Rhea-AI Filing Summary

On 20 June 2025, Kronos Bio, Inc. (KRON) submitted five Post-Effective Amendment No. 1 filings to its prior Form S-8 registration statements, formally deregistering all remaining unissued shares tied to the company’s employee equity plans. The amendments cover the 2017 Equity Incentive Plan, the 2020 Equity Incentive Plan and the 2020 Employee Stock Purchase Plan, which together had originally registered more than 17 million shares across filings 333-249424, 333-254620, 333-262993, 333-270564 and 333-278125.

The clean-up filing follows the completion of the previously announced merger with Concentra Biosciences. Effective the same day, Concentra Merger Sub IV merged into Kronos, leaving Kronos as a wholly owned subsidiary. Each outstanding KRON common share—except those held in treasury, by the buyer or by dissenting holders—was converted into the right to receive $0.57 in cash plus one non-transferable contingent value right (CVR).

Because the merger terminates any future issuances under the equity plans, Kronos has ended the related securities offerings and removed any unsold securities from registration, satisfying its undertaking under Rule 415. The filing is largely administrative, eliminates potential dilution from unused plan shares and confirms that KRON equity no longer trades publicly.

Il 20 giugno 2025, Kronos Bio, Inc. (KRON) ha presentato cinque Emendamenti Post-Efficacia n. 1 relativi alle precedenti dichiarazioni di registrazione Form S-8, procedendo formalmente alla cancellazione di tutte le azioni non emesse residue associate ai piani azionari per i dipendenti dell’azienda. Gli emendamenti riguardano il Piano di Incentivi Azionari 2017, il Piano di Incentivi Azionari 2020 e il Piano di Acquisto Azioni Dipendenti 2020, che complessivamente avevano registrato più di 17 milioni di azioni nei documenti 333-249424, 333-254620, 333-262993, 333-270564 e 333-278125.

Questa operazione di pulizia segue il completamento della fusione precedentemente annunciata con Concentra Biosciences. Effettiva nello stesso giorno, Concentra Merger Sub IV si è fusa in Kronos, rendendo Kronos una controllata al 100%. Ogni azione ordinaria KRON in circolazione – esclusi quelle in tesoreria, detenute dall’acquirente o dai soci dissenzienti – è stata convertita nel diritto di ricevere 0,57 $ in contanti più un diritto di valore contingente (CVR) non trasferibile.

Poiché la fusione pone fine a qualsiasi futura emissione sotto i piani azionari, Kronos ha chiuso le relative offerte di titoli e rimosso dal registro eventuali titoli invenduti, adempiendo al suo impegno ai sensi della Regola 415. La presentazione è principalmente di natura amministrativa, elimina potenziali diluizioni derivanti da azioni inutilizzate nei piani e conferma che le azioni KRON non sono più negoziate pubblicamente.

El 20 de junio de 2025, Kronos Bio, Inc. (KRON) presentó cinco Enmiendas Post-Efectivas No. 1 a sus declaraciones de registro Form S-8 anteriores, formalmente cancelando todas las acciones no emitidas restantes vinculadas a los planes de acciones para empleados de la empresa. Las enmiendas cubren el Plan de Incentivos de Acciones 2017, el Plan de Incentivos de Acciones 2020 y el Plan de Compra de Acciones para Empleados 2020, que en conjunto habían registrado originalmente más de 17 millones de acciones en los documentos 333-249424, 333-254620, 333-262993, 333-270564 y 333-278125.

Esta limpieza administrativa sigue a la finalización de la fusión previamente anunciada con Concentra Biosciences. Con efecto el mismo día, Concentra Merger Sub IV se fusionó con Kronos, dejando a Kronos como una filial de propiedad total. Cada acción ordinaria KRON en circulación – excepto las mantenidas en tesorería, por el comprador o por los accionistas disidentes – se convirtió en el derecho a recibir $0.57 en efectivo más un derecho contingente de valor (CVR) no transferible.

Dado que la fusión termina cualquier emisión futura bajo los planes de acciones, Kronos ha finalizado las ofertas relacionadas de valores y ha eliminado cualquier valor no vendido del registro, cumpliendo con su compromiso bajo la Regla 415. La presentación es principalmente administrativa, elimina la posible dilución de acciones no utilizadas en los planes y confirma que las acciones KRON ya no se negocian públicamente.

2025년 6월 20일, Kronos Bio, Inc. (KRON)은 이전 Form S-8 등록서류에 대해 다섯 건의 Post-Effective Amendment No. 1을 제출하며 회사 직원 주식 계획과 관련된 남아있는 미발행 주식 전부를 공식적으로 말소했습니다. 이번 수정안은 2017년 주식 인센티브 계획, 2020년 주식 인센티브 계획, 2020년 직원 주식 구매 계획을 포함하며, 이들 계획은 원래 333-249424, 333-254620, 333-262993, 333-270564, 333-278125 문서에 걸쳐 1700만 주 이상를 등록했습니다.

이 정리 제출은 이전에 발표된 Concentra Biosciences와의 합병 완료에 따른 것입니다. 같은 날 효력이 발생하여 Concentra Merger Sub IV가 Kronos에 합병되어 Kronos가 완전 자회사가 되었습니다. 보유 중인 KRON 보통주 중, 자사주, 매수자 보유주, 이의 보유주를 제외한 모든 주식은 주당 현금 0.57달러와 양도 불가능한 조건부 가치 권리(CVR) 1주로 전환되었습니다.

합병으로 인해 앞으로 주식 계획에 따른 추가 발행이 종료됨에 따라 Kronos는 관련 증권 발행을 종료하고 미판매 증권을 등록에서 제거하여 Rule 415에 따른 약속을 이행했습니다. 이번 제출은 주로 행정적 절차이며, 미사용 계획 주식으로 인한 희석 가능성을 제거하고 KRON 주식이 더 이상 공개 시장에서 거래되지 않음을 확인합니다.

Le 20 juin 2025, Kronos Bio, Inc. (KRON) a déposé cinq Amendements Post-Efficaces n° 1 à ses déclarations d’enregistrement Form S-8 antérieures, procédant formellement à la radiation de toutes les actions non émises restantes liées aux plans d’actions des employés de la société. Les amendements couvrent le Plan d’Incitation en Actions 2017, le Plan d’Incitation en Actions 2020 et le Plan d’Achat d’Actions Employés 2020, qui avaient initialement enregistré plus de 17 millions d’actions dans les dépôts 333-249424, 333-254620, 333-262993, 333-270564 et 333-278125.

Cette opération de nettoyage fait suite à la finalisation de la fusion annoncée précédemment avec Concentra Biosciences. Entrée en vigueur le même jour, Concentra Merger Sub IV a fusionné avec Kronos, faisant de Kronos une filiale détenue à 100 %. Chaque action ordinaire KRON en circulation – à l’exception de celles détenues en trésorerie, par l’acheteur ou par les actionnaires dissidents – a été convertie en droit de recevoir 0,57 $ en espèces plus un droit de valeur conditionnel (CVR) non transférable.

Étant donné que la fusion met fin à toute émission future dans le cadre des plans d’actions, Kronos a clôturé les offres de titres associées et retiré les titres invendus de l’enregistrement, respectant ainsi son engagement en vertu de la Règle 415. Le dépôt est principalement administratif, élimine toute dilution potentielle liée aux actions non utilisées dans les plans et confirme que les actions KRON ne sont plus négociées publiquement.

Am 20. Juni 2025 reichte Kronos Bio, Inc. (KRON) fünf Post-Effective Amendment Nr. 1 zu seinen früheren Form S-8-Registrierungserklärungen ein und strich damit formell alle verbleibenden nicht ausgegebenen Aktien, die mit den Mitarbeiterbeteiligungsplänen des Unternehmens verbunden sind. Die Änderungen betreffen den Equity Incentive Plan 2017, den Equity Incentive Plan 2020 und den Employee Stock Purchase Plan 2020, die zusammen ursprünglich mehr als 17 Millionen Aktien in den Einreichungen 333-249424, 333-254620, 333-262993, 333-270564 und 333-278125 registriert hatten.

Die Bereinigung erfolgt nach Abschluss der zuvor angekündigten Fusion mit Concentra Biosciences. Zum selben Tag wurde Concentra Merger Sub IV in Kronos eingegliedert, wodurch Kronos eine vollständig im Besitz stehende Tochtergesellschaft wurde. Jede ausstehende KRON-Stammaktie – außer denen im eigenen Bestand, beim Käufer oder bei abweichenden Aktionären – wurde in das Recht auf 0,57 USD in bar plus ein nicht übertragbares bedingtes Wertrecht (CVR) umgewandelt.

Da die Fusion künftige Ausgaben unter den Aktienplänen beendet, hat Kronos die damit verbundenen Wertpapierangebote eingestellt und nicht verkaufte Wertpapiere aus der Registrierung entfernt, womit die Verpflichtung gemäß Regel 415 erfüllt wurde. Die Einreichung ist größtenteils administrativ, beseitigt potenzielle Verwässerungen durch ungenutzte Planaktien und bestätigt, dass KRON-Aktien nicht mehr öffentlich gehandelt werden.

Positive
  • Completion of the merger provided shareholders with $0.57 cash per share plus a contingent value right.
  • Deregistration of all unsold equity plan shares eliminates any future dilution risk.
Negative
  • KRON is now a privately held subsidiary; public investors no longer have direct access to the company’s equity.

Insights

TL;DR: Housekeeping S-8 POS removes unused plan shares after close of $0.57-per-share takeover; no incremental valuation impact.

All substantive economics of the Concentra transaction were set when the merger agreement was signed on 1 May 2025. Today’s filing merely perfects post-closing mechanics: it terminates the five equity-plan registration statements and deregisters roughly 17 million shares that would otherwise remain on the SEC’s books. By extinguishing any residual issuance authority, the parent eliminates hypothetical dilution and tidies up compliance exposure. Investors already received their cash and CVR; therefore, the amendment does not change consideration or introduce new liabilities. Materiality is minimal and purely procedural.

TL;DR: Filing finalises KRON’s exit from capital markets; equity plans void, shares deregistered, impact neutral for former public holders.

From a securities-law perspective, filings under Rule 478 allow one officer—here the CFO—to sign amendments that terminate the effectiveness of the S-8s. Kronos’ designation as a non-accelerated, smaller reporting company remains irrelevant going forward because it will cease periodic reporting. The CVR structure means upside, if any, lies outside KRON’s former equity; today’s action only confirms no further plan-share supply can hit the market. Consequently the news is operationally neutral and investment-grade portfolios that still carry KRON tickers should already have been redeemed at $0.57. Impact classification: not impactful.
