3M CO

3M is a diversified global manufacturer, technology innovator and marketer of a wide variety of products and services.

As discussed in Note 1, certain changes are reflective in this document for all applicable periods presented. Effective in the first and second quarters of 2026, the Company made changes to the measure of segment operating performance and segment composition used by its CODM, impacting the disclosed measure of segment profit (business segment operating income). Further details are provided in Note 16.

3M manages its operations in three operating business segments: Safety and Industrial; Transportation and Electronics; and Consumer. From a geographic perspective, "EMEA" refers to Europe, the Middle East, and Africa on a combined basis.

Unless otherwise noted, all year-over-year ("YoY") comparisons in this MD&A refer to the second quarter and the first six months of 2026 compared with the second quarter and first six months of 2025.

Financial highlights for the second quarter and the first six months of 2026:

(a) The Company refers to various "adjusted" amounts or measures on an “adjusted" basis. These exclude special items. These non-GAAP measures are further described and reconciled to the most directly comparable GAAP financial measures in the Certain amounts adjusted for special items - (non-GAAP measures)section below.

(b) Organic sales change (which includes both organic volume and selling price impacts), is defined as the change in net sales, absent the impacts from foreign currency translation and acquisitions, net of divestitures. 3M believes this information is useful to investors and management in understanding ongoing operations and in analysis of ongoing operating trends.

Net sales change was driven by strength in industrial, safety, semiconductor and data center—supported by commercial excellence and innovation. This strength was partially offset by weakness in consumer/consumer electronics, and the YoY impact of the manufactured PFAS products special item.

GAAP operating margins were affected by the YoY impact of special items. The primary drivers were higher losses on business divestitures, and transformation costs. These drivers were partially offset by lower net costs for significant litigation and PFAS exit, which on a year-to-date basis reflect increased insurance recoveries (discussed in Note 15).

Outside of special items, both GAAP and adjusted operating margins reflect benefits from growth, productivity, and favorable foreign currency impacts, partially offset by tariff impacts, cost dis-synergies (following the exit of PFAS manufacturing and the 2024 spin of Solventum), and growth investments.

GAAP EPS YoY was affected by the net impact of special items, including those impacting operating income discussed above, as well as by the impact of changes in Solventum's share price (which was a YoY benefit in the second quarter and YoY headwind in the first six months of 2026).

Outside of special items, both GAAP and adjusted EPS reflect the operating margin drivers discussed above, while non-operating benefits were primarily driven by a lower share count. On a year-to-date basis, EPS also benefited from favorable tax timing.

3M completed its exit of PFAS manufacturing by the end of 2025. As discussed in Note 15, the Company continues to address PFAS manufactured prior to exit through treatment, remediation, and disposition of its assets and interests in manufacturing facilities, which may include dismantling, cleaning, and repurposing. Decisions or circumstances associated with the extent and type of remaining activity at particular locations and impacts on assets and potential obligations, among other factors, could result in additional expenses.

Additional information regarding certain items impacting pre-2026 periods that may also be relevant in 2026 can be found in the Overview section of Part II, Item 7 as well as in further sections of 3M’s 2025 Annual Report on Form 10-K.
