Solestial, Inc.

We are happy to share that York Space Systems (NYSE: YSS) has completed its acquisition of Solestial, securing a domestic source for critical space solar capability.

Solestial will operate as a wholly owned subsidiary of York, and continue to serve commercial, civil, and national security customers as we rapidly scale manufacturing of our rad-hard silicon solar cells and modules.

Solestial’s Vice President of Operations, Lisa Morris, was recently featured on In Her Orbit, a podcast celebrating women in leadership roles across the space industry.

In the conversation, Lisa shares insights from her career, lessons in leadership, and her experience building and scaling Solestial’s manufacturing operations to meet growing space solar demand.

Solestial was founded to deliver abundant energy in space, and today we’re much closer to accomplishing our mission.

We are thrilled to announce that York Space Systems (NYSE: YSS), a leading national defense and commercial prime, has entered into a definitive agreement to acquire Solestial.

Upon completion of the transaction, Solestial will operate as a wholly owned subsidiary of York and continue to serve a broad range of external commercial and government customers.

The acquisition secures a unique technology and critical space solar capability within York’s supply chain through U.S.-based manufacturing and reduces reliance on foreign-controlled materials and manufacturing. Partnering with York allows Solestial to more rapidly expand production to meet exceptional demand, deepen technical integration, and deliver resilient solar to a broader set of missions.

This strategic milestone reflects many years of hard work and dedication from the Solestial team. Thank you. Your efforts have set Solestial apart in a rapidly growing field of space solar companies. Solestial remains the only solar technology that self-heals radiation damage at operating temperatures as low as 65ºC. Our performance has been proven on-orbit and independently verified. We are delivering at volume. Our next chapter, in partnership with a leading prime, is a clear validation of both our technology and the team behind it.

Solestial: often imitated, never replicated.

Several companies offer silicon photovoltaics for space. Solestial stands apart:

☀️ We design and manufacture our own solar cells
☀️ Our cells self-heal radiation damage on orbit
☀️ Our low-temperature annealing performance is independently verified

In 2023, the French Alternative Energies and Atomic Energy Commission (CEA) validated our annealing results. Learn more: https://prn.to/4wbOUv2

Over the past year, Solestial has strengthened its leadership team to support our next phase of growth.

We welcomed a new CEO and added three key executives across Finance, Operations, and Product to help scale our manufacturing and commercialization efforts.

Clockwise from top left: CEO - Margo DeNaray; CFO - Nicolas Miltgen; VP, Operations - Lisa Morris; and VP, Product & Programs - Danny Field.

This is what relentless iteration looks like.

Some changes are easily recognizable, and yet they only tell part of our story.

A trained Solestian looks at this picture and sees countless improvements made to our cells, modules, processes and tools.

This is how we achieve rapid progress in space solar, not through a single breakthrough, but by optimizing thousands of details. Precision in every step of manufacturing enables high quality solar built for the demands of space.

The opposite is also true; a single weak point can impact the entire system. This is why every contribution at Solestial matters, and why our strong product is the result of our strong team.

Space Symposium is off to a strong start. We were thrilled to connect with our friends from the United States Space Force. Solestial’s Senior Director of Government Sales & Programs, Vince Hearn, is on site and looking forward to many more conversations this week.
