3M (NYSE: MMM) shares climbed 5.43% in after-hours trading on October 19 after the industrial manufacturer announced an expanded strategic agreement with Amazon (NASDAQ: AMZN) covering optical connectivity and other data center products.
Under the agreement, 3M issued warrants to a wholly owned Amazon subsidiary allowing it to purchase up to 3,162,015 shares of 3M common stock at $164.89 per share over seven years.
- Amazon expanded its commercial agreement with 3M, receiving warrants to purchase up to 3.16 mn shares at $164.89 each, representing approximately $521.4 mn in potential equity purchases.
- About 85% of the warrant shares will vest as Amazon purchases optical connectivity and other data center products, with full vesting of that portion tied to $6 bn in cumulative payments.
- 3M is expanding its AI data center business through partnerships with Amazon, Microsoft and Taiwan’s Genius Electronic Optical, as US hyperscaler capital expenditure is projected to approach $1.2 tn in 2027.
The warrants represent approximately $521.4 mn at the stipulated exercise price, although Amazon’s ability to acquire the shares depends on meeting specified commercial and performance conditions.
Amazon shares gained 0.29% in extended trading following the announcement.
Amazon’s $6 bn purchasing threshold determines warrant vesting
According to 3M’s October 19 filing with the US Securities and Exchange Commission, 85% of the warrant shares will vest based on Amazon’s cumulative payments for optical connectivity and other data center products. That portion becomes fully vested once Amazon’s qualifying purchases reach $6 bn.
The remaining 15% will vest upon the achievement of separate event-based milestones. 3M did not disclose the specific conditions governing those milestones.
The agreement links Amazon’s potential equity ownership to the commercial relationship rather than providing an immediate equity stake.
If all warrants become exercisable and Amazon purchases the maximum number of shares, its resulting ownership would represent less than 1% of 3M’s outstanding common stock.
Amazon has previously entered into similar warrant arrangements with suppliers including Generac and Qualcomm, using equity-linked agreements alongside commercial purchasing relationships.
3M expands optical connectivity business for AI data centers
The agreement strengthens 3M’s position as a supplier of components used in hyperscale data centers, where demand for high-capacity connectivity infrastructure has increased alongside spending on artificial intelligence and cloud computing.
3M is developing Expanded Beam Optical (EBO) technology for fiber-optic connections in data centers.
Unlike conventional physical-contact fiber connectors, EBO technology uses an expanded optical beam interface designed to improve tolerance to contamination and reduce installation and maintenance requirements.
The technology is intended to support reliable connections in high-density computing environments, where large numbers of optical interfaces must operate consistently.
In July 2026, 3M announced a strategic partnership with Microsoft (NASDAQ: MSFT) to deploy EBO technology across Microsoft’s Azure data center infrastructure.
Microsoft became the first announced hyperscale cloud provider to adopt the technology for AI data center applications.
The agreement also covers broader collaboration on enterprise technology, with 3M using Microsoft’s AI and digital platforms across selected business functions.
The Amazon filing identifies optical connectivity and other data center products but does not specify which products Amazon will purchase under the expanded arrangement.
3M plans 4.7% investment in Genius Electronic Optical
Separately, 3M announced a collaboration with Taiwan-based Genius Electronic Optical (GSEO) on October 19 to develop and manufacture Expanded Beam Optical solutions.
The companies intend to combine 3M’s materials science and optical connectivity technology with GSEO’s precision optics manufacturing capabilities.
Their work will focus on EBO components, including optical ferrules, co-packaged optics and related interconnect applications for data centers.
3M plans to acquire approximately 4.7% of GSEO’s common shares through a private placement of newly issued stock. The investment is expected to close in the fourth quarter of 2026, subject to customary closing conditions.
The partnership is intended to expand manufacturing capacity and support commercial production of optical components used in hyperscale computing infrastructure.
Hyperscaler capital spending forecast to reach $1.2 trillion
The Amazon agreement comes as major US technology companies increase capital spending on data centers, networking equipment and AI computing infrastructure.
According to estimates cited by Apollo Global Management, US hyperscaler capital expenditure could reach approximately $916 bn over the next 12 months, rising to nearly $1.2 trillion in the following year.
Data center investment is projected to account for approximately 3.1% of US GDP in 2027.
For comparison, telecommunications infrastructure investment peaked at approximately 1.2% of GDP during the late-1990s dot-com expansion.
Apollo chief economist Torsten Slok has noted that the scale of current hyperscaler investment relative to GDP substantially exceeds the peak of the earlier telecommunications infrastructure cycle.
The expenditure forecasts cover broader hyperscaler capital investment and do not represent expected revenue for 3M.
For 3M, the Amazon agreement establishes a direct commercial purchasing threshold of $6 bn for most of the warrant shares, while its Microsoft and GSEO partnerships support the development and production of optical connectivity technology.
The timing and extent of Amazon’s future purchases, and whether all warrant conditions will be satisfied, remain dependent on the terms of the expanded commercial arrangement.
