Cement and Carbon Products Q1 FY2027: Nichias tops on AI-led margins

• AI and semiconductor demand lifted sales of advanced products. Nichias's revenue rose 16.0% year on year and operating profit increased 20.7%. Tokai Carbon also posted gains of 9.9% in revenue and 10.5% in operating profit.
• Weak domestic cement demand persisted as high construction costs and labor shortages weighed on the market. Taiheiyo Cement offset the pressure with stronger exports and overseas business, lifting revenue 5.1% year on year.
• Profit margins diverged sharply. Nichias led at 15.5%, ahead of Tokai Carbon at 8.7% and Taiheiyo Cement at 5.2%. Growth in advanced products supported Nichias's profitability.
• Shareholder returns also increased. Taiheiyo Cement plans a ¥10 billion share buyback and an annual dividend of ¥120 per share. Tokai Carbon expects to raise its annual dividend to ¥40 from ¥30.

*Taiheiyo Cement and Nichias reported first-quarter results for the year ending March 2027. Tokai Carbon reported interim results for the year ending December 2026, so the reporting periods differ.*

Nichias was the winner. Revenue was ¥72.0 billion, the smallest among the three, but grew 16.0% year on year, the fastest rate. Operating profit rose 20.7% to ¥11.1 billion, and its 15.5% operating margin was the highest.

Against a backdrop of AI investment, sales of advanced products for semiconductor manufacturing equipment surged 42.3%. Revenue grew in every segment, giving the company a broader source of growth than any single business area.

Tokai Carbon struggled most on net profit. Revenue reached ¥173.7 billion and operating profit ¥15.1 billion, both higher year on year. Net profit, however, fell 14.0% to ¥7.2 billion. Higher feedstock costs, including for carbon black, made it harder to translate operating gains into bottom-line growth.

Taiheiyo Cement was the largest by revenue, at ¥221.9 billion. Its 5.1% revenue growth was the slowest of the three, but operating profit rose 13.9% and net profit increased 22.3%. Overseas business and exports helped offset weak domestic demand.

• Taiheiyo Cement is using exports and overseas business to make up for declining domestic demand. It also announced a ¥10 billion share buyback and plans to raise its annual dividend by ¥20 per share from the previous year, to ¥120.
• Tokai Carbon benefited from demand related to AI and semiconductor manufacturing equipment, and raised its full-year forecast. It also expects to increase its annual dividend to ¥40 from ¥30. Net profit was still down 14.0% year on year, making a recovery in the second half a key focus.
• Nichias raised its full-year forecast after a sharp increase in advanced products for semiconductor equipment. Its 15.5% operating margin was well above Tokai Carbon's 8.7% and Taiheiyo Cement's 5.2%.

Each company has a different growth engine: advanced products for Nichias, materials and equipment demand for Tokai Carbon, and overseas expansion for Taiheiyo Cement.

• Demand swings: Nichias and Tokai Carbon are exposed to a slowdown in semiconductor and AI investment. Recent growth in advanced products may not last.
• Materials and costs: Higher feedstock costs weighed on Tokai Carbon's profit. Cement producers also need to pass energy and logistics expenses through to selling prices.
• Weak domestic construction: Taiheiyo Cement faces falling demand, labor shortages and rising construction costs. Greater reliance on exports and overseas business could also increase exposure to local political and economic risks.
• Operating profit and net profit can diverge: As Tokai Carbon's results show, operating profit can rise even as net profit falls. Investors should also track factors such as raw material costs and depreciation.
• Different reporting periods: Tokai Carbon reported half-year results, while the other two companies reported first-quarter results. Seasonality and progress through the year matter, so direct comparisons require caution.

Taiheiyo Cement ranked first in revenue at ¥221.9 billion, followed by Tokai Carbon at ¥173.7 billion and Nichias at ¥72.0 billion. But Nichias led on operating margin at 15.5%, showing that scale and earnings power produce different rankings.

Revenue growth was fastest at Nichias, up 16.0% year on year, followed by Tokai Carbon at 9.9% and Taiheiyo Cement at 5.1%. Companies with advanced products are leading on growth, although Tokai Carbon's figures cover a half-year period and should be viewed with that difference in mind.

Even within the glass, ceramics and cement sector, the work varies widely. Growth areas include domestic infrastructure and overseas business at Taiheiyo Cement, materials development and plant operations at Tokai Carbon, and products for semiconductor equipment at Nichias.

Those prioritizing exposure to AI and semiconductor demand may consider related businesses at Nichias or Tokai Carbon. They should also weigh resilience to economic swings and the breadth of each company's operations. Taiheiyo Cement's overseas expansion and Nichias's growth across all segments are examples of breadth worth considering.
