Notes to Condensed Consolidated Financial Statements
(Unaudited)

Note 1. Description of Business
In these notes to the consolidated financial statements, the “Company,” “we,” “us,’” and “our” refers to Codexis, Inc. and its subsidiaries on a consolidated basis.
We discover, develop and sell proteins that deliver value to our clients in a growing set of industries. We view proteins as a vast untapped source of value-creating materials, and we are using our proven technologies, which we have been continuously improving over our fifteen -year history, to commercialize an increasing number of novel proteins, both as proprietary Codexis products and in partnership with our customers.
Many companies have historically used naturally occurring proteins to produce or enhance goods used in everyday life. Despite the growing number of commercial applications of naturally occurring proteins across many industries, the inherent limitations of naturally-occurring proteins frequently restrict their commercial use. Through the application of our proprietary CodeEvolver ® protein engineering technology platform, we are able to engineer novel proteins to overcome these restrictions, thereby adding value or opening up new prospects for our existing and potential customers’ products, processes or businesses. We have developed new proteins that are significantly more stable and/or active in our customers' commercial applications than proteins derived from nature.
We are a pioneer in the harnessing of computational technologies to drive biology advancements. Over the last fifteen years, we have made substantial investments in the development of our CodeEvolver ® protein engineering technology platform, the primary source of our competitive advantage. Our technology platform is powered by proprietary, artificial intelligence-based, computational algorithms that rapidly mine our large and continuously growing library of protein variants’ performance attributes. These computational outputs enable increasingly reliable predictions for next generation protein variants to be engineered, enabling delivery of targeted performance enhancements in a time-efficient manner. In addition to its computational prowess, our CodeEvolver ® protein engineering technology platform integrates additional modular competencies, including robotic high-throughput screening and genomic sequencing, organic chemistry and process development, which are all coordinated to create our novel protein innovations.
We use our CodeEvolver ® protein engineering technology platform to engineer custom enzymes. Most of our custom enzymes are intended for use as biocatalysts or protein catalysts. In simple terms, our protein catalysts can accelerate and/or improve yields of chemical reactions. We use our CodeEvolver ® protein engineering technology platform to develop novel enzymes that enable industrial biocatalytic reactions and fermentations. Our technology platform has enabled commercially viable products and processes for the manufacture of pharmaceutical intermediates and active ingredients and fine chemicals.
Our approach to develop commercially viable biocatalytic manufacturing processes begins by conceptually designing the most cost-effective and practical process for a targeted product. We then develop optimized protein catalysts to enable that process design, using our CodeEvolver ® protein engineering platform technology. Engineered protein catalyst candidates, many thousands for each protein engineering project, are then rapidly screened and validated in high throughput under relevant manufacturing operating conditions. This approach results in an optimized protein catalyst enabling cost-efficient processes that typically are relatively simple to run in conventional manufacturing equipment. This also allows for the efficient technical transfer of our process to our manufacturing partners.
The successful embodiment of our CodeEvolver ® protein engineering technology platform in commercial manufacturing processes requires well-integrated expertise in a number of technical disciplines. In addition to those directly involved in practicing our CodeEvolver ® protein engineering platform technology, such as molecular biology, enzymology, microbiology, cellular engineering, metabolic engineering, bioinformatics, biochemistry and high throughput analytical chemistry, our process development projects also involve integrated expertise in organic chemistry, chemical process development, chemical engineering, fermentation process development and fermentation engineering. Our integrated, multi-disciplinary approach to biocatalyst and process development is a critical success factor for our company.
We initially commercialized our CodeEvolver ® protein engineering technology platform and products in the pharmaceuticals market, which remains our primary business focus. Our customers, which include several large global pharmaceutical companies, use our technology, products and services in their manufacturing processes and process development.

7



We have also used the technology to develop protein catalysts for use in the fine chemicals market. The fine chemicals market consists of several large market verticals, including food and food ingredients, animal feed, flavors, fragrances and agricultural chemicals.
More recently, we are also using the CodeEvolver ® protein engineering technology platform to develop early stage, novel biotherapeutic product candidates, both for our customers and for our own business, most notably our lead program for the potential treatment of phenylketonuria ("PKU") disease in humans. PKU is an inherited metabolic disorder in which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient.
We have also used our technology to develop an enzyme for customers using next generation sequencing (“NGS”) and polymerase chain reaction (“PCR/qPCR”) for in vitro molecular diagnostic and genomic research applications. Beta testing for the enzyme was initiated in the second quarter of 2017.
Note 2. Basis of Presentation and Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2016 . The condensed consolidated balance sheet at December 31, 2016 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements.
The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly our financial position as of June 30, 2017 and results of our operations and comprehensive income (loss) for the three and six months ended June 30, 2017 and 2016 , and cash flows for the six months ended June 30, 2017 and 2016 . The interim results are not necessarily indicative of the results for any future interim period or for the entire year. Certain prior period amounts have been reclassified to conform to current period presentation.
The unaudited interim condensed consolidated financial statements include Codexis, Inc. and its wholly owned subsidiaries in the United States, India and the Netherlands. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. We regularly assess these estimates which primarily affect revenue recognition, accounts receivable, inventories, the valuation of investment securities and marketable securities, goodwill arising out of business acquisitions, accrued liabilities, stock awards and the valuation allowances associated with deferred tax assets. Actual results could differ from those estimates and such differences may be material to the condensed consolidated financial statements.
Segment Reporting
Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results beyond revenue goals or plans for levels or components below the consolidated unit level. Accordingly, we have a single reportable segment.
Revenue Recognition
We recognize revenues from the sale of our products, research and development agreements and revenue sharing arrangements. Revenue is recognized when the related costs are incurred and the four basic criteria of revenue recognition are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have been rendered; (3) the fee is

8

fixed or determinable; and (4) collectability is reasonably assured. Where the revenue recognition criteria are not met, we defer the recognition of revenue by recording deferred revenue until such time that all criteria of revenue recognition are met.
We account for revenues from multiple element arrangements, such as license and platform technology transfer agreements and collaborative arrangements in which a licensee may purchase several deliverables, in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Subtopic 605-25, "Multiple Element Arrangements." For new or materially amended multiple element arrangements, we identify the deliverables at the inception of the arrangement and each deliverable within a multiple deliverable revenue arrangement is accounted for as a separate unit of accounting if both of the following criteria are met: (1) the delivered item or items have value to the customer on a standalone basis and (2) for an arrangement that includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control. Revenue allocated to each element is then recognized based on when the basic four revenue recognition criteria are met for each element.
Where a portion of non-refundable up-front fees or other payments received are allocated to continuing performance obligations under the terms of a collaborative arrangement, they are recorded as deferred revenue and recognized as revenue ratably over the term of our estimated performance period under the agreement. We determine the estimated performance periods, and they are periodically reviewed based on the progress of the related program. The effect of any change made to an estimated performance period and, therefore, to revenue recognized, would occur on a prospective basis in the period that the change was made.
Product Sales
Product sales consist of sales of protein catalysts, pharmaceutical intermediates, and Codex ® Biocatalyst Panels and Kits. Product sales are recognized once passage of title and risk of loss has occurred and contractually specified acceptance criteria, if any, have been met, provided all other revenue recognition criteria have also been met. Shipping and handling costs charged to customers are recorded as revenue.
Research and Development
Research and development agreements typically provide us with multiple revenue streams, including research services fees for full time employee ("FTE") research services, up-front licensing fees, technology access fees, contingent payments upon achievement of contractual criteria, and royalty fees based on the licensees' product sales or cost savings achieved by our customers. We perform research and development activities as specified in each respective customer agreement. Payments for services received are not refundable. Certain research agreements are based on a contractual reimbursement rate per FTE working on the project. We recognize revenues from research services as those services are performed over the contractual performance periods. When up-front payments are combined with FTE services in a single unit of accounting, we recognize the up-front payments as revenue using the proportionate performance method of revenue recognition based upon the actual amount of research labor hours incurred relative to the amount of the total expected labor hours to be incurred by us, up to the amount of cash received. In cases where the planned levels of research services fluctuate substantially over the research term, we are required to make estimates of the total hours required to perform our obligations.
We recognize revenues from non-refundable, up-front license fees or technology access payments that are not dependent on any future performance by us when such amounts are earned. If we have continuing obligations to perform under the arrangement, such fees are recorded as deferred revenues and recognized over the estimated period of performance. Estimated performance periods are periodically reviewed based on the progress of the related program. The effect of any change made to an estimated performance period, and therefore to revenue recognized, would occur on a prospective basis in the period that the change was made.
A payment that is contingent upon the achievement of a substantive milestone is recognized in its entirety in the period in which the milestone is achieved. A milestone is an event (i) that can only be achieved based in whole or in part on either our performance or on the occurrence of a specific outcome resulting from our performance, (ii) for which there is, as of the date the arrangement is entered into, substantive uncertainty that the event will be achieved and (iii) results in additional payments being due to us. Milestones are considered substantive when the consideration earned from the achievement of the milestone (i) is commensurate with either our performance to achieve the milestone or the enhancement of the value of the item delivered as a result of a specific outcome resulting from its performance, (ii) relates solely to past performance and (iii) is reasonable relative to all deliverable and payment terms in the arrangement.
We recognize revenues from other contingent payments based on the passage of time or when earned as the result of a customer's performance in accordance with contractual terms and when such payments can be reasonably estimated and collectability of such payments is reasonably assured.

9

We recognize revenues from royalties based on licensees' sales of our products or products using our technologies. Royalties are recognized as earned in accordance with the contractual terms when royalties from licensees can be reasonably estimated and collectability is reasonably assured. For the majority of our royalty revenue, estimates are made using notification of the sale of licensed products from the licensees.
Revenue Sharing Arrangement
We recognize revenues from a revenue sharing arrangement based upon sales of licensed products by our revenue sharing partner Exela PharmSci, Inc. ("Exela") (see Note 11, "Related Party Transactions"). We recognize revenues net of product and selling costs upon notification from our revenue sharing partner of our portion of net profit based on the contractual percentage from the sale of licensed product.
Sales Allowances
Sales allowances primarily relate to product returns and prompt pay sales discounts and are recorded in the same period that the related revenues are recognized, resulting in a reduction in product sales.
Cost of Product Sales
Cost of product sales comprises both internal and third party fixed and variable costs including materials and supplies, labor, facilities and other overhead costs associated with our product sales. Shipping costs are included in our cost of product sales. Such charges were not significant in any of the periods presented.
Cost of Research and Development Services
Cost of research and development services related to FTE services under research and development agreements approximate the research funding over the term of the respective agreements and are included in research and development expense. Costs of services provided under license and platform technology transfer agreements are included in research and development expenses and are expensed in the periods in which such costs are incurred.
Research and Development Expenses
Research and development expenses consist of costs incurred for internal projects, partner-funded collaborative research and development activities, as well as license and platform technology transfer agreements, as mentioned above. These costs include our direct and research-related overhead expenses, which include salaries and other personnel-related expenses (including stock-based compensation), occupancy-related costs, supplies, depreciation of facilities and laboratory equipment and amortization of acquired technologies, as well as external costs, and are expensed as incurred. Costs to acquire technologies that are utilized in research and development and that have no alternative future use are expensed when incurred.
Stock-Based Compensation
We use the Black-Scholes-Merton option pricing model to estimate the fair value of options granted under our equity incentive plans. The Black-Scholes-Merton option pricing model requires the use of assumptions, including the expected term of the award and the expected stock price volatility. The expected term is based on historical exercise behavior on similar awards, giving consideration to the contractual terms, vesting schedules and expectations of future employee behavior. We use historical volatility to estimate expected stock price volatility. The risk-free rate assumption is based on United States Treasury instruments whose terms are consistent with the expected term of the stock options. The expected dividend assumption is based on our history and expectation of dividend payouts.
Restricted Stock Units ("RSUs"), Restricted Stock Awards ("RSAs"), performance vesting options ("PBOs"), and performance-contingent restricted stock units ("PSUs") are measured based on the fair market values of the underlying stock on the dates of grant. The vesting of PBOs and PSUs awarded is conditioned upon the attainment of one or more performance objectives over a specified period and upon continued employment through the applicable vesting date. At the end of the performance period, shares of stock subject to the PBOs and PSUs vest based upon both the level of achievement of performance objectives within the performance period and continued employment through the applicable vesting date.
Stock-based compensation expense is calculated based on awards ultimately expected to vest and is reduced for estimated forfeitures at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The estimated annual forfeiture rates for stock options, RSUs, PSUs, PBOs, and RSAs are based on historical forfeiture experience.

10

The estimated fair value of stock options, RSUs and RSAs are expensed on a straight-line basis over the vesting term of the grant and the estimated fair value of PSUs and PBOs are expensed using an accelerated method over the term of the award once management has determined that it is probable that the performance objective will be achieved. Compensation expense is recorded over the requisite service period based on management's best estimate as to whether it is probable that the shares awarded are expected to vest. Management assesses the probability of the performance milestones being met on a continuous basis.
We have not recognized, and do not expect to recognize in the near future, any excess income tax benefits related to employee stock-based compensation expense as a result of the full valuation allowance on our deferred tax assets including deferred tax assets related to net operating loss carryforwards.
Foreign Currency Translation
The United States dollar is the functional currency for our operations outside the United States. Accordingly, nonmonetary assets and liabilities originally acquired or assumed in other currencies are recorded in United States dollars at the exchange rates in effect at the date they were acquired or assumed. Monetary assets and liabilities denominated in other currencies are translated into United States dollars at the exchange rates in effect at the balance sheet date. Translation adjustments are recorded in other expense in the accompanying condensed consolidated statements of operations. Gains and losses realized from non-U.S. dollar transactions, including intercompany balances not considered as permanent investments, denominated in currencies other than an entity's functional currency are included in other expense in the accompanying condensed consolidated statements of operations.
Cash and Cash Equivalents
We consider all highly liquid investments with maturity dates of three months or less at the date of purchase to be cash equivalents. Our cash and cash equivalents consist of cash on deposit with banks and money market funds. The majority of cash and cash equivalents is maintained with major financial institutions in North America. Deposits with these financial institutions may exceed the amount of insurance provided on such deposits. Cash and cash equivalents totaled $ 28.8 million at June 30, 2017 and were comprised of cash of $18.1 million and money market funds of $10.7 million . At December 31, 2016 , cash and cash equivalents totaled $19.2 million and were comprised of cash of $8.0 million and money market funds of $11.2 million .
Restricted Cash
In 2016, we began the process of liquidating our Indian subsidiary. The local legal requirements for liquidation required us to maintain our subsidiary's cash balance in an account managed by a legal trustee to satisfy our financial obligations. This balance is recorded as non-current restricted cash on the consolidated balance sheets and totaled $0.9 million at June 30, 2017 and $0.8 million at December 31, 2016.
In addition, pursuant to the terms of the lease agreement for our Redwood City, CA facilities, our letters of credit are collateralized by deposit balances of $0.7 million as of June 30, 2017 and $0.8 million as of December 31, 2016 , which is recorded as non-current restricted cash on the consolidated balance sheets (see Note 10, "Commitments and Contingencies" for details).
Inventories
Inventories are stated at the lower of cost or net realizable value. Cost is determined using a weighted-average approach, assuming full absorption of direct and indirect manufacturing costs, or based on cost of purchasing from our vendors. If inventory costs exceed expected net realizable value due to obsolescence or lack of demand, valuation adjustments are recorded for the difference between the cost and the expected net realizable value. These valuation adjustments are determined based on significant estimates.
Marketable Securities
We invest in equity securities and we classify those investments as available-for-sale. These securities are carried at estimated fair value (see Note 5, "Cash Equivalents and Marketable Securities") with unrealized gains and losses included in accumulated other comprehensive income in stockholders' equity. Available-for-sale equity securities with remaining maturities of greater than one year or which we currently do not intend to sell are classified as long-term.
We review several factors to determine whether a loss is other-than-temporary. These factors include, but are not limited to, the intent and ability to retain the investment in the issuer for a period of time sufficient to allow for any anticipated recovery in market value, the length of time and the extent to which the market value of the investment has been less than cost and the

11

financial condition and near-term prospects of the issuer. Unrealized losses are charged against "Other expense" when a decline in fair value is determined to be other-than-temporary. No charge for the other-than-temporary impairment has been recorded in any of the periods presented.
Amortization of purchase premiums and accretion of purchase discounts and realized gains and losses of debt securities are included in interest income. The cost of securities sold is based on the specific identification method.
Fair Value Measurements
Fair value is defined as 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. In determining fair value, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and we consider counterparty credit risk in our assessment of fair value. Carrying amounts of financial instruments, including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, restricted cash, marketable securities, accounts payable, accrued compensation, deferred revenue, and other accrued liabilities, approximate their fair values as of the balance sheet dates because of their generally short maturities.
The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, giving the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
•
Level 1: Inputs that are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
•
Level 2: Inputs (other than quoted prices included in Level 1) that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.
•
Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities and which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date.
Concentrations of Credit Risk
Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable, marketable securities, and restricted cash. Cash that is not required for immediate operating needs is invested principally in money market funds. Cash and cash equivalents are invested through banks and other financial institutions in the United States, India and Netherlands. Such deposits in those countries may be in excess of insured limits.
Impairment of Long-Lived Assets
Our long-lived assets consist of property and fully amortized acquired technology. We test property for recoverability when events or changes in circumstances indicate that its carrying value may not be recoverable. Factors we consider in deciding when to perform an impairment review include significant under-performance of our products in relation to expectations combined with a history of losses or a forecast of continuing losses associated with the use of that property, significant adverse changes in the business climate or legal factors, trends, and significant changes accumulation of costs in excess of the amount originally expected for the acquisition or construction of the property; loss of significant customers or partners; or the current expectation that the property will more likely than not be sold or disposed of significantly before the end its estimated useful life.
We measure the recoverability of property by comparing its carrying value to estimated future undiscounted net cash flows arising from that property. If the property's carrying value is not recoverable through the related undiscounted cash flows, it is considered to be impaired. We measure the impairment by comparing the difference between the property's carrying value and its estimated fair value. During the year ended December 31, 2016 and the six months ended June 30, 2017 , we did no t identify any indicators of potential impairment of our property and concluded that there was no impairment.

12

Goodwill
We determined that we operate in one segment and reporting unit under the criteria in ASC 280, "Segment Reporting." Accordingly, our review of goodwill impairment indicators is performed at the consolidated level. We review goodwill impairment annually in the fourth quarter of each fiscal year and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable.
The goodwill impairment test consists of a two-step process. The first step of the goodwill impairment test used to identify potential impairment compares the fair value of the reporting unit to carrying value. If the fair value of the reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired, and the second step of the impairment test is not required.
We use our market capitalization as an indicator of fair value. We believe that because our reporting unit is publicly traded, the ability of a controlling stockholder to benefit from synergies and other intangible assets that arise from control might cause the fair value of our reporting unit as a whole to exceed its market capitalization. Therefore, we believe that the fair value measurement need not be based solely on the quoted market price of an individual share of our common stock, but also can consider the impact of a control premium in measuring the fair value of its reporting unit.
If we were to use an income approach, it would establish a fair value by estimating the present value of our projected future cash flows expected to be generated from our business. The discount rate applied to the projected future cash flows to arrive at the present value would be intended to reflect all risks of ownership and the associated risks of realizing the stream of projected future cash flows. Our discounted cash flow methodology would consider projections of financial performance for a period of several years combined with an estimated residual value. The most significant assumptions we would use in a discounted cash flow methodology are the discount rate, the residual value and expected future revenue, gross margins and operating costs, along with considering any implied control premium.
Should our market capitalization be less than total stockholders' equity as of our annual test date or as of any interim impairment testing date, we would also consider market comparables, recent trends in our stock price over a reasonable period and, if appropriate, use an income approach to determine whether the fair value of our reporting unit is greater than the carrying amount.
The second step, if required, compares the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit's goodwill exceeds its implied fair value, an impairment charge is recognized in an amount equal to that excess. Implied fair value is the excess of the fair value of the reporting unit over the fair value of all identified assets and liabilities. We base our fair value estimates on assumptions we believe to be reasonable. Actual future results may differ from those estimates.
Goodwill was tested for impairment in the fourth quarter of 2016 . We determined that the fair value of the reporting unit exceeded the carrying value and no impairment existed. Based on the results obtained, we concluded there was no impairment of our goodwill as of December 31, 2016 . During the six months ended June 30, 2017 , we did no t identify any indicators of potential impairment of goodwill or new information that would have a material impact on the forecast or the impairment analysis prepared as of December 31, 2016 .
Income Taxes
We account for income taxes using the asset and liability approach. Under this approach, deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements using enacted tax rates and tax laws in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are provided against deferred tax assets that are not likely to be realized.
We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of tax credits, benefits and deductions and in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expenses for tax and financial statement purposes. Significant changes to these estimates may result in an increase or decrease to our tax provision in a subsequent period.
In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will be realized on a jurisdiction by jurisdiction basis. The ultimate realization of deferred tax assets is dependent upon the generation of taxable income in the future. We have recorded a deferred tax asset in jurisdictions where ultimate realization of deferred tax assets is more likely than not to occur.

13

We make estimates and judgments about future taxable income that are based on assumptions that are consistent with our plans and estimates. Should the actual amounts differ from our estimates, the amount of our valuation allowance could be materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded in the income statement for the periods in which the adjustment is determined to be required.
We account for uncertainty in income taxes as required by the provisions of ASC Topic 740, "Income Taxes," which clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires us to determine the probability of various possible outcomes. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes. We recognize interest and penalties as a component of our income tax expense.
The Tax Reform Act of 1986 and similar state provisions limit the use of net operating loss carryforwards in certain situations where equity transactions result in a change of ownership as defined by Internal Revenue Code Section 382. In the event we should experience such a change of ownership, utilization of our federal and state net operating loss carryforwards could be limited. We maintain a full valuation allowance against net deferred tax assets as we believe that it is more likely than not that the majority of deferred tax assets will not be realized.
Benefit from income taxes was $42,000 and $18,000 for the three and six months ended June 30, 2017 , respectively. Benefit from income taxes was $26,000 and $15,000 for the three and six months ended June 30, 2016 , respectively.
Recently Issued Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the FASB or other standards setting bodies that are adopted by us as of the specified effective date. Unless otherwise discussed, we believe that the impact of recently issued standards that are not yet effective will not have a material impact on our consolidated financial statements upon adoption.
In May 2014, the FASB issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method . The guidance supersedes our existing revenue recognition standard and requires revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration we expect to be entitled to in exchange for those goods or services. The guidance requires expanded disclosures regarding revenue and contracts with customers. The guidance permits two implementation approaches: (i) retrospective application of the standard with restatement of prior years and (ii) retrospective application of the standard with application of certain practical expedient provisions. We intend to elect a modified retrospective method on adoption of this guidance with the initial application in January 2018. The modified retrospective method requires us to apply the new revenue guidance to the financial results in the year of adoption, concurrently recording a cumulative-effect adjustment to the opening balance of retained earnings. The opening adjustment to retained earnings will be determined on the basis of the impact of the new guidance’s application on contracts that were not completed as of the date of initial application.
We are reviewing the impact of this guidance across our revenue-related activities and are in the processing of determining the impact of the new guidance on our revenue recognition practices, business process and internal controls, and on our consolidated financial statements. We enter into research and development agreements which may contain multiple performance obligations. Under the new guidance, an agreement's transaction price will be allocated to all separately identifiable performance obligations in the arrangement and revenue will be recognized as we satisfy each performance obligation according to our evaluation of the timing our customer obtained control of deliverables according to the terms of the agreement. Revenue recognition related to product sales will be recognized once passage of title and risk of loss has occurred, contractually specified acceptance criteria are met, and collectability is probable. Variable revenue from revenue sharing arrangements will be recognized when the consideration becomes probable based on notification from our revenue sharing partners. The adoption of this guidance is expected to have a material impact on our consolidated financial statement disclosures and disclosure controls and will include qualitative and quantitative information about contracts with customers, and significant judgments and changes in judgments made in applying the guidance to contracts, and assets recognized from costs to obtain or fulfill contracts. We continue to monitor additional changes, modifications, clarifications or interpretations undertaken by the FASB, which may impact our current conclusions. In addition, we continue to monitor other changes, such as

14

changes in our business, new collaboration arrangements, business combinations, etc., which may impact our current conclusions prior to the adoption date.
In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities.” This guidance principally affects accounting standards for equity investments, financial liabilities where the fair value option has been elected, and the presentation and disclosure requirements for financial instruments. Upon the effective date of the new guidance, all equity investments in unconsolidated entities, other than those accounted for using the equity method of accounting, will generally be measured at fair value through earnings. There will no longer be an available-for-sale classification and therefore, no changes in fair value will be reported in other comprehensive income (loss) for equity securities with readily determinable fair values. The new guidance on the classification and measurement will be effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years and early adoption is permitted. The Company is in the process of evaluating the impact of the adoption of ASU 2016-01 on the consolidated financial statements and currently anticipates the new guidance would impact its consolidated statements of operations and consolidated statements of comprehensive income as the Company’s marketable equity securities, are currently classified as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income.
In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)," which replaces prior lease guidance (Topic 840.) This guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and lease liability on the balance sheet 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 Consolidated Statement of Operations. The guidance also eliminates today’s real estate-specific provisions for all entities. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. Entities have the option to use certain practical expedients. Full retrospective application is prohibited. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of this accounting standards updated on our Consolidated Financial Statements. We expect that upon adoption, ROU assets and lease liabilities will be recognized in the balance sheet in amounts that will be material.
In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," which amends the FASB's guidance on the impairment of financial instruments. The ASU adds to GAAP an impairment model (known as the "current expected credit loss model") that is based on expected losses rather than incurred losses. ASU 2016-13 is effective for annual reporting periods ending after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The adoption of ASU 2016-13 is not expected to have a material impact on our consolidated financial statements and related disclosures.
In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments," which provides the FASB's guidance on certain cash flow statements items. ASU 2016-15 is effective for fiscal reporting periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted including adoption in an interim period. The adoption of ASU 2016-15 is not expected to have a material impact on our consolidated financial statements and related disclosures.
In November 2016, the FASB issued ASU No. 2016-18, "Statement of Cash Flows (Topic 230) Restricted Cash a consensus of the FASB Emerging Issues Task Force." The standard requires restricted cash and restricted cash equivalents to be included with cash and cash equivalents on the statement of cash flows. The new standard is expected to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. We are currently evaluating the impact of adopting ASU 2016-18 on our consolidated financial statements and related disclosures.
In January 2017, the FASB issued ASU No. 2017-01 "Business Combinations (Topic 805): Clarifying the Definition of a Business". The guidance requires the use of a framework to determine whether a set of assets and activities constitutes an acquired or a sold business. The guidance is effective January 1, 2018 and must be adopted prospectively. Early adoption is encouraged.
In January 2017, the FASB issued ASU No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." The amendments eliminate Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. In addition, income tax effects

15

from any tax deductible goodwill on the carrying amount of the reporting unit should be considered when measuring the goodwill impairment loss, if applicable. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The new standard is expected to be effective for fiscal years beginning after December 15, 2019, with early adoption permitted. We are currently evaluating the impact of adopting ASU 2017-04 on our consolidated financial statements and related disclosures.
In May 2017, the FASB issued ASU No. 2017-09, "Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting." The amendments provide guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 718. The new standard is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2017 with early adoption permitted. We are currently evaluating the impact of adopting ASU 2017-09 on our consolidated financial statements and related disclosures.
Note 3. Net Income (Loss) per Share
Basic net income (loss) per share is computed by dividing the net income (loss) by the weighted-average number of shares of common stock outstanding, less RSAs subject to forfeiture. Diluted net income (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding plus all additional common stock shares that would have been outstanding, assuming dilutive potential common stock shares had been issued for other dilutive securities. For periods of net loss, diluted and basic net loss per share are identical since potential common stock shares are excluded from the calculation, as their effect was anti-dilutive.
The following table sets forth the competition of basic and diluted net income (loss) per share during three and six months ended June 30, 2017 and 2016 (in thousands, except per share amounts):

Note 4. Collaborative Arrangements
GSK Platform Technology Transfer, Collaboration and License Agreement
In July 2014, we entered into a CodeEvolver ® platform technology transfer collaboration and license agreement (the “GSK CodeEvolver ® Agreement”) with GlaxoSmithKline ("GSK"). Pursuant to the terms of the agreement, we granted GSK a non-exclusive license to use the CodeEvolver ® protein engineering technology platform to develop novel enzymes for use in the manufacture of GSK's pharmaceutical and health care products.
We received a $6.0 million up-front licensing fee upon signing the GSK CodeEvolver ® Agreement and subsequently a $5.0 million non-creditable, non-refundable milestone payment upon achievement of the first milestone in 2014. In September 2015, we achieved the second milestone of the agreement and earned milestone revenue of $6.5 million . In April 2016, we completed the full transfer of the CodeEvolver ® protein engineering platform technology and earned milestone revenue of $7.5 million . We also have the potential to receive additional back end milestone payments that range from $5.75 million to $38.5 million per project based on GSK's successful application of the licensed technology. The back end milestone payments are not deemed substantive milestones due to the fact that the achievement of the event underlying the payment predominantly relates to GSK's performance of future development and commercialization activities.
In the third quarter of 2016, we earned and recognized the first contingent payment under the agreement related to the development of an enzyme for an already-commercialized product. In addition, we are eligible to receive royalties based on net sales, if any, of a limited set of products developed by GSK using the CodeEvolver ® protein engineering technology platform.
The term of the GSK CodeEvolver ® Agreement continues, unless earlier terminated, until the expiration of all payment obligations under the GSK CodeEvolver ® Agreement. GSK can terminate the GSK CodeEvolver ® Agreement by providing 90 days written notice to us.
Under the GSK CodeEvolver ® Agreement, the significant deliverables were determined to be the license, platform technology transfer, and contingent obligation to supply GSK with enzymes manufactured by us at GSK’s expense. We determined that the license did not have stand-alone value. In addition, we determined that the license and the platform technology transfer and our participation in joint steering committee activities in connection with the platform technology transfer represent a single unit of accounting. Our participation in the joint steering committee does not represent a separate unit of accounting because GSK could not negotiate for and/or acquire these services from other third parties and our participation on the joint steering committee is coterminous with the technology transfer period. Amounts to be received under the supply arrangement, if any, described above will be recognized as revenue to the extent GSK purchases enzymes from us.
The up-front license fee of $6.0 million was recognized ratably over the technology transfer period of three years from July 2014. We recognized all deferred revenue from GSK upon completion of the technology transfer in April 2016. We recognized none of the up-front license fees for the three and six months ended June 30, 2017 , compared to $2.5 million and $3.0 million for the three and six months ended June 30, 2016 , respectively, as research and development revenue.
Merck Platform Technology Transfer and License Agreement
In August 2015, we entered into a CodeEvolver ® platform technology transfer and license agreement (the "Merck CodeEvolver ® Agreement") with Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc. (collectively, "Merck"). The Merck CodeEvolver ® Agreement allows Merck to use the CodeEvolver ® protein engineering technology platform in the field of human and animal healthcare.
Under the terms of the Merck CodeEvolver ® Agreement, we granted to Merck a non-exclusive worldwide license to use the CodeEvolver ® protein engineering technology platform to research, develop and manufacture novel enzymes for use by Merck in its internal research programs ("Merck Non-Exclusive Field"). The license to Merck is exclusive for the research, development and manufacture of novel enzymes for use by Merck in the chemical synthesis of therapeutic products owned or controlled by Merck ("Merck Exclusive Field"). Merck has the right to grant sublicenses to affiliates of Merck and, in certain limited circumstances, to third parties. We also granted to Merck a license to make or have made products manufactured using the CodeEvolver ® protein engineering technology platform with a right to grant sublicenses solely to affiliates of Merck, contract manufacturing organizations and contract research organizations. The manufacturing license is exclusive in the Merck Exclusive Field and non-exclusive in the Merck Non-Exclusive Field. The licenses are subject to certain limitations based on pre-existing contractual obligations that apply to the technology and intellectual property that are the subject of the license grants. The licenses do not permit the use of the CodeEvolver ® protein engineering technology platform to discover any therapeutic enzyme, diagnostic product or vaccine. In addition, Merck is prohibited from using the CodeEvolver ® protein engineering technology platform to develop or produce enzymes or any other compounds for or on behalf of any third parties

17

except in a very limited manner when Merck divests a therapeutic product that is manufactured using an enzyme developed using the CodeEvolver ® protein engineering technology platform.
Under the Merck CodeEvolver ® Agreement, we transferred the CodeEvolver ® protein engineering technology platform to Merck over the period from August 2015 through September 2016. As part of this technology transfer, we provided to Merck our proprietary enzymes, proprietary protein engineering protocols and methods, and proprietary software algorithms.
The licenses to Merck are granted under patents, patent applications and know-how that we own or control as of the effective date of the Merck CodeEvolver ® Agreement and that cover the CodeEvolver ® protein engineering technology platform. Any improvements to the CodeEvolver ® protein engineering technology platform during the technology transfer period are also included in the license grants from Codexis to Merck. Following the technology transfer period, Merck can exercise annual options that, upon payment of certain option fees, would extend Merck's license to include certain improvements to the CodeEvolver ® protein engineering technology platform that arise during the three -year period that begins at the end of the technology transfer period.
Under the Merck CodeEvolver ® Agreement, we will own any improvements to our protein engineering methods, processes and algorithms that arise and any enzyme technology or process technology that are developed during a technology transfer project, an evolution program or additional services. Merck will own (the "Merck-Owned Technology") (a) any enzyme technology that is developed solely by Merck under the Merck CodeEvolver ® Agreement using the CodeEvolver ® protein engineering technology platform (a "Project Enzyme") and (b) the methods of use of any Project Enzyme or any enzyme developed jointly by Merck and us using the CodeEvolver ® protein engineering technology platform. Merck granted to us a worldwide, non-exclusive, fully paid-up, royalty-free license, with the right to grant sublicenses, to use the Merck-Owned Technology outside of the Merck Exclusive Field.
For each API that Merck manufactures using an enzyme developed with the CodeEvolver ® protein engineering technology platform, we will have a right of first refusal to supply Merck with the enzyme used to manufacture the API if Merck outsources the supply of the enzyme. Our right of first refusal applies during the period that begins on the completion of a phase III clinical trial for the product containing the API and ends five years following regulatory approval for such product.
The Merck CodeEvolver ® Agreement has a term that continues, unless earlier terminated, until the expiration of all payment obligations under the agreement. Merck may terminate the Merck CodeEvolver ® Agreement by providing 90 days written notice to us. We can terminate the Merck CodeEvolver ® Agreement by providing 30 days written notice to Merck if we determine, pursuant to our contractual audit rights under the Merck CodeEvolver ® Agreement, that Merck has repeatedly failed to make required payments to us and/or materially underpaid us an amount due under the Merck CodeEvolver ® Agreement. In the event the Merck CodeEvolver ® Agreement is terminated earlier by Merck, or by us due to an uncured material breach by Merck, or if Merck sells or transfers to a third party any Merck business or facility that includes any of our proprietary materials, information or technology, we have the right to conduct an audit of Merck's facilities to confirm that all of our proprietary materials, information and technology have been destroyed. The Merck CodeEvolver ® Agreement contains indemnification provisions under which Merck and we have agreed to indemnify each other against certain third party claims.
We received a $5.0 million up-front license fee upon execution of the Merck CodeEvolver ® Agreement, which was recognized ratably over the estimated platform technology transfer period of two years. The technology transfer was completed in September 2016 and all remaining deferred revenue was recognized. We have the potential to receive payments of up to a maximum of $15.0 million for each commercial active pharmaceutical ingredient ("API") that is manufactured by Merck using one or more novel enzymes developed by Merck using the CodeEvolver ® protein engineering technology platform.
We recognized no license fees for the three and six months ended June 30, 2017 , compared to $0.6 million and $1.3 million for the three and six months ended June 30, 2016 , respectively, as research and development revenue. Additionally, we recognized research and development revenues of $0.9 million and $1.8 million for the three and six months ended June 30, 2017 , respectively, compared to $0.5 million and $0.7 million for the three and six months ended June 30, 2016 , respectively, for various research projects under our collaborative arrangement.
Merck Sitagliptin Catalyst Supply Agreement
In February 2012, we entered into a five -year Sitagliptin Catalyst Supply Agreement ("Sitagliptin Catalyst Supply Agreement") with Merck whereby Merck may obtain commercial scale substance for use in the manufacture of Januvia ® , its product based on the active ingredient sitagliptin. In December 2015, Merck exercised its option under the terms of the Sitagliptin Catalyst Supply Agreement to extend the agreement for an additional five years through February 2022.
Effective as of January 2016, we and Merck amended the Sitagliptin Catalyst Supply Agreement to prospectively provide for variable pricing based on the cumulative volume of sitagliptin purchased by Merck under the Sitagliptin Catalyst Supply

18

Agreement and to allow Merck to purchase a percentage of its requirements for sitagliptin from a specified third-party supplier. Merck has the right to terminate the Sitagliptin Catalyst Supply Agreement at any time after January 1, 2018 by giving us 24 months’ advance written notice. In June 2017, we completed a contractual milestone by qualifying the specified third-party enzyme supplier and recognized $0.3 million as research and development revenue.
The Sitagliptin Catalyst Supply Agreement requires Merck to pay an annual license fee for the rights to the sitagliptin technology each year for the term of the agreement. Amounts of annual license fees are based on contractually agreed prices and are on a declining scale. Prior to December 2015, the aggregate license fee for the initial five year period was being recognized ratably over the initial five year term of the Sitagliptin Catalyst Supply Agreement as collaborative research and development revenue. Due to the amendment entered in December 2015 as noted above, we revised our performance period in December 2015 and began recognizing the remaining unamortized portion of the license fee and the aggregate license fees for the second five year period over the revised period on a straight line basis.
We recognized license fees of $0.3 million and $0.7 million for the three and six months ended June 30, 2017 , respectively, and $0.3 million and $0.7 million for the three and six months ended June 30, 2016 , respectively, as research and development revenues. We had a deferred revenue balance from Merck related to license fees of $2.2 million at June 30, 2017 and $1.3 million at December 31, 2016 . In addition, pursuant to the terms of the agreement, Merck may purchase supply from us for a fee based on contractually stated prices and we recognized $3.2 million and $5.0 million for the three and six months ended June 30, 2017 , respectively, compared to $1.1 million and $2.7 million for the three and six months ended June 30, 2016 in product sales under this agreement.
Biopharmaceutical Collaborative Development Agreement
In May 2015, we entered into a collaborative development agreement with a leading global biopharmaceutical company. Under the terms of the agreement, we used our CodeEvolver ® protein engineering platform technology to develop a novel enzyme for use in our partner’s therapeutic development program. We recognized revenues of $33,000 and $0.1 million for the three and six months ended June 30, 2017 , respectively, compared to $0.4 million and $1.8 million for the three and six months ended June 30, 2016 as collaborative research and development revenues. Under the agreement, we have the potential to receive additional license fees and milestone payments.
Enzyme Supply Agreement
In November 2016, we entered into a supply agreement whereby our customer may purchase quantities of one of our proprietary enzymes for use in its commercial manufacture of a product. Pursuant to the supply agreement, we received an upfront payment of $0.75 million in December 2016, which we accordingly recorded as deferred revenues. Such upfront payment will be recognized over the period of the supply agreement as the customer purchases our proprietary enzyme. As of June 30, 2017 and December 31, 2016 , we had deferred revenue from the supply agreement of $0.7 million . Under the agreement, we recognize product revenues for quantities of enzyme sold to our customer when all revenue recognition criteria are met.
Research and Development Agreement
In March 2017, we entered into a multi-year research and development services agreement with a fine chemicals customer. Under the agreement, we have the potential to receive research and development revenues and milestone payments based on the customer's decision to continue the development process. We received an upfront payment of $3.0 million , which is recognized ratably over the maximum term of the services period of 21 months, of which we recognized $0.4 million in the three and six months ended June 30, 2017 . We also recognized 0.4 million of revenue for research and development services on a net payment received under the agreement for the three and six months ended June 30, 2017 . Total revenue recognized under the research and development agreement for the three and six months ended June 30, 2017 was $0.8 million . As of June 30, 2017 , we had deferred revenue from the development services agreement of $2.6 million .

Note 8. Stock-Based Compensation
Equity Incentive Plans
In March 2010, our board of directors (the "Board") and stockholders approved the 2010 Equity Incentive Award Plan (the "2010 Plan"), which became effective upon the completion of our initial public offering in April 2010. The number of shares of our common stock available for issuance under the 2010 Plan is equal to 1,100,000 shares plus any shares of common stock reserved for future grant or issuance under our 2002 Stock Plan (the "2002 Plan") that remained unissued at the time of completion of the initial public offering. The 2010 Plan also provides for automatic annual increases in the number of shares reserved for future issuance. All grants will reduce the 2010 Plan reserve by one share for every share granted.
The 2010 Plan provides for the grant of incentive stock options, non-statutory stock options, RSUs, RSAs, PSUs, PBOs, stock appreciation rights, and stock purchase rights to our employees, non-employee directors and consultants.
Stock Options
The option exercise price for incentive stock options is at least 100% of the fair value of our common stock on the date of grant and the option exercise price for nonstatutory stock options is at least 85% of the fair value of our common stock on the date of grant, as determined by the Board. If, at the time of a grant, the optionee directly or by attribution owns stock possessing more than 10% of the total combined voting power of all of our outstanding capital stock, the exercise price for these options must be at least 110% of the fair value of the underlying common stock. Stock options granted to employees generally have a maximum term of 10 years and vest over a four year period from the date of grant, of which 25% vest at the end of one year, and 75% vest monthly over the remaining three years. We may grant options with different vesting terms from time to time. Unless an employee's termination of service is due to disability or death, upon termination of service, any unexercised vested options will be forfeited at the end of three months or the expiration of the option, whichever is earlier.

21

Restricted Stock Units
We also grant employees RSUs, which generally vest over either a three year period with one-third of the shares subject to the RSUs vesting on each yearly anniversary of the vesting commencement date or over a four year period with 25% of the shares subject to the RSU vesting on each yearly anniversary of the vesting commencement date, in each case contingent upon such employee’s continued service on such vesting date. RSUs are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. We may grant RSUs with different vesting terms from time to time.
Performance-contingent Restricted Stock Units and Performance Vesting Options
In 2015 and 2016, the compensation committee of the Board approved, and, in February 2017 solely in respect of non-executive employees, delegated to our Chief Executive Officer the authority to approve grants of PSUs. In February 2017, the compensation committee of the Board also approved grants of PBOs and PSUs to our executives. The PSUs and PBOs vest based upon both the successful achievement of certain corporate operating milestones in specified timelines and continued employment through the applicable vesting date. When the performance goals are deemed to be probable of achievement for these types of awards, recognition of stock-based compensation expense commences.
In the first quarter of 2017, our compensation committee and Chief Executive Officer granted PSUs (“2017 PSUs”) and our compensation committee granted PBOs (“2017 PBOs”), each of which commence vesting based upon the achievement of various weighted performance goals, including revenue growth, fundraising, service revenue, new platform license revenue, and strategic advancement of biotherapeutics pipeline. The number of shares underlying the 2017 PSUs and 2017 PBOs that are eligible to vest are based upon our achievement of the performance goals and, once the number of shares eligible to vest is determined, those shares vest in two equal installments with 50% vesting upon achievement and the remaining 50% vesting on the first anniversary of achievement, in each case, subject to the recipient’s continued service through the applicable vesting date. If the performance goals are achieved at the threshold level, the number of shares eligible to vest in respect of the 2017 PSUs and the 2017 PBOs would be equal to half the number of 2017 PSUs granted and one-quarter the number of shares underlying the 2017 PBOs granted. If the performance goals are achieved at the target level, the number of shares eligible to vest in respect of the 2017 PSUs and 2017 PBOs would be equal to the number of 2017 PSUs granted and half of the shares underlying the 2017 PBOs granted. If the performance goals are achieved at the superior level, the number of shares eligible to vest in respect of the 2017 PSUs would be equal to two times the number of 2017 PSUs granted and equal to the number of 2017 PBOs granted. The number of shares issuable upon achievement of the performance goals at the levels between the threshold and target levels for the 2017 PSUs and 2017 PBOs or between the target level and superior levels for the 2017 PSUs would be determined using linear interpolation. Achievement below the threshold level would result in no shares being eligible to vest in respect of the 2017 PSUs and 2017 PBOs. As of June 30, 2017 , we estimated that the 2017 PSU and 2017 PBOs performance goals would be achieved at 119.0% of the target level. Accordingly, we recognized expense to reflect the target level.
In 2016, we awarded PSUs ("2016 PSUs") based upon the achievement of various weighted performance goals, including revenue growth, non-GAAP net income growth, new licensing collaborations, new R&D service revenue arrangements and novel therapeutic enzymes advancement. In the first quarter of 2017, we determined that the 2016 PSU performance goals had been achieved at 142.3% of the target level, and recognized expenses accordingly. Accordingly, one-half of the shares underlying the 2016 PSUs vested in the first quarter of 2017 and one-half of the shares underlying the 2016 PSUs will vested in the first quarter of 2018, in each case subject to the recipient’s continued service on each vesting date. No PBOs were awarded in 2016.
In 2015, we awarded PSUs ("2015 PSUs") based upon the achievement of various weighted performance goals, including revenue growth, non-GAAP net income growth, new licensing collaborations, and securing a drug development partnership, with other terms similar to the 2014 PSUs and 2016 PSUs. In the first quarter of 2016, we determined that the 2015 PSU performance goals had been achieved at 92.8% of the target level, and recognized expenses accordingly. One-half of the shares underlying the 2015 PSUs vested in the first quarter of each of 2016 and 2017, subject to the recipient’s continued service on each vesting date. No PBOs were awarded in 2015.

Note 10. Commitments and Contingencies
Operating Leases
Our headquarters are located in Redwood City, California, where we occupy approximately 107,200 square feet of office and laboratory space in four buildings within the same business park of Metropolitan Life Insurance Company ("Met-Life"). We entered into the initial lease with Met-Life for a portion of this space in 2004 and the lease has been amended multiple times since then to adjust space and amend the terms of the lease, with the latest amendment in October 2016. The various terms for the spaces under the lease had expiration dates that range from January 2020 through January 2022 . As described further below, in October 2016, we exercised an option to extend our lease of certain spaces through January 2022. Beginning in February 2014, we have subleased office space to different subtenants with separate options to extend the subleases. If all such options to extend were exercised, these agreements would expire at various dates through November 2019.
We incurred $3.6 million of capital improvement costs related to the facilities leased from Met-Life through December 31, 2012. During 2011 and 2012, we requested and received $3.1 million of reimbursements from the landlord from the tenant improvement and HVAC allowances for the completed construction. The reimbursements were recorded once cash was received and are amortized on a straight line basis over the term of the lease as a reduction in rent expense. The remaining lease incentive obligation was $1.1 million and $1.3 million at June 30, 2017 and December 31, 2016 , respectively, and is reflected as liabilities on the consolidated balance sheet. Rent expense for the Redwood City properties is recognized on a straight-line basis over the term of the lease.
We are required to restore certain areas of the Redwood City facilities that we are renting to their original form. We are expensing the asset retirement obligation over the terms of the respective leases. We review the estimated obligation each reporting period and make adjustments if our estimates change. We recorded asset retirement obligations of $0.4 million as of both June 30, 2017 and December 31, 2016 , which are included in other liabilities on the consolidated balance sheets.

24

Accretion expense related to our asset retirement obligations was nominal in the three and six months ended June 30, 2017 and June 30, 2016 .
Pursuant to the terms of the amended lease agreement, we exercised our right to deliver a letter of credit in lieu of a security deposit. The letters of credit are collateralized by deposit balances held by the bank in the amount of $0.7 million as of June 30, 2017 and $0.8 million as of December 31, 2016 . These deposits are recorded as restricted cash on the consolidated balance sheets.
Rent expense was $1.0 million and $1.9 million during the three and six months ended June 30, 2017 , respectively, partially offset by sublease income of $0.3 million and $0.7 million , respectively. Rent expense was $0.8 million and $1.7 million during the three and six months ended June 30, 2016 , respectively, partially offset by sublease income of $0.3 million and $0.5 million , respectively.
Capital Leases
In December 2016, we entered into a three -year financing lease agreement with a third party supplier for the purchase of laboratory equipment that was partially financed through a capital lease of approximately $0.4 million . The lease became effective upon delivery of the equipment, which occurred in February 2017, and the term of the lease is three years from the effective date. This financing agreement was accounted for as a capital lease due to the bargain purchase option at the end of the lease.
In April 2017, we entered into a three -year financing lease agreement with a third party supplier for the purchase of information technology equipment for approximately $0.3 million . The effective date of the lease was May 19, 2017 and the term of the lease is three years. This financing agreement was accounted for as a capital lease due to the bargain purchase option at the end of the lease.

Credit Facility
Effective June 30, 2017, we entered into a credit facility (the “Credit Facility”) consisting of term loans (“Term Debt”) totaling up to $10.0 million , and advances (“Advances”) under a revolving line of credit (“Revolving Line of Credit”) totaling up to $5.0 million with an accounts receivable borrowing base of 80% of eligible accounts receivable. At June 30, 2017, we have not drawn from the Credit Facility. We may draw on the Term Debt at any time prior to June 30, 2018, subject to customary conditions for funding including, among others, that no event of default exists. We may draw on the Revolving Line of Credit at any time prior to the maturity date. On July 1, 2021 , any loans for Term Debt mature and the Revolving Line of Credit terminates. Term Debt bears interest through maturity at a variable rate based on the London Interbank Offered Rate plus 3.60% . Advances under the Revolving Line of Credit bear interest at a variable annual rate equal to the greater of (i) 1.00% above the prime rate and (ii) 5.00% .
The Credit Facility allows for interest-only payments on Term Debt through February 1, 2019 . Interest-only payments on Term Debt may be continued through August 1, 2019 , provided we enter into a licensing, commercialization, corporate collaboration or similar monetization agreement on which we receive at least a $6.0 million upfront cash receipt and/or milestone cash payments on or before January 15, 2019. Monthly payments of principal and interest on the Term Debt are required following the applicable amortization date. We may elect to prepay in full the Term Debt and Advances under the Revolving Line of Credit at any time. Prepayments of Term Debt and early termination of the Revolving Line of Credit are subject to prepayment and final payment fees are as follows:
Term Debt
Revolving Line of Credit
Through and including the first anniversary of the funding date of the first Term Debt drawn
2.0%
After the first anniversary of the funding date of the first Term Debt drawn and before the maturity date
1.0%
On the earliest to occur of the maturity date, the acceleration of Term Debt drawn or prepayment of Term Debt drawn
5.5%
Through and including the first anniversary of the closing date
3.0%
After the first anniversary of the closing date through and including the second anniversary of the closing date
2.0%
After the second anniversary of the closing date through and including the third anniversary of the closing date
1.0%
Our obligations under the Credit Facility are secured by a lien on substantially all of our personal property other than our intellectual property. The Credit Facility includes a number of customary covenants and restrictions which require us to comply with certain financial covenants including achieving consolidated product revenues levels at minimum levels as set forth in the Credit Facility through December 2018 and on and after January 2019 , in each case unless we maintain certain minimum cash levels with the lender in an amount equal to or greater than six times the sum of the average six -month trailing operating cash flow net outlay plus the average monthly principal due and payable in the immediately succeeding three -month period. The Credit Facility places various restrictions on the Company’s transferring collateral, incurring additional indebtedness, engaging in mergers or acquisitions, paying dividends or making other distributions, making investments, creating liens and selling assets and permitted assets to be held at foreign subsidiaries above specified caps, in each case subject to certain exceptions. A failure to comply with these covenants could permit the lender to exercise remedies against us and the collateral securing the Credit

26

Facility, including foreclosure of our properties securing the Credit Facilities and our cash. At June 30, 2017, we were in compliance with the covenants for the Credit Facility.
Legal Proceedings
On February 19, 2016, we filed a complaint against EnzymeWorks, Inc., a California corporation, EnzymeWorks, Inc., a Chinese corporation (collectively with the California corporation, “EnzymeWorks”), and Junhua “Alex” Tao (collectively with EnzymeWorks, the “Defendants”) in the United States District Court for the Northern District of California. On April 29, 2016, we filed a First Amended Complaint. The First Amended Complaint alleges that the Defendants have engaged in willful patent infringement, trade secret misappropriation, breach of contract, intentional interference with contractual relations, intentional interference with prospective economic relations and statutory and common law unfair competition. We have sought injunctive relief, monetary damages, treble damages, restitution, punitive damages and attorneys’ fees. On May 13, 2016, the Defendants filed a Partial Motion to Dismiss the claims for breach of contract, intentional interference with contractual relations, intentional interference with prospective economic relations, statutory unfair competition, and common law unfair competition in the First Amended Complaint. We opposed the Defendant’s Partial Motion to Dismiss. On August 11, 2016, the judge issued an order that denied the Defendants’ Partial Motion to Dismiss with respect to all five claims and in all relevant parts, and granted the motion with respect to certain underlying arguments. The Defendants filed their Answer on September 1, 2016, stating that the Defendants would not contest infringement of the asserted patents and denying the trade secret claim and other non-patent claims. There are no counterclaims. On September 21, 2016, the parties filed a stipulation in which the Defendants agreed not to contest our construction of certain patent claim terms and vacating deadlines related to the claim construction proceedings. The Court entered the stipulated order on September 26, 2016. On July 19, 2017, Defendants filed a Stipulation with Proposed Order seeking leave to file Defendants’ First Amended Answer to add an affirmative defense of “competition privilege.” The Court entered the Order granting leave for Defendants to file the First Amended Answer on July 24, 2017. On July 31, 2017, the parties filed a stipulation acknowledging that EnzymeWorks had not denied or disputed its infringement of each of Codexis’ ten asserted patents, or the validity of those patents. Based on this stipulation, on August 8, 2017, the Court entered an order granting Codexis summary judgment on its claims of patent infringement against EnzymeWorks. Additional issues remain to be resolved, including Tao’s individual liability for the infringement, Codexis’ claims that the infringement was willful, the amount of damages to be awarded to Codexis, and the trade secret and other non-patent claims. The case is currently in fact discovery, which is scheduled to close on August 30, 2017. We are unable to determine when this litigation will be resolved or its ultimate outcome.
Other than our litigation against the Defendants, we are not currently a party to any material litigation or other material legal proceedings.
Indemnifications
We are required to recognize a liability for the fair value of any obligations we assume upon the issuance of a guarantee. We have certain agreements with licensors, licensees and collaborators that contain indemnification provisions. In such provisions, we typically agree to indemnify the licensor, licensee and collaborator against certain types of third party claims. The maximum amount of the indemnifications is not limited. We accrue for known indemnification issues when a loss is probable and can be reasonably estimated. There were no accruals for expenses related to indemnification issues for any periods presented.

Business Overview
We discover, develop and sell proteins that deliver value to our clients in a growing set of industries. We view proteins as a vast untapped source of value-creating materials, and we are using our proven technologies, which we have been continuously improving over our fifteen-year history, to commercialize an increasing number of novel proteins, both as proprietary Codexis products and in partnership with our customers.
Many companies have historically used naturally occurring proteins to produce or enhance goods used in everyday life. Despite the growing number of commercial applications of naturally occurring proteins across many industries, the inherent limitations of naturally occurring proteins frequently restrict their commercial use. Through the application of our proprietary CodeEvolver ® protein engineering technology platform, we are able to engineer novel proteins to overcome these restrictions, thereby adding value or opening up new prospects for our existing and potential customers’ products, processes or businesses. We have developed new proteins that are significantly more stable and/or active in our customers' commercial applications than proteins derived from nature.
We are a pioneer in the harnessing of computational technologies to drive biology advancements. Over the last fifteen years, we have made substantial investments in the development of our CodeEvolver ® protein engineering technology platform, the primary source of our competitive advantage. Our technology platform is powered by proprietary, artificial intelligence-based, computational algorithms that rapidly mine our large and continuously growing library of protein variants’ performance attributes. These computational outputs enable increasingly reliable predictions for next generation protein variants to be engineered, enabling delivery of targeted performance enhancements in a time-efficient manner. In addition to its computational prowess, our CodeEvolver ® protein engineering technology platform integrates additional modular competencies, including robotic high-throughput screening and genomic sequencing, organic chemistry and process development which are all coordinated to create our novel protein innovations.
We use our CodeEvolver ® protein engineering technology platform to engineer custom enzymes. Most of our custom enzymes are intended for use as biocatalysts or protein catalysts. In simple terms, our protein catalysts can accelerate and/or improve yields of chemical reactions. We use our CodeEvolver ® protein engineering technology platform to develop novel enzymes that enable industrial biocatalytic reactions and fermentations. Our technology platform has enabled commercially viable products and processes for the manufacture of pharmaceutical intermediates and active ingredients and fine chemicals.
Our approach to develop commercially viable biocatalytic manufacturing processes begins by conceptually designing the most cost-effective and practical process for a targeted product. We then develop optimized protein catalysts to enable that process design using our CodeEvolver ® protein engineering platform technology. Engineered protein catalyst candidates - many thousands for each protein engineering project - are then rapidly screened and validated in high throughput under

30

relevant manufacturing operating conditions. This approach results in an optimized protein catalyst enabling cost-efficient processes that typically are relatively simple to run in conventional manufacturing equipment. This also allows for the efficient technical transfer of our process to our manufacturing partners.
The successful embodiment of our CodeEvolver ® protein engineering technology platform in commercial manufacturing processes requires well-integrated expertise in a number of technical disciplines. In addition to those directly involved in practicing our CodeEvolver ® protein engineering platform technology, such as molecular biology, enzymology, microbiology, cellular engineering, metabolic engineering, bioinformatics, biochemistry and high throughput analytical chemistry, our process development projects also involve integrated expertise in organic chemistry, chemical process development, chemical engineering, fermentation process development and fermentation engineering. Our integrated, multi-disciplinary approach to biocatalyst and process development is a critical success factor for our company.
We initially commercialized our CodeEvolver ® protein engineering technology platform and products in the pharmaceuticals market, which remains our primary business focus. Our customers, which include several large global pharmaceutical companies, use our technology, products and services in their manufacturing processes and process development.
We have also used the technology to develop protein catalysts for use in the fine chemicals market. The fine chemicals market consists of several large market verticals, including food and food ingredients, animal feed, flavors, fragrances and agricultural chemicals.
More recently, we are also using the CodeEvolver ® protein engineering technology platform to develop early stage, novel biotherapeutic product candidates, both for our customers and for our own business, most notably our lead program for the potential treatment of phenylketonuria ("PKU") disease in humans. PKU is an inherited metabolic disorder in which the enzyme that converts the essential amino acid phenylalanine into tyrosine is deficient.
We have also used our technology to develop an enzyme for customers using next generation sequencing (“NGS”) and polymerase chain reaction (“PCR/qPCR”) for in vitro molecular diagnostic and genomic research applications. Beta testing for the enzyme was initiated in the second quarter of 2017.
Results of Operations Overview
Revenues decreased to $10.3 million for the second quarter of 2017 from $16.0 million in the second quarter of 2016 , primarily due to lower research and development service revenues. Research and development service revenues for the second quarter of 2017 decreased to $3.4 million from $12.1 million in the second quarter of 2016 as the prior year included a $7.5 million milestone and recognition of $2.5 million of deferred revenues upon early completion of the technology transfer of our proprietary CodeEvolver ® protein engineering platform to GlaxoSmithKline ("GSK"). An increase in current quarter research and development service revenues to Tate & Lyle, Merck, and another leading pharmaceutical company partially offset the decrease in research and development revenues. Product sales increased by approximately $3.3 million, or 101%, from the prior year quarter, which was primarily due to higher customer demand for enzymes for both generic and branded products. Revenues from Exela in a revenue sharing arrangement decreased by $0.3 million , or 46% from the prior year quarter.
Product gross margins were 43% in the three months ended June 30, 2017 , compared to 32% in the same period in 2016 due to improved sales mix.
Research and development expenses increased by $1.2 million, or 24% , to $6.3 million for the second quarter of 2017 , compared to the second quarter of 2016 , due primarily to an increase in outside services and an increase in costs associated with higher headcount, which was partially offset by lower amortization of intangibles, which ceased in the fourth quarter of 2016.
Selling, general and administrative expense increased by $0.1 million, or 2% , to $6.5 million for the second quarter of 2017 , compared to the second quarter of 2016 , due primarily to an increase in costs associated with higher headcount, partially offset by a decrease in legal expenses related to intellectual property, lower depreciation and a decrease in outside services.
Net loss for the second quarter of 2017 was $6.3 million, representing a net loss of $0.13 per basic and diluted share. This compares to net income of $2.2 million, representing basic net income of $0.06 per basic share or diluted net income of $0.05 per share for the second quarter of 2016 . The increase in net loss for the second quarter of 2017 over the same period of the prior year is primarily related to recognition of a milestone payment of $7.5 million and deferred revenues of $2.5 million in the prior year quarter, which was partially offset by increased revenue from product sales.

31

Cash and cash equivalents increased by $9.6 million to $28.8 million as of June 30, 2017 compared to $19.2 million as of December 31, 2016 . Net cash used in operating activities was $11.6 million in the six months ended June 30, 2017 compared to net cash provided by operations of $ 0.2 million in the six months ended June 30, 2016 . On April 12, 2017, we completed a public offering of approximately 6.3 million shares of our common stock at an offering price of $4.00 per share resulting in net proceeds to us of approximately $23.3 million. We believe that based on our current level of operations, our existing cash, cash equivalents, and marketable securities will provide adequate funds for ongoing operations, planned capital expenditures and working capital requirements for at least the next 12 months.
In June 2017, we entered into a loan and security agreement that allows us to borrow up to $10.0 million under a term loan, and up to $5.0 million under a revolving credit facility with 80% of certain eligible accounts receivable as a borrowing base (the "Credit Facility"). Obligations under the Credit Facility are secured by a lien on substantially all of our personal property other than our intellectual property. As of June 30, 2017, no amounts were borrowed under the Credit Facility and we were in compliance with the covenants for the Credit Facility. See Note 10, "Commitments and Contingencies--Credit Facility".
GSK Platform Technology Transfer, Collaboration and License Agreement
In July 2014, we entered into a CodeEvolver ® platform technology transfer and license agreement (the "GSK CodeEvolver ® Agreement") with GSK. Pursuant to the terms of the agreement, we granted GSK a non-exclusive license to use the CodeEvolver ® protein engineering technology platform to develop novel enzymes for use in the manufacture of GSK's pharmaceutical and health care products.
We received a $6.0 million up-front license fee upon execution of the GSK CodeEvolver ® Agreement and subsequently a $5.0 million non-creditable, non-refundable milestone payment upon achievement of the first milestone in 2014. In September 2015, we achieved the second milestone and earned milestone revenue of $6.5 million . In the second quarter of 2016, we completed the full transfer of the protein engineering platform technology and earned milestone revenue of $7.5 million . We also have the potential to receive additional back end milestone payments that range from $5.75 million to $38.5 million per project based on GSK’s successful application of the licensed technology. The back end milestone payments are not deemed substantive milestones due to the fact that the achievement of the event underlying the payment predominantly relates to GSK’s performance of future development and commercialization activities.
We are eligible to receive royalties based on net sales, if any, of a limited set of products developed by GSK using the CodeEvolver ® protein engineering technology platform.
The up-front license fee of $6.0 million was recognized ratably over the technology transfer period of three years from July 2014. We recognized all deferred revenue from GSK upon completion of the technology transfer in April 2016. We recognized none of the up-front license fees for the three and six months ended June 30, 2017 , compared to $2.5 million and $3.0 million for the three and six months ended June 30, 2016 , respectively, as research and development revenue.
In September 2016, we recorded our first back end milestone payment based on GSK's successful application of our technology in an existing pharmaceutical product.
Merck Platform Technology Transfer and License Agreement
In August 2015, we entered into a CodeEvolver ® platform technology transfer and license agreement (the "Merck CodeEvolver ® Agreement") with Merck, which allows Merck to use the CodeEvolver ® protein engineering technology platform in the field of human and animal healthcare.

We received a $5.0 million up-front license fee upon execution of the Merck CodeEvolver ® Agreement, which was recognized ratably over the estimated platform technology transfer period of two years. The technology transfer was completed in September 2016 and all remaining deferred revenue was recognized. We recognized none of the up-front license fees for the three and six months ended June 30, 2017 , compared to $0.6 million and $1.3 million for the three and six months ended June 30, 2016 , respectively, as research and development revenue. Additionally, we recognized research and development revenues of $0.9 million and $1.8 million for the three and six months ended June 30, 2017 , respectively, compared to $0.5 million and $0.7 million for the three and six months ended June 30, 2016 , respectively, for various research projects under our collaborative arrangement.
Following the completion of the technology transfer, we may be eligible to receive payments of up to a maximum of $15.0 million for each commercial API that is manufactured by Merck using one or more novel enzymes developed by Merck using the CodeEvolver ® protein engineering technology platform.

Revenues typically fluctuate on a quarterly basis due to the variability in our customers' manufacturing schedules and the timing of our customers' clinical trials. In addition, we have limited internal capacity to manufacture enzymes. As a result, we are dependent upon the performance and capacity of third party manufacturers for the commercial scale manufacturing of the enzymes used in our pharmaceutical and fine chemicals business.
We accept purchase orders for deliveries covering periods from one day up to approximately one year from the date on which the order is placed. However, purchase orders can generally be revised or cancelled by the customer without penalty. Considering these industry practices and our experience, we do not believe the total of customer purchase orders outstanding (backlog) provides meaningful information that can be relied on to predict actual sales for future periods.

33

Revenues were $10.3 million and $18.3 million in the three and six months ended June 30, 2017 , respectively, compared to $16.0 million and $24.0 million for the same periods in 2016 . The decrease in revenues is primarily due to the completion of the technology transfer of our proprietary CodeEvolver ® protein engineering platform to GSK in the prior year, which resulted in prior year revenues of $10.0 million and $10.5 million for the three and six months ended June 30, 2016 , respectively, from recognition of a milestone payment and related deferred revenues. The decrease was partially offset by higher research and development service revenues for Tate & Lyle, Merck and another leading pharmaceutical company. We expect that the research and development revenues for the year will be lower than the prior year as the latter included milestone payments and related deferred revenue recognition from both GSK and Merck from the completion of the transfer of our CodeEvolver ® protein engineering platform to both companies in 2016.
Product sales increased $3.3 million , or 101% , and $5.2 million , or 74% in the three and six months ended June 30, 2017 , respectively, compared to the same periods in 2016 due to higher customer demand for enzymes for both generic and branded products. We expect that the product revenues for the year will be higher than the prior year due to increased demand for our enzymes.
Revenues from the revenue-sharing arrangement with Exela decreased by $0.3 million and $0.6 million during the three and six months ended June 30, 2017 , respectively, compared to the same period in 2016 . This is a result of the expiration of the formulation patent for argatroban in June 2014, allowing for generic competition in the subsequent quarters after expiration of the patent. We expect that the revenue-sharing arrangement revenues may decline in future quarters due to increased competition resulting from the expiration of the third party patent related to the production of argatroban.

Cost of product sales comprises both internal and third-party fixed and variable costs, including materials and supplies, labor, facilities and other overhead costs associated with our product sales.
Product gross margins were 43% and 44% in the three and six months ended June 30, 2017 , respectively, compared to 32% and 33% , respectively, in the corresponding periods in 2016 due to improved sales mix.

Research and Development Expenses
Research and development expenses consist of costs incurred for internal projects as well as partner-funded collaborative research and development activities. These costs primarily consist of (i) employee-related costs, which include salaries and other personnel-related expenses (including stock-based compensation), (ii) various allocable expenses, which include occupancy-related costs, supplies, depreciation of facilities and laboratory equipment and amortization of acquired technologies, and (iii) external costs. Research and development expenses are expensed when incurred.
Research and development expenses increased by $1.2 million, or 24% , during the three months ended June 30, 2017 and $1.4 million , or 13% , during the six months ended June 30, 2017 , compared to the same periods in 2016 primarily due to an increase in outside services and increased costs associated with higher headcount, partially offset by no amortization of intangibles, which were fully amortized by the fourth quarter of 2016.
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist of employee-related costs, which include salaries and other personnel-related expenses (including stock-based compensation), hiring and training costs, consulting and outside services expenses (including audit and legal counsel related costs), marketing costs, building lease costs, and depreciation and amortization expenses.
Selling, general and administrative expenses increased by $0.1 million, or 2% during the three months ended June 30, 2017 compared to the same period in 2016, primarily due to an increase in costs associated with higher headcount, partially offset by a decrease in legal expenses related to intellectual property, lower depreciation expense and lower outside services. For the six months ended June 30, 2017 , selling, general and administrative expenses decreased by $0.1 million , or 1% , compared to the corresponding period in 2016 , primarily due to a decrease in legal expenses related to intellectual property, lower depreciation expenses and lower outside services, partially offset by an increase in costs associated with higher headcount.

Interest income was not material during the three and six months ended June 30, 2017 and 2016 .
The change in other expense for the six months ended June 30, 2017 compared to the same period in 2016 was primarily related to fluctuations in foreign currency.
Provision for income taxes
We recognized income tax benefit of $42,000 and $18,000 for the three and six months ended June 30, 2017 , respectively. We recognized benefit from income tax of $26,000 and $15,000 for the three and six months ended June 30, 2016 , respectively. We continue to recognize a full valuation allowance against our net deferred tax assets as we believe that it is more likely than not that the majority of our deferred tax assets will not be realized.
Net income (loss)
Net loss for the second quarter of 2017 was $6.3 million, representing a net loss of $0.13 per basic and diluted share. This compares to a net income of $2.2 million , representing basic net income of $0.06 per share or diluted net income of $0.05 per share for the second quarter of 2016 . For the six months ended June 30, 2017 , net loss was $13.7 million, representing a net loss of $0.31 per basic and diluted share. This compares to a net loss of $4.7 million , representing basic net loss of $0.12 per basic and diluted share for the six months ended June 30, 2016 The increase in net loss for the three and six months ended June 30, 2017 and over the same period of the prior year is primarily related to the same period of the prior year is primarily related to decrease in research and development revenues which was partially offset by an increase in revenue from product sales net of associated increases in costs of product sales.

35

Liquidity and Capital Resources
Liquidity is the measurement of our ability to meet working capital needs and to fund capital expenditures. Our sources of cash include operations and stock option exercises. For the six months ended June 30, 2017 our most significant cash flow activities consisted of $23.3 million of net proceeds from our underwritten public offering in April 2017, which was completed in April 2017, partially offset by $11.6 million of cash used in operations and $1.6 million taxes paid related to net share settlement of restricted stock awards. We actively manage our cash usage and investment of liquid cash to ensure the maintenance of sufficient funds to meet our working capital needs. The majority of our cash and investments are held in U.S. banks, and our foreign subsidiaries maintain a limited amount of cash in their local banks to cover their short-term operating expenses.
The following tables summarize our cash and cash equivalents and working capital as of June 30, 2017 and December 31, 2016 , as well as our statements of cash flows for the three and six months ended June 30, 2017 and 2016 :

We have historically experienced negative cash flows from operations as we continue to invest in key technology development projects and improvements to our CodeEvolver ® protein engineering technology platform, and expand our business development and collaborations with new customers. Our cash flows from operations will continue to be affected principally by sales and gross margins from product sales and collaborative research and development services provided to customers, as well as our headcount costs, primarily in research and development. Our primary source of cash flows from operating activities is cash receipts from our customers for purchases of products and/or collaborative research and development services. Our largest uses of cash from operating activities are for employee-related expenditures, rent payments, inventory purchases to support our product sales and non-payroll research and development costs.
We are eligible to earn milestone and other contingent payments for the achievement of defined collaboration objectives and certain royalty payments under our collaboration agreements. Our ability to earn these milestone and contingent payments and the timing of achieving these milestones is primarily dependent upon the outcome of our collaborators’ research and development activities and is uncertain at this time.
We believe that based on our current level of operations, our existing cash and cash equivalents will provide adequate funds for ongoing operations, planned capital expenditures and working capital requirements for at least the next 12 months. On May 2, 2017, we received a payment in the low single-digit million dollar range from a customer relating to our March 2017 research and development agreement.
In June 2017, we entered into the Credit Facility, which consists of term debt for loans that allow us to borrow up to $10.0 million and a revolving credit facility that allows us to borrow up to $5.0 million with a certain eligible accounts receivable borrowing base of 80% of eligible accounts receivable. We may draw on the term debt at any time prior to June 30, 2018, subject to customary conditions for funding including, among others, that no event of default exists. Draws on the Credit Facility are secured by a lien on substantially all of our personal property other than our intellectual property. No amounts were drawn down under the credit facility as of June 30, 2017. At June 30, 2017, we were in compliance with the covenants for the Credit Facility. The Credit Facility requires us to maintain compliance with certain financial covenants including attainment of certain lender-approved projections or maintenance of certain minimum cash levels. Restrictive covenants in the Credit Facility restrict the payment of dividends or other distributions. For additional information about our contractual obligations, see Note 10 "Commitments and Contingencies" in the accompanying notes to the unaudited condensed consolidated financial statements. However, we may need additional capital if our current plans and assumptions change. Our need for additional capital will depend on many factors, including the financial success of our business, the spending required to develop and commercialize new and existing products, the effect of any acquisitions of other businesses, technologies or facilities that we may make or develop in the future, our spending on new market opportunities, and the potential costs for the filing, prosecution, enforcement and defense of patent claims, if necessary.

36

As of June 30, 2017, we had cash and cash equivalents of $28.8 million and $15.0 million available to borrow on under the Credit Facility. Our liquidity is dependent upon our cash and cash equivalents, cash flows provided by operating activities and the continued availability of borrowings under the Credit Facility.
If our capital resources are insufficient to meet our capital requirements, and we are unable to enter into or maintain collaborations with partners that are able or willing to fund our development efforts or commercialize any products that we develop or enable, we will have to raise additional funds to continue the development of our technology and products and complete the commercialization of products, if any, resulting from our technologies. If future financings involve the issuance of equity securities, our existing stockholders would suffer dilution. If we raise debt financing, we may be subject to restrictive covenants that limit our ability to conduct our business. We may not be able to raise sufficient additional funds on terms that are favorable to us, if at all. If we fail to raise sufficient funds and fail to generate sufficient revenue to achieve planned gross margins and to control operating costs, our ability to fund our operations, take advantage of strategic opportunities, develop products or technologies, or otherwise respond to competitive pressures could be significantly limited. If this happens, we may be forced to delay or terminate research or development programs or the commercialization of products resulting from our technologies, curtail or cease operations or obtain funds through collaborative and licensing arrangements that may require us to relinquish commercial rights, or grant licenses on terms that are not favorable to us. If adequate funds are not available, we will not be able to successfully execute our business plan or continue our business.
Cash Flows from Operating Activities
Cash used in operating activities was $11.6 million net for the six months ended June 30, 2017 , which resulted from a net loss of $13.7 million for the six months ended June 30, 2017 adjusted for non-cash charges for depreciation and amortization of $0.6 million and stock-based compensation of $3.4 million . Additional cash used from changes in operating assets and liabilities was $1.6 million . Changes in operating assets and liabilities included increases of $1.9 million in accounts receivable, $1.8 million in prepaid expenses primarily for outside services, decreases of $1.4 million decrease in accrued compensation and a $0.4 million in accounts payable. These were partially offset by a $3.9 million increase in deferred revenues.
Cash provided by operating activities was $0.2 million for the six months ended June 30, 2016 , which resulted from a net loss of $4.7 million for the six months ended June 30, 2016 , adjusted for non-cash charges for depreciation and amortization of $2.6 million and stock-based compensation of $2.6 million . Additional cash uses from changes in operating assets and liabilities of $0.3 million , related primarily to a decrease of $3.7 million in deferred revenue, a decrease of $0.5 million in accrued compensation and a decrease of $0.5 million in accounts payable, partially offset by a $4.0 million decrease in accounts receivable and $0.6 million increase in other accrued liabilities.
Cash Flows from Investing Activities
Cash used in investing activities was $0.6 million and $0.4 million for the six months ended June 30, 2017 and 2016 , respectively, primarily related to the purchase of property and equipment.
Cash Flows from Financing Activities
Cash provided by financing activities was $21.7 million for the six months ended June 30, 2017 which represents $23.3 million of net proceeds from the public offering in April 2017, partially offset by $1.6 million for taxes paid related to net share settlement of equity awards. Cash used in operating activities was $0.7 million for the six months ended June 30, 2016 which primarily represented taxes paid related to net share settlement of equity awards.

Contingent commitment
In June 30, 2017, we entered into a credit facility consisting of term loans totaling up to $10.0 million , and advances under a revolving line of credit totaling up to $5.0 million with an accounts receivable borrowing base of 80% of certain eligible accounts receivable. We may draw on the term debt at any time prior to June 30, 2018, subject to customary conditions for funding including, among others, that no event of default exists. The credit facility terminates July 1, 2021 . Term debt loans bear interest through maturity at a variable rate based on the London Interbank Offered Rate plus 3.60% . Advances under the revolving line of credit bear interest at a variable annual rate equal to the greater of (i) 1.00% above the prime rate and (ii) 5.00% . We did not draw from the credit facility at June 30, 2017. For additional information about our credit facility, see Note 10 "Commitments and Contingencies" in the accompanying notes to the unaudited condensed consolidated financial statements.
Off-Balance Sheet Arrangements
As of June 30, 2017 , we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4) of Regulation S-K as promulgated by the SEC.

Critical Accounting Policies and Estimates
The preparation of financial statements in conformity with generally accepted accounting principles requires management to make judgments, estimates and assumptions in the preparation of our consolidated financial statements and accompanying notes. Actual results could differ from those estimates. There have been no material changes to our critical accounting policies or estimates as discussed in our Annual Report on Form 10-K for the year ended December 31, 2016 , filed with the SEC on March 9, 2017 .

ITEM 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market Risk Management
Our cash flows and earnings are subject to fluctuations due to changes in foreign currency exchange rates, interest rates and other factors. These market risk exposures are disclosed in Part I, Item 7A of our Annual Report on Form 10-K for the year ended December 31, 2016 , filed with the SEC on March 9, 2017 .
Interest Rate Sensitivity
In June 30, 2017 , we entered into a credit facility agreement consisting of term loans totaling up to $10.0 million , and advances under a revolving line of credit totaling up to $5.0 million . Draws on the term debt bear interest at a variable rate based on the London Interbank Offered Rate plus 3.60%. Advances under the revolving line of credit bear interest at a variable annual rate equal to the greater of (i) 1.00% above the prime rate and (ii) 5.00%. Increases in these variable interest rates will increase our future interest expense and decrease our results of operations and cash flows. We did not draw from the credit facility at June 30, 2017.

38

Equity Price Risk
As described in Note 5, "Cash Equivalents and Marketable Securities" and Note 6, "Fair Value Measurements" to the condensed consolidated financial statements, we have an investment in common shares of CO 2 Solutions, whose shares are publicly traded in Canada on the TSX Venture Exchange. As of June 30, 2017 , the fair value of our investment in CO 2 Solutions' common stock was $1.3 million , including an unrealized gain of $0.7 million .
This investment is exposed to fluctuations in both the market price of CO 2 Solutions' common shares and changes in the exchange rate between the U.S. dollar and the Canadian dollar. The effect of a 10% adverse change in the market price of CO 2 Solution's common shares as of June 30, 2017 would have been an unrealized loss of approximately $ 0.1 million , recognized as a component of our condensed consolidated statements of comprehensive income (loss). The effect of a 10% adverse change in the exchange rate between the U.S. dollar and the Canadian dollar as of June 30, 2017 would have been an unrealized loss of approximately $0.1 million , recognized as a component of our condensed consolidated statements of comprehensive income (loss).

ITEM 4.
CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures and internal controls that are designed to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and that such information is accumulated and communicated to our management, including our principal executive officer and our principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure.
Our management, including our principal executive officer and our principal financial and accounting officer, evaluated the effectiveness of our disclosure controls and procedures as defined by Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on this review, our principal executive officer and our principal financial and accounting officer concluded that these disclosure controls and procedures were effective as of June 30, 2017 at the reasonable assurance level.
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 paragraph (d) of Exchange Act Rules 13a-15 or 15d-15 that occurred during our last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, even if determined effective and no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives to prevent or detect misstatements. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

PART II. OTHER INFORMATION
ITEM 1.
LEGAL PROCEEDINGS
On February 19, 2016, we filed a complaint against EnzymeWorks, Inc., a California corporation, EnzymeWorks, Inc., a Chinese corporation (collectively with the California corporation, “EnzymeWorks”), and Junhua “Alex” Tao (collectively, with EnzymeWorks, the “Defendants”) in the United States District Court for the Northern District of California. On April 29, 2016, we filed a First Amended Complaint. The First Amended Complaint alleges that the Defendants have engaged in willful patent infringement, trade secret misappropriation, breach of contract, intentional interference with contractual relations, intentional interference with prospective economic relations and statutory and common law unfair competition. We have sought injunctive relief, monetary damages, treble damages, restitution, punitive damages and attorneys’ fees. On May 13, 2016, the Defendants filed a Partial Motion to Dismiss the claims for breach of contract, intentional interference with contractual relations, intentional interference with prospective economic relations, statutory unfair competition, and common law unfair competition in the First Amended Complaint. We opposed the Defendant’s Partial Motion to Dismiss. On August 11, 2016, the judge issued an order that denied the Defendants’ Partial Motion to Dismiss with respect to all five claims and in all relevant parts, and granted the motion with respect to certain underlying arguments. The Defendants filed their Answer on September 1, 2016, stating that the Defendants would not contest infringement of the asserted patents and denying the trade secret claim and other non-patent claims. There are no counterclaims. On September 21, 2016, the parties filed a stipulation in which the Defendants agreed not to contest our construction of certain patent claim terms and vacating deadlines related to the claim construction proceedings. The Court entered the stipulated order on September 26, 2016. On July 19, 2017, Defendants filed a Stipulation with Proposed Order seeking leave to file Defendants’ First Amended Answer to add an affirmative defense of “competition privilege.” The Court entered the Order granting leave for Defendants to file the First Amended Answer on July 24, 2017. On July 31, 2017, the parties filed a stipulation acknowledging that EnzymeWorks had not denied or disputed its infringement of each of Codexis’ ten asserted patents, or the validity of those patents. Based on this stipulation, on August 8, 2017, the Court entered an order granting Codexis summary judgment on its claims of patent infringement against EnzymeWorks. Additional issues remain to be resolved, including Tao’s individual liability for the infringement, Codexis’ claims that the infringement was willful, the amount of damages to be awarded to Codexis, and the trade secret and other non-patent claims. The case is currently in fact discovery, which is scheduled to close on August 30, 2017. We are unable to determine when this litigation will be resolved or its ultimate outcome.
Other than our litigation against the Defendants, we are not currently a party to any material litigation or other material legal proceedings.

ITEM 1A.
RISK FACTORS
We have included in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016, a description of certain risks and uncertainties that could affect our business, future performance or financial condition (the “Risk Factors”). Except as set forth below, there are no material changes from the disclosure provided in the Form 10-K for the year ended December 31, 2016 with respect to the Risk Factors. Investors should consider the Risk Factors prior to making an investment decision with respect to our stock.
If we are unable to comply with the terms of our credit facility, our business and financial condition would be materially and adversely affected.
On June 30, 2017 we entered into a credit facility ("Credit Facility") financing arrangement secured by a lien on substantially all of our personal property other than our intellectual property. Although we have no loans or draws under the Credit Facility as of the date of this report, the Credit Facility includes affirmative and negative covenants including, among others, covenants requiring us to achieve consolidated product revenues at minimum levels and restricting our ability to transfer collateral, incur additional indebtedness, engage in mergers or acquisitions, pay dividends or make other distributions, make investments, create liens and sell assets. The Credit Facility also includes events of default including, among other things, our failure to pay any amounts due under the Credit Facility, a breach of covenants under the Credit Facility, our insolvency, a material adverse change, the occurrence of any default under certain other indebtedness in an amount greater than $250,000 and a final judgment against us in an amount greater than $250,000. If an event of default occurs, it could cause our obligations to become immediately due and payable and our lender would be entitled to foreclose against the collateral securing the indebtedness, including our cash. If our indebtedness were to be accelerated, we may be unable to repay such debt and, therefore, such acceleration could materially and adversely affect our business and financial condition. For more information

regarding our compliance with our financial covenants, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Debt service obligation may place us at a competitive disadvantage in our industry.
Draws under the Credit Facility would create debt service obligations for us. Although we have not drawn on the Credit Facility to date, any future draws under the Credit Facility and the related debt service requirements could adversely affect our ability to operate our business and may limit our ability to take advantage of potential business opportunities. For example, the Credit Facility presents the following risks, certain of which apply regardless of whether we draw on the Credit Facility:
•
we may be required to use a portion of our cash flow from operations to make debt service payments, thereby reducing the availability of our cash flow to fund working capital, capital expenditures, product development efforts, research and development, and other general corporate requirements;
•
our interest expense could increase if prevailing interest rates increase, because a portion of draws which could be made under the Credit Facility bear interest at floating rates;
•
the Credit Facility could reduce our flexibility to adjust to changing business conditions or obtain additional financing to fund working capital, capital expenditures, product development efforts, research and development, and other general corporate requirements; and
•
restrictive covenants in our Credit Facility, which apply regardless of whether we draw down under the facility, limit our ability to, among other things, transfer collateral, incur additional indebtedness, engage in mergers or acquisitions, pay dividends or make other distributions, make investments, create liens and sell assets.

ITEM 2.
UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
Effective June 30, 2017, we entered into a credit facility consisting of a term debt note for loans totaling up to $10.0 million, and advances under a revolving line of credit totaling up to $5.0 million. Covenants in the credit facility limit our ability to pay dividends or make other distributions. For additional information see Note 10 "Commitments and Contingencies" in the accompanying notes to the unaudited condensed consolidated financial statements.
