OPINION OF THE COURT

Joshua Johnson appeals the Fed.R.Civ.P. 12(b)(6) dismissal of his civil RICO action. We will affirm.

I.

Johnson’s claim arises out of a series of power struggles within the International Brotherhood of Teamsters, AFL-CIO. Johnson was a member of IBT Local 115. He was employed as Organizing Representative in January 1999, when he brought information about the alleged racketeering activities of several other members to the attention of John Moms, the principal officer of Local 115. Johnson alleged that various union members violated statutes related to trafficking in contraband cigarettes, operating and supervising illegal gambling activities, fraudulently charging Local 115 for “rehabilitation services,” and trafficking in controlled substances. Beginning around January 1999 and upon Morris’s direction, Johnson investigated these allegations, over a seven-month period.

On November 15, 1999, James P. Hoffa, General President of the IBT, imposed an emergency trusteeship over Local 115 and removed Morris as principal officer. Johnson was terminated from his employment both as organizing representative with the union and as an employee at Electro-Nite, a union shop, after the trusteeship was imposed and after appellees reviewed the files connected to Johnson’s investigation. Johnson alleges that shortly thereafter, various appellees intimated, physically assaulted, and extorted him.

Johnson brought this action seeking damages under 18 U.S.C. § 1964(c). 1 Johnson contends the Teamsters engaged in a pattern of racketeering activity and a conspiracy directed at removing Morris as the principal officer of Local 115 in order to impose a trusteeship. He argues the Teamsters’ alleged racketeering activity and Morris’ removal harmed Johnson’s property interests in his employment, his reputation, and his membership in a racketeer-free union. The District Court granted appellees’ Rule 12(b)(6) motion to dismiss, holding Johnson’s did not have standing under § 1964(c), both because Johnson’s job loss did not occur “by reason of’ the Teamsters’ racketeering activity, and because his property interests in his reputation and membership in a racketeer-free union are not interests RICO protects. Johnson appeals, claiming the District Court erred in its standing determination. 2

II.

We exercise plenary review over the District Court’s grant of a motion to dis *90 miss for failure to state a claim. Lum v. Bank of Am., 361 F.3d 217, 223 (3d Cir. 2004). On an appeal from a Rule 12(b)(6) dismissal, we treat all of the allegations in the plaintiffs complaint as true. Anderson v. Ayling, 396 F.3d 265, 267 (3d Cir. 2005). Johnson’s claim may only be dismissed “if it is clear that no relief could be granted under any set of facts that could be proved consistent with the allegations.” Lum, 361 F.3d at 223. But we “need not accept as true unsupported conclusions and unwarranted inferences.” Doug Grant, Inc. v. Greate Bay Casino Corp., 232 F.3d 173, 184 (3d Cir. 2000). We also exercise plenary review over the District Court’s determination that Johnson lacked standing to pursue his claims under 18 U.S.C. § 1964(c). See Maio v. Aetna, Inc., 221 F.3d 472, 482 (3d Cir. 2000).

III.

Johnson challenges the District Court’s determination that his job loss did not occur “by reason of’ the Teamster’s racketeering activity. To maintain a civil RICO action, Johnson must show proximate causation between appellees’ RICO violations and his injuries. See Holmes v. Sec. Investor Prot. Corp., 503 U.S. 258, 268, 112 S.Ct. 1311, 117 L.Ed.2d 532 (1992). But “injury caused by an overt act that is not an act of racketeering or otherwise wrongful under RICO ... is not sufficient to give rise to a cause of action under § 1964(c) for a violation of § 1962(d).” Beck v. Prupis, 529 U.S. 494, 505, 120 S.Ct. 1608, 146 L.Ed.2d 561 (2000). For an overt act to qualify as “an act of racketeering or otherwise wrongful under RICO,” that act must be “independently wrongful” under some “substantive provision” of the RICO statute. Id. at 505-06, 120 S.Ct. 1608. An allegation that a plaintiff is injured “merely by a non-racketeering act in furtherance of a broader RICO conspiracy” is insufficient to confer standing under the statute. Anderson, 396 F.3d at 269.

Johnson’s allegations do not directly link a substantive RICO violation to his loss of employment. Johnson contends appellees terminated his employment after reviewing files related to his investigation of corruption and racketeering activity. Properly understood, Johnson does not claim the act of termination was itself “independently wrongful” under any of RICO’s substantive provisions — rather, he claims the act of termination was related to an overall RICO conspiracy and was intended to further that conspiracy. But this is precisely the kind of circumstance both Beck and Anderson held would not confer RICO standing on a plaintiff.

In Beck, the plaintiff, an employee at an insurance company, discovered the company’s directors were engaged in racketeering activities. After Beck contacted regulators about the company’s financial statements, the directors falsified a report and used that report to terminate him from his employment. The Supreme Court held that, even though Beck’s job loss was in furtherance of a RICO conspiracy, the racketeering activity did not proximately cause his injury because it was not independently wrongful under any substantive provision of the statute. Beck, 529 U.S. at 506, 120 S.Ct. 1608.

Beck is precisely on point. Like the plaintiff’s injury in Beck, Johnson’s only injury here — his employment termination — was not proximately caused by the appellees’ racketeering activity because it was not independently wrongful under any substantive provision of the RICO statute. 3 *91 Even though Johnson allegedly lost his job in furtherance of appellees’ RICO conspiracy, RICO standing requires more. None of Johnson’s allegations meet the bar set by Beck.

In Anderson, we noted the “possib[ility] that a predicate act of racketeering that directly caused a plaintiff to lose his job could create civil RICO standing.” 396 F.3d at 269-70. But no link between Johnson’s job loss and appellees’ racketeering activities (trafficking in contraband cigarette and controlled substances, operating an illegal gambling business, or fraudulently charging Local 115 for rehabilitation services) is any more direct than was the link between Beck’s job loss and his directors’ racketeering activities. Accordingly, the District Court’s Rule 12(b)(6) dismissal was not error. 4

Johnson also alleges other acts — namely, physical assault, extortion, and mail fraud — apart from the act of termination, which he argues are all related to his job loss. But he could not have been terminated, as he claims, “by reason of’ these “predicate” acts: each act occurred after his employment termination. See Anderson, 396 F.3d at 271 n. 4 (“[Appellants] also accuse the defendants of other acts of racketeering.... These acts cannot, however, have proximately caused their job loss, for the simple reason that they occurred a week after plaintiffs were terminated from Kurz-Hastings.”). 5

IV.

We will affirm the judgment of the District Court.
