Arcadia Biosciences, Inc.

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1. Description of Business and Basis of Presentation

Organization

Arcadia Biosciences, Inc. (the “Company”) was incorporated in Arizona in 2002 and maintains its headquarters in Davis, California, with additional facilities in Phoenix, Arizona, and American Falls, Idaho. The Company was reincorporated in Delaware in March 2015.

We are a consumer-driven, agricultural food ingredient company and proven leader in agricultural innovation to improve the quality and nutritional content of crops. We aim to create value across the agricultural production and supply chain beginning with enhanced crop productivity for farmers and ultimately delivering accelerated innovation in nutritional quality consumer foods.  We use state of the art gene-editing technology and advanced breeding techniques to naturally enhance the nutritional quality of grains and oilseeds to address the rapidly evolving trends in consumer health and nutrition. In addition, we have developed high value crop productivity traits designed to enhance farm economics.  

In February 2012, the Company formed Verdeca LLC (“Verdeca,” see Note 5), which is jointly owned with Bioceres Crop Solutions Corp. (“Bioceres”), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development cooperative. Verdeca, which is consolidated by the Company, was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies.

Reverse Stock Split

In January 2018, the Company’s board of directors and its shareholders approved a reverse split of 1:20 on the Company’s issued and outstanding common stock which became effective on January 23, 2018. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the condensed consolidated financial statement have been retroactively adjusted to reflect the reverse stock split for all periods presented. The reverse stock split did not change the total number of authorized shares of common stock which remained at one hundred and fifty million shares.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and Verdeca in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities (“VIEs”). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Verdeca, which is a VIE. The Company evaluates its relationships with the VIEs upon the occurrence of certain significant events that affect the design, structure or other factors pertinent to the primary beneficiary determination. Interim results are not necessarily indicative of results for any other interim period or for the full fiscal year. The information included in these condensed consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included herein and Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K, filed with the SEC on April 1, 2019.

Liquidity, Capital Resources, and Going Concern

As of March 31, 2019, the Company had an accumulated deficit of $191.0 million, cash and cash equivalents of $10.4 million and short-term investments of $7.4 million. For the three months ended March 31, 2019 and the twelve months ended December 31, 2018, the Company had net losses of $12.6 and $13.5 million, and net cash used in operations of $4.0 million and $13.6 million, respectively. The Company believes that its existing cash, cash equivalents and investments will be insufficient to meet its anticipated cash requirements for at least through March 2020, and thus raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

5

The Company may seek to raise additional funds through debt or equity financings. The Company may also consider entering into additional partner arrangements. The sale of additional equity would result in dilution to the Company’s stockholders. The incurrence of debt would result in debt service obligations, and the instruments governing such debt could provide for additional operating and financing covenants that would restrict operations. If the Company does require additional funds and is unable to secure adequate additional funding at terms agreeable to the Company, the Company may be forced to reduce spending, extend payment terms with suppliers, liquidate assets, or suspend or curtail planned development programs. Any of these actions could materially harm the business, results of operations and financial condition. 

2. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in U.S. GAAP. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, which defers the effective date of ASU No. 2014-09 by one year allowing early adoption as of the original effective date January 1, 2017. The standard was adopted on January 1, 2018.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Based on the new standard, lessees recognize lease assets and lease liabilities for leases classified as operating leases under previous GAAP and disclose qualitative and quantitative information about leasing arrangements with terms longer than 12 months. The adoption required recording right-of-use assets and corresponding lease obligation liabilities for the current operating leases. The Company has adopted ASU No. 2016-02 on January 1, 2019. See Note 7.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of ASU No. 2016-13 on its consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments address cash flow issues such as debt prepayment or debt extinguishment costs and zero-coupon debt instruments. The amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The amendments are to be applied using a retrospective transition method to each period presented. If it is impractical to retrospectively apply, it can be applied prospectively as of the earliest date practicable. The Company adopted ASU No. 2016-15 on January 1, 2019 with no material impact to the consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13 Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments affect any entity required to make disclosures about recurring or nonrecurring fair value measurements. The amendments are effective for all entities for fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of the adoption of ASU No. 2018-13 on its consolidated financial statements.

4. Investments and Fair Value of Financial Instruments

Available-for-Sale Investments

The Company classified short-term investments as “available-for-sale.” These short-term investments are free of trading restrictions. The investments are carried at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses, net of taxes, are included in accumulated other comprehensive loss, which is reflected as a separate component of stockholder’s equity in the Consolidated Balance Sheets. Gains and losses are recognized when realized in the Consolidated Statements of Operations and Comprehensive Loss.

The following tables summarize the amortized cost and fair value of the available-for-sale investment securities portfolio at March 31, 2019 and December 31, 2018, and the corresponding amounts of unrealized gains and losses recognized in accumulated other comprehensive income:

(Dollars in thousands)	Amortized Cost		Unrealized Gains		Unrealized Losses		Estimated Fair Value

U.S. government securities		1,198		—		—		1,198
Total Assets at Fair Value	$	21,072	$	—	$	—	$	21,072

The Company did not have any investment categories that were in a continuous unrealized loss position for more than three months as of March 31, 2019. Unrealized gains and losses amounts would be included in accumulated other comprehensive income or loss; however, none were reported during the periods presented.

As of March 31, 2019, for fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company anticipates that it will recover the entire amortized cost basis of such fixed income securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three months ended March 31, 2019.

Fair Value Measurement

Fair value accounting is applied for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the condensed consolidated financial statements on a recurring basis. Assets and liabilities recorded at fair value in the condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities, are as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date.

• Level 2 inputs are observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 inputs are unobservable inputs for the asset or liability.

The following table sets forth the fair value of the Company’s financial assets as of March 31, 2019 and December 31, 2018:  

	Fair Value Measurements at March 31, 2019

The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2019 or 2018. The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, short-term investments and accounts payable and accrued liabilities. For accounts receivable, accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of March 31, 2019 and December 31, 2018 were considered representative of their fair values due to their short term to maturity or repayment. Cash equivalents are carried at cost, which approximates their fair value.

8

The Company’s Level 3 liabilities, which were measured and recorded on a recurring basis, consist of liabilities related to the March 2018 Purchase Agreement and the June 2018 Offering described in Note 8. The following table sets forth the establishment of these liabilities, as well as a summary of the changes in the fair value (in thousands):

	(Level 3)
(Dollars in thousands)	Common Stock Warrant Liability - Purchase Agreement		Common Stock Warrant Liability - June Offering		Total
Balance as of December 31, 2018	$	2,354	$	2,729	$	5,083
Change in fair value		3,970		4,525		8,495
Balance as of March 31, 2019	$	6,324	$	7,254	$	13,578

In determining the fair value, the Company uses various valuation approaches within the fair value measurement framework. The valuation methodologies used for the Company’s instruments measured at fair value and their classification in the valuation hierarchy are summarized below:

• Money market funds, treasury bills, and U.S. government securities – Investments in money market funds, treasury bills, and U.S. government securities are classified within Level 1.  At March 31, 2019 and December 31, 2018 these investments were included on the consolidated balance sheets in cash and cash equivalents and short-term investments.

• Commercial paper, corporate securities – Investments in commercial paper and corporate securities are classified within Level 2. At March 31, 2019 these investments were included on the consolidated balance sheets in cash and cash equivalents and short-term investments. At December 31, 2018, commercial paper was included on the consolidated balance sheets in short-term investments.

• Purchase Agreement common stock warrant liability – The Company has outstanding warrants to purchase 1,282,832 shares of common stock that it issued to certain accredited investors and its placement agent on March 22, 2018 (as described in Note 8). The common stock warrants were classified as a liability within Level 3 based on the instrument’s adjustment features and a contingent cash payment feature. The estimated fair value of the common stock warrant liability was remeasured at March 31, 2019 utilizing a Black Scholes Merton Model with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss.

• June 2018 Offering common stock warrant liability – The Company has outstanding warrants to purchase 1,461,962 shares of common stock that it issued to certain accredited investors on June 14, 2018 (as described in Note 8). The common stock warrants are classified as a liability within Level 3 due to a contingent cash payment feature.  The estimated fair value of the common stock warrant liability was remeasured at March 31, 2019 utilizing a Black Scholes Merton Model with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss.

5. Variable Interest Entity

In February 2012, the Company formed Verdeca LLC (“Verdeca”), which is equally owned with Bioceres Crop Solutions Corp. (“Bioceres”), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development cooperative owned by approximately 300 shareholders, including some of South America’s largest soybean growers. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies.

The Company determined that a de facto agency relationship between the Company and Bioceres exists. The Company considers qualitative factors in assessing the primary beneficiary which include understanding the purpose and design of the VIE, associated risks that the VIE creates, activities that could be directed by the Company, and the expected relative impact of those activities on the economic performance of the VIE. Based on an evaluation of these factors, the Company concluded that it is the primary beneficiary of Verdeca.

Both the Company and Bioceres incur expenses in support of specific activities, as agreed upon by joint work plans, which apply fair market value to each partner’s activities. Unequal contributions of services are equalized by the partners through cash payments. Verdeca is not the primary obligor for these activities performed by the Company or Bioceres. Under the terms of the joint development agreement, the Company has incurred direct expenses and allocated overhead in the amounts of $243,000 and $286,000, for the three months ended March 31, 2019 and 2018, respectively.

6. Collaborative Arrangements

In August 2017, the Company entered into a collaborative arrangement for the research, development and commercialization of an improved wheat quality trait in North America.  This collaborative arrangement is a contractual agreement with Dow AgroSciences, LLC (“Dow”) and involves a joint operating activity where both Arcadia and Dow are active participants in the activities of the collaboration. Arcadia and Dow participate in the research and development, and Arcadia has the primary responsibility for the intellectual property strategy while Dow will generally lead the marketing and commercialization efforts.  Both parties are exposed to significant risks and rewards of the collaboration and the agreement includes both cost sharing and profit sharing. The activities are performed with no guarantee of either technological or commercial success.  

The Company accounts for research and development (“R&D”) costs in accordance ASC 730, Research and Development, which states R&D costs must be charged to expense as incurred. Accordingly, internal R&D costs are expensed as incurred. Third-party R&D costs are expensed when the contracted work has been performed or as milestone results are achieved.

7. Leases

As of March 31, 2019, the Company leases office space in Davis, CA and Phoenix, AZ, as well as additional buildings, land and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis. The Company subleases a portion of the Davis office lease and Greenhouse to third parties. The Company does not currently have any finance leases or material leases that have not yet commenced but that create significant rights and obligations for the Company.

Some leases (the warehouse, greenhouse and the Phoenix copier) include one or more options to renew, with renewal terms that can extend the lease term from one to six years. The exercise of lease renewal options is at the Company’s sole discretion.

The Company’s lease agreements do not contain any material variable lease payments, material residual value guarantees or material restrictive covenants. Leases consisted of the following (in thousands):

8. Private Placement and Registered Direct Offering  

Private Placement

On March 22, 2018, the Company issued 300,752 shares of its common stock (“Common Stock”) and warrants to purchase up to 300,752 shares of Common Stock with an initial exercise price equal to $45.75 (the “March 2018 Warrants”), in a private placement (the “March 2018 Private Placement”) in accordance with a securities purchase agreement (the “the March 2018 Purchase Agreement”) entered into with certain institutional and accredited investors (collectively, the “Purchasers”) on March 19, 2018. The number of shares of Common Stock, the number and exercise price of the March 2018 Warrants issued to the Purchasers were subject to adjustments as provided in the March 2018 Purchase Agreement.  The March 2018 Warrants are immediately exercisable, subject to certain ownership limitations, and expire five years after the date of issuance.

Following the adjustments as provided in the March 2018 Purchase Agreement, the number of shares issued to the Purchasers was 1,201,636, the total number of shares issuable upon exercise of the March 2018 Warrants was 1,282,832 and the per share exercise price of the March 2018 Warrants was $10.7258. These condensed consolidated financial statements reflect these additional issuances.

The aggregate net proceeds received by the Company from the March 2018 Private Placement was $8.7 million, consisting of gross proceeds of $10.0 million less offering costs of $1.3 million. The Company entered into the March 2018 Private Placement to secure additional capital to strengthen its cash resources required to launch its new health and nutrition ingredient product commercialization and production scale-up plans, as well as to continue the deregulation and commercialization of its stress tolerant HB4 soybean trait. More specifically, net proceeds have been and will continue to be used for working capital to fund the continued introgression of quality ingredient traits into elite germ plasm, additional seed bulk-up, increased planting acreage, consumer brand development and a number of other pre-commercialization and commercialization activities.

The adjustment feature for the Common Stock and the March 2018 Warrants were determined to be liabilities based on each instrument’s adjustment features and the contingent cash payment feature of the common stock warrants. The liabilities were accounted for at their respective fair values at inception using a Monte Carlo simulation model with the following assumptions: volatility of 100 percent, stock price of $32.52 and risk-free rate of 2.63%. At inception, the fair values of the Common Stock adjustment feature and the March 2018 Warrant liabilities were $3.8 million and $10.2 million, respectively. As the combined value of the liabilities exceeded the $10.0 million of proceeds, no value was assigned to the Common Stock issued and an initial loss of $4.0 million was recognized. The liabilities are marked-to-market and were valued at $15.9 million at March 31, 2018, resulting in an additional loss of $1.9 million in the first quarter of 2018.

In May 2018, following the March 2018 Private Placement’s final adjustment, the terms of the March 2018 Warrants and the number of Common Stock shares issuable in the March 2018 Private Placement became known and fixed. As a result, the common stock adjustment feature liability was marked-to-market and valued at $8.4 million at May 7, 2018, resulting in an additional loss of $2.4 million recognized in the second quarter of 2018. The Company subsequently reclassified the Common Stock adjustment feature liability’s balance of $8.4 million to stockholders’ equity. The March 2018 Warrant liability was marked-to-market and valued at $6.3 million at March 31, 2019, resulting in expense of $4.0 million recognized in the first quarter of 2019 as the contingent cash payment feature was still in effect.

Offering Costs

In connection with the March 2018 Private Placement, the Company paid to a placement agent an aggregate fee equal to $850,000.  The Company also granted warrants to purchase a total of 15,038 shares of common stock (the “March 2018 Placement Agent Warrants”) that have an exercise price per share equal to $41.5625 and a term of five years. The March 2018 Placement Agent Warrants were issued for services performed by the placement agent as part of the March 2018 Private Placement and were treated as offering costs.  The value of the March 2018 Placement Agent Warrants was determined to be $526,000 using the Black-Scholes Merton Model (the “Black-Scholes Model”) with input assumptions including the Company’s stock price, expected life of the warrants, stock price volatility determined from the Company’s historical stock prices and the volatility of a peer group, and the risk-free interest rate for the term of the warrants. The Company incurred additional offering costs totaling $458,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the March 2018 Private Placement. The offering costs, inclusive of the March 2018 Placement Agent Warrants, totaled $1.8 million, all of which was expensed in 2018.

Registered Direct Offering

On May 11, 2018, the Company filed a shelf Registration Statement on Form S-3 with the SEC which was declared effective on June 8, 2018. This registration statement allows the Company to sell any combination of Common Stock, preferred stock, warrants and units consisting of such securities in one or more offerings from time to time having an aggregate initial offering price of $50 million.

On June 11, 2018, the Company entered into agreements with several institutional and accredited investors (the “June 2018 Purchase Agreement”) for the purchase of 1,392,345 shares of its common stock at a purchase price of $9.93 per share for gross proceeds of $13.8 million (the “June 2018 Offering”). The 1,392,345 shares of Common Stock sold in the June 2018 Offering were issued pursuant to a prospectus, dated June 8, 2018, and a prospectus supplement dated June 11, 2018, in connection with a takedown from the Company’s shelf Registration Statement on Form S-3. The June 2018 Offering closed on June 14, 2018.

Additionally, in a concurrent private placement (the “June 2018 Private Placement”), the Company issued to the investors unregistered warrants to purchase up to 1,392,345 shares of Common Stock at a purchase price per warrant of $0.125, for gross proceeds of $174,000 (the “June 2018 Warrants”). The June 2018 Warrants, and the shares of Common Stock underlying the June 2018 warrants, have not been registered with the SEC and have an exercise price of $9.94 per share. Subject to certain ownership limitations, the June 2018 Warrants are exercisable upon issuance and expire five and one-half years after the date of issuance.

The aggregate net proceeds received by the Company for the June 2018 Offering were $12.8 million, consisting of gross proceeds of $14.0 million less offering costs of $1.2 million. The Company has used and intends to continue to use the net proceeds from this offering for general corporate purposes, including, but not limited to, scale-up of its GoodWheat^TM Resistant Starch wheat production, early commercialization activities, continued research and development activities and for general and administrative expenses.

The June 2018 Warrants were determined to be a liability as they have a contingent cash payment feature. The June 2018 Warrants were accounted for at their fair value at inception using the Black Scholes Model with the following assumptions: volatility of 108 percent, stock price of $8.20 and risk-free rate of 2.83%.  At inception, the fair value of the June 2018 Warrants was $9.0 million and the remaining $5.0 million of the $14.0 million of proceeds was allocated to the Common Stock using the residual method and accounted for as stockholders’ equity. The June 2018 Warrants were marked-to-market and valued at $7.3 million at March 31, 2019, resulting in expense of $4.5 million recognized in the first quarter of 2019.

Offering Costs

In connection with the June 2018 Offering, the Company paid to a placement agent an aggregate fee equal to $980,000.  The Company also granted warrants to purchase a total of 69,617 shares of common stock (“June 2018 Placement Agent Warrants”) that have an exercise price per share equal to $12.568 and a term of five years. The June 2018 Placement Agent Warrants were issued for services performed by the placement agent as part of the June 2018 Offering and were treated as offering costs. The value of the June 2018 Placement Agent Warrants was determined to be $427,000 using the Black-Scholes Model with input assumptions including the Company’s stock price, expected life of the warrants, stock price volatility determined from the Company’s historical stock prices and the volatility of a peer group, and the risk-free interest rate for the term of the warrants. The Company incurred additional offering costs totaling $226,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the June 2018 Offering. The offering costs, inclusive of the June 2018 Placement Agent Warrants, totaled $1.6 million and allocated to the June 2018 Warrants and the Common Stock using their relative fair values. A total of $721,000 was allocated to the June 2018 Warrants which was expensed in 2018. The remaining $912,000 was allocated to the common stock and offset to additional paid in capital.

9. Stock-Based Compensation and Warrants

Stock Incentive Plans

The Company has two equity incentive plans: the 2006 Stock Plan (“2006 Plan”) and the 2015 Omnibus Equity Incentive Plan (“2015 Plan”).

In 2006, the Company adopted the 2006 Plan, which provided for the granting of stock options to executives, employees, and other service providers under terms and provisions established by the Board of Directors. The Company granted non-statutory stock options (“NSOs”) under the 2006 Plan until May 2015, when the 2006 Plan was terminated as to future awards. The 2006 Plan continues to govern the terms of options that remain outstanding and were issued under the 2006 Plan. The 2015 Plan became effective in May 2015 and all shares that were reserved, but not issued, under the 2006 Plan were assumed by the 2015 Plan. Upon effectiveness, the 2015 Plan had 154,387 shares of common stock reserved for future issuance, which included 10,637 shares under the 2006 Plan that were transferred to and assumed by the 2015 Plan. The 2015 Plan provides for automatic annual increases in shares

12

available for grant. In addition, shares subject to awards under the 2006 Plan that are forfeited or canceled will be added to the 2015 Plan. The 2015 Plan provides for the grant of incentive stock options (“ISOs”), NSOs, restricted stock awards, stock units, stock appreciation rights, and other forms of equity compensation, all of which may be granted to employees, officers, non-employee directors, and consultants. The ISOs and NSOs will be granted at a price per share not less than the fair value at the date of grant. Options granted generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly thereafter; however, the options granted in the third quarter of 2018 vest over a two-year period, vesting monthly on a pro-rated basis. Options granted, once vested, are generally exercisable for up to 10 years after grant.

As of March 31, 2019, a total of 538,953 shares of common stock were reserved for issuance under the 2015 Plan, of which 65,872 shares of common stock are available for future grant. As of March 31, 2019, a total of 62,162 and 473,081 options are outstanding under the 2006 and 2015 Plans, respectively.

A summary of activity under the stock incentive plans is as follows (in thousands, except share data and price per share):

	Shares Subject to Outstanding Options			Weighted- Average Exercise Price Per Share		Aggregate Intrinsic Value
Outstanding — Balance at December 31, 2018		530,044		$	35.53	$	—

Exercisable —March 31, 2019		231,086		$	60.40	$	182

As of March 31, 2019, there was $0.9 million of unrecognized compensation cost related to unvested stock-based compensation grants that will be recognized over the weighted-average remaining recognition period of 1.9 years.

The fair value of stock option awards to executives and other service providers was estimated at the date of grant using the Black-Scholes Model with the following weighted-average assumption. There were 7,500 and 10,000 options granted during the three months ended March 31, 2019 and 2018, respectively.

Employee Stock Purchase Plan

The Company’s 2015 Employee Stock Purchase Plan (“ESPP”) became effective on May 14, 2015. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% of their eligible compensation through payroll deductions, subject to any plan limitations.   The ESPP provides for six-month offering periods, and at the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period. As of March 31, 2019, the number of shares of common stock reserved for future issuance under the ESPP is 108,864. The ESPP provides for automatic annual increases in the shares available for purchase beginning on January 1, 2016. As of March 31, 2019, 9,353 shares had been issued under the ESPP. The Company recorded $4,300 and $1,200 of compensation expense for the three months ended March 31, 2019 and 2018, respectively.

Warrants

As of March 2019, the Company has 2,821,144 common stock warrants outstanding with a weighted average exercise price of $18.15. The expiration of the warrants ranges from April 2019 to June 2023.

13

On December 2013, the Company issued warrants to Mahyco International to purchase 3,784 shares of common stock, exercisable as of the issuance date, at an exercise price of $330.40 per share. These warrants expired on December 11, 2018.

In connection with the Series D preferred stock financing in the first half of 2014, the Company issued warrants, exercisable as of the issuance date, to the Series D preferred stock investors to purchase an aggregate of 61,397 shares of common stock at an exercise price of $363.20 per share and to the placement agents to purchase 1,674 shares of common stock at $268.80. Of the 61,397 warrants issued to the investors, 1,759 expired on March 28, 2019 and the remaining 59,638 expire in the second quarter of 2019, along with those issued to the placement agents.

As of March 2019, 1,297,870 common stock warrants are outstanding that were issued in the March 2018 Private Placement. The final exercise price for these warrants is $10.7258 as adjusted in accordance with the March 2018 Purchase Agreement’s adjustment provisions.  See Note 8.

As of March 2019, 1,461,962 common stock warrants are outstanding in accordance with the June 2018 Offering. Of the total, 1,392,345 shares have a purchase price of $9.94 and the remaining 69,617 common stock warrants have an exercise price of $12.568. See Note 8.

10. Income Taxes

Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items that are recorded in the interim period. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is obtained, additional information becomes known, or as the tax environment changes.

The interim financial statement provision for income taxes expense is different from the amounts computed by applying the United States federal statutory income tax rate of 21%. The Company’s effective tax rate was -0.1% and -0.2% for the three months ended March 31, 2019 and 2018, respectively. The difference between the effective tax rate and the federal statutory rate of 21% was primarily due to the full valuation allowance recorded on the Company’s net deferred tax assets and foreign withholding taxes.

The Company may have experienced an ownership change under IRC Section 382 as a result of the common shares issued in connection with the March 2018 Purchase Agreement or in the June 2018 Offering. Such an ownership change may limit the Company’s ability to utilize its net operating loss carryforwards prior to expiration. Given the full valuation allowance, such a limitation would not impact the deferred tax asset balance as currently recorded.

As of March 31, 2019, there have been no material changes to the Company’s uncertain tax positions.

11. Contingent Liability Related to the Anawah Acquisition

On June 15, 2005, the Company completed its agreement and plan of merger and reorganization with Anawah, Inc. (“Anawah”), to purchase the food and agricultural research company through a non-cash stock purchase. Pursuant to the merger with Anawah, and in accordance with the ASC 805 - Business Combinations, the Company incurred a contingent liability not to exceed $5.0 million. This liability represents amounts to be paid to Anawah’s previous stockholders for cash collected on revenue recognized by the Company upon commercial sale of certain specific products developed using technology acquired in the purchase. As of December 31, 2010, the Company ceased activities relating to three of the six Anawah product programs, thus, the contingent liability was reduced to $3.0 million. During the third quarter of 2016, one of the programs previously accrued for was abandoned and another program previously abandoned was reactivated. As of March 31, 2019, the Company continues to pursue three development programs using this technology and believes that the contingent liability is probable. As a result, $3.0 million remains on the Condensed Consolidated Balance Sheet as an other noncurrent liability.

12. Net Loss per Share

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period and excludes any dilutive effects of stock-based awards and warrants. Diluted net loss per share is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options and warrants. As of March 31, 2019, all potentially dilutive common shares were determined to be anti-dilutive after evaluation.

14

Securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in shares):

	Three Months Ended March 31,
		2019	2018
Options to purchase common stock		535,243	252,554
Warrants to purchase common stock		2,821,144	382,645
Total		3,356,387	635,199

13. Related-Party Transactions

The Company’s related parties include Moral Compass Corporation (“MCC”) and the John Sperling Foundation (“JSF”).  The rights to the intellectual property owned by Blue Horse Labs, Inc. (“BHL”) were assigned to its sole shareholder, the John Sperling Revocable Trust (“JSRT”) due to BHL’s dissolution and then subsequently to the JSF. The JSF is deemed a related party of the Company because MCC, the Company’s largest stockholder, and the JSF share common officers and directors.

JSF receives a single digit royalty from the Company when revenue has been collected on product sales or for license payments from third parties that involve certain intellectual property developed under research funding originally from BHL. Royalty fees due to JSF were $12,000 and $29,000 as of March 31, 2019 and December 31, 2018, respectively, and are included in the Condensed Consolidated Balance Sheets as amounts due to related parties.

14. Subsequent Events

The Company has reviewed and evaluated subsequent events through May 8, 2019, the date the condensed consolidated financial statements were available to be issued.

Overview

We are a consumer-driven, agricultural food ingredient company. We aim to create value across the agricultural production and supply chain beginning with enhanced crop productivity for farmers and ultimately delivering accelerated innovation in nutritional quality foods to consumers.  We use state of the art gene-editing technology and advanced breeding techniques to naturally enhance the nutritional quality of grains and oilseeds to address the rapidly evolving trends in consumer health and nutrition. In addition, we have developed a broad pipeline of high value crop productivity traits designed to enhance farm economics.  

Consumers are demanding food companies provide healthier, high quality foods, naturally and sustainably produced with greater ingredient simplicity and transparency. Now, more than ever, consumers are paying premium pricing to satisfy their dietary health requirements, such as higher fiber and lower gluten in grains, healthier oils and fewer processed ingredients. Consumer food companies recognize this shift but cannot rely upon the legacy ag-supply chain and traditional crop breeding techniques to meet these demands. Conventional and transgenic breeding processes can take between nine and 13 years to bring new food varieties or quality traits to market, causing consumer food companies to search for alternative means to satisfy the evolving customer demands. The need for rapid product differentiation at the consumer level has opened up a premium food market opportunity that is becoming one of the fastest growing segments in the food industry.  

To address this large and growing demand, we are building on our industry leading scientific expertise and advanced plant breeding and transformation technologies developed over the past 15 years, to directly edit the plant genome without introducing foreign DNA, to produce nutrient-dense crops for use in the major foods we eat. By employing gene editing technology and our TILLING platform, we believe we can reduce the time to market for novel ingredient traits by half, thereby providing consumer food companies a steady and reliable source of cost effective, healthy natural food options.

In 2018, we launched our GoodWheat™ brand, a non-genetically modified (non-GM) portfolio of wheat products that enables food manufacturers to differentiate their consumer-facing brands. The brand launch is a key element of the company’s go-to-market strategy to achieve greater value for its innovations by participating in downstream consumer revenue opportunities. Arcadia designed the brand to make an immediate connection with consumers that products made with GoodWheat™ meet their demands for healthier wheat options that also taste great. The GoodWheat™ brand encompasses Arcadia’s current and future non-GM wheat portfolio of high fiber Resistant Starch (RS) and Reduced Gluten wheat varieties, as well as future wheat innovations. In October 2018, the U.S. Patent and Trademark Office granted Arcadia a patent for extended shelf life wheat, the newest trait in our non-genetically modified (non-GM) GoodWheat™ portfolio. This new trait was designed to promote whole wheat consumption by improving the shelf life and taste of whole grain wheat products.

16

We expect to market GoodWheat™ products in the latter part of this year. Increased fiber consumption is well recognized as a way to improve gut health and to control excessive weight gain. Concurrently, we are developing three additional wheat varieties, a reduced gluten wheat, an extended shelf life wheat and a superior yielding wheat. In the American diet, each day more than 500 calories come from wheat products, 25 percent of the FDA’s recommended daily caloric intake for a woman and 20 percent for a man. We believe these varieties have broad application in the global wheat market which is estimated by the USDA (US Department of Agriculture) to be 758 million metric tons for the 2017/2018 production year, which roughly equates to $208 billion farm gate value (i.e. market value net of selling costs).

In years to come, we expect to achieve enhanced nutritional characteristics within a number of other broad acre crops using advanced breeding and gene-editing techniques. Targets include but are not limited to higher fiber, longer shelf life and enhanced protein in crops other than wheat.      

Another aspect of our business is improving farmer productivity through the development of more robust crop varieties, by developing specific crop traits designed to counteract the detrimental impact of environmental stresses on harvest yields. Traditional genetic modification (GM) trait development has concentrated on crops where the combination of large acreage and high input costs (such as chemical costs for pest and weed control) create significant economic value for herbicidal or insecticidal traits. However, far more deleterious to crop yields are abiotic stresses, such as drought, heat, nutrient deficiency, water scarcity, and soil salinity, and remains largely unpenetrated by the GM seed industry today. For example, industry estimates indicate greater than 80 percent of wheat yield loss and 65 percent of corn yield loss globally are lost due to abiotic factors. These stresses are prevalent in most agricultural environments with varying degrees of severity and often have material consequences on crop production, quality, and farmers’ incomes.

We devoted much of our early research to building a comprehensive array of abiotic stress traits. Furthermore, through out-licensing arrangements with our commercialization partners, many of our traits have been bred into several global crops, including rice, wheat, and soybeans, and we have demonstrated significant yield improvements in multiple years of field testing. However, due to the global variability in acceptance of GM traits from one territory to the next, the commercial timing and ultimate value of these innovations is difficult to predict.

Regardless of the timing and degree of commercial success of our historical GM traits, the technical achievements they represent has established the company as a world-class plant transformation organization.  

Balancing our near-term revenue goals with long-term value capture, we will continue to provide active support to our commercial partners working to advance our high value traits through development and deregulation for commercialization.

While we seek patent protection on our technologies and traits, we have structured our commercial agreements so that we receive our percentage of additional commercial value whether or not patent protection is in effect at any particular time or place. Nearly all of our agreements provide access to our traits, and our right to receive a share of commercial value, continue for a set number of years after products containing our traits are commercialized. While the exclusive rights afforded by patents may enable our commercial partners to realize greater commercial value attributable to our traits, our right to receive a portion of that increased commercial value is not dependent on the existence of patent rights in a particular geography.

Our commercial strategy is to migrate forward in the ag-food supply chain from the farmer and seed company to the consumer food company. Due to our early stage focus on the development of abiotic stress traits, we have historically been commercially aligned with farmers and seed companies. However, by also establishing commercial relationships with consumer food companies and developing consumer brand awareness of our high value premium ingredients, we expect to be better positioned to garner a greater share of our product’s value proposition. Consumer food companies are looking to simplify their food ingredient formulations and consumer are demanding “clean labeling” in their foods, paying more for foods having fewer artificial ingredients and more natural, recognizable and healthy ingredients. A 2017 survey by PR agency Ingredient Communications found that 73 percent of consumers are happy to pay a higher retail price for a food or drink product made with ingredients they recognize. Because we increase nutrient density directly in the primary grains and oils, we provide the mechanism for food formulation simplification naturally, cost effectively and in a time-frame to meet evolving consumer demands. Our branding strategy is to link consumer’s health and nutrition appreciation with the nutrients we source directly from the farm, enabling us to share premium economics throughout the ag-food supply chain.

This forward migration in the ag-food supply chain will require that we build additional organizational capabilities and industry expertise. For instance, we are expanding our in-house commercial grain production and logistics resources for greater scale capacity to bring our products to market. We are also developing product branding strategies to build customer brand recognition and loyalty.

Since our inception, we have devoted substantially all our efforts to research and development activities, including the discovery, development, and testing of our traits and products in development incorporating our traits. To date, we have not generated revenues from sales of commercial products, other than limited revenues from our SONOVA products.  We do receive revenues from fees associated with the licensing of our traits to commercial partners. Our long-term business plan and growth strategy is based in part on our expectation that revenues from products that incorporate our traits will comprise a significant portion of our future revenues.

17

We have never been profitable and had an accumulated deficit of $191.0 million as of March 31, 2019. We incurred net losses of $12.6 million and $10.6 million for the three months ended March 31, 2019 and 2018, respectively. We expect to incur substantial costs and expenses before we obtain any revenues from the sale of seeds or ingredients incorporating our traits. As a result, our losses in future periods could become even more significant, and we may need additional funding to support our operating activities.

Arcadia Specialty Genomics^TM

In February 2019, we announced the establishment of Arcadia Specialty Genomics^TM (“ASG”) a new strategic business unit dedicated to developing and commercializing genetic improvements targeting plant content, quality, climate resiliency and overall yield in cannabis, a new crop for the company. ASG intends to conduct its business in only federal and state markets in which its activities are legal.

The recent passage of the U.S. Agriculture Improvement Act of 2018 – also known as the Farm Bill – confirmed the federal legalization of hemp, the term given to non-psychoactive cannabis containing less than 0.3% tetrahydrocannabinol (THC). It also included provisions for legalizing on a federal level hemp’s cultivation, transport and sale for the first time in more than 75 years. Hemp, previously considered a Schedule 1 drug and banned as an agricultural crop, lacks substantive plant biology research and suffers from suboptimal genetics, highly fragmented germplasm and rampant inconsistencies. As with our wheat and soybean products, we plan to create hemp-based solutions that allow farmers to be more productive and enable consumer packaged goods companies to differentiate their brands in the marketplace. In the near term, our focus will be on acquiring federal and state licensure in key geographies to launch our research and pilot programs, for which we expect to begin operations in early 2019. In parallel, we are evaluating key partnerships to extend our capabilities vertically to maximize the value creation potential of our innovations.

The Hemp Business Journal estimates the hemp CBD market – the primary non-psychoactive compound in cannabis – totaled $190 million in 2018. By 2022, the Brightfield Group, a cannabis and CBD market research firm, projects sales to reach $22 billion.

Components of Our Statements of Operations Data

Revenues

We derive our revenues from product revenues, licensing agreements, contract research agreements, and government grants. Given our acute focus on the near-term commercialization of our nutritional ingredient traits and products, we do not intend to continue pursuing contract research agreements and government grant projects at the levels we have historically. Over the next six to 15 months, we expect these revenues to decline as our current contract research agreements and government grant projects conclude and not replaced. Concurrently, as we introduce our new nutritional ingredient traits and products to the market, we expect revenues to increase from such activities. Furthermore, with the implementation of ASC Topic 606, future license revenues will no longer include the amortization of deferred up-front license fees from existing license agreements.  

Product Revenues

Our product revenues to date have consisted solely of sales of our SONOVA products. We generally recognize revenue from product sales upon sale to our third-party distributors or customers. Our revenues fluctuate depending on the timing of orders from our customers and distributors.

Contract Research and Government Grant Revenues

Contract research and government grant revenues consist of amounts earned from performing contracted research primarily related to breeding programs or the genetic engineering of plants for third parties. Contract research revenue will continue to be accounted for as a single performance obligation for which revenues are recognized over time using the input method (e.g. costs incurred to date relative to the total estimated costs at completion). In addition, we are entitled to receive a portion of the revenues generated from sales of products that incorporate our seed traits. Products expected to result from such contract research are in various stages of the product development cycle and we expect to generate revenues from the sale of any such products in as soon as the next two to four years.

We receive payments from government entities in the form of government grants. Government grant revenue will continue to be accounted for as a single performance obligation for which revenues are recognized over time using the input method (e.g. costs incurred to date relative to the total estimated costs at completion). Our obligation with respect to these agreements is to perform the research on a best-efforts basis. Given the nature and uncertain timing of receipt of government grants and timing of eligible research and development expenses, such revenues are likely to fluctuate significantly from period to period.

18

Operating Expenses

Cost of Product Revenues

Cost of product revenues relates to the sale of our SONOVA products and consists of in-licensing and royalty fees, any adjustments or write-downs to inventory, as well as the cost of raw materials, including inventory and third-party services costs related to procuring, processing, formulating, packaging, and shipping our SONOVA products.

Research and Development Expenses

Research and development expenses consist of costs incurred in the discovery, development, and testing of our products and products in development incorporating our traits. These expenses consist primarily of employee salaries and benefits, fees paid to subcontracted research providers, fees associated with in-licensing technology, land leased for field trials, chemicals and supplies, and other external expenses. These costs are expensed as incurred. Additionally, we are required from time to time to make certain milestone payments in connection with the development of technologies in-licensed from third parties. We expense these milestone payments at the time the milestone is achieved and deemed payable. Our research and development expenses may fluctuate from period to period as a result of the timing of various research and development projects.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses consist primarily of employee costs, professional service fees, and overhead costs. Our selling, general, and administrative expenses may fluctuate from period to period. In connection with our commercialization activities for our consumer ingredient products, we expect to increase our investments in sales and marketing and business development.

Other Income, Net

Other income, net, consists of interest income and the amortization of investment premium and discount on our cash and cash equivalents and investments.

Initial Loss on Common Stock Warrant and Common Stock Adjustment Feature Liabilities

Initial loss on common stock warrant and common stock adjustment feature liabilities is comprised of the loss associated with the initial recognition of the common stock warrant and common stock adjustment feature liabilities associated with the March 2018 Private Placement at their respective fair values.

Change in the Estimated Fair Value of Common Stock Warrant and Common Stock Adjustment Feature Liabilities

Change in the estimated fair value of common stock warrant liabilities and common stock adjustment feature liability is comprised of the fair value remeasurement of the liabilities associated with the March 2018 Private Placement and the June 2018 Private Placement.

Offering Costs

Offering costs consists of the costs incurred with the issuance of Common Stock and the March 2018 Warrants in connection with the March 2018 Private Placement. Also included are costs incurred with the June 2018 Offering and June 2018 Private Placement that have been allocated to the common stock warrant liability. Costs include placement agent, legal, advisory, accounting and filing fees.

Income Tax Provision

Our income tax provision has not been historically significant, as we have incurred losses since our inception. The provision for income taxes consists of state and foreign income taxes. Due to cumulative losses, we maintain a valuation allowance against our U.S. deferred tax assets as of March 31, 2019 and 2018. We consider all available evidence, both positive and negative, including but not limited to, earnings history, projected future outcomes, industry and market trends and the nature of each of the deferred tax assets in assessing the extent to which a valuation allowance should be applied against our U.S. deferred tax assets.

Revenues

Product revenues accounted for 68% and 29% of our total revenues in the three months ended March 31, 2019 and 2018, respectively. Our product revenues from sales of our SONOVA products increased by $46,000, or 75%, in the quarter-to-quarter comparison, due to the timing of orders.

Contract research and government grant revenues accounted for 32% and 71% of our total revenues for the three months ended March 31, 2019 and 2018, respectively. Our contract research and government grant revenues decreased by $102,000, or 67%, in the three months ended March 31, 2019 compared to the same period in 2018. The decrease was primarily driven by the completion of agreements and grants during 2018, as well as less activity for existing grants. Contract research and government grant revenues can vary from year-to-year depending on the timing of contract research projects and the completion of services provided, and the timing of eligible research and development expenses. Given our acute focus on the near-term commercialization of our nutritional ingredient traits and products, we do not intend to continue pursuing contract research agreements and government grant projects at the levels we have historically. We expect these revenues to continue to decline as our current contract research agreements and government grant projects conclude and are not replaced.

Cost of Product Revenues

Cost of product revenues increased by $23,000, or 64%, in the three months ended March 31, 2019 compared to the three months ended March 31, 2018. This was due to increased product revenues this year.

Research and Development

Research and development expenses increased by $109,000, or 8%, in the three months ended March 31, 2019 compared to the three months ended March 31, 2018. The increase was primarily driven by the timing of expenses relating to Verdeca, partially offset by lower employee-related expenses.

Selling, General, and Administrative

Selling, general, and administrative (SG&A) expenses increased by $191,000, or 7%, in the three months ended March 31, 2019 compared to the three months ended March 31, 2018. The increase was primarily driven by higher employee expenses due to the establishment of the commercial development team. We expect SG&A expenses to continue to increase as we hire additional personnel.

20

Other Income, Net

Other income, net, of $120,000 for the three months ended March 31, 2019 was an increase of $82,000, or 216%, in income when compared to other income for the three months ended March 31, 2018. The increase was primarily related to the higher investment balance in 2019.

Initial Loss on Common Stock Warrant and Common Stock Adjustment Feature Liabilities

Initial loss on common stock warrant and common stock adjustment feature liabilities of $4.0 million is comprised of the non-cash loss associated with the initial recognition of the March 2018 Warrants and Common Stock adjustment feature liabilities associated with the March 2018 Private Placement at estimated fair values of $10.2 million and $3.8 million, respectively. The combined fair value of $14 million less $10 million of proceeds yields the $4.0 million initial loss. There was no such loss in the first quarter of 2019.

Change in the Estimated Fair Value of Common Stock Warrant Liabilities and Common Stock Adjustment Feature Liability

Change in the estimated fair value of $8.5 million for the three months ended March 31, 2019 includes the fair value remeasurement of the March 2018 Warrants issued with the March 2018 Purchase Agreement and the June 2018 Offering. The estimated fair value of the March 2018 Warrants increased by $4.0 million and the estimated fair value of the June 2018 Offering Warrants increased by $4.5 million, both driven by the increase in the Company’s stock price. Change in the estimated fair value of $1.9 million for the three months ended March 31, 2018 includes the fair value remeasurement of the March 2018 Warrants and the Common Stock adjustment feature associated with the March 2018 Purchase Agreement. The estimated fair value of the common stock adjustment feature increased by $2.2 million and the estimated fair value of the common stock warrants decreased by $300,000. See Note 8.

Offering Costs

There were no offering costs expensed in the three months ended March 31, 2019. Offering costs for the three months ended March 31, 2018 of $904,000was comprised of placement agent fees, placement agent warrants, advisory fees, legal and accounting fees and registration filing fees related to the June 2018 Private Placement and June 2018 Offering.

Income Tax Provision

Income tax provision of $19,000 for the three months ended March 31, 2019 was consistent with the $10,000 recorded for three months ended March 31, 2018.

Seasonality

We and our commercial partners operate in different geographies around the world and conduct field trials used for data generation, which must be conducted during the appropriate growing seasons for particular crops and markets. Often, there is only one crop-growing season per year for certain crops and markets. Similarly, climate conditions and other factors that may influence the sales of our products may vary from season to season and year to year. In particular, weather conditions, including natural disasters such as heavy rains, hurricanes, hail, floods, tornadoes, freezing conditions, drought, or fire, may affect the timing and outcome of field trials, which may delay milestone payments and the commercialization of products incorporating our seed traits. In the future, sales of commercial products that incorporate our seed traits will vary based on crop growing seasons and weather patterns within particular regions.

The level of seasonality in our business overall is difficult to evaluate at this time due to our relatively early stage of development, our relatively limited number of commercialized products, our expansion into new geographical markets, and our introduction of new products and traits.

Liquidity, Capital Resources, and Going Concern

We have funded our operations primarily with the net proceeds from our initial public offering and private placements of equity and debt securities, as well as proceeds from the sale of our SONOVA products and payments under license agreements, contract research agreements, and government grants. Our principal use of cash is to fund our operations, which are primarily focused on progressing our agricultural yield and product quality seed traits through the regulatory process and to commercialization. This includes replicating field trials, coordinating with our partners on their development programs, and collecting, analyzing, and submitting field trial data to regulatory authorities. As of March 31, 2019, we had cash and cash equivalents of $10.4 million and short-term investments of $7.4 million. For the three months ended March 31, 2019 and the twelve months ended December 31, 2018, the Company had net losses of $12.6 and $13.5 million, and net cash used in operations of $4.0 million and $13.6 million, respectively. The majority of the loss in the first quarter of 2019 was due to the warrant $8.5 million non-cash expense resulting from the quarterly remeasurement of the common stock warrant liabilities.

21

As is disclosed in Note 8, the Company has obtained funding through two separate arrangements during the first half of 2018. On March 19, 2018, the Company entered into securities purchase agreements with institutional investors in connection with a private placement of common stock and warrants in the amount of $10 million, exclusive of any related transaction fees. On June 11, 2018, the Company entered into agreements with institutional investors through a registered direct offering in the amount of $14 million, exclusive of any related transaction fees.

We believe that our existing cash, cash equivalents, and short-term investments will not be sufficient to meet our anticipated cash requirements for at least the next 12 months which raises substantial doubt about the Company’s ability to continue as a going concern.  See Note 1 of the notes to our consolidated financial statements for more information.

We may seek to raise additional funds through debt or equity financings, if necessary. We may also consider entering into additional partner arrangements. Our sale of additional equity would result in dilution to our stockholders. Our incurrence of debt would result in debt service obligations, and the instruments governing our debt could provide for additional operating and financing covenants that would restrict our operations. If we do require additional funds and are not able to secure adequate additional funding, we may be forced to reduce our spending, extend payment terms with our suppliers, liquidate assets, or suspend or curtail planned development programs. Any of these actions could materially harm our business, results of operations and financial condition.

22

Cash provided in financing activities for the three months ended March 31, 2018 consisted of proceeds from the issuance of stock and warrants relating to March 2018 Private Placement totaling $10.0 million, partially offset by $932,000 of offering costs paid during the quarter.  Proceeds from the exercise of stock options and purchase of ESPP shares totaled $966,000.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, including the use of structured finance, special purpose entities, or variable interest entities other than Verdeca, which is discussed in the notes to our condensed consolidated financial statements.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenue generated, and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We consider our critical accounting policies and estimates to be revenue recognition, inventories, income taxes, the liabilities relating to the March 2018 Purchase Agreement and the June 2018 Offering, and stock-based compensation. See Notes 4 and 8 for the estimates made in connection with the securities purchase agreements executed during the first six months of 2018.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not Required.

ITEM 4: CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, or Exchange Act, that are designed to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our President and Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Our disclosure controls and procedures have been designed to meet reasonable assurance standards. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any disclosure controls and procedures also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Based on their evaluation as of the end of the period covered by this Quarterly Report on Form 10-Q, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) identified in connection with the evaluation identified above that occurred during the quarter ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Description of Business and Basis of Presentation

1. Description of Business and Basis of Presentation

Organization

Arcadia Biosciences, Inc. (the “Company”) was incorporated in Arizona in 2002 and maintains its headquarters in Davis, California, with additional facilities in Phoenix, Arizona, and American Falls, Idaho. The Company was reincorporated in Delaware in March 2015.

We are a consumer-driven, agricultural food ingredient company and proven leader in agricultural innovation to improve the quality and nutritional content of crops. We aim to create value across the agricultural production and supply chain beginning with enhanced crop productivity for farmers and ultimately delivering accelerated innovation in nutritional quality consumer foods.  We use state of the art gene-editing technology and advanced breeding techniques to naturally enhance the nutritional quality of grains and oilseeds to address the rapidly evolving trends in consumer health and nutrition. In addition, we have developed high value crop productivity traits designed to enhance farm economics.  

In February 2012, the Company formed Verdeca LLC (“Verdeca,” see Note 5), which is jointly owned with Bioceres Crop Solutions Corp. (“Bioceres”), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development cooperative. Verdeca, which is consolidated by the Company, was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies.

Reverse Stock Split

In January 2018, the Company’s board of directors and its shareholders approved a reverse split of 1:20 on the Company’s issued and outstanding common stock which became effective on January 23, 2018. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the condensed consolidated financial statement have been retroactively adjusted to reflect the reverse stock split for all periods presented. The reverse stock split did not change the total number of authorized shares of common stock which remained at one hundred and fifty million shares.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and Verdeca in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities (“VIEs”). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Verdeca, which is a VIE. The Company evaluates its relationships with the VIEs upon the occurrence of certain significant events that affect the design, structure or other factors pertinent to the primary beneficiary determination. Interim results are not necessarily indicative of results for any other interim period or for the full fiscal year. The information included in these condensed consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included herein and Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K, filed with the SEC on April 1, 2019.

Liquidity, Capital Resources, and Going Concern

As of March 31, 2019, the Company had an accumulated deficit of $191.0 million, cash and cash equivalents of $10.4 million and short-term investments of $7.4 million. For the three months ended March 31, 2019 and the twelve months ended December 31, 2018, the Company had net losses of $12.6 and $13.5 million, and net cash used in operations of $4.0 million and $13.6 million, respectively. The Company believes that its existing cash, cash equivalents and investments will be insufficient to meet its anticipated cash requirements for at least through March 2020, and thus raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The Company may seek to raise additional funds through debt or equity financings. The Company may also consider entering into additional partner arrangements. The sale of additional equity would result in dilution to the Company’s stockholders. The incurrence of debt would result in debt service obligations, and the instruments governing such debt could provide for additional operating and financing covenants that would restrict operations. If the Company does require additional funds and is unable to secure adequate additional funding at terms agreeable to the Company, the Company may be forced to reduce spending, extend payment terms with suppliers, liquidate assets, or suspend or curtail planned development programs. Any of these actions could materially harm the business, results of operations and financial condition.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Pronouncements

2. Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaces most existing revenue recognition guidance in U.S. GAAP. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, which defers the effective date of ASU No. 2014-09 by one year allowing early adoption as of the original effective date January 1, 2017. The standard was adopted on January 1, 2018.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Based on the new standard, lessees recognize lease assets and lease liabilities for leases classified as operating leases under previous GAAP and disclose qualitative and quantitative information about leasing arrangements with terms longer than 12 months. The adoption required recording right-of-use assets and corresponding lease obligation liabilities for the current operating leases. The Company has adopted ASU No. 2016-02 on January 1, 2019. See Note 7.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments affect loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of ASU No. 2016-13 on its consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments address cash flow issues such as debt prepayment or debt extinguishment costs and zero-coupon debt instruments. The amendments in this update are effective for fiscal years beginning after December 15, 2018, and interim periods within fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. The amendments are to be applied using a retrospective transition method to each period presented. If it is impractical to retrospectively apply, it can be applied prospectively as of the earliest date practicable. The Company adopted ASU No. 2016-15 on January 1, 2019 with no material impact to the consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13 Fair Value Measurement (Topic 820) – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. The amendments affect any entity required to make disclosures about recurring or nonrecurring fair value measurements. The amendments are effective for all entities for fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact of the adoption of ASU No. 2018-13 on its consolidated financial statements.

Available-for-Sale Investments

The Company classified short-term investments as “available-for-sale.” These short-term investments are free of trading restrictions. The investments are carried at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses, net of taxes, are included in accumulated other comprehensive loss, which is reflected as a separate component of stockholder’s equity in the Consolidated Balance Sheets. Gains and losses are recognized when realized in the Consolidated Statements of Operations and Comprehensive Loss.

The following tables summarize the amortized cost and fair value of the available-for-sale investment securities portfolio at March 31, 2019 and December 31, 2018, and the corresponding amounts of unrealized gains and losses recognized in accumulated other comprehensive income:

The Company did not have any investment categories that were in a continuous unrealized loss position for more than three months as of March 31, 2019. Unrealized gains and losses amounts would be included in accumulated other comprehensive income or loss; however, none were reported during the periods presented.

As of March 31, 2019, for fixed income securities that were in unrealized loss positions, the Company has determined that (i) it does not have the intent to sell any of these investments, and (ii) it is not more likely than not that it will be required to sell any of these investments before recovery of the entire amortized cost basis. The Company anticipates that it will recover the entire amortized cost basis of such fixed income securities and has determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three months ended March 31, 2019.

Fair Value Measurement

Fair value accounting is applied for all financial assets and liabilities and non-financial assets and liabilities that are recognized or disclosed at fair value in the condensed consolidated financial statements on a recurring basis. Assets and liabilities recorded at fair value in the condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities, are as follows:

• Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date.

• Level 2 inputs are observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 inputs are unobservable inputs for the asset or liability.

The following table sets forth the fair value of the Company’s financial assets as of March 31, 2019 and December 31, 2018:

The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2019 or 2018. The Company’s financial instruments consist primarily of cash and cash equivalents, accounts receivable, short-term investments and accounts payable and accrued liabilities. For accounts receivable, accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of March 31, 2019 and December 31, 2018 were considered representative of their fair values due to their short term to maturity or repayment. Cash equivalents are carried at cost, which approximates their fair value.

The Company’s Level 3 liabilities, which were measured and recorded on a recurring basis, consist of liabilities related to the March 2018 Purchase Agreement and the June 2018 Offering described in Note 8. The following table sets forth the establishment of these liabilities, as well as a summary of the changes in the fair value (in thousands):

	(Level 3)
(Dollars in thousands)	Common Stock Warrant Liability - Purchase Agreement		Common Stock Warrant Liability - June Offering		Total
Balance as of December 31, 2018	$	2,354	$	2,729	$	5,083
Change in fair value		3,970		4,525		8,495
Balance as of March 31, 2019	$	6,324	$	7,254	$	13,578

In determining the fair value, the Company uses various valuation approaches within the fair value measurement framework. The valuation methodologies used for the Company’s instruments measured at fair value and their classification in the valuation hierarchy are summarized below:

• Money market funds, treasury bills, and U.S. government securities – Investments in money market funds, treasury bills, and U.S. government securities are classified within Level 1.  At March 31, 2019 and December 31, 2018 these investments were included on the consolidated balance sheets in cash and cash equivalents and short-term investments.

• Commercial paper, corporate securities – Investments in commercial paper and corporate securities are classified within Level 2. At March 31, 2019 these investments were included on the consolidated balance sheets in cash and cash equivalents and short-term investments. At December 31, 2018, commercial paper was included on the consolidated balance sheets in short-term investments.

• Purchase Agreement common stock warrant liability – The Company has outstanding warrants to purchase 1,282,832 shares of common stock that it issued to certain accredited investors and its placement agent on March 22, 2018 (as described in Note 8). The common stock warrants were classified as a liability within Level 3 based on the instrument’s adjustment features and a contingent cash payment feature. The estimated fair value of the common stock warrant liability was remeasured at March 31, 2019 utilizing a Black Scholes Merton Model with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss.

• June 2018 Offering common stock warrant liability – The Company has outstanding warrants to purchase 1,461,962 shares of common stock that it issued to certain accredited investors on June 14, 2018 (as described in Note 8). The common stock warrants are classified as a liability within Level 3 due to a contingent cash payment feature.  The estimated fair value of the common stock warrant liability was remeasured at March 31, 2019 utilizing a Black Scholes Merton Model with the changes recorded on the Company’s condensed consolidated statements of operations and comprehensive loss.

Variable Interest Entity

5. Variable Interest Entity

In February 2012, the Company formed Verdeca LLC (“Verdeca”), which is equally owned with Bioceres Crop Solutions Corp. (“Bioceres”), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development cooperative owned by approximately 300 shareholders, including some of South America’s largest soybean growers. Verdeca was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies.

The Company determined that a de facto agency relationship between the Company and Bioceres exists. The Company considers qualitative factors in assessing the primary beneficiary which include understanding the purpose and design of the VIE, associated risks that the VIE creates, activities that could be directed by the Company, and the expected relative impact of those activities on the economic performance of the VIE. Based on an evaluation of these factors, the Company concluded that it is the primary beneficiary of Verdeca.

Both the Company and Bioceres incur expenses in support of specific activities, as agreed upon by joint work plans, which apply fair market value to each partner’s activities. Unequal contributions of services are equalized by the partners through cash payments. Verdeca is not the primary obligor for these activities performed by the Company or Bioceres. Under the terms of the joint development agreement, the Company has incurred direct expenses and allocated overhead in the amounts of $243,000 and $286,000, for the three months ended March 31, 2019 and 2018, respectively.

Private Placement and Registered Direct Offering Disclosure

8. Private Placement and Registered Direct Offering  

Private Placement

On March 22, 2018, the Company issued 300,752 shares of its common stock (“Common Stock”) and warrants to purchase up to 300,752 shares of Common Stock with an initial exercise price equal to $45.75 (the “March 2018 Warrants”), in a private placement (the “March 2018 Private Placement”) in accordance with a securities purchase agreement (the “the March 2018 Purchase Agreement”) entered into with certain institutional and accredited investors (collectively, the “Purchasers”) on March 19, 2018. The number of shares of Common Stock, the number and exercise price of the March 2018 Warrants issued to the Purchasers were subject to adjustments as provided in the March 2018 Purchase Agreement.  The March 2018 Warrants are immediately exercisable, subject to certain ownership limitations, and expire five years after the date of issuance.

Following the adjustments as provided in the March 2018 Purchase Agreement, the number of shares issued to the Purchasers was 1,201,636, the total number of shares issuable upon exercise of the March 2018 Warrants was 1,282,832 and the per share exercise price of the March 2018 Warrants was $10.7258. These condensed consolidated financial statements reflect these additional issuances.

The aggregate net proceeds received by the Company from the March 2018 Private Placement was $8.7 million, consisting of gross proceeds of $10.0 million less offering costs of $1.3 million. The Company entered into the March 2018 Private Placement to secure additional capital to strengthen its cash resources required to launch its new health and nutrition ingredient product commercialization and production scale-up plans, as well as to continue the deregulation and commercialization of its stress tolerant HB4 soybean trait. More specifically, net proceeds have been and will continue to be used for working capital to fund the continued introgression of quality ingredient traits into elite germ plasm, additional seed bulk-up, increased planting acreage, consumer brand development and a number of other pre-commercialization and commercialization activities.

The adjustment feature for the Common Stock and the March 2018 Warrants were determined to be liabilities based on each instrument’s adjustment features and the contingent cash payment feature of the common stock warrants. The liabilities were accounted for at their respective fair values at inception using a Monte Carlo simulation model with the following assumptions: volatility of 100 percent, stock price of $32.52 and risk-free rate of 2.63%. At inception, the fair values of the Common Stock adjustment feature and the March 2018 Warrant liabilities were $3.8 million and $10.2 million, respectively. As the combined value of the liabilities exceeded the $10.0 million of proceeds, no value was assigned to the Common Stock issued and an initial loss of $4.0 million was recognized. The liabilities are marked-to-market and were valued at $15.9 million at March 31, 2018, resulting in an additional loss of $1.9 million in the first quarter of 2018.

In May 2018, following the March 2018 Private Placement’s final adjustment, the terms of the March 2018 Warrants and the number of Common Stock shares issuable in the March 2018 Private Placement became known and fixed. As a result, the common stock adjustment feature liability was marked-to-market and valued at $8.4 million at May 7, 2018, resulting in an additional loss of $2.4 million recognized in the second quarter of 2018. The Company subsequently reclassified the Common Stock adjustment feature liability’s balance of $8.4 million to stockholders’ equity. The March 2018 Warrant liability was marked-to-market and valued at $6.3 million at March 31, 2019, resulting in expense of $4.0 million recognized in the first quarter of 2019 as the contingent cash payment feature was still in effect.

Offering Costs

In connection with the March 2018 Private Placement, the Company paid to a placement agent an aggregate fee equal to $850,000.  The Company also granted warrants to purchase a total of 15,038 shares of common stock (the “March 2018 Placement Agent Warrants”) that have an exercise price per share equal to $41.5625 and a term of five years. The March 2018 Placement Agent Warrants were issued for services performed by the placement agent as part of the March 2018 Private Placement and were treated as offering costs.  The value of the March 2018 Placement Agent Warrants was determined to be $526,000 using the Black-Scholes Merton Model (the “Black-Scholes Model”) with input assumptions including the Company’s stock price, expected life of the warrants, stock price volatility determined from the Company’s historical stock prices and the volatility of a peer group, and the risk-free interest rate for the term of the warrants. The Company incurred additional offering costs totaling $458,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the March 2018 Private Placement. The offering costs, inclusive of the March 2018 Placement Agent Warrants, totaled $1.8 million, all of which was expensed in 2018.

Registered Direct Offering

On May 11, 2018, the Company filed a shelf Registration Statement on Form S-3 with the SEC which was declared effective on June 8, 2018. This registration statement allows the Company to sell any combination of Common Stock, preferred stock, warrants and units consisting of such securities in one or more offerings from time to time having an aggregate initial offering price of $50 million.

On June 11, 2018, the Company entered into agreements with several institutional and accredited investors (the “June 2018 Purchase Agreement”) for the purchase of 1,392,345 shares of its common stock at a purchase price of $9.93 per share for gross proceeds of $13.8 million (the “June 2018 Offering”). The 1,392,345 shares of Common Stock sold in the June 2018 Offering were issued pursuant to a prospectus, dated June 8, 2018, and a prospectus supplement dated June 11, 2018, in connection with a takedown from the Company’s shelf Registration Statement on Form S-3. The June 2018 Offering closed on June 14, 2018.

Additionally, in a concurrent private placement (the “June 2018 Private Placement”), the Company issued to the investors unregistered warrants to purchase up to 1,392,345 shares of Common Stock at a purchase price per warrant of $0.125, for gross proceeds of $174,000 (the “June 2018 Warrants”). The June 2018 Warrants, and the shares of Common Stock underlying the June 2018 warrants, have not been registered with the SEC and have an exercise price of $9.94 per share. Subject to certain ownership limitations, the June 2018 Warrants are exercisable upon issuance and expire five and one-half years after the date of issuance.

The aggregate net proceeds received by the Company for the June 2018 Offering were $12.8 million, consisting of gross proceeds of $14.0 million less offering costs of $1.2 million. The Company has used and intends to continue to use the net proceeds from this offering for general corporate purposes, including, but not limited to, scale-up of its GoodWheat^TM Resistant Starch wheat production, early commercialization activities, continued research and development activities and for general and administrative expenses.

The June 2018 Warrants were determined to be a liability as they have a contingent cash payment feature. The June 2018 Warrants were accounted for at their fair value at inception using the Black Scholes Model with the following assumptions: volatility of 108 percent, stock price of $8.20 and risk-free rate of 2.83%.  At inception, the fair value of the June 2018 Warrants was $9.0 million and the remaining $5.0 million of the $14.0 million of proceeds was allocated to the Common Stock using the residual method and accounted for as stockholders’ equity. The June 2018 Warrants were marked-to-market and valued at $7.3 million at March 31, 2019, resulting in expense of $4.5 million recognized in the first quarter of 2019.

Offering Costs

In connection with the June 2018 Offering, the Company paid to a placement agent an aggregate fee equal to $980,000.  The Company also granted warrants to purchase a total of 69,617 shares of common stock (“June 2018 Placement Agent Warrants”) that have an exercise price per share equal to $12.568 and a term of five years. The June 2018 Placement Agent Warrants were issued for services performed by the placement agent as part of the June 2018 Offering and were treated as offering costs. The value of the June 2018 Placement Agent Warrants was determined to be $427,000 using the Black-Scholes Model with input assumptions including the Company’s stock price, expected life of the warrants, stock price volatility determined from the Company’s historical stock prices and the volatility of a peer group, and the risk-free interest rate for the term of the warrants. The Company incurred additional offering costs totaling $226,000 that consist of direct incremental legal, advisory, accounting and filing fees relating to the June 2018 Offering. The offering costs, inclusive of the June 2018 Placement Agent Warrants, totaled $1.6 million and allocated to the June 2018 Warrants and the Common Stock using their relative fair values. A total of $721,000 was allocated to the June 2018 Warrants which was expensed in 2018. The remaining $912,000 was allocated to the common stock and offset to additional paid in capital.

Stock Incentive Plans

The Company has two equity incentive plans: the 2006 Stock Plan (“2006 Plan”) and the 2015 Omnibus Equity Incentive Plan (“2015 Plan”).

In 2006, the Company adopted the 2006 Plan, which provided for the granting of stock options to executives, employees, and other service providers under terms and provisions established by the Board of Directors. The Company granted non-statutory stock options (“NSOs”) under the 2006 Plan until May 2015, when the 2006 Plan was terminated as to future awards. The 2006 Plan continues to govern the terms of options that remain outstanding and were issued under the 2006 Plan. The 2015 Plan became effective in May 2015 and all shares that were reserved, but not issued, under the 2006 Plan were assumed by the 2015 Plan. Upon effectiveness, the 2015 Plan had 154,387 shares of common stock reserved for future issuance, which included 10,637 shares under the 2006 Plan that were transferred to and assumed by the 2015 Plan. The 2015 Plan provides for automatic annual increases in shares available for grant. In addition, shares subject to awards under the 2006 Plan that are forfeited or canceled will be added to the 2015 Plan. The 2015 Plan provides for the grant of incentive stock options (“ISOs”), NSOs, restricted stock awards, stock units, stock appreciation rights, and other forms of equity compensation, all of which may be granted to employees, officers, non-employee directors, and consultants. The ISOs and NSOs will be granted at a price per share not less than the fair value at the date of grant. Options granted generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly thereafter; however, the options granted in the third quarter of 2018 vest over a two-year period, vesting monthly on a pro-rated basis. Options granted, once vested, are generally exercisable for up to 10 years after grant.

As of March 31, 2019, a total of 538,953 shares of common stock were reserved for issuance under the 2015 Plan, of which 65,872 shares of common stock are available for future grant. As of March 31, 2019, a total of 62,162 and 473,081 options are outstanding under the 2006 and 2015 Plans, respectively.

A summary of activity under the stock incentive plans is as follows (in thousands, except share data and price per share):

Employee Stock Purchase Plan

The Company’s 2015 Employee Stock Purchase Plan (“ESPP”) became effective on May 14, 2015. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% of their eligible compensation through payroll deductions, subject to any plan limitations.   The ESPP provides for six-month offering periods, and at the end of each offering period, employees are able to purchase shares at 85% of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period. As of March 31, 2019, the number of shares of common stock reserved for future issuance under the ESPP is 108,864. The ESPP provides for automatic annual increases in the shares available for purchase beginning on January 1, 2016. As of March 31, 2019, 9,353 shares had been issued under the ESPP. The Company recorded $4,300 and $1,200 of compensation expense for the three months ended March 31, 2019 and 2018, respectively.

Income Taxes

10. Income Taxes

Income tax expense during interim periods is based on applying an estimated annual effective income tax rate to year-to-date income, plus any significant unusual or infrequently occurring items that are recorded in the interim period. The computation of the annual estimated effective tax rate at each interim period requires certain estimates and significant judgment including, but not limited to, the expected operating income for the year, projections of the proportion of income earned and taxed in various jurisdictions, permanent and temporary differences, and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is obtained, additional information becomes known, or as the tax environment changes.

The interim financial statement provision for income taxes expense is different from the amounts computed by applying the United States federal statutory income tax rate of 21%. The Company’s effective tax rate was -0.1% and -0.2% for the three months ended March 31, 2019 and 2018, respectively. The difference between the effective tax rate and the federal statutory rate of 21% was primarily due to the full valuation allowance recorded on the Company’s net deferred tax assets and foreign withholding taxes.

The Company may have experienced an ownership change under IRC Section 382 as a result of the common shares issued in connection with the March 2018 Purchase Agreement or in the June 2018 Offering. Such an ownership change may limit the Company’s ability to utilize its net operating loss carryforwards prior to expiration. Given the full valuation allowance, such a limitation would not impact the deferred tax asset balance as currently recorded.

As of March 31, 2019, there have been no material changes to the Company’s uncertain tax positions.

Contingent Liability Related to the Anawah Acquisition

11. Contingent Liability Related to the Anawah Acquisition

On June 15, 2005, the Company completed its agreement and plan of merger and reorganization with Anawah, Inc. (“Anawah”), to purchase the food and agricultural research company through a non-cash stock purchase. Pursuant to the merger with Anawah, and in accordance with the ASC 805 - Business Combinations, the Company incurred a contingent liability not to exceed $5.0 million. This liability represents amounts to be paid to Anawah’s previous stockholders for cash collected on revenue recognized by the Company upon commercial sale of certain specific products developed using technology acquired in the purchase. As of December 31, 2010, the Company ceased activities relating to three of the six Anawah product programs, thus, the contingent liability was reduced to $3.0 million. During the third quarter of 2016, one of the programs previously accrued for was abandoned and another program previously abandoned was reactivated. As of March 31, 2019, the Company continues to pursue three development programs using this technology and believes that the contingent liability is probable. As a result, $3.0 million remains on the Condensed Consolidated Balance Sheet as an other noncurrent liability.

Net Loss per Share

12. Net Loss per Share

Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period and excludes any dilutive effects of stock-based awards and warrants. Diluted net loss per share is computed giving effect to all potentially dilutive common shares, including common stock issuable upon exercise of stock options and warrants. As of March 31, 2019, all potentially dilutive common shares were determined to be anti-dilutive after evaluation.

Securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in shares):

Related-Party Transactions

13. Related-Party Transactions

The Company’s related parties include Moral Compass Corporation (“MCC”) and the John Sperling Foundation (“JSF”).  The rights to the intellectual property owned by Blue Horse Labs, Inc. (“BHL”) were assigned to its sole shareholder, the John Sperling Revocable Trust (“JSRT”) due to BHL’s dissolution and then subsequently to the JSF. The JSF is deemed a related party of the Company because MCC, the Company’s largest stockholder, and the JSF share common officers and directors.

JSF receives a single digit royalty from the Company when revenue has been collected on product sales or for license payments from third parties that involve certain intellectual property developed under research funding originally from BHL. Royalty fees due to JSF were $12,000 and $29,000 as of March 31, 2019 and December 31, 2018, respectively, and are included in the Condensed Consolidated Balance Sheets as amounts due to related parties.

Accounting Policies [Abstract]

Organization

Organization

Arcadia Biosciences, Inc. (the “Company”) was incorporated in Arizona in 2002 and maintains its headquarters in Davis, California, with additional facilities in Phoenix, Arizona, and American Falls, Idaho. The Company was reincorporated in Delaware in March 2015.

We are a consumer-driven, agricultural food ingredient company and proven leader in agricultural innovation to improve the quality and nutritional content of crops. We aim to create value across the agricultural production and supply chain beginning with enhanced crop productivity for farmers and ultimately delivering accelerated innovation in nutritional quality consumer foods.  We use state of the art gene-editing technology and advanced breeding techniques to naturally enhance the nutritional quality of grains and oilseeds to address the rapidly evolving trends in consumer health and nutrition. In addition, we have developed high value crop productivity traits designed to enhance farm economics.  

In February 2012, the Company formed Verdeca LLC (“Verdeca,” see Note 5), which is jointly owned with Bioceres Crop Solutions Corp. (“Bioceres”), a U.S. wholly owned subsidiary of Bioceres, S.A., an Argentine corporation. Bioceres, S.A. is an agricultural investment and development cooperative. Verdeca, which is consolidated by the Company, was formed to develop and deregulate soybean varieties using both partners’ agricultural technologies.

Reverse Stock Split

Reverse Stock Split

In January 2018, the Company’s board of directors and its shareholders approved a reverse split of 1:20 on the Company’s issued and outstanding common stock which became effective on January 23, 2018. All issued and outstanding common stock, options to purchase common stock and per share amounts contained in the condensed consolidated financial statement have been retroactively adjusted to reflect the reverse stock split for all periods presented. The reverse stock split did not change the total number of authorized shares of common stock which remained at one hundred and fifty million shares.

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and Verdeca in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial statements and are in the form prescribed by the Securities and Exchange Commission (the “SEC”) in instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods indicated. All material intercompany accounts and transactions have been eliminated in consolidation. The Company uses a qualitative approach in assessing the consolidation requirement for variable interest entities (“VIEs”). This approach focuses on determining whether the Company has the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance and whether the Company has the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the VIE. For all periods presented, the Company has determined that it is the primary beneficiary of Verdeca, which is a VIE. The Company evaluates its relationships with the VIEs upon the occurrence of certain significant events that affect the design, structure or other factors pertinent to the primary beneficiary determination. Interim results are not necessarily indicative of results for any other interim period or for the full fiscal year. The information included in these condensed consolidated financial statements and notes thereto should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations included herein and Management’s Discussion and Analysis of Financial Condition and Results of Operations and the consolidated financial statements and notes thereto for the fiscal year ended December 31, 2018 included in the Company’s Annual Report on Form 10-K, filed with the SEC on April 1, 2019.

Liquidity, Capital Resources, and Going Concern

Liquidity, Capital Resources, and Going Concern

As of March 31, 2019, the Company had an accumulated deficit of $191.0 million, cash and cash equivalents of $10.4 million and short-term investments of $7.4 million. For the three months ended March 31, 2019 and the twelve months ended December 31, 2018, the Company had net losses of $12.6 and $13.5 million, and net cash used in operations of $4.0 million and $13.6 million, respectively. The Company believes that its existing cash, cash equivalents and investments will be insufficient to meet its anticipated cash requirements for at least through March 2020, and thus raises substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

The Company may seek to raise additional funds through debt or equity financings. The Company may also consider entering into additional partner arrangements. The sale of additional equity would result in dilution to the Company’s stockholders. The incurrence of debt would result in debt service obligations, and the instruments governing such debt could provide for additional operating and financing covenants that would restrict operations. If the Company does require additional funds and is unable to secure adequate additional funding at terms agreeable to the Company, the Company may be forced to reduce spending, extend payment terms with suppliers, liquidate assets, or suspend or curtail planned development programs. Any of these actions could materially harm the business, results of operations and financial condition.
