Item 1A. Risk Factors.

Risk Factors Summary

We are subject to a number

of risks that could harm our business, financial condition, results of operations and/or growth prospects or cause our actual results

to differ materially from those contained in forward-looking statements we have made in this Form 10-K and those we may make from time

to time. The success of our product candidates will depend on a variety of factors. We do not have complete control over many of these

factors, including certain aspects of clinical development and the regulatory submission process, potential threats to our intellectual

property rights and the manufacturing, marketing, distribution and sales efforts of any current or future collaborator. In addition, some

of the factors, events and contingencies discussed below may have occurred in the past, but the disclosures below are not representations

as to whether or not the factors, events or contingencies have occurred in the past and instead reflect our beliefs and opinions as to

the factors, events, or contingencies that could materially and adversely affect us in the future.

The following summary is

not exhaustive and is qualified by reference to the full set of risk factors set forth in Item 1A “Risk Factors” of this Form

10-K. Please carefully consider all the information in this Form 10-K, including the full set of risks set forth in the “Risk Factors”

section and in our other filings with the U.S. Securities and Exchange Commission (“SEC”), before making an investment decision

regarding the Company.

Risk Factors

Risks Related to Our Financial

Condition and Capital Requirements

We are a clinical

stage biopharmaceutical company with a limited operating history on which to assess our business; our clinical trials are ongoing, we

have no products approved for commercial sale, we have historically incurred losses, and we anticipate that we will continue to incur

significant losses for the foreseeable future. Moreover, we have never generated revenue from product sales and may never be profitable.

We are a clinical stage biopharmaceutical

company with a limited operating history. We will need to raise substantial additional capital to continue to fund our operations in the

future. We have based our estimates on assumptions that may prove to be wrong and we could exhaust our available financial resources sooner

than we currently anticipate. We have devoted substantially all of our financial resources to identifying, acquiring, and developing our

product candidates, organizing and staffing our company, and providing general and administrative support for our operations.

Additional capital may not

be available in sufficient amounts or on reasonable terms, if at all. The current market environment for small and midcap biotechnology

companies and broader macroeconomic factors may preclude us from successfully raising additional capital on the timeline we require. For

example, escalating geopolitical tensions, elevated interest rates, and economic and regulatory uncertainty have caused market volatility.

Such volatility can have an adverse effect on the ability to raise capital, particularly in the biotechnology and biopharmaceutical industries.

In addition, it may be difficult for us to raise additional capital if we experience any issues that delay or prevent the regulatory approval

or our ability to commercialize any of our product candidates.

Biopharmaceutical product development is a highly speculative undertaking

and involves a substantial degree of risk. We expect our losses to increase as our product candidates enter advanced clinical trials.

It may be several years, if ever, before we complete pivotal clinical trials or have a product candidate approved for commercialization.

We expect to invest significant funds into the research and development of our programs to determine the potential to advance product

candidates to regulatory approval. If we obtain regulatory approval to market a product candidate, our future revenue will depend upon

the size of approved markets, and our ability to achieve sufficient market acceptance, pricing, coverage and adequate reimbursement from

third-party payors, and adequate market share for our products. However, even if we obtain adequate market share for our products,

we may never become profitable despite obtaining such market share and acceptance of our products.

We expect to continue to

incur significant expenses and increasing operating losses for the foreseeable future and our expenses will increase substantially if

and as we:

● seek to maintain, protect, and expand our intellectual property portfolio; and

38

If we are unable to raise

additional capital when required or on acceptable terms, we may be required to curtail our product development activities and other activities

commensurate with the magnitude of the shortfall and our product development activities may cease altogether, which could materially harm

our business, financial condition, and results of operations. To the extent that the costs of our activities exceed our current estimates

and we are unable to raise sufficient additional capital to cover such costs, we will need to reduce operating expenses, sell assets,

enter into strategic transactions, or effect a combination of the above. No assurance can be given that we will be able to enter into

any of such transactions on acceptable terms, if at all. Any of the following events could have a material adverse effect on our business,

operating results, and prospects:

● filing for bankruptcy or ceasing operations altogether.

Even if we are successful

in raising additional capital, the amount of capital we raise may be limited or restricted due to investor demand, market conditions, or other

factors.

Raising additional

capital may cause dilution to our stockholders, restrict our operations, or require us to relinquish rights.

To the extent that we raise additional capital through the sale of equity securities or convertible debt securities, the ownership interest

of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect

the rights of holders of our common stock. Debt financing and preferred equity financing, if available, may involve agreements that include

covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures,

or declaring dividends. For example, in September 2024, we entered into a Securities Purchase Agreement with certain institutional and

accredited investors, whereby the investors purchased an aggregate of 5,600,000 shares of common stock, 2,439 shares of Series A Preferred

Stock and pre-funded warrants to purchase an aggregate of 680,000 shares of common stock and in November 2024, each outstanding share

of Series A Preferred Stock converted into 1,000 shares of common stock. Furthermore, in September 2025, we entered into a Securities

Purchase Agreement with certain institutional and accredited investors, whereby the investors purchased an aggregate of 10,933,405 shares

of our common stock and pre-funded warrants to purchase 1,066,666 shares of common stock. In addition, in October 2025, we entered into

a sales agreement with TD Securities (USA) LLC acting as our sales agent pursuant to which we may issue and sell shares of our common

stock from time to time through an at-the-market equity offering program, for aggregate gross proceeds of up to $200.0 million, under

which we have sold shares of our common stock resulting in net proceeds of $38.9 million as of March 2026.

Moreover, if we raise additional

funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required

to relinquish valuable rights to our research programs or product candidates or grant licenses on terms that may not be favorable to us.

Risks Related to Clinical

Development, Regulatory Approval and Commercialization

We face competition

from entities that have developed or may develop programs for the diseases addressed by our product candidates.

The development and commercialization

of drugs is highly competitive. If approved, our product candidates will face significant competition and our failure to effectively compete

may prevent us from achieving significant market penetration. Many of the companies with which we are currently competing or will compete

against in the future have significantly greater financial resources and expertise in research and development, manufacturing, preclinical

testing, clinical trials, regulatory approvals, and marketing than we do. Mergers and acquisitions in the pharmaceutical and biotechnology

industry may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies

may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These

competitors also compete with us in establishing clinical trial sites, recruiting participants for clinical trials, as well as in acquiring

technologies complementary to, or necessary for, our product candidates.

39

Our competitors have developed,

are developing, or may develop programs and processes that compete with ours. Our success will depend partially on our ability to develop

and commercialize products that have a competitive safety, efficacy, dosing and/or presentation profile. Our commercial opportunity and

success may be reduced or eliminated if competing products are safer, more effective, have a more attractive dosing profile or presentation,

or are less expensive than our products, or if biosimilars enter the market and achieve broader or more rapid market acceptance than our

products.

Our product candidates

may fail in development or suffer delays. We depend on the successful initiation and completion of clinical trials for our product candidates

to advance our product development plans.

We expect it will be many years

before we can obtain regulatory approval for and commercialize any product candidate, if ever. Clinical testing is expensive, difficult

to design and implement, and can take years to complete and is uncertain as to outcome. A failure of one or more of our clinical trials

can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of

later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Moreover, preclinical and clinical

data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed

satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval for their products.

We may experience a number

of events affecting our product development timeline, including the following:

40

If our clinical trials do not produce favorable results, our ability

to obtain regulatory approval for our product candidates will be adversely impacted. Moreover, the combined data from our trials may be

inconclusive or may not be sufficient to ultimately gain marketing approval from the FDA or other regulatory authorities. There are equivalent

processes and risks applicable to clinical trial applications in other countries outside of the United States, including the European

Union (“EU”).

In addition, in part due to the competitive landscape for immunology

and inflammation (commonly referred to as “I&I”) indications, we may also face increased competition for clinical trial

enrollment. Clinical trial enrollment will depend on many factors, including if potential clinical trial participants choose to undergo

treatment with approved products or enroll in competitors’ clinical trials for programs that are under development for the same

indications as our programs. An increase in the number of approved products for the indications we are targeting with our programs may

further exacerbate this competition. Our inability to enroll a sufficient number of participants could, among other things, delay our

development timeline, which may further harm our competitive position and have an adverse effect on our business and operations.

We are substantially

dependent on the success of our two most advanced programs, ORKA-001 and ORKA-002, and our clinical trials of such programs may not be

successful.

Our future success is substantially

dependent on our ability to develop and timely obtain marketing approval for, and then successfully commercialize, our two most advanced

programs, ORKA-001 and ORKA-002. We are investing the majority of our efforts and financial resources into the research and development

of these programs. Our Phase 1 clinical trial of ORKA-001 in healthy volunteers is fully enrolled and is ongoing for purposes of continued

patient follow-up and data collection, and remains blinded. Our Phase 2a clinical trial of ORKA-001 in patients with moderate-to-severe

psoriasis (“PsO”) remains ongoing and we commenced dosing in a dose-ranging Phase 2b trial of ORKA-001 in moderate-to-severe

PsO in the fourth quarter of 2025.

Our Phase 1 clinical trial

of ORKA-002 in healthy volunteers is fully enrolled and remains ongoing for purposes of continued patient follow-up and data collection,

and remains blinded. In addition, we expect to commence a Phase 2 clinical trial of ORKA-002 in patients with moderate-to-severe PsO in

the first half of 2026 and plan to initiate a Phase 2 clinical trial of ORKA-002 in hidradenitis suppurativa (“HS”) in

the second half of 2026.

Currently, we believe that the success of our programs is dependent

on our product candidates demonstrating a longer half-life in humans than monoclonal antibodies currently marketed and in development

as we believe this longer half-life has the potential to result in a more favorable dosing schedule for our product candidates, assuming

they successfully complete clinical development and obtain marketing approval. To the extent we do not observe this extended half-life,

it would significantly and adversely affect the clinical and commercial potential of our product candidates.

If we do not achieve our projected development goals in the time frames

we announce or expect, the development and potential commercialization of our product candidates may be delayed and our expenses may increase

and, as a result, our business may be materially harmed and our stock price may decline.

From time to time, we announce the timing of the anticipated accomplishment

of various scientific, clinical, regulatory, or other product development goals, which we sometimes refer to as milestones. These milestones

may include the commencement or completion of scientific studies and clinical trials, such as the expected timing of our clinical trials

in our target indications, anticipated data analysis, and the data results from our clinical trials, as well as the submission of regulatory

filings. All of these milestones are and will be based on numerous assumptions. The actual timing of these milestones can vary dramatically

compared to our estimates, in some cases for reasons beyond our control. If we do not meet these milestones or the timing of the milestones

as publicly announced, the development and potential commercialization of our product candidates may be delayed or never achieved

and, as a result, our business may be materially harmed and our stock price may decline. Additionally, delays relative to our projected

timelines are likely to cause overall expenses to increase, which may require us to raise additional capital sooner than expected and

on terms less than desirable, and prior to achieving targeted development milestones.

41

Any drug delivery device

that we may use to deliver our product candidates may have its own regulatory, development, supply and other risks.

We are delivering and expect

to continue to deliver, our product candidates via a drug delivery device, such as pre-filled syringe, an injector, or other delivery

system. We currently expect to utilize drug delivery devices authorized for marketing under clearances of approvals held by third parties.

Where approval of a drug product and device is sought under a single application, the increased complexity of the review process may delay

approval. Our product candidates may not be approved or may be substantially delayed in receiving approval if the devices that we choose

to develop do not gain and/or maintain their own regulatory approvals or clearances. In addition, some drug delivery devices are provided

by single-source third-party companies. We may be dependent on the sustained cooperation and effort of those third-party companies both

to supply the devices and, in some cases, to conduct the studies required for approval or other regulatory clearance of the devices. Even

if approval is obtained for our products, we may also be dependent on those third-party companies continuing to maintain such approvals

or clearances, if required, for their drug delivery devices once they have been received. Moreover, there may be unforeseen technical

complications related to the development activities required to bring such a product to market, including primary container compatibility

and/or dose volume requirements. Failure of third-party companies to supply the devices on time and in accordance with the agreed-upon

specifications, to successfully complete studies on the devices in a timely manner, or to obtain or maintain required approvals or clearances

of the devices could result in increased development costs, delays in or failure to obtain regulatory approval and delays in product candidates

reaching patients.

Our approach to the discovery and development of our lead programs

is unproven, and we may not be successful in our efforts to build a pipeline of programs with commercial value.

We have worked with Paragon

to leverage clinically validated mechanisms of action and incorporate advanced antibody engineering to optimize half-life and other properties

designed to overcome limitations of existing therapies. We have entered into antibody discovery and option agreements (the “Option

Agreements”) with Paragon Therapeutics, Inc. (“Paragon”) and Paruka Holding LLC to facilitate the discovery and development

of certain research programs with respect to which we have signed a license agreement with Paragon. Our two most advanced programs, ORKA-001

and ORKA-002, are licensed from Paragon and are purposefully designed to improve upon existing product candidates and products while maintaining

the same, well-established mechanisms of action. However, the scientific research that forms the basis of our efforts to develop programs

using half-life extension technologies is ongoing and may not result in viable programs. There is limited clinical data available on product

candidates utilizing half-life extension technologies, especially in I&I indications, demonstrating whether they are safe or effective

for long-term treatment in humans. The long-term safety and efficacy of these technologies and the extended half-lives and exposure profiles

of our programs compared to currently approved products are unknown.

We may ultimately discover

that utilizing half-life extension technologies for our specific targets and indications and any programs resulting therefrom does not

possess certain properties required for therapeutic effectiveness. In addition, programs using half-life extension technologies may demonstrate

different chemical and pharmacological properties in human participants than they do in laboratory studies or preclinical studies, including

the inability to demonstrate the same chemical and pharmacological properties in humans or the potential interaction with human biological

systems in unforeseen, ineffective, or harmful ways.

If the products resulting

from the research programs with respect to which we have signed license agreements with Paragon prove to be ineffective, unsafe or commercially

unviable, such programs would have little, if any, value, which would have a material and adverse effect on our business, financial condition,

results of operations, and prospects.

In addition, we may in the future seek to discover and develop programs

that are based on novel targets and in the technologies that are unproven. If our discovery activities fail to identify novel targets

or technologies for drug discovery, or such targets prove to be unsuitable for treating human disease, we may not be able to develop viable

additional programs.

42

Preclinical and clinical development involves a lengthy and expensive

process that is subject to delays and uncertain outcomes and results of earlier studies and trials may not be predictive of future clinical

trial results. Further, if our preclinical studies and clinical trials are not sufficient to support regulatory approval of any of our

product candidates, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development

of such product candidate.

We do not know whether any

clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market any of our product

candidates. Clinical testing can take many years to complete, and its outcome is inherently uncertain. Our clinical trials may not be

conducted as planned or completed on schedule, if at all, and failure can occur at any time during the preclinical study or clinical trial

process. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of

later-stage clinical trials and results in one indication may not be predictive of results to be expected for the same product candidate

in another indication. We plan to use the data from our current trials of our ORKA-001 and ORKA-002 programs to support further trials

in PsO, HS, and potentially other I&I indications. However, differences between early-stage clinical trials and later-stage clinical

trials, including differences in trial design, among other things, make it difficult to extrapolate the results of earlier clinical trials

to later clinical trials. A number of companies in the biopharmaceutical industry have suffered significant setbacks in advanced clinical

trials due to lack of efficacy or unfavorable safety profiles, notwithstanding promising results in earlier trials. Moreover, clinical

data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed

satisfactorily in clinical trials have nonetheless failed to obtain marketing approval of such product candidates. In addition, we rely

on clinical trial site staff to measure psoriasis area severity index scores (PASI scores) and participants to provide feedback on measures

such as measures of quality of life, which may involve subjective interpretation and variability, although training and standardized measurements

will be provided to individuals in order to minimize subjectivity. Moreover, these measures can be influenced by factors outside of our

control, and can vary widely within a clinical trial.

We cannot be sure that the FDA, or comparable foreign regulatory authority,

as applicable, will agree with our clinical development plan. We cannot assure that the submission of an Investigational New Drug (IND)

application, clinical trial application, or similar application will result in the FDA or comparable foreign regulatory authorities, as

applicable, allowing clinical trials to begin in a timely manner, if at all. If the FDA and/or comparable foreign regulatory authority

requires us to materially modify our proposed trial designs, conduct additional trials or enroll additional participants, our development

timelines may be delayed. Moreover, even if these trials begin, issues may arise that could suspend or terminate such clinical trials,

including but not limited to delays or difficulties recruiting trial patients, delays or difficulties obtaining required IRB or ethics

committee approval at each clinical trial site, failure by third parties or us to adhere to clinical trial protocols or failure to perform

in accordance with current Good Clinical Practice or applicable regulatory requirements, or delays in reaching a consensus with regulatory

authorities on trial design or implementation of a clinical trial, or our third party vendors not satisfying their obligations to us.

We could also encounter delays if a clinical trial is required to

be materially modified or suspended or terminated by us, the IRBs, by a Data Safety Monitoring Board, if any, or by the FDA or comparable

foreign regulatory authorities. Such authorities may suspend, put on clinical hold, or terminate a clinical trial due to a number of

factors, including not aligning with or supporting our clinical trial designs or our failure to conduct the clinical trial in accordance

with regulatory requirements or our clinical trial protocols, inspection of the clinical trial operations or trial site by the FDA or

comparable foreign regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects,

failure to demonstrate a benefit, changes in governmental regulations or administrative actions or lack of adequate funding to continue

the clinical trial. If we are required to conduct additional clinical trials or other testing of our product candidates beyond those

that we currently contemplate, if we are unable to successfully complete clinical trials of our product candidates, if the results of

these trials are not positive or are only moderately positive, or if there are safety concerns, our business and results of operations

may be adversely affected and we may need to adjust or abandon our business plans and we may incur significant additional costs.

Our clinical development activities could be delayed or otherwise adversely

affected if we encounter difficulties enrolling and maintaining participants in our current and future clinical trials. We depend on

the successful completion of clinical trials for our product candidates.

Our inability to enroll and maintain a sufficient number of participants

who remain in a trial until conclusion would result in significant delays in completing clinical trials and increased development costs

or may require us to abandon one or more clinical trials altogether. The enrollment of participants in current or future trials for any

of our programs will depend on many factors, including if participants choose to enroll in our clinical trials, rather than using approved

products, or if our competitors have ongoing clinical trials for programs that are under development for the same indications as our programs

and participants instead enroll in such clinical trials. Even if we are able to enroll a sufficient number of participants for our clinical

trials, we may have difficulty maintaining participants in such clinical trials.

43

Preliminary, “topline”, or interim data from our clinical

trials may change and are subject to audit and verification procedures, and should be viewed with caution until the final data are available.

Our interpretation of such data is based on assumptions that may evolve as additional data become available, which could result in changes

to conclusions regarding the safety, efficacy, timing, or likelihood of success of our clinical development programs.

From time to time, we may

publicly disclose preliminary or topline data from our preclinical studies and clinical trials that are based on a preliminary analysis

of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review

of the data. We may also make assumptions, estimations, calculations, and conclusions as part of our analyses of these data without the

opportunity to fully and carefully evaluate complete data. As a result, the preliminary or topline results that we report may differ from

future results of the same studies and our conclusions may change or be qualified as additional data are received, fully evaluated, and

subjected to audit and verification procedures.

We may also publicly disclose

interim data from our preclinical studies and clinical trials. Such interim data are inherently preliminary and subject to the risk that

one or more of the clinical outcomes may change as participant enrollment continues, additional data become available, as participants

from our clinical trials pursue other treatments, or further analyses are conducted. In addition, third parties, including regulatory

agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions, or analyses or may interpret or weigh the

importance of data differently, which could impact the perceived value of the particular product candidate, the approvability or commercialization

of the particular product candidate, and our company and our business in general. In addition, others may not agree with what we determine

is material or otherwise appropriate information to include in our public disclosure of a particular preclinical study or clinical trial.

If the preliminary, topline, or interim data that we report differ

from actual results, or if final data or data from later stage clinical trials do not produce favorable results, our ability to obtain

approval for, and commercialize, our product candidates may be harmed, which could harm our business, operating results, prospects or

financial condition.

Our clinical trials may reveal significant adverse events, undesirable

side effects, or patient intolerance not seen in our preclinical studies or earlier clinical trials, and may result in a safety profile

that could halt clinical development, inhibit regulatory approval, or limit commercial potential or market acceptance of any of our product

candidates. We do not know whether any clinical trials we may conduct will demonstrate adequate efficacy and safety to result in regulatory

approval to market any of our product candidates.

Results of our clinical trials

could reveal an unacceptable severity and prevalence of side effects or patient intolerance, adverse events, or unexpected characteristics,

and any of these occurrences could harm our business, financial condition, results of operations and prospects significantly. If significant

adverse events or other side effects are observed in any of our clinical trials, we may have difficulty recruiting participants to such

trials, participants may drop out of the trials, or we may have to suspend, materially modify or abandon the trials or our development

efforts of one or more programs altogether. We, the FDA or other applicable regulatory authorities, or an IRB, may suspend or require

the material modification of any clinical trials of any program or require that we repeat or conduct additional clinical trials at any

time for various reasons, including safety and health risks or exposure to adverse side effects.

Even if side effects do not

preclude the product candidate from obtaining or maintaining marketing approval, undesirable side effects may inhibit market acceptance

of the approved product due to their tolerability versus other therapies. Potential side effects associated with our product candidates

may not be appropriately recognized or managed by the treating medical staff, as toxicities resulting from our product candidates may

not be normally encountered in the general patient population and by medical personnel. In addition, an extended half-life could prolong

the duration of undesirable side effects, which could also affect our clinical trials or inhibit market acceptance.

In addition, even if we successfully

advance our product candidates through clinical trials, such trials will only include a limited number of participants and limited duration

of exposure to our product candidates. As a result, we cannot be assured that adverse effects of our product candidates will not be uncovered

when a significantly larger number of participants are exposed to the product candidate after approval and potentially over an extended

period of use. Further, any clinical trials may not be sufficient to determine the effect and safety consequences of using our product

candidates over a multi-year period or longer.

If any of the foregoing events occur or if one or more of our product

candidates prove to be unsafe, our pipeline could be affected, which would have a material adverse effect on our business, financial condition,

results of operations, and prospects.

44

We may expend our limited

resources to pursue a particular program and fail to capitalize on programs that may be more profitable or for which there is a greater

likelihood of success.

We are initially focused on our most advanced programs, ORKA-001 and

ORKA-002, and as a result, we may forgo or delay pursuit of opportunities with other programs that later prove to have greater commercial

potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities.

Our spending on current and future research and development programs for specific indications may not yield any commercially viable product

candidates. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may be in

a position where we may have to relinquish valuable rights to that product candidate through collaboration, licensing or other arrangements

in cases in which we would have been more advantageous for us to retain sole development and commercialization rights to such product

candidate. We may never receive approval to market and commercialize any product candidate.

Any approved products

resulting from our programs may not achieve adequate market acceptance among clinicians, patients, healthcare third-party payors and others

in the medical community necessary for commercial success and we may not generate any future revenue from the sale or licensing of such

products.

Even if regulatory approval is obtained for a product candidate resulting

from one of our current or future programs, it may not gain market acceptance among physicians, patients, third-party payors or others

in the medical community. Market acceptance of our product candidates will depend on many factors, including factors that are not within

our control. Market participants with influence over acceptance of new treatments, such as clinicians and third-party payors,

may not adopt a biologic that incorporates half-life extension for our targeted indications, and we may not be able to convince the

medical community and third-party payors to accept and use, or to provide favorable reimbursement for, any programs developed by

us or our existing or future collaborators. Moreover, an extended half-life may make it more difficult for patients to change treatments

and there may be a perception that half-life extension could exacerbate side effects, each of which may adversely affect our ability

to gain market acceptance. Further, we may not generate or derive sufficient revenue from a product candidate and may not become or remain

profitable if such product candidate is approved, but does not achieve an adequate level of acceptance.

Certain of our programs

may compete with our other programs, which could negatively impact our business and reduce our future revenue.

We are developing product candidates for PsO, HS, and may in the future

develop our programs for other I&I indications. Each such program targets a different mechanism of action. However, developing multiple

programs for a single indication may negatively impact our business if the programs compete with each other. For example, concurrent clinical

trials across multiple programs may compete for the enrollment of participants. In addition, the approval of multiple product candidates

for the same indication could intensify market competition and limit our future revenues.

We are conducting, and may conduct in the future, clinical trials for

programs at sites outside the United States, subjecting us to additional risks that may delay or adversely affect our product development

timelines.

We are currently conducting

clinical trials outside the United States and may continue to do so in the future. Conducting clinical trials outside the United States

may expose us to additional operational and regulatory risks, including differing regulatory standards and review timelines and increased

complexity in ensuring compliance with applicable laws and data protection requirements. Although the FDA may accept data from clinical

trials conducted outside the United States, acceptance of this data is subject to conditions imposed by the FDA. If the FDA does not accept

the data from any trial that we conduct outside the United States, it would likely result in the need for additional trials, which would

be costly and time-consuming and would delay or permanently halt our development of the applicable product candidates. Even if the FDA

accepted such data, it could impose additional conditions, such as requiring us to modify our planned clinical trials to receive clearance

to initiate such trials in the United States or to continue such trials once initiated.

Further, conducting clinical trials outside of the United States presents

additional risks that may delay completion of our clinical trials. These risks include requirements for local ethics approvals, challenges

in monitoring trial conduct and data integrity across jurisdictions, including the potential failure of investigators or enrolled participants

in foreign countries to adhere to clinical protocol that could restrict or limit our ability to conduct our clinical trials, the administrative

burdens of conducting clinical trials under multiple sets of foreign regulations, potential restrictions, such as local privacy restrictions,

on data generated from the clinical trial, and diminished protection of intellectual property in some countries. Operations in foreign

jurisdictions are subject to additional risks, including dependence on third party manufacturers or suppliers outside of the United States,

as well as political and economic risks relevant to foreign countries.

45

Risks Related to Government and Regulatory Matters

The regulatory approval

processes of the FDA and other comparable foreign regulatory authorities are lengthy, time-consuming and unpredictable. We may not be

able to commercialize, or may be delayed in commercializing, our product candidates, and our ability to generate revenue may be materially

impaired if we are not able to obtain, or if there are delays in obtaining, required regulatory approvals for our product candidates.

The lengthy regulatory approval

process as well as the unpredictability of clinical trial results may result in our failing to obtain or be delayed in obtaining approval

to market our product candidates, which would significantly harm our business, results of operations and prospects. Before obtaining regulatory

approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical studies

and clinical trials that our product candidates are both safe and effective for each targeted indication. In addition, 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. Of the large number of drugs in development, only a small percentage successfully complete the

FDA or foreign regulatory approval processes and are commercialized. Approval may never be obtained and the approval process can vary

substantially based upon a variety of factors, including the type, complexity and novelty of the product candidates involved. While there

are several approved products and product candidates in later stages of development for the treatment of PsO and for the treatment of

HS, our programs incorporate advanced antibody engineering to optimize the half-life and formulation of antibodies, and to date, no such

antibody has been approved by the FDA for the treatment of PsO or for HS.

The FDA and comparable foreign

regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that

our data are insufficient for approval and require additional preclinical, clinical, or other data. Our product candidates could be delayed

in receiving, or fail to receive, regulatory approval for many reasons, including: the failure to demonstrate that a product candidate’s

benefits outweigh safety risks; regulatory authorities may disagree with our interpretation of clinical data or the data collected may

not be acceptable or sufficient to support submission; or the results may not meet the level of statistical significance required for

approval by the relevant regulatory authorities or otherwise considered insufficient by the FDA or comparable foreign regulatory authorities.

Regulatory authorities may require the addition of labeling statements, such as a black box warning or other warnings or contraindications

that could diminish the usage of the product or otherwise limit the commercial success of the affected product.

Moreover, regulatory authorities may approve any of our product candidates

for fewer or more limited indications than we request, including failing to approve the most commercially promising indications, 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. If we are

not able to obtain, or if there are delays in obtaining, required regulatory approvals for our product candidates, we will not be able

to commercialize, or will be delayed in commercializing, our product candidates and our ability to generate revenue may be materially

impaired.

We may not be able

to meet requirements for the chemistry, manufacturing, and control of our programs.

In order to receive approval of our products by the FDA and comparable

foreign regulatory authorities, we must show that we and our CMO partners are able to characterize, control and manufacture our drug products

safely and in accordance with regulatory requirements. This includes, among other things, manufacturing the active ingredient, developing

an acceptable formulation, manufacturing the drug product, performing tests to adequately characterize the formulated product, documenting

a repeatable manufacturing process in larger quantities as we move forward in our development programs, and demonstrating that our drug

products meet stability requirements. As noted above, we may deliver our product candidates via a drug delivery device, which also requires

us to meet certain chemistry, manufacturing and control requirements set forth by the FDA and other foreign regulatory authorities. Meeting

these chemistry, manufacturing and control requirements is a complex task that requires specialized expertise. If we are not able to meet

the chemistry, manufacturing, and control requirements, we may not be successful in our clinical trials or getting our product candidates

approved by regulatory authorities.

Our product candidates

for which we intend to seek approval as biologics may face competition sooner than anticipated.

The Patient Protection and Affordable Care Act, as amended by the Healthcare

and Education Reconciliation Act (the “ACA”), includes a subtitle called the Biologics Price Competition and Innovation Act

(the “BPCIA”), which created an abbreviated approval pathway for biological products that are biosimilar to or interchangeable

with an FDA-licensed reference biological product. Under the BPCIA, an application for a highly similar or “biosimilar”

product may not be submitted to the FDA until four years following the date that the reference product was first approved by the

FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until 12 years from the date on

which the reference product was first approved. During this 12-year period of exclusivity, another company may still market

a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own

preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity, and potency of their

product.

46

We believe that any of our

product candidates approved as biologics under a BLA should qualify for the 12-year period of exclusivity. However, there is

a risk that this exclusivity could be shortened due to congressional action or otherwise, or that the FDA will not consider our product

candidates to be reference products for competing products, potentially creating the opportunity for competition sooner than anticipated.

Other aspects of the BPCIA, some of which may impact the BPCIA exclusivity provisions, have also been the subject of recent litigation.

Moreover, the extent to which a biosimilar, once approved, will be substituted for any reference products in a way that is similar to

traditional generic substitution for non-biological products is not yet clear, and will depend on a number of marketplace and

regulatory factors that are still developing.

Even if our product

candidates receive regulatory approval, we will remain subject to extensive ongoing regulatory obligations and continued regulatory review,

which could result in restrictions on the use of the products, significant additional expenses, and penalties if we fail to comply with

regulatory requirements or experience unanticipated issues with our product candidates.

If any of our product candidates

receive regulatory approval, we will remain subject to ongoing regulatory requirements imposed by the FDA and comparable foreign authorities.

These requirements may include post-approval safety and pharmacovigilance reporting, product labeling restrictions or warnings, risk management

requirements such as a Risk Evaluation and Mitigation Strategy (“REMS”), post-marketing commitments or additional studies

to further assess safety, efficacy, or real-world use, as well as compliance with applicable manufacturing and quality system regulations.

Regulatory authorities may also conduct periodic inspections of our

manufacturing facilities or those of our third-party manufacturers and may take enforcement action if we or such third parties fail to

comply with applicable regulatory requirements or if safety, quality, or manufacturing issues arise. Such actions could include labeling

changes, restrictions on use or distribution, clinical holds, recalls or withdrawal of products, warning or untitled letters, fines, penalties,

or other enforcement measures. Failure to comply with these ongoing obligations, or the emergence of unexpected safety or quality issues

after commercialization, could result in significant additional costs, limit our ability to commercialize, and may materially harm our

business.

Disruptions or changes at the FDA, the SEC and other government agencies

and regulatory authorities 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 operation of our business may rely, which could negatively impact our business.

The ability of the FDA to

review regulatory filings and our ability to commence clinical trials 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, statutory, regulatory and policy changes,

disruptions caused by government shutdowns and public health crises. There have been mass layoffs of federal government employees since

the start of the Trump administration in January 2025, the full impact of which is unclear at this time. 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 our operations

may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid

and unpredictable. Furthermore, the Trump administration has made and is expected to continue to make changes in the leadership of various

U.S. federal regulatory agencies and changes to U.S. federal government policy that have led to, in some cases, legal challenges and uncertainty

around the funding, functioning and policy priorities of the U.S. federal regulatory agencies, including the FDA.

Disruptions at the FDA and other agencies or comparable foreign regulatory

authorities, may also slow the time necessary for the review and approval of applications for clinical trial or marketing authorization,

which would adversely affect our business. For example, in recent years, the U.S. government has experienced shut downs and funding lapses,

during which time certain regulatory agencies, such as the FDA and the SEC, furloughed critical employees and stopped critical activities.

Additionally, action by the Trump administration to limit federal agency budgets or personnel may result in reductions to the FDA’s

budget, employees, and operations, which may lead to slower response times and longer review periods, potentially affecting our ability

to progress development of our product candidates or obtain regulatory approval for our product candidates. If a prolonged government

shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could

have a material adverse effect on our business. Further, government shutdowns could impact our ability to access the public markets and

obtain necessary capital in order to properly capitalize and continue our operations.

47

We are unable to predict

the extent to which the Trump administration may impose or seek to impose leadership or policy changes at the FDA or changes to rules

and policies impacting our business and operations. It is unclear how these executive actions or other potential actions by the federal

government will impact the FDA or other regulatory authorities that oversee our business. Government proposals to reduce or eliminate

budgetary deficits may include reduced allocations to the FDA and other related government agencies. These budgetary pressures may reduce

the FDA’s ability to perform its responsibilities, which could result in delays in our clinical trial timelines. If a significant

reduction in the FDA’s workforce occurs, the FDA’s budget is significantly reduced or a prolonged government shutdown occurs,

it could significantly impact the ability of the FDA to timely review and process our regulatory submissions or take other actions critical

to the development or manufacturing of our product candidates, which could have a material adverse effect on our business.

If a prolonged government

shutdown occurs, or if global health concerns prevent the FDA or other regulatory authorities from conducting their regular inspections,

reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely

review and process our regulatory submissions, which could have a material adverse effect on our business.

We may face difficulties

from legislative or regulatory reform measures.

We may be faced with additional

or changing regulatory and governmental regulations that could prevent, limit or delay regulatory approval of our product candidates.

We 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. For example, the Trump administration has discussed several changes to the

reach and oversight of the FDA, which could affect its relationship with the pharmaceutical industry, transparency in decision making

and ultimately the cost and availability of prescription drugs. If we are slow or unable to adapt to changes in existing requirements

or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval

that we may have obtained and we may not achieve or sustain profitability.

The price of pharmaceuticals

has been a topic of considerable public discussion that could lead to price controls or other price-limiting strategies by third-party

payors that have the effect of lowering payment and reimbursement rates for drugs or otherwise making the commercialization of pharmaceuticals

less profitable. Many federal and state legislatures have considered, and adopted, healthcare policies intended to curb rising healthcare

costs, such as the Inflation Reduction Act (“IRA”). These cost-containment measures may include, among other measures: requirements

for pharmaceutical companies to negotiate prescription drug prices with government healthcare programs; controls on government-funded

reimbursement for drugs; new or increased requirements to pay prescription drug rebates to government healthcare programs, including if

drug prices increase at a higher rate than inflation; controls on healthcare providers; challenges to or limits on the pricing of drugs,

including pricing controls or limits or prohibitions on reimbursement for specific products through other means; requirements to try less

expensive products or generics before a more expensive branded product; and public funding for cost effectiveness research, which may

be used by government and private third-party payors to make coverage and payment decisions. Political, economic and regulatory developments

may further complicate developments in healthcare systems and pharmaceutical drug pricing. These developments could, for example, impact

our potential licensing agreements as commercial and collaborative partners may also consider the impact of these pressures on their licensing

strategies.

Any new laws or regulations

that have the effect of imposing additional costs or regulatory burden on pharmaceutical manufacturers, or otherwise negatively affect

the industry, could adversely affect our ability to successfully commercialize our product candidates. The implementation of any price

controls, caps on prescription drugs or price transparency requirements could adversely affect our business, operating results and financial

condition.

Our business operations

and current and future arrangements with investigators, healthcare professionals, consultants, third-party payors, patient organizations

and customers will be subject to applicable healthcare regulatory laws, including conflicts of interest rules, which could expose us to

penalties.

Our business operations and current and future arrangements with investigators,

healthcare professionals, consultants, third-party payors, patient organizations and customers may expose us to broadly applicable

healthcare laws and regulations, including conflict of interest laws. These laws may constrain the business or financial arrangements and

relationships through which we conduct our operations.

Principal investigators for

our clinical trials may serve as scientific advisors or consultants to us or may be affiliated with our other service providers, including

CROs or site management organizations, and from time to time may receive cash compensation in connection with such services. If these

relationships and any related compensation result in perceived or actual conflicts of interest, the integrity of the data generated at

the applicable clinical trial site or in the applicable trial may be questioned or jeopardized.

Ensuring that our internal operations and future business arrangements

with third parties comply with applicable healthcare laws and regulations will involve costs and management attention. If our operations

are found to be in violation of any of these laws or any other governmental laws and regulations that may apply to it, we may be subject

to significant penalties, including civil, criminal and administrative penalties, damages, fines, exclusion from government-funded healthcare

programs, integrity oversight, and reporting obligations to resolve allegations of non-compliance, disgorgement, individual

imprisonment, contractual damages, reputational harm, diminished profits, and the curtailment or restructuring of our operations. Further,

defending against any such actions can be costly and time-consuming and may require significant personnel resources. Therefore, even

if we are successful in defending against any such actions that may be brought against us, our business may be impaired.

48

Even if we are able

to commercialize any product candidates, we may be subject to unfavorable pricing regulations and/or third-party coverage and reimbursement

policies, and we may not be able to offer such product candidates at competitive prices, which could seriously harm our business.

We intend to seek approval to market our product candidates in the

United States and in selected foreign jurisdictions, and we will be subject to rules and regulations in those jurisdictions where

we obtain approval. Our ability to successfully commercialize any product candidates that we may develop will depend in part on the extent

to which reimbursement for these product candidates and related treatments will be available from government health administration authorities,

private health insurers, and other organizations. In some jurisdictions, government authorities and other third-party payors decide

which medications they will pay for and establish reimbursement levels, and have attempted to control costs by limiting coverage and the

amount of reimbursement for particular medications. These entities may create preferential access policies for a competitor’s product,

including a branded or generic/biosimilar product, over our products in an attempt to reduce their costs, which may reduce our commercial

opportunity. Additionally, if any of our product candidates are approved and we are found to have improperly promoted off-label uses

of those product candidates, we may become subject to significant liability, which could materially adversely affect our business and

financial condition.

We are subject to U.S. and

certain foreign export and import controls, sanctions, embargoes, anti-corruption laws, and anti-money laundering laws and regulations.

We can face criminal liability and other serious consequences for violations, which can harm our business.

We are subject to export control and import laws and regulations, including

the U.S. Export Administration Regulations, U.S. Customs regulations, various economic and trade sanctions regulations administered

by the U.S. Treasury Department’s Office of Foreign Assets Controls, the U.S. Foreign Corrupt Practices Act of 1977,

as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the

U.S. Physician Payments Sunshine Act, and other state and national anti-bribery and anti-money laundering laws in the countries

in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents,

contractors, and other collaborators from authorizing, promising, offering, or providing, directly or indirectly, improper payments or

anything else of value to or from recipients in the public or private sector. We may engage third parties to sell our products outside

the United States, to conduct clinical trials, and/or to obtain necessary permits, licenses, patent registrations, and other regulatory

approvals. We have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals,

universities, and other organizations. We can be held liable for the corrupt or other illegal activities of our employees, agents, contractors,

and other collaborators, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws

and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or

import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences.

Governments outside

the United States tend to impose strict price controls, which may adversely affect our revenue, if any.

In some countries, particularly member states of the EU (“EU

Member States”), the pricing of prescription drugs is subject to governmental control. In these countries, pricing negotiations

with governmental authorities can take considerable time after receipt of marketing approval for a therapeutic. In addition, there can

be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment

measures. Political, economic, and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue

after reimbursement has been obtained. Reference pricing used by various EU Member States and parallel distribution, or arbitrage between low-priced and

high-priced EU Member States, can further reduce prices. To obtain coverage and reimbursement or pricing approvals in some countries,

we or current or future collaborators may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of

our product candidates to other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of discounts

by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication

and other countries. If reimbursement of any product candidate approved for marketing is unavailable or limited in scope or amount, or

if pricing is set at unsatisfactory levels, our business, financial condition, results of operations, or prospects could be materially

and adversely affected. If the UK or EU Member States were to significantly alter their regulations affecting the pricing of prescription

pharmaceuticals, we could face significant new costs.
