Royalty Agreement

On January 24, 2011, the Company entered into an Asset Purchase Agreement with Arthrex (the "Arthrex Asset Purchase Agreement"), pursuant to which the Company agreed to sell the assets of its joint arthroplasty division, referred to as the Reconstructive Division, to Arthrex. The Arthrex Asset Purchase Agreement also provided for the Company to receive royalty payments equal to 5% of net salesfiling of the Company's products made by Arthrex on a quarterly basis for a term up to and including the 20th anniversary of the June 10, 2011 closing date. These amounts were reflected as royalty income on the accompanying condensed consolidated statements of income.

On May 5, 2016, the Company entered into a Royalty Settlement and Release Agreement (the "Royalty Settlement and Release Agreement") with Arthrex, whereby Arthrex agreed to pay the Company $5,642,302 (the "Royalty Payment") in full satisfaction of all amounts due or payable, or which could become payable under the Arthrex Asset Purchase Agreement. Of the Royalty Payment, $142,302 of the amount represented royalty income due to the Company under the Arthrex Asset Purchase Agreement through the date of the Royalty Settlement and Release Agreement, and the remaining $5,500,000 represented the settlement of future royalties. The Royalty Settlement and Release Agreement became effective on July 1, 2016 upon the receipt of the Royalty Payment.

Use of Estimates

Financial statements prepared in accordance with U.S. GAAP require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Among other things, management makes estimates relating to share- based payments and deferred income tax assets. Actual results could differ from those estimates.

Revenue Recognition

The Company's revenue consists of royalty income from Arthrex pursuant to the Arthrex Asset Purchase Agreement. Royalty income is recognized as the amount becomes known and collectability is reasonably assured.

Net Income Per Share

Basic net income per share is computed by using the weighted-average number of common shares outstanding during the period. Diluted net income per share is computed giving effect to all dilutive potential common shares using various methods such as the treasury stock or modified treasury stock method in the determination of diluted shares outstanding at each reporting period. Dilutive potential common shares consist of incremental common shares issuable upon exercise of stock options. No dilutive potential common shares are included in the computation of any diluted per share amount because their impact was anti-dilutive.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The likelihood of realizing the tax benefits related to a potential deferred tax asset is evaluated, and a valuation allowance is recognized to reduce that deferred tax asset if it is more likely than not that all or some portion of the deferred tax asset will not be realized. Deferred tax assets and liabilities are calculated at the beginning and end of the year; the change in the sum of the deferred tax asset, valuation allowance and deferred tax liability during the year generally is recognized as a deferred tax expense or benefit. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date.

5

The Company evaluates the accounting for uncertainty in income tax recognized in its financial statements and determines whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities before any part of the benefit is recorded in its financial statements. For those tax positions where it is "not more likely than not" that a tax benefit will be sustained, no tax benefit is recognized. Where applicable, associated interest and penalties are also recorded. The Company has not accrued for any such uncertain tax positions as of September 30, 2016 (unaudited) or December 31, 2015.

Concentration of Credit Risk

The cash and cash equivalents held in the Company's business money market and other bank accounts are with local and national banking institutions and subjected to FDIC insurance limits of $250,000 per banking institution. As of September 30, 2016, the Company's balances in these bank accounts exceeded the insured amount by $19,187,000.

Recent Accounting Pronouncements

There are no recently issued accounting pronouncements that the Company has yet to adopt that are expected to have a material effect on its financial position, results of operations, or cash flows.

NOTE 2 - SHARE BASED PAYMENT

The Company has outstanding stock options issued to employees and board members which are exercisable at $0.23 per share. The options vest 20% each year over a five year period and expire after ten years. As of September 30, 2016, there were no unvested options. There was no stock option expense recognized for the nine months ended September 30, 2016 or 2015 in the accompanying condensed consolidated statements of income.

A summary of stock option activity as of September 30, 2016, and changes during the period then ended is presented below.

6

On August 11, 2016, the Company granted an aggregate of 450,000 shares of restricted stock to its directors and a consultant. Pursuant to the stock award agreement, the grant of restricted stock of the Company vests in full on August 11, 2017 (the "Vesting Date"), subject to the recipient's continued service with the Company; provided, however, to the extent the recipient's service with the Company is terminated for any reason within thirty (30) days prior to or upon a Change in Control (as defined in the Agreement) prior to the Vesting Date, this grant of restricted stock will immediately and automatically vest in full. The Company recorded stock based compensation of approximately $9,000 related to this grant during the three and nine months ended September 30, 2016. Total unrecognized expense related to the restricted stock grant amounted to approximately $54,000, which will be recognized through the Vesting Date.

NOTE 3 - STOCKHOLDERS' EQUITY

Our authorized capital consists of 750,000,000 shares of common stock and 50,000,000 shares of preferred stock. Our preferred stock may be designated into series pursuant to authority granted by our Certificate of Incorporation, and on approval from our Board of Directors. As of September 30, 2016 and December 31, 2015, we did not have any preferred stock issued.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The discussion and analysis of our financial condition and results of operations are based on our financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

As used in this "Management's Discussion and Analysis of Financial Condition and Results of Operation," except where the context otherwise requires, the term "we," "us," "our," the "Company," or "Tiger X" refers to the business of Tiger X Medical, Inc.

The following discussion should be read together with the information contained in the unaudited condensed consolidated financial statements and related notes included in Item 1, "Financial Statements," in this Form 10-Q.

Overview

Tiger X Medical, Inc. ("Tiger X" or the "Company"), formerly known as Cardo Medical, Inc., previously operated as an orthopedic medical device company specializing in designing, developing and marketing high performance reconstructive joint devices and spinal surgical devices. During 2010, the Company discontinued its orthopedic medical device operations and sold the assets from its previous business lines during 2011. Through July 1, 2016, our continuing operations included the collection and management of our royalty income earned in connection with the Asset Purchase Agreement with Arthrex. 

On August 22, 2016, the Company, Icicle Acquisition Corp., a Delaware corporation and a direct wholly-owned subsidiary of the Company ("Merger Sub"), and BioCardia, Inc., a Delaware corporation ("BioCardia"), entered into an Agreement and Plan of Merger (the "Merger Agreement"), pursuant to which Merger Sub will merge with and into BioCardia, with BioCardia continuing as the surviving company under the name "BioCardia, Inc." (the "Merger"). The Company expects the Merger to close in October 2016.

Critical Accounting Policies

Use of Estimates

Financial statements prepared in accordance with United States generally accepted accounting principles ("U.S. GAAP") require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Among other things, management makes estimates relating to share-based payments, and deferred income tax assets. Given the short operating history of Tiger X, actual results could differ from those estimates.

Royalty Agreement

On January 24, 2011, the Company entered into an Asset Purchase Agreement with Arthrex (the "Arthrex Asset Purchase Agreement"), pursuant to which the Company agreed to sell the assets of its arthroplasty division, referred to as the Reconstructive Division, to Arthrex. The Arthrex Asset Purchase Agreement also provided for the Company to receive royalty payments equal to 5% of net sales of the Company's products made by Arthrex on a quarterly basis for a term up to and including the 20th anniversary of the June 10, 2011 closing date. These amounts were reflected as royalty income on the accompanying condensed consolidated statements of income.

On May 5, 2016, the Company entered into a Royalty Settlement and Release Agreement (the "Royalty Settlement and Release Agreement") with Arthrex, whereby Arthrex agreed to pay the Company $5,642,302 (the "Royalty Payment") in full satisfaction of all amounts due or payable, or which could become payable under the Arthrex Asset Purchase Agreement. Of the Royalty Payment, $142,302 of the amount represented royalty income due to the Company under the Arthrex Asset Purchase Agreement through the date of the Royalty Settlement and Release Agreement, and the remaining $5,500,000 represented the settlement of future royalties. The Royalty Settlement and Release Agreement became effective on July 1, 2016 upon the receipt of the Royalty Payment.

Revenue Recognition

The Company's revenue consists of royalty income from Arthrex pursuant to the Arthrex Asset Purchase Agreement. Revenue is recognized as the amount becomes known and collectability is reasonably assured.

Recent Accounting Pronouncements

There are no recently issued accounting pronouncements that we have yet to adopt that are expected to have a material effect on our financial position, results of operations, or cash flows.

Results of Operations for the Three Months Ended September 30, 2016 as Compared to the Three Months Ended September 30, 2015.

The following is a comparison of the condensed consolidated results of operations for Tiger X for the three months ended September 30, 2016 and 2015.

Royalty income

Royalty income amounted to $5,500,000 for the quarter ended September 30, 2016 as compared to $121,000 for the quarter ended September 30, 2015. Revenues represented royalties received from Arthrex in connection with the Arthrex Asset Purchase Agreement. We entered into a Royalty Settlement and Release Agreement with Arthrex on May 5, 2016 and effective on July 1, 2016, whereby we agreed to receive approximately $5,642,000 (including approximately $142,000 of royalty income recorded during the three months ended June 30, 2016) in full satisfaction of all amounts due or payable, or which become payable under the Arthrex Asset Purchase Agreement. The remaining $5,500,000 was recorded as revenue upon the closing of the agreement on July 1, 2016. Other than this amount recorded on July 1, 2016 under the terms of the Royalty Settlement and Release Agreement, we will have no further royalty income.

General and Administrative Expenses

General and administrative expenses for the quarter ended September 30, 2016 increased by $341,000 as compared to the same period in 2015 due primarily to increased legal and professional expenses during the quarter ended September 30, 2016 associated with the Royalty Settlement and Release Agreement with Arthrex, along with the Merger Agreement with BioCardia.

9

Results of Operations for the Nine Months Ended September 30, 2016 as Compared to the Nine Months Ended September 30, 2015.

The following is a comparison of the condensed consolidated results of operations for Tiger X for the nine months ended September 30, 2016 and 2015.

Royalty income

Royalty income amounted to $5,791,000 for the nine months ended September 30, 2016 as compared to $382,000 for the nine months ended September 30, 2015. Revenues represented royalties received from Arthrex in connection with the Arthrex Asset Purchase Agreement. We entered into a Royalty Settlement and Release Agreement with Arthrex on May 5, 2016 and effective on July 1, 2016, whereby we agreed to receive approximately $5,642,000 in full satisfaction of all amounts due or payable, or which become payable under the Arthrex Asset Purchase Agreement. Other than this amount recorded on July 1, 2016 under the terms of the Royalty Settlement and Release Agreement, we will have no further royalty income.

General and Administrative Expenses

General and administrative expenses for the nine months ended September 30, 2016 increased by $363,000 as compared to the same period in 2015 due primarily to increased legal and professional expenses associated with the Royalty Settlement and Release Agreement with Arthrex, along with the Merger Agreement with BioCardia.

Liquidity and Capital Resources

Net cash provided by operating activities was $5,597,000 for the nine months ended September 30, 2016 compared to net cash provided by operating activities of $217,000 for the same period in 2015. The change between the nine months ended September 30, 2016 and the same period in 2015 was primarily due to an increase in royalty income in 2016.

We had no cash flows from investing or financing activities during the nine months ended September 30, 2016 or 2015.

We believe our cash and cash equivalents as of September 30, 2016 are adequate to meet our cash needs for the next twelve months and beyond.
