Why It Matters

• This 8-K signals that Union Pacific has publicly released its quarterly and full-year earnings and related financial information—key data investors use to assess performance (earnings, revenue, margins, guidance).
• The filing itself does not include the numeric results; investors should read the attached press release (Exhibit 99.1) or the company’s earnings materials for specific figures and management commentary.
• Timely disclosure via Form 8-K is important for market transparency and may influence trading or portfolio decisions once the detailed results are reviewed.
