Q3 2022 Update November 14, 2022 Exhibit 99.1

Disclaimer Forward-Looking Statements This presentation includes certain statements that are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook,” “project,” “will likely result” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. All statements, other than statements of present or historical fact included in this press release, are forward-looking statements, including statements regarding the trajectory and growth of Quanergy's business, Quanergy's customer pipeline, expectations regarding bookings and revenues and the benefit of market fit, repeatability and scale, Quanergy's project with Fabrinet and the expansion of its partner ecosystem and all information included in the section titled “Outlook for 2022”. These forward-looking statements involve significant risks and uncertainties that could cause actual results to differ materially from expected results. Most of these factors are outside Quanergy's control and are difficult to predict. Factors that may cause such differences include, but are not limited to: changes in domestic and foreign business, market, financial, political and legal conditions; the overall level of consumer demand for Quanergy's products; general economic conditions and other factors affecting consumer confidence, preferences, and behavior; disruption and volatility in the global currency, capital, and credit markets; the financial strength of Quanergy's customers; Quanergy's ability to implement its business strategy; changes in governmental regulation, Quanergy's exposure to litigation claims and other loss contingencies; disruptions and other impacts to Quanergy's business, as a result of the COVID-19 global pandemic and government actions and restrictive measures implemented in response; stability of Quanergy's suppliers and the impact of supply chain constraints, as well as consumer demand for its products, in light of disease epidemics and health-related concerns such as the COVID-19 global pandemic; the impact that global climate change trends may have on Quanergy and its suppliers and customers; Quanergy's ability to protect patents, trademarks and other intellectual property rights; any breaches of, or interruptions in, Quanergy's information systems; fluctuations in the price, availability and quality of electricity and other raw materials and contracted products as well as foreign currency fluctuations; Quanergy's ability to utilize potential net operating loss carryforwards; changes in tax laws and liabilities, tariffs, legal, regulatory, political and economic risks; and other risks and uncertainties indicated in Quanergy's filings with the U.S. Securities and Exchange Commission (“SEC”), including under the “Risk Factors” heading of Quanergy's quarterly report on Form 10-Q for the quarters ended September 30, 2022, as filed with the SEC on November 14, 2022. In addition, forward-looking statements reflect Quanergy's expectations, plans or forecasts of future events and views only as of the date of this press release. Quanergy anticipates that subsequent events and developments will cause its assessments to change. However, while Quanergy may elect to update these forward-looking statements at some point in the future, Quanergy specifically disclaims any obligation to do so, except as required by law. Non-GAAP Financial Measures In addition to its results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), Quanergy believes the non-GAAP measures of non-GAAP adjusted gross profit, adjusted EBITDA and free cash flow are useful in evaluating its operating performance. Quanergy calculates non-GAAP adjusted gross profit as gross profit adding back stock-based compensation expense included in cost of goods sold. Quanergy calculates non-GAAP adjusted EBITDA as net loss adding back stock-based compensation expense, depreciation and amortization, interest expense and income, change in fair value of derivative liability, gain on forgiveness of PPP loan, other comprehensive income (net), and income tax provision (benefit). Quanergy believes that non-GAAP adjusted gross profit and non-GAAP adjusted EBITDA may be helpful to investors because they provide consistency and comparability with past financial performance and may be helpful in comparing with other companies, some of which use similar non-GAAP information to supplement their GAAP results. Free cash flow is a non-GAAP financial measure. Management believes, however, that free cash flow is an important financial measure for use in evaluating the Company’s financial performance, as it measures the Company’s ability to generate additional cash from its business operations. Quanergy defines free cash flow as cash flow from operations less capital expenditures. Free cash flow should be considered in addition to, rather than as a substitute for, net loss as a measure of performance or net cash provided by operating activities as a measure of liquidity. Therefore, Quanergy believes it is important to view free cash flow as supplemental to the entire statement of cash flows. The non-GAAP financial information is presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP and may be different from similarly titled non-GAAP measures used by other companies. Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP financial measures are included at the end of this presentation.

Actions Taken to Optimize Cost Structure Quanergy’s Q3 2022 burn rate of $11.6 million is less than half the quarterly burn rate of the LiDAR peer group, which averages $26.0 million Quanergy’s ratio of quarterly burn rate to revenue has decreased during 2022, driven by revenue growth that has exceeded expense growth On October 3, 2022, Quanergy announced a restructuring plan to further reduce operating expenses; management plans for further actions to be implemented in Q4 2022 Quanergy expects further decreases in the burn rate / revenue metric as revenues scale over a more streamlined cost structure QUARTERLY BURN RATE / REVENUE RATIO Note: Burn rate is defined as cash flow used in operations less capex.
