OPINION OF THE COURT
JAMES HUNTER, III, Circuit Judge:In 1973, Congress enacted § 13(b) of the Federal Trade Commission Act, 15 U.S.C. § 53(b).1 The statute gives the Federal Trade Commission power to seek preliminary injunctions in the district court, pending the outcome of administrative cease and desist proceedings, in certain cases where there is reason to believe that a law, the enforcement of which has been delegated to the Commission, is being violated or is about to be violated. The district court in the present case enjoined appellants Aireo, Inc. and British Oxygen Company, Ltd., from engaging in a variety of activities, including disposing of any of Airco’s assets (except in the ordinary course of business) without prior approval of the Commission.
We vacate that portion of the injunction from which Aireo has appealed, as it applies to Aireo, and remand the matter to the district court for further proceedings.2
I
On February 26, 1974, the Federal Trade Commission (FTC) simultaneously commenced administrative proceedings and applied for a temporary restraining order and preliminary injunction against British Oxygen Company, Ltd., and three of its subsidiaries (BOC) and against Aireo. In substance the administrative complaint and application for injunction charged Aireo with violation of § 5 of the Federal Trade Commission *198Act, 15 U.S.C. § 45,3 and BOC with violations both of § 5 of the Federal Trade Commission Act and of § 7 of the Clayton Act, 15 U.S.C. § 18.4 The asserted violations arose from BOC’s acquisition, through public tender offer, of 35% of Airco’s common stock. In the Commission’s view, the acquisition was likely to lessen actual competition in the inhalation anesthetic equipment and inhalation therapy equipment markets and likely to lessen potential competition in the industrial gas market and in the medical pipeline market. Evidence of the asserted violations appeared in the July 25, 1975 agreement between BOC and Aireo. The parties agreed to exchange any confidential information, including technical data and know-how, necessary to evaluate the desirability of the proposed tender offer. As a result of this exchange of business data, Aireo in a December 10, 1973 memorandum consented to BOC’s proposed tender offer and to BOC’s representation on the Aireo board.
The Commission’s § 5 complaint against Aireo was based on Airco’s cooperation and facilitation of an allegedly illegal stock acquisition by BOC.
BOC is a large international corporation, the second largest world producer of industrial gas, an 8% holder of the domestic inhalation anesthetic equipment market and a significant European manufacturer and distributor of therapy equipment and medical pipeline systems. In two of these fields, inhalation therapy and inhalation anesthetic equipment, BOC or a subsidiary is an actual competitor of Aireo. In the other markets, the Commission characterized BOC as a potential entrant. BOC is allegedly one of the few corporations with sufficient financial resources to enter the United States industrial gas or medical pipeline markets despite significant domestic concentration and high entry barriers.
Appellant Aireo is a highly diversified corporation. It is the second largest domestic industrial gas producer with a 17% market share, and therefore, a potential competitor of any BOC venture in the United States industrial gas market. Prior to the tender offer, Aireo was the largest domestic producer in inhalation anesthetic equipment with a 35% market share and the second largest producer of inhalation therapy equipment with an 11% market share. Since BOC, through subsidiaries, had already entered into these domestic markets, Aireo and BOC were direct competitors. Aireo, in turn, had a 50% share of the domestic medical pipeline market, making it the leading firm in that market. BOC, with substantial European sales, was a potential entrant in the medical pipeline market.
Despite the fact that Aireo engaged in lines of commerce identical to those of BOC, Aireo alleges, and the FTC does not disagree, that only a portion of its assets are devoted to these endeavors. Sixty-four percent of Airco’s assets are devoted to lines of commerce which are not competitive, either actually or poten-tiallyj with those of BOC.5
On the basis of a probable anti-trust violation, the district court, after a hearing, issued a preliminary injunction under § 13(b) on March 8, 1974.6 BOC and Aireo were ordered to maintain Aireo as *199a separate entity, to refrain from confidential communications, to refrain from influencing Airco’s independent judgment, and in all ways to hold separate the two companies.
For purposes of this appeal, our focus is directed solely on the application to Aireo of Paragraph B of the injunction,7 which ordered both BOC and Aireo to:
B. Preserve and protect all assets of Aireo and refrain from disposing of or encumbering sueh assets except in the ordinary course of business, and refrain from commingling with any other assets of BOC or its subsidiaries, without prior approval of the Commission. (Emphasis added.)
The Commission, by a later order of the district court, was ordered to approve or disapprove any proposed disposition of assets by Aireo within fifteen days.
II
§ 13(b) requires that the Commission show the district court that it has “reason to believe” a violation has occurred or will occur and that, upon “weighing the equities and considering the Commission’s likelihood of ultimate success,” a preliminary injunction is “in the public interest.”
The fundamental dispute between the parties concerns the scope of activities which can be enjoined if the required showing is made. The Commission’s position has been that in an acquisition case, an injunctive provision like Paragraph B can be justified by a showing that the Commission would otherwise be unable to secure complete relief via a subsequent divestiture order. Aireo, on the other hand, argues that § 13(b) can only be invoked to prohibit actions which are themselves violative of a statute enforced by the Commission. We find it unnecessary to resolve this dispute, since in our opinion Paragraph B cannot be justified on the record here under either view.
Ill
We first consider Airco’s allegation that the district court’s fact findings do not satisfy Rule 52(a), Fed.R.Civ.P., which provides that:
in granting or refusing interlocutory injunctions, the court shall similarly set forth the findings of fact and conclusions of law which constitute the grounds of its action.
The district court’s findings were so limited as to be inadequate under Rule 52(a). Only one of the district court’s *200four limited factual findings makes any reference to Aireo. In that finding, the district court states:
3. That the Commission has made a “proper showing” of a “likelihood of ultimate success” under § 13(b) of the Federal Trade Commission Act that BOC’s acquisition of Airco’s stock may be found to be in violation of Section 7 of the Clayton Act and Section 5 of the Federal Trade Commission Act, at the conclusion of its administrative proceedings now pending before it. (Appendix at 195-196.)
We deem the lone finding insufficient to support the broad injunction issued against appellant Aireo under either theory of the scope of § 13(b). Finding of fact number three does not connect Air-eo with any violation of the antitrust laws, nor does it demonstrate a need for all of Airco’s assets to be preserved to guarantee that the Commission would be able to achieve whatever relief it may be shown to be entitled to. Secondly, there is no means for the reviewing court to determine what evidence served as the basis for the injunction. For this reason alone, a remand would be appropriate. O’Neill v. United States, 411 F.2d 139 (3d Cir. 1969); Fehringer v. Bluebeard’s Castle, 395 F.2d 851 (3d Cir. 1968).8
IV
But our concern with the proceedings in the district court goes beyond the failure to present adequate findings of fact. While it is not the proper role of this court to make findings of fact in the first instance, we have reviewed the record.
Our examination raises serious doubts as to whether there was sufficient evidence from which findings justifying the relief granted could have been made. Since these doubts persist even under the more expansive reading of § 13(b) urged by the Commission, we once again emphasize that we do not decide the statutory interpretation question.
V
For the foregoing reasons, Paragraph B of the injunction against appellant Aireo will be vacated and the case will be remanded to the district court for further proceedings consistent with this opinion.
. 15 U.S.C. § 53(b)
(b) Whenever the Commission has reason to believe—
(1) that any person, partnership or corporation is violating or is about to violate, any provision of law enforced by the Federal Trade Commission, and
(2) that the enjoining thereof pending the issuance of a complaint by the Commission and until such complaint is dismissed by the Commission or set aside by the court on review, or until the order of the Commission made thereon has become final, would be in the interest of the public—
the Commission by any of its attorneys designated by it for such purpose may bring suit in a district court of the United States to enjoin any such act or practice. Upon a proper showing that, weighing the equities and considering the Commission’s likelihood of ultimate success, such action would be in the public interest, and after notice to the defendant, a temporary restraining order or a preliminary injunction may be granted without bond
. Appellant Aireo has expressly limited its attack on the injunction to Paragraph B. Before the panel hearing of this case, counsel for appellant BOC informed the court and all counsel by letter that BOC “do[es] not intend to file a brief or otherwise prosecute this appeal.”
. § 5(a)(1) of the Federal Trade Commission Act, 15 U.S.C. § 45(a)(1) provides:
(a)(1) Unfair methods of competition in commerce, and unfair or deceptive acts of practices in commerce, are declared unlawful.
. § 7 of the Clayton Act, 15 U.S.C. § 18, in relevant part prohibits a corporation engaged in interstate commerce from acquiring “any part of the [stock] or assets of another corporation engaged also in commerce, where in any line of commerce in any section of the country, the effect of such acquisition may be substantially to lessen competition, or to tend to create a monopoly.”
. Airco’s other divisions include the following: Cryogenic Division, Alloys Division, Speer Carbon-Graphite-Division, Speer Electronics Division, Temescal Division, Vacuum Metals Division and Viking Division (Appellant’s Brief at 11).
. The district court preliminarily enjoined BOC and its subsidiaries, Aireo and all directors, employees, agents, successors of the two companies to:
*199A. Maintain Aireo as a viable separate and independent company and to make no changes in its operations likely to hinder a future divestiture of Aireo, including a merger, consolidation or acquisition of any equity interest.
B. Preserve and protect all assets of Air-eo and refrain from disposing of or encumbering such assets, except in the ordinary course of business, and refrain from commingling them with any other assets of BOC or its subsidiaries, without prior approval of the Commission.
C. Refrain from taking any steps to implement any provision of the agreements between Aireo and BOC, dated July 25, 1973, and December 10, 1973, respectively, except for Paragraph 4 of the December 10th agreement.
D. Refrain from making available or communicating to each other any confidential or proprietary information, including customer lists, trade secrets, fórmulas, know-how or manufacturing processes of each party, except this injunction shall not prohibit Aireo and BOC from operating under any license agreements between them which were outstanding prior to July 1, 1973 or prohibit them from engaging in normal sales and purchase activities with each other in a volume not in excess of that which existed prior to July 1, 1973.
E. Retain separate and unencumbered all shares of Aireo which BOC may own, acquire or control.
F. Refrain from attempting to influence or interfere with Airco’s independent judgment on any matter so as adversely to effect [sic] the competitive position of Aireo vis-a-vis BOC or any of its subsidiaries.
G. Refrain from transferring any shares of stock or other securities of Aireo from BOC Financial to BOC or any other entity or person unless such transferee shall subject itself to the jurisdiction of this Court.
. See footnote 2, supra.
. Aireo further alleges that the district court’s fact findings are verbatim copies of those prepared by the Federal Trade Commission. In view of our determination that the findings are, at any rate, inadequate under 52(a), we find it unnecessary to discuss this contention.
