Overview

We are a late-stage biotechnology company focused on developing and commercializing transformative treatments for patients with serious immunological diseases. Our lead product candidate, atacicept, a self-administered fusion protein that blocks both B lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL), is currently being evaluated for the treatment of immunoglobulin A nephropathy (IgAN) in the Phase 2b ORIGIN clinical trial, which has completed enrollment. We expect to announce topline results in the first quarter of 2023. If the data from this trial are supportive, we plan to initiate a pivotal Phase 3 clinical trial in 2023. Based on positive feedback from the U.S. Food and Drug Administration's (FDA) review of clinical results of a Phase 2 clinical trial of atacicept in high disease activity patients with systemic lupus erythematosus (SLE), we have initiated the Phase 3 COMPASS clinical trial of atacicept in lupus nephritis (LN), a severe manifestation of SLE. In December 2021, we obtained worldwide, exclusive development and commercial rights from Amplyx, a wholly owned subsidiary of Pfizer, to MAU868, a potentially first-in-class monoclonal antibody to treat BK virus (BKV) infections. We believe MAU868 is the only clinical-stage neutralizing monoclonal antibody that is directed against BKV, a polyoma virus that can have devastating consequences in certain settings such as kidney transplant and hematopoietic stem cell transplant. An interim analysis of Phase 2 data in BK viremia among kidney transplant recipients presented in June 2022 showed MAU868 to be well tolerated and demonstrated a clinically significant reduction of virologic activity. Based on additional feedback from the FDA, which we expect to obtain in early 2023, we are planning to initiate a Phase 2b or Phase 3 clinical trial in 2023. We believe that our current pipeline programs leverage the deep expertise of our team and have strong commercial synergies. We currently hold global rights to all of our pipeline programs.

Since our inception, we have devoted substantially all of our resources to our research and development efforts, pre-clinical studies and clinical trials, establishing and maintaining our intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for these operations

We do not have any product candidates approved for commercial sale, and we have not generated any revenue from product sales. Our ability to generate revenue sufficient to achieve profitability, if ever, will depend on the successful development and eventual commercialization of one or more of our product candidates, which we expect, if they ever occur, will take a number of years. We also do not own or operate, and currently have no plans to establish, any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of our product candidates for nonclinical and clinical testing, as well as for commercial manufacturing if any of our product candidates obtain marketing approval. We believe that this strategy allows us to maintain a more efficient infrastructure by eliminating the need for us to invest in our own manufacturing facilities, equipment, and personnel while also enabling us to focus our expertise and resources on the development of our product candidates.

To date, we have funded our operations primarily through proceeds from the sale of shares of our Class A common stock, redeemable convertible preferred stock, debt financing and convertible promissory notes. As of September 30, 2022, we had $114.4 million in cash, cash equivalents and marketable securities, compared to $79.7 million as of December 31, 2021. In May 2021, we completed our initial public offering (IPO) and issued 5,002,500 shares of Class A common stock for net proceeds of approximately $48.4 million, after deducting underwriting discounts and commissions, and offering related expenses. In February 2022, we



                                       25

--------------------------------------------------------------------------------

completed a follow-on public offering and issued 5,742,026 shares of Class A common stock for net proceeds of approximately $80.0 million, after deducting underwriting discounts and commissions, and offering related expenses. We believe, based on our current operating plan, that our cash, cash equivalents and marketable securities as of September 30, 2022, will be sufficient to fund our operations for at least the next 12 months from the date of this Quarterly Report on Form 10-Q.

We have incurred significant operating losses since the commencement of our operations. Our net losses were $24.7 million and $7.6 million for the three months ended September 30, 2022 and 2021, respectively, and $56.6 million and $15.8 million for the nine months ended September 30, 2022 and 2021, respectively, and we expect to incur significant and increasing losses for the foreseeable future as we continue to advance our product candidates, atacicept and MAU868, to commercialization. Our net losses may fluctuate significantly from period to period, depending on the timing of expenditures on our research and development activities. As of September 30, 2022, we had an accumulated deficit of $180.7 million, compared to $124.1 million as of December 31, 2021. Our primary use of cash is to fund operating expenses, which comprise research and development and general and administrative expenditures. Cash used to fund operating expenses depends on the timing of when we pay these expenses, as reflected in the changes in our working capital balances.

We expect to continue to incur net operating losses for at least the next several years, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase. We expect our expenses and capital requirements will increase significantly in connection with our ongoing activities as we:

continue our ongoing and planned research and development of our product candidates, atacicept, for the treatment of IgAN and LN, and MAU868 for the treatment of BK viremia;

conduct clinical trials and nonclinical studies for atacicept and MAU868;

seek regulatory approvals for any product candidates that successfully complete clinical trials;

continue to scale up external manufacturing capacity with the aim of securing sufficient quantities to meet our capacity requirements for clinical trials and potential commercialization;

establish a sales, marketing and distribution infrastructure to commercialize any approved product candidates and related additional commercial manufacturing costs;

develop, maintain, expand, protect and enforce our intellectual property portfolio, including patents, trade secrets and know how;

attract, hire and retain additional clinical, scientific, quality control, and manufacturing management and administrative personnel;

expand leased office facilities;

add clinical, operational, financial and management information systems and personnel, including personnel to support our product development and planned future commercialization efforts; and

incur additional legal, accounting, investor relations and other expenses associated with operating as a public company.

We also expect to increase the size of our administrative function to support the growth of our business. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenditures on other research and development activities.

We will require substantial additional funding to develop our product candidates and support our continuing operations. Until such time that we can generate significant revenue from product sales or other sources, if ever, we expect to finance our operations through the sale of equity, debt financings, or other capital sources, which could include income from collaborations, strategic partnerships, or marketing, distribution, licensing or other strategic arrangements with third parties, or from grants. We may be unable to raise additional funds or to enter into such agreements or arrangements on favorable terms, or at all. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic and otherwise. Our failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations or financial condition, including requiring us to have to delay, reduce or eliminate our product development or future commercialization efforts. Insufficient liquidity may also require us to relinquish rights to product candidates at an earlier stage of development or on less favorable terms than we would otherwise choose. The amount and timing of our future funding requirements will depend on many factors, including the pace and results of our development efforts. We cannot provide assurance that we will ever be profitable or generate positive cash flow from operating activities.

COVID-19 Pandemic and other Geopolitical and Macroeconomic Events

Since it was reported to have surfaced in December 2019, a novel strain of coronavirus (COVID-19) has spread across the world and has been declared a pandemic by the World Health Organization. Efforts to contain the spread of COVID-19 have intensified and governments around the world, including in the United States, Europe and Asia, have implemented travel restrictions, social distancing requirements, stay-at-home orders and have delayed the commencement of non-COVID-19-related clinical trials, among other restrictions. While vaccines have become widely available in certain countries, and businesses and economies have reopened, the status of global economic recovery remains uncertain and unpredictable, and will continue to be affected by developments in the pandemic including any subsequent outbreaks or new variant strains of the COVID-19 virus which may require re-closures or other preventative measures. As a result, the current COVID-19 pandemic has presented a substantial public health and economic challenge around the world and is affecting our employees, patients, communities and business operations, as well as contributing to significant volatility and negative pressure on the U.S. economy and in financial markets.

As a result of the outbreak, many companies have experienced disruptions in their operations and in markets served. To date, we have initiated some and may take additional temporary precautionary measures intended to help ensure our employees' well-being and minimize business disruption. For the safety of our employees and their families, we have reduced the amount of time we expect our employees to spend onsite in our facilities. Certain of our third-party service providers have also experienced shutdowns or other business disruptions. We are continuing to assess the impact of the COVID-19 pandemic on our current and future business and operations, including our expenses, clinical trials and other development timelines, as well as on our industry and the healthcare system.

As a result of the COVID-19 pandemic, or similar pandemics and outbreaks, we have and may in the future experience severe disruptions, including:

interruption of or delays in receiving products and supplies from the third parties on which we rely, due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems;

limitations on our business operations by the local, state, or federal government;

business disruptions caused by workplace, laboratory and office closures and an increased reliance on employees working from home, travel limitations, cybersecurity and data accessibility limits, or communication or mass transit disruptions; and

limitations on employee resources that would otherwise be focused on the conduct of our activities, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people.

Additionally, financial markets around the world experienced volatility following the recent invasion of Ukraine by Russia. In response to the invasion, the United States, United Kingdom and European Union (EU), along with others, imposed significant new sanctions and export controls against Russia, Russian banks and certain Russian individuals and may implement additional sanctions or take further punitive actions in the future. The full economic and social impact of the sanctions imposed on Russia (as well as possible future punitive measures that may be implemented), as well as the counter measures imposed by Russia, in addition to the ongoing military conflict between Ukraine and Russia and related sanctions, which could conceivably expand into the surrounding region, remains uncertain; however, both the conflict and related sanctions have resulted and could continue to result in disruptions to trade, commerce, pricing stability, credit availability, supply chain continuity and reduced access to liquidity in both Europe and globally, and have introduced significant uncertainty into global markets. As a result, our business and results of operations may be adversely affected by the ongoing conflict between Ukraine and Russia and related sanctions, particularly to the extent it escalates to involve additional countries, further economic sanctions or wider military conflict.

Although we did not experience significant financial effects to our business operations as a result of macroeconomic events, such as the COVID-19 pandemic or the ongoing Russia-Ukraine conflict, during the nine months ended September 30, 2022, there may be potential effects to our business in the future that are highly uncertain and difficult to predict, such as disruptions or restrictions in our supply chain, disruptions or restrictions to our employees' ability to travel, disruptions to or delays in ongoing clinical trials, third-party manufacturing, continued increases in inflation and interest rates, and changes our ability to raise capital and conduct business development activities. The effects of these macroeconomic events are highly uncertain, subject to change, and may present uncertain challenges for us.

Research and Development Expenses

Research and development expenses represent a substantial portion of our operating expenses. Our research and development expenses consist primarily of direct and indirect expenses incurred in connection with the research and development of our product candidates. Direct expenses include costs incurred under agreements with third parties, including contract research and manufacturing organizations and consultants directly related to our research and development of product candidates, laboratory supplies and costs of lab studies, and license and milestone fees incurred as a result of our contractual obligations for our development candidates. Indirect expenses include employee compensation and other personnel-related expenses, including stock-based compensation, facilities and depreciation related to buildings and equipment used for research and development personnel and activities and other expenses. From October 2020 until December 2021, we have been engaged in the development of atacicept as our sole product candidate. In December 2021, we entered into the Amplyx Agreement and acquired our second product candidate, MAU868.

Research and development expenses are recorded as expense in the period in which the related activities occurred, and payments we make prior to the receipt of goods or services to be used in research and development efforts are deferred as prepaid expenses until the goods or services are received and used. We accrue expenses for contract research and development as the related services are performed by monitoring the status of specified activities and billings received from our external service providers. These expenses are accrued based on estimates and are adjusted as actual expenses become known. The cost incurred in obtaining technology licenses, including initial and subsequent milestone payments incurred under our licensing agreements, are recorded as expense in the period in which they are incurred, as the licensed technology, method or process has no alternative future uses other than for our research and development activities. Where contingent milestone payments are due to third parties under license or other agreements, the milestone payment obligations are recognized as expense when achievement of the contingent milestone is probable, which is generally upon achievement of the milestone.

The following table summarizes our research and development expenses incurred during the respective periods.

Research and development expenses increased by $16.1 million, or 452%, to $19.7 million in the three months ended September 30, 2022, from $3.6 million in the three months ended September 30, 2021. The increase was primarily due to progressing clinical development of atacicept in IgAN and LN, including expenses incurred in manufacturing clinical supply for current and future clinical trials, and development milestone expenses incurred for MAU868. Clinical trial expenses increased by $3.3 million due to patient screening and enrollment and clinical site activity in ORIGIN and startup activity for the COMPASS trial. Contract drug manufacturing increased by $5.2 million primarily due to expenses incurred to enable contract drug manufacturers to produce atacicept drug substance and drug product for clinical trials and potential commercialization. License and milestone expense of $3.7 million was incurred during the three months ended September 30, 2022 as a result of an amendment to the Exclusive License Agreement between Amplyx Pharmaceuticals Inc. and Novartis International Pharmaceutical AG that was assigned to us in December 2021 in connection with our purchase of MAU868 and certain related assets from Amplyx. Compensation and related benefits for research and development increased by $2.0 million due to increased headcount to support clinical development of atacicept and MAU868 during the current period.

We expect our research and development expenses to increase in future periods as we initiate additional clinical sites and enroll patients in the Phase 3 COMPASS clinical trial, initiate a Phase 3 clinical trial of atacicept in IgAN, and plan and initiate a Phase 2b or Phase 3 clinical trial of MAU868.

General and Administrative Expenses

General and administrative expenses consist primarily of compensation and personnel-related expenses, including stock-based compensation, for our personnel in executive management, legal, finance, human resources, and other administrative functions. General and administrative expenses also include professional fees paid for accounting, auditing, legal, tax and consulting services, and other general overhead costs to support our operations. General and administrative expenses are recorded as expense in the period they are incurred, and payments we make prior to the receipt of goods or services to be used for general and administrative purposes efforts are deferred as prepaid expenses until the goods or services are received and used.

General and administrative expenses increased by $1.9 million, or 52%, to $5.6 million in the three months ended September 30, 2022, from $3.7 million in the three months ended September 30, 2021, due primarily to increases of $0.9 million of payroll and related expenses including stock-based compensation, $0.4 million of rent expense recorded in the 2022 period due to separate presentation of sublease income in the statement of operations and comprehensive loss associated with the adoption of new accounting guidance for leases, and an increase of $0.4 million in legal expenses for corporate and intellectual property matters.

Total other income increased by $0.9 million to $0.6 million of other income in the three months ended September 30, 2022, from other expense of $0.4 million in the three months ended September 30, 2021, due to an increase of $0.6 million in interest income from greater balances of funds available for investment and higher yields on marketable securities held in the current period and other income of $0.3 million from sublease income recognized due to the adoption of new accounting guidance for leases.

Liquidity and Capital Resources

To date, we have funded our operations primarily through proceeds from the sale of shares of our Class A common stock, redeemable convertible preferred stock, debt financing and convertible notes. From our inception through September 30, 2022, we have raised aggregate net cash proceeds of $275.0 million from the issuance and sale of redeemable convertible preferred stock, convertible notes, and Class A common stock, and proceeds from our Loan Agreement with Oxford Finance LLC (Oxford). Since the date of our incorporation, we have not generated any revenue from product sales and have incurred substantial operating losses and negative cash flows from operations.

We use our cash to fund operations, primarily to fund our research and development efforts, clinical trials, establishing and maintaining our intellectual property portfolio, hiring personnel, raising capital, and providing general and administrative support for



                                       29

--------------------------------------------------------------------------------

these operations. Cash used to fund operating expenses is affected by the timing of when we pay these expenses, as reflected in the change in our outstanding accounts payable, accrued expenses and prepaid assets.

We anticipate that we will continue to incur net losses for the foreseeable future as we continue research and development activities of atacicept and MAU868, hire additional staff, including clinical, operational, administrative and management personnel, and incur additional expenses associated with operating as a public company. We expect to incur significant expenses and operating losses for the foreseeable future as we advance our clinical development activities and our product candidate portfolio. We expect that our research and development and general and administrative costs will increase substantially as a result of our acquisition of MAU868, including in connection with conducting additional clinical trials and clinical trials for our research programs and product candidates, contracting with third parties to support nonclinical studies and clinical trials, expanding our intellectual property portfolio, and providing general and administrative support for our operations. As a result, we will need additional capital to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing arrangements, or other sources.

On May 18, 2021, we completed our IPO. In connection with our IPO, we issued and sold 5,002,500 shares of Class A common stock, including 652,500 shares associated with the full exercise on May 20, 2021 of the underwriters' option to purchase additional shares, at a price to the public of $11.00 per share, resulting in net proceeds to us of approximately $48.4 million, after deducting underwriting discounts and commissions and offering related expenses payable by us. All shares issued and sold were registered pursuant to a registration statement on Form S-1, as amended (File No. 333-255492), declared effective by the SEC on May 13, 2021.

In December 2021, we entered into the Amplyx Agreement, pursuant to which we paid $5.0 million to Amplyx to purchase assets relating to MAU868. In September 2022, we entered into an amendment to the Novartis License to modify the terms of potential development milestone payments. Pursuant to this amendment, we issued 283,034 shares of Class A common stock to Novartis in exchange for a reduction of $7.0 million in contingent future development milestone, including the $2.0 million contingent milestone obligation we accrued in December 2021. The value of the shares issued was $5.7 million based on the closing market value of our Class A common stock as of the effective date of the amendment, and as a result of the amendment we recognized $3.7 million of research and development expense in the three and nine months ended September 30, 2022.

In December 2021, we entered into the Loan Agreement with Oxford, which was amended in November 2022, pursuant to which we may borrow up to an aggregate maximum principal amount of $50.0 million, of which $5.0 million was funded on December 17, 2021, and $20.0 million was funded on November 4, 2022, and the balance of which is available to be drawn between January 3, 2022, and December 29, 2023. See "-Loan and security agreement" below.

On February 14, 2022, we completed our follow-on public offering. In connection with our follow-on public offering, we issued and sold 5,742,026 shares of Class A common stock, including 748,959 shares associated with the full exercise of the underwriters' option to purchase additional shares, at a price to the public of $15.00 per share, resulting in net proceeds to us of approximately $80.0 million, after deducting underwriting discounts and commissions and offering related expenses payable by us.

In June 2022, we filed a shelf registration statement on Form S-3 (the Shelf Registration) with the Securities and Exchange Commission (the SEC), which permits the offering, issuance, and sale of up to a maximum aggregate offering price of $400.0 million of our common stock, preferred stock, debt securities and warrants. In connection with the filing of the Shelf Registration, we entered into a sales agreement with Cowen and Company, LLC (Cowen) as sales agent, pursuant to which we may issue and sell shares of our Class A common stock for an aggregate maximum offering price of $150.0 million of the maximum aggregate offering price of $400.0 million under an at-the-market offering program (the 2022 ATM). We agreed to pay Cowen up to 3% of gross proceeds for the Class A common stock sold through the 2022 ATM. As of September 30, 2022, no shares of Class A common stock have been issued or sold under the 2022 ATM.

As of September 30, 2022, we had $114.4 million of cash, cash equivalents and marketable securities, compared to $79.7 million as of December 31, 2021. We believe, based on our current operating plan, that our cash, cash equivalents and marketable securities as of September 30, 2022, will be sufficient to fund our operations for at least the next 12 months from the date of this Quarterly Report on Form 10-Q.

Loan and security agreement

On December 17, 2021, we entered into a loan and security agreement, as amended on November 4, 2022 (the Loan Agreement) with Oxford, a Delaware limited liability company, as lender (Lender) and collateral agent. The Loan Agreement provides for a term loan (the Loan) in an aggregate maximum principal amount of $50.0 million, of which $5.0 million was funded on December 17, 2021, $20.0 million was funded on November 4, 2022, and the balance of which is available to be drawn between January 3, 2022 and December 29, 2023. The Loan is available in minimum draws of $5.0 million, entirely at our option and not contingent upon the completion of clinical, regulatory, financial or other related milestones.

The final maturity date of the Loan is December 17, 2026, which may, upon achieving either (i) positive Phase 2b clinical trial data of atacicept in IgAN or (ii) positive pivotal trial data of atacicept in LN, at our option, be extended by 12 months (the Maturity Date Extension). We are required to make monthly interest-only payments for 48 months (extended to 60 months if the Maturity Date Extension is exercised) followed by full amortization through maturity.

--------------------------------------------------------------------------------

Initially, through December 30, 2021, the Loan incurred interest at a per annum rate of 8.254%. Thereafter, the Loan bears interest at a floating per annum rate (based on the actual number of days elapsed divided by a year of 360 days) equal to the greater of (i) 8.25% and (ii) the sum of (a) 1-Month CME Term SOFR as reported by CME Group Benchmark Administration Limited on the last business day of the month that immediately precedes the month in which the interest will accrue, and (b) 8.25%.

We are permitted to prepay the Loan in full or in part at any time upon 10 business days' written notice to the Lender, subject to the applicable Prepayment Fee (as defined below). Upon the earliest to occur of the maturity date, acceleration of the Loan or prepayment of the Loan, we are required to make a final payment equal to 5.0% (7.0% if the Maturity Date Extension is exercised) of the aggregate principal amount of the Loan (the Final Fee). Any prepayments of the Loan, whether mandatory or voluntary, must include an amount equal to the sum of (a) the portion of the outstanding principal of the Loan being prepaid plus accrued and unpaid interest thereon through the prepayment date, (b) the Final Fee, (c) the Lender's expenses and all other obligations that are due and payable to the Lender, and (d) a prepayment fee of (i) 3.0% of the portion of the Loan being prepaid if the repayment is on or before the first anniversary of the funding date of such term loan or (ii) 2.0% of the portion of the Loan being prepaid if the repayment is after the first anniversary of the funding date but on or before the second anniversary of the funding date of such term loan (the Prepayment Fee). There is no Prepayment Fee for any prepayments occurring after the second anniversary of the funding date of such term loan.

Our obligations under the Loan Agreement are secured by a security interest in all of our assets, other than our intellectual property, which is subject to a negative pledge. The Loan Agreement does not contain any financial related covenants. Included in the Loan Agreement are customary representations and covenants that, subject to exceptions, restrict our ability to, among other things: declare dividends or redeem or repurchase equity interests; incur additional liens; make loans and investments; incur additional indebtedness; engage in mergers, acquisitions and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to our existing business.

Upon the occurrence of an event of default, a default interest rate of an additional 5.0% may be applied to the outstanding loan balances, and the Lender may declare all outstanding obligations immediately due and payable and take such other actions as set forth in the Loan Agreement. Events of default under the Loan Agreement include customary events of default, including, but not limited to: (i) failure to (a) make any payment of principal or interest on its due date, or (b) pay any other obligations within three business days after such obligations are due and payable; (ii) failure to perform any obligation under specified covenants; (iii) the occurrence of a material adverse change; (iv) we or any of our subsidiaries being or becoming insolvent, beginning an insolvency proceeding, or becoming subject to an insolvency proceeding that is not dismissed or stayed within 45 days; (v) a default under any agreement with a third party resulting in a right by such third party to accelerate the maturity of any indebtedness in an amount in excess of $500,000 or that could reasonably be expected to have a material adverse change; (vi) the rendering of judgments, orders, or decrees for the payment of money in an amount, individually or in the aggregate, of at least $500,000 that remain unsatisfied, unvacated, or unstayed for a period of 10 days after the entry thereof; (vii) revocation, rescission, suspension or adverse modification of any governmental approval, or non-renewal of a governmental approval in the ordinary course for a full term, that could reasonably be expected to result in a material adverse change; and (viii) failure of a lien created under the Loan Agreement or any other loan document to constitute a valid and perfected lien on any of the collateral purported to be secured thereby, subject to no prior or equal lien, other than permitted liens.

Emerging growth company status

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). We have elected to use the extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that (i) we are no longer an emerging growth company or (ii) we affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

We will remain an emerging growth company under the JOBS Act until the earliest of (i) the last day of our first fiscal year in which we have total annual gross revenue of $1.235 billion or more, (ii) the date on which we have issued more than $1.0 billion of non-convertible debt instruments during the previous three fiscal years, (iii) the date on which we are deemed a "large accelerated filer" under the rules of the SEC with at least $700.0 million of outstanding equity securities held by non-affiliates, or (iv) December 31, 2026.

Critical Accounting Policies and Significant Judgments and Estimates

The discussion and analysis of our financial condition and results of operations is based on our unaudited condensed financial statements, which have been prepared in accordance with United States generally accepted accounting principles (GAAP). The preparation of these unaudited condensed 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 the financial statements, as well



                                       32

--------------------------------------------------------------------------------

as expenses incurred during the reporting periods. Our estimates are based on our 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.

Our critical accounting policies are described in the section titled "Management's Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies, Significant Judgments and Use of Estimates" in our Annual Report and the notes to our unaudited condensed financial statements appearing elsewhere in this Quarterly Report on Form 10-Q. During the nine months ended September 30, 2022, there were no material changes to our critical accounting policies from those discussed in our Annual Report.
