Rhea-AI Filing Summary

SigmaTron International, Inc. (SGMA) filed Post-Effective Amendment No. 1 to seven prior Form S-8 registration statements in connection with its 28 Jul 2025 merger with Transom Axis AcquireCo, LLC. Because the company has been merged into a wholly-owned subsidiary of the acquirer, all employee and director equity incentive offerings have been terminated. The amendment therefore deregis­ters all shares that were previously registered but remain unsold under the following plans:

  • 2021, 2019 & 2013 equity plans � 1,021,915 shares
  • 2011 & 2004 plans � 450,000 shares
  • 2000 plans � 560,000 shares
  • 1997 plan � 105,000 shares
  • 1994 & 1993 plans � shares previously registered (exact count not restated)

In aggregate, more than 2.1 million unsold shares of common stock are being withdrawn from registration. The filing formally terminates the effectiveness of all seven registration statements and requires no additional signatures under Rule 478.

SigmaTron International, Inc. (SGMA) ha presentato l'Emendamento Post-Esecutivo n. 1 a sette precedenti dichiarazioni di registrazione Form S-8 in relazione alla fusione del 28 luglio 2025 con Transom Axis AcquireCo, LLC. Poiché la società è stata fusa in una controllata interamente posseduta dall'acquirente, tutte le offerte di incentivi azionari per dipendenti e dirigenti sono state terminate. L'emendamento quindi deregistra tutte le azioni precedentemente registrate ma non ancora vendute secondo i seguenti piani:

  • Piani azionari 2021, 2019 e 2013 � 1.021.915 azioni
  • Piani 2011 e 2004 � 450.000 azioni
  • Piani 2000 � 560.000 azioni
  • Piano 1997 � 105.000 azioni
  • Piani 1994 e 1993 � azioni precedentemente registrate (numero esatto non specificato)

In totale, oltre 2,1 milioni di azioni ordinarie invendute vengono ritirate dalla registrazione. Il deposito termina formalmente l'efficacia di tutte e sette le dichiarazioni di registrazione e non richiede firme aggiuntive ai sensi della Regola 478.

(SGMA) presentó la Enmienda Post-Efectiva No. 1 a siete declaraciones de registro Formulario S-8 previas en relación con su fusión del 28 de julio de 2025 con Transom Axis AcquireCo, LLC. Debido a que la compañía se ha fusionado en una subsidiaria de propiedad total del adquirente, todas las ofertas de incentivos accionarios para empleados y directores han sido terminadas. Por lo tanto, la enmienda desregistra todas las acciones que estaban previamente registradas pero que permanecen sin vender bajo los siguientes planes:

SigmaTron International, Inc. (SGMA) a déposé un amendement post-efficace n°1 à sept déclarations d'enregistrement Formulaire S-8 antérieures en lien avec sa fusion du 28 juillet 2025 avec Transom Axis AcquireCo, LLC. Comme la société a été fusionnée dans une filiale détenue à 100 % par l'acquéreur, toutes les offres d'incitations en actions pour les employés et les administrateurs ont été arrêtées. L'amendement déréférence donc toutes les actions précédemment enregistrées mais non vendues dans le cadre des plans suivants :

  • Plans d'actions 2021, 2019 et 2013 � 1 021 915 actions
  • Plans 2011 et 2004 � 450 000 actions
  • Plans 2000 � 560 000 actions
  • Plan 1997 � 105 000 actions
  • Plans 1994 et 1993 � actions précédemment enregistrées (nombre exact non précisé)

Au total, plus de 2,1 millions d'actions ordinaires invendues sont retirées de l'enregistrement. Le dépôt met formellement fin à l'efficacité des sept déclarations d'enregistrement et ne nécessite aucune signature supplémentaire conformément à la règle 478.

SigmaTron International, Inc. (SGMA) reichte eine Nachwirkungsänderung Nr. 1 zu sieben früheren Form S-8-Registrierungserklärungen im Zusammenhang mit der Fusion am 28. Juli 2025 mit Transom Axis AcquireCo, LLC ein. Da das Unternehmen in eine hundertprozentige Tochtergesellschaft des Erwerbers eingegliedert wurde, wurden alle Aktienanreizangebote für Mitarbeiter und Direktoren beendet. Die Änderung streicht daher alle zuvor registrierten, aber noch nicht verkauften Aktien unter den folgenden Plänen aus der Registrierung:

  • Aktienpläne 2021, 2019 & 2013 � 1.021.915 Aktien
  • Pläne 2011 & 2004 � 450.000 Aktien
  • Pläne 2000 � 560.000 Aktien
  • Plan 1997 � 105.000 Aktien
  • Pläne 1994 & 1993 � zuvor registrierte Aktien (exakte Anzahl nicht erneut angegeben)

Insgesamt werden mehr als 2,1 Millionen unverkaufte Stammaktien aus der Registrierung zurückgezogen. Die Einreichung beendet formell die Wirksamkeit aller sieben Registrierungserklärungen und erfordert keine weiteren Unterschriften gemäß Regel 478.

Positive
  • Merger completion confirmed, providing final clarity that SigmaTron is now a wholly-owned subsidiary of Transom Axis AcquireCo.
Negative
  • All outstanding registered equity awards withdrawn, ending any ability to issue shares under legacy employee and director stock plans.

Insights

TL;DR: Procedural filing—deregisters >2 M incentive shares after completion of merger; limited standalone valuation impact.

The amendment is a routine post-merger housekeeping step. Once SigmaTron became a wholly-owned subsidiary of Transom Axis AcquireCo on 28 Jul 2025, its public equity incentive plans ceased. Consistent with undertakings in each S-8, the company must remove from registration any securities no longer offered. By withdrawing ~2.1 M shares across 11 historic employee & director plans, the firm eliminates lingering SEC reporting obligations and potential registration fees. The action neither alters merger economics nor affects the consideration already delivered to former public shareholders; it simply cleans the corporate record. Impact on current investors is therefore neutral, but participants with unexercised options may now rely on merger-specified treatment rather than public market settlement.

FAQ

Why did SigmaTron (SGMA) file this Post-Effective Amendment?

Because the 28 Jul 2025 merger closed, the company ended all equity offerings and is deregistering unsold shares from seven prior S-8 filings.

How many SigmaTron shares are being deregistered?

The filing withdraws over 2.1 million unsold shares that were previously allocated to various employee and director stock plans.

Which stock plans are affected by the deregistration?

Plans from 1993 through 2021, including the 2021 Employee Stock Option Plan and 2000 Employee & Director Stock Option Plans, are terminated.

Does this filing impact the merger consideration for former SGMA shareholders?

No. The amendment is administrative and does not change the merger terms already executed on 28 Jul 2025.

Are further SEC filings required for these plans?

No. The company states the registration statements are now terminated and Rule 478 waives additional signatures.
