SolarWindow CEO Issues Letter to Shareholders on Commercialization Strategy and Progress

Scottsdale, Arizona, August 12, 2026 -- SolarWindow Technologies, Inc. (Symbol WNDW), an energy technology company advancing transparent and flexible solar products, today released the following shareholder letter from President & CEO Amit Singh.

To Our Shareholders,

In my last letter to youI said 2026 would be a pivotal year on our path toward commercial deployment. The eight months since have brought us to the most important moment of my tenure. I have been working with our team to expand our product portfolio through the addition of market-ready technologies, and that work is now bearing fruit.

Our mission is simple: to bring first-in-class, ultra-flexible, ultra-lightweight solar products to market. From electricity-generating glass for skyscrapers to solar on surfaces no conventional panel could ever reach, we are preparing to release a family of offerings unlike anything readily available today. In the weeks and months ahead, expect to hear more. 

New products, and the revenue opportunities that follow them, do not come from luck.

They come from infrastructure: the systems we have built, the partners we have chosen, and the discipline we apply every day to turn genuine innovation into a viable commercial business and sustainable shareholder value. That is what this letter is about, because that is what will carry us through what comes next.

SolarWindow Strategic Direction

SolarWindow is advancing a technology platform with the potential to reshape how, and where, energy is generated and deployed. Our transparent, flexible, electricity-generating coatings are designed to put solar everywhere: invisible, seamlessly integrated into the world around us, across a remarkable range of applications.

Automotive. Commercial transportation. Buildings. Consumer electronics. Infrastructure. Each industry opens a different door with different Tier 1 OEM partners (original equipment manufacturers, the companies that build the vehicles, buildings, and devices around us), different integration requirements, and different timelines. This expansive market reach will deepen our industry leadership and position SolarWindow as the reference standard in transparent solar, bringing photovoltaics where they have never been seen before.

Expanding Our Technology Portfolio

Generating electricity is only the beginning. We are actively evaluating complementary technologies that extend what our coatings make possible, with the goal of growing the SolarWindow product portfolio. 

We are pursuing this expansion across the full energy value chain: how energy is generated, how it is refined and optimized, how it is stored, and how it is delivered to where it is needed. SolarWindow plans to expand with highly innovative energy products that strengthen this chain and our near-term revenue.

This disciplined approach means SolarWindow is being built not as a single-product company, but as an integrated energy platform. We expect to share specific announcements as these evaluations mature.
