3M has established a $4.25 billion unsecured revolving credit facility with JPMorgan Chase Bank as administrative agent. The new facility, dated 17 August 2026, replaces a previous $4.25 billion five-year agreement from May 2023. Advances will mature five years from the effective date, with options to extend for up to two additional one-year periods subject to lender approval. Interest rates vary based on currency and the company's credit rating. The agreement includes provisions allowing 3M to increase the facility up to $5.25 billion in $25 million increments. The company must maintain an EBITDA to Interest Ratio of at least 3.0 to 1.0 quarterly.

3M, the company known for Post-it notes and Scotch tape, has developed expanded beam optical connectivity technology that helps data centre operators deploy fibre-optic networks faster for AI workloads. The technology saves 85% of installation time by spreading light across a wider surface, making connections more resistant to dust and vibrations. Microsoft has certified the technology for use in its Azure data centres after several years of testing. 3M is conducting trials with other hyperscalers whilst expanding manufacturing capacity. The business is expected to generate $40 million to $50 million in revenue this year but could grow four to five times over the next several years. 3M plans to double production capacity this year and again over the following 12 to 18 months.
