ITEM 1. BUSINESS
Item 1. Business
Overview
Proterra’s mission is to advance electric vehicle technology to deliver the world’s best performing commercial vehicles.
Commercial and industrial fleets are expected to adopt electric vehicles at increasingly higher rates over the next two decades, driven by factors including emissions targets and regulations, and lower operating costs. More than 200,000 new electric buses, medium-duty trucks, and heavy-duty trucks are expected to be sold in the industry by 2030 and approximately 650,000 by 2040 in our core markets of North America and Europe. Assuming average battery capacity per vehicle of 225 kWh for medium-duty trucks, 300 kWh for buses and 750 kWh for heavy-duty trucks, we estimate this could translate into demand for heavy-duty commercial and industrial-scale batteries of approximately 90 GWh in 2030 and approximately 300 GWh in 2040 in such markets. Our business strategy is to capitalize on this opportunity.
In the first quarter of 2023, we announced the appointment of Julian Soell as the Chief Operating Officer of the Company, and Christopher Bailey as Chief Business Officer of the Company, each appointment effective as of March 1, 2023. With these appointments, we consolidated all of our product lines under one Chief Business Officer and all our operations under one Chief Operating Officer, from organizing our business around business groups (called Proterra Transit and Proterra Powered & Energy, respectively) each lead by a President. In addition, we announced workforce restructuring plans designed to improve operational efficiency with the reduction of our workforce by up to twenty five percent or the elimination of approximately 300 jobs and the closure of our City of Industry manufacturing facility by December 31, 2023.
We have three commercial offerings each addressing a critical component of commercial vehicle electrification.
•Proterra Powered & Energy. Proterra Powered products are our proprietary battery systems and electrification solutions for global commercial vehicle original equipment manufacturer (“OEM”) customers serving the Class 3 to Class 8 vehicle segments, including delivery trucks, school buses, and coach buses, as well as construction and mining equipment, and other applications. Proterra Energy products and services offer turnkey fleet-scale, high-power charging solutions and software services, ranging from fleet and energy management software-as-a-service, to fleet planning, hardware, infrastructure, installation, utility engagement, and charging optimization. These solutions are designed to optimize energy use and costs, and to provide vehicle-to-grid functionality.
•Proterra Transit. We design, develop, manufacture, and sell electric transit buses as an OEM for North American public transit agencies, airports, universities, and other commercial transit fleets. Proterra Transit vehicles showcase and validate our electric vehicle technology platform through rigorous daily use by a large group of sophisticated customers focused on meeting the wide-ranging needs of the communities they serve.
Our industry experience, the performance of our transit buses, and compelling total cost of ownership has helped make us the leader in the U.S. electric transit bus market. With over 1,000 electric transit buses delivered, our electric transit buses currently have delivered more than 35 million cumulative service miles spanning a wide spectrum of climates, conditions, altitudes and terrains. From this experience, we have been able to continue to iterate and improve our technology.
Our decade of experience supplying battery electric heavy duty transit buses provided us the opportunity to validate our products’ performance, operational efficiency and maintenance costs with a demanding customer base and helped broaden our appeal as a key electrification solutions supplier to OEMs in other commercial vehicle segments and geographies. Proterra Powered’s strategy is to leverage Proterra Transit’s success in the electric transit bus market and domain expertise to showcase the performance of our technology and demonstrate a strong track record of range and reliability in order to provide our battery systems and electrification solutions to
other commercial vehicle segments. We believe our success in the transit bus market using our battery systems and electrification solutions to power heavy-duty vehicles with better performance and operating characteristics than a diesel-powered bus, all while maintaining a rigorous regular schedule of operation with little tolerance for error, helps demonstrate the broad applicability of our technology to other commercial vehicle segments with similar requirements. We sell our battery systems and electrification solutions using a business development team as well as a channel sales team for certain end markets. These teams work closely with our engineering team to develop optimal electrification solutions for our customers, adapted to their vehicle requirements.
Proterra Powered has partnered with more than a dozen OEMs spanning from Class 3 to Class 8 trucks, several types of buses, and multiple off-highway categories. Through December 31, 2022, Proterra Powered has delivered battery systems and electrification solutions for more than 1,600 vehicles to our OEM partner customers.
In addition, Proterra Energy has established us as a leading commercial vehicle charging solution provider by helping fleet operators fulfill the high-power charging needs of commercial electric vehicles and optimize their energy usage, while meeting our customers’ space constraints and continuous service requirements. As of December 31, 2022, we had installed more than 95 MW of charging infrastructure across North America.
Through December 31, 2022, we have generated the majority of our revenue from Proterra Transit’s sales of electric transit buses, complemented by additional revenue from Proterra Powered’s sales of battery systems and Proterra Energy’s sales and installation of charging systems, as well as from the sale of spare parts and other services provided to customers. As fleet electrification continues to expand beyond buses to trucks and other commercial vehicles, we expect Proterra Powered & Proterra Energy to grow into a significantly larger portion of our overall business and generate a greater portion of revenue. Through December 31, 2022, our chief operating decision maker, the Chief Executive Officer, evaluates Proterra’s results on a consolidated basis for purposes of making decision on allocating resources and assessing financial performance, resulting in a single reportable segment.
We delivered 199, 208, and 170 new transit buses in 2022, 2021, and 2020, respectively. We also delivered 14 and 9 pre-owned buses in 2022 and 2021, respectively. We delivered battery systems for 1,229 vehicles, 273 vehicles, and 107 vehicles in 2022, 2021, and 2020, respectively.
For the years ended December 31, 2022, 2021 and 2020, our total revenue was $309.4 million, $242.9 million, and $196.9 million, respectively. As of December 31, 2022, in aggregate, we have generated revenue of $749.2 million for the past three years. We generated a gross loss of $(24.0) million for the year ended December 31, 2022 and a gross profit of $2.1 million and $7.5 million for the year ended December 31, 2021 and 2020, respectively. We have also invested significant resources in research and development, operations, and sales and marketing to grow our business and, as a result, generated losses from operations of $220.9 million, $127.6 million, and $96.0 million for the years ended December 31, 2022, 2021 and 2020, respectively.

Further, on June 14, 2021, as contemplated by the Merger Agreement, Proterra consummated the Merger, whereby Phoenix Merger Sub merged with and into Legacy Proterra, the separate corporate existence of Phoenix Merger Sub ceasing and Legacy Proterra being the surviving corporation and a wholly owned subsidiary of Proterra. Legacy Proterra was incorporated in Delaware on February 2, 2010, and upon the Merger on June 14, 2021 changed its name to “Proterra Operating Company, Inc.” and continues as a Delaware Corporation.
Our products
We design, manufacture, and sell proprietary battery systems, electrification and charging solutions and fleet and energy management systems purpose-built for commercial vehicles. Our battery systems, electrification and charging solutions and fleet and energy management systems are also used in electric transit buses that we design, sell, and manufacture. Our Proterra Energy business also provides charging infrastructure solutions to simplify the adoption of electric commercial vehicles and improve fleet operations, as well as software services relating to fleet management, remote diagnostics, smart charging and vehicle-to-grid energy management.
Battery system
Our highly modular battery systems meet the needs of a variety of commercial vehicle segments and sizes. We sell our battery packs in two different widths and three different heights depending upon the frame rail length constraints of the vehicle. In addition, each module is available in two different lengths, and three different voltages (25V, 35V and 50V). Modules can be strung in series up to 1,200V within a pack. Packs can be combined up to 16 strings in parallel.
We design, validate, test, and manufacture high-voltage battery packs that are used in our electric transit buses, as well as other commercial vehicle applications. We have designed our batteries based on the core principles of modularity, durability, safety, and scalability.
Our batteries have been designed around standardized form factor cylindrical cells that are produced by numerous global cell manufacturers. Our battery design is flexible to chemistry and manufacturer, allowing us to utilize the best cells commercially available in terms of energy density, cost, cycle life performance, charge rate acceptance, and safety. We have worked with LG Chem Ltd., now LG Energy Solution, to develop cells that are optimized for our applications. Each module contains a proprietary battery monitoring board, and each pack contains a proprietary battery management system, which together monitor the performance of the battery pack and communicate with the vehicle.
We engineered the battery pack with safety and durability as core principles. The battery enclosure is a rugged structure, built using aluminum extrusions and castings, and may include an aluminum base plate to protect the cells. The module and enclosure architecture are designed to be safe in extreme mechanical and environmental abuse scenarios. We internally test our battery cells, modules, and packs to ensure they meet our durability, cycle life performance, and safety and warranty requirements.
Inherent to the mechanical and electrical architecture of our battery modules and battery packs is the flexibility to rapidly reconfigure components for use in various commercial vehicle applications. Battery modules and packs can be connected electrically in a series of strings to increase system voltage up to 1,200V. Additionally, multiple strings can be connected in parallel to enable megawatt-hour-scale battery systems. While our battery system is optimized for commercial vehicle applications, we have also created an architecture with second-life use in mind. For instance, our battery packs are designed to be stackable in order to be deployed with minimal modification in stationary energy storage applications.
We operate a battery research and development laboratory at our Burlingame headquarters, co-located with battery engineering, advanced manufacturing engineering, and manufacturing operations. Capabilities of this lab include mechanical and environmental durability testing, highly accelerated life testing, electrical safety testing, cell lifecycle and safety testing, mechanical abuse testing, and prototype assembly for new applications. Prototype and production variants of our battery products are tested and certified to industry standards, including Society of Automotive Engineers (“SAE”) J2929, as well as proprietary internal test requirements.
Electric drivetrains
A key driver of vehicle performance, and biggest consumer of battery energy, is the drivetrain, which includes the traction motor, inverter, controller, and gearbox. We have partnered with leading engineering and manufacturing companies to offer both single- and dual-motor drivetrains. These are the 275 continuous horsepower ProDrive 2.0 system and the 338 continuous horsepower DuoPower system. Both utilize three-phase, permanent-magnet, liquid-cooled motors. In contrast to internal combustion engines, electric motors provide very
high torque for superior hill-climb ability. Proterra couples this with a multi-speed gearbox to deliver that torque across a wide range of vehicle speeds. These systems provide superior performance to a comparably sized commercial diesel vehicle, and provide a higher ‘regen’ efficiency when the bus is braking. Our drivetrains also have significant advantages over traditional powertrains in weight and serviceability. Our motor weighs 90 kilograms, compared to over 800 kilograms for a typical diesel engine, and may be removed in four hours, compared to 12 hours for a standard diesel engine.
The traction motor inverter is a liquid-cooled power electronics unit that converts high-voltage battery direct-current into AC power required for the desired torque and speed of the traction motor. This unit operates bi-directionally, acting as the control to turn the motor into a regenerative brake, recovering energy back into the battery packs. The drivetrain controller translates the accelerator and brake pedal commands into torque and speed commands for the inverter. The drivetrain controls a number of safety functions, including anti-lock brake system activation, hill-hold features, and programmable responsiveness for both acceleration and regeneration. We believe that multispeed gearboxes, paired with small high-performance motors, provide our customers compelling value, performance, and vehicle range.
High-voltage systems, controls, and telemetry gateways
To integrate the battery, drivetrain, charging, and other vehicle hardware, we developed a controls architecture for optimal system function, reliability, and safety. The core components of the control system are the battery management system, the charge controller that manages the interface between the battery and the charging system during charging, the telematics unit that provides wireless connectivity and supports vehicle monitoring and analytics, the drivetrain controller that interfaces with the motor and inverter, the vehicle controller that manages all base vehicle systems, including the high voltage and thermal systems, and the body controller that manages customer configurable functions such as HVAC, doors, lighting, and vehicle ride height.
Developed expressly for heavy duty and high-occupancy vehicle applications, our battery management system (“BMS”) and battery monitoring board (“BMB”) hardware, software, and patented control algorithms are designed to ensure safe and reliable operation in all commercial vehicle applications. The BMS is deployed on an automotive grade controller within the battery pack responsible for actively and safely managing a lithium ion battery pack. It controls the battery pack electrical contactors, monitors all relevant parameters, determines real-time state and limits designed to ensure safe and reliable operation, and communicates with the vehicle. Moreover, the BMS performs electrical safety functions such as isolation monitoring and high voltage interlock control. These functions are critical to performance and safety. Additional functions performed include measuring cell operating parameters such as voltage, temperature, and relative humidity and performing dissipative cell balancing.
These units and other devices, such as dashboard displays and other onboard electronics, are interconnected with industry standard Controller Area Network (“CAN Bus”) vehicle networking. Our controls team uses model-based control architecture to create software for each of these units and ensure proper validation through automated software testing. At the system level, we use these models in conjunction with industry-standard Hardware-In the-Loop and Software-In the-Loop test set-ups, which allow for full vehicle simulation and development.
ZX5 electric transit bus
The Proterra electric transit bus is our flagship product and the only finished vehicle we manufacture ourselves as an OEM. In 2014, we launched our first 40-foot electric low-floor transit bus seating up to 40 people, followed one year later by a 35-foot version seating up to 29 people. We focus on 35-foot and 40-foot buses because these buses represent more than three-quarters of the market according to the Federal Transit Authority’s National Transit Database. Currently offered with battery sizes up to 492 kWh on the 35-foot and base 40-foot, and up to 738 kWh on the ZX5 Max variant, our buses can provide a range of up to 340 miles on a single charge. With the batteries mounted in ballistic-grade enclosures below the floor of the vehicle between the axles, the bus has been designed to optimize mass distribution and safety. Enabled by our battery and electric drive train technology and a body made of light-weight composite materials, our purpose-built electric transit bus also offers compelling acceleration, gradeability, and energy efficiency. Along with zero tailpipe emissions and low
maintenance costs, the Proterra Electric Transit Bus offers a compelling value proposition to transit agencies seeking to electrify their fleets.
While other manufacturers use a modified steel body and frame that was originally designed for an internal combustion engine, we have partnered with a supplier, TPI Composites, Inc, to architect a lighter weight bus body with advanced materials specifically designed for an electric powertrain. Our composite bus body houses the battery packs below the floor of the vehicle, between the axles, to achieve a low center of gravity and ride comfort and safety. Utilizing carbon fiber and fiberglass, our design approach optimizes mass, stiffness, and durability. Our bus body has been tested on a four-post shaker table to a simulated 750,000 miles and 18 years of useful life, and has also undergone 125,000 effective miles at the Bus Research and Testing Center’s test track in Altoona, Pennsylvania which executes federally mandated transit vehicle durability testing.
The ZX5 bus can be charged by either a standard J1772 CCS charge port for in-depot charging, or a J3105 standard-compliant overhead pantograph charger, offering an estimated charge time of three hours. The latter can be deployed in-depot or used as an on-route charger for charge replenishment.
Our electric transit bus can also offer significant total cost of ownership savings as compared to the equivalent diesel- and natural gas-powered buses. Our electric transit bus uses approximately 75% less energy per mile than the average legacy diesel bus. In a typical transit operation, the total cost of ownership of our bus is lower than diesel, diesel-hybrid, and compressed natural gas-powered vehicles. Our electric transit bus combines a competitive upfront price with low operations and maintenance costs, which we estimate results in a lower total cost of ownership over the lifetime of the vehicle.
Proterra Transit electric buses can also be acquired with a battery lease through our battery leasing program. We offered this program in 2021 through a partnership with Mitsui, whose contract with us ended in March 2022. We are currently offering this program directly. This program enables the customer to pay for the price of the battery over time rather than upfront with the price of the bus. Given the operational savings our buses typically offer in both fuel and maintenance costs, we seek to structure the battery lease payments so they are covered by the operating cost savings.
Fleet-scale charging solutions
Fleet charging requires a complex balance of multiple stakeholder groups, fleet logistics, battery operational requirements, variable charging times and power, and electric utility engagement, which together present more challenges than passenger vehicle charging. Successful charging infrastructure implementation is critical to scaling the deployment of commercial electric vehicles. We have designed our charging solutions with a focus on high power, scalability, bi-directional power capability, autonomous charge docking, and charge management. We believe our software algorithms and planning solutions can enable as much as 50% fewer chargers, while optimizing both charging time and energy costs.
We currently offer five charger capacities for small fleet solutions: 60 kW, 90 kW, 120 kW, 150 kW, and 180 kW. We also offer a Megawatt class of charger for large fleet solutions. Our charger architecture is designed for commercial fleet applications and allows for the larger charging hardware cabinet to be placed up to 500 feet away from the charger dispensers. This architecture provides commercial fleets with more siting flexibility in depots with limited space. The dispensers can be ground-, wall-, or overhead structure-mounted to meet a customer’s specific requirements. Charging systems include a wireless data connection to our Valence software platform that allows for over-the-air software updates.
Valence software platform
The Proterra Valence (formerly called APEX) connected vehicle intelligence system is a cloud-based data platform that can provide customers performance information about their fleets, and is designed to provide management of vehicle and charging operations to reduce operating costs.
Our hardware and software connectivity platform is designed for compatibility with each vehicle and charging system that we deliver. Each gateway on a vehicle or charging system automatically connects securely with our cloud-based platform. Applications that run on this platform are accessible to registered users through a role-
based, access-controlled web portal. Our data exploration tools offer users current and historical metrics, insights, and reports. Metrics include odometer readings and mileages, battery state-of-charge, energy usage by subsystem, overall energy efficiency, route geolocation, and environmental impact. Charging voltages, power, energy delivered, and session start and stop times are also available. Real-time fault and status alert capabilities provide user notifications through email and text message. The telematics platform also provides charge management capability enabling optimization of power levels and energy costs based on bus arrival and departure schedules. The telematics platform can enable over-the-air updates, and over time we expect to expand its functionality to include further charge management capabilities which is expected to enable customers to minimize demand charges and further reduce energy costs. The Valence platform is designed to be flexible and can also be configured for use with other commercial electric vehicles.
Our Technology
Our technology platform supports our broad portfolio of products and services across the electrification ecosystem designed to overcome the most significant obstacles to commercial vehicle electrification. The primary features of our electric vehicle technology platform, designed to meet the unique requirements of commercial fleet electrification and differentiate it from the competition, include:
•Integrated technology solutions spanning the electrification ecosystem. Our proprietary commercial electric vehicle platform is centered on our Proterra Powered battery and electric drivetrain technology, is complemented by our Proterra Energy fleet-scale, high-power charging infrastructure solutions, and enhanced by our Valence fleet and energy management software-as-a-service platform, which is designed to enable customers to manage their vehicles and charging operations in real-time, reducing the total cost of ownership. Proterra Transit offers real-world validation, testing, and a positive feedback loop for our technology platform.
•Modular and flexible battery platform. We offer a modular battery platform available in different form factors, which can be produced on the same manufacturing line, to satisfy the specific needs of our customers and the design constraints of their vehicles. Commercial vehicles are not homogenous and span a wide range of weight classes (from Class 3 over 10,000 pounds to Class 8 over 33,000 pounds), chassis sizes, and frame rail lengths. We believe offering compatibility with as many different vehicle segments as possible without requiring equipment retooling or manufacturing customization is key to achieving higher market penetration. Enabled by the simplicity of design and integrated architecture of our battery modules, our battery packs are available in two widths and heights to accommodate different frame rails, various lengths ranging from 3-feet to 9-feet, and four different voltages which can be strung together in up to 16 parallel strings, with voltages as high as 1,200V. The modularity and manufacturability of our batteries enable us to provide solutions for a wide variety of commercial vehicle sizes and segments, ranging from as low as 35 kWh systems for commercial vans and shuttles up to 1 megawatt-hour (“MWh”) or more for long haul trucks and heavy-duty equipment.
•Highly efficient design enabling exceptional energy density and range. Our battery systems are structurally designed to optimize energy density, safety, and cost. We achieve this through a highly efficient design in which the cooling mechanisms, module structure, and pack structure are all the same element, reducing space, weight and cost. The high energy density of our battery systems increases vehicle efficiency, extends range and allows higher occupant or cargo capacity. Our focus on efficiency extends to our drivetrains, which we have designed to optimize torque and efficiency through the use of multi-speed transmissions to meet the demands of the most rigorous and diverse routes for commercial vehicles. As a result, relative to diesel’s low fuel efficiency of less than 5 miles per gallon, our electric vehicles can exceed 20 miles per gallon equivalent, generating significant cost savings. By implementing these efficient designs, maintenance costs can also be materially reduced given fewer moving parts, no need for oil changes, and less frequent brake replacements due to regenerative braking systems.
•Designed and certified for safety. Safety is a top priority in our battery design. In addition to offering higher energy density than typical electric passenger vehicle batteries, our commercial-grade batteries offer a high degree of safety and durability due in large part to two core design attributes: cooling and structural rigidity. Through the use of both active cooling and passive propagation resistance in module and pack construction, we have designed our batteries to achieve a lifespan required for commercial
vehicle use while operating under daily charge/discharge cycles and to maintain safe and reliable operation. Our battery systems incorporate hundreds of sensors that continuously monitor the active and passive safety systems with multiple layers of redundancy. In addition, we designed our battery packs to be structurally robust, providing protection against strenuous duty cycles and high impact incidents. Our battery systems have been certified by Underwriter Laboratories to be compliant to ISO 26262, which represents today’s state-of-the-art for functional safety for road vehicles. We have also received ECE-R100 certification required to deliver certain product to our European customers. These certifications can provide us a competitive advantage, especially in markets where the certification is a prerequisite to sell electric vehicles and with vehicle OEMs that have their own standards for component safety.

While we obtain some components from multiple sources, in some cases we also purchase significant components used in our products from a single source that we have validated. For our battery cells, we have two qualified suppliers for supply chain resiliency but have only used one of these suppliers, LG Energy Solution, for our current battery system to date. We also operate a cell testing lab where we regularly empirically evaluate the performance and reliability of new cells and cell chemistries from a wide range of global cell manufacturers.
We obtain systems, components, raw materials, parts, manufacturing equipment, and other supplies from suppliers that we believe to be reputable and reliable. We have established and follow internal quality control processes to source suppliers, considering engineering validation, quality, cost, delivery, and lead-time. We have a quality management team that is responsible for managing and ensuring that supplied components meet quality standards. Our quality standards are guided by industry standards, including Automotive Industry Action Group, Advanced Product Quality Planning, and Production Part Approval Process procedures, which were developed by the U.S. auto industry.
Our electric transit buses use purchased parts that are primarily sourced from American suppliers. We developed our supply chain to comply with the Federal Transit Administration’s (“FTA”) Buy America requirements and the Federal Aviation Administration’s (“FAA”) Buy American requirements, which govern transit bus procurements that are paid for, in part, with federal funds by transit agencies and airports, respectively. For certain Canadian customers, we source select vehicle content from Canadian suppliers in order to comply with Canadian Content requirements.
Manufacturing
We have battery manufacturing facilities in City of Industry and Burlingame, California, and Powered 1 battery factory at Greer, South Carolina, which started production in January 2023. We manufacture electric transit buses at each of our facilities in City of Industry and Greenville. In January 2023, we announced a plan designed to improve operational efficiency, including the planned closure of our City of Industry facility. We will move manufacturing from our City of Industry facility to our existing facilities in Greenville. Transit bus production in the City of Industry facility is expected to end in the first quarter of 2023, and battery production at the City of Industry
facility is expected to end by the end of the third quarter of 2023. We plan to vacate the City of Industry facility by the end of 2023.
We strive to instill a manufacturing culture of continuous improvement and leverage best practices in quality control and worker safety across our facilities. We are ISO 14001 certified in our Burlingame, City of Industry, and Greenville facilities.

Warranty
We offer warranties for our battery systems, electric transit buses, including their major subsystems, and charging systems.
Our battery system warranty is dependent on the vehicle and its usage. We offer 6-year standard warranty and 12-year extended warranty on the battery for materials and workmanship, and an energy capacity warranty that depends on vehicle capacity and expected usage. We typically offer two to five-year warranties on other ancillary components of our powertrain system. Our standard warranty on battery systems reserves the right to replace components with different items of equal or better performance to keep pace with improvements in battery technology development.
Our electric transit bus warranty is comprised of a one-year complete bus warranty, a 12-year warranty on our composite bus body, and warranties on other components generally ranging from one to three years. Transit agencies will often request additional coverage as part of the initial capital purchase, in part to minimize their operational costs. We price these extended warranties into our contract bids.
Under the fleet defect provisions included in some electric transit bus purchase contracts, we are required to proactively prevent re-occurrences of a defect in the entire fleet of electric transit buses delivered under a contract if the same defect occurs in more than a specified percentage of the fleet within the base warranty period (or sometimes base warranty period plus one year) following delivery of the electric transit bus.
We offer a standard two-year warranty on our charging hardware. Warranties for installed third party hardware can extend up to five years. When we have offered extended warranty coverage beyond the suppliers’ warranty, we have priced these extended warranties into our contract bid.
Government regulations, funding, and other programs
Regulations and programs
Battery safety and testing
Our battery system complies with all requirements of the SAE J2929 Safety Standard for Electric and Hybrid Vehicle Propulsion Battery Systems Utilizing Lithium-based Rechargeable Cells. In addition, we test our battery systems according to industry standards, including from the SAE, the Economic Commission for Europe (“ECE”), and Underwriters Laboratories (“UL”), as well as our own internal standards, for conditions, including mechanical abuse, thermal cycling, humidity, water immersion, corrosion, and short circuit events. We have also completed applicable transportation tests for our battery packs, demonstrating our compliance with applicable regulations that govern the transport of lithium-ion batteries.
Certain materials in our battery packs contain trace amounts of hazardous chemicals, whose use, storage, and disposal are regulated under federal and state law. In addition, we are subject to international regulatory and safety requirements, including the European Union’s directives related to hazardous substances such as Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”) and the Restriction of Hazardous Substances (“RoHS”). Most of our battery systems are recyclable, which enables us to develop battery recycling programs with third parties to recycle our battery packs at the end of their useful life.
Model bus testing program
The FTA mandates that new transit bus models, and subsequent material changes to those models, be physically tested to meet certain performance standards in order to be eligible to receive federal transit funding. Altoona Testing is designed to promote production of better transit vehicles and components, and to ensure that transit customers purchase vehicles that are able to withstand the rigors of transit service. Altoona Testing, typically a required pre-condition for customer acceptances, is available to vendors on a first-come, first-served basis and subject to a waiting list. To date, our 40-foot and 35-foot buses have completed Altoona Testing, but as material changes are made to our bus platform, we must undergo new rounds of testing.
The vehicles we sell in Canada are subject to different safety testing regulations and may require redesign or additional testing.
Zero Emission Certifications
In addition, we are subject to the Environmental Protection Agency (“EPA”) and California Air Resources Board’s (“CARB”) annual certification greenhouse gas emissions requirements related to our transit vehicle and powertrain. The CARB certification is required to participate in California’s Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (“HVIP”), which offers vouchers to our customers to reduce the purchase price of zero-emission vehicles.
Motor Vehicle Safety Standards
The United States NHTSA mandates that vehicles, including transit buses, meet all the Federal Motor Vehicle Safety Standards (“FMVSS”) testing requirements issued by the agency. We self-certify that our electric transit buses comply with applicable FMVSS as of the date of vehicle production. Our electric transit buses must also conform to state and local requirements which vary by jurisdiction. Transit buses sold in Canada must also meet Canada Motor Vehicle Safety Standards (“CMVSS”). Transport Canada monitors FMVSS for applicability to Canada to further align with U.S. regulations, adopting or modifying an FMVSS to address unique usage and environmental conditions in the Canadian market.
Government funding opportunities
Federal funding programs for zero-emission commercial vehicles
On November 15, 2021, President Biden signed the Infrastructure and Investment Jobs Act, also referred to as the “Bipartisan Infrastructure Law”, into law. The Bipartisan Infrastructure Law created a number of new funding opportunities for Proterra Powered & Energy customers. The EPA will receive $5 billion over 5 years for the Clean School Bus program, which provides $500 million per year for zero emission school buses, as well an additional $500 million per year for low or zero emission school buses. The EPA also continues to administer the Diesel Emission Reduction Act grant program, which provides funding for transit, school bus, drayage, refuse, and other vehicle types that are low or zero emission. Finally, the Bipartisan Infrastructure Law also provides funding through discretionary and formula programs to various departments at the US Department of Transportation and, can potentially fund opportunities to electrify commercial vehicles at airports, ports, and other locations.
In August 2022, the Inflation Reduction Act was signed into law, adding additional funding and tax credit programs for commercial vehicles, including a commercial clean vehicle credit, a number of which are expected to become available to recipients in 2023.
Federal formula and competitive funding programs for transit customers
Our transit customers are generally transit authorities who depend on federal government funding and programs authorized for public transportation under Title 49, Chapter 53 of the United States Code, and administered by the FTA, as well as other state funding programs. Federal and state funding has accelerated the adoption of electric vehicles in this market. Our principal customers are eligible for government funding, including, in particular, programs authorized under the Fixing America’s Surface Transportation (FAST) Act, to accelerate their investments in electric transit fleets. Passed in December 2015, the FAST Act allocated over $305 billion for highway, transit, and vehicle safety programs for a five-year period ending September 30, 2020. The FAST Act was subsequently extended and then reauthorized by the Bipartisan Infrastructure Law through the federal government’s fiscal year 2026.
The Bipartisan Infrastructure Law provides approximately $567 billion to discretionary and formula programs under the U.S. Department of Transportation’s (“USDOT”) jurisdiction, including approximately $39 billion of funding to transit, which represents an increase of 43% compared to amounts authorized under the FAST Act. Among other programs, the Bipartisan Infrastructure Law authorized a supplemental appropriation of $5.25 billion over five years for the Low or No Emission Program. Although 25% of this funding is reserved for low-emission buses only, it will provide over $850 million per year for funding zero-emission transit buses and infrastructure, a 14-fold increase over the authorized amounts in the FAST Act. The Bipartisan Infrastructure Law also funds the Buses and Bus Facilities competitive program at $376 million in 2022 to $412 million in 2026.
State funding programs
Certain states offer vouchers and other incentives for clean energy vehicles. California offers HVIP, which provides a point-of-sale discount to organizations that purchase fleets of hybrid and electric trucks and buses. The HVIP vouchers are targeted to offset about 80% of the incremental cost of hybrid and electric trucks and buses. In 2021, the state of California passed a historic zero-emission vehicle and infrastructure funding package for fiscal year 2021-2022, which includes $269.5 million for the HVIP program as well as $130 million set aside for HVIP for school buses, $70 million set aside for transit vehicles, and $75 million for HVIP for drayage trucks. California also offers vouchers for clean off-road equipment (“CORE”), such as cargo handling equipment. California’s FY2021-2022 budget includes $194.95 million for CORE vouchers. California’s zero-emission vehicle and infrastructure funding package for fiscal year 2021-2022 also provided for $873 million in funding for clean heavy-duty vehicles and off-road equipment in fiscal year 2021-2022 (to be implemented by the California Air Resources Board) and $391 million in funding for medium- and heavy-duty ZEV infrastructure in fiscal year 2021-2022 (to be implemented by the California Energy Commission).
New York offers the Truck Voucher Incentive Program, which funds low- and zero-emission transit buses and other vehicles. Other states offer similar programs that provide point-of-sale discounts to purchasers of electric vehicles, which help our customers offset the costs of purchasing our transit vehicles. To be eligible vehicles, our
electric transit buses must meet certification requirements for electric vehicles from the EPA and, where applicable, California Air Resources Board. Additionally, there are other state programs that help fund electric bus purchases. For example, states are allocating portions of settlement funds from the approximately $15 billion Volkswagen Emissions Settlement Program to investments in zero-emission transit buses, and the state of California has allocated about 10% of its annual Cap-and-Trade funds to California’s Transit and Intercity Rail Capital Program.
State emissions credits
Public transit agencies and other customers may be eligible for emission reduction credits through state programs.
The California Low Carbon Fuel Standard (“LCFS”) enables transit agencies using electricity as a source of fuel to opt into the LCFS program and earn credits that can be monetized. While the value of these credits fluctuates, the credits may help to offset up to half of the fuel costs for our transit customers.
Intellectual property
The protection of our technology and intellectual property is an important aspect of our business. We rely upon a combination of patents, trademarks, trade secrets, copyrights, confidentiality procedures, contractual commitments, and other legal rights to establish and protect our intellectual property. We generally enter into confidentiality agreements and invention or work product assignment agreements with our employees and consultants to control access to, and clarify ownership of, our proprietary information.
As of December 31, 2022, we held 77 issued U.S. patents and had 25 U.S. patent applications pending. We also held 31 issued patents and 30 patent applications pending in a foreign jurisdiction. Our U.S. issued patents expire between 2029 and 2040. As of December 31, 2022, we held 8 registered trademarks in the United States, including the Proterra mark, and also held 14 registered trademarks in foreign jurisdictions. We continually review our development efforts to assess the existence and patentability of new intellectual property. We intend to continue to file additional patent applications with respect to our technology.
Human Capital Management
We believe that our talented workforce and our mission driven company culture are competitive advantages and we have taken steps to strengthen our culture and focus on workforce development and engagement as we have grown. As of December 31, 2022, we employed 1,247 full-time equivalent employees. In January 2023, we announced a reduction of approximately 25% of our workforce across multiple locations and closure of our City of Industry facility where we manufacture transit buses and battery systems. We continue to hire new employees based on business needs. Our production employees in City of Industry are represented by the United Steel Paper & Forestry, Rubber, Manufacturing, Energy, Allied & Industrial Service Workers International Union AFL-CIO, CLC and we have a collective bargaining agreement with the union that will terminate with the wind down of the City of Industry facility. We do not have collective bargaining agreements in any of our other facilities.
In 2022, we focused on our culture by engaging our employees and leadership through surveys, focus group meetings, cross functional working sessions, and establishing an employee task force to work with external consultants to refine and communicate our shared values of innovation, adaptability, continuous improvement, teamwork & collaboration, inclusion, kindness, and sustainability. We also hired our first Chief People Officer in October 2022.
Health and Safety
We are a manufacturer and a technology company. We are committed to providing safe and healthful working conditions for all of our employees across all of our development, testing, and manufacturing environments, and at all of our locations and customer’s job sites. Safety is routinely addressed at our Board, leadership, staff and production meetings throughout the company. We strive to ensure safe, responsible and sustainable operations across all aspects of our business.
Compensation and Benefits
Our competitive compensation and benefit programs are designed to attract and retain talented and diverse employees across our manufacturing, technology, leadership and support functions. In addition to competitive wages and salaries, we offer comprehensive medical, dental and vision plans, an employee assistance program, flexible spending programs, family and other leave programs, commuter benefits, a Company matched 401(k) Plan, and an employee stock purchase plan and opportunities to be awarded equity grants under our equity incentive plan.
Inclusion and Diversity
Proterra is committed to hiring inclusively, fostering an inclusive culture, and ensuring equitable pay for employees. We continue to focus on increasing diverse representation at every level of the Company. Our leadership team is measured by the Board of Directors on our progress against diversity, equity and inclusion goals.
Workplace Policies
We ask our employees to read and acknowledge our Code of Business Conduct and Ethics each year. Proterra has a zero tolerance policy for discrimination or harassment. We are committed to providing a workplace free of harassment or discrimination based on gender, race, color, religion, age, citizenship, sexual orientation, gender identity, gender expression, marital status, pregnancy, national origin, ancestry, physical or mental disability or condition, and other legally protected status.

ITEM 1A. RISK FACTORS
Item 1A. Risk Factors
Investing in our securities involves risks. You should consider carefully the risks and uncertainties described below, together with all of the other information in this Annual Report, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes, before deciding whether to purchase any of our securities. Our business, results of operations, financial condition, and prospects could also be harmed by risks and uncertainties that are not presently known to us or that we currently believe are not material. If any of these risks actually occur, our business, results of operations, financial condition, and prospects could be materially and adversely affected. Unless otherwise indicated, references in these risk factors to our business being harmed will include harm to our business, reputation, brand, financial condition, results of operations, and prospects. In such event, the market price of our securities could decline, and you could lose all or part of your investment.
Risks Related to Our Financial Condition
Our independent registered public accounting firm's audit report includes an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern, indicating the possibility we may not be able to operate in the future.
Under ASC Subtopic 205-40, Presentation of Financial Statements-Going Concern (“ASC 205-40”), we have the responsibility to evaluate whether conditions and/or events raise substantial doubt about our ability to meet our future financial obligations as they become due within one year of the financial statements included elsewhere in this Annual Report on Form 10-K being issued.
Pursuant to the terms of the purchase agreement governing the Convertible Notes, we are required to maintain Liquidity (as defined therein) as of the last day of each quarter of not less than the greater of (a) $75.0 million and (b) an amount equal to the product of multiplying (i) the amount of Cash Burn (as defined therein) from operations for the three-month period ending on the end of such month by (ii) four (the “Minimum Liquidity Covenant”).
As of December 31, 2022, we did not have Liquidity in an amount equal to clause (b) above as of such date. As a result, we obtained a waiver of the Minimum Liquidity Covenant for the quarter ended December 31, 2022. Without such waiver, we would have been in default of the Convertible Notes, which would have resulted in a cross-default under the Senior Credit Facility. However, we have not obtained a waiver of the Minimum Liquidity Covenant for any future periods, and, as a result of anticipated operating cash outflows from operation, capital investment at our Powered 1 battery factory, and incremental cash payments for the workforce restructuring we announced in January 2023, we may not satisfy the Minimum Liquidity Covenant as of March 31, 2023 for the quarter ended March 31, 2023.
In addition, the audit report included elsewhere in this Annual Report on Form 10-K contains a going concern qualification, and our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern is an event of default under both the Convertible Notes and the Senior Credit Facility. We have obtained a prospective limited waiver under the Convertible Notes, which will expire on March 31, 2023, with respect to our obligations under the Convertible Notes to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern in connection with this Annual Report on Form 10-K, and a cross-default under the Convertible Notes with respect to the Senior Secured Credit Facility, resulting from the substantially similar covenant thereunder. If we are unable to obtain a further waiver under the Convertible Notes beyond March 31, 2023, then there would be an event of default under the Convertible Notes for failure to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) in this Annual Report on Form 10-K, which would be a cross-default under the Senior Credit Facility, unless waived. An event of default under the Convertible Notes would permit the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable.
In addition, we have not obtained a waiver with respect to the corresponding covenant under the Senior Credit Facility as of the date hereof and we are therefore in default of such covenant as of the issuance of the financial statements and related audit report included elsewhere in this Annual Report on Form 10-K. Unless waived, the default under the Senior Credit Facility resulting from the issuance of these financial statements and related audit report containing a going concern qualification (and potential cross-default under the Convertible Notes if we are unable to obtain a waiver thereunder beyond March 31, 2023), permits (and would permit) the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable.
If we are unable to comply with or obtain a waiver for the Minimum Liquidity Covenant, if applicable, for the quarter ended March 31, 2023 or a future period (and/or if we are unable to obtain a waiver under the Convertible Notes beyond March 31, 2023 with respect to our obligations under the Convertible Notes to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern in connection with this Annual Report on Form 10-K and cross-default under the Convertible Notes with respect to the Senior Secured Credit Facility), there would be an unwaived event of default under the Convertible Notes and a cross-default under the Senior Credit Facility on March 31, 2023 or such future period, which would permit (i) the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable and (ii) the Lenders under the Senior Credit Facility to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable and to terminate all commitments to extend credit under the Senior Credit Facility. If such indebtedness were to become immediately due and payable in the event of such a default this would have an immediate adverse effect on our ability to meet our working capital needs and our business and operating results.
The current and potential events of default under the Convertible Notes and the Senior Credit Facility when coupled with the following conditions: our available cash resources, recurring losses and cash outflows from operations, an expectation of continuing operating losses and cash outflows from operations for the foreseeable
future, and the need to raise additional capital to finance our future operations, causes substantial doubt about our ability to continue as a going concern to exist.
There is no assurance that we will be able to obtain any future waivers under the Convertible Notes or the Senior Credit Facility or other resolution with the holders of the Convertible Notes and the lenders under the Senior Credit Facility on a timely basis, on favorable terms or at all. We would need to take further action to raise additional funds in the capital markets or otherwise to fund our obligations under the Convertible Notes in addition to our other obligations over the one-year period from the issuance of the financial statements included elsewhere in this Annual Report on Form 10-K, and we would not be able to draw upon the Senior Credit Facility. If we do not have sufficient funds or we are unable to arrange for additional financing to repay outstanding debt, the lenders under the Senior Credit Facility and holders of the Convertible Notes could seek to enforce their security interests in the collateral securing the indebtedness under the Senior Credit Facility and the Convertible Notes, which are secured substantially by all our assets including intellectual property and other restricted property.
We expect to seek additional funds through potential securities financings, debt financings or other capital sources or strategic transactions. In addition, we may seek to obtain a waiver or amendment of our existing debt agreements. However, we may not be successful in securing additional financing on acceptable terms or at all, or in obtaining a waiver or amendment to our existing debt agreements. Furthermore, high volatility and uncertainty in the capital markets resulting from the COVID-19 pandemic and macroeconomic conditions, including rising inflation rates and interest rates, and recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, has had, and could continue to have, and a negative impact on the credit and financial markets and on the price of our common stock and could adversely impact our ability to raise additional funds. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors, or other financing sources may be unwilling to provide funding to us on commercially reasonable terms, if at all. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate some of our business activities, including related operating expenses, and our suppliers could impose more onerous terms on us, such as requiring cash payments prior to parts delivery, which would adversely affect our business prospects and our ability to continue our operations and would have a negative impact on our financial condition and ability to pursue our business strategies, and we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and/or seek protection under Chapters 7 or 11 of the United States Bankruptcy Code. This could potentially cause us to cease operations and result in a complete or partial loss of your investment in our common stock.
Senior Credit Facility and Convertible Notes contain covenants that have and may in the future restrict our business and financing activities. We are in covenant default under the Senior Credit Facility and we have obtained waivers of certain covenants contained in the Convertible Notes. If we are not able to obtain further waivers with respect to, or comply with our covenants under the Senior Credit Facility and Convertible Notes, we would continue to be in default of the Senior Credit Facility or may be in default under one or both of the Senior Credit Facility or Convertible Notes which may have an immediate adverse effect on our business.
Each of Senior Credit Facility and Convertible Notes is secured by substantially all our assets, including our intellectual property and other restricted property. Subject to certain exceptions, the Senior Credit Facility and Convertible Notes also restrict our ability to, among other things:
•dispose of or sell our assets;
•make material changes in our business or management, or accounting and reporting practices;
•acquire, consolidate, or merge with other entities;
•incur additional indebtedness;
•create liens on our assets;
•pay dividends;
•make investments;
•enter transactions with affiliates; and
•pre-pay other indebtedness.
The covenants in the Senior Credit Facility, Convertible Notes, and any future financing agreements that we may enter, may restrict our ability to finance our operations, engage in, expand or otherwise pursue our business activities and strategies. See the Risk Factor entitled - Our independent registered public accounting firm's audit report includes an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern, indicating the possibility we may not be able to operate in the future - for risks related to our events of default, cross-defaults under the debt instruments, and related waivers, as applicable, concerning maintaining Liquidity (as defined in the Convertible Notes) and our failure to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) in our Annual Report on Form 10-K for the period ending December 31, 2022 under the Senior Credit Facility and the Convertible Notes. Further, if we fail to comply with our debt covenants in the future, there is no assurance that we will be able to obtain any future waivers under the Convertible Notes or the Senior Credit Facility.
If the Convertible Notes were to become immediately due and payable because of such events of default, we may not have sufficient cash available to repay our obligations under the Convertible Notes and meet the working capital needs of our business, which would have an immediate adverse effect on our business and operating results. We would need to take further action to raise additional funds in the capital markets or otherwise to service our obligations under the Convertible Notes in addition to our other obligations over the period, and we would not be able to draw upon the Senior Credit Facility. If we do not have sufficient funds or we are unable to arrange for additional financing to repay outstanding debt, holders of the Convertible Notes could seek to enforce their security interests in the collateral securing the Convertible Notes, which are secured substantially by all our assets including intellectual property and other restricted property, and we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and/or seek protection under Chapters 7 or 11 of the United States Bankruptcy Code, and it is likely that investors will lose all or a part of their investment.
We will require additional capital to support business growth, and such capital might not be available on terms acceptable to us, if at all.
We expect to seek additional funds through potential securities financings, debt financings or other capital sources or strategic transactions. We intend to continue to make investments to support our business growth and will require additional funds to respond to business challenges, including the need to improve our operating infrastructure or acquire complementary businesses and technologies. Accordingly, we will need to engage in the issuance of public or private equity, equity-linked, debt securities or other financing or strategic transaction to secure additional funds. We may not be able to obtain additional financing on a timely basis or on terms favorable to us, if at all. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing that we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, including the ability to pay dividends. This may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential strategic transactions.
There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur, including as a result of recent bank failures. A severe or prolonged economic downturn could result in a variety of risks to our business, including weakened demand for our products and harm our ability to raise additional capital when needed on acceptable terms, if at all. If the equity and credit markets continue to deteriorate, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could impair our ability to achieve our growth strategy, could harm our financial performance and stock price and could require us to delay or abandon our business plans. We cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our access to capital. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and respond to business challenges could be significantly impaired, and our business, prospects, financial condition, and operating results could be adversely affected.See the Risk Factor entitled - Our independent registered public accounting firm's audit report includes an explanatory paragraph expressing
substantial doubt about our ability to continue as a going concern, indicating the possibility we may not be able to operate in the future, for additional risks related to our ability to raise additional capital.
If our estimates or judgments relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our operating results could be adversely affected.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments, and assumptions that affect the amounts reported in our financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets, liabilities, and equity as of the date of the financial statements, and the amount of revenue and expenses, during the periods presented, that are not readily apparent from other sources. Significant assumptions and estimates used in preparing our financial statements include those related to determination of revenue recognition, stock-based compensation, inventory, and warranties. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of industry or financial analysts and investors, resulting in a decline in the trading price of our common stock.
Additionally, we regularly monitor our compliance with applicable financial reporting standards and review new pronouncements and drafts thereof that are relevant to us. As a result of new standards, changes to existing standards, and changes in interpretation, we might be required to change our accounting policies, alter our operational policies, or implement new or enhance existing systems so that they reflect new or amended financial reporting standards, or we may be required to restate our published financial statements. Changes to existing standards or changes in their interpretation may have an adverse effect on our reputation, business, financial position, and profit, or cause an adverse deviation from our revenue and operating profit target, which may negatively impact our financial results.
We have identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the future. If we fail to remediate these material weaknesses or otherwise fail to establish and maintain effective control over financial reporting, it may adversely affect our ability to accurately and timely report our financial results in the future, and may adversely affect investor confidence, our reputation, our ability to raise additional capital, and our business operations and financial condition.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
Management, with the participation of the principal executive officer and principal financial officer, under the oversight of our board of directors, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2022, using the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was not effective as of December 31, 2022, because of the material weaknesses in internal control over financial reporting, described below.
We did not have a sufficient number of trained resources with assigned responsibility and accountability for the design, operation and documentation of internal control over financial reporting.
As a result:
•We did not have an effective risk assessment process that defined clear financial reporting objectives and evaluated risks at a sufficient level of detail to identify all relevant risks of material misstatement across the entity.
•We did not have an effective information and communication process that identified and assessed the source of and controls necessary to ensure the reliability of information used in financial reporting and
that communicates relevant information about roles and responsibilities for internal control over financial reporting.
•We did not have effective monitoring activities to assess the operation of internal control over financial reporting, including the continued appropriateness of control design and level of documentation maintained to support control effectiveness.
As a consequence, we did not effectively design, implement, or operate process-level control activities for substantially all of our financial reporting processes.
Our management, with the oversight of the audit committee of our board of directors, is in the process of designing and implementing a remediation plan and is taking steps to remediate the material weaknesses. The material weaknesses will not be considered remediated until such time as management designs and implements effective controls that operate for a sufficient period of time and concludes, through testing, that these controls are effective. Furthermore, we cannot ensure that the measures we have taken to date, and actions we may take in the future, will be sufficient to remediate in a timely manner or at all the control deficiencies that led to our material weakness in our internal controls over financial reporting or that they will prevent or avoid potential future material weaknesses due to a failure to implement and maintain adequate internal control over financial reporting or circumvention of these controls. In addition, even if we are successful in strengthening our controls and procedures, in the future these controls and procedures may not be adequate to prevent or identify irregularities or errors or to facilitate the fair presentation of our financial statements.
We will need to continue to dedicate internal resources, engage outside consultants and maintain a detailed work plan to assess and document the adequacy of internal control over financial reporting, continue steps to remediate the material weakness and any future control deficiencies or material weaknesses, and improve control processes as appropriate, validate through testing that controls are functioning as documented and maintain a continuous reporting and improvement process for internal control over financial reporting. If we are not able to correct material weaknesses or deficiencies in internal controls in a timely manner or otherwise comply with the requirements of Section 404 in a timely manner, our ability to record, process, summarize and report financial information accurately and within applicable time periods may be adversely affected and we could be subject to sanctions or investigations by the SEC, the Nasdaq Stock Market or other regulatory authorities as well as shareholder litigation which would require additional financial and management resources and could adversely affect the market price of our common stock. Furthermore, if we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our common stock.
Any failure to remediate the material weaknesses or otherwise develop or maintain effective controls or any difficulties encountered in their implementation or improvement could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in material misstatements of our annual or interim financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to the listing requirements of the Nasdaq. For example, in connection with the identification of the material weakness described above, we were unable to file this Annual Report on Form 10-K by the deadline prescribed by the SEC and, as a result, we are currently not eligible to utilize a Form S-3 registration statement. Additionally, investors may lose confidence in our financial reporting and our stock price may decline as a result. In addition, perceptions of the Company among customers, suppliers, lenders, investors, securities analysts and others could also be adversely affected.
Risks Related to Our Business and Industry
Our limited history of selling battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies makes it difficult to evaluate our business and prospects and may increase the risks associated with your investment.
Although Legacy Proterra was incorporated in 2004, we only began delivering electric vehicles in 2010, and through December 31, 2022, had delivered over 1,000 electric transit buses. In 2022, 2021 and 2020, we
recognized $309.4 million, $242.9 million, and $196.9 million in total revenue, respectively. Since 2010, our product line has changed significantly, and our most recent transit bus model has only been in operation since 2020. Further, we started developing our battery technology in 2015 and did not begin battery pack production in any significant volume until 2017. We also have limited experience deploying our electric powertrain technology in vehicles other than electric transit buses. In 2018, we announced our software platform for connected vehicle intelligence, which we now refer to as our Valence (formerly called APEX) fleet and energy management software-as-a-service platform, which has only had beta customers until recently; we just relaunched the platform as Valence in 2022. Our energy services, which includes fleet planning, charging infrastructure and related energy management services, only began generating limited revenue in 2019. We began providing integrated charging solutions in 2019 and have only begun sourcing our new charging hardware from a new partner in 2020, with our first deliveries occurring in 2021.
As a result, we have a limited operating history upon which to evaluate our business and future prospects, which subjects us to a number of risks and uncertainties, including our ability to plan for and predict future growth. Our limited operating experience is particularly concentrated in our Proterra Transit line of business, and that limited experience may not prove to be relevant to Proterra Powered and Proterra Energy. As a result, the operating history of Proterra Transit may not prove to be predictive of the success of Proterra Powered and Proterra Energy.
Moreover, because of the limited deployment of our products and services to date and our focus on electric transit buses, defects or other problems with our products or industry-wide setbacks that impact the electric vehicle market may disproportionately impact our ability to attract additional customers or sell to existing customers, and harm our brand and reputation relative to larger, more established vehicle manufacturers that have a longer operating history and investments in more than one technology. We have encountered and expect to continue to encounter risks and difficulties experienced by growing companies in rapidly developing and changing industries, including challenges related to achieving market acceptance of our existing and future products and services, competing against companies with greater financial and technical resources, competing against entrenched incumbent competitors that have long-standing relationships with our prospective customers in the commercial vehicle market, including the public transit market and other transportation markets, recruiting and retaining qualified employees, and making use of our limited resources. We cannot ensure that we will be successful in addressing these and other challenges that we may face in the future, and our business may be adversely affected if we do not manage these risks appropriately. As a result, we may not attain sufficient revenue to achieve or maintain positive cash flow from operations or profitability in any given period, or at all.
We have a history of net losses, have experienced rapid growth and anticipate increasing our operating expenses in the future, and may not achieve or sustain positive gross margin or profitability in the future.
We incurred net losses of $238.0 million, $250.0 million, and $127.0 million in 2022, 2021, and 2020, respectively, and we expect to incur net losses for the foreseeable future. As of December 31, 2022, we had an accumulated deficit of $1.1 billion. We expect to make significant expenditures related to the development and expansion of our business, including: making new capital investments and continuing investments in our electric powertrain, including advancements in our battery technology and high voltage systems; hiring and retaining qualified employees; adding additional production lines or production shifts in our manufacturing facilities; building new manufacturing facilities; expanding our software offerings; expanding our business into new markets and geographies; research and development in new product and service categories; and in connection with legal, accounting, and other administrative expenses related to operating as a public company.
We have also experienced rapid growth in recent periods. For example, our number of employees has increased significantly over the last few years, from 492 full-time employees as of December 31, 2018 to 1,247 full-time employees as of December 31, 2022. On January 13, 2023, we approved a plan designed to improve operational efficiency, including reducing our workforce by approximately 25% and closing our City of Industry facility. We will move manufacturing from our City of Industry facility to our existing facilities in South Carolina. In transitioning manufacturing facilities, we may experience delays and disruptions in our manufacturing and production activities. We also expect to continue to hire new employees, particularly for our manufacturing facilities in South Carolina. Managing our growth has and will place significant demands on our management as well as on our administrative, operational, legal and financial resources. To manage our growth effectively, we must continue to improve and expand our infrastructure, including our information technology, financial, legal, compliance and administrative systems and controls. We must also continue to effectively and efficiently manage our employees, operations, finances, research and development, and capital investments.
All of these efforts may prove more expensive than we currently anticipate, and we may not succeed in increasing our revenue sufficiently, or at all, to offset these higher expenses. While our revenue has grown in recent periods, our operating expenses have also increased significantly. If our revenue declines or fails to grow at a rate faster than increases in our operating expenses, or we are unable to increase gross margin, whether through reducing the cost of production or increasing sales, we would not be able to achieve and maintain profitability in future periods. As a result, we may continue to generate losses. We cannot ensure that we will achieve profitability in the future or that, if we do become profitable, that we will be able to sustain profitability.
Our operating results have fluctuated and may fluctuate from quarter to quarter, which makes our future results difficult to predict.
Our quarterly operating results have fluctuated in the past and may fluctuate in the future. Our revenue recognition with respect to electric transit buses and charging systems depends on the timing of delivery and customer acceptance. Large order sizes may result in a significant number of electric transit buses or charging systems being accepted or rejected at one time, which could disproportionately impact revenue recognition in a given quarter. Revenue for battery systems and electrification and charging solutions is less dependent on customer acceptance but can be unpredictable based on our customers’ ability to cancel within lead times. Additionally, we have a limited operating history, which makes it difficult to forecast our future results and subjects us to several risks and uncertainties, including our ability to plan for and anticipate future growth. As a result, our past quarterly operating results may not be reliable indicators of future performance, particularly in our rapidly evolving market.
Our operating results in any given quarter can be influenced by numerous factors, many of which are unpredictable or are outside of our control, including:
•our ability to maintain and grow our customer base and to sell additional products to our existing customers;
•our ability to build a reputation as a manufacturer of quality battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses and to build trust and long-term relationships with customers;
•the effects of the ongoing COVID-19 pandemic, particularly with respect to funding for state and federal transit programs and reduced operating revenue from reduced passenger levels, and the effect on our suppliers;
•the amount of funding appropriated annually for state and federal transit programs and the amount and timing of government funding programs for electric vehicles;
•our ability to deliver our products as planned to meet our revenue goals and avoid liquidated damages within certain contracts, which may depend on factors such as supply shortages of components and component quality issues, customer configuration, manufacturing, or shipping delays, our ability to manage logistics, and to accurately forecast inventory and labor requirements;
•the mix of order size for transit bus orders, and variations in profit margins for each contract, which may affect our overall gross margin in any particular period;
•fluctuations in the cost and availability of raw materials, including as a result of tariffs and other trade restrictions;
•cancellations or modifications of awards or orders by our customers;
•our ability to design and produce safe, reliable, and quality products on an ongoing basis;
•levels of warranty claims or estimated costs of warranty claims and vehicle or equipment recalls;
•our ability to distinguish ourselves from competitors in our industry by developing and offering competitive products, effectively partner with manufacturers in adjacent markets and respond to competitive developments, including the introduction of new battery systems, electrification and charging solutions, fleet and energy management software or electric transit buses and pricing changes by our competitors;
•our ability to promote the adoption of electric vehicles over other fuel solutions such as diesel-hybrid, hybrid, or compressed natural gas vehicles or battery electric fuel cell vehicles;
•the success and timing of our strategic relationships to enter adjacent markets;
•pricing pressure as a result of competition or otherwise;
•our ability to implement cost reduction measures;
•buying patterns of customers, and the procurement schedules of our current and prospective customers in the public transit market, school bus market, and other commercial vehicle markets;
•current and evolving industry standards and government regulations that impact our business at the federal, state, and local level, particularly in the areas of product safety and rules of origin such as Buy America, Buy American, and provincial Canadian Content regulations, and competitive bidding regulations at the federal, state and local level for electric transit buses;
•the timing of testing by, and the ability of our buses to pass, the FTA’s federal bus testing program;
•delays or disruptions in our supply, manufacturing, or distribution chain, including insolvency, credit, or other difficulties confronting our key suppliers;
•our ability to effectively manage the length and complexity of our sales cycles;
•the mix of financing alternatives that we offer and our customers choose to utilize;
•our ability to continuously improve our product without obsoleting inventory or production tooling;
•litigation, adverse judgments, settlements, or other litigation-related costs;
•timing of stock-based compensation expense; and
•general economic and political conditions and government regulations in the United States and Canada and the countries where we may expand in the future, macroeconomic such as the COVID-19 pandemic, rising inflation and interest rates, uncertain credit and global financial markets, recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, supply chain disruption and geopolitical conditions, including the conflict between Russia and Ukraine and related sanctions.
The impact of one or more of the foregoing and other factors may cause our operating results to vary significantly. As such, we believe that quarter-to-quarter comparisons of our operating results may not be meaningful and should not be relied upon as an indication of future performance. If we fail to meet or exceed the expectations of investors or securities analysts, then the trading price of our common stock could fall substantially, and we could face costly lawsuits, including securities class action suits.
Further increases in costs, disruption of supply, or shortage of materials, particularly lithium-ion cells, wiring harnesses, and drivetrain components could continue to harm our business.
We may experience, and in 2021 and 2022 have experienced and continue to experience, increases in the cost of, or a sustained interruption in the supply of or shortage of materials necessary for, the production, maintenance and service of our transit buses, battery systems, electrification and charging solutions, fleet and energy management systems, and related technologies. For example, our vehicle and equipment deliveries were
impacted by constraints and inefficiencies in production driven by shortages in component parts, particularly resin for connectors, wiring harnesses, and certain drivetrain components, resulting in part from global supply chain disruptions stemming from the effects of the Covid 19 pandemic and in part from challenges particular to certain vendors. These delays have caused temporary shutdowns of our production lines, and have caused delays in production and incremental shipping costs for air freight. Further, if suppliers impose unfavorable credit term as a result of our current financial condition, this could restrict our ability to secure parts and limit our production. Any such increases in cost, including due to inflation, supply interruption, materials shortages, or an increase in freight and logistics costs, our unfavorable credit terms with suppliers could adversely impact our business, prospects, financial condition and operating results.
Our suppliers also use various materials, including aluminum, carbon fiber, lithium, cobalt, nickel, copper and neodymium. The prices and supply of these materials may fluctuate, depending on market conditions, geopolitical risks, such as the conflict in Ukraine and the resulting sanctions on Russia and Belarus, fluctuations in currency exchange rates, and global supply and demand for these materials, including increased production of electric transit buses and other energy storage applications by our competitors and companies in adjacent markets such as passenger cars and stationary storage. Our contracts do not all have mechanisms in place that allow us to raise prices to the end customer due to inflation or other material cost increases. If we are not able to raise our prices to our end customers, inflationary pressures and other material cost increases could, in turn, negatively impact our operating results.
Moreover, we are subject to risks and uncertainties associated with changing economic, political, and other conditions in foreign countries such as disruptions due to geopolitical turmoil, including the conflict between Russia and Ukraine and related sanctions, and due to the ongoing COVID-19 pandemic and related global supply chain disruptions, increased import duties, tariffs, and trade restrictions. Unavailability or delay of imports from our suppliers have caused and may in the future cause interruptions in our supply chain and increase our costs of procurement. Even if we do not have suppliers in Ukraine or other countries affected directly by such conflict, companies that can no longer rely on suppliers in countries affected by the conflict may look to suppliers in other parts of the world, including the suppliers from which we source materials. Consequently, we may experience increased competition for materials, which could further increase the cost to us of sourcing materials and negatively impact our ability to source parts from our current suppliers and from identifying and working with new suppliers.
Our business is dependent on reliable availability of lithium-ion cells for our battery packs. While we believe other sources of lithium-ion cells will be available for our battery packs, to date, we have only used one supplier for lithium-ion cells for the battery packs used in commercial applications for our Proterra Transit and Proterra Powered customers. As we increase battery pack production, there is no guarantee that our current cell supplier will be able to supply the volume that we will require to meet growing demand. Battery cell demand continues to increase across vehicle segments including passenger car, and new incentives and tax credits under the Inflation Reduction Act, which became law in August 2022, may further accelerate demand and competition for cell supply. Any disruption in the supply of battery cells could disrupt production of our battery systems and electric transit buses until we are able to find a different supplier that can meet our specifications and production demands. Such disruption could have an adverse effect on our business, prospects, financial condition and operating results.
We expect raw material prices to remain elevated in the foreseeable future due to inflation and continued global supply chain issues. While we believe our exposure to increased costs is no greater than the industry as a whole, our business and results of operations may be adversely affected if our efforts to mitigate their effects are unsuccessful. Substantial increases in the prices for our materials or prices charged to us, particularly those charged by lithium-ion cell suppliers or charger hardware providers, would increase our operating costs and could reduce our margins if we cannot recoup the increased costs through increased sale prices on our battery systems, vehicles or charging systems. Furthermore, fluctuations in fuel costs, or other economic conditions, may cause us to experience significant increases in freight charges and material costs. Additionally, because the negotiated price of an existing battery system, vehicle or charging system is established at the outset, we, rather than our customers, bear the economic risk of increases in the cost of materials. Moreover, any attempts to increase battery system, vehicle or charging system prices in response to increased material costs could increase the difficulty of selling our electric transit buses or battery systems at attractive prices to new and existing customers and lead to cancellations of customer orders. If we are unable to effectively manage our supply chain and respond to disruptions to our supply chain in a cost-efficient manner, we may fail to achieve the financial
results we expect or that financial analysts and investors expect, and our business, prospects, financial condition and operating results may be adversely affected.
Our recent workforce reduction and planned closure of our City of Industry facility may not be as successful as anticipated and may not improve overall efficiency.
On January 20, 2023, we implemented a reduction-in-force and announced the closure of our City of Industry facility, which we expect to vacate by the end of 2023. While we believe this will improve operational efficiency and expect to realize cost reductions, we may not be able to realize the full benefits within the anticipated time frame, or at all. We may also incur other charges, costs, future cash expenditures or impairments not currently contemplated due to events that may occur as a result of, or in connection with the reduction in workforce and facility closure. Further, we may experience unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond our intended reduction-in-force, a reduction in morale among our remaining employees, and the risk that we may not achieve the anticipated benefits, all of which may have an adverse effect on our results of operations or financial condition.
While we have implemented, and intend to continue to implement, cost-reduction strategies in order to meet our profitability goals, if we do not achieve expected savings or if operating costs increase as a result of investments in strategic initiatives, our total operating costs would be greater than anticipated. We may also incur substantial costs or cost overruns in utilizing and increasing our production capability, particularly if we build new battery production lines, and if we vertically integrate subsystem production into our manufacturing facilities. In addition, if we do not manage cost-reduction efforts properly, such efforts may affect the quality of our products and our ability to generate future revenue. Moreover, significant portions of our operating expenses are fixed costs that will neither increase nor decrease proportionately with revenue. In addition, we incur significant costs related to procuring the materials required to manufacture our battery systems, electrification and charging solutions, fleet and energy management systems and electric transit buses, as well as assembling electric transit buses and systems, and compensating our personnel. If we are not able to implement further cost-reduction efforts or reduce our fixed costs sufficiently in response to a decline in revenue, our business, prospects, financial condition, and operating results may be adversely affected.
Because many of the markets in which we compete are new and rapidly evolving, including possible consolidation of industry players, it is difficult to forecast long-term end-customer adoption rates and demand for our products, and our ability to meet demand for our products.
We are pursuing opportunities in markets that are undergoing rapid changes, including technological and regulatory changes, and it is difficult to predict the timing and size of the opportunities. There may be ongoing consolidation of industry players which could impact market demand for our products and competition for electrification solutions. For example, in October 2022 Nikola Corporation, a customer, completed an acquisition of Romeo Power, a competitor. Commercial vehicle battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, represent complex products and services. Because these automotive systems depend on technology from many companies, commercialization of commercial vehicle electrification products could be delayed or impaired due to unavailability of technology or integration challenges inherent in the use of multiple vendors in commercial vehicle production. Although we currently have contracts with several commercial customers, these companies may not be able to implement our technology immediately, or at all. Some of our commercial customers are emerging companies that may not be able to commercialize their products on the production timelines they contemplated when entering into a contract with us, or at all. In 2022, we renegotiated production volumes and minimum order penalties for some customers, and any future inability of customers to meet contract commitments could adversely affect our business and financial results.
In addition, regulatory, safety or reliability requirements, many of which are outside of our control, could also cause delays or otherwise impair commercial adoption of these new technologies, which will adversely affect our growth. Our future financial performance will depend on our ability to make timely investments in the correct market opportunities. If one or more of these markets experience a shift in customer or prospective customer demand, our products may not compete as effectively, if at all. It is also possible that we may not be able to meet demand, and lose customer or prospective customer confidence as a result and lose business to competitors. In the evolving nature of the markets in which we operate, it is difficult to predict customer demand or adoption rates
for our products or the future growth of the markets in which we operate. If demand does not develop or if we cannot accurately forecast customer demand, the size of our markets, or our future financial results, our business, prospects, financial condition, and operating results could be adversely affected.
If our battery systems, electrification and charging solutions, electric transit buses, fleet and energy management software, or other products have product defects and if our customer service is not effective in addressing customer concerns, our ability to develop, market and sell our products and services could be harmed.
Our battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses have in the past contained, and may in the future contain, product defects. Due to the limited deployment of our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, there may be latent problems with our products that have not yet been discovered.
We have in the past found defects in our battery systems, electric transit buses, and charging systems. We may in the future find additional design and manufacturing defects that cause our products to require repair or not perform as expected. While we perform our own and in some cases third-party testing on the products we manufacture, we currently have a limited amount of customer operating experience with our battery systems, drivetrains, high-voltage systems, electric transit buses, software systems, and charging solutions by which to evaluate detailed long-term quality, reliability, durability, and performance characteristics of these products and solutions. There can be no assurance that we will be able to detect and fix any defects in our products prior to their sale to or operation by customers. Our efforts to remedy any issues may not be timely, may hamper production, or may not be satisfactory to our customers. Further, our business has grown rapidly in recent periods, and we may not be able to scale our service organization or partner with an existing service network quickly enough to satisfactorily provide timely customer service and address product defects, customer complaints, and warranty issues, which could result in customer dissatisfaction and negatively impact further sales.
Any product defects, delays, or legal restrictions on our products, or other failure of our products to perform as expected could harm our reputation, negatively impact our ability to market and sell our products, and result in delivery delays, product recalls, product liability claims, customer contract terminations, adverse regulatory actions, and significant warranty and other expenses, and could have an adverse effect on our business, prospects, financial condition, and operating results.
Our battery packs use of lithium-ion cells, which have been observed to catch fire, and our charging solutions operate at high voltages which may cause concerns regarding the use of battery systems, electrification and charging solutions and fleet and energy management software in public transit and other commercial vehicles.
The battery packs that we produce make use of lithium-ion cells. On rare occasions, it is possible for lithium-ion cells to rapidly release contained energy by venting smoke and flames in a manner that can ignite nearby materials as well as other lithium-ion cells. Highly publicized incidents of laptop computers and cell phones containing lithium-ion batteries bursting into flames have focused consumer attention on the safety of these cells. Fires have also been reported in electric cars and transit buses using lithium-ion batteries, including one of our transit buses. These events have raised questions about the suitability of using lithium-ion cells for commercial vehicle applications.
Despite the safety features that we design into our battery packs, there has been, and could be a failure of the battery packs in our buses or battery packs that we may produce for third parties. In November 2022, we experienced the first known fire on a Proterra transit bus that involved our proprietary battery system. There were no injuries and no known property damage, other than to exterior parts of the bus near the thermal event and the involved battery pack. After investigation we issued a recall for a limited number of battery packs. Incidents such as the November 2022 event could subject us to lawsuits, product recalls, cancelled contracts, lost customers, and potentially slow market adoption of our electric transit buses by transit authorities and our technologies by other customers. Also, negative public perceptions regarding the suitability of lithium-ion cells for commercial vehicle applications or any future incident involving lithium-ion cells, such as a vehicle or other fires, particularly
public transit vehicle incidents, even if unrelated to our products, could have an adverse effect on our business, prospects, financial condition, and operating results.
In addition to thermal risk related to battery packs, related accessories and ancillary products could also be subject to similar safety concerns and risks as a result of the high voltage they carry and transmit. Our charging solutions also operate at high voltages and charging equipment must be properly maintained. In the past, our legacy single blade chargers have experienced charger fires which caused damage to the chargers and the bus. In particular, we experienced four such thermal incidents related to our legacy overhead single blade chargers over 2019 and 2020, including one incident in which a charger was completely destroyed. While none of these events resulted in personal injury or significant property damage to the bus or other property, it is possible that other such or related incidents could occur in the future, or that such thermal discharge could result in personal injury or property damage.
We also store a significant number of lithium-ion cells and design, test, and produce battery modules and packs at our manufacturing facilities and other locations. While we have implemented safety procedures for handling cells, we may experience a safety issue or fire related to the cells. Once we ship our customers battery systems, those systems are out of immediate control. Any mishandling of battery systems or equipment failures in our operations or in our customers operations may cause accidents that could potentially harm our employees or third parties or result in disruptions to our business or our customers’ business. While we have implemented safety procedures and require our customers to implement safety procedures, we or our customers could experience a safety issue or fire which could disrupt operations or cause injuries and could have an adverse effect on our business, prospects, financial condition, and operating results.
Defects in the materials or workmanship of our composite bus bodies could harm our reputation, expose us to product warranty or other liability claims, decrease demand for our buses, or materially harm existing or prospective customer relationships.
We are one of a small number of transit bus manufacturers to use a composite unibody for our electric transit buses. In the past, we have sourced composite bus bodies from three suppliers, and now use only one supplier. Defects in the composite body, including non-structural concerns, whether caused by design, engineering, materials, manufacturing errors, or deficiencies in manufacturing or quality control processes at our suppliers, are an inherent risk in manufacturing technically advanced products for new applications. We offer our customers a twelve-year warranty on the composite bus body structure and bear the risk of possible defects. We have experienced defects in some bus bodies and have had to make repairs. For example, in October 2018 we discovered cracking in the wheel wells on some of our buses which required us to repair these defects under our warranty and will increase our field and customer service costs. In addition, in 2020 and 2021, we discovered a manufacturing quality issue that required us to repair laminate cracks that occurred near door frames of certain customer buses, and we expect that we will have to make more of these types of repairs. In 2020, we filed a recall related to the attachment of a torque limiter plate to the composite bus body that did not have proper adhesive application and could compromise the steering gear box and steering of the vehicle. In 2022, we voluntarily filed a new recall on the same issue for a new population of buses. Certain customers have experienced superficial cracking in the exterior gel coat or skin coat of the composite body which has caused certain customers to remove buses from revenue service and required us to develop inspection criteria and repair protocols, when applicable. We have also had to address vehicle inspection guidelines that are designed for metal frame buses with chassis and are not necessarily applicable to composite unibody architecture. Though these defects have not materially impacted us to date, we expect to continue to address these issues, and these defects or future defects with our advanced body materials whether structural or not may harm our existing and prospective customer relationships, damage our brand, and result in a reduction of awards, customer contract terminations, adverse regulatory actions, increased warranty claims, product liability claims and other damages.
Our most recent business expansion with Proterra Powered and Proterra Energy may not be as successful as anticipated, may not attract the customers and business partners we expect, and the assumptions underlying the growth prospects of these businesses may not prove to be accurate.
We have recently introduced and, in the future may introduce, new services and products that our customers and prospective customers may not utilize to the extent we anticipate or at all. For example, Proterra Powered and Proterra Energy products and services are designed to simplify the complexities of electric vehicle energy
delivery and the deployment of large electric vehicle fleets for our customers. Through these businesses, we offer to design, build, finance, operate, and maintain the energy ecosystem that we believe to be required to power commercial electric vehicles. We have made, and will continue to be required to make, significant investments to scale these businesses, but we cannot be certain that such investments will be successful or meet the needs of our customers. Moreover, even if our customers use these services, we may encounter new challenges related to the delivery of energy solutions and competition from companies that may be better positioned to provide energy management services. If we invest in services or products that are not adopted by our customers or fail to invest in new services and products that meet the needs of our customers, our business, prospects, financial condition, and operating results could be adversely affected. In addition, we have limited history operating these businesses and providing the products and services they offer. There can be no assurances that these products and services will be accepted by our customers, or that we will effectively be able to market and sell them to existing customers, especially our transit customers who comprise the vast majority of our current revenues. Further, the limited experience we have acquired operating Proterra Transit may not prove to be applicable to Proterra Powered and Proterra Energy.
We expect Proterra Powered and Proterra Energy product lines to account for a growing percentage of our revenue in the future, and it is possible that certain assumptions underlying the launch of these businesses are subsequently determined to be inaccurate, such as assumptions regarding the growing adoption of electrification by commercial vehicle manufacturers and their customers in general; the attractiveness of our products and services to OEMs that would use our battery systems, electric drivetrains, high-voltage systems, vehicle controls, telemetry gateways, charging solutions, software and telematics platforms and related technologies in their electric transit buses or elsewhere; government and regulatory initiatives and directives impacting the adoption of electrification technologies for commercial vehicle applications; and the overall reliance by enterprises on commercial vehicles and the demand for medium- and heavy-duty trucks in the future.
We face intense and increasing competition in the transit bus market and may not be able to compete successfully against current and future competitors, which could adversely affect our business, revenue growth, and market share.
The transit bus industry is relationship driven and dominated by incumbent companies that have served their respective markets longer than we have. In the transit bus industry, our main sources of competition are incumbent transit vehicle integrators that have served our market with legacy diesel, diesel-hybrid and compressed natural gas products for many years, such as NFI Group Inc., Gillig Corporation, and Nova Bus Company; BYD Company Ltd., a Chinese company that offers an array of vehicles and other products, including electric transit vehicles; and new entrants and companies in adjacent markets, including other vehicle manufacturers that have entered or are reported to have plans to enter the transit bus market.
In the transit bus industry, electric bus procurements still represent a minority of annual transit bus purchases. As the number of electric bus OEMs increases, we may not be able to maintain our leading market position in North America. We also may not be successful in competing against incumbent competitors that have longer histories of serving the transit bus market and established track records of service, or with much larger, well-funded companies that choose to invest in the electric transit bus market. As more established bus companies develop their electric vehicle or competing zero-emission solutions, their long history in the transit sector could prove to be a competitive advantage which may have a negative impact on our ability to compete with them. Moreover, our competitors that also manufacture diesel-hybrid and compressed natural gas vehicles may have an advantage with their existing and prospective customers that are interested in exploring diesel alternatives without committing to electric vehicles or to pursue a gradual electrification strategy with the same manufacturer. Additionally, these competitors have more experience with the procurement process of public transit authorities, including bid protests. Competitors, potential customers, or regulators may also make claims that our electric transit buses or competitive bid activity are not in compliance with laws, regulatory requirements, or industry standards, which may impact our ability to sell our electric transit buses and to compete successfully for current and future customers. Actions by competitors may have consequences for future business or effects that we have not anticipated on other future opportunities.
We face intense and increasing competition in the commercial vehicle electrification market and may not be able to compete successfully against current and future competitors, which could adversely affect our business, revenue growth, and market share.
The electric powertrain, electric commercial vehicle and charging solutions industries are highly competitive. We may not be successful in competing against companies in the battery systems, electric powertrain, charging solutions and related industries who may have more resources than we do or who are able to produce products and deliver services that are perceived by the market to be superior to ours. Global battery makers in particular may be able to leverage their superior scale and access to capital to sell their products more effectively to potential customers and may be further incentivized to compete with us in the North American market to take advantage of new incentives and tax credits for commercial vehicle electrification in the Inflation Reduction Act, which became law in August 2022. We may also face competitive pressure from incumbent vehicle producers that decide to enter the battery system or electric powertrain business, or vertically integrate their supply chain, and that are able to leverage their superior resources and capital to produce products that perform or are priced competitively when compared to our own.
In the battery system and electric powertrain industry, our main sources of competition include large Chinese battery suppliers such as CATL; incumbent tier one automotive suppliers that are developing electric powertrain alternatives to internal combustion engines, such as Cummins, Allison Transmission, BorgWarner and Dana; and commercial vehicle manufacturers that are developing or may develop their own internal electric powertrain solutions for their vehicles including large automotive companies, such as Daimler Truck Group and Volvo Group. In the future, incumbents and new companies offering competing zero emission solutions such as fuel cell electric vehicles may also become significant competitors.
In the charging solutions industry, our main sources of competition are incumbent charging solutions providers that develop charging solutions for commercial vehicles such as Siemens, ABB, Heliox, ChargePoint and Rhombus; and software companies that offer charging management solutions and can partner with hardware providers to provide complete solutions to end customers.
These competitors may have greater financial, technical, manufacturing, marketing, sales, and other resources than we do, and may have more experience and ability to devote greater resources to designing, developing, testing, manufacturing, distributing, deploying, promoting, selling or supporting battery systems, electrification and charging solutions, fleet and energy management software, and related technologies. Similarly, our principal competitors that also design, test, manufacture and deploy battery systems, electrification and charging solutions, fleet and energy management systems and related technologies for passenger vehicles may have a competitive advantage, through their established distribution and service networks for legacy vehicle technology, brand recognition and market acceptance of their products and services, and perceived reliability or popularity, all of which could be attractive to prospective partners and manufacturers that are exploring commercial vehicle electrification alternatives. As a result, our current and potential competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards, or customer requirements, or devote greater resources than we can to the development, promotion, distribution and sale of their products and services. Our competitors and potential competitors may also be able to develop products or services that are equal or superior to ours, achieve greater market acceptance of their products and services, and increase sales by utilizing different distribution channels than we do. Some of our competitors may aggressively discount their products and services in order to gain market share, which could result in pricing pressures, reduced profit margins, lost market share, or a failure to grow market share for us. As the market for commercial electric vehicles grows and battery systems, electrification and charging solutions, fleet and energy management software, and related technologies gain wider adoption, we expect that additional specialized providers of battery systems, electric powertrain technology, charging infrastructure, and related software solutions and related technologies will enter the markets that we address and that larger competitors could more effectively sell their offerings.
In addition, we developed our battery system and powertrain systems and related components to be compliant with “Buy America” regulations applicable to the transit business, which means that we may have higher costs to procure components, and design, test and manufacture such products in the United States than competitors that are not compliant with Buy America or similar regulations. Our competitors may be able to manufacture comparable or competitive products in more cost-effective jurisdictions and import them to the United
States at prices lower than ours, which competition could cause us to lose market share or compel us to reduce prices for goods or services to remain competitive, which could result in reduced sales and revenue in industry segments that are not subject to Buy America or similar regulation. The production of battery systems, electrification and charging solutions, fleet and energy management systems, and related technologies in China, where production costs are lower and where the development of such technologies could be subsidized by the state, could negatively impact our competitive profile by presenting our customers and partners a more cost-effective alternative to our products and services, which could result in reduced sales and revenue and loss of market share or compel us to reduce prices for goods or services to remain competitive.
Moreover, current and future competitors may also make strategic acquisitions or establish cooperative relationships among themselves or with others, including our current or future suppliers or business partners. By doing so, these competitors may increase their ability to meet the needs of our customers or potential customers. These developments could limit our ability to generate revenue from existing and new customers. If we are unable to compete successfully against current and future competitors, our business, prospects, financial condition, and operating results would be adversely affected.
Our suppliers have and may fail in the future to deliver components according to schedules, prices, quality and volumes that are acceptable to us, or we may be unable to manage these suppliers effectively.
Some of our products contain thousands of parts that we purchase from hundreds of mostly single-source direct suppliers, generally without long-term supply agreements. This exposes us to multiple potential sources of component shortages. Unexpected changes in business conditions, materials pricing, labor issues, wars, governmental changes, tariffs, natural disasters, health epidemics such as the global COVID-19 pandemic and its related disruption of global supply chains, particularly in the industrial sector, and other factors beyond our or our suppliers’ control could also affect these suppliers’ ability to deliver components to us or to remain solvent and operational. Single source suppliers provide us with a number of components that are required for manufacturing of our current products, including our composite bus bodies. If a single source supplier was to go out of business, we might be unable to find a replacement for such source in a timely manner, or at all. If a single source supplier were to be acquired by a competitor, that competitor may elect not to sell to us in the future. We have experienced and continue to experience component shortages and delays, including resin for connectors and wiring harnesses. In the fourth quarter of 2022, difficulty sourcing wiring harnesses from a vendor resulted in our production delays and fewer buses delivered in that quarter. In the first quarter of 2023, we experienced a shortage in a component used to complete our battery packs, temporarily idling our manufacturing lines in City of Industry. The unavailability of any component or supplier has in the past, and could in the future result in production delays, idle manufacturing facilities, require product design changes, cause loss of access to important technology and tools for producing and supporting our products, and create delays in providing replacement parts to our customers. We have also experienced delays in sourcing replacement parts for some of our oldest transit buses in customer fleets, which has led to customer dissatisfaction and buses being out of service for lengthy periods while awaiting replacement parts.
Moreover, significant increases in our production, or product design changes made by us have required and may in the future require us to procure additional components in a short amount of time. Our suppliers may not be able to sustainably meet our timelines or our cost, quality and volume needs, or may increase prices to do so, requiring us to replace them with other sources. Our supply for battery cells and other raw materials is critical in allowing us to scale our operations and meet our growth profitability and cash flow targets, such that any supply delay or vulnerability in the battery cell supply chain could alter our growth plans. Further, we have limited manufacturing experience and we may experience issues increasing the level of localized procurement at our current or future facilities. While we have to date secured additional or alternate sources or developed our own replacements for many of our components, and we believe that we will be able to continue to do so, there is no assurance that we will be able to do so quickly or at all, particularly with highly customized components. Additionally, we may be unsuccessful in our continuous efforts to negotiate with existing suppliers to obtain cost reductions and avoid unfavorable changes to terms, source less expensive suppliers for certain parts, and redesign certain parts to make them less expensive to produce. Any of these occurrences may harm our business, prospects, financial condition and operating results.
As the scale of our production increases, we will also need to accurately forecast, purchase, warehouse and transport components at high volumes to our manufacturing facilities across the United States. If we are unable to
accurately match the timing and quantities of component purchases to our actual needs or successfully implement automation, inventory management and other systems to accommodate the increased complexity in our supply chain and parts management, we may incur unexpected production disruption, storage, transportation and write-off costs, which may harm our business and operating results.
Our dependence on a limited number of suppliers introduces significant risk that could have adverse effects on our financial condition and operating results.
We are a relatively low-volume producer of battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses, and related technologies, and do not have significant purchasing power with suppliers in the electric vehicle market for many components of our products, including batteries, drivetrains, high-voltage systems and electric transit buses. As a result, suppliers and other third parties may be less likely to invest time and resources in developing business relationships with us if they are not convinced that our business will succeed. Larger suppliers have in the past and may in the future require minimum order quantities from us, which can expose us to liquidated damages or substantial penalties. For example, in 2022, we incurred nearly $8 million in penalties owed to our bus body supplier.
To build and maintain our business and obtain favorable contract terms, we must maintain our suppliers’ and other vendors’ confidence in our stability, liquidity, and business prospects. Maintaining such confidence may be complicated by certain factors, such as our limited operating history, suppliers’ unfamiliarity with our products, competition, and uncertainty regarding the future of commercial vehicle electrification. Some of these factors are outside of our control and any negative perception about our business prospects, even if exaggerated or unfounded, would likely harm our business and make it more difficult to contract with suppliers on favorable terms. In addition, some of our suppliers may have more established relationships with our competitors, and as a result of those relationships, some suppliers may choose to limit or terminate their relationship with us.
In addition, with respect to our battery manufacturing operations that supports Proterra Transit and Proterra Powered, our battery production volumes are relatively small and we are currently sole sourcing key components from select suppliers, such as LG Energy Solution, for the lithium-ion cells that we use to manufacture our battery packs and other sole source suppliers for key elements of the battery pack. Disruptions in production may result if we had to replace any of these sole source suppliers on short notice. As we increase battery production volumes, if our current sole source suppliers cannot meet our demand for increased supply, we may find our ability to grow our business constrained if there are not alternative sources of supply that we can secure in a timely fashion, or at all.
With respect to our transit business, we have few long-term agreements with suppliers and typically purchase supplies on an order-by-order basis depending on the material requirements to build customers’ buses. In many cases, we rely on a small group of suppliers, many of which are single-source suppliers, to provide us with components for our products, such as our bus body, which we sole source from TPI Composites Inc, and components of our drivetrains. Moreover, transit bus customers have specified a certain supplier for components, such as its preferred seating or heating, ventilation, and air conditioning units, and we are then beholden to that specified supplier’s terms and delivery schedule. While we obtain components from multiple sources when that is a viable alternative, certain components used in our electric transit buses, such as bus bodies sourced from TPI Composites, must be custom made for us. In 2022 and into early 2023 we sourced wiring harnesses for our transit and powertrain products largely from one vendor that has recently experienced challenges and financial instability in its business, which created disruption in our supply and slowed our production.
If these suppliers become unwilling or unable to provide components, there may be few alternatives for supply of specific components, such as wiring harnesses, which may not be available to us on acceptable terms or favorable prices, or that meet our published specifications in a timely manner or at all. We have experienced in the past, may again experience delays while we qualify new suppliers and validate their components. In addition, replacing our sole source suppliers may require us to reengineer our products, which could be time consuming and costly.
Our reliance on a small group of sole-source suppliers as well as certain suppliers specifically chosen by customers creates multiple potential sources of delivery failure or component shortages for the production of our products. As a result, we have in the past, and may be required to in the future renegotiate our existing
agreements with our suppliers, potentially with less favorable terms, and incur additional costs associated with the production. In the past, we have experienced delays related to supply shortages, including, most recently, as a result of the global supply chain disruptions related to the COVID-19 pandemic, and untimely or unsatisfactory delivery of components, including cells, wiring harnesses and other drivetrain components, that have stalled production with respect to our electric transit buses and our battery systems. Moreover, although we continue to expend significant time and resources vetting and managing suppliers and sourcing alternatives, we may experience future interruptions in our supply chain. Failure by our suppliers to provide components for our electric transit buses, battery systems or other products has in the past, and could in the future,severely restrict our ability to manufacture our products and prevent us from fulfilling customer orders in a timely fashion, which could harm our relationships with our customers and result in contract fines, negative publicity, damage to our reputation, and adverse effects on our business, prospects, financial condition, and operating results.
We have been and may continue to be impacted by macroeconomic conditions, rising inflation rates, uncertain credit and global financial market, including recent and potential bank failures, supply chain disruption and geopolitical events, such as the conflict between Russia and Ukraine.
In recent years, the United States and other significant markets have experienced cyclical downturns and worldwide economic conditions remain uncertain, including downturns of economic displacement related to COVID-19 or other similar pandemics and the current conflict between Russia and Ukraine. Economic uncertainty and associated macroeconomic conditions, including high volatility and uncertainty in the capital markets including as a result of inflation and interest rate spikes and recent and potential disruptions in access to bank deposits or lending commitments due to bank failures, make it difficult for our customers and us to accurately forecast and plan future business activities, and could cause our customers to slow spending on our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, which could delay and lengthen sales cycles. Furthermore, during uncertain economic times our customers may face issues gaining timely access to sufficient funding, which could result in an impairment of their ability to make timely payments to us. If that were to occur, we may be required to increase our allowance for doubtful accounts and our results could be negatively impacted. A weak or declining economy could also strain our suppliers, possibly resulting in supply disruption. In addition, there is a risk that our current or future suppliers, service providers, manufacturers or other partners may not survive such difficult economic times, which would directly affect our ability to attain our operating goals on schedule and on budget.
A significant downturn in economic activity, or general spending on transit or commercial vehicle electrification technologies, may cause our current or potential customers to react by reducing their capital and operating expenditures in general or by specifically reducing their spending on electric commercial vehicles and related technologies. In addition, our customers may delay or cancel projects to upgrade or replace existing vehicles in their fleets, or other projects to electrify commercial vehicle fleets, with our products or seek to lower their costs by renegotiating contracts. Moreover, competitors may respond to challenging market conditions by lowering prices and attempting to lure away our customers.
Given the global nature of our supply chain and customer base, global political, economic, and other conditions, including geopolitical risks such as the current conflict between Russia and Ukraine and related sanctions, may adversely affect our business and results of operations in ways we cannot foresee at the outset. War and economic dislocations may spur recessions, economic downturns, slowing economic growth and social and political instability; commodity shortages, supply chain risks and price increases; instability in U.S. and global capital and credit markets which could impact us, our suppliers and customers; and currency exchange rate fluctuations among other impacts that adversely affect our business or results of operations.
We cannot predict the timing, strength, or duration of any economic slowdown or any subsequent recovery generally, or in any industry. If the conditions in the general economy and the markets in which we operate worsen from present levels, our business, financial condition, and operating results could be adversely affected.
Our transit business is significantly dependent on government funding for public transit, and the unavailability, reduction, or elimination of government economic incentives would have an adverse effect on our business, prospects, financial condition, and operating results.
Our principal transit customers are transit authorities that depend on government funding and programs authorized for public transportation under Title 49, Chapter 53 of the U.S. Code, and administered by the FTA, including Urbanized Area Formula Grants, Formula Grants for Rural Areas, the Capital Investment Program, and the Bus and Bus Facilities Program.The Fixing America’s Surface Transportation Act, or FAST Act, enacted in December 2015, allocated over $305 billion for highway, transit, and vehicle safety programs for the five-year period that ended on December 31, 2020. Among other programs, the FAST Act reinstated a competitive Bus and Bus Facilities Infrastructure Investment Program, which grew from $268 million in 2016 to $344 million in 2020, resulting in an 89% increase over the 2015 funding levels for buses and bus facilities. To date, a substantial majority of our customers have received funding through these FAST Act programs in order to purchase new electric transit buses. For example, in 2018, nearly 70% of transit agencies that ordered buses from us were recipients of grants through the Low or No Emission Vehicle Program. The Low or No Emission Vehicle Program has enabled public transit agencies to purchase electric transit buses when the upfront cost of the electric bus was significantly higher than legacy diesel buses and the technology was new to customers. On November 15, 2021, President Biden signed the Infrastructure and Investment Jobs Act (IIJA), also referred to as the “Bipartisan Infrastructure Law”, into law, reauthorizing surface transportation programs through the federal government’s fiscal year in 2026, increasing funding for transit focused programs and establishing additional funding opportunities for no and low emission vehicles at unprecedented levels of funding. In August 2022, the Inflation Reduction Act was signed into law, further expanding incentives for commercial zero emission vehicles including clean vehicle tax credits.
In addition to funding and incentives under the FAST Act and the Bipartisan Infrastructure Law, and the Inflation Reduction Act, certain states and cities offer vouchers for the purchase of electric buses, such as California’s Hybrid & Zero Emission Truck & Voucher Incentive Project, and the New York Truck Voucher Incentive Program. These vouchers provide point-of-sale discounts to vehicle purchasers. Additionally, there are other state programs that help fund electric bus purchases, including California’s Transit and Intercity Rail Capital Program, which has been allocated a portion of California’s Cap-and-Trade funds annually. The California Low Carbon Fuel Standard, or LCFS, also enables transit agencies using electricity as a source of fuel to opt into the LCFS program and earn credits that can be monetized. While the value of these credits fluctuates, the credits may help to offset up to half of the fuel costs for our transit customers.
There can be no assurance that these programs will be reauthorized following expiration of their current terms, that other government funding programs will continue to be available at the current levels or at all in the future, or that new government funding programs will be adopted, including with respect to products and services that are currently or will in the future be offered by Proterra Powered and Proterra Energy. Uncertainty or delay in extending, renewing, or adopting these incentives beyond their current or future expiration dates could negatively impact our business because sales cycles for public and other transit customers are long and customers may be unwilling to adopt electric technology if supportive funding is not assured. For example, transit authorities have reduced order sizes in the past because of a decrease in available funding.
Available government funding and economic incentives are subject to change for a variety of reasons that are beyond our control, including budget and the policy initiatives and priorities of current and future administrations at the federal and state level. In addition, future government shutdowns may impact the availability and administration of government funding, which could adversely impact future bus orders and result in payment delays for existing orders. For example, we experienced payment delays from customers during the U.S. federal government shutdown in January 2019 related to the FTA’s inability to administer grant funding during the shutdown. If government support for adoption of electric vehicles and clean energy initiatives wanes, as it did during the Trump Administration, this could adversely affect the growth of the North American public transit electric bus market and the commercial electric vehicle market generally, and could have an adverse effect on our business, prospects, financial condition, and operating results.
Our future growth prospects depend upon the interest of commercial vehicle manufacturers in adopting our products and services that are designed to facilitate the electrification of commercial vehicles.
Our growth is highly dependent upon the adoption of our battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses by commercial vehicle manufacturers and OEMs, and their willingness to partner with us on the design, development, testing, manufacturing, distribution, deployment, promotion, sale, and support of our products. The market for commercial electric vehicles and electrification technologies is relatively new, rapidly evolving, and characterized by rapidly changing technologies, price competition, additional competitors, evolving government regulation and industry standards, frequent new product and vehicle announcements, and changing demands and behaviors of customers and potential partners. For example, in August 2022, the Inflation Reduction Act passed in the United States, adding unprecedented funding opportunities and tax credits for passenger car and commercial vehicle electrification, could make the United States an attractive market for vehicle electrification and increase competition as more industry players enter our core market. As a result, we spend resources educating our potential customers and partners on the benefits of adopting electric vehicle technology and engaging in lobbying efforts to promote clean energy initiatives that benefit our business activities.
Other factors that may influence the adoption of our commercial vehicle electrification technologies by manufacturers and OEMs include:
•perceptions about commercial electric vehicle performance, total cost of ownership, design, quality, cost and reliability that may be attributed to the use of advanced technology (in particular with respect to lithium-ion battery packs), especially if adverse events or accidents occur that are linked to the quality or safety of commercial electric vehicles;
•the amount and availability of federal, state, or other government funding and, in particular, the availability of economic incentives promoting fuel efficiency and alternate forms of energy, such as the Low or No Emission Vehicle Program, the Advanced Technology Vehicle Manufacturing Loan Program and the tax credits in the Inflation Reduction Act;
•the range over which commercial electric vehicles may be driven on a single battery charge and the time it takes to recharge the batteries of these vehicles;
•the cost and feasibility of installing new charging infrastructure;
•concerns about electric grid capacity and reliability, the cost of electricity, and reliance of utilities on fossil fuels for electricity generation, which could derail our past and present efforts to promote commercial electric vehicles as a practical substitution for vehicles that require fossil fuels;
•the availability of alternative fuel vehicles, including diesel-hybrid and compressed natural gas vehicles, and battery electric fuel cell vehicles;
•improvements in the fuel economy of the internal combustion engine;
•perceptions about the impact of electric vehicles on the environment and the health and welfare of communities;
•perceptions about the use of electric batteries, sourcing of battery components, recyclability, and safe disposal of batteries;
•the availability of service for commercial electric vehicles;
•the environmental consciousness of corporations and public agencies;
•volatility in the cost of diesel fuel and oil;
•government regulations;
•social and political support for clean energy initiatives and commercial electric vehicles;
•perceptions about and the actual cost of alternative fuel vehicles; and
•macroeconomic factors.
Moreover, the willingness of commercial vehicle manufacturers and OEMs to embrace our battery systems, electrification and charging solutions, fleet and energy management software, and related technologies depends, in part, on the real or perceived reliability of these products and services, and their ability to provide complete electrification solutions to potential customers. Any lapse in quality, reliability or performance of any of these products or services could harm the perception of our other products and negatively impact the adoption of our products or services.
Any of the factors described above may cause current or potential customers not to purchase or adopt our products or services. If the market for commercial electric vehicles does not develop as we expect or develops more slowly than we expect, our business, prospects, financial condition, and operating results could be adversely affected.
The growth of our transit business is dependent upon the willingness of corporate and other public transportation providers to adopt and fund the purchase of electric vehicles for mass transit.
The growth of our transit business is highly dependent upon the adoption of electric transit buses for mass transit by corporate and public transportation providers. The market for electric transit buses is relatively new, rapidly evolving, and characterized by rapidly changing technologies, price competition, additional competitors, evolving government regulation and industry standards, frequent new vehicle announcements, and changing demands and behaviors of riders. As a result, we spend resources educating our potential customers on the benefits of adopting electric vehicle technology and engaging in lobbying efforts to promote clean energy initiatives.
The same factors described above that may influence the adoption of our commercial vehicle electrification technologies by manufacturers and OEMs, also may influence the adoption of electric transit buses by corporate and public transportation providers. Moreover, the willingness of corporate and public transportation providers to embrace electric transit buses depends, in part, on the willingness of users of public transportation to continue to use buses instead of alternative modes of transportation, including private car, rail, and ridesharing services including Uber, Lyft, and electric bikes and scooter services, on-demand shuttles and, in the future, autonomous vehicles. Bus ridership has been severely impacted by the COVID-19 pandemic and has been declining in large transportation markets, which may lead to fewer investments in electric transit buses in the long term.
Any of these factors may cause current or potential corporate and other public transit customers not to purchase our electric transit buses or use our services. If the market for electric vehicles for mass transit does not develop as we expect or develops more slowly than we expect, our business, prospects, financial condition, and operating results could be adversely affected.
If we fail to make the right investment decisions in our technologies and services, we may be at a competitive disadvantage.
Electrification of commercial vehicles is a relatively new field. We have invested significant resources into our technologies, including our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies. For example, we invested in a single-blade overhead charging system that we have deployed and must continue to support for transit customers, even though the industry has moved to other solutions such as overhead pantograph or plug-in charging which also have required, and may continue to require, new investments on our part. In the third quarter of 2022, we made a strategic equity investment in a privately held entity that we expect to manufacture LFP cells domestically for us in the future. However, there is no guarantee that this company will succeed in making cells to our specifications, that we will develop product using these cells, or that we will be successful introducing a product with these cells into the market. If we select and invest in technology or technology standards that are not widely adopted or invest in technologies that are not widely adopted by large customers who influence the industry in the future, we may not
recover our investments in these technologies and may be at a competitive disadvantage, and our business, prospects, financial condition, and operating results could be adversely affected.
We have a long sales, production, and technology development cycle for new public transit customers, which may create fluctuations in whether and when revenue is recognized, may result in unfavorably priced contracts and may have an adverse effect on our business.
The vast majority of our current and historical sales are to transit agencies that do not procure electric transit buses every year. The complexity, expense, and nature of government procurement processes result in a lengthy customer acquisition and sales process. It can take us years to attract, obtain an award from, contract with, and recognize revenue from the sale of a vehicle to a new customer, if we are successful at all. We have in the past entered contracts with customers based on certain assumptions regarding the cost of production, but the buses were produced years after the award was made when costs were much higher and it was unprofitable to fulfil the order. In 2022, we negotiated with several customers to make adjustments in pricing to acknowledge inflation but were not always successful. With long contract cycles we may continue to face this risk in the future even with contract terms that allow for inflation adjustments.
Before awarding an order for electric transit buses, transit agencies generally conduct a comprehensive and competitive proposal process based on a variety of criteria, including technical requirements, reliability, reputation, and price. Even if we are awarded an order, the actual realization and timing of revenue is subject to various contingencies, many of which are beyond our control, including the customer’s interpretation of technical or performance requirements for acceptance, timing and conditions of customer acceptance, and the customer’s reduction, modification, or termination of an order. A customer is not obligated to purchase the electric transit buses and may cancel or modify an award prior to entering into a contract with us. We have in the past, and may in the future, experience customer cancellations or modifications of awards. Customers have in the past , and customers may in the future cancel or modify an award for a variety of reasons, including as a result of improvements in our technology or the technology of our competitors between the dates of award and signed contract, or as the result of a successful bid protest.
Our sales and production cycle for a transit customer can be a long and time-consuming process. The initial sales process from first engagement to award typically ranges from 6 to 18 months. The award of a proposal is typically followed by a pre-production process where the design and specifications of the customized buses are mutually agreed and we negotiate a final contract and purchase order with our customer. Procurement of parts and production typically follow this final agreement between us and the customer. Once a bus is fully manufactured, the customer typically performs a final inspection and determines whether to accept delivery of the bus, at which time we recognize revenue on the sale. In other cases, revenue is recognized upon acceptance by the customer, typically by signing an acceptance document, which can cause delay in revenue recognition. The length of time between a customer award and vehicle acceptance typically varies between 12 and 24 months, depending on product availability, production capacity, and the pre-delivery and post-delivery inspection process by the customer which has in the past resulted in additional changes to the transit bus after manufacturing completion, re-works, further product validation and acceptance periods, and additional costs to us that we may not be able to recover. Consequently, we have in the past, and we may continue to invest significant resources and incur substantial expenses before a customer accepts a bus order and these expenses may not be recovered at all if a customer does not accept the completed bus, the bus requires costly modifications, or we extend additional warranties. For instance, we create a bill of materials and obtain the appropriate parts for each customized bus for a customer, which can result in excessive inventory risk if a customer changes or cancels the order. In addition, we may devote significant management effort to develop potential relationships that do not result in bus orders, acceptance of the bus as delivered, and the corresponding recognition of revenue, and the diversion of that effort may prevent us from pursuing other opportunities. As a result, our long sales and development cycle may subject us to significant risks that could have an adverse effect our business, prospects, financial condition, and operating results.
If we are unable to attract new customers and expand sales to existing customers, our revenue growth could be slower than we expect and our business would be adversely affected.
Our ability to achieve significant future revenue will depend in large part upon our ability both to attract new customers and to expand our sales to existing customers, including sales of Proterra Powered and Proterra
Energy products and services to current and future customers, including Proterra Transit customers. If we fail to attract new customers or fail to maintain and expand our customer relationships, our business would be adversely affected. For example, if our existing transit customers do not expand their orders, our revenue may grow more slowly than expected, may not grow at all, or may decline. Additionally, we have a small direct sales force for each part of our business. We plan to continue expanding our sales efforts, but we cannot be assured that our efforts will result in sales to new customers, or increased sales to existing customers, with respect to our Proterra Powered, Proterra Transit or Proterra Energy offerings. Further, given the small size of our sales team, losing a member of our team may adversely affect our sales efforts with existing or potential new customers. If our efforts to expand sales to our existing customers are not successful, our existing customers do not continue to purchase additional products and services, or we are unable to attract new customers, our business, prospects, financial condition, and operating results would be adversely affected.
We could incur material losses and costs from product warranty claims, recalls, or remediation of electric transit buses for real or perceived deficiencies or from customer satisfaction campaigns.
We provide warranties on our Proterra Transit, Proterra Powered and Proterra Energy hardware products and process warranty claims in the ordinary course of our business. Warranty estimates are inherently uncertain and changes to our historical or projected experience, especially with respect to new battery systems, electrification and charging solutions, fleet and energy management systems or other vehicle technologies, may cause material changes to our warranty reserves in the future. If our warranty reserves are inadequate to cover future warranty claims on our products, our business, prospects, financial condition, and operating results could be adversely affected. In addition, we may also choose to upgrade parts or systems across an entire vehicle fleet or electric drivetrain product line for our own service or customer satisfaction needs, which may result in unforeseen costs.
We provide a limited warranty to customers on battery systems, electric transit buses and charging systems. The limited warranty ranges from one to twelve years depending on the components. Specifically, under the fleet defect provisions included in some transit bus purchase contracts, we are required to establish proactive programs to prevent the re-occurrence of defects in electric transit buses delivered under the contract if the same defect occurs in more than a specified percentage of the fleet within the base warranty period following delivery of the electric transit bus. We calculate an estimate of these costs into each of our contracts based on our historical experience and technical expectations. Warranty reserves include management’s best estimate of the projected costs to repair or to replace items under warranty. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency, and costs of future claims.
Because of the short operating history of our current product line, we have had limited data upon which to base our warranty expense estimates. Also, although we may offer customers lengthy warranties, our ability to recover warranty claims from underlying suppliers may be limited to a shorter period by contract. We are currently aware of warranty claims on certain transit bus structures and components which may result in material warranty costs. For example, we have received warranty claims related to cracked wheel wells and rear door framing in our buses and failures with third-party charging systems installed by us that did not meet customer specifications.
We are potentially subject to recalls of our products to cure real or perceived manufacturing defects or if we fail to comply with applicable U.S. Federal Motor Vehicle Safety Standards, or FMVSS. We have filed voluntary recalls with the United States National Highway Transportation Safety Administration. We are potentially subject to recalls made by the suppliers of components or parts that we purchase and incorporate into our electric transit buses. In October 2018, for example, we initiated a recall on certain of our electric transit buses because of a defect in a brake caliper after an equipment recall by our axle supplier, even though none of our customers had experienced a problem with the part. We may also need to bring battery systems back to our facilities for warranty work and deploy staff to assist customers with battery system issues, and we may need to transport buses back to one of our facilities or retrofit transit buses in the field to address a warranty claim, a recall campaign, or to otherwise satisfy customer concerns, which may require significant staff to be deployed to customer locations.
Even if a defect or perceived defect is not subject to a warranty claim or a current recall process, we may still incur costs of a customer satisfaction campaign when we choose to upgrade our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies without cost to the customer. For example, we are currently aware that the amount of weight on the front axle of certain of our buses in operation may exceed the manufacturer’s gross axle weight rating. To address this issue
with our customers, in 2019 we launched a customer satisfaction campaign to upgrade our electric transit buses’ front axle, which will result in increased labor and parts costs, for which we have accrued a reserve. We are also aware of cracks in the gel coat finish on some of our composite bus bodies which has required and is expected to require customer service support at our cost.
A product warranty claim, product recall, or product remediation, as a result of real or perceived defects, caused by systems or components engineered or manufactured by us or our suppliers, could involve significant expense and could have an adverse effect on our business, prospects, financial condition, and operating results. In addition, adverse publicity or industry rumors and speculation that may result from a customer or customers taking our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies out of service pending a repair or remedy, product warranty claims, or product recalls, could slow market acceptance of our products and have an adverse effect on our reputation, brand image, and our ability to successfully market and sell our products.
If we are unable to scale production and deliver battery systems and buses on time, our business could be adversely affected.
Our business plan calls for significant increases in both vehicle and battery system production in a short amount of time to meet expected delivery dates to customers. Our ability to achieve our production plans will depend upon many factors, including adding additional battery lines, auxiliary vehicle production lines and production shifts, recruiting and training new staff while maintaining our desired quality levels, and improving our vehicle configuration process, supply chain management, and our suppliers’ ability to support our needs. Moreover, because many of our orders are with respect to products that will be delivered more than a year after the order placed, whether we are the battery system supplier or, in the case of electric transit buses, the vehicle OEM, there can be no assurance that we will be able to accurately forecast our supply chain demands or scale our manufacturing accordingly to meet the delivery deadlines for these orders. In addition, we have adopted, and may adopt in the future, new factory and supply chain management technologies and manufacturing and quality control processes, which we must successfully introduce and scale for production across our factories. We have introduced new battery system configurations for our customers and we are new to modifying our production processes to complete different configurations. Moreover, our electric transit buses are customized for our customers and certain battery systems require custom integration with our customer electric transit buses, which means that each new electric transit bus order brings its own set of challenges to vehicle configuration and supply chain. For example, each new electric transit bus configuration may introduce a multitude of parts that we have not used in previous electric transit bus builds, which in turn requires obtaining parts from new suppliers that engineering must validate and incorporate into our vehicle configuration. In the past, we have experienced changes in work instructions for electric transit buses that have not been timely communicated between factories, resulting in recalls of delivered product. We have limited experience developing, manufacturing, selling, servicing, and allocating our available resources among multiple products and multiple factories simultaneously. If we fail to effectively manage the complexity of our production process, our business, prospects, financial condition, and operating results could be adversely affected.
Our inability to deliver electric transit buses that meet customer specifications in a timely manner could significantly delay recognition of revenue and receipt of payment, because we do not recognize revenue and are not paid for electric transit buses until they are delivered to the customer. Moreover, some of our contracts with transit agencies include liquidated damages clauses that apply monetary penalties on a per vehicle per day basis if electric transit buses are not delivered to the customer by the date specified in the contract. Per day penalties can be significant depending on the contract. We have delivered battery systems, charging systems and electric transit buses late in the past, and have incurred substantial penalties with respect to certain of these late deliveries, which have reduced our revenue and margin. Although we actively manage our production schedule and our customers’ expectations, we may still fail to meet delivery deadlines and may incur penalties as a result. If we are unable to realize our production plans and deliver our battery systems and buses on time, our reputation, business, prospects, financial condition, and operating results could be adversely affected.
Our business could be adversely affected if utilities and state utility commissions do not, or are slow to, support transportation electrification efforts.
Fleet-wide adoption of electric vehicles will benefit from favorable electricity rate structures for transit authorities and other large fleet operators and investment in make-ready infrastructure for electric vehicle charging at scale by utilities. For example, pursuant to California Senate Bill 350: Clean Energy and Pollution Reduction Act, the California investor-owned utilities have submitted Integrated Resource Plans that detailed how each utility will meet its customers’ resource needs and reduce greenhouse gas emissions, including support for transportation electrification. The California Public Utilities Commission approved the plans in May 2018, including Pacific Gas and Electric Company’s proposed investment in infrastructure and rebates and Southern California Edison Corporation’s proposed time-of-use rates for charging electric transit buses. In September 2018, the Public Service Enterprise Group in New Jersey outlined a number of initiatives, including providing funding for charging system installations, deploying make-ready electric infrastructure and making grants for electric school buses. The New Jersey Board of Public Utilities will now evaluate the filing. In addition, utility commissions in several states are also evaluating the needs and benefits of transportation electrification, including the transit bus sector.
Our customers expect to pay lower electricity costs and generally look to the utilities to invest in infrastructure upgrades that will support commercial vehicle electrification plans. Therefore, efforts on the part of utility companies and state utility commissions to develop an appropriate rate designed to ensure that electricity as a fuel is competitive with fossil fuels will improve the total cost of ownership benefits for our transit customers and vehicle fleet owners, and enhance the attractiveness of our other products and offerings. Similarly, investments that utilities make to upgrade the infrastructure necessary to support additional load on the electrical grid will save our customers from potentially having to make their own investments. However, if utilities and utility commissions do not make the necessary investments to support commercial vehicle electrification and develop the appropriate, cost-competitive electricity rates, or delay such efforts, the market for battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses, and related technologies may not develop as we expect or may develop more slowly than we expect, and our business, prospects, financial condition, and operating results could be adversely affected.
Our annual revenue has in the past depended, and will likely continue to depend, on a small number of customers that fluctuate from year to year, and failure to add new customers or expand sales to our existing customers could have an adverse effect on our operating results for a particular period.
Because the majority of our historical and current customers are public transit authorities that do not procure new vehicle fleets every year, the composition of customers that account for a significant portion of our revenue is likely to vary from year to year based on which customers have accepted delivery of large fleet orders with us during the applicable period. For example, two customers accounted for approximately 33% of our total revenue for the year ended December 31, 2022. Moreover, because public transit authorities tend to procure new vehicles in large batch orders, our revenue in any given quarter may be highly dependent on a single customer. For example, in the third and fourth quarter of 2022, approximately 45% and 67%, respectively, of electric transit buses were delivered to a single customer, Miami-Dade County. In the second quarter of 2020, approximately 50% of the electric transit buses we delivered were delivered to a single customer, the Port Authority of New York and New Jersey and in the fourth quarter of 2020, approximately 40% of the buses we delivered were delivered to a single customer, the City of Edmonton. We believe that we will continue to depend upon a relatively small number of customers for a significant portion of our revenue in any given period for the foreseeable future because we have only recently begun to deliver our buses and other products at a larger scale and we have a lengthy sales cycle and on-ramp for new customers. Our failure to diversify our customer base by adding new customers or expanding sales to our existing Proterra Transit customers and our failure to add new customers and expand sales to existing customers in our Proterra Powered and Proterra Energy businesses outside of the transit industry could therefore have an adverse effect on our operating results for a particular period.
Our industry and its technology are rapidly evolving and may be subject to unforeseen changes. Developments in alternative technologies and powertrains or improvements in the internal combustion
engine may adversely affect the demand for our electric transit buses and our electric battery solutions for commercial vehicles.
The electric vehicle industry, and the electric commercial vehicle industry in particular, is relatively new and has experienced substantial change in the last several years. As more companies invest in electric vehicle and autonomous vehicle technology and alternative modes of transportation, we may be unable to keep up with technology advancements and, as a result, our competitiveness may suffer. As technologies change, we plan to spend significant resources in ongoing research and development, and to upgrade or adapt our products and services, and introduce new products and services in order to continue to provide battery systems, electrification and charging solutions, fleet and energy management software for electric transit buses, and related technologies with the latest technology, in particular battery technology. Our research and development efforts may not be sufficient or could involve substantial costs and delays and lower our return on investment for our technologies. For example, we invested substantial resources into developing a charging system solution in 2018 and then replaced that solution by entering into a new contract for supply of charging systems a few years later. Delays or missed opportunities to adopt new technologies could adversely affect our business, prospects, financial condition, and operating results.
In addition, we may not be able to compete effectively with other alternative fuel vehicles and integrate the latest technology, which may include autonomous vehicle technology, into our battery systems, electrification and charging solutions, fleet and energy management systems, and related technologies. Even if we are able to keep pace with changes in technology and develop new products and services, we are subject to the risk that our prior models, products, services and designs will become obsolete more quickly than expected, resulting in unused inventory and potentially reducing our return on investment, or become increasingly difficult to service or provide replacement parts at competitive prices. For example, we incurred $0.8 million, $1.9 million and $3.0 million in inventory write-offs in 2022, 2021 and 2020, respectively, as the result of unused raw materials or adopting new technologies. Additionally, given the long sales cycle of each of our products and services, customers may delay purchases and modify or cancel existing orders in anticipation of the release of new models and technology. Moreover, developments in alternative technologies, such as advanced diesel, ethanol, fuel cells, or compressed natural gas, or improvements in the fuel economy of the internal combustion engine, may adversely affect our business and prospects in ways we do not currently anticipate. Any developments with respect to these technologies, in particular fuel cell technologies and related chemical research, or the perception that they may occur, may prompt us to invest heavily in additional research to compete effectively with these advances, which research and development may not be effective. Any failure by us to successfully react to changes in existing technologies could adversely affect our competitive position and growth prospects.
If we are unable to successfully manufacture and sell our battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses, and related technologies, our business could be adversely affected.
We have limited experience with manufacturing and selling battery systems, electrification and charging solutions, fleet and energy management software and electric transit buses, and related technologies to global commercial vehicle manufacturers and other types of manufacturers. As we develop partnerships with global commercial vehicle manufacturers to provide these products and other component parts to these partners and customers, we must introduce and implement manufacturing and quality control processes across our factories that are comparable to those of other Tier 1 suppliers in the automotive industry. We have identified areas for improvement as we scale and mature, such as ISO certification for our operations, that would allow us to meet quality standards required by companies such as Daimler and its subsidiaries. Furthermore, we must compete against more established battery designers, drivetrain designers, vehicle manufacturers, charging solution designers and component suppliers with greater resources and more experience in large scale manufacturing and deployment than we have. To compete effectively against these incumbent manufacturers and suppliers, we will have to devote substantial resources and effort to efficiently and effectively scale our manufacturing capabilities, implement new manufacturing and quality control processes, and enhance our existing processes. The implementation of a Tier 1 automotive supplier manufacturing operations inherently involves risks related to infrastructure and process development, quality control, and customer acceptance. If we fail to mature our manufacturing operations to the satisfaction of our customers, then our business, prospects, financial condition, and operating results could be adversely affected.
If we are unable to design, develop, market, and sell new products and services that address adjacent market opportunities, our business, prospects, and operating results may be adversely impacted.
We may not be able to successfully develop new products and services or develop a significantly broader customer base. For the past several years, we have focused our business on the development and sale of electric transit buses for the mass transit market. Our product line in the transit market is currently limited to the 40-foot and 35-foot ZX5 transit buses, and spare parts. We have recently expanded our offerings to include battery systems, electrification and charging solutions, and fleet and energy management software, and related technologies that are designed for broader application to other commercial vehicles.
In this regard, we have entered into development and supply agreements to develop and sell our battery systems, electrification and charging solutions and fleet and energy management software to other medium-duty and heavy-duty commercial vehicle manufacturers. Our business model offers end-to-end powertrain systems, energy system integrations when electric drivetrains are supplied by a third party, and battery system supply when integration and electric drivetrains are supplied by third parties to the end customer. Achieving success in these relatively new markets will require us to, among other things:
•enter into strategic agreements with leading manufacturers in these markets and maintain and grow these relationships;
•adapt our electric powertrain technology to meet the specifications of additional commercial vehicle categories;
•successfully compete with other manufacturers in the new markets;
•effectively and efficiently scale our manufacturing capabilities;
•effectively and efficiently grow and manage our supply chain;
•expand our sales and marketing capabilities;
•enter into service partnerships or expand our internal service and parts capabilities;
•expand our integration and engineering services to compete with other integrators and suppliers of high voltage systems, controls and drivetrains;
•expand our software and telematics platform to offer competitive solutions;
•develop technology solutions that are compatible with offerings of third-party providers;
•develop charging solutions, including software and telematics that are compatible with electric vehicle technology independent of manufacturer or supplier; and
•comply with changing regulations applicable to our products and services.
If we fail to adequately improve our products and services to compete effectively against our competitors, we may not be successful in expanding our customer base in the electric commercial vehicle market.
In addition, our failure to address additional market opportunities could harm our business, financial condition, operating results, and prospects. We may not be able to successfully design, develop, or test new products and services in order to effectively compete with our competitors in these new markets. Furthermore, there may be no demand by customers to purchase newly developed or improved products and services, there may be risks and unbudgeted costs associated with launching new products and services, and we may not be able to recoup our research and development costs, all of which could have an adverse effect on our business, prospects, financial condition, and operating results.
We may not be able to develop, maintain and grow strategic relationships in the Proterra Powered or Proterra Energy business, identify new strategic relationship opportunities, or form strategic relationships, in the future.
We expect that our ability to establish, maintain, and manage strategic relationships, such as development and supply agreements with customers that could have a significant impact on the success of our business. While we expect to increase the amount of revenue associated with Proterra Powered and Proterra Energy, there can be no assurance that we will be able to identify or secure suitable and scalable business relationship opportunities in the future or that our competitors will not capitalize on such opportunities before we do. Moreover, identifying such opportunities could demand substantial management time and resources, and may involve significant costs and uncertainties.
Additionally, we cannot guarantee that the companies with which we have developed or will develop strategic relationships will continue to devote the resources necessary to promote mutually beneficial business relationships and grow our business. Our current arrangements are not exclusive, and some of our strategic partners offer competing products. As a result of these factors, many of the companies with which we have development and supply agreements may choose to develop alternative products in addition to or in lieu of our solutions, either on their own or in collaboration with others, including our competitors. If we are unsuccessful in establishing or maintaining our relationships with key strategic partners, our overall growth could be impaired, and our business, prospects, financial condition, and operating results could be adversely affected.
Lack of long-term customer contracts, uncertainty regarding customer option exercises, and customer suspension or termination of contracts may have adverse effects on our business.
Proterra Transit relies heavily on sales to public and other transit authorities, which, consistent with general industry practice, do not make long-term purchase commitments with transit vendors. Most transit authorities usually undertake significant procurement of new transit buses once every few years and typically acquire a relatively small percentage of their fleet each time. Often, the terms of our procurements allow customers, without notice or penalty, to suspend or terminate their relationship with us at any time and for any reason. For example, one of our customers previously made an award to us for buses in 2017, but due in part to improvements in electric vehicle technology and the release of new bus models, withdrew the award in 2018 in favor of considering a new request for proposal process. Some customers have also elected to purchase fuel cell vehicles for their transit fleet. Even if customers continue their relationship with us, they may not purchase the same volume of products as in the past or they may not pay the same price for those products. This may also be true with respect to Proterra Powered, where customers may have long-term contracts, but are not subject to fixed quantity order requirements such that final orders may be below our revenue expectations or estimates.
Further, many transit authority contracts include options to purchase additional electric transit buses in the future, and while a portion of future orders may be represented by options, customers may not end up exercising these options. Although options represent a significant source of potential orders for us, we do not have an extensive history of fulfilling orders based on our customer option agreements. Even if we had a history of significant option exercises by customers, customers may not continue to exercise such options at the same rate or at all in the future. Any loss of customers or decrease in the number of electric transit buses or battery systems purchased under a contract could have an adverse effect on our business, prospects, financial condition, and operating results.
We are competing for the business of both small and large transit agencies, which place different demands on our business, and if we do not build an organization that can serve both types of transit customers, by scaling our internal resources to meet varying customer needs, our business, prospects, financial condition and operating results may be harmed.
Proterra Transit has competed for, and may in the future compete for, the business of larger transit agencies that maintain fleets of several hundred to thousands of vehicles, including Los Angeles, Miami Dade County and Chicago. This size of customer places significant demands on our business because they have large, specialized groups of professionals focused on different requirements or systems related to transit bus procurement and rigorous inspections with multiple levels of review to assure each bus meets their specifications, which may be driven by conformity with other vehicles in the fleet, large long-term supply contracts, such as for tires and other
wear items, and operating contracts with maintenance and operations teams. Serving these customers requires significant investment in customer relationship managers and service professionals to support the levels of design, review, change orders, inspection, and commissioning and delivery of the electric transit buses. Similarly, servicing our Proterra Powered customers requires significant investments in customer relationship managers and other professionals as each customer requires different levels of battery integration support and service.
We also compete for the business of smaller transit agencies. Although smaller transit agencies often have less complicated procurement processes than larger transit agencies, serving these smaller agencies requires processing small order sizes while still catering to the specific vehicle configurations for each customer. If we continue to serve both large and small transit agency customers, we will need to effectively and efficiently scale our internal resources to meet varying customer needs. Our failure to do so could have an adverse effect on our business, prospects, financial condition, and operating results.
Our business is subject to substantial regulations, which are evolving, and unfavorable changes or failure by us to comply with these regulations could have an adverse effect on our business.
The majority of our current transit customers are government entities and we are subject to many local, state, and federal laws that add significant compliance costs to our operations. In addition, local, state, and federal regulations may conflict, making it difficult to build one vehicle that satisfies all requirements in all jurisdictions. Moreover, competitive bidding rules for government contracts add additional layers of complexity and require compliance with federal and state conflict of interest rules and rules governing our choice of suppliers and components.
Our electric transit buses and component products must comply with the National Traffic and Motor Vehicle Safety Act of 1966, as amended (“NTMVSA”), and regulations promulgated thereunder, which are administered by the National Highway Traffic Safety Administration (“NHTSA”). NTMVSA requires vehicle and equipment manufacturers to provide notice of safety defects to NHTSA and initiate a recall process within five days of such a determination by a manufacturer. NHTSA also administers reporting requirements from vehicle manufacturers under the Transportation Recall Enhancement, Accountability and Documentation Act of 2000 (the “TREAD Act”). We have ongoing reporting requirements under the TREAD Act and in the past have failed to timely report under the TREAD Act. NHTSA may also require a manufacturer to recall and repair vehicles that contain safety defects or that are not compliant with FMVSS or other certification requirements for vehicles. Sales into foreign countries may be subject to similar regulations. We cannot assure you that violations of these laws and regulations will not occur in the future or have not occurred in the past as a result of human error, accidents, equipment failure, manufacturing or design defects, or other causes. It is possible that our reporting for historical periods for which we failed to timely report may reveal instances where we should have taken actions required by law but failed to do so. For example, we became subject to certain early warning reporting obligations under the TREAD Act in 2018. Our ongoing reporting obligations require us to provide certain early warning data to help identify potential safety-related defects, including certain safety data dating back ten years. While we have filed reports for current periods, we are currently not in full compliance with these early warning reporting requirements for prior periods. As we work to remediate our non-compliance, we may be subject to retrospective safety recall notices on our electric transit buses. Recalls of our electric transit buses or components, whether initiated by us, NHTSA or another authority, or penalties for regulatory compliance failures could have a material adverse effect on our reputation, business and operating results and be used by our competitors to our disadvantage.
Furthermore, if we choose to expand internationally, we would likely face additional international requirements that may not be compatible with regulations that govern our business in the United States. For example, in the United States, we developed our supply chain to ensure that we comply with Buy America regulations, which govern manufactured products and rolling stock, including transit bus, procurements that are paid for, in part, with funds administered by the FTA. Buy America regulations currently require that 70% of our vehicle components by cost be manufactured in the United States, and the Made in America Office opened under the Biden-Harris administration has proposed rules which may raise this requirement further. Buy America regulations have the effect of rendering the cost of our supply chain more expensive when compared with our competitors. As we began selling buses to airports, we had to modify our operations to comply with the Buy American requirements under the FAA rules, which differ from the Buy America requirements under the FTA rules. In June 2018, we received our first order from a Canadian transit authority, and as a result, we need to comply with Canadian Content requirements, which will require sourcing components from Canadian suppliers or assembly of
components in Canada. These regulations may increase the costs of doing business and add operational challenges.
In addition, there is no assurance that the current Buy America, Buy American, or Canadian Content requirements will not change or become stricter or that we will continue to be able to meet those requirements in the future. Our competitors have lobbied extensively to alter Buy America regulations to effectively prohibit our use of cylindrical battery cells produced outside of the United States for which there currently is no source of domestic supply available to us. Lack of domestic supply of cylindrical battery cells may also make our product less competitive and less desirable to customers that demand product that meets the domestic content requirements to achieve tariff-free status under the United States-Mexico-Canada trade agreement which entered into force on July 1, 2020.
Also, our ability to meet domestic content requirements is, in part, dependent on hundreds of suppliers. If any of these suppliers change the source of the components or subcomponents comprising their products, they could potentially prevent us from meeting domestic content requirements and negatively impact our business. Conversely, if domestic content requirements become less stringent in the future, foreign competitors without significant U.S. operations may be able to enter the U.S. market more easily and gain market share. Thus, any change to domestic content regulations could have an adverse effect on our business, prospects, financial condition, and operating results.
Delays in FTA mandated Model Bus Testing Program, or failure to successfully complete federally mandated testing, could adversely impact our business.
The FTA mandates that new transit bus models must undergo testing at its testing facility in Altoona, Pennsylvania and meet certain performance standards set by the FTA’s Model Bus Testing Program, known as “Altoona Testing,” in order to be eligible to receive federal funding. There is only one facility approved for testing by the FTA and in the past, we have experienced delays of several months before receiving regulatory approval to test our buses at Altoona, as well as delays in the actual testing at Altoona. The COVID-19 pandemic resulted in a shut-down of the Altoona facility in 2020 and there can be no assurances that the facility will not be shut down again due to the COVID-19 pandemic or otherwise. We may in the future choose to undergo testing or be required to do so.
When available, Altoona Testing is designed to promote production of better transit vehicles and components and to ensure that transit customers purchase vehicles that can withstand the rigors of transit service. Our 40-foot and 35-foot electric transit buses, including the ZX5 with DuoPower drivetrain, have satisfactorily completed Altoona Testing, but for each material change that we make to our transit bus platform, we must undergo a new round of testing. We have in the past and may in the future experience failures of components of our transit bus during Altoona Testing, which may prolong the test process, and cause us to be required to redesign components on the test bus and restart the testing process. Testing is available to vendors on a first-come, first-served basis. We cannot receive payment from customers relying on federal funds unless the applicable bus platform has satisfactorily completed Altoona Testing, and thus testing delays could have an adverse effect on our business, prospects, financial condition, and operating results. We have in the past and may in the future experience delays in Altoona Testing availability, including as a result of the COVID-19 pandemic, other pandemics, or other unforeseen events. In the past, a delay in receiving a required Altoona test report resulted in late delivery of buses to a customer and caused us to incur monetary penalties, delayed acceptance and delayed revenue recognition and customer payments. Moreover, there can be no assurance that the current Altoona Testing requirements will not change or become more onerous or that our future bus models will pass Altoona Testing. For instance, in 2016, the Model Bus Testing Program regulations changed to require a pass/fail test result. If we cannot produce electric transit buses that pass Altoona Testing, we would not be able to continue to sell buses to customers in the United States that rely on federal funds for their procurements, which would have a material and adverse effect on our business, prospects, financial condition, and operating results.
Failure to comply with the Disadvantaged Business Enterprise (“DBE”) program requirements or our failure to have our DBE goals approved by the FTA could adversely impact our transit business.
The FTA requires transit vehicle manufacturers that bid on federally-assisted rolling stock procurements to submit annual goals to support qualified DBEs (as defined in the DBE program regulations), and to certify that
they have complied with the requirements of the DBE program established by the U.S. Department of Transportation, which aims to increase the participation of DBEs in state and local procurements. Companies are certified as DBE if they are for-profit small businesses majority-owned by socially and economically disadvantaged individuals. The FTA reviews and approves transit vehicle manufacturers’ DBE goals for the upcoming year and maintains a certified list of transit vehicle manufacturers that are eligible to bid on federally funded vehicle procurements based on their goals to contract with DBEs and good faith implementation of those goals. Our failure to comply with the DBE program requirements or a delay in having our DBE goals approved by the FTA could result in our ineligibility to bid on federally funded transit vehicle procurements, which could have an adverse effect on our business, prospects, financial condition, and operating results.
Our business and prospects depend significantly on our ability to build our brand. We may not succeed in continuing to establish, maintain, and strengthen our brand, and our brand and reputation could be harmed by negative publicity regarding our company or products.
Our business and prospects are heavily dependent on our ability to develop, maintain, and strengthen our brand. Promoting and positioning our brand will depend significantly on our ability to provide high quality battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, and we have limited experience in these areas, particularly with respect to products and services that are not used in electric transit buses. In addition, we expect that our ability to develop, maintain, and strengthen our brand will also depend heavily on the success of our branding efforts. To promote our brand, we need to incur increased expenses, including product demonstrations and attending trade conferences. Brand promotion activities may not yield increased revenue, and even if they do, the increased revenue may not offset the expenses we incur in building and maintaining our brand and reputation. If we fail to promote and maintain our brand successfully or to maintain loyalty among our customers, or if we incur substantial expenses in an unsuccessful attempt to promote and maintain our brand, we may fail to attract new customers and partners, or retain our existing customers and partners and our business and financial condition may be adversely affected.
Moreover, any negative publicity relating to our employees, current or future partners, original equipment manufacturers deploying our battery or powertrain technology in their electric transit buses, partners or customers who use our high-voltage systems or software and telematics platforms, or others associated with these parties may also tarnish our own reputation simply by association and may reduce the value of our brand. Additionally, if safety or other incidents or product defects occur or are perceived to have occurred, whether or not such incidents or defects are our fault, we could be subject to adverse publicity, which could be particularly harmful to our business given our limited operating history. Given the popularity of social media, any negative publicity about our products or their safety, whether true or not, could quickly proliferate and harm customer and community perceptions and confidence in our brand. For example, in 2021, we were the subject of negative publicity arising out of the appearance of cracks in the composite bus body architecture, potential early retirement of some of our first generation transit buses and negative political commentary. Public transit agencies and OEMs are particularly sensitive to concerns and perceptions of the passenger and community constituencies they serve. If the passengers in our electric transit buses or people in communities where electric transit buses using our technology are deployed form a negative opinion of our electric transit buses or battery systems or charging solutions, our current and potential customers might not choose our products, and strategic partners in other markets may not adopt our battery systems or electric powertrain technology or charging solutions. Other businesses, including our competitors, and organized labor, may also be incentivized to fund negative campaigns against our company to damage our brand and reputation to further their own purposes. Future customers of our products and services may have similar sensitivities and may be subject to similar public opinion and perception risks. Damage to our brand and reputation may result in reduced demand for our products and increased risk of losing market share to our competitors. Any efforts to restore the value of our brand and rebuild our reputation may be costly and may not be successful, and our inability to develop and maintain a strong brand could have an adverse effect on our business, prospects, financial condition, and operating results.
The use of lithium-ion cells may become disfavored as a result of the availability, or perceived superiority of, other types of batteries or yet undeveloped or unknown technologies.
The battery packs that we currently produce make use of lithium-ion cells, which we believe currently represent the industry standard for battery technology for electric vehicles. It is possible, however, that other types of batteries or yet undeveloped or unknown technologies may become favored in the future, such as lithium iron
phosphate (“LFP”) batteries. LFP batteries currently have a wide range of applications, including in electric vehicle applications, and are perceived by many as offering cost-effective performance as compared to lithium-ion cells. The cost-effectiveness of LFPs is due, in part, to substantial investments in this technology development and manufacturing capability in China. While we believe that our products and services based on the lithium-ion cells that we have chosen to offer our customers present advantages with respect to ease of integration with their products and services and underlying performance, it is possible that these customers and partners may deem LFP-based technology, or other technologies, as sufficient or superior for their purposes, and may demand that we shift to LFP-based technology or decide to partner with other service providers who employ such technologies. In addition, it is possible that the performance, safety features or characteristics, reliability or cost-effectiveness of LFP batteries, or another form of battery, could improve in the future such that our current lithium-ion cell based offerings would become, or be perceived as, inferior or obsolete. In addition, it is possible that new forms of batteries or electrification technologies, such as solid state batteries, could emerge as a more cost effective or safer alternative to the batteries we currently offer. In the event that LFP or a new form of battery emerges or is deemed to exhibit better performance, operate at lower cost or exhibit better safety features, we could be compelled to attempt to integrate those new types of batteries into our platform, which may not be possible or feasible at a price that would be attractive to our customers or potential partners. Any developments with respect to LFP or new battery technology, or new electrification technologies that are based on unforeseen developments in fuel cell technology, or the perception that they may occur, may prompt us to invest heavily in additional research to compete effectively with these advances, which research and development may not be effective. Any failure by us to successfully react to changes in existing technologies could adversely affect our competitive position and growth prospects.
Our business could be adversely affected from an accident or safety incident involving our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses or defects in the materials or workmanship of our composite bus bodies or other components.
An accident or safety incident involving one of our battery systems, electrification and charging solutions, fleet and energy management systems or electric transit buses could expose us to significant liability and a public perception that our electric transit buses and products are unsafe or unreliable. Our agreements with customers contain broad indemnification provisions, and in the event of a major accident, we could be subject to significant personal injury and property claims that could subject us to substantial liability. While we maintain liability insurance in amounts and of the type generally consistent with industry practice, the amount of such coverage may not be adequate to cover fully all claims, and we may be forced to bear substantial losses from an accident or safety incident. In addition, any accident or safety incident involving one of our buses, even if fully insured, could harm our reputation and result in a loss of future customer demand if it creates a public perception that our electric transit buses are unsafe or unreliable as compared to those offered by other transit bus manufacturers or other means of transportation. While we have not experienced significant accident or safety incidents involving our electric transit buses, we have experienced malfunctions, such as the overhead single blade charger thermal events and a bus fire related to low voltage wiring. Moreover, the public may be more sensitive to incidents involving transit buses and school buses, thereby compounding the effects of such incidents on the public and customer perception of our electric transit buses. As a result, any accident or safety incident involving our buses, or the buses of our competitors could materially and adversely affect our business, prospects, financial condition, and operating results.
Our work with government customers exposes us to unique risks inherent in government contracting.
We must comply with and are affected by laws and regulations relating to the award, administration, and performance of government contracts. Government contract laws and regulations affect how we do business with our customers and impose certain risks and costs on our business. A violation of specific laws and regulations by us, our employees, or others working on our behalf could harm our reputation and result in the imposition of fines and penalties, the termination of our contracts, suspension or debarment from bidding on or being awarded contracts, and civil or criminal investigations or proceedings.
Our performance under our contracts with government entities and our compliance with the terms of those contracts and applicable laws and regulations are subject to periodic audit, review, and investigation by various agencies of the government. If such an audit, review, or investigation uncovers a violation of a law or regulation or improper or illegal activities relating to our government contracts, we may be subject to civil or criminal penalties
or administrative sanctions, including the termination of contracts, forfeiture of profits, the triggering of price reduction clauses, withholding of payments, suspension of payments, fines, and suspension or debarment from contracting with government agencies. There is inherent uncertainty as to the outcome of any audit, review, or investigation. If we incur a material penalty or administrative sanction or otherwise suffer harm to our reputation, our business, prospects, financial condition, or operating results could be adversely affected.
Further, if a government regulatory authority were to initiate suspension or debarment proceedings against us as a result of a conviction or indictment for illegal activities, we may lose our ability to be awarded contracts in the future or receive renewals of existing contracts for a period of time. We could also suffer harm to our reputation if allegations of impropriety were made against us, which would impair our ability to win awards of contracts in the future or receive renewals of existing contracts. Inability to be awarded contracts in the future or receive renewal of existing contacts could have an adverse effect on our business, prospects, financial condition, and operating results.
A portion of our business is dependent upon U.S. government contracts and grants, which are highly regulated and subject to oversight audits by U.S. government representatives and subject to cancellations. Such audits could result in adverse findings and negatively impact our business.
Our U.S. government business is subject to specific procurement regulations with numerous compliance requirements. These requirements, although customary in government contracting in the United States, increase our performance and compliance costs. These costs may increase in the future, thereby reducing our margins, which could have an adverse effect on our financial condition. Failure to comply with these regulations or other compliance requirements could lead to suspension or debarment from U.S. government contracting or subcontracting for a period. Among the causes for debarment are violations of various laws or policies, including those related to procurement integrity, export control, U.S. government security regulations, employment practices, protection of criminal justice data, protection of the environment, accuracy of records, proper recording of costs, foreign corruption, Trade Agreements Act, Buy America Act, and the False Claims Act.
Generally, in the United States, government contracts and grants are subject to oversight audits by government representatives. For example, in December 2020, the FTA released an audit of our and other manufacturers compliance with Buy America requirements. Such audits could result in adjustments to our contracts. For contracts covered by the Cost Accounting Standards, any costs found to be improperly allocated to a specific contract may not be allowed, and such costs already reimbursed may have to be refunded. Future audits and adjustments, if required, may materially reduce our revenues or profits upon completion and final negotiation of audits. Negative audit findings could also result in investigations, termination of a contract or grant, forfeiture of profits or reimbursements, suspension of payments, fines and suspension or prohibition from doing business with the U.S. government. All contracts with the U.S. government can be terminated for convenience by the government at any time.
In addition, contacts with government officials and participation in political activities are areas that are tightly controlled by federal, state, local and international laws. Failure to comply with these laws could cost us opportunities to seek certain government sales opportunities or even result in fines, prosecution, or debarment.
We may not be able to obtain, or comply with terms and conditions for, government grants, loans, and other incentives for which we have applied and may apply for in the future, which may limit our opportunities to expand our business.
We have in the past applied for and received state grants and tax incentives designed to promote the manufacturing of electric vehicles and related technologies, including charging solutions. In April 2015, the California Energy Commission awarded us $3.0 million based on our investment of approximately $8.4 million in our manufacturing facilities in California through December 31, 2018. In April 2017, California’s Office of Business and Economic Development entered into a California Competes Tax Credit Allocation Agreement with us for an award of a California Competes Tax Credit in the amount of $7.5 million if certain conditions in that agreement are met in the prescribed time periods. In April 2019, the California Energy Commission awarded us a $1.8 million grant based on our expected investment of approximately $4.3 million in our manufacturing facility in City of Industry, California.
We anticipate that in the future there will be new opportunities for us to apply for grants, loans, and other federal and state incentives. Our ability to obtain funds or incentives from government sources is subject to the availability of funds under applicable government programs and approval of our applications to participate in such programs. The application process for these funds and other incentives is and will remain highly competitive. We may not be successful in obtaining any of these additional grants, loans, and other incentives. We have in the past failed and may also in the future fail to comply with the conditions of these incentives, which could cause us to lose funding or negotiate with governmental entities to revise such conditions. For example, we received a grant in South Carolina in 2010 that was subject to certain performance criteria, including a condition that we create no fewer than 400 new full- time jobs. We were unable to meet the original deadline but negotiated with the South Carolina Coordinating Council for Economic Development (the “Council”) for an extension on the date of job creation and we have since fulfilled the revised condition to the Council’s satisfaction. Our estimates of job growth under our California Competes Tax Credit have also not come to fruition for certain fiscal years. We may be unable to find alternative sources of funding to meet our planned capital needs, in which case, our business, prospects, financial condition, and operating results could be adversely affected.
We may become subject to product liability claims, which could harm our financial condition and liquidity if we are not able to successfully defend or insure against such claims.
We provide indemnification to our customers who may be sued for product liability related to our electric transit buses and electric powertrain solutions, and we may otherwise be subject to product liability claims, including with respect to our charging solutions. The commercial vehicle market experiences significant product liability claims and we face inherent risk of exposure to claims in the event our electric transit buses or components do not perform as expected. Commercial vehicles including public transit buses have been involved and may in the future be involved in crashes resulting in death or personal injury, and in some cases catastrophic crashes resulting in the death and injury to many passengers.
While we carry insurance for product liability, it is possible that our insurance coverage may not cover the full exposure on a product liability claim of significant magnitude. A successful product liability claim against us could require us to pay a substantial monetary award. A product liability claim could also generate substantial negative publicity about our products and business and could have an adverse effect on our brand, business, prospects, financial condition, and operating results.
Changes to U.S. trade policies, including new tariffs or the renegotiation or termination of existing trade agreements or treaties, may adversely affect our financial performance.
We currently manufacture our products in the United States, but may consider other international locations, including locations in Canada. Although many of our suppliers are in the United States, we rely on a number of suppliers in other countries for key components. We are subject to risks and uncertainties associated with changing economic, political, and other conditions in foreign countries where our vendors are located, such as increased import duties, tariffs, trade restrictions, and quotas or other government regulations, work stoppages, fluctuations of foreign currencies, natural disasters, political unrest, and customs delays. Unavailability or delay of imports from our foreign vendors would likely cause interruptions in our supply chain and could have an adverse effect on our business, prospects, financial condition, and operating results.
Moreover, the U.S. federal government may alter U.S. international trade policy and to renegotiate or terminate certain existing trade agreements and treaties with foreign governments. The U.S. federal government renegotiated the North American Free Trade Agreement, renamed the U.S.-Mexico-Canada Agreement, which was signed on November 30, 2018. The U.S. federal government’s potential decision to re-enter, withdraw or modify other existing trade agreements or treaties could adversely impact our business, customers, and suppliers by disrupting trade and commercial transactions and adversely affecting the U.S. economy.
In addition, the U.S. federal government has imposed, tariffs on certain foreign goods. For example, in 2018, the U.S. federal government imposed additional tariffs under Section 232 of the Trade Expansion Act of 1962, as amended, on many products including certain aluminum products imported into the United States, which may impact the commercial vehicle market and our supply chain. Moreover, these tariffs, as well as country-specific or product-specific exemptions, may also lead to retaliatory actions from foreign governments that could adversely affect our business. Certain foreign governments, including China and the European Union, have instituted or may
consider imposing additional tariffs on certain U.S. goods. Restrictions on trade with foreign countries, imposition of customs duties, or further modifications to U.S. international trade policy have the potential to disrupt our supply chain or the supply chains of our suppliers and to adversely impact our costs, customers, suppliers, and the economy, which could have an adverse effect on our business, prospects, financial condition, and operating results.
We are subject to various environmental and safety laws and regulations that could impose substantial costs upon us and negatively impact our ability to operate our manufacturing facilities if we fail in our efforts to abide by these laws and regulations.
As a manufacturer, producer and seller of battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, we are subject to numerous environmental, health, and safety laws and regulations in the United States, including laws relating to exposure to, use, handling, storage, and disposal of hazardous materials, and the building, testing and use of batteries and high-voltage systems, and other components, such as HVAC systems. Moreover, we may be subject to additional regulations as we expand our operations internationally. The costs of compliance, including assessing changes to our operations and notices required in our facilities and on our electric transit buses regarding potential hazards could be substantial. In addition, we may be required to manufacture product with alternative technologies and materials that require changes to our engineering, supply and product development programs that could result in significant cost and delays in product introduction. We also may not be successful in complying with such laws and regulations which could impact our ability to sell our products in certain locations, or result in substantial fines and penalties if our products in service are found to be non-compliant with certain laws and regulations. We also expect regulation of electric powertrains will increase over time, and result in increased compliance costs. For example, beginning in 2023, we will need to receive a zero emission powertrain certification in California. In addition, we have indemnified certain of our landlords for any hazardous waste that may be found on or about property that we lease. Furthermore, delays in achieving required certifications may prevent us from selling product in certain markets, and, any violations of applicable environmental and safety laws and regulations may result in substantial fines and penalties, remediation costs, third-party damages, a suspension or cessation of our sales of product or operations, and negative publicity that could harm our business, reputation, prospects, financial condition, and operating results.
Our future success depends on the continuing efforts of our key employees and on our ability to hire, retain, and motivate additional key employees and scale our workforce.
Our future success depends upon the continuing services of our key employees and on our ability to attract and retain members of our management team and other highly skilled employees, including battery and high voltage systems engineers, electric powertrain designers and engineers, vehicle systems and integration engineers, supply chain and quality control employees, sales personnel, service personnel, and software engineers and manufacturing talent. In our key areas of operations, including California, there is increasing competition for individuals with skill sets needed for our business, including specialized knowledge of batteries, electric vehicles, software engineering, and manufacturing engineering and quality control. This competition affects both our ability to retain key employees and hire new ones. Moreover, none of our key employees has an employment agreement for a specific term and any of our employees may terminate his or her employment with us at any time. Our continued success depends upon our continued ability to retain current employees and hire new employees in a timely manner, especially to support our expansion plans and to continue to ramp up our suite of offerings related to commercial vehicle electrification. For example, we started production at our Powered 1 factory in Greer, South Carolina in January 2023, and have needed and will continue to need to hire many people to achieve maximum production there. We are also adding additional production shifts at existing facilities. If we cannot find sufficiently trained staff in a timely manner, our launch of production at this facility could be delayed and adversely impact our business. Additionally, we compete for talent with both large and established companies that have far greater financial resources than we do and start-ups and emerging companies that may promise more attractive growth opportunities.
Furthermore, the reduction in workforce that we implemented in the first quarter of 2023 may yield unintended consequences and costs, such as the loss of institutional knowledge and expertise, employee attrition beyond our intended reduction in force, a reduction in morale among our remaining employees, greater-than-anticipated costs incurred in connection with implementing the restructuring, and the risk that we may not achieve the benefits from
the restructuring to the extent or as quickly as we anticipate, all of which may have a material adverse effect on our business, results of operations or financial condition. These restructuring initiatives could place substantial demands on our management and employees, which could lead to the diversion of our management’s and employees’ attention from other business priorities. In addition, we may discover that the workforce reduction and other restructuring efforts will make it difficult for us to pursue new opportunities and initiatives and require us to hire qualified replacement personnel, which may require us to incur additional and unanticipated costs and expenses.
In addition, new employees often require significant training and, in many cases, take significant time before they achieve full productivity. As a result, we may incur significant costs to attract and retain new employees, including significant expenditures related to salaries and benefits and compensation expenses related to equity awards, and we may lose new employees to our competitors or other companies before we realize the benefit of our investment in recruiting and training them. Moreover, new employees may not be or become as productive as we expect, as we may face challenges in adequately or appropriately integrating them into our workforce and culture. Difficulties in retaining current employees or recruiting new ones could have an adverse effect on our business, prospects, financial condition, and operating results.
Our businesses rely heavily on our specialized sales personnel and technical sales support to market and sell our products. If we are unable to effectively hire, train, manage, and retain our sales personnel, our business may be adversely impacted.
The success of our businesses largely depends on our ability to hire, train, and manage our sales personnel who have experience with and connections to the public and other transit agencies and commercial vehicle OEMs that are our current and potential customers. Because we employ a small and specialized sales force, the loss of any member of our sales team or technical sales support professionals could weaken our sales expertise and our customer reach, and adversely affect our business, and we may not be able to find adequate replacements on a timely basis, or at all. Moreover, there are no assurances that we will be able to maintain a sufficient level of sales personnel to effectively meet our needs as our business continues to grow, particularly with respect to Proterra Powered and Proterra Energy.
Competition for sales personnel who are familiar with and trained to sell our products and services continues to be strong. We train our sales personnel to better understand our existing and new product technologies and how they can be positioned against our competitors’ products. We also train our sales personnel to be adept at working with long sales cycles characteristic of public agency customers and commercial vehicle manufacturers, as well as the special requirements attendant to each.
These initiatives are intended to improve the productivity of our sales personnel and our revenue and profitability. It takes time for the sales professionals to become productive following their hiring and training and there can be no assurance that sales representatives will reach adequate levels of productivity, or that we will not experience significant levels of attrition in the future. Measures we implement to improve the productivity may not be successful and may instead contribute to instability in our operations, departures from our sales and technical support organizations, or reduce our revenue, profitability, and harm our business.
If we are unable to obtain bid bonds, performance bonds, or letters of credit required by public transit agencies or other customers, our ability to obtain future projects could be negatively affected.
We have in the past been, and may in the future be, required to provide bid bonds or performance bonds to secure our performance under customer contracts or, in some cases, as a prerequisite to submitting a bid on a potential project. Our continued ability to obtain these bonds will depend primarily upon our capitalization, working capital, past performance, management expertise, reputation and certain external factors, including the overall capacity of the surety market. Surety companies consider these factors in relation to the amount of our awards and their underwriting standards, which may change from time to time. Surety companies also require that we collateralize a percentage of the bond with cash or other form of credit enhancement. With a decreasing number of insurance providers in that market, it may be difficult to find sureties who will continue to provide contract-required bonding on acceptable terms and conditions, or at all. Furthermore, events that affect surety markets generally may result in bonding becoming more difficult to obtain in the future or being available only at a significantly greater cost.
In addition, some of our Proterra Transit and Proterra Energy customers also require collateral guarantees in the form of letters of credit to secure performance or to fund possible damages in the event of default under our contracts with them. If we enter agreements that require the issuance of letters of credit, our liquidity could be negatively impacted. Our inability to obtain adequate bonding or letters of credit and, as a result, to bid or enter into agreements, could have an adverse effect on our business, prospects, financial condition, and operating results.
We may experience outages and disruptions of our services if we fail to maintain adequate security and supporting infrastructure as we scale our information technology systems.
As we grow our business, we expect to continue to invest in our existing information technology systems, including data centers, network services, data storage, and database technologies, and cybersecurity technologies both to assist us in our business and to better provide our fleet-scale, high-power charging solutions and software services to our customers. Creating the appropriate information technology support systems for our business is time intensive, expensive, and complex. Our implementation, maintenance, and improvement of these systems may create inefficiencies, operational failures and increased vulnerability to cyber-attacks. Moreover, there are inherent risks associated with developing, improving, and implementing new information technology systems, including the disruption of our current data management, procurement, manufacturing, execution, finance, supply chain, sales, and service processes. As we continue to grow our services that rely on collecting and analyzing customer telematics and charging data, our exposure to information technology risks will increase. These risks may affect our ability to manage our data and inventory, procure parts or supplies or manufacture, sell, deliver, and service electric transit buses, or achieve and maintain compliance with applicable regulations.
We also maintain information technology measures designed to protect us against system security risks, data breaches, and cyber-attacks. Cyber-attacks could include denial-of-service attacks impacting customer service availability and reliability, the exploitation of software vulnerabilities in internet facing applications, social engineering of system administrators (for example, tricking company employees into releasing control of their systems to a hacker), or the introduction of computer viruses or malware into our systems to steal confidential or proprietary data. In 2020, we were the victim of a successful social engineering attack that resulted in the diversion of significant funds we intended to pay a supplier to a fraudulent account. In the third quarter of 2021, human error also resulted in a server for our Valence platform being accessible to the public for a short period of time, allowing unauthorized access to telematics data and, resulting in the deletion of a limited amount of data used by employees and customers for report functionality. Cyber-attacks of increasing sophistication may be difficult to detect and could result in the theft of our funds, intellectual property and data. In addition, we are vulnerable to unintentional errors or malicious actions by persons who have authorized access to our systems but exceed the scope of their access rights, or unintentionally or intentionally alter parameters or otherwise interfere with the intended operations of our technology services. The steps we take to increase the reliability, integrity, and security of our systems as they scale may be expensive and may not prevent system failures or unintended vulnerabilities resulting from the increasing number of persons with access to our systems, complex interactions within our technology platform and the increasing number of connections with third-party partners’ and vendors’ technology. Operational errors or failures or successful cyber-attacks could compromise our proprietary information, the quality of our services, and our ability to perform for our customers, resulting in damage to our reputation, which could have an adverse effect on our business, prospects, financial condition, and operating results.In addition, these events could increase the risk of claims alleging that we do not comply with applicable laws and regulations, subjecting us to potential liability and regulatory penalties under privacy laws protecting personal information.
If we update our manufacturing equipment more quickly than expected, we may have to shorten the useful lives of any equipment to be retired as a result of any such update, and the resulting acceleration in our depreciation could negatively affect our financial results.
We have invested and expect to continue to invest significantly in what we believe is state-of-the-art tooling, machinery, and other manufacturing equipment for production of our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies. We depreciate the cost of such equipment and electric transit buses over their expected useful lives. However, manufacturing and commercial vehicle technology may evolve rapidly, and we may decide to update our manufacturing process with more advanced equipment or tooling. Moreover, as our engineering and manufacturing expertise and
efficiency increase, we may be able to manufacture our products using less of our installed equipment. The useful life of any equipment that would be retired early as a result would be shortened, causing the depreciation on such equipment to be accelerated, and our operating results could be negatively impacted.
Our business may be adversely affected by workforce disruptions.
Our production employees in our City of Industry facility are represented by a union and we are party to a collective bargaining agreement that will expire in 2023 as we exit the City of Industry facility and no longer employ the employees that constitute the bargaining unit. Our other employees are not represented by a union, though it is common throughout the commercial vehicle industry for employees to belong to a union, and if more of our employees decide to join or form a labor union, we may become party to additional collective bargaining agreements, which could result in higher employee costs, higher administrative and legal costs, and increased risk of work stoppages. It is also possible that a union seeking to organize our facilities may mount a corporate campaign, resulting in negative publicity or other actions that require attention by our management team and our employees. Negative publicity, work stoppages, or strikes by unions could have an adverse effect on our business, prospects, financial condition, and operating results.
Moreover, some of our suppliers and vendors, including freight companies, have workforces represented by unions and are subject to collective bargaining agreements. The failure of our suppliers and vendors to successfully negotiate collective bargaining agreements could result in disruptions to our supply chain, manufacturing, and sale of our electric transit buses. Such delays could have an adverse impact on our business, prospects, financial condition, or operating results.
We may acquire or invest in additional companies, or undertake other strategic transactions or other business relationships which may divert our management’s attention, result in additional dilution to our stockholders, consume resources that are necessary to sustain our business, and which we may not be able to integrate successfully.
In 2022, we made a strategic equity investment in a privately held entity that we expect to produce lithium iron phosphate (LFP) battery cells in the United States in the coming years to provide us with development opportunities for battery packs with another cell chemistry to address additional segments of the commercial vehicle market. We may never be able to capitalize on the opportunity that we anticipated with this investment, for a number of reasons including our own future strategic decisions or the entity’s failure, which may result in no return on our investment. Although we have not made any acquisitions to date, our business strategy in the future may include acquiring other complementary products, technologies, or businesses or making further investments in companies that the management team believes are important to our supply chain or other strategic business interests. We also may enter relationships with other businesses to expand our domestic and international operations and to create services networks to support our products, such as a joint venture or other strategic partnerships. An acquisition, investment, or other strategic transaction or business relationship may result in unforeseen operating difficulties and expenditures. We may encounter difficulties assimilating or integrating the businesses, technologies, products, services, personnel, or operations of the acquired companies particularly if the key personnel of the acquired companies choose not to work for us. Acquisitions or other strategic transactions may also disrupt our business, divert our resources, and require significant management attention that would otherwise be available for the development of our business. Moreover, the anticipated benefits of any acquisition, investment, or other strategic transaction or business relationship may not be realized or we may be exposed to unknown liabilities.
Negotiating these types of transactions can be time consuming, difficult, and expensive, and our ability to close these transactions may often be subject to approvals that are beyond our control. Consequently, these transactions, even if undertaken and announced, may not close. Even if we do successfully complete transactions, we may not ultimately strengthen our competitive position or achieve our goals, and any transactions we complete could be viewed negatively by our customers, securities analysts, and investors.
Any potential future international expansion will subject us to additional costs and risks that could harm our business, including unfavorable regulatory, political, tax, and labor conditions, and our potential future efforts to expand internationally may not be successful.
Should we choose to expand our business internationally in the future and establish business relationships with new international partners, we may be subject to legal, political, and regulatory requirements and social and economic conditions that may be very different from those affecting us domestically. For example, we have expanded our transit business into Canada. As we expanded into Canada, our electric transit buses were required to comply with Canadian Motor Vehicle Safety Standards, which differ from the FMVSS. Funding for transit bus procurement from certain provincial governments in Canada also requires compliance with Canadian Content requirements, which will require different supply chain partners than those that we rely on for our electric transit buses sold in the U.S. market and assembly of certain components or subcomponents in Canada. In addition, we are providing products and services to OEMs in Australia and Western Europe, and as we expand our Proterra Powered or Proterra Energy business internationally, or should we choose to further expand our Proterra Transit business outside the United States and Canada, we may face a number of risks associated with international business activities that may increase our costs, impact our ability to sell our electric transit buses, and require significant management attention. These risks include:
•conforming our products to various international regulatory and safety requirements as well as charging and other electric infrastructures;
•difficulty in establishing, staffing, and managing foreign operations and service networks;
•challenges in attracting international customers;
•preferences of foreign nations for domestically manufactured products;
•our ability to enforce our contractual rights;
•longer sales and collection cycles in some countries;
•weaker intellectual property protection in some countries;
•compliance with multiple, potentially conflicting and changing governmental laws, regulations and permitting processes, including environmental, product safety, banking, employment, and tax;
•compliance with U.S. and foreign anti-bribery laws including the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”), and the UK Bribery Act of 2010;
•currency exchange rate fluctuations;
•regional economic and political instability, including as a result of acts of war or terrorism in countries where we may operate;
•restrictions on repatriations of earnings;
•trade restrictions, customs regulations, tariffs, and price or exchange controls;
•increased competition from local providers of similar products;
•increased costs to establish and maintain effective controls at foreign locations; and
•overall higher costs of doing business internationally.
As a result of these risks, any potential future international expansion efforts that we may undertake may not be successful and may incur significant operational expenses. Our failure to manage these risks and challenges successfully could have an adverse effect on our business, prospects, financial condition, and operating results.
Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
We may be limited in the portion of net operating loss (“NOL”) carryforwards that we can use in the future to offset taxable income for U.S. federal and state income tax purposes. As of December 31, 2022, we had U.S. federal NOL carryforwards and state NOL carryforwards of approximately $729.5 million and $531.1 million, respectively, which if not utilized will begin to expire for federal and state tax purposes beginning in 2030 and 2023, respectively. Federal NOLs generated after December 31, 2017 have an indefinite carryover period, and federal NOLs generated after December 31, 2017 may be utilized to offset no more than 80% of taxable income annually. Realization of NOL carryforwards that expire beginning in 2030 and 2023, respectively, depends on future income, and there is a risk that these carryforwards could expire unused and be unavailable to offset future income tax liabilities, which could adversely affect our operating results.
In addition, under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income may be limited. While we have conducted a Section 382 study in the past, we may experience ownership changes in the future, including as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre-change NOL carry-forwards and other tax attributes to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us.
U.S. federal income tax reform could adversely affect us.
New legislation or regulations that could affect our tax burden could be enacted by any governmental authority. United States federal legislation affecting the tax laws was enacted in December 2017 (the “Tax Cuts and Jobs Act” or “TCJA”), March 2020 (the “Families First Coronavirus Response Act”), March 2020 (the “CARES Act”), December 2020 (“Consolidated Appropriations Act, 2021”) and August 2022 (the “Inflation Reduction Act” or “IRA”).
We continue to examine the impact the TCJA and CARES Act may have on our business. The TCJA is a far- reaching and complex revision to the U.S. federal income tax laws with disparate and, in some cases, countervailing impacts on different categories of taxpayers and industries, and will require subsequent rulemaking and interpretation in a number of areas. The long-term impact of the TCJA on the overall economy, the industries in which we operate and our and our partners’ businesses cannot be reliably predicted at this early stage of the new law’s implementation. For example, beginning in 2022, the TCJA eliminates the option to deduct research and development expenditures in the year they were incurred and instead requires taxpayers to capitalize and amortize these expenditures over five or fifteen years pursuant to Section 174 of the Internal Revenue Code. Although there is proposed legislation that would defer the capitalization requirement to later years, we have no assurance that the provision will be repealed or otherwise modified. There can be no assurance that the TCJA will not negatively impact our operating results, financial condition, and future business operations. The estimated impact of the TCJA is based on our management’s current knowledge and assumptions, following consultation with our tax advisors. Because of our valuation allowance in the United States, ongoing tax effects of the Act are not expected to materially change our effective tax rate in future periods.
In response to the COVID-19 pandemic, California’s Legislature passed Assembly Bill 85 (“A.B. 85”), which suspends the use of net operating losses for tax years beginning in 2020, 2021, and 2022 for taxpayers with taxable income of $1.0 million or more before an application of net operating loss. A.B. 85 includes an extended carryover period for the suspended net operating losses with an additional year carryforward for each year of suspension. A.B. 85 also limits the utilization of business incentive tax credits for taxable years 2020, 2021, and 2022, requiring that taxpayers can only claim a maximum of $5.0 million in tax credit on an aggregate basis. On February 9, 2022, Governor Gavin Newsom signed Senate Bill 113 (“SB 113”). SB 113 restores the use of California net operating losses and eliminates the $5 million annual business credit limit of A.B. 85 for tax years beginning on or after January 1, 2022.
On August 16, 2022, President Biden signed the IRA, which became effective beginning in 2023. The IRA includes implementation of a new alternative minimum tax, an excise tax on stock buybacks, other significant tax incentives for energy and climate initiatives and other provisions. These new incentives may increase competition.
We use our best judgment in attempting to quantify and reserve for these tax obligations. However, a challenge by a taxing authority, our ability to utilize tax benefits such as carryforwards or tax credits, or a deviation from other tax-related assumptions may cause actual financial results to deviate from previous estimates.
Our business is subject to the risk of earthquakes, fire, power outages, floods, and other catastrophic events and to interruption by man-made problems such as terrorism.
We maintain production facilities in Northern and Southern California and South Carolina. Any of our facilities may be harmed or rendered inoperable by disasters, including earthquakes, tornadoes, hurricanes, wildfires, floods, nuclear disasters, geopolitical events, acts of terrorism or other criminal activities, infectious disease outbreaks (such as COVID-19), and power outages. In the event of natural disaster or other catastrophic event, we may be unable to continue our operations and may endure production interruptions, reputational harm, delays in manufacturing, development and testing of our battery systems, electrification and charging solutions, fleet and energy management systems, electric transit buses, and related technologies, and loss of critical data, all of which could have an adverse effect on our business, prospects, financial condition, and operating results. Moreover, our corporate headquarters and one of our current battery production facilities are in the San Francisco Bay Area, and we have facilities in Los Angeles County, regions known for seismic activity and potentially subject to catastrophic fires. If our facilities are damaged by such natural disasters or catastrophic events, our repair or replacement would likely be costly and any such efforts would likely require substantial time that may affect our ability to produce and deliver our products. For example, in July 2015, we experienced a fire in our Greenville, South Carolina manufacturing facility and then-headquarters, in which substantially all of our computer equipment, furniture and fixtures, leasehold improvements, work in progress, raw material, and finished goods inventories were damaged or destroyed. While we were insured for our losses and resumed manufacturing shortly thereafter, the disruption temporarily impacted our business. Similarly, any future disruptions in our operations could negatively impact our business, prospects, financial condition, and operating results and harm our reputation. In addition, we may not carry enough insurance to compensate for the losses that may occur.
Risks Related to Regulation
Failure to comply with anti-corruption, anti-money laundering laws, and sanctions laws,import and export controls, including the FCPA and similar laws associated with our activities outside of the United States, could subject us to penalties and other adverse consequences.
We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the UK Bribery Act of 2010, U.S. and foreign laws relating to import and export controls, economic sanctions, including the laws and regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control, and may be subject to other anti-bribery, anti-money laundering, and sanctions laws in countries in which we conduct activities. We face significant risks if we fail to comply with the FCPA and other anti-corruption laws that prohibit companies and their employees and third-party intermediaries from promising, authorizing, offering, or providing, directly or indirectly, improper payments or benefits to foreign government officials, political parties, and private sector recipients for the purpose of obtaining or retaining business, directing business to any person, or securing any advantage. In many foreign countries, particularly in countries with developing economies, it may be a local custom that businesses engage in practices that are prohibited by the FCPA or other applicable laws and regulations. We may have direct or indirect interactions with officials and employees of government agencies or state- owned or affiliated entities and we can be held liable for the corrupt or other illegal activities of these third- party intermediaries, our employees, representatives, contractors, partners, and agents, even if we do not explicitly authorize such activities. We have implemented an anti-corruption compliance program but cannot assure you that all of our employees and agents, as well as those companies to which we outsource certain of our business operations, will not take actions in violation of our policies and applicable law, for which we may be ultimately held responsible.
Our products and solutions are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and the economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls, as well as similar laws in other countries in which we conduct business. Exports of our products, services, and technology must be made in compliance with these laws and regulations. In addition, these laws may restrict or prohibit altogether the sale or
supply of certain of our products, services, and technologies to certain governments, persons, entities, countries, and territories, including those that are the target of comprehensive sanctions, unless there are license exceptions that apply or specific licenses are obtained. Any future changes in export control, import, or economic sanctions laws and regulations may adversely impact our ability to sell our products, services, and technologies in certain markets or, in some cases, prevent the export or import of our products, services, and technologies to or from certain countries, governments, or persons altogether, which could adversely affect our business, results of operations, and growth prospects.
Any violation of the FCPA, other applicable anti-corruption laws, anti-money laundering, import and export controls, economic sanctions laws and other applicable laws could result in whistleblower complaints, adverse media coverage, investigations, loss of export privileges, or severe criminal or civil sanctions, which could have an adverse effect on our business, prospects, financial condition, and operating results. In addition, responding to any enforcement action may result in a significant diversion of management’s attention and resources, significant defense costs, and other professional fees.
The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain additional executive management and qualified board members.
We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”), the listing requirements of Nasdaq and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming, or costly, and increase demand on our systems and resources, particularly after we are no longer an emerging growth company. The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and operating results. Although we have already hired additional employees to comply with these requirements, we may need to hire more employees in the future or engage outside consultants, which would increase our costs and expenses.
In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs, and making some activities more time consuming. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve or otherwise change over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations, and standards (or changing interpretations of them), and this investment may result in increased selling, general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us, and our business may be adversely affected. We also expect that being a public company and the associated rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our board of directors, particularly to serve on our audit committee, compensation committee, and nominating and governance committee, and qualified executive officers.
As a result of disclosure of information in the filings required of a public company, our business and financial condition is more visible, which may result in threatened or actual litigation, including by competitors. If such claims are successful, our business and operating results could be adversely affected, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and adversely affect our business and operating results. In
addition, as a result of our disclosure obligations as a public company, we have reduced flexibility and are under pressure to focus on short-term results, which may adversely affect our ability to achieve long-term profitability.
Regulations related to “conflict minerals” may force us to incur additional expenses, may make our supply chain more complex and may result in damage to our reputation with customers.
Pursuant to the Dodd-Frank Act, the SEC has adopted requirements for companies that use certain minerals and metals, known as conflict minerals, in their products, whether or not these products are manufactured by third parties. These requirements require companies to perform due diligence, disclose, and report whether such minerals originate from the Democratic Republic of Congo and adjoining countries, or come from recycled or scrap sources. These requirements could adversely affect the sourcing, availability, and pricing of minerals used in the manufacture of heavy-duty electric vehicles, including our products. While these requirements continue to be subject to administrative uncertainty, we will incur additional costs to comply with the disclosure requirements, including costs related to determining the source of any of the relevant minerals and metals used in our products. Since our supply chain is complex, we may not be able to sufficiently verify the origins for these minerals and metals used in our products through the due diligence procedures that we implement, which may harm our reputation. In such event, we may also face difficulties in satisfying customers who require that all of the components of our products are certified as conflict mineral free.
Risks Related to our Intellectual Property
Failure to protect our intellectual property could adversely affect our business.
Our success depends in large part on our proprietary technology, software and data. We rely on various intellectual property rights, including patents, copyrights, trademarks, and trade secrets, as well as confidentiality provisions and contractual arrangements, and other forms of statutory protection to protect our proprietary rights. If we do not protect and enforce our intellectual property rights adequately and successfully, our competitive position may suffer, which could adversely affect our business, prospects, financial condition, and operating results.
Our pending patent or trademark applications may not be approved, or competitors or others may challenge the validity, enforceability, or scope of our patents, the scope of our copyrights, the registrability of our trademarks or the trade secret status of our proprietary information. There can be no assurance that additional patents will be issued or that any issued patents will provide significant protection for our intellectual property or for those portions of our proprietary technology and software that are the most key to our competitive positions in the marketplace. In addition, our patents, copyrights, trademarks, trade secrets, and other intellectual property rights may not provide us a significant competitive advantage. There is no assurance that the forms of intellectual property protection that we seek, including business decisions about when and where to file patents and when and how to maintain and protect copyrights, trade secrets, license and other contractual rights will be adequate to protect our business.
Moreover, recent amendments to developing jurisprudence regarding and current and possible future changes to intellectual property laws and regulations, including U.S. and foreign patent, copyright, trade secret and other statutory law, may affect our ability to protect and enforce our intellectual property rights and to protect our proprietary technology, software and data. In addition, the laws of some countries do not provide the same level of protection for our intellectual property as do the laws of the United States. As we expand our international activities, our exposure to unauthorized copying and use of our technology and proprietary information will likely increase. Despite our precautions, our intellectual property is vulnerable to unauthorized access and copying through employee or third-party error or actions, including malicious state or state-sponsored actors, theft, hacking, cybersecurity incidents, and other security breaches and incidents, and such incidents may be difficult to detect or unknown for a significant period of time. It is possible for third parties to infringe upon or misappropriate our intellectual property, to copy or reverse engineer our bus and battery pack designs, and to use information that we regard as proprietary to create products and services that compete with ours. Effective intellectual property protection may not be available to us in every country in which we may sell our electric transit buses and related or other products and services. In addition, many countries limit the enforceability of patents against certain third parties, including government agencies or government contractors, or make patents subject to
compulsory licenses to third parties under certain circumstances. In these countries, patents may provide limited or no benefit.
Intellectual property laws, procedures, and restrictions provide only limited protection and any of our intellectual property rights may be challenged, invalidated, circumvented, infringed, or misappropriated. Further, the laws of certain countries do not protect proprietary rights to the same extent as the laws of the United States, and, therefore, in certain jurisdictions, we may be unable to protect our proprietary technology.
We enter into confidentiality and invention assignment or intellectual property ownership agreements with our employees and contractors and enter into confidentiality agreements with other third parties. We cannot ensure that these agreements, or all the terms thereof, will be enforceable or compliant with applicable law, or otherwise effective in controlling access to, use of, reverse engineering, and distribution of our proprietary information or in effectively securing exclusive ownership of intellectual property developed by our current or former employees and contractors. Further, these agreements with our employees, contractors, and other parties may not prevent other parties from independently developing technologies, products and services that are substantially equivalent or superior to our technologies, products and services.
We may need to spend significant resources securing and monitoring our intellectual property rights, and we may or may not be able to detect infringement by third parties. Our competitive position may be adversely impacted if we cannot detect infringement or enforce our intellectual property rights quickly or at all. In some circumstances, we may choose not to pursue enforcement because an infringer has a dominant intellectual property position, because of uncertainty relating to the scope of our intellectual property or the outcome of an enforcement action, or for other business reasons. In addition, competitors might avoid infringement by designing around our intellectual property rights or by developing non-infringing competing technologies. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming, and distracting to management and our development teams and could result in the impairment or loss of portions of our intellectual property. Further, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims attacking the scope, validity, and enforceability of our intellectual property rights, or with counterclaims and countersuits asserting infringement by us of third-party intellectual property rights. Our failure to secure, protect, and enforce our intellectual property rights could adversely affect our brand and our business, any of which could have an adverse effect on our business, prospects, financial condition, and operating results.
We may be subject to intellectual property rights claims or other litigation by third parties, which could be costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.
Third parties may assert claims of infringement of intellectual property rights or violation of other statutory, license or contractual rights in technology, software or data against us or against our customers for which we may be liable or have an indemnification obligation. Any such claim by a third party, even if without merit, could cause us to incur substantial costs defending against such claim and could distract our management and our development teams from our business.
Although third parties may offer a license to their technology, software or data, the terms of any offered license may not be acceptable and the failure to obtain a license or the costs associated with any license could cause our business, prospects, financial condition, and operating results to be adversely affected. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology, software or data licensed to us. Alternatively, we may be required to develop non-infringing technology, software or data which could require significant effort and expense and ultimately may not be successful. Furthermore, a successful claimant could secure a judgment or we may agree to a settlement that prevents us from selling certain products or performing certain services or that requires us to pay substantial damages, including treble damages if we are found to have willfully infringed such claimant’s patents, copyrights, trade secrets or other statutory rights, royalties or other fees. Any of these events could have an adverse effect on our business, prospects, financial condition, and operating results.
Adverse litigation judgments or settlements resulting from legal proceedings in which we may be involved could expose us to monetary damages or limit our ability to operate our business.
We have in the past and may in the future become involved in private actions, collective actions, investigations, and various other legal proceedings by customers, employees, suppliers, competitors, government agencies, or others. The results of any such litigation, investigations, and other legal proceedings are inherently unpredictable and expensive. Any claims against us, whether meritorious or not, could be time consuming, result in costly litigation, damage our reputation, require significant management time, and divert significant resources. If any of these legal proceedings were to be determined adversely to us, or we were to enter into a settlement arrangement, we could be exposed to monetary damages or limits on our ability to operate our business, which could have an adverse effect on our business, financial condition, and operating results.
Risks Related to our Common Stock
The price of our common stock has been and may continue to be volatile.
From January 3, 2022 through December 30, 2022, our common stock price has ranged from a low of $3.51 to a high of $10.90. For the period from January 1, 2023 through March 16, 2023, our common stock price has ranged from a low of $1.165 to a high of $5.62. As a result of this volatility, investors in our common stock may not be able to sell their shares at or above the prices they paid. Further, as a result of this volatility it may be difficult for us to attract new investments, including additional offerings of our securities, on terms we consider reasonable, or at all. The price of our common stock has fluctuated and may fluctuate in the future due to a variety of factors, including:
•changes in the industries in which we and our customers operate;
•variations in our operating performance and the performance of our competitors in general;
•material and adverse impact of the COVID-19 pandemic on the markets and the broader global economy;
•actual or anticipated fluctuations in our quarterly or annual operating results;
•the public’s reaction to our press releases, our other public announcements and our filings with the SEC;
•negative publicity regarding our company or products;
•our failure or the failure of our competitors to meet analysts’ projections or guidance that we or our competitors may give to the market;
•additions and departures of key personnel;
•changes in laws and regulations affecting its business;
•commencement of, or involvement in, litigation involving us;
•changes in our capital structure, such as future issuances of securities or the incurrence of additional debt;
•publication of research reports by securities analysts about us or our competitors or our industry;
•sales of shares of common stock by the PIPE Investors;
•the volume of shares of our common stock available for public sale, including as a result of the conversion of the Convertible Notes into shares of common stock; and
•general economic and political conditions such as recessions, changes in interest rates, an increased rate of inflation, increased costs of goods, supply chain disruptions, fuel price fluctuations, foreign currency fluctuations, international tariffs, social, political and economic risks, geopolitical conflicts (including the current conflict in Ukraine), and acts of war or terrorism.
These market and industry factors may materially reduce the market price of our common stock regardless of our operating performance.
Companies that have experienced volatility in the market price of their stock have frequently been the subject of securities class action and shareholder derivative litigation. We could be the target of such litigation in the future. Class action and derivative lawsuits, whether successful or not, could result in substantial costs, damage or settlement awards and a diversion of our management’s resources and attention from running our business, which could materially harm our reputation, financial condition and results of operations.
Conversion of the Convertible Notes will dilute the ownership interest of existing stockholders or may otherwise depress our stock price.
In August 2020, we issued $200.0 million in original aggregate principal amount of Convertible Notes, with cash interest of 5.0% per annum payable at each quarter end and PIK interest of 4.5% per annum payable by increasing the principal balance at each quarter end. Certain holders of Convertible Notes with aggregate original principal amounts of $46.5 million elected to convert their Convertible Notes, including accrued PIK interest and cash interest, at the Closing resulting in the issuance of 7.4 million shares of common stock. As of December 31, 2022, the outstanding balance of the Convertible Notes was $170.8 million iinclusive of PIK interest of $17.3 million. To the extent the remaining outstanding Convertible Notes are converted pursuant to their mandatory conversion provisions, the balance under the Convertible Notes will grow and the number of shares that may be issued upon conversion will increase accordingly. The conversion of the Convertible Notes will dilute the ownership interests of existing stockholders. Any sales in the public market of the common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of the Convertible Notes may encourage short selling by market participants because the anticipated conversion of the Convertible Notes into shares of common stock could depress our stock price.
Future resale of our common stock may cause the market price of our common stock to drop significantly, even if our business is doing well.
Sales of a substantial number of shares of common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. We have filed a registration statement related to the offer and sale from time to time by the selling securityholders named in the prospectus that forms a part of the registration statement of up to 125,389,111 shares of common stock, which registration statement has been declared effective by the SEC. In addition, as of June 17, 2022, Rule 144 became available for the resale of any shares that are restricted or control securities, subject to volume and other restrictions as applicable under Rule 144. To the extent shares are sold into the market pursuant to a registration statement that has been declared effective by the SEC, under Rule 144 or otherwise, particularly in substantial quantities, the market price of our common stock could decline.
Our management team has limited experience managing a public company.
Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could have an adverse effect our business, prospects, financial condition, and operating results.
Reports published by analysts, including projections in those reports that differ from our actual results, could adversely affect the price and trading volume of our common stock.
Securities research analysts may establish and publish their own periodic projections for us. These projections may vary widely and may not accurately predict the results we actually achieve. Our share price may decline if our actual results do not match the projections of these securities research analysts. Similarly, if one or
more of the analysts who write reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business, our share price could decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, our share price or trading volume could decline. While we expect research analyst coverage, if no analysts commence coverage of us, the market price and volume for our common stock could be adversely affected.
We are subject to changing law and regulations regarding regulatory matters, corporate governance and public disclosure that will increase our costs and the risk of non-compliance.
We are subject to rules and regulations by various governing bodies, including, for example, the SEC, which are charged with the protection of investors and the oversight of companies whose securities are publicly traded, and to new and evolving regulatory measures under applicable law. Our efforts to comply with new and changing laws and regulations will result in increased general and administrative expenses and a diversion of management time and attention.
Moreover, because these laws, regulations and standards are subject to varying interpretations, their application in practice may evolve over time as new guidance becomes available. This evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by ongoing revisions to our disclosure and governance practices. If we fail to address and comply with these regulations and any subsequent changes, we may be subject to penalty and our business may be harmed.
We do not intend to pay dividends for the foreseeable future.
We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. Additionally, our ability to pay dividends on our common stock is limited by restrictions under the terms of our Loan Agreements. We anticipate that for the foreseeable future we will retain all our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our board of directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.
Provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, limit attempts by our stockholders to replace or remove our current management, limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees, and limit the market price of our common stock.
Provisions in our certificate of incorporation and restated bylaws that are in effect may have the effect of delaying or preventing a change of control or changes in our management. Our certificate of incorporation and restated bylaws include provisions that:
•provide that our board of directors will be classified into three classes of directors with staggered three-year terms;
•permit the board of directors to establish the number of directors and fill any vacancies and newly created directorships;
•require super-majority voting (or if two-thirds of the board of directors approves, a majority) to amend some provisions in our certificate of incorporation and restated bylaws;
•authorize the issuance of “blank check” preferred stock that our board of directors could use to implement a stockholder rights plan;
•provide that only a majority of our board of directors will be authorized to call a special meeting of stockholders;
•prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;
•provide that the board of directors is expressly authorized to make, alter, or repeal our bylaws; and
•establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.
In addition, our certificate of incorporation provides the Court of Chancery of the State of Delaware, to the fullest extent permitted by law, will be the exclusive forum for any derivative action or proceeding brought on our behalf, any action asserting a breach of fiduciary duty, any action asserting a claim against us arising pursuant to the Delaware General Corporation Law (the “DGCL”), our certificate of incorporation, or our restated bylaws, or any action asserting a claim against us that is governed by the internal affairs doctrine. The provision will not apply to suits brought to enforce a duty or liability created by the Exchange Act. Our restated bylaws provide that the federal district courts of the United States of America will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act or the Exchange Act, which we refer to as a Federal Forum Provision. Our decision to adopt a Federal Forum Provision followed a decision by the Supreme Court of the State of Delaware holding that such provisions are facially valid under Delaware law. While there can be no assurance that federal courts or state courts will follow the holding of the Delaware Supreme Court or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act or the Exchange Act must be brought in federal court and cannot be brought in state court. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees.
Moreover, Section 203 of the DGCL may discourage, delay, or prevent a change of control of our company. Section 203 imposes certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock. See the section titled “Description of Capital Stock” for additional information.

ITEM 2. PROPERTIES
Item 2. Properties
Our corporate headquarters are in Burlingame, California, where we occupy facilities totaling approximately 34,400 square feet under a lease that expires in May 2025. We use these facilities for administration, finance, legal, human resources, information technology, sales and marketing, engineering, technology, and development. Our Burlingame headquarters also includes one of our battery manufacturing facilities and our test lab.
We also have bus manufacturing facilities in City of Industry, California and Greenville, South Carolina. Battery manufacturing is also in City of Industry where we lease approximately 157,100 square feet of space under a lease that expires in December 2023. In January 2023, we approved a plan to improve operational efficiency that included closing our City of Industry facility. We plan to vacate the City of Industry facility by the end of 2023. In Greenville, we lease approximately 209,300 square feet under a lease that expires in June 2026, for which we have two five-year options to extend our lease to June 2036. In November 2021, we entered into a lease arrangement for a new factory with approximately 327,000 square feet at Greer, South Carolina to expand our battery system manufacturing capacity. The lease expires in January 2032, and we have two five-year options to extend our lease to 2042.
We have in the past applied for and received state grants and tax incentives designed to promote the manufacturing of electric vehicles and related technologies. In April 2015, the California Energy Commission awarded us $3.0 million based on our investment of approximately $8.4 million in our manufacturing facilities in California through December 31, 2018. In addition, in April 2019, the California Energy Commission awarded us a $1.8 million grant based on our expected investment of approximately $4.3 million in our manufacturing facility in City of Industry, California. In connection with the planned closure of City of Industry facility by December 31, 2023, some of the assets funded by the California Energy Commission will be relocated to our Burlingame facility.
The California Energy Commission awards were made after a competitive grant solicitation that offered to fund development of advanced vehicle technology manufacturing facilities in California.
We intend to procure additional space as we add employees and expand geographically. We believe that our facilities are adequate to meet our needs for the immediate future, and that suitable additional space will be available to accommodate any expansion of our operations if needed in the future.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS
Item 7. Management’s Discussion and Analysis Of Financial Condition and Results of Operations
You should read the following discussion and analysis of our financial condition and results of operations together with our audited financial statements and notes thereto included elsewhere in this Annual Report. Certain of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report, including information with respect to plans and strategy for Proterra’s business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the section entitled “Risk Factors,” Proterra’s actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the section entitled “Risk Factors” to gain an understanding of the important factors that could cause actual results to differ materially from Proterra’s forward-looking statements.
Overview
Proterra’s mission is to advance electric vehicle technology to deliver the world’s best performing commercial vehicles.
Driven by factors including emissions targets and regulations, and lower operating costs, commercial and industrial fleets are expected to adopt electric vehicles at increasingly higher rates over the next two decades. More than 200,000 new electric buses, medium-duty trucks, and heavy-duty trucks are expected to be sold in the industry by 2030 and approximately 650,000 by 2040 in our core markets of North America and Europe. Assuming average battery capacity per vehicle of 225 kWh for medium-duty trucks, 300 kWh for buses and 750 kWh for heavy-duty trucks, we estimate this could translate into demand for heavy-duty commercial and industrial-scale batteries of approximately 90 GWh in 2030 and approximately 300 GWh in 2040 in such markets. Our business strategy is to capitalize on this opportunity.
In the first quarter of 2023, we announced the appointment of Julian Soell as the Chief Operating Officer of the Company, and Christopher Bailey as Chief Business Officer of the Company, each appointment effective as of March 1, 2023. With these appointments, we consolidated all of our product lines under one Chief Business Officer and all our operations under one Chief Operating Officer, from organizing our business around business groups (called Proterra Transit and Proterra Powered and Energy, respectively) each lead by a President. In addition, we announced workforce restructuring plans designed to improve operational efficiency with the reduction of our workforce by up to twenty five percent or the elimination of approximately 300 jobs and the closure of our City of Industry manufacturing facility by December 31, 2023.
We have three commercial offerings each addressing a critical component of commercial vehicle electrification.

Proterra Powered products are our proprietary battery systems and electrification solutions for global commercial vehicle original equipment manufacturer (“OEM”) customers serving the Class 3 to Class 8 vehicle segments, including delivery trucks, school buses, and coach buses, as well as construction and mining equipment, and other applications. Proterra Energy products
and services offer turnkey fleet-scale, high-power charging solutions and software services, ranging from fleet and energy management software-as-a-service, to fleet planning, hardware, infrastructure, installation, utility engagement, and charging optimization. These solutions are designed to optimize energy use and costs, and to provide vehicle-to-grid functionality.
•Proterra Transit. We design, develop, manufacture, and sell electric transit buses as an OEM for North American public transit agencies, airports, universities, and other commercial transit fleets. Proterra Transit vehicles showcase and validate our electric vehicle technology platform through rigorous daily use by a large group of sophisticated customers focused on meeting the wide-ranging needs of the communities they serve.
The first application of Proterra Powered commercial vehicle electrification technology was through Proterra Transit’s heavy-duty electric transit bus, which we designed from the ground up for the North American market. Our industry experience, the performance of our transit buses, and compelling total cost of ownership has helped make us a leader in the U.S. electric transit bus market. With over 1,000 electric transit buses delivered, our electric transit buses currently have delivered more than 35 million cumulative service miles spanning a wide spectrum of climates, conditions, altitudes and terrains. From this experience, we have been able to continue to iterate and improve our technology.
Our decade of experience supplying battery electric heavy duty transit buses provided us the opportunity to validate our products’ performance, fuel efficiency and maintenance costs with a demanding customer base and helped broaden our appeal as a supplier to OEMs in other commercial vehicle segments and geographies. Proterra Powered has partnered with more than a dozen OEMs spanning from Class 3 to Class 8 trucks, several types of buses, and multiple off-highway categories. Through December 31, 2022, Proterra Powered has delivered battery systems and electrification solutions for more than 1,600 vehicles to our OEM partner customers.
In addition, Proterra Energy has established us as a leading commercial vehicle charging solution provider by helping fleet operators fulfill the high-power charging needs of commercial electric vehicles and optimize their energy usage, while meeting our customers’ space constraints and continuous service requirements. As of December 31, 2022, we had installed more than 95 MW of charging infrastructure across North America, predominantly for electric transit bus and school bus customers.
Through December 31, 2022, we have generated the majority of our revenue from Proterra Transit’s sales of electric transit buses, complemented by additional revenue from Proterra Powered’s sales of battery systems and Proterra Energy’s sales and installation of charging systems, as well as from the sale of spare parts and other services provided to customers. As fleet electrification continues to expand beyond buses to trucks and other commercial vehicles, we expect Proterra Powered & Energy to grow into a significantly larger portion of our overall business and generate a greater portion of revenue. Through December 31, 2022, our chief operating decision maker, the Chief Executive Officer, evaluated our results on a consolidated basis for purposes of making decision on allocating resources and assessing financial performance, resulting in a single reportable segment.
Enhanced by Proterra PoweredTM high performance battery systems and electrification solutions and our purpose-built transit bus vehicle designed to optimize power, weight, and efficiency, Proterra Transit has been a leader in the North American electric transit market since 2012. Our sales efforts are focused on the 400 largest public transit agencies, which range in size from approximately 50 buses to thousands of buses in their fleets. These agencies operate more than 85% of the more than 70,000 transit buses on the road in North America, according to the FTA’s National Transit Database. We also focus our sales effort on airports, universities, hospitals, and corporate shuttle operators. As of December 31, 2022, there are, in aggregate, more than 25,000 buses in operation at fleets that are mandated to convert to 100% zero-emission by 2040 in North America, including fleets in the state of California and the cities of New York City, Chicago, and Seattle, among others. The fleet size of our primary public transit agency customer targets ranges between approximately 100 to more than 4,000 buses, and their electrification plans typically involve a phased approach. Our strategy is to maintain our leadership in market share of the North American electric transit bus market as electric penetration continues to rise by both acquiring new customers and expanding our share of existing customers as transit agencies’ average order rates increase to meet their zero emission targets. We believe we have a competitive advantage in winning new bus sales due to our extensive track record, with more than 1,000 vehicles delivered and more than 35
million real-world service miles spanning a wide spectrum of climates, conditions, altitudes and terrains. We believe that repeat orders of increasing scale represent a considerable growth opportunity for our electric transit buses. After initial purchase, our customers often expand their electric vehicle programs and place additional orders for electric buses and charging systems. Repeat orders lower our customer acquisition costs and increase visibility into our sales pipeline. Many of our existing customers have announced long-term goals to transition to fleets completely comprised of electric vehicles.
We have a long sales and production cycle given our customers’ structured procurement processes and vehicle customization requirements, and believe that our proven ability to deliver commercial-quality battery systems, electrification and charging solutions, and electric transit buses gives us a distinct first mover advantage in end markets that are electrifying rapidly. For Proterra Powered, new vehicle development programs for commercial vehicle OEMs typically last between one and three years. As a result, volume production and revenue generation tend to trail initial contract signatures by a few years. For Proterra Transit, public transit agencies typically conduct a request for proposal process before awards are made and purchase orders are issued. Proposals are evaluated on various criteria, including but not limited to technical requirements, reliability, reputation of the manufacturer, and price. This initial sales process from first engagement to award typically ranges from 6 to 18 months. Once a proposal has been awarded, a pre-production process is completed where customer specific options are mutually agreed upon. A final purchase order follows the pre-production process. Procurement of parts and production typically follow the purchase order. Once a bus is fully manufactured, the customer performs a final inspection before accepting delivery, allowing us to recognize revenue. The length of time between a customer award and vehicle acceptance typically varies between 12 and 24 months, depending on product availability and production capacity.
We are consolidating our bus production to our largest bus manufacturing facility located in Greenville, South Carolina. We constructed our Powered 1 battery factory which has approximately 327,000 square feet at Greer, South Carolina. Our total battery system manufacturing capacity is multiple gigawatt-hours per year. We have specifically developed our battery modules using a design for manufacturability (DFM) approach that enables high-volume automated production of the module using a modular manufacturing line that can be rapidly built with low capital expenditures. Enabled by the simplicity of design and integrated architecture of our battery modules, we can manufacture our battery packs in two widths and three heights, various lengths ranging from 3-feet to 9-feet, and four different voltages. In the year ended December 31, 2021, our battery production was 189 MWh and in the year ended December 31, 2022, our battery production was 342 MWh, a 81% increase year over year. As we increase our production volumes and complete construction of our Powered 1 battery factory, and improve manufacturing efficiency across our production assets as we scale, we believe that we will be able to leverage our historical investments in capacity to reduce our labor and overhead costs as a percentage of total revenue. With the addition of our Powered 1 factory, we believe we will have sufficient capacity to fulfill our current backlog and anticipated near-term growth but further investment in capacity will be required as demand for electric vehicles continues to grow globally.
For the years ended December 31, 2022, 2021 and 2020, our total revenue was $309.4 million, $242.9 million, and $196.9 million, respectively. As of December 31, 2022, in aggregate, we have generated revenue of $749.2 million for the past three years. We generated a gross loss of $24.0 million for the year ended December 31, 2022 and a gross profit of $2.1 million and $7.5 million for the year ended December 31, 2021 and 2020, respectively. We have also invested significant resources in research and development, operations, and sales and marketing to grow our business and, as a result, generated losses from operations of $220.9 million, $127.6 million, and $96.0 million for the years ended December 31, 2022, 2021 and 2020, respectively.
We intend to continue to make investments in developing new products and enhancing existing products. In 2022, we made a strategic equity investment in a privately held entity that we expect to produce lithium iron phosphate (LFP) battery cells in the United States in the coming years to provide us with development opportunities for battery packs with another cell chemistry to address additional segments of the commercial vehicle market. We are also increasing and/or optimizing our production capacity, and also expect to make investments in our sales and marketing organizations as well as those expenses associated with operating as a public company. As a result, we expect that the cost of goods sold and operating expenses will increase with total revenue in absolute dollars in future periods but decline as a percentage of total revenue over time.
Key metrics
Deliveries
We delivered 213 (199 new and 14 pre-owned), 217 (208 new and 9 pre-owned) and 170 vehicles in 2022, 2021 and 2020, respectively. We delivered battery systems for 1,229, 273 and 107 vehicles in 2022, 2021 and 2020, respectively.
Deliveries is an indicator of our ability to convert awarded orders into revenue and demonstrates the scaling of our operations. We expect volume of deliveries to vary every quarter and not be linear as product configurations vary in complexity and timing for completion is not standard. Vehicles delivered represents the number of buses that have met revenue recognition criteria during a period. Battery systems delivered represents the battery systems sold to OEMs that have met revenue recognition criteria during a period and is measured based on the number of underlying vehicles in which they are to be used. In addition to batteries, battery systems could include drivetrains and high voltage systems and controls, depending upon the customer contract.
Growth rates between deliveries and total revenue are not perfectly correlated because our total revenue is affected by other variables, such as the mix of products sold during the period or other services provided in addition to the hardware delivered.
Key factors affecting our performance
Supply Chain Disruption, Materials Costs and Economic Impacts
The outbreak of the novel coronavirus COVID-19, which was declared a pandemic by the World Health Organization on March 11, 2020, has led to adverse impacts on the U.S. and global economies and created uncertainty regarding potential impacts to our supply chain, operations, and customer demand. The recent increase in inflation, interest rates and energy costs and continued disruption in global markets (in part stemming from the conflict in Ukraine) have further impacted supply chain stability and material costs. Our vehicle and charging system deliveries were impacted, especially during the three months ended March 31, 2022 and three months ended December 31, 2022, by ongoing constraints and inefficiencies in production driven in part by shortages in component parts, particularly wiring harnesses, resulting from global supply chain disruptions stemming from the pandemic and supplier instability. Although we achieved revenue growth during the year ended December 31, 2022 compared to the year ended December 31, 2021, these disruptions decreased our production which negatively impacted our revenue and increased our overhead, led to increased costs to secure components critical to our production needs and negatively impacted our margins. Our transit bus production in particular was impacted in 2022 by availability of wiring harnesses and other parts shortages, and we have qualified additional suppliers for wiring harnesses in early 2023 to mitigate that issue going forward. However, we still expect that our results for 2023 across all of our product lines will continue to be impacted by supply chain issues, including parts shortages.
More generally, raw material and component price inflation, and increased freight and logistics costs in addition to parts shortages are currently expected to continue to have an impact on our results of operations, financial position, and liquidity. If supply chain disruptions, shipment delays, part shortages, production inefficiencies, extended customer order and acceptance processes are prolonged or worsen, or if supplier credit terms are unfavorable as a result of our current financial condition, it could lead to more significant delays in production, the signing of new customer contracts and customer acceptances of near-term deliveries.
Ability to sell additional powertrains, vehicles, chargers and other products to new and existing customers
Our results will be impacted by our ability to sell our battery systems, electrification solutions including charging and energy management software, and electric transit buses, to new and existing customers. We have had initial success with Proterra Powered establishing strategic partnerships and with Proterra Transit selling electric transit buses and chargers to transit agencies, universities and airports. Our growth opportunity is dependent on commercial vehicle manufacturers electrifying their product offerings and increasing production as well as transit agencies electrifying more of their fleets (both of which we believe will increase with continued improvement in battery performance and costs over time), as well as our ability to increase manufacturing
capacity and secure supply of key components, including battery cells, to meet expected demand, and our reputation in the market. Our ability to sell additional products to existing customers is a key part of our success, as follow-on purchases indicate customer satisfaction and decrease the likelihood of competitive substitution. In order to sell additional products to new and existing customers, we will need to continue to invest significant resources in our products and services, and our manufacturing capacity and supply chain, and demonstrate our reliability as a partner both in terms of our financial condition and product quality and customer service. If we fail to make the right investment decisions in our technology and electrification solutions, including our battery systems and electrification and charging solutions, and our manufacturing facilities and supply chain initiatives, if customers do not adopt our technology or our products and services or we cannot timely deliver products to customers due to supply chain disruptions or otherwise, or if our competitors are able to develop and deliver technology or products and services that are superior to ours, our business, prospects, financial condition, and operating results could be adversely affected.
Ability to improve profit margins and scale our business
We intend to continue investing in initiatives to improve our operating leverage and significantly ramp production. We believe continued reduction in costs and an increase in production volumes will enable commercial vehicle manufacturers to electrify faster. Purchased materials represent the largest component of cost of goods sold in all products and we continue to explore ways to reduce these costs through improved design for cost, strategic sourcing, long-term contracts, and in some cases vertical integration. We are consolidating battery and bus manufacturing to our facilities in Greer and Greenville South Carolina. We completed construction of our first multi-gigawatt capacity battery production facility in Greer, which began production in January 2023. We believe that an increase in volume and additional experience will allow us to leverage those investments and reduce our labor and overhead costs, as well as our freight costs, as a percentage of total revenue. We expect our product cost of goods sold to increase in absolute dollars in future periods as the volume of products we sell increases. As we grow into our current capacity, execute on cost-reduction initiatives, and improve production efficiency, we expect our product cost of goods sold as a percentage of revenue to decrease in the longer term. We anticipate that by increasing facility utilization rates and improving overall economies of scale, we can positively impact gross margins of our products, bring value to our customers and help accelerate commercial electric vehicle adoption. Our ability to achieve cost-saving and production-efficiency objectives can be negatively impacted by a variety of factors including, among other things, labor cost inflation, lower-than-expected facility utilization rates, rising real estate costs, manufacturing and production cost overruns, increased purchased material costs, and unexpected supply-chain quality issues or interruptions, and delays in our ability to hire, train, and retain employees needed to scale production to meet demand.
Continued emissions regulation and environmental stewardship
Our business benefits from international, federal, state, and local government interest in regulating air pollution and greenhouse gas emissions that contribute to global climate change. In July 2020, 15 states, including California and New York, pledged to work jointly towards a unified goal of zero emissions for 100% of new sales of medium- and heavy-duty commercial vehicles by 2050. In August 2019, the European Union passed Regulation 2019/1242, mandating a reduction in emissions from new trucks by 2025 and 2030. In addition, a growing number of cities and transit agencies have pledged to convert their entire transit bus fleets to zero-emission vehicles by a specific target date, and many have already begun to purchase electric vehicles in order to meet this goal. For example, on December 14, 2018, the California Air Resources Board adopted a state-wide mandate, the Innovative Clean Transit Rule, mandating transit agencies to commit to purchasing zero-emission buses starting in 2029. The move away from diesel- and natural gas-powered commercial vehicles is a significant step forward to accelerate the use of advanced technologies in medium- and heavy-duty vehicles to meet air quality and public health goals, thereby boosting near-term deployment of battery-electric commercial vehicles. As legacy internal combustion engine technology becomes more heavily regulated and costly across the globe, commercial vehicle manufacturers are investing in electrification. While this investment may increase competition, we believe that it will also increase customer demand, and help build the necessary supply chain and adjacent industry investments to support powertrain electrification. However, the uncertainty related to the passage of new legislation, appropriation of government funding, and implementation of regulations could impact the timing and number of vehicle orders, and any reduction in governmental interest in emissions regulation could negatively impact our business prospects or operating results.
Government programs accelerating adoption of zero-emission vehicles
Federal and state funding has accelerated the adoption of electric vehicles in our target markets. For instance, our U.S. transit customers have partially funded electric bus purchases through competitive grant programs, including the Low or No Emission Vehicle Program authorized by the federal Fixing America’s Surface Transportation Act in 2015, and other state-specific funding. The Infrastructure Investment and Jobs Act enacted on November 15, 2021 authorizes additional funding for electric vehicles and electric vehicle charging infrastructure through the creation of new programs and grants and the expansion of existing programs, including over $4.0 billion to replace existing buses with zero emission buses and at least $2.5 billion to replace existing school buses with zero emission school buses. In August 2022, the Inflation Reduction Act added additional funding and tax credit programs for both passenger car and commercial vehicles, many of which will become available to recipients in 2023. In the United States, states are also allocating portions of settlement funds from the approximately $15 billion Volkswagen Emissions Settlement Program to investments in zero-emission transit buses and school buses. We expect that the availability of this now unprecedented level of government funding for our customers, suppliers, and competitors to help fund purchases of commercial electric vehicles and battery systems will remain an important factor in our company’s growth prospects.
Components of results of operations
Revenue
We derive revenue primarily from the sale of vehicles, the sale of battery and powertrain systems, the sale and installation of charging systems, as well as the sale of spare parts and other services provided to customers.
Product revenue. Product revenue consists of revenue earned from the sale of vehicles, sale of battery and powertrain systems as well as sales and installation of charging systems. A vehicle is considered delivered once met revenue recognition criteria. Revenue from sales of vehicles and charging systems is typically recognized upon delivery when we can objectively demonstrate that the criteria specified in the contractual acceptance provisions are achieved prior to delivery. In cases, where we cannot objectively demonstrate that the criteria specified in the contractual acceptance provisions have been achieved prior to delivery, revenue is recognized upon acceptance by the customer. Under certain contract arrangements, revenue related to the charging systems is recognized over the installation period using an input measure based on costs incurred to date relative to total estimated costs to completion. Revenue from the sale of battery and powertrain systems is typically recognized upon shipping. Product revenue also includes revenue from leasing vehicles and charging systems under operating leases. Revenue from operating lease arrangements is recognized ratably over the lease term. The amount of product revenue we recognize in a given period depends on the number of products delivered and the type of financing used by the customer.
Parts and other service revenue. Parts and other service revenue includes sales of spare parts, revenue earned from the development of electric vehicle powertrain components, the design and development of battery and drive systems for other vehicle manufacturers, and sales of extended warranties. The amount of parts and service revenue tends to grow with the number of vehicles delivered. However, variability can exist as customers have different methodologies for sourcing spare parts for their fleets. Revenue related to the design, development and integration of battery and drive systems is typically recognized upon shipping or delivery of services and prototypes, depending on the terms in customer contracts.
For a description of our revenue recognition policies, see the section titled “- Critical Accounting Policies and Estimates.”
Cost of goods sold
Product cost of goods sold. Product cost of goods sold consists primarily of direct material and labor costs, manufacturing overhead, other personnel-related expenses, which include salaries, bonuses, benefits, and stock-based compensation expense, reserves for estimated warranty costs, freight expense, and depreciation expense. Product cost of goods sold also includes charges to write-down the carrying value of inventory when it exceeds its estimated net realizable value, including on-hand inventory that is either obsolete or in excess of forecasted demand. We expect our product cost of goods sold to increase in absolute dollars in future periods as the volume
of products we sell increases. As we grow into our current capacity, execute on cost-reduction initiatives, and improve production efficiency, we expect our product cost of goods sold as a percentage of revenue to decrease in the longer term.
Parts and other service cost of goods sold. Parts and other service cost of goods sold consists primarily of material costs and the cost of services provided, including field service costs and costs related to our development team. We record costs of development services incurred in periods prior to the finalization of an agreement as research and development expense. Once a development agreement is finalized, we record these costs in parts and other service cost of goods sold. We expect our parts and other service cost of goods sold to increase in absolute dollars in future periods as more customers put additional vehicles into service and sign new development agreements.
Gross profit (loss) and margin
Gross profit (loss) is total revenue less total cost of goods sold. Gross margin is gross profit (loss) expressed as a percentage of total revenue. Our gross profit (loss) and margin has and may in the future fluctuate from period-to-period. Such fluctuations have been and will continue to be affected by a variety of factors, including the timing of vehicle delivery, mix of products sold, manufacturing costs, financing options, and warranty costs. We expect our gross margin to improve over time as we continue to scale our operations and execute on cost reduction initiatives in the longer term.
Operating expenses
Research and development. Research and development expense consists primarily of personnel-related expenses, consulting and contractor expenses, validation and testing expense, prototype parts and materials, depreciation expense, and allocated overhead costs. Software development costs related to our fleet and energy management platform are expensed as incurred if the capitalization criteria are not met. We intend to continue to make significant investments in developing new products and enhancing existing products. Research and development expense will be variable relative to the number of products that are in development, validation or testing. However, we expect it to decline as a percentage of total revenue over time.
Selling, general and administrative. Selling, general and administrative expenses consist primarily of personnel-related expenses for our sales, marketing, supply chain, finance, legal, human resources, and administrative personnel, as well as the costs of customer service, information technology, professional services, insurance, travel, allocated overhead, and other marketing, communications and administrative expenses. We will continue to actively promote our products. We also expect to invest in our corporate organization and incur additional expenses associated with operating as a public company, including increased legal and accounting costs, investor relations costs, higher insurance premiums, and compliance costs. As a result, we expect that selling, general and administrative expenses will increase in absolute dollars in future periods but decline as a percentage of total revenue over time.
Interest expense, net
Interest expense, net consists primarily of interest expense associated with our debt facilities and amortization of debt discount and issuance costs. Interest income consists primarily of interest income earned on our cash and cash equivalents and short-term investments balances.
Gain on debt extinguishment
Gain on debt extinguishment relates to the forgiveness of the PPP loan.
(Gain) loss on valuation of derivative and warrant liabilities
(Gain) loss on valuation of derivative and warrant liabilities relates to the changes in the fair value of derivative and warrant liabilities, which were subject to remeasurement at each balance sheet date.
Other expense (income), net
Other expense (income), net primarily relates to sublease income and currency fluctuations that generate foreign exchange gains or losses on invoices denominated in currencies other than the U.S. dollar, amortization of short-term investment premium/discount and other non-operational financial gains or losses.
Provision for income taxes
We are subject to income taxes in the United States and certain states. Due to our net operating loss position, we have not recognized any material provision or benefit through December 31, 2022.
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. A valuation allowance is provided when it is more likely than not that the deferred tax assets will not be realized. We have established a full valuation allowance to offset our U.S. net deferred tax assets due to the uncertainty of realizing future tax benefits from our net operating loss carryforwards and other deferred tax assets.
As of December 31, 2022, we had U.S. federal net operating loss carryforwards of $729.5 million, and state net operating loss carryforwards of $531.1 million. The federal net operating loss carryforwards generated prior to 2018 will begin to expire in 2030, and the federal net operating loss carryforwards generated since 2018 do not expire. The state net operating loss carryforwards will begin to expire in 2023. Also, as of December 31, 2022, we had U.S. federal research and development tax credit carryforwards of $7.2 million, and state research and development tax credit carryforwards of $4.3 million. The federal research credits begin to expire in 2037, and the South Carolina research and development tax credit carryforwards begin to expire in 2027. California state research and development tax credit carryforwards have no expiration date. Our ability to use net operating loss carryforwards and other tax attributes to reduce future taxable income and liabilities may be subject to limitations based on possible ownership changes in the future. As a result, if we earn net taxable income, our ability to use our pre-change net operating loss carryforwards or other pre-change tax attributes to offset U.S. federal and state taxable income may still be subject to limitations, which could potentially result in increased future tax liability to us. Additionally, a challenge by a taxing authority, a change in our ability to utilize tax benefits such as carryforwards or tax credits, or a deviation from other tax-related assumptions may cause actual financial results to deviate from previous estimates.
Critical accounting policies and estimates
The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates, assumptions, and judgments that affect amounts of assets and liabilities reported in the financial statements, the disclosure of contingent assets and liabilities as of the date of the financial statements and reported amounts of revenues and expenses during the applicable periods. We base our estimates, assumptions, and judgments on historical experience and on various other factors that we believe to be reasonable under the circumstances. Different assumptions and judgments would change the estimates used in the preparation of our financial statements, which, in turn, could change the results from those reported. We evaluate our estimates, assumptions, and judgments on an ongoing basis. The critical accounting estimates, assumptions, and judgments that we believe have the most significant impact on our financial statements are described below.
Revenue recognition
We recognize revenue in accordance with ASC 606, Revenue from Contracts with Customers. We determine the amount of revenue to be recognized through the application of the following steps: (1) identify the contract; (2) identify the performance obligations; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations; and (5) recognize revenue when (or as) performance obligations are satisfied.
We derive revenue primarily from the sale of vehicles and charging systems, the installation of charging equipment, and the sale of batteries and powertrain components to other vehicle manufacturers, as well as the sale of spare parts and other services provided to customers. Customer contracts typically have multiple performance obligations. Generally, our goods and services are considered separate performance obligations.
Development services and products sold to other vehicle manufacturers are typically sold on a stand-alone basis and are not bundled with other goods or services.
The transaction price of the contract is allocated to each performance obligation in a manner depicting the amount of consideration to which the Company expects to be entitled in exchange for transferring the goods or services to the customer (the “allocation objective”). If the allocation objective is met at contractual prices, no further allocations are made. Otherwise, the Company allocates the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis.
We recognize revenue when or as we satisfy a performance obligation by transferring control of a product or service to a customer. Amounts collected in advance of meeting all of the revenue recognition criteria are not recognized in the statement of operations and are instead recorded as deferred revenue on the balance sheets.
Warranty
We provide a limited warranty to customers on vehicles, charging systems, and battery and powertrain systems. The limited warranty ranges from one to twelve years depending on the components. Separately, we also periodically perform field service actions related to product service campaigns. Pursuant to these warranties and field service actions, we will repair, replace, or adjust the parts on the products that are defective in factory-supplied materials or workmanship. We record a warranty reserve for the products sold at the point of revenue recognition, which includes the best estimate of the projected costs to repair or replace items under the limited warranty and field service actions. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency, and costs of future claims. These estimates are inherently uncertain given our relatively short history of sales, and changes to the historical or projected warranty experience may cause material changes to the warranty reserve in the future. The warranty reserve does not include projected warranty costs associated with the products subject to lease accounting, as the costs to repair these warranty claims are expensed as incurred. The portion of the warranty reserve expected to be incurred within the next twelve months is included within accrued liabilities while the remaining balance is included within other long-term liabilities on the balance sheets.
Stock-based compensation expense
We use the fair value method for recording stock-based compensation expense. Stock-based compensation expense for stock options is estimated at the grant date based on each stock option’s fair value as calculated using the Black-Scholes option pricing model. We recognize stock-based compensation expense for stock option grants on a straight-line basis over the requisite service period for the entire award.
Determining the fair value of stock-based awards at the grant date requires judgment. The determination of the grant date fair value of stock options using an option pricing model is affected by our estimated common stock fair value prior to the Merger Close, as well as assumptions regarding a number of complex and subjective variables. The major subjective assumptions used in the Black-Scholes option pricing model are estimated as follows:
Expected volatility. Since the Company has limited trading history by which to determine the volatility of its own common stock price, the expected volatility being used is primarily derived from the historical stock volatility of a representative industry peer group of comparable publicly listed companies over a period approximately equal to the expected term of the stock options.
Common stock valuations. Historically, for all periods prior to our Merger Close, the fair value of our common stock was determined by our board of directors, with input from management, taking into account our most recent valuations from an independent third-party valuation firm. Our board of directors intended all stock options granted to have an exercise price per share not less than the per share fair value of our common stock on the date of grant. The valuations of our common stock were determined in accordance with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions we use in the valuation models were based on future
expectations combined with management judgment, and considered numerous objective and subjective factors to determine the fair value of our common stock as of the date of each option grant, including the following factors:
•the liquidation preferences, rights, and privileges of our convertible preferred stock relative to the common stock;
•our actual operating and financial performance;
•current business conditions and projections;
•our stage of development;
•the likelihood and timing of achieving a liquidity event for the shares of common stock underlying the stock options, such as an initial public offering or sale of our company, given prevailing market conditions;
•any adjustment necessary to recognize a lack of marketability of the common stock underlying the granted options;
•the market performance of comparable publicly traded companies; and
•U.S. and global capital market conditions.
In valuing our common stock, our board of directors relied in part upon independent third-party valuation reports to determine the equity value of our business using various valuation methods including combinations of income and market approaches with input from management.
In August 2020, we issued Convertible Notes that contain several conversion options. The Monte Carlo simulation was the most appropriate valuation method given the variability of distributions to different share classes depending on the conversion terms upon various potential exit events of the Company and considering that the likelihood of such exit events and potential exit values were speculative as of the valuation date.
Application of these approaches involves the use of estimates, judgment, and assumptions that are highly complex and subjective, such as those regarding our expected future revenue, expenses, and future cash flows, discount rates, market multiples, the selection of comparable companies, and the probability of possible future events. Changes in any or all of these estimates and assumptions or the relationships between those assumptions impact our valuations as of each valuation date and may have a material impact on the valuation of our common stock.
Inventory
Inventories are recorded at the lower of cost and net realizable value using the first-in, first-out method. Inventory costs consist primarily of the costs of materials, manufacturing support costs, including labor and factory overhead associated with such production, and shipping costs. We assess the valuation of inventory and periodically record a provision, which increases cost of goods sold, to adjust inventory to its estimated net realizable value, including when we determine inventory to be in excess of anticipated demand or obsolete. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up.

Total revenue increased by $66.5 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. The increase in total revenue was primarily due to increased delivery of battery systems and charging systems. The new bus delivery slightly decreased, but we also delivered 14 pre-owned buses in the year
ended December 31, 2022, which increased from 9 pre-owned buses in the year ended December 31, 2021. For the year ended December 31, 2022, our production and deliveries were negatively impacted by parts shortages. Both production and deliveries during fiscal year 2021 were negatively impacted by the COVID-19 pandemic due to supplier constraints and delays in equipment delivery.
Total revenue increased by $45.9 million in the year ended December 31, 2021 compared to the year ended December 31, 2020. The increase of total revenue was primarily due to increase of vehicle and battery systems deliveries. In addition, we also delivered 9 pre-owned buses in the year ended December 31, 2021. The charging systems and installation revenue decreased due to delay in equipment delivery. Both production and deliveries during fiscal year 2020 were negatively impacted by the COVID-19 pandemic due to inefficiencies experienced with required safety measures and complications with inspections and regulatory testing. Both production and deliveries during fiscal year 2021 were negatively impacted by the COVID-19 pandemic due to supplier constraints and delays in equipment delivery.

Gross profit (loss) $ (23,991) $ 2,052 $ 7,539 $ (26,043) NM $ (5,487) (73)%
Cost of goods sold increased by $92.5 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. The increase in costs were mainly driven by the increased product volume, higher material input costs and growth in personnel related costs due to inflation and global supply chain interruption. To support the growth in demand for our products, we increased headcount since 2021. However, parts shortages in part caused delays in production, which negatively impacted our ability to absorb such increased labor and manufacturing overhead costs and also, in part, resulted in a purchase commitment shortfall penalty for volumes committed in 2022 and 2023 volume modification totaling $7.7 million to our bus body supplier incurred in the fourth quarter of 2022. In addition, the cost of goods sold for the year ended December 31, 2022 also included $6.3 million related to start-up costs for the Powered 1 battery factory, which was under construction, and $3.0 million year end inventory adjustment.
Gross profit decreased by $26.0 million for the year ended December 31, 2022 compared to the year ended December 31, 2021, which was mainly due to the unabsorbed labor and manufacturing overhead costs and supplier purchase shortfall penalty incurred in the fourth quarter of 2022 from delayed production caused in part by parts shortages, start-up costs for the Powered 1 battery factory, and our high mix of deliveries with pre-inflation pricing and higher material input costs.
Cost of goods sold increased by $51.4 million in the year ended December 31, 2021 compared to the year ended December 31, 2020. The $47.2 million increase in product cost of goods sold was mainly driven by an increase in vehicle and battery systems delivered. To support the growth, we have increased headcount, however, COVID-19 related supply chain interruptions caused delays in production, which negatively impacted our ability to absorb such increased labor and manufacturing overhead costs.
Gross profit decreased by $5.5 million for the year ended December 31, 2021 compared to the year ended December 31, 2020, which was mainly due to the unabsorbed labor and manufacturing overhead costs from delayed production caused by parts shortages stemming from the COVID-19 related supply chain interruption.

Research and development expense increased by $19.8 million in the year ended December 31, 2022 compared to the year ended December 31, 2021. The increase was primarily due to an increase in personnel related expenses of $8.6 million and stock-based compensation of $2.8 million, an increase in prototype parts and tools expense of $3.7 million, an increase of travel expense of $1.6 million as a result of the relaxation of COVID-19 restrictions, and an increase in professional and consulting fees of $1.4 million to support increased product development efforts.
Research and development expense increased by $7.6 million in the year ended December 31, 2021 compared to the year ended December 31, 2020. The increase was primarily due to an increase in personnel related expenses of $6.4 million and stock-based compensation of $0.9 million, and an increase in professional and consulting fees to support increased product development efforts, and an increase in IT expense. These increases were partially offset by a decrease in prototype parts and tools expense of $1.5 million following the completion of the development of the advanced composite bus body and the ZX5 bus platform.

Selling, general and administrative expense increased by $47.4 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to an increase in personnel related expenses of $19.5 million and stock-based compensation of $2.6 million, an increase in professional and consulting fees of $8.7 million, an increase in IT expense of $4.9 million due to increased cybersecurity measures, more users and incremental data usage costs, an increase in facilities expense of $3.6 million, an increase in insurance expense of $2.6 million, and an increase in travel expense of $1.4 million as a result of the relaxation of COVID-19 restrictions.
Selling, general and administrative expense increased by $18.7 million in the year ended December 31, 2021 compared to the year ended December 31, 2020 primarily due to an increase in personnel related expenses of $7.3 million and stock-based compensation of $4.4 million, an increase in insurance expense of $3.5 million, an increase in IT expense of $2.0 million due to increased cybersecurity measures, more users and incremental data usage costs, and an increase in travel expense of $1.2 million as a result of the relaxation of COVID-19 restrictions.

Interest expense, net decreased by $22.4 million in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to the write-off of $21.0 million of unamortized debt issuance costs associated with the Convertible Notes with an original aggregate principal of $46.5 million that were converted
upon the Closing of the Business Combination in June 2021. For more information regarding the Convertible Notes, see “-Liquidity and capital resources” below.
Interest expense, net increased by $35.6 million in the year ended December 31, 2021 compared to the year ended December 31, 2020 primarily due to the write-off of $21.0 million of unamortized debt issuance costs associated with the Convertible Notes with an original aggregate principal of $46.5 million that were converted upon the Closing of the Business Combination, and additional interest expense resulting from the original aggregate principal of $200.0 million of Convertible Notes issued in August 2020. These amounts were offset by increased interest income earned on investments from cash equivalents and short-term investments.

The $70.2 million loss in the year ended December 31, 2021 was related to losses on revaluation of the derivative and warrant liabilities arising from the Convertible Notes and related warrants of $111.7 million and $47.3 million, respectively, offset by the $50.3 million and $38.6 million of gains recognized on revaluation of the liabilities arising from the public warrants and private placement warrants, respectively.
The derivative and remaining warrant liabilities arising from the Convertible Notes were reclassified to stockholder’s equity upon the Closing in June 2021. The public and private placement warrants were exercised or redeemed in October 2021, and the related warrant liabilities were reclassified to stockholder’s equity.
The $13.0 million loss in the year ended December 31, 2020 related to the fair value change of derivative and warrant liabilities arising from the Convertible Notes.

Other expense (income), net includes realized gain or loss from short-term investment, currency fluctuations that generate foreign exchange gains or losses on invoices denominated in currencies other than the U.S. dollar, sublease income and other non-operational financial losses. The increase of other income in the year ended December 31, 2022 compared to the year ended December 31, 2021 primarily due to higher amount of ST investment throughout 2022 compared to 2021.
The higher expense in the year ended December 31, 2020 was mainly due to foreign exchange rate fluctuations in the first quarter of 2020, and other non-operational financial gains or losses.

We are subject to income taxes in the United States and certain states, but due to our net operating loss position, we have not recognized any material provision or benefit through December 31, 2022. In the years ended December 31, 2021 and 2020, we recorded a provision for taxes in certain states, where tax is not based solely on income before taxes.
Liquidity and capital resources
As of December 31, 2022, we had cash and cash equivalents and short-term investments of $298.1 million. Our primary requirements for liquidity and capital are investment in new products and technologies, the completion and improvement of our current manufacturing and future capacity expansion, working capital, debt service, and general corporate needs. Historically, these cash requirements have been met through the net proceeds we received through private sales of equity securities, the Business Combination, the PIPE Financing, borrowings under our credit facilities, and payments received from customers.
Under ASC Subtopic 205-40, Presentation of Financial Statements-Going Concern (“ASC 205-40”), we have the responsibility to evaluate whether conditions and/or events raise substantial doubt about our ability to meet our future financial obligations as they become due within one year of the financial statements being issued.
Pursuant to the terms of the purchase agreement governing the Convertible Notes, we are required to maintain Liquidity (as defined therein) as of the last day of each quarter of not less than the greater of (a) $75.0 million and (b) an amount equal to the product of multiplying (i) the amount of Cash Burn (as defined therein) from operations for the three-month period ending on the end of such month by (ii) four (the “Minimum Liquidity Covenant”).
As of December 31, 2022, we did not have Liquidity in an amount equal to clause (b) above as of such date. As a result, we obtained a waiver of the Minimum Liquidity Covenant for the quarter ended December 31, 2022. Without such waiver, we would have been in default of the Convertible Notes, which would have resulted in a cross-default under the Senior Credit Facility. However, we have not obtained a waiver of the Minimum Liquidity Covenant for any future periods, and, as a result of anticipated operating cash outflows from operation, capital investment at our Powered 1 battery factory, and incremental cash payments for the Workforce Restructuring (discussed in Note 15, Subsequent Events), we may not meet the Minimum Liquidity Covenant as of March 31, 2023.
In addition, our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern is an event of default under the Convertible Notes and the Senior Credit Facility. We obtained a prospective limited waiver under the Convertible Notes, which will expire on March 31, 2023, with respect to our obligations under the Convertible Notes to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern in connection with this Annual Report on Form 10-K, and a cross-default under the Convertible Notes with respect to the Senior Secured Credit Facility, resulting from the substantially similar covenant thereunder. If we are unable to obtain a further waiver under the Convertible Notes beyond March 31, 2023, then there would be an event of default under the Convertible Notes for failure to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) in this Annual Report on Form 10-K, which would be a cross-default under the Senior Credit Facility, unless waived. An event of default under the Convertible Notes would permit the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable.
In addition, we have not obtained a waiver with respect to the corresponding covenant under the Senior Credit Facility as of the date hereof and we are therefore in default of such covenant as of the issuance of these financial statements and related audit report. Unless waived, the default under the Senior Credit Facility resulting from the issuance of these financial statements and related audit report containing a going concern qualification (and potential cross-default under the Convertible Notes if we are unable to obtain a waiver thereunder beyond March 31, 2023), permits the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable.
In addition, if we are unable to comply with or obtain a waiver for the Minimum Liquidity Covenant for the quarter ended March 31, 2023 or a future period, there would be an event of default under the Convertible Notes and a cross-default under the Senior Credit Facility for such period, which would permit (i) the holders of
the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable and (ii) the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable.
We are working with the holders of the Convertible Notes and the lenders under the Senior Credit Facility to come to a resolution; but we cannot guarantee a resolution on a timely basis, on favorable terms or at all.
If the Convertible Notes and amounts outstanding under the Senior Credit Facility were to become immediately due and payable in the event of such a default, this would have an immediate adverse effect on our ability to meet our working capital needs and our business and operating results. There is no assurance that we will be able to obtain any future waivers under the Convertible Notes or the Senior Credit Facility. We would need to take further action to raise additional funds in the capital markets or otherwise to fund our obligations under the Convertible Notes in addition to our other obligations over the period, and we would not be able to draw upon the Senior Credit Facility. If we do not have sufficient funds or we are unable to arrange for additional financing to repay outstanding debt, the lenders under the Senior Credit Facility and holders of the Convertible Notes could seek to enforce their security interests in the collateral securing the indebtedness under the Senior Credit Facility and the Convertible Notes, which are secured substantially by all our assets including intellectual property and other restricted property.
Our potential inability to maintain the Liquidity requirement under the Convertible Notes and the current and potential events of default under the Convertible Notes and the Senior Credit Facility when coupled with the following conditions: our available cash resources, recurring losses and cash outflows from operations, an expectation of continuing operating losses and cash outflows from operations for the foreseeable future, and the need to raise additional capital to finance our future operations, causes substantial doubt about our ability to continue as a going concern to exist.
We are currently executing on various strategies to improve available cash balances, liquidity and cash generated from operations that include a workforce reduction across the Company announced in January 2023, and our plan to windup operations at the City of Industry facility by the end of the third quarter of 2023 to improve operational efficiency. We expect to seek additional funds through potential securities financings, debt financings or other capital sources or strategic transactions. In addition, we may seek to obtain a waiver or amendment of our existing debt agreements. However, we may not be successful in securing additional financing on acceptable terms or at all, or in obtaining a waiver or amendment to our existing debt agreements. Furthermore, high volatility and uncertainty in the capital markets resulting from the COVID-19 pandemic and macroeconomic conditions, including rising inflation rates and interest rates, and recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, has had, and could continue to have, a negative impact on the price of our common stock and could adversely impact our ability to raise additional funds. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate some of our business activities, including related operating expenses, which would adversely affect our business prospects and our ability to continue our operations and would have a negative impact on our financial condition and ability to pursue our business strategies. Further, if sufficient funds are not available, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our audited financial statements, and/or seek protection under Chapters 7 or 11 of the United States Bankruptcy Code, and it is likely that investors will lose all or a part of their investment. This could potentially cause us to cease operations and result in a complete loss of your investment in our common stock.
These financial statements have been prepared by management in accordance with GAAP and this basis assumes that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. These financial statements do not include any adjustments that may result from the outcome of this uncertainty.
Senior Credit Facility
In May 2019, we entered into a Loan, Guaranty and Security Agreement (the “Senior Credit Facility”), which is a senior secured asset-based lending facility with borrowing capacity up to $75.0 million. The Senior
Credit Facility is available on a revolving basis through the earlier of May 2024 or 91 days prior to the stated maturity of any subordinated debt in aggregate amount of $7.5 million or more. The maximum availability under the Senior Credit Facility is based on eligible accounts receivable and inventory, subject to certain reserves, determined in accordance with the Senior Credit Facility. The commitment under the Senior Credit Facility includes a $25.0 million letter of credit sub-line, which was increased in January 2023 from $20.0 million as of December 31, 2022. Subject to certain conditions, the commitment may be increased by $50.0 million upon approval by the lender, and at our option, the commitment can be reduced to $25.0 million or terminated upon at least 15 days’ written notice.
The Senior Credit Facility is secured by a security interest on substantially all our assets except for intellectual property and other restricted property.
Borrowings under the Senior Credit Facility bear interest at per annum rates equal to, at our option, either (i) the base rate plus an applicable margin for base rate loan, or (ii) the London Interbank Offered Rate (“LIBOR”), plus an applicable margin for LIBOR loan. The base rate is calculated as the greater of (a) the Lender prime rate, (b) the federal funds rate plus 0.5%, and (c) one-month LIBOR plus 1.0%. The applicable margin is calculated based on a pricing grid linked to quarterly average excess availability (as a percentage of borrowing capacity). For base rate loans, the applicable margin ranges from 0.0% to 1.5%, and for LIBOR Loans, it ranges from 1.5% to 3.0%. The unused line fee is 0.375% per annum of the actual daily amount of the unutilized revolver commitment and will be reduced to 0.25% under certain conditions.
The Senior Credit Facility contains certain customary non-financial covenants. In addition, the Senior Credit Facility requires us to maintain a Fixed Charge Coverage Ratio of at least 1.00:1.00 during such times as a covenant trigger event shall exist.
As of December 31, 2022, there was no balance outstanding under the Senior Credit Facility, although we utilized $17.6 million of the facility’s sub-line for letters of credit.
Small Business Administration Loan
In May 2020, we received Small Business Administration (the “SBA”) loan proceeds of $10.0 million from Town Center Bank pursuant to the Paycheck Protection Program (the “PPP loan”) under the “Coronavirus Aid, Relief and Economic Security (CARES) Act”. The PPP loan was in the form of a note with an original maturity in May 2022, and which was extended to May 2025 based on the SBA’s interim final rule. The interest rate was 1.0% per annum and interest is payable monthly commencing in October 2021. All or a portion of the loan was eligible for forgiveness by the SBA upon application with supporting documentation of expenditures in accordance with the SBA requirements, which include employees being kept on the payroll for eight weeks after the date of the loan and the proceeds being used for payroll, rent, mortgage interest, or utilities.
In May 2022, the SBA approved our PPP loan forgiveness application, and the PPP loan of $10.0 million was forgiven in full and the previously paid interest of approximately $0.2 million was refunded. A total of $10.2 million was recorded as gain on debt extinguishment in our consolidated statements of operations.
Secured Convertible Promissory Notes
In August 2020, we issued the Convertible Notes. The Convertible Notes had an aggregate principal amount of $200.0 million as of the issuance date, with a cash interest of 5.0% per annum payable at each quarter end and a paid-in-kind interest of 4.5% per annum payable by increasing the principal balance at each quarter end. The Convertible Notes will mature in August 2025, and we may not make prepayment unless approved by the required holders of the Convertible Notes.
Each of the Convertible Notes rank equally without preference or priority of any kind over one another, but senior in all rights, privileges, and preferences to all other shares of our capital stock and all other securities that are convertible into or exercisable for our capital stock directly or indirectly.
Prior to the maturity date or conversion of the entire balance of the Convertible Notes, in the event of a liquidation or sale of the Company, we shall pay to the holders of Convertible Notes the greater of (i) 150% of
the principal balance of the Convertible Notes or (ii) the consideration that the holders would have received had the holders elected to convert the Convertible Notes into common stock immediately prior to such liquidation event.
The Convertible Notes do not entitle the holders to any voting rights or other rights as a stockholder of the Company, unless and until the Convertible Notes are actually converted into shares of our capital stock in accordance with their terms.
The Note Purchase Agreement governing the Convertible Notes contains certain customary non-financial covenants. In addition, the Note Purchase Agreement requires us to maintain liquidity at quarter end (“Minimum Liquidity Covenant”) of not less than the greater of (i) $75.0 million and (ii) four times of Cash Burn (as defined therein) for the three-month period then ended.
In connection with the issuance of the Convertible Notes, we issued to the purchasers of the Convertible Notes warrants to purchase 4.6 million shares of our stock at an exercise price of $0.02 per share. These warrants are freestanding financial instruments and, prior to the Closing, were classified as liability due to the possibility that they could become exercisable into Legacy Proterra convertible preferred stock. The warrant liability was remeasured on a recurring basis at each reporting period date, with the change in fair value reported in the statement of operations. Upon any exercise of the warrants for shares of common stock, the carrying amount of the warrant liability was reclassified to stockholders’ equity. Upon the consummation of the Merger, the warrants became exercisable for Proterra common stock, with no possibility to convert to Legacy Proterra convertible preferred stock. As a result, the carrying amount of the warrant liability was reclassified to stockholders’ equity. The loss from change in fair value of the warrant liability was $47.3 million for the year ended December 31, 2021. An aggregate of $69.3 million in warrant liability was reclassified to additional paid-in capital upon exercise and consummation of the Merger. In the fourth quarter of 2021, all remaining outstanding warrants were exercised for shares of common stock.
Prior to the Closing, the embedded features of the Convertible Notes were composed of conversion options that had the economic characteristics of a contingent early redemption feature settled in shares of our stock rather than cash, because the total number of shares of our stock delivered to settle these embedded features would predominantly have a fixed value. These conversion options were bifurcated and accounted for separately from the host debt instrument. The derivative liability of $68.5 million was initially measured at fair value on its issuance date and recorded as a debt discount and was amortized during the term of the Convertible Notes to interest expense using effective interest method. The derivative liability was remeasured on a recurring basis at each reporting period date, with the change in fair value reported in the statement of operations. The loss from the change in fair value of the derivative liability was $111.7 million for the year ended December 31, 2021. Upon the consummation of the Merger, the embedded conversion features associated with the Convertible Notes no longer qualified for derivative accounting since the conversion price became fixed. The $182.6 million carrying amount of the embedded derivative, fair value as of the date of the Closing, was reclassified to stockholders’ equity in accordance with Topic 815, Derivatives and Hedging.
At the Closing, certain Convertible Note holders with an original aggregate principal amount of $46.5 million elected to convert their Convertible Notes at the Closing of the Business Combination, resulting in the issuance of 7.4 million shares of common stock. An aggregate of $48.8 million principal and interest was reclassified to stockholders’ equity, and $21.0 million of remaining related debt issuance costs were expensed to interest expense.
As of December 31, 2022, the outstanding balance of the Convertible Notes was $170.8 million inclusive of PIK interest of $17.3 million.
The remaining Convertible Notes including accrued interest will be automatically converted to common stock at $6.5712 per share pursuant to the mandatory conversion provisions, if and when the VWAP of our common stock exceeds $9.86 over 20 consecutive days.
We were not in compliance with the Minimum Liquidity Covenant in the Convertible Notes as of December 31, 2022, We received a waiver of such Liquidity (as defined therein) requirement in February 2023
which provides for retroactive effect, so that there was no such event of default for the year ended December 31, 2022. Refer to Note 15, Subsequent Events for details.
Due to the uncertainty of obtaining waivers of the Liquidity requirement (as defined therein) for future periods and our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern, even though the Convertible Notes have a maturity date in August 2025, they are classified as a current liability on the Company’s balance sheets as of December 31, 2022.
Performance bonds
Public transit agencies may require their suppliers to obtain performance bonds from surety companies or letters of credit to protect against non-performance. These performance guarantees are normally valid from contract effective date to completion of the contract, which is generally upon customer acceptance of the vehicle. Surety companies limit the maximum coverage they will provide based on financial performance and do not provide committed bonding facilities. Currently, we are required to collateralize a portion of the total performance bond amount. Historically, we have primarily provided cash collateral. Our surety provider may accept letters of credit. The collateral provided is a mix of restricted cash on the balance sheet and letters of credit. As of December 31, 2022, we had $12.6 million of restricted cash and $17 million of letters of credit related to performance bonds. We believe we have sufficient capacity to meet the performance guarantee needs of our business through our arrangements with our primary surety provider.

Operating activities
Net cash used in operating activities in 2022 was $296.6 million compared to $126.3 million in 2021. In both years, the cash used in operating activities was due to net losses and increases in working capital due to the growth of our business, especially the strategic purchases in inventory due to supply chain constraints and higher costs from material and freight inflation. The decrease in net loss of $12.1 million in the year ended December 31, 2022 as compared to the year ended December 31, 2021 included decreases of non-cash items of $70.2 million of loss on change in the fair value of derivative and warrant liabilities, $21.2 million of interest expense and debt discount and issuance costs amortization expense, and partially offset by increase of $5.8 million of stock-based compensation expense. For the year ended December 31, 2022, cash used in operating activities primarily related to $54.5 million,$48.7 million, $35.7 million and $13.5 million for inventory, accounts receivable, prepaid expenses and other current assets and other assets, respectively, and was partially offset by cash provided by deferred revenue and accounts payable and accrued liabilities of $31.0 million and $14.9 million, respectively. For the year ended December 31, 2021, cash used in operating activities primarily related to $29.9 million, $20.2 million, and $8.0 million for accounts receivable, inventory, prepaid expenses and other current assets, respectively, and was partially offset by cash provided by accounts payable and accrued liabilities and deferred revenue of $27.4 million and $6.6 million, respectively.
Net cash used in operating activities in 2021 was $126.3 million compared to $76.1 million in 2020. In both years, the cash used in operating activities was due to net losses and increases in working capital. The increase in net loss of $123.0 million in the year ended December 31, 2021 as compared to the year ended December 31, 2020 included increases of non-cash items of $57.2 million of loss on change in the fair value of
derivative and warrant liabilities, $33.5 million of interest expense and debt discount and issuance costs amortization expense, and $5.8 million of stock-based compensation expense. For the year ended December 31, 2021, cash used in operating activities primarily related to $29.9 million, $20.2 million, and $8.0 million for accounts receivable, inventory, prepaid expenses and other current assets, respectively, and was partially offset by cash provided by accounts payable and accrued liabilities and deferred revenue of $27.4 million and $6.6 million, respectively. For the year ended December 31, 2020, cash used in operating activities primarily related to $7.2 million and $4.1 million for accounts receivable and accounts payable and accrued liabilities, respectively, and was partially offset by cash provided by deferred revenue, inventory, and other non-current liabilities of $9.6 million, $2.2 million, and $2.2 million, respectively.
Investing activities
Net cash provided by investment activities was $184.1 million in the year ended December 31, 2022 compared to net cash used in investment activities $447.3 million in the year ended December 31, 2021. The $631.4 million change was primarily driven by a net increase of $667.4 million related to more proceeds from maturity of investments in the year ended December 31, 2022 as compared to more purchases of investments in the year ended December 31, 2021, and a $36.0 million increase in capital expenditures.
Net cash used in investment activities was $447.3 million in the year ended December 31, 2021 compared to $54.5 million in the year ended December 31, 2020. The $392.8 million change was primarily driven by a net increase of $394.9 million related to the purchase of investments in the year ended December 31, 2021 as compared to the year ended December 31, 2020, and a $2.1 million increase in capital expenditures. The increased purchase of investments was driven by our investment of the net proceeds from the Business Combination.
Financing activities
Net cash provided by financing activities was $16.2 million, $632.4 million, and $200.6 million for the years ended December 31, 2022, 2021 and 2020, respectively. The net cash provided by financing activities for the year ended December 31, 2022 primarily resulted from net proceeds of $9.8 million from the exercise of stock options and warrants, and $3.0 million from the ESPP. The net cash provided by financing activities for the year ended December 31, 2021 primarily resulted from net proceeds of $644.7 million from the Business Combination and the PIPE Financing and $6.8 million from the exercise of stock options and warrants, which was partially offset by a Senior Credit Facility repayment of $17.1 million. The net cash provided by financing activities for the year ended December 31, 2020 primarily resulted from proceeds from borrowings of $200.0 million through the issuance of Convertible Notes, $14.5 million under the Senior Credit Facility, $10.0 million from PPP loan, and $4.2 million from the exercise of stock options, offset by $12.8 million repayment under the Senior Credit Facility and $10.0 million repayment of a prior credit facility with Hercules Capital, Inc.
Off-balance sheet arrangements
We have not created, and are not party to, any special-purpose or off-balance sheet entities for the purpose of raising capital, incurring debt, or operating our business. With the exception of letters of credit, we do not have any off-balance sheet arrangements or relationships with entities that are not disclosed in our consolidated financial statements that have, or are reasonably likely to have, a material current or future effect on our financial condition, revenue, expenses, results of operations, liquidity, capital expenditures, or capital resources. In addition, we do not engage in trading activities involving non-exchange traded contracts.
Contractual obligations
The purchase commitments including purchase orders or contracts for the purchase of certain goods and services was $2.2 billion as of December 31, 2022, of which approximately 20% was expected to be due within one year, 37% in 2024 and 2025, and the remainder thereafter through 2028. Most of the commitments relate to the expected purchase of cylindrical cells manufactured at a yet to be built LG Energy Solution battery cell plant in the United States, pursuant to a long-term supply agreement through 2028.
The Convertible Notes had an outstanding principal amount inclusive of PIK interest of $170.8 million as of December 31, 2022, which will mature in August 2025. The outstanding balances will be automatically converted into common stock at $6.5712 per share pursuant to the mandatory conversion provisions, if and when the VWAP of our common stock exceeds $9.86 over 20 consecutive days.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risks in the ordinary course of our business.
Interest rate and market risk
As of December 31, 2022, we had cash and cash equivalents and short-term investments of $298.1 million. Our cash and cash equivalents and short-term investments are held primarily in U.S. treasury and corporate debt securities, and money market funds. Our primary objectives for investment activities are to preserve principal, provide liquidity, and maximize income without significantly increasing risk.
Our investments in fixed rate debt securities are subject to market risk due to changes in interest rates. our future investment income may fluctuate due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. Our debt securities are classified as “available for sale.” When the fair value of the security declines below its amortized cost basis, any portion of that decline attributable to credit losses, to the extent expected to be nonrecoverable before the sale of the security, is recognized in our consolidated statement of operations. When the fair value of the security declines below its amortized cost basis due to changes in interest rates, such amounts are recorded in other comprehensive loss, and are recognized in our consolidated statement of operations only if we sell or intend to sell the security before recovery of its cost basis.
Based on a sensitivity model that measures market value changes when changes in interest rates occur, as of December 31, 2022, an immediate increase of 100-basis points in interest rates would have no material impact to the fair value of our cash equivalents and short-term investment.
We had non-controlling equity investments in privately-held companies of $26.6 million as of December 31, 2022. The fair value of such strategic investment may fluctuate depending on the financial condition and near-term prospects of these companies, and we may be required to record an impairment loss if the carrying value of the investment exceed its fair value.
We are exposed to interest rate risk related to our indebtedness under the Senior Credit Facility that bears interest at floating rates based on the prime rate plus a specified margin. As of December 31, 2022, we had no borrowing outstanding under the Senior Credit Facility.
Foreign currency exchange rate risk
We are exposed to foreign currency exchange rate risk, primarily related to certain raw material purchases denominated in Euros and certain accounts receivables from three customers denominated in Canadian dollars. Payments denominated in foreign currencies represented less than 5% of our total payments during the years ended December 31, 2022, 2021 and 2020. The revenue from the customers with accounts receivable denominated in Canadian dollars was less than 1% of our total revenue for the years ended December 31, 2022 and 2021, and was less than 10% of our total revenue for the year ended December 31, 2020. The exchange rate fluctuations were not material in the years ended December 31, 2022 and 2021, and accounted for $1.1 million of other expense in the year ended December 31, 2020. The higher expense in 2020 was mainly due to foreign exchange rate fluctuations in the first half of 2020. As a result, we believe that we currently do not have material exposure to changes in foreign currency exchange rates.
Inflation Risk
Volatility in the prices of commodities and third-party parts and components or the impact of inflationary increases could increase the costs of our products and services. We may not be able to pass on these costs to our customers and this could have a material adverse impact on our results of operations and cash flows. The reasons for these fluctuations include the impact by global supply and demand trends, both within and outside our industry, as well as commodity price fluctuations, conversion costs, energy costs, labor costs, and transportation costs, competition, worldwide currency fluctuations, regulatory costs, and product and process evolutions that impact demand for the same materials. We have experienced inflation in our material costs, including increased costs for freight, due to supply chain challenges as a result of COVID-19.

To the Stockholders and Board of Directors
Proterra Inc:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Proterra Inc and subsidiary (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 17, 2023 expressed an adverse opinion on the effectiveness of the Company’s internal control over financial reporting.
Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company’s projected noncompliance with liquidity requirements related to the Convertible Notes, combined with a history and expectation of continued recurring losses and cash outflows from operations for the foreseeable future raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit
matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Product warranty reserve
As discussed in Note 1 to the consolidated financial statements, the Company’s product warranty reserve as of December 31, 2022 was $25.5 million, including a warranty reserve on vehicles sold to customers. The Company records a warranty reserve for vehicles sold at the point of revenue recognition, which includes management’s best estimate of the projected costs to repair or replace items under the limited warranty and field service actions. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims.
We identified the evaluation of the product warranty reserve related to the sale of vehicles as a critical audit matter. Specifically, a high degree of subjective auditor judgment was required to evaluate the Company’s estimate of the total warranty cost per vehicle due to the relatively short period of the Company’s historical warranty claim experience and lack of relevant industry data for warranty costs. In addition, changes in the total warranty cost per vehicle could have had a significant effect on the estimate of the warranty reserve.
The following are the primary procedures we performed to address this critical audit matter. We assessed the estimated future warranty repair costs used in the development of the total warranty cost per vehicle by comparing them to the Company’s historical warranty claims data. We tested a sample of the current year claims used in the determination of the estimated future warranty repair costs by comparing them to the relevant underlying documentation. We also assessed the consistency of the Company’s warranty reserve with recent trends in actual warranty claims, taking into account changes in conditions affecting the Company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Stockholders and Board of Directors
Proterra Inc:
Opinion on Internal Control Over Financial Reporting
We have audited Proterra Inc and subsidiary's (the Company) internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weaknesses, described below, on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive loss, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2022, and the related notes (collectively, the consolidated financial statements), and our report dated March 17, 2023 expressed an unqualified opinion on those consolidated financial statements.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment. The Company did not have a sufficient number of trained resources with assigned responsibility and accountability for the design, operation and documentation of internal control over financial reporting. As a result:
•The Company did not have an effective risk assessment process that defined clear financial reporting objectives and evaluated risks at a sufficient level of detail to identify all relevant risks of material misstatement across the entity;
•The Company did not have an effective information and communication process that identified and assessed the source of and controls necessary to ensure the reliability of information used in financial reporting and that communicates relevant information about roles and responsibilities for internal control over financial reporting;
•The Company did not have effective monitoring activities to assess the operation of internal control over financial reporting, including the continued appropriateness of control design and level of documentation maintained to support control effectiveness.
As a consequence, the Company did not effectively design, implement, or operate process-level control activities for substantially all of the Company’s financial reporting processes.
The material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2022 consolidated financial statements, and this report does not affect our report on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Organization and Description of Business
Proterra Inc (“Proterra” or the “Company"), formerly known as ArcLight Clean Transition Corp. (“ArcLight”), is a leading developer and producer of zero-emission electric vehicle and EV technology solutions for commercial application. Proterra designs, develops, manufactures, and sells electric transit buses as an original equipment manufacturer for North American public transit agencies, airports, universities, and other commercial transit fleets. It also designs, develops, manufactures, sells, and integrates proprietary battery systems and electrification solutions for global commercial vehicle manufacturers. Additionally, Proterra provides fleet-scale, high-power charging solutions for its customers.
Legacy Proterra (as defined below) was originally formed in June 2004 as a Colorado limited liability company and converted to a Delaware corporation in February 2010. Proterra is headquartered in Burlingame, California, and also has manufacturing and product development facilities in Burlingame and City of Industry, California, and Greenville and Greer, South Carolina.
On June 11, 2021, ArcLight filed a notice of deregistration with the Cayman Islands Registrar of Companies, and filed a certificate of incorporation and a certificate of corporate domestication with the Secretary of State of the State of Delaware, under which ArcLight was domesticated and continued as a Delaware corporation. On June 14, 2021 (the “Closing Date”), ArcLight consummated a merger with Phoenix Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of ArcLight (“Phoenix Merger Sub”), and Proterra Inc, a Delaware corporation (“Legacy Proterra”), with Legacy Proterra surviving as the surviving company and as a wholly-owned subsidiary of ArcLight (the “Merger” and, collectively with the other transactions described in the Agreement and Plan of Merger (the “Merger Agreement”), the “Business Combination”). In connection with the Business Combination, Legacy Proterra changed its name to “Proterra Operating Company, Inc.” and ArcLight changed its name to “Proterra Inc”.
The Merger was accounted for as a reverse merger and a recapitalization with Legacy Proterra being the accounting acquirer. Accordingly, all historical financial information presented in the consolidated financial statements of Proterra represents the accounts of Legacy Proterra and its wholly owned subsidiaries as if Legacy Proterra is the predecessor to Proterra. The shares and net loss per common share, prior to the Merger, have been retroactively restated as shares reflecting the exchange ratio established in the Merger (0.8925 shares of Legacy Proterra common stock for 1 share of Proterra common stock) (the “Exchange Ratio”). Unless otherwise specified or unless the context otherwise requires, references in these notes to the “Company,” “we,” “us,” or “our” refer to Legacy Proterra prior to the Business Combination and to Proterra following the Business Combination.
Prior to the closing of the Business Combination (the “Closing”), ArcLight’s Class A ordinary shares and public warrants were listed on the Nasdaq Capital Market under the symbols “ACTC” and “ACTCW,” respectively. Proterra’s common stock is currently listed on the Nasdaq Global Select Market under the symbol “PTRA”. See Note 3, “Reverse Recapitalization” for further details of the Merger. The Company’s public warrants were previously listed on the Nasdaq Global Select Market under the symbol “PTRAW.” On October 29, 2021, the Company redeemed its remaining outstanding public warrants at a redemption price of $0.10 per public warrant. See Note 10, Warrants, for further details.
The Company has incurred net losses and negative cash flows from operations since inception. As of December 31, 2022, the Company has an accumulated deficit of $1.1 billion, and cash and cash equivalents and short-term investments of $298.1 million. The Company has funded operations primarily through a combination of equity and debt financing. There was no outstanding balance under the Senior Credit Facility as of December 31, 2022. There was an aggregate of $17.6 million of letters of credit outstanding as of December 31, 2022. As of December 31, 2022, the outstanding balance of the Convertible Notes was $170.8 million inclusive of PIK interest of $17.3 million.

1. Summary of Significant Accounting Policies (cont.)
Under ASC Subtopic 205-40, Presentation of Financial Statements-Going Concern (“ASC 205-40”), we have the responsibility to evaluate whether conditions and/or events raise substantial doubt about our ability to meet our future financial obligations as they become due within one year of the financial statements being issued.
Pursuant to the terms of the purchase agreement governing the Convertible Notes, we are required to maintain Liquidity (as defined therein) as of the last day of each quarter of not less than the greater of (a) $75.0 million and (b) an amount equal to the product of multiplying (i) the amount of Cash Burn (as defined therein) from operations for the three-month period ending on the end of such month by (ii) four (the “Minimum Liquidity Covenant”).
As of December 31, 2022, we did not have Liquidity in an amount equal to clause (b) above as of such date. As a result, we obtained a waiver of the Minimum Liquidity Covenant for the quarter ended December 31, 2022. Without such waiver, we would have been in default of the Convertible Notes, which would have resulted in a cross-default under the Senior Credit Facility. However, we have not obtained a waiver of the Minimum Liquidity Covenant for any future periods, and, as a result of anticipated operating cash outflows from operation, capital investment at our Powered 1 battery factory, and incremental cash payments for the Workforce Restructuring (discussed in Note 15, Subsequent Events), we may not meet the Minimum Liquidity Covenant as of March 31, 2023.
In addition, our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern is an event of default under the Convertible Notes and the Senior Credit Facility.
We obtained a prospective limited waiver under the Convertible Notes, which will expire on March 31, 2023, with respect to our obligations under the Convertible Notes to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern, and a cross-default under the Convertible Notes with respect to the Senior Secured Credit Facility, resulting from the substantially similar covenant thereunder. If we are unable to obtain a further waiver under the Convertible Notes beyond March 31, 2023, then there would be an event of default under the Convertible Notes for failure to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation), which would be a cross-default under the Senior Credit Facility, unless waived. An event of default under the Convertible Notes would permit the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable.
In addition, we have not obtained a waiver with respect to the corresponding covenant under the Senior Credit Facility as of the date hereof and we are therefore in default of such covenant as of the issuance of these financial statements and related audit report. Unless waived, the default under the Senior Credit Facility resulting from the issuance of these financial statements and related audit report containing a going concern qualification (and potential cross-default under the Convertible Notes if we are unable to obtain a waiver thereunder beyond March 31, 2023), permits the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable.
In addition, if we are unable to comply with or obtain a waiver for the Minimum Liquidity Covenant for the quarter ended March 31, 2023 or a future period, there would be an event of default under the Convertible Notes and a cross-default under the Senior Credit Facility for such period, which would permit (i) the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable and (ii) the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable.
If the Convertible Notes and amounts outstanding under the Senior Credit Facility were to become immediately due and payable in the event of such a default, this would have an immediate adverse effect on our ability to meet our working capital needs and our business and operating results. There is no assurance that we
PROTERRA INC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Summary of Significant Accounting Policies (cont.)
will be able to obtain any future waivers under the Convertible Notes or the Senior Credit Facility. We would need to take further action to raise additional funds in the capital markets or otherwise to fund our obligations under the Convertible Notes in addition to our other obligations over the period, and we would not be able to draw upon the Senior Credit Facility. If we do not have sufficient funds or we are unable to arrange for additional financing to repay outstanding debt, the lenders under the Senior Credit Facility and holders of the Convertible Notes could seek to enforce their security interests in the collateral securing the indebtedness under the Senior Credit Facility and the Convertible Notes, which are secured substantially by all our assets including intellectual property and other restricted property.
Our potential inability to maintain the Liquidity requirement under the Convertible Notes and the current and potential events of default under the Convertible Notes and the Senior Credit Facility when coupled with the following conditions: our available cash resources, recurring losses and cash outflows from operations, an expectation of continuing operating losses and cash outflows from operations for the foreseeable future, and the need to raise additional capital to finance our future operations, causes substantial doubt about our ability to continue as a going concern to exist.
We are currently executing on various strategies to improve available cash balances, liquidity and cash generated from operations that include a workforce reduction across the Company announced in January 2023, and our plan to windup operations at the City of Industry facility by the end of the third quarter of 2023 to improve operational efficiency. We expect to seek additional funds through potential securities financings, debt financings or other capital sources or strategic transactions. In addition, we may seek to obtain a waiver or amendment of our existing debt agreements. However, we may not be successful in securing additional financing on acceptable terms or at all, or in obtaining a waiver or amendment to our existing debt agreements. Furthermore, high volatility and uncertainty in the capital markets resulting from the COVID-19 pandemic and macroeconomic conditions, including rising inflation rates and interest rates, and recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, has had, and could continue to have, a negative impact on the price of our common stock and could adversely impact our ability to raise additional funds. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate some of our business activities, including related operating expenses, which would adversely affect our business prospects and our ability to continue our operations and would have a negative impact on our financial condition and ability to pursue our business strategies.
These financial statements have been prepared by management in accordance with GAAP and this basis assumes that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. These financial statements do not include any adjustments that may result from the outcome of this uncertainty.
Basis of Presentation
The consolidated financial statements and accompanying notes have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”). The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated upon consolidation.
The Company has not experienced any significant impact to estimates or assumptions as a result of the COVID-19 pandemic. However, the Company’s financial results have been impacted by ongoing constraints and inefficiencies in production largely driven by shortages of component parts and shipment delays, and workforce absences due to illness or quarantines during the pandemic experienced by the Company or its suppliers. While the COVID-19 pandemic has not had a material adverse impact on the Company’s financial condition and results of operations to date, the related global supply chain interruption, macroeconomic and geopolitical conditions on the Company’s future operational and financial performance will depend on certain developments, including the impact on the Company’s customers and the effect on the Company’s suppliers, all of which are uncertain and cannot be predicted.

The Company operates in the United States and has sales to the European Union, Canada, United Kingdom, Australia, Japan and Türkiye. Revenue disaggregated by geography, based on the addresses of the Company’s customers, consists of the following (in thousands):

Total $ 309,364 $ 242,860 $ 196,943
The Company’s chief operating decision maker is its Chief Executive Officer (CEO) who reviews financial information presented on a consolidated basis for purposes of making decision on allocating resources and assessing financial performance. Accordingly, the Company has determined that it has a single reportable segment.
Use of Estimates
The preparation of financial statements in conformity with U.S. GAAP requires the use of estimates and judgments that affect the reported amounts in the consolidated financial statements and accompanying notes. U.S. GAAP requires the Company to make estimates and judgments in several areas including, but not limited to, those related to revenue recognition, collectability of accounts receivable, valuation of inventories, valuation of Convertible Notes (See Note 4), warranty liability, contingent liabilities, stock-based compensation expense, useful lives of property, plant, and equipment, recoverability of assets, residual value of leased assets, and the valuation of deferred tax assets. These estimates are based on historical facts and various other assumptions that the Company believes are reasonable. Actual results could differ materially from those estimates.
Foreign Currency Transactions
The U.S. dollar is the Company’s functional currency. Monetary assets and liabilities denominated in currencies other than the U.S. dollar are remeasured to the U.S. dollar at period end, and transaction gains and losses are recorded in other expense (income), net in the statements of operations. Net gains or losses resulting from foreign exchange transactions was not material for the years ended December 31, 2022 and 2021. The net losses resulting from foreign exchange transactions were $1.1 million for the year ended December 31, 2020.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company determines the allowance for credit losses based on historical write-off experience, an analysis of the aging of outstanding receivables, customer payment patterns and expectations of changes in macroeconomic conditions that may affect the collectability of outstanding receivables. The allowance for credit losses was not material as of December 31, 2022 and 2021.
Short-Term Investments
The Company’s primary objectives for investment activities are to preserve principal, provide liquidity, and maximize income without significantly increasing risk. The Company’s short-term investments were primarily

1. Summary of Significant Accounting Policies (cont.)
comprised of U.S. Treasury and corporate debt securities, and classified as available-for-sale at the time of purchase because it is intended that these investments are available for current operations.
Investments are reported at fair value and are subject to periodic impairment review. Unrealized gains and losses related to changes in the fair value of these securities are recognized in accumulated other comprehensive loss. The ultimate value realized on these securities is subject to market price volatility until they are sold. Realized gains or losses from short-term investments are recorded in other expense (income), net.
As of December 31, 2022 and 2021, short-term investments were $224.4 million and $491.0 million, respectively.
Restricted Cash
The Company maintains certain cash amounts restricted as to withdrawal or use. The restricted cash is primarily collateral for performance bonds issued to certain customers. The collateral is provided in the form of a cash deposit to either support the bond directly or to collateralize a letter of credit that supports the performance bonds. The restricted cash was $12.6 million as of December 31, 2022 and 2021.
Credit Risk and Concentration
The Company’s financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, restricted cash, short-term investments, and accounts receivable. Cash and cash equivalents and short-term investments are maintained primarily at one financial institution as of December 31, 2022, and deposits exceed federally insured limits. Risks associated with cash and cash equivalents, and short-term investments are mitigated by banking with creditworthy financial institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents or its short-term investments.
Cash equivalents and short-term investments consist of short-term money market funds, corporate debt securities, and debt securities issued by the U.S. Treasury, which are deposited with reputable financial institutions. The Company’s cash management and investment policy limits investment instruments to securities with short-term credit ratings at the time of purchase of P-2 and A-2 or better from Moody’s Investors Service and Standard & Poor’s Financial Services, LLC, respectively, with the objective to preserve capital and to maintain liquidity until the funds can be used in business operations.
Accounts receivable are typically unsecured and are generally derived from revenue earned from transit agencies, universities and airports in North America and global commercial vehicle manufacturers in North America, the European Union, the United Kingdom, Australia, Japan, and Türkiye. The Company periodically evaluates the collectability of its accounts receivable and provides an allowance for potential credit losses as necessary.
Given the large order value for customers and the relatively low number of customers, revenue and accounts receivable have typically been concentrated with a limited number of customers.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Summary of Significant Accounting Policies (cont.)
Composites Inc. In other instances, although there may be multiple suppliers available, many of the components are purchased from one single source. If these single source suppliers fail to meet the Company’s requirements on a timely basis at competitive prices or are unable to provide components for any reason, the Company could suffer manufacturing delays, a possible loss of revenue, or incur higher cost of sales, any of which could adversely impact the Company’s operating results.
Fair Value of Financial Instruments
The carrying value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, short-term investments, accounts payable, and accrued and other current liabilities, approximates fair value due to the short period of time to maturity, receipt, or payment. The carrying amount of the Company’s debt, except for Convertible Notes (as defined below), approximates its fair value as the stated interest rates approximate market rates currently available to the Company.
In August 2020, the Company issued Secured Convertible Promissory Notes (the “Convertible Notes”) that, prior to the Closing, contained embedded features subject to derivative accounting. These embedded features were composed of conversion options that had the economic characteristics of a contingent early redemption feature settled in a variable number of shares of the Company’s stock. These conversion options were bifurcated and accounted for as a derivative liability separately from the host debt instrument. Embedded derivatives were recognized as a derivative liability on the balance sheets. The derivative liability was measured at fair value and subject to remeasurement at each balance sheet date. Upon the consummation of the Merger, the embedded conversion features associated with the Convertible Notes no longer qualify for derivative accounting after the conversion price became fixed. The carrying amount of the embedded derivative, the fair value as of the date of the Closing, was reclassified to stockholders’ equity in accordance with Topic 815, Derivatives and Hedging.
The warrants issued in connection with the Convertible Notes were, prior to the Closing, classified as a liability (“legacy Proterra warrant liability”) because they could become exercisable into common stock upon a Qualified Initial Public Offering (“QIPO”) or into convertible preferred stock after 5 years from issuance date in the event that there is no QIPO during such period. Such warrants were measured at fair value, subject to remeasurement at each balance sheet date. Upon exercise of the warrants to common stock within 5 years from issuance date, the carrying amount of the warrant liability would be reclassified to stockholders’ equity. Upon the consummation of the Merger, the stock issuable upon exercise of the warrants is common stock, with no possibility to convert to Legacy Proterra convertible preferred stock. As a result, the carrying amount of the warrant liability was reclassified to stockholders’ equity.
In connection with ArcLight’s initial public offering in September 2020, 21,425,000 warrants to purchase ArcLight ordinary shares were issued, including 13,875,000 public warrants and 7,550,000 private placement warrants. These warrants were classified as liabilities as they did not meet the requirements for equity classification under Topic 815, Derivatives and Hedging. These warrants were continually measured at fair value, subject to remeasurement at each balance sheet date. Most of the public warrants and private placement warrants were exercised in October 2021, and the Company redeemed the remaining outstanding public warrants at a redemption price of $0.10 per public warrant. See Note 10, Warrants, for further details.
Inventories
Inventories are recorded at the lower of cost and net realizable value using the first-in, first-out method. Inventory costs consist primarily of the cost of materials, manufacturing support costs, including labor and factory overhead associated with such production, and shipping costs. The costs of products delivered to customers that have not yet met revenue recognition criteria are also included in inventories. The Company assesses the valuation of inventory and periodically records a provision to adjust inventory to its estimated net realizable value, including when the Company determines inventory to be obsolete or in excess of anticipated demand. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up. Accelerating the disposal process or incorrect estimates may cause actual results to differ from the estimates at the time such inventory is disposed or sold.
PROTERRA INC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Summary of Significant Accounting Policies (cont.)
Deferred Cost of Goods Sold
Deferred cost of goods sold primarily includes incurred costs for charging system installations that have not met revenue recognition criteria.
Property, Plant, and Equipment
Property, plant, and equipment, including leasehold improvements, are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets, as follows:
Property, Plant, and Equipment Estimated Useful Life
Computer hardware 3 years
Computer software 3 to 5 years
Internally used vehicles and charging systems over the shorter of their estimated useful lives or 5 years
Machinery and equipment 5 to 12 years
Office furniture and equipment 5 years
Tooling 3 to 5 years
Leasehold improvements over the shorter of their estimated useful lives or the terms of the related leases
Leased batteries over the shorter of the terms of the related leases or 12 years
Leased vehicles and charging systems over the shorter of the terms of the related leases or 5 years
If the estimated useful life of an asset is less than the stated number of years in our capitalization policy, the depreciation expense will be recorded over the shorter period.
Upon the retirement or sale of property, plant, and equipment, the cost and associated accumulated depreciation are removed from the balance sheets, and the resulting gain or loss is reflected on the statement of operations. Maintenance and repair expenditures are expensed as incurred while major improvements that increase the functionality, output, or expected life of an asset are capitalized and depreciated ratably over the identified useful life.
Impairment of Long-Lived Assets
The Company evaluates the recoverability of property, plant, and equipment and right-of-use assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of long-lived assets is not recoverable, the carrying amount of such assets is reduced to fair value.
In addition to the recoverability assessment, the Company periodically reviews the remaining estimated useful lives of property, plant, and equipment. If the estimated useful life assumption for any asset is reduced, the remaining net book value is depreciated over the revised estimated useful life.
No impairment charge was recognized in the years ended December 31, 2022 and 2021. The Company recorded a $0.1 million impairment charge associated with a facility lease for the year ended December 31, 2020.
Deferred Revenue
PROTERRA INC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. Summary of Significant Accounting Policies (cont.)
Deferred revenue consists of billings or payments received in advance of revenue recognition that are recognized as revenue once the revenue recognition criteria are met. In some instances, progress billings are issued upon meeting certain milestones stated in the contracts. Accordingly, the deferred revenue balance does not represent the total contract value of non-cancelable arrangements. Invoices are typically due within 30 to 40 days.
The changes in deferred revenue consisted of the following (in thousands):
Deferred revenue as of December 31, 2021
$ 36,406
Revenue recognized from beginning balance during the year ended December 31, 2022
(13,071)
Deferred revenue added during the year ended December 31, 2022
44,063
Deferred revenue as of December 31, 2022
$ 67,398
The current portion of deferred revenue represents the amount that is expected to be recognized as revenue within one year from the balance sheet date.
Revenue Recognition
The Company derives revenue primarily from the sale of vehicles and charging systems, the installation of charging systems, the sale of battery systems and powertrain components to other vehicle manufacturers, as well as the sale of spare parts and other services provided to customers. Product revenue consists of revenue earned from vehicles and charging systems, battery systems and powertrain components, installation of charging systems, and revenue from leased vehicles, charging systems, and batteries under operating leases. Leasing revenue recognized over time was approximately $1.1 million, $2.1 million and $2.3 million for the years ended December 31, 2022, 2021 and 2020, respectively. Parts and other service revenue includes revenue earned from spare parts, the design and development of battery systems and powertrain systems for other vehicle manufacturers, and extended warranties.
Goods and services that are promised in the Company’s contracts include vehicles, charging systems, battery systems and powertrain components to other vehicle manufacturers, installation of charging systems, spare parts, and extended warranty. The Company assesses the products and services promised in contracts at contract inception, and identifies performance obligations for each promise to transfer to the customer a product or service that is distinct. If a product or service is separately identifiable from other items in the bundled arrangement and a customer can benefit from the product or service on its own or with other resources that are readily available to the customer, then such product or service is considered distinct. Customer contracts typically have multiple performance obligations. Generally, the Company’s goods and services are considered separate performance obligations. Development services and products sold to other vehicle manufacturers are typically sold on a stand-alone basis and are not bundled with other goods or services.
The transaction price of the contract is allocated to each performance obligation in a manner depicting the amount of consideration to which the Company expects to be entitled in exchange for transferring the goods or services to the customer (the “allocation objective”). If the allocation objective is met at contractual prices, no further allocations are made. Otherwise, the Company allocates the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis.
To determine the standalone selling price of its promised products or services, the Company conducts an analysis to determine whether its products or services have an observable standalone selling price. In determining the observable standalone selling price, the Company requires that a substantial majority of the standalone selling prices for a product or service fall within a reasonably narrow range. If there is no directly observable standalone selling price for a particular product or service, then the Company estimates a standalone selling price by using the estimated cost plus margin or by reviewing external and internal market factors including, but not limited to, pricing practices including historical discounting, major service groups, and the geographies in which we offer products and services.

1. Summary of Significant Accounting Policies (cont.)
The Company recognizes revenue when or as it satisfies a performance obligation by transferring control of a product or service to a customer. Revenue from product sales is recognized when control of the underlying performance obligations is transferred to the customer. Revenue from sales of vehicles is typically recognized upon delivery when the Company can objectively demonstrate that the criteria specified in the contractual acceptance provisions are achieved prior to delivery. In cases, where the Company cannot objectively demonstrate that the criteria specified in the contractual acceptance provisions have been achieved prior delivery, revenue is recognized upon acceptance by the customer. Revenue from sales of charging systems is recognized at a point in time, generally upon delivery or commissioning when control of the underlying performance obligations are transferred to the customer. Under certain contract arrangements, the control of the performance obligations related to the charging systems is transferred over time, and the associated revenue is recognized over the installation period using an input measure based on costs incurred to date relative to total estimated costs to completion. Spare parts revenue is recognized upon shipment. Extended warranty revenue is recognized over the life of the extended warranty using the time elapsed method. Development service contracts typically include the delivery of prototype products to customers. The performance obligation associated with the development of prototype products as well as battery systems and powertrain components to other vehicle manufacturers, is satisfied at a point in time, typically upon shipping.
Revenue derived from performance obligations satisfied over time from charging systems and installation was $7.7 million, $5.8 million and $6.0 million in the years ended December 31, 2022, 2021, and 2020, respectively. Extended warranty revenue was $2.1 million, $1.7 million and $1.3 million in the years ended December 31, 2022, 2021, and 2020, respectively.
As of December 31, 2022 and 2021, the contract assets balance was $26.1 million and $1.3 million, respectively, and are recorded in the prepaid expenses and other current assets on the consolidated balance sheets. The contract assets are assessed based on contractual terms and expected to be billed within the next twelve months. The increase was mainly related to two customers, which accounts for 60% and 13% of the balance as of December 31, 2022, respectively.
As of December 31, 2022, the amount of remaining performance obligations that have not been recognized as revenue was $438.7 million, of which 77% was expected to be recognized as revenue over the next 12 months and the remainder thereafter. This amount excludes the value of remaining performance obligations for contracts with an original expected length of one year or less.
The Company has three commercial offerings each addressing a critical component of commercial vehicle electrification.
•Proterra Transit designs, develops, manufactures, and sells electric transit buses as an original equipment manufacturer (“OEM”) for North American public transit agencies, airports, universities, and other commercial transit fleets.

Lease Arrangements
The Company offers customers leasing alternatives outside of the standard sales contracts for vehicles, charging equipment and batteries used in the vehicles. The leasing arrangements are typically bundled together with the sales contracts. The Company assessed the nature of the bundled arrangements under the revenue accounting standard. For arrangements that contain a lease, the Company determined the classification of the lease in accordance with Topic 842, Leases. A lease arrangement that transfers substantially all of the benefits and risks incident to ownership of the products is classified as a sales-type lease based on the criteria established by the accounting standard; otherwise the lease is classified as an operating lease.
For sales-type leases, product revenue is generally recognized upon customer acceptance of the underlying leased assets. The current portion of net investment in sales-type leases is recorded in accounts receivable, and the non-current portion is recorded in other assets on the balance sheets. The discounted unguaranteed residual value of underlying leased assets is not material to the net investment in lease balance.
For operating leases, the leasing revenue is recognized on a straight-line basis over the lease term.
The Company monitors the performance of customers who leased batteries and are subject to ongoing payments. No allowance has been recorded for the receivables under the leasing arrangements.
The Company determines whether an arrangement is or contains a lease at inception. Short-term leases with a term of less than 12 months will not be recognized in the right-of-use assets or lease liabilities. The lease and non-lease components are not separated for all leases regardless of whether the Company is the lessee or a lessor to the lease. See Note 7, Leases, for additional information.
Cost of Goods Sold
Cost of goods sold includes direct material and labor costs, manufacturing overhead including depreciation expense, freight costs, and reserves for estimated warranty expenses. Cost of goods sold also includes charges to write-down the carrying value of inventory when it exceeds its estimated net realizable value and to provide for on-hand inventory that is either obsolete or in excess of forecasted demand. Costs of development services are expensed as incurred. Costs of development services incurred in periods prior to the finalization of a service agreement with a customer are recorded as research and development expense. Once the customer agreement is finalized, these costs are recorded in cost of goods sold.
Sales and Other Taxes
Taxes assessed by various government entities, such as sales, use, and value added taxes, collected at the time of sale are excluded from revenue.
Shipping Costs
Amounts billed to customers related to shipping and handling are classified as revenue, and the related shipping and handling costs are included in cost of goods sold.
Research and Development Costs
Research and development costs are expensed as incurred. Research and development expense consists primarily of payroll and benefits of those employees engaged in research, design, and development activities, costs related to prototype parts and design tools, license expenses related to intellectual property, supplies and services, depreciation, and other occupancy costs.

Advertising Expenses
Advertising costs are expensed as incurred. Advertising expenses were $1.2 million, $1.1 million, and $0.6 million for the years ended December 31, 2022, 2021 and 2020, respectively.
Product Warranties
The Company provides a limited warranty to customers on vehicles, charging systems, and battery systems. The limited warranty ranges from one to 12 years depending on the components. Separately, the Company also periodically performs field service actions related to product service campaigns. Pursuant to these warranties and field service actions, the Company will repair, replace, or adjust the parts on the products that are defective in factory-supplied materials or workmanship. The Company records a warranty reserve for the products sold at the point of revenue recognition, which includes the best estimate of the projected costs to repair or replace items under the limited warranty and field service actions. These estimates are based on actual claims incurred to date and an estimate of the nature, frequency and costs of future claims. These estimates are inherently uncertain given the relatively short history of sales. Changes to the historical or projected warranty experience may cause material changes to the warranty reserve in the future. The warranty reserve does not include projected warranty costs associated with the vehicles under operating leases, as the costs to repair these warranty claims are expensed as incurred. The portion of the warranty reserve expected to be incurred within the next 12 months is included within accrued liabilities while the remaining balance is included within other long-term liabilities on the balance sheets.
Warranty expense is recorded as a component of cost of goods sold. Accrued warranty activity consisted of the following (in thousands):
Year Ended December 31,
2022 2021 2020
Warranty reserve - beginning of period $ 23,274 $ 18,582 $ 14,926

Provision for warranty 14,505 13,601 11,262
Warranty reserve - end of period $ 25,513 $ 23,274 $ 18,582
Stock-Based Compensation
The Company uses the fair value method for recording stock-based compensation expense. Stock-based compensation expense for stock options is estimated at the grant date based on each stock option’s fair value as calculated using the Black-Scholes option pricing model. The stock-based compensation expense is recognized on a straight-line basis over the requisite service period for the entire award.
Income Taxes
Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.
The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Company adjusts these reserves when facts and circumstances change, such as the closing of a tax audit or

the refinement of an estimate. The provision for income taxes includes the effects of any reserves that are considered appropriate.
Accrued interest and penalties related to unrecognized tax benefits are classified as income tax expense.
Government Incentives
The Company receives incentives from federal and state government agencies in the form of grants. Incentives are recorded in the financial statements in accordance with their purposes, either as a reduction of expense or a reduction of the cost of the capital investment. The benefit of these incentives is recorded when performance is complete and all conditions as specified in the agreement are fulfilled.
California and certain other states provide incentives to accelerate the purchase of cleaner, more efficient buses in the form of point-of-sale discounts to vehicle purchasers. These incentives are included in the customer contract value, and recognized as revenue once all revenue recognition criteria are met.
Other Comprehensive Income (Loss)
The components of accumulated other comprehensive income (loss) and activity, net of related taxes, for the year ended December 31, 2022 were as follows (in thousands):
December 31, 2021 Increase/ Decrease December 31, 2022

2. Adoption of New Accounting Standards
ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. This standard simplifies the accounting for convertible instruments by removing certain separation models in ASC 470-20, Debt - Debt with Conversion and Other Options. This standard updates the guidance on certain embedded conversion features that are not required to be accounted for as derivatives under Topic 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital, such that those features are no longer required to be separated from the host contract. The convertible debt instruments will be accounted for as a single liability measured at amortized cost. This will also result in the interest expense recognized for convertible debt instruments to be typically closer to the coupon interest rate when applying the guidance in Topic 835, Interest. Further, this standard made amendments to the EPS guidance in Topic 260 for convertible instruments, the most significant impact of which is requiring the use of the if-converted method for diluted earnings per share calculation, and no longer allowing the net share settlement method. This standard also made revisions to Topic 815-40, which provides guidance on how an entity must determine whether a contract qualifies for a scope exception from derivative accounting. The amendments to Topic 815-40 change the scope of contracts that are recognized as assets or liabilities. This standard is effective for interim and annual periods beginning after December 15, 2021, with early adoption permitted after December 15, 2020. Adoption of this standard can either be on a modified retrospective or full retrospective basis. The Company adopted this standard on January 1, 2022, and it had no material impact on the consolidated financial statements.

The Merger has been accounted for as a reverse merger and a recapitalization under U.S. GAAP with Legacy Proterra being the accounting acquirer, based on evaluation of the following facts and circumstances:
•Legacy Proterra’s stockholders have a majority of the voting power of Proterra following the Merger;
•Legacy Proterra has initially designated a majority of the board of directors of Proterra;
•Legacy Proterra’s management comprise the management of Proterra;
•Legacy Proterra comprises the ongoing operations of Proterra;
•Legacy Proterra is the larger entity based on historical revenues and business operations; and
•Proterra has assumed Legacy Proterra’s name.
Under this method of accounting, ArcLight is treated as the “acquired” company for accounting and financial reporting purposes. Accordingly, for accounting purposes, this merger transaction is treated as the equivalent of Legacy Proterra issuing equity for the net assets of ArcLight, accompanied by a recapitalization. The net assets of ArcLight have been stated at historical cost, with no goodwill or other intangible assets recorded.
The Company received aggregate cash proceeds of $649.3 million at the Closing, net of $13.8 million of PIPE Financing fees, $18.5 million of other transaction costs paid at Closing, $9.7 million of ArcLight IPO deferred underwriting fees payable, $1.3 million of other ArcLight’s accrued expenses, and $0.1 million of ArcLight’s related party payable. The unbilled ArcLight expenses incurred prior to the Closing were paid from the cash proceeds received by the Company. The transaction costs including advisory, legal and other professional services directly related to the Merger were recorded in the additional paid-in capital in the balance sheet to offset against proceeds. The deferred transaction costs of approximately $2.9 million paid by the Company prior to the Closing were recorded to the additional paid-in capital and classified as financing activities in the statement of cash flow for year ended December 31, 2021.
In July 2021, the conditions for the issuance of the First Earnout Shares and the vesting of the Sponsor Earnout Stock were satisfied, resulting in an aggregate of 4,800,563 shares of common stock being issued and the 679,750 shares of Sponsor Earnout Stock fully vesting.
4. Fair Value of Financial Instruments
The Company measures certain financial assets and liabilities at fair value. Fair value is determined based on the exit price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy:
Level 1 - Quoted prices in active markets for identical assets or liabilities;
Level 2 - Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and
Level 3 - Inputs that are generally unobservable and typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability.

The Company’s short-term investments were comprised of U.S. Treasury and corporate debt securities, and classified as available-for-sale at the time of purchase because it is intended that these investments are available for current operations. Investments are reported at fair value and are subject to periodic impairment review. Unrealized gains and losses related to changes in the fair value of these securities are recognized in accumulated other comprehensive loss. The ultimate value realized on these securities is subject to market price volatility until they are sold. Realized gains or losses from short-term investments are recorded in other expense (income), net.
As of December 31, 2022, the Company has $26.6 million of long-term investments recorded in other assets in the consolidated balance sheets, comprised of minority ownership of equity investments in privately held entities.

Senior Credit Facility
In May 2019, the Company entered into a Loan, Guaranty and Security Agreement for a senior secured asset-based lending facility (the “Senior Credit Facility”) with borrowing capacity up to $75.0 million. The commitment under the Senior Credit Facility is available to the Company on a revolving basis through the earlier of May 2024 or 91 days prior to the stated maturity of any subordinated debt in aggregate amount of $7.5 million or more. The maximum availability under the Senior Credit Facility is based on certain specified percentages of eligible accounts receivable and inventory, subject to certain reserves, to be determined in accordance with the Senior Credit Facility. The commitment under the Senior Credit Facility includes a $20.0 million letter of credit sub-line as of December 31, 2022. Subject to certain conditions, the commitment may be increased by $50.0 million upon approval by the lender, and at the Company’s option, the commitment can be reduced to $25.0 million or terminated upon at least 15 days written notice.
The Senior Credit Facility is secured by a security interest in substantially all of the Company’s assets except for intellectual property and other restricted property.
PROTERRA INC
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
6. Debt (cont.)
Borrowings under the Senior Credit Facility bear interest at per annum rates equal to, at the Company’s option, either (i) the base rate plus an applicable margin for base rate loan, or (ii) the London Interbank Offered Rate (“LIBOR”) plus an applicable margin for LIBOR loan. The base rate is calculated as the greater of (a) the Lender prime rate, (b) the federal funds rate plus 0.5%, and (c) one-month LIBOR plus 1.0%. The applicable margin is calculated based on a pricing grid linked to quarterly average excess availability (as a percentage of borrowing capacity). For base rate loans, the applicable margin ranges from 0.0% to 1.5%, and for LIBOR Loans, it ranges from 1.5% to 3.0%. The Senior Credit Facility contains certain customary non-financial covenants. In addition, the Senior Credit Facility requires the Company to maintain a Fixed Charge Coverage Ratio of at least 1.00:1.00 during such times as a covenant trigger event shall exist.
There was no outstanding balance under the Senior Credit Facility as of December 31, 2022 and 2021. There was an aggregate of $17.6 million of letters of credit outstanding as of December 31, 2022.
Small Business Administration Loan
In May 2020, the Company received Small Business Administration (the “SBA”) loan proceeds of $10.0 million from Town Center Bank pursuant to the Paycheck Protection Program (the “PPP loan”) under the Coronavirus Aid, Relief and Economic Security (CARES) Act. The PPP loan was in the form of a note with an original maturity in May 2022, and was extended to May 2025 based on the SBA’s interim final rule.
In May 2022, the SBA approved the Company’s PPP loan forgiveness application, and the PPP loan of $10.0 million was forgiven in full, and the previously paid interest of approximately $0.2 million was refunded. A total of $10.2 million was recorded as gain on debt extinguishment in the Company’s consolidated statements of operations.
Convertible Notes
In August 2020, the Company entered into a Note Purchase Agreement for Secured Convertible Promissory Notes (the “Convertible Notes”). The Convertible Notes had an aggregate principal amount of $200.0 million, with cash interest of 5.0% per annum payable at each quarter end and a paid-in-kind interest of 4.5% per annum payable by increasing the principal balance at each quarter end. The Convertible Notes will mature in August 2025, and the Company may not make prepayment unless approved by the required holders of the Convertible Notes.
Each of the Convertible Notes shall rank equally without preference or priority of any kind over one another, but senior in all rights, privileges and preferences to all other shares of the Company’s capital stock and all other securities of the Company that are convertible into or exercisable for the Company’s capital stock directly or indirectly.
Prior to the maturity date or prior to the payment or conversion of the entire balance of the Convertible Notes, in the event of a liquidation or sale of the Company, the Company shall pay to the holders of Convertible Notes the greater of (i) 150% of the principal balance of the Convertible Notes or (ii) the consideration that the holders would have received had the holders elected to convert the Convertible Notes into common stock immediately prior to such liquidation event.
The Convertible Notes do not entitle the holders to any voting rights or other rights as a stockholder of the Company, unless and until the Convertible Notes are actually converted into shares of the Company’s capital stock in accordance with their terms.
The Note Purchase Agreement contains certain customary non-financial covenants. In addition, the Note Purchase Agreement requires the Company to maintain liquidity at quarter end (“Minimum Liquidity Covenant”) of not less than the greater of (i) $75.0 million and (ii) four times of cash burn for the three-month period then ended.

6. Debt (cont.)
In connection with the issuance of the Convertible Notes, the Company issued warrants to the holders of Convertible Notes to purchase 4.6 million shares of Company stock at an exercise price of $0.02 per share. The warrants are freestanding financial instruments and, prior to the Closing, were classified as a liability due to the possibility that they could become exercisable into Legacy Proterra convertible preferred stock. Upon the consummation of the Merger, the stock issuable upon exercise of the warrants is Proterra common stock, with no possibility to convert to Legacy Proterra convertible preferred stock. As a result, the carrying amount of the warrant liability was reclassified to stockholders’ equity. The warrant liability of $29.0 million was initially measured at fair value on its issuance date and recorded as a debt discount and amortized during the term of the Convertible Notes to interest expense using the effective-interest method. The warrant liability was remeasured on a recurring basis at each reporting period date, with the change in fair value reported in the statement of operations. Upon any exercise of the warrants to common stock, the carrying amount of the warrant liability is reclassified to stockholders’ equity.
Prior to the Closing, the embedded features of the Convertible Notes were composed of conversion options that had the economic characteristics of a contingent early redemption feature settled in a variable number of shares of Company stock. These conversion options were bifurcated and accounted for separately from the host debt instrument. The derivative liability of $68.5 million was initially measured at fair value on the issuance date of the Convertible Notes and recorded as a debt discount and was amortized during the term of the Convertible Notes to interest expense using the effective-interest method. The derivative liability was remeasured on a recurring basis at each reporting period date, with the change in fair value reported in the statement of operations. Upon the consummation of the Merger, the embedded conversion features associated with the Convertible Notes no longer qualify for derivative accounting since the conversion price became fixed. The carrying amount of the embedded derivative, the fair value as of the Closing Date, was reclassified to stockholders’ equity in accordance with Topic 815, Derivatives and Hedging. A summary of the changes of the derivative liability is as follows (in thousands):
Derivative liability
Fair value as of December 31, 2020 $ 70,870
Change in fair value 111,684
Reclassification of liability upon the reverse recapitalization (182,554)
Fair value as of December 31, 2021 $ -
Issuance costs of $5.1 million were also recorded as debt discount and are amortized during the term of the Convertible Notes to interest expense using the effective interest method.
On June 14, 2021, certain Convertible Note holders with an original aggregate principal amount of $46.5 million elected to convert their Convertible Notes at the Closing. An aggregate of $48.8 million principal and interest was reclassified to additional paid-in capital, and $21.0 million of remaining related debt issuance costs were expensed to interest expense.
The outstanding Convertible Notes including accrued interest will be automatically converted to common stock at $6.5712 per share pursuant to the mandatory conversion provisions, if and when the volume-weighted average price (VWAP) of the common stock exceeds $9.86 over 20 consecutive days subsequent to January 13, 2022.
The amortization expense of debt discount and issuance costs was $14.2 million, $34.7 million and $5.6 million for the years ended December 31, 2022, 2021 and 2020, respectively.

The Company was not in compliance with the the Minimum Liquidity Covenant of the Convertible Notes as of December 31, 2022. The Company received a waiver of the Liquidity (as defined therein) requirement in February 2023 which provides for retroactive effect, so that no such event of default occurred in the year ended December 31, 2022. Refer to Note 15, Subsequent Events for details.
However, the Company has not obtained a waiver of the Minimum Liquidity Covenant for any future periods, and as a result of anticipated operating cash outflows from operation, capital investment at the Powered 1 battery factory, and incremental cash payments for the Workforce Restructuring (discussed in Note 15, Subsequent Events), the Company may not meet the Minimum Liquidity Covenant as of March 31, 2023.
In addition, the audit report included elsewhere in this Annual Report on Form 10-K contains a going concern qualification. Our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern is an event of default under the Convertible Notes and the Senior Credit Facility. If we are unable to obtain a waiver for the current event of default and/or for the Liquidity requirement for the quarter ended March 31, 2023, there would be an unwaived event of default under the Convertible Notes and under the Senior Credit Facility, which would permit (i) the holders of the Convertible Notes to cause all of the outstanding indebtedness under the Convertible Notes to become immediately due and payable and (ii) the Lenders under the Senior Credit Facility to terminate all commitments to extend credit under the Senior Credit Facility and cause all of the outstanding indebtedness under the Senior Credit Facility to become immediately due and payable. If the Convertible Notes were to become immediately due and payable in the event of such a default this would have an immediate adverse effect on our ability to meet our working capital needs and our business and operating results. There is no assurance that we will be able to obtain any future waivers under the Convertible Notes or the Senior Credit Facility. We would need to take further action to raise additional funds in the capital markets or otherwise to fund our obligations under the Convertible Notes in addition to our other obligations over the period, and we would not be able to draw upon the Senior Credit Facility.
Due to the uncertainty of obtaining waivers of the Liquidity requirement for future periods and our inability to deliver audited financial statements certified by our independent registered public accounting firm without qualification (or similar notation) as to going concern, even though the Convertible Notes have a maturity date in August 2025, they are classified as a current liability on the Company’s balance sheets as of December 31, 2022.

8. Commitments and Contingencies
Purchase Commitments
As of December 31, 2022, the Company had outstanding inventory and other purchase commitments of $2.2 billion. Most of the commitments relate to the expected purchase of cylindrical cells manufactured at a yet to be built LG Energy Solution battery cell plant in the United States, pursuant to a long-term supply agreement through 2028. The terms of the agreement require the Company to make certain prepayments that vary in size and that are made as milestones are met on the construction of the US facility. As of December 31, 2022, the Company has made a $10.0 million prepayment, which was recorded as the long-term inventory prepayment on the consolidated balance sheets. The Company expects the next prepayment to be made within the next six to twelve months. The prepayments will be recouped by the Company by offsetting a predetermined amount per unit on cells purchased from LG Energy Solution.
Letters of Credit
As of December 31, 2022, the Company had letters of credit outstanding totaling $17.8 million, which will expire over various dates in 2023.
Legal Proceedings
The Company accrues contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. From time to time in the normal course of business, various claims and litigation have been asserted or commenced. Due to uncertainties inherent in litigation and other claims, the Company can give no assurance that it will prevail in any such matters, which could subject the Company to

Public Warrants and Private Placement Warrants
The public warrants and private placement warrants were issued in connection with ArcLight’s initial public offering. Public warrants were only exercisable for a whole number of shares of common stock at a price of $11.50 per share, subject to adjustment, at any time commencing on September 25, 2021. The warrants were to expire June 14, 2026 or earlier upon redemption or liquidation. The private placement warrants had terms and provisions that were identical to those of the public warrants, but were not transferable, assignable or salable until July 14, 2021, except pursuant to limited exceptions.
The public warrants and private placement warrants were classified as liabilities as they did not meet the requirements for equity classification under Topic 815, Derivatives and Hedging. Immediately prior to the Closing, the warrant liability was $84.6 million for the public warrants and $57.6 million for the private placement warrants. Such warrants were measured at fair value, subject to remeasurement at each balance sheet date.
On September 27, 2021, the Company announced that it would be redeeming all of its outstanding public warrants and private placement warrants (collectively, the “Warrants”) based on the terms in the Amended and Restated Warrant Agreement dated June 14, 2021. On October 29, 2021 (the “Redemption Date”), any Warrants that remained unexercised became void and no longer exercisable, and the holders of those Warrants were entitled to receive only the redemption price of $0.10 per Warrant. In connection with the redemption, holders of Warrants had the option to either exercise the Warrants in cash or on a “cashless” basis to receive 0.255 shares of common stock per warrant.
In October 2021, 10,599 public warrants were exercised for cash resulting in the issuance of 10,599 shares of common stock for an aggregate exercise price of $121,889, 13,436,250 public warrants and 7,550,000 private placement warrants were exercised on a cashless basis resulting in the issuance of 5,351,231 shares of common stock, and 428,145 public warrants were redeemed for cash for an aggregate redemption price of $42,815.

11. Equity Plans and Stock-based Compensation
2010 Equity Incentive Plan
In 2010, Legacy Proterra adopted the 2010 Equity Incentive Plan (the “2010 Plan”), which provided for the grant of stock options, stock appreciation rights, restricted stock, and restricted stock units. Upon Closing, the then outstanding options under the 2010 Plan were converted into options exercisable to purchase an aggregate of 22,532,619 shares of common stock. Following the Closing, such options continue to be subject to the terms of the 2010 Plan and applicable award agreements; however, no further awards can be granted under the 2010 Plan. As of December 31, 2022, options to purchase 16,642,864 shares of common stock remained outstanding under the 2010 Plan.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
11. Equity Plans and Stock-based Compensation (cont.)
2021 Equity Incentive Plan
The 2021 Plan was adopted by the ArcLight Board prior to the Closing, approved by ArcLight’s shareholders on June 11, 2021, and became effective upon the Closing Date. The Equity Incentive Plan allows the Company to grant awards of stock options, restricted stock awards, stock appreciation rights (“SARs”), restricted stock units (“RSUs”), performance awards, and stock bonus awards to officers, employees, directors and consultants.
The Company initially reserved 10,000,000 shares of common stock, plus 387,531 reserved shares not issued under the 2010 Plan on the effective date of the 2021 Plan. The number of shares reserved for issuance under the 2021 Plan increases automatically on January 1 of each of 2022 through 2031 by the number of shares equal to the lesser of 4% of the total number of outstanding shares of all classes of common stock as of the immediately preceding December 31, or a number as may be determined by the Board. In the first quarter of 2022, the shares of common stock reserved for issuance were increased by 8,878,388, pursuant to the 2021 Plan.
The exercise price of stock options granted must be at least equal to the fair market value of common stock on the date of grant. Incentive stock options granted to an individual who holds, directly or by attribution, more than ten percent of the total combined voting power of all classes of capital stock must have an exercise price of at least 110% of the fair market value of common stock on the date of grant. Subject to certain adjustments, no more than 30,000,000 shares may be issued pursuant to the exercise of incentive stock options granted under the 2021 Plan.
The maximum term of options granted is ten years from the date of grant, except that the maximum permitted term of incentive stock options granted to an individual who holds, directly or by attribution, more than ten percent of the total combined voting power of all classes of capital stock is five years from the date of grant.
Stock option and RSU awards generally vest annually over a four-year period.
2021 Employee Stock Purchase Plan
Proterra’s 2021 Employee Stock Purchase Plan (the “ESPP”), including the authorization of the initial share reserve thereunder, was adopted by the ArcLight Board prior to the Closing, approved by ArcLight’s shareholders on June 11, 2021, and became effective upon the Closing Date.
An aggregate of 1,630,000 shares of common stock were reserved and available for sale under the ESPP. The aggregate number of shares reserved for sale under the ESPP increases automatically on January 1 of each of 2022 through 2031 by a number of shares equal to the lesser of 1% of the total number of outstanding shares of common stock as of the immediately preceding December 31 or a number of shares as may be determined by the Board or the compensation committee. The aggregate number of shares issued over the term of the ESPP, subject to certain adjustments, may not exceed 16,300,000 shares. In the first quarter of 2022, the shares of common stock reserved for issuance were increased by 2,219,597, pursuant to the ESPP.
The ESPP allows eligible employees to purchase shares of common stock at a discount through payroll deductions of up to 15% of their eligible compensation, at not less than 85% of the fair market value, as defined in the ESPP, subject to any plan limitations. A participant may purchase a maximum of 2,500 shares during each 6-month offering period and $25,000 in any one calendar year. The offering periods generally start on the first trading day on or after November 15th and May 15th of each year. The first offering period started in the fourth quarter of 2021. The Company calculated the fair value of the employees’ purchase rights relating to the ESPP using the Black-Scholes model and recorded approximately $1.3 million and $0.2 million of stock-based compensation expense for the year ended December 31, 2022 and 2021, respectively. In the year ended December 31, 2022, 649,492 shares of common stock was purchased under the ESPP.

(2)Excluding 1,840,784 shares exercisable under the Equity Awards with weighted average exercise price of $19.61 per share as of December 31, 2022.
In March 2020, in conjunction with Mr. Allen’s appointment as the then President and Chief Executive Officer, the board of directors of Legacy Proterra approved a grant to Mr. Allen of stock option awards with respect to 4,685,624 shares, comprised of (1) 1,338,749 shares of a time-based award with an exercise price of $5.33 per share vesting quarterly over four years, (2) 2,677,500 shares of a time-based award consisting of four tranches with an exercise price of $11.21, $16.81, $22.41 and $28.02 per share, respectively, and vesting quarterly over four years (“Equity Awards”), and (3) 669,375 shares of milestone-based award with an exercise price of $5.33 per share vesting entirely and becoming exercisable on the first trading day following the expiration of the lockup period of the Company’s initial public offering or the consummation of a change in control of the Company or upon the consummation of a merger involving a Special Purpose Acquisition Company (“Milestone Options”).
The stock-based compensation expense for Milestone Options was recognized at the time the performance milestone became probable of achievement, which was at the time of Closing. Upon Closing, the 669,375 shares underlying the Milestone Options fully vested, and $2.1 million stock-based compensation expense was recognized in June 2021.
Aggregate intrinsic value represents the difference between the estimated fair value of the underlying common stock and the exercise price of outstanding, in-the-money stock options. The total intrinsic value of stock options exercised was $10.9 million, $12.1 million and $4.3 million for the year ended December 31, 2022, 2021 and 2020, respectively. The total estimated grant date fair value of stock options vested was $9.3 million, $13.8 million and $9.9 million for the year ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, the total unrecognized stock-based compensation expense related to outstanding stock options was $12.9 million, which is expected to be recognized over a weighted-average period of 1.8 years.

Determining Fair Value of Stock Options
The Company uses the Black-Scholes option pricing model to determine the fair value of stock options. The fair value of each stock option grant is estimated on the date of the grant. The fair value of the Legacy Proterra common stock underlying the stock options has historically been determined by the board of directors, as there was no public market for the Company’s common stock prior to Merger Closing. Therefore, the board of directors has determined the fair value of the common stock at the time of the stock option grant by considering a number of objective and subjective factors including independent third-party valuation reports, valuations of comparable companies, sales of convertible preferred stock and common stock to unrelated third parties, operating and financial performance, lack of liquidity of capital stock and general and industry-specific economic outlook, among other factors.
The fair value of stock options granted is estimated on the date of grant using the following assumptions:
Year Ended December 31,
2022 2021 2020
Expected term (in years) 6.3 6.2 6.1
Risk-free interest rate 2.0 % 1.0 % 0.5 %
Expected volatility 55.1 % 54.8 % 69.1 %
Expected dividend rate - - -
Expected Term - The Company estimates the expected term consistent with the simplified method. The Company elected to use the simplified method because of its limited history of stock option exercise activity. The simplified method calculates the expected term as the average of the vesting and contractual terms of the award.
Volatility - Since the Company has limited trading history by which to determine the volatility of its own common stock price, the expected volatility being used is primarily derived from the historical stock volatility of a representative industry peer group of comparable publicly listed companies over a period approximately equal to the expected term of the stock options.
Risk-Free Interest Rate - The risk-free interest rate is based on U.S. Treasury zero coupon issues with remaining terms similar to the expected term on the options.
Expected Dividend - The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of zero in the valuation model.
Forfeiture - All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. The Company accounts for forfeitures when they occur.

12. Net Loss Per Share
Basic net loss per share is computed by dividing the net loss by the weighted-average number of shares of common stock outstanding during the period, less the weighted-average unvested common stock subject to repurchase or forfeiture as they are not deemed to be issued for accounting purposes. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including stock options, RSU, and warrants, to the extent they are dilutive.

Adjustment for the year ended December 31, 2022 includes write-off of $62.3 million unamortized debt discount of the Convertible Notes as of December 31, 2021, offset by the $30.0 million interest expense recorded in net loss for the year ended December 31, 2022.
The outstanding Convertible Notes including accrued interest will be automatically converted to common stock at $6.5712 per share pursuant to the mandatory conversion provisions, if and when the VWAP exceeds $9.86 over 20 consecutive days subsequent to January 13, 2022.
Since the Company was in a loss position after the effect of diluted securities, no adjustment is required to the weighted-average shares used in computing the diluted net loss per share as the inclusion of the remaining potential common stock shares outstanding would have been anti-dilutive.

As of December 31, 2022 and 2021, the Company’s net deferred tax assets and liabilities were zero. The deferred tax assets consist primarily of the federal and state net operating losses. Realization of deferred tax assets is dependent upon future taxable income, if any, the amount and timing of which are uncertain. In assessing the realizability of deferred tax assets, management determined that it is more likely than not that no deferred tax assets will be realized. Therefore, the Company has provided a full valuation allowance against these deferred tax assets.

ITEM 9A. CONTROLS AND PROCEDURES
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision of and with the participation of our principal executive officer and principal financial officer, management has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) as of December 31, 2022. Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were not effective as of December 31, 2022, because of the material weaknesses in internal control over financial reporting described below in Management’s Annual Report on Internal Control Over Financial Reporting.
Our management, including our chief executive officer and chief financial officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will be able to prevent all errors and detect all fraud due to inherent limitations of internal controls. Because of such limitations, there is a risk that material misstatements will not be prevented or detected on a timely basis by internal control over financial reporting. These inherent limitations are known features of the financial reporting process. Therefore, it is possible to design into the financial reporting process safeguards to reduce, though not eliminate, the risk of errors or fraud.
Notwithstanding the material weaknesses in internal control over financial reporting identified in Management’s Annual Report on Internal Control Over Financial Reporting, our management has concluded that the consolidated financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows for each of the periods presented in conformity with U.S. generally accepted accounting principles (“US GAAP”).
Management’s Annual Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Our internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation and fair presentation of published financial statements in accordance with generally accepted accounting principles. Our internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of our management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.
Management, with the participation of the principal executive officer and principal financial officer, under the oversight of our board of directors, evaluated the effectiveness of our internal control over financial reporting as of December 31, 2022, using the framework in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that our internal control over financial reporting was not effective as of December 31, 2022, because of the material weaknesses in internal control over financial reporting described below.
We did not have a sufficient number of trained resources with assigned responsibility and accountability for the design, operation and documentation of internal control over financial reporting. As a result:
a.We did not have an effective risk assessment process that defined clear financial reporting objectives and evaluated risks at a sufficient level of detail to identify all relevant risks of material misstatement across the entity.
b.We did not have an effective information and communication process that identified and assessed the source of and controls necessary to ensure the reliability of information used in financial reporting and that communicates relevant information about roles and responsibilities for internal control over financial reporting.
c.We did not have effective monitoring activities to assess the operation of internal control over financial reporting including the continued appropriateness of control design and level of documentation maintained to support control effectiveness.
As a consequence, we did not effectively design, implement, or operate process-level control activities for substantially all of our financial reporting processes.
The material weaknesses in internal controls over financial reporting did not result in any material misstatements or omissions in our previously reported financial statements.
Our independent registered public accounting firm, KPMG LLP, who audited the consolidated financial statements included in this Annual Report on Form 10-K, issued an adverse opinion on the effectiveness of our internal control over financial reporting. KPMG LLP’s report appears on page 96.
Management’s Remediation Plan
Our management, with the oversight of the audit committee of our board of directors, is in the process of designing and implementing a remediation plan and is taking steps to remediate the material weakness. We are committed to continuing to improve our internal controls over financial reporting and make progress remediating the material weaknesses during fiscal year 2023. Management’s plan will include (1) Hiring, training, and retaining individuals with the appropriate skills and experience related to technical accounting, internal control over financial reporting, and the design and implementation of information technology solutions; (2) Enhancing risk assessment and prioritizing remediation activities that most significantly reduce the risk that a material misstatement to the consolidated financial statements would not be prevented or detected on a timely basis; (3) Implementing and monitoring our phased approach to remediation of control activities; (4) Enhancing information and communication processes through information technology solutions designed to ensure that information needed for financial reporting is accurate, complete, relevant and reliable, and communicated in a timely manner; and (5) Reporting regularly to the audit committee of the board of directors on the progress and results of our remediation plan, including the identification, status, and resolution of internal control deficiencies.
The material weaknesses will not be considered remediated until such time as management designs and implements effective controls that operate for a sufficient period of time and concludes, through testing, that these controls are effective. We will continue to monitor the effectiveness of our remediation plan and will make the changes we determine to be appropriate.
Changes in Internal Control Over Financial Reporting
Except for the identification of the material weaknesses described above, there were no changes in our internal control over financial reporting during the quarter ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Convertible Notes Waiver is a limited waiver from the Cowen Parties, acting on behalf of all of the holders of the Convertible Notes, of the Going Concern Covenant under the Note Purchase Agreement and the Convertible Notes that provides for prospective effect, such that, no default or event of default shall occur due to our or any Guarantor’s (as defined in the Note Purchase Agreement) failure to observe or perform the Going Concern Covenant with respect to the audit report contained in this Annual Report on Form 10-K until March 31, 2023. In addition, the Cowen Parties, acting on behalf of all of the holders of the Convertible Notes, agreed to waive a cross-default under the Convertible Notes with respect to the Senior Secured Credit Facility, resulting from the substantially similar covenant thereunder until March 31, 2023.
The description of the Convertible Notes Waiver does not purport to be complete and is qualified in its entirety by reference to the full text of the Convertible Notes Waiver, which is filed as Exhibits 10.43 to this Annual Report on Form 10-K.
