Heavy Industry, Defense and Energy Machinery FY2026 Full Year: MHI leads, margins diverge

Average revenue growth across the six companies was 6.6%, while their average operating margin was 6.8%. The tailwinds were broadly shared, but companies differed in how effectively they converted them into profit.

• Defense demand supported the heavy industry companies. Rising geopolitical risks expanded projects involving defense equipment and space.
• Energy and power infrastructure were also growth areas. Decarbonization investment, along with electricity demand from AI and data centers, provided support.
• A recovery in aviation demand contributed to earnings. IHI benefited from maintenance demand for commercial aircraft engines.
• Companies continued to reshape their portfolios. Transfers of unprofitable businesses and asset sales featured prominently as companies sought to improve margins and capital efficiency.

Strong orders, selective profits was the defining theme of the period. The test is whether companies can reliably turn large projects into earnings.

The overall winner was MHI. Revenue reached 4.9742 trillion yen, the highest among the six, rising 14.1% from a year earlier despite the company's already large scale. Operating profit also led the group at 432.2 billion yen, up 21.8%. Growth in defense, space and energy helped MHI combine scale with strong growth.

IHI led on profitability, with an operating margin of 10.1%, ahead of MHI's 8.7%. Growth in commercial aircraft engines and defense, along with business restructuring and asset sales, supported earnings.

The loser was Kanadevia. Revenue rose 5.7% to 645.2 billion yen, but operating profit fell 54.8% to 12.2 billion yen. Its 1.9% operating margin was the lowest among the six. Technical problems at an overseas subsidiary and weakness in its machinery and decarbonization businesses weighed on results.

Kanadevia's orders, however, hit a record 897.7 billion yen. A recovery will depend on converting those orders into profitable sales.

The companies are not just pursuing demand growth. They are also reshaping their businesses to prioritize more profitable operations.

• MHI was driven by defense, space and energy. Orders reached 7.6536 trillion yen, building a pipeline of projects to support future revenue.
• IHI continued to exit unprofitable businesses and sell assets. Revenue edged up 1.0%, while operating profit increased 15.3%. Its 10.1% operating margin ranked first.
• Kawasaki benefited from aerospace and robotics. Revenue rose 8.5%, but operating profit grew just 1.4% as weaker profitability in powersports restrained earnings growth.
• SHI reported a 24% rise in orders to 1.1584 trillion yen. Revenue fell 0.4% and operating profit declined 6.6%, putting the conversion of orders into sales in focus. Net profit surged 300.7%, partly reflecting the absence of impairment losses recorded in the previous period.
• Kanadevia set a new record for orders, but technical problems contributed to a 54.8% drop in operating profit. Execution and quality control will be crucial to turning its order backlog into earnings.
• JSW captured demand from defense and power infrastructure. Revenue rose 10.6% and operating profit increased 10.9%. It is also moving to absorb a subsidiary involved in improper conduct as part of efforts to strengthen governance.

MHI stood out for scale, while IHI led on margins. Strategies are shifting from growth at any cost toward greater focus on profitability.

Even with strong demand, profits can erode if the economics of large projects or supply chains deteriorate. Investors and employees alike should look beyond order totals to a company's ability to execute.

• Project profitability: Higher material and labor costs can squeeze earnings on long-term contracts.
• Technical and quality problems: Failures on overseas projects, such as those affecting Kanadevia, can bring additional costs and damage customer confidence.
• Demand volatility: Aviation, semiconductors and private-sector capital spending can shift with the economy and customers' investment plans.
• Currency and trade policy: Exchange-rate and tariff changes can affect export profitability and customers' investment decisions.
• Workforce and supply chains: Production capacity and access to specialized talent may fail to keep pace with rising defense and energy orders.
• Regulation and governance: Compliance with security, environmental and quality requirements can affect costs and business continuity.

MHI ranked first in both revenue and operating profit. IHI led on operating margin, underscoring that company size and profitability do not produce the same ranking.

MHI also had the fastest revenue growth, up 14.1%. JSW posted strong growth of 10.6%, while SHI revenue declined 0.4%. SHI's net profit rose 300.7%, but operating profit fell, making it important to distinguish the sources of its earnings recovery.

Fiscal-year timing also matters in comparisons. SHI's results cover the year ended December 2025, while the other companies reported for the year ended March 2026.

Growing demand in defense, aviation and power infrastructure is creating opportunities in engineering, quality control, procurement and project management. Work on large projects requires not only technical expertise but also the ability to coordinate across teams and with external partners.

At the same time, more orders can put pressure on deadlines and staffing. When evaluating employers, look beyond growth sectors to how they manage project profitability and maintain safety and quality. Kanadevia's earnings decline shows how significantly technical problems can affect business performance.
