    OPINION OF THE COURT
    _______________
    BIBAS, Circuit Judge.
    Statutory silences, like awkward silences, tempt speech.
    But courts must resist the urge to fill in words that Congress
    left out. The Department of Health and Human Services claims
    that drug makers must deliver certain discounted drugs wher-
    ever and to whomever a buyer demands. But the relevant law
    says nothing about such duties. So HHS’s efforts to enforce its
    interpretation against the drug makers here are unlawful.
    I. BACKGROUND
    A. Congress enacted Section 340B
    The federal government dominates the healthcare market.
    Through Medicare and Medicaid, it pays for almost half the
    annual nationwide spending on prescription drugs. See Cong.
    Budget Off., Prescription Drugs: Spending, Use, and Prices 8
    (2022). It uses that market power to get drug makers to subsi-
    dize healthcare. Under Section 340B, drug makers that want to
    take part in Medicare or Medicaid must offer their drugs at a
    discount to certain healthcare providers. 42 U.S.C. §§ 256b,
    1396r-8(a)(1), (5). These providers, called “covered entities,”
    typically care for low-income and rural persons. Section 340B
    helps providers do that. First, it gives them extra revenue from
    serving insured patients: they turn a profit when insurance
    companies reimburse them at full price for drugs that they
    bought at the 340B discount. Second, it enables them to give
    5
    uninsured patients drugs at little or no cost. See Gov’t Account-
    ability Off., Drug Pricing: Manufacturer Discounts in the
    340B Program Offer Benefits, but Federal Oversight Needs
    Improvement 17–18 (GAO-11-836, Sept. 2011).
    Congress enacted Section 340B as part of the Veterans
    Health Care Act of 1992 and amended it in 2010 as part of the
    Affordable Care Act. 
    Pub. L. No. 102-585, § 602
    , 
    106 Stat. 4943
    , 4967; 
    Pub. L. No. 111-148,
     tit. VII.B, §§ 7101–02, 
    124 Stat. 119
    , 821–27 (both codified at 42 U.S.C. § 256b).
    It has three basic parts: (1) a cap on drug makers’ prices,
    (2) restrictions on covered entities, and (3) compliance mech-
    anisms.
    1. Price cap on drug makers. Central to this appeal are two
    provisions requiring drug makers to sell their drugs at or below
    a price cap. First, Section 340B directs the Secretary of HHS
    to sign an agreement with each drug maker capping prices “for
    covered outpatient drugs … purchased by a covered entity.” 42
    U.S.C. § 256b(a)(1). This is known as the “purchased by” re-
    quirement. The second requirement is the “shall offer” provision:
    Each such agreement … shall require that the manufac-
    turer offer each covered entity covered outpatient drugs
    for purchase at or below the applicable ceiling price if
    such drug is made available to any other purchaser at
    any price.
    Id.
    2. Covered-entity restrictions. Section 340B also subjects
    participating covered entities to two restrictions. First, it bans
    duplicate discounts: covered entities cannot get the 340B
    6
    discount on drugs already subject to a Medicaid rebate.
    § 256b(a)(5)(A)(i). Second, it bans diversion: covered entities
    can sell 340B drugs to only their own patients. § 256b(a)(5)(B).
    3. Compliance mechanisms. Though Section 340B’s sub-
    stantive requirements and restrictions are few, its compliance
    provisions are many. See, e.g., § 256b(d). For instance, drug
    makers and the Secretary of HHS can audit covered entities.
    § 256b(a)(5)(C). And the statute specifies punishments for vi-
    olators: drug makers and covered entities can be fined, and
    covered entities can be kicked out of the program.
    § 256b(d)(1)(B)(vi), (d)(2)(B)(v)(I)–(II).
    B. HHS issued guidance on contract pharmacies
    When Congress first enacted Section 340B, few covered
    entities had pharmacies in house. So covered entities sought to
    contract with outside pharmacies to distribute 340B drugs for
    them. Covered entities using contract pharmacies would still
    order and pay for the drugs, but they would be shipped directly
    to the pharmacies. In 1996, HHS issued guidance saying that
    covered entities could use one contract pharmacy each. 
    61 Fed. Reg. 43,549
     (Aug. 23, 1996). Then, in 2010, HHS issued new
    guidance, saying that covered entities could use an unlimited
    number of contract pharmacies. 
    75 Fed. Reg. 10,272
     (Mar. 5,
    2010).
    After the 2010 guidance, the use of contract pharmacies
    skyrocketed. Their number increased twentyfold.
    C. Drug makers rebelled
    This explosion worried drug makers. They thought that
    contract pharmacies were driving up duplicate discounting and
    7
    diversion. So, in 2020, they responded, adopting policies to
    limit the use of contract pharmacies. Here is a summary of the
    three drug makers’ policies at issue:
    2020 Distribution Policy
    1. Covered entities may use an in-house
    pharmacy.
    2. If they do not have an in-house pharmacy,
    Sanofi         they may use one contract pharmacy.
    3. If they agree to provide claims data, they
    may use an unlimited number of contract
    pharmacies.
    1. Covered entities may use an in-house
    pharmacy.
    Novo        2. If they do not have an in-house pharmacy,
    Nordisk         they may use one contract pharmacy.
    3. They may use multiple contract pharma-
    cies at Novo Nordisk’s discretion.
    1. Covered entities may use an in-house
    Astra-         pharmacy.
    Zeneca      2. If they do not have an in-house pharmacy,
    they may use one contract pharmacy.
    D. HHS reacted
    HHS responded with the three actions at the center of this
    litigation.
    1. The Advisory Opinion. First, in December 2020, HHS
    released an Advisory Opinion declaring that Section 340B
    8
    unambiguously requires drug makers to deliver 340B drugs to
    an unlimited number of contract pharmacies. HHS Off. Gen.
    Couns., Advisory Opinion 20-06 on Contract Pharmacies Un-
    der the 340B Program (Dec. 30, 2020), https://perma.cc
    /L7W2-H597. HHS reasoned that 340B drugs are “purchased
    by” a covered entity no matter how they are distributed. 
    Id.
     at 1–
    3. So, it argued, the “situs of delivery … is irrelevant.” 
    Id. at 3
    .
    2. Violation Letters. Five months later, HHS sent Violation
    Letters to the drug makers. These letters said their policies
    were unlawful and ordered them to rescind those policies and
    reimburse covered entities for any overcharges.
    Though the Advisory Opinion relied mainly on Sec-
    tion 340B’s “purchased by” language, the Violation Letters re-
    lied solely on Section 340B’s “shall offer” language. But their
    conclusions were the same: drug makers must deliver dis-
    counted drugs to an unlimited number of contract pharmacies.
    3. The Administrative Dispute Resolution Rule. When
    Congress amended Section 340B back in 2010, it told HHS to
    set up a process through which drug makers and covered enti-
    ties could resolve Section 340B–related disputes. § 256b(d)(3).
    But HHS dawdled. It did not issue a notice of proposed rule-
    making until 2016. 
    81 Fed. Reg. 53,381
     (Aug. 12, 2016). And
    after accepting comments on the proposed Administrative Dis-
    pute Resolution (ADR) Rule, HHS seemed to abandon it. In
    2017, in a regulatory publication called the Unified Agenda, it
    listed the proposed rule as withdrawn. 340B Drug Pricing Pro-
    gram; Administrative Dispute Resolution Process, RIN 0906-
    AA90 (Spring 2017), https://perma.cc/ADX3-QUEJ (noting
    “NPRM Withdrawn” on “08/01/2017”).
    9
    But that would not be the last of the proposed rule. In 2020,
    HHS revived it. The agency said that it had just “paus[ed] ac-
    tion on the proposed rule” rather than withdrawing it. 
    85 Fed. Reg. 80,632
    , 80,633 (Dec. 14, 2020). It then responded to the
    four-year-old comments and issued a final ADR Rule. 
    Id. at 80
    ,633–42, 80,644–46.
    After we heard this appeal, HHS proposed a new rule to
    revise the 2020 ADR Rule’s procedures. 
    87 Fed. Reg. 73,516
    (Nov. 30, 2022). But for now, the 2020 Rule remains in force.
    E. Procedural history
    1. AstraZeneca won in Delaware. Not long after the Advi-
    sory Opinion was issued, AstraZeneca sued in the District of
    Delaware to invalidate it. That Court held that the Advisory
    Opinion was arbitrary and capricious because it wrongly called
    Section 340B unambiguous. AstraZeneca Pharms. LP v.
    Becerra, 
    543 F. Supp. 3d 47
    , 58–62 (D. Del. 2021). Unsure of
    “the precise relief to be granted,” the Court asked for the par-
    ties’ views. 
    Id. at 62
    . Instead, HHS rescinded the Advisory
    Opinion. Finding that rescission did not moot the issue, the
    Court vacated the Advisory Opinion. AstraZeneca Pharms. LP
    v. Becerra, 
    2021 U.S. Dist. LEXIS 122049
    , at *3–5 (D. Del.
    June 30, 2021).
    During the lawsuit, HHS also sent AstraZeneca a Violation
    Letter, ordering it to stop restricting delivery to contract phar-
    macies. AstraZeneca Pharms. LP v. Becerra, 
    2022 WL 484587
    , at *3 (D. Del. Feb. 16, 2022). The Court likewise va-
    cated the Violation Letter because it rested on the same flawed
    premise that Section 340B was unambiguous and wrongly
    10
    called HHS’s position consistent between 1996 and 2010. 
    Id.
    at *5–6, 9.
    2. But the government won in New Jersey. Things played
    out differently for Sanofi and Novo Nordisk in the District of
    New Jersey. That Court held that their challenge to the Advi-
    sory Opinion was moot. Sanofi-Aventis U.S., LLC v. HHS, 
    570 F. Supp. 3d 129
    , 159 n.31 (D.N.J. 2021). And although it
    agreed with the District of Delaware that Section 340B was
    ambiguous, it mostly upheld the Violation Letters. Relying
    largely on the statute’s purpose and legislative history, it con-
    cluded that Section 340B requires delivery to at least one con-
    tract pharmacy. 
    Id.
     at 193–202. Yet rather than decide whether
    it also requires delivery to an unlimited number of contract
    pharmacies, the Court remanded to the agency for further con-
    sideration. 
    Id.
     at 203–06. Finally, it upheld the ADR Rule, re-
    jecting a challenge to the agency’s notice-and-comment pro-
    cess. 
    Id.
     at 161–67.
    A flurry of appeals from both District Court proceedings is
    now before us. From the District of Delaware, HHS has ap-
    pealed. From the District of New Jersey, Sanofi and Novo
    Nordisk have appealed and HHS has cross-appealed.
    We review the District Courts’ rulings de novo. See Eid v.
    
    Thompson, 740
     F.3d 118, 122 (3d Cir. 2014). And we review
    the underlying agency actions for whether they were “arbitrary,
    capricious, an abuse of discretion, or otherwise not in accord-
    ance with law.” 
    Id.
     (quoting 
    5 U.S.C. § 706
    (2)(A)).
    11
    II. THE GOVERNMENT MAY NOT ENFORCE ITS READING
    OF THE STATUTE AGAINST THESE DRUG MAKERS
    A. The drug makers’ challenge to the Advisory
    Opinion is not moot
    We start with the government’s half-hearted suggestion that
    the dispute over the Advisory Opinion is moot. It is not.
    Though HHS rescinded the Opinion after it lost in Delaware, it
    has “not altered its position” on the use of contract pharmacies.
    Solar Turbines Inc. v. Seif, 
    879 F.2d 1073
    , 1079 (3d Cir. 1989).
    It still says that drug makers must deliver their drugs to an un-
    limited number of contract pharmacies. And it still takes en-
    forcement actions in line with that view. “We will understand-
    ably be skeptical of a claim of mootness when a defendant
    yields in the face of a court [ruling] and assures us that the case
    is moot because the injury will not recur, yet maintains that its
    conduct was lawful all along.” Hartnett v. Pa. State Educ. Ass’n,
    
    963 F.3d 301
    , 306 (3d Cir. 2020). That is what happened here.
    True, by rescinding the Advisory Opinion, HHS obviated
    vacating it. Cf. United States v. Texas, No. 22-58 (U.S. argued
    Nov. 29, 2022) (considering vacatur as a remedy under the
    APA). But we can still enjoin HHS from reverting to the Ad-
    visory Opinion’s interpretation of Section 340B. United States
    v. W. T. Grant Co., 
    345 U.S. 629
    , 633 (1953) (“[T]he court’s
    power to grant injunctive relief survives discontinuance of the
    illegal conduct.”). Thus, the dispute is not moot.
    12
    B. Section 340B does not require delivery to an
    unlimited number of contract pharmacies
    Both the Advisory Opinion and the Violation Letters say
    Section 340B requires drug makers to deliver drugs to an un-
    limited number of contract pharmacies. As the parties agree,
    HHS lacks rulemaking authority here, so its reading does not
    merit Chevron deference. See Christensen v. Harris Cnty., 
    529 U.S. 576
    , 587 (2000). Nor does it merit Skidmore deference.
    The agency’s reading is “entitled to respect …, but only to the
    extent that” it has “the power to persuade.” 
    Id.
     (internal quota-
    tion marks omitted). As we explain below, “we find unpersua-
    sive the agency’s interpretation of the statute.” 
    Id.
     So it de-
    serves no deference.
    1. The text is silent about delivery. We turn to the statutory
    text. The parties focus on Section 340B’s “shall offer” provi-
    sion. If drug makers make drugs available to anyone at any
    price, they must “offer” those drugs to “covered entities” at a
    discount. 42 U.S.C. § 256b(a)(1). Nowhere does Section 340B
    mention contract pharmacies.
    Nor does the word “offer” imply that the offeror must de-
    liver goods wherever and to whomever the buyer demands.
    “Offer” means to “present[ ] something for acceptance.” Offer,
    Black’s Law Dictionary (11th ed. 2019). Even if drug makers
    limit where they will deliver drugs, they still present the drugs
    for covered entities’ acceptance. And the drug makers’ deliv-
    ery conditions do not prevent any covered entity from accept-
    ing these offers. Each can still buy and dispense unlimited dis-
    counted drugs by having them delivered to an in-house or con-
    tract pharmacy.
    13
    By contrast, one could argue that if a drug maker barred all
    use of contract pharmacies, it would not “present” discounted
    drugs “for acceptance” by all covered entities. A covered entity
    that lacks an in-house pharmacy and cannot use a contract
    pharmacy might have no way to dispense the drugs and so
    could not in practice “accept” them. But that situation is not
    before us. Under the three drug makers’ policies at issue, all
    covered entities can still use the Section 340B program.
    Though the covered entities cannot squeeze as much revenue
    out of it as they once could, drug makers need not help them
    maximize their 340B profits.
    Section 340B’s “purchased by” language likewise says
    nothing about delivery. § 256b(a)(1). HHS reasoned that be-
    cause discounted drugs are “purchased by” a covered entity no
    matter where they are delivered, drug makers must deliver
    them wherever a covered entity demands, whether that be “a
    neighborhood pharmacy” or “the lunar surface.” HHS Off.
    Gen. Couns., Advisory Opinion 2–3. But that is one giant leap
    from the text. The “purchased by” provision imposes only a
    price term for drug sales to covered entities, leaving all other
    terms blank. See § 256b(a)(1). HHS suggests that covered enti-
    ties get to fill in those blanks so long as they foot the bill. But
    when Congress’s words run out, covered entities may not pick
    up the pen. Plus, Congress’s use of the singular “covered en-
    tity” in the “purchased by” language suggests that it had in
    mind one-to-one transactions between a covered entity and a
    drug maker without mixing in a plethora of pharmacies.
    No other language in Section 340B requires delivery to an
    unlimited number of contract pharmacies. Still, HHS says that
    the drug makers’ policies are “not permit[ted]” just because
    14
    Section 340B does not “expressly prohibit[ ]” them. HHS Resp.
    Br. 33 (internal quotation marks omitted). But that logic is “ex-
    actly backwards.” Christensen, 
    529 U.S. at 588
    . Unless Section
    340B “prohibits” drug makers from adopting their policies,
    HHS cannot show that they have violated Section 340B. 
    Id.
    (emphasis in original). Because Section 340B “contains no
    such prohibition,” the drug makers’ policies are lawful. Id.
    2. Structural clues confirm that the statute does not require
    unlimited delivery. Several structural clues confirm our reading
    of Section 340B. To start, “Congress knew how to” grant cov-
    ered entities permission to contract with third parties for distri-
    bution. State Farm Fire & Cas. Co. v. United States ex rel.
    Rigsby, 
    580 U.S. 26
    , 36 (2016); Rotkiske v. Klemm, 
    140 S. Ct. 355
    , 361 (2019). A subsection elsewhere in Section 340B in-
    structs HHS to set up a program under which “covered entities
    may enter into contracts with prime vendors for the distribution
    of covered outpatient drugs.” § 256b(a)(8). Congress could
    have included similar language for contract pharmacies but did
    not.
    Congress also knew how to impose delivery-related re-
    quirements. That same subsection provides that if covered en-
    tities “obtain[ ] drugs directly from a manufacturer, the manu-
    facturer shall be responsible for the costs of distribution.” Id.
    Again, Congress could have similarly required drug makers to
    deliver their drugs to certain places. And again, it chose not to.
    What is more, Section 340B’s statutory neighbor includes
    language along the lines of what the government asks us to in-
    sert into Section 340B. 
    Pub. L. No. 102-585, § 603
    (a)(1), 
    106 Stat. 4943
    , 4971 (codified at 
    38 U.S.C. § 8126
    ). That

    neighboring provision was enacted as part of the same Veter-
    ans Health Care Act of 1992, and it started on the very page of
    the Act where Section 340B ended. It regulates the prices that
    federal agencies pay for drugs. Like Section 340B, it directs
    the Secretary of HHS to enter agreements with drug makers to
    sell “covered drug[s]” at discounted prices. 
    38 U.S.C. § 8126
    (a)(2). But unlike Section 340B, it expressly contem-
    plates drug makers selling discounted drugs through contract
    pharmacies. 
    Id.
     § 8126(a)(2), (h)(3)(A)(ii). Discounts apply to
    drugs “purchased under depot contracting systems,” including
    those delivered through “a commercial entity operating under
    contract with [the] agency.” Id. Congress added that specific
    language there but not here. We presume that it did so inten-
    tionally. Barnhart v. Sigmon Coal Co., 
    534 U.S. 438
    , 452
    (2002).
    The government’s reading would also put drug makers in a
    legal bind. Some drugs are so risky that the Food and Drug
    Administration requires drug makers to develop programs for
    their safe use. See, e.g., 
    21 U.S.C. § 355-1
    . Drug makers often
    comply by limiting distribution to a few pharmacies that are
    specially trained to educate and monitor patients. The govern-
    ment now says that such limits are illegal under Section 340B.
    Perhaps there is a costly, complex way to comply with both
    requirements, but this tension is another strike against the gov-
    ernment’s reading. Leaving drug makers discretion on delivery
    is not only more consistent with Section 340B’s text, but also
    more consistent with this other statutory requirement.
    Finally, Section 340B’s compliance measures do not im-
    plicitly preclude delivery limits. Recall that the drug makers
    say their restrictions were driven by concerns about contract
    16
    pharmacies’ compliance. In response, the government cor-
    rectly notes that Section 340B already has extensive compli-
    ance measures. See, e.g., § 256b(a)(5)(C)–(D), (d)(2). So, it
    reasons, drug makers may not tack on measures of their own.
    That misses the mark. The statute directs its compliance provi-
    sions at covered entities, not contract pharmacies. For instance,
    it authorizes audits of only “covered entit[ies].” See
    § 256b(a)(5)(C). So the government’s inference that drug mak-
    ers cannot limit the use of contract pharmacies “go[es] beyond
    the category to which the negative implication pertains.” An-
    tonin Scalia & Bryan A. Garner, Reading Law 108 (2012)
    (negative-implication canon). In short, the statutory structure
    supports the drug makers, not the government.
    3. Neither drafting history nor legislative purpose compels
    a different result. With no textual or structural hook for its po-
    sition, the government grasps at drafting history and legislative
    purpose. Neither calls for a different outcome.
    Take drafting history. When enacting Section 340B, Con-
    gress also considered a bill that would have required discounts
    on drugs “purchased and dispensed by, or under a contract en-
    tered into for on-site pharmacy services with,” a covered entity.
    S. Rep. No. 102-259, at 2 (1992). Section 340B kept the “pur-
    chased by” language but dropped the rest. § 256b(a)(1). So, the
    government reasons, Congress must have meant for drug mak-
    ers to give discounts on all drugs “purchased by” covered enti-
    ties, no matter how they are dispensed.
    But drawing inferences from unenacted drafting history is
    “perilous.” District of Columbia v. Heller, 
    554 U.S. 570
    , 590
    (2008); see Ramos v. Louisiana, 
    140 S. Ct. 1390
    , 1400 (2020).
    17
    Just so here. Congress could have omitted the language about
    on-site pharmacies because it did not want any contract phar-
    macy involved in the 340B program. With that language gone,
    it might have thought that the language letting a covered entity
    dispense 340B drugs was unnecessary: of course covered enti-
    ties are allowed to dispense drugs that they buy. In other words,
    the same cutting-room scrap can support “opposite infer-
    ence[s].” Ramos, 
    140 S. Ct. at 1400
    .
    Finally, the government argues that letting drug makers
    limit the use of contract pharmacies would thwart Congress’s
    purpose in enacting Section 340B. When it was passed, few
    covered entities had in-house pharmacies, so most could not
    have accessed the discounted drugs without contract pharma-
    cies. But this argument does not get the government where it
    needs to go. Congress might have expected that a covered en-
    tity without its own in-house pharmacy could instead use one
    contract pharmacy. But that is a far cry from the government’s
    current position that covered entities may use an unlimited
    number of contract pharmacies.
    So the Violation Letters and Advisory Opinion are unlaw-
    ful. These three drug makers’ restrictions on delivery to con-
    tract pharmacies do not violate Section 340B. And we will en-
    join HHS from enforcing against them its reading of Section
    340B as requiring delivery of discounted drugs to an unlimited
    number of contract pharmacies. That will give them complete
    relief. We conclude by considering the ADR Rule.
    III. THE ADR RULE IS LAWFUL
    Only Sanofi challenges the ADR Rule. It says the Rule vi-
    olated the APA’s notice and comment requirements because it
    18
    rested on a proposed rule that, in a 2017 publication, HHS
    listed as withdrawn. The government responds that it never
    withdrew the rule, but just “paus[ed] action on” it. 85 Fed. Reg.
    at 80,633.
    The APA does not mention withdrawing proposed rules.
    Nor has the Supreme Court. So we are reluctant to give with-
    drawal separate legal significance under the APA. Rather,
    marking a rule as withdrawn seems to be just a message about
    an agency’s intent.
    Sanofi argues that if an agency later changes its mind, it
    must start over. But nothing in the APA says that. Instead, all
    the APA requires of an agency before publishing a final rule is
    (1) putting a notice of proposed rulemaking in the Federal Reg-
    ister, (2) accepting comments on that proposal, and (3) consid-
    ering those comments. See 
    5 U.S.C. § 553
    (b)–(c). Though HHS
    listed the rule as withdrawn, that did not negate that HHS had
    taken the required steps: the public knew about the proposed
    rule and had a chance to comment on it, and the agency con-
    sidered those comments. The APA prescribes the “maximum
    procedural requirements that an agency must follow in order to
    promulgate a rule.” Little Sisters of the Poor Saints Peter &
    Paul Home v. Pennsylvania, 
    140 S. Ct. 2367
    , 2385 (2020) (in-
    ternal quotation marks omitted). No more was needed.
    Still, Sanofi complains that it was caught off guard by the
    ADR Rule’s promulgation. Our dissenting colleague echoes
    this concern. But the APA already accounts for blindsiding.
    For instance, it requires an agency to publish a final rule thirty
    days before it takes effect. 
    5 U.S.C. § 553
    (d). Again, HHS did
    that. We cannot require something more.
    19
    Even if an agency had the power to effectively nullify the
    prior notice and comments, we think it would require some-
    thing more than what happened here. The proposed rule was
    marked as withdrawn in the Unified Agenda, which is pub-
    lished semiannually by the Office of Information and Regula-
    tory Affairs to lay out the executive branch’s plans. But that
    publication was not created as part of the APA. Instead, its ex-
    press purpose is to “help[ ] agencies comply with their obliga-
    tions” under various other statutes and executive orders. See 
    86 Fed. Reg. 41,166
    , 41,167-68. It would be odd if agencies could
    nullify past steps taken to comply with the APA in a publica-
    tion that has little if anything to do with the APA.
    Plus, the Unified Agenda says it does “not create a legal
    obligation on agencies … to confine their regulatory activities
    to those regulations that appear within it.” See 
    id. at 41,167
    .
    This disclaimer should have put the drug makers on notice that
    the agency was not binding itself simply by listing the rule as
    withdrawn there. And though there was a long delay between
    the notice of proposed rulemaking and finalizing the rule, such
    delays do happen. See, e.g., 
    85 Fed. Reg. 49,240
    , 49,243 (Aug.
    13, 2020) (promulgation nearly five years after notice of pro-
    posed rulemaking); 
    85 Fed. Reg. 13,312
    , 13,314 (Mar. 6, 2020)
    (promulgation nearly four years after notice of proposed rule-
    making). Ultimately, Sanofi’s complaints ring hollow.
    * * * * *
    Legal duties do not spring from silence. Congress never
    said that drug makers must deliver discounted Section 340B
    drugs to an unlimited number of contract pharmacies. So by
    trying to enforce that supposed requirement, the government
    20
    overstepped the statute’s bounds. And HHS did not violate the
    APA by purporting to withdraw the proposed ADR Rule before
    later finalizing it.

    Sanofi Aventis US LCC v. United States HHS, et al.
    Case Nos. 21-3167, 21-3168, 21-3379, 21-3380, 22-1676
    AMBRO, Circuit Judge, dissenting in part.
    I join my colleagues in all but Part III. Because HHS
    took multiple actions alerting the public it had withdrawn its
    notice of proposed rulemaking (“NPRM”) outlining an
    administrative dispute resolution (“ADR”) process, I would
    vacate the final ADR Rule and remand for HHS to issue a new
    NPRM.
    The usual process by which an agency promulgates a
    binding final rule is as follows. It publishes an NPRM in the
    Federal Register that includes “the terms or substance of the
    proposed rule or a description of the subjects and issues
    involved.” 
    5 U.S.C. § 553
    (b)(3). It then allows for comments
    by “giv[ing] interested persons an opportunity to participate in
    the rule making through submission of written data, views, or
    arguments.” 
    Id.
     § 553(c). Finally, and only after considering
    the comments submitted, the agency may publish the final rule.
    Id.
    The process for deciding not to promulgate a final rule
    after it is proposed is less clear. Neither the APA nor the
    Supreme Court has set out procedures for withdrawing an
    NPRM. Usual practice is to publish a notice of withdrawal in
    the Federal Register. See, e.g., 
    83 Fed. Reg. 60,804
     (Nov. 27,
    2018) (HHS withdrawal of proposed rule); 
    84 Fed. Reg. 37,821
    (Aug. 2, 2019) (same). That said, because the APA’s notice-
    1
    and-comment requirements are meant to “ensure fairness to
    affected parties,” Council Tree Commc’ns, Inc. v. F.C.C., 
    619 F.3d 235
    , 250 (3d Cir. 2010) (quoting Int’l Union, United Mine
    Workers v. Mine Safety & Health Admin., 
    407 F.3d 1250
    ,
    1259-60 (D.C. Cir. 2005)), I propose a practical rule: Some
    agency actions short of formal notice in the Federal Register
    should constitute withdrawal because they make any
    reasonable person believe the proposed rule would not take
    effect.
    Here, HHS took multiple actions indicating it had
    withdrawn the NPRM for the ADR process. To start, HHS
    removed it from the Unified Agenda. More specifically, the
    website of the Office of Information and Regulatory Affairs
    (“OIRA”) displays the NPRM as “Withdrawn” as of August 1,
    2017, and identifies the stage of rulemaking as “Completed
    Action,” which is a term used to describe “rulemakings that are
    being [w]ithdrawn or ending their lifecycle with a regulatory
    action that completes the rulemaking.” OIRA, About the
    Unified Agenda, https://bit.ly/2OYh3FZ (last visited Oct. 26,
    2022). Further, in March 2020 an official from the Health
    Resources and Services Administration, an agency within HHS
    that operates the 340B program, stated that it did “not plan to
    move forward on issuing [an ADR] regulation due to the
    challenges with enforcement of guidance.” SJA 788. And
    ultimately, when HHS issued the final ADR Rule in December
    2020, it did so under a new Regulatory Identification Number
    (“RIN”). Compare 
    85 Fed. Reg. 80,632
     (RIN 0906-AB26),
    with 
    81 Fed. Reg. 53,381
     (RIN 0906-AA90). Even if HHS
    thought it paused consideration of the proposed ADR Rule
    temporarily, the agency’s words and actions put the public on
    notice that it withdrew the proposal.
    2
    Any one of these facts alone may not be sufficient to
    constitute a withdrawal of the NPRM. But when an agency
    consistently takes the position for three years that it will not
    turn that proposed rule into a final rule, the public should be
    able to take what the agency says at face value.
    As a result, I respectfully dissent in part. I would vacate
    the final ADR Rule and remand to allow HHS to publish a new
    NPRM, which HHS has done since we heard argument in this
    appeal. See 
    87 Fed. Reg. 73,516
     (Nov. 30, 2022).
