Item 2: MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of financial condition and results of operations should be read together with the consolidated financial statements of Forte Biosciences, Inc. (“Forte”, “we”, “our”) and the accompanying notes appearing elsewhere in this Form 10-Q and in our Form 10-K as filed with the Securities and Exchange Commission, or SEC, on March 31, 2023. This discussion of the financial condition and results of operations regarding matters that are not historical facts, are forward-looking statements within the meaning of Section 21E of the Securities and Exchange Act of 1934, as amended, and the Private Securities Litigation Act of 1995 and, known as the PSLRA. These include statements regarding management’s intention, plans, beliefs, expectations or forecasts for the future, and, therefore, you are cautioned not to place undue reliance on them. No forward-looking statement can be guaranteed, and actual results may differ materially from those projected. The Company undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by law. We use words such as “anticipates,” “believes,” “plans,” “expects,” “projects,” “intends,” “may,” “will,” “should,” “could,” “estimates,” “predicts,” “potential,” “continue,” “guidance,” and similar expressions to identify these forward-looking statements that are intended to be covered by the safe-harbor provisions of the PSLRA.

Such forward-looking statements are based on our expectations and involve risks and uncertainties; consequently, actual results may differ materially from those expressed or implied in the statements due to a number of factors, including, but not limited to, risks relating to the sufficiency of the Company’s cash balance to fund the Company’s activities, and the expectations with respect thereto; the business and prospects of the Company; Forte’s plans to develop and potentially commercialize its product candidates, including FB-102; the timing of initiation of Forte’s planned preclinical studies and potential future clinical trials and the timing of the availability of data from such preclinical studies and potential future clinical trials; the timing of any planned investigational new drug application or new drug application; Forte’s plans to research, develop and commercialize its current and future product candidates; Forte’s ability to successfully enter into collaborations, and to fulfill its obligations under any such collaboration agreements; the clinical utility, potential benefits and market acceptance of Forte’s product candidates; Forte’s commercialization, marketing and manufacturing capabilities and strategy; Forte’s ability to identify additional products or product candidates with significant commercial potential; developments and projections relating to Forte’s competitors and its industry; the impact of government laws and regulations; Forte’s ability to protect its intellectual property position; Forte’s estimates regarding future revenue, expenses, capital requirements and need for additional financing; and the impact of COVID-19 on the Company, the Company’s industry or the economy generally.

The known risks and uncertainties are described in detail under the caption “Risk Factors” and elsewhere in this Form 10-Q, our Form 10-K filed with the SEC on March 31, 2023, and other SEC filings. Forward-looking statements included in this Form 10-Q are based on information available to Forte as of the date of this Form 10-Q. Accordingly, our actual results may materially differ from our current expectations, estimates and projections. Forte undertakes no obligation to update such forward-looking statements to reflect events or circumstances after the date of this presentation.

Overview

Forte Biosciences, Inc. and its subsidiaries (www.fortebiorx.com) (“Forte”, “we”, “our”) is a biopharmaceutical company that is advancing through preclinical trials its product candidate, FB-102, which is a proprietary molecule with potentially broad autoimmune applications in such indications as graft-versus-host disease (“GvHD”), vitiligo and alopecia areata (“AA”). The Company’s FB-102 program aims to address key pathways implicated in these indications.

GvHD is a complication that may occur after an allogeneic transplant and is where donor's T-cells attack the patient's healthy cells. There are 2 main types of GvHD – acute GvHD and chronic GvHD. The severity of symptoms range from mild to fatal. Acute GvHD usually occurs within 100 days of a transplant. Symptoms of the acute GvHD affect the skin, GI tract or liver. Chronic GvHD symptoms can occur any time after a transplant, but usually start within 2 years. Symptoms of chronic GvHD affect the skin, mouth, liver, lungs, GI tract, muscles or joints .There remains a significant unmet need for safe and effective therapies for GvHD.

14

Vitiligo is characterized by the loss of melanocytes which are cells that produce skin pigmentation​ and results in discolored patches appearing in the skin, hair and mucous membrane​. Vitiligo is believed to be mediated by natural killer cells (“NK cells”) and cytotoxic T lymphocytes (“CD8+ T cells”). Current treatments include black box warnings. There remains a significant unmet need for safe and effective therapies for vitiligo.

AA is characterized by nonscarring, unpredictable and patchy hair loss generally on the scalp but also in other areas of the body as a result of immune cells attacking and damaging hair follicles. There remains a significant unmet need for safe and effective therapies for AA​.

We had approximately $35.9 million in cash and cash equivalents as of March 31, 2023. Our common stock is publicly traded on the Nasdaq Capital Market under the ticker symbol FBRX. Prior to our merger with Tocagen, Inc., a publicly traded biotechnology company, Forte was a privately held company incorporated in Delaware on May 3, 2017.

In June 2021, Forte filed a shelf registration statement on Form S-3 that went effective in June 2021 which allowed Forte to raise up to $300 million in additional capital. On March 31, 2022, Forte entered into an “at-the-market” equity offering program (“ATM Facility”) whereby Forte may from time to time offer and sell shares of its common stock up to an aggregate offering price of $25.0 million during the term of the ATM Facility. On April 1, 2022, Forte filed a prospectus supplement to the June 2021 Form S-3 for the offer and sale of the shares under the ATM Facility covering sales of up to $7.0 million of shares of common stock. On August 12, 2022, Forte filed an additional prospectus supplement relating to offer and sell an additional $2.7 million of shares of common stock. Forte is currently eligible to sell securities under Form S-3 only if and to the extent the aggregate market value of securities sold by Forte pursuant to General Instruction I.B.6 of Form S-3 during the twelve-month period immediately prior to, and including, the date of any such sale, does not exceed one-third of the aggregate market value of Forte’s common stock held by non-affiliates (as determined by General Instruction I.B.6 of Form S-3), and Forte will remain subject to such limitation for so long as the aggregate market value of Forte’s common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3). As of the date of filing of this Quarterly Report on Form 10-Q, Forte has reached this limit and, as such, may not sell any additional securities under the ATM Facility (or otherwise under Form S-3) until such time as (i) during the preceding twelve-month period, we have not sold securities in excess of the limitation set forth in General Instruction I.B.6 of Form S-3, or (ii) the aggregate market value of our common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3). As such, while the ATM Facility remains in place, it is not currently a source of additional funding for Forte and Forte remains restricted in its ability to access additional funding from the sale of securities under Form S-3.

Intellectual Property

We own one US patent for administering a combination of Gram-positive and Gram-negative bacteria along with metabolites for treatment of a wide variety of skin conditions. The patent’s estimated expiration date is 2039. This patent is not material to Forte’s FB-102 program. We also own five pending US patent applications related to the FB-102 program. The estimated expiration dates of these patents are 2043-2044.

Macroeconomic Environment and COVID-19

Businesses throughout our industry have been and will continue to be impacted by a number of challenging and unexpected global and national events and circumstances that continue to evolve, including without limitation the COVID-19 pandemic, the war in Ukraine, increased economic uncertainty, inflation, rising interest rates, recent and any potential future financial institution failures, and other geopolitical tensions. The extent of the impact of these events and circumstances on our business, operations and development timelines and plans remains uncertain, and will depend on certain developments, including the duration and scope of the events and their impact on our development activities, third parties with whom we do business, as well as its impact on regulatory authorities and our key scientific and management personnel. We have been and continue to actively monitor the potential impacts that these various events and circumstances may have on our business and we take steps, where warranted, to minimize any potential negative impacts on our business resulting from these events and circumstances.

Components of Operating Results

Revenue

We have no products approved for commercial sale or in active development and have not generated any revenue from product sales. In the future, we may generate revenue from product sales, royalties on product sales, license fees, milestones, or other upfront payments if we enter into any collaborations or license agreements. We expect that our future revenue will fluctuate from quarter to quarter for many reasons, including the uncertain timing and amount of any such payments and sales.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development costs consist primarily of salaries and benefits of research and development personnel and costs related to research activities, preclinical studies, clinical trials and drug manufacturing. Non-refundable advance payments for goods or services that will be used in future research and development activities are deferred and capitalized and are only expensed when the goods have been received or when the service has been performed rather than when the payment is made.

Drug manufacturing and clinical trial costs are a component of research and development expenses. The Company expenses costs for its drug manufacturing activities performed by Contract Manufacturing Organizations (“CMOs”), costs for its preclinical and clinical trial activities performed by Contract Research Organizations (“CROs”) and other service providers, as they are incurred, based upon estimates of the work completed over the life of the individual study in accordance with associated agreements. The Company uses information it receives from internal personnel and outside service providers to estimate the percentage of completion and therefore the expense to be incurred.

We anticipate research and development expenses to continue to increase in the future as we develop our current lead product candidate, FB-102.

General and Administrative Expenses

General and administrative expenses consist primarily of professional fees such as legal, auditing, tax and business consulting services, personnel expenses and travel costs, costs associated with being a publicly traded company such as Sarbanes-Oxley compliance, accounting fees, and directors’ and officers’ liability insurance premiums. Our general and administrative expenses may increase due to increases in professional and advisory fees and as we build out our infrastructure to develop FB-102.

Other Income (Expense), Net

Other income (expense), net, consists of net foreign exchange gains and losses and franchise taxes, partially offset by interest earned on our cash and cash equivalents balances.

Critical Accounting Policies and Estimates

There have been no significant changes during the three months ended March 31, 2023 to our critical accounting policies, significant judgments and estimates as disclosed in our management’s discussion and analysis of financial condition and results of operations included in our Annual Report on our Form 10-K for the year ended December 31, 2022 as filed with the SEC on March 31, 2023.

Results of Operations

Comparison of Three months ended March 31, 2023 and 2022

The following tables summarize our results of operations for the three months ended March 31, 2023 and 2022 (in thousands):

16

Research and Development Expenses

Research and development expenses were $4.8 million for the three months ended March 31, 2023, compared to $0.7 million for the same period in 2022. The increase was primarily due to a net increase of approximately $3.4 million in manufacturing costs and a net increase of approximately $0.4 million in preclinical expenses as we ramp up our development of our FB-102 program, a net increase in payroll expenses of approximately $0.2 million, and net increase of approximately $0.1 million in other expenses.

We anticipate research and development expenses to increase in the future as we continue to develop our current lead product candidate, FB-102.

General and Administrative Expenses

General and administrative expenses were $2.1 million for the three months ended March 31, 2023, compared to $1.8 million for the same period in 2022. The increase was primarily due to an increase of $0.4 million in legal and professional fees, partially offset by a decrease of $0.2 million in stock-based compensation.

Our general and administrative expenses may increase in the future due to increases in professional and advisory fees as we build out our infrastructure to develop FB-102.

Other Income (Expenses), Net

The change in other income (expenses), net for the three ended March 31, 2023, compared with the same periods in the prior year were primarily driven by higher interest income earned from our cash and cash equivalents as a result of higher interest rates.

Liquidity and Capital Resources

We have no products approved for commercial sale and have not generated any revenue from product sales or out-licenses. We have never been profitable and have incurred operating losses each year since inception. Our net loss was approximately $6.8 million for the three months ended March 31, 2023. As of March 31, 2023, we had an accumulated deficit of approximately $93.8 million. We had cash and cash equivalents of approximately $35.9 million as of March 31, 2023. We believe that our existing cash and cash equivalents will be sufficient to allow us to fund our operations for at least 12 months from the filing date of this Form 10-Q. We expect to incur operating losses in the future as we develop our current lead product candidate, FB-102.

In June 2021, we filed a shelf registration statement on Form S-3 that went effective in June 2021 which will allow us to raise up to $300 million in additional capital. On March 31, 2022, we entered into an “at-the-market” equity offering program (“ATM Facility”) whereby we may from time to time offer and sell shares of our common stock up to an aggregate offering price of $25.0 million during the term of the ATM Facility. On April 1, 2022, we filed a prospectus supplement to the June 2021 Form S-3 relating to the offer and sale of shares under the ATM Facility covering sales of up to $7.0 million of shares of common stock. On August 12, 2022, we filed an additional prospectus supplement relating to the offer and sale of shares for an additional $2.7 million of shares of common stock. As discussed above, we are currently eligible to sell securities under Form S-3 only if and to the extent the aggregate market value of securities sold by us pursuant to General Instruction I.B.6 of Form S-3 during the twelve-month period immediately prior to, and including, the date of any such sale, does not exceed one-third of the

17

aggregate market value of our common stock held by non-affiliates (as determined by General Instruction I.B.6 of Form S-3), and we will remain subject to such limitation for so long as the aggregate market value of our common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3). As of the date of filing of this Quarterly Report on Form 10-Q, we have reached this limit and, as such, may not sell any additional securities under the ATM Facility (or otherwise under Form S-3) until such time as (i) during the preceding twelve-month period, we have not sold securities in excess of the limitation set forth in General Instruction I.B.6 of Form S-3, or (ii) the aggregate market value of our common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3).

We are not obligated to sell any shares under the ATM Facility. The ATM Facility may be terminated at any time upon ten days’ prior notice, or at any time in certain circumstances, including the occurrence of a material adverse effect on us. We agreed to pay the sales agent a commission equal to 3.0% of the gross proceeds from the sales of shares under the ATM Facility and have agreed to provide the sales agent with customary indemnification and contribution rights. We issued 6.1 million shares of common stock for gross proceeds of approximately $7.7 million under the ATM Facility from July 1, 2022 through December 31, 2022 and incurred $595,000 in issuance costs related to the ATM Facility and shelf registration statement.

Future Capital Requirements

We have not generated any revenue from product sales or from out-licensing. We do not know when, or if, we will generate any revenue. We expect to incur ongoing losses as we develop our current lead product candidate, FB-102, which has potentially broad application for autoimmune diseases such as alopecia areata, graft-vs-host disease and vitiligo. FB-102 is in preclinical development. Our future capital requirements are difficult to forecast and will depend on many factors, including but not limited to:

If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Any future debt financing may impose upon us covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and engage in certain merger, consolidation or asset sale transactions. Any equity or debt financing may contain terms that are not favorable to us or our stockholders. In addition, our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the COVID‑19 pandemic, the conflicts in Eastern Europe, recent and any potential future financial institution failures, and otherwise. If we are unable to raise additional funds when needed, we may be required to delay, reduce or terminate some or all of our development programs and clinical trials. We may also be required to sell or license to other parties rights to develop or commercialize our drug candidates that we would prefer to retain.

See the “Risk Factors” section on this Form 10-Q for additional risks associated with our substantial capital requirements.

The following table shows a summary of our cash flows for the three months ended March 31, 2023 and 2022 (in thousands):

Operating Activities

Net cash used in operating activities for the three months ended March 31, 2023 was $5.2 million and consisted primarily of a net loss of $6.8 million adjusted for non-cash stock-based compensation of $0.9 million and decreases in net operating assets of $0.7 million.

Net cash used in operating activities for the three months ended March 31, 2022 was $2.0 million and consisted primarily of a net loss of $2.6 million adjusted for non-cash stock-based compensation of $1.1 million and increases in net operating assets of $0.5 million.

Financing Activities

Net cash provided by financing activities for the three months ended March 31, 2023 was primarily due to the issuance of shares of our common stock under the ESPP.

Net cash used in financing activities of $34,000 for the three months ended March 31, 2022 was primarily due to payment of $46,000 for deferred financing costs, offset by $12,000 received from issuance of our common stock under the ESPP and for the exercise of stock options.

Off-Balance Sheet Arrangements

We have not entered into any off-balance sheet arrangements and do not have any holdings in variable interest entities.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Qualitative and Quantitative Disclosures About Market Risk

We are a smaller reporting company as defined by Rule 12b‑2 of the Securities Exchange Act of 1934, as amended, or the Exchange Act, and are not required to provide the information required under this item.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act, as of the end of the period covered by this quarterly report on Form 10-Q. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable and not absolute assurance of achieving the desired control objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were not effective at the reasonable assurance level due to a material weakness in our internal control over the review of our annual income tax provision, as discussed in more detail in Part II, Item 9A of the Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

Notwithstanding the identified material weakness described above, our Chief Executive Officer and our Chief Financial Officer believe the consolidated financial statements included in this Quarterly Report on Form 10-Q fairly represent in all material respects our financial condition, results of operations and cash flows at and for the periods presented in accordance with U.S. GAAP.

Material Weakness Remediation

We are taking steps to remediate the material weakness mentioned above, including, augmenting third-party resources tasked with tax accounting review, strengthening our review process related to our tax provision and implementing additional procedures to ensure appropriate review of such matters. However, we are still in the process of implementing these steps and cannot assure investors that these measures will significantly improve or remediate the material weakness described above.

Changes in Internal Control over Financial Reporting

Except with respect to the changes in connection with the implementation of the steps to remediate the material weakness described above, there has been no change in our internal control over financial reporting during the quarter ended March 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

20

Part II. OTHER INFORMATION

Item 1: Legal Proceedings

In November 2022, a stockholder of the Company filed a complaint in the Delaware Court of Chancery to access certain books and records of the Company pursuant to Section 220 of the Delaware General Corporation Law, as well as to seek attorney fees (the “Books and Records Action”). The Books and Records Action remains pending. The Company believes that it has meritorious defenses to the claims asserted in the Books and Records Action and intends to vigorously defend against it and may be entitled to attorney fees should the stockholder not determine to dismiss the action.

Item 1A: Risk Factors

You should consider carefully the following information about the risks described below, together with the other information contained in this Quarterly Report on Form 10-Q and in our other public filings, in evaluating our business. If any of the following risks actually occurs, our business, financial condition, results of operations, and future growth prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock would likely decline.

Our ability to execute on our business strategy is subject to a number of risks, which are discussed more fully below in this section. You should carefully consider these risks before making an investment in our common stock. These risks include, among others, the following:

Risks related to Forte’s business, technology and industry

Forte’s business through to 2021 had been almost entirely dependent on the success of FB-401 and Forte subsequently decided to discontinue the advancement of FB-401. In 2022, Forte decided to devote significant time and resources to developing FB-102, which may not be successful.

Through 2021, Forte invested substantially all of its efforts and financial resources into the research and development of FB-401, which was its only product candidate to enter clinical trials. In September 2021, Forte announced that it would not be continuing the advancement of FB-401.

Following the announcement of the FB-401 trial results, the Company ceased further development of FB-401 and conducted an extensive process to evaluate strategic alternatives. Following such process, the Company determined to focus on developing its FB-102 program, which is currently in preclinical development. We will be required to devote significant time and resources to developing FB-102, which may not be successful.

Results from early-preclinical studies may not be predictive of results from later-stage studies or clinical trials.

We are early in our testing of FB-102, and we have no product candidates in clinical development. Preclinical studies may produce negative or inconclusive results. The FDA or a non-US regulatory authority may require us to conduct additional preclinical testing. Success in early preclinical studies does not mean that future clinical trials will be successful. In addition, preclinical data are often susceptible to various interpretations and analyses, and many companies whose product candidates performed satisfactorily in preclinical studies have nonetheless failed to obtain marketing approval. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in clinical trials, even after obtaining promising results in preclinical studies and early clinical trials. Any of these events could limit the commercial potential of our

22

product candidate and have a material adverse effect on our business, prospects, financial condition and results of operations.

Forte’s prospects are highly dependent on a single product candidate, FB-102, as we discontinued FB-401 in 2021. If we are unable to complete further development of, obtain approval for and commercialize FB-102 for one or more indications in a timely manner, our business will be harmed.

After we discontinued clinical development of FB-401, Forte’s long-term prospects are highly dependent on future acceptance and revenues from a single product, FB-102. As discussed above, in September 2021, Forte announced that topline data from its Phase 2 clinical trial of FB-401 for the treatment of atopic dermatitis failed to meet statistical significance for the primary endpoint of EASI-50 (the proportion of patients with at least a 50% improvement in atopic dermatitis disease severity as measured by EASI) and that, given that result, Forte would not be continuing development of FB-401. Our prospects are thus highly dependent on the success of FB-102, our only product candidate at this time, which is currently in preclinical stage and is being evaluated for multiple indications. Any further development of FB-102 would require substantial capital and time to complete and there is no guarantee that any future clinical trial, if pursued, would be timely or successful, or that FB-102 would be approved or, if approved, that commercialization would be successful.

Forte has no approved products and has a limited operating history, which may make it difficult to evaluate its technology and product development capabilities and predict its future performance.

We are very early in our development efforts of FB-102 and, prior to discontinuing the advancement of FB-401, were early in our clinical development efforts of FB-401.

Prior to the closing of the reverse merger (“Merger”) with Tocagen, Inc. on June 15, 2020, Forte’s predecessor company was formed in 2017 as a privately held company. Forte has no products approved for commercial sale and has not generated any revenue from product sales. Forte’s ability to generate product revenue or profits was dependent on the successful development and eventual commercialization of FB-401 prior to Forte’s decision to discontinue development of FB-401 and, following Forte’s decision to focus on development of FB-102, Forte’s prospects are currently highly dependent on Forte’s ability to successfully develop FB-102. Given the early stage of FB-102, which is currently in preclinical development, and the highly uncertain nature of preclinical drug development, Forte may never be able to develop or commercialize a marketable product.

Forte’s current and future programs and product candidates will require additional discovery research, preclinical development, clinical development, regulatory approval to commercialize the product, manufacturing validation, obtaining manufacturing supply, capacity and expertise, building of a commercial and distribution organization, substantial investment and significant marketing efforts before Forte generates any revenue from product sales. In addition, any drug product candidate must be approved for marketing by the FDA or certain other health regulatory agencies before Forte may commercialize any product in the respective jurisdictions.

Forte’s limited operating history may make it difficult to evaluate its, or any new, technology and industry and predict its future performance. Forte’s short history as an operating company makes any assessment of its future success or viability subject to significant uncertainty. Forte will encounter risks and difficulties frequently experienced by early-stage companies in evolving fields, for example the failure of the FB-401 trial. If Forte does not address these risks successfully, its business will suffer. Similarly, Forte expects that its financial condition and operating results will fluctuate significantly from quarter to quarter and year to year due to a variety of factors, many of which are beyond its control. As a result, its stockholders should not rely upon the results of any quarterly or annual period as an indicator of future operating performance.

Forte has incurred net losses in every year since its inception and anticipates that it will continue to incur net losses in the future.

Forte is a preclinical stage healthcare company with a limited operating history. Investment in product development in the healthcare industry, including of biopharmaceutical products, is highly speculative because it

23

entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate effect or an acceptable safety profile, gain regulatory approval and become commercially viable. Forte’s current lead product candidate, FB-102, is currently in preclinical development. Forte has no products approved for commercial sale and has not generated any revenue from product sales to date, and Forte will continue to incur significant research and development and other expenses related to its ongoing operations. As a result, Forte is not profitable and has incurred losses in each period since its inception in 2017. For the three months ended March 31, 2023, Forte reported a net loss of $6.8 million. As of March 31, 2023, Forte had an accumulated deficit of $93.8 million. Forte expects to continue to incur significant losses for the foreseeable future, and Forte expects these losses to increase as Forte continues its research and development of, and seeks regulatory approvals for, its current lead product candidate, FB-102, and any future product candidates Forte may seek to develop. Forte anticipates that its expenses will increase substantially if, and as, it:

To become and remain profitable, Forte or any potential future collaborator must develop and eventually commercialize products with significant market potential at an adequate profit margin after cost of goods sold and other expenses. This will require Forte to be successful in a range of challenging activities, including completing preclinical studies and clinical trials, obtaining marketing approval for FB-102 or any future product candidates, manufacturing, marketing and selling products for which Forte may obtain marketing approval and satisfying any post-marketing requirements. Forte may never succeed in any or all of these activities and, even if Forte does, Forte may never generate revenue that is significant enough to achieve profitability. If Forte does achieve profitability, it may not be able to sustain or increase profitability on a quarterly or annual basis. Forte’s failure to become and remain profitable would decrease the value of the company and could impair its ability to raise capital, maintain its research and development efforts, expand its business or continue its operations.

Even if Forte succeeds in obtaining regulatory approval and commercializing its current product candidate, FB-102, Forte may continue to incur substantial research and development and other expenditures to develop and market additional applications for its current product candidate or any future product candidates. Forte may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect its business. The size of its future net losses will depend, in part, on the rate of future growth of its expenses and its ability to generate revenue. Forte’s prior losses and expected future losses have had and will continue to have an adverse effect on its stockholders’ equity and working capital.

24

Forte will require additional capital to fund its operations and if Forte fails to obtain necessary financing, Forte will not be able to complete the development and commercialization of its current lead product candidate, FB-102, or any future product candidates.

Forte’s operations have consumed substantial amounts of cash since inception. Forte expects to continue to spend substantial amounts to conduct preclinical studies and clinical trials of its current and future programs, to validate the manufacturing process and specifications for its product candidate, to seek regulatory approvals for its product candidate and to launch and commercialize any products for which Forte receives regulatory approval, including potentially building its own commercial organization. As of March 31, 2023, Forte had approximately $35.9 million of cash and cash equivalents on hand. Based on its current operating plan, Forte believes that its current cash available will enable it to fund its operating expenses and capital expenditure requirements through at least twelve months from the issuance date of this Form 10-Q. However, its future capital requirements and the period for which its existing resources will support its operations may vary significantly from what Forte currently expects, and Forte will in any event require additional capital in order to complete the clinical development of FB-102. Forte’s monthly spending levels will vary based on new and ongoing development and corporate activities. Because the length of time and activities associated with development of FB-102 and any future product candidates is highly uncertain, Forte is unable to estimate the actual funds it will require for development and any approved marketing and commercialization activities. Forte’s future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

25

In June 2021, Forte filed a shelf registration statement on Form S-3 that went effective in June 2021 which will allow Forte to raise up to $300 million in additional capital. On March 31, 2022, Forte entered into an “at-the-market” equity offering program (“ATM Facility”) whereby Forte may from time to time offer and sell shares of its common stock up to an aggregate offering price of $25.0 million during the term of the ATM Facility. On April 1, 2022, Forte filed a prospectus supplement to the June 2021 Form S-3 for the offer and sale of the shares under the ATM Facility covering sales of up to $7.0 million of shares of common stock. On August 12, 2022, Forte filed an additional prospectus supplement relating to offer and sell an additional $2.7 million of shares of common stock. Forte is currently eligible to sell securities under Form S-3 only if and to the extent the aggregate market value of securities sold by Forte pursuant to General Instruction I.B.6 of Form S-3 during the twelve-month period immediately prior to, and including, the date of any such sale, does not exceed one-third of the aggregate market value of Forte’s common stock held by non-affiliates (as determined by General Instruction I.B.6 of Form S-3), and Forte will remain subject to such limitation for so long as the aggregate market value of Forte’s common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3). As of the date of filing of this Quarterly Report on Form 10-Q, Forte has reached this limit and, as such, may not sell any additional securities under the ATM Facility (or otherwise under Form S-3) until such time as (i) during the preceding twelve-month period, we have not sold securities in excess of the limitation set forth in General Instruction I.B.6 of Form S-3, or (ii) the aggregate market value of our common stock held by non-affiliates is less than $75 million (as determined by General Instruction I.B.6 of Form S-3). As such, while the ATM Facility remains in place, it is not currently a source of additional funding for Forte and Forte remains restricted in its ability to access additional funding from the sale of securities under Form S-3.

Forte does not have any committed external source of funds or other support for its development efforts, and Forte cannot be certain that additional funding will be available on acceptable terms, or at all. Until Forte can generate sufficient product or royalty revenue to finance its cash requirements, which Forte may never do, Forte expects to finance its future cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic alliances, licensing arrangements and other marketing or distribution arrangements. If Forte raises additional funds through public or private equity offerings, the terms of these securities may include liquidation or other preferences that adversely affect its stockholders’ rights. Further, to the extent that Forte raises additional capital through the sale of common stock or securities convertible into or exchangeable for common stock, each existing investors’ ownership interest will be diluted. If Forte raises additional capital through debt financing, Forte would be subject to fixed payment obligations and may be subject to covenants limiting or restricting its ability to take specific actions, such as incurring additional debt, making capital expenditures, declaring dividends or acquiring or licensing intellectual property rights. If Forte raises additional capital through

26

marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, Forte may have to relinquish certain valuable rights to its product candidate, technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to it. Forte also could be required to seek collaborators for one or more of its current or future product candidates at an earlier stage than otherwise would be desirable or relinquish its rights to product candidates or technologies that Forte otherwise would seek to develop or commercialize itself. In addition, our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the COVID‑19 pandemic, the conflicts in Eastern Europe, the effect of inflationary pressure on the United States capital markets, adverse developments affecting the financial services industry (such as the closure of Silicon Valley Bank in March 2023 and any similar bank closures) and otherwise. If Forte is unable to raise additional capital in sufficient amounts or on terms acceptable to it, Forte may have to significantly delay, scale back or discontinue the development or commercialization of its current product candidate, FB-102, or one or more of its other current or future research and development initiatives. Any of the above events could significantly harm its business, prospects, financial condition and results of operations and cause the price of its common stock to decline.

Forte’s ability to successfully develop any product candidate is highly uncertain.

Forte’s ability to successfully develop FB-102 or any other future product candidate is highly uncertain and is dependent on numerous factors, many of which are beyond Forte’s control. Product candidates that appear promising in the early phases of development may fail to reach the market for several reasons, including:

The length of time necessary to complete clinical trials and to submit an application for marketing approval of a drug product candidate for a final decision by a regulatory authority may be difficult to predict for FB-102 or any future product candidate, in large part because of its limited regulatory history.

Even if Forte is successful in obtaining market approval for a drug product, commercial success of any approved products will also depend in large part on marketing acceptance, the availability of insurance coverage and adequate reimbursement from third-party payors, including government payors, such as the Medicare and Medicaid programs, and managed care organizations, which may be affected by existing and future healthcare reform measures designed to reduce the cost of healthcare. For example, in August 2022, Congress passed the Inflation Reduction Act of 2022, which includes prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal government to negotiate a maximum fair price for certain high-priced single source Medicare drugs, imposing penalties and excise tax for manufacturers that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited exceptions, if their drug prices increase faster than inflation, and

27

redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for beneficiaries, among other changes. The impact of these legislative, executive, and administrative actions and any future healthcare measures and agency rules implemented by the Biden administration on us and the pharmaceutical industry as a whole is unclear. Any reduction in reimbursement from Medicare or other government programs may result in a reduction in payments from private payors. Third-party payors could require Forte to conduct additional studies, including post-marketing studies related to the cost-effectiveness of the product, to qualify for reimbursement, which could be costly and divert its resources. If government and other healthcare payors were not to provide adequate insurance coverage and reimbursement levels for any of its drug products once approved, market acceptance and commercial success would be reduced.

In addition, if any of Forte’s drug product candidates, including FB-102, are approved for marketing, Forte will be subject to significant regulatory obligations regarding the submission of safety and other post-marketing information and reports and registration. If approved, any of its drug products would be subject to restrictions on its products’ labels and other conditions of regulatory approval that may limit its ability to market its products. Forte will also need to comply (and ensure that its third-party contractors comply) with cGMPs, and Good Clinical Practice (“GCP”), as Forte (and its third-party contractors) will be required to comply with these requirements for the products or product candidates used in its clinical trials or post-approval studies. In addition, Forte will need to comply with GCPs for any clinical trial conducted for any therapeutic indications Forte may develop for approval. In addition, there is always the risk that Forte or a regulatory authority might identify previously unknown problems with a drug product post-approval, such as adverse events of unanticipated severity or frequency. Compliance with these requirements and other regulatory requirements is costly and any failure to comply or other issues with its product post-approval could have a material adverse effect on its business, financial condition and results of operations.

Clinical development is a lengthy and expensive process, with an uncertain outcome. Forte may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of any product candidate.

To obtain the requisite regulatory approvals to commercialize any product candidate, Forte must demonstrate through extensive clinical trials that its product candidate is safe and effective in humans for its intended use. Clinical testing is expensive, difficult to design and implement and can take many years to complete, and its outcome is inherently uncertain. As seen with the FB-401 trial, Forte may be unable to establish clinical endpoints, dose levels and regimens or bioanalytical assay methods that applicable regulatory authorities would consider clinically meaningful, and a clinical trial can fail at any stage of testing. The outcome of preclinical studies and early clinical trials may not be predictive of the success of later clinical trials, and interim results of these studies or trials do not necessarily predict final results. Differences in trial design between early-stage clinical trials and later-stage clinical trials make it difficult to extrapolate the results of earlier clinical trials to later clinical trials. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidate performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their product candidate.

Successful completion of clinical trials is a prerequisite to submitting a BLA to the FDA, and similar marketing applications to comparable foreign regulatory authorities, for each product candidate, and, consequently, the ultimate approval and commercial marketing of any product candidate.

28

Forte may experience delays in initiating or completing any future clinical trials. Forte also may experience numerous unforeseen events during, or as a result of, any future clinical trials that Forte could conduct that could delay or prevent its ability to receive marketing approval or commercialize its product candidate, including:

29

Forte could also encounter delays if a clinical trial is suspended or terminated for any reason. A suspension or termination may be imposed due to a number of factors, including failure to conduct the clinical trial in accordance with regulatory requirements or its clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a product or treatment, failure to establish or achieve clinically meaningful trial endpoints, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of its product candidate. Further, the FDA or other regulatory authorities may disagree with its clinical trial design and its interpretation of data from clinical trials or may change the requirements for approval even after they have reviewed and commented on the design for its clinical trials.

Forte’s product development costs will increase if it experiences delays in clinical testing or marketing approvals. Forte does not know whether any of its clinical trials will begin as planned, will need to be restructured or will be completed on schedule, or at all. Significant clinical trial delays also could shorten any periods during which Forte may have the exclusive right to commercialize its product candidate and may allow its competitors to bring products to market before Forte does, potentially impairing its ability to successfully commercialize its product candidate upon approval and harming its business and results of operations. Any delays in its future clinical development programs may harm its business, financial condition and prospects significantly.

Forte’s planned preclinical studies or future clinical trials or those of its future collaborators may reveal significant adverse events and may result in a safety profile that could inhibit regulatory approval or market acceptance of any of its product candidates.

Before obtaining regulatory approvals for the commercial sale of any products, Forte must demonstrate through lengthy, complex and expensive preclinical studies and clinical trials that FB-102 is both safe and effective for use in each target indication. Preclinical and clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the preclinical or clinical trial process. The results of preclinical studies as well as early clinical trials of a product candidate may not be predictive of the results of later-stage clinical trials. In addition, initial success in clinical trials may not be indicative of results obtained when such clinical trials are completed. There is typically an extremely high rate of attrition from the failure of product candidate proceeding through clinical trials.

Forte’s FB-102 may fail to show the desired safety and efficacy profile. A number of companies in the healthcare industry have suffered significant setbacks in advanced clinical trials due to lack of efficacy and/or unacceptable safety issues, notwithstanding promising results in earlier preclinical studies or clinical trials. Most product candidates that commence clinical trials are never approved as products and there can be no assurance that any of its future clinical trials would be successful or support further clinical development of any product candidates.

30

If significant adverse events or other side effects are observed in any of its current or potential future preclinical studies or clinical trials, Forte may have difficulty recruiting patients to its clinical trials, patients may drop out of such trials or Forte may be required to significantly redesign or terminate trials or its development efforts of one or more product candidates altogether. Forte, the FDA, or other applicable regulatory authorities or an IRB may suspend or terminate clinical trials of a product candidate at any time for various reasons, including a belief that patients in such trials are being exposed to unacceptable health risks or adverse side effects. Some potential therapeutics developed in the healthcare industry that initially showed therapeutic promise in early-stage clinical trials have later been found to cause side effects that prevented their further development. Even if the side effects do not preclude the drug from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance of the approved product due to its tolerability versus other therapies. Any of these developments could materially harm Forte’s business, financial condition and prospects.

Positive results from early preclinical studies are not necessarily predictive of the results of any future clinical trials of product candidates. Forte may be unable to successfully develop, obtain regulatory approval for and commercialize any product candidates.

Any positive results from its preclinical studies and clinical trials of any product candidates may not necessarily be predictive of the results from required later clinical trials. Similarly, even if Forte is able to complete preclinical development and any future clinical trials of FB-102 or any other product candidates according to its current development timeline, the positive results from such preclinical studies or future clinical trials may not be replicated in subsequent clinical trial results.

Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical trials after achieving positive results in early-stage development, and Forte cannot be certain that it will not face similar setbacks. These setbacks have been caused by, among other things, preclinical findings, or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidate performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA or similar regulatory approval.

Interim top-line and preliminary data from future clinical trials that Forte announces or publishes from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, once Forte commences future clinical trials, Forte may publish interim top-line or preliminary data from its clinical trials. Interim data from these clinical trials that Forte may complete are subject to the risk that one or more of the outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary or top-line data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data Forte previously published. As a result, any such interim and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm its business prospects.

If Forte fails to comply with environmental, health and safety laws and regulations, Forte could become subject to significant fines or penalties or incur costs that could have a material adverse effect on the success of its business.

Forte is subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes, research and development activities involve the use of biological and hazardous materials and produce hazardous waste products. Forte generally contracts with third parties for the disposal of these materials and wastes. Forte cannot eliminate the risk of contamination or injury from these materials, which could cause an interruption of its commercialization efforts, research and development efforts and business operations, environmental damage resulting in costly clean-up and liabilities under applicable laws and regulations governing the use, storage, handling

31

and disposal of these materials and specified waste products. Although Forte believes that the safety procedures utilized by its third-party manufacturers for handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, Forte cannot guarantee that this is the case or eliminate the risk of accidental contamination or injury from these materials. In such an event, Forte may be held liable for any resulting damages and such liability could exceed its resources and state or federal or other applicable authorities may curtail its use of certain materials and/or interrupt its business operations. Furthermore, environmental laws and regulations are complex, change frequently and have tended to become more stringent. Forte cannot predict the impact of such changes and cannot be certain of its future compliance. In addition, Forte may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair its research, development or production efforts. Failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

Although Forte maintain workers’ compensation insurance to cover it for costs and expenses Forte may incur due to injuries to its employees resulting from the use of biological waste or hazardous materials or other work-related injuries, this insurance may not provide adequate coverage against potential liabilities. Forte does not carry specific biological waste or hazardous waste insurance coverage, workers compensation or property and casualty and general liability insurance policies that include coverage for damages and fines arising from biological or hazardous waste exposure or contamination.

The market opportunities for FB-102 may be limited and Forte’s estimates of the incidence and prevalence of its target patient populations may be inaccurate.

Forte’s projections of both the number of people who have the diseases Forte is targeting, as well as the subset of people with these diseases in a position to receive its therapies, if approved, are based on its beliefs and estimates. These estimates have been derived from a variety of sources, including scientific literature, input from key opinion leaders, patient foundations or secondary market research databases, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases or regulatory approvals may include limitations for use or contraindications that decrease the addressable patient population. The number of patients may turn out to be lower than expected. Additionally, the potentially addressable patient population for its product candidate may be limited or may not be amenable to treatment with its product candidate. Even if Forte obtains significant market share for its product candidate, because certain of the potential target populations are small, Forte may never achieve profitability without obtaining regulatory approval for additional indications.

Forte faces significant competition from other healthcare companies, and its operating results will suffer if Forte fails to compete effectively.

The healthcare industry is characterized by intense competition and rapid innovation. Forte’s competitors may be able to develop other compounds or products that are able to achieve similar or better results. Forte’s potential competitors include major multinational pharmaceutical, established biotechnology companies, specialty pharmaceutical companies and universities and other research institutions. Many of its competitors have substantially greater financial, technical and other resources, such as larger research and development staff, experienced marketing and manufacturing organizations and well-established sales forces. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large, established companies. Established pharmaceutical companies may also invest heavily to accelerate discovery and development of novel therapeutics or to in-license novel therapeutics that could make any product candidate that Forte develops obsolete. Mergers and acquisitions in the healthcare industry may result in even more resources being concentrated amongst its competitors. Competition may increase further as a result of advances in the commercial applicability of technologies and greater availability of capital for investment in these industries. Forte’s competitors, either alone or with collaborative partners, may succeed in developing, acquiring or licensing therapies that are more effective, safer, more easily commercialized or less costly than FB-102 or may develop proprietary technologies or secure patent protection that Forte may need for the development of potential technologies and products. Forte believes the key competitive factors that will affect the development and commercial success of its

32

product candidate are efficacy, safety, tolerability, reliability, convenience of use, compliance with regulatory requirements, acceptance by patients or prescribers, competitive pricing and reimbursement.

Forte anticipates competing with the largest healthcare companies in the world, many of which have greater financial, human, and manufacturing resources than Forte currently has. In addition to these fully integrated healthcare companies, Forte will also compete with those companies whose products target the same indications as FB-102 or any future product candidate Forte develops. They include pharmaceutical companies, biotechnology companies, academic institutions and other research organizations. Any treatments developed by its competitors could be superior to any product candidates Forte develops. It is possible that these competitors will succeed in developing technologies that are more effective than Forte’s potential products or that would render any of Forte’s product candidate obsolete or noncompetitive. Forte anticipates that it will face increased competition in the future as additional companies enter its market and scientific developments surrounding competing therapies continue to accelerate.

Even if FB-102 or any other product candidate that Forte develops receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors, consumers and others in the medical or healthcare community necessary for commercial success.

If FB-102 or any other future product candidate Forte develops receives marketing approval, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors, consumers and others in the medical community. If any such product candidate Forte develops does not achieve an adequate level of acceptance, Forte may not generate significant product revenues and Forte may not become profitable. The degree of market acceptance of any of Forte’s product candidates, if approved for commercial sale, will depend on a number of factors, including:

Forte’s operations and financial results could be adversely impacted by the 2019 Novel Coronavirus (COVID-19) or other pandemics.

While the extent of the impact of the COVID-19 pandemic on Forte’s business and financial results is uncertain, including indirect impact via third parties Forte contracts with, a continued and prolonged public health crisis could have a negative impact on its business, financial condition and operating results. Due to the global pandemic impacting the United States, its preclinical studies could also be slowed or delayed, or in a more severe scenario, its business, financial condition and operating results could be more severely affected. While the World Health Organization has determined that COVID-19 no longer represents a global health emergency, given the dynamic nature of these circumstances, the duration of any business disruption or potential impact to Forte’s business as a result of the COVID-19 pandemic is difficult to predict, which may increase its costs or expenses. In April 2023, President Biden signed legislation that will end the COVID-19 national emergency on May 11, 2023.

33

The full impact of this termination of the national emergency and the wind-down of the public health emergency on FDA and other regulatory policies and operations are unclear.

Forte will need to grow the size of its organization, and may experience difficulties in managing this growth.

As of May 11, 2023, Forte had 7 full-time employees. As its research, development, manufacturing and commercialization plans and strategies develop to focus on the development of FB-102 and any future product candidates, and as Forte continues to transition into operating as a public company, Forte expects to need additional managerial, operational, sales, marketing, financial and other personnel. Future growth would impose significant added responsibilities on members of management, including:

Forte’s future financial performance and its ability to commercialize FB-102 or any future product candidate will depend, in part, on its ability to effectively manage any future growth, and its management may also have to divert a disproportionate amount of its attention away from day-to-day activities in order to devote a substantial amount of time to managing these growth activities.

Forte currently relies, and for the foreseeable future will continue to rely, in substantial part on certain organizations, advisors and consultants to provide certain services, including many aspects of regulatory affairs, clinical management and manufacturing. There can be no assurance that the services of these organizations, advisors and consultants will continue to be available to Forte on a timely basis when needed or that Forte can find qualified replacements. In addition, if Forte is unable to effectively manage its outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, its preclinical studies and clinical trials may be extended, delayed or terminated, and Forte may not be able to obtain regulatory approval of FB-102 or any other future product candidate or otherwise advance its business. There can be no assurance that Forte will be able to manage its existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all.

If Forte is not able to effectively expand its organization by hiring new employees and expanding its groups of consultants and contractors, Forte may not be able to successfully implement the tasks necessary to further develop and commercialize any product candidate and, accordingly, may not achieve its research, development and commercialization goals.

Forte’s current operations are located in Texas, and Forte or the third parties upon whom Forte depends may be adversely affected by natural disasters or the COVID-19 outbreak or other pandemics, and its business continuity and disaster recovery plans may not adequately protect Forte from a serious disaster.

Forte’s current operations are located in Texas. Any unplanned event, such as flood, fire, tornado, explosion, earthquake, extreme weather condition, medical epidemics, such as the COVID-19 outbreak, power shortage, telecommunication failure or other natural or manmade accidents or incidents that result in it being unable to fully utilize its facilities, or the manufacturing facilities of its third-party contract manufacturers, may have a material and adverse effect on its ability to operate its business, particularly on a daily basis, and have significant negative consequences on its financial and operating conditions. Loss of access to these facilities may result in increased costs, delays in the development of its product candidate or interruption of its business operations. Any natural disasters could further disrupt its operations and have a material and adverse effect on its business, financial condition, results of operations and prospects. If a natural disaster, power outage or other event occurred that prevented it from using all or a significant portion of its headquarters, that damaged critical infrastructure, such as its research facilities or the manufacturing facilities of its third-party contract manufacturers, or that otherwise disrupted

34

operations, it may be difficult or, in certain cases, impossible, for Forte to continue its business for a substantial period of time. As part of its risk management policy, Forte maintains insurance coverage at levels that Forte believes are appropriate for its business. However, in the event of an accident or incident at these facilities, Forte cannot assure you that the amounts of insurance will be sufficient to satisfy any damages and losses. If its facilities, or the manufacturing facilities of its third-party contract manufacturers, are unable to operate because of an accident or incident or for any other reason, even for a short period of time, any or all of its research and development programs may be harmed. Any business interruption may have a material and adverse effect on its business, financial condition, results of operations and prospects.

If Forte loses key management personnel, or if Forte fails to recruit additional highly skilled personnel, its ability to identify and develop new or next generation product candidate will be impaired, could result in loss of markets or market share and could make Forte less competitive.

Forte’s ability to compete in the highly competitive healthcare industry depends upon its ability to attract and retain highly qualified managerial, scientific and medical personnel. Forte is highly dependent on its management, scientific and medical personnel, including Paul Wagner, Ph.D. The loss of the services of any of its executive officers, other key employees, and other scientific and medical advisors, and its inability to find suitable replacements could result in delays in product development and harm its business.

To retain valuable employees in a competitive market, in addition to salary and cash incentives, Forte has provided stock options that vest over time. The value to employees of equity awards that vest over time may be significantly affected by decreases in our stock price that are beyond our control and may at any time be insufficient to counteract more lucrative offers from other companies. We may face challenges in retaining and recruiting such individuals due to sustained declines in our stock price that could reduce the retention value of equity awards. Despite its efforts to retain valuable employees, members of its management, scientific and development teams may terminate their employment with Forte on short notice. Employment of its key employees is at-will, which means that any of its employees could leave its employment at any time, with or without notice. Forte does not maintain “key man” insurance policies on the lives of these individuals or the lives of any of its other employees. Forte’s success also depends on its ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers as well as junior, mid-level and senior scientific and medical personnel.

Forte’s internal computer systems, or those used by its CROs, CMOs or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, Forte’s internal computer systems and those of its future CROs, CMOs and other contractors and consultants are vulnerable to damage from computer viruses and unauthorized access. While Forte has not experienced any such material system failure or security breach to date, if such an event were to occur and cause interruptions in its operations, it could result in a material disruption of its development programs and its business operations. To the extent that any disruption or security breach were to result in a loss of, or damage to, its data or applications, or inappropriate disclosure of confidential or proprietary information, Forte could incur liability and the further development and commercialization of product candidates could be delayed.

Regulators globally are also imposing greater monetary fines for privacy violations. For example, in 2016, the European Union adopted the GDPR, which became effective on May 25, 2018. The GDPR applies to any company that collects and uses personal data in connection with offering goods or services to individuals in the European Union or the monitoring of their behavior. Non-compliance with the GDPR may result in monetary penalties of up to €20 million or 4% of worldwide revenue, whichever is higher. The GDPR and other changes in laws or regulations associated with the enhanced protection of certain types of personal data, such as healthcare data or other sensitive information, could greatly increase the cost of providing its product candidate, if approved, or even prevent Forte from offering any product candidate, if approved, in certain jurisdictions.

35

Forte’s employees, independent contractors, consultants, commercial partners and vendors acting on its behalf may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

Forte is exposed to the risks of employee fraud or other illegal activity by its employees, independent contractors, consultants, commercial partners and vendors acting on its behalf. Misconduct by these parties could include intentional, reckless and/or negligent conduct that fails to comply with the laws of the FDA and other similar foreign regulatory bodies, provide true, complete and accurate information to the FDA and other similar foreign regulatory bodies, comply with manufacturing standards Forte has established, comply with healthcare fraud and abuse laws in the United States and similar foreign fraudulent misconduct laws or report financial information or data accurately or to disclose unauthorized activities to us. If Forte obtains FDA approval of any product candidate and begin commercializing such product in the United States, its potential exposure under such laws will increase significantly, and its costs associated with compliance with such laws are also likely to increase. These laws may impact, among other things, its current activities with principal investigators and research patients, as well as proposed and future sales, marketing and education programs.

Manufacturers of biopharmaceutical products and their facilities, vendors and suppliers are subject to continual review and periodic unannounced inspections by the FDA and other regulatory authorities for compliance with cGMP regulations, which include requirements relating to quality control and quality assurance as well as to the corresponding maintenance of records and documentation. Furthermore, its manufacturing facilities must be approved by regulatory agencies before these facilities can be used to manufacture its products or product candidates, and they will also be subject to additional regulatory inspections. Any material changes Forte may make to its manufacturing process or to the components used in its products may require additional prior approval by the FDA and state or foreign regulatory authorities. Failure to comply with FDA or other applicable regulatory requirements may result in criminal prosecution, civil penalties, recall or seizure of products, partial or total suspension of production or withdrawal of a product from the market.

A variety of risks associated with testing and developing a product candidate internationally could materially adversely affect Forte’s business.

Forte may seek regulatory approval of its product candidate outside of the United States and, if so, Forte expects that it will be subject to additional risks related to operating in foreign countries if Forte obtains the necessary approvals, including:

36

These and other risks associated with its international operations may materially adversely affect its ability to attain or maintain profitable operations. Obtaining and maintaining regulatory approval of a product candidate in one jurisdiction does not guarantee that Forte will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the product, manufacturing, and in many cases reimbursement of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies or clinical trials as clinical studies conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In some cases, the price that Forte intends to charge for its products is also subject to approval by regulatory authorities. If Forte fails to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, its target market will be reduced and its ability to realize the full market potential of a product candidate will be harmed.

Forte currently has no marketing and sales organization and has no experience in marketing products. If Forte is unable to establish marketing and sales capabilities or enter into agreements with third parties to market and sell its product candidate, Forte may not be able to generate product revenue.

Forte currently has no sales, marketing or distribution capabilities and has no experience in marketing products. If and when Forte reaches the commercialization stage, Forte intends to develop an in-house marketing organization and sales force, which will require significant capital expenditures, management resources and time. Forte will have to compete with other healthcare companies to recruit, hire, train and retain marketing and sales personnel.

There can be no assurance that Forte would be able to develop in-house sales and distribution capabilities or establish or maintain relationships with third-party collaborators to commercialize any product in the United States or overseas.

Comprehensive tax reform legislation could adversely affect Forte’s business and financial condition.

Recent changes to U.S. tax laws, as well as changes to U.S. tax laws that may be enacted in the future, could impact the tax treatment of Forte’s business and financial condition. For example, on December 22, 2017, former President Trump signed into law the Tax Act, that significantly reforms the Code. The Tax Act, among other things, contains significant changes to corporate taxation, including changes to U.S. federal tax rates, limitation of the tax deduction for interest expense, and the modification and repeal of many business deductions and credits (including the reduction of the business tax credit for certain clinical testing expenses incurred in the testing of certain drugs for rare diseases or conditions generally referred to as “orphan drugs”). The new presidential administration and Congress could make changes to existing tax law, including an increase in the corporate and other tax rates. In addition, many countries in Europe, as well as a number of other countries and organizations, have recently considered changes to existing tax law that could adversely affect Forte’s financial condition and results of operations.

Forte’s ability to use net operating losses and research and development credits to offset future taxable income or tax liability may be subject to certain limitations.

As of December 31, 2022, Forte has federal net operating loss carryforwards of $24.9 million, which begin expiring in 2037 and state net operating loss carryforwards of $11.6 million that begin to expire in 2037, unless utilized. These NOL carryforwards could expire unused and be unavailable to offset future taxable income or tax liabilities, respectively. In addition, in general, under Sections 382, a corporation that undergoes an “ownership

37

change” is subject to limitations on its ability to utilize its pre-change NOLs to offset future taxable income or taxes. For these purposes, an ownership change generally occurs where the aggregate stock ownership of one or more stockholders or groups of stockholders who owns at least 5% of a corporation’s stock increases its ownership by more than 50 percentage points over its lowest ownership percentage within a specified testing period. Forte’s existing NOL carryforwards may be subject to limitations arising from previous ownership changes, and if Forte undergo an ownership change in connection with or after the Merger, its ability to utilize NOL carryforwards could be further limited by Section 382. In addition, future changes in its stock ownership, many of which are outside of its control, could result in an ownership change under Sections 382. Forte’s NOL carryforwards may also be impaired under state law. Accordingly, Forte may not be able to utilize a material portion of its NOL carryforwards. Furthermore, its ability to utilize its NOL carryforwards is conditioned upon its attaining profitability and generating U.S. federal and state taxable income. As described above, Forte has incurred significant net losses since its inception and anticipates that Forte will continue to incur significant losses for the foreseeable future; and therefore, Forte does not know whether or when Forte will generate the U.S. federal or state taxable income necessary to utilize its NOL carryforwards that are subject to limitation by Sections 382.

Unstable market and economic conditions, including adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults or non-performance by financial institutions or transactional counterparties, may have serious adverse consequences on Forte’s business, financial condition, results of operations, and stock price.

As widely reported, global credit and financial markets have experienced extreme volatility and disruptions in the past, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Forte’s general business strategy may be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, or do not improve, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on its growth strategy, financial performance and stock price and could require Forte to delay or abandon preclinical and clinical development plans. In addition, there is a risk that one or more of its current service providers, manufacturers and other partners may not survive these difficult economic times, which could directly affect its ability to attain its operating goals on schedule and on budget. Furthermore, its stock price may decline due in part to the volatility of the stock market and the general economic downturn.

In addition, actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, SVB was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation, or the FDIC, as receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership.

Although we assess our banking relationships as we believe necessary or appropriate, our access to funding sources and other credit arrangements in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial institutions with which we have arrangements directly, or the financial services industry or economy in general. These factors could include, among others, events such as liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets, or concerns or negative expectations about the prospects for companies in the financial services industry. These factors could involve financial institutions or financial services industry companies with which we have financial or business relationships, but could also include factors involving financial markets or the financial services industry generally.

38

In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all.

Risks related to government regulation

Forte is very early in its development efforts. FB-102 will require significant additional preclinical and clinical development before Forte seeks regulatory approval of any product candidate. If Forte is unable to advance FB-102 to clinical development, obtain regulatory approval and ultimately commercialize a product candidate or experiences significant delays in doing so, its business will be materially harmed.

Forte is very early in its development efforts and will invest substantially all of its efforts and financial resources in the development of FB-102. Its ability to generate product revenues, which Forte does not expect will occur for many years, if ever, will depend on the successful development and eventual commercialization of a product candidate, which may never occur. Forte currently generates no revenue from sales of any products, and Forte may never be able to develop or commercialize a marketable product. The success of FB-102 will depend on several factors, including the following:

If Forte does not achieve one or more of these factors in a timely manner or at all, Forte could experience significant delays or an inability to successfully commercialize FB-102, which would materially harm its business. If Forte does not receive regulatory approvals for FB-102, it may not be able to continue its operations.

Changes in the legal and regulatory environment could limit Forte’s future business activities, increase its operating or regulatory costs, reduce demand for product candidates or result in litigation.

The conduct of Forte’s business, including the development, testing, production, storage, distribution, sale, display, advertising, marketing, labeling, health and safety practices are subject to various laws and regulations administered by federal, state and local governmental agencies in the United States, as well as to laws and regulations administered by government entities and agencies outside the United States in markets in which its products candidates and components thereof (such as packaging) may be manufactured or sold.

39

These laws and regulations and interpretations thereof may change, sometimes dramatically, as a result of a variety of factors, including political, economic or social events. Such changes may include changes in:

New laws, regulations or governmental policy and their related interpretations, or changes in any of the foregoing, may alter the environment in which Forte does business and, therefore, may impact its operating results or increase its costs or liabilities.

Inadequate funding for the FDA, the SEC and other government agencies, or disruptions in their staffing levels related to the COVID-19 global pandemic, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the approval of Forte’s product candidates rely, which would negatively impact its business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which its operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect its business. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. In response to the COVID-19 public health emergency, since March 2020 when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been working to resume routine surveillance, bioresearch monitoring and pre-approval inspections on a prioritized basis. In 2020 and 2021, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. While the FDA has largely caught up with domestic preapproval inspections, it continues to work through its backlog of foreign inspections. However, the FDA may not be able to continue its current inspection pace, and review timelines could be extended, including where a pre-approval inspection or an inspection of clinical sites is required and due to the ongoing COVID-19 pandemic and travel restrictions, the FDA is unable to complete such required inspections during the review period. If a prolonged government shutdown or other disruption occurs, including due to travel restrictions, foreign COVID-19-related policies, staffing shortages, or if global health or other concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities in a timely manner, it could significantly impact the ability of the FDA to timely review and process its regulatory submissions, which could have a material adverse effect on its business, including its ability to access the public markets and obtain necessary capital in order to properly capitalize and continue its operations.

Forte’s relationships with healthcare providers, including physicians and clinical investigators, CROs, and third-party payors in connection with its current and future business activities may be subject to federal and state healthcare fraud and abuse laws, false claims laws, transparency laws, government price reporting, and health

40

information privacy and security laws, which could expose Forte to significant losses, including, among other things, criminal sanctions, civil penalties, contractual damages, reputational harm, exclusion from federal health care programs, administrative burdens, and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States and elsewhere play a primary role in the recommendation and prescription of pharmaceutical products. Arrangements with third-party payors and customers can expose pharmaceutical manufactures to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act, which may constrain the business or financial arrangements and relationships through which such companies sell, market and distribute pharmaceutical products. In particular, the research, promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials. The applicable federal, state and foreign healthcare laws and regulations laws that may affect Forte’s ability to operate include, but are not limited to:

41

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations or inquiries by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

The failure to comply with any of these laws or regulatory requirements subjects entities to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in civil, criminal and administrative penalties, damages, fines, disgorgement, individual imprisonment, possible exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of its operations, as well as additional reporting obligations and oversight if Forte becomes subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Any action for violation of these laws, even if successfully defended, could cause a pharmaceutical manufacturer to incur significant legal expenses and divert management’s attention from the operation of the

42

business. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect business in an adverse way.

Forte maintains a code of business conduct and ethics, but it is not always possible to identify and deter employee misconduct, and the precautions Forte takes to detect and prevent inappropriate conduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting Forte from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. Efforts to ensure that its business arrangements will comply with applicable healthcare laws may involve substantial costs. It is possible that governmental and enforcement authorities will conclude that its business practices may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and Forte is not successful in defending ourselves or asserting its rights, those actions could have a significant impact on its business, including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of its operations, any of which could adversely affect its ability to operate its business and its results of operations. In addition, the approval and commercialization of any of its product candidates outside the United States will also likely subject Forte to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Obtaining and maintaining regulatory approval of any of its product candidates in one jurisdiction does not mean that Forte will be successful in obtaining regulatory approval for its product candidate in other jurisdictions.

Obtaining and maintaining regulatory approval does not guarantee that Forte will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of a product candidate, comparable regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing and promotion of the product candidate in those countries. Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from, and greater than, those in the United States, including additional preclinical studies and clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in that jurisdiction. In some cases, the price that Forte intends to charge for its products may also be subject to approval.

Forte may also submit marketing applications in other countries. Regulatory authorities in jurisdictions outside of the United States have requirements for approval of a product candidate with which Forte must comply prior to marketing in those jurisdictions. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties and costs for Forte and could delay or prevent the introduction of its products in certain countries. If Forte fails to comply with the regulatory requirements in international markets and/or receive applicable marketing approvals, its target market will be reduced and its ability to realize the full market potential of its product candidate will be harmed.

Preclinical and clinical development is uncertain. Forte’s preclinical studies and clinical trials may experience delays or may never advance to the next stage of development, which would adversely affect its ability to obtain regulatory approvals to commercialize these programs on a timely basis or at all, which would have an adverse effect on its business.

To proceed with its development plans and ultimately commercialization of FB-102, Forte will be required to conduct preclinical studies and clinical trials. Forte cannot be certain of the timely completion or outcome of its preclinical testing and studies and cannot predict if the FDA or other regulatory authorities will accept its proposed clinical programs, including the design, dose level, and dose regimen, or if the outcome of its preclinical testing and studies will ultimately support the development of its clinical programs.

43

If Forte is not able to obtain, or if there are delays in obtaining, required regulatory approvals for any product candidates it may develop, Forte will not be able to commercialize, or will be delayed in commercializing, such product candidates, and its ability to generate revenue will be materially impaired.

Any product candidate Forte may develop and the activities associated with the development and commercialization of such product candidate, including its design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, distribution, import and export are subject to comprehensive regulation by the FDA and other regulatory agencies in the United States and by comparable authorities in other countries. Before Forte can commercialize any product candidate, Forte must obtain marketing approval. Forte has never received approval to market any product candidates from regulatory authorities in any jurisdiction and it is possible that no product candidates will ever obtain regulatory approval. Forte, as a company, has no experience in filing and supporting the applications necessary to gain regulatory approvals and expects to rely on third-party CROs and/or regulatory consultants to assist it in this process. Securing regulatory approval requires the submission of extensive preclinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the drug candidate’s safety, efficacy, purity, and potency.

Securing regulatory approval also requires the submission of information about the drug manufacturing process to, and inspection of manufacturing facilities by, the relevant regulatory authority. Any product candidate Forte develops may not be effective, may be only moderately effective or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude it from obtaining marketing approval or prevent or limit commercial use.

The process of obtaining regulatory approvals, both in the United States and abroad, is expensive, may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity and novelty of the product candidate involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted IND/BLA, or equivalent application types, may cause delays in the approval or rejection of an application. The FDA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that its data are insufficient for approval and require additional preclinical, clinical or other studies. Any product candidate Forte seeks to develop could be delayed in receiving, or fail to receive, regulatory approval for many reasons, including the following:

44

Of the large number of biopharmaceutical products in development, only a small percentage successfully complete the FDA or foreign regulatory approval processes and are commercialized. The lengthy approval process as well as the unpredictability of future clinical trial results may result in Forte failing to obtain regulatory approval to market its product candidate, which would significantly harm its business, results of operations and prospects.

The FDA may also require a panel of experts, referred to as an Advisory Committee, to deliberate on the adequacy of the safety and efficacy data to support approval. The opinion of the Advisory Committee, although not binding, may have a significant impact on its ability to obtain approval of any product candidate that Forte develops based on the completed clinical trials.

In addition, even if Forte were to obtain approval, regulatory authorities may approve its product candidate for fewer or more limited indications than Forte requests, may include limitations for use or contraindications that limit the suitable patient population, may not approve the price Forte intends to charge for its products, may grant approval contingent on the performance of costly post-marketing clinical trials or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate. Any of the foregoing scenarios could materially harm the commercial prospects for any product candidate Forte develops.

If Forte experiences delays in obtaining approval or if Forte fails to obtain approval of any product candidate it seeks to develop, the commercial prospects for such product candidate may be harmed, and its ability to generate revenues will be materially impaired.

Forte’s product candidate, FB-102, or any future product candidate Forte develops, may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by any of its product candidates could cause Forte to interrupt, delay or halt preclinical studies or could cause Forte or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive clinical label or the delay or denial of regulatory approval by the FDA or other regulatory authorities for its product candidate. Results of its clinical studies or trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, its clinical studies or trials could be suspended or terminated, and the FDA or comparable foreign regulatory authorities could order Forte to cease further development of or deny approval of its product candidate for any or all targeted indications. Additionally, its regulators could require significant modifications or amendments to ongoing clinical studies or trials that limit the available study population or lead to withdrawal of participation by already enrolled subjects. Any treatment-related side effects could affect patient recruitment or the ability of enrolled patients to complete the study or trial or result in potential product liability claims. Any of these occurrences may harm Forte’s business, financial condition and prospects significantly.

Further, clinical studies or trials by their nature utilize a sample of the potential patient population. With a limited number of patients and limited duration of exposure, rare and severe side effects of its product candidate may only be uncovered with a significantly larger number of patients exposed to the product candidate. If its product candidate receives marketing approval and Forte or others identify undesirable side effects caused by such product

45

candidate (or any other similar drugs) after such approval, a number of potentially significant negative consequences could result, including:

Forte believes that any of these events could prevent it from achieving or maintaining market acceptance of the affected product candidate and could substantially increase the costs of commercializing its product candidate, if approved, and significantly impact its ability to successfully commercialize its product candidate and generate revenues.

Even if Forte receives regulatory approval of any product candidate, Forte will be subject to ongoing regulatory compliance obligations and continued regulatory review, which may result in significant additional expense. Additionally, if Forte fails to comply with regulatory requirements or experiences unanticipated problems with its product candidate, if approved, Forte could be subject to labeling and other restrictions, market withdrawal, and penalties.

If FB-102 or any other product candidate Forte develops is approved, it will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, distribution, advertising, promotion, sampling, record-keeping, export, import, conduct of post-marketing studies and submission of safety, efficacy and other post-market information, including both federal and state requirements in the United States and requirements of comparable foreign regulatory authorities. In addition, Forte will be subject to continued compliance with cGMP and GCP requirements for any clinical trials that Forte conducts post-approval.

Manufacturers and manufacturers’ facilities are required to comply with extensive FDA, and comparable foreign regulatory authority requirements, including ensuring that quality control and manufacturing procedures conform to cGMP regulations. As such, Forte and its contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any NDA, other marketing application, and previous responses to inspection observations. Accordingly, Forte and others with whom Forte works must continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

The FDA has significant post-marketing authority, including, for example, the authority to require labeling changes based on new safety information and to require post-marketing studies or clinical trials to evaluate serious safety risks related to the use of a drug. Any regulatory approvals that Forte receives for a product candidate may be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials and

46

surveillance to monitor the safety and efficacy of the product candidate. The FDA may also require a REMS program as a condition of approval of any product candidate Forte develops, which could entail requirements for long-term patient follow-up, a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. In addition, if the FDA or a comparable foreign regulatory authority approves a product candidate, Forte will have to comply with requirements including submissions of safety and other post-marketing information and reports and registration.

The FDA may impose consent decrees or withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with any product candidate Forte develops, including adverse events of unanticipated severity or frequency, or with its third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of distribution restrictions or other restrictions under a REMS program. Other potential consequences include, among other things:

The FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market. Products may be promoted only for the approved indications and in accordance with the provisions of the approved label or other regulatory marketing pathway. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses and a company that is found to have improperly promoted off-label uses may be subject to significant liability. However, physicians may, in their independent medical judgment, prescribe legally available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments but the FDA does restrict manufacturer’s communications on the subject of off-label use of their products. In addition, the policies of the FDA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of any product candidate Forte develops. If Forte is slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if Forte is not able to maintain regulatory compliance, Forte may lose any marketing approval that Forte may have obtained which would adversely affect its business, prospects and ability to achieve or sustain profitability.

The policies of the FDA and of other regulatory authorities may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of any product candidate Forte develops. The government may also implement additional measures in response to the COVID-19 pandemic. Forte also cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative or executive action, either in the United States or abroad. To the extent any legislative, administrative, or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, its business may be negatively impacted. In addition, if Forte is slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if Forte is not able to maintain regulatory compliance, Forte may lose any marketing approval that Forte may have obtained, and Forte may not achieve or sustain profitability.

Non-compliance by Forte or any future collaborator with regulatory requirements, including safety monitoring or pharmacovigilance requirements, can also result in significant financial penalties.

47

Forte’s business activities may be subject to the FCPA and similar anti-bribery and anti-corruption laws of other countries in which Forte operates, as well as U.S. and certain foreign export controls, trade sanctions, and import laws and regulations. Compliance with these legal requirements could limit its ability to compete in foreign markets and subject it to liability if Forte violates them.

If Forte expand its operations outside of the United States, Forte must dedicate additional resources to comply with numerous laws and regulations in each jurisdiction in which Forte plans to operate. The FCPA prohibits any U.S. individual or business from paying, offering, authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with certain accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials. Certain payments to hospitals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. If Forte expands its presence outside of the United States, it will require Forte to dedicate additional resources to comply with these laws, and these laws may preclude Forte from developing, manufacturing, or selling any product candidates, if approved, outside of the United States, which could limit its growth potential and increase its development costs.

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting. The Securities and Exchange Commission, or SEC, also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA’s accounting provisions.

Additionally, U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions, and other trade laws and regulations, which are collectively referred to as Trade Laws, prohibit companies and their employees, agents, clinical research organizations, legal counsel, accountants, consultants, contractors, and other partners from authorizing, promising, offering, providing, soliciting, or receiving directly or indirectly, corrupt or improper payments or anything else of value to or from recipients in the public or private sector. Violations of Trade Laws can result in substantial criminal fines and civil penalties, imprisonment, the loss of trade privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences. Forte has direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations. Forte also expects its non-U.S. activities to increase in time. Forte plans to engage third parties for clinical trials and/or to obtain necessary permits, licenses, patent registrations, and other regulatory approvals and Forte can be held liable for the corrupt or other illegal activities of its personnel, agents, or partners, even if Forte do not explicitly authorize or have prior knowledge of such activities.

48

Compliance with applicable regulatory requirements regarding the export of any of Forte’s current and future approved products may create delays in the introduction of its products in international markets or, in some cases, prevent the export of its products to some countries altogether. Furthermore, U.S. export control laws and economic sanctions prohibit the shipment of certain products and services to countries, governments, and persons targeted by U.S. sanctions. If Forte fails to comply with export and import regulations and such economic sanctions, penalties could be imposed, including fines and/or denial of certain export privileges. Moreover, any new export or import restrictions, new legislation or shifting approaches in the enforcement or scope of existing regulations, or in the countries, persons, or products targeted by such regulations, could result in decreased use of its products by, or in its decreased ability to export its approved products to, existing or potential customers with international operations. Any decreased use of its approved products or limitation on its ability to export or sell its products would likely adversely affect Forte’s business.

Risks related to Forte’s intellectual property

If Forte is unable to obtain and maintain patent protection for any product candidate Forte develops, its competitors could develop and commercialize products or technology similar or identical to Forte’s, and its ability to successfully commercialize any product candidate Forte may develop, and its technology, may be adversely affected.

Forte’s success depends in large part on its ability to obtain and maintain patent protection in the United States and other countries with respect to any product candidate and other technologies Forte may develop. Given that the development of its technology is at an early stage, its intellectual property portfolio with respect to certain aspects of its technology and any product candidates is also at an early stage. Forte has filed and intends to file patent applications on these aspects of its technology and any product candidates; however, there can be no assurance that any such patent applications will issue as granted patents.

Composition of matter patents for biological and pharmaceutical products are generally considered to be the strongest form of intellectual property protection for those types of products, as such patents provide protection without regard to any method of use. Forte cannot be certain, however, that the claims in its future patent applications covering the composition of matter of any product candidates will be considered patentable by the United States Patent and Trademark Office (“USPTO”), or by patent offices in foreign countries, or that the claims in any of its issued patents will be considered valid and enforceable by courts in the United States or foreign countries.

Furthermore, in some cases, Forte may not be able to obtain issued claims covering compositions of matter relating to any product candidates it develops and instead may need to rely on filing patent applications with claims covering a method of use and/or method of manufacture. Method of use patents protect the use of a product for the specified method. This type of patent does not prevent a competitor from making and marketing a product that is identical to any product Forte develops for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their products for its targeted indications, physicians may prescribe these products “off-label” for those uses that are covered by its method of use patents. Although off-label prescriptions may infringe or contribute to the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute. There can be no assurance that any such patent applications will issue as granted patents, and even if they do issue, such patent claims may be insufficient to prevent third parties, such as Forte’s competitors, from utilizing its technology. Any failure to obtain or maintain patent protection with respect to any product candidate Forte develops could have a material adverse effect on Forte’s business, financial condition, results of operations, and prospects.

If the scope of any patent protection Forte obtains is not sufficiently broad, or if Forte loses any future patent protection, its ability to prevent its competitors from commercializing similar or identical technology and product candidates would be adversely affected.

The patent position of healthcare companies generally is highly uncertain, involves complex legal and factual questions, and has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of any future patent rights are highly uncertain. Forte’s future patent applications may not result in patents being issued which protect any product candidates Forte develops, or other technologies or which effectively prevent others from commercializing competitive technologies and product candidates.

No consistent policy regarding the scope of claims allowable in patents in the biotechnology field has emerged in the United States. The patent situation outside of the United States is even more uncertain. Changes in either the patent laws or their interpretation in the United States and other countries may diminish Forte’s ability to protect its inventions and enforce its intellectual property rights, and more generally could affect the value of its intellectual property. In particular, its ability to stop third parties from making, using, selling, offering to sell, or importing products that infringe its intellectual property will depend in part on its success in obtaining and enforcing patent claims that cover its technology, inventions and improvements. With respect to company-owned intellectual property, Forte cannot be sure that patents will be granted with respect to any patent applications filed by it in the future, nor can Forte be sure any patents that may be granted to Forte in the future will be commercially useful in protecting its products and the methods used to manufacture those products. Moreover, even any patents that may issue to Forte do not guarantee Forte the right to practice its technology in relation to the commercialization of its products. The area of patent and other intellectual property rights in biotechnology is an evolving one with many risks and uncertainties, and third parties may have blocking patents that could be used to prevent Forte from commercializing any future product candidates. Any patents that may issue to Forte in the future may be challenged, invalidated, or circumvented, which could limit its ability to stop competitors from marketing related products or limit the length of the term of patent protection that Forte may have for any product candidate it develops. In addition, the rights granted under any patents that may issue to Forte may not provide Forte with protection or competitive advantages against competitors with similar technology. Furthermore, its competitors may independently develop similar technologies. For these reasons, Forte may have competition for any product candidate it develops. Moreover, because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before any particular product candidate can be commercialized, any related patent that may issue to Forte may expire or remain in force for only a short period following commercialization, thereby reducing any advantage of the patent.

Any patents that Forte may own in the future may be challenged, narrowed, circumvented, or invalidated by third parties. Consequently, Forte does not know whether any product candidate or other technologies it develops will be protectable or remain protected by valid and enforceable patents. Forte’s competitors or other third parties may be able to circumvent Forte’s future patents by developing similar or alternative technologies or products in a non-infringing manner which could materially adversely affect its business, financial condition, results of operations and prospects.

The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and patents that Forte may obtain may be challenged in the courts or patent offices in the United States and abroad. Forte may be subject to a third party preissuance submission of prior art to the USPTO or to foreign patent authorities or become involved in opposition, derivation, revocation, reexamination, post-grant and inter partes review, or interference proceedings or other similar proceedings challenging future patent rights. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate or render unenforceable, Forte’s future patent rights, allow third parties to commercialize any product candidates Forte develops or other technologies, and compete directly with Forte, without payment to Forte, or result in Forte’s inability to manufacture or commercialize products without infringing third-party patent rights. Moreover, Forte may have to participate in interference proceedings declared by the USPTO to determine priority of invention or in post-grant challenge proceedings, such as oppositions in a foreign patent office, that challenge its priority of invention or other features of

patentability with respect to any future owned patents and patent applications. Such challenges may result in loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit its ability to stop others from using or commercializing similar or identical technology and products, or limit the duration of the patent protection of any product candidates Forte develops. Such proceedings also may result in substantial cost and require significant time from its scientists and management, even if the eventual outcome is favorable to us.

In addition, given the amount of time required for the development, testing, and regulatory review of future product candidates, Forte’s future patents protecting such a product candidate might expire before or shortly after any such product candidate is approved and commercialized. As a result, its intellectual property may not provide Forte with sufficient rights to exclude others from commercializing products similar or identical to ours.
