OPINION
Defendant-appellant HL Operating Corporation (“Hartmann”) appeals from the district court’s order denying its motion to compel arbitration on the basis that it waived its right to enforce an arbitration clause against plaintiffs-appellees Johnson Associates Corporation (“Johnson”) and T. Chantal International Limited (“T. Chantal”) in their suit for breach of contract and unjust enrichment. We affirm.
I.
This case involves a dispute over Hartmann’s contract with Johnson and T. Chantal to manufacture Hartmann’s luggage lines. Plaintiffs filed suit against Hartmann on December 22, 2009, seeking damages for breach of contract based on a “Sourcing Agreement” between the parties and claiming that Hartmann was unjustly enriched. Hartmann filed an answer and asserted a counterclaim for breach of contract. A case management conference was held. Thereafter, the parties engaged in a judicial settlement conference, held settlement discussions, and exchanged multiple offers from approximately the middle of April 2010 through the middle of June 2010 with the assistance of a magistrate judge. These efforts were unsuccessful. On July 1, 2010, the magistrate judge assisting with the settlement proceedings returned the case file to the magistrate judge otherwise handling the case because “it now appears that there is very little chance of resolution at this stage in the proceedings.”
That same day, Hartmann filed a motion to continue the trial and to modify the case management order, which at the time required the parties to complete written discovery and fact witness depositions by August 15, 2010. The district court denied Hartmann’s motion. Hartmann then served plaintiffs with interrogatories, requests for production of documents, and a request for admissions on July 2, 2010, and July 16, 2010; and plaintiffs served Hartmann with their discovery requests on July 18, 2010. On July 21, 2010, Hartmann noticed eight depositions; those depositions, however, were later postponed. The parties then filed a joint motion to modify the case management order to make the responses to the discovery requests due on August 26, 2010, and the court entered an order to that effect on August 12, 2010.
On August 23, 2010, just three days before the newly agreed-upon discovery deadline, Hartmann notified plaintiffs that it intended to exercise its right to arbitrate the dispute as provided by paragraph 13(a) of the Sourcing Agreement. Hartmann requested a response by August 24, 2010, and notified plaintiffs that in the event they did not agree to arbitrate, Hartmann would file a motion to compel arbitration. Hartmann also stated that “[i]t is our position that no discovery should be had until the Court rules on such a motion. Consequently, we will grant you an indefinite extension to respond to any of our outstanding discovery.... We ask that you do the same for Hartmann.” When plaintiffs failed to respond, Hartmann filed a motion to compel arbitration on August 25, 2010.
*716 On August 26, 2010, plaintiffs served their discovery responses on Hartmann in accordance with the deadline. They produced 1,151 pages of responsive documents and provided a 4.11 gigabyte hard drive containing responsive information. Plaintiffs then continued to seek discovery from Hartmann while the motion to compel arbitration was pending. On September 1, 2010, plaintiffs’ counsel wrote to Hartmann’s counsel: “Regardless of its motion to dismiss or stay the litigation pending arbitration, which Plaintiffs oppose, Hartmann is still required to comply with outstanding court orders regarding discovery, .... Specifically, Plaintiffs intend to continue to take depositions in this matter.” As a result, when Hartmann served written discovery responses and documents on September 15, 2010, it stipulated that “it [wa]s doing so under objection and Hartmann does not agree that its response to these requests constitutes any waiver of its right to arbitrate this dispute.”
The district court held a hearing on Hartmann’s motion to dismiss or compel arbitration in mid-November. In an opinion dated November 30, 2010, the court held that Hartmann had waived its right to compel arbitration because Hartmann “moved for and was granted an extension of time within which to file an Answer”; “asserted ten affirmative defenses and a counterclaim”; “engaged in a judicial settlement conference and informal efforts to resolve the case”; “both unilaterally and jointly with Plaintiffs moved for adjustments of the Case Management Order”; “served ... discovery requests”; and prejudiced Plaintiffs because “[w]hile litigating in this court for most of a year, Plaintiffs have participated in scheduling, requested discovery materials and prepared discovery responses” that “[they assert] ... will not be fully transferrable to an arbitration process.” Hartmann timely appeals.

III.
Hartmann makes two arguments on appeal. First, Hartmann contends that it could not have waived its right to arbitration because the Sourcing Agreement contains an explicit no-waiver provision: “No waiver by either party of any provision of this Agreement or of any breach or default shall constitute a continuing waiver of such provision or of any other provisions of this Agreement.” Because Hartmann raised this issue in its reply to its motion to compel arbitration below, and the district court failed to address it, Hartmann claims that the district court’s ruling must be vacated and the matter remanded for further consideration. Plaintiffs, on the other hand, assert that Hartmann did not properly raise the issue in its reply below, and that even if it did, the fact that the district court failed to address the argument does not mean that the court committed any error in making its determination that Hartmann waived its right to arbitration. We consider each of these arguments in turn.
Plaintiffs argue that Hartmann made only a “vague” reference in passing in its reply brief, without explanation or legal citation, that it could not waive the specific arbitration provision as a result of the general no-waiver provision in the Sourcing Agreement. This vague reference, they contend, was insufficient to raise the issue before the district court and thus did not preserve it for appeal. We disagree. Because the issue of waiver was first *717 raised in plaintiffs’ response, Hartmann’s reply was the first and only opportunity it had to address the issue. Moreover, although Hartmann’s argument lacked legal citation, it was not vague or made merely in passing. Hartmann argued that:
In addition to the facts that Plaintiffs have not and will not suffer any prejudice and that Hartmann has not taken any actions “completely inconsistent” with arbitration, Hartmann cannot be found to have waived its right because the parties expressly agreed that neither party could waive any provision of the Contract between them. Section 13(e) of the agreement between the parties states plainly that “[n]o waiver by either party of any provision of this Agreement or any breach or default shall constitute continuing waiver of such provision or of any other provisions of this Agreement.” Docket No. 1-1 at § 13(e). As such, not only did Plaintiffs expressly agree to arbitrate this dispute, but they also agreed that the actions they now claim constitute waiver would not in fact act as a waiver of the arbitration provision.
This was sufficient to preserve the issue for our review.
However, even though the no-waiver clause argument is preserved, Hartmann wrongly concludes that the district court’s failure to address the issue requires remand. “[T]he presence of [a] ‘no waiver’ clause does not alter the ordinary analysis undertaken to determine if a party has waived its right to arbitration.”

Second, Hartmann argues that the district court erred in concluding that Hartmann waived its right to arbitration based on its participation in the litigation. Although it has long been settled that a party can waive its contractual right to arbitration,
see Am. Locomotive Co. v. Gyro Process Co.,
In this case, the parties’ arguments focus on our unpublished decision in
Manasher v. NECC Telecom,
Regardless of whether a defendant is required to raise arbitration as a defense under Rule 8(c), a defendant’s failure to raise arbitration as an affirmative defense shows his intent to litigate rather than arbitrate. The filing of an answer is, after all, the main opportunity for a defendant to give notice of potentially dispositive issues to the plaintiff; and the intent to invoke an arbitration provision is just such an issue. Indeed, as a practical matter, an enforceable contractual right to compel arbitration operates as a quasi-jurisdictional bar to a plaintiffs claims, providing grounds for dismissal of the suit. It is therefore unsurprising that defendants routinely raise the right to arbitration in their answer, whether it is technically required by Rule 8 or not.
See Tenneco Resins, Inc. v. Davy Int’l, AG,
Hartmann is, of course, correct that the litigation in
Manasher
was more significant than the litigation in this case. In
Manasher,
the suit proceeded for over a year before the issue of arbitration was raised, and, during that time, there was a motion to certify the class and a motion to amend the complaint. Here, in contrast, the case had progressed only eight months before Hartmann raised its right to arbitration, and the parties’ prior motions addressed only settlement, scheduling deadlines, and discovery requests. But the fact that this case involved less litigation than in
Manasher
is not dispositive. And, in our view, Hartmann’s actions were also completely inconsistent with any rebanee on its right to arbitrate because Hartmann: failed to raise arbitration in its answer,
see Manasher,
Hartmann’s citations to decisions from other jurisdictions do not convince us otherwise.
J. & S. Constr. Co., Inc. v. Travelers Indem. Co.,
We are also unpersuaded by Hartmann’s assertion that it did not act completely inconsistently with any reliance on its right to arbitration because failing to assert arbitration as an affirmative defense, participating in only a “minimal” amount of litigation while mostly attempting to settle the case, and filing an answer and counterclaim are individually insufficient to support such a finding. Although Hartmann cites some authority in support of these assertions,
see Walker v. J.C. Bradford & Co.,
This leaves the second part of the waiver inquiry: prejudice. “Prejudice can be substantive, such as when a party loses a motion on the merits and then attempts, in effect, to relitigate the issue by invoking arbitration, or it can be found when a party too long postpones his invocation of his contractual right to arbitration, and thereby causes his adversary to incur unnecessary delay or expense.”
Kramer v. Hammond,
Hartmann argues that the district court erred by relying on the “time and resources” spent in litigation to conclude that plaintiffs were prejudiced by Hartmann’s delayed assertion of its right to arbitration. As support for this argument, Hartmann cites our statement that “delay alone, regardless of its length is not enough [to establish prejudice],”
Ziegler v. Aukerman,
Hartmann resists this conclusion, pointing to the Fifth Circuit’s statement in
Tenneco Resins
that “when only a minimal amount of discovery has been conducted, which may also be useful for the purpose of arbitration, the court should not ordinarily infer waiver based upon prejudice to the [opposing party].”
Hartmann also intimates that it cannot be responsible for plaintiffs’ discovery expenses because the metadata on the hard drive provided by plaintiffs shows that the information was saved on August 24, 2010, one day after Hartmann notified plaintiffs of its intent to arbitrate. But this does not benefit Hartmann either. If anything, the fact that the responsive information was saved to the disk only one day after Hartmann notified plaintiffs of its intent to arbitrate confirms that plaintiffs were prejudiced; after all, it is exceedingly unlikely that plaintiffs would have gathered all of that responsive material, or even a substantial portion of it, in the hours be *721 tween when it received notice of Hartmann’s intent to arbitrate on August 28, 2010, and its saving of the material to the disk on August 24, 2010. Because Hartmann’s actions were completely inconsistent with any reliance on its right to arbitration, and because Hartmann’s belated assertion of that right caused plaintiffs actual prejudice in the form of unnecessary delay and expense, we hold that Hartmann waived its right to arbitration.
IV.
For these reasons, we affirm the judgment of the district court.
Notes
. Hartmann has also taken at least one of these statements out of context. In
Fisher,
the Ninth Circuit’s full statement was:
"Absent a showing of prejudice
by the Fishers, the bare fact that Becker failed to raise an affirmative defense is inadequate by itself to support a claim of waiver of arbitration.
