Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (this “Report”) of Solid Power, Inc. (f/k/a Decarbonization Plus Acquisition Corporation III, “Solid Power,” the “Company,” “we,” “us,” or “our”) contains forward-looking statements, within the meaning of the Private Securities Litigation Reform Act of 1995, that involve risks and uncertainties. We have based these forward-looking statements on our current expectations and projections about future events. All statements, other than statements of present or historical fact included in this Report, regarding our future financial performance and our strategy, expansion plans, market opportunity, future operations, future operating results, estimated revenues, losses, projected costs, prospects, plans and objectives of management are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may,” “should,” “could,” “would,” “will,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “continue,” “project” or the negative of such terms or other similar expressions. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this Report. We caution you that the forward-looking statements contained herein are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control.

In addition, we caution you that the forward-looking statements regarding the Company contained in this Report are subject to the following factors:

● risks relating to the uncertainty of the success of our research and development efforts, including our ability to achieve the technological objectives or results that our partners require, and to commercialize our technology in advance of competing technologies;
● risks relating to the non-exclusive nature of our original equipment manufacturer and joint development agreement relationships;
● our ability to negotiate and execute supply agreements with our partners on commercially reasonable terms;
● our ability to protect our intellectual property, including in jurisdictions outside of the United States;
● broad market adoption of electric vehicles and other technologies where we are able to deploy our all-solid-state batteries, if developed successfully;
● our success in retaining or recruiting, or changes required in, our officers, key employees, including technicians and engineers, or directors;
● changes in applicable laws or regulations;
● risks related to technology systems and security breaches;
● the possibility that COVID-19 or a future pandemic may adversely affect our results of operations, financial position and cash flows;
● the possibility that we may be adversely affected by other economic, business or competitive factors, including supply chain interruptions, and may not be able to manage other risks and uncertainties;
● risks relating to our status as an early stage company with a history of financial losses, and an expectation to incur significant expenses and continuing losses for the foreseeable future;
● rollout of our business plan and the timing of expected business milestones;
● the termination or reduction of government clean energy and electric vehicle incentives;
● delays in the construction and operation of production facilities;

1

● changes in domestic and foreign business, market, financial, political and legal conditions; and
● those factors discussed in “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021.

We caution you that the foregoing list does not contain all of the risks or uncertainties that could affect the Company.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Report primarily on our current expectations and projections about future events and trends that we believe may affect our business, operating results, financial condition and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties and other factors, including those described in “Part I, Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Report. We cannot assure you that the results, events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events or circumstances could differ materially from those described in the forward-looking statements.

Neither we nor any other person assumes responsibility for the accuracy and completeness of any of these forward-looking statements. Moreover, the forward-looking statements made in this Report relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Report to reflect events or circumstances after the date of this Report or to reflect new information or the occurrence of unanticipated events, except as required by law. You should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures or investments we may make.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 – Nature of Business

Solid Power, Inc. (the “Company”), headquartered in Louisville, Colorado, is developing all-solid-state battery cell technology primarily for the electric vehicle market. The Company’s planned business model is to license its all-solid-state battery cell designs and manufacturing know-how to top tier battery manufacturers or automotive original equipment manufacturers and to sell its sulfide-based solid electrolyte for incorporation into all-solid-state battery cells. As of September 30, 2022, the Company has not derived material revenue from its principal business activities.

On December 8, 2021 (the “Closing Date”), the Company (f/k/a Decarbonization Plus Acquisition Corporation III (“DCRC”)) consummated its business combination pursuant to the Business Combination Agreement and Plan of Reorganization, dated June 15, 2021 (as amended, the “Business Combination Agreement”), among the Company, DCRC Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of DCRC (“Merger Sub”), and Solid Power Operating, Inc., a Colorado corporation (f/k/a Solid Power, Inc., “Legacy Solid Power”). Pursuant to the terms of the Business Combination Agreement, Merger Sub merged with and into Legacy Solid Power, with Legacy Solid Power surviving the merger as a wholly owned subsidiary of the Company (the “Merger” and, together with the other transactions contemplated by the Business Combination Agreement, the “Business Combination”).

Pursuant to the Business Combination Agreement, the Merger was accounted for as a reverse recapitalization (the “Reverse Recapitalization”) in accordance with generally accepted accounting principles in the United States (“GAAP”). Under this method of accounting, DCRC was treated as the “acquired” company and Legacy Solid Power is treated as the acquirer for financial reporting purposes. See Note 3.

Note 2 – Significant Accounting Policies

The significant accounting policies followed by the Company are set forth in Note 2 – Significant Accounting Policies to the Company’s financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”) and are supplemented by the Notes to the Condensed Consolidated Financial Statements (Unaudited) (the “Notes”) included in this Quarterly Report on Form 10-Q for the period ended September 30, 2022 (this “Report”). The financial statements included in this Report (including the Notes) should be read in conjunction with the 2021 Form 10-K.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared on the basis of GAAP. The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the unaudited condensed consolidated financial statements. Actual results could differ from those estimates. All dollar amounts presented herein are in U.S. dollars and are in thousands, except par value, share and per share amounts.

The accompanying unaudited condensed consolidated financial statements include accounts of the Company and its wholly owned subsidiary, Solid Power Operating, Inc. All intercompany balances and transactions have been eliminated in consolidation.

Long-Term Investments

The Company considers all investments with an original maturity of twelve months or more when purchased to be long-term investments.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents, marketable securities, and long-term investments. The Company seeks to mitigate its credit risk with respect to cash and cash equivalents, marketable securities, and long-term investments by making deposits with several large, reputable financial institutions and investing in high credit rated instruments. See Note 8 for allocation of respective investment holdings.

7

Leases

The Company accounts for its leases under ASU No. 2016-02, Leases (Topic 842). Under this guidance, the Company classifies contracts meeting the definition of a lease as operating or financing leases, and leases are recorded on the condensed consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease or the Company’s incremental borrowing rate. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term. For finance leases, interest on the lease liability and the amortization of the right-of-use asset results in front-loaded expense over the lease term. Variable lease expenses, including common maintenance fees, insurance and property tax, are recorded when incurred.

In calculating the right-of-use asset and lease liability, the Company elects to combine lease and non-lease components for all classes of assets. The Company excludes short-term leases having initial terms of 12 months or less as an accounting policy election, and instead recognizes rent expense on a straight-line basis over the lease term.

Recent Accounting Pronouncements

Leases

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), followed by other related ASUs that provided targeted improvements and additional practical expedient options. On January 1, 2022, the Company adopted the standards under Topic 842 using the modified retrospective method and elected a number of the practical expedients in its implementation of Topic 842. The key change that affected the Company relates to accounting for operating leases for which it is the lessee that were historically off-balance sheet. The impact of adopting the standards resulted in the recognition of a right-of-use asset of $7,853 and lease liability of $8,246 on the Company’s condensed consolidated balance sheet on January 1, 2022, exclusive of previously recognized lease balances. The implementation of Topic 842 did not have a material effect on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows for the nine months ended September 30, 2022.

Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments- Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This guidance introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected credit losses. ASU 2016-13 also provides updated guidance regarding the impairment of available-for-sale debt securities and includes additional disclosure requirements. The Company adopted this guidance as of January 1, 2022.

The Company regularly reviews its available-for-sale marketable securities and evaluates the current expected credit losses by considering factors such as any changes in credit ratings, historical experience, market data, issuer-specific factors, and current economic conditions. Based on this analysis, an allowance for credit losses is recorded as a reduction to the carrying value of the asset.

The Company reviews its receivable aging on an individual customer level, considering collectability of cash flows based on the risk of past events, current conditions, and forward-looking information. The Company establishes allowances for bad debts equal to the estimable portions of accounts receivable for which failure to collect is expected to occur. Allowances for doubtful accounts are recorded as reductions to the carrying values of the related receivables.

Income Taxes

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which aims to reduce complexity in accounting standards by improving certain areas of GAAP without compromising information provided to users of financial statements. ASU 2019-12 is effective for public entities for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. For all other entities, the standard is effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company adopted this guidance beginning January 1, 2022 with no financial statement impact at adoption.

Note 3 – Business Combination

Legacy Solid Power was deemed the accounting acquirer in the Business Combination based on the analysis of the criteria outlined in FASB Topic 805, Business Combinations. Accordingly, for accounting purposes, the Business Combination was treated as the equivalent of Legacy Solid Power issuing stock for the net assets of DCRC, accompanied by a recapitalization. The net assets of DCRC are stated at historical cost, with no goodwill or other intangible assets recorded.

8

Because Legacy Solid Power was deemed the accounting acquirer, the historical consolidated financial statements of Legacy Solid Power became the historical consolidated financial statements of the combined company. As a result, the condensed consolidated financial statements included in this Report reflect (i) the historical operating results of Legacy Solid Power prior to the Business Combination; (ii) the combined results of the Company and Legacy Solid Power following the closing of the Business Combination (“Closing”); (iii) the assets and liabilities of Legacy Solid Power at their historical cost; and (iv) the Company’s equity structure for all periods presented as discussed below.

In accordance with guidance applicable to the Business Combination, the equity structure has been restated in all comparative periods up to the Closing Date, to reflect the number of shares of the Company’s common stock, $0.0001 par value per share, issued to Legacy Solid Power’s stockholders in connection with the Business Combination. As such, the shares and corresponding capital amounts and earnings per share related to Legacy Solid Power redeemable convertible preferred stock and common stock prior to the Business Combination have been retroactively restated to reflect an exchange ratio of approximately 3.182 (the “Exchange Ratio”). Activity within the condensed consolidated statements of stockholders’ equity for the issuances and repurchases of Legacy Solid Power’s redeemable convertible preferred stock were also retroactively converted to Legacy Solid Power common stock.

In 2022, the Company expanded its cell production capabilities through the construction of a second dry room and installation of a second EV cell pilot line at its Louisville, Colorado facility, which is designed to produce larger format all-solid-state battery cells for the automotive qualification process. Construction in progress related to these efforts was $2,010 and $6,875 as of September 30, 2022 and December 31, 2021, respectively. Construction in progress related to multiple other projects at the Louisville, Colorado facility was $1,521 as of September 30, 2022.

The Company is expanding its sulfide-based solid electrolyte production to a second location in Thornton, Colorado. Scaling this production will allow it to produce larger quantities of electrolyte material required to feed the cell-production lines and continue research and development efforts. The Company expects to begin producing sulfide-based electrolyte from this facility in the first quarter of 2023. Construction in progress related to these efforts was $46,435 and $5,809 as of September 30, 2022 and December 31, 2021, respectively.

Note Payable

On December 7, 2021, prior to the Closing, the Company used available cash to pay off the outstanding balance and remaining fees of a note payable to a commercial bank. The Company was in compliance with all financial covenants through the loan payoff on December 7, 2021.

Interest expense on long-term debt was $1 and $32 for the three months ended September 30, 2022 and 2021, respectively, and $6 and $111 for the nine months ended September 30, 2022 and 2021, respectively.

Note 7 – Convertible Notes Payable

2020 Convertible Promissory Notes

On December 10, 2020 and December 18, 2020, the Company issued unsecured convertible promissory notes to investors in the total principal amount of $5,125, and on February 4, 2021, and March 1, 2021, the Company issued additional unsecured convertible promissory notes to investors in the total principal amount of $4,875, as part of a single financing (collectively, the “2020 Notes”). The 2020 Notes accrued interest at eight percent per annum. The 2020 Notes were converted into 1,007,965 shares of Legacy Solid Power Series B Preferred Stock, on May 5, 2021, in conjunction with the closing of the Legacy Solid Power Series B Preferred Stock (“Series B Financing”). The outstanding balance on the 2020 Notes, including accrued interest, was $10,228 when the 2020 Notes were converted to Legacy Solid Power Series B Preferred Stock. Interest expense for the 2020 Notes for three and nine months ended September 30, 2021 was $0 and $210, respectively. The principal of the 2020 Notes was included in Additional Paid In Capital

10

and the fair value of the embedded derivative was recorded as a liability on Legacy Solid Power’s balance sheet. The fair value of the embedded derivative was $5,497. This balance was transferred, along with the accrued interest, to mezzanine equity upon conversion of the 2020 Notes to Series B Preferred Stock in conjunction with the Series B Financing.

2020 Convertible Promissory Notes Embedded Derivative

The 2020 Notes contained the following embedded derivatives: (i) a share settled redemption upon Qualified Financing; (ii) share settled redemption upon the closing of the Business Combination; and (iii) share settled redemption at maturity.

Embedded derivatives are separated from the host contract and carried at fair value when: (a) the embedded derivative possesses economic characteristics that are not clearly and closely related to the economic characteristics of the host contract; and (b) a separate, stand-alone instrument with the same terms would qualify as a derivative instrument. The Company has concluded that certain embedded derivatives within the 2020 Notes meet these criteria and, as such, must be valued separate and apart from the 2020 convertible promissory notes as one embedded derivative and recorded at fair value each reporting period.

See Note 8 – Fair Value Measurement for information about the assumptions that the Company used to measure the fair value of the embedded derivative.

2019 Convertible Promissory Notes

On December 4, 2019, the Company issued an unsecured convertible promissory note to an investor in the principal amount of $3,000 (the “2019 Note,” and together with the 2020 Notes, the “Convertible Promissory Notes”). The 2019 Note accrued interest at 5 percent per annum. The 2019 Note converted into 254,899 shares of Legacy Solid Power Series B Preferred Stock, in conjunction with the Series B Financing. Upon this conversion, the 2019 Note converted to Series B Preferred Stock at a 30 percent discount.

See Note 8 – Fair Value Measurement for information about the assumptions that the Company used to measure the fair value of the 2019 Note. At December 31, 2020, the outstanding balance on the 2019 Note was $3,612. For the three and nine months ended September 30, 2021, interest expense of $0 and $53, respectively, was incurred related to the 2019 Note.

For all debt instruments, including any for which the Company has elected fair value accounting, the Company classifies interest that has been accrued during each period as Interest expense on the Condensed Consolidated Statements of Operations.

Note 8 – Fair Value Measurements

The carrying amounts of certain financial instruments, such as cash equivalents, short-term investments, accounts receivable, accounts payable, accrued liabilities, and equipment notes payable approximate fair value due to their short maturities.

The fair value of debt instruments for which the Company has not elected fair value accounting is based on the present value of expected future cash flows and assumptions about the then-current market interest rates as of the reporting period and the creditworthiness of the Company. The book values of the Company’s long-term debt approximate fair value because interest rates charged are similar to other financial instruments with similar terms and maturities and the rates vary in accordance with a market index. Most of the Company’s debt is carried on the condensed consolidated balance sheets on a historical cost basis net of unamortized discounts and premiums because the Company has not elected the fair value option of accounting. Changes to the inputs used in these valuation models can have a significant impact on the estimated fair value of the Convertible Promissory Notes and the Company’s embedded derivatives.

11

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

As discussed in Note 7, all Convertible Promissory Notes were converted to Legacy Solid Power Series B Preferred Stock in May 2021. As of September 30, 2022 and December 31, 2021 the Company’s financial liabilities measured and recorded at fair value on a recurring basis were classified within the fair value hierarchy as follows:

The change in fair value of the Company’s marketable securities is included in Other Comprehensive loss. There were no transfers in and out of Level 3 fair value hierarchy during the three or nine months ended September 30, 2022 and 2021.

Fair Value of Stock Warrants

The fair value of the Private Placement Warrants (defined below) has been estimated using a Black-Scholes model as of September 30, 2022 and December 31, 2021. The fair value of the Public Warrants (defined below) has been measured based on the quoted price of such warrants on the Nasdaq Stock Market, a level 1 input. The estimated fair value of the Private Placement Warrants is determined using Level 2 inputs. Inherent in a Black-Scholes model are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. Material increases (or decreases) in any of those inputs may result in a significantly higher (or lower) fair value measurement. The Company estimates the volatility of its Private Placement Warrants based on implied volatility from the Company’s Public Warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend yield is based on the historical rate, which the Company anticipates remaining at zero. Refer to Note 9 for additional details on the Company’s warrant liabilities.

Note 9 – Common Stock Warrant Liabilities

As of September 30, 2022 and December 31, 2021, there were 11,666,636 publicly traded warrants (“Public Warrants”) and 7,666,667 private placement warrants (“Private Placement Warrants,” and together with the Public Warrants, “Warrants”) outstanding. Each whole Warrant entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to customary adjustments. Only whole Warrants are exercisable. The Warrants became exercisable on January 7, 2022 and will expire on December 8, 2026.

Redemption of Public Warrants when the price per share of Common Stock equals or exceeds $18.00.

The Company may redeem all of the outstanding Public Warrants:

● in whole and not in part;
● upon at least 30 days’ prior written notice;
● at a price of $0.01 per Public Warrant; and
● if the last sale price of the Company’s Common Stock equals or exceeds $18.00 per share, subject to customary adjustments, for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which notice of the redemption is given.

Redemption of Public Warrants when the price per share of Common Stock equals or exceeds $10.00.

The Company may redeem all of the outstanding Public Warrants:

● in whole and not in part;
● upon at least 30 days’ prior written notice;

13

● at a price of $0.10 per Public Warrant, provided that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive a number of shares of Common Stock determined in part by the redemption date and the “fair market value” of the Common Stock; and
● if the last sale price of the Company’s Common Stock equals or exceeds $10.00 per share, subject to customary adjustments, on the trading day prior to the date on which notice of redemption is given.

The “fair market value” of the Company’s Common Stock means the average reported last sale price of the Company’s Common Stock for the ten trading days immediately following the date on which the notice of redemption is sent to the holders of Warrants. The Company classifies the outstanding Warrants as Warrant Liabilities on the condensed consolidated balance sheets in accordance with the guidance contained in ASC 815.

None of the Private Placement Warrants are redeemable by the Company so long as they are held by the initial purchasers of the Private Placement Warrants or their permitted transferees.

The warrant liabilities were initially measured at fair value upon Closing of the Business Combination and subsequently re-measured at each reporting period. The Public Warrants were allocated a portion of the proceeds from the issuance of the Units equal to its fair value. The Company recognized a gain in connection with changes in the fair value of warrant liabilities of $0 and $28,183 for the three- and nine-months ending September 30, 2022, respectively.

Note 10 – Mezzanine Equity

In accordance with ASC 480, Legacy Solid Power’s Series A-1 Preferred Stock and Series B Preferred Stock (collectively, “Preferred Stock”) prior to the Business Combination were classified as mezzanine equity. Immediately prior to the Closing Legacy Solid Power had 14,069,187 shares of Series A-1 Preferred Stock outstanding and 8,777,812 shares of Series B Preferred Stock outstanding. Legacy Solid Power issued the Series B Preferred Stock in May 2021 in exchange for $135,579 of cash and the conversion of the 2019 Note and the 2020 Notes as discussed in Note 7. See Note 11 for a discussion of warrants issued with the Legacy Solid Power Series B Preferred Stock.

Prior to the Business Combination, the Preferred Stock had a redemption feature, at the option of the holders of a majority of the outstanding Preferred Stock, any time after April 30, 2031. The Preferred Stock was redeemable for the greater of its original issue price, plus all declared but unpaid dividends thereon, or fair value. Since the Preferred Stock had redemption provisions that were not solely within control of Legacy Solid Power, the Preferred Stock was classified prior to the Business Combination as mezzanine equity on Legacy Solid Power’s balance sheets.

As a result of the Business Combination with DCRC on December 8, 2021, the Solid Power Series A-1 and Series B Preferred Stock converted to common stock. The 14,069,187 and 8,777,812 shares of Series A-1 Preferred Stock and Series B Preferred Stock were converted to the equivalent number of shares of Legacy Solid Power common stock prior to the impact of the common stock Exchange Ratio used to complete the Business Combination.

Legacy Solid Power Warrants

During 2015, Legacy Solid Power issued warrants to a third party to purchase 276,000 shares of Legacy Solid Power common stock at an exercise price of $0.00001088 per share, in conjunction with a licensing agreement. Management determined that equity classification is appropriate for these warrants. Legacy Solid Power recognized expense totaling $18 on the date of the grant that has been included as a component of Additional Paid In Capital within the condensed consolidated statement of stockholders’ equity. During 2020, Legacy Solid Power issued additional warrants to purchase 45,730 shares of common stock at an exercise price of $0.53 per share. Legacy Solid Power recognized expense totaling $16 on the date of the grant.

In May 2021, Legacy Solid Power issued warrants to purchase 1,755,557 shares of Legacy Solid Power common stock at an exercise price of $0.01 per share, in connection with the Series B Financing. These warrants were detachable from the Legacy Solid Power Series B Preferred Stock and in all cases would physically settle or net share settle. Therefore, Legacy Solid Power determined that these warrants represented equity in Legacy Solid Power. Prior to the Closing, all Legacy Solid Power warrants were either exercised for cash or net exercised and the holders thereof received shares of Legacy Solid Power common stock.

Note 12 – Stock Based Compensation

2014 Equity Incentive Plan and 2021 Equity Incentive Plan

At September 30, 2022, the Company had 25,827,919 shares of common stock underlying stock options outstanding under the 2014 Plan. Upon the Closing, the 2014 Plan was terminated and no additional grants will be made under the 2014 Plan.

On December 8, 2021 and in connection with the Closing, the Company adopted the Solid Power, Inc. 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan originated with 18,900,000 shares of Common Stock available for issuance. Beginning on January 1, 2022, the number of shares of common stock available for issuance under the 2021 Plan shall increase each year by an amount equal to the lesser of (i) 18,900,000 shares of Common Stock (ii) five percent of the total number of shares of common stock outstanding on the last day of the immediately preceding fiscal year; or (iii) a number of shares of common stock determined by the administrator no later than the last day of the immediately preceding fiscal year.

As of September 30, 2022, the 2021 Plan permitted the Company to grant up to 24,821,940 shares of common stock to its employees, directors, and consultants, as designated by the board of directors. Awards may be issued in the form of stock options, stock appreciation rights, restricted stock, and restricted stock units. The Company believes that such awards better align the interests of its employees with those of its stockholders.

The fair value of stock options and restricted stock units (“RSUs”) issued to employees and directors is recognized as compensation expense over the period of service that generally coincides with the vesting period of the award. When calculating the amount of annual compensation expense, the Company has elected not to estimate forfeitures and instead accounts for forfeitures as they occur.

For the three months and nine months ended September 30, 2022, the Company recognized compensation costs totaling:

Stock Options

Options granted under the 2014 Plan generally had a ten-year term and vest as to 1/4th of these shares after one year after the initial date of service of a service provider and with the balance of the shares vesting in a series of 36 successive equal monthly installments following the first vesting date. Option awards under the 2014 Plan were generally granted with an exercise price equal to the fair market value of Legacy Solid Power’s common stock at the date of grant. Certain option awards issued under the 2014 Plan provide for accelerated vesting if there is a change in control (as defined in the plan agreements).

Options granted under the 2021 Plan generally have a ten-year term and vest as to 1/4th of these shares each year, commencing after one year after the initial date of grant. Option awards under the 2021 Plan are generally granted with an exercise price equal to the fair market value of Solid Power’s common stock at the date of grant. Certain option awards issued under the 2021 Plan provide for accelerated vesting if there is a change in control (as defined in the plan agreements).

The fair value for purposes of determining the compensation cost of each option award is estimated on the date of grant using a Black-Scholes option valuation model that uses the weighted-average assumptions noted in the following table. Expected volatilities are based on historical volatility of comparable companies. The Company uses historical data to estimate option exercise and employee termination within the valuation model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The fair value of each option grant during the nine months ended September 30, 2022 and 2021 was estimated on the grant date using the Black-Scholes option pricing model with the following weighted-average assumptions used:
