Note 1 - Business Organization and Basis of Presentation

CohBar, Inc. (“CohBar” or the “Company”) is a leader in the research and development of mitochondria-based therapeutics (MBTs), an emerging class of drugs for the treatment of diseases associated with aging. MBTs originate from the discovery by the Company’s founders of a novel group of peptides within the genome of mitochondria, the powerhouses of the cell. The Company’s ongoing development of these mitochondrial-derived peptides (MDPs) into MBTs offers the potential to address a broad range of diseases such as type 2 diabetes, cancer, atherosclerosis and neurodegenerative disorders.

The Company’s primary activities since inception include research and development of its MBT pipeline, securing intellectual property protection, managing collaborations with Contract Research Organizations (“CROs”) and academic institutions, expanding its scientific leadership and laboratory staff and raising capital. To date, the Company has not generated any revenues from operations and does not expect to generate any revenues in the near future.

The unaudited interim condensed financial statements of the Company have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (“SEC”). They do not include all information and footnotes required by GAAP for complete financial statements. Except as disclosed herein, there have been no material changes in the information disclosed in the notes to the financial statements for the year ended December 31, 2015, included in the Company’s Annual Report on Form 10-K (the “2015 Form 10-K”), filed with the SEC on March 30, 2016. The interim unaudited condensed financial statements should be read in conjunction with those audited financial statements included in the 2015 Form 10-K. In the opinion of management, all adjustments considered necessary for fair presentation, consisting solely of normal recurring adjustments, have been made. Operating results for the three and six month periods ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016, or any other period.

Note 2 - Management’s Liquidity Plans

As of June 30, 2016, the Company had working capital and stockholders’ equity of $8,478,041 and $8,612,480, respectively. During the six months ended June 30, 2016, the Company incurred a net loss of $2,744,122. The Company has not generated any revenues, has incurred net losses since inception and does not expect to generate revenues in the near term.

With the $9,052,771 in cash and investments on hand as of June 30, 2016, the Company believes that it has sufficient capital to meet its operating expenses and working capital needs into the third quarter of 2017, at which time additional capital will be required. However, if unanticipated difficulties arise the Company may be required to raise additional capital to support its operations or curtail its research and development activities until such time as additional capital becomes available. There is no assurance that additional financing will be available when needed or that the Company will be able to obtain such financing on reasonable terms. The Company does not expect to generate revenues from its operations in the near future and there is no assurance that the Company will generate positive operating cash flow or become profitable in the future. If the Company is unable to raise sufficient additional funds, it will have to develop and implement a plan to reduce overhead or scale back its business plan until sufficient additional capital is raised to support further operations. There can be no assurance that such a plan will be successful.

Note 3 - Summary of Significant Accounting Policies

Basis of Presentation

All amounts are presented in U.S. Dollars.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at dates of the financial statements and the reported amounts of revenue and expenses during the periods. Actual results could differ from these estimates. The Company’s significant estimates and assumptions include the fair value of financial instruments, stock-based compensation, debt discount and the valuation allowance relating to the Company’s deferred tax assets.

Investments

Investments consist of U.S. Treasury Bills of $1,929,640, which are classified as held-to-maturity, and Certificates of Deposit of $1,493,097. The Company determines the appropriate balance sheet classification of its investments at the time of purchase and evaluates the classification at each balance sheet date. All of the Company’s U.S. Treasury Bills mature within the next twelve months. Unrealized gains and losses are de minimis. As of June 30, 2016, the carrying value of the Company’s U.S. Treasury Bills approximates their fair value.

Fair Value of Financial Instruments

The Company measures the fair value of financial assets and liabilities based on 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 Company utilizes three levels of inputs that may be used to measure fair value:

Level 1 - quoted prices in active markets for identical assets or liabilities

Level 2 - quoted prices for similar assets and liabilities in active markets or inputs that are observable

Level 3 - inputs that are unobservable (for example, cash flow modeling inputs based on assumptions)

The carrying amounts of cash, marketable securities, accounts payable, accrued liabilities and short-term debt approximate fair value due to the short-term nature of these instruments. The amount of long-term debt included in the accompanying condensed balance sheets approximates its fair value.

Share-Based Payment

The Company accounts for share-based payments using the fair value method. For employees and directors, the fair value of the award is measured, as discussed below, on the grant date. For non-employees, fair value is generally valued based on the fair value of the services provided or the fair value of the equity instruments on the measurement date, whichever is more readily determinable and re-measured on each financial reporting dates until the service is complete. The Company has granted stock options at exercise prices equal to the higher of (i) the closing price of the Company’s common stock as reported on the OTCQX marketplace or (ii) the closing price of the Company’s common stock as reported by the TSX Venture Exchange on the date of grant.

Note 3 - Summary of Significant Accounting Policies (continued)

The weighted-average fair value of options and warrants has been estimated on the date of grant using the Black-Scholes option-pricing model. The fair value of each instrument is estimated on the date of grant utilizing certain assumptions for a risk free interest rate, volatility and expected remaining lives of the awards. Since the Company has a limited history of being publicly traded, the fair value of stock-based payment awards issued was estimated using a volatility derived from an index of comparable entities. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, the Company’s stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. In estimating the Company’s forfeiture rate, the Company analyzed its historical forfeiture rate, the remaining lives of unvested options, and the number of vested options as a percentage of total options outstanding. If the Company’s actual forfeiture rate is materially different from its estimate, or if the Company reevaluates the forfeiture rate in the future, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.

The weighted-average Black-Scholes assumptions are as follows:

As of June 30, 2016, total unrecognized stock option compensation expense is $2,063,482, which will be recognized as those options vest over a period of approximately four years. The amount of future stock option compensation expense could be affected by any future option grants or by any option holders leaving the Company before their grants are fully vested. 

Net Loss Per Share of Common Stock

Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period.  Diluted net earnings per share reflects the potential dilution that could occur if securities or other instruments to issue common stock were exercised or converted into common stock.  Potentially dilutive securities are excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive and consist of the following:

Note 5 - Commitments and Contingencies

Litigations, Claims and Assessments

The Company may from time to time be party to litigation and subject to claims incident to the ordinary course of business. As the Company grows and gains prominence in the marketplace it may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of these matters could materially affect the Company’s future results of operations, cash flows or financial position. The Company is not currently a party to any legal proceedings.

Operating Lease

The Company is a party to a lease agreement for a laboratory facility. The laboratory space is leased on a month-to-month basis and is part of a shared facility in Menlo Park, California.

Rent expense was $40,640 and $26,727 for the three months ended June 30, 2016 and 2015, respectively. Rent expense was $75,035 and $45,742 for the six months ended June 30, 2016 and 2015, respectively. Rent expense for the six months ended June 30, 2015 included $5,700 for a previous laboratory space in Pasadena, California.

Note 6 - Stockholders’ Equity

Stock Options

The Company has one incentive stock plan, the Amended and Restated 2011 Equity Incentive Plan (the “2011 Plan”), and has granted stock options to employees, non-employee directors and consultants from the 2011 Plan. Options granted under the 2011 Plan may be Incentive Stock Options or Non-statutory Stock Options, as determined by the Administrator at the time of grant. In January 2016, the Company issued a warrant to purchase 125,000 shares of the Company’s common stock to an investor relations firm as partial compensation for consulting services it will provide to the Company over a two year period. Pursuant to applicable policies of the TSX-V, the shares issuable under the warrant will be counted against the limit of shares authorized for issuance under the 2011 Plan, notwithstanding that the warrant was not issued under the 2011 Plan. After giving effect to this limitation there are 1,665,572 shares remaining available for issuance under the 2011 Plan at June 30, 2016.

Note 6 - Stockholders’ Equity (continued)

During the six months ended June 30, 2016, the Company granted stock options to employees to purchase 1,696,000 shares of the Company’s common stock. The stock options have exercise prices that range from $1.10 to $1.55 per share, are subject to vesting over four years, have terms of ten years and have an aggregate grant date fair value of approximately $1,418,000.

During the six months ended June 30, 2016, 10,000 stock options were exercised for cash proceeds of $2,600.

The Company recorded $209,655 and $70,691 of stock based compensation in the three months ended June 30, 2016 and 2015, respectively. The Company recorded $333,301 and $216,205 of stock-based compensation in the six months ended June 30, 2016 and 2015, respectively.

The following table represents stock option activity for the six months ended June 30, 2016:

The table above includes (i) 260,218 options granted to agents that took part in the IPO in the outstanding and exercisable balances at June 30, 2016 and (ii) 470,930 options exercised by agents that took part in the IPO in exercised balance. All other balances are for employees and consultants.

Agent’s Compensation Options

In connection with the closing of its Initial Public Offering (“IPO”) in January 2015 the Company issued 786,696 compensation options (“Compensation Options”) to the agents that took part in the offering. Each Compensation Option was exercisable for a unit consisting of one share of common stock and one-half of one common stock purchase warrant at an exercise price of $1.00 per unit. The Compensation Options expired on July 6, 2016. Each whole warrant issuable upon exercise of Compensation Options is exercisable to acquire one share of common stock at an exercise price of $2.00 per share at any time up to January 6, 2017, subject to the Company’s right to accelerate the expiration time of the warrants if at any time the volume-weighted average trading price of its common stock is equal to or exceeds $3.00 per share for twenty (20) consecutive trading days. Because the Compensation Options are considered a cost of the IPO, the resulting value is recognized as both an increase and decrease to the equity section of the accompanying condensed balance sheets.

During the six months ended June 30, 2016, the agents that took part in the Company’s IPO exercised a total of 470,930 Compensation Options into shares of common stock for cash proceeds of $470,930. An additional 25,431 Compensation Options were exercised during the six months ended June 30, 2016 for cash proceeds of $25,431. The common shares were subsequently issued in July 2016. The proceeds from the 25,431 Compensation Option exercise are included in Additional Paid-in Capital in the accompanying condensed balance sheet. As of June 30, 2016, 234,787 Compensation Options were outstanding.

Overview

We are a leader in the research and development of mitochondria-based therapeutics (MBTs), an emerging class of drugs with potential for the treatment of diseases associated with aging. MBTs originate from the discovery by our founders of a novel group of peptides within the genome of mitochondria, the powerhouses of the cell. Our ongoing development of these mitochondrial-derived peptides (MDPs) into MBTs offers the potential to address a broad range of diseases such as type 2 diabetes, cancer, atherosclerosis and neurodegenerative disorders.

Our operations to date have been focused on organizing and staffing our company, business planning, raising capital and research on our MDPs. Our research efforts have focused on discovering and evaluating our MDPs for potential development as MBT drug candidates. We seek to identify and advance research on MDPs with superior potential for yielding a MBT drug candidate, and ultimately a drug, for which we have a strong intellectual property position.

Since our formation in 2007, we have in-licensed key intellectual property from our founders’ affiliated academic institutions, developed methods for identifying new MDPs, studied various MDPs in both in vitro and in vivo models and identified a number of MDPs with potential therapeutic value in the treatment of diabetes, cancer, Alzheimer’s disease, atherosclerosis and other diseases. Based on our evaluation of MDPs currently in our research pipeline we are actively engaged in research of four MDPs for potential advancement into MBT drug candidate programs.

We are the exclusive licensee from the Regents of the University of California and the Albert Einstein College of Medicine of four issued U.S. patents, three U.S. patent applications and several related international patent applications in various international jurisdictions. Our licensed patents and patent applications include claims that are directed to compositions comprising MDPs and their analogs and/or methods of their use in the treatment of indicated diseases.

We have financed our operations primarily through proceeds from sales of our equity securities and, to a lesser extent, from grants from research foundations. Since our inception through June 30, 2016, our operations have been funded with an aggregate of approximately $20.8 million, of which approximately $0.2 million was from a grant-funding organization and approximately $20.6 million was from the issuance of equity instruments.

Since inception, we have incurred significant operating losses. Our net losses were $2,744,122 and $1,648,795 for the six months ended June 30, 2016 and 2015, respectively. As of June 30, 2016, we had an accumulated deficit of $11,078,659. Our net losses may fluctuate significantly from quarter to quarter and from year to year. We expect to continue to incur significant expenses and operating losses as we continue research, discovery and pre-clinical development efforts on our current MBT candidates and any other MDPs, expand and protect our intellectual property portfolio, and hire additional development and scientific personnel. Our MBT drug target candidates are in early stages of investigational research. Candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect research and development costs to increase significantly for the foreseeable future as our product candidate development programs progress.

Financial Operations Review

Revenue

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the near future. In the future, we will seek to generate revenue from product sales, either directly or under any future licensing, development or similar relationship with a strategic partner.

Research and development expenses

Research and development expenses consist primarily of costs incurred for our research activities, including our drug discovery efforts, and the development of our product candidates, which include:

We expense all research and development expenses as incurred. We expect our research and development expenses to continue to increase for the remainder of the year ending December 31, 2016, as we continue our efforts related to discovering, evaluating and optimizing our MDPs as potential MBT drug candidates.

General and administrative expenses

General and administrative expenses consist primarily of salaries and other related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. Other significant costs include legal fees relating to patent and corporate matters and fees for accounting and consulting services. We anticipate that our general and administrative expenses will increase in the future to support continued research and development activities and the potential commercialization of our product candidates. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, lawyers and accountants, among other expenses. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with exchange listing and Securities and Exchange Commission requirements, insurance and investor relations costs.

Results of Operations

The following tables set forth our results of operations for the periods presented. The period-to-period comparison of financial results is not necessarily indicative of financial results to be achieved in future periods.

Comparison of Three Months Ended June 30, 2016 and 2015

Research and development expenses were $852,596 in the three months ended June 30, 2016 compared to $447,287 in the prior year period, a $405,309 increase. The increase in research and development expenses was due primarily to an increase of approximately $296,000 in salary, benefits and stock-based compensation due to the expansion of our scientific staff and an increase of approximately $107,000 in laboratory supplies related to our efforts to develop optimized MBT candidates. We expect research and development expenses to increase in the coming quarters as we continue to develop optimized MBT candidates.

General and administrative expenses were $674,569 in the three months ended June 30, 2016 compared to $418,932 in the prior year period, a $255,637 increase. The increase in general and administrative expenses was primarily due to an increase in salary, benefits and stock-based compensation due to the expansion of our general and administrative staff with the addition of our new Chief Executive Officer and the timing of a bonus accrued in the current year quarter. We expect general and administrative expenses for the year ending December 31, 2016 to be higher in comparison to prior years as we incur costs associated with the addition of our new CEO and we continue to incur costs associated with running a public company.

Comparison of Six Months Ended June 30, 2016 and 2015

Research and development expenses were $1,589,696 in the six months ended June 30, 2016 compared to $710,047 in the prior year period, an $879,649 increase. The increase in research and development expenses was due primarily to an increase of approximately $533,000 in salary, benefits and stock-based compensation due to the expansion of our scientific staff, an increase of approximately $277,000 in laboratory supplies and preclinical study costs related to our efforts to develop optimized MBT candidates.  We expect research and development expenses to increase in the coming quarters as we continue to develop optimized MBT candidates.

General and administrative expenses were $1,154,501 in the six months ended June 30, 2016 compared to $935,918 in the prior year period, a $218,583 increase. The increase in general and administrative expenses was primarily due to an increase in salary, benefits and stock-based compensation due to the expansion of our general and administrative staff with the addition of our new Chief Executive Officer and the timing of a bonus accrued in the current year period. We expect general and administrative expenses for the year ending December 31, 2016 to be higher in comparison to prior years as we incur the costs associated with the addition of our new CEO and we continue to incur the costs associated with running a public company. 

Liquidity and Capital Resources

As of June 30, 2016 we had $5,630,034 in cash and cash equivalents. We maintain our cash in a checking and savings account on deposit with a banking institution in the United States. We also maintain a portfolio of short-term highly liquid securities investing in U.S. Treasury Bills and Certificate of Deposits. As of June 30, 2016, we had an investments balance of $3,422,737.

Cash Flows from Operating Activities

Net cash used in operating activities for the six months ended June 30, 2016 and 2015 was $2,407,424 and $1,799,394, respectively. The cash used in operations for the six months ended June 30, 2016 was primarily due to our reported net loss of $2,744,122 offset by $333,301 in stock based compensation expense in the current year period. The cash used in operations of $1,799,394 for the six months ended June 30, 2015 was primarily due to our reported net loss of $1,648,795.

Cash Flows from Investing Activities

Net cash provided by investing activities in the six months ended June 30, 2016 was $2,022,549. The cash provided by investing activities of $2,022,549 was primarily due to the timing of maturities of our investments when compared to the purchases of those investments. The cash used in investing activities of $4,975,005 in the six months ended June 30, 2015 was primarily due to net purchases of U.S. Treasury Bills and Certificates of Deposit totaling $4,745,714 and purchases of property and equipment totaling $212,679 as we built out our lab during the six month period ended June 30, 2015.

Cash Flows from Financing Activities

Net cash provided by financing activities in the six months ended June 30, 2016 and 2015 was $1,211,222 and $12,973,221, respectively. Cash provided by financing activities of $1,211,222 in the six months ended June 30, 2016 was primarily due to the exercise of Compensation Options resulting in proceeds of $496,376 and the exercise of common stock purchase warrants resulting in proceeds of $712,246. Cash provided by financing activities of $12,973,221 in the six months ended June 30, 2015 was primarily due to the completion of our IPO. We sold 11,250,000 units in the IPO at a price of $1.00 per unit, providing net proceeds of $10,253,484, net of agents’ commissions and expenses. Concurrently with the IPO, we also completed a previously-subscribed private placement of an additional 2,700,000 units for gross proceeds of $2,700,000.

Item 4.    Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, we conducted an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934, as amended (“Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded as of the end of the period covered by this report that our disclosure controls and procedures were not effective due to a material weakness. The material weakness relates to our having one employee assigned to positions that involve processing financial information, resulting in a lack of segregation of duties so that all journal entries and account reconciliations are reviewed by someone other than the preparer, heightening the risk of error or fraud. If we are unable to remediate the material weakness, or other control deficiencies are identified, we may not be able to report our financial results accurately, prevent fraud or file our periodic reports as a public company in a timely manner. Due to our small size and the early stage of our business, segregation of duties may not always be possible and may not be economically feasible. We have limited capital resources and have given priority in the use of those resources to our research and development efforts. As a result, we have not been able to take steps to improve our internal controls over financial reporting during the quarter ended June 30, 2016. However, we continue to evaluate the effectiveness of internal controls and procedures on an on-going basis. As our operations grow and become more complex, we intend to hire additional personnel in financial reporting and other areas. However, there can be no assurance of when, if ever, we will be able to remediate the identified material weaknesses.

Changes in Internal Control over Financial Reporting

There were no changes in 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, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.    Legal Proceedings

We may from time to time be party to litigation and subject to claims incident to the ordinary course of business. As we grow and gain prominence in the marketplace we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of these matters could materially affect our future results of operations, cash flows or financial position. We are not currently a party to any legal proceedings.
