Plaintiff-appellant Davric Maine Corporation (“Davric”) seeks to overturn a grant of summary judgment in favor of defendants-appellees Craig Rancourt, Ival R. Cianchette, and William Faucher (the “defendants”). 1 Davric contends that a fact-finder reasonably could conclude that the defendants violated federal and state antitrust' laws and tortiously interfered with its contractual relations. We affirm.
Background
Joseph J. Ricci owns a holding company which owns Davric. Davric, in turn, owns *145 and operates Scarborough Downs (“Scarborough”), a harness racetrack in Scarborough, Maine. Scarborough hosts races, which attract horses and gamblers from Maine and other states, and also simulcasts other tracks’ races. The facility is subject to regulation by Maine’s Harness Racing Commission (the “Commission”).
Davric alleges that in 1994, several individuals, including defendants Cianchette, Faucher, and Rancourt, conspired to destroy Scarborough’s business in order to establish a new dominant track or to facilitate a takeover of Scarborough. Cian-chette owned a stake in the only other racetrack in Maine, Faucher was Director of Operations for Foxboro Park in Massachusetts, and Rancourt was an attorney who represented the Mainе Harness Horsemen’s Association (“MHHA”) in dealings with Scarborough. The MHHA, as well as the New England Harness Horsemen’s Association (“NEHHA”), supplied the horses that raced at Scarborough.
Though we believe that summary judgment in the defendants’ favor was fully warranted, we review Davric’s record evidence, as we must, in the light most favorable to it. The following inferences are supportable: In 1994, the defendants agreed that they would act in сoncert to undermine Scarborough’s business and to wrest control of harness racing in southern Maine from Davric. In early 1994, defendant Faucher spoke of these efforts with Lou Giuliano, the president of the NEH-HA, and solicited Giuliano’s help. 2 Faucher informed Giuliano that he and several partners intended to bring about the foreclosure of a mortgage Ricci had taken on Scarborough. Some time later, Faucher told Giuliano that this plan had failed, 3 and that the anti-Davric. group now planned either (1) to persuade the Commission to deny race dates to Scarborough or (2) to “bury [Ricci] in the [Maine] legislature.” According to Giuliano, after this conversation, he also “understood” that Faucher intended the MHHA to be able to prevent its members from supplying horses to Scarborough without other organizations, such as the NEHHA, filling the resulting vоid. 4
Giuliano opted not to participate in the defendants’ plans. Representing the MHHA at a public hearing in late 1994, Rancourt urged that Scarborough be denied racing dates for 1995. The NEHHA did not follow the MHHA’s lead, and Giuli-ano in fact testified in favor of race dates for Scarborough. Rancourt, Cianchette and Faucher all attended this hearing. Immediately following the hearing, Ranc-ourt and Giuliano became invоlved in a verbal altercation concerning Giuliano’s testimony favorable to Davric. 5
In June or July of 1996, approximately two years after the conversations between Faucher and Giuliano, MHHA leaders apparently tried to force member horsemen to boycott Scarborough. 6 As a result, for *146 several days, Davric ran fewer races than it ordinarily would have run.
In March 1997, the MHHA’s Executive Secretary, Ken Ronco, was served with notice to vacate the association’s offices at Scarborough, despite a 1996 contract requiring Davric to provide the MHHA with office space there. Rancourt subsequently filed suit against Davric on behalf of the MHHA, alleging wrongful eviction, conversion of MHHA property, and assault against Ronco. The wrongful eviction and conversion claims were submitted to arbitration pursuant to the 1996 cоntract, and the arbitrator found in favor of the MHHA. The evidence suggests that the assault claim remains pending.
Davric’s summary judgment evidence further suggests that the defendants have continued to pursue business interests adverse to Davric’s in furtherance of the purported conspiracy. For instance during 1994, Cianchette apparently negotiated with third parties to establish a new racing location in Southern Maine. In 1997, Ranсourt urged horsemen to frequent racetracks other than Scarborough. That year, with Rancourt’s help, the MHHA formed a “Steering Committee” to investigate opportunities for establishing a competitor track. Faucher was named to the committee, as was Cianchette’s son. Rancourt then proposed to the Maine legislature measures designed to facilitate the formation of the new track. Later in 1997, these efforts resulted in the enactment of such legislation.
, On June 24, 1998, based on the foregoing claims, Davric filed suit in federal district court against Rancourt, Cianchette, Faucher, Joseph M. Molnar, and Ken Ron-co. Davric charged that the defendants had violated federal and state antitrust laws and tortiously interfered with Dav-ric’s contractual relations. The defendants moved for summary judgment on all counts. A magistratе judge recommended that summary judgment be granted, and the district court concurred. Davric appeals.
Discussion
We review the grant of summary judgment de novo, construing the record in the light most favorable to Davric and resolving all reasonable inferences in its favor.
See Houlton Citizens’ Coalition v. Town of Houlton,
I. Federal Antitrust Claims
Davric alleges, first, that the defendants’ actions violated section one of the Sherman Antitrust Act, 15 U.S.C. § 1. In support of this claim, Davric targets three classes of behavior, which we address in turn.
A. The Scarborough “Boycott”
The heart of Davric’s claim is its contention that Rancourt, Faucher, and Ciаn-chette organized a boycott against Scarborough. The parties dispute whether such a boycott would be per se invalid or subject to rule of reason review,
see Northwest Wholesale Stationers v. Pacific Stationery & Printing Co.,
*147 The evidence regarding the MHHA boycott is presented almost entirely via the аffidavits submitted by Giuliano and several MHHA horsemen. Giuliano testified as follows: In early 1994, Faueher approached him and described various means whereby Faueher, Cianchette, and several partners planned to wrest control of Scarborough from Ricci. Faueher later informed Giuliano that Cianchette had connections with the MHHA. After what appears to have been a third conversation, during the summer оf 1994, Giuliano “understood that [Faueher] wanted the MHHA to be able to cut off its members from supplying horses [to Scarborough] without the risk that the-lack of horses could be made up through other horses which could have been brought ... by the [NEHHA]” (emphasis added).
The remaining evidence is derived from the horsemen’s affidavits: In late June or early July, 1996 — some two years after the conversations just described — several MHHA members noticed activity which suggestеd to them that certain MHHA leaders were trying to implement a boycott of Scarborough. Stanley Whittemore and Gary Mosher, two trainers with the MHHA, apparently asked various MHHA members to keep their horses out of Scarborough races. But the horsemen’s testimony regarding the boycott does not in any way suggest that anyone other than horsemen members of the MHHA was involved.
In light of the record evidence, there is no gеnuine issue of fact regarding a conspiracy among Davric’s competitors to withhold horses from Scarborough. Dav-ric can show only that Giuliano thought that Faueher would have liked to engineer a boycott in 1994 and that the MHHA tried to impose one on its own in 1996. Davric thus has provided insufficient evidence of a link between the defendants and the MHHA’s actions in 1996. “The mere existence of a scintilla of evidence in suрport of the plaintiffs position will be insufficient; there must be evidence on which the jury could reasonably find for the plaintiff.”

B. Defendants’ .Activities Before the Commission, the Legislature, and the Courts
Davric also alleges that the defendants’ efforts before the Commission, the Maine Legislature, and the courts are actionable under federal and state antitrust law. These endeavors, however, are protected by the
Noerr-Pennington
antitrust immunity doctrine. That doctrine, which derives from the First Amendment’s guarantee .of “the right ... to petition the government for redress of grievances,” U.S. Const, amend. I, shields from antitrust liability entities who join together to influence government action — even if they seek to restrain competition or to damage competitors.
See, e.g., United Mine Workers v. Pennington,
Davric seeks refuge in the
NoerrPennington
doctrine’s “sham” exception, which exempts a party’s resort to governmental process from antitrust immunity when such resort is objectively baseless and intended only to burden a rival with the governmental decision-making process itself.
See, e.g., City of Columbia v. Omni Outdoor Adven, Inc.,
In this case, it is apparent that the defendants sought to benefit from the
outcomes
of the processes at issue and that, in any case, they cannot be considered “objectively baseless.” First, the defendants’ efforts to lobby the Commission and the legislature were, in part, successful. They therefore cannot be considered shams, and are immune from federal or state antitrust scrutiny.

The litigatiоn arising out of Davric’s expulsion of the MHHA from Scarborough also satisfies the requirements for
Noerr-Pennington
immunity. “The existence of probable cause to institute legal proceedings precludes a finding that an antitrust defendant has engaged in sham litigation,” and such probable cause “requires no more than a reasonable belief that there is a chance that a claim may be held valid upon adjudication.”

*149 C. Defendants’ Attempts To Secure Foreclosure on Ricci’s Mortgage
Davric also argues that the defendants’ attempt to take advantagе of contacts with Ricci’s banker to effect a foreclosure on the Scarborough mortgage constituted an actionable violation of antitrust law. Like the district court, wé see inadequate evidence to support this contention.
To prevail with respect to this claim, Davric would have to demonstrate that it suffered antitrust injury as a result of the defendants’ attempt to have the mortgage foreсlosed.
See Brunswick Corp. v. Pueblo Bowl-O-Mat, Inc.,
II. Maine Antitrust Claims
Davric also claims that the defendants violated Maine’s antitrust laws.- See Me. Rev.Stat. Ann. tit. 10, § 1101 et seq. The Maine statute prohibits “[ejvery contract, combination ..., or conspiracy, in restraint of trade or commerce,” id. § 1101, and provides that “[wjhoever shall monopolize or attempt to monopolize or combine or conspire with any other person or persons to monopolize any рart of the trade or commerce of this State shall be guilty of a Glass C crime,” id. § 1102. 9
As described at length above, Davric cannot prevail on its conspiracy-based claims. Davric’s flawed arguments concerning the alleged boycott, the defendants’ attempts to interfere with Scarborough’s mortgage, and their efforts before the Commission, the Maine legislature, and the courts similarly doom any recovery under Mе.Rev.Stat. Ann. tit. 10, § 11Ó1. Moreover, Davric concedes that the defendants have not actually monopolized its market pursuant to § 1102. In fact, Davric’s brief strongly suggests that it remains the dominant player in the appropriate market:
Of the $18 million wagered on live racing in Maine in 1993, $10.8 million was wagered at Scarborough Downs. No other facilities offer the racing opportunities and purses available at Scarborough Downs. For decades’, Scarborough Downs had been the principal extended racing meet in the State of Maine and since the late 1980s it had been the only such facility in Central or Southern Maine.-
Further, as Davric notes, “a new track would first have to operate for two consecutive years in order to qualify for a share of the off-track betting ... revenue.”
The only remaining question, then, is whether Davric.can demonstrate that the defendants
attempted
to monopolize any particular mаrket. We have noted that the “Maine antitrust statutes parallel the Sherman Act,” and thus have analyzed claims thereunder according to the doctrines developed in relation to federal law.
Tri-State Rubbish, Inc. v. Waste Management, Inc.,
III. Tortious Interference Claims
Finally, Davric contends that a jury might have found that the defendants tortiously interfered with relations both between Davric and the horsemen and between Davric and administrative authorities. In Maine, “[interference with an advantageous relationship requires the existence of a valid contract or prospective economic advantage, interference with that contract or advantage through fraud or intimidation, and damages proximately caused by the interference.”
Barnes v. Zappia,
Davric’s assertion of tortious interference cannot survive summary judgment. Although Davric declares conelusorily that the defendants impeded its relationship with “horsemen and horsemen groups” аnd with the Commission, it nowhere explains specifically how the defendants’ conduct affected those relationships. It has produced no evidence of fraud or intimidation directed at either the MHHA or the Commission, and while it claims that the defendants attempted to intimidate NEHHA president Giuliano, it concedes that Giuliano refused to alter that organization’s relationship with Scarborough. This concession precludes the requisite showing of damages. All Davric has provided us with, then, is innuendo and conjecture. As noted above, we will not “accept the nonmovant’s subjective characterizations of events, unless the underlying events themselves are revealed.”

Conclusion
For the foregoing reasons, we AFFIRM.
Notes
. Two other individuals were named as defendants and granted summаry judgment, but Davric’s appeal as to these defendants has been dismissed with prejudice.
. The lower court excluded from its consideration much of the evidence regarding Faucher’s statements to Giuliano, on the ground that this evidence, which was presented via Giuliano's affidavit and deposition testimony, constituted hearsay. We think it is clear that a defendant’s own alleged statements to Giuli-ano were admissible agаinst that defendant; if made, they were classic admissions- and are excepted from the hearsay rule. To simplify this appeal, we will assume arguendo that each defendant’s statements were admissible against all of the defendants, though this is a much more debatable question.
. As discussed below, there is no evidence that any party ever attempted to implement a plan to secure foreclosure оf Scarborough’s mortgage.
. Giuliano’s affidavit does not state that Faucher told him that his confederates actually intended to employ such a stranglehold. Rather, the affidavit attests only to the inference Giuliano drew from- the conversation.
. Davric was granted racing dates, but as a condition, the Commission imposed restrictions on Ricci’s involvement with Scarborough's management.
. No evidence presentеd, however, links this "boycott” to any Scarborough competitor.
. Courts have differed as to whether the
Noeir-Pennington
doctrine is a creature of the First Amendment, in which case it would apply of its own force to state antitrust claims, or whether it instead constitutes a mere interpretation of the Sherman Act, in which case it would not necessarily apply to state antitrust statutes that failed to mirror their federal counterparts.
Compare Cheminor Drugs, Ltd. v. Ethyl Corp.,
. Davric's papers also allude to a separate suit in which Rancourl represented a creditor of Giuliano’s. It is unclear how litigation against Giuliano, who is not a party to this case, could ground an antitrust claim set forth by Davrie alone, but even if it could, this litigation is also protected by
Noerr-Penning-ton.
As Giuliano concedes, that suit resulted in a judgment against him. It thus does not matter whether, as Davrie suggests, Rancourt pursued the matter more vigorously than he otherwise might have due to animosity toward Giuliano.
Cf. City of Columbia,
. Despite the use of the word ''crime,” the Maine statute explicitly permits "any person” to seek redress for a violation. See Me.Rev. Stat. Ann. tit. 10, § 1104.
