Forward-Looking Statements Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or DCRN's, NewCo's or the Company's future financial or other performance metrics. For example (and without limitation), other than statements of present or historical fact, all statements concerning the following are forward-looking statements: summary financial forecast; projections of operating performance, revenues, gross margin, expenses, capital expenditures, total cost of goods sold, gross (loss) profit; estimates and projections regarding future manufacturing capacity; projections and estimates of market opportunity and market share; future profitability; the Company's business plan; market acceptance of the Company's offerings; the Company's ability to further attract, retain, and expand its customer base; the Company's ability to timely and effectively scale its production and manufacturing processes; the Company's ability to develop new products and services and bring them to market in a timely manner; the Company's expectations concerning relationships with strategic partners, suppliers, and other third parties; the Company's ability to maintain, protect, and enhance its intellectual property; future acquisitions, ventures or investments in companies or products, services, or technologies; the Company's ability to attract and retain qualified employees; continuation of favorable regulations and government incentives affecting the markets in which the Company operates; the proposed Business Combination; DCRN's ability to consummate the transaction in a timely manner or at all (including due to the failure to receive required shareholder approvals, or the failure of other closing conditions such as the satisfaction of the minimum trust account amount following redemptions by DCRN's public stockholders and the receipt of certain governmental and regulatory approvals); the combined company's future financial performance; proceeds of the Business Combination and the Company's expected cash runway; the combined company's strategy, future operations, estimated financial position, revenues and losses, and plans and objectives of management; and other potential effects of the Business Combination on DCRN and the Company. In some cases, you can identify forward-looking statements by terminology such as "believe," "may," "will," "potentially," "estimate," "continue," "anticipate," "intend," "could," "would," "project," "target," "plan," "expect," or the negatives of these terms or variations of them or similar terminology. Such 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. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by DCRN and its management, and the Company and its management, as the case may be, are inherently uncertain and subject to material change. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, various factors beyond management's control, including general economic conditions and other risks, uncertainties and factors set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in DCRN's final prospectus relating to its initial public offering, dated February 3, 2021, and other filings with the Securities and Exchange Commission (SEC), the risks described in the section "Risk Factors" in the Investor Presentation furnished as exhibit 99.3 to DCRN's Current Report on Form 8-K filed on May 26, 2021, other risks and uncertainties indicated from time to time in the proxy statement/prospectus relating to the proposed Business Combination, including those under "Risk Factors" therein, and in DCRN's other filings with the SEC, as well as factors associated with companies, such as the Company, that are engaged in electric vehicle charging technology, including anticipated trends, growth rates, and challenges in those businesses and in the markets in which they operate; macroeconomic conditions related to the global COVID-19 pandemic; trends with respect to rebates, tax credits and other financial incentives from governments, utilities and others to offset the purchase or operating cost of EVs and EV charging stations; expected rapid adoption of EVs for passenger and fleet applications; the size and growth of the market for alternative energy vehicles; the effects of increased competition; the ability to stay in compliance with laws and regulations that currently apply or become applicable to electric vehicle charging technology; the failure to realize the anticipated benefits of the Business Combination; the amount of redemption requests made by DCRN's public stockholders; the ability of NewCo to issue equity or equity-linked securities or obtain debt financing in connection with the Business Combination or in the future. 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 in this Presentation, which speak only as of the date they are made and are qualified in their entirety by reference to the cautionary statements herein. None of NewCo, DCRN nor the Company undertakes any duty to update these forward-looking statements. Use of Projections This Presentation contains projected financial information with respect to Tritium. Such projected financial information constitutes forward-looking information, and is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such financial forecast information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. See "Forward-Looking Statements" paragraph above. Actual results may differ materially from the results contemplated by the financial forecast information contained in this Presentation, and the inclusion of such information in this Presentation should not be regarded as a representation by any person that the results reflected in such forecasts will be achieved. None of DCRN's, NewCo's, nor the Company's independent auditors have audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, none of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Presentation. In preparing and making certain forward-looking statements contained in this presentation, Tritium, NewCo and DCRN made a number of economic, market and operational assumptions. Notably, statements regarding the Company's summary financial forecasts are, without limitation, subject to material assumptions regarding the Company's ability to economically manufacture and distribute its products at scale and meet its customers' business needs, the Company's ability to successfully execute its growth strategy, the Company's ability to maintain required strategic supply and distribution arrangements and customer relationships, rates of adoption of battery electric vehicles by customers in the markets in which the Company operates, and continuation of favorable regulations and government incentives affecting the markets in which the Company operates. DCRN, NewCo and the Company caution that these assumptions may not materialize and that current economic conditions render such assumptions, although believed reasonable at the time they were made, subject to greater uncertainty.

Disclaimer Additional Information In connection with the proposed Business Combination, DCRN and NewCo, which will be the going-forward public company, intend to file a registration statement on Form F-4 (the "Registration Statement") with the SEC, which will include a proxy statement/prospectus, and certain other related documents, to be used at the meeting of stockholders to approve the proposed Business Combination. INVESTORS AND SECURITY HOLDERS OF DCRN ARE URGED TO READ THE PROXY STATEMENT/PROSPECTUS, ANY AMENDMENTS THERETO AND OTHER RELEVANT DOCUMENTS THAT WILL BE FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY WHEN THEY BECOME AVAILABLE BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT TRITIUM, DCRN, NEWCO AND THE BUSINESS COMBINATION. After the registration statement is declared effective, DCRN will mail a definitive proxy statement/prospectus relating to the proposed Business Combination and other relevant materials to its shareholders as of the record date to be established for voting on the proposed Business Combination. This Presentation does not contain all the information that should be considered concerning the proposed Business Combination and is not intended to form the basis of any investment decision or any other decision in respect of the Business Combination. Shareholders will also be able to obtain copies of the preliminary proxy statement/prospectus, the definitive proxy statement/prospectus and other documents filed with the SEC, without charge, once available, at the SEC's website at www.sec.gov, or by directing a request to: Decarbonization Plus Acquisition Corporation II, 2744 Sand Hill Road, Menlo Park, CA 94025. Financial Information The financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X promulgated under the Securities Act of 1933, as amended (the "Securities Act"). Accordingly, 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 by NewCo with the SEC. Some of the financial information and data contained in this Presentation, such as EBITDA, gross profit and free cash flow, have not been prepared in accordance with United States generally accepted accounting principles ("GAAP"). DCRN, NewCo and Tritium believe these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Tritium's financial condition and results of operations. DCRN, NewCo and Tritium believe that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating projected operating results and trends in and in comparing Tritium's financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in Tritium's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures, in order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. This Presentation also includes certain projections of non-GAAP financial measures. Due to the high variability and difficulty 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 disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included. See "Use of Projections" paragraph above. Unless otherwise indicated, all historical or projected financial information and industry data contained in this Presentation is presented based on calendar years and not based on Tritium's fiscal year, which ends on 30 June. All monetary figures included in this Presentation are reflected in U.S. dollars unless otherwise indicated. Figures originally reported in Australian dollars were translated into U.S. dollars for the purposes of this presentation using the average AUD/USD foreign exchange rates for historical periods and 0.75 for all future periods shown. Participants in the Solicitation DCRN, NewCo, the Company and their respective directors and executive officers may be deemed participants in the solicitation of proxies from DCRN's shareholders with respect to the proposed Business Combination. A list of the names of DCRN's directors and executive officers and a description of their interests in DCRN is contained in DCRN's filings with the SEC, including the final prospectus relating to its initial public offering, dated February 3, 2021, which was filed with the SEC and is available free of charge at the SEC's web site at www.sec.gov, or by directing a request to Decarbonization Plus Acquisition Corporation II, 2744 Sand Hill Road, Menlo Park, CA 94025. Additional information regarding the interests of such participants in the solicitation of proxies from DCRN's shareholders with respect to the proposed Business Combination will be contained in the proxy statement/prospectus for the proposed Business Combination when available. No Offer or Solicitation This Presentation shall not constitute a "solicitation" of a proxy, consent, or authorization, as defined in Section 14 of the Securities Exchange Act of 1934, as amended, with respect to any securities or in respect of the proposed transaction. This Presentation also does not constitute an offer, or a solicitation of an offer, to buy, sell, or exchange any securities, investment or other specific product, or a solicitation of any vote or approval, nor shall there be any sale of securities, investment or other specific product in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities will be made except by means of a prospectus meeting the requirements of section 10 of the Securities Act of 1933, as amended, or an exemption therefrom. NEITHER THE SEC NOR ANY STATE SECURITIES COMMISSION HAS APPROVED OR DISAPPROVED OF THIS PRESENTATION OR DETERMINED IF THIS PRESENTATION IS TRUTHFUL OR COMPLETE. Trademarks and Trade Names Tritium and DCRN own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of their respective businesses.
