Mitsubishi Heavy Industries' Order Backlog Hits $82 Billion — Can Capacity Expansion Keep Up?
Alina Collins
Mitsubishi Heavy Industries has amassed an $82 billion order backlog, driven by AI-datacenter gas-turbine demand and Japan's defense spending surge; yet its stock is down ~17% this year, as the market's core worry shifts from winning orders to delivering them on time.
Where does $82 billion in orders come from?
AI datacenters are the biggest driver: MHI's 2025 turbine orders are worth roughly four times the 2019–2022 annual average. The company forecasts industry-wide orders of 70 GW per year over the next five years — nearly double the normal level.
Japan's defense budget has doubled in four years to $66 billion in FY2026. Tokyo opened lethal-weapons exports in April; MHI is building frigates for Australia and co-developing a next-generation fighter jet with the UK and Italy (the GCAP program).
This means → MHI is riding two demand curves at once — AI power infrastructure and geopolitical rearmament — producing a backlog unprecedented in the company's history.
What has this done to the financials?
For the first time since MHI began reporting consolidated results in 1999, the company posted positive annual net cash — ¥6.4 billion in 2024, surging to ¥819 billion by March this year.
The stock has risen nearly fivefold since early 2024.
In plain terms = MHI spent decades running with more debt than cash. Now, for the first time, it has more cash than debt — and the surplus is growing fast.
Why is the stock falling anyway?
Despite the record backlog, MHI shares are down ~17% year-to-date, underperforming the Topix and Japanese industrials broadly.
Citi analyst Graeme McDonald: "The momentum is fading. Are they moving fast enough? Not entirely convincing."
This means → the market's anxiety has shifted. The fear is no longer a lack of orders — it is that capacity cannot keep up, turning the backlog into revenue MHI cannot actually capture.
How does MHI plan to expand capacity?
CEO Eisaku Ito has launched an efficiency program targeting a 50% cut in lead times and an effective doubling of capacity — but with no firm completion date.
He recently said output would rise beyond the initial FY2028 target of +30%, roughly doubling total production versus 2024.
Management frames the large cash buildup as customer prepayments that will be drawn down during execution. From March 2027, surplus cash will go toward working capital and plant expansion, alongside an undisclosed "cash buffer" for external shocks.
Are competitors catching up?
The gas-turbine market is an oligopoly: MHI, GE Vernova, and Siemens Energy. But new entrants are pushing in.
Elon Musk's xAI chose South Korea's Doosan Enerbility to supply large turbines for its supercomputing center. China's Jereh Group saw its stock surge after winning a $341 million turbine-generator order in the US.
Dora Partners president Tony Brough's assessment: newcomers remain a considerable distance behind the big three on technology — no immediate threat.
What is the biggest risk?
MHI has proactively shed non-core assets to concentrate resources: it canceled the ¥1 trillion+ Mitsubishi Regional Jet (MRJ) program in 2023 and sold a majority stake in its forklift subsidiary for $464 million last year.
But Brough also warns: the risk of a global recession triggered by an Iran conflict is real. Any slowdown in datacenter activity would weigh on every turbine maker.
In plain terms = whether $82 billion in backlog converts to actual revenue depends on two races — whether MHI's capacity ramp can outrun the closing of the demand window, and whether the macro environment hits the brakes first.
