Catalyst Biosciences, Inc. (the “Company” or “Catalyst”), is a clinical-stage biotechnology company focused on developing novel medicines to address hematology indications, including the treatment of hemophilia. Its facilities are in South San Francisco, California and it operates in one segment.

Prior to August 20, 2015, the name of the Company was Targacept, Inc. (“Targacept”). On August 20, 2015, Targacept completed its business combination with Catalyst Bio, Inc. (“Catalyst Bio”) by and among Targacept, Talos Merger Sub, Inc. (“Merger Sub”) and Catalyst Bio, pursuant to which Merger Sub merged with and into Catalyst Bio, with Catalyst Bio surviving as a wholly-owned subsidiary of Targacept (the “Merger”) and changed its name from Targacept, Inc. to Catalyst Biosciences, Inc. Prior to and in connection with the Merger, the Company paid a dividend to the Targacept holders consisting of cash and non-interest bearing redeemable convertible notes (the “Pre-Closing Dividend”), see Note 5 for further detail.  

On February 10, 2017, the Company effected a reverse stock split of its common stock at a ratio of 1-for-15 (“2017 Reverse Stock Split”). The 2017 Reverse Stock Split was approved by the Company’s stockholders at a special meeting of stockholders held on February 2, 2017. As a result of the 2017 Reverse Stock Split, each 15 pre-split shares of common stock outstanding were automatically combined into one new share of common stock, and the number of outstanding shares of common stock on the date of the split was reduced from approximately 13.0 million shares to approximately 868,000 shares. Unless otherwise specified, all share and per share amounts in these notes and the accompanying consolidated financial statements are reported on a post-stock split basis for all periods presented.

On April 3, 2017, under the Company’s at the market offering program with JonesTrading Institutional Services LLC (“JonesTrading”), the Company sold an aggregate of 241,600 shares of its common stock for approximately $3.5 million of net proceeds. Following such sales, the Company has no more common stock available for sale under the program.

On April 12, 2017, the Company issued and sold in a registered, underwritten public offering an aggregate of (i) 1,470,000 shares of common stock (including 540,000 shares of common stock sold pursuant to the exercise of the Underwriter’s overallotment option), (ii) 13,350 shares of Series A Preferred Stock, each convertible into 200 shares of common stock and (iii) warrants to purchase 2,070,000 shares of common stock at an exercise price of $5.50 per share (including 270,000 sold pursuant to the exercise of the underwriter’s overallotment option). The net proceeds to the Company, after deducting the underwriting discounts and commissions and offering expenses payable by the Company was approximately $18.7 million.

Basis of Presentation

The Company’s condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and following the requirements of the SEC for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for a fair presentation of the Company’s financial information. These interim results and cash flows for any interim period are not necessarily indicative of the results to be expected for the full year.

The accompanying condensed consolidated financial statements and related financial information should be read in conjunction with the consolidated financial statements filed with the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“Annual Report”).

The Company’s significant accounting policies are included in “Part II - Item 8 - Financial Statements and Supplementary Data - Note 2 – Summary of Significant Accounting Policies” in the Company’s Annual Report. There have been no significant changes to these accounting policies during the first three months of 2017.

Notes to Condensed Consolidated Financial Statements (Unaudited) - (Continued)

For a description of the fair value hierarchy and the Company’s fair value methodology, see “Part II - Item 8 - Financial Statements and Supplementary Data - Note 2 – Summary of Significant Accounting Policies” in the Company’s Annual Report. There were no significant changes in these methodologies during the three months ended March 31, 2017. As of March 31, 2017, the Company’s highly liquid money market funds included cash equivalents and restricted cash, including deposit in an escrow account and as of December 31, 2016, included cash equivalents, U.S. government agency securities and restricted cash, including deposit in an escrow account, these financial assets are valued using Level 1 inputs. There were no transfers in or out of Level 1 and Level 2 during the periods presented.

Liabilities that are measured at fair value consist of the derivative liability and is valued using Level 3 inputs. There were no transfers in or out of Level 3 during the periods presented.

As of March 31, 2017 and December 31, 2016 the fair value of the derivative liability was immaterial. The estimated reporting date fair value-based measurement of the derivative liability was calculated using the Black-Scholes valuation model.

The following tables present the fair value hierarchy for assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016 (in thousands):

Cash equivalents, restricted cash and short-term investments, all of which are classified as available-for-sale securities, consisted of the following (in thousands):

There have been no significant realized gains or losses on available-for-sale securities for the periods presented. The carrying amounts of cash, accounts receivable and accounts payable approximate fair values due to the short-term maturity of these instruments.

On August 19, 2015, immediately prior to the Merger, the Company issued to Targacept stockholders non-interest bearing redeemable convertible notes (the “Notes”) in the aggregate principal amount of $37.0 million. The Notes do not bear interest. The principal amount of the Notes are convertible, at the option of each noteholder, into cash or into shares of the Company’s common stock at a conversion rate of $137.85 per share, and are payable in cash, if not previously redeemed or converted, at maturity on February 19, 2018, the 30-month anniversary of the closing of the issuance of the Notes.

In connection with the Pre-Closing Dividend, on August 19, 2015, Targacept entered into an indenture (the “Indenture”) with American Stock Transfer & Trust Company, LLC, as trustee, and an escrow agreement with American Stock Transfer & Trust Company, LLC and Delaware Trust Company, LLC, as escrow agent, under which $37.0 million, which represented the initial principal amount of the convertible notes, was deposited in a segregated escrow account for the benefit of the holders of the notes in order to facilitate the payment of the notes upon redemption or at maturity (the amount of such deposit together with interest accrued and capitalized thereon, the “Escrow Funds”). The Notes are the Company’s secured obligation, and the Indenture does not limit its other indebtedness, secured or unsecured.

Holders of the Notes may submit conversion notices, which are irrevocable, instructing the trustee to convert such Notes into shares of common stock at a conversion price of $137.85 per share. Following each conversion date, the Company will issue the number of whole shares of common stock issuable upon conversion as promptly as practicable (and in any event within 10 business days). The trustee will in turn release to the Company the respective amount of restricted cash to cover the stock issuance.

The conversion to common stock feature of the Notes was determined to be a derivative liability requiring bifurcation and separate accounting. The fair value of such conversion feature at issuance was determined to be $1.5 million. The bifurcation of the derivative liability from the estimated fair value of the Notes of $37.1 million at issuance resulted in a debt discount of $1.4 million. The Company elected to accrete the entire debt discount as interest expense immediately after the Merger. In addition, changes in the fair value of the derivative liability are being recorded within interest and other income in the consolidated statements of operations. The Company remeasures the derivative liability to fair value until the earlier of the conversion, redemption or maturity of the redeemable convertible notes.

As of March 31, 2017 and December 31, 2016, the fair value of the derivative liability was immaterial. The estimated reporting date fair value-based measurement of the derivative liability was calculated using the Black-Scholes valuation model.

The Company recognized no interest expense for both the three months ended March 31, 2017 and 2016, related to the amortization of the debt discount within interest expense on the Company’s consolidated statement of operations as the redeemable convertible notes are immediately fully redeemable at the option of the holders.

As of March 31, 2017, $24.1 million of the Notes were redeemed and $0.3 million of the Notes were converted into common stock. $6.7 million of the Notes were redeemed during the three months ended March 31, 2017. The Company recognized no gain on the extinguishment of Notes upon the redemption of the Notes during the three months ended March 31, 2017.

The following table summarizes stock option activity under the Company’s equity incentive plans, including stock options granted to non-employees, and related information:

Valuation Assumptions

The Company estimated the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. This fair value is being amortized ratably over the requisite service periods of the awards, which is generally the vesting period. The fair value of employee stock options was estimated using the following weighted-average assumptions for the three months ended March 31, 2016:

Total stock-based compensation recognized was as follows (in thousands):

As of March 31, 2017, 101,304 shares of common stock were available for future grant, 44,704 options to purchase shares of common stock were outstanding and the Company had unrecognized employee stock-based compensation expense of $1.0 million, related to unvested stock awards, which is expected to be recognized over an estimated weighted-average period of 2.36 years.

Pfizer

On August 20, 2013, the Company and Pfizer signed an amendment to the Factor VIIa collaboration agreement in which the companies agreed to provide specific mutual releases and covenants and modify certain milestone payment schedules in the agreement.

On April 2, 2015, Pfizer notified the Company that it was exercising its right to terminate the research and license agreement effective June 1, 2015. The termination became effective 60 days after the Company’s receipt of the termination notice. On June 1, 2015, the license and certain rights under the research and license agreement terminated and reverted to the Company.

On December 8, 2016, the Company signed an agreement with Pfizer pursuant to which the parties terminated the research and license agreement that was signed on June 29, 2009. Pursuant to the new agreement, Pfizer granted the Company an exclusive license to Pfizer’s proprietary rights for manufacturing and processes that apply to Factor VIIa variants, CB 813a (marzeptacog alfa (activated)). Pfizer has also transferred and will transfer to the Company documentation related to the development, manufacturing and testing of the Products, including the Investigational New Drug (“IND”) application as well as the orphan drug designation.

As part of the new agreement, the Company agreed to make contingent cash payments to Pfizer in an aggregate amount equal to up to $17.5 million, payable upon the achievement of clinical, regulatory and commercial milestones. Following commercialization of any covered product, Pfizer would also receive a single-digit royalty on net product sales on a country-by-country basis for a predefined royalty term. No amounts have been paid to date under this new agreement.

ISU Abxis

On June 16, 2013, the Company signed a license and collaboration agreement with ISU Abxis, whereby the Company licensed its proprietary human Factor IX products to ISU Abxis for initial development in South Korea. Under the terms of the agreement, ISU Abxis is responsible for manufacturing, preclinical development activities and clinical development through completion of a proof-of-concept Phase 1/2 study in individuals with hemophilia B. The Company has the sole rights and responsibility for worldwide development, manufacture, and commercialization of Factor IX products after Phase 1/2 development. ISU Abxis may exercise its right of first refusal to acquire commercialization rights in South Korea, in which case they would be entitled to profit sharing on worldwide sales. ISU’s rights will also terminate if the Company enters into a license agreement with another party to develop, manufacture and commercialize Factor IX products in at least two major market territories.

ISU Abxis paid the Company an up-front signing fee of $1.75 million and is obligated to pay to the Company contingent milestone-based payments on the occurrence of certain defined development events, and reimbursement for a portion of the Company’s costs relating to intellectual property filings and maintenance thereof on products. The Company is obligated to pay ISU Abxis a percentage of all net profits it receives from collaboration products.

Contract revenue of $0.3 million and $0.1 million for the three months ended March 31, 2017 and 2016, respectively, reflected (i) the amortization of the up-front fee over the estimated period of the Company’s performance obligations under the agreement, which was assessed to be four years beginning in September 2013 when the agreement was executed and (ii) $0.2 million recorded in March 2017 for a milestone payment earned by the Company. The deferred revenue balance related to the ISU Abxis collaboration was $0.3 million and $0.6 million as of March 31, 2017 and 2016, respectively.

The following table sets forth the computation of the basic and diluted net loss per share during the three months ended March 31, 2017 and 2016 (in thousands, except share and per share data):

Catalyst Biosciences, Inc.

Notes to Condensed Consolidated Financial Statements (Unaudited) - (Continued)

Since the Company was in a loss position for all periods presented, diluted net loss per share is the same as basic net loss per share for all periods as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities on an as-if converted basis that were not included in the diluted per share calculations because they would be anti-dilutive were as follows:

On March 16, 2016, the Company signed a Capital on Demand^TM Sales Agreement with JonesTrading. In accordance with the terms of the sales agreement, the Company may offer and sell shares of its common stock having an aggregate offering price up to $6.5 million, subject to certain limitations, from time to time in one or more public offerings of the Company’s common stock, with JonesTrading acting as agent, in transactions pursuant to a shelf registration statement that was declared effective by the SEC on April 28, 2016.

The Company sold 198,280 shares of common stock in the open market at a weighted-average selling price of $9.55 per share, for net proceeds (net of commissions) of $1.8 million during the three months ended March 31, 2017, in the Capital on Demand^TM program. The Company charged approximately $0.1 million for JonesTrading commission against additional paid-in capital for the three months ended March 31, 2017.    

Operating Leases

The Company leases office space for its corporate headquarters in South San Francisco, California. The lease will expire in February 2018.

Future minimum lease payments under all non-cancelable operating leases as of March 31, 2017, were as follows (in thousands):

Manufacturing Agreements

On May 20, 2016, the Company entered into a development and manufacturing services agreement with CMC ICOS Biologics, Inc. (“CMC”), pursuant to which CMC will conduct manufacturing development and, upon successful development of the manufacturing process, manufacture the Company’s next-generation Factor VIIa variant marzeptacog alfa (activated) that the Company intends to use in its clinical trials. The Company has agreed to a total of $3.8 million in payments to CMC pursuant to the initial statement of work under the Agreement, subject to completion of applicable work stages. As of March 31, 2017, the Company was obligated to $2.1 million in payments to CMC remaining under the agreement.

11.     Interest and Other Income

As of March 31, 2017 and December 31, 2016, the fair value of the derivative liability was immaterial.

The following table shows the detail of other income/(expense), net for the three month periods ended March 31, 2017 and 2016 (in thousands):

12.     Subsequent events

On April 3, 2017, under the Company’s at the market offering program with JonesTrading, the Company sold an aggregate of 241,600 shares of its common stock for approximately $3.5 million of net proceeds. Following such sales, the Company has no more common stock available for sale under the program.

On April 12, 2017, the Company issued and sold in a registered, underwritten public offering an aggregate of (i) 1,470,000 shares of common stock (including 540,000 shares of common stock sold pursuant to the exercise of the Underwriter’s overallotment option), (ii) 13,350 shares of Series A Preferred Stock, each convertible into 200 shares of common stock and (iii) warrants to purchase 2,070,000 shares of common stock at an exercise price of $5.50 per share (including 270,000 sold pursuant to the exercise of the Underwriter’s overallotment option). The net proceeds to the Company, after deducting the underwriting discounts and commissions and offering expenses payable by the Company was approximately $18.7 million.

In connection with and following the Company’s underwritten public offering, certain holders of Series A Preferred Stock and warrants elected to convert or exercise such shares and warrants, respectively. In addition, subsequent to March 31, 2017, additional redeemable convertible notes were redeemed by the holders thereof.  Accordingly, as of May 4, 2017, the Company had outstanding 4,260,561 shares of common stock, 5,750 shares of Series A Preferred Stock (convertible into an aggregate of 1,150,000 shares of common stock), warrants to purchase 2,041,075 shares of common stock at an exercise price of $5.50 per share, and options under the Company’s 2015 Stock Incentive Plan to purchase an aggregate of 44,670 shares of common stock at a weighted-average exercise price of $58.65 per share (in addition to other warrants to purchase an aggregate of 12,039 shares of common stock at a weighted-average exercise price of $145.11 per share, other options to purchase an aggregate of 80,619 shares of common stock at a weighted-average exercise price of $154.01 per share and $11.0 million of redeemable convertible promissory notes convertible at a rate of $137.85 per share).

Overview

We are a clinical-stage biopharmaceutical company focused on developing novel medicines to address serious medical conditions for individuals who need new or better treatment options. We used a scientific approach to engineer several protease-based therapeutic candidates. We are focusing our product development efforts in the field of hemostasis (the process that regulates bleeding) and have a mission to develop valuable therapies for individuals with hemophilia.

We are applying our substantial expertise in protease engineering and our proprietary product discovery platform to create, engineer and characterize protease drug candidates. Proteases regulate several complex biological cascades, or sequenced biochemical reactions, including the coagulation cascade (a mechanism of blood clotting) in hemophilia and non-hemophilia settings and the complement cascade that causes inflammation and tissue damage in certain diseases. Our protease expertise allowed us to improve the biochemical and pharmacological properties of currently marketed hemophilia protease drugs, specifically Factors VIIa, IX and Xa and to create completely novel proteases that cleave disease-causing proteins, specifically complement Factor 3 (C3), for the potential treatment of dry age-related macular degeneration (Dry AMD) and renal delayed graft function (DGF).

Our most advanced program is a highly potent next-generation coagulation Factor VIIa protease variant, marzeptacog alfa (activated) (formerly CB 813d), that has successfully completed an intravenous Phase 1 clinical trial evaluating the pharmacokinetics, pharmacodynamics and coagulation activity in individuals with severe hemophilia A and B with and without an inhibitor. We expect to advance marzeptacog alfa (activated) into the Phase 2 portion of a Phase 2/3 subcutaneous prophylaxis efficacy trial in 2017.

Our next most advanced hemophilia program, a highly potent Factor IX protease variant, CB 2679d/ISU304, is IND approved in South Korea. We expect to initiate a Phase 1/2 subcutaneous dosing trial for CB 2679d/ISU304 in the second quarter of 2017.

The substantially enhanced potency of marzeptacog alfa (activated) and CB 2679d/ISU304 compared with existing treatment options may allow for effective subcutaneous prophylactic treatment of individuals with hemophilia A or B with an inhibitor or individuals with hemophilia B, respectively. Catalyst’s engineered hemostasis proteases are designed to overcome current treatment limitations by allowing delivery via subcutaneous injection which we believe will facilitate effective prophylactic treatment, especially in children, and ultimately deliver substantially better outcomes for individuals with hemophilia.

Subcutaneous dosing results in progressive increases in the levels of our protease factors until they reach a stable blood level therapeutic target range (ideally mild hemophilia to normal). Conversely, dosing by intravenous infusions results in very high factor

15

levels in the blood initially, but the factor level then falls rapidly to a trough level at a range that is measured as moderate or severe hemophilia, triggering the next dose.

Stable factor levels could potentially yield a significant improvement in outcomes and have the added benefit of convenience over competing intravenous therapeutics, particularly when administered to children where venous access is challenging.

We also have several Factor Xa variants that have demonstrated efficacy in several preclinical models and have the potential to be used as a universal procoagulant. We have delayed initiating further work on our Factor Xa therapeutic program at this time to focus our efforts on the Factor VIIa and Factor IX clinical programs.

We continue to explore licensing opportunities for our anti-complement programs in DGF and Dry AMD so that we can focus our efforts and resources on advancing marzeptacog alfa (activated) and CB 2679d/ISU304 through Phase 2/3 and Phase 1/2 clinical trials, respectively.

We estimate the total market for our product candidates is $3.4 billion. Based on industry reports, annual worldwide sales in 2016 for Factor VIIa recombinant products for individuals with hemophilia A or B with an inhibitor were approximately $1.4 billion, and prothrombin complex concentrate products used to treat individuals with hemophilia A or B with an inhibitor were $0.8 billion. Worldwide sales in 2016 for Factor IX products for individuals with hemophilia B were approximately $1.2 billion.

On June 29, 2009 we entered into a Research and License agreement with Wyeth Pharmaceuticals, Inc., subsequently acquired by Pfizer, whereby we and Pfizer collaborated on the development of novel human Factor VIIa products and we granted Pfizer the exclusive rights to develop and commercialize the licensed products on a worldwide basis. On April 2, 2015, Pfizer notified us that it was exercising its right to terminate the research and license agreement effective June 1, 2015. Accordingly, we revised the expected period of performance to end on June 1, 2015, and the deferred revenue balance was fully amortized as of that date. On December 8, 2016, we signed a definitive agreement related to the termination of the Pfizer Agreement. Pursuant to this termination agreement, Pfizer granted us an exclusive license to Pfizer’s proprietary rights for manufacturing materials and processes that apply to Factor VIIa variants, CB 813a and marzeptacog alfa (activated). Pfizer also transferred to us the IND application and documentation related to the development, manufacturing and testing of the Factor VIIa products as well as the orphan drug designation.

Pursuant to this agreement, we agreed to make contingent cash payments to Pfizer in an aggregate amount equal to up to $17.5 million, payable upon the achievement of clinical, regulatory and commercial milestones. Following commercialization of any covered product, Pfizer would also receive a single-digit royalty on net product sales on a country-by-country basis for a predefined royalty term.

In September 2013, we signed a license and collaboration agreement with ISU Abxis pursuant to which we licensed our proprietary human Factor IX products to ISU Abxis for initial development in South Korea. Under the agreement, ISU Abxis is responsible for manufacturing, preclinical development activities and clinical development through a proof-of-concept Phase 1/2 study in individuals with hemophilia B. We have the sole rights and responsibility for worldwide development, manufacture, and commercialization of Factor IX products after Phase 1/2 development. ISU Abxis may exercise its right of first refusal to acquire commercialization rights in South Korea, in which case they would be entitled to profit sharing on worldwide sales. ISU Abxis paid us an up-front fee of $1.75 million and is obligated to pay to us contingent milestone-based payments on the occurrence of certain defined development events, of which one has been achieved as of March 31, 2017. Collaboration and license revenue related to the ISU Abxis agreement during the three months ended March 31, 2017 and 2016 was $0.3 million and $0.1 million, respectively, that reflect the amortization of the up-front fee over the estimated period of our performance obligations, which are estimated to conclude in February 2018 and $0.2 million recorded in March 2017 for a milestone earned by us. We had a deferred revenue balance of $0.3 million as of March 31, 2017 related to the ISU Abxis collaboration.

We have never been profitable and have incurred significant operating losses in each year since inception. Our net losses were $4.1 million and $3.6 million for the three months ended March 31, 2017 and 2016, respectively. As of March 31, 2017, we had an accumulated deficit of $152.1 million. Substantially all our operating losses resulted from expenses incurred in our research and development programs and from general and administrative costs associated with our operations.

We expect to incur significant expenses and increasing operating losses for at least the next several years as we continue the preclinical, manufacturing and clinical development, and seek regulatory approval for our drug candidates and our expenses associated with operating as a public company. In addition, our operating losses may fluctuate significantly from quarter to quarter and year to year due to timing of preclinical, clinical development programs and regulatory approval.

Financial Operations Overview

Contract Revenue

Our contract revenue was generated by recognizing revenue from the amortization of up-front licensee fees for research and development services under our collaboration agreements with ISU Abxis. Payments made to us under these agreements are recognized over the period of performance for each arrangement. We may also be entitled to receive additional milestone payments and other contingent payments upon the occurrence of specific events. We have not generated any revenue from commercial product sales to date. ISU Abxis represents 100% of our total contract revenue for the three months ending March 31, 2017 and 2016.

Due to the nature of the milestone payments under the remaining collaboration agreement and the nonlinearity of the earnings process associated with certain payments and milestones, we expect that our revenue will fluctuate in future periods, as a result of the uncertainty of timing related to achievement of milestones.

Research and Development Expenses

Research and development expenses represent costs incurred to conduct research, such as the discovery and development of our product candidates. We recognize all research and development costs as they are incurred.

Research and development expenses consist primarily of the following:

The following table summarizes our research and development expenses during the three months ended March 31, 2017 and 2016 (in thousands):

The largest component of our total operating expenses has historically been our investment in research and development activities, including the clinical development of our product candidates. We are currently focusing substantially all our resources and development efforts on our clinical pipeline. Our internal resources, employees and infrastructure are not directly tied to individual product candidates or development programs. As such, we do not maintain information regarding these costs incurred for these research and development programs on a project-specific basis.

On September 3, 2016, our Board of Directors approved reducing our workforce by 10 employees, or approximately 50% of our workforce consistent with a revised strategic plan to reallocate our resources to our hemostasis programs, including our highly potent next-generation Factor VIIa variant marzeptacog alfa (activated), and our highly potent next-generation Factor IX CB 2679d/ISU304. This reduction in force was completed by the fourth quarter 2016 and we recorded restructuring charges of $1.0 million, for the year ended December 31, 2016. In connection with the restructuring, we received proceeds of $0.9 million for property and equipment from the sale of excess equipment and other assets, which are recorded in other income for the year ended December 31, 2016, there was no further expense recorded during the three months ended March 31, 2017.

Notwithstanding the reduction in force, we expect our aggregate research and development expenses will increase during the next few quarters as we continue the preclinical, manufacturing and clinical development of our product candidates in the United States, particularly the clinical development costs of marzeptacog alfa (activated) and CB 2679d/ISU304. Due to the termination of the

17

research and license agreement with Pfizer, we will incur all costs for the marzeptacog alfa (activated) program. However, the incurrence of such costs is dependent on whether we will pursue the program on our own or sign a new collaboration and license arrangement with another pharmaceutical or biotech company.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in achieving marketing approval for our product candidates. The probability of success of each product candidate may be affected by numerous factors, including clinical data, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration of and costs to complete our research and development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.

Successful development of current and future product candidates is highly uncertain. Completion dates and costs for our research programs can vary significantly for each current and future product candidate and are difficult to predict. Thus, we cannot estimate with any degree of certainty the costs we will incur in the development of our product candidates. We anticipate we will make determinations as to which programs and product candidates to pursue and how much funding to direct to each program and product candidate on an ongoing basis in response to the scientific success of early research programs, results of ongoing and future clinical trials, our ability to enter into collaborative agreements with respect to programs or potential product candidates, as well as ongoing assessments as to each current or future product candidate’s commercial potential.

On May 20, 2016, we signed a development and manufacturing services agreement with CMC ICOS Biologics, Inc. (“CMC”), pursuant to which CMC will conduct manufacturing development and, upon successful development of the manufacturing process, manufacture marzeptacog alfa (activated) that we intend to use in its clinical trials. We will own all intellectual property developed in such manufacturing development activities that are specifically related to marzeptacog alfa (activated) and will have a royalty-free and perpetual license to use CMC’s intellectual property to the extent reasonably necessary to make marzeptacog alfa (activated), including commercial manufacturing.

We have agreed to a total of $3.8 million in payments to CMC pursuant to the initial statement of work under the Agreement, subject to completion of applicable work stages. In the event that clinical manufacturing batches need to be cancelled or rescheduled, we would be obligated to pay for a portion of CMC’s manufacturing fees less certain fees that CMC is able to mitigate. The initial term of the agreement is ten years or, if later, until all stages under outstanding statements of work have been completed. Either party may terminate the agreement in its entirety upon written notice of a material uncured breach or upon the other party’s bankruptcy, and we may terminate the agreement upon prior notice for any reason. In addition, each party may terminate the agreement in the event that the manufacturing development activities cannot be completed for technical or scientific reasons. As of March 31, 2017, we have $2.1 million in payment obligations to CMC remaining under the agreement.

General and Administrative Expenses

General and administrative expenses consist of personnel costs, allocated expenses and other expenses for outside professional services, including legal, human resources, audit and accounting services. Personnel costs consist of salaries, bonus, benefits and stock-based compensation. We incur expenses associated with operating as a public company, including expenses related to compliance with the rules and regulations of the SEC and NASDAQ Stock Market LLC (“NASDAQ”), additional insurance expenses, additional audit expenses, investor relations activities, Sarbanes-Oxley compliance expenses and other administrative expenses and professional services. We expect such expenses to continue.

Interest and Other Income, Net

Interest and other income consists primarily of the changes in fair value of the derivative liability. The derivative liability is associated with the redeemable convertible notes we issued immediately prior to the closing of the merger in August 2015. The accounting for the redeemable convertible notes, which are convertible into shares of our common stock, requires us to bifurcate the derivative liability and account for it as a derivative liability at its estimated fair value upon issuance. The derivative liability is remeasured to estimated fair value as of each balance sheet date. We will record adjustments to the fair value of the derivative liability at the end of each reporting period until the earlier of the conversion, redemption or maturity of the redeemable convertible notes. As of March 31, 2017 and December 31, 2016, the fair value of the derivative liability was immaterial.

Results of Operations

The following tables set forth our results of operations data for the periods presented (in thousands):

Contract Revenue

Contract revenue was $0.3 million and $0.1 million during the three months ended March 31, 2017 and 2016, an increase of $0.2 million, or 149%. The increase was due to milestone revenue from ISU Abxis of $0.2 million and the recognition of revenue under our collaboration agreement with ISU Abxis.

Research and Development Expenses

Research and development expenses were $2.1 million and $2.3 million during the three months ended March 31, 2017 and 2016, respectively, a decrease of $0.2 million, or 10%. The decrease was due primarily to a decrease of $0.6 million in personnel-related costs in connection with the reduction in workforce and a decrease of $0.7 million in lab supply costs and costs related to preclinical third-party research and development service contracts, partially offset by an increase of $1.1 million related to manufacturing expenses for marzeptacog alfa (activated).

General and Administrative Expenses

General and administrative expenses were $2.4 million during both the three months ended March 31, 2017 and 2016.

Interest and Other Income

Interest and other income was $0.03 million and $1.0 million during the three months ended March 31, 2017 and 2016, respectively, a decrease of $1.0 million, or 97%. The decrease was due primarily to a $1.0 million gain recognized in 2016, related to the change in fair value of the derivative liability in 2016.

Recent Accounting Pronouncements

In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The standard provides guidance on how certain cash receipts and payments are presented and classified in the statement of cash flows, including beneficial interests in securitization. The standard is intended to reduce current diversity in practice. ASU 2016-15 will be effective for the Company beginning in the first quarter of 2018, but early adoption is permitted, including adoption in an interim period. We are currently evaluating the potential impact that this standard may have on our consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new standard involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016. We adopted ASU 2016-09 in the first quarter of 2017 and this guidance did not have a material impact on our financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance for leases. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet

19

for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 will be effective for the Company beginning in the first quarter of 2019, but early adoption is permitted. We are currently evaluating the impact of adopting the new lease standard on our consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Topic 825-10), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 will be effective for the Company beginning in the first quarter of 2018, and early adoption is not permitted. We are currently evaluating the potential impact that this standard may have on our consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards for revenue recognition. ASU 2014-09 is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. Subsequently, the FASB has issued the following standards related to ASU 2014-09: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations; ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. We must adopt ASU 2016-08, ASU 2016-10 and ASU 2016-12 with ASU 2014-09 (collectively, the “new revenue standards”), which will be effective for us beginning in the first quarter of 2018, and early adoption is permitted beginning in the first quarter of 2017. The new revenue standards may be applied retrospectively to each prior period presented or prospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the timing of our adoption and the impact of adopting the new revenue standards on our consolidated financial statements.

Liquidity and Capital Resources

As of March 31, 2017, we had $14.5 million of cash, cash equivalents and short-term investments. We have an accumulated deficit of $152.1 million as of March 31, 2017. Our primary uses of cash are to fund operating expenses, including research and development expenditures and general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in its outstanding accounts payable and accrued expenses.

On March 16, 2016, we entered into a Capital on Demand^TM Sales Agreement with JonesTrading Institutional Services LLC (“JonesTrading”). In accordance with the terms of the sales agreement, we may offer and sell shares of our common stock having an aggregate offering price up to $6.5 million, subject to certain limitations, from time to time in one or more public offerings of our common stock, with JonesTrading acting as agent, in transactions pursuant to a shelf registration statement that was declared effective by the SEC on April 28, 2016. During the three months ended March 31, 2017, we sold 198,280 shares of our common stock in the Capital on Demand^TM program, in the open market at a weighted-average selling price of $9.55 per share, for net proceeds (net of commissions) of $1.8 million.

On April 3, 2017, under our at the market offering program with JonesTrading, we sold an aggregate of 241,600 shares of our common stock for approximately $3.5 million of net proceeds. Following such sales, we had no more common stock available for sale under the Controlled Equity Offering^TM program.

On April 6, 2017, our registration statement on Form S-1 relating to an underwritten public offering of its common and preferred stock was declared effective by the Securities and Exchange Commission (“SEC”).  On April 12, 2017, the Company issued and sold 1,470,000 shares of Common Stock at a price to the public of $5.00 per share (including 540,000 shares of Common Stock sold pursuant to the exercise of the Overallotment Option), 13,350 shares of Series A Preferred Stock, convertible into 2,670,000 shares of common stock, at a price to the public of $1,000.00 per unit and 2,070,000 Warrants at an exercise price of $5.50 per share (which includes 270,000 sold pursuant to the exercise of the Overallotment Option), pursuant to the Registration Statements and the Underwriting Agreement. The net proceeds to the Company, after deducting the underwriting discounts and commissions and estimated offering expenses payable by the Company was approximately $18.7 million.

We believe that our existing capital resources will be sufficient to meet our projected operating requirements for at least the next 12 months. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. We plan to continue to fund losses from operations and capital funding needs through future equity and/or debt financings, as well as potential additional asset sales, licensing transactions, collaborations or strategic partnerships with other companies. The sale of additional equity or convertible debt could result in additional dilution to our stockholders. The incurrence of indebtedness would result in debt service obligations and could result in operating and financing covenants that would restrict our operations. We can provide no assurance that financing will be available in the amounts we need or on terms acceptable to us, if at all. If we are not able to secure adequate additional funding we may be forced to delay, make reductions in spending, extend

20

payment terms with suppliers, liquidate assets where possible, and/or suspend or curtail planned programs. Any of these actions could materially harm our business.

The following table summarizes our cash flows for the periods presented (in thousands):

Cash Flows from Operating Activities

Cash used in operating activities for the three months ended March 31, 2017 was $4.3 million, due primarily to a net loss of $4.1 million, the change in our net operating assets and liabilities of $0.3 million due primarily to a $0.2 million increase in accounts receivable and $0.1 million increase in prepaid expenses, partially offset by non-cash charges of $0.1 million for stock-based compensation.

Cash used in operating activities for the three months ended March 31, 2016 was $4.7 million, due primarily to a net loss of $3.6 million, the change in our net operating assets and liabilities of $0.4 million due primarily to a $0.4 million decrease in accrued compensation and other accrued liabilities, a $0.2 million decrease in accounts payable, $0.1 million decrease in deferred revenue due to the amortization of upfront license fees from our collaborations, partially offset by a $0.3 million decrease in prepaid expenses and other current assets. Also included are non-cash gains of $0.9 million related to change in fair value of the derivative liability and $0.1 million related to extinguishment of redeemable convertible notes, partially offset by non-cash charges of $0.2 million for stock-based compensation and $0.1 million for depreciation and amortization.

Cash Flows from Investing Activities

Cash provided by investing activities for the three months ended March 31, 2017 was $6.8 million, due primarily to $6.8 million in proceeds from maturities of investments.

Cash used in investing activities for the three months ended March 31, 2016 was $3.8 million, due primarily to $3.7 million in purchases of investments and $0.1 million related to the purchase of property and equipment.

Cash flows from Financing Activities

Cash provided by financing activities for the three months ended March 31, 2017 was $1.8 million, due primarily to $1.8 million in net proceeds from issuance of common stock in at-the-market transactions and the release of restricted cash of $6.7 million related to the redemption of some of the redeemable convertible notes which was offset by payments of $6.7 million related to the redemption of some of the redeemable convertible notes.

Cash provided by financing activities for the three months ended March 31, 2016 was $0, due primarily to $2.8 million release of restricted cash related to the redemption of some of the redeemable convertible notes which was offset by payments of $2.8 million related to the redemption of some of the redeemable convertible notes.

21

Contractual Obligations

The following table summarizes our fixed contractual obligations as of March 31, 2017 (in thousands):

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Critical Accounting Polices and Estimates

Certain of our accounting policies that involve a higher degree of judgment and complexity are discussed in “Part II - Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operation - Critical Accounting Estimates” in the Annual Report. There have been no significant changes to these critical accounting estimates during the first three months of 2017.

22

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and interest rates. We are exposed to market risks in the ordinary course of our business. Our primary exposure to market risk is interest income sensitivity in our investment portfolio, although currently income generated from our investment portfolio is insignificant. Fixed rate securities and borrowings may have their fair market value adversely impacted due to fluctuations in interest rates, while floating rate securities may produce less income than expected if interest rates fall and floating rate borrowings may lead to additional interest expense if interest rates increase. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if forced to sell securities that have declined in market value due to changes in interest rates.

However, because of the short-term nature of the instruments in our portfolio, a sudden change in market interest rates would not be expected to have a material impact on the fair market value of our investment portfolio. As of March 31, 2017, we had cash and cash equivalents of $14.5 million, which consisted of bank deposits and money market funds. The redeemable convertible notes we issued in August 2015 in connection with the merger do not bear interest and thus a change in market interest rates would not have an impact on an interest expense related to these redeemable convertible notes. Accordingly, we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates on our investment portfolio.

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2017. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are 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 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 our management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2017, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) identified during the first three months of 2017 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

23

PART II. OTHER INFORMATION

We are not a party to any material legal proceedings.

Other than as described below, we have not identified any material changes to the risk factors previously disclosed in “Part I - Item 1A - Risk Factors” in the Company’s Annual Report. Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to those described below or in the Annual Report, any one or more of which could, directly or indirectly, cause our actual financial condition and operating results to vary materially from past, or from anticipated future, financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, operating results and stock price.

You should carefully consider the risks and uncertainties disclosed as “Risk Factors” in our Annual Report and described below, together with all of the other information in this Report, including the section titled “Part I - Financial Information - Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the condensed consolidated financial statements and related notes.  

We will need additional capital. If we are unable to raise sufficient capital, we will be forced to delay, reduce or eliminate product development programs.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We expect our research and development expenses to increase with our ongoing activities, particularly activities related to the continued clinical development of marzeptacog alfa (activated), including a clinical efficacy trial and, if Phase 1 clinical trials of CB 2679d/ISU304 are successful, an efficacy trial for that compound. We believe that our available cash will be sufficient to fund our operations for at least twelve months. However, we will need to raise substantial additional capital to complete the development and commercialization of marzeptacog alfa (activated), CB 2679d/ISU304, and depending on the availability of capital, may need to delay development of some of our product candidates.

Until we can generate a sufficient revenue from our product candidates, if ever, we expect to finance future cash needs through public or private equity offerings, debt financings, corporate collaborations and/or licensing arrangements. Additional funds may not be available when we need them on terms that are acceptable, or at all. If adequate funds are not available, we may be required to delay, reduce the scope of or eliminate one or more of our research or development programs.

Because successful development of our product candidates is uncertain, we are unable to estimate the actual funds required to complete research and development and commercialize our products under development. Our future funding requirements, both near and long-term, will depend on many factors, including, but not limited to:

24

Raising additional funds by issuing securities or through licensing arrangements may cause dilution to stockholders, restrict our operations or require us to relinquish proprietary rights.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, stockholders will be diluted, and the terms of these new securities may include liquidation or other preferences that adversely affect the rights of common stockholders.

Debt financing, if available at all, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, product candidates or future revenue streams or grant licenses on terms that are not favorable to us. We may also seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. There can be no assurance that we will be able to obtain additional funding if, and when necessary. If we are unable to obtain adequate financing on a timely basis, we could be required to delay, curtail or eliminate one or more, or all, of our development programs or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We depend on our collaborative relationship with ISU Abxis for the Phase 1/2 development of CB 2679d/ISU304.

We have a collaboration agreement with ISU Abxis for preclinical and Phase 1/2 development of an improved, next-generation Factor IX product, CB 2679d/ISU304. Under this agreement, ISU Abxis is responsible for manufacturing and conducting a Phase 1/2 clinical trial for this product candidate, and we depend on ISU Abxis to complete these activities.

Our ability to generate revenues from this arrangement will depend on the ability of ISU Abxis to successfully perform the functions assigned to it in this agreement, and accordingly, any failure by ISU Abxis to develop this product candidate could adversely affect our cash flows. Further, this collaboration agreement may not lead to development or commercialization of this product candidate in the most efficient manner or at all, and ISU Abxis has the right to abandon development projects and terminate applicable agreements, including funding obligations, prior to or upon the expiration of the agreed upon terms. We are subject to a number of risks associated with our dependence on ISU Abxis:
