CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

Unless the context otherwise requires, all references to “QuantumScape,” “we,” “us,” “our,” or the “Company” in this Annual Report on Form 10-K (this “Report”) refer to QuantumScape Corporation and its subsidiaries.

The Company makes forward-looking statements in this Report and in documents incorporated herein by reference. All statements, other than statements of present or historical fact included in or incorporated by reference in this Report, regarding the Company’s future financial performance, the development of the Company’s battery technology, as well as the Company’s strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this Report, the words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “prospective,” “should,” “will,” “would,” the negative of such terms, and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations, assumptions, hopes, beliefs, intentions and strategies regarding future events and are based on currently available information as to the outcome and timing of future events. The Company cautions you that these forward-looking statements are subject to risks and uncertainties, including those described in Part I, Item 1A, “Risk Factors” in this Report, most of which are difficult to predict and many of which are beyond the control of the Company and incident to its business. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make.

In addition, forward-looking statements in this Report and in any document incorporated herein by reference should not be relied upon as representing the Company’s views as of any subsequent date, and the Company does not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable laws.

As a result of a number of known and unknown risks and uncertainties, the Company’s actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include those discussed in the section titled “Risk Factors” in this Report and in our other filings with the Securities and Exchange Commission (“SEC”).

TECHNICAL GLOSSARY

Throughout this Annual Report on Form 10-K, we use several technical terms which are explained as follows:

A, B and C samplesThe designation of progressive prototype maturity during the battery cell development process for automotive qualification by OEMs. Delivery of an A sample marks the beginning of the qualification process. Each successive alphabetic designation (e.g., B, C) represents advancement to the next development stage, while each numerical increment (e.g., B0, B1) signifies progress within that stage. The specifications for each sample designation are determined jointly with the OEM.
AnodeThe negative electrode in a battery, serving as the host material for lithium ions during charging
Battery cycle lifeThe number of times a battery can be charged and discharged until its capacity is significantly reduced (e.g. to 70% or 80% of the initial capacity)
Capacity (battery)The amount of charge a battery can store. May be measured in amp-hours (Ah)
CathodeThe positive electrode in a battery
CatholyteThe lithium-ion conductor in the cathode compartment of a battery
DendritesGrowths of lithium metal that can pass through a separator and short circuit the cell
EVElectric vehicle
Energy densityThe amount of energy stored in a battery per unit volume (volumetric energy density which may be measured in Wh/L) or unit mass (specific energy, also known as gravimetric energy density which may be measured in Wh/kg)
ICEInternal combustion engines
LFPLithium-iron-phosphate, a cathode active material
Lithium-ion batteryA conventional battery which uses liquid electrolyte to transport lithium ions between the cathode and anode to charge and discharge the battery
Lithium-metal batteryAdvanced battery technology that uses lithium metal as the anode
NMCNickel-manganese-cobalt, a cathode active material
OEM(s)Original Equipment Manufacturer(s), which in the context of this Report, are companies that design, produce and sell vehicles under their own brand names
Power (battery)The rate at which a battery can be discharged or charged
QSE-5Our first planned product, a ~5 Amp hour solid-state lithium-metal battery cell
SeparatorA material in between the cathode and anode that prevents physical contact between the positive and negative electrodes. Our cell design includes a separator that consists of an inorganic solid ceramic film that has characteristics of both a separator and an electrolyte, and we sometimes refer to our proprietary solid-state electrolyte-separator as “electrolyte-separator”, “solid-state separator”, or “solid-state electrolyte-separator”.
Solid-state batteryNext-generation battery technology that comprises a solid separator
