EXPLANATORY NOTE

On February 24, 2026, FibroBiologics, Inc. filed its Annual Report on Form 10-K for the year ended December 31, 2025, or the 2025 Annual Report. The 2025 Annual Report omitted Part III, Items 10 (Directors, Executive Officers and Corporate Governance), 11 (Executive Compensation), 12 (Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters), 13 (Certain Relationships and Related Transactions, and Director

ii

------

Independence) and 14 (Principal Accountant Fees and Services) in reliance on General Instruction G(3) to Form 10-K, which provides that such information may be either incorporated by reference from the registrant's definitive proxy statement or included in an amendment to Form 10-K, in either case filed with the Securities and Exchange Commission, or the SEC, not later than 120 days after the end of the fiscal year.

This Amendment No. 1 to Form 10-K, or this Amendment, is being filed solely to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•amend Part III, Items 10, 11, 12, 13 and 14 of the 2025 Annual Report to include the information required by such items;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•delete the reference on the cover of the 2025 Annual Report to the incorporation by reference of portions of our proxy statement into Part III of the 2025 Annual Report; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•file new certifications of our principal executive officer and principal financial officer as exhibits to this Amendment under Item 15 of Part IV hereof, pursuant to Rule 12b-15 under the Securities Exchange Act of 1934.

Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. We are not including the certifications under Section 906 of the Sarbanes-Oxley Act of 2002 as no financial statements are being filed with this Amendment.

Except as described above, this Amendment does not modify or update disclosure in, or exhibits to, the 2025 Annual Report. Furthermore, this Amendment does not change any previously reported financial results, nor does it reflect events occurring after the date of the 2025 Annual Report. Information not affected by this Amendment remains unchanged and reflects the disclosures made at the time the 2025 Annual Report was filed. Accordingly, this Amendment should be read in conjunction with the 2025 Annual Report and our other filings with the SEC.

**SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS**

The 2025 Annual Report, this Amendment, and the documents incorporated by reference therein and herein, if any, contain forward-looking statements. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts contained in the 2025 Annual Report and this Amendment, including statements regarding our future results of operations and financial position, business strategy, prospective products, product approvals, research and development costs, future revenue, timing and likelihood of success, plans and objectives of management for future operations, future results of anticipated products and prospects, planned research programs, preclinical studies and clinical trials, and market opportunities are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

In some cases, you can identify forward-looking statements by terms such as "anticipate," "believe," "contemplate," "continue," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "should," "target," "will," or "would" or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. Forward-looking statements contained in the 2025 Annual Report and this Amendment include, but are not limited to, statements about:

● the timing, progress and results of preclinical studies and clinical trials for our current and future product candidates, including statements regarding the timing of initiation and completion of studies or trials and related preparatory work, the period during which the results of the trials will become available and our research and development programs;

● the timing, scope or likelihood of regulatory submissions, filings, and approvals, including final regulatory approval of our product candidates;

● our ability to develop and advance product candidates into, and successfully complete, clinical trials;

● our expectations regarding the size of the patient populations for our product candidates, if approved for commercial use;

i

------

● the implementation of our business model and our strategic plans for our business, product candidates and technology;

● our commercialization, marketing and manufacturing capabilities and strategy;

● the pricing and reimbursement of our product candidates, if approved;

● the rate and degree of market acceptance and clinical utility of our product candidates, in particular, and cell therapy, in general;

● our ability to establish or maintain collaborations or strategic relationships or obtain additional funding;

● our competitive position;

● the scope of protection we and/or our licensors are able to establish and maintain for intellectual property rights covering our product candidates;

● developments and projections relating to our competitors and our industry;

● our estimates regarding expenses, future revenue, capital requirements and needs for additional financing;

● the period over which we estimate our existing cash and cash equivalents will be sufficient to fund our future operating expenses and capital expenditure requirements; and

● the impact of laws and regulations.

We have based these forward-looking statements largely on our current expectations and projections about our business, the industry in which we operate and financial trends that we believe may affect our business, financial condition, results of operations and prospects, and these forward-looking statements are not guarantees of future performance or development. These forward-looking statements speak only as of the date of the 2025 Annual Report and this Amendment, as applicable, and are subject to a number of risks, uncertainties and assumptions described in the section titled "*Risk Factors*" and elsewhere in the 2025 Annual Report and this Amendment. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. You should read the 2025 Annual Report, this Amendment, the documents that we reference in the 2025 Annual Report and this Amendment, and the other documents that we file with the Securities and Exchange Commission, or the SEC, with the understanding that our actual future results may be materially different from any future results expressed or implied by these forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in the 2025 Annual Report and this Amendment, whether as a result of any new information, future events or otherwise.

In addition, statements that "we believe" and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of the 2025 Annual Report and this Amendment, as applicable, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and you are cautioned not to unduly rely upon these statements.

***2025 Salaries*** 

In 2025, our named executive officers received an annual base salary to compensate them for services rendered to us. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role, and responsibilities.

For fiscal year 2025, Mr. O'Heeron's annual base salary rate was $617,500, Dr. Khoja's annual base salary rate was $425,000, and Mr. Garcia's annual base salary rate was $425,000.

***2025 Bonuses*** 

For fiscal year 2025, each named executive officer was eligible to earn his bonus based on the attainment of pre-established annual company performance objectives, as determined by the Board in its discretion. Performance objectives for the company focused on preparing for and conducting a clinical trial, advancing regulatory pathways and filings, capital raising efforts and managing spend. Mr. O'Heeron was eligible to earn an annual cash bonus targeted at 55% of his base salary, or $339,625, Dr. Khoja was eligible to earn an annual cash bonus targeted at 40% of base salary, or $170,000, and Mr. Garcia was eligible to earn an annual cash bonus targeted at 40% of base salary, or $170,000. All of the named executive officers were eligible for an additional 50% of the bonus target if certain stretch goals relating to research and development activities and business development were achieved.

Annual bonuses are determined based upon the company performance for the fiscal year and are generally determined and paid out in the first quarter of the subsequent year. In January and February 2026, the Compensation Committee reviewed the named executive officers' performance against the 2025 goals, the company's financial position, available cash, and upcoming liquidity needs. Based on this review and in an effort to manage the company's liquidity needs, the Compensation Committee determined the named executive officers would not receive a bonus payment for 2025 performance. The Compensation Committee recognized the named executive officers' 2025 achievements in the face of limited resources, both human capital and financial.

***Role of Compensation Consultant***

For 2025, the Compensation Committee engaged a compensation consultant, Anderson Pay Advisors LLC, to provide the Compensation Committee with a competitive compensation assessment (cash and equity) for our non-employee directors, executives and broad-based employees and develop a compensation matrix covering base salary ranges, target bonus levels, and equity grant guidelines.

Under its charter, the Compensation Committee has the authority, in its sole discretion, to retain or obtain the advice of compensation consultants, legal counsel or other advisers, and it has direct responsibility for the appointment, compensation and oversight of the work of any such adviser. The Compensation Committee also has the right to receive from the Company appropriate funding for the payment of reasonable compensation to the adviser it retains.

***Role of our Management***

------

In general, our Chief Executive Officer and Chief Financial Officer work together to prepare materials requested by the Compensation Committee. Our Chief Executive Officer typically presents these materials, along with any background information, to the Compensation Committee for review and consideration. The Compensation Committee may approve, modify, or reject the proposals, or may request additional information from management or outside advisors or consultants on those matters.

For setting compensation levels for executives other than our Chief Executive Officer, the Compensation Committee will solicit and consider the recommendations of the Chief Executive Officer, including his review of the officer's performance and contributions in the prior year, and his recommendations for the potential compensation levels that should be set for each executive officer for the coming year.

No executive officer participates directly in approving the amount of any component of his or her own compensation package nor is present during those deliberations.

***Equity Compensation***

In connection with Mr. Garcia's commencement of service as General Counsel, Mr. Garcia also received a grant of 180,000 stock options under the 2022 Stock Plan, which grant vests as to 1/4 of the shares underlying the stock option on the first anniversary of Mr. Garcia's date of hire and 1/48<sup>th</sup>per month thereafter, generally subject to Mr. Garcia's continued employment through the applicable vesting date.

**Other Elements of Compensation** 

***Retirement Plans*** 

We participate in the Insperity 401(k) retirement savings plan, sponsored by Insperity Holdings, Inc., or the Insperity 401(k) plan, for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the Insperity 401(k) plan on the same terms as other full-time employees. In 2024 and 2025, contributions made by participants in the 401(k) plan were matched up to a specified percentage of the employee contributions on behalf of the named executive officers. These matching

------

contributions are fully vested as of the date on which the contribution is made. Our named executive officers continue to participate in this Insperity 401(k) plan on the same terms as other full-time employees.

● medical, dental and vision benefits;

● medical and dependent care flexible spending accounts;

● life insurance.

We subsidize the costs of medical, dental and vision benefits for our executive officers. We believe that the employee benefits described above are necessary and appropriate to provide a competitive compensation package to our named executive officers.

In addition, the non-employee director compensation policy provides that, upon initial election to the Board, each non-employee director will be granted an equity award the equivalent of 44,000 shares of common stock, or the Initial Grant. Furthermore, on the date of each of our annual meeting of stockholders, each non-employee director who continues as a non-employee director following such meeting will be granted an annual equity award of stock options, to purchase 22,000 shares, or the Annual Grant. The Annual Grant will vest in full upon the earlier of (i) the first anniversary of the date of grant or (ii) the date of the next annual meeting; *provided, however,* that all vesting shall cease if the director resigns from the Board or otherwise ceases to serve as a director, unless the Board determines that the circumstances warrant continuation of vesting. In addition, all vested options remain exercisable for 12 months if the director resigns from the Board or otherwise ceases to serve as a director. Notwithstanding the foregoing, if an outside director was initially elected to the Board within 12 months preceding the annual meeting, then such outside director shall receive an Annual Grant that is pro-rated on a monthly basis for time served as an outside director.

| **Item 12.** | **Secur** **ity Ownership of Beneficial Owners and Management and Related Stockholder Matters** |

---

The following table sets forth, as of March 13, 2026, certain information regarding the beneficial ownership of our voting securities (being our voting common stock and our Series C Preferred Stock) by (i) each person or group of affiliated persons known by us to be the beneficial owner of more than 5% of our voting securities, (ii) each of our named executive officers, (iii) each of our directors and (iv) all of our directors and executive officers as a group. Except as otherwise indicated, all persons listed below have (i) sole voting power and investment power with respect to their common stock and Series C Preferred Stock, as applicable, except to the extent that authority is shared by spouses under applicable law, and (ii) record and beneficial ownership with respect to their common stock and Series C Preferred Stock, as applicable.

In accordance with the rules of the SEC, beneficial ownership includes voting or investment power with respect to securities and includes the common stock issuable pursuant to options and warrants that are exercisable or settled within 60 days of March 13, 2026. Shares of common stock issuable pursuant to options and warrants are deemed outstanding for computing the percentage of the class beneficially owned by the person holding such securities but are not deemed outstanding for computing the percentage of the class beneficially owned by any other person.

In the table below, the percentage of beneficial ownership is based on, as applicable: (i) 68,156,883 shares of our Common Stock outstanding; and (ii) 2,500 shares of our Series C Preferred Stock outstanding, each as of March 13, 2026.

Each share of our Series C Preferred Stock is entitled to 13,000 votes per share and each share of our Common Stock is entitled to one vote per share. The percentage of total voting power in the table below is based on the sum of (i) 68,156,883 votes, being the total number of votes associated with 68,156,883 shares of our Common Stock (with each share of Common Stock having one vote) and (ii) 32,500,000 votes, being the total number of votes associated with 2,500 shares of Series C Preferred Stock (with each share of Series C Preferred Stock having 13,000 votes).

Unless otherwise indicated, the business address of each of the individuals and entities named below is c/o FibroBiologics, Inc., 455 E. Medical Center Blvd., Suite 300, Houston, Texas 77598.

**Certain Relationships and Related Transactions**

The following is a summary of transactions or series of transactions since inception, or currently proposed transactions or series of transactions, to which we were, or will be, a party, in which the amount involved exceeded, or will exceed, $120,000 (which is less than one percent of our average total assets for the last two completed fiscal years), and in which any of our directors, executive officers, or to our knowledge, beneficial owners of 5% or more of our capital stock or any member of the immediate family of, or entities affiliated with, any of the foregoing persons, had, or will have, a direct or indirect material interest, other than compensation arrangements, described under the section titled "Executive and Director Compensation" and indemnification agreements described below.

***Series A Preferred Stock***

In May 2021, as part our formation, we issued the equivalent of 8,750,000 shares of our Series A Preferred Stock to FibroGenesis in exchange for a Patent Assignment Agreement, which assigns certain patents/applications to us, and an Intellectual Property Cross-License Agreement, which provides to us an exclusive license within defined fields of use for patents/applications retained by FibroGenesis and provides to FibroGenesis an exclusive license to the patents/applications assigned to FibroBiologics for all other fields of use.

In connection with the Direct Listing, all of our outstanding shares of Series A Preferred Stock were automatically cancelled, without the payment of additional consideration by or to the holder thereof.

***Series C Preferred Stock***

In January 2024, in conjunction with our Direct Listing, we issued 2,500 shares of Series C Preferred Stock to our Chairperson and CEO for no consideration.

------

***FibroGenesis Loans***

In July 2022, we loaned $300,000 to FibroGenesis at 0% interest and one year maturity date. The $300,000 was fully repaid in April 2023.

***ROFN Agreement***

In January 2023, we entered into an Agreement Regarding Right of First Negotiation with FibroGenesis, or the ROFN Agreement. In exchange for FibroGenesis' consent to amend our certificate of incorporation to (i) eliminate upon our IPO or sale of our company, the liquidation preference for the Series A Preferred Stock, (ii) make the Series B Preferred Stock liquidation preference equal to that of the Series A Preferred Stock and (iii) provide that upon an IPO or sale of our company, the Series A Preferred Stock will be canceled for no consideration, we agreed to pay to FibroGenesis 15% of the gross proceeds from any equity investments in us prior to an IPO or sale of our company. In addition, we received a five-year right of first negotiation if FibroGenesis decides to license externally any of its technology. We paid a total of $2.8 million to FibroGenesis under the ROFN Agreement based upon gross proceeds from equity investments received through January 31, 2024, the date of our Direct Listing, and no further payments are due to FibroGenesis pursuant to the ROFN Agreement.

***2021 and 2022 Convertible Notes***

In December 2021, we issued and sold to investors, some of whom hold more than 5% of our capital stock, in a private placement $1.3 million of our convertible promissory notes, or the 2021 Notes. The 2021 Notes bore interest at an initial interest rate of 6.0% per annum and would have automatically converted into shares of our common stock in the event of a qualified financing. The conversion price of the 2021 Notes was equal to $200.0 million divided by the total number of equity interests outstanding prior to the dilution from the qualified financing. The 2021 Notes were unsecured and subordinated in right of payment to the prior payment in full to all of our commercial finance lenders, insurance companies, lease financing institutions or other lending institutions approved by the Board and regularly engaged in the business of lending money. In April 2023, $1.3 million of the 2021 Notes were converted into shares of our Series B Preferred Stock. The 2021 Notes are no longer outstanding.

In January 2022 and April 2022, we issued and sold to investors, some of whom hold more than 5% of our capital stock, in a private placement $0.35 million and $3.95 million, respectively, of our convertible promissory notes, or the 2022 Notes. The 2022 Notes bore interest at an initial rate of 6.0% per annum, had a one-year maturity, and were convertible at the holder's request into shares of our common stock in the event of a qualified financing. The conversion price of the 2022 Notes was the lesser of (i) a 15% discount to the offering price of our common stock in the event of an IPO or (i) the quotient of $200.0 million divided by total equity interests prior to the dilution from a qualified financing. The 2022 Notes were unsecured and subordinated in right of payment to the prior payment in full to all of our commercial finance lenders, insurance companies, lease financing institutions or other lending institutions approved by the Board and regularly engaged in the business of lending money. In February 2023 through June 2023, $4.3 million of the 2022 Notes were converted into shares of our Series B Preferred Stock. The 2022 Notes are no longer outstanding.

***Financing and Note Receivable***

On November 18, 2025, we entered into a securities purchase agreement, or the Purchase Agreement, with Golden Knight Incorporated, LP, or GK, pursuant to which (i) we issued and sold 3,540,000 shares of our common stock, $0.00001 par value per share, or the Common Stock, and pre-funded warrants to purchase up to an aggregate of 8,570,203 shares of Common Stock. The price of each share of Common Stock was $0.3303 per share and the price of each pre-funded warrant was $0.33029 (equal to the price per share of Common Stock, minus $0.00001, the exercise price of each pre-funded warrant). As a result of this transaction, GK became the beneficial owner of more than 5% of our Common Stock. Additionally, pursuant to the Purchase Agreement, we issued and sold to GK warrants to purchase one share of Common Stock for each share of Common Stock or pre-funded warrant purchased, for an

------

aggregate of 12,110,203 shares of Common Stock, or the Warrants. The exercise price of the Warrants is $0.3303 per share.

On January 14, 2026, GK exercised 1,075,000 pre-funded warrants for $17.50, and we issued 1,075,000 shares of Common Stock. On January 14, 2026, we issued a $400,000 note receivable to GK, which is due on January 14, 2027 and has an interest rate of 3.63%.

***Equity and Compensation Arrangements***

Our Board adopted on August 10, 2022, and our stockholders approved on August 18, 2022, our 2022 Stock Plan. The 2022 Stock Plan permits the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other stock awards. The 2022 Stock Plan, through the grant of stock and option awards, is intended to help us secure and retain the services of eligible award recipients, provide incentives for such persons to exert maximum efforts for our success and provide a means by which the eligible recipients may benefit from increases in value of our common stock. As of December 31, 2025, there were 6,783,761 shares available for future issuance under the 2022 Stock Plan.

**Indemnification Agreements** 

We have entered into indemnification agreements with each of our current directors and officers. These agreements provide for the indemnification of such persons for all reasonable expenses and liabilities incurred in connection with any action or proceeding brought against them by reason of the fact that they are or were serving in such capacity. We believe that these indemnification agreements are necessary to attract and retain qualified persons as directors and officers. Furthermore, we have obtained director and officer liability insurance to cover liabilities our directors and officers may incur in connection with their services to us.

**Director Independence**

The Board has determined that all members of the Board, except for Messrs. O'Heeron and Hoffman, are independent directors for purposes of the rules of Nasdaq and the SEC. In making this determination, the Board considered the relationships that each non-employee director has with us and all other facts and circumstances that the Board deemed relevant.
