Stanley Electric and Mitsubishi Mobility said they will move the effective dates of their planned absorption-type company split agreements to January from October, a scheduling change tied to the creation of a joint venture focused on electronic and control components for automotive lamp systems.
The new timing gives the partners more runway to align closing steps and regulatory clearances flagged earlier in the process.
The venture will bundle Stanley’s electronics related to lamp systems with Mitsubishi Electric Mobility’s lighting control equipment business for next-generation vehicles, including software-defined and autonomous platforms.
In April, the companies set out a framework for the split transactions and targeted early October effective dates, subject to regulatory approvals.
They also outlined a structure in which a preparatory company formed by Stanley would absorb the designated businesses from each partner under Japan’s Companies Act, a mechanism commonly used to carve out operations into a new entity while keeping continuity of contracts and personnel under the successor company.

The approval condition on that plan was explicit, and today’s adjustment keeps the deal sequence intact while moving the calendar.
Under the integration agreement disclosed in April, Stanley will ultimately hold 66 percent of the joint venture and Mitsubishi Electric Mobility will own 34 percent after share adjustments on the split’s effective date.
The venture is intended to compete as a full-system supplier as lighting becomes more tightly integrated with vehicle software and sensing.
The companies argue that combining hardware, control electronics, and software development can shorten model cycles and help win programs as automakers retool lighting for safety features and brand signatures.
The original timetable called for Mitsubishi Electric Mobility’s split to take effect one day before Stanley’s. The partners have now synchronized on a January window.
They did not publicly detail a specific day in January, nor did they cite a single driver for the rescheduling.
In corporate reorganizations of this type, timing shifts often reflect clearance milestones, operational readiness, and closing mechanics such as asset lists and IT separation, rather than a strategic rethink of the transaction itself.
The April documentation already noted that the integration’s effectiveness depended on approvals from competition and other authorities in Japan and overseas.
The change pushes out the point at which the joint venture begins consolidated operations, but it does not alter the industrial logic or the targeted ownership split for investors.
The partners have reiterated the plan several times since announcing a basic agreement last year, and they established the successor company that will receive the businesses in preparation for the split.
In a July update, they also disclosed the joint venture’s name, Stanley Mobility Electric Co., Ltd., and restated the intended scope: development, design, manufacturing, and sales of electronic and control parts that sit inside lamp systems for four-wheel and two-wheel vehicles.
An absorption-type split in Japan transfers designated rights and obligations to the successor company by operation of law, which typically allows operations to continue with minimal disruption on day one.
By resetting the effective dates to January, Stanley and Mitsubishi Electric Mobility are positioning the venture to start the new calendar year with the core businesses under one roof, a cleaner kickoff for planning and reporting.
The partners have not changed the underlying deal terms in their latest notices. The move to January is about timing, not substance.
If approvals arrive on the revised schedule, the joint venture will begin life with a fresh year in front of it and a mandate to scale as lighting technology becomes a bigger lever in vehicle differentiation.
