Union Pacific Corp. (NYSE:UNP)

Analysis of the common stock valuation ratios reveals a period of volatility characterized by a general contraction in valuation multiples through late 2022, followed by a recovery and subsequent expansion leading into mid-2026. While earnings-based and sales-based ratios exhibit correlated cyclical patterns, the book value ratio demonstrates a distinct long-term contraction.

Earnings and Operating Profit Multiples

The Price to Earnings (P/E) and Price to Operating Profit (P/OP) ratios demonstrate a high degree of correlation throughout the observed period. Both metrics experienced a contraction in 2022, with P/E reaching a low of 16.21 and P/OP reaching 11.53 by September 30, 2022. This decline was followed by a steady recovery, peaking in December 2023 at 23.85 for P/E and 16.75 for P/OP. Following a phase of relative stability during 2024 and 2025, both ratios trended upward in the final quarters, with P/E reaching 24.67 and P/OP reaching 17.78 by June 30, 2026.

Revenue-Based Valuation

The Price to Sales (P/S) ratio followed a trajectory similar to the earnings multiples, though the trough occurred later. The ratio declined from 6.77 in March 2022 to a minimum of 4.93 in March 2023. A recovery phase ensued, leading to a peak of 6.31 in December 2023. The ratio remained largely range-bound between 5.31 and 6.17 throughout much of 2024 and 2025 before accelerating to a period high of 7.12 by June 30, 2026.

Asset-Based Valuation

In contrast to the other metrics, the Price to Book Value (P/BV) ratio exhibited a persistent downward trend for the majority of the period. Starting at a high of 12.90 in March 2022, the ratio declined steadily, reaching a low of 7.54 by September 30, 2025. This suggests a significant compression in the market premium assigned to the company's book value. A modest recovery is observed in the final three quarters, with the ratio ascending to 8.75 by June 30, 2026.

The valuation metrics exhibit a period of significant volatility followed by a phase of steady earnings growth and a subsequent expansion in the market multiple.

Share Price Trends

A notable decline occurred throughout much of 2022, with the price reaching a period low of 186.45 in September. Following this trough, the price stabilized and entered a recovery phase. A significant and sustained upward trajectory is observed beginning in early 2026, with the price ascending from 215.45 in March 2025 to a peak of 304.33 by June 30, 2026.

Earnings per Share (EPS) Performance

Earnings remained relatively range-bound between 2022 and 2023, experiencing a slight dip to 10.44 in September 2023. From March 2024 onward, a consistent and linear growth trend is evident, with EPS rising from 10.47 to 12.34 by June 2026. This indicates a steady improvement in fundamental profitability over the latter half of the analyzed period.

Price-to-Earnings (P/E) Ratio Dynamics

The P/E ratio underwent several distinct phases. Initial valuation compression is observed in 2022, where the ratio dropped from 22.53 to 16.21. This was followed by a recovery and expansion phase, peaking at 23.85 in December 2023. A secondary contraction occurred between March 2024 and September 2025, during which the P/E ratio declined to 18.51 even as earnings grew, suggesting that price appreciation lagged behind earnings growth. The period concludes with a sharp expansion in the multiple, reaching 24.67 by June 2026, driven by the rapid increase in share price relative to the growth in EPS.

The valuation of Union Pacific Corp. between March 2022 and June 2026 is characterized by significant share price volatility contrasted against a relatively stable and incrementally growing operating profit per share. This divergence resulted in a Price to Operating Profit (P/OP) ratio that fluctuated primarily in response to market sentiment and share price movements rather than drastic changes in operational profitability.

Share Price Volatility and Growth

The share price exhibited a cyclical pattern, starting at 244.40 USD in March 2022 before declining to a period low of 186.45 USD by September 2022. Following this trough, the price stabilized and fluctuated between approximately 200 USD and 250 USD through 2023 and 2024. A sustained bullish trend emerged in early 2025, with the price ascending from 215.45 USD in March 2025 to a peak of 304.33 USD by June 2026.

Operating Profit Stability

Operating profit per share remained remarkably consistent over the observed period, maintaining a tight range between 14.89 USD and 17.12 USD. A minor contraction occurred between June 2023 and December 2023, where profit dipped from 15.66 USD to 14.89 USD. However, from March 2024 onward, a steady upward trajectory was established, culminating in the period high of 17.12 USD in June 2026.

P/OP Ratio Analysis

The P/OP ratio mirrored the volatility of the share price due to the stability of the denominator. The ratio reached its lowest point of 11.53 in September 2022, coinciding with the share price bottom. A valuation peak of 16.75 occurred in December 2023. Between March 2024 and September 2025, the ratio compressed and stabilized between 13.09 and 16.22. The final phase of the period saw a significant valuation expansion, with the P/OP ratio rising to 17.78 by June 2026, driven by a share price increase that outpaced the growth in operating profit.

The overall trend indicates that while operational efficiency and profitability grew steadily, the market valuation experienced broader swings. The terminal increase in the P/OP ratio suggests an expansion in the multiple investors were willing to pay for each dollar of operating profit toward the end of the series.

An analysis of the valuation metrics from March 2022 through June 2026 reveals a period of significant volatility in market valuation relative to revenue, followed by a strong expansion in the Price-to-Sales (P/S) ratio. While top-line revenue per share maintained a steady growth trajectory, the market valuation fluctuated more aggressively, indicating shifts in investor sentiment and market pricing.

Price-to-Sales (P/S) Ratio Trends

The P/S ratio experienced an initial contraction, falling from 6.77 in March 2022 to a low of 4.69 by September 2022. This was followed by a recovery phase and a period of relative stability between 5.31 and 6.17 through much of 2024 and 2025. A notable expansion occurred in the final three quarters of the observed period, with the ratio climbing to 7.12 by June 2026, representing the highest valuation multiple in the series.

Sales per Share Performance

Sales per share demonstrated consistent growth, increasing from 36.09 in March 2022 to 42.77 in June 2026. This steady upward movement suggests a reliable increase in revenue generation per share, providing a stable denominator against which the market price fluctuated.

Share Price Correlation and Valuation Impact

The share price acted as the primary catalyst for changes in the P/S ratio. The decline in the P/S ratio during late 2022 was driven by a share price drop to 186.45. Conversely, the expansion of the P/S ratio toward the end of the period was driven by a significant increase in share price, which reached 304.33 by June 2026, far outpacing the growth rate of sales per share and resulting in a higher valuation multiple.

An analysis of the valuation metrics from March 2022 through June 2026 reveals a significant compression in the Price to Book Value (P/BV) ratio, occurring simultaneously with a steady increase in the underlying book value per share.

Book Value per Share (BVPS) Trends

A consistent upward trajectory is observed in the book value per share, which rose from 18.94 US$ in March 2022 to 34.80 US$ by June 2026. This represents a substantial growth in the net asset value attributed to each share. While a minor contraction occurred in March 2025, the overall trend remained positive and stable throughout the analyzed period.

Share Price Volatility

The share price exhibited considerable volatility, particularly between 2022 and 2023. After an initial decline from 244.40 US$ in March 2022 to a low of 186.45 US$ in September 2022, the price entered a recovery phase. A period of sustained growth is evident from December 2025 through June 2026, with the price reaching a peak of 304.33 US$.

P/BV Ratio Compression

The P/BV ratio experienced a marked decline over the observation window. The ratio started at a high of 12.90 in March 2022 and trended downward, reaching a low of 7.54 in September 2025. This compression indicates that the market valuation of the company relative to its book value decreased, even as the absolute share price increased in later periods.

Valuation Correlation

The divergence between the rising share price in 2026 and the relatively low P/BV ratios suggests that the growth in book value per share outpaced the growth in the market price relative to early 2022 levels. Consequently, the stock became more "reasonably" priced relative to its assets by June 2026, with a P/BV of 8.75, compared to the premium valuation of 12.90 seen at the start of the period.
