XL Fleet Corp. (NYSE: XL) (“XL Fleet” or the “Company”), a leader in vehicle electrification solutions for commercial and municipal fleets, today responded to a March 3, 2021 report targeting XL Fleet, written by a short-seller with a disclosed economic incentive to negatively influence the Company’s stock price.

Upon further thorough review, XL Fleet reiterates that the report contains numerous factual inaccuracies, misleading statements, and flawed conclusions. The report should not be relied upon by existing or potential investors seeking to make an informed investment decision.

“XL Fleet has a long track record of success in the fleet electrification space, a proven business model with best-in-class technology, and a customer-centric approach,” said Dimitri Kazarinoff, CEO of XL Fleet. “We stand by the validity of our technology, the benefits it delivers to our customers, and the opportunity to further extend our leadership position in an attractive market. I am incredibly proud of what our team continues to achieve, and we remain focused on executing our strategy.”

XL Fleet system effectiveness and technology is validated by independent testing facilities following EPA standards to save fuel and maintenance costs, leading to customer re-orders that account for a majority of XL Fleet revenues since inception.

• The short-seller’s ROI calculation utilizes inaccurate information. The Total Cost of Ownership analysis included in XL Fleet’s investor presentation is accurate and based on factual inputs and assumptions, as summarized in the below table.

• In fact, XL Fleet has tested its systems with independent third parties, including ESW America, who have utilized the same EPA miles per gallon (MPG) test methodologies used by vehicle manufacturers. Testing validates that XL Fleet’s technology achieves or exceeds 25% improvement in MPG for hybrid electric vehicles (HEV) and 50% improvement for plug-in hybrid electric vehicles (PHEV).

• In fact, XL Fleet’s customers regularly achieve these and greater performance metrics in the field, with numerous published examples of fleets proactively touting these impressive results that are available on the Company’s website and social media accounts.

• In fact, XL Fleet has sold and deployed electrified powertrain systems for over 4,000 vehicles to date, with customers who have cumulatively driven more than 145 million miles with XL Fleet’s technologies.

• In fact, the short-seller report fails to recognize that, as with any motor vehicle, actual customer MPG performance heavily depends on a range of factors related to how the vehicle is used. This is especially true for commercial fleets, where payload, drive cycles and amount of idling time have significant impact on actual performance. Applications with a heavy instance of braking and acceleration events will generally deliver the best results from the system. This is a widely understood aspect of hybrid operation in commercial fleets and is transparently explained in the Company’s sales processes and referenced in marketing literature.

• In fact, independent studies show a three-fold increase in brake life with hybrid electric drive systems. XL Fleet has conservatively assumed a two-fold brake life in its published Total Cost of Ownership analysis.

• In fact, XL Fleet has steadily increased its revenue through re-orders and increasingly large order sizes from its customers, accounting for a majority of XL Fleet revenues since inception.

XL Fleet is a fleet electrification leader that is delivering innovative technology, proven customer value, growing revenues and positive gross margins, with significant opportunity for continued growth.

• XL Fleet’s current and future leadership position in the electrification space is due to its established position as a provider of hybrid electric and plug-in hybrid electric powertrain solutions. The short-seller report cites anonymous sources to erroneously suggest that this limits XL Fleet’s ability to deliver all-electric solutions in the future.

• In fact, XL Fleet has established strong relationships with leading commercial and municipal fleets throughout North America, many of whom have already expressed interest in purchasing the Company’s all-electric options once available. In addition, XL Fleet has established relationships with leading vehicle manufacturers and built a network of over 100 upfitter partner locations to establish sales, installation and service capacity with fleets. XL Fleet will leverage this portfolio of relationships once its all-electric products are in production beginning in 2022.

• In fact, XL Fleet will continue to address the lasting market opportunity for hybrid and plug-in hybrid electric vehicles, as BNEF projects that only 28% of new light commercial vehicles will be EVs in 2030.

• In fact, XL Fleet has successfully sold the majority of its electrified powertrain systems without subsidies in an industry where most sales have relied on incentives.

• In fact, XL Fleet is expanding its powertrain solution platform to include highly complementary charging infrastructure, power management and energy storage services through its XL Grid division. When combined with its real-time fleet intelligence platform, XL Link, the Company is in a uniquely strong position to scale as it diversifies its products, applications and geographies.

XL Fleet’s experienced technical and program management teams are developing a full suite of electrified powertrain systems and related energy storage systems for fleet applications.

• In fact, XL Fleet employs a highly experienced engineering team of 43 full-time engineers with an average of 17 years of relevant experience. XL Fleet has an innovation portfolio backed by deep IP and a rich patent portfolio, including 25 issued patents.

• In fact, many of XL Fleet’s team members have held senior engineering positions at leading vehicle manufacturers, Tier-1 automotive suppliers, and industry-leading automotive engineering services firms such as AVL, IAV, Ricardo plc and FEV Group – the same firms used by Ford, GM and other major automotive and commercial vehicle manufacturers. Additionally, XL Fleet’s team has decades of experience with a broad range of electrified powertrain systems including hybrid electric, plug-in hybrid electric, battery electric, and fuel cell electric systems.

• In fact, more than half of XL Fleet employees today are engineers, and the Company is further expanding the scope and scale of its in-house engineering expertise. The Company anticipates growing its full-time engineering headcount by 50% in 2021. This includes the 24 open engineering positions currently posted on the Company’s public website.

XL Fleet’s executive leadership team is execution-oriented with an unwavering commitment to the highest levels of integrity, accuracy, and performance throughout its business and reporting practices.

• The short-seller report makes numerous inaccurate or misleading assertions about XL Fleet’s long-term revenue projections and seeks to mislead investors and the market by interchangeably referring to “backlog” and “pipeline” to feed a false narrative around XL Fleet’s sales prospects.

• In fact, there is a significant and widely understood difference between backlog and pipeline. A backlog refers to the total amount of unfilled order volume backed by specific purchase orders. A pipeline refers to the aggregate of all sales leads across probability types being pursued by the sales team.

• In fact, XL Fleet’s 2017 funding round was completed in-line with comparable market valuations. The increase in XL Fleet’s valuation since this funding round reflects the significant growth achieved by XL Fleet over a more than four-year period, the value of its new public platform and its more than $400 million of cash on the balance sheet, combined with the significantly enhanced market backdrop for fleet electrification. The valuation increase is also in-line with public market comparables, which have experienced significant growth over the same time period.

• In fact, XL Fleet’s management team has a track record of successfully navigating global supply chain challenges and a highly competitive operating environment. For example, in 2019, XL Fleet, as well as major vehicle manufacturers, were impacted by a component shortage that affected battery supply. XL Fleet has since established a more robust and reliable supply chain, and now has multiple battery suppliers and proprietary battery packs in place.

• In fact, while XL Fleet did lose CARB approval status in 2019 and was unable to secure re-approval in 2020 due in part to the COVID-19 pandemic, the Company expects to receive CARB re-approval in 2021.

• In fact, XL Fleet’s most recently reported quarterly earnings included record quarterly revenue of $6.3 million and gross margins of more than 12% in the third quarter of 2020. XL Fleet looks forward to presenting its earnings for Q4 and FY 2020 on March 30, 2021.

“XL Fleet management, engineers and team members have spent over a decade building a strong business and technological leadership that enables our customers to achieve their environmental sustainability goals,” said Tod Hynes, Founder and President of XL Fleet. “We have a proven and successful track record with over 4,000 systems on the road that have driven more than 145 million customer miles. XL Fleet is well positioned to continue delivering value for customers and shareholders as we expand into new products, services, markets and geographies in the years ahead.”
