3 This presentation contains certain “forward - looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 , Section 27 A of the Securities Act and Section 21 E of the Securities Exchange Act of 1934 , as amended, including certain financial forecasts and projections . All statements other than statements of historical fact contained in this presentation, including statements as to future results of operations and financial position, revenue and other metrics planned products and services, business strategy and plans, objectives of management for future operations of Voltus, market size and growth opportunities, competitive position and technological and market trends, are forward - looking statements . Some of these forward - looking statements can be identified by the use of forward - looking words, including “may,” “should,” “expect,” “intend,” “will,” “estimate,” “anticipate,” “believe,” “predict,” “plan,” “targets,” “projects,” “could,” “would,” “continue,” “forecast” or the negatives of these terms or variations of them or similar expressions . All forward - looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward - looking statements . All forward - looking statements are based upon estimates, forecasts and assumptions that, while considered reasonable by Broadscale and its management, and Voltus and its management, as the case may be, are inherently uncertain and many factors may cause the actual results to differ materially from current expectations which include, but are not limited to : 1 ) the occurrence of any event, change or other circumstances that could give rise to the termination of the definitive merger agreement with respect to the business combination ; 2 ) the outcome of any legal proceedings that may be instituted against Voltus, Broadscale, the combined company or others following the announcement of the business combination and any definitive agreements with respect thereto ; 3 ) the inability to complete the business combination due to the failure to obtain approval of the stockholders of Broadscale or Voltus, or to satisfy other conditions to closing the business combination ; 4 ) changes to the proposed structure of the business combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the business combination ; 5 ) the ability to meet Nasdaq's listing standards following the consummation of the business combination ; 6 ) the risk that the business combination disrupts current plans and operations of Voltus as a result of the announcement and consummation of the business combination ; 7 ) the inability to recognize the anticipated benefits of the business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees ; 8 ) costs related to the business combination ; 9 ) changes in applicable laws or regulations ; 10 ) the possibility that Voltus or the combined company may be adversely affected by other economic, business and/or competitive factors ; 11 ) Voltus’ estimates of its financial performance ; 12 ) the risk that the business combination may not be completed in a timely manner or at all, which may adversely affect the price of Broadscale’s securities ; 13 ) the risk that the transaction may not be completed by Broadscale’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by Broadscale ; 14 ) the impact of the novel coronavirus disease pandemic, including any mutations or variants thereof, and its effect on business and financial conditions ; 15 ) inability to complete the PIPE investment in connection with the business combination ; and 16 ) other risks and uncertainties set forth in the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward - Looking Statements” in Broadscale’s Form S - 1 (File Nos . 333 - 252449 and 333 - 253016 ), Quarterly Report on Form 10 - Q for the quarterly period ended September 30 , 2021 and registration statement on Form S - 4 with the SEC, which will include a document that serves as a prospectus and proxy statement of Broadscale, referred to as a proxy statement/prospectus and other documents filed by Broadscale from time to time with the SEC . These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward - looking statements . Forward - Looking Statements This document contains financial, operational, industry and market projections . No independent auditor has audited, studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this document, and accordingly, no independent auditor has expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this document . These projections are forward - looking statements and should not be relied upon as being necessarily indicative of future results . In this document, certain of the above - mentioned projected information has been provided for purposes of providing comparisons with historical data . The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties, many of which are beyond the Company’s and Broadscale’s control, that could cause actual results to differ materially from those contained in the prospective financial information, including assumptions, risks and uncertainties described in “Forward - Looking Statements” above . Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or Broadscale or that actual results will not differ materially from those presented in the prospective financial information . While all financial, operational, industry and market projections, estimates and targets are necessarily speculative, Broadscale and Voltus believe that the preparation of prospective financial, operational, industry and market information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation . Inclusion of the prospective financial information in this document should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved . Use of Projections Legal Disclaimer Nothing in this presentation should be regarded as a representation by any person that the forward - looking statements set forth herein will be achieved or that any of the contemplated results of such forward looking statements will be achieved . You should not place undue reliance on forward - looking statements, which speak only as of the date they are made . Neither Broadscale nor Voltus gives any assurance that either Broadscale or Voltus or the combined company will achieve its expected results . Neither Broadscale nor Voltus undertakes any duty to update these forward - looking statements, except as otherwise required by law .

4 The financial information and data contained in this document is unaudited and does not conform to Regulation S - X . Such information and data may not be included in, may be adjusted in or may be presented differently in the registration statement to be filed relating to the Transaction and the proxy statement/prospectus contained therein . This document also includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, EBITDA, Free Cash Flow and certain ratios and other metrics derived therefrom . These non - GAAP financial measures, and other measures that are calculated using these non - GAAP measures, are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing the Company’s financial results . Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP . You should be aware that the Company’s presentation of these measures may not be comparable to similarly - titled measures used by other companies . The Company believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations . Broadscale and the Company believes that the use of these non - GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non - GAAP financial measures to investors . These non - GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non - GAAP financial measures . This document may also include certain projections of non - GAAP financial measures . Due to the high variability and di ffi culty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort . Consequently, no reconciliation of the forward - looking non - GAAP financial measures is included . Financial Information; Non - GAAP Measures This presentation contains certain information concerning the Company’s products, services and industry that are based on industry surveys and publications or other publicly available information, other information obtained from third - party sources, and the Company’s internal sources . This information involves many assumptions and limitations ; therefore, there can be no guarantee as to the accuracy or reliability of such assumptions and you are cautioned not to give undue weight to this information . Further, no representation is made as to the reasonableness of the assumptions made within or the accuracy or completeness of any projections or modeling or any other information contained herein . Any data on past performance or modeling contained herein are not an indication as to future performance . None of Voltus, Broadscale or their respective affiliates, officers, directors, employees, representatives or advisors has independently verified the accuracy or completeness of any such third - party information . Similarly, other third - party survey data and research reports commissioned by the Company or Broadscale, while believed by to be reliable, are based on limited sample sizes and have not been independently verified by the Company or Broadscale . In addition, projections, assumptions, estimates, goals, targets, plans and trends of the future performance of the industry in which Voltus operates, and its future performance, are necessarily subject to uncertainty and risk due to a variety of factors, including those described above . These and other factors could cause results to differ materially from those expressed in the estimates made by independent parties and by Voltus and Broadscale . Industry and Market Data Broadscale will be required to file a preliminary and definitive proxy statement, which may be a part of a registration statement, and other relevant documents with the SEC . Stockholders and other interested persons are urged to read the proxy statement and any other relevant documents filed with the SEC when they become available because they will contain important information about Broadscale, Voltus and the contemplated business combination . Shareholders will be able to obtain a free copy of the proxy statement (when filed), as well as other filings containing information about Broadscale, Voltus and the contemplated business combination, without charge, at the SEC's website located at www . sec . gov . Broadscale, Voltus and their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from Broadscale's shareholders in connection with the proposed transaction . A list of the names of such directors and executive officers and information regarding their interests in the business combination will be contained in the proxy statement/prospectus when available . You may obtain free copies of these documents free of charge by directing a written request to Voltus . This presentation does not contain all the information that should be considered in the contemplated business combination . It is not intended to form any basis of any investment decision or any decision in respect to the contemplated business combination . The definitive proxy statement will be mailed to shareholder as of a record date to be established for voting on the contemplated business combination when it becomes available .

Trademarks

5 Key Risks General Business and Industry - Related Risks • Voltus operates in highly complex and competitive markets; if Voltus is unable to compete successfully, it could lose market share and revenues . • If Voltus loses key personnel upon whom it is dependent, or if Voltus fails to attract and retain qualified personnel, it may not be able to manage its operations and meet its strategic objectives . • If Voltus fails to manage its growth effectively, including failing to attract and integrate qualified personnel, it may not be able to develop, produce, market and sell its hardware and software - enabled services successfully . • An increased rate of terminations by Voltus’s existing customers and providers, which we collectively refer to as our customers, Voltus’s failure to renew contracts when they expire or its failure to attract new customers would negatively impact Voltus’s business by reducing its revenues and requiring it to spend more money to maintain and grow its customer base . • Although Voltus’s sales cycles tend to be relatively short, if those were to lengthen in time and/or become unpredictable, then managing its sales cycles will require significant employee time and financial resources with no assurances that it will realize revenues . • If Voltus fails to obtain favorable prices in the wholesale electricity markets, demand response programs and other programs in which it currently participates or chooses to participate in the future, its revenues, gross profits and profit margins will be negatively impacted . • If the actual amount of demand response capacity that Voltus makes available under its capacity commitments is less than required, Voltus’s committed capacity could be reduced and it could be required to make refunds or pay penalty fees, which could negatively impact Voltus’s results of operations and financial condition . • The success of Voltus’s businesses depends in part on its ability to develop new products and services, increase the functionality of its current products and expand its products and services into new markets . • A significant portion of Voltus’s revenues are generated from arrangements with a small number of utility and grid operator customers, the postponement, modification or termination of which could significantly reduce Voltus’s revenues . • Pressure on the prices in the demand response programs and other programs in which the Company currently participates or chooses to participate in the future, or on the percentage or fixed amount paid to commercial and industrial end - users for making capacity available, could adversely affect Voltus’s results of operations and financial condition . • If distributed energy resource technologies are not suitable for widespread adoption or sufficient demand for Voltus’s hardware and software - enabled services does not develop or takes longer to develop than anticipated, Voltus’s sales may decline and it may be unable to achieve or sustain profitability . • Voltus depends on the electric power industry for revenues and as a result, its operating results have experienced, and may continue to experience, significant variability due to volatility in electric power industry spending, capacity and energy prices, and other factors affecting the electric utility industry, such as seasonality of peak demand and overall demand for electricity . • Voltus may require significant additional capital to pursue its growth strategy, but it may not be able to obtain additional financing on acceptable terms or at all . • Voltus’s ability to provide bid bonds, performance bonds or letters of credit is limited and could negatively affect its ability to bid on or enter into significant long - term commitments with grid operators and utilities . • Voltus operations may be adversely affected by the coronavirus outbreak, and it faces disruption risks from the coronavirus that could impact its business, including supply chain risks that could result in insufficient inventory and negatively impact Voltus’s business . • The extent to which the COVID - 19 pandemic and resulting deterioration of worldwide economic conditions adversely impact our business, financial condition, and operating results will depend on future developments, which are difficult to predict . • Voltus may not be able to maintain quality customer care during periods of growth or in connection with the addition of new and complex products or services, which could adversely affect its ability to acquire and retain customers and participants in its programs . • If Voltus is unable to expand the distribution of its products and services through strategic alliances with its partners and third parties, it may not be able to grow its business . • Current or future market developments may adversely affect Voltus’s business, results of operations and access to capital . • Voltus’s operations rely on the infrastructure of utilities and grid operators, which provide electricity to and obtain information about Voltus’s customers . Any infrastructure failure could negatively impact customer satisfaction and could have a material adverse effect on Voltus’s business and operations . • Events that negatively impact the growth of distributed energy resources will have a negative impact on Voltus’s business and financial condition . • The distributed energy resource industry is an emerging market and Voltus’s offerings may not receive widespread market acceptance . • Voltus’s platform performance may not meet its customers’ expectations or needs . • Voltus must maintain customer confidence in its long - term business prospects in order to grow its business . • If Voltus is unsuccessful in developing and maintaining its proprietary technology, including the VOLTAPP platform, Voltus’s ability to attract and retain partners could be impaired, its competitive position could be adversely affected and its revenue could be reduced . • Negative attitudes, rule changes and policies toward distributed energy resource offerings and technologies from the U . S . government, other lawmakers and regulators, and activists could adversely affect Voltus’s business, financial condition and results of operations . • While Voltus has not made material acquisitions to date, it intends to pursue acquisitions in the future and will be subject to risks associated with acquisitions . • Voltus faces risks related to its expansion into international markets . • Fluctuations in the exchange rates of foreign currencies in which Voltus conducts its business, in relation to the U . S . dollar, could harm its business and prospects . These risk factors are being provided to certain sophisticated institutional investors for potential investment in Broadscale Ac quisition Corp. (“Broadscale”) as part of a proposed business combination between Voltus, Inc. or an affiliate thereof (“Volt us” ) and Broadscale, pursuant to which Voltus will become a publicly traded operating company (the “Business Combination”). Investing in securitie s ( the “Securities”) to be issued in a private placement in connection with the Business Combination involves a high degree of r isk . Investors should carefully consider the risks and uncertainties inherent in an investment in Broadscale and in the Securities, includin g t hose described below, together with any other information provided to investors, and should carry out their own diligence and co nsult with their own financial and legal advisors concerning the risks and suitability of an investment in this offering before subscribing for th e S ecurities. If Broadscale, Voltus or, following the consummation of the Business Combination, the combined company, cannot add res s any of the following risks and uncertainties effectively, or any other risks and difficulties that may arise in the future, the combined co mpany’s business, financial condition or results of operations could be materially and adversely affected. Additional risks a nd uncertainties not presently known to Broadscale or Voltus or that Broadscale or Voltus currently deem immaterial may also impair the combined c omp any’s business operations. Risks relating to Voltus’ business will be disclosed in future documents filed or furnished by Vol tus and/or Broadscale with the United States Securities and Exchange Commission (“SEC”), including the documents filed or furnished in c onn ection with the proposed transactions between Voltus and Broadscale. The risks presented in such filings will be consistent w ith those that would be required for a public company in their SEC filings, including with respect to the business and securities of Broadsc ale and Voltus and the proposed transactions between Broadscale and Voltus, and may differ significantly from, and be more extens iv e than, those presented below.

6 Key Risks (cont’d) Risks Related to Information Technology and Intellectual Property • The operation of Voltus’s businesses relies on information technology systems and third - party service providers . Failure of information technology systems or by third - party service providers could have a material adverse impact on Voltus’s business, operations, financial condition and cash flows . • Any internal or external security breaches, information technology system failures, cyber security attacks or network distributions that involve Voltus’s products or its business could harm its reputation, business operations, energy usage and financial conditions and even the perception of security risks, whether or not valid, could inhibit market acceptance of Voltus’s products and cause Voltus to lose customers . • If Voltus’s information technology systems fail to adequately gather, assess and protect data used in providing its distributed energy resource solutions, or if Voltus experiences an interruption in its operation, its business, financial condition and results of operations could be adversely affected . • The use of open source software in Voltus’s systems and technology may expose it to additional risks and harm its intellectual property . • If Voltus is unable to protect its intellectual property, its business and results of operations could be negatively affected . • Voltus may be subject to damaging and disruptive intellectual property litigation related to allegations that its products or services infringe on intellectual property held by others, which could result in the loss of use of the product or service . • Voltus primarily relies on Amazon Web Services (“AWS”) to deliver its services to users on its platform, and any disruption of or interference with Voltus’s use of AWS could adversely affect its business, financial condition and results of operations . Risks Related to Voltus’s Equity • The market price of Voltus’s common stock could be volatile, and you could lose all or part of your investment . • Voltus expects its quarterly revenues and operating results to fluctuate . If Voltus fails in future periods to meet its publicly announced financial guidance or the expectations of securities analysts or investors, the market price of Voltus’s common stock could decline substantially . • Voltus does not intend to pay dividends on its common stock . • If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about Voltus’s business, its stock price and trading volume could decline . • The requirements of being a public company, including compliance with the reporting requirements of the Securities Exchange Act of 1934 , as amended and The NASDAQ Stock Market LLC, will require significant resources, increase New Voltus’s costs and distract its management, and New Voltus may be unable to comply with these requirements in a timely or cost - effective manner . • Any future sales or offerings of Voltus’s common stock may cause substantial dilution to its stockholders and could cause the price of its common stock to decline . • Recently, there have been changes to the accepted accounting for special purpose acquisition companies ("SPACs") . For example, on April 12 , 2021 , the Staff of the SEC issued a statement related to warrants issued by SPACs (the “SEC Statement”), which resulted in the warrants issued by many SPACs being required to be classified as liabilities rather equity . Broadscale has accounted for its outstanding warrants as a warrant liability and will be required to determine the value warrant liability quarterly, which could have a material impact on its financial position and operating results . Changes in the accepted accounting related to SPACs may also result in the recognition of accounting errors in previously issued financial statements, restatements of previously issued audited financial statements, the filing of notices that previously issued financial statements may not be relied upon, and findings of material weaknesses and significant deficiencies in internal controls over financial reporting . In addition, such changes could delay or have a material adverse effect on Broadscale and Voltus’ ability to consummate the Business Combination . Risks Related to Accounting and Finance Matters and Projections • Voltus has identified a material weakness in its internal controls over financial reporting . If Voltus is unable to remediate the material weakness, or if Voltus identifies additional material weaknesses in the future or otherwise fails to maintain an effective system of internal control over financial reporting, this may result in material misstatements or restatements of Voltus’s consolidated financial statements or cause Voltus to fail to meet its periodic reporting obligations . • Once the Business Combination is consummated, the combined company (“New Voltus”) will be exposed to potential risks and will incur significant costs as a result of the internal control testing and evaluation process mandated by Section 404 of the Sarbanes - Oxley Act of 2002 . New Voltus’s failure to timely and effectively implement controls and procedures required by Section 404 (a) of the Sarbanes - Oxley Act that will be applicable to it after the merger is consummated could have a material adverse effect on its business . • Voltus has incurred significant losses in the past and does not expect to be profitable before 2025 . • The estimates and assumptions on which our financial projections are based may prove to be inaccurate, which may cause our actual results to materially differ from such projections, and which may adversely affect our future profitability, cash flows and the market price of our common stock . • If the estimates and assumptions Voltus uses to determine the size of its total addressable market are inaccurate, its future growth rate may be affected and the potential growth of its business may be limited . • Voltus’s limited operating history at current scale and its nascent industry make evaluating its business and future prospects difficult . • Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the merger or other ownership changes . • New Voltus will qualify as an “emerging growth company” within the meaning of the Securities Act, and if it takes advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make New Voltus’s securities less attractive to investors and may make it more difficult to compare New Voltus’s performance to the performance of other public companies . • The Broadscale Warrants are accounted for as liabilities and the changes in value of such warrants could have a material effect on New Voltus’s financial results following the merger . Risks Related to the Business Combination • Each of Voltus and Broadscale will incur significant transaction costs in connection with the Business Combination . • The consummation of the Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Business Combination agreement may be terminated in accordance with its terms and the Business Combination may not be completed • The ability to successfully effect the Business Combination and New Voltus’s ability to successfully operate the business thereafter will be largely dependent upon the efforts of certain key personnel of New Voltus . The loss of such key personnel could negatively impact the operations and financial results of the combined business . Risks Related to the Regulatory Environment and Litigation • Unfavorable regulatory decisions and/or policies, including rule changes made by regulatory agencies such as FERC, changes to the market rules applicable to the demand response programs in which Voltus currently participates or may participate in the future, and varying regulatory structures in certain regional electric power markets could negatively affect Voltus’s business and results of operations . • Voltus’s business is subject to government regulation and may become subject to modified or new government regulation, which may increase its costs and negatively impact its ability to sell and market its various product and service offerings . • Regulatory investigations or other administrative proceedings could expose Voltus to significant liabilities and reputational damage that could have a material adverse effect on Voltus . • Failure to comply with laws and regulations could harm Voltus’s business . • Current or future litigation or administrative proceedings could have a material adverse effect on Voltus’s business, reputation, financial condition and results of operations .
