3M scores just 2/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: 3M Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model estimates a company’s value by projecting its future cash flows and then discounting those back to today’s dollars. In simple terms, it asks what all of 3M’s expected future free cash flows are worth right now.

For 3M, analysts project free cash flow to rise from its most recent level of $1.25 Billion to as much as $4.90 Billion by 2029. The DCF considers both these near-term expert projections and, for years beyond 2029, Simply Wall St extrapolations. Over the next ten years, free cash flow is expected to follow a steady upward trajectory, driven by restructuring efforts and potential growth opportunities.

Based on this model, 3M’s estimated intrinsic value per share comes out to $193.68. At the latest closing price of $171.60, this suggests 3M stock is trading at an 11.4% discount to fair value, meaning the market is undervaluing the company’s future cash-generating potential.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests 3M is undervalued by 11.4%. Track this in your watchlist or portfolio, or discover more undervalued stocks.

Approach 2: 3M Price vs Earnings (PE)

The Price-to-Earnings (PE) ratio is a popular and practical way to value profitable companies like 3M because it directly links a company’s share price to its per-share earnings. It’s a quick reality check for investors: are you paying a reasonable price for each dollar of earnings? The “right” PE ratio isn’t set in stone, as it depends heavily on expectations for a company’s growth, as well as the perceived risks. Higher growth and lower risk typically justify a higher PE, while slower growth or higher risk lead investors to expect a lower multiple.

3M currently trades at a PE of 26.8x, which is a bit above its peer average of 26.2x and markedly above the Industrials sector average of 12.9x. This might raise eyebrows, but not all companies (or industries) are created equal. That is where the concept of a “Fair Ratio” comes in. Simply Wall St’s proprietary Fair Ratio for 3M is 31.7x, calculated using an in-depth formula that takes into account the company’s earnings growth outlook, profit margins, size, industry dynamics, and specific risk factors.

By weighing all these fundamentals, the Fair Ratio offers a more precise target than a simple comparison to peers or sector averages. In 3M’s case, the Fair Ratio is quite close to its current PE, suggesting the market price is generally in line with what would be expected for a business with its characteristics and prospects.

Result: ABOUT RIGHT

Upgrade Your Decision Making: Choose your 3M Narrative

Earlier we mentioned that there’s an even better way to understand valuation, so let’s introduce you to Narratives. A Narrative is your personal story and convictions about a company like 3M, anchored in numbers, but shaped by your view of its future, such as what you believe revenue, earnings, and margins could be. Simply put, Narratives connect the company’s story to a financial forecast, and then to your own estimate of fair value.

Narratives are easy to use and available to everyone on Simply Wall St’s Community page, where millions of investors share perspectives.
