Pioneer

Power Secures $6 Million PRYMUS Award from Major National Logistics Customer

Award

from One of the Nation’s Largest Package Delivery Companies Reflects Early PRYMUS Adoption Just Months After Launch

Highlights

Accelerating Demand for Scalable, Rapidly Deployable Distributed Power Solutions

FORT

LEE, N.J., May 18, 2026 /BusinessWire/ — Pioneer Power Solutions, Inc. (Nasdaq: PPSI) (“Pioneer” or the “Company”),

a leader in the design, manufacture, service and integration of distributed energy resources, power generation equipment and mobile electric

vehicle (“EV”) charging solutions, today announced a $6.0 million award for two of its PRYMUS® distributed generation

systems. The planned deployment is expected to provide prime power to two different transit hubs of one of the nation’s largest

package delivery businesses. Delivery is expected in the second half of 2026.

“This

$6.0 million PRYMUS award is an important milestone for our Energy-at-the-Edge platform and reflects early commercial traction,”

said Nathan J. Mazurek, Chairman and CEO of Pioneer. “We only officially introduced PRYMUS five months ago, so receiving this award

from a premier national customer represents to us validation of both the market opportunity and the strength of our solution. From what

we are seeing in the market, as AI-driven compute demand accelerates and utility interconnection timelines continue to extend, customers

increasingly need scalable power solutions they can deploy quickly. That is what PRYMUS was designed to deliver. Just as importantly,

the level of inbound interest, pipeline activity and quoting we are now seeing has exceeded our expectations, supporting our prospects

for 2027 and 2028.”

The

aforementioned deployments are expected to consist of eight (8) paralleled 400 kW natural gas engine sets, two (2) 480 kW battery energy

storage systems and related switchgear, electrical controls and remote monitoring systems. Pioneer intends to deliver the entire system

on trailers providing the user with rapid energization and ultimate mobility should the user choose to move the units to other sites

in the future.

PRYMUS:

Energy-at-the-Edge, Fast and Scalable

Introduced

in December 2025, PRYMUS is a distributed power package that delivers scalable, pre-engineered energy blocks of 1 MW up to 10 MW. Its

primary differentiators are speed and mobility. PRYMUS can be delivered and fully operational at a site in approximately six months,

reducing the typical two- to three-year timeline for securing utility-grade power. This fast-track deployment can provide support for

modular data centers testing new server racks with the latest AI chipsets, including next-generation NVIDIA AI chipsets, all of which

require ultra-stable power delivery and rapid response to extreme load variability.

PRYMUS

also supports industrial automation and on-premise AI compute used by sectors such as healthcare, pharma, finance, research institutions

and government, where data privacy regulations, strict compliance and IP protection may benefit from local data processing.

PRYMUS

is engineered to provide pre-configured power blocks that can be deployed in months rather than years, addressing growing constraints

in utility interconnection timelines and on-site power availability.
