Sumitomo Electric reported first-half fiscal 2026 (ending March 2027) net profit of JPY 159.4 billion, up 63% year over year. Revenue rose 17%, driven by growth in automotive and infocomms. Operating profit rose 44%, supported by a weaker yen and higher copper prices. Profit guidance rose 9%.
Info-communications is a genuine structural growth driver of hyperscale data center demand, supported by aggressive, already-committed capacity expansion.
Bears
Data center/AI capex is now a major swing factor for group profits, and a slowdown in hyperscaler spending or share loss to competitors would hit the highest-growth, highest-multiple segment disproportionately.
