Spinning off the network business as Macnica Networks (2004)

What it means to give a business its own company

What the 2004 spin-off moved was less the content of the business than the yardstick applied to it. Kept on the same income statement as semiconductors, a network business worth barely a tenth of sales — and loss-making in some years — was buried in the swings of the chip line and hard to make the object of any judgement. Given its own legal entity, it could set its balance sheet, its headcount plan and its hiring by its own measure. When President Kamiyama Haruki laid out the targets for the year to March 2005 at an earnings briefing, they were filled with numbers for PLDs and communications ICs: the parent’s gaze was on semiconductors. Precisely for that reason, there was a point in preparing a place outside that line of sight.

Macnica Networks, so detached, was absorbed into the operating company Macnica in October 2021, having lasted seventeen years as a legal entity. The reason given was to combine semiconductors and networks in one company and build proposals with strength in both the physical and the cyber world. Pulling a separated business back into the parent looks less like an admission that the spin-off failed than a rejoining after the unit had been raised to maturity on its own accounts. That the network business earned a third of group operating profit in the year to March 2025 is the measure of what those seventeen years contained.
