3M (NYSE: MMM) faced renewed legal pressure this week as Australia launched a lawsuit seeking more than A$2 billion (approximately $1.43 billion) in damages tied to PFAS contamination at 28 defense sites. The stock dropped 1.5% on Thursday following the announcement, but managed to close the shortened trading week at $153.13, up roughly 0.5% from the previous Friday. U.S. markets were closed Monday for Memorial Day.
The lawsuit, filed by the Australian government, targets 3M and its local subsidiary over pollution linked to firefighting foams containing per- and polyfluoroalkyl substances (PFAS), often called "forever chemicals" due to their environmental persistence. Australia is seeking to recover both past and future costs for investigating, managing, and cleaning up contamination at defense bases. Assistant Defence Minister Peter Khalil noted that the Department of Defence has already spent over A$1.3 billion on its PFAS response.
3M has stated it will fight the case, emphasizing that it never manufactured PFAS in Australia and stopped selling the foams in question there approximately 20 years ago. The company also pointed out that Australia's Department of Defence continued using PFAS-containing firefighting foams for nearly two decades after that. Despite the legal setback, 3M shares showed resilience, gaining 1.04% on Tuesday and 0.74% on Wednesday before Thursday's drop, followed by a modest 0.18% uptick on Friday. Friday's trading volume reached 7.90 million shares, higher than earlier in the week.
This legal action comes at a time when Wall Street indexes were hitting new highs, with the S&P 500 notching its ninth consecutive weekly gain, up 1.43% for the week, and the Dow Jones Industrial Average rising 0.9%. However, 3M's performance was more influenced by its own liability concerns than the broader market rally. The company's PFAS litigation risk remains a key overhang, even as it reported stronger quarterly results. For the first quarter, 3M posted adjusted earnings per share of $2.14, up 14% year-over-year, on adjusted sales of $6.0 billion. Organic sales grew 1.2%, and the company maintained its 2026 adjusted EPS guidance of $8.50 to $8.70.
CEO Bill Brown expressed optimism about the year ahead, stating during the April earnings call that "Q2 being better than Q1" is expected, with a stronger second half anticipated. CFO Anurag Maheshwari projected more than 3% organic growth in the second quarter, citing backlog and order momentum. However, the company faces headwinds from higher oil-related costs, which Brown estimated at about $125 million, and is working to offset these through price hikes. The impact on consumer spending and autos remains "still unfolding," Brown noted.
PFAS litigation is not unique to 3M. In 2023, Chemours, DuPont, and Corteva reached a $1.19 billion settlement with most U.S. public water systems facing PFAS suits, while 3M agreed to a separate $10.3 billion deal over similar claims. These ongoing legal battles continue to move chemical and industrial stocks, even when headline numbers appear manageable relative to larger balance sheets. Investors are now closely watching the upcoming U.S. employment report due June 5, with economists polled by Reuters expecting 85,000 jobs added and an unemployment rate of 4.3%. A strong jobs report could influence Federal Reserve policy, while a weaker reading might ease concerns about tightening.
3M's next investor event is scheduled for June 10, when CEO Bill Brown will present at the Wells Fargo Industrials & Materials Conference at 8:45 a.m. CT. Market participants will be listening for comments on demand, pricing, and any updates on PFAS litigation. The key risks for the stock include larger-than-expected PFAS costs, higher input prices from oil, weakness in consumer electronics, and a potential hot jobs report that could lift bond yields. Despite these challenges, 3M's recent quarterly performance and guidance suggest underlying operational strength, even as legal clouds persist.
