Acquisitions and Divestitures

Acquisitions, Redeemable Noncontrolling Interest and Divestitures

Refer to Note 4 to the Consolidated Financial Statements in 3M's 2025 Annual Report on Form 10-K for more information on relevant pre-2026 acquisitions and divestitures.

Previously Announced Acquisition:

In July 2026, 3M, in partnership with Bain Capital ("Bain"), completed the acquisition of Madison Fire & Rescue ("Madison") for $ 1.95 billion, subject to closing and other adjustments.

Acquisition and Redeemable Noncontrolling Interest:

In July 2026, 3M, in partnership with Bain Capital ("Bain"), completed the acquisition of Madison Fire & Rescue ("Madison") for $ 1.9 billion, subject to closing and other adjustments, net of cash acquired.

Madison offers a portfolio of rescue technology and fire-suppression products.

Under related agreements, 3M and Bain established a venture to which 3M contributed its self-contained breathing apparatus business ("SCBA") and Bain contributed cash.

The venture utilized the contribution and purchased Madison, while drawing on its term loan facility.

3M will consolidate the venture, of which it owns 50.1 %.

On a consolidated basis, 3M received net proceeds of approximately $ 0.7 billion in the third quarter of 2026 from closing of the transactions, reflecting proceeds from the term loan facility and Bain's contribution, net of amounts used to acquire Madison.

Madison will be combined with SCBA within 3M's Safety and Industrial segment.

Bain's noncontrolling interest is redeemable after five years , will be presented outside of permanent equity in the consolidated balance sheet and measured at the greater of its initial carrying amount updated for its share of earnings or estimated redemption value, affecting net income attributable to 3M.

Features of Bain's interest, along with other venture exit and liquidity provisions, also result in a derivative instrument that will be carried at fair value.

Given the acquisition's close on July 1, 2026, 3M will provide preliminary amounts recognized for major classes of assets acquired and liabilities assumed, including intangible assets and goodwill, in the third quarter.

Under related agreements, 3M and Bain established a venture as further discussed below.

The allocation of purchase consideration related to Madison is considered preliminary with provisional amounts primarily related to intangible assets, working capital, and certain tax-related and liability amounts.

3M expects to finalize the allocation of purchase price within the one-year measurement-period following the acquisition.

Net sales of the Madison business included in the Company’s Safety and Industrial segment for the third quarter of 2026 were approximately $ 90 million and operating income was not significant.

Proforma information related to the acquisition was not considered material.

The following table shows the preliminary amounts recognized for major classes of assets acquired and liabilities assumed, which are subject to adjustment as 3M obtains additional information during the measurement period.

Asset/(liability) (millions, except weighted average lives) Madison Finite-lived intangible asset weighted average lives (years)

Supplemental information:

Cash paid, net of cash acquired $ 1,910

The amount of goodwill expected to be deductible for tax purposes was not material.

Under agreements related to the acquisition of Madison, 3M and Bain established a venture into which 3M placed its self-contained breathing apparatus business ("SCBA") and Bain contributed approximately $ 1.3 billion of cash.

The venture utilized the contribution and drew on its term loan facility (as discussed in Note 11) to purchase Madison.

3M has 50.1 % of the venture's voting interest and consolidates it under the variable interest entity model.

SCBA's historical activity (previously part of the Personal Safety division) together with the new activity of Madison beginning in July 2026 are reflected as the Fire Safety and Rescue division (also referred to as 3M Sentorum) within the Safety and Industrial segment.

The venture results in 3M reflecting a redeemable noncontrolling interest ("RNCI").

Bain's interest is puttable to 3M five years after venture formation (making it redeemable) and callable by 3M at fair value, subject to floors and caps based on multiples of each party's initial investment.

Bain's interest also includes floor return rights in the event of sale or public offering of the venture.

The RNCI is presented outside of permanent equity on 3M's consolidated balance sheet.

These features also result in 3M reflecting a derivative liability for Bain's net put right, which is carried at fair value as described in Note 13.

The RNCI is measured at the greater of its initial carrying amount updated for its share of earnings or losses, or estimated redemption value after considering the value of the separate derivative.

Adjustments for changes in estimated redemption value of the RNCI are recognized as they occur, reflected in retained earnings, and affect net income attributable to 3M common shareholders.

See Note 8 for activity and changes in carrying amount of the RNCI.

Distributions from the venture are subject to approval of both 3M and Bain.

At September 30, 2026, approximately $ 0.9 billion of net assets on 3M's consolidated balance sheet are 3M's proportional interest in those of the venture.

Divestitures:

In April 2026, 3M completed the sale of its precision grinding and finishing business, formerly within the Safety and Industrial business.

In the second quarter of 2026, 3M completed the sale of its precision grinding and finishing business, formerly within the Safety and Industrial business.

This business was classified as held for sale in the third quarter of 2025.

3 unchanged sentences

The Flemish government's confirmation was judicially appealed by a Belgian non-profit organization.

3M Belgium cannot predict the outcome of such judicial appeal and is therefore unable to assess whether the current Zwijndrecht Facility wastewater treatment system, or currently conceived additional treatment technology, will be able to meet the ultimately determined permit limits with respect to ongoing non-PFAS manufacturing at the Zwijndrecht Facility.

It is possible that the outcome of the appeal or future permit amendments will alter discharge limits and will require additional actions to reduce legacy sources of PFAS, or that the wastewater treatment system there will be unable to meet future discharge limits.

If 3M Belgium is unable to meet the eventual discharge limits, it could have a significant adverse impact on 3M Belgium's normal operations and the Company's businesses that receive products and other materials from the Zwijndrecht Facility, some of which may not be available or available in similar quantities from the Company's other facilities, which could in turn impact these businesses' ability to fulfill supply obligations to their customers.
