Cheers to a fresh coat of paint on homes across Saginaw! Earlier this month, HSC employees teamed up with Habitat for Humanity to volunteer in our community. Habitat for Humanity, a non-profit dedicated to building stable and strong homes, empowers families to become more self-reliant. Huge thanks to everyone who joined us in making a difference.

HSC is a place where you can flourish and feel valued. This June marks a significant step forward in building a more inclusive environment at HSC. The launch of PRISM, our new LGBTQ+ Employee Resource Group offers a safe space for colleagues and allies to connect, foster a sense of belonging and support.​

We’ve been looking forward to this day for some time!​

On the longest day of the year, solar panels with HSC poly inside are ready to capture, convert and store the energy that powers our devices. ☀️

We're excited to see the progress with the Global Electronic Council's EPEAT for Solar ecolabel.

HSC is proud to supply the high-purity, solar-grade polysilicon needed to manufacture ultra low-carbon solar panels. We're helping energy buyers lower their overall carbon footprint and create a more sustainable future.

Drives in Midland are getting more colorful! This past weekend, HSC's Women's Professional Network organized volunteers for Midland Blooms. This year, we planted marigolds along the roadside for the annual community beautification project, with over 500 volunteers in total. 

Excited to see these colors all summer long and thank you to all who participated. 👏

Our 2025 Community Calendar contest winners are here! This year's theme of "Living in the Age of Silicon" was captured by young photographers from across the Great Lakes Bay Region. Take a look at our winners and honorable mentions.
