Workhorse Group Reports Third Quarter 2023 Results CINCINNATI, November 14, 2023 -- Workhorse Group Inc. (Nasdaq: WKHS) (“Workhorse” or “the Company”), an American technology company with a vision to pioneer the transition to zero emission commercial vehicles, today reported financial results for the third quarter ended September 30, 2023. Management Commentary “We continued to deliver on our key priorities during the third quarter, making important progress across our commercial EV, drone and last mile delivery product roadmaps,” said Workhorse CEO Rick Dauch. “In Q3, we completed both durability and systems testing, which enabled us to launch production of the W56 stripped chassis and step van models on time. We also increased production and successfully completed customer demonstrations of the W750 step van. We added two new certified dealers to our commercial vehicle network. At our Aero business, we continue to work closely with UPS Flight Forward to put our aircraft on their FAA Part 135 certificate. We sold UPS additional drones for FAA certification and field testing. Across both our Commercial Vehicle and Aerospace businesses, our teams are delivering with dedication and hard work to create high quality, reliable, industry-leading products for our customers.” Mr. Dauch continued, “While we made tremendous progress in the areas within our control, our ability to deliver W4 CCs and W750s during the quarter was severely impacted by the lack of HVIP voucher availability in California. As of today, I am pleased to report that we have successfully resolved this issue and are moving swiftly ahead. On November 8, we received approval to participate in a first-of-its-kind program that the California Air Resources Board (“CARB”) has now put in place for HVIP certification in California, and Workhorse is the first company to receive this approval. We sincerely appreciate the problem-solving efforts of CARB. While this delay impacted our financial results for the third quarter and our outlook for the remainder of this year, we are now in a position to execute free of constraints. We feel strongly that we have the right products targeting the right market segments as we help drive the transition to EV powered commercial work trucks in California and other states adopting the CARB Clean Fleet mandates in 2024 and beyond. With the strong technical, operating and commercial foundations we now have in place, we are poised to win in the market and deliver long-term shareholder value.” Executing Strategic Commercial Vehicle Product Roadmap Workhorse continues to execute its strategic product roadmap for its electric vehicle delivery offerings. • W56: During the third quarter, Workhorse began production of both the stripped chassis and step van models, after successfully completing all FMVSS, durability and validation testing. Workhorse has initial production demonstration units in the field in California with multiple customers, with initial feedback being extremely positive on performance in real-world last-mile routes. The Company anticipates final HVIP certification of the W56 to be completed in Q4 2023. • W4 CC/W750: The Company has reached production of four W750s per week, shipped demonstration vehicles to potential customers and completed demonstration tests with city government agencies in California and two 30-day delivery routes for a major office supply company on the East Coast. Given current inventory levels, the Company temporarily paused further production of the W4 CC pending resolution of the HVIP voucher matter in California.

• Continued Build Out of Commercial Footprint: Workhorse successfully added two new certified dealers to the network. • Received Internal Revenue Service Approval as a Qualified Manufacturer for the Commercial Clean Vehicle Credit. This approval provides Workhorse customers eligibility to receive up to a $40,000 federal tax credit per vehicle for deliveries of all Workhorse vehicles in 2023 and beyond. • Enhanced the Company’s Facilities and Team: The Company is adding plant and product staff at its facilities at a pace to match production demand. At the Union City, IN plant, installation of the in-house paint system was completed and placed into service, representing the last major capital investment for the facility. • Stables by Workhorse: Workhorse’s Stables operations continues to successfully deliver last mile packages for FedEx Ground and incrementally grow route assignments. Workhorse has electrified over half of the Lebanon, OH fleet and is continuing to review options to partner with operators in other incentive-based states. Workhorse now has seven Class 4 EV units in the delivery fleet and plans to add W56 vehicles to the fleet in Q4 2023. Achieved Milestones in Aerospace Business & Exploring Strategic Alternatives Workhorse achieved notable milestones during the third quarter including: • Began drone assembly in the Mason, OH facility. The Company sold and delivered 3 additional drone aircraft. • Received two additional grants, expanding work for USDA. The two grants total approximately $1.1 million, adding watershed scanning for the National Conservation Resources Service and more farms to the agricultural work the Company has done for the USDA over the last two years. • Entered the Federal Aviation Administration (“FAA”) 44807 Exemption process. Workhorse has begun the process to place the WA4-100, known as HorseFly, on UPS Flight Forward’s (UPSFF) FAA Part 135 “drone airline” certificate and plans to have the HorseFly approved for FAA Part 135 operations by the end of 2023. The Company is evaluating a broad range of strategic alternatives for its Aero business which may include a sale of the business, strategic partnership, another transaction or the continued execution of the Company’s strategic plan for Aero within Workhorse. The Company has not set a timetable for completion of the process and does not intend to comment further until the process is complete. Mr. Dauch added, “Our highly experienced Aero team has significantly advanced our drone business and is commercializing market-leading, safe and reliable technology that has drawn customer interest as well as continuing to progress in the FAA approval process. With this foundation in place, we believe evaluating options for the business is a prudent step forward to ensure we are unlocking the most value for Workhorse while best positioning the Aero business to capture the market opportunities ahead.”

Third Quarter Financial Results Sales, net of returns and allowances, for the third quarter of 2023 were recorded at $3.0 million compared to $1.5 million in the same period last year. The increase in sales was primarily driven by the reversal of a $2.4 million sales allowance in the current period related to the sale of W4 CC vehicles in the second quarter of 2023. Cost of sales decreased to $6.6 million for the third quarter of 2023 compared to $9.5 million in the same period last year. The decrease was primarily due to a $2.9 million reduction in inventory reserves and adjustments in the same period a year ago as a result of the disposition of C-Series inventory. Lower sales volume in the current period reduced costs by $1.0 million, which was offset by a $1.2 million increase in employee compensation and related expenses as the Company continued to expand its Union City, IN workforce to support future vehicle production. Selling, general and administrative (“SG&A”) expenses for the third quarter of 2023 decreased to $11.8 million compared to $34.8 million in the same period last year. The decrease was primarily driven by a $23.9 million reduction in expenses associated with the settlement of securities and shareholder derivative litigation incurred in the same period last year. Employee compensation and related expenses, including non-cash stock-based compensation expense, decreased by $0.4 million compared to the prior period, which was offset by a $0.8 million increase in professional services and other expenses. Research and development (“R&D”) expenses for the third quarter of 2023 decreased to $5.8 million compared to $6.1 million in the same period last year. The decrease was driven by a $0.9 million reduction in consulting expenses partially offset by a $0.5 million increase in employee compensation and related expenses. Net interest income for the third quarter of 2023 was $0.4 million compared to $0.0 in the same period last year. Net interest income in the current period was driven by interest earned on cash in the Company’s money market investment account. Other loss for the third quarter of 2023 was $10.0 million compared to $13.4 million in other income for the same period last year. Other loss in the current period represents impairment of the Company’s investment in Tropos resulting from the economic conditions and uncertainties that have significantly affected Tropos’ performance and financial position. Other income in the prior period was recognized in connection with the sale of C-Series inventory that was previously reserved. Net loss for the third quarter of 2023 was $30.6 million compared to a net loss of $35.4 million in the same period last year. As of September 30, 2023, the Company had total working capital of $71.9 million, including $38.9 million in cash. 2023 Full Year Revenue Guidance Update Workhorse now expects 2023 full year revenues to be in the range of $10 million to $15 million. “Our financial results for the third quarter and our outlook for the year were significantly impacted by the HVIP voucher delays,” said Workhorse CFO Bob Ginnan. “The positive resolution of the HVIP voucher is

great news and provides meaningful momentum exiting 2023; however, in light of this market disruption and the delayed timing for access of our products to the California market, we are significantly reducing our revenue outlook for the remainder of 2023.” “Importantly, we are taking major steps to strengthen our financial position and ensure we have the runway to execute our strategic and future product plans. We are in advanced discussions with third parties to obtain additional financing to support our growth plans. We are also evaluating other options to strengthen our liquidity position.” Conference Call Workhorse management will hold a conference call today November 14, 2023 at 8:00 a.m. Eastern time (5:00 a.m. Pacific time) to discuss these results and answer related questions.
