Key Points

  • Morgan Stanley maintains an In-Line rating on Japan's tire sector while issuing Equal-weight or Overweight ratings at the stock level.
  • Bridgestone and Yokohama Rubber reported positive second-quarter outcomes, beating consensus on operating profit and business profit respectively.
  • Sumitomo Rubber trimmed guidance despite a strong year-over-year profit increase; Toyo Tire posted a significant profit decline and cut guidance but retained an Overweight rating.

Morgan Stanley assessed second-quarter results from Japan's major tire manufacturers and concluded the industry is producing a range of outcomes. The investment bank maintained an In-Line rating on the sector overall while assigning stock-specific views that reflect varying operational and market circumstances.

Bridgestone

Morgan Stanley described Bridgestone's second quarter as positive. The company reported adjusted operating profit of ¥158.7 billion, up 28.8% year-over-year, supported by volumes that returned to growth and favorable foreign exchange movements. Management left full-year guidance unchanged at ¥515.0 billion. Morgan Stanley notes potential upside to Bridgestone's outlook if the company continues to capture market share in North America. The firm assigns Bridgestone an Equal-weight rating and flags price competition in the small tire segment as a continuing risk.

Bridgestone's adjusted operating profit of ¥158.7 billion was reported as above consensus, which Morgan Stanley cites at ¥120 billion, with the bank highlighting market share gains despite challenging conditions.

Yokohama Rubber

Yokohama Rubber's quarter was also judged positive by Morgan Stanley. Business profit rose 35.1% year-over-year to ¥51.4 billion, with the firm attributing the improvement to favorable foreign exchange, lower raw material costs, and better price and mix. Management raised full-year guidance from ¥188.0 billion to ¥192.5 billion. Morgan Stanley sees additional upside potential, pointing to what it views as conservative second-half assumptions on fixed costs and pricing, and to possible synergies from the integration of OHT. The broker assigns Yokohama Rubber an Equal-weight rating and notes the company's profit beat consensus expectations of about ¥45 billion.

Sumitomo Rubber

Sumitomo Rubber's results were labeled neutral. Although second-quarter business profit jumped 62% year-over-year, the company lowered full-year guidance from ¥112.0 billion to ¥96.0 billion. Management cited weaker expected momentum in Europe and North America in the second half as the reason for the revision. Morgan Stanley points out that downside appears limited because of ongoing cost reductions under the "Project ARK" program and brand-strengthening measures for Dunlop. The firm rates Sumitomo Rubber Equal-weight.

Toyo Tire

Morgan Stanley characterized Toyo Tire's quarter as negative, reporting a 34.4% year-over-year decline in operating profit. The drop was linked to system disruptions and weak volumes, prompting management to cut guidance to ¥90.0 billion. Despite the setback, Morgan Stanley maintains an Overweight rating on Toyo Tire, citing expectations for a sales rebound in the second half, resolved shipment issues, strong WLTR demand, the dissolution of the Mitsubishi Corp alliance, and a share buyback program intended to lift return on equity.

Sector view

Overall, Morgan Stanley's In-Line rating reflects a differentiated operating backdrop across Japan's tire makers, with company-level fundamentals and near-term headwinds shaping earnings trajectories.


Key points

  • System disruptions and weak volumes contributed to Toyo Tire's profit decline and represent an operational risk for the company.
  • Sumitomo Rubber's lowered guidance reflects uncertainty around second-half momentum in Europe and North America, exposing the company to regional demand weakness.
