Whitehead and Rocon appeal two orders issued by the district court on March 26, 2014. BP has filed motions to dismiss these appeals for lack of jurisdiction. As *258explained below, we grant both of BP’s motions to dismiss on identical grounds.

I.

Whitehead and Rocon are claimants in the court-supervised settlement program described in In re Deepwater Horizon, 732 F.3d 326, 329 (5th Cir. 2013). Both claimants received awards of compensation from the Claims Administrator. Both claimants’ awards were upheld by the settlement program’s Appeal Panel1 prior to October 2, 2013, when this court ordered a temporary injunction against processing certain claims under the settlement program.2 As a consequence of this court’s injunction, the claimants’ awards of compensation had not been paid as of March 2014,3 and apparently still have not yet been paid.

Seeking payment of their awards, Whitehead and Rocon both filed motions under the Federal Arbitration Act (“FAA”), codified at 9 U.S.C. § 9, styled as “Motion[s] to Confirm Arbitration Award and Order Payment.” The district court denied these motions in a pair of one-page orders on March 26, 2014.4 As the district court explained, “the ... injunction relating to BEL claims remains in place.... At such time as the mandate issues, the Claims Administrator will process BEL claims in accord with the decisions of the Fifth Circuit.”5 The district court did not address the merits of either motion or make any reference to the FAA.

Whitehead and Rocon appealed under 9 U.S.C. § 16, and continue to pursue their appeals even though the temporary injunction was dissolved on May 28, 2014.6 Neither Whitehead nor Rocon appear to have sought any further relief from the district court or the Claims Administrator. On August 1, 2014, BP filed motions to dismiss both appeals.

II.

This court’s appellate jurisdiction is a threshold question that may be addressed sua sponte or on motion.7 As the Supreme Court explained in Arthur Andersen LLP v. Carlisle, 556 U.S. 624, 628, 129 S.Ct. 1896, 173 L.Ed.2d 832 (2009) (internal quotation marks and citation omitted), jurisdiction over an appeal “must be determined by focusing upon the category of order appealed from, rather than upon the strength of the grounds for reversing the order.” In an appeal brought specifically under 9 U.S.C. § 16, the FAA’s provisions for appellate jurisdiction “unambiguously make[] the underlying merits irrelevant” even where the appellant’s arguments on the merits demonstrate “utter frivolousness.” 8

We therefore address only the jurisdictional question and take no position regarding the parties’ arguments on the *259merits. We express no opinion as to whether the settlement agreement includes an arbitration clause, whether the Claims Administrator’s awards of compensation constitute arbitral awards governed by the FAA, or whether BP is estopped from contesting either proposition.

In response to BP’s motions to dismiss, Whitehead and Rocon propose two possible grounds for this court’s appellate jurisdiction under the FAA. First, Whitehead and Rocon argue that the district court’s orders of March 26, 2014, constituted orders “denying confirmation of an award,” which are subject to appeal under 9 U.S.C. § 16(a)(1)(D). This argument must be rejected. As the Supreme Court explained in Hall St. Associates, L.L.C. v. Mattel, Inc., 552 U.S. 576, 582, 128 S.Ct. 1396, 170 L.Ed.2d 254 (2008), “[ujnder the terms of § 9, a court ‘must’ confirm an arbitration award ‘unless’ it is vacated, modified, or corrected ‘as prescribed’ in §§10 and 11.” It therefore follows logically that a district court’s order does not constitute an appealable order “denying confirmation” under 9 U.S.C. § 16(a)(1)(D) unless the order vacates, modifies, or corrects the arbitral award. This was precisely the reasoning applied in our recent decision in Murchison Capital Partners, L.P. v. Nuance Commc’ns, Inc., 760 F.3d 418 (5th Cir. 2014), in which we granted a motion to dismiss for lack of jurisdiction. In Murchison, 760 F.3d at 423, because “the district court neither confirmed nor vacated the arbitration award,” but instead remanded the case to the original arbitral tribunal “for further clarification,” we concluded that we lacked jurisdiction to hear the appeal under 9 U.S.C. § 16(a)(1)(D).9

A similar situation is presented in this case. The district court’s two orders neither mentioned the FAA nor purported to vacate, modify, or correct the Claims Administrator’s awards of compensation. Nor did the district court consider any of the enumerated grounds for declining to confirm an arbitral award under 9 U.S.C. § 10 or § 11. Nor did the district court indicate more generally that the motions filed by Whitehead and Rocon were denied with prejudice. On the contrary, the district court merely explained that it could provide no relief while this court’s temporary injunction in Deepwater Horizon, 732 F.3d at 345-46, remained in place. Therefore, because the district court’s orders neither confirmed nor denied confirmation of a purported arbitral award, we lack any basis for jurisdiction over these appeals under 9 U.S.C. § 16(a)(1)(D).

Second, Whitehead and Rocon argue that the district court’s orders of March 26, 2014, constituted “interlocutory order[s] ... continuing ... an injunction against an arbitration that is subject to this title” under 9 U.S.C. § 16(a)(2). This argument must also be rejected based on the terms of that provision, which have a “well-established meaning” illuminated by *260the case law analyzing the nearly identical language of 28 U.S.C. § 1292(a)(1).10 As the First,11 Second,12 Ninth,13 and Federal Circuits have all held, “an order that ‘continues’ an injunction ... is an order that extends the duration of the injunction that would otherwise have dissolved by its own terms.”14 But where an order does “not prolong, extend, or in any other way impact the duration of the ... injunction,” that order “cannot be characterized as ‘continuing’ the ... injunction” and therefore is not appealable.15

In the present case, the district court’s orders of March 26, 2014, did not prolong, extend, or in any other way impact the duration of the injunction ordered by this court on October 2, 2013, in Deepwater Horizon, 782 F.3d at 345-46. The district court’s orders simply explained the effects of that preexisting injunction. As we held in Frazar v. Hawkins, 376 F.3d 444, 447 (5th Cir. 2004) (quoting Ingram Towing Co., 59 F.3d 513, 516 (5th Cir. 1995)), an order that merely “enforces or interprets a previous injunction” does not give rise to interlocutory appellate jurisdiction under 28 U.S.C. § 1292(a)(1). Neither Whitehead nor Roeon identify any reason that the result should be different under the nearly identical language of 9 U.S.C. § 16(a)(2).

Accordingly, interpreting the terms of the FAA’s jurisdictional provisions in light of their well-established meaning,16 we conclude that the district court’s orders did not “continu[e]” any injunction within the meaning of 9 U.S.C. § 16(a)(2). We therefore have no interlocutory jurisdiction over these appeals.

III.

For the reasons set forth above, we lack jurisdiction under either 9 U.S.C. § 16(a)(1)(D) or § 16(a)(2). We therefore grant BP’s motions to DISMISS these appeals in their entirety.

DISMISSED.
