2 Opinion of the Court 23-12095

Appeal from the United States District Court
for the Southern District of Florida
D.C. Docket No. 1:19-cv-23113-RNS
____________________

Before WILLIAM PRYOR, Chief Judge, JORDAN and MARCUS, Circuit
Judges.
WILLIAM PRYOR, Chief Judge:
This appeal requires us to decide issues related to personal
jurisdiction, foreign sovereign immunity, and the merits of a com-
plaint for breach of contract. Isaac Industries contracted with
Bariven, S.A., a Venezuelan oil company, for the sale of chemicals.
After Isaac shipped the products, Bariven failed to pay for them.
Later, Petroquímica de Venezuela, S.A., another oil company, as-
sumed Bariven’s debt and negotiated an extended payment period.
When that company made only the first payment, Isaac sued both
companies in the district court. The oil companies initially raised
objections about service of process and sovereign immunity. A
magistrate judge concluded that effective service occurred but rec-
ommended denying Isaac’s motion for default and ordering it to
amend its complaint. The oil companies raised no objection and
answered the amended complaint. When Isaac later moved for
summary judgment, the oil companies hired new counsel, argued
that no valid contracts exist and that sovereign immunity shields
Pequiven from suit, and urged the district court to defer ruling. The
district court granted summary judgment for Isaac. No reversible
error occurred. We affirm.

23-12095 Opinion of the Court 3

I. BACKGROUND

Two interwoven plots—Isaac’s sale of chemicals to the Ven-
ezuelan oil companies and the political upheaval in Venezuela—
set the stage for this appeal, so we begin with them. We then turn
to the procedural history of the lawsuit.
A. Isaac Industries Sells Chemicals to Bariven
But Never Receives Full Payment.
This action involves four entities, one American company
and three Venezuelan companies. Isaac Industries is a Florida cor-
poration engaged in the wholesale distribution of chemicals. Its
owner, David Avan, runs the company from Miami. Petroleos de
Venezuela, S.A., Petroquímica de Venezuela, S.A., and Bariven, S.A.
are oil and chemical companies associated with or owned by the
Bolivarian Republic of Venezuela. Petroleos de Venezuela, known
as PDVSA, serves as Venezuela’s state-owned and controlled oil
company. Bariven, a “wholly owned subsidiary of . . . PDVSA,” ac-
quires the equipment and machinery used to ﬁnd and extract oil.
And Petroquímica de Venezuela, known as Pequiven, operates as a
“petrochemical company engaged in the production and sale of ”
products like “fertilizers, industrial chemical products, oleﬁns, and
plastic resins.”
According to Avan, Isaac contracted with Bariven for the sale
and delivery of 2-Ethylhexanol in 2014. Under the contract, Bariven
would order the quantity it required at a unit price of $2,975.00 per
metric ton. Isaac would then ship the product to Vopak Terminal
in Puerto Cabello, Venezuela. Between July and September 2014,
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 4 of 25

4 Opinion of the Court 23-12095

Bariven placed three orders for a total of 5,993.873 metric tons of
2-Ethylhexanol.
After it shipped each order, Isaac provided Bariven with an
invoice. The ﬁrst two invoices, both dated July 6, 2014, charged
Bariven $5,950,000.00 for one shipment and $5,941,928.83 for the
other. The third invoice, dated September 19, 2014, charged
Bariven $5,939,843.35. All three listed Bariven and PDVSA as the
buyers and Pequiven as the consignee. Although Bariven never ob-
jected to the invoices, it never paid for the shipments.
After two years passed without payment from Bariven, rep-
resentatives of Pequiven asked Avan to meet about the “the current
status” of the debt. Avan agreed. Negotiations took place on Sep-
tember 21, 2016, in Miami. Saul Silva, Pequiven’s legal counsel, rep-
resented the oil company. During the negotiations, Avan discussed
the “monies owed to Isaac by Bariven . . . at length.” By the meet-
ing’s end, “Pequiven . . . voluntarily undertook the obligation to
make the payments” Bariven owed.
A written contract memorialized the agreement. Silva
signed on Pequiven’s behalf. The contract began with a reference
to a prior “payment contract with subrogation of debt signed be-
tween Bariven[,] S.A., PDVSA Services B.V., Pequiven, and ISAAC
INDUSTRIES INC.” It then described the terms of the newest re-
payment plan: that Pequiven agreed to pay the outstanding balance
in exchange for Isaac’s release of Bariven’s debt. The payment
structure applied an annual interest rate to the $17,831,772.18 prin-
cipal amount. And Pequiven promised to pay 15 percent of the
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 5 of 25

23-12095 Opinion of the Court 5

debt, plus interest, by December 31, 2016, followed by six quarterly
installment payments. In turn, Isaac’s release of Bariven’s debt re-
quired Pequiven’s full payment. Absent that payment, Bariven re-
mained responsible for the outstanding balance.
Pequiven met the ﬁrst deadline but no others. Consistent
with the written agreement, it tendered a payment of
$2,947,542.00 (15 percent of the debt plus interest) on December
30, 2016. Neither Pequiven nor Bariven tendered the six remaining
installments.
Two years later, the corporate governance of the oil compa-
nies splintered when Nicolás Maduro declared himself the winner
of Venezuela’s presidential election. In protest, Venezuela’s Na-
tional Assembly declared Maduro’s regime illegitimate and recog-
nized Juan Gerardo Guaidó Márquez, the president of the National
Assembly, as interim president in January 2019. The United States
immediately affirmed the 2015 National Assembly as the legitimate
government. But Maduro refused to cede control and blocked
Guaidó from power.

State-owned entities—like the oil companies—were caught
in the middle of the dueling regimes. In 2019, the National Assem-
bly granted Interim President Guaidó the power to appoint ad-hoc
boards to govern state entities. Interim President Guaidó, in turn,
appointed an ad-hoc board to govern PDVSA—a board that also
“safeguard[s] Bariven’s interests” abroad—and an ad-hoc board to
govern Pequiven.
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 6 of 25

6 Opinion of the Court 23-12095

Maduro refused to recognize these ad-hoc boards. His re-
gime occupied the oil companies’ Venezuelan offices. And it de-
clared the ad-hoc board members “criminals” for their “usurping
[of] public functions.” Today, the members of the ad-hoc boards
“reside outside [of] Venezuela” and risk “arrest” if they return. The
United States, for its part, continues to recognize the 2015 National
Assembly “as the last remaining democratic institution in Vene-
zuela.”

B. Isaac Sues the Oil Companies
for Breach of Contract.
Isaac sued Pequiven, Bariven, and PDVSA for breach of con-
tract in July 2019. Although filing the complaint proved easy, ef-
fecting service on the oil companies was another matter. Within a
month of filing the lawsuit, Isaac hired an international process ser-
vice to “effectuate service . . . under the Hague [Service] Conven-
tion.” On September 10, 2019, the process server confirmed that
Venezuela’s Central Authority received the process documents. Si-
lence followed. The Central Authority never confirmed that it ex-
ecuted service to the oil companies or certified receipt of service,
as required by the Hague Service Convention. See Convention on
the Service Abroad of Judicial and Extrajudicial Documents in Civil
or Commercial Matters arts. 2–6, opened for signature Nov. 15, 1965,
20 U.S.T. 361, 362–63.

The battle over service escalated near the one-year anniver-
sary of the action. Citing its “unsuccessful” attempts to serve the
defendants by the Central Authority, Isaac moved to permit
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 7 of 25

23-12095 Opinion of the Court 7

alternate service. After the district court granted the motion, the
oil companies began to participate in the litigation in earnest.

Each oil company moved to dismiss the action on two rele-
vant bases. First, each company argued that it qualified as an “in-
strumentality of a foreign state” under the Foreign Sovereign Im-
munities Act, which made alternative service improper. Second,
each company maintained that the district court lacked authority
to hear the suit because Isaac’s “[c]omplaint [was] completely de-
void of any allegations” that the companies fell “within one of the
[Sovereign Immunities Act’s] enumerated exceptions to immun-
ity.” The district court granted the motions to dismiss “based [on]
insufficiency of service of process,” gave Isaac additional time to
complete service, and affirmed the oil companies’ ability to “reas-
sert the remaining bases for dismissal.”

After more time passed with no response from Venezuela’s
Central Authority, Isaac cited Article 15 of the Hague Service Con-
vention and moved for an entry of default against the oil companies
under Federal Rule of Civil Procedure 55(a). Article 15 permits a
judge to enter a default judgment “even if no certificate of service
or delivery has been received” so long as a plaintiff “transmitted”
the service documents “by one of the methods” described in the
Convention, “six months . . . has elapsed,” and “no certificate of
any kind has been received, even though every reasonable effort
has been made to obtain it.” Hague Service Convention, supra, 20
U.S.T. at 364. Isaac argued that its attempt to serve process satisfied
each of the three conditions: it effectuated service under the
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 8 of 25

8 Opinion of the Court 23-12095

Convention; nearly two years had passed; and the Central Author-
ity “ha[d] refused to return the required certificate of service.”

In a report and recommendation, the magistrate judge
agreed that Isaac met “all three requirements” of Article 15. Nev-
ertheless, the magistrate judge recommended that the district court
“exercise its discretion” to deny Isaac’s “request for a default” be-
cause the oil companies appeared early in the case, contested ser-
vice of process, and filed meritorious motions to dismiss. The mag-
istrate judge gave the parties 14 days to file written objections to its
report and recommendation and cautioned that “[f]ailure to file ob-
jections . . . shall bar the parties from attacking on appeal unob-
jected-to factual and legal conclusions contained in this [r]eport.”
Despite this warning, the oil companies filed no objections.

The district court adopted the report and recommendation.
It denied Isaac’s motion for entry of a default, dismissed the com-
plaint without prejudice, and ordered Isaac to file an amended
complaint that “properly assert[ed]” that the oil companies satisfied
an exception to immunity under the Sovereign Immunities Act. It
also prohibited the oil companies from “re-asserting a challenge to
service of process.”

In compliance with that order, Isaac ﬁled an amended com-
plaint. This time, it alleged that the companies satisﬁed the com-
mercial-activity exception to immunity under the Act. In response,
only PDVSA moved to dismiss based on sovereign immunity, and
the district court later dismissed the claims against that entity.
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 9 of 25

23-12095 Opinion of the Court 9

Pequiven, in contrast, responded that Isaac failed to “allege that
Pequiven received any consideration for its purported assumption
of debt.” Both Pequiven’s and Bariven’s answers to the amended
complaint stated that the allegations about the commercial-activity
exception required no response because they called for a “legal con-
clusion.” And neither oil company challenged service of process.

After Isaac served various discovery requests, the oil compa-
nies admitted little and provided nothing in response. The presi-
dents of Pequiven’s and PDVSA’s ad-hoc boards filed affidavits that
attested that the oil companies could not “identify any individual[s]
competent to testify” as their corporate representatives. Nor did
they “have possession, custody or control of documents” relevant
to the proceedings because the Maduro regime maintained “com-
plete possession and control of all such information” and occupied
their Venezuelan offices. These facts made any effort to “collect
information” for production impossible.

When Isaac eventually moved for summary judgment, the
oil companies rolled out new counsel, new legal positions, and new
evidence. They filed a declaration from Jesus Bellorin, the new ad-
ministrator of Pequiven, and a copy of Pequiven’s bylaws—both
submitted after the close of discovery. Pequiven sought to use that
new evidence to resurrect its sovereign-immunity argument. It ar-
gued that the bylaws established that Silva, Pequiven’s purported
general counsel, lacked authority to negotiate and sign the contract
on its behalf. And it asserted that the contract with Isaac was invalid
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 10 of 25

10 Opinion of the Court 23-12095

for lack of consideration. Without an official “act” or valid contract,
Pequiven argued that Isaac could not establish the commercial-ac-
tivity exception to sovereign immunity. As for Bariven, the oil
companies invoked the Florida statute of frauds to argue that Isaac
failed to prove that a valid contract existed.

The oil companies also asked the district court to “deny or
defer consideration” of Isaac’s motion for summary judgment un-
der Federal Rule of Civil Procedure 56(d). With the “minimal” “dis-
covery record,” the oil companies contended that the “interests of
justice . . . require[d] postponement.” In their view, Isaac’s motion
asked the district court to rule in its favor “without ever allowing
Defendants to identify evidence in its own records to support a full
defense.”

Isaac moved to strike Bellorin’s declaration and Pequiven’s
bylaws under Federal Rules of Civil Procedure 26 and 37. It argued
that the new evidence amounted to “sandbagging” because
Pequiven “hadn’t pled lack of authority as an affirmative defense
and had answered a request for admission by stating it was ‘with-
out knowledge’ regarding Silva’s authority.” The parties also filed
a pretrial stipulation which stated for the first time that Bariven was
not an agency or instrumentality of Venezuela.

The district court granted Isaac’s motion for summary judg-
ment for breach of contract. The district court ruled that Pequiven
implicitly waived sovereign immunity when it failed to assert it in
its answer and that, in any event, Isaac satisfied the commercial-
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 11 of 25

23-12095 Opinion of the Court 11

activity exception. It also chastised Pequiven for complaining about
Isaac’s thin factual record when it had failed to produce “contrary
evidence” of its own. The district court ruled that the bylaws “were
[not] properly before” it. Then it concluded that, even if they were,
the bylaws would not change the outcome because they author-
ized “the delegation of authority . . . to allow for others,” like Silva,
“to execute contracts.” And the district court then ruled that the
undisputed material facts established that Pequiven and Bariven
breached their contracts with Isaac.

The district court also refused to delay or defer its ruling un-
der Rule 56(d). It explained that the oil companies “declined to de-
pose Isaac’s witness or otherwise proactively participate in the dis-
covery process.” They also failed to “identify a single piece of doc-
umentary or testimonial evidence that they believe might actually
controvert Isaac’s showing or help their case.”

The final judgment assessed the damages owed by the oil
companies. The total balance owed by Pequiven—inclusive of the
principal plus interest—amounted to $23,384,373.00. The total bal-
ance owed by Bariven amounted to $15,111,440.00, plus interest.
The district court held the oil companies jointly and severally liable
for the principal amount of $15,111,440.00. Bariven owed prejudg-
ment interest of $307,155.66 plus postjudgment interest. And
Pequiven owed the additional amount of $8,272,933.00 plus
postjudgment interest.

II. STANDARDS OF REVIEW

Two standards govern our review. We review de novo ques-
tions of law about service of process. See Prewitt Enters. v. OPEC, 353
F.3d 916, 920 (11th Cir. 2003). We review de novo whether a defend-
ant enjoys immunity under the Sovereign Immunities Act. R&R
Int’l Consulting LLC v. Banco do Brasil, S.A., 981 F.3d 1239, 1243 (11th
Cir. 2020). And we review de novo a summary judgment. See Tillis
ex rel. Wuenschel v. Brown, 12 F.4th 1291, 1296 (11th Cir. 2021). We
draw all reasonable inferences for the oil companies and view the
evidence in the light most favorable to them. Black v. Wigington,
811 F.3d 1259, 1265 (11th Cir. 2016). We review the denial of a mo-
tion under Rule 56(d) for abuse of discretion. Burns v. Town of Palm
Beach, 999 F.3d 1317, 1330 (11th Cir. 2021).

III. DISCUSSION

We divide our discussion in five parts. First, we explain that
the oil companies waived their challenge to personal jurisdiction
when they failed to object to the magistrate judge’s report and rec-
ommendation and then omitted any reference to insufficient ser-
vice of process in their answers to the amended complaint. Second,
we explain that Pequiven waived sovereign immunity when it
failed to raise sovereign immunity in either its answer or its motion
to dismiss the amended complaint. Third, we explain that the rec-
ord presents no genuine issue of fact that Pequiven breached its
contract with Isaac. Fourth, we explain that the record also pre-
sents no genuine issue that Bariven too breached its contract.
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 13 of 25

23-12095 Opinion of the Court 13

Finally, we explain that the district court did not abuse its discretion
when it denied the oil companies’ motion under Rule 56(d).

A. The Oil Companies Waived Their Challenge
to Personal Jurisdiction.
The oil companies contend that, without proper service, the
judgment against them is void for lack of personal jurisdiction.
Isaac responds that the oil companies waived their challenge when
they failed to object to the magistrate judge’s final report and rec-
ommendation. We agree that the oil companies waived their chal-
lenge.

Settled rules govern our inquiry. Under our precedent, a
party who fails “to file objections to a magistrate judge’s order in a
non-dispositive matter to the district court waives that claim on ap-
peal.” A.L. ex rel. D.L. v. Walt Disney Parks & Resorts U.S., Inc., 50
F.4th 1097, 1112 (11th Cir. 2022). Our rules reinforce this conclu-
sion. See 11TH CIR. R. 3-1 (“A party failing to object to a magistrate
judge’s findings or recommendations . . . waives the right to chal-
lenge on appeal the district court’s order based on unobjected-to
factual and legal conclusions if the party was informed of the time
period for objecting and the consequences on appeal for failing to
object.”). And we have long warned defendants that they “waive[]
any objection to the district court’s jurisdiction over [their] per-
son[s]” when they fail to “object[] to it in a responsive pleading or
a [Rule] 12 motion.” Palmer v. Braun, 376 F.3d 1254, 1259 (11th Cir.
2004). So, if a defendant fails to challenge a “defect in personal ju-
risdiction” in his answer to the operating complaint, he “consent[s]
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 14 of 25

14 Opinion of the Court 23-12095

to the court’s jurisdiction.” Pardazi v. Cullman Med. Ctr., 896 F.2d
1313, 1317 (11th Cir. 1990). And once he “consent[s] to litigate the
action in [our] court, [we] may not . . . dismiss the suit for lack of
personal jurisdiction or insufficient service of process.” Id.

Under these tenets of civil procedure, the oil companies
waived their objection to personal jurisdiction twice over. They
first waived the challenge when they failed to object to the magis-
trate judge’s report and recommendation on Isaac’s motion for an
entry of default under Rule 55(a). The report and recommendation
advised the oil companies that this failure would bar them “from
attacking on appeal . . . legal conclusions contained in this
[r]eport.” Despite this warning, the oil companies chose not to re-
spond. And the district court then adopted the report and recom-
mendation. This failure alone is enough to waive a challenge to
insufficient service of process. See Walt Disney Parks, 50 F.4th at
1112. And the oil companies’ second waiver, which occurred when
they later filed answers to the amended complaint that omitted any
reference to service of process, reinforces our conclusion that they
abandoned this challenge and “consented” to the exercise of juris-
diction over them. Pardazi, 896 F.2d at 1317.

The oil companies’ counterarguments fail to convince us
otherwise. They first contend that “it is unclear as to what [they]
could have even objected” because the magistrate judge held “that
service had not been effected under the Hague [Service] Conven-
tion.” This argument misleads through half-truth. To be sure, the
magistrate judge concluded that Isaac never perfected service
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 15 of 25

23-12095 Opinion of the Court 15

under the Convention. But the magistrate judge also concluded
that Isaac satisfied its obligations under the Convention because it
met the three conditions for a default judgment under Article 15.

The oil companies could have raised several objections to
the magistrate judge’s recommendation—including the same ones
they raise here. They could have argued that Isaac did not satisfy
the three conditions of Article 15. They could have argued that the
Sovereign Immunities Act required Isaac to attempt service
through alternative methods. And they could have objected to the
magistrate judge’s recommended prohibition on additional chal-
lenges to service of process. But they chose not to press these argu-
ments, and we refuse to entertain them now.

The oil companies next argue that even if they waived this
challenge, we should still review it for “plain error . . . in the inter-
ests of justice.” We decline their invitation. The oil companies
made a strategic choice when they declined to object to the report
and recommendation or to object to personal jurisdiction in their
answers. Instead of risking that Isaac would next move for, and per-
haps obtain, a default judgment, the oil companies chose to defend
the action on the merits. No “interest of justice” obliges us to con-
sider their waived challenge to personal jurisdiction now that they
lost on the merits of the claims for breach of contract.

B. Pequiven Waived Its Sovereign-Immunity Challenge.
Pequiven argues that the Sovereign Immunities Act shields
it from this suit on two fronts. First, it asserts that it did not waive
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 16 of 25

16 Opinion of the Court 23-12095

its sovereign-immunity challenge. Second, it argues that the com-
mercial-activity exception to sovereign immunity does not apply.
Because we decide its appeal on the first front, we do not reach the
second.

The Sovereign Immunities Act provides the “sole basis for
obtaining jurisdiction over a foreign state.” Argentine Republic v.
Amerada Hess Shipping Corp., 488 U.S. 428, 434 (1989). Under the
Act, we presume that a foreign state, along with its “agenc[ies]” and
“instrumentalit[ies],” is immune from suit in federal courts. 28
U.S.C. §§ 1603–04. But this presumption falls away when one of the
Sovereign Immunities Act’s “specified exception[s]” applies. Saudi
Arabia v. Nelson, 507 U.S. 349, 355 (1993).

This appeal turns on the waiver exception, which provides
that a federal court can hear an action “in which the foreign state
has waived its immunity either explicitly or by implication.” 28
U.S.C. § 1605(a)(1). “Under the law of the United States, a waiver
of immunity”—either explicit or implicit—“may not be with-
drawn, except by consent of all parties to whom (or for whose ben-
efit or protection) the waiver was made.” RESTATEMENT (THIRD)
OF FOREIGN RELATIONS LAW § 456(3) (AM. L. INST. 1987). So “sover-
eign immunity, once waived, cannot be reasserted.” Aquamar S.A.
v. Del Monte Fresh Produce N.A., Inc., 179 F.3d 1279, 1287 n.18 (11th
Cir. 1999). Our Court, wary of this harsh consequence and “loath
to broaden the scope of the implied waiver provision,” construes
the exception “narrowly.” Id. at 1291 n.24 (citation and internal
quotation marks omitted). But even so, an agency or
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 17 of 25

23-12095 Opinion of the Court 17

instrumentality of a foreign state “reveals its intent to waive its im-
munity” when it (1) “agree[s] to arbitration in another country,”
(2) “agree[s] that the law of a particular country should govern a
contract,” or (3) “file[s] a responsive pleading in an action without
raising the defense of sovereign immunity.” Calzadilla v. Banco La-
tino Internacional, 413 F.3d 1285, 1287 (11th Cir. 2005).

Pequiven lands squarely within the implied-waiver excep-
tion: it filed a “responsive pleading” to Isaac’s amended complaint
“without raising the defense of sovereign immunity.” Id. This
omission establishes a “clear and unambiguous” intent to waive the
defense. Aquamar, 179 F.3d at 1292 (citation and internal quotation
marks omitted). To be sure, Pequiven moved to dismiss the original
complaint based on sovereign immunity. But Isaac cured its earlier
omission of allegations about an exception to sovereign immunity
when it alleged in its amended complaint that the commercial-activ-
ity exception applied to Pequiven. In response, the oil companies’
joint motion to dismiss reasserted a sovereign-immunity defense
only for PDVSA. That motion mentioned Pequiven—but argued
that the complaint “fail[ed] to state a claim” against the entity be-
cause it did not allege that Pequiven “received any consideration
for the assumption of debt.” Pequiven’s answer similarly omitted
any assertion that sovereign immunity shielded the company. In-
stead, it asserted two affirmative defenses: one about the political
crisis in Venezuela and one about lack of consideration. Sovereign
immunity went unmentioned until Pequiven’s new counsel sought
to resurrect it in response to the motion for summary judgment.

18 Opinion of the Court 23-12095

This litigation conduct established Pequiven’s intent to
“waive[] its immunity . . . by implication.” 28 U.S.C. § 1605(a)(1).
After raising a sovereign-immunity challenge in the first round,
Pequiven dropped all sovereign-immunity arguments in the sec-
ond. Unlike PDVSA, it did not move to dismiss the amended com-
plaint on sovereign-immunity grounds. Its answer failed to contest
the amended complaint’s allegations about the commercial-activ-
ity exception. It did not seek discovery. And it decided to take part
in the litigation for over a year without even a hint (that is, until
new counsel appeared) that sovereign immunity shielded it from
federal jurisdiction. Pequiven may regret this course of action, but
it must live with the consequences of its litigation tactics.

Pequiven unpersuasively argues that it “asserted the defense
throughout the litigation,” starting with its original motion to dis-
miss. But in that motion, Pequiven’s single grievance focused only
on Isaac’s failure to present any allegation that Pequiven satisfied
any of the sovereign-immunity exceptions. After Isaac amended its
complaint, Pequiven had the opportunity to contest the new alle-
gations about the commercial-activity exception but failed to do so.

Pequiven also erroneously relies on an agreed order that
granted Pequiven’s motion to dismiss and affirmed its “ability to
reassert the remaining bases for dismissal contained” in its motion
“once service of process [was] effectuated.” Pequiven casts that or-
der as one that “preserv[ed] all of [its] defenses.” But the text of the
order, which preserved Pequiven’s ability to “reassert” its sover-
eign-immunity defense, betrays Pequiven’s description. The order

23-12095 Opinion of the Court 19

did not preserve in perpetuity a general assertion of sovereign im-
munity. Instead, it required action that Pequiven declined to take.

Pequiven’s remaining argument relies on two out-of-circuit
precedents, neither of which support its position. In Drexel Burnham
Lambert Group Inc. v. Committee of Receivers for Galadari, the Second
Circuit declined to find an implicit waiver where the defendant did
not plead the immunity defense in its answer but followed that
pleading “almost immediately” with a “motion to dismiss that did.”
12 F.3d 317, 326 (2d Cir. 1993). And in Canadian Overseas Ores Ltd.
v. Compania de Acero del Pacifico S.A., the Second Circuit refused to
find an implicit waiver where the defendant never filed an answer,
but still asserted the defense of sovereign immunity in a petition
for removal, a memorandum in opposition to remand, a stipulation
concerning the amended complaint, and a motion to dismiss the
amended complaint. 727 F.2d 274, 276–78 (2d Cir. 1984). Unlike the
defendants in Drexel and Canadian Overseas, Pequiven did not assert
sovereign immunity in either its answer or its motion to dismiss the
amended complaint. This omission, in the context of the proce-
dural history before us, establishes a “clear and unambiguous” in-
tent to waive the defense. See Aquamar, 179 F.3d at 1292 (citation
and internal quotation marks omitted).

Pequiven also maintains that sovereign immunity is not an
affirmative defense, and it argues that the burden-shifting frame-
work we have long applied to these issues has been “undermined
. . . by recent Supreme Court precedent.” At oral argument,
Pequiven added that the Supreme Court’s recent grant of certiorari
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 20 of 25

20 Opinion of the Court 23-12095

in Republic of Hungary v. Simon directly presents the question of
which party bears the burden of proof on sovereign immunity. 144
S. Ct. 2680 (2024) (mem.).

The resolution of that issue has no effect on this appeal.
Even if a plaintiff bears the ultimate burden of proof on sovereign
immunity, a defendant must, at least, raise it in a motion to dismiss
or contest a complaint’s allegations that an exception applies to
avoid waiver “by implication.” 28 U.S.C. § 1605(a)(1). That is, the
burden of proof comes into play only if a defendant contests that
the plaintiff has satisfied its burden by pleading and proof. And
Pequiven offered no contest by motion, answer, or proof. The clos-
est Pequiven came was a belated declaration and equivocal bylaws
offered at summary judgment, both of which were too little, too
late. So we leave the burden-of-proof arguments for an appeal that
actually presents the issue.

C. Summary Judgment for Isaac Industries
Was Proper as to Pequiven.
Pequiven contends that the district court erred when it
granted summary judgment to Isaac on its claim for breach of con-
tract. Pequiven argues that Saul Silva lacked authority to bind it,
and, in any event, the contract “was not supported by considera-
tion.” But Pequiven waived the lack-of-authority defense when it
failed to assert it in its answer, and its argument about considera-
tion fails on the merits.
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 21 of 25

23-12095 Opinion of the Court 21

Whether an agent possesses authority to bind its principal is
an affirmative defense that must be pleaded. See 5 CHARLES ALAN
WRIGHT & ARTHUR R. MILLER, FEDERAL PRACTICE AND PROCEDURE
§ 1271 (4th ed. 2024). “Failure to plead an affirmative defense gen-
erally results in a waiver.” Latimer v. Roaring Toyz, Inc., 601 F.3d
1224, 1239 (11th Cir. 2010). And when a defendant raises an affirm-
ative defense in, for example, a motion for summary judgment, we
have ruled that its “failure to specifically plead the defense in its
answer or amended answer” bars a challenge on appeal. See Easter-
wood v. CSX Transp., Inc., 933 F.2d 1548, 1551 (11th Cir. 1991).

Pequiven first asserted a lack-of-authority defense in its re-
sponse to the motion for summary judgment, so it waived the de-
fense in the process. We decline to consider it now.

Waiver aside, Pequiven’s lack-of-authority argument fails
on the merits. In GDG Acquisitions LLC v. Government of Belize, we
declined to decide whether Belize’s purported agent possessed “ac-
tual authority” to enter an agreement because Belize “subse-
quently ratified his actions and, therefore, agreed to be bound by
them” when it made payments in line with the agreement. 849 F.3d
1299, 1308–10 (11th Cir. 2017). That logic applies with equal force
here. Even if we assume that Silva lacked actual or apparent au-
thority, Pequiven ratified the agreement months later when it met
the first payment deadline and tendered a payment of $2,947,542.00
to Isaac.

22 Opinion of the Court 23-12095

Pequiven’s argument about lack of consideration also fails.
“In a bilateral contract, the exchange of promises by both parties
constitutes consideration” whenever “each party must promise to
do something which will yield a benefit or advantage to the other,
or which will result in a detriment or disadvantage to himself in
exchange for the other promise.” Johnson Enters. of Jacksonville, Inc.
v. FPL Grp., Inc., 162 F.3d 1290, 1311 (11th Cir. 1998) (citation omit-
ted). A promise, “no matter how slight,” will “constitute sufficient
consideration so long as a party agrees to do something that [it is]
not bound to do.” Thompkins v. Lil’ Joe Records, Inc., 476 F.3d 1294,
1304 n.12 (11th Cir. 2007) (citation and internal quotation marks
omitted). Isaac gave up its ability to file “any claim” against
Pequiven, which, in exchange for its assumption of the debt, re-
ceived an extended period for payment. This exchange of promises
supplied consideration for the contract.

Pequiven responds that the district court erred when it
found that “Pequiven is Bariven’s parent company.” The district
court relied on that finding to conclude that Isaac’s “release [of]
Bariven from its payment obligations” qualified as a benefit, in part,
because of the “very close economic ties between parent and sub.”
Pequiven maintains that PDVSA, not Pequiven, was Bariven’s par-
ent company. And Pequiven relies on its nonparental status to as-
sert that it could not have received a benefit because, until it en-
tered the contract, it had no “repayment period to extend and
[Isaac] had no claims against Pequiven to release.”
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 23 of 25

23-12095 Opinion of the Court 23

We reject these arguments. Pequiven clearly had some rela-
tionship to Bariven and some role in the original transaction: each
invoice listed Pequiven as a consignee. In addition, the agreement
between Pequiven and Isaac referenced another “payment contract
with subrogation of debt signed between Bariven[,] S.A., PDVSA
Services B.V., Pequiven, and ISAAC INDUSTRIES INC.” Pequiven
had some obligation and received a benefit from the extended
deadline. To be sure, as the district court explained, “this evidence
might wither in the face of a rigorous cross examination, or the
production of contrary evidence, [but] that is not the procedural
posture of this case.” Without evidence of its own, Pequiven can-
not create a material dispute of fact about consideration through
conjecture.

D. Summary Judgment for Isaac Industries
Was Proper as to Bariven.
Bariven, for its part, argues that Isaac’s “failure to adduce a
signed written contract as required under Florida’s statute of frauds
prevented [Isaac] from proving the existence of an enforceable con-
tract as to Bariven.” Isaac responds that the district court correctly
held that the contract was valid because it dealt with “goods which
have been received and accepted.” Under the statute of frauds, “a
contract for the sale of goods for the price of $500 or more is not
enforceable . . . unless there is some writing sufficient to indicate
that a contract for sale has been made between the parties and
signed by the party against whom enforcement is sought.” FLA.
STAT. § 672.201(1) (2024). But the statute exempts contracts “[w]ith
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 24 of 25

24 Opinion of the Court 23-12095

respect to goods . . . which have been received and accepted.” Id.
§ 672.201(3)(c).

The exemption applies here. The district court concluded
that the unsigned invoices—along with Avan’s testimony, the
email initiating negotiations over the unpaid debt, the written
terms of Pequiven and Isaac’s agreement, and the partial payment
from Pequiven—supported the “find[ing] that Bariven agreed to
purchase the chemicals, that it received and accepted the ship-
ments, and that it failed to pay for them.” We agree.

Bariven’s attempts to conjure up disputed issues of material
fact fail. It complains that the emails and contract between Isaac
and Pequiven do not “reflect Bariven’s assent to a contract.” But
Bariven does not dispute that the unrebutted evidence established
that it received and accepted the 2-Ethylhexanol. It also faults the
district court for “relying on the partial payment from Bariven’s
parent” when Bariven was a wholly owned subsidiary of PDVSA,
not Pequiven. But, as discussed above, that error does not merit
reversal or undermine the judgment in favor of Isaac.

E. The District Court Did Not Abuse Its Discretion When
It Denied the Oil Companies’ Rule 56(d) Motion.
The oil companies argue that the district court abused its
discretion when it refused to deny or defer ruling on Isaac’s mo-
tion, under Rule 56(d), “until such time that the crisis [in Vene-
zuela] and its effect on [the oil companies’] access to discovery were
resolved.” The district court did nothing of the sort. A party
USCA11 Case: 23-12095 Document: 52-1 Date Filed: 01/24/2025 Page: 25 of 25

23-12095 Opinion of the Court 25

seeking relief under Rule 56(d) must support its request with an af-
fidavit or declaration that “specifically demonstrate[s] how post-
ponement of a ruling on the motion will enable [it], by discovery
or other means, to rebut the movant’s showing of the absence of a
genuine issue of fact.” Burns, 999 F.3d at 1334 (citation and internal
quotation marks omitted). The oil companies failed to make this
showing. As the district court explained, they “declined to depose
Isaac’s witness or otherwise proactively participate in the discovery
process.” They also failed to “identify a single piece of documen-
tary or testimonial evidence that they believe might actually con-
trovert Isaac’s showing or help their case.” Because “vague asser-
tions that additional discovery will produce needed, but unspeci-
fied facts” do not satisfy Rule 56(d), id. (citation and internal quota-
tion marks omitted), the district court did not abuse its discretion
when it declined to defer or delay granting summary judgment.

IV. CONCLUSION

We AFFIRM the judgments in favor of Isaac.
