3M Shares Rise 4.5% Premarket Following Expanded Amazon Agreement and Taiwan Investment Plan

By Fiona Craig | October 20, 2026, 6:34 AM

3M (NYSE:MMM) shares advanced 4.5% in premarket trading on Tuesday after the industrial group announced an expanded commercial relationship with an Amazon subsidiary and disclosed plans to acquire a minority stake in Taiwan-based Genius Electronic Optical Co. (GSEO).

Under the expanded agreement, announced late Monday, 3M issued a warrant granting Amazon the right to purchase up to 3.16 million common shares at an exercise price of $164.89 per share over a seven-year period.

The warrant represents a potential share purchase value of more than $521 million if exercised in full.

Approximately 85% of the warrant shares are subject to vesting conditions linked to Amazon’s cumulative purchases of optical interconnect and other data centre products from 3M. Full vesting of those shares would occur once Amazon’s total qualifying payments reach $6 billion.

The arrangement links a substantial portion of Amazon’s potential equity participation to purchases of products supplied by 3M for data centre applications.

Separately, 3M announced plans to acquire approximately 4.7% of Genius Electronic Optical Co., a Taiwan-based optical technology company, through a private placement.

The proposed investment relates to 3M’s activities in Expanded Beam Optical solutions, which are used in data centre connectivity applications. Financial terms of the planned investment were not disclosed in the supplied announcement.

The two developments were announced against a mixed backdrop for US equity markets. The S&P 500 gained approximately 0.1%, while the Dow Jones Industrial Average advanced 0.3%. The Nasdaq declined 0.3%.

3M shares traded as high as $169.23 in premarket dealings, compared with a reported session opening level of $164.85.

The stock’s 52-week trading range stood between $139.34 and $184.90.

The expanded Amazon agreement establishes a potential equity arrangement tied primarily to future product purchases, while the proposed Genius Electronic Optical investment would give 3M a minority ownership position in the Taiwanese company.
