Lam Research Corp. (NASDAQ:LRCX)

The valuation multiples exhibit a cyclical pattern characterized by an initial compression phase, a subsequent recovery and expansion, a brief period of correction, and a final stage of aggressive multiple expansion. The most significant contraction occurred between September 2021 and September 2022, followed by a sharp increase in valuation through March 2024. After a moderate decline through early 2025, all measured ratios entered a phase of rapid acceleration, reaching their historical peaks by June 2026.

Price to Earnings (P/E) and Price to Operating Profit (P/OP)

These two metrics demonstrate a high degree of correlation. Both ratios declined steadily from late 2021 to a trough in September 2022, with the P/E dropping from 18.12 to 10.51 and the P/OP falling from 15.79 to 8.94. A significant upward trend followed, peaking in March 2024 at 33.64 (P/E) and 30.42 (P/OP). Following a correction that brought the P/E down to 19.61 by March 2025, the ratio surged to a period high of 53.62 by June 2026, indicating a substantial increase in the premium investors were willing to pay relative to earnings.

Price to Sales (P/S)

The P/S ratio followed a similar trajectory, decreasing from 4.91 in September 2021 to a low of 2.83 in September 2022. An expansion phase led to a peak of 8.53 in March 2024. Despite a mid-term dip to 5.33 in March 2025, the ratio expanded aggressively in the final quarters of the period, culminating in a high of 16.77 by June 2026. This suggests a shift toward a significantly higher valuation relative to top-line revenue.

Price to Book Value (P/BV)

The P/BV ratio mirrored the trends of the other valuation metrics, falling from 13.28 in September 2021 to 6.88 in September 2022. It recovered to 15.14 by March 2024 before retreating to 9.61 in March 2025. The most dramatic increase in P/BV is observed from December 2024 onward, where the ratio climbed from 11.81 to 31.24 by June 2026, reflecting a sharp increase in market value relative to the company's accounting equity.

Overall, the data indicates a transition from a conservative valuation environment in 2022 to a highly aggressive valuation environment by 2026. The synchronization across P/E, P/OP, P/S, and P/BV suggests that the price movement was driven by broad market sentiment or anticipated growth rather than isolated changes in a single financial metric.

The valuation of the common stock exhibits a transition from a period of multiple compression to a phase of aggressive valuation expansion. While both share price and earnings per share have increased over the observed period, the rate of share price appreciation has significantly outpaced earnings growth, leading to a substantial increase in the Price to Earnings (P/E) ratio.

Share Price Volatility and Growth

A period of instability is observed between September 2021 and September 2022, with the share price declining from 54.89 to a low of 37.40. This was followed by a recovery and a sustained upward trajectory. Starting in late 2024, the price experienced exponential growth, rising from 81.05 in September 2024 to 311.35 by June 2026.

Earnings per Share (EPS) Performance

Earnings demonstrate a more stable and linear growth pattern compared to the share price. EPS rose from 3.03 in September 2021 to a peak of 3.80 in December 2022, followed by a temporary dip to 2.64 in December 2023. From March 2024 onward, a consistent upward trend is evident, with EPS reaching 5.81 by June 2026.

P/E Ratio Analysis

The P/E ratio initially contracted from 18.12 in September 2021 to a minimum of 10.51 in September 2022, suggesting a period of market devaluation. A subsequent expansion phase occurred, with the ratio climbing to 33.64 by March 2024. After a brief stabilization period between June 2024 and March 2025, the ratio surged again, culminating in a peak of 53.62 by June 2026. This trend indicates a significant increase in the premium investors are willing to pay per dollar of earnings, reflecting heightened growth expectations.

The valuation trajectory of the common stock exhibits a period of significant expansion, characterized by a substantial decoupling between the share price and operating profit per share in the later stages of the observed period.

Share Price Performance

The share price experienced an initial period of volatility and decline, reaching a low of 37.40 in September 2022. Following this trough, a recovery phase led to a peak of 92.88 in March 2024. A subsequent period of consolidation occurred between June 2024 and March 2025, after which the price entered a phase of aggressive growth, accelerating from 71.42 in March 2025 to a closing value of 311.35 in June 2026.

Operating Profit per Share (OPPS) Trends

Operating profit per share remained relatively stable through 2021 and 2022, fluctuating between 3.48 and 4.48. A contraction occurred between June 2023 and December 2023, with OPPS dipping to a period low of 2.96. From January 2024 onward, a consistent and linear upward trend is observed, with operating profit per share increasing every quarter to reach 6.55 by June 2026.

Price to Operating Profit (P/OP) Analysis

The P/OP ratio demonstrates three distinct valuation phases. First, a compression phase occurred from September 2021 to September 2022, where the ratio dropped from 15.79 to 8.94, reflecting a decline in market valuation relative to earnings. Second, a period of expansion saw the ratio climb to 30.42 by March 2024. Third, a rapid revaluation phase began in June 2025, where the P/OP ratio surged from 21.88 to 47.51 by June 2026.

Valuation Correlation

While both share price and operating profit grew in the final two years of the period, the rate of share price appreciation far exceeded the growth in operating profitability. Between March 2025 and June 2026, the share price increased by approximately 336%, while the operating profit per share increased by 58%. This disparity drove the P/OP ratio to its historical peak, suggesting an increase in market expectations or a significant premium attributed to future growth prospects.

The price-to-sales (P/S) ratio exhibits significant volatility over the observed period, characterized by an initial contraction followed by a period of aggressive valuation expansion. The overall trajectory indicates a shift in market sentiment, where the share price eventually began to grow at a rate far exceeding the growth in sales per share.

Valuation Contraction (September 2021 – September 2022)

A downward trend is observed during this period, with the P/S ratio declining from 4.91 to a low of 2.83. This compression occurred despite a gradual increase in sales per share, which rose from 11.19 to 13.20, suggesting that the decline in valuation was driven primarily by a reduction in share price.

Recovery and Initial Expansion (December 2022 – March 2024)

The valuation entered a recovery phase, with the P/S ratio climbing from 3.39 in December 2022 to a peak of 8.53 by March 2024. During this interval, the share price rose sharply from 47.86 to 92.88, while sales per share remained relatively stagnant or slightly declined, resulting in a higher valuation multiple.

Correction and Stabilization (June 2024 – March 2025)

A period of valuation correction is evident as the P/S ratio retreated from 6.95 in June 2024 to 5.33 by March 2025. This decline corresponds with a dip in share price to 71.42, occurring even as sales per share began to trend upward again toward 13.40.

Accelerated Valuation Surge (June 2025 – June 2026)

The final period is marked by a rapid and substantial increase in the P/S ratio, ascending from 7.00 in June 2025 to 16.77 by June 2026. This surge is attributed to an exponential increase in share price, which climbed from 102.00 to 311.35, significantly outpacing the growth in sales per share, which reached 18.57.

In summary, the data reveals a transition from a conservative valuation environment to a highly premium one. The P/S ratio's increase from 2.83 to 16.77 underscores a dramatic increase in the market's willingness to pay for each dollar of sales, indicating heightened growth expectations or a shift in the perceived risk profile of the equity.

The valuation of the common stock relative to its book value exhibits three distinct phases: an initial contraction, a period of moderate volatility, and a final phase of aggressive expansion. While the book value per share maintained a consistent upward trajectory over the analyzed period, the price-to-book value (P/BV) ratio fluctuated significantly, driven primarily by volatility in the market share price.

Book Value Progression

A steady and incremental increase in book value per share is observed, rising from 4.13 US$ in September 2021 to 9.97 US$ by June 2026. This consistent growth indicates a persistent accumulation of net assets on a per-share basis throughout the observed timeframe.

Initial Valuation Compression

Between September 2021 and September 2022, the P/BV ratio experienced a notable decline, falling from 13.28 to a period low of 6.88. This compression occurred despite a rise in book value, reflecting a significant decrease in the market price of the shares during this interval.

Mid-Term Volatility and Recovery

From September 2022 through March 2025, the P/BV ratio entered a volatile recovery phase. The ratio peaked at 15.14 in March 2024 before correcting to 9.61 by March 2025. During this window, the valuation multiple shifted in response to share price movements that outpaced the linear growth of the underlying book value.

Exponential Valuation Expansion

A sharp upward trend in the P/BV ratio began after March 2025, accelerating rapidly to reach 31.24 by June 2026. This surge is primarily attributed to a dramatic increase in share price, which rose from 71.42 US$ in March 2025 to 311.35 US$ in June 2026, leading to a valuation multiple that is significantly higher than the historical average of the preceding years.

In summary, the divergence between the steady growth of the book value and the volatile movement of the share price resulted in a final P/BV ratio that is more than double the initial valuation. This suggests a substantial increase in the market's premium assigned to the company's net assets toward the end of the period.
