HF Sinclair

This Memorial Day, we honor those who lost their lives while serving in the U.S. military. Their sacrifice is carried forward in the lives they touched and the legacy they leave behind. We invite you to take a moment to read the reflections shared by members of HF Sinclair’s Veterans in Energy Employee Resource Group and to pause in remembrance of this day.

Safety excellence on full display 👏

During the May 7 American Fuel & Petrochemical Manufacturers National Occupational & Process Safety Conference, HF Sinclair teams were recognized as being among the best in the industry:

Puget Sound – Elite Gold (top 5%)
El Dorado, Cheyenne, Tulsa – Elite Silver (top 10%)
Casper – Safety Achievement

These awards reflect the dedication, leadership and care our teams bring to safety every day. Well-earned recognition for outstanding teams across HF Sinclair.

Asphalt plays a role in everyday life – from the roads we drive to the roofs over our heads. But none of it happens without the people behind it.

Today, we’re celebrating our asphalt team and the pride they bring to their work every day. Thank you to those who make it all possible!

News Release: HF Sinclair Reports 2026 First Quarter Results and Announces Regular Cash Dividend

April is National Safe Digging Month in the United States, a timely reminder that safe excavation practices extend well beyond the energy industry.

Whether installing a fence, planting a tree, or beginning a construction project, one critical step should always come first: checking for underground utilities.

While National Safe Digging Month is a U.S. observance, safe digging practices are important everywhere. Wherever you are, we encourage you to connect with your local utility providers before breaking ground.

In the U.S., dial 811 or submit a request online. In Canada, visit Click Before You Dig. Both are free services that connect residents with local utility providers to identify and mark underground infrastructure before work begins.

At HF Sinclair, protecting people and critical infrastructure is central to everything we do. This month and every month, we encourage everyone to call before you dig!

At HF Sinclair, our community investment efforts, which encompass our commitment to safety and reliability for our neighbors, our environment and our people, guide how we show up both at work and the communities where we operate.

Our Puget Sound refinery recently presented a $25,000 check to the Anacortes Fire Department (AFD) in support of its expanding safety initiatives. The funds will go toward safety technology for the department's new fire-rescue boat, strengthening response capabilities in the challenging conditions of our shared waterways.

Anacortes is home to many of our team members and their families, making this partnership especially meaningful.

Thank you, AFD, for your dedication to keeping this community safe.

When Wyoming’s Carbon County Sheriff’s Deputies and Search & Rescue volunteers faced a high-risk mission in the Platte River Wilderness, communication was nearly impossible.

Thanks to HF Sinclair’s commitment to safety and community, that’s changing. Our grants funded:

🛜 Starlink Mini systems for reliable connectivity
🚨Two snowmobile trailers for rescue operations
🔋 A large-scale Starlink unit with solar panels and a generator

Reliable communication across almost 8,000 square miles of rugged terrain helps save lives and we’re proud to help make it possible.
