Rhea-AI Filing Summary

Form 4 overview: On 07/10/2025, director Matthew Winkler reported the automatic disposition of 984,513 Akoya Biosciences (AKYA) common shares on 07/08/2025 under transaction code J. The shares were converted pursuant to the Amended and Restated Agreement and Plan of Merger dated 04/28/2025, whereby Akoya merged with a wholly owned subsidiary of Quanterix Corporation and became its wholly owned subsidiary.

Under the merger terms, each Akoya share was exchanged for 0.1461 Quanterix share plus $0.38 in cash, subject to potential adjustment. Following the closing, Winkler now reports zero AKYA shares beneficially owned.

The filing also discloses the cancellation of 153,731 stock options with strike prices between $2.01 and $21.95 that were at or above the per-share merger consideration; these options were terminated for no consideration.

No open-market trades, pricing data, or new financial metrics are included—this is a procedural disclosure linked solely to the completed merger.

Panoramica del Modulo 4: Il 10/07/2025, il direttore Matthew Winkler ha segnalato la cessione automatica di 984.513 azioni ordinarie di Akoya Biosciences (AKYA) avvenuta il 08/07/2025 con il codice transazione J. Le azioni sono state convertite in base all'Accordo di Fusione Modificato e Rifirmato del 28/04/2025, in cui Akoya si è fusa con una controllata interamente posseduta da Quanterix Corporation diventandone una controllata al 100%.

Secondo i termini della fusione, ogni azione Akoya è stata scambiata con 0,1461 azioni Quanterix più 0,38 $ in contanti, soggetto a possibili aggiustamenti. Dopo la chiusura, Winkler ora dichiara di non possedere più azioni AKYA.

La comunicazione rivela anche la cancellazione di 153.731 opzioni azionarie con prezzi di esercizio tra 2,01 $ e 21,95 $, pari o superiori al valore per azione stabilito dalla fusione; queste opzioni sono state annullate senza alcun compenso.

Non sono inclusi scambi sul mercato aperto, dati sui prezzi o nuove metriche finanziarie: si tratta di una comunicazione procedurale collegata esclusivamente alla fusione completata.

Vue d'ensemble du formulaire 4 : Le 10/07/2025, le directeur Matthew Winkler a déclaré la cession automatique de 984 513 actions ordinaires d'Akoya Biosciences (AKYA) le 08/07/2025 sous le code de transaction J. Les actions ont été converties conformément à l'Accord de fusion modifié et révisé daté du 28/04/2025, par lequel Akoya a fusionné avec une filiale en propriété exclusive de Quanterix Corporation, devenant ainsi une filiale à part entière.

Selon les termes de la fusion, chaque action Akoya a été échangée contre 0,1461 action Quanterix plus 0,38 $ en espèces, sous réserve d'ajustements éventuels. Après la clôture, Winkler déclare désormais ne plus détenir d'actions AKYA.

Le dépôt révèle également l'annulation de 153 731 options d'achat d'actions avec des prix d'exercice compris entre 2,01 $ et 21,95 $, égaux ou supérieurs à la contrepartie par action de la fusion ; ces options ont été résiliées sans contrepartie.

Überblick Formular 4: Am 10.07.2025 meldete Direktor Matthew Winkler die automatische Veräußerung von 984.513 Stammaktien von Akoya Biosciences (AKYA) am 08.07.2025 unter dem Transaktionscode J. Die Aktien wurden gemäß dem geänderten und neu gefassten Fusionsvertrag vom 28.04.2025 umgewandelt, wonach Akoya mit einer hundertprozentigen Tochtergesellschaft der Quanterix Corporation fusionierte und deren hundertprozentige Tochtergesellschaft wurde.

Gemäß den Fusionsbedingungen wurde jede Akoya-Aktie gegen 0,1461 Quanterix-Aktien plus 0,38 USD in bar getauscht, vorbehaltlich möglicher Anpassungen. Nach dem Abschluss meldet Winkler nun keine AKYA-Aktien mehr im wirtschaftlichen Eigentum.

Die Meldung offenbart außerdem die Stornierung von 153.731 Aktienoptionen mit Ausübungspreisen zwischen 2,01 und 21,95 USD, die dem oder über dem pro Aktie gezahlten Fusionspreis entsprachen; diese Optionen wurden ohne Gegenleistung beendet.

Es sind keine Börsengeschäfte, Preisdaten oder neue Finanzkennzahlen enthalten – dies ist eine rein formale Offenlegung im Zusammenhang mit der abgeschlossenen Fusion.

Positive
  • Merger consideration disclosed: Each AKYA share converts into 0.1461 Quanterix share plus $0.38 cash, providing shareholders with liquidity and ongoing equity exposure.
Negative
  • 153,731 stock options cancelled: All outstanding options held by the director were terminated for no consideration because their exercise prices exceeded the merger value.

Insights

TL;DR: Administrative Form 4 records conversion of Akoya shares to Quanterix stock and cash; no incremental valuation signal.

The filing confirms the 07/08/2025 close of the Quanterix–Akoya merger and documents director Matthew Winkler’s disposition of 984,513 AKYA shares. The exchange ratio (0.1461 QTRX + $0.38) matches the previously disclosed agreement, so investors learn nothing new about deal economics. All 153,731 stock options were cancelled because their exercise prices exceeded the merger consideration, preventing dilution. The disclosure is routine and should have minimal market impact.

TL;DR: Filing evidences completion of merger and tidy-up of insider holdings; governance impact neutral.

This Form 4 complies with Section 16 requirements during a change-of-control event. Using code J clarifies the involuntary nature of the share conversion and option cancellation. Eliminating out-of-the-money options for no consideration avoids excessive insider payouts and aligns compensation with post-merger realities. Overall, the governance signal is neutral—proper disclosure, no unusual benefits, and no remaining insider stake in the now-private subsidiary.
