July 10, 2026 — SEALSQ Co p (NASDAQ: LAES) (“SEALSQ” o “Compa y”), a compa y that focuses o developi g a d selli g Semico ducto s, PKI, a d Post-Qua tum tech ology ha dwa e a d softwa e p oducts, a d Quobly, a pio ee i silico based qua tum computi g, today a ou ced the sig i g of a $5 millio comme cial ag eeme t u de which Quobly will i teg ate SEALSQ qua tum-secu ity tech ologies, secu e semico ducto solutio s a d elated e gi ee i g a d i teg atio se vices.

The ag eeme t ep ese ts a sig ifica t milesto e i the st ategic collabo atio a ou ced by the two compa ies i Novembe 2025 a d follows SEALSQ’s st ategic i vestme t i Quobly.

U de the ag eeme t, SEALSQ will p ovide Quobly with a po tfolio of post-qua tum secu ity tech ologies desig ed to p otect the ha dwa e, co t ol systems, commu icatio s i f ast uctu e a d t usted executio e vi o me ts equi ed by ext-ge e atio qua tum computi g platfo ms.

The collabo atio is expected to i clude the i teg atio a d deployme t of SEALSQ’s qua tum- esista t tech ologies, i cludi g:

• C yo CMOS ASIC fo qua tum computi g a chitectu e
• Post-qua tum secu e semico ducto a chitectu es a d secu e eleme ts

• E gi ee i g, i teg atio a d secu ity a chitectu e se vices suppo ti g the developme t of secu e a d scalable qua tum computi g platfo ms.

The comme cial ag eeme t combi es Quobly’s CMOS-compatible silico spi qubit tech ology a d scalable qua tum p ocesso a chitectu e with SEALSQ’s post-qua tum semico ducto tech ologies a d ha dwa e-based Root-of-T ust i f ast uctu e.

The objective is to develop qua tum computi g systems i which cybe secu ity is i teg ated di ectly i to the ha dwa e a chitectu e f om the ea liest stages of system desig .

As qua tum compute s evolve f om labo ato y systems towa d i dust ial-scale i f ast uctu e, secu i g qua tum p ocesso s, c yoge ic co t ol elect o ics, classical computi g systems, commu icatio s etwo ks a d cloud i te faces is becomi g i c easi gly impo ta t.

SEALSQ a d Quobly i te d to add ess this challe ge by developi g a secu ity a chitectu e whe e qua tum computi g i f ast uctu e ca be authe ticated, p otected a d ma aged th ough ha dwa e-based ide tities a d post-qua tum c yptog aphy.

Ca los Mo ei a, Fou de a d CEO of SEALSQ, comme ted:

“The sig i g of this $5 millio comme cial ag eeme t ep ese ts a impo ta t milesto e i the executio of SEALSQ’s qua tum st ategy a d demo st ates the g owi g comme cial dema d fo post-qua tum semico ducto tech ologies.

Ou collabo atio with Quobly is movi g f om st ategic tech ology coope atio towa d comme cial deployme t.
