Insurance Corporation (the “FDIC”) and/or by the Securities Investor Protection Corporation (the “SIPC”). The Company may periodically have cash balances in financial institutions in excess of the FDIC and SIPC insurance limits of $250,000 and $500,000, respectively. The Company has not experienced any losses to date resulting from this policy.

 

Research and Development Costs

 

Research and development costs include, but are not limited to, payroll and other personnel expenses, consultants, expenses incurred under agreements with contract research and manufacturing organizations and animal clinical investigative sites and the cost to manufacture clinical trial materials. Research and development costs are generally charged to operations ratably over the life of the underlying contracts, unless the achievement of milestones, the completion of contracted work, the termination of an agreement, or other information indicates that a different expensing schedule is more appropriate. However, payments for research and development costs that are contractually defined as non-refundable are charged to operations as incurred.

 

Payments made pursuant to contracts are initially recorded as advances on research and development contract services in the Company’s consolidated balance sheet and are then charged to research and development costs in the Company’s consolidated statement of operations as those contract services are performed. Expenses incurred under contracts in excess of amounts advanced are recorded as research and development contract liabilities in the Company’s consolidated balance sheets, with a corresponding charge to research and development costs in the Company’s consolidated statements of operations. The Company reviews the status of its various clinical trial and research and development contracts on a quarterly basis.

 

Fair Value of Financial Instruments

 

Accounting standards require certain assets and liabilities be reported at fair value in the financial statements and provide a framework for establishing that fair value. The Company defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy is based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last is considered unobservable:

 

Level 1: Quoted prices in active markets for identical assets or liabilities.

 

Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

 

Level 3 assumptions: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities including liabilities resulting from embedded derivatives associated with certain warrants to purchase common stock.

 

F-8

 

 

The fair value of financial instruments measured on a recurring basis was as follows:

  

Description  Total   Level 1   Level 2   Level 3 
   As of March 31, 2026 
Description  Total   Level 1   Level 2   Level 3 
Liabilities:                    
Warrant liability  $438           $438 
Total liabilities at fair value  $438           $438 

 

The following table provides a roll-forward of the warrant liability measured at fair value on a recurring basis using unobservable level 3 inputs for the three month period ended March 31, 2026 as follows:

  

   March 31, 2026 
Warrant liability     
Balance as of beginning of period – December 31, 2025  $703 
Change in fair value   (265)
Balance as of March 31, 2026  $438 

 

The Company believes the carrying amount of certain financial instruments, including cash and accounts payable approximate their values based on their short-term nature and are excluded from the fair value tables above.

 

Stock Based Compensation

 

Accounting Standards Codification (“ASC”) 718, Compensation – Stock Compensation, prescribes accounting and reporting standards for all share-based payment transactions to employees and non-employees. Transactions include incurring liabilities, or issuing or offering to issue shares, options, and other equity instruments such as employee stock ownership plans and stock appreciation rights. Share-based payments to employees, including grants of employee stock options, are recognized as compensation expense in the consolidated financial statements based on their fair values. That expense is recognized over the period during which an employee is required to provide services in exchange for the award, known as the requisite service period (usually the vesting period). Recognition of compensation expense for non-employees is in the same period and manner as if the Company had paid cash for the services.

 

Warrants

 

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all of the criteria for equity classification, the warrants are required to be liability classified and recorded at their initial fair value on the date of issuance and remeasured at fair value at each balance sheet date thereafter. Changes in the estimated fair value of the warrants that are liability classified are recognized as a non-cash gain or loss in the statement of operations at each balance sheet date.

 

F-9

 

 

Net Loss per Common Share

 

Basic loss per share is computed by dividing the loss available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted loss per share is computed similar to basic loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. Diluted loss per common share reflects the potential dilution that could occur if options and warrants were to be exercised or converted or otherwise resulted in the issuance of common stock that then shared in the earnings of the entity.

 

Since the effects of outstanding options and warrants are anti-dilutive for the three months ended March 31, 2026 and 2025, shares of common stock underlying these instruments have been excluded from the computation of loss per common share.

 

The following sets forth the number of shares of common stock underlying outstanding options and warrants as of March 31, 2026 and 2025:

 

   2026   2025 
   March 31, 
   2026   2025 
Warrants   2,753,827    309,037 
Stock options   106,490    45,902 
Anti dilutive securities   2,860,317    354,939 

 

New Accounting Standards

 

In November 2024, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2024-03 “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” This ASU requires public business entities to disclose, for interim and annual reporting periods, additional information about certain income statement expense categories. The requirements are effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Entities are permitted to apply either the prospective or retrospective transition methods. The Company is in the process of evaluating the adoption of this ASU to determine its impact on the Company’s disclosures.

 

In November 2024, the FASB issued ASU 2024-04 “Debt with Conversion and Other Options (Subtopic 470-20)”. This ASU clarifies the requirements related to accounting for the settlement of a debt instrument as an induced conversion. An induced conversion is when a company induces debt holders to convert their debt into equity shares under changed terms and involved additional consideration. The amendments in this ASU are effective for all entities for annual reporting periods beginning January 1, 2026, and interim reporting periods within those annual reporting periods. The adoption of this ASU has not had a material effect on the Company’s financial position, results of operations or cash flows.

 

In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which includes amendments to clarify interim reporting requirements and applicability of Topic 270 and codifies a principle requiring disclosure of material events and changes since the most recent annual reporting period. This guidance is effective for the Company for interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is in the process of evaluating the impact of adoption of this ASU on its Condensed Consolidated Financial Statements.

 

F-10

 

 

The Company’s management has evaluated all other recently issued, but not yet effective, accounting standards and guidance that have been issued or proposed by the FASB or other standards-setting bodies through the filing date of these financial statements and does not believe the future adoption of any such pronouncements will have a material effect on the Company’s financial position and results of operations.

 

3. Research and Development

 

The Company has developed a stand-alone platform technology through significant laboratory and small and large animal research over more than ten years to generate the current applications across broad fields of use, including the completion of two preclinical sheep studies that demonstrated our recombinant NELL-1 (“rhNELL-1”) growth factor effectively promotes bone formation in a phylogenetically advanced spine model.

 

During 2024, the Company announced the treatment of the first subjects in the multicenter, prospective, randomized pilot clinical study of our NB1 bone graft device. NB1 is NELL-1 protein combined with demineralized bone matrix (DBM) to provide rapid, specific and guided control over bone regeneration.

 

The pilot clinical study will evaluate the safety and effectiveness, fusion success, pain, function improvement and adverse events of NB1 in up to 30 adult subjects who undergo transforaminal lumbar interbody fusion to treat degenerative disc disease. To be enrolled in the study, subjects must have DDD at one level from L2-S1 and may also have up to Grade 1 spondylolisthesis or Grade 1 retrolisthesis at the involved level. The study is being conducted in Australia. The study design was previously reviewed and agreed upon by the FDA’s Division of Orthopedic Devices in a Pre-submission to support progression to a pivotal clinical trial in the United States.

 

The Company has entered into various agreements with Contract Manufacturing Organizations (“CMOs”), Contract Research Organizations and other third parties related to our pilot clinical study. For the three-month periods ended March 31, 2026 and 2025, research and development expenses were principally attributable to clinical trials conducted for the Company’s lead product candidate. At March 31, 2026, the estimated remaining commitment under these agreements is approximately $210,419.

 

Research and development costs are summarized below based on the respective geographical regions where such costs are incurred.

4. Warrant Liability

 

In October 2022, the Company completed a public equity offering, which included the issuance of 9,029 warrants to purchase shares of common stock that expire in October 2027. The warrants provide for a Black Scholes value calculation, as defined, in the event of certain fundamental transactions, which includes a floor on volatility utilized in the Black Scholes value calculation at 100% or greater. The Company has determined that this provision introduces leverage to the holders of the warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed option on the Company’s own equity shares. Accordingly, pursuant to ASC 815, the Company has classified the fair value of the warrants as a liability to be re-measured at the end of every reporting period with the change in value reported in the statement of operations.

 

F-11

 

 

The warrant liability was valued at the following dates using a Black-Scholes model with the following assumptions:

 

  

March 31,

2026

  

December 31,

2025

 
Warrant liability:          
Risk-free interest rate   3.74%   3.47%
Expected volatility   98.79%   155.04%
Expected life (in years)   1.53    1.78 
Expected dividend yield   -    - 
           
Fair Value of warrant liability  $438   $703 

 

The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company determines expected volatility based upon the historical volatility of the Company’s common stock. The Company does not believe that the future volatility of its common stock over an option’s expected term is likely to differ significantly from the past. The expected term of the warrants granted are determined based on the duration of time the warrants are expected to be outstanding. The dividend yield on the Company’s warrants is assumed to be zero as the Company has not historically paid dividends.

 

5. Stockholders’ Equity

 

Preferred Stock

 

The Company’s amended and restated certificate of incorporation authorizes the Company to issue a total of 20,000,000 shares of preferred stock. No shares have been issued.

 

Common Stock

 

The Company’s amended and restated certificate of incorporation authorizes the Company to issue a total of 100,000,000 shares of common stock. As of March 31, 2026 and December 31, 2025, the Company had an aggregate of 1,795,260 shares of common stock outstanding.

 

2025 transactions

 

At the Market (ATM) Offering Program

 

In September 2024, the Company entered into an At The Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC (“Wainwright”). Under the ATM Agreement, the Company may, from time to time, in its sole discretion, issue and sell through Wainwright up to $1,143,121 of shares of its common stock. In December 2024, the Company filed a prospectus supplement and increased the aggregate offering that can be sold under the ATM Agreement by $535,000 . In March 2026, the Company filed an additional prospectus supplement and increased the aggregate offering that can be sold under the ATM Agreement to $1,064,000 (the “ATM Facility”).

 

Pursuant to the ATM Agreement, the Company may sell the shares by any method permitted that is deemed an “at the market” offering as defined in Rule 415 under the Securities Act. The Company will pay Wainwright a commission of 3.0% of the gross sales price per share sold under the ATM Agreement.

 

During the three months ended March 31, 2025, the Company sold 52,843 shares of common stock through the ATM Facility for net proceeds of $347,549, after deducting $13,029 in offering costs. The Company did not sell any shares of common stock through the ATM Facility during the three months ended March 31, 2026.

7. Stock-based Compensation

 

2015 Equity Incentive Plan

 

The Company has 5,104,915 shares of common stock authorized and reserved for issuance under its 2015 Equity Incentive Plan, as amended, for option awards. This reserve may be increased by the Board of Directors each year by up to the number of shares of stock equal to 5% of the number of shares of stock issued and outstanding on the immediately preceding December 31. Appropriate adjustments will be made in the number of authorized shares and other numerical limits in the Company’s 2015 Equity Incentive Plan and in outstanding awards to prevent dilution or enlargement of participants’ rights in the event of a stock split or other change in the Company’s capital structure. Shares subject to awards granted under the 2015 Equity Incentive Plan which expire, are repurchased or are cancelled or forfeited will again become available for issuance under the 2015 Equity Incentive Plan. The shares available will not be reduced by awards settled in cash. Shares withheld to satisfy tax withholding obligations will not again become available for grant. The gross number of shares issued upon the exercise of stock appreciation rights or options exercised by means of a net exercise or by tender of previously owned shares will be deducted from the shares available under the 2015 Equity Incentive Plan.

 

Awards may be granted under the 2015 Equity Incentive Plan to the Company’s employees, including officers, director or consultants, and its present or future affiliated entities. While the Company may grant incentive stock options only to employees, it may grant non-statutory stock options, stock appreciation rights, restricted stock purchase rights or bonuses, restricted stock units, performance shares, performance units and cash-based awards or other stock based awards to any eligible participant.

 

The 2015 Equity Incentive Plan is administered by the Company’s compensation committee. Subject to the provisions of the 2015 Equity Incentive Plan, the compensation committee determines, in its discretion, the persons to whom, and the times at which, awards are granted, as well as the size, terms and conditions of each award. All awards are evidenced by a written agreement between the Company and the holder of the award. The compensation committee has the authority to construe and interpret the terms of the 2015 Equity Incentive Plan and awards granted under the 2015 Equity Incentive Plan.

Total outstanding options at March 31, 2026        106,490    

 

Based on a fair value of $1.10 per share on March 31, 2026, there were no exercisable but unexercised in-the-money common stock warrants on that date.

 

During the three months ended March 31, 2026, options exercisable into 6,290 shares of common stock expired. Vesting of options differs based on the terms of each option. During the three months ended March 31, 2026 and 2025, the Company had stock-based compensation expense of $23,505 and $50,605, respectively, related to the vesting of stock options granted to the Company’s employees and directors included in our reported net loss. In addition, during the three months ended March 31, 2026 and 2025, options exercisable into 25,003 and 13,529, shares of common stock respectively, were issued to employees in settlement of previously accrued bonuses of $34,854 and $46,183, respectively.

 

The Company utilized the Black-Scholes option-pricing model. The assumptions used for the three months ended March 31, 2026 are as follows:

 

      

   March 31, 2026 
Risk free interest rate   3.74%
Expected Volatility   142.68%
Expected life (in years)   5 
Expected dividend yield   0%

 

The expected volatility is a measure of the amount by which the Company stock price is expected to fluctuate during the expected term of options granted. The Company determines the expected volatility based upon the historical volatility of our common stock since listing on the Nasdaq Capital Market. The Company does not believe that the future volatility of its common stock over an option’s expected term is likely to differ significantly from the past. The risk-free interest rate used in the calculations is based on the implied yield available on U.S. Treasury issues with an equivalent term approximating the expected life of the options as calculated using the simplified method. The expected life of the options used was based on the contractual life of the option granted. Stock-based compensation is a non-cash expense because the Company settles these obligations by issuing shares of its common stock from its authorized shares instead of settling such obligations with cash payments.

9. Commitments and Contingencies

 

UCLA TDG Exclusive License Agreement

 

Effective April 9, 2019, the Company entered into an Amended and Restated Exclusive License Agreement, as so amended (the “Amended License Agreement”), with the UCLA TDG. The Amended License Agreement amends and restates the Amended and Restated Exclusive License Agreement, dated as of June 19, 2017 (the “2017 Agreement”). The 2017 Agreement amended and restated the Exclusive License Agreement, effective March 15, 2006, between the Company and UCLA TDG, as amended by ten amendments. Under the terms of the Amended License Agreement, the Regents have continued to grant the Company exclusive rights to develop and commercialize NELL-1 (the “Licensed Product”) for spinal fusion by local administration, osteoporosis and trauma applications. The Licensed Product is a recombinant human protein growth factor that is essential for normal bone development.

 

The Company has agreed to pay an annual maintenance fee to UCLA TDG of $10,000 as well as pay certain royalties to UCLA TDG under the Amended License Agreement at the rate of 3.0% of net sales of licensed products or licensed methods. The Company must pay the royalties to UCLA TDG on a quarterly basis. Upon a first commercial sale, the Company also must pay a minimum annual royalty between $50,000 and $250,000, depending on the calendar year which is after the first commercial sale. If the Company is required to pay a third party any royalties as a result of it making use of UCLA TDG patents, then it may reduce the royalty owed to UCLA TDG by 0.333% for every percentage point paid to a third party. If the Company grants sublicense rights to a third party to use the UCLA TDG patent, then it will pay UCLA TDG 10% to 20% of the sublicensing income it receives from such sublicense.

 

F-16

 

 

The Company is obligated to make the following milestone payments to UCLA TDG for each Licensed Product or Licensed Method:

 

  $100,000 upon enrollment of the first subject in a Feasibility Study;
     
  $250,000 upon enrollment of the first subject in a Pivotal Study:
     
  $500,000 upon Pre-Market Approval of a Licensed Product or Licensed Method; and
     
  $1,000,000 upon the First Commercial Sale of a Licensed Product or Licensed Method.

 

The Company is also obligated pay to UCLA TDG a fee (the “Diligence Fee”) of $8,000,000 upon the sale of any Licensed Product (the “Triggering Sale Date”) in accordance with the payment schedule below:

 

  Due upon cumulative Net Sales equaling $50,000,000 following the Triggering Sale Date - $2,000,000;
     
  Due upon cumulative Net Sales equaling $100,000,000 following the Triggering Sale Date - $2,000,000; and
     
  Due upon cumulative Net Sales equaling $200,000,000 following the Triggering Sale Date - $4,000,000.

 

The Company’s obligation to pay the Diligence Fee will survive termination or expiration of the Amended License and it is prohibited from assigning, selling, or otherwise transferring any of its assets related to any Licensed Product unless its Diligence Fee obligation is assigned, sold, or transferred along with such assets, or unless it pays UCLA TDG the Diligence Fee within ten (10) days of such assignment, sale or other transfer of such rights to any Licensed Product.

 

The Company is also obligated to pay UCLA TDG a cash milestone payment within thirty (30) days of a Liquidity Event (including a Change of Control Transaction and a payment election by UCLA TDG exercisable after December 22, 2016) such payment to equal the greater of (i) $500,000; or (ii) 2% of all proceeds in connection with a Change of Control Transaction.

 

During 2024, the first subjects were treated in the multicenter, prospective, randomized pilot clinical study of the Company’s NB1 bone graft device, triggering the payment of the initial $100,000 Feasibility Study milestone.

 

The Company is obligated to diligently proceed with developing and commercializing licensed products under UCLA TDG patents set forth in the Amended License Agreement. UCLA TDG has the right to either terminate the license or reduce the license to a non-exclusive license if it does not meet certain diligence milestone deadlines set forth in the Amended License Agreement.

 

The Company must reimburse or pre-pay UCLA TDG for patent prosecution and maintenance costs incurred during the term of the Amended License Agreement. The Company has the right to bring infringement actions against third-party infringers of the Amended License Agreement, UCLA TDG may join voluntarily, at its own expense, or, at the Company’s expense, be joined involuntarily to the action. The Company is required to indemnify UCLA TDG against any third-party claims arising out of its exercise of the rights under the Amended License Agreement or any sublicense.

 

Payments to UCLA TDG under the Amended License Agreement for the three months ended March 31, 2026 and 2025 were $10,237 and $10,000, respectively.

 

Contingencies

 

The Company is subject to claims and assessments from time to time in the ordinary course of business. The Company’s management does not believe that any such matters, individually or in the aggregate, will have a material adverse effect on the Company’s business, financial condition, results of operations or cash flows.

 

10. Subsequent Events

 

The Company has evaluated subsequent events through May 14, 2026, the date which the consolidated financial statements were available to be issued. There were no additional subsequent events noted that would require adjustment to or disclosure in these consolidated financial statements.

Item 2. Management’s Discussion and Analysis.

 

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the condensed consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q and audited consolidated financial statements for the years ended December 31, 2025 and 2024 and the related notes included in our Annual Report on Form 10-K filed for the fiscal year ended December 31, 2025, with the SEC on March 2, 2026. This discussion contains forward-looking statements reflecting our current expectations that involve risks and uncertainties. See “Note On Forward-Looking Statements” for a discussion of the uncertainties, risks and assumptions associated with these statements. Actual results and the timing of events could differ materially from those discussed in our forward-looking statements as a result of many factors.

 

Company Overview

 

We are a medical device company that is currently focused on bone regeneration in spinal fusion using the recombinant human protein known as NELL-1. NELL-1 in combination with DBM, demineralized bone matrix, is an osteopromotive recombinant protein that provides target specific control over bone regeneration. The NELL-1 technology platform has been licensed exclusively for worldwide applications to us through a technology transfer from UCLA TDG. UCLA TDG and the Company received guidance from the FDA that NELL-1/DBM will be classified as a device/drug combination product that will require an FDA-approved PMA before it can be commercialized in the United States.

 

We were founded by University of California professors in collaboration with an Osaka University professor and a University of Southern California surgeon in 2004 as a privately-held company with proprietary, patented platform technology. Our platform technology has been validated in sheep and non-human primate models to facilitate bone growth. We believe our platform technology has application in delivering improved outcomes in the surgical specialties of spinal, orthopedic, general orthopedic, plastic reconstruction, neurosurgery, interventional radiology, and sports medicine. Lead product development and clinical studies are targeted on spinal fusion surgery, one of the larger segments in the orthopedic market.

 

We are a clinical-stage entity. The production and marketing of our products and ongoing research and development activities are subject to extensive regulation by numerous governmental authorities in the United States. Prior to marketing in the United States, any combination product developed by us must undergo rigorous preclinical (animal) and clinical (human) testing and an extensive regulatory approval process implemented by the FDA under the Federal Food, Drug, and Cosmetic Act. There can be no assurance that we will not encounter problems in clinical trials that will cause us or the FDA to delay or suspend clinical trials.

 

Our success will depend in part on our ability to obtain and retain patents and product license rights, maintain trade secrets, and operate without infringing on the proprietary rights of others, both in the United States and other countries. In the second quarter of 2025, we submitted a patent application with the United States Patent and Trademark Office (“USPTO”) regarding proprietary compositions of rhNELL-1 polypeptide for treating bone conditions There can be no assurance that the USPTO will approve our patent application or that the patents issued to or licensed by us will not be challenged, invalidated, rendered unenforceable, or circumvented, or that the rights granted thereunder will provide proprietary protection or competitive advantages to us.

 

During 2024, we announced the treatment of the first subjects in the multicenter, prospective, randomized pilot clinical study of our NB1 bone graft device. NB1 is NELL-1 protein combined with demineralized bone matrix (DBM) to provide rapid, specific and guided control over bone regeneration.

 

The pilot clinical study will evaluate the safety and effectiveness, fusion success, pain, function improvement and adverse events of NB1 in up to 30 adult subjects who undergo transforaminal lumbar interbody fusion to treat degenerative disc disease (DDD). To be enrolled in the study, subjects must have DDD at one level from L2-S1 and may also have up to Grade 1 spondylolisthesis or Grade 1 retrolisthesis at the involved level. The study is being conducted in Australia. The study design was previously reviewed and agreed upon by the FDA’s Division of Orthopedic Devices in a Pre-submission to support progression to a pivotal clinical trial in the United States.

ATM Offering

 

In September 2024, we entered into ATM Agreement with Wainwright. Under the ATM Agreement, we may, from time to time, in our sole discretion, issue and sell through Wainwright up to $1,143,121 of shares of its common stock. In December 2024, we filed a prospectus supplement and increased the aggregate offering that can be sold under the ATM Agreement by $535,000. In March 2026, we filed an additional prospectus supplement and increased the aggregate offering that can be sold under the ATM Facility to $1,064,000.

 

Pursuant to the ATM Agreement, we may sell the shares by any method permitted that is deemed an “at the market” offering as defined in Rule 415 under the Securities Act. We will pay Wainwright a commission of 3.0% of the gross sales price per share sold under the ATM Agreement.

 

During the three months ended March 31, 2025, we sold 52,843 shares of common stock through the ATM Facility for net proceeds of $347,549, after deducting $13,029 in offering costs. We did not sell any shares of common stock through the ATM Facility during the three months ended March 31, 2026.

 

Results of Operations

 

Since our inception, we devoted substantially all of our efforts and funding to the development of the NELL-1 protein and raising capital. We have not yet generated revenues from our planned operations.

Research and Development

 

Our research and development expenditures decreased from $423,576 for the three months ended March 31, 2025, to $141,597 for the same period in 2026, marking a decrease of $281,979. The decrease in costs can be attributed to timing of our clinical trial. We anticipate continued substantial investment in development activities for NELL-1 as we prepare for our pivotal clinical study in the future.

 

General and Administrative

 

Our general and administrative expenses increased by $48,547, rising from $614,910 for the three months ended March 31, 2025, to $663,457 for the same period in 2026.

 

Change in fair value of warrant liability

 

In October 2022, we completed a public equity offering, which included the issuance of 9,029 warrants to purchase shares of common stock that expire in October 2027. The warrants provide for a Black Scholes value calculation in the event of certain fundamental transactions, which includes a floor on volatility utilized in the value calculation at 100% or greater. We have determined that this provision introduces leverage to the holders of the warrants that could result in a value that would be greater than the settlement amount of a fixed-for-fixed option on the Company’s own equity shares. Accordingly, pursuant to ASC 815, we have classified the fair value of the warrants as a liability to be re-measured at the end of every reporting period with the change in value reported in the statement of operations.

 

The change in fair value of warrant liability represents the re-measurement of the outstanding warrants at March 31, 2026.

Liquidity and Capital Resources

 

Going Concern and Liquidity

 

We have no significant operating history and since inception to March 31, 2026 have incurred accumulated losses of approximately $88.9 million. We will continue to incur significant expenses for development activities for our lead product NELL-1/DBM. Operating expenditures for the next twelve months are estimated at $5.4 million. The accompanying consolidated financial statements for the three months ended March 31, 2026 have been prepared assuming we will continue as a going concern. As reflected in the financial statements, we incurred a net loss of $0.8 million and used net cash in operating activities of $0.8 million during the three months ended March 31, 2026. These factors raise substantial doubt about our ability to continue as a going concern within a reasonable period of time, which is considered to be one year after the date that the financial statements are issued. In addition, our independent registered public accounting firm, in their report on the Company’s audited financial statements for the year ended December 31, 2025, expressed substantial doubt about our ability to continue as a going concern. The consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern.

 

We will continue to attempt to raise additional debt and/or equity financing to fund future operations and to provide additional working capital. However, there is no assurance that such financing will be consummated or obtained in sufficient amounts necessary to meet our needs. If cash resources are insufficient to satisfy our on-going cash requirements, we will be required to scale back or discontinue our product development programs, or obtain funds if available (although there can be no certainties) through strategic alliances that may require us to relinquish rights to our technology or substantially reduce or discontinue our operations entirely. No assurance can be given that any future financing will be available or, if available, that it will be on terms that are satisfactory to us. Even if we are able to obtain additional financing, it may contain undue restrictions on our operations, in the case of debt financing, or cause substantial dilution for our stockholders, in the case of equity financing.

 

At March 31, 2026 and December 31, 2025, we had cash of $4,530,040 and $5,334,322, respectively.

 

We expect our available cash to fund our operations into the fourth quarter of 2026.

Bone Biologics reported a Q1 2026 net loss of $765,988, improving from a $1,017,092 loss a year earlier. The company had no revenue, lower research and development spending, slightly higher general and administrative costs, and remains a clinical-stage, pre-revenue business.

What is Bone Biologics’ cash position and runway as of March 31, 2026?

The company held $4,530,040 in cash at March 31, 2026, down from $5,334,322 at December 31, 2025. Management expects this to fund operations into the fourth quarter of 2026, assuming estimated operating expenditures of $5.4 million over the next twelve months.

Does Bone Biologics’ Q1 2026 filing mention going concern risks?

Yes. The filing states that recurring losses, cash usage and planned spending “raise substantial doubt” about the company’s ability to continue as a going concern. Its independent auditor also expressed substantial doubt in the December 31, 2025 audit report referenced in the quarterly disclosure.

What were Bone Biologics’ research and development expenses in Q1 2026?

Research and development expense was $141,597 for the three months ended March 31, 2026, down from $423,576 in the prior-year quarter. Management attributes the decrease primarily to the timing of clinical trial activities for the company’s NELL-1/DBM-based NB1 bone graft device.

Weighted average shares outstanding were 1,795,260 for Q1 2026, with basic and diluted loss per share of $(0.43). As of May 14, 2026, the filing reports 1,795,260 shares of common stock outstanding, reflecting no change in share count during the quarter.

No. The company reported revenues of $0 for the three months ended March 31, 2026 and March 31, 2025. It remains a clinical-stage medical device company, investing in development and trials for its NELL-1/DBM-based NB1 bone graft device without commercial sales yet.
