This antitrust case, which requires us to clarify what sort of evidence a plaintiff must adduce to make out a trialworthy claim for a vertical restraint of trade, presents a question of first impression in this circuit. We turn to this question mindful that vertical restraints have “provoked more reconsideration of established rules, or more disagreement between courts and commentators” than most other areas of antitrust law. Herbert Hovenkamp, Federal Antitrust Policy: The Law of Competition and Its Practice § 11.1, at 441 (2d ed.1999).
I
We begin with the cast of characters. Plaintiff-appellant Euromodas, Inc. is a corporation engaged in the retail sale of men’s clothing. Defendant-appellee Club-man, Inc. is engaged in the same business. The two retailers are direct competitors in San Juan, Puerto Rico. Defendant-appellee Zanella, Ltd. is an Italian manufacturer of fíne men’s clothing. Until 1997, both Eu-romodas and Clubman sold Zanella trousers. What happened thereafter propelled the parties from the marketplace to the federal courthouse.
Euromodas alleges that Clubman, which operates a large number of stores in Puer-to Rico, used its market power to force *14 Zanella into a minimum resale price maintenance scheme. Euromodas claims that this scheme was in part intended to — and did — restrict its access to Zanella pants. Because this appeal arises in an unusual posture, see infra Part II, we defer further development of the background facts until we reach the merits of the antitrust claim.
For the nonce, it suffices to say that Euromodas, endeavoring to regain its competitive footing, sued both Clubman and Zanella in the federal district court. It alleged a violation of section 1 of the Sherman Act, 15 U.S.C. § 1. After pretrial discovery had been completed, all three parties moved for summary judgment. The district court granted the defendants’ motion and denied the plaintiffs cross-motion.
Euromodas, Inc. v. Zanella, Ltd.,
The district court’s decision comprised three discrete but interdependent rulings. Initially, the court determined that the plaintiff — Euromodas—had not complied with local procedural rules. Id. at 203-04. This determination shaped the court’s conception of which parts of the record could be considered on summary judgment. Viewing the case through that prism, the court ruled that the plaintiff had not adduced sufficient evidence of concerted action to fix prices and, thus, had failed to make out an antitrust violation. Id. at 205-06. Along the way, the court denied the plaintiffs cross-motion for summary judgment on the ground that it did not comply with the court’s local rules. Id. at 204 n. 5 (discussing D.P.R.R. 311.12).
This appeal followed. In it, the plaintiff (i) challenges the district court’s resolution of the procedural issue; (ii) assigns error to the court’s entry of summary judgment for the defendants; and (iii) protests the denial of its cross-motion for brevis disposition.
II
Our logical starting point is the procedural issue, for its resolution will determine what facts properly comprised the summary judgment record and, thus, what facts the lower court should have considered in deciding whether to grant summary judgment. This inquiry centers on D.P.R.R. 311.12.
1
The District of Puerto Rico promulgated that rule to aid in the task of identifying genuine issues of material fact that might affect the entry of summary judgment.
See, e.g., Ruiz Rivera v. Riley,
The local rule imposes bilateral obligations. It requires that a party who moves for summary judgment submit, in support of the motion, “a separate, short, and concise statement of the material facts as to which the moving party contends there is no genuine issue to be tried and the basis of such contention as to each material fact, properly supported by specific reference to the record.” D.P.R.R. 311.12. In turn, the rule requires a party opposing a summary judgment motion to include with its opposition a short and concise statement “of the material facts as to which it is contended that there exists a genuine issue to be tried,” with proper record citations. Id. The penalty for failure is potentially harsh; the facts delineated in the movant’s statement will be “deemed to be admitted unless controverted by the statement required to be served by the opposing party.” Id.
Rules such as Local Rule 311.12 were adopted pursuant to a suggestion of this court,
see Stepanischen v. Merchants Des-
*15
patch Transp. Corp.,
Zanella moved for summary judgment in full compliance with Local Rule 311.12 (Clubman joined Zanella’s motion and we need not discuss separately its quest for summary judgment). When the plaintiff served its opposition, it omitted a separate statement listing controverted material facts. The district court perceived this omission as a “blatant disregard” of Local Rule 311.12, proceeded to “deem as admitted the relevant uncontested facts submitted by Zanella with its motion for summary judgment,” and limited the summary judgment record to those facts.
Euromo-das,
The plaintiff asserts that this approach constituted error. It tells us that it complied with the imperatives of Local Rule 311.12 notwithstanding its failure to formulate a separate statement of controverted material facts. Therefore, its thesis runs, the district court, while entitled to deem the defendants’ assertions of fact admitted, also should have taken the facts identified in the plaintiffs opposition fully into account.
We conclude that the district court erred in its interpretation of the local rule. The court found Euromodas to have violated Local Rule 311.12 merely because it did not include a separate statement of disputed facts with its opposition. But Local Rule 311.12, as written, does not always require that a party opposing summary judgment put forth its version of the facts in a separate statement. The rule requires only that the nonmovant identify any facts in the movant’s statement with which it takes issue. See D.P.R.R. 311.12. In other words, an opposing party is required to file such a statement only if (and to the extent that) it wishes to register and preserve a potential dispute as to one or more of the facts advanced by the movant.
In this instance, Euromodas was content to accept the, facts proffered by the defendants, so the district court appropriately treated those facts as admitted. The plaintiff, however, regarded those facts as incomplete, and it desired to augment them with further facts — facts that it viewed as undisputed and which were neither inconsistent with nor contradictory to those contained in the movants’ Local Rule 311.12 statement. The local rule, as it existed at that time, did not require those additional facts to be presented in a particular form. 3 Because those additional facts were supported by the record, the *16 lower court should have considered them (while at the same time accepting the facts set forth in the movants’ Local Rule 311.12 statement). Its failure to do so constituted error.
Ill
This error does not necessarily require reversal. After all, we afford de novo review to orders granting or denying summary judgment.

Section 1 of the Sherman Act prohibits “[ejvery contract, combination ... or conspiracy, in restraint of trade or commerce.” 15 U.S.C. § 1. There are two prerequisites for a successful section 1 claim. First, there must be concerted action.
Monsanto Co. v. Spray-Rite Serv. Corp.,
In this instance, the plaintiffs case hinges on the interposition of what is alleged to be an illegal vertical restraint. A vertical restraint is a restraint of trade involving a combination of persons at different levels of the market structure.
See M & H Tire Co. v. Hoosier Racing Tire Corp.,
Vertical price-fixing agreements, however, are a special subset of vertical restraints. As such, they qualify for different treatment. A vertical price-fixing agreement that establishes a minimum price normally is regarded as a naked restraint of trade and, thus, as illegal per se.
See Business Elecs. Corp.,
Here, the district court concluded that the plaintiff had not adduced enough evidence to sustain a viable section 1 claim under either theory.
Euromodas,
In sifting the evidence, we must array it in the light most hospitable to the party opposing summary judgment (here, the plaintiff), indulging all reasonable inferences in that party’s favor.

Houlton Citizens’ Coalition,
In addition to these familiar principles, a special constraint applies in vertical restraint cases. Antitrust liability is strong medicine (for example, it exposes a defendant to treble damages,
see
15 U.S.C. § 15), and thus section 1 of the Sherman Act has been authoritatively interpreted to limit the inferences that may be drawn from ambiguous evidence.
Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475
U.S. 574, 588,
To create a trialworthy issue in a vertical restraint case brought pursuant to section 1 of the Sherman Act, a plaintiff must make two showings: concerted action and harm to the competitive process. See id. at 12. The plaintiff cannot make either of these showings here.
We need not go beyond the first prong of this two-part test. To satisfy that requirement, there “must be evidence that tends to exclude the possibility of independent action by the manufacturer and distributor.”
Monsanto,

The basic premise of the plaintiffs complaint is that a manufacturer (Zanella) and a dealer (Clubman) conspired to maintain an artificially high retail price for Zanella pants; and that Clubman, to further this scheme, successfully pressured Zanella to stop selling goods to its price-cutting competitor (Euromodas). The question is whether these averments, on the facts of record and under the applicable legal standards, add up to a potential antitrust violation.
As a threshold matter, the plaintiff suggests that we should answer this question in the affirmative because the defendants failed to provide any evidence negating the possibility that they were acting in combination. Appellant’s Br. at 32. We reject this resupinate reasoning. In an antitrust case, the burden is on the accuser to make at least a prima facie showing of concerted action.
See Monsanto,
We start this phase of our inquiry by rehearsing the facts that were deemed admitted for purposes of summary judgment.
See Corrada Betances v. Sea-Land Serv., Inc.,
Zanella kept up a dialogue with Club-man during this period of abstinence. At a meeting in New York, held in September of 1997, Zanella informed the plaintiff that Clubman had agreed to create “Zanella corners” in its stores. Although Zanella expressed enthusiasm about this concept, pricing policies were not discussed. In or around April of 1998, however, Zanella told the plaintiff that it would no longer sell to it. Zanella gave no reason for this exclusionary decision. Clubman proceeded to resume the marketing of Zanella trousers and to inaugurate the “Zanella corners.”
To these facts we must add the augmentative evidence assembled by the plaintiff. In a deposition, Clubman’s chief executive officer (Germán Ramírez) testified that he had resolved not to handle Zanella pants in the future unless Zanella satisfactorily addressed his concerns about being undersold by the plaintiff. Ramirez discussed this resolve with Zanella’s president (Armando DiNatale) and received assurances that Zanella would “take care of’ the problem. Ramirez professed neither to know nor to care how Zanella intended to proceed or what action it purposed to take. *19 The plaintiff sees this as “smoking gun” testimony. It asks us to interpret Ramirez’s words as showing that Clubman was seeking to have Zanella cut off its (the plaintiffs) supply of Zanella trousers and terminate the preexisting distribution relationship.
The plaintiff also places substantial weight on the testimony of a Zanella vice-president (Thomas Cohan), which corroborates the fact that Clubman threatened to stop buying Zanella pants unless Zanella addressed Clubman’s concerns about the plaintiffs pricing practices. Cohan’s testimony does not, however, go anywhere near as far as the plaintiff suggests. We have scoured the deposition transcript and find no support for the plaintiffs brazen assertion that Cohan’s testimony “confirmed that Zanella and Clubman agreed that Eu-romodas be terminated in order to allow Clubman to maintain its preferred price of $265 [per pair of trousers].” Appellant’s Br. at 38.
The plaintiff also relies, to some extent, on DiNatale’s deposition testimony. Without question, that testimony shows that Zanella made no bones about its intention to halt trouser sales to the plaintiff. It also supports a clear inference that, when pressed, Zanella opted to do business with the larger retailer (Clubman) rather than to jeopardize that relationship by continuing to deal with the plaintiff. But DiNa-tale, like Cohan, made no mention of wanting to maintain a particular price or price level, and the deposition, taken as a whole, does not evince concerted action.
These facts leave room for many inferences, which — to the extent that they are reasonable — ordinarily would be taken in favor of the plaintiff.
See Podiatrist Ass’n,
So it is here. The record, read as favorably to the plaintiff as antitrust law and summary judgment practice permit, shows that Clubman complained bitterly to Za-nella about the plaintiffs low prices, and that Zanella reassured Clubman that it would, in some unarticulated manner, “take care of’ the situation (i.e., the price-cutting issue). There is nothing, however, that reflects a commitment on Zanella’s part to a minimum retail price maintenance scheme or that suggests that Zanel-la’s reassurances were anything more than an acknowledgment of its unilateral decision to stop supplying the plaintiff. The raw fact that a distributor’s actions are an attempt to pressure a manufacturer into terminating a distribution relationship with a price-cutting competitor is not enough either to show concerted action or to defeat summary judgment.
See Garment Dist.,
This case is not unique. Other courts consistently have held that the fact that a dealer was terminated in response to complaints from competing dealers is insufficient, without more, to survive a motion for summary judgment.
See, e.g., Winn v. Edna Hibel Corp.,
The plaintiff strives to deflect the force of this reasoning in two ways: (i) by seeking refuge in a pair of Eleventh Circuit cases, and (ii) by pointing to the fact that Zanella never advanced any alternative explanation for severing ties with the plaintiff. Neither foray succeeds.
The Eleventh Circuit’s decision in
Helicopter Support Systems, Inc. v. Hughes Helicopter, Inc.,
The plaintiffs reliance on
City of Tuscaloosa v. Harcros Chems., Inc.,
The plaintiffs second foray is no more rewarding. It is true that alternative explanations sometimes are cited as a basis for finding the existence of substantial evidence supporting a plausible and legitimate reason for the conduct of antitrust defendants.
See, e.g., Burlington Coat,
This is such a case. The most natural inference from the evidence — that the manufacturer took sides as between two dealers and chose the more lucrative of them — makes manifest a legitimate, independent reason for terminating the less desirable distribution relationship.
See Garment Dist.,
That ends this aspect of the matter. The plaintiff has charged price-fixing, impure and simple — and the utter absence of meaningful evidence of concerted action dooms the plaintiffs case.
C
Although we need go no further, we add a coda. Even were we to find significantly probative evidence of concerted action (which we do not), the fabric of the plaintiffs case reveals yet another flaw. For the sake of completeness, we mention this shortcoming.
An agreement to terminate a price-cutter to placate another dealer does not constitute a per se violation of section 1 of the Sherman Act.
See Business Elecs. Corp.,
There is no evidence here that the defendants ever agreed on either a minimum price or price level. Thus, the plaintiffs claim of per se illegality founders.
See Business Elecs. Corp.,
This leaves the rule of reason. In a vertical restraint case, liability under that approach requires a showing of harm to the competitive process.
See Interface Group, Inc. v. Mass. Port Auth.,
Here, the plaintiff has made no showing that the putative restraint had an adverse impact on the competitive process. Although it tendered evidence of its own losses, an injury to an individual competitor is not the legal equivalent of an injury to competition in the relevant market.
Id.
Without any evidence that the defendants’ actions were inimical to the competitive process, the plaintiff — who had the burden of proof on this point,
see Jefferson Parish Hosp. Dist. No. 2 v. Hyde,
IV
We summarize succinctly. 6 Although the district court took too narrow a glimpse of the summary judgment record, de novo review of the record as a whole persuades us that there is no genuine issue as to any material fact and that the defendants are entitled to judgment as a matter *22 of law. There is no rational view of the proffered facts that can support the imposition of antitrust liability.
Affirmed.
Notes
. The District of Puerto Rico revised, reorganized, and renumbered its compendium of local rules in September of 2003. Because tile summary judgment motions in this case were adjudicated prior thereto, we refer throughout to the earlier version.
. To be sure, the district court also denied the plaintiff's motion for summary judgment on the basis of the plaintiff's supposed noncompliance, qua movant, with the requirements of D.P.R.R. 311.12.
See Euromodas,
. The current iteration of this obligation, codified in Local Rule 56(c), is worded somewhat differently. We take no view as to what that language requires. See supra note 1.
. The fact that the plaintiff had cross-moved for summary judgment does not alter this methodology. In that circumstance, a reviewing court examines each motion independently, applying the principles articulated above. See Blackie v. State of Me., 75 F.3d 716, 721 (1st Cir.1996).
. It is abundantly clear that this special constraint — limiting inferences from ambiguous evidence — applies in vertical restraint cases.
See, e.g., Monsanto,
. Because we have upheld the entry of summary judgment for the defendants, it would be an empty exercise to probe the circumstances surrounding the denial of the plaintiff’s cross-motion for summary judgment. We caution, however, that we express no opinion on the district court’s reasoning in that regard.
