Cautionary Note Regarding Forward-Looking Statements

This Report 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 or 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 and potential disruptions related to management and board of directors transitions;

● changes in applicable laws or regulations;

● risks related to technology systems and security breaches;

● 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 a research and development stage company with a history of financial losses, and an expectation to incur significant expenses and continuing losses for the foreseeable future;

● the termination or reduction of government clean energy and electric vehicle incentives;

● changes in domestic and foreign business, market, financial, political, and legal conditions; and

Risk Factors” in our 2022 Form 10-K and “Part II, Item 1A. Risk Factors” in our Q1 Form 10-Q, as such descriptions may be updated or amended in future filings we make with the SEC. Moreover, we operate in a very competitive and rapidly changing environment.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1 – Nature of Business

Solid Power, Inc. (the “Company”) is developing solid state battery technology to enable the next generation of batteries for the fast-growing EV and other markets. The Company’s planned business model is to sell its sulfide-based solid electrolyte and to license its solid-state cell designs and manufacturing process.

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, 2022 (the “2022 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, 2023 (this “Report”). The financial statements included in this Report (including the Notes) should be read in conjunction with the 2022 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 generally accepted accounting principles in the United States (“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 and share and per share amounts.

The accompanying unaudited condensed consolidated financial statements include accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Additionally, certain prior period amounts have been reclassified to conform to current period presentation in the accompanying unaudited condensed consolidated financial statements.

Recent Accounting Pronouncements

Leases

In February 2016, the FASB issued ASU 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. The key change that affected the Company relates to lessee accounting for operating leases that were historically off-balance sheet.

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 estimates of expected 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 changes in credit ratings, historical experience, market data, issuer-specific factors, and current economic conditions. Based on this analysis, any allowance for credit losses is immaterial but would otherwise be 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 it expects not to collect. Allowances for doubtful accounts are recorded as reductions to the carrying values of the related receivables. To date, the Company has not recorded an allowance for doubtful accounts.

The Company expanded its cell production capabilities through the construction of a second dry room and installation of an EV cell pilot line at its Louisville, Colorado facility, which is designed to produce larger format solid-state battery cells for the automotive qualification process.

The Company expanded its electrolyte production at its facility in Thornton, Colorado. Scaling this production will allow it to produce larger quantities of electrolyte material required to feed cell-production lines and continue research and development efforts. The Company began producing electrolyte at this facility in 2023 and has placed portions of the facility into service.

Note 5 – Fair Value Measurements

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

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

As of September 30, 2023 and December 31, 2022, the Company’s financial assets and liabilities measured and recorded at fair value on a recurring basis were classified within the fair value hierarchy as follows:

	September 30, 2023

The change in fair value of the Company’s marketable securities and long-term investments are included in other comprehensive income (loss). There were no transfers in and out of Level 3 fair value hierarchy during the nine months ended September 30, 2023 or year ended December 31, 2022. During the nine months ended September 30, 2023 and 2022, the Company purchased $256,584 and $448,757 of marketable securities and long-term investments, respectively.

Fair Value of Warrants

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 directly observable input. The fair value of the Private Placement Warrants (defined below) has been estimated using a Black-Scholes model as of September 30, 2023 and December 31, 2022 Consolidated Balance Sheet dates. The estimated fair value of the Private Placement Warrants is determined using Level 2 directly or indirectly observable inputs. Assumptions related to expected stock-price volatility, expected life, risk-free interest rate, and dividend yield are inherent in a Black-Scholes model. 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 companies’ common stock that matches the expected remaining life of the

12

Warrants (defined below). The expected life of the Warrants is assumed to be equivalent to their remaining contractual term. 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 dividend yield is based on the historical rate, which the Company anticipates remaining at zero. The following table provides quantitative information regarding Level 2 inputs used in the recurring valuation of the Private Placement Warrants as of their measurement dates:

	September 30, 2023			December 31, 2022
Exercise price	$	11.50		$	11.50
Stock price	$	2.02		$	2.54
Volatility		81.8	%		71.3	%
Term (years)		3.19			3.94
Risk-free rate		4.67	%		4.03	%

The following table provides a reconciliation of the Public Warrants measured at fair value using Level 1 inputs and Private Placement Warrants measured at fair value using Level 2 inputs:

	Public Warrants		Private Placement Warrants
	Level 1 Fair Value		Level 2 Fair Value
December 31, 2022	$	0.42	$	0.55
Change in fair value	$	0.04	$	0.31

Note 6 – Warrant Liabilities

As of September 30, 2023 and December 31, 2022, there were 12,684,423 and 11,666,636 publicly traded warrants (“Public Warrants”) and 6,648,880 and 7,666,667 private placement warrants (“Private Placement Warrants,” and together with the Public Warrants, “Warrants”) outstanding, respectively. 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.

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 Warrants were initially measured at fair value upon closing of the transactions contemplated by the Business Combination Agreement and Plan of Reorganization, dated June 15, 2021, by and among the Company, DCRC Merger Sub, Inc., and Solid Power Operating, Inc., as amended, for $101,253 and subsequently re-measured at each reporting period. The Public Warrants were allocated a portion of the proceeds from the issuance of the units of common stock and one-third warrants in the Company’s initial public offering equal to their fair value. The Company recognized a gain in connection with changes in the fair value of warrant

13

liabilities of $1,155 and $3,480 for the three and nine months ended September 30, 2023 and $0 and $28,183 for the three and nine months ended September 30, 2022, respectively.

There have been no changes to our Public or Private Placement Warrants, including redemption terms disclosed in our 2022 Form 10-K.

Note 7 – Stockholders’ Equity

Common Stock

Stock options exercised for common stock, shares of common stock issued under the Solid Power, Inc. 2021 Employee Stock Purchase Plan (“ESPP”), and shares of common stock issued upon vesting of restricted stock units (“RSUs”) for the three and nine months ended September 30, 2023 and 2022 are summarized in the table below:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2023	2022	2023	2022
Stock options exercised	58,065	1,293,762	2,084,695	8,162,906

Cash received from stock options exercised under the Solid Power, Inc. 2014 Equity Incentive Plan (the “2014 Plan”) for the three months ended September 30, 2023 and 2022 was $11 and $417, respectively. Cash received from stock options exercised under the 2014 Plan for the nine months ended September 30, 2023 and 2022 was $194 and $771, respectively.

Cash received from shares of common stock issued under the ESPP for the three months ended September 30, 2023 and 2022 was $0. Cash received from shares of common stock issued under the ESPP for the nine months ended September 30, 2023 and 2022 was $214 and $0, respectively.

Note 8 – Stock-Based Compensation

There have been no changes to our equity incentive plans, the ESPP, or our accounting methodology for stock-based compensation, as disclosed in our 2022 Form 10-K.

The fair value of stock options and 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. The Company allocated compensation ratably across Operating Expenses based on Company personnel costs incurred. 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 and nine months ended September 30, 2023, the Company recognized compensation costs totaling:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Equity-based compensation costs related to RSUs	$	1,248	$	618	$	2,839	$	1,133
Equity-based compensation costs related to stock options		2,012		1,970		5,486		5,365

Note 9 – Basic and Diluted Loss Per Share

Basic loss per share represents net loss attributable to common stock divided by the basic weighted average number of common stock outstanding during the period.

Due to the net loss for the three and nine months ended September 30, 2023 and 2022, diluted loss per share was computed without consideration to potentially dilutive instruments as their inclusion would have been anti-dilutive.

The table below sets forth the basic and diluted loss per share calculation for the three and nine months ended September 30, 2023 and 2022.

	Three Months Ended September 30,				Nine Months Ended September 30,

Note 10 – Leases

The Company leases its facilities and certain equipment. Fixed rent escalates each year, and the Company is responsible for a portion of the landlords’ operating expenses such as property tax, insurance, and common area maintenance.

The Company’s facility in Louisville, Colorado, is under a noncancelable operating lease with a maturity date in September 2029. In 2022, the Company amended this operating lease to incorporate a prior subleased space into the base lease and extend the term of the lease. The Company has the right to renew this operating lease for an additional five-year period.

On September 1, 2021, the Company entered into an industrial operating lease agreement for its facility in Thornton, Colorado, with the initial term through March 31, 2029. Under this operating lease, the Company has one option to renew for five years, which has been included in the calculation of lease liabilities and right-of-use assets at the adoption date of the lease accounting standard on January 1, 2022, as the exercise of the option was reasonably certain. As the renewal rent has not been negotiated, the Company used an estimated rent rate which approximated the fair market rent at adoption of ASC 842 on January 1, 2022 for the extension period.

The Company has certain equipment leases classified as finance leases as of September 30, 2023, as presented on the Balance Sheet.

The Company’s leases do not have any contingent rent payments and do not contain residual value guarantees.

The components of lease expense are as follows:

	Three Months Ended		Nine Months Ended
	September 30, 2023		September 30, 2023
Finance lease costs:
Amortization of right-of-use assets	$	50	$	141

Note 11 – Related Party Transactions

During the three and nine months ended September 30, 2023, the Company recognized $3,657 and $10,128, respectively, of revenue related to the BMW joint development agreement. As of September 30, 2023, the Company recorded $5,048 of accounts receivable related to the BMW joint development agreement.

Note 12 – Income Taxes

The Company’s effective tax rate was 0.00% and 0.68% for the three months ended September 30, 2023 and 2022, respectively, and 0.00% and 0.78% for the nine months ended September 30, 2023 and 2022, respectively. The change in the effective tax rate between periods was due to the Company being in a full valuation allowance for the three and nine months ended September 30, 2023.

Note 13 – Contingencies

In the normal course of business, the Company may be party to litigation from time to time. The Company maintains insurance to cover certain actions and believes that resolution of such litigation will not have a material adverse effect on the Company.

Overview

We are developing solid state battery technologies to enable the next generation of rechargeable batteries for the fast-growing EV and other markets.

Our core technology is our proprietary sulfide-based solid electrolyte material, which replaces the liquid or gel electrolyte used in conventional lithium-ion batteries. We believe that our electrolyte material can enable extended driving range, longer battery life, improved safety, and lower costs compared to conventional lithium-ion.

We also are designing and developing solid state cells that utilize our electrolyte in the cathode, anode, and separator layers. We currently produce 0.2 Ah, 2 Ah, 20 Ah, and EV cells on two pilot lines using established manufacturing processes.

We have partnered with industry leaders, including Ford Motor Company, BMW, and SK On Co., Ltd. We are working closely with each of these partners to refine and validate our cell designs and electrolyte material with the ultimate goal to commercialize our technologies. Our business model – selling our electrolyte to cell manufacturers and licensing our cell designs and manufacturing processes – distinguishes us from many of our competitors who plan to be commercial battery manufacturers. Ultimately, we endeavor to be a leading producer and distributor of sulfide-based solid electrolyte material for powering both EVs and other applications. Since we do not intend to commercially produce battery cells, we expect to invest less than other development-stage battery companies that plan to commercially manufacture their own cell designs and construct battery production facilities.

The products we currently make are in the development stage and require continued development and validation before we can commercialize either our electrolyte or cell technology.

Recent Business Highlights

● Made first A-1 EV cell deliveries to BMW in October to formally enter the automotive qualification process. These EV cell deliveries support BMW’s demo car program with additional deliveries projected over the coming months. 

● Increased SP2 electrolyte volume for EV cells and phased out production at our SP1 facility. This increase demonstrates the ability to manufacture at scale for potential partners. 

Key Factors Affecting Operating Results

We are a research and development-stage company and have not generated significant revenue through the sale of our electrolyte or licensing of our cell designs. Our ability to commercialize our products depends on several factors that present significant opportunities for us but also pose material risks and challenges, including those discussed in the “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” sections of this Report, which are incorporated by reference.

Prior to reaching commercialization, we must test and validate our products to ensure they meet the performance and safety requirements of our customers. We also will have to negotiate licensing and supply contracts with our customers on terms and conditions that are mutually acceptable. We will need to scale production of our electrolyte material to satisfy anticipated demand. All of these factors will take time and affect our operating results. Since many factors are difficult to quantify, our actual operating results may be different than we currently anticipate.

Our revenue generated to date has primarily come from research and development performance on government contracts and research and development licensing activities. We have deployed and are deploying substantial capital to expand our production capabilities and engage in research and development programs. We also continue to incur significantly more administrative expenses as a publicly traded company.

In addition to meeting our development goals and reaching commercialization, future growth and demand for our products will be highly dependent upon market adoption of EVs. The market for new energy vehicles is still rapidly evolving due to emerging technologies, competitive pricing, government regulation and industry standards, and changing consumer demands and behaviors.

Basis of Presentation

We currently conduct our business through one operating segment. As a research and development company with no commercial operations, our activities to date have been limited and were conducted primarily in the United States. Our historical results are reported under GAAP and in U.S. dollars.

Results of Operations

Comparison of the Three and Nine Months Ended September 30, 2023 to the Three and Nine Months Ended September 30, 2022

During the three and nine months ended September 30, 2023, we expanded and accelerated our development efforts through increased capital and operational investments. We continued to invest in talent while expanding our facilities, production equipment, and capabilities. We expect to continue to increase our spending in all operational areas through the remainder of 2023 in order to execute our development strategy.

The key factors driving our results of operations for the three and nine months ended September 30, 2023, including our increased operating loss as compared to the corresponding periods in 2022, were as follows:

● Revenue and direct costs – revenue and related direct costs from the execution of our JDAs drove the overall increase for the periods, while revenue and direct costs from performance on government contracts decreased slightly. We expect revenue and related direct costs to continue to increase in the remainder of 2023 as we execute on JDA deliverables.

● Research and development – our research and development costs increased for the periods primarily as a result of increased labor and material costs as we expanded the development efforts of our battery cells and electrolyte material. We expect our research and development costs to remain at increased levels as we continue the pace and scope of our development efforts.

● Selling, general and administrative – our selling, general and administrative expenses increased for the periods primarily due to additional use of outside professional services, additional planned hiring and workforce development associated with increasing our headcount to nearly 260 people, and enterprise resource planning system costs and implementation efforts.

● Operating expenses – non-cash stock-based compensation costs increased for the periods across direct costs, research and development costs, and selling, general and administrative expenses related to our increased headcount.

● Nonoperating income – our nonoperating income increased for the three-month periods primarily due to gain on fair value adjustment of warrant liabilities as well as yields on strategic cash investments in A-rated instruments, which increased our interest income. Our nonoperating income decreased for the nine-month periods primarily due to a lesser gain on fair value adjustment of warrant liabilities, partially offset by an increased gain in interest income related to strategic cash investment yields.

Liquidity and Capital Resources

Sources of Liquidity

Our primary sources of cash have historically been derived from the sale of equity, with a small portion coming from performance on government contracts and commercial revenues.

As of September 30, 2023 and December 31, 2022, we had total liquidity, as set forth below:

(in thousands)	September 30, 2023		December 31, 2022
Cash and cash equivalents	$	27,458	$	50,123
Marketable securities		166,030		272,957
Long-term investments		228,806		172,974
Total liquidity	$	422,294	$	496,054

Short-Term Liquidity Requirements

We anticipate that our most significant capital expenditures for the remainder of 2023 will relate to finishing construction of our electrolyte production and development facility. In addition, our short-term liquidity requirements include operating and capital expenses needed to further our technology development. We expect to fund our short-term liquidity requirements through our cash on hand and other liquid assets.

Long-Term Liquidity Requirements

We believe that our cash on hand is sufficient to meet our operating cash needs (including expenditures for the increased pace and scope of development as well as increased public company costs) and working capital and capital expenditure requirements for a period of at least the next 12 months and longer term until we generate adequate cash flows from licensing activities and/or electrolyte sales.

We may, however, need additional cash if there are material changes to our business conditions or other developments, including changes to our operating plan, development progress, delays in negotiations with OEMs, cell manufacturers, or other suppliers, market adoption of EVs, supply chain challenges, competitive pressures, inflation, and regulatory developments. To the extent that our resources are insufficient to satisfy our cash requirements, we may need to seek additional equity or debt financing. We also may opportunistically seek to enhance our liquidity through equity or debt financing, if such financing becomes available to us on terms that we consider favorable. If the financing is not available, or if the terms of financing are less desirable than we expect, we may be forced to take actions to reduce our capital or operating expenditures, which may adversely affect our development, business, operating results, financial condition, and prospects.

Cash Flows

The following table summarizes our cash flows from operating, investing, and financing activities for the periods presented:

	Nine Months Ended September 30,
(in thousands)	2023		2022
Net cash and cash equivalents used in operating activities	$	(51,651)	$	(30,486)
Net cash and cash equivalents provided by (used in) investing activities	$	28,955	$	(385,782)
Net cash and cash equivalents provided by financing activities	$	31	$	521

Cash used in operating activities:

Cash used in operating activities increased from September 30, 2022 to 2023. The increase was primarily attributable to our operating loss, which was driven by continued increase in research and development costs and selling, general and administrative expenses. We expect cash used in operating activities to remain at these increased levels as we continue the pace and scope of our development efforts and work to achieve commercialization of our products.

Cash provided by (used in) investing activities:

Cash provided by investing activities increased from September 30, 2022 to 2023 primarily due to the net effect of increased purchase and sales of marketable securities, in addition to decreased capital expenditures for property, plant and equipment. Capital expenditures were primarily for custom manufacturing equipment in connection with our expansion of electrolyte production capabilities. We expect cash used in investing activities to increase as we finalize the build out of our electrolyte production facility and increase its production capabilities, and as we increase our electrolyte production scale. As our production processes are scaled in the future for commercialization, especially with respect to our electrolyte material, we expect capital expenditures to increase.

Cash provided by financing activities:

Cash provided by financing activities for the nine months ended September 30, 2023 and 2022 were primarily related to the cash exercise of stock options and proceeds from the sale of shares of common stock under the ESPP, partially offset by leased equipment payments.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

In designing and evaluating our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired controls. As required by Rule 13a-15(b) under the Exchange Act, our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2023. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of the end of the period covered by this Report, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the three months ended September 30, 2023 covered by this Report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

Item 1A. Risk Factors

Our business, prospects, reputation, results of operations, and financial condition, as well as the price of our common stock and warrants, can be affected by a number of factors, whether currently known or unknown, including those described in “Part I, Item 1A. Risk Factors” of our 2022 Form 10-K and “Part II, Item 1A. Risk Factors” of our Q1 Form 10-Q, as such descriptions may be updated or amended in future filings we make with the SEC. When any one or more of these risks materialize from time to time, our business, reputation, results of operations, and financial condition, as well as the price of our common stock and warrants, can be materially and adversely affected. There have been no material changes to our risk factors since our Q1 Form 10-Q.
