1.	The Company

Background

Xenetic Biosciences, Inc. (“Xenetic” or the “Company”), incorporated in the state of Nevada and based in Framingham, Massachusetts, is a biopharmaceutical company focused on advancing innovative immune-oncology technologies addressing hard to treat cancers. The Company’s proprietary Deoxyribonuclease (“DNase”) platform is designed to improve outcomes of existing treatments, including immunotherapies, by targeting neutrophil extracellular traps (“NETs”), which have been implicated in cancer progression and resistance to cancer treatments. Xenetic is currently focused on advancing its systemic DNase program into the clinic as an adjunctive therapy for pancreatic carcinoma and locally advanced or metastatic solid tumors. XCART^™ is the Company’s personalized Chimeric Antigen Receptor (“CAR”) T platform technology engineered to target patient specific tumor neoantigens with a demonstrated proof of mechanism in B-cell lymphomas. Additionally, Xenetic has partnered with biotechnology and pharmaceutical companies to develop its proprietary drug delivery platform, PolyXen^®, and receives royalty payments under an exclusive license arrangement in the field of blood coagulation disorders.

As used in this Quarterly Report on Form 10-Q (“Quarterly Report”), unless otherwise indicated, all references herein to “Xenetic,” the “Company,” “we” or “us” refer to Xenetic Biosciences, Inc. and its wholly-owned subsidiaries.

The Company, directly or indirectly, through its wholly-owned subsidiaries, Hesperix S.A. (“Hesperix”) and Xenetic Biosciences (U.K.) Limited (“Xenetic UK”), and the wholly-owned subsidiaries of Xenetic UK, Lipoxen Technologies Limited (“Lipoxen”), Xenetic Bioscience, Incorporated and SymbioTec, GmbH (“SymbioTec”), own various United States (“U.S.”) federal trademark registrations and applications along with unregistered trademarks and service marks, including but not limited to XCART, OncoHist™, PolyXen, ErepoXen™, and ImuXen™, which may be used throughout this Quarterly Report. All other company and product names may be trademarks of the respective companies with which they are associated.

Going Concern and Management’s Plan

Management evaluates whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. The Company has incurred substantial losses since its inception and expects to continue to incur operating losses in the near-term. These factors raise substantial doubt about its ability to continue as a going concern. The Company believes that it has access to capital resources through possible public or private equity offerings, debt financings, corporate collaborations, related party funding, or other means to continue as a going concern. The Company believes that its existing resources will be adequate to fund the Company’s operations for a period of at least twelve months from the date of these financial statements. However, the Company anticipates it may need additional capital in the long-term to pursue its business initiatives. The terms, timing and extent of any future financing will depend upon several factors, including the achievement of progress in its product development programs, its ability to identify and enter into licensing or other strategic arrangements, its continued listing on the Nasdaq Stock Market (“Nasdaq”), and factors related to financial, economic, geo-political, industry and market conditions, many of which are beyond its control. The capital markets for the biotech industry can be highly volatile, which make the terms, timing and extent of any future financing uncertain. On June 3, 2022, the Company received a written notification (the “Notice”) from the Listing Qualifications Department of Nasdaq notifying the Company that the closing bid price for its common stock had been below $1.00 for 30 consecutive business days and that the Company therefore was not in compliance with the minimum bid price requirement for continued inclusion on Nasdaq under Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”). The Notice had no immediate effect on the listing of the Company’s common stock on the Nasdaq Capital Market. On May 15, 2023, the Company effected a reduction, on a 1-for-10 basis, in its authorized common stock, par value $0.001, along with a corresponding and proportional decrease in the number of shares issued and outstanding (the “Reverse Stock Split”). On May 30, 2023, the Company received a letter from Nasdaq notifying the Company that it has regained compliance with the Bid Price Requirement as a result of the closing bid price of the Company’s common stock being at $1.00 per share or greater for the 10 consecutive business days from May 15, 2023 through May 26, 2023 and that this matter is now closed.

2.	Risks and Uncertainties

Effects of the COVID-19 Pandemic

During March 2020, a global pandemic was declared by the World Health Organization related to the outbreak of a novel strain of coronavirus, or COVID-19. The pandemic significantly affected economic conditions in the U.S., accelerating during the first half of March 2020 and continuing throughout 2021 and 2022 and into 2023, as federal, state and local governments reacted to the public health crisis with mitigation measures, creating significant uncertainties in the U.S. economy. The Company continues to evaluate the effects of the COVID-19 pandemic on its business and while there has been no significant impact to the Company’s operations to date, the Company at this time remains uncertain of the impact this event may have on the Company’s future operations. The extent to which the COVID-19 pandemic affects our business, operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict, and such uncertainty is expected to continue for some time.

Impact of the conflict in Ukraine on Operations

The short and long-term implications of Russia’s invasion of Ukraine are difficult to predict at this time. The imposition of sanctions and counter sanctions may have an adverse effect on the economic markets generally and could impact our business, financial condition, and results of operations.

3.	Summary of Significant Accounting Policies

Preparation of Interim Financial Statements

The accompanying condensed consolidated interim financial statements were prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the opinion of management, include all normal and recurring adjustments necessary to present fairly the results of the interim periods shown. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to such SEC rules and regulations. Management believes that the disclosures made are adequate to make the information presented not misleading. The results for the interim periods are not necessarily indicative of results for the full year. The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 22, 2023, and amended on April 28, 2023.

On May 15, 2023, the Company effected the Reverse Stock Split. On the effective date of the Reverse Stock Split, (i) every 10 shares of common stock were reduced to one share of common stock, with any fractional amounts rounded up to one share; (ii) the number of shares of common stock into which each outstanding warrant, restricted stock unit, or option to purchase common stock were proportionately reduced on the same basis as the common stock; (iii) the exercise price of each outstanding warrant or option to purchase common stock were proportionately increased on a 1-to-10 basis; and (iv) the number of shares of common stock into which each share of preferred stock were proportionately reduced on the same basis as the common stock. Unless otherwise indicated, all of the share numbers, share prices, and exercise prices have been adjusted in this Quarterly Report, on a retroactive basis, to reflect this 1-for-10 Reverse Stock Split.

Principles of Consolidation

The condensed consolidated financial statements of the Company include the accounts of Hesperix, Xenetic UK and Xenetic UK’s wholly owned subsidiaries: Lipoxen, Xenetic Bioscience, Incorporated, and SymbioTec. All intercompany balances and transactions have been eliminated in consolidation.

Cash and concentrations of credit risk

The Company considers all highly liquid investments with an original maturity of 90 days or less from the date of purchase to be cash equivalents. Investments with original maturities of greater than 90 days from the date of purchase but less than one year from the balance sheet date are classified as short-term investments, while investments with maturities of one year or beyond from the balance sheet date are classified as long-term investments. Management determines the appropriate classification of its cash equivalents and investment securities at the time of purchase and re-evaluates such determination as of each balance sheet date. The carrying amount of cash equivalents approximate their fair value due to the short-term nature of these instruments.

Financial instruments that potentially subject the Company to credit risk consist primarily of cash on deposit with financial institutions, the balances of which may exceed federally insured limits. The Company has not experienced any losses on such accounts, and does not believe it is exposed to any unusual credit risk beyond the normal credit risk currently associated with commercial banking relationships. Cash deposits are insured by the Federal Deposit Insurance Corporations up to $250,000. The Company maintains its primary banking relationship with one large financial institution and all cash on deposit is covered under federally insured limits.

Basic and Diluted Net Loss per Share

The Company computes basic net loss per share by dividing net loss applicable to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding during the period. The Company computes diluted net loss per share after giving consideration to the dilutive effect of stock options that are outstanding during the period, except where such non-participating securities would be anti-dilutive.

For the three and six months ended June 30, 2023 and 2022, basic and diluted net loss per share are the same for each respective period due to the Company’s net loss position. Potentially dilutive, non-participating securities have not been included in the calculations of diluted net loss per share, as their inclusion would be anti-dilutive.

Recent Accounting Standards

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The guidance modified the measurement and recognition of credit losses for most financial assets and certain other instruments. The amendment updated the guidance for measuring and recording credit losses on financial assets measured at amortized cost by replacing the “incurred loss” model with an “expected loss” model. This may result in earlier recognition of allowance for losses. The Company adopted ASU 2016-13 as of January 1, 2023 and the adoption did not have a material effect on our consolidated financial statements.

4.	Significant Strategic Collaborations

Takeda Pharmaceutical Co. Ltd. ( together with its wholly-owned subsidiaries, “Takeda”)

In October 2017, the Company granted to Takeda the right to grant a non-exclusive sublicense to certain patents related to the Company’s PolyXen technology that were previously exclusively licensed to Takeda in connection with products related to the treatment of blood and bleeding disorders. Royalty payments of approximately $0.7 million and $1.3 million were recorded as revenue by the Company during the three and six months ended June 30, 2023, respectively, and approximately $0.4 million and $0.8 million were recorded as revenue by the Company during the three and six months ended June 30, 2022, respectively. These payments are based on single digit royalties on net sales of certain covered products. The Company’s policy is to recognize royalty payments as revenue when they are reliably measurable, which is upon receipt of reports from Takeda. The Company receives these reports in the quarter subsequent to the actual sublicensee sales. At the time the revenue was received, there were no remaining performance obligations and all other revenue recognition criteria were met.

CLS Therapeutics Ltd. (“CLS”)

On April 26, 2022, the Company entered into an Exclusive Sublicense Agreement (the “Sublicense Agreement”) with CLS pursuant to which the Company received an exclusive license, under certain patent rights and know-how owned or controlled by CLS, to develop and commercialize pharmaceutical products and methods incorporating DNase enzyme for use in treatment of cancer (the “Sublicensed Products”). Under the terms of the Sublicense Agreement, the Company will have sole responsibility for, and shall use commercially reasonable efforts to, among other things, research, develop and obtain marketing approval for the Sublicensed Products in the U.S. and certain European markets, and to commercialize such Sublicensed Products in the relevant market once marketing approval is obtained.

5.	Fair Value Measurements

Accounting Standards Codification Topic 820, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 utilizes quoted market prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date. As of June 30, 2023 and December 31, 2022, the carrying amounts of the Company’s financial instruments approximates fair value due to their short maturities. There were no financial instruments classified as Level 3 in the fair value hierarchy during the three and six months ended June 30, 2023 and 2022.

6.	Stockholders’ Equity

Common Stock

On May 11, 2023, the Company filed a Certificate of Change to the Company’s Articles of Incorporation with the Secretary of State of Nevada to effect the Reverse Stock Split.

9.	Income Taxes

During the three and six months ended June 30, 2023 and 2022, there was no provision for income taxes as the Company incurred losses during both periods. Deferred tax assets and liabilities reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company records a valuation allowance against its deferred tax assets as the Company believes it is more likely than not the deferred tax assets will not be realized. The valuation allowance against deferred tax assets was approximately $39.0 million and $38.6 million as of June 30, 2023 and December 31, 2022, respectively.

As of June 30, 2023 and December 31, 2022, the Company did not record any unrecognized tax positions.

BUSINESS OVERVIEW

We are a biopharmaceutical company focused on advancing innovative immune-oncology technologies addressing hard to treat cancers. We are focused on advancing our DNase platform, which is designed to improve outcomes of existing treatments, including immunotherapies, by targeting NETs, which have been implicated in cancer progression and resistance to cancer treatments. We licensed the DNase oncology platform in April 2022 and are focusing the majority of our resources on advancing our systemic DNase program into the clinic as an adjunctive therapy for pancreatic carcinoma and locally advanced or metastatic solid tumors. We also have a personalized CAR T platform technology, XCART^™, to develop cell-based therapeutics targeting the unique B-cell receptor on the surface of an individual patient’s malignant tumor cells, for the treatment of B-cell lymphomas. Additionally, we have partnered with biotechnology and pharmaceutical companies to develop our proprietary drug delivery platform, PolyXen, and receive royalty payments under an exclusive license arrangement in the field of blood coagulation disorders.

We incorporate our patented and proprietary technologies into drug candidates currently under development with biotechnology and pharmaceutical industry collaborators to create what we believe will be the next-generation biologic drugs with improved pharmacological properties over existing therapeutics. Our drug candidates have resulted from our research activities or that of our collaborators and are in the development stage. As a result, we continue to commit a significant amount of our resources to our research and development activities and anticipate continuing to do so for the near future. To date, none of our drug candidates have received regulatory marketing authorization or approval in the U.S. by the Food and Drug Administration nor in any other countries or territories by any applicable agencies. We are receiving ongoing royalties pursuant to a license of our PolyXen technology to an industry partner. Although we hold a broad patent portfolio, the focus of our internal efforts during the three and six months ended June 30, 2023, was on the advancement of our DNase platform.

Net loss	$	(1,050,963	)	$	(2,672,190	)	$	(1,621,227	)		(60.7	)

Revenue

Revenue for the three months ended June 30, 2023 increased by approximately $0.2 million, or 56.2%, to approximately $0.7 million from approximately $0.4 million for the three months ended June 30, 2022. This increase represents an increase in royalty revenue related to our sublicense agreement with Takeda Pharmaceuticals Co. Ltd. (“Takeda”) as compared to the same period in 2022.

Research and Development Expenses

Overall, research & development (“R&D”) expenses for the three months ended June 30, 2023 decreased by $1.2 million, or 56.5% to $0.9 million from $2.1 million in the comparable quarter in 2022 primarily due to in-process research and development (“IPR&D”) expense of $1.3 million in the prior period. During the three months ended June 30, 2022, the Company expensed $1.3 million of IPR&D associated with the Company’s licensing of the DNase oncology platform. There was no similar expense in 2023. Excluding the $1.3 million of IPR&D expense from total R&D expense of approximately $2.1 million for the three months ended June 30, 2022, R&D expense for the three months ended June 30, 2023 increased by approximately $0.1 million, or 16.9%, to approximately $0.9 million from approximately $0.8 million in the comparable quarter in 2022. The table below sets forth the R&D costs incurred by us by category of expense for the quarters ended June 30, 2023 and 2022:

	Quarter Ended,
Category of Expense	June 30, 2023		June 30, 2022
IPR&D expense	$	–	$	1,305,000
Outside services and contract research organizations		731,045		598,399
Personnel costs		126,957		120,373
Share-based expense		13,778		23,128
Other		31,463		30,599
Total research and development expense	$	903,243	$	2,077,499

The increase in outside services and contract research organizations expense was primarily due to increased spending in connection with our pre-clinical development efforts associated with our DNase platform. We licensed the DNase platform in April 2022 and expect to continue to direct our efforts and resources on the development of this newly acquired technology. As a result, we suspended development of our XCART technology platform.

General and Administrative Expenses

General and administrative expenses for the three months ended June 30, 2023 decreased by approximately $0.1 million, or 7.8%, to approximately $0.9 million from approximately $1.0 million in the comparable quarter in 2022. The decrease was primarily due to a decrease in legal fees and share-based expense during the three months ended June 30, 2023 compared to the same period in 2022.

Other Income (Expense)

Other income was approximately $21,000 for the three months ended June 30, 2023 compared to approximately $1,100 of other expense for the same period in 2022. This increase in other income was primarily related to fees associated with the Pharmsynthez Loan recognized during the three months ended June 30, 2023. There were no similar fees received in the same period in 2022.

Interest Income

Interest income increased to approximately $126,000 during the three months ended June 30, 2023 as compared to approximately $16,000 for the same period in the prior year. This increase is due to higher interest rates on invested funds during the three months ended June 30, 2023 compared to the same period in 2022 as well as an increase in interest income on the Pharmsynthez Loan.

Comparison of Six Months Ended June 30, 2023 and 2022

Revenue

Revenue for the six months ended June 30, 2023 increased by $0.5 million, or 56.0%, to $1.3 million from approximately $0.8 million for the six months ended June 30, 2022. This increase represents an increase in royalty revenue related to our sublicense agreement with Takeda as compared to the same period in 2022.

Research and Development Expenses

Overall, R&D expenses for the six months ended June 30, 2023 decreased by $1.7 million, or 52.9% to $1.5 million from $3.2 million in the comparable period in 2022 primarily due to IPR&D expense of $1.3 million. During the six months ended June 30, 2022, the Company expensed $1.3 million of IPR&D associated with the Company’s licensing of the DNase oncology platform. There was no similar expense in 2023. Excluding the $1.3 million of IPR&D expense from total R&D expense of approximately $3.2 million for the six months ended June 30, 2022, R&D expenses for the six months ended June 30, 2023 decreased approximately $0.4 million, or 20.0% to $1.5 million, from approximately $1.9 million for the six months ended June 30, 2022. The table below sets forth the R&D costs incurred by us, by category of expense, for the six months ended June 30, 2023 and 2022:

	Six Months Ended,
Category of Expense	June 30, 2023		June 30, 2022
IPR&D expense	$	–	$	1,305,000
Outside services and contract research organizations		1,154,912		1,426,749
Salaries and wages		251,750		232,357
Share-based expense		27,466		42,306
Other		64,391		172,486
Total research and development expense	$	1,498,519	$	3,178,898

The decrease in outside services and contract research organizations expense was primarily due to decreased spending in connection with our XCART platform technology which was partially offset by increased costs related to our initial development efforts associated with our DNase platform. We licensed the DNase platform in April 2022 and expect to continue to direct our efforts and resources on the development of this newly acquired technology. As a result, we suspended development of our XCART technology platform. The decrease in other expense was due to lower consulting costs incurred in the first six months of 2023 compared to the same period in 2022. Consulting costs during the six months ended June 30, 2022 were related to the licensing of the DNase oncology platform from CLS.

General and Administrative Expenses

General and administrative expenses for the six months ended June 30, 2023 was $1.9 million, decreasing approximately $62,000, or 3.2%, compared to the same period in the prior year. The decrease was primarily due to a decrease in legal costs partially offset by increases in accounting and consulting costs during the six months ended June 30, 2023 as compared to the same period in 2022.

Other Income (Expense)

Other income was approximately $26,000 for the six months ended June 30, 2023 compared to approximately $1,000 of other expense for the same period in 2022. This increase in other income was primarily related to fees associated with the Pharmsynthez Loan recognized during the six months ended June 30, 2023. There were no similar fees received in the same period in 2022.

Interest Income

Interest income increased to approximately $180,000 during the six months ended June 30, 2023 as compared to approximately $42,000 for the same period in the prior year. This increase is due to higher interest rates on invested funds during the six months ended June 30, 2023 compared to the same period in 2022 as well as an increase in interest income on the Pharmsynthez Loan.

Non-GAAP Measures

In our narrative discussion of operations above, we exclude the impact of non-cash expenses from certain operating measures, which narrative discussion includes reconciliation of such adjusted financial measures to the directly comparable GAAP financial measure. We believe these adjusted operating measures may provide investors with useful information regarding our underlying performance from period to period and allow investors to better understand our results of operations. Management uses these adjusted measures when assessing the performance of the business.

Liquidity and Capital Resources

We incurred a net loss of approximately $1.9 million for the six months ended June 30, 2023. We had an accumulated deficit of approximately $191.0 million at June 30, 2023, as compared to an accumulated deficit of approximately $189.1 million at December 31, 2022. Working capital was approximately $11.2 million at June 30, 2023, and $12.6 million at December 31, 2022. During the six months ended June 30, 2023, our working capital decreased by $1.4 million primarily due to our net loss for the six months ended June 30, 2023 partially offset by proceeds from the repayment of the Pharmsynthez Loan.

Our principal source of liquidity consists of cash. At June 30, 2023, we had approximately $10.7 million in cash and $0.9 million in current liabilities. At December 31, 2022, we had approximately $13.1 million in cash and $1.1 million in current liabilities. We have historically relied upon sales of our equity securities to fund our operations.

We evaluate whether there are conditions or events, considered in the aggregate that raise substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are issued. We have incurred substantial losses since our inception, and we expect to continue to incur operating losses in the near-term. These factors raise substantial doubt about our ability to continue as a going concern. We believe that we have access to capital resources through possible public or private equity offerings, debt financings, corporate collaborations, related party funding, or other means to continue as a going concern. We believe that our existing resources will be adequate to fund our operations for a period of at least twelve months from the date of these financial statements. However, we anticipate we may need additional capital in the long-term to pursue our business initiatives. The terms, timing and extent of any future financing will depend upon several factors, including the achievement of progress in our clinical development programs, our ability to identify and enter into licensing or other strategic arrangements, our continued listing on Nasdaq, and factors related to financial, economic, geo-political, industry and market conditions, many of which are beyond our control. The capital markets for the biotech industry can be highly volatile, which make the terms, timing and extent of any future financing uncertain. On June 3, 2022, we received a written notification (the “Notice”) from the Listing Qualifications Department of Nasdaq notifying us that the closing bid price for our common stock had been below $1.00 for 30 consecutive business days and that we therefore were not in compliance with the minimum bid price requirement for continued inclusion on Nasdaq under Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”). The Notice had no immediate effect on the listing of our common stock on Nasdaq. On May 15, 2023, we effected a reduction, on a 1-for-10 basis, in our authorized common stock, par value $0.001, along with a corresponding and proportional decrease in the number of shares issued and outstanding. On May 30, 2023, the Company received a letter from Nasdaq notifying us that we had regained compliance with the Bid Price Requirement as a result of the closing bid price of our common stock being at $1.00 per share or greater for the 10 consecutive business days from May 15, 2023 through May 26, 2023 and that this matter is now closed.

On March 10, 2023, Silicon Valley Bank (“SVB”) was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (“FDIC”) as receiver. We maintained our cash primarily with SVB. On March 12, 2023, the U.S. Treasury, Federal Reserve and FDIC rolled out emergency measures to fully protect all depositors of SVB and, on March 13, 2023, we had full access to our cash on deposit with SVB. As of June 30, 2023, we have transferred our primary banking relationship to a large financial institution and all cash on deposit is covered under federally insured limits.

Cash Flows from Operating Activities

Cash flows used in operating activities for the six months ended June 30, 2023 totaled approximately $2.4 million, which was primarily due to our net loss for the period as well as advance payments made in accordance with our statement of work with Catalent, partially offset by cash received from the repayment of the Pharmsynthez Loan. Cash flows used in operating activities for the six months ended June 30, 2022 totaled approximately $2.8 million, which was primarily due to our net loss for the period, partially offset by non-cash charges associated with acquired IPR&D and share-based expense. In addition, current liabilities decreased during each of the six months ended June 30, 2023 and 2022.

Cash Flows from Investing Activities

Cash flows used in investing activities for the six months ended June 30, 2022 totaled $500,000, which represented cash paid to license the DNase oncology platform. There were no cash flows from investing activities for the six months ended June 30, 2023.

Cash Flow from Financing Activities

There were no cash flows from financing activities for the six months ended June 30, 2023 and 2022.

Contractual Obligations and Commitments

As of June 30, 2023, there were no material changes in our contractual obligations and commitments from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 22, 2023, as amended on April 28, 2023.

Off Balance Sheet Arrangements

We do not have any off-balance sheet financing arrangements that have or are reasonably likely to have a current or future material effect on our financial condition, change in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources.

Recent Accounting Standards

See Note 3 in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 22, 2023, as amended on April 28, 2023, for a discussion of recent accounting standards.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. The preparation of our condensed consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses. We base our estimates and assumptions on historical experience and other factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. The result of these evaluations forms the basis for making judgments about the carrying values of assets and liabilities and the reported amount of expenses that are not readily apparent from other sources. Because future events and their effects cannot be determined with certainty, actual results and outcomes may differ materially from our estimates, judgments and assumptions. There have been no material changes in our critical accounting estimates from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 22, 2023, as amended on April 28, 2023.

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are not required to provide the information required by this Item because we are a “smaller reporting company” (as defined in Rule 12b-2 of the Exchange Act).

ITEM 4 – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) or 15d-15(e) under the Exchange Act, as of the end of the period covered by this Quarterly Report.

Based on this evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, concluded that as of the end of the period covered by this Quarterly Report, our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report that would have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

ITEM 1 – LEGAL PROCEEDINGS

We are not currently subject to any material legal proceedings, nor, to our knowledge, is any material legal proceeding threatened against us. From time to time, we may be a party to certain legal proceedings, incidental to the normal course of our business. While the outcome of these legal proceedings cannot be predicted with certainty, we do not expect that these proceedings will have a material effect upon our financial condition or results of operations.

ITEM 1A – RISK FACTORS

There have been no material changes to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 22, 2023, as amended on April 28, 2023, other than the risks set forth below.

Risks Related to the Reverse Stock Split

The Reverse Stock Split may decrease the liquidity of our common shares.

The liquidity of our common stock may be adversely affected by the reduced number of shares outstanding after the Reverse Stock Split. In addition, the Reverse Stock Split may have increased the number of shareholders who own odd lots (less than 100 shares) of our common shares, creating the potential for such shareholders to experience an increase in the cost of selling their shares and greater difficulty effecting such sales.

We may not continue to meet the continued listing requirements of Nasdaq, which could result in a delisting of our common shares.

Our common shares are listed on Nasdaq. While we are currently in compliance, we have in the past been, and may in the future be, unable to comply with certain of the listing standards that we are required to meet to maintain the listing of our common shares on Nasdaq. For instance, on June 3, 2022, we received the Notice from the Listing Qualifications Department of Nasdaq notifying us that the closing bid price for our common stock had been below $1.00 for 30 consecutive business days and that we, therefore, were not in compliance with the Bid Price Requirement. Our Board of Directors and the Financing Committee of the Board approved the Reverse Stock Split on May 11, 2023, and on May 15, 2023, we effected the Reverse Stock Split. On May 30, 2023, we received a letter from Nasdaq notifying us that we had regained compliance with the Bid Price Requirement as a result of the closing bid price of our common stock being at $1.00 per share or greater for the 10 consecutive business days from May 15, 2023 through May 26, 2023 and that this matter was now closed.

The primary intent for the Reverse Stock Split was that the anticipated increase in the price of our common shares immediately following and resulting from a reverse stock split due to the reduction in the number of issued and outstanding common shares would help us meet the minimum bid price requirement. It cannot be assured that the Reverse Stock Split will result in any sustained proportionate increase in the market price of our common shares, which is dependent upon many factors, including the business and financial performance of the company, general market conditions, and prospects for future success, which are unrelated to the number of shares of our common shares outstanding. It is not uncommon for the market price of a company’s common shares to decline in the period following a reverse stock split. Thus, while we have regained compliance with the continued listing requirements for Nasdaq, it cannot be assured that we will continue to do so. If Nasdaq delists our common shares from trading on its exchange for failure to meet the listing standards, an investor would likely find it significantly more difficult to dispose of or obtain our shares, and our ability raise future capital through the sale of our shares could be severely limited. Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

Accounting Policies [Abstract]
Preparation of Interim Financial Statements	*Preparation of Interim Financial Statements* The accompanying condensed consolidated interim financial statements were prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the opinion of management, include all normal and recurring adjustments necessary to present fairly the results of the interim periods shown. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted pursuant to such SEC rules and regulations. Management believes that the disclosures made are adequate to make the information presented not misleading. The results for the interim periods are not necessarily indicative of results for the full year. The condensed consolidated financial statements contained herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 22, 2023, and amended on April 28, 2023. On May 15, 2023, the Company effected the Reverse Stock Split. On the effective date of the Reverse Stock Split, (i) every 10 shares of common stock were reduced to one share of common stock, with any fractional amounts rounded up to one share; (ii) the number of shares of common stock into which each outstanding warrant, restricted stock unit, or option to purchase common stock were proportionately reduced on the same basis as the common stock; (iii) the exercise price of each outstanding warrant or option to purchase common stock were proportionately increased on a 1-to-10 basis; and (iv) the number of shares of common stock into which each share of preferred stock were proportionately reduced on the same basis as the common stock. Unless otherwise indicated, all of the share numbers, share prices, and exercise prices have been adjusted in this Quarterly Report, on a retroactive basis, to reflect this 1-for-10 Reverse Stock Split.
Principles of Consolidation	*Principles of Consolidation* The condensed consolidated financial statements of the Company include the accounts of Hesperix, Xenetic UK and Xenetic UK’s wholly owned subsidiaries: Lipoxen, Xenetic Bioscience, Incorporated, and SymbioTec. All intercompany balances and transactions have been eliminated in consolidation.
Cash and concentrations of credit risk	*Cash and concentrations of credit risk* The Company considers all highly liquid investments with an original maturity of 90 days or less from the date of purchase to be cash equivalents. Investments with original maturities of greater than 90 days from the date of purchase but less than one year from the balance sheet date are classified as short-term investments, while investments with maturities of one year or beyond from the balance sheet date are classified as long-term investments. Management determines the appropriate classification of its cash equivalents and investment securities at the time of purchase and re-evaluates such determination as of each balance sheet date. The carrying amount of cash equivalents approximate their fair value due to the short-term nature of these instruments. Financial instruments that potentially subject the Company to credit risk consist primarily of cash on deposit with financial institutions, the balances of which may exceed federally insured limits. The Company has not experienced any losses on such accounts, and does not believe it is exposed to any unusual credit risk beyond the normal credit risk currently associated with commercial banking relationships. Cash deposits are insured by the Federal Deposit Insurance Corporations up to $250,000. The Company maintains its primary banking relationship with one large financial institution and all cash on deposit is covered under federally insured limits.
Basic and Diluted Net Loss per Share	*Basic and Diluted Net Loss per Share* The Company computes basic net loss per share by dividing net loss applicable to common stockholders by the weighted-average number of shares of the Company’s common stock outstanding during the period. The Company computes diluted net loss per share after giving consideration to the dilutive effect of stock options that are outstanding during the period, except where such non-participating securities would be anti-dilutive. For the three and six months ended June 30, 2023 and 2022, basic and diluted net loss per share are the same for each respective period due to the Company’s net loss position. Potentially dilutive, non-participating securities have not been included in the calculations of diluted net loss per share, as their inclusion would be anti-dilutive.
Recent Accounting Standards	*Recent Accounting Standards* In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The guidance modified the measurement and recognition of credit losses for most financial assets and certain other instruments. The amendment updated the guidance for measuring and recording credit losses on financial assets measured at amortized cost by replacing the “incurred loss” model with an “expected loss” model. This may result in earlier recognition of allowance for losses. The Company adopted ASU 2016-13 as of January 1, 2023 and the adoption did not have a material effect on our consolidated financial statements.
