Overview



Our mission is to be the leading provider of electrified powertrain solutions
for the commercial vehicle industry. Our goal is to reduce the carbon intensity
and the greenhouse gas ("GHG") emissions of the transportation sector by
providing hybrid and range-extending electric powertrain solutions for Class 8
semi-trucks at the lowest total cost of ownership ("TCO"). Throughout our
product offerings, we utilize our battery systems, control software and data
analytics, combined with fully integrated electric motors and power electronics,
to produce electrified powertrain systems.

We currently offer two different product lines: a Hybrid system which is
designed as an add-on to electric powertrains on trucks which can augment power
needs or potentially save on fuel costs, and the Hypertruck ERX which is a
complete powertrain option that is fully electric and leverages an onboard
generator to recharge the batteries as the vehicle is in operation. By reducing
both GHG emissions and TCO, our environmentally conscious solutions support our
customers' pursuit of their sustainability and financial objectives.

We are currently selling the Hybrid system and are developing our Hypertruck ERX
electrified powertrain system for Class 8 semi-trucks. Our Hybrid systems have
been installed in low volumes on our initial customers' commercial vehicles.
Across these customer installations and over the entire Hyliion fleet, we have
accumulated millions of real-world road miles on Class 8 semi-trucks. Our Hybrid
system can either be installed on a new vehicle prior to entering fleet service
or retrofit to an existing in-service vehicle. The Hypertruck ERX system
leverages the experience and operating data from our Hybrid systems to offer a
solution to replace the traditional diesel or compressed natural gas ("CNG")
powertrain installed in new vehicles.

The Hypertruck ERX powertrain, which functions as an electric range-extender, is
addressing the market needs of having a fully electric drive truck that can
travel long distance between refuels and can leverage existing natural gas
infrastructure. Our Hypertruck ERX systems are designed to have their batteries
recharged by an onboard CNG generator. Our Hypertruck ERX system can offer
commercial vehicle owners and operators a net carbon negative capable
electrified powertrain option, when
                                       13

using renewable natural gas ("RNG"). We believe CNG/RNG is the correct fuel
source to begin with, but there are other fuels that will become available to
address the climate change initiative, including hydrogen. We have showcased a
multistage roadmap that starts with utilizing a CNG/RNG generator and evolves
into offering hydrogen-based solutions as well. The Hypertruck platform is
designed to be fuel agnostic while the rest of the electric powertrain can
remain the same. We plan to initially release the Hypertruck ERX CNG solution,
following with the release of a fuel agnostic capable generator ("KARNO"
generator) and a hydrogen fuel cell generator for the Hypertruck platform in the
future.

CNG fueled battery recharging is preferable today due to both the current
comparable cost of fuels and existing availability of CNG infrastructure. Class
8 semi-trucks can currently be refueled with CNG through existing,
geographically diverse and third-party accessible natural gas refueling stations
established across North America. Globally, RNG, CNG and liquified natural gas
("LNG") are used widely for land-based transport and trucking and we believe
there are established, geographically diverse and third-party accessible
stations available in certain areas that may be leveraged in connection with the
use of our electrified powertrain solutions in the future. We believe there is
opportunity for adoption of our electrified powertrain solutions across Europe
and other countries around the globe. This existing and accessible
infrastructure will significantly reduce the buildout time and cost required to
utilize our Hypertruck ERX system as compared to other proposed potential
electrified solutions.

Our Hybrid and Hypertruck ERX systems are designed to be able to be installed on
most major Class 8 semi-trucks in the long term, which will give our customers
the flexibility to continue using their preferred vehicle brands and maintain
their existing fleet maintenance and operations strategies. Our early Hybrid
system deployments include leaders in the transportation and logistics sector.
We are focusing our initial marketing efforts on large fleet operators as well
as companies committed to reducing the overall environmental impact and fuel
costs of their owned and operated trucking fleets.

In September 2022 we acquired assets including new hydrogen and fuel agnostic
capable generator technology from General Electric Company's GE Additive
business. The KARNO generator emerged out of GE's long-running R&D investments
in metal additive manufacturing across multiple industries and in areas such as
generator thermal and performance design. Initial testing indicates the KARNO
generator is expected to comply with all current and foreseeable emissions
standards, specifically from the California Air Resources Board ("CARB") and the
Environment Protection Agency ("EPA"), even when utilizing conventional fuels.
The technology is expected to achieve a meaningful efficiency improvement over
today's conventional generators and could be more efficient than most available
fuel cells. These efficiency improvements should, in turn, enable fuel cost
reductions and improved vehicle range. The technology should also provide for
significant reductions in noise, vibration, moving parts and maintenance as
compared to current combustion engines. The KARNO power system is expected to be
capable of operating on over 20 different fuels including hydrogen, natural gas,
propane, ammonia and conventional fuels. The technology uses heat to drive a
sealed linear generator to produce electricity. The heat is produced by reacting
fuels through flameless oxidation or other heat sources including renewables.

Key Factors Affecting Operating Results



We believe that our performance and future success depend on several factors
that present significant opportunities for us but also pose risks and
challenges, including but not limited to those discussed below and referenced in
Item 1A "Risk Factors."

Successful Commercialization of Our Drivetrain Solutions



Our Hybrid system officially launched, and our first early development
Hypertruck ERX showcase unit was unveiled, on August 31, 2021 at the ACT Expo in
Long Beach, California. Compared to previous Hyliion systems, the Hybrid system
offers fleets a lighter solution that is easier to install, service and operate.
The Hybrid system draws upon the real-world feedback we have received from
customers and the millions of miles logged with the previous system. Due to
shortages of various components caused by global supply chain disruptions, we
are experiencing longer delivery times for a portion of the orders we have
received on new Hybrid systems. In addition, we continually assess the potential
demand impact for the Hybrid system offering in light of recent changes within
the competitive landscape.

In November 2021, we began our Hypertruck ERX roadshow, which consists of
numerous technology fleet experiences focused on demonstrating the features and
benefits of the electric powertrain firsthand. The roadshow consists of "Ride
and Drive" events and in-depth product education of the Hypertruck ERX's
features and benefits, including how it enables fleet decarbonization goals
while also reducing total cost of ownership. Our development timeline has been
extended to allow for design verification and testing inclusive of critical
summer and winter seasons, as well as the accumulation of up to one million
miles prior to production. We expect to complete design verification and begin
initial controlled fleet trials by the end of 2022.

There have been ongoing shortages in the transportation industry supply chain
including semiconductors as well as several other key components. These supply
chain challenges have been especially prominent in the trucking industry, and
one of the impacts has been significantly extended lead times for ordering new
trucks. Fleets are experiencing lead times on new truck purchases that extend
out for delivery into 2023. We placed orders with Peterbilt for all chassis
needed in 2022 earlier this year and are securing build slots for the 2023
calendar year in an effort to mitigate future potential supply chain impacts to
our Hypertruck ERX development schedule. We continue to work closely with our
current supply base to improve delivery of
                                       14

components for the quarters ahead and are diligently seeking alternative sources
of supply for components that meet our technical specifications with shorter
lead times.

In late 2023, we plan to first release the Hypertruck ERX powertrain, leveraging
a natural gas engine as the onboard generator. In the years following, we plan
to release the Hypertruck KARNO, our fuel agnostic variant, as phase two in the
Hyliion journey to a hydrogen-based future. We will also explore other adjacent
markets to leverage the KARNO technology for cost savings and emissions
reductions.

We anticipate that a substantial portion of our capital resources and efforts in
the near future will be focused on the continued development and
commercialization of our drivetrain solutions. The amount and timing of our
future funding requirements, if any, will depend on many factors, including the
pace and results of our research and development efforts, as well as factors
that are outside of our control.

Customer Demand



We have deployed demonstration Hybrid systems to certain early adopters who we
expect to become customers in the future, including leaders in the
transportation and logistics sector as well as companies committed to reducing
the overall environmental impact and fuel costs of their owned and operated
trucking fleets. Further, we began selling the Hybrid system in the fourth
quarter of 2021.

In 2021, we announced our Hypertruck Innovation Council, which consists of some
of the largest fleets who will be assisting us along the development journey and
will have been among the first to experience the Hypertruck ERX through our
"Ride and Drive" events. The successful launch program and deployment of the
Hypertruck ERX met with positive feedback from customer operations teams and
drivers and generated further interest in the Hypertruck ERX solution and
longer-term commercial relationships with us.

The Inflation Reduction Act of 2022 was signed into law in August 2022, under
which the Hypertruck ERX will qualify fleets to receive a 30% tax credit up to
$40,000 per vehicle adopted. We expect this to drive further interest in and
demand for the Hypertruck ERX.

with our Hybrid products. We continue to pursue the sale of both Hybrid systems
as well as complete vehicles installed with our Hybrid system.

Cost of Revenues



Cost of revenues increased $2.9 million in the current quarter, driven by costs
associated with sales of Hybrid systems. We expect a difference in timing
between recognition of revenues and cost of revenues due to write-down of
inventory to net realizable value in periods prior to sales. The increase in
cost of revenues includes:

•Inventory write-downs of $2.3 million attributable to inventory on hand that had a cost higher than its net realizable value;

•Class 8 semi-truck cost of $0.2 million; and

•Warranty costs of $0.2 million for estimated costs to administer and maintain the warranty program for labor, transportation and parts, excluding any contribution from vendors.

Cost of Revenues



Cost of revenues increased $7.2 million in the current nine months, driven by
costs associated with sales of Hybrid systems. We expect a difference in timing
between recognition of revenues and cost of revenues due to write-down of
inventory to net realizable value in periods prior to sales. The increase in
cost of revenues includes:

•Inventory write-downs of $5.5 million attributable to inventory on hand that had a cost higher than its net realizable value;

•Class 8 semi-truck cost of $0.2 million; and

•Warranty costs of $0.5 million for estimated costs to administer and maintain the warranty program for labor, transportation and parts, excluding any contribution from vendors.

Research and Development

Research and development expenses increased $47.7 million in the current nine months primarily due to:



•$28.8 million related to hydrogen and fuel agnostic capable generator
technology ("KARNO") acquired in September 2022 from General Electric Company's
GE Additive business to develop and commercialize the fuel agnostic Hypertruck
KARNO; and

•An increase of $17.9 million for the design and testing of our Hypertruck
system including an increase in expenses related to components, services and
personnel as we build out our engineering, operations and supply chain teams and
associated capabilities.

Selling, General and Administrative

Selling, general, and administrative expenses increased $6.1 million in the current nine months primarily due to:



•An increase in personnel and benefits of $4.4 million and software costs of
$1.6 million as we continue to grow our sales and other functions, including
impacts from the departure of our prior Chief Financial Officer; and

•An increase of $1.0 million for legal and professional services and other; partially offset by

•A decrease of $0.2 million for marketing and advertising.

Other Income

Total other income increased $2.4 million in the current nine months primarily due to interest income on investments.

Liquidity and Capital Resources



At September 30, 2022, our current assets were $394.0 million, consisting
primarily of cash and cash equivalents of $154.2 million, short-term investments
of $232.9 million and prepaid expenses of $5.9 million. Our current liabilities
were $16.8 million primarily comprised of accounts payable, accrued expenses and
operating lease liabilities.

We believe the credit quality and liquidity of our investment portfolio at
September 30, 2022 is strong and will provide sufficient liquidity to satisfy
operating requirements, working capital purposes and strategic initiatives. The
unrealized gains and losses of the portfolio may remain volatile as changes in
the general interest environment and supply and demand fluctuations of the
securities within our portfolio impact daily market valuations. To mitigate the
risk associated with this market volatility, we deploy a relatively conservative
investment strategy focused on capital preservation and liquidity whereby no
investment security may have a final maturity of more than 36 months from the
date of acquisition or a weighted average maturity exceeding 18 months. Eligible
investments under the Company's investment policy bearing a minimum credit
rating of A1, A-1, F1 or higher for short-term investments and A2, A, or higher
for longer-term investments include money market funds, commercial paper,
certificates of deposit and municipal securities. Additionally, all of our debt
securities are classified as held-to-maturity as we have the intent and ability
to hold these investment securities to maturity, which minimizes any realized
losses that we would recognize prior to maturity. However, even with this
approach we may incur investment losses as a result of unusual or unpredictable
market developments, and we may experience reduced investment earnings if the
yields on investments deemed to be low risk remain low or decline further due to
unpredictable market developments. In addition, these unusual and unpredictable
market developments may also create liquidity challenges for certain of the
assets in our investment portfolio.

Based on our past performance, we believe our current assets will be sufficient
to continue and execute on our business strategy and meet our capital
requirements for the next twelve months. Our primary short-term cash needs are
Hypertruck ERX product development costs and components purchased to support the
stated of production, operating expenses and production and related costs of
Hybrid systems. We plan to stay asset-light and utilize third parties to perform
assembly and manufacturing at scale.

We expect to continue to incur net losses in the short term, as we continue to
execute on our strategic initiatives by (i) completing the development and
commercialization of the electrified drive systems for Class 8 semi-trucks, (ii)
scaling the Company's operations to meet anticipated demand and (iii) hiring
personnel. Further, we plan to develop and commercialize the fuel agnostic
Hypertruck KARNO with an anticipated commercial launch a few years after the
Hypertruck ERX. However, actual results could vary materially and negatively as
a result of a number of factors including, but not limited to, those discussed
in Part II, Item 1A. "Risk Factors."

During the periods presented, we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities, which were established for the purpose of facilitating off-balance sheet arrangements.

Critical Accounting Policies and Estimates



In preparing our condensed consolidated financial statements, we applied the
same critical accounting policies as described in our 2021 Annual Report,
supplemented with those below, that affect judgments and estimates of amounts
recorded for certain assets, liabilities, revenues and expenses.
                                       19

Acquisitions



To determine whether acquisitions should be accounted for as a business
combination or as an asset acquisition, we make certain judgments which include
assessing whether the acquired set of activities and assets meet the definition
of a business. If the acquired set of activities and assets meets the definition
of a business, assets acquired and liabilities assumed are required to be
recorded at their respective fair values as of the acquisition date with the
excess of the purchase price over the fair value of the acquired net assets
recorded as goodwill. If the acquired set of activities and assets does not meet
the definition of a business, the transaction is recorded as an acquisition of
assets and, therefore, any acquired in-process research and development
("IPR&D") that does not have an alternative future use is charged to expense at
the acquisition date, and no goodwill is recorded.

The judgments made in determining estimated fair values of assets acquired and
liabilities assumed in a business combination or asset acquisition, as well as
estimated asset lives, can materially affect our consolidated results of
operations. All assets acquired in 2022 were valued using level 3 inputs with
property and equipment valued using a cost approach and IPR&D valued using an
income approach based on management's projections. The fair values of assets,
including acquired IPR&D, are determined using information available near the
acquisition date based on estimates and assumptions that are deemed reasonable
by management. Significant estimates and assumptions include, but are not
limited to, probability of technical success, revenue growth, future revenues
and expenses and discount rate.

Revenue Recognition



When a Class 8 semi-truck outfitted with a Hybrid system is resold to a
customer, judgment is required to determine if we are the principal or agent in
the arrangement. We consider factors such as, but not limited to, which entity
has the primary responsibility for fulfilling the promise to provide the
specified good or service, which entity has inventory risk before the specified
good or service has been transferred to a customer and which entity has
discretion in establishing the price for the specified good or service. We have
determined that we are the principal in transactions involving the resale of
Class 8 semi-trucks outfitted with the Hybrid system. We are in early stages of
development, continue to refine our business plans and consider the resale of
Class 8 semi-trucks outfitted with Hybrid systems to constitute ordinary
activities from our ongoing major or central operations.

Should our business plans, estimates or assumptions change, we may record receipts from sales of Class 8 semi-trucks as non-operating income in future periods.
