75,000 Placement Agent Warrants to Purchase 75,000 Shares of Common Stock

75,000 Shares of Common Stock Underlying the Placement Agent Warrants

We are offering 793,950 shares of common stock, par value $0.001 per share (“common stock”), together with Series D warrants to purchase 1,250,000 shares of common stock (the “Series D Warrants”) and Series E warrants to purchase 1,250,000 shares of common stock (the “Series E Warrants”), which we refer to collectively as the “warrants,” at a combined public offering price of $4.00 per share and accompanying warrants. Each share of our common stock is being sold together with one Series D Warrant to purchase one share of common stock and one Series E Warrant to purchase one share of common stock. The Series D Warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series D Warrants will expire on the five-year anniversary of the date of issuance. The Series E Warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series E Warrants will expire on the 18-month anniversary of the date of issuance.

This prospectus also relates to the offering of the shares of common stock issuable upon exercise of the warrants.

We are also offering to those investors whose purchase of shares of our common stock in this offering would result in such investor, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the investor, 9.99%) of our outstanding common stock following the consummation of this offering, the opportunity to purchase, in lieu of the common stock that would otherwise result in the investor’s beneficial ownership exceeding 4.99% (or, at the election of the investor, 9.99%), 456,250 pre-funded warrants each to purchase one share of our common stock at an exercise price of $0.001, which we refer to as the “pre-funded warrants.” Each pre-funded warrant will be exercisable upon issuance and may be exercised at any time until all of the pre-funded warrants are exercised in full. Each pre-funded warrant is being sold together with one Series D Warrant to purchase one share of common stock and one Series E Warrant to purchase one share of common stock. The public offering price for each pre-funded warrant and the accompanying warrants is equal to the price per share of common stock and the accompanying warrants being sold to the public in this offering, minus $0.001. This prospectus also relates to the offering of the shares of common stock issuable upon exercise of the pre-funded warrants.

For each pre-funded warrant we sell, the number of shares of common stock we sell in this offering will be decreased on a one-for-one basis. The shares of common stock and/or pre-funded warrants and the accompanying warrants can only be purchased together in this offering but will be issued separately and will be immediately separable upon issuance.

This offering will terminate on July 24, 2025 unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or pre-funded warrant) and accompanying warrants will be fixed for the duration of this offering.

We have engaged H.C. Wainwright & Co., LLC, the placement agent, to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number or dollar amount of securities. We have agreed to pay to the placement agent the placement agent fees set forth in the table below, which assumes that we sell all of the securities offered by this prospectus. Since we will deliver the securities to be issued in this offering upon our receipt of investor funds, there is no arrangement for funds to be received in escrow, trust or similar arrangement. There is no minimum offering requirement as a condition of closing of this offering. Because there is no minimum offering amount required as a condition to closing this offering, we may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue our business goals described in this prospectus. In addition, because there is no escrow account and no minimum offering amount, investors could be in a position where they have invested in our company, but we are unable to fulfill all of our contemplated objectives due to a lack of interest in this offering. Further, any proceeds from the sale of securities offered by us will be available for our immediate use, despite uncertainty about whether we would be able to use such funds to effectively implement our business plan. See “Risk Factors” beginning on page 10 of this prospectus for more information. We will bear all costs associated with the offering. See “Plan of Distribution” on page 21 of this prospectus for more information regarding these arrangements.

Our common stock is listed on Nasdaq under the symbol “BBLG.” The last reported sale price of our common stock on Nasdaq on June 26, 2025 was $4.16. There is no established trading market for the pre-funded warrants or the warrants and we do not expect an active market to develop. In addition, we do not intend to list the pre-funded warrants or the warrants on any national securities exchange or other trading market. Without an active trading market, the liquidity of these securities will be limited.

On June 10, 2025, we effected a reverse stock split of our common stock at a ratio of 1-for-6. Unless otherwise noted, the share and per share information in this prospectus reflects the effect of the reverse stock split. However, our Annual Report on Form 10-K for the year ended December 31, 2024, filed on February 26, 2025, and all other documents incorporated by reference into this prospectus that were filed prior to June 10, 2025, do not give effect to reverse stock split.

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 demineralized bone matrix (“DBM”) 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 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.

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. There can be no assurance that 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 patients in the multicenter, prospective, randomized pilot clinical study of our NB1 bone graft device. NB1 is NELL-1 protein combined with 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.

Product Candidates

We have developed a stand-alone platform technology through significant laboratory and small and large animal research over more than 10 years to generate the current applications across broad fields of use. The platform technology is our recombinant human protein, known as NELL-1, a proprietary skeletal-specific growth factor that is a bone void filler. NELL-1 provides regulation over skeletal tissue formation and stem cell differentiation during bone regeneration. We obtained the platform technology pursuant to an exclusive license agreement with UCLA TDG which grants us exclusive rights to develop and commercialize NELL-1 for spinal fusion by local administration, osteoporosis and trauma applications. A major challenge associated with orthopedic surgery is effective bone regeneration, including challenges related to rapid, uncontrolled bone growth that can cause unsound structure; less dense bone formation; unwanted bone formation, and cysts, swelling; and intense inflammatory response to current bone regeneration compounds. We believe NELL-1 will address these unmet clinical challenges for effective bone regeneration, especially in hard healers.

We are currently focused on bone regeneration in lumbar spinal fusion using NELL-1 in combination with DBM, a demineralized bone matrix from MTF Biologics (“MTF”). The combination NELL-1/DBM medical device is an osteopromotive recombinant protein that provides target specific control over bone regeneration. We have successfully surpassed four critical milestones:

	●	Demonstrated a successful small laboratory scale pilot run for the manufacturing of the recombinant NELL-1 protein in Chinese hamster ovary cells;

	●	Validated protein dosing and efficacy in established large animal (sheep) model pilot studies;

	●	Completed pivotal animal study; and

	●	Initiated a first-in-human pilot clinical study in Australia.

Our lead product candidate is expected to be purified NELL-1 mixed with 510(k)-cleared DBM Demineralized Bone Putty recommended for use in conjunction with applicable hardware consistent with the indication. The NELL-1/DBM Fusion Device, NB1, will be comprised of a single dose vial of NELL-1 recombinant protein freeze dried onto DBM. A vial of NELL-1/DBM will be sold in a convenience kit with a diluent and a syringe of 510(k)-cleared demineralized bone (“DBM Putty”) produced by MTF. A delivery device will allow the surgeon to mix the reconstituted NELL-1 with the appropriate quantity of DBM Putty just prior to implantation. Use of NB1 will not require changes to the orthobiologic preparation or implantation protocol.

The NELL-1/DBM Fusion Device, NB1, is intended for use in lumbar spinal fusion and may have a variety of other spine and orthopedic applications. While the product is initially targeted at the lumbar spine fusion market, in keeping with our exclusive license agreement, we believe NELL-1’s novel set of characteristics, target-specific mechanism of action, efficacy, safety and affordability position the product for application in a variety of procedures including:

	Spine Implants. The global bone graft substitute market presents a $3 billion opportunity per Fortune Business Insights. While use of the patient’s own bone, also referred to as autograft, to enhance fusion of vertebral segments is currently the optimal procedure for this type of treatment, complications associated with autograft bone including pain, increased surgical time and infection limit its use.
	Non-Union Trauma Cases. While the majority of fractures heal without the need for osteosynthetic products, bone substitutes are used in complicated breaks where the bone does not mend naturally. Management believes that NELL-1 technology will perform as well as other growth factors, addressing this $8 billion global market opportunity per Fortune Business Insights.

	Osteoporosis. The global osteoporosis market presents an $11.2 billion market opportunity per Evercore analyst reports. Finding a solution to counter a decrease in bone mass and density seen in women most frequently after menopause or a similar effect on astronauts in microgravity environments for an extended period is a major medical challenge. The systemic use of NELL-1 to stimulate bone regeneration throughout the body thereby increasing bone density could have a very significant impact on the treatment of osteoporosis.

UCLA’s initial research was funded with approximately $18 million in resources from UCLA TDG and government grants. Since licensing the exclusive worldwide intellectual property rights from UCLA TDG, we have continued development with funding through capital raises. Our research and development expenses for the years ended December 31, 2024 and 2023 were $2,130,385 and $6,907,824, respectively.

NELL-1’s powerful specific bone forming properties are derived from the ability of NELL-1 to only target cells that exhibit an activated “master switch” to develop into bone. NELL-1 is a function-specific recombinant human protein that has been proven in laboratory bench models to recapitulate normal human growth and development to provide control over bone regeneration.

We have completed two preclinical sheep studies that demonstrated our recombinant NELL-1 (“rhNELL-1”) growth factor effectively promotes bone formation in a phylogenetically advanced spine model. In addition, rhNELL-1 was shown to be well tolerated and there were no findings of inflammation. Our pivotal sheep study evaluated the effect of rhNELL-1 combined with DBM on lumbar interbody arthrodesis in an adult ovine model and demonstrated a 37.5% increased frequency of fusion at 26 weeks compared with the control.

We began subject enrollment in 2024 in our first-in-human pilot clinical study to evaluate the safety and effectiveness of NB1 in adult subjects with spinal degenerative disc disease at one level from L2-S1, who may also have up to Grade 1 spondylolisthesis or Grade 1 retrolisthesis at the involved level, and are undergoing transforaminal lumbar interbody fusion. The multi-center, prospective, randomized study is being conducted in Australia and will enroll up to 30 patients. The primary end-point is fusion success at 12 months and change from baseline in the Oswestry Disability Index pain score. We anticipate completing the trial 12 months after enrolling the 30^th patient. We intend to use the pilot clinical trial data from the Australia study to enable a future, larger U.S. pivotal clinical study, prior to submission of a PMA to the FDA.

Our Business Strategy

Our business plan is to develop our target-specific growth factor for bone regeneration, based on preclinical and clinical data demonstrating increases in the quantity and quality of bone, and a strong safety profile. Our initial focus on lumbar spinal fusion entails advancing our target-specific growth factor through clinical studies to achieve FDA approval with comparable efficacy and safety to the gold standard for spine fusion (autografts). Continued capital funding is critical to facilitate the development of our Nell-1 technology through the clinical regulatory path.

Intellectual Property Risks

Our patent portfolio currently consists of six patents which expire between 2026 and 2033. We intend to expand our portfolio through composition of matter, methods of use and methods of production patent applications, as the opportunity arises through the development of our platform technology. We plan to submit a patent application with the United States Patent and Trademark Office (“USPTO”) by the end of the second quarter of 2025 regarding proprietary compositions of rhNELL-1 polypeptide for treating bone conditions. Our success will depend in part on our 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 the USPTO will approve our patent application or 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. The patent positions of medical device companies are uncertain and involve complex legal and factual questions. We may incur significant expenses in protecting our intellectual property and defending or assessing claims with respect to intellectual property owned by others. See “Risk Factors” on page 10 and other information included or incorporated by reference in this prospectus for a discussion of intellectual property risks to consider carefully before deciding to invest in our securities.

Our Management Team

We have two full-time employees. Jeffrey Frelick has served as our President and Chief Executive Officer since June 2019 and brings more than 35 years of leadership, operational, and investment experience in the life science industry. Deina Walsh has served as our Chief Financial Officer since November 2014.

Mr. Frelick previously served as our Chief Operating Officer from 2015 to June 2019. Prior to Bone Biologics, Mr. Frelick spent 15 years on Wall Street as a sell-side analyst following the med-tech industry at investment banks Canaccord Genuity, ThinkEquity and Lazard.

Areas of specialty include mergers, acquisitions, reverse mergers, consolidations, complex equity structures, foreign currency translations and revenue recognition complexities. Ms. Walsh has an Associates of Science Degree in Business Administration from Monroe Community College and a Bachelor of Science Degree in Accounting from the State University of New York at Brockport.

We have relied and plan on continuing to rely on independent organizations, advisors and consultants to perform certain services for us, including handling substantially all aspects of regulatory approval, clinical management, manufacturing, marketing, and sales. Such services may not always be available to us on a timely basis or at costs that we can afford. We also have engaged and plan to continue to engage regulatory consultants to advise us on our dealings with the FDA and other foreign regulatory authorities and have been and will be required to retain additional consultants and employees.

Our future performance will depend in part on our ability to successfully integrate newly hired officers into our management team, engage and retain consultants, and to develop an effective working relationship with our management and consultants. Losing key personnel or failing to recruit necessary additional personnel would impede our ability to attain our development objectives. Losing key personnel or failing to recruit necessary additional personnel would impede our ability to attain our development objectives.

Recent Developments

Nasdaq Compliance

On April 7, 2025, we received a letter from the Listing Qualifications Staff (the “Staff”) of Nasdaq indicating that, based on the closing bid price of our common stock for 30 consecutive business days, we no longer meet Nasdaq Listing Rule 5550(a)(2), which requires listed companies to maintain a minimum bid price of at least $1 per share (the “Bid Price Rule”). As discussed below, we completed a 1-for-6 reverse stock split on June 10, 2025, and as of the close of business on June 24, 2025, we believe we have regained compliance with the Bid Price Rule because we have maintained a minimum bid price of at least $1 per share for 10 consecutive business days. We expect to receive a letter from the Staff of Nasdaq indicating that we have regained compliance with the Bid Price Rule.

On May 30, 2025, we received the approval of the requisite number of holders of the shares of our common stock to amend our Amended and Restated Certificate of Incorporation, as amended (“Certificate of Incorporation”), to effect a reverse split of the shares of our common stock at a ratio of 1-for-2.5 to 1-for-10 (or any number in between), with the exact ratio to be set within such range in the discretion of our Board of Directors without further approval or authorization of our stockholders. On June 5, 2025, we filed a Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware to effect a 1-for-6 reverse stock split of our outstanding common stock. The reverse stock split became effective on June 10, 2025. The conversion or exercise prices of our issued and outstanding stock options and warrants were adjusted accordingly in connection with the reverse stock split.

Going Concern

We have a history of operating losses since inception and expect to incur additional near-term losses. As discussed further in “Management’s Discussion and Analysis - Liquidity and Capital Resources,” included in our Form 10-K for the year ended December 31, 2024, which is incorporated herein by reference, our independent registered public accounting firm, in its audit report to the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024, expressed substantial doubt about our ability to continue as a going concern. Our consolidated financial statements do not include any adjustments that may result from the outcome of this uncertainty. Following this offering, we will need to raise additional capital to fund our operations and continue to support our planned development and commercialization activities. If we cannot secure the financing needed to continue as a viable business, our stockholders may lose some or all of their investment in us.

Corporate Information

We were 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, by and among the Company, its wholly-owned subsidiary, Bone Biologics Acquisition Corp., a Delaware corporation (“Merger Sub”), and Bone Biologics, Inc., Merger Sub merged with and into Bone Biologics Inc., with Bone Biologics Inc. remaining as the surviving corporation in the merger. Upon the consummation of the merger, the separate existence of Merger Sub ceased. On September 22, 2014, the Company officially changed its name to “Bone Biologics Corporation” to more accurately reflect the nature of its business and Bone Biologics, Inc. became a wholly owned subsidiary of the Company. Bone Biologics, Inc. was incorporated in California on September 9, 2004.

Our principal executive offices are located at 2 Burlington Woods Drive, Suite 100, Burlington MA 01803 and our telephone number is (781) 552-4452. Our website address is www.bonebiologics.com.

THE OFFERING

The following summary contains basic information about this offering. The summary is not intended to be complete. You should read the full text and more specific details contained elsewhere in this prospectus.

Common Stock Offered		793,750 shares.

Pre-Funded Warrants Offered		We are also offering to those investors whose purchase of shares of our common stock in this offering would result in such investor, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the investor, 9.99%) of our outstanding common stock following the consummation of this offering, the opportunity to purchase, in lieu of the common stock that would otherwise result in the investor’s beneficial ownership exceeding 4.99% (or, at the election of the investor, 9.99%), 456,250 pre-funded warrants each to purchase one share of our common stock at an exercise price of $0.001, which we refer to as the “pre-funded warrants.” Each pre-funded warrant will be exercisable upon issuance and may be exercised at any time until all of the pre-funded warrants are exercised in full. Each pre-funded warrant is being sold together with one Series D Warrant to purchase one share of common stock and one Series E Warrant to purchase one share of common stock. The public offering price for each pre-funded warrant and the accompanying warrants is equal to the price per share of common stock and the accompanying warrants being sold to the public in this offering, minus $0.001. For each pre-funded warrant we sell, the number of shares of common stock we sell will be decreased on a one-for-one basis. This prospectus also relates to the offering of the shares of common stock issuable upon exercise of the pre-funded warrants. See “Description of Securities – Pre-Funded Warrants” for additional information.

Warrants Offered		Each share of common stock or pre-funded warrant is being offered together with one Series D Warrant to purchase one share of common stock and one Series E Warrant to purchase one share of common stock. The Series D Warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series D Warrants will expire on the five-year anniversary of the date of issuance. The Series E Warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series E Warrants will expire on the 18-month anniversary of the date of issuance. Each holder of warrants will be prohibited from exercising its warrant for shares of our common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of our common stock then issued and outstanding. However, any holder may increase such percentage to any other percentage not in excess of 9.99%. This offering also relates to the offering of the shares of common stock issuable upon the exercise of the warrants. For more information regarding the warrants, you should carefully read the section titled “Description of Securities — Warrants” in this prospectus.

Placement Agent Warrants		We have agreed to issue to the placement agent or its designees warrants, or the placement agent warrants, to purchase up to 6.0% of the shares of common stock sold in this offering (including the shares of common stock issuable upon the exercise of the pre-funded warrants), at an exercise price of $5.00 per share, which represents 125% of the public offering price per share and accompanying warrants. For a description of the compensation to be received by the placement agent, see “Plan of Distribution” for more information.

Common Stock Outstanding Prior to This Offering		545,260 shares.

Common Stock to be Outstanding After this Offering		1,795,260 shares (assuming full exercise of the pre-funded warrants and no exercise of the warrants offered hereby).

Use of Proceeds		We estimate that the net proceeds of this offering assuming no exercise of the warrants, after deducting placement agent fees and estimated offering expenses, will be approximately $4.3 million, assuming full exercise of the pre-funded warrants and assuming no exercise of the warrants. We intend to use all of the net proceeds we receive from this offering to fund clinical trials, maintain and extend our patent portfolio, and for working capital and other general corporate purposes. See “Use of Proceeds.”

Lock-up Agreements		Our executive officers and directors have agreed with the placement agent not to sell, transfer or dispose of any shares or similar securities for a period of 60 days after the date of this prospectus. For additional information regarding our arrangement with the placement agent, please see “Plan of Distribution.”

Reverse Stock Split		On June 10, 2025, we effected a 1-for-6 reverse stock split of our outstanding common stock. Unless otherwise noted, the share and per share information in this prospectus reflects the effect of the reverse stock split. However, our Annual Report on Form 10-K for the year ended December 31, 2024, filed on February 26, 2025, and all other documents incorporated by reference into this prospectus that were filed prior to June 10, 2025, do not give effect to reverse stock split.

Nasdaq Trading Symbol		Our common stock is listed on the Nasdaq Capital Market under the symbol “BBLG.” We do not intend to list the pre-funded warrants or warrants offered hereunder on any stock exchange. Without an active trading market, the liquidity of the pre-funded warrants and warrants will be limited.

Risk Factors		See “Risk Factors” on page 10 and other information included or incorporated by reference in this prospectus for a discussion of factors to consider carefully before deciding to invest in our securities.

The discussion above is based on 545,260 shares of our common stock outstanding as of June 20, 2025, and excludes as of such date the following:

	●	87,856 shares of common stock issuable upon exercise of stock options outstanding at a weighted average exercise price of $105.73 per share.

	●	309,037 shares of common stock issuable upon exercise of outstanding common stock warrants with a weighted average exercise price of $93.23 per share.

	●	5,017,059 shares of common stock reserved for future grants pursuant to the Bone Biologics Corporation 2015 Equity Incentive Plan (the “2015 Equity Incentive Plan”).

	●	2,500,000 shares of our common stock issuable upon the exercise of warrants to be issued in this offering; and

	●	75,000 shares of common stock issuable upon the exercise of the placement agent warrants to be issued to the placement agent or its designees as compensation in connection with this offering and pursuant to this prospectus.

Unless expressly indicated or the context requires otherwise, all information in this prospectus assumes (i) full exercise of the pre-funded warrants and (ii) no exercise of the warrants offered hereby.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should carefully consider all of the information contained in this prospectus and other information which may be incorporated by reference in this prospectus as provided under “Information Incorporated by Reference.” In particular, you should carefully consider the risks described below and elsewhere in this prospectus, which could materially and adversely affect our business, results of operations or financial condition, together with those under the heading “Risk Factors” in our most recent Annual Report on Form 10-K, which is incorporated by reference into this prospectus, as those risk factors are amended or supplemented by our subsequent filings with the SEC. These risks and uncertainties are not the only risks and uncertainties we face. Additional risks and uncertainties not currently known to us, or that we currently view as immaterial, may also impair our business. If any of the risks or uncertainties described below or in our SEC filings or any additional risks and uncertainties actually occur, our business, financial condition, results of operations and cash flow could be materially and adversely affected. As a result, you could lose all or part of your investment.

Risks Related to This Offering and Ownership of our Securities

Our recurring operating losses have raised substantial doubt regarding our ability to continue as a going concern.

Our recurring operating losses raise substantial doubt about our ability to continue as a going concern. During the year ended December 31, 2024, we incurred a net loss of $4.1 million and used net cash in operating activities of $4.1 million. Our available cash is expected to fund our operations up to the fourth quarter of 2025. In addition, our independent registered public accounting firm, in its audit report to the financial statements as of and for the year ended December 31, 2024, expressed substantial doubt about our ability to continue as a going concern. Our financial statements do not include any adjustments that might result if we are unable to continue as a going concern and, therefore, be required to realize our assets and discharge our liabilities other than in the normal course of business which could cause investors to suffer the loss of all or a substantial portion of their investment. In order to have sufficient cash and cash equivalents to fund our operations in the future, we will need to raise additional equity or debt capital and cannot provide any assurance that we will be successful in doing so. The perception of our ability to continue as a going concern may make it more difficult for us to obtain financing for the continuation of our operations and could result in the loss of confidence by investors, suppliers and employees.

The price of our common stock and public warrants may fluctuate substantially.

You should consider an investment in our common stock to be risky. Some factors that may cause the market price of our common stock to fluctuate, in addition to the other risks mentioned in this “Risk Factors” section are:

	●	our ability to meet the Nasdaq listing requirements;
	●	volatility and limitations in trading volumes of our shares of common stock;
	●	our ability to obtain financing to conduct and complete research and development activities including, but not limited to, our clinical trials, and other business activities;
	●	the timing and success of our clinical trials and introduction of products to the market;
	●	changes in the development status of our product candidate;
	●	any delays or adverse developments or perceived adverse developments with respect to the FDA’s review of our planned preclinical and clinical trials;
	●	safety concerns related to the use of our product candidate;
	●	changes in our capital structure or dividend policy, future issuances of securities, sales of large blocks of common stock by our stockholders;
	●	our cash position;
	●	announcements and events surrounding financing efforts, including debt and equity securities;
	●	changes in general economic, political and market conditions in or any of the regions in which we conduct our business;
	●	analyst research reports, recommendation and changes in recommendations, price targets, and withdrawals of coverage;
	●	departures and additions of key personnel;
	●	disputes and litigation;
	●	changes in applicable laws, rules, regulations, or accounting practices and other dynamics; and
	●	other events or factors, many of which may be out of our control.

In addition, if the market for stock in our industry or industries related to our industry, or the stock market in general, experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition and results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management.

Future sales and issuances of our common stock or equity-linked securities could result in additional dilution of the percentage ownership of our stockholders and could cause our share price to fall.

Following this offering we expect that significant additional capital will be needed in the future to continue our planned operations, including increased marketing, hiring new personnel, commercializing our product, and continuing activities as an operating public company. To the extent we raise additional capital by issuing common stock, or securities convertible into or exchangeable or exercisable for shares of common stock, our stockholders, including investors who purchase shares of common stock or pre-funded warrants in this offering, may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. Such sales may also result in material dilution to our stockholders, and new investors could gain rights superior to our existing stockholders, including investors who purchase shares of common stock or pre-funded warrants in this offering. Moreover, the perceived risk of this potential dilution could cause stockholders to attempt to sell their shares and investors to short our common stock. These sales also may result in downward pressure on the price of our common stock and make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem reasonable or appropriate, and may cause you to lose the value of your investment.

The warrants are speculative in nature.

The warrants do not confer any rights of common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of common stock at a fixed price for a limited time. Moreover, following this offering the market value of the warrants, if any, will be uncertain and there can be no assurance that the market value of the warrants will equal or exceed their imputed offering price. The warrants will not be listed or quoted for trading on any market or exchange. There can be no assurance that the market price of our common stock will ever equal or exceed the exercise price of the warrants, and consequently, the warrants may expire valueless.

There is no public market for the pre-funded warrants or warrants offered by us.

There is no established public trading market for the pre-funded warrants or warrants and we do not expect such a market to develop. In addition, we do not intend to apply to list the pre-funded warrants or warrants on any national securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the pre-funded warrants and warrants will be limited.

Holders of the warrants and pre-funded warrants will have no rights as common stockholders until they acquire our common stock.

Until holders of the warrants or pre-funded warrants acquire shares of our common stock upon exercise of the warrants or pre-funded warrants, the holders will have no rights with respect to shares of our common stock issuable upon exercise of the warrants or pre-funded warrants. Upon exercise of the warrants or pre-funded warrants, the holder will be entitled to exercise the rights of a common stockholder as to the security exercised only as to matters for which the record date occurs after the exercise.

Our management will have broad discretion over the use of the proceeds we receive in this offering and might not apply the proceeds in ways that increase the value of your investment.

Our management will have broad discretion in the application of the net proceeds from this public offering, including for any of the currently intended purposes described in the section entitled “Use of Proceeds.” Because of the number and variability of factors that will determine our use of the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management may not apply our cash from this offering in ways that ultimately increase the value of any investment in our securities or enhance stockholder value. The failure by our management to apply these funds effectively could harm our business. Pending their use, we may invest the net proceeds from this offering in short-term, investment-grade, interest-bearing securities. These investments may not yield a favorable return to our stockholders. If we do not invest or apply our cash in ways that enhance stockholder value, we may fail to achieve expected financial results, which may result in a decline in the price of our shares of common stock, and, therefore, may negatively impact our ability to raise capital, invest in or expand our business, acquire additional products or licenses, commercialize our product, or continue our operations.

If you purchase securities in this offering, you will suffer immediate dilution of your investment.

You will incur immediate and substantial dilution as a result of this offering. The public offering price per share of common stock and accompanying warrants and the public offering price per pre-funded warrant and accompanying warrants will be substantially higher than the as adjusted net tangible book value per share of our common stock after giving effect to this offering. Therefore, if you purchase securities in this offering, you will pay a price per share of common stock you acquire that substantially exceeds our net tangible book value per share after this offering. Based on an effective public offering price of $4.00 per share of common stock and accompanying warrants, and our net tangible book value as of March 31, 2025, you will experience immediate dilution of $0.01 per share, representing the difference between our as adjusted net tangible book value per share after giving effect to this offering and the public offering price.

Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including: (i) timely delivery of shares; (ii) agreement to not enter into variable rate financings for one year from closing, subject to certain exceptions; (iii) agreement to not enter into any financings for 60 days from closing; and (iv) indemnification for breach of contract.

This is a best efforts offering, with no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth above. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds, which may not be available or available on terms acceptable to us.

Because there is no minimum required for the offering to close, investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue the business goals outlined in this prospectus.

We have not specified a minimum offering amount nor have or will we establish an escrow account in connection with this offering. Because there is no escrow account and no minimum offering amount, investors could be in a position where they have invested in our company, but we are unable to fulfill our objectives due to a lack of interest in this offering. Further, because there is no escrow account in operation and no minimum investment amount, any proceeds from the sale of securities offered by us will be available for our immediate use, despite uncertainty about whether we would be able to use such funds to effectively implement our business plan. Investor funds will not be returned under any circumstances whether during or after the offering.

There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq, a failure of which could result in a delisting of our common stock and certain warrants.

Nasdaq requires that the trading price of listed stock remain above $1 in order for the stock to remain listed. If a listed stock trades below $1 for more than 30 consecutive trading days, then it is subject to delisting from the Nasdaq. In addition, to maintain a listing on Nasdaq, we must satisfy minimum financial and other continued listing standards, including those regarding minimum stockholders’ equity, minimum publicly available shares, director independence and independent committee requirements and other corporate governance requirements. As of the close of business on June 24, 2025, we believe we are currently in compliance with Nasdaq’s listing standards, but have not received written confirmation that we regained compliance from Nasdaq. If we are unable to satisfy these standards, we could be subject to delisting, which would have a negative effect on the price of our common stock, impair your ability to sell or purchase our common stock or warrants when you wish to do so, and potentially cause you to lose the value of your investment in us. In the event of a delisting, we would expect to take actions to restore our compliance with the listing standards, but we can provide no assurance that any action we take to restore our compliance would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the minimum bid price requirement, or prevent future noncompliance with the listing requirements.

If the Company is delisted from Nasdaq, its common stock may be eligible for trading on an over-the-counter market. If the Company is not able to obtain a listing on another stock exchange or quotation service for its common stock, it may be extremely difficult or impossible for stockholders to sell their shares of common stock. Moreover, if the Company is delisted from Nasdaq, but obtains a substitute listing for its common stock, it will likely be on a market with less liquidity, and therefore experience potentially more price volatility than experienced on Nasdaq. Stockholders may not be able to sell their shares of common stock on any such substitute market in the quantities, at the times, or at the prices that could potentially be available on a more liquid trading market. As a result of these factors, if the Company’s common stock is delisted from Nasdaq, the value and liquidity of the Company’s common stock would likely be significantly adversely affected. A delisting of the Company’s common stock from Nasdaq could also adversely affect the Company’s ability to obtain financing for its operations and/or result in a loss of confidence by investors, employees and/or business partners.

We received a deficiency letter from Nasdaq notifying us that we were not in compliance with its listing standards. If we are unable to regain compliance with Nasdaq’s listing standards, our securities will be delisted, which would negatively impact our common stock’s market price and liquidity and reduce our ability to raise capital.

On April 7, 2025, we received a deficiency letter from Nasdaq notifying us that, because the bid price of our common stock closed below $1 per share for 30 consecutive business days, we were no longer in compliance with the Bid Price Rule. We completed a 1-for-6 reverse stock split on June 10, 2025, and as of the close of business on June 24, 2025, we believe we have regained compliance with the Bid Price Rule because we have maintained a minimum bid price of at least $1 per share for 10 consecutive business days, but we have not received written confirmation that we regained compliance from Nasdaq.

We cannot assure you that we will be able to regain compliance with the Bid Price Rule and maintain compliance with Nasdaq’s other continued listing standards. Accordingly, our common stock and certain warrants could be delisted from Nasdaq. We and holders of our securities could be materially adversely impacted if our securities are delisted from Nasdaq. In particular:

	●	we may be unable to raise equity capital on acceptable terms or at all;
	●	we may lose the confidence of our business partners, which would jeopardize our ability to continue our business as currently conducted;
	●	the price of our common stock will likely decrease as a result of the loss of market efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws;
	●	holders may be unable to sell or purchase our securities when they wish to do so;
	●	we may become subject to stockholder litigation;
	●	we may lose the interest of institutional investors in our common stock;
	●	we may lose media and analyst coverage;
	●	our common stock could be considered a “penny stock,” which would likely limit the level of trading activity in the secondary market for our common stock; and
	●	we would likely lose any active trading market for our common stock, as it may only be traded on one of the over-the-counter markets, if at all.

We cannot assure you that the reverse stock split will increase the price of our common stock.

On June 10, 2025, we effected a 1-for-6 reverse stock split of our outstanding common stock. Unless otherwise noted, the share and per share information in this prospectus reflects the effect of the reverse stock split. We expect that the reverse stock split will increase the market price of our common stock. However, the effect of the reverse stock split on the market price of our common stock cannot be predicted with any certainty, and the history of reverse stock splits for other companies of similar size to us is varied, particularly because investors may view a reverse stock split negatively. We have effected reverse stock splits in the past; however, the price of our common stock did not remain at the elevated price for an extended period of time following the reverse stock split. It is possible that the per share price of our common stock after the reverse stock split will not increase in the same proportion as the reduction in the number of outstanding shares of common stock following the reverse stock split, and the reverse stock split may not result in a per share price that would attract investors who do not trade in lower-priced securities. In addition, we cannot assure you that our common stock will be more attractive to investors. The market price of our common stock may decrease due to factors unrelated to the reverse stock split, including our future performance, similar to the prior reverse stock split by the Company. If the trading price of our common stock declines, the percentage decline as an absolute number and as a percentage of our overall market capitalization may be greater than would have occur in the absence of the reverse stock split.

We do not intend to pay cash dividends on our shares of common stock so any returns will be limited to the value of our shares.

We currently anticipate that we will retain future earnings, if any, for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the increase, if any, of our share price.

The right of our President and Chief Executive Officer and Chief Financial Officer to participate in future financings of ours could impair our ability to raise capital.

Jeffrey Frelick, our President and Chief Executive Officer, and Deina Walsh, our Chief Financial Officer, hold contractual preemptive rights which allow them to participate, at their option, in all future financings up to an amount necessary to maintain their percentage interest in our common stock. The existence of such preemptive rights, or the exercise of such rights, may deter potential investors from providing us needed financing, or may deter investment banks from working with us. This may have a material adverse effect on our ability to raise capital which, in turn, could have a material adverse effect on our business prospects.

If our shares of common stock become subject to the penny stock rules, it would become more difficult to trade our shares.

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. If we do not retain a listing on Nasdaq and if the price of our common stock is less than $5.00, our common stock will be deemed a penny stock. The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that before effecting any transaction in a penny stock not otherwise exempt from those rules, a broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive (i) the purchaser’s written acknowledgment of the receipt of a risk disclosure statement; (ii) a written agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for our common stock, and therefore stockholders may have difficulty selling their shares.

Risks Related to our Intellectual Property

We rely on patents and patent applications and various regulatory exclusivities to protect some of our product candidates, and our ability to compete may be limited or eliminated if we are not able to protect our products.

The patent positions of medical device companies are uncertain and involve complex legal and factual questions. We plan to file a patent application with the 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. If our patent application is not approved by the USPTO, we may not be able to protect our product candidates.

We may incur significant expenses in protecting our intellectual property and defending or assessing claims with respect to intellectual property owned by others. Any patent or other infringement litigation by or against us could cause us to incur significant expenses and divert the attention of our management.

Others may file patent applications or obtain patents on similar technologies that compete with our products. We cannot predict how broad the claims in any such patents or applications will be and whether they will be allowed. Once claims have been issued, we cannot predict how they will be construed or enforced. We may infringe upon intellectual property rights of others without being aware of it. If another party claims we are infringing their technology, we could have to defend an expensive and time consuming lawsuit, pay a large sum if we are found to be infringing, or be prohibited from selling or licensing our products unless we obtain a license or redesign our products, which may not be possible.

We also rely on trade secrets and proprietary know-how to develop and maintain our competitive position. Some of our current or former employees, consultants, scientific advisors, contractors, current or prospective corporate collaborators, may unintentionally or willfully disclose our confidential information to competitors or use our proprietary technology for their own benefits. Furthermore, enforcing a claim alleging the infringement of our trade secrets would be expensive and difficult to prove, making the outcome uncertain. Our competitors may also independently develop similar knowledge, methods, and know-how or gain access to our proprietary information through some other means.

Risks Relating to Our Financial Position and Capital Needs

Our limited operating history makes it difficult to evaluate our current business and future prospects.

We have a limited operating history, and there is a risk that we will be unable to continue as a going concern. We have minimal assets and no significant financial resources. Our limited operating history makes it difficult to evaluate our current business model and future prospects. Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by companies in the early stages of development. Potential investors should carefully consider the risks and uncertainties that a company with a limited operating history will face. In particular, potential investors should consider that there is a significant risk that we will not be able to, among other things:

	●	implement or execute our current business plan, which may or may not be sound;

	●	maintain our anticipated management and advisory team;

	●	raise sufficient funds in the capital markets to effectuate our business plan; and

	●	utilize the funds that we do have and/or raise in the future to efficiently execute our business strategy.

If we cannot execute any one of the foregoing or similar matters relating to our business, the business may fail, in which case you would lose the entire amount of your investment in us.

Our long-term capital requirements are subject to numerous risks.

We anticipate that we will need to raise substantial additional funds to achieve FDA approval, if possible, for a spine interbody fusion indication, including costs related to a pivotal clinical trial prior to marketing our first product. Our long-term capital requirements will depend on many factors, including, among others:

	●	the number of potential formulations, products and technologies in development;

	●	continued progress and cost of our research and development programs;

	●	progress with pre-clinical studies and clinical trials;

	●	time and costs involved in obtaining regulatory (including FDA) clearance;

	●	costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims;

	●	costs of developing sales, marketing and distribution channels and our ability to sell our formulations or products;

	●	costs involved in establishing manufacturing capabilities for commercial quantities of our products;

	●	competing technological and market developments;

	●	market acceptance of our device formulations or products;

	●	costs for recruiting and retaining employees and consultants;

	●	costs for training physicians;

	●	legal, accounting and other professional costs; and

	●	the effect of the novel coronavirus will have on our product development, clinical trials, and availability, cost, and type of financing.

In addition, due to the numerous risks and uncertainties associated with product development, including that our product candidates may not advance through development or achieve the endpoints of applicable clinical trials, we are unable to predict the timing or amount of expenses, or when or if we will generate revenue and ultimately be able to achieve or maintain profitability. We may consume available resources more rapidly than currently anticipated, resulting in the need for additional funding. We may seek to raise any necessary additional funds through equity or debt financings, collaborative arrangements with corporate partners or other sources, which may be dilutive to existing stockholders or otherwise have a material effect on our current or future business prospects. If adequate funds are not available, we may be required to significantly reduce or refocus our development and commercialization efforts with regard to our delivery technologies and our proposed formulations and products.

We have incurred losses since inception and we expect our operating expenses to increase in the foreseeable future, which may make it more difficult for us to achieve and maintain profitability.

We have no significant operating history and since inception to March 31, 2025 have incurred accumulated losses of approximately $86.0 million. We will continue to incur significant expenses for development activities for our lead product candidate NELL-1/DBM.

We will continue to attempt to raise additional capital through debt and/or equity financing to provide additional working capital and fund future operations. 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. As a result, we can provide no assurance as to whether or if we will ever be profitable. If we are not able to achieve and maintain profitability, the value of our company and our common stock could decline significantly.

We face a number of risks associated with the incurrence of substantial debt which could adversely affect our financial condition.

If we incur a substantial amount of debt, we may be required to use a significant portion of any cash flow to pay principal and interest on the debt, which will reduce the amount available to fund working capital, capital expenditures, and other general purposes. Any indebtedness may negatively impact our ability to operate our business and limit our ability to borrow additional funds by increasing our borrowing costs, and impact the terms, conditions, and restrictions contained in possible future debt agreements, including the addition of more restrictive covenants; impact our flexibility in planning for and reacting to changes in our business as covenants and restrictions contained in possible future debt arrangements may require that we meet certain financial tests and place restrictions on the incurrence of additional indebtedness and place us at a disadvantage compared to similar companies in our industry that have less debt.

USE OF PROCEEDS

We estimate that the net proceeds from this offering if 100% of the securities in this offering are sold will be approximately $4.3 million after deducting estimated placement agent fees and estimated offering expenses payable by us and assuming full exercise of the pre-funded warrants and no exercise of the warrants.

We intend to use the net proceeds from this offering in the following order of priority: to fund clinical trials, maintain and extend our patent portfolio, and for working capital and other general corporate purposes. The actual allocation of proceeds realized from this offering will depend upon our cash position and working capital requirements. Therefore, as of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering. Accordingly, we will have discretion in the application of the net proceeds, and investors will be relying on our judgment regarding the application of the proceeds of this offering. Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments and U.S. government securities.

CAPITALIZATION

The following table sets forth our capitalization as of March 31, 2025 as follows:

	●	on an actual basis;
	●	on an as adjusted basis to reflect the issuance and sale by us of 793,750 shares of common stock and accompanying warrants at a public offering price of $4.00 per share and accompanying warrants and 456,250 pre-funded warrants to purchase 456,250 shares of common stock at a public offering price of $3.999 per pre-funded warrant and accompanying warrants in this offering and after deducting placement agent fees and estimated offering expenses payable by us, and assuming full exercise of the pre-funded warrants in this offering, no exercise of warrants being offered in this offering, that no value is attributed to such warrants and that such warrants are classified as and accounted for as equity.

The information below is illustrative only. Our capitalization following the closing of this offering will change based on how many securities are sold in the offering, the actual public offering price and other terms of this offering determined at pricing. You should read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and related notes included in the Form 10-K for the year ended December 31, 2024 and subsequent quarterly and annual reports, which are incorporated by reference in this prospectus.

	●	45,902 shares of common stock issuable upon exercise of stock options outstanding;
	●	309,016 shares of common stock issuable upon exercise of outstanding common stock warrants;
	●	59,180 shares of common stock reserved for future grants pursuant to our 2015 Equity Incentive Plan;

DILUTION

If you invest in our securities in this offering, your ownership interest will be immediately diluted to the extent of the difference between the combined public offering price per share and accompanying warrants and the as adjusted net tangible book value per share of our common stock immediately after this offering.

As of March 31, 2025, we had a historical net tangible book value of $2,910,902, or $5.34 per share of common stock, based on 545,260 shares of common stock outstanding at March 31, 2025. Our historical net tangible book value per share is the amount of our total tangible assets less our total liabilities at March 31, 2025, divided by 545,260 shares of common stock.

The information discussed below is illustrative only. You should read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the financial statements and related notes in the Form 10-K for the year ended December 31, 2024 and subsequent quarterly and annual reports, which are incorporated by reference in this prospectus.

After giving effect to the sale of (i) 793,750 shares of common stock and accompanying warrants at a public offering price of $4.00 and (ii) pre-funded warrants to purchase 456,250 shares of common stock and accompanying warrants at a public offering price of $3.999 in this offering and after deducting placement agent fees and estimated offering expenses payable by us, and assuming full exercise of the pre-funded warrants in this offering, no exercise of the warrants being offered in this offering, that no value is attributed to such warrants and that such warrants are classified as and accounted for as equity, our as adjusted net tangible book value as of March 31, 2025 would have been approximately $7,163,792 or approximately $3.99 per share of common stock. This amount represents an immediate decrease in the net tangible book value after this offering of $1.35 per share to our existing stockholders and an immediate dilution of $0.01 per share to investors participating in this offering. We determine dilution per share to investors participating in this offering by subtracting the as adjusted net tangible book value per share after giving effect to this offering from the public offering price per share and accompanying warrants paid by investors participating in this offering. The following table illustrates this dilution:

Public offering price per share and accompanying warrants				$	4.00
Historical net tangible book value per share as of March 31, 2025	$	5.34

Decrease in net tangible book value per share attributable to new investors	$	(1.35	)
As adjusted net tangible book value per share after this offering					3.99
Immediate dilution in net tangible book value per share to new investors				$	0.01

We may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

The number of shares of our common stock outstanding set forth in the table above excludes, as of March 31, 2025:

	●	45,902 shares of common stock issuable upon exercise of stock options outstanding;
	●	309,016 shares of common stock issuable upon exercise of outstanding common stock warrants;
	●	59,013 shares of common stock reserved for future grants pursuant to our 2015 Equity Incentive Plan;
	●	2,500,000 shares of our common stock issuable upon the exercise of the warrants to be issued in this offering; and
	●	75,000 shares of our common stock issuable upon the exercise of the placement agent warrants to be issued in this offering.

DESCRIPTION OF SECURITIES

The following description of our capital stock and provisions of our Amended and Restated Certificate of Incorporation, as amended (“Certificate of Incorporation”), and Amended and Restated Bylaws, as amended (“Bylaws”), is only a summary. You should also refer to our Certificate of Incorporation, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part, and our Bylaws, a copy of which is filed as an exhibit to the registration statement of which this prospectus is a part.

General

Our Certificate of Incorporation authorizes the issuance of up to 100,000,000 shares of common stock, par value $0.001 per share, and up to 20,000,000 shares of preferred stock, par value $0.001 per share. As of June 20, 2025, there were 22 shareholders of record of our common stock. The actual number of holders of our common stock is greater than this number of record holders, and includes shareholders who are beneficial owners, but whose shares are held in street name by brokers or held by other nominees. This number of holders of record also does not include shareholders whose shares may be held in trust by other entities.

Common Stock

Each holder of common stock is entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. An election of directors by our stockholders will be determined by a plurality of the votes cast by the stockholders entitled to vote on the election. All other actions by stockholders will be approved by the majority of the votes cast affirmatively or negatively (excluding abstentions and broker non-votes) except as otherwise required by law.

Holders of common stock are entitled to receive proportionately any dividends that may be declared by our Board of Directors, subject to any preferential dividend rights of any series of preferred stock that we may designate and issue. In the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately our net assets available for distribution to stockholders after the payment of all debts and other liabilities and subject to the preferential rights of any outstanding preferred stock.

Holders of our common stock have no preemptive, subscription, redemption, or conversion rights. The rights, preferences, and privileges of holders of common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of preferred stock that we may designate and issue.

Preferred Stock

Under our Certificate of Incorporation, our Board of Directors has the authority, without further action by stockholders, to designate one or more series of preferred stock and to fix the voting powers, designations, preferences, limitations, restrictions, and relative rights granted to or imposed upon the preferred stock, including dividend rights, conversion rights, voting rights, rights and terms of redemption, liquidation preference, and sinking fund terms, any or all of which may be preferential to or greater than the rights of the common stock.

The authority possessed by our Board of Directors to issue preferred stock could potentially be used to discourage attempts by third parties to obtain control of our company through a merger, tender offer, proxy contest, or otherwise by making such attempts more difficult or more costly. Our Board of Directors may issue preferred stock with voting rights, conversion rights, and other rights that, if exercised, could adversely affect the voting power of the holders of common stock.

Warrants

The following summary of certain terms and provisions of the Series D Warrants and Series E Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of warrants, the forms of which are filed as exhibits to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the forms of warrant for a complete description of the terms and conditions of the warrants.

Duration and Exercise Price. The Series D Warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series D Warrants will expire on the five-year anniversary of the date of issuance. The Series E warrants will have an exercise price of $4.00 per share and will be exercisable upon issuance. The Series E Warrants will expire on the 18-month anniversary of the date of issuance. The exercise price and number of shares of common stock issuable upon exercise of the warrants is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The warrants will be issued separately from the common stock and pre-funded warrants and may be transferred separately immediately thereafter. The warrants will be issued in certificated form only.

Exercise Limitation. The warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of such holder’s warrants to the extent that the holder would own more than 4.99% of the outstanding common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s warrants up to 9.99% of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the warrants..

Cashless Exercise. If, at the time a holder exercises its warrants, a registration statement registering the issuance or resale of the shares of common stock underlying the warrants under the Securities Act of 1933, as amended (the “Securities Act”), is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the warrant.

Fractional Shares. No fractional shares of common stock will be issued upon the exercise of the warrants. Rather, the number of shares of common stock to be issued will, at our election, either be rounded up to the next whole share or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Transferability. Subject to applicable laws, a warrant may be transferred at the option of the holder upon surrender of the warrant to us together with the appropriate instruments of transfer.

Trading Market. There is no established trading market for the warrants, and we do not expect such a market to develop. We do not intend to apply to list the warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the warrants will be extremely limited.

Fundamental Transactions. In the event of a fundamental transaction, as described in the warrants and generally including any reorganization, recapitalization or reclassification of our shares of common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of 50% or more of the voting power represented by our outstanding shares of capital stock, any person or group becoming the beneficial owner of 50% or more of the voting power represented by our outstanding shares of capital stock, any merger with or into another entity or a tender offer or exchange offer approved by more than 50% of the voting power represented by our outstanding shares of capital, then upon any subsequent exercise of a warrant, the holder will have the right to receive as alternative consideration, for each share of our common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of our common stock for which the warrant is exercisable immediately prior to such event. Notwithstanding the foregoing, in the event of a fundamental transaction, the holders of the warrants have the right to require us or a successor entity to redeem the warrants for cash in the amount of the Black-Scholes Value (as defined in each warrant) of the unexercised portion of the warrants concurrently with or within 30 days following the consummation of a fundamental transaction. However, in the event of a fundamental transaction which is not in our control, including a fundamental transaction not approved by our Board, the holders of the warrants will only be entitled to receive from us or our successor entity, as of the date of consummation of such fundamental transaction the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of the warrant that is being offered and paid to the holders of our common stock in connection with the fundamental transaction, whether that consideration is in the form of cash, stock or any combination of cash and stock, or whether the holders of our common stock are given the choice to receive alternative forms of consideration in connection with the fundamental transaction.

Right as a Stockholder. Except as otherwise provided in the warrants or by virtue of such holder’s ownership of shares of our common stock, the holders of the warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their warrants.

Pre-Funded Warrants

The following summary of certain terms and provisions of the pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which will be filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.

Duration and Exercise Price. Each pre-funded warrant offered hereby will have an initial exercise price per share of common stock equal to $0.001. The pre-funded warrants will be immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of share dividends, share splits, reorganizations or similar events affecting our shares of common stock and the exercise price.

Exercise Limitation. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of common stock purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the pre-funded warrant to the extent that the holder would own more than 4.99% of the outstanding shares of common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of beneficial ownership of outstanding shares after exercising the holder’s pre-funded warrants up to 9.99% of the number of our shares of common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. Purchasers of pre-funded warrants in this offering may also elect prior to the issuance of the pre-funded warrants to have the initial exercise limitation set at 9.99% of our outstanding shares of common stock.

Cashless Exercise. In lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.

Fractional Shares. No fractional shares of common stock will be issued upon the exercise of the pre-funded warrants. Rather, at the Company’s election, the number of shares of common stock to be issued will be rounded up to the next whole share or the Company will pay a cash adjustment in an amount equal to such fraction multiplied by the exercise price.

Transferability. Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the pre-funded warrants to us together with the appropriate instruments of transfer.

Trading Market. There is no established trading market for the pre-funded warrants, and we do not expect such a market to develop. We do not intend to apply to list the pre-funded warrants on any securities exchange or other nationally recognized trading system. Without an active trading market, the liquidity of the pre-funded warrants will be extremely limited.

Fundamental Transaction. In the event of a fundamental transaction, as described in the pre-funded warrants and generally including any reorganization, recapitalization or reclassification of our shares of common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of 50% or more of the voting power represented by our outstanding shares of capital stock, any person or group becoming the beneficial owner of 50% or more of the voting power represented by our outstanding shares of capital stock, any merger with or into another entity or a tender offer or exchange offer approved by more than 50% of the voting power represented by our outstanding shares of capital, then upon any subsequent exercise of a pre-funded warrant, the holder will have the right to receive as alternative consideration, for each share of our common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of our company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of our common stock for which the pre-funded warrant is exercisable immediately prior to such event.

Right as a Stockholder. Except as otherwise provided in the pre-funded warrants or by virtue of such holder’s ownership of shares of common stock, the holders of the pre-funded warrants do not have the rights or privileges of holders of our shares of common stock, including any voting rights, until they exercise their pre-funded warrants. The pre-funded warrants will provide that the holders of the pre-funded warrants have the right to participate in distributions or dividends paid on our shares of common stock.

Placement Agent Warrants

We have also agreed to issue to the placement agent or its designees as compensation in connection with this offering, the placement agent warrants to purchase 75,000 shares of common stock at an exercise price of $5.00 per share (representing 125% of the offering price per share and accompanying warrants). The placement agent warrants will expire five years from the commencement of sales in this offering. Except as provided above, the placement agent warrants will have substantially the same terms as the warrants described herein. See “Plan of Distribution–Placement Agent Warrants.”

Anti-Takeover Effects of Our Certificate of Incorporation and Bylaws

Certain provisions of our Certificate of Incorporation and Bylaws contain provisions that could have the effect of delaying or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids.

Our Certificate of Incorporation and Bylaws include provisions that:

	●	authorize our Board of Directors to issue, without further action by the stockholders, up to 20,000,000 shares of preferred stock in one or more series designated by the Board of Directors;
	●	specify that meetings of our stockholders can be called only by our Board of Directors, or any officer instructed by the director to call the meeting; and
	●	provide that vacancies on our Board of Directors may be filled only by the vote of a majority of the remaining directors even though less than a quorum.

Our Bylaws also provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. To be timely, a stockholder’s notice must be delivered to the secretary at our principal executive offices not later than the close of business on the 90^th day nor earlier than the close of business on the 120^th day prior to the first anniversary of the preceding year’s annual meeting; provided, however, that in the event the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, or if no annual meeting was held in the preceding year, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120^th day prior to such annual meeting and not later than the close of business on the later of the 90^th day prior to such annual meeting or the 10^th day following the day on which a public announcement of the date of such meeting is first made by us. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Delaware Anti-Takeover Statute

We are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. In general, Section 203 prohibits a publicly-held Delaware corporation such as Bone Biologics Corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder unless:

	●	prior to the date of the transaction, the Board of Directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
	●	upon completion of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, but not for determining the outstanding voting stock owned by the interested stockholder, (1) shares owned by persons who are directors and also officers of the corporation and (2) shares owned by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
	●	at or subsequent to the date of the transaction, the business combination is approved by the Board of Directors of the corporation and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder.

In this context, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns or, within three years prior to the determination of interested stockholder status, did own 15% or more of a corporation’s outstanding voting stock. We expect the existence of this provision to have an anti-takeover effect with respect to transactions our Board of Directors does not approve in advance. We also anticipate that Section 203 may discourage business combinations or other attempts that might result in a premium over the market price for the shares of common stock held by our stockholders.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC.

Stock Market Listing

Our common stock is listed on Nasdaq under the symbol “BBLG.”

PLAN OF DISTRIBUTION

Pursuant to an engagement agreement, dated March 11, 2025 we have engaged H.C. Wainwright & Co., LLC, the placement agent, to act as our exclusive placement agent to solicit offers to purchase the securities offered pursuant to this prospectus on a best efforts basis. The engagement agreement does not give rise to any commitment by the placement agent to purchase any of our securities, and the placement agent will have no authority to bind us by virtue of the engagement agreement. The placement agent is not purchasing or selling any of the securities offered by us under this prospectus, nor is it required to arrange for the purchase or sale of any specific number or dollar amount of securities. This is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering. The placement agent has agreed to use reasonable best efforts to arrange for the sale of the securities by us. Therefore, we may not sell all of the shares of common stock, pre-funded warrants and warrants being offered. The terms of this offering are subject to market conditions and negotiations between us, the placement agent and prospective investors. The placement agent does not guarantee that it will be able to raise new capital in any prospective offering. The placement agent may engage sub-agents or selected dealers to assist with the offering.

Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including: (i) timely delivery of shares; (ii) agreement to not enter into variable rate financings for one year from closing, subject to certain exceptions; (iii) agreement to not enter into any financings for 60 days from closing; and (iv) indemnification for breach of contract. The nature of the representations, warranties and covenants in the securities purchase agreements shall include:

	●	standard issuer representations and warranties on matters such as organization, qualification, authorization, no conflict, no governmental filings required, current in SEC filings, no litigation, labor or other compliance issues, environmental, intellectual property and title matters and compliance with various laws such as the Foreign Corrupt Practices Act; and
	●	covenants regarding matters such as registration of warrant shares, no integration with other offerings, no stockholder rights plans, no material nonpublic information, use of proceeds, indemnification of purchasers, reservation and listing of shares of common stock, and no subsequent equity sales for 60 days.

We will deliver the securities being issued to the investors upon receipt of investor funds for the purchase of the securities offered pursuant to this prospectus. We expect to deliver the securities being offered pursuant to this prospectus on or about July 24, 2025. There is no minimum number of securities or amount of proceeds that is a condition to closing of this offering.

Fees and Expenses

We have agreed to pay the placement agent a total cash fee equal to 7.0% of the aggregate gross proceeds raised in the offering.

Placement Agent Warrants

In addition, we have agreed to issue to the placement agent or its designees warrants, or the placement agent warrants, to purchase up to 6.0% of the aggregate number of shares of common stock sold in this offering (including shares underlying any pre-funded warrants), at an exercise price equal to 125% of the public offering price per share and accompanying warrants to be sold in this offering. The placement agent warrants will be exercisable upon issuance and will expire five years from the commencement of sales under this offering.

If at the time of exercise there is no effective registration statement registering, or the prospectus contained therein is not available for the resale of warrant shares by the holders of the placement agent warrants, then the placement agent warrants may be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the holders shall be entitled to receive a number of warrant shares as calculated in the placement agent warrants.

The placement agent warrants provide for customary anti-dilution provisions (for share dividends, splits and recapitalizations and the like) consistent with FINRA Rule 5110.

The placement agent will only be entitled to such fee to the extent that the parties are directly introduced to us by the placement agent, in accordance with FINRA Rule 2010.
