Moleculin Biotech, Inc.
Notes to the Consolidated Financial Statements
(Unaudited)
 
1. Nature of Business and Liquidity
 
The terms “MBI” or the “Company”, “we”, “our” and “us” are used herein to refer to Moleculin Biotech, Inc. MBI is a clinical stage pharmaceutical company organized as a Delaware corporation in July 2015 to focus on the development of anti-cancer drug candidates, all of which are based on license agreements with The University of Texas System on behalf of the M.D. Anderson Cancer Center, which the Company refers to as MD Anderson. MBI has three core drug technologies: a uniquely designed anthracycline (Annamycin), a portfolio of STAT3 inhibitors (WP1066 Portfolio) and a collection of inhibitors of glycolysis (WP1122 Portfolio). The Company's clinical stage drugs are Annamycin, an anthracycline designed to avoid multidrug resistance mechanisms with little to no cardiotoxicity being studied for the treatment of relapsed or refractory acute myeloid leukemia, more commonly referred to as AML, and WP1066, an immuno-stimulating STAT3 inhibitor targeting primary brain tumors and brain metastases, pancreatic cancer and hematological malignancies. MBI is also engaged in preclinical development of additional drug candidates, including additional STAT3 inhibitors and compounds targeting the metabolism of tumors.

In June 2018, MBI formed Moleculin Australia Pty. Ltd., (MAPL), a wholly-owned subsidiary, to begin preclinical development in Australia for WP1732, an analog of WP1066. This may enable the Company to enjoy the benefits of certain research and development tax credits in Australia.

The Company currently has six drug candidates representing three substantially different approaches to treating cancer. Liposomal Annamycin, which MBI refers to as Annamycin, is a chemotherapy designed to inhibit the replication of DNA of rapidly dividing cells. WP1122 and its analog, WP1234 are inhibitors of glycolysis intended to cut off the fuel supply of tumor cells, which are often overly dependent on glycolysis as compared to healthy cells. And, finally, the Company believes that WP1066, WP1732, and its analog, WP1220, have shown capability, in in vivo testing, of altering the cell signaling associated with tumors. The Company has two drugs in three clinical trials.

The Company's most mature drug candidate is Annamycin, an anthracycline being studied for the treatment of relapsed or refractory AML. Annamycin had been in clinical trials pursuant to an investigational new drug application or IND that had been filed with the U.S. Food and Drug Administration, or FDA. Due to a lack of development activity by a prior drug developer, this IND was terminated. To permit the renewed investigation of Annamycin, the Company submitted a new IND for a Phase I/II trial for the treatment of relapsed or refractory AML in August 2017, which the FDA allowed to go into effect in September 2017. The trial in the US is open and is actively recruiting.

The Company has five other drug development projects:

• WP1066 has an approved physician-sponsored clinical trial open for enrollment for the treatment of brain tumors and is also being evaluated for potential treatment of AML and pancreatic cancer,
• WP1220, an analog of WP1066 is being studied for the topical treatment of cutaneous T-cell lymphoma (CTCL) and MBI expects to file a Clinical Trial Application ("CTA") prior to year-end,
• WP1732, another analog of WP1066, that it believes is particularly well suited for intravenous administration, is being evaluated for potential treatment of AML, pancreatic and other cancers, and MBI has begun pre-clinical work which we expect to generate sufficient data for an IND by year-end, and
• WP1122 and WP1234 are being evaluated for their potential to treat brain tumors and pancreatic cancer via their ability to inhibit glycolysis.

The Company has been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all of MBI's drug technologies, as these intellectual property rights are owned in part or entirely by MD Anderson. The Annamycin drug substance is no longer covered by any existing patent protection, however, the Company intends to submit patent applications for formulation, synthetic process and reconstitution related to MBI's Annamycin drug product candidate, although there is no assurance that the Company will be successful in obtaining such patent protection. Independently from potential patent protection, MBI has received Orphan Drug designation from the FDA for Annamycin for the treatment of AML, which may provide tax and other benefits during product development and if the product is approved for AML, may lead to a grant of seven-year market exclusivity. Under that exclusivity, which runs from the date of the approval of the New Drug Application (NDA) in the United States, the FDA generally (there are important exceptions) could not approve another Annamycin product for AML. The Company also intends to apply for similar status in the European Union (EU) where market
7


exclusivity extends to 10 years from the date of Marketing Authorization Application (MAA) approval. Separately, the FDA may also grant market exclusivity of 5 years for newly approved new chemical entities (which the Company believes Annamycin would be one), but there can be no assurance that such exclusivity will be granted.

With regard to additional potential clinical activity, the Company received Polish National Office approval in June 2018 for a Clinical Trial Authorization ("CTA") in Poland, which enables the Company to begin a Phase I/II clinical trial there to study Annamycin for the treatment of relapsed or refractory AML. The Company has one site in Poland open for the trial. This will be in addition to the previously announced allowance of MBI's IND in the United States. The start of clinical trials in Poland is expected to begin in the second half of 2018. In the US, the Company has three sites recruiting patients and ready to provide treatments. Patient treatment began in the US in March of this year. In addition, the Company continues to recruit and contract with clinics both in the United States and Poland. The Company can provide no assurance of additional recruitment or that treatments will occur in the near term and on a timely basis, if at all.

  In July 2018, the physician-sponsored WP1066 trial IND for the treatment of glioblastoma opened for recruitment. 

On May 1, 2018, the Company engaged another contract research organization ("CRO") to evaluate additional countries for the expansion of our AML clinical trial, specifically Australia and several Western European countries to provide additional clinical sites to improve access for patients to MBI's Phase I/II trial. This evaluation is ongoing.

In September 2017, the Company engaged a CRO to prepare for a proof-of-concept clinical trial in Poland to study its drug candidate WP1220, a part of the WP1066 portfolio, for the treatment of CTCL. The Company filed a CTA in Poland for this use, which if approved, will give the Company its third drug in a clinical trial.

  In accordance with FASB ASC Topic 280, Segment Reporting, the Company views its operations and manage its business as principally one segment. As a result, the financial information disclosed herein represents all the material financial information related to its principal operating segment.

Prior to MBI's initial public offering, the Company acquired Moleculin, LLC which was merged with and into MBI. Moleculin, LLC was the holder of a license agreement with MD Anderson covering technology referred to as the WP1066 Portfolio, which is focused on the modulation of key oncogenic transcription factors.

2. Basis of presentation, principles of consolidation and significant accounting policies
 
Basis of Presentation – Unaudited Interim Consolidated Financial Information - The accompanying unaudited interim consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for financial information, and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) with respect to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim financial statements furnished reflect all adjustments (consisting of normal recurring adjustments), which are, in the opinion of management, necessary for a fair statement of results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited financial statements of the Company as of December 31, 2017 and December 31, 2016 and notes thereto contained in the Form 10-K filed with the SEC on March 28, 2018.

Principles of consolidation - The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. As of June 30, 2018, there is only one subsidiary company. All intercompany balances and transactions have been eliminated in consolidation. Any reference in these notes to applicable guidance is meant to refer to GAAP. The Company views its operations and manages its business in one operating segment. All material long-lived assets of the Company reside in the United States.
 
Use of Estimates - The preparation of these financial statements in conformity with U.S. GAAP requires 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 expenses during the reporting period. Actual results could differ from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including: expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation of financial statements. Estimates are used in the following areas, among others: fair value estimates on intangible assets, warrants, and stock-based compensation expense, accrued expenses and taxes. 

Going Concern - These consolidated financial statements have been prepared on a going concern basis, which assumes the Company will continue to realize its assets and discharge its liabilities in the normal course of business. The continuation of the Company as a going concern is dependent upon the ability of the Company to obtain necessary equity financing to continue operations and the attainment of profitable operations. As of June 30, 2018, the Company has incurred an accumulated deficit of $21.5 million since inception and had not yet generated any revenue from operations. Additionally, management anticipates that its cash on hand as of June 30, 2018 is sufficient to fund its planned operations into but not beyond the near term. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations, strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. Management cannot be certain that such events or a combination thereof can be achieved.
 
Cash and Cash Equivalents - The Company considers all highly liquid accounts with original maturities of three months or less at the date of acquisition to be cash equivalents. Periodically in the ordinary course of business, the Company may carry cash balances at financial institutions in excess of the insured limits of $250,000. The amount in excess of the applicable insurance coverage at June 30, 2018 was not material.

Intangible assets - Intangible assets with finite lives are amortized using the straight-line method over their estimated period of benefit. If an intangible asset is identified as an in-process research & development ("IPR&D") asset, then no amortization will occur until the development is complete. If the associated research and development effort is abandoned, the related assets will be written-off and the Company will record a noncash impairment loss on its statements of operations. For those compounds that reach commercialization, if any, the IPR&D assets will be amortized over their estimated useful lives.

9


The Company evaluates the recoverability of intangible assets periodically and takes into account events or circumstances that warrant revised estimates of useful lives or that indicate that impairment exists. No material impairments of intangible assets have been identified during any of the periods presented. Intangible assets are tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach.

Fair Value of Financial Instruments - The Company's financial instruments consist primarily of account payables, accrued expenses and a warrant liability. The carrying amount of accounts payables and accrued expenses approximates their fair value because of the short-term maturity of such.
 
The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into a three-level fair value hierarchy in accordance with GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).
 
Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:
 
Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.
Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or  liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument.
Level 3 – Unobservable inputs for the asset or liability.
 
The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of its warrant liability discussed in Note 4.  In the accompanying consolidated financial statements as of June 30, 2018, the fair value of this warrant liability is included in current liabilities for the 2017 Issuance of Warrants and in long-term liabilities for the February 2018 Issuance of Warrants and the June 2018 Issuance of Warrants. The latter is due to the warrants issued during 2018 having an exercise price substantially higher than the current market value of the Company’s stock; therefore, management considers it a long-term liability.
 
The following table provides the financial assets and liabilities reported at fair value and measured on a recurring basis at December 31, 2017 and June 30, 2018 (in thousands):

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is determined using the weighted-average number of common shares outstanding during the period, adjusted for the dilutive effect of common stock equivalents. In periods when losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive. For the three months and six months ended June 30, 2018, the Company’s potentially dilutive shares, which were not included in the calculation of net loss per share, included options to purchase 2,754,000 common shares and warrants to purchase 3,784,515 common shares as inclusion of these securities would have been anti-dilutive. For the three months and six months ended June 30, 2017, the Company's potentially dilutive shares, which were not included in the calculation of net loss per share, included options to purchase 530,000 common shares and warrants to purchase 948,011 common shares as inclusion of these securities would have been anti-dilutive.
 
Reclassifications – A reclassification was made to the prior period financial statements to conform to the 2018 presentation. Such reclassification did not affect net loss as previously reported. Historically, "accrued expenses and current liabilities" were included in the line item "accounts payable and accrued expenses". Management believes that these costs are best shown as separate line items and, as such, a reclassification was made to the Statement of Cash Flows for the six months ended June 30, 2017 by reducing “Accounts payable" and now creating a new line item “Accrued expenses and other liabilities”.

Subsequent Events - The Company’s management reviewed all material events through the date these consolidated financial statements were issued for subsequent events disclosure consideration and has noted events in notes to the unaudited consolidated financial statements.
 
Recent Accounting Pronouncements  
 
In May 2014, the FASB issued Accounting Standard Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and
11


provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In August 2015, the FASB approved a proposal to defer the effective date of the guidance until annual and interim reporting periods beginning after December 15, 2017. The Company is currently evaluating the impact that this standard will have on its consolidated financial statements at the time the Company starts to generate revenue or enters into other contractual arrangements, which the Company does not expect in the near term.
 
In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements.
 
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is currently evaluating the impact that this standard will have on its financial statements.
 
In August 2016, the FASB issued ASU, Statement of Cash Flows (Topic 230). This ASU applies to all entities that are required to present a statement of cash flows under Topic 230. The amendments provide guidance on eight specific cash flow issues and includes clarification on how these items should be classified in the statement of cash flows and is designed to help eliminate diversity in practice as to where items are classified in the cash flow statement. Furthermore, in November 2016, the FASB issued additional guidance on this Topic that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with earlier application permitted for all entities. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements.
 
In January 2017, the FASB issued ASU 2017-01 "Business Combinations (Topic 805)," which provides a screen to determine when an integrated set of assets and activities is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments in this update also narrow the definition of the term "output" so that the term is consistent with how outputs are described in Topic 606. Public business entities are required to apply the amendments in this update to annual periods beginning after December 15, 2017, including interim periods within those periods. Early application is permitted. The Company will evaluate the effect of the update at the time of any future acquisition or disposal.
 
In May 2017, the FASB issued ASU 2017-09 "Compensation—Stock Compensation (Topic 718)." This update clarifies the existing definition of the term "modification," which is currently defined as "a change in any of the terms or conditions of a share-based payment award." The update requires entities to account for modifications of share-based payment awards unless the (1) fair value, (2) vesting conditions and (3) classification as an equity instrument or a liability instrument of the modified award are the same as of the original award before modification. Public business entities are required to adopt the amendments in this update for fiscal years and interim periods beginning after December 15, 2017, with early adoption permitted. The adoption of this pronouncement did not have a material impact on the Company's consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718) Improvements to Non-employee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 affects all entities that enter into share-based payment transactions for acquiring goods and services from non-employees. The amendments in this Update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from non-employees. The
12


amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption permitted, but no earlier than an entity's adoption date of Topic 606. The Company is currently evaluating the impact that this standard will have on its financial statements. 

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements ("ASU 2018-09"). ASU 2018-09 affects a wide variety of topics in the Codification and applies to all reporting entities within the scope of the affected accounting guidance. The amendments in this Update are effective based on the facts and circumstances of each amendment. Some of the amendments do not require transition guidance and will be effective upon issuance of this Update. However, many of the amendments do have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. The Company is currently evaluating the impact that this standard will have, if any, on its financial statements.

The Company does not believe that any other recently issued effective pronouncements, or pronouncements issued but not yet effective, if adopted, would have a material effect on the accompanying consolidated financial statements.

Total accrued expenses and other liabilities$1,839 $902 


4. Warrant Liability
 
The basis of value of the warrant liability is fair value, which is defined pursuant to Accounting Standards Codification (“ASC”) 820 to be “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date”. The Company used the Black-Scholes option pricing model (“BSM”) to determine the fair value of the Series A and Series B Warrants from the February 2017 Issuance, described below, along with the warrants issued in the February 2018 Issuance and June 2018 Issuance. The Company used a Monte Carlo simulation (“MCM”) with regard to the Series C Warrants from the February 2017 Issuance because of the path dependent vesting terms of the contract.

The risk-free interest rate assumption is based upon observed interest rates on zero coupon U.S. Treasury bonds whose maturity period is appropriate for the term of the warrants and is calculated by using the average daily historical stock prices through the day preceding the issuance date.

Estimated volatility is a measure of the amount by which its stock price is expected to fluctuate each year during the expected life of the warrants. Where appropriate, the Company used the historical volatility of peer entities due to the lack of sufficient historical data of its stock price during 2017-2018.

June 2018 Issuances of Warrants

On June 22, 2018, the Company entered into a definitive agreement with institutional investors for a registered direct offering of securities for the sale of 1,092,636 shares of its common stock, at a purchase price of $2.105 per share. Concurrently with the sale of the common shares, pursuant to the agreement, the Company also sold warrants to purchase 710,212 shares of common stock. The total number of warrants issued were 742,991, which includes the Roth Warrants below. The Company sold the common shares and warrants for aggregate gross proceeds of approximately $2.3 million. Subject to certain beneficial ownership limitations, the warrants will be initially exercisable on the six months anniversary of the issuance date at an exercise price equal to $2.02 per share of common stock, subject to adjustments as provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the agreement occurred on June 22, 2018.

The shares of common stock above (but not the warrants or the shares of common stock underlying the warrants) were being offered and sold pursuant to a shelf registration statement (File No. 333-219434) which became effective on August 21, 2017. 
The Company also entered into a placement agent agreement (the “Placement Agency Agreement”) with Roth Capital Partners, LLC (“Roth”), pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the common shares and warrants. The Company paid Roth an aggregate fee equal to 6.5% of the gross proceeds received from the sale of the securities in the transactions. Pursuant to the Placement Agency Agreement, it also issued Roth warrants to purchase up to 3% of the aggregate number of shares of common stock sold in the transactions (the “Roth Warrants”) or 32,779 shares. The Roth Warrants have substantially the same terms as the investor warrants described above, except that the Roth Warrants will expire on June 21, 2023 and have an exercise price of $2.3155 per share. The Roth Warrants and the shares issuable upon exercise of the Roth Warrants will be issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and in reliance on similar exemptions under applicable state laws. The Company also reimbursed Roth for its expenses of $50,000. The Company agreed to give Roth a nine months right of first refusal to act as its lead underwriter or exclusive placement agent for any further capital raising transactions the Company undertakes. With certain exceptions, the Company also granted Roth a six-month tail fee equal to the cash and warrant compensation in the offering, if any investor with which Roth had substantive discussions with respect to the offering, provides MBI with further capital during such six months period following termination of its engagement of Roth.

February 2018 Issuance of Warrants

On February 16, 2018, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors for the sale of 4,290,000 shares of its common stock, at a purchase price of $2.10 per share. Concurrently with the sale of the common shares, pursuant to the Purchase Agreement, the Company also sold warrants to purchase 2,145,000 shares of common stock. The total number of warrants issued were 2,273,700, which includes the Roth Warrants below. The Company sold the common shares and warrants for aggregate gross proceeds of approximately $9.0 million.

14


provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the Purchase Agreement occurred on February 21, 2018. 

The warrants and the shares issuable upon exercise of the warrants were sold without registration under the Securities
Act of 1933 ("Securities Act") in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and Rule 506 promulgated under the Securities Act as sales to accredited investors, and in reliance on similar exemptions under applicable state laws.

The Company also entered into a placement agent agreement (the “Placement Agency Agreement”) with Roth Capital Partners, LLC (“Roth”), pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the common shares and warrants. The Company paid Roth an aggregate fee equal to 6.5% of the gross proceeds received from the sale of the securities in the transactions. Pursuant to the Placement Agency Agreement, it also issued Roth warrants to purchase up to 3% of the aggregate number of shares of common stock sold in the transactions (the “Roth Warrants”) or 128,700 shares. The Roth Warrants have substantially the same terms as the investor warrants described above, except that the Roth Warrants will expire on February 15, 2023. The Roth Warrants and the shares issuable upon exercise of the Roth Warrants will be issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act as transactions not involving a public offering and in reliance on similar exemptions under applicable state laws. The Company also reimbursed Roth for its expenses of $75,000. The Company agreed to give Roth a nine-month right of first refusal to act as its lead underwriter or exclusive placement agent for any further capital raising transactions it undertakes. With certain exceptions, the Company also granted Roth a six-month tail fee equal to the cash and warrant compensation in the offering, if any investor with which Roth had substantive discussions with respect to the offering, provides MBI with further capital during such six-month period following termination of its engagement of Roth.

February 2017 Issuance of Warrants

On February 9, 2017, the Company entered into an Underwriting Agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC, as representative of the several underwriters identified therein (collectively, the “Underwriters”), pursuant to which it sold in a registered public offering (the “Offering”), 3,710,000 units, priced at a public offering price of $1.35 per unit (the closing price that day was $1.50), with each unit consisting of: (i) one share of common stock, (ii) a five-year Series A warrant to purchase 0.50 of a share of common stock, (iii) a 90-day Series B warrant to purchase one share of common stock, and (iv) a five-year Series C warrant to purchase 0.50 of a share of common stock. The Series C warrants in a unit could only be exercised to the extent and in proportion to a holder of the Series C warrants exercising its Series B warrants
15


included in the unit. The Series A and Series C warrant have an exercise price of $1.50 per share of common stock. The Series B warrant had an exercise price of $1.35 per share of common stock.

Under the terms of the Underwriting Agreement, the Company granted the Underwriters a 45-day option to purchase an additional 556,500 shares of common stock and/or an additional 556,500 warrant combination (comprised of an aggregate of 278,250 Series A warrants, 556,500 Series B warrants and 278,250 Series C warrants), in any combinations thereof, from MBI to cover over-allotments at the public offering price per share of $1.349 and public offering price per warrant combination of $0.001, respectively, less the underwriting discounts and commissions. Upon the closing of the Offering, the Underwriters exercised the over-allotment option with respect to $278,100 warrant combinations. The Company received approximately $4.5 million in net proceeds from the Offering, after deducting underwriting discounts and commissions and estimated offering expenses.

Warrant Activity
 
The Series B Warrants and the unvested Series C Warrants expired in May 2017. Therefore, the associated warrant liability of $1.2 million was extinguished on that date and no other Series B Warrants were exercised.

On June 30, 2018, the warrants were revalued with a fair value determination of $3.7 million which included a fair value adjustment for the three and six months ended of $0.3 million and $1.0 million, respectfully, and was included as a gain in "Gain (loss) from change in fair value of warrant liability" in the accompanying financial statements.

 
5. Equity
 
The Company is authorized to issue 80,000,000 shares of which 5,000,000 shares of preferred stock are authorized and 75,000,000 shares of common stock are authorized.
  
Preferred Stock
 
The Company is authorized to issue up to 5,000,000 shares of preferred stock.

Common Stock

At Market Issuance Sales Agreement (ATM)
 
On September 15, 2017, the Company entered into an At Market Issuance Sales Agreement (the “ATM Agreement”) with Roth Capital Partners, LLC and National Securities Corporation (collectively, the “Agents”). Pursuant to the terms of the ATM Agreement, it may sell from time to time through the Agents shares of the Company’s common stock with an aggregate sales price of up to $13.0 million.
 
Any sales of Shares pursuant to the Agreement will be made under its effective “shelf” registration statement on Form S-3 (File No. 333-219434) which became effective on August 21, 2017 and the related prospectus supplement and the accompanying prospectus, as filed with the SEC on September 15, 2017. Under the ATM Agreement, the Company may sell shares through an Agent by any method that is deemed an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”).
 
Sales of the shares may be made at market prices prevailing at the time of sale, subject to such other terms as may be agreed upon at the time of sale, including a minimum sales price that may be stipulated by MBI's Board of Directors or a duly authorized committee thereof. The Company or the Agents, under certain circumstances and upon notice to the other, may suspend the offering of the Shares under the Agreement.
 
The Company agreed to pay a commission to the Agents of 3.0% of the gross proceeds of the sale of the Shares sold under the Agreement and to reimburse the Agents for certain expenses. The Company has also provided the Agents with customary indemnification rights.

During the six months ended June 30, 2018, the Company did not sell any shares under this Agreement.

In January 2018, the Company granted to a new member of its science advisory board options in the aggregate to purchase 10,000 shares of the Company’s common stock with an exercise price of $1.89 per share, a term of 10 years, and a vesting period of 4 years.

In January 2017, the Company granted members of its science advisory board options in the aggregate to purchase 20,000 shares of the Company’s common stock with an exercise price of $2.31 per share, a term of 10 years, and a vesting period of 4 years. The exercise price was based upon the closing price of the stock on the day of the grant. The options have an aggregated fair value of $35,196 that was calculated using the Black-Scholes option-pricing model. In July and August 2017, the Company granted options to the Board and a management member to purchase 140,000 shares of the Company's common stock with exercise prices of $1.87 and $2.88, respectively, with a term of 10 years and a vesting period of 4 years. The options have an aggregated fair value of $234,395 for the six months ended June 30, 2018, calculated using the Black-Scholes option-pricing model.
 
The fair value of the option grants has been estimated, with the following weighted-average assumptions:

Options granted during 2018 have an aggregated fair value of $1.8 million that was calculated using the Black-Scholes option-pricing model. As of June 30, 2018, total compensation cost not yet recognized was $3.8 million and the weighted average period over which this amount is expected to be recognized is 3.28 years. No options were exercised in 2018. The fair value of each stock option is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions noted in the above paragraph and table. The expected term of the options was computed using the "plain vanilla" method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin 107 because the Company does not have sufficient data regarding employee exercise behavior to estimate the expected term. The volatility was determined by referring to the average historical volatility of a peer group of public companies because the Company does not have sufficient trading history to determine our historical volatility. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

Consulting Agreement 

In 2017, the Company entered into a consulting agreement for its investor relations operations. The consulting agreement initially covered a period of twelve months from the commencement date of July 29, 2017 and was extended in April 2018 until March 31, 2019. Pursuant to the original consulting agreement, in exchange for the consulting services, the Company issued two warrants (collectively, the “Warrants”) to purchase 100,000 and 50,000 shares of common stock at exercise prices of $2.41 and $3.00 per share.

Each of the Warrants vests over a 12-month period in equal monthly installments starting July 29, 2017, provided that the consultant is providing services to the Company pursuant to the consulting agreement on each vesting date. The Warrants became initially exercisable on August 8, 2017 and expire five years from the initial exercise date. The Company recorded stock compensation expense for the non-employee consulting agreement of $35,278 and $71,525 for the three and six months ended June 30, 2018 based on the fair value of the warrants vested as of June 30, 2018. In connection with the extension of the consulting agreement, the Company issued the consultant a three-year warrant to purchase 100,000 shares of common stock at an exercise price of $3.00 per share vesting in four quarterly installments.

$9 million Registered Direct Offering

On February 16, 2018, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain institutional investors for the sale of 4,290,000 shares of MBI's common stock, at a purchase price of $2.10 per share. Concurrently with the sale of the common shares, pursuant to the Purchase Agreement, the Company also sold warrants to purchase 2,145,000 shares of common stock. The Company sold the common shares and warrants for aggregate gross proceeds of approximately $9.0 million. The net proceeds from the transactions was approximately $8.2 million after deducting certain fees due to the placement agent and transaction expenses. Subject to certain beneficial ownership limitations, the warrants will be initially exercisable on the six-month anniversary of the issuance date at an exercise price equal to $2.80 per share of common stock, subject to adjustments as provided under the terms of the warrants. The warrants are exercisable for five years from the initial exercise date. The closing of the sales of these securities under the Purchase Agreement occurred on February 21, 2018.

The Company also entered into a placement agent agreement (the “Placement Agency Agreement”) with Roth Capital Partners, LLC (“Roth”), pursuant to which Roth agreed to serve as exclusive placement agent for the issuance and sale of the common shares and warrants. The Company paid Roth an aggregate fee equal to 6.5% of the gross proceeds received from the sale of the securities in the transactions. Pursuant to the Placement Agency Agreement, it also granted to Roth warrants to purchase up to 3% of the aggregate number of shares of common stock sold in the transactions (the “Roth Warrants”). The Company also reimbursed Roth for its expenses of $75,000. The Company agreed to give Roth a nine-month right of first refusal to act as its lead underwriter or exclusive placement agent for any further capital raising transactions it undertakes. With certain exceptions, the Company also granted Roth a six-month tail fee equal to the cash and warrant compensation in the offering, if any investor with which Roth had substantive discussions with respect to the offering, provides MBI with further capital during such six-month period following termination of our engagement of Roth.

 $2.3 million Registered Direct Offering

On June 22, 2018, the Company entered into a definitive agreement with institutional investors for a registered direct offering of securities with gross proceeds of approximately $2.3 million. In connection with the offering, the Company issued 1,092,636 registered shares of common stock at a purchase price of $2.105 per share. Concurrently in a private placement, for each share of common stock purchased by an investor, such investor received from the Company an unregistered warrant to purchase 0.65 of a share of common stock. The warrants have an exercise price of $2.02 per share, will be exercisable six months from the date of issuance, and will expire five years from the initial exercise date. Roth Capital Partners served as sole placement agent for the offering.  
 
6. Income Taxes
 
Deferred income tax assets and liabilities are determined based upon differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company does not expect to pay any significant federal, state, or foreign income taxes in 2018 as a result of the losses recorded during the three and six months ended June 30, 2018 and the additional losses expected for the remainder of 2018 and cumulative Net Operating Losses. Accounting standards require the consideration of a valuation allowance for deferred tax assets if it is “more likely than not” that some component or all of the benefits of deferred tax assets will not be realized. As a result, as of June 30, 2018, the Company maintained a full valuation allowance for all deferred tax assets.
 
The Company recorded no income tax provision for the six months ended June 30, 2018 and 2017. The effective tax rate for the six months ended June 30, 2018 and 2017 was 0%. The income tax rates vary from the federal and state statutory rates primarily due to the valuation allowances on the Company’s deferred tax assets. The Company estimates its annual effective tax rate at the end of each quarterly period. Jurisdictions with a projected loss for the year where no tax benefit can be recognized due to the valuation exclusion could result in a higher or lower effective tax rate during a particular quarter depending on the mix and timing of actual earnings versus annual projections.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a federal corporate tax rate decrease from 35% to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax
19


system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. As of December 31, 2017, the Company estimated our provision for income taxes in accordance with the Tax Act and guidance available as of the date of the fourth quarter 2017 filing. The amount related to the remeasurement of deferred tax assets and liabilities, based on the rates at which they are expected to reverse in the future, was an expense of $1.6 million. Since the Company maintains a full valuation allowance against its deferred tax assets, there was no net impact to the Company's earnings on this remeasurement of its gross deferred tax assets. As of the date of the fourth quarter 2017 filing, we asserted that the effects of this remeasurement were a provisional amount in accordance with the guidance of Staff Accounting Bulletin No. 118 ("SAB 118"). As of the June 30, 2018, the Company has determined that no changes are expected to the provisional amount recorded in the fourth quarter of 2017. As such, the Company considers the accounting to be complete as of the first quarter of 2018 for the remeasurement of deferred tax asset and liabilities in accordance with the Tax Act.
 
7. Commitments and Contingencies

The term of the Lease began in August 2018 for an initial term of 66 months, which may be renewed for an additional 5 years. The Company is required to remit base monthly rent of approximately $4,300 which will increase at an average approximate rate of 3.00% each year. The Company is also required to pay additional rent in the form of our pro-rata share of certain specified operating expenses of the Landlord. The newly leased space is located in Houston, Texas. The corporate office lease will be classified as an operating lease.
