ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following

discussion and analysis of our financial condition and results of operations in conjunction with our financial statements and notes thereto

appearing elsewhere in this Annual Report. In addition to historical financial information, the following discussion and analysis contains

forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results could differ materially from those anticipated

by these forward-looking statements as a result of many factors. We discuss factors that we believe could cause or contribute to these

differences below and elsewhere in this Form 10-K, including those set forth under “Risk Factors” and “Forward-Looking

Statements.”

Overview

We are a clinical-stage immunology

company focused on developing drugs that may reprogram the patient’s innate immune system to treat disease. We believe this may

be done by targeting cells of the innate immune system that cause acute and chronic inflammation and are involved in immune dysfunction

associated with chronic diseases such as cancer and neurodegenerative diseases. The Company’s drugs are in clinical trials and have

not been approved by a regulatory authority. The Company has two therapeutic platforms – a dominant-negative TNF platform (“DN-TNF”,

“XProTM”, “XPro1595TM” or “pegipanermin”) and a Natural Killer (“NK”,

or “INKmuneTM”) platform. The DN-TNF platform neutralizes soluble TNF (“sTNF”) without affecting trans-membrane

TNF (“tmTNF”) or TNF receptors -TNFR1 and TNFR2. This unique biologic mechanism differentiates the DN-TNF drugs from currently

approved non-selective TNF inhibitors that inhibit both sTNF and tmTNF. Protecting the function of tmTNF and TNF receptors while neutralizing

the function of sTNF is a potent anti-inflammatory strategy that does not cause immunosuppression or demyelination which occur in the

currently approved non-selective TNF inhibitors. Currently approved non-selective TNF inhibitors treat autoimmune disease, but are contraindicated

in patients with infection, cancer and neurologic diseases because they increase the risk of infection, cancer and demyelinating neurologic

diseases, respectively; all the safety problems are due to off-target effects on inhibiting tmTNF. The NK platform targets the dysfunctional

natural killer cells in patients with cancer. NK cells are part of the normal immunologic response to cancer with important roles in immunosurveillance

to prevent cancer and in preventing relapse by eliminating residual disease. Residual disease is the cancer left behind after therapy

is finished. Residual disease can grow to cause relapse. The mechanism by which INKmune improves the ability of the patient’s NK

cells to kill their cancer is complex. The NK cells of cancer patients lose the ability to bind and kill cancer cells. A measure of NK

cell binding to cancer cells is avidity. The higher the avidity, the greater the bond between the NK cell to cancer cell and thus the

greater NK killing of cancer cells. INKmune increase NK avidity and further improves mitochondrial function and upregulates nutrient receptors.

These metabolic changes may help the INKmune primed NK cell to function in the hostile tumor microenvironment and persist much longer.

These mechanisms improve the ability of INKmune primed NK cells to overcome the immune evasion of the patient’s cancer cells. We

believe INKmune is best used to eliminate residual disease after the patient has completed other cancer therapies. Both the DN-TNF platform

and the INKmune platform can be used to treat multiple diseases. The DN-TNF platform will be used as an immunotherapy for the treatment

of cancer and neurodegenerative disease. INKmune is being developed to treat NK sensitive hematologic malignancies and solid tumors.

60

We believe our DN-TNF platform

can be used as a cancer therapy to reduce resistance in immunotherapy and as a CNS (“central nervous system”) therapy to target

glial activation to prevent progression of Alzheimer’s disease (“AD”), and to target neuroinflammation in treatment

resistant depression (“TRD”) and as a drug to prevent muscle degeneration, prevent fibrosis and promote muscle regeneration

in Duchene muscular dystrophy (DMD). The drug is named differently for the oncology and CNS indications; INB03TM or XProTM,

respectively, but it is the same drug product. For DMD, the company is exploring DN-TNF compounds that is optimized for the treatment

of DMD. This novel compound has the same mechanism of action but has novel IP protection. In each case, we believe neutralizing sTNF is

a cornerstone to the treatment of these diseases. As an immunotherapy for cancer, we are using INB03 to neutralize sTNF produced by HER2+

trastuzumab resistant breast cancers to reverse resistance to targeted therapy. sTNF produced by the tumor causes an up-regulation of

MUC4 express causing steric hindrance of trastuzumab binding to the HER receptor on HER2+ breast cancer cells. Without binding, trastuzumab

based therapies are not effective. Neutralizing sTNF reverses MUC4 expression converting a trastuzumab resistant breast cancer cell into

a trastuzumab sensitive breast cancer cell. In addition, INB03 changes the immunobiology of the tumor microenvironment by decreasing the

number of immunosuppressive myeloid cells, both myeloid derived suppressor cells and tumor active macrophages, and increasing the number

of cytotoxic lymphocytes and phagocytic macrophages in the TME. The Company has completed an open label dose escalation trial in cancer

patients with metastatic solid tumors that have failed multiple lines of therapy. The trial informs the design of the Phase II trial by

demonstrating that INB03 was safe and well tolerated, defined the dose of INB03 to carry into Phase II trials, and demonstrated a pharmacodynamic

end-point. A Phase II trial is planned in patients with advanced MUC4+ expressing cancer.

Likewise, we believe the DN-TNF

platform can be used to treat selected neurodegenerative diseases by modifying the brain microenvironment (“BME”). The Company

believes the core pathology of cognitive decline is a combination of neurodegeneration and synaptic dysfunction. Neurodegeneration is

nerve cell death that may include demyelination. Synaptic dysfunction means the connections between nerve cells stop working efficiently

and may decrease in number. The combination of neurodegeneration and synaptic dysfunction causes cognitive decline and behavioral changes

associated with Alzheimer’s disease (AD. XPro completed a Phase I trial treating patients with Alzheimer’s disease that was

partially funded by a Part-the-Clouds Award from the Alzheimer’s Association. We believe XPro targets activated microglia and astrocytes

of the brain that produce sTNF that promotes nerve cell loss and synaptic dysfunction, key elements in the development of dementia. In

animal models, elimination of sTNF prevents nerve cell dysfunction and reverses synaptic pruning. The Phase I trial in patients with biomarkers

of inflammation with AD has been completed. The open label, dose escalation trial was designed to demonstrate that XPro can safely decrease

neuroinflammation in patients with ADi. The endpoints of the trial are measures of neuroinflammation and neurodegeneration in blood and

cerebral spinal fluid by measuring changes in inflammatory cytokine levels in the CNS and using MRI-DTI to measure white matter free water.

White matter free water; a validated measure of neuroinflammation in the brain. XPro, at the 1mg/kg/week dose decreased inflammatory cytokines

in the CSF and decreased white matter free water in the brain demonstrating that XPro can decrease neuroinflammation in patients with

AD. We also studied downstream benefits of decreasing neuroinflammation by measuring changes in the CSF proteome and quantifying changes

in novel white matter MRI biomarkers. XPro significantly decreases biomarkers of neurodegeneration as measured by changes in the

CSF proteome including neurofilament light chain, phospho Tau 217 and VILIP-1; decreases of 84%, 46% and 91% respectively after 3 months

of therapy. Three months of XPro therapy improved measures of synaptic function, as measured in the CSF proteome including a 222% increase

in Contactin 2 and a 56% decrease neurogranin, changes that contribute to improved synaptic function.

The successful completion

of the Phase I trial in AD has informed the design of a blinded randomized, placebo controlled Phase II trials in patients with early

ADi. Early ADi includes patients with AD and MCI who have at least one biomarker of inflammation (ADi and MCI2 respectively).

The early ADi trial is a blinded randomized trial to test if treatment of early AD patients with neuroinflammation with XPro will affect

cognitive decline. The Phase II trial in early ADi has six important elements. Two hundred patients are being enrolled in a 2:1 ratio

(XPro vs placebo). The patients will receive 1mg/kg/week as a subcutaneous injection for six months. An enrichment strategy identical

to the successful strategy used in the Phase I trial will be used to ensure patients have neuroinflammation. Patients will need to have

one or more enrichment criteria: elevated blood level of at least one of C-reactive protein, hemoglobin A1c, erythrocyte sedimentation

and at least one allele of ApoE4. The primary end-point will be Early/mild Alzheimer’s Cognitive Composite (“EMACC”),

a validated cognitive measure that is more sensitive than traditional end-points used in many studies of patients with early AD. The

trial is open in Australia and Canada and will open in the US pending the lift of a clinical hold by the US FDA. All patients will be

offered to stay on therapy for at least 12 months in an extension trial. Clinical and biomarker data will be collected during the extension

trial.

61

Effective therapy for TRD

is a large unmet need. Twenty percent of patients with a Major Depressive Disorder have TRD. Once third of TRD patients have peripheral

biomarkers to inflammation (elevated CRP). This is a large patient population. The role of TNF and anti-TNF therapeutics was explored

in a small open label clinical trial by Prof. Andrew Miller, MD of Emory University demonstrated the patients have elevated TNF levels

and treatment with infliximab treated their depression (Miller, 2011). The Company received a $2.9M USD award from the National Institute

of Mental Health (“NIMH”) to treat TRD with XPro. The blinded, randomized Phase II trial will use biomarkers of peripheral

inflammation to select patients with TRD for enrollment. Patients will be treated for 6 weeks. Primary end-points include both clinical

and neuroimaging measures. The final trial design is ongoing and discussions with the FDA are not complete. The Company anticipates receiving

authorization to initiate the clinical trial once the pending clinical hold is lifted.

We believe that INKmune improves

the ability of the patient’s own NK cells to attack their tumor. INKmune interacts with the patient’s NK cells to convert

them from inert resting NK cells into memory-like NK cells that kill the patient’s cancer cells. INKmune is a replication incompetent

proprietary cell line that is given to the patient after determining that i) the patient has adequate NK cells in their circulation and

ii) those NK cells are functional when exposed to INKmune in vitro. INKmune is designed to be given to patients after their immune system

has recovered after cytotoxic chemotherapy to target the residual disease the remains after treatment with cytotoxic therapy. We believe

INKmune can be used to treat numerous hematologic malignancies and solid tumors including leukemia, multiple myeloma, lymphoma, lung,

ovary, breast, renal and prostate cancer. The Company has initiated a Phase I trial using INKmune to treat patients with high risk MDS/AML,

a form of leukemia. One patient has been treated in the Phase I trial for MDS and three patients have been treated compassionately in

AML. In the four patients, INKmune therapy is safe, produces memory-like NK cells that kill cancer in vitro, promotes development of cancer

killing memory-like NK cells that can be found in the patient’s circulation of 4 months. The Company will continue to enroll patients

in the Phase I trial. The Company intends to initiate a separate Phase I/2 trial of INKmune in a solid tumor during 2023.

Since

our inception in 2015, we have devoted substantially all of our resources to the discovery and development of our product candidates,

including clinical trials and preclinical studies as well as general and administrative support for these operations. To date, we have

generated no significant revenue. We have incurred net losses in each year since our inception and, as of December 31, 2022, we had an

accumulated deficit of approximately $91.0 million. Our net losses were $27,299,000 and $30,340,000 for the years ended December 31,

2022 and 2021, respectively. Substantially all of our net losses resulted from costs incurred in connection with our research and development

programs and from general and administrative costs associated with our operations, including stock-based compensation.

The

Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The extent of the impact of the COVID-19 pandemic

on the Company’s business is highly uncertain and difficult to predict. Also, economies worldwide have also been negatively impacted

by the COVID-19 pandemic, however policymakers around the globe have responded with fiscal policy actions to support the healthcare industry

and economy as a whole. The magnitude and overall effectiveness of these actions remain uncertain.

In addition, the Company’s clinical trials have been affected

by and may continue to be affected by the COVID-19 pandemic. Clinical site initiation and patient enrollment have and may continue to

be delayed due to prioritization of hospital resources toward the COVID-19 pandemic. Some patients have not, and others may not be able

to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. Similarly, the ability

to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to

COVID-19, may adversely impact the Company’s clinical trial operations.

The

severity of the impact of the COVID-19 pandemic on the Company’s business will depend on a number of factors, including, but not

limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company’s service providers,

suppliers, contract research organizations (“CROs”) and the Company’s clinical trials, all of which are uncertain and

cannot be predicted. As of the date of issuance of Company’s financial statements, the extent to which the COVID-19 pandemic may

materially impact the Company’s financial condition, liquidity or results of operations is uncertain.

63

As a company with less than $1.07 billion in revenue

during our last fiscal year, we qualify as an “emerging growth company” under the JOBS Act. As an emerging growth company,

we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies.

These provisions include:

● reduced disclosure about our executive compensation arrangements;

We have elected to take advantage of the above-referenced

exemptions and we may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth

company. We would cease to be an emerging growth company if we have more than $1.07 billion in annual revenues, we have more than $700

million in market value of our stock held by non-affiliates, or we issue more than $1 billion of non-convertible debt over a three-year

period. We may choose to take advantage of some but not all of these reduced burdens.

Components of Operating Results

Operating Expenses

Research and Development

Research and development expense consists of expenses

incurred while performing research and development activities to discover and develop our product candidates. This includes conducting

preclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for product candidates.

We recognize research and development expenses as they are incurred. Our research and development expense primarily consist of:

● clinical trial and regulatory-related costs;

● manufacturing and testing costs and related supplies and materials; and

We typically use our employee, consultant and

infrastructure resources across our development programs. We track outsourced development costs by product candidate or development program,

but we do not allocate personnel costs, other internal costs or external consultant costs to specific product candidates or development

programs.

We participate, through our wholly-owned subsidiary

in Australia, in the Australian research and development tax incentive program, such that a percentage of our qualifying research and

development expenditures are reimbursed by the Australian government, and such incentives are reflected as a reduction of research and

development expense. The Australian research and development tax incentive is recognized when there is reasonable assurance that the incentive

will be received, the relevant expenditure has been incurred and the amount of the consideration can be reliably measured.

64

We participate, through our wholly-owned subsidiary in the United Kingdom,

in the research and development program provided by the United Kingdom tax relief program, such that a percentage of our qualifying research

and development expenditures are reimbursed by the United Kingdom government, and such incentives are reflected as a reduction of research

and development expense. The United Kingdom has recently enacted certain changes to the research and development program which will limit

the research and development tax incentive available to the Company. The United Kingdom research and development tax incentive is recognized

when there is reasonable assurance that the incentive will be received, the relevant expenditure has been incurred and the amount of the

consideration can be reliably measured.

Substantially all of our research and development

expenses to date have been incurred in connection with our current and future product candidates. We expect our research and development

expenses to increase significantly for the foreseeable future as we advance an increased number of our product candidates through clinical

development, including the conduct of our planned clinical trials and manufacturing drug to be used in those clinical trials. The process

of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. The successful development of product

candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining

development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product

candidates.

The costs of clinical trials may vary significantly

over the life of a project owing to, but not limited to, the following:

● per patient trial costs;

● the number of sites included in the clinical trials;

● the countries in which the clinical trials are conducted;

● the length of time required to enroll eligible patients;

● the number of patients that participate in the clinical trials;

● the number of doses that patients receive;

● the cost of comparative agents used in clinical trials;

● the drop-out or discontinuation rates of patients;

● the duration of patient follow-up;

● the efficacy and safety profile of the product candidate; and

We do not expect any of our product candidates

to be commercially available for at least the next several years, if ever. We expect to continue to incur significant expenses and increasing

operating losses for the foreseeable future, which may fluctuate significantly from quarter-to-quarter and year-to-year. We anticipate

that our expenses will increase substantially as we:

● potentially seek regulatory approval for our product candidates;

65

● seek to discover and develop additional product candidates;

● seek to comply with regulatory standards and laws;

● maintain, leverage and expand our intellectual property portfolio;

General and Administrative Expenses

General and administrative expenses consist principally

of payroll and personnel expenses, including stock-based compensation; professional fees for legal, consulting, accounting and tax services;

insurance, overhead, including rent and utilities; and other general operating expenses not otherwise classified as research and development

expenses.

Other income, net

Other expense consists primarily of interest expense incurred on debt,

partially offset by interest income from a money market investment.

Critical Accounting Policies and Significant

Judgments and Estimates

This management’s discussion and analysis

of our financial condition and results of operations is based on our financial statements, which we have prepared in accordance with accounting

principles generally accepted in the United States. The preparation of our financial statements requires us to make estimates and assumptions

that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our

financial statements, as well as the reported revenues and expenses during the reported periods. We evaluate these estimates and judgments

on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under

the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are

not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

In-Process Research and Development

The Company evaluates the carrying value of indefinite-lived

intangible assets, which consists of in-process research and development (“IPR&D”), on an annual basis or more frequently

when indicators of impairment exist. An impairment of indefinite-lived intangible assets would occur if the fair value of the intangible

asset is less than the carrying value. Intangible assets with finite lives are tested for impairment when events or changes in circumstances

indicate that the carrying amount of such assets may not be recoverable. If these facts and circumstances exist, the Company assesses

for recovery by comparing the carrying values of the assets with their future undiscounted net cash flows. Significant management judgment

is required in the forecast of future operating results that are used in the preparation of expected undiscounted cash flows.

66

IPR&D assets are considered to be indefinite-lived

until the completion or abandonment of the associated research and development projects. During the period the assets are considered indefinite-lived,

they are tested for impairment. If the related project is terminated or abandoned, the Company may have a full or partial impairment related

to the IPR&D assets, calculated as the excess of their carrying value over fair value. The valuation process is very complex and requires

significant input and judgment using internal and external sources with respect to the Company’s future revenue and expense growth

rates, changes in working capital use, the selection of an appropriate discount rate, and other assumptions and estimates.

Research and Development (“R&D”)

R&D expenses consist primarily of costs related

to clinical studies and outside services, personnel expenses, and other R&D expenses. Clinical studies and outside services costs

relate primarily to services performed by clinical research organizations and related clinical or development manufacturing costs, materials

and supplies, filing fees, regulatory support, and other third-party fees. Personnel expenses relate primarily to salaries, benefits and

share-based compensation. R&D expenditures are charged to operations as incurred.

We recognize R&D tax credits receivable from the United Kingdom

and Australian government for spending on R&D as a reduction of R&D expenses.

Stock-Based Compensation

We measure and recognize compensation

expense for all stock-based awards granted to service providers, employees, and directors based on the estimated fair value of the

award on the grant date. We calculate the estimated fair value of stock options on the date of grant using the Black-Scholes

option-pricing model, which is impacted by the fair value of our common stock, as well as changes in assumptions regarding a number

of highly complex and subjective variables. These variables include, but are not limited to, the market value of common stock on the

grant date, the expected dividend yield, the expected term of the awards, the risk-free interest rates and the expected common stock

price volatility over the term of the option awards. The expected volatility is based on the historical volatility of a few

unrelated public companies within our industry over the most recent period commensurate with the estimated expected term of our

stock options as we have insufficient historical information regarding the volatility of the share price of our common stock. The

risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield in effect at

the time of grant. We have never declared or paid dividends and have no plans to do so in the foreseeable future.

We recognize the fair value of stock options on

a straight-line basis over the period during which a service provider is required to provide services in exchange for the award (generally

the vesting period). We account for forfeitures as they occur.

Off-Balance Sheet Arrangements

During the periods presented, we did not have

any off-balance sheet arrangements as defined under SEC rules.

Licensing and Collaboration Agreements

We anticipate that in-licensing, out-licensing

and strategic collaborations will become an integral part of our operations, providing the company with opportunities to leverage our

partners’ expertise and capabilities to further expand the potential of our technologies, product candidates and revenue streams.

Xencor

In October 2017, we licensed INB03 (also known

as XPro) from Xencor. This exclusive, global, unrestricted license came with considerable know-how, intellectual property, pre-clinical

data, regulatory documentation and product stocks. Currently, we are focused on the immune-oncology uses of this unique asset. In the

future, we may develop the asset in a wide variety of therapeutic areas, with a variety of delivery techniques by ourselves or in conjunction

with partners.

Results of Operations

Comparison of the Years Ended December 31,

2022 and December 31, 2021

Year Ended

Revenues

During 2022 and 2021, the Company sold MSC’s to one and three

customers, respectively, and recognized $374,000 and $181,000 of revenues, respectively.

General and Administrative

General and administrative expenses were $9.3 million for the year

ended December 31, 2022, compared to $8.8 million for the year ended December 31, 2021. The increase in general and administrative expenses

is largely due to higher compensation, including stock-based compensation ($1.5 million higher during the year ended December 31, 2022)

and higher rent expense and right of use asset impairment ($0.2 million higher during the year ended December 31, 2022), partially offset

by lower consulting expense ($1.5 million lower during the year ended December 31, 2022).

Research and Development

Research and development expenses decreased to

$17.1 million for the year ended December 31, 2022 from $20.5 million for the year ended December 31, 2021. The decrease in research

and development expenses during the year ended December 31, 2022 compared to 2021 is mainly due to the Company incurring $4.6 million

of lower manufacturing costs in connection with producing its DN-TNF product and also due to incurring $2.6 million of lower expenses

on the COVID-19 clinical trial, partially offset by the Company’s compensation (including stock-based compensation) which

was $1.8 million higher in 2022 compared to 2021.

Other Expense, net

Other expense, net increased

to $1.3 million during the year ending December 31, 2022, compared to $1.2 million during the year ending December 31, 2021. The increase

in other expense is due to higher interest expense on the Company’s debt ($1.0 million higher), partially offset by $0.7 million

higher interest income from money market investments.

68

Liquidity and Capital Resources

Liquidity is the ability of a company to generate

funds to support its current and future operations, satisfy its obligations and otherwise operate on an ongoing basis.

We incurred a net loss

of $27,299,000 and $30,340,000 for the years ended December 31, 2022 and 2021, respectively. Net cash used in operating activities

was $22,686,000 and $28,504,000 for the years ended December 31, 2022 and 2021, respectively. Since inception, we have funded our

operations primarily with proceeds from the sales of our common stock and from the receipts of grants. As of December 31, 2022, we

had cash and cash equivalents of $52,153,000. We anticipate that operating losses and net cash used in operating activities will

increase over the next few years as we advance our products under development.

Our primary uses of capital are, and we expect

will continue to be, third-party clinical and preclinical research and development services, costs incurred to manufacture our drugs under

development, compensation and related expenses, legal, patent and other regulatory expenses and general overhead costs. We believe our

use of CROs provides us with flexibility in managing our spending.

The Company incurs the majority of its research and development expenses

in Australia and the United Kingdom. Fluctuations in the rate of exchange between the United States dollar and the pound sterling

as well as the Australian dollar could adversely affect our financial results, including our expenses as well as assets and liabilities.

We currently do not hedge foreign currencies but will continue to assess whether that strategy is appropriate. As of December 31, 2022,

the cash balance held by our foreign subsidiaries with currencies other than the United States dollar was approximately $0.1 million.

As of December 31, 2022, the Company had an accumulated deficit of

$91.0 million and working capital of $53.8 million. Losses have principally occurred as a result of the substantial resources required

for research and development of the Company’s products which included the general and administrative expenses associated with its

organization and product development, as well as the lack of sources of material revenues until such time as the Company’s products

are commercialized. As of December 31, 2022, we had cash and cash equivalents of $52.2 million. We believe our cash and cash equivalents

will be sufficient to fund our operations for at least the next 12 months following the filing date of this Annual Report on Form 10-K.

Registered Direct

Offering

During

July 2021, the Company completed a registered direct offering whereby the Company sold 1,818,182 shares of its common stock to investors

for net proceeds of $36.9 million.

ATM Sales Agreements

During the year ended

December 31, 2021, we issued and sold 1,439,480 shares of common stock at an average price of $20.17 per share under the 2020 ATM agreement.

The aggregate net proceeds were approximately $28.4 million after BTIG’s commission and other offering expenses. As of December

31, 2021, sales of our common stock pursuant to the 2020 ATM have been completed.

During March 2021, the Company entered into the 2021 ATM agreement

with BTIG, as sales agent, to establish an ATM offering of up to $45 million of common stock. During the year ended December 31, 2021,

the Company sold 713,192 shares at an average price per share of $21.73 for net proceeds of approximately $14.9 million under the 2021

ATM agreement.

Term Loan

On

June 10, 2021, we entered into a Loan and Security Agreement with SVB and an affiliate of SVB, providing for a $15.0 million term loan.

The Term Loan also provides for us to request an additional $5.0 million term loan from the Lenders, which may be granted or denied at

the sole discretion of the Lenders. The Term Loan provides for an annual interest rate equal to the greater of (i) the prime rate then

in effect as reported in The Wall Street Journal plus 4.50% and (ii) 7.75% and also includes a final payment fee equal to 6.5%

of the original principal amount borrowed payable on the earlier of the repayment of the loan in full and the maturity date. The Company

used the proceeds of the term loan to fund the cash consideration for the Option Cancellation Agreement with Xencor.

69

Cash Flows

The following table provides information regarding our cash flows for

the years ended December 31, 2022 and 2021:

Year Ended December 31,

Net cash used in operating activities $ (22,686 ) $ (28,504 )

Net cash used in investing activities - (15,000 )

Net cash provided by financing activities 729 96,357

Impact on cash from foreign currency translation (700 ) (10 )

Net(decrease) increase in cash and cash equivalents $ (22,657 ) $ 52,843

Net Cash Used in Operating Activities

Our cash used in operating activities was primarily

driven by our net loss.

Operating activities

used $22.7 million of cash for the year ended December 31, 2022, primarily resulting from our net loss of $27.3 million, a net cash

outflow of $2.9 million for changes in our net operating assets and liabilities, and non-cash stock-based compensation charges of

$7.1 million. The change in our net operating assets and liabilities was primarily due to an increase in research and development

tax credit receivable of $3.2 million and an increase in prepaid expenses and other current assets of $1.7 million, partially offset

by an increase in accounts payable and accrued liabilities of $1.5 million.

Operating activities

used $28.5 million of cash for the year ended December 31, 2021, primarily resulting from our net loss of $30.3 million, a net cash

outflow of $3.1 million for changes in our net operating assets and liabilities, and non-cash stock-based compensation charges of

$4.8 million. The change in our net operating assets and liabilities was primarily due to an increase in research and development

tax credit receivable of $3.2 million and an increase in prepaid expenses and other current assets of $2.1 million, partially offset

by an increase in accounts payable and accrued liabilities of $2.2 million.

Opinion on the Financial Statements

We have audited the accompanying consolidated

balance sheets of INmune Bio, Inc. (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of

operations and comprehensive loss, changes in stockholders’ equity and cash flows for each of the two years in the period ended

December 31, 2022, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial

statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results

of its operations and its cash flows for each of the two years in the period ended December 31, 2022, in conformity with accounting principles

generally accepted in the United States of America

Basis for Opinion

These financial statements are the responsibility

of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We

are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are

required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and

regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the

standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial

statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged

to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding

of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal

control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess

the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond

to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.

Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating

the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

INMUNE BIO INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – ORGANIZATION AND BASIS

OF PRESENTATION

Organization and Business Overview

INmune Bio, Inc. (the “Company” or

“INmune Bio”) was organized in the State of Nevada on September 25, 2015 and is a clinical stage biotechnology pharmaceutical

company focused on developing and commercializing its product candidates to treat diseases where the innate immune system is not functioning

normally and contributing to the patient’s disease. INmune Bio has two product platforms. The DN-TNF product platform utilizes

dominant-negative technology to selectively neutralize soluble TNF, a key driver of innate immune dysfunction and mechanistic target of

many diseases. DN-TNF is currently being developed for Alzheimer’s and treatment resistant depression (“XPro”) and cancer (“INB03”)

and an out-licensing strategy for Duchenne’s Muscular Dystrophy (“DMD”). The Natural Killer Cell Priming Platform includes

INKmune aimed at priming the patient’s NK cells to eliminate minimal residual disease in patients with cancer. INmune Bio’s

product platforms utilize a precision medicine approach for the treatment of a wide variety of hematologic malignancies, solid tumors

and chronic inflammation.

Basis of Presentation and Principles of

Consolidation

The accompanying consolidated financial statements

of the Company have been prepared in accordance with Generally Accepted Accounting Principles (“US GAAP”) in the United States

of America and the rules of the Securities and Exchange Commission (“SEC”).

The consolidated financial statements herein have

been prepared in accordance with US GAAP and include the accounts of INmune Bio, its wholly-owned UK subsidiary, and its wholly-owned

Australia subsidiary (collectively, the “Company”). All significant intercompany accounts and transactions have been eliminated.

NOTE 2 – LIQUIDITY

As of December

31, 2022, the Company had an accumulated deficit of $91,014,000 and experienced losses since its inception. The Company had cash,

cash equivalents of $52,153,000 as of December 31, 2022 and has not generated positive cash flows from operations. To date, the Company

has funded its operations primarily through the sale of its common stock. Although it is difficult to predict the Company’s liquidity

requirements, as of December 31, 2022, and based upon the Company’s current operating plan, the Company believes that it will have

sufficient cash to meet its projected operating requirements for at least the next 12 months following the filing date of this Annual

Report on Form 10-K based on the balance of cash available as of December 31, 2022.

Management

expects operating losses to continue for the foreseeable future. There can be no assurance that the Company will ever earn revenues or

achieve profitability, or if achieved, that they will be sustained on a continuing basis. In addition, the manufacturing, clinical and

preclinical development activities as well as the commercialization of the Company’s products, if approved, will require significant

additional financing. The Company may be unable to secure such financing when needed, or if available, such financings may be under terms

that are unfavorable to the Company or the current stockholders. If the Company is unable to raise additional funds when needed, it may

be required to delay, reduce the scope of, or eliminate development programs, which may adversely affect its business and operations.

F-7

NOTE 3 – SUMMARY OF SIGNIFICANT

ACCOUNTING POLICIES

Use of Estimates

Preparing financial statements in conformity with

US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, and expenses.

Actual results and outcomes may differ from management’s estimates and assumptions.

Risks and Uncertainties

The Company is subject to risks and uncertainties

as a result of the COVID-19 pandemic. The extent of the impact of the COVID-19 pandemic on the Company’s business is highly uncertain

and difficult to predict. Also, economies worldwide have also been negatively impacted by the COVID-19 pandemic, however policymakers

around the globe have responded with fiscal policy actions to support the healthcare industry and economy as a whole. The magnitude and

overall effectiveness of these actions remain uncertain.

In addition, the Company’s clinical trials

have been affected by and may continue to be affected by the COVID-19 pandemic. Clinical site initiation and patient enrollment have and

may continue to be delayed due to prioritization of hospital resources toward the COVID-19 pandemic. Some patients have not, and others

may not be able to comply with clinical trial protocols if quarantines impede patient movement or interrupt healthcare services. Similarly,

the ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened

exposure to COVID-19, may adversely impact the Company’s clinical trial operations.

The severity of the impact of the COVID-19 pandemic

on the Company’s business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic

and the extent and severity of the impact on the Company’s service providers, suppliers, contract research organizations (“CROs”)

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 22 headings are on that chain and 0 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
