3M

3M reported second-quarter organic sales growth of 5.4% year over year. Management raised its full-year guidance for organic sales and earnings per share growth.

Why it matters: Under Bill Brown's leadership, 3M has shown all the signs of a return to volume-driven organic growth. Its industrial, safety, and electronics divisions have seen sales volume growth inflections. 3M's New Product Vitality Index measures the percentage of sales from products introduced within the last five years. NPVI troughed in 2024 at 11% and now sits in the midteens, still well below the firm's average of around 30% a decade ago. After being forced to discontinue certain data center product lines, such as Novec immersion cooling, 3M has reentered the end market by developing optical connectors in partnership with Microsoft.

The bottom line: We maintain our $120 fair value estimate for narrow-moat 3M. The shares trade as overvalued in 2-star territory. 3M's economic moat has visibly eroded at the margins over the past decade from factors such as share pressure in respirators from Honeywell, private-label competition in the consumer segment, and abrasives patent challenges from Saint-Gobain. We reiterate our model's assumptions for revenue growth slightly above GDP, a return to mid-20s operating margin into the 2030s, and returns on invested capital in excess of 3M's 8% cost of capital for 10 years.

Our $120 fair value estimate is roughly 13 times 3M's 2026 adjusted earnings per share, which is a significant discount relative to the US multi-industrial category and 3M’s peers. We view this as reasonable, given the firm’s legal uncertainties and uninspiring growth profile.

We think 3M will increase its top line organically by around 3.5% over our long-term forecast, in line with GDP as most of its markets are mature. In addition to share buybacks, we expect 3M to realize margin improvements from operating leverage and efficiency gains, driving mid-single-digit EPS growth over the long term.

In the coming decade, we think 3M can maintain excess returns on capital over its estimated cost of capital of around 8.0%. However, our confidence has declined substantially in 3M’s ability to generate excess returns over a multidecade horizon, as issues regarding PFAS could take decades to resolve. We do remain confident in 3M's liquidity position to fund its dividend and no longer believe it will have to take on more debt during our explicit forecast. In addition to the $10 billion-plus liability booked related to PFAS and the recent Combat Arms earplug settlement, we think 3M will be on the hook for nearly $10 billion more in PFAS-related legal liabilities in a base-case scenario. 3M snapped its 64-year streak of dividend growth to fund its legal settlements, and ensuing litigation could threaten future dividend payments.

We like 3M's higher-conviction bets, such as in automotive electrification where it derives significant advantages from spec-in projects with auto OEM customers. These bets have started paying off and should become more apparent as 3M continues to prune the softer portions of its portfolio in which it has a limited reinvestment runway. We also think 3M's core businesses will continue pulling their weight, including personal protection equipment, industrial adhesives, automotive, and home improvement products. With 3M's current lineup, we expect the firm will increasingly direct its R&D and capital expenditures toward these divisions, which we believe can grow faster than GDP. Generally, the PPE market is driven by rising employee health and safety regulations and heightened manufacturing and construction activity in developing economies. The firm is well positioned in this segment, in our view, given its brand strength and material science competency.

3M has a narrow moat primarily driven by intangible assets and a cost advantage. Our confidence in 3M’s ability to generate returns on invested capital above its cost of capital over a multidecade period has waned substantially in recent years. We believe 3M’s economic moat is weakening, as evidenced by declining gross margins, returns on capital, and organic volume growth. It also has substantial legal uncertainties regarding PFAS that could, in an unlikely but possible scenario, bankrupt the firm. On a stand-alone basis, each of 3M's segments merits a narrow moat.

3M's "secret sauce" is its centralized research and development apparatus. It has helped 3M create a stable of brands and proprietary technology. These intangibles give 3M pricing power; excluding electronics, 3M has historically raised its prices by 30-50 basis points above inflation. 3M also commands premium pricing over competing products, typically between 10% and 30%.

We believe 3M uses its manufacturing scale to achieve the lowest unit cost in most of the categories in which it competes. It invests heavily in R&D, averaging around 6% of sales. Although this figure has declined in recent decades, it is still markedly higher than the peer average of 3.5%. 3M has developed over 50 technology platforms that it leverages across its 60,000-product base. By using the same manufacturing assets for many product lines, 3M reduces the marginal cost to make an additional unit, giving it economies of scope. Examples of shared technologies include abrasives used in sanding discs, kitchen sponges, and headlight cleaners, and adhesives used in electrical tapes, Post-it notes, and cardboard bonding.

We believe 3M’s safety and industrial segment merits a narrow moat. Historically, this segment boasts midteens returns on invested capital. Within the segment, 3M’s abrasives division has carved a narrow moat through brand strength (from brands such as Scotch-Brite and Cubitron) and economies of scope. Abrasives innovations that the firm pioneered include precision-shaped grains made possible by 3M’s microreplication technology.

The segment’s industrial adhesives and tapes and automotive aftermarket divisions follow the same formula of narrow moats derived from intangible assets and cost advantage. These divisions each have brands that leverage the same proprietary technologies 3M has developed in-house, allowing 3M to generate economies of scope.

The narrow-moat closure and masking systems division sells packaging consumables and equipment. Such equipment is installed into customer operations, providing switching costs.

The firm’s electrical markets division has no moat as it mostly sells commodity-like products such as heat-shrink tubing, wiring, and cable components. Electrical connectors that operate in harsh environments are more differentiated, but they represent a small portion of the division.

We believe the segment’s only wide-moat division is personal safety, in which 3M holds strong market share with a portfolio of brands such as Peltor and Speedglas. 3M dominates disposable respirators, fire safety, and fall protection equipment. A high cost of failure and regulatory hurdles give value to 3M’s time-tested brands.

We think the roofing granules division has a narrow moat from intangible assets and a cost advantage. 3M has participated in this market for over a century, and we believe its classic granules are the industry standard. 3M has developed numerous specialty granules, including smog-reducing and solar-reflective granules.

Within 3M’s second narrow-moat business segment, transportation and electronics, we assign its advanced materials division a narrow moat derived from intangible assets and a cost advantage. 3M's high levels of R&D spending have resulted in differentiated composite resins, polymer additives, and magnetic sheets, among others.

We think the segment’s automotive and aerospace division has a narrow moat originating from intangible assets and a cost advantage. The majority of this division’s revenue, we believe, comes from automotive products, which generally possess weaker competitive advantages than plane parts.

3M’s narrow-moat commercial solutions division, which includes products like antislip mats, fire barriers, and chemical sorbent pads, uses the same technologies as other divisions, such as films, tapes, and adhesives, giving rise to economies of scope.

3M’s transportation safety division manufactures reflective signage for roads and benefits from intangible assets and a cost advantage to form a narrow moat. Road infrastructure is highly regulated, and 3M’s products play a critical role in ensuring the safety of motorists.

We believe the consumer segment has a narrow moat. 3M’s consumer businesses generate the company’s highest returns on invested capital, averaging in the mid- to high 20s, in line with high-performing peers such as Clorox and Kimberly-Clark. Within the segment, we think the home, health, and auto care division has a wide moat as it contains some of the firm’s strongest brands, such as Ace bandages and Scotch-Brite sponges, along with economies of scope and scale.

We assign 3M’s construction and home improvement division a narrow moat. Its brands include Scotch masking tape, Filtrete air filters, and Command hanging solutions. 3M leverages its adhesive technology into numerous products like picture hangers, duct tape, and toilet paper holders.

The stationery and office division has a narrow but weakening moat; it earns strong returns, but incremental returns on invested capital should trend downward as the world becomes increasingly digital. Brands like Post-it hold dominant global mindshare, but we believe private labels and consumer trade-down activity have eroded the pricing power of many 3M consumer products.

3M’s legacy portfolio remains highly profitable and is poised to benefit from multiple secular growth trends, such as a growing global middle class and rising regulatory standards.

The firm’s asset utilization should improve as it works to cut excess operating costs and optimize production at underutilized manufacturing plants.

Costs associated with PFAS litigation are already baked into 3M’s share price, and ensuing declines below our fair value estimate could offer an attractive entry point into the stock.

Multibillion-dollar pending litigation risks will cripple the value of the company and remove any benefit from potential fundamental catalysts.

Management has indicated that the company is looking to sell through more distributors, which could raise customer concentration, create distance to the end customer (therefore stifling innovation), and reduce margins.

Without its healthcare segment, 3M will grow far more slowly, as many of its mature businesses are nearing or already experiencing secular decline.
