3M Q3 2026 Earnings: Margin Expansion and Data-Center Momentum Offset Uneven End Markets

3M reported third-quarter sales of $6.6B and GAAP EPS of $2.63, up 1% and 70% year over year, respectively. On an adjusted basis, organic sales increased 3.3%, adjusted operating margin expanded 110 basis points to 26.2%, and adjusted EPS rose 12% to $2.50.

The quarter reinforced that 3M’s operational turnaround is producing better profitability and improving demand in its core industrial and safety businesses. The more consequential strategic development was the expansion of 3M’s optical-connectivity relationship with Amazon, although the associated $6B sales threshold is a multiyear performance target rather than contracted revenue.

Earnings Snapshot

3M changed its non-GAAP presentation in the quarter to exclude acquired-intangible amortization from adjusted results. The company said the change added approximately 40 basis points to adjusted operating margin and $0.04 to adjusted EPS, with prior periods recast on the same basis.

The Bigger Story

3M’s headline reported organic growth of 0.2% understates the operating momentum in the continuing portfolio because it includes the effect of exiting manufactured PFAS products. Excluding that business, adjusted organic growth was 3.3%, led by Safety and Industrial, where organic sales rose 7%.

The company is also beginning to link its innovation and commercial initiatives to measurable outcomes. Management cited 87 new product launches in the quarter, up 24% year over year, and said sales from products introduced in the last five years increased 34% year to date to nearly $3B. Cross-selling wins booked year to date reached $140M, with another $120M in the pipeline.

The central question is whether these improvements can support sustained growth while 3M absorbs ongoing PFAS-related cash costs, exits legacy product lines, and manages uneven conditions in consumer electronics and China. The company’s better margins and higher full-year EPS outlook suggest progress, but some of the strongest prospective growth opportunities, particularly expanded-beam optical connectivity, remain early in their commercial ramp.

Revenue and Operating Performance

Safety and Industrial was the primary growth engine. Sales increased 9.1%, including 7% organic growth, driven by commercial execution, pricing, new products, and the acquisition of Madison Fire & Rescue. Electrical Markets continued to grow at a double-digit rate as it expanded sales to data-center customers, while Personal Safety, Industrial Adhesives and Tapes, Abrasives, and Industrial Specialties posted high-single-digit growth collectively.

Fire Safety and Rescue revenue nearly doubled to $206M, from $108M a year earlier, reflecting the Madison acquisition. Management said the combined Madison and self-contained breathing apparatus operation produced high-single-digit pro forma growth and margins above both its acquisition model and 3M’s overall margin level. However, management also said the transaction is expected to be EPS-neutral in 2026 and 2027 because higher operating profit is offset by interest expense and noncontrolling-interest impacts.

Transportation and Electronics grew only 0.5% organically. Consumer electronics declined by the mid-teens, reflecting weakness in LCD displays and China-based device manufacturers. That pressure was partly offset by roughly 5% growth across semiconductors, data centers, aerospace, commercial branding, and automotive-related businesses outside consumer electronics.

Electronics segment revenue fell to $616M from $668M, while Advanced Materials sales increased 17% to $175M. Automotive and Aerospace sales were essentially flat at $490M as softer auto production offset double-digit aerospace growth supported by defense, civil aviation, and space-material demand.

Consumer revenue declined 0.2% organically and 0.4% in total. U.S. point-of-sale growth exceeded 2%, but a few major retailers continued to reduce inventory, causing U.S. sell-in to decline at a low-single-digit rate. International consumer sales grew at a mid-single-digit rate.

Geographically, adjusted organic growth was strongest in the United States, up 7.0%, and Latin America, up 7.7%. China remained weak, with adjusted organic sales down 7.3%, while adjusted growth in Europe, the Middle East, and Africa was 1.0%.

Profitability and Margins

Adjusted operating margin reached 26.2%, up 110 basis points from 25.1% a year earlier. The company said its three operating segments collectively delivered 140 basis points of expansion, partly offset by a 30-basis-point drag from corporate costs.

Management attributed the improvement to pricing, productivity, procurement savings, higher asset utilization, lower downtime, and better quality. Gross margin improved 230 basis points, while management said the cost of poor quality improved by 40 basis points and overall equipment effectiveness improved by 20 basis points.

Adjusted operating profit increased by $140M. Management attributed $260M of benefit to sales growth and productivity, partly offset by roughly $120M of stranded costs and investments. The company expects $225M of investments and $150M of stranded costs in 2026, with $125M of that combined amount expected in the fourth quarter.

GAAP results were more affected by special items. GAAP diluted EPS of $2.63 included a $0.60 per-share benefit from the change in value of 3M’s retained Solventum ownership interest. That benefit was partly offset by $0.19 per share of litigation and PFAS-exit costs, $0.20 per share of amortization and acquisition-related costs, and $0.08 per share of transformation costs.

The difference matters because adjusted EPS growth of 12% better reflects the underlying operating result than the 70% increase in GAAP EPS. Still, the reported GAAP operating margin also improved materially, rising 150 basis points to 23.7%.

Demand, Customers and Pricing

Management said order growth was about 7% in the quarter, while backlog entering the fourth quarter was up roughly 18% year over year. About 25% of fourth-quarter revenue is in backlog, modestly above normal levels, supporting management’s confidence in a fourth-quarter acceleration.

Pricing was a meaningful contributor to growth. Management expects price realization to be slightly above 1.5 points for the full year, with second-half pricing slightly above 2 points after roughly 1 point in the first half. The company said it has offset rising material and oil costs through targeted price actions rather than across-the-board increases.

Oil-related inflation is now expected to be $185M for the year, above the prior $150M to $175M estimate. Management expects the associated pricing to fully offset this cost pressure in dollars, although the pass-through is expected to dilute margin rate by approximately 20 basis points. Management expects productivity gains to mitigate that rate effect.

Optical Connectivity and Data Centers

3M’s expanded commercial relationship with Amazon is strategically significant, but investors should distinguish the framework from current revenue. 3M issued Amazon a warrant to purchase up to 3.2 million shares, or about 0.6% of 3M’s common stock, contingent on achieving $6B in cumulative sales of optical connectivity and other data-center products over seven years, along with other milestones.

Management clarified that the agreement does not include volume commitments. The warrant begins to vest in increments as performance thresholds are met, with management expecting activity to begin ramping toward the end of 2027 and become more meaningful in 2028.

Expanded Beam Optics, or EBO, is expected to generate roughly $40M of revenue in 2026. Management expects that amount to approximately double, potentially reaching $80M to $100M, in 2027. 3M has doubled internal EBO manufacturing capacity to more than 10 million ferrules annually and believes its manufacturing partnership with GSEO provides sufficient capacity to serve current expected demand. Further supply partners may be added to meet hyperscalers’ preference for a diversified supply base.

Overall data-center revenue is expected to be about $700M in 2026, up from roughly $550M in 2025. Most current revenue is outside the data center, including electrical connections and medium-voltage infrastructure, while EBO represents an earlier-stage opportunity inside data centers.

What Is 3M’s Guidance for Full-Year 2026?

3M raised adjusted EPS guidance to $9.10 to $9.15, from a prior range of $8.95 to $9.10 on the new reporting basis. The revised range implies 11% to 12% growth from 2025 adjusted EPS of $8.20.

Management’s full-year 2026 guidance includes:

• ·Adjusted total sales growth of more than 4.5%
• ·Adjusted organic sales growth of more than 3.5%
• ·Adjusted operating margin of approximately 24.6%
• ·Adjusted EPS of $9.10 to $9.15
• ·Adjusted operating cash flow of approximately $5.9B
• ·Adjusted free cash flow of approximately $4.8B
• ·Adjusted effective tax rate of approximately 20%

Management expects fourth-quarter organic growth to be just above 4%, aided by backlog conversion and easier comparisons. It expects Transportation and Electronics to reaccelerate despite continued mid-teens weakness in consumer electronics, supported by semiconductors, data centers, aerospace, commercial branding, and recent automotive wins.

For 2027, 3M did not provide formal guidance. Management said it expects growth in line with its second-half 2026 exit rate and operating margin above its prior Investor Day target of 25.4% on the new basis.

Balance Sheet, Cash Flow and Capital

Operating cash flow was $486M in the quarter, down from $1.8B a year earlier. The decline largely reflected working-capital timing and significant litigation and PFAS-exit cash payments. Management expects working-capital timing to reverse in the fourth quarter.

Adjusted free cash flow was $1.2B, down modestly from $1.3B a year earlier. The adjusted figure excludes $894M of after-tax cash impacts from significant litigation and PFAS-exit items during the quarter. The company reported approximately $1B of pre-tax net cash payments tied to litigation and the PFAS exit in the period.

Cash and cash equivalents ended the quarter at $4.8B, down from $5.2B at year-end 2025. Short-term borrowings and current maturities of long-term debt increased to $2.4B from $1.7B, while long-term debt rose to $12.6B from $10.9B. The company spent $1.9B on acquisitions during the first nine months, including Madison Fire & Rescue.

3M returned $600M to shareholders in the quarter, including $400M in dividends and $200M in repurchases. Year-to-date shareholder returns totaled $4.4B, including $3.2B in repurchases. Shares outstanding declined to 516.7 million at quarter-end from 530.3 million at the end of 2025.

What Investors Should Watch

1. Conversion of Industrial Backlog Into Fourth-Quarter Growth

Orders grew about 7% and backlog entering the fourth quarter was up roughly 18%. Delivering organic growth above 4% in the fourth quarter would support management’s claim that core industrial and safety momentum is becoming more durable.

2. Consumer Electronics and China

Consumer electronics declined by the mid-teens and China adjusted organic sales fell 7.3%. Stabilization in premium devices, display films, and Chinese demand would reduce a significant drag on the Transportation and Electronics segment.

3. Margin Durability Amid Inflation and Transformation Spending

Adjusted margin expansion was strong, but 3M still expects incremental stranded costs and investments in the fourth quarter. Investors should monitor whether productivity and price realization continue to offset oil inflation, investment spending, and the remaining $50M increase in expected stranded costs for 2027.

4. EBO Commercial Adoption Rather Than Capacity

3M has expanded capacity and added GSEO as a manufacturing partner. The larger execution test is whether hyperscalers standardize and deploy EBO at scale. The Amazon relationship establishes a substantial performance target, but it does not guarantee sales volumes.

5. PFAS and Litigation Cash Requirements

Third-quarter operating cash flow was heavily affected by litigation and PFAS-exit payments. Adjusted free cash flow remains strong, but reported cash generation, debt levels, and the pace of future settlement-related payments remain important to the capital-allocation case.

AlgovestIQ Takeaway

3M’s third quarter was stronger than the reported 1% sales growth initially suggests. Excluding the manufactured PFAS business that 3M exited, adjusted organic growth reached 3.3%, with Safety and Industrial posting 7% organic growth. Margin expansion was also broad-based and appears tied to operational improvements rather than a one-time accounting benefit.

The company’s raised EPS guidance and confidence in a fourth-quarter acceleration indicate that order rates and backlog remain constructive. Pricing has helped offset higher oil and material costs, while operational actions are contributing to better gross margins and higher incremental profitability.

The more speculative element of the investment case is data-center optical connectivity. The Amazon warrant and GSEO manufacturing relationship validate 3M’s strategic positioning in EBO, but the $6B cumulative-sales threshold over seven years is an objective to earn, not a committed purchase volume. EBO revenue remains small in 2026 and is expected to remain below $100M in 2027.

The central investment question is whether 3M can convert its improving execution into sustainable organic growth above its historical trend while preserving margin gains and managing litigation-related cash demands. Continued growth in industrial, safety, semiconductors, aerospace, and data-center infrastructure would strengthen that case. Renewed weakness in China or consumer electronics, a failure to sustain pricing and productivity, or higher-than-expected PFAS-related cash obligations would challenge it.
