UNION PACIFIC CORP

Fellow Shareholders:

As Union Pacific shareholders, we own a piece of history. Over the course of 161 years, our Company is built to handle inevitable changes and challenges of business cycles while seeking ways to innovate and grow. 2023 was no different.

This year, I assumed the role of Chief Executive Officer, and Lance Fritz retired after a distinguished career. At that time, we also split the roles of Chairman and CEO and Mike McCarthy, was named Chairman of the Board of Directors. The transition was seamless, a credit to the Board, Lance, and the management team.

Since becoming CEO, I have focused the team on a multi-year strategy of “Safety + Service & Operational Excellence = Growth.” Safety must always be our first area of focus, returning everyone home safely each day. Service is all about delivering what we sold our customers, committing to what we can do and doing it with excellence. Operational Excellence is about operating efficiently and productively while maintaining a buffer to handle ups and downs of railroading.

In the second half of 2023, we achieved great momentum as the team united to deliver a shared strategy. Our fourth quarter operating metrics were the best of the year. We exited the year with a stronger service product and fluid network. Our Fourth Quarter financial results also demonstrated momentum as we achieved sequential quarterly margin improvement. For 2023, we reported earnings per diluted share of $10.45, a 7% decrease versus 2022, reflecting 1% lower volumes and an operating ratio increase of 220 basis points. To support our service product and growth, we invested $3.7 billion back into our network. Soft consumer markets, continued inflationary pressures, and new labor agreements all impacted financial results.

As we turn the page to 2024, we are looking at the opportunities ahead. The entire Union Pacific team is focused on being the industry’s best in safety, service, and operational excellence. That strategy leads to long-term growth and provides you with industry-leading returns on your investment. It’s how we win.

We understand that we hold the keys to an iconic company that helped Build America. We are propelled by that history and recognize we have an important responsibility to deliver for our stakeholders. We are grateful for this opportunity and thank you for your ownership of Union Pacific

Chief Executive Officer
