(1) Summary of Business and Basis of Presentation

(a)	Description of Business
	BioCardia, Inc., (BioCardia or the Company), is a clinical-stage regenerative medicine company developing novel therapeutics for cardiovascular diseases with significant unmet medical needs. The Company’s lead therapeutic candidate is the CardiAMP® cell therapy system and its second therapeutic candidate is the CardiALLO™ cell therapy system. To date, the Company has devoted substantially all its resources to research and development efforts relating to its 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 its 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. The Company manages its 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, shareholders’ equity, and cash flows as of June 30, 2020 and for the three and six months ended June 30, 2020 and 2019 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 June 30, 2020, results of operations for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ended December 31, 2020 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, 2019, filed with the SEC on April 9, 2020.  The results for the three months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or for any other interim period or for any other future year, particularly in light of the novel coronavirus pandemic, or COVID-19, and its impact on domestic and global economies. To limit the spread of COVID-19, governments have taken various actions including the issuance of stay-at-home orders and social distancing guidelines, causing some businesses to suspend operations and/or experience a reduction in demand for many products from direct or ultimate customers. Accordingly, businesses have adjusted, reduced or suspended operating activities and are continuing to adapt to these changing actions and guidelines. Beginning March 17, 2020, substantially all of the Company’s workforce began working from home. On April 6, manufacturing operations resumed at the Company’s facilities, with substantially all other staff continuing to work from home. While the direct effects of the stay-at-home orders and BioCardia’s work-from-home policies have been largely mitigated during the three months ended June 30, 2020, the overall impact of the pandemic has resulted in disruption to the Company’s business and resulted in delays in the Company’s development programs and regulatory and commercialization timelines. The overall magnitude of the continuing impact will depend, in part, on the length and severity of changing restrictions and other limitations on BioCardia’s ability to conduct the Company’s business. BioCardia’s future research and development expenses and general and administrative expenses may vary significantly if the Company experiences an increased impact from COVID-19 on the costs and timing associated with the conduct of BioCardia’s clinical trials and other related business activities.

8

BioCardia’s ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic.

(b)	Liquidity and Other Risks and Uncertainties
	Going Concern and Liquidity - The Company has incurred net losses and negative cash flows from operations since its inception and had an accumulated deficit of $109.2 million as of June 30, 2020. Management expects operating losses and negative cash flows to continue through at least the next several years. The Company expects to incur increasing costs as the pivotal CardiAMP Heart Failure trial is advanced and development of the CardiAMP and CardiALLO Cell Therapy Systems continue. Therefore, absent additional funding, management believes cash and cash equivalents of $11.1 million as of June 30, 2020 are not sufficient to fund the Company beyond the second quarter of 2021. 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 the second quarter of 2021, 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, the Company may be required to reduce operating expenses, delay or reduce the scope of its product development programs, obtain funds through arrangements with others that may require the Company to relinquish rights to certain of its technologies or products that the Company would otherwise seek to develop or commercialize itself, 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, derivative instruments, clinical accruals, and inventory valuation.

(d)	Principles of Consolidation
	The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. 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 April 9, 2020 for the year ended December 31, 2019. There have been no changes to those policies.

9

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

(3) Fair Value Measurement

The fair value of financial instruments reflects the amounts that the Company estimates 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). The Company follows 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 June 30, 2020 and December 31, 2019 and indicates the fair value hierarchy utilized to determine such fair value (in thousands):

	As of June 30, 2020
	Level 1		Level 2		Level 3		Total
Assets:
Money market funds	$	10,335	$	—	$	—	$	10,335

	As of December 31, 2019
	Level 1		Level 2		Level 3		Total
Assets:
Money market funds	$	4,637	$	—	$	—	$	4,637

(4) Inventories

Inventories are stated at the lower of cost or net realizable value using the average cost method. Inventories consisted of the following (in thousands): 

	June 30,		December 31,
	2020		2019
Raw materials	$	—	$	—
Work in process		—		—
Finished goods		—		4
Total	$	—	$	4

Write downs for excess or expired inventory are based on management’s estimates of forecasted usage of inventories and are included in cost of goods sold. A significant change in the timing or level of demand for certain products as compared to forecasted amounts may result in recording additional write downs for excess or expired inventory in the future. Charges to cost of goods sold for inventory write-downs, reserve adjustments, scrap, shrinkage, and expired inventories totaled approximately $4,000 and $1,000 for the three and six months ended June 30, 2020, respectively. Charges to cost of goods sold for inventory write-downs, reserve adjustments, scrap, shrinkage, and expired inventories totaled approximately $78,000 and $80,000 for the three and six months ended June 30, 2019, respectively.

(5) Property and Equipment, Net

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

	June 30,			December 31,
	2020			2019
Computer equipment and software	$	134		$	132

Depreciation expense totaled approximately $22,000 and $36,000 for the three and six months ended June 30, 2020, respectively. Depreciation expense totaled approximately $26,000 and $49,000 for the three and six months ended June 30, 2019, respectively.

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

The Company’s operating lease is a property lease for its laboratory and corporate offices. BioCardia’s lease agreement does not contain any material residual guarantees or material restrictive covenants, nor does it contain an additional lease extension. The Company determines 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.

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. The Company 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. The Company has no finance leases.

The lease expense for the three and six months ended June 30, 2020, respectively, was $150,000 and $301,000. The lease expense for the three and six months ended June 30, 2019, respectively, was $150,000 and $301,000. The cash paid under the operating lease during the three and six months ended June 30, 2020, respectively, was $158,000 and $315,000. The cash paid under the operating lease during the three and six months ended June 30, 2019, respectively, was $153,000 and $306,000. At June 30, 2020, the weighted average remaining lease term was 1.5 years, and the weighted average discount rate was 12.05%.

Future minimum lease payments under the operating lease as of June 30, 2020 are as follows (in thousands):

	Operating Lease
	June 30, 2020
Remainder of 2020	$	315
For the year ending December 31, 2021		649
Total undiscounted lease payments		964
Less imputed interest		78
Total operating lease liabilities	$	886

Accrued clinical trial costs		754		519
Grant liability		622		630

Total	$	2,230	$	2,561

(8) Note payable under Paycheck Protection Program

Paycheck Protection Program - On May 1, 2020, BioCardia Lifesciences, Inc. (the “Borrower”), a wholly owned subsidiary of BioCardia, Inc. (the “Company”), entered into a promissory note (the “Note”) with Silicon Valley Bank (the “Lender”) evidencing an unsecured loan in the aggregate principal amount of $506,413 pursuant to the Paycheck Protection Program (the “PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration. All the funds under the Note were disbursed to the Borrower on May 1, 2020.

In accordance with the requirements of the CARES Act, the Borrower will use the proceeds from the Note in accordance with the requirements of the PPP to cover certain qualified expenses, including payroll costs, rent and utility costs. Interest accrues on the Note at the rate of 1.00% per annum. Under the terms of the agreement the accrued interest payable is approximately $1,000 at June 30, 2020. The Borrower may apply for forgiveness of amount due under the Note, in an amount equal to the sum of qualified expenses under the PPP, which include payroll costs, rent obligations, and covered utility payments incurred during the eight weeks following disbursement under the Note. On June 5, 2020, the Paycheck Protection Flexibility Act extended the period for qualifying expenses from eight weeks to an optional twenty-four-week period. The Borrower intends to use the entire proceeds under the Note for such qualifying expenses. 

Subject to any forgiveness under the PPP, the Note matures two years following the date of issuance of the Note and includes a period for the first six months during which time required payments of interest and principal are deferred. Beginning on the seventh month following the date of the Note, the Borrower is required to make 18 monthly payments of principal and interest. The Note may be prepaid at any time prior to maturity with no prepayment penalties. The Note provides for customary events of default, including, among others, those relating to breaches of the Borrower’s obligations under the Note, including a failure to make payments, any bankruptcy or similar proceedings involving the Borrower, and certain material effects on the Borrower’s ability to repay the Note.

(9) Stockholders’ Equity

2020 Public Offering on Form S-1 Registration Statement - In May 2020, the Company submitted a Form S-1 Registration Statement (S-1) to the Securities and Exchange Commission (SEC), which was subsequently amended. On June 17, 2020, the Company entered into an underwriting agreement with A.G.P./Alliance Global Partners, as representative of the several underwriters named therein, relating to a firm commitment underwritten public offering pursuant to the S-1, of 4,762,000 shares of common stock, par value of $0.001 per share. The offering price to the public was $2.10 per share. The underwriters were granted a 45-day option to purchase up to 714,190 additional shares of common stock to cover over-allotments. Such option was exercised in full on June 18, 2020. The closing of the offering occurred on June 19, 2020. After deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, BioCardia realized net proceeds of approximately $10.3 million.

(10) Share-Based Compensation

The share-based compensation expense is recorded in cost of goods sold, 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 months ended June 30, 2020 and 2019 was recorded as follows (in thousands):

	Three months ended June 30,				Six months ended June 30,
	2020		2019		2020		2019
Cost of goods sold	$	-	$	46	$	-	$	92
Research and development		318		251		731		494
Selling, general and administrative		337		399		865		800
Total share-based compensation	$	655	$	696	$	1,596	$	1,386

On January 29, 2020 (the “repricing date”), the Company’s Board of Directors repriced certain previously granted and still outstanding vested and unvested stock option awards held by employees, executives and certain service providers of the Company; as a result, the exercise price was lowered to $5.32 per share. No other terms of the repriced stock options were modified, and the repriced stock options will continue to vest according to their original vesting schedules and will retain their original expiration dates. As a result of the repricing, 515,036 vested and unvested stock options outstanding with original exercise prices ranging from $10.05 to $97.21, were repriced.

The repricing on January 29, 2020 resulted in incremental stock-based compensation expense of $569,000, of which $412,000 related to vested employee stock option awards and was expensed on the repricing date, and $157,000 related to unvested stock option awards and is being amortized on a straight-line basis over the approximately three year remaining weighted average vesting period of those awards.

 Unrecognized share-based compensation for employee and nonemployee options granted through June 30, 2020 is approximately $3.1 million to be recognized over a remaining weighted average service period of 2.3 years.

Share-Based Compensation (RSUs)

The following summarizes the activity of non-vested RSUs:  

	Number of shares			Weighted average grant date fair value per share
Balance, December 31, 2019		36,981		$	10.56
RSUs granted		315,296			4.12
RSUs vested		(94,796	)		6.02
RSUs forfeited		(56,161	)		3.75
Balance, June 30, 2020		201,320		$	1.46

Unrecognized share-based compensation for employee and nonemployee RSUs granted through June 30, 2020 is approximately $208,000 to be recognized over a remaining weighted average service period of 2.0 years.

During the three months ended June 30, 2020, the Company granted to certain members of management 113,976 restricted stock units, or RSUs, to settle bonuses earned during the year ended December 31, 2019.

During the three months ended June 30, 2020 the Company granted 122,997 RSUs to board members to settle $613,000 of board compensation earned in three months ended June 30, 2018 through the three months ended March 31, 2020.  The associated compensation expense was recognized when earned in the previous periods. On June 30, 2020, the Company also granted 23,123 RSUs to board members and recognized the $55,000 in stock compensation expense for board service for the three months ended June 30, 2020. The number of RSUs granted each quarter is calculated based on $92,500 divided by the greater of $4 or the closing share price of the Company’s common stock on the last trading day of the fiscal quarter. These RSUs represent a contingent right to receive one share of common stock, but for which delivery of the stock will occur on the earlier of the two year anniversary of the grant, the board member’s separation from the Company, a change in control as defined by the 2016 Equity Incentive Plan or the board member’s death. 

During the three months ended June 30, 2020, the Company issued 29,625 shares of common stock to two former board members to settle $148,000 of board compensation obligations.

(11) Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. 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. 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 its 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: 

	June 30,
	2020		2019
Stock options to purchase common stock		1,055,203		618,366
Unvested restricted stock units		78,323		27,426
Common stock warrants		2,435,807		296,296
Total		3,569,333		942,088

(12) Income Taxes

During the three and six months ended June 30, 2020 and 2019, there was no income tax expense or benefit for federal or state income taxes in the accompanying condensed consolidated statement of operations due to the Company’s net loss and a full valuation allowance on the resulting deferred tax assets.

As of June 30, 2020, 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. 

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. Given the Company’s historic tax losses, no benefit is expected as a result of the CARES Act; however, the Company will continue to evaluate the impact of the CARES Act. 

On May 3, 2020, the Company received loan proceeds of $506,000 as part of the Paycheck Protection Program from the CARES Act. The Company believes it will qualify for loan forgiveness and the application is expected to be submitted in the third quarter. The Company will continue to evaluate the impact.

Overview

We are a clinical-stage regenerative medicine company developing novel therapeutics for cardiovascular and pulmonary diseases with large unmet medical needs. CardiAMP and CardiALLO cell therapies are the Company’s biotherapeutic product candidates in clinical development. 

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 allogenic cell therapy, derived from donor cells and provided “off the shelf”, is also being advanced for two indications, heart failure as CardiALLO cell therapy (BCDA-03) and for the pulmonary indication of acute respiratory distress that has developed from COVID-19 (BCDA-04).

The Company's approved products include the Helix™ transendocardial delivery system and its steerable guide and sheath catheter portfolio. BioCardia partners with other biotherapeutic companies to provide its Helix System and clinical support.

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. We have also generated modest revenues from sales of our approved products. We have funded our operations primarily through the sales of equity and convertible debt securities, and certain government and private grants.

We have incurred net losses in each year since our inception. Our net losses were approximately $3.6 million and $8.2 million for the three and six months ended June 30, 2020, respectively. Our net losses were approximately $3.8 million and $7.4 million for the three and six months ended June 30, 2019, respectively. As of June 30, 2020, we had an accumulated deficit of approximately $109.2 million. Substantially all our net losses have resulted from costs incurred in connection with our research and development programs, clinical trials, intellectual property matters, building our manufacturing and sales capabilities, and from general and administrative costs associated with our operations. As discussed in more detail under “Liquidity and Capital Resources”, there is substantial doubt about our ability to continue as a going concern within one year after the date this Quarterly Report on Form 10-Q is filed with the SEC, and we plan to raise additional capital, potentially including debt and equity arrangements, to finance our future operations. There can be no assurances as to the availability of capital or the terms on which capital will be available, if at all.

CardiAMP Cell Therapy

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 this indication (BCDA-01).

The ongoing CardiAMP Heart Failure trial is active at 24 clinical sites and 77 patients have been enrolled to date. The independent Data Safety Monitoring Board (DSMB) completed a prespecified data review in March 2020, which included the safety follow-up results available for these patients. From this review, the DSMB indicated there were no safety concerns with the study results and recommended that the trial continue as planned.

We anticipate another prespecified DSMB interim readout from the trial in the fourth quarter of 2020 on all patients enrolled at that time point, which will include a futility analysis on the 60 patients that will have reached one-year follow-up.  This fourth quarter of 2020 event is anticipated to be the first randomized data set including the primary efficacy endpoint reviewed by the DSMB. 

We are continuing to assess the impact of COVID-19 on the enrollment in the CardiAMP Heart Failure Trial. Some of our clinical centers stopped performing elective procedures and advised us that they would not be performing elective procedures until restrictions on elective procedures are lifted.  Many centers also delayed patient follow-up visits out of concern for patient exposure to COVID-19.  In alignment with recent FDA guidance on clinical trials, “FDA Guidance on Conduct of Clinical Trials of Medical Products during COVID-19 Pandemic Guidance for Industry, Investigators, and Institutional Review Boards”, we have taken steps to address unavoidable protocol deviations due to COVID-19 illness and/or COVID-19 control measures. Clinical sites remain engaged and some have resumed elective procedures, including enrollment activities in our trial. A number of consented and qualified patients are scheduled for treatment in the weeks ahead.

The FDA has approved a second IDE for the randomized controlled pivotal trial of the CardiAMP Cell Therapy System in patients with refractory chronic myocardial ischemia (BCDA-02) for up to 343 patients at up to 40 clinical sites in the United States. 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. We anticipate that many of the investigators and sites will be the same for both the heart failure and chronic myocardial ischemia indications. As of the date of this filing, the first clinical site has been activated and we are working towards initial patient enrollment and to add additional centers. 

The Department of Health & Human Services Centers for Medicare & Medicaid Services, or CMS, has designated that both the CardiAMP Heart Failure Trial and the CardiAMP Chronic Myocardial Ischemia Trial qualify for Medicare national coverage. Covered costs include patient screening, the CardiAMP Cell Therapy System and procedure, and clinical follow-up at one and two years after the procedure.  Private insurance plans covering 50 million insured Americans follow this CMS reimbursement policy and are similarly anticipated to cover these costs.  This coverage significantly reduces our cost of conducting these pivotal trials.  

ALLOGENIC Cell Therapy for Cardiac and Pulmonary Disease

Our second therapeutic platform is our investigational culture expanded bone marrow derived allogenic or “off the shelf” mesenchymal cell therapy being advanced for cardiac and pulmonary disease. These are the Company’s Neurokinin 1 Receptor Positive Mesenchymal Stem Cells (NK1R+ MSC).

We are actively working to secure FDA acceptance of an Investigational New Drug (“IND”) application for a Phase I/II trial for CardiALLO Cell Therapy System for the treatment of ischemic systolic heart failure (BCDA-03). To date we have completed manufacturing validation runs of these cells at BioCardia to support future clinical studies as well as preclinical animal data and have received written input from the FDA on the protocol design and the chemistry manufacturing and controls. The Company submitted its detailed response to the FDA addressing their comments and questions and received confirmation the FDA received this submission on July 2, 2020. We have received communications from the FDA and are working through their questions. We hope to receive acceptance of the IND soon, a critical step to beginning the trial.

The Company also intends to submit an IND for the use of its allogenic cell therapy for Acute Respiratory Distress Syndrome (ARDS) caused by COVID-19. Based on preliminary clinical reports on COVID-19, respiratory failure complicated by ARDs is the leading cause of death for COVID-19 patients. ARDS is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs.

18

Helix™ Biotherapeutic Delivery System

We believe our Helix Biotherapeutic Delivery System or “Helix” is the leading percutaneous catheter delivery system for cardiovascular regenerative medicine. It enables investigational studies of local delivery of cell and gene-based therapies, including CardiAMP and CardiALLO cell therapies to treat cardiovascular indications. Helix is in use or has potential to be used to treat many cardiac diseases including heart failure with reduced ejection fraction, heart failure with preserved ejection fraction, obstructive hypertrophic cardiomyopathy, myocardial infarction, chronic myocardial ischemia, and cardiac conduction disorders. The Helix’s small hollow, distal helical needle is advanced, similar to an angioplasty catheter, and is passed over the aortic arch and across the aortic valve through our Morph guide catheter or “Morph”. The Helix is then advanced from within the Morph, and its helical needle is rotated into the heart tissue to provide active fixation during therapeutic delivery, similar to the active fixation electrodes used in cardiac pacing. This fixation to the beating heart wall provides for stability and control during the delivery procedure. It uses simplified fluoroscopic imaging, crosses the aortic arch and valve over a guide wire, and provides the operator with three degrees of freedom to maximize operator control. The Helix is approved in Europe with CE Mark and is under investigational use in the United States and is being used in pre-clinical and clinical investigations of cell, gene, and protein therapies.  

Morph Deflectable Guide and Sheaths Product

Our Morph catheter is designed to enable physicians to navigate through tortuous anatomy, customize the shape of the catheter to the patient’s anatomy and their clinical needs during the procedure, and to have stellar back up support once positioned. Morph catheters enable all Helix procedures and have been commercially available to treat more than ten thousand patients. A number of Morph guides and sheaths are approved for commercial sale in the United States, including the AVANCE™ steerable introducer and the Morph DNA guide. Certain Morph catheter systems are approved in Europe with CE Mark. We anticipate broader commercial availability of the AVANCE steerable introducer in the fourth quarter of 2020 and utilization of Morph DNA in our CardiAMP and CardiALLO clinical programs.

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.

Cost of Goods Sold

Cost of goods sold includes the costs of raw materials and components, manufacturing personnel and facility costs and other indirect and overhead costs associated with manufacturing our commercial enabling and delivery products, which generate net product revenue.

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.

19

We plan to increase our research and development expenses for the foreseeable future as we continue the pivotal CardiAMP Heart Failure Trial, advance the pivotal CardiAMP Chronic Myocardial Ischemia Trial, further develop our autologous and allogenic cell therapy candidates. 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.

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, cash equivalents and investments, and interest charges we incurred in periods during 2019 when we had convertible debt outstanding. 

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 generally accepted accounting principles in the United States. The preparation of our financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities. 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. 

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 2 in our Annual Report on Form 10-K for the year ended December 31, 2019, filed April 9, 2020.

 Revenue.    Revenue decreased to $27,000 in the second quarter of 2020 as compared to $86,000 in the second quarter of 2019, due to reduced volumes of commercial catheter sales as a part of the planned transition to the new AVANCE and Morph DNA product families. Revenue decreased to $65,000 in the six months ended June 30, 2020 as compared to $302,000 in the six months ended June 30, 2019 primarily due to the reduced volumes of commercial catheter sales coupled with lower revenue generating partnering activities during the period.  We expect collaboration agreement revenue to increase modestly in 2020, depending on the timing and progress of existing collaborative programs of our partners and the initiation of new partnering relationships anticipated later in the year. Net product revenue is expected to be limited in 2020 and will be subject to customer demand, production resource availability for the new product families, the timing of FDA clearance for market release of different models and sizes and the resumption of medical procedures by our health care provider customers that have been adversely impacted by the response to the COVID-19 pandemic.

Cost of Goods Sold.    Cost of goods sold decreased $191,000 in the second quarter of 2020 as compared to the second quarter of 2019 and decreased $293,000 in the six months ended June 30, 2020 compared to June 30, 2019, due primarily to the decrease in net product sales volumes coupled with the increase in raw material inventory reserves in 2019 related to transitioning to production of the new AVANCE™ product family. We expect cost of goods sold to be limited in 2020 depending on the timing and demand for the new product family introductions.

Research and Development Expenses.   Research and development expenses increased by approximately $5,000 during the second quarter of 2020 as compared to the second quarter of 2019 and by $625,000 in the six months ended June 30, 2020 as compared to June 30, 2019, primarily due to expenses incurred in the execution of the pivotal CardiAMP Heart Failure Trial, development of the CardiALLO Cell Therapy System and our other therapeutic programs, including fees paid to consultants, contract research organizations, additional personnel costs and increased stock compensation expense including the January 29, 2020 option repricing. We expect research and development expenses to increase modestly year over year in 2020 as we advance the CardiAMP Heart Failure Trial and we further develop the BioCardia autologous and allogenic cell therapies.

Selling, General and Administrative Expenses.   Selling, general and administrative expenses for the second quarter of 2020 decreased by approximately $61,000 compared to the second quarter of 2019, due primarily to expenses incurred in 2019 associated with the reverse stock split and subsequent up listing to the Nasdaq Capital Market. Selling, general and administrative expenses in the six months ended June 30, 2020 increased by $164,000 as compared to the six months ended June 30, 2019 primarily due to increased stock compensation, including the January 29, 2020 repricing, coupled with increased insurance premiums and professional service fees, partially offset by the expenses incurred in 2019 associated with the reverse stock split and up listing. We expect selling, general and administrative expenses to decrease modestly year over year for the remainder of 2020.

21

Liquidity and Capital Resources

We have incurred net losses each year since our inception and as of June 30, 2020, we had an accumulated deficit of approximately $109.2 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 and equity securities as well as the cash acquired through our reverse merger transaction that was completed on October 24, 2016, $3.8 million raised from the sale of unregistered securities on December 24, 2018, the $625,000 raised from convertible notes that were issued in July 2019 and that converted in August 2019, the $9.27 million in net proceeds raised from the sale of common stock and warrants in August and September 2019, the $506,000 raised from a promissory note in May 2020 and the $10.3 million in net proceeds raised from the sale of common stock in June 2020. As of June 30, 2020, we had cash and cash equivalents of approximately $11.1 million. 

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

	Six months ending June 30,
	2020			2019
Net cash used in:
Operating activities	$	(5,336	)	$	(4,717	)
Investing activities		(9	)		(124	)
Financing activities		10,846			-
Net decrease in cash and cash equivalents	$	5,501		$	(4,841	)

Cash Flows from Operating Activities. The increase in overall spending for operating activities of $619,000 through the second quarter of 2020 compared to the second quarter of 2019 related primarily to increases in payments to third parties involved in our clinical trial and increased professional fees and insurance premiums. We expect spending to increase modestly as we advance the CardiAMP Heart Failure Trial and further develop our therapeutic programs.

Cash Flows from Investing Activities. Net cash used in investing activities of $9,000 through the second quarter of 2020 consisted primarily of purchases of office and lab equipment. Net cash used in investing activities of $124,000 through the second quarter of 2019 consisted primarily of purchases of lab equipment and clean room environmental systems.

Cash Flows from Financing Activities. Net cash provided by financing activities of $10.8 million during the six months ended June 30, 2020 consisted of $11.5 million in gross proceeds from the sale of common stock in June 2020 less issuance costs of $1.2 million and $506,000 proceeds from the Note (as defined below). There was no net cash provided by financing activities through the second quarter of 2019.

PPP Loan

On May 1, 2020, BioCardia Lifesciences, Inc., our wholly owned subsidiary, entered into a promissory note (the “Note”) with Silicon Valley Bank (the “Lender”) evidencing an unsecured loan in the aggregate principal amount of $506,413 pursuant to the Paycheck Protection Program (the “PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration. All the funds under the Note were disbursed to us on May 1, 2020.

In accordance with the requirements of the CARES Act, we intend to use the proceeds from the Note in accordance with the requirements of the PPP to cover certain qualified expenses, including payroll costs, rent and utility costs. Interest accrues on the Note at the rate of 1.00% per annum. We may apply for forgiveness of amount due under the Note, in an amount equal to the sum of qualified expenses under the PPP, which include payroll costs, rent obligations, and covered utility payments incurred during the eight weeks following disbursement under the Note. On June 5, 2020, the Paycheck Protection Flexibility Act extended the period for qualifying expenses from eight weeks to an optional twenty-four-week period. We intend to use the entire proceeds under the Note for such qualifying expenses.

Subject to any forgiveness under the PPP, the Note matures two years following the date of issuance of the Note and includes a period for the first six months during which time required payments of interest and principal are deferred. Beginning on the seventh month following the date of the Note, the Borrower is required to make 18 monthly payments of principal and interest. The Note may be prepaid at any time prior to maturity with no prepayment penalties.

2020 Public Offering of Common Stock

In May 2020, the Company submitted a Form S-1 Registration Statement (S-1) to the Securities and Exchange Commission (SEC), which was subsequently amended. On June 17, 2020, the Company entered into an underwriting agreement with A.G.P./Alliance Global Partners, as representative of the several underwriters named therein, relating to a firm commitment underwritten public offering pursuant to the S-1, of 4,762,000 shares of common stock, par value of $0.001 per share. The offering price to the public was $2.10 per share. The underwriters were granted a 45-day option to purchase up to 714,190 additional shares of common stock to cover over-allotments. Such option was exercised in full on June 18, 2020. The closing of the offering occurred on June 19, 2020. After deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, BioCardia realized net proceeds of approximately $10.3 million.

Future Funding Requirements

To date, we have generated modest revenue from sales of our approved products. 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 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 $11.1 million as of June 30, 2020 is not sufficient to fund our operations beyond the second quarter of 2021. In order to continue to further the development of our lead therapeutic candidates beyond the second quarter of 2021, we will need to raise additional capital. We plan to raise additional capital, potentially including debt and equity arrangements, to finance our future operations. 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 clinical trials and related development programs;

• FDA acceptance of our autologous and allogenic therapies for heart failure and other 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; and

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

23

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 stock holders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stock holders. 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 and for the three and six months ended June 30, 2020 have been prepared on the basis that we 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 our 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. BioCardia’s ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and the continuing disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic. 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 we have a viable 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 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 financial statements.

Nasdaq Delisting Notice and Subsequent Compliance

On April 15, 2020, we received written notice from The Nasdaq Stock Market LLC (“Nasdaq”) notifying us that, based on our stockholders’ equity of $2.37 million as of December 31, 2019, we were not in compliance with the minimum stockholders’ equity requirement of $2.5 million for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1).

On May 28, 2020 we provided Nasdaq with our specific plan to achieve and sustain compliance with the foregoing listing requirement. On June 2, 2020 Nasdaq accepted the plan and granted an extension to regain compliance on or before October 12, 2020. On June 19, 2020, the Company completed the sale and issuance of an aggregate of 5,476,190 shares of common stock pursuant to the Company’s registration statement on Form S-1 (File No. 333-236404), resulting in net proceeds of approximately $10.3 million (the “Public Offering”). As of June 30, 2020, the Company believes it has regained compliance with the minimum stockholders’ equity requirement of $2.5 million for continued listing on the Nasdaq Capital Market under Nasdaq Listing Rule 5550(b)(1) as a result of the Public Offering.

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 June 30, 2020.

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 June 30, 2020, 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 June 30, 2020, 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 June 30, 2020, our disclosure controls and procedures were, in design and operation, not effective at a reasonable assurance level as a result of the material weakness described below.

Status of Material Weakness

We identified the following material weakness in our internal control over financial reporting during the year ended December 31, 2019:

● The material weakness resulted from a lack of sufficient technical resources to appropriately perform effective and timely review of the accounting for and disclosure of complex non-routine transactions, including the adoption of new accounting standards; and

● The material weakness remains unremediated as of June 30, 2020.

Management has implemented measures designed to improve our internal control over financial reporting and remediate the material weakness, including the following:

● We have enhanced our control processes for identifying and reviewing non-routine transactions, including formalized reviews of these transactions by senior accounting management and more robust documentation of the related conclusions, and required accounting; and 

● We have engaged external consultants to provide expertise and assistance sufficient to evaluate, resolve and document the accounting for complex non-routine transactions and continue to do so on an ongoing basis. 

25

Management believes that the measures implemented above will provide an appropriate remediation of the material weakness. However, the material weakness will not be considered remediated until the applicable controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively. The Company expects that the remediation of this material weakness will be completed prior to December 31, 2020.

We cannot assure you that the measures we are taking will be sufficient to remediate this material weakness or to avoid potential future material weaknesses. If our efforts are not successful, or other material weaknesses or control deficiencies occur in the future, we may be unable to report our financial results accurately on a timely basis, which could cause our reported financial results to be materially misstated and result in the loss of investor confidence and cause the market price of our common stock to decline.

Changes in Internal Control over Financial Reporting

Other than the material weakness described in this Item 4, 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 June 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

26

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We 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 we are a party to any material legal proceedings, except as described below. We currently do not expect the proceedings described below to have a material adverse effect on our business, financial position, results of operations, or cash flows at this time. Regardless of the outcome, proceedings such as these can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors. There can be no assurance that existing or future legal proceedings arising in the ordinary course of business or otherwise will not become material or have a material adverse effect on our business, financial position, results of operations, or cash flows.

We have a legal proceeding currently pending under 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”). The Litigation relates to matters we raised in a letter to Ms. Surbhi Sarna, nVision Medical and Boston Scientific based on BioCardia’s discovery in January 2019 that Ms. Sarna had assigned to a company she founded, nVision Medical, a patent and patent applications she had filed while a BioCardia employee. nVision subsequently was acquired by Boston Scientific. BioCardia made various claims, including that the patent and patent application rightfully belonged to BioCardia pursuant to Ms. Sarna’s invention assignment agreement, that the proceeds from the sale of nVision to Boston Scientific rightfully belonged to BioCardia because they were the direct result of Ms. Sarna’s breach of her obligation to assign to BioCardia the patent and patent applications and the use of misappropriated BioCardia trade secrets. On September 6, 2019, Boston Scientific Corporation, Boston Scientific Scimed Inc, and Fortis Advisors LLC (the “Boston Scientific Parties”) filed a complaint against BioCardia in the United States District Court Northern District of California, Case no. 3:19-05645-VC, seeking declarations that the claims made in BioCardia’s correspondence were without basis. On October 31, 2019, BioCardia filed a counterclaim against the Boston Scientific Parties and Ms. Sarna for breach of contract, misappropriation of trade secrets and correction of inventorship on the patents naming Ms. Sarna as an inventor. BioCardia seeks imposition of constructive trusts both on the patents naming Ms. Sarna as an inventor and the proceeds received from the sale of nVision to Boston Scientific, as well as damages, including unjust enrichment damages measured by the proceeds received from the sale of nVision to Boston Scientific. On April 9, 2020, we entered into a Litigation Funding Agreement with BSLF, L.L.C., an entity owned and controlled by Andrew Blank, a member of our board of directors, for the purpose of funding the Litigation.

On April 23, 2020, the Company filed a complaint against nVision Medical Corporation arising out of the same transaction as its counterclaims in the case filed by Boston Scientific. On April 29, 2020 Judge Vincent Chhabria, the Judge who is presiding over the Boston Scientific case, determined that the nVision case is “related to” the case filed by Boston Scientific and accordingly reassigned the nVision case to himself.

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, 2019 and our Quarterly Report on Form 10-Q for the three months ended March 31, 2020, 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, 2019, and our Quarterly Report on Form 10-Q for the three months ended March 31, 2020 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.  

27

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

In June 2020, we issued 29,625 shares of common stock in private placement transactions exempt from registration under the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) of that act. We issued the shares to two former members of our Board of Directors to settle board compensation obligations.

Significant Accounting Policies [Text Block]

( 2 ) Significant Accounting Policies

(a)	Basis of Preparation
	The accompanying condensed consolidated balance sheets, statements of operations, shareholders' equity, and cash flows as of June 30, 2020 and for the three and six months ended June 30, 2020 and 2019 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 June 30, 2020, results of operations for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ended December 31, 2020 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, 2019, filed with the SEC on April 9, 2020.  The results for the three months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or for any other interim period or for any other future year, particularly in light of the novel coronavirus pandemic, or COVID- 19, and its impact on domestic and global economies. To limit the spread of COVID- 19, governments have taken various actions including the issuance of stay-at-home orders and social distancing guidelines, causing some businesses to suspend operations and/or experience a reduction in demand for many products from direct or ultimate customers. Accordingly, businesses have adjusted, reduced or suspended operating activities and are continuing to adapt to these changing actions and guidelines. Beginning March 17, 2020, substantially all of the Company's workforce began working from home. On April 6, manufacturing operations resumed at the Company's facilities, with substantially all other staff continuing to work from home. While the direct effects of the stay-at-home orders and BioCardia's work-from-home policies have been largely mitigated during the three months ended June 30, 2020, the overall impact of the pandemic has resulted in disruption to the Company's business and resulted in delays in the Company's development programs and regulatory and commercialization timelines. The overall magnitude of the continuing impact will depend, in part, on the length and severity of changing restrictions and other limitations on BioCardia's ability to conduct the Company's business. BioCardia's future research and development expenses and general and administrative expenses may vary significantly if the Company experiences an increased impact from COVID- 19 on the costs and timing associated with the conduct of BioCardia's clinical trials and other related business activities.

BioCardia's ability to raise additional funds

may

be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-

19

pandemic.

(b)	Liquidity and Other Risks and Uncertainties
	Going Concern and Liquidity - The Company has incurred net losses and negative cash flows from operations since its inception and had an accumulated deficit of $109.2 million as of June 30, 2020. Management expects operating losses and negative cash flows to continue through at least the next several years. The Company expects to incur increasing costs as the pivotal CardiAMP Heart Failure trial is advanced and development of the CardiAMP and CardiALLO Cell Therapy Systems continue. Therefore, absent additional funding, management believes cash and cash equivalents of $11.1 million as of June 30, 2020 are not sufficient to fund the Company beyond the second quarter of 2021. 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 the second quarter of 2021, 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, the Company may be required to reduce operating expenses, delay or reduce the scope of its product development programs, obtain funds through arrangements with others that may require the Company to relinquish rights to certain of its technologies or products that the Company would otherwise seek to develop or commercialize itself, 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, derivative instruments, clinical accruals, and inventory valuation.

(d)	Principles of Consolidation
		The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary. 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 April 9, 2020 for the year ended December 31, 2019. There have been no changes to those policies.

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

Fair Value Disclosures [Text Block]

( 3 ) Fair Value Measurement

The fair value of financial instruments reflects the amounts that the Company estimates 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). The Company follows 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

June 30, 2020

and

December 31, 2019

Lessee, Operating Leases [Text Block]

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

The Company's operating lease is a property lease for its laboratory and corporate offices. BioCardia's lease agreement does

not

contain any material residual guarantees or material restrictive covenants, nor does it contain an additional lease extension. The Company determines 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.

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. The Company 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. The Company has

no

finance leases.

The lease expense for the

three

and

six

months ended

June 30, 2020,

respectively, was

$150,000

and

$301,000.

The lease expense for the

( 8 ) Note payable under Paycheck Protection Program

Paycheck Protection Program

- On

May 1, 2020,

BioCardia Lifesciences, Inc. (the “Borrower”), a wholly owned subsidiary of BioCardia, Inc. (the “Company”), entered into a promissory note (the “Note”) with Silicon Valley Bank (the “Lender”) evidencing an unsecured loan in the aggregate principal amount of

$506,413

pursuant to the Paycheck Protection Program (the “PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration. All the funds under the Note were disbursed to the Borrower on

May 1, 2020.

In accordance with the requirements of the CARES Act, the Borrower will use the proceeds from the Note in accordance with the requirements of the PPP to cover certain qualified expenses, including payroll costs, rent and utility costs. Interest accrues on the Note at the rate of

1.00%

per annum. Under the terms of the agreement the accrued interest payable is approximately

$1,000

at

June 30, 2020.

The Borrower

may

apply for forgiveness of amount due under the Note, in an amount equal to the sum of qualified expenses under the PPP, which include payroll costs, rent obligations, and covered utility payments incurred during the

eight

weeks following disbursement under the Note. On

June 5, 2020,

the Paycheck Protection Flexibility Act extended the period for qualifying expenses from

eight

weeks to an optional

twenty-four

-week period. The Borrower intends to use the entire proceeds under the Note for such qualifying expenses. 

Subject to any forgiveness under the PPP, the Note matures

two

years following the date of issuance of the Note and includes a period for the

first

six

months during which time required payments of interest and principal are deferred. Beginning on the

seventh

month following the date of the Note, the Borrower is required to make

18

monthly payments of principal and interest. The Note

may

be prepaid at any time prior to maturity with

no

prepayment penalties. The Note provides for customary events of default, including, among others, those relating to breaches of the Borrower's obligations under the Note, including a failure to make payments, any bankruptcy or similar proceedings involving the Borrower, and certain material effects on the Borrower's ability to repay the Note.

On

January 29, 2020 (

the “repricing date”), the Company's Board of Directors repriced certain previously granted and still outstanding vested and unvested stock option awards held by employees, executives and certain service providers of the Company; as a result, the exercise price was lowered to

$5.32

per share.

No

other terms of the repriced stock options were modified, and the repriced stock options will continue to vest according to their original vesting schedules and will retain their original expiration dates. As a result of the repricing,

515,036

vested and unvested stock options outstanding with original exercise prices ranging from

$10.05

to

$97.21,

were repriced.

The repricing on

January 29, 2020

resulted in incremental stock-based compensation expense of

$569,000,

of which

$412,000

related to vested employee stock option awards and was expensed on the repricing date, and

$157,000

related to unvested stock option awards and is being amortized on a straight-line basis over the approximately

three

year remaining weighted average vesting period of those awards.

Notes to Financial Statements

Earnings Per Share [Text Block]

( 1 1 ) Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. 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. 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 its 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:

( 1 2 ) Income Taxes

During the

three

and

six

months ended

June 30, 2020

and

2019,

there was

no

income tax expense or benefit for federal or state income taxes in the accompanying condensed consolidated statement of operations due to the Company's net loss and a full valuation allowance on the resulting deferred tax assets.

As of

June 30, 2020,

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. 

On

March 27, 2020,

the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the COVID-

19

pandemic. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset

100%

of taxable income for taxable years beginning before

2021.

In addition, the CARES Act allows NOLs incurred in

2018,

2019,

and

2020

to be carried back to each of the

five

preceding taxable years to generate a refund of previously paid income taxes. Given the Company's historic tax losses,

no

benefit is expected as a result of the CARES Act; however, the Company will continue to evaluate the impact of the CARES Act. 

On

May 3, 2020,

the Company received loan proceeds of

$506,000

as part of the Paycheck Protection Program from the CARES Act. The Company believes it will qualify for loan forgiveness and the application is expected to be submitted in the

third

quarter. The Company will continue to evaluate the impact.

Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of Accounting, Policy [Policy Text Block]

(a)	Basis of Preparation
	The accompanying condensed consolidated balance sheets, statements of operations, shareholders' equity, and cash flows as of June 30, 2020 and for the three and six months ended June 30, 2020 and 2019 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 June 30, 2020, results of operations for the three and six months ended June 30, 2020 and 2019, and cash flows for the six months ended June 30, 2020 and 2019. The results for the three and six months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ended December 31, 2020 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, 2019, filed with the SEC on April 9, 2020.  The results for the three months ended June 30, 2020 are not necessarily indicative of the results to be expected for the year ending December 31, 2020 or for any other interim period or for any other future year, particularly in light of the novel coronavirus pandemic, or COVID- 19, and its impact on domestic and global economies. To limit the spread of COVID- 19, governments have taken various actions including the issuance of stay-at-home orders and social distancing guidelines, causing some businesses to suspend operations and/or experience a reduction in demand for many products from direct or ultimate customers. Accordingly, businesses have adjusted, reduced or suspended operating activities and are continuing to adapt to these changing actions and guidelines. Beginning March 17, 2020, substantially all of the Company's workforce began working from home. On April 6, manufacturing operations resumed at the Company's facilities, with substantially all other staff continuing to work from home. While the direct effects of the stay-at-home orders and BioCardia's work-from-home policies have been largely mitigated during the three months ended June 30, 2020, the overall impact of the pandemic has resulted in disruption to the Company's business and resulted in delays in the Company's development programs and regulatory and commercialization timelines. The overall magnitude of the continuing impact will depend, in part, on the length and severity of changing restrictions and other limitations on BioCardia's ability to conduct the Company's business. BioCardia's future research and development expenses and general and administrative expenses may vary significantly if the Company experiences an increased impact from COVID- 19 on the costs and timing associated with the conduct of BioCardia's clinical trials and other related business activities.

BioCardia's ability to raise additional funds

may

be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-

19

pandemic.

Going Concern and Liquidity [Policy Text Block]

(b)

Liquidity and Other Risks and Uncertainties

   

Going Concern and Liquidity

- The Company has incurred net losses and negative cash flows from operations since its inception and had an accumulated deficit of

$109.2

million as of

June 30, 2020.

Management expects operating losses and negative cash flows to continue through at least the next several years. The Company expects to incur increasing costs as the pivotal CardiAMP Heart Failure trial is advanced and development of the CardiAMP and CardiALLO Cell Therapy Systems continue. Therefore, absent additional funding, management believes cash and cash equivalents of

$11.1

million as of

June 30, 2020

are

not

sufficient to fund the Company beyond the

second

quarter of

2021.

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 the

second

quarter of

2021,

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, the Company

may

be required to reduce operating expenses, delay or reduce the scope of its product development programs, obtain funds through arrangements with others that

may

require the Company to relinquish rights to certain of its technologies or products that the Company would otherwise seek to develop or commercialize itself, 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, derivative instruments, clinical accruals, and inventory valuation.

Consolidation, Policy [Policy Text Block]
