    OPINION
    _________________
    ROGERS, Circuit Judge. In this securities fraud action, the plaintiffs contend
    that BioMimetic Therapeutics, Inc. misled investors about Augment Bone Graft’s
    prospects for Federal Drug Administration (FDA) approval. According to the plaintiffs,
    the FDA privately communicated to BioMimetic that the FDA expected the device’s
    clinical trials to prove that Augment was effective based on an analysis of all of the
    study’s participants. The clinical trials did not achieve those results. But if BioMimetic
    removed from its analysis study participants that did not actually receive treatment, then
    the data did indicate that the device was effective. Based on these two analyses,
    BioMimetic expressed optimism about Augment’s chances for FDA approval to
    investors.    The plaintiffs claim that those statements were misleading because
    BioMimetic did not tell investors everything it knew about the FDA’s
    expectations—particularly the FDA’s desire for the trials to show that the device was
    effective based on an analysis of the entire study population. However, the plaintiffs’
    complaint does not plead a strong enough inference of scienter, and therefore the district
    court did not err in granting BioMimetic’s motion to dismiss the plaintiffs’ complaint.
    BioMimetic develops and manufactures products that help heal damaged bones
    and muscles. Augment is one of the company’s flagship products; it is designed to
    encourage bone growth in patients that undergo foot and ankle surgeries. Historically,
    doctors treated these damaged bones and muscles by transplanting healthy tissue from
    one part of the patient’s body to the damaged area via a process known as an autograft.
    Augment is different from an autograft because the device promotes bone growth via
    drugs and can be done in a single operation, while autografts require conducting a
    second surgery to harvest the material from another part of the patient’s body. If
    Augment works as intended, the device will obviate the need for a surgeon to conduct
    the second surgery.
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.           Page 3
    Before BioMimetic can sell Augment in the United States, the FDA must
    approve the device. Obtaining FDA approval requires a company (known as a sponsor
    in this context) to navigate the complex premarket approval process. To receive
    premarket approval, a sponsor must conduct clinical trials that demonstrate the device’s
    efficacy and safety. Before obtaining permission to conduct the clinical trials, the
    sponsor must receive FDA clearance to test the device on humans. And before the FDA
    will grant its permission to conduct those tests, the sponsor must submit a proposed
    study plan that governs how the study will be performed and its data analyzed. This plan
    is known as a protocol. Sometimes the FDA will object to the initial protocol proposed
    by the sponsor and will issue a conditional approval letter that allows the trials to begin
    but that requires refinement of the protocol. In those cases, the sponsor will need to
    supplement its proposed protocol to address the FDA’s concerns.
    After the sponsor completes the clinical trials, it can submit an application for
    premarket approval to the FDA.       If the agency detects potential problems with the
    application, it can issue a “deficiency letter” that asks the sponsor to address any
    problems the letter identified. The FDA can also choose to refer the premarket approval
    application to a panel of outside experts. After a public meeting, these experts vote on
    whether they think the device is safe, effective, and whether its benefits outweigh its
    risks. If the device makes it through all of these steps, then the FDA itself will decide
    whether or not it will approve the device. The FDA is not bound by the expert panel’s
    recommendation and can choose to approve the device or declare it “not approvable.”
    BioMimetic filed for permission to conduct clinical trials in June 2005. The
    protocol submitted with that application proposed that the “primary effectiveness
    analysis” (i.e., the analysis that would determine whether Augment was effective relative
    to a control group of patients receiving a traditional autograft implant) would be
    conducted based on an intent-to-treat (ITT) population. An ITT population includes
    every patient that is randomly assigned to a treatment group (in this case, either
    Augment or an autograft). By contrast, a modified intent-to-treat (mITT) population is
    a subset of the ITT population that excludes individuals that meet certain criteria (e.g.,
    No. 13-5602          Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.         Page 4
    patients that are initially assigned a treatment group but that do not actually receive
    treatment).
    The FDA approved Augment for clinical trials, but wanted BioMimetic to revise
    its protocol. BioMimetic submitted a supplement that included an amended definition
    of “intent to treat” on April 16, 2007. The supplement stated: “The Intent-to-Treat (ITT)
    population is defined as all randomized subjects who received treatment post
    randomization. Patients who are randomized and unable to be treated will be considered
    as surgical screening failures and will not [be] included in the Intent-to-Treat (ITT)
    patient population.” This was not a standard definition of ITT. Because the proposed
    definition excluded patients that were randomly sorted into treatment groups, the
    definition did not actually describe an ITT population. Rather, the population that
    BioMimetic proposed to analyze for its primary effectiveness analysis would more
    accurately be described as an mITT population. Thus what BioMimetic was proposing
    to do, albeit in a somewhat roundabout way, was analyze an mITT population rather than
    an ITT population.
    BioMimetic’s proposed change was not lost on the FDA. In a May 18, 2007
    letter, the FDA wrote that BioMimetic had “corrected the deficiencies cited in our . . .
    conditional approval letter,” and approved the April 16 supplement (which contained the
    proposed change from ITT to mITT). But the letter also explicitly addressed the new
    definition of ITT. The FDA wrote:
    You should also give serious consideration to the following items which
    are considered essential for the analysis of your data for the purposes of
    determining safety and effectiveness for a future PMA application: . . .
    2. The Intent-to-Treat population should be defined as all
    randomized subjects in the treatment groups to which they were
    assigned, regardless of whether they actually received the assigned
    treatment or not. All subjects should be analyzed as randomized even if
    no treatment or other treatment was actually received. You may analyze
    additionally a group of patients excluded from the ITT due to “surgical
    screening failure” . . . ; however, this should be considered and referred
    to as a “modified ITT” population versus the “ITT” population (i.e., “true
    ITT” population) defined above. You should plan to analyze the true
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.            Page 5
    ITT population. You may also analyze a modified ITT (i.e., patients with
    “surgical screening failures” who are excluded from the ITT) and the
    per-protocol population.
    BioMimetic proceeded to conduct clinical trials over the next couple of years.
    The trials ended and BioMimetic issued a press release summarizing the study’s results
    on October 13, 2009. That date is the beginning of the class period. According to the
    release, Augment was effective when an mITT population was analyzed (i.e., the trial
    produced statistically significant results), but not when the analysis was conducted on
    the ITT population.
    The company addressed the conflicting results of the study in a phone call with
    investors that same day. In response to an analyst who asked whether the FDA would
    consider only the ITT results, Russ Pagano, BioMimetic’s Vice-President for Clinical
    and Regulatory Affairs said:
    So, does FDA look at the ITT? No. FDA really looks at the
    totality of the dataset, and I think if you do that here, regardless of how
    you weight anything, you would see a classic—kind of classic pattern of
    a noninferiority outcome in that you’re going to have a number of
    outcomes. If you’re truly noninferior to a product in that just typically
    you’re going to have a couple that probably do not make it statistically
    and hopefully you’ll have the bulk that do. So, I think from a statistical
    point of view, we kind of hit the classic pattern of what you would
    expect.
    FDA—that said, FDA does look at everything. They also said
    our protocol calls out for we pre-specified [sic], as we talked about the
    takeouts, if you will, from the MITT. FDA approved that. However,
    what they do, just to be totally transparent, they frequently in approval
    letters will put what they call PMA advisories, where they then make
    some suggestions of things you should do per your PMA. It’s in one of
    these PMA advisories that they state that they would like to see a true
    traditional ITT, which basically includes everybody.
    Pagano and Samuel Lynch, BioMimetic’s President and CEO, also argued that there
    was regulatory precedent for conducting an analysis on an mITT population. They
    explained that Medtronic had obtained approval for a device based on an analysis similar
    to the one BioMimetic had used. Finally, BioMimetic argued to investors that the mITT
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.          Page 6
    results were more relevant from a clinical perspective, and that the company had defined
    who would be excluded from the mITT population before the trials began in order to
    avoid injecting bias into the study (the principal danger of using an mITT rather than an
    ITT population).
    The market reacted negatively after the company released the study data: shares
    fell 16% in after-hours trading after the results of the study were revealed. The price of
    BioMimetic stock subsequently experienced a “roller coaster ride” as investors grappled
    with the implications of the results.
    The clinical trials had other problems as well. According to the plaintiffs,
    BioMimetic enrolled an insufficient number of participants in the study, compromised
    the trial’s effectiveness data by failing to provide baseline imaging against which to
    compare post-surgical results, allowed an abnormally high number of protocol
    deviations, damaged the integrity of the study by losing documentation, failed to perform
    pharmacokinetics studies, neglected to monitor patients who experienced increased
    antibody production as a result of being exposed to a human growth factor used by
    Augment until their antibodies returned to baseline levels, declined to conduct
    reproductive studies on the potential effects of exposure to Augment’s human growth
    factor on pregnant women, and bolstered the study’s safety data by failing to report all
    adverse events in the study.
    After reviewing BioMimetic’s application for premarket approval, the FDA sent
    the company a deficiency letter on September 3, 2010. This letter asked for clarification
    and additional data relating to numerous parts of the application. Notably for the
    purposes of this case, the deficiency letter questioned BioMimetic’s use of an mITT
    population for the primary effectiveness analysis. But in a response letter, BioMimetic
    explained to the FDA that the Agency had approved the analysis of an mITT population
    in the May 18, 2007 letter and reiterated the company’s arguments that the mITT results
    were more relevant and that exclusion of certain patients had not biased the study.
    After BioMimetic responded to the deficiency letter, the FDA sent BioMimetic’s
    premarket approval application to an advisory panel of experts. On May 9, 2011, three
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.          Page 7
    days before the meeting with the panel, the FDA released a briefing document to the
    public. Among other things, the document expressed concern over BioMimetic’s use
    of an mITT population in its analysis. The document explained:
    FDA believes that the ITT analysis population as defined in the PMA
    should be considered the primary analysis. In addition, FDA advised the
    sponsor at the IDE stage that both analysis populations should be
    supportive of non-inferiority. Note that the ITT analysis population
    preserves the benefits of randomization, while the mITT analysis
    population does not (due to excluding subjects for mis-randomization or
    not receiving treatment according to protocol.)
    The briefing document apparently made investors question Augment’s prospects—the
    company’s stock price fell 35% the day the document was released. Despite the
    criticism of the clinical trials in the briefing document, the advisory panel voted to
    recommend that the FDA approve the device, albeit narrowly. Only ten of the eighteen
    panel members voted that Augment’s benefits outweighed its risks. The market reacted
    negatively to the narrow vote, and BioMimetic’s stock price experienced a 10% decline
    from that day to the next. The class period ended three days later on May 15, 2011.
    On January 3, 2012, the FDA issued a non-approvable letter. The letter
    explained that the Agency would not approve Augment unless BioMimetic provided
    additional information about the trials. The FDA’s concerns stemmed at least in part
    from the fact that it concluded that it needed “to evaluate the ‘robustness’ of the data,
    given the differences in the outcome of the intent-to-treat and the modified-intent-to-
    treat patient population analyses.”
    The plaintiffs filed suit on July 6, 2011, approximately two months after the
    release of the briefing document. Their complaint alleges that BioMimetic was aware
    of numerous deficiencies in Augment’s clinical trials, but spoke optimistically to
    investors about the device’s prospects for FDA approval. According to the complaint,
    these rosy assessments amounted to securities fraud. The district court disagreed and
    granted BioMimetic’s motion to dismiss. The court concluded that the plaintiffs had not
    pled facts indicating a strong inference of scienter as required by the Private Securities
    Litigation Reform Act of 1995 (PSLRA) and Tellabs, Inc. v. Makor Issues & Rights,
    No. 13-5602            Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.                     Page 8
    Ltd., 
    551 U.S. 308
    (2007). The district court reasoned that the May 18, 2007 FDA letter
    gave BioMimetic a basis for telling investors that it had permission to analyze an mITT
    population because the letter stated that it approved the supplement where the change
    occurred. The district court also concluded that the company’s disclosures (of the study
    data, during the investor phone call, and in the company’s various SEC filings) were
    extensive enough that no material information was withheld from investors. Thereafter,
    the plaintiffs moved under Rule 59 to alter the court’s order granting the motion to
    dismiss and for permission to amend their pleadings to address the May 18, 2007 letter.
    The plaintiffs attached to the motion a proposed amended complaint that included
    evidence from Dr. Gaurino, an expert on the FDA approval process, and additional
    allegations relating to the May 18, 2007 letter. The district court denied the motion,
    concluding that the plaintiffs had unduly delayed by waiting until after the motion to
    dismiss was granted before asking for permission to amend their complaint. This appeal
    followed.
    The plaintiffs’ complaint did not adequately plead facts giving rise to a strong
    inference of scienter as required by the PSLRA. 15 U.S.C. § 78u-4(b)(2)(A). The
    plaintiffs’ theory is that BioMimetic knew that the Augment clinical trials went poorly,
    but nevertheless spoke favorably about the device’s prospects for FDA approval. In
    particular, the plaintiffs argue that the FDA had privately communicated that it expected
    BioMimetic to obtain statistically significant results based on an analysis of the ITT
    population, but that the company characterized those results as less important than the
    analysis of the mITT population.1
    The plaintiffs’ complaint identifies numerous misleading statements allegedly
    made by the company. Many of those statements cast a favorable light on Augment’s
    clinical trials and the device’s chances for success.                   For example, BioMimetic
    characterized the study as producing “positive top line results,” said that the company
    1
    The plaintiffs argued that other deficiencies in the study, for example the fact that Biomimetic
    did not conduct pharmacokinetics studies, also support an inference of fraud. These arguments are not
    convincing. Unlike the allegations regarding the use of mITT and ITT, there are no allegations supporting
    the notion that the defendants knew that these other supposed deficiencies would hurt Augment’s prospects
    for FDA approval.
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.         Page 9
    was “encouraged by the results seen to date in Augment’s clinical development,” and
    stated that it felt “confident in the PMA [the company] submitted for Augment earlier
    this year.”   The plaintiffs assert that these statements were misleading because
    BioMimetic knew that the FDA expected it to obtain statistically significant results
    based on an ITT population and so the results were not nearly as positive as
    BioMimetic’s statements otherwise suggested. Other statements related directly to
    which population the FDA approved for the primary effectiveness analysis for the
    device. In a 2009 earnings call, the company stated: “we met our pre-specified primary
    endpoint and believe that we have demonstrated a clear picture of non-inferiority,” and
    the company referred to the mITT population as “the pre-specified primary study
    population” in a 2010 press release. These statements were alleged to be false because
    the company knew that mITT was not the approved population.
    The plaintiffs’ complaint does not give rise to a strong inference of scienter.
    According to Tellabs, a court addressing whether a plaintiff has pled a strong enough
    inference of scienter must “take into account plausible opposing inferences” that the
    facts in the complaint 
    generate. 551 U.S. at 323
    . A plaintiff only clears the high hurdle
    imposed by the PSLRA if “a reasonable person [would] deem the inference of scienter
    at least as strong as any opposing inference.” 
    Id. at 326.
    Frank v. Dana Corp., 
    646 F.3d 954
    , 961 (6th Cir. 2011) reemphasizes that we must conduct a holistic review of the
    pleadings. Under such a review, a reasonable person would conclude that the inference
    of scienter in this case is not as strong as the opposing inference. BioMimetic could
    legitimately believe that the statistically significant results it achieved based on an
    analysis of the mITT population would be sufficient to obtain approval by the FDA.
    BioMimetic proposed analyzing an mITT population for its primary effectiveness
    analysis in its April 16, 2007 supplement. The FDA subsequently approved the
    supplement that proposed this change, giving the company reason to believe it had
    permission to conduct the primary analysis on the mITT population. The clinical trials
    occurred, and an analysis based on an mITT population yielded statistically significant
    results, thereby indicating that Augment achieved non-inferiority. The allegations in the
    complaint therefore indicate that the trials showed that the device was effective based
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.         Page 10
    on an analysis that BioMimetic believed the FDA had approved. All of the supposedly
    misleading statements are consistent with that interpretation. While BioMimetic may
    have ultimately been mistaken about which population the FDA wanted the company to
    use for the primary effectiveness analysis, there are no facts suggesting the company
    knew this at the time its representatives spoke.
    The May 18, 2007 letter does not support an inference of scienter. The letter
    does make clear that the FDA expected BioMimetic to conduct an analysis of both a
    “true ITT” and an mITT population. But the letter does not indicate that the FDA
    wanted the primary effectiveness analysis to be conducted on the ITT population.
    Rather, the letter concerns itself with ensuring that BioMimetic defined ITT and mITT
    properly in the premarket approval application by telling the company that the “Intent-
    to-Treat population should be defined as all randomized subjects in the treatment groups
    to which they were assigned, regardless of whether they actually received the assigned
    treatment or not.” The letter says nothing either way about whether ITT must or must
    not serve as the primary benchmark for success.
    The 2010 Deficiency Letter is similarly ambiguous. In the letter, the FDA stated
    that the original protocol called for the primary analysis to be performed using the ITT
    population, that BioMimetic had not justified its switch from ITT to mITT, and that
    using an mITT population risks introducing bias into the analysis. In its response letter,
    BioMimetic explained that it understood the May 18 letter to have meant that the
    primary study population “could be considered a modified intent to treat [population]
    and [be] presented in the PMA” so long as it was labeled as such (i.e., labeled as mITT
    and not ITT). Then BioMimetic proceeded to justify the propriety of analyzing an mITT
    population by making essentially the same arguments it had made to investors when the
    results of the trials were revealed: the company had excluded patients from the mITT
    population in a manner that avoided introducing bias into the study, and an analysis of
    an mITT population was a better indicator of whether the device was effective. It is hard
    to imagine that BioMimetic would risk the agency’s ire by defending its use of mITT as
    the primary population based on the FDA’s prior approval if the FDA had clearly not
    No. 13-5602        Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.        Page 11
    given such approval. Like the May 18, 2007 letter, nothing in the deficiency letter
    indicates that the FDA told BioMimetic to use an ITT population for the primary
    effectiveness analysis.
    The briefing document, by contrast, clearly does state that the primary analysis
    should be based on the ITT population. But this document was released at the end of the
    class period and well after the allegedly misleading statements were made. The
    document does indicate that BioMimetic must have known that the FDA expected ITT
    to be the primary analysis by the end of the class period, but the document has little
    bearing on what the company did or did not know at the time the allegedly misleading
    statements were made, and it does not support a strong inference of scienter. Similarly,
    a district court in California concluded that a complaint did not plead facts creating a
    strong inference of scienter because the complaint did “not allege any facts showing that,
    at the time Defendants made their forward-looking statements, FDA compliance
    problems existed, Defendants actually knew of the[] problems, or that the[] problems
    would preclude FDA approval . . . .” Yanek v. Staar Surgical Co., 
    388 F. Supp. 2d 1110
    ,
    1126 (C.D. Cal. 2005).
    Of course the lack of statistically significant results undoubtedly hurt Augment’s
    prospects—but BioMimetic fully disclosed the results of the study and told investors that
    the FDA wanted to see an analysis of both the ITT and mITT populations. And the
    market apparently understood the significance of the results of the study because
    BioMimetic’s stock price dropped 16% after the company released the data. It is
    doubtful that the company intended to defraud investors in light of its willingness to
    disclose information that harmed its share prices. Other courts have concluded that
    disclosing adverse information to the public negates an inference of scienter. See, e.g.,
    In re Worlds of Wonder Sec. Litig., 
    35 F.3d 1407
    , 1425 (9th Cir. 1994).
    Furthermore, nothing in the record indicates that the FDA declared that the
    presence or absence of statistically significant results in an analysis of the ITT
    population was the FDA’s absolute requirement. According to BioMimetic’s press
    release discussing the non-approvable letter, the FDA sought additional information
    No. 13-5602         Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.         Page 12
    from BioMimetic so that the FDA could “evaluate the ‘robustness’ of the data, given the
    differences in the outcome of the intent-to-treat and the modified intent-to-treat patient
    population analyses.” That statement does not suggest that the lack of statistically
    significant results in the ITT population necessarily doomed Augment in the FDA’s
    eyes. While perhaps the lack of statistically significant results in the ITT population
    played a part in the FDA’s decision, nothing in the relevant materials suggests that the
    company knew those results would be the device’s downfall or that such a lack was so
    obvious an impediment to the device’s success that BioMimetic’s failure to perceive the
    risk of non-approval was reckless—i.e., that the company engaged in “highly
    unreasonable conduct” that was “an extreme departure from the standards of ordinary
    care,” PR Diamonds, Inc. v. Chandler, 
    364 F.3d 671
    , 681 (6th Cir. 2004)
    In fact, several factors indicate that BioMimetic rightfully expressed optimism
    about the device’s prospects. The FDA had previously approved other devices based on
    mITT analyses. Augment proved itself by obtaining regulatory approval in both Canada
    and Australia. BioMimetic had previously succeeded in obtaining approval for GEM
    21S, a product that contained the same drug as Augment. And the advisory panel of
    experts vindicated BioMimetic’s optimism by voting to recommend that the FDA
    approve the device.
    In summary, the more compelling inference that can be drawn from the pleadings
    is that BioMimetic was justified in expressing optimism about Augment’s prospects for
    success despite the lack of statistically significant results produced by an analysis of the
    ITT population. BioMimetic may have ultimately been wrong about which population
    would be analyzed for the primary effectiveness analysis, but a reasonable person would
    more easily than not infer that BioMimetic believed that it had permission to use an
    mITT population for the analysis at the time that it spoke to investors. See 
    Tellabs, 551 U.S. at 323
    . Therefore, the district court properly dismissed the plaintiffs’ complaint.
    The district court moreover did not abuse its discretion in refusing to grant the
    plaintiffs leave to amend their complaint. The plaintiffs asked the district court for
    permission to amend on two occasions: the first time was in the final sentence of their
    No. 13-5602         Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.           Page 13
    brief in opposition to BioMimetic’s motion to dismiss, and the second came in the form
    of a post-judgment motion made after the district court granted the motion to dismiss.
    Although FRCP 15 instructs courts to “freely give leave” to amend, that liberal policy
    does not apply to the plaintiffs’ one-sentence request. A “request for leave to amend
    almost as an aside, to the district court in a memorandum in opposition to the
    defendant’s motion to dismiss is . . . not a motion to amend.” La. Sch. Emps.’ Ret. Sys.
    v. Ernst & Young, LLP, 
    622 F.3d 471
    , 486 (6th Cir. 2010) (internal quotation marks
    omitted). Plaintiffs’ motion contained precisely that kind of throwaway language. The
    final sentence of their memorandum in opposition reads: “Alternatively, Plaintiffs
    request leave to amend the Complaint in the event that the Court finds that it falls short
    of the applicable pleading standards in any respect.” Furthermore, the plaintiffs did not
    submit a copy of the revised complaint at the time they filed their memorandum in
    opposition. Normally, a party seeking an amendment should attach a copy of the
    amended complaint. See Shillman v. United States, 
    221 F.3d 1336
    , 
    2000 WL 923761
    ,
    at *6 (6th Cir. 2000) (unpublished table decision). Both because the plaintiffs did not
    present an adequate motion and because they did not attach a copy of their amended
    complaint, the district court did not abuse its discretion in refusing to allow the plaintiffs
    to amend their complaint based on the final sentence of the plaintiffs’ memorandum in
    opposition.
    The district court also did not abuse its discretion in denying the plaintiffs’ post-
    judgment motion. In this case, the timing of plaintiffs’ motion is relevant. Morse v.
    McWhorter, 
    290 F.3d 795
    , 800 (6th Cir. 2002). Plaintiffs made their motion after the
    district court granted BioMimetic’s motion to dismiss. “[I]n the post-judgment context,
    we must also take into consideration the competing interest of protecting the finality of
    judgments and the expeditious termination of litigation.” 
    Id. (internal quotation
    marks
    omitted). Balancing these interests requires a court to “be particularly mindful of not
    only potential prejudice to the non-movant, but also the movant’s explanation for failing
    to seek leave to amend prior to the entry of judgment.” 
    Id. No. 13-5602
           Kuyat, et al. v. BioMimetic Therapeutics, Inc., et al.         Page 14
    The plaintiffs put forward no good excuse for delaying until after the
    district court’s judgment. The plaintiffs sought to amend their complaint to address
    BioMimetic’s arguments relating to the May 18, 2007 FDA letter by including evidence
    from Dr. Gaurino, an expert on the FDA approval process. But the plaintiffs had access
    to the FDA letter ten months before they filed their post-judgment motion. Furthermore,
    plaintiffs had apparently retained Dr. Gaurino long before the FDA letter was revealed.
    They thus presumably had access to his views on the letter when it was attached to
    BioMimetic’s motion to dismiss. This court has previously explained that a district court
    “acts within its discretion in denying a Rule 15 and a Rule 59 motion on account of
    undue delay—including delay resulting from a failure to incorporate previously available
    evidence.” Leisure Caviar, LLC v. U.S. Fish & Wildlife Serv., 
    616 F.3d 612
    , 616 (6th
    Cir. 2010) (internal quotation marks and alterations omitted).
    The plaintiffs’ excuse—that they had no way of knowing that the May 18, 2007
    letter would factor heavily in the district court’s decision—does not pass muster. Rule
    15’s permissive amendment policy should not permit plaintiffs to “use the court as a
    sounding board to discover holes in their arguments, then reopen the case by amending
    their complaint to take account of the court’s decision.” 
    Id. (internal quotation
    marks
    omitted). We recently rejected a similar argument in Ricker v. Zoo Entm’t, Inc., 534 F.
    App’x 495 (6th Cir. 2013). There, the plaintiff argued that “he ‘was unaware of what
    defects, if any, the Court would perceive in the Complaint,’ and first deserved ‘the
    opportunity to analyze the supposed deficiencies in the Complaint to determine whether
    he [could] cure them.’” 
    Id. at 501.
    The plaintiffs’ explanation in the instant case is
    identical. The district court did not abuse its discretion in Ricker, and neither did the
    court in this case. The propriety of refusing to grant leave to amend is buttressed by the
    fact that the usual liberal standards under Rule 15 do not apply to cases governed by the
    PSLRA. “[T]he purpose of the PSLRA would be frustrated if district courts were
    required to allow repeated amendments to complaints filed under the PSLRA.” Miller
    v. Champion Enters. Inc., 
    346 F.3d 660
    , 692 (6th Cir. 2003).
    For the foregoing reasons, we AFFIRM the judgment of the district court.
