Corning scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Corning Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow (DCF) model estimates a company’s true value by projecting its future cash flows and discounting them back to today’s dollars. This gives investors a sense of what the business is really worth, based on its ability to generate cash.

For Corning, the DCF uses the 2 Stage Free Cash Flow to Equity method. Right now, Corning’s trailing twelve-month Free Cash Flow sits at $938 million. Analyst estimates project that number to exceed the billion-dollar mark in the coming years, reaching $3.39 billion by 2029. While analysts typically forecast only a few years ahead, these longer-term figures are calculated by extending those trends forward.

Based on this analysis, the fair value of Corning’s stock is estimated at $65.81 according to the DCF approach. With the current share price trading about 27.0% above this level, the DCF suggests that the stock is significantly overvalued at this time.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Corning may be overvalued by 27.0%. Discover 923 undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Corning Price vs Earnings

The Price-to-Earnings (PE) ratio is widely used to value profitable companies like Corning because it relates a company’s share price to its earnings. This provides a snapshot of how much investors are willing to pay for each dollar of profit.

Growth expectations and risk both play a critical role in what a fair PE ratio should be. If a company is expected to grow faster or has lower risks compared to its peers, the market will generally award it a higher PE multiple. In contrast, slower growth or higher risks usually result in a lower PE ratio.

Corning is currently trading at 52.5x earnings, which is significantly higher than the Electronic industry’s average of 24.7x and also above the peer group average of 80.6x. At first glance, this could make the stock appear expensive, especially compared to most peers and industry norms.

The “Fair Ratio,” calculated by Simply Wall St, provides a more detailed calculation. It considers Corning’s unique profile, including expected earnings growth, risk, profit margin, industry, and market capitalization to suggest what a reasonable multiple should be. For Corning, the Fair Ratio is 38.3x. This tailored benchmark is more insightful than a plain industry or peer comparison because it takes into account the nuances of Corning’s actual prospects and challenges.

Since Corning’s current PE ratio (52.5x) sits well above its Fair Ratio (38.3x), the analysis suggests the stock may be overvalued using this approach.

Result: OVERVALUED
