Tritium Announces Record-Breaking Fourth Quarter and 2021 Results

Company reports second half 2021 sales of $98 million, an increase of 416% year over year; record contracted backlog at year end, representing over 48% of the Company’s 2022 revenue target; and issues formal revenue guidance of $170 million for 2022, consistent with prior forecast.

Tritium announces it is in the final stages of site selection for its new U.S. factory; the Company expects an announcement in the first quarter of 2022 with production expected to start in third quarter 2022.

BRISBANE, Australia, January 4, 2022 – Tritium Holdings Pty Ltd (“Tritium” or the “Company”), a global developer and manufacturer of direct current (“DC”) fast chargers for electric vehicles (“EVs”), today announced record sales, backlog and revenue results for and as of the year ended December 31, 2021, and provided a business update. Except as otherwise indicated or unless the context otherwise requires, all financial figures are in U.S. dollars and references herein to “quarter,” “year,” “2020,” “2021” or “2022” are to the relevant calendar period.

For the three months ended December 31, 2021, Tritium booked revenue of approximately $41 million, equivalent to a last quarter annualized (LQA) run-rate of $164 million, and set a new quarterly record. The Company more than doubled its Q3 2021 revenue, the next largest quarterly revenue in its 19-year operating history, and achieved more than 2.5x revenue compared to the fourth quarter of 2020.

For 2021, revenue was approximately $78 million, which is only slightly lower than the previous forecast of $84 million, due in large part to logistics and supply chain challenges, including delays at the ports of Long Beach and Los Angeles, which delayed certain product deliveries at year end. Tritium expects to record those revenues as products are received by customers in the first quarter of 2022. As reported by CNBC, the twin ports of Long Beach and Los Angeles account for 40% of sea freight entering the United States, and the back-up escalated throughout the year. Tritium has begun to see supply chain constraints ease, with these ports reporting a 33% decline in lingering cargo containers in December 2021 compared to November 2021. The Company expects 2021 EBITDA and Free Cash Flow to be approximately $(39) million and $(43) million, respectively.

Underscoring the record demand for Tritium’s products, sales for 2021 were $141 million, which represents more than a 136% increase over 2020 sales of $60 million. The Company’s sales grew significantly in the second half of 2021 to $98 million, an increase of 416% compared to the second half result of $19 million the previous year.

Tritium believes that this growth in sales substantiates its thesis that DC fast charging infrastructure is rolling out at an accelerating pace to support the rapid shift towards electric vehicles globally. Tritium enters 2022 with the largest year-opening order book in its history. Tritium’s backlog continued to grow throughout 2021, ending at approximately $82 million, an increase of approximately 316% since year end 2020. This backlog is expected to be completely delivered in 2022, and is now expected to account for over 48% of Tritium’s 2022 revenue guidance, or approximately 5 months of forward production capacity at current production levels. Tritium continues to be engaged in a number of additional and potentially high-impact orders under several of its recently announced commercial partnerships and tender wins, and is expanding production capacity to fulfill growing demand in the United States and Europe.

Other recent business highlights include:

Business Combination Update

The special meeting of stockholders of Decarbonization Plus Acquisition Corporation II (NASDAQ: DCRN, DCRNW, DCRNU) (“DCRN”) to approve the proposed business combination with Tritium, among other related matters, is scheduled to be held on Wednesday, January 12, 2022 at 10:00am Eastern time.

Credit Suisse Securities (USA) LLC (“Credit Suisse”) is acting as the exclusive financial advisor to a consortium of certain Tritium shareholders in connection with the business combination between Tritium and DCRN. DCRN engaged Credit Suisse as its lead placement agent and Citi Global Markets (“Citi”) and J.P. Morgan Securities LLC (“JPMorgan”) as placement agents for its PIPE Financing (as defined below). Raymond James & Associates, Inc. (“Raymond James”) is acting as Capital Markets Advisor for DCRN. Citi and JPMorgan are acting as financial advisors to DCRN.

The board of directors of DCRN has unanimously recommended stockholders vote in favor of the proposed business combination, which values Tritium at approximately $1.2 billion. As of market close on Monday, January 3, 2022, based on publicly available information as illustrated in the table below, Tritium continues to be valued at a significant discount to the publicly traded, pure-play EV charging peers.

Tritium believes that its target customers are in the midst of an aggressive and historic build cycle. Unlike many of the alternative investment opportunities in the EV charging category, Tritium’s cash flow profile benefits from revenue realization at the time of sale, paired with associated service and recurring software revenue in the future. In an environment of rising interest rates, Tritium believes this business model will resonate with public equity investors seeking exposure to manufacturers, producers and suppliers to the EV thematic.

Fast chargers are emerging as an essential tool to address range anxiety while also providing drivers with a recharging experience that is most analogous to their refueling experience. Tritium believes its technology-advantaged hardware alongside its growing commitment to the services and software offerings presents a compelling value for charge point operators; forecourt fuel, gas and petrol stations; and retail, restaurant and residential complexes looking to install DC fast chargers. Contribution from those critical categories continued to expand in 2021, and Tritium expects the positive impact from the charging infrastructure and hardware buildout to become increasingly evident in 2023 and 2024 financial results. This strategy is consistent with Tritium’s strategy and customer-serving thesis, and the deepening of the Company’s existing relationships with partners such as Shell and Ionity, in addition to new relationships with partners such as Osprey and Aqua superPower, is validating the position Tritium enjoys in performance, reliability, visual display and modularity relative to competitor offerings.

The Company expects to furnish its consolidated financial statements as of and for the six months ended December 31, 2021 in future filings by Tritium DCFC Limited (“NewCo”) with the U.S. Securities and Exchange Commission (the “SEC”) assuming consummation of the business combination. Figures originally reported in Australian dollars were translated into U.S. dollars for the purposes of this press release using the average AUD/USD foreign exchange rates for historical periods.

No Offer or Solicitation

This document does not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed business combination. This document also does not constitute an offer to sell or exchange, or the solicitation of an offer to buy or exchange, any securities, nor will there be any sale of securities in any states or jurisdictions in which such offer, solicitation, or sale or exchange 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.

Use of Non-GAAP Financial Measures

Tritium has provided in this press release financial information that has not been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”), namely expected EBITDA and Free Cash Flow for the year ended December 31, 2021. The Company uses non-GAAP financial measures internally in analyzing its financial results and believes that the use of these non-GAAP financial measures are useful to investors to evaluate ongoing operating results and trends, and in comparing the Company’s financial results with other companies in its industry, many of which present similar non-GAAP financial measures.

The presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for comparable GAAP financial measures and should be read only in conjunction with the Company’s consolidated financial statements prepared in accordance with GAAP, which NewCo expects to provide in its future filings with the SEC assuming consummation of the business combination. Due to the high variability and difficulty in accurately determining of some of the information to be excluded from EBITDA and Free Cash Flow for the year ended December 31, 2021 as of the date of this press release, together with some of the excluded information not being ascertainable or accessible as of the date of this press release, the Company is unable to accurately 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 EBITDA or Free Cash Flow is included.

EBITDA. Tritium defines EBITDA as net loss before interest income or expense, income tax expense or benefit, and depreciation and amortization.

Free Cash Flow. Tritium defines Free Cash Flow is defined as EBITDA less Capital Expenditures and change in Net Working Capital.

Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures to analyze financial results and trends. In particular, many of the adjustments to Tritium’s GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in its financial results for the foreseeable future. Furthermore, these non-GAAP financial measures are not based on any standardized methodology prescribed by GAAP, and the components that Tritium excludes in its calculation of these non-GAAP financial measures may differ from the components that other companies exclude when they report their non-GAAP financial results. Tritium compensates for these limitations by providing specific information regarding the GAAP amounts excluded from these non-GAAP financial measures. In the future, the Company may also exclude other expenses it determines do not reflect the performance of the Company’s operating results.
