From commodity ASSPs to custom-only: the Solution SoC model (2018)

Discarding the industry standard

The core of this pivot is less a story of catching a wave than of discarding the semiconductor industry’s standard model itself — selling volume. The way Nvidia and Qualcomm recover their investment by selling large quantities of off-the-shelf parts was also the trajectory Socionext had been placed on before the merger. That Hizuka Masahiro called 2018 the company’s “first turning point” and deliberately closed off the road of competing on volume with the mega-players says what kind of decision this was. Cutting domestic sales from nearly 70% to under 40%, and climbing to a 12% share and the world’s number two position in custom SoCs for American and Chinese customers, followed from redefining the firm as one that sells design rather than scale.

Choosing not to chase volume did not, however, guarantee stable results. A design-selling model embeds itself deeply in each customer’s programme, and so tends to accumulate concentration on particular customers. That the year to March 2025 brought the first decline since the merger, with a large Chinese customer’s inventory correction halting the next order, is the other side of the same coin. Abandoning thin margins on high volume in favour of the added value of bespoke work also meant giving up the defensive smoothing that scale provides. Rejecting the industry standard was equally a choice to take on a different kind of risk.
