3M investors received some welcome news this week with the company's strong earnings report, but the specter of "forever chemicals" litigation continues to haunt its stock.
And if the chemicals known as PFAS are deemed hazardous by the federal government — a greater possibility under new President Joe Biden and a Democratic Congress — 3M's legal woes could grow.
"We expect PFAS concerns to continue weighing on the stock … particularly after the Blue Wave scenario came true," Deutsche Bank analyst Nicole DeBlase wrote in a research note this week, referring to Democratic election victories.
Such concerns are common among stock analysts, even though many were enthused that the company's fourth-quarter profits handily exceeded forecasts and that 3M's prospects for 2021 appear much improved.
3M has long been a leading maker of per- and polyfluoroalkyl substances, or PFAS, a family of chemicals used in products from fabric protectors to firefighting foam. But the chemicals don't break down in the environment and have been linked to a host of diseases.
3M stopped making two controversial PFAS compounds — PFOA and PFOS — in 2002.
The Maplewood-based manufacturing giant has been hit with a landslide of lawsuits over its past PFAS production, including one that led to an $850 million settlement in 2018 with the state of Minnesota.
3M has since earmarked hundreds of millions of dollars more to cover further settlements and court awards, though analysts believe the final tab could be several billion dollars.
