This prospectus relates to the offer and sale by the selling securityholders or their permitted transferees (collectively, the “Selling Securityholders”) of up to 52,886,962 ordinary shares, no par value (“Ordinary Shares”), of Tritium DCFC Limited, a public limited company organized under the laws of Australia (the “Company”), consisting of up to (i) 43,367,526 Ordinary Shares issued to certain affiliated securityholders of the Company (excluding DCRN Sponsor (as defined below)) in connection with the acquisition by the Company of all of the issued equity interests in Tritium Holdings Pty Ltd and merger of Decarbonization Plus Acquisition Corporation II, a Delaware corporation (“DCRN”) with and into Hulk Merger Sub, Inc. (“Merger Sub”), in each case, on the terms and subject to the conditions set forth in the Business Combination Agreement, dated May 25, 2021 by and among Decarbonization Plus Acquisition Corporation II, Tritium Holdings Pty Ltd, Tritium DCFC Limited and Hulk Merger Sub, Inc. (such agreement referred to as the “Business Combination Agreement” and such transaction referred to as the “Business Combination”), including shares issued to DCRN Sponsor pursuant to the separate option agreements (each, an “Option Agreement” and together, the “Option Agreements”), each dated January 13, 2022, with each of (a) St Baker Energy Holdings Pty Ltd, (b) Varley Holdings Pty Ltd, (c) Ilwella Pty Ltd and (d) Decarbonization Plus Acquisition Sponsor II LLC (each an “Option Holder”), or as stock-based compensation to certain of our executive officers, (ii) 1,000,000 Ordinary Shares the Company issued to Palantir Technologies Inc. (“Palantir”) in connection with the A&R Subscription Agreement (as defined below); (iii) 6,770,379 Ordinary Shares held by Decarbonization Plus Acquisition Sponsor II LLC, a Delaware limited liability company (“DCRN Sponsor”) that were (x) issued to DCRN Sponsor in connection with the Option Agreements or (y) previously held as Class B common stock of DCRN, which was converted into Class A common stock of DCRN in accordance with DCRN’s amended and restated certificate of incorporation at the effective time of the merger in connection with the Business Combination and subsequently exchanged for Ordinary Shares; and (iv) 1,749,057 Ordinary Shares issued by the Company in private placements to DCRN Sponsor upon the “cashless” exercise of warrants that were originally issued to such holders in connection with private placements by DCRN to such holders, including 691,725 warrants that were issued to DCRN Sponsor as warrants for Ordinary Shares of the Company at the closing of the Business Combination in connection with working capital loans made by DCRN Sponsor to DCRN (the “Private Placement Warrants”). The number of Ordinary Shares registered for resale by each holder is based on holdings information known to the Company as of March 1, 2023.

We are registering the offer and sale of the securities held by the Selling Securityholders, in some cases, to satisfy certain registration rights we have granted, and in other cases, to provide for resale by affiliates of the Company under the Securities Act of 1933, as amended, or the “Securities Act.” Subject to existing lockup or other restrictions on transfer, the Selling Securityholders may offer all or part of the securities for resale from time to time through public or private transactions, at either prevailing market prices or at privately negotiated prices. These securities are being registered to permit the Selling Securityholders to sell securities from time to time, in amounts, at prices and on terms determined at the time of offering. The Selling Securityholders may sell these securities through ordinary brokerage transactions, directly to market makers of our shares or through any other means described in the section entitled “Plan of Distribution” herein. In connection with any sales of

ordinary shares offered hereunder, the Selling Securityholders, any underwriters, agents, brokers or dealers participating in such sales may be deemed to be “underwriters” within the meaning of the Securities Act.

We are registering these securities for resale by the Selling Securityholders named in this prospectus, or their transferees, pledgees, donees or assignees or other successors-in-interest (that receive any of the shares as a gift, distribution, or other non-sale related transfer).

This prospectus also relates to the issuance by us of up to an aggregate of 9,268,131 Ordinary Shares, which consists of (i) up to 241,147 Ordinary Shares that are issuable upon the exercise of 241,147 Private Placement Warrants and (ii) up to 9,026,984 Ordinary Shares that are issuable upon the exercise of 9,026,984 Warrants, originally issued as warrants of DCRN sold to the public in DCRN’s initial public offering (“Public Warrants” and, together with the Private Placement Warrants (but excluding the Financing Warrants (as defined below)), the “Warrants”), based on the number of issued Public Warrants on March 1, 2023. We will receive the proceeds from any exercise of any warrants for cash.

We will not receive any proceeds from the sale of the securities by the Selling Securityholders.

This prospectus also covers any additional securities that may become issuable by reason of share splits, share dividends or other similar transactions.

Our Ordinary Shares and Warrants are listed on The Nasdaq Stock Market LLC (“Nasdaq”) under the trading symbols “DCFC” and “DCFCW,” respectively. On March 9, 2023, the last reported sale price of our Ordinary Shares was $1.66 per share and the last reported sale price of our Warrants was $0.58 per Warrant. If the price of our Ordinary Shares is below $6.90 per share, the exercise price of our Warrants, warrant holders will be unlikely to cash exercise their Warrants resulting in little or no cash proceeds to us.

The Selling Securityholders named herein are comprised of DCRN Sponsor, directors and certain legacy investors in Tritium Holdings (as defined herein), Palantir and certain of our executive officers. The following table provides the number of Ordinary Shares offered hereby by each Selling Securityholder as well as the historical weighted-average price paid per Ordinary Share by each Selling Securityholder:

For information about the price paid by the Selling Securityholders, including prices paid by legacy Tritium Holdings investors and certain of our executive officers, to acquire our Ordinary Shares, see “Risk Factors—Certain existing shareholders purchased securities in the Company at a price below the current trading price of such securities, and may realize significant profits in the event of an increase in trading price. Future investors in our Company may not experience a similar investment return.”

Our Ordinary Shares and Warrants are listed on The Nasdaq Stock Market LLC (“Nasdaq”) under the trading symbols “DCFC” and “DCFCW,” respectively. On March 22, 2023, the last reported sale price of our Ordinary Shares was $1.07 per share and the last reported sale price of our Warrants was $0.35 per Warrant. If the price of our Ordinary Shares is below $6.90 per share, the exercise price of our Warrants, warrant holders will be unlikely to cash exercise their Warrants resulting in little or no cash proceeds to us.

THE COMPANY

Overview

We design, sell, manufacture and service proprietary hardware and associated software to create advanced and reliable direct current (“DC”) fast chargers for electric vehicles (“EVs”). Our technology is engineered to be easy to install, own and use. Our compact, robust chargers are designed to look great on Main Street and thrive in harsh conditions. As of December 31, 2022, we have already sold over 10,000 DC fast chargers and have provided high-power charging sessions across 42 countries.

We are a technology provider that primarily generates revenue from the sale of DC fast-charging solutions. Our solutions are made up of core charging hardware, including embedded on-device firmware, and adjacent software platforms that let owners monitor and manage their assets. Our charging station hardware portfolio includes stand-alone chargers and distributed chargers, and our software products include Tritium Pulse Software and MyTritium Software. We offer ongoing maintenance services including the provision of spare parts, extended warranties, services outside warranty and a range of service level agreement options. We are currently focused on key customer types across the charging landscape, such as Charge Point Operators, Automakers, Fleets, Fuel Stations, Retail and Utilities, but our products are segment-agnostic and can be used across all target sectors. In the future, we also aim to address the emerging markets of heavy-duty vehicle charging and residential and fleet low-power DC charging.

Our principal executive offices are located at Tritium DCFC Limited, 48 Miller Street, Murarrie, QLD 4172, Australia. Our telephone number is +61 (07) 3147 8500. Our website address is www.tritiumcharging.com. The information on, or that may be accessed through, our website is not a part of this prospectus supplement or the accompanying prospectus.

We own or have rights to various trademarks, service marks and trade names that we use in connection with the operation of our businesses. This prospectus also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners. The use or display of third parties’ trademarks, service marks, trade names or products in this prospectus is not intended to create, and does not imply, a relationship with us, or an endorsement or sponsorship by or of us. Solely for convenience, the trademarks, service marks and trade names referred to in this prospectus may appear with the ^®, TM or SM symbols, but such references are not intended to indicate, in any way, that we will not assert, to the fullest extent under applicable law, our rights or the right of the applicable licensor to these trademarks, service marks and trade names.

Implications of Being an “Emerging Growth Company” and a Foreign Private Issuer

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, we are eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies,” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic reports, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved (to the extent applicable to a foreign private issuer). If some investors find our securities less attractive as a result, there may be a less active trading market for our securities and the prices of our securities may be more volatile.

We will remain an emerging growth company under the JOBS Act until the earliest of (a) the last day of our first fiscal year following the fifth anniversary of the date of effectiveness of our registration statement on Form F-4, filed in connection with the Business Combination (as defined below), (b) the last date of our fiscal year in which we have total annual gross revenue of at least $1.235 billion, (c) the date on which we are deemed to be a

5

“large accelerated filer” under the rules of the SEC with at least $700.0 million of issued securities held by non-affiliates or (d) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three years. References herein to “emerging growth company” shall have the meaning associated with it in the JOBS Act.

We report under the Exchange Act as a non-U.S. company with foreign private issuer status. Even after we no longer qualify as an emerging growth company, as long as we qualify as a foreign private issuer under the Exchange Act we will be exempt from certain provisions of the Exchange Act that are applicable to U.S. domestic public companies, including, but not limited to:

We intend to take advantage of these exemptions until such time as we are no longer a foreign private issuer. We would cease to be a foreign private issuer at such time as (i) more than 50% of our issued voting securities are held by U.S. residents and (ii) any of the following three circumstances applies: (A) the majority of our executive officers or directors are U.S. citizens or residents, (B) more than 50% of our assets are located in the United States or (C) our business is administered principally in the United States. See “Description of Securities” for more information.

Both foreign private issuers and emerging growth companies are also exempt from certain more stringent executive compensation disclosure rules. Thus, even if we no longer qualify as an emerging growth company but remain a foreign private issuer, we will continue to be exempt from the more stringent compensation disclosures required of companies that are not emerging growth companies and will continue to be permitted to follow our home country practice on such matters.

RISK FACTORS

Investment in any securities offered pursuant to this prospectus and the applicable prospectus supplement involves risks. Before deciding whether to invest in our securities, you should carefully consider the risk factors described below and in our most recent Annual Report on Form 20-F incorporated by reference into this prospectus, our updates, if any, to those risk factors in our reports on Form 6-K incorporated by reference into this prospectus, all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement and any applicable free writing prospectus. The occurrence of any of these risks might cause you to lose all or part of your investment in the offered securities. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be seriously harmed. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section entitled “Cautionary Note Regarding Forward-Looking Statements” included herein and included in our most recent Annual Report on Form 20-F and our updates, if any, to that section in our reports on Form 6-K incorporated by reference into this prospectus.

Risks Related to our Securities

Sales of a substantial number of our securities in the public market by the Selling Securityholders and/or by our existing securityholders could cause the price of our Ordinary Shares and Warrants to fall.

The Selling Securityholders can resell, under this prospectus, up to 52,886,962 Ordinary Shares (excluding Ordinary Shares issuable upon exercise of the Warrants) constituting approximately 33.8% of our issued Ordinary Shares. Sales of a substantial number of Ordinary Shares in the public market by the Selling Securityholders and/or by our other existing securityholders, or the perception that those sales might occur, could depress the market price of our Ordinary Shares and Warrants and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effect that such sales may have on the prevailing market price of our Ordinary Shares and Warrants.

Certain existing shareholders purchased securities in the Company at a price below the current trading price of such securities, and may realize significant profits in the event of an increase in trading price. Future investors in our Company may not experience a similar investment return.

Certain shareholders in the Company, including certain of the Selling Securityholders, acquired Ordinary Shares at prices below the current trading price of our Ordinary Shares, and may realize significant profits in the event of an increase in trading price.

Of the 8,519,436 Ordinary Shares included hereby for offer and resale by DCRN Sponsor (“DCRN Sponsor Shares”), 1,749,057 Ordinary Shares were acquired upon “cashless” exercise of 5,580,325 Warrants, 4,888,600 of which were originally acquired by DCRN Sponsor as warrants for common stock of DCRN in connection with a private placement concurrent with DCRN’s initial public offering, and 691,725 of which were issued as warrants for Ordinary Shares of the Company at the closing of the business combination in connection with working capital loans made by DCRN Sponsor to DCRN, in each case, at a price of $1.50 per whole warrant and for aggregate consideration of approximately $12.1 million. The 4,888,600 private placement warrants were later assumed by us in connection with the Business Combination. After assumption, each whole Warrant became exercisable for one Ordinary Share at a price of $6.90 and were also exercisable on a “cashless” basis in accordance with the terms of our Amended and Restated Warrant Agreement. Also included in the DCRN Sponsor Shares are (i) 6,489,021 Ordinary Shares originally acquired as founder shares in DCRN in connection with DCRN’s initial public offering for which DCRN Sponsor paid an aggregate of approximately $25 thousand and (ii) 281,358 Ordinary Shares acquired by DCRN Sponsor in connection with the Option Agreements.

9

Additionally, this prospectus includes for offer and resale by Palantir and certain of our affiliates, including certain legacy shareholders of Tritium Holdings and certain of our directors and executive officers, up to 44,367,526 Ordinary Shares.

The following table provides the number of Ordinary Shares offered hereby by each Selling Securityholder as well as the (i) historical total amount paid, (ii) the historical weighted-average price paid per Ordinary Share and (iii) the potential profit earned by each Selling Securityholder:

Based on the last reported sale price of our Ordinary Shares on March 9, 2023 of $1.66 per share, certain of the Selling Securityholders named in this prospectus would realize significant profits on the sale of their holdings as compared to the initial consideration paid for such holdings, as detailed above.

Each whole Warrant is exercisable for one Ordinary Share at a price of $6.90, and may also be exercised on a cashless basis in accordance with the terms of our Amended and Restated Warrant Agreement.

Given the relatively lower purchase prices that some of our shareholders paid to acquire Ordinary Shares compared to the current trading price of our Ordinary Shares, these shareholders, some of whom are our Selling Securityholders, in some instances will realize significant profits, depending on the market price of our Ordinary Shares at the time that such shareholders choose to sell their Ordinary Shares. Investors who purchase our Ordinary Shares in the open market following the Business Combination may not experience a similar rate of return on the securities they purchase due to differences in the purchase prices and the current trading price. Additionally, even though our Ordinary Shares may be trading at a price below the trading price of DCRN’s common stock prior to the Business Combination, certain affiliates may still be incentivized to sell their shares due to the relatively lower price they paid to acquire such shares.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements contained in this prospectus constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. Forward-looking statements reflect our current views, as applicable, with respect to, among other things, our respective capital resources, portfolio performance and results of operations. Likewise, all statements regarding anticipated growth in our operations, anticipated market conditions, demographics and results of operations are forward-looking statements. In some cases, you can identify these forward-looking statements by the use of terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates” or the negative version of these words or other comparable words or phrases.

The forward-looking statements contained in this prospectus reflect our current views, as applicable, about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances that may cause its actual results to differ significantly from those expressed in any forward-looking statement. We do not guarantee that the transactions and events described will happen as described (or that they will happen at all). The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

11

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, new information, data or methods, future events or other changes after the date of this prospectus, except as required by applicable law. For a further discussion of these and other factors that could cause our future results, performance or transactions to differ significantly from those expressed in any forward-looking statement, please see the section entitled “Risk Factors” in our 2022 Form 20-F incorporated by reference into this prospectus. You should not place undue reliance on any forward-looking statements, which are based only on information currently available to us (or to third parties making the forward-looking statements). You should also carefully consider the cautionary statements contained or referred to in this section in connection with the forward-looking statements contained in this prospectus and any subsequent written or oral forward-looking statements that may be issued by us or persons acting on our behalf.

12

USE OF PROCEEDS

We will receive up to $64.0 million from the exercise of the Warrants, assuming the exercise in full of all of the Warrants for cash, based on 9,268,131 issued Warrants as of March 1, 2023. If the Warrants are exercised pursuant to a cashless exercise feature, we will not receive any cash from these exercises. Subsequent to the Business Combination, we received approximately $26.6 million in proceeds from the cash exercise by public warrant holders of 3,851,045 Warrants. As of March 9, 2023, the last reported sale price of our Ordinary Shares was $1.66 per share. If the price of our Ordinary Shares remains below $6.90 per share, the exercise price of our Warrants, warrant holders will be unlikely to cash exercise their Warrants resulting in little or no cash proceeds to us. Additionally, subsequent to the Business Combination, 538,563 Warrants were exercised on a “cashless” basis by public warrant holders and 8,125,520 Warrants were exercised on a “cashless” basis by DCRN Sponsor and certain of DCRN’s previous independent directors. We expect to use the net proceeds from the exercise of the Warrants, if any, for general corporate purposes. Our management will have broad discretion over the use of proceeds from the exercise of the Warrants.

The Selling Securityholders will receive all of the net proceeds from the sale of any Ordinary Shares offered by them under this prospectus.

We will bear all costs, expenses and fees in connection with the registration of the Ordinary Shares offered by the Selling Securityholders pursuant to this prospectus, whereas the Selling Securityholders will bear all incremental selling expenses, including commissions, brokerage fees and other similar selling expenses.

The table below sets forth, as of the date of this prospectus, the name of the Selling Securityholders for which we are registering Ordinary Shares for resale to the public, and the aggregate principal amount that the Selling Securityholders may offer pursuant to this prospectus. In accordance with SEC rules, individuals and entities below are shown as having beneficial ownership over the Ordinary Shares they own or have the right to acquire within 60 days, as well as Ordinary Shares for which they have the right to vote or dispose of such securities. Also in accordance with SEC rules, for purposes of calculating percentages of beneficial ownership, Ordinary Shares, which a person has the right to acquire within 60 days of the date of this prospectus, are included both in that person’s beneficial ownership as well as in the total number of Ordinary Shares issued used to calculate that person’s percentage ownership but not for purposes of calculating the percentage for other persons. In some cases, the same ordinary shares are reflected more than once in the table below because more than one holder may be deemed the beneficial owner of the same Ordinary Shares.

We cannot advise you as to whether the Selling Securityholders will in fact sell any or all of such securities. In addition, the Selling Securityholders may sell, transfer or otherwise dispose of, at any time and from time to time, the Ordinary Shares in transactions exempt from the registration requirements of the Securities Act after the date of this prospectus, subject to applicable law.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain material U.S. federal income tax considerations to U.S. Holders and Non-U.S. Holders (each as defined below) of the ownership and disposition of Ordinary Shares. This discussion applies only to Ordinary Shares that are held as “capital assets” within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment).

The following does not purport to be a complete analysis of all potential tax considerations arising in connection with the ownership and disposal of Ordinary Shares. The effects and considerations of other U.S. federal tax laws, such as estate and gift tax laws, alternative minimum or Medicare contribution tax consequences and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Code, Treasury regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect the tax consequences discussed below. Tritium has not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS will not take or a court will not sustain a contrary position to that discussed below regarding the tax consequences discussed below.

This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of Ordinary Shares that is for U.S. federal income tax purposes:

19

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds Ordinary Shares, the tax treatment of an owner of such entity will depend on the status of the owners, the activities of the entity or arrangement and certain determinations made at the partner level. Accordingly, entities or arrangements treated as partnerships for U.S. federal income tax purposes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THE U.S. FEDERAL INCOME TAX CONSEQUENCES APPLICABLE TO HOLDERS OF ORDINARY SHARES WILL DEPEND ON EACH HOLDER’S PARTICULAR TAX CIRCUMSTANCES. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, AND LOCAL, AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES TO YOU, IN LIGHT OF YOUR PARTICULAR INVESTMENT OR TAX CIRCUMSTANCES, OF ACQUIRING, HOLDING, AND DISPOSING OF ORDINARY SHARES.

U.S. Holders

Distributions on Ordinary Shares

If Tritium makes distributions of cash or property on the Ordinary Shares, the gross amount of such distributions (including any amount of foreign taxes withheld) will be treated for U.S. federal income tax purposes first as a dividend to the extent of its current and accumulated earnings and profits (as determined for U.S. federal income tax purposes), and then as a tax-free return of capital to the extent of the U.S. Holder’s tax basis, with any excess treated as capital gain from the sale or exchange of the shares. Because Tritium does not expect to provide calculations of its earnings and profits under U.S. federal income tax principles, a U.S. Holder should expect all cash distributions to be reported as dividends for U.S. federal income tax purposes. Any dividend will not be eligible for the dividends received deduction allowed to corporations in respect of dividends received from U.S. corporations.

Subject to the discussions below under “—Passive Foreign Investment Company Rules,” dividends received by certain non-corporate U.S. Holders (including individuals) may be “qualified dividend income,” which is taxed at the lower applicable long-term capital gains rate, provided that:

U.S. Holders should consult their own tax advisors regarding the availability of the lower rate for dividends paid with respect to Ordinary Shares. Subject to certain exceptions, dividends on Ordinary Shares will constitute foreign source income and generally passive income for foreign tax credit limitation purposes.

20

Sale, Exchange, Redemption or Other Taxable Disposition of Ordinary Shares

Subject to the discussion below under “ —Passive Foreign Investment Company Rules,” a U.S. Holder generally will recognize gain or loss on any sale, exchange, redemption or other taxable disposition of Ordinary Shares in an amount equal to the difference between (i) the amount realized on the disposition and (ii) such U.S. Holder’s adjusted tax basis in such Ordinary Shares. Any gain or loss recognized by a U.S. Holder on a taxable disposition of Ordinary Shares generally will be capital gain or loss. A non-corporate U.S. Holder, including an individual, who has held the Ordinary Shares for more than one year generally will be eligible for reduced tax rates for such long-term capital gains. The deductibility of capital losses is subject to limitations.

Any such gain or loss recognized generally will be treated as U.S. source gain or loss. U.S. Holders are urged to consult their own tax advisor regarding the ability to claim a foreign tax credit and the application of the Treaty to such U.S. Holder’s particular circumstances.

Passive Foreign Investment Company Rules

The treatment of U.S. Holders of Ordinary Shares could be materially different from that described above, if Tritium is treated as a PFIC for U.S. federal income tax purposes. A non-U.S. entity treated as a corporation for U.S. federal income tax purposes generally will be a PFIC for U.S. federal income tax purposes for any taxable year if either (1) at least 75% of its gross income for such year is passive income or (2) at least 50% of the value of its assets (generally based on an average of the quarterly values of the assets) during such year is attributable to assets that produce passive income or are held for the production of passive income. For this purpose, Tritium will be treated as owning its proportionate share of the assets and earning its proportionate share of the income of any other entity treated as a corporation for U.S. federal income tax purposes in which Tritium owns, directly or indirectly, 25% or more (by value) of the stock. Based on the current and anticipated composition of the income, assets and operations of Tritium and its subsidiaries, Tritium does not believe it will be treated as a PFIC for the current taxable year.

However, whether we or any of our subsidiaries are a PFIC for any taxable year is a factual determination that depends on, among other things, the composition of our income and assets, our market value and the market value of our subsidiaries’ shares and assets. Changes in the composition of our income or asset may cause us to be or become a PFIC for the current or subsequent taxable years. In addition, whether we are treated as a PFIC for U.S. federal income tax purposes is determined annually after the close of each taxable year and, thus, is subject to significant uncertainty. Moreover, the application of the PFIC rules is subject to uncertainty in several respects, and we cannot assure you that the IRS will not take a contrary position or that a court will not sustain such a challenge by the IRS. Accordingly, there can be no assurances that we will not be treated as a PFIC for the current taxable year or in any future taxable year.

Under the PFIC rules, if Tritium were considered a PFIC at any time that a U.S. Holder owns Ordinary Shares, Tritium would continue to be treated as a PFIC with respect to such U.S. Holder’s investment unless (i) it ceased to be a PFIC and (ii) the U.S. Holder made a “deemed sale” election under the PFIC rules. If such election is made, a U.S. Holder will be deemed to have sold its Ordinary Shares at their fair market value on the last day of the last taxable year in which Tritium is classified as a PFIC, and any gain from such deemed sale would be subject to the consequences described below. After the deemed sale election, the Ordinary Shares with respect to which the deemed sale election was made will not be treated as shares in a PFIC unless Tritium subsequently becomes a PFIC.

For each taxable year that Tritium is treated as a PFIC with respect to a U.S. Holder’s Ordinary Shares, the U.S. Holder will be subject to special tax rules with respect to any “excess distribution” (as defined below) received and any gain realized from a sale or disposition (including a pledge) of its Ordinary Shares (collectively the “Excess Distribution Rules”), unless the U.S. Holder makes a valid QEF election or mark-to-market election as discussed below. Distributions received by a U.S. Holder in a taxable year that are greater than 125% of the

21

average annual distributions received during the shorter of the three preceding taxable years or the U.S. Holder’s holding period for the Ordinary Shares will be treated as excess distributions. Under these special tax rules:

Under the Excess Distribution Rules, the tax liability for amounts allocated to taxable years prior to the year of disposition or excess distribution cannot be offset by any net operating losses, and gains (but not losses) realized on the sale of the Ordinary Shares cannot be treated as capital gains, even though the U.S. Holder holds the Ordinary Shares as capital assets.

Certain of the PFIC rules may impact U.S. Holders with respect to equity interests in subsidiaries and other entities which Tritium may hold, directly or indirectly, that are PFICs (collectively, “Lower-Tier PFICs”). There can be no assurance, however, that Tritium does not own, or will not in the future acquire, an interest in a subsidiary or other entity that is or would be treated as a Lower-Tier PFIC. U.S. Holders should consult their own tax advisors regarding the application of the PFIC rules to any of Tritium’s subsidiaries.

If Tritium is a PFIC, a U.S. Holder of Ordinary Shares may avoid taxation under the Excess Distribution Rules described above by making a “qualified electing fund” (“QEF”) election. However, a U.S. Holder may make a QEF election with respect to its Ordinary Shares only if Tritium provides U.S. Holders on an annual basis with certain financial information specified under applicable U.S. Treasury regulations. Because Tritium does not intend to provide such information, however, the QEF Election will not be available to U.S. Holders with respect to Ordinary Shares.

Alternatively, a U.S. Holder of “marketable stock” (as defined below) may make a mark-to-market election for its Ordinary Shares to elect out of the Excess Distribution Rules discussed above if Tritium is treated as a PFIC. If a U.S. Holder makes a mark-to-market election with respect to its Ordinary Shares, such U.S. Holder will include in income for each year that Tritium is treated as a PFIC with respect to such Ordinary Shares an amount equal to the excess, if any, of the fair market value of the Ordinary Shares as of the close of the U.S. Holder’s taxable year over the adjusted basis in the Ordinary Shares. A U.S. Holder will be allowed a deduction for the excess, if any, of the adjusted basis of the Ordinary Shares over their fair market value as of the close of the taxable year. However, deductions will be allowed only to the extent of any net mark-to-market gains on the Ordinary Shares included in the U.S. Holder’s income for prior taxable years. Amounts included in income under a mark-to-market election, as well as gain on the actual sale or other disposition of the Ordinary Shares, will be treated as ordinary income. Ordinary loss treatment will also apply to the deductible portion of any mark-to-market loss on the Ordinary Shares, as well as to any loss realized on the actual sale or disposition of the Ordinary Shares, to the extent the amount of such loss does not exceed the net mark-to-market gains for such Ordinary Shares previously included in income. A U.S. Holder’s basis in the Ordinary Shares will be adjusted to reflect any mark-to-market income or loss. If a U.S. Holder makes a mark-to-market election, any distributions Tritium makes would generally be subject to the rules discussed above under “ —Distributions on Ordinary Shares,” except the lower rates applicable to qualified dividend income would not apply.

The mark-to-market election is available only for “marketable stock,” which is stock that is regularly traded on a qualified exchange or other market, as defined in applicable U.S. Treasury regulations. The Ordinary Shares, which are listed on Nasdaq, are expected to qualify as marketable stock for purposes of the PFIC rules, but there can be no assurance that Ordinary Shares will be “regularly traded” for purposes of these rules. Because a mark-to-market election cannot be made for equity interests in any Lower-Tier PFICs, a U.S. Holder will

22

continue to be subject to the Excess Distribution Rules with respect to its indirect interest in any Lower-Tier PFICs as described above, even if a mark-to-market election is made for Tritium.

If a U.S. Holder does not make a mark-to-market election (or a QEF election) effective from the first taxable year of a U.S. Holder’s holding period for the Ordinary Shares in which Tritium is a PFIC, then the U.S. Holder generally will remain subject to the Excess Distribution Rules. A U.S. Holder that first makes a mark-to-market election with respect to the Ordinary Shares in a later year will continue to be subject to the Excess Distribution Rules during the taxable year for which the mark-to-market election becomes effective, including with respect to any mark-to-market gain recognized at the end of that year. In subsequent years for which a valid mark-to-mark election remains in effect, the Excess Distribution Rules generally will not apply. A U.S. Holder that is eligible to make a mark-to-market with respect to its Ordinary Shares may do so by providing the appropriate information on IRS Form 8621 and timely filing that form with the U.S. Holder’s tax return for the year in which the election becomes effective. U.S. Holders should consult their own tax advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any Lower-Tier PFICs.

A U.S. Holder of a PFIC may be required to file an IRS Form 8621 on an annual basis. U.S. Holders should consult their own tax advisors regarding any reporting requirements that may apply to them if Tritium is a PFIC.

U.S. Holders are strongly encouraged to consult their tax advisors regarding the application of the PFIC rules to their particular circumstances.

Non-U.S. Holders

The section applies to Non-U.S. Holders of Ordinary Shares. For purposes of this discussion, a Non-U.S. Holder means a beneficial owner (other than a partnership or an entity or arrangement so characterized for U.S. federal income tax purposes) of Ordinary Shares that is not a U.S. Holder, including:

U.S. Federal Income Tax Consequences of the Ownership and Disposition of Ordinary Shares to Non-U.S. Holders

Any (i) distributions of cash or property paid to a Non-U.S. Holders in respect of Ordinary Shares or (ii) gain realized upon the sale or other taxable disposition of Ordinary Shares generally will not be subject to U.S. federal income taxation unless:

Gain or distributions described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

23

Non-U.S. Holders should consult their own tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Information reporting requirements may apply to distributions received by U.S. Holders of Ordinary Shares, and the proceeds received on the sale or other taxable the disposition of Ordinary Shares effected within the United States (and, in certain cases, outside the United States), in each case other than U.S. Holders that are exempt recipients (such as corporations). Backup withholding may apply to such amounts if the U.S. Holder fails to provide an accurate taxpayer identification number (generally on an IRS Form W-9 provided to the paying agent of the U.S. Holder’s broker) or is otherwise subject to backup withholding. Any distributions with respect to Ordinary Shares and proceeds from the sale, exchange, redemption or other disposition of Ordinary Shares may be subject to information reporting to the IRS and possible U.S. backup withholding. U.S. Holders should consult their own tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

Information returns may be filed with the IRS in connection with, and Non-U.S. Holders may be subject to backup withholding on amounts received in respect of, a Non-U.S. Holder’s Ordinary Shares, unless the Non-U.S. Holder furnishes to the applicable withholding agent the required certification as to its non-U.S. status, such as by providing a valid IRS Form W-8BEN, IRS Form W-8BEN-E or IRS Form W-8ECI, as applicable, or the Non-U.S. Holder otherwise establishes an exemption. Distributions paid with respect to Ordinary Shares and proceeds from the sale of other disposition of Ordinary Shares received in the United States by a Non-U.S. Holder through certain U.S.-related financial intermediaries may be subject to information reporting and backup withholding unless such Non-U.S. Holder provides proof an applicable exemption or complies with certain certification procedures described above, and otherwise complies with the applicable requirements of the backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding generally may be credited against the taxpayer’s U.S. federal income tax liability, and a taxpayer may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for a refund with the IRS and furnishing any required information.

MATERIAL AUSTRALIAN TAX CONSIDERATIONS

This section below provides a general summary of the Australian tax considerations generally applicable to Australian resident and non-Australian resident shareholders of Tritium with respect to the ownership and disposition of Tritium Ordinary Shares.

The comments in this section deal only with the Australian taxation implications of the ownership and disposition of Tritium Ordinary Shares if you hold your Tritium Ordinary Shares as investments on capital account.

These comments do not apply to you if you:

The Australian taxation implications of holding and disposing of shares in Tritium will vary depending upon your particular circumstances. Accordingly, it should not be relied upon as taxation advice and you should seek and rely upon your own professional advice before concluding on the particular taxation treatment that will apply to you. Furthermore, the discussion below is based upon the Australian income tax laws, applicable case law, regulations and published rulings, determinations and statement of administrative practice of the Australian Taxation Office as at the date of this filing. During the period of ownership of the Tritium Ordinary Shares by Tritium Shareholders, the taxation laws of Australia, or their interpretation, may change (possibly with retroactive effect).

Tritium, Tritium Australia and Tritium Holdings and their officers, employees, taxation or other advisers do not accept any liability or responsibility in respect of any statement concerning taxation consequences, or in respect of the taxation consequences.

This taxation summary is necessarily general in nature and is not exhaustive of all Australian tax consequences that could apply in all circumstances for Tritium shareholders. It is strongly recommended that each Tritium shareholder seek their own independent professional tax advice applicable to their particular circumstances.

This summary does not constitute financial product advice as defined in the Corporations Act. This summary is confined to certain taxation matters, based on the relevant Australian tax laws in force, established interpretations of that law and understanding of the practice of the relevant tax authority at the date of this summary. This summary does not take into account the tax laws of countries other than Australia.

Australian Resident Shareholders

This section applies to Tritium shareholders who are residents of Australia for income tax purposes and hold their shares as investments on capital account.

Taxation in respect of dividends on Tritium Ordinary Shares

Dividends paid by Tritium on a share should constitute assessable income of an Australian tax resident shareholder. Australia has a franking system wherein dividends can be franked and the shareholder receives a franking credit which effectively represents the corporate tax paid by the company. Dividends can be “fully franked”, “partially franked” or “unfranked” and the maximum franking credit is calculated at the corporate tax rate (currently 30%).

25

Australian Resident Individuals and Complying Superannuation Entities

Australian tax resident shareholders who are individuals or complying superannuation entities should include the dividend in their assessable income in the year the dividend is paid, together with any franking credit attached to that dividend.

Subject to the comments in relation to “Qualified Persons” below, such shareholders should be entitled to a tax offset equal to the franking credit attached to the dividend. The tax offset can be applied to reduce the tax payable on the investor’s taxable income. Where the tax offset exceeds the tax payable on the investor’s taxable income, the investor should be entitled to a tax refund equal to the excess.

To the extent that the dividend is unfranked, an Australian individual shareholder will generally be taxed at their prevailing marginal rate on the dividend received (with no tax offset). Complying Australian superannuation entities will generally be taxed at the prevailing rate for complying superannuation entities on the dividend received (with no tax offset).

Corporate Shareholders

Corporate Tritium shareholders are also required to include both the dividend and the associated franking credits (if any) in their assessable income.

Subject to the comments in relation to “Qualified Persons” below, corporate Tritium shareholders should be entitled to a tax offset up to the amount of the franking credit attached to the dividend.

An Australian resident corporate Tritium shareholder should be entitled to a credit in its own franking account to the extent of the franking credits attached to the dividend received. This will allow the corporate Tritium shareholder to pass on the franking credits to its investor(s) on the subsequent payment of franked dividends.

Excess franking credits received by corporate Tritium shareholders will not give rise to a refund entitlement for a company but can be converted into carry forward tax losses instead. This is subject to specific rules on how the carry forward tax loss is calculated and utilized in future years. For completeness, this tax loss cannot be carried back under the loss carry back tax offset rules introduced in the 2020-21 Federal Budget.

Trusts and Partnerships

Australian tax resident Tritium shareholders who are trustees (other than trustees of complying superannuation entities, which are dealt with above) or partnerships are also required to include any dividends and any franking credits in calculating the net income of the trust or partnership. Where a fully franked or partially franked dividend is received, an Australian resident trust beneficiary that is not under a legal disability and that is presently entitled to a share of the income of the trust estate in the relevant year of income, or the relevant partner in the partnership (as the case may be), may be entitled to a tax offset by reference to the beneficiary’s or partner’s share of the net income of the trust or partnership.

To the extent that the dividend is unfranked, an Australian trustee (other than trustees of complying superannuation entities) or partnerships, will be required to include the unfranked dividend in the net income of the trust or partnership. An Australian resident trust beneficiary that is not under a legal disability and that is presently entitled to a share of the income of the trust estate (and not acting in a capacity as trustee) in the relevant year of income, or the relevant partner in the partnership, will generally be taxed at the relevant prevailing tax rate on their share of the net income of the trust or partnership (with no tax offset).

Additional or alternative considerations may be relevant in relation to shareholders that are trustees of specific categories of trusts under Australian tax law (such as managed investment trusts, AMITs, or public

26

trading trusts). The precise tax consequences for a trustee shareholder are a complex tax issue which requires analysis based on each shareholder’s individual circumstances and the terms of the relevant trust deed. Tritium shareholders should obtain their own tax advice to determine these matters.

Qualified Persons

The benefit of franking credits can be denied where a Tritium shareholder is not a “qualified person” in which case the Tritium Shareholder will not be able to include an amount for the franking credits in their assessable income and will not be entitled to a tax offset.

Broadly, to be a qualified person, a Tritium shareholder must satisfy the holding period rule and, if necessary, the related payment rule. The holding period rule requires a Tritium shareholder to hold the shares “at risk” for at least 45 days continuously during the qualification period—starting from the day after acquisition of the shares and ending 45 days after the shares become ex-dividend where there is no relevant “related payment”—in order to qualify for franking benefits.

This holding period rule is subject to certain exceptions, including where the total franking offsets of an individual in a year of income do not exceed A$5,000.

Whether you are qualified person is a complex tax issue which requires analysis based on each shareholder’s individual circumstances. Tritium shareholders should obtain their own tax advice to determine if these requirements have been satisfied.

Capital Gains Tax (“CGT”) Implications

Disposal of Shares

For Australian tax resident Tritium shareholders, who hold their Tritium Ordinary Shares on capital account, the future disposal of Tritium Ordinary Shares will give rise to a CGT event at the time which the legal and beneficial ownership of the Tritium Ordinary Shares are disposed of. Tritium shareholders will derive a capital gain on the disposal of their shares in Tritium to the extent that the capital proceeds exceed the cost base of their Tritium Ordinary Shares.

A capital loss will be made where the capital proceeds are less than the reduced cost base of their Tritium Ordinary Shares. Where a capital loss is made, capital losses can only be offset against capital gains derived in the same or later incomes years. They cannot be offset against ordinary income nor carried back to offset net capital gains arising in earlier income years. Capital losses may be carried forward to future income years subject to the satisfaction of the Australian loss testing provisions.

Capital Proceeds

The capital proceeds should be equal to any consideration received by the Tritium shareholder in respect to the disposal of their Tritium Ordinary Shares.

Cost base of Tritium Ordinary Shares

The cost base of a Tritium ordinary share will generally be equal to the cost of acquiring the Tritium ordinary share, plus any incidental costs of acquisition and disposal (i.e. brokerage costs and legal fees). However, to the extent that a roll-over was obtained in relation to the acquisition of the Tritium Ordinary Shares under the Australian scrip for scrip rules, the cost base should be equal to the inherited cost base of the pre-existing shares (i.e. the original interests).

27

CGT Discount

The CGT discount may apply to Tritium shareholders that are Australian tax resident individuals, complying Australian superannuation funds or trusts, who have held, or are taken to have held, their Tritium Ordinary Shares for at least 12 months (not including the date of acquisition or date of disposal) at the time of the disposal of their Tritium Ordinary Shares.

The impact of the scrip for scrip rollover provisions on the holding period should be considered at an individual shareholder level. However, it is expected that the acquisition date of the Tritium Ordinary Shares for the purposes of the CGT discount should be the acquisition date of the Tritium shareholder’s pre-existing shares.

The CGT discount is:

The CGT discount is not available to Tritium shareholders that are companies.

If a Tritium shareholder makes a discounted capital gain, any current year and/or carried forward capital losses will be applied to reduce the undiscounted capital gain before the relevant CGT discount is applied. The resulting amount is then included in the Tritium shareholder’s net capital gain for the income year and included in its assessable income.

The CGT discount rules relating to trusts are complex. Subject to certain requirements being satisfied, the capital gain may flow through to the beneficiaries in that trust, who will assess the eligibility for the CGT discount in their own right. Accordingly, we recommend trustees seek their own independent advice on how the CGT discount applies to the trust and its beneficiaries.

Non-Australian Resident Shareholders

This section applies to Tritium shareholders who are not residents of Australia for income tax purposes and hold their shares as investments on capital account.

Taxation in Respect of Dividends on Tritium Ordinary Shares

Non-Australian resident Tritium shareholders who do not have a permanent establishment in Australia should not be subject to Australian income tax but may be subject to Australian dividend withholding tax on their Tritium dividends.

Franked Dividends

As outlined above, Australia has a franking system wherein dividends can be franked and Australian resident shareholders receive a franking credit which effectively represents the corporate tax paid by the underlying company (i.e. Tritium). Dividends can be “fully franked”, “partially franked” or “unfranked”.

Dividends received by non-Australian resident Tritium shareholders which are franked should not be subject to Australian dividend withholding tax to the extent of the franking (i.e. if the dividend if fully franked, it should not be subject to Australian dividend withholding tax at all). However, refunds of franking credits are not available to non-Australian resident shareholders.

28

Dividends Attributable to Conduit Foreign Income

Non-Australian resident Tritium shareholders should not be subject to Australian dividend withholding tax where Tritium pays an unfranked dividend out of income which Tritium has declared to be conduit foreign income (“CFI”). Generally, CFI would include amounts received by Tritium that are attributable to dividends received from foreign subsidiaries which are treated as non-assessable non-exempt income for Australian tax purposes.

Unfranked Dividends

Non-Australian resident Tritium shareholders should generally be subject to Australian dividend withholding tax to the extent of the unfranked component of any dividends received that are not declared to be CFI. Australian dividend withholding tax is imposed at a flat rate of 30% on the amount of the dividend that is unfranked unless the Tritium shareholder is a tax resident of a country that has a double tax treaty (“DTT”) with Australia. In the event the Tritium shareholder is otherwise able to rely on the DTT, the rate of Australian dividend withholding tax may be reduced (typically to 15%), depending on the terms of the DTT.

CGT Implications

Non-Australian resident Tritium shareholders who do not have a permanent establishment in Australia should not be subject to Australian CGT.

General Australian Tax Matters

This section applies to both Australian resident and non-Australian resident Tritium shareholders.

GST

The acquisition or disposal of Tritium Ordinary Shares by a shareholder (who is registered or required to be registered for GST) will be classified as a “financial supply” for Australian GST purposes. Accordingly, Australian GST will not be payable in respect of amounts paid for the acquisition or disposal of Tritium Ordinary Shares.

No GST should be payable in respect of dividends paid to Tritium shareholders.

Subject to certain requirements, there may be a restriction on the entitlement of Tritium shareholders registered for GST to claim an input tax credit for any GST incurred on costs associated with the acquisition or disposal of Tritium Ordinary Shares (e.g. lawyer’s and accountants’ fees).

Stamp Duty

No stamp duty should be payable on the acquisition of Tritium Ordinary Shares.

As used herein, “Selling Securityholders” includes donees, pledgees, transferees or other successors-in-interest (as a gift, pledge, partnership distribution or other non-sale related transfer) selling securities received after the date of this prospectus from the Selling Securityholders. We have registered the securities covered by this prospectus for offer and sale so that those securities may be freely sold to the public by the Selling Securityholders. Registration of the securities covered by this prospectus does not mean, however, that those securities necessarily will be offered or resold by the Selling Securityholders. The Selling Securityholders will act independently of us in making decisions with respect to the timing, manner and size of each sale.

Sales of the securities offered hereby may be effected by the Selling Securityholders from time to time in one or more types of transactions (which may include block transactions), including but not limited to, on Nasdaq at prevailing market prices, in negotiated transactions, through put or call options transactions relating to the securities offered hereby, through short sales of the securities offered hereby, or a combination of such methods of sale. Such transactions may or may not involve brokers or dealers. In effecting sales, brokers or dealers engaged by the Selling Securityholder may arrange for other brokers or dealers to participate. Broker-dealer transactions may include purchases of the securities by a broker-dealer as principal and resales of the securities by the broker-dealer for its account pursuant to this prospectus, ordinary brokerage transactions or transactions in which the broker-dealer solicits purchasers. Such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the Selling Securityholders and/or the purchasers of the securities offered hereby for whom such broker-dealers may act as agents or to whom they sell as principal, or both (which compensation as to a particular broker-dealer might be in excess of customary commissions). Any broker-dealers participating in the distribution of the securities covered by this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions received by any of those broker-dealers may be deemed to be underwriting commissions under the Securities Act. The Selling Securityholders have advised us that they have not entered into any agreements, understandings or arrangements with any broker-dealers regarding the sale of the securities covered by this prospectus.

In addition, a Selling Securityholder that is an entity may elect to make a pro rata in-kind distribution of securities to its members, partners or shareholders pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or shareholders would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

There can be no assurance that the Selling Securityholders will sell all or any of the securities offered by

this prospectus. In addition, the Selling Securityholders may also sell securities under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration, rather than under this prospectus.

The Selling Securityholders have the sole and absolute discretion not to accept any purchase offer or make any sale of securities if they deem the purchase price to be unsatisfactory at any particular time.

The Selling Securityholders also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors-in-interest will be the selling beneficial owners for purposes of this prospectus. Upon being notified by a Selling Securityholder that a donee, pledgee, transferee, other successor-in-interest intends to sell our securities, we will, to the extent required, promptly file a supplement to this prospectus to name specifically such person as a Selling Securityholder.

Upon our being notified by any Selling Securityholder that any material arrangement has been entered into with a broker-dealer for the sale of securities offered hereby through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing:

The Selling Securityholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of the securities offered hereby or of securities convertible into or exchangeable for such securities in the course of hedging positions they assume with the Selling Securityholders. The Selling Securityholders may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealers or other financial institutions of the securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as amended or supplemented to reflect such transaction).

A Selling Securityholder may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with those derivatives, the third parties may sell the Securities covered by this prospectus and the applicable prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by any Selling Securityholder or borrowed from any Selling Securityholder or others to settle those sales or to close out any related open borrowings of stock, and may use securities received from any Selling Securityholder in settlement of those derivatives to close out any related open borrowings of stock. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement (or a post-effective amendment). In addition, any Selling Securityholder may otherwise loan or pledge the Securities to a financial institution or other third party that in turn may sell the Securities short using this prospectus. Such financial institution or other third party may transfer its economic short position to investors in our securities or in connection with a concurrent offering of other securities.

To the extent required, we will use our best efforts to file one or more supplements to this prospectus to describe any material information with respect to the plan of distribution not previously disclosed in this prospectus or any material change to such information.

The Selling Securityholders have agreed to indemnify us in certain circumstances against certain liabilities, including certain liabilities under the Securities Act. The Selling Securityholders may indemnify any broker or underwriter that participates in transactions involving the sale of the securities against certain liabilities, including liabilities arising under the Securities Act.

ENFORCEABILITY OF CIVIL LIABILITIES AND AGENT FOR SERVICE OF PROCESS IN THE

UNITED STATES

We are a public limited company organized under the laws of Australia. As a result, the rights of holders of our Ordinary Shares will be governed by Australian law and our constitution. The rights of shareholders under Australian law may differ from the rights of shareholders of companies incorporated in other jurisdictions. A substantial amount of our assets are located outside the United States. As a result, it may be difficult for investors to enforce in the United States judgments obtained in U.S. courts against us based on the civil liability provisions of the U.S. securities laws. It is doubtful whether courts in Australia will enforce judgments obtained in other jurisdictions, including the United States, against us or our directors or officers under the securities laws of those jurisdictions or entertain actions in Australia against us or our directors or officers under the securities laws of other jurisdictions.

Our registered address in Australia is c/o Tritium DCFC Limited, 48 Miller Street, Murarrie, QLD 4172, Australia.

We have irrevocably appointed Cogency Global Inc. as our agent to receive service of process in any action against us in any U.S. federal or state court arising out of this offering or any purchase or sale of securities in connection with this offering. The address of our agent is 122 E 42nd St., 18th Floor, New York, New York 10168.

Our authorized representative in the United States for this offering as required pursuant to Section 6(a) of the Securities Act is Cogency Global Inc., 22 East 42nd Street, 18th Floor New York, NY 10168.
