What Tosoh does

Makes petrochemicals, specialty chemicals, cement and diagnostic instruments.

Rests on chlor-alkali, the salt-and-electricity process that gives caustic soda and chlorine, and on the plastics made from them, whose prices swing with the economic cycle. Alongside sits a specialty line of zirconia powders, laboratory chromatography media and hospital diagnostic instruments, sold on technical qualification rather than price.

In one line: A diversified chemicals maker like a smaller Celanese.

Questions

Who are Tosoh's main competitors?
Named competitors: Shin-Etsu Chemical (4063.T), Mitsui Chemicals (4183.T), Celanese (CE). The cockpit's measured peer set (industry) also includes Red Avenue New Materials (603650.SS), Dottikon ES (DESN.SW), Zhejiang Sanmei Chemical Industry (603379.SS), Far Eastern New Century (1402.TW), Navin Fluorine International (NAVINFLUOR.NS), Sumitomo Chemical (4005.T).
Is Tosoh expensive compared with its peers?
On forward p/e it trades at 11.4× against a peer median of 22.7×, 4th cheapest of 21 in its peer set. For today's price to make sense, revenue must grow about -1% a year for seven years (Req g). Recent delivered growth is +7%, so the hurdle is -8 pp: the price already allows for a slowdown.
How has Tosoh stock performed?
Over six months to 6 Nov 2026 the shares returned -3.8% against -17.1% for the median peer; over one year +5.1%.

How these numbers are made. Returns are close-to-close in local currency. Revenue growth and margins are trailing twelve months. Req g is the revenue growth that today's enterprise value requires for seven years at the company's own cost of capital; Delivered g is what it actually grew; the gap is the hurdle (honest precision about ±8 points, so read the ranking more than the decimal). No fair values, price targets or analyst ratings are shown, by design. Method and validation.
