Exhibit 99.1

Protolabs Strengthens Executive Leadership Team

with Appointment of Bernardo Parlange as Chief Commercial Officer

Company also Announces Planned Retirement of

Chief Operations Officer

MINNEAPOLIS,

May 7, 2026 — Protolabs (NYSE: PRLB), the world’s leading provider of digital manufacturing services,

today announced the appointment of Bernardo Parlange as Chief Commercial Officer (CCO), effective May 18, 2026, reinforcing its

leadership team as the company continues to advance its growth strategy.

In this newly created role, Parlange will oversee Protolabs’

global commercial strategy, including sales, marketing, and customer success. He will focus on supporting the digital manufacturer’s

next phase of growth by strengthening relationships with large strategic customers and deepening engagement across the entire customer

base. Additionally, he will be responsible for helping to accelerate revenue performance across all segments, while supporting Protolabs’

broader priorities of elevating the customer experience, fostering innovation, expanding production, and promoting operational efficiency.

Parlange brings more than 20 years of experience leading B2B industrial commercial teams and scaling organizations operating in complex,

multi-market environments. Most recently, he served as Senior Vice President of Sales & Marketing at Fortrex, a Blackstone portfolio

company and leading food safety and hygiene solutions provider serving food manufacturing, food distribution, and retail environments.

Prior to Fortrex, Parlange spent 14 years at Ecolab, where he held a variety of leadership roles and a decade before that in project management

and engineering positions at ZF Group, a global technology supplier of advanced mobility products and systems.

His experience spans traditional industrial environments as well as

digital and SaaS-based platforms, and in businesses operating across multiple countries. Throughout his career, he has focused on driving

cross-functional alignment, translating customer insights into clear commercial strategies, and implementing the systems needed to deliver

consistent, profitable growth.

“Bernardo is an exceptional commercial leader who knows how to

build and scale high-performing revenue organizations,” said Suresh Krishna, President and CEO of Protolabs. “His track

record of leading global businesses will be a strong asset as we enter our next phase of growth. Bernardo will oversee our commercial

organization, with the goal of enhancing the customer experience, accelerating innovation in our core services, and expanding our production

offerings. With a diverse customer base ranging from large enterprises to small businesses and entrepreneurs, he will focus on deepening

engagement, and strengthening our role as a trusted partner across the product life cycle, with an emphasis on driving sustained, profitable

growth.”

Separately, Protolabs also announced the planned retirement of Mike

Kenison, Chief Operations Officer, effective July 1, 2026. Kenison joined Protolabs in 2006 and went on to hold several senior operational

leadership roles across the company. During his tenure, Kenison played a significant role in expanding Protolabs’ operations to

four manufacturing services, nine global factories, and more than 1 million sq. ft. of manufacturing space.

“I want to extend my sincere gratitude to Mike for his exceptional

leadership and unwavering dedication to Protolabs and to digital manufacturing over the past two decades,” said Krishna. “His

contributions have been instrumental in building and scaling our world-class global operations and positioning the company for continued

success. We are grateful for Mike’s commitment and the lasting impact he has made on Protolabs, and we wish him the very best in

his retirement.”
