Sumitomo Chemical stock is back in the spotlight after the Japanese chemical group reported a sharp recovery in earnings for the quarter ended June 30, 2026 and outlined an ambitious plan to grow new semiconductor materials businesses toward JPY 10 billion in sales by the mid-2030s.

Semiconductor materials push underpins growth story

According to a sector report published on September 3, 2026 by TrendForce, Sumitomo Chemical has begun commercial mass production of 4-inch indium phosphide (InP) epitaxial wafers, targeting JPY 10 billion in annual sales from this product line by the mid-2030s.

The move into InP wafers positions Sumitomo Chemical to benefit from rising demand in optoelectronics and high-speed communications, adding a more specialized, higher-margin segment to its broad chemical portfolio.

Earnings rebound in fiscal 2026 first quarter

A performance overview compiled on September 3, 2026 by Echemi for major global chemical companies shows that Sumitomo Chemical delivered a significant earnings rebound in its first fiscal quarter of 2026, which ended on June 30, 2026.

In that quarter, Sumitomo Chemical generated revenue of JPY 5,782.0 billion, up from JPY 5,261.0 billion in the same period a year earlier, an increase of about 9.9 percent year on year.

Operating profit in the quarter rose to JPY 610.0 billion compared with JPY 255.0 billion in the prior-year period, meaning operating profit expanded by roughly 139 percent year on year.

The turnaround was most visible at the bottom line: quarterly net profit attributable to owners reached JPY 408.0 billion, compared with a net loss of JPY 45.0 billion in the same quarter of the previous year, implying an improvement of JPY 453.0 billion.
