INTRODUCTION Plaintiffs City and County of Butte-Silver Bow, Montana (“Butte-Silver Bow” or “BSB”), Santa Monica, California (“Santa Monica”), City of Stamford, Connecticut (“Stamford”), Old Mystic Fire District, Connecticut (“Old Mystic”), Mayor and City Council of Baltimore, Maryland (“Baltimore”), Charles County,

Maryland (“Charles County”), City of St. Louis, Missouri (“St. Louis”), Kansas City, Missouri (“Kansas City”), Anniston, Alabama (“Anniston”), Little Rock, Arkansas (“Little Rock”), Pine Bluff, Arkansas (“Pine Bluff”), Markham, Illinois

(“Markham”), Gary, Indiana (“Gary”), Worcester, Massachusetts (“Worcester”), Borough of Emmaus, Pennsylvania “(Emmaus”), and City of Oak Creek, Wisconsin (“Oak Creek”) (collectively “Plaintiffs”) filed a Second Amended Complaint (“SAC”) against Defendants 3M Company (“3M”), Dupont De Nemours, Inc., The

Chemours Company, The Chemours Company FC, LLC, Corteva, Inc. (“Dupont”), Globe Manufacturing Company LLC (“Globe”), W.L. Gore & Associates, Inc. (“Gore”), Lion Group Inc. (“Lion”), Fire-Dex LLP (“Fire-Dex”), Morning Pride

Manufacturing LLC (“Morning Pride”), Innotex Corp. (“Innotex”), and EIDP Inc. (f/k/a E.I. Dupont De Nemours and Company) (“EIDP”) (collectively “Defendants”) on May 5, 2026. (Doc. 234.) Defendants filed motions to dismiss Plaintiffs’ SAC. (Doc. 308, Doc. 311, Doc. 313, Doc. 315, Doc. 317, and Doc. 378.) Plaintiffs oppose

the motions. (Doc. 338.) The Court held a hearing on the matter on July 9, 2026. (Doc. 373.) BACKGROUND Plaintiffs bring this nationwide class action against Defendants for the alleged sale, manufacture, and distribution of protective firefighter gear (“turnout gear”)

containing per- and polyfluoroalkyl substances (“PFAS”) to fire departments and fire responding agencies. (Doc. 234 ¶¶ 1-9.) Plaintiffs allege PFAS, found in the firefighter turnout gear, are associated with serious health effects, including cancer.

(Id.) Plaintiffs contend that Defendants concealed the known dangers of PFAS and failed to provide adequate safety warnings to the public and class members, despite having knowledge of the risks and harms of PFAS for decades. (Id. ¶¶ 10-12.) Plaintiffs assert that the ineffective safety warnings render the products defective

and unreasonably unsafe. (Id.) Plaintiffs allege that Defendants worked together to conceal the known dangers of PFAS from Plaintiffs and the public. (Id. ¶ 11.) Plaintiffs allege that Defendants’ failure to warn of the harms from PFAS caused

foreseeable injuries to class members who used turnout gear as intended. (Id.) Plaintiffs comprise cities, counties, municipalities, and one fire district across the United States. (Id. ¶¶ 21-121.) Plaintiffs’ claims arise under the Racketeer and Corrupt Organization Act (“RICO”) and various state laws. (Id. ¶ 20.) Plaintiffs seek

monetary damages to replace the defective turnout gear purchased. (Id. ¶¶ 19-20.) Plaintiffs originally brought claims in separate cases in the District of Montana and the District of Connecticut. (See Doc. 190; see Uniformed Pro. Fire

Fighters Ass’n v. 3M Co., No. 3:24-cv-01101 (D. Conn.) (“UPFFA”).) Plaintiff Butte Silver-Bow filed the action in the District of Montana on April 3, 2025. (Doc. 1.) Defendants filed motions to dismiss Plaintiff Butte Silver-Bow’s Complaint

(Doc. 1). (Doc. 100, Doc. 103, Doc. 105, and Doc. 107.) The Court denied Defendants’ first round of motions to dismiss Plaintiff Butte Silver-Bow’s Complaint. (Doc. 159.)

Plaintiff Butte Silver-Bow amended its complaint on March 13, 2026, to add new Plaintiffs including Santa Monica, Stamford, Old Mystic, Baltimore, Charles County, and St. Louis. (Doc. 190.) The First Amended Complaint (“FAC”) additionally added three new Defendants including EIDP, Fire-Dex, and Morning

Pride. (Id.) Defendants filed a second round of motions to dismiss. (See Doc. 193, Doc. 198, Doc. 200, and Doc. 202.) Plaintiffs filed a Second Amended Complaint (“SAC”) on May 5, 2026, adding several new Plaintiffs including the following:

Kansas City, Anniston, Little Rock, Pine Bluff, Markham, Gary, Worcester, Emmaus, and Oak Creek; along with one new Defendant, Innotex. (Doc. 234.) The Court denied as moot Defendants’ second round of motions to dismiss. (Doc. 252.) Defendants’ third round of motions to dismiss assert several grounds to argue

for dismissal of Plaintiffs’ various claims. (Doc. 308, Doc. 311, Doc. 313, Doc. 315, Doc. 317, and Doc. 378.) Defendants seek to dismiss all Plaintiffs’ claims alleged in the SAC pursuant to Fed. R. Civ. P. 12(b)(6). (Id.)

LEGAL STANDARD Rule 8(a)(2) of the Federal Rules of Civil Procedure requires claimants to include in their complaint “a short and plain statement of the claim showing that the

pleader is entitled to relief.” A motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) tests the legal sufficiency of a complaint under the plausibility pleading standard of Rule 8(a)(2). See Navarro v. Block, 250 F.3d 729, 732 (9th Cir.

2001). Dismissal proves appropriate under Rule 12(b)(6) where the complaint fails to state a claim upon which relief can be granted. Mendiondo v. Centinela Hospital Med. Ctr., 521 F.3d 1097, 1104 (9th Cir. 2008). A court may dismiss a complaint “based on the lack of a cognizable legal theory or the absence of sufficient facts

alleged under a cognizable legal theory.” Balistreri v. Pacifica Police Dep’t, 901 F.2d 696, 699 (9th Cir. 1988). A complaint must contain sufficient factual matter to state a plausible claim

for relief on its face to survive a Rule 12(b)(6) motion. Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). A claim proves plausible on its face when “the plaintiff pleads factual content that allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Id. The plausibility standard does

not require probability, but “asks for more than a sheer possibility that a defendant has acted unlawfully.” Id. A court must “take[] as true and construe [] in the light most favorable to plaintiffs” all factual allegations set forth in the complaint. Lee v. City of Los Angeles, 250 F.3d 668, 688 (9th Cir. 2001) (internal quotation marks omitted).

DISCUSSION Defendants seek to dismiss Plaintiffs’ claims contained in the SAC on various grounds. Defendants assert that the Court lacks personal jurisdiction over
