BioCardia, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

(1) Summary of Business and Basis of Presentation

(a)	Description of Business
	BioCardia, Inc. (we, us, our, BioCardia or the Company), is a clinical-stage company focused on developing cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases with significant unmet medical needs. The Company’s lead therapeutic candidates are based on the CardiAMP Cell Therapy System, a platform which provides an autologous bone marrow derived cell therapy for treatment in two clinical indications: ischemic heart failure and refractory angina resulting from chronic myocardial ischemia. The Company’s second therapeutic platform is an investigational bone marrow derived allogeneic “off the shelf” Neurokinin-1 Receptor Positive mesenchymal stem cell therapy for the treatment of cardiac and pulmonary disease. To date, we have devoted substantially all our resources to research and development efforts relating to our therapeutic candidates and biotherapeutic delivery systems including conducting clinical trials, developing manufacturing and sales capabilities, in-licensing related intellectual property, providing general and administrative support for these operations and protecting our intellectual property.
	BioCardia also has three enabling device product lines: (1) the CardiAMP cell processing system; (2) the Helix biotherapeutic delivery system, or Helix; and (3) the Morph vascular access product line, or Morph. We manage our operations as a single segment for the purposes of assessing performance and making operating decisions.

(2) Significant Accounting Policies

(a)

Basis of Preparation

The accompanying condensed consolidated balance sheets, statements of operations, stockholders’ equity, and cash flows as of September 30, 2022, and for the three and nine months ended September 30, 2022 and 2021 are unaudited. The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information and on a basis consistent with the annual financial statements and, in the opinion of management, reflect all adjustments which include only normal recurring adjustments, necessary to present fairly its financial position as of September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, and cash flows for the nine months ended September 30, 2022 and 2021. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or for any other future year. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 29, 2022.

(b)	Liquidity – Going Concern
	We have incurred net losses and negative cash flows from operations since our inception and had an accumulated deficit of approximately $137.6 million as of September 30, 2022. Management expects operating losses and negative cash flows to continue through at least the next several years. We expect to incur increasing costs as we advance our trials and development activities. Therefore, absent additional funding, management believes cash and cash equivalents of approximately $6.7 million as of September 30, 2022 are not sufficient to fund the Company’s planned expenditures and meet its obligations beyond April 2023. These factors raise substantial doubt about the Company’s ability to continue as a going concern beyond one year from the date these financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
	The Company’s ability to continue as a going concern and to continue further development of its therapeutic candidates beyond April 2023, will require the Company to raise additional capital. The Company plans to raise additional capital, potentially including debt and equity arrangements, to finance its future operations. While management believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt, these plans are not entirely within its control and cannot be assessed as being probable of occurring. If adequate funds are not available, we may be required to reduce operating expenses, delay or reduce the scope of our product development programs, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize, or cease operations.

8

(c)

Use of Estimates

The preparation of the financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Significant items subject to such estimates and assumptions include share-based compensation, the useful lives of property and equipment, right-of-use assets and related liabilities, incremental borrowing rate, allowances for doubtful accounts and sales returns, clinical accruals and assumptions used for revenue recognition.

(d)	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, BioCardia Lifesciences, Inc. All intercompany accounts and transactions have been eliminated during the consolidation process.

(e)	Changes to Significant Accounting Policies
	The Company’s significant accounting policies are described in Note 2 of the notes to the consolidated financial statements included in its Annual Report on Form 10-K filed March 29, 2022 for the year ended December 31, 2021. There have been no changes to those policies.

(f)	Recent Accounting Pronouncements
	Recent accounting pronouncements issued by the Financial Accounting Standards Board (FASB), including its Emerging Issues Task Force did not or are not believed by management to have a material impact on our financial statement presentation or disclosures.

(3) Fair Value Measurement

The fair value of financial instruments reflects the amounts that we estimate to receive in connection with the sale of an asset or paid in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). We follow a fair value hierarchy that prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1 – quoted prices in active markets for identical assets and liabilities.

Level 2 – observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

9

The following table sets forth the fair value of its financial assets measured on a recurring basis as of September 30, 2022 and December 31, 2021 and indicates the fair value hierarchy utilized to determine such fair value (in thousands):

(4) Property and Equipment, Net

Property and equipment, net consisted of the following (in thousands):

	September 30,			December 31,

Property and equipment, net	$	189		$	182

Depreciation expense totaled $29,000 and $61,000 for the three and nine months ended September 30, 2022, respectively. Depreciation expense totaled $15,000 and $45,000 for the three and nine months ended September 30, 2021, respectively.

(5) Operating Lease Right-of-Use Asset, Net

Our operating lease related to a property lease for our laboratory and corporate offices expired in December 2021, and we entered into a new lease which expires in January 2027, with an option for us to extend a further 36 months after expiration. Our lease agreements do not contain any material residual guarantees or material restrictive covenants. We determine if an arrangement is a lease at inception by assessing whether it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Right-of-use (ROU) assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease does not provide an implicit rate. We used an adjusted historical incremental borrowing rate, based on the information available at the approximate lease commencement date, to determine the present value of lease payments. Variable rent expense is made up of expenses for common area maintenance and shared utilities and were not included in the determination of the present value of lease payments. We have no finance leases.

Our lease expense for the three and nine months ended September 30, 2022 was $121,000 and $362,000, respectively. Our lease expense for the three and nine months ended September 30, 2021 was $150,000 and $451,000, respectively. The cash paid under the operating lease for base rent for the three and nine months ended September 30, 2022 was $114,000 and $287,000, respectively. The cash paid under the operating lease during the three and nine months ended September 30, 2021 was $162,000 and $486,000, respectively. On September 30, 2022, the weighted average remaining lease term was 4.34 years, and the weighted average discount rate was 10.74%.

Pursuant to the Purchase Agreement, in March 2021, Lincoln Park purchased 373,832 shares of common stock, at a price of $5.35 per share, for a total gross purchase price of $2 million (the Initial Purchase) and the Company issued 80,000 shares of common stock as commitment shares, which included 5,000 commitment shares issued on a pro rata basis for the initial $2 million purchase.

As of September 30, 2022, the Company had not sold any common stock to Lincoln Park under the Purchase Agreement other than the Initial Purchase.

Cantor Fitzgerald Sales agreement - On April 12, 2022, the Company entered into a sales agreement (the Sales Agreement) with Cantor Fitzgerald & Co. (Cantor) as the sales agent, pursuant to which the Company may offer and sell, from time to time, through Cantor, shares of its common stock having an aggregate offering price of up to $10.5 million (the ATM Offering). The Company is not obligated to sell any common stock shares pursuant to the Sales Agreement. Under the terms of the Sales Agreement, the Company pays Cantor a commission of 3% of the aggregate proceeds from the sale of shares and reimburses certain legal fees.

The share-based compensation expense is recorded in research and development, and selling, general and administrative expenses based on the employee's or non-employee’s respective function. No share-based compensation was capitalized during the periods presented. Share-based compensation expense for the three and nine months ended September 30, 2022 and 2021 was recorded as follows (in thousands):

	Three months ended				Nine months ended
	September 30,				September 30,
	2022		2021		2022		2021
Research and development	$	132	$	196	$	389	$	613
Selling, general and administrative		148		241		514		624
Total share-based compensation	$	280	$	437	$	903	$	1,237

The following table summarizes the activity of stock options and related information:

	Options outstanding
	Number of shares			Weighted average exercise price		Weighted average remaining contractual term (years)		Aggregate intrinsic value (in thousands)
Balance, December 31, 2021		1,649,686		$	5.00		7.6	$	—
Stock options granted		603,953			1.54
Stock options exercised		—
Stock options forfeited		(101,796	)		3.77
Stock options expired		(3,111	)		9.55
Balance, September 30, 2022		2,148,732		$	4.08		7.7	$	248
Exercisable, September 30, 2022		1,052,136		$	5.70		6.5	$	22

Unrecognized share-based compensation for employee and nonemployee options granted through September 30, 2022 is approximately $2.3 million to be recognized over a remaining weighted average service period of 2.6 years.

12

Share-Based Compensation (RSUs)

The following summarizes the activity of non-vested RSUs:

				Weighted
				average
				grant date
	Number of			fair value
	shares			per share
Balance, December 31, 2021		200,271		$	4.13
RSUs granted		269,204			1.49
RSUs released		(328,958	)		2.72
RSUs forfeited		(87,718	)		1.49
Balance, September 30, 2022		52,799		$	3.81

RSUs vested and settled are converted into the Company’s common stock on a one-for-one basis. RSUs are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. Of the 52,799 RSUs outstanding on September 30, 2022, 50,065 RSUs are vested and have not been settled and 2,734 have not yet vested. The related compensation expense, which is based on the grant date fair value of the Company’s common stock multiplied by the number of units granted, is recognized ratably over the period during which the vesting restrictions lapse. Unrecognized share-based compensation for employee and nonemployee RSUs granted through September 30, 2022 is approximately $7,000 to be recognized over a remaining weighted average service period of 0.6 years.

(9) Net Loss per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding and fully vested restricted stock units. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. Common stock equivalents are comprised of unvested restricted stock units, warrants to purchase common stock and options outstanding under the stock option plans. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding since the effects of potentially dilutive securities are antidilutive due to the net loss position.

The following outstanding common stock equivalents were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive: 

	September 30,
	2022		2021
Stock options to purchase common stock		2,148,732		1,684,066
Unvested restricted stock units		2,734		5,468
Common stock warrants		2,424,724		2,424,724
Total		4,576,190		4,114,258

(10) Income Taxes

During the three and nine months ended September 30, 2022 and 2021, there was no income tax expense or benefit for federal or state income taxes in the accompanying condensed consolidated statements of operations due to the Company’s net loss and a full valuation allowance on the resulting deferred tax assets.

As of September 30, 2022, the Company retains a full valuation allowance on its deferred tax assets in all jurisdictions. The realization of its deferred tax assets depends primarily on its ability to generate future taxable income which is uncertain. The Company does not believe that its deferred tax assets are realizable on a more-likely-than-not basis; therefore, the net deferred tax assets have been fully offset by a valuation allowance.

(11) Related Party Transactions

On April 9, 2020, the Company entered into a Litigation Funding Agreement (the Funding Agreement) with BSLF, L.L.C. (the Funder), an entity owned and controlled by Andrew Blank, Chair of BioCardia’s board of directors, for the purpose of funding the Company’s legal proceedings and any and all claims, actions and/or proceedings relating to or arising from the case captioned Boston Scientific Corp., et al., v. BioCardia Inc., Case No. 3:19-05645-VC, U.S.D.C., N. D. Cal (the Litigation). On April 12, 2021, all parties to the Litigation entered into a confidential settlement agreement and all claims were dismissed.

In March 2022, the Company entered into settlement agreements with its litigation service providers and the Funder to terminate the Funding Agreement and conclude on all remaining matters thereunder (the Litigation Funding Settlement). Under the terms of the confidential agreements, litigation and corporate counsel provided credits and refunds of legal fees totaling $688,000, which offset the amounts owed to the Company by the Funder under the Funding Agreement, and provided up to $300,000 in future discounts on legal services. As a result of the Litigation Funding Settlement, the Company will remit the discounts, as received, to the Funder on a quarterly basis. As a result of the settlement, accounts payable was reduced by $523,000, the $562,000 other receivable due from the related party was eliminated, and a $156,000 related party payable was included in accrued expenses and other current liabilities as of December 31, 2021. The Company remitted the $156,000 related party payable to the Funder on March 17, 2022. During the three and nine months ended September 30, 2022, the Company received discounts totaling $14,000 and $61,000, respectively, with $14,000 recorded as a related party payable in accrued expenses and other current liabilities as of September 30, 2022.

(12) Contingencies and Uncertainties

Contingencies - The Company may be subject to various claims, complaints, and legal actions that arise from time to time in the normal course of business. Management is not aware of any current legal or administrative proceedings that are likely to have an adverse effect on the Company’s business, financial position, results of operations, or cash flows.

Uncertainties - The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other interim period or for any other future year, particularly in light of COVID-19 and its impact on domestic and global economies. Governmental and business reactions to the pandemic, and resulting economic disruptions, have the potential to materially impact our business and influence our business decisions. While the impact of COVID-19 did not have a material adverse effect on our financial position or results of operations for the periods presented, the Company’s future assessment of the magnitude and duration of COVID-19 and related factors, could result in material impacts to the Company’s financial statements in future reporting periods.

Overview

We are a clinical-stage company focused on developing cellular and cell-derived therapeutics for cardiovascular and pulmonary diseases with large unmet medical needs. We are committed to applying our expertise in the fields of autologous and allogeneic cell-based therapies to improve the lives of patients with cardiovascular and pulmonary conditions. Our CardiAMP cell therapy platform provides an autologous bone marrow derived cell therapy (using a patient’s own cells) for the treatment of two clinical indications: heart failure that develops after a heart attack (BCDA-01) and chronic myocardial ischemia (BCDA-02). Our allogeneic mesenchymal stem cell therapy platform, derived from donor cells and intended to be provided “off the shelf,” is also being advanced for two indications, heart failure (BCDA-03) and for the pulmonary indication of acute respiratory distress that has developed from COVID-19 (BCDA-04).

Our Helix™ Biotherapeutic Delivery System platform, or Helix, delivers therapeutics into the heart muscle with a helical needle from within the heart. It enables local delivery of cell, gene and protein-based therapies, including our own cell therapies to treat cardiac indications. The Helix system is CE marked in Europe and under investigational use in the United States. We selectively partner with firms developing other cell, gene and protein therapies utilizing the Helix and other biotherapeutic delivery systems that we have developed.  

CardiAMP Cell Therapy for Heart Failure and Chronic Myocardial Ischemia

The Company’s lead platform, CardiAMP cell therapy, is an autologous cell therapy being advanced for two indications in pivotal clinical trials: heart failure and chronic myocardial ischemia.

BCDA-01 CardiAMP Autologous Cell Therapy for Ischemic Heart Failure

The CardiAMP Heart Failure Trial is a Phase III, multi-center, randomized, double-blinded, sham-controlled study of up to 260 patients at 40 centers nationwide, which includes a 10-patient roll-in cohort. The Phase III pivotal trial is designed to provide the primary support for the safety and efficacy of the CardiAMP Cell Therapy System for heart failure which develops after a patient has a heart attack (BCDA-01). The trial is active at 20 clinical sites and 115 patients have been enrolled.  

In January 2022, the U.S. Food and Drug Administration (FDA) granted Breakthrough Device Designation for the CardiAMP Cell Therapy System for the treatment of heart failure. This Breakthrough Device Program is designed to expedite FDA approval of certain novel devices or device-led combination products (i.e., products that combine drugs, devices or biological products) that have the potential to provide more effective treatment or diagnosis of life-threatening or irreversibly debilitating diseases or conditions. It is believed that the CardiAMP Cell Therapy System is the first cardiac cell therapy to receive an FDA Breakthrough designation.   

In February 2022, Health Canada, the country’s health services agency, sent BioCardia a No Objection Letter, allowing the CardiAMP Heart Failure Trial to expand into Canada. Four world-class Canadian clinical sites are currently working through the activation process to begin enrolling patients in the near future. The first of these four new Canadian sites, the Ottawa Heart Institute is now actively enrolling in the trial. Three additional Canadian centers are expected to be activated in the coming months.

In May 2022, the Center for Medicare and Medicaid Services issued code C9782 for: “Blinded procedure for New York Heart Association (NYHA) Class II or III heart failure, or Canadian Cardiovascular Society (CCS) Class III or IV chronic refractory angina; transcatheter intramyocardial transplantation of autologous bone marrow cells (e.g., mononuclear) or placebo control, autologous bone marrow harvesting and preparation for transplantation, left heart catheterization including ventriculography, all laboratory services, and all imaging with or without guidance (e.g., transthoracic echocardiography, ultrasound, fluoroscopy), all device(s), performed in an approved Investigational Device Exemption (IDE) study.” This reimbursement is for up to $20,000 effective from April 1, 2022 and is applicable to both the CardiAMP autologous cell therapy program in ischemic heart failure and the trial in chronic myocardial ischemia.

In July 2022, the Company had its second consultation with Japan’s Pharmaceutical and Medical Device Agency regarding potential approval of the CardiAMP Cell Therapy System for the treatment of ischemic heart failure based on existing data. Throughout the third quarter, efforts developing the submission to PMDA for a third formal consultation continued and are substantially complete. BioCardia is requesting a Japanese cardiovascular society petition the Ministry of Health Labor and Welfare that this device is a much needed medical device, which may convey certain benefits to the approval and reimbursement of the CardiAMP System in Japan. This petition must be done in advance of BioCardia’s submission for approval.

On August 30, 2022, the independent Data Safety Monitoring Board (DSMB) completed a prespecified data review, including a risk-benefit assessment. Following the review, the DSMB indicated that it had no significant safety concerns and recommended that the study continue as designed. The DSMB also recommended that the Company consider implementing an adaptive statistical analysis plan, which could enable an early readout for study treatment efficacy.

An adaptive statistical analysis plan is one which attempts to determine the appropriate number of patients needed in a clinical study based on the data within the trial itself as opposed to data from a previous trial. This has the significant advantage of de-risking the trial from changes that have occurred in the current trial relative to previous trials. Subsequent trials have potential to have better results as they are informed by previous trials, but there may also be more variation in the data as trials are expanded to many clinical centers. Both of these can impact the success of a clinical trial in meeting its primary endpoint. In reviewing the data during a DSMB meeting under an adaptive statistical analysis plan, the DSMB may be able to assess at certain points in the clinical trial how many patients should be enrolled in the trial to meet the primary endpoint in the trial. If a trial has already enrolled the number of patients expected to be required to show efficacy, then there is potential that the DSMB informs the sponsor that the trial enrollment might be stopped for expected success.

Efforts are underway to complete an adaptive statistical analysis plan for the CardiAMP Heart Failure Trial Executive Steering Committee and the FDA to review and comment on. In parallel, our clinical operations team is working to ensure that clinical data that the DSMB would use in such an adaptive review of the study statistics is correct through extensive monitoring of the clinical data in collaboration with our clinical partners. This is often referred to as cleaning the data and is a significant effort. The next prespecified formal DSMB review is anticipated in March 2023 and based on conversations the Company has had with the intended developers of the adaptive Statistical Analysis Plan and its respected regulatory consultants, and our own efforts cleaning the data, the Company believes it is likely to be able to have the adaptive statistical analysis plan in place for the next DSMB meeting. The specific details of any potential adaptive statistical analysis plan in combination with any modifications to the DSMB Charter will dictate what happens at this next and subsequent DSMB reviews.

As the CardiAMP Cell Therapy Trial in Heart Failure was over 90% powered for success based on the Phase II data, there is potential that the trial could meet its primary efficacy endpoint on the patients that have been enrolled to date. However, when the DSMB next meets, they may also share that the trial continue per plan, be stopped for safety, or be stopped for futility if the data does not support that achieving the primary endpoint is possible.

In October 2022, at the Heart Failure Society of America annual meeting, two-year data on the ten patient roll-in cohort was presented. In this clinical trial cohort, patient demographics at study start demonstrated characteristics typical of the target population of NYHA class II and III ischemic heart failure patients with reduced ejection fraction. No serious adverse events were observed related to any of the procedures performed. Two-year survival was 100%, and all patients completed 24 months of follow-up. The changes in guideline-directed medical therapy experienced by these patients were presented as minimal during the two-year study period. Improvement in median functional capacity as measured by six-minute walk distance was observed by six months (28.5 m, P=0.01); with six-minute walk distance maintained through 24 months (31.0 m, p >0.05). In the study, 70% of patients reported improved or stable quality of life over 24 months in the standardized self- assessment questionnaire used. At 24 months, 50% of patients were improved by at least one NYHA class (n=4 at class I), 20% had unchanged NYHA class, and 30% deteriorated by one class, from class II to III. Median left ventricular ejection fraction (LVEF) as measured by the echocardiography core laboratory at Yale School of Medicine was improved at month 24 over baseline, six months, and over 12-month follow-up. Echocardiography evaluated by the core lab also showed recruitment of previously akinetic (reduced movement) left ventricular wall segments at month 24 compared to baseline, consistent with the improvements in six-minute walk distance, quality of life, and LVEF through two years follow-up. These outcomes support the potential efficacy of this autologous cell therapy currently under investigation in an ongoing multicenter controlled trial.

16

In October 2022, an update to www.CardiAMP.com, a website to educate patients and physicians about the clinical trial went live and was approved by a central independent Institutional Review Board. For the first time, the Company has patients who can share their experiences with other patients, which we feel has promise to enhance enrollment and awareness in the CardiAMP Heart Failure trial.

In October 2022, we also held a national clinical study site coordinators meeting to work through enrollment and clinical issues and build a best practices approach to efficient performance of the clinical trial which is ongoing.

BCDA-02 CardiAMP Autologous Cell Therapy for Chronic Myocardial Ischemia

The CardiAMP Chronic Myocardial Ischemia Trial is a Phase III, multi-center, randomized, double-blinded, controlled study of up to 343 patients at up to 40 clinical sites. The Phase III pivotal trial is designed to provide the primary support for the safety and efficacy of the CardiAMP Cell Therapy System for the indication of chronic myocardial ischemia (BCDA-02). This therapeutic approach uses many of the same novel aspects as the CardiAMP Heart Failure Trial and is expected to leverage our experience and investment in the heart failure trial. This program benefits from the 2022 CMS reimbursement at up to $20,000. The trial has been activated at two centers and the Company is working to activate additional centers and deliver safety results from the roll-in cohort.

Allogeneic Cell Therapy for Cardiac and Pulmonary Disease (BCDA-03 and BCDA-04)

Our second therapeutic platform is our investigational culture expanded bone marrow derived allogeneic, Neurokinin-1 Receptor Positive mesenchymal stem cells (NK1R+ MSC). This “off the shelf” mesenchymal cell therapy is being advanced for cardiac and pulmonary disease. BioCardia’s established and certified ISO 7 cleanroom has been developed to manufacture its allogeneic NK1R+MSC investigational cell therapy products.

BCDA-03

We are working to secure FDA acceptance of an IND application for a Phase I/II trial to deliver these allogeneic cells for the treatment of ischemic systolic heart failure. We have completed the manufacturing validation runs and stability testing for the Chemistry Manufacturing and Controls section of the IND. We have completed the  preclinical pharmacology toxicology animal testing with no safety issues and with trends towards therapeutic benefit. The IND application for this program was filed with FDA CBER in early November 2022.  The Company anticipates FDA approval of the IND in early December.

BCDA-04

In April 2022, the FDA approved the Company’s Investigational New Drug (IND) for a Phase I/II trial for the use of this allogeneic cell therapy for Acute Respiratory Distress Syndrome (ARDS) caused by COVID-19 (BCDA-04). This allows the Company to initiate its First-in-Human Phase I/II trial in adult patients recovering from ARDS due to COVID-19, with trial initiation expected in 2022. The first part of the clinical trial will evaluate increasing dosages of the NK1R+ MSCs and the optimal dose will be taken to Phase II in a randomized study in adult patients recovering from ARDS due to COVID-19. This therapy is intended to address the enormous unmet need of sustained local and systemic inflammation after a patient is taken off respirator support with goals of accelerating recovery, enhancing survival and reducing both relapse and rehospitalization. A first clinical study manufacturing run from our Sunnyvale facility has been completed with cells cryopreserved, awaiting final longer lead time test data for lot release before they are able to be shipped to centers for patients in the clinical study. This manufacturing run has potential to have sufficient cells to complete the entire Phase I portion of the Phase I/II trial as we achieve many doses with each batch. We are also in late-stage contracting, budgeting and institutional review board discussions with world class clinical centers to perform the clinical trial.

Recent Developments

COVID-19 Considerations

As a result of the COVID-19 pandemic, we have experienced significant disruption to the Company’s business and delays in the Company’s development programs and regulatory and commercialization timelines, including adverse impact to our operations at certain clinical sites involved in our ongoing clinical studies. The COVID-19 pandemic could continue to adversely affect our business, results of operations, financial condition and/or liquidity in the future. These adverse impacts could include delayed or slowed enrollment of our, or our collaborators’, planned or ongoing clinical trials, delayed or cancelled clinical site initiations, delayed regulatory review for regulatory approvals, delayed commercialization of one or more of our product candidates, if approved, and workforce shortages. Our production capabilities, or those of our partners or suppliers, and our supply chains could also be adversely impacted.

17

Additionally, while the potential continuing economic impact brought by, and the duration of, the COVID-19 pandemic is difficult to assess or predict, the impact of COVID-19 on the global financial markets may reduce the Company’s ability to access capital, which could negatively impact the Company’s liquidity and ability to raise the capital to complete its preclinical and clinical studies on a timely basis, or at all. In addition, a recession, market correction or depression resulting from the COVID-19 pandemic or the response to it, could materially affect our business and the value of our common stock.

Financial Overview

Revenue

We currently have a portfolio of enabling and delivery products, from which we have generated modest revenue. Net product revenues include commercial sales of our Morph vascular access system in the US and EU and collaboration agreement revenues include revenue from partnering agreements with corporate and academic institutions. Under these partnering agreements, we provide our Helix biotherapeutic delivery system and customer training and support for use in preclinical and clinical studies.

Research and Development Expenses

Our research and development expenses consist primarily of:

• salaries and related overhead expenses, which include share-based compensation and benefits for personnel in research and development functions;

• fees paid to consultants and contract research organizations, or CROs, including in connection with our preclinical studies and clinical trials and other related clinical trial fees, such as for investigator grants, patient screening, laboratory work, clinical trial management and statistical compilation and analysis;

• costs related to acquiring and manufacturing clinical trial materials;

• costs related to compliance with regulatory requirements; and

• payments related to licensed products and technologies.

We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized based on an evaluation of the progress of completion of specific tasks using information and data provided to us by our vendors and clinical sites. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development activities are deferred and capitalized. The capitalized amounts are then expensed as the related goods are delivered and the services are received. 

We plan to increase our research and development expenses for the foreseeable future as we continue the pivotal CardiAMP autologous cell therapy trials in heart failure and chronic myocardial ischemia, and begin our allogeneic cell therapy trials in heart failure and acute respiratory distress syndrome. We typically use our employee and infrastructure resources across multiple research and development programs, and accordingly, we have not historically allocated resources specifically to our individual programs. There are also significant synergies between these programs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of salaries and related costs for employees in executive, finance and administration, sales, corporate development and administrative support functions, including share-based compensation expenses and benefits. Other selling, general and administrative expenses include sales commissions, rent, accounting and legal services, obtaining and maintaining patents, the cost of consultants, occupancy costs, insurance premiums and information systems costs.

Other Income (Expense)

Other income and expense consist primarily of interest income we earn on our cash and cash equivalents.

Critical Accounting Policies and Estimates

Our 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 U.S. GAAP. The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities. We evaluate these estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various judgements 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 clear from other sources. Actual results may differ from these estimates under different assumptions or conditions. 

The full extent to which the ongoing COVID-19 pandemic will directly or indirectly impact our business, results of operations and financial condition, including revenues, expenses, reserves and allowances, manufacturing, clinical trials and research and development will depend on future developments that continue to remain highly uncertain at this time. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods.

We define our critical accounting policies as those that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations as well as the specific manner in which we apply those principles. Our critical accounting policies are described in Item 7 in our Annual Report on Form 10-K for the year ended December 31, 2021. 

Results of Operations

Comparison of Three and Nine Months Ended September 30, 2022 and 2021

The following table summarizes our results of operations for the three and nine months ended September 30, 2022 and 2021 (in thousands):

Net loss	$	(3,057	)	$	(2,706	)	$	(8,879	)	$	(9,162	)

Revenue. Revenue decreased to $212,000 in the third quarter of 2022 as compared to $821,000 in the third quarter of 2021, and increased to $1,246,000 in the nine months ended September 30, 2022 as compared to $936,000 in the nine months ended September 30, 2021, primarily due to the timing of fulfilment of deliverables and completion of collaborative agreements. The amount and timing of collaboration revenues is largely dependent on our partners’ development activities and may be inconsistent and create significant quarter-to-quarter variation in our revenues.

Research and Development Expenses. Research and development expenses decreased to $2,144,000 in the third quarter of 2022 as compared to $2,240,000 in the third quarter of 2021, primarily due to lower stock-based compensation and expenses incurred in the execution of the pivotal CardiAMP Heart Failure trial. Research and development expenses increased to $6,634,000 in the nine months ended September 30, 2022 as compared to $6,443,000 in the nine months ended September 30, 2021 primarily due to increasing expenses in support of the CardiAMP Heart Failure Trial.

Selling, General and Administrative Expenses.  Selling, general and administrative expenses decreased to $1,128,000 in the third quarter of 2022 as compared to $1,289,000 in the third quarter of 2021, primarily due to lower stock-based compensation and lower service provider expenses. Selling, general and administrative expenses decreased to $3,495,000 in the nine months ended September 30, 2022 as compared to $3,662,000 in the nine months ended September 30, 2021, primarily due to lower stock-based compensation.

19

Liquidity and Capital Resources

We have incurred net losses each year since our inception and as of September 30, 2022, we had an accumulated deficit of approximately $137.6 million. We anticipate that we will continue to incur net losses for the next several years.

We have funded our operations principally through the sales of equity and convertible debt securities. As of September 30, 2022, we had cash and cash equivalents of approximately $6.7 million. 

The following table shows a summary of our cash flows for the periods indicated (in thousands): 

	Nine months ended September 30,
	2022			2021
Net cash provided by (used in):
Operating activities	$	(7,564	)	$	(7,391	)
Investing activities		(68	)		(75	)
Financing activities		1,427			1,947
Net decrease in cash and cash equivalents	$	(6,205	)	$	(5,519	)

Cash Flows from Operating Activities. The increase in overall spending for operating activities of approximately $173,000 in the nine months ended September 30, 2022 compared to the nine months ended September 30, 2021 related primarily to the timing of payments from collaboration partners.

Cash Flows from Investing Activities. Net cash used in investing activities of $68,000 and $75,000 during the nine months ended September 30, 2022 and 2021, respectively, consisted of purchases of property and equipment, primarily lab and office equipment.

Cash Flows from Financing Activities. Net cash provided by financing activities of $1,427,000 during the nine months ended September 30, 2022 related primarily to net proceeds from the sale of common stock. Net cash provided by financing activities of $1,947,000 during the nine months ended September 30, 2021 related primarily to net proceeds from the sale of common stock in March 2021. 

Lincoln Park Capital Stock Purchase Agreement

In March 2021, we and Lincoln Park Capital Fund, LLC (Lincoln Park) entered into a purchase agreement (the Purchase Agreement) and a registration rights agreement (the Registration Rights Agreement), pursuant to which we have the right to sell to Lincoln Park shares of our common stock having an aggregate value of up to $20 million, subject to certain limitations and conditions set forth in the Purchase Agreement. Pursuant to the terms of the Purchase Agreement, at the time we signed the Purchase Agreement, we sold 373,832 shares of our common stock at a price of $5.35 per share pursuant to the Purchase Agreement for gross proceeds of $2 million (and issued 80,000 shares of common stock to Lincoln Park as consideration for its commitment to purchase shares of our common stock, which consisted of 75,000 shares for Lincoln Park’s initial commitment and 5,000 shares issued on a pro rata basis in respect of Lincoln Park’s initial purchase of 373,832 shares). Thereafter, as often as every business day from and after one business day following the date of the Initial Purchase and over the 36-month term of the Purchase Agreement, we have the right, from time to time, at our sole discretion and subject to certain conditions, to direct Lincoln Park to purchase up to 100,000 shares of common stock, with such amount increasing as the closing sale price of the common stock increases; provided Lincoln Park’s obligation under any single such purchase will not exceed $2 million, unless we and Lincoln Park mutually agree to increase the maximum amount of such single purchase (each, a Regular Purchase). If we direct Lincoln Park to purchase the maximum number of shares of common stock it then may sell in a Regular Purchase, then in addition to such Regular Purchase, and subject to certain conditions and limitations in the Purchase Agreement, we may direct Lincoln Park in an Accelerated Purchase to purchase an additional amount of common stock that may not exceed the lesser of (i) 300% of the number of shares purchased pursuant to the corresponding Regular Purchase or (ii) 30% of the total number of shares of our common stock traded during a specified period on the applicable purchase date as set forth in the Purchase Agreement. Under certain circumstances and in accordance with the Purchase Agreement, we may direct Lincoln Park to purchase shares in multiple Accelerated Purchases on the same trading day. We expect to use the proceeds from this agreement for general corporate purposes and working capital. As of September 30, 2022, the Company had not made any sales of common stock to Lincoln Park under the Purchase Agreement other than the Initial Purchase.

Cantor Fitzgerald ATM Offering

On April 12, 2022, we entered into a sales agreement (the Sales Agreement) with Cantor Fitzgerald & Co. (Cantor) as the sales agent, pursuant to which we may offer and sell, from time to time, through Cantor, shares of our common stock having an aggregate offering price of up to $10.5 million (the ATM Offering). We are not obligated to sell any common stock shares pursuant to the Sales Agreement. Under the terms of the Sales Agreement, we will pay Cantor a commission of 3% of the aggregate proceeds from the sale of shares and reimburse certain legal fees.

During the three months ended September 30, 2022, we sold 66,704 shares of common stock under the ATM Offering at then-market prices for total gross proceeds of $139,000, with a net refund of issuance costs of $1,000. During the nine months ended September 30, 2022, we sold 641,704 shares of common stock under the ATM Offering at then-market prices for total gross proceeds of approximately $1.7 million, with associated issuance costs of $231,000.

Future Funding Requirements

To date, we have generated modest revenues. We do not know when, or if, we will generate any revenue from our development stage biotherapeutic programs. We do not expect to generate any revenue from sales of our autologous and allogeneic cell therapy candidates unless and until we obtain regulatory approval. At the same time, we expect our expenses to increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our therapeutic candidates. In addition, subject to obtaining regulatory approval for any of our therapeutic candidates and companion diagnostic, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need additional funding in connection with our continuing operations.     

Based upon our current operating plan, we believe that the cash and cash equivalents of approximately $6.7 million as of September 30, 2022 are not sufficient to fund our planned expenditures and meet our obligations beyond April 2023. In order to continue development of our therapeutic candidates beyond April 2023, we plan to raise additional capital, potentially including non-dilutive collaboration and licensing arrangements, debt or equity financing, or a combination from these sources. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of our therapeutic candidates, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the development of our therapeutic candidates.

Our future capital requirements will depend on many factors, including:

• the progress, costs, results and timing of our autologous CardiAMP Cell Therapy System and allogeneic Neurokinin-1 Receptor Positive clinical trials and related development programs;

• FDA acceptance of our autologous CardiAMP Cell Therapy System and allogeneic Neurokinin-1 Receptor Positive therapies for heart failure and for other potential indications;

• the outcome, costs and timing of seeking and obtaining FDA and any other regulatory approvals;

• the costs associated with securing, establishing and maintaining commercialization and manufacturing capabilities;

• the number and characteristics of product candidates that we pursue, including our product candidates in preclinical development;

• the ability of our product candidates to progress through clinical development successfully;

• our need to expand our research and development activities;

• the costs of acquiring, licensing, or investing in businesses, products, product candidates and technologies;

• our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;

• the general and administrative expenses related to being a public company;

• our need and ability to hire additional management and scientific, medical and sales personnel;

• the effect of competing technological and market developments;

• our need to implement additional internal systems and infrastructure, including financial and reporting systems; and

• the cost of the impact from the COVID-19 pandemic.

21

Until such time that we can generate meaningful revenue from the sales of approved therapies and products, if ever, we expect to finance our operating activities through public or private equity or debt financings, government or other third-party funding, marketing and distribution arrangements, and other collaborations, strategic alliances and licensing arrangements or a combination of these approaches. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our common stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing, if available, may involve agreements that include conversion discounts or covenants limiting or restricting our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends. If we raise additional funds through government or other third-party funding, marketing and distribution arrangements or other collaborations, or strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, products, or therapeutic candidates or to grant licenses on terms that may not be favorable to us.

Our condensed consolidated financial statements as of September 30, 2022 have been prepared on the basis that the Company will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. Due to the factors described above, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date these financial statements are issued. Our ability to continue as a going concern will depend in a large part, on our ability to raise additional capital. If adequate funds are not available, we may be required to reduce operating expenses, delay or reduce the scope of our product development programs, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize ourselves, or cease operations. While we believe in the viability of our strategy to raise additional funds, there can be no assurances that we will be able to obtain additional capital on acceptable terms and in the amounts necessary to fully fund our operating needs.

The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. If we are unable to continue as a going concern, we may be forced to liquidate assets. In such a scenario, the values received for assets in liquidation or dissolution could be significantly lower than the values reflected in our condensed consolidated financial statements. 

Off-Balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, any off-balance sheet arrangements as defined under the rules of the Securities and Exchange Commission.

Recent Accounting Pronouncements

See Note 2 of our notes to condensed consolidated financial statements for information regarding recent accounting pronouncements that are of significance or potential significance to us.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in our market risks during the three months ended September 30, 2022.

Our exposure to market risk is currently limited to our cash and cash equivalents, all of which have maturities of less than three months. The goals of our investment policy are preservation of capital, maintenance of liquidity needs, and fiduciary control of cash and investments. We also seek to maximize income from our investments without assuming significant risk or departing from our investment policy. We currently do not hedge interest rate exposure. Because of the short-term nature of our cash equivalents, we do not believe that an increase in market rates would have a material negative impact on the value of our portfolio.

Interest Rate Risk

As of September 30, 2022, based on current interest rates and total borrowings outstanding, a hypothetical 100 basis point increase or decrease in interest rates would have an immaterial pre-tax impact on our results of operations.

Foreign Currency Exchange Risks

We are a U.S. entity and our functional currency is the U.S. dollar. The vast majority of our revenues were derived from sales in the United States. We have business transactions in foreign currencies; however, we believe we do not have significant exposure to risk from changes in foreign currency exchange rates at this time. We do not currently engage in hedging or similar transactions to reduce our foreign currency risks. We will continue to monitor and evaluate our internal processes relating to foreign currency exchange, including the potential use of hedging strategies.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In connection with the preparation of this Quarterly Report on Form 10-Q, as of September 30, 2022, an evaluation was performed under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of September 30, 2022, our disclosure controls and procedures were, in design and operation, effective at a reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes to our internal control over financial reporting identified in connection with the evaluation required by rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the three months ended September 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

23

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company may be subject to various claims, complaints, and legal actions that arise from time to time in the normal course of business. Management does not believe that the Company is party to any current pending legal proceedings. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not have a material adverse effect on the Company’s business, financial position, results of operations, or cash flows.  

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2021, which could materially affect our business, financial condition, or future results. The risks described in this report, our Annual Report on Form 10-K for the year ended December 31, 2021, and our Quarterly Reports on Form 10-Q filed periodically with the SEC are not the only risks facing our Company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Business Description and Basis of Presentation [Text Block]

(1) Summary of Business and Basis of Presentation

(a)	Description of Business
	BioCardia, Inc. (we, us, our, BioCardia or the Company), is a clinical-stage company focused on developing cellular and cell-derived therapeutics for the treatment of cardiovascular and pulmonary diseases with significant unmet medical needs. The Company’s lead therapeutic candidates are based on the CardiAMP Cell Therapy System, a platform which provides an autologous bone marrow derived cell therapy for treatment in two clinical indications: ischemic heart failure and refractory angina resulting from chronic myocardial ischemia. The Company’s second therapeutic platform is an investigational bone marrow derived allogeneic “off the shelf” Neurokinin-1 Receptor Positive mesenchymal stem cell therapy for the treatment of cardiac and pulmonary disease. To date, we have devoted substantially all our resources to research and development efforts relating to our therapeutic candidates and biotherapeutic delivery systems including conducting clinical trials, developing manufacturing and sales capabilities, in-licensing related intellectual property, providing general and administrative support for these operations and protecting our intellectual property.
	BioCardia also has three enabling device product lines: (1) the CardiAMP cell processing system; (2) the Helix biotherapeutic delivery system, or Helix; and (3) the Morph vascular access product line, or Morph. We manage our operations as a single segment for the purposes of assessing performance and making operating decisions.

(2) Significant Accounting Policies

(a)

Basis of Preparation

The accompanying condensed consolidated balance sheets, statements of operations, stockholders’ equity, and cash flows as of September 30, 2022, and for the three and nine months ended September 30, 2022 and 2021 are unaudited. The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information and on a basis consistent with the annual financial statements and, in the opinion of management, reflect all adjustments which include only normal recurring adjustments, necessary to present fairly its financial position as of September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, and cash flows for the nine months ended September 30, 2022 and 2021. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or for any other future year. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 29, 2022.

(b)	Liquidity – Going Concern
	We have incurred net losses and negative cash flows from operations since our inception and had an accumulated deficit of approximately $137.6 million as of September 30, 2022. Management expects operating losses and negative cash flows to continue through at least the next several years. We expect to incur increasing costs as we advance our trials and development activities. Therefore, absent additional funding, management believes cash and cash equivalents of approximately $6.7 million as of September 30, 2022 are not sufficient to fund the Company’s planned expenditures and meet its obligations beyond April 2023. These factors raise substantial doubt about the Company’s ability to continue as a going concern beyond one year from the date these financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
	The Company’s ability to continue as a going concern and to continue further development of its therapeutic candidates beyond April 2023, will require the Company to raise additional capital. The Company plans to raise additional capital, potentially including debt and equity arrangements, to finance its future operations. While management believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt, these plans are not entirely within its control and cannot be assessed as being probable of occurring. If adequate funds are not available, we may be required to reduce operating expenses, delay or reduce the scope of our product development programs, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize, or cease operations.

(c)

Use of Estimates

The preparation of the financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Significant items subject to such estimates and assumptions include share-based compensation, the useful lives of property and equipment, right-of-use assets and related liabilities, incremental borrowing rate, allowances for doubtful accounts and sales returns, clinical accruals and assumptions used for revenue recognition.

(d)	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, BioCardia Lifesciences, Inc. All intercompany accounts and transactions have been eliminated during the consolidation process.

(e)	Changes to Significant Accounting Policies
	The Company’s significant accounting policies are described in Note 2 of the notes to the consolidated financial statements included in its Annual Report on Form 10-K filed March 29, 2022 for the year ended December 31, 2021. There have been no changes to those policies.

(f)	Recent Accounting Pronouncements
	Recent accounting pronouncements issued by the Financial Accounting Standards Board (FASB), including its Emerging Issues Task Force did not or are not believed by management to have a material impact on our financial statement presentation or disclosures.

Fair Value Disclosures [Text Block]

(3) Fair Value Measurement

The fair value of financial instruments reflects the amounts that we estimate to receive in connection with the sale of an asset or paid in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). We follow a fair value hierarchy that prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1 – quoted prices in active markets for identical assets and liabilities.

Level 2 – observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following table sets forth the fair value of its financial assets measured on a recurring basis as of September 30, 2022 and December 31, 2021 and indicates the fair value hierarchy utilized to determine such fair value (in thousands):

Lessee, Operating Leases [Text Block]

(5) Operating Lease Right-of-Use Asset, Net

Our operating lease related to a property lease for our laboratory and corporate offices expired in December 2021, and we entered into a new lease which expires in January 2027, with an option for us to extend a further 36 months after expiration. Our lease agreements do not contain any material residual guarantees or material restrictive covenants. We determine if an arrangement is a lease at inception by assessing whether it conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Right-of-use (ROU) assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The Company’s lease does not provide an implicit rate. We used an adjusted historical incremental borrowing rate, based on the information available at the approximate lease commencement date, to determine the present value of lease payments. Variable rent expense is made up of expenses for common area maintenance and shared utilities and were not included in the determination of the present value of lease payments. We have no finance leases.

Our lease expense for the three and nine months ended September 30, 2022 was $121,000 and $362,000, respectively. Our lease expense for the three and nine months ended September 30, 2021 was $150,000 and $451,000, respectively. The cash paid under the operating lease for base rent for the three and nine months ended September 30, 2022 was $114,000 and $287,000, respectively. The cash paid under the operating lease during the three and nine months ended September 30, 2021 was $162,000 and $486,000, respectively. On September 30, 2022, the weighted average remaining lease term was 4.34 years, and the weighted average discount rate was 10.74%.

Future minimum lease payments under the operating lease as of September 30, 2022 were as follows (in thousands):

RSUs vested and settled are converted into the Company’s common stock on a one-for-one basis. RSUs are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. Of the 52,799 RSUs outstanding on September 30, 2022, 50,065 RSUs are vested and have not been settled and 2,734 have not yet vested. The related compensation expense, which is based on the grant date fair value of the Company’s common stock multiplied by the number of units granted, is recognized ratably over the period during which the vesting restrictions lapse. Unrecognized share-based compensation for employee and nonemployee RSUs granted through September 30, 2022 is approximately $7,000 to be recognized over a remaining weighted average service period of 0.6 years.

Basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding and fully vested restricted stock units. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. Common stock equivalents are comprised of unvested restricted stock units, warrants to purchase common stock and options outstanding under the stock option plans. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding since the effects of potentially dilutive securities are antidilutive due to the net loss position.

The following outstanding common stock equivalents were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive: 

	September 30,
	2022		2021
Stock options to purchase common stock		2,148,732		1,684,066
Unvested restricted stock units		2,734		5,468
Common stock warrants		2,424,724		2,424,724

Income Tax Disclosure [Text Block]

(10) Income Taxes

During the three and nine months ended September 30, 2022 and 2021, there was no income tax expense or benefit for federal or state income taxes in the accompanying condensed consolidated statements of operations due to the Company’s net loss and a full valuation allowance on the resulting deferred tax assets.

As of September 30, 2022, the Company retains a full valuation allowance on its deferred tax assets in all jurisdictions. The realization of its deferred tax assets depends primarily on its ability to generate future taxable income which is uncertain. The Company does not believe that its deferred tax assets are realizable on a more-likely-than-not basis; therefore, the net deferred tax assets have been fully offset by a valuation allowance.

(11) Related Party Transactions

On April 9, 2020, the Company entered into a Litigation Funding Agreement (the Funding Agreement) with BSLF, L.L.C. (the Funder), an entity owned and controlled by Andrew Blank, Chair of BioCardia’s board of directors, for the purpose of funding the Company’s legal proceedings and any and all claims, actions and/or proceedings relating to or arising from the case captioned Boston Scientific Corp., et al., v. BioCardia Inc., Case No. 3:19-05645-VC, U.S.D.C., N. D. Cal (the Litigation). On April 12, 2021, all parties to the Litigation entered into a confidential settlement agreement and all claims were dismissed.

In March 2022, the Company entered into settlement agreements with its litigation service providers and the Funder to terminate the Funding Agreement and conclude on all remaining matters thereunder (the Litigation Funding Settlement). Under the terms of the confidential agreements, litigation and corporate counsel provided credits and refunds of legal fees totaling $688,000, which offset the amounts owed to the Company by the Funder under the Funding Agreement, and provided up to $300,000 in future discounts on legal services. As a result of the Litigation Funding Settlement, the Company will remit the discounts, as received, to the Funder on a quarterly basis. As a result of the settlement, accounts payable was reduced by $523,000, the $562,000 other receivable due from the related party was eliminated, and a $156,000 related party payable was included in accrued expenses and other current liabilities as of December 31, 2021. The Company remitted the $156,000 related party payable to the Funder on March 17, 2022. During the three and nine months ended September 30, 2022, the Company received discounts totaling $14,000 and $61,000, respectively, with $14,000 recorded as a related party payable in accrued expenses and other current liabilities as of September 30, 2022.

(12) Contingencies and Uncertainties

Contingencies - The Company may be subject to various claims, complaints, and legal actions that arise from time to time in the normal course of business. Management is not aware of any current legal or administrative proceedings that are likely to have an adverse effect on the Company’s business, financial position, results of operations, or cash flows.

Uncertainties - The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ending December 31, 2022 or for any other interim period or for any other future year, particularly in light of COVID-19 and its impact on domestic and global economies. Governmental and business reactions to the pandemic, and resulting economic disruptions, have the potential to materially impact our business and influence our business decisions. While the impact of COVID-19 did not have a material adverse effect on our financial position or results of operations for the periods presented, the Company’s future assessment of the magnitude and duration of COVID-19 and related factors, could result in material impacts to the Company’s financial statements in future reporting periods.

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

(a)

Basis of Preparation

The accompanying condensed consolidated balance sheets, statements of operations, stockholders’ equity, and cash flows as of September 30, 2022, and for the three and nine months ended September 30, 2022 and 2021 are unaudited. The condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (U.S. GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) for interim financial information and on a basis consistent with the annual financial statements and, in the opinion of management, reflect all adjustments which include only normal recurring adjustments, necessary to present fairly its financial position as of September 30, 2022, results of operations for the three and nine months ended September 30, 2022 and 2021, and cash flows for the nine months ended September 30, 2022 and 2021. The results for the three and nine months ended September 30, 2022 are not necessarily indicative of the results to be expected for the year ended December 31, 2022 or for any other interim period or for any other future year. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 29, 2022.

Going Concern and Liquidity [Policy Text Block]

(b)	Liquidity – Going Concern
	We have incurred net losses and negative cash flows from operations since our inception and had an accumulated deficit of approximately $137.6 million as of September 30, 2022. Management expects operating losses and negative cash flows to continue through at least the next several years. We expect to incur increasing costs as we advance our trials and development activities. Therefore, absent additional funding, management believes cash and cash equivalents of approximately $6.7 million as of September 30, 2022 are not sufficient to fund the Company’s planned expenditures and meet its obligations beyond April 2023. These factors raise substantial doubt about the Company’s ability to continue as a going concern beyond one year from the date these financial statements are issued. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
	The Company’s ability to continue as a going concern and to continue further development of its therapeutic candidates beyond April 2023, will require the Company to raise additional capital. The Company plans to raise additional capital, potentially including debt and equity arrangements, to finance its future operations. While management believes this plan to raise additional funds will alleviate the conditions that raise substantial doubt, these plans are not entirely within its control and cannot be assessed as being probable of occurring. If adequate funds are not available, we may be required to reduce operating expenses, delay or reduce the scope of our product development programs, obtain funds through arrangements with others that may require us to relinquish rights to certain of our technologies or products that we would otherwise seek to develop or commercialize, or cease operations.

Use of Estimates, Policy [Policy Text Block]

(c)

Use of Estimates

The preparation of the financial statements in accordance with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Significant items subject to such estimates and assumptions include share-based compensation, the useful lives of property and equipment, right-of-use assets and related liabilities, incremental borrowing rate, allowances for doubtful accounts and sales returns, clinical accruals and assumptions used for revenue recognition.

Consolidation, Policy [Policy Text Block]

(d)	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, BioCardia Lifesciences, Inc. All intercompany accounts and transactions have been eliminated during the consolidation process.

Change to Significant Accounting Policies [Policy Text Block]

(e)	Changes to Significant Accounting Policies
	The Company’s significant accounting policies are described in Note 2 of the notes to the consolidated financial statements included in its Annual Report on Form 10-K filed March 29, 2022 for the year ended December 31, 2021. There have been no changes to those policies.

New Accounting Pronouncements, Policy [Policy Text Block]

(f)	Recent Accounting Pronouncements
	Recent accounting pronouncements issued by the Financial Accounting Standards Board (FASB), including its Emerging Issues Task Force did not or are not believed by management to have a material impact on our financial statement presentation or disclosures.
