    TORRUELLA, Circuit Judge.            Plaintiff William Kader and
    Lead   Plaintiffs   Morad   Ghodooshim,          Roger    Lam,   and   Laxmikant
    Chudasama (collectively, the "Plaintiffs") sought to represent a
    class of purchasers of securities that Sarepta Therapeutics, Inc.
    ("Sarepta") issued between April 21, 2014, and October 27, 2014
    (the "Class Period").       The Plaintiffs brought securities fraud
    claims   against    Sarepta,    Sarepta's        Chief     Executive    Officer,
    Christopher   Garabedian       ("Garabedian"),           and   Sarepta's    Chief
    Scientific Officer, Edward M. Kaye ("Kaye") (collectively, the
    "Defendants").      According       to    the   Plaintiffs,      the   Defendants
    knowingly or recklessly misled investors about their target date
    for submitting an application to the United States Food and Drug
    Administration ("FDA") for approval of the drug eteplirsen.                   The
    district court dismissed the Plaintiffs' First Amended Complaint
    ("FAC") for failure to state a claim, and then denied them leave
    to file their Proposed Second Amended Complaint ("PSAC").                  We hold
    that the district court did not err in dismissing the FAC or in
    denying Plaintiffs leave to file the PSAC.
    I.   BACKGROUND
    A. The FDA's drug-approval process
    Before we immerse ourselves in the details of this case,
    it is useful to give a brief overview of the process through which
    the FDA reviews and approves drugs.             That process begins when the
    -2-
    sponsor of a new drug submits a New Drug Application ("NDA") to
    the   FDA.     See      21    U.S.C.    §     355(a)-(b);      Corban   v.   Sarepta
    Therapeutics, Inc., 
    868 F.3d 31
    , 34 (1st Cir. 2017) (outlining the
    FDA's approval process).               The FDA then makes the "threshold
    determination" as to whether the NDA is "sufficiently complete to
    permit a substantive review."            21 C.F.R. § 314.101(a)(1).           "If so,
    the FDA accepts the application for filing" and then proceeds to
    "assess[] the merits of the application, deciding whether to
    approve the drug."           
    Corban, 868 F.3d at 34
    (citing 21 C.F.R.
    § 314.101(a)(1),        (f)).          "Approval       generally      requires     the
    application's sponsor to demonstrate the drug's clinical benefit."
    
    Id. (citing 21
    U.S.C. § 355(d)).
    Sponsors    of     certain       drugs    may    avail   themselves    of
    various FDA programs that expedite the review process.                           These
    programs aim to facilitate the availability of critical therapies
    for serious, unmet medical needs.                  For example, upon a sponsor's
    showing of adequate preclinical data, the FDA may grant a drug
    "Fast Track" status.            See 21 U.S.C. § 356(b).                 Among other
    benefits, the sponsors of "Fast Tracked" drugs may interact more
    frequently with the FDA to discuss "the drug's development plan
    and ensure collection of appropriate data needed to support drug
    approval."      U.S.     Food    &     Drug       Admin.,    Fast   Track,   https://
    -3-
    www.fda.gov/ForPatients/Approvals/Fast/ucm405399.htm                         (last
    updated Jan. 4, 2018).
    Fast Tracked drugs may also be eligible for "Accelerated
    Approval."      
    Id. The FDA
      approves   drugs   in   the   Accelerated
    Approval program upon meeting a "surrogate endpoint" or "clinical
    endpoint"    that     is   "reasonably    likely"    to   predict    the    drug's
    clinical benefit.          21 U.S.C. § 356(c).      "For example, instead of
    having to wait to learn if a drug actually extends survival for
    cancer patients, the FDA may approve a drug based on evidence that
    the drug shrinks tumors, because tumor shrinkage is considered
    reasonably likely to predict a real clinical benefit."                   U.S. Food
    &   Drug     Admin.,       Accelerated     Approval,      https://www.fda.gov/
    ForPatients/Approvals/Fast/ucm405447.htm             (last     updated     Jan.   4,
    2018).     This is particularly useful in the case of drugs intended
    to treat diseases with longer courses, when measuring the drug's
    clinical benefit would otherwise require an extended period of
    time.      In such cases, the drug's effect on the surrogate or
    clinical endpoint may be observable much sooner, allowing the FDA
    to determine the drug's efficacy at an earlier juncture.
    Crucially, once the FDA has approved a drug, the drug's
    sponsor may begin to market it.
    -4-
    B. The facts underlying this case
    Except when we indicate otherwise, we draw the following
    facts from the FAC.
    1.
    Duchenne Muscular Dystrophy ("DMD") is a rare genetic
    neuromuscular disorder that primarily affects boys and young men.
    As the result of inadequate production of the protein dystrophin,
    individuals with DMD suffer from progressive muscle loss causing
    severe     disability   and      premature      death.      The   average    life
    expectancy for someone diagnosed with DMD is 27 years.               During the
    Class Period, no approved disease-modifying therapies for DMD
    existed.      Sarepta, however, was developing drug candidates to
    treat DMD, including eteplirsen, the drug around which this case
    revolves.     See 
    Corban, 868 F.3d at 34
    -37 (describing, in the
    context of a case involving a different class period, Sarepta's
    development of eteplirsen).          During the Class Period, Sarepta's
    main competitor, Prosensa Therapeutics, Inc., was also developing
    and seeking approval of a drug candidate to treat DMD.                The first
    company to obtain approval of its drug and succeed in bringing it
    to   market    would    obtain     the    "first    mover    advantage."      In
    pharmaceutical markets, the "first mover" gains a considerable
    advantage     because   doctors     will       quickly   prescribe   the    first
    available drug of a new type, and are unlikely to switch to
    -5-
    prescribing a different drug of the same type that subsequently
    becomes available.
    The FDA granted eteplirsen Fast Track status in 2007. In
    2011, Sarepta began conducting the clinical trials at the center
    of this case.       Study 201, designed as a randomized, double-blind,
    placebo-controlled study involving 12 participants, sought to
    assess the effects of "eteplirsen administered intravenously in
    two different doses over 24 weeks for the treatment of ambulant
    boys with DMD."        The study's participants all underwent muscle
    biopsies at the study's outset and conclusion to determine if the
    amount of dystrophin in their muscle tissue had changed over time
    -- a potential surrogate endpoint by which to assess eteplirsen's
    efficacy.      Study       201's   results   showed   that   "treatment    with
    eteplirsen    met    the    primary   efficacy   endpoint    in   the   study."
    Following these encouraging results, Sarepta began "Study 202," in
    which the same participants received varying dosages of eteplirsen
    for an additional 24 weeks.           All of the muscle biopsy dystrophin
    analysis for both of these studies took place at a single location
    -- Nationwide Children's Hospital in Columbus, Ohio -- with one
    doctor overseeing the entirety of the clinical review.                  Because
    this analysis requires staining muscle samples with a dye that
    makes dystrophin visible, and then viewing and analyzing those
    -6-
    samples in slides, the Plaintiffs aver that it is "inherently
    subjective."
    2.
    On April 21, 2014 -- the first day of the Class Period
    -- Sarepta issued a press release discussing the possibility of
    submitting an NDA for eteplirsen by the year's end.            According to
    the press release, that goal was "based on a guidance letter from
    the [FDA] that proposed a strategy regarding the submission of an
    NDA   for    eteplirsen   under   a     potential   Accelerated      Approval
    pathway."     The press release quoted the FDA's guidance letter,
    which explained that "with additional data to support the efficacy
    and safety of eteplirsen for the treatment of DMD, an NDA should
    be fileable."       The press release also explained that the FDA's
    letter "outlined examples of additional data and analysis that, if
    positive, will be important to enhance the acceptability of an NDA
    filing by addressing areas of ongoing concern in the existing
    dataset."      In   addition,   the   release   noted   that   the   FDA   had
    "expressed     concerns   about       methodological    problems     in    the
    assessments of dystrophin and, 'remain[s] skeptical about the
    persuasiveness of the (dystrophin) data.'"          According to the press
    release, the FDA had stated that, as a result, it was "uncertain
    whether the existing dystrophin biomarker data will be persuasive
    -7-
    enough to serve as a surrogate endpoint that is reasonably likely
    to predict clinical benefit."
    That same day, Sarepta held a conference call with
    investors and analysts to discuss its announcement.                 Per the
    guidance letter, Garabedian explained that with "additional data
    and analysis," Sarepta would be able to "pursue an NDA filing that
    we will plan to submit by the end of this year, for a potential
    early    approval    of   eteplirsen    sometime   in    2015."     But,   he
    cautioned, "the guidance letter described the FDA's reservations
    that the existing data set may not be sufficient to support an NDA
    filing,    or   be   compelling   enough     for   a    favorable   review."
    Garabedian further offered that "[w]e could submit our NDA now on
    the existing data set, but the FDA has highlighted questions and
    concerns," for which reason "we are going to be in a much better
    position if we just wait for some of these additional pieces of
    data."
    Following this announcement, Sarepta shares increased in
    value by 39.26% on unusually heavy trading volume, closing on
    April 21, 2014 at $33.98 per share.          The following day, Sarepta
    announced that it planned to offer up to $100 million of its common
    stock in a public offering.       Then, on April 29, it sold 2,650,000
    shares of common stock in a public offering at a price of $38.00
    -8-
    per   share,       resulting      in   net     proceeds    of     approximately       $94.5
    million.
    On    May    7,    2014,    Garabedian       participated       in   another
    conference call with analysts.                 During that call, he characterized
    the   FDA's    guidance          letter     as    communicating       to    Sarepta,     in
    paraphrased terms:
    [W]e're not telling you you can't submit an NDA
    tomorrow on the existing data set . . . . But we're
    telling you that we've raised enough concerns on the
    existing data set that you would bolster your case
    for an NDA filing and potentially a favorable review
    if you allow us to do a more detailed review of your
    dystrophin methodology [and if you supplement the data
    set].
    In short, Sarepta expressly disclosed that the FDA wanted to do a
    more detailed review of the study's methodology, and get more data,
    and that Sarepta's chances of success for an NDA filing would be
    affected by whether it allowed the FDA to do so.                           Additionally,
    during the same month, the FDA also visited Nationwide Children's
    Hospital -- where Study 201/202 took place -- to review the
    clinical trial site and protocols in place there.
    Then,       on    July     29,     2014,   the    FDA      requested     that
    "independent pathologists at independent labs" review Sarepta's
    primary    dystrophin           endpoint.        Sarepta    did    not     disclose    this
    request to the public during the class period.                        On the same day,
    the director of the FDA's Center for Drug Evaluation and Research
    ("CDER") responded via a statement on the White House's website to
    -9-
    a petition urging the FDA to "say YES to Accelerated Approval for
    safe,   effective   therapies   for   children    with   Duchenne."     Her
    response acknowledged Sarepta's intention of filing an NDA for
    eteplirsen by the end of 2014.
    On August 7, 2014, Garabedian held another conference
    call with investors and analysts.          During that call, he stated
    that "[a]s a reminder, the FDA indicated in its April guidance
    that if, after further detailed review, they were to find the
    currently available dystrophin biomarker data to be adequate, our
    existing dystrophin data set would have the potential to support
    accelerated approval."      After relaying that the FDA had visited
    National Children's Hospital, he added that "we continue to work
    with the FDA to provide greater assurance of the quality and
    reliability of our dystrophin data in anticipation of a potential
    NDA filing decision and potential NDA review next year."
    However, on October 27, 2014 -- the last day of the Class
    Period -- Sarepta issued another press release announcing that it
    had received updated guidance from the FDA regarding its planned
    NDA submission for eteplirsen.        That guidance indicated that the
    FDA   now   required   Sarepta's   NDA    to   include   additional   data,
    including, among other things, "the results from an independent
    assessment of dystrophin images and the 168-week clinical data
    from study 202."    As a result, the press release explained, Sarepta
    -10-
    would not be able to submit an NDA until mid-2015, as opposed to
    its prior target of late 2014.    On the same day, Sarepta executives
    also held a conference call with investors and analysts to convey
    and explain the FDA's concerns.    That day, Sarepta shares declined
    by more than 32%, closing at $15.91 per share, on unusually heavy
    trading volume.
    On October 30, 2014, the FDA issued a public statement
    addressing "questions the agency has received from DMD patients,
    their families, and others in the community who are concerned about
    the timing of the filing of an NDA for eteplirsen."    The statement
    underscored that "[i]n its advice to Sarepta, FDA has consistently
    stated that it would be necessary to include data in its NDA
    demonstrating that eteplirsen increases production of the muscle
    protein dystrophin."   The statement also clarified that during the
    FDA's visit to Nationwide Children's Hospital, "the agency did not
    find any evidence of fraud at this site, as has been perceived by
    some."   However, the FDA also highlighted its concern "that the
    methods used to measure dystrophin were not adequately robust to
    support an NDA submission."      Finally, the statement concluded by
    explaining that the "FDA will continue to work with Sarepta in
    their efforts to provide the data it considers critical to FDA's
    ability to review the NDA and reach a decision on approvability."
    -11-
    3.
    We add the following facts from the PSAC.
    In    May     2015,    after        the    Plaintiffs   brought       this
    securities fraud suit, see infra Section I.C., Sarepta did file an
    NDA for eteplirsen.         The FDA accepted the NDA for filing on
    August 25, 2015.        While the director of the CDER has the sole
    authority to approve an NDA, the FDA may call upon advisory
    committees to provide independent opinions and recommendations
    during the approval process.              The FDA scheduled an advisory
    committee meeting about the eteplirsen NDA for January 22, 2016.
    In anticipation of that meeting, the FDA published a briefing
    document for members of the advisory committee (the "Briefing
    Document").     That document detailed, among other things, the
    concerns that the FDA had communicated to Sarepta prior to and
    during the Class Period.
    So     too,     primarily           for     purposes    of    narrative
    completeness, do we mention the following facts contained neither
    in the FAC nor the PSAC.
    The    district       court    took       judicial   notice   that,    on
    September 19, 2016 -- after briefing on the Plaintiffs' motion for
    leave to amend had concluded, see infra Section I.C. -- the FDA
    announced that it had decided to grant accelerated approval to
    eteplirsen.     Moreover, the Plaintiffs ask us to take judicial
    -12-
    notice that this announcement came after an appeal within the FDA
    to the CDER director's initial decision to grant accelerated
    approval to eteplirsen.     In brief, the Director of CDER's Office
    of Drug Evaluation brought an appeal challenging that decision on
    the basis that Study 201/202 was methodologically inadequate.
    After reviewing the appeal, the FDA Commissioner decided to "defer
    to [the CDER director's] judgment and authority to make the
    decision to approve eteplirsen under the accelerated approval
    pathway."1    Thus, Sarepta was able to begin marketing eteplirsen.
    C. This putative class action
    The Plaintiffs filed the FAC on March 20, 2015, alleging
    two counts: (1) that all of the Defendants violated section 10(b)
    of the Securities Exchange Act of 1934 (the "Exchange Act"), see
    15 U.S.C. § 78j(b), and Securities and Exchange Commission ("SEC")
    Rule 10b-5, see 17 C.F.R. § 240.10b-5, and (2) that Garabedian and
    Kaye violated section 20(a) of the Exchange Act.     In broad terms,
    the Plaintiffs alleged that the Defendants, in discussing their
    intention to file an NDA in 2014, fraudulently misrepresented the
    FDA's communications to them concerning Sarepta's dystrophin data.
    1  We note that, while we have made reference to these facts, which
    were not before the district court, they do not end up having the
    effect of impacting our analysis.
    -13-
    The Defendants moved to dismiss the FAC for failure to
    state a claim.       See Fed. R. Civ. P. 12(b)(6).         The district court
    granted that motion on April 5, 2016.               It concluded that the FAC
    did   not   allege    "sufficient    facts     to    plausibly   suggest    that
    Defendants made affirmatively misleading statements, or that they
    omitted . . . information needed to make their statements not
    misleading."      It also held that the FAC similarly lacked facts
    supporting an inference of scienter on the part of Sarepta's
    executives as to the allegedly misleading nature of any of their
    statements or omissions.
    The Plaintiffs then filed a motion for leave to amend
    the FAC, attaching the PSAC to that motion.              The PSAC, unlike the
    FAC, contained allegations involving the Briefing Document.                 The
    Briefing Document, according to the Plaintiffs, demonstrated that
    the FDA had communicated to Sarepta a "plethora of concerns" about
    Sarepta's data before and during the Class Period.               It also, said
    the Plaintiffs, illustrated that the Defendants had misrepresented
    Study 201/202 as "blinded."
    On   January   6,   2017,   the   district    court   denied    the
    Plaintiffs' motion for leave to amend.          Specifically, it held that
    the Plaintiffs had delayed unduly in moving to amend, and that, in
    any event, the PSAC was futile because it also failed to state a
    claim.      The Plaintiffs now appeal the district court's orders
    -14-
    denying them leave to file the PSAC and dismissing their claims
    with prejudice.
    II.    THE DISTRICT COURT PROPERLY DISMISSED THE FAC
    We first take up the Plaintiffs' contention that the
    district court erred in dismissing the FAC for failure to state a
    claim.     Our review of a district court's dismissal under Rule
    12(b)(6) is de novo.        Schaefer v. Indymac Mortg. Servs., 
    731 F.3d 98
    , 103 (1st Cir. 2013).          In determining whether the FAC stated a
    claim upon which relief can be granted, "we accept well-pleaded
    factual    allegations      in    the   complaint      as   true    and   view   all
    reasonable inferences in the plaintiffs' favor."                   ACA Fin. Guar.
    Corp. v. Advest, Inc., 
    512 F.3d 46
    , 58 (1st Cir. 2008).
    A. The relevant law
    To survive a motion to dismiss under Rule 12(b)(6), a
    complaint alleging securities fraud under section 10(b) of the
    Exchange Act and Securities and Exchange Commission Rule 10b–5
    must plead six elements: "(1) a material misrepresentation or
    omission;       (2)   scienter,   or    a   wrongful   state   of    mind;   (3)   a
    connection with the purchase or sale of a security; (4) reliance;
    (5) economic loss; and (6) loss causation."                 
    Id. at 58.
       Only the
    first two elements are at issue here.2
    2  While the Plaintiffs also brought claims under section 20(a),
    those claims are "derivative of 10b-5 claims." Hill v. Gozani,

    ("PSLRA"),     15    U.S.C.   §   78u-4,    governs   complaints    alleging
    securities    fraud    and    imposes   a   particularity    requirement   on
    pleadings.     With regard to misleading representations, the PSLRA
    requires that complaints "specify each statement alleged to have
    been misleading [and] the reason or reasons why the statement is
    misleading."        
    Id. § 78u-4(b)(1)(B);
    see also Aldridge v. A.T.
    Cross Corp., 
    284 F.3d 72
    , 78 (1st Cir. 2002).               As for scienter,
    the PSLRA requires that complaints "state with particularity facts
    giving rise to a strong inference that the defendant acted with
    the required state of mind."       15 U.S.C. § 78u-4(b)(2)(A) (emphasis
    added).   To satisfy this "rigorous" requirement, Advest, 
    Inc., 512 F.3d at 58
    , a plaintiff must "show either that the defendants
    consciously intended to defraud, or that they acted with a high
    degree of recklessness," 
    Aldridge, 284 F.3d at 82
    (citing Greebel
    v. FTP Software, Inc., 
    194 F.3d 185
    , 198-201 (1st Cir. 1999)).
    Additionally, the Supreme Court has determined that under the
    PSLRA, "an inference of scienter must be more than merely plausible
    or reasonable -- it must be cogent and at least as compelling as
    company has violated a substantive section of the Exchange Act,
    section 20(a) imposes joint and several liability on that company's
    executives unless they "acted in good faith and did not directly
    or indirectly induce the act or acts constituting the violation or
    cause of action." 15 U.S.C. § 78t(a).
    -16-
    any opposing inference of nonfraudulent intent."          Tellabs, Inc.
    v. Makor Issues & Rights, Ltd., 
    551 U.S. 308
    , 314 (2007); see also
    Advest, 
    Inc., 512 F.3d at 59
    ("[W]here there are equally strong
    inferences for and against scienter, Tellabs now awards the draw
    to the plaintiff.").
    B. Material misrepresentations or omissions
    In dismissing the FAC, the district court first held
    that the complaint failed "to plead any facts plausibly suggesting
    that Defendants' statements or omissions were materially false or
    misleading."   On appeal, the Plaintiffs argue that the district
    court was wrong for two reasons:        (1) the FDA's October 30, 2014
    public   statement   supports   the   inference   that   the   Defendants
    "recklessly misrepresented" their ability to file an NDA by the
    end of 2014, and (2) after receiving a request for independent
    review of its dystrophin data in July 2014, and failing to comply
    with that request, the Defendants misled investors by continuing
    to represent that a 2014 NDA submission was possible and by failing
    to disclose that request and the noncompliance with it.          We take
    these arguments in turn.
    1.
    To begin, we disagree with the Plaintiffs that the FDA's
    October 30 public statement suggests that the FDA had previously
    communicated anything to Sarepta (such as, that its data were
    -17-
    inadequate) that would render misleading the Defendants' continued
    representations that a 2014 NDA submission was possible.                                  That
    inference would not be reasonable. Contrary to what the Plaintiffs
    insist, the FDA did not appear to make its October 30 statement
    with the purpose of correcting any prior misrepresentations by
    Sarepta.    Rather, the statement explicitly purported to "address[]
    questions      the    agency      has     received         from    DMD   patients,    their
    families, and others in the community who are concerned about the
    timing of the filing of an NDA for eteplirsen."
    It is true that the statement highlighted that: (1) "[i]n
    its advice to Sarepta, FDA has consistently stated that it would
    be   necessary       to    include      data     in   its     NDA    demonstrating        that
    eteplirsen increases production of . . . dystrophin"; (2) "the
    need for additional data and analyses to support the NDA was
    reinforced     by     an    FDA   inspection          of    the     clinical   site   where
    dystrophin analyses had been conducted"; and (3) after the site
    visit, the FDA had "provided Sarepta with detailed recommendations
    on how to improve these dystrophin analyses, and FDA's most recent
    advice was consistent with the advice provided after the April
    2014 meeting."        But none of this supports the inference that the
    FDA had previously told Sarepta that its data were categorically
    inadequate. And crucially, the statement also recognized Sarepta's
    April   2014    announcement         of    its    "plans      to     submit    an   NDA    for
    -18-
    eteplirsen     by    the   end    of   2014,"     without    objecting    to    it   or
    otherwise characterizing it as misleading or unfounded.                        So, the
    FDA's statement cannot serve as the scaffolding for any reasonable
    inference that the FDA had communicated anything to Sarepta during
    the   Class    Period      that   would    make    the   Defendants'     subsequent
    representations about filing an NDA in 2014 misleading.
    2.
    The Plaintiffs next turn their focus to the July request
    for independent review, which was not itself disclosed as such.
    The Plaintiffs' theory is that once Sarepta received this request,
    it knew it could not reasonably expect to file an NDA until the
    requested independent review was completed, and it knew that it
    was not acceding to the request.            As a result, the Plaintiffs say,
    its continued assertion on the August 7 call that its existing
    dataset could support accelerated approval was misleading.
    To    advance   this     argument,    Plaintiffs    would    have      us
    assume that the July request for independent review was materially
    different in its potential impact on the likelihood of approval
    than was the FDA's April request for further review (which had
    been disclosed to investors).             For purposes of our disposition of
    this appeal, we can make that assumption.                   In so doing, however,
    we cannot avoid observing that it is hardly obvious that the July
    request for independent review was significantly new and that
    -19-
    compliance with it was more mandatory than what had come before.
    Both before and after the July request, it was the case that the
    FDA was saying that further review by someone other than Sarepta
    would affect the chances of approval, which is precisely what
    Sarepta disclosed.
    C. Scienter
    The   Plaintiffs'      pursue    two   lines   of   argumentation
    regarding scienter: (1) that "concealing and avoiding the requests
    for reassessment recklessly risked misleading investors"; and (2)
    that Sarepta's significant motive to mislead investors is an
    indicia of scienter.3
    1.
    Keeping in mind that inferences of scienter under the
    PSLRA must be "at least as compelling as any opposing inference of
    nonfraudulent intent," 
    Tellabs, 551 U.S. at 314
    , we begin with the
    first of Plaintiffs' arguments.           As the district court correctly
    noted, given that it is the only communication that took place
    after the FDA made this request, Garabedian's August 7, 2014 phone
    call with investors is the only communication we need to look at.4
    3  The Plaintiffs also argue that Garabedian's evasive response to
    a question during his May 7 conference call indicated that he was
    knowingly misleading investors regarding the FDA's July request
    for independent review. But this cannot be right, because according
    to the Plaintiffs, the FDA had not yet made that request.
    4   In   their   reply   brief,   the     Plaintiffs   argue   that   various
    -20-
    In analyzing that call, we also keep in mind our recognition that
    providing warnings to investors, or otherwise disclosing potential
    risks, erodes inferences of scienter.         See Fire & Police Pension
    Ass'n of Colo. v. Abiomed, Inc., 
    778 F.3d 228
    , 244 (1st Cir. 2015)
    (holding that defendants' informative disclosures "undercut any
    inference of scienter"); City of Dearborn Heights Act 345 Police
    & Fire Ret. Sys. v. Walters Corp., 
    632 F.3d 751
    , 760 (1st Cir.
    2011) ("[A]ttempts to provide investors with warnings of risks
    generally    weaken   the   inference   of   scienter."   (alteration   in
    original) (quoting Ezra Charitable Tr. v. Tyco Int'l, Ltd., 
    466 F.3d 1
    , 8 (1st Cir. 2006))).
    The substance of what Garabedian communicated during the
    August 7 phone call severely weakens any inference of scienter.
    He told investors "[a]s a reminder, the FDA indicated in its April
    guidance that if, after further detailed review, they were to find
    the currently available . . . data to be adequate, our existing
    dystrophin data set would have the potential to support accelerated
    approval."     He further explained that Sarepta was "continu[ing]
    to work with the FDA to provide greater assurance of the quality
    statements by the Defendants in April and May of 2014 were
    misleading in light of the FDA's July request for independent
    review. But, this argument necessarily fails because, according to
    the FAC, these phone calls took place before the FDA communicated
    that request to Sarepta.
    -21-
    and   reliability    of   our   dystrophin    data."      In    this    manner,
    Garabedian reminded investors that the FDA was looking for further
    review, as Sarepta disclosed in April. At the same time, Garabedian
    gave no assurance that Sarepta would accede to the type of review
    that the FDA sought.      As we have discussed, the difference between
    those statements and what exactly happened is not obvious, as
    investors knew that Sarepta's chances would be less if it did not
    receive a further review.         And even accepting the Plaintiffs'
    position that there was a material difference nonetheless, it was
    not such that one might reasonably infer scienter from Sarepta's
    failure to elaborate more fully on any difference between a review
    by the FDA and a review for the FDA by another lab.                    In other
    words,   an    arguable   misrepresentation    provides    by    itself    less
    support for an inference of scienter than does a clear falsehood.
    See Flannery v. SEC, 
    810 F.3d 1
    , 9 (1st Cir. 2015) ("If it is
    questionable whether a fact is material or its materiality is
    marginal, that tends to undercut the argument that defendants acted
    with the requisite intent or extreme recklessness in not disclosing
    the fact." (quoting City of Dearborn 
    Heights, 632 F.3d at 757
    )).
    We now turn to the Plaintiffs' related argument that
    Garabedian recklessly risked misleading investors about Sarepta's
    likelihood of achieving that result by failing to mention that
    Sarepta was not complying with the FDA's request for independent
    -22-
    review.   As we have noted, unlike in its October 2014 guidance,
    the FDA did not describe compliance with its July 29, 2014 request
    as a mandatory prerequisite for a successful NDA filing.               And as
    we have previously held, when defendants do not divulge the details
    of interim "regulatory back-and-forth" with the FDA, that alone
    cannot support an inference of scienter under the PSLRA when the
    defendants do provide warnings in broader terms.           See Abiomed,
    
    Inc., 778 F.3d at 243-44
    .      "There must be some room for give and
    take between a regulated entity and its regulator."             
    Id. at 244;
    see also 
    Corban, 868 F.3d at 40
    ("The defendants had no legal
    obligation   to   loop   the   public    into   each   detail     of    every
    communication with the FDA.").
    Additionally, we understand the Plaintiffs' arguments
    about Sarepta's failure to obtain independent review to assert
    that Sarepta was avoiding doing so out of concern that its data
    would not hold up under scrutiny.5        Thus, the argument that the
    Defendants needed to disclose that they had not followed this
    request is a variation on the Plaintiffs' other arguments that the
    Defendants were not forthcoming about the FDA's concerns about
    5  The Plaintiffs do not, for example, argue that Sarepta avoided
    complying with this request because it would be costly, or time
    consuming, or for any other reason unrelated to the risk that
    independent experts would not be able to confirm the studies'
    results.
    -23-
    their data's reliability or that they misleadingly claimed that
    they had strong data.      And we note again that Garabedian admitted
    during the August 7 phone call that the FDA had such concerns about
    Sarepta's    data.        So,    even    if     Garabedian   made     material
    misrepresentations or omissions regarding the July request for
    independent review or Sarepta's compliance with it, the inference
    that he did so with scienter is not sufficiently compelling under
    Tellabs for purposes of stating a claim for securities fraud.
    2.
    The Defendants' purported motive to deceive investors
    similarly    fails   to   make   an   inference    of   scienter    adequately
    compelling. Pointing to Sarepta's public offering during the Class
    Period, the Plaintiffs insist that "[i]n a race for FDA approval
    and generating no significant revenue, Sarepta was dependent upon
    offerings to fund its operations; reporting positive news was
    critical to Sarepta's existence."              We have set a high bar for
    arguments of this sort.           Indeed, "catch-all allegations that
    defendants stood to benefit from wrongdoing" are not enough.
    
    Greebel, 194 F.3d at 197
    (quoting In re Advanta Corp. Sec. Litig.,
    
    180 F.3d 525
    , 535 (3d Cir. 1999)).           Rather, "[w]e require something
    more than the ever-present desire to improve results, such as
    allegations that 'the very survival of the company w[as] on the
    line.'"     
    Corban 868 F.3d at 41
    (second alteration in original)
    -24-
    (quoting In re Cabletron Sys. Inc., 
    311 F.3d 11
    , 39 (1st Cir.
    2002)).
    The Plaintiffs do not clear this bar.        The FAC is bereft
    of allegations that Sarepta was financially on the ropes, or that
    it "would shutter its doors unless it padded earnings by deceiving
    investors."      
    Corban, 868 F.3d at 42
    .         It may be so that this
    offering generated revenue that proved useful to Sarepta in its
    "race for FDA approval," so to secure the "first-mover advantage."
    Yet, that alone cannot bear the weight of an inference of scienter
    that is "at least as compelling" as any other.           
    Tellabs, 551 U.S. at 314
    .
    Therefore, because the Plaintiffs did not adequately
    plead scienter in the FAC, we hold that district court did not err
    in dismissing the FAC for failure to state a claim.
    III.    THE DISTRICT COURT PROPERLY DENIED LEAVE TO AMEND
    We   now   turn   to   the   Plaintiffs'   arguments   that   the
    district court should have granted them leave under Fed. R. Civ.
    P. 15(a) to file the PSAC.         The district court denied leave on the
    grounds that the Plaintiffs had moved to amend with "undue delay"
    and because, in any event, the PSAC also failed to state a claim.
    On appeal, the Plaintiffs urge the opposite: that they did not
    delay unduly and that the PSAC did state a claim.                  We assume
    (without deciding) that the PSAC was not futile, but nonetheless
    -25-
    affirm the district court's denial of leave to amend on undue delay
    grounds.
    Under Fed. R. Civ. P. 15(a)(2), a party may amend a
    pleading "with the court's leave."            The Rule further provides that
    "[t]he court should freely give leave when justice so requires."
    Nonetheless, grounds for denying leave include "undue delay, bad
    faith    or    dilatory   motive   .    .     .   repeated   failure   to   cure
    deficiencies by amendments previously allowed, undue prejudice to
    the opposing party . . . [and] futility of amendment."                 Advest,
    
    Inc., 512 F.3d at 55-56
    (quoting Forman v. Davis, 
    371 U.S. 178
    ,
    182 (1962)).       While "[t]he rule reflects a liberal amendment
    policy . . . the district court enjoys significant latitude in
    deciding whether to grant leave to amend."               
    Id. at 55
    (citation
    omitted).      And notably, "undue delay in moving to amend, even
    standing alone," can provide a court with adequate grounds to deny
    leave.     Zullo v. Lombardo (In re Lombardo), 
    755 F.3d 1
    , 3 (1st
    Cir. 2014).
    We have previously made the observation that "the longer
    a plaintiff delays, the more likely [a] motion to amend will be
    denied."      Advest, 
    Inc., 512 F.3d at 57
    (citing Steir v. Girl Scouts
    of the USA, 
    383 F.3d 7
    , 12 (1st Cir. 2004)).                     And we have
    explicitly condemned a "wait and see" approach to pleading, whereby
    plaintiffs "having the needed information, deliberately wait in
    -26-
    the wings . . . with another amendment to a complaint should the
    court hold the first amended complaint was insufficient."                  
    Id. The Plaintiffs
    filed the FAC on March 20, 2015.                     The
    Briefing Document -- the source of the Plaintiffs' new allegations
    in the PSAC -- became available in January 2016.                   The district
    court denied the FAC on April 5, 2016.                 Three days later, the
    Plaintiffs moved to file the PSAC.
    The PSAC differed from the FAC in two key respects.
    First, it alleged that the FDA had requested an independent review
    of Sarepta's dystrophin data in July 2013 (a year earlier than the
    FAC claimed that this occurred).          Second, it alleged that Sarepta
    had manipulated its dystrophin studies, and that the FDA had
    communicated concerns to Sarepta that "the blinded nature of the
    dystrophin     study   had   been     improperly       broken   after   initial
    (blinded) analysis failed to yield positive results."                        Thus,
    according to the PSAC, the Defendants "misrepresented that the
    dystrophin    analysis   was   conducted     in    a   properly    blinded       and
    controlled     manner,   and       they   misrepresented,         omitted,       and
    recklessly ignored the FDA's repeated guidance to seek independent
    laboratory verification of the dystrophin assessment results."
    Highlighting    the    three-month    gap    between    the     FDA's
    publication of the Briefing Document and the Plaintiffs' motion to
    amend, the district court reasoned that "[t]he timing of the filing
    -27-
    of the motion to amend suggests that rather than moving promptly
    for   leave    to    file   a   new   complaint    based   on   new   information
    discovered in January 2016, the Plaintiffs instead waited for the
    Court's ruling on the Motion to Dismiss before seeking leave to
    amend."    This, it concluded, amounted to "wait and see" pleading,
    and thus undue delay.
    The district court did not abuse its discretion in
    reaching      this   conclusion.       The     Plaintiffs'   arguments    to   the
    contrary focus on their subjective belief in the strength of the
    FAC and on minimizing the three months during which they could
    have moved for leave to amend.           We are unmoved by the Plaintiffs'
    arguments concerning their belief that the FAC adequately stated
    a claim. Regardless of whether or not they intentionally sandbagged
    their claims, the fact remains that despite having three months to
    do so, the Plaintiffs did not move to amend until after the
    district court dismissed the FAC.                  And while the Plaintiffs
    characterize this period of time as "relatively short," we have
    previously upheld denials of leave to amend on undue delay grounds
    after a comparable amount of time.                 See Villanueva v. United
    States, 
    662 F.3d 124
    , 127 (1st Cir. 2011) (affirming a finding of
    undue delay where the plaintiff moved to amend four months after
    filing his complaint); Kaye v. New Hampshire, 
    821 F.2d 31
    , 34 (1st
    -28-
    Cir. 1987) (per curiam) (finding a three-month delay to be a
    sufficient basis for denying leave to amend).
    We also reject the Plaintiffs' argument that moving to
    amend post-dismissal is desirable from the perspective of judicial
    economy.    They press that "it would have been neither practical
    nor economical to move to amend the complaint each time new
    relevant information was released while dispositive motions were
    pending in this case . . . especially in the context of [the]
    dynamic    factual       developments     surrounding    the     [FDA    approval]
    process."       But the Plaintiffs "have it exactly backwards -- their
    methodology      would    lead   to   delays,    inefficiencies,        and   wasted
    work."     Advest, 
    Inc., 512 F.3d at 57
    .                Indeed, the resulting
    "unnecessary costs and inefficiencies on both the courts and party
    opponents" is precisely the reason why we refused to sanction a
    "wait and see" approach to pleading in Advest.                 
    Id. It may
    be so
    that the Plaintiffs did not move to amend at an earlier juncture
    because they believed that further information relevant to their
    claims    may    have    been    coming   down   the    pike    amid    the   FDA's
    consideration of the eteplirsen NDA.             But that is not so much an
    argument against the district court's denial of their motion for
    leave to amend as it is a suggestion that the Plaintiffs perhaps
    jumped the gun in filing the FAC.              Accordingly, we conclude that
    -29-
    the district court did not abuse its discretion in denying leave
    to amend on undue delay grounds.6
    IV.   CONCLUSION
    The FAC failed to state a claim, and even assuming that
    the PSAC did not also suffer from that deficiency, the district
    court did not abuse its discretion in ruling that the Plaintiffs
    moved to file it with undue delay.     Therefore, the district court's
    judgment is affirmed.
    Affirmed.
    6  While both of the PSAC's new claims -- that the FDA had requested
    independent review in July 2013 and that Sarepta had fraudulently
    characterized its dystrophin studies as blinded -- derived from
    the Briefing Document, the PSAC also cited the transcript from the
