    KANNE, Circuit Judge. A federal jury found Christopher
    Beaver guilty of participating in a price-fixing conspiracy,
    
    15 U.S.C. § 1
    , and making false statements to a federal
    law enforcement agent who was investigating that con-
    spiracy, 
    18 U.S.C. § 1001
    (a)(1). Beaver challenges his
    convictions on appeal, arguing that the government
    failed to prove at trial that a price-fixing conspiracy
    existed, that he joined the conspiracy, or that he made
    false statements. We affirm.

    I. HISTORY
    In October 2003, Gary Matney, a manager at the India-
    napolis office of Prairie Material Ready-Mix Concrete,
    approached the Federal Bureau of Investigation to report
    the existence of a price-fixing conspiracy involving several
    of Prairie Material’s competitors. According to Matney,
    Prairie Material was being pressured to join the con-
    spiracy, a claim that led the FBI to investigate the pricing
    activities of five ready-made concrete producers in the
    Indianapolis metropolitan area: (1) Shelby Materials, Inc.;
    (2) Builder’s Concrete & Supply Co., Inc.; (3) Irving
    Materials, Inc.; (4) Hughey, Inc.; and (5) Ma-Ri-Al, which
    does business as Beaver Materials Corp. The investiga-
    tion reached a turning point on May 25, 2004, when FBI
    agents executed search warrants on the five companies,
    and interviewed the companies’ corporate officers and
    employees regarding the existence of the conspiracy.
    Information recovered at that time substantiated many
    of Matney’s claims, and set into motion a chain of events
    that would mark the demise of the price-fixing scheme.
    Shelby Materials’s Vice-President, Richard Haehl, im-
    mediately admitted his criminal conduct and offered to
    help the government investigate the cartel; the govern-
    ment, in turn, granted Haehl amnesty conditioned on his
    continued cooperation and, if required, truthful testimony
    at trial. Shortly thereafter, the government obtained
    indictments against Builder’s Concrete, Irving Materials,
    and Hughey, Inc., and their respective corporate officers,
    Gus “Butch” Nuckols, Price Irving, and Scott Hughey.
    Nuckols, Irving, and Hughey eventually admitted their
    roles in the conspiracy and entered into plea agreements,
    in which they, too, offered to help the government in-
    vestigate the cartel and testify truthfully at trial if called.
    Upon enlisting the cooperation of Haehl, Nuckols, Irving,
    and Hughey, the government sought an indictment
    No. 07-1381                                                  3
    against Beaver Materials and its corporate officers. The
    government’s efforts paid off in April 2006, when a federal
    grand jury returned a four-count indictment against
    Beaver Materials, Ricky Beaver—the company’s Com-
    mercial Sales Manager—and Christopher Beaver—the
    Operations Manager. Two of the counts were directed at
    Christopher. First, the indictment charged Christopher
    with participating in a price-fixing conspiracy in viola-
    tion of § 1 of the Sherman Antitrust Act. Specifically, the
    indictment alleged that he met with competitors at “a
    horse barn owned by Gus B. Nuckols, III a/k/a Butch
    Nuckols, president of Builder’s Concrete and Supply Co.,”
    at which they agreed to increase prices, limit discounts,
    and implement surcharges; carried out and enforced
    their agreement; and attempted to conceal the conspiracy.
    See 
    15 U.S.C. § 1
    . The indictment also charged Chris-
    topher with making false statements regarding his par-
    ticipation in the conspiracy to an FBI agent who investi-
    gated it. See 
    18 U.S.C. § 1001
    (a)(1). Unlike their alleged
    cohorts, Christopher, Ricky, and Beaver Materials es-
    chewed plea agreements and instead exercised their
    rights to a jury trial, at which the three were tried jointly.1
    The evidence introduced at trial, which we review in a
    light most favorable to the government, see United States
    v. Andreas, 
    216 F.3d 645
    , 670 (7th Cir. 2000), was as
    follows:
    1
    Beaver Materials was charged with one count of participating
    in the price-fixing conspiracy. Like Christopher Beaver, Ricky
    Beaver was charged with participating in the conspiracy and
    making false statements to the FBI. Also named in the in-
    dictment was John Blatzheim, Executive Vice-President of
    Builder’s Concrete. Blatzheim was likewise charged with
    participating in the conspiracy and making false statements
    to the FBI, but rather than go to trial he pled guilty to the
    charges.
    4                                               No. 07-1381
    The government presented the testimony of Haehl,
    Nuckols, Irving, and Hughey, who each provided details
    as to the origins of the price-fixing conspiracy and Christo-
    pher Beaver’s role within the scheme. The men explained
    that, at the turn of the century, the ready-made-concrete
    market in the Indianapolis area was extremely competi-
    tive. The market was primarily occupied by eight concrete
    producers that often vied for the same customers by
    bidding on their construction projects. The companies’
    bidding and pricing processes were largely uniform. At the
    beginning of construction season in the spring of each
    year, the producers would send price lists to potential
    clients to inform them of the lowest possible rates at
    which they could provide concrete. The price lists usually
    featured five dollar amounts that went into the calcula-
    tion of the quoted price. First, there was the base
    price—or, as it was called, the gross price—of the desired
    amount of a particular mix of concrete. Next, the price
    list provided the available discount off the gross price
    for promptly submitting payment; the price list then
    deducted this discount, which yielded the net price. But
    the producers’ net prices were identical more often than
    not, so to distinguish themselves and undercut their
    competition the producers would include a fourth dollar
    amount on the price list: an additional discount from
    the net price. The producers would then calculate and
    quote to potential clients the resulting discounted net
    price as the lowest price at which they could provide
    the concrete. But as the competition for customers
    grew over the years, the producers offered increasingly
    larger net-price discounts that, in turn, depressed the
    market value of concrete, and, consequently, reduced the
    producers’ overall profits.
    The four men each continued that, in July 2000, Nuckols
    decided that it was time to address the falling market
    value of concrete. He accordingly organized a meeting
    No. 07-1381                                                5
    at his horse barn in Fishers, Indiana, of corporate officers
    of area concrete producers so they could discuss methods
    of “getting the price up.” The meeting was attended by,
    among others, Haehl, Irving, Hughey, and Beaver Materi-
    als’s representative, Ricky Beaver. All those present
    discussed ways in which they could “stabilize the market,”
    leading someone (it is not exactly clear who) to propose
    a $5.50 limit on each producers’ gross-price discount for
    a cubic yard of concrete; the gross-price-discount limit, in
    turn, translated to a net-price-discount limit of $3.50
    per cubic yard. Although no vote was taken on the pro-
    posal, no one in attendance objected to it, nor did anyone
    refuse to impose the limit; as Haehl described it, “Nobody
    objected, nobody disagreed, nobody walked away.” Indeed,
    each witness testified that he left the meeting with the
    firm understanding that an agreement to limit net-price
    discounts had been reached.
    However, each of the four co-conspirators stated, the
    members of the concrete cartel did not always abide
    by their agreement. This periodic cheating contributed to
    the continuing downward spiral of concrete market
    prices, despite the cartel’s efforts. As a result, individual
    members of the cadre separately met with each other at
    various times and locations to shore up the plan. But when
    those meetings failed to raise the price of concrete,
    Nuckols and Hughey called a second meeting of the entire
    cartel in May 2002, this time at the Signature Inn in
    Fishers. Every company participating in the cartel was
    represented, and, again, Nuckols, Haehl, Irving, Hughey,
    and Ricky Beaver attended. The purpose of the meeting
    was, as Haehl described it, “to just reaffirm” the agree-
    ment to limit their net-price discounts at $3.50. Just like
    at the earlier meeting at Nuckols’s horse barn, no one
    objected to imposing the limit. Moreover, those in atten-
    dance all agreed to a method of enforcing the limit: if they
    became aware that another cartel member was offering a
    6                                             No. 07-1381
    net-price discount greater than $3.50, they would con-
    front that producer about his cheating. And based, in part,
    on this plan, the meeting at the Signature Inn ended with
    Haehl, Nuckols, Irving, and Hughey each believing the
    attendees had reaffirmed the discount limit.
    The four witnesses each continued to testify that in the
    days after the meeting at the Signature Inn, they at-
    tempted to enforce the net-price-discount limit by con-
    tacting those producers whom they believed were cheat-
    ing on the cartel agreement. In fact, each man stated
    that, at one time or another they either confronted some-
    one whom they believed was cheating, or were them-
    selves accused of cheating. Nevertheless, their efforts
    to police the scheme proved incapable of reversing the
    downward spiral of concrete prices; as Nuckols testified,
    in the days following the meeting “our prices just were
    not doing well and they were going in the gutter.” So
    Nuckols arranged another meeting at his horse barn in
    October 2003 to discuss the discount limits further.
    Haehl, Irving, and Hughey again attended, but this time
    Ricky Beaver did not; as it turned out, Ricky had not
    accurately conveyed the details of the agreement to the
    appropriate individuals at Beaver Materials. As Price
    and Hughey elaborated, Beaver Materials underbid
    Hughey, Inc., on two separate occasions after the July
    2000 meeting, causing Hughey to telephone Christopher
    Beaver directly and ask him if Beaver Materials was
    cheating. Christopher, according to Hughey, denied that
    was the case, and stated that “he was at the discount
    that was established in the agreement with everyone.”
    But, apparently, Ricky was confused about that discount,
    leading him to provide Christopher with the wrong infor-
    mation, and, in turn, causing Beaver Materials to quote
    prices in dereliction of the agreement. Therefore, to avoid
    the potential for any further confusion, Christopher took
    over representing Beaver Materials.
    No. 07-1381                                               7
    The four co-conspirators each further testified that
    the October 2003 began with Hughey bemoaning the fact
    that no one was abiding by the agreement, and urging
    those who did not want to follow the agreement to leave
    the meeting. Hughey recounted his exhortation: “ ‘You
    know, guys, this thing is not being adhered to. And we
    need to decide are we going to agree on this and do what
    we say we’re going to or just walk on out of here.’ ” But no
    one walked out. Instead, Hughey’s lecture spurred a
    discussion among all the attendees—including Christopher
    Beaver—during which they again reassured one another
    that they each would limit their discounts to $3.50 off of
    the net price. The discussion did not end there, however.
    The group also agreed to increase the net price of each
    cubic yard of performance-mix concrete by $2, and by $2.50
    for each cubic yard of bag-mix concrete. They further
    agreed to add a collective $2-per-cubic-yard surcharge for
    all concrete produced in the winter. Moreover, those
    present reasserted their commitment to police the agree-
    ment by confronting apparent cheaters.
    Just like at the two earlier meetings, Haehl, Nuckols,
    Irving, and Hughey each stated that they understood
    that the attendees at the October 2003 meeting agreed to
    limit their net-price discounts to $3.50, in addition to
    adopting additional pricing restraints. No one present at
    the meeting—Christopher Beaver included—objected to
    the net-price-discount limit. Even more, Hughey testified,
    Christopher volunteered to contact the manager at Ameri-
    can Concrete, another Indianapolis ready-made-concrete
    producer that was not represented at the meeting, “ ‘and
    get him the message on what we agreed on.’ ”
    After each of the four co-conspirators testified, the
    government presented the testimony of several FBI agents
    who recounted the agency’s investigation into the con-
    crete cartel. As relevant here, Special Agent Neil Free-
    8                                            No. 07-1381
    man testified that when the FBI conducted its searches
    and interviews on May 25, 2004, he questioned Christo-
    pher Beaver regarding the existence of the conspiracy;
    different FBI agents simultaneously interviewed Ricky
    Beaver and Allyn Beaver, Christopher’s father and com-
    pany President. During their conversation, Christopher
    stated that he had been employed by Beaver Materials
    for 21 years, and that in the “last couple years” he had
    become more involved in the pricing of the company’s
    products because he would soon be replacing his father
    as President. When Freeman asked Christopher if he
    had attended any meetings at Nuckols’s horse barn,
    Christopher answered, “No.” Christopher also stated
    that he did not know of any other employee of Beaver
    Materials having attended such a meeting. He further
    told Freeman that he saw Beaver Materials’s competitors
    only when attending meetings of the industry trade
    group, the Indiana Ready-Mix Association. In all, Freeman
    stated, Christopher “denied being involved with any
    kind of discussion of price fixing,” and further disavowed
    ever meeting with any of the competing producers to
    discuss pricing and discount agreements.
    The government rested its case after it presented the
    evidence regarding the origins of the price-fixing con-
    spiracy, Christopher Beaver’s participation, and his
    statements to Special Agent Freeman. Christopher then
    moved for a judgment of acquittal on the basis that the
    government had failed to introduce “any kind of evidence
    that would indicate that [Christopher] joined the con-
    spiracy.” See Fed. R. Crim. P. 29(a). After the district
    court denied the motion, Christopher presented the
    testimony of his sole witness—Chuck Mosely, who worked
    at Beaver Materials from 1991 until 2006 as a concrete
    salesman. Mosely testified that, during his time as a
    salesman, Christopher never told him how to price con-
    crete. However, Mosely also stated that he knew that
    No. 07-1381                                               9
    Christopher attended “a price fixing meeting at Butch
    Nuckols’s horse barn.”
    Beaver Materials, on the other hand, presented the
    testimony of Allyn Beaver and Charles Sheeks, Beaver
    Materials’s corporate counsel. Allyn testified that Christo-
    pher Beaver had some influence over the company’s
    prices, including the authority to authorize certain dis-
    counts. Allyn also stated that he was unaware of any price-
    fixing agreement between Beaver Materials and
    its competitors, though he did know that Ricky Beaver
    had been communicating with some of the other area
    concrete producers. Moreover, Allyn testified that he
    knew that Christopher had attended the October 2003
    meeting at Nuckols’s horse barn, that Christopher told
    him that those in attendance talked about prices, and
    that “the way that the meeting was going,” it seemed
    like that the attendees “must be doing this all the time.”
    However, Allyn did not know whether Christopher entered
    into any agreement with Beaver Materials’s competitors.
    Sheeks then testified that the day after the FBI con-
    ducted its interviews, he met with Christopher Beaver,
    Ricky Beaver, and Allyn Beaver at Beaver Materials’s
    corporate office. There, Christopher and Ricky told Sheeks
    that they lied to the FBI about their presence at the
    meetings at Nuckols’s horse barn. In response to this
    news, Sheeks sent a letter to the Department of Justice
    on May 28, in which he stated only that “[o]ne of the
    employees of my client made a misstatement to one of
    your agents to the effect he had not attended a meeting
    at what has been referred to as ‘Butch’s barn.’ He did, in
    fact, attend the meeting.”
    After the defense rested the district court submitted
    the case to the jury, which found Christopher Beaver
    guilty on both the price-fixing-conspiracy and false-state-
    10                                               No. 07-1381
    ments counts.2 Christopher then renewed his motion for
    a judgment of acquittal, see Fed. R. Crim. P. 29(c), chal-
    lenging the evidence supporting his price-fixing-con-
    spiracy conviction, but not his conviction for making
    false statements. After the court denied the motion, it
    sentenced Christopher to 27 months’ imprisonment.
    II. ANALYSIS
    Christopher Beaver raises two arguments on appeal.
    First, he argues that the district court erred by denying
    his motion for a judgment of acquittal because, he asserts,
    the government failed to prove at trial that a price-fixing
    conspiracy existed, or that he participated in the conspir-
    acy. Christopher also challenges his false-statements
    conviction by asserting that the government failed to
    prove that the lies he told to Special Agent Freeman
    were material “as a matter of law.” We address these
    arguments in turn.
    A. The Existence of, and Christopher Beaver’s Participa-
    tion in, the Price-Fixing Conspiracy
    To prevail on his argument that the district court erred
    by denying his motion for a judgment of acquittal, Christo-
    pher Beaver must show that the court incorrectly con-
    cluded that there was sufficient evidence to sustain his
    conviction under the Sherman Antitrust Act. See Fed. R.
    Crim. P. 29(a); Andreas, 
    216 F.3d at 670
    . Although we
    review Christopher’s argument de novo, see United States
    v. O’Hara, 
    301 F.3d 563
    , 569 (7th Cir. 2002), he faces a
    “ ‘nearly insurmountable’ ” burden on appeal, United States
    2
    The jury also found Beaver Materials and Ricky Beaver guilty
    on all counts.
    No. 07-1381                                                   11
    v. Jackson, 
    177 F.3d 628
    , 630 (7th Cir. 1999) (quoting
    United States v. Moore, 
    115 F.3d 1348
    , 1363 (7th Cir.
    1997)). Viewing the evidence presented at trial in the
    light most favorable to the government, we will overturn
    Christopher’s guilty verdict “ ‘only if the record contains
    no evidence, regardless of how it is weighed,’ ” from
    which the jury could have concluded beyond a reasonable
    doubt that he is guilty. See Andreas, 
    216 F.3d at 670
    (quoting United States v. Agostino, 
    132 F.3d 1183
    , 1192
    (7th Cir. 1997)).
    Christopher Beaver attempts to shoulder this burden by
    arguing that the government failed to prove that the
    concrete producers agreed to restrict their discounts on
    the net prices of concrete. Specifically, he contends
    that the evidence at trial showed that “no person voiced
    their assent to the supposed conspiracy.” Thus, according
    to Christopher, the government failed to establish
    that the producers entered into an agreement in the
    first place.3
    To prove a violation of § 1 of the Sherman Antitrust Act,
    the government had to introduce evidence showing that
    the concrete producers conspired to restrain trade, see
    
    15 U.S.C. § 1
    ; United States v. Socony-Vacuum Oil Co.,
    
    310 U.S. 150
    , 224 & n.59 (1940); Andreas, 
    216 F.3d at 666
    ; United States v. Hayter Oil Co., 
    51 F.3d 1265
    , 1270
    3
    Although Christopher argues that the government failed to
    show that the concrete producers agreed to limit their net-price
    discounts, he abandons any challenge to the illegality of the
    agreement itself. See Crestview Vill. Apartments v. U.S. Dep’t of
    Hous. & Urban Dev., 
    383 F.3d 552
    , 555 (7th Cir. 2004). This is
    wise; the net-price-discount limit constituted an illegal price-
    fixing arrangement, and thus was a per se illegal restraint of
    trade under § 1 of the Sherman Antitrust Act. See Texaco Inc. v.
    Dagher, 
    547 U.S. 1
    , 5-7 (2006); United States v. Kahan & Lessin
    Co., 
    695 F.2d 1122
    , 1125 (9th Cir. 1982).
    12                                             No. 07-1381
    (6th Cir. 1995), by agreeing to fix the price of concrete
    through limiting their net-price discounts, see Texaco Inc.,
    
    547 U.S. at 5-7
    ; Kahan & Lessin Co., 
    695 F.2d at 1125
    ;
    United States v. Am. Radiator & Standard Sanitary
    Corp., 
    433 F.2d 174
    , 185-87 (3d Cir. 1970). Although the
    existence of such an agreement is “the essence” of the
    government’s § 1 conspiracy allegation, see United States
    v. Consol. Packaging Corp., 
    575 F.2d 117
    , 126 (7th Cir.
    1978); see also Nelson v. Pilkington, 
    385 F.3d 350
    , 356-57
    (3d Cir. 2004), the government did not need to show that
    the producers reached a “formal agreement” to limit their
    discounts, Am. Tobacco Co. v. United States, 
    328 U.S. 781
    ,
    809 (1946); see also United States v. Whaley, 
    830 F.2d 1469
    , 1474 (7th Cir. 1987). Rather, the government was
    required only to establish that the concrete producers
    had “a tacit understanding based upon a long course of
    conduct” to limit their discounts. United States v. Beachner
    Constr. Co., 
    729 F.2d 1278
    , 1283 (10th Cir. 1984); see
    also Andreas, 
    216 F.3d at 670
    ; cf. Monsanto Co. v.
    Spray-Rite Serv. Corp., 
    465 U.S. 752
    , 764 (1984) (“[T]he
    antitrust plaintiff should present direct or circumstan-
    tial evidence that reasonably tends to prove that the
    manufacturer and others ‘had a conscious commitment
    to a common scheme designed to achieve an unlawful
    objective.’ ” (quoting Edward J. Sweeney & Sons, Inc. v.
    Texaco, Inc., 
    637 F.2d 105
    , 111 (3d Cir. 1980))).
    The government introduced ample evidence at trial
    that showed that the concrete producers shared a “tacit
    understanding” that they were to limit their net-price
    discounts collectively. In fact, the trial record is replete
    with details regarding the cartel’s meetings in July 2000,
    May 2002, and October 2003, at which the producers
    discussed the net-price-discount limit, policing the
    limit, and other price restraints. Haehl, Nuckols, Irving,
    and Hughey each testified that, beginning in July 2000,
    the entire cartel met on at least three occasions with the
    No. 07-1381                                               13
    known purpose of addressing the falling price of concrete.
    During each of those meetings, the competitors discussed
    the ways in which they could “stabilize the market,”
    leading to the proposed net-price-discount limit. And
    although no formal vote was taken on the discount limit,
    no one disagreed with the proposal or stated that he
    would not participate in the scheme. Indeed, when Hughey
    gave the producers the opportunity to oppose the price-
    fixing arrangement and leave the conspiracy, “Nobody
    objected, nobody disagreed, nobody walked away.” Instead,
    the producers discussed additional methods of aligning
    their pricing practices, such as instituting general price
    increases and a winter surcharge. And based on these
    meetings and related discussions, Haehl, Nuckols, Irving,
    and Hughey each understood that an agreement was
    reached. See Andreas, 
    216 F.3d at 670
    ; Beachner Constr.
    Co., 
    729 F.2d at 1282
    .
    Moreover, Haehl, Nuckols, Irving, and Hughey each
    testified that the concrete producers’ communications
    were not limited to the July 2000, May 2002, or Oct-
    ober 2003 meetings; they also enforced the discount
    restraint by confronting those who were cheating on the
    cartel. Each witness also testified that, on various occa-
    sions, they either confronted someone whom they believed
    was cheating or were themselves accused of cheating.
    Hughey likewise stated that on two separate occasions
    Christopher Beaver reassured him that Beaver Materials
    was abiding by the discount limit. In the face of this
    evidence, Christopher’s assertion that “no person voiced
    their assent to the supposed conspiracy” rings hollow.
    Such assent was voiced when the co-conspirators either
    confronted others about cheating on the cartel, or reas-
    sured others—like Christopher did—that they were
    abiding by the agreement. See Beachner Constr. Co., 
    729 F.2d at 1282
    ; cf. In re High Fructose Corn Syrup Antitrust
    Litig., 
    295 F.3d 651
    , 654 (7th Cir. 2002) (stating that price-
    14                                              No. 07-1381
    fixing conspiracy can be proved by “actual, verbalized
    communication”).
    Christopher Beaver asserts, however that the concrete
    producers’ occasional cheating on the discount limit
    shows that no agreement was ever reached. But this
    argument is illogical; certainly Christopher would agree
    that a breach of contract does not mean that the parties
    never entered into the contract in the first place. And the
    argument is also beside the point because § 1 of the
    Sherman Antitrust Act does not outlaw only perfect
    conspiracies to restrain trade. It is not uncommon for
    members of a price-fixing conspiracy to cheat on one
    another occasionally, and evidence of cheating certainly
    does not, by itself, prevent the government from proving a
    conspiracy. See, e.g., Andreas, 
    216 F.3d at 679
     (stating
    that cheating cartel members did not negate conspiracy);
    United States v. Misle Bus & Equip. Co., 
    967 F.2d 1227
    ,
    1231 (8th Cir. 1992) (“Government witnesses testified that
    although [the defendant] occasionally ‘cheated’ his co-
    conspirators by bidding lower than was agreed,
    he . . . reached mutual understandings with the other
    participants about prices . . . and usually adhered to the
    prices and market allocations upon which they agreed.”);
    United States v. Foley, 
    598 F.2d 1323
    , 1333 (4th Cir. 1979)
    (“Since the agreement itself, not its performance, is the
    crime of conspiracy, the partial non-performance of [the
    defendant company] does not preclude a finding that it
    joined the conspiracy.” (citations omitted)). Thus, we
    cannot say that the producers’ occasional cheating pre-
    vented the government from sufficiently proving that
    they conspired to fix the price of concrete.
    Christopher Beaver continues his challenge to the
    sufficiency of the evidence underlying his price-fixing-
    conspiracy conviction by arguing that the government
    failed to show that he personally participated in the cartel.
    No. 07-1381                                               15
    In Christopher’s view, the testimony of Haehl, Nuckols,
    Irving, and Hughey implicating him in the conspiracy
    was not credible because “no two competitors said any-
    thing as a whole which would corroborate the testimony
    of the others.” But this argument fails from the start. “We
    will not second-guess the jury’s credibility decisions in
    evaluating [Christopher’s] challenge to the sufficiency of
    the evidence,” United States v. Johnson-Dix, 
    54 F.3d 1295
    ,
    1306 (7th Cir. 1995); United States v. Henderson, 
    58 F.3d 1145
    , 1148 (7th Cir. 1995), even if his co-conspirators’
    claims were uncorroborated, see United States v. Crowder,
    
    36 F.3d 691
    , 696 & n.1 (7th Cir. 1994).
    But the credibility of Haehl, Nuckols, Irving, and
    Hughey aside, their testimony sufficiently implicated
    Christopher Beaver in the conspiracy. Specifically, each
    man testified that Christopher (1) was present at the
    October 2003 meeting at Nuckols’s horse barn; (2) partici-
    pated in discussions on how to limit the price of concrete;
    (3) did not object to the net-price-discount limit; (4) agreed
    to confront other conspiracy members if he found them
    cheating on the agreement; and (5) agreed on additional
    pricing constraints. Moreover, Hughey testified that, at
    the meeting, Christopher volunteered to contact the
    manager at American Concrete “and get him the message
    on what we agreed on.”
    Looking beyond the testimony of Haehl, Nuckols,
    Irving, and Hughey, the uncontradicted evidence regarding
    Christopher Beaver’s responsibilities at Beaver Materials
    further bolsters the jury’s conclusion that he par-
    ticipated the conspiracy. Christopher admitted to Special
    Agent Freeman that, as Operations Manager, he was
    involved in the pricing of the company’s products, a role
    that would have allowed the jury to infer that Christopher
    was able to effectuate the net-price-discount limit. This
    inference is further supported by Hughey’s testimony
    that he spoke with Christopher personally on two occa-
    16                                              No. 07-1381
    sions, and that during those conversations Christopher
    reaffirmed Beaver Materials’s commitment to the dis-
    count limit. And the testimony of both Mosely and Allyn
    Beaver failed to contradict the evidence of Christopher’s
    involvement. Both men stated that they knew
    that Christopher had met with competitors at Nuckols’s
    horse barn in October 2003, and Allyn further stated
    that Christopher told him that pricing was discussed at
    that meeting. We thus cannot say that the government
    failed to prove that Christopher participated in the price-
    fixing conspiracy, or that the district court erred by
    denying his motion for a judgment of acquittal. See
    Andreas, 
    216 F.3d at 670
    .
    B. Christopher Beaver’s False Statements
    Christopher Beaver next challenges his conviction under
    
    18 U.S.C. § 1001
    (a)(1) for falsely stating to Special Agent
    Freeman that neither he, nor Beaver Materials, partici-
    pated in the price-fixing conspiracy. Specifically, Christo-
    pher argues that the government did not prove that his
    statements were material “as a matter of law.” As he
    explains, the government needed to show at trial that his
    statements to Freeman were material, see 
    18 U.S.C. § 1001
    (a)(1); United States v. Moore, 
    446 F.3d 671
    , 677 (7th
    Cir. 2006), meaning that the statements had the tendency
    to influence, or were capable of influencing, the FBI’s
    investigation of the price-fixing conspiracy, see United
    States v. Brantley, 
    786 F.2d 1322
    , 1326 (7th Cir. 1986);
    United States v. Di Fonzo, 
    603 F.2d 1260
    , 1266 (7th Cir.
    1979); cf. United States v. Fernandez, 
    282 F.3d 500
    , 508
    (7th Cir. 2002) (explaining materiality in context of federal
    No. 07-1381                                                  17
    mail-fraud statutes, 
    18 U.S.C. §§ 1341
     and 1346).4 Accord-
    ing to Christopher, his false statements could not have
    influenced the FBI’s investigation because his attorney,
    Sheeks, contacted the Department of Justice to correct
    the statements before they could lead the FBI astray.
    Before we weigh the merits of Christopher Beaver’s
    argument, however, we must take a moment to alleviate
    the confusion that apparently exists regarding his chal-
    lenge. Specifically, Christopher mischaracterizes the
    issue of his false statements’ materiality as “a matter of
    law.” But the materiality of false statements is not a
    legal determination; it is, rather, a factual determination
    that is made by the jury only. As the U.S. Supreme Court
    explained in United States v. Gaudin, 
    515 U.S. 506
    , 522-23
    (1995), the Sixth Amendment guarantees a criminal
    defendant’s right to have a jury decide each and every
    element of the offense with which he is charged, in-
    cluding the element of materiality when the defendant is
    charged with making false statements. See also United
    States v. Ringer, 
    300 F.3d 788
    , 791-92 (7th Cir. 2002);
    Waldemer v. United States, 
    106 F.3d 729
    , 730-31 (7th Cir.
    4
    In all, the government was required to prove at trial that
    (1) Christopher Beaver made a statement, or had a duty to
    disclose the information; (2) the statement was false, or that
    Christopher undertook acts amounting to concealment; (3) the
    statement or concealed facts were material; (4) Christopher
    made the statement or concealed the facts knowingly and
    willfully; and (5) the statement or concealed information con-
    cerned a matter within the jurisdiction of a federal department
    or agency. See 
    18 U.S.C. § 1001
    (a)(1); Moore, 
    446 F.3d at 677
    .
    Christopher, however, asserts only that the government failed to
    establish the materiality of his false statements. Thus, he has
    abandoned any further challenge to the sufficiency of the
    evidence underlying his false-statements conviction. See
    Crestview Vill. Apartments, 
    383 F.3d at 555
    .
    18                                            No. 07-1381
    1996); United States v. Ross, 
    77 F.3d 1525
    , 1538-39 (7th
    Cir. 1996). Indeed, the jury in Christopher’s trial was
    instructed specifically to determine whether the govern-
    ment proved beyond a reasonable doubt that the false
    statements he made to Special Agent Freeman were
    material, and, by virtue of its guilty verdict, concluded
    that they were. Accordingly, Christopher’s argument
    that the government failed to prove that his false state-
    ments were material requires us to examine whether
    the government introduced sufficient evidence to support
    the jury’s conclusion. See Moore, 
    446 F.3d at 676-80
    ;
    United States v. Kosth, 
    257 F.3d 712
    , 718-20 (7th Cir.
    2001); see also Ringer, 
    300 F.3d at 791-92
    .
    The government, in turn, contends that Christopher
    Beaver has “waived” any challenge to the sufficiency of the
    evidence supporting his false-statements conviction. As
    the government points out, Christopher did not chal-
    lenge the evidence showing that he lied to Special Agent
    Freeman either when he moved for a judgment of ac-
    quittal at the close of the government’s case, or when he
    renewed his motion after the jury’s verdict; instead, he
    challenged only the evidence supporting his price-fixing-
    conspiracy conviction. Thus, the government asserts,
    Christopher intentionally relinquished the argument that
    insufficient evidence supported his false-statements
    conviction by failing to raise it specifically before the
    district court, and that such a “waiver” precludes our
    review of this argument.
    The government is correct that Christopher Beaver
    “waived” his sufficiency-of-the-evidence argument regard-
    ing his false-statements conviction. See United States v.
    Groves, 
    470 F.3d 311
    , 324 (7th Cir. 2006); United States v.
    Buchmeier, 
    255 F.3d 415
    , 419 (7th Cir. 2001); see also 2A
    Charles Alan Wright, Federal Practice & Procedure:
    Criminal § 466 (3d. 2000). However, the government
    No. 07-1381                                               19
    incorrectly asserts that Christopher’s failure to raise the
    point in his motion for a judgment of acquittal prevents us
    from addressing the argument on appeal; as we have
    stated many times, we review sufficiency-of-the-evidence
    arguments that were not presented in a motion for a
    judgment of acquittal under the plain-error standard. See,
    e.g., Groves, 
    470 F.3d at 324
    ; United States v. Allen, 
    390 F.3d 944
    , 947 (7th Cir. 2004); United States v. Baker, 
    40 F.3d 154
    , 160 (7th Cir. 1994). In this regard, the failure to
    challenge the sufficiency of the evidence is perhaps more
    precisely characterized as forfeiture rather than “waiver.”
    Cf. United States v. Brodie, 
    507 F.3d 527
    , 530-31 (7th Cir.
    2007) (differentiating between “waiver” and “forfeiture” in
    context of Fed. R. Crim. P. 12). Compare Groves, 
    470 F.3d at 324
     (stating that sufficiency-of-evidence argument not
    presented in motion for judgment of acquittal is “waived,”
    but nevertheless reviewed under plain error), with United
    States v. Moore, 
    425 F.3d 1061
    , 1069 n.5 (7th Cir. 2005)
    (“ ‘Waiver precludes appellate review, but forfeiture
    permits review for plain error.’ ” (quoting United States v.
    Jaimes-Jaimes, 
    406 F.3d 845
    , 847 (7th Cir. 2005))). But
    regardless of what we call Christopher’s failure to raise his
    challenge before the district court, we nevertheless proceed
    with a plain-error analysis, see Groves, 
    470 F.3d at 324
    ;
    Allen, 
    390 F.3d at 947
    , meaning that Christopher can
    prevail only if he can show that, “absent reversal, a
    manifest miscarriage of justice will result,” Allen, 
    390 F.3d at 947
    ; see also United States v. Rock, 
    370 F.3d 712
    , 714
    (7th Cir. 2004). Under this “most demanding standard,
    reversal is warranted only ‘if the record is devoid of
    evidence pointing to guilt, or if the evidence on a key
    element was so tenuous that a conviction would be shock-
    ing.’ ” Allen, 
    390 F.3d at 948
     (quoting United States v.
    Taylor, 
    226 F.3d 593
    , 597-98 (7th Cir. 2000)).
    Moving (finally) to the merits of Christopher Beaver’s
    argument, we reject his assertion that his false state-
    20                                            No. 07-1381
    ments were not capable of influencing the FBI’s investiga-
    tion because his attorney, Sheeks, contacted the Depart-
    ment of Justice to correct the statements before the
    FBI could actually be influenced by them. In fact, the
    argument fails for several reasons. First, the record does
    not even support Christopher’s contention that he at-
    tempted to correct his false statements. The letter Sheeks
    sent to the Department of Justice did not say that Christo-
    pher made false statements to the FBI; the letter merely
    stated that “one of the employees” of Beaver Materials
    “misstated” that “he” was not at a meeting at Nuckols’s
    horse barn. This “correction” could be understood as
    referring to Christopher, Ricky Beaver, Allyn Beaver, or
    any employee at Beaver Materials that spoke with FBI
    agents on May 25, 2004, but not as an admission by
    Christopher, himself, that he misled the FBI. Instead,
    the letter’s vague language perpetuated Christopher’s
    lies by implying that someone else had misled the FBI.
    Moreover, Christopher Beaver is incorrect that he can
    avoid a conviction under § 1001 by correcting his false
    statements days after he spoke them. Contrary to Christo-
    pher’s suggestions, § 1001 contains no recantation defense.
    See United States v. Sebaggala, 
    256 F.3d 59
    , 64 (1st Cir.
    2001). Christopher nevertheless attempts to impute
    such a defense by citing one case in which a circuit court
    of appeals held that a criminal defendant can escape
    prosecution under § 1001 by correcting false statements
    “almost immediately”—United States v. Cowden, 
    677 F.2d 417
    , 420 (8th Cir. 1982). But Christopher did not at-
    tempt to cure his false statements “almost immediately”;
    Sheeks did not send the letter on Christopher’s behalf to
    the Department of Justice until three days after Christo-
    pher lied to Special Agent Freeman. Cf. United States v.
    Salas-Camacho, 
    859 F.2d 788
    , 792 (9th Cir. 1988) (distin-
    guishing Cowden and declining to find false statements
    immaterial when defendant corrected statements only
    No. 07-1381                                               21
    when confronted by federal agents); United States v. Fern,
    
    696 F.2d 1269
    , 1275 (11th Cir. 1983) (distinguishing
    Cowden and declining to find false statements immaterial
    when defendant corrected statements only once Internal
    Revenue Service became suspicious). Christopher’s reliance
    on Cowden is thus misplaced, and absent any further
    support he essentially asks us to interpolate a recantation
    defense into § 1001. But given Congress’s silence on the
    issue, we decline his invitation to do so. See Sebaggala, 
    256 F.3d at 64
     (“[W]e see no basis for writing into section 1001
    a recantation defense that Congress chose to omit. After
    all, ‘courts may not create their own limitations on legisla-
    tion, no matter how alluring the policy arguments for
    doing so.’ ” (quoting Brogan v. United States, 
    522 U.S. 398
    ,
    408 (1998))).
    Because § 1001 contains no recantation defense, the
    materiality of Christopher Beaver’s false statements
    must be assessed at the moment he uttered them. See
    United States v. Lee, 
    359 F.3d 412
    , 417 (6th Cir. 2004);
    United States v. Sarihifard, 
    155 F.3d 301
    , 307 (4th Cir.
    1998) (stating that not measuring materiality of false
    statement at time of utterance would “allow witnesses who
    lie under oath to escape prosecution if their statements
    before a grand jury are obviously false”). And in so assess-
    ing the false statements, we conclude that they were
    material. Special Agent Freeman testified that
    Christopher denied meeting with any of Beaver Materials’s
    competitors to develop discount limits or pricing con-
    straints. According to Freeman, Christopher went so far
    as to say that the only time that he saw Beaver Materials’s
    competitors was at Indiana Ready-Mix Association meet-
    ings. Because Christopher’s statements concealed his
    actual role in the conspiracy, they could have hindered the
    FBI’s investigation by directing its attention away from
    the October 2003 meeting at Nuckols’s horse barn, away
    from Beaver Materials as a company involved in the
    cartel, and away from himself as an individual participant

    in the conspiracy. Thus, we see no fault with the jury’s
    determination that Christopher’s false statements were
    material, much less can we say that we are shocked by his
    conviction. See Moore, 
    446 F.3d at 676-80

    III. CONCLUSION
    We AFFIRM Beaver’s price-fixing-conspiracy conviction
    under 
    15 U.S.C. § 1
    , and his false-statements conviction
    under 
    18 U.S.C. § 1001
    (a)(1).

    Beaver also asks us to grant him “amnesty” to reward the
    “affirmative steps” he took “to alleviate the harm” caused by his
    lies. But for the same reasons we will not impute a recantation
    defense into § 1001, see Sebaggala, 
    256 F.3d at 64
    , we will not
    create out of whole cloth an amnesty doctrine applicable to
    Beaver’s wrongdoings, particularly when such a doctrine
    would essentially reward Beaver’s instinct to lie to federal
    authorities about his role in the price-fixing conspiracy, cf.
    Brogan, 
    522 U.S. at 408
     (“Courts may not create their own
    limitations on legislation, no matter how alluring the policy
    arguments for doing so, and no matter how widely the blame
    may be spread.”).
