that it has a substantial likelihood of prevailing on the merits; (2) that it will suffer irreparable injury if the injunction is denied; (3) that the threatened injury to the movant outweighs the injury that the opposing party will suffer under the injunction; and (4) that the injunction would not be adverse to the public interest. See Country Kids ‘N City Slicks, Inc. v. Sheen, 77 F.3d 1280, 1283 (10th Cir.1996). Because “a preliminary injunction is an extraordinary remedy, the right to relief must be clear and unequivocal.” SCFC ILC, Inc. v. Visa USA, Inc., 936 F.2d 1096, 1098 (10th Cir.1991) (citation omitted).
III. ULBA’s Likelihood of Success on the Merits
ULBA contends that despite our deferential standard of review, it has demonstrated a substantial likelihood of prevailing on the merits, because the district court made an error of law and “misapplied” the test set forth in Central Hudson Gas & Electric Corp. v. Public Service Comm’n of New York, 447 U.S. 557, 100 S.Ct. 2343, 65 L.Ed.2d 341 (1980). As a consequence, ULBA maintains that it has satisfied the first requirement for preliminary injunctive relief.
Under Central Hudson, laws restricting commercial speech are subject to an “intermediate” level of scrutiny. The Supreme Court stated:
In commercial speech cases, then, a four-part analysis has developed. At the outset, we must determine whether the expression is protected by the First Amendment. For commercial speech to come within that provision, it at least must concern lawful activity and not be misleading. Next, we ask whether the asserted government interest is substantial. If both inquiries yield positive answers, we must determine whether the regulation directly advances the governmental interest asserted, and whether it is not more extensive than is necessary to serve that interest.
Id. at 566, 100 S.Ct. 2343. In order to determine whether the district court made an error of law when it concluded that ULBA had not established a likelihood of success on the merits, we must review that court’s application of the Central Hudson test.
A. The District Court’s Central Hudson Analysis
The district court considered the four part Central Hudson test in detail in its Memorandum Decision Addressing Plaintiffs’ Motion For Summary Judgment, which it incorporated by reference into its Memorandum Decision Addressing Plaintiffs’ Motion For Preliminary Injunction.
With respect to the first part of the Central Hudson test, whether the regulated speech concerns lawful activity and is not misleading, the district court agreed with ULBA that a number of the challenged statutes regulated lawful, nonmis-leading speech. It rejected Utah’s argument that the majority of the statutes regulated conduct, not speech, and were thus constitutional. The court stated that, because “[c]onsumption of alcoholic beverages involves lawful conduct,” and “[c]om-mercial speech about lawful conduct is subject to First Amendment protection,” Utah could not “escape review of its legislation by asserting that the challenged conduct is unlawful under the very same legislation being reviewed.” Aplt’s App. at 268.
In the second part of the test, which requires the court to assess the substantiality of the government’s interest, the district court found that the interests cited by Utah in support of its advertising restrictions were in fact substantial. The court identified these interests as the “operation of a public business, with the goal of satisfying public demand for alcoholic
