Under the Registration Rights Agreement, in the event that the Company receives a written request from the Innovatus Investors that the Company file with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement covering the resale of all of the Shares, the Company shall promptly but no later than 120 days after the date of such request prepare and file with the SEC such registration statement. The Innovatus Investors have agreed to use best efforts not to make such a request, including by effecting any planned sales of Shares under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”). The Company has agreed to use commercially reasonable efforts to cause such registration statement to become effective and to keep such registration statement effective until the date the Shares covered by such registration statement have been sold or may be resold pursuant to Rule 144 without restriction. The Company has agreed to be responsible for all fees and expenses incurred in connection with the registration of the Shares.

Shelf registration In January 2017, the Company filed a shelf registration statement on Form S-3, which was declared effective by the SEC on May 9, 2017 (the "Shelf Registration Statement"). The Shelf Registration Statement allows the Company to sell from time to time up to $200 million of common stock, preferred stock, debt securities, warrants, or units comprised of any combination of these securities, for its own account in one or more offerings. On May 10, 2017, the Company filed with the SEC a prospectus supplement (the “Prospectus Supplement”) for the sale and issuance of up to $50 million of its common stock and entered into an Equity Distribution Agreement (“Distribution Agreement”) with Canaccord Genuity LLC (formerly, Canaccord Genuity Inc.) ("Canaccord") pursuant to which Canaccord agreed to sell shares of the Company's common stock from time to time, as its agent, in an “at-the-market” ("ATM") offering as defined in Rule 415 promulgated under the U.S. Securities Act of 1933, as amended (the "Securities Act"). The Company was not obligated to sell any shares under the Distribution Agreement. On August 4, 2020, the Company and Canaccord mutually agreed to terminate the Distribution Agreement and as of that date, the Company had sold 2,663,000 shares under the Distribution Agreement resulting in net proceeds of $4.4 million.

The Company will pay Cowen a commission of up to 3.0% of the gross sales proceeds of any Common Stock sold through Cowen under the Sales Agreement, and we also provided Cowen with customary indemnification rights. The shares of Common Stock being offered pursuant to the Sales Agreement will be offered and sold pursuant to the New Shelf Registration Statement. The Company is not obligated to make any sales of Common Stock under the Sales Agreement. The offering of shares of Common Stock pursuant to the Sales Agreement will terminate upon the earlier of (i) the sale of all Common Stock subject to the Sales Agreement or (ii) termination of the Sales Agreement in accordance with its terms. As of December 31, 2020, the Company had not sold any shares under the Sales Agreement. Stock purchase agreement On December 17, 2018, the Company entered into a stock purchase agreement (the "Stock Purchase Agreement") with Lincoln Park Capital ("LPC"). Upon entering into the Stock Purchase Agreement, the Company sold 1,921,968 shares of common stock for $1.0 million to LPC, representing a premium of 110% to the previous day's closing price. As consideration for LPC’s commitment to purchase shares of common stock under the Stock Purchase Agreement, the Company issued 354,430 shares to LPC. The Company has the right at its sole discretion to sell to LPC up to $20.0 million worth of shares over a 36-month period subject to the terms of the Stock Purchase Agreement. The Company controls the timing of any sales to LPC and LPC will be obligated to make purchases of the Company's common stock upon receipt of requests from the Company in accordance with the terms of the Stock Purchase Agreement. There are no upper limits to the price per share LPC may pay to purchase up to $20.0 million worth of common stock subject to the Stock Purchase Agreement, and the purchase price of the shares will be based on the then prevailing market prices of the Company's shares at the time of each sale to LPC as described in the Stock Purchase Agreement, provided that LPC will not be obligated to make purchases of the Company's common stock pursuant to receipt of a request from the Company on any business day on which the last closing trade price of the Company's common stock on the NASDAQ Capital Market (or alternative national exchange in accordance with the Stock Purchase Agreement) is below a floor price of $0.25 per share. No warrants, derivatives, financial or business covenants are associated with the Stock Purchase Agreement and LPC has agreed not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of shares of the Company's common stock. The Stock Purchase Agreement may be terminated by the Company at any time, at the Company's sole discretion, without any cost or penalty. On August 5, 2020, the Company filed with the SEC a prospectus supplement, for the sale and issuance of up to $17.6 million of its common stock pursuant to the Stock Purchase Agreement dated December 17, 2018. As of December 31, 2020, the Company had sold 4,521,968 shares under the Stock Purchase Agreement resulting in proceeds of $3.4 million. Registered direct offering On September 23, 2020, the Company and a healthcare-focused institutional investor entered into a subscription agreement, pursuant to which the Company sold (i) 8,512,088 shares of its common stock and accompanying warrants to purchase up to 8,512,088 shares of common stock and (ii) pre-funded warrants to purchase up to 9,492,953 shares of common stock and accompanying warrants to purchase up to 9,492,953 shares of common stock in a registered direct offering for gross proceeds of approximately $17.3 million. The common stock (or pre-funded warrants in lieu thereof) and accompanying warrants were sold as units, each consisting of one share (or one pre-funded warrant to purchase one share of common stock in lieu thereof) and one warrant to purchase one share of common stock, at an offering price of $0.9581 per unit. The pre-funded warrants became exercisable immediately upon issuance, have an exercise price of $0.0001 per share and will be exercisable until all of the pre-funded warrants are exercised in full. The warrants became exercisable immediately upon issuance, have an exercise price of $0.8748 per share, and will expire five years from the date of issuance. The pre-funded warrants and the warrants each prohibit the holder from exercising any portion thereof to the extent that the holder would own more than 9.99% of the number of shares of common stock outstanding immediately after exercise. The number of shares issuable upon exercise of the warrants and pre-funded warrants and the exercise price of the warrants and pre-funded warrants is adjustable in the event of stock splits, stock dividends, combinations of shares and similar recapitalization transactions. The net proceeds to the Company from the offering, after deducting the placement agent's fees and other estimated offering expenses payable by the Company, was approximately $15.9 million. Warrants The Company has issued warrants to certain investors and consultants to purchase shares of the Company’s common stock. Based on the Company’s assessment of the warrants granted in 2013 and 2014 relative to ASC 480, Distinguishing Liabilities from Equity , such warrants are classified as equity. According to ASC 480, an entity shall classify as a liability any financial instrument, other than an outstanding share, that, at inception, both a) embodies an obligation to repurchase the issuer’s equity shares, or is indexed to such obligation and b) requires or may require the issuer to settle the obligation by transferring assets. The warrants do not contain any provision that requires the Company to repurchase the shares and are not indexed to such an obligation. The warrants also do not require the Company to settle by transferring assets. All warrants were exercisable immediately upon issuance. In connection with the September 23, 2020 registered direct offering, the Company issued 9,492,953 pre-funded common stock warrants with an exercise price of $0.0001 per share and an additional 18,005,041 common stock warrants with an exercise price of $0.8748 per share. All of the warrants are exercisable for one share of common stock and are exercisable immediately. As of March 3, 2021, approximately 6.0 million of the common stock warrants have been exercised. The pre-funded warrants are exercisable indefinitely, while the additional warrants are exercisable for 5 years from the date of issuance. As of December 31, 2020, all pre-funded warrants were exercised. Based on the Company’s assessment of the warrants granted relative to ASC 480, Distinguishing Liabilities from Equity and ASC 815-40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock, these warrants are classified as equity instruments. The fair value of the common stock warrants of approximately $10.2 million at the date of issuance was estimated using the Black-Scholes model which used the following inputs: term of 5 years, risk free rate of 0.28%, 0% dividend yield, volatility of 90.15%, an exercise price of $0.875 and share price of $0.833 per share based on the trading price of the Company’s common stock. Warrants to purchase 18,025,967 shares of common stock were outstanding as of December 31, 2020 and warrants to purchase 28,926 shares were outstanding as of December 31, 2019. Outstanding common stock warrants are currently exercisable with varying exercise expiration dates from 2024 through 2025, and outstanding pre-funded warrants are exercisable until all of the pre-funded warrants are exercised in full . As of December 31, 2020, all pre-funded warrants have been exercised. At December 31, 2020 and 2019, the weighted average warrant exercise price per share for common stock and pre-funded warrants underlying the warrants and the weighted average contractual life was as follows: Number of Common Stock Number of Pre-funded Weighted Weighted Average Remaining Contractual Life Number of Weighted Average Price Per Share Outstanding December 31, 2019 28,926 — $ 9.8 3.66 28,926 $ 9.8 Granted 18,005,041 — $ 0.88 4.73 18,005,041 $ 0.88 Granted- pre-funded warrants — 9,492,953 $ 0.0001 — 9,492,953 $ 0.0001 Exercised — (9,492,953) — — (9,492,953) — Cancelled/expired (8,000) — — — (8,000) — Outstanding December 31, 2020 18,025,967 — $ 0.89 4.73 18,025,967 $ 0.89 Stock option plans In June 2004, the Company authorized the adoption of the 2004 Stock Option and Incentive Plan (the “2004 Plan”). Under the 2004 Plan, options were granted to persons who were, at the time of grant, employees, officers, or directors of, or consultants or advisors to, the Company. The 2004 Plan provided for the granting of non-statutory options, incentive options, stock bonuses, and rights to acquire restricted stock. The option price at the date of grant was determined by the Board of Directors and, in the case of incentive options, could not be less than the fair market value of the common stock at the date of grant, as determined by the Board of Directors. Options granted under the 2004 Plan generally vest over a period of four years and are set to expire ten years from the date of grant. In February 2011, the Company terminated the 2004 Plan and all options outstanding under it were transferred to the 2011 Stock Option/Stock Issuance Plan (the “2011 Plan”). In February 2011, the Company authorized the adoption of the 2011 Plan. The 2011 Plan is divided into two separate equity programs, Option Grant Program and Stock Issuance Program. Per the 2011 Plan, options can be granted to persons who are, at the time, employees, officers, or directors of, or consultants or advisors to, the Company. The 2011 Plan provides for the granting of non-statutory options, incentive options and common stock. The price at the date of grant is determined by the Board of Directors and, in the case of incentive options and common stock, cannot be less than the fair market value of the common stock at the date of grant, as determined by the Board of Directors. Options granted under the 2011 Plan generally vest over a period of four years and expire ten years from the date of grant. In June 2015, the Company terminated the 2011 Plan and all options outstanding under it were transferred to the 2015 Stock Incentive Plan (the “2015 Plan”). The 2015 Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. The number of shares of our common stock that will be reserved for issuance under the 2015 Plan is the sum of: (1) 2,000,000; plus (2) the number of shares equal to the sum of the number of shares of our common stock then available for issuance under the 2011 Plan and the number of shares of our common stock subject to outstanding awards under the 2011 Plan or under the 2004 Plan that expire, terminate or are otherwise surrendered, canceled, forfeited or repurchased by us at their original issuance price pursuant to a contractual repurchase right; plus (3) an annual increase, to be added on the first day of each fiscal year, beginning with the fiscal year ending December 31, 2016 and continuing until, and including, the fiscal year ending December 31, 2025, equal to the least of (a) 3,000,000 shares of our common stock, (b) 3% of the number of shares of our common stock outstanding on the first day of such fiscal year and (c) an amount determined by the Board. Our employees, officers, directors, consultants and advisors will be eligible to receive awards under the 2015 Plan. Incentive stock options, however, may only be granted to our employees. Options and restricted stock awards granted under the 2015 Plan generally vest over a period of four years and expire ten years from the date of grant. Effective January 1, 2020, an additional 2,112,822 shares of the Company's common stock were added to the 2015 Plan under the terms of this provision. As of December 31, 2020, 275,439 shares of common stock were available for future issuance under the 2015 Plan. On April 29, 2019, the stockholders approved the Conformis, Inc. 2019 Sales Team Performance-Based Equity Incentive Plan ("2019 Sales Team Plan") for up to 3,000,000 shares of common stock available to grant to certain sales representatives or independent sales agents. The 2019 Sales Team Plan provides for the grant of performance-based equity, including incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. Shares covered by awards under the 2019 Sales Team Plan that expire or are terminated, surrendered, or cancelled without having been fully exercised or are forfeited in whole or in part (including as the result of shares subject to such award being repurchased by us at the original issuance price pursuant to a contractual repurchase right) or that result in any shares not being issued, will again be available for the grant of awards under the 2019 Sales Team Plan. Equity granted under the 2019 Sales Team Plan will expire ten years from the date of the grant. As of December 31, 2020, 2,771,481 shares of common stock were available for future issuance under the 2019 Sales Team Plan.

The weighted average remaining contractual term for the total stock options vested and exercisable was 3.97 years at December 31, 2020. Restricted common stock award activity under the plans was as follows: Number of Shares Weighted Average Fair Value Unvested December 31, 2018 2,473,372 $ 2.45 Granted 4,405,424 1.09 Vested (1,231,541) 2.14 Forfeited (1,210,327) 1.15 Unvested December 31, 2019 4,436,928 $ 1.54 Granted 4,351,758 0.95 Vested (1,882,094) 1.56 Forfeited (630,553) 1.01 Unvested December 31, 2020 6,276,039 $ 1.18 The total fair value of restricted common stock awards that vested during the year ended December 31, 2020 was $2.9 million. Inducement Awards In February 2020, the Company granted inducement awards outside of the 2015 Plan and 2019 Sales Team Plan (i) to the Company's Chief Financial Officer in the form of an option to purchase 125,000 shares of the Company's common stock with an exercise price per share equal to $0.98 and 125,000 restricted stock units and (ii) to the Company's Senior Vice President, Operations in the form of an option to purchase 66,667 shares of the Company's common stock with an exercise price per share equal to $0.98 and 61,350 restricted stock units. The option and restricted stock unit awards were granted as inducements material to their commencement of employment with the Company in accordance with NASDAQ Listing Rule 5635(c)(4). In August 2020, the Company granted inducement awards outside of the 2015 Plan and 2019 Sales Team Plan to the Company's Vice President, US Marketing in the form of an option to purchase 100,000 shares of the Company's common stock with an exercise price per share equal to $0.7427 and 100,000 restricted stock units. The option and restricted stock unit awards were granted as inducements material to his commencement of employment with the Company in accordance with NASDAQ Listing Rule 5635(c)(4). In November 2020, the Company granted inducement awards outside of the 2015 Plan and 2019 Sales Team Plan to the Company's Vice President, International Sales and Marketing in the form of 75,000 restricted stock units. The restricted stock unit awards were granted as inducements material to his commencement of employment with the Company in accordance with NASDAQ Listing Rule 5635(c)(4). Stock-based compensation The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. The determination of the fair value of stock-based payment awards on the date of grant using a pricing model is affected by the value of the Company’s common stock as well as assumptions regarding a number of complex and subjective variables. The valuation of the Company’s common stock prior to its initial public offering was performed with the assistance of an independent third-party valuation firm using a methodology that includes various inputs including the Company’s historical and projected financial results, peer company public data and market metrics, such as risk-free interest and discount rates. As the valuations included unobservable inputs that were primarily based on the Company’s own assumptions, the inputs were considered level 3 inputs within the fair value hierarchy. The fair value for restricted stock awards and performance awards is the grant date close price of the Company's Common Stock as reported by NASDAQ. The weighted average fair value of options granted was $0.47 and $1.44 for the year ended December 31, 2020 and 2019, respectively. The fair value of options at date of grant was estimated using the Black-Scholes option pricing model, based on the following assumptions: Years Ended December 31, 2020 2019 Risk-free interest rate 1.14% 1.89% Expected term (in years) 6.16 6.00 Dividend yield —% —% Expected volatility 54.89% 55.80% Risk-free interest rate . The risk-free interest rate is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options. Expected term. The expected term of stock options represents the period the stock options are expected to remain outstanding and is based on the “SEC Shortcut Approach” as defined in “Share-Based Payment” (SAB 107) ASC 718-10-S99, “Compensation-Stock Compensation-Overall-SEC Materials,” which is the midpoint between the vesting date and the end of the contractual term. With certain stock option grants, the exercise price may exceed the fair value of the common stock. In these instances, the Company adjusts the expected term accordingly. Dividend yield. The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model. Expected volatility. Expected volatility measures the amount that a stock price has fluctuated or is expected to fluctuate during a period. The Company has limited history of market prices of its common stock over the historical period equal in length to the expected term, and may sometimes estimate volatility using historical volatilities of similar public entities. Forfeitures. The Company recognizes forfeitures as they occur. Stock-based compensation expense was $3.4 million and $2.8 million for the years ended December 31, 2020 and 2019, respectively. Stock-based compensation expense was recognized ratably over the period with forfeitures accounted for in the period in which they occurred. To date, the amount of stock-based compensation capitalized as part of inventory was not material. The following is a summary of stock-based compensation expense (in thousands): Years Ended December 31, 2020 2019 Cost of revenue $ 72 $ 350 Sales and marketing 446 213 Research and development 648 565 General and administrative 2,240 1,709 $ 3,406 $ 2,837 |
