Corning Inc. (NYSE:GLW)

The valuation multiples for the period between 2019 and 2023 exhibit a distinct divergence between earnings-based metrics and asset- or revenue-based metrics. While price-to-earnings and price-to-operating profit ratios showed significant volatility, the price-to-sales and price-to-book value ratios remained relatively stable or followed more gradual trajectories.

Price to Earnings (P/E) Ratio

A high degree of volatility is observed in the P/E ratio, which fluctuated from 24.78 in 2019 to a peak of 68.45 in 2020. This was followed by a sharp contraction to 32.37 in 2021 and a five-year low of 22.95 in 2022. A significant rebound occurred in 2023, with the ratio increasing to 47.27, suggesting a substantial expansion in market valuation relative to net income.

Price to Operating Profit (P/OP) Ratio

The P/OP ratio closely mirrored the movements of the P/E ratio, particularly with a sharp spike in 2020 to 55.67. Following this peak, the ratio normalized to 16.54 in 2021 and entered a period of steady growth, reaching 21.00 in 2022 and 30.86 in 2023. This indicates a gradual increase in the premium assigned to the operational earning power of the company.

Price to Sales (P/S) Ratio

The P/S ratio demonstrated the lowest volatility among the evaluated metrics. After increasing from 1.86 in 2019 to 2.51 in 2020, the ratio remained largely range-bound, fluctuating between 2.13 and 2.48 over the subsequent years, and ending the period at 2.18 in 2023.

Price to Book Value (P/BV) Ratio

An upward trend in equity valuation was evident from 2019 to 2021, with the P/BV ratio rising from 1.65 to a peak of 2.83. A slight moderation followed in the final two years, with the ratio declining to 2.51 in 2022 and 2.38 in 2023, though it remained consistently higher than the 2019 baseline.

The financial valuation metrics between 2019 and 2023 exhibit significant volatility, characterized by divergent movements between share price and earnings per share (EPS), which resulted in fluctuating price-to-earnings (P/E) multiples.

Share Price Trend

The share price followed an upward trajectory from 2019 to 2021, increasing from US$ 27.97 to a peak of US$ 41.29. This growth was followed by a consecutive two-year decline, ending the period at US$ 32.18 in 2023.

Earnings Per Share (EPS) Performance

Earnings per share demonstrated instability throughout the analyzed period. A significant contraction was observed in 2020, where EPS dropped to US$ 0.54. A recovery phase followed, with earnings peaking at US$ 1.55 in 2022, before falling sharply to US$ 0.68 by the end of 2023.

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

The P/E ratio experienced sharp fluctuations, reflecting a lack of correlation between price movements and earnings growth. The highest multiple was recorded in 2020 at 68.45, a result of the share price increasing while EPS declined. The ratio reached its lowest point in 2022 at 22.95, coinciding with the period of highest earnings. By 2023, the P/E ratio rose again to 47.27, as the contraction in earnings per share was more pronounced than the decrease in the share price.

The analysis of price multiples between 2019 and 2023 reveals significant volatility in the valuation of operating performance, characterized by a fluctuating relationship between share price and operating profit per share.

Price to Operating Profit (P/OP) Volatility

The P/OP ratio experienced an extreme spike in 2020, rising to 55.67 from 16.35 in the previous year. This was followed by a sharp correction to 16.54 in 2021. Following this normalization, the ratio trended upward for two consecutive years, reaching 30.86 by the end of 2023.

Operating Profit Performance

Operating profit per share exhibited substantial instability over the five-year period. A notable decline occurred in 2020, where profit dropped to 0.66 per share, followed by a recovery to a period high of 2.50 in 2021. From 2022 onward, a downward trend emerged, with operating profit per share falling to 1.04 by December 31, 2023.

Share Price Trends

The share price followed a growth trajectory from 2019 to 2021, peaking at 41.29. Subsequent years saw a gradual decline in market value, with the price retreating to 35.67 in 2022 and further to 32.18 in 2023.

Analysis of Valuation Divergence

The extreme P/OP expansion in 2020 was driven by a divergence where the share price increased despite a significant contraction in operating profit. Conversely, the increase in the P/OP ratio between 2022 and 2023 suggests that operating profit per share declined more rapidly than the share price, leading to an inflated multiple relative to the actual operating earnings.

The valuation multiples for Corning Inc. between 2019 and 2023 exhibit a period of initial expansion followed by a gradual contraction and stabilization. The Price to Sales (P/S) ratio reflects a significant shift in market valuation relative to revenue generation over this five-year window.

Price to Sales Ratio Trend

The P/S ratio rose sharply from 1.86 in 2019 to 2.51 in 2020, representing a substantial expansion in the multiple. This valuation level remained relatively elevated in 2021 at 2.48 before correcting to 2.13 in 2022. By the end of 2023, the ratio stabilized slightly at 2.18, indicating that the market continues to value the company's sales at a higher multiple than was observed in 2019.

Share Price Dynamics

The share price followed a trajectory of growth followed by a decline, peaking at 41.29 US$ in 2021. The increase from 27.97 US$ in 2019 to 36.88 US$ in 2020 was the primary catalyst for the spike in the P/S ratio, as the price appreciation outpaced the movement in sales. A subsequent downward trend saw the price settle at 32.18 US$ by December 31, 2023.

Sales per Share Correlation

Sales per share remained comparatively stable, with a peak of 16.76 US$ in 2022. Between 2019 and 2020, a slight decrease in sales per share (from 15.06 US$ to 14.71 US$) coincided with a rising share price, which accelerated the expansion of the P/S multiple. In 2023, a notable contraction in sales per share to 14.75 US$ occurred; because this revenue decline mirrored the drop in share price, the P/S ratio experienced a marginal increase from 2.13 to 2.18.

An analysis of the valuation multiples from 2019 to 2023 reveals a period of significant expansion followed by a moderate contraction in the price-to-book value (P/BV) ratio. The ratio rose from 1.65 in 2019 to a peak of 2.83 in 2021, before trending downward to 2.38 by the end of 2023.

Share Price Trends

The share price exhibited a strong upward trajectory between 2019 and 2021, increasing from 27.97 US$ to a high of 41.29 US$. Following this peak, a gradual decline occurred over the subsequent two years, with the price closing at 32.18 US$ in 2023.

Book Value per Share (BVPS) Dynamics

The book value per share reached its peak in 2020 at 17.25 US$. From 2021 onward, a consistent downward trend is observed, with the BVPS decreasing annually to reach 13.53 US$ by December 31, 2023. This represents a contraction in the net asset value attributable to each share over the latter half of the analyzed period.

P/BV Ratio Interpretation

The expansion of the P/BV ratio through 2021 was driven primarily by the rapid increase in share price relative to the book value. Between 2021 and 2023, the ratio declined from 2.83 to 2.38. However, this decline was partially mitigated by the simultaneous decrease in BVPS; the shrinking denominator prevented the P/BV ratio from falling as sharply as the share price did during the same window. Consequently, the market continues to value the company at a higher premium relative to its book value in 2023 than was the case in 2019.
