Income Tax Disclosure [Abstract]

Income Taxes

5. INCOME TAXES

We provide for a valuation allowance when it is more likely than not that we will not realize a portion of the deferred tax assets. We have established a full valuation allowance for deferred tax assets due to the uncertainty that enough taxable income will be generated in the taxing jurisdiction to utilize the assets. Therefore, we have not reflected any benefit of such deferred tax assets in the accompanying consolidated financial statements.

As of June 30, 2021, there were no material changes to what we disclosed regarding tax uncertainties or penalties as of December 31, 2020.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Stock-Based Compensation

4. STOCK-BASED COMPENSATION

We use broad-based stock plans to attract and retain highly qualified officers and employees and to help ensure that management’s interests are aligned with those of our shareholders. We have also granted equity-based awards to directors, nonemployees, and certain employees of Cellectis.

In December 2014, we adopted the Calyxt, Inc. Equity Incentive Plan (2014 Plan), which allowed for the grant of stock options, and in June 2017, we adopted the 2017 Omnibus Plan (2017 Plan), which allowed for the grant of stock options, restricted stock units, performance stock units and other types of equity awards.

On February 19, 2021, James Blome ceased serving as our Chief Executive Officer. We recorded a benefit to earnings from a $2.5 million recapture of non-cash stock compensation expense from the forfeiture of Mr. Blome’s unvested stock options, restricted stock units, and performance stock units.

As of June 30, 2021, 1,634,125 shares were registered and available for grant under effective registration statements, while 5,950,199 shares were available for grant in the form of stock options, restricted stock, restricted stock units, and performance stock units under the 2017 Plan. On July 16, 2021, we filed a Registration Statement on Form S-8 with the SEC which registered an additional 4,299,904 shares of common stock that may be issued or delivered and sold pursuant to the 2017 Plan and 600,000 shares of common stock that may be issued or delivered and sold pursuant to the Calyxt, Inc. Employee Inducement Incentive Plan (the Inducement Plan). The Inducement Plan shares of common stock are issuable upon the settlement of performance stock units which were granted to Mr. Carr

as a material inducement to accept employment as our President and Chief Executive Officer. Stock-based awards currently outstanding also include awards granted under the 2014 Plan, under which no further awards will be granted.

Stock Options

The estimated fair values of stock options granted, and the assumptions used for the Black-Scholes option pricing model were as follows:


	Six Months Ended June 30,
	2021		2020
Estimated fair values of stock options granted	$	4.54	$	5.19
Assumptions:
Risk-free interest rate	0.6% - 1.1%			1.7	%
Expected volatility	80.1% - 82.0%			77.4	%
Expected term (in years)	5.5 - 6.5			6.9

We estimate the fair value of each option on the grant date, or other measurement dates if applicable, using a Black-Scholes option-pricing model, which requires us to make predictive assumptions regarding employee exercise behavior, future stock price volatility, and dividend yield. Our expected term represents the period that options granted are expected to be outstanding determined using the simplified method. We estimate our future stock price volatility using the historical volatility of comparable public companies over the expected term of the option. We estimate the risk-free interest rate based on the United States Treasury zero-coupon yield curve at the date of grant for the expected term of the option. We do not nor do we expect to pay dividends.

Option strike prices are set at 100 percent or more of the closing share price on the date of grant, and generally vest over three to six years following the grant date. Options generally expire 10 years after the date of grant.

Information on stock option activity is as follows:


	Options Exercisable		Weighted- Average Exercise Price Per Share		Options Outstanding			Weighted- Average Exercise Price Per Share
Balance as of December 31, 2020		2,347,663	$	10.15		4,621,173		$	10.30

Balance as of June 30, 2021		2,412,501	$	10.49		4,466,650		$	9.89

Stock-based compensation expense related to stock option awards is as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
In Thousands	2021		2020		2021		2020
Stock-based compensation expense	$	800	$	1,246	$	405	$	2,252

As of June 30, 2021, options outstanding and exercisable had an aggregate intrinsic value of $0.4 million and the weighted average remaining contractual term was 5.8 years.

Net cash proceeds from the exercise of stock options less shares used for minimum withholding taxes and the intrinsic value of options exercised were as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
In Thousands	2021		2020		2021		2020
Net cash proceeds	$	19	$	—	$	227	$	—
Intrinsic value of options exercised	$	13	$	—	$	344	$	—

As of June 30, 2021, unrecognized compensation expense related to non-vested stock options was $6.7 million. This expense will be recognized over 28 months on average.

Restricted Stock Units

We grant restricted stock units which generally vest over three to five years after the date of grant. Information on restricted stock unit activity is as follows:


	Number of Restricted Stock Units Outstanding			Weighted- Average Grant Date Fair Value
Unvested balance at December 31, 2020		547,807		$	9.49
Granted		234,504			5.61

As of June 30, 2021, unrecognized compensation expense related to restricted stock units was $2.1 million. This expense will be recognized over 24 months on average.

We treat stock-based compensation awards granted to employees of Cellectis as deemed dividends. We recorded deemed dividends as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
In Thousands	2021		2020		2021		2020
Deemed dividends from grants to Cellectis employees	$	107	$	198	$	28	$	422

Performance Stock Units

In June 2019, we granted 311,667 performance stock units under the 2017 Plan to three executive officers. The performance stock units will vest at 50%, 100% or 120% of the shares under the award at the end of a three-year performance period based upon increases in the value of our common stock from the grant price of $12.48. The performance stock units will be settled in restricted stock upon vesting, with restrictions on transfer lapsing on the second anniversary of the restricted stock issuance date. During the six months ended June 30, 2021, we recognized a benefit from the forfeiture of 166,667 performance stock units held by Mr. Blome, our former chief executive officer.

Stock-based compensation expense related to performance stock units is as follows:


	Three Months Ended June 30,				Six Months Ended June 30,
In Thousands	2021		2020		2021			2020
Stock-based compensation expense	$	51	$	110	$	(255	)	$	220

As of June 30, 2021, unrecognized compensation expense related to performance stock units was $0.6 million. This expense will be recognized over 36 months on average.

- Definition

Total of all stockholders' equity (deficit) items, net of receivables from officers, directors, owners, and affiliates of the entity which are attributable to the parent. The amount of the economic entity's stockholders' equity attributable to the parent excludes the amount of stockholders' equity which is allocable to that ownership interest in subsidiary equity which is not attributable to the parent (noncontrolling interest, minority interest). This excludes temporary equity and is sometimes called permanent equity.

Receivables from growers		175		570

Total	$	3,994	$	4,887

We carry receivables related to amounts we are owed by growers from their purchases of seed. These amounts reduce the cost of the grain we ultimately purchase from the grower and are repaid either on current terms or on an extended payment basis. If a grower has elected extended payment terms, they will pay a higher price per unit and grant us the right to deduct the amount we are owed from the

payment we make upon the purchase of their grain. As of June 30, 2021, and December 31, 2020 all of the receivables from growers were on extended payment terms.

Basis of Presentation & Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Net Loss Per Share	Net Loss Per Share All anti-dilutive stock options, restricted stock units, and performance stock units are excluded from the calculation of net loss per share. Due to our net loss position for the three and six months ended June 30, 2021, and June 30, 2020, all of our outstanding stock options, restricted stock units, and performance stock units are considered anti-dilutive and excluded from the calculation of net loss per share. Accordingly, the treasury method was not used in determining the number of anti-dilutive stock options and restricted stock units.
Risks and Uncertainties	Risks and Uncertainties Considering factors such as our anticipated cash receipts from sales of grain and our product development and technology licensing efforts with partners, our anticipated cash burn rate, and our expense reduction efforts, we believe our cash, cash equivalents, and restricted cash as of June 30, 2021, will be sufficient to fund our operations for at least the next twelve months and into the second half of 2022. We anticipate that we will continue to generate losses for the next several years before revenue is enough to support our operating capital requirements. Until we can generate substantial cash flow, we expect to finance a portion of future cash needs through cash on hand, commercialization activities, which may result in various types of revenue streams from seed sales and future development agreements, trait licenses, and technology licenses, including upfront and milestone payments, annual license fees, and royalties, government or other third-party funding, and public or private equity or debt financings. However, additional capital may not be available on reasonable terms, if at all. If we are unable to raise additional capital in enough amounts or on terms acceptable to us, we may have to significantly delay, scale back, or discontinue the development or commercialization of our activities. Failure to receive additional funding could cause us to cease operations, in part or in full. If we raise additional funds through the issuance of additional debt or equity securities, it could result in dilution to our existing stockholders and increased fixed payment obligations, and these securities may have rights senior to those of our shares of common stock. Any of these events could significantly harm our business, financial condition, and prospects.

Accounting Policies [Abstract]

Basis of Presentation & Summary of Significant Accounting Policies

1. BASIS OF PRESENTATION & SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Our unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP or GAAP) for interim financial information and with the rules and regulations of the Securities and Exchange Commission (SEC) applicable to interim financial statements. In our opinion, the accompanying consolidated financial statements reflect all adjustments necessary for a fair presentation of our statements of financial position, results of operations, and cash flows for the periods presented but they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Except as otherwise disclosed herein, these adjustments consist of normal recurring items. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole or any other interim period.

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the consolidated financial statements and during the reporting period. Actual results could materially differ from these estimates.

Certain prior year amounts have been reclassified to conform to the current year presentation.

For further information, refer to the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020, filed with the SEC on March 4, 2021. The accompanying Balance Sheet as of December 31, 2020, was derived from the audited consolidated financial statements. This Quarterly Report on Form 10-Q should be read in conjunction with our consolidated financial statements and notes included in the Annual Report on Form 10-K for the year ended December 31, 2020.

Risks and Uncertainties

Considering factors such as our anticipated cash receipts from sales of grain and our product development and technology licensing efforts with partners, our anticipated cash burn rate, and our expense reduction efforts, we believe our cash, cash equivalents, and restricted cash as of June 30, 2021, will be sufficient to fund our operations for at least the next twelve months and into the second half of 2022.

We anticipate that we will continue to generate losses for the next several years before revenue is enough to support our operating capital requirements. Until we can generate substantial cash flow, we expect to finance a portion of future cash needs through cash on hand, commercialization activities, which may result in various types of revenue streams from seed sales and future development agreements, trait licenses, and technology licenses, including upfront and milestone payments, annual license fees, and royalties, government or other third-party funding, and public or private equity or debt financings. However, additional capital may not be available on reasonable terms, if at all. If we are unable to raise additional capital in enough amounts or on terms acceptable to us, we may have to significantly delay, scale back, or discontinue the development or commercialization of our activities. Failure to receive additional funding could cause us to cease operations, in part or in full. If we raise additional funds through the issuance of additional debt or equity securities, it could result in dilution to our existing stockholders and increased fixed payment obligations, and these securities may have rights senior to those of our shares of common stock. Any of these events could significantly harm our business, financial condition, and prospects.

Net Loss Per Share

All anti-dilutive stock options, restricted stock units, and performance stock units are excluded from the calculation of net loss per share. Due to our net loss position for the three and six months ended June 30, 2021, and June 30, 2020, all of our outstanding stock options, restricted stock units, and performance stock units are considered anti-dilutive and excluded from the calculation of net loss per share. Accordingly, the treasury method was not used in determining the number of anti-dilutive stock options and restricted stock units.

6. LEASES, OTHER COMMITMENTS, AND CONTINGENCIES

Litigation and Claims

We are not currently a party to any material pending legal proceeding.

Leases

We lease our headquarters facility, office equipment, and other items. Our headquarters lease involved the sale of land and improvements to a third-party who then constructed the facility. This lease is considered a financing lease.

We also have an equipment financing arrangement that is considered a financing lease. This arrangement has a term of four years for each draw. We were required to deposit cash into a restricted account in an amount equal to the future rent payments required by the lease. As of June 30, 2021, restricted cash totaled $1.0 million. We have the option to request the return of excess collateral annually in December, and the amount we expect to receive is reflected as a current asset.

Rent expense from operating leases was as follows:

In Thousands	2021		2020		2021		2020
Rent expense from operating leases	$	11	$	23	$	24	$	47

Other Commitments

As of June 30, 2021, we have noncancelable commitments to purchase grain and seed from growers at dates throughout 2021 aggregating $6.8 million based on current commodity futures market prices, other payments to growers, and estimated yields per acre. This commitment is not recorded in the consolidated financial statements because we have not taken delivery of the seed or grain as of June 30, 2021.

Financial Instruments Measured at Fair Value and Concentrations of Credit Risk

2. FINANCIAL INSTRUMENTS MEASURED AT FAIR VALUE AND CONCENTRATIONS OF CREDIT RISK

Financial Instruments Measured at Fair Value and Financial Statement Presentation

Financial instruments including cash and cash equivalents, restricted cash, accounts payable, and all other current liabilities have carrying values that approximate fair value. We measure short-term investments and commodity derivative contracts at fair value on a

recurring basis. The accounting guidance establishes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value as of the measurement date as follows:

Level 1: Fair values are based on unadjusted quoted prices in active trading markets for identical assets and liabilities.

Level 2: Fair values are based on observable quoted prices other than those in Level 1, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.

Level 3: Fair values are based on at least one significant unobservable input for the asset or liability.

Fair Value Measurements and Financial Statement Presentation

The fair values of our financial instruments measured at fair value and their respective levels in the fair value hierarchy as of June 30, 2021, and December 31, 2020, were as follows:


	June 30, 2021								June 30, 2021

Total	$	12,165	$	—	$	—	$	12,165	$	—	$	—	$	—	$	—

The non-current portion of our financing lease obligations are also considered a financial instrument, which we measure at fair value for disclosure purposes. It is a Level 2 liability and had a fair value of $14.9 million as of June 30, 2021, and a fair value of $15.2 million as of December 31, 2020.

Commodity Price Risk

We enter into seed and grain production agreements with settlement values based on commodity futures market prices (Forward Purchase Contracts). These Forward Purchase Contracts allow the counterparty to fix their sales prices at various times as defined in the contract. Because we intend to take physical delivery under the Forward Purchase Contracts, we have grain inventory we will need to sell. We intend to sell these inventories at then-current market prices. As a result, when the Forward Purchase Contract counterparty fixes their grain prices, we enter hedging arrangements by selling futures contracts which converts our exposure to these fixed prices to floating prices. We expect to maintain these hedging relationships until such grain inventory is sold to help stabilize our margins. We do not account for these economic hedges as accounting hedges. We expect any gains or losses from these hedging arrangements to be offset by gains or losses on the grain inventories when such grain inventories are sold. As of June 30, 2021, we held commodity contracts with a notional amount of $8.0 million. As of June 30, 2021, those commodity contracts carried an unrealized loss of $1.0 million that had been recognized in earnings over the period from their acquisition to June 30, 2021, and that may be realized in the future depending upon the timing of the liquidation of those positions which is based on our future grain sales and changes in soybean prices.

Prior to August 1, 2020, we designated all our commodity derivative contracts as cash flow hedges based on the nature of our business activities. As a result, all gains or losses associated with recording those commodity derivative contracts at fair value were recorded as a component of accumulated other comprehensive income (loss) (AOCI). We reclassified amounts from AOCI to cost of goods sold when we sold the underlying products to which those hedges related. For the three and six months ended June 30, 2020, we reclassified an immaterial amount from AOCI to cost of goods sold, and there were no such reclassifications in the same period in 2021.

Foreign Exchange Risk

Foreign currency fluctuations affect our foreign currency cash flows related primarily to payments to Cellectis. Our principal foreign currency exposure is to the euro. We do not hedge these exposures, and we do not believe that the current level of foreign currency risk is significant to our operations.

Concentrations of Credit Risk

We invest our cash, cash equivalents, and restricted cash in highly liquid securities and investment funds. We diversify the risk posed by exceeding deposit insurance limits by allocating from time-to-time certain investments to a diverse portfolio of short-dated, high investment-grade securities, which we classify as short-term investments that are recorded at fair value in our consolidated financial statements. We ensure the credit risk in this portfolio is in accordance with our internal policies and if necessary, make changes to investments to ensure credit risk is minimized. We have not experienced any counterparty credit losses. As of June 30, 2021, we did not hold any short-term investments.

Long-Term Debt

Debt Disclosure [Abstract]

Long-Term Debt

9. LONG-TERM DEBT

Our long-term debt was comprised of a $1.5 million promissory note pursuant to the Paycheck Protection Program (the PPP loan) established by the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) implemented by the U.S. Small Business Administration (SBA). We received the funds under the PPP loan on April 19, 2020. Subject to certain conditions, the PPP loan and accrued interest were eligible to be forgiven in whole or in part by applying for forgiveness pursuant to the CARES Act and the Paycheck Protection Program. In order to be eligible for forgiveness, the proceeds of the PPP loan were required to be applied to certain eligible expenses, including payroll costs, interest on certain mortgage obligations, rent payments on certain leases, and certain qualified utility payments, with not more than 40 percent of the amount applied to non-payroll costs.

We applied the proceeds from the PPP loan toward qualifying expenses. On October 21, 2020, as modified December 29, 2020, we applied for forgiveness of the full principal amount and all accrued interest. On April 8, 2021, we were notified by the SBA that the full principal amount and all accrued interest of the PPP loan had been forgiven. Accordingly, we recognized a gain upon the extinguishment of the PPP loan for $1.5 million in the three months ended June 30, 2021.

Related-Party Transactions

3. RELATED-PARTY TRANSACTIONS

We have several agreements that govern our relationship with Cellectis, some of which require us to make payments to Cellectis. Pursuant to our management services agreement with Cellectis, we incurred nominal management fee expenses for the three and six months ended June 30, 2021, and 2020.

Cellectis has also guaranteed the lease agreement for our headquarters. Cellectis’ guarantee of our obligations under the lease will terminate at the end of the second consecutive calendar year in which our tangible net worth exceeds $300 million.

TALEN® is our primary gene editing technology, and it is the foundation of our technology platform. TALEN® technology was invented by researchers at the University of Minnesota and Iowa State University and exclusively licensed to Cellectis. We obtained an exclusive license for the TALEN® technology for commercial use in plants from Cellectis. We also license other technology from Cellectis. We owe Cellectis royalties on any revenue we generate from sales of products less certain amounts as defined in the license agreement, royalties on certain cumulative revenue thresholds, and a percentage of any sublicense revenues. We have incurred nominal license and royalty fees for the three and six months ended June 30, 2021, and 2020.

We have entered into various agreements with the University of Minnesota, pursuant to which we have been granted both exclusive and non-exclusive license agreements that carry annual license fees, milestone payments, royalties, and associated legal fees. These agreements primarily relate to gene-editing tools, enabling technologies and germplasm. We incurred nominal expenses pursuant to these agreements for the three and six months ended June 30, 2021, and 2020.
